Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, and in particular to a quick-release positioning structure for embedded lighting on bicycle seatposts. Background Technology

[0002] To ensure cycling safety at night or in low-light conditions, installing lighting warning lights on bicycles has become a common choice. These lights are usually installed on the seat post or handlebars.

[0003] Currently, there are two main ways to install bicycle lights on the market. One method is to use silicone straps or rubber rings for binding and fixing. Although this method is relatively convenient for installation and removal, its connection is not very stable. During riding, especially on bumpy roads, the light is prone to displacement, angle change, or even falling off due to vibration, posing a safety hazard. The other method is to use screw clamps for fixing. Although this method improves the stability of the connection, its installation and removal process is relatively cumbersome and requires tools. This brings great inconvenience to users who need to frequently remove the light for charging or anti-theft purposes.

[0004] Most existing angle adjustment structures rely on simple friction for positioning, that is, tightening screws to press the moving joints. The positioning of this structure is unreliable. Long-term riding and bumps will gradually weaken the friction at the joints, causing the lamp angle to unconsciously nod or tilt, deviating from the optimal warning angle, thereby reducing the safety warning effect.

[0005] Therefore, this utility model proposes a quick-release positioning structure for embedded lighting on bicycle seatposts to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a quick-install positioning structure for embedded lighting in bicycle seatposts, aiming to improve the problems of cumbersome installation and disassembly, unstable connection, and inconvenient and easily changeable angle adjustment of existing bicycle lighting fixtures.

The adjustment component includes a fixed plate, a turntable, a connecting shaft, and a second spring. The fixed plate is fixedly connected to the connecting frame, and one end of the connecting shaft is fixedly connected to the lighting warning light. The outer wall of the connecting shaft is connected to the turntable via a keyway. The turntable is relatively fixedly connected to the lighting warning light via the keyway of the connecting shaft and the second spring. The connecting shaft is rotatably disposed within the fixed plate. The opposing surfaces of the fixed plate and the turntable are respectively provided with interlocking grooves and teeth. The elastic force of the second spring acts on the turntable to keep the grooves and teeth engaged and positioned under normal conditions.

[0008] Preferably, it further includes a fixing screw and a connecting ring, wherein the fixing screw passes through the connecting frame and is threaded to the L-shaped block to achieve final locking and fixing, and the connecting ring is fixedly connected to the end of the fixing screw.

[0009] Preferably, the system further includes a fixing frame, which is slidably disposed inside the connecting frame, and the first spring and the positioning pin are both accommodated within the fixing frame.

[0010] Preferably, the first spring is a compression spring, with its two ends abutting against the inner wall of the fixed frame and the positioning pin, respectively.

[0018] 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.

[0019] Reference Figures 1-9 This utility model provides an embodiment of a bicycle seatpost embedded lighting quick-release positioning structure, including a support tube 1, a seatpost 2, a bicycle seat 3, a lighting warning light 4, a quick-release assembly 5, and an adjustment assembly 6. The support tube 1 provides support for the seatpost 2, and the bicycle seat 3 is installed at the top of the seatpost 2. An insertion hole 508 is provided on the outer wall of the seatpost 2, and an L-shaped block 501 is fixedly connected thereto. The lighting warning light 4 is detachably connected to the L-shaped block 501 through the quick-release assembly 5 and the adjustment assembly 6. The quick-release assembly 5 enables quick installation and removal of the lighting warning light 4 from the seatpost 2, and the adjustment assembly 6 enables flexible adjustment of the lighting angle of the lighting warning light 4. The quick-installation component 5 includes a connecting frame 502, a fixing frame 503, a positioning pin 504, a first spring 505, a fixing screw 506, and a connecting ring 507. The connecting frame 502 is slidably sleeved on the outside of the L-shaped block 501, and the fixing frame 503 is slidably disposed inside the connecting frame 502. The first spring 505 and the positioning pin 504 are both accommodated inside the fixing frame 503. The first spring 505 is a compression spring, and its two ends abut against the inner wall of the fixing frame 503 and the positioning pin 504, respectively. Under the elastic force of the first spring 505, the positioning pin 504 passes through the connecting frame 502 and engages with the insertion hole 508 on the seat tube 2 to achieve quick initial positioning. The end of the positioning pin 504 away from the first spring 505 is formed into a conical structure, which facilitates its retraction under pressure during installation and smooth insertion into the insertion hole 508 during positioning. To achieve further locking and fixing, the L-shaped block 501 has a through hole for the fixing screw 506 to pass through. After the fixing screw 506 passes through the through hole, it is threaded to the connecting frame 502. The connecting ring 507 is fixedly connected to the end of the fixing screw 506. By tightening the connecting ring 507, the fixing screw 506 can be driven to firmly lock the connecting frame 502 onto the L-shaped block 501, ensuring the stability of the connection. An adjustment assembly 6 is located between the lighting warning light 4 and the quick-release assembly 5, in the connecting frame 502. The adjustment assembly 6 includes a fixed plate 601, a turntable 604, a connecting shaft 603, and a second spring 606. The fixed plate 601 is fixedly connected to the connecting frame 502. One end of the connecting shaft 603 is fixedly connected to the lighting warning light 4. The outer wall of the connecting shaft 603 is connected to the turntable 604 via a keyway. The turntable 604 is relatively fixedly connected to the lighting warning light 4 via the keyway of the connecting shaft 603 and the second spring 606. The fixed plate 601 and the turntable 604 have meshing grooves 602 and teeth 605 respectively formed on their opposing surfaces. The connecting shaft 603... One end is connected to the turntable 604 via a keyway to transmit torque. Meanwhile, the shaft of the connecting shaft 603 is rotatably inserted into the fixed disk 601. An axial limiting structure is provided between the connecting shaft 603 and the fixed disk 601. This structure consists of a retaining ring on the outer circumference of the connecting shaft 603 and an annular limiting groove in the fixed disk 601. This ensures that the connecting shaft 603 can only rotate freely within the fixed disk 601 without unnecessary axial displacement. The elastic force of the second spring 606 acts on the turntable 604 to continuously press the turntable 604 under normal conditions, thereby keeping the tooth groove 602 and the tooth 605 in a tight meshing and positioning state. To further improve the stability and reliability of the quick-connect assembly 5 connection, the structure also includes a fixing screw 506 and a connecting ring 507. The L-shaped block 501 has a through hole for the fixing screw 506 to pass through. The fixing screw 506 passes through the through hole and is threaded to the connecting frame 502. The connecting ring 507 is fixedly connected to the end of the fixing screw 506 away from the connecting frame 502. To make the installation and guidance of the positioning pin 504 and the first spring 505 more stable, the quick-installation assembly 5 also includes a fixing frame 503. The fixing frame 503 is slidably disposed inside the connecting frame 502. The first spring 505 and the positioning pin 504 are both accommodated in the fixing frame 503. The first spring 505 is a compression spring, and its two ends abut against the inner wall of the fixing frame 503 and the positioning pin 504, respectively. In order to facilitate the smooth sliding of the positioning pin 504 into the insertion hole 508 during installation, the end of the positioning pin 504 away from the first spring 505 is formed into a conical structure. When the connecting frame 502 slides along the L-shaped block 501, this conical structure can play a guiding role, so that the positioning pin 504 can be smoothly pressed back when it contacts the edge of the insertion hole 508, until it automatically springs in after being aligned with the hole. To ensure that the turntable 604 receives a stable and reliable reset force, the second spring 606 is a compression spring. The second spring 606 is sleeved on the outside of the connecting shaft 603, and its two ends act between the turntable 604 and the connecting base of the lighting warning light 4, respectively, ensuring the effective transmission of the spring force and continuously providing stable positive pressure for the meshing of the tooth groove 602 and the tooth 605. The material of the second spring 606 is preferably stainless steel with high fatigue strength (such as SUS304), and the spring constant of the second spring 606 is preferably in the range of 2N / mm to 10N / mm, which is intended to ensure that the locking torque generated by its preload is sufficient to resist riding bumps, while controlling the operating force required for the user to push in and unlock within an ergonomically comfortable range.

