Referring to FIGS. 2 and 3, a clutch connecting and driving assembly 100 of a lever-type door lock according to an embodiment of the present invention is installed inside a mounting hole formed at the door D. The mounting plate 30 is mounted on the front end of the latch assembly 20 and the latch assembly 20 is installed with the latch bolt 21 drawn out to one side of the door D.

On the other hand, the latch assembly 20 is coupled to the mounting module 50, which has, for example, a circular outer circumferential surface corresponding to the shape of the mounting hole drilled in the door D.

4 and 5, the mounting module 50 is provided with a motor unit 10, a cam ring member 60, a first shaft 41, a second shaft 42, Member (not assigned a drawing number).

A first shaft 41 and a second shaft 42 are installed so as to pass through the center of the mounting module 50. [ The motor unit 10 is mounted on the upper portion of the mounting module 50 and the motor unit 10 provides driving force for rotating the camming member 60 installed in the mounting module 50.

The cam ring member 60 is formed with a circular inner circumferential surface 64 and a portion of the inner circumferential surface 64 is formed with a cam surface 63 having a diameter larger than that of the inner circumferential surface 64. A part of the outer circumferential surface of the cam ring member 60 ) Are formed.

The external gear 61 of the cam ring member 60 is gear-connected to the motor unit 10 and is rotated by the driving force of the motor unit 10. [ At this time, the cam ring member 60 is installed on the outer side of the tip end 42a of the second shaft 42. A part of the end portion of the first shaft 41 is inserted into the front end portion 42a of the second shaft 42 and the first shaft 41 and the second shaft 42 can be connected by a clutch pin member have. The clutch pin member is also moved up and down so as to penetrate both the first and second shafts 41, 42 by rotation of the cam ring member 60 (this will be described in more detail below).

In addition, the PCB (P) is mounted inside the mounting module 50, and the cover plate 51 is mounted so as to cover the open outside when the internal components are installed. At this time, the first shaft 41 protrudes from the through hole 51h of the cover plate 51.

The first shaft 41, for example, is connected to the handle shaft, and the second shaft 42 is connected to the rotating body of the latch assembly 20, for example. When the handle shaft is rotated in the state where the first shaft 41 and the second shaft 42 are connected to each other (the clutch-on (0n) state), the shafts 41 and 42 are connected So that the driving force is transmitted to the rotating body of the latch assembly 20, thereby forming the unlocked state of the latch.

The motor unit 10 is constructed in such a manner that the first case 10a and the second case 10b are coupled to each other and a second gear 13 is attached to the driving gear M1 of the motor M And the first gear 11 is connected to the second gear 13. As shown in Fig. These gears can be applied in different forms depending on the reduction ratio. The first gear 11 is formed with a rotary shaft 11a fixed to one side and the worm gear 12 is mounted with the spring 11s inserted into the rotary shaft 11a. At this time, a spline is formed on the rotating shaft 11a, and the worm gear 12 is mounted so as to cooperate with the spline.

Accordingly, the first gear 11 rotates and the cam member 60 can be rotated through the worm gear 12 as the motor M is driven.

5, the clutch pin member of the present invention is formed with a lead-out hole 42h on the upper side of the tip end portion 42a of the second shaft 42, and an engagement groove 42a is formed on the inner bottom surface of the tip end portion 42a. h) are formed. A first pin (71) is inserted into the drawing hole (42h), and a second pin (72) is placed below the first pin (71). It goes without saying that, in some cases, these pins 71 and 72 other than the plurality of pins may be applied in the form of a single clutch pin member integrally formed.

On the other hand, a mounting groove 41s of the spring S is formed on the first shaft 41, and the first shaft 41 is fixed to the second shaft (not shown) with the pin member 72 being elastically supported by the spring S. [ 42 of the second shaft 42 in the state of being connected to the second shaft 42. [ The first pin 71 is installed in a protruded state through the drawing hole 42h of the second shaft 42 and the second pin 72 is fixed to the lower portion of the first pin 71 by the spring S, As shown in Fig. So that the first pin (71) is positioned supported by the second pin (72).

Referring to FIG. 6, a camming member 60 is rotatably disposed inside the mounting module 50 outside the distal end portion 42a of the second shaft 42. As shown in FIG. The worm gear 12 connected to the first gear 11 of the motor unit 10 is connected to the external gear 61 formed on the outer circumferential surface of the cam ring member 60 so that the worm gear 12 is rotated by the rotation of the motor M Is rotated outside the distal end portion 42a of the second shaft 42. [ At this time, a recognition piece 62 protrudes from the outer circumferential surface of the cam ring member 60. The recognition piece 62 is positioned by the first sensor P1 and the second sensor P2 formed on the PCB P Is detected. For example, when the cam ring member 60 rotates, the recognition member 62 located at the first sensor P1 moves to the second sensor P2, so that the control unit can recognize the operation position of the cam ring member 60 .

