Description

Technical Field

[0001] This utility model relates to the field of safe lock technology, specifically to a fully automatic electromechanical separation lock assembly for safes. Background Technology

[0002] Existing safe door lock structures typically employ a single-directional or limited-directional bolt design for locking and unlocking, which may result in insufficient protection and inability to effectively resist attacks from multiple angles. Traditional door lock structures usually rely solely on simple mechanical bolts for locking, making them vulnerable to damage or bypassing. Therefore, to enhance the protective capabilities of safes, designers need a door lock structure that can provide reliable locking from multiple directions.

[0003] Secondly, existing electric drive systems mostly rely on a single electric or mechanical method for unlocking. If either method malfunctions, it often affects the normal operation of the lock. This means that electric unlocking systems may fail to provide reliable unlocking functionality when encountering power or battery problems. Meanwhile, the manual operation of mechanical key systems may also suffer from problems such as jamming and awkward operation due to traditional designs. Therefore, lock design must address the compatibility of electric and mechanical unlocking methods as well as the smoothness of manual unlocking.

[0004] Furthermore, existing door lock structures have complex transmission systems during unlocking, lacking sufficient compensation and adjustment mechanisms. This can lead to instability during bolt movement, affecting the bolt's precise movement. Traditional designs often neglect the precise adjustment requirements of the bolt under different operating conditions, potentially resulting in reduced instability and reliability of the lock.

[0005] Therefore, the problems in the background technology mainly focus on the multi-directional locking of the bolt, the compatibility and stability of the drive system, and the precise control of the bolt transmission process. These deficiencies have prompted the innovation of this new door lock structure, which proposes to optimize the safety and reliability of the door lock through technical means such as multi-directional bolts, precise gear transmission, elastic support and stroke compensation. Utility Model Content

[0006] This utility model provides a fully automatic electromechanical separation lock assembly for safes.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] The fully automatic electromechanical lock assembly for safes includes a door panel for mounting the lock structure, a keyhole pre-set on the door panel, and mounting holes for the electronic lock. The lock structure includes a top bolt, a bottom bolt, a main bolt, and a drive structure for driving the top bolt, bottom bolt, and main bolt. The top bolt, bottom bolt, and main bolt face three directions respectively and are pushed by the same connecting plate. The drive structure engages with a rack on the connecting plate to drive the connecting plate to move horizontally, thereby driving the top bolt, bottom bolt, and main bolt to move.

[0009] In a specific embodiment, the connecting plate includes a linkage rack and a sliding post disposed opposite to the back plate; the end of the back plate is connected to a main bolt and is provided with a horizontal sliding hole and a vertical sliding hole, the horizontal sliding hole being disposed opposite to the sliding post, and the sliding post moving along the horizontal sliding hole.

[0010] In one specific embodiment, it also includes a T-shaped plate, one end of which is connected to a top bolt and the other end to a bottom bolt. A hole is provided in the middle of the T-shaped plate for installing and connecting a sliding column. When the sliding column moves along the horizontal sliding hole, it drives the T-shaped plate to move. A limiting post is provided at the other end of the T-shaped plate, and the limiting post moves up and down along the vertical sliding hole.

[0011] In a specific embodiment, the driving structure includes a cover, a drive motor, a first gear set, a second gear set, a third gear set, and a lock cylinder; the output end of the drive motor is a worm gear structure, which drives the first gear set to rotate, the pinion of the first gear set meshes with the large gear of the second gear set, the pinion of the second gear set drives the large gear of the third gear set to rotate, and the pinion of the third gear set meshes with a rack.

[0012] In a specific embodiment, the pinion of the third gear set is fitted with an elastic element. When the drive motor drives the gear set, the third gear set is supported by the elastic element and meshes with the second gear set and the first gear set to achieve electric unlocking. When a mechanical key is used, the mechanical key is inserted into the lock cylinder and the third gear set is pressed down. The large gear of the third gear set disengages from the pinion of the second gear set, and the third gear is manually driven to rotate, thereby unlocking the lock.

[0013] In one specific embodiment, a stroke compensation component is also included. The stroke compensation component is a rigid spring, one end of which is connected to the back plate and the other end is connected to one end of the connecting plate. The direction of the force on the rigid spring is the direction of movement of the main bolt.

[0014] This utility model comprises multiple components: a door panel, a keyhole, an electronic lock mounting hole, and a drive structure. By incorporating a top bolt, a bottom bolt, and a main bolt, along with a sophisticated drive structure, the door lock can simultaneously lock and unlock in multiple directions, enhancing its protective performance. The drive structure, through engagement with a rack and pinion on the connecting plate, precisely controls the movement of the top bolt, bottom bolt, and main bolt, ensuring the reliability and accuracy of the door lock. Furthermore, the linkage rack and pinion design of the connecting plate and the sliding post effectively realize the horizontal and vertical movement of the bolts, further improving the stability of the lock. The design of the T-shaped plate and the limiting post ensures that each bolt is undisturbed during movement, avoiding the risk of system malfunction.

[0015] The drive system employs a complex transmission structure comprising a drive motor, gear set, and lock cylinder. Through the worm gear mechanism and the step-by-step transmission of the gear set, the horizontal movement of the bolt is precisely driven, thereby opening and closing the door lock. Notably, the external elastic element of the third gear set ensures smoothness and reliability during electric unlocking, while also allowing manual unlocking via mechanical key operation, guaranteeing emergency use in case of battery or power failure. The addition of a travel compensation component further optimizes the smoothness and stability of the bolt movement, ensuring precise operation under various conditions. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The following description, in conjunction with the accompanying drawings, provides a specific embodiment of the "fully automatic electromechanical separation lock assembly for safes" of this utility model, but the utility model is not limited to this embodiment.

