Detailed Implementation

[0028] To better understand the above-mentioned objectives, features, and advantages of this application, embodiments of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0029] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "front", "rear", "bottom", "inner", "outer" and other terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after the connection. Furthermore, the directional terms mentioned in the embodiments of this application, such as "inner" and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0031] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0032] The air supply unit of the air suspension assembly has an intake pipe and an exhaust pipe. In order to reduce the exhaust noise of the air supply unit, a separate exhaust muffler needs to be installed at the end of the exhaust pipe. However, since the exhaust muffler and the intake pipe are prone to spatial interference when arranged, the intake pipe and the exhaust pipe need to be arranged separately, which makes the air suspension assembly occupy a large space and has a high cost.

[0033] In view of this, embodiments of this application provide a muffler, an air suspension assembly, and a vehicle that can reduce the size of the air suspension assembly.

[0034] The silencer of the present application embodiment will be described below.

[0035] Please refer to Figures 1 to 3. Figure 1 is a cross-sectional view of a muffler provided in some embodiments of this application. Figure 2 is a partial schematic diagram of the connection between the muffler and the air supply unit provided in some embodiments of this application. Figure 3 is a perspective view of a muffler provided in some embodiments of this application. The muffler 100 is applied to the air supply unit of an air suspension assembly. The muffler 100 includes a guide vane 1, a housing 2, an intake end cap 3, and a muffler component 4.

[0036] The shell 2 has a receiving space 21, wherein the receiving space 21 is the space enclosed by the inner wall of the shell 2. The shell 2 can be in the shape of a cube, cylinder, etc., and the shape of the receiving space 21 can be similar to the shape of the shell 2. This application does not limit this.

[0037] The guide plate 1 abuts against the inner wall of the housing 2 to divide the accommodating space 21 into a silencing chamber 211 and a pressure-reducing chamber 212. The guide plate 1 has a guide hole (not shown in the figure), through which the silencing chamber 211 and the pressure-reducing chamber 212 communicate. Specifically, the guide hole penetrates the guide plate 1, allowing gas located in the pressure-reducing chamber 212 to flow into the silencing chamber 211.

[0038] The silencer 4 is disposed inside the silencer cavity 211. Specifically, the silencer cavity 211 is filled with the silencer 4, which can reduce the noise when gas passes through.

[0039] The silencing cavity 211 has an exhaust port 2111. For example, there can be multiple exhaust ports 2111, and the multiple exhaust ports 2111 can be spaced apart in the circumferential direction at the edge of the end of the housing 2.

[0040] The pressure-reducing chamber 212 has an exhaust port 2122, which is used to connect to the exhaust pipe 300. Specifically, the compressed air discharged by the air supply unit through the exhaust pipe 300 can first enter the pressure-reducing chamber 212 through the exhaust port 2122. The flow rate and pressure of the compressed air entering the pressure-reducing chamber 212 are reduced, and then it flows into the silencer chamber 211 through the guide hole. After the silencer 4 in the silencer chamber 211 is silenced, it is finally discharged from the exhaust port 2111.

[0041] Therefore, the compressed air discharged from the air supply unit can be dispersed through the pressure reduction chamber 212, which helps to improve the utilization rate of the silencer 4 and thus improve the silencing effect of the silencer 100.

[0042] For example, the muffler 4 can be a hydrophobic muffler material, so that the muffler 4 has both sound absorption and hydrophobic properties, thereby reducing the flow resistance of the muffler 100 and facilitating the discharge of liquid water by compressed air. Combined with the low-level drainage design, under natural conditions, liquid water can flow out from the exhaust port 2111 of the muffler 100 by gravity.

[0043] For example, the silencing component 4 can be polyimide foam, rigid polyvinyl chloride silencing pipe, etc., and this application does not limit it.

[0044] An air intake end cap 3 extends from one side of the housing 2 away from the housing 2 to form an air intake chamber 31. The end of the air intake chamber 31 away from the housing 2 has an air intake port 32 and an air intake end 33. The air intake end 33 can be used to connect to the air supply pipe 200. Specifically, since the air intake port 32 is connected to the outside, and the air intake end 33 is connected to the air supply pipe 200, the air intake port 32 can draw outside air into the air intake chamber 31. The air in the air intake chamber 31 then enters the air supply pipe 200 through the air intake end 33, thereby achieving air supply to the air supply unit. It can be understood that outside air can be compressed in the compressor before entering the air intake chamber 31.

[0045] For example, the intake end cap 3 and the housing 2 can be integrally molded. This can improve the connection strength between the intake end cap 3 and the housing 2, and also help reduce the assembly difficulty of the muffler 100.

