Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, and in particular to a detachable light-emitting device installed at the axle of a bicycle wheel. Background Technology

[0002] Bicycles are a popular and environmentally friendly mode of transportation. To enhance the safety and enjoyment of nighttime riding, installing lights on bicycle wheels has become a common practice. Existing bicycle wheel lights, such as the widely used hub lights, are typically designed to surround the axle of the bicycle wheel, i.e., the outer rim of the hub.

[0003] To achieve a fixed connection with the rotating shaft, traditional flower drum lamp devices often employ a "clamp"-like structure. Specifically, the main body of the device typically consists of two half-shells. One end of each half-shell is rotatably connected via a hinge or rotating shaft, while the other end is secured with bolts, screws, or other tool-operated fasteners. The main problem with this design is the cumbersome and inconvenient assembly and disassembly process: users need to use tools to tighten or loosen the bolts to complete the installation or removal.

[0004] When the device needs charging, battery replacement, or internal light-emitting components repair, the user must perform a complete disassembly, making quick separation of the main body impossible. More importantly, because the two halves are hinged at the connecting end and bolted at the other, the internal light-emitting components (such as LED strips) typically need to be designed as a continuous strip, running through the hinge point and extending to cover both halves, to maintain circuit continuity and operational consistency. This continuous strip design means that even when the two halves are separated at the hinge, the strip remains physically connected, preventing physical separation of the light-emitting components and further limiting the device's flexibility in assembly, disassembly, and maintenance.

[0005] Therefore, existing bicycle wheel lighting devices generally suffer from inconvenient assembly and disassembly, resulting in a poor user experience. Users urgently need a wheel lighting device that can be quickly assembled and disassembled without tools, while also facilitating maintenance of the lighting components and power supply.

[0053] Example

[0054] This embodiment aims to address the common problem of inconvenient installation and removal, resulting in a poor user experience, in existing bicycle wheel lighting devices. Therefore, referring to... Figure 1-5 As shown, this embodiment provides a bicycle wheel light-emitting device that can be quickly disassembled and is easy to charge and maintain. The user experience is improved by the split semi-ring structure and the synchronously separated light-emitting components 300.

[0055] Reference Figure 1-3 As shown, a bicycle wheel light-emitting device includes an annular body 100, an elastic abutment component 200, a light-emitting component 300, and a power supply 400.

[0056] The annular body 100 is made of transparent or semi-transparent material; wherein, the annular body 100 includes a first semi-annular structure 101 and a second semi-annular structure 102, the first semi-annular structure 101 and the second semi-annular structure 102 are detachably connected so that the first semi-annular structure 101 and the second semi-annular structure 102 form a complete annular body 100 when they are combined, and the inner ring of the annular body 100 is fastened to the axle of the wheel.

[0057] The inner rings of the first semi-ring structure 101 and the second semi-ring structure 102 are respectively provided with elastic abutment components 200. The elastic abutment components 200 are used to clamp the wheel axle. It can be understood that the elastic abutment components 200 are provided on the inner side wall of the annular body 100 to firmly abut the annular body 100 against the wheel axle, so as to prevent the annular body 100 from slipping or shifting during the rotation of the wheel.

[0058] The light-emitting component 300 is disposed within the annular body 100 and is used to emit light to the outer periphery of the annular body 100. It can be understood that the light-emitting component 300 is evenly distributed on the inner wall of the annular body 100 to provide a uniform and eye-catching light-emitting effect.

[0059] Reference Figure 1 and 3 As shown, the power supply 400 is located inside the annular body 100 and is electrically connected to the light-emitting component 300; the power supply 400 supplies power to the light-emitting component 300 to ensure its normal operation.

