Title:
DIGITAL DOOR LOCK DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/021672
Kind Code:
A1
Abstract:
The present invention relates to a digital door lock device. According to one aspect of the present invention, a left-handed setting section and a right-handed setting section are arranged on a rotational housing which is provided on a door lock body and is coupled to a lever, and a setting section moving part is moved to the left-handed setting section and the right-handed setting section during assembly such that left-handed/right-handed levers can be selected relative to an opening direction of a door, thereby providing flexibility of installation. Furthermore, according to another aspect of the present invention, a locking and unlocking module is provided with a slip gear unit which is driven in a normal engagement state when torque does not exceed a certain value, and which causes transmission torque to idle by the slipping of the gear unit when the torque has the certain value or more, thereby reducing damage to components that constitute a lock device due to mechanical abrasion or impact or the like and the accumulated fatigue when rotatory power caused by a handle or a lever is transferred to the lock device that is installed inside, and reducing power consumption by preventing an overload of a motor, and further, rotatory power is transferred from a clutch unit to a gear unit of the motor even when coupled to a mechanical lock, thereby preventing a gear unit of a reducer from being worn out.
