[0002] With societal development, more and more people are using bicycles for exercise and cycling trips. When using bicycles at night or in low-light conditions, riders have reduced visibility, so a headlight is usually needed to illuminate the road in dim light. Current bicycle lights, in order to reduce size and portability, typically encapsulate the battery, circuit board, and LED light source in a single housing. Since LEDs generate a lot of heat when emitting light, it's necessary to minimize heat transfer to the battery to improve safety. Furthermore, cyclists who enjoy long-distance riding often carry smartphones, smartwatches, headphones, and other electronic devices. If these devices run out of power during a ride, it can be a significant inconvenience. Utility Model Content

[0028] This utility model embodiment provides a bicycle headlight that can be used as a portable power source. (See reference...) Figures 1 to 7 The bicycle headlight mainly includes a cylindrical housing 10, a power supply assembly 20, and a light source assembly 30. The cylindrical housing 10 contains a first partition 40 and a second partition 50, which divide the housing into a first accommodating cavity 11, a second accommodating cavity 12, and a third accommodating cavity 13, arranged sequentially. The power supply assembly 20 is assembled in the first accommodating cavity 11, and the light source assembly 30 is assembled in the third accommodating cavity 13 and electrically connected to the power supply assembly 20.

[0029] Specifically, the power supply assembly 20 mainly includes a battery 21 and a main control circuit board 22 electrically connected to each other. The main control circuit board 22 is located within the first accommodating cavity 11 and connected to the first partition 40. The battery 21 is spaced apart from the main control circuit board 22 within the first accommodating cavity 11. A power connector 23 is connected to the main control circuit board 22. A charging window is provided on the side wall of the cylindrical outer shell 10 corresponding to the position of the power connector 23 to expose the power connector 23. A waterproof gasket 24 covering the power connector 23 is fitted on the charging window. The power connector 23 is configured to connect to an external power source to charge the battery 21. The power connector 23 is preferably a Type-C connector.

[0030] Specifically, the light source assembly 30 includes an LED driver board 31 and a lens 32. The LED driver board 31 is connected to the second partition 50, and LED chips 33 are connected to the LED driver board 31. The lens 32 covers the LED chips 33. The light source assembly 30 is electrically connected to the power supply assembly 20 via a connecting trace 34, specifically, the connecting trace 34 electrically connects the LED driver board 31 to the main control circuit board 22.

[0031] The bicycle headlight also includes a charging cable 60 and a charging plug 70 for charging external electronic devices. The cylindrical housing 10 has a connection hole 14, a insertion hole 15, and a receiving groove 16 connecting the connection hole 14 and the insertion hole 15 on its side wall. The connection hole 14 communicates with the first receiving cavity 11, and the insertion hole 15 communicates with the second receiving cavity 12. The charging cable 60 is embedded in the receiving groove 16. The first end of the charging cable 60 passes through the connection hole 14 and is electrically connected to the power supply assembly 20. The charging plug 70 is connected to the second end of the charging cable 60 and inserted into the insertion hole 15. Specifically, the power supply assembly 20 also includes a charging management circuit board 25 electrically connected to the battery 21 and the main control circuit board 22, respectively. The first end of the charging cable 60 passes through the connection hole 14 and is electrically connected to the charging management circuit board 25. The charging plug 70 is preferably a Type-C plug.

[0032] Specifically, the second accommodating cavity 12 is provided with a female socket 121 that is adapted to the shape of the charging plug 70, and the charging plug 70 is inserted into the female socket 121 through the plug hole 15.

[0033] As described above, the bicycle headlight features three sequentially arranged accommodating cavities: a first accommodating cavity 11, a second accommodating cavity 12, and a third accommodating cavity 13, separated within the cylindrical housing 10 by a first partition 40 and a second partition 50. A power supply assembly 20 containing a battery 21 is mounted in the first accommodating cavity 11, and a light source assembly 30 containing an LED driver board 31 is mounted in the third accommodating cavity 13. Because the first accommodating cavity 11 and the third accommodating cavity 13 are isolated from each other by the second accommodating cavity 12, heat dissipated by the light source is reduced from being conducted to the battery 21, improving the safety performance of the headlight. Secondly, the bicycle headlight includes a charging cable 60 and a charging plug 70 for charging external electronic devices. When the rider's electronic devices run out of power during riding, the headlight can act as a portable power source to provide emergency charging, reducing potential inconvenience for the rider. Furthermore, the charging cable 60 is embedded in the receiving groove 16 on the side wall of the cylindrical housing 10, and the charging plug 70 is received in the second receiving cavity 12 through the plug hole 16. The bicycle headlight with this structure has the advantages of compact structure, small size and easy portability.

[0034] Furthermore, in this embodiment, a plurality of supporting ribs 111 are provided on the inner wall of the first accommodating cavity 11. The supporting ribs 111 extend along the length direction of the first accommodating cavity 11 and a stop portion 112 is provided near the first partition 40. A limiting baffle 17 is provided on the side of the first accommodating cavity 11 opposite to the first partition 40. The battery 21 is placed in the accommodating space formed by the plurality of supporting ribs 111 and the limiting baffle 17. By providing the supporting ribs 111 and the stop portion 112, the battery 21 is supported in the middle of the first accommodating cavity 11. Gaps are formed between the battery 21 and the inner walls of the first accommodating cavity 11 and between the battery 21 and the main control circuit board 22, thereby increasing the heat dissipation space of the battery and further improving the safety of the vehicle lights.

[0035] Furthermore, in this embodiment, a heat insulation baffle 35 is provided between the lamp bead driver board 31 and the second partition 50. By providing the heat insulation baffle 35, the heat emitted by the light source is further reduced from being conducted to the battery 21.

[0036] Furthermore, in this embodiment, a rear cover 18 is connected to the limiting baffle 17. The cylindrical outer casing 10 is provided with a switch button 80 connected to the main control circuit board 22, and also with a connecting buckle 90 connected to the bicycle.

[0037] As a preferred embodiment, in this case, the switch button 80 and the connecting buckle 90 are disposed on the upper surface of the cylindrical housing 10. The connecting hole 14, the plug hole 15, and the receiving groove 16 are disposed on the lower surface of the cylindrical housing 10, that is, the charging cable 60 and the charging plug 70 for charging external electronic devices are connected to the lower surface of the cylindrical housing 10. The charging window is disposed on the left side of the cylindrical housing 10; however, in some other embodiments, the charging window may also be disposed on the right side.

[0038] In summary, the bicycle headlight that can be used as a portable power source provided by this embodiment of the invention not only reduces the heat emitted by the light source from being conducted to the battery to improve safety, but also provides emergency charging for the electronic devices carried by the rider.

[0039] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
