Referring to fig. 1-2, a vehicle wheel side inflation and deflation system 1 is provided in accordance with one embodiment of the present utility model. The vehicle wheel side inflation and deflation system 1 comprises an integrated valve 11, an inflator pump 12 and an air storage tank 13, wherein a first air passage and a second air passage are arranged in the integrated valve 11; the inflator 12 is in communication with the first gas path; the air storage tank 13 is communicated with the second air channel; the inflator 12 inflates the tires of the vehicle via the first air path and/or the air tank 13 inflates the tires of the vehicle via the second air path.
In the vehicle wheel rim inflation and deflation system provided by the embodiment of the utility model, when the tire of the vehicle needs to be inflated, the air storage tank 13 can be selected as an air source for inflation, and the air storage tank 13 is used for inflating the tire through the second air path.
The use of the air reservoir 13 as a source of inflation air has the following advantages:
the air storage tank can realize higher pressure, and the pressure is higher than the pressure of the air charging pump, so that quick air charging can be realized. For example, a conventional air storage tank can store air with the volume of 8L and the pressure of more than 17Bar, and compared with the inflation pump for inflating the tire, the air storage tank can meet the requirement of rapid inflation of the tire. And the capacity of the air storage tank can be flexibly adjusted according to the actual condition of the vehicle. Alternatively, the capacity of the air tank 13 is not less than 8L.
In addition, when the requirement of the inflation amount of the tire is large, the inflator 12 can also inflate the tire through the first air passage, so that the aim of synchronously inflating the tire and pressurizing is fulfilled. And when one of the inflator pump 12 and the air storage tank 13 fails or one of the first air passage and the second air passage fails, the other air passage and the corresponding air passage can be adopted to inflate the tire, so that the vehicle wheel side inflation and deflation system has higher reliability.
Referring to fig. 1-2, in one embodiment, a central air passage is provided in the integrated valve 11, and an inflation valve 111 is integrally provided in the integrated valve 11; the first air passage is communicated with the central air passage; the inflation valve 111 is disposed in the second air path, and the second air path is communicated with the central air path when the inflation valve 111 is opened; the tires of the vehicle are connected to the central air passage via tire air paths.
In this particular example, the first air path in which the inflator 12 is located is directly connected to the central air path, and the first air path is communicated or blocked from the central air path by the switch of the inflator 12 itself. The second air passage where the air storage tank 13 is located is provided with an air charging valve 111, and when the air charging valve 111 is opened, the second air passage is communicated with the central air passage; when the inflation valve 111 is closed, the second air path is blocked from the central air path. The tire is connected with the central air passage through the tire air passage, when the air storage tank 13 is adopted for inflating the tire, the inflation valve 111 is opened, and air enters the tire through the second air passage, the central air passage and the tire air passage after coming out of the air storage tank.
It will be appreciated that the four tires of the vehicle are each connected to the central air duct via one tire air path; that is, the front left tire is connected to the central air duct via the front left tire air duct, the front right tire is connected to the central air duct via the front right tire air duct, the rear left tire is connected to the central air duct via the rear left tire air duct, and the rear right tire is connected to the central air duct via the rear right tire air duct.

Further, in the case that the pressure of the air tank 13 is less than the pressure threshold, the inflation valve 111 is opened and the inflator 12 inflates the air tank 13 via the first air path, the central air path, and the second air path.
In this particular example, the air pressure sensor 112, which is integrally provided in the integrated valve 11 and communicates with the central air passage, may be used not only to monitor the actual pressure of each tire of the vehicle, but also to monitor the pressure inside the air tank 13. When the pressure in the air storage tank 13 is insufficient, the system can automatically control the inflator pump 12 and the inflation valve 111 to be opened for inflating the air storage tank 13; when the pressure in the air storage tank 13 reaches the pressure threshold value, the air pump 12 is closed, so that the air pressure in the air storage tank 13 is maintained, and the requirement of rapid air charging is met.
Referring to fig. 1-2, in one embodiment, a first air release valve 113 is integrally disposed in the integrated valve 11, and a third air passage is disposed in the integrated valve 11, the third air passage is connected to the central air passage, and the first air release valve 113 is disposed in the third air passage;
the primary air release valve 113 is configured to: with the first deflation valve 113 open, the tire is deflated via the tire air path, the central air path, the third air path, and the first deflation valve 113.
In this particular example, the first deflation valve 113 integrally provided within the integration valve 11 may be implemented to deflate the tire.
More specifically, referring to fig. 2, in one embodiment, four control valves 114 are integrally provided in the integrated valve 11, each tire is correspondingly connected to one of the control valves 114, and each tire is provided with a rim valve 14;
for either tire: when the first air release valve 113, the control valve 114, and the rim valve 14 are opened, the tire is deflated via the tire air passage, the center air passage, the third air passage, and the first air release valve 113.
