Detailed Embodiments

[0041] The following describes in detail 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 illustration and explanation of the present disclosure, and are not intended to limit the present disclosure.

[0042] It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where the location is located and with the authorization given by the owner of the corresponding device.

[0043] In the present disclosure, unless otherwise stated, "inner" and "outer" refer to the inner and outer relative to the contour of the component or structure itself. In addition, it should be noted that the terms such as "first", "second", etc. are used to distinguish one element from another, and do not have sequence and importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0044] According to a first aspect of the present disclosure, a housing assembly is provided. Refer to Figures 1 to 13As shown, the housing assembly is used for a gas compression device and includes a housing 1 and a first flow channel 4. The housing 1 has a receiving cavity 110 for receiving a piston mechanism 2, and the receiving cavity 110 is divided into a primary compression chamber 111 and a first intake chamber 113 by the piston mechanism 2. The first flow channel 4 communicates with the primary compression chamber 111 and the first intake chamber 113, and at least part of the first flow channel 4 is formed on the housing 1 for allowing gas to enter the primary compression chamber 111 from the first intake chamber 113.

[0045] Through the above technical solution, that is, the housing assembly provided by the present disclosure, by connecting the first flow channel 4 to the primary compression chamber 111 and the first intake chamber 113, the gas in the first intake chamber 113 can enter the primary compression chamber 111 via the first flow channel 4. And at least part of the first flow channel 4 is formed on the housing 1. That is, it can be understood that, for example, the first flow channel 4 can be entirely formed on the housing 1 or part of it can be formed on the housing 1 and the other part can be formed on the end cover to achieve the connection between the first intake chamber 113 and the primary compression chamber 111, without the need to open through holes in the piston mechanism as in the related art to connect the first intake chamber to the primary compression chamber, which can simplify the structure of the piston mechanism 2, make the installation and manufacturing of the piston mechanism 2 more convenient, reduce the production difficulty, and at the same time is conducive to the reciprocating movement of the piston 210 of the piston mechanism 2 in the receiving cavity 110 under the drive of a drive mechanism 5 (to be described below). The piston 210 has better symmetry and moves more smoothly. In this way, when the above housing assembly is applied to, for example, a gas compression device, it is beneficial to ensure the long-term stable operation of the gas compression device and optimize the performance of the gas compression device.

[0046] In some embodiments, referring to Figure 11 As shown, a second one-way valve 11 can be provided between the primary compression chamber 111 and the first intake chamber 113. For example, the second one-way valve 11 can be arranged at the outlet where the second flow channel section 420 communicates with the primary compression chamber 111. In this way, the gas in the first intake chamber 113 can be filled into the primary compression chamber 111 through the second one-way valve 11, but the gas in the primary compression chamber 111 cannot flow back to the first intake chamber 113, and the structure is simple and convenient for installation and manufacturing.

[0047] Of course, the specific embodiment of arranging the second one-way valve 11 at the outlet where the second flow channel section 420 communicates with the primary compression chamber 111 is exemplary. In some other embodiments not shown, the second one-way valve 11 can also be arranged at the inlet where the second flow channel section 420 communicates with the first intake chamber 113. The present disclosure is not limited to this, and the purpose is to enable the gas to enter the primary compression chamber 111 from the first intake chamber 113 and avoid gas backflow. Those skilled in the art can design adaptively according to actual application requirements.

[0048] In some embodiments, with reference to Figures 11 to 13 as shown, the housing 1 may include a first housing body 120 and a first end cap 130. The first housing body 120 and the first end cap 130 together define a receiving cavity 110. The first flow channel 4 may include a first flow channel segment 410 and a second flow channel segment 420 that are connected and communicate with each other. The first flow channel segment 410 is formed on the first housing body 120, and one end away from the second flow channel segment 420 communicates with the first intake chamber 113. The second flow channel segment 420 is formed on the first end cap 130, and one end away from the first flow channel segment 410 communicates with the first-stage compression chamber 111. The structure is simple and convenient for installation and manufacturing.

