Description

Technical Field

[0001] This utility model mainly relates to the field of security technology, specifically to an electronic lock locking mechanism. Background Technology

[0002] As people's living standards continue to improve, the number of valuables is increasing, and the demand for various safes is also growing. A safe is a lockable cabinet used to store valuables. Currently, there are many types of safes on the market, and they are widely used in offices and homes.

[0003] To ensure security, safes are typically equipped with electronic locking mechanisms to lock them and enhance their safety. Currently, known locking mechanisms generally require the user to input a correct electrical signal through an external device, which powers the internal control circuitry to open the mechanism electronically. After use, closing the safe and then reactivating the locking mechanism via electricity restores the lock. However, existing locking mechanisms are generally simple in design, lacking sufficient security. They cannot effectively prevent forced unlocking by pushing the latch, resulting in poor security performance. Furthermore, if the power drive of the locking mechanism malfunctions, opening the safe becomes extremely difficult, requiring brute force to dismantle the mechanism, making operation very inconvenient. Therefore, it is necessary to propose an improvement to address these technical problems.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides an electronic lock locking mechanism to solve the technical problems existing in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: an electronic lock locking mechanism, comprising a lock cover and a fixed shell, wherein the fixed shell is correspondingly installed on the lock cover; a lock tongue that can be vertically elastically slid and reset is correspondingly provided in the upper part of the fixed shell, and a slot for the upper part of the lock tongue to extend is correspondingly provided at the top of the fixed shell; a mounting bracket is correspondingly installed below the lock tongue in the fixed shell, and a movable latch plate is correspondingly vertically slidably installed on the upper part of the mounting bracket, the top of the movable latch plate correspondingly overlapping the lower part of the lock tongue; an electric drive assembly is correspondingly provided on one side of the top of the mounting bracket, which drives the movable latch plate to move the lock through electric drive. The latch is raised and lowered. When the electric drive component drives the upper part of the latch to extend out of the fixed housing, it is in the locked state, and the electric drive component will automatically stop working. When it is necessary to release the lock, the electric drive component drives the latch to move down until it is fully retracted into the fixed housing, and the electric drive component will automatically stop working. The lower part of the mounting bracket is equipped with a mechanical emergency drive component. Through mechanical manual operation, the movable plate moves the latch down to fully retract into the fixed housing, releasing the lock. The mounting bracket is equipped with an anti-push component to prevent external force from pushing the latch into the fixed housing when it is locked.

[0009] Preferably, the electric drive assembly includes a motor and a toothed plate. The motor is mounted on one side of the upper part of the mounting frame and is connected to the toothed plate via a multi-gear meshing structure. A second mounting groove is provided on the upper part of the mounting frame, and the upper parts of both the toothed plate and the movable retaining plate are slidably mounted in the second mounting groove. The lower part of the toothed plate is inserted into the movable retaining plate; the downward movement of the toothed plate causes the movable retaining plate to move downward, thereby causing the latch to move downward. A compression spring is correspondingly installed between the latch and the mounting frame; after the toothed plate moves upward, the compression spring causes the latch to rise and reset. The second mounting groove on the mounting frame... A first micro switch and a second micro switch are also installed at corresponding positions on one side of the mounting slot. The first micro switch is located above the second micro switch. Two openings are also provided on the corresponding positions on one side of the mounting slot for the springs of the first and second micro switches to extend. When the motor drives the strip tooth plate to rise to the top of the locking tongue and extend out of the fixed housing to lock, it will trigger the first micro switch and the motor will stop working. When it is necessary to release the locking state, the motor drives the strip tooth plate to descend until the locking tongue is fully retracted into the fixed housing. At this time, it will trigger the second micro switch and the motor will stop working.

