[0051] In order to make the technical scheme of the utility model and its advantages clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0052] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0053] In addition, in the description of the utility model, it needs to be explained that if the terms indicating the orientation or position relationship such as ''up'', ''down'', ''inner'', ''outer'' etc. appear, it is based on the orientation or position relationship shown in the drawing, and it is only for the convenience of describing the utility model and simplifying the description, and therefore it cannot be understood as the limitation of the utility model to the indicated device or element must have a specific orientation, a specific orientation and operation, and therefore it cannot be understood as the limitation of the utility model.

[0054] In addition, in the description of the utility model, unless otherwise explicitly limited, the terms ''installation'', ''connection'', ''connection'', ''connector'' should be understood broadly.

[0055] In the utility model, the terms ''one embodiment'', ''some embodiments'', ''example'', ''specific example'' or ''some examples'' etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are contained in at least one embodiment or example of the utility model.

[0056] In the following, the utility model is specifically described through exemplary embodiments.

[0057] The embodiment of the utility model provides a kind of muffler assembly, it is applied to the exhaust system of vehicle, mainly for reducing the exhaust noise of vehicle exhaust system, and the muffler assembly of this embodiment, utilize its structural innovation design, can reduce the damage probability of muffler when vehicle rear collision, and it is favorable to reduce the maintenance cost of vehicle.

[0058] In prior art, with the increase of the amount of possession and the increase of the frequency of use, the situation of vehicle collision accident is more and more, especially in the bad weather such as heavy snow and heavy fog, vehicle is more likely to occur rear-end collision, that is, vehicle is collided from rear.

[0059] At this time, since the muffler in the vehicle exhaust system is usually arranged at the tail of the vehicle body, when the vehicle is rear-impacted, if the impact is slightly large, the muffler is easily impacted and damaged. Once the muffler is damaged, when the vehicle is repaired, the entire muffler needs to be replaced, which undoubtedly increases the repair cost of the vehicle, easily causes complaints of the vehicle owner, and is not conducive to the improvement of the overall use quality of the vehicle.

[0060] In view of this, in order to overcome the deficiencies in the prior art, in the muffler assembly of the embodiment, in combination with Figures 1 to 3 As shown in the figure, the overall design includes the muffler body 100 and the energy-absorbing assembly 200.

[0061] The energy-absorbing assembly 200 is arranged on the muffler body 100 and located at the side of the muffler body 100, and at least when the vehicle is impacted from the rear, i.e. the vehicle is rear-impacted (such as rear-end collision), the energy-absorbing assembly 200 can bear the impact before the muffler body 100 to absorb the impact energy by the deformation of the energy-absorbing assembly 200 itself.

[0062] Therefore, by arranging the energy-absorbing assembly 200 at the side of the muffler body 100, and making the energy-absorbing assembly 200 bear the impact when the vehicle is impacted from the rear, i.e. the vehicle is rear-impacted, and absorb the impact energy by the deformation of the energy-absorbing assembly 200 itself, the embodiment can use the energy-absorbing assembly 200 to bear the impact of rear-impact and absorb the impact energy, reduce the probability of damage of the muffler body, i.e. the body structure of the muffler, and when the vehicle is repaired, only the energy-absorbing assembly 200 needs to be repaired or replaced, so as to reduce the repair cost of the vehicle.

[0063] Based on the above overall introduction, specifically, as an exemplary structure, for the muffler body 100 of the embodiment, still by Figures 1 to 3 , in combination with Figure 4 , it generally includes the inlet pipe 101, the muffling subassembly 102, the first outlet pipe 103, the second outlet pipe 104, the inlet flange 105, and the first lifting hook 106 and the second lifting hook 107.

[0064] The above inlet pipe 101 is the inlet pipeline in the overall muffler assembly, which is used to be connected with the exhaust pipe in the vehicle exhaust system, or in some vehicle models provided with a sub-muffler assembly, the inlet pipe 101 is specifically connected with the sub-muffler assembly in the exhaust system.