[0049] Of course, the specific embodiments of the above first flow channel 4 are exemplary. In some other embodiments not shown, the first flow channel 4 may also be directly formed on the first housing body 120. The present disclosure is not limited thereto, and those skilled in the art can adaptively design according to actual application requirements. The purpose is to be able to achieve the communication between the first intake chamber 113 and the first-stage compression chamber 111 through the first flow channel 4.

[0050] In some embodiments, with reference to Figures 1 to 13 as shown, the receiving cavity 110 may further include a second-stage compression chamber 112. The first-stage compression chamber 111, the first intake chamber 113, and the second-stage compression chamber 112 are sequentially separated and arranged at intervals by a piston mechanism 2. The first-stage compression chamber 111 communicates with the second-stage compression chamber 112 through a heat dissipation flow channel 3, so that the gas flowing through the inside of the heat dissipation flow channel 3 can be dissipated. In this way, when the above housing assembly is applied to, for example, a gas compression device, the internal temperature of the gas compression device can be reduced, which is beneficial to ensuring the long-term stable operation of the gas compression device and optimizing the performance of the gas compression device.

[0051] In addition, in some embodiments, with reference to Figures 1 to 13As shown, the heat dissipation flow channel 3 can be at least partially formed on the outer shell 1. That is, it can be understood that, for example, the heat dissipation flow channel 3 can be entirely formed on the outer shell 1 or the communication between the primary compression chamber 111 and the secondary compression chamber 112 can be achieved through a heat dissipation pipeline located outside the outer shell 1, for example. In this way, it is convenient to dissipate heat from the gas flowing through the interior of the heat dissipation flow channel 3. Moreover, the heat dissipation flow channel 3 is located outside the accommodation chamber 110 of the outer shell 1, and the heat dissipation effect is better, which is more conducive to ensuring the long-term stable operation of the gas compression device. That is, it can be understood that, compared with the related art, in the related art, since the air passage connecting the primary compression chamber and the secondary compression chamber is located inside the accommodation chamber of the outer shell, the internal temperature of the gas compression device is too high during long-term operation, which is not conducive to the heat dissipation of the gas in the air passage, and the overall structure has a poor heat dissipation effect. However, in the housing assembly provided by the present disclosure, by forming the heat dissipation flow channel 3 at least partially on the outer shell 1, that is, the heat dissipation flow channel 3 is located outside the accommodation chamber 110 of the outer shell 1, it is more conducive to the heat dissipation of the gas in the heat dissipation flow channel 3, and the heat dissipation effect is better. In addition, by arranging the heat dissipation flow channel 3 communicating with the primary compression chamber 111 and the secondary compression chamber 112 on the outer shell 1, compared with the related art where the air passage connecting the primary compression chamber and the secondary compression chamber is arranged on the piston mechanism, it is obvious that the housing assembly provided by the present disclosure can better simplify the structure of the piston mechanism 2, is more convenient for the installation and manufacture of the piston mechanism 2, and reduces the production difficulty.

[0052] In addition, in some embodiments, with reference to Figures 1 to 13 As shown, the heat dissipation flow channel 3 can be connected with a third one-way valve 12 so that the gas can enter the secondary compression chamber 112 from the primary compression chamber 111 through the heat dissipation flow channel 3. That is, it can be understood that a third one-way valve 12 can be arranged between the heat dissipation flow channel 3 and the secondary compression chamber 112. For example, the third one-way valve 12 can be arranged at the second communication port 121. In this way, the gas in the primary compression chamber 111 can be filled into the secondary compression chamber 112 through the heat dissipation flow channel 3 by means of the third one-way valve 12, but the gas in the secondary compression chamber 112 cannot flow back into the primary compression chamber 111, thus avoiding the problem of gas backflow.

[0053] Among them, the embodiment where the above-mentioned third one-way valve 12 is arranged at the second communication port 121 is exemplary. In some other embodiments, the third one-way valve 12 can also be arranged on the heat dissipation flow channel 3 or at the first communication port 131. The present disclosure is not limited thereto.

