[0060] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] In a first aspect, one of the core concepts of an embodiment of the present invention is to disclose a vehicle frame 1 , the vehicle frame 1 comprises a support beam 11 , the interior of the support beam 11 is hollow to form a receiving cavity, and the receiving cavity is suitable for accommodating a part of the exhaust pipe 2 .

[0062] In the embodiment of the present invention, the frame 1 includes a support beam 11, and the interior of the support beam 11 is hollow to form a receiving cavity, and the receiving cavity is suitable for accommodating a part of the exhaust pipe 2, which can reduce the space occupied by the exhaust pipe 2 in the vehicle. In this way, for a vehicle body with the same width, the space saved by the exhaust pipe can be used to arrange other devices, for example, to expand the space for the battery.

[0063] Furthermore, for new energy vehicles of the same width, since part of the exhaust pipe 2 is arranged in the accommodating space of the support beam 11, the exhaust pipe 2 can save the width of the vehicle in the width direction, and then the width of the frame 1 can be widened, so that a larger space can be formed in the frame 1 for arranging the battery 3, which can increase the expansion space of the battery 3 and the power of the battery 3, thereby extending the vehicle's cruising range.

[0064] Optionally, the support beam 11 is provided with a first penetration hole and a second penetration hole which are spaced apart; the first penetration hole and the second penetration hole are both connected to the accommodating cavity; the first penetration hole and the second penetration hole are suitable for penetrating the exhaust pipe 2, so that part of the exhaust pipe 2 can be accommodated in the accommodating cavity of the support beam 11, thereby improving the reliability of reducing the space occupied by the exhaust pipe 2.

[0065] Specifically, the shapes and sizes of the first penetration hole and the second penetration hole can be set with reference to the exhaust pipe 2 to facilitate passing through the exhaust pipe 2 .

[0066] In the second aspect, an embodiment of the present invention further discloses an exhaust pipe assembly, which may include an exhaust pipe 2 and the above-mentioned frame 1; a portion of the exhaust pipe 2 is arranged in the accommodating cavity of the support beam 11 to reduce the space occupied by the exhaust pipe 2.

[0067] Optionally, the support beam 11 is provided with a first through hole and a second through hole arranged at intervals, and the first through hole and the second through hole are both connected to the accommodating cavity; one end of the exhaust pipe 2 extends out of the support beam 11 through the first through hole, and the other end of the exhaust pipe 2 extends out of the support beam 11 through the second through hole.

[0068] In an embodiment of the present invention, part of the exhaust pipe 2 can be arranged in the accommodating cavity of the support beam 11 of the frame 1, which can reduce the space occupied by the exhaust pipe 2 in the vehicle. The space saved by the exhaust pipe 2 can be used to arrange the battery 3, which can increase the expansion space of the battery 3 and increase the power of the battery 3, thereby extending the cruising range of the vehicle.

[0069] Specifically, the exhaust structure assembly refers to a system for collecting and discharging exhaust gas, and the exhaust structure assembly includes an exhaust pipe 2 for transmitting gas. The exhaust pipe 2 has an inlet end and an outlet end, the inlet end is suitable for introducing gas, and the outlet end is suitable for discharging gas.

[0070] Optionally, the structural assembly may further include a catalyst assembly 7, which may be connected to the air intake end of the exhaust pipe 2, so that the catalyst assembly 7 may first improve the exhaust gas to reduce the concentration of pollutants in the exhaust gas, and then discharge the exhaust gas through the exhaust pipe 2.

[0071] Specifically, the vehicle includes an engine assembly, and one end of the catalyst assembly 7 away from the exhaust pipe 2 can be connected to the engine assembly to effectively improve the exhaust gas generated by the engine assembly. Figure 1 As shown, the catalyst assembly 7 can be arranged on the right side of the engine assembly.

[0072] Optionally, the structural assembly may further include a muffler assembly 8, which may be connected to the exhaust end of the exhaust pipe 2, thereby reducing exhaust noise and allowing high-temperature exhaust gas to be discharged safely and effectively.

[0073] Specifically, the overall structure of the exhaust pipe 2 can be arranged along the direction of the vehicle frame 1. Figure 1 As shown, the catalyst assembly 7 can be arranged at the left end of the exhaust pipe 2, and the muffler assembly 8 can be arranged at the right end of the exhaust pipe 2.

[0074] Specifically, in the embodiment of the present invention, the diameter and shape of the exhaust pipe 2 are not specifically limited, as long as the exhaust back pressure required by the engine can be achieved.

