Description

Anti-collision buffer device for automobiles

Technical field

The invention relates to automobile parts, and in particular to an anti-collision buffer device for automobiles.

Background technique

Today, with the rapid economic development, cars have entered thousands of households and become a common means of transportation for modern people to go out. But while people are enjoying the high speed and convenience brought by cars, car safety problems are becoming increasingly apparent. Tens of thousands of car accidents occur around the world every year, bringing serious disaster and misfortune to many families.

From the invention of the car to the present, the engine, car body anti-corrosion and comfort have all undergone revolutionary changes compared to the initial stage. However, the car safety protection structure still remains at the level of adding bumpers on the front and rear of the car body, and installing seat belts and airbags in the car. Due to structural problems, the use effect is poor and it cannot effectively prevent injuries to the human body caused by car collisions. The development of society has made humans more and more dependent on cars.

In an embodiment of the present invention, the shape of the first impact plate, the second impact plate, the third impact plate and the fourth impact plate is a circular flat plate structure.

In one embodiment of the present invention, the first air cushion body is formed by wrapping high-strength synthetic rubber along the circumferential direction of the second impact plate and extending to the circumferential direction of wrapping the third impact plate.

In one embodiment of the present invention, the pressure relief layer includes a second air cushion body, and the rated pressure relief valve is connected to the second air cushion body.

In one embodiment of the present invention, the air cushion is formed by wrapping high-strength synthetic rubber along the circumferential direction of the third impact plate and extending to the circumferential direction of wrapping the fourth impact plate.

Compared with the prior art, the beneficial effects of the present invention are as follows:

The anti-collision buffer device of the present invention can be located in the front and/or rear bumper of the vehicle body, or in other parts of the vehicle body. When a collision occurs, the force release layer, the impulse transmission layer and the impulse dispersion layer are all filled in High-pressure gas, after reaching a certain pressure, the anti-collision buffer device will expand to cope with the impact force. The gas can be provided by the built-in compressed high-pressure gas bottle. The anti-collision buffer principle is: when the car collides, the release layer and the impulse are transmitted Both the pressure dispersion layer and the impact dispersion layer are filled with a certain amount of high-pressure gas, and then the anti-collision buffer device is deployed. The pressure relief layer is first squeezed, and the air pressure inside is squeezed to the rated value and then the gas is released to form a buffer. The transfer layer further buffers and transmits the impact force to the impulse dispersion layer. When the impulse dispersion layer is impacted, the carbon fibers at the force-bearing position lose their tightness, and the distance between the two end faces becomes shorter, but the carbon fibers outside the force-bearing position are pulled. At the same time, due to the reduction in volume of the stressed part, the air originally in that position is squeezed to the area outside the stressed position, causing the air pressure in the unstressed position to increase, the volume expands, and the carbon fiber is also stretched. The tension of the stretched carbon fiber increases. When the tension exceeds the maximum value, the greater tension will force the carbon fiber back to its original length and reduce the tension to the equilibrium value, so the volume of the unstressed part will shrink. And squeeze the air toward the stressed part. At this time, the air pressure of the original stressed part will also increase, generating an upward and downward force to disperse the pressure on the stressed surface of the vehicle. Therefore, it has the ability to absorb impact and shock. Therefore, the anti-collision buffer device of the present invention has the advantages of reducing collision damage to the vehicle, minimizing the driver's work risk, and reducing losses caused by accidents and personal casualties.
