Integrated multi-stage buffer automobile lower protection plate device and protection method

Abstract

The invention discloses an integrated multi-stage buffer automobile lower protection plate device and a protection method. The integrated multi-stage buffer automobile lower protection plate device comprises a tabulate first-stage buffer platform and a tabulate second-stage buffer platform which form step dislocation; a lower guard plate upper curved surface connected between the first-stage buffer platform and the second-stage buffer platform; and a lower guard plate lower curved surface connected to the second-stage buffer platform. The lower guard plate upper curved surface and the lower guard plate lower curved surface extend from the rear upper part to the front lower part to form a stepped curved surface; and the front mounting surfaces of the first-stage buffer platform and the second-stage buffer platform on the front surface of the anti-collision beam are positioned on the same vertical plane. Enough buffering and supporting effects can be provided for the legs of a pedestrianin the process that the automobile collides with the pedestrian, so that the purpose of protecting the pedestrian is achieved; meanwhile, cars can be prevented from drilling and colliding, the collision compatibility between the cars is improved, severe rear-end collision accidents are avoided, the structure is simple, the cost is low, the weight is light, the structural strength is high, the stability is good, and production and installation are convenient.

Description

Technical field[0001]The present invention relates to the technical field of automotive parts structure, and in particular to an integrated multi-stage buffer automotive catalog device and a protective method.Background technique[0002]With the rapid development of my country's auto industry, the number of car insurance has increased rapidly, leading to the growing traffic of road human vehicles, and the transportation load is heavier, which leads to frequent traffic accidents between automobiles and pedestrians. In such an accident, the lower limbs of pedestrians often lack protection measures, first subject to impact, bringing irreversible damage to pedestrians.[0003]The statistical results of a large number of automobiles and pedestrians have shown that the form of support structural distribution in front of the vehicle and the impact of suction resistance on pedestrian leg injury.

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
