Anti-collision beam buffering structure with stiffness compensation function

Abstract

The invention belongs to an automobile safety protection device, in particular to an anti-collision beam buffering structure with a stiffness compensation function. The anti-collision beam buffering structure comprises an existing anti-collision beam and buffering devices connected with the existing collision beam through a first fastening buckle, a second fastening buckle, a third fastening buckle and a fourth fastening buckle. The buffering devices each comprise an upper connecting layer, a connecting layer with the buckles for connection, and a lower connecting layer sequentially from top to bottom. The connecting layers with the buckles are constituted by filling layers, and the number of the filling layers is determined by the size of an actual car type anti-collision beam. The connecting layers with the buckles comprise the filling layers with the corresponding number sequentially from top to bottom. The anti-collision beam buffering structure with the stiffness compensation function is simple in structure, convenient to mount, high in applicability and capable of effectively reducing collision impact force, and the problems that as for an existing safety protection structureon the front portion of a car, the anti-impact performance is poor, stiffness is inconsistent, and an anti-collision beam is prone to being damaged are solved.

Description

technical field [0001] The invention belongs to an automobile safety protection device, in particular to an anti-collision beam buffer structure with a rigidity compensation function. Background technique [0002] When a traffic accident occurs, pedestrians are usually in a weak position and are vulnerable to various injuries. Therefore, the bumper system design of the car needs to protect pedestrians. However, the car's front bumper system must also meet the various requirements of the relevant regulations on low-speed collisions. There is a certain contradiction between the two. Therefore, it is very important to take into account the pedestrian protection and the low-speed collision of the car through a reasonable design. [0003] Among the models currently on the market, the safety protection devices at the front and rear of the car are composed of three parts, which are bumper shells, buffer energy-absorbing materials, and anti-collision beams. The cushioning and ene...
