Description

Technical Field

[0001] The utility model relates to an electric connector device and an electric vehicle comprising the same. Background Art

[0002] At present, automobile exhaust emissions are still an important factor in environmental pollution. In order to control automobile exhaust, people have developed natural gas vehicles, hydrogen fuel vehicles, solar vehicles and electric vehicles to replace fuel vehicles. Among them, electric vehicles have the most promising application prospects. At present, electric vehicles mainly include direct charging and quick-change types. Due to the restrictions on charging time and location, many new energy electric vehicles are gradually adopting the mode of quick battery replacement for energy replenishment.

[0003] When replacing batteries in electric vehicles, the battery swapping equipment removes the depleted batteries from the electric vehicle and transfers them to the battery transfer equipment, which then transfers the depleted batteries to the battery compartment for charging. Afterwards, the battery transfer equipment takes out the fully charged batteries from the battery compartment and transfers them to the battery swapping equipment, which then installs the fully charged batteries into the electric vehicle.

[0004] In existing electric vehicles, the cable on the electric vehicle is plugged into the socket of the vehicle-end electrical connector through a plug, and a corresponding installation position is set on the quick-change bracket of the vehicle body. After the battery pack is placed in the installation position, it is connected to the vehicle-end electrical connector on the vehicle body through the battery-end electrical connector, and then fixed with a locking device. In this process, the electrodes of the battery-end electrical connector on the battery pack need to contact the electrodes on the vehicle-end electrical connector to ensure power output.

[0005] At present, the installation position of the vehicle-end electrical connector is relatively fixed. The vehicle-end electrical connector is generally installed on the front beam of the quick-change bracket. For electric vehicles that use front-wheel drive, the cable can be directly inserted into the socket of the vehicle-end electrical connector through a plug. For electric vehicles that use rear-wheel drive, the cable needs to be bent 180 degrees before the plug is plugged into the socket of the vehicle-end electrical connector on the front beam. Due to the large turning range of the cable and the detachable plug-in connection between the plug and the socket, the electrical connection between the plug and the socket is prone to loosening, and even abnormalities such as electrical connection failure or burning, which can easily affect the stability, reliability and service life of the electrical connection.
