Description

Technical Field

[0001] This invention relates to a bicycle operating device. Background Technology

[0002] Variable-speed bicycles are popular among consumers because their gears can be switched according to different driving conditions (flat surfaces, uphill, downhill, etc.). The controller for controlling the gears on such bicycles is fixed to a part of the bicycle (such as the handlebars) via a clamp, allowing for convenient operation near the hand. Switching the controller drives a gear cable to change the gear position.

[0003] In addition, the braking system is an extremely important safety system for bicycles, and all bicycles are equipped with at least one braking device. Brake levers are usually mounted on the handlebars for easy gripping and operation while riding.

[0004] However, in known variable-speed bicycles, the gear shifter and brake lever are two independent components, which are installed on the handlebars respectively. Therefore, the overall volume of the two components is relatively large, takes up more space, is more difficult to install, is heavier, and has higher manufacturing and purchase costs.

[0005] In another known structure, the pull lever and the release lever are located on the upper and lower sides of the transmission device, respectively, making operation difficult; in another known structure, the pull lever and the release lever are located on the same side, but the directions of movement are different, making operation prone to errors.

[0006] Therefore, it is necessary to provide a novel and progressive bicycle operating device to solve the above problems. Summary of the Invention

[0029] Please refer to Figures 1 to 6 The present invention shows a preferred embodiment of the present invention, wherein the bicycle operating device 1 of the present invention includes a housing 10, a cable winding structure 20, a brake lever 30, a first gear shift lever 40 and a second gear shift lever 50.

[0030] The housing 10 includes a coil 11 with a through hole 112. The through hole 112 has a through hole center 111 and a through hole axis 110 passing through the through hole center 111. The coil 11 is fitted onto a rod 100 (e.g., a handlebar) through the through hole 112. The cable winding structure 20 includes a spindle 21 with a first spindle axis 211. The cable winding structure 20 is rotatably disposed in the housing 10 for connecting to and driving a shift cable. The brake lever 30 is pivotally disposed in the housing 10 and is located opposite the coil 11, for connecting to and driving a brake cable. A first reference plane P1 is defined passing through the through hole center 111 and perpendicular to the first spindle axis 211. The housing 10 includes a core 111 and a second reference plane P2 that is perpendicular to the first reference plane P1 and contains the through hole axis 110. The first shift lever 40 is oscillatingly mounted on the housing 10 and has a first shift surface 41 located opposite to the lower side of the first reference plane P1. The first shift lever 40 can drive the winding structure 20 to rotate. The housing 10 also includes a second shift surface 50 that is oscillatingly mounted on the housing 10 and has a second shift surface 51 located in front of the second reference plane P2. The second shift lever 50 can drive the winding structure 20 to rotate. The second shift surface 51 is located in front of the first shift surface 41, and the operating directions of the first shift surface 41 and the second shift surface 51 are in the same direction. Therefore, the bicycle operating device 1 integrates the brake lever 30, the first gear shift lever 40, and the second gear shift lever 50, achieving braking and shifting functions without the need for multiple independent functional devices. Its integrated structure is streamlined, small in size, lightweight, low in cost, and easy to install. Furthermore, both the first gear shift lever 40 and the second gear shift lever 50 are located below the housing 10, allowing operation with just one finger (e.g., the thumb), and both operate in the same direction, making operation extremely convenient and less prone to errors. It also helps the hand grip the handlebars firmly for stable operation.

[0031] The second shifter surface 51 is located opposite to the lower side of the first reference plane P1. A third reference plane P3 is defined, which passes through the center of the through hole 111 and is perpendicular to the first reference plane P1 and the second reference plane P2. The pivot axis 521 of the pivot axis 52 of the second shift lever 50 is located on the side of the third reference plane P3 closer to the cable winding structure 20. The second shifter surface 51 passes through the third reference plane P3. The shifting direction of the first shifter surface 41 and the second shifter surface 51 is towards the front of the coil 11. The first shifter surface 41 is located below the coil 11, and the second shifter surface 51 is located below the housing 10 and between the coil 11 and the brake lever 30. The third reference plane P3 extends through the first shifter surface 41, the second shifter surface 51, and the brake lever 30, connecting to the end of the housing 10.

[0032] In this embodiment, the second shifter surface 51 is located between the first spindle axis 211 and the second reference plane P2. Preferably, the second shifter surface 51 is located within 40 mm below the first reference plane P1.

[0033] The second shifter surface 51 is closer to the first reference plane P1 than the first shifter surface 41. One of the first shifter lever 40 and the second shifter lever 50 is a cable pull lever, and the other is a cable release lever. In this embodiment, the second shifter lever 50 is a cable release lever. Specifically, the second shifter lever 50 includes a pawl portion 53. The winding structure 20 is provided with a positioning structure 22. When the second shifter lever 50 is moved, the pawl portion 53 disengages from the positioning structure 22 to perform a cable release operation. The second shifter lever 50 may be integrally formed with the pawl portion 53, or the pawl portion 53 and the second shifter lever 50 may be two cooperating (engaging or connected) components.
