Description

Vehicle and base

This disclosure pertains to the vehicle and its base.

Existing infant car seats feature ISOFIX anchoring components. Some ISOFIX anchoring components cannot be folded by rotation. This means that when the ISOFIX anchoring components are not needed, they cannot be folded down to reduce storage volume. This makes the ISOFIX anchoring components appear obtrusive, affecting both appearance and usability. While some infant car seats have rotating ISOFIX anchoring components, the rotation is completely unrestricted. Therefore, when it is necessary to adjust the ISOFIX anchoring components to a specific angle, it is impossible to lock them at that angle, causing inconvenience in use.

It should be noted that the above description of the prior art is merely a background introduction and does not constitute an acceptance that the above prior art constitutes the prior art of this disclosure, nor should any description of the above prior art be considered part of this disclosure.

This disclosure discloses a vehicle including a passenger body and a pivoting part pivoting relative to the passenger body, wherein the vehicle further includes a gear shifting structure configured in conjunction with the pivoting part, the gear shifting structure being operable to lock the pivoting part relative to the passenger body in one of a plurality of pivoting positions.

This disclosure further discloses a base for mounting the aforementioned vehicle, the base being connectable to a vehicle seat, wherein the vehicle includes two pivots connected between the two pivots by a front connecting shaft, and the base includes: a base engagement member disposed on the base and movable between an engaged position and a non-engaged position, wherein the base engagement member is engaged with the front connecting shaft in the engaged position and disengaged from the front connecting shaft in the non-engaged position; and a base operating member movably disposed on the base and configured to directly or indirectly drive the base engagement member toward the non-engaged position.

This disclosure further discloses a vehicle application device capable of connecting to a vehicle, including an application retaining part that engages with a vehicle retaining part on the vehicle, thereby allowing the vehicle to be positioned within the vehicle application device.

This disclosure also proposes a pressing structure capable of pressing a first object against a second object. The pressing structure includes: a base disposed on the first object; a pressing member mounted on the base and capable of pivoting relative to the base about a first pivot axis between a retracted position and an extended position, pressing against the second object; and a biasing member mounted on the pressing member and abutting against the base to push the pressing member toward the extended position.

This disclosure further discloses a support device, comprising: a seat body; a support portion; and a support structure according to this application, disposed on the support portion; wherein the first object is the support device, and the second object is a vehicle seat.

The beneficial effect of this disclosure is that the vehicle according to this disclosure can fix the anchoring assembly in multiple pivot positions, thereby facilitating storage and easy locking of the anchoring angle. Furthermore, the pivots located on both sides of the carrier body can be unlocked by operating only the drive unit on one side.

The foregoing and other objects, features, aspects, and advantages of this disclosure will become more apparent from the following detailed description of the disclosure in conjunction with the accompanying drawings.

The exemplary embodiments will be described in detail below with reference to the diagrams.

Figure 1 illustrates a vehicle 1 according to this disclosure. It should be noted that although the vehicle 1 shown in the figure is an infant safety seat, this disclosure is not limited to this. The vehicle 1 according to this disclosure can be used to carry a person, an animal, or articles, including but not limited to infant safety seats or child safety seats, sleeping bags, car seats, animal carriers, or cargo carriers. The vehicle 1 can be installed inside a vehicle. The vehicle 1 can be used with corresponding accessories anchored to a vehicle seat (not shown), such as anchoring interfaces.

To ensure a safe and reliable connection between the vehicle 1 and the vehicle seat, an anchoring assembly may be provided on the vehicle 1.

The anchoring assembly can directly engage with corresponding accessories such as connecting rods, connecting rings, and anchoring interfaces on the vehicle seat, eliminating the need for an additional base. This makes connecting vehicle 1 to the vehicle seat more convenient and simplifies the structure.

For ease of description, this paper uses a baby carrier as an example, and defines the direction the baby faces in carrier 1 as "front," the direction the baby faces away as "back," the left-right direction of the baby in carrier 1 as "lateral," the side of carrier 1 carrying the baby as the inside of carrier 1, and the opposite side as the outside of carrier 1. Other forms of carrier 1 may have structures similar to or different from a baby carrier.

The vehicle 1 may include a carrier body 300 and a pivoting part 100 that pivots relative to the carrier body 300.

The carrier body 300 can be used to carry infants or children. The pivot 100 may include anchoring components for operatively connecting to a vehicle seat. The anchoring components may be ISOFIX connectors, but this disclosure is not limited thereto.

When a user prepares to connect the vehicle 1 to the vehicle seat, they can first adjust the pivot 100 to a suitable pivot position (described later), and then engage the anchoring assembly with the corresponding accessory on the vehicle seat; alternatively, they can first engage the anchoring assembly with the corresponding accessory on the vehicle seat, and then adjust the pivot 100 to a suitable pivot position according to the position of the vehicle seat backrest, seat surface, and vehicle 1; ultimately, the leading edge 1A of the vehicle 1 (see Figures 1 to 4) is firmly pressed against the vehicle seat backrest, thereby ensuring that the vehicle 1 is safely and reliably connected to the vehicle seat.

As shown in Figures 1 and 2, in one embodiment, the vehicle 1 may include a passenger body 300, two pivots 100, two gear shifting mechanisms 400, and a connecting shaft 180. The passenger body 300 may include a cavity 320 and two sides 330. The cavity 320 is formed at the front of the passenger body 300 (the portion near the backrest of a car seat when the vehicle 1 is mounted on it). The two sides 330 are formed on opposite sides of the passenger body 300 and may be shaped as generally vertical ribs, thereby forming the cavity 320 between them. The front of the cavity 320 is open.

In one embodiment, the two pivots 100 are respectively located inside the two sides 330 and positioned at the front of the carrier body 300.

In one embodiment, the two pivot points 100 are respectively located on the outer sides of the two sides 330 and are disposed at the front of the carrier body 300.

In one embodiment, the two pivots 100 can be linked via a connecting shaft 180, allowing the two pivots 100 to pivot synchronously.

In one embodiment, the carrier 1 may not include the connecting shaft 180, allowing the two pivots 100 to pivot independently of each other.

As shown in Figures 7 and 8, in one embodiment, the vehicle 1 may include a carrying body 300, two pivots 100, two gear shifting mechanisms 400, and a synchronizing linkage assembly 200. The two pivots 100 may be located on the outer sides of two sides 330, respectively, and are linked via the synchronizing linkage assembly 200, such that the two pivots 100 pivot synchronously and that the engaging members 150 of each of the two gear shifting mechanisms 400 move the same distance in opposite directions.

In one embodiment, two pivots 100 may be located inside the two sides 330, respectively, and are linked by a synchronizing linkage assembly 200, such that the two pivots 100 pivot synchronously and that the engaging members 150 of the two gear shifting mechanisms 400 move the same distance in opposite directions.

pivot department

Although the carrier 1 disclosed herein may have two pivots 100, only one pivot 100 will be described below. It is understood that the two pivots 100 may have symmetrical structures.

In this disclosure, the pivot 100 of the vehicle 1 is pivotable relative to the passenger body 300. As shown in Figures 1-3, each side of the passenger body 300 may have a pivot 100, but this disclosure is not limited thereto. The number of pivots 100 may be provided as needed or as required by regulations. The pivots 100 may be located below the seat where an infant or child sits.

As shown in Figures 2 and 3, the pivot 100 may include an outer cover 120, a main body 130, and an inner cover 140. The outer cover 120 and the inner cover 140 together enclose a space, and the main body 130 is located within that space.

The outer cover 120 may be located outside the inner cover 140, i.e., on the side away from the vehicle body 300.

The outer cover 120 may include a base 121, an extension 122, a receiving groove 123, and a hole 124.

The base 121 of the outer cover 120 may be generally circular. An extension 122 may be provided at the edge of the base 121. In the embodiments shown in Figures 2 and 3, a receiving groove 123 is centrally formed on the base 121 and is concentrically formed with the base 121. The receiving groove 123 is recessed inward from the outer surface of the base 121. A hole 124 may be formed in the bottom wall of the receiving groove 123.

As shown in Figure 2, in one embodiment, the bottom wall of the receiving groove 123 may have four holes 124 formed therein. The four holes 124 may be arranged in pairs facing each other, but this disclosure is not limited thereto. The four holes 124 may be evenly distributed along the circumference of the receiving groove 123 on the outer edge of the bottom wall of the receiving groove 123, that is, adjacent holes are spaced 90° apart circumferentially, but this disclosure is not limited thereto.

The inner cover 140 may include a base 141, an extension 142, and a central hole 143.

The base 141 of the inner cover 140 may be generally circular. An extension 142 may be provided at the edge of the base 141. In the embodiments shown in Figures 2 and 3, a central hole 143 is centrally formed on the base 141 and is concentrically formed with the base 141.

The outer cover 120 and the inner cover 140 have corresponding shapes and can be snap-fitted together and/or engaged with each other by means of fasteners (e.g., screws). The length of the extension 142 may be less than the length of the extension 122. Both the outer cover 120 and the inner cover 140 may be formed of plastic, but this disclosure is not limited thereto.

The main component 130 may be disposed between the outer cover 120 and the inner cover 140, and may include a base 131, an extension 132, a central hole 133, and a hole 134.

The base 131 of the main body 130 may be generally circular. An extension 132 may be provided at the edge of the base 131. In the embodiments shown in Figures 2 and 3, a central hole 133 is centrally formed on the base 131 and is concentric with the base 131. The central hole 133 of the main body 130 may be smaller than the central hole 143 of the inner cover 140. A hole 134 may be formed on the outer side of the central hole 133.

The holes 134 of the body component 130 can be formed at positions corresponding to the holes 124 of the outer cover 120. The four holes 134 can be arranged in pairs facing each other, but this disclosure is not limited thereto. The four holes 134 can be evenly arranged circumferentially on the base 131, that is, adjacent holes are spaced 90° apart circumferentially. The number of holes 134 can be the same as the number of holes 124. That is, in one embodiment, the body component 130 can have four holes 134.

The body component 130 may be formed of metal (e.g., steel), but this disclosure is not limited thereto.

The main component 130 may have a locking hook 135. The locking hook 135 may be located near the free end of the extension 132. The pivot 100 may be anchored to a vehicle seat via the locking hook 135. In other words, the locking hook 135 is anchored to a corresponding accessory of the vehicle seat.

The carrier 1 may have a locking hook unlocking part (not shown) for unlocking the locking hook 135. The locking hook unlocking part may be a release wire, one end of which may be directly or indirectly connected to the locking hook 135, and the other end of which may be directly or indirectly connected to an operating element for pulling the release wire. An operating element is provided to facilitate operation of the locking hook 135, but this disclosure is not limited thereto.

In one embodiment, the connecting shaft 180 extends laterally through the passenger body 300 of the vehicle 1. Both ends of the connecting shaft 180 extend through two sides 330 of the passenger body 300, respectively. The connecting shaft 180 is freely rotatable relative to the passenger body 300. Each end of the connecting shaft 180 can be coupled to a body member 130 of a pivot 100, such that the pivot 100 rotates synchronously with the connecting shaft 180. The connecting shaft 180 can be formed of an iron pipe.

The middle portion of the connecting shaft 180 is located within the cavity 320. In one embodiment, two pivots 100 located inside the two sides 330 of the carrier body 300 may be located within the cavity 320.

When the carrier 1 has two pivots 100, each pivot 100 is coupled to one end of the connecting shaft 180. In this way, the two pivots 100 will rotate synchronously.

In one embodiment, the two pivots 100 are located inside the two sides 330 of the carrier body 300, respectively, and in this case, the two pivots 100 can be coupled to the middle portion of the connecting shaft 180.

Gear adjustment structure

The vehicle 1 also includes a gear shifting mechanism 400 coupled to the pivot 100. The gear shifting mechanism 400 can be operated to lock the pivot 100 relative to the vehicle body 300 in one of a plurality of pivot positions.

In one embodiment, the pivot angle of the pivot 100 can be 120°.

In one embodiment, the pivot angle of the pivot 100 above the horizontal plane may be greater than or equal to the pivot angle of the pivot 100 below the horizontal plane.

In one embodiment, the pivot angle of the pivot 100 above the horizontal plane may be smaller than the pivot angle of the pivot 100 below the horizontal plane.

As an example, the pivot 100 can rotate from 60.96 degrees above the horizontal plane to 59.04 degrees below the horizontal plane, but this disclosure is not limited thereto.

A recess 340 may be provided at the front of the carrier body 300.

In one embodiment, as shown in Figures 1 to 3, the shape of the recess 340 corresponds to the contour of the pivot 100, so as to accommodate the pivot 100 when it is not in use, ensuring that the pivot 100 does not protrude from the carrier body 300 in either the longitudinal or lateral directions, and that the recess 340 limits the pivot angle of the pivot 100.

In one embodiment, the shape of the recess may not correspond to the outline of the pivot 100, and its area may be larger than that of the pivot 100, thereby creating space to allow the pivot 100 to rotate completely.

The gear adjustment structure 400 may include: a first slot 170 formed on the vehicle body 300; a second slot 144 formed on the pivot portion 100; and a locking member 150 movably disposed between the first slot 170 and the second slot 144, and capable of simultaneously engaging with both slots 170 and 144, locking the pivot portion 100 in one pivot position relative to the vehicle body 300. The locking member 150 can be actuated to disengage from the second slot 144, allowing the pivot portion 100 to rotate freely relative to the vehicle body 300.

In one embodiment, the engaging member 150 can be actuated to disengage from the first slot 170, allowing the pivot 100 to rotate freely relative to the carrier body 300.

In one embodiment, the engaging member 150 can be actuated to disengage from both the first slot 170 and the second slot 144, allowing the pivot 100 to rotate freely relative to the carrier body 300.

It is understandable that the engaging member 150 only needs to be actuated to a position that allows the pivoting part 100 to rotate freely relative to the carrier body 300. In other words, as long as the engaging member 150 does not engage simultaneously with the first slot 170 and the second slot 144, the pivoting part 100 can rotate freely relative to the carrier body 300.

Referring to Figure 2, the carrier body 300 may include receiving slots 310. In one embodiment, each side of the carrier body 300 includes a receiving slot 310.

In one embodiment, the two pivots 100 are located on the outer sides of the two sides 330 of the carrier body 300. In this case, the receiving groove 310 is formed to be recessed from the outer sides of the two sides 330 of the carrier body 300, and the position of the receiving groove 310 corresponds to the position of the pivot 100.

In one embodiment, the two pivots 100 are located inside the two sides 330 of the carrier body 300. In this case, the receiving groove 310 is formed to be recessed from the inside of the two sides 330 of the carrier body 300, and the position of the receiving groove 310 corresponds to the position of the pivot 100.

The connecting shaft 180 can pass through the center of the receiving groove 310. The receiving groove 310 can be formed in a circular shape, and the dimensions of the outer contour of the receiving groove 310 correspond to the dimensions of the outer contours of the base 121 of the outer cover 120 and the base 141 of the inner cover 140.

Referring again to Figure 2, the first slot 170 includes an internal gear that can be formed in the receiving groove 310. The internal gear can contact the inner periphery and bottom wall of the receiving groove 310, but this disclosure is not limited thereto.

Referring to Figures 2 and 3, the engaging member 150 may include external teeth 151, a central hole 152, and a receiving groove 153.

In one embodiment, the engaging member 150 is a locking gear, but this disclosure is not limited thereto. The engaging member 150 is formed as an external gear such that it can mesh with a first retaining groove 170 having an internal gear. That is, the engaging member 150 can be received by the receiving groove 310.

In one embodiment, the engaging member 150 is a protrusion that can extend into the first slot 170 and the second slot 144.

To prevent the engaging member 150 from accidentally disengaging from the first slot 170 or the second slot 144, the thickness, size, and material of the engaging member 150 can be specifically set.

In one embodiment, the snap-fit element 150 is made of plastic-plastic composite (POM).

In one embodiment, the thickness of the snap-fit component 150 is 14 mm.

In one embodiment, when the engaging member 150 engages simultaneously with the first slot 170 and the second slot 144, the engagement thickness of the engaging member 150 with the first slot 170 and the second slot 144 is 7 mm respectively.

In one embodiment, the depth of each of the first slot 170 and the second slot 144 may be greater than or equal to the thickness of the engaging member 150, thereby ensuring that the engaging member 150 can be actuated to completely disengage from either the first slot 170 or the second slot 144.

Referring to Figures 26A to 28C, in one embodiment, the engaging member 150, which is formed as a locking gear, has multiple external teeth. The pivot 100 may have three pivot positions (i.e., the pivot 100 can be held at three pivot angles), namely a first pivot position (the retracted pivot position shown in Figure 26A), a second pivot position (the intermediate pivot position shown in Figure 27A), and a third pivot position (the maximum pivot position shown in Figure 28A). For example, the angle difference between the second pivot position (intermediate pivot position) and the third pivot position (maximum pivot position) can be less than the angle difference between the second pivot position (intermediate pivot position) and the first pivot position (receiving pivot position). Specifically, the angle difference between the first pivot position (receiving pivot position) and the third pivot position (maximum pivot position) can be 120°, and the angle difference between the second pivot position (intermediate pivot position) and the third pivot position (maximum pivot position) can be 20°, but this disclosure is not limited to this. The first pivot position (reservation pivot position) is used for storing the pivot part 100, wherein the pivot part 100 can pivot into the recess 340 (see Figure 26A) for easy storage, and can be stored when the pivot part 100 is not in use. The three pivot positions of the pivot part 100 can be achieved by adjusting the shape of the second slot 144 of the inner cover 140, and/or by adjusting the shape of the first slot 170, but this disclosure is not limited thereto.

To facilitate user identification and confirmation of whether the pivot unit 100 has reached a designated pivot position, a gear position indicator 100A may be provided on the pivot unit 100 (see Figures 60 to 62, wherein the gear position indicator 100A is located on the outer periphery of the pivot unit 100). At least two gear position indicators 300A may be provided on the carrier body 300 near the pivot unit 100 (see Figures 60 to 62, wherein there are three gear position indicators 300A: 1, 2, and 3). When the pivot unit 100 pivots to a designated pivot position, the gear position indicator 100A will align with one of the gear position indicators 300A, thereby assisting the user in adjusting the gear position of the pivot unit 100.

In order to enable the pivot unit 100 to be adjusted and locked between three pivot positions, in the embodiments shown in Figures 26A to 31, taking a scheme in which the engaging member 150 can be actuated to disengage from and engage with the second slot 144 as an example, this disclosure provides the following configuration for the engaging member 150, the first slot 170, and the second slot 144.

As shown in Figure 30, the two consecutive external teeth 151 of the engaging member 150, which are formed as external gears, are provided with an external tooth connection portion 155 between them. For ease of description, the two consecutive external teeth 151 with the external tooth connection portion 155 between them are defined below as gear-adjusting external teeth 151A. The external tooth connection portion 155 can be integrally formed with the two gear-adjusting external teeth 151A of the engaging member 150, or it can be formed separately and then joined together. In addition, the external tooth connection portion 155 can partially or completely fill the space between the two gear-adjusting external teeth 151A.

As shown in Figure 29, the internal gear of the first slot 170 has multiple internal teeth, which can be referred to as the first slot internal teeth 172. In the configuration where the engaging member 150 can be actuated to disengage from and engage with the second slot 144 shown in Figure 31, as shown in Figure 29, the internal gear of the first slot 170 has a first missing tooth portion 171, which lacks one first slot internal tooth 172, allowing it to accommodate two consecutive external teeth 151 of the engaging member 150. Thus, the first missing tooth portion 171 can accommodate the two-position adjusting external teeth 151A of the engaging member 150. In other words, the two-position adjusting external teeth 151A of the engaging member 150 can only engage with the first missing tooth portion 171 of the first slot 170.

The internal gear of the second slot 144 has multiple internal teeth, which can be referred to as the second slot internal gear 144C. The second slot internal gear 144C of the second slot 144 and the first slot internal gear 172 of the first slot 170 correspond in shape and size to the external gear 151 of the engaging member 150.

