As an example, the first bracket 22 and the second bracket 23 can be constructed as sheet metal brackets with thin wall thickness, which are easy to deform under stress. 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 deforms under high and low temperature alternating conditions, the force generated by the deformation of each component on the exhaust pipe 10 will accumulate and be transmitted to the first support 22 and the second support 23. After being subjected to the force, the first support 22 and the second support 23 may slightly deform. Through the slight deformation of the first support 22 and the second support 23, a small part of the force generated by the deformation of the exhaust pipe 10 and accumulated can be absorbed. The remaining force is transmitted to the third support 24. The corresponding connecting mechanism 30 is installed on the third support 24. After being subjected to the force, the third support 24 can slip relative to the corresponding connecting rod 31, thereby absorbing most of the force on the third support 24 and reducing the force transmitted by the third support 24 to the corresponding connecting mechanism 30. At this time, the force transmitted by the third support 24 to the connecting mechanism 30 has been greatly reduced and is less than the force that can be borne at the connecting position of the structural member 2 and the connecting mechanism 30, thereby meeting the strength and durability requirements of the structural member 2 and not causing damage to the structural member 2.
[0056] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The second support 23 can include a first support body 231 and a second support body 232. The first support body 231 and the second support body 232 are connected by bending. The first support body 231 extends in the vertical direction, and the second support body 232 extends in the horizontal direction. The third support 24 includes a third support body 241 and a fourth support body 242. The third support body 241 and the fourth support body 242 are connected by bending.

[0057] The first support body 231 and the second support body 232 are connected by bending, and an included angle can be formed between the first support body 231 and the second support body 232, which can be a right angle or similar to a right angle. The first support body 231 and the second support body 232 can be welded, and the first support body 231 and the second support body 232 can be integrally formed. The first support body 231 can extend in the vertical direction, and the second support body 232 can extend in the horizontal direction. The second support 23 can be configured as an L-shaped structure, so that the structure of the second support 23 is simple, and the connection strength requirement of the exhaust pipe 10 and the structural member 2 can be met. The third support body 241 and the fourth support body 242 are connected by bending, and an included angle can be formed between the third support body 241 and the fourth support body 242, which can be a right angle or similar to a right angle. The third support body 241 and the fourth support body 242 can be welded, and the third support body 241 and the fourth support body 242 can be integrally formed. The third support body 241 can extend in the vertical direction, and the fourth support body 242 can extend in the horizontal direction. The third support 24 can be configured as an L-shaped structure, so that the structure of the third support 24 is simple, and the connection strength requirement of the exhaust pipe 10 and the structural member 2 can be met.
[0058] The first support body 231 can be connected to the first support 22 by bolts, and the second support body 232 can be fixedly connected to the fourth support body 242 by bolts. The corresponding connecting mechanism 30 is installed on the third support body 241, and the third support body 241 is clamped between the first sleeve 33 and the second sleeve 34. By providing the second support 23 including the first support body 231 and the second support body 232 connected by bending, and the third support 24 including the third support body 241 and the fourth support body 242 connected by bending, the first support 22, the second support 23 and the third support 24 can be connected between the exhaust pipe 10 and the structural member 2 by cooperation.
[0059] In some embodiments of the present application, as shown in Figure 1 and Figure 2 At least one mounting bracket 20 can include a fourth support 25 and a fifth support 26, the fourth support 25 and the fifth support 26 are fixedly connected, the fourth support 25 and the corresponding exhaust pipe 10 are fixedly connected, and the corresponding connecting mechanism 30 is installed on the fifth support 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, and the at least one mounting bracket 20 can 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 can be welded with the corresponding exhaust pipe 10, and the fourth bracket 25 can be adapted to the shape of the corresponding exhaust pipe 10. The fifth bracket 26 can be matched and assembled with the corresponding connecting mechanism 30, the fifth bracket 26 can be formed with a corresponding first assembly hole 21, the fifth bracket 26 can be clamped between the corresponding first sleeve 33 and the corresponding second sleeve 34, and the corresponding connecting rod 31 is arranged through the fifth bracket 26 and matched and assembled with the structural member 2. As an example, the fourth bracket 25 can be configured as a sheet metal bracket with a relatively thin wall thickness, and the fourth bracket 25 is easily deformed under stress. A small part of the force generated by the deformation of the exhaust pipe 10 can be absorbed by the slight deformation of the fourth bracket 25.