[0054] In addition, any well-known one-way valve structure in the art can be selected for the above-mentioned one-way valve to achieve the one-way flow of the gas and avoid the problem of gas backflow. The present disclosure will not elaborate too much here, and those skilled in the art can adaptively design according to actual application requirements.

[0055] It should be noted that in the vertical direction, reference can be made to Figure 11 the up and down directions of the drawing surface of Figure 11 . The primary compression chamber 111 can be arranged below the secondary compression chamber 112. Of course, the specific embodiment where the primary compression chamber 111 is arranged below the secondary compression chamber 112 is exemplary. In some other embodiments not shown, the primary compression chamber 111 can also be arranged above the secondary compression chamber 112. Or, in some other embodiments not shown, the primary compression chamber 111 and the secondary compression chamber 112 can also be arranged at intervals in the horizontal direction. The horizontal direction can refer to Figure 11 the left and right directions of the drawing surface of Figure 11 . The present disclosure does not make specific limitations on such deformation modes. Those skilled in the art can adaptively design according to actual application requirements, and the present disclosure is not limited thereto.

[0056] The present disclosure will specifically illustrate by taking the example that the primary compression chamber 111 is arranged below the secondary compression chamber 112:

[0057] In some embodiments, referring to Figures 11 to 13 as shown in Figures 11 to 13 , the heat dissipation flow channel 3 can include a first heat exchange flow channel section 310 formed outside the housing 1, and both ends of the first heat exchange flow channel section 310 are respectively communicated with the primary compression chamber 111 and the secondary compression chamber 112. In this way, by arranging the heat dissipation flow channel 3 outside the housing 1, it is more conducive to the heat dissipation of the gas in the heat dissipation flow channel 3, ensuring a higher heat dissipation effect and being beneficial to the long-term stable operation of the gas compression device.

[0058] Of course, the specific embodiment where the heat dissipation flow channel 3 includes the first heat exchange flow channel section 310 formed outside the housing 1 is exemplary. In some other embodiments, referring to Figures 8 to 10 as shown in Figures 8 to 10 , the heat dissipation flow channel 3 can also include a second heat exchange flow channel section 320 formed on the housing 1, and both ends of the second heat exchange flow channel section 320 are respectively communicated with the primary compression chamber 111 and the secondary compression chamber 112. In this way, by arranging the heat dissipation flow channel 3 outside the accommodation chamber 110 of the housing 1, on the one hand, it is more conducive to the heat dissipation of the gas in the heat dissipation flow channel 3, ensuring a higher heat dissipation effect and being beneficial to the long-term stable operation of the gas compression device. On the other hand, at least part of the space of the housing 1 can be directly utilized, the structure is simpler and the space occupancy rate is lower. Thus, when the housing assembly is applied to, for example, a gas compression device, the occupancy rate of the installation space of the housing assembly can be reduced to have a higher space utilization rate.

[0059] It should be noted that the specific embodiments of the heat dissipation flow channel 3 of the present disclosure are not limited to the above two embodiments. For example, in some other embodiments not shown in the figures, the heat dissipation flow channel 3 may also include a second heat exchange flow channel section 320 formed on the housing 1 and a first heat exchange flow channel section 310 formed outside the housing 1. In this way, one end of the second heat exchange flow channel section 320 can be connected to the primary compression chamber 111, the other end can be connected to one end of the first heat exchange flow channel section 310, and the other end of the first heat exchange flow channel section 310 can be connected to the secondary compression chamber 112. The present disclosure is not limited to this, and those skilled in the art can adaptively design according to actual application requirements, and the purpose is to be able to connect to the primary compression chamber 111 and the secondary compression chamber 112 through the heat dissipation flow channel 3.

