The invention discloses a telescopic front-end anti-collision structure, and relates to the technical field of automobile protection equipment, the telescopic front-end anti-collision structure comprises an anti-collision beam, two identical energy absorption boxes and a frame, the two identical energy absorption boxes are fixedly arranged on the inner side of the anti-collision beam, the anti-collision beam is fixedly connected with the energy absorption boxes, the energy absorption boxes and the frame have a relative sliding relation, and in a locking state, the anti-collision beam is fixedly connected with the energy absorption boxes. The energy absorption box can play a role in supporting the anti-collision beam and also can participate in energy absorption, so that the rigidity and the strength of a high-speed head-on collision working condition are realized; and meanwhile, when a sensor detects the pedestrian protection working condition, a lock pin in the unlocking mechanism pushes a lock hook to unlock, an energy absorption box and a frame are unlocked, through front end size shrinkage, harm to the shanks of pedestrians is reduced, high-speed head-on collision and pedestrian protection collision are met, and the contradiction point of the front end anti-collision safety requirement for the performance requirement of the front end anti-collision structure is solved.
本发明公开了一种可伸缩的前端防撞结构,涉及汽车防护设备技术领域,它包括:防撞梁、吸能盒、车架,两个相同所述的吸能盒分别固定设置在防撞梁内侧,所述的防撞梁与吸能盒固连,吸能盒与车架存在相对滑动关系,在锁止状态下,吸能盒能起到对防撞梁的支撑作用,也能够参与吸能,实现高速正面碰撞工况的刚度和强度;同时在传感器检测到行人保护工况时,解锁机构内部锁销推动锁钩解锁,吸能盒与车架解锁,通过前端尺寸收缩,降低行人小腿伤害,满足高速正面碰撞和行人保护碰撞,解决了基于前端防撞安全要求对前端防撞结构性能需求的矛盾点。