As shown in Figure 31, the internal gear of the second slot 144 has a second toothed portion 144A and a third toothed portion 144B that are spaced apart from each other by at least one second slot internal tooth 144C (Figure 31 shows three second slot internal teeth 144C). Given a fixed number of second slot internal teeth 144C, the number of second slot internal teeth 144C located between the second toothed portion 144A and the third toothed portion 144B will affect the angle difference between the first pivot position (receiving pivot position) and the second pivot position (intermediate pivot position). A larger number of teeth results in a larger angle difference, and a smaller number results in a smaller angle difference.

In the embodiment shown in FIG31, the second missing tooth portion 144A lacks two consecutive second slot internal teeth 144C, so that it can accommodate three consecutive external teeth 151 of the latching member 150. The third missing tooth portion 144B lacks one second slot internal tooth 144C, so that it can accommodate two consecutive external teeth 151 of the latching member 150. Therefore, the third missing tooth portion 144B, lacking one second slot internal tooth 144C, can accommodate the two-position adjusting external teeth 151A of the engaging member 150. The second missing tooth portion 144A, lacking two consecutive second slot internal teeth 144C, can accommodate the two-position adjusting external teeth 151A of the engaging member 150, as well as an adjacent external tooth 151B1 (on one side) or 151B2 (on the other side). In other words, the two-position adjusting external teeth 151A of the engaging member 150 can only engage with either the second missing tooth portion 144A or the third missing tooth portion 144B.

Based on the above configuration, the engaging member 150 is always engaged with the first slot 170, so the two adjustable external teeth 151A of the engaging member 150 are accommodated in the first tooth portion 171 of the first slot 170. When the engaging member 150 engages with the second slot 144, since the two adjustable external teeth 151A of the engaging member 150 can only be accommodated in the second tooth portion 144A or the third tooth portion 144B of the second slot 144, the second slot 144 and the engaging member 150 can engage in three pivot positions. The second tooth portion 144A provides two pivot positions (i.e., the second pivot position and the third pivot position, that is, the intermediate pivot position and the maximum pivot position), and the third tooth portion 144B provides one pivot position (i.e., the first pivot position, that is, the retractable pivot position). This will be described in detail below. Therefore, the pivot section 100 forming the second slot 144 can only be adjusted to and locked in three pivot positions.

Of course, the above-described arrangement of the card holder 150, the first card slot 170, and the second card slot 144 is merely an example, and this disclosure is not limited thereto.

The external gear of the engaging member 150 can have two or more adjustable external teeth 151A. Correspondingly, the first notch portion 171 of the first slot 170 can lack one or more consecutive first slot internal teeth 172, the second notch portion 144A of the second slot 144 can lack two or more consecutive second slot internal teeth 144C, and the third notch portion 144B of the second slot 144 can lack one or more consecutive second slot internal teeth 144C. Thus, the second notch portion 144A can provide two or more pivot positions, and the third notch portion 144B provides one pivot position, allowing the second slot 144 and the engaging member 150 to engage in three or more pivot positions.

Specifically, for example, when the external gear of the locking member 150 has N+1 adjustable external gears 151A, correspondingly, the first missing tooth portion 171 of the first slot 170 may be missing N consecutive first slot internal teeth 172 (when N is 1, the first missing tooth portion 171 is missing one first slot internal tooth 172), the second missing tooth portion 144A of the second slot 144 may be missing N+M consecutive second slot internal teeth 144C, and the third missing tooth portion 144B of the second slot 144 may be missing N consecutive second slot internal teeth 144C (when N is 1, the third missing tooth portion 144B is missing one second slot internal tooth 144C), where N and M are integers greater than zero. Therefore, when the engaging member 150 engages with the second slot 144, and the second notch 144A accommodates the N+1 adjustable external teeth 151A of the engaging member 150 and the M adjacent external teeth 151, the engaging member 150 can engage with the second slot 144 in M+1 different pivot positions, allowing the pivot part 100 to be positioned in M+1 different pivot positions. Adding the pivot position provided by the third notch 144B, the second slot 144 and the engaging member 150 can engage in M+2 different pivot positions.

Figures 26A to 28C illustrate one embodiment of the three pivot positions of the pivot unit 100, wherein N and M are both 1, i.e., the external gear of the engaging member 150 has two adjustable external teeth 151A, the first toothed portion 171 of the first slot 170 lacks one first slot internal tooth 172, the second toothed portion 144A of the second slot 144 lacks two consecutive second slot internal teeth 144C, and the third toothed portion 144B of the second slot 144 lacks one second slot internal tooth 144C.

As shown in Figures 26A to 26C, the second slot 144 engages with the engaging member 150 in the first pivot position, such that the pivot portion 100 is located in the first pivot position (i.e., the retracted pivot position). This first pivot position can be configured such that at least a portion of the pivot portion 100 is located within the recess 340 (see Figure 26A) of the carrier body 300, in the retracted position.

As shown in Figure 26C, when the pivot 100 is in the first pivot position, the two-position adjusting external teeth 151A of the engaging member 150 are accommodated in the third notch 144B of the second slot 144, which can accommodate two consecutive external teeth 151.

As shown in Figures 27A to 28C, the second slot 144 engages with the engaging member 150 in the second and third pivot positions, respectively, so that the pivot part 100 is positioned in the second pivot position (i.e., the intermediate pivot position) and the third pivot position (the maximum pivot position). These second and third pivot positions can be configured such that the pivot part 100 is in two working positions, allowing the anchoring assembly of the pivot part 100 to be connected to the vehicle seat at two angles.

As shown in Figure 28C, when the pivot 100 is in the third pivot position, the two adjustable external teeth 151A of the engaging member 150 and an adjacent external tooth 151B1 located to one side are accommodated in the second notch 144A of the second slot 144, which can accommodate three consecutive external teeth 151.

As shown in Figure 27C, when the pivot 100 is in the second pivot position, the two adjustable external teeth 151A of the engaging member 150 and another adjacent external tooth 151B2 on its opposite side are accommodated in the second toothed portion 144A of the second slot 144, which can accommodate three consecutive external teeth 151.

This allows the pivot 100 to pivot and lock only between three pivot positions. The first position can be used to store the pivot 100 in the vehicle 1. By setting the angles between the three pivot positions, for example, as mentioned earlier, the angle difference between the second and third pivot positions is smaller than the angle difference between the second and first pivot positions. The second and third pivot positions ensure that the vehicle 1 is connected to the vehicle seat at a suitable angle via the anchoring assembly, thereby preventing accidents such as the vehicle 1 tipping over.

Of course, this disclosure is not limited to this.

In another embodiment, the engaging member 150 can be actuated to disengage from the first slot 170. Therefore, the configuration of the engaging member 150, the first slot 170, and the second slot 144 needs to be modified accordingly. Specifically, the internal gear of the second slot 144 has only a first missing tooth portion, allowing it to accommodate the N+1 adjustable external teeth 151A of the engagement piece 150; the internal gear of the first slot 170 has a second and a third missing tooth portion spaced apart by at least one tooth, such that the third missing tooth portion lacking N consecutive internal teeth can accommodate the N+1 adjustable external teeth 151A of the engagement piece 150, and the second missing tooth portion lacking N+M consecutive internal teeth can accommodate the N+1 adjustable external teeth 151A of the engagement piece 150 and M adjacent external teeth, where N and M are integers greater than zero. Therefore, the first slot 170 can engage with the engagement piece 150 in M+1 different pivot positions. Therefore, the pivot 100 forming the second slot 144 can also be adjusted to and locked at the M+1 pivot position.

In other embodiments, the external gear of the engaging member 150 may not have an external gear connection portion 155, that is, the gear adjustment external gear 151A is not provided. Therefore, the external gear of the engaging member 150 can engage with the internal gears of the first slot 170 and the second slot 144 in multiple pivot positions, thus the pivoting part 100 can be adjusted and locked between multiple pivot positions.

For example, in the embodiment shown in Figure 30, the engaging member 150 may have 18 external teeth 151, and the first slot 170 and the second slot 144 have corresponding internal teeth. When the external tooth connection portion 155 is not provided on the external gear of the engaging member 150, the angular difference in the pivot position of the pivot portion 100 for each tooth rotation is 20°.

In other embodiments, the engaging member 150 may have 12 external teeth 151, and the first slot 170 and the second slot 144 similarly have corresponding internal teeth. When the external tooth connection portion 155 is not provided on the external gear of the engaging member 150, the angular difference in the pivot position of the pivot portion 100 for each tooth rotation is 30°.

It should be understood that the locking component 150 can have other numbers of teeth, such as 10, 11, 13, 14, 15, 16, etc. However, it should be understood that the more teeth the locking component 150 has, the weaker the strength and force that each tooth can withstand, the weaker the load-bearing capacity of the pivot 100, and the higher the manufacturing cost. Therefore, the number of teeth in the locking component 150 should be set according to actual needs.

In one embodiment, the gear height is 1.025 mm.

The connecting shaft 180 can pass through the center hole 152 of the engaging member 150.

In one embodiment, the receiving groove 153 is formed on the outer side of the engaging member 150 (the side away from the carrier body 300).

In one embodiment, a receiving groove 153 is formed on the inner side of the engaging member 150 (on the side closer to the carrier body 300).

Both the center hole 152 and the receiving groove 153 are centrally formed on the engaging member 150. The center hole 152 and the receiving groove 153 may be formed as concentric circles, but this disclosure is not limited thereto.

The gear shifting mechanism 400 may also include a reset element 160.

In one embodiment, the reset element 160 is a coil spring.

In one embodiment, the reset element 160 is an elastic body.

In one embodiment, the repositioning member 160 is a magnet. In this disclosure, a magnet can refer to a material that can provide magnetic force. Correspondingly, the engaging member 150 can be a magnet or an ferrous component, thus being actuated by the repositioning member formed as a magnet. The repositioning member 160 formed as a magnet can be fixed to the bottom wall of the first slot 170.

In one embodiment, a resetting member 160 is disposed between the first slot 170 and the engaging member 150, and abuts against the first slot 170 and the engaging member 150 to provide a restoring force tending to engage the engaging member 150 with the second slot 144 (as shown in FIG. 2). In this embodiment, the engaging member 150 can be actuated to disengage from the second slot 144.

In one embodiment, a repositioning member 160 is disposed between the inner cover 140 and the engaging member 150, and abuts against the inner cover 140 and the engaging member 150 to provide a restoring force (not shown) tending to engage the engaging member 150 with the first retaining groove 170. In this embodiment, the engaging member 150 can be actuated to disengage from the first retaining groove 170.

One end of the repositioning member 160 may be located within the receiving groove 153 of the engaging member 150, and the other end of the repositioning member 160 may be located within the receiving groove 310 of the carrier body 300 or within a receiving groove (not shown) on the inner cover 140.

As shown in Figure 3, the second slot 144 includes an internal gear. The second slot 144 may be formed on the inner side of the inner cover 140 (the side facing the carrier body 300).

The thickness of the engaging component 150 can be set to allow it to engage simultaneously with the first slot 170 and the second slot 144.

Referring to Figures 2 and 3, the gear adjustment structure 400 may further include a drive unit 110. The drive unit 110 is movably disposed in the pivot unit 100 and can be actuated to cause the engaging member 150 to disengage from the first slot 170 or the second slot 144.

The first implementation method of the drive unit

In one embodiment, the drive unit 110 is configured as a button.

In one embodiment, the drive unit 110 is configured as a pulling member, such as a pull ring, hook, grip, etc.

In one embodiment, the drive unit 110 may be at least partially disposed within the receiving groove 123 of the outer cover 120. The outer side of the drive unit 110 (the side away from the carrier body 300) may be exposed, thereby allowing it to be touched by a part of a person (e.g., a hand).

The drive unit 110 may include latching portions 111. The latching portion 111 may be formed in the shape of a straight rod, extending inward from the main body of the drive unit 110. The free end of the latching portion 111 may be formed in the shape of a hook. The drive unit 110 may include four latching portions 111 corresponding to the four holes 124 of the outer cover 120 and the four holes 134 of the main body 130, but this disclosure is not limited thereto.

Referring to Figures 4 to 6, the latching part 111 can pass through the hole 124 in the outer cover 120, the hole 134 in the body part 130, and the center hole 143 in the inner cover 140 to abut against the engaging part 150.

The hole 134 of the main body 130 is not precisely aligned with the free end of the hook-shaped part 111. Thus, when the hook-shaped part 111 passes through the hole 134 of the main body 130, it undergoes elastic deformation, and after passing through the hole 134, the surrounding portion of the hole 134 prevents the free end of the hook-shaped part 111 from passing through the hole 134 again. Therefore, the hook-shaped part 111 prevents the drive unit 110 from separating from the pivot unit 100.

When the drive unit 110 is not actuated, the engaging member 150 engages simultaneously with the first slot 170 and the second slot 144, locking the pivot unit 100 in one of its pivot positions relative to the carrier body 300 and preventing it from pivoting around the connecting shaft 180.

When the drive unit 110 is not actuated, the outer surface of the drive unit 110 is flush with the outer surface of the base 121 of the outer cover 120, thus providing better appearance and ease of operation.

In one embodiment, the outer surface of the base 121 of the outer cover 120 may not protrude from the outer surface of the side 330 of the carrier body 300, so that the carrier 1 has a flat appearance.

In one embodiment, the drive unit 110 can be actuated in a direction perpendicular to the pivot plane of the pivot unit 100.

In one embodiment, when the drive unit 110 is actuated (e.g., by pressing the drive unit 110 in the direction toward the carrier body 300), the latching portion 111 of the drive unit 110 actuates the engaging member 150 to move in a direction disengaging from the second slot 144. This process requires overcoming the restoring force of the resetting member 160. When the engaging member 150 is fully disengaged from the second slot 144, the pivot unit 100 can pivot about the connecting shaft 180. When the pivot unit 100 pivots to the desired angle, the actuation of the drive unit 110 is released, causing the engaging member 150 to engage again simultaneously with the first slot 170 and the second slot 144, thus preventing undesirable pivoting of the pivot unit 100.

In one embodiment, when the drive unit 110 is actuated (e.g., pulled out in a direction away from the carrier body 300), since one end of the drive unit 110 is connected to the engaging member 150, the drive unit 110 can drive the engaging member 150 in a direction disengaging from the first slot 170. This process requires overcoming the restoring force of the resetting member 160. When the engaging member 150 is completely disengaged from the first slot 170, the pivot unit 100 can rotate about the connecting shaft 180. When the pivot 100 rotates to the desired angle, the actuation of the drive unit 110 is released, causing the engaging member 150 to engage simultaneously with the first slot 170 and the second slot 144, thus preventing undesirable rotation of the pivot 100.

In one embodiment, the drive units 110 of the two pivot units 100 on both sides of the carrier body 300 are simultaneously actuated to unlock both pivot units 100, and the two pivot units 100 rotate synchronously.

In one embodiment, the connecting shaft 180 may be omitted, allowing the two pivots 100 to pivot independently after unlocking.

In one embodiment, the drive unit 110 may be configured as a knob, lever, or handle.

In one embodiment, the drive unit 110 may be formed on the outer periphery of the base 121 of the outer cover 120 and/or the base 141 of the inner cover 140, and the drive unit 110 may be actuated radially (the direction of movement points toward the connecting axis of the pivot 100). In this embodiment, the pivot 100 may protrude laterally from the side 330 of the carrier body 300. The pivot 100 may include a wedge-shaped member (not shown) that engages with the drive unit 110 to convert the radial motion of the drive unit 110 into the axial motion of the wedge-shaped member. This allows the wedge-shaped member to actuate the engaging member 150 and disengage from the first slot 170 or the second slot 144 when the drive unit 110 is pressed. This embodiment makes unlocking the rotation of the pivot 100 more convenient, requiring only one hand to simultaneously press the drive unit 110 and rotate the pivot 100.

The second implementation method of the drive unit

Figures 46 to 59 illustrate a second embodiment of the drive unit 110' according to the present disclosure. The main difference between this second embodiment and the first embodiment described above with reference to Figures 2 to 6 is that the drive unit 110' in the second embodiment includes two components: a drive unit pivot 112 and a drive unit pusher 113. Through the interaction of these two components, the user only needs to apply an external force in the same direction to the drive unit pivot 112 of the drive unit 110' to not only unlock the pivot 100 but also to rotate it.

In one embodiment, as shown in FIG51, the drive unit pivot 112 of the drive unit 110' is rotatably disposed in the pivot unit 100, and the drive unit pusher 113 is movably disposed between the drive unit pivot 112 and the engaging member 150. Furthermore, the drive unit pivot 112 is configured such that, under the action of an external force, the drive unit pusher 113 can drive the engaging member 150 to disengage from the first slot 170 or the second slot 144.

In other words, through the interaction between the drive unit pivot 112 and the drive unit pusher 113, the pivoting motion of the drive unit pivot 112 can be converted into the movement of the engaging member 150.

The drive unit pivot 112 is configured such that its pivot plane is the same as or parallel to the pivot plane of the pivot unit 100, so that an external force in the same direction that drives the drive unit pivot 112 to pivot can also drive the pivot unit 100 to pivot, thereby greatly facilitating user operation.

In this document, "rotation plane" refers to the plane occupied by a component during rotation. For example, the rotation plane of the drive unit pivot 112 refers to the plane occupied by the drive unit pivot 112 during rotation, and the rotation plane of the pivot unit 100 refers to the plane occupied by the pivot unit 100 during rotation.

The drive unit pivot 112 will now be described in detail.

In the embodiments shown in Figures 50, 52, and 53, the drive unit pivot 112 includes a pivot push section 112A, on which a push slope 112A1 is provided. The push slope 112A1 is configured to be inclined to the moving direction of the drive unit push member 113. Specifically, the distance between the push slope 112A1 and the side of the pivot push section 112A to which it is located gradually increases or decreases from one side of the push slope 112A1 along the pivot direction toward the other side, causing the push slope 112A1 to be inclined to the side of the pivot push section 112A to which it is located. Inclined to the direction of movement of the drive unit pusher 113, this structure allows the pushing ramp 112A1 to push the drive unit pusher 113 against it to move in a direction perpendicular to the rotation direction when the drive unit pivot 112 rotates, thereby driving the engaging member 150.

In the embodiments shown in Figures 51 to 54, the pivot pressing section 112A is sheet-like or plate-like, and a pressing ramp 112A1 is disposed on the side surface of the pivot pressing section 112A. In this case, as shown in Figures 52 and 53, because the pivot pressing section 112A is relatively thin, when the pressing ramp 112A1 is formed on one side surface of the pivot pressing section 112A, a ramp shape corresponding to the pressing ramp 112A1 will also be generated on the other side surface.

However, this disclosure is not limited to this; the pivoting member pressing section 112A can be block-shaped or columnar, as long as it can pivot and a pressing ramp 112A1 can be provided on the side facing the driving part pusher 113.

The pivot member pressing section 112A has a pivot member pivot portion 112A2, around which the drive unit pivot member 112 pivots. In the embodiment shown in Figures 52 and 53, the pivot member pivot portion 112A2 is a pivot hole. However, it should be understood that the pivot member pivot portion 112A2 can also be a pivot shaft.

To facilitate the user's application of external force to the drive unit pivot 112, in the embodiments shown in Figures 50 and 51, the drive unit pivot 112 may also include a pivot pressing section 112B. The pivot pressing section 112B extends from the pivot pushing section 112A in a direction away from the pivot pivot portion 112A2, for user operation. The presence of the pivot pressing section 112B increases the distance between the furthest point of force application of the drive unit pivot 112 and the pivot pivot portion 112A2, thus generating a larger torque for pivoting the drive unit pivot 112 from the same external force applied to the furthest point of force application, making user operation easier.

As shown in Figure 54, the pivot pressing section 112B may be provided with a pressing flange 112B1 for applying external force. The pressing flange 112B1 is generally located at the furthest point of force application of the drive pivot 112, so that the user only needs to apply a small amount of external force to the pivot pressing section 112B to actuate the drive pivot 112. Of course, the pressing flange 112B1 can also be located at other locations besides the furthest point of force application of the drive pivot 112.

