[0002] With the rapid development of the automobile industry, people have higher and higher demands for the comfort and driving stability of automobiles. Air springs can adjust the height according to different road conditions, so as to better adapt to road conditions and user needs.

[0004] Therefore, there is an urgent need to provide an air supply module and an air spring to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0008] Specifically, the control assembly further includes a control board, and the control board is connected to the plurality of control valves and the drive component lines.

[0009] Furthermore, a positioning groove is formed on one end surface of the pneumatic block facing the compressor assembly or on one end surface of the compressor assembly facing the pneumatic block, the shape of the positioning groove is adapted to the seal, and the depth of the positioning groove is less than the thickness of the seal.

[0010] Furthermore, the compressor assembly includes a shell and a compressor body, the pneumatic block and the shell are both made of metal material or the shell is made of metal material, and the pneumatic block is made of plastic material and is formed by injection molding.

[0012] Specifically, the air supply module provided by the utility model also includes an air storage tank, which is connected to the side of the compressor assembly away from the pneumatic block, and the air storage tank forms an air storage space, which is connected to the connecting air channel of the compressor assembly, and the driving component is located in the air storage space.

[0013] Furthermore, the air supply module provided by the utility model also includes a dryer, a bearing cavity is formed in the pneumatic block, the bearing cavity is connected with the air passage in the pneumatic block, the dryer is arranged in the bearing cavity, and the air outlet of the compressor assembly is correspondingly connected with the bearing cavity.

[0014] Furthermore, the air supply module provided by the utility model also includes a dryer, a first connecting pipe and a second connecting pipe. The dryer is located outside the pneumatic block, one end of the first connecting pipe is connected to the air outlet end of the pneumatic block, and the other end is connected to the air inlet end of the dryer, and one end of the second connecting pipe is connected to the air outlet end of the dryer, and the other end is connected to the air inlet end of the pneumatic block.

[0018] It can be understood that since the gas required by the air supply module needs to be compressed by the compressor assembly and then supplied to the pneumatic block and then distributed through the pneumatic block, and the pneumatic block and the compressor assembly in the present application are split structures, therefore, by providing a seal between the pneumatic block and the compressor assembly, the air tightness between the two can be increased to avoid leakage of compressed gas and ensure the function of the overall air supply module and the air spring using the air supply module.

[0038] like Figure 1 As shown, the utility model provides an air supply module, including an air supply mechanism and a driving component 3; the air supply mechanism includes a pneumatic block 1, a compressor assembly 2 and a sealing member 4, the ventilation end of the pneumatic block 1 is connected to the ventilation end of the compressor assembly 2, the sealing member 4 is located between the pneumatic block 1 and the compressor assembly 2, and the pneumatic block 1 and the compressor assembly 2 are detachably connected; the driving component 3 is connected to the input end of the compressor assembly 2 to drive the compressor assembly 2 to form high-pressure gas to enter the pneumatic block 1.

[0039] Compared with the prior art, the air supply module provided by the utility model has the following advantages:

[0040] The air supply module provided by the utility model can realize the separate manufacturing of the pneumatic block 1 and the compressor assembly 2 by making the pneumatic block 1 and the compressor assembly 2 detachable and connected. Since a plurality of air passages interconnected with each other are formed in the pneumatic block 1, and the plurality of air passages need to be formed by drilling during processing, therefore, by processing and manufacturing the pneumatic block 1 separately, the operable processing surface of the pneumatic block 1 can be increased during the drilling of the air passage, that is, at least one side where the original pneumatic block 1 is connected to the compressor assembly 2 can be exposed during processing, thereby making the processing of the air passage more flexible and greatly reducing the processing difficulty. Moreover, during processing, interference of the compressor assembly 2 with the processing process of the pneumatic block 1 is avoided. At the same time, the problem of damage to the compressor assembly 2 during processing of the pneumatic block 1 can also be avoided.

