To activate the locking and releasing device.

At this time, the operation method of releasing the locking and releasing device 100 is made as shown in Figs. 3a, b and c.

First, when a signal is determined that the authentication means is legitimate, the rotary member 122 eccentrically coupled to the rotating shaft of the motor 121 by generating a driving force to the motor 121 rotates the driving pin 122s at a predetermined angle By moving the engaging groove (122b) accommodating the drive pin (122a) by moving the movement member 131 a certain section in the horizontal direction.

As described above, the follower member 132 continuously receiving the cam pin 133 by the mover member 131 moved in the horizontal direction is converted in the vertical direction of the inclined moving hole 132a.

Thereafter, the pressing piece 132c of the driven joint member 132 presses the switch piece 141 accommodated in the guide space jaw 112 and passes through the guide hole 142a of the interlocking plate member 142 to connect the connecting member 143. The end of the switch piece 141 is moved to the engaging groove (143b) side of the).

Here, the switch piece 141 moved by the follower member 132 is the pressure of the switch piece 141 while pressing the spring 142 between the reference pin 143 and the end of the mounting space 141a located therein. The end is inserted into the locking groove 143b of the connecting member 143. (See FIG. 3B).

When the switch piece 141 is moved in an internal state in the locking groove 143b of the connecting member 143, the connecting member 143 for releasing the interlocking plate member 142 and the clamp 11 to interlock with the handle 12. Is set in such a state that it can be integrally interlocked by the switch piece 141, the rotational force of the handle 12 is transmitted to the connection member 143, and the electric shaft coupled to the connection member 143 transmits the rotational force to the electric joint. To release the lock 11 (see FIG. 3C).

As such, after the locked state is released, the handle 12 is rotated and restored to its original state so that the switch piece 141 is positioned at the position of the inlet end 112b of the guide space jaw 112, and then the spring 141b. The end of the switch piece 141 is separated from the locking groove 143b of the connecting member 143 by releasing the interlocking property of the interlocking plate 142 and the connecting member 143 and then the verification step of the authentication means. Prepare for the release step (see Figure 3a).

In addition, the locking member coupled to the key bundle 160 when the key is inserted into the key groove 162 and then rotated forward or reverse to manually release the clamp 11 through the user's key without verification of the authentication means. As the 161 rotates integrally, the locking jaw 122b of the driven member 132 is moved in the horizontal direction to allow the movable member 131 to be moved in the vertical direction, thereby locking and releasing the device through the key. It may be manually operable (see FIGS. 4A and 4B).

On the contrary, when the verification step of the authentication means generates an error signal or rotates the handle 12 without the verification step of the authentication means, the driving force of the driving unit is not generated, so that the switch piece guide hole 142a of the interlocking plate material 142. Only the interlocking plate 142 is idling in a state where it is mounted in such a way as to prevent the release state of the clamp (see FIG. 2).

The digital door lock locking and releasing device of the present invention converts the rotational motion of the motor into horizontal and vertical linear motion to enable the unlocking and locking of the digital door lock, thereby simplifying the mechanical coupling structure to enable a reliable release and locking operation state. It is effective.

In addition, the digital door lock locking and unlocking device of the present invention simplifies the transmission process of the power transmitted from the motor, thereby minimizing electric consumption, thereby enabling long-term use of the digital door lock and reducing overall maintenance costs. .

In addition, the digital door lock locking and releasing device of the present invention can be manufactured by the thickness of the digital door lock can be made thinner by minimizing the volume of the digital door lock according to the electric joint through the thin-dong copper member and driven member in the form of a plate. It is effective.
