The invention discloses an automobile front end energy absorption structure with collision compatibility and an automobile, and belongs to the field of automobile bodies. A vehicle receives a collision signal through a front collision sensor in the front end energy absorption structure, collapse holes are formed in energy absorption boxes, indentations are formed in the front ends of front longitudinal beams, and reinforcing beams are additionally arranged at the rear ends of the front longitudinal beams, so that the energy absorption boxes and the longitudinal beams can be sequentially crushed from front to back, the energy absorption efficiency is improved by 20% compared with a traditional steel front anti-collision beam, and the weight is reduced; the main energy absorption box with the crumple holes and the front longitudinal beam with the process indentations can serve as a first force transmission path to fully crumple and absorb energy. The shank lower supporting assembly is installed at the front end of the front auxiliary frame and can serve as a second force transmission path for collision energy absorption, the front end can be bent and upwarped in the collision process, and the collision acceleration peak value is effectively reduced. And the lower support can be used as a lower support for protecting legs of pedestrians, so that C-shaped bending of the legs is avoided, and the injury value of the legs of the pedestrians outside the vehicle is effectively reduced. Therefore, the problems in the prior art can be solved.

    本发明公开了一种具有碰撞兼容性的汽车前端吸能结构及汽车,属汽车车身领域。车辆通过前端吸能结构中的前碰传感器接受碰撞信号,通过在吸能盒上设置溃缩孔、前纵梁前端设置压痕、前纵梁后端增加补强梁,可实现吸能盒、纵梁从前到后的依次压溃,吸能效率相对传统钢制前防撞梁提升20%,重量降低,具备溃缩孔的主吸能盒及工艺压痕的前纵梁可作为第一条传力路径充分溃缩吸能。小腿下支撑总成安装于前副车架前端,既可以作为碰撞吸能的第二条传力路径,可实现碰撞过程中前端折弯上翘,有效降低碰撞加速度峰值;又可以作为行人保护腿部的下支撑,避免腿部“C”字形弯折,有效降低车外行人的腿部伤害值。因此本发明能够解决现有技术存在的问题。
