Embodiment

[0034] combine Figure 1-2 , a smart airbag hood for pedestrian protection, which consists of a support layer, a sensing layer, an airbag layer and a protective layer in turn, the airbag layer includes a top airbag 1, a middle airbag and a rear end airbag 3, and the top airbag 1 is set At the front end of the hood, the top airbag 1 is in the shape of a triangular prism, and the right angle side of the top airbag 1 is parallel to the ground and the hypotenuse face faces the victim. The middle airbag includes a middle front-end airbag 21 and a middle rear-end airbag 22. The front end airbag 21 in the middle is triangular prism-shaped and is arranged in front of the hood, the rear airbag 22 in the middle is laid on the upper surface of the hood, and several strip handles 23 are arranged on the rear airbag 22 in the middle. The rear-end airbag 3 is L-shaped and the number is 2, which can be placed on the A-pillar.

Abstract

The invention relates to the technical field of automobile passive safety protection, in particular to an intelligent airbag engine hood for protecting pedestrians and a working method thereof.The intelligent airbag engine hood is sequentially composed of a supporting layer, a sensing layer, an airbag layer and a protective layer. A middle airbag can be wound around or grabbed by a hit person to effectively prevent the hit person from flying out to be injured; if the middle airbag is not wound around or grabbed by a hit person, the engine hood sensing layer monitors the position of the hit person in real time, and it can be guaranteed that when a pedestrian suffers collision by a vehicle, through contact between the hit person and the airbag and movement of the vehicle, inertia energy of impact borne by the hit person is reduced, so that impact force on the ground caused by final falling of the vehicle is reduced, the used technology is mature and reliable, and the engine hood is suitable for large-scale application and popularization, has practical significance and popularization value and is expected to generate good economic benefits.

Description

technical field [0001] The invention relates to the technical field of automobile passive safety protection, in particular to an intelligent airbag engine cover for pedestrian protection and a working method thereof. Background technique [0002] When an automobile collides with a pedestrian or cyclist, the leading cause of death is head injury from the victim. When the collision speed is low, the secondary collision between the victim and the ground may be more serious than the first collision with the car. It can be seen that alleviating the first collision between the victim and the automobile, and the secondary collision with the ground are of great significance for alleviating the injury suffered by the victim. Since most cars are now equipped with AEB (automatic emergency braking), AEB cannot prevent accidents at any time. According to the prediction of IIHS in the United States, AEB can reduce 76% of unbraked corner collision accidents and 69% of unbraked rear-end co...
