It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0034] The utility model discloses a heat dissipation device for a headlight of an electric two-wheeled vehicle (hereinafter referred to as the headlight heat dissipation device for convenience of description), Figure 1 and Figure 2As shown, the headlight heat dissipation device includes a heat sink 100, a heat sink bracket 200, a dustproof net 300 and a heat dissipation cover 400. One side of the heat sink 100 is connected to the headlight 500, and the other side is provided with a heat dissipation fan 110 and heat dissipation fins 120. The heat dissipation bracket 200 is used to be connected to the headlight 500 and is arranged around the heat sink 100. The dustproof net 300 is connected to the side of the heat sink 100 away from the headlight 500 and is covered by the heat dissipation fan 110 and the heat dissipation fins 120. The heat dissipation cover 400 is connected to the heat dissipation bracket 200 and is covered by the dustproof net 300. The heat dissipation cover 400 is provided with heat dissipation holes 430. It is understood that during actual operation, heat generated by the lamp 500 and its circuit board is transferred to the heat sink 100. Since the heat sink 100 is provided with heat dissipating fins 120, the heat received by the heat sink 100 is dispersed to the heat sink 120. The rotation of the heat dissipating fan 110 cools the heat sink 120, thereby cooling the lamp 500. This combined heat dissipation method of heat dissipating fins 120 and heat dissipating fan 110 effectively cools the lamp 500 and prevents thermal failure during high-power output of the lamp 500. Since the lamp heat sink is also provided with a dust screen 300 and a heat dissipating cover 400, the probability of external dust entering the lamp heat sink is effectively reduced, and dust that has already entered the lamp heat sink is blown out, thereby effectively preventing contamination of the electronic components within the lamp 500.

[0035] refer to Figure 2 and 4 As shown, the dust screen 300 includes a mesh body 310 and a flange portion 320 disposed around the mesh body 310. The mesh body 310 defines a receiving slot 311 for accommodating the cooling fan 110 and the cooling fins 120. The flange portion 320 is configured to connect to the cooling bracket 200. It will be appreciated that the flange portion 320 is configured to connect to the cooling bracket 200, conveniently and securely securing the dust screen 300 to the cooling bracket 200, thereby ensuring the dustproof effect of the headlight cooling device. The mesh body 310 defines a receiving slot 311 for accommodating the cooling fan 110 and the cooling fins 120. This confines the cooling fan 110 and the cooling fins 120 within a relatively sealed space, further reducing the possibility of external dust affecting the cooling effect or contaminating electronic components. It should be supplemented that, in the embodiment of the present invention, the material and mesh area of the dustproof net 300 can be selected according to actual needs, and the parameters of the dustproof net 300 are not specifically limited here.

[0036] refer to Figure 2 and Figure 5As shown, the heat dissipation cover 400 has a mounting slot 410 corresponding to the mesh portion 310. The mesh portion 310 is mounted in the mounting slot 410. The bottom wall of the mounting slot 410 is provided with at least one heat dissipation hole 430. It is understood that the heat dissipation cover 400 has a mounting slot 410 corresponding to the mesh portion 310. The airflow entering through the air vents provided on the bottom wall of the mounting slot 410 directly contacts the upper ends of the heat dissipation fins 120, achieving maximum heat dissipation efficiency.

[0037] Optionally, the connector passes through the heat dissipation cover 400 and the dust screen 300 in sequence and is connected to the heat dissipation bracket 200 to fix the heat dissipation cover 400 and the dust screen 300 to the heat dissipation bracket 200. It is understood that the heat dissipation cover 400 and the dust screen 300 are installed on the heat dissipation bracket 200 via the same connector. This not only facilitates the installation of the headlight heat dissipation device, but also simplifies the structure of the headlight heat dissipation device, reduces the number of components of the headlight heat dissipation device, and reduces the manufacturing cost of the headlight heat dissipation device.

