이들 도면에 도시된 바와 같이, 종래기술에 의한 감속기어(100)는 모터(미도시)가 내장되는 케이스(101)와 상기 케이스(101)에 회전가능하게 설치되고 상기 모터에 동력적으로 연결되는 회전축(102)과 상기 회전축(102)과 함께 회전가능하게 그 회전축(102)에 결합되는 구동기어(103)를 구비한다.As shown in these figures, the reduction gear 100 according to the prior art is installed in a case 101 and a case 101 is a motor (not shown) is built in the rotatably and the motor is connected to the motor It includes a rotary shaft 102 and a drive gear 103 coupled to the rotary shaft 102 rotatably together with the rotary shaft 102.

상기 회전축(102)은 비원형 단면부를 구비하고, 상기 구동기어(103)는 상기 회전축(102)의 비원형 단면부에 결합되는 비원형단면홈(103a)을 가짐으로써, 상기 회전축(102)과 구동기어(103)가 함께 회전될 수 있게 된다.The rotary shaft 102 has a non-circular cross-section, and the drive gear 103 has a non-circular cross-sectional groove 103a coupled to the non-circular cross-section of the rotary shaft 102, thereby the rotation shaft 102 and The drive gear 103 can be rotated together.

이러한 구성을 가지는 감속기어(100)는 도 2에 잘 도시된 바와 같이 디지털 도어록에 채용된다.The reduction gear 100 having such a configuration is employed in the digital door lock as shown in FIG.

즉, 종래기술에 의한 디지털 도어록은, 상기 감속기어(100)와, 그 감속기어(100)의 구동기어(103)에 맞물리는 피동기어와, 상기 피동기어에 동력적으로 연결됨으로써 도어의 개폐를 가능하게 하는 래치블럭(105)과, 상기 래치블럭(105)에 상기 도어의 개폐를 위한 개폐력을 인가하는 작동부재(106)와, 상기 피동기어에 동력적으로 연결되고, 상기 도어의 록킹 및 언록킹을 가능하게 하는 데드블럭(107)을 구비한다.That is, the digital door lock according to the related art is connected to the reduction gear 100, the drive gear 103 of the reduction gear 100 and the driven gear and the driven gear to be dynamically connected to the opening and closing of the door. And a latch block 105 for enabling the operation, an operation member 106 for applying an opening and closing force to the latch block 105 for opening and closing the door, and a power supply to the driven gear, for locking the door and And a dead block 107 to enable unlocking.

이러한 구성을 가지는 디지털 도어록은, 도 3에 잘 도시된 바와 같이, 상기 조작부재에 사용자에 의한 개폐력이 전달되지 않은 상태에서, 상기 모터의 구동에 의해 상기 데드블럭(107)을 인출시킴으로써, 상기 도어의 록킹을 가능하게 한다. 여기서, 상기 개폐력은 상기 조작부재에 결합되는 손잡이(108)를 통해 발생되는 것이다. As shown in FIG. 3, the digital door lock having such a configuration is obtained by drawing the dead block 107 by driving of the motor while the opening and closing force of the user is not transmitted to the operation member. Enable locking of the door. Here, the opening and closing force is generated through the handle 108 is coupled to the operation member.

이와 같이 도어의 록킹이 이루어지는 과정에서, 도 4에 도시된 바와 같이, 사용자가 상기 래치블럭(105)을 인입시키는 힘을 상기 작동부재(106)에 가하게 되면, 도 4의 실선으로 도시된 바와 같이, 상기 조작부재는 시계방향으로 회전되고, 그 조작부재에 연결되는 매개블럭(109)은 반시계방향으로 회전되며, 그 매개블럭(109)에 연결되는 피동기어는 시계방향으로 회전되며, 그 피동기어에 연결되는 구동기어(103)는 반시계방향으로 회전이 이루어지게 된다. As described above, in the process of locking the door, if the user applies the force to pull the latch block 105 to the operating member 106, as shown by the solid line of FIG. , The operating member is rotated in the clockwise direction, the intermediate block 109 connected to the operating member is rotated counterclockwise, the driven gear connected to the intermediate block 109 is rotated in the clockwise direction, the driven The drive gear 103 connected to the gear is made to rotate in the counterclockwise direction.

그러나, 상기 데드블럭(107)이 모터에 의한 회전력에 의해 인출되는 과정에서는 도 4의 점선으로 도시된 바와 같이, 상기 조작부재에 가해지는 강제 회전력(역방향 회전력)에 의해 회전되는 회전방향과 반대방향으로 회전이 이루어지도록, 상기 모터에 의한 전기적인 신호에 의한 상기 회전축(102)의 회전력이 상기 구동기어(103)에 전달되게 된다.However, in the process in which the dead block 107 is drawn out by the rotational force by the motor, as shown by the dotted line in FIG. 4, the direction opposite to the rotational direction rotated by the forced rotational force (reverse rotational force) applied to the operation member is shown. The rotational force of the rotating shaft 102 is transmitted to the drive gear 103 by the electrical signal by the motor so that the rotation is performed.

