Abstract

The embodiment of the invention provides a wireless charging device and system, relates to the technical field of electronic, provides a wireless charging scheme, and aims to solve the problems that wireless charging equipment is heavy in design and a transmitting terminal only can correspond to a single receiving terminal, and improve wireless charging practicability of the equipment. The method comprises the following steps: an integral receiving capacitor is formed by correct para-position of a capacitor polar plate of a wireless charging receiving coil in a wireless charging adapter and the capacitor polar plate of a wireless charging receiving circuit in electronic equipment; the integral receiving capacitor, a first inductance coil and a rectifying circuit form a receiver; the receiver is in magnetic resonant coupling with a wireless charging emission source to receive electrical energy sent by the wireless charging emission source; power is supplied to the loading of to-be-charged equipment after rectifying by the rectifying circuit.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a wireless charging device and system. Background technique [0002] At present, wireless charging technology mostly uses capacitive coupling technology to realize energy transmission, and the energy is transferred to the receiving side through the capacitor formed by the combination of the transmitting end and the receiving end. However, most of this solution needs to integrate the coil in the receiving side circuit into the device to be charged. At the same time, the current tight coupling solution also needs to add a shielding magnetic sheet, which not only increases the thickness of the device, but also increases the weight of the device. Some wireless Charging accessories, such as the wireless charging shell protective cover of the mobile phone, must be added to the protective cover with a power interface to physically connect with the mobile phone to realize cha...
