When the two-way bolt 31 is forced to retract into the lock case assembly 10, the connecting block 3211 drives the first torsion spring 3251 to deform and form an acting force towards the two-way bolt through hole 14, so that the connecting block 3211 can move towards the two-way bolt through hole 14 under the pushing of the acting force.

One end of the second torsion spring 3242 is abutted with the stopper 3212, and the other end is abutted with the first side 17 of the lock housing assembly 10. When the position-limiting member 3212 rotates toward the first side 17, the position-limiting member 3212 presses the second torsion spring 3242 to deform, so that the second torsion spring 3242 can push the position-limiting member 3212 to rotate clockwise when returning.

The safety latch mechanism 70 includes: a safety lock tongue 71, a safety lock positioning block 72, a safety lock locking mechanism 73, a safety lock return spring 74 and a fifth cylinder 75.

The safety lock tongue 71 is connected with the safety lock positioning block 72 and can penetrate through the safety lock tongue through hole 16; one end of the safety lock positioning block 72 is connected with the safety bolt 71, and the other end is connected with the safety bolt return spring 74; the safety bolt locking mechanism 73 is installed in the lock housing assembly 10 and abuts against the safety bolt positioning block 72 and drives the safety bolt positioning block 72 to move towards the safety bolt through hole 16, meanwhile, the safety bolt 71 extends out of the lock housing assembly 10, and the safety bolt positioning block 72 stretches the safety lock return spring 74 to deform the safety bolt return spring 74.

When the fully automatic lock 100 provided in the above embodiment is installed, the lock housing assembly 10 is installed on the door panel, the buckle plate 90 is installed at the door frame, and the buckle plate 90 is disposed corresponding to the side of the lock housing assembly 10 where the main bolt through hole 11 is formed. To facilitate understanding of the operation of the fully automatic lock 100, the following description will be made by taking the locking process of the fully automatic lock 100 as an example:

1. as shown in fig. 11, when the door equipped with the full automatic lock 100 is in an opened state, the two-way bolt 31 and the inclined bolt 80 extend out of the lock case assembly 10, and the main bolt 21 is located inside the lock case assembly 10; specifically, the method comprises the following steps:

the main bolt 21 is positioned in the lock case assembly 10, the first transmission part 561 of the main bolt shifting block 56 abuts against the end part on the right side of the first notch 221, the limiting part 562 abuts against the main bolt positioning block 22, the left side of the first sliding opening 222 abuts against the second cylinder 12, one end of the second shifting piece 57 abuts against the third cylinder 47, and the other end of the second shifting piece 57 does not contact with the second transmission part 563;

the bidirectional bolt 31 extends out of the lock case component 10 completely, one end of the connecting block 3211 is in contact with the side surface of the lock case component 10, the first torsion spring 3241 is in a loose state, the end of the limiting member 3212 is staggered with the end of the connecting block 3211, and the second torsion spring 3242 is in a loose state;

the inclined bolt 80 extends completely out of the lock case assembly 10, the inclined bolt connecting member 322 is far away from the second side surface 18, the pressing portion 3221 abuts against the first abutting portion 3216, and the inclined bolt resetting member 323 is in a relaxed state.

2. When the user closes the door, the two-way bolt 31 and the inclined bolt 80 are pressed by the door frame and retracted into the lock case assembly 10, as shown in fig. 12. The specific process is as follows:

the two-way bolt 31 moves towards the inside of the lock case assembly 10 under the action of the door frame and drives the connecting block 3211 to move towards the second side 18; when the connecting block 3211 moves toward the second side 18, one end of the first torsion spring 3241 moves toward the second side 18 and is converted from a relaxed state to a compressed state, and the connecting block 3211 abuts against the lower edge of the limiting member 3212 and pushes the limiting member 3212 to rotate clockwise; when the limiting member 3212 rotates clockwise, the limiting member drives one end of the second torsion spring 3242 to move toward the second side 18, and the second torsion spring 3242 is converted from a relaxed state to a compressed state; in the final state, the two-way bolt 31 is located inside the lock case assembly 10, the first torsion spring 3241 and the second torsion spring 3242 are in a compressed state, the connecting block 3211 abuts against the first abutting portion 3216 of the position limiting member 3212, and one end of the position limiting member 3212 is located above the connecting block 3211;

the inclined bolt 80 is moved by the door frame toward the inside of the housing assembly 10 and drives the inclined bolt connector 322 toward the second side 18; the pressing portion 3221 will gradually disengage from the first abutting portion 3216; the inclined bolt resetting piece 323 is changed from a relaxed state to a compressed state; in the final state, the inclined bolt 80 is located inside the lock housing assembly 10, the inclined bolt resetting member 323 is in the compressed state, and the pressing portion 3221 is not in contact with the first abutting portion 3216.