[0041] It can be understood that since the gas required by the air supply module needs to be compressed by the compressor assembly 2 and then supplied to the pneumatic block 1, and then distributed through the pneumatic block 1, and the pneumatic block 1 and the compressor assembly 2 in the present application are split structures, therefore, by setting a seal 4 between the pneumatic block 1 and the compressor assembly 2, the air tightness between the two can be increased, the leakage of compressed gas can be avoided, and the stability of the use of the overall air supply module and the air spring using the air supply module can be ensured.

[0042] Accordingly, the driving component 3 connected to the compressor assembly 2 can provide drive for the operation of the compressor assembly 2 to ensure the stable operation of the overall structure.

[0043] Alternatively, if Figure 1-Figure 3 As shown, the air supply module provided by the utility model also includes a control component. The pneumatic block 1 is formed with a plurality of air passages. The end face of the pneumatic block 1 is formed with a plurality of mounting holes 101 connected to the air passages. The control component includes a plurality of control valves 5. The plurality of control valves 5 are arranged in a one-to-one correspondence with the mounting holes 101, and the control valves 5 can control the connection or blocking between the plurality of air passages through the mounting holes 101.

[0044] Preferably, if Figure 1 As shown, in order to ensure the adjustment of the air spring under different working conditions, the number of mounting holes 101 formed on the pneumatic block 1 in the present application is 9, and correspondingly, the number of control valves 5 is also 9, so that the adjustment of the air spring under different working conditions can be achieved by adjusting the opening or closing of the control valve 5.

[0045] It should be noted here that, preferably, the control valve 5 in the present application has only two adjustment modes: opening and closing, that is, the air passage has only two forms: connected or blocked, which can make the control process simpler and reduce the difficulty of designing the control logic.

[0046] Accordingly, if Figure 1-Figure 3 As shown, the control assembly in the present application further includes a control board 6 , and the control board 6 is connected to the plurality of control valves 5 and the drive member 3 through lines.

[0047] The control board 6 in the present application can be a PCB board, and the control valve 5 can be a solenoid valve. By connecting the lines of multiple control valves 5 to the control board 6, the control board 6 can be used to achieve the purpose of switching on and off different control valves 5, thereby achieving the adjustment of different working conditions of the overall air spring.

[0048] Optionally, a positioning groove is formed on one end surface of the pneumatic block 1 facing the compressor assembly 2 or one end surface of the compressor assembly 2 facing the pneumatic block 1 in the present application, the shape of the positioning groove is adapted to the seal 4, and the depth of the positioning groove is less than the thickness of the seal 4.

[0049] The present application forms a positioning groove on one end face of the pneumatic block 1 facing the compressor assembly 2 or on one end face of the compressor assembly 2 facing the pneumatic block 1, so as to realize the positioning of the seal 4. In addition, since the depth of the positioning groove in the present application is less than the thickness of the seal 4, when the seal 4 is embedded in the positioning groove, a part of it can protrude from the positioning groove, so that when the pneumatic block 1 and the compressor assembly 2 are connected, the part of the seal 4 protruding from the positioning groove can be squeezed, thereby improving the sealing performance between the pneumatic block 1 and the compressor assembly 2 to a certain extent.

[0050] Preferably, the positioning groove in the present application is formed on one side end face of the pneumatic block 1 facing the compressor assembly 2. Since the pneumatic block 1 and the compressor assembly 2 in the present application are split structures, and the pneumatic block 1 needs to be processed with structures such as the gas channel, therefore, by forming the positioning groove on the pneumatic block 1, the positioning groove can be processed at the same time as the gas channel and other structures are processed, thereby making the distribution of processing operations more reasonable.

[0051] Alternatively, if Figure 1-Figure 3As shown, the compressor assembly 2 in the present application includes a shell 201 and a compressor body, the pneumatic block 1 and the shell 201 are both made of metal material or the shell 201 is made of metal material, the pneumatic block 1 is made of plastic material, and is formed by injection molding.

[0052] It can be understood that the shell 201 in the present application is formed with structures such as a accommodating chamber and a connecting air channel. The compressor body is arranged in the accommodating chamber and can compress the gas entering the accommodating chamber. There are multiple connecting air channels, which respectively connect the accommodating chamber and the outside, so as to realize the process in which the gas enters the accommodating chamber from the outside, is compressed by the compressor body, and then flows to the outside of the compressor assembly 2.

