Figure 3 is a side view showing a coupling structure of the driven gear and the rotating gear coupled to the shaft member according to the present invention, Figure 4 is a schematic view showing a locked state of the door lock device according to the present invention.

First, when a user inputs a password, power is applied to the driving motor 211 by an input signal, and rotation is controlled.

The motor 211 transmits power to the reduction unit 220 by rotating the worm gear 215. The output is increased through the reduction unit 220 is output to the outside through the driven gear 230.

At this time, the driven gear 230 is composed of a combination of the lower gear 231 and the upper gear 233, the upper gear 233 is formed a section tooth portion 233a to form a gear value only in the 90 ° section and In addition, the interval value portion 233a maintains a standby state separated from the interval value portion 253 of the rotation gear 250 in a state where power is not applied (that is, the dead bolt is locked).

When the key or summton (a kind of locking lever installed in the door) interlocked with the through hole 245 of the shaft member 240 is operated in the standby state as described above, the dead bolt does not interfere with the driven gear 230. By rotating the interlocking arm 270, the dead bolt 280 can be manually controlled in a locked and released state.

As a result, the driving of the motor 211 can be controlled.

At this time, the dead bolt 280 can be locked by rotating the dead bolt interlocking arm 270 using the summton inside the door, even if the rotating gear 250 is reversely rotated together with the dead bolt interlocking arm 270. The present invention prevents the problem that the reverse power is applied to the motor 211 or the worm gear 215 by maintaining the disconnected state of the rotary gear 250 and the driven gear 230 in the state that the power is not applied. You can do it.
