[0029] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0030] Reference below Figure 1-Figure 5 The muffler assembly 100 according to an embodiment of the present invention is described, and the muffler assembly 100 is applied to a vehicle, for example, a city SUV and an off-road SUV.

[0031] like Figure 1-Figure 3As shown, according to the muffler assembly 100 of the present invention, the muffler assembly 100 includes: a muffler shell 10 and a protective component 20. The protective component 20 is arranged at the bottom of the muffler shell 10 and extends downward to contact the obstacle before the muffler shell 10.

[0032] It can be understood that the muffler shell 10 and the protective component 20 constitute the main structure of the muffler assembly 100. The muffler shell 10 can protect the components inside the muffler assembly 100, so that the muffler assembly 100 can reduce the exhaust noise discharged by the engine. The protective component 20 is arranged below the muffler shell 10, so that the protective component 20 does not affect the arrangement of other components on the muffler shell 10, which is beneficial to the arrangement of the entire vehicle, and the protective component 20 extends downward, so that the protective component 20 protrudes from the muffler shell 10. When the vehicle is off-road or driving on other complex road conditions, the protective component 20 first contacts the obstacle, and the muffler shell 10 does not contact the obstacle, thereby preventing the obstacle from damaging the muffler shell 10, thereby improving the driving experience of the driver and passengers, and extending the service life of the muffler shell 10.

[0033] Therefore, by arranging the protective component 20 at the bottom of the muffler shell 10, and the protective component 20 extending downward, this arrangement can make the protective component 20 contact the obstacle first relative to the muffler shell 10 when the vehicle is off-road, thereby preventing the vehicle from damaging the muffler shell 10 under complex road conditions, thereby improving the driving experience of the driver and passengers, and extending the service life of the muffler shell 10.

[0034] Among them, such as Figure 4 and Figure 5 As shown, the protection assembly 20 includes: a first protection bracket 21 and a second protection bracket 22. The first protection bracket 21 is connected to the bottom of the muffler housing 10 and partially protrudes downward. The second protection bracket 22 is detachably installed below the first protection bracket 21.

[0035] That is, the first protective bracket 21 is disposed at the bottom of the muffler housing 10, and the second protective bracket 22 is located below the first protective bracket 21. The second protective bracket 22 is detachable from the first protective bracket 21. When the vehicle needs to go off-road or travel on complex roads, the second protective bracket 22 is installed below the first protective bracket 21. The first and second protective brackets 21 and 22 protrude from the bottom of the muffler housing 10. This allows the first and second protective brackets 21 and 22 to contact obstacles first, while the muffler housing 10 does not. This prevents obstacles from damaging the muffler housing 10, thereby improving the driving experience for the driver and passengers and extending the service life of the muffler housing 10. When the vehicle does not need to go off-road or travel on complex roads, the second protective bracket 22 is detached from the first protective bracket 21. In this case, only the first protective bracket 21 is disposed at the bottom of the muffler housing 10, and the vehicle can travel on urban roads. This not only facilitates the platform design of the muffler assembly 100, but also reduces vehicle development costs, thereby facilitating the installation and use of the protective assembly 20 in the vehicle.

[0036] In addition, if Figure 4 and Figure 5 As shown, the first protective bracket 21 includes: a first mounting plate 211 and a connecting plate 212. The first mounting plate 211 is located below the muffler shell 10. The second protective bracket 22 is detachably mounted on the first mounting plate 211. The connecting plate 212 is connected to both sides of the first mounting plate 211 and is bent upward. The connecting plate 212 is connected to the bottom of the muffler shell 10.

[0037] It can be understood that the first mounting plate 211 and the connecting plate 212 constitute the main structure of the first protective bracket 21. The first mounting plate 211 is connected to the bottom of the muffler shell 10, and the second protective bracket 22 is detachably connected to the first mounting plate 211. In this way, the first mounting plate 211 can provide a mounting position for the second protective bracket 22, thereby facilitating the disassembly and installation of the second protective bracket 22 and the first protective bracket 21, and also facilitating the platform design of the muffler assembly 100. The connecting plate 212 is located on the left and right sides of the first mounting plate 211, and the connecting plate 212 is bent upward relative to the first mounting plate 211. The connecting plate 212 is welded to the muffler shell 10, so that a certain space can be formed between the first mounting plate 211, the connecting plate 212 and the muffler shell 10, thereby improving the strength of the first protective bracket 21 and the strength between the first protective bracket 21 and the muffler shell 10.

