본 발명은 버스의 스윙도어 개폐구조에 관한 것으로, 로터리실린더를 사용하지 않고, 가격이 저렴한 복동실린더를 사용하여 부드러운 개폐작동이 수행되어질 수 있도록 구성한 것이다.The present invention relates to a swing door opening and closing structure of a bus, and is configured so that a smooth opening and closing operation can be performed using a double-acting cylinder which is inexpensive without using a rotary cylinder.
종래 버스의 스윙도어는 제1도 및 제2도에 도시한 바와 같이, 승강구 발판(1)에 공압에 의하여 회전작동하는 로터리실린더(2)가 설치되어 있고, 이 로터리실린더(2)에는 상,하부가 베어링(3,4)에 의하여 고정지지된 드라이브 샤프트(5)가 축결합되어 있으며, 드라이브 샤프트(5)의 아암(6)은 도어(7)의 내측에 힌지고정되어 있어 로터리실린더(2)의 회전동작에 의하여 드라이브 샤프트(5)가 회전하면서 도어(7)가 개폐되도록 구성되어 있었다.As shown in FIGS. 1 and 2, a swing door of a conventional bus is provided with a rotary cylinder 2 which is rotatably operated by pneumatic pressure in the hatch footrest 1, and the rotary cylinder 2 has a top, The drive shaft 5 whose lower part is fixedly supported by the bearings 3 and 4 is axially coupled, and the arm 6 of the drive shaft 5 is hinged and fixed to the inside of the door 7 so that the rotary cylinder 2 The door 7 is opened and closed while the drive shaft 5 is rotated by the rotation operation of.
상기한 종래의 스윙도어(7)는 드라이브 샤프트(5)의 상,하 길이가 짧아 작동력이 도어(7)의 하부에 치우치게 되므로 개폐동작시 도어(7)가 흔들리게 되는 문제점이 있었고, 로터리실린더(2)는 통상의 복동실린더가 아닌 축이 회전하도록 구성된 특수한 구조이기 때문에 가격이 비싸 스윙도어의 제작원가가 상승하게 되는 폐단이 있었다.The conventional swing door 7 has a problem that the door 7 is shaken during the opening and closing operation because the upper and lower lengths of the drive shaft 5 are shortened and the operating force is biased to the lower part of the door 7. (2) is a special structure configured to rotate the shaft, not a normal double-acting cylinder, the price is expensive, there was a closing end that the production cost of the swing door will increase.
본 발명은 상기한 종래의 제반 문제점을 감안하여 안출된 것으로, 본 발명의 목적은 도어의 개폐작동시 도어의 흔들림이 없도록하여 부드러운 개폐가 가능하도록 하고, 스윙도어의 제작원가를 절감할 수 있도록 하는 데 있는 것이다.The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to enable the smooth opening and closing of the door during the opening and closing operation of the door, and to reduce the manufacturing cost of the swing door It is.
이와 같은 목적을 달성하기 위하여 본 발명은 차체에 베어링에 의하여 고정지지된 드라이브 샤프트의 상,하부에 형성된 소정길이의 아암을 도어에 힌지고정한 버스의 스윙도어 개폐구조에 있어서, 상기 드라이브 샤프트를 도어의 상,하부 길이에 비하여 길게 설치하고, 상기 드라이브 샤프트의 하부일 외측으로 브라켓을 부착하며, 상기 차체의 하부에 복동실린더의 선단을 힌지고정하며, 상기 브라켓에 복동실린더의 로드 선단을 핀결합한 것으로, 이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하기로 한다.In order to achieve the above object, the present invention provides a swing door opening and closing structure of a bus in which an arm having a predetermined length formed on an upper and a lower part of a drive shaft fixed to a vehicle body by a bearing is fixed to a door. It is installed longer than the upper and lower lengths, the bracket is attached to the outside of the lower end of the drive shaft, the front end of the double-acting cylinder is hinged fixed to the lower portion of the vehicle body, and the pin of the rod end of the double-acting cylinder to the bracket, Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제3도 및 제4도는 본 발명의 일 실시예에 따른 스윙도어의 개폐구조를 도시한 것으로, 본 실시예에서는 도어(10)의 상,하부 길이보다 긴 드라이브 샤프트(20)가 차체의 상,중,하부에 베어링(30,32,34)에 의하여 회전가능하도록 지지되고, 이 드라이브 샤프트(20)의 상,하부에 형성된 소정길이의 아암(22,24)은 도어의 상,하부 내면에 힌지고정된다.3 and 4 illustrate an opening and closing structure of a swing door according to an embodiment of the present invention. In this embodiment, the drive shaft 20 longer than the upper and lower lengths of the door 10 is formed on the upper and lower sides of the vehicle body. It is supported by the bearings 30, 32, 34 in the middle and the lower part so as to be rotatable, and arms 22 and 24 of predetermined length formed on the upper and lower parts of the drive shaft 20 are hinged on the upper and lower inner surfaces of the door. It is fixed.
