That is, the spring member 20 is provided to ensure the closing operation in the closing region, and the damping member 50 is provided to damp this closing operation.
한편, 스프링 부재(20)와 댐핑 부재(50)는 인접하여 서로 배열각(θ2)을 이루도록 배치될 수 있다. Meanwhile, the spring member 20 and the damping member 50 may be disposed adjacent to each other to form an arrangement angle θ2.
즉, 스프링 부재(20)와 댐핑 부재(50)는 멀티링크 힌지(1000)의 링크들 사이 또는 바텀 레버(100)와 링크 사이 또는 탑 레버(200)와 링크 사이에 인접하게 배치될 수 있다. 바람직하게는, 스프링 부재(20) 및 댐핑 부재(50)는 탑 레버(200)와 제3 링크(500) 사이에 배열각(θ2)을 이루며 인접하게 배치될 수 있다.That is, the spring member 20 and the damping member 50 may be disposed adjacent to each other between the links of the multi-link hinge 1000 or between the bottom lever 100 and a link or between the top lever 200 and a link. Preferably, the spring member 20 and the damping member 50 may be disposed adjacently between the top lever 200 and the third link 500 forming an arrangement angle θ2.
따라서, 멀티링크 힌지(1000)는 스프링 부재(20)에 의한 닫힘 기능 및 댐핑 부재(50)에 의한 감쇠 기능이 컴팩트하게 구현될 수 있다. 또한, 스프링 부재(20)와 댐핑 부재(50)의 인접 배치 구조로 인하여, 스프링 부재(20)와 댐핑 부재(50) 사이의 상대적인 움직임이 감소하기 때문에 요구되는 설치 공간이 감소하게 된다. Accordingly, the multi-link hinge 1000 can compactly implement a closing function by the spring member 20 and a damping function by the damping member 50 . In addition, due to the adjacent arrangement structure of the spring member 20 and the damping member 50, the relative movement between the spring member 20 and the damping member 50 is reduced, so the required installation space is reduced.
보다 구체적으로, 댐핑 부재(50)는 선형 댐퍼로서, 상기 스프링 부재(20)와 이격된 위치에서 일측단이 상기 제3 링크(500)에 연결되고, 타측단이 상기 탑 레버(200)에 연결될 수 있다.More specifically, the damping member 50 is a linear damper, and one end is connected to the third link 500 and the other end is connected to the top lever 200 at a position spaced apart from the spring member 20. can

스프링 부재(20)는 일측단이 스프링 레버(30)에 구비된 축에 연결되고, 타측단이 상기 탑 레버(200)에 연결될 수 있다.One end of the spring member 20 may be connected to a shaft provided in the spring lever 30 and the other end may be connected to the top lever 200 .
스프링 부재(20)는 코일 스프링으로 형태의 스프링(21)을 포함한다. 이때, 스프링(21)은 압축 스프링으로 형성될 수 있다. 물론, 스프링(21)을 인장 스프링으로 형성하는 것 또는 스프링 부재(20)를 위해 하나 이상의 스프링(21)을 이용하는 것 또한 가능하다.The spring member 20 includes a spring 21 in the form of a coil spring. At this time, the spring 21 may be formed as a compression spring. Of course, it is also possible to form the spring 21 as a tension spring or to use more than one spring 21 for the spring member 20 .
스프링 레버(30)는 상기 제3 링크(500)에 회전 가능하게 장착될 수 있다. 또한, 스프링 레버(30)에는 캠 부재(40)와 접촉하며 회전하는 롤러(31)가 설치되어 있다.The spring lever 30 may be rotatably mounted on the third link 500 . In addition, a roller 31 that rotates while contacting the cam member 40 is installed on the spring lever 30 .
캠 부재(40)는 2개의 축을 통해 상기 제1 링크(300)에 연결될 수 있으며, 스프링 레버(30)의 롤러(31)가 캠 부재(40)와 접촉 회전함에 따라 스프링 부재(20)의 스프링(21)이 긴장되거나 완화된다.The cam member 40 may be connected to the first link 300 through two shafts, and as the roller 31 of the spring lever 30 rotates in contact with the cam member 40, the spring of the spring member 20 (21) is tense or relaxed.
즉, 스프링 부재(20)는 스프링 레버(30) 및 롤러(31)를 통해 지지되고, 롤러(31)는 주행면을 따라 캠 부재(40) 상에서 회전한다. 이러한 구조를 통해, 멀티링크 힌지(1000)의 인출각도(θ1)가 대략 0° 내지 30° 범위인 닫힘 구역에서, 스프링 부재(20)는 효과적으로 탑 레버(200)를 닫힘 방향으로 편향시킬 수 있게 된다.That is, the spring member 20 is supported via the spring lever 30 and the roller 31, and the roller 31 rotates on the cam member 40 along the running surface. Through this structure, in the closing region where the withdrawal angle θ1 of the multi-link hinge 1000 is in the range of approximately 0 ° to 30 °, the spring member 20 can effectively bias the top lever 200 in the closing direction. do.
도 7은 본 발명의 일 실시예에 따른 멀티링크 힌지의 인출각도에 따른 스프링 부재와 댐퍼 부재의 배열각을 나타내는 표이고, 도 8은 본 발명의 일 실시예에 따른 멀티링크 힌지의 인출각도에 따른 스프링 부재와 댐퍼 부재의 배열각을 나타내는 그래프이다.7 is a table showing an arrangement angle of a spring member and a damper member according to a withdrawal angle of a multi-link hinge according to an embodiment of the present invention, and FIG. 8 is a table showing an arrangement angle of a multi-link hinge according to an embodiment of the present invention. It is a graph showing the arrangement angle of the spring member and the damper member according to
도 4 내지 도 8을 참조하면, 멀티링크 힌지(1000)는 닫힘 상태, 즉 인출각도(θ1)가 0°인 상태에서 완전 열림 상태, 즉 인출각도(θ1)가 대략 105°인 상태까지 작동하게 된다.4 to 8, the multi-link hinge 1000 operates from a closed state, that is, a state in which the withdrawal angle θ1 is 0 ° to a fully open state, that is, a state in which the withdrawal angle θ1 is approximately 105 ° do.
