The invention provides a transverse buffering type anti-collision beam at the front end of an automobile. The anti-collision beam comprises an arc-shaped main beam, a hollow communicating groove is formed in the middle of the arc-shaped main beam, and edge reinforcing grooves are formed in the two sides of the upper side of the arc-shaped main beam; and the anti-collision beam further comprises a center connecting base which is arranged in the middle of the back face of the arc-shaped main beam, and center connecting rotating shafts are symmetrically arranged on the left side and the right side of the center connecting base. The arc-shaped main beam serves as a collision main beam and is fixed to the automobile main beam through a horizontal fixing beam, when the arc-shaped main beam is collided, the arc-shaped main beam naturally moves to the rear side through rotation and inclination of an outwards-inclined connecting rod and an inwards-inclined connecting rod, the outwards-inclined connecting rod and the inwards-inclined connecting rod are both connected with a compression piston, the compression piston is driven to translate so as to compress air in hollow sealing sleeves to absorb collision kinetic energy, meanwhile, the hollow sealing sleeves can be slidably connected along a horizontal guide sleeve so as to compress horizontal energy absorption boxes arranged between the hollow sealing sleeves, and kinetic energy is further absorbed through crumple deformation of the horizontal energy absorption boxes.

    本公开提供一种汽车前端横向缓冲式防撞梁,包括:弧形主梁,所述弧形主梁的中间设置有中空连通槽,所述弧形主梁的上侧两侧均设置有边缘加强槽;中心连接座,设置于所述弧形主梁的背面中间,所述中心连接座的左右两侧对称设置有中心连接转轴。本发明通过弧形主梁作为碰撞主梁,并通过水平固定梁固定至汽车主梁上,弧形主梁受到碰撞时通过外倾连杆和内倾连杆的转动倾斜自然向后侧移动,而外倾连杆和内倾连杆均与压缩活塞相互连接,可以带动压缩活塞平移以压缩中空密封套筒中的空气吸收碰撞动能,同时中空密封套筒也可以沿水平导向套筒滑动连接,以压缩中空密封套筒之间设置的水平吸能盒,通过水平吸能盒的溃缩变形以进一步吸收动能。
