DETAILED DESCRIPTION

[0043] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0044] It should be noted that all actions of obtaining signals, information or data in the present disclosure are performed in compliance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization given by the corresponding device owner.

[0045] In the present disclosure, "inner, outer" refers to the inner, outer relative to the outline of the component or structure itself, unless otherwise stated. In addition, it should be noted that the terms such as "first, second" used are for distinguishing one element from another, and do not have sequential and important meanings. In addition, in the description with reference to the drawings, the same reference signs in different drawings represent the same elements.

[0046] According to a first aspect of the present disclosure, a housing assembly 100 is provided for a gas compression device 200, and comprises a housing 1 having a receiving cavity 110 for accommodating a piston assembly 2 to divide the receiving cavity 110 into a primary compression chamber 111 and a first intake chamber 113 by the piston assembly 2; and a first flow passage 4 communicating with the primary compression chamber 111 and the first intake chamber 113, the first flow passage 4 being at least partially formed on the housing 1 for allowing gas to enter the primary compression chamber 111 from the first intake chamber 113.

[0047] With the above technical solution, i.e. the housing assembly 100 provided by the present disclosure, by communicating the first flow passage 4 with 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 through the first flow passage 4, and the first flow passage 4 is at least partially formed on the housing 1, i.e. it can be understood that the first flow passage 4 can be formed entirely on the housing 1 or partially on the housing 1 and partially on the end cover to realize the communication between the first intake chamber 113 and the primary compression chamber 111. Unlike the related art, the first intake chamber is communicated with the primary compression chamber by a through hole formed on the piston assembly, so that the structure of the piston assembly 2 can be simplified, the installation and manufacturing of the piston assembly 2 are more convenient, the production difficulty is reduced, and the piston 210 of the piston assembly 2 is more symmetrical and moves more smoothly under the driving of the driving assembly 5 (to be described below) in the receiving cavity 110. Therefore, when the above housing assembly 100 is applied to the gas compression device 200, it is beneficial to ensure that the gas compression device 200 works stably for a long time and optimizes the performance of the gas compression device 200.

[0048] In some embodiments, referring to FIG. 11, 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 gas outlet of the second flow passage segment 420 communicating with the primary compression chamber 111. In this way, the second one-way valve 11 can be used to fill the gas in the first intake chamber 113 into the primary compression chamber 111, but cannot make the gas in the primary compression chamber 111 flow back to the first intake chamber 113, which is simple in structure and convenient to install and manufacture.

[0049] Of course, the above-mentioned specific embodiment that the second one-way valve 11 is arranged at the gas outlet of the second flow passage section 420 and the primary compression chamber 111 is exemplary, in other unillustrated embodiments, the second one-way valve 11 can also be arranged at the gas inlet of the second flow passage section 420 and the first gas inlet chamber 113, and the present disclosure is not limited thereto, and the purpose is to enable the gas to flow from the first gas inlet chamber 113 to the primary compression chamber 111, and avoid backflow of the gas.

[0050] In some embodiments, referring to FIGS. 11-13, the housing 1 can include a first shell 120 and a first end cover 130, and the first shell 120 and the first end cover 130 jointly define the accommodation cavity 110. The first flow passage 4 can include a first flow passage section 410 and a second flow passage section 420 in communication. The first flow passage section 410 is formed on the first shell 120 and communicates with the first gas inlet chamber 113 at an end away from the second flow passage section 420. The second flow passage section 420 is formed on the first end cover 130 and communicates with the primary compression chamber 111 at an end away from the first flow passage section 410. The structure is simple and facilitates installation and manufacturing.

[0051] Of course, the above-mentioned specific embodiment that the first flow passage 4 is exemplary, in other unillustrated embodiments, the first flow passage 4 can also be directly formed on the first shell 120, and the present disclosure is not limited thereto, and those skilled in the art can adaptively design according to actual application requirements, and the purpose is to enable the first gas inlet chamber 113 and the primary compression chamber 111 to be communicated through the first flow passage 4.

[0052] In some embodiments, referring to FIGS. 1-13, the accommodation cavity 110 can further include a secondary compression chamber 112. The primary compression chamber 111, the first gas inlet chamber 113, and the secondary compression chamber 112 are sequentially separated and spaced apart by the piston assembly 2. The primary compression chamber 111 communicates with the secondary compression chamber 112 through the heat dissipation flow passage 3, so that the gas flowing through the inside of the heat dissipation flow passage 3 can be cooled through the heat dissipation flow passage 3. In this way, when the above-mentioned shell assembly 100 is applied to, for example, the gas compression device 200, the temperature inside the gas compression device 200 can be reduced, which is conducive to ensuring that the gas compression device 200 works stably for a long time and optimizes the performance of the gas compression device 200.