[0038] In addition, if Figure 4 and Figure 5As shown, the second protective bracket 22 includes: a second mounting plate 221 and a protective plate 222. The second mounting plate 221 is arranged below the first mounting plate 211. The second mounting plate 221 is detachably mounted on the first mounting plate 211. The protective plate 222 is connected to the bottom of the second mounting plate 221.

[0039] That is to say, the second mounting plate 221 and the protective plate 222 constitute the main structure of the second protective bracket 22, the second mounting plate 221 is located below the first mounting plate 211, and the second mounting plate 221 is detachable relative to the first mounting plate 211, and the space below the first mounting plate 211 is large, so that the second mounting plate 221 is conveniently connected to the bottom of the first mounting plate 211, thereby facilitating the installation and removal between the first protective bracket 21 and the second protective bracket 22. When the vehicle does not need to go off-road or travel on complex road conditions, the second mounting plate 221 is relatively close to the first mounting plate 211. The mounting plate 211 is removed, and at this time only the first mounting plate 211 and the connecting plate 212 are arranged at the bottom of the muffler shell 10. The vehicle can be driven on urban roads without increasing the weight of the vehicle. The protective plate 222 is connected to the lower side of the second mounting plate 221. When the vehicle is off-road or driving on other complex road conditions, the protective plate 222 first contacts the obstacle, and the muffler shell 10 does not contact the obstacle, thereby preventing the obstacle from damaging the muffler shell 10, thereby improving the driving experience of the driver and passengers, and extending the service life of the muffler shell 10.

[0040] In particular, if Figure 4 and Figure 5 As shown, the bottom surface of the protective plate 222 is constructed as a slope inclined downward from the front to the rear, and flanges 225 are provided on both sides of the second mounting plate 221, and overlapping edges 223 are provided on both sides of the protective plate 222. The flanges 225 and the overlapping edges 223 are connected one by one.

[0041] It can be understood that the flanges 225 on the left and right sides of the second mounting plate 221 are set to gradually reduce the width from top to bottom, and the flanges 225 of the second mounting plate 221 form a triangular plate extending downward, which can not only ensure the stability of the second mounting plate 221, but also save the cost of the protective assembly 20. One side surface of the protective plate 222 forms an inclined surface inclined downward from the front to the rear, so that the protective plate 222 can cover the front end of the flange 225, which can not only form a wedge-shaped box-like structure between the protective plate 222 and the second mounting plate 221, but also make the inclined surface of the protective plate 222 contact the obstacle first, or the obstacle slides along the inclined surface, and guides the obstacle not to approach the muffler housing 10, and can also reduce the risk of the protective plate 222 colliding head-on with the obstacle. The contact area can improve the overall structural strength of the second protective component 20, ensure that the muffler shell 10 does not contact the obstacle, and reduce the vibration caused by the collision between the protective component 20 and the obstacle. In addition, overlapping edges 223 are provided on the left and right sides of the protective plate 222, and the overlapping edges 223 correspond to the flanges 225 one by one. It is not only convenient for the flanges 225 and the overlapping edges 223 to respectively limit the installation between the second mounting plate 221 and the protective plate 222, but also convenient for the welding connection between the overlapping edges 223 and the flanges 225. In this way, the structural strength of the second protective component 20 can be ensured, so that after the second protective bracket 22 is released from the obstacle, the muffler shell 10 is ensured to no longer contact the obstacle, thereby preventing the muffler shell 10 from being damaged.

[0042] In addition, if Figure 4 and Figure 5 As shown, the first mounting plate 211 is provided with a first through-hole, the second mounting plate 221 is provided with a second through-hole, and the protective plate 222 is provided with a tool through-hole 226. The first through-hole, the second through-hole and the tool through-hole 226 are arranged relative to each other; the protective component 20 also includes: a fastener, which passes through the first through-hole and the second through-hole, so that the first mounting plate 211 and the second mounting plate 221 can be connected.