또, 드라이브 샤프트(20)의 하부에 형성된 브라켓(26)에는 차체 하부에 힌지고정된 복동실린더(40)의 로드(42) 선단이 핀결합되어 복동실린더(40)의 왕복동작에 의하여 드라이브 샤프트(20)가 시계 및 반시계방향으로 회전하도록 구성된 것이다.In addition, the tip of the rod 42 of the double-acting cylinder 40 hinged to the lower portion of the vehicle body is pinned to the bracket 26 formed at the lower portion of the drive shaft 20 so that the drive shaft may be driven by the reciprocating motion of the double-acting cylinder 40. 20) is configured to rotate clockwise and counterclockwise.
이와 같이 구성된 본 발명은 복동실린더(40)에 압축공기를 공급하여 로드(42)를 전진동작시키면 차체의 하부에 힌지고정된 복동실린더(40)의 선단이 시계방향으로 회전하면서 복동실린더(40)의 로드(42)에 핀결합된 드라이브 샤프트(20)도 시계방향으로 회전함으로써 드라이브 샤프트(20)의 상,하부에 형성된 아암(22,24)에 힌지결합된 도어(10)가 열리게 되는 것이다.According to the present invention configured as described above, when the rod 42 is moved forward by supplying compressed air to the double-acting cylinder 40, the tip of the double-acting cylinder 40 hinged to the lower portion of the vehicle body rotates clockwise, and the double-acting cylinder 40 The drive shaft 20 pinned to the rod 42 of the rotation also rotates clockwise to open the door 10 hinged to the arms 22, 24 formed on the upper and lower portions of the drive shaft 20.
또, 도어(10)를 닫을 경우에는 복동실린더(40)에 역으로 압축공기를 공급하여 로드(42)를 후진동작시키면 차체의 하부에 힌지고정된 복동실린더(40)의 선단이 반시계방향으로 회전하면서 복동실린더(40)의 로드(42)에 핀결합된 드라이브 샤프트(20)도 반시계방향으로 회전함으로써 드라이브 샤프트(20)의 상,하부에 형성된 아암(22,24)에 힌지결합된 도어(10)가 닫히게 되는 것이다.In addition, when the door 10 is closed, the compressed air is supplied to the double-acting cylinder 40 in reverse, and the rod 42 is moved backward to move the tip of the double-acting cylinder 40 hinged to the lower portion of the vehicle body in the counterclockwise direction. The drive shaft 20 pinned to the rod 42 of the double-acting cylinder 40 while rotating also rotates counterclockwise so that the door is hinged to the arms 22 and 24 formed on the upper and lower portions of the drive shaft 20. (10) is to be closed.
이처럼 본 발명은 복동실린더(40)의 로드(42)의 전,후진동작에 의하여 드라이브 샤프트(20)가 회전하면서 도어(10)를 개폐시키게 되는 것으로, 드라이브 샤프트(20)는 상,하로 길게 형성되어 있고 아암(22,24)은 드라이브 샤프트(20)의 상,하부에 형성되어 있으므로 도어(10)의 개폐시 복동실린더(40)의 작동력이 도어(10)의 상,하부에 균등하게 걸리게 되어 도어(10)가 흔들리지 않게 되는 것이고, 복동실린더(40)는 종래의 로터리실린더에 비하여 구조가 간단하고 가격이 저렴하므로 스윙도어의 제작원가를 절감할 수 있는 것이다.As described above, the present invention is to open and close the door 10 while the drive shaft 20 rotates by the forward and backward movement of the rod 42 of the double-acting cylinder 40, and the drive shaft 20 is formed long up and down. Since the arms 22 and 24 are formed at the upper and lower portions of the drive shaft 20, the actuation force of the double acting cylinder 40 is equally applied to the upper and lower portions of the door 10 when the door 10 is opened and closed. The door 10 is not shaken, and the double-acting cylinder 40 can reduce the manufacturing cost of the swing door because the structure is simple and inexpensive as compared with the conventional rotary cylinder.
이상 설명한 바와 같이 본 발명은, 복동실린더에 의하여 도어의 상,하부에 걸쳐 길게 설치된 드라이브 샤프트가 회전하면서 도어를 개폐시킬 수 있도록 한 것으로, 본 발명에 의하면 드라이브 샤프트가 도어의 상,하부에 길게 설치되어 있고 아암이 도어의 상,하부에 힌지결합되어 회전력을 균등하게 전달하게 되므로 도어의 개폐동작이 부드럽게 되는 것이고, 복동실린더의 가격은 종래 로터리실린더의 가격에 비하여 매우 저렴하므로 스윙도어의 제작원가를 대폭절감할 수 있는 유용한 효과를 갖는다.As described above, the present invention allows the drive shaft to be opened and closed while the drive shaft installed over the upper and lower portions of the door is rotated by the double-acting cylinder. According to the present invention, the drive shaft is installed at the upper and lower portions of the door. Since the arm is hinged to the upper and lower parts of the door to transmit the rotation force evenly, the opening and closing operation of the door is smooth, and the price of double-acting cylinder is very cheap compared to the price of the conventional rotary cylinder. It has a useful effect that can be greatly reduced.
