The present invention relates to a door checker device for a vehicle that can be prevented from closing again.

일반적으로, 자동차 도어에는 도어의 열림 각을 제어하고 최대 열림량을 고정시켜주는 체커가 설치되어 있다.In general, a car door is provided with checkers that control the opening angle of the door and fix the maximum opening amount.

자동차에 마련된 도어는 차체 사이드 부에 회동하여 개폐 가능하도록 도어 힌지로 장착 체결되어 사용자의 의해 개폐되며, 이러한 도어 힌지와 함께 도어가 회동하여 열릴 경우 어느 한도 이상으로 열리지 않도록 그 개도를 일정범위로 제한하는 도어 체커가 구비되는 것이다.The door provided in the vehicle is mounted and fastened by the door hinge to be opened and closed by rotating on the side of the vehicle body, and is opened and closed by the user. When the door is rotated and opened together with the door hinge, the opening degree is limited to a certain range. The door checker is provided.

도 1에서 보듯이, 차체 바디에 고정되는 체커 브래킷(1)과, 그 일단이 상기 체커 브래킷(1)에 고정되고 그 타단은 도어에 결합되어 굴곡부(2)을 갖는 길다란 막대 형상의 체커암(3)과, 이 체커암(3)의 타측단에 설치되어 도어의 내측에 수용되는 스토퍼(4)와 도어 판넬에 고정되어 상기 체커암(3)에 결합되며 도어가 개폐될 경우 이 체커암(3)을 따라 이동되면서 상기 체커암(3)의 굴곡부(2)에 걸려 도어의 개도 각을 느끼도록 하는 체커부(5)로 구성된다.As shown in Figure 1, a checker bracket (1) fixed to the body of the body, one end thereof is fixed to the checker bracket (1) and the other end is coupled to the door is a long rod-shaped checker arm having a bent portion (2) 3) and a stopper (4) installed at the other end of the checker arm (3) and fixed to the stopper (4) and the door panel which are accommodated inside the door and coupled to the checker arm (3), and the checker arm ( It is composed of a checker portion (5) to move along the 3) to catch the bent portion (2) of the checker arm (3) to feel the opening angle of the door.

또한, 상기 체커부(5)는 도 2에서 보듯이 이 체커부(5)의 외면을 감싸는 케이싱(6)과, 케이싱(6) 내부의 중심부에 설치되는 롤러(8)와, 이 롤러(8) 양측에 설치되어, 상기 굴곡부(2)를 지나갈때 상기 롤러(8)가 걸리어 그 절도감을 느낄 수 있게 그 양측에 항상 롤러(8)를 밀고 있는 스프링(7)이 설치된다.In addition, as shown in FIG. 2, the checker part 5 includes a casing 6 surrounding the outer surface of the checker part 5, a roller 8 provided at the center of the casing 6, and the roller 8. It is installed on both sides, the spring (7) is always pushed on both sides so that the roller (8) is caught when passing through the bend (2) to feel the theft.

상기 도어 체커는, 도어와 차체 사이드 부에 연결 설치되어 도어를 개방시켰을 때 그 열린 만큼의 상태를 유지시키는 작용과, 도어가 완전히 개방되었을 때 이 도어를 정지 및 개도 각 이상으로 개방되지 못하게 스토퍼의 역할을 하게 되는 것이다.The door checker is connected to the door and the body side part to maintain the open state when the door is opened, and stop the door when the door is fully opened so that the door cannot be opened beyond the opening and opening angles.

이하에서, 본 발명에 따른 자동차용 도어 체커 장치의 구성 및 그에 따른 실시예를 더욱 상세히 설명한다.Hereinafter, the configuration of the door checker device for a vehicle according to the present invention and its embodiment will be described in more detail.

자동차의 도어가 결합되는 차체 사이드 부에는 그 일단이 설치되고, 그 타단은 도어의 측면부에 연결 설치되어 자동차의 도어가 설정된 개도 각 이상으로 개방되는 것을 방지하기 위해 마련되는 자동차용 도어 체커 장치가 마련된다.One end is installed at the vehicle body side portion to which the door of the vehicle is coupled, and the other end thereof is connected to the side portion of the door, and an automobile door checker device is provided to prevent the door of the vehicle from being opened beyond a set opening angle. do.

상기 차체 사이드 부에 고정된 체커 브래킷에는 연결부(10)가 설치된다.The connector 10 is installed on the checker bracket fixed to the vehicle body side part.

상기 연결부(10)에는 그 일단이 설치되고, 그 타단은 도어에 결합되어 굴곡부(11)가 형성된 길다란 막대 형상의 체커암(12)이 마련된다.One end thereof is installed at the connection portion 10, and the other end thereof is coupled to the door, and a checker arm 12 having a long rod shape having a curved portion 11 is provided.

상기 체커암(12)의 타측단에는 도어의 내측부에 수용되어 도어가 개방될 때 그 충격을 흡수하는 스토퍼(20)가 관통되어 설치된다.The other end of the checker arm 12 is installed through the stopper 20 which is accommodated inside the door and absorbs the shock when the door is opened.

상기 체커암(12)에는 도어가 개폐될 경우 이 체커암(12)의 길이 방향을 따라 슬라이딩 이동되면서 상기 굴곡부(11)를 지날 때 도어의 개도 각을 느끼도록 하는 체커부(30)가 설치된다.When the door is opened or closed, the checker arm 12 is slidably moved along the longitudinal direction of the checker arm 12, and a checker part 30 is installed to feel the opening angle of the door when passing through the bent part 11. .

