Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The overall structure of a door lock motor with dead latch function according to the present invention is shown in Figs.

As can be seen from the above description, the door lock motor with the dead latch function according to the present invention is such that the dead bolt 100 and the latch bolt 200 are received and engaged with the groove of the striker in the normal locked state, The deadbolt key lever 102 and the deadbolt trolley 103 that rotate by the key cylinder 500 that rotates by the motor power cause the deadbolt 100 to slide in and out of the face plate while sliding.

In the present invention, the deadbolt panic lever 101 is connected to the recess of the deadbolt key lever 102 by a seal rod 108, and on the lower side of the deadbolt panic lever 101, The protrusions 403 formed on the rotor 402 closely contact the panic protrusions 105 and the stop jaw 107 of the lever cam and the stop jaws 106 of the latch stopper are formed on the other side downward.

When the dead bolt panic lever 101 is turned upward by the deadbolt key lever 102 to be rotated, the latch stopper stopper 106 of the dead bolt panic lever 101 and the stopper stopper 106 of the lever cam 101 The protrusion 404 of the lever cam and the protrusion 204 of the latch stopper can be retreated so that the latch bolt 200 can be moved to the right side in the figure, so that the latch bolt 200 can be immersed Structure.

The lever cam stopping jaw 107 and the latch stopper stopping jaw 106 of the dead bolt panic lever 101 are formed at positions corresponding to the rudder 404 of the lever cam and the ridge 204 of the latch stopper, As shown in Fig. 3, they are provided with a slight gap therebetween.

Further, in the present invention, like the ordinary motis, the outer lever 700 is provided at the center of the first rotating cam 401, and the panic lever 600 is fixed to the center of the second rotating cam 402 .

In the present invention as described above, the first rotation cam 401 rotates when the outer lever 700 is rotated without using an authentication means such as a password or a card. This rotation of the first rotation cam 401 causes the lever cam 400 to retract as shown in Fig. 4, so that the latch stopper 202 connected to the shaft bushing 203 is retracted, The protrusion 204 of the stopper and the protrusion 404 of the lever cam are brought into contact with the lever cam stopping jaw 107 and the latch stopper stopping jaw 106 of the deadbolt panic lever 101, respectively, State.

Therefore, since the latch bolt 200 can not be immersed in the state shown in FIG. 4, the latch bolt 200 together with the dead bolt 100 is held in a locked state while being stuck by the striker.

As shown in FIG. 5, when the second rotation cam 402 rotates, The projection 403 pushes the panic projection 105 on the other side of the dead bolt panic lever 101 in the clockwise direction in the drawing and the latch stopper stopper 106 and lever cam stopper 107 on the lower one side So that the projection 204 of the latch stopper and the projection 404 of the lever cam are slid to the right so that the latch bolt 200 and the latch stopper 202 are rotated, So that the body 300 is immersed in the striker.

The deadbolt key lever 102 rotates in the counterclockwise direction in the drawing by the rotation of the rod 108 above the deadbolt panic lever 101 in the element groove 109 of the deadbolt key lever 102, The deadbolt 100 is pivoted into the body 300 while the deadbolt 100 is pivoted to the right side in the drawing by rotating the deadbolt trebler 103 in the clockwise direction in the drawing.

5, the key cylinder 500 is rotated by the motor even in the case of authentication using a password or a card other than the panic lever 600. In this case, The seal 108 of the deadbolt panic lever 101 and the latch stopper stop 106 and the stopper stopper 107 and the panic protrusion 105 are operated as described above so that the latch bolt 200 The deadbolt key lever 102 and the deadbolt trever 103 pivoting by the key cylinder 500 immerse the dead bolt 100 into the body 300 It is of course in the same state as in Fig. 5, so that the door can be opened and closed.

As described above, according to the present invention, even if the outer lever 700 is rotated without opening the door in the state as shown in FIG. 5 through normal authentication in the locked state, the protrusion 204 of the latch stopper 202, The protrusion 404 of the cam 400 contacts the latch stop stop stop 106 of the dead bolt panic lever 101 and the stop stop 107 of the lever cam and can not move to the right side in the figure, All of the latch bolts 200 are kept locked and the door can not be opened.

In this state, even if the distance between the dead bolt 100 and the door frame is increased by a tool such as a nail dropper inserted between the dead bolt 100 and the door gap, The latch bolt 200 is still engaged with the striker, so that the door can not be opened so that it is possible to prevent an unauthorized intrusion of an outside person.

An example of the lever cam 400 used in the present invention is shown in Fig. As can be seen, the lever cam 400 receives the first rotation cam 401 and the second rotation cam 402 and slides along the rotation thereof, while a lever cam protrusion 404 And can be slidable or impossible to be locked in accordance with the rotation of the dead bolt panic lever 101 as indicated by a dotted line.

In addition, the structure of the deadbolt panic lever 101 used in the present invention is shown in Figs. 7 to 9 with different angles. FIG. 7 is a perspective view showing a dead bolt panic lever 101 in the direction shown in FIGS. 3 to 5, FIG. 8 is a perspective view as viewed from the opposite side, and FIG. 9 is a cross- And is a plan view as seen from the opposite side of the conveying direction.
