Abstract

The embodiment of the invention provides a carriage and a railway vehicle. The carriage comprises a carriage body, a cover plate and seats. The carriage body comprises a bottom frame and a supporting frame, the supporting frame is located above the bottom frame and arches upwards, and a mounting space used for mounting the bogie is formed between the bottom frame and the supporting frame. The cover plate covers the upper surface of the supporting frame. The seat is arranged on the cover plate and comprises a backrest, a cushion, a supporting piece and a mounting piece. And the backrest and the cushion are fixed on the supporting piece. And the supporting piece is inserted and matched with the mounting piece. The mounting piece is connected with the supporting frame and the cover plate. By the adoption of the scheme, the seat is simple in overall structure and convenient to mount and dismount, light weight of a carriage can be achieved, cost is saved, and meanwhile mounting efficiency is improved.

Description

technical field [0001] The present application relates to rail train technology, in particular, to a carriage and a rail vehicle. Background technique [0002] Passenger seats are mandatory equipment on rail vehicles. With the vigorous development of urban rail vehicles, the requirements for the structure and aesthetics of the seat system are getting higher and higher, which requires not only fast installation and disassembly, but also aesthetics. In order to facilitate passengers to get on and off the train, no platform is set on the ground where the low-floor vehicles park. The seat can only be installed above the bogie. A conventional seat installation structure on a rail vehicle includes: a seat, a wheel box cover, a frame, and a car body. The car body with the bogie part is arched upwards to provide installation space for the bogie; the frame is erected and fixed on the car body to provide a support point for the seat; the wheel box cover plays a decorative role to c...
