Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The inventor has long studied and found that in life, people often need to use various electronic products, and many electronic products need to be supported by a bracket so as to be convenient to use. For example, the mobile phone or the tablet computer is supported by a bracket, the user can conveniently watch the screen thereof. At present, when the support supports supported equipment in the prior art, the posture of the supported equipment is inconvenient to adjust, and adverse effects are brought to the use experience of a user. In order to solve this technical problem, the present application provides the following embodiments.

As shown in fig. 1 to 3, the stent device 1 described in the stent device embodiment of the present application includes a supporting mechanism 200, a first housing 110, a second housing 120, and a magnetic attraction assembly 130. The second housing 120 is rotatably connected to the first housing 110, and the second housing 120 is rotatable relative to the first housing 110 about a first reference axis L1. The magnetic assembly 130 is connected to the second housing 120 or the first housing 110. The magnetic assembly 130 serves to limit the supported device to the second housing 120 by magnetic force so that the supported device can rotate with the second housing 120 about the first reference axis L1 relative to the first housing 110. The support mechanism 200 is rotatably connected to the first housing 110, and the second housing 120 and the first housing 110 are rotatable together about the second reference axis L2 with respect to the support mechanism 200. The extending direction of the first reference axis L1 intersects with the extending direction of the second reference axis L2. That is, the first reference axis L1 is a rotation axis of the second housing 120 relative to the first housing 110, and the second reference axis L2 is a rotation axis of the first housing 110 relative to the supporting mechanism 200.

In some embodiments, the second housing 120 has a cylindrical outer side, and the first reference axis L1 is at a central axis position of the outer side of the second housing 120.

In some embodiments, the second housing 120 has a flat support area for the equipment to be supported to rest, and the second reference axis L2 is disposed parallel to the support area.

Further, the extending direction of the first reference axis L1 is perpendicular to the extending direction of the second reference axis L2.

Specifically, the support mechanism 200 may be used to support the first housing 110. The second housing 120 is rotatably connected with the first housing 110, and forms an accommodating space 160 with the first housing 110, and the second housing 120 is rotatable along a circumferential direction D1 of the first housing 110. The magnetic assembly 130 is disposed in the accommodating space 160 and connected to the second housing 120 or the first housing 110. The magnetic attraction assembly 130 is used for attracting the supported device to the second housing 120, so that the supported device can rotate with the second housing 120 along the circumferential direction D1 of the first housing 110 relative to the first housing 110. The magnetic attraction assembly 130 is used for attracting the supported device to a side of the second housing 120 facing away from the accommodating space 160.

By forming the accommodating space 160, the second housing 120 and the first housing 110 can protect and shield the magnetic assembly 130, which is beneficial to improving the structural stability and the aesthetic degree of the bracket device 1.

By supporting the first housing 110 and the second housing 120 with the supporting mechanism 200, it is advantageous for the second housing 120 to maintain its posture stable in carrying the supported device. Further, the support mechanism 200 may be used to raise the first housing 110 and the second housing 120 such that the first housing 110 and the second housing 120 and the supported device are spaced from the placement surface of the rack apparatus 1, facilitating rotation of the second housing 120 and the supported device relative to the first housing 110.

The supported device sometimes needs to adjust its posture while being supported. For example, the supported device may be a mobile phone or a tablet computer, and the posture of the mobile phone or the tablet computer display screen may be adjusted by rotating the supported device relative to the first housing 110, so that the mobile phone or the tablet computer can be switched between the landscape screen and the portrait screen. For another example, the supported device may be a cell phone or tablet computer, which may be tilted by rotating the supported device relative to the first housing 110.

Through setting the second casing 120 and the first casing 110 to be rotationally connected, when the user adjusts the gesture of supported equipment along the circumference D1 of the first casing 110, the second casing 120 and the supported equipment can rotate synchronously, so that sliding friction between the second casing 120 and the supported equipment can be avoided, or sliding friction between the second casing 120 and the supported equipment can be reduced, the rotating smoothness of the supported equipment can be improved, and the hand feeling of the user can be improved.

By providing the support mechanism 200 in rotational connection with the first housing 110, the degree of freedom of movement of the second housing 120 can be increased, thereby increasing the degree of freedom of movement of the supported device, facilitating adjustment of the posture of the supported device. Further, the second reference axis L2 is parallel or approximately parallel to the horizontal plane when the stand device 1 is in operation, so that an adjustment of the pitch angle of the supported equipment can be achieved. For example, when the supported device is a mobile phone or a tablet computer, the user can conveniently watch the mobile phone or the tablet computer by adjusting the pitching angle of the mobile phone or the tablet computer.

