action of circular arc sealing rubber plug IV6203 cavity gaseous tension, to reach quick opening gas circuit, in the time of vehicle stationary, circular arc sealing rubber plug IV6203 cavity gaseous tension is used for opening gas circuit check valve IV62013, always there is 2 air passage one-way valve IV62013 conducting in any moment, make the arbitrary moment of gas circuit in inflationtime keep gas circuit conducting, make gas can arrive smoothly tire inflation/deflation structure IV63, in the time not needing to inflate, double end air pump quits work, the inside air cavity air pressure of the IV6204 of falling syringe cylinder structure declines, under the retracing spring IV62045 of the IV6204 of falling syringe cylinder structure inside effect, piston I V62042 moves backward, circular arc sealing rubber plug IV6203 is moved backward, thereby circular arc sealing rubber plug IV6203 and flute profile annulus IV62011 are departed from.The retracing spring IV62045 of the IV6204 of falling syringe cylinder structure inside has simultaneously and prevents that the air pressure of the IV6204 of falling syringe cylinder structure inside is excessive, makes sealing rubber plug IV6203 locking flute profile flute profile annulus IV62011.
The tire inflation/deflation structure IV63 of described the 4th gas circuit affiliate comprises a housing IV6301, is fixed on housing IV6301 stepping motor D 4, by gear width, IV6302 is connected in stepping motor D 4output shaft is for the push rod IV6303 of open check valve, be fixed on the left bottom of housing IV6301 air path controlling mechanism venting check valve IV6304, delivery port and the atmosphere of air path controlling mechanism venting check valve IV6304 join, be fixed on housing IV6301 left end for detection of the tyre pressure sensor IV6305 of tire pressure and the check valve IV6306 that bleeds a tire for bleeding a tire, and be positioned at housing middle and upper part for the tire gas transmission check valve IV6309 to tire gas transmission by 3 input 1 output be connected with the valve of wheel tyre with thimble joint IV6307, be fixed on housing IV6301 middle and lower part enters housing IV6301 air path controlling mechanism breather check valve IV6308 for outside gas, entering the 15 channel connector IV62014 that go out with 4 of air chamber formation structure I V62 is connected.When inflation, motor D 4conter clockwise reversion 45 degree, push rod IV6303 backs down air path controlling mechanism breather check valve IV6308 and tire gas transmission check valve IV6309, thereby make gas form mechanism from outside air chamber and enter housing IV6301 through air path controlling mechanism breather check valve IV6308, thereby inflate to wheel through the valve of tire gas transmission check valve IV6309 arrival wheel again, while reaching regulation tire pressure, when inflation finishes, motor D 4get back to reference position, push rod IV6303 resets and gets back to reference position, and air path controlling mechanism breather check valve IV6308 and tire gas transmission check valve IV6309 reset, and inflation gas circuit disconnects, when venting, and motor D 4cw forward 45 is spent, push rod IV6303 backs down air path controlling mechanism venting check valve IV6304 and the check valve IV6306 that bleeds a tire, thereby make the gas of defeated tire be put back into housing by valve, then be put into atmosphere by the air path controlling mechanism check valve IV6304 that exits, air pressure is declined.When air pressure drops to specified value, D 4motor is got back to start bit, and push rod IV6303 resets and gets back to reference position, thereby air path controlling mechanism venting check valve IV6304 and the check valve IV6306 that bleeds a tire reset, thereby the gas circuit that makes to exit disconnects.Housing housing IV6301 is except the check valve IV6304 that exits by air path controlling mechanism can communicate with atmosphere, other positions all seal, 3 input 1 outputs can be the spool of wheel valve toward pressing down with the thimble in thimble joint IV6307, thereby the gas that can make tire is come 3 inputs 1 and is exported with in thimble joint IV6307, thereby can make tyre pressure sensor IV6305 can detect at any time tire pressure, also can facilitate inflation/deflation simultaneously.Air path controlling mechanism venting check valve IV6304, the check valve IV6306 that bleeds a tire, air path controlling mechanism breather check valve IV6308 and tire gas transmission check valve IV6309 are exactly general common check valve on market, can only open from one end, can not oppositely open, therefore be not described in detail here.
In use, by intelligent control system (not being that emphasis of the present invention is not described in detail at this) thus control each branch air path mechanism automobile carried out to automatic tire pressure adjusting, when intelligent system starting, first judge whether it is that system first is moved, if, (these parameters by given some parameters of producer as a reference will to carry out tire pressure parameter preset of various weather and road conditions, set voluntarily according to local situation by driver and crew, also can adopt the default setting of system), if not being, first to judge that four tires on wheel charge and discharge the whether undervoltage warning of battery of mechanism of qi control mechanism, if had, change the battery on corresponding wheel according to warning mark, if battery undervoltage does not occur reports to the police, judge whether manually to repair tire pressure parameter according to weather and road conditions, revise as needed, manual modification tire pressure parameter, if do not needed to revise, enter normal tire pressure and regulate control process.
