[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on December 26, 2023, with application number 202311833114.X and titled “Fluid Control Module, Air Suspension System and Vehicle,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0003] The present disclosure relates to the field of vehicle technology, and in particular, to a fluid control module, an air suspension system, and a vehicle. Background Art

[0004] In related technologies, atmospheric air passes through components such as the intake valve and air compressor, where it is compressed into high-pressure gas, inflating the air springs of the vehicle's air suspension system. During exhaust, the high-pressure gas in the air springs is exhausted through components such as the return valve. These air suspension systems have long air paths (both intake and exhaust) and numerous components, resulting in a low level of integration and a large space requirement.

[0072] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0073] In the present disclosure, unless otherwise stated, the directions or positional relationships indicated by directional words such as "up", "down", "left", and "right" are defined based on the drawing directions shown in the corresponding drawings. They are only for the convenience of describing the present disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific direction, and a specific directional structure and operation. Therefore, they cannot be understood as limitations on the present disclosure. The terms "inside" and "outside" refer to the inside and outside of the corresponding structural outline.

For details, please refer to the directions shown in Figures 1, 2, and 3.

[0074] In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0075] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0076] As mentioned above, in the relevant technology, multiple valves (such as intake valves, return valves, exhaust valves, etc.) are required in the air suspension system to realize the inflation and exhaust of the air suspension system. The air suspension system has a long air path, many components, and the air suspension system occupies a large space.

[0077] In view of this, as shown in Figures 1 to 10, the first aspect of the present disclosure provides a fluid control module 100, including a module body 1, the module body 1 is provided with an inlet 11, a first opening 13, a second opening 14 and at least one channel 20, wherein the first opening 13 is suitable for being connected to a first device 200 using fluid, the inlet 11 is connected to the first opening 13 through the channel 20 (such as the first channel 111 and the second channel 131 among the multiple channels 20 below), the inlet 11 is connected to the second opening 14 through the channel 20 (such as the first channel 111 and the third channel 141 among the multiple channels 20 below), the second opening 14 is connected to the first opening 13 through the channel 20 (such as the second channel 131 and the third channel 141 among the multiple channels 20 below), and the second opening 14 is suitable for being connected to a fluid recovery device 300 so that the fluid recovery device 300 can recover fluid from the first device 200.

[0078] In the fluid control module 100 provided by the present disclosure, since the above-mentioned inlet 11, the first opening 13, the second opening 14 and the channel 20 that can connect the inlet 11, the first opening 13 and the second opening 14 are provided, the fluid can be provided to the first device 200 by using the flow path formed by the inlet, the corresponding channel 20 and the first opening. When necessary, the fluid recovery device 300 can use the flow path formed by the first opening, the corresponding channel 20 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 device 200 through the fluid control module 100, or can flow to other devices that need to use the fluid. In this way, the fluid control module 100 provided by the present disclosure can achieve fluid recycling, thereby reducing fluid consumption.

[0079] When the fluid control module 100 is applied to the air suspension system 2000 of the vehicle 1000, the inlet 11 of the fluid control module 100 can be connected to an air supply device (e.g., a drying tank 203), the first opening 13 of the fluid control module 100 can be connected to the air spring 2001 and / or the air storage tank in the air suspension system 2000, and the second opening 14 of the fluid control module 100 can be connected to the fluid recovery device 300 on the vehicle 1000. In this way, when the inlet 11 and the first opening 13 of the fluid control module 100 are connected, the air suspension system 2000 can be inflated, and when the first opening 13 and the second opening 14 of the fluid control module 100 are connected, the air in the air suspension system 2000 can be recovered.

[0080] Compared with the solution in the related art that the air suspension system needs to adopt multiple valves, the fluid control module 100 disclosed in the present invention adopts an integrated design, which can realize the inflation, exhaust and gas recovery of the air suspension system 2000 without the use of multiple intake valves, return valves, exhaust valves and other structures. It is beneficial to shorten the air path of the air suspension system 2000, reduce the number of parts, simplify the structure of the air suspension system 2000, improve the compactness and integration of the air suspension system 2000, and can effectively save the space occupied by the air suspension system 2000 and improve the space utilization of the vehicle 1000.

