DETAILED DESCRIPTION

[0034] 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.

[0035] In this disclosure, unless otherwise indicated, directional terms such as "upstream" and "downstream" are generally defined based on the direction of fluid flow in a flow path. These terms are intended solely to facilitate and simplify the description of this disclosure and are not intended to indicate or imply that the device or component referred to must have a specific orientation, structure, or operation. Therefore, they should not be construed as limitations on this disclosure. "Inside" and "outside" refer to the inside and outside of the corresponding component outlines. Furthermore, the terms "first" and "second," etc., are used to distinguish one element from another and do not convey sequential or significant meanings.

[0036] 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 in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections, and may be directly connected or indirectly connected through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0037] Research has found that connecting an additional pipe between the air suspension system and the seat side wing system to enable an air supply device to supply air to the air suspension system and the seat side wing system will lead to an increasing number of water corrosion inside the air suspension system and ice formation in winter. The main reason is that: since the air suspension system has high requirements for the dryness of the air, an air drying device needs to be installed between the air supply equipment and the air suspension system. The air drying device will gradually become saturated with water and lose its water absorption capacity as it is used. Therefore, the first air supply device is required to backblow a sufficient amount of air to the air drying device to achieve complete dehydration and regeneration of the air drying device and restore its water absorption capacity.

[0038] In the related art, an additional pipe is connected between the air suspension system and the seat wing system, and air is directly supplied to the seat wing system through the air suspension system, which will reduce the amount of air that the air suspension system can use to back-blow the air drying device, so that the air drying device cannot be fully regenerated. Over time, the drying capacity of the air drying device will become lower and lower, resulting in higher and higher humidity of the air flowing into the air suspension system, which will lead to an increase in water corrosion inside the air suspension system and ice formation in winter, causing irreversible damage to the air suspension system.

[0039] In view of this, if Figures 1 to 3 As shown, the present disclosure provides a gas supply module 100, comprising a gas supply device 10 and a gas drying device 20. The inlet of the gas supply device 10 is adapted to communicate with the outside, and the gas drying device 20 is adapted to be connected between the outlet of the gas supply device 10 and a first gas system 200. Furthermore, the gas supply module 100 has a gas backflush mode, wherein in the gas backflush mode, gas from the first gas system 200 can be supplied to the second gas system 300 via the gas drying device 20. The gas drying device 20 can be connected at any position between the first gas system 200 and the second gas system 300.

[0040] Through the above technical solution, the inlet of the gas supply device 10 can be connected to the outside world, and the gas drying device 20 can be connected between the outlet of the gas supply device 10 and the first gas system 200. When the gas supply device 10 is turned on, the gas supply device 10 can transport the outside air to the first gas system 200 through the air drying device. The drying device can absorb the moisture of the air flowing through itself and reduce the humidity of the air transported to the first gas system 200, thereby realizing the gas supply to the first gas system 200 and reducing the adverse effects of moisture in the air on the first gas system 200.

[0041] Moreover, when the second gas system 300 needs to use gas, the gas backflush mode can be turned on so that the gas from the first gas system 200 can be supplied to the second gas system 300 through the gas drying device 20. When the air flows through the gas drying device 20, it can desorb the moisture adsorbed by the gas drying device 20 and take away the desorbed moisture, thereby realizing the regeneration of the gas drying device 20, that is, restoring the gas drying device 20 to a good water absorption capacity.

[0042] Compared with the related art method of connecting an additional pipeline between the air suspension system and the seat wing system and directly supplying air to the seat wing system through the air suspension system, the air supply module 100 provided by the present disclosure can not only meet the air demand of two air systems (i.e., the first air system 200 and the second air system 300) through one gas supply device 10, but also enable the air supplied to the second air system 300 to completely back-blow the gas drying device 20, thereby facilitating that the amount of air back-blown to the gas drying device 20 meets the amount of air required for the regeneration of the gas drying device 20, and further facilitating that the dryness of the air delivered to the first air system 200 (i.e., the air suspension system) is ensured, and the risk of damage to the first air system 200 due to excessive internal air humidity is reduced.

