Detailed Embodiment

[0071] The following details the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure and are not intended to limit the present disclosure.

[0072] In the present disclosure, unless otherwise stated, the orientation terms such as "upper", "lower", "left", "right", etc. indicate the orientation or position relationship defined based on the drawing direction shown in the corresponding drawings. They are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation of the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour. In the drawings and the text, the "first direction" generally refers to the left - right direction relative to the contour of the fluid control module itself, and the "second direction" generally refers to the front - back direction relative to the contour of the fluid control module itself. For specific reference, please refer to Figure 1 、 Figure 2 and Figure 3 the directions shown.

[0073] In addition, it should be noted that terms such as "first" and "second" are used to distinguish one element from another, and do not have an order or importance. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0074] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "connected", "linked", and "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0075] As mentioned above, in the related art, multiple valves (such as an intake valve, a return air valve, an exhaust valve, etc.) are required in an air suspension system to achieve inflation and exhaust of the air suspension system. The air path of the air suspension system is long, there are many components, and the space occupied by the air suspension system is large.

[0076] In view of this, as Figures 1 to 10 shown, in the first aspect of the present disclosure, a fluid control module 100 is provided, which includes a module main body 1. The module main body 1 is provided with an inlet 11, a first opening 13, a second opening 14, and at least one channel. Among them, the first opening 13 is adapted to be connected to a first device 200 that uses fluid. The inlet 11 is connected to the first opening 13 through the channel, the inlet 11 is connected to the second opening 14 through the channel, the second opening 14 is connected to the first opening 13 through the channel, and the second opening 14 is adapted to be connected to a fluid recovery device 300 so that the fluid recovery device 300 can recover the fluid from the first device 200.

[0077] In the fluid control module provided by the present disclosure, due to the provision of the above-mentioned inlet 11, first opening 13, second opening 14, and channels that can connect the inlet 11, first opening 13, and second opening 14.

[0078] The flow path formed by connecting the inlet, the corresponding channel, and the first opening can be used to supply fluid to the first device 200. When needed, the fluid recovery device 300 can use the flow path formed by connecting the first opening, the corresponding channel, and the second opening to recover the fluid from the first device 200. The fluid recovered by the fluid recovery device 300 can flow back to the first fluid device through the fluid control module again, or flow to other devices that need to use fluid. In this way, through the fluid control module 100 provided by the present disclosure, the recycling of fluid can be realized, thereby reducing fluid consumption.

[0079] When the fluid control module 100 is applied to the air suspension system of a vehicle, the inlet 11 of the fluid control module 100 can be connected to a gas supply device (such as a drying tank 203), the first opening 13 of the fluid control module 100 can be connected to an air spring 2001 and / or an air storage tank in the air suspension system, and the second opening 14 of the fluid control module 100 can be connected to a fluid recovery device 300 on the vehicle. In this way, when the inlet 11 and the first opening 13 of the fluid control module 100 are connected, inflation of the air suspension system can be achieved; when the first opening 13 and the second opening 14 of the fluid control module 100 are connected, recovery of the gas in the air suspension system can be achieved.

[0080] Compared with the solution in the related art where multiple valves are required for the air suspension system, the fluid control module 100 of the present disclosure adopts an integrated design. Without using multiple inlet valves, return air valves, exhaust valves and other structures, inflation, exhaust and gas recovery of the air suspension system can be achieved, which is beneficial to shortening the air path of the air suspension system, reducing the number of components, simplifying the structure of the air suspension system, improving the compactness and integration degree of the air suspension system, effectively saving the space occupied by the air suspension system, and improving the space utilization rate of the vehicle.

[0081] Here, it should be noted that the present disclosure does not limit the object to which the fluid control module 100 is applied. It can be any device suitable for using the fluid control module 100. For example, the fluid control module 100 can be applied to an air suspension system, a hydraulic system, an air conditioning system, a water circulation system, etc. For example, the fluid control module can be applied to the air suspension system of a vehicle, and the first device 200 can be an air spring of the air suspension system.

[0082] In addition, it can be understood that the object to which the fluid control module 100 provided by the present disclosure is applied can be other than a vehicle, and can also be applied to other devices that need to control the fluid flow direction. The present disclosure does not limit this.

