The invention relates to the technical field of automobile bumpers, in particular to an automobile bumper buffering device which comprises a mounting frame, a bumper body and a protection assembly, and the protection assembly comprises a hydraulic mechanism, a fixing plate, a buffering column, a buffering spring, an auxiliary part and an air bag mechanism; when a collision occurs, the bumper body is impacted, the hydraulic mechanism on the mounting frame starts to operate, the hydraulic mechanism can be a hydraulic cylinder, the output end of the hydraulic mechanism pushes the fixing plate to move on the buffer column to stretch or compress the buffer spring, meanwhile, the auxiliary part operates on the fixing plate, and the auxiliary part is driven to rotate. According to the air bag type automobile bumper, energy generated by collision of the bumper body can be dispersed to the buffer columns and the fixing plate, the damage degree of an automobile is reduced, and therefore the problems that an existing air bag type automobile bumper only uses two air bags to achieve buffering, the buffering mode is single, and the buffering effect is poor are solved.
本发明涉及汽车保险杠技术领域,具体涉及一种汽车保险杠缓冲装置,包括安装架、保险杠本体和防护组件,防护组件包括液压机构、固定板、缓冲柱、缓冲弹簧、辅助件和气囊机构;在发生碰撞时,保险杠本体受到撞击,安装架上的液压机构开始运转,液压机构可以为液压缸,液压机构的输出端推动固定板在缓冲柱上移动,将缓冲弹簧拉伸或压缩,同时,辅助件在固定板上运转,使得保险杠本体撞击产生的能量能够分散至缓冲柱和固定板上,将保险杠本体撞击产生的能量分散,降低车辆损坏程度,从而解决现有的气囊式汽车保险杠只使用两个气囊实现缓冲,其缓冲方式单一,导致缓冲效果差的问题。
