It is a kind of security component.

On the other hand, when the lock and unlock (unlock) process of the door by the latch bolt 30 will be described in more detail, the latch bolt 30 is approximately the interior case 10 so as to be parallel to the dead bolt (20). The inner space is spaced apart from the inside by a predetermined distance, and the holding lever 40, in particular, the second holder 44 is reciprocated by a predetermined distance in the horizontal direction from the lower side inside the interior case 10. In this case, a part of the latch bolt 30 also protrudes outside the interior case 10, and a part of the latch bolt 30 protruding outside the interior case 10 is the door frame 100. The door is locked or unlocked (unlocked) by an operation of being inserted into or detached from the second insertion portion 102b.

Here, both the dead bolt 20 and the latch bolt 30 are inserted into or separated from the first inserting portion 102a and the second inserting portion 102b respectively formed in the door frame 100. The same is true in terms of locking and unlocking (unlocking) the door, but as described above, the latch bolt 30 is not operated electrically but only by an external force provided by a user, whereas the dead The bolt 20 may be operated by an external force provided by an electric force or an external force provided by a user. Here, the process in which the dead bolt 20 is operated by an external force provided by the user is specifically related to the technical features of the interior-side electronic door lock assembly 1 according to the present invention, which will be described later. Shall be.

As described above, the dead bolt 20 receives an external force provided by an electric force and is reciprocated for a predetermined distance in a horizontal direction in a horizontal direction in the interior case 10. As such, a preferred embodiment of the indoor side electronic door lock assembly 1 according to the present invention in order to enable the reciprocating movement of the dead bolt 20, the rotation center of any one point inside the interior case 10 The action lever 50 is disposed so as to be rotated by a predetermined angle with respect to the rotation shaft C2 having a rotational contact with the dead bolt 20 to move the dead bolt 20 in one of the left and right horizontal directions. It may include.

The dead bolt 20 has a locking groove 25 is formed so that the action lever 50 is rotated in contact with the dead bolt (20). The locking groove 25 is formed on the rotation path of the action lever 50. As such, the action lever 50 is disposed on the dead bolt 20 so that the dead bolt 20 is caught by the action lever 50 when the action lever 50 is rotated by a predetermined angle. It is moved in the horizontal direction.

The action lever 50 may be rotated by receiving a rotational force from the lock driving unit 60 to be described later, and of course, a predetermined rotational force may be applied by the first holder 42 of the holding lever 40. It can be rotated by receiving. Here, when the first holder 42 transmits a rotational force to the action lever 50, it is natural that the dead bolt 20 is also moved in the horizontal direction.

As shown in FIGS. 6A to 7B, an action gear 52 having a gear tooth 53 formed therein is disposed on the outer rim of the action lever 50 such that another gear is engaged with the outer edge portion thereof. As shown in FIG. 8, the action gear 52 has a center hollow portion 52 ′ formed to be inserted into the rotation shaft C2 of the action lever 50.

Here, the hollow portion 52 'of the action gear 52 such that a predetermined gap is formed between the inner circumferential surface of the hollow portion 52' of the action gear 52 and the outer circumferential surface of the rotation shaft C2 of the action lever 50. ) The inner diameter is larger than the outer diameter of the rotation shaft C2 of the action lever 50.

On the other hand, the action gear 52 receives a rotational force from the lock drive unit 60 to be described later is rotated on the rotation axis (C2) of the action lever 50 and at the same time from the lock drive unit 60 to the action lever 50 The first locking end 54 protrudes toward the rotation shaft C2 of the action lever 50 so as to be caught by at least some of the outer circumferential surfaces of the rotation shaft C2 of the action lever 50. ) Is formed. The first engaging end 54 may be formed / arranged to be spaced apart at two locations so as to maintain an interval of approximately 180 ° with respect to the center of the inner circumferential surface of the action gear 52.

