The automobile anti-collision box comprises two anti-collision boxes, the ends of the two anti-collision boxes are detachably connected with a cross beam, the end, away from the cross beam, of each anti-collision box is detachably connected with a longitudinal beam, and the upper side and the lower side of each anti-collision box are each provided with a plurality of crumple guide grooves in the length direction; a plurality of crumple guide grooves are formed in the two sides of the cross beam, the multiple crumple guide grooves in each side are distributed at equal intervals, connecting columns are fixedly connected to the two ends, located between the two anti-collision boxes, of the surface of the inner side of the cross beam, a connecting plate is welded between the two longitudinal beams, and first connecting holes are formed in the two ends of the connecting plate. When the anti-collision box is subjected to collision force, the anti-collision box can generate wrinkle deformation along the crumple guide groove, the stability of compression deformation is improved, the anti-collision box can stably absorb collision energy, and the buffer spring connected with the cross beam can also play a certain role in buffering collision.

    本发明公开了一种汽车防撞盒及汽车防撞结构,包括两个防撞盒,两个防撞盒的端部拆卸连接有横梁,每个防撞盒远离横梁的一端均拆卸连接有纵梁,防撞盒的上下两侧沿着长度方向均开设有若干个溃缩引导槽,每侧的若干个溃缩引导槽等距分布,横梁的内侧表面且位于两个防撞盒之间的两端固定连接有连接柱,两个纵梁之间焊接有连接板,连接板的两端均开设有一号连接孔,本发明所达到的有益效果包括:本发明的防撞盒上设置有溃缩引导槽,在防撞盒受到碰撞力时,防撞盒会顺着溃缩引导槽产生褶皱变形,提高压缩变形的稳定性,使得防撞盒平稳的吸收碰撞能量,并且横梁连接的缓冲弹簧同样可以起到一定的缓冲碰撞的作用。
