A long-distance wireless charging device

Abstract

The present invention relates to a long-distance wireless charging device. The long-distance wireless charging device is a non-contact inductive charging device. The long-distance wireless charging device includes an energy transmitting module, an energy transfer module and an energy receiving module , the input end of the energy transmission module is coupled to an external power frequency AC power supply, and is used to convert the input electric energy into magnetic field energy for emission; the energy transfer module is provided with at least one, and the energy transfer module The input end is coupled to the output end of the energy transmitting module, and the energy transfer module is used to transfer the magnetic field energy emitted by the energy transmitting module to extend the wireless charging distance; the input end of the energy receiving module is coupled to the output of the energy transfer module At the end, the energy receiving module is used to receive the magnetic field energy transferred by the energy transfer module, and convert it into electric energy to charge the battery of the electric device. Solve the problem of short transmission distance and inconvenient use of the current wireless charger.

Description

technical field [0001] The invention relates to the technical field of wireless transmission, in particular to a long-distance wireless charging device, which is mainly designed for extending the energy wireless transmission distance, so that portable electronic devices such as mobile phones, Pads and notebook computers can be charged more conveniently. Background technique [0002] At present, what portable electronic equipments such as mobile phone, MP3 and notebook computer carry out charging mainly adopt is the traditional charging method that one end is connected with AC power supply, and the other end is connected with portable electronic equipment rechargeable battery. This charging method has many disadvantages. First of all, frequent plugging and unplugging is easy to damage the connector, and it may also bring the risk of electric shock, and it is extremely inconvenient to use the plugging and unplugging data cable. , There is no way to charge at all, which affects...
