The invention relates to a collision energy absorption mechanism and a vehicle. The collision energy absorption mechanism comprises a fixed support and an energy absorption device installed on the fixed support; the fixed support is made of a metal material; the energy absorption device comprises an energy absorption plunger and a shell; the shell comprises an inner wall and an outer wall which are oppositely arranged, and a side wall is connected between the inner wall and the outer wall; the side wall, the inner wall and the outer wall jointly define a closed hydraulic chamber; one end of the energy absorption plunger is telescopically connected to the interior of the hydraulic chamber and is used for dividing the hydraulic chamber into two cavities, the other end of the energy absorption plunger is arranged outside the hydraulic chamber in a protruding mode, and the energy absorption plunger is provided with a buffer structure capable of enabling oil in the hydraulic chamber to circulate between the two cavities. When oil liquid circulates between the two cavities, kinetic energy is converted into heat energy, collision energy is consumed, and therefore the buffering and energyabsorbing effects can be achieved, and the risk that the life safety of passengers is injured is reduced.
本公开涉及一种碰撞吸能机构和车辆,包括固定支架和安装到该固定支架上的吸能装置,所述固定支架由金属材料制成,所述吸能装置包括吸能柱塞和外壳,该外壳包括相对设置的内壁和外壁,以及连接在所述内壁和所述外壁之间的侧壁,所述侧壁、所述内壁以及所述外壁共同围成封闭的液压室,所述吸能柱塞的一端可伸缩地连接到所述液压室内部,且将所述液压室分隔成两个腔室,另一端凸出设置在所述液压室的外部,所述吸能柱塞上设置有能够使得所述液压室内的油液在所述两个腔室之间流通的缓冲结构。油液在两个腔室之间流通时,将动能转化为热能,消耗碰撞能量,从而能够起到缓冲吸能的作用,降低乘员生命安全受到伤害的风险。
