The invention relates to the technical field of vehicle energy absorption, in particular to an automobile safety collision energy absorber which is characterized in that a supporting frame is mounted on a vehicle through a mounting head, a cross rod of an energy absorption assembly is mounted at the front end of the supporting frame and used for bearing impact from the front, two inclined rods are arranged on the two sides of the cross rod, and impact from the two sides is absorbed through the two inclined rods; when the inclined rod is impacted, the force is decomposed into the transverse direction and the longitudinal direction, the transverse force of the inclined rod is absorbed through the spring set, the longitudinal force of the inclined rod pushes the sliding rod, and therefore the sliding rod pushes the hydraulic cylinder to contract so that hydraulic oil can be pressed into the oil return tank, the longitudinal force is absorbed, and the oil return effect is improved. And hydraulic oil in the oil return tank is adjusted through the stroke adjuster, so that the hydraulic oil in the oil return tank is actively fed into the hydraulic cylinder when it is judged that the hydraulic oil is impacted, the inclined rod and the cross rod are pushed out by a certain distance, and therefore the buffering distance is increased, the buffering energy absorption effect is improved, and use is safer.

    本发明涉及车辆吸能技术领域,具体涉及一种汽车安全碰撞吸能器,通过安装头将支撑架安装到车辆上,吸能组件的横杆安装到支撑架的前端,用于承受来自正前方的冲击,在横杆的两侧设置有两个斜杆,通过两个斜杆吸收来自两侧的冲击,在斜杆受到冲击时的力分解为横向和纵向两个方向,斜杆横向的力通过弹簧组进行吸收,斜杆在纵向的力则推动滑杆,从而通过滑杆推动液压缸的液压缸收缩以将液压油压入到回油箱中,以对纵向的力进行吸收,通过行程调节器对回油箱中的液压油进行调整,使得在判断会受到冲击时主动将回油箱中的液压油送入到液压缸中,将斜杆和横杆推出一定距离,从而增加缓冲距离,提高缓冲的能量吸收效果,使得使用更加安全。
