The invention discloses a staged energy absorption type automobile collision energy absorption box which comprises an energy absorption box body and energy absorption box mounting bases arranged at the two ends of the energy absorption box body. The energy-absorbing box mounting base comprises a base cavity, a base mounting surface and an energy-absorbing box body mounting hole, the energy-absorbing box body mounting hole is communicated with the base cavity, the energy-absorbing box body mounting hole faces the end part of the energy-absorbing box body, and a connecting surface is arranged at the energy-absorbing box body mounting hole; the two end parts of the energy absorption box body are inserted into the corresponding energy absorption box body mounting holes and are detachably and fixedly connected with the connecting surfaces, so that staged energy absorption is formed; in the first energy absorption stage, only the energy absorption box body participates in energy absorption; and in the second energy absorption stage, the energy absorption box body and the base cavity both participate in energy absorption. The front collision performance and the offset collision performance under the medium-low speed condition can be effectively improved. According to the invention, easy crumpling and staged energy absorption can be realized, and the effects of high energy absorption capacity, light weight, convenience in replacement and maintenance, low cost and the like are achieved.

    本发明公开了一种分阶段吸能式的汽车碰撞吸能盒,包括吸能盒本体,以及设置在吸能盒本体两端的吸能盒安装底座;吸能盒安装底座包括底座空腔、底座安装面和吸能盒本体安装孔,吸能盒本体安装孔与底座空腔连通,且吸能盒本体安装孔面向吸能盒本体的端部设置,吸能盒本体安装孔处设有连接面;吸能盒本体的两端部插设在对应的吸能盒本体安装孔处并与连接面形成可解除式固定连接,从而形成分阶段吸能;第一吸能阶段时,只有吸能盒本体参与吸能;第二吸能阶段时,吸能盒本体和底座空腔都参与吸能。本发明可有效提升中低速情况的正面碰撞和偏置碰撞性能。本发明可实现易溃缩和分阶段吸能,具有吸能量多、重量轻、更换和维修方便且成本低等效果。