[0075] In an embodiment of the present invention, part of the exhaust pipe 2 can be arranged in the accommodating cavity of the support beam 11, and both ends can extend out of the support beam 11, so that at least part of the exhaust pipe 2 can be placed in the accommodating cavity inside the support beam 11. The support beam 11 can be a longitudinal beam of the frame 1, which can reduce the lateral space occupied by the exhaust pipe 2. The space saved by the exhaust pipe 2 can be used to arrange the battery 3, which is beneficial to increase the capacity of the battery 3, extend the vehicle's cruising range, and enhance product competitiveness.

[0076] Optionally, the support beam 11 may be provided with a first through hole and a second through hole arranged at intervals, so that one end of the exhaust pipe 2 may extend out of the support beam 11 through the first through hole, and the other end of the exhaust pipe 2 may extend out of the support beam 11 through the second through hole.

[0077] Specifically, the shape of the cross section of the exhaust pipe 2 perpendicular to its length direction can be circular, square, elliptical or irregular, etc. The sizes of the first penetration hole and the second penetration hole are both larger than the area of ​​the cross section of the exhaust pipe 2 perpendicular to its length direction, so that the exhaust pipe 2 can pass through smoothly.

[0078] In the embodiment of the present invention, taking the exhaust pipe 2 as a rotating body as an example, the first penetration hole and the second penetration hole can both be circular holes. The diameter of the first penetration hole can be 16mm, 19mm, 20mm, 21mm or 25mm larger than the outer diameter of the exhaust pipe 2, and the diameter of the second penetration hole can be 16mm, 19mm, 20mm, 21mm or 25mm larger than the outer diameter of the exhaust pipe 2, so as to facilitate the exhaust pipe 2 to pass through smoothly.

[0079] Optionally, the exhaust pipe 2 may include a second connecting pipe 22, the shape of which may be adapted to the support beam 11, so as to facilitate setting a portion of the second connecting pipe 22 inside the support beam 11, thereby avoiding the second connecting pipe 22 squeezing the inner wall of the support beam 11 and causing stress concentration on the support beam 11.

[0080] Furthermore, the outer wall of the second connecting pipe 22 is spaced apart from the inner wall of the supporting beam 11 , which can reduce the force exerted by the exhaust pipe 2 on the supporting beam 11 .

[0081] Optionally, the exhaust pipe 2 may include a first connecting pipe assembly 21, a second connecting pipe 22 and a third connecting pipe assembly 23 which are connected and communicated in sequence; the end of the first connecting pipe assembly 21 away from the second connecting pipe forms an air inlet end, and the end of the third connecting pipe assembly 23 away from the second connecting pipe forms an air outlet end; at least a portion of the second connecting pipe 22 is arranged in the accommodating cavity of the support beam 11.

[0082] In an embodiment of the present invention, the exhaust pipe 2 includes a first connecting pipe assembly 21, a second connecting pipe 22 and a third connecting pipe assembly 23 connected in sequence, so that the exhaust pipe 2 can adopt a segmented design, which can improve the convenience of assembling the exhaust pipe 2 and the support beam 11.

[0083] Specifically, in the process of assembling the exhaust pipe 2 and the support beam 11, the second connecting pipe 22 and the support beam 11 can be assembled first, and then the second connecting pipe 22 can be connected to the first connecting pipe assembly 21 and the third connecting pipe assembly 23 respectively. Since the second connecting pipe 22 is small in size, the difficulty of assembling the second connecting pipe 22 and the support beam 11 is reduced. Specifically, the welded frame 1 needs to enter the electrophoresis tank for electrophoresis and be dried in a high temperature chamber at 200°C for 30 minutes. During the electrophoresis process, the two ends of the second connecting pipe 22 can be blocked first to prevent the electrophoresis paint from entering the second connecting pipe 22 and avoid contamination of the interior of the second connecting pipe 22.

[0084] Specifically, the first connecting pipe assembly 21, the second connecting pipe 22 and the third connecting pipe assembly 23 are connected in sequence to facilitate exhaust.

[0085] In some optional embodiments, the exhaust structure assembly may further include a vibration damper 4; the second connecting pipe may be connected to the inner wall of the support beam 11 via the vibration damper 4, so that the vibration damper 4 can effectively block the vibration transmitted from the engine and the excitation of the wall of the exhaust pipe 2 caused by the exhaust airflow, thereby avoiding the vibration being transmitted to the frame 1 and causing the vibration of the vehicle to deteriorate, thereby improving the riding comfort.

