[0031] The above-mentioned latch bolt assembly 14, emergency lock core assembly 7, motor assembly 6, handle assembly, and the matching structure between the handle assembly and the latch bolt assembly 14 are all prior art.

[0032] Here’s how it works:

[0033] 1. Motor unlocking

[0034] See Figure 2 , Fig.11 , Fig.12The motor assembly 6 drives the active gear 602 to rotate clockwise according to the unlocking signal such as the read fingerprint and password, and drives the large gear 5 to rotate counterclockwise. The small gear 504 on the large gear 5 drives the main tongue assembly 4 to move backward by meshing with the main rack 407 on the main tongue assembly 4, so that the lock bolt 401 is retracted into the lock shell. At the same time, the limit block 505 on the large gear 5 rotates with the large gear 5 in the opening groove 411 from the locking gear position 408 when locked to the unlocking gear position 409, limiting the main tongue assembly 4, and then the large gear 5 continues to rotate in the clearance space 412 in the opening groove 411, and the shifting block 503 thereon drives the upper shifting oblique tongue plate 10 to rotate clockwise through the tooth cooperation to act on the fixed plate 1403 in the oblique tongue assembly 14, overcome the action of the spring 1401 to retract the oblique tongue 1404 into the lock shell, and complete the unlocking.

[0035] The shifting block 503 on the large gear 5 may also be provided with no teeth, and the upper shifting oblique tongue plate 10 may be shifted directly, such as Fig.14 The cylindrical shift block 503 is shown.

[0036] 2. Motor lock

[0037] See Fig.13 After the motor assembly 6 receives the locking signal from the control circuit A, the active gear 602 rotates counterclockwise, and the driving gear 602 drives the large gear 5 to rotate clockwise. The small gear 504 on the large gear 5 first meshes with the rack 413 on the elastic toothed plate 403 and then meshes with the main rack 407 on the main tongue assembly 4, driving the main tongue assembly 4 to move forward, so that the lock bolt 401 extends out of the lock housing. At the same time, the limiting block 505 on the large gear 5 rotates with the large gear 5 in the opening groove 411 from the unlocking gear position 409 to the locking gear position 408 when unlocking, limiting the main tongue assembly 4, and the shifting block 503 on the large gear 5 is disengaged from the contact with the upper shifting oblique tongue plate 10. The oblique tongue assembly 14 returns to its position and extends out of the lock housing under the action of the spring 1401, and the upper shifting oblique tongue plate 10 also returns with the oblique tongue assembly 14 to complete the locking.

[0038] 3. Emergency lock cylinder unlocking and locking

[0039] See also Figure 2 , Fig.11 , Fig.12 , Fig.13 When the motor assembly 6 fails and cannot work, use the emergency key to insert the lock core 704 on the emergency lock core assembly 7, connect the lock core 704 with the lock core gear 701 through the clutch component (not shown in the figure), and then rotate the lock core 704 to drive the lock core gear 701 to rotate, and drive the large gear 5 to rotate through the lock core gear 701, so as to achieve the same unlocking and locking as the motor assembly 6.

[0040] 4. Unlock the handle

[0041] See Figure 2 , Figure 7 , Figure 8 , Fig.15 , when the motor assembly 6 and the emergency lock core assembly 7 are not working, the handle can be used to unlock. Press the handle 17 downward, rotate the handle dial 12 clockwise through the square rod 16, and the upper protrusion 1202 on the handle dial 12 dials the middle dial main tongue plate 11, and the middle dial main tongue plate 11 cooperates with the small gear 504 on the large gear 5 to drive the large gear 5 to rotate, so that the lock bolt 401 retracts into the lock shell, and at the same time, the lower protrusion 1203 on the handle dial 12 dials the lower dial oblique tongue plate 13, and the lower dial oblique tongue plate 13 acts on the fixed plate 1403 in the oblique tongue assembly 14, overcomes the action of the spring 1401, and retracts the oblique tongue 1404 into the lock shell, completing the unlocking. Since the middle dial main tongue plate 11 and the lower dial oblique tongue plate 13 are respectively provided with limiting grooves 1103 and 1302 with arc lengths greater than the upper and lower protrusions 1202 and 1203, the handle 17 is elastically reset at this time, and the oblique tongue assembly 14 also returns to the lock shell under the action of the spring 404.

