Abstract
The utility model relates to a car safety traveling protection device, in particular to a car collision cushioning device, and solves the problem that the rigidity collision is not reduced effectively while the car collision occurs in the prior art. The car collision cushioning device comprises a guide sleeve fixed on the inner side of the transverse and the longitudinal beam of the chassis frame, a screw rod with one end inserted into the guide sleeve and fixed by a nut, an active bumper fixed on the other end of the screw rod and an elastic cushioning mat sleeved on the screw rod and positioned between the active bumper and the transverse and the longitudinal beam of the chassis frame. Compared with the prior art, the utility model changes the former bumper rigidly connected with the chassis frame into the active elastic bumper, changes the rigid collision into the elastic collision, reduces the impact force suffered by the passenger inside the car, and protects the only one time invaluable life of the people inside the car.
Description
Technical field
The utility model relates to a kind of device that ensures that automotive safety is exercised, and is specially a kind of automatic buffer crash device.
Background technology
Present automobile pollution sharply increases, and traffic accident takes place frequently, particularly because the speed of a motor vehicle is too fast, and chaufeur is out of control, and mechanical breakdown, brake failure, multiple reason such as sleety weather causes vehicle to bump mutually, produces serious consequence.That uses on the cars on hand generally can alleviate collision and bring the device of loss, basic is the interior air bag of car and the bumper/spoiler in car the place ahead etc., but existing bumper/spoiler all is to rigidly fix to be connected with chassis frame, therefore find in actual the use, use this class device (fixing bumper/spoiler particularly is rigidly connected) can not effectively slow down the impulsive force that the collision back produces on the automobile.
Summary of the invention
The utility model can not effectively to alleviate the problem of rigid shock when existing automobile to bump in the prior art in order solving and a kind of automatic buffer crash device to be provided.
The utility model is realized by following technical scheme: the automatic buffer crash device, comprise the pilot sleeve that is fixed in chassis frame horizontal stroke, longeron inboard, one end penetrates pilot sleeve and nutted screw rod, is fixed in the active bumpers of the screw rod other end and is placed on the screw rod and the elastic buffering pad between active bumpers and chassis frame horizontal stroke, longeron.During actual the use, this damp impacts device can be fixed on front cross rail, after cross member or the longeron of vehicle frame, in case the front portion of car, rear portion or left and right sides and vehicle or other object bump, active bumpers is contacted with the object that is collided, the energy that produces can be cushioned pad and absorb, thus the safety of human body in the service truck.Screw rod can guarantee being connected and unidirectional moving between active bumpers and chassis frame, the cushion rubber.
This automatic buffer crash device also comprises the pressurized air assistant cylinder that is fixed on the longitudinal and transverse beam of chassis frame, is provided with piston in the assistant cylinder, and the end and the active bumpers of piston rod are connected and fixed.When active bumpers and vehicle or other objects bump, active bumpers promotes piston and moves, and the air in the compression assistant cylinder produces elastic force when air compresses rapidly, rigid collision is changed into bumping collision, thus the energy that further damp impacts produces.About 100,000,000 of the existing automobile pollution of China, about 1,000,000,000 of world car recoverable amount, and be ascendant trend year by year, along with the progress of science and technology, the increasing sharply of expressway, the speed of a motor vehicle of automobile is also accelerated gradually, the speed of a motor vehicle that has surpasses 300KM/H, and this has increased the incidence of accident undoubtedly.Add up according to incomplete data, the traffic accident that China took place in 2004 is 517889, wherein death toll is 107779 people, hinder people more than 250,000, the traffic accident incidence is first of the world, and the trend of increasing arranged, direct economic loss reaches 9.6 hundred million yuan, indirect economic loss is just higher, and whole world every day is because the dead people more than 3,000 of traffic accident, annual 1200000 people, wounded or disabled 3,500 ten thousand people, the Asian-Pacific area has more than 40 ten thousand people to be killed in an automobile accident every year, and the disabled reaches millions of, exceeds 10～50 times than developed country.The utility model is that the car body of automobile adds that together " safety strap " this device is widely used, and enormous amount has wide prospect, and will produce hundreds of millions of economic benefits and social benefit.Its appearance will be an invention on the vehicle operational safety history.Compared with prior art; this device has become mobilizable elastic bumper with original with the rigidly connected bumper/spoiler of chassis frame; make rigid collision become bumping collision, alleviated the impulsive force that the occupant is subjected to, thereby protected occupant's one-shot valuable life.

The specific embodiment
A kind of automatic buffer crash device, comprise the pilot sleeve 1 that is fixed in chassis frame horizontal stroke, longeron 6,7 inboards, one end penetrates pilot sleeve and with the fixing screw rod 3 of nut 2, is fixed in the active bumpers 4 of the screw rod other end and is placed on the screw rod and the elastic buffering pad 5 between active bumpers and chassis frame horizontal stroke, longeron.Also comprise the pressurized air assistant cylinder 8 that is fixed on the longitudinal and transverse beam 7,6 of chassis frame, be provided with piston 9 in the pressurized air assistant cylinder, the end and the active bumpers of piston rod 10 are connected and fixed.In order to make stress balance, each active bumpers can dispose two pressurized air assistant cylinders and at least two group pilot sleeve and screw combinations at least during concrete enforcement.As schematically shown in Figure 2, piston rod 10 is connected with active bumpers 4 by screw 11.Assistant cylinder and piston can be made by aluminum alloy, copper alloy or iron and steel (need add antirust chromium plating handle) or polyethylene and polypropylene composite material.In store air, and need dustproof and waterproof sealing.Elastic buffering pad can be made by poly-chloroprene rubber, butaprene, buna-S elastomeric material.Look the pressurized air assistant cylinder that the vehicle size is installed different size at existing car chassis vehicle frame groove,, active bumpers and cushion rubber are installed simultaneously at distance chassis frame horizontal stroke, longeron 150-200 millimeter place.
