In the integrated valve assembly provided by the embodiment of the utility model, the tire control valve 11 and the pressure maintaining valve 13 are integrally arranged in the integrated valve body 10. Controlling inflation of the vehicle tires by opening and closing the respective valves; specifically, in the case where the external air source is turned on, inflation of the tires of the vehicle is controlled by opening the tire control valve 11.

When the tire of the vehicle is inflated to a set pressure value, the external air source is closed, and then the pressure maintaining valve 13 is immediately opened to exhaust the air in the tire air path so as to reach the atmospheric pressure value.

The integrated valve assembly provided by the embodiment of the utility model integrates the tire control valve 11 and the pressure maintaining valve 13 on the integrated valve body 10, and has compact structure and higher integration level. The integrated valve assembly can be installed to realize the inflation and pressure maintaining operation of the tire of the vehicle, so that higher installation and operation efficiency and good driving performance are achieved.

Further, the tire control valve 11 includes a first control valve 111, a second control valve 112, a third control valve 113, and a fourth control valve 114; wherein the first control valve 111 acts on the rear right tire; the second control valve 112 acts on the rear left tire, the third control valve 113 acts on the front left tire, and the fourth control valve 114 acts on the front right tire.

In one embodiment, the integrated valve assembly further comprises a bleed valve 12, the bleed valve 12 being disposed in the integrated valve body 10, and the bleed valve 12 being in communication with the central air passage, the tire control valve 11 being further configured to: for deflating the tire in cooperation with the deflate valve 12.

When the tire is required to be deflated, in the case where the external air source is closed, the tire of the vehicle is controlled to be deflated by opening the tire control valve 11 and the deflation valve 12, and when the deflation reaches the set value, the deflation valve 12 is closed to stop the tire deflation. By integrating the purge valve 12 in the integrated valve assembly, the integration level of the integrated valve assembly is further improved.

Referring to FIG. 1, in one embodiment, the integrated valve body 10 has a first surface 101; the valve port of the tire control valve 11, the valve port of the purge valve 12, and the valve port of the pressure maintaining valve 13 are all provided on the first surface 101 and exposed to the outside of the integrated valve body 10.

In this specific example, the valve ports of the tire control valve 11, the air release valve 12 and the pressure maintaining valve 13 are all arranged on the same surface of the integrated valve body 10, namely, the first surface 101, so that the integrated valve assembly has higher integration level and is more convenient to use.

In one embodiment, a tire air channel, a deflation air channel and a pressure maintaining air channel are arranged in the integrated valve body 10, and the tire air channel, the deflation air channel and the pressure maintaining air channel are all connected to the central air channel; the tire control valve 11 is communicated with the central air passage through the tire air passage, the air release valve 12 is communicated with the central air passage through the air release air passage, and the pressure maintaining valve 13 is communicated with the central air passage through the pressure maintaining air passage. And, one end of the said air release valve 12 is communicated to the said air release gas circuit, another end is communicated to the atmosphere; one end of the pressure maintaining valve 13 is communicated with the pressure maintaining gas path, and the other end is communicated with the atmosphere.

In this particular example, a plurality of air passages are provided in the integrated valve body 10; namely a tire air passage, a deflation air passage and a pressure maintaining air passage, and the air passages are communicated to the central air passage, so that the operations of inflating, deflating and pressure maintaining for the tires of the vehicle are realized.

For example, when the tire is inflated, the tire control valve 11 is opened, and air is introduced from an external air source into the tire air path via the central air passage to inflate the tire. When the tire is deflated, the tire control valve 11 and the deflation valve 12 are opened, and the air in the tire enters the deflation air passage through the tire air passage and the central air passage and finally enters the atmosphere. When the tire is subjected to pressure maintaining operation, the tire control valve 11 and the pressure maintaining valve 13 are opened, and the gas in the tire gas path enters the pressure maintaining gas path through the central gas path and finally enters the atmosphere.

Referring to fig. 1, in one embodiment, the integrated valve body 10 has a second surface 102, the second surface 102 being disposed adjacent to the first surface 101; the integrated valve assembly further comprises a connector 14 and a circuit board 15, the circuit board 15 is arranged inside the integrated valve body 10, one end of the connector 14 is connected with the circuit board 15, the other end of the connector 14 is arranged on the second surface 102 and exposed outside the integrated valve body 10, and the other end of the connector 14 is used for connecting an electric control element.

In this particular example, the connector 14 disposed on the second surface 102 of the integrated valve body 10 is configured to couple to an electrical control element to provide electrical control of the integrated valve assembly.

In one embodiment, the purge valve 12 has a first port and the pressure maintaining valve 13 has a second port, and the aperture of the first port is smaller than the aperture of the second port.

