Reusable road anti-collision facility with automatic resetting function
The road anti-collision facility comprises a shell, one end of the shell is open, and a bottom wall is formed on the side, away from the opening, of the shell; a contact part is arranged at one end of the telescopic part, a piston is arranged at the other end of the telescopic part, the piston is inserted through the opening of the shell and is in sliding fit with the shell, and the telescopic part can move from an initial position to the bottom wall in the length direction of the telescopic part under the action of external force; the reset piece is arranged between the shell and the telescopic part, the reset piece is compressed to store force when the telescopic part moves towards the bottom wall, and the reset piece drives the telescopic part to reset towards the initial position after the external force disappears; a buffering cavity is formed between the bottom wall of the shell and the piston, a plurality of through holes communicated with the buffering cavity are formed in the shell, and the buffering cavity is filled with buffering media. The counter-acting force borne by the vehicle at the moment of collision can be reduced, kinetic energy is attenuated through time, and the collision vehicle can be protected.
本发明涉及一种具有自动复位可反复使用的道路防撞设施，包括壳体，该壳体的一端敞口，该壳体远离其敞口的一侧形成底壁；伸缩部，该伸缩部的一端设置有接触部，另一端设置有活塞，该活塞经壳体的敞口处插入并与所述壳体滑动配合，该伸缩部能在外力作用下沿其长度方向从一初始位置向底壁方向运动；复位件，设于壳体和所述伸缩部之间，该复位件在伸缩部向所述底壁方向运动时压缩蓄力，并在外力消失后，带动所述伸缩部向其初始位置复位；所述壳体的底壁和所述活塞之间形成缓冲腔，在所述壳体上设置有多个与所述缓冲腔连通的通孔，且在缓冲腔内填充有缓冲介质。本发明可以降低车辆在撞击瞬间受到的反作用力，利用时间来衰减动能，有利于保护撞击车辆。