[0081] It should be noted here that the present disclosure does not limit the object to which the fluid control module 100 can be applied. It can be any device suitable for adopting the fluid control module 100. For example, the fluid control module 100 can be applied to an air suspension system 2000, a hydraulic system, an air-conditioning system, and a water circulation system, etc. For example, the fluid control module 100 can be applied to the air suspension system 2000 of a vehicle 1000, and the first device 200 can be an air spring 2001 of the air suspension system 2000.

[0082] In addition, it is understandable that the fluid control module 100 provided in the present disclosure can be applied to not only the vehicle 1000 but also other equipment that needs to control the flow direction of the fluid, and the present disclosure does not limit this.

[0083] Here, the present disclosure does not limit the specific structure of the module 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 body 1 can be connected through the channel 20. As an embodiment of the present disclosure, as shown in Figures 2, 4 to 6, the module body 1 is also provided with a first valve cavity 16, at least one channel 20 includes a first channel 111, a second channel 131 and a third channel 141, the inlet 11 is connected to the first valve cavity 16 through the first channel 111, the first opening 13 is connected to the first valve cavity 16 through the second channel 131, and the second opening 14 is connected to the first valve cavity 16 through the third channel 141. In other words, the inlet 11, the first opening 13 and the second opening 14 are connected to the first valve chamber 16 through the first channel 111, the second channel 131 and the third channel 141 respectively. 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, realizing the inflation, exhaust and gas recovery of the air suspension system 2000.

[0084] Specifically, if the air suspension system 2000 needs to be inflated, the inlet 11 and the first opening 13 can be connected, so that the gas from the external air supply equipment flows from the inlet 11 through the first channel 111 into the first valve chamber 16, and flows into the air bag and / or air tank of the air suspension system 2000 through the first valve chamber 16, the second channel 131 and the first opening 13, thereby realizing the inflation of the air suspension system 2000.

[0085] If the gas of the air suspension system 2000 needs to be recovered, the first opening 13 and the second opening 14 can be connected so that the gas in the air spring 2001 and / or the air tank of the air suspension system 2000 can flow from the first opening 13 through the second channel 131 into the first valve cavity 16, and flow into the fluid recovery device 300 through the first valve cavity 16, the third channel 141 and the second opening 14.

[0086] In the fluid control module 100 disclosed herein, the first channel 111, the second channel 131 and the third channel 141 can all be connected to the first valve chamber 16, and a portion of the first channel 111, the second channel 131 and the third channel 141 constitutes a portion of the first valve chamber 16, which is conducive to the lightweight of the fluid control module 100 and facilitates 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 may also be connected to the first valve chamber 16 through different flow channels, respectively, which is not limited in the present disclosure.

[0088] Optionally, as shown in Figures 1, 2, and 6, the module body 1 is further provided with an outlet 12, and the at least one channel 20 of the fluid control module 100 further includes a fourth channel 121, and the first opening 13 is connected to the outlet 12 in a switchable manner via the fourth channel 121. Since the inlet 11, the first opening 13, the second opening 14, and the outlet 12 in the fluid control module 100 are all connected to 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 through the second channel 131 into the first valve cavity 16, and then flow into the fluid recovery device 300 through the first valve cavity 16, the third channel 141, and the second opening 14, thereby realizing the recovery of the fluid in the first device 200. 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 through the second channel 131 into the first valve chamber 16, and flow into the external environment through the first valve chamber 16, the fourth channel 121 and the outlet 12, thereby realizing the discharge of the fluid in the first device 200, and 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 2000 of the vehicle 1000, in order to avoid the recovery of gas in the air suspension system 2000, part of the high-pressure gas in the air suspension system 2000 will be discharged into the external environment through the inlet 11 and / or the outlet 12, and the air in the air suspension system 2000 will be lost, resulting in less gas being recovered by the fluid recovery device 300.

[0090] Optionally, the fluid control module 100 has a first operating mode, in which the first opening 13 is connected to the second opening 14, and the first opening 13 is not connected to either the inlet 11 or the outlet 12. Thus, 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 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. The fluid in the first device 200 cannot be discharged from the inlet 11 and / or outlet 12 into the external environment.

