Description
Technical Field
[0001] This utility model relates to the field of bicycle derailleur technology, and in particular to a low-power identification system for a wireless bicycle derailleur. Background Technology
[0002] With continuous technological advancements, modern bicycles are gradually transforming towards intelligence and convenience. Wireless derailleur systems, a significant outcome of this transformation, have been widely adopted in the market. These systems precisely and quickly control the derailleurs via wireless signals, significantly improving riding convenience and experience. Compared to traditional mechanical derailleurs, wireless derailleurs eliminate complex mechanical connections, resulting in a simpler and more aesthetically pleasing bicycle design. Furthermore, shifting gears becomes much easier and more effortless during actual riding. The advantages of wireless derailleurs lie in eliminating complex mechanical connections, leading to a simpler and more aesthetically pleasing bicycle design, and easier shifting during actual use.
[0003] In existing technologies, due to the size and portability requirements of wireless gearboxes, the battery capacity is limited. Therefore, incorporating low-power design into the device is crucial. Because existing wireless gearbox systems consume a lot of energy in the identification and control modules, battery life is shortened. Frequent battery replacements not only increase user costs but also affect the convenience of riding. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a low-power identification system for a bicycle wireless gearbox.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A low-power identification system for use with wireless bicycle derailleurs, the system comprising:
[0007] The wake-up module is used to detect at least one operating parameter of the bicycle to determine the actual operating state of the bicycle, and selectively activate or deactivate the identification module and control module according to the operating state information of the bicycle to achieve a low power consumption state.
[0008] The identity recognition module is used to obtain the user's identity information, identify the user's identity, and send an identification signal;
[0009] The control module receives the identification signal from the identification module, parses the content of the identification signal, and controls the operation of turning the bicycle's wireless gearbox on or off based on the parsing result, thereby realizing intelligent control of the bicycle's gear shifting function.
[0010] Furthermore, the wake-up module monitors the actual operating status of the bicycle, including but not limited to acceleration, speed, and vibration, in order to activate or deactivate the system.
[0011] Furthermore, the actual operating state of the bicycle includes both a moving state and a stationary state.
[0012] Furthermore, the technologies used by the identity recognition module for identity recognition include, but are not limited to, fingerprint recognition, facial recognition, RFID, radio frequency identification, and UWB technology.
[0013] Furthermore, the identity recognition module has a storage unit that stores the recognition conditions.
[0014] Furthermore, the identification conditions stored in the storage unit include those provided by the user himself or other users authorized by the user.
[0015] Furthermore, the control module receives the identification signal sent by the identification module and determines whether it matches the identification conditions stored in the identification module, and then sends a corresponding identification success or failure signal.
[0016] A low-power identification method for use with wireless derailleurs in bicycles includes the following steps:
[0017] The wake-up module detects the bicycle's operating parameters to determine its actual operating status.
[0018] The wake-up module automatically activates or deactivates the system based on the actual operating status of the bicycle.
[0019] The identity recognition module is used to acquire and verify the user's identity. If the verification is successful, an identification signal is sent.
[0020] The control module receives the identification signal and compares it with the stored identification conditions. If they match, it sends a control signal to allow the wireless gearbox to operate.
[0021] Furthermore, the wake-up module detects the bicycle's operating parameters using speed and acceleration sensors.
[0022] Furthermore, the wake-up module detects the bicycle's operating parameters to determine its actual operating status, specifically including:
[0023] If the speed sensor detects that the bicycle speed is zero and the acceleration sensor detects that the acceleration change is within the threshold range, the bicycle is considered to be stationary.
[0024] If the speed sensor detects that the bicycle speed is greater than zero or the acceleration sensor detects that the acceleration change exceeds the threshold range, the bicycle is considered to be in motion.
[0025] Furthermore, the wake-up module automatically activates or deactivates the system based on the actual operating status of the bicycle, including the following situations:
[0026] When the bicycle is stationary: the wake-up module enters low-power mode and shuts down the identity recognition module and the control module;
[0027] When the bicycle changes from a stationary state to a moving state, the wake-up module wakes up the identity recognition module and the control module.