[0053] In addition, in some embodiments, referring to FIGS. 1-13, the heat dissipation flow channel 3 can be formed at least partially on the shell 1, that is, it can be understood that, for example, the heat dissipation flow channel 3 can be formed entirely on the shell 1 or can also be achieved by, for example, a heat dissipation pipe located outside the shell 1 to realize the communication of the primary compression chamber 111 and the secondary compression chamber 112, so that the heat dissipation flow channel 3 can facilitate heat dissipation of the gas flowing through the inside of the heat dissipation flow channel 3, and the heat dissipation flow channel 3 is located outside the containing cavity 110 of the shell 1, which is more conducive to ensuring that the gas compression device 200 works stably for a long time, that is, it can be understood that, compared with the related art, since the gas passage communicating the primary compression chamber and the secondary compression chamber in the related art is located inside the containing cavity of the shell, the internal temperature of the gas compression device 200 is too high for a long time, which is not conducive to heat dissipation of the gas in the gas passage, and the overall structure has poor heat dissipation effect. The shell assembly 100 provided by the present disclosure can more facilitate heat dissipation of the gas in the heat dissipation flow channel 3 by forming the heat dissipation flow channel 3 at least partially on the shell 1, that is, the heat dissipation flow channel 3 is located outside the containing cavity 110 of the shell 1, which has better heat dissipation effect. In addition, by arranging the heat dissipation flow channel 3 communicating the primary compression chamber 111 and the secondary compression chamber 112 on the shell 1, compared with the related art in which the gas passage communicating the primary compression chamber and the secondary compression chamber is arranged on the piston assembly, it is obvious that the shell assembly 100 provided by the present disclosure can better simplify the structure of the piston assembly 2 and facilitate the installation and manufacturing of the piston assembly 2, thereby reducing the production difficulty.

[0054] In addition, in some embodiments, referring to FIGS. 1-13, 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 the 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, so that the gas in the primary compression chamber 111 can be filled into the secondary compression chamber 112 through the third one-way valve 12 via the heat dissipation flow channel 3, but the gas in the secondary compression chamber 112 cannot flow back to the primary compression chamber 111, thereby avoiding the problem of gas backflow.

[0055] It should be noted that the above-mentioned embodiment in which the third one-way valve 12 is arranged at the second communication port 121 is exemplary, and in 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, and the present disclosure is not limited thereto.

[0056] In addition, the one-way valve can be any one-way valve structure known in the art to achieve one-way flow of gas and avoid backflow of gas. The present disclosure does not make further description here, and those skilled in the art can adaptively design according to actual application requirements.

[0057] It should be noted that in the vertical direction, referring to the up-down direction of the drawing plane of FIG. 11, the first compression chamber 111 can be arranged below the second compression chamber 112. Of course, the specific embodiment that the first compression chamber 111 is arranged below the second compression chamber 112 is exemplary. In other embodiments not shown, the first compression chamber 111 can also be arranged above the second compression chamber 112. Alternatively, in other embodiments not shown, the first compression chamber 111 and the second compression chamber 112 can also be arranged apart in the horizontal direction, which can refer to the left-right direction of the drawing plane of FIG. 11. The present disclosure does not make specific limitations on such variations, and those skilled in the art can adaptively design according to actual application requirements. The present disclosure is not limited in this way.

[0058] The present disclosure is exemplarily described with the first compression chamber 111 arranged below the second compression chamber 112:

[0059] In some embodiments, referring to FIGS. 11-13, the heat dissipation flow channel 3 can include a first heat exchange flow channel segment 310 formed outside the housing 1, and the two ends of the first heat exchange flow channel segment 310 are respectively communicated with the first compression chamber 111 and the second compression chamber 112. In this way, by arranging the heat dissipation flow channel 3 outside the housing 1, the gas in the heat dissipation flow channel 3 can be more easily dissipated, ensuring a higher heat dissipation effect, which is conducive to the long-term stable operation of the gas compression device 200.

