Abstract

The utility model relates to an active external auxiliary protection safety air bag device for a vehicle carriage. The utility model is characterized in that air bag components outside the carriage are fixed in bag outlet holes (8) and (9) on the front edge and the rear edge outside the vehicle carriage; the air bag components are connected with an electronic control IC (3) and can be inflated immediately to form an air cushion before the automobile are crashed. The utility model can form a layer of air cushion after a vehicle is crashed by other vehicles or obstructions are crashed by the vehicle to furthest absorb energy of primary collision to furthest protect safety of passengers in the vehicle carriage.

Description

Auxiliary protection safety airbag apparatus outside the active compartment

The utility model relates to the anticollision device of power actuated vehicle, particularly in the safety device of automobile collision preventing.

At present, running car is mainly by driver's operation, once when meeting accident often chaufeur also do not react and knocked car in front or obstacle, perhaps the car of oneself is hit by the car of back.After this primary collision takes place, the car speed steep variation, chaufeur and occupant can be subjected to the effect of force of inertia and travel forward, and bump with bearing circle, Windshield and instrument desk etc. in the car, and this secondary collision just causes personnel's injures and deaths.For the injury that alleviates or avoid secondary collision that the people is caused, near inflatable air bag rapidly when having begun in the existing automobile to be equipped with car collision the control wheel in the compartment, air bag just places to play between chaufeur and the bearing circle and slows down the impulsive force of people to things such as bearing circle, reaches the purpose of the injury that alleviates personnel.But have a lot of scenes of the accident to prove, when automobile generation sharp impacts, car front portion or rear portion are hit presses and gross distortion, and still the life security of personnel in the compartment in serious threat.

The purpose of this utility model provides auxiliary protection safety airbag apparatus outside a kind of active compartment that hits pressure can alleviate automobile and automobile, automobile and obstacle and bump against the time; can before collision, between vehicle body and Ta Che or obstacle, form one deck air cushion; absorb the energy of primary collision as far as possible, protect the safety of occupant in the compartment to greatest extent.

Technical solution of the present utility model is on the basis of existing relative distance speed sensor, speed sensor, electron steering IC, the utility model particularly the bag hole internal fixation that goes out on the forward position outside the automobile railway carriage or compartment and edge, back to have what be connected with electron steering IC can be to inflate air bag component outside the formation air-sprung railway carriage or compartment automobile bumps before at once.

The above electron steering IC communicates with power supply, and links to each other with warning indicator lamp.

Air bag component includes a casing outside the railway carriage or compartment of the present utility model, and the casing internal fixation has a firing unit and an aerating agent reservoir, on the side that goes out bag hole on the automobile of casing a hole is arranged, and the aperture internal fixation has air bag.

More than fine pore is arranged on the air bag of the present utility model.

Principle of work of the present utility model is in the automobile sport, the relative distance speed sensor constantly detects the some rice of vehicle front and rear clear and relative distance and relative velocity, the speed sensor data are to be provided by speed gauge, are sent to the data model that has solidified on electron steering IC and the IC in the relative distance velocity amplitude data of the automobile that constantly detects self velocity amplitude and car and car and compare.When the relative velocity of front car and rear car increases to suddenly greater than a certain threshold value, relative distance reduces suddenly and less than a certain safety distance, self speed is during again greater than threshold value, promptly reach critically limit, electron steering IC makes the logic determines that is about to bump, and operating point fire program immediately, fire lighter outside the railway carriage or compartment in the air bag component is detonated, the aerating agent decomposes produces rapidly the full air bag of a large amount of gases, air bag go out simultaneously before the automobile and after the edge go out the capsule that the outside rapid expansion of bag hole becomes definite shape.The air bag that has been full of gas or forms one deck air cushion between car and the obstacle between car and car, when automobile bumps, and fine pore outwards exhaust under pressure on the air bag, air bag has absorbed the portion of energy of collision.

The utility model has the advantages that and before car and car or car and obstacle collision, to have formed one deck air cushion between them, absorb the energy of primary collision as far as possible, protect the safety of occupant in the compartment to greatest extent.

Below in conjunction with accompanying drawing embodiment of the present utility model is described:

Bump gas in the rear gasbag of Fig. 7 the utility model automobile is discharged the view of rear gasbag by its micropore.

Shown in Fig. 1,2,3,4,5,6,7, the utility model on the basis of the relative distance speed sensor 1 of prior art, speed sensor 2, electron steering IOSRS IC3, outside the automobile railway carriage or compartment forward position and edge, back go out bag hole 8 and 9 internal fixation have air bag component outside the railway carriage or compartment that is connected with IOSRS IC3.IOSRS IC3 communicates with power supply, and links to each other with warning indicator lamp.Air bag component has a casing 4 outside the railway carriage or compartment, casing 4 internal fixation have a fire lighter chamber 5 and an aerating agent reservoir 6, on the side that goes out bag hole on the automobile of casing a hole is arranged, the aperture is fixed with the air bag 7 of folding unaerated, and fine pore is arranged on the air bag 7.

Shown in Figure 2, the utility model is the fixing relative distance speed sensor in forward position outside the compartment, and has two to go out bag hole 8.

Shown in Figure 3, the utility model is the fixing relative distance speed sensor in edge, back outside the compartment, and has two to go out bag hole 9.

Shown in Figure 4, the state before the car collision during airbag aeration;
