[0056] The support with the rotating mechanism can be used to support electronic devices such as mobile phones, tablets, cameras, etc., change the use posture of the electronic devices, and improve the use convenience of the electronic devices in various scenarios.

[0057] The present disclosure provides a support. Figure 1 is a partial perspective structural schematic view of a device support in an exemplary embodiment of the present disclosure, Figure 2 is a perspective structural schematic view of a ball head seat of a device support in an exemplary embodiment of the present disclosure, Figure 3 is a structural schematic view of a connecting ball head of a device support in an exemplary embodiment of the present disclosure, as Figures 1-3 As shown in the figure, the rotating mechanism 14 includes a connecting ball head 142 and a ball head seat 141, the connecting ball head 142 is rotationally assembled in the ball head seat 141, one of the connecting ball head 142 and the ball head seat 141 is provided with a first limiting structure surrounding a limiting space 1413, and the other of the connecting ball head 142 and the ball head seat 141 is provided with a second limiting structure 1422. The second limiting structure 1422 is movably matched with the first limiting structure, so that the second limiting structure 1422 moves in the limiting space 1413 with the relative rotation of the connecting ball head 142 and the ball head seat 141.

[0058] The present disclosure further provides a support, which includes a base 113, a device matching part 111, and the above-mentioned rotating mechanism 14. The rotating mechanism 14 includes a ball head seat 141 and a connecting ball head 142, one of the ball head seat 141 and the connecting ball head 142 is fixedly connected with the base 113, and the other of the ball head seat 141 and the connecting ball head 142 is fixedly connected with the device matching part 111.

[0059] In the above embodiment, the connecting ball head 142 of the rotating mechanism 14 is rotatably assembled with the ball head seat 141, one of the connecting ball head 142 and the ball head seat 141 is provided with a first limiting structure surrounding a limiting space 1413, and the other is provided with a second limiting structure 1422, which is movably matched with the first limiting structure. The second limiting structure 1422 moves in the limiting space 1413 with the relative rotation of the connecting ball head 142 and the ball head seat 141, which does not affect the fixed-point rotation between the connecting ball head 142 and the ball head seat 141, and avoids the interference of the unlimited rotation of the connecting ball head 142 in the ball head seat 141 to the external wires and structures, thereby improving the use reliability of the support 1.

[0060] In some embodiments, the side wall of the ball head seat 141 surrounds a rotating space accommodating the connecting ball head 142, the first limiting structure includes at least one notch 1412 provided on the side wall, and the second limiting structure 1422 includes at least one protrusion provided on the surface of the connecting ball head 142, which moves in the limiting space 1413 surrounded by the notch 1412. The limiting space 1413 is formed by the notch 1412, and the protrusion provided on the surface of the connecting ball head 142 moves in the notch 1412, which helps to simplify the structure of the rotating mechanism 14 and reduce the improvement cost. For example, the above-mentioned notch 1412 can form an opening at the edge of the side wall, and the rotation angle of the connecting ball head 142 to the left and right can be limited to less than 50° through the above-mentioned notch 1412, and the pitch angle is not limited.

[0061] In some other embodiments, the side wall of the ball head seat 141 surrounds a rotating space accommodating the connecting ball head 142, the first limiting structure includes a recess provided on the outer surface 1421 of the connecting ball head 142, and the second limiting structure 1422 includes a protrusion provided on the inner surface of the side wall.

[0062] In some other embodiments, the first limiting structure includes a recess provided on the inner surface of the side wall, and the second limiting structure includes a protrusion provided on the outer surface 1421 of the connecting ball head 142.

[0063] The above-mentioned protrusion moves in the limiting space 1413 formed by the recess. The movement of the protrusion in the limiting space 1413 formed by the recess can simplify the structure and improve the overall aesthetics of the rotating mechanism 14.

[0064] In some embodiments, the outer surface 1421 of the connecting ball head 142 can be provided with both protrusions and recesses, and the inner surface of the side wall of the ball head seat 141 can be provided with both protrusions and recesses. The protrusion located on the outer surface 1421 of the connecting ball head 142 cooperates with the limiting space 1413 formed by the recess located on the inner surface of the side wall of the ball head seat 141. The protrusion located on the inner surface of the side wall of the ball head seat 141 cooperates with the limiting space 1413 formed by the recess located on the outer surface 1421 of the connecting ball head 142.

[0065] In the above embodiment, a pair of first limiting structures can be arranged on one of the connecting ball head 142 and the ball head seat 141, and a pair of second limiting structures 1422 can be arranged on the other one, so as to improve the limiting cooperation reliability of the connecting ball head 142 and the ball head seat 141. For example, a pair of notches 1412 can be arranged on opposite sides of the ball head seat 141, and a pair of protrusions can be arranged on the outer surface 1421 of the connecting ball head 142.

