[0014] The technical solutions of the embodiments according to the present utility model are explained fully and clearly below with reference to the accompanying drawings. It is understood that the described embodiments represent some of the embodiments of the present utility model, rather than all of them. All other embodiments that could be obtained by a person skilled in the art in this field from the embodiments of the utility model without any inventive step are also within the scope of protection of the utility model.

[0015] It will be on Fig.Reference is made to sections 1 to 4. The present utility model provides a technical solution: a fully automatic electronic armored door lock comprises a lock housing 1 containing a bolt 2, an electronic control module 3, an internal handle control module 4, a mechanical key control module 5, and a motion coupling structure 7. The motion coupling structure 7 is actuated to the bolt 2. By electrically actuating the motion coupling structure 7, the electronic control module 3 pulls the bolt 2 so that it retracts into the lock housing 1, thus completing the unlocking process. The mechanical key control module 5 and the internal handle control module 4 mechanically actuate the motion coupling structure 7 so that the bolt 2 retracts into the lock housing 1, thus completing the unlocking process. The motion coupling structure 7 is connected to a spring return mechanism.After the locking bolt 2 is retracted, it is reset by the spring return structure and extends, thus completing the locking mechanism.

[0016] The motion coupling structure 7 comprises a motion coupling slide plate 71, on the side surface of which a straight toothing 712 is provided. A motion coupling rod 72 is rotatably mounted on the motion coupling slide plate 71, and a camshaft 721 is fixedly mounted on the rod. The motion coupling slide plate 71 is connected to the latch 2, and the lower end of the motion coupling slide plate 71 is integrally connected to a projecting edge 711.

[0017] The mechanical key control module 5 comprises a mechanical locking cylinder 51. The mechanical locking cylinder 51 is connected to a second gear 52, which engages with the spur gear 712. Turning the mechanical locking cylinder 51 with a key rotates the second gear 52, which, by actuating the spur gear 712, moves the motion coupling slide plate 71 downwards to cause the bolt 2 to retract for unlocking.

[0018] The internal handle control module 4 comprises a handle main shaft 41 and a third motion-transmitting actuating plate 43. The handle main shaft 41 is fixedly connected to a second motion-transmitting actuating plate 42, on the side of which a second circular sector-shaped rack 421 is integrally formed. The third motion-transmitting actuating plate 43 is rotatably mounted in the lock housing 1. At one end of the third motion-transmitting actuating plate 43, a third circular sector-shaped rack 431 is integrally formed, which engages with the second circular sector-shaped rack 421. The other end of the third motion-transmitting actuating plate 43 is integrally provided with a projection 432, which rests against and is connected to the projecting edge 711.

[0019] By rotating the handle main shaft 41 under the drive of an internal handle, the second motion-transmitting actuating plate 42 is set into rotation. The third motion-transmitting actuating plate 43 is rotated counterclockwise by means of the engagement relationship between the second circular sector-shaped rack 421 and the third circular sector-shaped rack 431. Through the interaction of the projection 432 with the projecting edge 711, the motion-coupling sliding plate 71 is moved downwards to cause the retraction of the latch 2 for unlocking.

[0020] The electronic control module 3 comprises a servo motor 31 and a first motion-transmitting actuating plate 35. The servo motor 31 is fixedly mounted in the lock housing 1. A driving bevel gear 32 is fixedly attached to an output shaft of the servo motor 31 and is drivenly connected to a gear bevel gear 33. A gear is stacked above the gear bevel gear 33 and meshes with and is connected to a first gear 34. The first motion-transmitting actuating plate 35 is rotatably mounted in the lock housing 1. A first circular sector-shaped rack 352 is integrally formed at one end of the first motion-transmitting actuating plate 35, and the other end is designed as an actuating head 351. The first circular sector-shaped rack 352 meshes with the first gear 34, and the actuating head 351 rests against and is connected to the camshaft 721.

[0021] The servomotor 31 drives the first motion-transmitting actuating plate 35 via the driving bevel gear 32, the gear bevel gear 33, and the first gear 34, causing it to rotate. This rotates the actuating head 351 counterclockwise, thereby actuating and downward moving the camshaft 721. The camshaft 721, via the motion coupling rod 72, pulls the motion coupling sliding plate 71 downward, thus retracting the latch 2 for unlocking. Operating principle: Three unlocking options are available: electronic, manual from the inside, and mechanical with a key. The latch 2 is driven uniformly via the motion coupling structure 7. The specific operating sequence is as follows: Electronic unlocking: The servo motor 31 is started and drives the driving bevel gear 32, which sets the transmission bevel gear 33 in rotation. The motion is transmitted via the first transmission gear 34 to the first motion-transmitting actuating plate 35, causing it to rotate counterclockwise. The actuating head 351 of the first motion-transmitting actuating plate 35 pushes the camshaft 721 on the motion coupling rod 72 such that it moves downwards. The motion coupling rod 72 sets the motion coupling sliding plate 71 in motion downwards, causing the bolt 2 to engage in the lock housing 1 and completing the unlocking process. Unlocking via the inside handle: Turning the inside handle sets the handle main shaft 41 and the second motion-transmitting actuating plate 42 into rotation. The engagement of the second circular sector-shaped rack 421 with the third circular sector-shaped rack 431 rotates the third motion-transmitting actuating plate 43 counterclockwise. The projection 432 at the end of the third motion-transmitting actuating plate 43 pushes the projecting edge 711 of the motion-coupling slide plate 71, causing the motion-coupling slide plate 71 to move downwards, thereby engaging the latch 2. Mechanical unlocking via key: Turning the mechanical locking cylinder 51 with a key drives the second gear 52 to rotate. This gear engages with the straight teeth 712 on the motion coupling slide plate 71 and actuates the motion coupling slide plate 71 in such a way that it is moved downwards, thereby retracting the bolt 2. Automatic locking: After unlocking, the motion coupling sliding plate 71 is returned upwards to its starting position by the action of the spring return structure. This pushes the bolt 2 so that it extends from the lock housing 1, thus completing the locking action. Content not explained in detail in this description is part of the state of the art, which is generally known to experts in this field.

[0022] In summary, a fully automatic electronic armored door lock is disclosed. It comprises a lock housing containing a bolt, an electronic control module, an inside handle control module, a mechanical key control module, and a motion coupling structure. The motion coupling structure is drive-connected to the bolt, with the electronic control module electrically driving the motion coupling structure, and the mechanical key control module and the inside handle control module mechanically driving the motion coupling structure. The motion coupling structure is connected to a spring return structure. The present utility model provides three independent unlocking options: electronic, manual from the inside, and mechanical via key. This ensures reliable unlocking even in the event of a power failure, electronic malfunctions, or other adverse conditions.
