The present invention relates to an entrance door of a city train applied with metallic prismatic cores, which employs a prismatic core structure of a lattice truss core or a channel shape, whose core material, which forms the entrance door of a city train and is placed in between an outer shell and an inner shell, is made from regular porous metal. According to the present invention, core materials made from metallic prismatic cores are applied to the entrance door of a city train to make the weight lighter and extend the functions compared with the conventional entrance door which employs core materials of a honeycomb structure. In particular, the present invention can be usefully applied to design and manufacturing of a streamlined shape which can reduce the weight and air resistance of a train to achieve the recent development trends of trains, which are better fuel efficiency and greater transportation efficiency, since it can make the weight of the entrance door of a city train lighter.

    본 발명은 프리즈매틱 코어 금속을 적용한 도시철도차량 전동차 출입문에 관한 것으로, 도시철도차량 전동차 출입문을 구성하며 외피와 내피 사이에 구비되는 심재는 규칙적 다공질 금속으로 이루어지는 격자형 트러스 코어(lattice truss core) 구조 또는 채널형태의 프리즈매틱 코어 구조를 채용한다. 본 발명에 따르면, 철도차량 전동차의 출입문에 프리즈매틱 코어 금속으로 이루어지는 심재를 적용하여 기존 하니콤 구조의 심재를 채용한 출입문에 비해 경량화와 기능을 확장할 수 있는 장점이 있다. 특히 본 발명은 철도차량 전동차의 출입문을 경량화할 수 있어 최근 철도차량의 개발 추세가 저연비, 고효율화를 달성하기 위하여 차량의 경량화와 공기저항을 감소시킬 수 있는 유선형의 차체형상을 설계 및 제작에 유용하게 적용할 수 있다.
