Abstract

Disclosed in the invention is a wireless charging transmitting circuit comprising a transmitting circuit control center, a drive circuit, an energy emitting circuit, a wireless transmitting coil, a current detection circuit, a motor control, and a motor. The current detection circuit is used for colleting the working current of the energy emitting circuit and feedbacking the collected working current to the transmitting circuit control center; the transmitting circuit control center is used for adjusting the axis position of the wireless transmitting coil; and the motor controller controls drives the motor to adjust the position of the wireless transmitting coil according to the position control signal provided by the transmitting circuit control center, so that the axis of the wireless transmitting coil and the axis of a wireless receiving coil trend to be consistent. According to the invention, convenience can be brought for application of wireless charging equipment, the potential safety hazard caused by wireless charging application during driving process can be reduced, and thus security of vehicle-mounted wireless charging application is improved.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging transmitting circuit. Background technique [0002] Wireless charging technology is a technology for charging by using corresponding coils at the sending and receiving ends to send and receive induced AC signals. The car mobile phone wireless charger is divided into two parts: transmitting and receiving. The transmitting part is connected to the vehicle power supply and used for energy transmission. The receiving part is installed in the mobile phone waiting for charging equipment. The receiving part receives the energy from the transmitting part and charges the equipment to be charged. Usually, after the device to be charged is placed at a designated location, the transmitting part communicates with the receiving part, and charging starts after the communication is successful. When the center of the wireless transmitting coil in the transmitting pa...
