Title:
ELECTRIC LOCK BODY
Document Type and Number:
WIPO Patent Application WO/2022/127179
Kind Code:
A1
Abstract:
The present application provides an electric lock body. The electric lock body comprises a housing; a driving mechanism comprising a motor, a planetary gear assembly and a holder, the planetary gear assembly comprising ring gears, planetary gears and sun gears, the motor being rotatably connected to the sun gears, the planetary gears being rotatably connected between the sun gears and the ring gears, the holder being provided on one side of the planetary gear assembly, both the ring gears and the sun gears abutting against the holder, and the planetary gears being connected to the holder; and lock bolts connected to the holder, when the holder rotates, the holder being able to drive the lock bolts to move, so that the lock bolts are switched between an unlocking state in which the lock bolts are accommodated in the housing and a locking state in which the lock bolts protrude from the housing. The driving mechanism provided in the present application achieves unlocking and locking of a door by using the motor to control the rotation of the sun gears, or by means of controlling the ring gears to rotate, thereby increasing the method for controlling a door lock, avoiding the problem that the door cannot be unlocked or locked due to a damage occurring to a motor in a single motor lock, and reducing the difficulty and risk of unlocking the door.
