차량의 도어체커{DOOR CHECKER OF A VEHICLE}DOOR CHECKER OF A VEHICLE}

본 발명은 차량의 도어 개폐시 도어가 순간적으로 열리거나 닫히는 것을 방지할 수 있는 도어체커에 관한 것이다.The present invention relates to a door checker that can prevent the door from being opened or closed at the moment of opening and closing the door of the vehicle.

차량 도어가 적절히 감속되지 않으면, 도어 개폐시 원심력에 의해 도어가 차체와 강하게 충돌할 수 있다. 따라서, 탑승자에게 위험을 초래하거나, 도어 또는 차량이 충격에 의해 파손될 수 있다. 도어체커는 이러한 순간적인 도어의 여닫음을 방지하기 위해 도어의 여닫히는 속도를 감속시키는 댐퍼(damper)이다.If the vehicle door is not properly decelerated, the door may strongly collide with the vehicle body by the centrifugal force when the door is opened and closed. Therefore, it may cause danger to the occupant or the door or the vehicle may be damaged by the impact. The door checker is a damper that slows the opening and closing speed of the door to prevent the opening and closing of the door.

이하, 도 1 내지 도 3을 참조하여 종래 기술에 따른 도어체커를 상세히 설명한다.Hereinafter, the door checker according to the prior art will be described in detail with reference to FIGS. 1 to 3.

도 1은 통상적인 도어체커가 차량의 도어와 차체 사이에 장착된 상태를 도시한 사시도이다. 도시된 바와 같이, 도어체커(4)는 차량(1)의 차체(2)와 도어(3) 사이에서 도어(3)를 개폐하는 힌지장치로 사용된다. 1 is a perspective view illustrating a state in which a conventional door checker is mounted between a door and a vehicle body of a vehicle. As shown, the door checker 4 is used as a hinge device for opening and closing the door 3 between the vehicle body 2 and the door 3 of the vehicle 1.

도 2는 종래기술에 따른 도어체커를 도시한 사시도이고, 도 3은 도2의 도어체커가 차체 및 도어에 장착된 상태를 도시한 평면도이다. 도 2 및 도 3에 도시된 바와 같이, 도어체커(4)는 차체(2)에 부착되며 도어(3)가 수평방향으로 회전할 수 있도록 회전축(11)을 구비한 차체결합편(10)과; 상기 차체결합편(10)의 회전축(11)과 결합하며, 도어(3) 내측으로 연장되며, 그 길이방향을 따라 두께의 구배를 갖는 아암(20)과; 도어(3) 내측에 부착되며, 도어(3) 개폐시 아암(20) 상에서 그와 접촉하면서 이동하여 아암에 마찰력을 제공하기 위한 슬라이더(33)와 탄성체인 쿠션부재(34)로 이루어진 가압부재(32)를 갖는 감속부(30)와; 감속부(30)의 이동 범위를 제한하는 스토퍼(40)로 이루어진다. 감속부(30)는 가압부재(32)를 수용하는 케이스(31)를 포함하며, 쿠션부재(34)는 아암(20)의 두께 구배에 의해 슬라이더(33)가 밀리면, 슬라이더(33)에 의해 가압되어 탄성 변형함과 동시에 그 반력에 의한 탄성력을 다시 슬라이더(33)에 제공하여 슬라이더(33)와 아암(20) 사이에 마찰력을 증가시킨다. 쿠션부재(34)는 고무 등의 탄성체이다.2 is a perspective view illustrating a door checker according to the prior art, and FIG. 3 is a plan view illustrating a state in which the door checker of FIG. 2 is mounted to a vehicle body and a door. As shown in Figures 2 and 3, the door checker 4 is attached to the vehicle body 2 and the body coupling piece 10 having a rotating shaft 11 so that the door 3 can rotate in the horizontal direction; ; An arm (20) coupled to the rotating shaft (11) of the vehicle body coupling piece (10), extending into the door (3), and having a gradient of thickness along its longitudinal direction; Attached to the inside of the door (3), the pressing member consisting of a cushioning member (34) and a slider 33 for providing friction force to the arm by moving in contact with it on the arm (20) when the door (3) is opened and closed ( A deceleration section 30 having 32; The stopper 40 is configured to limit the moving range of the reduction unit 30. Reduction unit 30 includes a case 31 for receiving the pressing member 32, the cushion member 34, if the slider 33 is pushed by the thickness gradient of the arm 20, by the slider 33 At the same time it is pressurized and elastically deformed, the elastic force by the reaction force is again provided to the slider 33 to increase the friction force between the slider 33 and the arm 20. The cushion member 34 is an elastic body such as rubber.

