The invention provides a squeezing buffer type anti-collision beam at the front end of an automobile. The anti-collision beam comprises a bow-shaped main beam and a horizontal fixing frame, wherein connecting clamping bases are symmetrically arranged on the left side and the right side of the back face of the bow-shaped main beam, connecting rotating shafts are arranged in the middles of the connecting clamping bases, the horizontal fixing frame is arranged on the rear side of the bow-shaped main beam in parallel, and guide sliding grooves are symmetrically formed in the left side and the right side of the horizontal fixing frame. The bow-shaped main beam serves as the collision main beam and is fixed to the automobile main beam through the horizontal fixing frame, the bow-shaped main beam and the horizontal fixing frame are connected through a telescopic guide rod and a telescopic guide cylinder, and the bow-shaped main beam can move towards the rear side to enable the telescopic guide rod and the telescopic guide cylinder to slide relatively in the collision process so that a circular sliding block can slide in the telescopic guide cylinder, a plurality of elastic blocking rings arranged in the telescopic guide cylinder can block the circular sliding block, the circular sliding block can extrude the elastic blocking rings through inclined contact surfaces, energy is buffered and absorbed through deformation fracture of the elastic blocking rings, and the buffering force is more uniform.
本公开提供一种汽车前端挤压缓冲式防撞梁,包括:弓型主梁,所述弓型主梁的背面左右两侧对称设置有连接卡座,所述连接卡座的中间设置有连接转轴;水平固定架,平行设置于所述弓型主梁的后侧,所述水平固定架的左右两侧对称设置有导向滑槽。本发明通过弓型主梁作为碰撞主梁,并通过水平固定架固定至汽车主梁上,而弓型主梁与水平固定架之间通过伸缩导向杆和伸缩导向筒相互连接,受到碰撞时弓型主梁可以向后侧移动使伸缩导向杆和伸缩导向筒相对滑动,进而带动圆形滑块在伸缩导向筒中滑动,而伸缩导向筒中设置的多个弹性阻挡环会阻挡圆形滑块,圆形滑块通过倾斜接触面可以挤开弹性阻挡环,通过弹性阻挡环的变形断裂缓冲吸能,缓冲力度更加均匀。
