본 발명은 차량 도어의 열림 방지 도어래치구조에 관한 것으로서, 차량 충돌시 역관성에 의해 도어가 열리는 것을 방지하고, 도어래치를 사용하는 모든 차량의 밸런스웨이트에 적용이 가능한 차량 도어의 열림 방지 도어래치구조에 관한 것이다.The present invention relates to an opening preventing door latch structure of a vehicle door, which prevents the door from being opened due to inertia during a vehicle collision, and is capable of being applied to a balance weight of all vehicles using the door latch. It is about.

도 1a은 종래 기술에 따른 도어 아웃사이드 핸들 구조를 나타낸 도면이고, 도 1b는 종래 기술에 따른 도어 아웃사이드 핸들 구조의 단면을 나타낸 도면이다.Figure 1a is a view showing a door outside handle structure according to the prior art, Figure 1b is a view showing a cross section of the door outside handle structure according to the prior art.

도 1a 및 도 1b에 도시된 바와 같이, 종래 도어 아웃사이드 핸들 구조는 도어패널(28) 내부에 핸들 베이스판(12)이 설치되고, 핸들 베이스판(12)에 도어 아웃사이드 핸들(10)의 젖힘 작동과 함께 회전하는 레버(14)가 핀축(16)에 의해 고정되는 구성이다. As shown in FIGS. 1A and 1B, in the conventional door outside handle structure, the handle base plate 12 is installed inside the door panel 28, and the door outside handle 10 is mounted on the handle base plate 12. The lever 14 that rotates with the flipping operation is fixed by the pin shaft 16.

또한, 레버(14)의 하단부는 도어잠금장치의 래치와 로드 또는 케이블(18)에 의해 연결되고, 레버(14)의 상단부에는 소정의 부피 및 무게를 갖는 밸런스웨이트(20)가 일체로 성형되고, 핀축(16)에는 리턴스프링(26)이 삽입되어 그 단부는 도어 아웃사이드 핸들(10)의 내면에 고정되고, 타단은 밸런스웨이트(20)의 안쪽면에 밀착되어 걸어진 상태가 된다.In addition, the lower end of the lever 14 is connected by a latch and a rod or a cable 18 of the door lock device, the balance weight 20 having a predetermined volume and weight is integrally formed on the upper end of the lever 14. The return shaft 26 is inserted into the pin shaft 16, and an end thereof is fixed to the inner surface of the door outside handle 10, and the other end is in close contact with the inner surface of the balance weight 20.

즉, 도어 아웃사이드 핸들(10)을 당기면, 레버(14)의 하단이 당김방향으로 각운동하게 되고, 동시에 레버(14)의 하단부에 연결된 로드 또는 케이블(18)이 당겨지면서 도어잠금장치의 래치가 해제되어 도어가 개방된다.That is, when the door outside handle 10 is pulled, the lower end of the lever 14 is angularly moved in the pulling direction, and at the same time, the rod or cable 18 connected to the lower end of the lever 14 is pulled to latch the door locking device. Is released and the door is opened.

여기서, 밸런스웨이트(20)는 차량의 측면 충돌시 차량의 속도 변화에 대해 도어 아웃사이드 핸들 및 그 연결부품들에 관성 하중이 발생되는데, 이때 도어 아웃사이드 핸들이 당겨져 도어 래치가 해제되는 것을 방지하는 역할을 한다. 즉, 밸런스웨이트는 도어 아웃사이드 핸들의 작동방향과 반대의 관성 하중을 발생시켜 도어 아웃사이드 핸들의 작동을 억제시키는 것이다.Here, the balance weight 20 generates an inertial load on the door outside handle and its connecting parts in response to the speed change of the vehicle during a side collision of the vehicle, wherein the door outside handle is pulled to prevent the door latch from being released. Play a role. That is, the balance weight generates an inertial load opposite to the operation direction of the door outside handle to suppress the operation of the door outside handle.

