[0039] The upper pump body 10 is fixed to the handlebars by a locking cover structure, and the hidden oil pipe structure is integrated inside the handlebars and connected to the upper pump body 10 for supplying oil to the upper pump body 10; the handle adjustment structure is rotatably set on the upper pump body 10 and connected to the piston structure on the upper pump body 10, thereby playing a braking role.

[0040] The handle adjustment structure includes a handle fixing screw 11, a rotating bearing 12, a rotating shaft 13, and a brake handle 14.

[0041] The rotating end of the brake handle 14 is provided with a rotating bearing 12, and a handle fixing screw 11 is provided on the rotating bearing 12; the upper pump body 10 is provided with a rotating position, and the handle fixing screw 11 is connected to the rotating position, thereby realizing the rotating connection of the brake handle 14.

[0042] The brake handle 14 is rotatably mounted with a rotating shaft 13, and the rotating shaft 13 is equipped with a height adjustment screw 27, which is connected to the piston structure on the upper pump body 10, thereby realizing the installation of the brake handle 14 and the piston structure. This connection method can significantly reduce the friction when the handle is rotated, making the braking operation smoother, improving the braking response speed, and extending the service life of the handle connection part, thus reducing maintenance costs.

[0043] The concealed oil pipe structure includes an oil pipe mounting position 28, an oil pipe body 3, a clamping screw 4, a copper needle 5, and a copper sleeve 6, all located on the upper pump body 10.

[0044] The front end of the oil pipe body 3 is provided with a copper needle 5 and a copper sleeve 6, and the oil pipe body 3 is fixed to the oil pipe mounting position 28 by a clamping screw 4, and the copper needle 5 and the copper sleeve 6 are placed inside the oil pipe mounting position 28; the oil pipe mounting position 28 is connected to the oil chamber 29 of the upper pump body 10.

[0046] In order to achieve the braking effect, in this embodiment, the piston structure includes a push rod 15, a retaining ring 16, a washer 17, an O-ring 18, an upper pump piston 19, a V-ring 20, and a spring 21;

[0047] The upper pump body 10 is provided with a piston chamber, which is connected to the oil chamber 29; the push rod 15 is connected to the upper pump piston 19, and the other end of the push rod 15 is connected to the height adjustment screw 27, so that the height of the brake handle can be freely adjusted. The height adjustment screw is provided with an internal hexagon countersunk hole. By using an internal hexagon wrench to rotate the push rod, the height of the handle can be adjusted up and down; the front end of the upper pump piston 19 is provided with a spring 21, and the other end of the spring 21 contacts the piston chamber to provide the rebound power;

[0048] The push rod 15 is fitted with a retaining ring 16 and a washer 17, and the upper end of the upper pump piston 19 is provided with two sets of O-rings 18, and the lower end of the upper pump piston 19 is provided with a V-ring 20.

[0052] In addition, the oil filling hole and the exhaust hole are coaxially arranged on the top surface of the cylinder block, which facilitates simultaneous oil filling and exhaust.

[0053] In addition, the brake lever in this embodiment is designed for three-finger operation, which conforms to ergonomic principles and allows riders to brake quickly and easily during riding, making it especially suitable for models such as crawler bikes that require frequent braking.

[0054] The oil pipe of this utility model is integrated inside the handlebar (compatible with a standard handlebar tube with a diameter of 22.2mm), and both ends are connected to the pump by clamping screws and copper sleeves; the handlebar tube has a reserved inner cavity channel, and the oil pipe is not exposed throughout, avoiding physical damage and corrosion risks, as well as keeping the appearance of the vehicle clean and tidy.

[0055] Riders can use an Allen wrench to adjust the handle to a suitable height by rotating the Allen socket at the end of the push rod, according to their hand shape and operating habits.

[0056] If you notice a decrease in braking performance and suspect air in the braking system, stop the bicycle and prepare brake fluid. Loosen the bleed screw on top of the brake cylinder and slowly press the brake lever to expel air from the bleed port. After observing that there are no air bubbles in the expelled brake fluid, tighten the bleed screw while keeping the lever pressed down. Once the bleed screw is fully tightened, release the brake lever and add brake fluid to the specified level through the filler neck.

[0057] When installing the vertical cylinder hydraulic disc brake upper pump, install the main body directly in the corresponding position according to the left or right mounting requirements of the bicycle, connect the external hydraulic hose, and ensure that all connections are secure and well-sealed. After installation, check and adjust the braking performance to ensure that the braking system is working properly; the hydraulic hose enters from the middle of the handlebar, passes through the internal channel, and exits from the front end to connect to the upper pump;

[0058] Assembly process: Connect the internal wiring oil pipe → Insert the upper pump body into the pre-reserved position on the handlebar → Tighten the fixing bolts → Inject oil and bleed air test.
