Abstract
The utility model relates to a protecting device for fending off direct blows from other vehicles or objects. The utility model is composed of a pressurization gas bag and a high-pressure gas generating device which are connected with each other, and the pressurization gas bag can be sufficiently expanded. The electrical contact of the high-pressure gas generating device is installed at the limit point of the brake, the inner part of a cavity body is provided with a plurality of combustion chambers, gunpowder and ignition elements are installed in the combustion chambers, and pressure reducing plates are installed at the mouth parts of the combustion chambers; so the gas cushion of high pressure can be formed in the front of the vehicle when the vehicle is braked on a crash basis, and the impact force can be moderated.
Description
The utility model relates to the shock absorber that a kind of automobile bumps because of sudden accident.
Automobile if obstacle appears suddenly in the place ahead, tends to have an accident as people's jaywalk or front vehicles sudden stop etc. are arranged suddenly in the process of moving, light damaged vehicle then, injury to personnel, heavy then car crash.Scene evidence obtaining according to traffic accident over the years, except the situation of car brake failure, chaufeur more than 8% brakes, but because situation is unexpected, the brake aftercarriage still slides forward under huge effect of inertia, and directly clash into obstacle, the impulsive force of moment has surpassed the bearing strength of automobile body and has caused casualties.
The purpose of this utility model is to provide a kind of automobile that makes at the file protect of haveing no alternative but to take place obtain cushioning under the situation of direct impact, moment before collision takes place, at the anterior formation of car high pressure gas bed course, slows down impulsive force.
The utility model connects high pressure gas generating means 3 by air bag 1 and constitutes, and the electric contact 9 of high pressure gas generating means 3 is installed in the brake limit point.
High pressure gas generating means 3 is made of cavity 4 and several piece decompression plate 5, cavity 4 has combustion chamber 7 on the end surfaces 4a of air bag 1, described combustion chamber 7 is blind holes, interior primer and igniter 8, igniter 8 is by wire connecting power and electric contact 9, described decompression plate 5 is plates that have many pores, and decompression plate 5 is installed in described end surfaces 4a place.
Being equipped with igniter 8, electric contact 9 bonded assembly power supplys can be to the continuous interval trigger circuit of igniting in batches of the igniter of each combustion chamber.
When the driver finds that the place ahead obstacle occurs suddenly under steam, carry out emergency brake immediately, the limit point of stepping on brakes, the electric contact of igniter is connected, gunpowder explosion in the combustion chamber, detonating gas its blast impulse power of orifice restriction effect of pore on the decompression plate obtains relaxing, among high pressure gas behind the multiple tracks decompression plate charge into the air bag that is in contraction state, form the high-pressure buffer air cushion, whole process only needs 0.1～0.2 second, and car body touches obstacle through the high pressure air cushion, its huge preshoot kinetic energy is progressively discharged, impulsive force is reduced to car, in the limit that the people can bear, if automobile is thrusted into, the people can be ejected by air cushion, can be not wounded or roll under the wheel, injures and deaths can not take place in the occupant on the car under the situation of fastening the safety belt, and car only can paint when bumping against with huge obstacle, the lampshade scratch, car body is injury-free.
The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to accompanying drawing
The utility model connects high pressure gas generating means 3 by air bag 1 and constitutes, the electric contact 9 of high pressure gas generating means 3 is installed in brake limit point 10, described air bag 1, high pressure gas generating means 3 are contained on the guard of automotive front end, bag material adopts high-intensity temperature resistant rubber and cord, compressive resistance need reach 25 kilograms of every sq cms, air bag is cylindrical when expansion state amounts to mode and umbrella is basic identical, sectional dimension is about 20cm * 25cm when fold line 2 folding is dialled the air bag contraction state, does not influence the attractive in appearance of vehicle and travels.Described high pressure gas generating means 3 is made of cavity 4 and several piece decompression plate 5, cavity 4 has many combustion chambers 7 on the end surfaces 4a of air bag 1, combustion chamber 7 is blind holes, interior primer and igniter 8, igniter 8 is by wire connecting power and electric contact 9, igniter 8 can be heating wire or high-pressure fire plug, and described decompression plate 5 is plates that have many pores 6, and polylith decompression plate separates a bit of distance and is installed in end surfaces 4a place abreast.With igniter 8, electric contact 9 bonded assembly power supplys are equipped with can be to the continuous interval trigger circuit of igniting in batches of the igniter of each combustion chamber, and to relax the explosive force of gunpowder, institute's interlude is extremely short.The explosive total amount of being put in each combustion chamber should be by calculating decision, the gas gross that blast is generated should make air bag reach the pressure of 8～15 kg/cm, 0.5～1 meter of air bag diameter, length equates with overall width, is example with the black powder, and volume ratio is about 1:1000 before and after its blast, can extrapolate gunpowder in view of the above uses the total amount chaufeur when emergency brake, the brake limit position of stepping on, electricity touches 9 conductings, the time igniting that each combustion chamber is extremely short at interval in batches.The high pressure gas that blast produces slow down impulsive force through the orifice restriction effect of decompression plate 5, even the gas flaring that is in the contraction state of existing side by side becomes cylindrical high pressure air cushion.