[0083] Here, the present disclosure does not limit the specific structure of the module main body 1, as long as any one or more of the inlet 11, the first opening 13, and the second opening 14 of the module main body 1 can be connected through a channel. As an implementation manner of the present disclosure, such as Figure 2 、 Figures 4 to 6As shown, the module body 1 is further provided with a first valve chamber 16. At least one channel includes a first channel 111, a second channel 131, and a third channel 141. The inlet 11 is connected to the first valve chamber 16 through the first channel 111. The first opening 13 is connected to the first valve chamber 16 through the second channel 131. The second opening 14 is connected to the first valve chamber 16 through the third channel 141. In other words, the inlet 11, the first opening 13, and the second opening 14 are respectively connected to the first valve chamber 16 through the first channel 111, the second channel 131, and the third channel 141. By reasonably controlling the opening and closing of the inlet 11, the first opening 13, and the second opening 14 in the module body 1, the fluid control module 100 can have different working modes. For example, it can realize the inflation, exhaust, and gas recovery of the air suspension system.

[0084] Specifically, if it is necessary to inflate the air suspension system, the inlet 11 and the first opening 13 can be connected, so that the gas from the external gas supply device flows from the inlet 11 through the first channel 111 into the first valve chamber 16, and then through the first valve chamber 16, the second channel 131, and the first opening 13 into the airbag and / or gas storage tank of the air suspension system, thereby realizing the inflation of the air suspension system.

[0085] If it is necessary to recover the gas of the air suspension system, the first opening 13 and the second opening 14 can be connected, so that the gas in the air spring and / or gas storage tank of the air suspension system can flow from the first opening 13 through the second channel 131 into the first valve chamber 16, and then through the first valve chamber 16, the third channel 141, and the second opening 14 into the fluid recovery device 300.

[0086] In the fluid control module 100 of the present disclosure, the first channel 111, the second channel 131, and the third channel 141 can all be connected to the first valve chamber 16. A part of the first channel 111, the second channel 131, and the third channel 141 constitutes a part of the first valve chamber 16. This is beneficial to the lightweight of the fluid control module 100 and is also convenient for the processing of the fluid control module 100.

[0087] As another embodiment, the first channel 111, the second channel 131, and the third channel 141 can also be respectively connected to the first valve chamber 16 through different flow channels. The present disclosure does not limit this.

[0088] Optionally, as Figure 1 、 Figure 2 and Figure 6As shown, the module body 1 is further provided with an outlet 12. At least one channel of the fluid control module 100 further includes a fourth channel 121. The first opening 13 is communicably connected to the outlet 12 through the fourth channel 121 in a switchable manner. Since the inlet 11, the first opening 13, the second opening 14, and the outlet 12 in the fluid control module 100 are all in communication with the first valve cavity 16, when the fluid in the first device 200 is discharged, the fluid in the first device 200 can first flow from the first opening 13 into the first valve cavity 16 through the second channel 131, and then flow into the fluid recovery device 300 through the first valve cavity 16, the third channel 141, and the second opening 14, so that the recovery of the fluid in the first device can be realized. In addition, when the fluid in the first device 200 is not recovered, the fluid in the first device 200 can also flow from the first opening 13 into the first valve cavity 16 through the second channel 131, and then flow into the external environment through the first valve cavity 16, the fourth channel 121, and the outlet 12, so as to realize the discharge of the fluid in the first device 200. The recovery process and the discharge process of the fluid in the first device 200 do not interfere with each other.

[0089] For example, when the fluid control module 100 is applied to the air suspension system of a vehicle, in order to avoid the situation that when the gas in the air suspension system is recovered, some high-pressure gas in the air suspension system is discharged to the external environment through the inlet 11 and / or the outlet 12, resulting in the loss of air in the air suspension system and less gas recovered by the fluid recovery device 300.

[0090] Optionally, the fluid control module 100 has a first working mode. In the first working mode, the first opening 13 is in communication with the second opening 14, and the first opening 13 is not in communication with the inlet 11 and the outlet 12. In this way, when the fluid in the first device 200 is recovered, the fluid in the first device 200 can only flow from the first opening 13 into the first valve cavity 16 through the second channel 131, and then flow into the fluid recovery device 300 through the first valve cavity 16, the third channel 141, and the second opening 14. The fluid in the first device 200 cannot be discharged to the external environment through the inlet 11 and / or the outlet 12.

