The embodiment of the invention relates to the technical field of railway vehicles, in particular to a railway vehicle and a connecting structure and connecting method of an edge top plate and a side wall plate of the railway vehicle. According to the connecting structure, a rain eave and a plurality of through holes are arranged at the bottom end of the edge top plate; the top edges of the through holes are lower than the top edge of the rain eave; and the bottom end of the edge top plate is welded to the outer surface of the top of the side wall plate, and a weld joint for connecting the edge top plate and the side wall plate is located on the edge of the through hole. According to the connecting structure, the edge top plate is welded to the side wall plate through the welding seam formed in the through hole, the welding seam is shielded through the rain eave, the appearance attractiveness of the whole vehicle is improved, the welding seam does not need to be shielded through an air conditioner cover plate, and meanwhile rainwater flowing down from the vehicle roof can be guided through the rain eave.

    本申请实施例涉及轨道车辆技术领域,具体地,涉及一种轨道车辆及其边顶板与侧墙板的连接结构和连接方法。该连接结构在边顶板的底端设置有雨檐和多个通孔;通孔的顶缘高度低于雨檐的顶边高度;边顶板的底端焊接连接于侧墙板的顶部外表面,用于连接边顶板和侧墙板的焊缝位于通孔的边缘。该连接结构通过形成于通孔内的焊缝将边顶板焊接于侧墙板,并通过雨檐对焊缝进行遮挡,不仅提高了整车的外观美感,而且无需通过空调罩板遮挡焊缝,同时通过雨檐还能对车顶流下的雨水进行导流。
