The first rail 141 and the second rail 142 are positioned and have a length corresponding to the wireless charging area on the support platform 3 such that the charging dock 13 can move within a range that substantially covers the wireless charging area.
In an example, the first rail 141 may be fixedly disposed on the support plate 2 of the table body 21, and the first rail 141 may be provided with a slide bar corresponding to the second rail 142, so that the first rail 141 can slide along the second rail 142. The first driving motor 1431 is configured to drive the first guide rail 141 to slide.

Referring to fig. 11, fig. 11 is a block diagram of a circuit structure of a wireless charging system according to another embodiment. Alternatively, one controller 15 of the plurality of wireless charging boxes 1 serves as the main controller 2, the main controller 2 is in communication connection with the controllers 15 of the remaining wireless charging boxes 1, and the controllers 15 of the remaining wireless charging boxes 1 are controlled by the main controller 2.
There are at least two embodiments regarding the operational cooperation of the respective wireless charging boxes 1. In one embodiment, the plurality of wireless charging boxes 1 operate in a serial manner to reduce interference with each other when the detection board 12 detects the position of the device to be charged 4. Specifically, the main controller 2 is configured to control the detection boards 12 of the plurality of wireless charging boxes 1 to sequentially perform detection of the position of the device to be charged 4.
When the detection board 12 of a certain wireless charging box 1 detects that the device 4 to be charged is in the corresponding area, the main controller 2 or the controller 15 in the wireless charging box 1 can immediately control the shifting mechanism 14 to move so as to shift the charging base 13 to the corresponding position, and start charging the device 4 to be charged. Alternatively, when the detection board 12 of a certain wireless charging box 1 detects that the area corresponding to the wireless charging box 1 has the device 4 to be charged, the main controller 2 or the controller 15 in the wireless charging box 1 does not immediately control the shifting mechanism 14 to move, but when the detection boards 12 in all the wireless charging boxes 1 complete the detection, the main controller 2 coordinates the shifting mechanisms 14 in the wireless charging boxes 1 to simultaneously work, so that the charging bases 13 in the wireless charging boxes 1 simultaneously charge the device 4 to be charged.
In another embodiment, the plurality of wireless charging boxes 1 operate in a parallel manner, that is, the main controller 2 is used for controlling the detection boards 12 of the plurality of wireless charging boxes 1 to simultaneously detect the positions of the devices to be charged 4 in the areas corresponding to the wireless charging boxes. Then, the main controller 2 coordinates and detects the displacement structure in the wireless charging box 1 of the device to be charged 4 to displace to a corresponding position according to the detection result of the detection board 12 in each wireless charging box 1, so that the charging base 13 in each wireless charging box 1 supplies power to the device to be charged 4 together. The wireless charging box 1 operates in a parallel manner, and the efficiency of detecting the position to be charged can be greatly improved.