[0091] For example, when the fluid control module 100 is applied to the air suspension system of a vehicle, when some high-pressure gas in the air suspension system is recovered, the gas in the air suspension system can only flow from the first opening 13 into the first valve cavity 16 through the second channel 131, and then flow into the fluid recovery device 300 through the first valve cavity 16, the third channel 141, and the second opening 14. The air in the air suspension system cannot be discharged to the external environment through the inlet 11 and / or the outlet 12.

[0092] Similarly, the fluid control module 100 further has a second working mode. In the second working mode, the first opening 13 communicates with the outlet 12, and the first opening 13 does not communicate with the inlet 11 and the second opening 14. In this way, when the fluid in the first device 200 is discharged, the fluid in the first device 200 can only flow into the first valve chamber 16 through the second channel 131 from the first opening 13, and is discharged into the external environment through the first valve chamber 16, the fourth channel 121, and the outlet 12. The fluid in the first device 200 cannot be discharged into the external environment from the inlet 11, or flow into the fluid recovery device 300 from the second opening 14.

[0093] For example, when the fluid control module 100 is applied to the air suspension system of a vehicle, when the residual low-pressure gas in the air suspension system is discharged, the gas in the air suspension system can only flow into the first valve chamber 16 through the second channel 131 from the first opening 13, and is discharged into the external environment through the first valve chamber 16, the fourth channel 121, and the outlet 12. The air in the air suspension system cannot be discharged into the external environment from the inlet 11, or flow into the fluid recovery device 300 from the second opening 14.

[0094] Furthermore, in order to prevent the fluid flowing into the first device 200 from the inlet 11 from flowing into the fluid recovery device 300 through the second opening 14, or being discharged into the external environment through the outlet 12 when the first device 200 is replenished with fluid, resulting in less fluid flowing into the first device 200 and insufficient fluid replenishment of the first device 200, affecting the normal use of the first device 200. Optionally, the fluid control module 100 has a third working mode. In the third working mode, the inlet 11 communicates with the first opening 13, and the inlet 11 does not communicate with the outlet 12 and the second opening 14.

[0095] In this way, when the first device 200 is replenished with fluid, the fluid in the external environment can only flow into the first valve chamber 16 through the first channel 111 from the inlet 11, and flow into the first device 200 through the first valve chamber 16, the second channel 131, and the first opening 13, thereby realizing the fluid replenishment of the first device 200. The fluid in the external environment cannot flow into the fluid recovery device 300 from the second opening 14, or be discharged into the external environment through the outlet 12.

[0096] For example, when the fluid control module 100 is applied to the air suspension system of a vehicle, when the air suspension system is inflated, the air in the external environment can only flow into the first valve chamber 16 through the first channel 111 from the inlet 11, and flow into the airbag and / or air storage tank of the air suspension system through the first valve chamber 16, the second channel 131, and the first opening 13, thereby realizing the inflation of the air suspension system. The air in the external environment cannot flow into the fluid recovery device 300 from the second opening 14, or be discharged into the external environment through the outlet 12.

[0097] To avoid the gas in the fluid recovery device 300 flowing from the second opening 14 into the first valve chamber 16 through the second channel 131 and flowing through the first valve chamber 16 to the first opening 13, the inlet 11, and the outlet 12, resulting in air leakage of the fluid recovery device 300. Optionally, the third channel 141 is set as a one-way channel. In the third channel 141, the fluid is adapted to flow from the first valve chamber 16 to the second opening 14. In this way, the fluid can only flow from the first valve chamber 16 through the third channel 141 to the fluid recovery device 300, and cannot flow back from the fluid recovery device 300 into the first valve chamber 16.

[0098] For example, when the fluid control module 100 is applied to the air suspension system of a vehicle, the air in the air suspension system can only flow from the first valve chamber 16 through the third channel 141 to the fluid recovery device 300, and cannot flow back from the fluid recovery device 300 into the first valve chamber 16.

[0099] To make the third channel 141 form a one-way channel, optionally, as Figure 1 , Figure 2 and Figure 7 shown, the fluid control module 100 further includes a first one-way valve 5, and the first one-way valve 5 is arranged in the third channel 141 to make the third channel 141 configured as a one-way channel.

[0100] Similarly, to avoid the occurrence of gas leakage at the inlet 11 of the fluid control module 100, optionally, the first channel 111 can also be set as a one-way channel. In the first channel 111, the fluid is adapted to flow from the inlet 11 to the first valve chamber 16. In this way, the fluid can only flow from the external environment into the first valve chamber 16 through the first channel 111, and cannot flow from the first valve chamber 16 into the external environment.

