Description

Bracket assembly and electronic equipment accessory

Technical Field

The utility model relates to the technical field of 3C digital accessories, in particular to a bracket component and an electronic equipment accessory.

Background

In the related art of electronic equipment such as mobile phones, flat plates and the like, which are generally matched with a bracket assembly to acquire a supporting angle, a bracket is generally arranged in a containing groove designed by recessing a protective shell, so that the surface of the bracket is kept level with the surface of the protective shell, and the outward protruding of the bracket is avoided to influence the use of a user.

In the related unlocking type support protection shell technology, the support is locked or released through a locking structure, when the locking structure releases the locking of the support, undamped rotation (or small damping force) between the support and the protection shell is required to be ensured, otherwise, the support is difficult to be separated from the accommodating groove when the locking structure is released. Therefore, the traditional unlocking type support protective housing can be opened to a maximum angle (namely an angle when the support is opened to a certain angle and is mutually abutted with the protective housing) when the support is opened, and the product cannot meet different angle adjustment of the support because damping cannot be set between the support and the protective housing.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings.

In order that those skilled in the art will better understand the technical solutions of the present utility model, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present utility model and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the utility model described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

It should be further noted that the division of the embodiments in the present utility model is only for convenience of description, and should not be construed as a specific limitation, and features in the various embodiments may be combined and mutually referenced without contradiction.

Referring to fig. 1, an embodiment of the present utility model provides a bracket assembly 10 including a base 11, a support structure 12, and a rotating shaft structure 13. Wherein the rotating shaft structure 13 is rotatably connected to the base 11. The support structure 12 is rotatably connected to the shaft structure 13. The support structure 12 has a first angular position, a preset angular position and a second angular position with respect to the base 11. The support structure 12 may be locked in the first angular position or unlocked in the first angular position. The support structure 12 can rotate from the first angular position to the preset angular position along with the rotation of the rotating shaft structure 13 synchronously relative to the base 11. And the support structure 12 can rotate relative to the rotating shaft structure 13 from a preset angle position to a second angle position. In the process that the support structure rotates from the preset angle position to the second angle position, the rotating shaft structure 13 can stop rotating with the base 11. The rotational friction force between the rotating shaft structure 13 and the base 11 is smaller than the rotational friction force between the rotating shaft structure 13 and the supporting structure 12, wherein the rotational friction force can be understood as a damping force, that is, the rotating shaft structure 13 is more likely to rotate relative to the base 11, but is more difficult to rotate relative to the supporting structure 12. So that the support structure 12 can be firstly stationary relative to the rotating shaft structure 13 when the rotating shaft structure 13 rotates relative to the base 11, so as to rotate synchronously with the rotating shaft structure 13. When the rotation of the rotating shaft structure 13 and the base 11 is stopped, the supporting structure 12 rotates relative to the rotating shaft structure 13.

For example, the bracket assembly 10 further comprises a locking structure 113, the locking structure 113 being used to lock or unlock the support structure 12 in the first angular position. The locking structure 113 may lock the support structure 12 in the first angular position, for example, by magnetic attraction, snap-fit, or the like. The support structure 12 may be unlocked from the first angular position by disengaging the magnetic attraction or disengaging the snap connection when it is desired to open the support structure 12 for use.

For example, the angle between the support structure 12 and the base 11 at the first angular position is smaller than the angle between the support structure 12 and the base 11 at the preset angular position, and the angle between the support structure 12 and the base 11 at the second angular position is larger than the angle between the support structure and the base 11 at the preset angular position.

In use of the stand assembly 10, when the support structure 12 is in the closed position, the support structure 12 is received on the base 11, e.g., the support structure 12 is stacked on the base 11, at which point the angle between the support structure 12 and the base 11 is considered to be 0, at which point the support structure 12 is in the first angular position. I.e. the first angular position, the support structure 12 is in a stowed condition. The locking structure 113 is locked with the support structure 12. When it is desired to use the bracket assembly 10, the support structure 12 may be rotated from the first angular position to a predetermined angular position, for example, by rotating with the shaft structure 13 relative to the base 11.

