[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] 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.

[0029] This utility model proposes a fingerprint padlock. The technical solution adopted is mainly based on Find My technology, combined with biometric identification and intelligent positioning, to improve the security and convenience of the fingerprint padlock. This Find My fingerprint padlock not only ensures that only the user can unlock it, but also, in the event of loss, uses Find My technology to accurately locate the lost item, helping to quickly recover it. It provides an intelligent and reliable way to protect valuables, enhancing item security.

[0030] Specifically, please refer to Figure 1 A preferred embodiment of the fingerprint padlock of this utility model includes: a Bluetooth main control chip, a charging module, a motor module, an indicator light module, a sound module, a fingerprint module and a motion detection module connected to the Bluetooth main control chip, and the Bluetooth main control chip is also connected to a smart terminal in the Find My network.

[0031] In this embodiment, the smart terminal is, for example, an Apple mobile phone, an iPad, or other terminal with the Find My function. The following will first combine... Figure 2 and Figure 3 This article will use an Apple iPhone as an example to introduce the Find My feature.

[0032] To use the Find My feature, you first need to pair the fingerprint padlock's controller with your Apple phone. The pairing process is as follows: Figure 2 As shown. After pairing is complete, the user can enable location services. The location service process on an Apple phone is as follows: Figure 3 As shown.

[0033] When the fingerprint padlock is lost, the Bluetooth controller will transmit Bluetooth signals at regular intervals. These signals contain the device's identification information. Nearby Apple devices or other devices that support Find My network and have the corresponding function enabled will receive this signal and be able to recognize the presence of the fingerprint padlock with Find My functionality.

[0034] When a user locates a fingerprint padlock using the Find My app on an Apple device, the search command is transmitted via Bluetooth. Upon receiving the search command from a nearby Apple device, the chip transmits its stored location information and other data to that device via Bluetooth. The Apple device then uploads the data to the iCloud server and finally sends the location information back to the user's app, helping the user determine the approximate location of the fingerprint padlock.

[0035] In this embodiment, the Bluetooth master control chip is an OM6626B chip, and the circuit structure of the Bluetooth master control chip is as follows. Figure 4 As shown.

[0036] The OM6626B chip is a smart Bluetooth master control chip responsible for managing wireless communication and controlling various functions of the padlock. This chip verifies fingerprint information through a fingerprint recognition module, while simultaneously controlling the buzzer to emit an alert sound and the LED indicator to display the status. Furthermore, the OM6626B chip works in conjunction with an accelerometer for motion detection.

[0037] Furthermore, such as Figure 5 As shown, in this embodiment, the motion detection module includes a chip U3, resistors R28 and R29, capacitors C7 and C8. Pin 2 of chip U3 is connected to one end of resistor R28 and pin 11 of the Bluetooth master control chip. The other end of resistor R28 is connected to one end of resistor R29 and pin 24 of the Bluetooth master control chip. The other end of resistor R29 is connected to pin 12 of chip U3 and pin 10 of the Bluetooth master control chip. Pin 3 of chip U3 is connected to pin 24 of the Bluetooth master control chip and one end of capacitor C8. Pin 7 of chip U3 is connected to pin 24 of the Bluetooth master control chip and one end of capacitor C7. The other end of capacitor C7, the other end of capacitor C8, pin 8 of chip U3, and pin 9 of the chip are grounded.

[0038] In this embodiment, the fingerprint padlock is designed with a motion detection function. When someone else's Find My device is mixed into the user's personal belongings and tracks them for a certain period of time (3 days) while in a separated state (i.e., the device is far from the owner's device), the device will automatically activate the accelerometer (gsensor) to detect whether movement has occurred. Once movement is detected, the device will emit an sound to remind the user that they are being tracked by the Find My device. Conversely, this function can also detect whether the user's device has been secretly taken by someone else.

[0039] Furthermore, in this embodiment, the sound-generating module includes a chip U1, and the chip U1 is model MLT5025.

