Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to an integrated filter muffler, an air compressor, and a vehicle. Background Technology

[0002] In modern passenger vehicles, air suspension systems are widely used because they provide better ride comfort and vehicle stability. One of the core components of an air suspension system is the air compressor, which is responsible for generating compressed air to adjust the suspension stiffness and vehicle height.

[0003] However, air compressors need to draw in clean air during operation and generate noise. To ensure the cleanliness of the compressed air and reduce noise, a separate filter is usually installed at the input end of the air compressor and a separate silencer is installed at the output end.

[0004] While the separate design of the filter and muffler can achieve the required functions, it also has the following disadvantages: First, the separate design results in more piping connections, occupies more space, and is difficult to adapt to the compact layout of passenger cars; second, since the filter and muffler are independent components, their maintenance and replacement need to be carried out separately, increasing maintenance costs and operational complexity; third, because the muffler is located far from the exhaust port of the air compressor, its suppression effect on high-frequency airflow noise is limited, affecting the noise, vibration, and acoustic harshness (NVH) performance of the vehicle interior. Utility Model Content

[0005] In view of this, the present invention provides an integrated filter muffler, air compressor and vehicle to solve the problems of multiple pipeline connections, large space occupation and difficulty in replacement caused by the separate setting of filter and muffler.

[0006] In a first aspect, this utility model provides an integrated filter silencer, suitable for connection with the compressor body, the integrated filter silencer comprising:

[0007] The filter unit housing and the silencer unit housing are integrated; the filter unit housing contains a filter module, and the silencer unit housing contains a silencer component.

[0008] The filter unit housing has a filter outlet connector at one end that is suitable for connecting to the air inlet of the compressor body, and a filter inlet connector at the other end; the silencer unit housing has a silencer inlet connector at one end that is suitable for connecting to the air outlet of the compressor body.

[0009] The filter outlet connector and the silencer inlet connector are located on the same side of the integrated filter silencer.

[0010] Beneficial effects: The integrated filter silencer provided in this embodiment integrates the filter unit housing and the silencer unit housing. This integration avoids the space occupation and complex connection problems associated with separate installations, reduces the number of pipe connections, effectively decreases the space occupied by the equipment, and improves the overall structural compactness. Furthermore, the integrated design eliminates the need for separate replacement of the filter element and the silencer assembly, simplifying operation and improving maintenance efficiency.

[0011] In one optional embodiment, the muffler unit housing has at least one muffler exhaust port, which is located on the opposite side of the muffler intake connector.

[0012] Beneficial effects: The presence of the silencer exhaust vents ensures smooth airflow. Located on the opposite side of the silencer intake connector, the exhaust vents allow airflow to fully pass through the silencer components inside the silencer unit housing, further absorbing sound wave energy and enhancing noise reduction.

[0013] In one alternative embodiment, the filter unit housing and the silencer unit housing are integrally formed; the integrated filter silencer further includes a mounting base, which is connected to the filter unit housing and / or the silencer unit housing for fixing the integrated filter silencer.

[0014] Beneficial effects: The one-piece molding design not only reduces the number of parts and lowers production costs, but also improves overall sealing performance, preventing gas leakage and further enhancing the reliability and service life of the filter silencer. The mounting bracket ensures a secure installation of the integrated filter silencer.

[0015] In one alternative embodiment, the integrated filter silencer further includes a reinforcing rib connected between the filter unit housing and the silencer unit housing.

[0016] Beneficial effects: By setting reinforcing ribs between the filter unit housing and the silencer unit housing, not only is the overall rigidity of the housing structure enhanced and deformation prevented, but external impact forces can also be effectively dispersed, further improving the vibration resistance and durability of the equipment.

[0017] In one optional embodiment, the integrated filter silencer further includes: a filter unit housing cover, which is detachably connected to the filter unit housing; the filter unit housing cover and the filter unit housing together enclose a filter cavity, and the filter module is placed inside the filter cavity.

[0018] Beneficial effects: The filter unit cover and filter unit housing are detachably connected, which facilitates the regular replacement of the filter module and ensures that the filtration effect remains effective.

