Abstract
A method of actively reducing injury and damage of automobile collision accident is to set air bag in both front and back bumpers. The obstacles before and behind the automobile are monitored by means of velocity radar and the speed of the obstacles and the automobile itself are compared. In case of emergency, the air bags are opened out to protect person and automobile. The present invention can protect automobile, pedestrians and other vehicles.
Description
The invention belongs to a kind of safety guard for automobile.
Automobile has become obligato instrument in people's daily life, and as the various accidents that automobile brought, has also become important social concern thereupon as the representative of big industrial civilization.Show that according to pertinent data because the personal casualty that car accedent caused has reached up to ten million person-times, the property damage of Yin Faing is then huge especially therefrom.Therefore, the safety of automobile become present auto-industry the problem extraordinarily paid close attention to.
From present technical classification, nothing more than the approach that following several respects are arranged: 1, strengthen the intensity of car stand itself, and design has deforming zone attraction Impact energy.2, safe automobile air bag is installed in car, when colliding, is discharged with the protection passenger safety.3, the generation that utilizes electronics package early warning collision that abroad embarks now, control is in advance slowed down even brake.
Above several method is that its pros and cons are respectively arranged naturally.
The prerequisite that present air bag discharges all is that actual collision has taken place is prerequisite with automobile, and following several disadvantage is so just arranged.At first be after collision takes place, airbag actuation, to effect takes place, therefore time is very limited, control system is required just than higher, opens the personnel that cause easily and injures and air bag is too fast, in addition, the property damage of automobile itself is unavoidable, and, be invalid to the pedestrian when this method bumps against for self-propelled vehicle and people.
The objective of the invention is to reality many at the present pedestrian of China, that bicycle is many, consider protection simultaneously, thereby a kind of method and apparatus that can initiatively alleviate automobile collision accident injury and loss is provided automobile itself.
The objective of the invention is to realize in the following way:
This method adopts detection path: IC5, the path that IC2 forms is responsible for inspection vehicle fwd unforeseen circumstances, it is characterized in that: it is the power supply of 12V that the power supply that IC4 obtains from automobile storage battery forms constant potential, the supply entire circuit is used, IC5 detects the impulse singla of automobile driving speed, and from pin 7, voltage signal that changes with impulse rate of pin 4 outputs, IC2B forms a voltage comparator, this voltage signal is monitored, when the speed of a motor vehicle is higher than a certain setting value, this voltage signal also arrives certain setting value, can make pin 7 outputs one high level, simultaneously, the voltage comparator that uses IC2A to form, monitoring automobile and front obstacle apart from situation, the signal that its X1 connection range only radar provides.When the distance of obstacle reached setting value, IC2A pin 1 was an exportable positive signal, and two positive signals make the IC1A conducting, drove the M1 conducting, caused air bag F1 inflation.
This device comprises the air bag that is located on the Federal bumper, and the air bag on the front bumper can be one group, is located in the bumper/spoiler, and the air bag on the rear bumper can be one group, is located in the bumper/spoiler.
Air bag both can adopt the high-pressure gas bottle inflation, also can adopt chemical reaction to discharge gas.
Can be cellular structure between the major and minor thick stick of front bumper.
Air bag also can be located in the car.
The present invention has following advantage:
When being in an emergency, the present invention can make air bag initiatively open outside bumper/spoiler, implements protection; greatly alleviated the harm of automobile, also protected car body simultaneously, alleviated damage pedestrian or unpowered vehicle; existing vehicle structure is not changed as extensive, and it is convenient to install, change, and use cost is low.
Below in conjunction with accompanying drawing invention is described further:
Fig. 1 is a principle of the invention block diagram;
Fig. 2 is control circuit figure of the present invention;
Fig. 3 is an air bag installation site front view;
Fig. 4 is the birds-eye view of Fig. 3;
Fig. 5 is a utility van airbag-releasing scheme drawing;
Fig. 6 is a small passenger car airbag-releasing scheme drawing;
Fig. 7 is the embodiment that air bag is installed.
See Fig. 2:
This circuit is made up of the two-way detection path: the path that IC5, IC2 form is responsible for inspection vehicle front unforeseen circumstances; The path that IC6, IC3 form is responsible for the unforeseen circumstances of inspection vehicle back.
This method adopts detection path: IC5, the path that IC2 forms is responsible for inspection vehicle fwd unforeseen circumstances, it is the power supply of 12V that the power supply that IC4 obtains from automobile storage battery forms constant potential, the supply entire circuit is used, IC5 detects the impulse singla of automobile driving speed, and from pin 7, voltage signal that changes with impulse rate of pin 4 outputs, IC2B forms a voltage comparator, this voltage signal is monitored, when the speed of a motor vehicle is higher than a certain setting value, this voltage signal also arrives certain setting value, can make pin 7 outputs one high level, simultaneously, the voltage comparator that uses IC2A to form, monitoring automobile and front obstacle apart from situation, the signal that its X1 connection range only radar provides.When the distance of obstacle reached setting value, IC2A pin 1 was an exportable positive signal, and two positive signals make the IC1A conducting, drove the MI conducting, caused air bag F1 inflation.
IC6, the path that IC3 forms is responsible for the unforeseen circumstances of inspection vehicle back, IC6 detects the moving velocity of automobile, and from voltage signal that changes with impulse rate of pin 1 output, IC3B forms a voltage comparator, this voltage signal is monitored, when reaching setting value, IC3B pin 7 has voltage output, use simultaneously IC3A form voltage comparator monitoring automobile and back obstacle apart from situation, its X2 connects the signal of finding range and providing from radar, when the distance of obstacle reaches setting value, pin 1 is an exportable positive signal, and two positive signals make the IC3A conducting, drive IC 1B conducting, and then drive the M2 conducting, cause the F2 airbag aeration.
Fig. 3, air bag shown in Figure 4 are installed in three places, left, center, right of front bumper.
Behind the utility van airbag-releasing shown in Figure 5, before and after car, form air cushion.
Before and after car, form air cushion behind the small passenger car airbag-releasing shown in Figure 6.
See Fig. 7, wherein: (1) main thick stick; (2) air bag; (3) cellular material.
Air bag adopts the high-pressure gas bottle inflation, can utilize electromagnetic valve to open valve, and the while air bag backs down baffle plate and is opened.The air bag baffle plate can have two kinds of mounting meanss on bumper/spoiler, a kind of the place ahead, air bag of being positioned on is to front opening (being suitable for small passenger car); Another kind is positioned on the top, air bag is upwards opened (being suitable for utility van).
The invention is not restricted to above embodiment, all mode or device at automobile front and rear baffle external opening air bag all belong to protection scope of the present invention.
