본 발명에 의한 철도차량용 슬라이딩 도어의 방음장치는 도 3에 도시한 바와 같이 레일(130)을 따라 슬라이드 이동하는 양문개폐형 슬라이딩 도어(110)의 후단 양측에 도어몰딩(111)이 결합되고, 철도차량의 도어가 열렸을 때 상기 슬라이딩 도어(110)가 내삽되어 안착되는 포켓부(120)의 출구 양측에 포켓몰딩(121)이 결합됨으로써 본 발명의 슬라이딩 도어 방음장치가 구성된다.In the soundproofing device for a sliding door for a railway vehicle according to the present invention, as shown in FIG. 3, the door molding 111 is coupled to both rear ends of the rear door opening and closing sliding door 110 that slides along the rail 130, and the railway vehicle. The sliding door soundproofing device of the present invention is configured by coupling the pocket molding 121 to both sides of the outlet of the pocket part 120 in which the sliding door 110 is inserted and seated when the door is opened.

철도차량의 도어를 열면 상기 슬라이딩 도어(110)가 포켓부(120)의 내부로 슬라이딩 이동하여 포켓부(120)의 내부에 안착되고, 철도차량의 도어를 닫으면 상기 양측의 슬라이딩 도어(110)가 포켓부(120)에서 나오면서 슬라이딩 도어(110)의 후단 양측에 결합된 도어몰딩(111)이 포켓부(120)의 출구 양측에 결합된 포켓몰딩(121)과 상접함으로써 슬라이딩 도어(110)와 포켓부(120) 사이의 틈이 밀폐되어 철도차량의 주행소음이 실내로 유입되는 것을 차단한다.When the door of the railroad vehicle is opened, the sliding door 110 is slid to the inside of the pocket part 120 to be seated inside the pocket part 120. When the door of the railroad car is closed, the sliding doors 110 on both sides are closed. The door molding 111 coupled to both rear ends of the sliding door 110 while coming out of the pocket part 120 is in contact with the pocket molding 121 coupled to both sides of the outlet of the pocket part 120, thereby sliding the door 110 and the pocket. The gap between the parts 120 is closed to block the running noise of the railway vehicle from entering the room.

그리고, 상기 슬라이딩 도어(110)가 닫혔을 때 상기 도어몰딩(111)이 포켓몰 딩(121)과 접하는 부분과, 상기 포켓몰딩(121)이 도어몰딩(111)과 접하는 부분에 경사부가 형성됨으로써 도 3에 도시한 바와 같이 슬라이딩 도어(110)와 포켓부(120) 사이의 틈이 밀폐됨은 물론, 철도차량이 주행할 때 발생하는 진동에 의하여 상기 슬라이딩 도어(110)가 흔들리는 것을 방지하는 것이 바람직하다.When the sliding door 110 is closed, the door molding 111 is in contact with the pocket molding 121, and the pocket molding 121 is inclined at the portion contacting the door molding 111. As shown in FIG. 3, the gap between the sliding door 110 and the pocket part 120 may be sealed, and the sliding door 110 may be prevented from shaking due to vibration generated when the railroad vehicle runs. Do.

상기 도어몰딩(111)은 슬라이딩 도어(110)의 높이에 해당하는 길이로 상기 슬라이딩 도어(110)의 후단 양측에 결합되는 것이 바람직하고, 상기 포켓몰딩(121)은 포켓부(120)의 높이에 해당하는 길이로 상기 포켓부(120)의 출구 양측에 결합되는 것이 바람직하다.The door molding 111 is preferably coupled to both sides of the rear end of the sliding door 110 in a length corresponding to the height of the sliding door 110, the pocket molding 121 is at the height of the pocket portion 120 It is preferable to be coupled to both sides of the outlet of the pocket portion 120 in a corresponding length.

