Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. In order to facilitate the understanding of the wireless charger provided by the embodiment of the present application, its application scenario is firstly introduced below.

[0038] With the great development and popularization of consumer electronic products, portable electronic products bring great convenience to people's life. However, different products need to be configured with different charging adapters. Due to factors such as the interfaces of different products cannot be shared, and the power of different products is not compatible, the versatility of the adapters among various manufacturers is poor. In addition, factors such as many wires in the wire charging method and the need to plug and unplug cables for charging greatly reduce the convenience of users.

Abstract

The invention provides a wireless charger and a wireless charging system for wearable equipment, and relates to the field of wireless charging. The wireless charger comprises a charging base, a connector and a cable, the charging base and the connector are connected through the cable, and the charging base comprises a first shell and a transmitting coil arranged in the first shell. The wireless charger further comprises a booster circuit and an inverter circuit, the booster circuit is arranged outside the first shell, and the booster circuit is used for boosting a direct-current voltage signal input through the connector; the inverter circuit is arranged between the booster circuit and the transmitting coil, and is used for converting the direct-current voltage signal obtained after boosting into an alternating-current voltage signal and transmitting the alternating-current voltage signal to the transmitting coil; the transmitting coil is used for converting the electric energy of the AC voltage signal into electromagnetic energy for wireless transmission. By adopting the wireless charger provided by the invention, the heat consumption of the charging base can be reduced on the basis of effectively improving the charging efficiency, so that the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of wireless charging, in particular to a wireless charger and a wireless charging system for wearable devices. Background technique [0002] In the wireless charging technology, the electronic device and the wireless charger do not need to be connected by a power cord, and the electronic device can be charged only by placing the electronic device on the wireless charger, which is convenient for users. Moreover, the contact terminal for connecting the power line can also be omitted on the electronic device, thereby improving the safety, waterproof and dustproof performance of the electronic device. Therefore, in recent years, the application of wireless charging technology to charge electronic devices has become highly respected. [0003] With the gradual popularization of wireless charging on low-power electronic devices (wearable devices such as smart bracelets, watches or rings), users have also...