[0060] Of course, the specific embodiment that the heat dissipation flow channel 3 includes the first heat exchange flow channel segment 310 formed outside the housing 1 is exemplary. In other embodiments, referring to FIGS. 8-10, the heat dissipation flow channel 3 can also include a second heat exchange flow channel segment 320 formed on the housing 1, and the two ends of the second heat exchange flow channel segment 320 are respectively communicated with the first compression chamber 111 and the second compression chamber 112. In this way, by arranging the heat dissipation flow channel 3 outside the containing cavity 110 of the housing 1, on the one hand, the gas in the heat dissipation flow channel 3 can be more easily dissipated, ensuring a higher heat dissipation effect, which is conducive to the long-term stable operation of the gas compression device 200. On the other hand, at least part of the space of the housing 1 can also be directly utilized, and the structure is simpler and has a lower space occupancy. In this way, when the housing assembly 100 is applied to the gas compression device 200, for example, the occupancy of the installation space of the housing assembly 100 can be reduced, and the space utilization can be higher.

[0061] 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 other embodiments not shown, the heat dissipation flow channel 3 can also include the second heat exchange flow channel segment 320 formed on the shell 1 and the first heat exchange flow channel segment 310 formed outside the shell 1, so that, for example, one end of the second heat exchange flow channel segment 320 is communicated with the primary compression chamber 111, the other end is communicated with one end of the first heat exchange flow channel segment 310, and the other end of the first heat exchange flow channel segment 310 is communicated with 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 realize communication with the primary compression chamber 111 and the secondary compression chamber 112 through the heat dissipation flow channel 3.

[0062] In addition, it should be noted that the heat dissipation flow channel 3 can be provided with, for example, a heat dissipation portion (not shown in the figure) outside to realize heat dissipation of the gas in the heat dissipation flow channel 3. The heat dissipation portion can be constructed in any suitable manner, for example, the heat dissipation portion can include a fan to cool the first heat exchange flow channel segment 310 and the second heat exchange flow channel segment 320 through air cooling by blowing, so as to realize cooling of the gas in the heat dissipation flow channel 3, or the heat dissipation portion can include a spray head to cool the first heat exchange flow channel segment 310 and the second heat exchange flow channel segment 320 through water cooling by spraying, or the first heat exchange flow channel segment 310 and / or the second heat exchange flow channel segment 320 can be provided with heat dissipation fins to realize heat dissipation by, for example, external wind power. Of course, air cooling, water cooling or heat dissipation fins can also be used simultaneously, or any other way to cool the first heat exchange flow channel segment 310 and the second heat exchange flow channel segment 320 can also be used to cool and cool the gas in the heat dissipation flow channel 3, which is not limited in the present disclosure.

[0063] In some embodiments, referring to FIGS. 11-13, the shell 1 can include a first shell 120 and a first end cover 130, the first shell 120 and the first end cover 130 together enclosing a containing cavity 110, the first end cover 130 is provided with a first communication port 131, the first shell 120 is provided with a second communication port 121, one end of the heat dissipation flow channel 3 is communicated with the primary compression chamber 111 through the first communication port 131, and the other end of the heat dissipation flow channel 3 is communicated with the secondary compression chamber 112 through the second communication port 121, so as to realize communication with the primary compression chamber 111 and the secondary compression chamber 112 through the heat dissipation flow channel 3. In this way, without modifying the piston assembly 2, the structure of the piston assembly 2 can be simpler, which is convenient for on-site installation and manufacturing, and can reduce the difficulty and cost of on-site production.

[0064] Of course, the specific embodiments of the shell 1 described above are exemplary, in other embodiments, referring to FIG. 4, the shell 1 can also include a first shell 120, a first end cover 130, and a second end cover 140, which together enclose the accommodation cavity 110, the first end cover 130 is provided with a first communication port 131, and the second end cover 140 is provided with a third communication port (not shown), one end of the heat dissipation flow channel 3 is communicated with the primary compression chamber 111 through the first communication port 131, and the other end of the heat dissipation flow channel 3 is communicated with the secondary compression chamber 112 through the third communication port, so as to realize the communication of the heat dissipation flow channel 3 with the primary compression chamber 111 and the secondary compression chamber 112.

[0065] Alternatively, in other embodiments, the shell 1 can also include a first shell 120, which is provided with a fourth communication port (not shown) and a second communication port 121, one end of the heat dissipation flow channel 3 is communicated with the primary compression chamber 111 through the fourth communication port, and the other end of the heat dissipation flow channel 3 is communicated with the secondary compression chamber 112 through the second communication port 121, and 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 of the heat dissipation flow channel 3 with the compression chamber through the communication port on the end cover, and / or the heat dissipation flow channel 3 can also be realized to communicate with the compression chamber through the communication port opened on the outer wall of the first shell 120.

