Detailed implementation manners
[0029] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects according to the present utility model.
[0030] Refer to Figure 1-3 , a novel electronic lock provided in this embodiment includes a main control module, a power supply module, a motor drive module, and an acquisition module. The main control module is electrically connected to the motor drive module and the acquisition module respectively. A detachable connection is adopted between the main control module and the acquisition module. The power supply module is electrically connected to the main control module, the motor drive module, and the acquisition module respectively; the acquisition module is used to collect unlocking information and transmit it to the main control module, and the main control module is used to transmit a control instruction to the motor drive module according to the unlocking information.
[0031] In this embodiment, the power supply module provides stable power for the electronic lock to ensure that the main control module, the motor drive module, and the acquisition module can work normally. When the user needs to unlock the electronic lock, the acquisition module starts to work, collects the user's unlocking information. The unlocking information includes but is not limited to sound, password, fingerprint, and card - swiping. After the acquisition module collects the user's unlocking information, it converts the collected information into a binary signal and transmits the binary signal to the main control module. The main control module compares the unlocking information collected by the acquisition module with the password. If the unlocking information matches the password, it controls the motor drive module to drive the motor J2 to complete the unlocking action. Among them, the detachable connection between the acquisition module and the main control module enables the user to select the unlocking method according to their own needs, which is extremely flexible.
[0032] Reference Figure 1 Figure 1 , in a further embodiment of the present utility model, the main control module includes a controller U16, a horizontal female socket, a first switch S1, a first resistor R701, and a third resistor R703. The output terminal of the power supply module is connected to the ninth pin of the controller U16. The tenth pin of the controller U16 is connected to one end of the first switch S1. The other end of the first switch S1 is connected to one end of the third resistor R703. The other end of the third resistor R703 is grounded. The first pin of the horizontal female socket is grounded. The fifth pin of the horizontal female socket is connected to one end of the first resistor R701. The other end of the first resistor R701 is grounded. The sixth pin of the horizontal female socket is connected to the fifteenth pin of the controller U16. The seventh pin of the horizontal female socket is connected to the eleventh pin of the controller U16. The ninth pin of the horizontal female socket is connected to the non-step-down VCC terminal of the power supply module.
[0033]
[0033] Among them, the sixth pin and the seventh pin of the horizontal female socket are respectively connected to the fifteenth pin and the eleventh pin of the controller U16. When the acquisition module is connected to the main control module through the horizontal female socket, the control chip in the acquisition module can transmit signals to the controller U16 through the sixth pin and the seventh pin of the horizontal female socket. The first pin of the horizontal female socket is grounded to provide a voltage reference point. The first resistor R701 and the third resistor R703 are used to limit the current to avoid overcurrent damage to electrical components caused by excessive current when the circuit is grounded instantaneously. The first switch S1 is a manual reset switch.
[0034]
[0034] In this embodiment, the electronic lock system obtains the unlocking information through the acquisition module. The main control module verifies the unlocking information and controls the motor drive module to perform the unlocking action according to the verification result. The system adopts a modular design, especially the detachable connection between the main control module and the acquisition module, which is convenient for maintenance and upgrade. Among them, the controller is the core of the entire electronic lock system, responsible for receiving the unlocking information from the acquisition module, performing logical judgment, and controlling the motor drive module to perform the unlocking action. At the same time, it is also responsible for the overall operation and status monitoring of the system. The first switch is used to manually control the power on and off of the main control module, which is convenient for debugging or shutting down the system in case of emergency. The horizontal female socket serves as an interface between the main control module and the acquisition module to achieve the detachable connection between the two. At the same time, through different pins of the horizontal female socket, signal and power transmission can be realized. The connection between the electronic lock and the external power supply through the horizontal female socket provides an emergency power supply for the electronic lock to ensure that the electronic lock can still work normally in case of power failure, improving the reliability of the electronic lock.
[0035] In a further embodiment of the present utility model, the main control module further includes a reset circuit. The reset circuit includes a first capacitor C701 and a second resistor R702. One end of the second resistor R702 is connected to the ninth pin of the controller U16, and the other end of the second resistor R702 is connected to the fourth pin of the controller U16. One end of the first capacitor C701 is connected to the fourth pin, and the other end of the first capacitor C701 is grounded.
[0036] After the controller is powered on, since the voltage across the first capacitor C701 cannot change suddenly, the first capacitor C701 starts to charge. In the initial stage of charging, due to the relatively low capacitor voltage, the node voltage connected to the ninth pin of the controller U16 through the resistor R702 will also be relatively low. If this low voltage meets the reset trigger condition of the controller U16, then the controller will enter the reset state; as the capacitor C701 continues to charge, the node voltage gradually increases. When it exceeds the reset trigger threshold, the reset signal disappears, and the controller exits the reset state and starts to work normally.
[0037] In this embodiment, a reset circuit is provided in the main control module. When the main control module of the electronic lock encounters an abnormal situation, the reset circuit can trigger a system restart to restore the main control module to its initial normal working state. At the same time, when the power supply voltage is unstable or there is an abnormal current in the circuit, the main control module and other circuit components are protected through a reset operation to avoid damage caused by circuit abnormalities. Through the automatic reset function, the reset circuit can significantly reduce the risk of the system crashing due to software errors or external interference, thereby improving the stability of the entire electronic lock system. Moreover, the reset circuit can quickly reset the system to a known safe state to prevent the expansion of faults or more serious consequences.

