The contact surface between the steel wool loop and the mounting bracket 20 and the limiting portion 342 is small, which is conducive to reducing the friction force. When the mounting bracket 20 slides relative to the connecting rod 31, the first elastic pad 35 can avoid abnormal noise.

The second elastic pad 36 can abut against the outer peripheral wall of the sleeve portion 341, so that the end of the sleeve portion 341 facing the bending flange 331 can abut against the bending flange 331, which is conducive to improving the compactness of the first sleeve 33, the second sleeve 34 and the second elastic pad 36. The second elastic pad 36 can be assembled between the bending flange 331 and the mounting bracket 20. The second elastic pad 36 can be limitedly abutted against the bending flange 331 and the mounting bracket 20. The second elastic pad 36 can play a role in reducing the friction between the bending flange 331 and the mounting bracket 20, so that the mounting bracket 20 can more easily slide relative to the connecting rod 31.

As an example, the second elastic pad 36 can be constructed as a steel wool loop, and the contact surface between the steel wool loop and the mounting bracket 20 and the bent flange 331 is small, which is conducive to reducing the friction force. When the mounting bracket 20 slides relative to the connecting rod 31, the first elastic pad 35 can avoid abnormal noise. At the same time, the steel wool loop still has a certain elasticity after being pressed together, and can be deformed to a certain extent after being subjected to force.

The first bracket 22 and the second bracket 23 are easily deformed when subjected to force. The micro-deformation of the first bracket 22 and the second bracket 23 can absorb a small part of the force generated by the deformation of the exhaust pipe 10.

[0055] When the corresponding exhaust pipe 10 is deformed under the alternating high and low temperature conditions, the forces generated by the deformation of the various components on the exhaust pipe 10 will be accumulated and transmitted to the first bracket 22 and the second bracket 23. The first bracket 22 and the second bracket 23 may be slightly deformed after being subjected to the force. The micro-deformation of the first bracket 22 and the second bracket 23 can absorb a small part of the force generated and accumulated by the deformation of the exhaust pipe 10, and the remaining force is transmitted to the third bracket 24. The corresponding connecting mechanism 30 is installed on the third bracket 24. The third bracket 24 can slide relative to the corresponding connecting rod 31 after being subjected to the force, so as to absorb most of the force on the third bracket 24 and reduce the force transmitted from the third bracket 24 to the corresponding connecting mechanism 30. At this time, the force transmitted from the third bracket 24 to the connecting mechanism 30 has been greatly reduced, which is less than the force that can be borne at the connection between the structural member 2 and the connecting mechanism 30, and the strength and durability requirements of the structural member 2 are met, and the structural member 2 will not be damaged.

[0056] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the second bracket 23 may include a first bracket body 231 and a second bracket body 232, the first bracket body 231 and the second bracket body 232 are bent and connected, the first bracket body 231 extends in the vertical direction, and the second bracket body 232 extends in the horizontal direction, the third bracket 24 includes a third bracket body 241 and a fourth bracket body 242, the third bracket body 241 and the fourth bracket body 242 are bent and connected, the third bracket body 241 extends in the vertical direction, and the fourth bracket body 242 extends in the horizontal direction, the first bracket body 231 and the first bracket 22 are fixedly connected, the second bracket body 232 and the fourth bracket body 242 are fixedly connected, and the corresponding connecting mechanism 30 is installed on the third bracket body 241.

[0057] The first bracket body 231 and the second bracket body 232 are bent and connected, and an angle can be formed between the first bracket body 231 and the second bracket body 232, and the angle can be a right angle or similar to a right angle. The first bracket body 231 and the second bracket body 232 can be welded and connected, and the first bracket body 231 and the second bracket body 232 can be integrally formed, the first bracket body 231 can extend in the vertical direction, and the second bracket body 232 can extend in the horizontal direction. The second bracket 23 can be constructed as an L-shaped structure, so that the structure of the second bracket 23 is simple and can meet the connection strength requirements of the exhaust pipe 10 and the structural member 2. The third bracket body 241 and the fourth bracket body 242 are bent and connected, and an angle can be formed between the third bracket body 241 and the fourth bracket body 242, and the angle can be a right angle or similar to a right angle. The third bracket body 241 and the fourth bracket body 242 can be welded and connected, the third bracket body 241 and the fourth bracket body 242 can be integrally formed, the third bracket body 241 can extend in the vertical direction, the fourth bracket body 242 can extend in the horizontal direction, and the third bracket 24 can be constructed as an L-shaped structure, so that the structure of the third bracket 24 is simple and can meet the connection strength requirements of the exhaust pipe 10 and the structural member 2.

By setting the second bracket 23 to include the first bracket body 231 and the second bracket body 232 connected by bending, and the third bracket 24 to include the third bracket body 241 and the fourth bracket body 242 connected by bending, the first bracket 22, the second bracket 23 and the third bracket 24 can be connected by matching and assembling to realize the connection between the exhaust pipe 10 and the structural member 2.

[0059] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, at least one mounting bracket 20 may include: a fourth bracket 25 and a fifth bracket 26 , the fourth bracket 25 and the fifth bracket 26 are fixedly connected, the fourth bracket 25 and the corresponding exhaust pipe 10 are fixedly connected, and the corresponding connecting mechanism 30 is installed on the fifth bracket 26 .

