External record the collide response time of signal of sensor detection pedestrian with dummy's analogue test and should be 20ms, point of ignition is 2ms, and it is 3ms that gas begins efflux time, and the airbag aeration expansion time is 30ms, and cumulative hours is 55ms.
Improve the essentiality of automobile self-protection performance, can just have been come as can be seen the reaction time of emergency event by the reason of chaufeur and vehicle itself.
1. because galloping, the reaction time that completely reacted chaufeur is general under people's the reaction time normal circumstances when having an accident is between 0.4-0.6s.Chaufeur is subjected to the most meeting of critical scaring the reaction time greater than 1s, even produces the mistake that throttle is stepped on when brake.It is normal with interior genus to be reflected at 1.5s, is considered to mal when surpassing 2s.When automobile travelled with the speed of 50/h, swift chaufeur can be made right judgement about 6-7m, and had taked the action of braking; And react slow, and then needing more than 12-14m, just to make right judgement and action, many burst accidents have often had little time to have prevented under the slow situation of reaction so.
2. brake system response time.Chaufeur begins to depress brake pedal to end of braking, and the overall process of automobile brake comprises: the reaction time of Ta brake system, Tb drg onset time (coordinated time), Tc continue braking time, Td loosen the brake device four-stage.
A. reaction time of brake system.Along with the action of chaufeur pedal, pedal overcomes play motion, brake clearance required time, and the reaction time of general hydraulic brake system is that Ta is 0.015s-0.03s.This time automobile does not have decelerated movement.
B. drg onset time.The drg onset time, the fast speed processed of brake-pressure was increased to maxim through behind the Tb, and the onset time Tb of general hydraulic brake system is 0.15s-0.3s.This time automobile has decelerated movement.
C.Tc is for continuing braking time, and relatively stable at this section period inside brake deceleration/decel, Td is the loosen the brake device time, and at this section chaufeur loosen the brake pedal in the time, braking procedure finishes.Braking drop away time must not be greater than 0.8s.
Under normal circumstances, when having an accident, the occupant tends to be subjected to serious more than once injury.When bumping, the undergoing mutation property of speed of vehicle reduce sharply the in other words conj.or perhaps sharp increase of mutability.And violent collision can take place with car body because inertial acceleration is excessive in occupant forward or backward, causes the occupant to be subjected to serious injury.Or huge acceleration/accel makes fracture of cervical spine pressuring nerve, safety strap compressing internal organ cause the visceral rupture massive haemorrhage to cause the injures and deaths event.What vehicle took place under the situation mostly is rigid collision, and the kinetic energy transmission is very violent.The steel framed structure of car body can absorb energy greatly, thereby cause car body generation serious deformation owing to violent bump.After the accident that the summary express highway takes place, find, most of personal casualty are clashed into the back because inertia and car body bump extremely at vehicle, but very serious deformation has taken place in vehicle, personnel in the compressing car, cause personnel to be confined in the car internal haemorrhage and excessively can not launch to save oneself, the follow-up rescue strength that should come is also because the serious deformation of car body can't in time be implemented relief to trapped personnel.This shows that the distortion of car body not only causes the stranded of personnel, salvage work can't be carried out, lose the good chance of relief, can't change the generation of tragedy.The safety air bag that assembles on the existing vehicle is mounted in car body inside mostly, belongs to passive security.And collided the back effect.Buffering and the absorption of energy when so we will set about finding a kind of way initiatively to solve the bump generation, and protect car body to be unlikely to take place passenger life is caused safely the deformation of serious harm as much as possible.
Summary of the invention
The utility model is a kind of safety air bag Active Defending System Against, belongs to active safety.Direct injury and secondary injury to personnel when putting forth effort to reduce automobile generation burst accident, the safety factor of increase vehicle reduces car body deformation, guarantees personnel's life security to a certain extent for rescue gains time.Owing to consider the problem of cost when in fact air bag is applied to, can not can both be equipped with the safety air bag Active Defending System Against by all vehicles.So, the utility model is design basis with the sport car of certain model, fast at speed, configuration is higher, the security needs design (selected vehicle is Mazda XM-5, and the automobile sign among the figure is removed) of the demanding sport car of safety factor or performance-oriented vehicle.And what the utility model designed mainly is at the outer Active Defending System Against of car body, for car body inside, still adopts existing protection to be equipped with, and improves safety factor in conjunction with outside protection, reaches predetermined purpose.Improve the active safety performance of automobile, constituted by measuring sonde, air bag component, annunciator, read-out etc.The air bag of safe automobile air bag Active Defending System Against is positioned at outside the car body, and measuring sonde is installed in around the car body; Measuring sonde records rammer and the relative velocity of self and distance, and data give treater to calculate, and calculate safety distance by treater, judges whether ignition trigger air bag and the opportunity that starts air bag according to safety distance and relative velocity then; Judge that when treater vehicle is under the dangerous situation, siren horn warning reminding chaufeur slows down or carries out the preparation of dodging.Treater is handled data, and the real-time obstacle position display that car is outer is eliminated the vision blind area of chaufeur on read-out.The air bag of safe automobile air bag Active Defending System Against is positioned at the car body outside, around car body; The data computation that treater records according to measuring sonde goes out relative velocity and safety distance, initiatively starts air bag, shock absorbing power before bump takes place.Preposition air bag and preceding outside air bag start when cooperatively interacting work together, and impulsive force is disperseed along bumper/spoiler, and the equalization impulsive force reaches the buffer action maximization.Reach the dangerous situation of setting when vehicle travels, the safe automobile air bag Active Defending System Against is finished startup automatically, rapidly, and response time is much smaller than the required time of artificial treatment.In the time of outside air bag protection automobile side, with the impulsive force equalization, at utmost reduce car body deformation, car door can be opened, and personnel succour capable.On the hand rear bumper of rearmounted air bag position, when sensing the dangerous signal in back, alarm equipment alarm, treater is judged startup air bag automatically in the time surpassing safety distance, if Vehicular body front or side are clashed into, rearmounted air bag also can start, and reduces the injury of knocking into the back and causing.
