The invention discloses an energy absorption device for a front anti-collision beam of an automobile, and relates to the technical field of automobile anti-collision. Comprising a barrel shell, a sliding opening is formed in the side, away from a beam body, of each barrel shell, an inner connecting pipe is slidably connected between the inner walls of the sliding openings, and a supporting spring is fixedly connected to the end, facing the interior of the corresponding barrel shell, of each inner connecting pipe. Through the arrangement of the impact cylinder, when the impact cylinder is impacted, air, separated by the ventilation pipe and outside air, in the cylinder shell is compressed, the plug body is jacked up through air pressure, and therefore energy contained in the impact is converted into acting on the air and the ventilation spring, and the energy absorption effect is achieved; the rigid beam body is prevented from being directly impacted to generate large-amplitude distortion, so that the vehicle body is protected; and meanwhile, through the arrangement of the connecting anti-collision beam, the impact force is uniformly conducted into the automobile body through the arrangement of the apportionment supporting legs when the automobile body is impacted, so that the automobile body is prevented from deforming under the impact to a certain extent.

    本发明公开了一种汽车前防撞梁吸能装置,涉及汽车防撞技术领域。包括一个筒壳,每个所述筒壳远离梁体的一侧开设有滑口,每个所述滑口的内壁之间皆滑动连接有一根内接管,每个所述内接管朝向对应筒壳内部的一端皆固定连接有一根支撑弹簧。本发明通过冲击筒的设置,在受到冲击时,将筒壳中被通气管和外界空气分隔的空气被压缩,通过气压将塞体顶起,从而将冲击中蕴含的能量转化为对空气和通气弹簧的做功,从而起到吸能的效果,避免刚性的梁体直接受到冲击而产生较大幅度的扭曲,从而保护车体;同时,通过连接防撞梁的设置,在受到冲击时利用分摊支脚的设置,将冲击力较为均匀的传导至汽车车体中,从而在一定程度上防止汽车车体在冲击下变形。
