Abstract
The invention discloses a wireless charging device. The wireless charging device comprises a power supply, a power amplifier, a switch button, a state indicator lamp, a charging module, a sensor module and a control module. Daily alternating current is converted into direct current through voltage reduction, rectification and filtering by the power supply. The direct current supplied by the power supply is converted into needed frequency alternating current through the power amplifier and the needed frequency alternating current is sent to a coil of the charging module. A main power switch of the charging device with the indicator lamp is controlled through the switch button. The state indicator lamp is used for indicating the charging state of charging equipment in the normal charging process. The sensor module is arranged in the charging module and used for detecting the position of equipment to be charged. The control module receives signals of the sensor module and is used for controlling the charging module to send out charging information. The electromagnetic induction power supply mode and the wireless power supply mode are adopted for charging the portable equipment, the problem that the model of a charger is not matched with the model of the equipment is solved, and meanwhile the position placement problem of the charger and the charging equipment in a traditional wireless charging mode is solved.
