자동차용 슬라이딩도어의 자동개폐장치{An automatic opening and closing device of sliding door for a motor vehicle}An automatic opening and closing device of sliding door for a motor vehicle}

도 1은 본 발명에 따른 개폐장치의 평면도.1 is a plan view of the opening and closing apparatus according to the present invention.

도 2는 도 1의 A-A선 일부확대단면도.2 is a partially enlarged cross-sectional view taken along the line A-A of FIG.

도 3과 도 4는 본 발명에 따른 개폐장치의 작동상태를 나타낸 평면도.3 and 4 are a plan view showing an operating state of the switchgear according to the present invention.

본 발명은 소형버스와 같은 자동차용 슬라이딩도어의 자동개폐장치에 관한 것이다.The present invention relates to an automatic opening and closing device of a sliding door for a vehicle such as a small bus.

종래에 대한민국 실용신안 공개번호 제 1995-8547 호에 제시된 자동개폐장치는 차체의 발판 위에 장착되는 베이스플레이트에 형성된 가이드레일에 끼워지고 슬라이딩도어와 연결되는 슬라이더의 양측에, 베이스플레이트 위에서 모터와 평기어만으로 연결되어서 회전하는 구동풀리와, 베이스플레이트 위에 고정된 반원형 가이드 사이에 걸려지는 와이어의 양쪽 끝부분을 고정시켜서 된 것이었다.The automatic opening and closing device disclosed in the Republic of Korea Utility Model Publication No. 1995-8547 is mounted on the guide rail formed on the base plate mounted on the foot plate of the vehicle body and on both sides of the slider connected to the sliding door, the motor and the spur gear on the base plate. It was made by fixing both ends of the wire which is connected between the driving pulley which is connected and rotated by the bay and the semicircular guide fixed to the base plate.

이와 같은 종래의 개폐장치는 모터의 출력만으로 슬라이더를 직선운동시켜주는 것이어서 동력소모량이 많았었고, 모터의 작동시간이 길어서 내구수명이 단축되 었으며, 슬라이딩도어를 신속하게 개폐시켜 줄 수 없었고, 슬라이딩도어가 정확하게 개, 폐 위치에 있도록 셋팅하기가 매우 어려웠었을 뿐만 아니라 사용도중에 와이어의 장력조절이 거의 불가능한 구조로 된 것이어서 오래 사용할 경우 슬라이딩도어를 정확하게 개, 폐시켜 줄 수 없게 되어서 작동신뢰도가 매우 낮아지게되는 등의 문제점이 있었다.Such a conventional switchgear is a linear movement of the slider only by the output of the motor, so the power consumption was large, the operating life of the motor was long, the durability was shortened, the sliding door could not be opened and closed quickly, the sliding door Is not only very difficult to set correctly in the opening and closing positions, but also because the structure is almost impossible to control the tension of the wire during use, so the sliding door cannot be opened and closed correctly when used for a long time. There was a problem such as being.

본 발명의 목적은 슬라이딩도어를 작은 동력으로도 신속정확하게 개폐시켜 줄 수 있고 작동중 충격과 소음이 발생하지 않으며 유지보수가 매우 용이하고 작동신뢰성과 내구성이 우수한 자동차용 슬라이딩도어의 자동개폐장치를 제공하는데 있다.An object of the present invention is to open and close the sliding door quickly and precisely even with a small power, it does not generate impact and noise during operation, very easy to maintain and provides an automatic opening and closing device of the sliding door for automobile excellent in operation reliability and durability. It is.

