Description

Technical Field

[0001] This utility model relates to the field of motorcycle brake pump technology, specifically a brake pump for motorcycles. Background Technology

[0002] The motorcycle brake pump is the core hydraulic component that enables the motorcycle to brake. It converts the mechanical force applied by the rider to the brake lever (or pedal) into hydraulic energy, which drives the brake pads (or brake shoes) to rub against the brake disc (or brake drum), thereby achieving deceleration or stopping. The mounting structure of the brake lever is an indispensable part of its overall structure.

[0003] For example, a motorcycle brake pump and brake mounting structure with announcement number "CN214524265U" features a hinged integrated clamp structure, which is less prone to losing parts and uses a single bolt for easy installation. After installation, a spring compression mechanism applies pressure to the clamp and bolt, preventing loosening and stripping of the bolt, ensuring stable installation. A washer is fitted to the outer end of the first bolt to increase the tightness of the lock. The inner surfaces of the mounting base and clamp are covered with a rubber layer to increase friction when fixed to the handlebars. However, this structure has limitations. When the handlebars to be fixed are thin, the inner side of the clamp cannot fit tightly against the handlebars, easily causing displacement (i.e., too loose and prone to displacement). When the handlebars are thick, the clamp cannot close properly, and the bolt cannot pass through the clamp for fixation (i.e., too tight and unable to close), thus reducing its versatility in use. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when the handlebars to be fixed are thin, the inner side of the clamp cannot fit tightly with the handlebars, which easily causes displacement; when the handlebars are thick, the inner side of the clamp can fit tightly with the handlebars, but the bolts cannot pass through the clamps for fixing, thus reducing the versatility of use. Therefore, this invention proposes a brake pump for motorcycles.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a brake pump for motorcycles, including a brake pump body. The left side of the brake pump body is provided with an installation structure, which includes a fixing block. The outer wall of the fixing block is fixedly connected to the brake pump body. Guide posts are fixedly connected to the four corners on the left side of the fixing block. The outer walls of the guide posts are slidably connected to a slider. Multiple arc-shaped blocks are fixedly connected to the inner sides of the slider and the fixing block.

[0007] Preferably, the outer wall of each arc-shaped block is fixedly connected with a rubber pad.

[0008] Preferably, the inner walls of both the slider and the fixing block are threadedly connected to bolts.

[0009] Preferably, a handle is installed on the rear side of the brake pump body.

[0010] Preferably, a cover plate is installed on the top of the brake pump body.

[0011] The present invention provides a brake pump for motorcycles, which has the following advantages: By cooperating with the main body of the brake pump and the mounting structure, multiple arc-shaped blocks are placed on both sides of the motorcycle handlebars. Then, the operator places the slider on multiple guide posts, and then makes the outer wall of the rubber pad fit against the motorcycle handlebars. Afterwards, multiple bolts are manually rotated so that the bolts are screwed into the slider and the fixing block in sequence, so that the multiple arc-shaped blocks can be centered and the position of the slider can be adjusted to expand or shrink the closed space. This can reduce the situation where the clamp is too loose and causes displacement, or too tight and causes failure to close, when fixed by clamp. To a certain extent, it can improve the versatility of use. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-6In this embodiment, a brake pump for a motorcycle includes a brake pump body 1. The left side of the brake pump body 1 is provided with an installation structure 3. The installation structure 3 includes a fixing block 301. The outer wall of the fixing block 301 is fixedly connected to the brake pump body 1. Guide posts 303 are fixedly connected to the four corners on the left side of the fixing block 301. The guide posts 303 can play a guiding role. The outer walls of the guide posts 303 are slidably connected to the slider 302. Multiple arc-shaped blocks 304 are fixedly connected to the inner sides of the slider 302 and the fixing block 301.

[0021] Rubber pads 305 are fixedly connected to the outer wall of the arc-shaped block 304. The rubber pads 305 can increase the friction. The inner walls of the slider 302 and the fixed block 301 are threaded with bolts. A handle 2 is installed on the rear side of the brake pump body 1, and a cover plate 4 is installed on the top of the brake pump body 1.

[0022] Working principle:

[0023] When using a motorcycle brake pump structure:

[0024] The operator first places multiple arc-shaped blocks 304 on both sides of the motorcycle handlebars. Then, the operator places the slider 302 onto multiple guide posts 303, and then ensures that the outer wall of the rubber pad 305 is in contact with the motorcycle handlebars. Afterward, the operator manually rotates multiple bolts, causing the bolts to be screwed into the slider 302 and the fixing block 301 in sequence. At this time, the outer wall of the rubber pad 305 is pressed against the motorcycle handlebars, which can play a role in preventing slippage. The multiple arc-shaped blocks 304 can be centered, and the position of the slider 302 can be adjusted to expand or shrink the closed space. This can reduce the situation where the clamp is too loose, causing displacement, or too tight, causing failure to close, when fixed by clamp. To a certain extent, it can improve the versatility of use.

[0025] When braking is needed, the rider squeezes handle 2, which rotates around a fixed point. Through the lever principle, the force is amplified, pushing the push rod (not shown in the figure) forward (inward to the brake pump body 1). The push rod pushes the piston inside the brake pump body 1 to compress the return spring and move forward. The sealing ring at the front end of the piston seals the inner cavity of the brake pump body 1, cutting off the connection between the reservoir (i.e., the upper part of the brake pump body 1) and the brake pump body 1. The piston continues to squeeze the brake fluid inside the brake pump body 1. Since the liquid is incompressible, the pressure inside the cavity rises rapidly, causing the high-pressure brake fluid to enter the brake line through the outlet and be transmitted to the front brake caliper along the line. The piston inside the caliper is hydraulically pushed, causing the brake pads to move closer to the brake disc and clamp, thus slowing down the wheel.

[0026] When braking is no longer needed, the rider releases handle 2, which returns to its original position under the action of its own return spring. The push rod no longer applies pressure, and the return spring inside the brake pump body 1 pushes the piston to move backward (outside the brake pump body 1). The volume of the inner cavity of the brake pump body 1 increases, the pressure decreases, the sealing ring at the rear end of the piston leaves the closed position, and the reservoir and brake pump body 1 are reconnected. Brake fluid flows from the reservoir into the brake pump body 1 to replenish the cavity space and prepare for the next braking. At the same time, the brake pads inside the caliper disengage from the brake disc under the action of their own reset structure (such as the elasticity of the dust cover or the return spring), and the brake is released.

[0027] When brake fluid needs to be added, open cover 4, add the fluid, and then reinstall cover 4.