[0060] Reference Figure 1-3 As shown, the light-emitting component 300 includes a first light-emitting structure 301 and a second light-emitting structure 302. The first light-emitting structure 301 is disposed within a first semi-ring structure 101, and the second light-emitting structure 302 is disposed within a second semi-ring structure 102. When the first semi-ring structure 101 and the second semi-ring structure 102 are combined, the first light-emitting structure 301 and the second light-emitting structure 302 are electrically connected. It can be understood that the first semi-ring structure 101 and the second semi-ring structure 102, as well as the first light-emitting structure 301 and the second light-emitting structure 302, can be synchronously separated, thereby simplifying the charging and maintenance process and greatly improving the user experience.

[0061] Furthermore, to ensure the stability and safety of the light-emitting component 300, the first light-emitting structure 301 and the second light-emitting structure 302 are electrically connected using an elastic abutment method, ensuring that the light-emitting component 300 will not disconnect due to vibration or external force during wheel rotation. In addition, the power supply 400 uses a high-efficiency lithium battery to ensure long-term battery life.

[0062] Reference Figure 4As shown, it should be added that the end face of the first semi-ring structure 101 is provided with a positioning protrusion 110, and the end face of the second semi-ring structure 102 is provided with a positioning groove 111. The positioning protrusion 110 and the positioning groove 111 are precisely matched to ensure that the first semi-ring structure 101 and the second semi-ring structure 102 are quickly and firmly connected, further improving the stability of the overall structure and the ease of installation.

[0063] Reference Figure 4 and 5 As shown, in some embodiments, the first light-emitting structure 301 includes a first contact member 303 extending out of the first semi-ring structure 101; the second light-emitting structure 302 includes a second contact member 304 extending out of the second semi-ring structure 102; when the first semi-ring structure 101 and the second semi-ring structure 102 are combined, the first contact member 303 and the second contact member 304 come into contact with each other, thereby establishing an electrical connection, so that the first light-emitting structure 301 and the second light-emitting structure 302 can emit light together. For example, the first connector 303 uses a terminal block with a flat surface for each terminal. A first window 103a adapted to the terminal block is provided at the end face of the first semi-ring structure 101, allowing each terminal to protrude from the first window 103a. The second connector 304 uses a pin terminal block adapted to the terminal block, comprising multiple resilient pins 305. A second window 103b is provided on the second semi-ring structure 102 for the pin terminal block to extend. Each pin corresponds to a terminal of the terminal block, ensuring tight contact, effective current conduction, and improved connection stability. When the two semi-ring structures separate, the pin terminal block automatically springs back, disconnecting the electrical connection and ensuring safety.

[0064] Reference Figure 1-3 As shown, in some embodiments, the first light-emitting structure 301 further includes a first light strip 301a. The inner wall of the first semi-ring structure 101 is provided with a first arc-shaped groove 306 adapted to the first light strip 301a. The first light strip 301a is disposed in the first arc-shaped groove 306 so that the multiple lamp beads 301b of the first light strip 301a can be distributed divergently along the first arc-shaped groove 306. The first electrical connector 303 is disposed at the end of the first light strip 301a and is detachably connected to the inner wall of the first semi-ring structure 101. The second light-emitting structure 302 also includes a second light strip 302a. The inner wall of the second semi-ring structure 102 is provided with a second arc-shaped groove 307 that is adapted to the second light strip 302a. The second light strip 302a is disposed in the second arc-shaped groove 307, so that the multiple lamp beads 301b of the second light strip 302a can be distributed divergently along the second arc-shaped groove 307. The second electrical connector 304 is disposed at the end of the second light strip 302a and is detachably connected to the inner wall of the second semi-ring structure 102.