[0043] Furthermore, the gas demand of the second gas system 300 can be utilized to increase the frequency of backflushing the gas drying device 20 , thereby further improving the regeneration effect of the gas drying device 20 and further ensuring the dryness of the gas delivered to the first gas system 200 .

[0044] In addition, since the air of the back-blowing gas drying device 20 may not be discharged to the outside, but is supplied to the second gas system 300 in a closed system, it is beneficial to reduce the workload of the gas supply device 10 and further help reduce energy consumption.

[0045] It should be noted that the "connection" between the two in the present disclosure means that the medium can flow from one of the two to the other. For example, when the inlet of the gas supply device 10 mentioned above is connected to the outside world, the outside air can flow into the gas supply device 10. For another example, when the second opening 22 of the gas drying device 20 mentioned below is connected to the first gas system 200, the gas in the gas drying device 20 can enter the first gas system 200 from the second opening 22, or the gas in the first gas system 200 can enter the gas drying device 20 through the second opening 22.

[0046] It can be understood that the air supply module 100 provided in the present disclosure can be applicable to a variety of first air systems 200 and second air systems 300. For example, since the gas supply device 10 supplies air to the first air system 200, and then the first air system 200 supplies air to the second air system 300, not only can the pressure of the air in the first air system 200 and the second air system 300 be equal, but it can also be easily achieved that the pressure of the air in the second air system 300 is lower than the pressure of the air in the first air system 200. Therefore, the air supply module 100 can be applicable not only to the first air system 200 and the second air system 300 with similar air pressures, but also to the first air system 200 (such as an air suspension system) and the second air system 300 (such as a seat side wing system) with a reduced air pressure gradient.

[0047] Moreover, the pressure of the gas is positively correlated with the humidity. Therefore, when the air supply module 100 is used for the first gas system 200 and the second gas system 300 with a reduced gas pressure gradient, even if the air delivered to the second gas system 300 takes away the moisture in the air drying device during the backblowing process of the air drying device, since the pressure of the air in the second gas system 300 is lower than the pressure of the air in the first gas system 200, the humidity of the air in the second gas system 300 will not increase.

[0048] In addition, the air supply module 100 may also be applicable to a second air system 300 that has a lower requirement on air dryness than the first air system 200 , and this disclosure does not limit this.

[0049] The present disclosure does not limit the type of the gas drying device 20. Optionally, the gas drying device 20 may include a molecular sieve.

[0050] The present disclosure does not limit the structure of the gas drying device 20. As an embodiment, Figure 2 and Figure 3 As shown, the gas drying device 20 has a first opening 21 and a second opening 22 that are connected to each other. The outlet of the gas supply device 10 is suitable for connecting with the first opening 21, and the second opening 22 is suitable for connecting with the first gas system 200. Moreover, the first opening 21 and the second gas system 300 can be selectively connected to enable the gas supply module 100 to have a gas backflush mode.

[0051] In this arrangement, when gas is supplied to the first gas system 200, the first opening 21 and the second gas system 300 are cut off, the gas supply device 10 is opened, and the air output by the gas supply device 10 can flow into the gas drying device 20 from the first opening 21, flow out of the gas drying device 20 from the second opening 22 and flow into the first gas system 200, wherein the gas drying device 20 can dry the air flowing through itself.

[0052] When supplying gas to the second gas system 300, the second opening 22 is connected to the second gas system 300, the gas supply device 10 is closed, and the air of the first gas system 200 can flow into the gas drying device 20 from the second opening 22, flow out of the gas drying device 20 from the first opening 21 and flow into the second gas system 300, wherein the reverse flow through the gas drying device 20 can desorb and take away the moisture absorbed by the gas drying device 20, thereby realizing the regeneration of the gas drying device 20.

[0053] The structure of the gas drying device 20 can achieve the above functions while having the advantages of simple structure and high reliability, and can save pipelines connected thereto, thereby helping to save pipeline costs and reduce the space occupied by pipelines.