그러나, 종래 도어 아웃사이드 핸들 구조는 밸런스웨이트의 중량이 무거우면정관성에 의해 문이 열리는 것을 방지할 수 있지만 역관성에 의해 문이 열리는 경우가 발생되고, 반대로 밸런스웨이트의 중량이 가벼우면 역관성에 의해 도어가 열리는 것을 방지할 수 있지만 정관성에 의해 문이 열리는 것을 막을 수 없게 된다는 문제가 발생되었다.However, the conventional door outside handle structure prevents the door from being opened by inertia if the weight of the balance weight is heavy, but the door is opened by inertia. On the contrary, if the weight of the balance weight is light, the door is caused by inertia. It can prevent the opening of the door, but due to the inertia can not prevent the door from opening.

특히, 충돌시 도어열림을 방지하기 위한 밸런스웨이트는 여러 차례의 충돌 시험을 통해 밸런스웨이트의 중량을 적절하게 튜닝해야 하는데, 이로 인해 불편함이 발생되고 중량 및 원가가 증대된다는 문제가 발생되었다.In particular, the balance weight to prevent the door opening in the collision should be properly tuned to the weight of the balance weight through a number of collision tests, which causes inconvenience and increases the weight and cost.

본 발명의 목적은 전술된 종래기술의 문제점을 해결하기 위한 것으로서, 차량 충돌시 역관성에 의해 도어가 열리는 것을 방지하여 차량 충돌에 의한 도어 개방으로 탑승자가 상해를 입지 않도록 하는 차량 도어의 열림 방지 도어래치구조를 제공하는 것이다.An object of the present invention is to solve the above-mentioned problems of the prior art, preventing the door from being opened due to inertia in the event of a vehicle collision prevents the opening of the door of the vehicle door to prevent the occupant from injury by opening the door by the vehicle collision To provide a structure.

도 2 내지 도 4b에 도시된 바와 같이, 본 발명은 차량의 측면 충돌시 도어 아웃사이드 핸들 케이블(200)과 연동되는 회동레버(210)의 회전을 위한 밸런스웨이 트유닛(100)이 도어래치패널(310)에 설치되되, 상기 밸런스웨이트유닛(100)은 브라켓몸체(110)와, 브라켓몸체(110)의 상면에 회동 가능하게 설치되는 밸런스웨이트편(120) 및, 상기 밸런스웨이트편(120)의 회동축(123)에 탄성 설치되는 리턴스프링(130)을 포함하는 구조이다.As shown in Figures 2 to 4b, the present invention is a door latch panel with a balance weight unit 100 for the rotation of the rotation lever 210 is interlocked with the door outside handle cable 200 in the side impact of the vehicle Is installed on the 310, the balance weight unit 100 is the bracket body 110, the balance weight piece 120 is installed to be rotatable on the upper surface of the bracket body 110, and the balance weight piece 120 The structure includes a return spring 130 that is elastically installed on the rotation shaft 123.

구체적으로, 차량의 도어래치(300)에는 차량의 측면 충돌시 도어 아웃사이드 핸들 케이블(200)의 작동에 의한 회동레버(210)의 회전을 방지하기 위한 밸런스웨이트유닛(100)이 설치된다. Specifically, the door latch 300 of the vehicle is provided with a balance weight unit 100 for preventing the rotation of the rotation lever 210 by the operation of the door outside handle cable 200 during the side impact of the vehicle.

이러한 밸런스웨이트유닛(100)은 차량의 측면 충돌시 상기 브라켓몸체(110)에 안착되어 있던 밸런스웨이트편(120)을 돌출시켜 상기 회동레버(210)의 회전이 단속되도록 함으로써, 차량 충돌에 의한 관성으로 인해 차량 도어가 개방되는 것을 방지하는 것이다.The balance weight unit 100 protrudes the balance weight piece 120 seated on the bracket body 110 during a side collision of the vehicle so that rotation of the rotation lever 210 is interrupted, thereby causing inertia due to vehicle collision. This is to prevent the vehicle door from opening.

