Description

Technical Field

[0001] This utility model relates to the field of lock equipment technology, and in particular to a novel locking and unlocking mechanism and its application in a lock cabinet. Background Technology

[0002] Lock cabinets are widely used in modern warehouse management, public facility services, and the storage of important materials. Traditional lock cabinets mostly use mechanical locks for locking and unlocking operations, relying on mechanical structures such as keys and combination locks to achieve locking and unlocking.

[0003] In scenarios requiring frequent opening and closing of lock cabinets with extremely high security requirements, such as locations storing important documents, valuables, or confidential information, traditional key-based unlocking methods fall short in both convenience and security. Furthermore, while some existing smart locks incorporate electronic unlocking, most still rely on motor-driven mechanisms for locking and unlocking. Motor-driven structures are relatively complex, containing gears, drive belts, and other components, increasing manufacturing costs and leading to high precision requirements and a higher failure rate. Additionally, the slow response speed during motor startup and operation fails to meet the demands for rapid access. Moreover, some existing electronic locks offer limited status displays, failing to intuitively show users and maintenance personnel the lock's operational status, hindering timely problem detection and resolution, and resulting in a poor overall user experience. Therefore, developing a safe, convenient, and efficient new locking and unlocking mechanism and its application in lock cabinets is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the prior art by proposing a novel locking / unlocking mechanism and its application in lock cabinets. Through a unique lock seat structure and a mature electromagnetic induction principle, it achieves efficient and reliable locking / unlocking operations. Compared to traditional mechanical locking / unlocking methods, this solution offers significant advantages such as rapid action, high reliability, and fast response. It is suitable for various scenarios with high requirements for security and operational efficiency, such as intelligent lockers, filing cabinets, and cabinets for storing important materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel locking and unlocking mechanism and its application in a lock cabinet include a lock base and a smart lock body. The lock base has a placement slot adapted to the smart lock body, and the smart lock body is placed in the placement slot on the lock base. The side wall of the smart lock body has a lock groove. A cabinet lock bolt assembly is installed in the lock base. The cabinet lock bolt assembly extends into the lock groove to fix the smart lock body in the lock base. A PCBA board is installed on the lock base, and a status display device controlled by the PCBA board is installed inside the lock base.

[0007] Preferably, the cabinet lock pin assembly includes a rear cover plate mounted on the lock base, an mounting frame mounted on the rear cover plate, an electromagnet mounted inside the mounting frame, a magnetic rod slidably mounted inside the electromagnet, and a lock pin body that is fixedly connected to the magnetic rod through the mounting frame.

[0008] Preferably, the side wall of the mounting frame is provided with a sliding opening, and the locking pin body is slidably connected to and adapted to the sliding opening.

[0009] Preferably, the PCBA board integrates a microprocessor, a power management module, a communication module, and a driver circuit.

[0010] Preferably, the status display component includes multiple sets of tri-color LED beads evenly distributed on the outer edge of the lock base, the outer edge of the lock base is made of high light transmittance PC material, and the PCBA board integrates a driver chip for driving the tri-color LED beads to emit light.

[0011] A lock cabinet includes a cabinet body, an installation plate inside the cabinet body, an array of locking and unlocking mechanisms mounted on the installation plate, and a door connected to the outside of the lock cabinet via hinges. A fingerprint recognition module and a facial recognition module are installed on the door.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This technical solution abandons the complex mechanical transmission structure of traditional mechanical locks and the multi-component transmission system of motor-driven electronic locks. Based on the mature principle of electromagnetic induction, the core components include only a few mechanical structures such as electromagnets and lock pins. This reduces failures caused by component wear and decreased precision, lowers the probability of mechanical failures, and extends the service life of the lock cabinet. Electromagnets have the characteristic of generating magnetic force instantaneously when energized and rapidly disappearing when de-energized. When the system receives an unlocking or locking command, the electromagnet can respond quickly, driving the lock pin to complete the unlocking and locking operation in a short time. Compared with traditional mechanical locks and motor-driven electronic locks, this significantly shortens the operation time. By designing a color indicator function on the lock base, the operating status of the lock can be intuitively displayed to users and maintenance personnel, improving management efficiency and the timeliness of maintenance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-6A novel locking and unlocking mechanism includes a lock base 3 and a smart lock body 2. The lock base 3 has a placement slot adapted to the smart lock body 2, which is placed within the slot. The side wall of the smart lock body 2 has a lock groove 4. A cabinet lock pin assembly is installed in the lock base 3, extending into the lock groove 4 to fix the smart lock body 2 within the lock base 3. The cabinet lock pin assembly includes a rear sealing plate 6 mounted on the lock base 3, with a mounting frame 7 installed on the rear sealing plate 6. An electromagnet 8 is installed within the mounting frame 7. The electromagnet 8, as the core driving component of the locking and unlocking mechanism, is made of high-performance electromagnetic materials, possessing high permeability and low remanence. It can quickly generate a strong and stable magnetic force when energized, and the magnetic force disappears rapidly when de-energized. The external dimensions of the electromagnet 8 are customized according to the internal installation space of the lock base 3. The electromagnet 8 has two ends respectively... The electromagnet 8 is connected to a power line, and the generation and direction of magnetic force are achieved by controlling the on / off state and direction of the current. The coil of the electromagnet 8 adopts a special winding process to improve the electromagnetic conversion efficiency. The electromagnet 8 is installed in a specific position inside the lock seat 3 and is fixed by brackets and fasteners to ensure that it will not be displaced during operation. A magnetic rod 9 is slidably installed inside the electromagnet 8. The magnetic rod 9 is made of magnetic material and has high magnetic permeability and strength. The magnetic rod 9 is rigidly connected to the lock pin body 10, which can accurately transmit the magnetic force of the electromagnet 8 and drive the lock pin body 10 to move. The lock pin body 10, which is fixedly connected to the magnetic rod 9, is slidably connected through the mounting frame 7. The end of the lock pin body 10 near the smart lock body 2 has a pointed structure, which facilitates smooth insertion into the lock groove 4 to achieve locking. The lock pin body 10 is made of high-strength steel and the surface is treated with anti-rust treatment.

