Description

Pedestrian collision protection device and automobile

Technical Field

The utility model relates to the technical field of automobiles, in particular to a pedestrian collision protection device and an automobile.

Background

With the development of the automobile industry, an automobile safety protection device has become an important part of automobile design, and in the past, only the protection of passengers by an automobile is often considered in automobile design, but the protection of vulnerable groups such as pedestrians is ignored; in the process of collision with a pedestrian when an automobile is driven, a front bumper of the automobile is the most main structure for collision with the lower leg of the pedestrian.

Some automobiles have higher chassis, so that the front bumpers of the automobiles are also arranged higher, for example, when an off-road vehicle/common vehicle with the bottom of the front bumper of the automobile having a ground clearance of 400-600mm runs in a city, pedestrians on the city are more, sometimes the off-road vehicle/common vehicle with the higher chassis cannot avoid colliding with the pedestrians, and the off-road vehicle/common vehicle often has untimely braking and too high chassis, so that the legs of the pedestrians are rolled into the bottoms of the vehicles when the off-road vehicle/common vehicle collides with the pedestrians, the pedestrians are easily rolled, and the lives of the pedestrians are seriously endangered; if the chassis of the off-road vehicle/common vehicle is arranged low, the running of the off-road vehicle/common vehicle in hilly areas and desert areas is influenced, so that the off-road vehicle/common vehicle cannot achieve both an urban running mode and an off-road mode for protecting pedestrians.