상기 체커부(30)는 체커암(12)에 에 결합되며, 이 체커부(30)는 체커암(12)에 관통되어 결합되는 관통구멍이 형성된 케이싱의 내부에 스프링에 의해 탄성적으로 지지되는 체커암(12)의 상, 하부면에 접하여 슬라이딩 이동하는 롤러가 구비되어 도어의 개폐시 절도감을 느끼게 해주는 것이다.The checker part 30 is coupled to the checker arm 12, and the checker part 30 is elastically supported by a spring in the casing in which a through hole is formed through and coupled to the checker arm 12. It is provided with a roller that slides in contact with the upper and lower surfaces of the checker arm 12 to feel theft when opening and closing the door.

상기 체커암(12)의 타단부에는 도어가 개도 각 이상으로 개폐될 때 그 충격이 1차적으로 완화될 수 있게 완충부(40)가 설치된다.The other end of the checker arm 12 is provided with a shock absorbing portion 40 so that the impact is primarily mitigated when the door is opened or closed over an opening angle.

또한, 상기 완충부(40)는 원형의 모양으로 형성된다.In addition, the buffer 40 is formed in a circular shape.

이는 도어를 열고 닫을 때 충격완화는 물론, 부드러운 작동감을 느끼게 하기 위해 원형의 형상으로 구성한 것이다.This is configured in a circular shape in order to feel a smooth operation feeling as well as shock mitigation when opening and closing the door.

이하에서, 본 발명에 따른 자동차용 도어 체커 장치의 그 기능을 알아본다.Hereinafter, the function of the door checker device for automobiles according to the present invention.

도 3에서 보듯이, 본 발명은 기존 기술에서 발생 가능한 문제를 체커암의 형상 변경을 통하여 해결하기 위해 제안된 것이다. As shown in Figure 3, the present invention has been proposed to solve the problem that can occur in the existing technology through the shape change of the checker arm.

변경되는 형상은 기존 체커암(12)의 끝단부 즉 스토퍼(20)가 위치하는 앞 부분에 원형 형상의 완충부(40)를 설치한 것이다.The shape to be changed is to install a circular shock absorbing portion 40 in the front end portion of the existing checker arm 12, that is, the stopper 20 is located.

따라서, 도어를 평상시의 힘으로 열게 되면 체커부는 1차적으로 완충부(40)에 걸려 완충부(40) 구간에 머무를 수 있도록 체커암(12)의 길이를 연장한다. Therefore, when the door is opened with a normal force, the checker unit primarily extends the length of the checker arm 12 to be caught in the buffer unit 40 and stay in the buffer unit 40 section.

이때, 그외 기능 및 형상은 기존의 체커와 동일하게 하여 최대한 변경 부분을 축소하고자 한다.At this time, other functions and shapes are to be the same as the existing checkers to reduce the change as possible.

또한, 상기 완충부(40)의 부위는 체커암(12)에 있는 각도 조절용 완충부(40) 부분의 지름 변경량의 0.5배 정도로 한다. 이는 완충부(40)의 지름이 커질 경우 체커 홀더의 신규 개발등의 여지가 있기 때문이다.Further, the portion of the buffer portion 40 is about 0.5 times the diameter change amount of the portion of the angle adjusting buffer portion 40 in the checker arm 12. This is because, if the diameter of the buffer portion 40 increases, there is room for new development of the checker holder.

이러한, 구성으로 자동차의 도어를 열게 되면 그 작동은 기존의 체커의 기능인 일정 열림각에서 도어를 고정하는 기능은 유지되나, 도 4에서 보듯이 도어를 큰 힘으로 열었을 때, 도어의 열림 힘을 스토퍼(20)가 직접 받는것이 아니라, 체커암(12)에 설치된 체커부(30)가 슬라이딩 되면서 체커부(30)는 1차 스토퍼 기능의 완충부(40)를 지나가게 된다.When opening the door of the car in such a configuration, the operation is maintained the function of fixing the door at a certain opening angle, which is a function of the conventional checker, but when the door is opened with a large force, as shown in Figure 4, the opening force of the door stopper Instead of being directly received by 20, the checker part 30 installed on the checker arm 12 slides, and the checker part 30 passes through the buffer part 40 of the primary stopper function.

이렇게, 상기 체커부(30)가 완충부(40)를 지나가게 되면서 그 힘은 1차적으로 감소하게 되어, 도어가 최대한 열리려는 힘과 스토퍼(20)의 반발력에 의해 발생되는 도어의 닫힘을 방지한다.As such, the checker portion 30 passes through the buffer portion 40 and the force is primarily reduced, thereby preventing the door from closing due to the force to open the door as much as possible and the repulsive force of the stopper 20. do.

상술한 바와 같이 본 발명에 따른 자동차용 도어 체커 장치에 의하면, 도어에 힘을 많이 가하여 열게 되더라도 완충부에 의해 그 힘이 감소되어 스토퍼에 의한 도어의 반발력을 줄여주게 되므로 도어가 다시 닫히는 것을 미연에 차단하여 승객의 부상을 미연에 방지할 수 있는 효과와, 상기와 같이 도어 체커의 스토퍼에 직접 가해지는 힘이 완충부를 통과하면서 감소 되므로 스토퍼의 크기를 축소 제작 가능함은 물론, 상기 스토퍼에 가해지는 힘이 줄어들게 됨으로써 도어에 직접적으로 마운틴 되는 부분의 변형이 최대한 줄어들게 되어 이에 따른 내구성 향상에도 큰 효과가 있다.As described above, according to the automotive door checker device according to the present invention, even if the door is opened by applying a lot of force, the force is reduced by the shock absorber to reduce the repulsive force of the door by the stopper. It is possible to reduce the size of the stopper, as well as the force applied to the stopper of the door checker is reduced while passing through the shock absorber as described above.
