SMART DOOR LOCK AND COMPOSITE MECHANISM FOR LOCKING AND UNLOCKING
Document Type and Number:
WIPO Patent Application WO/2019/149188
Kind Code:
A1
Abstract:
A composite mechanism for locking and unlocking comprises a driving mechanism, a transmission mechanism, a planetary transmission mechanism, a manual gear (7), a manual knob (8), a main shaft (9), a panel (11), and a base plate (12). The driving mechanism engages with a master planetary gear (5) of the planetary transmission mechanism via the transmission mechanism. The manual knob (8) engages with a slave planetary gear (6) of the planetary transmission mechanism via the manual gear (7). A first end of the main shaft (9) is rotatably mounted on the panel (11). A second end of the main shaft (9) is rotatably mounted on the base plate (12), and engages with a lock cylinder (14) to ensure synchronized rotation. A middle portion of the main shaft (9) engages with a center hole of a planetary carrier (4) of the planetary transmission mechanism to ensure synchronized rotation. The invention further relates to a smart door lock employing the composite mechanism.
