Description

Technical Field

[0001] The utility model relates to an emergency evacuation door for a rail transit vehicle, in particular to a multifunctional large-opening evacuation door leaf. Background Art

[0002] Urban rail transit vehicles generally use end evacuation to evacuate passengers, which requires the installation of emergency evacuation doors at the end of the vehicle. Traditional emergency evacuation doors are usually set at the front of the driver's cab. Generally, the clear width of the emergency evacuation door is about 460mm, which divides the front window glass of the driver's cab equipped with an evacuation door into three or two areas, affecting the transparency and vision in the driver's cab, and also has a certain impact on the appearance, and is not conducive to the rapid evacuation of passengers in an emergency. At the same time, since the front window glass is divided into multiple parts, multiple wipers are required.

[0003] Based on the defects of the existing urban rail evacuation door system, CN201611177849 discloses a large-opening evacuation door for rail vehicles, which improves the driver's cab field of vision, but also has the following problems:

[0004] 1) When the door leaf is fully opened at the head of the rail train, there is no installation space for some of the necessary equipment for the train functions, such as running lights and rain sensors, which have no location to be installed or cannot meet the functional requirements;

[0005] 2) The sunshade is a necessary equipment in the driver's cab. If the above plan is followed and the sunshade is installed close to the glass, the tracks on both sides of the sunshade will block the inspection opening of the evacuation door. Therefore, the sunshade can only be installed away from the evacuation door (400mm), encroaching on the space inside the driver's cab.

[0006] 3) Because some components are integrated in the door leaf, the wiring harness connecting the components and the vehicle is laid on the top plate outside the door leaf. The wiring harness is visible from the gap between the door leaf and the interior decoration inside the vehicle, seriously affecting the appearance.

[0007] 4) The back of some undecorated equipment in the driver's cab can be seen through the large glass door from outside the vehicle, which seriously affects the appearance. Utility Model Content
