Technical Field

[0001] This utility model relates to the field of bicycle technology, specifically to a brake lever with a parking mechanism. Background Technology

[0002] The bicycle brake lever is a key component that riders manually operate to brake. When the brake lever is gripped, the internal mechanical or hydraulic mechanism transmits force to the brake caliper or brake pad, pushing the brake pads or brake disc to press against the wheel or disc, generating friction to slow down or stop the bicycle.

[0003] However, existing technologies still have the following problems:

[0004] Most existing bicycle brake levers are not convenient for quick and easy parking. When cyclists park on a slope, traditional brake levers either require continuous force to maintain the braking state, which is very tiring for cyclists, or if the grip is loosened even slightly, the vehicle may slip, posing a safety hazard.

[0005] To address the aforementioned problems, the inventors proposed a brake lever with a parking mechanism to solve them. Summary of the Invention

[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] Example: Figure 1-4As shown, this utility model provides a brake lever with a parking mechanism, including a support box 1. A bracket 2 is fixedly mounted on one side of the support box 1. The support box 1 is made of high-strength aluminum alloy and is formed by precision die casting, which has good strength and corrosion resistance, and can effectively protect the internal structure. The bracket 2 is fixedly mounted on one side by welding to ensure a stable connection. A brake lever 21 is rotatably mounted inside the bracket 2. A limiting disc 26 is fixedly mounted on the outer surface of the brake lever 21. A disc groove 28 is opened inside the bracket 2. The outer surface of the limiting disc 26 is movably fitted with the disc groove 28. A through-type annularly distributed limiting groove 27 is opened on the upper surface of the limiting disc 26. A limiting block 32 is fixedly mounted on one side of the bracket 2, and a positioning pin 3 is movably inserted into the upper surface of the limiting block 32. The lower end of the positioning pin 3 passes through one of the limiting grooves 27. After the rider grips the brake lever 21, he applies force along the rotation axis of the bracket 2 to rotate the brake lever 21. The brake cable mounting block 22 on the brake lever 21 moves accordingly, pulling... The brake cable transmits the tension of the brake lever 21 to the braking device at the wheel, causing the braking device to clamp the wheel and generate friction, thus slowing down or stopping the bicycle. During the rotation of the brake lever 21, the limiting disc 26 on its outer surface rotates synchronously within the disc groove 28 of the bracket 2. The cooperation between the limiting disc 26 and the disc groove 28 ensures the stability and accuracy of the rotation of the brake lever 21, preventing the brake lever 21 from shaking or deviating during rotation. When the brake lever 21 is rotated to a position that allows the bicycle to brake stably, a parking operation is performed. The positioning pin 3 is inserted from the upper surface of the limiting block 32. The lower end of the positioning pin 3 passes through one of the limiting grooves 27 on the limiting disc 26, and the convex disc 31 at the upper end of the positioning pin 3 engages with the slot 34 at the upper end of the placement tube 33. At the same time, the positioning pin 3 moves within the circular groove 35. This structure allows the positioning pin 3 to effectively limit the rotation of the limiting disc 26, thereby fixing the position of the brake lever 21. Even if the rider releases the brake lever 21, the braking system remains in a braking state, achieving parking.

[0020] A limiting pin 23 is provided through the upper surface of the bracket 2, and the outer surface of the limiting pin 23 is movably connected to the brake lever 21. The lower end of the limiting pin 23 passes through the bracket 2 and is fixedly provided with a stud 24. A nut 25 is threaded onto the outer surface of the stud 24, and the nut 25 is movably fitted with the lower surface of the bracket 2. The limiting pin 23 passes through the bracket 2 and is movably connected to the brake lever 21. The stud 24 at its lower end cooperates with the nut 25. By adjusting the position of the nut 25 on the stud 24, the constraint force of the limiting pin 23 on the brake lever 21 can be changed, ensuring the stability of the rotation shaft of the brake lever 21 and preventing the brake lever 21 from abnormally displacing or shaking due to force during braking and parking.

[0021] An upper clamp 11 is fixedly provided on one side of the support box 1, and a lower clamp 12 is connected to the lower surface of the upper clamp 11 by bolts. An inlet slot 13 is provided on one side of the support box 1, and an outlet slot 14 is provided on the other side of the support box 1. The outlet slot 14 and the inlet slot 13 are connected. A brake cable mounting block 22 is fixedly provided on one side of the brake lever 21. A cover plate 15 is connected to the upper surface of the support box 1 by bolts, and an installation slot 16 is provided on one side of the support box 1. The support box 1 is connected by bolts through the upper clamp 11 and the lower clamp 12, which can securely install the brake lever on the bicycle handlebars. The inlet slot 13 and the outlet slot 14 of the support box 1 provide through channels for components such as brake cables, ensuring the rationality and smoothness of the brake cable connection. The cover plate 15 on the upper surface of the support box 1 is connected by bolts, which makes it easy to open for inspection and maintenance of internal components. The installation slot 16 can be used to install other auxiliary equipment or to facilitate maintenance operations.

[0022] The upper end of the positioning pin 3 is fixedly provided with a convex plate 31. The diameter of the convex plate 31 is larger than that of the positioning pin 3, and the surface is covered with rubber material to increase friction and facilitate the rider's operation of inserting and removing the positioning pin 3. The upper surface of the bracket 2 is fixedly provided with a placement tube 33, and the upper end of the placement tube 33 is provided with a slot 34 for use with the positioning pin 3 and the convex plate 31. The upper surface of the bracket 2 is provided with a circular groove 35 for use with the positioning pin 3. When parking is not required, the positioning pin 3 is placed in the placement tube 33. At this time, the convex plate 31 is locked in the slot 34, and the positioning pin 3 is locked in the circular groove 35, so that the positioning pin 3 structure can be properly placed when parking is not required.

[0023] Working principle: After the rider grips the brake lever 21, he applies force to rotate the brake lever 21 along the rotation axis of the bracket 2. The brake cable mounting block 22 on the brake lever 21 moves accordingly, pulling the brake cable. The brake cable transmits the tension of the brake lever 21 to the braking device at the wheel, causing the braking device to clamp the wheel and generate friction, thereby slowing down or stopping the bicycle. During the rotation of the brake lever 21, the limiting disc 26 on its outer surface rotates synchronously in the disc groove 28 of the bracket 2. The cooperation between the limiting disc 26 and the disc groove 28 ensures the stability and accuracy of the rotation of the brake lever 21, preventing the brake lever 21 from shaking or deviating during the rotation.

[0024] When the brake lever 21 is rotated to a position that allows the bicycle to brake stably, the parking operation is performed. The positioning pin 3 is inserted from the upper surface of the limiting block 32. The lower end of the positioning pin 3 passes through one of the limiting grooves 27 on the limiting plate 26. The convex plate 31 at the upper end of the positioning pin 3 is engaged in the slot 34 at the upper end of the placement tube 33. At the same time, the positioning pin 3 moves in the circular groove 35. This structure allows the positioning pin 3 to effectively limit the rotation of the limiting plate 26, thereby fixing the position of the brake lever 21. Even if the rider releases the brake lever 21, the braking system remains in a braking state, thus achieving parking.

[0025] The limiting pin 23 passes through the bracket 2 and is movably connected to the brake lever 21. The stud 24 at its lower end cooperates with the nut 25. By adjusting the position of the nut 25 on the stud 24, the constraint force of the limiting pin 23 on the brake lever 21 can be changed, ensuring the stability of the rotating shaft of the brake lever 21 and preventing the brake lever 21 from undergoing abnormal displacement or shaking due to force during braking and parking.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
