Pedestrian protection device for vehicle and automobile

Abstract

The invention discloses a pedestrian protection device for vehicles and a car. The protection device includes a front protective skin, a mounting bracket for supporting the front protective skin, and a front protective energy-absorbing box of the vehicle. The mounting bracket and The energy-absorbing boxes are connected, and the front protective skin covers the mounting bracket. The mounting bracket is an annular structure that runs through the entire width direction of the front end of the vehicle, including an upper buffer plate and a lower support beam. When a collision occurs, the buffer plate disperses the impact energy through its own deformation and collapse to achieve the effect of buffering and energy absorption. The support beam is used to support the weight load of the entire front protective skin. When a collision occurs, the support beam It can move in the direction of impact to reduce the impact of the collision. When a vehicle collides with a pedestrian's leg, the protection device provided by the present invention can effectively unload the impact load on the leg, avoid excessive concentration of force on the leg, and enable the vehicle's front guard to provide better protection for the pedestrian's leg position.

Description

technical field [0001] The present invention relates to the technical field of automobile structure; more specifically, the present invention relates to a pedestrian protection device for a vehicle, and further relates to an automobile including the protection device. Background technique [0002] With the development of automobile technology and the improvement of people's safety awareness, the protection of automobiles is no longer limited to the protection of passengers in the car, but expanded to pedestrians who collide with automobiles. Pedestrians are vulnerable groups in accidents, and injuries to pedestrians' pelvis and legs are often an important cause of pedestrian disability. In the evaluation of vehicle crash safety development standards, the protection of the upper legs of pedestrians has always been a difficult problem. This is mainly because the center of the upper legs of pedestrians impacts the overlapping area between the front edge of the hood and the fron...

AI Technical Summary

Problems solved by technology

Scheme ① can only provide a foundation, and the problems of energy-absorbing space and hard point layout have not been resolved; Scheme ② has limited space for the layout of the engine compartment and front protection, and design changes of multiple parts are not allowed in the middle and late stages of the project; Scheme ③ technical reliability needs to be determined upgrade, the cost is high, and a large number of calibration tests are required, which will also have an impact on the vehicle development cycle
