The invention provides a collision buffering device. The collision buffering device comprises an outer pipe assembly and an inner pipe assembly. The outer pipe assembly comprises an outer pipe top plate, a top outer taper pipe, an outer pipe middle plate, a bottom outer pipe and an outer pipe bottom plate which are coaxially jointed in sequence. The inner pipe assembly is arranged in the outer pipe assembly and comprises an inner pipe top plate, a top inner pipe and a bottom inner pipe, the top inner pipe and the bottom inner pipe that are coaxially connected in sequence, wherein the top innerpipe and the bottom inner pipe are different in outer diameters. The inner pipe top plate is fixed to the outer pipe top plate; one end of the top inner pipe is jointed with the inner pipe top plate;and one end of the bottom inner pipe is in contact with the outer pipe bottom plate; the sealing pipe of the bottom outer pipe is used as a supporting part at the other end of the bottom inner pipe during collision. When the collision buffering device is impacted by collision, the bottom inner pipe of the inner pipe assembly generates a rolling pipe shrinkage effect to provide an energy absorption effect; the corrugated structure on the surface of the top outer taper pipe of the outer pipe assembly is folded to provide an energy absorption effect.

    本发明提供一种碰撞缓冲装置包括:一外管总成,包括一外管顶板、一顶外锥管、一外管中板、一底外管及一外管底板依序共轴接合;以及一内管总成,设置于该外管总成内,并包括一内管顶板、不同外径的一顶内管及一底内管依序共轴接合,其中:该内管顶板,其与该外管顶板固定;该顶内管的一端与该内管顶板接合;以及该底内管的一端与该外管底板接触,其中该底外管的该封闭管用以作为碰撞时在该底内管的另一端位置的支持部。当受碰撞冲击时,该内管总成的底内管产生翻卷缩管效应以提供吸能效果;该外管总成的顶外锥管表面的波纹状结构折合以提供吸能效果。
