Description

A three-stage automobile collision buffer device

technical field

The utility model belongs to the technical field of passive safety protection of motor vehicles, in particular to a buffer protection device which can play a buffer protection function when a vehicle collides with the rear, front or side.

Background technique

With the continuous increase of car ownership, roads are becoming more and more congested, road conditions are becoming more and more complex, traffic accidents occur frequently, and various collision accidents are common, the passive safety performance of cars is becoming more and more important. Existing passive safety protection for automobiles mainly includes seat belts, airbags, bumpers, etc., but the protective effect of these devices in actual accidents is very limited. At present, most of the passive safety protection measures of vehicles are to absorb the impact by damaging the front of the car, so as to reduce personal injuries. Therefore, the problem in the prior art is: in order to ensure the safety of drivers and passengers, when the vehicle collides, the vehicle is seriously damaged.

Contents of the invention

The utility model can effectively resolve the impact force generated in the collision process of the automobile, reduce the damage degree of the vehicle, protect the safety of the occupants, has low manufacturing cost, and is effective and practical.

The technical solution adopted by the utility model to solve the technical problem is: a three-stage automobile collision buffer device, which can be installed in the parts where the automobile is prone to collision, such as the front, rear and side positions of the car, from right to left It consists of a rubber layer, an airbag layer and a spring layer. The rubber layer is glued together with the airbag. The airbag layer and the spring layer are fixedly connected together by using bolts. The airbag layer is equipped with two pressure-limiting holes in the parts prone to collision, such as the rear end or the door, and is controlled by the pressure-limiting opening mechanism here. When the pressure in the airbag layer reaches the preset predetermined value, the pressure-limiting mechanism opens and the airbag The gas in the gas enters the pressure limiting hole through the air holes on both sides of the pressure limiting mechanism, is discharged into the spring layer, and is discharged through the exhaust holes on both sides of the spring layer. The thickness of the rubber layer is 30-50mm.

The pressure-limiting opening mechanism at the pressure-limiting hole of the airbag layer is composed of a pressure-relieving spring and a pressure-relieving plug, the pressure-relieving plug blocks the pressure-limiting hole, and the pressure-releasing spring supports the pressure-relieving plug behind the pressure-relieving plug.

The airbag layer is provided with an inflation valve.

The spring layer is provided with 16 springs in total, which are fixedly connected with the air bag layer by bolts, and vent holes are arranged on both sides of the spring layer.

Both the rubber layer and the airbag layer are made of tire rubber, which is a relatively common material, can be made from recycled old tire rubber, has low cost, and can be used repeatedly.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1, the utility model is a three-stage buffer device for alleviating collisions of automobiles, consisting of a rubber layer, an air bag layer, and a spring layer. side position. From right to left, there are rubber layer, airbag layer and spring layer. The rubber layer and airbag layer are glued together through adhesive connection. The airbag layer is equipped with two pressure-limiting holes in the parts prone to collision, such as the rear end or the door, and is controlled by the pressure-limiting opening mechanism here. When the pressure in the airbag layer reaches the preset predetermined value, the pressure relief plug is lifted. , the pressure relief spring is compressed, that is, the pressure limiting mechanism is opened, and the gas in the airbag enters the pressure limiting hole through the air holes on both sides of the pressure limiting mechanism, enters the spring layer, and is discharged through the exhaust holes on both sides of the spring layer.

The thickness of the rubber layer is 30-50mm.

The pressure limiting opening mechanism at the pressure limiting hole of the airbag layer is composed of a pressure relief spring and a pressure relief plug, and the airbag layer is provided with an inflation valve.

The pressure relief plug blocks the pressure limiting hole, and the pressure relief spring supports the pressure relief plug behind the pressure relief plug.

The spring layer is provided with 16 springs in total, which are fixedly connected with the air bag layer by bolts, and vent holes are arranged on both sides of the spring layer.

Both the rubber layer and the airbag layer are made of tire rubber, which is a relatively common material, can be made from recycled old tire rubber, has low cost, and can be used repeatedly.
