[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a vertical air guide channel inside the lamp cover, which is U-shaped. A baffle plate is also installed at the air inlet of the air guide channel. The entire lamp cover and its base are angled. This design not only improves aesthetics but also prevents water or dirt from adhering to the inner wall of the vertical air guide channel. The water or dirt naturally falls off due to gravity and is expelled from the air inlet. This effectively avoids the problem of existing headlights having horizontal air guide holes on the lamp cover to capture airflow during driving. While the airflow carries away heat from the lamp cover, the horizontally positioned air guide holes not only allow airflow in rainy weather but also accumulate dried water and dirt on the inner wall over time, potentially affecting the light transmittance of the lamp cover.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To address the problem in existing technologies where headlights use horizontal air vents on the lens to capture airflow during driving, thus dissipating heat from the lens, but where rainwater allows air to enter, and prolonged use leads to dried water stains and dirt adhering to the inner wall of the vents, potentially affecting the light transmittance of the lens, this embodiment provides the following technical solution:

[0025] A high-efficiency heat dissipation headlight structure includes a lamp cover base 1, a bulb connection base 9 on the lamp cover base 1, a reflector bowl 10 on the bulb connection base 9, and a lamp cover 14 disposed at the front end of the lamp cover base 1. An air inlet 18 is provided at the lower end of the lamp cover 14, and an air guide channel 11 is provided inside the lamp cover 14, connected to the air inlet 18. A baffle 17 is provided at the air inlet 18 position on the lamp cover 14. A fixing block 15 is provided on the lamp cover 14, with a locking block 16 at one end of the fixing block 15. A first connecting plate 2 is provided on the lamp cover base 1 and welded to the lamp cover base 1. A section is provided on the end of the first connecting plate 2 away from the lamp cover base 1. The lampshade base 1 has a first fixing plate 3, which is integrally formed with the first connecting plate 2. The first fixing plate 3 has a slot 4 at the corresponding position of the slot 16, which is connected to the slot 16 in a limiting fit. The first fixing plate 3 has a first bolt hole 5, which is integrally formed with the first fixing plate 3. The lampshade base 1 has a second connecting plate 6 at the lower end, which is integrally formed with the lampshade base 1. The second connecting plate 6 has a second fixing plate 7 at the end away from the lampshade base 1. The second fixing plate 7 has a second bolt hole 8 at both the left and right ends. The lampshade base 1 has a hub 12 at the rear end of the bulb connecting base 9, and the hub 12 has a cable socket 13.

[0026] In this embodiment, please refer to Figures 1-4The staff first installs the bulb on the bulb connection base 9 and uses the threads on the bulb connection base 9 to fix the bulb firmly. Then, the cable is passed through the cable socket 13 on the hub 12 and connected to the bulb. The lampshade 14 and the lampshade base 1 are connected by inserting the clip 16 on the lampshade 14 into the slot 4 on the lampshade base 1. When the lampshade base 1 is installed on the motorcycle, the windshield 17 captures part of the airflow generated during the ride, so that the airflow enters the air guide duct 11 through the air inlet 18. After the airflow enters the air guide duct 11, it will carry away the heat inside the lampshade 14, achieving the purpose of heat dissipation for the lampshade 14. The faster the vehicle speed, the faster the airflow speed and the better the heat dissipation effect. The shape of the entire lampshade 14 and lampshade base 1 is obliquely set. This shape not only makes the appearance more beautiful, but also prevents water stains or dirt from adhering to the inner wall of the vertical air guide duct 11. They will fall naturally from the air inlet 18 due to gravity.

[0027] Working principle: The operator first installs the bulb on the bulb connection base 9 and secures it firmly using the threads on the bulb connection base 9. Then, the cable passes through the cable socket 13 on the hub 12 and connects to the bulb. The lampshade 14 and the lampshade base 1 are connected by inserting the clip 16 on the lampshade 14 into the slot 4 on the lampshade base 1. When the lampshade base 1 is installed on the motorcycle, the windshield 17 captures a portion of the airflow generated during driving, allowing the airflow to enter the air guide duct 11 through the air inlet 18. After entering the air guide duct 11, the airflow carries away the heat inside the lampshade 14, achieving the purpose of heat dissipation for the lampshade 14. The faster the vehicle speed, the faster the airflow speed, and the better the heat dissipation effect. The shape of the entire lampshade 14 and lampshade base 1 is obliquely set. This shape not only makes the appearance more beautiful, but also prevents water stains or dirt from adhering to the inner wall of the vertical air guide duct 11. Due to gravity, the water stains or dirt will fall naturally and be discharged from the air inlet 18.