The action lever 50 is rotated in conjunction with the action gear 52 when the first engaging end 54 of the action gear 52 rotated by the lock driving unit 60 is engaged. The second engaging end 55 is formed on the rotation shaft C2. Here, the second locking end 55 is formed at both ends 55a and 55b of the free moving groove 57 formed to be recessed to a predetermined depth in the direction of the rotation axis C2 which is the center of rotation of the action lever 50. Corresponding. As described above, the free moving groove 57 is a rotation shaft C2 of the action lever 50 so that each of the first engaging ends 54 provided at two positions can be inserted and moved when the action gear 52 is rotated. It is formed in two places. The length of each of the free moving grooves 57 may be formed to face each other so as to have an outer circumferential surface length of 100 ° based on the center of the rotation axis C2 of the action lever 50.

Here, it should be noted that the first engaging end 54 of the action gear 52 is not always caught by the second engaging end 55 formed on the rotation shaft C2 of the action lever 50. . That is, when the action gear 52 is rotated by receiving the rotational force from the lock driving unit 60, the first engaging end 54 has the second engaging end 55 by the length of the free moving groove 57. It will rotate alone without interference.

In this way, the electronic door lock assembly 1 according to the present invention, the action gear 52 to the rotation axis (C2) of the action lever 50 by a predetermined distance, that is, the length of the free moving groove 57, alone Rotating prevents the external force from being transmitted backward from the action lever 50 to the lock driver 60 when the action lever 50 is rotated by the inner door handle, thereby preventing damage to the lock driver 60. You can prevent it.

In more detail, if the open operation button is arranged on the indoor side of the product configuration, the user presses the open operation button to exit the indoor side from the indoor side. This is a step for unlocking (unlocking) the door that is locked by the dead bolt 20. When the open operation button is activated, the lock driving unit 60 is operated to release the dead bolt 20. The rotational force for unlocking is transmitted to the action lever 50.

On the other hand, when there is no opening operation button of the product configuration, the user immediately rotates the inner door handle 210 by using the holding lever 40 to release the dead bolt 20 to the door ( Can be unlocked).

However, in general, as shown in FIG. 6A, when looking at a specific position of the action lever 50 when the lock of the door is completed using the dead bolt 20, the first catching end 54 ) Is caught in the second locking end 55a corresponding to one end of the free moving groove. In this state, when the user rotates the inner door handle 210 as described above, the first holder 42 of the holding lever 40 transmits a rotational force to the action lever 50 and provides a rotational force. The received action lever 50 is rotated while transmitting the rotational force as it is to the lock drive unit 60 may damage the lock drive unit 60.

As such, in order to prevent the lock driving unit 60 from being damaged, the indoor side electronic door lock assembly 1 according to the present invention has the free moving groove 57 in which the action gear 52 can be rotated alone. .

That is, when the indoor side electronic door lock assembly 1 according to the present invention switches the door to a locked state by using the dead bolt 20, the lock driving unit 60 is predetermined by a controller not shown. The second latch corresponding to the other end of the free moving groove 57 is operated by the first locking end 54 which is engaged with the second locking end 55 a corresponding to one end of the free moving groove 57 by operating for a time. Control to move to the locking end (55b). That is, the first locking end 54 is operated by operating the lock driving unit 60 in advance to prevent the control unit from damaging the lock driving unit 60 according to the external force transmission through the inner door handle 210 of the user. When the action lever 50 is unexpectedly rotated, the second engaging end corresponding to the other end of the free moving groove 57 so as to secure a non-interference section in which only the action lever 50 is rotated alone. 55b). However, since the action lever 50 is actually fixed, the first locking end 54 is in a stopped state. When the lock driving unit 60 is operated, the action gear 52 is rotated to relatively rotate the first lever. The locking end 54 is engaged with the second locking end 55a corresponding to one end of the free moving groove 57, and then the second locking end corresponding to the other end of the free moving groove 57 is formed. 55b) is caught on the side.