[0038] refer to Figure 3 、 Figure 4 and Figure 5 As shown, a first connecting column 210 is provided on the heat dissipation cover 400, a connecting hole 211 is provided on the first connecting column 210, a through-hole 321 corresponding to the connecting hole 211 is provided on the dustproof net 300, a second connecting column 420 is provided on the heat dissipation bracket 200, a threaded hole 421 corresponding to the through-hole 321 is provided on the second connecting column 420; the connecting member is a screw, which passes through the connecting hole 211 and the through-hole 321 and is threadedly connected to the threaded hole 421. It is understandable that, in the actual assembly process, it is only necessary to place the flange portion 320 of the dust screen 300 onto the heat sink bracket 200, ensuring that the perforation 321 is arranged correspondingly to the threaded hole 421, and then install the heat sink 400 onto the heat sink bracket 200, and make the heat sink 400 pressed against the flange portion 320, the perforation 321 corresponding to the connection hole 211, and finally the screw is passed through the connection hole 211 and the perforation 321 and threadedly connected to the threaded hole 421, thereby using screws to achieve the connection between the heat sink 400, the dust screen 300 and the heat sink bracket 200, which is convenient for assembly. Optionally, there are multiple connectors, and the connection between the heat sink 400, the dust screen 300 and the heat sink bracket 200 is achieved through multiple connectors, which can improve the connection stability and connection sealing, thereby ensuring the structural reliability and dustproof performance of the headlight heat sink device. Of course, in an alternative embodiment, the connector can also be other connecting structural members such as fixing pins, and is not limited to the screws of this embodiment.

[0039] It should be additionally noted that in other embodiments of the present invention, the dust screen 300 can be connected to the heat dissipation bracket 200 by snapping or welding, and the heat dissipation cover 400 can also be connected to the heat dissipation bracket 200 by other means such as snap connection, and is not limited to the above description.

[0040] refer to Figure 2 As shown, the heat sink 100 includes a heat sink fixing plate 130. One side of the heat sink fixing plate 130 is connected to the vehicle lamp 500, and the other end is provided with a cooling fan 110 and a heat sink fin 120. It will be appreciated that the connection between one side of the heat sink fixing plate 130 and the vehicle lamp 500 increases the contact area between the heat sink 100 and the vehicle lamp 500, facilitating the dissipation of heat generated by the vehicle lamp 500, thereby enhancing the heat dissipation effect of the vehicle lamp heat sink on the vehicle lamp 500.

[0041] Optionally, the heat dissipation fixing plate 130 is bonded to the vehicle lamp 500 via a thermally conductive adhesive layer. This facilitates the dissipation of heat generated by the vehicle lamp 500, thereby enhancing the heat dissipation effect of the vehicle lamp heat dissipation device on the vehicle lamp 500. In the embodiment of the present invention, the thermally conductive adhesive layer is thermally conductive silicone. Of course, the thermally conductive adhesive layer can also be made of other materials, not limited to silicone.

[0042] refer to Figure 2 As shown, the heat dissipation fins 120 are arranged in pairs on the heat dissipation fixing plate 130, and the two paired heat dissipation fins 120 are located on either side of the cooling fan 110. During actual operation, heat generated by the vehicle lamp 500 and its circuit board is transferred to the heat sink 100. Because the heat dissipation fins 120 are provided on the heat sink 100 and are arranged in pairs, and the cooling fan 110 is located between the two heat dissipation fins 120, the cooling fan 110 can effectively cool the heat dissipation fins 120, thereby improving the cooling effect on the vehicle lamp 500. Of course, in other embodiments of the present invention, the number and arrangement of the heat dissipation fins 120 and the cooling fan 110 can be adjusted according to actual needs and are not limited to the above description.

[0043] The present invention also discloses an electric two-wheeled vehicle, comprising a vehicle body, a headlight 500, and the aforementioned headlight heat dissipation device for an electric two-wheeled vehicle. Due to the aforementioned headlight heat dissipation device, the headlight 500 is cooled by a combination of heat dissipation fins 120 and a heat dissipation fan 110, effectively preventing thermal failure during high-power output of the headlight 500. The heat dissipation element 100 is protected and encapsulated by a dust screen 300 and a heat dissipation cover 400, effectively reducing the chance of external dust entering the headlight heat dissipation device, thereby effectively preventing contamination of electronic components within the headlight 500.

[0044] refer to Figure 1As shown, the vehicle lamp 500 has a plurality of mounting ears 510 spaced apart along its outer contour. Mounting members pass through the mounting ears 510 to secure the vehicle lamp 500 to the vehicle body. It will be appreciated that securing the vehicle lamp 500 with multiple mounting members ensures both stable and convenient installation. Mounting members can be selected from connecting structures such as screws and pins, depending on actual needs. Of course, in other embodiments of the present invention, the vehicle lamp 500 can also be attached to the vehicle body through other methods such as adhesive bonding or snap-fit connections.

In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
