Technical Field
[0001] This utility model belongs to the field of bicycle parts technology, specifically relating to an automatic electronic shifting controller for an internal derailleur hub and a bicycle. Background Technology
[0002] An internal derailleur hub is a shifting system integrated inside the rear wheel hub of a bicycle. It achieves gear changes 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 shifting components are sealed within the hub housing, preventing external environmental interference, providing dust and water resistance, and reducing wear.
[0003] Currently, there are internally derailleur hubs with electronic shifting available on the market. However, each shift requires the rider to manually press different buttons, which is cumbersome and makes it difficult to shift to the correct gear at the right time, resulting in less than smooth shifting. Therefore, there is an urgent need to design an automatic electronic shifting controller for internally derailleur hubs and a bicycle to solve these problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic electronic speed control for an internal speed-changing hub, comprising:
[0006] A micro motor running device is fixed at one end of the inner speed hub shaft. The micro motor running device includes a housing body, a micro motor lower cover disposed at the bottom of the housing body, a movable conversion lever disposed between the housing body and the micro motor lower cover, and a micro motor disposed on one side of the movable conversion lever.
[0007] A button indicator instrument device is fixed on the handlebars of a bicycle.

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.
[0029] 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.
[0030] This utility model provides, for example Figure 1-7 The automatic electronic shift controller for an internal deceleration hub shown includes:
[0031] 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.
[0032] A 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 electrically connected to a micro motor 105 through a driver. The button indicator instrument device 200 can transmit control commands to the micro motor 105. The micro motor 105 executes the control commands and performs corresponding extension and retraction movements. When the micro motor 105 extends and retracts, it drives the position of one end of the movable conversion lever 104 to change. The other end of the movable conversion lever 104 drives the pin (also called the shift push rod) of the internal gear hub to realize the hub shifting.
[0033] The speed measuring device 300 includes a Hall sensor and a magnet. The Hall sensor is fixed to the front fork of the bicycle, and the magnet is fixed to the spokes of the wheel hub, with both at the same distance from the axle. The speed measuring device 300 is electrically connected to the button-indicator instrument 200. When the bicycle wheel rotates, the magnet moves closer to the Hall sensor once for each revolution, at which point the sensor outputs a pulse voltage. By counting these pulse signals using a counter, the rotational speed of the wheel can be calculated, and thus the riding speed can be determined. The speed measuring device 300 transmits the riding speed as an electrical signal to the button-indicator instrument 200. When the riding speed reaches 10-12 km / h, the hub shifts gears and up a gear. When the riding speed reaches 16-18 km / h, the circuit board 203 receives a signal and outputs a command, and the hub shifts gears again. This allows the hub to automatically shift gears according to the change in riding speed, making the shifting process smoother and avoiding the need for the rider to frequently operate the button indicator device 200, thus improving riding comfort. It should be noted that the speed measuring device 300 can also use a reflective photoelectric sensor or a wireless sensor, as long as it can measure the wheel speed of the bicycle through a matching technical solution.
[0034] The power supply device 400 is fixed on the bicycle frame (specifically, on the top tube, bottom tube, or stem of the bicycle frame). The power supply device 400 is electrically connected to the micro motor running device 100, the button indicator instrument device 200, and the speed measuring device 300.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] For example, see Figures 4-5 As shown, a button 204 and an LED 205 electrically connected to the circuit board 203 are provided on one side of the button cover 201. The button 204 includes an automatic shift button, an upshift button, and a downshift button.
[0040] In this technical solution, by lightly pressing the automatic shift button, control commands can be input to the circuit board 203 to enable or disable the automatic shift function of the button-indicator instrument device 200. By lightly pressing the upshift or downshift button, control commands can be input to the circuit board 203 to enable or disable the automatic shift function. The current gear and shift mode of the bicycle can be displayed through the LED bead 205 for the rider's convenience.
[0041] 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.
[0042] 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.
[0043] For example, see Figure 6 As shown, the power supply device 400 uses an external battery tube.
[0044] In this technical solution, the external battery tube (or external battery module) is a detachable battery device independent of the main device. It is usually connected to the device through a physical interface or wirelessly to provide additional power. It can provide power support for the operation of the micro motor running device 100 and the key indicator instrument device 200. It also has the advantages of flexible installation and removal, convenient maintenance and upgrade, and optimized heat dissipation and safety.
[0045] For example, see Figure 7 As shown, it also includes a wiring harness 500, which is a one-to-three connection control harness. One end of the wiring harness 500 is connected to the micro motor running device 100, one end is connected to the key indicator instrument device 200, one end is connected to the speed measuring device 300, and one end is connected to the power supply device 400.
[0046] In this technical solution, the power supply device 400 can be conveniently transmitted to the micro motor running device 100, the key indicator instrument device 200 and the speed measuring device 300 through the wiring harness 500, so as to provide power support for their operation.
[0047] See Figure 1 As shown, a bicycle includes an automatic electronic shifter as described in any of the above.
[0048] Bicycles include: road bikes, mountain bikes, folding bikes, touring bikes, or fixed-gear bikes.
[0049] Working principle: Before using the automatic electronic shift controller of this internal derailleur hub, firstly, fix the micro motor running device 100 to one end of the internal derailleur hub shaft, fix the button indicator device 200 to one end of the bicycle handlebars, fix the speed measuring device 300 to the bicycle wheel hub, and fix the power supply device 400 to the bicycle frame. Then, connect the micro motor running device 100, button indicator device 200, speed measuring device 300 and power supply device 400 through the wiring harness 500. After the button indicator device 200 is powered, the automatic shift function can be activated by lightly pressing the automatic shift button. The speed measuring device 300 measures the riding speed, converts it into an electrical signal and transmits it to the circuit board 203. The circuit board 203 then issues corresponding control commands to control the micro motor 105 to extend and retract to a corresponding degree, completing the automatic shift. The automatic electronic shift 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 instrument device 200, the button indicator instrument 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. By setting up a speed measuring device 300, it can automatically perform corresponding gear shifting according to different riding speeds, allowing the rider to achieve multiple gear shifts with just a light press of the automatic shift button, which helps reduce rider fatigue and increase riding comfort.
[0050] 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.