쿠션부재(34)의 탄성에 의해 아암 (20)의 두께가 달라지더라도 아암(20)상에서 가압부재(32)가 이동할 수는 있다. 다만, 탄성력은 변형에 비례하므로 아암(20)의 두께가 두꺼운 곳에서 슬라이더(33)와 아암(20)의 마찰력이 커짐에 따라 저항이 커지고 크게 감속된다.Even if the thickness of the arm 20 is changed by the elasticity of the cushion member 34, the pressing member 32 can move on the arm 20. However, since the elastic force is proportional to the deformation, as the friction force between the slider 33 and the arm 20 increases in the place where the thickness of the arm 20 is thick, the resistance increases and is greatly reduced.

도 3에 도시된 바와 같이, 도어(3)가 열리면 도어(3)와 차체(2)의 접촉을 방지하기 위하여 도어가 아암(20)을 따라 회전축(11)으로부터 멀어지도록 이동한다. 이때, 차체(2)에 부착된 감속부(30)는 도어와 함께 아암(20)을 따라 이동한다. 아암(20)의 두께 구배는 감속부(30) 내부의 슬라이더(33)의 위치를 변화시키고, 슬라이더(33)의 위치에 따라 쿠션부재(34)의 탄성력이 변화한다. 즉, 아암(20)의 두께가 두꺼운 부분에서는 쿠션부재(34)가 슬라이더(33)를 미는 탄성력이 크기 때문에 슬라이더(33)와 아암(20)의 마찰력이 커져 도어가 비교적 많이 감속되고, 반대로, 아암(20)의 두께가 얇은 부분에서는 마찰력이 작아져 도어가 비교적 적게 감속된다. 즉, 슬라이더(33)와 아암(20)의 마찰력에 의해 도어(3)의 개폐속도가 조절될 수 있다.As shown in FIG. 3, when the door 3 is opened, the door moves along the arm 20 away from the rotating shaft 11 to prevent contact of the door 3 with the vehicle body 2. At this time, the reduction unit 30 attached to the vehicle body 2 moves along the arm 20 together with the door. The thickness gradient of the arm 20 changes the position of the slider 33 inside the deceleration part 30, and the elastic force of the cushion member 34 changes according to the position of the slider 33. That is, in the thick portion of the arm 20, since the cushion member 34 has a large elastic force pushing the slider 33, the friction force between the slider 33 and the arm 20 increases, so that the door is relatively slowed down. In the thin part of the arm 20, frictional force becomes small and the door is decelerated comparatively little. That is, the opening and closing speed of the door 3 can be adjusted by the frictional force of the slider 33 and the arm 20.

