Embodiment Construction

[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings required in the embodiments of the present invention. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For Those of ordinary skill in the art can also obtain other drawings based on these drawings without any creative effort.

[0023] First of all, in the existing wireless charging receiver, such as figure 1 As shown, under the same output power of the receiving coil, the larger the output voltage, the smaller the output current, and the smaller the output current, the smaller the thermal power generated by the receiving coil, etc., so by increasing the output voltage of the receiving coil , to reduce the thermal power of the receiving coil, thereby reducing energy loss and increasing the charging speed. For example, if the output power...

Abstract

The invention provides a wireless charging receiving terminal, a wireless charging method and a mobile terminal. The wireless charging receiving terminal comprises an MCU (micro control unit) connected with a battery module in the mobile terminal and used for information interaction with a wireless charging transmitting terminal in the wireless charging process, so that energy transmitted by the wireless charging transmitting terminal is demodulated to the wireless charging receiving terminal, and the battery module is used for power supply in the wireless charging process. According to the scheme, the battery module is used for supplying power to the MCU in the wireless charging receiving terminal, so that the charging speed during wireless charging can be increased by increasing output voltage of the wireless charging receiving terminal as compared with existing wireless charging processes, and rapid charging is realized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless charging receiving end, a wireless charging method and a mobile terminal. Background technique [0002] With the development of wireless communication technology, wireless charging technology has gradually become the mainstream, and people's demand for wireless charging is increasing. With the help of the wireless charging process, the mobile terminal can be easily and conveniently charged. Compared with the wired charging method, the connection of the charging wire can be omitted. [0003] At present, the wireless charging receiver mainly includes a receiving coil 01, a synchronous rectifier 02, a low dropout regulator (Low Dropout Regulator, LDO) 03 and a micro control unit (Micro Control Unit, MCU) 04, such as figure 1 shown. Wherein, the receiving coil 01 is used to generate induced electromotive force in the alternating magnetic field gene...
