Document Type and Number:
WIPO Patent Application WO/2022/160939
Kind Code:
A1
Abstract:
The present application discloses a wireless charging device and system. The wireless charging device comprises at least one charging assembly and a controller; each charging assembly comprises a charging transmitting coil and an electromagnetic attraction coil which are matched with each other, wherein each charging transmitting coil and each electromagnetic attraction coil are connected to the controller; and the controller is used for controlling each electromagnetic attraction coil to generate attraction force and controlling each charging transmitting coil to output wireless charging electric energy. Compared with a mode in the prior art that the wireless charging device is marked to allow a user to place a charged device by aligning the charged device to the wireless charging device, the wireless charging device provided by embodiments of the present invention can enable the charged device to be automatically attracted to an accurate charging position, and solves the problem of energy transmission loss caused by position deviation generated because the user does not accurately place the charged device, thereby improving the charging efficiency.