그리고, 상기 도어몰딩(111)과 슬라이드몰딩(121)은 탄성이 있는 고무소재 또는 우레탄소재를 사용하여 성형되는 것이 바람직한데, 이는 슬라이딩 도어(110)를 닫았을 때 도어몰딩(111)과 포켓몰딩(121)이 상접할 때 상기 도어몰딩(111)과 포켓몰딩(121)이 약간의 탄성 변형을 하며 접함으로써 더욱 강하게 상호 밀착되어 상기 슬라이딩 도어(110)와 포켓부(120)의 틈을 밀폐시킴은 물론 철도차량의 주행 중 발생하는 진동에 의해 상기 슬라이딩 도어(110)가 흔들려 소음이 발생하는 것을 방지한다.In addition, the door molding 111 and the slide molding 121 is preferably molded using an elastic rubber material or urethane material, which is the door molding 111 and the pocket molding when the sliding door 110 is closed. When the door 121 is in contact with each other, the door molding 111 and the pocket molding 121 make contact with each other more strongly by making a slight elastic deformation and sealing the gap between the sliding door 110 and the pocket part 120. Of course, the sliding door 110 is prevented from shaking due to the vibration generated during the running of the railway vehicle.

본 발명의 다른 실시예에 의한 철도차량용 슬라이딩 도어의 방음장치는 도 4에 도시한 바와 같이 상기 포켓몰딩(121)과 도어몰딩(111)의 내부에 중공부(140)가 형성됨으로써, 슬라이딩 도어(110)가 닫혔을 때 상기 중공부(140)가 형성된 포켓몰딩(121)과 도어몰딩(111)이 더욱 밀착되도록 상접하여 포켓부(120)와 슬라이딩 도어(110)의 틈을 밀폐시키도록 구성된다.In the soundproofing device for a sliding door for a railway vehicle according to another embodiment of the present invention, as shown in FIG. 4, the hollow part 140 is formed inside the pocket molding 121 and the door molding 111, thereby providing a sliding door ( When the 110 is closed, the pocket molding 121 and the door molding 111 in which the hollow part 140 is formed are brought into close contact with each other to close the gap between the pocket part 120 and the sliding door 110. .

또한, 도 3에 도시한 바와 같이 상기 양문 개폐형 슬라이딩 도어(110)의 선단에는 패킹(112)을 체결하는 것이 바람직한데, 이는 상기 양측 슬라이딩 도어(110)가 닫혔을 때 슬라이딩 도어(110)가 접하는 부분의 틈으로 철도차량의 주행소음이 유입되는 것을 상기 패킹(112)이 차단한다.In addition, it is preferable to fasten the packing 112 to the front end of the two-door opening and closing sliding door 110, as shown in Figure 3, which is in contact with the sliding door 110 when the two sliding doors 110 are closed. The packing 112 blocks the running noise of the railway vehicle into the gap between the portions.

그리고, 도 6에 도시한 바와 같이 슬라이딩 도어(110)의 하부에 브러쉬(131)를 설치함으로써 상기 슬라이딩 도어(110)와 바닥의 틈으로 유입되는 철도차량의 주행소음을 차단하는 것이 바람직하다.And, as shown in Figure 6 it is preferable to block the running noise of the railway vehicle flowing into the gap between the sliding door 110 and the floor by installing the brush 131 in the lower portion of the sliding door 110.

상기 슬라이딩 도어(110)는 여닫힐 때 슬라이딩 도어(110)의 롤러(미도시)가 바닥에 부설된 레일(130)을 따라 여닫히게 되는 데 상기 레일(130)을 따라 슬라이드 이동하는 슬라이딩 도어(110)와 바닥의 틈으로 철도차량의 주행소음이 유입되는 것을 차단하기 위하여 상기 슬라이딩 도어(110)의 하부에 브러쉬(131)가 바닥에 닿도록 설치하는 것이 바람직하다.When the sliding door 110 is opened and closed, a roller (not shown) of the sliding door 110 is opened and closed along the rail 130 installed on the floor, and the sliding door 110 slides along the rail 130.
