The specific embodiment
Below in conjunction with example, the present invention will be described in detail.
Sealing system for vehicle door provided by the invention, when after closing of the door, operates gas-filled switching tube on request, both can realize the automatic positiver sealing of all car doors, and simple to operate, convenient, sealing property is reliable.
The present invention utilizes the form of gas-flow closure to seal, both there is larger deformation-compensated amount, there is again larger thrust simultaneously, when sealing, utilize integrated control valve body to inner inflatable, sealing band 7 inflations are heaved, and because gas has flowing power in seal chamber, the position that therefore can guarantee each different gaps value can both have same sealing thrust, and thrust can reach designing requirement.The sealing compensation amount of sealing band 7 is large, sealing thrust is even, be particularly suitable for larger (for example command van under mine in car door gap, car door is welded-steel plate construction, car door gap is generally not less than 5mm, and can make because of distortion in use for some time gap become large) vehicle use, simple to operate, volume is little, lightweight.
Vehicle door edge inflatable seal system, comprises integrated control valve body, sealing band 7, air pipe 13; Integrated control valve body comprises by pass valve 1, inflation electromagnetic valve 2, pressure release electromagnetic valve 3 and valve plate 4, by pass valve 1, inflation electromagnetic valve 2, pressure release electromagnetic valve 3 are fixed on valve plate 4, as shown in the structural representation of Fig. 1 integrated control valve, at the other pressure release electromagnetic valve 3 of separately establishing of inflation electromagnetic valve 2, pressure release electromagnetic valve 3 one end connect sealing band 7, and the other end directly communicates with atmosphere.
Integrated control valve body is a limit air inflator system " air circuit breaker ", by inflation, pressurize, the pressure leak process of integrated control valve body control gate limit gas-flow closure bar.Integrated control valve body one end is by by pass valve 1, valve plate 4 and air pipe 13 are connected with the gas cylinder 8 of vehicle, the other end is connected with door limit gas-flow closure bar 7 by inflation electromagnetic valve 2 and air pipe 13, during inflation, gas-filled switching tube is placed in to " inflation " gear, inflation electromagnetic valve 2 is opened, source of the gas is provided by mounted gas cylinder 8, gas in gaholder 8 with the storage pressure in gas cylinder by the admission port by pass valve 1 of flowing through, by by pass valve 1, change the flow pressure of gas, with the pressure of setting, flow out by pass valve 1, enter inflation electromagnetic valve 2, now, inflation electromagnetic valve 2 is opened, pressure release electromagnetic valve 3 is closed, the air pipe 13 that gas flows to door limit gas-flow closure bar 7 by inflation electromagnetic valve 2 flows into door limit gas-flow closure bar 7,
When the inflation pressure of door limit gas-flow closure bar 7 reaches setting value, gas-filled switching tube is placed in " keep;; gear; inflation electromagnetic valve 2 and pressure release electromagnetic valve 3 Close Alls, the gas of door gas-flow closure bar 7 inside, limit keeps current pressure to be sealed in integrated control valve body in the gas circuit of door limit gas-flow closure bar 7 cavity insides;
While no longer needing door sealing, door limit switch is placed in to " pressure release " gear, inflation electromagnetic valve 2 is closed (gas of door limit gas-flow closure bar no longer communicates with the gas in gas cylinder), pressure release electromagnetic valve 3 is opened, pressure release electromagnetic valve 3 directly communicates with atmosphere, now, because gas-flow closure bar 7 interior gas atmosphere in door limit are higher than bar pressure, therefore gas is directly released in atmosphere and goes through pressure release electromagnetic valve 3, and concrete principle as shown in Figure 2,3.
Switch is provided with " inflation ", " pressurize ", " pressure release " three gears altogether, and 2 energisings of " inflation " gear control inflation electromagnetic valve are opened, and pressure release electromagnetic valve 3 power-off are closed; " pressurize " gear control inflation electromagnetic valve 2 and the interior equal no current of pressure release electromagnetic valve 3 pass through, and in closed condition, 3 energisings of " pressure release " gear control pressure release electromagnetic valve are opened, and 2 power-off of inflation electromagnetic valve are closed.
In accompanying drawing 4,5 provided by the invention, integrated control valve has 7 interfaces, respectively that 1 admission port 9, one air extractor duct that leads to atmosphere, 5 lead to a gas injection port for limit sealing band, described gas cylinder 8 is connected with by pass valve 1, inflation electromagnetic valve 2 by air pipe 13, adaptor union, admission port 9, then being divided into 5 tunnel gas circuits connects respectively 5 by air pipe 13, adaptor union and leads to a gas injection port for limit sealing band 7, if the car door of vehicle is less than 5, can utilize plug screw to block one of them or several gas injection port; Door limit sealing band 7 is connected with the interface of integrated control valve by air pipe 13, adaptor union, and the air extractor duct that leads to atmosphere of the integrated control valve pressure release electromagnetic valve 3 of connecting, has a road gas circuit of one's own, for pressure release; Inflation electromagnetic valve 2, pressure release electromagnetic valve 3 are connected with gas-filled switching tube by cable respectively, by energising unlatching and the power-off of 2 electromagnetic valves of gas-filled switching tube control, are closed.
During inflation, gas-filled switching tube is placed in to " inflation " gear, gas-filled switching tube is placed in to " maintenance " gear after 5～8s, complete gas replenishment process, now car door is in sealing state; During pressure release, gas-filled switching tube is placed in to " pressure release " gear, gas-filled switching tube is placed in to " maintenance " gear after 5～8s, complete pressure leak process, now car door is in non-tight state.
According to specific exemplary embodiment, invention has been described herein.It will be apparent under not departing from the scope of the present invention, carrying out to one skilled in the art suitable replacement or revise.Exemplary embodiment is only illustrative, rather than the restriction to scope of the present invention, and scope of the present invention is defined by appended claim.
