The first clutch gear 92 or the third clutch gear 94 meshes with the secondary gear 95, and the secondary gear 95 meshes with the transmission gear disk 8, thereby driving the transmission gear disk 8 to rotate. The meshing of the first clutch gear 92, the third clutch gear 94 and the secondary gear 95 is based on the forward and reverse rotation of the motor 7, so that the first clutch gear 92 or the third clutch gear 94 meshes with the secondary gear 95.

[0048] like Figure 10As shown, the clutch gear set 15 is in a disengaged state, one end of the clutch lever 102 drives the clutch lever 96 to swing, and the clutch swing plate 91 swings around the second clutch gear 93 as the axis, and the first clutch gear 92 and the third clutch gear 94 are disengaged from the secondary gear 95, so that the transmission gear plate 8 and the secondary gear 95 are not controlled by the motor 7.

[0049] The full-automatic intelligent lock opens the lock by an electric mode, and the process is as follows: Figure 3 As shown, the main tongue assembly 4 and the turnover tongue assembly 5 are in a closed state, the motor 7 works, drives the transmission gear plate 8 to rotate through the transmission gear set 14 and the clutch gear set 15, and when the driving column 10 on the transmission gear plate 8 rotates, the driving column 10 drives the rotating disc 9 to rotate, at the same time, the driving column 10 drives the turnover tongue limiting plate 43 to rotate, the turnover tongue limiting plate 43 drives the moving plate 41 to move, and the moving plate 41 drives the turnover tongue limiting plate 42 to move, so that the turnover tongue limiting plate 42 is in an un-limited state, and the turnover tongue assembly 5 can be turned over to open the lock, at the same time, the driving block 13 on the rotating disc 9 moves in the driving gap 63 on the driving plate 62, so that the driving plate 62 drives the main tongue 61 to move inward, at the same time, the movement of the driving plate 62 drives the second fan-shaped tooth 75 to swing, the second fan-shaped tooth 75 is engaged with the second rack 77 of the sliding part 73, so as to drive the sliding part 73 to slide, the first rack 76 of the sliding part 73 is engaged with the first fan-shaped tooth 74, so as to drive the first fan-shaped tooth 74 to rotate, the first fan-shaped tooth 74 is hingedly connected with the upper auxiliary tongue assembly 31, so as to drive the upper auxiliary tongue assembly 31 to move inward, the working principle of the lower auxiliary tongue assembly 32 is the same as that of the upper auxiliary tongue assembly 31, and the lock is opened.

[0050] The difference between the manual opening mode and the electric opening mode is that the electric opening mode drives the transmission gear plate 8 to rotate through the transmission gear set 14 and the clutch gear set 15, and the specific process of the manual opening mode is as follows: the key drives the lock core 18 to rotate, drives the lock core 18 to drive the lock core lever 19 to rotate and swing, the rotation and swing of the lock core lever 19 can drive the clutch lever 102 to swing, one end of the clutch lever 102 drives the clutch lever 96 to swing, so that the clutch swing plate 91 swings around the second clutch gear 93 as the axis, and the first clutch gear 92 and the third clutch gear 94 are disengaged from the secondary gear 95, so that the transmission gear plate 8 and the secondary gear 95 are disengaged from the transmission gear set 14 and can rotate freely, at the same time, the rotation and swing of the lock core lever 19 drives the moving plate 41 through the transmission lever 20, the moving plate 41 drives the turnover tongue limiting plate 42 to move, so that the turnover tongue limiting plate 42 is in an un-limited state, and the turnover tongue assembly 5 can be turned over to open the lock, finally, the driving block 13 on the rotating disc 9 drives the driving plate 62 and the main tongue 61 to move inward, and the lock is opened manually.
