Description

Technical Field

[0001] This utility model relates to the field of bicycle modification lighting technology, specifically a multifunctional bicycle modification light. Background Technology

[0002] A bicycle retrofit light is a portable lighting device that is typically mounted on the handlebars, seat, frame, or wheel hub of a bicycle using a clamping structure. It is used to provide illumination and safety warnings for nighttime riding or in low-light environments.

[0003] Existing bicycle clip-on lights are typically tightly connected to the bicycle frame using methods such as clips, threaded locking, or elastic clamps. While they provide stable fixation and illumination under normal riding conditions, bicycles are prone to tipping over or falling when encountering uneven surfaces or unexpected situations. When the entire bicycle tips over and impacts the ground, the clip-on light, as a protruding component, often makes contact with the ground first. Due to the tight connection between the light body and the frame, and the lack of a buffer structure or release design, the impact force is directly transmitted between the light body and the connection point, easily causing the clip-on light body to crack, deform, or damage internal electronic components. It may also cause scratches or stress concentration damage to the surface of the bicycle body. From the force transmission path analysis, it can be seen that the rigid connection structure cannot effectively disperse stress under external impact, resulting in localized rigid resistance and causing localized structural damage.

[0004] In view of this, we propose a multi-functional bicycle modification light. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional bicycle modification light, which solves the problem that existing bicycle clip lights are rigidly connected to the bicycle body, and are easily damaged by the direct transmission of impact force when the vehicle falls.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multifunctional bicycle modification light includes a housing and a lampshade. The housing has a light-emitting mechanism for illumination and a protective mechanism comprising: a rotating shell hinged to the housing; a spiral spring between the rotating shell and the housing, one end of which is fixedly connected to the rotating shell, and the other end of which is fixedly connected to the housing; a fixing buckle on the housing; a movable buckle on the rotating shell; and a ring-shaped airbag sleeve fixedly connected to the inner wall of the housing. The housing also includes a release mechanism for automatically releasing the connection between the housing and the bicycle body in the event of a severe collision.

[0008] Preferably, the lamp mechanism includes a rechargeable battery, which is fixedly connected to the inner wall of the housing. A control circuit board, an LED bulb, a regular switch, a flashing switch, and a charging port are fixedly connected to the housing. The regular switch and the flashing switch are both connected to the control circuit board. The control circuit board is connected to the rechargeable battery via wires, and the control circuit board is connected to the LED bulb via wires. A charging PCB board is provided on the rechargeable battery, and the charging PCB board is connected to the charging port.

[0009] Preferably, the releasing mechanism includes an elastic rope, one end of which is fixedly connected to the inner wall of the outer shell, and the other end of which is fixedly connected to a fixing buckle. A spring is provided on the inner wall of the fixing buckle, one end of which is fixedly connected to the inner wall of the fixing buckle, and the other end of which is fixedly connected to a positioning block. The positioning block is slidably connected to the inner wall of the fixing buckle. An L-shaped tube is fixedly connected to the inner wall of the annular airbag sleeve. A spring is provided on the inner wall of the L-shaped tube, one end of which is fixedly connected to the inner wall of the L-shaped tube, and the other end of which is fixedly connected to a long rod. The outer wall of the long rod is piston-connected to the L-shaped tube. The fixing buckle is obliquely slidably connected to the inner wall of the outer shell.

[0010] Preferably, the control circuit board is equipped with a voltage regulator chip, and the screen flashing switch has multiple modes of control.

[0011] Preferably, the outer casing is provided with a dustproof and waterproof sealing ring, and the control circuit board integrates a low voltage protection module.

[0012] Preferably, the outer casing and the lampshade are detachable, and the outer casing is provided with heat dissipation holes.

[0013] Preferably, the elastic rope is made of multi-strand fiber rope core covered with a rubber layer, and both the ordinary switch and the screen flash switch are provided with waterproof sleeves.

[0014] By employing the above technical solution, this utility model provides a multifunctional bicycle modification light. It possesses at least the following beneficial effects:

[0015] 1. This utility model, by setting up a protective mechanism, has a ring-shaped airbag sleeve with elasticity and buffering function in the clamping part. When the vehicle falls or collides, the airbag sleeve can buffer and absorb the impact force, prevent the impact force from being directly transmitted to the lamp body and connecting parts, effectively prevent damage to the lamp cover and shell, and improve the impact resistance and durability of the entire lamp assembly.

[0016] 2. By setting a release mechanism, this utility model can automatically release the rigid locking connection between the rotating shell and the outer shell when encountering a violent collision, so that the lamp clamp can be quickly separated under high impact. This avoids the impact force being directly transmitted to the lamp body through the clamping structure, reduces the risk of structural damage and circuit failure, and improves the safety and service life of the entire lamp.

[0025] 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.

