The invention relates to a self-resetting uniform energy absorption automobile collision buffering device. The device comprises a foam buffer pad, an anti-collision beam, a buffer rod piece, a concave connecting steel plate, a hydraulic buffer device and a control device. When collision occurs, the foam buffer pad is deformed due to collision, when collision force is transmitted to the anti-collision beam, the four buffer rod pieces connecting the anti-collision beam and the concave connecting steel plate begin to compress downwards to achieve buffering, and meanwhile the inclined buffer rods drive the sliding blocks to compress the damping springs to achieve the supporting effect. A hydraulic buffering device is connected below the concave connecting steel plate and plays a main role in energy absorption and buffering. The automobile collision buffering device is divided into three stages of buffering, and when the collision force is small, the buffering rod piece is enough for effectively resolving the collision force, and damage is reduced; when the collision force is large, the hydraulic buffering device is divided into two stages of buffering, the collision force is effectively and evenly absorbed, the safety of passengers is better protected, self-resetting of the hydraulic buffering device is achieved through a control device and the like, and economical efficiency is improved.

    本发明涉及一种可自复位的均匀吸能汽车碰撞缓冲装置。该装置包括泡沫缓冲垫、防撞梁、缓冲杆件、凹型连接钢板、液压缓冲装置、控制装置。当发生碰撞时,泡沫缓冲垫受到碰撞产生变形,当碰撞力传递到防撞梁时,连接防撞梁和凹型连接钢板的四个缓冲杆件开始向下压缩实现缓冲,同时斜置的缓冲杆带动滑块压缩阻尼弹簧起到支撑作用。凹型连接钢板下面连接液压缓冲装置,起主要的吸能缓冲作用。本发明的汽车碰撞缓冲装置分为三阶段缓冲,碰撞力较小时缓冲杆件足够有效化解碰撞力,减小损伤;碰撞力较大时,液压缓冲装置分为两阶段缓冲,有效实现均匀吸收碰撞力,更好保护乘员安全,通过控制装置等实现液压缓冲装置自复位,提高经济性。