[0020] To avoid the risk of the second spring 606 twisting during rotation adjustment, a circular groove 607 is provided inside one side of the turntable 604 and the lighting warning light 4. At the same time, the two ends of the second spring 606 are fixedly connected with annular retaining rings 608 by welding or integral molding. In the assembled state, the two retaining rings 608 are respectively accommodated in the circular grooves 607 inside the turntable 604 and the lighting warning light 4, and the outer edge of the retaining rings 608 and the bottom of the circular groove 607 form a sliding connection that can rotate relative to each other, ensuring that the movement of the spring body and the rotating parts is effectively isolated.

[0021] Working principle: When the lighting warning light 4 needs to be installed, first align the connecting frame 502 connected to one side of the lighting warning light 4 with the outside of the L-shaped block 501. During the process of pushing the connecting frame 502, the fixing frame 503 inside will squeeze the positioning pin 504, so that the positioning pin 504 overcomes the elastic force of the first spring 505 and retracts inward. When the connecting frame 502 is pushed into place, the positioning pin 504 automatically pops out under the action of the first spring 505 and is inserted into the insertion hole 508 of the seat tube 2, completing the initial quick positioning. Then, by turning the connecting ring 507, the fixing screw 506 is driven through the L-shaped block 501 and screwed into the connecting frame 502, thereby firmly locking the entire device and realizing stable and reliable quick installation. When disassembling, the operation is reversed. First, loosen the connecting ring 507, and then press the positioning pin 504 to make it disengage from the insertion hole 508, so that the connecting frame 502 and the lighting warning light 4 can be removed together.

[0022] When the angle needs to be adjusted, the user presses the turntable 604 towards the side of the warning light 4. This pressing force will further compress the second spring 606, thereby forcing the turntable 604 to move axially along the keyway of the connecting shaft 603, causing the teeth 605 to disengage from the grooves 602 of the fixed plate 601. At this time, the lock is released. Simultaneously, the warning light 4 is rotated, which drives the connecting shaft 603 and the turntable 604 to rotate synchronously, thereby adjusting to a new angle. During the adjustment process, the retaining rings 608 located at both ends of the second spring 606... The second spring 606 can slide within the groove 607 in the lighting warning light 4 and the turntable 604, ensuring that it only bears axial compressive force and will not twist. When adjusted to the desired angle, the rotation is stopped and the pressing force is released. At this time, the compressed second spring 606 will release its stored elastic force, generating a thrust to push the turntable 604 back, so that the turntable 604 resets along the keyway of the connecting shaft 603. At this time, the teeth 605 of the turntable 604 re-embed into the corresponding grooves 602 of the fixed plate 601, restoring the meshing and locking state, and locking the lighting warning light 4 at the new angle.