[0091] For example, when the fluid control module 100 is applied to the air suspension system 2000 of the vehicle 1000, when part of the high-pressure gas of the air suspension system 2000 is recovered, the gas in the air suspension system 2000 can only flow from the first opening 13 through the second channel 131 into the first valve chamber 16, and flow into the fluid recovery device 300 through the first valve chamber 16, the third channel 141 and the second opening 14. The air in the air suspension system 2000 cannot be discharged from the inlet 11 and / or the outlet 12 to the external environment.

[0092] Similarly, the fluid control module 100 also has a second operating mode. In the second operating mode, the first opening 13 is connected to the outlet 12, and the first opening 13 is not connected to the inlet 11 or 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 from the first opening 13 through the second channel 131 into the first valve chamber 16, and then be discharged to 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 to the external environment through the inlet 11 or flow into the fluid recovery device 300 through the second opening 14.

[0093] For example, when the fluid control module 100 is applied to the air suspension system 2000 of the vehicle 1000, when the residual low-pressure gas in the air suspension system 2000 is discharged, the gas in the air suspension system 2000 can only flow into the first valve cavity 16 from the first opening 13 through the second channel 131, and be discharged to the external environment through the first valve cavity 16, the fourth channel 121 and the outlet 12. The air in the air suspension system 2000 cannot be discharged to 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 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 insufficient fluid flowing into the first device 200 and insufficient fluid replenishment in the first device 200, thereby affecting the normal use of the first device 200, the fluid control module 100 optionally has a third operating mode. In the third operating mode, the inlet 11 is connected to the first opening 13, and the inlet 11 is not connected to the outlet 12 or the second opening 14.

[0095] In this way, when the first device 200 replenishes the fluid, the fluid in the external environment can only flow from the inlet 11 into the first valve chamber 16 through the first channel 111, 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 from the outlet 12 to the external environment.

[0096] For example, when the fluid control module 100 is applied to the air suspension system 2000 of the vehicle 1000, when the air suspension system 2000 is inflated, the air in the external environment can only flow from the inlet 11 through the first channel 111 into the first valve chamber 16, and flow into the air bag and / or air tank of the air suspension system 2000 through the first valve chamber 16, the second channel 131 and the first opening 13, thereby realizing the inflation of the air suspension system 2000. The air in the external environment cannot flow into the fluid recovery device 300 from the second opening 14, or be discharged from the outlet 12 to the external environment.

[0097] To prevent gas in the fluid recovery device 300 from flowing from the second opening 14 through the second channel 131 into the first valve chamber 16, and then flowing through the first valve chamber 16 to the first opening 13, the inlet 11, and the outlet 12, thereby causing gas leakage in the fluid recovery device 300, the third channel 141 is optionally configured as a one-way channel. Within the third channel 141, 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 from the fluid recovery device 300 back into the first valve chamber 16.

[0098] For example, when the fluid control module 100 is applied to the air suspension system 2000 of the vehicle 1000, the air in the air suspension system 2000 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] In order to form the third channel 141 into a one-way channel, optionally, as shown in Figures 1, 2 and 7, the fluid control module 100 further includes a first one-way valve 5, which is arranged in the third channel 141 to form the third channel 141 into a one-way channel.

[0100] Similarly, to prevent gas from leaking from the inlet 11 of the fluid control module 100, the first channel 111 can optionally be configured as a one-way channel, in which fluid is adapted to flow from the inlet 11 to the first valve chamber 16. In this way, fluid can only flow from the external environment through the first channel 111 into the first valve chamber 16, 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 2000 of the vehicle 1000 , the gas in the air suspension system 2000 can only flow from the external environment into the first valve cavity 16 through the first channel 111 , but cannot flow from the first valve cavity 16 into the external environment.

