The invention discloses a buffering energy absorption box which is manufactured by expanding and stretching a pipe and comprises a rear cylindrical pipe section, a front cylindrical pipe section and a transition section, the rear cylindrical pipe section and the front cylindrical pipe section are integrally formed, the transition section is connected with the rear cylindrical pipe section and the front cylindrical pipe section, and the pipe wall thickness of the front cylindrical pipe section is larger than that of the rear cylindrical pipe section. The thickness of the pipe wall of the rear cylindrical pipe section is reduced relative to the thickness of the pipe wall of the front cylindrical pipe section, when the buffering energy absorption box is subjected to axial pressure, a material deforms in the first stage and the second stage, and the energy absorption efficiency is high.

    本发明公开了一种缓冲吸能盒,由管材通过涨形拉伸制得,包括一体成型的后圆柱管段、前圆柱管段以及连接所述后圆柱管段与所述前圆柱管段的过渡段,所述前圆柱管段的管壁厚度大于所述后圆柱管段的管壁厚度。本发明后圆柱管段相对前圆柱管段的管壁厚度减薄,当缓冲吸能盒受到轴向的压力时,材料发生第一阶段、第二阶段的形变,吸能效率高。
