Electrical vehicle wireless charging transmitting and receiving automatic alignment system

Abstract

The present invention discloses an electrical vehicle wireless charging transmitting and receiving automatic alignment system which comprises a wireless receiving device and a wireless transmitting device. The communication connection is established by the wireless receiving device and the wireless transmitting device in a certain distance. The automatic alignment system also comprises an image recognition automatic positioning device and a motor positioning driving device arranged at the bottom of an electric vehicle. The wireless receiving device is arranged on the motor positioning driving device and is driven by the motor positioning driving device to move back and forward and left and right. Wired or wireless communication connection is established by the image recognition automatic positioning device and a motor positioning driving device. The image recognition automatic positioning device comprises a collection unit which collects a wireless transmitting device position image, an analysis unit which analyzes the wireless transmitting device position image collected by the collection unit, a control unit which controls the analysis result of the analysis unit and drives the motor positioning driving device to move.

Description

technical field [0001] The invention relates to a wireless charging system for an electric vehicle, in particular to a system for automatically aligning a transmitting module and a receiving module in the wireless charging system for an electric vehicle. Background technique [0002] Because of its advantages of fuel saving, environmental protection and high efficiency, electric vehicles are generally regarded as an important clean transportation tool in the 21st century by scientists and industries all over the world. Among them, electric vehicle charging stations and charging networks are important infrastructure for the large-scale and industrialized development of electric vehicles. [0003] In existing electric vehicle charging stations, when charging electric vehicles using wireless charging, it is necessary to align the wireless receiving board arranged at the bottom of the vehicle with the wireless transmitting board arranged on the ground to ensure the maximum charg...

Problems solved by technology

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.
