Description

초저상 버스용 스윙 도어{Swing door for bus}Swing door for bus

본 발명은 초저상 버스용 스윙 도어에 관한 것으로서, 보다 상세하게는 초저상 버스의 실내 플로워가 외부로 기울어져 있어서 스윙 도어 작동 시 저면의 브러쉬가 과변형되어 도어를 닫았을 때 밀폐가 되지 않는 것을 개선한 초저상 버스용 스윙 도어에 관한 것이다.The present invention relates to a swing door for an ultra low floor bus, and more particularly, that an indoor floor of an ultra low floor bus is inclined to the outside, so that the brush of the bottom surface is over-deformed when the swing door is operated so that the door is not closed when the door is closed. An improved ultra low-floor bus swing door.

일반적으로, 초저상 버스는 도심 주행용으로 많이 도입되고 있는 바, 특히 장애자용 휠체어등을 쉽게 싣고 내릴 수 있도록 플로워가 낮은 초저상 버스가 선호되는 것이다.In general, ultra-low-floor buses are often introduced for urban driving, and low-floor buses with low floors are particularly preferred for easily loading and unloading wheelchairs for the handicapped.

또한, 상기한 초저상 버스는 휠체어등의 출입이 원활하도록 개방각이 큰 스윙 도어를 장착하게 되고, 버스의 플로워에서 물이 외부로 빠지도록 외부가 낮아지는 경사를 주게 된다.In addition, the ultra-low-floor bus is equipped with a swing door having a large opening angle so as to facilitate entry and exit of wheelchairs, etc., and gives an inclination in which the outside is lowered so that water flows out from the floor of the bus.

즉, 상기한 초저상 버스는 도3에 도시된 바와 같이 외측으로 낮아지도록 경사 설치된 플로워(F)에 회전 가능하게 설치된 스윙 도어(50)와, 상기한 스윙 도어(50)의 저면에 설치되어 스윙 도어(50)와 플로워(F)와의 사이 간격을 차폐하는 브러쉬(51)로 스윙 도어(50)가 구성되어 상기한 브러쉬(51)가 도어를 닫았을 때 외부와 차량 실내를 차폐하게 되는 것이다.That is, the ultra low-floor bus is installed on the swing door 50 rotatably installed on the floor F inclined so as to be lowered to the outside as shown in FIG. 3, and is installed on the bottom of the swing door 50 to swing. The swing door 50 is configured by a brush 51 that shields the gap between the door 50 and the floor F, so that when the brush 51 closes the door, the outside and the vehicle interior are shielded.

물론, 상기한 브러쉬(51)는 초저상 버스의 실내 플로워(F)가 경사진 것을 커버할 수 있도록 충분히 길게 형성되어 있다.Of course, the brush 51 is formed long enough to cover the inclined floor F of the ultra-low bus.

그러나, 상기한 바와 같이 초저상 버스의 스윙 도어 저면에 브러쉬를 장착하여 스윙 도어를 닫았을 때 실내와 외부를 차폐하도록 구성하게 되면 상기한 브러쉬가 장시간 사용 시 과변형되어 스윙 도어를 닫았을 때, 외부와의 차폐가 이루어지지 않는 문제점이 있다. However, as described above, when the brush is mounted on the bottom of the swing door of the ultra low-floor bus and configured to shield the interior and exterior when the swing door is closed, when the brush is over-deformed when used for a long time, the swing door is closed. There is a problem that shielding from the outside is not made.

즉, 상기한 실내 플로워가 경사지게 설치되어 있기 때문에 상기한 브러쉬의 변형되는 것이 차량 실내측으로 갈수록 더욱 심하게 되고, 결과적으로 도어를 닫았을 때 차량 실내측으로 위치되는 부분의 브러쉬가 과변형됨으로써, 스윙 도어를 닫았을 때에도 이 부분에서 외부 공기가 유입되는 문제점이 있는 것이다.That is, since the above-described indoor floor is inclined, the deformation of the brush becomes more severe toward the vehicle interior side, and as a result, when the door is closed, the brush of the part positioned toward the vehicle interior side is over-deformed, so that the swing door is opened. Even when closed, there is a problem that outside air is introduced from this part.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 초저상 버스에 장착된 스윙도어를 개폐시킬 때 스윙 도어를 승강시킴으로써 브러쉬가 과변형되지 않도록 함과 아울러 이로 인해 스윙 도어를 닫았을 때 외부 공기가 유입되는 것을 방지할 수 있는 초저상 버스용 스윙 도어를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, when the swing door is lifted when opening and closing the swing door mounted on the ultra-low bus so that the brush is not over-deformed and when the swing door is closed by this, The present invention provides a swing door for an ultra-low bus that can prevent outside air from entering.