[0010] Preferably, the multi-gear meshing structure includes a worm, a first double gear, a second double gear, and a third double gear. A first mounting shaft, a second mounting shaft, and a third mounting shaft are respectively mounted at corresponding positions on the mounting bracket. The first, second, and third double gears are respectively mounted on the first, second, and third mounting shafts. The worm is mounted on the output shaft of the motor. One of the first double gears is a worm wheel, which meshes with the worm. The other gear on the first double gear meshes with one gear of the second double gear. The other gear of the second double gear meshes with one gear of the third double gear. The other gear of the third double gear meshes with a toothed rack.

[0011] Preferably, the bottom of the strip toothed plate is provided with a corresponding groove, and the movable plate is provided with a corresponding second protrusion. The second protrusion is engaged in the groove, and the downward movement of the strip toothed plate causes the movable plate to move downward. The lower part of the latch is provided with a corresponding first mounting groove, and one side of the bottom of the first mounting groove is provided with a corresponding engagement platform. One side of the top of the movable plate is provided with a corresponding engagement block. The top of the strip toothed plate and the top of the movable plate are both inserted into the first mounting groove at the lower part of the latch, and the engagement block on the top of the movable plate overlaps the engagement platform of the latch. At the top, the movable plate moves down, causing the locking tongue to move down; a limiting block is correspondingly provided in the upper part of the second mounting groove, and a sliding groove is correspondingly provided on the strip toothed plate to slide vertically with the limiting block; a corresponding slot is provided on the mounting bracket, and a limiting rod is correspondingly installed in the slot. A compression spring is correspondingly sleeved on the outside of the limiting rod. A spring mounting groove is correspondingly provided on one side of the bottom of the locking tongue, and a through hole is correspondingly provided at the top of the spring mounting groove for the limiting rod to slide through. The upper and lower ends of the compression spring are respectively abutted against the bottom of the spring mounting groove and the top of the slot.

[0012] Preferably, a controller is installed inside the fixed housing, and the first micro switch, the second micro switch, and the motor are all electrically connected to the controller.

[0013] Preferably, the anti-push component includes a torsion spring, and the mounting bracket has a torsion spring mounting groove at a corresponding position. A corresponding abutment hole is provided on one side of the torsion spring mounting groove on the mounting bracket. The torsion spring is installed in the torsion spring mounting groove, with one end of the torsion spring inserted into the abutment hole, and the other end of the torsion spring located at the top of the mounting bracket. A corresponding arc groove is provided on the movable plate, with the bottom height of one side of the latch corresponding to the top height of the arc groove. The other end of the torsion spring is located at the bottom of one side of the latch and abuts against the arc groove of the movable plate. When the movable plate moves downward, the other end of the torsion spring twists to avoid the bottom of the latch, allowing the latch to move downward smoothly. When an external force pushes the latch, the other end of the torsion spring blocks the downward movement of the latch at the bottom of the latch.

[0014] Preferably, the mechanical emergency drive assembly includes a rotor and a rotating disk. The rotor is rotatably mounted on the lower part of the mounting frame. A waist-shaped block is correspondingly provided on the inner end face of the rotor, and the rotating disk is correspondingly mounted on the waist-shaped block. An overlapping block is correspondingly provided on one side of the upper part of the rotating disk. A first protrusion is provided at the bottom of the movable plate, and the overlapping block is correspondingly overlapped at the top of the first protrusion. A through lock hole is correspondingly provided in the middle of the rotor, and a keyhole corresponding to the lock hole is provided on the lock cover. Inserting the key into the lock hole and rotating it causes the rotor and rotating disk to rotate, which in turn causes the movable plate to move down and drive the lock tongue down, thus mechanically and manually releasing the locking state.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] This utility model is reasonably designed. By setting up an electric drive component and optimizing its specific structure, the movable plate is driven by electricity to raise and lower the locking tongue. Two microswitches are also included. During operation, when the electric drive component causes the upper part of the locking tongue to extend out of the fixed shell, it triggers the first microswitch, locking the device and automatically stopping the electric drive component. When it is necessary to unlock, the electric drive component causes the locking tongue to move down until it is fully retracted into the fixed shell, triggering the second microswitch and automatically stopping the electric drive component. It is very convenient to use, effectively controlling the motor's shut-off timing according to work needs without manual intervention. It has a high degree of automation, avoiding damage caused by improper human operation leading to the motor not shutting off in time.