In some embodiments, the bracket assembly 10 includes, for example, a pop-off structure 14, the pop-off structure 14 being configured to cause the support structure 12 to pop off from a first angular position to a preset angular position when the support structure 12 is unlocked from the first angular position. For example, when the support structure 12 is received on the base 11, the pop-up structure 14 is in a compressed state, and the predetermined angular position is the position of the rotating shaft structure 13 after the pop-up structure 14 is completely released. The supporting structure 12 is driven to synchronously rotate in the process that the rotating shaft structure 13 rotates to a preset angle position under the elastic action of the spring-open structure 14, so that the spring-open of the supporting structure 12 is realized, the supporting structure 12 is switched from a storage state to an open state, and the supporting effect can be realized. In some embodiments, the pop-up structure 14 may be omitted, and the user may manually open the support structure 12 to rotate from the first position to the preset angular position to switch from the storage state to the open state, and then manually pull the support structure 12 to rotate from the preset angular position to obtain a suitable support angle (i.e. the second angular position). In the process of rotating the support structure 12 from the preset angle position to the second angle position, for example, the rotation of the rotating shaft structure 13 and the base 11 can be stopped by setting a limiting structure, or the rotation of the rotating shaft structure 13 and the base 11 can be stopped by directly pressing the rotating shaft structure 13 by a user.

In the related art bracket assembly, in order to reduce the damping force between the rotating shaft and the bracket, a limit portion is generally required to be provided on the bracket to be abutted against a specific portion (such as a shell of the protective shell) after the bracket is sprung out, so that the bracket is kept at a specific angle, and therefore the bracket can only be supported at the specific angle, and cannot realize multi-angle support. In the bracket assembly 10 provided by the embodiment of the utility model, the supporting structure 12 can rotate relative to the base 11 in a limited manner through the rotating shaft structure 13, and the supporting structure 12 can rotate relative to the rotating shaft structure 13, so that a multi-angle adjusting effect can be realized, and more supporting angles are provided compared with the traditional bracket.

In some embodiments, referring to fig. 1-12, the shaft structure 13 comprises, for example, a first shaft assembly comprising a first shaft 131, the first shaft 131 being rotatably connected to the base 11, and the support structure 12 being in damped rotational connection with the first shaft 131. In this way, the supporting structure 12 and the rotating shaft structure 13 are relatively stationary during the rotation of the rotating shaft structure 13 from the first angular position to the preset angular position, and the supporting structure 12 is further rotatably connected to the rotating shaft structure 13, so that after the rotating shaft structure 13 is rotated around the rotating shaft structure 12 after the rotating shaft structure 13 is flicked, the angle of the supporting structure 12 relative to the base 11 is changed when the rotating shaft structure 13 is stationary relative to the base 11, and the angle adjusting function can be realized. In some embodiments, the support structure 12 and the rotating shaft structure 13 can be, for example, the support structure 12 has a second shaft sleeve, the first rotating shaft 131 penetrates the second shaft sleeve, and the diameter of the shaft hole of the second shaft sleeve is smaller than that of the first rotating shaft 131, so as to realize a damped rotating connection.

In some embodiments, referring to fig. 3, the first shaft assembly includes a first shaft 131 and a pusher 132 fixedly coupled to the first shaft 131, the pusher 132 being located between the support structure 12 and the base 11. The support structure 12 is rotatably connected to the first shaft 131. The pushing member 132 can rotate with the first rotating shaft 131 relative to the base 11 to push the supporting structure 12 to rotate from the first angular position to the preset angular position. The pushing member 132 abuts the support structure 12, for example during rotation of the support structure 12 from the first angular position to a preset angular position, thereby pushing the support structure 12 open. After the support structure 12 reaches the preset angle position, the support structure 12 can be manually adjusted to rotate relative to the rotating shaft structure 13, so as to realize support at other angles.

In some embodiments, a first stop 111 is provided on one of the base 11 and the first spindle assembly, and a stop 133 is provided on the other of the base 11 and the first spindle assembly. The stopper 133 is located at a side of the first stopper 111 facing away from the support structure 12. The distance between the stop member 133 and the first stop portion 111 may decrease as the support structure 12 rotates from the first angular position to the predetermined angular position, and the support structure 12 reaches the predetermined angular position when the stop member 133 abuts the first stop portion 111. Referring to fig. 5 and 6, the stopper 133 is provided on the first shaft assembly, and the first stopper 111 is provided on the base 11. The first angular position lower stop member 133 is spaced from the first stop portion 111, when the (first rotation shaft 131 of the) rotation shaft structure 13 rotates counterclockwise according to the orientation in fig. 6, the stop member 133 may approach the first stop portion 111, the distance between the stop member 133 and the first stop portion 111 decreases, and when the first rotation shaft 131 rotates until the stop member 133 abuts against the first stop portion 111, the first rotation shaft 131 is blocked by the first stop portion 111, so that the first rotation shaft 131 cannot continue to rotate counterclockwise to reach the preset angular position, as shown in fig. 7. Referring to fig. 8, the first shaft 131 of the first shaft assembly remains non-rotatable, and the support structure 12 may be rotated about the shaft structure 13 to a greater angle than the predetermined angular position to meet the user's demand for support. Or referring to fig. 13 and 14, the stopper 133 is provided at the base 11, the first stopper 111 is provided at the first shaft assembly, and the first stopper 111 is rotated near the stopper 133 when the shaft structure 13 is rotated clockwise according to the orientation shown in fig. 14, so that the distance between the stopper 133 and the first stopper 111 is reduced. Fig. 13 and 14 show the support structure 12 in a state of reaching a predetermined angular position.