[0102] In order to form the first channel 111 into a one-way channel, optionally, as shown in Figures 2, 3 and 7, the fluid control module 100 further includes a second one-way valve 6, which is arranged in the first channel 111 to configure the first channel 111 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 installed in the third channel 141 and the first channel 111 respectively, and the third channel 141 and the first channel 111 can form a one-way channel. As an embodiment of the present disclosure, as shown in Figure 7, the first one-way valve 5 and the second one-way valve 6 each include a valve body 51, a valve disc 52, a spring 53, a limit ring 54 and a third sealing ring 55. The limit ring 54 is installed on the valve disc 52, and the valve disc 52 is movably installed on the valve body 51. The valve body 51 is located between the limit ring 54 and the valve disc 52. The third sealing ring 55 is used to be arranged between the valve body 51 and the valve disc 52 to seal the gap between the valve body 51 and the valve disc 52. The spring 53 is sleeved on the valve body 51 and is used to apply an elastic force to the valve body 51 to cause it to move toward the valve disc 52. In this way, when the fluid control module 100 is applied to the air suspension system 2000 of the vehicle 1000, when the air suspension system 2000 is inflated, the air pressure of the external environment is greater than the pressure of the air in the first channel 111, and the valve body 51 moves toward the direction close to the limit ring 54 under the action of the air pressure. At this time, the air can flow into the first channel 111 from the opening on the valve body 51, and flow into the air suspension system 2000 through the first channel 111 and the first valve chamber 16.

[0104] Moreover, when the air suspension system 2000 is not inflated, the valve body 51 can press 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 chamber 16 to the side close to the inlet 11.

[0105] In addition, if the pressure of the air in the first channel 111 is greater than the air pressure of the external environment, the valve body 51 will further press 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 better 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 relative to the third channel 141 and the second one-way valve 6 relative to the first channel 111, the module body 1 may optionally further include a third sealing ring 55, as shown in FIG2 . The two third sealing rings 55 are respectively disposed in the first channel 111 and the third channel 141, and the third sealing rings 55 are sleeved on the valve body 51. By disposing the third sealing rings 55 in the first channel 111 and the third channel 141, with one end of the third sealing ring 55 abutting against the valve body 51 and the other end of the third sealing ring 55 abutting against the inner wall of the first channel 111 or the third channel 141, the third sealing rings 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 preventing gas leakage 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 shown in Figures 2 and 3, the module body 1 is further provided with a second valve chamber 17, which is connected to the outlet 12 via a fourth channel 121. The second valve chamber 17 is connected to the first valve chamber 16 via a valve port 15. The fluid control module 100 further includes a valve core assembly 3 and an actuator 4. The actuator 4 is used to drive the valve core assembly 3 to move within the valve port 15 to achieve communication or disconnection between the first valve chamber 16 and the second valve chamber 17. In this way, when the first device 200 replenishes fluid or recovers fluid, the actuator 4 can drive the valve core assembly 3 to move within the valve port 15 between the first valve chamber 16 and the second valve chamber 17, so that the valve core assembly 3 can seal the valve port 15, and the fluid flowing through the first valve chamber 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 2000 of the vehicle 1000, when the air suspension system 2000 is inflated or the gas is recovered, the actuator 4 can drive the valve core assembly 3 to move in the valve port 15 between the first valve chamber 16 and the second valve chamber 17, so that the valve core assembly 3 can seal the valve port 15, and the air flowing through the first valve chamber 16 cannot flow from the valve port 15 to the outlet 12.

[0109] In addition, when the gas in the air suspension system 2000 needs to be discharged, the actuator 4 can also drive the valve core assembly 3 to move, so that the valve core assembly 3 and the valve port 15 are out of contact, thereby opening the valve port 15 and discharging the gas through the valve port 15, the second valve chamber 17, the fourth channel 121 and the outlet 12.

[0110] The present disclosure does not limit the specific structure of the actuator 4 and the valve core assembly 3. It is sufficient that the valve core assembly 3 can open or close the valve port 15 under the action of the actuator 4, thereby connecting or disconnecting the first valve chamber 16 from the second valve chamber 17. As one embodiment of the present disclosure, as shown in Figures 8 and 9, the actuator 4 includes a coil 43, a frame 44, a plug 45, and a housing 47. The coil 43 is mounted on the housing 47 via the frame 44, and the plug 45 is connected to the coil 43. The valve core assembly 3 includes a valve core 31, an iron core 32, and a magnetic isolation tube 33. The iron core 32 is connected to the valve core 31, and the magnetic isolation tube 33 is sleeved around the iron core 32, with the iron core 32 being 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 valve core 31 to move, thereby connecting or disconnecting the first valve chamber 16 from the second valve chamber 17.

