Description

Technical Field

[0001] This utility model relates to the field of bicycle lighting technology, and in particular to a bicycle taillight. Background Technology

[0002] With increasingly busy urban traffic and rising demand for nighttime cycling, bicycle taillights are receiving more and more attention as an important safety device. However, traditional bicycle taillights mainly use point-source LED bulbs, which, limited by their beam angle, typically only provide a warning effect directly behind the rider, offering insufficient warning for vehicles approaching from the side. In actual riding, especially when turning, changing lanes, or crossing intersections, vehicles approaching from the side often fail to see the cyclist in time, and this side blind spot has become a major safety hazard for nighttime cycling. Although some products on the market have added independent LED bulbs to the sides, this solution not only increases cost and power consumption but also suffers from uneven light emission and complex installation, failing to fundamentally address the need for multi-directional warning. Utility Model Content

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0019] This utility model provides a bicycle taillight that solves the technical problem of insufficient side warning in traditional bicycle taillights.

[0020] Specifically, refer to Figure 1 , Figure 2 The bicycle taillight consists of two main parts: a housing 2 and a light panel 3.

[0021] The housing 2 is provided with a light-transmitting part 21, as shown in the reference. Figure 4 The light-transmitting portion 21 includes a first light-transmitting area 211 facing rearward, and second light-transmitting areas 212 extending forward from both ends of the first light-transmitting area 211 and facing both sides. The first light-transmitting area 211 and the second light-transmitting area 212 together form a continuous light-transmitting structure with an opening facing forward. (Refer to...) Figure 3 The lamp plate 3 is disposed inside the housing 2. The lamp plate 3 is a continuous light-emitting body. It is bent to form a shape corresponding to the light-transmitting part 21 so as to emit light to the first light-transmitting area 211 and the second light-transmitting area 212 respectively.

[0022] It should be noted that in this utility model, the directions are defined based on the normal riding state of a bicycle. Specifically, "front" refers to the direction of travel of the bicycle, that is, the direction in which the front of the bicycle is facing; "rear" refers to the direction opposite to the direction of travel of the bicycle, that is, the direction in which the rear of the bicycle is facing; "side" or "lateral" refers to the left and right sides perpendicular to the direction of travel of the bicycle. This invention is based on the normal use state of the bicycle taillight installed at the rear of the bicycle, so that the first light-transmitting area faces rearward to provide a warning for following vehicles, and the second light-transmitting area faces both sides to provide a warning for vehicles approaching from the sides.

[0023] The technical principle of this invention lies in bending the light panel 3 into a shape corresponding to the light-transmitting portion 21, allowing a single continuous light-emitting element to emit light simultaneously in the rear and side directions. When the light panel 3 is powered on, the light shines rearward through the first light-transmitting area 211, providing a warning to vehicles behind; simultaneously, the light shines to the sides through the second light-transmitting area 212, providing a warning to vehicles approaching from the sides. Because the first light-transmitting area 211 and the second light-transmitting area 212 form a continuous light-transmitting structure, a luminous warning range of more than 270 degrees can be achieved, significantly improving riding safety.

[0024] In some embodiments, refer to Figure 3 , 4 The light-transmitting part 21 is U-shaped, and correspondingly, the light panel 3 is also U-shaped. The U-shaped structure allows the taillight to maximize its light-emitting range while maintaining a compact size. The U-shaped opening faces forward, avoiding obstruction by the rider's body, ensuring that the light from the rear and sides can be effectively emitted outward.

[0025] Specifically, the light panel 3 in this case adopts a COB (Chip on Board) light panel 3. COB technology directly encapsulates multiple LED chips on a substrate to form a surface light source. Compared with traditional point light source LEDs, COB light panel 3 has advantages such as uniform light emission and good heat dissipation. During the manufacturing process, using suitable materials, the flat COB light panel 3 can be bent into a U-shape using a special mold without damage, and then fixed to the corresponding position on the bottom shell 23 by fasteners.

