Abstract

A battery box protecting box of an electric vehicle comprises a battery box body, fixing pins, a control cylinder and a gas storage device. The battery box body is fixedly connected with a vehicle body through the fixing pins installed on the periphery of the box body, the control cylinder controls the fixing pins to be inserted forwards and pulled backwards through a piston rod, the gas storage device is communicated with a rod cavity of the control cylinder through a gas storage pipeline, and a pressure generator capable of generating a lot of gas quickly is arranged in the gas storage device. The pins are combined with the vehicle body of the electric vehicle, and control and fixation are conducted by means of the control cylinder, so a battery pack can be quickly replaced; the gas storage device is matched with the pressure generator, so when the electric vehicle collides with another vehicle, the pressure generator can be detonated by a collision sensor, the piston rod is pushed back through generated excessive pressure, the battery box body quickly falls off, all combustion sources of the electric vehicle are isolated in time, and use safety of the electric vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of battery box safety, and in particular relates to a battery box protection device for an electric vehicle. Background technique [0002] In recent years, due to the depletion of energy and the need of environmental protection, the development and application of electric vehicles has become a new hot spot. As a key component of electric vehicles, power batteries play a vital role. The power battery is generally installed in a sealed battery box. Moreover, as the power source of electric vehicles, automotive power batteries are one of the important components of electric vehicles. However, the existing electric vehicle battery box is not only limited in volume, but also has certain defects in its sealing and reasonable installation, and there are also certain structural defects in the components used to connect the battery box and the vehicle frame. Unsafe factors. Contents of the invention [0003] Th...