Optionally, the magnetic attraction assembly 130 comprises an annular arrangement of magnets. In some embodiments, the magnetic attraction assembly 130 may include an electromagnet.

Alternatively, as shown in fig. 2 and 3, the magnet assembly 130 includes a plurality of magnets arranged along the circumferential direction D1 of the first housing 110. Furthermore, the multiple magnets are spliced to form an annular structure with a fracture, so that the installation is convenient, and the installation specification is met.

Alternatively, as shown in fig. 1 and 2 to 5, the magnetic assembly 130 is connected to the second housing 120, so that the supported device and the magnetic assembly 130, the second housing 120 can rotate together about the first reference axis L1 relative to the first housing 110. Further, the supported device, the magnetic attraction assembly 130 and the second housing 120 can rotate together with respect to the first housing 110 along the circumferential direction D1 of the first housing 110.

By the arrangement, when the user adjusts the posture of the supported device along the circumferential direction D1 of the first shell 110, the second shell 120, the magnetic attraction component 130 and the supported device can synchronously rotate, so that sliding friction between the second shell 120 and the supported device can be avoided, or sliding friction between the second shell 120 and the supported device can be reduced, meanwhile, the resistance of the magnetic attraction component 130 to the rotation of the supported device is reduced, the rotation smoothness of the supported device is improved, and the force applied by the user is reduced.

In some embodiments, the magnetic attraction assembly 130 is removably coupled with the second housing 120. In other embodiments, the magnetic assembly 130 is fixedly connected to the second housing 120, such as by glue.

Alternatively, as shown in fig. 1, 6 to 8, the magnet assembly 130 is connected to the first housing 110 such that the supported device and the second housing 120 are rotatable together about the first reference axis L1 relative to the first housing 110 and the magnet assembly 130. Further, the supported device and the second housing 120 can rotate together along the circumferential direction D1 of the first housing 110 relative to the first housing 110 and the magnetic attraction assembly 130.

In this way, when the user adjusts the posture of the supported device along the circumferential direction D1 of the first housing 110, there may be no sliding friction between the second housing 120 and the supported device, or sliding friction between the second housing 120 and the supported device may be reduced, which is advantageous for improving the rotation smoothness of the supported device.

Specifically, the sliding friction refers to the friction force between the second housing 120 and the supported device when the two slide relatively, and the friction force between the second housing 120 and the supported device when the two are fixed relatively is static friction force. In some embodiments, the second housing 120 has a strong magnetic attraction force to the supported device, or a large friction coefficient between the second housing 120 and the supported device, and when the user adjusts the posture of the supported device along the circumferential direction D1 of the first housing 110, there is no sliding friction between the second housing 120 and the supported device, that is, the second housing 120 and the supported device rotate completely in synchronization. In other embodiments, the magnetic attraction force of the second housing 120 to the supported device is weak, or the friction coefficient between the second housing 120 and the supported device is small, and when the user adjusts the posture of the supported device along the circumferential direction D1 of the first housing 110, sliding friction exists between the second housing 120 and the supported device, that is, the second housing 120 and the supported device do not rotate completely synchronously.

In some embodiments, the magnetic attraction assembly 130 is removably coupled with the first housing 110. In other embodiments, the magnetic assembly 130 is fixedly coupled to the first housing 110, such as by glue.

By the arrangement, the size of the first casing 110 is reduced, and the size of the second casing 120 is increased, so that on one hand, the first casing 110 is not easy to see from one side of the bracket device 1, which adsorbs supported equipment, due to shielding of the second casing 120, and on the other hand, the appearance aesthetic property is improved, and on the other hand, the area of the surface of the first casing 110, in which the supported equipment is placed, is increased.

Alternatively, as shown in fig. 2 to 4, a bearing 151 is provided between the second housing 120 and the first housing 110. The first housing 110 includes an inner housing 113 and an outer housing 114. The second housing 120 and the inner housing 113 enclose an accommodating space 160. The outer casing 114 is located at the periphery of the inner casing 113, an installation space 115 is formed between the outer casing 114 and the inner casing 113, the bearing 151 is arranged in the installation space 115 and sleeved at the periphery of the inner casing 113, and the second casing 120 extends into the installation space 115 and abuts against the outer ring of the bearing 151.

By arranging the bearing 151 in the installation space 115, the outer housing 114 can shield and protect the bearing 151, which is beneficial to keeping the bearing 151 in a stable assembly relationship with the inner housing 113 and the second housing 120, and improving the structural stability and the appearance aesthetic degree.

Alternatively, as shown in fig. 2 to 4, the outer circumference of the inner housing 113 has a mounting step 1162, and the bearing 151 may be mounted on the mounting step 1162 to facilitate mounting of the bearing 151.