In this specific example, for any tire for which a deflation operation is to be performed, the control valve 114 and the rim valve 14 corresponding to the tire are opened, and the first deflation valve 113 is opened at the same time, and the air in the tire is discharged to the atmosphere through the tire air passage, the control valve 114, the central air passage, the third air passage, and the first deflation valve 113 corresponding to the tire, thereby realizing deflation of the tire.
It will be appreciated that one end of the primary air bleed valve 113 is connected to the central air passage via a third air passage, and the other end of the primary air bleed valve 113 is open to the external atmosphere.
Referring to fig. 1-2, in one embodiment, the integrated valve 11 is integrally provided with a second air release valve 115, and the integrated valve 11 is provided with a fourth air passage, the fourth air passage is connected to the central air passage, and the second air release valve 115 is disposed in the fourth air passage;
the secondary bleed valve 115 is configured to: with the second air release valve 115 opened, the air in the tire air path is discharged through the fourth air path and the second air release valve 115 to perform a pressure maintaining action on the tire.
In this specific example, the second air release valve 115 integrally provided in the integrated valve 11 may be implemented to pressurize the tire. Specifically, the wheel side valve 14 belongs to a pneumatic control mechanical valve, a spring is arranged in the pneumatic control mechanical valve, and when the gas pressure is enough to overcome the elasticity of the spring, the wheel side valve is opened; the rim valve closes when the gas pressure is insufficient to overcome the spring force. When the pressure maintaining action is required to be executed, the second air release valve 115 is opened, the air in the tire air path is discharged to the atmosphere through the central air path, the fourth air path and the second air release valve 115, and the air pressure in the tire air path is reduced, so that the wheel edge valve 14 is closed, and the purpose of maintaining the pressure of the tire is achieved. It should be noted that, the deflation rate of the second deflation valve 115 is greater than that of the first deflation valve 113, so that the air pressure in the tire air path can be quickly released, and the pressure maintaining is more accurate.
More specifically, referring to fig. 2, in one embodiment, four control valves 114 are integrally provided in the integrated valve 11, each tire is correspondingly connected to one of the control valves 114, and each tire is provided with a rim valve 14;
for either tire: when both the secondary air release valve 115 and the control valve 114 are opened, the tire is subjected to a pressure maintaining operation so that the rim valve 14 is switched from an open state to a closed state.
In this specific example, for any one tire for which a pressure maintaining operation is required, the control valve 114 corresponding to that tire is kept in an open state while the second air release valve 115 is opened, and initially the rim valve 14 corresponding to that tire is in an open state; the air in the air passage corresponding to the tire is discharged to the atmosphere through the control valve 114, the central air passage, the fourth air passage and the second air release valve 115, and the air pressure in the air passage of the tire is reduced, so that the wheel side valve 14 is closed, and the purpose of maintaining the pressure of the tire is achieved.
It will be appreciated that one end of the secondary bleed valve 115 is connected to the central air passage via a fourth air passage, and the other end of the secondary bleed valve 115 is vented to the external atmosphere.
In addition, a rotary sealing air chamber is connected in the tire air path of any tire.
Referring to fig. 1, in one embodiment, the vehicle wheel side inflation and deflation system includes an electronic control unit 15, the electronic control unit 15 being electrically connected to the integrated valve 11 and sending control signals to the integrated valve 11.
In this specific example, the electronic control unit 15 (ECU) controls the opening and closing of the integrated valve 11 and the inflator 12 through commands issued by a whole-vehicle CAN (controller area network) network. It can be understood that, because the integrated valve 11 is integrally provided with the air charging valve 111, the first air discharging valve 113, the four control valves 114 and the second air discharging valve 115, the electronic control unit 15 controls the opening and closing of the integrated valve 11, that is, the electronic control unit 15 can respectively control the opening and closing of the air charging valve 111, the first air discharging valve 113, the four control valves 114 and the second air discharging valve 115, and can perform combined control on the air charging valve 111, the first air discharging valve 113, the four control valves 114 and the second air discharging valve 115.
In addition, the electronic control unit 15 can automatically control the combination of the air pump 12, the air storage tank 13 and the integrated valve 11, and the single tire or the combined tire is inflated and deflated and subjected to pressure maintaining and pressure measuring operation, so that the comfort and the driving experience of the vehicle are improved. The vehicle wheel rim inflation and deflation system is powered by a whole vehicle distribution box to provide 12V power supply. The ECU is communicated with the vehicle-mounted system through the CAN bus, so that the operation intention of a driver CAN be obtained; and, the ECU is connected with a TPMS (tire pressure monitoring system 16) which can send a tire pressure signal to the ECU so that the ECU acquires the actual tire pressure of each tire, and rapidly transmits data to the ECU when the tire pressure is suddenly changed, and the ECU control system performs an inflation or deflation operation in combination with the input information of the driver on the multimedia screen.
