A positioning mechanism is arranged between the lower end of the end cap body and the upper end of the battery box shell, limiting seats are arranged on the inner walls of two sides of the upper end of the battery box shell, two mounting plates are arranged at the bottom of the end cap body, an electric cylinder is connected on each mounting plate and connected with a limiting plate, each limiting plate extends to space below the corresponding limiting seat under action of the corresponding electric cylinder, a wiring hole is formed in the top of the end cap body, and the upper end of the wiring hole is connected with a wiring column. The new energy vehicle battery box has the advantages of being simple in structure, easy to manufacture, practical and efficient.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an end cover of a battery box of a new energy vehicle. Background technique [0002] Power batteries are widely used as batteries for electric vehicles, electric bicycles, electric trains, and golf carts because of their small size, light weight, strong power, no memory, and environmental protection. [0003] In order to use the power battery safely, the power battery is equipped with an explosion-proof hole. The liquid injection hole and the explosion-proof hole of the existing power battery are set separately, and the process is complicated; Press the steel ball, but the steel ball will affect its sealing with the vibration of the battery, and the performance is unstable. Contents of the invention [0004] The invention plays a role of self-protection by providing an exhaust hole and an exhaust valve on the main body of the end cover to prevent excessive pressure...
