[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions.

[0018] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," and "connect" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection; direct connection, connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0019] The following description of the embodiments of the present invention is provided in conjunction with the accompanying drawings to further describe the specific embodiments of the present invention so that the technical solutions and beneficial effects of the present invention are more clearly understood. The following description of the embodiments with reference to the accompanying drawings is for illustrative purposes only and is intended to explain the present invention, but is not to be construed as limiting the present invention.

[0020] The preferred embodiment provided by the present invention is as follows: Figures 1 to 3As shown, a fully automatic door lock includes a lock housing 1, in which a motor assembly 2, a lock cylinder 3, a drive shaft core 4, and a rotating shaft core 5 are arranged. The lock housing 1 is equipped with a core sleeve 31, which has a cavity. The lock cylinder 3 is mounted on the core sleeve 31 and can rotate therein. The motor assembly 2 is connected to the drive shaft core 4, which is plugged into the rotating shaft core 5. The lock cylinder 3 is mounted on the core sleeve 31 and has a core rod 32. The core rod 32 passes through the rotating shaft core 5 and is connected to the drive shaft core 4. The drive shaft core 4 is driven to rotate by the motor assembly 2, and the rotating drive shaft core 4 causes the rotating shaft core 5 and the lock cylinder 3 to achieve linkage.

[0021] The motor assembly 2 includes a motor 21, a speed gear set 22 and a driving gear 23. The motor 21 is connected to the driving gear 23 through the speed gear set 22. The speed gear set 22 is composed of several gears connected to each other, and the diameters of the gears are combined and connected according to needs.

[0022] The drive shaft core 4 has a first through hole 41. The drive shaft core 4 passes through the first through hole 41 and rotates in the first through hole 41. Both the drive shaft core 4 and the first through hole 41 extend a protrusion 42. The protrusions 42 of the drive shaft core 4 and the first through hole 41 rotate and abut against each other to enable the drive shaft core 4 to generate linkage with the drive gear 23.

[0023] The drive shaft core 4 has a coupling post 43, and the rotating shaft core 5 has a second through-hole 51. The cross-sectional shapes of the coupling post 43 and the second through-hole 51 match, and the coupling post 43 is inserted into the second through-hole 51 to achieve linkage between the drive shaft core 4 and the rotating shaft core 5. In this embodiment, the cross-sectional shapes of the coupling post 43 and the second through-hole 51 are both square. The coupling post 43 has an insertion cavity 44, and the core rod 32 is inserted into the insertion cavity 44 to achieve linkage between the lock cylinder 3 and the drive shaft core 4.

[0024] The rotating shaft core 5 is connected to the lock tongue push rod 6. The rotating shaft core 5 is provided with a first transmission tooth 52, and the lock tongue push rod 6 is provided with a second transmission tooth 62. The first transmission tooth 52 is engaged with the second transmission tooth 62 to connect the rotating shaft core 5 and the lock tongue push rod 6.

[0025] The lock housing 1 is provided with a fingerprint element to drive the motor 21 to rotate. In this structure, the method of driving the lock tongue to open by driving the handle is eliminated, and the lock tongue is driven to open by the lock core 3 and the motor 21. When the lock is unlocked by the motor 21, the motor 21 rotates the drive shaft core 4 through the speed change gear set 22. The connecting column 43 of the drive shaft core 4 is connected to the second through hole 51 of the rotating shaft core 5. The rotating drive shaft core 4 drives the rotating shaft core 5 to rotate, and the rotation of the shaft core can push the lock tongue push rod 6 to move. The unlocking method of the lock core 3 adopts the existing lock core 3 structure. Inserting the correct key can drive the lock core 3 to rotate. Inserting the wrong key will only cause the lock core 3 to rotate idly. When the motor 21 unlocks, the keyhole does not have a key inserted and the lock core 3 is in an idling state in the core sleeve 31. Since the lock core 3 is connected to the connecting column 43 of the drive shaft core 4 through the core rod 32, the drive shaft core 4 will drive the lock core 3 to rotate idly, which does not affect the unlocking. When the key is used to unlock the lock, the lock core 3 rotates the drive shaft core 4 through the core rod 32, and the drive shaft core 4 drives the rotating shaft core 5 connected thereto to rotate, thereby unlocking the lock.

[0026] In the description of the specification, reference to the terms "one embodiment," "preferably," "example," "specific example," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. The schematic expressions of the above terms in this specification do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any appropriate manner in any one or more embodiments or examples.

[0027] Through the description of the above structure and principle, technical personnel in the relevant technical field should understand that the present invention is not limited to the above specific implementation methods, and improvements and substitutions based on the present invention using the well-known technology in the field all fall within the scope of protection of the present invention and should be defined by the claims.
