[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a fully automatic electronic armored lock, comprising: a lock shell 1, a bolt 2, an electronic control module 3, an inner handle control module 4, a key mechanical control module 5, and a linkage structure 7, wherein the linkage structure 7 is connected to the bolt 2, the electronic control module 3 electrically drives the linkage structure 7 to pull the bolt 2 inward into the lock shell 1 to complete unlocking, the key mechanical control module 5 and the inner handle control module 4 mechanically drive the linkage structure 7 to pull the bolt 2 inward into the lock shell 1 to complete unlocking, and the linkage structure 7 is connected to a spring reset structure, which resets and extends the bolt 2 after it retracts, thus completing locking.

[0016] The linkage structure 7 includes a linkage slide plate 71, a straight tooth 712 is provided on the side of the linkage slide plate 71, a linkage rod 72 is rotatably mounted on the linkage slide plate 71, a convex shaft 721 is fixedly mounted on the linkage rod 72, the linkage slide plate 71 is connected to the lock tongue 2, and the lower end of the linkage slide plate 71 is integrally connected to the convex edge 711. The key mechanical control module 5 includes a mechanical lock cylinder 51, which is connected to a second transmission gear 52. The second transmission gear 52 meshes with a spur gear 712. By rotating the key, the mechanical lock cylinder 51 drives the second transmission gear 52 to rotate, which in turn drives the linkage slide 71 to move downward by moving the spur gear 712, thereby realizing the inward retraction of the lock tongue 2 for unlocking.

[0017] The inner handle control module 4 includes a handle spindle 41 and a third transmission paddle 43. The handle spindle 41 is fixedly connected to the second transmission paddle 42. The second transmission paddle 42 has a second sector rack 421 integrally provided on its side. The third transmission paddle 43 is rotatably installed in the lock housing 1. The end of the third transmission paddle 43 has a third sector rack 431 integrally provided. The third sector rack 431 meshes with the second sector rack 421. The other end of the third transmission paddle 43 has a protrusion 432 integrally provided. The protrusion 432 abuts against the protruding edge 711. The inner handle drives the main shaft 41 of the handle to rotate, which in turn drives the second transmission paddle 42 to rotate. By utilizing the meshing relationship between the second sector rack 421 and the third sector rack 431, the third transmission paddle 43 is driven to rotate counterclockwise. Through the cooperation between the protrusion 432 and the protrusion edge 711, the linkage slide 71 is driven to move downward, thereby realizing the inward retraction of the locking tongue 2 for unlocking.

[0018] The electronic control module 3 includes a servo motor 31 and a first transmission paddle 35. The servo motor 31 is fixedly installed inside the lock housing 1. A drive bevel gear 32 is fixedly installed on the output shaft of the servo motor 31. The drive bevel gear 32 is connected to a transmission bevel gear 33. A gear is stacked on the transmission bevel gear 33, which meshes with a first transmission gear 34. The first transmission paddle 35 is rotatably installed inside the lock housing 1. One end of the first transmission paddle 35 is integrally provided with a first sector rack 352, and the other end is a paddle head 351. The first sector rack 352 meshes with the first transmission gear 34, and the paddle head 351 abuts against the cam shaft 721. The servo motor 31 drives the first transmission paddle 35 to rotate by driving the bevel gear 32, the transmission bevel gear 33 and the first transmission gear 34, which in turn drives the paddle head 351 to rotate counterclockwise, causing the cam shaft 721 to move downward. The cam shaft 721 pulls the linkage slide 71 downward through the linkage rod 72, thereby realizing the inward retraction of the lock tongue 2 for unlocking.

[0019] Working principle: It has three unlocking methods: electronic, internal manual, and key mechanical, all of which are driven by the linkage structure 7 to move the bolt 2. The specific working process is as follows: Electronic unlocking: The servo motor 31 starts, driving the bevel gear 32 to rotate the transmission bevel gear 33. The rotation is transmitted to the first transmission paddle 35 via the first transmission gear 34, causing it to rotate counterclockwise. The paddle head 351 of the first transmission paddle 35 pushes the convex shaft 721 on the linkage rod 72 to move downward. The linkage rod 72 drives the linkage slide 71 to move downward, and the lock tongue 2 retracts into the lock case 1, completing the unlocking.

[0020] Unlocking with the inner handle: Rotating the inner handle drives the handle spindle 41 and the second transmission paddle 42 to rotate. Through the meshing of the second sector rack 421 and the third sector rack 431, the third transmission paddle 43 rotates counterclockwise. The protrusion 432 at the end of the third transmission paddle 43 pushes the protruding edge 711 of the linkage slide 71, causing the linkage slide 71 to move down and the locking tongue 2 to retract.

[0021] Mechanical unlocking with key: The key rotates the mechanical lock cylinder 51, which drives the second transmission gear 52 to rotate. The gear meshes with the spur tooth 712 on the linkage slide 71, causing the linkage slide 71 to move down and retract the lock tongue 2.

[0022] Automatic locking: After unlocking, the linkage slide 71 returns to its original position under the action of the spring reset structure, pushing the lock tongue 2 out of the lock case 1 to complete the locking.

[0023] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