[0054] As another embodiment of the present disclosure, the gas drying device 20 may also be configured to have more than two openings to achieve the above functions.

[0055] In order to realize the selective communication between the first opening 21 and the second gas system 300, as an embodiment, Figures 1 to 3 As shown, the air supply module 100 also includes a first valve 31, which can connect the second opening 22 with the first air system 200, and the first valve 31 can also connect the first opening 21 with the second air system 300, or cut off the connection between the first opening 21 and the second air system 300.

[0056] The first valve 31 can be used to flexibly switch the gas supply path according to the gas demand of different gas systems. For example, when supplying gas to the first gas system 200, the first valve 31 can be controlled to cut off the connection between the first opening 21 and the second gas system 300. When supplying gas to the second gas system 300, the first valve 31 can be controlled to connect the first opening 21 with the second gas system 300.

[0057] Furthermore, when there is no need to supply air to the second air system 300 , the first valve 31 can be controlled to cut off at least one-way flow of air from the first air system 200 to the second opening 22 , thereby preventing air in the first air system 200 from leaking outward.

[0058] As another embodiment of the present disclosure, separate on-off valves may be provided between the second opening 22 and the first gas system 200 , and between the first opening 21 and the second gas system 300 , respectively.

[0059] The present disclosure does not limit the structure of the first valve 31. As an embodiment, Figure 2 and Figure 3As shown, the first valve 31 has a valve port A311, a valve port B312, a valve port C313 and a valve port D314, the valve port A311 is used to communicate with the second opening 22, the valve port B312 is used to communicate with the first gas system 200, the valve port C313 is used to communicate with the first opening 21, and the valve port D314 is connected to the second gas system 300, wherein the valve port A311 and the valve port B312 can be selectively connected, and the valve port C313 and the valve port D314 can be selectively connected.

[0060] With such an arrangement, when supplying gas to the first gas system 200, the first valve 31 can be controlled to connect the valve port A311 with the valve port B312 or to connect the valve port A311 to the valve port B312 in one direction, and the valve port C313 and the valve port D314 can be cut off, so that the air from the second opening 22 can flow from the valve port A311 into the first valve 31, and then flow out of the first valve 31 from the valve port B312 and flow to the first gas system 200.

[0061] When supplying gas to the second gas system 300, the first valve 31 can be controlled to connect the valve port A311 with the valve port B312, and to connect the valve port C313 with the valve port D314, so that the air from the first gas system 200 can flow into the first valve 31 from the valve port B312, then flow out of the first valve 31 from the valve port A311, and flow into the first valve 31 from the valve port C313 after flowing through the gas drying device 20 in the opposite direction, and finally flow out of the first valve 31 from the valve port D314 and flow to the second gas system 300.

[0062] As other embodiments of the present disclosure, the first valve 31 may also have more than four or less than four valve ports, and the above functions may be achieved by controlling the communication relationship between different valve ports.

[0063] In order to facilitate the control of the first valve 31, as an embodiment, the first valve 31 has valve position one and valve position two. In valve position one, valve port A311 and valve port B312 are unidirectionally connected in the direction from valve port A311 to valve port B312, and valve port C313 and valve port D314 are cut off. In valve position two, valve port A311 is connected with valve port B312, and valve port C313 is connected with valve port D314, so that the gas supply module 100 has a gas backflush mode.

[0064] In this way, when supplying gas to the first gas system 200, the first valve 31 can be switched to valve position one, so that the air from the gas supply device 10 can pass through the gas drying device 20 and flow to the first gas system 200. When supplying gas to the second gas system 300, the first valve 31 can be switched to valve position two, so that the air from the first gas system 200 can pass through the gas drying device 20 in the opposite direction and flow to the second gas system 300.