[0028] Furthermore, the identity recognition module obtains the user's identity; if the identity recognition conditions are met, a corresponding recognition signal is issued; otherwise, no action is taken.
[0029] Furthermore, the control module receives the identification signal from the identity recognition module. If the signal matches the identification conditions stored in the storage unit, the module sends a signal indicating successful identification; otherwise, no action is taken.
[0030] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

Through the identification system, only authorized users are allowed to operate the wireless derailleur, preventing unauthorized use and misoperation, and greatly improving the security and anti-theft performance of the bicycle.
[0032] 2. The low-power identification system for wireless gearboxes of this invention is simple and convenient to operate. Users only need to verify their identity once to easily use the wireless gearbox function of their bicycle. The identification process is fast and does not affect the user's normal riding experience, thus improving user convenience.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0044] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.
[0045] Please see Figure 1This utility model discloses a low-power identification system for a wireless bicycle gearbox. The system includes a wake-up module 100, an identification module 200, a control module 300, and a power module 400. The wake-up module 100 detects at least one operating parameter of the bicycle to determine its actual operating state. Based on this information, it selectively activates or deactivates the identification module 200 and the control module 300 to achieve a low-power state. The identification module 200 acquires the user's identity information, identifies the user, and sends an identification signal. The control module 300 receives the identification signal from the identification module 200, parses the signal, and controls the activation or deactivation of the wireless gearbox based on the parsing result, thereby achieving intelligent control of the bicycle's gear shifting function. The power module 400 provides electrical energy.
[0046] Specifically, the wake-up module 100 monitors the actual operating state of the bicycle, including but not limited to acceleration, speed, and vibration, to activate or deactivate the system. In this embodiment, the wake-up module 100 uses an accelerometer and a speed sensor to monitor the actual operating state of the bicycle by detecting its acceleration and speed. Furthermore, the actual operating state of the bicycle includes both a moving state and a stationary state.
[0047] Furthermore, the identity recognition module 200 employs technologies including, but not limited to, fingerprint recognition, facial recognition, RFID, radio frequency identification, and UWB technology for identity recognition. Specifically, the identity recognition module 200 has a storage unit that stores recognition conditions. In this embodiment, the recognition conditions specifically refer to information or standards used to verify the user's identity. These conditions can be one or a combination of several forms, such as biometric information (e.g., fingerprint information, facial information), identity authentication codes (e.g., preset passwords, dynamic verification codes), physical identification information (e.g., RFID tag information, NFC chip information), and authorization information. The stored recognition conditions also include those provided by the user themselves and by other users authorized by the user.
[0048] The control module 300 receives the identification signal from the identification module and determines whether it matches the identification conditions stored in the identification module, issuing a corresponding success or failure signal. Specifically, after receiving the identification signal, the control module 300 compares it with the identification conditions stored in the identification module 200's storage unit. Based on the comparison result, the control module 300 issues a corresponding success or failure signal. If the identification signal matches the stored identification conditions, it indicates successful user authentication, and the control module 300 issues a success signal, potentially further controlling the activation of the bicycle's wireless gearshift or performing other related operations. If the identification signal does not match the stored identification conditions, it indicates failed user authentication, and the control module 300 issues a failure signal, potentially preventing the activation of the bicycle's wireless gearshift or performing other related operations.
[0049] It is important to note that the built-in wake-up module 100 of this system can accurately monitor the bicycle's operating status, especially when the bicycle starts moving from a stationary state; the wake-up module 100 can immediately detect this change. Based on the information provided by the wake-up module 100, the identity recognition module 200 is intelligently activated. This design ensures that identity verification is only performed when the bicycle is about to start moving, improving system response speed and avoiding unnecessary energy consumption. Furthermore, the identity recognition module 200 can quickly acquire and identify the user's identity information, ensuring that only authorized users can activate the gear shifting function.