[0046] According to the muffler 100 of the present application embodiment, an exhaust port 2122 for connecting to an exhaust pipe 300 is provided on the housing 2, and an intake end cover 3 is provided on one side of the housing 2, so that the intake port 33 of the intake end cover 3 is connected to the air supply pipe 200. This allows both the intake pipe and the exhaust pipe of the air supply unit to be connected to the muffler 100, which helps to reduce the volume of the air suspension assembly and also helps to reduce the cost of the air suspension assembly. Meanwhile, the guide plate 1 divides the housing 2's accommodating space 21 into a silencing chamber 211 and a pressure-reducing chamber 212. A silencing component 4 is installed in the silencing chamber 211. The compressed air discharged from the exhaust port 2122 will first have its flow rate and pressure reduced in the pressure-reducing chamber 212, and then flow into the silencing chamber 211 through the guide holes on the guide plate 1. After being silenced by the silencing component 4, it will finally be discharged from the exhaust port 2111. This will help improve the utilization rate of the silencing component 4 and also help improve the noise reduction effect of the muffler 100, thereby improving the user experience.

[0047] Please continue referring to Figures 1 to 3. In some embodiments, an air intake connector 34 may be provided at the air intake port 33. The air intake connector 34 can be used to connect the air supply pipe 200. This facilitates the connection of the air supply pipe 200 by the operator, thereby improving the assembly efficiency of the air suspension assembly.

[0048] A portion of the intake connector 34 is located within the intake chamber 31, and in the extending direction of the intake chamber 31, the length of the intake connector 34 extending into the intake chamber 31 is greater than the length of the intake port 32. Specifically, in the extending direction of the intake chamber 31 (the vertical direction in Figure 1), the portion of the intake connector 34 extending into the intake chamber 31 can extend beyond the intake port 32. The portion of the intake connector 34 within the intake chamber 31 communicates with the intake port 32, while the portion outside the intake chamber 31 is used to connect to the air supply pipe 200. This reduces the risk of larger particles and liquid water being inhaled by the air supply unit, thereby improving the reliability of the air suspension assembly.

[0049] For example, there can be multiple air intake ports 32, which can be spaced apart in the circumferential direction of the air intake connector 34. This helps to improve the air intake efficiency of the air supply unit.

[0050] Please refer to Figures 1 to 3. In some embodiments, the muffler 100 may further include a first limiting member 341. The first limiting member 341 extends from the outer surface of the suction connector 34 in a direction away from the suction connector 34 and has a gap with the suction port 32. Specifically, the first limiting member 341 is disposed on the outer surface of the suction connector 34, and in the radial direction of the suction connector 34, the first limiting member 341 extends in a direction away from the suction connector 34, that is, the first limiting member 341 extends radially outward from the outer surface of the suction connector 34. Thus, the installation position of the air supply pipe 200 can be restricted by the first limiting member 341, ensuring that the air supply pipe 200 can be installed in place during the installation process, thereby improving the assembly efficiency of the air supply pipe 200. At the same time, it can also prevent the air supply pipe 200 from affecting the intake of the suction port 32.

[0051] Please refer to Figures 1 to 3. In some embodiments, the outer surface of the suction connector 34 may be provided with multiple limiting protrusions 342. These limiting protrusions 342 are spaced apart along the length of the suction connector 34. The cross-sectional area of ​​the limiting protrusions 342 gradually increases from one end of the suction connector 34 away from the suction end cap 3 to the other end of the suction connector 34. Therefore, the limiting protrusions 342 can guide the installation of the air supply pipe 200, and the air supply pipe 200 can be secured within the gap between two adjacent limiting protrusions 342. Furthermore, the simple structure of the limiting protrusions 342 helps improve the assembly efficiency of the air supply pipe 200 and reduces the manufacturing cost of the muffler 100.

[0052] Please refer to Figures 1 to 3. In some embodiments, the muffler 100 may further include an exhaust connector 213. The exhaust connector 213 is disposed at the exhaust port 2122 and is used to connect the exhaust pipe 300. The outer surface of the exhaust connector 213 may be provided with a second limiting member 214. The second limiting member 214 extends from the outer surface of the exhaust connector 213 in a direction away from the exhaust connector 213 and has a gap with the housing 2. Thus, the installation position of the exhaust pipe 300 can be restricted by the second limiting member 214, ensuring that the exhaust pipe 300 can be installed in place during the installation process, thereby improving the assembly efficiency of the exhaust pipe 300.

