One or more embodiments of the invention provide a bumper anti-collision structure, which comprises an outer plate, a buffer layer is attached to the inner side of the outer plate, an energy absorption cavity is fixed to the inner side of the outer plate, a plurality of movable shafts are arranged at the end, facing the outer plate, of the energy absorption cavity at intervals in a penetrating mode. Elastic folded plates are fixed to the two sections of each movable shaft respectively, and the elastic folded plates penetrate out of the front end of the energy absorption cavity, and in the initial state, the elastic folded plates expand in a splayed shape. Meanwhile, the two ends of each movable shaft penetrate out of the side ends of the energy absorption cavity and are coaxially and fixedly provided with driving gears correspondingly, the middles of the adjacent driving gears are connected with driven gears in a meshed mode, the middles of the elastic folded plates on the different sides of the adjacent movable shafts are connected with movable connecting parts, and when the outer plate is impacted, the elastic folded plates are pushed and pressed to turn and deform. The elastic folded plates in the lateral direction are synchronously driven to fully participate in buffering and crumple energy absorption together and compress and store air together, so that the air is slowly overflowed and released through a throttling valve, and the buffering and crumple energy absorption effects are further greatly improved.

    本说明书一个或多个实施例提供一种保险杠防撞结构,包括外板,外板内侧贴合设有缓冲层,外板内侧固定有吸能腔,吸能腔朝向外板一端间隔排列穿设有若干个活动轴,活动轴两段上分别固定有弹性折板,弹性折板贯穿出吸能腔前端,且初始状态下呈外扩的八字形展开,同时活动轴两端贯穿出吸能腔侧端,并分别同轴固定有主齿轮,相邻的主齿轮中间啮合连接有从齿轮,相邻活动轴上不同侧的弹性折板中间连接有活动连接部,外板受撞击时,以推压弹性折板转向变形,且一并同步传动侧向的各弹性折板共同充分参与缓冲和溃缩吸能,并共同压缩储气,以经由节流阀缓慢溢流释放出气,以进一步较大的提升缓冲和溃缩吸能功效。