The supported device may be located outside of the upper cover 124. The other end of the middle frame 125 can extend into the installation space 115 to abut against the outer ring of the bearing 151. This arrangement facilitates assembly of the stent device 1. In some embodiments, the magnetic attraction assembly 130 may be secured to the upper cover 124.

Optionally, the upper cover 124 and the middle frame 125 are connected by glue or by snap-fit connection.

That is, the second housing 120 may conceal the first housing 110 at the front 102 of the stand device 1 such that the seam 105 between the second housing 120 and the first housing 110 is located at the back 103 or the peripheral side 104.

The seam 105 between the second housing 120 and the first housing 110 refers to the seam 105 at the interface of the second housing 120 and the first housing 110. For example, the seam 105 between the second housing 120 and the first housing 110 on the outer surface of the stent device 1 is the seam 105 between the middle frame 125 and the first housing 110. Further, the seam 105 between the second housing 120 and the first housing 110 on the outer surface of the stent device 1 is the seam 105 between the middle frame 125 and the outer housing 114.

For another example, the elastic protruding member 106 is disposed on the outer ring of the middle frame 125, and the plurality of fastening grooves 107 are disposed on the inner surface of the outer housing 114.

By providing the elastic protruding member 106 and the locking groove 107, the second housing 120 and the first housing 110 can be limited to rotate relatively to a certain extent, so that the stability of the posture of the supported device can be maintained. When the second housing 120 is stressed, the second housing 120 rotates relative to the first housing 110, and the elastic protruding member 106 can be disengaged from the original fastening groove 107 to allow the second housing 120 to rotate relative to the first housing 110, and as the second housing 120 rotates relative to the first housing 110, the elastic protruding member 106 continuously snaps into the new fastening groove 107 until the second housing 120 and the first housing 110 stop rotating relative to each other.

Alternatively, the resilient protrusion 106 is a spring needle. Or the elastic protruding piece 106 is a plastic, silica gel or rubber component with elasticity, and is connected with the second housing 120 or the first housing 110 through an elastic arm, and is deformed by the elastic arm to be disengaged from or clamped into the buckling groove 107. In some embodiments, the resilient protrusions 106 are formed as a corrugated sheet of metal that, when bent, creates a deformation space that allows the sheet of metal to deform to disengage or snap into the snap grooves 107.

In some embodiments, the second housing 120 and the first housing 110 may be provided with a limiting structure to limit the relative rotation angle of the second housing 120 and the first housing 110 within a certain range. In other embodiments, the second housing 120 and the first housing 110 may not have a limiting structure, so as to allow the second housing 120 and the first housing 110 to rotate one or more times.

In some embodiments, the second housing 120 and the first housing 110 may be rotatably coupled via threads.

Alternatively, the outer peripheral surface of the first housing 110 is approximately a part of a sphere, and the supporting mechanism 200 is connected to the central position of the outer peripheral surface of the first housing 110, and the central position of the outer peripheral surface of the first housing 110 is protruded outwards, so that the probability of mutual interference during the relative rotation of the supporting mechanism 200 and the first housing 110 can be reduced.

Alternatively, as shown in fig. 1 to 3, the supporting mechanism 200 includes a supporting rod 220 and a base 210 connected, and the supporting rod 220 is rotatably connected with the first housing 110.

Optionally, the base 210 and the support rod 220 are rotatably coupled. The support bar 220 drives the first housing 110 to approach or depart from the base 210 by rotating relative to the base 210. So configured, the support mechanism 200 can be folded to facilitate storage of the rack apparatus 1.

Alternatively, as shown in FIG. 1, the support rod 220 may rotate relative to the base 210 about a third reference axis L3. The extending direction of the third reference axis L3 is perpendicular to the height direction of the supporting mechanism 200.

Alternatively, as shown in fig. 1, the base 210 includes a first base and a second base rotatably connected, and the first base is rotatable relative to the second base about a fourth reference axis L4. The fourth reference axis L4 is a rotation axis of the first housing relative to the second housing. Further, the fourth reference axis L4 intersects the second reference axis L2. For example, the third reference axis L3 extends along the height direction of the support mechanism 200, and the second reference axis L2 is perpendicular to the height direction of the support mechanism 200. This arrangement is advantageous in increasing the freedom of movement of the supported device. In some embodiments, the first and second housings are rotatable relative to one another at least one revolution to enable 360 ° rotation of the supported device about the fourth reference axis L4.

Optionally, the support rod 220 is configured to be telescopic or foldable, and the support rod 220 can adjust its height size by telescopic movement or folding movement, so as to facilitate storage. For example, the support bar 220 includes a first sub-bar body and a second sub-bar body rotatably connected, and the first sub-bar body and the second sub-bar body can be folded or unfolded by rotating the first sub-bar body and the second sub-bar body relative to each other.

