Abstract
The invention aims at realizing an automobile anti-collision system capable of greatly improving the medium-low speed safety of an automobile. The system consists of two parts, namely a control system and an anti-collision buffer system. Data is acquired by a distance measuring sensor and a speed measuring sensor of the control system and is transmitted to a data acquisition and processing circuit; and the processing circuit firstly judges whether a control circuit is started. When the control circuit is needed to be started, the control circuit opens an electric valve; and an airbag is charged by a gas storage bottle of a brake system. The airbag ejects out after pushing away a baffle so as to exert the buffering action. When the collision occurs, an air escape valve is opened to discharge the air; the air bag is put back into the baffle manually; and the gas bottle charges the airbag again and the automobile is restored to a next working status. The automobile anti-collision system can be installed before a novel automobile leaves a factory or be installed through the repacking of the prior automobile so as to prevent and reduce the damage to the automobile caused by collision. The automobile anti-collision system is simple, feasible, economical and practical without affecting the appearance of the automobile.
Description
Technical field
The present invention relates to a kind of collision avoidance system of automobile; common riding in an automobile-quality≤the 2000Kg in the centering low speed driving particularly; the anticollision device of speed≤60km/h-protect, this device can also can add repacking to existing automobile easily in the new car production preceding installation of dispatching from the factory.
Background technology
Along with modern society's rapid development of economy, automobile has become the requisite vehicle in people's life, and traffic safety problem also becomes one of problem demanding prompt solution.To the analysis showed that of traffic accident, the vehicle collision above 65% belongs to knocks into the back or similar collision, and the generation that reduces this class accident can reduce the incidence of traffic accident greatly.The measure of taking at present is the safety that the people is taken in air bag protection safe in utilization, does not also have real adaptable product to occur at the damage this respect that prevents vehicle.The research of existing guard technology to automobile has two general orientation: the one, and by auto alarm, self-actuating brake, the automatic speed reducing system of pure circuit control, the advantage of this system is to prevent trouble before it happens, and shortcoming is that disturbed by external condition big, and reliability is not high; Another kind is the buffer system of Purely mechanical, begins to work after two cars bumps against together, reduces the damage to car, this system reliability height, but huge to the refitting engineer of car body, cost is higher.Therefore, can reduce the loss of collision effectively, and economical and practical, simple and easy to do anti-collision system for automobile waits to realize.
Summary of the invention
The objective of the invention is to have realized a kind of, high reliability, install additional easy, can be repeatedly used and the anti-collision system for automobile of safety can significantly improve low speed driving in the automobile time, this system is made up of control system and crashproof buffer system two parts.Wherein control system is made up of distance measuring sensor and tachogenerator, data acquisition, treatment circuit and control circuit three parts that contain motorized valve, and crashproof buffer system comprises baffle plate, air bag and gaholder.
Anti-collision system for automobile of the present invention, its technical scheme is: distance measuring sensor and the tachogenerator image data by control system at first, be sent to the data acquisition and processing (DAP) circuit, whether treatment circuit at first judges the start-up control circuit; When needing the start-up control circuit, control circuit is opened motorized valve, and the gaholder of crashproof buffer system is to airbag aeration at this moment.Air bag ejects after backing down baffle plate, plays the effect of buffering.Collision is opened aie escape valve later, discharges gas, manually air bag is rolled and is put back in the baffle plate, and gaholder is inflated once more, and automobile returns to next mode of operation.
The distance measuring sensor of control system adopts the ultrasonic ranging sensor in the anti-collision system for automobile of the present invention, promptly utilizes ultrasonic transmitter emission super sonic, picks up counting simultaneously, receives that to ultrasonic receiver backward wave stops.According to the time t of timer record, can calculate launch point apart from obstacle apart from s, that is: s=340t/2.
The crashproof buffer system of anti-collision system for automobile of the present invention is achieved in that and is cavity in the bumper/spoiler, bumper/spoiler with the headlight below cuts a part respectively, the wedge shape air bag curled put into wherein, the inner side of air bag shortens a ply-yarn drill in hollow tubular, hollow tubular is stuck in by being bolted in the square steel tank in the car, and the baffle plate that air bag external application and bumper/spoiler cooperate blocks.Gaholder be the glass steel in adorn compressed-air actuated high-pressure gas cylinder, be fixed on the perch of front truck beam inboard, be airbag aeration when motorized valve is opened.Baffle plate top is hollow cylinder, makes Spring hinge and is used for being connected with bumper/spoiler.The effect of spring is inwardly to draw baffle plate, and it can not opened in normal vehicle operation.
Preferably, the tachogenerator of anti-collision system for automobile of the present invention adopts hell integrated sensor, and the data acquisition and processing (DAP) circuit adopts 51 micro controller systems, and sensor and micro controller system insert the circuit in the car, by the storage battery power supply.Ultrasonic waves transmitted is modulated into 40kHz, has the modulating pulse wave signal of certain intervals, micro controller system is that 25um/us, carrier wave are the ultrasonic pulse string of 40kHz by the external pin output pulse width, be added to the ground level of emitter follower, promote ultrasonic transmitter through power gain and launch, the effective propagation distance of the impulse singla of emission is 6 meters.Ultrasonic receiver is delivered to amplifier with the reflection supersonic wave that receives and is amplified, and carries out detection with phase-locked loop circuit then.Output low level is delivered to micro controller system after treatment, and the signal of micro controller system inquiry tachogenerator compares calculating in conjunction with the signal of ultrasonic receiver, makes corresponding judgment, and motorized valve is carried out control corresponding.
The gaholder of crashproof buffer system is placed near the cooling pipe of engine, selects for use glass-felt plastic to make, and allowable pressure is 3 * 10
6-5 * 10
6Between the handkerchief, volume is 5L.Air bag selects for use duck to make, and internal layer coat with rubber or resin are to guarantee its air-tightness, and its allowable pressure is 3 barometric pressures, and maximum pressure is 4.5 barometric pressures, and each air bag volume is 110L.Air bag is established aie escape valve being provided with an inflation inlet near a jiao of steel pipe on diagonal line, when intraluminal pressure surpasses 4.3 barometric pressures, can automatic release gas to prolong surge time.Both sides, the top punching of bumper/spoiler otch, the mounting spring hinge.The Spring hinge of baffle plate when mounted, on excellent core, excellent core is longer than baffle plate 6mm with iron wire, and the excellent core that is wound with iron wire is through in the circular hole of baffle plate, reserves the face that puts both ends of the production process of iron wire, then excellent core two is injected in the aperture of reserving on the bumper/spoiler.
Anti-collision system for automobile of the present invention can prevent and reduce the damage that hard collision causes to automobile, and simple and feasible, economical and practical, does not influence the attractive in appearance of vehicle.