[0065] That is to say, the first valve 31 can satisfy at least three functions of supplying gas to the first gas system 200, supplying gas to the second gas system 300, and back-blowing the gas drying device 20 by switching between two valve positions, which is beneficial to reducing the complexity of the structure and action of the first valve 31, and further beneficial to improving the reliability of the first valve 31.

[0066] In addition, since in valve position one, valve port A311 and valve port B312 are unidirectionally connected in the direction from valve port A311 to valve port B312, it is beneficial to prevent the air of the first gas system 200 from flowing back to the gas supply module 100, thereby helping to reduce the leakage of air in the first gas system 200.

[0067] As another embodiment of the present disclosure, the first valve 31 may also have more than two valve positions to achieve the above functions, which is not limited in the present disclosure.

[0068] The present disclosure can drive the first valve 31 to switch the valve position in any suitable manner, and the present disclosure is not limited to this. As an embodiment, Figures 1 to 3 As shown, the air supply module 100 further includes a pilot valve 40 , which is in communication with the first valve 31 and is used to drive the first valve 31 to switch between valve position 1 and valve position 2.

[0069] The action of the pilot valve 40 can be controlled so that the control fluid (such as air) can flow into the actuator of the first valve 31 through the pilot valve 40, thereby driving the first valve 31 to switch between valve position one and valve position two. This hierarchical control method is beneficial for the air supply module 100 to switch the air supply path more smoothly, and is beneficial for avoiding safety hazards such as pressure shock and drastic flow changes caused by sudden valve switching.

[0070] Furthermore, the direct control mechanism (such as a control motor) of the first valve 31 is replaced by the pilot valve 40. Since the pilot valve 40 is small in size and has a simple and compact structure, it is easy to install inside the air supply module 100 without taking up too much space, and is easy to integrate with other valves, pipes and other components, thereby realizing modular design and assembly of complex air supply systems.

[0071] The present disclosure does not limit the specific manner in which the pilot valve 40 drives the first valve 31. As an implementation method, Figure 2 and Figure 3As shown, the first valve 31 includes an air cavity and a valve core movably arranged in the air cavity, and the pilot valve 40 has a valve port E41, a valve port F42 and a valve port G43. The valve port E41 is connected to the first air system 200, the valve port F42 is connected to the air cavity, and the valve port G43 is connected to the valve port D314. The pilot valve 40 has valve position three and valve position four. In valve position three, the valve port F42 is connected to the valve port G43, and the valve port E41 is cut off, so that the valve core can move to a position that switches the first valve 31 to valve position one. In valve position four, the valve port E41 is connected to the valve port F42, and the valve port G43 is cut off, so that the air in the first air system 200 can enter the air cavity to push the valve core and switch the first valve 31 to valve position two.

[0072] With this configuration, when supplying air to the first air system 200, the pilot valve 40 can be controlled to switch to valve position three, i.e., valve port F42 is connected to valve port G43, and valve port E41 is blocked. Since valve port D314 is connected to the second system, valve port G43 can be connected to the outside world or the second air system 300. At this time, the air cavity of the first valve 31 can be connected to the outside world or the second air system 300, and the pressure of the air in the air cavity will not generate a driving force on the valve core, thereby maintaining the first valve 31 in valve position 1. When supplying air to the second air system 300, the pilot valve 40 can be controlled to switch to valve position four, i.e., valve port E41 is connected to valve port F42, and valve port G43 is blocked. At this time, air in the first air system 200 can enter the air cavity, pushing the valve core, and switching the first valve 31 to valve position 2.

[0073] It is understandable that after switching from valve position three to valve position four, the valve core in the air cavity can be reset under the action of gravity or under the action of a reset mechanism (such as a spring), and this disclosure does not limit this.

[0074] Here, the pilot valve 40 may be an electromagnetic pilot valve 40 , and is configured to be maintained at valve position three when power is lost, and to be maintained at valve position four when power is applied.

[0075] As another embodiment of the present disclosure, the valve port E41 may also be connected to other air sources, and the air from other air sources may be used to push the valve core, which is not limited in the present disclosure.

