Abstract
The utility model discloses a vehicle collision preventing device, and aims to provide a collision preventing device which can protect passengers and vehicles. The utility model is composed of two two-stage oil buffers and two sets of air sacs, wherein the two-stage oil buffers can efficiently absorb the collision energy gradually during collision to protect passengers and vehicles. When the collision strength exceeds a definite value, the air sacs can provide auxiliary protection to absorb residual energy, so the protection is reliable and thorough. The utility model is suitable for various motor vehicles. Compared with the prior art, the vehicle collision preventing device has the advantages of favorable protective effect, wide protective range and repeated use.
Description
Technical field
The utility model relates to a kind of anti-collision device for automobile that is used for the automobile protection.
Background technology
At present in auto against protection safety method index; only pay attention to protection occupant's safety; when allowing collision happens in design; make the body forward structure gross distortion to absorb impact energy as far as possible; be aided with the air bag in the operator's compartment again; safety strap makes the occupant avoid being subjected to grievous injury, and the vehicle after the collision is well damage even scrap then, has caused serious property damage.The anterior safety lever of installing of some overland vehicles and truck can only protect slight scratching and collide, and can not effectively protect vehicle.
Summary of the invention
The utility model proposes a kind of oil gas combined type automobile anticollision device, purpose is that when automobile bumps this beam can effectively absorb impact energy, thereby realizes not only to the occupant but also to effective protection of vehicle.The beam that the utility model proposes is to be constituted jointly by oleo gear and air bag, at front part of vehicle 6 two two-stage oleo gears 2,3 are installed, the oil pressure damper that the oleo gear similar is common, the cylinder body 2 of first order energy disperser also is the piston rod of second stage energy disperser 3, erection insurance thick stick 1 on the piston rod 7 of first order energy disperser, at front portion of car body air bag 4 and high-pressure gas bottle 5 are housed also, simultaneously the frizzen of chewing in order to shake-up high-pressure gas bottle gas in the installing of the inboard of bumper/spoiler 18.When automobile bumps; bumper/spoiler 1 is impacted; compressing piston rod 7 moves backward; fluid in the extruding cylinder body 2 is discharged by throttling sheet on the piston; absorbed a part of impact energy; when the top of cylinder body 2 is arrived in piston motion; cylinder body 2 advances in cylinder body 3 as the piston rod of second stage energy disperser; fluid in the extruding cylinder body 3 is discharged by the throttling sheet; absorbed a part of impact energy again; if impact strength is very big; when cylinder body 2 moves in cylinder body 3 when surpassing a certain setting value, the frizzen 8 that is arranged on bumper/spoiler 1 inboard will touch the gas of high-pressure gas bottle to be chewed, and moment makes airbag aeration; absorb remaining impact energy, thereby realize effective protection occupant and vehicle.The used oil compression buffer can make I and II oil cylinder recovery original state continue to use by force-extension.
It is effective that the existing relatively collision prevention of vehicle fender guard of the utility model has anticollision, and protection domain is wide, reusable advantage.
Description of drawings