[0050] Please see Figure 2 This utility model also discloses a low-power identification method for use in bicycle wireless derailleurs, comprising the following steps:
[0051] S101: The wake-up module detects the bicycle's operating parameters to determine its actual operating status;
[0052] S102: The wake-up module automatically activates or deactivates the system based on the actual operating status of the bicycle;
[0053] S103: Use the identity recognition module to obtain and verify the user's identity. If the verification is successful, an identification signal will be sent.
[0054] S104: The control module receives the identification signal and compares it with the stored identification conditions. If they match, it sends a control signal to allow the wireless gearbox to operate.
[0055] This method specifically includes the following steps:
[0056] S101: The wake-up module 100 detects the bicycle's operating parameters to determine its actual operating state. Specifically, the wake-up module 100 detects the bicycle's operating parameters using a speed sensor and an acceleration sensor, and determines whether the bicycle is stationary or in motion based on the corresponding values displayed on the speed sensor and acceleration sensor. The specific determination method is as follows: if the speed sensor detects that the bicycle's speed is zero and the acceleration sensor detects that the acceleration change is within a set threshold range, then the bicycle is considered to be stationary; if the speed sensor detects that the bicycle's speed is greater than zero or the acceleration sensor detects that the acceleration change exceeds a set threshold range, then the bicycle is considered to be in motion.
[0057] S102: The wake-up module 100 automatically activates or deactivates the system based on the actual operating status of the bicycle. Specifically, this includes the following:
[0058] When the bicycle is stationary: the wake-up module 100 enters a low-power mode and shuts down the identification module 200 and the control module 300;
[0059] When the bicycle changes from a stationary state to a moving state, the wake-up module 100 wakes up the identity recognition module 200 and the control module 300.
[0060] S103: The identity recognition module 200 is used to acquire and verify the user's identity. If the verification is successful, an identification signal is sent; otherwise, no action is taken. Specifically, when the wake-up module 100 detects that the bicycle has changed from a stationary state to a moving state, the identity recognition module 200 is activated. The identity recognition module 200 reads the user's identity information. After acquiring the identity information, it is converted into an identification signal and sent to the control module 300. This can be done through serial communication, BLE (Bluetooth Low Energy), or other transmission methods.
[0061] S104: The control module 300 receives the identification signal and compares it with the stored identification conditions. If they match, it sends a control signal to allow the wireless gearbox to operate; otherwise, no action is taken. In this embodiment, the identity recognition module 200 compares the read user identity information with the stored authorized user information. If the user's identity meets the identification conditions, a corresponding identification signal is sent, allowing the user to operate the wireless gearbox. In other embodiments, if the user's identity does not meet the identification conditions, no action is taken, the gearbox remains locked, and an alarm may be issued to notify the user.
[0062] Please see Figure 3 According to the low-power identification method for bicycle wireless gearboxes of this utility model, the working states of each module are as follows when the bicycle is stationary or in motion:
[0063] 1. At rest:
[0064] Wake-up module 100: Low-power operating mode, periodically wakes up and reads sensor data to check the bicycle status;
[0065] Identity recognition module 200: Closed, no operation performed;
[0066] Control module 300: Off state, system remains locked.
[0067] 2. Action occurs:
[0068] Wake-up module 100: Working mode, detects that the bicycle has changed from a stationary state to a moving state;
[0069] Identity recognition module 200: In the startup state, it reads and verifies user identity information;
[0070] Control module 300: Start-up state, ready to receive the identity recognition result to determine whether to allow operation of the wireless gearbox.
[0071] Furthermore, when the identity recognition module 200 is in the state of recognizing the user's identity, the working states of each module are as follows:
[0072] 1. Use by car owners
[0073] Wake-up module 100: Working mode, keeping the system running;
[0074] Identity recognition module 200: It shuts down after successful recognition and no longer consumes power after identity verification is completed;
[0075] Control module 300: In the start state, allowing users to operate the wireless gearbox.
[0076] 2. Used by non-owners
[0077] Wake-up module 100: Working mode, keeping the system running;
[0078] Identity recognition module 200: In the startup state, it performs identity verification. If the verification fails, it remains running to prevent unauthorized operations.
[0079] Control module 300: In the off state, operation of the wireless gearbox is not allowed, and the system remains locked.
[0080] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