[0076] Alternatively, as Figure 1 As shown, the gas supply module 100 also includes a first flow path 51 and a second valve 32. The second valve 32 is arranged on the first flow path 51 and is used to connect or cut off the first flow path 51. The first end of the first flow path 51 is suitable for communicating with the outside world, and the second end of the first flow path 51 is suitable for communicating with the inlet of the gas supply device 10 and the second gas system 300.

[0077] With such an arrangement, when supplying gas to the first gas system 200, the second valve 32 can be controlled to open the first flow path 51, so that the gas supply device 10 can draw air from the outside through the first flow path 51. When supplying gas to the second gas system 300, the second valve 32 can be controlled to cut off the second flow path 52, so that the air transported by the first gas system 200 to the second gas system 300 will not leak from the first flow path 51 to the outside.

[0078] When the gas drying device 20 needs to be backflushed and the second gas system 300 does not need to be replenished with air, the second valve 32 can be controlled to open the first flow path 51, so that the air from the first gas system 200 can be discharged to the outside from the first flow path 51 after backflushing the gas drying device 20.

[0079] In addition, since the first flow path 51 can be reused in both the intake and exhaust of the air supply module 100, and the first end of the first flow path 51 can be set at any suitable position (such as the bottom of the vehicle), the first flow path 51 can reduce the impact of the intake and exhaust of the air supply module 100 on and the impact of the outside world while saving pipelines.

[0080] Here, the second valve 32 may be an on-off valve, or a regulating valve. The present disclosure does not limit the type of the second valve 32 .

[0081] As another embodiment of the present disclosure, the second end of the first flow path 51 may also be communicated with only the inlet of the gas supply device 10 .

[0082] Alternatively, as Figure 1 As shown, the air supply module 100 further includes a second flow path 52 , a first end of the second flow path 52 being in communication with a second end of the first flow path 51 , and a second end of the second flow path 52 being selectively in communication with the first opening 21 of the gas drying device 20 ; The first opening 21 is communicated with the outlet of the gas supply device 10 , and the first opening 21 is selectively communicated with the second gas system 300 .

[0083] Since the second end of the first flow path 51 is also connected to the second gas system 300 , the air delivered by the first gas system 200 to the second gas system 300 can flow to the second gas system 300 via the second flow path 52 after backflushing the gas drying device 20 .

[0084] Moreover, since the air flow will flow through the second end of the first flow path 51 in various working conditions such as supplying air to the first gas system 200, supplying air to the second gas system 300, and exhausting to the outside after back-blowing the gas drying device 20, the second end of the first flow path 51 has a good reuse rate, which is beneficial to saving the flow path, and further beneficial to reducing the cost and space occupancy of the flow path.

[0085] As another embodiment of the present disclosure, the first end of the second flow path 52 may be directly connected to the second ventilation system.

[0086] Alternatively, as Figure 1 As shown, the air supply module 100 further includes a third flow path 53, a first end of which is connected to the second flow path 52, and a second end of which is connected to the inlet of the gas supply device 10. This arrangement allows external air to flow into the gas supply device 10 via the first flow path 51, a portion of the second flow path 52, and the third flow path 53, thereby increasing the reuse rate of the second flow path 52 and saving the second flow path 52, thereby reducing the cost and space occupied by the flow paths.

[0087] As another embodiment of the present disclosure, the first end of the third flow path 53 may be in communication with the second end of the first flow path 51 .

[0088] Alternatively, as Figure 1 As shown, the air supply module 100 also includes a fourth flow path 54 and a third valve 33. The first end of the fourth flow path 54 is connected to the second end of the first flow path 51, and the first end of the fourth flow path 54 is connected to the first end of the second flow path 52. The second end of the fourth flow path 54 is suitable for connecting to the second gas system 300. The third valve 33 is arranged on the fourth flow path 54 for conducting or cutting off the fourth flow path 54.

