Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle lighting technology, and in particular to a bicycle headlight. Background Technology
[0002] Most existing bicycle headlights are secured using clips or screws. While clips allow for quick engagement, disassembly requires prying tools, which can easily cause wear or even breakage of the housing edges. Screws, on the other hand, require screwdrivers, making installation and removal cumbersome, especially when riding outdoors. The lack of specialized tools can be extremely inconvenient if the headlight needs to be temporarily removed for charging or maintenance. Furthermore, some headlight clamping components lack anti-slip and shock-absorbing designs. When riding on bumpy roads, the impact of vibrations can cause the internal connections to loosen, ultimately affecting the lifespan of the headlight. Utility Model Content
[0003] To address the technical problems existing in the background art, this utility model proposes a bicycle headlight.
[0004] This utility model discloses a bicycle headlight, comprising a lower housing and an upper housing that are interlocked. The bottom end of the lower housing is provided with an upwardly arched clamping groove, and a clamping plate is rotatably connected to it through a pin and a pin hole. A torsion spring is sleeved on the outside of the pin. The two ends of the torsion spring abut against the lower housing and the middle part abuts against the clamping plate. The end of the clamping plate is provided with an arc-shaped clamp that is symmetrical to the clamping groove. Both the arc-shaped clamp and the clamping groove are fixed with shock-absorbing pads with anti-slip textures.
[0005] Furthermore, a battery and a circuit board are installed inside the lower housing, and a charging interface is integrated on the circuit board. A charging hole is opened at the bottom of the lower housing and the shock-absorbing pad, and the charging end of the charging interface extends to the outside of the lower housing through the charging hole.
[0006] Furthermore, a push-button switch is installed inside the upper housing, and a keycap is embedded in the top of the upper housing. The keycap corresponds to the push-button switch, and the keycap can contact the push-button switch when pressed.
[0007] Furthermore, a solar panel is embedded in the top of the upper housing to charge the bicycle headlight when riding outdoors.
[0008] Furthermore, LED beads are installed inside the lower housing, and a horn-shaped reflector is installed on one side of the LED beads to reflect the light emitted by the LED beads toward the direction of the bicycle's movement.
[0009] Furthermore, the lens is fixed to the openings at the front ends of the lower housing and the upper housing by retaining rings, and the lower housing, the upper housing, and the retaining rings are connected by threads to lock and fix the lens together.
[0010] Furthermore, the pin includes a first pin and a second pin, both of which are inserted into pin holes, and the adjacent ends of the first pin and the second pin are respectively provided with matching internal threads and threaded posts.
[0011] The beneficial effects of this utility model are as follows: By cooperating with the arc-shaped clamp of the clamping plate through the clamping groove at the bottom of the lower housing, the bicycle handlebars can be quickly clamped and disassembled under the action of the torsion spring, without the need for professional tools such as pry bars and screwdrivers. This solves the problems of cumbersome disassembly and assembly and easy damage to parts caused by traditional buckle or screw fixing methods. At the same time, the anti-slip and shock-absorbing pads on the surface of the arc-shaped clamp and the clamping groove can enhance the clamping stability, buffer the impact of riding bumps, prevent the internal connection structure from loosening due to vibration, and extend the service life of the lamp.