상기한 목적을 실현하기 위하여 본 발명은, 외측으로 갈수록 낮아지도록 차량 실내에 설치된 플로워와 밀착되면서 차량 실내를 외부와 차폐하도록 스윙 도어 저면에 설치된 브러쉬와, 상기한 스윙 도어를 회전시키도록 차량 본체에 설치된 회전축을 포함하는 초저상 버스용 스윙 도어에 있어서,In order to achieve the above object, the present invention is in close contact with the floor installed in the interior of the vehicle to be lowered toward the outside while the brush is installed on the bottom of the swing door to shield the interior of the vehicle and the outside, and the vehicle body to rotate the swing door In the ultra-low-floor bus swing door including an installed rotating shaft,

상기한 회전축을 차량 본체에서 일정 정도 승강할 수 있도록 설치하고 상기한 회전축 저면에 설치되어 이를 승강시킬 수 있게 설치된 피스톤과, 상기한 피스톤에 고압 공기를 충진/배출하여 스윙 도어가 닫혔을 때 하강시키고 열릴 때 상승시키도록 구성된 구동 수단을 포함함을 특징으로 한다.The piston is installed so as to lift and lower the vehicle body to a certain degree, and the piston is installed on the bottom of the rotary shaft so that it can be lifted and lowered when the swing door is closed by filling / discharging high pressure air to the piston. Drive means configured to raise when opened.

도1은 본 발명에 따른 초저상 버스용 스윙 도어를 도시한 개략 정면도로서, 초저상 버스의 본체(B)와 소정의 유격이 있도록 설치되어 승강 가능한 스윙 도어(50)의 회전축(H) 저면에 설치된 피스톤(1)과, 상기한 피스톤(1)에 고압 공기를 충진/배출하여 스윙 도어(50)가 닫혔을 때 하강시키고 열릴 때 상승시키도록 구성된 구동 수단으로 이루어져 있다.1 is a schematic front view showing a swing door for an ultra-low bus according to the present invention, which is installed on the bottom surface of a rotating shaft H of a swing door 50 which is installed to have a predetermined clearance with the main body B of the ultra-low bus. The piston 1 is provided, and the drive means configured to fill / discharge the piston 1 with high pressure air so as to descend when the swing door 50 is closed and ascend when it is opened.

상기한 구동 수단은 상기한 피스톤(1)에 배관(2)으로 연결 설치되어 양측의 피스톤(1)으로 공압을 인가하거나 배출하도록 설치된 솔레노이드 밸브(2)와, 상기한 솔레노이드 밸브(2)를 통해 고압 공기를 공급하는 에어 탱크(3)와, 상기한 솔레노이드 밸브(2)를 스윙 도어 스위치(SW)의 온/오프에 따라 동작시키도록 설치된 ECU(4)로 이루어져 있다.The driving means is connected to the piston (1) by the pipe (2) is installed through the solenoid valve (2) and the solenoid valve (2) installed to apply or discharge air pressure to the piston (1) on both sides An air tank (3) for supplying high pressure air and an ECU (4) provided to operate the solenoid valve (2) according to the on / off of the swing door switch (SW).

즉, 상기한 도어 스위치(SW)가 스윙 도어(50)의 개폐에 따라 온/오프되면 이에 따라 ECU(4)가 솔레노이드 밸브(2)를 온/오프시키게 됨으로써, 상기한 피스톤(1)에 고압 공기가 공급되거나 배출되도록 하여 스윙 도어(50)를 승강시키게 되는 것이다.That is, when the door switch SW is turned on / off as the swing door 50 is opened or closed, the ECU 4 turns the solenoid valve 2 on and off accordingly, thereby providing a high pressure to the piston 1. The air is supplied or discharged so as to elevate the swing door 50.

물론, 상기한 스윙 도어(50)가 열렸을 때에는 스윙 도어(50)를 상승시켜야 하기 때문에, 솔레노이드 밸브(2)를 통해 피스톤(1)에 고압 공기가 공급되고, 스윙 도어(50)가 닫혔을 때에는 솔레노이드 밸브(2)가 오프되면서 피스톤(1)의 고압 공기를 외부로 배출시켜 스윙 도어(50)가 하강하도록 하는 것이다.Of course, since the swing door 50 must be raised when the swing door 50 is opened, when the high pressure air is supplied to the piston 1 through the solenoid valve 2, the swing door 50 is closed. As the solenoid valve 2 is turned off, the swing door 50 descends by discharging the high pressure air of the piston 1 to the outside.

