Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a bumper based on spring energy absorption and buffering. Background technique [0002] The anti-collision beam is a device used to reduce the absorption of collision energy when the vehicle is hit by a collision. It is composed of the main beam, the energy-absorbing box, and the mounting plate connected to the car. The main beam and the energy-absorbing box can effectively absorb when the vehicle collides at a low speed. Collision energy, to minimize the damage of the impact force to the longitudinal beam of the vehicle body, through which it can protect the vehicle. The two ends of the anti-collision beam are connected with low-speed energy-absorbing boxes with low yield strength, and then the The form is connected to the longitudinal beam of the car body. The low-speed energy-absorbing box can effectively absorb the collision energy when the vehicle collides at low speed, ...
