Hat brim-shaped railway vehicle top cover and vehicle body structure

Abstract

The invention discloses a cap-brim-shaped rail vehicle top cover and a vehicle body structure, and belongs to the technical field of rail traffic vehicle structures, and the cap-brim-shaped rail vehicle top cover comprises a flat cover plate which is of a plate-shaped structure and is connected with a machine room; the L-shaped plate is of an L-shaped plate-shaped structure, the L-shaped plate is connected with the flat cover plate, and the end, away from the flat cover plate, of the L-shaped plate is a profiling face which is perpendicular to the flat cover plate and extends in the direction away from the machine room; the convex cover plate is connected with the L-shaped plate along the edge of the profiling face of the L-shaped plate to form a cavity extending in the direction away from the mechanical room, a vertical plate is arranged on the side, away from the flat cover plate, of the convex cover plate, and an extending part arranged in a U shape along the inner wall of the convex cover plate is arranged at the tail end of the side, facing the mechanical room, of the convex cover plate. The extension part is provided with a plurality of inner side installation bases used for being connected with a machine room. The cap-brim-shaped railway vehicle top cover and vehicle body structure can adapt to arrangement of equipment with different heights in a mechanical room, and the space utilization rate and continuity are improved while the sealing performance is ensured.
