[0002] In modern life, smart terminals have become necessities in daily life and often need to be charged when the battery is low, such as smart watches, matching wireless Bluetooth headsets, mobile phones, tablets, laptops, etc.

[0003] As smart terminals have increasingly higher requirements for power convenience, immediacy, special occasions, and special geographical environments, contact-based power transmission is increasingly unable to meet actual needs. In addition, existing smart terminals are generally equipped with wireless charging modules, and users also need to be equipped with wireless chargers.

[0004] Wireless charging is a device that uses the principle of electromagnetic induction to charge. Its principle is to place a coil at the sending and receiving ends. The sending coil sends an electromagnetic signal to the outside world under the action of electricity, and the receiving coil receives the electromagnetic signal and converts it into current, thereby achieving the purpose of wireless charging.
