The invention relates to an automobile anti-collision beam and an automobile with the automobile anti-collision beam. The automobile anti-collision beam comprises a front beam and at least one energy absorption box mounted on the front beam and on the side facing the automobile. A rib is arranged in the energy absorption box, the cross section of the rib in the direction perpendicular to the advancing direction of the automobile is in a W shape, the two ends of the W shape are fixed to the two adjacent corners of the energy absorption box respectively, and the vertex of the W shape is fixed to the energy absorption box and located on the side edges where the two ends are fixed. And two bottom points of the W shape are fixed on the side edges opposite to the two adjacent corners. Therefore, the top edge and the bottom edge of the energy absorption box can be provided with stress points except two corresponding adjacent corners, the two stress belts in the middle of the W and the bottom edge of the energy absorption box form a stable triangular structure, and a stable stress surface is constructed together. According to the energy-absorbing box, the hard damage of a cross structure in a traditional energy-absorbing box is avoided, and meanwhile it can be guaranteed that the energy-absorbing box is stable and does not incline.
本发明涉及一种汽车防撞梁及具有所述汽车防撞梁的汽车。汽车防撞梁包括前梁和安装在前梁上且在面向汽车的一侧上的至少一个吸能盒。吸能盒的内部设置有筋,筋在垂直于汽车行进方向上其横截面呈“W”形,且“W”形的两个两端分别与吸能盒的相邻两个拐角处固定,“W”形的顶点固定在吸能盒上且在固定有所述两个两端的侧边上,“W”形的两个底点均固定在与所述相邻两个拐角处相对的侧边上。因而吸能盒的顶边和底边都能有除相应的相邻两个拐角之外的受力点,“W”中间的两条受力带与吸能盒的底边构成平稳的三角形结构,共筑平稳的受力面。本发明既解决传统吸能盒内部的十字交叉结构的硬伤,同时又能保障吸能盒的平稳而不倾斜。