[0111] The present disclosure does not limit the installation method of the actuator 4 and the valve core assembly 3 on the module body 1. To facilitate installation of the actuator 4 and the valve core assembly 3 on the module body 1, as one embodiment of the present disclosure, as shown in FIG2 , a first mounting hole 18 is defined in the module body 1, and a second mounting hole 42 is defined in the actuator 4. A first fastener 41 can pass through the second mounting hole 42 and connect with the first mounting hole 18. The actuator 4 and the valve core assembly 3 are securely fixed to the module body 1, effectively preventing the actuator 4 and / or the valve core assembly 3 from shaking on the module body 1, which could result in the valve port 15 not being tightly closed and causing fluid leakage.

[0112] Optionally, as shown in Figures 1, 2 and 3, the fluid control module 100 also includes a pressure sensor 7, which is used to detect the pressure at the second opening 14. The actuator 4 is configured to drive the valve core assembly 3 to move in the valve port 15 based on the detection result of the pressure sensor 7 to achieve communication or disconnection between the first valve chamber 16 and the second valve chamber 17. In this way, when the fluid control module 100 is applied to the air suspension system 2000 of the vehicle 1000, when the air in the air suspension system 2000 is discharged, the valve core assembly 3 closes the valve port 15, and part of the gas in the air suspension system 2000 (i.e., the high-pressure gas mentioned above) flows from the first opening 13 through the second channel 131 into the first valve chamber 16, and flows into the fluid recovery device 300 through the first valve chamber 16, the third channel 141 and the second opening 14. 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 valve core assembly 3 to move and open the valve port 15, so that when the residual low-pressure gas in the air suspension system 2000 is discharged, the gas flows from the first opening 13 through the second channel 131 into the first valve chamber 16, and is discharged to the external environment through the first valve chamber 16, the fourth channel 121 and the outlet 12.

[0113] The present disclosure does not limit the positional relationship between the inlet 11 and the second opening 14. Optionally, as shown in Figures 1 to 4, the inlet 11 is arranged on the first side 21 of the module body 1 in the first direction, and the second opening 14 is arranged on the side of the module body 1 in the second direction, and the second direction intersects with the first direction. Since the inlet 11 and the second opening 14 are staggered on the module body 1, the distance between the inlet 11 and the second opening 14 is large. The inlet 11 can be directly connected to the external environment or connected to the external environment through other components. The second opening 14 can also be connected to the fluid recovery device 300, which effectively avoids 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 embodiments in which the fluid control module 100 includes an outlet 12, optionally, as shown in Figures 4 to 5, the inlet 11 is located on a first side 21 of the module body 1 in a first direction, the outlet 12 and the first opening 13 are both located on a second side 22 of the module body 1 in the first direction, with the second side 22 opposing the first side 21, and the second opening 14 is located on a side of the module body 1 in a second direction, where the second direction intersects the first direction. The inlet 11, outlet 12, first opening 13, and second opening 14 are located at different positions on the module body 1, and no mechanical interference occurs between the inlet 11, outlet 12, first opening 13, second opening 14, and components connected to the inlet 11, outlet 12, first opening 13, and second opening 14.

[0115] To facilitate connection of any one or more of the inlet 11, outlet 12, first opening 13, and second opening 14 to the external environment or other components, any one or more of the inlet 11, outlet 12, first opening 13, and second opening 14 may optionally be configured as quick-connect connectors. This simplifies the connection of the fluid control module 100 to the external environment or other components, thereby improving the efficiency of the connection between the fluid control module 100 and the external environment and / or other components.

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

[0117] According to the second aspect of the present disclosure, an air suspension system 2000 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 the 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 2000 is inflated, the air flows from the inlet 11 through the first channel 111 into the first valve cavity 16, and flows into the air spring 2001 through the first valve cavity 16, the second channel 131 and the first opening 13, thereby realizing the inflation of the air suspension system 2000.

[0119] When the air suspension system 2000 is exhausted, part of the high-pressure gas is first recovered through the fluid recovery device 300. At this time, the gas in the air bag and / or the gas tank of the air suspension system 2000 flows from the first opening 13 through the second channel 131 into the first valve chamber 16, and flows into the fluid recovery device 300 through the first valve chamber 16, the third channel 141 and the second opening 14, thereby realizing the exhaust gas collection of the air suspension system 2000.

