Abstract
The invention provides a protective air bag in a bumper of a locomotive car, which aims to solve the problem that the existing air bag in a car does not play a role in protecting the cars and passengers crashed by the cars in car crash. The protective air bag has the key points as follows: a main air bag, an auxiliary air bag and an arm protecting air bag are arranged between the locomotive car bumper and the car body; after the power supply of gas generators is switched on by a driver, two gas generators are used for inflating the main air bag, the auxiliary air bag and the arm protecting air bag respectively, the main air bag, the auxiliary air bag and the arm protecting air bag rush out an air bag bin one after another, so that air bag protection is formed at the front side and the rear side of the locomotive car. thus rigid crash of the original cars is changed into flexible crash, and the sufferers and cars can be protected.
Description
Technical field
The present invention relates to a kind of protection air bag of self-propelled vehicle, be arranged on the protection air bag in the bumper for automotive vehicle specifically.
Background technology
In roadlice, be provided with the protection air bag at present, specifically be,, protection is provided being sitting in front-seat driver and conductor in that a protection air bag is set respectively in the bearing circle of low and middle-grade roadlices and in the right-hand member of operator's station; On high-grade roadlice, in the back of front-seat each back of seat, set up a protection air bag again, for the personnel that ride in back row provide protection.This set has significant effect at the protection air bag of automotive interior for the injures and deaths degree that alleviates the driver and conductor.But this protection air bag does not play any protective effect to the vehicle in when collision, to vehicle collision to the pedestrian do not play any protective effect yet, this is a big defective of built-in protection air bag.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of protection air bag that is arranged in the bumper for automotive vehicle.
The objective of the invention is to realize like this: the air bag storehouse is set between bumper for automotive vehicle and car body, on the surface of bumper/spoiler the air bag door is set, the lower edge and the bumper/spoiler of this door are hinged; Order according to the innner and outer behind the major and minor airbag fold of unaerated is placed in the air bag storehouse, and the top of main gasbag and the bottom of balloonet link together;
In the position of former protection crossbeam (need unload the place where troops were originally stationed of getting off and protect crossbeam) major and minor two mixed type twin-stage gas generators (to call gas generator in the following text) are installed on the crossbeam of the left and right sides; Be respectively major and minor air bag air feed, wherein the inlet end of balloonet and armlet air bag and being connected on the secondary gas generator outlet side; Between main gasbag and main gas generator, be provided with and eject ballonet; Main gasbag with eject ballonet and be connected by the truncated cone-shaped gas line; The larger diameter end of truncated cone-shaped gas line is facing to main gasbag; The truncated cone-shaped vent plug is set on the truncated cone-shaped gas line, and the inlet end that ejects ballonet is connected on the main gas generator outlet side; After major and minor airbag aeration ejects; Main gasbag is horizontal stripe shape and protects the front at bumper/spoiler; The main body of balloonet is spill on main gasbag, between two columns of balloonet, several protective ropes is set, position that the protection bumper for automotive vehicle is above and the above position of pedestrian's upper body; Connect respectively at the front end of two columns and to be the armlet air bag that connects arc, two armlet air bags after the inflation surround semicircle;
The current supply circuit of gas generator is connected on the power supply after by following three branch road parallel connections, and source switch K is arranged on the driver and stretches out one's hand the place that can run into, and these three branch roads are: main gas generator is connected with time relay; Secondary gas generator; Vibration sensor is connected with electromagnetic valve.Electromagnetic valve is arranged on the inlet end of armlet air bag, is normal off status; Vibration sensor is arranged on bumper/spoiler or the air bag.
Working process is: door is closed at ordinary times, and above-mentioned three air bags are placed in the air bag storehouse.When self-propelled vehicle was about to bump, the driver opened K switch, secondary gas generator at first electric, the first order gas of its generation is balloonet inflation, the balloonet that expands gradually backs down door and delivers from godown gradually; Then second stage gas produces, and balloonet delivers from godown fully and is full of gas, takes main gasbag simultaneously out of and delivers from godown; Simultaneously time relay is closed, connects the current supply circuit of main gas generator, and main gas generator gets electric, and the first order gas of its generation is input to earlier and ejects ballonet, ejects after ballonet expands, and main gasbag is ejected the air bag storehouse gradually; Then, main gas generator produces second stage gas, and air pressure increases, and backs down the truncated cone-shaped vent plug, and the truncated cone-shaped gas line is unimpeded, for main gasbag is full of gas.The main gasbag that delivers from godown fully is horizontal in the front of bumper/spoiler, and balloonet that delivers from godown fully and protective rope protect above position of bumper for automotive vehicle and the above position of pedestrian's upper body on main gasbag.After vehicle collision was vibrated to the pedestrian, vibration sensor began action, connected the solenoid valve loop; Electromagnetic valve is opened, and secondary gas generator is the armlet airbag aeration, and armlet air bag semicircular in shape is launched; To be hit pedestrian's circle in the middle of armlet air bag and major-minor air bag; To be hit the pedestrian and embraced, and prevent to eject, and avoid being hit pedestrian's body and receive the secondary injury.
Compared with prior art, the invention has the beneficial effects as follows: it is started with from the protection car body, for after car body is provided with safety air bag; Through the protection car body, the quilt that protect the rider, clashes with car is thrusted into, and its security concepts is advanced more; After all cars are all installed the present invention, bump against the flexibility that becomes two car air bags by two original rigidity of vehicle body and bump against the impact that so not only can alleviate car greatly; The more important thing is also to alleviate injury greatly, also reduced the accident cost simultaneously the rider.