In this specific example, the aperture of the valve port of the purge valve 12 is set smaller than the aperture of the valve port of the pressure maintaining valve 13, so that the purge speed of the purge valve 12 is made smaller than the purge speed of the pressure maintaining valve 13. Therefore, the purge valve 12 is also called a slow release valve, and the pressure maintaining valve 13 is also called a fast release valve.

Referring to fig. 3, in one embodiment, the air release valve 12 includes a valve body 121, a spring 122, and a switch block 123, the first valve port is opened in the valve body 121, the spring 122 is disposed in the valve body 121, and a bottom surface of the switch block 123 abuts against the spring 122.

In this particular example, the operation principle of the air release valve 12 is a problem of balancing the pressure difference between the two ends of the air inlet and the air outlet of the air release valve 12 with the elastic force of the spring 122. As described above, the air inlet end of the air release valve 12 is communicated with the air release air path, and the air outlet end is communicated to the atmosphere; when the pressure difference between the air release path and the atmosphere is larger than the elastic force of the spring 122, the switch block 123 opens the valve body 121, i.e. the air release valve 12 is opened and air release is performed; when the pressure difference between the air release path and the atmosphere is smaller than the elastic force of the spring 122, the switch block 123 closes the valve body 121, i.e., the air release valve 12 closes and stops the air release.

Alternatively, the deflation speed of the deflation valve 12 may be increased by unscrewing the switch block 123 by providing the switch block 123 in threaded connection with the valve body 121; the deflation speed of the deflation valve 12 is reduced by tightening the switch block 123. In addition, the adjustment of the deflation speed of the deflation valve 12 can also be achieved by changing different springs 122.

Referring to fig. 1, in one embodiment, the integrated valve assembly further includes a gas tank pipe 16, one end of the gas tank pipe 16 is connected to the central gas passage, the other end of the gas tank pipe 16 is disposed on the first surface 101 and exposed to the outside of the integrated valve body 10, and the other end of the gas tank pipe 16 is used for connection with a gas tank source of an external gas source.

In this particular example, inflation of the tire by the air reservoir air supply is accomplished by providing an air reservoir conduit 16. The air storage tank air source has the advantages that the use frequency of the air compressor can be reduced, the service life of the air compressor is prolonged, and the air storage tank air source has the characteristics of high air charging speed and high air charging efficiency. Thus, when only a single tire needs to be inflated, or when the amount of inflation is relatively small although multiple tires need to be inflated, the air reservoir air source may be used to inflate.

Referring to fig. 1, in one embodiment, the integrated valve assembly further includes an air source pipe 17, one end of the air source pipe 17 is connected to the central air passage, the other end of the air source pipe 17 is disposed on the first surface 101 and exposed to the outside of the integrated valve body 10, and the other end of the air source pipe 17 is used for air source connection with an inflator in an external air source.

In this particular example, inflation of the tire by an inflator source may be accomplished through source line 17. For example, when all four tires need to be inflated and the inflation demand is large, an inflator gas source is opened, and gas enters the tires to inflate the tires through the gas source pipeline 17, the central gas passage and the tire gas passage.

Referring to fig. 1, in one embodiment, the integrated valve body 10 is provided with an ear hole 100, and the integrated valve assembly is mounted to a body of a vehicle by a fastener penetrating through the ear hole 100.

In this particular example, the integrated valve assembly can be conveniently mounted on the body of a vehicle by providing the earhole 100 in the integrated valve body 10.

Referring to fig. 2, in one embodiment, a pressure sensor 18 is disposed within the integrated valve body 10, the pressure sensor 18 being in communication with the central air passage, the pressure sensor 18 being configured for monitoring the pressure of a tire of a vehicle.

In this particular example, by providing the pressure sensor 18, the tire pressure and the pressure of each air path can be monitored in real time.

In addition, the pin ends of the pressure sensor 18 and the connector 14 are welded on the circuit board 15, and the pressure sensor 18 and the circuit board 15 are fixed inside the integrated valve body 10 by pouring electronic pouring sealant.

Referring to fig. 1, in one embodiment, the tire control valve 11 is a normally closed solenoid valve.

Referring to fig. 2, in a specific example, the tire control valve 11 is a normally closed electromagnetic valve, which includes a valve element 103 and a solenoid 104, and the solenoid 104 provides magnetic induction force to the valve element 103; with the solenoid 104 energized, the valve spool 103 opens; in the event that the solenoid 104 is de-energized, the valve spool 103 closes. A valve core piston is connected in the valve core 103 through a spring; when the electromagnetic coil 104 is electrified, the magnetic induction force generated on the valve core 103 is larger than the thrust of the spring, so that the valve core piston is opened, namely the electromagnetic valve is opened; when the electromagnetic coil 104 is de-energized, the magnetic force is lost, and the valve core inner spring pushes the valve core piston to close the electromagnetic valve.