[0053] It should be noted that the structure of the exhaust connector 213 can be similar to that of the intake connector 34, that is, the exhaust connector 213 can also be provided with a limiting protrusion 342, which will not be elaborated here.

[0054] Please refer to Figures 1 to 3. In some embodiments, the guide hole may include a first through hole and a second through hole. The second through hole is located on the side of the first through hole near the exhaust port 2122, and the diameter of the second through hole is larger than that of the first through hole. Specifically, the flow velocity of compressed air can be reduced by passing through the first through hole. Thus, during the process of compressed air flowing from the pressure-reducing chamber 212 to the muffler chamber 211 through the guide hole, the flow velocity of compressed air flowing into the muffler chamber 211 can be controlled by the first and second through holes with different diameters, so that the flow velocities of compressed air flowing into the muffler chamber 211 can be similar, thereby improving the utilization rate of the muffler 4 and thus improving the noise reduction effect of the muffler 100.

[0055] Please refer to Figures 1 to 3. In some embodiments, the housing 2 may include a first outer shell 22 and a second outer shell 23. A silencing cavity 211 may be located in the first outer shell 22, and the side of the silencing cavity 211 facing the guide plate 1 has a first opening 221. A pressure-reducing cavity 212 may be located in the second outer shell 23, and the side of the pressure-reducing cavity 212 facing the guide plate 1 has a second opening 231. The first outer shell 22 and the second outer shell 23 are connected by the guide plate 1. Specifically, one side of the guide plate 1 is connected to the first outer shell 22 and blocks the first opening 221, and the other side of the guide plate 1 is connected to the second outer shell 23 and blocks the second opening 231. This arrangement facilitates the filling of the silencing component 4 into the silencing cavity 211 through the first opening 221. Simultaneously, the structure is simple and easy to assemble, thereby helping to reduce the manufacturing cost of the muffler 100.

[0056] Please refer to Figures 1 to 3. In some embodiments, the housing 2 may further include a support member 24. The support member 24 is fitted at the connection between the first outer shell 22 and the second outer shell 23, and the guide plate 1 is connected to the support member 24. Specifically, the support member 24 can be connected to the first outer shell 22 first, and then the guide plate 1 can be placed at the first opening 221, so that the guide plate 1 abuts against the first outer shell 22 and the support member 24. Then, the second outer shell 23 abuts against the guide plate 1 and connects to the support member 24. The guide plate 1 is then secured by the first outer shell 22 and the second outer shell 23, thus completing the assembly of the guide plate 1. Therefore, by providing the support member 24, support can be provided for the installation of the guide plate 1, allowing for better assembly of the guide plate 1 and reducing the difficulty of assembly, thereby improving the assembly efficiency of the muffler 100.

[0057] For example, the first outer shell 22 can be a plastic with a certain light transmittance, and the second outer shell 23 can be a plastic with poor light transmittance. Adding a color masterbatch, such as black particles, to the plastic can reduce light transmittance. The second outer shell 23 and the support member 24 can be laser-welded together. The support member 24 can also be a plastic with a certain light transmittance. Specifically, the laser generates heat at the inner overlapping area (the non-transparent layer, such as the plastic with poor light transmittance) after penetrating the transparent plastic, thereby melting the two layers of plastic together to achieve welding.

[0058] For example, the first housing 22 and the intake end cap 3 can be integrally molded. This can improve the connection strength between the first housing 22 and the intake end cap 3, and also help reduce the assembly difficulty of the muffler 100.

[0059] For example, the first housing 22 and the support member 24 can be integrally molded. This can improve the connection strength between the first housing 22 and the support member 24, and also facilitate the installation of the second housing 23, thereby improving the assembly efficiency of the muffler 100.

[0060] Please continue referring to Figures 1 through 3. In some embodiments, the exhaust port 2122 and the intake port 33 may be located on the same side of the housing 2. This allows for better arrangement of the air supply pipe 200 and the exhaust pipe 300, saving space and thus helping to reduce the weight and manufacturing cost of the air suspension assembly.

[0061] The air suspension assembly of the present application embodiment will be described below.

[0062] The air suspension assembly of this application embodiment includes an air supply unit and a muffler 100 as described in any of the above embodiments. This is advantageous in reducing the size and cost of the air suspension assembly.

[0063] The vehicle described in the embodiments of this application will now be described.

[0064] The vehicle in this application embodiment includes the aforementioned air suspension assembly. The vehicle can be a new energy vehicle, an electric vehicle, a gasoline-powered vehicle, etc. This helps reduce the noise of the air suspension assembly during operation, thereby improving the vehicle's quietness.

[0065] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0066] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