여기서, 상기 브라켓몸체(110)는 상기 도어 아웃사이드 핸들 케이블(200)에 연동되는 회동레버(210)의 회전 경로상에 인접하게 배치되도록 도어래치패널(310)에 고정 설치되는데, 상기 브라켓몸체(110)의 도어래치패널(310) 상의 고정 위치는 차량의 측면 충돌에 의해 상기 밸런스웨이트편(120)이 돌출되는 경우 상기 돌출된 밸런스웨이트편(120)이 상기 회동레버(210)의 회전을 막을 수 있을 정도의 인접 위치이다.Here, the bracket body 110 is fixedly installed on the door latch panel 310 to be disposed adjacent to the rotation path of the rotation lever 210 that is linked to the door outside handle cable 200, the bracket body ( The fixed position on the door latch panel 310 of 110 may prevent the protruding balance weight piece 120 from rotating by the rotation lever 210 when the balance weight piece 120 protrudes due to a side collision of the vehicle. Adjacent enough position.

특히, 상기 브라켓몸체(110)에는 상기 밸런스웨이트편(120)의 일부가 안착되는 안착홈(111)이 형성되고, 상기 브라켓몸체(110)의 일측 상면에는 후술하는 밸런스웨이트편(120)의 회동축(123)이 구속되는 한 쌍의 끼움부재(112)가 형성된다. In particular, the bracket body 110 is formed with a seating groove 111 in which a portion of the balance weight piece 120 is seated, and on one side surface of the bracket body 110, the balance weight piece 120 to be described later. A pair of fitting members 112 on which the coaxial 123 is restrained are formed.

상기 밸런스웨이트편(120)은 차량 측면 충돌시 상기 회동레버(210)에 접촉되어 회동레버(210)의 회전을 직접적으로 방지하는 바, 이를 위해 상기 밸런스웨이트편(120)은 플레이트 형상의 작동방지부(121)와 상기 작동방지부(121)에 수직연결되어 상기 브라켓몸체(110)의 안착홈(111)에 안착되는 안착부(122)로 구성되고, 상기 밸런스웨이트편(120)의 일단부에는 리턴스프링(130)을 통해 상기 브라켓몸체(110)의 끼움부재(112)에 힌지연결되는 회동축(123)이 형성된다.The balance weight piece 120 is in contact with the rotation lever 210 when the vehicle side collision directly prevents the rotation of the rotation lever 210 bar for this purpose, the balance weight piece 120 prevents the operation of the plate shape It is composed of a seating portion 122 that is vertically connected to the portion 121 and the operation preventing portion 121 to be seated in the seating groove 111 of the bracket body 110, one end of the balance weight piece 120 The rotation shaft 123 is hinged to the fitting member 112 of the bracket body 110 through the return spring 130 is formed.

즉, 상기 밸런스웨이트편(120)은 평소 리턴스프링(130)에 의해 상기 브라켓몸체(110)의 안착홈(111)에 안착되어 있으나, 차량 측면 충돌이 발생되면 상기 밸런스웨이트편(120)은 차량 충돌에 의한 관성에 의해 상기 회동레버(210)의 회전경로 방향으로 이동되어 상기 회동레버(210)의 회전을 막음에 따라, 차량 충돌에 따른 도어의 개방을 방지할 수 있는 것이다.That is, the balance weight piece 120 is usually seated in the seating groove 111 of the bracket body 110 by the return spring 130, but if a vehicle side collision occurs, the balance weight piece 120 is a vehicle. As the inertia caused by the collision is moved in the direction of the rotation path of the pivoting lever 210, the rotation of the pivoting lever 210 is prevented, thereby preventing the opening of the door due to the vehicle collision.

상술한 바와 같이, 본 발명의 차량 도어의 열림 방지 도어래치구조의 경우 차량 충돌시 역관성에 의해 도어가 열리는 것을 방지하고, 도어래치를 사용하는 모든 차량의 밸런스웨이트에 적용 가능하다는 장점이 있다.