멀티링크 힌지(1000)의 열림 또는 닫힘 과정에서, 롤러(31)와 캠 부재(40)를 통해 스프링 부재(20)에 작용하는 압축 하중은 인출각도(θ1)가 30° 내지 60°, 바람직하게는 40° 내지 50°에서 최대가 된다.In the process of opening or closing the multi-link hinge 1000, the compressive load acting on the spring member 20 through the roller 31 and the cam member 40 has a withdrawal angle θ1 of 30 ° to 60 °, preferably is maximum between 40° and 50°.
이때, 본 발명은 스프링 부재(20)의 하중이 최대가 되는 멀티링크 힌지(1000)의 인출각도(θ1) 30° 내지 60° 사이의 범위에서 스프링 부재(20)와 댐핑 부재(50)가 이루는 배열각(θ2)이 최소가 되도록 구성될 수 있다.At this time, the present invention is the spring member 20 and the damping member 50 in the range between 30 ° and 60 ° of the withdrawal angle (θ1) of the multi-link hinge 1000 at which the load of the spring member 20 is maximum. The arrangement angle θ2 may be configured to be minimized.
즉, 스프링 부재(20)의 하중이 최대가 되는 지점에서, 스프링 부재(20)와 댐핑 부재(50)가 이루는 배열각(θ2)이 최소가 됨에 따라 댐핑 부재(50)에 의한 감쇠력 전달 효율이 최대가 된다. 이로써, 인출각도(θ1)가 30° 내지 60°를 벗어날 때 스프링 부재(20)에 의한 탄성력에 의해 도어가 세게 닫히거나 열리는 것을 미연에 방지할 수 있게 된다.That is, as the arrangement angle θ2 between the spring member 20 and the damping member 50 is minimized at the point where the load of the spring member 20 is maximized, the damping force transmission efficiency by the damping member 50 increases. becomes the maximum Accordingly, it is possible to prevent the door from being forcefully closed or opened by the elastic force of the spring member 20 when the withdrawal angle θ1 is out of the range of 30° to 60°.
도 7 및 도 8을 참조하면, 스프링 부재(20)와 댐핑 부재(50)는 실질적으로 멀티링크 힌지(1000)의 인출영역 전체에 걸쳐 서로 배열각(θ2)을 이루며 정렬될 수 있고, 구체적으로 5° 이상 15° 이하로 정렬될 수 있다. 따라서 스프링 부재(20)와 댐핑 부재(50)는 서로 가깝게 인접하여 배치될 수 있고, 멀티링크 힌지(1000)는 컴팩트한 구조로 구성될 수 있다. Referring to FIGS. 7 and 8 , the spring member 20 and the damping member 50 may be aligned at an angle θ2 with each other substantially throughout the pull-out area of the multi-link hinge 1000, specifically It can be aligned more than 5° and less than 15°. Accordingly, the spring member 20 and the damping member 50 may be disposed close to each other, and the multi-link hinge 1000 may have a compact structure.
또한, 스프링 부재(20)와 댐핑 부재(50)의 배열각(θ2)은 멀티링크 힌지(1000)의 전체 인출영역에 걸쳐 완만한 포물선 그래프를 나타내도록 구성될 수 있다. 이로써, 도어의 열림 또는 닫힘 과정에서 스프링 부재(20)의 탄성력에 따른 편향 움직임이 발생하게 됨에도 배열각(θ2)이 멀티링크 힌지(1000)의 전체 인출영역에 걸쳐 완만한 포물선 그래프를 나타내도록 제어되어 도어의 작동이 부드럽게 이루어질 수 있고 사용자의 작동 감성이 향상될 수 있다.In addition, the arrangement angle θ2 of the spring member 20 and the damping member 50 may be configured to show a gentle parabolic graph over the entire drawing-out area of the multi-link hinge 1000 . As a result, even though deflection movement occurs according to the elastic force of the spring member 20 during the opening or closing process of the door, the arrangement angle θ2 is controlled to show a gentle parabolic graph over the entire withdrawal area of the multi-link hinge 1000 Thus, the door can be operated smoothly and the user's operating sensibility can be improved.
도 4 내지 도 6을 참조하여, 멀티링크 힌지(1000)의 열림 또는 닫힘 과정을 구체적으로 설명하면 다음과 같다.Referring to FIGS. 4 to 6 , a process of opening or closing the multi-link hinge 1000 will be described in detail as follows.
도 4에서, 멀티링크 힌지(1000)는 닫힘 상태, 즉 인출각도(θ1)가 0° 인 상태이고, 이때 스프링 부재(20)와 댐핑 부재(50)의 배열각(θ2)은 대략 13.5°를 이루게 된다. 또한, 롤러(31)과 캠 부재(40)는 아직 접촉되지 않는 상태로서 스프링 부재(20)에 캠 부재(40)에 의한 압축 하중이 작용하지 않게 된다.In FIG. 4 , the multi-link hinge 1000 is in a closed state, that is, a state in which the drawing angle θ1 is 0°, and at this time, the arrangement angle θ2 of the spring member 20 and the damping member 50 is approximately 13.5°. will be achieved In addition, the roller 31 and the cam member 40 are not yet in contact with each other, and the compression load by the cam member 40 does not act on the spring member 20 .
