Abstract

An air bag type anti-collision bumper of car features that a U-shaped (or other shapes) air bag made of metal or non-metal material is installed to the front, back and both sides of a car and then inflated with air. When collision occurs, the air bag deforms and the air pressure in the bag is raised up to suck the most of collision energy, ensuring high safety.

Description

Air bag-type anticollision bumper of car

The invention belongs to car accessories, relate in particular to a kind of bumper/spoiler that is used for automobile collision preventing.

At present, be used for the method for automobile collision preventing with protection driver and passenger's safety, except the front-end and back-end of automobile dress metal or plastic housing bumper/spoiler, now more is at driver and passenger's seat front end inflatable airbags to be housed.At the front-end and back-end of automobile dress metal or plastic housing bumper/spoiler, though when colliding, can absorb partly energy, but,, often do not have the crashproof effect of automobile when fair speed so the absorption energy is less because it is to lean against the metal of bumper/spoiler when colliding or plastic deformation to come endergonicly.And at driver and passenger-seat front end dress inflatable safety air bag; it is strenuous vibration when automobile take place to be collided or automobile strong deformation and make the explosive inflation of safety air bag; driver and passenger and automobile are separated; thereby cause driver or the passenger buffering when colliding, reach protection driver and passenger's purpose of safety.Though this method has safe effect preferably; but often the basis for estimation and the standard of the time of airbag opening and triggering airbag opening are difficult to accomplish accurately; sometimes safety air bag is opened the effect that does not have protection driver and passenger safety too late, and slight sometimes collision may be opened safety air bag by mistake.In addition, trigger and open because this safety air bag is strenuous vibration when automobile is collided and strong deformation, thus be the protection scheme of passive type, rather than when colliding a large amount of absorb energy avoid automobile impaired with the active measures of protecting driver and passenger safety.

Purpose of the present invention is exactly in order to address the above problem, a kind of air bag-type anticollision bumper of car is provided, it not only can absorb energy in a large number and reduce the infringement of automobile and improve driver and passenger's safety in automobile collision process, and the accurate foundation and the standard that can provide the safety air bag of driver and passenger's front end to open.

The present invention is achieved in that it is in the front end of automobile or rear end or the one or more U-shapeds made from metal or non-metallic material or tubulose or other shape pressure bladder of other shape are installed in the side, on this pressure bladder, be equipped be attached thereto logical compression indicator and with automobile or the same or analogous turnover valve of bike tyre; Also can communicate with the controller of the safety air bag before a tracheae and driver and the passenger-seat, this moment, the pressure that is transmitted by this root tracheae of opening of safety air bag was controlled.During use, the present invention is loaded on front end or the rear end or the side of automobile, inwardly injects air by dress turnover valve thereon then, make it the pressure that reaches certain.When taking place to collide, because the pressure bladder that is loaded on the automobile can deform, the air pressure in the pressure bladder is raise, thereby stop the further distortion of pressure bladder.Energy during collision is big more; the deflection of its pressure bladder is just big more; air pressure in it raises just big more; unless collision energy and intensity are very big; make pressure bladder when distortion; air pressure in it increases to pressure bladder and can't bear and cause explosion, otherwise pressure bladder can be when colliding raises to reach and absorb big energy by self distortion and the air pressure in it, reaches the purpose that reduces automobile impaired and protection driver and passenger safety.If what pressure bladder adopted is the non-metallic material manufacturing bigger as plasticity such as rubber, then after the end of colliding, under the pressure bladder pressure effect within it, return to the original form very soon; If pressure bladder adopts plastic relatively poor material manufacture such as corrosion-resistant steel or carbon steel, then after the end of colliding, under the pressure bladder gas pressure within it, can partly recover the shape of sealed bladder, but be difficult to recover fully its original shape.On the other hand, owing to can judge the energy of collision and the size of intensity, thereby can utilize these characteristics to control to be loaded on opening of safety air bag before driver and the passenger-seat with the deflection of pressure bladder and interior air pressure thereof the size that raises.Just when the air pressure in the pressure bladder is being collided, rise very highly suddenly; this moment collide energy and intensity of explanation is bigger exactly; when its air pressure rises to a certain setting value; the safety air bag that safety air sac controller will be loaded on before driver and the passenger is opened, to reach the purpose of safety of further protecting driver and passenger.And it is less to raise when the air pressure in the pressure bladder is being collided, energy and intensity that its collision then is described are very little, the safety air bag that the interior air pressure of pressure bladder this moment can not will be loaded on before driver and the passenger is opened, as long as just all absorbing the collision energy, the less distortion of pressure bladder guarantees driver and passenger's safety this moment, then need not further airbag opening, like this, being loaded on the preceding safety air bag of driver and passenger has just had a precise opening foundation and standard, thereby makes opening of safety air bag more accurately reliable.

Owing to adopt such scheme; the pressure bladder that is loaded on automotive front end or rear end or side will raise and energy will collide the time absorbs in a large number owing to distortion and the air pressure in it of self, thereby reduces the infringement of automobile and reach the purpose of protecting driver and passenger safety.On the other hand, owing to judge the energy of collision and the size of intensity with the deflection of pressure bladder and the size of internal gas pressure rising thereof, so can utilize these characteristics to control to be loaded on the safety air bag before driver and the passenger whether to open, thereby safety air bag provides a precise opening foundation and standard for this reason.