[0065] In practical implementation, the intake pipe 101 is generally connected to the exhaust pipe or auxiliary muffler assembly in the exhaust system via the intake flange 105 located at the end of the intake pipe 101 (the end furthest from the muffler sub-assembly 102). In this case, the connection between the intake flange 105 and the exhaust pipe or auxiliary muffler assembly can refer to conventional connection methods in existing vehicle exhaust systems (such as screw connections), and will not be elaborated further here.

[0066] The above-mentioned muffler assembly 102 is the main part of the muffler assembly that plays a role in noise reduction. It generally consists of an outer shell and an internal noise reduction unit installed in the outer shell. The outer shell is usually made of steel sheet (preferably stainless steel), and its interior is hollow to accommodate the noise reduction unit. The noise reduction unit can be, for example, a pipe, a baffle, or a sound-absorbing material installed in the outer shell. Based on the installation of the aforementioned pipes and baffles, noise reduction structures such as expansion chambers and resonance chambers can also be formed in the outer shell to reduce exhaust noise through sound wave reflection and interference.

[0067] It is worth noting that, in actual implementation, the aforementioned exhaust sub-assembly 102 can also refer to the relevant structure of the existing vehicle exhaust system, and will not be elaborated here.

[0068] The first exhaust pipe 103 and the second exhaust pipe 104 are used to discharge the gas after it has been silenced by the muffler assembly 102. The gas discharged by the first exhaust pipe 103 and the second exhaust pipe 104 is generally referred to as "vehicle exhaust".

[0069] It is worth noting that, to ensure exhaust performance, a certain method is typically used on the exhaust manifold assembly 102. Figures 1 to 4 As shown, a first exhaust pipe 103 and a second exhaust pipe 104 are respectively provided at both ends of the exhaust system, providing two exhaust channels. In terms of specific arrangement, the exhaust system sub-assembly 202 is usually transversely placed at the bottom of the vehicle along the left-right direction, with the first exhaust pipe 103 and the second exhaust pipe 104 respectively located at the left and right ends of the exhaust system sub-assembly 202. However, in addition to having both the first exhaust pipe 103 and the second exhaust pipe 104 located at both ends, in some embodiments, based on the overall design requirements of the vehicle model, it is also possible to provide only one exhaust pipe on the exhaust system sub-assembly 102 while meeting exhaust requirements.

[0070] The first hook 106 and the second hook 107 are used to install the muffler assembly in the vehicle. In specific implementation, a first exhaust pipe 103 and a second exhaust pipe 104 are respectively set at both ends of the muffler sub-assembly 102, and the first hook 106 and the second hook 107 can be respectively arranged in the first exhaust pipe 103 and the second exhaust pipe 104.

[0071] Specifically, for example, the first hook 106 can be fixed on the first air outlet pipe 103, and the second hook 107 can be fixed on the second air outlet pipe 104. Generally, the hook and the corresponding air outlet pipe can be connected by welding, and the first hook 106 and the second hook 107 are usually connected together by rubber hanging and the body hook at the bottom of the vehicle.

[0072] It is worth noting that in addition to arranging the first hook 106 and the second hook 107 on the two air outlet pipes respectively, of course, according to the number of air outlet pipes on the muffler assembly 102 or the arrangement position of the body hook at the bottom of the vehicle, the position and number of hooks in the muffler body 100 can be adjusted adaptively, as long as it can meet the installation and arrangement requirements of the muffler assembly at the bottom of the vehicle and can ensure the reliability of the installation of the muffler assembly.

[0073] Continuing to combine the embodiments shown in Figures 1 to 3 In some embodiments, for example, the energy absorption assembly 200 can be arranged on the muffler assembly 102 in the muffler body 100 and connected to the rear side of the muffler assembly 102.

