Built-in plug door device for rail vehicle

Abstract

The invention discloses a built-in plug door device for a rail vehicle. The device comprises a control mechanism, a driving mechanism, a bearing mechanism, a compaction mechanism, a guide chute and a door leaf; the bearing mechanism comprises a guide post, two sleeves, a connecting rod, a sliding block and a guide wheel; and the control mechanism is respectively connected with the driving mechanism and the compaction mechanism. The advantages of an outward swing plug door and a built-in side sliding door are combined in the built-in plug door device, and the problem of smooth appearance of the built-in side sliding door is solved by plug movement; the outer side of the body is smoother, the influence of high-speed running pressure wave on the door leaf is reduced, and high-speed running noise is reduced; the body is 140 millimeters wider than the body using the outward swing plug door; and when the plug process of the door leaf is finished, the door leaf is compacted on the body, and the possibility that the door leaf drops outwards is totally limited, so safety and sealing reliability are improved.

Description

technical field [0001] The invention relates to a door device used for rail vehicles, in particular to a built-in sliding door device for rail vehicles. Background technique [0002] At present, the entrance automatic door systems of high-speed trains, main line trains and urban rail trains at home and abroad are basically divided into three categories: swing-out sliding doors, built-in side sliding doors and external sliding doors. Such as figure 1 As shown, the swing-out sliding door mainly drives the opening and closing of the door leaf 1' through the driving device. The key features are: when the door is closed, the outside of the door leaf 1' is flush with the outside of the vehicle, and when the door is opened, it faces the outside of the car body 2' ( Y direction) swing out, usually about 70mm, 3' in the figure is the motion track of the door leaf 1'. [0003] The following problems exist in the use of the swing-out sliding door: (1) The 2' width of the car body is ...

AI Technical Summary

Problems solved by technology

[0003] The following problems exist in the use of the swing-out sliding door: (1) The 2' width of the car body is reduced: usually, the automatic door system is symmetrically arranged on both sides of the railway vehicle, so the space on both sides is about 140mm due to the swinging out of the door

This solution meets the 2' wide car body and safety requirements, but there are still the following problems: (1) high-speed operation, especially when the operating speed is greater than 250km / h, the aerodynamic characteristics are poor, the running resistance is large, and the energy consumption is high; (2) The appearance is not smooth, and the existence of height difference makes the aerodynamic noise larger during operation; (3) There is a certain height between the door leaf 1' and the outer wall, which affects the appearance of the vehicle; (4) Vehicles with built-in side sliding doors Not suitable for mechanized operations when cleaning in the door area

Since the door leaf protrudes outside the car body, there are the following problems: (1) the aerodynamic characteristics of the vehicle are poor when running, and the noise is loud at high speed; (2) the protruding door leaf occupies the gap between the vehicle and the platform, making the width of the car body Affected, the hull cannot be too wide