[0086] Furthermore, since part of the second connecting pipe is arranged in the accommodating cavity of the support beam 11, the corresponding vibration damping member 4 can be arranged in the support beam 11, so that the partial structure in the vehicle is compact, does not affect the arrangement space of the battery 3, and is more practical.

[0087] Optionally, the vibration damper 4 may include a flexible portion 41 , which is connected between the outer wall of the second connecting pipe and the inner wall of the support beam 11 . The flexible portion 41 may buffer and absorb vibration, and effectively prevent the vibration from being transmitted to the frame 1 .

[0088] Specifically, the flexible portion 41 is connected between the second connecting pipe and the support beam 11 to support and fix the second connecting pipe and to play a vibration isolation role, thereby isolating the vibration of the exhaust pipe 2 from being transmitted to the frame 1 and reducing the vibration of the frame 1 .

[0089] Specifically, by adjusting the thickness and hardness of the flexible portion 41, the vibration isolation effect of the flexible portion 41 can be adjusted, while ensuring that the exhaust pipe 2 vibrates within a smaller range. In this way, the layout space of the exhaust pipe 2 can be reduced as much as possible to achieve a compact layout.

[0090] Furthermore, the vibration damper 4 may also include a connecting portion 42 integrally formed with the flexible portion 41 , and the connecting portion 42 is welded and fixed to the inner wall of the support beam 11 , which can effectively ensure the reliability and stability of the connection between the vibration damper 4 and the support beam 11 .

[0091] Optionally, the flexible portion has a first buckling portion, the connecting portion has a second buckling portion, and the second buckling portion and the first buckling portion are buckled and connected, so that the connection between the flexible portion and the connecting portion is more stable, which can improve the stability of the overall structure of the vibration damping member 4.

[0092] Furthermore, one of the first buckling portion and the second buckling portion is a groove, and the other is a convex structure, and the convex structure is accommodated in the groove, which can improve the reliability of the buckling between the first buckling portion and the second buckling portion.

[0093] Specifically, the connection part 42 can be a metal part, so as to realize welding and fixing of the connection part 42 to the inner wall of the support beam 11. The flexible part 41 can be a structure with flexible characteristics such as a plastic part or a rubber part, and the flexible part 41 and the connection part 42 can be processed into an integrated structure by injection molding or vulcanization process.

[0094] Specifically, the second buckling portion may be prepared on the connecting portion first, and then the first buckling portion buckled with the second buckling portion may be prepared during the injection molding or vulcanization stage.

[0095] Specifically, the shape of the connection part 42 can be plate-shaped, block-shaped or skeleton-shaped. In a specific embodiment, the connection part 42 is a plate-shaped structure made of QSTE420 with a thickness of 2 mm, and the material of the flexible part 41 is a rubber pad of high-temperature resistant silicone rubber, and the working temperature of the silicone rubber needs to be 180°C, wherein the two can be formed by vulcanization. In another specific embodiment, the material of the connection part 42 can be iron, and the material of the flexible part 41 is plastic, and the two can be integrally formed by injection molding.

[0096] Specifically, the connecting portion 42 and the flexible portion 41 are integrally formed, so that the overall structural stability of the vibration damper 4 is better. The connecting portion 42 is welded and fixed to the inner wall of the support beam 11, so that the connection stability between the connecting portion 42 and the support beam 11 is better, thereby achieving the connection stability between the vibration damper 4 and the support beam 11.

[0097] Specifically, the connection portion 42 can be directly welded to the inner wall of the support beam 11, or, as Figure 3As shown, the adapter plate 43 may also be welded to the inner wall of the support beam 11, for example, the connection portion 42 is first welded to the adapter plate 43, and then the adapter plate 43 is welded to the inner wall of the support beam 11. Specifically, the adapter plate 43 may play a role in fixing and supporting the vibration damping member 4 and the exhaust pipe 2, and may also play a role in strengthening the support beam 11. Among them, the strength of the support beam 11 may be improved by strengthening the structural strength of the connection portion 42 or the adapter plate 43.

[0098] Specifically, the support beam 11 may be formed by welding a plurality of stamping plates. During the processing, the exhaust pipe 2 may be firstly welded to the stamping plates through the vibration damping member 4 , and then the stamping plates may be welded to form the support beam 11 .

[0099] Specifically, the exhaust pipe 2 and the support beam 11 are rigidly connected by the vibration damping member 4 and cannot be disassembled. During the welding process, since the welding temperature is relatively high, even reaching above 1000°C, the flexible portion 41 of the vibration damping member 4 needs to be heat-insulated to prevent the flexible portion 41 from being damaged during welding.

