Description
Technical field
The present invention relates to high-speed track locomotive technology fields also to relate to more specifically to a kind of railway vehicle cab
And a kind of rail vehicle.
Background technique
As China's EMU is gone abroad, the passive security performance of EMU is increasingly paid attention to, in order to enter Europe
Continent market, the passive security performance of EMU are required to meet the requirement of higher standard, wherein the requirement for drivers' cab be exactly
When vehicle is collided with higher speed and barrier, the living space of driver is avoided to be broken into, while from also guaranteeing to rush
Hitting acceleration cannot be too high.
When colliding for EMU with other rail vehicles or similar burst sexual dysfunction, usually pass through special buffering
Device absorbs energy, and car body does not deform generally.But for EMU intersection and large-scale deformable barrier (such as
Truck, engineering truck etc.) when colliding, the buffer unit position of EMU front end is lower, and barrier is higher, before EMU
The buffer unit at end can not effectively play energy-absorbing function, at this moment just need the structure by drivers' cab itself to absorb energy, and guarantee
The living space of drivers' cab.
In particular for the motor-car head vehicle of power-centralized type, itself has light-weighted requirement, and needs to have enough
Intensity guarantees guarantee of the drivers' cab to the absorption of collision and internal living space, and conventional design in the prior art is difficult to full
The above-mentioned each demand for security of foot.
It is difficult to take into account light weight in conclusion how to efficiently solve the design of the high speeds rail vehicle head drivers' cab such as EMU
The technical problem of the demand of change and high intensity etc., is current those skilled in the art's urgent problem.
Summary of the invention
In view of this, the first purpose of this invention is to provide a kind of railway vehicle cab, rail vehicle driver
The structure design of room can efficiently solve the design of the high speeds rail vehicle head drivers' cab such as EMU be difficult to take into account lightweight and
The technical issues of demand of high intensity, a second object of the present invention is to provide a kind of rails including above-mentioned railway vehicle cab
Road vehicle.
In order to reach above-mentioned first purpose, the present invention is provided the following technical solutions：

Specific embodiment
The embodiment of the invention discloses a kind of railway vehicle cabs, to solve the high speeds rail vehicle head such as EMU department
The design of machine room is difficult to take into account the technical problem of demand of lightweight and high intensity etc..
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-Fig. 4 is please referred to, Fig. 1 is the external structure schematic diagram of railway vehicle cab provided in an embodiment of the present invention；Fig. 2
For the partial structural diagram of the middle portion connecting structure of railway vehicle cab provided in an embodiment of the present invention；Fig. 3 be Fig. 2 in
The configuration schematic diagram of portion connecting structure；Fig. 4 is the drivers' cab front wall of railway vehicle cab provided in an embodiment of the present invention
Structural schematic diagram.
Wall 3 after railway vehicle cab provided in an embodiment of the present invention, including drivers' cab front wall 1, drivers' cab, and support
It is connected to the middle portion connecting structure 2 after the drivers' cab front wall 1 and drivers' cab between wall 3；The middle portion connecting structure 2 is cut in change
Face ring shape, including it is interlaced be in netted crossbeam 2-1 and stringer 2-2, be made of the crossbeam 2-1 and stringer 2-2 netted
Inner supporting structure 2-3 is additionally provided in space.
The drivers' cab provided in this embodiment is made of front wall, Hou Qiang and middle portion connecting structure 2, and front wall, which provides, to be had enough
The front-end protection of intensity, middle portion connecting structure 2 uses the criss-cross webbed structure of supporting beam structure, to guarantee drivers' cab
External structure intensity, while meeting light-weighted locomotive itself and requiring, reach the maximization that girder construction intensity utilizes, passes through girder construction
Metal plate and assembly to constitute variable cross-section cyclic annular, meet the space requirement of drivers' cab, and this structure itself be also capable of providing it is bigger
The support of intensity；Stable reticular structure itself can provide biggish support strength, however to reinforce reticular structure sheet
Body stability enables being unlikely to deform for reticular structure in itself, prevents the deformation loss support strength due to web frame itself, further
Inner supporting structure 2-3 is set in the mesh space that beam is staggered to form, when netted middle portion connecting structure 2 is collided and is pressurized, phase
Mutual staggered crossbeam 2-1 and stringer 2-2 is due to being pressurized, in fact it could happen that certain crossbeam 2-1 becomes with what certain stringer 2-2 stagger angle changed
Gesture, the interior protective space that this trend may cause middle portion connecting structure 2 are compressed, and inner supporting structure 2-3 can occur
Adjacent crossbeam 2-1 and stringer 2-2 are supported when this extruding trend, the mesh space for preventing the two from surrounding is squeezed and deformed, therefore
It can enable that netted cross structure is stronger, is not susceptible to stress deformation, effective protection drivers' cab internal security space.To sum up institute