[0060] In addition, it should be noted that the above heat dissipation flow channel 3 can be provided with a heat dissipation part (not shown in the figure) outside, for example, to dissipate the heat of the gas in the heat dissipation flow channel 3. The heat dissipation part can be constructed in any suitable way. For example, the heat dissipation part can include a fan to cool the above-mentioned first heat exchange flow channel section 310 and second heat exchange flow channel section 320 by blowing air in an air-cooling manner to dissipate the heat of the gas inside the heat dissipation flow channel 3. Or, the heat dissipation part can also include a nozzle to cool the above-mentioned first heat exchange flow channel section 310 and second heat exchange flow channel section 320 by spraying water in a water-cooling manner. Or, heat dissipation fins can also be provided on the first heat exchange flow channel section 310 and / or the second heat exchange flow channel section 320 to dissipate heat by means of, for example, external wind power. Of course, air-cooling, water-cooling or heat dissipation fins can also be used simultaneously, or any other way that can cool the first heat exchange flow channel section 310 and the second heat exchange flow channel section 320 can be used to cool the gas in the heat dissipation flow channel 3. The present disclosure does not make specific limitations on this.

[0061] In some embodiments, referring to Figures 11 to 13 As shown, the housing 1 may include a first housing 120 and a first end cap 130. The first housing 120 and the first end cap 130 together enclose an accommodation chamber 110. A first communication port 131 is provided on the first end cap 130, and a second communication port 121 is provided on the first housing 120. One end of the heat dissipation flow channel 3 is connected to the primary compression chamber 111 through the first communication port 131, and the other end of the heat dissipation flow channel 3 is connected to the secondary compression chamber 112 through the second communication port 121, so as to connect to the primary compression chamber 111 and the secondary compression chamber 112 through the heat dissipation flow channel 3. In this way, there is no need to modify the piston mechanism 2, which can make the structure of the piston mechanism 2 simpler, facilitate on-site installation and manufacturing, and reduce the on-site production difficulty and production cost.

[0062] Of course, the specific embodiments of the above housing 1 are exemplary. In some other embodiments, referring to Figure 4As shown, the housing 1 may also include a first housing body 120, a first end cover 130, and a second end cover 140. The first housing body 120, the first end cover 130, and the second end cover 140 together enclose a receiving cavity 110. A first communication port 131 is provided on the first end cover 130, and a third communication port (not shown) is provided on the second end cover 140. One end of the heat dissipation flow channel 3 communicates with the primary compression chamber 111 through the first communication port 131, and the other end of the heat dissipation flow channel 3 communicates with the secondary compression chamber 112 through the third communication port, so as to realize the communication between the primary compression chamber 111 and the secondary compression chamber 112 through the heat dissipation flow channel 3.

[0063] Alternatively, in other embodiments, the housing 1 may further include a first housing body 120. A fourth communication port (not shown) and a second communication port 121 are provided on the first housing body 120. One end of the heat dissipation flow channel 3 communicates with the primary compression chamber 111 through the fourth communication port, and the other end of the heat dissipation flow channel 3 communicates with the secondary compression chamber 112 through the second communication port 121. The present disclosure is not limited thereto, and those skilled in the art can adaptively design according to actual application requirements. That is, it can be understood that those skilled in the art can realize the communication between the heat dissipation flow channel 3 and the compression chamber through the communication port on the end cover, and / or can also realize the communication between the heat dissipation flow channel 3 and the compression chamber through the communication port opened on the outer wall of the first housing body 120.

[0064] According to a second aspect of the present disclosure, a gas compression device is provided. Refer to Figures 11 to 13 As shown, the gas compression device includes a piston mechanism 2 and the above-mentioned housing assembly, so as to simplify the structure of the piston mechanism, facilitate the installation and manufacture of the piston mechanism, reduce the production difficulty, and at the same time facilitate the more stable reciprocating movement of the piston. In addition, the gas compression device also has all the beneficial effects of the above-mentioned housing assembly, which will not be elaborated herein.

[0065] In some embodiments, refer to Figures 11 to 13 As shown, the gas compression device may further include a driving mechanism 5. The driving mechanism 5 is drivingly connected to the piston mechanism 2 to drive the piston 210 of the piston mechanism 2 to reciprocate in the vertical direction. And the piston mechanism 2 divides the receiving cavity 110 into a primary compression chamber 111, a first intake chamber 113, and a secondary compression chamber 112 that are arranged at intervals in sequence. The structure is simpler and convenient for on-site installation and manufacture.