[0018] In addition, this utility model also has a mechanical emergency drive component installed in the lower part of the locking mechanism. By optimizing its specific structure, when the motor fails, the key can be manually inserted and turned. The mechanical emergency drive component drives the movable plate to move down, thereby driving the lock tongue to move down until it is fully retracted into the fixed shell. The mechanical manual unlocking state is then achieved, so as to open the safe. This avoids the situation of forcibly disassembling the locking mechanism, realizes mechanical emergency opening, and is more convenient to use.

[0019] Furthermore, this utility model also includes a simple and ingenious anti-push component within the locking mechanism, and optimizes the specific structure of the movable plate and the locking tongue. In use, the top of the torsion spring rests against the arc groove of the movable plate and blocks the bottom of one side of the locking tongue. When the movable plate is moved downwards via an electric drive component or a mechanical emergency drive component, the other end of the torsion spring twists through the arc groove to avoid the bottom of the locking tongue, allowing the locking tongue to move smoothly downwards and release the locking state. Conversely, when an external force pushes the locking tongue, the other end of the torsion spring blocks the bottom of the locking tongue, preventing it from moving downwards and maintaining the locking mechanism in a secure locking state. This effectively prevents external force from forcibly releasing the security lock, greatly improving its security performance. Its overall structural design is ingenious, and its overall use is highly flexible and convenient, making it practical and worthy of promotion.

[0020] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

[0037] See attached document Figure 1-10 This embodiment of an electronic lock locking mechanism includes a lock cover 1 and a fixed shell 2, with the fixed shell 2 correspondingly mounted on the lock cover 1. The upper part of the fixed shell 2 is provided with a vertically elastically sliding lock tongue 3, and the top of the fixed shell 2 is provided with a slot for the upper part of the lock tongue 3 to extend. A mounting bracket 5 is installed below the lock tongue 3 inside the fixed shell 2, and a movable locking plate 17 is vertically slidably mounted on the upper part of the mounting bracket 5, with the top of the movable locking plate 17 overlapping the lower part of the lock tongue 3. A power drive assembly is provided on one side of the top of the mounting bracket 5. Power drive causes the movable locking plate 17 to move the lock tongue 3 up and down. When the power drive assembly causes the upper part of the lock tongue 3 to extend out of the fixed shell 2, it is in a locked state, and the power drive assembly automatically stops working. When it is necessary to release the lock, the power drive assembly causes the lock tongue 3 to move down until it is fully retracted into the fixed shell 2, and the power drive assembly automatically stops working. The lower part of the mounting bracket 5 is equipped with a mechanical emergency drive component. Through manual mechanical operation, the movable latch 17 moves the locking tongue 3 down until it is fully retracted into the fixed housing 2, thus releasing the locking state. The mounting bracket 5 is equipped with an anti-push component to prevent external force from pushing the locking tongue 3 into the fixed housing 2 when it is locked.

