The invention provides a flow guide structure of a pantograph, a car roof structure and a railway vehicle. The flow guide structure comprises a fairing; the fairing is arranged on the roof corresponding to the pantograph and is used for guiding airflow flowing through the pantograph; wherein the pantograph comprises a pantograph rising state and a pantograph falling state; and the fairing at least covers the pantograph in the pantograph descending state. According to the flow guide structure of the pantograph, the car roof structure and the railway vehicle, the pantograph is closed in a pantograph descending state by arranging the flow guide cover capable of covering the pantograph, so that the pantograph is isolated from external air flow, aerodynamic resistance of a pantograph area is reduced, and meanwhile, after the pantograph is isolated from the external air flow, aerodynamic noise generated by pantograph descending is eliminated, and therefore noise generated in the running process of the railway vehicle is reduced.

    本发明提供一种受电弓的导流结构、车顶结构及轨道车辆,所述导流结构包括:导流罩;所述导流罩在车顶对应受电弓设置,用于引导流经所述受电弓的气流;其中,所述受电弓包括升弓状态和降弓状态;所述导流罩至少罩设处于所述降弓状态下的所述受电弓。本发明提供的一种受电弓的导流结构、车顶结构及轨道车辆,通过设置能够罩设受电弓的导流罩,实现了在降弓状态对受电弓进行封闭,从而隔离受电弓与外部气流,减小受电弓区域的气动阻力,同时受电弓与外部气流隔绝后,降弓产生的气动噪声被消除,从而减小了轨道车辆运行中产生的噪音。
