It should be included within the protection scope of the claims. The sensitive member indicated in this embodiment is an optocoupler.

The driving connection filler hole 225 has a diameter greater than the diameter of the driving connection pillar 24, the base side concave groove 214 has a length greater than the driving connection side wall 224, and the driving connection filler 24 is connected to the driving base ( 21 ) and the driving upper cover 23 are fixed, leaving a movable space in the driving connection part 22 .

When assembling, the driving connection part 22 is assembled to the driving base 21, and at this time, a part of the elastic body 25 is accommodated in the base concave groove 212, and the other part and the base protrusion 211 are driven together in the driving connection groove. housed within (222); The entire drive connecting portion 22 is located within the lap of the left and right base side sides 213 so that it cannot but move vertically in the guide direction of the base side side 213; The lap from which the drive connection side wall 224 is drawn out from the base side concave groove 214 is drawn into the sensitive member 7 .

The driving connecting filler 24 passes through the driving upper cover hole 231, the driving connecting pillar hole 225, and the base connecting pillar hole 215 of the driving upper cover 23, and then connecting it with the case (A), The entire clutch driving mechanism 2 is integrally formed, and at this time, under the role of tension of the elastic body 25 , the driving connection part 22 has a force away from the square rod driving mechanism 1 all the way. Since the drive connecting lower wall 223 is in contact with the lever mechanism 3 , the drive connecting portion 22 has a force in the pressing direction of the lever mechanism 3 all the way.

The driving pillar 221 , which is the other side of the driving connection part 22 , is introduced into the clutch hole 1234 of the clutch member 123 and is connected to the clutch member 123 . When the driving connection part 22 is moved, the clutch member 123 induces the clutch protrusion 1233 to rotate about the axis. When the drive connecting portion 22 is driven to move upward, it induces the clutch member 123 to move upward, so that the clutch member inner wall 1232 comes into contact with the side edge of the gear shaft 13; When the driving connection part 22 is driven to move downward, the clutch member 123 is guided to move downward, so that the clutch member inner wall 1232 moves away from the gear shaft 13 .

As shown in FIGS. 8 and 9 , the lever mechanism 3 includes a lever part 31 with both sides symmetrical, a lever base 32 fixedly connected to the case A, and a lever cap 33 . A hole coordinate is installed at the symmetrical center of the lever part 31 and used to accommodate the protrusion of the lever base 32 . The lever cap 33 is used to prevent the lever part 3 and the lever base 32 from being separated. After being connected, the lever part 31 serves as a lever centering on the lever base 32 , that is, using the lever base 32 as a rotation axis.

Both sides of the lever part 31 are provided with a lever protrusion 311 , and the lever protrusion 311 is in direct contact with the side of the case (A), but the lever base 32 serves as a lever with respect to the lever part 31 . Therefore, the lever protrusions 311 on both sides cannot be in contact with both sides of the case A at the same time.

Both sides of the lever part 31 are in contact with the electric driving pillar 41 and the driving connection lower wall 223 , respectively, so that the electric driving pillar 41 presses the lever part protrusion 311 of the lever part 31 . At this time, the lever protrusion 311, which is the other side in contact with the drive connection lower wall 223, moves away from the side surface of the case (A); On the other hand, when the electric driving pillar 41 does not press the lever protrusion 311 , the driving connection part 22 approaches the side of the case A under the natural tension action of the elastic part 25 . That is, when the driving connection lower wall 223 presses the lever protrusion 311 , at this time, the lever protrusion 311 in contact with one side of the electric driving pillar 41 moves away from the side of the case A.

Hereinafter, the operation process of the driving device according to the present invention will be described in more detail.

As shown in Figs. 1 to 2 and Figs. 10 to 11, in the driving device according to the present invention, the lock thereof mainly forms two states: an open state and a closed state.

In the open state, the latch bolt mechanism 6 is drawn out of the case side side A. At this time, the electric driving pillar 41 is located in a fixed position, and the driving connection part 22 is in a state to approach the side of the case A under the natural tension action of the elastic part 25, and the driving connection lower wall 223 is By pressing one side of the lever protrusion 311, the pressed lever protrusion 311 is in contact with the side of the case (A); The clutch member inner wall 1232 is separated from the side wall of the gear shaft 13 by the driving connection part 22 of the clutch member 123 , and the side wall 1231 of the clutch member does not come into contact with the movable insertion member pillar 142 .

At this time, since the clutch member sidewall 1231 does not contact the movable insert member pillar 142, even if the square rod rotates to induce the top insert 11 or the bottom insert 15 to rotate, the clutch part 12 cannot induce the rotation of the gear shaft 13, and further, cannot induce the dead bolt gear 51 meshing therewith to move, so that the dead bolt mechanism achieves a fixed position.

When trying to crack the door, the electric drive mechanism 4 receives an electromagnetic signal, drives and moves the electric drive pillar 41, and presses the lever protrusion 311 on the side in contact with the case ( A) By making the side side contact, the lever part projection 311 on the other side moves away from the side side of the case (A).

At this time, the drive connection lower wall 223 is compressed so that the drive connection part 22 moves upward as a whole, and the elastic part 25 is compressed so that the drive connection side wall 224 starts to come into contact with the sensitive member 7 , , the driving pillar 221 moves upward to induce rotation of the clutch member 123 , and the clutch member inner wall 1232 contacts the gear shaft 13 .

The external force rotates the square rod and induces the top insertion member 11 or the bottom insertion member 15 to rotate, and furthermore, the top insertion member clamping plate 112 or the bottom insertion member support plate 152 is a clutch. The part 12 is induced to rotate, and the clutch member sidewall 1231 contacts the movable insert member pillar 142, thereby inducing the rotation of the movable insert member 14, and the movable insert member pillar 142 is a gear projection. Contact 133 to induce rotation of the gear shaft 13, the gear 132 induces the dead bolt gear 51 to move, and finally, the dead bolt mechanism 5 moves out of the case side wall S. induce it to be drawn out.

At this time, the sensitive member 7 sends a signal to the electric drive mechanism 4, and the electric drive mechanism 4 drives the electric drive pillar 41 to move in the reverse direction to recover the fixed position, and the elastic part 25 ) under the action of natural tension, the drive connection part 22 moves downward, and the lever part protrusion 311 on one side of the drive connection lower wall 223 in contact with it is pressed until it contacts the side side of the case (A). and; The driving pillar 221 moves downward along the driving connecting portion 22 , and guides the clutch member 123 away from the movable insertion member pillar 142 and the sidewall of the gear shaft 13 .

Accordingly, the door-breaking operation is completed.

As described above, the lever mechanism 3 is pressed through the electric drive mechanism 4 , and the clutch drive mechanism 2 is guided to lead the clutch member 123 to move. Of course, it is conceivable that the same function can still be implemented even if the clutch member 123 is extended to use the fixed end of the clutch member 123 as an axis, and the extended part is pushed or led. Do not repeat explanations.

The above has been described in detail the specific implementation manner of the present invention. Those skilled in the art may understand that various modifications and improvements may be made to the present invention without departing from the principles of the present invention, and the modifications and improvements are also included in the protection scope of the claims of the present invention.