The pivot pressing section 112B can be integrated with the pivot pushing section 112A. In this case, the pivot pressing section 112B can be considered as part of the pivot pushing section 112A. Alternatively, the drive unit pivot 112 may not include a separate pivot pressing section 112B.

The pivot pressing section 112B can also be formed as two separate components with the pivot pushing section 112A. In this case, the pivot pressing section 112B and the pivot pushing section 112A can be formed separately and then assembled together.

In the embodiments shown in Figures 53 and 54, the pivot member pressing section 112A has two fixing protrusions 112A3, and the pivot member pressing section 112B has a fixing recess 112B2 corresponding to the fixing protrusions 112A3 of the pivot member pressing section 112A. The pivot member pressing section 112A and the pivot member pressing section 112B are connected together through the engagement of the fixing protrusions 112A3 and the fixing recess 112B2.

It should be understood that this disclosure is not limited thereto. The fixing protrusion 112A3 may be provided on the pivot member pressing section 112B, and the fixing recess 112B2 may be provided on the pivot member pushing section 112A. Alternatively, the fixing protrusion 112A3 and the fixing recess 112B2 may be provided as needed, either one or more. Alternatively, the pivot member pushing section 112A and the pivot member pressing section 112B may be connected together by means of interlocking, threaded connection, or rivet connection.

As previously described, the pivot 100 includes an outer cover 120, a main body 130, and an inner cover 140, as shown in Figure 51. The outer cover 120 and the inner cover 140 together enclose a space, within which the main body 130 is located.

In the embodiments shown in Figures 51, 55 to 59, the circumferential wall of the base 121 of the outer cover 120 may be provided with an outer cover slot 121A through which the drive unit pivot 112 passes. The outer cover slot 121A extends circumferentially along the base 121 of the outer cover 120, thereby exposing the drive unit pivot 112 to the pivot part 100 for user convenience.

Of course, this disclosure is not limited to this. The drive unit pivot 112 can be pivotally disposed on the outer side of the end wall of the base 121 of the outer cover 120. In this case, the end wall of the base 121 needs to be provided with a through hole so that the drive unit pusher 113 located inside the base 121 passes through the through hole and contacts the drive unit pivot 112.

Additionally, as shown in Figures 55 and 57, the inner end wall of the outer cover 120 is provided with an outer cover pivot portion 125, which cooperates with the pivot portion 112A2 of the drive unit pivot member 112, thereby allowing the drive unit pivot member 112 to rotate. In the embodiment shown in Figures 55 and 57, the outer cover pivot portion 125 is a pivot shaft. However, it should be understood that when the pivot portion 112A2 that cooperates with it is a pivot shaft, the outer cover pivot portion 125 can also be a pivot hole.

Furthermore, as shown in Figure 55, a pivot stop 126 may be provided at the end of the outer cover pivot 125 to prevent the drive pivot 112 from disengaging from the outer cover pivot 125. The pivot stop 126 may be, for example, a screw threaded to the end of the outer cover pivot 125, or a pin laterally inserted into the end of the outer cover pivot 125.

Next, the drive unit actuator 113 will be described in detail.

The drive unit pusher 113 is disposed between the drive unit pivot 112 and the engaging member 150. On one hand, it is moved by the push of the drive unit pivot 112; on the other hand, it drives the engaging member 150 to disengage from the first slot 170 or the second slot 144.

To improve the effect of the pressing ramp 112A1 on the pivot pressing section 112A on the driving part pusher 113, as shown in Figure 51, the driving part pusher 113 may be provided with a pusher end 113A, which abuts against the pressing ramp 112A1.

To improve the effect of the drive unit pusher 113 driving the engaging member 150, the drive unit pusher 113 may be provided with at least one pusher rod 113B. The pusher rod 113B may be in the shape of a straight rod, abutting against the engaging member 150, so that once the pusher rod 113B moves, it will drive the engaging member 150.

In the embodiments shown in Figures 51 and 55, the pusher rod 113B extends parallel to the direction of movement of the engaging member 150 or parallel to the connecting shaft 180, thereby better driving the engaging member 150. Of course, it should be understood that the pusher rod 113B may extend inclined to the direction of movement of the engaging member 150.

As shown in Figures 51, 56, and 59, the push rod 113B of the drive unit pusher 113 can pass through the body 130 and the inner cover 140 and abut against the engaging member 150.

To facilitate the passage of the push rod 113B through the body component 130, the body component 130 is provided with a hole 134 corresponding to the push rod 113B (see Figure 51).

To prevent the push rod 113B from disengaging from the hole 134 of the body component 130 and causing accidental separation of the drive unit push rod 113 from the body component 130, in the embodiments shown in Figures 51, 56, and 59, a push rod hook 113B1 may be provided at the end of the push rod 113B that abuts against the engaging member 150. The push rod hook 113B1 is configured such that after passing through the hole 134 of the body component 130, it can be blocked by the hole wall of the hole 134 and cannot disengage from the hole 134.

Additionally, the push rod catch 113B1 can also limit the travel distance of the push rod 113B.

In one embodiment, the hole 134 of the body component 130 is not precisely aligned with the push hook 113B1 of the push member push rod 113B. Thus, when the push hook 113B1 passes through the hole 134 of the body component 130, the push member push rod 113B undergoes elastic deformation; after the push hook 113B1 passes through the hole 134 of the body component 130, the push member push rod 113B elastically returns to its original position, and the hole wall of the hole 134 of the body component 130 will block the push hook 113B1, preventing it from exiting the hole 134 of the body component 130. Therefore, the push hook 113B1 can prevent the drive push member 113 from accidentally separating from the body component 130.

When it is necessary to disassemble the drive unit pusher 113 from the main body 130, the user only needs to apply force to the push rod hook 113B1, forcing the push rod 113B to undergo elastic deformation. When the push rod hook 113B1 aligns with the hole 134 in the main body 130, the push rod hook 113B1 can disengage from the hole 134, thereby separating the drive unit pusher 113 from the main body 130.

The working process of the drive unit 110', including the drive unit pivot 112 and the drive unit pusher 113, is then described in detail.

When the drive unit 110' is not actuated, the engaging member 150 engages simultaneously with the first slot 170 and the second slot 144, as shown in FIG. 5, so that the pivot unit 100 is locked in one of the pivot positions relative to the carrier body 300 (e.g., the storage position shown in FIGS. 46 to 49) and cannot pivot around the connecting shaft 180.

When it is necessary to rotate the pivot 100 from the storage position or a certain working position to another working position in the third rotation direction R3, the user applies an external force to the drive pivot 112 to make it rotate, and the drive pivot 112 rotates in the third rotation direction R3 (see Figures 46 to 49). Therefore, referring to Figures 48, 51, and 53, during the rotation of the drive unit pivot 112 towards the third rotation direction R3, the pushing slope 112A1 of its pivot push section 112A pushes the drive unit pusher 113, causing the drive unit pusher 113 to move in a direction perpendicular to the rotation direction. This, in turn, drives the engaging member 150 to move in the direction of disengagement from the second slot 144.

When the engaging member 150 is completely disengaged from the second slot 144, the pivot 100 unlocks and can pivot around the connecting shaft 180. Then, under the same external force applied by the user, the pivot 100 pivots in the third rotation direction R3 (see Figures 46 to 49) until it reaches the desired pivot angle (i.e., another working position).

Subsequently, the user can release the actuation of the drive unit 110', that is, the user no longer applies external force to the drive unit pivot 112. The engaging member 150, under the action of the resetting member 160 (see Figures 2, 3, 5, 6, and 8), simultaneously engages again with the first slot 170 and the second slot 144, thereby locking the pivot 100 at that pivot angle. At the same time, the drive unit pivot 112 will also pivot in the fourth rotation direction R4 (see Figures 46 to 49), for example, due to the force of the resetting member 160, thus returning to its initial position (described below).

Therefore, when the second embodiment 110' of the drive unit according to this disclosure is adopted, the user only needs to apply an external force in the same direction to the drive unit pivot 112 of the drive unit 110', for example, with their thumb. This not only causes the drive unit pivot 112 to pivot and unlock the pivot unit 100, but also causes the pivot unit 100 to pivot in the third rotation direction R3, greatly facilitating the user's operation.

When it is necessary to rotate the pivot 100 from one working position to another working position or storage position in the fourth rotation direction R4, the user applies an external force to the drive pivot 112 to rotate it. The drive pivot 112 rotates in the third rotation direction R3 until the pivot 100 is unlocked and can rotate around the connecting shaft 180 degrees. Subsequently, the user applies an external force in the opposite direction to the pivot 100, causing the pivot 100 to rotate in the fourth rotation direction R4 until the pivot 100 reaches the required pivot angle (i.e., another working position or storage position). In this process, the user can use their thumb to press the drive pivot 112 to rotate it in the third rotation direction R3 to unlock the pivot 100, and then use the other fingers to rotate the pivot 100 in the fourth rotation direction R4. This allows the user to rotate the pivot 100 with just one hand, simplifying the operation.

In another embodiment, the drive unit pivot 112 may be configured to unlock the pivot 100 by pivoting in the fourth rotation direction R4, rather than in the third rotation direction R3. In this embodiment, the inclination direction of the pressing ramp 112A1 of the pivot member pressing section 112A is opposite to that of the pressing ramp 112A1 in the aforementioned embodiment, thereby allowing the pressing ramp 112A1 of the pivot member pressing section 112A to push the drive unit pusher 113 to move in a direction perpendicular to the rotation direction during the pivoting process of the drive unit pivot 112 in the fourth rotation direction R4.

Correspondingly, a pull flange (not shown) may be provided on the drive unit pivot 112 to allow the user to pull the drive unit pivot 112 to pivot in the fourth rotation direction R4.

In another embodiment described above, the user only needs to apply an external force in the same direction to the drive unit pivot 112 of the drive unit 110'. This not only causes the drive unit pivot 112 to pivot and unlock the pivot unit 100, but also allows the pivot unit 100 to pivot in the fourth rotation direction R4, greatly facilitating the user's operation.

After the pivot 100 reaches the desired pivot angle, the user no longer applies external force to the drive pivot 112. At this point, under the restoring force of the aforementioned reset member 160, the drive pivot 112 will return to its initial position.

Specifically, when the user no longer applies external force to the drive unit pivot 112, the restoring force of the reset member 160 will force the engaging member 150 to move toward and engage with the second slot 144, thereby locking the pivot 100 at the pivot angle. During this process, the engaging member 150 will drive the drive unit pusher 113, which is abutting against it, to move toward the drive unit pivot 112. Therefore, the drive unit pusher 113 further pushes the push slope 112A1 of the pivot pusher section 112A, thereby causing the pivot pusher section 112A, i.e., the drive unit pivot 112, to pivot in the fourth rotation direction R4 (see Figures 46 to 49) and return to its initial position.

In another embodiment, the drive unit 110' may be provided with a drive unit reset member (not shown). When the drive unit pivot 112 is not subjected to external force, the drive unit reset member will drive the drive unit pivot 112 back to its initial position. The drive unit reset member may be a torsion spring surrounding the pivot pivot 112A2 of the drive unit pivot 112, or it may be other elastic bodies such as springs or tension springs that can apply elastic force to the drive unit pivot 112.

In the case where the carrier 1 has two pivots 100, the two pivots 100 are respectively coupled to the two ends of the connecting shaft 180. A drive unit 110' (i.e., a drive unit pivot 112) can be provided at each of the two pivots 100, as shown in Figures 46 to 49, 55, 56, 58, and 59.

The third implementation method of the drive unit

Figures 60 to 65 illustrate a third embodiment 110” of the drive unit according to the present disclosure, which includes a drive unit pivot button 114, a drive unit rotary disk 115, and a drive unit moving member 116. The third embodiment 110” of the drive unit differs from the second embodiment 110’ of the drive unit described above with reference to Figures 46 to 59 mainly in that the drive unit pivot button 114 and drive unit rotary disk 115 in the third embodiment of the drive unit 110”, which can rotate together, replace the drive unit pivot member in the second embodiment, and the drive unit moving member 116 in the third embodiment of the drive unit 110” replaces the drive unit pusher in the second embodiment. In the third embodiment of the drive unit 110", through the interaction of the drive unit rotary disk 115 and the drive unit moving member 116, the user only needs to apply an external force in the same direction to the drive unit pivot button 114 to not only unlock the pivot unit 100, but also to pivot the pivot unit 100.

In one embodiment, as shown in Figures 64 and 65, the drive unit pivot button 114 and drive unit rotary disk 115 in the drive unit 110” are rotatably disposed in the pivot unit 100, and the drive unit moving member 116 is movably disposed between the drive unit rotary disk 115 and the engaging member 150 (not shown). Furthermore, the drive unit pivot button 114 and drive unit rotary disk 115 are rotatably disposed between the drive unit rotary disk 115 and the engaging member 150 (not shown). The pivot button 114 is configured such that, under the action of external force, it can drive the engaging member 150 (not shown) to disengage from the first slot 170 (not shown) on the carrier body 300 or the second slot 144 (see Figures 64 and 65) on the pivot 100 via the drive unit rotary plate 115 and the drive unit moving member 116.

In other words, through the interaction between the drive unit rotary disk 115 and the drive unit moving member 116, the rotation of the drive unit pivot button 114 can be converted into the movement of the engaging member 150.

The drive unit pivot button 114 is configured such that its rotation plane is the same as or parallel to the pivot plane of the pivot unit 100. This ensures that an external force in the same direction as the drive unit pivot button 114 can also drive the pivot unit 100 to rotate, thereby greatly facilitating user operation.

In this document, the term "rotation plane" has a similar meaning to the aforementioned "pivot plane," referring to the plane occupied by a component during rotation. For example, the rotation plane of the drive unit pivot button 114 refers to the plane occupied by the drive unit pivot button 114 during rotation.

The following is a detailed description of the drive unit pivot button 114 and the drive unit rotary table 115.

The drive unit pivot button 114 is provided with a button rotation portion 114B, allowing the drive unit pivot button 114 to rotate around the button rotation portion 114B. In the embodiment shown in Figures 64 and 65, the button rotation portion 114B is a rotating hole. However, it should be understood that the button rotation portion 114B can also be a rotating shaft.

To facilitate the user's application of external force to the drive unit pivot button 114, in the embodiments shown in Figures 64 and 65, the drive unit pivot button 114 may also be provided with a button pressing portion 114A for applying external force. The button pressing portion 114A is generally located at the furthest point of force application on the drive unit pivot button 114, away from the button rotating part 114B, so that the user only needs to apply a small amount of external force to the button pressing portion 114A to actuate the drive unit pivot button 114. Of course, the button pressing portion 114A may also be located at other locations besides the furthest point of force application on the drive unit pivot button 114.

The drive unit rotating disk 115 is provided with a rotating disk pivot 115B, allowing the drive unit rotating disk 115 to rotate around the rotating disk pivot 115B. In the embodiment shown in Figures 64 and 65, the rotating disk pivot 115B is a rotating hole. However, it should be understood that the rotating disk pivot 115B can also be a rotating shaft.

The drive unit's rotating disk 115 can be configured as a disc as shown in Figures 64 and 65, or it can be configured as a polygon or other suitable shape.

In order for the drive unit pivot button 114 and the drive unit rotating disk 115 to rotate together, the button rotating part 114B of the drive unit pivot button 114 and the rotating disk pivot part 115B of the drive unit rotating disk 115 should be configured to correspond to each other, so that the rotation axis of the drive unit pivot button 114 overlaps with the rotation axis of the drive unit rotating disk 115, thereby achieving rotation of the drive unit pivot button 114 and the drive unit rotating disk 115 around the same rotation axis.

In one embodiment, the drive unit pivot button 114 and the drive unit rotary disk 115 can be connected together. For example, the drive unit pivot button 114 has a button connection portion 114C, and the drive unit rotary disk 115 has a rotary disk connection portion 115C; the button connection portion 114C and the rotary disk connection portion 115C are connected via a rotary connector 117.

In the embodiments shown in Figures 64 and 65, the button connection 114C can be a through hole, the rotary disk connection 115C can be a threaded hole, and the rotating connector 117 can be a screw. By passing the rotating connector 117 through the button connection 114C and threadedly connecting it to the rotary disk connection 115C, the drive unit pivot button 114 and the drive unit rotary disk 115 are connected together.

Of course, this disclosure is not limited to this.

In another embodiment, the drive unit pivot button 114 and the drive unit rotary disk 115 may be connected together in other ways.

For example, the button connection 114C can be a through hole, the rotary disk connection 115C can be a threaded connecting pin passing through the through hole, and the rotary connecting member 117 can be a nut. After the connecting pin on the drive unit rotary disk 115 passes through the through hole on the drive unit pivot button 114, the drive unit pivot button 114 and the drive unit rotary disk 115 are connected together by connecting the nut (which serves as the rotary connecting member 117) to the connecting pin on the drive unit rotary disk 115 with its threads.

For example, the drive unit pivot button 114 and the drive unit rotary disk 115 can be connected together by means of interlocking or rivet connection.

In another embodiment, the drive unit pivot button 114 and the drive unit rotary disk 115 can be integrated as one unit. In this case, the drive unit pivot button 114 can be considered as part of the drive unit rotary disk 115.

In another configuration, the drive unit pivot button 114 and the drive unit rotary disk 115 do not necessarily need to be connected together. Instead, they can be positioned to abut against each other in the direction of rotation, so that rotation of one drives rotation of the other.

For example, the drive unit pivot button 114 can be configured as a lever, and the drive unit rotary disk 115 can be provided with a receiving part to accommodate the lever-shaped drive unit pivot button 114, thereby enabling both to rotate together.

As shown in Figure 64, the pivot 100 includes an outer cover 120, a main body 130, and an inner cover 140. The outer cover 120 and the inner cover 140 together enclose a space, within which the main body 130 is located.

In the embodiment shown in Figure 65, the circumferential wall of the base 121 of the outer cover 120 may be provided with an outer cover slot 121A through which the drive unit pivot button 114 passes. The outer cover slot 121A extends circumferentially along the base 121 of the outer cover 120, thereby exposing the drive unit pivot button 114 to the pivot part 100 for convenient user operation.

Additionally, as shown in Figure 65, the inner end wall of the outer cover 120 is provided with an outer cover pivot 125. The outer cover pivot 125 cooperates with the button rotation part 114B of the drive unit pivot button 114 and the rotation disk pivot part 115B of the drive unit rotation disk 115, thereby allowing the drive unit pivot button 114 and the drive unit rotation disk 115 to rotate around the outer cover pivot 125. In the embodiment shown in Figure 65, the outer cover pivot 125 is a pivot shaft, and the button rotation part 114B and the rotation disk pivot part 115B are rotation holes. However, it should be understood that when the button rotating part 114B or the rotary disc rotating part 115B is a pivot, the outer cover rotating part 125 can also be a pivot hole.

Furthermore, as shown in Figure 65, a pivot stop 126 may be provided at the end of the outer cover pivot 125 to prevent the drive pivot button 114 and the drive rotary disc 115 from disengaging from the outer cover pivot 125. The pivot stop 126 may be, for example, a screw threaded to the end of the outer cover pivot 125, or a pin laterally inserted into the end of the outer cover pivot 125.

Next, the moving part 116 of the drive unit will be described in detail.

The drive unit moving member 116 can be configured as a disc shape as shown in Figures 64 and 65, or it can be configured as a polygon or other suitable shape.

The driving unit moving member 116 can be disposed between the driving unit rotating disk 115 and the engaging member 150. On the one hand, it is moved by the pushing force of the driving unit rotating disk 115; on the other hand, it drives the engaging member 150 to disengage from or engage with the first slot 170 or the second slot 144.

In order for the rotation of the drive unit rotary plate 115 to drive the movement of the drive unit moving member 116, the drive unit rotary plate 115 is provided with a rotary plate pushing tilting body 115A, and the drive unit moving member 116 is provided with a moving member pushing tilting body 116A. Furthermore, the rotary plate pushing tilting body 115A and the moving member pushing tilting body 116A are configured to interact, such that when the drive unit rotary plate 115 rotates, the rotary plate pushing tilting body 115A pushes the moving member pushing tilting body 116A, causing the drive unit moving member 116 to move and drive the engaging member 150.

