Rail transit vehicle emergency escape windows and rail transit vehicles

Abstract

The invention relates to an emergency escape window for a rail transit vehicle, and the window comprises a window frame, a casement, and an actuation mechanism which is used for locking or opening the casement. The actuation mechanism comprises a four-rod structure which is formed by the sequential connection of an action block, a first connecting rod, a handle, and a second connecting rod. The casement is locked in the window frame through a dead point of the four-rod structure, and can be unlocked through the unlocking of the dead point, thereby opening the window. The invention also provides the rail transit vehicle comprising the above window. The window is locked through the dead point of the four-rod structure, is reliable in locking function, is short in starting transmission link, and is quick in emergency usage. The window is simple in structure, is more convenient in installation and use, and is high in reliability.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to an emergency escape window of a rail transit vehicle and a rail transit vehicle including the emergency escape window. Background technique [0002] In modern society, rail transit is increasingly becoming the means of transportation most closely related to people's lives. People's requirements for the safety of rail transit vehicles are also getting higher and higher. At present, the windows of rail transit vehicles are of closed structure. When critical situations such as fire occur, passengers cannot escape in time and cause heavy casualties. [0003] When a dangerous situation occurs, there is a relatively large potential safety hazard in the window opening device of rail transit vehicles. Vehicles generally use safety hammers to break windows. The safety hammer is easy to lose, and the window breaking efficiency is not high, and the effect is not ideal. [...

AI Technical Summary

Problems solved by technology

At present, the windows of rail transit vehicles are closed structures. In the event of a critical situation such as a fire, passengers cannot escape in time and cause heavy casualties.

[0003] In the event of a dangerous situation, the window opening device of the rail transit vehicle has a relatively large safety hazard

Safety hammers are commonly used on vehicles to break windows. The safety hammer is easy to lose, and the window breaking efficiency is not high, and the effect is not ideal.
