[0002] An internal derailleur hub is a gearing system integrated inside the rear wheel hub of an e-bike. It achieves gear shifting through an internal mechanical structure, eliminating the need for an exposed derailleur and chain. The core of the internal derailleur hub is a planetary gear set, which changes the gear ratio through different gear combinations. When shifting gears, the internal mechanism adjusts the gear meshing method, thereby changing the gear ratio. All gear components are sealed within the hub housing, preventing external environmental interference, providing dust and water resistance, and reducing wear. The application of internal derailleur hubs in e-bikes is suitable for users who prefer urban commuting, freight transport, harsh environments, and low maintenance requirements.

[0003] Currently, there are electronically shifted internal derailleur hubs on the market, but they all come with separate battery tubes. These batteries have small capacity, limited usage times, and require frequent charging. Therefore, there is an urgent need to design a manual electronic shifting controller for internal derailleur hubs and an electric-assist bicycle to solve the above problems. Utility Model Content

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] This utility model provides, for example Figure 1-6 The manual electronic shift controller for an internal deceleration hub shown includes:

[0029] The micro motor running device 100 is fixed at one end of the inner speed hub shaft. The micro motor running device 100 includes a housing body 101, a micro motor lower cover 102 disposed at the bottom of the housing body 101, a movable conversion lever 104 disposed between the housing body 101 and the micro motor lower cover 102, and a micro motor 105 disposed on one side of the movable conversion lever 104.

[0030] The button indicator instrument device 200 is fixed on the handlebars of a bicycle. The button indicator instrument device 200 includes a button upper cover 201, a button lower cover 202, and a circuit board 203 disposed between the button upper cover 201 and the button lower cover 202. The button indicator instrument device 200 is connected to a micro motor 105 through a driver. Control commands are input through the button indicator instrument device 200. The control commands are processed by the circuit board 203 and sent to the micro motor 105. The micro motor 105 executes the control commands and performs corresponding extension and retraction movements.

[0031] One side of the button cover 201 is provided with a button 204 and an LED 205 that are electrically connected to the circuit board 203. The button 204 includes a power button, an upshift button, and a downshift button. By lightly pressing the button 204, control commands can be input to the circuit board 203 to realize the power supply of the button indicator instrument 200 and the upshift and downshift functions. The LED 205 can display the current gear of the bicycle for the rider's convenience.

[0032] For example, see Figures 2-3 As shown, the outer shell 101 and the micro motor lower cover 102 are connected by a positioning rivet 103. The movable conversion lever 104 is movably sleeved on the positioning rivet 103. One end of the movable conversion lever 104 is movably connected to the telescopic rod of the micro motor 105, and the other end is movably connected to the pin of the internal speed hub.

[0033] In this technical solution, by starting the micro motor 105, the telescopic rod of the micro motor 105 pushes one end of the movable conversion lever 104 to move around the positioning rivet 103 during the extension and retraction process. At the same time, the other end of the movable conversion lever 104 moves around the positioning rivet 103 together and pushes the pin of the internal gear hub to move, thus realizing the function of gear shifting.

[0034] For example, see Figures 2-3 As shown, a micro motor rear cover 106 is sleeved on one side of the micro motor 105, and the micro motor rear cover 106 is fixedly connected to the outer shell body 101.

[0035] In this technical solution, by setting the micro motor back cover 106, the micro motor 105 can be protected, effectively preventing damage to the micro motor 105 caused by external collisions, dust and rain. It can also limit the micro motor 105 to prevent it from detaching from the outer shell 101, thus improving the structural stability.

[0036] For example, see Figure 6 As shown, it also includes a wiring harness 300, which is a one-to-two connection control harness. One end of the wiring harness 300 is connected to the micro motor running device 100, one end is connected to the button indicator instrument device 200, and the other end is connected to the controller of the electric-assisted bicycle.

[0037] In this technical solution, the power from the electric-assisted bicycle battery is conveniently transmitted through the wiring harness 300 to the micro-motor running device 100 and the button indicator instrument device 200 via the controller, providing power support for their operation. The electric-assisted bicycle controller can directly supply power to the electronic gearbox, eliminating the need for an external battery tube and charging. This increases the number of times the electronic gear controller can be used, reduces external components, and makes the electric-assisted bicycle more aesthetically pleasing.

[0038] For example, see Figures 4-5 As shown, a mounting ring 206 is fixed to the bottom of the button cover 202, and the inner diameter of the mounting ring 206 matches the outer diameter of the bicycle handlebar.

[0039] In this technical solution, the button indicator device 200 can be easily fixed to one end of the bicycle handlebar by installing the retaining ring 206, making it convenient for the rider to operate.

[0040] For example, see Figure 6 As shown, the wiring harness 300 has three terminals, each with a different structure, and each is adapted to the wiring ports on the micro motor running device 100, the button indicator instrument device 200, and the controller of the electric-assisted bicycle, respectively.

[0041] In this technical solution, it is convenient to quickly connect the wiring harness 300 to the micro motor running device 100, the button indicator instrument device 200, and the controller of the electric-assisted bicycle, which can effectively avoid incorrect connection between the wiring terminal and the wiring port.

[0042] An electric-assisted bicycle comprising a manual electronic shifting controller with an internal derailleur hub as described above.

[0043] For example, electric-assisted bicycles are: urban commuter electric-assisted bicycles, mountain bike electric-assisted bicycles, folding portable electric-assisted bicycles, long-distance touring electric-assisted bicycles, freight electric-assisted bicycles, road sports electric-assisted bicycles, or hybrid multi-functional electric-assisted bicycles.

[0044] For example, the battery of the electric-assisted bicycle is a lithium battery or a lead-acid battery. The battery of the electric-assisted bicycle is electrically connected to the controller of the electric-assisted bicycle, so that the controller of the electric-assisted bicycle can be powered by the battery.

[0045] Working principle: Before using the manual electronic gear shifter of this internal derailleur hub, first fix the micro motor running device 100 to one end of the internal derailleur hub shaft, and fix the button indicator instrument device 200 to one end of the electric-assisted bicycle handlebars. Then, connect the micro motor running device 100, the button indicator instrument device 200 and the electric-assisted bicycle controller through the wiring harness 300. After the button indicator instrument device 200 is powered on, the gear can be switched by lightly pressing the plus and minus keys, and the extension and retraction of the micro motor 105 can be controlled to complete the manual gear shifting. The manual electronic shifter controller of this internal derailleur hub is advanced in design, compact in structure, and easy to use. By setting up a micro motor running device 100 and a button indicator device 200, the button indicator device 200 can control the operation of the micro motor running device 100, causing its internal micro motor 105 to automatically extend and retract to push the movable shift lever 104. The movable shift lever 104 then pushes the internal derailleur hub pin to realize the gear shifting function. The micro motor running device 100, the button indicator device 200, and the electric-assist bicycle controller are electrically connected together through the wiring harness 300. The electronic gear shifter can be directly powered from the electric-assist bicycle controller, eliminating the need for an external battery tube and charging. This increases the number of uses of the electronic shifter controller, reduces external components, and makes the electric-assist bicycle more aesthetically pleasing.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