[0038] Specifically, the electric drive assembly includes a motor 7 and a toothed plate 6. The motor 7 is mounted on one side of the upper part of the mounting bracket 5, and is connected to the toothed plate 6 via a multi-gear meshing structure. The upper part of the mounting bracket 5 is provided with a second mounting groove 501, in which the upper parts of the toothed plate 6 and the movable retaining plate 17 are slidably mounted. The lower part of the toothed plate 6 is inserted into the movable retaining plate 17. When the toothed plate 6 moves downward, it causes the movable retaining plate 17 to move downward, thereby causing the locking tongue 3 to move downward. A compression spring 19 is installed between the locking tongue 3 and the mounting bracket 5. After the toothed plate 6 moves upward, the compression spring 19 causes the locking tongue 3 to rise and reset. A first micro switch 15 and a second micro switch 16 are also installed on one side of the second mounting groove 501 on the mounting bracket 5. The first micro switch 15 is located above the second micro switch 16. Two openings 506 are provided on one side of the groove wall of the second mounting groove 501 for the springs of the first and second micro switches to extend out. A control circuit board (not shown in the figure) is installed in the lower part of the fixed shell 2. A controller is installed on the control circuit board. The first micro switch 15, the second micro switch 16, and the motor 7 are all electrically connected to the controller. When the motor 7 drives the strip toothed plate 6 to rise to the upper part of the locking tongue 3 and extend out of the fixed shell 2 to lock, it will trigger the first micro switch 15, which will stop the motor 7 from working. When it is necessary to release the locking state, the motor 7 drives the strip toothed plate 6 to descend until the locking tongue 3 is completely retracted into the fixed shell 2. At this time, it will trigger the second micro switch 16, which will stop the motor 7 from working.

[0039] The multi-gear meshing structure includes a worm 8, a first double gear 10, a second double gear 12, and a third double gear 14. A first mounting shaft 9, a second mounting shaft 11, and a third mounting shaft 13 are respectively mounted on the mounting bracket 5 at corresponding positions. The first, second, and third double gears are respectively mounted on the first, second, and third mounting shafts. The worm 8 is mounted on the output shaft of the motor 7. One of the gears on the first double gear 10 is a worm wheel, which meshes with the worm 8. The other gear on the first double gear 10 meshes with one gear of the second double gear 12. The other gear of the second double gear 12 meshes with one gear of the third double gear 14. The other gear of the third double gear 14 meshes with a toothed rack 6, thereby driving the toothed rack 6 to rise and fall.

[0040] The bottom of the strip toothed plate 6 is provided with a corresponding groove 601, and the movable locking plate 17 is provided with a corresponding second protrusion 1704. The second protrusion 1704 is engaged in the groove 601. The downward movement of the strip toothed plate 6 causes the movable locking plate 17 to move downward. The lower part of the latch 3 is provided with a corresponding first mounting groove 301. One side of the bottom of the first mounting groove 301 is provided with a corresponding locking platform 302. One side of the top of the movable locking plate 17 is provided with a corresponding locking block 1701. The top of the strip toothed plate 6 and the top of the movable locking plate 17 are both inserted into the first mounting groove 301 at the lower part of the latch 3, and the locking block 1701 on the top of the movable locking plate 17 overlaps the top of the locking platform 302 of the latch 3. The downward movement of the movable locking plate 17 causes the latch 3 to move downward. The upper part of the second mounting groove 501 is provided with a corresponding limiting block 505, and the strip toothed plate 6 is provided with a corresponding sliding groove 602 that slides vertically with the limiting block 505.

The upper and lower ends of the compression spring 19 are respectively abutted against the bottom of the spring mounting groove 303 and the top of the slot 504. The compression spring 19 allows the latch 3 to rise and reset.

[0041] The anti-push component includes a torsion spring 21. A torsion spring mounting groove 502 is provided at a corresponding position on the mounting bracket 5. An abutment hole 503 is provided on one side of the torsion spring mounting groove 502 on the mounting bracket 5. The torsion spring 21 is installed in the torsion spring mounting groove 502. One end of the torsion spring 21 is inserted into the abutment hole 503, and the other end of the torsion spring 21 is located at the top of the mounting bracket 5. An arc groove 1703 is provided at a corresponding position on the movable plate 17. The bottom height of one side of the latch 3 corresponds to the top height of the arc groove 1703. The other end of the torsion spring 21 is located at the bottom of one side of the latch 3 and abuts against the arc groove 1703 of the movable plate 17. When the movable plate 17 moves down, the other end of the torsion spring 21 will twist to avoid the bottom of the latch 3, allowing the latch 3 to move down smoothly. When an external force pushes the latch 3, the other end of the torsion spring 21 will block the bottom of the latch 3, thus preventing the latch 3 from moving down, thereby improving its security effect.
