[0002] The roof of a rail vehicle is a specific structure, which consists of a middle roof body, which is fixed to the steel structure of the vehicle body. This roof structure is usually composed of a metal panel with a layer of decorative material laid on it. The middle roof of this structure is easy to form and install, and can also be made of a larger width, which visually increases the width of the passenger compartment. In addition, since the surface of the middle roof is made of metal panels, its surface treatment can be diversified, thereby achieving different visual effects.

[0003] Traditional rail vehicle center top plate assemblies are processed by one-piece molding and spraying. They cannot be disassembled and are heavy. When damaged, they can only be replaced as a whole. Sound insulation is achieved by using sound insulation cotton, but the sound insulation cotton has poor thermal insulation performance and insufficient overall freedom. Traditional rail vehicle center top plate assemblies have a single connection method. Due to the different vehicle center top connection methods, specific center top plate assemblies can only be rotated according to the vehicle center top connection method. Utility Model Content

When damaged, it can only be replaced as a whole, and sound insulation cotton is used to achieve sound insulation, but the sound insulation cotton has poor heat insulation performance and insufficient overall freedom. The connection method of the top plate assembly in traditional rail vehicles is single. Due to the different connection methods of the vehicle top, only a specific top plate assembly can be rotated according to the vehicle top connection method.

[0005] In order to solve the above technical problems, the technical solution of the utility model is a rail vehicle middle top plate assembly, including a middle top plate shell and a plurality of positioning shafts, the plurality of positioning shafts are respectively installed on the upper wall surface of the middle top plate shell, the upper wall surfaces of the plurality of positioning shafts are respectively installed with guide screws, the inner wall surface of the middle top plate shell is provided with a plurality of guide grooves, the outer wall surface of the middle top plate shell is installed with a film layer, the inner wall surfaces of the plurality of guide grooves are installed with a sandwich structure, the two side surfaces of the middle top plate shell are installed with a first fixing structure, and the two side surfaces of the middle top plate shell are installed with a second fixing structure.

[0006] As a further solution of the utility model: the sandwich structure includes: a noise reduction layer, a heat insulation layer, a limiting layer, a plurality of limiting guide plates, a plurality of protective layers, a plurality of protective sliders and a plurality of locking blocks; the noise reduction layer is sleeved on the outer wall surfaces of a plurality of positioning shafts, the heat insulation layer is sleeved on the outer wall surfaces of a plurality of guide screws, the limiting layer is sleeved on the outer wall surfaces of a plurality of guide screws, a plurality of the limiting guide plates are respectively installed on the inner wall surfaces of a plurality of guide grooves and are connected to the limiting layers, a plurality of the protective layers are respectively sleeved on the outer wall surfaces of a plurality of guide screws and are pressed on the limiting layers, a plurality of the protective sliders are respectively installed on the inner wall surfaces of a plurality of guide grooves and are respectively connected to the plurality of protective layers, and a plurality of the locking blocks are respectively sleeved on the outer wall surfaces of a plurality of guide screws.

[0007] As a further solution of the utility model: the first fixed structure includes: two groups of load-bearing hinges, two steering rods and two fixed plates; the two groups of load-bearing hinges are respectively installed on the two side surfaces of the middle top plate outer shell, the two steering rods are respectively installed on the inner wall surfaces of the two groups of load-bearing hinges, and the two fixed plates are respectively mounted on the outer wall surfaces of the two steering rods.

[0008] As a further solution of the utility model: the second fixing structure includes: four positioning ear seats, four locking ear seats, four locking nuts, two support plates and two load-bearing plates; the four positioning ear seats are respectively installed on the two side surfaces of the middle top plate outer shell, the four locking ear seats are respectively connected to the lower wall surfaces of the four positioning ear seats, the two support plates are respectively installed on the lower wall surfaces of the four locking nuts, and the two load-bearing plates are respectively installed on the two side surfaces of the two support plates.

[0012] The utility model adopts the above technical solution, and has the following advantages compared with the prior art:

[0013] The sandwich structure achieves high strength and light weight, and the noise reduction layer and the heat insulation layer achieve better sound insulation and heat insulation performance. The sound insulation cotton is optimized and cancelled. The traditional painting scheme is replaced by sticking film on the film layer. The pattern of the film can be changed at any time, which is more beautiful and diversified. It solves the problem that the top plate assembly in traditional rail vehicles adopts one-piece molding and spraying processing, cannot be disassembled, and has a large mass. When damaged, it can only be replaced as a whole.