The other end of the fourth capacitor C704 is grounded, and the other end of the fifth capacitor C705 is grounded;
[0040] The first pin of the built-in power supply J1 is connected to the anode of the first diode D1, and the second pin of the built-in power supply J1 is grounded.

[0042] In this embodiment, the power supply module steps down the voltage provided by the built-in power supply J1 through the first step-down chip U17. The power supply is input to the first pin of the first step-down chip U17, and after being stepped down by the first step-down chip U17 to the operating voltage required by the main control module, the acquisition module, and the motor drive module, it is output from the third pin of the first step-down chip U17 to the main control module, the acquisition module, and the motor drive module. The second capacitor C702, the third capacitor C703, the fourth capacitor C704, and the fifth capacitor C705 are used to filter the power supply, reduce the noise and interference in the power supply, and improve the stability of the power supply. The first diode D1 plays a protective role to prevent the reverse flow of current and ensure the safety of the power supply module. The built-in power supply J1 provides the original electrical energy for the entire power supply module. Its first pin is connected to the step-down chip through the first diode D1, and its second pin is grounded to form a complete power supply loop.

The fifth pin of the motor drive chip U18 is respectively connected to one end of the sixth capacitor C706 and one end of the motor J2. The eighth pin of the motor drive chip U18 is respectively connected to the other end of the sixth capacitor C706 and the other end of the motor J2. The sixth pin and the seventh pin of the motor drive chip U18 are both grounded.
[0044] In this embodiment, the motor drive chip U18 is responsible for receiving the unlocking instruction from the main control module and precisely controlling the rotation of the motor J2. This ensures the accuracy and reliability of the unlocking action. The fourth resistor R704 and the fifth resistor R705 are respectively connected to the second and third pins of the motor drive chip U18 and the corresponding pins of the controller U16 for stable signal transmission and resistance matching, reducing signal attenuation and interference.
[0045] Please refer to Figures 4-10 , in a further embodiment of the present utility model, the acquisition module includes a control chip, a step-down chip, a horizontal female socket, a plug, and an information collector.

The sound collector collects the user's voice through the radio receiver and generates an analog signal, and converts the analog signal generated by the radio receiver into a digital signal through the sound chip, and then uses the control chip to convert the digital signal into a binary signal and transmit it to the main control module for comparison.

[0059] The present utility model provides a novel electronic lock. By adopting a detachable connection between the acquisition module and the main control module, the user can replace different modules according to their own needs to select the unlocking method. At the same time, multiple unlocking methods can coexist through a cascading method. Its operating principle is as follows:
[0060] When the electronic lock is in the single-mode unlocking state, the user can select any acquisition module, connect the plug of the selected acquisition module to the horizontal female socket of the main control module, and input the corresponding information using the selected acquisition module. After the acquisition module collects the information input by the user, it processes and converts the information into a binary signal and transmits the signal to the main control module. The main control module compares the binary signal with the pre-set password information. If the comparison result is correct, it drives the motor through the motor drive module to complete the unlocking action.
[0061] When the electronic lock is in the state of two or more coexisting unlocking modes, the user first selects a certain number of acquisition modules, connects the plugs of the selected acquisition modules to the horizontal female socket in sequence to make the selected acquisition modules connected in series, and inputs the corresponding unlocking information on each acquisition module respectively. After each acquisition module collects the unlocking information input by the user, it uses the control chip to convert the unlocking information into a binary signal and transmits it to the main control chip. The main control chip compares the binary signals transmitted from each acquisition module with the pre-set passwords in sequence. If all the comparison results are correct, it drives the motor through the motor drive module to complete the unlocking action.