[0074] It should be noted that the rear side of the muffler assembly 102 is the side of the muffler assembly 102 facing the rear of the vehicle. By arranging the energy absorption assembly 200 on the muffler assembly 202 in the muffler body 100 and connecting it to the rear side of the muffler assembly 202, it can be understood that it can take advantage of the larger volume of the muffler assembly 202 to facilitate the arrangement of the energy absorption assembly 200 on the muffler body 100, and also facilitate the protection of the muffler assembly 202 as the main structure of the muffler by the energy absorption assembly 200 to ensure the setting effect of the energy absorption assembly 200.

[0075] In addition, it is worth noting that based on the arrangement of the energy absorption assembly 200 on the side of the muffler body 100, in addition to being arranged on the rear side of the muffler assembly 202, of course, in some other embodiments, a part of the energy absorption assembly 200 is further arranged on the other side (such as the left side and / or the right side) of the muffler body 100. It is also feasible. In this way, by distributing the energy absorption assembly 200 on both sides of the muffler body 100, the muffler body 100 can also be protected when the vehicle is side-impacted (i.e. from the side of the vehicle).

[0076] When the energy-absorbing assembly 200 is arranged on the other side of the muffler body 100, for example, the left side and / or the right side of the muffler body 100, it should be noted that the energy-absorbing assembly 200 arranged on the left and right sides of the muffler body 100 can be arranged in an integrated structure with the energy-absorbing assembly 200 arranged on the rear side of the muffler body 100, or can be arranged independently of the energy-absorbing assembly 200 arranged on the rear side of the muffler body 100, as long as the energy-absorbing assembly 200 can achieve a better protection effect on the muffler body 100 in the vehicle rear collision or side collision.

[0077] Continuing from Figure 3 , and in combination with Figure 5 and Figure 6 , still taking the example of arranging the energy-absorbing assembly 200 on the rear side of the muffler assembly 102, in some embodiments, the energy-absorbing assembly 200, for example, includes a connecting bracket 201 and an energy-absorbing plate 202. And the connecting bracket 201 is connected to the muffler assembly 102, and the energy-absorbing plate 202 is connected to the connecting bracket 201.

[0078] At this time, the energy-absorbing plate 202 is specifically in a plate structure, and by making the energy-absorbing assembly 200 include the connecting bracket 201 and the energy-absorbing plate 202, it can be understood that by using the connecting function of the connecting bracket 201, it can facilitate the connection of the energy-absorbing assembly 200 on the muffler assembly 102, and by using the plate structure of the energy-absorbing plate 202, it can also facilitate its design and manufacturing, which helps to reduce the manufacturing cost.

[0079] In some embodiments, the above-mentioned connecting bracket 201, for example, can be multiple and arranged at intervals, and the energy-absorbing plate 202 is connected to each connecting bracket 201. In this way, the connecting bracket 201 is designed to be multiple and arranged at intervals, which obviously can reduce the volume of the connecting bracket 201 compared to using a single connecting bracket 201, and can facilitate the preparation of the connecting bracket 201, and at the same time, by using multiple connecting brackets 201 arranged at intervals, it can obviously ensure the connection strength between the energy-absorbing assembly 200 and the muffler assembly 102, to ensure the stability of the energy-absorbing assembly 200 arranged on the muffler body 100.

[0080] It should be noted that in specific implementation, in addition to the above-mentioned design of the connecting bracket 201 as multiple and arranged at intervals, of course, in other embodiments, only one connecting bracket 201 is used to achieve the arrangement of the energy-absorbing assembly 200 on the muffler assembly 102, which is also possible, and when only one connecting bracket 201 is used, it can be understood that in order to ensure the stability of the energy-absorbing assembly 200 arranged on the muffler assembly 102, the connecting bracket 201 should generally have a certain extension width, and referring to Figure 5 , the extension direction here is the length direction of the energy-absorbing plate 202.

