Description

Technical Field

[0001] The utility model relates to the field of intelligent door locks, in particular to an intelligent door lock clutch motor. Background Art

[0002] Smart door locks have become an essential tool for modern smart communities. Every household is popularizing the use of smart door locks to improve the intelligence level of smart communities. Smart door locks usually use motors to drive the lock core through a gear set to open and close the door lock. When the smart door lock is out of power, it can only be unlocked by twisting the lock core with a key. Since the lock core is connected to the gear set and the motor drive, the user needs to twist the key hard to turn the lock core to unlock it. When the user twists the key to turn the lock core, the lock core drives the gear set and the motor to rotate to unlock it. This type of door lock structure makes it very difficult to unlock, which is inconvenient for the elderly and children to use, and the user experience is not good. Summary of the invention

The meshing transmission of the first drive gear 61 and the lock core gear 12 can prompt the plate frame 7 to continue to rotate clockwise around the second rotating shaft 81, so that the first drive gear 61 is completely combined with the lock core gear 12, and at the same time, the second drive gear 62 is completely separated from the lock core gear 12, so that the clockwise rotation of the first drive gear 61 can drive the lock core gear 12 to rotate counterclockwise to unlock or lock.

[0035] In another embodiment, the working principle of the smart door lock clutch motor is as follows: the servo motor 3 can drive the first double gear 5 to rotate clockwise or counterclockwise through the screw rod 4.

The overall structural design makes the smart lock have the advantages of high unlocking efficiency, high locking efficiency, time-saving unlocking or locking, labor-saving unlocking or locking, and good user experience when unlocking or locking when there is a power shortage. It effectively solves the problem that the smart door locks on the market currently have the structure that the lock cylinder is connected to the gear set and the motor drive, which causes the user to twist the key hard to turn the lock cylinder to unlock or lock when there is a power shortage, resulting in low manual unlocking or manual locking efficiency, time-consuming manual unlocking or manual locking, labor-intensive manual unlocking or manual locking, and poor user experience.