아암(20)의 두께는 양측에서 중앙으로 갈수록 증가하다가 중앙 부근에서는 여닫힘이 원활하도록 얇아지는 구배를 갖는 것이 바람직하다. 즉, 아암(20) 양측과 중앙부가 얇기 때문에, 쿠션부재(34)의 탄성력이 아암(20) 양측과 중앙부에서 약하고, 쿠션부재(34)가 가압하는 슬라이더(33)와 아암 간의 마찰력이 적다. 즉, 도어(3)는 쿠션부재(34)의 탄성력 구배가 낮은 곳에 위치되려고 하므로, 전술한 아암의 홈의 위치에 따라, 완전 개방, 중간 개방 또는 닫힘 상태의 세가지 위치에 도어가 위치하려는 경향을 갖는다. 따라서, 도어의 개폐시의 충격을 완충하면서도 사용자가 도어(3)를 편리하게 여닫을 수 있으며, 초기 위치에서 외력이 없다면 도어(3)가 쉽게 움직이지 않는다. The thickness of the arm 20 increases from both sides toward the center, and preferably has a gradient that becomes thin so that the opening and closing smoothly near the center. That is, since both sides and the center portion of the arm 20 are thin, the elastic force of the cushion member 34 is weak at both sides and the center portion of the arm 20, and the friction force between the slider 33 and the arm pressed by the cushion member 34 is small. That is, since the door 3 is intended to be positioned at a low elastic force gradient of the cushion member 34, the door 3 tends to be positioned at three positions of a fully open, intermediate open or closed state according to the position of the groove of the arm. Have Therefore, the user can conveniently open and close the door 3 while buffering the shock during opening and closing of the door, and the door 3 does not move easily if there is no external force at the initial position.

그러나, 상기와 같은 종래 기술에 따른 도어체커는 슬라이더(33)를 가압하는 쿠션부재(34)의 탄성력을 조절할 수 없기 때문에, 슬라이더(33) 또는 아암(20)의 마모나 변형에 의해 개폐력이 변화된 경우 이를 조절할 수 없는 문제점이 있다.However, since the door checker according to the prior art as described above cannot adjust the elastic force of the cushion member 34 for pressing the slider 33, the opening and closing force is increased due to the wear or deformation of the slider 33 or the arm 20. If changed, there is a problem that can not be adjusted.

또한 사용자가 원하는 개폐력으로 조절하지 못하는 문제점이 있다.In addition, there is a problem that the user can not adjust to the desired opening and closing force.

즉, 쿠션부재의 탄성력이 강한 상태에서 도어가 차체에 조립된 경우 도어 개폐를 위해 사용자가 많은 힘을 가하여야 하고, 쿠션부재의 탄성력이 약한 상태에서 도어(3)가 차체에 조립된 경우, 도어 개폐시 감속이 적어서, 도어 또는 차체에 충 격이 가해질 수 있다.That is, when the door is assembled to the vehicle body in a state where the cushion member is strong, the user must apply a lot of force to open and close the door, and when the door 3 is assembled to the vehicle body in the state where the cushion member is weak, the door When opening and closing, there is little deceleration, and the door or body may be impacted.

또한, 감속이 충분하지 않으면, 도어가 작은 외력에 의해서 초기위치에 정지하지 않고 요동칠 수 있는 문제점이 있다.In addition, if the deceleration is not sufficient, there is a problem that the door can swing without stopping to the initial position by a small external force.

또한, 개폐력을 조절하기 위해서는 도어를 차체에서 분리하고 도어체커를 도어로부터 분리하여 도어체커의 슬라이더 또는 쿠션부재를 교체하여야 하는 번거러움이 있었다.In addition, in order to control the opening and closing force, there was a need to remove the door from the body and the door checker from the door to replace the slider or the cushion member of the door checker.

상기와 같은 제반 문제점을 해결하기 위하여, 본 발명은 도어의 개폐력을 도어 또는 도어체커를 분해하지 않고 쉽게 조절할 수 있는 도어체커를 제공하는데 그 목적이 있다.In order to solve the above problems, an object of the present invention is to provide a door checker that can easily adjust the opening and closing force of the door without disassembling the door or the door checker.