In this state, even when the user rotates the inner door handle 210 without following the above-described order, the first engaging end 54 of the action lever 50 is in contact with the action gear 52. Since it is caught by the second locking end 55b corresponding to the other end of the free moving groove 57 which does not interfere, only the action lever 50 is driven by the first holder 42. As it is rotated alone by the length of), the external force is not transmitted back to the lock driving unit 60.

On the other hand, when the door is unlocked (unlocked) by moving the dead bolt 20 inside the interior case 10 as described above, only the action lever 50 by the inner door handle 210 By rotating, the first locking end 54 is locked to the second locking end 55a corresponding to one end of the free moving groove 57 again.

In this case, when the door is detected to be closed by the user moving to the door frame 100 side (components for detecting the door unlock detection unit for detecting the movement of the sensor bolt 90 to be described later) Reference numeral 83 of 2) operates the lock driving unit 60 to move the dead bolt 20 in the opposite direction, and the first locking end 54 corresponds to one end of the free moving groove 57. Since the second locking end 55a is in a locked state, the action lever 50 may be immediately rotated in the opposite direction, and thus the door may be switched to the locked state by the dead bolt 20.

The operation process of the electronic door lock assembly 1 according to the present invention for preventing the damage of the lock drive unit 60 as described above is rather useful when the user panic occurs indoors. That is, when the panic occurs, the user should quickly escape from the indoor side to the outdoor side. If the open operation button is embarrassed, the inner door handle 210 may be immediately rotated without pressing it or the inner door handle. In most cases, the lock 210 is rotated with excessive force, and the lock driving unit 60 is frequently damaged.

On the other hand, a preferred embodiment of the electronic door lock assembly 1 according to the present invention further includes a lock driving unit 60 for providing a predetermined rotational force to rotate the action lever 50.

Referring to the configuration of the lock drive unit 60 in more detail, as shown in Figures 1 and 2, one end of the rotating shaft (C4) is coupled by the hinge (C4) and the other end is hinged (C4) A motor gear box 61 installed to rotate about the one end rotation shaft C4, a drive motor (not shown) installed and electrically operated in the motor gear box 61, and installed on the rotation shaft of the drive motor. And a motor gear 63 which is rotated.

In this case, the action gear 52 and the motor gear 63 are arranged to be engaged with each other, so that the action gear 52 rotates when the motor gear 63 is rotated during the operation of the drive motor. It is to rotate the 50 in one direction.

Meanwhile, the latch bolt 30 is rotated about the one end hinge coupling portion C3 having one end coupled to the inside of the interior case 10 and the other end hinged by an external force. It is connected to the rotating leg 70 is disposed, it is installed so as to be exposed to the outside of the interior case 10 in conjunction with the rotation of the rotating leg 70. As described above, a part of the latch bolt 30 exposed to the outside of the interior case 10 is locked or unlocked (unlocked) by an operation of being inserted into or detached from the second insertion portion 102b. It is natural to make).

As such, a preferred embodiment of the electronic door lock assembly 1 according to the present invention for enabling the reciprocating movement of the latch bolt 30 may include rotational operation of the outer door handle and the inner door handle 210. The second holder 44 is installed in contact with the other end of the rotation leg 70 of the holding lever 40 which is rotated in conjunction with each other.

When the second holder 44 is rotated, the rotation leg 70 rotates the other end about the hinged one end portion C3 and rotates the latch bolt 30 of the interior case 10. It moves in the horizontal direction to the right in the drawing. Then, a part of the latch bolt 30 that has been exposed to the outside of the interior case 10 is inserted into the interior case 10 while being separated from the second insertion portion 102b to release the door. (Unlock) will be done.

Here, when the user rotates the inner door handle 210, the first holder 42 and the second holder 44 simultaneously rotate the action lever 50 and the rotation leg 70, and the dead The bolt 20 and the latch bolt 30 are unlocked at the same time in a locked state.

On the other hand, when the user rotates the outer door handle, the first holder 42 is not rotated but only the second holder 44 is rotated so that only the rotation leg 70 is rotated so as to interlock with the latch bolt 30. Only the bay is unlocked.