7A and 7B, the inner circumferential surface 64 of the cam ring member 60 provided inside the mounting module 50 is formed to have a size corresponding to the outer circumferential surface of the distal end portion 42a of the second shaft 42. At this time, the cam surface 63 is formed on the upper side of the inner circumferential surface 64 of the cam ring member 60 with a radius larger than the outer circumference of the tip end portion 42a. That is, the cam surface 63 is formed so as to have such a margin that the first pin 71 drawn out from the outer peripheral surface of the second shaft 42 is not pressed.

Accordingly, when the worm gear 12 rotates the camming member 60 by the rotation of the motor M, the camming member 60 rotates from the position of FIG. 7A to the position of FIG. 7B. At this time, the cam surface 63 of the cam ring member 60 is moved clockwise, so that the first pin 71 in a pulled-out state descends along the inner circumferential surface 64 of the cam ring member 60. The first pin 71 can lower the second pin 72 and set the clutch on state of the first shaft 41 and the second shaft 42. [

Referring to FIGS. 8A and 8B, FIG. 8A shows a positional state of the first pin 71 and the second pin 72 in FIG. 7A. In the state of Fig. 8A, the first pin 71 is in the drawn state (original position) and is located within the tip end 42a of the second shaft 42, but is not interfered (inserted) into the first shaft 41 . The second pin 72 is also positioned inside the first shaft 41 and is not interfered with the leading end 42a of the second shaft 42. [ In other words, even if the first shaft 41 is rotated by rotating the pull shaft in this state, the driving force is not transmitted to the second shaft 42 (clutch off state).

8B, when the cam surface 60 rotates and the cam surface 32 is moved so that the inner circumferential surface 64 having a smaller diameter than the cam surface 32 presses the first pin 71, the first pin 71 And descends along the second pin 72 located at the lower portion of the first pin 71 as well. At this time, the tip of the first pin (71) is located inside the second shaft (42) and the end of the first pin (71) is located inside the first shaft (41). The second pin 72 in a state of being lowered against the elastic force is positioned in the engagement groove 42h of the second shaft 42 and the rest of the second pin 72 is positioned in the first shaft 41. [ Therefore, the first shaft 41 and the second shaft 42 are connected to each other at their ends. That is, in this state, when the handle shaft is rotated to rotate the first shaft 41, the second shaft 42 is also rotated so that the latch assembly 20 can be driven through the driving force (clutch-on state).

On the contrary, when the cam ring member 60 is returned to its original state, the second pin 72 pushes up the first pin 71 by the resilient force, thereby achieving the clutch off state as shown in FIGS. 7A and 8A.

9A and 9B, according to the present invention, even if the camming member 60 is rotated in either the left or right direction, the inner circumferential surface 64 having a reduced diameter than the cam surface 63 presses the first pin 71, It is unnecessary to make a structural change according to the change of the number of left and right, thereby providing convenience of use.

10A and 10B, the present invention is characterized in that the driving shaft of the camshaft 60 is interrupted in the middle of the operation due to the engagement of the shaft with the shaft, and the reaction force transmitted due to the stop of the camshaft member 60 To the motor (10), thereby leading to damage to the motor (M).

Specifically, the present invention is provided with a disconnection member in the motor section (10). The connection releasing member provided in the present invention has a rotation shaft 11a extending by a predetermined length to one side of the first gear 11 and a spring 11s inserted therein. And the worm gear 12 elastically supported by the spring 11s is mounted.

The worm gear 12 is connected to the spline of the rotary shaft 11a of the first gear 11 and rotated together with the first gear 11 when the motor M is operated. In this case, when the camming member 60 can not be rotated due to the engagement of the handle shaft or the like, the worm gear 12 continues to rotate but does not rotate the engaged camming member 60. In this situation, the worm gear 12 moves along the external gear 61 of the cam ring member 60 in the leftward direction (moves to a kind of rack and pinion operation) while overcoming the elastic force of the spring 11s as shown in FIG. 10B.

When the worm gear 12 rotates in the state where the cam ring member 60 is stopped as described above, it moves in the left direction of the rotation shaft 11a of the first gear 11 (that is, moves along the gear of the external gear) When the worm gear 12 is moved to the leftmost side of the rotary shaft 11a, the worm gear 12 is short-circuited to the gear connection by the gear 61 of the cam member 60, Can be prevented. Also, at this time, the controller may recognize the jam, and the function of stopping the driving of the motor M may be included.

As described above, the present invention can prevent the motor M from being continuously driven in a state in which the camming member 60 is stopped due to a jamming or the like during operation, resulting in a load on the device leading to device failure.

While the present invention has been particularly shown and described with reference to the particular embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
