[0029] The technical solutions in the present application will be described in detail below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0030] Hereinafter, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features.

[0031] In the related art, the exhaust system includes a muffler and tail pipes connected to both sides of the muffler. The tail pipes communicate with the muffler, and the tail pipe decorative covers are welded to the tail ends of the tail pipes to be exposed to the outside.

[0032] However, during the assembly of the exhaust system, there may be some errors in the installation process for the two tail pipes. These errors will have the following two effects: one is that in the direction from the front of the vehicle to the rear of the vehicle, the positions of the two tail pipes may be different, which may cause the positions of the two tail pipe decorative covers in this direction to be different; two is that in the up-down direction, the positions of the two tail pipe decorative covers may be different. These two ways of influence will affect the appearance effect of the two tail pipe decorative covers, and thus reduce the appearance performance of the vehicle.

[0033] Based on this, the embodiments of the present application provide an exhaust system and a vehicle, which can fine-tune the positions of the tail pipes and the decorative covers during the assembly of the exhaust system, so that the two decorative covers can maintain consistent positions in the direction from the front of the vehicle to the rear of the vehicle, or in the up-down direction. In this way, the overall appearance performance of the vehicle can be improved.

[0034] The embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments.

Wherein, the tail pipe 2221 and the decorative cover 2222 can be welded together, and here, the connecting mode of the tail pipe 2221 and the decorative cover 2222 is not specifically limited.

[0037] It should be noted that the first direction described above can be consistent with the direction from the front to the tail of the vehicle, and the preset plane is a plane perpendicular to the direction from the front to the tail of the vehicle, which can be referred to as the direction in the figure. Figure 1

[0038] In this way, by arranging the first adjusting assembly 23 and the second adjusting assembly 24, not only the position of the decorative cover 2222 in the direction from the front to the tail of the vehicle can be adjusted, but also the position of the decorative cover 2222 in any direction in the preset plane, for example, the up-down direction, can be adjusted. In this way, the consistency of the positions of the two decorative covers 2222 can be maintained, and the overall appearance effect of the vehicle can be improved.

[0039] Further, the opposite sides of the muffler 1 are respectively provided with an inlet pipe 11 and an outlet pipe 12 in communication with the corresponding first exhaust pipe 21, and at a position between the inlet pipe 11 and the outlet pipe 12, the first exhaust pipe 21 is provided with a silencer valve 13, and the flow direction of the gas can be controlled through the arrangement of the silencer valve 13. Specifically, when the silencer valve 13 is in a fully closed state, the flow direction of the gas is first exhaust pipe 21→inlet pipe 11→inside of the muffler 1→outlet pipe 12→first exhaust pipe 21→second exhaust pipe 221→tail pipe 2221; when the silencer valve 13 is in a fully open or half open state, part of the flow direction of the gas is first exhaust pipe 21→inlet pipe 11→inside of the muffler 1→outlet pipe 12→first exhaust pipe 21→second exhaust pipe 221→tail pipe 2221, and the other part of the flow direction of the gas is first exhaust pipe 21→second exhaust pipe 221→tail pipe 2221. In the actual driving process of the vehicle, the opening degree of the silencer valve 13 can be determined according to the actual form, and here, no specific limitation is made.

[0040] ​To realize the adjusting function of the first adjusting assembly 23 to the decorative cover 2222 in the first direction, in some embodiments, the first exhaust pipe 21 has a first plug pipe segment 211, and the second exhaust pipe 221 has a second plug pipe segment 2211, the first plug pipe segment 211 and the second plug pipe segment 2211 are plug-fitted.

[0041] It should be noted that the first exhaust pipe 21 further includes a first pipe body 212 connected with the first plug pipe segment 211, the first pipe body 212 is in communication with the inlet pipe 11 and the outlet pipe 12 of the muffler 1, and the sound reduction valve 13 is arranged on the first pipe body 212; the second exhaust pipe 221 further includes a second pipe body 2212 connected with the second plug pipe segment 2211, and the second pipe body 2212 is arranged closer to the tail pipe 2221 than the second plug pipe segment 2211.

[0042] Further, the first adjusting assembly 23 includes a protruding part 231 arranged on one of the first plug pipe segment 211 and the second plug pipe segment 2211, and a guide groove 25 is arranged on the other one of the first plug pipe segment 211 and the second plug pipe segment 2211, and the protruding part 231 is located in the guide groove 25; wherein the protruding part 231 can slide relative to the guide groove 25 to change the position of the second exhaust pipe 221 in the first direction, that is, to change the position of the outlet 2223 in the first direction.

[0043] In the present embodiment, the first plug pipe segment 211 is located on the inner side of the second plug pipe segment 2211, and the protruding part 231 is arranged on the outer side wall of the first plug pipe segment 211, and the guide groove 25 is arranged on the side wall of the second plug pipe segment 2211.

