The invention discloses a sliding door mechanism, a vehicle compartment structure and a railway vehicle. The sliding door mechanism comprises a fixed cover plate; the sliding door body is arranged on the fixed cover plate in a sliding or rolling manner; one end of the elastic telescopic piece is rotationally connected with the fixed cover plate, and the other end is rotationally connected with the sliding door body; wherein the sliding door body has three states, namely an open state, a balanced state and a closed state, and in the open state, the angle between the telescopic direction of the elastic telescopic piece and the moving direction of the sliding door body when the sliding door body is opened is larger than 0 degree and smaller than 90 degrees; in the balanced state, the angle between the telescopic direction of the elastic telescopic piece and the moving direction when the sliding door body is opened is equal to 90 degrees, and the elastic telescopic piece is compressed; in the closed state, the angle between the telescopic direction of the elastic telescopic piece and the moving direction of the sliding door body when the sliding door body is closed is larger than 0 degree and smaller than 90 degrees. According to the sliding door mechanism, bidirectional assistance of opening and closing is achieved, and the phenomenon that a sliding door is not opened in place or is not closed in place is reduced.

    本发明公开了一种拉门机构、车辆包间结构和轨道车辆。该拉门机构包括:固定罩板;拉门本体,滑动或者滚动设置于固定罩板;弹性伸缩件,其一端与固定罩板转动连接,另一端与拉门本体转动连接;其中,拉门本体具有三种状态,分别为打开状态、平衡状态和关闭状态,在打开状态,弹性伸缩件的伸缩方向与拉门本体打开时的移动方向之间的角度大于0°且小于90°;在平衡状态,弹性伸缩件的伸缩方向与拉门本体打开时的移动方向之间的角度等于90°,弹性伸缩件被压缩;在关闭状态,弹性伸缩件的伸缩方向与拉门本体关闭时的移动方向之间的角度大于0°且小于90°。该拉门机构实现了开启和关闭的双向助力,减少了拉门打开不到位或者拉门关闭不到位的现象。
