Abstract

A kind of three-level buffer unit when colliding the present invention relates to alleviation automobile, is made of rubber layer, air bag layer, spring layer, it may be mounted at automobile and is easy to issue licence the position of collision, such as the lateral location of headstock, the tailstock and vehicle.Done from the right side is rubber layer, air bag layer, spring layer successively to the left, the gentle cystoblast of rubber layer is sticked together by viscosity connection, together with air bag layer is bolted to connection with spring layer, spring layer is then bolted on the easy position that collides such as headstock, the tailstock or car door, air bag layer is set there are two pressure limiting hole, and it is controlled by pressure limiting opener herein, when the pressure in air bag layer reaches preset predetermined value, limiting mechanism of pressure is opened, gas in air bag enters pressure limiting hole by the stomata of limiting mechanism of pressure both sides, and is discharged by the gas vent of spring layer both sides.The present invention can effectively dissolve the impact force generated in automobile collision procedure, reduce the degree of injury of vehicle, protect occupant safety, cheap, effectively practical.

Description

A kind of three-level buffer device for collision of automobile
Technical field
The invention belongs to motor vehicle passive security protection technology fields, especially knock into the back in vehicle, front and side A kind of buffer protection device of buffer protection function can be played when collision.
Background technology
With being continuously increased for car ownership, road is more and more crowded, and road conditions also become increasingly complex, and traffic accident is frequent Occur, various collision accidents are commonplace, and the passive security performance of automobile becomes more and more important.Existing vehicle passive safety is anti- Shield includes mainly safety belt, air bag, bumper etc., but the protective effect that these devices play in actual accidents is very It is limited.At present the passive security safeguard procedures majority of vehicle is to absorb impact force by damaging automobile predecessor, is reduced with this Personnel injure.Therefore, problem of the existing technology is:To ensure driver and passenger's safety, when vehicle collides, vehicle damage Seriously.
Invention content
The present invention can effectively dissolve the impact force generated in automobile collision procedure, reduce the degree of injury of vehicle, protect Occupant safety is protected, it is cheap, it is effectively practical.
The technical solution adopted by the present invention to solve the technical problems is:A kind of three-level buffer device for collision of automobile, it can With mounted on the position that automobile is easy to collide, such as the lateral location of headstock, the tailstock and vehicle, from right to left successively by rubber Layer, air bag layer, spring layer three-level buffer unit composition, rubber layer are sticked together by viscosity connection and air bag, air bag layer and bullet Spring layer is fixed together by using bolt, and spring layer is then bolted on headstock, the tailstock or car door etc. and easily occurs Colliding part, air bag layer are set there are two pressure limiting hole, and are controlled by pressure limiting opener herein, when the pressure in air bag layer reaches When to preset predetermined value, limiting mechanism of pressure is opened, and the gas in air bag enters pressure limiting hole by the stomata of limiting mechanism of pressure both sides, is arranged It is discharged into spring layer, and by the gas vent of spring layer both sides, the thickness of the rubber layer is 30~50mm.
Pressure limiting opener at the air bag layer pressure limiting hole is made of pressure release spring and pressure relief plug, the pressure relief plug Pressure limiting hole is blocked, pressure release spring is in pressure relief plug posterior support pressure relief plug.
The air bag layer is equipped with charge valve.
16 springs are arranged in the spring layer altogether, are fixedly connected together by the gentle cystoblast of bolt, in spring layer both sides Equipped with gas vent.
The gentle cystoblast of the rubber layer is made by rubber for tire, and material is relatively conventional, recyclable old tire rubber It makes, it is at low cost, it repeated multiple times can use.
Description of the drawings
Fig. 1 is a kind of three-level buffer unit structure schematic diagram alleviated when automobile collides of the present invention.
1- rubber layers in figure, 2- air bag layers, 21 and 22- pressure limitings hole, 3- spring layers, 31 and 32 gas vents, 4- pressure limitings are opened Mechanism, 41- pressure limiting plugs, 42- pressure limiting springs, 5- charge valves.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
Referring to Fig. 1, the present invention is a kind of three-level buffer unit of alleviation automobile when colliding, by rubber layer, air bag layer, Spring layer is constituted, it may be mounted at the position that automobile is easy to collide, such as the lateral location of headstock, the tailstock and vehicle.From the right side It is rubber layer, air bag layer, spring layer successively to the left to do, and the gentle cystoblast of rubber layer is sticked together by viscosity connection, air bag layer and Spring layer is bolted to connection together, and spring layer is then bolted on headstock, the tailstock or car door etc. and easily touches Hit position, air bag layer sets that there are two pressure limiting holes, and is controlled by pressure limiting opener herein, when the pressure in air bag layer reaches When preset predetermined value, pressure relief plug is jacked up, and pressure release spring is compressed, i.e., limiting mechanism of pressure is opened, and the gas in air bag is by limit The stomata of press mechanism both sides enters pressure limiting hole, discharges into spring layer, and be discharged by the gas vent of spring layer both sides.
The thickness of the rubber layer is 30~50mm.
Pressure limiting opener at the air bag layer pressure limiting hole is made of pressure release spring and pressure relief plug, and air bag layer, which is equipped with, to be filled Air valve.
The pressure relief plug blocks pressure limiting hole, and pressure release spring is in pressure relief plug posterior support pressure relief plug.
16 springs are arranged in the spring layer altogether, are fixedly connected together by the gentle cystoblast of bolt, in spring layer both sides Equipped with gas vent.
The gentle cystoblast of the rubber layer is made by rubber for tire, and material is relatively conventional, recyclable old tire rubber It makes, it is at low cost, it repeated multiple times can use.