In one embodiment, the rotary disk push tilting body 115A on the drive unit rotary disk 115 may be a protrusion or a recess provided on the side surface of the drive unit rotary disk 115. The rotary disk push tilting body 115A may be configured to tilt on the side surface of the drive unit rotary disk 115 in the direction of rotation of the drive unit rotary disk 115. Specifically, the distance between the rotary disc pushing inclined body 115A and its side surface gradually increases or decreases from one side of the rotary disc pushing inclined body 115A along the rotation direction towards the other side, causing the rotary disc pushing inclined body 115A to tilt on its side surface and in the direction of movement of the drive unit moving member 116.

Correspondingly, the moving member pushing tilt 116A on the driving part moving member 116 can also be a protrusion or a recess provided on the side surface of the driving part moving member 116, and its position corresponds to the rotary disk pushing tilt 115A. The moving member pushing tilt 116A can be provided to be inclined on the side surface of the moving member pushing tilt 116A along the rotation direction of the driving part rotary disk 115. Specifically, the distance between the moving member pushing the inclined body 116A and its side surface gradually increases or decreases from one side of the moving member pushing the inclined body 116A along the rotation direction of the drive unit's rotary disk 115 towards the other side, causing the moving member pushing the inclined body 116A to tilt towards its side surface and towards the movement direction of the drive unit's moving member 116.

This structure allows the drive unit's rotating disk 115 to push the inclined body 115A against which the moving member 116A is pressed, causing the drive unit's moving member 116 to move in a direction perpendicular to the pivot direction of the drive unit's rotating disk 115. This, in turn, drives the engaging member 150.

The rotary table pushing tilt body 115A and the moving member pushing tilt body 116A can be provided as one or more, forming one or more sets that cooperate with each other. In the embodiment shown in Figures 64 and 65, the rotary table pushing tilt body 115A and the moving member pushing tilt body 116A are provided as three sets that cooperate with each other. Providing multiple sets of rotating table pushing tilt bodies 115A and moving member pushing tilt bodies 116A that cooperate with each other allows the driving part moving member 116 to be driven more smoothly.

To improve the effect of the drive unit moving member 116 driving the engaging member 150, the drive unit moving member 116 may be provided with at least one moving member push rod 116B. The moving member push rod 116B may be in the shape of a straight rod, abutting against the engaging member 150, so that once the moving member push rod 116B moves, it will drive the engaging member 150.

In the embodiments shown in Figures 64 and 65, the movable push rod 116B extends parallel to the direction of movement of the engaging member 150 or parallel to the connecting shaft 180, thereby better driving the engaging member 150. Of course, it should be understood that the movable push rod 116B may extend inclined to the direction of movement of the engaging member 150.

Additionally, the push rod 116B of the drive unit moving member 116 can pass through the body member 130 and the inner cover 140 and abut against the engaging member 150.

To facilitate the passage of the movable push rod 116B through the body component 130, the body component 130 is provided with a hole 134 corresponding to the movable push rod 116B (see Figures 64 and 65).

To prevent the moving member push rod 116B from disengaging from the hole 134 of the body member 130 and causing accidental separation of the driving part 116 from the body member 130, in the embodiments shown in Figures 64 and 65, a push rod stop hook 116B1 may be provided at the end of the moving member push rod 116B that abuts against the engaging member 150. The push rod stop hook 116B1 is configured such that after passing through the hole 134 of the body member 130, it can be blocked by the hole wall of the hole 134 and cannot exit the hole 134.

In addition, the push rod stop hook 116B1 can also limit the travel of the moving push rod 116B.

In one embodiment, the hole 134 of the body component 130 is not precisely aligned with the push rod stop hook 116B1 of the moving member push rod 116B. Thus, when the push rod stop hook 116B1 passes through the hole 134 of the body component 130, the moving member push rod 116B undergoes elastic deformation; after the push rod stop hook 116B1 passes through the hole 134 of the body component 130, the moving member push rod 116B elastically returns to its original position, and the hole wall of the hole 134 of the body component 130 will block the push rod stop hook 116B1, preventing it from exiting the hole 134 of the body component 130. Therefore, the push rod stop hook 116B1 prevents the drive unit moving part 116 from accidentally separating from the main body part 130.

When it is necessary to disassemble the driving unit moving member 116 from the main body 130, the user only needs to apply force to the push rod stop hook 116B1, forcing the moving member push rod 116B to undergo elastic deformation. When the push rod stop hook 116B1 aligns with the hole 134 in the main body 130, the push rod stop hook 116B1 can disengage from the hole 134, thereby separating the driving unit moving member 116 from the main body 130.

The working process of the drive unit 110, including the drive unit pivot button 114, the drive unit rotary table 115, and the drive unit moving member 116, is then described in detail.

When the drive unit 110” is not actuated, the engaging member 150 engages simultaneously with the first slot 170 and the second slot 144, as shown in FIG. 5, so that the pivot unit 100 is locked in one of the pivot positions relative to the carrier body 300 (e.g., the storage position shown in FIGS. 46 to 49) and cannot pivot around the connecting shaft 180.

When it is necessary to rotate the pivot 100 from the storage position or a certain working position to another working position in the third pivot direction R3, the user applies an external force to the drive pivot button 114 to make it rotate. The drive pivot button 114 rotates from the initial button position shown in Figures 60 and 61 in the third pivot direction R3 to the button termination position shown in Figure 62, and drives the drive rotating disk 115 to rotate together in the third pivot direction R3. Therefore, as the drive unit rotary disk 115 rotates in the third pivot direction R3, its rotary disk pushes the inclined body 115A, which in turn pushes the moving member on the drive unit moving member 116 against the inclined body 116A. This causes the drive unit moving member 116 to move in a direction perpendicular to the rotation direction, thereby driving the engaging member 150 to move in the direction of disengagement from the second slot 144.

When the engaging member 150 is completely disengaged from the second slot 144, the pivot 100 unlocks and can pivot around the connecting shaft 180°. Then, under the same external force applied by the user, the pivot 100 pivots in the third pivot direction R3 (see Figures 60 to 62) until it reaches the desired pivot angle (i.e., another working position).

Subsequently, the user can release the actuation of the drive unit 110”, that is, the user no longer applies external force to the drive unit pivot button 114. The engaging member 150, under the action of the resetting member 160 (see Figures 2, 3, 5, 6, and 8), simultaneously engages again with the first slot 170 and the second slot 144, thereby locking the pivot unit 100 at that pivot angle. At the same time, the drive unit pivot button 114 will also pivot in the fourth pivot direction R4 (see Figures 60 to 62), for example, due to the force of the resetting member 160, thus returning to the initial position (this process will be described below).

Therefore, when the third embodiment 110” of the drive unit according to this disclosure is adopted, the user only needs to apply an external force in the same direction to the drive unit pivot button 114 of the drive unit 110”, for example, with their thumb. This not only rotates the drive unit pivot button 114 to unlock the pivot unit 100, but also allows the pivot unit 100 to pivot in the third pivot direction R3, greatly facilitating the user's operation.

When it is necessary to rotate the pivot 100 from one working position to another working position or storage position in the fourth pivot direction R4, the user can also apply an external force to the drive pivot button 114 to rotate it in the third pivot direction R3 until the pivot 100 is unlocked and can rotate around the connecting shaft 180 degrees. Then, the user can apply an external force in the opposite direction to the pivot 100, causing the pivot 100 to rotate in the fourth pivot direction R4 until the pivot 100 reaches the desired pivot angle (i.e., another working position or storage position). During this process, the user can use their thumb to press the drive pivot button 114 to rotate it in the third pivot direction R3 to unlock the pivot 100, and then use the other fingers to rotate the pivot 100 in the fourth pivot direction R4. This allows the user to rotate the pivot 100 with just one hand, simplifying the operation.

In another embodiment, the drive unit pivot button 114 may be configured to unlock the pivot unit 100 by rotating it in the fourth pivot direction R4, rather than in the third pivot direction R3. In this embodiment, the rotating disk pushing inclined body 115A on the drive unit rotating disk 115 and the moving member pushing inclined body 116A on the drive unit moving member 116 can be configured such that, during the rotation of the drive unit rotating disk 115 toward the fourth pivot direction R4, the rotating disk pushing inclined body 115A can push the moving member pushing inclined body 116A, thereby driving the drive unit moving member 116 to move in a direction perpendicular to the rotation direction.

Correspondingly, a pull flange (not shown) may be provided on the drive unit pivot button 114 to allow the user to pull the drive unit pivot button 114 to pivot in the fourth pivot direction R4.

In another embodiment described above, the user only needs to apply an external force in the same direction to the drive unit pivot button 114 of the drive unit 110”. This not only rotates the drive unit pivot button 114 to unlock the pivot unit 100, but also allows the pivot unit 100 to pivot in the fourth pivot direction R4, greatly facilitating the user's operation.

After the pivot 100 reaches the desired pivot angle, the user no longer applies external force to the drive pivot button 114. At this time, under the restoring force of the aforementioned reset member 160, the drive pivot button 114 will return to its initial position.

Specifically, when the user no longer applies external force to the drive unit pivot button 114, the restoring force of the reset member 160 will force the engaging member 150 to move toward and engage with the second slot 144, thereby locking the pivot unit 100 at that pivot angle. During this process, the engaging member 150 will drive the drive unit moving member 116, which abuts against it, to move toward the drive unit turntable 115. Therefore, the moving member on the drive unit moving member 116 pushes the inclined body 116A, which in turn pushes the rotating disk on the drive unit rotating disk 115, which in turn pushes the inclined body 115A. This causes the drive unit rotating disk 115 to rotate in the fourth pivot direction R4 (see Figures 60 to 62) and return to its initial position.

In another embodiment, the drive unit 110” may be provided with a drive unit reset member (not shown). When the drive unit pivot button 114 is not subjected to external force, the drive unit reset member will drive the drive unit pivot button 114 back to its initial position. The drive unit reset member may be a torsion spring surrounding the button rotation portion 114B of the drive unit pivot button 114, or it may be other elastic bodies such as springs or tension springs that can apply elastic force to the drive unit pivot button 114.

In the case where the carrier 1 has two pivots 100, the two pivots 100 are respectively coupled to the two ends of the connecting shaft 180, and a drive unit 110 can be provided at each of the two pivots 100, as shown in Figures 60 to 65.

Of course, it should be understood that a connecting shaft 180 may not be provided between the two pivoting parts 100. In this way, after the two pivoting parts 100 are unlocked by the drive unit 110', the two pivoting parts 100 can pivot independently of each other.

Additionally, as shown in Figures 58 and 59, the carrier 1 may include a synchronized unlocking assembly 500 (described below) consisting of a hinged structure 540 and two third links 550, allowing the two engaging members 150 to be linked to each other.

Synchronous Linkage

Referring to Figure 7, in one embodiment, the carrier 1 may include a synchronizing linkage assembly 200. The synchronizing linkage assembly 200 may replace the connecting shaft 180 for connecting the two pivots 100. The synchronizing linkage assembly 200 is used to synchronize the rotation of the two pivots 100 and to engage the two engaging members 150 with each other.

Referring to Figures 8 to 15, the synchronous linkage assembly 200 may include: a hinge 230, the middle portion of which is pivotally disposed on the carrier body 300; two first links 210, one end of which is pivotally connected to the two ends of the hinge 230, and the other ends of which are respectively coupled to two engaging members 150; and a second link 220, the two ends of which are respectively coupled to two body members 130.

The hinge 230 can be formed as a sheet. The hinge 230 can hinge the inner ends of the two first connecting rods 210 together to form a linkage.

The first link 210 may have a curved shape. This allows the first link 210 to be easily connected simultaneously to both the second link 220 and the hinge 230, and enables the pivoting of the hinge 230 to be converted into linear motion of the first link 210. The two first links 210 are arranged symmetrically about the pivot axis of the hinge 230.

One end of the first link 210, away from the hinge 230, may have an engaging portion 211 that engages with the engaging member 150. This engaging portion 211 passes through the receiving groove 310 of the carrier body 300 and the center hole 152 of the engaging member 150.

In one embodiment, the engaging portion 211 is formed as a notch that can clamp the engaging member 150.

Specifically, the engaging portion 211 of the first connecting rod 210 can clamp the outer edge of the central hole 152, so that the outer end of the first connecting rod 210 is coupled to the engaging member 150.

Alternatively, the first link 210 and the engaging member 150 can be coupled via rivets, screws, or other connectors.

Thus, when the engaging member 150 on one side of the carrier 300 moves (e.g., laterally along the carrier 1), this movement is transmitted via a first link 210, a hinge 230, and another first link 210 to the engaging member 150 on the other side of the carrier 300, causing the two engaging members 150 on both sides of the carrier 300 to move in opposite directions. In this disclosure, since the first link 210 is arranged in a centrally symmetrical manner about the pivot axis of the hinge 230, the two engaging members 150 on both sides move the same distance in opposite directions. Therefore, in one embodiment, only one engaging member 150 needs to be actuated to unlock both pivots 100 simultaneously.

Referring to Figure 9, the second link 220 may include a first portion 220A and a second portion 220B. The first portion 220A and the second portion 220B are symmetrical to each other and can be connected together. Alternatively, the second link 220 may be formed integrally. The first portion 220A and the second portion 220B may each be formed in, for example, the shape of a frame. Specifically, the frame may be a rectangular frame missing one side.

Referring to Figures 9 and 16, a groove 221 may be provided on the second link 220. The groove 221 may be elongated along the length of the second link 220. The first link 210 may be confined within the groove 221 by a pin 212, so that the groove 221 can guide the movement of the first link 210. Since the second link 220 is formed as a frame, a groove 221 may be formed on the upper and lower parts of the second link 220, respectively, with their positions aligned with each other. In this disclosed embodiment, since the second link 220 can be arranged laterally along the vehicle 1, and the slide 221 can be elongated along the length of the second link 220, the slide 221 of the second link 220 guides the first link 210 to move laterally along the vehicle 1. In one embodiment, a slide 221 is provided on the first part 220A and the second part 220B respectively, and the two first links 210 are respectively confined within the slides 221 on the first part 220A and the second part 220B by pins 212.

In one embodiment, the slide 221 may be located in other positions, such as on the carrier body 300, as long as the arrangement of the slide 221 allows the first link 210 to drive the engaging member 150 in linear motion.

Referring to Figure 9, each of the first part 220A and the second part 220B can be formed into a rectangular frame resembling the letter "C". In other words, each of the first part 220A and the second part 220B has three sides of a rectangle, but lacks a fourth side, thus forming an open end 222.

In one embodiment, both part 220A and part 220B can be formed by bending the sheet metal, but this disclosure is not limited thereto.

The portion of one of the first part 220A and the second part 220B near the open end 222 may be narrowed inward to allow the open ends 222 of the first part 220A and the second part 220B to be inserted into each other.

In one embodiment, as shown in Figure 9, the portion 220A near the open end 222 narrows inward.

Alternatively, in one embodiment, the portion of the second part 220B near the open end 222 narrows inward.

Both the first part 220A and the second part 220B may have perforations 223 formed therein. Specifically, each of the first part 220A and the second part 220B may have two perforations 223 that are aligned with each other.

Similarly, each first link 210 may have two aligned holes 214 formed on it.

The hinge 230 has perforations 231 formed at its center and both ends.

The central through hole 231 of the hinge 230, the through hole 223 of the first portion 220A, and the through hole 223 of the second portion 220B are pivotally connected by a connecting pin 232.

The through holes 231 on both sides of the hinge 230 are pivotally connected to the through holes 214 on the two first connecting rods 210 via a connecting pin 232.

The second connecting rod 220 passes sequentially through the first slot 170 of the carrier body 300, the center hole 152 of the engaging member 150, and the center hole 143 of the inner cover 140, finally engaging with the center hole 133 of the body member 130.

Referring to Figures 9, 14, and 15, the second link 220 can be formed as a frame structure, and at least a portion of the first link 210 can be disposed within the second link 220, thereby saving space required for the synchronizing link assembly 200.

The two ends of the second link 220 can be connected to two body parts 130 (e.g., by means of rivets, screws, or welding), so that the two body parts 130 on both sides of the load-bearing body 300 rotate synchronously, thereby driving the two pivoting parts 100 to rotate synchronously.

Referring to Figures 11 and 14, when the drive unit 110 is not actuated, the engaging member 150 engages simultaneously with the first slot 170 and the second slot 144, thus fixing the pivot unit 100 to the carrier body 300 and preventing it from pivoting.

In one embodiment, referring to Figures 13 and 15, when a drive part 110 on one side of the carrier body 300 is actuated (e.g., pressed into drive part 110), the latching part 111 of drive part 110 actuates the engaging member 150 on the same side to move in a direction disengaging from the second slot 144 on the same side. The movement of the engaging member 150 causes the first link 210 on the same side to move. The movement of the first link 210 causes the hinge 230 to rotate, and the rotation of the hinge 230 causes another first link 210 to move in the opposite direction, thereby causing the engaging member 150 on the other side of the carrier body 300 to move in a direction disengaging from the corresponding first slot 170 and/or second slot 144. In this embodiment, the drive unit 110 may be configured as a button, for example.

In one embodiment, when a drive unit 110 on one side of the carrier body 300 is actuated (e.g., pulled out), the drive unit 110 can actuate a locking member 150 on the same side to move in a direction disengaging from the first locking slot 170 on the same side (e.g., one end of the drive unit 110 is connected to the locking member 150). The movement of the locking member 150 drives the first link 210 on the same side to move, the movement of the first link 210 causes the hinge 230 to rotate, and the rotation of the hinge 230 drives another first link 210 to move in the opposite direction, thereby causing the locking member 150 on the other side of the carrier body 300 to move in a direction disengaging from the corresponding first locking slot 170. In this embodiment, the drive unit 110 may be configured as, for example, a handle or a pull ring.

The actuating drive unit 110 requires the restoring force of the overcoming reset member 160. When the engaging members 150 on both sides of the carrying body 300 are completely disengaged from the corresponding first slot 170 and/or second slot 144, the pivot units 100 on both sides of the carrying body 300 can pivot synchronously. At this time, through the linkage 220, the pivot units 100 on both sides can be driven to pivot synchronously to a position suitable for the current vehicle seat shape, so that the vehicle 1 of this application can adapt to different vehicle types. When both pivot parts 100 have pivoted to the desired angle, the actuation of the aforementioned drive part 110 is released, causing the engaging members 150 on both sides of the carrier body 300 to simultaneously engage with the corresponding first slot 170 and second slot 144, thus preventing undesirable pivoting of the pivot parts 100. In other words, the pivot parts 100 can be locked in a specific pivoting position after pivoting.

In this embodiment, unlocking both pivot units 100 can be achieved by actuating only one drive unit 110.

In one embodiment, the vehicle 1 may have a drive unit 110 on only one side, thereby reducing the number of drive units 110 and lowering costs.

In one embodiment, the vehicle 1 may have drive units 110 on both sides, thereby allowing selection of which side's drive unit 110 to be driven, thus providing better operational convenience.

The first implementation of synchronous unlocking components

Referring to Figures 18 to 19A, in one embodiment, the carrier 1 may include a synchronized unlocking assembly 500. In this embodiment, the carrier 1 does not include the synchronized linkage assembly 200 as shown in Figure 7, and includes two connecting shafts 180A and 180B. Referring to Figure 25, the front connecting shaft 180A of the two connecting shafts 180A and 180B is used to connect the two pivots 100. The rear connecting shaft 180B of the two connecting shafts 180A and 180B connects the two sides 330 at the bottom of the carrier body 300. Of the two connecting shafts 180A and 180B mentioned above, the front connecting shaft 180A is used to synchronously rotate the two pivots 100, and the synchronous unlocking assembly 500 engages the two locking members 150. The synchronous unlocking assembly 500 can be substantially located inside the carrier body 300. The two connecting shafts 180A and 180B can optionally engage with an external base 4000 (see Figure 37A, described below).

