DETAILED DESCRIPTION

[0019] As shown in the figure, a fingerprint zipper head is provided, wherein the zipper head is integrated with a zipper locking device and a power module 9 for supplying power thereto, wherein the zipper locking device comprises a fingerprint authentication device arranged at the zipper head pull tab 3, and also comprises a stop switch arranged at the zipper head pull tab 1; the fingerprint authentication device comprises a microprocessor 10 and a fingerprint sensor 4; the fingerprint sensor is connected to the stop switch; when the zipper head is installed at the zipper, the pin of the stop switch is embedded between the zipper teeth 8 to fix the position of the pull tab at the zipper 12; when the position of the pull tab at the zipper needs to be changed, first place the finger at the fingerprint sensor of the pull tab, the fingerprint sensor sends the collected fingerprint information to the microprocessor, the microprocessor pre-processes the collected fingerprint information, and performs authentication comparison with the pre-stored fingerprint data, if the fingerprint authentication is successful, the microprocessor sends a control instruction to the drive module of the stop switch to make the pin leave the zipper teeth, and the pull tab can be pulled by the pull tab.

[0020] The battery is located in the inner cavity of the pull head, or in the handle of the pull tab.

[0021] The power module is a miniaturized, low-power power module, including a button battery.

[0022] The microprocessor is arranged at the pull head, or is integrated at the decorative part of the pull tab.

[0023] When the fingerprint is successfully authenticated with the preset fingerprint database, the microprocessor sends an unlocking instruction to the driving module of the travel switch and times the current unlocking time. When the unlocking time is not greater than the threshold, the driving module makes the pin leave the zipper tooth so that the slider can be pulled by the pull tab.

[0024] When the unlocking time is longer than a threshold value, the driving module drives the pin to be inserted back between the zipper teeth so that the slider cannot be pulled by the pull tab.

[0025] The pin member is a locking plate 2, and a protrusion 5 which can be embedded between the zipper teeth is provided on the locking plate surface.

[0026] The driving module comprises a resetting elastic member 6 connected to the pin member. When the zipper head is installed at the zipper, the protrusion of the pin member is driven by the elastic force of the resetting elastic member to be embedded between the zipper teeth.

[0027] The locking plate is a metal part that can be attracted by magnetic force; the driving module includes an electromagnetic coil 7, the direction of the magnetic attraction force of the electromagnetic coil on the locking plate is opposite to the direction of the elastic force of the reset elastic member on the locking plate, and the magnetic attraction force of the electromagnetic coil on the locking plate is greater than the elastic force of the reset elastic member on the locking plate; when the microprocessor sends an unlocking instruction to the driving module of the travel switch, the driving module attracts the locking plate with the magnetic force of the electromagnetic coil, so that the protrusion of the locking plate leaves the zipper teeth so that the slider is unlocked and can be pulled by the pull tab; When the slider unlocking time is greater than a threshold, the microprocessor sends a locking command to the drive module of the stop switch, the electromagnetic coil of the drive module is powered off, and the elastic force of the reset elastic member drives the raised portion of the pin member to embed between the zipper teeth.

[0028] A zipper head system integrated with fingerprint authentication technology, using the above-mentioned fingerprint zipper head, characterized in that: in the zipper head system, a wireless communication module capable of communicating with an external mobile phone is provided at the zipper head, when a large number of fingerprints need to be authenticated, the preset fingerprint data is stored in an APP or mini program of the external mobile phone, and the user performs fingerprint entry and verification operations through the APP or mini program or web user interface; When the number of fingerprints to be authenticated is small, the fingerprint data is stored in the internal memory of the fingerprint authentication device; If the fingerprint authentication fails, the microprocessor controls the indicator light / display screen connected to it to display an error message; When the fingerprint authentication match fails to be verified multiple times in a row, the microprocessor triggers the anti-brute force cracking mechanism, prohibits sending unlocking instructions to the drive module of the travel switch for a preset time and issues an alarm.

[0029] In this example, a charging port 11 for charging the power module is provided at the zipper head, and a low-voltage power supply can also be applied to the zipper to supply power to the zipper head using the built-in wires of the zipper.

[0030] Example: In this example, a fingerprint authentication zipper head structure is proposed, including: 1.1 Shell: Made of high-strength, lightweight materials such as aluminum alloy or stainless steel, with wear-resistant and anti-slip surface treatment.

[0031] 1.2 Fingerprint sensor: embedded inside the shell, specifically in the slider. When zipping, the finger can just press on the slider. Used to collect the user's fingerprint information. The sensor has the characteristics of high precision and fast response to ensure user experience.

[0032] 1.3 Microprocessor: Built into the zipper head, responsible for processing fingerprint information and comparing it with the preset fingerprint database to verify the user's identity.

[0033] 1.4 Power module: adopts miniaturized and low-power design, such as button batteries, to ensure that the zipper head can maintain normal operation after long-term use.

[0034] 1.5 Driver module: used to drive the opening and closing of the stop switch after verifying the fingerprint, and determine whether the zipper can be opened in reality 1.6 Stop switch: Under the action of the drive module, the stop switch moves. When the fingerprint passes through, the stop switch opens and the zipper can be opened normally; when the finger leaves or leaves for a period of time, the stop switch automatically falls to prevent the zipper head from moving, achieving the function of a limit switch. 1.7 Indicator light / display screen: used to display the fingerprint verification result (e.g. green light indicates verification passed, red light indicates verification failed) or other relevant information.

[0035] How this example works: The user places his finger on the fingerprint sensor, which collects the fingerprint information and sends it to the microprocessor.

[0036] The microprocessor pre-processes the collected fingerprint information and compares it with the preset fingerprint database.

[0037] If the fingerprint matches successfully, the microprocessor sends a signal to the drive module, the stop switch opens, and the zipper can be opened normally.

[0038] If the fingerprint matching fails, the microprocessor controls the indicator light / display to display an error message, the stop switch does not respond, and the zipper is prohibited from opening and closing.

[0039] Security features of this example: Multi-user support: The system supports storing multiple fingerprint information, which is convenient for family members or shared users.

[0040] Anti-brute force cracking: The system has an anti-brute force cracking function. When multiple consecutive verification failures occur, it will automatically lock and sound an alarm.

[0041] Low-power design: Uses low-power components and intelligent power management strategies to extend battery life.

[0042] Ease of operation: Ensure that users can easily complete fingerprint entry and verification operations through user interfaces such as APP, mini-programs, and web pages.

[0043] The application scenarios of this example are: - Personal belongings such as school bags, wallets, and cosmetic bags.

[0044] - Office filing cabinets, safes, and other places that require secure locking.

[0045] - Other products that require biometric technology to improve security.

[0046] If the locking plate is set above the zipper, in this example, when the fingerprint authentication is passed, the stop module (locking plate) rises and leaves the restricted area so that the zipper can be opened normally. When the fingerprint does not pass, the stop module automatically falls and gets stuck on the teeth of the zipper, restricting the movement of the zipper head. The default state is the stuck state. It is only opened after fingerprint recognition.
