[0010] Preferably, the front end of the main body plate is triangular, and the front inner and outer sides of the main body plate are penetrated with a first hollowing hole, which is triangular and located in front of the front fixing holes.
[0011] Preferably, the rear wing is trapezoidal, and second hollow holes are formed through the inner and outer sides of the rear wing, and the second hollow holes are triangular.
[0012] Preferably, a plurality of ventilation slots are formed through the inner and outer sides of the main body plate, and each ventilation slot extends to the lower wing.
[0013] Preferably, the ventilation slots are strip-shaped, and a plurality of ventilation slots are arranged at intervals in the front and rear and are located between the front fixing holes and the rear fixing holes.
[0014] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solutions that:
[0015] This product is composed of a rear wing, a lower wing, an upper wing and a main body plate. It is fixed to the outside of the motorcycle exhaust pipe in a semi-wrapping manner to form an airspace, effectively playing a role in preventing the backseat passengers from being scalded during the running of the motorcycle, eliminating potential safety hazards. At the same time, by setting the front fixing holes and the rear fixing holes, this product can be fixed to the motorcycle with only two screws, which is simple and stable to install, and will not affect the use of the vehicle after installation, bringing convenience to the use.

[0025] Please refer to Figure 1 and Figure 2As shown, it shows the specific structure of the preferred embodiment of the present utility model, which is fixed to the outside of the motorcycle exhaust pipe (not shown in the figure) in a semi-wrapped manner, and includes a main body plate 10.
[0026] At the front end of the main body plate 10, front fixing holes 11 are penetrated through the inner and outer sides, and at the rear end of the main body plate 10, rear fixing holes 12 are penetrated through the inner and outer sides. In this embodiment, the front fixing holes 11 are circular holes to facilitate the installation and fixation by passing screws; the rear fixing holes 12 are circular holes to facilitate the installation and fixation by passing screws. The front end of the main body plate 10 is triangular in shape, and first hollowing holes 13 are penetrated through the inner and outer sides of the front end of the main body plate 10. The first hollowing holes 13 are triangular in shape, and the first hollowing holes 13 are located on the front side of the front fixing holes 11.
[0027] An upper wing 20 extends inwardly and bent from the upper side of the front end of the main body plate 10. The upper wing 20 is a polygonal sheet body, which extends obliquely from front to back.
