Description

Technical Field

[0001] The utility model relates to a multifunctional railway passenger car movable window structure, belonging to the technical field of railway vehicle body parts. Background Art

[0002] Most of the windows of railway passenger cars are separate glass windows, and the blinds, screens and glass windows are not integrated into a movable window structure. The blinds, screens and glass windows installed on railway passenger cars in the prior art are mostly fixed on the car body separately, and cannot realize functions such as up and down sliding and limiting. Most of the prior art uses a double-wire box spring balancer to hang the car windows (including glass windows, blinds, etc.) to realize the up and down sliding of the car windows along the track in the window frame. The function of the double-wire box spring balancer is to control the left and right balance when the car windows slide up and down.

[0003] With the increasing requirements for the safety, practicality and window ventilation in railway passenger cars, it is required that the blinds, screens and glass windows be integrated into a movable window structure in railway passenger cars, and that the blinds, screens and glass windows can slide up and down to open or close. For example, a foreign customer in Bangladesh requires that three layers of windows be installed on the windows of railway passenger cars with a side wall thickness of only 90mm, namely blinds, screens and glass windows. The blinds can block the outside view to ensure the safety of passengers in the car; the screens can filter out impurities, block mosquitoes and have ventilation functions; the glass windows can realize lighting, windproof, rainproof and other functions. How to install integrated blinds, screens and glass windows on the side wall of the window installation, and make them slide up and down, is a technical problem that needs to be solved in this field.