본 발명은 도 1과 도 2에 예시한 바와 같이 표현이 생략된 차체에 직선왕복운동 할 수 있도록 지지되는 슬라이딩도어(10)를 전기모터(12)로 개폐시켜주는 슬라이딩도어의 개폐장치로서, 같은 길이를 가진 여러개의 링크(14)가 핀(16)으로 결합된 평행운동기구(18)의 한쪽에 있는 링크(14a)가 하우징(20)에 고정핀(22)으로 고정되어 있으며, 상기 평행운동기구(18)의 다른쪽에 있는 링크(14b)에서 하우징(20) 밖으로 연장된 아암(24)에는 상기 슬라이딩도어(10)가 링크(26)와 핀(28)으로 연결되어 있고, 상기 평행운동기구(18)의 한 중간핀(16a)이 전기모터(12)의 회전축(30)과 연결된 구동스프로켓휠(32)과, 종동스프로켓휠(34)에 걸려진 체인(36)과 연결되어서 전기모터(12)가 시계방향 또는 시계반대방향으로 회전할 때 상기 중간핀 (16a)이 체인(36)을 따라서 직선왕복하게 되어서 도 3과 도 4에 예시한 바와 같이 평행운동기구(18)가 상기 중간핀(16a)의 운동거리보다 큰 폭으로 신축(伸縮)하면서 슬라이딩도어(10)를 밀거나 당겨서 신속, 정확하게 개폐시켜 줄 수 있도록 되어 있다.The present invention is an opening and closing device of the sliding door that opens and closes the sliding door 10 supported by the electric motor 12 so as to reciprocate linearly to the vehicle body, the expression is omitted, as illustrated in FIGS. The link 14a on one side of the parallel movement mechanism 18, in which several links 14 having lengths are coupled to the pins 16, is fixed to the housing 20 with fixing pins 22. The sliding door 10 is connected to the link 26 and the pin 28 by an arm 24 extending out of the housing 20 at the link 14b on the other side of the mechanism 18. An intermediate pin (16a) of (18) is connected to the drive sprocket wheel 32 connected to the rotating shaft 30 of the electric motor 12, and the chain 36 hooked to the driven sprocket wheel 34, the electric motor ( When 12) rotates clockwise or counterclockwise, the intermediate pin 16a is linearly reciprocated along the chain 36 As illustrated in FIGS. 3 and 4, the parallel movement mechanism 18 expands and contracts with a width larger than the movement distance of the intermediate pin 16a while pushing or pulling the sliding door 10 to open and close quickly and accurately. It is supposed to be.

본 발명에 있어서, 평행운동기구(18)가 정확하게 일직선상에서 신축운동 할 수 있도록 해주기 위해서는 평행운동기구(18)의 중간핀(16a)과 체인(36)을 도 2에 예시한 바와 같이 평행운동기구(18)의 윗쪽 또는 아래쪽에 위치하도록 하우징(20)의 내부에 볼트, 너트와 같은 통상적인 고정수단으로 장착되는 홈 형강(channel steel)과 같은 안내부재(38)의 길이방향으로 이동가능하게 지지되는 슬라이더(40)와, 이 슬라이더(40)의 중앙에 고정되는 연결축(42)으로 결합시켜주는 것이 바람직하다.In the present invention, in order to allow the parallel movement mechanism 18 to stretch in a straight line, the parallel movement mechanism is illustrated with the intermediate pin 16a and the chain 36 of the parallel movement mechanism 18 as illustrated in FIG. The housing 20 is movably supported in the longitudinal direction of the guide member 38, such as a channel steel, which is mounted in the housing 20 by conventional fixing means such as bolts and nuts so as to be located above or below 18. It is preferable to combine the slider 40 and the connecting shaft 42 fixed to the center of the slider 40.

도면 중 미설명부호 44는 안내부재(38)에서 연결축(42)이 이동가능하게 관통되는 슬로트이고, 46, 46´는 슬라이더(40)의 이동거리를 감지하여 전기모터(12)에 전원공급을 차단시켜주는 리미트스위치이다.In the drawing, reference numeral 44 denotes a slot through which the connecting shaft 42 movably penetrates from the guide member 38, and 46 and 46 'are supplied to the electric motor 12 by sensing the moving distance of the slider 40. It is a limit switch to cut off.

