Automotive chassis anti-collision mechanism and electric automobile

The vehicle chassis anti-collision mechanism comprises a hollow beam arranged on a chassis and an anti-collision assembly installed in the hollow beam, and the anti-collision assembly comprises an anti-collision buffer layer and an anti-collision reinforcing block set which are arranged in the hollow beam; the hollow beam triggers the anti-collision reinforcing block set by making contact with the anti-collision buffering layer in the collision process so as to relieve vehicle collision impact. According to the automotive chassis anti-collision mechanism and the electric automobile, a special collision protection scheme is adopted, the rigidity and strength of the chassis are improved and the collision deformation is reduced by changing the arrangement mode of the anti-collision reinforcing blocks in the chassis on the premise that the weight of an automobile body and the weight of a battery are not increased, meanwhile, the collision reinforcing blocks are easy to replace and reset, and the cost is reduced.
