Description

The external safety air bag of automobile

Technical field

The utility model relates to a kind of air bag, relates to the external safety air bag of a kind of automobile specifically.

Background technology

Along with expanding economy, the owning amount of automobile is more and more, and when the increase of automobile quantity can be convenient for people to go on a journey, the quantity of traffic accident was also in rising trend.Present employed automobile, erection insurance thick stick before and after automobile if fender bender takes place, all is the rigidity bump mostly, causes the damage of personal injury and vehicle easily.To the injury of chaufeur, a lot of cars are installed air bag in operator's compartment the place ahead when bumping against in order to reduce vehicle, and after bumping, safety air bag is opened, and can reduce chaufeur and strike on the rigidity car body, reduces the injury to chaufeur.But owing under a lot of situation, when traffic accident takes place, be difficult in time open air bag, so the air bag in the operator's compartment is difficult to reach its intended purposes.

Summary of the invention

For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of automobile external safety air bag, this external safety air bag simple installation, not influencing automobile normally uses, simple in structure, result of use is good, can effectively improve the safety performance of automobile, reduces personal casualty and economic loss that traffic accident causes.

The technical scheme that its technical matters that solves the utility model adopts is:

The external safety air bag of a kind of automobile, its structural feature is: the headstock and the tailstock at automobile are installed air bag respectively, and the gas port of air bag connects gas cylinder, holds NaN in the said gas cylinder ₃Solid, on the said gas cylinder light-up plug is installed, light-up plug connects the automatic switch by central process unit control, the main supply switch of said central process unit places other source switch places in the car, on headstock, the tailstock, install and be used for the relative velocity of probe vehicles and obstacle and the infrared detector of distance, this detector connects said central process unit, install and central process unit bonded assembly telltale and annunciator at the car surface place, installs and central process unit bonded assembly hand switch on vehicle steering.

The beneficial effects of the utility model are that principle of work of the present utility model is: filling NaN in the air bag ₃Solid, under the effect of electro spark, 2NaN ₃=2Na+3N ₂, gas is opened air bag rapidly, because gas plays buffer action, impulse force reduced when high-pressure gasbag bumped against automobile and object.The utility model is not installed air bag at headstock, tail part, and two gas ports of air bag are connected with gas cylinder respectively, and obturage, and set up light-up plug on the gas cylinder, hold NaN in the gas cylinder ₃Solid, light-up plug is connected with automatic switch, automatic switch is controlled by central process unit, central process unit is differentiated and processing data, the main supply switch of central process unit places other source switch places in the car, simultaneously on headstock, the tailstock, pacify infrared detector, be used for the relative velocity and the distance of probe vehicles and obstacle, detector is connected with central process unit, the gained data are handled by central process unit, set up telltale and annunciator in the car surface, set up hand switch on bearing circle, all be connected, obtain to such an extent that data will show on telltale with central process unit.The utility model is provided with service conditions: when having only the speed of a motor vehicle greater than 50 kilometers/hour, air bag just can be opened; Have only relative distance to acquire a certain degree, promptly brake and turn to when all having little time air bag just can open.Concrete working data is: 1. the speed of a motor vehicle is opened air bag in the 50-60 kilometres per hour at distance obstacle 1.0-1.5 rice; 2. the speed of a motor vehicle is opened air bag in the 60-70 kilometres per hour at distance obstacle 1.5-2.0 rice; 3. the speed of a motor vehicle is at 70-80 kilometer/hour, at distance obstacle 2.0-2.5 rice airbag-releasing; 4. the speed of a motor vehicle is at 80-90 kilometer/hour, at distance obstacle 2.5-3.0 rice airbag-releasing; 5. the speed of a motor vehicle is at 90-95 kilometer/hour, at distance obstacle 3.0-3.5 rice airbag-releasing; 6. the speed of a motor vehicle is at 95-100 kilometer/hour, at distance obstacle 3.5-4.0 rice airbag-releasing; 7. the speed of a motor vehicle is at 100-10 kilometer/hour, at distance obstacle 4.0-4.5 rice airbag-releasing; 8. the speed of a motor vehicle is at 105-110 kilometer/hour, at distance obstacle 4.5-5.0 rice airbag-releasing; 9. the speed of a motor vehicle is at 110-115 kilometer/hour, at distance obstacle 5.0-6.0 rice airbag-releasing; 10. the speed of a motor vehicle is at 115-120 kilometer/hour, at distance obstacle 6.0-7.0 rice airbag-releasing; 1 kilometer/hour of each later on increase, opening distance increases by 0.2 meter.Job procedure of the present utility model: hand switch is only in the speed of a motor vehicle during greater than 50 kilometers/hour, could use, when the speed of a motor vehicle reaches 50 kilometers/hour, central process unit uses automatic switch to be in the preparation starting state, in the speed of regulation, when the spacing obstacle starts 2 times of distance for regulation, central process unit makes the alarm equipment alarm prompting, the driver is regulated: when the speed of a motor vehicle and spacing all reach specified value, central process unit makes the automatic switch closure, form close circuit, light-up plug is emitted electro spark, NaN ₃Meet electro spark and decompose grand amount N ₂Thereby, make air bag in instantaneous expansion; When the speed of a motor vehicle during greater than 50 kilometers/hour, central process unit is received hand switch and is opened the back and regulate automatic switch at once and open, so that allow airbag-releasing.Requirement to air bag: the selected material of air bag must be high temperature resistant, high pressure, air bag can not broken because of impact, size must may be clashed into front or back to such an extent that the position is all blocked during airbag-releasing, the about 40-50 of thickness centimetre, internal pressure should be 4.5 barometric pressures during aerification, air bag must be thin slightly at the place, two side, in order to avoid balloon rupture and air-flow produces impulse force to Windshield, because outer air bag must exist, so some adjustment should be done in the position of interior airbag actuation condition and switch, because of particular case is decided, air bag can repeated usage.The utility model can be used on the luxury car, on some trucks.The utility model can make vehicle after bumping the dress accident, absorbs the impulsive force that automobile produces by air bag when bumping dress, can stop or reduce the harm of traffic accident effectively, and human body is hurt and the ruined degree of automobile thereby can reduce.The utility model simple installation does not influence automobile and normally uses, and simple in structure, result of use is good.
