[0002] The interior decoration of urban rail subway vehicles is used to cover the body structure and ensure the beauty of the passenger compartment. The middle roof plate is arranged on the top of the body to cover the roof structure. The interior decoration installation structure of the middle roof part of the traditional subway vehicle is to fix the middle roof plate on the secondary frame by screws. The secondary frame is a frame structure that is crisscrossed and connected. The entire frame structure runs through the entire roof and is arranged above the entire ceiling interior decoration. The secondary frame needs to be fixed with hangers at both ends and in the middle. There are a large number of hangers, all of which are connected to the body by welding, and the welding amount is very large. In addition, the middle roof plate, grille, secondary frame, lamp installation profile, etc. are supplied as loose parts, and all need to be installed on site. The installation is cumbersome and the adjustment workload is large. Thirdly, in the prior art, lamps are generally installed in the side roof plate and the middle roof plate, and the installation structure of the lamps is also relatively complicated. The maintenance and replacement of lamps often requires the removal of the middle roof plate or the side roof plate, which makes maintenance and replacement time-consuming and labor-intensive. In addition to traditional lamps, the middle roof plate structure cannot meet the needs of installing atmosphere lights, and cannot meet the needs of personalization and innovation.