[0040] like Figure 6 As shown, the sound-generating module also includes diode D3, MOSFET Q2, resistor R6, and resistor R8. Pin 1 of chip U1 is connected to pin 24 of the Bluetooth master control chip and the cathode of diode D3. Pin 2 of chip U1 is connected to the anode of diode D3 and the collector of MOSFET Q2. The base of MOSFET Q2 is connected to one end of resistor R6 and one end of resistor R8. The other end of resistor R6 is connected to pin 17 of the Bluetooth master control chip. The other end of resistor R8 and the emitter of MOSFET Q2 are grounded.

[0041] In this embodiment, the generating module uses a buzzer, which is mainly used in fingerprint padlocks to provide audible feedback, indicating the user's operation results or device status. When fingerprint verification is successful, the buzzer emits a short beep to confirm unlocking; when verification fails or other operational abnormalities occur, the buzzer emits a continuous warning sound to alert the user. Furthermore, when items are lost, the buzzer can also help the user locate them by emitting sound, further improving the device's practicality and convenience.

[0042] Please refer to Figure 7 In this embodiment, the indicator module includes LED1, LED2, LED3, resistors R1, R9, and R10. The cathodes of LED1, LED2, and LED3 are grounded. The anodes of LED1, LED2, and LED3 are respectively connected to one end of resistor R1, one end of resistor R9, and one end of resistor R10. The other end of resistor R1 is connected to pin 29 of the Bluetooth master control chip. The other end of resistor R9 is connected to pin 30 of the Bluetooth master control chip. One end of resistor R10 is connected to pin 31 of the Bluetooth master control chip.

[0043] In this embodiment, the fingerprint padlock is equipped with three indicator lights: red, green, and blue, representing different states. Green indicates successful verification and the lock is unlocked; red indicates verification failure or device malfunction; and blue displays other device states, such as standby or Bluetooth connection. These indicator lights help users quickly understand the lock's working status.

[0044] In this embodiment, the motor module includes a chip U4, which is of model MX116L.

[0045] Please refer to Figure 8 The motor module further includes resistors R11, R12, R13, and R23, capacitors C2, C6, and C19. Pin 1 of chip U4 is connected to one end of capacitor C2, and the other end of capacitor C2 is connected to pin 6 of chip U4. Pin 2 of chip U4 is connected to one end of resistor R23 and one end of resistor R12. The other end of resistor R23 is connected to pin 2 of the Bluetooth master control chip. The other end of capacitor C19 and the other end of resistor R12 are grounded. Pin 3 of chip U4 is connected to one end of resistor R13 and pin 23 of the Bluetooth master control chip. The other end of resistor R13 is grounded. Pin 4 of chip U4 is connected to one end of resistor R11 and pin 22 of the Bluetooth master control chip. The other end of resistor R11 is grounded.

[0046] This embodiment of the fingerprint padlock uses an MX116L drive motor with forward and reverse rotation to achieve automatic unlocking and locking. Upon successful fingerprint verification, the motor receives a command and starts, rotating to either the unlocked or locked state. This avoids the manual operation required by traditional mechanical locks.

[0047] In this embodiment, the fingerprint padlock connects to the charging management IC (4054) via a TYPE-C interface to enable battery charging. The LN6206P332MR and LN6206P182MR are used to regulate the battery voltage to 3.3V and 1.8V respectively, meeting the voltage requirements of various system components. The circuit structure of the charging module in this embodiment is as follows: Figure 9 As shown.

[0048] In this embodiment, the fingerprint module includes a chip U6, and the model of the chip U6 is FPC1028AP.

[0049] The fingerprint module in the fingerprint padlock provides a highly secure identity verification function through biometric recognition technology. Users scan their fingerprints, and the module compares the collected fingerprint with a pre-stored fingerprint template. Only users whose identities match can unlock the padlock. This module not only improves the security of the padlock, avoiding the risk of leakage associated with traditional keys or passwords, but also enables a convenient contactless unlocking method, enhancing ease of use and the intelligent user experience. The circuit structure of the fingerprint module is as follows... Figure 10 As shown.