Referring to Figures 19B, 21B, and 22B, the synchronous unlocking component 500 may include a mounting base 510, a fastener 520, and a wire component 530. Two mounting bases 510 can be respectively fixed to two engaging members 150 by means of two fasteners 520. Two fasteners 520 can respectively fix two portions of the wire component 530 to the two mounting bases 510, and each fastener 520 passes through the corresponding mounting base 510 and is fixed to the corresponding engaging member 150. In this way, two portions of the wire component 530 are respectively connected to the two engaging members 150 (linked arrangement). Optionally, the mounting base 510 and the engaging member 150 are integrally formed. Optionally, the mounting base 510 and the engaging member 150 are separately formed. It is understood that the wire component 530 can be connected to the engaging member 150 by other means. In other words, the mounting bracket 510 and the fastener 520 can be replaced or omitted.

Referring to Figures 19A and 19B, the wire component 530 may include an outer casing 531 and a core 532. The core 532 is slidable within the outer casing 531. The core 532 may be exposed outside the outer casing 531 at two locations. Two fasteners 520 respectively secure portions of the core 532 at these two locations (i.e., the two locations exposed outside the outer casing 531) to two mounting seats 510. In other words, the two locations of the core 532 exposed outside the outer casing 531 are respectively engaged with two engaging members 150.

Referring to Figures 19B and 21B, in one embodiment, the core 532 may be a steel wire. The core 532 may include two wire ends 5321. The two wire ends 5321 may be exposed outside the jacket 531. The two wire ends 5321 may be respectively secured to two mounting bases 510 by two fasteners 520, such that movement of each mounting base 510 can be transmitted to the core 532 via the corresponding wire end 5321.

Referring to Figures 21A to 23B, the wire component 530 may be formed as a loop and bent in the manner of the number "8" (i.e., a portion of the loop is twisted 180°), but this disclosure is not limited thereto. In this way, movement of one engaging member 150 in one direction is transmitted to the core 532, causing the core 532 to slide within the outer casing 531, and causing the other engaging member 150 to move in the opposite direction. It is understood that the wire component 530 may be formed in other shapes, as long as, after one engaging member 150 is actuated, the core 532 drives the other engaging member 150 to move in the opposite direction to the movement of the aforementioned engaging member 150.

Referring to Figures 19B and 21B, the carrier body 300 may include two guide slots 350. Two retaining seats 510 may be respectively located within the two guide slots 350, such that each retaining seat 510 (and the retaining member 520 on the retaining seat 510) can move within the corresponding guide slot 350. The length of each guide slot 350 may be greater than or equal to the distance the engaging member 150 can move. The two guide slots 350 may respectively guide the movement direction of the two sets of retaining seats 510 and retaining members 520, thereby guiding the two engaging members 150 to move in opposite directions. The retaining member 520 may be a screw, but this disclosure is not limited thereto.

Referring to Figures 19A and 19B, when the left drive unit 110 is actuated, the left engaging member 150 is pushed and disengaged from the second slot 144 on the inner cover 140 of the left pivot unit 100. Simultaneously, the portion of the core 532 fixed to the left engaging member 150 drives the core 532 to move. This movement is transmitted through the core 532 to the right engaging member 150 (because another portion of the core 532 is fixed to the right engaging member 150). Therefore, the right engaging member 150 moves synchronously with the left engaging member 150 in opposite directions. When the right drive unit 110 is actuated, the above components will move in opposite directions. In this way, by actuating one drive unit 110, the pivot units 100 on both sides can be unlocked simultaneously, thereby simplifying the operation of the vehicle 1.

Referring to Figures 19A and 19B, in this embodiment, the gear shifting structure 400 may include two driving units 110, each movably disposed on one of the two pivot units 100; however, this disclosure is not limited to this. In other embodiments, the gear shifting structure 400 may include only one driving unit 110, which may be movably disposed on one of the two pivot units 100. By actuating one driving unit 110 through the synchronous unlocking component 500, the pivot units 100 on both sides can be unlocked synchronously.

The jacket 531 enables the wire component 530 to maintain a fixed shape during movement of the core 532. The jacket 531 can be flexible and made of metal or plastic, but this disclosure is not limited thereto.

The core 532 is capable of sliding and changing shape within the rigid outer casing 531. The core 532 may be flexible and made of metal, specifically stainless steel, but this disclosure is not limited thereto.

Referring to Figures 24A and 25, compared to other embodiments, in this embodiment, because the mechanism of the synchronous unlocking component 500 is relatively simplified and occupies less volume, most of the synchronous unlocking component 500 can be housed inside the vehicle body 300. The wiring components 530 of the synchronous unlocking component 500 are not visible or only partially visible from below the vehicle 1. Even if a small portion of the wiring components 530 protrudes from the exterior of the vehicle body 300, it can be covered with a seat cover, thus improving the overall aesthetics of the vehicle 1.

In the above embodiment, the line component 530 is a single piece. However, this disclosure is not limited to this.

In another embodiment, as shown in Figures 32A to 33, the wire component 530 may include a first wire component 530A and a second wire component 530B. That is, the wire component 530 may be composed of two components.

Specifically, as shown in Figures 32B and 33, the first thread component 530A includes a first outer jacket 531A and a first core portion 532A slidably disposed inside the first outer jacket 531A. The first core portion 532A has two first exposed portions 532A1 and 532A2 exposed outside the first outer jacket 531A.

Furthermore, the first outer jacket 531A is configured not to move with the first core 532A. For example, the first outer jacket 531A may be partially or completely fixed to the carrier body 300. In one embodiment, the ends of the two exposed first exposed portions 532A1, 532A2 of the first outer jacket 531A are fixed to the carrier body 300.

Similarly, the second thread component 530B includes a second outer jacket 531B and a second core portion 532B slidably disposed inside the second outer jacket 531B. The second core portion 532B has two second exposed portions 532B1 and 532B2 that are exposed outside the second outer jacket 531B.

Furthermore, the second outer jacket 531B is configured not to move with the second core 532B. For example, the second outer jacket 531B may be partially or completely fixed to the carrier body 300. In one embodiment, the ends of the two exposed second exposed portions 532B1, 532B2 of the second outer jacket 531B are fixed to the carrier body 300.

Of course, this disclosure is not limited to this, and the wire component 530 can take other forms. For example, the wire component 530 may only have a core, and at least one wire component guiding structure (not shown), such as a guide groove, guide hook, or guide ring, may be provided on the carrier body 300. This wire component guiding structure is configured to guide the movement of the wire component 530 such that the two ends of the wire component 530 move in opposite directions.

In the embodiments shown in Figures 32B and 33, the two first exposed portions 532A1 and 532A2 are respectively fixed to the two fixing seats 510 by two fasteners 520, and the two second exposed portions 532B1 and 532B2 are also respectively fixed to the two fixing seats 510 by two fasteners 520. Since the fixing seats 510 are disposed on the engaging members 150, the movement of the first core 532A and the second core 532B will be transmitted to the two engaging members 150 via the two fixing seats 510, thereby causing the two engaging members 150 to move in opposite directions.

As previously described, the fixing base 510 can be integrally formed with the engaging member 150 or formed separately. When the fixing base 510 and the engaging member 150 are formed separately, the two fasteners 520 can respectively fix the two fixing bases 510 to the two engaging members 150.

To facilitate fixing the first core 532A and the second core 532B to the two mounting bases 510, referring to FIG33, at least one of the two first exposed portions 532A1 and 532A2 may be provided with a first wire end 532A3. The first wire end 532A3 may be fixed to the mounting base 510 by the fixing member 520 (see the first wire end 532A3 on the left side in FIG33), or it may be fixed to the mounting base 510 by the first wire end connector 532A4 (see the first wire end 532A3 on the right side in FIG33). The first wire end connector 532A4 may be sleeve-shaped, as shown in FIG33, and the two are fixed by fitting the first wire end connector 532A4 and the mounting base 510 together. It should be understood that the first wire connector 532A4 can adopt other structures, as long as it can secure the first wire connector 532A4 and the fixing base 510 together.

At least one of the two second exposed portions 532B1 and 532B2 may also be provided with a second wire end 532B3. This second wire end 532B3 can be fixed to the fixing base 510 by the fixing member 520 (see the right-hand second wire end 532B3 in Figure 33), or it can be fixed to the fixing base 510 by a second wire end connector 532B4 (see the left-hand second wire end 532B3 in Figure 33). The second wire end connector 532B4 may have the same structure as the first wire end connector 532A4, or it may have a different structure, as long as it can fix the second wire end 532B3 and the fixing base 510 together.

Of course, this disclosure is not limited to this; the two first exposed portions 532A1 and 532A2 can be directly connected to the two locking members 150, respectively. The two second exposed portions 532B1 and 532B2 can also be directly connected to the two locking members 150, respectively. Therefore, the two fixing bases 510 can be omitted.

The following describes the working process of the first-line component 530A in its coordinated operation.

As shown in Figures 32B and 33, when the left engaging member 150 is actuated by the drive part 110 and moves to the right in the figure, the fixing seat 510 on the left engaging member 150 also moves to the right along the guide groove 350 on the left (see Figure 32B). Thus, the first thread member 530A functions in conjunction, and the first exposed portion 532A1 of the first thread member 530A, connected to the fixing seat 510 on the left, is driven by the fixing seat 510 and moves to the right. Since the first outer jacket 531A does not move with the first core 532A, the first exposed portion 532A1 on the left extends further to the right from the first outer jacket 531A. The movement of the first exposed portion 532A1 on the left side will cause the first core portion 532A to slide inside the first outer jacket 531A, thereby causing the first exposed portion 532A2 on the right side to retract more into the first outer jacket 531A towards the left in the figure. That is, the first thread member 530A can be configured such that the direction in which one of the first exposed portions 532A1 extends out of the first outer jacket 531A is opposite to the direction in which the other first exposed portion 532A2 retracts into the first outer jacket 531A. As a result, the first exposed portion 532A2 on the right side drives the right fixing seat 510 to move to the left along the right guide groove 350 (see Figure 32B), thereby driving the right engaging member 150 to move to the left. This allows the left engaging member 150 to drive the right engaging member 150 to move synchronously in opposite directions, thus simultaneously unlocking the pivots 100 on both sides.

As shown in Figure 33, the front connecting shaft 180A, which connects the two pivoting parts 100, enables the two pivoting parts 100 to pivot synchronously.

On the other hand, when the left engaging member 150 is no longer actuated by the driving part 110, the left engaging member 150 will move to the left under the restoring force of the left resetting member 160, and at the same time, the right engaging member 150 will move to the right under the restoring force of the right resetting member 160. Therefore, the left first exposed portion 532A1 retracts further into the first outer cover 531A to the left, and the right first exposed portion 532A2 extends further out of the first outer cover 531A to the right; the right second exposed portion 532B1 retracts further into the second outer cover 531B to the right, and the left second exposed portion 532B2 extends further out of the second outer cover 531B to the left. Finally, the two locking components 150 simultaneously engage with their respective first locking slot 170 and second locking slot 144, thereby achieving synchronous locking of the two pivot units 100.

Similarly, as shown in Figures 32B and 33, when the right-side engaging member 150 is actuated by the drive unit 110 and moves to the left, the fixing seat 510 on the right-side engaging member 150 also moves to the left along the right-side guide groove 350 (see Figure 32B). Thus, the second thread component 530B performs a coordinated action. The working process of the second thread component 530B is basically the same as that of the first thread component 530A, except that the movement directions of the related components are reversed, which will not be described in detail here.

A second implementation of synchronous unlocking components

Figures 34 to 36 illustrate a second embodiment of the synchronous unlocking assembly of the vehicle according to this disclosure. The main difference between this second embodiment and the first embodiment of the synchronous unlocking assembly described above with reference to Figures 18 to 25 and Figures 32A to 33 is that a linkage structure replaces the wire component in the second embodiment.

As shown in Figures 34 to 36, the synchronous unlocking assembly 500 includes a hinged structure 540 and two third links 550. The hinged structure 540 can be formed as a plate, a rod, or a block.

Specifically, the hinged structure 540 is rotatably mounted on the vehicle body 300. In the embodiment shown in Figures 34 and 35, the synchronous unlocking assembly 500 includes a hinged structure mounting base 560, which is fixed to the vehicle body 300, for example, by a mounting base fastener 561, and the hinged structure 540 is rotatably mounted on the hinged structure mounting base 560. For example, a hinge pin 541 is connected to the middle of the hinged structure 540, and the two ends of the hinge pin 541 are rotatably connected to the hinged structure mounting base 560.

It should be understood that the hinge structure 540 can be directly disposed on the vehicle body 300, in which case the two ends of the hinge pin 541 are rotatably connected to the vehicle body 300.

One end of each of the two third links 550 is hinged to one end of the hinged structure 540, thereby linking the two third links 550 together.

The other ends of the two third links 550 are respectively hinged to two locking members 150, allowing the movement between the third links 550 and the locking members 150 to be transmitted between them.

In the embodiment shown in Figure 36, the engaging member 150 is provided with an engaging member connection structure 154, and the other end of the third link 550 is hinged to the engaging member connection structure 154. The engaging member connection structure 154 can be fixed to the engaging member 150 by means of a fastener 520.

In the second embodiment, the working process of the hinged structure 540 and the two third links 550 in synergy is largely the same as that of the hinged component 230 and the two first links 210 described above.

When the engaging member 150 on one side of the carrying body 300 is actuated by the drive unit 110 and moves toward the engaging member 150 on the other side (e.g., moving laterally along the carrier 1), the movement is transmitted to the engaging member 150 on the other side via a third link 550, a hinge structure 540 and another third link 550. Because the hinge structure 540 rotates around the hinge pin 541 in its middle, the tangential directions of its two ends are opposite. This causes the two third links 550, which are hinged to the two ends, to also have opposite motion components. Consequently, the third link 550 on the other side drives the engaging member 150 on the other side, which is hinged to it, to move synchronously towards the engaging member 150 on the aforementioned side, thereby simultaneously unlocking the pivots 100 on both sides.

Furthermore, since the two third links 550 are arranged in a centrally symmetrical manner with respect to the rotation axis of the hinge structure 540 (e.g., hinge pin 541), the two engaging members 150 on both sides move the same distance in opposite directions. Therefore, in one embodiment, only one engaging member 150 needs to be actuated to achieve synchronous unlocking of the two pivots 100.

As shown in Figures 35 and 36, the front connecting shaft 180A, which connects the two pivoting parts 100, enables the two pivoting parts 100 to pivot synchronously.

On the other hand, when one engaging member 150 is no longer actuated by the driving unit 110, both engaging members 150 will move away from each other under the restoring force of their respective resetting members 160. Finally, the two engaging members 150 simultaneously engage with their respective first slots 170 and second slots 144, thereby achieving synchronous locking of the two pivot units 100.

In a second embodiment of the synchronized unlocking assembly, as shown in Figure 34, since most of the synchronized unlocking assembly 500 can be housed within the vehicle body 300, and the portion of the synchronized unlocking assembly 500 exposed above the vehicle body 300 can be covered by a seat cover, the overall aesthetics of the vehicle 1 are improved.

Base for mounting the vehicle

To facilitate connection of the vehicle 1 to the vehicle seat, this disclosure also provides another solution, as shown in Figure 37A, whereby the vehicle 1 is connected to the vehicle seat via a base 4000.

According to this disclosure, the base 4000 can be pre-connected to the vehicle seat via conventional methods such as seat belts or ISOFIX. Thus, when the vehicle 1 is connected to or removed from the base 4000, that is, when the vehicle 1 is connected to or removed from the vehicle seat, this method greatly improves the convenience of connecting or removing the vehicle 1 from the vehicle seat.

The base 4000 according to this disclosure can be used to mount the carrier 1, as described above, including the pivot 100. For ease of description, as previously stated, the direction the infant faces in the carrier 1 is defined as "front," the direction facing away is defined as "rear," and the left-right direction of the infant in the carrier 1 is defined as "lateral," as shown in Figures 37A to 40. It should be understood that positional terms such as "front," "rear," and "lateral" are used only for clarity and convenience of description and are not intended to limit this disclosure.

As shown in Figures 38 and 39, the base 4000 is provided with a clearance space 4800, which can be disposed inside the front side of the base 4000, corresponding to the position of the pivot part 100 of the vehicle 1, so that when the vehicle 1 is placed on the base 4000, the clearance space 4800 can accommodate the pivot part 100 of the vehicle 1. For example, the clearance space 4800 can be the space formed between the two side walls of the front part of the base 4000 and the two base protrusions 4300 (described later) and the upper surface of the base 4000. To ensure that the width of the clearance space 4800 is sufficient to accommodate the pivot 100, as shown in Figure 39, a recessed portion 4820 can be formed on the side wall of the base 4000 forming the clearance space 4800. This recessed portion 4820 extends downward from the top of the side wall to the middle of the side wall. Thus, when the carrier 1 is placed on the base 4000, the clearance space 4800 can accommodate the pivot 100 of the carrier 1. Before the carrier 1 is placed on the base 4000, the pivot 100 can be adjusted to a suitable pivot position, for example, to a retractable pivot position, depending on the clearance space 4800.

Figures 37A to 45 illustrate one embodiment of the base 4000 of the mounting carrier 1 according to this disclosure.

In one embodiment, as shown in Figures 38 and 39, the base 4000 according to this disclosure includes a base engagement member 4100 and a base operating member 4200. The base engagement member 4100 is used to engage the carrier 1, and the base operating member 4200 is used to drive the base engagement member 4100.

The base connector 4100 and its related components will be described in detail below.

As shown in Figures 38, 39, and 40 to 42, the base coupling 4100 is configured on the base 4000 to move between an engaged position and a non-engaged position. In the engaged position, the base coupling 4100 engages with the front connecting shaft 180A of the carrier 1, thereby connecting the carrier 1 to the base 4000; in the non-engaged position, the base coupling 4100 disengages from the front connecting shaft 180A, thereby allowing the carrier 1 to move away from the base 4000.

As shown in Figure 40, after the base engagement member 4100 moves to the non-engaged position under the drive of the base operating member 4200, it can return to the engaged position by means of the base elastic member 4500. The base elastic member 4500 is configured to drive the base engagement member 4100 toward the engaged position. In the embodiment shown in Figure 40, the base elastic member 4500 is a torsion spring. However, the base elastic member 4500 can be other forms of elastic member such as a compression spring or a hydraulic rod, as long as it can drive the base engagement member 4100 toward the engaged position. Furthermore, it should be understood that the base elastic member 4500 is not essential to this disclosure, and the base engagement member 4100 can be configured to return to the engaged position under the drive of the base operating member 4200.

To ensure a more stable placement of the carrier 1 within the base 4000, in the embodiments shown in Figures 38 to 42, the base connector 4100 may include a front base connector 4100A and a rear base connector 4100B spaced apart along the front-rear direction of the base 4000. The front base connector 4100A is located at the front of the base 4000, and the rear base connector 4100B is located at the rear of the base 4000.

Correspondingly, as shown in Figure 25, the carrier 1 may include a rear connecting shaft 180B in addition to the front connecting shaft 180A. The rear connecting shaft 180B connects to the two sides 330 of the carrier body 300 at the bottom, and is spaced a certain distance from the front connecting shaft 180A along the front-rear direction of the carrier 1. This allows the front base connector 4100A to engage or disengage from the front connecting shaft 180A, and the rear base connector 4100B to engage or disengage from the rear connecting shaft 180B. This configuration prevents the carrier 1 from tipping over on the base 4000.

During the process of the user placing the carrier 1 onto the base 4000, in order to facilitate the user moving the base connector 4100 to the non-engaged position without operating the base operating member 4200, the front base connector 4100A and the rear base connector 4100B are provided with an end structure. In the embodiments shown in Figures 38 to 40, the front base connector 4100A and the rear base connector 4100B have the same end structure, and the front base connector 4100A will be described here as an example. The end of the front base connector 4100 that engages with the front connecting shaft 180A is provided with a connector ramp 4130. The connector ramp 4130 is configured such that when the front base connector 4100A and the front connecting shaft 180A are ready to engage, the front connecting shaft 180A can abut against the connector ramp 4130, thereby pushing the front base connector 4100A towards a non-engaged position, thus making it more convenient for the user.