[0066] It should be noted that the protrusions can be circular, rectangular or irregular in shape. The limiting space 1413 formed by the first limiting structure can be circular, rectangular or irregular in shape. The shapes and sizes of the limiting space 1413 and the second limiting structure 1422 can determine the relative rotation range of the connecting ball head 142 and the ball head seat 141.

[0067] In some embodiments, the rotating mechanism 14 further comprises a locking member 143, which is sleeved on the outside of the ball head seat 141 and is in locking cooperation with the ball head seat 141, so as to improve the rotating cooperation reliability and structural reliability of the ball head seat 141 and the connecting ball head 142.

[0068] In some embodiments, the ball head seat 141 is externally provided with external threads, and the locking member 143 is internally provided with internal threads facing the inner wall of the ball head seat 141, and the external threads and the internal threads are in fastening cooperation, so as to improve the fastening convenience.

[0069] In some embodiments, the ball head seat 141 comprises a side wall and a top structure, the top structure is located at one end of the side wall, the side wall encloses a rotating space for accommodating the connecting ball head 142, and the top structure is fixedly connected with an external structure to realize the installation of the ball head seat 141.

[0070] In some embodiments, the outer wall of the locking member 143 opposite to the connecting ball head 142 is provided with at least one boss structure 1431, so as to facilitate the force exertion when rotating and tightening the locking member 143, and improve the tightening operation experience. The side surface of the boss structure 1431 connected with the outer wall of the locking member 143 can be an inclined surface or an arc surface, so as to further improve the tightening operation experience and overall aesthetics.

[0071] In some embodiments, the rotating mechanism 14 further comprises a damping member 144, which is fixedly assembled in the rotating space enclosed by the inner surface of the ball head seat 141, at least a part of the connecting ball head 142 is assembled in the rotating space, and the damping member 144 is arranged between the connecting ball head 142 and the inner surface of the ball head seat 141, so as to provide damping when the connecting ball head 142 rotates, and improve the operation feeling.

[0072] The connecting ball head 142 can include a top, a bottom, and a through hole connecting the top and the bottom, the top and the bottom are oppositely arranged, and the connecting ball head 142 is fixedly connected with the external structure through a connecting piece assembled in the through hole. The connecting piece is arranged in the through hole, which avoids the structural interference caused by the connection of the connecting piece and the external structure. For example, the above-mentioned connecting piece can be a screw, and the assembly and fixation are realized through the threaded connection of the screw with the through hole and the external structure respectively, which is convenient to operate and has high reliability.

[0073] In some embodiments, the damping member 144 includes an annular structure, which abuts the outer surface 1421 of the connecting ball head 142. With the annular damping member 144, not only can the rotational interference between the connecting ball head 142 and the ball head seat 141 caused by the structure of the damping member 144 be avoided, but also the operation feeling can be improved. For example, the above-mentioned through hole forms a hole position on the outer surface of the connecting ball head 142, and the annular damping member 144 can abut the periphery of the hole position.

[0074] It should be noted that the above-mentioned support 1 can be used to support external devices such as mobile phones and tablets through the support relationship of the device cooperation part 111 to the external devices, so that the external devices have the rotation effect relative to the base 1132a. Alternatively, the above-mentioned support 1 can also be widely used in scenes requiring relative rotation adjustment, such as between a table lamp holder and a lamp rod, between a chair back and a seat headrest, and a rotating mechanism of a toy. The device cooperation part 111 can be assembled with the table lamp holder and the seat headrest, so that the corresponding parts of the lamp holder, the headrest, and the toy obtain the universal rotation effect relative to the base 113.

[0075] In some embodiments, the support 1 further includes a power-consuming component, a connecting circuit component 12, and a power taking plug 13, the power-consuming component is assembled in the device cooperation part 111, the power taking plug 13 is assembled in the base 113, and the connecting circuit component 12 is conductively connected with the power-consuming component and the power taking plug 13 respectively. A power supply system can be formed through the power taking plug 13, the connecting circuit component 12, and the power-consuming component, so that the support 1 contains an electric control function.

[0076] In some embodiments, Figure 4 is a perspective structural schematic diagram of a device support 1 in another exemplary embodiment of the present disclosure, Figure 5 is an exploded structural schematic diagram of a device support 1 in an exemplary embodiment of the present disclosure, Figure 6 is a cross-sectional structural schematic diagram of a device support 1 in an exemplary embodiment of the present disclosure, Figure 7 is a partial exploded structural schematic diagram of a device support 1 in an exemplary embodiment of the present disclosure, and Figures 4-7As shown, the device matching portion 111 includes a first housing 1112 and a mounting substrate 1111 disposed in the first housing 1112. The power-consuming components include a charging coil and a first circuit board 122 electrically connected with the charging coil, so that the device matching portion 111 of the support 1 contains a wireless charging function. The charging coil is assembled on a first side of the mounting substrate 1111 facing the device contact surface of the first housing 1112, and the first circuit board 122 is assembled on a second side opposite to the first side. Assembling the charging coil and the first circuit board 122 on opposite sides of the mounting substrate 1111 not only optimizes the structural layout of the device matching portion 111, but also facilitates the electrical connection convenience of the first circuit board 122 with the connection circuit component 12. Among them, the first circuit board 122 can be used for wireless charging control.

