Safe guard device capable of reducing casualty risk of car crash

Abstract

A safety protection device for reducing death and injury risk in vehicle collision is composed of a two-stage high pressure cylinder buffer (1) and an automatic-lifting lateral-pushing baffle (3) in front of a front wheel. The two-stage high pressure cylinder buffer (1) consists of a two-stage high pressure cylinder (5) and an elastic box connected thereto. The elastic box is composed of a vehicle baffle (9) and a pedestrian baffle (10). A spring (Lo), a press switch (k0) and a relative self-control circuit in a linked box (11) are provided in the elastic box. The automatic lifting lateral-pushing baffle (3) in front of the front wheel is composed of the linked box (11), a lifting frame (12, 26), a lateral-pushing baffle (13, 27) and a relative self-control circuit. The safety protection device can reduce not only the danger that pedestrians in front of the vehicle and passengers on board are killed or seriously injured by the vehicle, but also serious mechanical damage of the vehicle resulted from a collision. At the same time, after being knocked down by the vehicle, the pedestrians in front of the vehicle can be automatically pushed to the side of the vehicle, thereby reducing the danger of being killed or seriously injured by wheels.

Description

technical field [0001] The invention relates to the field of electromechanical components installed on automobiles, in particular to a safety protection device for reducing the risk of death and injury in automobile collisions. Background technique [0002] It is well known that the serious defect of the present automobile safety protection device is: only the thicker steel plate or the thicker steel frame of blocking the car have been installed in the front and rear of the automobile, and a part of "weak" structure has been set. Because their deformable size (i.e. buffer distance) is very small and the elapsed time of deformation (i.e. buffer time) is very short, they can only play a small buffering role and can only partially reduce the impact on drivers, Damage to passengers and the main mechanical structure of the car does not reduce the risk of killing, crushing or seriously injuring pedestrians in front of the car. The seat belt in the car can only play a buffering ro...

Problems solved by technology

[0002] As we all know, the serious defect of today's automobile safety protection device is: only the thicker steel plate or thicker steel frame for blocking the car is installed at the front and rear of the car, and some "weak" structures are set.

Because their deformable size (i.e. buffer distance) is very small and the elapsed time of deformation (i.e. buffer time) is very short, they can only play a small buffering role and can only partially reduce the impact on the driver, Damage to passengers and the main mechanical structure of the car will not reduce the risk of killing, crushing, or seriously injuring pedestrians in front of the car

The seat belts in the car can only play a buffer role for the driver and passengers and bring some safety, but they cannot bring any safety to the pedestrians in front of the car.
