In fact, the slot wall adapted to the working end of the main bolt driver 7 may also be formed in a different slot, or in the mating surface of the protruding block, depending on the specific arrangement of the corresponding working end.

In order to further improve the use safety, the full-automatic lock body can be additionally provided with a back locking function. As shown in the figure, the anti-lock bolt 4 is pivoted to the anti-lock bolt shifting block 41 of the lock body, and the anti-lock bolt shifting block 41 is provided with a ninth working end 411 for driving the anti-lock bolt 4, so that the safety can be further improved.

The working principle of the above preferred embodiment is briefly explained as follows:

firstly, the logic of mechanical unlocking of the true lock pin lock core.

The door shown in fig. 2 is in a closed and locked state, at this time, the detection tongue 1 is pressed and retracted, the main lock tongue 3 is extended, the scissor tongue 2 is extended and locked by the locking block 9, and cannot move along a direction perpendicular to the side edge strip.

When the manual key is unlocked mechanically, the key rotates to drive the lock cylinder shifting piece 61 to rotate towards the direction close to the key shifting piece 8, the first working end 811 of the key shifting piece 8 is closer to the lock cylinder shifting piece 61, the lock cylinder shifting piece 61 drives the first working end 811 of the key shifting piece 8 to rotate around the rotating shaft 84, the second working end 821 of the key shifting piece 8 pushes the eighth working end 73 (arc surface) of the main lock tongue shifting block 7, the main lock tongue shifting block 7 rotates around the rotating center 74 towards the direction far away from the side edge strip, and the sixth working end 71 of the main lock tongue shifting block 7 pushes the first groove wall 31 of the unlocking inner groove of the main lock tongue, so that the main lock tongue 3 slides and contracts along the sliding groove; on the other hand, after the key dial 8 is triggered by the rotation of the key cylinder shifting piece 61, the unlocking shifting block 10 is triggered to rotate, the key cylinder shifting piece 61 pushes the third working end 1011 to rotate towards the direction close to the side edge strip, the fifth working end 1021 pushes the locking block 9 to slide along the sliding groove in the direction far away from the main bolt 3 through the rolling sleeve, the clamping state of the scissor bolt seat assembly is released, namely the scissor bolt 2 can slide along the sliding groove, and the state after mechanical unlocking is completed is shown in fig. 13.

After unlocking is finished, opening the door and turning the key, and pulling the key out of the lock core of the true mortise 6, wherein the key pulling piece 8 does not bear the force of the lock core pulling piece 61 any more, and rotates around the rotating shaft 84 under the action of the deformed second elastic piece 83 to reset to the position state before the key pulling piece 61 rotates; at the same time, the unlocking moving block 10 returns to the position before the rotation of the key moving block under the action of the first elastic element 105, and the locking block is at the unlocking working position. Now the unlocking is completed and the detection tongue 1 is released and no longer pressed when the door is opened, the lock body state is shown in figure 15.

And secondly, electrically driving a locking logic process.

In the door closing process, the scissor tongues 2 and the detection tongues 1 are pressed into the door buckling plate at the same time, after the door closing action is finished, the scissor tongues 2 are popped out and are not pressed any more, and the detection tongues 1 continue to be pressed. The detection tongue 1 is pressed to move in a direction far away from the side edge plate, the second switch contact block 11 at the tail part of the detection tongue 1 triggers the detection tongue switch L2 on the PCB assembly to be disconnected, the push block 12 in the middle part also synchronously moves to avoid clamping the locking block 9, the locking block moves towards the direction close to the main bolt 3 under the action of the elastic force of the fourth elastic piece 92, meanwhile, the first switch contact block 91 triggers the locking block switch L1 to be closed, the scissor bolt seat is clamped to avoid sliding, and the scissor bolt 2 is locked; on the other hand, the PCB assembly controller receives the signal of the state where the detection tongue switch L2 is opened and the locking block switch L1 is closed, and sends a signal to the motor 5 module, the motor starts to rotate and drives the driving gear 51 to start to rotate, the upper locking end protrusion 511 on the driving gear 51 pushes the main bolt 3 shifting block to rotate around the rotating shaft thereof in the direction approaching to the side edge strip, and the seventh working end 72 on the upper side pushes the second groove wall 32 of the unlocking inner groove of the main bolt 3 to make the main bolt 3 slide and extend; when the main bolt 3 is completely extended, namely the main bolt is locked, at the moment, the third switch contact block 33 on the main bolt 3 synchronously triggers the switch shifting block 34 to rotate around the rotating shaft in the direction away from the main bolt, the switch end 5 of the switch shifting block 34 can trigger the main bolt on the PCB assembly to be locked in place, the switch L3 is closed, the motor 5 stops rotating, and the locking is completed. Then the motor 5 rotates reversely to drive the driving gear 51 and the driven gear 52 to rotate, and when the fourth switch contact block 522 on the driven gear 52 contacts the motor reset switch L4 on the PCB assembly, the motor 5 stops rotating. At this time, the driving gear 51 and the driven gear 52 return to the initial positions, and the electric locking process is ended.

In addition, the back latch tongue 4 is independently operated in the door, and the locked state structure of the lock body after the back latch tongue 4 is locked is as shown in fig. 10, the back latch tongue shift block 41 rotates around the rotation center toward the side edge strip, and the ninth working end 411 on the back latch tongue shift block 41 pushes the back latch tongue groove to extend along the sliding groove. It should be appreciated that the anti-lock operation is highest priority.

And thirdly, driving an unlocking logic process by the motor.

After receiving an unlocking command, the motor 5 starts to rotate and drives the driving gear 51, an unlocking end bulge 512 (circular arc shape) on the driving gear 51 pushes the main bolt shifting block 7 to rotate around a rotating shaft thereof towards a direction far away from a side edge strip, a sixth working end 71 on the main bolt shifting block 7 pushes a first groove wall 31 of an unlocking groove on the main bolt 3 to enable the main bolt 3 to contract along a sliding groove, at the moment, a third switch contact block 33 on the main bolt 3 does not trigger the switch shifting block 34 any more, a switch end of the switch shifting block 34 rotates towards a direction close to a lock cylinder under the action of a third elastic piece 35, and a main bolt on the PCB assembly is locked to a position, and the switch L3 is disconnected. On the other hand, the driving gear 51 drives the driven gear 52 to rotate, the unlocking protrusion 521 on the driven gear 52 pushes the fourth working end 1012 of the unlocking shifting block 10 to rotate towards the direction close to the side bar by taking the pivot center 104 as an axis, the fifth working end 1021 pushes the locking block 9 to slide towards the direction far away from the main bolt 3 by a rolling sleeve, when the main bolt 3 contracts, the locking block 9 releases the locking state of the scissors bolt 2, the scissors bolt assembly can slide through the chute, meanwhile, the first switch contact block 91 of the locking block 9 after moving can disconnect the locking block switch L1 on the PCB assembly, the fifth switch contact block 1031 on the unlocking shifting block 10 triggers the unlocking in-place switch to be closed, the task of retracting the main bolt 3 and unlocking the scissors bolt 2 by driving the motor is completed, and the unlocking is completed.