[0065] Furthermore, the design of the first arc-shaped groove 306 and the second arc-shaped groove 307 not only provides a stable mounting position for the light strip but also ensures that the LED beads 301b can be evenly distributed circumferentially, enhancing the luminous effect. The LED beads 301b are distributed divergently along the arc-shaped grooves, making the light emitted by the bicycle wheels more uniform and brighter when riding at night, improving the rider's visibility and enhancing safety. It should be added that there are evenly distributed locking protrusions 308 on one side of the inner wall of the first arc-shaped groove 306 and the second arc-shaped groove 307. The locking protrusions 308 move and abut against one side of the LED beads 301b, and a small gap is formed between the locking protrusions 308 and the opposite side wall of the first arc-shaped groove 306 or the second arc-shaped groove 307. This gap matches the thickness of the light strip, ensuring that the light strip is firmly installed without affecting the luminous effect. For example, multiple locking protrusions 308 within the first arc-shaped groove 306, and the lamp beads 301b located at one end of the lamp strip within the first arc-shaped groove 306, have their right sides abutting against the adjacent locking protrusions 308, with each lamp bead 301b corresponding to one locking protrusion 308. Meanwhile, the lamp beads 301b located at the other end of the lamp strip have their left sides abutting against the adjacent locking protrusions 308, forming a stable fixing structure to ensure that the lamp strip does not shift during high-speed rotation and maintains a constant light emission angle.

[0066] Reference Figure 1 and 3 As shown, in some embodiments, the inner wall of the first semi-ring structure 101 and / or the second semi-ring structure 102 is provided with at least one toothed portion 309, and the at least one toothed portion 309 corresponds to the lamp bead 301b of the light-emitting component 300. For example, the inner wall of the first arc-shaped groove 306 and / or the second arc-shaped groove 307 opposite to the lamp cover is provided with a toothed portion 309. The toothed portion 309 is partially configured to form an inner arc-shaped tooth, and the middle part of the lamp bead 301b corresponds to the outwardly recessed intersection of the toothed portion 309, so that the light from the lamp bead 301b can be uniformly scattered from the inner arc-shaped tooth of the toothed portion 309, forming a more dazzling light effect. The special design of the toothed portion 309 not only enhances the light scattering effect but also avoids the glare problem caused by direct light, improving visual comfort. Through this refined optical layout, the wheel light-emitting device not only provides sufficient illumination during nighttime riding but also creates a unique visual effect, enhancing the riding experience.

[0067] Reference Figure 1 , 3 As shown in Figure 5, in some embodiments, the light-emitting component 300 includes a main control circuit board 501, a control button 505, and a charging port 506.

[0068] The main control circuit board 501 is disposed within the annular body 100 and electrically connected to the first light-emitting structure 301 or the second light-emitting structure 302. The main control circuit board 501 is equipped with a main control chip 503. Control buttons 505 are disposed on the main control circuit board 501, and the annular body 100 is provided with button slots 107, with one end of the control buttons 505 extending out of the button slots 107. A charging port 506 is connected to the main control circuit board 501, and the annular body 100 is provided with a charging slot 108, with one end of the charging port 506 extending into the charging slot 108. The main control chip 503 is used to control the lighting mode of the first light-emitting structure 301 and / or the second light-emitting structure 302, and the control buttons 505 are used to adjust the lighting mode. It can be understood that the main control circuit board 501 is located within the annular body 100 and electrically connected to the first light-emitting structure 301 and / or the second light-emitting structure 302. The integrated main control chip 503, i.e., the MCU, is used for programming and controlling the lighting mode and responding to commands. The annular body 100 has a plug-in slot 502, which facilitates the insertion and engagement of the main control circuit board 501. Control buttons 505 are located on the main control circuit board 501, with the physical button portion extending out of the button slot 107 of the annular body 100. Their functions include: adjusting the lighting mode by triggering different signals, such as long press to turn on or off; and short press to trigger different signals to adjust the lighting mode, such as color switching, brightness adjustment, or dynamic effects. The charging port is electrically connected to the main control circuit board 501, with its interface extending into the charging slot 108 of the annular body 100. It supports external power supply 400 to power the internal battery or the light-emitting component 300. The collaborative logic is as follows: when the user operates the control button 505, an electrical signal is generated to the main control chip 503. The main control chip 503 parses the instruction and drives the light-emitting component 300 to switch lighting modes.

