Description
Collision safety system for vehicles of the present invention is a kind of safety system that is used on the various vehicle.Present automobile is existing to stretch out long bumper/spoiler with the increase safety, but can not bounce back.Existing plastics bumper/spoiler is used for automobile to alleviate car weight.There is the automobile buffering device of band subframe in the Soviet Union, but will increase the length of car.There is a kind of automobile buffering device that separates with diaphragm with the liquid air cavity in the U.S., all wants broken but collide diaphragm at every turn.The present invention mainly is in order to guarantee safety traffic, but also for easy to use, comformability is strong, looks after user's custom.
The present invention can be divided into host buffer system and auxiliary safety device, the former is divided into four parts again, and its frame part comprises outer thick stick (being made up of soft thick stick 1, the hard thick stick 2 of non-metal, metallic hard thick stick 3) vertical pole (being made up of piston rod 4, piston 5, clamp pad 6, pilot bar 7) and interior thick stick 8; Assistant cylinder partly comprises assistant cylinder 9, it is protruding 10 to install, pipeline connection port; Pipeline valve comprises partly that total inlet pipe 11, valve F1, F2, branched inlet pipe 12, logical table pipe 13, compression indicator 14, auxiliary tube 15, auxiliary valve F3, automatic air pressure keep that mechanism, interior leak-off pipe 16, eduction valve 17, earial drainage are in charge of 18, outer leak-off pipe 19, drain tube 20, outflow valve 21; Extention comprises outer thick stick indicator lamp 22, electric wire distributor 23, control pin 24, carries pin line 25.Another part is an auxiliary safety device, comprises safety air bag, dead-man's device, fuel oil multiviscosisty device, collision warning equipment.
Working process of the present invention and principle are as follows: doing buffer medium with gas is example, at first open air inlet valve F1 and control pin 24, close auxiliary valve F3 and eduction valve 17 simultaneously, have the air-flow of certain pressure to enter air inlet pipe 11, check valve F2 opens automatically, gas advances the back cavity of assistant cylinder 9 through branched inlet pipe 12, promoting piston 5 advances, the gas of assistant cylinder ante-chamber is compressed through exhaust charge 18, freeing pipe 20, blow off valve 21 and discharges, to guarantee that piston 5 advances smoothly, it is overhanging to promote piston rod 4 and outer thick stick, and pilot bar 7 and interior thick stick 8 are also driven simultaneously.If middle control pin is not mentioned, interior thick stick 8 just is stuck in this position and can not continues to stretch out and can not return automatically when advancing.In case the control pin in the middle of during collision can make framework return again, if middle control pin is mentioned, framework just reaches the longest position, and interior thick stick just is stuck on the control pin of the longest position.When colliding, 1 buffer action of at first soft thick stick, mainly be to prevent the pedestrian that damages, proceed if collide then move the resistance that to break through the control pin in the whole framework and retreat, piston 5 moves in assistant cylinder, compressing inner chamber gas becomes the positive pressure gas spring, draws back exocoel gas and becomes the negative pressure gas spring, thereby make a part of percussion energy be transformed into elastic force potential energy.Because the difference of pressure of interior exocoel forces gas to enter exocoel from inner chamber through pipeline and eduction valve 17, overcomes the resistance of pipeline and eduction valve 17, the acting heat production is with a part of percussion energy that dissipates.Have bigger friction drag between piston 5 and the casing wall and also can absorb part energy, flexible so elastic reaction piston when fluid-suppressing effect is not enough of piston 5 itself is in the inner end surface of assistant cylinder 9 and buffer action, the interior radially inner side of assistant cylinder 6 dwindles gradually, and also thickening gradually of casing wall.When the above buffer action of serious collision was all not enough, the installation of assistant cylinder protruding 10 just overcomes resistance in mounting hole moved, and also can absorb energy.Some gas starts auxiliary safety device through auxiliary line during collision.In order to obtain the optimized buffer effect, can estimate percussion both sides' quality, speed and other related factors by the driver, roughly estimate the collision energy level, regulate the earial drainage resistance in view of the above, when estimating that the percussion energy is big,, turns down greatly resistance otherwise being transferred.More than estimation adjusts that can be realized by electronic system (computer) more can be accurately rapid.The outer thick stick that the appearance of its outer thick stick can make pedestrian or driver notice to stretch out with eye-catching color or mark is with the anti-collision people.Finish this effect with outer thick stick indicator lamp evening.The electric wire distributor 23 that indicator lamp is arranged on the framework is hung the ring electric wire by a dragline string and is being constituted, and can regain electric wire in the time of emitting electric wire, retraction when outer thick stick stretches out and make its unlikely mopping floor.
Major advantage of the present invention is exactly that safe effect is reliable, its buffer action produces by seven aspects are collaborative, and effect, the gas of giving birth to heat as the effect of the preceding soft thick stick that has described in detail, the effect that is transformed into air bellow potential energy, pressure gas push through the rubbing effect of effect, piston and the buffering casing wall of drain passageway frictional heat, the elastic reaction of piston itself, the effect of assistant cylinder displacement.Both made wherein several effects malfunctioning, available buffer is gone back in remaining effect, adding the host buffer system communicates with auxiliary safety device, both made the driver can not control vehicle, and still can start safety air bag, brake gear, fuel oil multiviscosisty device automatically and send the collision alarm automatically with near the attentions such as people's car reminding in when collision.Another advantage of the present invention is to use conveniently, for example the front and back framework all can be reached long span when running on expressway, and the downtown area many people, that the car slow train is few can shorten to interposition or full reduced time, change little curved, also can full reduced time at parking area or when putting in storage.Easy to adjust, for a long time during the piston wear bad sealing, only the screw thread that need tighten between pilot bar and the piston rod gets final product clamping piston, makes its sealing that radially swells intact then, but several times of life-savings like this, and need not tear open greatly.The present invention is suitable for being installed on the automobile of various tack horizontal tails most, is preferably in the car front and back and all pacifies.And the present invention is applied widely, can be used for various landway traffic tools, also is applicable to boats and ships, aerocraft, the empty multiple purpose aeroplane animal in water route, not only is suitable for the civilian warplane animal that also is suitable for.Make soft thick stick 1 the most handy foamed polyurethane of the present invention and answer polyvinylchloride outward, the peace socket is stayed at the place at the both sides indicator lamp, the fwd non-metallic part 2 the most handy glass-felt plastics of hard thick stick, metal part 3 usefulness aluminum alloys or general steel, piston rod 4 requires to have enough resistance to bendings, pilot bar can be used general steel with back thick stick 8, piston rod 4 is threaded with pilot bar 7 usefulness, can adjust folder power whereby to piston 5, piston 5 the most handy rubber are made, the casing wall of assistant cylinder 9 is thickeied gradually to the inner, and tube chamber also will diminish gradually, to improve the comformability to distribution of pressure.The cross sectional shape of assistant cylinder 9 is so that be installed as, and for example chassis side rail is a channel-section steel, and assistant cylinder 9 is just made the class square-section.Pipeline is preferably selected the rubber wire high-pressure pipe for use.The retraction of framework can use same source of the gas with releasing, and uses with releasing similar anti-process and makes its retraction, also can pullback spring be installed on framework, mentions control and sells 24 and open eduction valve 17 frameworks and just be pulled.In order to strengthen buffering effect, can keep pressure apparatus automatically in order to keep this pressure to adopt to the inner chamber pressurization of assistant cylinder 9, connect a pressoreceptor as inner chamber at assistant cylinder, when pressure is lower than requirement, sends signal and open pressure charging valve automatically with supplementary pressure.
