Charging device

Abstract

The invention discloses a charging device, which comprises an alternating current module, a wireless transmitting module, a wireless receiving module and a charging module, wherein the alternating current module is used for providing first alternating current for the wireless transmitting module; the wireless transmitting module is used for receiving the first alternating current provided by the alternating current module, converting the first alternating current into electromagnetic wave and transmitting the electromagnetic wave to the wireless receiving module; the wireless receiving module is used for receiving the electromagnetic wave transmitted by the wireless transmitting module and converting the electromagnetic wave into second alternating current as well as transmitting the second alternating current into direct current and providing the direct current to the charging module; the charging module is used for receiving the direct current provided by the wireless receiving module and charging equipment connected with the charging device by using the direct current; the wireless transmitting module is respectively connected with the alternating current module and the wireless receiving module; and the charging module is connected with the wireless receiving module. According to the charging device disclosed by the invention, wireless charging can be realized without wiring and high energy transmission efficiency is obtained.

Description

technical field [0001] The present invention relates to a charging device, in particular to a wireless charging device for a mobile terminal. Background technique [0002] The charging of various portable electronic devices such as cell phones, personal electronic assistants, MP3s, etc. is a headache. The current charging method mainly adopts the traditional charging method in which one end is connected to the AC power supply and the other end is connected to the rechargeable battery of the portable electronic device. This method has many disadvantages. In addition to the need to use different chargers for different electronic products, When charging, it is necessary to find a suitable socket and straighten out the wiring of the charger. Frequent plugging and unplugging can easily damage the connector. In addition, it may bring the danger of electric shock, which is time-consuming and laborious to operate. Therefore, if a non-contact inductive charger can be found, the abov...
