The supporting assembly 20 is used to support the fixing assembly 10. The steering joint 30 is connected between the fixing assembly 10 and the supporting assembly 20 so that the fixing assembly 10 can rotate relative to the supporting assembly 20 to adjust the use and/or operating angle or direction of the mobile terminal.

The conductive circuit 40 extends from the inside of the support assembly 20 through the inside of the steering joint 30 to the inside of the fixing assembly 10, and then is connected to the wireless charging module 12. That is, the conductive circuit 40 is arranged inside the wireless charging stand 1 for a vehicle, and supplies power to the wireless charging module 12.

Please refer to FIG. 3. In one embodiment, the steering joint 30 includes a spherical shaft 32 and a sleeve 34. The sleeve 34 is sleeved on the spherical shaft 32 and can rotate relative to the spherical shaft 32. The spherical shaft 32 includes a spherical body 321 and a shaft 322. One end of the shaft 322 is connected to the spherical body 321, and the other end is connected and fixed to the support assembly 20. That is, the spherical shaft 32 is connected and fixed to the supporting assembly 20 through the shaft 322.

The spherical shaft 32 has a through hole 323. The through hole 323 penetrates the spherical body 321 and the shaft 322 along the axial direction of the spherical shaft 32 and communicates with the internal space of the support assembly 20. That is, the through hole 323 is along the direction of the shaft 322 and penetrates the shaft 322 and the spherical body 321. One real In the embodiment, the shaft 322 has a tubular structure, the spherical body 321 has a penetrating opening, and the nozzle of the shaft 322 is just connected to the opening of the spherical body 321, and together constitutes the through hole 323. .

In one embodiment, the spherical body 321 and the shaft 322 are manufactured in an integral manner, and then connected and fixed to the support assembly 20. In addition, the spherical body 321, the shaft 322 and the support assembly 20 can also be manufactured in an integrated manner. That is, when making the housing of the support assembly 20, a spherical shaft 32 protruding from one side of the support assembly 20 and communicating with the inner space of the support assembly 20 is also made at the same time.

In an embodiment, as shown in the figure, the conductive circuit 40 may be a wire, which extends from the inner space of the support assembly 20 through the through hole 323 to the inner space of the fixing assembly 10, and is connected to the fixing assembly 10. The wireless charging module 12 is provided inside to provide power to the charging tray 122.

In one embodiment, the sleeve 34 includes a compression knob 341 and a socket seat 342. The compression knob 341 is provided with an internal thread, and the socket seat 342 is provided with an external thread to follow the compression knob. 341 is screwed and fixed. As shown in FIGS. 3 and 4, the compression knob 341 has a sleeve ring structure, and an internal thread is provided on the inner side of the sleeve ring structure. The socket 342 includes a cylindrical wall extending toward the pressing knob 341, and an external thread is provided on the outer surface of the cylindrical wall. Inside the socket seat 342, that is, at the bottom of the cylindrical wall, there is an arc-shaped cavity 3421 for accommodating the spherical body 321, and an opening 3422 at the bottom of the arc-shaped cavity to communicate with the fixed The internal space of the component 10. As shown in Fig. 4, the cylindrical wall is composed of at least four wall surfaces with threaded sections, and the wall surfaces of the threaded sections are made of elastic materials.

When the spherical shaft 32 and the sleeve 34 are sleeved together, the spherical body 321 at the front end of the shaft 322 will pass through the sleeve structure of the compression knob 341 and the cylindrical wall of the sleeve seat 342 in sequence, and reach And it is accommodated in the arc cavity of the socket 342. After the compression knob 341 is locked to the socket seat 342 After being mounted, the spherical body 321 can be prevented from escaping from the arc-shaped cavity 3421, and the sleeve 34 can be rotated relative to the spherical shaft 32.

In addition, there is a protrusion 3423 on the inner surface of the arc-shaped cavity 3421, which cooperates with the limiting member 3213 to limit the rotation range of the sleeve 34 relative to the spherical body 321. That is, when the sleeve 34 continues to rotate in one direction, if the protrusion 3423 on the inner surface of the arc described cavity 3421 abuts against the stopper 3213 on the spherical body 321, the sleeve 34 can no longer move along. If you continue to rotate in this direction, you can only rotate the sleeve 34 in the opposite direction or change other directions. Such a configuration can prevent the conductive circuit 40 from being excessively twisted to cause damage when the angle of rotation of the sleeve 34 is too large, thereby affecting the power supply performance of the charging circuit and the charging effect on the mobile terminal.

It should be particularly noted that the sleeve 34 can drive the fixed assembly 10 to rotate in different angles and directions during the rotation, so that the mobile terminal fixed on the fixed assembly 10 can be rotated to the angle or direction required by the operator. However, since a conductive circuit 40 is also provided between the sleeve 34 and the spherical body 321 to provide power to the wireless charging module 12, in order to avoid excessive rotation of the sleeve 34 in the same direction, the conductive circuit 40 is excessively twisted. As a result of disconnection or loosening, the rotation range of the sleeve 34 can be restricted by the above-mentioned protrusion 3423 and the limiting member 3213.

Please refer to FIG. 6, in an embodiment, the fixing assembly 10 includes a A front housing 13 and a rear housing 15 are assembled, and the assembled internal space is used to accommodate the above-mentioned circuit board 121 and the charging tray 122.

As shown in the figure, the clamping portion 16 includes an upright plate structure and clamping members 161 extending laterally at the upper and lower ends of the plate structure. The part of the plate structure is fixed in the internal space after the front housing 13 and the rear housing 15 are assembled, and the two clamping pieces 161 protrude from the upper and lower sides of the front housing 13 and the rear housing 15 to facilitate Clamping mobile terminal. In one embodiment, the clamping member 161 is a small roller with concave-convex patterns and has certain elasticity.

When the fixing assembly 10 is assembled, the clamping portion 16, the circuit board 121 and the charging disk 122 are locked between the front housing 13 and the rear housing 15. In addition, the fixing assembly 10 may further include a plastic shell and a bearing pad 14, which may be sequentially arranged on the outer surface of the front shell 13. Wherein, the bearing pad 14 is provided on the outermost layer of the fixing assembly 10 for bearing the mobile terminal. The bearing pad 14 can be a soft pad with anti-slip function, a wood grain sticker, or a plastic board.