[0066] According to a second aspect of the present disclosure, a gas compression device 200 is provided, referring to FIGS. 11-13, the gas compression device 200 includes the piston assembly 2 and the shell assembly 100 described above, so as to simplify the structure of the piston assembly, facilitate the installation and manufacturing of the piston assembly, reduce the production difficulty, and also facilitate the more stable reciprocating movement of the piston. In addition, the gas compression device 200 also has all the beneficial effects of the shell assembly 100 described above, which will not be repeated here.

[0067] In some embodiments, referring to FIGS. 11-13, the gas compression device 200 can also include a driving assembly 5, which is drivingly connected with the piston assembly 2 to drive the piston 210 of the piston assembly 2 to reciprocate in the vertical direction, and the piston assembly 2 divides the accommodation cavity 110 into the primary compression chamber 111, the first intake chamber 113, and the secondary compression chamber 112 arranged in sequence, which is more simple in structure and facilitates on-site installation and manufacturing.

[0068] It should be noted that in FIG. 11, it is exemplarily shown that during the reciprocating movement of the piston 210 along the vertical direction relative to the first housing 120, the volume change amount of the primary compression chamber 111 is greater than that of the secondary compression chamber 112, so that when the piston 210 moves upward relative to the first housing 120 along the vertical direction, for example, due to the increase in the volume of the primary compression chamber 111, the pressure decreases, which can enable the gas in the first intake chamber 113 to be filled into the primary compression chamber 111, and when the piston 210 moves downward relative to the first housing 120 along the vertical direction, due to the decrease in the volume of the primary compression chamber 111, the gas in the primary compression chamber 111 is compressed once, 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 will be discharged to the secondary compression chamber 112, and as the piston 210 continues to move upward relative to the first housing 120 along the vertical direction, the gas in the secondary compression chamber 112 will be compressed twice to achieve the discharge of the high-pressure gas after secondary compression to the outside of the outer shell 1, for example, to the air spring 400 of the air suspension system 500 of the vehicle 600, thereby improving the comfort, driving performance and passability of the vehicle 600.

In addition, it should be noted that the present disclosure does not make specific limitation on the specific opening size of the first inlet and outlet 6 and the second inlet and outlet 530 and the corresponding arrangement number, and the person skilled in the art can adaptively design according to the actual application requirements.

[0073] In addition, the present disclosure does not make specific limitation on the specific structure of the driving assembly 5, and the person skilled in the art can select the driving motor known in the art as the driving member according to the actual application requirements to realize the driving of the piston assembly 2 through the electric driving, and of course, in other embodiments, the driving of the piston assembly 2 can also be realized through the driving mode such as gas pressure or hydraulic pressure, and the present disclosure does not make specific limitation on this, and the purpose is to realize the reciprocating movement of the piston assembly 2 driven by the driving assembly 5.

[0075] The temperature monitoring member can be configured in any suitable manner, for example, a temperature sensor known in the art can be selected by those skilled in the art to detect the temperature of the gas in the gas compression device 200, and the temperature sensor is signal connected with a controller (not shown) for example, so that the controller can receive the temperature information detected by the temperature sensor, and then targeted effective temperature adjustment measures can be taken to ensure that the gas compression device 200 works stably for a long time.

[0076] It should be noted that the above controller can be a separately arranged controller such as a PLC controller or a single-chip microcomputer, or can be an electronic controller (ECU) of the vehicle 600, and the present disclosure does not make specific limitations thereon, and the above controller can be signal connected with the above execution member such as the temperature sensor in a wireless or wired manner.

In addition, since the outer peripheral wall of the filter element 720 is directly attached to the inner peripheral wall of the second air inlet chamber 711 of the second housing 710, i.e., the filter shell arranged outside the filter element in the related art is cancelled, the number of parts is simplified, which facilitates the lightweight design of the gas supply device 300, and also improves the space utilization of the drying agent in the filter element 720, thereby improving the drying and filtering effect of the high-pressure gas discharged to the air spring 400.

[0082] In addition, as shown in FIG. 11, the filter element 720 can be sleeved on the pressure relief pipe 9, so that not only the pressure relief operation can be realized 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, which has high integration and improves the space utilization.

[0083] In addition, as shown in FIG. 13, the gas inlet port 910 of the pressure relief pipe 9 can communicate with the first chamber 7111, so that when the gas supply device 300 is in, for example, a gas discharge operation, that is, the gas discharged from, for example, the air spring 400 can flow through the filter element 720 in the direction of the arrow in FIG. 13, which can better realize the removal of at least part of the moisture in the desiccant in the filter element 720 and discharge into, for example, the outside atmosphere through the pressure relief pipe 9, which can effectively prolong the service life of the dry filtration assembly 7.