[0089] When the gas supply device 10 is turned on, the third valve 33 can be controlled to cut off the fourth flow path 54 to prevent the air in the second gas system 300 from being sucked back by the gas supply device 10. When the first gas system 200 supplies gas to the second gas system 300, the third valve 33 can be controlled to connect the fourth flow path 54 to ensure smooth gas supply from the first gas system 200 to the second gas system 300.

[0090] As another embodiment of the present disclosure, the first end of the fourth flow path 54 may be in communication with the first opening 21 .

[0091] The present disclosure does not limit the type of the third valve 33. As an embodiment, Figure 1 As shown, the third valve 33 is a one-way valve provided on the fourth flow path 54 , and the one-way valve is used to limit the flow direction of the air in the fourth flow path 54 to the direction from the first end of the fourth flow path 54 to the second end of the fourth flow path 54 .

[0092] Since the one-way valve can prevent the air of the second gas system 300 from being sucked away by the opened gas supply device 10, and can also allow the first gas system 200 to supply gas to the second gas system 300, and the one-way valve does not require active control, therefore, setting the third valve 33 as a one-way valve is beneficial to reducing the control complexity of the gas supply module 100 and improving the reliability of the gas supply module 100.

[0093] As another embodiment of the present disclosure, the third valve 33 may also be an on-off valve.

[0094] Alternatively, as Figure 1 As shown, the air supply module 100 further includes an air filter 60, which is disposed at the first end of the first flow path 51. The air filter 60 disposed at the first end of the first flow path 51 not only helps to reduce the cleanliness of the air delivered to the first gas system 200 and the second gas system 300, but also helps to reduce the impact of impurities in the air on valves, including the second valve 32, and other components.

[0095] In the present disclosure, the first end of the fourth flow path 54 is suitable for selectively communicating with the outside world, that is, the fourth flow path 54 can be connected to the outside world through the first flow path 51 or not, and the present disclosure does not limit this.

[0096] Alternatively, as Figure 1 As shown, the air supply module 100 also includes a first air storage device 71, which is arranged on the fourth flow path 54, and the first air storage device 71 is located downstream of the third valve 33. The first air storage device 71 has at least two different air storage pressure ranges, and the air supply module 100 is configured to be able to switch the air storage pressure range of the first air storage device 71 according to the outdoor temperature.

[0097] A certain amount of air can be stored by the first air storage device 71 for use in the second air consumption system 300 , which is beneficial to improving the stability and timeliness of the air flow delivered to the second air consumption system 300 .

[0098] Since air humidity and pressure are positively correlated, and the pressure of the air within the first air storage device 71 is proportional to the air volume, and since, at the same outdoor temperature, higher humidity within the first air storage device 71 increases the likelihood of freezing, which can affect the normal operation of the first air storage device 71, by switching the air storage pressure range of the first air storage device 71 according to the outdoor temperature, the humidity and pressure of the air within the first air storage device 71 can be matched to the outdoor temperature. This allows the first air storage system to store more air while ensuring that ice does not form within the first air storage device 71, thereby reducing the frequency of activation of the gas supply device 10 and reducing wear and energy consumption of the gas supply device 10.

[0099] It is understandable that the outdoor temperature can be measured by the vehicle's outdoor temperature sensor or by other means, and the present disclosure does not limit this.

[0100] In order to enable the air supply module 100 to switch the air storage pressure range of the first air storage device 71 according to the outdoor temperature, as an embodiment, at least two different air storage pressure ranges include a first air storage pressure range and a second air storage pressure range, and the upper limit of the first air storage pressure range is less than the upper limit of the second air storage pressure range. When the outdoor temperature is less than or equal to the preset temperature, the air supply module 100 maintains the air storage pressure range of the first air storage device 71 in the first air storage pressure range. When the outdoor temperature is greater than the preset temperature, the air supply module 100 switches the air storage pressure range of the first air storage device 71 from the first air storage pressure range to the second air storage pressure.

[0101] With such configuration, the first gas storage device 71 can have at least two gas storage pressure ranges for different temperatures, so as to ensure that the pressure and humidity of the air in the first gas storage device 71 match the outdoor temperature.