Further, in some embodiments, a second stop 112 is also provided, the second stop 112 and the first stop 111 being provided on the base 11 or the first spindle assembly. In other words, the second stopper 112 is also provided on the base 11 when the first stopper 111 is provided on the base 11, and the second stopper 112 is also provided on the first shaft assembly when the first stopper 111 is provided on the first shaft assembly. The stopper 133 is located between the first stopper 111 and the second stopper 112. In the orientation shown in fig. 6, the second stop 112 is located below the stop 133. When the support structure 12 is in the position shown in fig. 8 and the support structure 12 needs to be stored, the support structure 12 and the rotating shaft structure 13 are relatively static, the support structure 12 rotates close to the base 11, the rotating shaft structure 13 rotates clockwise in the direction shown in fig. 6, the stop member 133 approaches to the second stop portion 112, when the stop member 133 rotates to abut against the second stop portion 112, the rotating shaft structure 13 cannot continue to rotate, and if the support structure 12 is not completely stored in the base 11, the support structure 12 can continue to rotate, so that the support structure 12 rotates relative to the rotating shaft structure 13 and is finally stored on the base 11.

The rotating shaft structure 13 specifically includes, for example, a first shaft sleeve 134, and the first rotating shaft 131 penetrates through the first shaft sleeve 134 and is fixedly connected with the first shaft sleeve 134. The pushing member 132 and the stopper 133 (or the first stopper 111) described in the foregoing embodiments are formed on the first boss 134, for example. For example, the first shaft housing 134 includes two first shaft housings 134 disposed along an axial direction of the first shaft 131, the stopper 133 protrudes from the two first shaft housings 134, and the pushing member 132 is connected between the two first shaft housings 134. In other embodiments, the stop 133 may also protrude radially outward from the surface of the first shaft 131 relative to the first shaft 131, i.e., the stop 133 may be a portion of the protrusion of the first shaft 131 without being disposed through the first sleeve 134. For another example, referring to fig. 4, a groove structure is formed on the first shaft sleeve 134, and two opposite sides of the groove structure are respectively used as the first stop portion 111 and the second stop portion 112, and the stop member 133 is disposed on the base 11.

The aforementioned pop-up structure 14 is specifically a torsion spring, and may be sleeved on the first rotating shaft 131. For example, when the number of the first sleeves 134 is two and the two first sleeves 134 are disposed at intervals along the axial direction of the first rotating shaft 131, the pop-up structure 14 is located between the two first sleeves 134, so that the pop-up structure 14 can be limited by the two first sleeves 134, and the pop-up structure 14 is prevented from sliding along the first rotating shaft 131.

In some embodiments, referring to the specific structure of the previous embodiments, when the support structure 12 is in the stowed state, the torsion spring is in the compressed state and the angle between the first leg and the second leg is small. When the torsion spring is sprung out, the included angle between the first pin and the second pin is increased, the second pin pushes the pushing piece 132, and the pushing piece 132 pushes the supporting structure 12, so that the supporting structure 12 is sprung out. The first pin of the torsion spring is fixed on the base 11, and the second pin is fixed on the rotating shaft structure 13 (specifically, the pushing member 132), so that the pushing member 132 is not pushed by the second pin when the torsion spring is in a completely released state after being sprung out, at this time, the rotating shaft structure 13 reaches a preset angle position, and when the supporting structure 12 continues to be manually rotated, the supporting structure 12 can rotate relative to the rotating shaft structure 13 to realize the support of other angles because the pushing member 132 is fixed by the torsion spring and cannot continue to rotate. By setting the rotation angle of the first rotation shaft 131 to be limited by the torsion spring, the preset angular position of the limiting support structure 12 can be realized instead of the stopper 133 and the first stopper 111.

