본 발명은 자동차의 도어체커에 관한 것으로서, 보다 상세하게는 자기 유동체 재료를 이용하여 도어의 움직임을 제어하여 도어가 강하게 닫히는 현상을 방지하도록 된 슬램방지기능을 갖는 자동차의 도어체커에 관한 것이다.The present invention relates to a door checker of an automobile, and more particularly, to a door checker of a vehicle having a slam-proof function to prevent the door from being strongly closed by controlling the movement of the door using a magnetic fluid material.

일반적으로, 자동차에는 탑승자가 출입할 수 있도록 적어도 2개소 이상에 출입구가 마련되고 그 출입구에는 도어가 형성되는바, 이 도어를 개폐 및 지지하는 수단으로, 도어힌지와 도어체커가 널리 사용된다.In general, the door is provided in at least two places for the occupant to enter the car and the door is formed in the door, the door hinge and the door checker is widely used as a means for opening and closing the door.

대개, 상기 도어힌지는 도어와 자동차 바디 사이의 상, 하부 2곳에 설치되어 도어의 자중을 견딤과 동시에 힌지핀을 매개로 도어의 개폐 기능을 담당하고, 상기 도어체커는 상기 상, 하부에 설치된 도어힌지의 중간에 위치하며 도어가 소정의 각도만큼 열려 있도록 하는 홀드기능과 완전히 열렸을 때 멈추게 하는 스톱기능을 가진다.Usually, the door hinge is installed on the upper and lower portions between the door and the car body to withstand the weight of the door and at the same time, the door hinge is opened and closed by the hinge pin, and the door checker is installed on the upper and lower doors. It is located in the middle of the hinge and has a hold function that allows the door to be opened by a predetermined angle and a stop function that stops when fully opened.

게다가, 상기 도어체커는 도어가 개폐될 때 발생할 수 있는 안전사고에 대비하여 도어가 열리고 닫힐 때, 보통 2∼3 단계의 개폐과정을 거치도록 함으로써 갑자기 닫히는 도어에 의한 안전사고의 위험을 미연에 방지하는 중요한 기능을 갖는다.In addition, the door checker prevents the risk of safety accidents due to the sudden closing of the door by opening and closing the door in two or three stages in preparation for a safety accident that may occur when the door is opened or closed. Has an important function.

종래의 도어체커는 도1에 도시된 것처럼, 다수개의 굴곡부(1)를 갖는 길다란 막대 형상의 체커아암(2)을 갖는바, 상기 체커아암(2)의 일측 단부는 핀(3)을 매개 로 자동차의 바디에 설치되고 타측 단부는 스토퍼(4)가 마련되어 도어의 내측에 설치된다. 따라서, 도어를 개폐할 때, 도어에 설치된 체커몸체(5)의 롤러(6)가 체커아암(2)의 굴곡부(1)를 따라 이동하는 작용에 의해 도어가 순차적으로 개폐되며, 도어가 최대로 열리면 스토퍼(4)가 체커몸체(5)에 걸려 도어의 열림이 제한된다.The conventional door checker has an elongated rod-shaped checker arm 2 having a plurality of bends 1, as shown in FIG. 1, and one end of the checker arm 2 is connected via a pin 3. Installed on the body of the vehicle and the other end is provided with a stopper (4) is installed inside the door. Therefore, when opening and closing the door, the door is opened and closed sequentially by the action of the roller 6 of the checker body 5 installed on the door moving along the bent portion 1 of the checker arm 2, and the door is opened to the maximum. When opened, the stopper 4 is caught by the checker body 5 to limit the opening of the door.

그러나, 상기한 종래의 도어체커는 도어의 순차적 개폐와 최대 열림 각도를 제어하는 단순한 기능을 가질 뿐, 도어의 급격한 개폐를 방지하는데 적합하지 않으며, 이는 도어가 급격하게 닫힐 때 승객에게 불쾌감과 위협감을 주며, 도어 및 필러 부위가 변형되거나 그 변형에 의한 소음 및 진동의 발생과 내구 수명의 저하는 물론, 도어의 급격한 개폐에 의한 안전사고의 위험을 가지고 있었다.However, the above-mentioned conventional door checker has only a simple function of controlling the sequential opening and closing of the door, and is not suitable for preventing the sudden opening and closing of the door, which is unpleasant and threatening to the passengers when the door is suddenly closed. In addition, the doors and pillars were deformed or deformed, and noise and vibration caused by the deformed and deteriorated endurance life, as well as the risk of safety accidents due to the sudden opening and closing of the door.

따라서, 본 발명은 상기한 종래의 문제점을 해결하기 위한 것으로서, 자기 유동체 재료를 이용하여 도어의 움직임을 제어하여 도어가 강하게 닫히는 슬램현상을 방지할 수 있도록 된 슬램방지기능을 갖는 자동차의 도어체커를 제공함에 그 목적이 있다.Accordingly, the present invention is to solve the above-mentioned problems, the door checker of a vehicle having a slam prevention function that can prevent the slam phenomenon that the door is strongly closed by controlling the movement of the door using a magnetic fluid material.

