Double-opening automatic door system for rail vehicle

Abstract

The invention relates to a double-opening automatic door system for a rail vehicle. The double-opening automatic door system comprises a first door, a second door and a bearing driving mechanism, the first door and the second door are opened oppositely, the bearing driving mechanism is arranged above the first door and the second door and connected with a vehicle body to drive the same to move relatively, each of the first body and the second body is formed by assembling multiple sections, a pull rod mechanism is arranged inside each of part of the sections in the first door and the second door, two ends of each pull rod mechanism are connected with different sections respectively, and each two adjacent sections are enabled to be in relatively-fixed detachable connection. A door structure is formed by assembling multiple detachable sections, and the pull rod mechanisms are adopted for connection, so that the double-opening automatic door system has the advantage of convenience in demounting; part of structure of the doors can be replaced alone when being damaged, so that manufacturing cost and maintenance cost of the doors are lowered.

Description

technical field [0001] The invention relates to an automatic door, in particular to a double-opening automatic door system for rail vehicles. Background technique [0002] High-speed trains generally adopt an automatic door system. The principle is that the door panel is supported on the guide rail by a bracket, and the door body is driven by a driving device to slide on the guide rail. Most of the existing train door structures are non-metallic and metal composite materials, rather than mechanical structures. , so there is no possibility of disassembly and maintenance. Once part of the door structure is damaged, only the whole door structure can be replaced. Therefore, the maintenance process is cumbersome. During maintenance, the entire door body needs to be removed and reinstalled. Not only the maintenance time is long, And the maintenance cost is also high. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The object of t...
