[0025] Reference Figure 1 and Figure 2 The slide locking mechanism includes a lock plate 13 and a plate column 14 and a lock column 15 installed on the main slide 3. The lock plate 13 is provided with a fixed window 16, a first dial wheel recess 17 and a lock plate slide groove 18 for accommodating the plate column 14 (the lock plate slide groove 18 is longitudinally arranged on the lock plate 13), and the side of the fixed window 16 is arranged with a card column notch 19. A lock plate spring 20 is installed on the lock plate 13, and the end of the lock plate spring 20 is fixedly connected to the lock housing 1. The main method is to set a pillar on the lock housing, so that the end of the lock plate spring 20 is sleeved on the pillar to achieve the fixed connection between the end of the lock plate spring 20 and the lock housing 1. The subsequent clutch spring 22 is also implemented in a similar manner. Since this method is a commonly used technical method, it will not be described in detail in the specification. When the dial of the lock core 4 is turned, it will push up the bottom of the lock plate 13 first, so that the lock column 15 is separated from the notch 19 of the locking column, and then the dial of the lock core 4 can drive the main slide 3 through the lock core dial notch 6. Similarly, the motor dial blocks 11 symmetrically arranged on both sides of the outer wall of the motor dial wheel 8 will first push the lock plate 13 upward in the first dial notch 17, and then drive the main slide 3 through the motor dial notch 12, so that the main slide 3 can be fixed by the slide locking mechanism whether it is extended or retracted, making the movement of the main slide 3 more stable and reliable, and the entire slide locking mechanism is even more closely installed on the main slide 3, and at the same time associates the lock core 4 and the central dial wheel (connected to the self-separating motor unit through the central dial wheel). Therefore, it is ensured that the space occupied is small while the functions are complete. Figure 2The end of the clamping column notch 19 is provided with a sliding slope 35 so that the locking column 15 can be more flexible when leaving the clamping column notch 19.

[0026] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The self-separating motor unit includes a clutch slide 21, a clutch spring 22 installed on the clutch slide 21, a fixing rivet 23 installed on the clutch slide 21, a motor base plate 24 connected to the rotating shaft of the lock housing 1, a drive motor 25 installed on the motor base plate 24, an output gear 26 installed on the drive motor 25, and a transmission gear 27 connected to the rotating shaft of the lock housing 1, the motor gear 10 and the output gear 26 are both meshed with the transmission gear 27, the oblique tongue transmission mechanism includes a positioning rod 28 installed on the oblique tongue 2, the end of the clutch spring 22 is fixedly connected to the lock housing 1, a limiting convex part 29 is provided on the side of the motor base plate 24, a reset spring 30 is sleeved on the positioning rod 28, and the end of the reset spring 30 is sleeved on the limiting convex part 29, and a for accommodating the motor base plate 24 is provided. The clutch slide groove 31 accommodates the fixed rivet 23, and the clutch slide plate 21 is provided with a longitudinal slide groove 32, a receiving window 33 and a second dial wheel recess 34. The plate column 14 and the lock column 15 are respectively located in the longitudinal slide groove 32 and the receiving window 33. When the dial wheel of the lock cylinder 4 is toggled to the lock plate 13, the clutch slide plate 21 will be pushed up at the same time. After the fixed rivet 23 on the clutch slide plate 21 is displaced in the clutch slide groove 31, the motor base plate 24 is pushed outward in combination with the return spring 30, so that the output gear 26 is separated from the transmission gear 27. When the door handle drives the handle dial wheel 7 (the motor dial wheel 8 is jacketed on the handle dial wheel 7 and will not rotate therewith), the toggle block 49 will also push the clutch slide plate 21 upward in the second dial wheel recess 34, so that the return spring 30 can push the motor base plate 24 outward, so that the output gear 26 is separated from the transmission gear 27. Therefore, referring to Figure 2 The clutch slide plate 21 is similar in structure to the lock plate 13, the main difference being that a shifting tip 54 (see FIG. 1 ) is disposed on the side wall of the second dial wheel recess 34 and is in contact with the shifting block 49. Figure 2 and Figure 4 ), that is, the handle dial wheel 7 firstly releases the self-separating motor unit from the central dial wheel by touching the dial tip 54, and then touches the slide locking mechanism to unlock the main slide 3. The structural design of the self-separating motor unit is exquisite and reasonable, and the clutch accuracy is high, which improves the reliability of the lock body structure motor self-separation.

[0027] Reference Figure 4The clutch slide 31 includes a clutch portion 46 and a longitudinally arranged snap lock portion 47. After the fixing rivet 23 is separated from the snap lock portion 47, the motor base plate 24 can be unlocked, and the motor base plate 24 is pushed by the reset spring 30 to swing along the trajectory of the clutch portion 46. An angle 48 is formed between the snap lock portion 47 and the clutch portion 46, and the range of the angle 48 is 90° to 145°, so that the movement of the motor base plate 24 is smoother and more stable.

[0028] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The oblique tongue transmission mechanism includes an oblique tongue pull plate 36, a lock core pull plate 37 installed on the main slide 3, a reset torsion spring 38 installed on the lock core pull plate 37, and a pull plate rivet 39 and a torsion spring rivet 40 arranged on the main slide 3. The lock core pull plate 37 is provided with a pull plate slide groove 56 for accommodating the pull plate rivet 39. The oblique tongue pull plate 36 is provided with a transmission sheet 41 that is in contact with the oblique tongue paddle 9. The leg of the reset torsion spring 38 is sleeved on the torsion spring rivet 40. The lock core pull plate 37 is provided with a first pull block 42. The upper and lower sides of the lock core pull plate 37 are respectively provided with a motor protrusion 55 and a lock core protrusion 43 touched by the dial wheel of the lock core 4. A second pull block 44 that is in contact with the first pull block 42 is installed on the oblique tongue pull plate 36, and a sliding piece 45 that is sleeved on the positioning rod 28 is integrally formed on the oblique tongue pull plate 36, and the sliding piece is located between the oblique tongue and the reset spring. When the main slide 3 retracts into the lock housing 1, the motor shift block 11 can pull the lock cylinder pull plate 37 through the motor protrusion 55, and then pull back the second pull block 44 through the first pull block 42, so that the oblique tongue pull plate 36 drives the oblique tongue 2 to retract, and the dial wheel of the lock cylinder 4 can also pull the oblique tongue 2 by touching the lock cylinder protrusion 43. The oblique tongue transmission mechanism reduces the internal space occupied by the lock housing while ensuring the association of the lock cylinder and the motor dial wheel, and the transmission is stable and reliable.

[0029] Reference Figure 7The lock core pull plate 37 and the reset torsion spring 38 can be replaced by a lock core pull plate mechanism, and the lock core pull plate mechanism includes a lock core longitudinal push plate 57, a lock core dial plate 58 and a lock core transverse push plate 59. The lock core dial plate 58 is respectively connected to the main slide 3, the lock core longitudinal push plate 57 and the lock core transverse push plate 59 with a rotating shaft, and the three rotating shaft points are triangularly distributed. The lock core longitudinal push plate 57 is provided with a longitudinal push plate groove 60, and the lock core transverse push plate 59 is provided with a transverse push plate groove 61.