[0081] by Figure 3 、 Figure 5 、 Figure 6 and continue to combine with Figure 7 As shown in, in some embodiments, still taking the preferred use of multiple connecting brackets 201 as an example, structurally, the above-mentioned connecting bracket 201 can be generally in a "U" - shaped structure, and thus the connecting bracket 201 has a first connecting arm 2011 connected to the top of the muffler sub - assembly 102 and a second connecting arm 2012 connected to the bottom of the muffler sub - assembly 102. At the same time, based on this, a second energy - absorbing cavity S is formed between the connecting bracket 201 and the muffler sub - assembly 102.

[0082] At this time, it can be understood that by making the connecting bracket 201 have a first connecting arm 2011 and a second connecting arm 2012 respectively connected to the top and bottom of the muffler sub - assembly 102, and forming a second energy - absorbing cavity S between the connecting bracket 201 and the muffler sub - assembly 102, it can match the shape characteristics of the muffler sub - assembly 102, facilitate the connection between the connecting bracket 201 and the muffler sub - assembly 102, and ensure the stability of the connection between the two.

[0083] Meanwhile, by using the above - formed second energy - absorbing cavity S, it can also utilize the characteristic of the large structural strength of the cavity, so that the connecting bracket 201 has good structural strength and energy - absorbing ability. In this way, on the one hand, it can ensure the supporting ability of the connecting bracket 201 for the energy - absorbing plate 202. When subjected to a collision impact, the energy - absorbing plate 202 can undergo effective crushing deformation to absorb the collision energy. On the other hand, on the basis of the primary energy absorption of components such as the energy - absorbing plate 202, through the deformation space provided by the second energy - absorbing cavity S, the connecting bracket 201 can achieve sufficient secondary energy absorption, which is conducive to achieving the full absorption of the collision impact ability and better reducing the probability of damage to the muffler body 100.

[0084] In addition, it is worth noting that in specific implementation, the connecting bracket 201 can be made of steel material (such as made of stainless steel). And on the basis that the connecting bracket 201 is connected to the muffler sub - assembly 102 through its two connecting arms, for the muffler sub - assembly 102, for example, its outer shell can be composed of an upper shell 1021 and a lower shell 1022 that are buckled together, and the first connecting arm 2011 in the connecting bracket 201 can be fixedly connected to the upper shell 1021 by welding, and the second connecting arm 2012 is fixedly connected to the lower shell 1022 by welding.

[0085] Still as Figure 5 and Figure 6 and combine with Figure 8 and Figure 9As shown in the drawings, in some embodiments, the energy-absorbing plate member 202 comprises, for example, a first plate body 2021 connected with the connecting bracket 201, and a second plate body 2022 stacked on the first plate body 2021, and a first energy-absorbing cavity Q is formed between the first plate body 2021 and the second plate body 2022.

[0086] In this way, by making the energy-absorbing plate member 202 comprise the first plate body 2021 and the second plate body 2022 stacked together, and making the first energy-absorbing cavity Q formed between the two plate bodies, it is obvious that compared with a single-layer plate body structure, using a double-layer plate body structure stacked together and surrounded by a cavity can significantly increase the structural strength of the energy-absorbing plate member 202 itself, and help to improve the energy-absorbing capacity of the energy-absorbing plate member 202.

[0087] In specific implementation, it should be pointed out that the first plate body 2021 and the second plate body 2022 stacked together can be fixed together by welding, for example. And in order to form the first energy-absorbing cavity Q, it is preferred that, for example, the middle part of the second plate body 2022 in the width direction is bulged to one side away from the first plate body 2021. At this time, the cross section of the second plate body 2022 bulged to one side can be substantially trapezoidal in structure, but in addition to being trapezoidal, it is of course also possible for the cross section of the second plate body 2022 to be arc-shaped, etc. Figure 3 、 Figure 5 、 Figure 6 and Figure 8 and Figure 9 It can be understood that by making the second plate body 2022 bulge to one side, it not only facilitates the formation of the first energy-absorbing cavity Q, but also can increase the structural strength of the second plate body 2022 to some extent, thereby improving the energy-absorbing effect when the second plate body 2022 collapses and deforms.