[0069] Exemplary application scenario: Short press of control button 505: Switch preset modes (e.g., white light → warm light → RGB cycle); Long press of button: Power on and off. The main control chip 503 controls the LED driver circuit through PWM signals to achieve color gradient. When the charging port, such as USB-C, is connected to the power supply 400, the charging management IC is automatically activated, and the charging indicator light 504 located inside the ring-shaped body 100 is illuminated.

[0070] It should be added that the button slot 107 uses a silicone sealing ring for waterproofing, and the charging slot 108 has a built-in dust cover 108a to improve durability.

[0071] Reference Figure 3As shown, in some embodiments, a pressure sensor is disposed inside the annular body 100. The pressure sensor is electrically connected to the main control chip 503. The pressure sensor is used to detect the centrifugal force of rotation and can adjust the flashing frequency of the LED beads 301b according to the bicycle's speed. When the bicycle speed increases, the centrifugal force increases, the pressure sensor senses this change and transmits the signal to the main control chip 503. The main control chip 503 dynamically adjusts the flashing frequency of the LED beads 301b according to a preset algorithm, so that the light-emitting device can display different visual effects according to the change of bicycle speed. This enhances the fun and safety of riding, and also makes the bicycle more eye-catching at night or in low-light environments, improving the rider's visibility.

[0072] Reference Figure 1-3 As shown, in some embodiments, the annular body 100 includes at least two first snap-fit ​​structures 601. The at least two first snap-fit ​​structures 601 are disposed within the first semi-annular structure 101, and each of the at least two first snap-fit ​​structures 601 includes a hook portion 601a extending from the end face of the first semi-annular structure 101; exemplaryly, the at least two first snap-fit ​​structures 601 are symmetrically disposed within the first semi-annular structure 101. The end face extending from the hook portion 601a is the end face that contacts the second semi-annular structure 102.

[0073] The second semi-ring structure 102 is provided with a buckle slot 603 that is adapted to the hook part 601a. ​​The hook part 601a can be inserted into the buckle slot 603 and hooked onto the inner port of the buckle slot 603.

[0074] Reference Figure 1-3 As shown, the annular body 100 further includes a first elastic element 602, which is disposed within the first semi-annular structure 101, with one end abutting against the inner wall of the first semi-annular structure 101 and the other end abutting against at least two first snap-fit ​​structures 601. It should be added that the first snap-fit ​​structure 601 is provided with a pin post 601c, and the first elastic element 602 is inserted into the pin post 601c to form a stable elastic support, ensuring that the snap-fit ​​structure is tightly connected.

[0075] At least two first snap-fit ​​structures 601 are slidably disposed inside the first semi-ring structure 101. Each of the at least two first snap-fit ​​structures 601 is provided with a release part 601b. The first semi-ring structure 101 is provided with at least two release slots 109. The release part 601b extends outward from the first semi-ring structure 101 along the at least two release slots 109. The snap-fit ​​principle is that the snap-fit ​​structure provides a rebound force through an elastic element to ensure a tight connection. During release,

[0076] By manually pressing the release part 601b, the release part 601b moves along the release slot 109 and pushes the first snap-fit ​​structure 601 to slide inside the first semi-ring structure 101, causing the hook part 601a to disengage from the inner port of the snap-fit ​​slot 603. The entire hook part 601a can then detach axially from the snap-fit ​​slot 603, thereby achieving the disassembly of the annular body 100. This facilitates quick installation and removal of the wheel light-emitting component 300 by the user. For example, the first elastic element 602 is a spring, one end of which is connected to the inner wall of the first semi-ring structure 101, and the other end is connected to the pins 601c of at least two first snap-fit ​​structures 601, providing elastic force for the first snap-fit ​​structure 601 to move vertically towards the snap-fit ​​slot 603, ensuring stable engagement between the hook part 601a and the snap-fit ​​slot 603.

[0077] Reference Figure 1 and 3 As shown, in some embodiments, the elastic abutment assembly 200 includes a connecting cylinder 201 and a second elastic member 202.