[0019] In one optional embodiment, the filter unit cover and the filter unit housing are provided with a buckle on one side and a slot on the other side, and the buckle and the slot are connected in a cooperative manner.

[0020] Beneficial effects: This facilitates quick assembly and disassembly, improving maintenance convenience.

[0021] In one alternative implementation, the noise reduction assembly includes:

[0022] sound-absorbing materials;

[0023] The inner shell is partially connected to form a variable diameter pipe. The inner shell and the inner wall of the silencing unit shell together form a Helmholtz resonant cavity. The inner shell is connected to form a through hole, which is suitable for connecting the Helmholtz resonant cavity to the variable diameter pipe.

[0024] Beneficial effects: The sound-absorbing material forms a resistive noise-absorbing section, effectively absorbing high-frequency noise. The variable-diameter pipe and the Helmholtz resonant cavity together form a reactive noise-absorbing section. Through the resonance effect of the Helmholtz resonant cavity, mid- and low-frequency noise is further reduced, achieving effective noise control across the entire frequency range.

[0025] In one alternative embodiment, the noise reduction component further includes a perforated screen with a plurality of through holes, which is disposed between the sound-absorbing material and the inner shell.

[0026] Beneficial effects: By placing the perforated screen between the sound-absorbing material and the inner shell, sound waves are scattered in the perforations of the perforated screen, further improving the sound absorption effect, ensuring multi-level noise attenuation, and enhancing the overall noise reduction performance.

[0027] Secondly, this utility model also provides an air compressor, comprising:

[0028] The compressor body, and the integrated filter silencer as described above;

[0029] The air inlet and outlet of the compressor body are located on the same side. The air inlet of the compressor body is suitable for being connected to the filter outlet connector via a pipe, and the air outlet of the compressor body is suitable for being connected to the silencer inlet connector via another pipe.

[0030] Beneficial effects: The air inlet and outlet of the compressor body are located on the same side, which allows the integrated filter silencer to be located on one side of the compressor body, simplifying the pipeline layout, reducing installation space, and improving the overall compactness and ease of maintenance of the equipment.

[0031] Thirdly, this utility model also provides a vehicle, comprising:

[0032] An air suspension system, which includes an air compressor as described above.

[0033] Since the vehicle includes an integrated filter muffler, which has the same effect as an integrated filter muffler, it will not be elaborated on here. Attached Figure Description

[0045] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0046] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0047] According to an embodiment of the present invention, an integrated filter silencer is provided, suitable for connection to a compressor body. The integrated filter silencer includes:

[0048] The filter unit housing 10 and the silencer unit housing 20 are integrated together; the filter unit housing 10 has a filter module inside, and the silencer unit housing 20 has a silencer component 24 inside.

[0049] The filter unit housing 10 has a filter outlet connector 11 at one end, which is suitable for connecting with the air inlet of the compressor body, and a filter inlet connector 12 at the other end; the silencer unit housing 20 has a silencer inlet connector 21 at one end, which is suitable for connecting with the air outlet of the compressor body.

[0050] The filter outlet connector 11 and the silencer inlet connector 21 are located on the same side of the integrated filter silencer.

[0051] The integrated filter silencer provided in this embodiment integrates the filter unit housing 10 and the silencer unit housing 20. This integration avoids the space occupation and complex connection problems associated with separate installations, minimizes the need for multiple pipeline connections, effectively reduces equipment space requirements, and improves the overall structural compactness. Furthermore, the integrated design eliminates the need for separate replacement of the filter element and silencer assembly, simplifying operation and improving maintenance efficiency.

[0052] In this embodiment, one end of the filter unit housing 10 is provided with a filter outlet connector 11 suitable for communication with the air inlet of the compressor body, and the other end is provided with a filter inlet connector 12; one end of the silencer unit housing 20 is provided with a silencer inlet connector 21 suitable for communication with the air outlet of the compressor body; the filter outlet connector 11 and the silencer inlet connector 21 are located on the same side of the integrated filter silencer. This ensures that the integrated filter silencer is located on one side of the compressor body, that is, both the filter unit housing 10 and the silencer unit housing 20 are located on the same side of the compressor body, facilitating installation and maintenance, reducing pipeline length, lowering airflow resistance, and improving the overall operating efficiency of the compressor. This not only optimizes the airflow path but also, through a compact structural layout, avoids the situation where the silencer is placed too far away, further reducing noise.