[0102] As another embodiment of the present disclosure, there may be at least three different gas storage pressure ranges, which respectively correspond to temperature intervals divided by two or more different preset temperatures.

[0103] The present disclosure does not limit the specific values of the preset temperature and the first gas storage pressure. As an embodiment, the preset temperature is 0°C and the first gas storage pressure ranges from 0.1 MPa to 0.6 MPa. That is, when the outdoor temperature is less than or equal to 0°C, the air supply module 100 maintains the gas storage pressure of the first gas storage device 71 within the range of 0.1 MPa to 0.6 MPa.

[0104] Since when the outdoor temperature is less than or equal to 0°C, if the humidity of the air in the first air storage device 71 is high, icing is likely to occur. Therefore, maintaining the air storage pressure of the first air storage device 71 at 0.1MPa~0.6MPa is beneficial to reducing the humidity of the air in the first air storage device 71, thereby helping to avoid icing in the first air storage device 71.

[0105] The present disclosure does not limit the specific values of the preset temperature and the second gas storage pressure. As an embodiment, the preset temperature is 0°C and the second gas storage pressure range is 0.1 MPa to 1.8 MPa. That is, when the outdoor temperature is greater than 0°C, the air supply module 100 switches the gas storage pressure range of the first gas storage device 71 to 0.1 MPa to 1.8 MPa.

[0106] Since when the outdoor temperature is greater than 0°C, the air in the first gas storage device 71 is not prone to freezing even if the humidity is high. Therefore, the gas storage pressure of the first gas storage device 71 is maintained at 0.1MPa~1.8MPa, allowing more air to be stored in the first gas storage device 71 for use by the second gas system 300, thereby reducing the frequency of starting the gas supply device 10, and further reducing the wear and energy consumption of the gas supply device 10.

[0107] Alternatively, as Figure 1 As shown, the second gas system 300 may further include a first pressure sensor 81 , which is used to detect the pressure of the air in the first gas storage device 71 , thereby providing data for controlling the pressure of the air in the first gas storage device 71 .

[0108] Alternatively, as Figure 1 As shown, the second gas system 300 may further include a pressure-limiting valve 91, which is disposed on the fourth flow path 54 and downstream of the second gas storage device 72. The pressure-limiting valve 91 can close when the pressure of the downstream air exceeds a set value, thereby ensuring that the pressure of the air in the second gas system 300 does not exceed a safe value. This helps prevent damage to equipment in the second gas system 300 caused by excessive pressure. Furthermore, by limiting the pressure, the humidity of the air in the second gas system 300 is maintained at a low level, thereby reducing the impact of moisture in the air on the second gas system 300 and preventing freezing in the second gas system 300 during winter.

[0109] Alternatively, as Figure 1 As shown, the second gas system 300 also includes a safety valve 92. The inlet of the safety valve 92 is connected to the fourth flow path 54 and is located downstream of the pressure-limiting valve 91. The outlet of the safety valve 92 is adapted to communicate with the outside world. If the pressure in the second gas system 300 unexpectedly rises, or if the pressure relief valve fails, the safety valve 92 can promptly discharge the air in the second gas system 300 to the outside world, thereby preventing damage to the second gas system 300 due to overpressure.

[0110] According to a second aspect of the present disclosure, a gas management system 1000 is provided. The gas management system 1000 includes a first gas use system 200 , a second gas use system 300 , and the above-mentioned gas supply module 100 .

[0111] Alternatively, as Figure 1As shown, the second air system 300 may include a fourth valve 34, a fifth valve 35, a second pressure sensor 82, and a second air device 301. The fourth valve 34 is connected between the air supply module 100 (i.e., the pressure-limiting valve 91 of the air supply module 100) and the second air device 301, and is also connected between the second air device 301 and the outside world. The fifth valve 35 can connect the fourth valve 34 to the outside world or block the connection between the fourth valve 34 and the outside world. The second pressure sensor 82 is used to detect the air pressure inside the second air device 301. The fourth valve 34 has valve positions five and six. In valve position five, the air supply module 100 is disconnected from the second air device 301, and the second air device 301 is connected to the fifth valve 35. In valve position six, the air supply module 100 is connected to the second air device 301, and the second air device 301 is disconnected from the fifth valve 35.