As shown in Figure 25, in one embodiment, the base connector 4100 may be a base connector hook pivotally disposed on the base 4000. The base connector 4100 may include a front base connector hook 4100A and a rear base connector hook 4100B (see Figures 38 to 40).

In this embodiment, as shown in FIG40, the end of the front base engaging hook 4100A (described below) that engages with the front connecting shaft 180A shown in FIG25 is provided with a engaging inclined surface 4130. The engaging inclined surface 4130 is inclined relative to the horizontal direction, so that when the front base engaging hook 4100A and the front connecting shaft 180A are ready to engage, the front connecting shaft 180A can abut against the engaging inclined surface 4130, thereby generating a pivoting torque on the front base engaging hook 4100A, pushing the front base engaging hook 4100A to pivot in the first rotation direction R1 to reach the non-engaged position. Similarly, as shown in Figure 40, the end of the rear base engagement hook 4100B (described below) that engages with the rear connecting shaft 180B can also be provided with an engagement ramp 4130. The engagement ramp 4130 is inclined relative to the horizontal direction, so that when the rear base engagement hook 4100B and the rear connecting shaft 180B are ready to engage, the rear connecting shaft 180B can abut against the engagement ramp 4130, thereby generating a pivoting torque on the rear base engagement hook 4100B, pushing the rear base engagement hook 4100B to pivot in the second rotation direction R2 to reach the non-engaged position. It should be understood that in this embodiment, since the direction in which the front base hook 4100A rotates toward the non-engaged position (i.e., the first rotation direction R1) is different from the direction in which the rear base hook 4100B rotates toward the non-engaged position (i.e., the second rotation direction R2), the inclination direction of the engagement ramp 4130 of the front base hook 4100A is also different from the inclination direction of the engagement ramp 4130 of the rear base hook 4100B. However, if the front base hook 4100A and the rear base hook 4100B are configured to rotate toward the non-engaged position in the same direction, then the inclination direction of the engagement ramp 4130 of the front base hook 4100A can be configured to be the same as the inclination direction of the engagement ramp 4130 of the rear base hook 4100B.

In the embodiment shown in Figure 40, the base hook 4100 is pivotally connected to a hook retainer 4110, which is fixed to the base 4000. In other embodiments, the base hook 4100 may be directly connected to the base 4000. Furthermore, the base hook 4100 is not limited to pivoting; it may also be slidable.

To facilitate better placement of the carrier 1 within the base 4000, in the embodiments shown in Figures 38 and 39, the base 4000 may have a base protrusion 4300 on its surface in contact with the carrier 1. The base protrusion 4300 has a base groove 4310 capable of accommodating the front connecting shaft 180A and the rear connecting shaft 180B. Furthermore, a base engaging hook 4100 is at least partially movably disposed within the base groove 4310 and configured such that, in the engaged position, the base engaging hook 4100 can lock the front connecting shaft 180A and the rear connecting shaft 180B within the base groove 4310; and in the non-engaged position, the base engaging hook 4100 allows the front connecting shaft 180A and the rear connecting shaft 180B to enter or leave the base groove 4310.

Next, a detailed description will be given of the base operating component 4200 and its related parts.

In the base 4000 according to this disclosure, a base operating member 4200 is movably disposed on the base 4000 and configured to directly or indirectly drive the base engaging member 4100 toward a non-engaged position.

In the embodiment shown in Figures 38 to 42, where the base connector 4100 includes a front base connector 4100A and a rear base connector 4100B, the base operating member 4200 can be configured to directly drive the rear base connector 4100B to pivot in the second rotation direction R2 as shown in Figure 40 (i.e., move towards the non-engaged position), and simultaneously indirectly drive the front base connector 4100A to pivot in the first rotation direction R1 (i.e., move towards the non-engaged position) via a base linkage 4400. In this embodiment, the pivot direction R1 of the front base connector 4100A and the pivot direction R2 of the rear base connector 4100B are opposite. However, it should be understood that the pivot direction R1 of the front base connector 4100A and the pivot direction R2 of the rear base connector 4100B can be set to the same. For example, the rear base connector 4100B can be configured to pivot towards the first rotation direction R1 to reach the non-engaged position.

The base linkage 4400 can be a flexible component made of various materials such as wire, cord, or rope, or a rigid component in the shape of a rod, plate, or block. It is used to transmit the movement of the base operating component 4200 to the front base connector 4100A.

More specifically, as shown in Figures 39 to 44, the base operating member 4200 includes: an operating member body 4210 configured to be operable from the outside of the base 4000; and an operating member extension 4220 extending from the operating member body 4210 toward the interior of the base 4000 to contact and actuate the base engaging member 4100.

In the embodiments shown in Figures 40, 43, and 44, the operating member body 4210 is provided with an operating member elongated groove 4210A extending along the front-rear direction of the base 4000, and the base 4000 is provided with a base protrusion 4600 passing through the operating member elongated groove 4210A (see Figures 43 and 44), allowing the base operating member 4200 to move relative to the base 4000. Furthermore, since the base protrusion 4600 can only slide within the operating member elongated groove 4210A, the position and travel of the base operating member 4200 relative to the base 4000 are restricted, thereby preventing the base operating member 4200 from accidentally detaching from the base 4000.

Of course, this disclosure is not limited to this. In another embodiment, as shown in Figures 40, 43, and 44, the operating member extension 4220 is provided with an operating member limiting groove 4220B extending along the front-rear direction of the base 4000, and the base 4000 is provided with a base limiting post 4910 passing through the operating member limiting groove 4220B. This configuration structure also restricts the movement of the base operating member 4200 relative to the base 4000. This configuration structure can be used in conjunction with the aforementioned configuration structure of the operating member elongated groove 4210A and the base protrusion 4600, or it can be used independently.

To ensure more stable movement of the base operating member 4200 relative to the base 4000, the base 4000 may be provided with a U-shaped base limiting rib 4920. The operating member extension 4220 may be configured to pass through the base limiting rib 4920 and move along it. This configuration can be used in conjunction with the aforementioned configuration of the operating member elongated slot 4210A and the base protrusion 4600, or the configuration of the operating member limiting groove 4220B and the base limiting post 4910, or it can be used independently.

Furthermore, the base operating component 4200 can drive the base connector 4100 in various ways.

In the embodiments shown in Figures 40 and 41, the operating member extension 4220 of the base operating member 4200 is provided with an elongated operating member drive groove 4220A; the base connecting member 4100 is provided with a connecting member drive pin 4120 (see Figure 41), and the connecting member drive pin 4120 passes through the operating member drive groove 4220A. Furthermore, the extension direction of the operating member drive groove 4220A is inclined to the movement direction of the base operating member 4200. This means that when the base operating member 4200 moves relative to the base 4000, the operating member drive groove 4220A drives the engaging member drive pin 4120 to slide within it. The sliding direction of the engaging member drive pin 4120 within the operating member drive groove 4220A is also inclined to the movement direction of the base operating member 4200. Therefore, the base engaging member 4100 will rotate or move, thereby enabling the base engaging member 4100 to move towards a non-engaged position.

As shown in Figure 40, when the base operating member 4200 is moved by operation, its operating member extension 4220 moves synchronously, driving the engagement drive pin 4120 (see Figure 41) of the rear base engagement member 4100B through the operating member drive groove 4220A of the operating member extension 4220, causing the rear base engagement member 4100B to pivot towards the second rotation direction R2 (i.e., towards the non-engaged position). Simultaneously, the base linkage 4400, connected to the operating member extension 4220, transmits the movement of the base operating member 4200 to the front base engagement member 4100A, and drives the front base engagement member 4100A to pivot towards the first rotation direction R1 (i.e., towards the non-engaged position).

Of course, this disclosure is not limited to this; the base operating member 4200 can drive the base engaging member 4100 in other ways. For example, in an embodiment where the direction of movement of the base operating member 4200 is the same as the direction of movement of the base engaging member 4100 toward the non-engaged position, the base operating member 4200 can be fixed together with or formed as an integral part of the base engaging member 4100, thereby achieving synchronous movement. Alternatively, an intermediate component similar to a base linkage 4400 can be provided between the base operating member 4200 and the base engaging member 4100, through which the movement of the base operating member 4200 is transmitted to the base engaging member 4100. Alternatively, the operating member extension 4220 of the base operating member 4200 extends not only to the rear base connector 4100B but also to the front base connector 4100A, thereby allowing the operating member extension 4220 of the base operating member 4200 to simultaneously drive the rear base connector 4100B and the front base connector 4100A to rotate in the same direction, thus eliminating the need for the base linkage 4400.

To avoid the unsightly appearance or potential damage to internal components caused by exposed base operating components 4200, the base 4000 also includes a bottom cover 4700, as shown in Figure 45. The bottom cover 4700 is fixed to the base 4000 and partially covers the base operating components 4200. This partial coverage of the base operating components 4200 by the bottom cover 4700 not only protects the internal components but also allows the user to access and operate the base operating components 4200 from the outside of the base 4000.

A second implementation of the base for mounting the vehicle

Figures 66 to 74 illustrate a second embodiment of the base 4000 of the mounting carrier 1 according to the present disclosure, which differs from the first embodiment of the base 4000 described above with reference to Figures 37 to 45. The main difference lies in that, in the first embodiment, the base operating member 4200 is a single component, and the user drives the base engaging member 4100 by translating this single component; while in the second embodiment, the base operating member 4200 is composed of multiple components, and the user drives the base engaging member 4100 by rotating one of the components.

Specifically, in a second embodiment of the base 4000, the base operating member 4200 includes an operating member rotating part 4230 and an operating member driving part 4240.

As shown in Figures 67 and 69, the rotating part 4230 of the operating member is rotatably connected to the base 4000.

The operating element rotating part 4230 is configured to be operable from outside the base 4000, allowing it to rotate. The operating element rotating part 4230 may have a block-shaped, plate-shaped, rod-shaped, or other specially designed structure.

In one embodiment, as shown in FIG. 67, the base operating member 4200 may include an operating member rotation axis 4250, around which the operating member rotating part 4230 rotates.

It should be understood that the operating member rotation shaft 4250 can be integrated with the operating member rotation part 4230, or it can be a separate component independent of the operating member rotation part 4230. The base 4000 may have a shaft hole (not shown) for the operating member rotation shaft 4250 to rotate within it. Alternatively, the operating member rotation shaft 4250 can be integrated with the base 4000, and the operating member rotation part 4230 may have a shaft hole for the operating member rotation shaft 4250 to rotate within it.

In another embodiment, the base operating member 4200 may not include the operating member rotation shaft 4250, but instead an arc-shaped guide rail (not shown) is formed on the base 4000, along which the operating member rotating part 4230 can rotate.

The rotating part 4230 of the operating member rotates on the base 4000, so that the base operating member 4200 does not need to extend out of the base 4000 as in the first embodiment. This is advantageous for applications with limited operating space.

The operating member drive unit 4240 is movably connected to the base 4000 and can contact and drive the base coupling member 4100. Rotation of the operating member rotating unit 4230 can directly or indirectly drive the operating member drive unit 4240 to move, thereby driving the base coupling member 4100.

It should be understood that the base connector 4100 used in the second embodiment can be identical in structure and operating principle to the base connector 4100 described in the first embodiment. Therefore, as shown in FIG. 67, the operating member drive 4240 in the second embodiment can adopt a structure similar to that of the operating member extension 4220 in the first embodiment.

For example, the operating member drive unit 4240 may be provided with an elongated drive unit drive groove 4240B (see FIG. 67), which is similar to the operating member drive groove 4220A in the first embodiment. It is used to cooperate with the engaging member drive pin 4120 (see FIG. 67) on the base engaging member 4100, so that when the operating member drive unit 4240 moves relative to the base 4000, the operating member drive groove 4240B drives the engaging member drive pin 4120 to slide within it. The sliding direction of the engaging member drive pin 4120 within the operating member drive groove 4240B will also be inclined to the movement direction of the operating member drive unit 4240. Therefore, the base engaging member 4100 will rotate or move, thereby realizing the movement of the base engaging member 4100 toward the non-engaged position.

For example, the operating element drive unit 4240 may be provided with a drive element elongated slot 4240C (see FIG. 67) extending along the front-rear direction of the base 4000, similar to the operating element elongated slot 4210A in the first embodiment, for cooperating with the base protrusion 4600 on the base 4000 (see FIGS. 43 and 44), thereby restricting the movement of the operating element drive unit 4240 relative to the base 4000.

The following describes an embodiment in which the rotation of the operating member rotating part 4230 directly drives the operating member driving part 4240 to move. In this embodiment, the operating member rotating part 4230 acts directly on the operating member driving part 4240.

To link the rotating part 4230 and the driving part 4240, as shown in Figure 69, the rotating part 4230 has an elongated rotating part linkage groove 4230A, and the driving part 4240 has an elongated driving part linkage groove 4240A. An operating member driving shaft 4260 passes through both the rotating part linkage groove 4230A and the driving part linkage groove 4240A simultaneously, allowing the rotating part 4230 to drive the driving part 4240 to move via the driving shaft 4260.

More specifically, when the operating member rotating part 4230 is rotated under the operation of the user, the rotating part linkage groove 4230A on the operating member rotating part 4230 will rotate accordingly, thereby driving the operating member drive shaft 4260 passing through it to move. Since the operating member drive shaft 4260 also passes through the drive unit linkage groove 4240A on the operating member drive unit 4240, when the moving operating member drive shaft 4260 abuts against one end of the drive unit linkage groove 4240A, the operating member drive shaft 4260 will drive the operating member drive unit 4240 to move. This allows the operating member rotating unit 4230 to drive the operating member drive unit 4240 to move via the operating member drive shaft 4260.

As shown in Figure 69, the carrier 1 may be equipped with a drive unit reset elastic member 4240D. This drive unit reset elastic member 4240D is configured to drive the operating member drive unit 4240 towards its initial position. This ensures that once the user ceases to operate the operating member rotating part 4230, the operating member drive unit 4240 will return to its initial position under the elastic force of the drive unit reset elastic member 4240D. Simultaneously, the operating member drive unit 4240 will then, via the operating member drive shaft 4260, drive the operating member rotating part 4230 back to its initial position.

The 4240D drive unit reset elastic component can utilize various suitable elastic components such as springs, torsion springs, and hydraulic rods.

It should be understood that, although in the embodiment shown in FIG. 69, the drive unit reset elastic element 4240D is configured to act directly on the operating member drive unit 4240, in other embodiments, the drive unit reset elastic element 4240D may also be configured to act directly on the operating member rotating part 4230, such that the drive unit reset elastic element 4240D drives the operating member rotating part 4230 back to its initial position, and the operating member rotating part 4230, in turn, drives the operating member drive unit 4240 back to its initial position via the operating member drive shaft 4260.

Furthermore, the drive unit reset elastic element 4240D is not necessary. The operating member rotation unit 4230 can be configured to return to its initial position under user operation, thereby driving the operating member drive unit 4240 back to its initial position via the operating member drive shaft 4260.

Next, an embodiment in which the rotating part 4230 indirectly drives the driving part 4240 to move will be described with reference to FIGS. 72 to 74. Unlike the embodiments described above with reference to FIGS. 66 to 71, in this embodiment, the rotating part 4230 indirectly acts on the driving part 4240.

As shown in Figures 72 and 74, the base operating member 4200 further includes an operating member linkage 4270, which is configured to transmit the rotation of the operating member rotating part 4230 to the operating member driving part 4240, thereby driving the operating member driving part 4240 to move.

Figures 72 and 74 illustrate one embodiment of the operating member linkage 4270, which is rotatably connected to the base 4000 and has a linkage contact end 4270A. The linkage contact end 4270A abuts against the operating member rotating part 4230, such that rotation of the operating member rotating part 4230 drives the operating member linkage 4270 to rotate.

To enable the operating member linkage 4270 to move in conjunction with the operating member drive 4240, the operating member linkage 4270 is further provided with an elongated linkage slot 4270B. A linkage drive shaft 4280 passes through both the linkage slot 4270B and the drive linkage slot 4240A simultaneously, allowing the operating member linkage 4270 to drive the operating member drive 4240 to move via the linkage drive shaft 4280.

More specifically, when the rotating part 4230 of the operating member rotates under the operation of the user, the connecting part contact end 4270A of the operating member linkage part 4270, which abuts against the rotating part 4230 of the operating member, moves due to the push of the rotating part 4230, thereby causing the operating member linkage part 4270 to rotate. As a result, the connecting part elongated groove 4270B on the operating member linkage part 4270 will rotate accordingly, thereby driving the connecting part drive shaft 4280 passing through it to move. Since the linkage drive shaft 4280 also passes through the drive linkage groove 4240A on the operating member drive unit 4240, when the moving linkage drive shaft 4280 abuts against one end of the drive linkage groove 4240A, the linkage drive shaft 4280 will drive the operating member drive unit 4240 to move. This achieves the following: the movement of the operating member rotating unit 4230 is first transmitted to the operating member linkage unit 4270, and then the operating member linkage unit 4270, with the aid of the linkage drive shaft 4280, drives the operating member drive unit 4240 to move.

To achieve rotation of the operating element linkage 4270, in one embodiment, as shown in Figures 72 and 74, the operating element linkage 4270 may include a linkage rotation shaft 4270C, around which the operating element linkage 4270 rotates.

It should be understood that the linkage rotation shaft 4270C can be integrated with the operating member linkage 4270, or it can be a separate component independent of the operating member linkage 4270. The base 4000 may have a shaft hole (not shown) for the linkage rotation shaft 4270C to rotate within it. Alternatively, the linkage rotation shaft 4270C can be integrated with the base 4000, and the operating member linkage 4270 may have a shaft hole for the linkage rotation shaft 4270C to rotate within it.

Furthermore, in the embodiment shown in Figure 74, the linkage slot 4270B is provided at the other end of the operating member linkage 4270 opposite to the linkage contact end 4270A. However, it should be understood that the linkage slot 4270B can be provided at other positions on the operating member linkage 4270, as long as it can transmit the movement of the operating member rotating part 4230.

Although one embodiment of the operating member linkage 4270 has been described above with reference to Figures 72 and 74, this disclosure is not limited thereto. The operating member linkage 4270 may adopt other structures. For example, the operating member linkage 4270 may be a flexible component such as a wire, thread, or rope, with one end connected to the operating member rotating part 4230 and the other end connected to the operating member driving part 4240, thereby enabling the operating member linkage 4270 to transmit the rotation of the operating member rotating part 4230 to the operating member driving part 4240, thereby driving the operating member driving part 4240 to move.

In the embodiment shown in Figure 74, the carrier 1 may also be equipped with a drive unit reset elastic member 4240D. The arrangement and function of the drive unit reset elastic member 4240D are the same as described above, and will not be repeated here.

Similar to the first embodiment, in the second embodiment of the base 4000, as shown in Figures 66 to 74, the base connector 4100 may include a front base connector 4100A and a rear base connector 4100B spaced apart along the front-rear direction of the base 4000. The front base connector 4100A is located at the front of the base 4000, and the rear base connector 4100B is located at the rear of the base 4000. Furthermore, the operating member drive unit 4240 may be configured to directly drive the rear base connector 4100B towards a non-engaged position, and simultaneously indirectly drive the front base connector 4100A towards a non-engaged position via a base linkage (not shown).

As shown in Figures 67, 70, 71 and 72, when the base connector 4100 can rotate around the connector pivot axis 4150 on the base 4000, in order to keep the base connector 4100 more stably in the engagement position, the base connector 4100 may be provided with a connector counterweight 4140, which is configured to make the base connector 4100 tend to rotate toward the engagement position. For example, the position of the coupling counterweight 4140 on the base coupling 4100 can be a certain distance from the coupling pivot axis 4150 in the front-rear direction of the carrier 1, such that the center of gravity of the base coupling 4100 is located between the coupling counterweight 4140 and the coupling pivot axis 4150 in the front-rear direction of the carrier 1. This facilitates the generation of a torque that causes the base coupling 4100 to pivot towards the coupling position.

In this disclosure, the counterweight 4140 of the connector can be any suitable counterweight component, such as a column or block, as long as its size and weight can match the base connector 4100.

