Abstract

Background
In the prior art, in order to effectively improve the protective effect of the front anti-collision beam and the rear anti-collision beam under low-speed collision of an automobile, automobile energy absorption boxes are generally arranged between the front anti-collision beam and the front longitudinal beam, and between the rear anti-collision beam and the rear longitudinal beam, so that the automobile collision energy is fully absorbed. And the side wall of the automobile energy absorption box is provided with the crumpling groove, so that when the automobile collides forwards, the front anti-collision beam transmits collision energy to the automobile energy absorption box, the automobile energy absorption box absorbs the collision energy through the crumpling deformation of the crumpling groove, the deformation of the longitudinal beam can be reduced, and the safety of personnel in the automobile is guaranteed.
