[0055] When the door is closed, the bevel tongue 62 first hits the door frame and is pushed into the lock body 1 under the pressure of the door frame. In the process of pushing, the trigger tongue 51 also hits the door frame, causing the trigger tongue assembly 5 to be pushed into the lock body 1. The tail of the trigger tongue assembly 5 and the tail of the bevel tongue self-locking assembly 6 are each provided with a control switch 75. The control switch 75 at the tail of the bevel tongue self-locking assembly 6 is turned on only after the bevel tongue 62 is ejected into position. After the door is closed, the bevel tongue 62 of the bevel tongue self-locking assembly 6 is ejected into the door frame hole to the position, and the trigger tongue 51 is pushed into the lock body 1 to the position. At this time, the two switches 75 are turned on (the two switches are connected in series), and a door closing signal is sent to the door lock mainboard. The mainboard controls the motor 72 in the lock body 1 to rotate and drive the gear driving piece 43 to push the square tongue assembly 4 out of the lock body 1 to the position, achieving the function of the square tongue 41 locking the door. The contact surface of the bevel tongue unlocking lever 63 provided on the trigger tongue assembly 5 has left the trigger tongue transmission piece contact end surface 633 provided on the bevel tongue unlocking lever 63. After the bevel tongue 62 is ejected into position, the bevel tongue self-locking assembly is in a self-locking state, and the bevel tongue 62 cannot be turned over, achieving the kinetic energy of the bevel tongue locking the door. The purpose of this setting is that when the trigger tongue 51 is pushed into the lock body 1 to the position, the bevel tongue 62 is ejected from the door frame hole to the position, and the signal of locking the door is sent to the door lock mainboard, ensuring that the square tongue 41 is pushed out to align with the square tongue hole 233 of the door frame when the door is locked. Avoid the failure that the square tongue 41 is not aligned with the hole position when it is pushed out of the lock body 1 during the locking process. At this time, the switch 75 contact of the trigger tongue assembly 5 and the contact end surface 633 of the bevel tongue unlocking lever 63 are in a connected state and send a signal to lock the door. When the door lock circuit mainboard is connected, the motor 72 starts to rotate and drives the square tongue assembly 4 out of the lock body 2. The square tongue 41 is ejected out of the lock body 2 and pushed into the door frame hole to achieve the function of locking the door. When the door is opened, the trigger tongue 51 is ejected out of the lock body 2 to the position, causing the bevel tongue unlocking lever 63 push rod 632 contact end surface to hit and press the self-locking push rod 66 contact surface 665. At this time, the bevel tongue reset seat 67 moves outward to the position. The self-locking push rod 66 front end 663 is separated from the self-locking guide block 68 contact end surface 683. The bevel tongue reset seat 67 is turned over under the bevel tongue turning force, the self-locking guide block 68 is separated from the self-locking contact block 65 contact groove 652, and the bevel tongue 62 is turned over to achieve the unlocking function.

[0056] When the door is opened, the main board will send an opening signal, and when the motor 72 rotates, it will drive the gear adapter piece 74 to drive the gear driving piece 43, and the gear driving piece 43 will engage the square tongue pushing piece 44 to push the square tongue 41 inward to the lock shell 2 to the position, and when the gear adapter piece 74 rotates, the gear adapter piece 74 contact 745 will touch the contact end surface 634 of the latch unlocking piece 63, the latch assembly is unlocked, and the kinetic energy of opening the door is achieved. When the door handle knob rotating wheel 28 rotates, it will touch the contact end surface 449 of the square tongue pushing piece 44, push the square tongue 41 to push inward to the position of the lock shell 2, and at the same time, the self-locking push rod 66 contact end surface 665 of the latch assembly 6 is moved to the position outside the latch reset seat 67, and the latch assembly 6 is unlocked, achieving the function of manual unlocking of the door handle.

[0057] The technical solutions of the present application are not limited, although the present application has been described in detail through the above embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.

The self-locking guide block of the reset seat corresponds to the contact groove of the self-locking contact block, and the contact end face of the front end of the self-locking push rod is matched with the contact end face of the self-locking guide block. The limiting end face of the self-locking push rod is engaged with the limiting stop face of the base box. Then, one end of the reset torsion spring is inserted into the bayonet, and the other end is hung on the pin of the reset box and falls into the guide groove. After that, the cover plate is fastened and the screw is tightened to lock it, thus forming the reset seat. The motor assembly includes a motor, a motor shaft gear, a transition gear, a gear transition plate, and a switch. The motor shaft gear meshes with the transition gear, and the transition gear meshes with the internal teeth of the gear transition plate to drive the square tongue actuating plate to rotate, so that the square tongue is pushed into the lock housing into place. The trigger tongue assembly includes a trigger tongue, a connector, and a reset spring. The trigger tongue corresponds to the trigger tongue hole on the side plate of the lock case. After the connector is sleeved with the reset spring, the tail switch contact of the connector is inserted into the protrusion slot of the lock box for fixation, and the tail switch contact of the connector matches the contact end face of the unlocking lever. The square tongue assembly includes a square tongue, a key drive plate, a gear drive plate, and a square tongue actuating plate. A key drive plate and a torsion spring are provided at the guide groove of the square tongue actuating plate. The gear drive plate and the square tongue actuating plate are stacked under the guide post of the vertical guide groove of the square tongue. The teeth of the gear drive plate mesh with the outer teeth of the gear adapter plate of the motor assembly.

2. The self-control mechanism of a fully automatic lock body as described in claim 1, characterized in that... The unlocking paddle of the tongue assembly is provided with a fixing hole, a push rod, a contact end face of the trigger tongue transmission plate, and a contact end face of the knob block; the self-locking push rod is provided with a reset torsion spring latch, a push rod limiting end face, a contact end face, a front end, a paddle contact end face, and a switch contact surface.

3. The self-control mechanism of a fully automatic lock body as described in claim 2, characterized in that... The latch assembly has a first latch and a second latch, both of which are provided with a rotating hole, a locking position and a contact surface; wherein: the contact surface of the first latch is locked into the contact surface of the latch shell during unlocking and resetting; while the contact surface of the second latch returns to the sliding groove on the bottom surface of the latch shell after resetting.

4. The self-control mechanism of a fully automatic lock body as described in claim 1, characterized in that... The gear adapter plate of the motor assembly is provided with a rotating hole, a directional hole and a contact angle, and is also provided with internal teeth and external teeth for meshing with the teeth of the motor adapter gear and the square tongue drive plate, so that when the motor rotates, the adapter gear drives the square tongue actuating plate of the gear adapter plate to push the square tongue into the lock housing into place.

5. The self-control mechanism of a fully automatic lock body as described in claim 1, characterized in that... The gear drive plate of the square tongue assembly is provided with a rotating hole, a movable groove, and teeth; the square tongue actuating plate is provided with a square tongue guide post, a rotating hole, a torsion spring fixing post hole, a rivet fixing post hole, a guide post hole, a cam insertion port, a torsion spring fixing post, a drive post, and a contact end face.
