Problems solved by technology

However, it often happens when the rotating shaft has not been rotated to the right position. Due to the internal jamming of the gear set, the current will also rise, resulting in false locking. Locked, but the user thinks it is locked, so there is a hidden danger to the safety of the property in the house

Abstract

The invention relates to the field of locks, and discloses a lock and a speed reducer thereof. The speed reducer comprises a shell (4), a motor (1) and a bevel gear (2), wherein the shell (4) is connected with the motor (1), the shell (4) is provided with a lug (41), the lug (41) is provided with a screw hole (42), and the motor (1) is provided with the bevel gear (2); and the speed reducer further comprises a first gear component (3), a gear set, a driving gear (5) and a rotating shaft (8), wherein the bevel gear (2) is meshed with the first gear component (3), the first gear component (3) ismeshed with the gear set, the gear set is meshed with the driving gear (5), the rotating shaft (8) is arranged on the driving gear (5), and at least one first magnetic part (33) is arranged on the first gear component (3). The lock has the advantages that unlocking and locking of the intelligent lock are controlled through electric pulse detection, and false locking is prevented.

Description

technical field [0001] The invention relates to the field of locks, in particular to a lock and a speed reduction device thereof. Background technique [0002] Existing ordinary mechanical locks use ordinary mechanical unlocking devices to open and close, which is poor in anti-replication and inconvenient to use. Therefore, smart locks are more and more convenient to use in people's lives. Application number: The invention patent of CN201821436638.X discloses the smart lock structure, which is described as follows; it has a motor, a shaft connected to the handle, and a housing. The shaft is assembled on the housing, and the clutch gear is assembled on the shaft. Under normal conditions, the clutch gear By disconnecting the clutch mechanism from the drive system of the motor, the rotation of the rotating shaft can be manually driven. The above solution is further as follows: the clutch mechanism is a compression spring, the compression spring is sleeved on the rotating shaft...