In some embodiments, referring to fig. 4, the support structure 12 includes a support 121 and a first link 122, the first link 122 being rotatably coupled to the shaft structure 13. The first connecting piece 122 is provided with a first limiting portion 1221, the supporting piece 121 is provided with a second limiting portion 1211, and the first limiting portion 1221 and the second limiting portion 1211 are slidably connected. The supporting member 121 may be engaged with or separated from the locking structure 113 along with the sliding of the second limiting portion 1211 relative to the first limiting portion 1221, so that the supporting member 121 is locked or unlocked at the first angular position. That is, the support 121 is locked in the first angular position when the support 121 is engaged with the locking structure 113, and the support 121 is unlocked from the first angular position when the support 121 is disengaged from the locking structure 113.

The first and second limiting portions 1221 and 1211 may be, for example, a sliding connection between a slider and a slide rail, or may be another sliding connection between a slider and a slide groove. When the bracket assembly 10 is used, after the supporting member 121 is rotated with the first connecting member 122 to a state of being stacked on the base 11, the supporting member 121 can be manually pushed to slide relative to the first connecting member 122 and be engaged with the locking structure 113, so as to lock the supporting member 121 on the base 11. When the support structure 12 needs to be opened to realize the support function, the support piece 121 is pushed to slide relative to the first connecting piece 122 (opposite to the sliding direction during storage), so that the support piece 121 is separated from the locking structure 113, and then the whole support structure 12 is sprung out under the elastic action of the spring-out structure 14 to realize unlocking. The locking structure 113 may be disposed at an end of the base 11 away from the rotating shaft structure 13 as shown in fig. 2, for example, but other positions are also possible.

In some embodiments, one of the first stop 1221 and the second stop 1211 is a chute, and the other of the first stop 1221 and the second stop 1211 is a slider. Referring to fig. 4, the first stopper 1221 is a slider, and the second stopper 1211 is a chute.

The sliding distance of the sliding block in the sliding groove is larger than the clamping depth of the supporting piece 121 and the locking structure 113. Referring to fig. 9 and 10, the sliding distance of the slider in the sliding slot is L1, and the sliding distance of the slider in the sliding slot can be understood as the length of the sliding slot minus the length of the slider. The engagement depth between the supporting member 121 and the locking structure 113 is L2, and L1 is greater than or equal to L2. Fig. 9 shows a state in which the support 121 is engaged with the locking structure 113. According to the orientation shown in fig. 9, when the distance to slide the support 121 leftward is greater than L2, the engagement state of the lock structure 113 and the support 121 can be released. Thus, designing L1 to be greater than L2 ensures proper unlocking of the support 121.

In some embodiments, the device further comprises an elastic restoring structure 15, wherein one side of the elastic restoring structure 15 is connected with the supporting member 121, and the other side of the elastic restoring structure 15 is connected with the first connecting member 122. The elastic restoring structure 15 is, for example, a torsion spring, and both ends thereof are respectively fixed to the supporting member 121 and the first connecting member 122. When the support 121 is turned close to the base 11 for storage, as shown in fig. 9, continuing to press the support 121 downward when the support 121 is turned to be flush with the upper surface of the locking structure 113 will compress the elastic return structure 15, so that the support 121 slides to the left in fig. 9 and can be engaged into the groove below the locking structure 113, and after releasing the hand, the elastic return structure 15 returns to its elastic state to keep the support 121 engaged with the locking structure 113 without being separated at will. When unlocking is required, the supporting piece 121 can be manually pushed to overcome the elastic force of the elastic reset structure 15 to unlock the supporting piece 121 from the locking structure 113.

Referring to fig. 10, in some embodiments, a boss 1212 is formed on a side of the support member 121 adjacent to the first connecting member 122, a second limiting portion 1211 is disposed on the boss 1212, and a predetermined gap is formed between the first connecting member 122 and the support member 121. That is, as shown in fig. 10, the lower surface of the support 121 except for the boss 1212 portion forms a preset gap with the upper surface bracket of the first link 122. During assembly of the bracket assembly 10, the support member 121 and the first connector 122 are typically joined together by riveting, so that pressure will be applied to the first connector 122, and the provision of the boss 1212 creates a predetermined gap so that deformation of the first connector 122 during installation may be avoided.

In some embodiments, referring to fig. 15 to 18, in another embodiment of the present utility model, the bracket assembly 10 further includes a fixing portion fixedly connected to the base 11, and the rotating shaft structure 13 includes a rotating portion and a second rotating shaft assembly, wherein the rotating portion is rotatably connected to the base 11, and the second rotating shaft assembly is connected to the rotating portion.