상기와 같은 목적을 달성하기 위하여 본 발명에 따른 차량의 도어체커는 도어를 차체에 회전가능하게 결합시키는 차체결합편과; 상기 차체결합편과 결합하며, 도어 측으로 연장되는 아암과; 상기 도어 내측에 부착되며, 도어 개폐시 상기 아암 상에서 아암을 가압하면서 이동하여 상기 도어의 이동과 반대 방향의 마찰력을 제공하는 가압수단 및 상기 가압수단을 수용하는 케이스를 구비하는 감속수단과; 그리고 일단은 상기 가압수단을 가압하고 타단은 상기 도어 외측으로 노출되는 개폐속도조절수단을 포함한다.In order to achieve the above object, the door checker of the vehicle according to the present invention includes a vehicle body coupling piece for rotatably coupling the door to the vehicle body; An arm coupled to the vehicle body coupling piece and extending toward the door; A decelerating means attached to the inside of the door, the decelerating means including a pressurizing means for moving the pressurizing arm on the arm to open and close the door and providing a friction force in a direction opposite to the movement of the door; And one end pressurizes the pressing means and the other end includes opening and closing speed adjusting means exposed to the outside of the door.

상기 가압수단은 상기 아암과 접촉하는 슬라이더와 상기 슬라이더 상에 위치 되는 탄성체로 이루어진 쿠션부재를 포함하며, 상기 개폐속도조절수단은 일단은 도어 외측으로 노출되어 외부에서 그 위치를 조절할 수 있고, 타단은 상기 쿠션부재에 접하여 상기 쿠션부재를 가압하는 것이 바람직하다.The pressing means includes a cushion member comprising a slider in contact with the arm and an elastic body positioned on the slider, wherein the opening and closing speed adjusting means is exposed at the outside of the door to adjust its position from the outside. It is preferable to press the cushion member in contact with the cushion member.

상기 개폐속도조절수단은 드라이버로 그 위치가 조절될 수 있는 가압나사이거나, 손이나, 렌치로 너트의 위치를 조절할 수 있는 볼 스크류일 수 있다. 상기 볼 스크류의 축이 상기 케이스에 일단이 고정되며, 상기 너트는 상기 가압수단과 접하는 것이 바람직하다.The opening and closing speed adjusting means may be a pressure screw that can be adjusted in position with a driver, or a ball screw that can adjust the position of the nut with a hand or a wrench. One end of the shaft of the ball screw is fixed to the case, the nut is preferably in contact with the pressing means.

상기 아암은 상기 가압수단과 접하는 면이 양측과 중앙부가 얇은 두께의 구배를 갖는 것이 바람직하다.It is preferable that the arm has a gradient having a thin thickness at both sides and a central portion thereof in contact with the pressing means.

상기 감속수단의 이동 범위를 제한하기 위하여 상기 아암의 단부에 구비된 스토퍼를 추가로 포함하는 것이 바람직하다.It is preferable to further include a stopper provided at the end of the arm in order to limit the moving range of the deceleration means.

본 발명에 따르면, 도어의 개폐력이 변화하거나, 사용자가 원하는 도어의 개폐력이 설정된 개폐력과 다른 경우 사용자가 차량을 분해하지 않고도 편리하게 도어의 개폐력을 조절할 수 있는 효과가 있다.According to the present invention, when the opening and closing force of the door is changed, or the opening and closing force of the door desired by the user is different from the set opening and closing force, the user can conveniently adjust the opening and closing force of the door without disassembling the vehicle.

As shown, the door checker according to the present embodiment is attached to the vehicle body of the vehicle and the body engaging piece 110 having a rotating shaft 111 so that the door 103 can rotate in the horizontal direction; An arm (120) coupled to the rotating shaft (111) of the vehicle body coupling piece (110), extending into the door (103), and having a gradient of thickness in its longitudinal direction; A case attached to the inside of the door 103 and moving on the arm 120 when the door 103 is opened and closed and receiving a pressing means 132 and a pressing means 132 to provide frictional force according to the thickness gradient of the arm 120 ( A reduction unit 130 including 131; A stopper 140 for limiting a movement range of the reduction unit 130; As a means for adjusting the opening and closing speed includes a pressing screw 135 for pressing the pressing means 132 to deform.

