Composition of a new type of railway passenger car longitudinal sleeper

Abstract

The invention relates to a novel passenger train longitudinal sleeper composition. The longitudinal sleeper composition consists of two push-pull seats symmetrically arranged; the push-pull seats include four parts of rotating mechanisms, backrest and headrest overturning mechanisms, sleeper push-pull sliding mechanisms and armrest compositions, wherein the rotating mechanisms include lower support frames, air spring mounting bases, air springs, eccentric rotating plates, rotating fixed bases, overturning backrests and fixed slide rails; the backrest and headrest overturning mechanisms are arranged above the overturning backrests; the sleeper push-pull sliding mechanisms are mounted on fixed slide rails, and perform push-pull actions corresponding to the fixed slide rails; and the armrest compositions are arranged on one sides far from windows, and are fixed on the lower support frames of the rotating mechanisms. The sleeper composition is a sitting and sleeping dual-purpose device, can guarantee the sitting comfort of passengers in a sitting state and a sleeping state, and guarantees personal safety of the passengers under the condition of vehicle operation accidents.

Description

technical field [0001] The invention belongs to the field of railway passenger car parts, and in particular relates to a novel railway passenger car longitudinal sleeper composition. Background technique [0002] The sleeping berth is the main facility in the sleeping berth of a railway passenger car. It is used for passengers on medium and long-distance travel or to lie down and rest when they are tired or when the vehicle is driving at night, so as to avoid the fatigue of the journey. The sleeping berths installed in the existing railway passenger cars are usually fixed structures. The pavement and legs of the berth are connected and fastened with the partition wall, side wall panels and floor welds of the passenger compartment of the vehicle through fasteners, and there is no movement between the bedding and the legs of the berth. The mechanism is usually arranged along the vehicle width direction and perpendicular to the window. This sleeper has the following disadvanta...

AI Technical Summary

Problems solved by technology

This sleeper has the following disadvantages: (1) when the passenger is in a sitting position, the sleeper has a wider surface, and the seat depth is larger when riding, and there is no support behind the back, or the back rests on the partition wall, and the ride comfort is poor; (2) sleeper The layout direction is perpendicular to the window. When there are multiple passengers, at most one passenger can sit by the window, and the rest of the passengers have nowhere to put their arms; (3) When the passengers lie down to sleep, the vehicle operation direction is perpendicular to the passenger’s lying direction, and the vehicle shakes 1. In the case of emergency braking, passengers are likely to fall off the sleeper berth, causing accidental injury