[0112] When supplying air to the second air-consuming device 301 , the fourth valve 34 may be switched to valve position six, so that the air from the air supply module 100 can enter the second air-consuming device 301 .

[0113] When the air supply to the second air-consuming device 301 is completed, the fourth valve 34 can be switched to valve position five, and the fifth valve 35 can be controlled to cut off the connection between the fourth valve 34 and the outside world, so that the air in the second air-consuming device 301 will neither flow back to the air supply module 100 nor leak to the outside world.

[0114] When the second gas-using device 301 is not in use, the fourth valve 34 can be kept in valve position five, and the fifth valve 35 can be controlled to connect the fourth valve 34 with the outside world, so that the air in the second gas-using device 301 can be discharged to the outside world, thereby preventing the moisture in the air in the second gas-using device 301 from freezing or corroding the second gas-using device 301 in winter.

[0115] It is understandable that the air in the second gas system 300 can be discharged by sequentially operating the valve actions corresponding to "when gas is supplied to the second gas device 301, when gas supply to the second gas device 301 ends, and when the second gas device 301 is not in use", thereby reducing the impact of moisture in the air on the second gas device 301.

[0116] In the present disclosure, the fourth valve 34, the fifth valve 35, the second pressure sensor 82 and the second gas-using device 301 can be provided as one group or as multiple groups, which is not limited in the present disclosure. For example, in an embodiment in which the second gas-using system 300 is a seat wing system, Figure 1 As shown, the fourth valve 34 , the fifth valve 35 , the second pressure sensor 82 and the second air-using device 301 may be two groups, wherein the two second air-using devices 301 may be the left airbag and the right airbag of the seat respectively.

[0117] Alternatively, as Figure 1 As shown, the first air-using system 200 may include a second air storage device 72, a first air-using device 201, a sixth valve 36, a seventh valve 37, and a third pressure sensor 83. The second air storage device 72 and the first air-using device 201 are both in communication with the air supply module 100 (i.e., the first valve 31 of the air supply module 100). The sixth valve 36 is connected between the second air storage device 72 and the air supply module 100, and the seventh valve 37 is connected between the first air-using device 201 and the air supply module 100. The third pressure sensor 83 is used to detect the pressure of the air between the sixth valve 36 and the air supply module 100, and between the seventh valve 37 and the air supply module 100.

[0118] When the air supply module 100 supplies air to the first air system 200, the sixth valve 36 can be opened to allow air to enter the second air storage device 72, and the second air storage device 72 can store a certain amount of air for use in the first air device 201 or for use in supplying air to the second air system 300.

[0119] By opening the seventh valve 37 , the first gas-using device 201 can be connected to the second gas storage device 72 or to the gas supply module 100 , so that the first gas-using device 201 can be inflated or deflated by utilizing the pressure difference.

[0120] In the present disclosure, the first air-using device 201, the sixth valve 36 and the seventh valve 37 can be set as one group or as multiple groups, which is not limited in the present disclosure. For example, in an embodiment where the first air-using system 200 is an air suspension system, Figure 1 As shown, the first air-consuming device 201 , the sixth valve 36 and the seventh valve 37 may be four groups, wherein the four first air-consuming devices 201 may be air springs for four wheels of the vehicle respectively.

[0121] The present disclosure does not limit the types of the first air system 200 and the second air system 300. As an embodiment, the first air system 200 may include an air suspension system, and / or the second air system 300 may include a seat wing system.

[0122] According to a third aspect of the present disclosure, a vehicle is provided, comprising the above-mentioned gas management system 1000 .

[0123] 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.

[0124] 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.

[0125] 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.