[0101] For example, when the fluid control module 100 is applied to the air suspension system of a vehicle, the gas in the air suspension system can only flow from the external environment into the first valve chamber 16 through the first channel 111, and cannot flow from the first valve chamber 16 into the external environment.

[0102] To make the first channel 111 form a one-way channel, optionally, as Figure 2 , Figure 3 and Figure 7 shown, the fluid control module 100 further includes a second one-way valve 6, and the second one-way valve 6 is arranged in the first channel 111 to make the first channel 111 configured as a one-way channel.

[0103] The present disclosure does not limit the specific structures of the first one-way valve 5 and the second one-way valve 6, as long as the first one-way valve 5 and the second one-way valve 6 can be respectively installed in the third channel 141 and the first channel 111, and the third channel 141 and the first channel 111 can form a one-way channel. As an implementation manner of the present disclosure, as Figure 7 shown, both the first one-way valve 5 and the second one-way valve 6 include a valve body 51, a valve plate 52, a spring 53, a limiting ring 54, and a third sealing ring 55. The limiting ring 54 is installed on the valve plate 52, the valve plate 52 is movably installed in the valve body 51, the valve body 51 is located between the limiting ring 54 and the valve plate 52, and the third sealing ring 55 is used to be arranged between the valve body 51 and the valve plate 52 to seal the gap between the valve body 51 and the valve plate 52. The spring 53 is sleeved on the valve body 51, and the spring 53 is used to apply an elastic force to the valve body 51 to make it move towards the valve plate 52. Thus, when the fluid control module 100 is applied to the air suspension system of a vehicle and the air suspension system is inflated, the air pressure in the external environment is greater than the air pressure in the first channel 111. The valve body 51 moves towards the direction close to the limiting ring 54 under the action of the air pressure. At this time, air can flow into the first channel 111 from the opening on the valve body 51 and flow into the air suspension system through the first channel 111 and the first valve cavity 16.

[0104] Moreover, when the air suspension system is not inflated, the valve body 51 can abut against the valve plate 52 under the action of the elastic force of the spring 53, and clamp the third sealing ring 55 between the valve body 51 and the valve plate 52. The valve plate 52 and the third sealing ring 55 can jointly seal the opening on the valve body 51, and air will not flow from the side of the first one-way valve 5 and / or the second one-way valve 6 close to the first valve cavity 16 to the side close to the inlet 11.

[0105] In addition, if the air pressure in the first channel 111 is greater than the air pressure in the external environment, the valve body 51 will further abut against the valve plate 52 under the action of the internal and external pressure difference, and the valve body 51 will not separate from the valve plate 52 under the action of the pressure in the first channel 111. The first one-way valve 5 and the second one-way valve 6 have good sealing performance for the third channel 141 and the first channel 111.

[0106] To further improve the sealing performance of the first one-way valve 5 for the third channel 141 and the second one-way valve 6 for the first channel 111, optionally, as Figure 2As shown, the module body 1 may further include a third sealing ring 55. The two third sealing rings 55 are respectively used to be arranged in the first channel 111 and the third channel 141, and the third sealing ring 55 is sleeved on the valve body 51. By arranging the third sealing ring 55 in the first channel 111 and the third channel 141, and one end of the third sealing ring 55 abuts against the valve body 51, and the other end of the third sealing ring 55 abuts against the inner wall of the first channel 111 or the third channel 141, the third sealing ring 55 can seal the gaps between the first one-way valve 5 and the third channel 141, and between the second one-way valve 6 and the first channel 111, effectively avoiding the leakage of gas from the gaps between the first one-way valve 5 and the third channel 141, and between the second one-way valve 6 and the first channel 111.

[0107] Optionally, as Figure 2 and Figure 3 shown, the module body 1 is further provided with a second valve cavity 17. The second valve cavity 17 is communicated with the outlet 12 through a fourth channel 121. The second valve cavity 17 is connected to the first valve cavity 16 through a valve port 15. The fluid control module 100 further includes a valve core 31 assembly 3 and an actuator 4. The actuator 4 is used to drive the valve core 31 assembly 3 to move in the valve port 15 to realize the communication or cut-off between the first valve cavity 16 and the second valve cavity 17. In this way, when the first device 200 replenishes fluid or fluid is recovered, the actuator 4 can drive the valve core 31 assembly 3 to move in the valve port 15 between the first valve cavity 16 and the second valve cavity 17, so that the valve core 31 assembly 3 can seal the valve port 15, and the fluid flowing through the first valve cavity 16 cannot flow from the valve port 15 to the outlet 12.

