The invention belongs to the technical field of automobile parts, and particularly relates to a bumper based on spring energy absorption buffering. The bumper comprises a cross beam, a connecting block, an elastic piece, a supporting piece and a fixing piece; when the cross beam is impacted, impact force is transmitted to the connecting piece and then transmitted to the elastic piece, then the elastic piece is compressed, impact energy is absorbed through deformation of the elastic piece, due to the elasticity characteristic of the elastic piece, the shape of the elastic piece is easily changed in the whole anti-collision beam structure, therefore, the impact energy can be absorbed by the elastic piece firstly, the energy is prevented from being transmitted to other parts, damage to the other parts is prevented, the driving safety is improved, and the maintenance cost after collision is reduced; and meanwhile, through the arranged supporting piece, the stability of the cross beam and the elastic piece is kept under the normal condition, then the cross beam is prevented from shaking in the driving process, the stability of the cross beam is improved, and then the stability of the vehicle structure is improved.
本发明属于汽车配件技术领域,具体的说是一种基于弹簧吸能缓冲的保险杠,包括横梁、连接块、弹性件、支撑件和固定件;本发明中当横梁受到撞击时,冲击力传力到连接件上,进而传递到弹性件上,进而使得弹性件被压缩,进而通过弹性件的变形吸收冲击的能量,由于弹性件本身的弹性的特性,进而在整个防撞梁结构中容易被改变形状,进而使得冲击能量能够率先被弹性件吸收,进而防止能量传递到其他部件上,进而防止其他部件的损伤,进而增加了行车的安全性和减少了碰撞后为维修成本;同时通过设置的支撑件,在正常情况下保持横梁和弹性件的稳定,进而防止横梁在行车过程中的晃动,进而增加了横梁的稳定性,进而增加了车辆结构的稳定性。
