Automobile safety protection device

Abstract

The invention relates to the technical field of automobile safety and discloses an automobile safety protection device. The automobile safety protection device comprises an automobile body, an underpan, a front bumper, a rear bumper and an air bag, a hollow cylinder, an air cylinder and a rolling ball are arranged on the underpan, a slide bar is slidably mounted on the hollow cylinder, a first gear rack meshed with a first gear is arranged on the slide bar, the first gear is coaxially connected with a second gear, a piston rod slidably penetrates through the air cylinder, a second gear rack meshed with the second gear is arranged on the piston rod, an air outlet is formed in one end of the air cylinder, and the air outlet and the air bag are connected with a vent tube. When an automobile brakes urgently, the rolling ball rolls to push the slide bar to slide, and through matching of the first gear rack, the first gear, the second gear and the second gear rack, the piston rod is enabledto push a piston in the air cylinder to move, so that that air cylinder can inflate the air bag. When crashes of the automobile happen, the inflated air bag can buffer and protect the automobile bodyor passengers.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automobile safety protection device. Background technique [0002] The problem of automobile collision safety has attracted more and more attention in today's society. With the increase of automobile ownership year by year, the incidence of automobile rear-end collision accidents and human-vehicle collision accidents is also showing an upward trend. In the process of automobile collision, the highest probability of occurrence is The most important is the collision of the front of the car, which mainly involves the collision of the front bumper. Common car front bumpers are generally plastic bumpers at present, and the exterior is sprayed with a layer of paint. [0003] In the process of driving a car, the driver will inevitably encounter emergencies and be forced to brake urgently, which will easily cause rear-end collisions with the following vehicles.

Problems solved by technology

[0003] In the process of driving a car, the driver will inevitably encounter emergencies and be forced to brake urgently, which will easily cause rear-end collisions with the following vehicles. The overall aesthetics of the car; if the collision is serious, it will cause the car bumper to be dented and deformed, so that the owner needs to replace the whole car bumper, the maintenance cost is high, and it also delays the daily use of the car

If a car collides with a pedestrian, although the front bumper of the car is made of plastic, the impact force of the car itself will still cause injury to the pedestrian and cause damage to the car itself