[0108] For example, when the fluid control module 100 is applied to the air suspension system of a vehicle, when the air suspension system is inflated or gas is recovered, the actuator 4 can drive the valve core 31 assembly 3 to move in the valve port 15 between the first valve cavity 16 and the second valve cavity 17, so that the valve core 31 assembly 3 can seal the valve port 15, and the air flowing through the first valve cavity 16 cannot flow from the valve port 15 to the outlet 12.

[0109] In addition, when the gas in the air suspension system needs to be discharged, the actuator 4 can also drive the valve core 31 assembly 3 to move, so that the valve core 31 assembly 3 is disengaged from the valve port 15, thereby opening the valve port 15, and discharging through the valve port 15, the second valve cavity 17, the fourth channel 121 and the outlet 12.

[0110] Here, the present disclosure does not limit the specific structures of the actuator 4 and the valve core 31 assembly 3, as long as the valve core 31 assembly 3 can open or close the valve port 15 under the action of the actuator 4 to realize the communication or cut-off between the first valve cavity 16 and the second valve cavity 17. As an embodiment of the present disclosure, as Figure 8 and Figure 9As shown, the actuator 4 includes a coil 43, a bobbin 44, a plug 45, and a housing 47. The coil 43 is mounted on the housing 47 through the bobbin 44, and the plug 45 is connected to the coil 43. The spool 31 assembly 3 includes a spool 31, an iron core 32, and a magnetic isolation tube 33. The iron core 32 is connected to the spool 31, and the magnetic isolation tube 33 is sleeved on the iron core 32. The iron core 32 can be at least partially exposed from the magnetic isolation tube 33. The coil 43 of the actuator can generate an induced magnetic field under the action of an electric current, causing the iron core 32 to move under the action of the induced magnetic field, thereby driving the spool 31 to move, and realizing the connection or cutoff between the first valve cavity 16 and the second valve cavity 17.

[0111] The present disclosure does not limit the installation method of the actuator 4 and the spool 31 assembly 3 on the module body 1. For the convenience of installing the actuator 4 and the spool 31 assembly 3 on the module body 1, as an embodiment of the present disclosure, as Figure 2 shown, a first mounting hole 18 is formed on the module body 1, and a second mounting hole 42 is formed on the actuator 4. The first fastener 41 can pass through the second mounting hole 42 and be connected to the first mounting hole 18. The actuator 4 and the spool 31 assembly 3 are fixedly reliable on the module body 1, effectively avoiding the situation that the actuator 4 and / or the spool 31 assembly 3 shake on the module body 1, resulting in the valve port 15 not being tightly closed and fluid leakage.

[0112] Optionally, as Figure 1 、 Figure 2 and Figure 3 shown, the fluid control module 100 further includes a pressure sensor 7. The pressure sensor 7 is used to detect the pressure at the second opening 14. The actuator 4 is configured to drive the spool 31 assembly 3 to move within the valve port 15 based on the detection result of the pressure sensor 7, so as to realize the connection or cutoff between the first valve cavity 16 and the second valve cavity 17. In this way, when the fluid control module 100 is applied to the air suspension system of a vehicle, when the air in the air suspension system is discharged, the spool 31 assembly 3 closes the valve port 15, and part of the gas in the air suspension system (i.e., the high-pressure gas mentioned above) flows from the first opening 13 through the second channel 131 into the first valve cavity 16, and then through the first valve cavity 16, the third channel 141, and the second opening 14 into the fluid recovery device 300. When the pressure sensor 7 detects that the pressure at the second opening 14 is lower than the preset value, the actuator 4 drives the spool 31 assembly 3 to move, opening the valve port 15, so that when the remaining low-pressure gas in the air suspension system is discharged, the gas flows from the first opening 13 through the second channel 131 into the first valve cavity 16, and then through the first valve cavity 16, the fourth channel 121, and the outlet 12 to the external environment.