그리고, 상기에서 1차 코일(36)은 제1 챔버(32)의 중앙 부위에 대한 일정 길이에 감겨져 도어의 개방 초기 및 개방 말기에서 도어의 회전이 부드럽게 하는 것이 좋다.In addition, the primary coil 36 is wound around a predetermined length with respect to the central portion of the first chamber 32, it is preferable to smooth the rotation of the door at the beginning and end of opening the door.

상기한 구성으로 된 본 발명의 작용을 설명한다.The operation of the present invention having the above configuration will be described.

도어를 개폐시키는 경우, 체커아암(13)의 스토퍼(14)가 제1 하우징(20)의 일측에서 타측으로 이동되며, 동시에 그 스토퍼(14)에 고정 설치된 마그네틱 바(16)와 연장바(17)도 제2 하우징(30)의 일측에서 타측으로 이동된다.When opening and closing the door, the stopper 14 of the checker arm 13 is moved from one side of the first housing 20 to the other side, and at the same time, the magnetic bar 16 and the extension bar 17 fixed to the stopper 14 are fixed. ) Is also moved from one side of the second housing 30 to the other side.

이때, 상기 마그네틱 바(16)의 이동에 의해 1차 코일(36)에서 전자기가 유도되며, 1차 코일(36)에 전류 및 전압이 발생되고, 이 전류 및 전압은 구리도선의 수 및 마그네틱 바(16)의 속도에 비례한다(패러데이의 법칙에 의함).At this time, the electromagnetic is induced in the primary coil 36 by the movement of the magnetic bar 16, the current and voltage is generated in the primary coil 36, the current and voltage is the number of magnetic wires and the magnetic bar Proportional to (16) (by Faraday's law).

또한, 상기 1차 코일(36)은 2차 코일(38)에 연결되어 있는바, 상기 1차 코일(36)에 발생된 전류가 2차 코일(38)에 흐르면서 전자기장을 형성시킨다.In addition, the primary coil 36 is connected to the secondary coil 38, the current generated in the primary coil 36 flows to the secondary coil 38 to form an electromagnetic field.

그리고, 상기 2차 코일(38)에 의해 형성된 전자기장은 제2 챔버(34)에 충전된 자기유동체 재료(40)의 밀도를 크게 하며, 이렇게 자기유동체 재료(40)의 밀도가 증가되면 댐퍼(18)의 이동 속도가 감소된다.In addition, the electromagnetic field formed by the secondary coil 38 increases the density of the magnetorheological material 40 filled in the second chamber 34. When the density of the magnetorhesive material 40 is increased, the damper 18 is increased. ) Moving speed is reduced.

즉, 상기 마그네틱 바(16)의 이동 속도는 도어의 회전 속도에 비례하는바, 도어가 빠르게 개방되거나 닫히는 경우, 1차 코일(36)에 더 큰 전류 및 전압이 발 생됨과 동시에 2차 코일(38)에 의한 전자기장의 세기가 증가되며, 이는 자기유동체 재료(40)의 밀도가 더욱 크게 하여 댐퍼(18)의 이동 속도를 급격하게 감소시킴으로써 도어의 회전 속도를 낮출 수 있는 것이다.That is, the moving speed of the magnetic bar 16 is proportional to the rotational speed of the door. When the door is opened or closed quickly, a larger current and voltage are generated in the primary coil 36 and the secondary coil ( 38, the strength of the electromagnetic field is increased, which is to increase the density of the magnetic fluid material 40 to be able to lower the rotational speed of the door by drastically reducing the moving speed of the damper 18.

상술한 바와 같이 본 발명에 따른 슬램방지기능을 갖는 자동차의 도어체커에 의하면, 도어의 회전 속도에 비례하여 밀도가 증가되는 자기유동체 재료를 이용하여 도어의 회전 속도를 제어할 수 있는 우수한 효과를 갖는다.As described above, according to the door checker of a vehicle having a slam prevention function according to the present invention, it has an excellent effect of controlling the rotation speed of the door by using a magnetic fluid material whose density is increased in proportion to the rotation speed of the door. .

특히, 도어가 빠른 속도로 개폐되는 경우, 자기유동체 재료의 밀도가 더욱 커져 도어의 회전을 억제함으로써 도어의 급격한 개폐에 의한 승객의 불쾌감 및 위협감이 해소되며, 도어 및 필러 부위의 변형은 물론 그 변형에 의한 소음 및 진동의 발생을 억제하며, 안전사고의 위험을 방지하는 우수한 효과를 갖는다.In particular, when the door is opened and closed at a high speed, the density of the magnetic fluid is further increased to suppress the rotation of the door, thereby eliminating the discomfort and threat of passengers due to the sudden opening and closing of the door. It suppresses the occurrence of noise and vibration by, and has an excellent effect of preventing the risk of safety accidents.