[0088] It can be understood that by making the second plate body 2022 bulge to one side, it not only facilitates the formation of the first energy-absorbing cavity Q, but also can increase the structural strength of the second plate body 2022 to some extent, thereby improving the energy-absorbing effect when the second plate body 2022 collapses and deforms.

[0089] It is worth noting that in specific implementation, in addition to making the energy-absorbing plate member 202 consist of two plate bodies stacked together, of course, in some other embodiments, the energy-absorbing plate member 202 can also be a single plate body structure, and the first energy-absorbing cavity Q is also formed in the single plate body structure. At this time, the single plate body structure constituting the energy-absorbing plate member 202 can be formed by extrusion, or in addition to extrusion, it can also be prepared by roll forming, etc.

[0090] Based on the energy-absorbing plate member 202 using the first plate body 2021 and the second plate body 2022 stacked together, in some embodiments, the first plate body 2021 and the second plate body 2022 can both be made of aluminum plate, for example.

[0091] At this time, it should be noted that the above-mentioned aluminum plate is also an aluminum alloy plate, and by adopting aluminum plates for the first plate body 2021 and the second plate body 2022, the structure of the muffler body 100 and the connecting bracket 201 can be made of steel, and the aluminum plate has lower rigidity than the steel plate. When the energy-absorbing assembly is subjected to a collision impact, the energy-absorbing assembly 200, especially the energy-absorbing plate 202, is deformed to absorb energy, which can further reduce the probability of damage to the muffler body 100 and improve the application effect of the energy-absorbing assembly 200.

[0092] It is worth noting that in specific implementation, in addition to the energy-absorbing plate 202 having better collapse deformation energy-absorbing effect, of course, by adopting aluminum plates for the first plate body 2021 and the second plate body 2022 of the energy-absorbing plate 202, the aluminum plate has the advantage of low weight, which is beneficial to the lightweight of the muffler assembly and even the whole vehicle.

[0093] In addition, in addition to using aluminum plates, in some other embodiments, of course, the first plate body 2021 and the second plate body 2022 can also be made of magnesium alloy plates. In addition to making the first plate body 2021 and the second plate body 2022 of aluminum plates, of course, only one of the first plate body 2021 and the second plate body 2022 can also be made of aluminum plates. And when only one plate body of the energy-absorbing plate 202 is made of an aluminum plate, preferably, the second plate body 2022 on the outside can be made of an aluminum plate, and the first plate body 2021 can still be made of a steel plate, for example.

[0094] Continuing from Figure 3 , and in combination with Figure 6 and Figure 10 , in some embodiments, the energy-absorbing assembly 200 can further include a resilient buffer 203 arranged between the energy-absorbing plate 202 and the connecting bracket 201, and when the energy-absorbing plate 202 is subjected to a collision impact, the energy-absorbing plate 202 can also extrude the resilient buffer 203 to deform.

[0095] In this way, by arranging the resilient buffer 203 between the energy-absorbing plate 202 and the connecting bracket 201, and making the energy-absorbing plate 202 extrude the resilient buffer 203 to deform when the energy-absorbing plate 202 is subjected to a collision impact, the resilient buffer 203 can be used to reduce the transmission of collision impact energy to the connecting bracket 201 and the muffler body 100, thereby helping to further reduce the probability of damage to the muffler body 100.

[0096] And on the basis of arranging the above-mentioned resilient buffer 203, in some embodiments, the energy-absorbing plate 202 of the present embodiment can be connected to the connecting bracket 201 by a bolt pair.

[0097] At this time, the energy absorption plate 202 is connected to the connecting bracket 201 by the bolt pair. It can be understood that it not only has the advantages of simple connection form, low cost and convenient operation, but also can utilize the characteristics of high connection strength and good connection stability of the bolt pair to ensure the reliability of the connection of the energy absorption plate 202 on the connecting bracket 201. Of course, by utilizing the detachable characteristics of the bolt pair, it can also facilitate the replacement of the energy absorption plate 202 when it is deformed and damaged, and can improve the convenience of maintenance of the energy absorption assembly 200.

