Safe guard device capable of reducing casualty risk of car crash

Abstract

The invention relates to a buffer horizontal thrust safe guard device capable of reducing casualty risk of car crash. Due to that the car crash between a pedestrian and a car can cause death or injury, the invention provides a safe guard device consisting of a two-stage high pressure cylinder bumper and a front automatic elevation side pushing baffle of a front wheel. The two-stage high pressure cylinder bumper consists of a two-stage high pressure cylinder and an elastic box consisting of a car baffle and a pedestrian baffle, and the car baffle is connected with the two-stage high pressure cylinder. The inner of the box is provided with a spring, a pressure touch switch, and relative self-control circuits arranged in a linkage case. The front automatic elevation side pushing baffle of the front wheel consists of the linkage case, an elevation frame, a side pushing baffle and relative self-control circuits. The invention can reduce the risk of death or serious injury of the pedestrian in front of the car or of the person in the car, as well as reduce the serious machinery damage of the car due to the crash, meanwhile, the pedestrian in front of the car can be pushed to the side of the car automatically after the pedestrian in front of the car is knocked down by the car, thereby reducing the risk of death or serious injury due to the pressing of the wheel. In addition, the device has the characteristics of compact structure, small size, convenient operation, reliable performance, low manufacture cost, energy saving and environmental protection, can meet the requirements of small installation room in the car and the needs for different types of cars, and is convenient for popularization.

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.
