The invention relates to the technical field of automobile safety protection, in particular to an automobile body rear collision energy absorption structure which comprises a buffer shell, a buffer groove is formed in the side face of the buffer shell, two guide plates are symmetrically installed on the side face of the buffer shell, and a reinforcing beam is installed in the buffer groove in the side face of the buffer shell. Tow hook grooves are formed in the upper ends of the reinforcing beam and the buffer shell in a matched mode, a plurality of buffer springs are inserted into the side face of the reinforcing beam at equal intervals, an energy absorption shell is arranged between the two guide plates, rectangular grooves are symmetrically formed in the upper side and the lower side of the energy absorption shell, and two concave guide rails are symmetrically and fixedly connected to the left side and the right side of the energy absorption shell; the automobile energy absorption structure has the beneficial effects that when the rear side of an automobile is collided, a certain energy absorption effect is achieved under the action of the elastic force of the buffer shell and the buffer spring, the energy absorption structure does not deform within a certain collision force, and only the buffer shell and the outer shell need to be maintained and reset in the later period.
本发明公开了涉及汽车安全防护技术领域,具体为一种车身后置碰撞吸能结构,包括缓冲壳,缓冲壳的侧面开设有缓冲槽,缓冲壳的侧面对称安装有两个导向板,缓冲壳侧面的缓冲槽内安装有加强梁,加强梁和缓冲壳的上端相匹配开设有拖车钩槽,加强梁的侧面等距插接有多个缓冲弹簧,两个导向板之间设置有吸能壳体,吸能壳体的上下两侧均对称开设有矩形槽,吸能壳体的左右两侧对称固定连接有两个凹型导轨,矩形槽内卡接有吸能卡块,本发明的有益效果是:当汽车的后侧受到碰撞时,在缓冲壳和缓冲弹簧弹力的作用下起到一定的吸能作用,在一定碰撞力度内,吸能结构不会出现形变,后期只需对缓冲壳、外壳进行维修复位即可。