[0026] Please see Figure 1 - Figure 6As shown, this utility model provides a technical solution: a multi-functional bicycle modification light, including a housing 1 and a lampshade 2. A lamp mechanism 3 is provided on the housing 1 for illumination. A protective mechanism 4 is provided on the housing 1, comprising: a rotating shell 41 hinged to the housing 1; a spiral spring between the rotating shell 41 and the housing 1, one end of which is fixedly connected to the rotating shell 41, and the other end of which is fixedly connected to the housing 1; a fixing buckle 42 on the housing 1; and a movable buckle 43 on the rotating shell 41. The fixing buckle 42 and the movable buckle 43 cooperate to lock the rotating shell 41. A ring-shaped airbag sleeve 44 is fixedly connected to the inner wall of the rotating shell 41 and the housing 1. When the user unfolds the rotating shell 41, it connects to the housing 1 through the hinge structure. The movable buckle 43 and the fixing buckle 42 on the rotating shell 41 and the housing 1 respectively cooperate to lock the rotating shell 41 through a mechanical locking mechanism. When the bicycle is in the closed state, the spiral spring is in a charged state. At this time, the rotating shell 41 and the outer shell 1 form a closed clamping structure, which can clamp and fix the handlebars, stem, and other parts of the bicycle. The inner side of the clamping part is provided with a ring-shaped airbag sleeve 44. The airbag sleeve has elasticity and cushioning function. When clamping, it can fit against the outer surface of the rod, which not only enhances the stability of the clamping, but also plays a role in anti-slip and cushioning impact, thereby avoiding direct contact with the outer shell 1 and causing wear or scratches. It remains stable and does not loosen during riding. At the same time, when the bicycle falls or collides, the ring-shaped airbag sleeve 44 provides cushioning protection, preventing damage to the outer shell 1 and the lamp cover 2 due to rigid contact. It effectively improves the durability and safety of the product, extends its service life, and has multiple functions such as anti-slip, shock absorption, and protection of the bicycle body. It is a structural design that integrates fixation and protection. The outer shell 1 is provided with a release mechanism 5, which is used to automatically release the connection between the outer shell 1 and the bicycle body when the bicycle suffers a violent collision.

[0027] The lighting mechanism 3 includes a rechargeable battery 31, which is fixedly connected to the inner wall of the outer casing 1. A control circuit board 32, an LED bulb 33, a standard switch 34, a flashing switch 35, and a charging port 36 are fixedly connected to the upper part of the outer casing 1. The standard switch 34 and the flashing switch 35 are both connected to the control circuit board 32. The control circuit board 32 is connected to the rechargeable battery 31 via wires, and to the LED bulb 33 via wires. A charging PCB board is mounted on the rechargeable battery 31 and connected to the charging port 36. The rechargeable battery 31 is fixedly installed inside the outer casing 1 to provide power to the entire lighting mechanism 3. The control circuit board 32 serves as the core control unit and is connected to the charging port 36 via wires. The rechargeable battery 31 is connected to the LED bulb 33. The ordinary switch 34 and the flashing switch 35 are both connected to the control circuit board 32, which is used for the user to manually control the bulb's on / off state and switch the lighting mode. The rechargeable battery 31 has a charging PCB board, which is connected to the charging port 36, so that the external power source can charge the battery through the charging port 36, thereby achieving cyclic use. The LED bulb 33 lights up after receiving the instruction from the control circuit board 32, providing lighting effect. Different modes such as constant light or flashing can be switched through the dual switch control, improving visibility and warning during riding, effectively enhancing riding safety. It also has a rechargeable function through the charging port 36, which has the advantages of multiple functions and is suitable for long-term outdoor use scenarios.

[0028] The release mechanism 5 includes an elastic rope 51, one end of which is fixedly connected to the inner wall of the outer shell 1, and the other end of which is fixedly connected to a fixing buckle 42. A spring 53 is provided on the inner wall of the fixing buckle 42, one end of which is fixedly connected to the inner wall of the fixing buckle 42, and the other end of which is fixedly connected to a positioning block 54. The positioning block 54 is slidably connected to the inner wall of the fixing buckle 42. An L-shaped tube 52 is fixedly connected to the inner wall of the annular airbag sleeve 44, and a spring 56 is provided on the inner wall of the L-shaped tube 52. One end of spring 56 is fixedly connected to the inner wall of L-shaped tube 52, and the other end of spring 56 is fixedly connected to a long rod 55. The outer wall of the long rod 55 is connected to the piston of L-shaped tube 52. The fixing buckle 42 is obliquely slidably connected to the inner wall of the outer shell 1. Under normal conditions, spring 53 pushes the positioning block 54 to extend, so that it engages with the inner wall of the outer shell 1, thereby securing the fixing buckle 42 inside the outer shell 1, keeping the entire clamping structure locked and reliably clamped to the bicycle frame. When the bicycle suffers a severe impact, the ring-shaped airbag sleeve 4... 4. Under external pressure, the internal gas generates high pressure and is conducted to the L-shaped tube 52, causing the spring 56 inside the L-shaped tube 52 to compress, driving the long rod 55 to extend. The long rod 55 presses against the positioning block 54, pushing it into the fixing buckle 42 and releasing its snap-fit ​​relationship with the outer shell 1. Since the fixing buckle 42 is a slanted sliding connection, under the action of the rebound force of the spiral spring, the rotating shell 41 automatically opens, and at the same time, it drives the fixing buckle 42 to slide away from the outer shell 1. During this process, the elastic rope 51 is stretched to maintain a flexible connection with the bicycle body and prevent the clamp lamp from falling off completely and being lost. When the bicycle is involved in a violent collision, this structure can automatically release the rigid lock between the clamp lamp and the bicycle body, avoiding the impact force from being directly transmitted to the lamp body through the fixed structure, thereby effectively preventing problems such as lamp shell breakage and control circuit damage. At the same time, the airbag and elastic structure are used to achieve buffering and shock absorption and delayed release, so that it has the ability to be firmly locked in the normal state and can be quickly released in extreme situations, ensuring the safety of the clamp lamp and the bicycle body, and improving the product's impact resistance, service life and practical safety performance.