[0053] It should be noted here that since the compressor assembly 2 needs to output high-pressure gas, preferably, the outer shell in the present application is made of metal material, mainly the outer shell 201 is made of aluminum material, but it can also be made of other metal materials such as steel, and the material of the compressor body is selected according to the manufacturing requirements of the structure corresponding to the compressed gas part of the existing compressor, which will not be repeated here.

[0054] It should be further explained here that the pneumatic block 1 in the present application can be made of aluminum, but preferably, it is made of plastic material and formed by injection molding. The use of plastic material can reduce production costs and the weight of the overall air supply module on the one hand, and on the other hand, during the injection molding process, especially during the injection molding of the air passage in the pneumatic block 1, the air passage can be formed by directly placing an isolation tube and pulling it out after molding. Since the specifications of the molds and isolation tubes used for injection molding are unified, it can not only reduce processing costs, but also greatly improve processing accuracy and processing efficiency.

[0055] Optionally, the air supply module provided by the utility model also includes a connecting piece, a first connecting part 103 is formed on the pneumatic block 1, a second connecting part 2011 is formed at a position of the compressor assembly 2 corresponding to the first connecting part 103, and the connecting piece passes through the first connecting part 103 and the second connecting part 2011 to connect the first connecting part 103 with the second connecting part 2011.

[0056] The number of the first connection parts 103 in the present application is multiple, and the multiple first connection parts 103 are evenly distributed along the circumference of the pneumatic block 1, the second connection parts 2011 are arranged one by one corresponding to the first connection parts 103, and the connecting parts can adopt fasteners such as bolts to realize the connection between the first connection part 103 and the second connection part 2011, thereby enabling rapid disassembly and assembly between the pneumatic block 1 and the compressor assembly 2.

[0057] It should be noted that the connection member in the present application is not limited to structures such as bolts, and rivets can also be used to connect the two by riveting. Accordingly, a clamping member can be further used to clamp the first connection part 103 and the second connection part 2011 by the clamping member to achieve a detachable connection between the pneumatic block 1 and the compressor assembly 2.

[0058] Alternatively, if Figure 4 As shown, the air supply module provided by the utility model also includes an air storage tank 7, which is connected to the side of the compressor assembly 2 away from the pneumatic block 1, and the air storage tank 7 forms an air storage space, which is connected to the connecting air channel of the compressor assembly 2, and the driving component 3 is located in the air storage space.

[0059] By setting up an air storage tank 7 connected to the compressor assembly 2, and the compressor assembly 2 is also connected to the pneumatic block 1, and the pneumatic block 1 is connected to the main spring body through a connecting pipe, therefore, the air storage tank 7 can provide a stable air source for the main spring body, and accordingly, the gas discharged from the main spring body can also flow back into the air storage tank 7 through the compressor assembly 2 and the pneumatic block 1, thereby ensuring a stable supply of air source to a certain extent and improving the stability of the overall air spring use.

[0060] Since the air flowing in the air supply module needs to be dried to avoid the damp air affecting the service life of the air supply module or even the entire air spring. Figure 2 As shown, an embodiment of providing a dryer 8 in an air supply module is provided. Specifically, a bearing cavity 102 is formed in the pneumatic block 1, the bearing cavity 102 is connected with an air passage in the pneumatic block 1, the dryer 8 is arranged in the bearing cavity 102, and the air outlet of the compressor assembly 2 is correspondingly connected with the bearing cavity 102.

[0061] like Figure 1 Combination Figure 2 As shown, in this embodiment, two bearing cavities 102 are formed in the pneumatic block 1 in the present application. Correspondingly, the number of dryers 8 is two, and they are respectively arranged in the two bearing cavities 102. The air outlet of the compressor assembly 2 is arranged one-to-one with the bearing cavity 102 and is connected to each other.

[0062] When the gas in the air tank 7 needs to enter the air spring, the gas in the air tank 7 first enters the compressor assembly 2. After being compressed by the compressor assembly 2, the high-pressure gas enters the bearing cavity 102 from the air outlet, and after being dried by the dryer 8 in the bearing cavity 102, it flows to the corresponding air passage in the pneumatic block 1, and enters the main spring body through the air port of the pneumatic block 1.