[0066] Among them, it should be noted that Figure 11Exemplarily, during the reciprocating movement of the piston 210 relative to the first housing 120 in the vertical direction, the volume change of the primary compression chamber 111 is greater than that of the secondary compression chamber 112. Thus, when the piston 210 moves upward relative to the first housing 120 in the vertical direction, for example, since the volume of the primary compression chamber 111 increases and the pressure decreases, the gas in the first intake chamber 113 can be filled into the primary compression chamber 111. When the piston 210 moves downward relative to the first housing 120 in the vertical direction, since the volume of the primary compression chamber 111 decreases, the gas is compressed once in the primary compression chamber 111 and the pressure increases. When the pressure in the primary compression chamber 111 is greater than that in the secondary compression chamber 112, the gas in the primary compression chamber 111 is discharged into the secondary compression chamber 112. As the piston 210 continues to move upward relative to the first housing 120 in the vertical direction, the gas in the secondary compression chamber 112 is compressed a second time to discharge the highly compressed gas after the second compression to the outside of the housing 1, for example, it can be discharged to the air spring of the air suspension system of the vehicle, thereby improving the comfort, driving performance, and passability of the vehicle.

[0067] In addition, in some embodiments, as Figures 11 to 13 shown, the housing 1 may be provided with a first inlet / outlet 6 communicating with the first intake chamber 113. The first inlet / outlet 6 can communicate with, for example, the outside atmosphere. Thus, while enabling the intake and exhaust of the first intake chamber 113 through the first inlet / outlet 6, it is also convenient to discharge the heat inside the housing 1 through the first inlet / outlet 6, further improving the heat dissipation effect of the gas compression device and ensuring the long-term stable operation of the gas compression device.

[0068] In addition, Figure 9 and Figure 10 exemplarily shows that the drive mechanism 5 may include a third housing 510. The third housing 510 has a third intake chamber 520 and a second inlet / outlet 530 communicating with the third intake chamber 520. Thus, while enabling the intake and exhaust of the third intake chamber 520 through the second inlet / outlet 530, it is also convenient to discharge the heat inside the third housing 510 through the second inlet / outlet 530, improving the heat dissipation effect of the drive mechanism 5 and being conducive to ensuring the long-term stable operation of the gas compression device.

[0069] Exemplarily, in some embodiments, as Figure 10As shown, a first inlet and outlet 6 is provided on the shell 1 and a second inlet and outlet 530 is provided on the driving mechanism 5, which can be arranged at the same time, so as to realize the air inlet and outlet inside the gas compression device, and at the same time realize the discharge of heat generated during the operation of the driving mechanism 5 and the internal components of the shell 1, which is beneficial to ensure that the gas compression device can work stably for a long time, and the third air inlet chamber 520 can be connected to the first flow channel 4 through the first air inlet chamber 113, or the third air inlet chamber 520 can also be directly connected to the first flow channel 4. The present disclosure does not make specific limitations on such deformation methods, and its purpose is to realize the inflation operation in the first compression chamber 111 through the first inlet and outlet 6 and / or the second inlet and outlet 530. Those skilled in the art can design adaptively according to actual application requirements.

[0070] Of course, the above-mentioned specific embodiment in which the first inlet and outlet 6 and the second inlet and outlet 530 are arranged at the same time is exemplary. In other embodiments, the first inlet and outlet 6 may be arranged only on the housing 1 or the second inlet and outlet 530 may be arranged only on the driving mechanism 5, and the present disclosure does not specifically limit this. In addition, it should be noted that the present disclosure does not specifically limit the specific opening size of the first inlet and outlet 6 and the second inlet and outlet 530 and the corresponding arrangement quantity, and those skilled in the art can design adaptively according to actual application requirements.

[0071] In addition, the present disclosure does not make any specific limitation on the specific structure of the driving mechanism 5. Those skilled in the art may select a driving motor as a driving component that is well known in the art according to actual application requirements to realize the driving of the piston mechanism 2 by electric drive. Of course, in other embodiments, the driving of the piston mechanism 2 may also be realized by driving methods such as pneumatic or hydraulic pressure. The present disclosure does not make any specific limitation on this. The purpose is to realize the reciprocating movement of the piston mechanism 2 by the driving mechanism 5.