결국, 상기 모터의 회전축(102)은, 상기 구동기어(103)와 함께 시계방향으로 회전이 이루어지게 되고(도 4 확대부분 참조), 이와는 반대로 상기 조작부재에 가해진 역방향 회전력에 의해 상기 구동기어(103)가 반시계방향으로 회전됨으로써, 상기 모터와 구동기어(103)의 손상 및 상기 피동기어의 손상을 초래하게 된다.As a result, the rotating shaft 102 of the motor is rotated in the clockwise direction together with the driving gear 103 (see enlarged part of FIG. 4), on the contrary, the driving gear ( As the 103 is rotated counterclockwise, damage to the motor and the drive gear 103 and damage to the driven gear are caused.

Between the body is a spring 14 having an elasticity disposed in the space between the rotary shaft 12 and the drive gear (13).

그리고, 상기 스프링(14)은 그 일단(14a)이 상기 회전축(12)에 형성된 삽입홈(12a)에 삽입됨으로써 그 회전축(12)에 동력적으로 연결되고, 그 타단(14b)이 상기 구동기어(13)에 형성된 삽입홈(13a)에 삽입됨으로써 그 구동기어(13)에 동력적으로 연결된다.

한편, 도 8을 참조하여 본 실시예의 장점을 종래기술과 비교하여 설명하면 다음과 같다.On the other hand, with reference to Figure 8 will be described the advantages of the present embodiment compared to the prior art.

즉, 종래기술에 의하면 도 8의 상측에 잘 도시된 바와 같이, 모터에 가해지는 전기적인 신호에 의해 모터의 회전축(102)과 구동기어(103)가 점선으로 도시된 바와 같이 회전하게 되고, 이와 같이 회전하는 도중에 피동기어(104)에 강제회전력이 가해지게 되면, 그 피동기어(104)에 가해지는 역방향 회전력에 의해 상기 구동기어(103)는 도 8의 실선으로 도시된 바와 같이 회전이 이루어지게 된다. That is, according to the prior art, as shown in the upper side of FIG. 8, the rotating shaft 102 and the drive gear 103 of the motor rotate as shown by the dotted lines by the electric signal applied to the motor. When a forced rotational force is applied to the driven gear 104 during the rotation, the drive gear 103 is rotated as shown by the solid line of FIG. 8 by the reverse rotational force applied to the driven gear 104. do.

이와 같이, 상기 모터에 가해지는 전기적 신호에 의한 회전력과 상기 피동기어(104)에 가해지는 역방향 회전력이 동시에 상기 구동기어(103)에 가해지게 되면, 상기 역방향 회전력이 상기 모터에 의한 회전력을 압도하면서 그 모터의 회전축(102)의 회전과 구동기어(103)의 회전이 반대방향으로 이루어지게 된다. 결국, 종래기술에 의하면, 이러한 동작으로 인하여 모터와 구동기어(103)의 손상 및 파손을 초래하게 되고 상기 피동기어(104) 또한 손상이 쉽게 이루어지는 단점이 있다.As such, when the rotational force by the electrical signal applied to the motor and the reverse rotational force applied to the driven gear 104 are applied to the drive gear 103 at the same time, the reverse rotational force overwhelms the rotational force by the motor The rotation of the rotating shaft 102 of the motor and the rotation of the drive gear 103 are made in the opposite direction. As a result, according to the related art, such an operation causes damage and breakage of the motor and the drive gear 103, and the driven gear 104 also has the disadvantage of being easily damaged.

Even if the rotation shaft 12 is rotated in the space between the rotation shaft 12 and the drive gear 13 while overcoming the elastic force of the spring 14, the rotation shaft 12 is shown as a virtual line As described above, the rotation is normally performed based on an electrical signal applied to the motor separately from the forced rotation of the drive gear 13.

이와 같이, 본 발명은 상기 구동기어(13)가 원래 회전하고자 하는 방향과 반대방향으로 회전되는 경우에도 상기 회전축(12)이 원래의 회전방향으로 회전할 수 있도록 구성됨으로써, 상기 모터와 구동기어(13)가 상기 피동기어(20)에 가해지는 역방향 회전력에 의해 손상 또는 파손되는 것을 방지할 수 있는 장점을 가진다.As such, the present invention is configured such that the rotation shaft 12 can rotate in the original rotation direction even when the drive gear 13 is rotated in a direction opposite to the direction in which the drive gear 13 is originally intended to rotate. 13) has an advantage that can be prevented from being damaged or broken by the reverse rotational force applied to the driven gear (20).