[0029] The control circuit board 32 is equipped with a voltage regulator chip to stabilize the LED output voltage. The flashing switch 35 has multiple control modes, including constant light, slow flashing, and fast flashing. The housing 1 is equipped with a dustproof and waterproof sealing ring to improve the overall sealing performance. The control circuit board 32 integrates a low voltage protection module, which automatically turns off the LED bulb 33 when the voltage is lower than the set value. The housing 1 and the lampshade 2 are detachable for easy removal and replacement of the lampshade 2. The housing 1 is equipped with heat dissipation holes to accelerate the dissipation of internal heat and improve the working stability of the lamp mechanism 3. The elastic rope 51 is made of multi-strand fiber rope core covered with a rubber layer, which combines strength and elasticity. Both the ordinary switch 34 and the flashing switch 35 are equipped with waterproof sleeves, which are suitable for harsh outdoor environments.

[0030] In use, this multifunctional bicycle modification light allows the user to unfold the rotating shell 41, which connects to the outer shell 1 via a hinge structure. Movable latches 43 and fixed latches 42, respectively provided on the rotating shell 41 and the outer shell 1, cooperate to lock the rotating shell 41 in a closed state via a mechanical locking mechanism. At this time, the spiral spring is in a charged state, and the rotating shell 41 and the outer shell 1 form a closed clamping structure, which can clamp and fix the bicycle handlebars, stem, and other parts. An annular airbag sleeve 44 is provided on the inner side of the clamping part; this airbag sleeve is elastic. With its cushioning function, it conforms to the outer surface of the rod during clamping, enhancing clamping stability and providing anti-slip and impact cushioning. This prevents the outer shell 1 from directly contacting and causing wear or scratches, maintaining stability and preventing loosening during riding. In the event of a fall or collision, the ring-shaped airbag sleeve 44 provides cushioning protection, preventing damage to the outer shell 1 and the lampshade 2 due to rigid contact. This effectively improves the product's durability and safety, extends its service life, and has multiple functions such as anti-slip, shock absorption, and protection of the bicycle frame. It is a structural design that integrates fixation and protection.

[0031] Under normal conditions, spring 53 pushes the positioning block 54 out, causing it to engage with the inner wall of the outer shell 1, thereby securing the fixing buckle 42 inside the outer shell 1. This keeps the entire clamping structure locked and reliably clamped to the bicycle frame. When the bicycle experiences a severe impact, the annular airbag sleeve 44 is subjected to external compression, generating high pressure in the internal gas, which is then conducted to the L-shaped tube 52. This causes spring 56 inside the L-shaped tube 52 to compress, pulling the long rod 55 out. The long rod 55 presses against the positioning block 54, pushing it into the fixing buckle 42 and releasing its engagement with the outer shell 1. Since the fixing buckle 42 is a slanted sliding connection, under the rebound force of the spiral spring, the rotating shell 41... When the device is activated, the fixing buckle 42 is simultaneously pulled away from the outer casing 1 along the slide. During this process, the elastic rope 51 is stretched to maintain a flexible connection with the vehicle body, preventing the lamp from falling off completely and being lost. In the event of a severe collision with the bicycle, this structure can automatically release the rigid lock between the lamp and the vehicle body, preventing the impact force from being directly transmitted to the lamp body through the fixing structure. This effectively prevents problems such as lamp shell breakage and control circuit damage. At the same time, the airbag and elastic structure are used to achieve buffering and shock absorption and delayed release, so that it can not only be firmly locked in the normal state, but also quickly loosen and release in extreme situations, ensuring the safety of the lamp and the vehicle body, and improving the product's impact resistance, service life and practical safety performance.
