Of course, in other embodiments, the unlocking process may be accomplished with the deadbolt drive wheel 32 rotating clockwise with corresponding mating structures.

Referring to fig. 6-9, the motor lock body further includes an oblique tongue assembly, the oblique tongue assembly includes an oblique tongue driving wheel 26, an oblique tongue driving shaft 30, an oblique tongue driving rod 12 and an oblique tongue 13, an outer ring of the oblique tongue driving wheel 26 is engaged with a third driven tooth 33 disposed on the other side of the oblique tongue driving wheel 32, an oblique tongue driving wheel driving groove 28 is disposed on an inner side of the oblique tongue driving wheel 26, an outer end of the oblique tongue driving rod 12 is connected with the oblique tongue 13, an oblique tongue driving rod driving groove 18 is disposed on an inner side of the oblique tongue driving rod 12, and two ends of the oblique tongue driving shaft 30 are disposed on the first lock body shell 100 and the second lock body shell 101 and are matched with the bearing 37 to achieve rotation. The driving shaft projection 29 arranged on the outer ring of the latch driving shaft 30 extends into the latch driving wheel driving groove 28 and the latch driving rod driving groove 18 in the latch driving wheel 26 and the latch driving rod 12, one side of the driving shaft projection 29 is attached to the first inner wall of the latch driving wheel driving groove 28, the other side of the driving shaft projection 29 is attached to the first inner wall of the latch driving rod driving groove 18, the first inner wall of the latch driving rod driving groove 18 is positioned in the latch driving wheel driving groove 28, and the first inner wall of the latch driving rod driving groove 18 extends out of the latch driving wheel driving groove 28 through the first inner wall of the latch driving wheel driving groove 28, so that when the latch is opened, the latch driving wheel 26 drives the latch driving shaft 30 and the latch driving rod 12 to rotate, and the latch driving rod 12 drives the latch to retract; or when the motor lock body is locked by square steel on the inner side of the latch bolt driving shaft 30, the latch bolt driving shaft 30 pushes the latch bolt driving shaft 30 to rotate, and then the latch bolt is driven to extend by the latch bolt driving shaft.

Still taking the structure of fig. 6 as an example, in this case, the left side of the driving shaft projection 29 is engaged with the left inner wall of the latch bolt driving wheel driving groove 28, the right side of the driving shaft projection 29 is engaged with the right inner wall of the latch bolt driving rod driving groove 18, when the latch bolt driving wheel 32 rotates counterclockwise, the latch bolt driving wheel 26 rotates clockwise, the latch bolt driving wheel driving groove 28 on the latch bolt driving wheel 26 pushes the driving shaft projection 29 (i.e., the latch bolt driving shaft 30) to rotate, and the driving shaft projection 29 pushes the latch bolt driving rod 12 to rotate through the latch bolt driving rod driving groove 18, thereby pulling the latch bolt to retract into the housing.

When the latch bolt driving wheel 32 rotates clockwise for locking, the latch bolt driving wheel 26 rotates counterclockwise, at this time, due to the existence of the latch bolt driving wheel driving groove 28, the latch bolt driving shaft 30 cannot rotate along with the latch bolt driving wheel 32 within a certain time, when the locking action is finished, namely, the latch bolt moves to the maximum distance extending out of the shell, the latch bolt driving wheel 32 cannot rotate, the length of the latch bolt driving wheel driving groove 28 can be set according to the situation, so that the driving shaft projection 29 is just positioned at the right side of the latch bolt driving wheel driving groove 28 at this time.

In the preferred embodiment of the present invention, when the motor is used to unlock the lock, when the lock tongues (including the first to third lock tongues) move to the maximum distance, i.e. completely retract into the housing (unlocking action) or extend out of the housing for the maximum distance (locking action), the current of the motor 203 reaches a certain value, e.g. 4.5A-5A, and the motor 203 stops acting. Based on this, the lengths of the first retractor drive slot, the second retractor drive slot, the first tongue drive slot, the second tongue drive slot, and the third tongue drive slot 10 may be set.

The inside of latch bolt drive shaft 30 is provided with square steel hole 31, and the square steel has been pegged graft in the square steel hole 31, when locking through the square steel, still uses the structure of fig. 6 as an example, and square steel anticlockwise rotates, drives latch bolt drive shaft 30 and rotates, and then drives latch bolt drive wheel 26 anticlockwise rotation for latch bolt drive wheel 32 clockwise rotates, thereby realizes that the latch bolt stretches out the shell and locks. In the process, due to the existence of the latch bolt driving rod driving groove 18, the latch bolt driving rod 12 does not rotate along with the latch bolt driving shaft 30, and when the latch bolt extends out of the shell for the maximum distance, the driving shaft lug 29 is just positioned at the left side of the latch bolt driving rod driving groove 18.

It can be seen from the above that when the locking operation is performed by the motor, the key or the square steel, the latch driving lever 12 does not rotate and the latch driving shaft 30 does not rotate when the motor or the key is locked, thereby preventing interference between the locking process and the latch.

In a preferred embodiment of the present invention, referring to fig. 10, the latch bolt assembly further includes an intermediate plate 38, the intermediate plate 38 is located between the latch bolt driving shaft 30 and the latch bolt driving rod 12, and the intermediate plate 38 is provided with an intermediate plate sliding slot 39 matched with the position and size of the driving slot of the latch bolt driving shaft 30, the outer side of the intermediate plate 38 is connected to the lock body housing of the electromechanical lock body through a second spring 40, and one end of the second spring is mounted to the lock body housing of the electromechanical lock body through a positioning pin 41.

When the square steel is used for locking, the second spring 40 is deformed, and after locking is completed, the second spring 40 drags the middle plate 38 to reset in the recovery process to push the latch bolt driving shaft 30 to reset.
