The invention discloses an automobile anti-collision beam which comprises an anti-collision beam body, T first inner hole sets are formed in the anti-collision beam body in the vertical direction at intervals, each first inner hole set comprises M first inner holes formed in the front-back direction at intervals, and a second inner hole set is arranged between every two adjacent first inner hole sets. Each second inner hole group comprises N second inner holes, T is greater than or equal to 2, M is greater than or equal to 2, N is equal to M-1, and the positions of the N second inner holes and the M first inner holes are staggered in the front-back direction; the M first inner holes and the N second inner holes are communicated in the left-right direction. Force and energy generated by collision can be diffused to the whole anti-collision beam body, and the rigidity and strength of the automobile anti-collision beam are effectively improved.
本发明公开了一种汽车防撞梁,包括防撞梁主体,所述防撞梁主体的内部沿上下方向间隔设置有T个第一内孔组,每个所述第一内孔组均包括M个沿前后方向间隔设置的第一内孔,相邻两个所述第一内孔组之间分别设置有一个第二内孔组,每个所述第二内孔组均包括N个第二内孔,其中T≥2,M≥2,N=M‑1,并且N个所述第二内孔与M个所述第一内孔在前后方向上的位置均错开;M个所述第一内孔和N个所述第二内孔均沿左右方向贯通。本发明能够将碰撞产生的力和能量发散至整个防撞梁主体,有效提高汽车防撞梁的刚度及强度。
