The invention discloses a high-buffering anti-collision beam energy absorption box which comprises a box bottom plate, energy absorption plates are arranged at the two ends of the box bottom plate, and the energy absorption plates are sunken towards one side to form first collapse grooves; the crumple supporting column is fixed to the box bottom plate, and the top end of the crumple supporting column is slidably connected with an elastic supporting piece matched with the energy absorption plate so as to elastically support one end of the energy absorption plate; the rubber block is arranged on the crumple supporting column in a sleeving mode, and one end of the rubber block makes contact with the elastic supporting piece to support the elastic supporting piece; through the arrangement of the crumple supporting columns, the rubber blocks and the elastic supporting pieces, the situations that the energy absorption box conducts primary buffering on impact only through a bent wall plate, the wall plate is broken towards the bent part after being damaged, and the buffering and energy absorption effect on impact energy is poor are avoided, elastic supporting is conveniently conducted on the first crumple groove, and it is guaranteed that the first crumple groove is not prone to falling off during impact. The positions of the two wall plates are kept unchanged, the continuous energy absorption effect of the two wall plates is improved, and more impact energy can be absorbed.

    本发明公开了一种高缓冲的防撞梁吸能盒,包括:盒底板,所述盒底板两端具有吸能板,且所述吸能板向一侧凹陷形成有第一溃缩槽;溃缩支柱,固定于盒底板上,且所述溃缩支柱顶端滑动连接有与吸能板相配合的弹性支件,以对吸能板一端进行弹性支撑;橡胶块,套设于溃缩支柱上,且所述橡胶块一端与弹性支件相接触对弹性支件进行支撑;通过设置有溃缩支柱、橡胶块及弹性支件,避免吸能盒仅通过弯曲的壁板对撞击进行一次缓冲,在受损后壁板向弯曲部位折损,对撞击的能量缓冲吸能效果不佳,本装置便于对第一溃缩槽处进行弹性支撑,保障在撞击时,保持两壁板的位置不变,提高两壁板对能量的持续吸收效果,且可以吸收更多的撞击能量。
