Description

Technical Field

[0001] This utility model relates to the field of air suspension technology, specifically to an exhaust muffler for vehicle air suspension. Background Technology

[0002] Vehicles utilize air suspension systems to adjust their ride height, thereby improving comfort and stability. Air suspension systems use an air supply unit to provide dry compressed air for height adjustment. The air supply unit not only inflates the air suspension system to raise the vehicle's level but also exhausts air when lowering the ride height.

[0003] However, the air exhausted from an air suspension system is typically high-pressure gas, which generates significant noise during exhaust and requires a muffler to reduce it. Furthermore, existing mufflers are relatively complex in structure and exhibit high flow resistance when high-pressure gas is input. This not only increases the air supply unit's charging time but also puts considerable pressure on the exhaust pipe, reducing the stability and reliability of the air suspension system.

[0004] Therefore, it is necessary to provide new exhaust mufflers for vehicle air suspension. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0030] Throughout this specification, reference to "an embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of this application. Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0031] like Figure 1 As shown, this embodiment provides an exhaust muffler 100 for a vehicle air suspension, including a muffler housing 1, a core 2 disposed inside the muffler housing 1, and an end cap 3 covering the muffler housing 1. The muffler housing 1 accommodates the core 3 and provides structural support; the core 2 absorbs exhaust noise to achieve noise reduction; and the end cap 3 forms a closed structure and fixes the core 2.

[0032] In some embodiments, the muffler housing 1 includes a mounting shell 11 and an air inlet pipe 12 disposed at one end of the mounting shell 11. The mounting shell 11 is generally cylindrical, forming a receiving cavity inside for housing the core 2. One end of the air inlet pipe 12 communicates with the interior of the mounting shell 11, allowing high-pressure gas to enter the mounting shell 11. Multiple support protrusions 13 are circumferentially arranged on the bottom inner wall of the mounting shell 11, wherein adjacent support protrusions 13 have different lengths, and the support protrusions 13 support the lower end face of the core 2. Furthermore, when high-pressure gas enters the interior of the mounting shell 11 through the air inlet pipe 12, the high-pressure gas is dispersed outwards between the two support protrusions 13 on the bottom inner wall of the mounting shell 11, thereby ensuring that the input high-pressure gas enters the core 2 uniformly.

[0033] In some embodiments, a plurality of first grilles 14 are also formed on the side wall of the mounting housing 11. The plurality of first grilles 14 are circumferentially formed on the side wall of the mounting housing 11 and are evenly distributed in a strip shape. After the high-pressure gas passes through the core 2 for noise reduction, it can be discharged through the first grilles 14 on the side wall of the mounting housing 11, which increases the effective cross-sectional area through which the high-pressure gas flows, reduces the exhaust resistance, shortens the inflation time of the air supply unit, improves the efficiency of the air suspension system, and avoids or reduces the risk of pipe rupture caused by excessive flow resistance. Furthermore, it can reduce the strength requirements of the pipe material and achieve cost savings.

[0034] In some other embodiments not shown in the figures, a first grille 14 is provided on the side wall of the mounting housing 11, and the first grille 14 is a mesh-like through hole.

[0035] In some embodiments, the top of the mounting housing 11 is further provided with a mating portion 15 and locking protrusions 16 symmetrically arranged on the mounting housing 11. The mating portion 15 is generally stepped and is used for mating with the end cap 3. The locking protrusions 16 are integrally formed with the mounting housing 11, and two locking protrusions 16 are provided, symmetrically arranged on the top edge of the mounting housing 11. The locking protrusions 16 are used for mating and fixing with the end cap 3.

[0036] In some embodiments, a quick-connect locking member 17 is also provided on the side wall of the mounting shell 11. The quick-connect locking member 17 and the mounting shell 11 are integrally formed. The quick-connect locking member 17 is a standard snap-fit ​​interface structure. The quick-connect locking member 17 adopts a mechanical interlocking design. The quick-connect locking member 17 includes a hook 171 and a slot 172, which forms a quick-connect engagement with the corresponding interface on the air suspension system, thereby fixing the entire muffler 100. This enables the muffler 100 to be quickly and securely connected to the corresponding interface on the air suspension system, greatly simplifying the vehicle assembly process, reducing the complexity of manual operation, and improving production line efficiency.

[0037] In some embodiments, the core 2 is generally cylindrical, and its dimensions match the dimensions of the internal cavity of the mounting housing 11. The core 2 is made of a porous rigid material; for example, it may be a porous metal or a porous engineering plastic. The core 2 has a uniformly distributed microporous structure, and the pore size meets the noise reduction requirements. The micropores inside the core 2 are interconnected, forming an airflow channel network, which not only ensures smooth exhaust and reduces flow resistance, but also achieves noise reduction through the sound energy absorption characteristics of the porous material.

