Abstract
The invention discloses an automobile front collision safety protection unit, comprising an automobile engine chamber and a bumper arranged in front of the engine chamber. A gasbag is arranged in the bumper. The engine chamber is provided with an air duct, the front end of which is connected with an air inlet while the back end is communicated with two expansion pipes respectively arranged at both sides of the engine chamber. A shooting transducer and a receiving transducer are respectively arranged at the front end of the two expansion pipes. The receiving transducer is connected with the sensor and the microprocessor in sequence and the microprocessor is connected with the air generating device arranged inside the gasbag. The automobile front collision safety protection unit has the advantages of reasonable design, simple structure and reliable performance. When collision happens during high-speed driving, the collision force can be effectively relieved to prevent accident of damage of both car and the driver from happening.
Description
Technical field
The present invention relates to a kind of auto-safety mechanism, particularly a kind of safety device and safeguard for front run impact of vehicle.
Background technology
Be used for automobile at present, especially the safety precaution facility of C-class generally adopts the safety air bag that is installed in the car.Different according to the vehicle of car and class, set air bag quantity is not quite similar.Above-mentioned air bag can have been brought into play certain positive role when collision happens, can reduce the impact of car body to human body, driver and conductor's injures and deaths in the minimizing accident, but this safety air bag also has some shortcomings in actual use.The one, airbag-releasing is later opportunity, has only vehicle that bump back device takes place and just moves, and makes airbag-releasing, has incured loss through delay optimized protection opportunity, and air bag does not give full play of due protective effect; The 2nd, air bag is arranged in the car, therefore when bumping to car body without any protective effect.
Summary of the invention
The objective of the invention is the deficiency that exists at prior art, a kind of safety device and safeguard for front run impact of vehicle of reasonable in design, simple in structure, reliable working performance is provided.
Technical scheme of the present invention is: a kind of safety device and safeguard for front run impact of vehicle; the machinery space and the bumper/spoiler that is arranged on machinery space the place ahead that comprise automobile; be provided with air bag in the bumper/spoiler; it is characterized in that: be positioned at machinery space and be provided with airduct; the front end of described airduct connects ventilation inlet; its rear end is communicated with two telescopic pipes that are separately positioned on both sides in the machinery space; the front end that is positioned at two telescopic pipes is separately installed with transmitting probe and receiving transducer; receiving transducer connects sensor and microprocessor successively, and the microprocessor gas generating unit interior with being arranged on air bag is connected.
The present invention compared with prior art has the following advantages: the present invention is reasonable in design; simple in structure; reliable working performance; when in galloping, bumping; add the air bag that has been arranged at present in the car; then can play double protection, can alleviate collision dynamics effectively, reduce or prevent the accident generation of car crash human body and vehicle to the occupant.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of telescopic pipe 6 of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes the machinery space 1 and the bumper/spoiler 2 that is arranged on machinery space 1 the place ahead of automobile, be provided with air bag 3 in the bumper/spoiler 2; Be positioned at machinery space 1 and be provided with airduct 5, the front end of described airduct 5 connects ventilation inlet 4, its rear end is communicated with two telescopic pipes 6 that are separately positioned on both sides in the machinery space 1, the front end that is positioned at two telescopic pipes 6 is separately installed with transmitting probe 7 and receiving transducer 8, receiving transducer 8 connects sensor 9 and microprocessor 16 successively, and microprocessor 16 is connected with gas generating unit 10 in being arranged on air bag 3.
Described ventilation inlet 4 is arranged in the machinery space 1, or is arranged on the hatchcover of machinery space 1.
Described transmitting probe 7 and receiving transducer 8 are respectively light wave emitter and light wave receiver.
Described telescopic pipe 6 also be connected be arranged on air bag 3 in the piezo ceramic element 11 that is electrically connected of gas generating unit 10.
For ease of regulating the relation between the intake and the speed of a motor vehicle, describedly advance ventilation inlet 4 and be provided with the air door 12 that is used to regulate intake.
As shown in Figure 2, described telescopic pipe 6 is made up of the different sleeve pipe 15 of more piece caliber socket successively, is provided with retracing spring 13 and sealing member 14 between described sleeve pipe.
The principle of work of apparatus of the present invention is as follows:
Along with the startup of automobile and the apparatus of the present invention of travelling are started working, the wind that head-on blows enters the tube chamber of telescopic pipe 6 by ventilation inlet 4, airduct 5.Raising along with car speed, described intraluminal blast increases, constantly the blast that increases overcomes the resistance of retracing spring 13 gradually, and sleeve pipe 15 is pushed ahead successively, the front end face that causes the transmitting probe 7 that is arranged on telescopic pipe 6 front ends and receiving transducer 8 to stretch out headstock.At this moment, Ben Cheruo and front vehicles or object bump, no matter be by blocking the light wave between transmitting probe 7 and the receiving transducer 8, or the direct transmission of pressure by the telescopic pipe 6 that is impacted, the capital is by sensor 9 and microprocessor 16 or pass through piezo ceramic element 11, moment starts gas generating unit 10 work, make air bag 3 inflation and by ejecting in the bumper/spoiler 2, between two car bodies that are about to bump, form the elasticity barrier, thereby reduce the bump dynamics, alleviate the destructiveness of accident.Depend on that the length that telescopic pipe 6 stretches out, the length that telescopic pipe 6 stretches out depend on its intraluminal blast again the opportunity that gas generating unit 10 starts, and the size of blast finally depends on the speed that this car travels.The speed of a motor vehicle is high more, and telescopic pipe 6 extension elongations are just long more, and the time that gas generating unit 10 starts just more early.The air door 12 that is arranged on the ventilation inlet 4 can be used to regulate intake, promptly can be used to adjust the relation of the speed of a motor vehicle and telescopic pipe 6 extension elongations under certain meteorological conditions.Because normal, the stable action of telescopic pipe 6 is very important for whole device, so the instrument carrier panel in the car is provided with the demonstration of the situation of stretching out about telescopic pipe 6, so that its working condition is monitored in real time, guarantees the reliability of whole device work.
