Automobile collision active braking and fuel cutting-off system

Technical field

The utility model relates to a kind of automotive fittings, particularly a kind of auto-safety mechanism.

Background technology

Federal bumper is the safety device that absorbs the foreign impacts power that relaxes, protection vehicle body front and rear part.Before 20 years, bumper/spoiler is based on metallic material before and after the car, is that steel plate more than 3 millimeters strikes out the U-lag steel with thickness, surface treatment chromium plating, with chassis side rail riveted joint or weld together, with vehicle body one section bigger gap is arranged, seem parts that add up.

Along with developing of automobile industry, Federal bumper has also moved towards on the road of innovation as a kind of important safety device.Bumper/spoiler is except keeping original defencive function before and after the car of today, also will pursue harmony and unification with the car body moulding, the lightweight of pursuit itself.In order to reach this purpose, the front and back bumper/spoiler of car has adopted plastics at present, and people are called the plastics bumper/spoiler.

The plastics bumper/spoiler is made up of outside plate, padded coaming and crossbeam three parts.Wherein outside plate and buffering material are made of plastic, and crossbeam thickness is that the cold-rolling thin plate of 1.5 millimeter is stamped to form U-lag; Outside plate and buffering material are attached on the crossbeam, and crossbeam is connected with the chassis side rail screw, can disassemble at any time.The plastics that this plastics bumper/spoiler uses use polyester system and polypropylene-based two kinds of materials substantially, adopt injection moulding to make.The bumper/spoiler of for example beautiful 405 cars has adopted the polyester based material also to make with reaction injection mold forming method.And the bumper/spoiler of the model cars such as Xiali of the Santana in popular Audi 100, golf, Shanghai, Tianjin has adopted polypropylene-based material to make with injection moulding.Also have a kind of plastics that poly-carbon ester is that are called abroad, infilter alloying component, adopt the injection molding method of alloy, the bumper/spoiler that processes not only has high-intensity rigidity, also have the advantage that can weld, and coating performance is good, the consumption on car is more and more.

The plastics bumper/spoiler has intensity, rigidity and ornamental, on safety, can play buffer action when automobile crashes, car body before and after the protection; From in appearance, can be very natural be combined in one with car body, completely be integral, have excellent decoration, become the vitals of decorating the car external form.

Statistics is the traffic accident of several years generation in the past, and we find that most traffic accident is because carelessness and wrong people in principle on driver's consciousness cause; It is not high to add the safety performance of vehicle own, thereby makes people's lives and properties be subjected to great harm.

2002, when Mrs Baoding drives Audi's A6 car and walks to a dwelling district, the child owing to scurry out suddenly in the place ahead, this Ms is because alarmed, mistake is stepped on throttle as brake, cause Audi car one tunnel to push way by shoving or bumping, and then and there five people is collided to death, the people is injured more than ten, and the vehicle damage is serious.

2003, on the fourth ring road in Beijing, a Jetta chauffeur finds that the pedestrian appears suddenly in the place ahead, but because the speed of a motor vehicle is too fast, people's response lag and action lag behind in addition, and in the collision process because the vehicle strenuous vibration is cast the driver aside driver's seat (be equivalent to vehicle and do not take any braking action), major traffic accidents have directly been caused, car crash.

As can be seen, the people is in passive status all the time in vehicle generation traffic accident process from top case incident, and people's active tasks is the behavior of constraint self before traffic accident takes place, the generation that avoids traffic accident; But in the process that traffic accident takes place; because people's consciousness and the restriction that reflection is subjected to physiological condition; can not take place moment in accident make the operation that accurately puts in place flexibly rapidly; so we should constantly improve the safety performance of vehicle self, protect the safety of people's lives and properties on one's own initiative.

Federal bumper can only protect automobile to alleviate bump; object of protection is the occupant; then do not play protective action for car outside personnel; under the panic-stricken situation of driver; be necessary to take a kind of technology that the situation that automobile pushes one's way by shoving or bumping, thrustes into is continuously minimized, to protect people's life and public property safety to greatest extent.

Summary of the invention
