The present invention relates to a digital door lock having a panic release detection function. More specifically, when the user unlocks the panic release knob while the mortise of the door lock is locked, the panic release knob detects the movement of the panic release knob and stops the driving of the motor in the locking direction, and the lever drive gear is turned on. A digital door lock with panic release detection to protect the gears in the motor and mortis by moving to a neutral position.

Currently, many homes and offices are using digital door locks that electronically control the overall locking and unlocking operation of the door lock by using an electronic key (Key) as a door opening and closing device and a microprocessor unit (MPU).

In general, when a user uses a digital door lock, if a user inputs a predetermined authentication means into the digital door lock, the digital door lock performs authentication to determine whether the authentication means is legitimate. It works to release Mortis.

After that, when the user opens the door using the external handle and enters the room and closes the door, the digital door lock detects that the door is closed through the sensor and operates the dead bolt drive to automatically return the mortis to the locked state. Either enable or manually activate Mortis by pressing a button.

When the mortis is operated in the locked state, the motor in the mortis rotates the motor shaft gear in the locking direction, and the lever driving gear engaged with the rotating motor shaft gear rotates to move the dead bolt operating lever to move the dead bolt to the locked position. do.

1 is a view showing in detail the dead bolt operating lever and the bevel gear. The lever driving gear described above means the bevel gear 120 in FIG. 1.

2 to 5 are views showing the position change of the dead bolt operating lever 110 and the locking groove 128 when the dead bolt is locked and unlocked.

The rotating shaft 112 of the dead bolt operating lever 110 shown in Figure 1 is fitted to the bevel gear 120 is connected to the dead bolt.

2 is a view showing that the dead bolt is locked and the bevel gear is in a neutral position. When the mortise release operation by the drive motor starts when the dead bolt is locked, the bevel gear 120 engaged with the motor shaft gear (not shown) while the motor rotates is rotated clockwise about the gear rotation shaft shown in FIG. Rotated. At this time, the first pressing portion 122 of the bevel gear 120 rotates the lever portion 114 in the release direction while applying a force to the lever portion 114.

Referring to FIG. 3, which shows a state immediately after the first pressing part 122 applies the force to the lever part 114 to the dead bolt, the operating lever 110 is in the unlocked position and the bevel gear 120 is shown. The locking groove 128 is placed in a non-neutral position. Therefore, when the mortise lock operation is started by the drive motor afterwards, the locking groove 128 should move to the neutral position in order to perform the dead bolt lock operation without being spaced apart. To this end, the bevel gear 120 is rotated counterclockwise so that the motor rotates to move the locking groove 128 to the neutral position. Therefore, when the mortis unlocking operation is completed, the state of FIG. 4 is obtained.

When the bevel gear 120 and the operating lever 110 are in the state as shown in FIG. 4, when the Mortis locking operation is started by the driving motor, the motor rotates so that the bevel gear 120 is rotated counterclockwise. 124 moves the dead bolt in the locking direction while applying the force to the lever 114 in the counterclockwise direction.

Referring to FIG. 5, which illustrates a state immediately after the second pressing part 124 moves the dead bolt in the locking direction while applying the force to the lever part counterclockwise, the locking groove 128 is not neutral. Will be placed in. Therefore, when the mortise unlocking operation is started by the drive motor afterwards, the locking groove 128 must be moved to the neutral position in order to perform the dead bolt unlocking operation without being spaced apart.

To this end, the bevel gear 120 is rotated clockwise so that the motor rotates to move the locking groove 128 to the neutral position. Therefore, when the Mortis lock operation is completed, the state of FIG. 2 is obtained.

In this normal unlocking and locking operation, no abnormal physical shock is applied to the gears in the motor and the mortis.

However, a problem occurs when the user tries to unlock the door lock by moving the panic release knob while the dead bolt of Mortis moves to the locked position after the user enters the room.

If the motor is driven and the bevel gear rotates counterclockwise, and the user pushes the panic release knob to reopen the door lock during the locking operation, the force is transmitted in the opposite direction to the dead bolt moving in the locking direction. .

The force applied to the dead bolt is transmitted to the bevel gear and the motor shaft gear meshed with the bevel gear through the actuating lever connected to the dead bolt, and the motor is overloaded as the load in the direction opposite to the direction in which the motor is intended to rotate. Occurs. As the user repeatedly rotates the panic release knob in the opposite direction to the unlocking direction, such a shock accumulates on the gears in the motor and the mortise, causing a problem in the gears and the motor in the mortise and shortening the lifespan.

In addition, when the user turns the panic release knob is not stronger than the motor driving the dead bolt to rotate the gear, the door does not open quickly.

In order to solve the above problems, the present invention detects the movement of the panic release knob when the user rotates the panic release knob while the mortis of the door lock is locked to drive the motor in the locking direction. Its main purpose is to protect the gears in the motor and mortis by stopping and moving the lever drive gear to the neutral position.