In addition, it should be noted that the pressure relief operation of the pressure relief valve 820 can be to discharge the high-pressure gas in the second air inlet chamber 711 to the first air inlet 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 can be directly connected to the outside atmosphere without being connected to the first air inlet chamber 113, thereby realizing the pressure relief operation, and the present disclosure is not limited thereto.

[0088] Based on the above embodiments, the present disclosure exemplarily describes the inflation, deflation and air release working processes of the air supply device 300, which are as follows:

[0089] a. Inflation of the air supply device 300:

[0090] As shown in Fig. 11, by controlling the electromagnetic valve 830, the third pipeline 16 and the second pipeline 15 are not communicated, at this time, the first one-way valve 810 of the pressure relief valve 820 is in the normally closed state under the action of the spring force F1, that is, the pressure relief valve 820 is not communicated with the second air inlet chamber 711 at this time;

[0091] The driving assembly 5 drives the piston assembly 2 to reciprocate along the vertical direction relative to the first shell 120, when the piston 210 of the piston assembly 2 moves upward along the vertical direction relative to the first shell 120, due to the increase of the volume of the primary compression chamber 111, the pressure decreases, the second one-way valve 11 opens, so that the gas in the first air inlet chamber 113 fills into the primary compression chamber 111 through the second one-way valve 11;

[0092] When the piston 210 moves downward along the vertical direction relative to the first shell 120, due to the decrease of the volume of the primary compression chamber 111, the gas in the primary compression chamber 111 is compressed once, 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, so that the gas in the primary compression chamber 111 is discharged into the secondary compression chamber 112 through the heat dissipation flow channel 3, and the gas can be cooled during the flow through the heat dissipation flow channel 3;

[0093] When the piston 210 continues to move upward along the vertical direction relative to the first shell 120, the gas in the secondary compression chamber 112 is compressed twice, the third one-way valve 12 closes, when the pressure of the gas in the secondary compression chamber 112 reaches the opening value of the fourth one-way valve 13, the fourth one-way valve 13 opens, so that the high-pressure gas after the secondary compression is discharged into the second air inlet chamber 711, and after the drying filtration of the filter element 720, it is discharged to the air spring 400 of the air suspension system 500 of the vehicle 600 through the second pipeline 15, thereby improving the comfort, driving performance and passability of the vehicle 600.

[0094] b, the air supply device 300 is discharged:

[0095] As shown in Fig. 12, when the gas pressure in the second air inlet chamber 711 is too high and exceeds the safety pressure set by the pressure relief valve 820, the force F2 of the high-pressure gas acting 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 is opened, the air supply device 300 starts to discharge, avoiding the occurrence of unexpected situations caused by the too high system pressure, and improving the safety of the system.

[0096] c, the air supply device 300 is discharged:

[0097] As shown in Fig. 13, by controlling the electromagnetic valve 830, the second branch 1620 of the third pipeline 16 is communicated with the second pipeline 15, and at this time the fourth one-way valve 13 is in a closed state, the high-pressure gas from the air spring 400 of the air suspension system 500 of the vehicle 600 is discharged into the second inlet chamber 711 and the pressure relief valve 820, respectively, via the second pipeline 15, at this time the valve core of the pressure relief valve 820 is acted on by the high-pressure gas (F2+F3) which exceeds the spring force F1, that is, (F2+F3) is greater than F1, the spring is compressed, the first one-way valve 810 is opened, and the high-pressure gas from the air spring 400 of the air suspension system 500 of the vehicle 600 can be discharged to the first inlet chamber 113 through the first pipeline 14 and discharged into the external atmosphere via the first inlet and outlet 6;

[0098] And, during the air discharge process of the air supply device 300, since the high-pressure gas discharged from the air spring 400 of the air suspension system 500 of the vehicle 600 can flow through the filter element 720 in the direction of the arrow in Fig. 13, at least part of the moisture in the desiccant in the filter element 720 can be better removed and discharged into the external atmosphere via the pressure relief pipe 9, which can effectively prolong the service life of the drying filter assembly 7.

[0099] During rapid starting, by controlling the electromagnetic valve 830 to open the pressure relief valve 820, the gas with a certain pressure from the gas compression device 200 (for example, from the secondary compression chamber 112) is returned to the first inlet chamber 113 of the gas compression device 200 via the drying filter assembly 7, and then compressed to quickly reach the working pressure, and then the electromagnetic valve 830 is controlled to close the pressure relief valve 820, so that the air supply device 300 can quickly switch to the inflation state.