[0014] Reference Figure 1-7This utility model proposes a bicycle headlight, including a lower housing 1 and an upper housing 2. The lower housing 1 and the upper housing 2 are connected by a snap-fit connection. During assembly, the snap-fit structures on the edges of the two are aligned and pressed to form a sealed cavity to protect the internal components. The clamping plate 3 is rotatably connected to the pin hole of the lower housing 1 through a pin shaft. The pin shaft consists of a first pin shaft 4 and a second pin shaft 5. The two are fixed by screwing the internal threads at their ends into the threaded post to ensure connection stability. A torsion spring 6 is sleeved on the outside of the pin shaft. Its two ends abut against the inner wall of the lower housing 1, and its middle part abuts against the clamping plate 3, so that the clamping plate 3 always maintains an upward clamping force. The arc-shaped clamp of the clamping plate 3 is symmetrically arranged with the clamping groove 101 of the lower housing 1. Shock-absorbing pads 7 with anti-slip texture are pasted on the surfaces of both. The torsion spring elasticity achieves a stable clamping of the bicycle handlebars. The shock-absorbing pads can buffer riding vibrations and prevent slippage. The lower housing 1 houses the battery 8 and circuit board 9. The battery 8 is connected to the circuit board 9 via wires to power the entire device. The circuit board 9 integrates a charging interface 10. The lower housing 1 and the bottom of the shock-absorbing pad 7 have corresponding charging holes. The charging end of the charging interface 10 extends to the outside through the hole for easy charging via a data cable. The top of the upper housing 2 has a solar panel 13 embedded in it. Its output end is connected to the circuit board 9 via wires. It can absorb light energy and convert it into electrical energy to replenish the battery 8 when riding outdoors. The upper housing 2 has a push-button switch 11 installed inside, and a keycap 12 is embedded in the corresponding position on the top. Pressing the keycap 12 can trigger the push-button switch 11 to turn the light on and off and switch modes. The lower housing 1 has an LED bead 14 installed at the front end, and a horn-shaped light cup 15 is fixed on one side. The inner wall of the light cup is made of a highly reflective material, which can concentrate the scattered light emitted by the LED bead 14 and reflect it in the direction of the bicycle's movement, thereby enhancing the concentration of lighting. The lens 16 is fixed at the front opening of the lower housing 1 and the upper housing 2 by a retaining ring 17. The retaining ring 17 is screwed into the thread on the edge of the housing to tightly clamp the lens 16 at the opening, which serves to prevent dust and water and diffuse light.
[0015] When installing the headlight, first pull the clamp 3 outward by hand. At this time, the clamp 3 rotates around the pin, the torsion spring 6 is compressed and accumulates elasticity. Align the position of the bicycle handlebars where it needs to be installed with the groove 101 of the lower housing 1, and ensure that the handlebars are between the groove 101 and the arc-shaped clamp of the clamp 3. Slowly release the clamp 3. The torsion spring 6 returns to its deformation and drives the clamp 3 to tighten towards the groove 101 until the arc-shaped clamp and the shock-absorbing pad 7 on the surface of the groove 101 are tightly attached to the handlebars. Gently shake the headlight to check if it is stable. If it is loose, you can fine-tune the position of the handlebars and re-clamp it. The anti-slip textured shock-absorbing pad 7 will increase the friction and prevent it from falling off due to vibration during riding. The same principle applies to disassembly. When riding outdoors in bright sunlight, the headlight battery 8 can be charged via the solar panel 13. When it is necessary to connect the charging cable for charging, the headlight can be removed from the handlebars and the charging cable connector can be inserted into the charging port 10.
[0016] Finally, it should be noted that the torsion spring 6 is made of a high-elasticity alloy material, and its preload has been optimized to ensure that the clamping force of the clamp plate 3 on the handlebars is always maintained within the range of 8-12N. When encountering bumps while riding, the torsion spring 6 can absorb more than 80% of the vertical impact force through its own deformation. At the same time, anti-slip protrusions are provided at both ends where it abuts against the lower housing 1, and the contact part between the middle and the clamp plate 3 adopts an arc-shaped fitting structure to prevent the torsion spring from shifting laterally when under force.
[0017] In addition, the fatigue life of the torsion spring 6 is no less than 100,000 compression cycles, and it can still maintain stable elastic potential energy during long-term use. Combined with the 2.5-3mm clamping gap between the arc-shaped chuck and the clamping groove 101 to adapt to common handlebar diameters, and the surface hardness of the shock-absorbing pad 7 of ≥60 ShoreA and the anti-slip texture of 0.5mm depth, it can form a dual fixing effect of 'elastic clamping + friction locking', which effectively prevents the headlight from changing angle due to relative slippage when riding bumps.
[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
