Problems solved by technology

[0004] When the collision occurs, the anti-climbing device has completed the energy absorption function, but if the collision process is still in progress, the cab structure will be further compressed, but the deformation of the cab structure in the prior art is uncontrollable, which will cause the cab to play a load-bearing role. Under the action of the impact force, the structure warps upward or downward, and there is still a risk of climbing, which endangers the driver's life.

Embodiment 2

[0112] This embodiment provides a rail vehicle, which includes a car body and a driver's cab, wherein the driver's cab is connected to one end of the car body.

[0113] The driver's cab in this embodiment has the same structure as that of the rail vehicle driver's cab provided in the first embodiment, and can bring about the same or similar technical effects, which will not be described here one by one. For details, please refer to the description of the first embodiment.

[0114] Wherein, bolts can be set on the skeleton structure 2 and the chassis structure 1 of the driver's cab. When installing, the entire driver's cab is assembled and welded first, and then the driver's cab and the vehicle are connected by the bolts on the skeleton structure 2 and the chassis structure 1. The body is connected together, making and assembling more convenient. After the collision, the replacement and maintenance of the overall structure of the driver's cab can be conveniently carried out.

Abstract

The invention provides a rail vehicle cab and a rail vehicle. The cab of the rail vehicle comprises a skeleton structure and a chassis structure welded at the bottom of the skeleton structure. The chassis structure comprises two symmetrically arranged side beams, a chassis back plate and a front plate; The front end face of the front end plate is provided with anti-creep teeth, and the chassis back plate, the front end plate and the two side beams are enclosed by a receiving space with an energy-absorbing structure, and the energy-absorbing structure is connected between the front end plate and the chassis back plate; The skeleton structure comprises a skeleton back plate, a window side beam, a window lower cross beam and a window lower side beam; The top end of the window side stand beamis connected with the backboard of the frame, the bottom end of the window side stand beam is connected with the side beam, and the window side stand beam, the window lower cross member and the windowlower side member are provided with at least two bending points protruding toward the exterior of the cab, and the bending points are formed as preset deformation points of the crushing deformation of the frame structure, thereby effectively preventing the crawling car from occurring.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a driver's cab of a rail vehicle and the rail vehicle. Background technique [0002] There are many types of rail vehicles, mainly including: underground subway trains, express rail and light rail trains connecting the city center and suburbs, and trams that shuttle through the bustling areas of the city. [0003] The anti-collision passive safety design of rail vehicles is an important guarantee for the safe operation of vehicles. The rail vehicle includes a car body and a driver's cab connected to one end of the car body. The driver's cab includes an underframe structure and a skeleton structure connected to the underframe structure. In order to prevent the vehicle from climbing, the prior art installs an anti-climbing device, specifically, the anti-climbing device is installed on the front wall of the driver's cab or the front end of the chassis structure, that is, the ...
