An anti-collision beam assembly comprises an anti-collision cross beam, a first energy absorption box and a second energy absorption box, wherein the first energy absorption box and the second energyabsorption box are arranged at the two ends of the anti-collision cross beam respectively, the first energy absorption box and the anti-collision cross beam are rotatably connected through a first rotating shaft, and the second energy absorption box and the anti-collision cross beam are rotatably connected through a second rotating shaft. When the anti-collision beam assembly collides, the anti-collision cross beam and the first energy absorption box or the second energy absorption box form a revolute pair, the peak force at the initial moment of collision is reduced, and the tearing failure risk of the first energy absorption box and the second energy absorption box is reduced.
一种防撞梁总成,包括防撞横梁、第一吸能盒和第二吸能盒,第一吸能盒和第二吸能盒分别设置于防撞横梁的两端,第一吸能盒与防撞横梁之间通过第一转轴实现可转动地连接,第二吸能盒与防撞横梁之间通过第二转轴实现可转动地连接。本发明的防撞梁总成发生碰撞时,防撞横梁与第一吸能盒或第二吸能盒形成转动副,降低碰撞初始瞬间的峰值力,降低第一吸能盒和第二吸能盒撕裂失效风险。
