The vehicle body structure comprises a vehicle roof, side walls, a bottom frame and end walls, the tops of the side walls are connected with the vehicle roof, the bottoms of the side walls are connected with the bottom frame, and the end walls are arranged at the two ends of the bottom frame in the extending direction and connected with the vehicle roof and the bottom frame correspondingly; wherein the roof, the side walls, the underframe and the end walls are all of sandwich structures. According to the vehicle body structure, the vehicle roof, the side walls, the bottom frame and the end walls are all of the interlayer structures, compared with an existing vehicle body structure which adopts a plate beam connecting structure, the number of parts is greatly reduced, the weight of the vehicle body structure can be reduced, and the lightweight design of the vehicle body structure is achieved; meanwhile, the manual operation amount of workers can be reduced, and the automatic production efficiency is improved.

The invention discloses a vehicle body structure and a railway vehicle. In the vehicle body structure, the size of the cargo inlet / outlet along the length direction of the vehicle body is greater than 3m; the first frame provided with the cargo inlet and outlet comprises a traction beam, a lower side beam and a traction beam which are sequentially connected in the length direction of the vehicle body, the middle section area of the lower side beam limits the lower boundary of the cargo inlet and outlet, the lower side beam is in a channel steel type, an opening of the channel steel type lower side beam faces the first frame on the opposite side, and the upper boundary of the channel steel type lower side beam is horizontally arranged. The size of the middle area of the channel steel type lower side beam in the height direction of the vehicle body is larger than that of the two ends of the channel steel type lower side beam in the height direction of the vehicle body, and a section with the size monotonically increasing in the height direction of the vehicle body does not exist from the position, with the largest size in the height direction of the vehicle body, of the channel steel type lower side beam to any end area. The first frame on the side provided with the goods inlet and outlet further comprises a lower side beam inner sealing plate for sealing an opening of the channel steel type lower side beam. The device is suitable for transportation of large-size goods.

The invention relates to a rail vehicle (2a, 2b, 2c) for transporting passengers which comprises at least one car body (4), a passenger compartment (34) situated in the car body (4), an underfloor region (26), an inner ceiling region (32), and a plurality of device containers (44, 44a, 44b, 44c) for receiving vehicle components, the passenger compartment (34) comprising a first end wall region (36) and a second end wall region (38), which is situated opposite the first end wall region (36). In order to enable a great configuration freedom for the passenger compartment (34), it is provided that each device container (44, 44a, 44b, 44c) of the rail vehicle (2a, 2b, 2c) is arranged in one of the mentioned regions (26, 32, 36, 38).

To provide a railway vehicle in which both a partition panel and a ceiling panel can be easily removed.SOLUTION: The ends of a partition panel and a ceiling panel are positioned at the corners of a passageway 30, and a ceiling frame 40 has a flat vertical piece 40a and a flat horizontal piece 40b bent at a substantially right angle from the upper end of the vertical piece 40a. The vertical piece 40a is positioned on the back side of the partition panel 31 facing the passageway 30, and the horizontal piece 40b is positioned on the back side of the ceiling panel 32 facing the passageway 30. The partition panel 31 is detachably fixed to the vertical piece 40a with bolts 53 and floating nuts 54 either directly or via a partition joint member 51 joined to the partition panel 31, and the ceiling panel 32 is detachably fixed to the horizontal piece 40b with bolts 63 and floating nuts 64 either directly or via a ceiling joint member 61 joined to the ceiling panel 32.SELECTED DRAWING: Figure 4
