The drive shaft of the connecting gear 26 is formed with a lever 28 for moving the lock mechanism 30 interlocked with each other back and forth. Therefore, the door is locked and released by the rotation of the connection gear 26.

Then, the opening and closing detection sensor 40 installed on the upper part of the lock mechanism part 30 sends an electrical signal to the circuit board 50 from the opening and closing detection sensor 40, which detects this when the door is closed, and receives the signal from the circuit board 50. In this case, the motor 20 may be driven to open and close the door.

However, in the conventional door lock device, the number of components for transmitting power from the motor 20 to the lock mechanism part 30 is large and complicated, causing frequent failures in use, and increasing the cost of the product. In addition, the opening and closing detection sensor 40 for detecting the opening and closing state of the door has a problem that the protruding portion is damaged by direct contact with the door frame.

The present invention is to solve the conventional problems as described above, reducing the number of parts driven by the motor, by attaching a magnetic sensor on the door side of the door in the state of eliminating the mechanical operation of the risk of failure and wear It is an object of the present invention to provide a door lock having an automatic locking function for detecting opening and closing and an intrusion detection alarm function.

In order to achieve the above object, the present invention is provided with a door and an outer operation unit provided on the outer side of the door and having a key input unit, and a circuit board installed on the inner side of the door and controlling the electrical signal of the key input unit. A door locking device having an inner operating unit and a latch assembly including a disengagement driving unit installed between the outer operating unit and the inner operating unit and moving back and forth by the rotation of the rotating body. A motor provided in the inner operation part and driven by a control signal of the circuit board, a power transmission device connected to a drive shaft of the motor to open and close, a power transmission device connected to the power transmission device, and one end of the inner operation part A unlocking drive unit having a manual lever protruding to an outer surface thereof and having a lever connected to the pivoting body of the latch assembly at the other end thereof; It provides a door locking device having an automatic locking function and an intrusion detection alarm function, characterized in that formed.
