Abstract
Description
A lens module Technical Field
[0001] This utility model relates to the field of lens module technology, specifically to a lens module. Background Technology
[0002] A bicycle lens is an optical element used to adjust or change the direction and distribution of light from a bicycle headlight. It is usually installed in the headlight of a bicycle and plays the role of focusing, diffusing or guiding light, thereby improving the lighting range, brightness and safety. Its structure is generally a convex lens, a concave lens or a compound lens, and the material is mostly optical-grade plastic or glass. Different beam angles and spot shapes can be designed according to lighting needs. It is widely used in cycling lighting systems for night riding, complex road environments and low light conditions.
[0003] Existing bicycle lens modules are often affected by external environmental interference during nighttime riding, especially in the high temperatures of summer. Due to the phototaxis of many flying insects, they are easily attracted to the strong light of bicycle lights. They fly at high speed near the light area and frequently collide with the lens module, resulting in a large number of insect debris remaining on the lens module surface. This seriously affects the light transmittance of the lens, leading to poor lighting performance and further affecting riding safety, especially during nighttime riding when clear lighting is required.
[0004] In view of this, we propose a lens module. Summary of the Invention

[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] Please refer to Figures 1-4. This utility model provides a technical solution: a lens module, including a lamp lens module 1, with a protective mechanism 2 on the lamp lens module 1. The protective mechanism 2 includes: a protective shell 21, which is fixedly connected to the outer wall of the lamp lens module 1; a transparent cover 22 is fixedly connected to the outer wall of the protective shell 21, and the transparent cover 22 is installed on the outer wall of the protective shell 21, allowing light to pass through smoothly while blocking external impurities from entering, thus providing protection without affecting illumination; a drive motor 23; and the inner wall of the protective shell 21. A drive motor 23 is fixedly connected to the upper part of the protective shell 21. A drive gear 24 is fixedly connected to the output shaft of the drive motor 23. A gear ring 25 is rotatably connected to the outer wall of the protective shell 21. A cleaning ring 26 is fixedly connected to the outer wall of the gear ring 25. Bristles are provided on the side of the cleaning ring 26 near the transparent cover 22. The inner side of the gear ring 25 meshes with the drive gear 24 for transmission. When the drive motor 23 is turned on, the drive gear 24 rotates, which in turn drives the gear ring 25 and the cleaning ring 26 to rotate. The bristles on the cleaning ring 26 clean the surface of the transparent cover 22. A heat dissipation mechanism 3 is provided on the upper part to dissipate heat from the lamp lens module 1. Shafts are provided on both sides of the drive gear 24, and the shafts on both sides of the drive gear 24 are rotatably connected to the protective shell 21, so that the drive gear 24 rotates stably. The output shaft of the drive motor 23 is rotatably connected to the inner wall of the protective shell 21, and a seal is provided between the protective shell 21 and the output shaft of the drive motor 23. A wire 27 is provided on the drive motor 23. One end of the wire 27 is fixedly connected to the drive motor 23, and the other end of the wire 27 is fixedly connected to the power supply 28. Connect the power supply 28 to the drive motor 23 to ensure that the drive motor 23 works normally and provides power to the relevant components so that they can perform cleaning or adjustment actions. The power supply 28 is fixedly connected to the inner wall of the protective shell 21. The power supply 28 is provided with a charging port, which allows users to directly charge the power supply system of the lens module when the power is depleted, improving the convenience and continuity of use. The protective shell 21 and the lamp lens module 1 are fixedly connected by bolts, which is convenient for disassembly and replacement. A sealing ring is provided between the protective shell 21 and the lamp lens module 1 for dust and water protection.
[0025] In this embodiment, the heat dissipation mechanism 3 includes a fan blade 31. The fan blade 31 is fixedly connected to the drive gear 24. The inner wall of the protective shell 21 is provided with an inlet channel 32, an annular connecting channel 33, a ventilation duct 34, and an outlet channel 35. The inlet channel 32, the annular connecting channel 33, the ventilation duct 34, and the outlet channel 35 are interconnected. The fan blade 31 is located on the inner wall of the outlet channel 35. The inlet channel 32 is located on the side of the lamp lens module 1. When the drive gear 24 rotates, the drive gear 24 drives the fan blade 31 to rotate. The fan blade 31 drives the air in the outlet channel 35 to be output outward, so that the air in the outlet channel 35 forms an inlet channel 35. The negative pressure creates a vacuum, allowing outside air to enter through the inlet channel 32, the annular connecting channel 33, and the ventilation duct 34 into the outlet channel 35, and then exit through the outlet channel 35. This allows the heat from the lamp lens module 1 to be carried away, thus achieving a heat dissipation effect. The airflow path formed by the inlet channel 32, the annular connecting channel 33, the ventilation duct 34, and the outlet channel 35 is a closed guiding structure, preventing air from entering the closed structure formed by the protective shell 21 and the transparent cover 22. This prevents dust or impurities from entering the lamp lens module 1 with the airflow. A filter structure is provided at the inlet channel 32 to prevent flying insects or particulate impurities from entering.
[0026] In the use of this lens module, the power supply 28 is pre-charged through the charging port. When needed, the drive motor 23 is turned on to drive the drive gear 24 to rotate. The wire 27 connects the power supply 28 to the drive motor 23 to ensure that the drive motor 23 works normally. The drive gear 24 drives the gear ring 25 and the cleaning ring 26 to rotate. The bristles on the cleaning ring 26 clean the surface of the transparent cover 22.
[0027] When the drive gear 24 rotates, it drives the fan blade 31 to rotate. The fan blade 31 drives the air in the output channel 35 to be output outward, creating a negative pressure in the output channel 35. This allows outside air to enter the output channel 35 through the inlet channel 32, the annular connecting channel 33, and the ventilation channel 34, and then be output through the output channel 35. This allows the heat of the lamp lens module 1 to be carried out, thus achieving a heat dissipation effect.