[0042] 5. Lock the handle.

[0043] See Fig.15 , lift the handle 17, rotate the handle dial 12 counterclockwise through the square rod 16, the upper protrusion 1202 of the handle dial 12 acts on the middle main tongue plate 11, and the middle main tongue plate 11 acts on the small gear 504 on the large gear 5, so that the lock bolt 401 extends out of the lock shell, completing the locking, and the inclined tongue assembly 14 is automatically locked when the door is closed.

[0044] Features of the present invention:

[0045] 1. The large gear 5 is used as a component to simultaneously link with the main tongue assembly 4, the handle assembly and the oblique tongue assembly 14, the emergency lock core assembly 7, and the motor assembly 6. The structure is very simple and can improve the reliability and service life of the lock body.

[0046] 2. An integrated main tongue assembly 4 is adopted. The main tongue connecting plate 402 is provided with a main rack 407 meshing with the pinion 504 on the large gear 5, two overlapping elastic tooth plates 403 and 405, and an opening groove 411 cooperating with the stop block 505 on the large gear 5. The opening groove 411 is located at the upper part of the locking gear 408 and the unlocking gear 409 and is provided with a clearance space 412 for accommodating the stop block 505 of the large gear 5 to rotate a certain angle. The locking gear 408 and the unlocking gear 409 on the front and rear sides of the opening groove 411 cooperate with the stop block 505 on the large gear 5 to reliably lock the position of the main tongue assembly 4. When the main tongue assembly 4 is subjected to external force, the main rack 407 will not be deformed, thereby protecting the main rack 407. The setting of the clearance space 412 allows the large gear 5 to continue to rotate when the main tongue assembly 4 is fully retracted into the lock housing and limited by the limit block 505 of the large gear 5 during unlocking, and the shifting block 505 thereon engages with the upper shifting oblique tongue plate 10 to drive the oblique tongue assembly 14 to retract into the lock housing to complete unlocking; while when locking, the main tongue assembly 4 is fully extended out of the lock housing and limited by the limit block 505 of the large gear 5, and the large gear 5 is allowed to continue to rotate under the action of inertia. The clearance space 412 of the opening groove 411 allows the limit block 505 on the large gear 5 to rotate to the clearance space 412 when the large gear 5 is rotated by the key and the lock core 704 in the case of failure of the motor assembly 6 in the locked state, so as to prevent the main tongue assembly 4 from being stuck. In addition, since the main tongue assembly 4 is provided with a neutral area and elastic tooth plates 403 and 405, the large gear 5 drives the main tongue assembly 4 to continue to rotate no matter whether it is unlocked or locked. At this time, the small gear 504 on it enters the neutral area and disengages from the main rack 407, and continues to mesh with the rack of the elastic tooth plate. In particular, when the large gear 5 continues to rotate under the action of inertia after locking, the elastic tooth plate can play a buffering and protective role for the large gear 5, and then play a role in protecting the motor assembly 6. When the large gear 5 rotates in the opposite direction to drive the main tongue assembly 4 to complete the next locking and unlocking action, the small gear 504 on the large gear 5 can transition from meshing with the rack on the elastic tooth plate to meshing with the main rack 407 on the main tongue assembly 4 in the neutral area, driving the main tongue assembly 4 to move.

[0047] 3. The present invention adopts the base 8 and the pressure plate 17 to install the main tongue assembly 4, the oblique tongue assembly 14, the emergency lock core assembly 7, the motor assembly 6, the handle assembly and the large gear 5 in the lock housing to form a module, which can ensure the accuracy of the matching of each component, improve the firmness of the lock body, and facilitate installation, replacement and maintenance.
