The working principle is as follows:

1. Motor unlocking

Referring to fig. 2, 11 and 12, the motor assembly 6 drives the driving gear 602 to rotate clockwise according to the read fingerprint, password and other unlocking signals, drives the large gear 5 to rotate anticlockwise, the small gear 504 on the large gear 5 drives the main tongue assembly 4 to move backwards through meshing with the main rack 407 on the main tongue assembly 4, so that the lock bolt 401 retracts into the lock shell, meanwhile, the limiting block 505 on the large gear 5 rotates along with the large gear 5 in the opening groove 411 from the locking gear 408 to the unlocking gear 409 when locking, limits the main tongue assembly 4, then the large gear 5 continues to rotate in the yielding space 412 in the opening groove 411, the shifting block 503 on the large gear drives the fixed plate 1403 in the inclined tongue assembly 14 for clockwise rotation of the upper inclined tongue plate 10 through tooth cooperation, and the inclined tongue 1404 retracts into the lock shell against the action of the spring 1401, so as to complete unlocking.

The shifting block 503 on the large gear 5 can also be directly shifted to the upper shifting tongue plate 10 without teeth, such as a columnar shifting block 503 shown in fig. 14.

2. Motor lock

Referring to fig. 13, after the motor assembly 6 receives the locking signal of the control circuit a, the driving gear 602 rotates anticlockwise, the driving gear 602 drives the large gear 5 to rotate clockwise, the small gear 504 on the large gear 5 is meshed with the rack 413 on the elastic toothed plate 403, and is transited to be meshed with the main toothed bar 407 on the main tongue assembly 4, so that the main tongue assembly 4 is driven to move forward, the lock plunger 401 extends out of the lock shell, meanwhile, the limiting block 505 on the large gear 5 rotates along with the large gear 5 in the opening groove 411 from the unlocking gear 409 to the locking gear 408 when unlocking, the main tongue assembly 4 is limited, the shifting block 503 on the large gear 5 is separated from contact with the upper shifting inclined tongue plate 10, the inclined tongue assembly 14 extends out of the lock shell in a returning mode under the action of the spring 1401, and the upper shifting inclined tongue plate 10 is also returned along with the inclined tongue assembly 14, so that locking is completed.

3. Lock with emergency lock core

Referring to fig. 2, 11, 12 and 13, when the motor assembly 6 fails and cannot work, an emergency key is used to insert the lock cylinder 704 on the emergency lock cylinder assembly 7, the lock cylinder 704 is connected with the lock cylinder gear 701 through a clutch component (not shown in the drawings), and then the lock cylinder 704 is rotated to drive the lock cylinder gear 701 to rotate, and the large gear 5 is driven to rotate through the lock cylinder gear 701, so that unlocking and locking which are the same as those of the motor assembly 6 are realized.

4. Handle unlocking

Referring to fig. 2, 7, 8, and 15, the motor assembly 6 and the emergency plug assembly 7 are not operated, and the handle is used for unlocking. The handle 17 is pressed down, the handle thumb wheel 12 is rotated clockwise through the square rod 16, the upper lug 1202 on the handle thumb wheel 12 dials the middle dialing main tongue plate 11, the big gear 5 is driven to rotate through the cooperation of the middle dialing main tongue plate 11 and the small gear 504 on the big gear 5, so that the lock plunger 401 retracts the lock shell, meanwhile, the lower lug 1203 on the handle thumb wheel 12 dials the lower dialing inclined tongue plate 13, the lower dialing inclined tongue plate 13 acts on the fixed plate 1403 in the inclined tongue assembly 14, and the inclined tongue 1404 retracts the lock shell against the action of the spring 1401 to finish unlocking. Because the limit grooves 1103 and 1302 with arc lengths larger than the upper and lower protruding blocks 1202 and 1203 are respectively arranged on the middle shifting main tongue plate 11 and the lower shifting inclined tongue plate 13, the handle 17 is elastically reset at the moment, and the inclined tongue assembly 14 is also reset to extend out of the lock case under the action of the spring 404.

5. The handle is locked and the handle is not locked,

Referring to fig. 15, the handle 17 is lifted, the handle thumb wheel 12 is rotated anticlockwise by the square bar 16, the upper lug 1202 of the handle thumb wheel 12 acts on the main dialing tongue plate 11, the main dialing tongue plate 11 acts on the small gear 504 on the large gear 5, so that the lock plunger 401 extends out of the lock shell to complete locking, and the inclined tongue assembly 14 is automatically locked when the door is closed.

The invention is characterized in that:

1. The large gear 5 is adopted to be simultaneously linked with the main tongue component 4, the handle component, the inclined tongue component 14, the emergency lock core component 7 and the motor component 6, the structure is very simple, and the reliability and the service life of the lock body can be improved.

2. By adopting the integrated main tongue component 4, the main tongue connecting plate 402 is simultaneously provided with a main rack 407 meshed with a pinion 504 on the large gear 5, two overlapped elastic toothed plates 403 and 405 and an open groove 411 matched with a limiting block 505 on the large gear 5, and the upper parts of the open groove 411, which are positioned at the locking gear 408 and the unlocking gear 409, are provided with a yielding space 412 for accommodating the limiting block 505 of the large gear 5 to rotate for a certain angle. The locking gear 408 and the unlocking gear 409 on the front side and the rear side of the opening groove 411 are matched with the limiting block 505 on the large gear 5, so that the position of the main tongue assembly 4 can be reliably locked, and when the main tongue assembly 4 is subjected to external force, the main rack 407 cannot be deformed, and the main rack 407 is protected. The setting of the relief space 412 can enable the large gear 5 to continue rotating while the main tongue component 4 fully retracts the lock shell to be limited by the limiting block 505 of the large gear 5 during unlocking, and drive the inclined tongue component 14 to retract the lock shell to complete unlocking through the engagement of the shifting block 505 on the main tongue component and the upper inclined tongue plate 10, while allowing the large gear 5 to continue rotating under the action of inertia while the main tongue component 4 fully extends out of the lock shell to be limited by the limiting block 505 of the large gear 5 during locking. The relief space 412 of the opening groove 411 can enable the limiting block 505 on the large gear 5 to rotate to the relief space 412 when the large gear 5 is rotated by the key and the lock cylinder 704 under the condition that the motor assembly 6 is out of order in the locking state, so as to prevent the main tongue assembly 4 from being blocked. In addition, since the main tongue component 4 is provided with the neutral area and the elastic toothed plates 403 and 405, the large gear 5 drives the main tongue component 4 to continue to rotate no matter after unlocking or locking is completed, and at this time, the small gear 504 on the main tongue component enters the neutral area and is disengaged from the main toothed bar 407 to continue to be engaged with the rack of the elastic toothed plate, especially when the large gear 5 continues to rotate under the action of inertia after locking, the elastic toothed plate can play a role of buffering and protecting the large gear 5, and further play a role of protecting the motor component 6. When the main tongue assembly 4 is driven to complete the next locking and unlocking actions by the reverse rotation of the large gear 5, the small gear 504 on the large gear 5 can be in transition from being meshed with the rack on the elastic toothed plate to being meshed with the main toothed bar 407 on the main tongue assembly 4 in a neutral zone, so that the main tongue assembly 4 is driven to move.

3. According to the invention, the main bolt component 4, the inclined bolt component 14, the emergency lock cylinder component 7, the motor component 6, the handle component and the large gear 5 are arranged in the lock shell by adopting the base 8 and the pressing plate 17 to form a module, so that the matching precision of all the components can be ensured, the firmness of the lock body is improved, and the installation, the replacement and the maintenance are convenient.