[0098] In addition, while the energy absorption plate 202 is connected by the bolt pair, preferably, the elastic buffer 203 can be a rubber piece sleeved on the bolt 204. In this way, the elastic buffer 203 is a rubber piece sleeved on the bolt 204, which can facilitate the arrangement of the elastic buffer 203 between the energy absorption plate 202 and the connecting bracket 201, ensure the reliability of the arrangement of the elastic buffer 203 between the energy absorption plate 202 and the connecting bracket 201, and reduce the design and manufacturing costs of the elastic buffer 203.

[0099] In addition, based on the same energy absorption plate 202 connected to the connecting bracket 201 by the bolt pair, preferably, the nut 205 in the bolt pair can be fixed to the connecting bracket 201. The nut 205 is usually fixed to the connecting bracket 201 by welding, and the nut 205 in the bolt pair is fixed to the connecting bracket 201, which can be understood as further facilitating the connection operation between the energy absorption plate 202 and the connecting bracket 201 on the basis of the bolt pair connection, thereby improving the assembly efficiency of the muffler assembly.

[0100] It is worth noting that in specific implementation, in addition to making the elastic buffer 203 a rubber piece sleeved on the bolt 204, of course, in some other embodiments, the elastic buffer 203 can be a plate or block structure, and is arranged between the energy absorption plate 202 and the connecting bracket 201 by adhesion or clamping.

[0101] In addition to making the elastic buffer 203 a rubber piece, of course, the elastic buffer 203 can also be a structure such as a spring that also has an elastic buffering effect.

[0102] In order to connect the energy absorption plate 202 to the connecting bracket 201 by the bolt pair, in addition to fixing the nut 205 to the connecting bracket 201, in specific implementation, referring to Figures 7 to 9As shown, generally, a connecting hole 2013 is arranged on the connecting bracket 201, a connecting through hole 2021a is arranged on the first plate body 2021, and a mounting hole 2022a is arranged on the second plate body 2022. When assembling the energy-absorbing plate 202, the bolt 204 in the bolt pair is inserted through the mounting hole 2022a, the connecting through hole 2021a, the through hole 2031 of the elastic buffer 203, and the connecting hole 2013, and is connected with the nut 205, and the bolt 204 is tightened by a screwing tool arranged in the mounting hole 2022a.

[0103] It is worth noting that, for the muffler assembly of the present embodiment, based on the implementation forms exemplified in the above embodiments, as a preferred implementation form, the energy-absorbing assembly 200 is still arranged on the muffler body 100. Figures 1 to 10 As shown, it may, for example, include the muffler body 100 and the energy-absorbing assembly 200.

[0104] The energy-absorbing assembly 200 includes a connecting bracket 201 connected to the muffler body 100, an energy-absorbing plate 202 connected to the connecting bracket 201, and an elastic buffer 203 clamped between the energy-absorbing plate 202 and the connecting bracket 201.

[0105] The connecting bracket 201 can be arranged in multiple intervals, the first connecting arm 2011 of each connecting bracket 201 is connected to the top of the muffler body 100, the second connecting arm 2012 of each connecting bracket 201 is connected to the bottom of the muffler body 100, and thus a second energy-absorbing cavity S is formed between each connecting bracket 201 and the muffler body 100.

[0106] The energy-absorbing plate 202 includes a first plate body 2021 and a second plate body 2022 connected together in a stack, a first energy-absorbing cavity Q is formed between the first plate body 2021 and the second plate body 2022, and both the first plate body 2021 and the second plate body 2022 are made of aluminum plate.

[0107] The energy-absorbing plate 202 and each connecting bracket 201 are connected by a bolt pair, and the elastic buffer 203 is a rubber piece that is sleeved on the bolt 204 in the bolt pair, and the nut 205 in the bolt pair is fixedly connected to the connecting bracket 201.

