For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, directional terms such as above, below, up, down, upward, downward, left, right, etc. are used relative to the exemplary embodiments as shown in the figures, with the upward or upper direction toward the top of the corresponding figure, and the downward or lower direction toward the bottom of the corresponding figure.

[0034] The purpose of the utility model is to provide an integrated air supply module and an air suspension system to solve the problem of unreasonable arrangement of the dryer of the existing air supply module.

[0035] Please refer to Figures 2 to 5 The embodiment of the utility model provides an integrated air supply module, which has x-directions, y-directions and z-directions that are perpendicular to each other. It should be noted that the x-directions, y-directions and z-directions here are virtual directions set for the convenience of description, and are not the actual structures of the integrated air supply module.

[0036] The integrated air supply module includes: a valve body 10, a dryer 20 and a driver 30; a compressor 11 is provided inside the valve body 10, the extension length of the valve body 10 along the x direction is greater than the extension length of the valve body 10 along the y direction, the driver 20 is connected to the valve body 10 along the z direction, and is used to drive the compressor 11 to exhaust air to the dryer 20; the dryer 20 extends along the x direction and is connected to the valve body 10 along the y direction.

[0037] In an alternative exemplary embodiment, the compressor 11 may be, for example, a piston compressor including a plunger pump, which may be disposed in a cavity provided in the valve body 10. The driver 30 may, for example, include a motor, which is disposed on the top surface of the valve body 10 along the z direction and is connected to the compressor 11 via a transmission assembly (such as a crank-connecting rod mechanism, etc.). The motor may drive the piston of the compressor 11 to reciprocate through the transmission assembly, and in conjunction with a number of one-way valves (such as an intake one-way valve, an exhaust one-way valve, etc.), the gas may be compressed and discharged. The specific structure and principle of the driver 30, the transmission assembly and the compressor 11 may refer to the prior art, and the present utility model will not elaborate on this.

[0038] The outside air often contains a certain amount of moisture, which is disadvantageous for the application of the air suspension system, so the exhaust end of the compressor 11 is often connected to the dryer 20 to dry the gas discharged by the compressor 11. The dried gas can be transported to the air storage tank and the air spring.

[0039] In the present embodiment, the outer contour of the valve body 10 is roughly in the shape of a cube, and the extension directions of its sides are arranged along the x-direction, the y-direction and the z-direction respectively. The extension length of the valve body 10 along the x-direction is greater than the extension length along the y-direction, that is, viewed on the xy plane, the side of the valve body 10 along the x-direction is the long side, and the side along the y-direction is the short side. The dryer 20 extends along the x-direction, that is, the dryer 20 extends along the long side direction of the valve body 10. When the spatial volume of the integrated air supply module assembly is constant, the dryer 20 extends along the long side direction of the valve body 10, and a relatively longer gas flow length can be obtained. Furthermore, the dryer 20 is connected to the valve body 10 along the y-direction, for example, the dryer 20 is abutted against and installed on one side of the valve body 10 along the y-direction.

[0040] Such configuration makes the structure distribution of the integrated air supply module assembly more reasonable and compact after assembly, which is conducive to vibration resistance. In addition, since the dryer 20 extends along the x-direction, that is, along the long side of the valve body 10, it is conducive to increasing the length of the dryer 20 in a limited space, thereby increasing the contact time between the gas and the desiccant at the same gas flow rate, thereby improving the drying capacity.

[0041] Please refer to Figure 2 and Figure 3 Preferably, the dryer 20 is detachably connected to the valve body 10 by means of a bolt 12. In one embodiment, the dryer 20 has a bolt hole 21 opened along the y direction, and the valve body 10 is provided with a screw hole at a position corresponding to the bolt hole 21. After the dryer 20 abuts against one side of the valve body 10 along the y direction, the bolt 12 passes through the bolt hole 21 and is screwed into the screw hole, so that the dryer 20 can be fixed on the valve body 10.

[0042] Furthermore, the valve body 10 has a first connection end and a second connection end (not shown), and the interior of the valve body 10 has a ventilation channel (not shown), and the first connection end is connected to the exhaust end of the compressor 11 through the ventilation channel; the dryer 20 has an air inlet 22 and an air outlet 23, the air inlet 22 is connected to the first connection end, and the air outlet 23 is connected to the second connection end. In one embodiment, the air inlet end (referring to the port for connecting with the air inlet end of the compressor 11) and the air outlet end (referring to the port for connecting with the air tank and the air spring) of the entire integrated air supply module are both arranged on the valve body 10, and the air inlet end is connected to the air inlet end of the compressor 11 through the ventilation channel opened inside the valve body 10, and the air outlet end is connected to the second connection end through the ventilation channel opened inside the valve body 10. In this way, the dryer 20 only needs to be provided with an air inlet 22 and an air outlet 23 for docking with the valve body 10, and no other additional air path connection components are required. The gas flow direction of the entire gas circuit is: the air inlet end of the integrated air supply module → the air inlet end of the compressor 11 → the exhaust end of the compressor 11 → the first connection end → the air inlet 22 → the dryer 20 → the air outlet 23 → the second connection end → the air outlet end of the integrated air supply module.