3. When the door is fully closed, both the main bolt 21 and the two-way bolt 31 are in the locked state, as shown in fig. 13. The specific process is as follows:

when the door is completely closed, the bidirectional bolt 31 is just opposite to the corresponding hole 91 of the bidirectional bolt, and the external force acting on the bidirectional bolt 31 disappears; the first torsion spring 3421 pushes the connecting block 3211 to move to the left based on the acting force generated by the deformation of the first torsion spring 3421, and drives the two-way bolt 31 to move to the left; when the connecting block 3211 moves to the left side of the lock housing assembly 10, the connecting block 3211 disengages from the position-limiting member 3212; the second torsion spring 3242 drives the limiting member 3212 to rotate counterclockwise based on an acting force generated by the deformation of the second torsion spring 3242, and rotates to a position opposite to the end of the connecting block 3211; the final state of the two-way deadbolt mechanism 30 is: the bidirectional bolt 31 extends out of the lock case assembly 10 completely, the first torsion spring 3241 returns to a relaxed state, the end of the limiting member 3212 is opposite to the connecting block 3211, and the second torsion spring 3242 returns to a relaxed state;

the left side of the inclined bolt 80 is abutted against the buckle plate 90 and still positioned in the lock shell assembly 10, and the inclined bolt resetting piece 323 is still in a compressed state;

when the door is fully closed, the motor 41 is started and drives the driving gear 42 to rotate; the driving gear 42 drives the first transmission gear 53 to rotate clockwise, and further drives the second transmission gear 55 and the main bolt shifting block 56 to rotate anticlockwise; when the main bolt shifting block 56 rotates counterclockwise, the first transmission part 561 rotates counterclockwise and abuts against the left end of the first notch 221, so as to push the main bolt positioning block 22 and the main bolt 21 to move toward the left, so that the main bolt 21 extends out of the lock case assembly 10 completely; the final state of the main bolt mechanism 20 is: the main bolt 21 extends out of the lock case assembly 10 and into the corresponding hole 91 of the main bolt at the buckle plate 90, the first transmission part 561 abuts against the left end of the notch 221, and the right side of the first sliding opening 221 contacts with the second column 12.

It can be understood that the unlocking process of the fully automatic lock 100 in the present embodiment is as follows:

the motor 41 is started and drives the driving gear 42 to rotate, and drives the first transmission gear 53 to rotate anticlockwise, so as to sequentially drive the second transmission gear 55 and the main bolt shifting block 56 to rotate clockwise; the first transmission portion 561 rotates counterclockwise and abuts against the right end of the first notch 221, so as to push the main bolt positioning block 22 and the main bolt 21 to move to the right (i.e. the second side 18); the final state of the main bolt mechanism 20 is: the first transmission part 561 abuts against the right side of the first notch 221, the main bolt 21 retracts into the lock case assembly 10, and the left side of the first sliding opening 222 contacts the second column 10;

in addition, when the second transmission gear 55 rotates clockwise, the first convex part 551 is driven to rotate clockwise and the first shifting piece 60 is pushed to move upwards; the end of the first shifting piece 60 abuts against the transmission abutting portion 3218, and pushes the limiting member 3212 to rotate clockwise, so that the end of the connecting block 3211 and the limiting member 3212 are in a staggered state; when the bidirectional lock tongue 31 is pressed by external force, the connecting block 3211 can be pushed to move towards the right side, and the first torsion spring 3241 is compressed; the limiting member 3212 is pushed by the connecting block 3211 to rotate clockwise, so as to change the second torsion spring 3242 from a relaxed state to a compressed state; when the door panel is completely separated from the door frame, the external force applied to the two-way bolt 31 disappears, the first torsion spring 3241 returns from the compressed state to the relaxed state and drives the two-way bolt positioning block 32 and the two-way bolt 31 to move towards the left side, so that the two-way bolt 31 extends out of the lock case assembly 10;

when the inclined bolt 80 is separated from the door frame, the extrusion force of the door frame disappears, and then the inclined bolt resetting part 323 returns to a loose state from a compressed state, and drives the inclined bolt connecting part 322 and the inclined bolt 80 to move towards the left side, so that the inclined bolt 80 extends out of the lock case assembly 10, and also makes the pressing part 3221 located at the inclined bolt connecting part 322 abut against the first abutting part 3216, and further makes the left end part of the limiting part 3212 staggered with the right end part of the connecting block 3211, so that the bidirectional bolt 31 can retract into the lock case assembly 10 based on external force, and then moves towards the right side based on the connecting block 3211 and pushes the limiting part 3212 to rotate clockwise, thereby realizing the unlocking process of the bidirectional bolt 31.

It can be understood that, as shown in fig. 14, a user located outdoors may also use the ferrule to unlock, which includes the following steps:

the user inserts the ferrule into the first slot 431 and rotates the mechanical shifting block 43 clockwise, so as to drive the mechanical transmission member 44 and the third cylinder 46 to rotate clockwise; when the third cylinder 46 rotates clockwise, the third cylinder abuts against one end of the second poking piece 57 and drives the second poking piece 57 to rotate anticlockwise around the second cylinder 12; when the curved part 571 at the other end of the second shifting piece 57 rotates counterclockwise, the curved part will abut against the second transmission part 563 and drive the second transmission part 563 to rotate clockwise, at this time, the first transmission part 561 also rotates clockwise and drives the main lock tongue positioning block 22 and the main lock tongue 21 to move towards the right side, and finally the main lock tongue 21 retracts into the lock housing assembly 10, so as to realize the unlocking process of the main lock tongue 21;

in addition, when the second transmission part 563 rotates clockwise, the second transmission gear 55 also rotates clockwise to make the first protrusion 551 contact with the first toggle piece 60, so that the first toggle piece 60 pushes the stopper 3212 to move upward, thereby further unlocking the two-way latch 31.

In the fully automatic lock 100 provided in the above embodiment, the driving mechanism 40, the transmission mechanism 50, the first dial piece 60, and the like are all installed inside the lock case assembly 10, and the driving mechanism 40 drives the transmission mechanism 50 to perform transmission so as to enable the main bolt mechanism 20, the two-way bolt mechanism 30, and the like to realize locking or unlocking operations, so that the stability and the safety of the fully automatic lock 100 can be effectively improved.