[0038] In some embodiments, the top of the end cap 3 is a circular cover, and the size of the end cap 3 matches the muffler housing 1. The side of the end cap 3 matches the mating part 15 on the top of the mounting housing 11, so that the end cap 3 covers the mating part 15. A second grille 31 is provided on the top of the end cap 3. The second grille 31 is evenly distributed on the top of the end cap 3 and has a mesh-like through hole, so that the high-pressure gas after noise reduction by the core 2 can not only be discharged through the first grille 14 on the side wall of the mounting housing 11, but also be discharged from the second grille 31 on the end cap 3. This further increases the effective cross-sectional area through which the high-pressure airflow passes, reduces exhaust resistance, shortens the inflation time of the air supply unit, improves the efficiency of the air suspension system, and avoids and reduces the risk of pipe rupture caused by excessive flow resistance. It can also reduce the strength requirements of the pipe material and achieve cost savings.

[0039] In some embodiments, two latches 32 are provided on both sides of the end cap 3, symmetrically arranged on both sides of the end cap 3. The latches 32 match two locking bosses 16 symmetrically arranged on the top edge of the mounting shell 11, for quick snap-fit ​​fixing of the muffler shell 1 and the end cap 3, thereby sealing the muffler cavity. During assembly, the mechanical engagement between the latches 32 and the locking bosses 16 requires no additional tools, simplifying the installation process and improving assembly efficiency.

[0040] The exhaust muffler 100 for vehicle air suspension of this utility model first places the core 2 into the internal cavity of the mounting shell 11 of the muffler housing 1. The lower end face of the core 2 is supported by the support boss 13 circumferentially arranged on the bottom of the inner wall of the mounting shell 11, thereby achieving the positioning and support of the core. Then, the side of the end cap 3 is aligned with the mating part 15 on the top of the mounting shell 11 and installed, so that the end cap 3 covers the muffler housing 1. Then, the fasteners 32 on both sides of the end cap 3 mechanically engage with the locking bosses 16 symmetrically arranged on the top of the mounting shell 11, thereby achieving quick snap-fit ​​fixation between the muffler housing 1 and the end cap 3, forming a closed cavity. In addition, the quick-connect locking member 17 is used for quick engagement between the exhaust muffler 100 and the corresponding interface of the air suspension system, thereby achieving overall fixed connection of the muffler.

[0041] The exhaust muffler 100 for vehicle air suspension of this utility model includes a muffler housing 1, a core 2 disposed inside the muffler housing 1, and an end cap 3 covering the muffler housing 1. The muffler housing 1 includes a mounting shell 11 and an air intake pipe 12 disposed at one end of the mounting shell 11. The mounting shell 11 forms a receiving cavity inside, and its inner wall bottom is provided with a plurality of support protrusions 13 of different lengths in the circumferential direction, and the side wall is provided with a plurality of first grilles 14. The core 2 is disposed inside the mounting shell 11, is made of porous rigid material and has through micropores inside. The end cap 3 covers the top of the mounting shell 11, and the top of the end cap 3 is provided with a second grille 31, and fasteners 32 are provided on both sides. The top of the mounting shell 11 is provided with a locking protrusion 16 that matches the fasteners 32 to achieve quick snap-fit ​​fixation. The exhaust muffler 100 for vehicle air suspension of this utility model has multiple adjacent support protrusions 13 of different lengths set at the bottom of the inner wall of the mounting shell 11. After the high-pressure gas enters the mounting shell 11 through the air intake pipe 12, it is dispersed to the surrounding area through the support protrusions 13, so that the high-pressure gas enters the core evenly, thereby improving the exhaust muffler effect. Multiple circumferentially evenly distributed strip-shaped first grilles 14 on the side wall of the mounting shell 11 and mesh through-hole second grilles 31 on the top of the end cover increase the effective cross-sectional area of ​​the high-pressure airflow discharge, effectively reduce exhaust resistance, shorten the inflation time of the air supply unit, and significantly improve the overall efficiency of the air suspension system. At the same time, it reduces the risk of pipe rupture due to excessive flow resistance, reduces the requirements for pipe strength, achieves the purpose of cost saving, and provides a more reliable guarantee for the operation of the vehicle air suspension system. The locking protrusion 16 set on the top of the mounting shell 11 cooperates with the buckle 32 of the end cover 3, the assembly process is simple and quick, greatly reduces the complexity of manual operation, and significantly improves the efficiency of the production line.

[0042] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