이와 같이 구성된 본 발명은 예시도면에 표현이 생략된 도어개폐스위치를 조작하는 것에 의해서 도 3과 도 4에 예시한 바와 같이 전기모터(12)의 회전축(30)이 시계방향 또는 시계반대방향으로 회전하게 되고, 상기 회전축(30)과 연결된 구동스프로켓휠(32)과 종동스프로켓휠(34)에 걸려진 체인(36)이 좌, 우측으로 직선운동하게 되며, 이 체인(36)과 연결된 슬라이더(40)가 좌, 우측으로 직선운동하게 된다.The present invention configured as described above rotates the rotation shaft 30 of the electric motor 12 clockwise or counterclockwise as illustrated in FIGS. The chain 36 caught by the driving sprocket wheel 32 and the driven sprocket wheel 34 connected to the rotary shaft 30 is linearly moved left and right, and the slider 40 connected to the chain 36 is rotated. ) Will linearly move left and right.

따라서 상기 슬라이더(40)와 중간핀(16a)이 연결축(42)으로 결합되어 있고 한쪽에 있는 링크(14a)가 하우징(20)에 고정되어 있는 평행운동기구(18)가 신축운동을 하게 되어서 평행운동기구(18)의 자유단부에 해당하는 링크(14b)의 아암(24)과 링크(26)로 연결된 슬라이딩도어(10)가 개, 폐위치로 이동하게 된다.Therefore, the slider 40 and the intermediate pin 16a are coupled to each other by the connecting shaft 42, and the parallel movement mechanism 18 in which the link 14a on one side is fixed to the housing 20 is stretched. The sliding door 10 connected to the arm 24 and the link 26 of the link 14b corresponding to the free end of the parallel motion mechanism 18 is moved to the open and closed positions.

이때 체인(36)과 슬라이더(40)의 직선왕복운동거리보다 평행운동기구(18)의 신축거리가 거의 2배 정도에 달하는 것이어서 즉, 전기모터(12)의 짧은 구동만으로도 슬라이딩도어(10)를 신속, 정확하게 개폐시켜 주게 된다.At this time, the expansion and contraction distance of the parallel movement mechanism 18 is almost twice that of the linear reciprocating movement distance of the chain 36 and the slider 40, that is, the sliding door 10 is opened only by a short drive of the electric motor 12. It opens and closes quickly and accurately.

그리고 슬라이딩도어(10)를 항상 일정한 힘과 속도록 개폐시켜 줄 수 있으므로해서 차체와 도어에 충격을 주지 않으므로 차체와 도어의 내구수명을 연장시켜주게 된다.In addition, since the sliding door 10 can be opened and closed at a constant force and speed at all times, it does not impact the body and the door, thereby extending the durability life of the body and the door.

또 전기모터(12)와 평행운동기구(18) 사이에서의 동력전달이 전동체인(36)에 의해서 이루어지는 것이기 때문에 제작에 높은 정밀도가 요구되지 아니하고 비교적 큰 허용공차를 가질 수 있는 것이어서 제작이 용이하고, 내마성이 우수하며, 작동소음이 유발되지 않는다.In addition, since power transmission between the electric motor 12 and the parallel motion mechanism 18 is made by the electric chain 36, high precision is not required for manufacturing and it is possible to have a relatively large tolerance so that manufacturing is easy. Excellent wear resistance and no noise.

본 발명에 따른 슬라이딩도어의 개폐장치는 슬라이딩도어를 작은 동력으로도 신속, 정확하게 개폐시켜 줄 수 있고, 작동 중 차체와 도어의 충격을 주지 않아서 차체와 도어의 내구수명을 연장시켜 줄 수 있으며, 비교적 큰 조립 허용 공차를 가지면서도 우수한 작동신뢰성을 발휘할 수 있고, 작동 소음이 거의 없으며 유지보수가 용이한 등의 장점이 있다.The opening and closing device of the sliding door according to the present invention can open and close the sliding door quickly and accurately even with a small power, and can extend the durability life of the body and the door by not impacting the body and the door during operation, and relatively While having a large assembly tolerance, it can exhibit excellent operating reliability, almost no operating noise, and easy maintenance.
