detailed description of the invention
In order to understand better originally according to the anti-collision air bag of utility model, be further elaborated explanation below in conjunction with the preferred embodiment of accompanying drawing to the anti-collision air bag in the utility model.
As shown in Figures 1 and 2, a kind of anti-collision air bag, is placed in air bag groove (for brevity, these parts not shown of car body outside, but this can not affect understanding of the present utility model), be placed in the air bag of air bag groove, described anti-collision air bag also comprises pressure sensor.The pressure sensor that the preferred embodiment of the anti-collision air bag that the utility model provides adopts is deposition tube resistance type sensor.Deposition tube resistance type pressure sensor forms semiconductor strain pressure on semiconductor membrane surface, by external force (pressure), semiconductor membrane is out of shape and produces Piezoelectric Impedance effect, thus making the change of impedance convert electric signal to.The reason adopting deposition tube resistance type pressure sensor is that traditional pressure sensor is based on the device of physical construction type, and with the deformation indicated pressure of elastic element, the pressure sensor dimensions of this structure is large, quality light, and electricity can not be provided to export.The preferred embodiment of the anti-collision air bag that the utility model provides adopts the usefulness of deposition tube resistance type pressure sensor to be that deposition tube resistance type pressure sensor volume is little, quality is light, accuracy is high, good temp characteristic, power consumption are little, reliability is high.Battery power in master controller and vehicle remains "on" position, and guaranteeing that vehicle collides at any time can react in time and take countrmeasure.
The pressure sensor of the anti-collision air bag that the utility model provides conducts electricity with controller and is connected.Pressure sensor is subject to ambient pressure when doing, and forms quartz conductor deformation pressure on semiconductor membrane surface, and by pressure, semiconductor membrane be out of shape and produce Piezoelectric Impedance effect, further pressure sensor makes the change of impedance convert electric signal to.Electric signal is reached controller by pressure sensor, the electric signal of micro controller system processing pressure sensor in controller.The signal of controller process is sent to air bag priming device by start-up circuit.Fire lighter ignited by air bag priming device, makes gas generator generation chemical reaction in air bag explosive device and produces gas.Gas is filled with in the middle of the air bag that is threaded with air bag priming device by ventilation flue, described air bag is inflated from described air bag priming device, described air bag is ejected from described air bag groove, the harm brought to the navigating mate in vehicle and passenger when slowing down collision.
Start-up circuit is provided with in the controller of the preferred embodiment of the anti-collision air bag that the utility model provides.When collision happens, the signal of sensor is sent to controller, and the signal of controller processes sensor also transfers to described air bag priming device by start-up circuit.Start-up circuit in controller be independent action in described air bag priming device, according to the start-up circuit of this kind of patten's design can make air bag can be pointed inflate, the position of installing according to sensor and then the air bag of relevant position of detonating.The usefulness of the start-up circuit designed in this way is: the preferred embodiment of the anti-collision air bag that the utility model is provided can be more targeted to the air bag detonated, reach the air bag that correspondence position is subject to sensor to detonate, and the object that the air bag of other positions does not detonate, so more can reach the object of economize energy.
What sensor adopted is semiconductor pressure sensor.Traditional pressure sensor, based on the device of physical construction type, can not provide electricity to export with the deformation indicated pressure of elastic element.And semiconductor pressure sensor is simple and reliable for structure, do not have relative movement part, pressure-sensing device and the elastic element of sensor are integrated, and eliminate mechanical hysteresis and creep, provide electricity to export, and improve the performance of sensor.
The air bag priming device of the anti-collision air bag that the utility model provides is inflated independent air bag.Be provided with start-up circuit in controller, and each start-up circuit is separate, each independently start-up circuit only implement to detonate operation for an independent air bag priming device.Independent air bag priming device implements independent inflatable to each air bag.Arrange in this manner, can to detonate action to the air bag of vehicle collision position timely and effectively.Vehicle ad-hoc location is impacted, then the sensor of this ad-hoc location produces the change of impedance, makes the change of impedance be converted to electric signal and is sent to controller, and the electric signal of master controller receiving sensor is gone forward side by side row relax.Signal via master controller process is sent to the air bag priming device corresponding with the sensor at this particular crash place.The instruction that this specific air bag priming device receives controller is carried out fuze and is filled into by the gas of generation in the middle of air bag that admission port is threaded with this air bag priming device air extractor duct, and then reach vehicle ad-hoc location and be subject to impacting, just the air bag of this position effect of detonating, avoids ad-hoc location to be subject to impacting rear whole air bag and detonates simultaneously.If ad-hoc location is impacted and causes whole air bags to detonate, also can there is second accident in some cases, cause more serious consequence to other staff in navigating mate and vehicle.
Sensor is arranged on automobile buffer beam, and sensor installation can alleviate timely and effectively and damaged to navigating mate in car and other passengers because vehicle impacts in this way.Collision prevention of vehicle beam is the girder construction in order to protect vehicle and occupant to be subject to less or not to be damaged and to arrange.Sensor is arranged in the collision prevention girders of vehicle by the anti-collision air bag preferred embodiment that the utility model provides; when vehicle is subject to impacting; except the vehicle body of collision prevention girders to vehicle plays except certain guaranteeing role, the anti-collision air bag that the utility model provides also can play the protection to automobile body.What sensor adopted is the sensor of semiconductor-type, is quick on the draw, further ensure that vehicle and occupant escape injury.
The air bag of the preferred embodiment of the anti-collision air bag that the utility model provides is complete shaping coated fabric air bag, 420 dawn nylon66 fiber silks silicone-coating.Adopt this kind of material to make air bag and have good physical and mechanical properties, intensity is high, quality is light, and frictional behaviour is good, and elasticity is strong.Also have high chemical inertness, resistance to aging, the air bag of the anti-collision air bag preferred embodiment that the utility model is provided can use muchly, and can play a role timely and effectively when vehicle is subject to impacting.Intensity is high, good springiness is again for vehicle interior navigating mate and the safety of other passengers when vehicle occurs to impact add one deck safety control.
More than be described in detail in conjunction with specific embodiment of the utility model, but be not to restriction of the present utility model, such as described number of sensors number and described sensor install position, the shape etc. of air bag, everyly according to technical spirit of the present utility model, technical scope of the present utility model is all belonged to any simple modification made for any of the above embodiments, also it should be noted that, comprise the combination in any between each part mentioned above according to the category of anti-collision air bag technical scheme of the present utility model.
