Electric vehicle wireless charging transmitting and receiving automatic alignment system

Abstract

The invention discloses an electric vehicle wireless charging transmitting and receiving automatic alignment system. The electric vehicle wireless charging transmitting and receiving automatic alignment system comprises a wireless receiving device and a wireless transmitting device, a communication connection being established between the wireless receiving device and the wireless transmitting device. The automatic alignment system further comprises a radio positioning device and a motor positioning driving device; the motor positioning driving device is arranged at the bottom of an electric vehicle; the wireless receiving device is arranged on the motor positioning driving device, and can move leftwards and rightwards under the driving of the motor positioning driving device; a communication connection is established between the radio positioning device and the motor positioning driving device; the radio positioning device includes a radio range-measuring circuit and a radio answering circuit; a communication connection is established between the radio range-measuring circuit and the radio answering circuit; after the radio range-measuring circuit transmits range-measuring radio signals, the radio answering circuit transmits response signals; the radio range-measuring circuit calculates position difference according to time length for receiving the response signals; and therefore, the motor positioning driving device can be controlled to move according to the position difference.

Description

Technical field [0001] The invention involves a wireless charging system for electric vehicles, which specifically involves the launch module in the wireless charging system of the electric vehicle and the system that is automatically accurate by the receiving module.

This patent uses a movable wireless charging transmitting board to realize the alignment and positioning of the transmitting board and the receiving board to improve the transmission efficiency of wireless charging. The disadvantage of this patent is that the movable transmitting board requires a large amount of work on the ground of the parking space Ground-breaking engineering, and it is necessary to excavate enough space for the pre-embedding of the device. If the metal frame structure is used as the support surface, the cost of the entire system will be increased, and the support surface of the metal frame structure also has the possibility of metal absorbing heat from electromagnetic waves.
