The invention discloses an automobile bumper beam assembly structure, an automobile and a collision energy absorption method. The automobile bumper beam assembly structure comprises a lightweight bumper beam main body, an active telescopic energy absorption box and a connecting plate, the upper ends of the pair of active telescopic energy absorption boxes are symmetrically fixed to the lower end faces of the left side and the right side of the light bumper beam body. The lower end of each active telescopic energy absorption box is fixedly connected with a connecting plate; the pair of active telescopic energy absorption boxes can drive the lightweight bumper beam main body to synchronously stretch and retract relative to the connecting plate; the bumper cross beam body is made of light-weight materials, the energy absorption box integrates the active telescopic function at the same time, the distance between the bumper and an anti-collision beam can be adjusted when low-speed collision occurs, and the bumper cross beam has the advantages of being simple in overall structure, high in strength, capable of protecting pedestrians, capable of saving machining and maintenance cost and the like.

    本发明公开了一种汽车保险杠横梁总成结构、汽车及碰撞吸能方法,包括轻量化保险杠横梁主体、主动伸缩吸能盒以及连接板;一对主动伸缩吸能盒上端对称固定于轻量化保险杠横梁主体左右两侧下端面;每个主动伸缩吸能盒下端固定连接有一个连接板;一对主动伸缩吸能盒可带动轻量化保险杠横梁主体相对于连接板同步伸缩;本发明保险杠横梁主体采用轻量化材料,吸能盒同时集成主动伸缩功能,可以在发生低速碰撞时调节保险杠和防撞梁之间的距离,具有整体结构简单、强度高、保护行人,节省加工及维修成本等优点。