However, when the user rotates the outer door handle, the first holder 42 is configured not to rotate, but it is not a big problem. However, when the user rotates the inner door handle 210, the user may have a panic phenomenon. And the first holder 42 as well as the second holder 44 are rotated so that the users can quickly escape from the indoor side to the outdoor side. In this case, the lock driving unit for moving the dead bolt 20 60 is connected to the action lever 50, there was a problem that the panic operation is not smooth. In addition, the first holder 42 transmits a rotational force, while the lock driving unit 60 is in a stopped state when it is not operating. There was a problem of this deterioration.

In order to solve such a problem at one time, a preferred embodiment of the electronic door lock assembly 1 according to the present invention is the motor gear box 61 of the lock drive unit 60 of the interior case 10 It is installed so as to rotate a predetermined angle inside.

In more detail, as shown in FIG. 1, one end of the motor gear box 61 is coupled to the inside of the interior case 10 by a hinge C4, and the other end thereof is applied when an external force is applied. The hinge C4 is disposed to be rotated by a predetermined angle.

An elastic member 65 may be disposed in the interior case 10 to elastically support the outer surface of the rotated motor gear box 61 to return to the original position when the external force is removed.

Here, the action gear 52 and the motor gear may be formed on the outer circumferential surface of the holding lever 40 and the motor gear box 61 when a panic phenomenon occurs between a user and indoor residents (hereinafter referred to as "users"). A panic operation unit 110 capable of releasing the connection of 63 is formed.

The panic operation unit 110 has a function of allowing the user to quickly escape by unlocking the door without any malfunction when the user rotates the inner handle door during the configuration of the electronic door lock assembly 1 according to the present invention. To perform.

More specifically, the panic actuator 110 includes a protruding rib 46 formed on an outer circumferential surface of the holding lever 40 and protruding toward the motor gear box 61. In addition, the panic operation unit 110 is formed to be in contact with the outer circumferential surface of the holding lever 40 on one side of the motor gear box 61, the holding lever corresponding to one side of the protruding rib 46 It further includes a rounding portion 64 formed to be rounded so as to be disposed in contact with the outer circumferential surface of the 40 and only a predetermined gap is formed. That is, the gap formed between the rounding part 64 and the holding lever 40 is smaller than the protruding thickness of the protruding rib 46.

The protruding ribs 46 formed on the holding levers 40 are rotated by the holding levers 40 when the user rotates the inner door handle 210 in the room side. The motor gear box 61 is pushed outwardly by a predetermined angle with respect to the one end of the hinge C4 coupled to the gap between the box 61 and the gap formed by the outer circumferential surface of the holding lever 40.

As such, when the other end is pushed by a predetermined angle around the one end of which the motor gear box 61 is entirely hinged (C4), the bite (matching) between the action gear 52 and the motor gear 63 is released. You will be disconnected from each other. Therefore, the angle at which the other end of the motor gear box 61 is pushed about the hinge C4 should be about the angle at which the bite between the action gear 52 and the motor gear 63 is released. That is, the other end of the motor gear box 61 is preferably pushed about 3 ° or more about the hinge (C4).

In other words, the protruding thickness of the protruding rib 46 is the motor gear when the protruding rib 46 enters the gap formed between the rounding portion 64 and the outer circumferential surface of the holding lever 40. Preferably, the other end of the box 61 is formed to a thickness such that the other end portion is pushed about 3 ° or more about the one portion.

Here, if the user continues to rotate the inner door handle 210, when the holding lever 40 is rotated in conjunction with the continuous rotation of the inner door handle 210, the rotational force is the dead bolt 20 and The dead bolt 20 and the latch bolt 30 are transferred to the latch bolt 30 to be unlocked at the same time (ie, unlocked) so that users can open the door and escape quickly. .

On the other hand, the dead lock detection unit 81 and the dead unlock detection unit 82 for detecting the locking and unlocking state of the door by the dead bolt 20 is disposed on the movement path of the dead bolt 20, respectively.