[0113] The present disclosure does not limit the positional relationship between the inlet 11 and the second opening 14. Optionally, as Figures 1 to 4As shown, the inlet 11 is provided on the first side of the module body 1 in the first direction, and the second opening 14 is provided on one side of the module body 1 in the second direction, where the second direction intersects the first direction. Since the inlet 11 and the second opening 14 are staggered from each other on the module body 1 and the distance between the inlet 11 and the second opening 14 is relatively large, the inlet 11 can be directly connected to the external environment or can be connected to the external environment through other components. The second opening 14 can also be connected to the fluid recovery device 300, effectively avoiding the interference between the fluid recovery device 300 and / or other components respectively connected to the second opening 14 and the inlet 11 due to the small distance between the inlet 11 and the second opening 14, and the situation where the fluid recovery device 300 and / or other components cannot be installed on the inlet 11 and / or the second opening 14.

[0114] For the embodiment in which the fluid control module 100 includes the outlet 12, optionally, as shown in FIGS. to Figure 4 As shown, the inlet 11 is provided on the first side of the module body 1 in the first direction, the outlet 12 and the first opening 13 are both provided on the second side of the module body 1 in the first direction, the second side is opposite to the first side, and the second opening 14 is provided on one side of the module body 1 in the second direction, where the second direction intersects the first direction. The inlet 11, the outlet 12, the first opening 13, and the second opening 14 are respectively provided at different positions on the module body 1, and there will be no mechanical interference between the inlet 11, the outlet 12, the first opening 13, the second opening 14, and the components connected to the inlet 11, the outlet 12, the first opening 13, and the second opening 14.

[0115] To facilitate the connection of any one or more of the inlet 11, the outlet 12, the first opening 13, and the second opening 14 to the external environment or to other components, optionally, any one or more of the inlet 11, the outlet 12, the first opening 13, and the second opening 14 are provided as quick-connect interfaces. The connection between the fluid control module 100 and the external environment or other components is relatively simple, which is beneficial to improving the connection efficiency between the fluid control module 100 and the external environment and / or other components.

[0116] To facilitate the connection of any one or more of the inlet 11, the outlet 12, the first opening 13, and the second opening 14 to the external environment or to other components, optionally, as Figure 1 、 Figure 2 and Figure 3As shown, the fluid control module 100 further includes at least one air nozzle 9, and any one or more of the inlet 11, the outlet 12, the first opening 13, and the second opening 14 are connected to the corresponding air nozzle 9. The air nozzle 9 facilitates the connection of any one or more of the inlet 11, the outlet 12, the first opening 13, and the second opening 14 to the external environment and / or components, thereby improving the connection efficiency between the fluid control module 100 and the external environment and / or other components.

[0117] According to a second aspect of the present disclosure, an air suspension system is provided, including a first device 200, a fluid recovery device 300, and the fluid control module 100 as described above. The first device 200 includes an air spring 2001. The first opening 13 is connected to the air spring 2001, and the second opening 14 is connected to the fluid recovery device 300 so that the fluid recovery device 300 can recover the gas in the air spring 2001.

[0118] Specifically, the inlet 11 of the fluid control module 100 can be connected to the external environment through a drying tank 203, the outlet 12 can be directly connected to the external environment, the first opening 13 is connected to the air spring 2001, and the second opening 14 is connected to the fluid recovery device 300. When the air suspension system is inflated, air flows from the inlet 11 through the first channel 111 into the first valve chamber 16, and through the first valve chamber 16, the second channel 131, and the first opening 13 into the air spring 2001, thereby achieving the inflation of the air suspension system.

[0119] When the air suspension system exhausts, some high-pressure gas is first recovered through the fluid recovery device 300. At this time, the gas in the airbag and / or gas storage tank of the air suspension system flows from the first opening 13 through the second channel 131 into the first valve chamber 16, and through the first valve chamber 16, the third channel 141, and the second opening 14 into the fluid recovery device 300, thereby achieving the waste gas collection of the air suspension system.

[0120] After the gas collection of the air suspension system is completed, the gas in the airbag and / or gas storage tank of the air suspension system flows from the first opening 13 through the second channel 131 into the first valve chamber 16, and through the valve port 15, the second valve chamber 17, the fourth channel 121, and the outlet 12 into the external environment, thereby completing the exhaust of the air suspension system.

[0121] This air suspension system has all the beneficial effects of the above-mentioned fluid control module 100, which will not be elaborated here.