[0044] Of course, in some other embodiments, the matching mode of the first plug pipe segment 211 and the second plug pipe segment 2211 and the arrangement mode of the protruding part 231 and the guide groove 25 can also be as follows:

[0048] It can be understood that the first adjusting assembly 23 adjusts the position of the second exhaust pipe 221 in the first direction, and therefore the protruding portion 231 should move in the first direction within the guide groove 25, that is, the guide groove 25 extends in the first direction, and in order to facilitate the cooperation between the protruding portion 231 and the guide groove 25, one end of the guide groove 25 is open. As shown in the figure, the end of the guide groove 25 close to the front of the vehicle is open. Figure 2

[0049] That is, during the adjustment of the second exhaust pipe 221, the protruding portion 231 can finally stay at any position of the guide groove 25 in the first direction, as long as the positions of the two exhaust outlets 2223 in the first direction are consistent.

[0050] It can be understood that, since the first plug-in pipe segment 211 and the second plug-in pipe segment 2211 are in a plug-in relationship, if the pipe segment located on the outside has a large deformation amount, the plug-in efficiency between the first plug-in pipe segment 211 and the second plug-in pipe segment 2211 can be improved.

[0051] Based on this, in some optional embodiments, an expansion groove 26 penetrating the side wall is formed on the one of the first plug-in pipe segment 211 and the second plug-in pipe segment 2211 located on the outside. In this way, by providing the expansion groove 26, the deformation amount of the pipe segment located on the outside can be increased, so as to improve the plug-in efficiency between the first plug-in pipe segment 211 and the second plug-in pipe segment 2211.

[0052] In the specific embodiments of the present embodiment, the expansion groove 26 is provided on the second plug-in pipe segment 2211; of course, if the first plug-in pipe segment 211 is located on the outside of the second plug-in pipe segment 2211, the expansion groove 26 can also be provided on the first plug-in pipe segment 211.

[0053] In the present embodiment, the extension direction of the expansion groove 26 is consistent with the first direction, and part of the groove segment of the expansion groove 26 is formed on the second plug-in pipe segment 2211, and the other part of the groove segment of the expansion groove 26 is formed on the second pipe body 2212, and one end of the expansion groove 26 away from the tail pipe 2221 is open.

[0054] Of course, the number of expansion grooves 26 can also be set to be multiple, and the multiple expansion grooves 26 are arranged at intervals in the circumferential direction of the second plug-in pipe segment 2211. Here, the number and shape of the expansion grooves 26 are not limited specifically.

[0055] Please continue to combine Figure 4 and Figure 5 , Figure 4 the sectional view of the partial structure of the exhaust pipe assembly in the exhaust system provided by the embodiments of the present application, Figure 5 is Figure 4 ​A local structure of the position B is enlarged and shown in the figure. In order to realize the quick assembly and disassembly between the first exhaust pipe 21 and the second exhaust pipe 221, in some embodiments, the exhaust pipe assembly 2 further comprises a first clamp 27, which is a flat clamp. The flat clamp is arranged on one of the first plug-in pipe segment 211 and the second plug-in pipe segment 2211 on the outer side, and connects the first exhaust pipe 21 and the second exhaust pipe 221 together. In this embodiment, the flat clamp is arranged on the second plug-in pipe segment 2211.

[0056] In this embodiment, the first clamp 27 comprises a first clamp belt 271 and a first bolt 272, which connects two ends of the first clamp belt 271 together. By tightening the first bolt 272, the first clamp belt 271 can be firmly attached to the outer wall surface of the second plug-in pipe segment 2211. The arrangement of the first clamp 27 can realize the quick connection and disassembly between the first exhaust pipe 21 and the second exhaust pipe 221, which can improve the connection efficiency between the first exhaust pipe 21 and the second exhaust pipe 221, and improve the position adjustment efficiency of the second exhaust pipe 221 in the first direction.

[0057] Specifically, if it is necessary to adjust the position of the second exhaust pipe 221, the first bolt 272 can be loosened first, and then the position of the second exhaust pipe 221, i.e. the positions of the second exhaust pipe 221, the tail pipe 2221 and the decorative cover 2222, can be adjusted by moving the protruding part 231 in the guide groove 25. After the adjustment is completed, the position of the second exhaust pipe 221 in the first direction, i.e. the positions of the second exhaust pipe 221, the tail pipe 2221 and the decorative cover 2222 in the first direction, can be fixed by tightening the first bolt 272.

[0058] Please continue to combine Figure 6 and Figure 7 , Figure 6 the second local structure of the exhaust system provided by the embodiments of the present application, Figure 7 is Figure 4 A local structure of the position C is enlarged and shown in the figure. In order to realize the adjustment of the position of the air outlet 2223 in the preset plane by the second adjustment assembly 24, in some embodiments, the second adjustment assembly 24 comprises a first matching pipe segment 241 and a second matching pipe segment 242 which are matched and connected. The first matching pipe segment 241 is formed on the second exhaust pipe 221, and specifically, the second pipe body 2212 is connected between the second plug-in pipe segment 2211 and the first matching pipe segment 241.

