Description

Technical Field

[0001] This utility model relates to the field of bicycle disc brake technology, specifically an anti-lock bicycle disc brake. Background Technology

[0002] Bicycle disc brakes are a type of braking system that achieves braking by clamping a metal disc (rotor) fixed to the wheel. They are characterized by strong braking force, good heat dissipation, and long service life, and are widely used in mountain bikes and high-performance bicycles. Disc brakes consist of a brake disc (rotor) and a brake caliper. When braking, hydraulic or mechanical transmission causes the brake pads to clamp the rotor, generating friction to achieve braking.

[0003] Currently, the most commonly used brakes on bicycles are disc brakes. However, disc brakes often lock up in the summer, often making it impossible to press the brake pedal, causing difficulty in turning the tires, and in more serious cases, directly leading to brake failure. Moreover, replacing brake pads later is very difficult. Therefore, an anti-lock disc brake for bicycles is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an anti-lock bicycle disc brake to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-lock bicycle disc brake, comprising a brake disc;

[0006] The oil tank is located on the left side of the brake disc;

[0007] The brake caliper is located between the oil tank and the brake disc, with the brake disc inside the brake caliper and a cavity inside the brake caliper.

[0008] And a door hinged to the top of the fuel tank, wherein a brake assembly is provided inside the brake caliper;

[0009] An anti-lock-up component is provided between the oil tank and the brake caliper.

[0010] Preferably, the brake assembly includes a connecting block located inside the brake caliper. A locking block and an adjusting rod are provided inside the cavity. Two locking blocks and two adjusting rods are symmetrically arranged. The bottom end face of the adjusting rod is fixedly connected to the top end face of the locking block. The top end face of the adjusting rod slides through the inner wall of the cavity and extends to the top of the brake caliper. A slot adapted to the locking block is formed through the top end face of the connecting block. The bottom end face of the locking block slides through the inner wall of the cavity and the top end face of the connecting block and extends into the slot. A spring is sleeved on the surface of the adjusting rod. The upper and lower end faces of the spring are fixedly connected to the inner wall of the cavity and the top end face of the locking block, respectively.

[0011] Preferably, the anti-lock assembly includes a hydraulic hose located between the oil tank and the brake caliper. The left end face of the hydraulic hose is fixedly inserted through the right side of the oil tank and extends into the interior of the oil tank. The right end face of the hydraulic hose is fixedly inserted through the left side of the brake caliper and extends into the cavity. A filter screen is fixedly connected to the right end face of the hydraulic hose. The filter screen can filter large particles of debris and discharge the filtered large particles of debris through a discharge pipe.

[0012] Preferably, a pull plate is provided above the adjusting rod, and the bottom surface of the pull plate is fixedly connected to the top surface of the adjusting rod. The pull plate facilitates the movement of the adjusting rod, thereby adjusting the position of the locking block.

[0013] Preferably, two support plates are fixedly connected to the right side of the connecting block, and the two support plates are located above and below the brake disc, respectively.

[0014] Preferably, a fixing block and a friction plate are provided between the brake disc and the two support plates. The inner wall of the support plate is connected to the inner wall of the fixing block and the friction plate respectively by bolts. The bolts facilitate the connection with the friction plate, and the fixing block provides support for the friction plate.

[0015] Preferably, a drain pipe is provided above the hydraulic oil pipe. The bottom right end of the drain pipe is fixedly inserted through the surface of the hydraulic oil pipe and extends into the interior of the hydraulic oil pipe. A valve is provided inside the drain pipe. The drain pipe can vent and drain oil to prevent the hydraulic oil from expanding due to heat or seizing due to excessive gas.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This anti-lock bicycle disc brake uses a brake assembly to pull a lever to drive an adjustment rod, causing the locking block to disengage from the slot of the connecting block. Combined with the spring's reset function, this allows for quick disassembly of the connecting block. During disassembly, only the bolts securing the friction pads need to be removed, without disassembling the entire brake caliper. This simplifies the traditionally cumbersome brake pad replacement process, improves maintenance efficiency, and addresses the pain point of "extremely difficult brake pad replacement" in the background technology.

[0018] This anti-lock bicycle disc brake utilizes an anti-lock component that adds a filter screen to the end of the hydraulic oil line to effectively intercept large particulate contaminants in the oil, preventing brake lock-up caused by impurities clogging the oil circuit from the source. A drain pipe with a valve is installed above the hydraulic oil line to periodically discharge filtered impurities, excess hydraulic oil that has expanded due to heat, or mixed gas, completely solving the lock-up failure caused by oil expansion and air resistance, and significantly improving braking reliability in high-temperature environments.

Detailed Implementation

[0026] 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.

[0027] Example 1: Please refer to Figure 1 - Figure 4 and Figure 6 This utility model provides a technical solution: an anti-lock bicycle disc brake, including a brake disc 1;

[0028] Oil tank 3 is located to the left of brake disc 1;

[0029] The brake caliper 2 is located between the oil tank 3 and the brake disc 1. The brake disc 1 is located inside the brake caliper 2, and the brake caliper 2 has a cavity inside.