[0072] In some embodiments, reference Figures 1 to 13 As shown, the gas compression device also includes a temperature detection component for detecting the temperature of the gas in the gas compression device, so as to accurately monitor the temperature condition of the gas compression device in real time, thereby taking targeted and effective temperature adjustment measures to ensure that the gas compression device works stably for a long time.

[0073] Among them, the temperature monitoring component can be constructed in any suitable manner. For example, a person skilled in the art can select a temperature sensor known in the art to detect the temperature of the gas in the gas compression device, and by connecting the temperature sensor to, for example, a controller (not shown) signal, the controller can receive the temperature information detected by the temperature sensor, and then can make targeted and effective temperature adjustment measures to ensure that the gas compression device works stably for a long time.

[0074] It should be noted that the above-mentioned controller can be a separately arranged controller such as a PLC controller or a single-chip microcomputer, etc., or it can also be, for example, an electronic control unit (ECU) of a vehicle. The present disclosure does not make specific limitations on this, and the above-mentioned controller can be signal-connected to the above-mentioned actuators such as temperature sensors in a wireless or wired manner. Since the signal connection method and data transmission method between the above-mentioned controller and each actuator and other aspects are well-known in the art, the controller can achieve this, and no more details will be described here.

[0075] According to the third aspect of the present disclosure, referring to Figures 11 to 13 As shown, a gas supply device is provided. The gas supply device includes the above-mentioned gas compression device, so as to simplify the structure of the piston mechanism, make it more convenient for the installation and manufacture of the piston mechanism, reduce the production difficulty, and at the same time, it is also beneficial for the piston to reciprocate more smoothly. In addition, the gas supply device also has all the beneficial effects of the above-mentioned gas compression device, and the present disclosure will not repeat them here.

[0076] In some embodiments, referring to Figures 11 to 13 As shown, the gas supply device may further include a drying and filtering module 7. The drying and filtering module 7 includes a second housing 710. The second housing 710 has a second intake chamber 711. A filter element 720 is disposed in the second intake chamber 711. The outer peripheral wall of the filter element 720 abuts against the inner peripheral wall of the second intake chamber 711 to divide the second intake chamber 711 into a first chamber 7111 and a second chamber 7112. The first chamber 7111 communicates with the secondary compression chamber 112, and the second chamber 7112 is used to communicate with the air spring. In this way, the high-pressure gas discharged from the secondary compression chamber 112 can pass through the drying and filtering module 7 for drying and filtering and then be discharged to the air spring of the vehicle's air suspension system, which is beneficial to ensuring the long-term stable operation of the gas supply device. In addition, since the outer peripheral wall of the above-mentioned filter element 720 directly abuts against the inner peripheral wall of the second intake chamber 711 of the second housing 710, that is, the filter housing arranged outside the filter element in the related art is cancelled, the number of parts is simplified. While being beneficial to the overall lightweight design of the gas supply device, it can also improve the space utilization rate of the desiccant in the filter element 720 and improve the drying and filtering effect of the high-pressure gas discharged to the air spring.

[0077] In addition, in some embodiments, referring to Figure 11As shown, a fourth one-way valve 13 can be provided between the secondary compression chamber 112 and the first chamber 7111. For example, the fourth one-way valve 13 can be arranged at the exhaust port where the secondary compression chamber 112 communicates with the first chamber 7111. In this way, the gas in the secondary compression chamber 112 can be discharged into the first chamber 7111 through the fourth one-way valve 13, but the gas in the first chamber 7111 cannot flow back into the secondary compression chamber 112. Among them, the fourth one-way valve 13 can select any well-known one-way valve structure in the art to achieve the one-way flow of gas and avoid the problem of gas backflow. The present disclosure will not elaborate too much here, and those skilled in the art can adaptively design according to actual application requirements.

[0078] In addition, the present disclosure does not specifically limit the specific structure of the filter element 720 either. Those skilled in the art can adaptively design according to actual application requirements, and its purpose is to be able to achieve the drying and filtering of high-pressure gas.

