Description

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 gear hub and an electric-assisted bicycle. Background Technology

[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 internal gear hubs with electronic shifting used in electric-assist bicycles, but 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 with an internal gear hub and an electric-assist bicycle to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic electronic shift controller with an internal gear hub and an electric-assisted bicycle, so as to solve the problems existing in the above-mentioned background art.

[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. The button indicator instrument device includes an upper button cover, a lower button cover, and a circuit board disposed between the upper button cover and the lower button cover. The button indicator instrument device is connected to a micro motor through a driver.

[0008] One side of the button cover is provided with buttons and LEDs that are electrically connected to the circuit board. The buttons include an automatic shift button, an upshift button, and a downshift button.

[0009] The circuit board is electrically connected to the controller of the electric-assisted bicycle, and the controller of the electric-assisted bicycle is electrically connected to the built-in sensor of the electric-assisted bicycle motor.

[0010] Furthermore, the outer shell body and the micro motor lower cover are connected by positioning rivets, the movable conversion lever is movably sleeved on the positioning rivets, one end of the movable conversion lever is movably connected to the telescopic rod of the micro motor, and the other end is movably connected to the pin of the internal speed hub.

[0011] Furthermore, a micro motor rear cover is fitted onto one side of the micro motor, and the micro motor rear cover is fixedly connected to the outer shell body.

[0012] Furthermore, it also includes a wiring harness, which is a one-to-two connection control harness. One end of the harness is connected to the micro motor running device, one end is connected to the button indicator instrument device, and the other end is connected to the controller of the electric-assisted bicycle.

[0013] Furthermore, a mounting ring is fixed to the bottom of the button cover, and the inner diameter of the mounting ring matches the outer diameter of the bicycle handlebar.

[0014] Furthermore, the wiring harness has three terminals, each with a different structure, and each terminal is adapted to the wiring ports on the micro motor running device, the button indicator device, and the controller of the electric-assisted bicycle.

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.

[0028] 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.

[0029] This utility model provides, for example Figure 1-6 The automatic electronic shift controller for an internal deceleration hub shown includes:

[0030] 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.

[0031] 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.

[0032] 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 an automatic shift button, an upshift button, and a downshift button. By lightly pressing the automatic shift button, a control command can be input to the circuit board 203 to enable or disable the automatic shift function of the button indicator instrument 200. By lightly pressing the upshift or downshift button, a control command can be input to the circuit board 203 to enable or disable the automatic shift function. The LED 205 can display the current gear and shift mode of the bicycle for easy observation by the rider.

[0033] Circuit board 203 is electrically connected to the controller of the electric-assisted bicycle, and the controller of the electric-assisted bicycle is electrically connected to the built-in sensor of the electric-assisted bicycle motor. The motor speed is measured by the built-in sensor, and the actual speed of the wheel can be calculated based on the reduction ratio between the motor and the wheel. Then, the riding speed of the electric-assisted bicycle can be calculated based on the circumference of the wheel. The controller of the electric-assisted bicycle transmits the riding speed to circuit board 203 in the form of an electrical signal. 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, circuit board 203 will receive a signal again and output a command, and the hub will up a gear again. This allows the hub to automatically shift gears according to the change in riding speed, making the shifting process smoother and avoiding the rider's frequent operation of the button indicator device 200, thus improving riding comfort.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] In this technical solution, the power of the controller of the electric-assisted bicycle is conveniently transmitted to the micro-motor running device 100 and the key indicator instrument device 200 through the wiring harness 300, so as to provide power support for their operation.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] An electric-assisted bicycle comprising an automatic electronic shifting controller with an internal derailleur hub as described above.

[0045] 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.

[0046] For example, the battery of the electric-assisted bicycle is a lithium battery or a lead-acid battery, and the battery of the electric-assisted bicycle is electrically connected to the controller of the electric-assisted bicycle.

[0047] 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, 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 automatic shift function can be activated by lightly pressing the automatic shift button. The built-in sensor of the electric-assisted bicycle motor measures the riding speed, converts it into an electrical signal and transmits it to the circuit board 203. The circuit board 203 issues corresponding control commands to control the micro motor 105 to extend and retract to a corresponding degree, thus completing the automatic shift. This internal derailleur hub features an advanced, compact, and user-friendly automatic electronic gear control system. It incorporates a micro-motor operating device and a button-operated indicator. The button-operated indicator controls the micro-motor, causing it to automatically extend and retract to push a movable shift lever. This lever then pushes the hub's pin, achieving gear shifting. The system uses a built-in sensor in the electric bicycle's motor to measure riding speed and automatically shifts gears accordingly. Riders can perform multiple gear changes with a single press of the automatic shift button, reducing fatigue and increasing riding comfort. The micro-motor operating device, button-operated indicator, and electric bicycle controller are electrically connected via a wiring harness, allowing direct power to the electronic gearbox from the controller. This eliminates the need for an external battery pack and charging, increasing the frequency of use of the electronic gear controller, reducing external components, and enhancing the aesthetics of the electric bicycle.

[0048] 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.