[0122] The present disclosure does not limit the specific composition of the air suspension system. As an implementation manner of the present disclosure, the air suspension system further includes an air compressor 201 and a first switching valve 202. The inlet 11 of the air compressor 201 is connected to the first opening 13, and the outlet 12 of the air compressor 201 is connected to the air spring 2001 through the first switching valve 202. The air compressor 201 can compress the air in the external environment into high-pressure gas and supply it to the air spring 2001, thereby realizing the inflation of the air spring 2001.

[0123] At the same time, the first switching valve 202 can realize the connection or disconnection between the air compressor 201 and the air spring 2001. In this way, when the inflation of the air spring 2001 is completed, the first switching valve 202 can cut off the flow path between the air compressor 201 and the air spring 2001, and the air in the air spring 2001 will not leak from the air compressor 201. When the air spring 2001 exhausts air, the first switching valve 202 can also connect the flow path between the air compressor 201 and the air spring 2001, so as to exhaust the air in the air spring 2001.

[0124] Optionally, as Figure 10 shown, the air suspension system may further include a drying tank 203. One end of the drying tank 203 is adapted to be connected to the air compressor, and the other end of the drying tank 203 is adapted to be connected to the air spring 2001. The drying tank 203 can dry the gas entering the air spring 2001. Optionally, as Figure 10 shown, the air suspension system further includes a second switching valve 204 and a first air storage tank 205. The outlet 12 of the air compressor 201 is also adapted to be connected to the first air storage tank 205 through the second switching valve 204, and the first switching valve 202 and the second switching valve 204 are arranged on the flow path connecting the air spring 2001 and the first air storage tank 205. When the air suspension system is inflated, the air can be both inflated into the air spring 2001 and into the first air storage tank 205. In this way, during the use of the air suspension system, when the air spring 2001 needs to be inflated, it can be directly inflated by the air compressor 201, or the air compressor 201 can be not started, and the air stored in the first air storage tank 205 can be directly used to inflate e, which is beneficial to improving the inflation efficiency of the air spring 2001.

[0125] For the convenience of exhausting air from the air suspension system, optionally, as Figure 10As shown, the air suspension system further includes a pressure relief valve 206. One end of the pressure relief valve 206 is adapted to be connected to the first opening 13, and the other end of the pressure relief valve 206 is adapted to be connected to the air spring 2001. In this way, when the air spring 2001 and / or the first air storage tank 205 exhaust air, the air flows into the first valve cavity 16 through the pressure relief valve 206, the first opening 13, and the second channel 131, and the air does not directly flow through the air compressor 201, effectively avoiding the situation that the high-pressure gas in the air spring 2001 and / or the first air storage tank 205 damages the air compressor 201 when the air suspension system exhausts air. According to the third aspect of the present disclosure, a vehicle is provided, including the air suspension system as described above, or including the fluid control module 100 as described above.

[0126] The vehicle has all the beneficial effects of the above air suspension system or the above fluid control module 100, which will not be elaborated here.

[0127] Here, the present disclosure does not limit the devices in the vehicle. Optionally, as Figure 7 shown, the vehicle includes a second device 303 that uses a fluid, and the fluid recovery device 300 is connected to the second device 303 so that the fluid recovery device 300 can supply the fluid to the first device 200 and / or the second device 303.

[0128] The present disclosure does not limit both the first device 200 and the second device 303 that use the fluid. They can be any devices suitable for adopting the fluid control module 100. For example, the first device 200 can be the air spring 2001 in the air suspension system, and the second device 303 can include an airbag 3031 arranged inside the vehicle. In this way, the air of the air suspension system can flow to the airbag 3031 through the fluid recovery device 300, and the airbag 3031 does not need to be separately designed with an inflation device.

[0129] Optionally, the above airbag 3031 is an airbag 3031 arranged on one side of the seat in the vehicle cab. In this way, the airbag 3031 on one side of the seat in the vehicle cab does not need to be separately designed with an inflation module, and the air in the air suspension system can be filled into the airbag 3031 on one side of the seat in the vehicle cab through the fluid control module 100, which is beneficial to saving the use cost of the airbag 3031 on one side of the seat in the vehicle cab.

[0130] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0131] In addition, it should be noted that, for the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination manners.

[0132] In addition, any combination can be made among the various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