[0108] In the preferred exemplary implementation form of the above muffler assembly, the specific arrangement and arrangement of the connecting bracket 201, the energy-absorbing plate 202, the elastic buffer 203, and the bolt pair, etc. can still be referred to the above embodiments, and in the preferred exemplary implementation form, the connecting bracket 201, the energy-absorbing plate 202, the elastic buffer 203, and the bolt pair, based on the beneficial effects brought by their design, can also be referred to the above embodiments.

[0109] The muffler assembly of the embodiment is designed as above, and the energy-absorbing assembly 200 containing the connecting bracket 201, the energy-absorbing plate 202 and the elastic buffer 203 is arranged on the side of the muffler body 100, so that the energy-absorbing assembly 200 can bear the impact of the rear collision before the muffler body 100, and the energy-absorbing assembly 200 itself can absorb the collision energy. Thus, the energy-absorbing assembly 200 bears the impact of the rear collision and absorbs the collision energy, so that the probability of damage of the muffler body 100 is reduced, and only the energy-absorbing assembly 200 needs to be repaired or replaced when the vehicle is repaired, thereby reducing the repair cost of the vehicle and improving the overall use quality of the vehicle.

[0110] The embodiment of the second aspect of the utility model provides a kind of vehicle, and the exhaust system of the vehicle is provided with the muffler assembly described above.

[0111] In the vehicle of the embodiment, the above-mentioned muffler assembly is the terminal part in the exhaust system of the vehicle, which is generally connected with the upstream exhaust pipe or auxiliary muffler assembly. And, still referring to Figure 1 、 Figure 2 And Figure 4 It is shown that the first hook 106 and the second hook 107 are generally installed to the bottom of the vehicle.

[0112] In addition, still taking the implementation form of the energy-absorbing assembly 200 shown in Figure 1 And Figure 2 As an example, in specific application, when the vehicle collides, especially from the rear, the collision barrier first contacts the energy-absorbing plate 202 in the energy-absorbing assembly 200 and extrudes the energy-absorbing plate 202, and the extruded energy-absorbing plate 202 also extrudes the elastic buffer 203.

[0113] At this time, under the support of the muffler body 100 and the connecting bracket 201, the energy-absorbing plate 202 in the energy-absorbing assembly 200 will collapse and deform under the impact of the rear collision, and absorb the collision energy to reduce the impact force transmitted to the connecting bracket 201. Of course, in addition to the energy-absorbing plate 202, the elastic buffer 203 also absorbs the collision energy, and the connecting bracket 301 also disperses part of the collision energy by transmitting the impact force to the muffler body 100.

[0114] In the case of a small degree of rear collision of the vehicle, generally only the deformation of the energy-absorbing plate 202 in the energy-absorbing assembly 200, or even sometimes only the deformation of the elastic buffer 203, can achieve the absorption and dissipation of the collision energy to avoid damage to the muffler body 100 caused by the collision impact. After the energy-absorbing plate 202 in the energy-absorbing assembly 200 is deformed due to the collision impact, it can be generally disassembled and replaced. It is worth pointing out that even in the case of a slightly larger degree of collision, if the connecting bracket 201 is deformed due to the collision impact, it can be repaired by reshaping or replaced with a new connecting bracket 201 to meet the setting needs of the energy-absorbing plate 202.

[0115] The vehicle of the present embodiment, by setting the muffler assembly as described above, by setting the muffler assembly as described above in the exhaust system of the vehicle, can bear the rear collision impact when the vehicle is rear-impacted by using the energy-absorbing assembly 200 to absorb the collision energy, which can reduce the probability of damage to the muffler body 100, and when the vehicle is repaired, only the energy-absorbing assembly 200 needs to be repaired or replaced, which helps to reduce the repair cost of the vehicle and improve the use quality of the vehicle, and has good practicability.

[0116] The above only describes some embodiments of the present application and is not intended to limit the present application. The technical features or structures in the different embodiments described above can be combined as needed to form other specific technical solutions. For those skilled in the art, the present application can have various modifications and changes.