[0061] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The other end of the connecting rod 31 of the corresponding connecting mechanism 30 mounted on the fifth bracket 26 has a fixing frame 27 for fixed connection with the structural member 2.
[0062] The other end of the connecting rod 31 of the corresponding connecting mechanism 30 mounted on the fifth bracket 26 can have a fixing frame 27, the other end of the corresponding connecting rod 31 away from the limiting flange part 311 can be formed with a threaded part, the other end of the corresponding connecting rod 31 away from the limiting flange part 311 can be matched and assembled with the fixing frame 27, the other end of the corresponding connecting rod 31 away from the limiting flange part 311 can be arranged through the fixing frame 27 and screwed with a nut, so as to realize the fixed connection of the connecting mechanism 30 and the fixing frame 27, and the fixing frame 27 can be fixedly connected with the structural member 2 by bolt connection, clamping or the like. As an example, the fixing frame 27 can be configured as a plate body structure, and the fixing frame 27 can be fixedly connected with the structural member 2 by a plurality of bolts.
[0063] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The fixing frame 27 has a plurality of mounting parts 271, and the plurality of mounting parts 271 are used for connection with the structural member 2.
[0064] The fixing frame 27 can have a plurality of mounting portions 271, which can be distributed along the circumference of the fixing frame 27, and each of the plurality of mounting portions 271 can be used to connect with the structural member 2. The structural member 2 can be formed with a plurality of fixing points, and the plurality of mounting portions 271 can be arranged in one-to-one correspondence with the plurality of fixing points. Each mounting portion 271 has a fixing point arranged in correspondence therewith, so as to realize the connection of the fixing frame 27 with the structural member 2 at multiple positions. By arranging the plurality of mounting portions 271, the force transmitted to the fixing frame 27 can be dispersed, and the force transmitted to the fixing points of the structural member 2 can be reduced, so as to reduce the deformation or even cracking of the fixing points of the structural member 2, and prolong the service life of the structural member 2.
[0065] When the corresponding exhaust pipe 10 deforms under the condition of alternating high and low temperatures, the force generated by the deformation of each component on the exhaust pipe 10 can be accumulated and transmitted to the fourth support 25. The fourth support 25 can be configured as a sheet metal support with a relatively small wall thickness. The fourth support 25 is prone to deformation under force. The slight deformation of the fourth support 25 can absorb a small part of the force generated by the deformation of the exhaust pipe 10 and accumulated. The remaining force is transmitted to the fifth support 26. The corresponding connecting mechanism 30 is installed on the fifth support 26. The fifth support 26 can slide relative to the corresponding connecting rod 31 under force, so as to absorb most of the force on the fifth support 26 and reduce the force transmitted by the fifth support 26 to the corresponding connecting mechanism 30. At this time, the force transmitted by the fifth support 26 to the connecting mechanism 30 has been greatly reduced. 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 the plurality of mounting portions 271, the force received by the fixing frame 27 can be dispersed and transmitted to the plurality of mounting portions 271. The force transmitted to each fixing point on the structural member 2 is further reduced and is less than the force that can be borne by the fixing points of the structural member 2. The strength and durability requirements of the structural member 2 are met, and the structural member 2 is not damaged.
[0066] According to the specific structure of the structural member 2, different structures of the mounting support 20 can be selectively selected, so that the connection of the exhaust device 1 and the structural member 2 meets the strength requirements of the structural member 2.
[0067] According to the vehicle of the second aspect of the present application, the vehicle comprises a structural member 2 and an exhaust device 1. The exhaust device 1 is the exhaust device 1 in the above embodiments. The connecting rod 31 is fixedly connected to the structural member 2.

[0069] In some embodiments of the present application, the structural member 2 is a transmission.
[0070] When the engine of the vehicle is a longitudinal engine, the transmission is generally located below the engine, and the engine and the transmission are arranged in sequence along the length direction of the vehicle. The exhaust pipe 10 can extend along the length direction of the vehicle. According to the arrangement of various components inside the vehicle, the structural member 2 can be the transmission, and the exhaust pipe 10 can be arranged on one side or both sides of the transmission. The transmission can be used to support the exhaust pipe 10.