[0079] In some embodiments, referring to Figures 11 to 13 As shown, the gas supply device may further include a pressure relief member 8 provided outside the second housing 710. A pressure relief pipe 9 communicating with the pressure relief member 8 is provided in the second intake chamber 711, and the pressure relief member 8 has a first one-way valve 810 provided at the connection between the pressure relief member 8 and the pressure relief pipe 9, so as to be able to keep the system pressure in the gas supply device within a set pressure range, avoid accidents caused by too high system pressure, and improve the safety of the system.

[0080] And, as Figure 11 shown, the filter element 720 can be sleeved on the pressure relief pipe 9. In this way, not only can the pressure relief operation be carried out in time when the system pressure is too high through the pressure relief pipe 9, but also the installation and fixation of the filter element 720 can be realized through the pressure relief pipe 9, with high integration and improved space utilization.

[0081] In addition, as Figure 13 shown, the intake port 910 of the pressure relief pipe 9 can communicate with the first chamber 7111. In this way, when the gas supply device is in, for example, a deflation operation, that is, the gas discharged from, for example, the air spring can flow through the filter element 720 in the direction of the arrow in Figure 13 , which can better realize the removal of at least part of the moisture in the desiccant in the filter element 720 and discharge it into, for example, the outside atmosphere through the pressure relief pipe 9, and can effectively extend the service life of the drying and filtering module 7.

[0082] In addition, in some embodiments, referring to Figures 11 to 13As shown in the figure, the pressure relief member 8 may include a pressure relief valve 820 and a solenoid valve 830 that are connected and communicate with each other. The pressure relief valve 820 is connected to the pressure relief pipe 9, and the first check valve 810 is provided at the connection. The pressure relief valve 820 is connected to the first intake chamber 113 through the first pipe 14. The pressure relief valve 820 is bypassed to the second pipe 15 where the second chamber 7112 communicates with the air spring through the third pipe 16. And the third pipe 16 includes a first branch 1610 and a second branch 1620 arranged in parallel. A solenoid valve 830 is provided at the connection of the first branch 1610 and the second branch 1620. In this way, through the arrangement of the pressure relief valve 820 and the solenoid valve 830, the switching of the inflation, deflation, and air release working processes of the air supply device can be realized (the specific working process will be described in detail below), and the controllability is good.

[0083] Among them, the present disclosure does not specifically limit the specific structures of the pressure relief valve 820 and the solenoid valve 830. Those skilled in the art can select any well-known structures of the pressure relief valve 820 and the solenoid valve 830 in the art, and the present disclosure will not elaborate too much here. In addition, it should be noted that the pressure relief operation of the pressure relief valve 820 may be to discharge the high-pressure gas in the second intake chamber 711 to the first intake chamber 113 through the first pipe 14 and then discharge the high-pressure gas to the outside atmosphere through the first inlet and outlet 6. Or, the first pipe 14 of the pressure relief valve 820 may not be connected to the first intake chamber 113, and the first pipe 14 of the pressure relief valve 820 is directly connected to the outside atmosphere to achieve the pressure relief operation. The present disclosure is not limited to this.

[0084] According to the fourth aspect of the present disclosure, an air suspension system is provided, including an air spring and the above-mentioned air supply device. This air suspension system has all the beneficial effects of the above-mentioned air supply device, and the present disclosure will not elaborate here.

[0085] According to the fifth aspect of the present disclosure, a vehicle is provided, including the above-mentioned air suspension system. This vehicle has all the beneficial effects of the above-mentioned air suspension system, and the present disclosure will not elaborate here.

