Problems solved by technology

[0003] When the battery power is insufficient, it needs to be charged in time. At present, the mainstream charging method is to use wired charging piles and chargers to charge electric vehicles. The wired charging method is not only troublesome to operate, but some charging devices are heavy and laborious, and often have Larger safety hazards, prone to electric leakage, electric shock accidents, maintenance troubles, and high failure rates. At present, wireless charging technology has gradually matured. Using wireless charging to charge electric vehicles is not only convenient and fast, but also improves safety. Maintenance, less failure rate
One of the current problems is that the distance between the power transmitting end and the receiving end of the existing electric vehicle wireless charger is not adjustable, the distance between the two is not shortened as much as possible, the energy loss is large, the energy transmission efficiency is low, and the charging speed is slow

Embodiment 1

[0017] When in use, the electric vehicle is parked in the parking space at will, and the position detection device installed on the track sends out a detection signal to determine the position of the position feedback device on the wireless charger, and moves the base and the mechanical arm according to the detected position signal To the vicinity of the wireless charger, the mechanical arm will send the wireless charging board to the bottom of the wireless charger, so that the wireless charging board and the wireless charger fit closely, and then start charging.

Embodiment 2

[0019] There are 2 mechanical arms installed on the track; when in use, park 2 electric vehicles in the parking space at will, and the position detection device installed on the track sends a detection signal to determine the position of the position feedback device on each wireless charger. According to the detected position signal, the base and the robotic arm are moved to the vicinity of each wireless charger, and the robotic arm sends the wireless charging board to the bottom of the wireless charger, so that the wireless charging board and the wireless charger are closely attached, and then start Charge.

Abstract

A wireless charging system for electric vehicles is characterized by comprising a vehicle-mounted portion and a charging pile portion; the charging pile portion comprises a control system, a track fixed to a parking space, a position detector mounted on the track, a base mounted on the track, a manipulator mounted on the base, and a wireless charging panel mounted at the top of the manipulator; the vehicle-mounted portion comprises a wireless charger and a position feedback device, the wireless charger is fixed to a chassis of an electric vehicle, and the position feedback device is fixed to the wireless charger. The wireless charging system has the advantages that through active judgment on the position of a wireless charging receiving terminal, the manipulator moves the wireless chargingpanel to a position nearest to the wireless charger by movement on the track and its degree of freedom, so that requirements on the parking position accuracy of the electric vehicle can be reduced, energy loss can be also decreased, energy transmission efficiency can be improved, charging speed can be increased, large-area wireless chargers do not need to be added to the bottom of the electric vehicle, and the integrity of the bottom structure of the electric vehicle is not damaged.

Description

technical field [0001] The invention belongs to the field of wireless charging, and in particular relates to a wireless charging system for electric vehicles. Background technique [0002] Electric vehicles refer to vehicles powered by vehicle-mounted power supplies, driven by motors to drive wheels, and meeting the requirements of road traffic and safety regulations. Electric vehicles use batteries to provide kinetic energy. Compared with traditional internal combustion engine vehicles, electric vehicles have the advantages of energy saving, low noise, strong power, simple structure, and low maintenance costs. Environmental protection and air cleanliness are very beneficial, and the direct pollution is almost zero. [0003] When the battery power is insufficient, it needs to be charged in time. At present, the mainstream charging method is to use wired charging piles and chargers to charge electric vehicles. The wired charging method is not only troublesome to operate, but...
