The invention discloses a high buffer stroke automobile bumper which comprises a bumper body, a forward energy absorption barrier plate, a lateral barrier plate, an energy absorption buffer plate, an anti-impact assembly and a lateral stabilizing assembly, the bumper body is loaded on the front side of a truck head, and the bumper body is provided with a bumper framework, a front decorative plate and a hinged shaft; wherein the front decorative plate is installed on the front side of the bumper framework, and hinged shafts are arranged on the two side edges of the bumper framework; the forward energy-absorbing barrier plates are distributed on the inner side of the front decorative plate, the forward energy-absorbing barrier plates comprise a plurality of barrier plates, an energy-absorbing layer is arranged on the inner side of each barrier plate, and every two adjacent barrier plates in an end-to-end mode are connected through an energy-absorbing folded plate; the lateral blocking plates are distributed on the two sides of the bumper framework, and the ends, close to the bumper framework, of the lateral blocking plates are movably connected with the bumper framework through multi-degree-of-freedom hinges. Due to the fact that the buffering stroke is high, the instantaneous impact force can be greatly reduced.

    本发明公开了一种高缓冲行程汽车保险杠,包括保险杠本体,正向吸能阻隔板,侧向阻隔板,吸能缓冲板,抗冲击组件与侧向稳定组件,其中保险杠本体装载于货车的车头前侧,保险杠本体具有保险杠骨架、前装饰板与铰轴,其中保险杠骨架前侧安装前装饰板,保险杠骨架两侧边设有铰轴;正向吸能阻隔板分布于前装饰板内侧,正向吸能阻隔板包括多个阻隔板,其中每一阻隔板内侧均设有吸能层,首尾相邻的两阻隔板间通过一吸能折板连接;侧向阻隔板分布于保险杠骨架两侧,侧向阻隔板靠近保险杠骨架的端部通过多自由度铰链与保险杠骨架活动连接。本发明由于缓冲行程较高,因此能大幅减小瞬时冲击力。
