Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically a bicycle taillight. Background Technology

[0002] During bicycle riding, especially at night or in poor lighting conditions, taillights are necessary to warn oncoming vehicles and pedestrians to avoid collisions. Existing bicycle taillights suffer from problems such as insecure installation, inconvenient installation and removal, and their warning effectiveness being greatly affected by environmental conditions, making it difficult to meet the actual safety and ease-of-use requirements of cycling.

[0003] Therefore, it is essential to design a bicycle taillight that is securely installed, easy to install and remove, and has a good warning effect. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a bicycle taillight that solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bicycle taillight, including a mounting mechanism and a lamp assembly, which, through a reasonable structural design, achieves stable installation, convenient assembly and disassembly, and efficient warning function, as detailed below:

[0008] Installation organization:

[0009] Mounting base: Serving as the basic mounting carrier, the rear end features an arc-shaped mounting surface that conforms to the curved structure of the bicycle frame, facilitating a snug fit. The anti-slip strips at both ends of the arc-shaped mounting surface are made of rubber with 3mm-spaced horizontal anti-slip textures, increasing friction with the bicycle mounting area and preventing the taillight from loosening during riding vibrations. The bolt mounting hole in the center of the lower part of the arc-shaped mounting surface is for inserting bolts. A groove connects with the bolt mounting hole, facilitating bolt operation and accommodating the bolt head, thus fixing the mounting base to the bicycle frame. The slot at the front of the top of the mounting base is used for sliding engagement with the light assembly's locking block, achieving initial assembly positioning. Two symmetrically arranged reinforcing ribs on the inner wall of the groove, with a rectangular cross-section, 3mm thick and 6mm high, enhance the structural strength of the mounting base and prevent deformation during installation and riding.

[0010] Through holes: These are located at both ends of the slot and mate with the threaded holes at both ends of the card block. They are used to install the limit screws of the quick-release assembly.

[0011] Lighting components:

[0012] The locking block slides into the slot, with threaded holes at both ends corresponding to the through holes in the slot. It is equipped with limit screws to enable quick assembly and disassembly from the mounting base, facilitating the replacement of lighting components, charging, and other operations.

[0013] Portable Lighting Fixture: Utilizes LED light source and a built-in rechargeable battery. A charging port is located at the rear for convenient charging and extended battery life. The LED light source has a rated voltage of 3.7V and a rated power of 0.8W, resulting in low energy consumption and sufficient brightness for warning purposes. The warning light at the center of the rear is a flashing LED light with a flashing frequency of 2Hz, enhancing the visibility of the warning. The light sensors on the upper and lower sides of the center of the rear can detect light intensity. When the light intensity is below 15 Lux in a dimly lit environment, the portable lighting fixture and warning light will automatically turn on, eliminating the need for manual operation and providing timely warnings.

[0014] Reflectors: Located on both sides of the rear end of portable lights, made of acrylic material with a mirror-polished surface and a reflectivity of no less than 88%, they can reflect incident light along its original direction, utilizing the light from vehicles behind to enhance the nighttime warning effect and assist LED light sources in improving overall warning performance.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the rear end of the mounting base is curved to fit the mounting surface of the bicycle frame. It is equipped with anti-slip strips (rubber material + 3mm spacing horizontal anti-slip texture) to greatly improve the friction with the frame. Combined with the fixing structure of bolt mounting holes and grooves, as well as the reinforcing ribs (rectangular cross section, 3mm thick and 6mm high) in the grooves to strengthen the mounting base, the taillight is not easy to loosen or shift due to riding vibration after installation, ensuring long-term stable use.

[0017] 2. In this utility model, the lamp assembly slides and engages with the mounting base through a locking block and a quick-release component (limiting screw + through hole + threaded hole), allowing for quick disassembly and assembly without complicated tools. This facilitates charging, maintenance, or replacement of the lamp assembly, solves the problem of cumbersome disassembly and assembly of traditional taillights, and improves the convenience of daily use.

[0018] 3. In this utility model, the light intensity is detected in real time by a photosensitive sensor. When the light intensity is lower than 15 Lux, the portable LED light fixture (3.7V, 0.8W) and the flashing warning light (2Hz frequency) are automatically turned on without manual operation. This is precisely adapted to the needs of riding in dim environments. The reflector (acrylic material, reflectivity ≥88%) can reflect the light from behind. Together with the actively emitting light fixture, it enhances the nighttime warning effect from the "active + passive" dimension and reduces the risk of rear-end collisions and other accidents.
