The invention relates to the field of vehicles, and provides a ceiling reinforcing structure, a carriage and a railway vehicle. The ceiling reinforcing structure comprises a first supporting plate, a second supporting plate, a column structure and a cylinder structure. Wherein the outer wall of the cylinder structure is provided with a protruding part, the inner wall of the cylinder structure is provided with an inner concave part used for being clamped with the protruding part, the cylinder structure and the cylinder structure are both arranged between the first supporting plate and the second supporting plate, one of the cylinder structure and the cylinder structure is connected with the first supporting plate, and the other one of the cylinder structure and the cylinder structure is connected with the second supporting plate. Through clamping connection of the column structure and the barrel structure, through holes allowing the connecting pieces to penetrate do not need to be formed in the first supporting plate and the second supporting plate, and therefore the sealing performance and the structural strength of the first supporting plate and the second supporting plate can be guaranteed. In the disassembly and assembly process, the screwing process is omitted, operation is more convenient, and the disassembly and assembly efficiency is higher.

    本发明涉及车辆领域,提供一种顶棚加强结构、车厢及轨道车辆。顶棚加强结构包括第一支撑板、第二支撑板、柱体结构和筒体结构;其中,柱体结构的外壁设有凸起部,筒体结构的内壁设有用于与凸起部相卡合的内凹部,柱体结构和筒体结构均设置在第一支撑板和第二支撑板之间,并且柱体结构和筒体结构二者中的一者与第一支撑板连接,另一者与第二支撑板连接。通过柱体结构和筒体结构的卡合作用连接,无需在第一支撑板和第二支撑板上开设供连接件穿过的通孔,因此能够保证第一支撑板和第二支撑板的密封性以及结构强度。在拆装过程中,省去旋拧过程,操作更便捷,拆装效率更高。
