The invention discloses an automobile doorsill with high safety performance, which comprises an inner doorsill, an outer doorsill and a doorsill reinforcing assembly arranged in a mounting cavity formed between the inner doorsill and the outer doorsill, and the doorsill reinforcing assembly comprises a main reinforcing assembly and an auxiliary reinforcing assembly which are matched with each other; the main reinforcing assembly comprises a plurality of supports connected to the inner side of the outer doorsill and main reinforcing beams connected to the supports and arranged in the length direction of the outer doorsill. Through mutual cooperation of multiple energy absorption structures and the counteracting effect of impact force generated by the first arc-shaped crushing plate, the second arc-shaped crushing plate, the crushing inner pipe and the crushing outer pipe, collision energy can be fully absorbed, the impact force to the interior of an automobile during collision is reduced, the side collision resistance of the automobile is greatly improved, and the safety of the automobile is improved.

    本发明公开了一种高安全性能的汽车门槛,包括括内门槛、外门槛以及设置在所述内门槛和所述外门槛之间形成的安装腔内的门槛加强组件,所述门槛加强组件包括相互配合的主加强组件和辅助加强组件;所述主加强组件包括连接在所述外门槛内侧的若干支架以及连接在所述支架上且沿所述外门槛的长度方向布置的主加强梁。本发明中通过多重能量吸收结构相互配合以及第一弧形压溃板、第二弧形压溃板与压溃内管、压溃外管之前产生的冲击力抵消效应,能够充分吸收碰撞能量,降低碰撞时对车内的冲击力,大大提高汽车的抗侧撞性能,提高其安全性。
