The roof structure comprises a top plate assembly and two roof edge beams located on the two sides of the top plate assembly respectively, a mounting rib plate is connected to the bottom face of the top plate assembly, the edges of the two sides of the mounting rib plate are connected to the bottom face of the top plate assembly respectively, and a through mounting cavity is defined by the mounting rib plate and the top plate assembly; a sound insulation layer is arranged in the mounting cavity. According to the car roof structure, the mounting rib plate is connected to the bottom face of the top plate assembly, the through mounting cavity is formed in the space between the mounting rib plate and the top plate assembly, the sound insulation layer arranged in the mounting cavity facilitates the sound insulation and noise reduction effects, and transmission of noise of an air conditioning unit and electrical equipment above the top plate assembly to the interior of a car below can be reduced; and meanwhile, the assembling efficiency of the roof structure is improved, more space is provided for installation of electrical equipment above the top plate assembly, arrangement of an air conditioning unit and the electrical equipment is facilitated, and the space utilization reasonability is improved.
本发明提供了一种车顶结构及轨道车辆,包括顶板组件和两个分别位于顶板组件两侧的车顶边梁,顶板组件的底面上连接有安装筋板,安装筋板的两侧边缘分别连接于顶板组件的底面上、且安装筋板与顶板组件之间围合成贯通的安装腔,安装腔内设有隔音层。本发明提供的车顶结构,在顶板组件的底面上连接有安装筋板,安装筋板与顶板组件之间的空间形成贯通的安装腔,设置在安装腔内的隔音层便于实现隔音降噪的效果,可减小顶板组件上方空调机组及电气设备的噪音向下方车内的传递,便于保持车内环境的安静,同时提高车顶结构的装配效率,顶板组件上方为电气设备的安装提供更多提供更多的空间,便于进行空调机组和电气设备的布设,提高空间利用的合理性。