[0078] One end of the connecting cylinder 201 is provided with an arc-shaped abutment portion 201a; one end of the second elastic member 202 is disposed inside the other end of the connecting cylinder 201; the inner rings of the first semi-ring structure 101 and the second semi-ring structure 102 are respectively provided with sliding grooves 104, and are positioned opposite to each other; the other end of the second elastic member 202 abuts against the inside of the sliding groove 104; the other end of the connecting cylinder 201 can move along the sliding groove 104;

[0079] The connecting cylinder 201 has a limiting protrusion 201b on its outer side and a limiting groove 104a on its side wall that is adapted to the limiting protrusion 201b. When the connecting cylinder 201 is at the end of its stroke, the limiting protrusion 201b abuts against the limiting groove 104a, limiting the connecting cylinder 201 to slide out.

[0080] When the connecting cylinder 201 is subjected to external force, it can be buffered by the elastic force of the second elastic element 202 to avoid damage caused by rigid impact. The second elastic element 202, such as a spring, provides elastic force for the connecting cylinder 201 to move towards the end of the sliding groove 104, while the arc-shaped abutment portion 201a can fit tightly against the wheel axle, enhancing the connection between the light-emitting component 300 and the wheel.

[0081] When the light-emitting component 300 needs to be installed on the wheel, the user can align the arc-shaped abutment part 201a of the connecting cylinder 201 with the wheel axle and apply force to push the connecting cylinder 201, so that the connecting cylinder 201 moves inward along the sliding groove 104 until the first half-ring structure 101 and the second half-ring structure 102 are snapped together to form a complete ring body 100, thus completing the installation.

[0082] Reference Figure 1-3 As shown, in some embodiments, the first semi-ring structure 101 includes a housing body 105 and a housing cover 106. The housing body 105 has a first mounting slot for accommodating the power supply 400; the housing cover 106 is adapted to the housing body 105 and is detachably connected to the housing body 105 by fasteners, and the power supply 400 is clamped between the housing cover 106 and the housing body 105. The second semi-ring structure 102 similarly adopts the structure of the housing body 105 and the housing cover 106, which also facilitates the installation of the connecting cylinder 201 and the second elastic member 202 into the sliding groove 104.

[0083] The beneficial effects of the bicycle wheel light-emitting device in this embodiment are mainly reflected in the following aspects: First, the split semi-ring structure and synchronously separated light-emitting components 300 design enable quick assembly and disassembly of the light-emitting device, facilitating charging and maintenance for users and improving user experience. Second, the light-emitting components 300 are evenly distributed on the inner wall of the annular body 100, providing a uniform and eye-catching light-emitting effect, enhancing the rider's visibility and improving safety during nighttime riding. Furthermore, the design of the elastic abutment component 200 ensures that the annular body 100 can be firmly abutted against the wheel axle, preventing slippage or displacement during wheel rotation and guaranteeing the stability and reliability of the light-emitting device. In addition, the light-emitting components 300 form an electrical connection through elastic abutment, ensuring that the light-emitting components 300 will not disconnect due to vibration or external force during wheel rotation, further improving the stability and safety of the light-emitting device. Simultaneously, the design of the first arc-shaped groove 306 and the second arc-shaped groove 307 not only provides a stable installation position for the light strip but also ensures that the LED beads 301b are evenly distributed around the circumference, enhancing the light-emitting effect and creating a unique visual effect. In addition, the main control circuit board 501 integrates a main control chip 503 for programming control of the lighting mode and response commands. Users can adjust the lighting mode, such as color switching, brightness adjustment, or dynamic effects, through the control button 505, increasing the fun and personalization of riding. Finally, the pressure sensor inside the ring body 100 can adjust the flashing frequency of the LED beads 301b according to the bicycle's speed, allowing the lighting device to display different visual effects according to changes in speed, further enhancing the fun and safety of riding.