Specifically, in the embodiment shown in Figure 70, the rear base connector 4100B is provided with a rear connector counterweight 4140B. The rear connector counterweight 4140B can be configured such that the center of gravity P2 of the rear base connector 4100B is located between the rear connector counterweight 4140B and the rear connector pivot axis 4150B in the longitudinal direction of the carrier 1. Therefore, the center of gravity P2 of the rear base connector 4100B will generate a torque that causes the rear base connector 4100B to pivot towards the engagement position.

In one embodiment, the distance X2 between the center of gravity P2 of the rear base connector 4100B and the centerline of the rear connector pivot 4150B in the longitudinal direction of the carrier 1 is equal to 4 mm.

In another embodiment, the center of gravity P2 of the rear base connector 4100B can be positioned substantially on the same horizontal plane I2 as the centerline of the rear connector pivot axis 4150B. For example, the rear connector counterweight 4140B can be positioned such that the center of gravity of the rear connector counterweight 4140B is on the same horizontal plane I2 as the centerline of the rear connector pivot axis 4150B. In this configuration, when the vehicle is in operation, in the event of sudden braking or acceleration due to a rear-end collision, the center of gravity P2 of the rear base connector 4100B will not generate a torque that would cause the rear base connector 4100B to rotate toward a non-engaged position due to these sudden events. This effectively prevents the rear base connector 4100B from accidentally disengaging from the rear vehicle connector 108B of the vehicle 1 (one of the vehicle connectors 108, see Figure 37B).

Alternatively, in the embodiment shown in FIG71, the front base connector 4100A is provided with a front connector counterweight 4140A. The front connector counterweight 4140A can be configured such that the center of gravity P1 of the front base connector 4100A is located between the front connector counterweight 4140A and the front connector pivot axis 4150A in the longitudinal direction of the carrier 1. Therefore, the center of gravity P1 of the front base connector 4100A will generate a torque that causes the front base connector 4100A to pivot towards the engagement position.

In one embodiment, the distance X1 between the center of gravity P1 of the front base connector 4100A and the centerline of the front connector pivot axis 4150A in the longitudinal direction of the carrier 1 is equal to 17 mm.

In another embodiment, the center of gravity P1 of the front base connector 4100A can be positioned substantially on the same horizontal plane I1 as the center line of the front connector pivot axis 4150A. For example, the front connector counterweight 4140A can be positioned such that the center of gravity of the front connector counterweight 4140A is on the same horizontal plane I1 as the center line of the front connector pivot axis 4150A. In this configuration, when the vehicle is in operation, in the event of sudden braking or acceleration due to a rear-end collision, the center of gravity P1 of the front base connector 4100A will not generate a torque that would cause the front base connector 4100A to rotate toward a non-engaged position due to these sudden events. This effectively prevents the front base connector 4100A from accidentally disengaging from the front vehicle connector 108A (one of the vehicle connectors 108, see Figure 37B) of the vehicle 1.

It should be understood that although the connector counterweight 4140 is described in the above embodiment as a second embodiment in conjunction with the base 4000, the connector counterweight 4140 can also be applied in the first embodiment of the base 4000.

Vehicle application device

Next, an embodiment of the vehicle application device 5000 according to this disclosure will be described with reference to Figures 75 to 83.

It should be noted that, in this document, the vehicle application device 5000 refers to a device that allows the vehicle 1 to be placed or used. Although the vehicle application device 5000 shown in the figures is a baby stroller, this disclosure is not limited to this. The vehicle application device 5000 according to this disclosure may also include, but is not limited to, a baby seat for carrying an infant, a stroller for carrying a child, a stroller for carrying items or animals, or a base that can be connected to a vehicle seat, etc.

Furthermore, although the vehicle 1 shown in the diagram is an infant carrier, this disclosure is not limited thereto. According to this disclosure, vehicle 1 can be used to carry a person, an animal, or articles, including but not limited to a sleeping box, a car seat, an animal carrier, or a cargo carrier.

The carrier 1 can have multiple embodiments. For example, a first embodiment of the carrier 1 has a pivotable anchor joint 20 (see Figure 77), a second embodiment of the carrier 1 has a retractable anchor joint 20 (see Figure 78), and a third embodiment of the carrier 1 does not have an anchor joint 20 (see Figure 79).

For ease of description, the following examples will use a stroller as the vehicle application device 5000 and a baby carrier as the vehicle 1.

Furthermore, this paper defines the direction the infant faces in the stroller 5000 as "front" and the direction they face away from as "back" (see Figures 75, 77 to 79). The left-right direction, perpendicular to the front-back direction, is defined as the lateral T of the stroller 5000 (see Figures 76, 80, and 81). Other forms of vehicle application devices 5000 may have structures similar to or different from the stroller.

To securely and reliably connect the infant carrier 1 to the stroller 5000, the stroller 5000 includes an application retainer that engages with the carrier retainer on the infant carrier 1, thereby allowing the infant carrier 1 to be positioned within the stroller 5000.

In the embodiments shown in Figures 75 to 81, the application retaining unit includes two lateral application retaining units 5100 disposed along the lateral direction T of the stroller 5000. Correspondingly, as shown in Figures 84 to 86, the carrier retaining unit of the infant carrier 1 includes two lateral carrier retaining units 1G that engage with the two lateral application retaining units 5100.

To achieve engagement between the application holding part and the carrier holding part, the lateral application holding part 5100 is provided with a recess 5110 (see Figures 76, 81, and 82), and the lateral carrier holding part 1G is provided with a protrusion 1G1 (see Figures 84 to 86). The recess 5110 and the protrusion 1G1 can engage.

In this case, because the distance between the two lateral application retaining parts 5100 is very close to the distance between the two lateral carrier retaining parts 1G (to ensure better engagement between the lateral application retaining parts 5100 and the lateral carrier retaining parts 1G), when the infant carrier 1 is placed in the stroller 5000, it is relatively difficult for the protrusion 1G1 of the lateral carrier retaining part 1G to enter the recess 5110 of the lateral application retaining part 5100.

To facilitate the insertion of the protrusion 1G1 into the recess 5110, in the embodiments shown in Figures 86 and 84, the protrusion 1G1 is configured to be operable to extend or retract from the infant carrier 1. As shown in Figure 86, when the protrusion 1G1 is extended from the infant carrier 1, i.e., in the extended position, the distance between the protrusions 1G1 on both sides of the infant carrier 1 is greater than the distance between the recesses 5110 on both sides of the stroller 5000, making it difficult for the infant carrier 1 to reach the position of connection with the stroller 5000. As shown in Figure 87, when the protrusions 1G1 are retracted into the infant carrier 1, i.e., in the retracted position, the distance between the protrusions 1G1 on both sides of the infant carrier 1 becomes smaller than the distance between the recesses 5110 on both sides of the stroller 5000. This allows the infant carrier 1 to easily reach the position where it is connected to the stroller 5000. Thus, when placing the infant carrier 1 into the stroller 5000, the user can first operate the protrusions 1G1 to retract the infant carrier 1, making it easy for the infant carrier 1 to reach the position where it is connected to the stroller 5000. Then, after aligning the protrusion 1G1 with the recess 5110, the protrusion 1G1 is manipulated to extend out of the infant carrier 1 and into the recess 5110, thereby easily completing the engagement between the lateral application retaining part 5100 and the lateral carrier retaining part 1G, thus holding the infant carrier 1 in the connected position with the stroller 5000.

In one embodiment, the protrusion 1G1 that can extend or retract from the infant carrier 1 can be a connecting post.

Of course, this disclosure is not limited to this.

The protrusion 1G1, which can extend or retract the infant carrier 1, can be implemented using other structures to achieve its extension and retraction. For example, a button (not shown) linked to the protrusion 1G1 can be provided in the infant carrier 1; pressing this button retracts the protrusion 1G1 into the infant carrier 1.

Furthermore, the lateral application holding part 5100 of the stroller 5000 may have a protrusion, and the lateral carrier holding part 1G of the infant carrier 1 may have a recess. Moreover, the lateral application holding part 5100 of the stroller 5000 may have a protrusion that can be operated to extend or retract the stroller 5000.

In addition to this convex-concave mating joint, this disclosure also allows for other joint methods, such as the mating of guide rails and guide grooves.

The two lateral application retainers 5100 can be part of the stroller 5000 or a separate component mounted on the stroller 5000.

In the embodiments shown in Figures 75 to 81, the lateral application retaining part 5100 is a separate component mounted on the stroller 5000. In this embodiment, the lateral application retaining part 5100, consisting of a separate component, includes a retaining part engaging end 5120 and a retaining part connecting end 5130.

As shown in Figure 82, the retaining part engagement end 5120 is provided with a recess 5110 for engaging with a protrusion 1G1 provided in the transverse carrier retaining part 1G.

The retaining connector 5130 can be connected to the rider 5200 of the stroller 5000 (see Figures 75 to 81).

More specifically, as shown in Figures 82 and 83, the retaining part connection end 5130 is sleeve-shaped and fits onto the stroller handlebar 5200.

To prevent the lateral application retaining part 5100 from sliding up and down along the rider 5200, a through hole (see Figure 82) can be formed at the connection between the rider 5200 and the retaining part connecting end 5130, and a screw or pin is driven through this through hole to prevent the retaining part connecting end 5130 from moving relative to the rider 5200.

Although the rider 5200 shown in the figure is the dismounting rider, this disclosure is not limited to this; the retaining connector 5130 can be fitted onto the mounting rider of the stroller. In other embodiments, the retaining connector 5130 can be connected to other parts of the stroller 5000, such as the seat.

By engaging the recesses 5110 on both sides of the stroller 5000 and the protrusions 1G1 on both sides of the infant carrier 1, a two-point connection can be achieved between the stroller 5000 and the infant carrier 1.

In this two-point connection configuration, the infant carrier 1 can be positioned forward-facing within the stroller 5000, meaning the baby's facing direction within the carrier 1 aligns with the forward direction of the stroller 5000, thus aligning the baby's field of vision with the caregiver's. Alternatively, the infant carrier 1 can be positioned rear-facing within the stroller 5000, meaning the baby's facing direction within the carrier 1 aligns with the rearward direction of the stroller 5000 (see Figures 77 to 79), allowing the caregiver easier observation of the baby's condition within the carrier 1.

Of course, this disclosure is not limited thereto. In one embodiment, the application retaining part may include two longitudinal application retaining parts (not shown) arranged along the front-rear direction of the stroller 5000. Correspondingly, the carrier retaining part of the infant car seat 1 may include two longitudinal carrier retaining parts (not shown) that engage with the two longitudinal application retaining parts.

In another embodiment, the application retainer may be a vertical support (not shown) disposed on the stroller 5000, and the carrier retainer may be a vertical slot (not shown) disposed in the infant carrier 1. The infant carrier 1 is positioned in the stroller 5000 through the engagement of the vertical support and the vertical slot.

In the aforementioned two-point connection configuration, to ensure the infant carrier 1 maintains its rear-facing balance after being placed in the stroller 5000, the two lateral carrier holding parts 1G on the infant carrier 1 can be positioned at the center of the infant carrier 1 in the rear-facing direction. That is, the two lateral carrier holding parts 1G can be positioned as close as possible to the center of gravity of the infant carrier 1 in the rear-facing direction to reduce the tendency of the infant carrier 1 to tip over in the rear-facing direction.

To ensure that the infant carrier 1 will not tip over in the front-to-back direction after being placed in the stroller 5000, the following solutions are also provided in this disclosure.

In the first embodiment, the recessed portion 5110 and the protruding portion 1G1 correspond in shape and size, and are configured such that the protruding portion 1G1 cannot rotate within the recessed portion 5110.

For example, the recess 5110 of the application retainer can have a quadrilateral opening (see FIG. 82), and the protrusion 1G1 of the carrier retainer is correspondingly a prism with a quadrilateral base (see FIGS. 84 and 85). Furthermore, their dimensions correspond; that is, the protrusion 1G1 of the carrier retainer is slightly smaller than the recess 5110 of the application retainer. Thus, when the protrusion 1G1 is inserted into the recess 5110, it cannot rotate within the recess 5110, thereby preventing the infant carrier 1 from tipping over relative to the stroller 5000 in the front-to-back direction.

Of course, this disclosure is not limited to this. The recessed portion 5110 of the application retaining part and the protruding portion 1G1 of the carrier retaining part can also be cylinders with various polygonal, elliptical, or other shaped bottom surfaces, as long as it can be ensured that the protruding portion 1G1 cannot rotate inside the recessed portion 5110.

In the second embodiment, the application holding part may include a longitudinal application holding part 5300, which is spaced apart from two transverse application holding parts 5100 along the longitudinal direction of the stroller 5000. Correspondingly, the carrier holding part includes a longitudinal carrier holding part 1H capable of engaging with the longitudinal application holding part 5300.

In the embodiments shown in Figures 77 to 80, the longitudinal application retaining part 5300 can be a stroller armrest, and the longitudinal carrier retaining part 1H can engage with the armrest 5300.

In one embodiment, the longitudinal carrier holding part 1H is configured to be operable between a connected position engaged with the longitudinal application holding part 5300 and a non-connected position disengaged from the longitudinal application holding part 5300.

In another embodiment, the longitudinal carrier holding part 1H, which can be operated to move between a connected position and a non-connected position, can be a connecting hook 3000 (see Figure 84).

Of course, this disclosure is not limited to this. The longitudinal application retaining unit 5300 can be other components on the stroller 5000, or it can be a separate component on the stroller 5000 as the longitudinal application retaining unit 5300.

Similarly, the longitudinal carrier holding part 1H can be any other component on the infant carrier 1, or it can be a separate component on the infant carrier 1 serving as the longitudinal carrier holding part 1H.

By engaging the recesses 5110 on both sides of the stroller 5000 with the protrusions 1G1 on both sides of the infant carrier 1, and by engaging the longitudinal application retaining part 5300 of the stroller 5000 with the longitudinal carrier retaining part 1H of the infant carrier 1, a three-point connection can be achieved between the stroller 5000 and the infant carrier 1, thus ensuring a more stable connection between the stroller 5000 and the infant carrier 1.

In this disclosure, either the first or second scheme described above may be used, or both may be used together.

Vehicle and vehicle application device assembly

The carrier 1, such as an infant carrier, can be used not only with a car seat but also with a stroller. For example, the stroller frame has a connecting component such as an adapter, and the carrier 1 has another connecting component that can be locked to that connecting component. Simultaneously, the carrier 1 needs to be equipped with a release mechanism, such as a release button, to release the two connecting components.

In one embodiment, the release method requires the user to bend over and continuously press the release button with both hands while lifting the vehicle 1 to detach it from the frame. This release method requires bending over and using both hands simultaneously to continuously press the release button while lifting the vehicle 1, making it cumbersome and inconvenient, thus negatively impacting the user experience.

This disclosure presents a connection assembly for the carrier 1 and the carrier application device, which simplifies and facilitates the assembly and disassembly of the carrier 1 and the carrier application device 5000.

The coupling assembly between the carrier 1 and the carrier application device according to this disclosure will now be described with reference to Figures 88 to 99.

As previously stated, the vehicle 1 according to this disclosure can be used to carry a person, an animal, or goods, including but not limited to infant carriers, sleeping boxes, car seats, animal carriers, or goods carriers. According to the vehicle application device, this refers to the device that enables the vehicle 1 to be placed or used, including but not limited to strollers carrying infants, baby seats, children's strollers, or strollers carrying goods or animals, or bases that can be connected to vehicle seats.

For ease of description, the embodiment shown in Figures 88 to 95 uses a baby carrier 1 with a pivot 100 as an example.

Furthermore, to show the connecting components more clearly, Figures 88 to 95 do not show the vehicle application device, but only the connecting components that can be mounted on the vehicle application device. However, it should be understood that the vehicle 1 can be detachably mounted on the vehicle application device via the connecting components.

As shown in Figures 88 to 95, the coupling assembly includes a first coupling member 600 and a second coupling member 700 that are capable of engaging (e.g., plugging and unplugging) and locking separately. One of the first coupling member 600 and the second coupling member 700 is disposed on the carrier 1, and the other is disposed on the carrier application device. Engagement and separation between the carrier 1 and the carrier application device are achieved through the engagement and separation of the first coupling member 600 and the second coupling member 700.

In the embodiments shown in Figures 88 to 95, the description takes the example of a first engaging member 600 disposed on the carrier 1 and a second engaging member 700 disposed on the carrier application device. However, it should be understood that the first engaging member 600 can be disposed on the carrier application device and the second engaging member 700 can be disposed on the carrier, which also allows the carrier 1 to be detachably mounted on the carrier application device.

The first engaging member 600 according to this disclosure may include a first member body 610, a first locking member 620, a first release button 630, and a first retaining member.

The first component body 610 is configured to accommodate a portion of the second engaging component 700. For example, the first component body 610 is an open cavity structure, thereby enabling engagement between the first engaging component 600 and the second engaging component 700 to ensure that the carrier 1 can be securely mounted on the carrier application device.

In one embodiment, as shown in Figure 88, a handle mount 1F1 for a handle 1F can be installed on the outer side of the first component body 610 to facilitate the user lifting the vehicle 1 via the handle 1F.

As shown in Figures 92A and 93A, the handle mounting base 1F1 and the first engaging member 600 can be fixed to the carrier 1 by sequentially passing a handle fixing member 1F3, such as a bolt or rivet, through the handle mounting base 1F1 and the first locking member 620 and fixing it to the carrier 1.

Additionally, as shown in Figure 88, a handle rotation button 1F2 may be provided on the handle mounting base 1F1. After pressing the handle rotation button 1F2, the user can adjust the rotation angle of the handle 1F relative to the carrier 1.

The first locking element 620 is used to lock and unlock between the first engaging member 600 and the second engaging member 700, thereby enabling locking and unlocking between the carrier 1 and the carrier application device. This ensures that the carrier 1 can be securely placed on the carrier application device and can be easily moved away.

Specifically, as shown in Figures 94 and 95A, the first locking member 620 is movably disposed on the first component body 610. Furthermore, the first locking member 620 has a locked position (see Figure 94A) for locking with the second locking member 710 disposed on the second engaging component 700, and an unlocked position (see Figure 94B) for releasing from the second locking member (710).

As shown in Figures 94A and 95A, the first component body 610 may have a notch communicating with the cavity structure therein, and the first locking member 620 is arranged facing this notch.

In the embodiments shown in Figures 94 and 95A, the second locking member 710 is a locking post disposed on the second engaging member 700, and the first locking member 620 is a locking hook connected to the first member body 610 and capable of hooking the locking post 710. For example, the second engaging member 700 has a connecting cavity inside for the locking hook 620 to be inserted into, and the locking post 710 can be disposed in the connecting cavity. When the first engaging member 600 and the second engaging member 700 are engaged, the locking hook 620 is inserted into the connecting cavity and hooked and locked with the locking post 710.

As shown in Figure 94A, when the locking hook (i.e., the first locking member) 620 is in the locked position, it engages the locking pin (i.e., the second locking member) 710, thereby locking the first engaging member 600 and the second engaging member 700 together.

As shown in Figure 95A, when the locking hook (i.e., the first locking member) 620 is in the unlocked position, it disengages from the locking pin (i.e., the second locking member) 710, thereby releasing the lock between the first engaging member 600 and the second engaging member 700. At this point, the user can move the carrier 1 away from the carrier application device by simply lifting the carrier 1 upwards using the handle 1F, thus separating the first engaging member 600 from the second engaging member 700.

To prevent accidental unlocking between the first engaging member 600 and the second engaging member 700, and to eliminate the need for the user to manually move the first locking member 620 towards the locked position, the first engaging member 600 may include a first locking member elastic body 640, configured to drive the first locking member 620 to the locked position, i.e., to tend towards the locked position.

Therefore, when the first engaging member 600 and the second engaging member 700 are engaged with each other, the first locking member 620 will move to the locked position and remain in the locked position under the elastic force of the first locking member elastic body 640, until the user applies a force to the first locking member 620, causing it to overcome the elastic force of the first locking member elastic body 640 and move to the unlocked position.

