Sleeping-berth structure capable of realizing seat-berth conversion and sleeping berth carriage with same

Abstract

The invention relates to a sleeping-berth structure capable of realizing a seat-berth conversion and a sleeping berth carriage with the same. The sleeping-berth structure comprises a berth body and a berth support; the berth body comprises a main body and a turning body, the turning body is arranged at the inner side of the main body, the turning body is rotatably connected to a compartment wall, the main body is slidably connected with the berth support through a sliding mechanism, and the turning body can turn upward to form a backrest. The sleeping-berth structure is simple and practical; only by turning the turning body and moving the main body can the seat-berth conversion be achieved, the operation is very convenient. Besides, when used as a berth, the turning body and the main body can both serve as a berth surface of the berth, thus the berth surface is widened, and the use of the berth is more comfortable for a passenger.

Description

technical field [0001] The invention relates to a sleeping berth structure, in particular to a sleeping berth structure which can realize the conversion between sitting and lying down, and at the same time relates to a sleeping car compartment equipped with the sleeping berth structure. Background technique [0002] In the sleeper compartments of railway vehicles, there are usually two or three layers of berths installed on the partition wall. The sleepers usually used are mostly fixed structures, which cannot be turned over or moved. The berth and the middle berth are free, while the lower berth is temporarily used as a seat for passengers. However, due to the wide berth in this case, when passengers sit on the berth, their backs can only lean against the partition wall, and there is no waist support. very uncomfortable.

AI Technical Summary

Problems solved by technology

[0002] In the sleeper compartments of railway vehicles, there are generally two or three layers of berths installed on the partition wall. The sleepers usually used are mostly fixed structures, which cannot be turned over or moved. The berth and the middle berth are empty, and the lower berth is temporarily used as a seat for passengers. However, due to the wide berth in this case, when passengers sit on the berth, their backs can only lean against the partition wall, and there is no waist support. very uncomfortable

In addition, if only two layers of paved carriages are installed, the number of people that can be accommodated in one carriage is greatly reduced. When the number of passengers on railway vehicles increases sharply on special days such as Spring Festival travel, the existing sleeper carriages take up a lot of resources , increasing the burden on the railway sector and transportation costs

[0003] In the prior art, in order to realize the conversion between the seat and the sleeper, an auxiliary pavement is added, the auxiliary pavement is connected to the main pavement by a hinge, the auxiliary pavement is folded upwards to form the pavement of the sleeper, and it is folded downward when not in use. Used as a seat, although this structure is simple, its load-bearing performance is weak, and it is very inconvenient to turn over

In the patent No. 200720000976.4 "a sleeper with a pull-out mechanism", a sleeper is disclosed, including a bed and a backrest, a bed with legs under the bed, and a linkage rod between the bed and the backrest , there is a supporting frame under the paving, front and rear rollers are arranged under the supporting frame, and a leg chute is set on the paving legs, the paving and the backrest are linked, and the paving is moved by pulling, and at the same time, the bottom of the backrest can be moved toward the The front is raised and tilted to make people feel more comfortable when sitting, but the width of the pavement of this structure is constant. When used as a sleeper, the gap between the pavement and the partition wall is empty, which affects the comfort of passengers. sex, also wastes a certain amount of space
