The invention provides a collision buffering energy absorption box and an automobile. The collision buffering energy absorption box comprises a tubular energy absorption box shell, the axis of the energy absorption box shell extends in the front-back direction, and the energy absorption box shell can be of an integrally-formed structure and can also be formed by welding an upper energy absorption box body and a lower energy absorption box body which are both of a U-shaped structure. A plurality of annular concave ribs extending in the circumferential direction of the energy absorption box shell are arranged on the energy absorption box shell and distributed in the axial direction of the energy absorption box shell at intervals, a buffering convex rib is arranged in each annular concave rib, and when the annular concave ribs are collapsed by external force, the buffering convex ribs can play a role in blocking and buffering. The technical problems that when a traditional collision energy absorption box collides, good buffering cannot be achieved, and effective collision energy absorption maximization cannot be achieved are solved.
本发明提供了一种碰撞缓冲吸能盒及汽车,包括呈管状的吸能盒壳体,吸能盒壳体的轴线沿前后方向延伸,所述吸能盒壳体可以是一体化成型结构,也可由均呈U型结构的上吸能盒体与下吸能盒体焊接而成,并在吸能盒壳体上设有多根沿所述吸能盒壳体的周向延伸的环状凹筋,多根所述环状凹筋沿所述吸能盒壳体的轴向间隔分布,每根所述环状凹筋内均设有缓冲凸筋,当环状凹筋受到外力溃缩时,缓冲凸筋能够起到阻挡缓冲的作用。通过本发明解决了传统碰撞吸能盒发生碰撞时不能达到较好的缓冲,无法实现碰撞有效吸能更大化的技术问题。