상기한 바와 같은 본 발명의 작용 효과를 도2a와 도2b에 따라 설명하면 스윙 도어(50)가 닫혔을 때에는 예를 들어, 도어 스위치(SW)가 온되어 있게 되고 상기한 도어 스위치(SW)의 온에 따라 ECU(4)가 솔레노이드 밸브(2)를 오프시키게 된다.2A and 2B, when the swing door 50 is closed, for example, the door switch SW is turned on and the door switch SW is turned on. Upon turning on, the ECU 4 turns off the solenoid valve 2.

솔레노이드 밸브(2)가 오프되면 상기한 피스톤(1)에 충진되어 있는 상태인 고압 공기가 솔레노이드 밸브(2)의 배출구로 배출되면서 상기한 스윙 도어(50)가 회전축(H)을 타고 하강하게 된다.When the solenoid valve 2 is off, the high pressure air, which is filled in the piston 1, is discharged to the outlet of the solenoid valve 2, and the swing door 50 descends on the rotation shaft H. .

스윙 도어(50)가 하강하게 되면 상기한 스윙 도어(50)의 저면에 설치된 브러쉬(51)가 차량 플로워(F)에 밀착된 상태가 된다.When the swing door 50 descends, the brush 51 installed on the bottom surface of the swing door 50 is in close contact with the vehicle floor F.

이 상태에서 상기한 스윙 도어(50)가 승객의 승하차등을 위해 열리게 되면 상기한 도어 스위치(SW)가 오프되고, 상기한 오프 신호가 ECU(4)에 전송됨과 아울러 솔레노이드 밸브(2)를 온시키게 된다.In this state, when the swing door 50 is opened for getting on and off the passenger, the door switch SW is turned off, the off signal is transmitted to the ECU 4, and the solenoid valve 2 is turned on. Let's go.

솔레노이드 밸브(2)가 온되면 상기한 배출구는 차단됨과 아울러 에어 탱크(3)에서의 고압 공기가 상기한 솔레노이드 밸브(2)를 통해 피스톤(1)으로 유입된다.When the solenoid valve 2 is turned on, the outlet is blocked and high pressure air from the air tank 3 flows into the piston 1 through the solenoid valve 2.

피스톤(1)으로 고압 공기가 유입되면 상기한 피스톤(1)이 회전축(H) 즉, 스윙 도어(50)를 상승시키게 되는 바, 이는 도2b에 도시된 바와 같이 플로워(F)가 내측으로 갈수록 높은 위치가 되지만 상기한 피스톤(1)의 상승에 의해 브러쉬(51)가 과다한 변형을 받지 않는 상태로 스윙 도어(50)가 열리게 되는 것이다.When the high pressure air flows into the piston 1, the piston 1 raises the rotation shaft H, that is, the swing door 50. As shown in FIG. 2B, as the floor F moves inward, The swing door 50 is opened in a state in which the brush 51 is not subjected to excessive deformation due to the rise of the piston 1 although the position becomes a high position.

즉, 상기한 초저상 버스의 플로워(F)가 외측이 낮고 내측이 높게 설계되어 있지만, 상기한 스윙 도어(50)가 열리면서 상승하기 때문에 브러쉬(51)가 과다한 변형을 받지 않게 되는 것이다.That is, although the floor F of the ultra-low bus is designed to have a low outer side and a high inner side, the brush 51 is not subjected to excessive deformation because the swing door 50 opens and rises.

브러쉬(51)가 스윙 도어(50)의 개폐 시 과다한 변형을 일으키지 않게 되면, 결과적으로 상기한 스윙 도어(50)가 닫혔을 때 플로워(F)와 정확하게 밀착됨으로써 외부 공기가 실내로 유입되는 것을 차단할 수 있게 되는 것이다.When the brush 51 does not cause excessive deformation when the swing door 50 is opened or closed, as a result, when the swing door 50 is closed, the brush 51 is closely adhered to the floor F, thereby preventing external air from entering the room. It will be possible.

물론, 상기한 에어 탱크(3)에는 도시되지 않은 컴프레서(버스의 브레이크 계통에 고압 공기를 공급하기 위해 설치되어 있는)에 의해 고압 공기가 항상 충진되는 상태가 된다.Of course, the air tank 3 is in a state where high pressure air is always filled by a compressor (not provided) for supplying high pressure air to the brake system of the bus.

이상과 같이 본 발명은 초저상 버스의 스윙 도어를 장착하여 사용할 때 외부와의 차폐를 위해 스윙 도어의 하부에 설치되어 있는 브러쉬의 과다한 변형을 방지하여 외부 공기가 차량 실내로 유입되는 것을 방지할 수 있는 잇점이 있는 것이다.As described above, the present invention can prevent excessive deformation of the brush installed in the lower part of the swing door for shielding the outside when the swing door of the ultra low-floor bus is mounted, thereby preventing outside air from entering the vehicle interior. There is an advantage.
