[0034] The specific solutions and embodiments of this utility model will be further described with reference to the accompanying drawings.

[0035] As shown in the figure, a self-springing motor lock body includes a guide plate 1 and a lock box assembly 2 connected to the guide plate 1. The latch of the latch assembly 3 and the latch of the latch assembly 5 enter and exit the lock box assembly 2 through the guide plate 1. The lock box assembly 2 is also provided with a latch fork assembly 4, a latch trigger hook assembly 6, and a latch actuating plate assembly 9. The latch actuating plate assembly 9 is slidably and rotatably disposed at the rear of the latch assembly 3 and connected to the lock box assembly 2. A latch actuating plate torsion spring 10 is disposed at the pivot of the latch actuating plate assembly 9 and is used to push the latch actuating plate assembly 9 to rotate, so that the latch assembly 3 pops out. The latch fork assembly 4 is detachably abutted against the rear end of the latch assembly 5. The latch fork assembly 4 is disposed in the middle of the lock box assembly 2. The latch trigger hook assembly 6 is provided on the inner side of the lock box assembly 2. The latch trigger hook assembly 6 is detachably hook-connected to the latch fork assembly.

[0036] The lock box assembly 2 also includes a motor reduction gearbox 24 and a transmission gear 23. The slanted tongue fork assembly includes a slanted tongue push rod 19 and a slanted tongue fork 20. One end of the slanted tongue fork 20 is connected to one end of the slanted tongue push rod 19 through a slanted tongue fork connecting rivet 21, and the other end of the slanted tongue push rod 19 abuts against the transmission rivet 22 on the transmission gear 23.

[0037] The motor unlocking principle is as follows:

[0038] When the motor is turned on, the output gear 25 of the motor reducer drives the transmission gear 23 to rotate. At the same time, the transmission rivet 22 on the transmission gear 23 pushes the tongue shift fork assembly, which in turn pushes the lock tongue shift plate assembly and the tongue shift fork to retract the lock tongue assembly 3 and the tongue assembly to complete the unlocking. Meanwhile, the tongue shift fork 20 pushes open the starting hook 17 and hook-shaped connection with the tongue assembly. Therefore, the extension of the tongue assembly when the motor rotates will not trigger the lock tongue assembly 3 to pop out.

[0039] The end of the oblique tongue push rod 19 is provided with a motor transmission surface 1010, which abuts against the transmission rivet 22. The middle part of the oblique tongue push rod 19 is provided with a transmission point 1008 and a lock cylinder rotation angle 1009.

[0040] The other end of the oblique tongue fork 20 abuts against the lower part of the oblique tongue assembly 5. The oblique tongue fork 20 is provided with a rotating block hole and a clutch protrusion 1007 at its outer end.

[0041] The rear of the latch assembly 3 is provided with a transmission locking hole 1001 and a guide groove 1002. The latch assembly 3 slides relative to the latch actuating plate assembly 9 through the guide groove 1002. One side of the latch actuating plate assembly 9 is rotatably connected to the transmission locking hole 1001 through the first latch actuating plate rivet 12. The latch actuating plate assembly 9 drives the latch assembly 3 to move back and forth.

[0042] The latch actuating plate assembly includes a latch actuating plate 11 and a second latch actuating plate rivet 13. The latch actuating plate 11 has a limiting angle 1003 on its outer side. The limiting angle 1003 abuts or separates from one end of the latch triggering hook assembly 6. The second latch actuating plate rivet 13 abuts or separates from the latch actuating plate torsion spring 10.

[0043] The latch trigger hook assembly 6 includes a latch limiting plate 14, a trigger hook spring 7, and a trigger hook 17. One end of the latch limiting plate 14 is connected to the trigger hook 17 via a trigger hook connecting rivet 16. The end of the trigger hook 17 is provided with multiple sawtooth-shaped steps. The trigger hook 17 is connected to the lock box plate assembly 2 via a trigger hook clutch rivet 15. The upper trigger hook 17 is also provided with a trigger hook spring rivet 18. One end of the trigger hook spring 7 is fixed to the lock box plate assembly 2, and the other end is connected to the trigger hook spring 7 rivet.

[0044] The other end of the latch limiting plate 14 is provided with a locking plate slot 1004, which can be detachably abutted against the limiting angle 1003 of the latch toggle plate assembly 9.

[0045] The start hook 17 has a start hook notch 1005 at its end, and the start hook notch 1005 is detachably hooked to the bottom end of the oblique tongue assembly 5.

[0046] The rear end of the tongue assembly 5 is provided with a locking tongue baffle 1006, which is detachably abutted against the tongue shift fork assembly 4.

[0047] One end of the lock tongue actuating plate torsion spring 10 extends into the screw limiter inside the lock box plate assembly 2.

[0048] The passively triggered latch automatically pops out to complete the locking, effectively avoiding friction and collision between the bolt assembly and the door frame, and eliminating the hassle of locking with a key or other manual methods; the unique transmission opening clutch structure is simple, stable and reliable, and the inner handle allows for quick opening.

[0049] The locking process of the automatic mechanical lock is as follows:

[0050] After the latch assembly 5 retracts, the latch triggers the start hook assembly 6, the latch fork assembly 4 separates, and after locking, the latch actuating plate torsion spring 10 pushes the latch actuating plate assembly 9 to rotate, pushing the main latch assembly 3 to pop out and complete the locking.

[0051] The mechanical automatic lock opening process is as follows:

[0052] Unlocking with the key and handle involves rotating the rotating block 8, which pushes the latch fork assembly 4, which in turn pushes the latch actuating plate assembly 9 and the latch fork 20. At the same time, the main latch assembly 3 and the latch assembly 5 are retracted to complete the unlocking. Simultaneously, the latch fork 20 pushes open the starting hook 17 and hooks with the latch assembly 5, so the latch will not be triggered to pop out when the handle and key open the latch assembly 3 and the latch assembly 5.
