A wireless charging mobile phone, charging device and its charging method

Abstract

The invention discloses a wireless charged handset and a self-contained wireless charging set of the handset. A loop is arranged in the wireless charging set, and is used as an electromagnetic field emitter. Another loop is arranged near the electromagnetic field emitter in the handset, and is used as an electromagnetic field receiver. Induced current is generated in the receiver through electromagnetic oscillation so that the handset can be charged in a wireless way within certain limits. The steps for wireless charging are as following: A) an electric current oscillator in the wireless charging set can produce changeable current which is transported to a loop A so that the loop A can produce changeable electromagnetic field; B) A loop B is arranged in a charging area of the wireless charging set; and induced current is produced in the loop B; C) the reduced current is transported to a charging battery of the handset to charge the battery. Compared with prior various wireless charging sets, the charging set which charges through exchange of energy of electromagnetic field is manufactured simply; the cost is low; and the capacity usage ratio is high. The charging set can charge various low power electronic products, such as handset and so on, in a wireless way.

Description

【Technical field】 [0001] The invention relates to the field of wireless charging, in particular to a wireless charging mobile phone, a charging device and a charging method thereof. 【Background technique】 [0002] A large number of portable electronic devices such as mobile phones, PDAs, MP3 players, and electric toys all use rechargeable batteries, but in many cases, when the rechargeable batteries of these electronic devices are exhausted, they cannot find a rechargeable power source in time. On the one hand, with the development of science and technology, the development trend of various fashionable electronic products is increasingly rich in functions, resulting in an increasing demand for power supply. On the other hand, for the convenience of portability, manufacturers and consumers are pursuing smaller The size and lighter weight make the design of the power supply a major bottleneck in the development of this type of product. Therefore, designing new charging device...

AI Technical Summary

Problems solved by technology

General wireless charging equipment is relatively large in size, and can only power some low-function electronic devices for demonstration purposes, such as light-emitting diodes, small fans, etc., and the energy conversion rate of the power supply process is very low, mainly through the change of the electromagnetic field to transmit energy. And complete the conversion of energy, in the conversion process, most of the energy is lost
