본 고안은 전동차의 슬라이딩 도어 스톱패킹이 관한 것이다.The present invention relates to a sliding door stop packing of an electric vehicle.
종래의 전동차 형상이 제3도에 도시한 바와 같이 직선형으로 전동차에 설치된 슬라이딩 도어 패킹이 제4도 및 제5도에 표시한 바와 같이 단면형상이 반원형으로 되어 있었다. 그러나 경제가 선진화 됨에 따라 전동차도 디자인면에서 미려하게 변형시키고자 외형을 제1도와 같이 곡선형으로 제조하고 있다.As shown in Fig. 3, the conventional sliding door packing provided in the electric vehicle in a linear shape has a semicircular cross section as shown in Figs. However, as the economy is advanced, in order to transform the electric cars beautifully in terms of design, they are manufactured in a curved shape as shown in FIG.
즉, 전동차외형의 미려함과 차내 공간의 증대를 목적으로 전동차 형상을 곡선형으로 제조함으로써 슬라이딩 도어 역시 곡선형으로 제작하지 않으면 않되는 것이다.That is, by manufacturing the shape of the train in a curved shape for the purpose of increasing the beauty of the exterior and interior space of the vehicle, the sliding door must also be manufactured in a curved shape.
따라서, 슬라이딩 도어 제작시 스톱 패킹을 제4도에서와 같이 반원형으로 형성하여 고장 설치하였을 경우 패킹의 재질이 크로로푸렌으로써 차량의 운향기간이 연장될수록 패킹의 내구성 및 정밀도 등이 감소하게 되어 틈이 벌어져 우천시 빗물의 칩입이 심해지는 등의 현상이 발생되고 있는 것이다.Therefore, if the stop packing is formed in a semi-circle shape as shown in FIG. 4 when the sliding door is manufactured, the packing material is made of chloropurene, and as the driving period of the vehicle is extended, the durability and precision of the packing decrease, and so on. There is a phenomenon such as severe rainwater intrusion in the rain.
따라서 본 고안은 상기의 결점을 보완하고자 고안한 것으로, 2개의 도어를 1조로 이루어진 슬라이딩 도어중 1개의 도어에 오목형의 원호면을 형성한 패킹을 고정 설치하여 반원형의 패킹과 상호 접촉됨으로써 틈의 벌어짐을 방지하고 그 패킹을 에틸렌-프로피렌(EPDM) 재질로 성형함으로써 내구성을 증대시켜 완전한 밀착력에 의해 우천시 빗물의 침입을 방지하는 것이다.Therefore, the present invention is designed to compensate for the above-mentioned drawbacks. The two doors are fixed by installing a concave circular arc-shaped packing on one of the sliding doors consisting of a set of two doors. By preventing the spreading and forming the packing of the ethylene-propylene (EPDM) material to increase the durability to prevent the ingress of rainwater in the rain by the full adhesion.
이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.
전동차(1)의 슬라이딩 도어(2a)(2b)에 반원형의 패킹(3)을 장착한 것에 있어서, 일측패킹(4)의 중간부에 돌기(5)를 돝출시킨 오목형의 원호면(6)을 형성시킨 것이고, 상기 패킹(4)을 에틸렌-프로피렌 재질로 형성시킨 것이다.In the case where the semicircular packing 3 is attached to the sliding doors 2a and 2b of the electric vehicle 1, the concave arcuate surface 6 in which the projection 5 was removed from the middle part of the one side packing 4. ) Is formed, and the packing 4 is formed of ethylene-propylene.
이와 같이 된 본 고안은 유압에 의해 양측 슬라이딩 도어(2a)(2b)가 자동으로 닫히게 될때 반원형의 패킹(3)과 오목형의 패킹(4)이 접촉하여 밀착하게 된다.The present invention as described above comes in close contact with the semi-circular packing 3 and the concave packing 4 when the two sliding doors 2a and 2b are automatically closed by hydraulic pressure.
이때, 반원형의 패킹(3)이 오목형의 패킹(4)에 밀착할 때, 반원형의 패킹(3)이 오목형의 패킹(4)의 돌기(5)에 먼저 접촉하면서 밀착하는데 계속적인 유압에 의해 반원형의 패킹(3)이 찌그러지면서 쐐기(7)에 접촉하게 된다.At this time, when the semi-circular packing 3 is in close contact with the concave packing 4, the semi-circular packing 3 is first in contact with the projection 5 of the concave packing 4 and is in close contact with the hydraulic pressure. As a result, the semicircular packing 3 is crushed to come into contact with the wedge 7.
왜냐하면 오목형의 패킹(4)은 재질이 에틸렌-프로피페으로 경도가 반원형의 패킹(3) 보다 강하기 때문에 반원형의 패킹(3)이 먼저 찌그러지게 되는 것이다.Because the concave packing 4 is made of ethylene-propipe, the hardness of the semi-circular packing 3 is stronger than that of the semi-circular packing 3.
따라서, 반원형의 패킹(3)이 찌그러져 쐐기(7)에 접촉할때 그 쐐기(7)에 의해 오목형의 패킹(4)도 찌그러지게 된다. 즉, 돌기(5)부분이 먼저 수축되면서 오목형의 원호면(4)인 양단이 반원형의 패킹(3)에 접촉하게 된다.Thus, when the semicircular packing 3 is crushed to contact the wedge 7, the concave packing 4 is also crushed by the wedge 7. That is, the protrusion 5 is first contracted so that both ends of the concave circular arc surface 4 come into contact with the semicircular packing 3.
그러므로 반원형의 패킹(3)에 돌기(5) 및 오목형의 패킹(4)의 양단(8a)(8b)이 접촉되어 밀착됨으로써 2중 3중으로 밀착시키는 결과로 정밀도를 유지시킬 수 있어 우천시 빗물의 침입을 방지할 수가 있는 것이다. 그리고, 쐐기(7)는 패킹(3)의 상하부 2군데 고정하여 일체로 형성시킨 것이다.Therefore, the semi-circular packing 3 is brought into contact with both the projections 8 and the both ends 8a and 8b of the concave packing 4 so that the precision can be maintained as a result of two-fold close contact. Intrusion can be prevented. The wedges 7 are fixed to two upper and lower portions of the packing 3 and formed integrally.