[0086] Based on the above embodiments, the present disclosure exemplarily describes the inflation, deflation, and air release working processes of the air supply device as follows:

[0087] a. Inflation of the air supply device:

[0088] As Figure 11 shown, by controlling the solenoid valve 830, the third pipe 16 and the second pipe 15 are not connected. At this time, the first check valve 810 of the pressure relief valve 820 is in a normally closed state under the action of the spring force F1, that is, the pressure relief valve 820 is not connected to the inside of the second intake chamber 711 at this time;

[0089] The driving mechanism 5 drives the piston mechanism 2 to reciprocate vertically relative to the first housing 120. When the piston 210 of the piston mechanism 2 moves upward vertically relative to the first housing 120, due to the increase in the volume of the primary compression chamber 111 and the decrease in pressure, the second one-way valve 11 opens, allowing the gas in the first intake chamber 113 to be filled into the primary compression chamber 111 through the second one-way valve 11;

[0090] When the piston 210 moves downward vertically relative to the first housing 120, due to the decrease in the volume of the primary compression chamber 111, the gas is compressed once in the primary compression chamber 111, and the pressure increases. The second one-way valve 11 closes. When the pressure in the primary compression chamber 111 is greater than the pressure in the secondary compression chamber 112, the third one-way valve 12 opens, allowing the gas in the primary compression chamber 111 to be discharged into the secondary compression chamber 112 through the heat dissipation channel 3, and the gas can be cooled during the process of flowing through the heat dissipation channel 3;

[0091] When the piston 210 continues to move upward vertically relative to the first housing 120, the gas in the secondary compression chamber 112 is compressed twice, and the third one-way valve 12 closes. When the gas pressure in the secondary compression chamber 112 reaches the opening value of the fourth one-way valve 13, the fourth one-way valve 13 opens, allowing the highly compressed gas after double compression to be discharged into the second intake chamber 711, and after being dried and filtered by the filter element 720, it is discharged through the second pipeline 15 to the air spring of the air suspension system of the vehicle, thereby improving the comfort, driving performance and passability of the vehicle.

[0092] b. Air leakage of the air supply device:

[0093] As Figure 12 shown, when the gas pressure in the second intake chamber 711 is too high and exceeds the safety pressure set by the pressure relief valve 820, the acting force F2 of the high-pressure gas on the first one-way valve 810 of the pressure relief valve 820 exceeds the spring force F1, that is, F2 is greater than F1, the spring is compressed, the first one-way valve 810 opens, and the air supply device starts to release pressure, avoiding accidents caused by too high system pressure and improving the safety of the system.

[0094] c. Air release of the air supply device:

[0095] As Figure 13As shown, by controlling the solenoid valve 830, the second branch 1620 of the third pipe 16 is connected to the second pipe 15, and at this time, the fourth one-way valve 13 is in the closed state. The high-pressure gas from the air spring of the vehicle's air suspension system is discharged into the second intake chamber 711 and the pressure relief valve 820 respectively via the second pipe 15. At this time, the acting force (F2 + F3) of the high-pressure gas on the valve core of the pressure relief valve 820 exceeds the spring force F1, that is, (F2 + F3) is greater than F1, the spring is compressed, and the first one-way valve 810 opens, enabling the high-pressure gas from the air spring of the vehicle's air suspension system to be discharged to the first intake chamber 113 via the first pipe 14 and discharged into the outside atmosphere via the first inlet and outlet 6;

[0096] Moreover, during the deflation process of the air supply device, since the high-pressure gas discharged from the air spring of the vehicle's air suspension system can flow through the filter element 720 in the direction of the arrow in Figure 13 it can better carry out at least part of the moisture in the desiccant in the filter element 720 and discharge it into the outside atmosphere via the pressure relief pipe 9, effectively extending the service life of the dry filtering module 7.

[0097] During rapid startup, by controlling the solenoid valve 830 to open the pressure relief valve 820, the gas with a certain pressure from the gas compression device (for example, from the secondary compression chamber 112) flows back to the first intake chamber 113 of the gas compression device through the dry filtering module 7, and then quickly reaches the working pressure after compression. Then, control the solenoid valve 830 to close the pressure relief valve 820, facilitating the air supply device to quickly switch to the inflation state.

[0098] The preferred embodiments of the present disclosure have been described in detail above in conjunction with 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 fall within the protection scope of the present disclosure.

[0099] In addition, it should be noted that, among 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 methods.

[0100] Furthermore, any combination can be made between 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.
