Description
Technical field
The present invention relates to a kind of Automobile Products, especially relate to a kind of pedestrian protection system that is used for automobile.
Background technology
According to " People's Republic of China's road traffic accident statistics annual report " data display, the pedestrian's quantity because of the traffic accident unexpected death was 21106 people in 2007, accounted for 25.85% of whole toll on traffics; The city is the district occurred frequently that pedestrian traffic accident takes place, and be example with Beijing, two big cities, Guangzhou: Beijing pedestrian traffic accident casualty rate accounts for 38% of local traffic accident injures and deaths total number of persons, wherein dead 161 people; Guangzhou pedestrian's casualty rate accounts for more than 40%, and wherein death toll is 224 people; The annual traffic injuries and deaths number of China is equivalent to Wenchuan earthquake.
China's automobile pollution end of the year in 2010 has reached 7,400 ten thousand, and wherein the overwhelming majority does not install pedestrian protection system, and the automobile of design pedestrian protection system is arranged at present; Only account for very little ratio; And all be when new car designs, just to design, when car production, just load onto, for example
HondaSing the praises of
RLWith
TL,
Daily outputGTR with
350Z,
InfinitiG37,
CitroenC6,
JaguarVehicles such as XF.If pedestrian protection system will install additional on this design-calculated car not having originally; Because of combining with primary car structure; Be at present difficult point (particularly resemble bonnet and bounce up the formula pedestrian protection system, do not consider during like former car design, hardly maybe after install additional); And China's automobile every day directly collides about 50 people of pedestrian's quantity to death, and how on existing automobile, to install pedestrian protection system additional is problem demanding prompt solution.
Chinese patent CN101607545 discloses a kind of method for protecting pedestrian that is used for automotive front.Said method is at the inwall of automobile protecgulum shock absorber to be installed; The position of said shock absorber is corresponding with the position of following hard components.When automobile and pedestrian bumped, pedestrian's upper body fell on the anterior protecgulum of car, and protecgulum is pressed to following hard object such as engine case etc.These hard components can cause pedestrian's grievous injury under normal conditions; But because following shock absorber has absorbed pedestrian's impact energy, cushioned the bump strength of hard components now, thereby reached protection pedestrian's effect the pedestrian.
Chinese patent CN101077704 discloses a kind of automobile front beam pedestrian protecting equipment special-purpose, and said pedestrian protection is installed in the bottom of the front bumper assembly of automobile through support; Pedestrian protection adopts thin material and newly-designed structure; Reduce the impact site height,, reduce to clash into strength with the impact process of control to shank; Guarantee that simultaneously energy absorbing coordinates with front bumper mutually, thereby ensure that effectively pedestrian's knee, leg avoid grievous injury.
Chinese patent CN1931638 discloses a kind of automobile that comprises pedestrian protection, and said pedestrian protection comprises control unit, source of the gas and airbag, and said control unit is electrically connected with source of the gas, and said source of the gas communicates with airbag; Wherein, Car bonnet is connected for opening with vehicle body near front windshield one side; Folding being placed in car bonnet when said airbag does not launch near front windshield one side; Airbag is tiled on the front windshield during expansion, and the part of the airbag that launches is positioned at the car bonnet opened and forms down and to car bonnet and support.
Summary of the invention
The object of the present invention is to provide and a kind ofly avoid or reduce that the pedestrian dies or the injured pedestrian protection system that is used for automobile in traffic accident.
The present invention is provided with preceding safety pad air bag, bonnet safety pad air bag, acceleration pick-up, BARO sensor, ECU, preceding safety pad air valve, bonnet safety pad air valve and air pump; Preceding safety pad air bag is connected with air pump with tracheae through preceding safety pad air valve, and bonnet safety pad air bag is connected with air pump with tracheae through bonnet safety pad air valve; Acceleration pick-up and BARO sensor are contained in preceding safety pad air bag and the bonnet safety pad air bag; The signal output part of acceleration pick-up and the signal output part of BARO sensor connect the input end of ECU respectively; The preceding safety pad Air Valve Control signal output part of ECU, the gentle pump control signal mouth of bonnet safety pad Air Valve Control signal output part are connected with preceding safety pad air valve input end, the gentle pump control signal input end of bonnet safety pad air valve input end respectively; Safety pad air bag and bonnet safety pad air bag before preceding safety pad air valve mouth, bonnet safety pad air valve mouth connect respectively, preceding safety pad air valve input end and bonnet safety pad air valve input end connect the pressurized air mouth of air pump respectively.
The safety pad air bag can adopt inflatable rubber and plastic air bag etc. before said, and said bonnet safety pad air bag also can adopt inflatable rubber and plastic air bag etc.
The safety pad air bag can be provided with at least one in left inflatable preceding safety pad air bag, right inflatable preceding safety pad air bag, the middle preceding safety pad air bag etc. before said, and the inflatable preceding safety pad air bag in a said left side, right inflatable preceding safety pad air bag and middle preceding safety pad air bag can be communicated with also can be independent.
Because main body of the present invention is inflatable rubber and plastic air bag; When vehicle start went, ECU received the signal from acceleration pick-up, when the speed of a motor vehicle surpasses setting value (like 5km/h); The air pump that the ECU control vehicle carries (is not worn air pump like former car; One in palpus new clothes) to airbag aeration, air bag stretches out the about 0.1～0.3m of front end of vehicle automatically before making, and the atmospheric pressure value in the air bag can be passed to ECU through BARO sensor; When air pressure reached setting value, ECU control air pump stopped inflation, in case vehicle and the place ahead human body bump against, air bag plays buffer action.
Also be provided with bonnet safety pad air bag owing to protect; Said bonnet safety pad air bag is positioned at bonnet end (front, front windshield bottom); Therefore when translating into behind the pedestrian impact when rolling on the bonnet to front windshield; Can cover fatal " hard spots " such as front windshield bottom, rain brush balance staff and bonnet bearing, reduce the degree of pedestrian's secondary collision.
Behind vehicle parking, ECU can be controlled the outside exhaust of air valve of air bag, is loaded on the spring between air bag front end and the vehicle body simultaneously, with the anterior withdrawal of air bag.
The present invention is portable strong, is applicable to all kinds of cars, and cost is lower simultaneously, is applicable to general automobiles consumer groups, and popularization is preferably arranged.When the front end of automobile was thrusted into, the inflation safety pad played buffering on the one hand and even avoids taking place the effect of major accident; Sensor on the while safety pad; To automobile electric control system (driving engine and brake system etc.) information is provided; Impel automobile flameout, brake; Avoid resembling the generation of " the drunk chaufeur of driving to thrust into but do not have sensation and do not take brake " this phenomenon, reduce the loss of people's lives and properties effectively.
