The invention relates to an electric truck battery multi-level protection device, which can solve the problem that the electric truck battery is deformed due to strong physical extrusion when being collided, and finally causes fire or even explosion in the prior art. The technical scheme comprises a box body, a shell body inside the box body, a battery pack inside the shell body, vertical plates on the left and right sides of the shell body, a first vertical plate on the inside of the vertical plate, a second vertical plate on the outside of the vertical plate, a third vertical plate on the outside of the second vertical plate, and push rods on the outside of the third vertical plate. The box body is provided with a rotating shaft, the rotating shaft is provided with a rotating block, therotating block is provided with a positioning hole, the rotating block is provided with a guide groove, the rotating shaft can be fixed, the second vertical plate is provided with a guide rod, the third vertical plate can make the fixing device loosen the rotating shaft, the guide groove is horizontal, and the guide rod moves along the guide groove. The second vertical plate is moved to release the vertical plate. The vertical plate is moved to release the first vertical plate, and the first vertical plate drives the shell to move out of the box. The multi-stage collision avoidance of the battery pack in the shell can be realized, and a good collision avoidance effect is achieved.
Description
technical field [0001] The invention relates to the field of battery protection for electric trucks, in particular to a multi-stage battery protection device for electric trucks. Background technique [0002] In recent years, the global smog and greenhouse effect caused by fossil fuels have seriously affected the sustainable development of the traditional truck industry, so electric trucks have become a development trend. Different from traditional trucks, the collision safety performance of electric trucks should not only consider the protection of the passengers, but also the protection of the power battery; the power battery is relatively large and is usually arranged at the bottom of the electric truck; when an electric truck collides In the event of an accident, the power battery may be short-circuited due to extrusion and deformation, causing fire or even explosion. [0003] In the prior art, some methods of power-off or airbag protection are used to protect the power...
