The bracket includes: a first structural arm 1, a second structural arm 2, and a bracket body 3. The first structural arm 1 and the second structural arm 2 are fixedly connected to both sides of the bracket body 3. The bracket body 3 is fixedly connected to the vehicle body longitudinal beam 20. Both the first structural arm 1 and the second structural arm 2 extend from both sides of the bracket body 3 toward one side of the muffler can 10.

One end of the second reinforcing structure 6 is fixedly connected to the first structural arm 1, and the other end of the first reinforcing structure 6 is fixedly connected to the bracket body 3. This can enhance the connection strength between the first structural arm 1 and the bracket body 3, thereby improving the overall structural stability and strength of the multi-functional silencer can fixing bracket 30.

[0046] Thus, in this application, by extending the first structural arm 1 and the second structural arm 2 from both sides of the bracket body 3 toward one side of the muffler 10, and forming a muffler installation space between the first structural arm 1, the bracket body 3, and the second structural arm 2, a space is provided for accommodating the muffler 10.

The structure is simple and easy to assemble and disassemble. Furthermore, by providing a first wire harness fixing part 22 on the second structural arm 2, the first wire harness fixing part 22 is used for detachable connection with the wire harness fixing component, thereby achieving the fixation of some wire harnesses inside the vehicle. This increases the utilization of the multi-functional muffler fixing bracket 30 while saving the cost of designing and manufacturing a separate wire harness fixing component.

[0047] In some embodiments, the multi-functional muffler can mounting bracket 30 can be formed by sheet metal stamping, which can save the processing cost of the multi-functional muffler can mounting bracket 30 and facilitate mass production.

[0048] In other embodiments, the first connecting part 11 can be a welding nut, and the second connecting part 21 can be an elongated hole. The silencer 10 is provided with a connecting hole that matches the welding nut and an adjusting hole that matches the elongated hole. By connecting the connecting hole with the welding nut, a positioning reference is provided for the fixed connection of the silencer 10. The adjusting hole is fixedly connected with the elongated hole by bolts, which can absorb the assembly error generated during the assembly of the multi-functional silencer fixing bracket 30 and the silencer 10, thereby reducing the assembly difficulty of the multi-functional silencer fixing bracket 30 and the silencer 10 and improving the assembly efficiency.

[0049] In some embodiments, the support body 3 is provided with at least two connection holes 31, and at least one of the at least two connection holes 31 is a tolerance hole.

[0050] Specifically, the tolerance hole can be an oblong hole.

[0051] Specifically, the longitudinal beam 20 of the vehicle body is provided with fixing holes that cooperate with the connecting holes 31, and the multi-functional muffler can mounting bracket 30 can be fixed to the longitudinal beam 20 of the vehicle body by bolt connection.

[0052] In this embodiment, at least two connecting holes 31 are provided on the bracket body 3, and at least one of the at least two connecting holes 31 is a tolerance hole. The tolerance hole can absorb the assembly error generated during the assembly process of the bracket body 3 and the vehicle longitudinal beam 20, thereby reducing the assembly difficulty of the bracket body 3 and the vehicle longitudinal beam 20.

[0054] In some embodiments, the first structural arm 1 includes a first connecting arm 12 and a second connecting arm 13, and a first connecting portion 11 is disposed on the second connecting arm 13; one side of the first connecting arm 12 is fixedly connected to the bracket body 3, and the first connecting arm 12 extends toward the silencer 10 relative to the bracket body 3; the other side of the first connecting arm 12 is fixedly connected to the second connecting arm 13; a bent structure is formed at the connection between the first connecting arm 12 and the second connecting arm 13, and the bent structure protrudes toward the silencer 10.

[0055] Specifically, the first connecting arm 12, the second connecting arm 13 and the bending structure can be integrally formed, the bending structure protrudes towards the silencer 10, and the bending angle of the bending structure can be 80-135°.

[0056] Specifically, a transition structure can be provided at the bending structure, which can improve the connection strength of the first connecting arm 12 and the second connecting arm 13 and avoid stress concentration at the connection between the first connecting arm 12 and the second connecting arm 13.

[0057] In some embodiments, the transition structure can be a transition rounded corner structure.

[0058] In other embodiments, a bending structure is used to form a 90° bending angle between the first connecting arm 12 and the second connecting arm 13, that is, the first connecting arm 12 is perpendicular to the second connecting arm 13.