[0053] Additionally, a filter inlet connector 12 is provided at the other end of the filter unit housing 10. The filter inlet connector 12 is connected to an external air intake pipe, ensuring that the airflow first passes through the filter module to purify the compressor intake airflow before entering the compressor body. Finally, after the gas is discharged from the compressor body, it passes through the noise reduction component 24 for noise reduction, ensuring the purity and quietness of the output airflow. This reduces noise, ensures the NVH performance of the vehicle interior, and improves the driving comfort of the vehicle.

[0054] In some embodiments, the filter unit housing 10 and the silencer unit housing 20 are integrally formed. For example, using high-strength engineering plastics, the filter unit housing 10 and the silencer unit housing 20 can be integrally injection molded. This integral design not only reduces the number of parts and lowers production costs, but also improves overall sealing performance, avoids gas leakage problems, and further enhances the reliability and service life of the filter silencer. In addition, the integral design simplifies the assembly process, reduces assembly errors, and improves production efficiency.

[0055] Additionally, the filter unit housing 10 and the silencer unit housing 20 can be connected by welding to ensure connection strength.

[0056] This embodiment uses an integrated housing, which reduces the overall volume by approximately 25% compared to the traditional split design, significantly improving the ease of installation and space utilization. Simultaneously, by optimizing the airflow path, the pipe length can be reduced by approximately 450mm, facilitating vehicle space layout, further reducing connection complexity, avoiding numerous pipe connections, and effectively minimizing the space occupied by the equipment.

[0057] In some embodiments, the muffler housing 20 has at least one muffler exhaust port 22, which is located on the opposite side of the muffler intake connector 21.

[0058] The opening of the silencer vent 22 ensures that the airflow is discharged smoothly.

[0059] Combination Figure 1 As shown, in this embodiment, the silencing unit housing 20 can be constructed as a cylinder, and multiple silencing exhaust holes 22 are opened around the circumference of the cylindrical housing to form a multi-channel exhaust structure, which effectively disperses the airflow and enhances the silencing effect. In addition, the uniform distribution of the silencing exhaust holes 22 around the circumference of the cylindrical housing also helps to reduce the local airflow velocity, reduce airflow turbulence, and further improve the silencing effect.

[0060] The silencer exhaust port 22 is located on the opposite side of the silencer intake connector 21, so that the airflow can fully pass through the silencer component 24 inside the silencer unit housing 20, further absorbing sound wave energy and improving the noise reduction effect.

[0061] In some embodiments, the integrated filter silencer further includes a mounting base 30, which is connected to the filter unit housing 10 and / or the silencer unit housing 20 for fixing the integrated filter silencer.

[0062] The mounting base 30 can be a nut with bolt holes, so that it can be connected to the vehicle body or other components by bolts, ensuring the stable installation of the integrated filter muffler.

[0063] In some embodiments, the integrated filter silencer further includes a reinforcing rib 40 connected between the filter unit housing 10 and the silencer unit housing 20.

[0064] By setting reinforcing ribs 40 between the filter unit housing 10 and the silencer unit housing 20, not only is the overall rigidity of the housing structure enhanced and deformation prevented, but external impact forces are also effectively dispersed, further improving the vibration resistance and durability of the equipment. Multiple reinforcing ribs 40 can be evenly distributed at the connection between the filter unit housing 10 and the silencer unit housing 20, further enhancing the structural stability of the integrated filter silencer.

[0065] In some embodiments, the integrated filter silencer further includes: a filter unit cover 13, which is detachably connected to the filter unit housing 10; the filter unit cover 13 and the filter unit housing 10 together enclose a filter cavity 14, and the filter module is placed inside the filter cavity 14.

[0066] The filter unit cover 13 is detachably connected to the filter unit housing 10, for example by a snap or thread connection, which facilitates the periodic replacement of the filter module and ensures that the filtration effect remains effective.

