[0037] The present application will be further described below in combination with the accompanying drawings. Figures 1-3 The present application will be further described below in combination with the accompanying drawings.

[0038] The present application discloses an inner-wiring vertical cylinder oil brake mechanism and a bicycle. Referring to Figure 1 , the inner-wiring vertical cylinder oil brake mechanism includes a handlebar 1 and an oil brake mechanism 2.

[0039] Referring to Figure 2 , the oil brake mechanism 2 includes an oil brake shell 21, an oil tank 22 arranged in the oil brake shell 21, and an oil pipe 23 directly connected with the oil tank 22. The handlebar 1 is provided with a perforation 11 for the oil pipe 23 to communicate, and the oil brake shell 21 covers the perforation 11. Through this design, the oil pipe 23 extends along the inside of the handlebar 1 through the perforation 11, reducing the exposure of the oil pipe 23, improving the aesthetics of the head part, and protecting the oil pipe 23 from external damage, improving the safety and comfort of riding. At the same time, the oil pipe 23 and the oil tank 22 are directly connected, greatly reducing the risk of oil leakage caused by other joints, and improving the safety of the brake structure.

[0040] ​Specifically, in one specific embodiment, the oil brake shell 21 includes a main shell 211 and a secondary shell 212. The main shell 211 covers the oil tank 22, and the secondary shell 212 covers the oil pipe 23 and the perforation 11. The secondary shell 212 is detachably connected to the main shell 211. The main shell 211 and the secondary shell 212 can be made of metal materials, such as aluminum alloy or stainless steel, to enhance structural strength and corrosion resistance. The secondary shell 212 can be made of plastic materials, such as ABS or polycarbonate, to reduce weight and cost. The connection between the main shell 211 and the secondary shell 212 can be achieved by screws, buckles or adhesives to ensure the firmness and sealing of the connection. The thickness of the main shell 211 is generally between 2mm and 4mm, and the surface can be anodized to increase wear resistance and aesthetics. The main shell 211 can be provided with reinforcing ribs to improve structural rigidity and vibration resistance.

[0041] The oil tank 22 is arranged in a circular arc shape near one side of the handlebar 1 and is arranged in an inclined manner away from the handlebar 1. This design can optimize the internal space layout of the oil tank 22, better adapt to the space inside the shell, reduce the shaking of the oil during driving, and improve the stability and reliability of the brake system. The material of the oil tank 22 can be selected as aluminum or copper alloy to ensure good heat dissipation performance and corrosion resistance. The capacity of the oil tank 22 can be adjusted according to actual needs, generally between 100ml and 200ml.

[0042] Referring to Figure 3 , the connection between the oil pipe 23 and the oil tank 22 is provided with a sealing structure 24 to prevent oil leakage. The sealing structure 24 can include a single-layer sealing ring or a multi-layer sealing ring, such as a double-layer sealing ring 241, to form a double sealing. The sealing ring can be made of rubber or silicone material to ensure good sealing performance and durability. The oil pipe 23 can be made of high molecular materials, such as polyurethane or nylon, to improve flexibility and pressure resistance. The diameter of the oil pipe 23 can be selected according to actual needs, generally between 4mm and 6mm.

[0043] Referring to Figure 2 , the oil brake shell 21 is arranged in an inclined manner away from one side of the handlebar 1, which is in line with the brake. This design not only makes the appearance of the whole vehicle more coordinated and beautiful, but also reduces wind resistance and improves riding efficiency. In addition, by designing the oil brake shell 21 to be inclined on one side, the oil pipe 23 can be completely wrapped inside the oil brake shell 21, reducing the possibility of oil pipe 23 being exposed, and facilitating the maintenance of the oil brake mechanism 2 when the oil brake shell 21 is detached.

[0044] In another specific embodiment, the oil brake shell 21 adopts an integrated molding design covering the oil tank 22 and the oil pipe 23. The oil brake shell 21 adopts a high-strength aluminum alloy material with a thickness generally between 2mm and 4mm, and the surface is treated by anodic oxidation to increase wear resistance and aesthetics. The oil brake shell 21 is internally provided with reinforcing ribs to improve structural rigidity and anti-vibration performance. The oil brake shell 21 is provided with an access hole, which can be circular or rectangular, and the size can be adjusted according to actual needs. The access hole can be arranged at the top or side of the oil brake shell 21 for easy operation. The cover of the access hole can be of magnetic type or screw type to ensure sealing and convenience.

[0045] By adopting the integrated molding design of the oil brake shell 21, the strength and sealing performance of the overall structure are improved, the assembly process is simplified, and the production efficiency is improved. The internal reinforcing rib design of the oil brake shell 21 increases the structural rigidity and anti-vibration performance, improves the stability and reliability of the brake system. The design of the access hole facilitates daily maintenance and improves the user experience. The direct connection design of the oil pipe 23 and the oil tank 22 reduces the risk of oil leakage and improves the safety of the brake structure. The overall design makes the appearance of the whole vehicle more coordinated and beautiful, reduces wind resistance, and improves riding efficiency.

[0046] The implementation principle of the inner-wiring vertical cylinder oil brake mechanism according to an embodiment of the present application is that the oil pipe 23 extends along the inside of the handlebar 1 through the perforation 11, reducing the exposure of the oil pipe 23, improving the aesthetics of the vehicle head part, and protecting the oil pipe 23 from external damage, improving the safety and comfort of riding. At the same time, the direct connection between the oil pipe 23 and the oil tank 22 greatly reduces the risk of oil leakage caused by other connectors, improving the safety of the brake structure.

[0047] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
