Description

Technical Field

[0001] The utility model relates to an electric connecting device and an electric vehicle. Background Art

[0002] Electric vehicles generally use replaceable battery packs, which can be removed at any time for replacement or charging. After replacement or charging, they are installed on the vehicle body. In existing electric vehicles with replaceable structures, 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 body 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.

[0003] At present, the installation position of the vehicle-end electrical connector is relatively fixed. The vehicle-end electrical connector is generally installed at the front end of the electric vehicle. For electric vehicles that adopt 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 adopt rear-wheel drive, the cable is plugged into the socket of the vehicle-end electrical connector at the front end of the electric vehicle through an adapter plug. However, the existing adapter plug is located above the vehicle-end electrical connector. In addition to the connection, there is no additional support or fixing structure for the two. After long-term use, the plug is easily deformed or falls off. Utility Model Content
