Abstract

Disclosed is a weight lightened sleeping berth which comprises a framework frame, support legs, a support bottom plate and foam material, and is characterized in that the support bottom plate is an aluminum honeycomb plate; the sections of the framework frame and support legs are groove-shaped sections; the support bottom plate is mounted in the groove-shaped section of the framework frame; foam material is mounted on the support bottom plate and the framework frame. The utility model adopts the finite element analysis method to process strength analysis for designing and improving the sleeping berth structure in an optimizing way; aluminum alloy groove-shaped sections are used as the sections of the framework of the sleeping berth and the support legs; meanwhile, the plywood structure of the support bottom plate is replaced by the aluminum honeycomb plate structure; the support bottom plate is mounted on the groove-shaped section of the framework frame; not only the obvious weight reduction effect is realized, but also the force application becomes more reasonable; the bearing and application service life requirements of the sleeping berth are satisfied; compared with the weight of the sleeping berth in the prior art, the weight is reduced by 17.4%; the round spring damping structure is removed to solve the great noise problem in the running process of the train.

Description

The lightweight sleeping berth

Technical field:

The utility model relates to a kind of sleeping berth, especially relates to a kind of high speed cushioned berth sleeping car lightweight sleeping berth.

Background technology:

At present, the cushioned berth sleeping car sleeping berth adopts steel plate die mould welded framework, and the foam support base plate is a veneer sheet, and the strength of material surplus is big, and weight is bigger, and is stressed unreasonable, can't satisfy high speed train weight-saving demand, and the easy moisture absorption corrosion of veneer sheet, influences service life; Noise is bigger when adopting circle spring shock-damping structure to cause train operation.

Summary of the invention:

Technical problem to be solved in the utility model is: bigger at present cushioned berth sleeping car sleeping berth weight, the bigger problem of noise during train operation, utilize that aluminum alloy proportion is little, the corrosion-resistant material characteristic, development is suitable for the sleeper structure of aluminum alloy, cancellation veneer sheet and circle spring shock-damping structure, expendable weight improves load-carrying capacity, comfort property and service life.

For solving the problems of the technologies described above, the utility model provides a kind of lightweight sleeping berth, comprise skeleton frame, supporting leg, supporting baseplate, foam, it is characterized in that: supporting baseplate is an aluminum honeycomb panel, the section of skeleton frame and supporting leg is the grooved section, supporting baseplate is installed in the grooved section of skeleton frame, and foam is installed on supporting baseplate and the skeleton frame.

The utility model utilizes limited element analysis technique to carry out strength analysis sleeper structure is optimized design and improvement, adopt aluminum alloy grooved section as sleeping berth skeleton and supporting leg section, supporting baseplate changes the aluminum honeycomb panel structure into by veneer sheet simultaneously, supporting baseplate is installed in the skeleton frame grooved section, not only played tangible weight loss effect, the while more reasonable stress, the carrying and the requirement in service life of sleeping berth have been satisfied, the existing sleeping berth of weight ratio has reduced 17.4%, cancellation circle spring shock-damping structure, the big problem of noise when having solved train operation.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cutaway view along A-A line among Fig. 1;

Fig. 3 is the cutaway view along B-B line among Fig. 1.

The specific embodiment:

With reference to Fig. 1, Fig. 2, Fig. 3, the utility model comprises skeleton frame 2, supporting leg 1, supporting baseplate 3, foam 4, supporting baseplate 3 is an aluminum honeycomb panel, the section of skeleton frame 2 and supporting leg 1 is the grooved section, supporting baseplate 3 is installed in the grooved section of skeleton frame 2, supporting baseplate 3 and supporting leg 1 riveted joint, foam 4 is installed on supporting baseplate 3 and the skeleton frame 2.

Claims

1, a kind of lightweight sleeping berth, comprise skeleton frame, supporting leg, supporting baseplate, foam, it is characterized in that: supporting baseplate is an aluminum honeycomb panel, the section of skeleton frame and supporting leg is the grooved section, supporting baseplate is installed in the grooved section of skeleton frame, and foam is installed on supporting baseplate and the skeleton frame.
