This utility model discloses a battery cover, a roof structure, and a monorail shunting machine. The battery cover includes a frame, a body, a cover, a first waterproof structure, multiple second waterproof structures, and a third waterproof structure. The bottom of the frame is fixedly connected to the top of the carriage. The body includes multiple panels, which are arranged sequentially to enclose a polygonal cavity. Each panel is detachably and fixedly connected to the frame. The cover is placed on top of each panel and is detachably and fixedly connected to the frame. The first waterproof structure is located at the seam between each panel and the carriage. Each of the second waterproof structures is located at the seam between adjacent panels. The third waterproof structure is located at the seam between the cover and each panel. The advantages of this utility model are that the battery cover can simultaneously meet the requirements of a detachable top panel, removable four-sided coverings, and waterproofing.

A light mass transit vehicle sidewall assembly and associated long girders are provided that are lightweight, strong, safe, and easily adaptable to include panels in the assembly, and that are lighter than typical long girders while maintaining adequate stiffness and strength required to support the roof and associated components attached to the roof and securely connect to the light mass transit vehicle sidewall assembly.

This application discloses a highly integrated roof assembly for rail transit vehicles, relating to the technical field of rail transit vehicle components. It includes a main roof structure composed of an upper panel, a lower panel, and a core layer. A load-bearing frame is integrated with the main roof structure to support and transfer loads to the vehicle body. Air ducts and cable trays are located inside the main roof structure for ventilation and electrical wiring harness arrangement, respectively. A mounting frame is located on top of the main roof structure, with several mounting interfaces for installing air conditioning units and power battery modules. Additionally, components such as heat dissipation plates are provided to assist in heat dissipation. This application achieves a high degree of functional integration. Through a rational structural design, it integrates multiple roof functions while ensuring good ventilation and heat dissipation performance, making the roof structure more stable and reliable.

The present application relates to the field of rail vehicle body roof forming, and particularly discloses a grid wallboard composite roof structure based on automatic fiber placement process, a rail vehicle and a manufacturing method thereof. The process realizes accurate placement of continuous fibers on a complex curved surface through an automatic fiber placement device, and forms a large integrated roof part with a grid reinforcing structure. The grid wallboard composite roof structure comprises a composite skin layer and a fiber foam sandwich layer. The fiber foam sandwich layer comprises hoop grid ribs, transverse grid ribs and longitudinal grid ribs. The transverse grid ribs and the longitudinal grid ribs are arranged in the hoop grid ribs, and the hoop grid ribs, the transverse grid ribs and the longitudinal grid ribs are connected to form a continuous closed placement path grid. High-density foam is arranged in the grid intersection node area, and low-density foam is arranged in the grid unit area. Large-size grids are arranged in the central area of the roof, and small-size grids are arranged in the edge and connecting area of the roof. The present application is particularly suitable for batch manufacturing of large roof parts of high-speed rail, subway and light rail.

This invention relates to the field of vehicles, providing a roof reinforcement structure, a carriage, and a rail vehicle. The roof reinforcement structure includes a first support plate, a second support plate, a column structure, and a cylindrical structure. The outer wall of the column structure has a protrusion, and the inner wall of the cylindrical structure has a recess for engaging with the protrusion. Both the column structure and the cylindrical structure are positioned between the first and second support plates, with one connected to the first support plate and the other to the second support plate. The interlocking connection between the column structure and the cylindrical structure eliminates the need for through holes in the first and second support plates for connecting components, thus ensuring the sealing and structural strength of the first and second support plates. During assembly and disassembly, the tightening process is eliminated, making operation more convenient and increasing efficiency.
