Abstract

The invention discloses a buffer energy-absorbing bumper, comprising a shell and a bumper collision rod which is erected at the front side of the shell through a plurality of energy-absorbing mechanisms. Each energy-absorbing mechanism comprises a first longitudinal energy-absorbing spring, two horizontal energy-absorbing springs, two fixed baffles, two sliding blocks and two dowel bars, wherein the front end of the first longitudinal energy-absorbing spring is connected with the bumper collision rod, and the rear end of the first longitudinal energy-absorbing spring is connected with the rear end of the shell; the two horizontal energy-absorbing springs are arranged at the rear end of the shell and are respectively positioned at two sides of the first longitudinal energy-absorbing spring; the two fixed baffles are arranged at the rear end of the shell and are respectively connected with one ends, far away from the first longitudinal energy-absorbing spring, of the two horizontal energy-absorbing springs; the two sliding blocks are arranged at the rear end of the shell and are respectively connected with the other ends of the two horizontal energy-absorbing springs; and the rear ends of the two dowel bars are respectively articulated with the two sliding blocks, and the front ends of the two dowel bars are articulated to the bumper collision rod. According to the invention, the collision force is decomposed by the longitudinal energy-absorbing springs and the horizontal energy-absorbing springs so as to realize shock absorption and energy absorption, thereby improving the safety performance of the bumper.

Description

technical field [0001] The invention relates to the field of automobile bumpers, in particular to a buffer energy-absorbing automobile bumper. Background technique [0002] With the improvement of people's living standards, more and more families have cars, and the safety of cars has attracted everyone's attention. The bumper on the car is the first to touch the obstacle when the car collides, so the safety of the car is inseparable from the bumper. The bumper of a car is generally made of plastic or thin metal, and the insurance factor is generally not high. In order to improve the insurance factor of the bumper, most of the methods used are to widen and thicken the bumper, but in the event of a collision The bumper and the obstacle are still head-to-head, the bumper cannot effectively absorb the collision energy, the risk is still very large, and the widened or thickened bumper also increases the weight of the car. [0003] The information disclosed in this Background se...