In some embodiments, the support bar 220 may include two bars or more bars arranged side by side. In some embodiments, the cross-sectional shape of the support rod 220 is circular or rectangular.

Alternatively, as shown in fig. 1 to 3, the supporting mechanism 200 is provided with a ball portion 201, the first housing 110 is provided with a connecting slot 117, and an elastic member 118 is disposed in the connecting slot 117, and the ball portion 201 rotatably extends into the connecting slot 117 and elastically abuts against the elastic member 118.

When the supporting mechanism 200 and the first housing 110 rotate relatively, the ball portion 201 can rotate in the connecting slot 117 and slide relative to the elastic member 118. The ball portion 201 can be locked into the connecting groove 117, so that the supporting mechanism 200 can be prevented from being separated from the first housing 110, and the first housing 110 can shield the ball portion 201 to improve the appearance. By elastically abutting the ball portion 201 against the elastic member 118, the rotational resistance of the ball portion 201 in the connecting groove 117 can be increased, and the ball portion 201 is prevented from being deviated from the working position due to loosening.

Alternatively, the elastic member 118 constitutes a bottom surface of the connection groove 117. Further, the elastic member 118 is a plastic member, a silicone member, or a rubber member.

Alternatively, as shown in fig. 1 to 3, the elastic member 118 has a first semi-cylindrical surface 119, the ball portion 201 has a second semi-cylindrical surface 202 abutting against the first semi-cylindrical surface 119, and both the generatrix extending direction of the first semi-cylindrical surface 119 and the generatrix extending direction of the second semi-cylindrical surface 202 are parallel to the second reference axis L2. Wherein the directions of generatrix extension of the first and second semi-cylindrical surfaces 119 and 202 are both parallel to the second reference axis L2 also includes that the directions of generatrix extension of the first and second semi-cylindrical surfaces 119 and 202 may also be approximately parallel to the second reference axis L2. Further, the second reference axis L2 is a central axis of the first semi-cylindrical surface 119. The central axes of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 are collinear.

So configured, the support mechanism 200 and the first housing 110 can be allowed to relatively rotate around the second reference axis L2 so as to adjust the posture of the supported device, and the support mechanism 200 and the first housing 110 can be limited to relatively move along the second reference axis L2, so that the support stability of the support mechanism 200 to the supported device can be maintained.

Optionally, the radian of the second semi-cylindrical surface 202 is matched with that of the first semi-cylindrical surface 119, so that the fit degree of the second semi-cylindrical surface 202 and the first semi-cylindrical surface 119 can be improved, and the elastic element 118 is beneficial to stably abutting against the ball head 201.

Alternatively, as shown in fig. 1 and 9, one of the support mechanism 200 and the first housing 110 is provided with a connection shaft section 204, and the other of the support mechanism 200 and the first housing 110 is provided with a connection hole 203, and the connection shaft section 204 is inserted into the connection hole 203 and is interference-fitted with the connection hole 203. Further, the connection shaft section 204 and the connection hole 203 are made of metal to improve strength and service life.

So configured, the support mechanism 200 and the first housing 110 can be allowed to relatively rotate about the second reference axis L2 when stressed so as to adjust the posture of the supported device, and the relative movement of the support mechanism 200 and the first housing 110 can be limited to a certain extent by increasing the friction force through the interference fit of the connecting shaft segment 204 and the connecting hole 203, which is beneficial to the support stability of the support mechanism 200 to the supported device.

In some embodiments, as shown in fig. 9, the first housing 110 is provided with a connection shaft section 204, and the support mechanism 200 is provided with a connection hole 203. The connecting shaft section 204 may include a post 2041 and a connecting piece 2042, wherein one end of the connecting piece 2042 is disposed around the post 2041 and located in the connecting hole 203 with the post 2041, the first housing 110 is provided with a connecting slot 117, a side wall of the connecting hole 203 is provided with a relief port 2031 and is communicated with the connecting slot 117 through the relief port 2031, and the other end of the connecting piece 2042 movably extends into the connecting slot 117 through the relief port 2031 and is fixed in the connecting slot 117. So configured, the connection shaft section 204 is allowed to rotate within the connection hole 203, which can facilitate the fitting connection of the support mechanism 200 with the first housing 110.

In summary, in this embodiment, when the user adjusts the posture of the supported device along the circumferential direction D1 of the first housing 110, the second housing 120 and the supported device may rotate synchronously, so that sliding friction may not exist between the second housing 120 and the supported device, which is favorable for improving the rotation smoothness of the supported device, and improving the hand feeling of the user, for example, the supported device may be a mobile phone or a tablet computer.