[0059] In this embodiment, the first structural arm 1 includes a first connecting arm 12 and a second connecting arm 13. The connection between the first connecting arm 12 and the second connecting arm 13 forms a bent structure. The bent structure protrudes towards the muffler tank 10, thereby increasing the gap between the multi-functional muffler tank fixing bracket 30 and the vehicle body longitudinal beam 20, thus avoiding interference between the muffler tank 10 and the vehicle body longitudinal beam 20.

[0060] In some embodiments, the multifunctional silencer can mounting bracket 30 satisfies at least one of the following features: the first connecting portion 11 includes a positioning hole for passing through a positioning fixing member; the second connecting portion 21 is an elongated hole.

[0061] In some embodiments, the positioning fastener can be a stud. The stud is connected to the positioning hole bolt, thereby fixing one end of the muffler 10 to the stud, thus positioning the installation position of the muffler 10. The other end of the muffler 10 is then fixedly connected to the elongated hole bolt. The elongated hole can adjust the fixed connection position between the muffler 10 and the multi-functional muffler fixing bracket 30. The elongated hole can also accommodate assembly errors generated during the bolt connection process between the muffler 10 and the multi-functional muffler fixing bracket 30, thereby reducing the connection difficulty between the muffler 10 and the multi-functional muffler fixing bracket 30.

[0062] In some embodiments, a transition structure 25 is provided on the second structural arm 2. The second structural arm 2 includes a fixed structural arm 23 and a wire harness structural arm 24. A second connecting part 21 is provided on the fixed structural arm 23. The fixed structural arm 23 and the wire harness structural arm 24 are fixedly connected by the transition structure 25, and there is a planar difference between the fixed structural arm 23 and the wire harness structural arm 24.

[0063] Specifically, the fixed structure arm 23, the wire harness structure arm 24, and the transition structure 25 can be integrally formed, and the transition structure 25 can be an arc-shaped structure, which can enhance the connection strength between the fixed structure arm 23 and the wire harness structure arm 24.

[0064] In other embodiments, the fixed structural arm 23 is provided with a reinforcing rib structure, which can improve the strength of the fixed structural arm 23, thereby improving the overall structural strength of the second structural arm 2 and improving the connection stability of the second structural arm 2.

[0065] Specifically, one end of the transition structure 25 is fixedly connected to the fixed structure arm 23, and the other end of the transition structure 25 is fixedly connected to the wire harness structure arm 24. There is a plane difference between the fixed structure arm 23 and the wire harness structure arm 24. The plane where the fixed structure arm 23 is located is closer to the silencing can 10 than the plane where the wire harness structure arm 24 is located, thereby avoiding interference between the silencing can 10 and the wire harness fixing component.

[0066] In this embodiment, a transition structure 25 is provided on the second structural arm 2, which fixes the fixed structural arm 23 and the wire harness structural arm 24. This creates a planar difference between the fixed structural arm 23 and the wire harness structural arm 24, thus avoiding positional interference between the wire harness fixing component and the muffler 10. At the same time, the wire harness structural arm 24 can fix the wire harness fixing component, thereby fixing part of the wire harness inside the car and improving the neatness of the wire harness layout inside the car.

[0074] Specifically, the third structural arm 4 can be configured to protrude from the side of the support body 3 toward the muffler.

[0075] In this embodiment, by setting a third structural arm 4 and fixing the third structural arm 4 to the bracket body 3, the second wire harness fixing part 41 is set on the third structural arm 4, thereby realizing the detachable connection of the wire harness fixing part through the second wire harness fixing part 41, realizing the fixing of some wire harnesses inside the car, ensuring the neatness of the wire harness inside the car, further increasing the space utilization of the multi-functional muffler can fixing bracket 30, while also saving the cost of designing and manufacturing wire harness fixing parts separately.

[0076] In some embodiments, a limiting notch 42 is also provided on the third structural arm 4, which is used to limit the wire harness fixing component.

[0077] Specifically, the limiting notch 42 is not connected to the second wire harness fixing part 41.

[0078] Specifically, the wiring harness fixing component can be a fuse box to compressor wire branch bracket, which has a snap-fit ​​part and a fixing hole that matches the second wiring harness fixing part 41.

[0079] In this embodiment, the wire harness fixing component is limited by the limiting notch 42, thereby preventing the wire harness fixing component from rotating relative to the third structural arm 4 during the assembly process, which would lead to an unstable fixed connection between the wire harness fixing component and the third structural arm 4.

Furthermore, the tank body fixing member 40 is also provided with a third connecting member and an elastic limiting member 407, and by tightening the two ends of the spring with bolts, the rotation of the silencer tank 10 in the radial direction can be restricted, thereby improving the stability of the connection between the silencer tank 10 and the tank body fixing member 40.