[0120] After the gas collection of the air suspension system 2000 is completed, the gas in the airbag and / or gas tank of the air suspension system 2000 flows from the first opening 13 through the second channel 131 into the first valve chamber 16, and flows into the external environment through the valve port 15, the second valve chamber 17, the fourth channel 121 and the outlet 12, thereby completing the exhaust of the air suspension system 2000.

[0121] The air suspension system 2000 has all the beneficial effects of the above-mentioned fluid control module 100 , which will not be described in detail here.

[0122] The present disclosure does not limit the specific structure of the air suspension system 2000. As one embodiment of the present disclosure, the air suspension system 2000 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 air in the external environment into high-pressure gas and provide it to the air spring 2001, thereby inflating the air spring 2001.

[0123] At the same time, the first switch valve 202 can realize the connection or cutoff between the air compressor 201 and the air spring 2001. In this way, when the air spring 2001 is inflated, the first switch 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 is exhausted, the first switch valve 202 can also connect the flow path between the air compressor 201 and the air spring 2001, thereby discharging the air in the air spring 2001.

[0124] Optionally, as shown in FIG10 , the air suspension system 2000 may further include a drying tank 203, one end of which is adapted to be connected to the air compressor 201, and the other end of which 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 shown in FIG10 , the air suspension system 2000 may further include a second on-off valve 204 and a first air storage tank 205, the outlet 12 of the air compressor 201 is further adapted to be connected to the first air storage tank 205 via the second on-off valve 204, and the first on-off valve 202 and the second on-off 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 2000 is inflated, the air can be filled into the air spring 2001 and also rushed into the first air tank 205. In this way, when the air suspension system 2000 is in use, when the air spring 2001 needs to be inflated, the air spring 2001 can be directly inflated through the air compressor 201, or the air spring 2001 can be directly inflated through the air stored in the first air tank 205 without starting the air compressor 201, which is beneficial to improving the inflation efficiency of the air spring 2001.

[0125] To facilitate exhaust of the air suspension system 2000, the air suspension system 2000 optionally further includes a pressure relief valve 206, as shown in FIG10 . 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. Thus, when the air spring 2001 and / or the first air storage tank 205 are exhausted, air flows into the first valve chamber 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. This effectively prevents the high-pressure gas in the air spring 2001 and / or the first air storage tank 205 from damaging the air compressor 201 when the air suspension system 2000 is exhausted.

[0126] According to a third aspect of the present disclosure, a vehicle 1000 is provided, comprising the air suspension system 2000 as described above, or comprising the fluid control module 100 as described above.

[0127] The vehicle 1000 has all the beneficial effects of the air suspension system 2000 or the fluid control module 100 , which will not be described in detail here.

[0128] Here, the present disclosure does not limit the equipment in the vehicle 1000. Optionally, as shown in Figure 7, the vehicle 1000 includes a second device 303 using fluid, and the fluid recovery device 300 is connected to the second device 303 so that the fluid recovery device 300 can replenish fluid to the first device 200 and / or the second device 303.

[0129] The present disclosure does not limit the first device 200 and the second device 303 that utilize fluid; they may be any device suitable for use with the fluid control module 100. For example, the first device 200 may be an air spring 2001 in an air suspension system 2000, and the second device 303 may include an airbag 3031 disposed within the vehicle 1000. In this way, air from the air suspension system 2000 can flow to the airbag 3031 through the fluid recovery device 300, eliminating the need for a separate inflation device for the airbag 3031.

[0130] Optionally, the airbag 3031 is provided on the seat side of the cab of the vehicle 1000. In this way, the airbag 3031 on the seat side of the cab of the vehicle 1000 does not need a separate inflation module. Instead, the air in the air suspension system 2000 can be inflated into the airbag 3031 on the seat side of the cab of the vehicle 1000 via the fluid control module 100, thereby saving the cost of using the airbag 3031 on the seat side of the cab of the vehicle 1000.

[0131] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within 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 fall within the scope of protection of the present disclosure.

[0132] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0133] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