[0026] In some embodiments, to further optimize the side warning effect, refer to Figure 3 , 4The length of the second light-transmitting area 212 is designed to be greater than the length of the first light-transmitting area 211. Correspondingly, the first light-emitting segment on the light panel 3 corresponds to the first light-transmitting area 211, and the length of the second light-emitting segment corresponding to the second light-transmitting area 212 is also greater than the length of the first light-emitting segment, ensuring that the light panel 3 and the light-transmitting area 4 are matched in size. For example, in a specific embodiment, the length of the first light-transmitting area 211 is 30 mm, and the length of the corresponding first light-emitting segment on the light panel is also 30 mm; while the length of each second light-transmitting area 212 is 40 mm, and the length of the corresponding second light-emitting segment on the light panel is also 40 mm. To address the viewing angle requirements of vehicles approaching from the side during actual riding, the longer side light-transmitting area, combined with the corresponding length of the light-emitting segment, can provide a larger viewing angle and more sufficient light intensity, enabling vehicles approaching from the side to spot the rider earlier, effectively extending the side warning distance.

[0027] In some embodiments, refer to Figure 2 The housing 2 specifically includes a front shell 22 and a bottom shell 23, with the light-transmitting part 21 detachably disposed between the front shell 22 and the bottom shell 23. This facilitates maintenance and replacement. When it is necessary to clean or replace the light-transmitting part 21, the front shell 22 can be separated from the bottom shell 23, and the light-transmitting part 21 can be removed for processing.

[0028] In some embodiments, the bottom shell 23 is formed by a two-color injection molding process, which integrates the light-transmitting part 21 with the black bottom shell 23.

[0029] Furthermore, refer to Figure 4 The light-transmitting part 21 has multiple vertical protrusions 213 spaced apart on the side facing the lamp panel 3. These vertical protrusions 213 have a semi-circular cross-section. These vertical protrusions 213 act as optical lenses, refracting and scattering the light emitted from the lamp panel 3, resulting in a more uniform light distribution and preventing localized over-brightness or under-brightness. At the same time, the vertical protrusions 213 also increase the structural strength of the light-transmitting part 21, preventing deformation due to stress during use.

[0030] In some embodiments, regarding the internal structure, refer to Figure 2 The taillight also includes a battery 4 and a main board 5 housed within the housing 2. The light panel 3 surrounds the battery 4 and main board 5, a layout that makes full use of the internal space, resulting in a compact taillight structure. The main board 5 has control buttons 51 for controlling the brightness and on / off state of the light panel 3, allowing users to adjust the taillight brightness according to different riding environments. For example, when riding on city roads at night, it can be adjusted to medium brightness; in suburban areas or environments with low visibility, it can be adjusted to maximum brightness.

[0031] In some embodiments, for convenient charging, the motherboard 5 is also provided with a charging port 52, and the housing 2 has a corresponding opening for the charging port 52 to be exposed. In actual use, the user can directly charge the built-in battery 4 via the charging cable without removing the taillight. The charging port 52 is waterproof and, with a rubber sealing plug, ensures that water will not enter when riding in the rain.

[0032] In some embodiments, refer to Figure 1 , 2 5. The taillight is mounted via taillight bracket 1. Taillight bracket 1 has a first connecting part 11, and housing 2 has a second connecting part 24. The first connecting part 11 and the second connecting part 24 are detachably connected. Specifically, the first connecting part 11 is a slot structure, and the second connecting part 24 is a snap-fit ​​protrusion that mates with the slot structure. This quick-release structure allows users to easily remove the taillight from the bicycle, facilitating charging and maintenance, and preventing theft. During installation, simply align the snap-fit ​​protrusion with the slot and push it in; a "click" indicates proper installation. To remove, rotate the taillight in the opposite direction to disconnect and remove the taillight.

[0033] This utility model's bicycle taillight achieves a luminous warning range of over 270 degrees, not only providing a warning signal to vehicles behind but also effectively alerting vehicles approaching from the side, significantly improving safety during nighttime riding. Furthermore, its modular structure makes the product easy to assemble and maintain, meeting the needs of various riding environments.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