[0059] Further, the second fitting pipe segment 242 is formed on the tail pipe 2221, and specifically, the tail pipe 2221 further comprises a third pipe body 2224, one end of the third pipe body 2224 is connected with the second fitting pipe segment 242, and the other end of the third pipe body 2224 is connected with the decorative cover 2222.

[0060] The second fitting pipe segment 242 can rotate relative to the first fitting pipe segment 241 to change the position of the air outlet 2223 in the preset plane. Figure 4 For example, the direction in the above-mentioned embodiment is taken as an example, that is, the second fitting pipe segment 242 can rotate upward or downward relative to the first fitting pipe segment 241 to change the position of the air outlet 2223 in the up-down direction.

[0061] In order to realize the rotational connection between the first fitting pipe segment 241 and the second fitting pipe segment 242, in some embodiments, the exhaust pipe assembly 2 further comprises a second clamp 28, which is a spherical clamp; the spherical clamp is arranged outside the first fitting pipe segment 241 and the second fitting pipe segment 242 to connect the second exhaust pipe 221 and the tail pipe 2221 together. In this way, the rotational connection between the first fitting pipe segment 241 and the second fitting pipe segment 242 can be realized. By adopting the spherical clamp, the functions of rotational fitting and connection are taken into account, and the connection efficiency between the first fitting pipe segment 241 and the second fitting pipe segment 242 can be improved, and the position adjustment efficiency of the tail pipe 2221 can be improved, that is, the position adjustment efficiency of the air outlet 2223 can be improved.

[0062] The second clamp 28 comprises a spherical second clamping belt 281 and a second bolt 282, the second bolt 282 connects two end portions of the second clamping belt 281 together, and the second clamping belt 281 is clamped outside the first fitting pipe segment 241 and the second fitting pipe segment 242.

[0063] Specifically, when the position of the tail pipe 2221 is adjusted to change the position of the air outlet 2223, the second bolt 282 can be loosened first, and then the tail pipe 2221 is rotated to drive the second fitting pipe segment 242 to rotate relative to the first fitting pipe segment 241, so that the position of the air outlet 2223 in the preset plane can be adjusted.

[0064] It should be noted that the first fitting pipe segment 241 and the second fitting pipe segment 242 are connected by the above-mentioned spherical clamp, and the rotation direction of the second fitting pipe segment 242 relative to the first fitting pipe segment 241 can be any angle, that is, by the spherical clamp, not only the position change of the air outlet 2223 in the preset plane can be realized, but also the position change of the air outlet 2223 in the left-right direction can be realized.

[0065] Further, in order to enable the second fitting pipe segment 242 to rotate relative to the first fitting pipe segment 241, in some optional embodiments, the second fitting pipe segment 242 is clamped between the outer wall surface of the first fitting pipe segment 241 and the inner wall surface of the second hoop setting belt 281 of the spherical hoop; wherein the pipe wall shape of the first fitting pipe segment 241 is adapted to the inner wall surface of the spherical hoop, and the pipe wall shape of the second fitting pipe segment 242 is adapted to the partial wall surface of the spherical hoop. That is, the pipe wall surface of the first fitting pipe segment 241 is a spherical surface completely adapted to the inner wall surface of the second hoop setting belt 281, and the pipe wall surface of the second fitting pipe segment 242 is a partial spherical surface adapted to the inner wall surface of the second hoop setting belt 281. In this way, by limiting the pipe wall shapes of the first fitting pipe segment 241 and the second fitting pipe segment 242, the second fitting pipe segment 242 can be rotated relative to the first fitting pipe segment 241 to adjust the position of the tail pipe 2221, and further adjust the position of the air outlet 2223 in the preset plane.

[0066] The embodiment also provides a vehicle comprising a vehicle frame and the exhaust system 10 in the above embodiment; the first pipe body 212 of the first exhaust pipe 21 is connected with the vehicle frame, specifically, the first pipe body 212 is connected with the longitudinal beam of the vehicle frame. Wherein, the exhaust system 10 has been introduced in the above embodiment, and will not be repeated here.

[0067] In order to realize the connection between the first pipe body 212 and the longitudinal beam, the vehicle provided by the embodiment further comprises a first hook 20, a second hook (not shown in the figure) and a lug (not shown in the figure); the first hook 20 is connected with the first exhaust pipe 21, and the second hook is connected with the vehicle frame; the lug has a first connecting hole through which the first hook 20 passes, and a second connecting hole through which the second hook passes. Wherein, the structure of the second hook can refer to the structure of the first hook 20, and the first hook and the longitudinal beam can be connected together by welding or through threaded fasteners.
