Digital door lock device

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.

Description

technical field [0001] The present invention relates to a digital door lock device, specifically, it can be easily installed on all doors with handrails such as outdoor and indoor doors, sliding doors, etc. Working digital door lock device. Background technique [0002] Generally speaking, in order to prevent and protect security, door locks are provided at the entrances and exits of families or companies and stores. In recent years, digital door locks have gradually replaced mechanical door locks. [0003] In order to activate these digital door locks, a method of touching an electronic key to a contact part of the electronic key, a method of pressing a keyboard using a mechanical switch such as a tact switch or a membrane switch to input a password, and a method of using a fingerprint are currently used. [0004] Existing digital door locks generally include: an outdoor unit installed on the outside of the door and having an outdoor handle; an indoor unit installed on the...

AI Technical Summary

Problems solved by technology

[0010] In addition, most of the existing digital door lock devices set the position of the handle on the left or right side of the door so that the handle can be easily rotated in the direction of opening the door

[0011] At this time, if there is a left-hand handle that rotates clockwise and a right-hand handle that rotates counterclockwise, when installing according to the rotation direction of the handle, there is a problem that the left-hand / right-hand handle cannot be flexibly selected according to the direction of opening the door

[0012] In addition, in the existing digital door lock device, the rotational force of the handle or handle is transmitted to the locking device provided inside, so that the constituent parts constituting the locking device are damaged due to mechanical wear or impact, etc., and due to accumulated fatigue etc., reducing its durability

[0013] In addition, in the existing digital door lock device, the main body of the door lock has a circuit part and an authentication part, so there is a problem that the volume of the main body is relatively large.
