[0024] A muffler is a device that allows airflow to pass through while attenuating noise, and it is one of the important components of a motorcycle. Currently, when installing and tightening a muffler, it is generally necessary to use one hand to use a tool to tighten the nut and the other hand to tighten the bolt, which is cumbersome, especially when the space is cramped, or when non-standard tools are required.

[0025] In this regard, refer to Figures 1 to 5 The first aspect of this application provides a muffler mounting structure, including a muffler body 100, a mounting bracket 200 and a nut 300. The mounting bracket 200 is disposed on the muffler body 100 and has a fixing hole 210. One end of the fixing hole 210 has a sliding groove. The nut 300 is engaged in the sliding groove through its opposite side walls and can slide along the sliding groove.

[0026] By providing a groove in the mounting bracket 200 and confining the nut 300 within the groove, the nut 300 can be restricted. When tightening the muffler body 100 with bolts, there is no need to use tools to clamp the nut 300, solving the problem of installation difficulties caused by limited space and improving work efficiency. In addition, the nut 300 can slide along the groove, allowing for fine-tuning and making installation easier.

[0027] The mounting bracket 200 includes a pressure plate 220 with a slotted hole 230 forming a groove. The nut 300 is fitted into the slotted hole 230. This structure facilitates production and improves work efficiency. Furthermore, to ensure the nut 300 is stably fitted into the groove, the depth of the slotted hole 230 must be greater than or equal to half the thickness of the nut 300.

[0028] Furthermore, a limiting part is provided at the end of the strip hole 230 away from the mounting bracket 200 to limit the axial displacement of the nut 300, thereby preventing the nut 300 from dislodging from the strip hole 230 and improving the stability of the nut 300.

[0029] Reference Figures 1 to 4 In this embodiment, a mounting gap 240 is provided between the pressure plate 220 and the mounting bracket 200. The nut 300 is engaged with the slotted hole 230 and extends into the mounting gap 240. Specifically, the nut 300 is a flange nut, with its flange located within the mounting gap 240, and the nut head engaged within the slotted hole 230. By using the nut 300 as a flange nut, the flange of the flange nut can be pressed against the pressure plate 220, thereby achieving tightness of the nut 300 and improving stability.

[0030] Reference Figure 5 In this embodiment, the pressure plate 220 includes a fixing part 250 and a cantilever part 260, with a connecting part 270 between the fixing part 250 and the cantilever part 260. The fixing part 250 is fixedly connected to the mounting bracket 200, and an installation gap 240 is formed between the cantilever part 260 and the mounting bracket 200. By adopting the above mechanism, the flange nut can be loosened and adjusted by moving the cantilever part 260, making the operation simpler. The fixing part 250, the cantilever part 260, and the connecting part 270 are integrally formed by bending or stamping, facilitating the production and processing of the pressure plate 220 and improving work efficiency.

[0031] It is conceivable that the fixing part 250 and the mounting bracket 200 are fixed by welding. Specifically, the flange nut is aligned with the fixing hole 210, and then the pressure plate 220 is welded to the mounting bracket 200. At this time, the nut head of the flange nut is embedded in the strip hole 230, and the cantilever part 260 of the pressure plate 220 presses against the flange nut, so that the mounting bracket 200, the pressure plate 220 and the flange nut form a whole, and then it is fixed to the muffler body 100. The structure is simple and the operation is convenient.

[0032] It should be noted that the pressure plate 220 can also be formed by bending or stamping to form a recessed part. In this case, the strip hole 230 is set in the mounting part, the recessed part forms the mounting gap 240, and the two sides of the recessed part are fixedly connected to the pressure plate 220, thereby realizing the installation of the pressure plate 220.

[0033] Reference Figures 1 to 4 In some embodiments of this application, the mounting bracket 200 is provided with an auxiliary plate 280, which is located on the side of the mounting bracket 200 near the pressure plate 220. A fixing hole 210 passes through the auxiliary plate 280. By providing the auxiliary plate 280, the depth of the fixing hole 210 can be increased, thereby improving the stability of the connection. The fixing hole 210 is configured as an adjustment hole, with its length direction aligned with the length direction of the slide groove. This eliminates the need for precise positioning during installation, reducing installation difficulty and improving installation efficiency.

[0034] A second aspect of this application provides a motorcycle including the muffler mounting structure described in the first aspect of this application.

[0035] The motorcycle described in the second aspect of this application has a sliding groove provided in the mounting bracket 200, and the nut 300 is secured in the sliding groove by the opposite side walls. At this time, the nut 300 can be restricted. When the muffler body 100 is tightened with bolts, there is no need to use tools to tighten the nut 300, which solves the problem of installation difficulties caused by space constraints and improves work efficiency.

[0036] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
