A kind of integrated multi-stage buffer automobile lower guard plate device and protection method

Abstract

The invention discloses an integrated multi-stage buffer car lower guard plate device and a protection method, comprising a flat plate-shaped first-stage buffer platform and a second-stage buffer platform with step dislocation; The upper curved surface of the lower shield between the buffer platforms; the lower curved surface of the lower shield connected to the second-stage buffer platform; the upper curved surface of the lower shield and the lower curved surface of the lower shield extend from the rear upper to the front downward to form a stepped curved surface; anti-collision On the front surface of the beam, the first-level buffer platform and the front mounting surface of the second-level buffer platform are in the same vertical plane. In the process of collision between cars and pedestrians, it can provide sufficient buffering and support for pedestrians' legs to protect pedestrians; at the same time, it can prevent cars from penetrating into collisions, improve collision compatibility between vehicles, and avoid vicious rear-end collisions. It has the advantages of simple structure, low cost, light weight, high structural strength, good stability, and convenient production and installation.

Description

technical field [0001] The invention relates to the technical field of automobile parts and components, in particular to an integrated multi-stage buffer automobile lower guard plate device and a protection method. Background technique [0002] With the rapid development of my country's automobile industry, the number of automobiles has increased rapidly, resulting in an increasing flow of people and vehicles on the road, increasing the traffic load, and leading to frequent traffic accidents between automobiles and pedestrians. In such accidents, the lower limbs of pedestrians often lack protection measures and are first impacted, causing irreversible damage to pedestrians. [0003] The statistical results of a large number of automobile and pedestrian traffic accidents show that the distribution form and energy absorption of the front end support structure of the vehicle have a greater impact on the pedestrian's leg injury. as attached figure 1 shown (attached figure 1 T...

Problems solved by technology

However, according to the above-mentioned analysis of the APLI leg shape deformation posture, it can be seen that in the collision process between a pedestrian and a car, the existing design of the lower guard plate of the car can neither provide cushioning for the collision of the pedestrian's leg, nor can it provide sufficient protection for the pedestrian's leg. Support to keep it as straight as possible