[0060] According to the specific arrangement position of the exhaust pipe 10, the specific structure of the mounting bracket 20 can be adjusted according to the environment. At least one mounting bracket 20 may include a fourth bracket 25 and a fifth bracket 26. The fourth bracket 25 and the fifth bracket 26 are connected. The fourth bracket 25 may be welded and connected to the corresponding exhaust pipe 10. The fourth bracket 25 may be adapted to the shape of the corresponding exhaust pipe 10. The fifth bracket 26 may be assembled with the corresponding connection mechanism 30. The fifth bracket 26 may be formed with a corresponding first assembly hole 21. The fifth bracket 26 may be sandwiched between the corresponding first sleeve 33 and the corresponding second sleeve 34. The corresponding connecting rod 31 is passed through the fifth bracket 26 and assembled with the structural member 2. As an example, the fourth bracket 25 may be constructed as a sheet metal bracket with a relatively thin wall thickness. The fourth bracket 25 is easily deformed after being subjected to force. The micro-deformation of the fourth bracket 25 can absorb the force generated by the deformation of a small part of the exhaust pipe 10.

[0061] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the other end of the connecting rod 31 of the corresponding connecting mechanism 30 installed on the fifth bracket 26 has a fixing bracket 27, and the fixing bracket 27 is used for fixed connection with the structural member 2.

[0062] The other end of the connecting rod 31 of the corresponding connecting mechanism 30 installed on the fifth bracket 26 away from the corresponding limiting flange part 311 may have a fixing frame 27, the other end of the corresponding connecting rod 31 away from the limiting flange part 311 may be formed with a threaded portion, the other end of the corresponding connecting rod 31 away from the limiting flange part 311 may be assembled with the fixing frame 27, the other end of the corresponding connecting rod 31 away from the limiting flange part 311 may be penetrated through the fixing frame 27 and screwed with a nut, so as to achieve a fixed connection between the connecting mechanism 30 and the fixing frame 27, and the fixing frame 27 may be fixedly connected to the structural member 2 by bolt connection, clamping, etc. As an example, the fixing frame 27 may be constructed as a plate structure, and the fixing frame 27 may be fixedly connected to the structural member 2 by a plurality of bolts.

[0063] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the fixing frame 27 has a plurality of mounting portions 271 , and the plurality of mounting portions 271 are all used to be connected to the structural member 2 .

[0064] The fixing frame 27 may have a plurality of mounting portions 271, and the plurality of mounting portions 271 may be distributed along the circumference of the fixing frame 27. The plurality of mounting portions 271 may be used to connect with the structural member 2. The structural member 2 may be formed with a plurality of fixing points, and the plurality of mounting portions 271 may be arranged corresponding to the plurality of fixing points one by one. Each mounting portion 271 has a fixing point arranged corresponding thereto, thereby realizing multiple connections between the fixing frame 27 and the structural member 2. By providing a plurality of mounting portions 271, the force transmitted to the fixing frame 27 can be dispersed, and the magnitude of the force transmitted to the fixing point of the structural member 2 can be reduced, thereby reducing durability problems such as deformation or even cracking at the fixing point on the structural member 2, and extending the service life of the structural member 2.

[0065] When the corresponding exhaust pipe 10 is deformed under the alternating high and low temperature conditions, the forces generated by the deformation of the various components on the exhaust pipe 10 will be accumulated and transmitted to the fourth bracket 25. The fourth bracket 25 can be constructed as a sheet metal bracket with a thin wall thickness. The fourth bracket 25 is easy to deform after being subjected to force. The micro-deformation of the fourth bracket 25 can absorb a small part of the force generated and accumulated by the deformation of the above-mentioned exhaust pipe 10. The remaining force is transmitted to the fifth bracket 26. The corresponding connecting mechanism 30 is installed on the fifth bracket 26. The fifth bracket 26 can slide relative to the corresponding connecting rod 31 after being subjected to force, so as to absorb most of the force on the fifth bracket 26 and reduce the force transmitted from the fifth bracket 26 to the corresponding connecting mechanism 30. At this time, the force transmitted to the connecting mechanism 30 by the fifth bracket 26 has been greatly reduced, and the force received by the connecting mechanism 30 is further transmitted to the fixing frame 27. Since the fixing frame 27 can be connected to the structural member 2 through multiple mounting portions 271, the force received by the fixing frame 27 can be dispersed and transmitted to the multiple mounting portions 271, and the force transmitted to each fixing point on the structural member 2 is further reduced and is less than the force that the fixing points of the structural member 2 can withstand, thereby meeting the strength and durability requirements of the structural member 2 and causing no damage to the structural member 2.

[0066] According to the specific structure of the structural member 2 , a mounting bracket 20 with different structures can be selectively selected, so that the connection between the exhaust device 1 and the structural member 2 meets the strength requirement of the structural member 2 .

[0067] The vehicle according to the second embodiment of the present invention comprises: a structural member 2 and an exhaust device 1 , wherein the exhaust device 1 is the exhaust device 1 in the above embodiment, and a connecting rod 31 is fixedly connected to the structural member 2 .

[0068] The vehicle according to the embodiment of the present application includes a structural member 2 and the exhaust device 1 in the above embodiment. The exhaust device 1 can be fixedly connected to the structural member 2 through a connecting rod 31, which can reduce the magnitude of the force transmitted to the structural member 2, extend the service life of the structural member 2, and help improve the safety of the vehicle.

[0069] In some embodiments of the present invention, the structural component 2 is a transmission.

[0070] When the vehicle's engine is longitudinally mounted, the gearbox is generally located at the rear and lower part of the engine. The engine and gearbox are arranged in sequence along the length of the vehicle. The exhaust pipe 10 of the engine can extend along the length of the vehicle. According to the layout of various components inside the vehicle, the structural member 2 can be the gearbox, and the exhaust pipe 10 can be arranged on one side or both sides of the gearbox. The gearbox can be used to support the exhaust pipe 10.