[0043] Optionally, the air inlet 22 and the air outlet 23 both extend along the y-direction, and the outer contours of the air inlet 22 and the air outlet 23 are, for example, cylinders protruding along the y-direction. Correspondingly, the first connecting end and the second connecting end are circular grooves recessed along the y-direction and arranged on the valve body 10. Since the dryer 20 is connected to the valve body 10 along the y-direction, such a configuration can facilitate the assembly and disassembly of the dryer 20 and the valve body 10. Of course, it is understandable that in other embodiments, the air inlet 22 or the air outlet 23 can be configured as a recessed shape, and the corresponding first connecting end or the second connecting end can be configured as a convex column, and those skilled in the art can make adaptive adjustments.

[0044] Preferably, one of the air inlet 22 and the air outlet 23 is configured to be sealed and connected to the corresponding connection end through an end face seal, and the other is configured to be sealed and connected to the corresponding connection end through a radial seal. In an alternative exemplary embodiment, the air inlet 22 is configured to be sealed and connected to the first connection end through an end face seal, and the air outlet 23 is configured to be sealed and connected to the second connection end through a radial seal. End face sealing refers to a sealing component (such as an elastic sealing ring) being arranged on the end faces of two corresponding connection parts to achieve sealing. For example, if the air inlet 22 is a cylinder protruding along the y direction, the axial end face of the cylinder is pressed and connected with the bottom face of the circular groove of the corresponding first connection end through a sealing component, thereby achieving end face sealing. Radial sealing refers to a sealing component being arranged on the radial faces of two corresponding connection parts to achieve sealing. For example, if the air outlet 23 is a cylinder protruding along the y direction, the radial surface of the cylinder (i.e. the outer circumferential surface of the cylinder) is pressed against the inner wall of the circular groove of the corresponding second connecting end through a sealing component, thereby achieving radial sealing.

[0045] It is understandable that the end face seal has a higher sealing accuracy requirement in the y direction, but allows a certain error in the x and z directions; while the radial seal has a higher sealing accuracy requirement in the x and z directions, but allows a certain error in the y direction. The air inlet 22 and the air outlet 23 are selected in different sealing modes and used in combination, which relaxes the positioning requirements and reduces the processing accuracy requirements of the dryer 20 and the valve body 10.

[0046] Please refer to Figures 2 to 4 Optionally, the dryer 20 includes at least two drying cylinders 24 extending along the x-direction; the drying cylinder 24 has an inner cavity 240, and the inner cavity 240 preferably extends along the x-direction. A desiccant 25 is accommodated in the inner cavity 240, and the drying cylinder 24 is used to allow gas to flow through the desiccant 25 along its own axial direction (i.e., the x-direction). The parallel arrangement of two or more drying cylinders 24 is beneficial to the uniform distribution of flow velocity during gas circulation, reduces dead volume, and thus improves the effective utilization rate of the desiccant 25. Considering the size of the drying cylinder 24 and the spatial volume of the entire integrated air supply module assembly, the number of drying cylinders 24 is preferably two or three. Please refer to Figure 4 , which shows a cross section of a dryer 20 including two drying cylinders 24 along the xz direction, wherein the air inlet 22 and the air outlet 23 are arranged in the middle of the two drying cylinders 24.

[0047] Please refer to Figure 4 and Figure 5Preferably, each drying cylinder 24 includes a spring 26 and two vent press pieces 27; the two vent press pieces 27 are arranged in the inner cavity 240 at intervals along the axial direction of the inner cavity 240, and divide the inner cavity 240 into a first zone 241, a second zone 242 and a third zone 243; the first zone 241 is connected to the air inlet 22 of the dryer 20, the desiccant 25 is accommodated in the second zone 242, and the third zone 243 is connected to the air outlet 23 of the dryer 20; the spring 26 is arranged in the first zone 241 along the axial direction of the inner cavity 240, one end of the spring 26 is connected to the end wall of the inner cavity 240, and the other end is connected to the vent press piece 27 close to the first zone 241, and is used to apply pressure to the vent press piece 27 close to the first zone 241. The spring 26 can be used to provide a pre-tightening force (such as pressure) to the vent pressing piece 27 to compact the desiccant 25 accommodated between the two vent pressing pieces 27 and reduce the wear of the desiccant 25 .

