An integral type flat top plate structure of a railway vehicle is characterized in that the integral type flat top plate structure comprises an inner light-transmitting PC plate, an outer light-transmitting PC plate and a middle interlayer foam honeycomb, a decorative film adheres to the exposed face of the outer light-transmitting PC plate, light-transmitting holes are locally formed in a spotlight area of the decorative film, and an embedded type threaded sleeve is installed on the back face of a flat top plate and used for installing and fixing a spotlight body of a lighting system. A spotlight hole is formed in the bottom of the threaded sleeve, and a fastening nut is arranged at the tail of the spotlight and used for fixing an optical fiber light source connected into the lamp body. On the premise that the strength and the rigidity of the flat top plate are guaranteed, the overall weight can be effectively reduced, and the purpose of reducing the weight of the whole vehicle is achieved. The embedded threaded sleeve is installed on the flat top plate and used for installing and fixing the spotlight body of the intelligent lighting system, the situation that holes are additionally formed in the flat top plate for spotlight installation is avoided, meanwhile, the spotlight body and the top plate are integrated, and the integrity and attractiveness of the flat top plate are improved.
一种轨道车辆整体式平顶板结构,其特征在于:包括内外两侧透光PC板和中间夹层泡沫蜂窝,外侧透光PC板外露面粘贴有装饰膜,装饰膜在射灯区域局部增加透光孔,平顶板背面装有嵌入式螺纹套,用于灯光系统射灯灯体的安装固定,螺纹套底部开有射灯灯孔,射灯尾部设有紧固螺帽用于固定接入灯体的光纤光源。本发明的平顶板在保证强度和刚度的前提下,能有效降低整体重量,实现整车减重的目的。在平顶板上安装嵌入式螺纹套,用于智能灯光系统射灯灯体的安装固定,避免了平顶板为射灯安装增加开孔,同时将灯体与顶板集成为一体,提高了平顶板的完整性与美观性。