[0100] In other optional embodiments, the second connecting pipe may be provided with a first limiting structure, and the flexible portion 41 may be provided with a second limiting structure 52. The second limiting structure 52 cooperates with the first limiting structure to improve the reliability of the connection between the flexible portions 41 and the flexible portions 41, so that the flexible portion 41 can block the exhaust pipe 2 from transmitting vibration to the vehicle frame 1.

[0101] Optionally, one of the first limiting structure and the second limiting structure 52 can be a limiting groove, and the corresponding other can be a limiting protrusion, and at least a part of the limiting protrusion is embedded in the limiting groove, so that one of the first limiting structure and the second limiting structure 52 can be at least stuck in the other, so as to ensure the reliability of the connection between the second connecting tube and the flexible part 41. Moreover, the limiting groove can play a avoiding role for the limiting protrusion, which can reduce the occupied space at the connection between the second connecting tube and the flexible part 41 and reduce the difficulty of layout.

[0102] Specifically, in the embodiment of the present invention, there is no specific limitation on the depth of the limiting groove, which can be selected according to actual needs.

[0103] Specifically, the flexible portion 41 is a flexible member, which can clamp the second connecting pipe and limit the second connecting pipe in the axial and radial directions.

[0104] Specifically, Figure 4 As shown, the flexible portion 41 is provided with an arc groove structure, that is, the second limiting structure 52 is an arc groove, and the arc groove is a circular arc segment larger than one-half, so as to clamp the second connecting pipe and better limit the radial position of the second connecting pipe.

[0105] Specifically, the first limiting structure is a limiting groove, and the corresponding second limiting structure is a limiting protrusion, so that the exhaust pipe 2 can also avoid the vibration damping member 4 to adapt to the situation where the internal space of the support beam 11 is limited.

[0106] Optionally, the second connecting tube and the flexible portion 41 may be fastened together by snap fastening or the like.

[0107] In some other embodiments, there may be multiple vibration dampers 4, and the multiple vibration dampers 4 may be spaced apart along the length direction of the second connecting pipe, so that the multiple vibration dampers 4 may cooperate with multiple positions of the flexible member to effectively block the vibration of the exhaust pipe 2.

[0108] Specifically, the plurality of vibration damping members 4 may be arranged at intervals or not at intervals, which may be selected according to actual conditions, and the embodiment of the present invention does not specifically limit this. In addition, the embodiment of the present invention does not limit the specific number of vibration damping members 4 either.

[0109] In some embodiments, the number of the vibration damper 4 may also include one, and the vibration damper 4 may extend along the extension direction of the second connecting pipe to increase the contact area with the second connecting pipe to more reliably block the vibration of the exhaust pipe 2 from being transmitted to the vehicle frame 1.

[0110] Optionally, the exhaust structure assembly may further include a heat insulating member 6, which may be disposed between the second connecting pipe 22 and the inner wall of the support beam 11, and is suitable for blocking the heat of the second connecting pipe 22 from being transferred to the support beam 11. In this way, when the internal space of the support beam 11 is limited, the problem of heat damage caused by the exhaust pipe 2 to the frame 1 and the battery pack assembly and other peripheral parts can be solved.

[0111] Specifically, the heat insulating member 6 may be a cylindrical structure, and the heat insulating member 6 may be sleeved on the second connecting pipe, so that the heat insulating member 6 may block heat along the circumference of the second connecting pipe 22, and the heat insulating effect is better. Further, the heat insulating member 6 may be sleeved on the entire second connecting pipe, or may be sleeved on only part of the second connecting pipe. In the embodiment of the present invention, the thickness and length of the heat insulating member 6 are not specifically limited, and may be selected according to actual needs.

[0112] Specifically, the heat insulating member 6 can be made of heat insulating materials, such as heat insulating felt, polyurethane or aerogel, etc. Among them, aerogel has a good heat insulation rate in the temperature range of 100 to 1000°C. When the heat insulating member 6 is made of aerogel, the surface temperature of the exhaust pipe 2 can be quickly reduced to a reasonable range in a short time. Moreover, the layout space requirement of aerogel is relatively low, which can reduce the difficulty of arranging the heat insulating member 6.

[0113] The thermal insulation member 6 can be a hard structural member or a soft structural member. When the thermal insulation member 6 is a soft structural member, the thermal insulation member 6 can be used in conjunction with a support member. The thermal insulation member 6 can be fixed to the outer wall of the exhaust pipe 2 through the support member to improve the reliability of the thermal insulation member 6 being wrapped around the exhaust pipe 2 and fixed relative to the exhaust pipe 2.
