[0002] Electric motorcycles, known for their lightness, safety, and affordability, have become popular among consumers and have become widely adopted. Motorcycle side covers are crucial for protecting precision motor components and also serve as heat dissipation mechanisms. When the motorcycle is in motion, heat generated by the motor is transferred to the side covers and then dissipated into the air. However, existing side covers provide inadequate heat dissipation. Furthermore, when the motorcycle is traveling at high speeds, air impacts the side covers, creating turbulence and leading to noise. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a heat dissipation and noise reduction structure for a motorcycle side cover, which can simultaneously improve the heat dissipation and noise reduction performance of the side cover.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved through the following technical solutions:

[0005] A heat dissipation and noise reduction structure for a motorcycle side cover includes a circular cover body with a central hole. A plurality of heat dissipation and noise reduction units are evenly arranged along the circumference of the cover body. The heat dissipation and noise reduction units include a plurality of linear ribs arranged in parallel and at intervals. The ribs of different heat dissipation and noise reduction units have different extension directions. The ribs pass through the corresponding heat dissipation and noise reduction units. The surfaces of the ribs form heat dissipation surfaces, and the gaps between adjacent ribs form air guide grooves.

[0006] In the heat dissipation and noise reduction structure of the motorcycle side cover, the heat dissipation and noise reduction units are evenly arranged along the circumference, which means that the heat dissipation and noise reduction units can be in an overlapping state after the cover body rotates a fixed angle around its center.

[0007] In the above-mentioned heat dissipation and noise reduction structure of a motorcycle side cover, three heat dissipation and noise reduction units are provided, and the angle between the straight lines where the ribs on adjacent heat dissipation and noise reduction units are located is less than 60°. The ribs at this angle form an inclined structure, and when the cover body rotates at high speed, the air guide groove forms a spiral air guide structure with a larger angle.

[0008] In the above-mentioned heat dissipation and noise reduction structure of a motorcycle side cover, the cover body is provided with an outer edge protruding from the cover body surface, the height of the rib is smaller than the height of the outer edge, and one end or both ends of the rib are connected to the inner side of the outer edge.

[0009] In the above-mentioned heat dissipation and noise reduction structure of a motorcycle side cover, unit gaps are provided between adjacent heat dissipation and noise reduction units, and both ends of the ribs are respectively connected to the outer edge or the unit gaps.

[0010] In the above-mentioned heat dissipation and noise reduction structure of a motorcycle side cover, the unit gaps are staggered and distributed in a spiral shape, and the inner sides of the unit gaps form an equilateral triangle.

[0011] In the above-mentioned heat dissipation and noise reduction structure of a motorcycle side cover, a mounting flange is provided on the cover body, and a plurality of radially distributed connecting plates are provided between the outer edge and the mounting flange; and a plurality of mounting holes are provided on the mounting flange.

[0012] In the above-mentioned heat dissipation and noise reduction structure of a motorcycle side cover, the heat dissipation and noise reduction structure is arranged on the end cover and hub cover of the motorcycle. The end cover and hub cover are arranged correspondingly, and their heat dissipation and noise reduction units are also arranged correspondingly.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model provides a heat dissipation and noise reduction structure for a motorcycle side cover, which adopts a plurality of circumferentially arranged heat dissipation and noise reduction units, each of which includes a plurality of parallel and spaced ribs, the ribs increase the surface area of ​​the side cover, thereby enhancing heat dissipation, and air guide grooves are formed between the ribs, which can guide the gas hitting the side cover to flow along the guide grooves to avoid turbulence, thereby achieving a noise reduction effect. At the same time, since the ribs of different heat dissipation and noise reduction units have different extension directions, when the motorcycle is running, the guided wind can form a spiral structure, which is conducive to the discharge of gas; further, the ribs are set to an inclined structure, when the motorcycle is running, the wind discharged by the air guide grooves of the plurality of heat dissipation and noise reduction units can form a spiral structure with a larger angle, which is more conducive to the discharge of gas.

[0022] Compare with Figure 1 and attached Figure 2 A heat dissipation and noise reduction structure for a motorcycle side cover includes a circular cover body 1 with a central hole 2. A plurality of heat dissipation and noise reduction units are evenly arranged along the circumference of the cover body 1. The heat dissipation and noise reduction units include a plurality of linear ribs 3 arranged in parallel and spaced apart. The ribs 3 of different heat dissipation and noise reduction units have different extension directions. The ribs 3 pass through the corresponding heat dissipation and noise reduction units. The surfaces of the ribs 3 form heat dissipation surfaces, and the gaps between adjacent ribs 3 form air guide grooves.

[0023] In this embodiment, the heat dissipation principle of the side cover is: by setting the rib 3 structure to increase the surface area of ​​the side cover, thereby increasing the heat exchange effect between the side cover and the outside world, and the heat generated by the motor can be dissipated to the outside world faster; the noise reduction principle of the side cover is: through the air guide grooves between the ribs 3, the gas that hits the side cover at high speed is made to flow in a directional manner, thereby avoiding turbulence and achieving the effect of noise reduction. At the same time, by setting a plurality of heat dissipation and noise reduction units, and making the ribs 3 have different extension directions, the air guide grooves of the plurality of heat dissipation and noise reduction units also have different extension directions. When the motorcycle is running, the gas that hits the side cover can form a spiral structure and be discharged out of the side cover faster, avoiding being trapped in the air guide groove and re-generating noise; thus, the side cover structure of this embodiment can have the effects of heat dissipation and noise reduction at the same time.

[0024] Preferably, three heat dissipation and noise reduction units are provided, and the angle between the straight lines where the ribs 3 on adjacent heat dissipation and noise reduction units are located is less than 60°. The ribs 3 at this angle form an inclined structure. When the cover body 1 rotates at high speed, the air guide groove forms a spiral air guide structure with a larger angle, thereby extracting the gas faster.

[0025] The cover 1 is provided with an outer edge 4 protruding from the surface of the cover 1. The height of the ribs 3 is less than that of the outer edge 4. One or both ends of the ribs 3 are connected to the inner side of the outer edge 4. By providing the outer edge 4, a protective structure can be formed for the ribs 3.

[0026] In this embodiment, a unit gap 5 is provided between adjacent heat dissipation and noise reduction units, and the two ends of the ribs 3 are respectively connected to the outer edge 4 or the unit gap 5; the shorter ribs 3 on the outside are connected to the outer edge 4 at both ends, and the longer ribs 3 on the inside are connected to the outer edge 4 at one end and the other end to the unit gap 5.

[0027] Furthermore, the unit gaps 5 are staggered and distributed in a spiral shape, and the inner sides of the unit gaps 5 form an equilateral triangle.

[0028] The cover body 1 is provided with a mounting flange 6, and a plurality of radially distributed connecting plates 7 are provided between the outer edge 4 and the mounting flange 6; the mounting flange 6 is provided with a plurality of mounting holes; the connecting plates 7 can simultaneously increase the structural strength of the outer edge 4 and the mounting flange 6.

[0029] The heat dissipation and noise reduction structure is arranged on the end cover of the motorcycle.

[0031] Compare with Figure 3 and attached Figure 4 The heat dissipation and noise reduction structure in Example 2 is substantially the same as that in Example 1, but the heat dissipation and noise reduction structure is provided on the hub cover of the motorcycle.
