[0022] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 6 As shown, a motor drive mechanism of a smart lock includes an outer panel 1, an inner panel 2 and a lock core 3 arranged between the outer panel 1 and the inner panel 2. The outer panel 1 is provided with a password disk 11, a lock button 12 and a doorbell button 13.

[0024] Inside the inner panel 2, from top to bottom, are a battery compartment 21 and a motor 22. A knob 23 is located on the outside of the inner panel 2, engaging the motor 22 via a drive shaft 24. A control button 25 is located on the inside of the inner panel 2, below the knob 23. The control button 25 includes an unlock button and a lock button. The battery compartment 21 houses batteries that power the motor 22. A control mechanism is also located within the inner panel 2. The combination dial 11, the lock button 12, and the control button 25 are connected to the control mechanism and the motor 22 in sequence, enabling the motor 22 to be controlled by the combination dial 11, the lock button 12, and the control button 25.

[0025] The lock cylinder 3 includes a lock shell 31 and a first connecting shaft 34 arranged on the lock shell 31. A lock hole 311 is provided on the lock shell 31. A mounting groove 312 extending downward from the lock hole 311 is provided on the top of the lock shell 31. A thumb wheel 37 is provided in the mounting groove 312. The thumb wheel 37 includes a third matching hole 371 and a recess 372 arranged on the side wall of the third matching hole 371. The first drive head 32 and the second drive head 38 are arranged in sequence from left to right in the thumb wheel 37. The axis of the first drive head 32 is provided with a first matching hole 321, the outer side of the first drive head 32 is provided with a first protrusion 322, the axis of the second drive head 38 is provided with a second matching hole 381, the side wall of the second drive head 38 is provided with a second protrusion 382, ​​and the end of the second drive head 38 is provided with a matching groove 383. The outer sides of the first drive head 32 and the second drive head 38 are matched with the third matching hole 371. The recess 372 cooperates with the first protrusion 322 or the second protrusion 382 , so that the first drive head 32 and the second drive head 38 can drive the dial wheel 37 to rotate and thus control the extension or retraction of the lock tongue.

[0026] The motor 22 is provided with a fourth matching hole 221 that matches the driving shaft 24 . A driving disk 222 is provided inside the fourth matching hole 221 . When the motor 22 is working, the driving shaft 24 is driven to rotate via the driving disk 222 .

[0027] A lock core 33 is disposed within the lock hole 311 on the side closest to the outer panel 1. A key slot is provided within the lock core 33. A first connecting shaft 34, a spring 35, and a telescopic head 36 are sequentially disposed within the lock hole 311 on the side closest to the inner panel 2. The spring 35 is sleeved on the telescopic head 36. The telescopic head 36 includes a second connecting shaft 361 that engages with the first and second mating holes 321, 381. An end cap 362 is provided at the end of the second connecting shaft 361.

[0028] The first connecting shaft 34 includes a square handle 341 and a circular hollow cavity 342 therein. The square handle 341 is cooperatively connected to the driving shaft 24 .

[0029] The spring 35 is disposed in the circular cavity 342 and one end of the spring 35 abuts against the side wall of the circular cavity 342 , while the other end of the spring 35 abuts against the side wall of the first drive head 32 and forces the first drive head 32 and the second drive head 38 to move away from the circular cavity 342 .

[0030] When the door is locked, the spring 35 is in an extended state. The spring 35 forces the telescopic head 36 to extend toward the lock core 33. The telescopic head 36 forces the first drive head 32 and the second drive head 38 to move toward the lock core 33. At this time, the first protrusion 322 of the first drive head 32 cooperates with the recess 372 of the thumbwheel 37. When the motor 22 is turned on, the motor 22 drives the first drive head 32 to rotate, which can drive the thumbwheel 37 to rotate, so that the thumbwheel 37 can drive the lock tongue to retract or extend.

[0031] When the key is used to unlock the door from outside, the key is inserted into the lock core 33 and cooperates with the cooperating groove 383 of the second drive head 38. When the key is pushed inward, the key forces the telescopic head 36 to retract inward, the telescopic head 36 compresses the spring 35 and the telescopic head 36 forces the first drive head 32 and the second drive head 38 to move inward. At this time, the first drive head 32 is separated from the thumbwheel 37, and the second drive head 38 cooperates with the thumbwheel 37. The second protrusion 382 of the second drive head 38 cooperates with the recess 372 of the thumbwheel 37, so that by turning the key, the thumbwheel 37 can be driven to rotate through the second drive head 38, so that the thumbwheel 37 can drive the lock tongue to retract or extend.

[0032] When indoors, you can also directly press the unlock button on the control button 25 to open the door or the lock button to close the door. Once the battery is low, you can also directly rotate the drive shaft 24 by turning the knob 23 to open the door. When going out, you can quickly lock the door by closing the door and pressing the lock button 12.

[0033] The motor drive mechanism of the smart lock of the present invention is connected to the lock core by setting a motor 22. The button controls the motor 22 to drive the dial wheel 37 to rotate to control the retraction or extension of the lock tongue. The smart lock can achieve one-button unlocking and one-button locking, with a simple structure and easy use.

[0034] Finally, it should be noted that the above embodiments only illustrate the technical solutions of the present invention and do not limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