가압수단(132)은 아암(120)과 접촉하는 슬라이더(133)와 슬라이더(133)와 접촉하는 탄성체인 쿠션부재(134)로 이루어지며, 가압나사(135)는 쿠션부재(134)를 가압한다.The pressing means 132 is composed of a slider 133 in contact with the arm 120 and a cushion member 134 which is an elastic body in contact with the slider 133, and the pressure screw 135 presses the cushion member 134. .

슬라이더(133)는 아암(120)과 접촉하면서 아암(120)을 따라 이동하며, 슬라이더(133) 및 쿠션부재(134)는 케이스(131)에 수용된다. 가압나사(135)의 가압정도에 따라 쿠션부재(134)의 변형 정도가 달라지며 쿠션부재(134)의 변형정도에 따라 슬라이더(133)와 아암(120) 간의 마찰력을 변화시킨다.The slider 133 moves along the arm 120 while in contact with the arm 120, and the slider 133 and the cushion member 134 are accommodated in the case 131. The degree of deformation of the cushion member 134 varies according to the pressure of the pressure screw 135, and the friction force between the slider 133 and the arm 120 is changed according to the degree of deformation of the cushion member 134.

케이스(131) 및 도어(103)에는 가압나사(135)가 삽입될 수 있도록 나사공이 형성된다. 쿠션부재(134)는 고무와 같은 탄성재료로서 탄성의 법칙(Hooke's law) 을 따르며, 탄성계수는 일정하다. 슬라이더(133)는 쿠션부재(134)보다 강성이 높은 물질로 이루어지는 것이 바람직하다.Screw holes are formed in the case 131 and the door 103 so that the pressure screw 135 can be inserted therein. The cushion member 134 is an elastic material, such as rubber, in accordance with Hooke's law, and the elastic modulus is constant. The slider 133 is preferably made of a material having a higher rigidity than the cushion member 134.

도 5 및 도 6은 도 4의 도어체커를 이용하여 도어 개폐력을 조절하는 과정을 도시한 단면 사시도이다.5 and 6 are cross-sectional perspective views illustrating a process of adjusting the door opening and closing force by using the door checker of FIG.

도 5에 도시된 바와 같이, 가압나사(135)가 조여지지 않으면, 쿠션부재(134)가 차지하는 부피가 크다. 부피는 쿠션부재(134)가 케이스(131) 및 슬라이더(133)에 접촉하는 면에 의해 결정된다.As shown in FIG. 5, when the pressure screw 135 is not tightened, the volume occupied by the cushion member 134 is large. The volume is determined by the surface on which the cushion member 134 contacts the case 131 and the slider 133.

가압나사(135)를 조이면 쿠션부재(134)가 차지하는 부피가 줄어든다. 즉, 가압나사(135)를 조인 만큼 쿠션부재(134) 내부의 응력이 증가하고 케이스의 크기는 일정하므로, 쿠션부재(134)가 슬라이더(133)를 미는 힘이 증가한다. 따라서, 슬라이더(133)와 아암(120) 사이의 마찰력이 증가한다. When the pressure screw 135 is tightened, the volume occupied by the cushion member 134 is reduced. That is, as the pressure screw 135 is tightened, the stress inside the cushion member 134 increases and the size of the case is constant, so that the force that the cushion member 134 pushes the slider 133 increases. Thus, the frictional force between the slider 133 and the arm 120 increases.

슬라이더(133)와 아암(120) 사이의 마찰력이 증가하면, 도어(103)의 개폐력이 커지게 되므로, 도어체커(130)를 분리하지 않고서도 도어 외부에서 드라이버 등을 이용하여 가압나사(135)를 조이거나 풀어서 편리하게 도어의 개폐속도를 조절할 수 있으며, 사용자가 원하는 정도로 개폐력을 설정할 수 있다.When the friction force between the slider 133 and the arm 120 increases, the opening and closing force of the door 103 increases, so that the pressure screw 135 using a driver or the like from the outside of the door without removing the door checker 130. You can adjust the opening and closing speed of the door conveniently by tightening or releasing), and you can set the opening and closing force as much as you want.
