Charging connector for electric vehicle

Abstract

The invention discloses a charging connector for an electric vehicle, and belongs to the technical field of charging connectors. The charging connector comprises a vehicle battery and a charging box, and further comprises a connecting plate, a charging connecting mechanism, an auxiliary mechanism, a wiping mechanism, a jacking mechanism and a clamping mechanism; the connecting plate is slidably mounted on the charging box, the charging connecting mechanism is mounted on the connecting plate, the clamping mechanism is installed on the side wall of the charging connecting mechanism, the wiping mechanism is installed in the charging connecting mechanism, the jacking mechanism is installed in the charging box and located below a connecting plate, the auxiliary mechanism is installed in the charging box, and a temperature detector which is electrically connected with the vehicle battery and the jacking mechanism is arranged on the vehicle battery. According to the charging connector for the electric vehicle, a plug is clamped to prevent loosening during charging, and when the vehicle battery is overheated and the charging time is enough, the vehicle battery is popped out, and the charging socket is wiped at the same time.

Description

technical field [0001] The invention relates to the technical field of charging connectors, in particular to a charging connector for electric vehicles. Background technique [0002] Battery electric vehicles, plug-in hybrid electric vehicles and fuel cell vehicles typically include high voltage batteries. In operation, the battery provides power to run various components in the vehicle (for example, the electric motor used to drive the vehicle's drive wheels), and when the battery loses charge or discharges, which occurs primarily due to the operation of the vehicle, the battery The state of charge (SOC) decreases. As the battery discharges, it may be desirable or necessary to recharge the battery. Therefore, a power source outside the vehicle is often used to charge the battery through the vehicle charging connector to increase the battery capacity. [0003] The existing Chinese invention patent with publication number CN102403619A discloses a charging connector for ele...

AI Technical Summary

Problems solved by technology

[0004] When the above patents are in use, there are many deficiencies. First, the contact between the electrical plug on the charging connector and the outside world will cause the contact surface to oxidize and produce a metal oxide layer, which will cause the plug to heat up during charging, and the heating time is too long It will lead to a short circuit or poor contact of the connector, and damage the charging connector and battery; second, the above-mentioned patent cannot handle the plug and charging connector according to the charging time and battery temperature, and the charging time greatly affects the battery life and battery temperature. Performance, overcharging will reduce its service life, overcharging will make the vehicle battery heat, serious cases may cause spontaneous combustion, explosion and other dangers
