The invention relates to the technical field of automobiles, and discloses an automobile anti-collision buffering device which comprises a shell, a sliding base, a first piston and a second piston. An oil passing channel, a first piston hole and a second piston hole are formed in the shell, the first piston is arranged in the first piston hole, the second piston is arranged in the second piston hole, and when the buffering end cover is subjected to first collision acting force, the buffering end cover and the sliding seat cooperatively move downwards by a first preset distance; when the buffering end cover is subjected to a second collision acting force, the buffering end cover and the sliding seat cooperatively move downwards, and the elastic piece is compressed; when the buffering end cover is subjected to third collision acting force, the oil storage cavity is communicated with the oil passing channel, so that oil in the oil storage cavity flows into the oil passing channel, and the upper seat body abuts against the first piston firstly and then abuts against the second piston. The automobile anti-collision buffering device has the advantages that buffering and energy absorption are achieved through cooperation of machinery and hydraulic pressure, and the buffering effect is good through multi-stage buffering and energy absorption.
本发明涉及汽车技术领域,公开一种汽车防撞缓冲装置,包括:壳体、滑座、第一活塞和第二活塞,滑座和壳体围成一储油腔;壳体中设有过油通道、第一活塞孔和第二活塞孔,第一活塞设置在第一活塞孔中,第二活塞设置在第二活塞孔中,当缓冲端盖受到第一碰撞作用力时,缓冲端盖和滑座协同向下运动第一预设距离;当缓冲端盖受到第二碰撞作用力时,缓冲端盖和滑座协同向下运动,并压缩弹性件;当缓冲端盖受到第三碰撞作用力时,储油腔与过油通道连通,以使储油腔的油液流至过油通道中,上座体先与第一活塞相抵,后与第二活塞相抵。本发明的优点在于,本汽车防撞缓冲装置通过机械与液压协同缓冲吸能,通过多级缓冲吸能,缓冲效果好。
