The invention discloses a novel cavity automobile anti-collision beam energy absorption box, and belongs to the field of automobile anti-collision beam energy absorption boxes. The novel cavity automobile anti-collision beam energy absorption box comprises an energy absorption box body, an energy absorption box cavity, functional reinforcing ribs, a main positioning hole and an auxiliary positioning hole. The energy absorption box body is in a cuboid shape and is formed by extruding aluminum alloy; the energy absorption box body is formed by longitudinally and rigidly connecting three cavities, the upper edge and the lower edge of the energy absorption box body are respectively provided with one functional reinforcing rib, the functional reinforcing ribs are arranged at the central points of the edges and play a role in structural reinforcement in a normal state, and the energy absorption box body is bent from the functional reinforcing ribs during collision so as to absorb impact force. The main positioning hole and the auxiliary positioning hole are formed in the upper top face of the energy absorption box body, and the auxiliary positioning hole is a long and narrow hole and used for adjusting positioning errors. Compared with a traditional anti-collision beam energy absorption box, the novel anti-collision beam energy absorption box has the advantages that not only is the structural form optimized, but also a new material and a new process are used, and the absorption box is a novel anti-collision beam energy absorption box.
本发明公开了一种新式腔体汽车防撞梁吸能盒,属于汽车防撞梁吸能盒领域,包括吸能盒主体、吸能盒腔体、功能性加强筋、主定位孔、辅定位孔,所述吸能盒主体为长方体形状,采用铝合金挤压成型,所述吸能盒主体由三个腔体纵向钢性连接而成,所述吸能盒主体上下四条边各有一个功能性加强筋,所述功能性加强筋布置在边的中心点且在正常状态下起结构加强作,当发生碰撞时吸能盒主体自功能性加强筋处弯曲从而吸收撞击力,所述吸能盒主体上顶面设有主定位孔与辅定位孔,所述辅定位孔为狭长孔,用以调节定位误差,本发明相比传统防撞梁吸能盒不仅仅只在结构形式上进行优化设计,还同时使用新材料新工艺,是一种新形式的防撞梁吸能盒。
