Embodiment Construction

[0011] The "black ditch" door mechanism of this rail transit vehicle as shown in the figure is composed of an automatic door 2, a carriage floor 6, etc., and is characterized in that a piece with the same width as the entrance and exit of the automatic door 2 is designed under the inner floor 2 of the carriage. , and through the protruding plug-in shaft 5 on one side of the bottom of the automatic door 2, the auxiliary pedal 3 is connected to the linkage.

[0012] The auxiliary pedal 3 is provided with a group of symmetrical arc-shaped slide grooves 4 for the left and right automatic doors to slide.

[0013] The auxiliary pedal 3 is in an inverted "T" shape, and its tail is placed in the chute 9 formed by two positioning groove plates 8 arranged on the left and right.

[0014] The working principle of the "black ditch" door mechanism of this rail transit vehicle is:

[0015] Owing to inserting the plug-in shaft 5 added on one side of the bottom of the automatic door into the ...

Abstract

The invention introduces a door structure of rail transit vehicle, comprising automatic door and carriage bottom plate so on, characterized in that an assistant footplate with corresponding width of in-out port of automatic door and linked by convex inserting shaft at one side of the bottom of automatic door is designed under the carriage bottom plate; a group of symmetrical arc sliding grooves for left and right automatic doors sliding is set on the assistant footplate; the assistant footplate is reverse T-shape and the tail is set in the sliding groove constituted by two locating groove plates set in left and right. The implement of door structure can eliminate the black groove formed by vehicle body and platform when vehicle stops and passengers get up and down. It is very beneficial for guaranteeing the safety of up-down passenger and improving safe running of rail vehicle.

Description

technical field [0001] The invention relates to a door mechanism of a rail transit vehicle, which belongs to the design method or device of a rail vehicle door. Background technique [0002] With the increasing development of modern urban rail transportation network, subway, light rail and maglev train have become important means of transportation for fast and efficient urban people. However, due to design limitations, the gap between the running vehicle and the platform forms a "black ditch" at the door. When getting on and off the bus, passengers must carefully step up and down the ladder, or cross this visible "black ditch". Ditch", this "black ditch" is a hidden danger that threatens the personal safety of passengers. How to eliminate the "black ditch" formed between the rail vehicle door and the platform is not only the need for technical improvement of the rail transit industry, but also the need to ensure the personal safety of the majority of passengers.