[0048] Optionally, the ventilation compression piece 27 includes a perforated plate 271 and a filter disc 272, and the perforated plate 271 and the filter disc 272 are arranged in an axially overlapping manner along the inner cavity 240, and the filter disc 272 is located on the side facing the second zone 242. The perforated plate 271 is preferably evenly provided with a plurality of through holes so that the airflow flows evenly through the desiccant 25. The filter disc 272 is used to filter the gas flowing through, thereby preventing the dust of the desiccant 25 from flowing out and the external particles from entering. It can be understood that the filter disc 272 is located on the side facing the second zone 242, that is, the two ventilation compression pieces 27 are arranged in the direction in which the filter discs 272 face each other. One end of the spring 26 abuts against the end wall of the inner cavity 240, and the other end abuts against the perforated plate 271 adjacent to the first zone 241. The flow direction of the gas in the dryer 20 can be referred to. Figure 4 As shown by arrow F in the middle.

[0049] Preferably, the dryer 20 further comprises a stopper 28, which is connected to the orifice plate 271 near the first zone 241 along the circumference of the orifice plate 271; the stopper 28 is used to abut against the side wall of the inner cavity 240 to limit the orifice plate 271 from tilting in the inner cavity 240. In an alternative exemplary embodiment, the orifice plate 271 is substantially a circular plate, preferably perpendicular to the axial direction of the inner cavity 240, and the orifice plate 271 adjacent to the first zone 241 is used to compress the desiccant 25 under the pressure of the spring 26. However, since the desiccant 25 is generally in the form of loose particles or powder, the orifice plate 271 may have the risk of tilting (the orifice plate 271 is not perpendicular to the axial direction of the inner cavity 240 and forms an angle), resulting in uneven preload of the spring 26, or the desiccant 25 falling out of the second zone 242. The setting of the limiting piece 28 limits the orifice plate 271 to move only along the axial direction of the inner cavity 240, thereby avoiding the occurrence of tilting and preventing the risk of uneven preload force of the spring 26 caused by the tilting of the orifice plate 271 during use.

[0050] Please refer to Figure 2and Figure 3 Optionally, the dryer 20 includes a plurality of reinforcing ribs 291, which are arranged between at least two drying cylinders 24 along the axial direction (i.e., the x-direction) of the drying cylinder 24 and are respectively connected to at least two drying cylinders 24. The reinforcing ribs 291 may extend along the yz plane, i.e., perpendicular to the axial direction of the drying cylinder 24. The plurality of reinforcing ribs 291 are arranged at intervals along the x-direction, which effectively improves the mechanical strength of the dryer 20.

[0051] Optionally, the dryer 20 includes a plurality of support platforms 292, one end of the support platform 292 is connected to the drying cylinder 24, and the other end is against the valve body 10. The support platforms 292 are preferably arranged on both sides of the reinforcing rib 291, and are used to fit with the side of the valve body 10 to limit the relative position of the dryer 20 and the valve body 10 along the y direction. Figure 3 In the illustrated example, the number of the support platforms 292 is 4. It is understandable that in other embodiments, the number of the support platforms 292 is not limited to 4, but may be more or less, such as 6.

[0052] Optionally, the integrated air supply module further includes a controller 40, which is preferably disposed along the z-direction on a side of the valve body 10 relative to the driver 30. The controller 40 is provided with circuit components, etc., which can be used to control the operation of the driver 30, etc. The specific structure of the circuit components can be referred to the prior art, and will not be described in detail in this embodiment.

[0053] Based on the above integrated air supply module, the embodiment of the utility model also provides an air suspension system, which includes the above integrated air supply module, and optionally also includes air springs, shock absorbers, guide mechanisms, sensors, air tanks and other components. The structure and principle of these components can refer to the prior art, and will not be described in detail in this embodiment.

[0054] In summary, in the integrated air supply module and air suspension system provided by the utility model, the integrated air supply module has x-direction, y-direction and z-direction which are mutually perpendicular in pairs, and the integrated air supply module includes: a valve body, a dryer and a driver; a compressor is provided inside the valve body, the extension length of the valve body along the x-direction is greater than the extension length of the valve body along the y-direction, the driver is connected to the valve body along the z-direction, and is used to drive the compressor to exhaust air to the dryer; the dryer extends along the x-direction and is connected to the valve body along the y-direction. In such a configuration, since the extension length of the valve body along the x-direction is greater than the extension length along the y-direction, and the dryer is connected to the valve body along the y-direction, it can be understood that the dryer is arranged on one side of the long side of the valve body, so that the structural distribution of the integrated air supply module assembly after assembly is more reasonable and compact, which is conducive to vibration resistance. In addition, since the dryer extends along the x-direction, that is, along the long side of the valve body, it is conducive to increasing the length of the dryer in a limited space, thereby increasing the contact time between the gas and the desiccant at the same gas flow rate, thereby improving the drying capacity.

[0055] It should be noted that the above embodiments can be combined with each other. The above description is only a description of the preferred embodiments of the utility model, and does not limit the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure are within the protection scope of the utility model.