[0063] When the gas in the main spring body needs to flow back into the gas storage tank 7, it first enters the compressor assembly 2 through the gas passage of the pneumatic block 1. Figure 1 As shown, the pneumatic block 1 in the present application is also formed with an air outlet 104 connected to the air passage on the side facing the compressor assembly 2, through which the return gas can be introduced into the compressor assembly 2, and after being compressed by the compressor assembly 2, enters the bearing cavity 102 of the pneumatic block 1, is dried by the dryer 8, and after drying, flows to the air passage in the corresponding pneumatic block 1, and enters the air storage tank 7 through the air port of the pneumatic block 1, thereby realizing the reflux of the gas.

[0064] Accordingly, with the use of the air spring, there will be a certain degree of air shortage. Therefore, the pneumatic block 1 in the present application is also formed with an air guide channel connected to the external environment, and the air guide channel is connected to the above-mentioned air outlet 104, and can be connected and disconnected with the air outlet 104 through the above-mentioned control valve 5. When air needs to be replenished, the air enters the pneumatic block 1 through the air guide channel, and enters the compressor assembly 2 through the air outlet 104. After being compressed by the compressor assembly 2, it enters the bearing cavity 102 of the pneumatic block 1, is dried by the dryer 8, and can enter the air spring or the air storage tank 7 after drying.

[0065] The present application also provides another arrangement of the dryer 8, such as Figure 3 As shown, in this embodiment, the air supply module also includes a dryer 8, a first connecting pipe 9 and a second connecting pipe 10. The dryer 8 is located outside the pneumatic block 1. One end of the first connecting pipe 9 is connected to the air outlet end of the pneumatic block 1, and the other end is connected to the air inlet end of the dryer 8. One end of the second connecting pipe 10 is connected to the air outlet end of the dryer 8, and the other end is connected to the air inlet end of the pneumatic block 1.

[0066] The dryer 8 is arranged outside the pneumatic block 1 through the first connecting pipe 9 and the second connecting pipe 10. On the one hand, it can reduce the processing of the pneumatic block 1, that is, there is no need to form a accommodating cavity. On the other hand, when the dryer 8 is damaged or the drying effect cannot meet the standard, it can be directly disassembled and replaced, thereby improving the working efficiency and reducing the working difficulty.

[0067] It should be noted that, in this embodiment, the dryer 8 is arranged outside the pneumatic block 1 through the first connecting pipe 9 and the second connecting pipe 10, and the gas flow direction and action process are the same as those in the first embodiment, which will not be repeated here.

[0068] It needs to be further explained here that, based on the structure of the above-mentioned pneumatic block 1, since the pneumatic block 1 in the present application is formed with two bearing cavities 102 and two air outlets 104, and there is gas flow in both the bearing cavities 102 and the air outlets 104, therefore, the seal 4 in the present application is correspondingly formed with four annular sealing structures, so that the positions of the air outlets 104 and the bearing cavities 102 can be sealed to ensure the air tightness of the structure.

[0069] Correspondingly, reinforcing ribs 401 are connected between the four ring-mounted seals in the seal 4 of the present application, so that the four ring-mounted seals can form an integral structure through the reinforcing ribs 401, thereby ensuring the structural strength and service life of the seal 4.

[0070] In addition, the utility model also provides an air spring, comprising a main spring body, a connecting pipe and the above-mentioned air supply module, wherein the main spring body is connected to the pneumatic block 1 of the air supply module through the connecting pipe.

[0071] The main spring body is connected to the pneumatic block 1 through a connecting pipe, and the pneumatic block 1 can be used to inject gas into the main spring body or the gas in the main spring body can flow out of the pneumatic block 1, thereby ensuring the function of the overall air spring.

[0072] Since the air spring provided in the present application adopts the air supply module provided in the present application, the disassembly process of each structure can be more convenient during the later maintenance process, which can improve the efficiency of later maintenance to a certain extent and reduce the difficulty of maintenance and inspection.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
