[0002] The current wireless charging process adopts the charging method of a single transmitting coil to a single receiving coil, that is, during the charging process, the position of the transmitting coil in the power transmitting module of the wireless charging device is fixed, and is carried out by the receiving coil and the transmitting coil of the device to be charged. Coupling charging requires that the position between the charged device and the wireless charging device be strictly aligned to ensure the tight coupling between the transmitting coil and the receiving coil. Once the relative position between the charged device and the wireless charging device deviates, it will cause charging Efficiency drops, that is, prolonging the charging time, and objectively causing waste of electric energy

Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] see figure 1 , figure 1 It is a block diagram of the wireless charging system of the present invention. In this embodiment, the wireless charging system includes a transmitting device 11 and a device to be charged 12 , the transmitting device 11 includes a first current applying device 111 and a transmitting coil 112 , and the device to be charged 12 includes a second current applying device 121 and a receiving coil 122 .
[0022] The first current loading device 111 is used to load the first current in the transmitting coil 112, and the second current loading device 121 is used to load the second current in the receiving coil 122 so that the transmitting coil 112 and the receiving coil 122 act on the Lorentz force. The lower relative position changes, thereby aligning the receive coil 122 and the transmit coil 112 .
