DRIVING MECHANISM FOR DOOR LOCK, AND DOOR LOCK
Document Type and Number:
WIPO Patent Application WO/2022/068480
Kind Code:
A1
Abstract:
Provided in the present application are a driving mechanism for a door lock, and a door lock. The driving mechanism comprises an electric motor; a planet gear assembly, which comprises a gear ring, a planet gear and a sun gear, the electric motor being rotatably connected to the sun gear, the gear ring being provided with an accommodating space, the planet gear and part of the sun gear being arranged in the accommodating space, and the planet gear being rotatably connected between the sun gear and the gear ring; and a retainer, which is arranged on one side of the planet gear assembly, the gear ring and the sun gear abutting against the retainer, and the planet gear being connected to the retainer. The sun gear rotates under the drive of the electric motor when the gear ring is in a fixed state. The gear ring can be controlled to rotate when the sun gear is in a fixed state. A door is opened and closed by means of two manners of using the electric motor to control the sun gear to rotate or directly controlling the gear ring to rotate, thereby adding a method for controlling the door lock, solving the problem that a door cannot be opened and closed because an electric motor is damaged in a single motor lock, and reducing the difficulty and risk associated with opening the door.