[0023] The side wall of the mounting frame 7 is provided with a sliding opening 11. The locking pin body 10 is slidably connected to and adapted to the sliding opening 11, so that the sliding opening 11 can guide the locking pin body 10, ensuring that the locking pin body 10 can move smoothly along a straight line during the movement, reducing frictional resistance and improving movement accuracy and reliability.

[0024] PCBA board 5 is installed on the lock base 3. PCBA board 5 integrates a microprocessor, a power management module, a communication module, and a drive circuit. The microprocessor uses a high-performance chip, which has powerful data processing capabilities and fast response speed. It is responsible for processing various instructions and control logic. The power management module can convert the input power into a stable voltage suitable for the operation of each component and has overcurrent and overvoltage protection functions. The communication module supports multiple communication protocols, such as Bluetooth, WiFi, RS485, etc., which can realize communication with external devices. The drive circuit precisely controls the current on and off and the direction of the electromagnet 8 according to the instructions of the microprocessor.

[0025] The lock base 3 is equipped with a status display device controlled by the PCBA board 5. The status display device includes multiple sets of tri-color LED beads evenly distributed on the outer edge of the lock base 3 to ensure 360° visibility. The outer edge of the lock base 3 is made of high light transmittance PC material with a light transmittance of ≥90%. Diffusing particles are added inside to make the LED light uniform and soft, without glaring spots. The surface is frosted to enhance the diffuse reflection effect. The PCBA board 5 integrates a driver chip to drive the tri-color LED beads to emit light. In the locked state, the lock base 3 is purple and no additional operation is required. In the unlocked state, that is, there is no smart lock in the lock base 3, it is red. When locking, when the smart lock is accurately pushed into the lock base 3, the lock base 3 will immediately turn green.

[0026] A lock cabinet includes a cabinet body 12. The main body of the cabinet body 12 is made of high-strength metal, which has good physical protection performance and can resist a certain degree of external damage, ensuring the safety of the items inside the cabinet. The cabinet body 12 is provided with a mounting plate 1, and an array of locking and unlocking mechanisms is installed on the mounting plate 1. The lock cabinet is connected to a closing door 13 by hinges on the outside. A fingerprint recognition module and a face recognition module are installed on the closing door 13, and a door lock is installed on the closing door 13. The fingerprint recognition module and the face recognition module can control the door lock to open. The door lock has a built-in control system that supports multiple communication methods, making it easy to integrate with other smart devices to realize functions such as remote control and access control.

[0027] The functional principle of this utility model can be explained through the following operation methods:

[0028] In this invention, when a lock needs to be retrieved, the operator opens the closed door 13 through the fingerprint recognition module or the face recognition module. When the operator issues an unlocking command on the computer, mobile APP, smart card or other authorized device, the communication module receives the command and transmits it to the microprocessor to issue a command. The microprocessor verifies the received command, including user identity recognition, permission judgment, etc. The microprocessor sends an unlocking signal to the drive circuit. The drive circuit applies appropriate voltage and current to the electromagnet 8, energizing the electromagnet 8. According to the principle of electromagnetic induction, the energized electromagnet 8 generates a strong magnetic force, attracting the magnet rod 9. The magnet rod 9 drives the lock pin body 10 to move along the guide rail in the lock seat 3 in the opposite direction to the smart lock body 2. The lock pin body 10 gradually exits from the smart lock body 2. When the lock pin body 10 is completely disengaged from the lock groove 4, the smart lock is unlocked. The corresponding lock seat 3 will flash with a specific color light. It is easy to visually determine which locks are unlocked and can be directly retrieved, greatly improving the operating efficiency.

[0029] When returning the lock, the operator clicks the "Return" command on the computer. The lock seat 3 of the lock cabinet immediately displays red, a color specifically for return operations. This clear indicator helps the user quickly locate the return position, allowing them to directly place the smart lock body 2 inside. The lock seat 3 then immediately turns green. When the user closes the cabinet door, sensors installed on the door (such as microswitches, door magnetic sensors, etc.) detect the door being closed and transmit a signal to the microprocessor. Upon receiving the door-closing signal, the microprocessor sends a locking signal to the drive circuit. The drive circuit changes the current direction of the electromagnet 8, causing the magnetic poles of the electromagnet 8 to reverse, generating a magnetic force in the opposite direction to that used for unlocking. This force pushes the magnetic rod 9, causing the locking / unlocking pin body 10 to move towards the smart lock body 2. The locking pin body 10 precisely inserts into the lock slot 4, at which point the lock seat 3 turns purple again, indicating that the locking / unlocking operation is complete.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