[0025] Example 1

[0026] See Figures 1-6 As shown, the fully automatic electromechanical separation lock assembly for safes provided by the present invention includes a door panel 1 for installing a door lock, a keyhole 2, an electronic lock mounting hole 3, and a door lock drive structure. The door panel 1 is used to install a top bolt 4, a bottom bolt 5, a main bolt 6, and a drive structure 7. The door panel 1 has a pre-set keyhole 2 for installing a mechanical lock cylinder and an electronic lock mounting hole 3 for installing an electronic lock panel.

[0027] As shown in the figure, the door lock structure includes a top bolt 4, a bottom bolt 5, a main bolt 6, and a drive structure 7 for actuating these bolts. The top bolt 4, bottom bolt 5, and main bolt 6 face three different directions and are driven by the same connecting plate 8. Specifically, the top bolt 4 faces the top of the door lock, the bottom bolt 5 faces the bottom, and the main bolt 6 faces one side. This multi-directional bolt design enhances the safe's protective performance, effectively preventing attacks or damage from multiple angles, and the unified drive ensures stable opening and closing.

[0028] The drive structure 7 engages with the rack 9 on the connecting plate 8, causing the connecting plate 8 to move horizontally. The horizontal movement of the connecting plate 8 then drives the movement of the top bolt 4, the bottom bolt 5, and the main bolt 6, thereby realizing the movement and locking functions of multiple bolts in different directions.

[0029] In one embodiment, the connecting plate 8 includes a linkage rack 9 and a sliding post 11 disposed opposite to the back plate 10. The back plate 10 is located inside the door panel 1. A main bolt 6 is connected to the end of the back plate 10, and a horizontal sliding hole 12 and a vertical sliding hole 13 are provided on the back plate 10 to support the sliding and positioning of the connecting plate 8. The horizontal sliding hole 12 is disposed opposite to the sliding post 11, and the sliding post 11 can move along the horizontal sliding hole 12. The movement of the sliding post causes the main bolt 6 to slide in the horizontal direction.

[0030] In this embodiment, a T-shaped plate 14 is also included. The design of the T-shaped plate 14 allows it to connect both the top bolt 4 and the bottom bolt 5 simultaneously, forming an "I"-shaped structure. A hole 15 is provided in the middle of the T-shaped plate 14 for mounting and connecting the sliding post 11. The movement of the sliding post 11 in the horizontal sliding hole 12 drives the T-shaped plate 14 to move synchronously, ensuring that the top bolt 4 and the bottom bolt 5 can move in parallel, thereby achieving a more stable locking effect.

[0031] A limiting post 16 is provided at the other end of the T-shaped plate 14. The limiting post 16 can move up and down along the vertical sliding hole 13, which can prevent excessive displacement of the T-shaped plate 14 and the connecting plate 8. The up and down movement of the limiting post 16 limits the maximum range of motion of the bolt, ensuring that the movement of the bolt is not disturbed, thereby avoiding system failure.

[0032] In a specific implementation of the drive structure 7, the drive structure includes a cover 17, a drive motor 18, a first gear set 19, a second gear set 20, a third gear set 21, and a lock cylinder 22. The output end of the drive motor 18 is a worm gear structure 23, which drives the first gear set 19 to rotate. The pinion of the first gear set 19 meshes with the large gear of the second gear set 20, and the pinion of the second gear set 20 drives the large gear of the third gear set 21 to rotate. The pinion of the third gear set 21 meshes with the rack 9 on the connecting plate 8, thereby causing the connecting plate 8 to move horizontally, which in turn drives the movement of the top bolt 4, the bottom bolt 5, and the main bolt 6.

[0033] In this embodiment, the pinion of the third gear set 21 is fitted with an elastic element 24. The elastic element 24 can be a spring or other elastic component, and its main function is to provide support for the third gear set 21 when driven by the drive motor 18. The design of the elastic element 24 ensures the smoothness and reliability of the electric unlocking process.

[0034] During manual unlocking, after the mechanical key is inserted into the lock cylinder 22, the user can rotate the mechanical key to press down on the third gear set 21, disengaging it from the pinion of the second gear set 20. Manually rotating the third gear set 21 disengages its large gear from the pinion of the second gear set 20, allowing the user to manually drive the third gear set 21 and thus unlock the lock.

[0035] Furthermore, this embodiment also includes a travel compensation component 25, which is mainly composed of a rigid spring. The two ends of the rigid spring 25 are connected to the back plate 10 and the connecting plate 8, respectively. The rigid spring 25 provides additional compensation force during the movement of the main bolt 6, thereby optimizing the bolt's movement and ensuring smooth and precise movement. This design effectively prevents instability in the bolt's movement due to external impacts or improper operation, further improving the reliability of the door lock.

[0036] In summary, the safe door lock structure provided by this invention achieves higher security, stability, and reliability through multi-directional locking design, a precise drive system, elastic support, and travel compensation. This design not only enhances the lock's protective performance but also optimizes the compatibility of electric and manual unlocking, allowing it to continue operating normally even in the event of battery or power failure, thus providing users with a more reliable safe protection solution.
