The invention relates to the technical field of railway vehicles, in particular to a double-flow-system vehicle built-in air-tight door which comprises two upper guide rails and two door leaves. Upper guide wheels are fixedly arranged at the tops of the door leaves; the two upper guide rails are respectively matched with the upper guide wheels of the corresponding door leaves; lower guide rails are fixedly arranged on the lower portions of the door leaves; the door further comprises two lower swing arms, each lower swing arm comprises a lower supporting rolling wheel assembly, and rolling wheels in the two lower supporting rolling wheel assemblies are matched with the lower guide rails of the corresponding door leaves respectively; the upper guide rail and the lower guide rail respectively comprise a linear section and a bent section; the opposite sections of the two upper guide rails are bent sections, and the other parts are linear sections; the opposite sections of the two lower guide rails are bent sections, and the rest parts are linear sections; and the directions of the upper guide rail bending section and the lower guide rail bending section vertical to the door leaf are opposite. Compared with an existing built-in door, when the door leaf reaches the closed state, the sealing performance can be greatly improved.

    本发明涉及轨道车辆技术领域,具体涉及一种双流制车辆内藏密闭门,包括两条上导轨和两个门扇;门扇顶部均固设有上导向轮,两条上导轨分别与对应门扇的上导向轮配合;门扇下部固设有下导轨;还包括下摆臂,下摆臂有两个,下摆臂包括下支撑滚轮组件,两个下支撑滚轮组件中的滚轮分别与对应门扇的下导轨配合;上导轨和下导轨分别包括直线段和弯转段;两个上导轨相对的一段为弯转段,其余部分为直线段;两个下导轨相背的一段为弯转段,其余部分为直线段;上导轨弯转段与下导轨弯转段垂直于门扇的朝向相反。与现有内藏门相比,本申请当门扇达到关闭状态时,可以极大的提升密封性。