In the embodiments shown in Figures 94A and 95A, the first locking member 620 has a locking member mounting post 622 (see Figure 98), and the first locking member elastic body 640 is a torsion spring disposed around the locking member mounting post 622. A first end 641 (see Figure 99) of the torsion spring 640 abuts against the inner wall 623 (see Figure 98) of the first locking member 620, and a second end 642 (see Figure 99) abuts against the inner wall of the first component body 610.

As shown in Figure 98, the locking member mounting post 622 of the first locking member 620 has a through hole through which the aforementioned handle fixing member 1F3 passes, allowing the first locking member 620 to rotate around the handle fixing member 1F3.

Of course, this disclosure is not limited to this.

In other embodiments, the first locking element 640 may be a tension spring or a hydraulic cylinder, or other elastic component, as long as it can drive the first locking element 620 to the locked position.

Alternatively, the first engaging member 600 may omit the first locking member elastic body 640 and instead use other methods, such as pushing the first locking member 620 with the second member pushing part 720 of the second engaging member 700 (described later), to move the first locking member 620 to the locked position.

Alternatively, the first locking member 620 and the second locking member 710 can also employ other mating structures besides locking hooks and locking pins, such as a mating structure of locking pins and locking holes.

Furthermore, the movement of the first locking member 620 relative to the first component body 610 can also be a sliding motion, or a combination of rotational and sliding motions.

To facilitate the user applying force to the first locking member 620 to move it to the unlocked position, a first release button 630 is movably disposed in the first component body 610 and interacts with the first locking member 620, enabling the first release button 630 to drive the first locking member 620 to the unlocked position. That is, the first release button 630 and the first locking member 620 are linked. Therefore, the first release button 630 has a non-working position (see Figure 92A) that allows the first locking member 620 to be in the locked position and a working position (see Figure 93A) that allows the first locking member 620 to be in the unlocked position. When the first release button 630 is in the non-operating position, it does not exert any force on the first locking member 620, so the first locking member 620 can be held in the locked position by the elastic force of the first locking member elastic body 640. When the first release button 630 moves toward the operating position, it exerts a force on the first locking member 620, causing the first locking member 620 to overcome the elastic force of the first locking member elastic body 640 and move toward the locked position.

In the embodiments shown in Figures 91, 94A, 95A, 97, and 98, the first locking member 620 has a locking member push portion 621, and the first release button 630 has a button push portion 633. The button push portion 633 is configured to apply a force to the locking member push portion 621 to drive the first locking member 620 to the release position.

When the user presses down on the first release button 630, moving it towards the working position, the button push portion 633 applies force to the locking member push portion 621, causing the first locking member 620 to pivot to the release position (see FIG. 95A). This releases the first engaging member 600 and the second engaging member 700.

When the user stops pressing the first release button 630 downwards, if the first engaging member 600 includes a first locking member elastic body 640, the first locking member 620 will pivot to the locked position under the elastic force of the first locking member elastic body 640. Then, the locking member pushing portion 621 will apply a force to the button pushing portion 633, thereby driving the first release button 630 upwards to the non-operating position (see Figure 94A).

However, once the user stops pressing the first release button 630 downwards, the first locking member 620 will pivot to the locked position under the elastic force of the first locking member elastic body 640. This forces the user to simultaneously press the first release button 630 with both hands and then lift the vehicle 1 upwards to move the vehicle 1 away from the vehicle application device. This operation is complicated and inconvenient, affecting the user experience.

To address this issue, the first engagement member 600 according to this disclosure further includes a first retainer. The first retainer is configured to hold the first release button 630 in the working position, thereby holding the first locking member 620 in the released position.

In the embodiments shown in Figures 89 to 93A, the first component body 610 is provided with a first button mounting groove 611 in which a first release button 630 moves. The first button mounting groove 611 penetrates the first component body 610, so that a part of the first release button 630 can be exposed in the first component body 610 for the user to press or perform other operations, and the other part is inserted into the interior of the first component body 610 so as to abut against the first locking member 620. As shown in Figures 91, 94A, and 95A, the cross-sectional area of the portion of the first release button 630 that inserts into the first component body 610 can be larger than the cross-sectional area of the opening of the first button mounting slot 611. For example, the button push portion 633 can be formed into an enlarged flared shape to prevent the first release button 630 from accidentally disengaging from the first button mounting slot 611.

The first retaining member includes a mounting slot retaining portion 612 disposed within the first button mounting slot 611 and a button retaining portion 631 disposed within the first release button 630. The button retaining portion 631 is configured to be elastically blocked by the mounting slot retaining portion 612, thereby holding the first release button 630 in the working position.

In this document, "elastically blocking" means that when the force driving the first release button 630 to move in the first button mounting groove 611 increases to such an extent that at least one of the mounting groove retaining portion 612 and the button retaining portion 631, which are abutting each other, elastically retracts, the button retaining portion 631 can pass over the mounting groove retaining portion 612, thereby allowing the first release button 630 to move in the first button mounting groove 611. When the force exerted by the user to move the first release button 630 within the first button mounting slot 611 is insufficient to cause at least one of the mutually abutting mounting slot retaining portion 612 and the button retaining portion 631 to retract backward, the button retaining portion 631 cannot pass over the mounting slot retaining portion 612, thereby restricting the first release button 630 from moving within the first button mounting slot 611 to the desired position.

In the embodiments shown in Figures 90 and 91, the mounting groove retaining portion 612 is a limiting rib provided on the inner wall of the first button mounting groove 611, and the button retaining portion 631 is a retaining protrusion provided on the button elastic arm 632 of the first release button 630. The button elastic arm 632 of the first release button 630 allows the retaining protrusion 631, which serves as the button retaining portion, to elastically retract, thereby enabling the button retaining portion 631 to be elastically blocked by the mounting groove retaining portion 612.

However, this disclosure is not limited to this.

In other embodiments, the button retaining portion 631 may be a retaining protrusion disposed on the outer wall of the first release button 630, and the mounting slot retaining portion 612 may be a spring disposed on the inner wall of the first button mounting slot 611. This spring can abut against the retaining protrusion to restrict the first release button 630 from moving to the desired position within the first button mounting slot 611. However, when the force applied by the user to move the first release button 630 within the first button mounting slot 611 increases to a certain extent, the spring serving as the mounting slot retaining portion 612 will retract, causing the retaining protrusion to pass over the spring, thereby allowing the first release button 630 to move to the desired position within the first button mounting slot 611.

The operation of the first engaging member 600, including the first retainer, according to this disclosure will now be described.

As shown in Figure 95A, when the user is about to remove the carrier 1 from the carrier application device, they need to release the lock between the first engagement member 600 and the second engagement member 700 by applying a downward pressing force to the first release button 630, which is in the non-working position. The first release button 630 then moves downward, causing the button retainer 631 and the mounting slot retainer 612 to abut against each other. When the force applied by the user to the first release button 630 increases to the point that the button retainer 631 on the button elastic arm 632 springs back, the button retainer 631 can pass over the mounting slot retainer 612, thereby allowing the first release button 630 to move into the working position within the first button mounting slot 611. During this process, the downward-moving first release button 630 drives the first locking member 620 to overcome the elastic force of the first locking member elastic body 640 and move to the release position, thereby releasing the first engaging member 600 and the second engaging member 700.

Subsequently, when the user stops pressing down on the first release button 630, the elastic force of the first locking member 640 will drive the first locking member 620 toward the locked position. Then, the first locking member 620 will in turn drive the first release button 630 upward, causing the button holding part 631 and the mounting slot holding part 612 to abut against each other again. However, since the elastic force of the first locking member 640 is insufficient to allow the button retaining portion 631 on the button elastic arm 632 to elastically retract, the button retaining portion 631 cannot pass over the mounting slot retaining portion 612. This restricts the first release button 630 from remaining in the working position within the first button mounting slot 611, thus keeping the first locking member 620 in the released position, and maintaining the release between the first engaging member 600 and the second engaging member 700. In this way, the user does not need to continuously press the first release button 630; simply lifting the carrier 1 upwards disengages the first engaging member 600 from the second engaging member 700, allowing the carrier 1 to be removed from the carrier application device.

After removing the carrier 1 from the vehicle application device, the user needs to return the first locking member 620 to the locked position to prepare for the next placement and locking of the carrier 1 onto the vehicle application device. Since the first engaging member 600 and the second engaging member 700 are disengaged at this time, the first locking member 620 of the first engaging member 600 is exposed, allowing the user to manually move the first locking member 620 toward the locked position. This first locking member 620 then causes the first release button 630 to move upward, causing the button retainer 631 and the mounting slot retainer 612 to abut against each other. When the user applies a force sufficient to the first locking member 620 to cause the button retaining portion 631 on the button elastic arm 632 to spring backward, the button retaining portion 631 can pass over the mounting groove retaining portion 612, thereby allowing the first locking member 620 to move to the locked position. Simultaneously, the first release button 630 moves to the non-operating position within the first button mounting groove 611.

To prevent users from forgetting to operate the first locking member 620 to return it to the locked position after removing the vehicle 1 from the vehicle application device, this disclosure provides an auxiliary mechanism that can cause the first locking member 620 to return to the locked position without the user's explicit operation. In the embodiments shown in Figures 94A, 95A, and 96, the second engagement member 700 may be provided with a second member pushing portion 720, which is configured as a protrusion protruding from the inner wall of the second engagement member 700 toward the first locking member 620. This protrusion can act on the first locking member 620 to pivot to the locked position during the separation of the first engagement member 600 and the second engagement member 700 (i.e., during the removal of the vehicle 1 from the vehicle application device). During this process, the locking member push portion 621 of the first locking member 620 applies a force to the button push portion 633 of the first release button 630, causing the first locking member 620 to drive the first release button 630 back to the non-operating position.

Support structure and bearing device

In use, child safety seats or infant car seats need to be stably installed in vehicles, typically on the vehicle seats. To this end, some child safety seats or infant car seats have connection structures such as ISOFIX (standard fasteners) to attach them to the vehicle seats. However, due to differences in vehicle dimensions, after the connection structure is attached, there may be a gap between the child safety seat and the back of the vehicle seat, or between the infant car seat and the back of the vehicle seat. This can cause the child safety seat or infant car seat to wobble or tip over, creating a safety hazard.

To this end, this disclosure also proposes a jacking structure and a load-bearing device including the jacking structure.

Referring to Figures 100 to 102, a carrying device (first object J1, e.g., a vehicle) according to this application is described in general. In this embodiment, the first object J1 is an infant car seat, which can be installed in a vehicle seat (second object J2) such as a car seat, or can be used alone. In other embodiments, the first object J1 can be a child safety seat, a sleeping box, or other suitable form of carrying device or vehicle. This application can also be applied to structures with a base, wherein the support structure J100 can be provided in the base portion or the seat portion.

The first object J1 includes a seat body J300 and a support portion J400 disposed above the seat body J300. The seat body J300 is made of a relatively rigid material, such as plastic, and the support portion J400 is made of a relatively soft material, such as foam. In other embodiments, the seat body J300 and the support portion J400 may be a single component. At least one engaging structure J200 is disposed on the seat body J300 to engage the first object J1 to the second object J2, and at least one abutting structure J100 is disposed on the seat body J300 or the support portion J400 to fill the gap between the seat body J300 or the support portion J400 and the second object J2. More specifically, the abutment structure J100 is disposed at the upper rear end of the first object J1, close to the back of the second object J2, i.e., the vertical portion of the second object J2 shown in FIG. 101. Referring to FIG. 102, in this embodiment, two abutment structures J100 are respectively disposed on the lateral sides of the first object J1. In other embodiments, only one abutment structure J100 or more than two abutment structures J100 may be provided.

As shown in Figure 101, since the backrest of the second object J2 may have different angles or shapes, the gap between the seat body J300 or the support part J400 and the second object J2 is variable. The abutment structure J100 of this application can adapt to different gaps, abutting the first object J1 against the backrest of the second object J2, preventing swaying or tipping between the first object J1 and the second object J2, thereby improving the comfort and safety of the infant or child sitting on the first object J1.

It should be understood that although in this embodiment both the connecting structure J200 and the abutting structure J100 are located on the seat body J300, this application is not limited thereto. The abutting structure J100 may be located on the seat body J300 or the load-bearing part J400, and the connecting structure J200 may also be located on the seat body J300 or the load-bearing part J400.

The abutment structure J100 according to this application is described with reference to Figures 103 to 106. The abutment structure J100 includes a base J130, an abutment member J110, an biasing member J120, a first engaging member J140, and a second engaging member J150.

The base J130 is disposed on and integrally formed with the first object J1, meaning the base J130 is fixed relative to the first object J1. More specifically, in this embodiment, the base J130 is disposed at the upper rear end of the first object J1 to stably abut the abutment J110 against the second object J2. It should be understood that in other embodiments, the base J130 may also be a separate component assembled to the first object J1.

The base J130 includes an opening J131 and a beveled portion J132. The opening J131 is for the insertion and fixing of the first connector J140, and the opening J131 extends obliquely upwards axially. It should be understood that the axial direction of the opening J131 can also extend in other directions or be configured in other suitable forms, as long as it allows the first connector J140 to be inserted and fixed. In this embodiment, two first connectors J140 are provided, therefore two openings J131 are correspondingly provided on the base J130. In other embodiments, the number of openings J131 can vary according to the number of first connectors J140.

The beveled portion J132 extends in a direction substantially perpendicular to the first pivot axis JA1 (the pivot axis of the abutment member J110). More specifically, the beveled portion J132 extends from the opening J131 (or from a position between the two openings J131) toward the inner side of the support portion J400 of the first object J1, and gradually extends downward in the direction toward the inner side of the support portion J400, that is, gradually extends away from the abutment member J110. It should be understood that the beveled portion J132 can also be provided in other suitable forms, as long as it can serve as the abutment surface of the abutment portion J123.

The abutment J110 is mounted to the base J130 and is pivotable relative to the base J130 around the first pivot axis JA1 between a retracted position (Fig. 110) and an extended position (Fig. 107), abutting against the second object J2. It should be understood that the abutment J110 can abut against the second object J2 in the retracted position, the extended position, or any position between the retracted and extended positions.

The specific structure of the abutment member J110 is described with reference to Figures 105 to 108 and Figures 111A to 111C. The abutment member J110 is a plate-shaped member extending substantially perpendicular to the first pivot axis JA1, and includes an abutment portion J111, a pivot portion J112, a pivot hole J113, and a rib J114. More specifically, the abutment member J110 extends from the base J130 toward the second object J2. The two ends of the abutment member J110 are the pivot portion J112 and the abutment portion J111, respectively. The pivot portion J112 is pivotally connected to the base J130 via a first connecting member J140, and the abutment portion J111 is opposite to the pivot portion J112 and abuts against the second object J2.

In this embodiment, the abutment J111 is configured with a curved shape, meaning that after extending to the position furthest from the support portion J400, the abutment J111 extends in the opposite direction towards the support portion J400, thus forming an arc shape. In this way, the smooth surface of the abutment J111 is exposed to the outside, preventing accidental injury to the user. It should be understood that in other embodiments, the abutment J111 can also be configured with any suitable shape, as long as it can abut against the second object J2.

The pivoting part J112 has a pivot hole J113 whose axial direction is generally perpendicular to the first pivot axis JA1. The first connecting member J140 passes through the pivot hole J113 and is installed onto the base J130. The pivot hole J113 is configured to allow the abutment member J110 to pivot around the first pivot axis JA1. The pivot hole J113 includes a first wall J113a and a second wall J113b that are opposite each other.

The first engaging member J140 is inserted into the pivot hole J113 and fixed to the first object J1, thus allowing the abutment member J110 to pivot about the first pivot axis JA1 relative to the first engaging member J140 (i.e., relative to the first object J1 or the base J130 of the abutment structure J100). In this way, the pivoting function of the abutment member J110 is achieved through a simple structure. It should be understood that in other embodiments, the first engaging member J140 may be replaced by other pivoting structures, i.e., the abutment member J110 may also be connected to the first object J1 through a pivoting structure such as a pivot.

The first wall J113a and the second wall J113b extend approximately along a direction perpendicular to the first pivot axis JA1, forming an angle around the first pivot axis JA1. More specifically, the first wall J113a and the second wall J113b are farther apart from each other near the top portion J111 and closer together further away from the top portion J111. The first wall J113a and the second wall J113b can abut against the first connecting member J140 to define the pivot position of the top member J110 relative to the base J130. The first wall J113a is closer to the interior of the first object J1 than the second wall J113b, while the second wall J113b is closer to the exterior of the first object J1 than the first wall J113a. When the abutment member J110 rotates to the retracted and extended positions, the first engaging member J140 abuts against the first wall J113a and the second wall J113b respectively to prevent excessive rotation of the abutment member J110.

The specific structure of the biasing member J120 is described with reference to Figures 105 to 108. The biasing member J120 is mounted to the abutment member J110 and abuts against the base J130 to push the abutment member J110 toward the extended position. More specifically, the biasing member J120 is a plate-shaped part extending substantially perpendicular to the first pivot axis JA1, and includes a mounting portion J121 and an abutment portion J123 facing each other. The mounting portion J121 is connected to the abutment member J110 via a second connector J150. A mounting hole J122 is provided on the mounting portion J121. The second connector J150 passes through the mounting hole J122 to connect the mounting portion J121 to the abutment member J110. More specifically, the second coupling J150 is installed at the pivot point J112 of the abutment member J110. In this embodiment, the abutment structure J100 has two first couplings J140 along the first pivot axis JA1, and the biasing member J120 is installed between the two first couplings J140 and onto the abutment member J110.

The abutment portion J123 abuts against the base J130. More specifically, the abutment portion J123 is a sheet-like portion extending in a direction substantially perpendicular to the first pivot axis JA1, abutting against the inclined portion J132 of the base J130. The biasing member J120 can elastically deform to push the resisting member J110 towards its extended position; for example, both the mounting portion J121 and the abutment portion J123 can elastically deform, and the angle between them can also be changed.

Rib J114 is disposed along the inner surface of the abutment J110 between the abutment J111 and the pivot J112, thereby strengthening the abutment J110.

In this embodiment, the biasing element J120 achieves the effect of pushing the abutment element J110 towards the extended position with a simple structure. It should be understood that in other embodiments, the biasing element J120 may take other forms, such as a compression spring, a torsion spring, or other elastic material.

In this embodiment, the first connector J140 is a bolt inserted into the base J130 in a direction substantially perpendicular to the first pivot axis JA1. The second connector J150 is a bolt fixed to the abutment J110. It should be understood that the first connector J140 and the second connector J150 can be replaced by other common connectors.

The operation of the support structure J100 is described with reference to Figures 107 to 110.

In Figure 107, the abutment J110 is near its extended position, i.e., it is pivoted to its furthest point from the load-bearing part J400. At this point, the bending degree of the biasing member J120 is relatively small. The position of the abutment J110 shown in Figure 107 is suitable for the case where the gap between the first object J1 and the second object J2 is at its maximum.

As we transition from Figure 107 to Figure 110, the top part J111 gradually rotates towards the support part J400. In Figure 110, the top part J111 is closest to the retracted position. At this time, the bending degree of the biasing member J120 is at its maximum. The position of the top part J110 shown in Figure 110 is suitable for the case where the gap between the first object J1 and the second object J2 is minimized.

It should be understood that, depending on the size of the gap between the first object J1 and the second object J2, when the abutting member J110 abuts against the second object J2, the abutting member J110 may be in any position between Figures 108 and 110.

In summary, this application provides a supporting structure capable of automatically adjusting to fill the gap between a first object and a second object. This application also provides a load-bearing device including the supporting structure and the connecting structure.

The support structure of this application can stably hold a child safety seat or infant car seat against the vehicle seat, preventing the child safety seat from shaking or tipping over. Simultaneously, the support structure automatically adjusts its position according to the gap between the child safety seat and the vehicle seat, or the gap between the infant car seat and the vehicle seat, to accommodate different gap sizes, thereby adapting to different types and sizes of vehicle seats and improving the versatility of child safety seats or infant car seats.
