Embodiment Construction

[0023] The present invention as figure 1 shown by:

[0024] The stage where the sensor outputs an electrical signal to the control unit when the sensor senses a collision between the vehicle and the pedestrian;

[0025] The internal output control circuit of the control unit judges the input electrical signal, compares the input value with the set value, and outputs an explosion signal to the inflatable device if it exceeds the set value;

[0026] The inflator explodes after receiving the electrical signal and generates gas through the gas generator to deploy the airbag;

[0027] As the gas is generated and the airbag is deployed, the airbag pushes the outer cover and deploys to the front hood and the front windshield of the vehicle;

[0028] When the airbag is deployed, the force of the airbag deployment is used to push the airbag cover upwards to the front machine cover, so that the end of the front machine cover rotates and rises around the rotating shaft device.

Abstract

The invention provides a method and a safety device for protecting a pedestrian by an automobile at the time of colliding of the pedestrian and the automobile. In the invention, the safety device is arranged on the rear part of a front cover of the automobile, and protects the pedestrian from secondary injury caused by the front cover or a front windshield after the pedestrian is hurt by a bumper when the automobile and the pedestrian collide; an air bag is arranged behind the front cover of the automobile so as to unfold the air bag to play a role in protecting the pedestrian to reduce injury to the pedestrian when the collision happens; the rear side of the front cover rises upwards by other additional measures when the air bag is unfolded, and the pedestrian can fall off towards the outside of the automobile after impact force received by the pedestrian is absorbed by the air bag and the front cover of the automobile so as to protect the pedestrian from the secondary collision. The method and the device can particularly protect the head of the pedestrian from injury.

Description

technical field [0001] The invention relates to a method for a car to protect a pedestrian when a pedestrian collides with a vehicle and a related safety device. The detailed content is to install a safety device behind the front cover of the car to prevent pedestrians from being injured by the bumper when they collide with pedestrians and then receive secondary injuries caused by the front cover or front windshield. A method for protecting pedestrians and related safety devices. Background technique [0002] In order to avoid injury in a collision, a general car is equipped with a bumper that absorbs shock waves, a front hood that covers the engine compartment, and a front windshield that ensures the driver's line of sight and protects the cockpit. [0003] When a vehicle collides with a pedestrian due to inattention while driving, the pedestrian collides with the bumper first and then bounces up due to the forward momentum of the car, and finally the pedestrian collides w...