[0067] Additionally, a sealing gasket is provided at the contact point between the filter unit cover 13 and the filter unit housing 10 to prevent gas leakage, ensure the internal sealing of the filter chamber 14, and further improve the filtration effect and overall operating efficiency.

[0068] In some embodiments, one of the filter unit cover 13 and the filter unit housing 10 is provided with a snap-fit ​​131, and the other side is provided with a slot, with the snap-fit ​​131 engaging with the slot. This facilitates quick assembly and disassembly, improving maintenance convenience. The snap-fit ​​131 is designed with a flexible structure to ensure a tight connection and prevent accidental detachment. The slot has a moderate depth to ensure that the snap-fit ​​131 is securely embedded, improving the overall structural reliability.

[0069] In some embodiments, combined with Figure 3 As shown, the noise reduction assembly 24 includes:

[0070] Sound-absorbing materials 241;

[0071] The inner shell 245 is partially connected to form a variable diameter pipe 243. The inner shell 245 and the inner wall of the silencing unit shell 20 together form a Helmholtz resonant cavity 244. The inner shell 245 is connected to form a through hole, which is suitable for connecting the Helmholtz resonant cavity 244 and the variable diameter pipe 243.

[0072] The sound-absorbing material 241 forms a resistive noise-absorbing section, which effectively absorbs high-frequency noise.

[0073] The variable diameter pipe 243 and the Helmholtz resonant cavity 244 together form an anti-noise section. Through the resonance effect of the Helmholtz resonant cavity 244, the mid-to-low frequency noise is further reduced, and the noise across the entire frequency band is effectively controlled.

[0074] The sound-absorbing material 241 can specifically be sound-absorbing cotton, such as sound-absorbing cotton with a composite layer of glass fiber and polyester fiber. The sound-absorbing cotton can effectively absorb high-frequency noise and reduce noise propagation. The noise reduction is ≥20dB(A).

[0075] In this embodiment, a sound-absorbing cavity 23 is formed inside the housing 20 of the sound-absorbing unit. The sound-absorbing material 241 is filled in the sound-absorbing cavity 23 and closely adheres to the inner wall to ensure that the sound waves are absorbed by multiple reflections, thereby enhancing the sound-absorbing effect.

[0076] Additionally, the silencing unit housing 20 is provided with a drainage hole to facilitate the drainage of condensate and prevent the sound-absorbing material 241 from becoming damp and failing.

[0077] The inner shell 245 can be annular. By placing the inner shell 245 inside the silencing unit housing 20, a variable-diameter pipe 243 is formed through the center of the inner shell 245. The inner shell 245 and the inner wall of the silencing unit housing 20 together form a Helmholtz resonant cavity 244. A through-hole is formed through the inner shell 245, suitable for connecting the Helmholtz resonant cavity 244 to the variable-diameter pipe 243. This allows sound waves to be reflected multiple times between the Helmholtz resonant cavity 244 and the variable-diameter pipe 243, enhancing noise attenuation and improving overall silencing performance.

[0078] In some embodiments, the noise reduction component 24 further includes a perforated screen 242, which has a plurality of through holes and is disposed between the sound-absorbing material 241 and the inner shell 245.

[0079] The perforated screen 242 can be a plate-like structure. By placing the perforated screen 242 between the sound-absorbing material 241 and the inner shell 245, the sound waves are scattered in the through holes of the perforated screen 242, which further improves the sound absorption effect, ensures multi-level noise attenuation, and enhances the overall noise reduction performance.

[0081] The compressor body, and the integrated filter silencer as described above;

The air inlet of the compressor body is adapted to be connected to the filter outlet connector 11 via a pipe, and the air outlet of the compressor body is adapted to be connected to the silencer inlet connector 21 via another pipe.

[0083] In this embodiment, the air inlet and outlet of the compressor body are located on the same side, thereby allowing the integrated filter silencer to be located on one side of the compressor body, simplifying the pipeline layout, reducing installation space, and improving the overall compactness and ease of maintenance of the equipment.

[0084] According to an embodiment of the present invention, in another aspect, a vehicle is also provided, comprising:
