The invention provides an opening and closing mechanism and a railway vehicle. The opening and closing mechanism comprises a first side opening and closing assembly. The first side opening and closingassembly comprises a supporting base body, a rotating arm and a driving arm; the rotating arm is rotationally connected with the supporting base body; the driving arm is rotationally connected with the supporting base body; the rotation axis, relative to the supporting base body, of the rotating arm and the rotation axis, relative to the supporting base body, of the driving arm are arranged at intervals; and the driving arm is connected with the rotating arm through a motion transmission mechanism, so that the driving arm can rotate to drive the rotating arm to rotate. The opening and closingmechanism can be used for a railway vehicle to control opening and closing of a vehicle fairing. According to the opening and closing mechanism, a motion driving structure of a rotating shaft openingand closing mechanism is improved, the rotation axis, relative to the supporting base body, of the rotating arm and the rotation axis, relative to the supporting base body, of a rotating arm drivingstructure are designed to be of a non-coaxial structure, rotating arm driving action components are separated from the rotating arm, the action space of the rotating arm driving structure is increased, and the problem of motion interference among components in the opening and closing process of the fairing can be effectively solved.

    本发明提供一种开闭机构及轨道车辆。开闭机构包括第一侧开闭组件,所述第一侧开闭组件包括:支撑基体;转臂:所述转臂与所述支撑基体转动连接;驱动臂:与支撑基体转动连接;转臂相对支撑基体的转动轴线,与驱动臂相对支撑基体的转动轴线呈间隔设置;驱动臂与所述转臂经运动传动机构连接,以使驱动臂的转动可驱动转臂转动。该开闭机构可用于轨道车辆,控制车辆导流罩的开闭。开闭机构改进了转轴开闭机构的运动驱动结构,通过将转臂相对支撑基体的转动轴线,和转臂驱动结构相对支撑基体的转动轴线,设计为非同轴结构,实现了将转臂驱动动作部件从转臂中分离,增加了转臂驱动结构的作用空间,可有效解决导流罩开闭过程中部件之间的运动干涉问题。