[0077] In other embodiments, the power-consuming components can also include sensors, electric heating components, light components, etc., and one or more power-consuming components can be matched according to the application scenario of the support 1, and the present disclosure does not limit this.

[0078] The material of the above-mentioned mounting substrate 1111 can be metal to improve the overall structural strength of the device matching portion 111. For example, the material of the mounting substrate 1111 is iron.

[0079] The material of the above-mentioned first housing 1112 can be metal, plastic, etc., and the present disclosure does not limit this. The above-mentioned first housing 1112 can enclose a circular structure, a rectangular structure or other shapes, and the present disclosure does not limit this. The first housing 1112 can include a lower shell and an upper shell, the lower shell enclosing a first space accommodating the charging coil and the first circuit board 122, and the upper shell being assembled with the lower opening of the lower shell to enclose the above-mentioned first space.

[0080] Among them, Figure 8 is a partial exploded structural schematic diagram of a device support 1 in an exemplary embodiment of the present disclosure, as Figure 6 , Figure 8 As shown, the wireless charging component can also include a shielding cover 1113 assembled on the second side, the first circuit board 122 being provided with electronic components, and the shielding cover 1113 covering the electronic components to avoid mutual interference of the electronic components with external devices and other electronic components of the support 1.

[0081] In some embodiments, the support 1 can also include a magnetic attraction component 15 assembled on the first side. By magnetically fixing the external device, the device can improve the convenience of taking and placing the device, and improve the user experience. The magnetic attraction component 15 can improve the alignment accuracy of the external device and the device matching portion 111, and improve the charging efficiency of the charging coil on the external device.

[0082] The magnetic attraction assembly 15 can be arranged at the periphery of the charging coil in the circumferential direction of the charging coil to form a positioning assembly for the external device in the circumferential direction, thereby improving the positioning accuracy of the external device and the device cooperation part 111. The magnetic attraction assembly 15 can be a plurality of block-shaped magnets distributed in the circumferential direction of the charging coil to reduce the cost and facilitate assembly.

[0083] In some other embodiments, Figure 9 is a perspective view of a device support 1 according to another exemplary embodiment of the present disclosure, Figure 10 is a partial view of a device support 1 according to an exemplary embodiment of the present disclosure, Figure 11 is a partial view of a device support 1 according to an exemplary embodiment of the present disclosure, showing a support claw 161 in a target position, Figure 12 is a partial view of a device support 1 according to an exemplary embodiment of the present disclosure, showing a support claw 161 in another target position, Figures 9-12 As shown, the support 1 includes a support claw 161 and a key assembly 17, and the device cooperation part 111 is used to provide structural support for the external device, so that the external device is kept in the expected posture. The support claw 161 is movably assembled to the device cooperation part 111 and can be used to support the external device. By adjusting the position of the support claw 161 along the movement direction, the relative position of the external device and the device cooperation part 111 can be adjusted. As shown in Figures 9-12 the dashed arrow can represent the movement direction, which can be the longitudinal direction of the support plane of the device cooperation part 111, or the direction of gravity, or other directions determined according to the support requirements of the support claw 161.

[0084] The support claw 161 is movably assembled to the device cooperation part 111 along the movement direction. The key assembly 17 includes a key body 171 and a reset member 172. The key body 171 is assembled to the device cooperation part 111 and includes a pressing portion protruding from the device cooperation part 111. The reset member 172 is assembled to the device cooperation part 111 and elastically abuts against the key body 171 to switch the key body 171 between a first state and a second state. The key body 171 is provided with a third limiting structure 1711. In the first state, the third limiting structure 1711 is separated from the support claw 161, so that the support claw 161 switches the target position. In the second state, the third limiting structure 1711 is in limiting cooperation with the support claw 161 to limit the support claw 161 in any target position. In the initial state of the key body 171, the support claw 161 can stay in any target position by limiting cooperation between the third limiting structure 1711 and the support claw 161, and can switch between target positions when the key body 171 is in a pressed state and the limiting relationship with the third limiting structure 1711 is broken. Therefore, a simple structure is used to provide a support position matched with the support 1 for different external devices.

[0085] Further, Figure 10 The dotted line can represent a first central axis, and the third limiting structure 1711 is arranged on both sides of the first central axis parallel to the movement direction of the key body 171. The third limiting structure 1711 is arranged on both sides of the first central axis parallel to the movement direction of the key body 171, which improves the movement balance and limiting reliability of the supporting clamping jaw 161.

[0086] In some embodiments, the supporting clamping jaw 161 includes a first clamping jaw body 1611 and a sliding component 1612, the first clamping jaw body 1611 is located outside the device cooperation part 111, and the sliding component 1612 is located inside the device cooperation part 111.