[0030] And a door 5 hinged to the top of the fuel tank 3, and a brake assembly 40 is provided inside the brake caliper 2;

[0031] An anti-lock component 41 is provided between the oil tank 3 and the brake caliper 2.

[0032] Brake assembly 40 includes a connecting block 401 located inside the brake caliper 2. A locking block 405 and an adjusting rod 406 are disposed inside the cavity. Two locking blocks 405 and two adjusting rods 406 are symmetrically arranged. The bottom end of the adjusting rod 406 is fixedly connected to the top end of the locking block 405. The top end of the adjusting rod 406 slides through the inner wall of the cavity and extends above the brake caliper 2. The top surface of the connecting block 401 has a through-hole groove adapted to the locking block 405. The bottom end of the locking block 405 slides through the inner wall of the cavity and the top surface of the connecting block 401 and extends into the groove. A spring 407 is sleeved on the surface of the adjusting rod 406. The upper and lower ends of the spring 407 are respectively connected to the inner wall of the cavity and the locking block 405. Block 405 is fixedly connected to the top surface. Through the brake assembly 40, the adjusting rod 406 is driven by pulling the pull plate 408, causing the locking block 405 to disengage from the slot of the connecting block 401. With the reset function of the spring 407, the connecting block 401 can be quickly disassembled. During disassembly, only the bolts fixing the friction pad 404 need to be removed without disassembling the entire brake caliper. This simplifies the traditionally cumbersome brake pad replacement process, improves maintenance efficiency, and solves the pain point of "very difficult brake pad replacement in the later stage" in the background technology. The double locking blocks 405 symmetrically lock the connecting block 401, ensuring the structural stability of the brake assembly 40 during the braking process and avoiding safety accidents caused by single-point failure.

[0033] A pull plate 408 is provided above the adjusting rod 406, and the bottom surface of the pull plate 408 is fixedly connected to the top surface of the adjusting rod 406.

[0034] Two support plates 402 are fixedly connected to the right side of the connecting block 401. The two support plates 402 are located above and below the brake disc 1, respectively.

[0035] A fixing block 403 and a friction plate 404 are provided between the brake disc 1 and the two support plates 402. The inner wall of the support plate 402 is bolted to the inner wall of the fixing block 403 and the inner wall of the friction plate 404 respectively.

[0036] Example 2: Based on Example 1, a preferred embodiment of the anti-lock bicycle disc brake provided by this utility model is as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5As shown: The anti-lock component 41 includes a hydraulic oil pipe 411 located between the oil tank 3 and the brake caliper 2. The left end of the hydraulic oil pipe 411 is fixedly inserted through the right side of the oil tank 3 and extends into the interior of the oil tank 3. The right end of the hydraulic oil pipe 411 is fixedly inserted through the left side of the brake caliper 2 and extends into the cavity. A filter screen 412 is fixedly connected to the right end of the hydraulic oil pipe 411. By adding a filter screen 412 at the end of the hydraulic oil pipe 411, the anti-lock component 41 effectively intercepts large particulate contaminants in the oil, preventing brake lock-up caused by impurities clogging the oil circuit from the source. A drain pipe 413 with a valve is installed above the hydraulic oil pipe 411, which can periodically discharge filtered impurities, excessive hydraulic oil that has expanded due to heat, or mixed gas, completely solving the lock-up failure caused by oil expansion and gas resistance, and significantly improving the braking reliability in high-temperature environments.

[0037] A drain pipe 413 is installed above the hydraulic oil pipe 411. The bottom right end of the drain pipe 413 is fixedly inserted through the surface of the hydraulic oil pipe 411 and extends into the hydraulic oil pipe 411. A valve is installed inside the drain pipe 413. The combination of filter screen 412 and drain pipe 413 actively eliminates hidden dangers in the hydraulic system and reduces the risk of sudden lock-up.

[0038] During use, when the device is working, open the door 5 and add hydraulic oil to the tank 3. With the brake applied, the hydraulic oil enters the cavity through the hydraulic oil pipe 411 and the filter screen 412. The filter screen 412 filters out large particles of impurities in the hydraulic oil. Open the valve, and the filtered large particles of impurities are directly discharged through the discharge pipe 413. This effectively prevents impurities in the hydraulic oil from clogging the filter screen 412 and causing seizure. At the same time, in summer when the temperature is too high, air and oil can be discharged to prevent the hydraulic oil from expanding due to heat or seizure caused by excessive gas, thereby reducing the occurrence of bicycle seizure and lowering the risk of accidents.

[0039] When replacing the friction pad 404, pull the pull plate 408. The pull plate 408 moves the adjusting rod 406, causing the locking block 405 to slide out of the slot and squeeze the spring 407. This causes the connecting block 401 to move from the inside of the brake caliper 2. Then, remove the bolts and remove the friction pad 4 from the fixing block 403. Replace the new friction pad 4 with a bolt and connect the friction pad 4. Then, put the connecting block 401 into the brake caliper 2, release the pull plate 408, and the spring 407 will push the locking block 405 into the slot, thus installing the connecting block 401 inside the brake caliper 2, thereby replacing the friction pad 404.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
