Engine cover for protecting pedestrians for intelligent automobile and working method of engine cover

Abstract

Aiming at the fact that most of in existing research results, only human-vehicle collision damage is protected, the invention designs an engine cover for protecting human-vehicle and human-ground collision damage. The engine cover consists of a supporting layer, an air bag layer and a protective layer, wherein the air bag layer comprises three hedgehog-shaped air bags. When an accident is detectedto be unavoidable, the air bag layer is detonated and completely brakes until the head of a human body collides with a vehicle body for the first time, the speed of the vehicle is controlled to enable the rear edge of the engine cover to keep a certain distance from the chest of the human body and the engine cover and the human body move together, and when the human body collides with the enginecover again, the air bag layer completely brakes again until the human body is in a fixed state. The engine cover has the beneficial effects that by detonating the air bag layer, the hedgehog-shaped air bags cover a vehicle head so as to reduce human-vehicle direct collision force, and meanwhile, the ejection speed of a pedestrian is reduced by barb-shaped air columns; and the vehicle head catchesthe human body by moving the vehicle, and the falling speed of the human body is reduced by the air columns on the outer surfaces of the air bags to further consume potential energy and kinetic energy of the human body, so that human-ground collision speed is reduced, and human-vehicle collision protection and human-ground collision protection are realized simultaneously.

Description

technical field [0001] The invention relates to the field of smart cars, more specifically, to an engine cover for smart cars to protect pedestrians and a working method thereof. Background technique [0002] Because pedestrian accidents are closely related to the travel of almost everyone and are fatal injuries to the weak by the strong, this type of accident has become the focus of public opinion. Compared with the occupants in the vehicle, pedestrians suffer more serious injuries in traffic accidents, so it is extremely necessary to study measures to protect pedestrians. [0003] The injuries of pedestrians in traffic accidents mainly come from the first collision with the vehicle body and the second collision with the ground afterwards. Generally speaking, car body collision is the main cause of human injury, but human injury from the ground cannot be ignored. At present, the research focuses on the protection of damage caused by the car body. Scholars have proposed a ...
