For example, the first driving member includes a motor and a screw rod connected to a power output end of the motor, and the first slider 32 is threadedly connected to the screw rod. The first driving member can be used to drive the first slider 32 to move left and right.

In some embodiments of the present application, the second adjustment mechanism further includes a second slider 42 and a second guide rail 43. The first guide rail 33 is fixedly connected with the second slider 42, the second guide rail 43 is disposed on the support panel 22 along the second direction, and the second slider 42 is slidably disposed on the second guide rail 43.

The fixed end of the second driving member is fixedly connected with the second guide rail 43, and the driving end of the second driving member is fixedly connected with the first slider 32. The first driving member drives the first sliding block 32 to slide on the second guide rail 43, so as to drive the whole first adjusting mechanism and the wireless charging module 1 to move along the second direction.

Further, in some embodiments of the present application, the second driving element includes a second pulley 411, a second driving rope 412 and a second knob 413. The second wire wheel 411 is rotatably disposed at one end of the second guide rail 43 in the second direction, one end of the second driving rope 412 is fixedly connected to the second slider 42, and the other end of the second driving rope 412 is wound around the second wire wheel 411. The second knob 413 is coaxially and fixedly connected with the second wire wheel 411.

Specifically, the rotation axis of the second wire wheel 411 is perpendicular to the plane of the support panel 22. An annular groove is formed on the peripheral side of the second pulley 411, and the second driving rope 412 is wound in the annular groove. The second knob 413 is rotated to drive the second pulley 411 to rotate so as to shorten the second driving rope 412, and therefore the second sliding block 42 is driven to move towards the direction close to the second pulley 411.

Further, the second pulley 411 is disposed in a frame, and a stopper for restricting rotation of the second pulley 411 is disposed at a position on the frame corresponding to the second pulley 411. When the position adjustment of the wireless charging module 1 in the second direction is completed, the rotation of the second reel 411 is restricted by the stopper.

Optionally, the second slider 42, the second guide rail 43 and the second driving rope 412 are disposed inside the frame, and the second knob 413 is disposed outside the frame. The structure of the stopper is the same as that of the stopper for restricting the first pulley 311, and the connection relationship between the stopper and the second pulley 411 is the same as that between the stopper and the first pulley 311, and thus the description thereof is omitted.

In some embodiments of the present invention, in the using state of the wireless charging device, one end of the supporting panel 22 in the second direction is located above the other end, and the second driving element is disposed at one end of the supporting panel 22 close to the upper end in the second direction.

For example, as shown in fig. 1, one end of the support panel 22 is rotatably connected to the base 21 by a rotation shaft 231. In the use state, one end of the supporting panel 22 away from the rotating shaft 231 is located above the rotating shaft 231, and the second wire wheel 411 is disposed at one end of the supporting panel 22 away from the rotating shaft 231. When the wireless charging module 1 needs to be moved to a direction close to the rotating shaft 231, the limit of the stopper on the second wire wheel 411 can be released, the first adjusting mechanism slides to the lower end in the direction of the rotating shaft 231 under the action of self gravity, and then the position of the wireless charging module 1 in the second direction is adjusted by rotating the second knob 413.

Further, the second adjusting mechanism includes another elastic restoring member, one end of the elastic restoring member is fixedly connected to the second slider 42, and the other end of the elastic restoring member is fixedly connected to one end of the second guide rail 43 away from the second pulley 411. The elastic return member is also in a stretched state, and may be a return spring or an elastic cord, etc. The second slider 42 can move away from the second pulley 411 under the elastic restoring force of the elastic restoring member. When the wireless charging module 1 needs to be adjusted in a direction away from the second reel 411, the limit of the stopper on the second reel 411 can be firstly released, the second slider 42 returns to one end of the second guide rail 43 away from the second reel 411 under the action of the elastic reset piece, and then the second knob 413 is rotated, so that the wireless charging module 1 reaches a specified position.

Alternatively, the connecting member 232 is a strip-shaped plate structure, and one end thereof is fixedly connected to the rotating shaft 231 by a screw.

Wherein, the center of the arc is located on the center line of the rotating shaft 231. When the other end of the connecting member 232 is located at a different positioning hole 211, the angle between the supporting panel 22 and the base 21 is different. When the angle between the supporting panel 22 and the base 21 needs to be adjusted, the locking member 233 is released, and the other end of the connecting member 232 is rotated around the center line of the rotating shaft 231, so as to drive the supporting panel 22 to rotate around the center line of the rotating shaft 231. Then, the locking member 233 is penetrated through the through hole and the positioning hole 211 corresponding to the desired angle. Finally, the locking member 233 is locked to the base 21, so that the connecting member 232 is clamped between the locking member 233 and the base 21 to prevent the support panel 22 from rotating relative to the base 21.

Alternatively, the locking member 233 may be a locking knob. The locking knob is in threaded connection with the positioning hole 211.
