Description

A kind of vehicle that back-pressure automatic control anticollision device is installed

Technical field

The present invention relates to a kind of vehicle that back-pressure automatic control anticollision device is installed, belong to auto-industry application controls technical field.

Background technology

At present, vehicle is chased after and is doted on as a kind of vehicle, the safety traffic situation in the whole nation is increasingly serious in recent years, frequent accidents occurs, personal casualty and property damage are heavy, the death toll that traffic accident causes accounts for the more than 90% of various accidents, to the mankind's harm considerably beyond earthquake, flood, these fearful disasters of fire, along with deepening continuously and rapid economic development of policies of reform and opening to the outside world, power actuated vehicle rapidly increases, contradiction between transportation condition and the magnitude of traffic flow, although doing a lot of work aspect prevention road traffic accident, but because the safety traffic law consciousness of traffic participant is thin, safe precaution ability is poor, it is objective that Current Status of Traffic Safety is not still allowed, cause very large loss to the people's lives and properties.

Data show 500,000 of traffic accidents in recent years according to the relevent statistics, because toll on traffic is all over 100,000 people, be equivalent to a small-sized county, rank first in the world, within every 5 minutes, just there is the people wheel of losing one's life, within every 1 minute, all can have a people because of traffic accident and disability, the economic loss causing because of traffic accident every year reaches tens billion of units.

Along with the application market of automobile is increasing, traffic accident emerges in an endless stream so tragic that one cannot bear to look at it, can in development tendency life, be unable to do without again traffic, automobile has become the requisite trip walking-replacing tool of people, but in life, usually there is traffic accident, the traffic accident that two cars clash into can be said everyday and occur, although there is traffic regulations system, constantly strengthen the awareness of safety of chaufeur, safety air bag, insurance etc., all can not reduction accident to damage to person, the vehicle that back-pressure automatic control anticollision device is installed just can; Take precautions against as far as possible the traffic accident that uncertain factor causes, reduce and take place frequently rate to personal injury.

Summary of the invention

The object of the invention is to overcome deficiency of the prior art, a kind of vehicle that back-pressure automatic control anticollision device is installed is provided, in car chassis front and back end two sides, by back-pressure automatic control anticollision device, reduce impact; When two cars approach security alarm letter apart from time, hydraulic control device is opened in infradred sensor indication, the suction arm that will stretch stretches out, in suction pipe, be full of the hydraulic pressure of certain pressure, under the effect of force compresses ratio outside of the hydraulic oil with pressure, produce back-pressure, back-pressure that moment produces is low disappears, dissolves impact energy clashing into; Signal conditioning package is processed the infradred sensor information receiving, when comprising velometer information being greater than 30 kilometers in the infradred sensor information receiving, by conductor wire, to hydraulic control device, carry electric current, connect multistage electromagnetic relief pressure valve, back-pressure automatic control anticollision device enters mode of operation.

[0006] by driving a kind of vehicle that back-pressure automatic control anticollision device is installed, can the personal injury in traffic accident be down to low again, by malleation in back-pressure automatic control anticollision device, under the effect of external force, produce negative pressure, the flexible hydraulic pressure of inhaling in arm is just obtaining negative compression than mutual low disappearing under impact, personal injury degree can be reached for even zero, and traffic accident turns danger into safety.

The left dress arm of force, right support arm can allow the left and right of general vehicle crashproof simultaneously, bogie rollover, the especially left dress arm of force can allow special vehicle have collision prevention function, such as interception function of police car etc., even high speed motor car, also back-pressure automatic control anticollision device further can be designed, while running into emergency case, all power is dissolved as the front and back of motor-car crashproofly by negative pressure, by stretching out the length of the arm of force, carrys out the impulsive force on release rate, can be applicable to various High speed vehicles.

The hydraulic pressure size that in design, arm of force tube chamber enters, plunger stroke, by being the key that produces negative pressure, are calculated the harm that correctly just there will not be impact to occur; Can also prevent to overturn, even turn over, also can lead to the hydraulic function righting of the left dress arm of force, right support arm on sidehill road, not need lifting operation just can win the quality time of rescuing people.

Main technical schemes of the present invention is to realize like this