[0043] That is to say, a first through-hole is set in the middle of the first mounting plate 211, a second through-hole is set in the middle of the second mounting plate 221, and a tool through-hole 226 is set in the middle of the protective plate 222. The first through-hole, the second through-hole and the tool through-hole 226 are arranged relative to each other, which can not only make the first through-hole, the second through-hole and the tool through-hole 226 limit the first mounting plate 211 and the second mounting plate 221, but also make the second mounting plate 221 and the first mounting plate 211 maintain left-right balance after installation. The fastener is a screw 24, and the nut 23 is welded on the first mounting plate 211, and the nut 23 corresponds to the first through-hole, so that the screw 24 can pass through the tool through-hole 226, the second through-hole and the first through-hole in sequence and then be screwed to the nut 23. The screw 24 is located in the space formed between the first mounting plate 211, the connecting plate 212 and the muffler shell 10. When the vehicle does not need to go off-road or is driving on complex road conditions, the screw 24 and the nut 23 Without screwing, the second protective bracket 22 is removed relative to the first protective bracket 21. At this time, only the first protective bracket 21 is set at the bottom of the muffler shell 10, and the vehicle can be driven on urban roads. This is not only beneficial to the platform design of the muffler assembly 100, but also can reduce the development cost of the vehicle, thereby facilitating the installation and application of the protective component 20 in the vehicle. When the vehicle needs to go off-road or drive on complex road conditions, the screw 24 is screwed to the nut 23, and the second protective bracket 22 is installed on the first protective bracket 21. The first protective bracket 21 and the second protective bracket 22 protrude relative to the bottom of the muffler shell 10, so that the first protective bracket 21 and the second protective bracket 22 can contact the obstacle first, and the muffler shell 10 does not contact the obstacle, thereby avoiding the obstacle from damaging the muffler shell 10, thereby improving the driving experience of the driver and passengers, and extending the service life of the muffler shell 10.

[0044] In particular, Figure 4 and Figure 5 As shown, the second protective bracket 22 further includes: a limiting portion 224, which is arranged on at least one side of the outer periphery of the second mounting plate 221, and the limiting portion 224 cooperates with the first mounting plate 211 to limit the circumferential position of the second mounting plate 221.

[0045] It can be understood that the limiting portion 224 is located on at least one side of the front-to-back direction of the second mounting plate 221. For example, the limiting portion 224 is arranged on the front edge and the rear edge of the second mounting plate 221, and the limiting portion 224 extends upward, so that the limiting portion 224 can limit the second mounting plate 221 and the first mounting plate 211, and then the first through-hole and the second through-hole are arranged relative to each other, so that the second mounting plate 221 and the first mounting plate 211 can maintain left-right balance after installation, thereby facilitating the screw 24 to pass through the tool through-hole 226, the second through-hole and the first through-hole in sequence and then be screwed to the nut 23.

[0046] In addition, Figure 1-Figure 3 As shown, the muffler shell 10 includes: an upper shell 11 and a lower shell 12, the lower shell 12 is connected to the bottom of the upper shell 11, and the protective component 20 is arranged at the lowest point of the bottom of the lower shell 12; the muffler shell 10 has an air inlet end 13 and an exhaust end 14, and the protective component 20 is arranged at the bottom of the air inlet end 13.

[0047] That is to say, the upper shell 11 and the lower shell 12 are relatively connected in the up and down directions to form the main body of the muffler shell 10, so that an installation space can be formed between the upper shell 11 and the lower shell 12, thereby facilitating the arrangement of other components inside the muffler shell 10. The lower surface of the lower shell 12 is arc-shaped, and the protective component 20 is arranged at the lowest point of the lower shell 12. This can ensure that when the vehicle is off-road or driving on special road conditions, obstacles first contact the protective component 20, thereby preventing obstacles from contacting the lower shell 12, and further preventing the muffler shell 10 from being damaged, as well as damage to other internal components.

[0048] The front end of the muffler shell 10 is the air intake end 13, and the rear end is the exhaust end 14. The protective component 20 is located at the bottom of the air intake end 13. When the vehicle is driving, the air intake end 13 approaches the obstacle first relative to the exhaust end 14, and the protective component 20 contacts the obstacle first relative to the muffler shell 10, thereby preventing the obstacle from contacting the lower shell 12, and further preventing the muffler shell 10 from being damaged, as well as damage to other internal components.

[0049] Among them, such as Figure 1-Figure 3 As shown, a connecting flange 30 is provided on the intake end 13, and an exhaust tail pipe 40 is provided on the exhaust end 14. The connecting flange 30 is connected to the exhaust manifold of the engine, so that the exhaust gas of the engine can enter the muffler housing 10 through the exhaust manifold and the intake end 13, and be discharged from the exhaust tail pipe 40 after noise reduction and harm removal by the muffler housing 10. A plurality of hook assemblies 50 are provided on the muffler housing 10, and the hook assemblies 50 are connected to the chassis, so that the muffler housing 10 can be fixed on the chassis, thereby ensuring the stability of the muffler housing 10.

[0050] A vehicle according to the present invention includes the muffler assembly 100 of the above embodiment. A protective assembly 20 is provided at the bottom of the muffler housing 10, and the protective assembly 20 extends downward. This arrangement allows the protective assembly 20 to contact obstacles before the muffler housing 10 during off-road driving, thereby preventing damage to the muffler housing 10 caused by the vehicle under complex road conditions. This improves the driving experience for the driver and passengers and extends the service life of the muffler housing 10.
