Abstract

An adjustable self-resetting door mechanism for an outer end door of a railway vehicle comprises an automatic locking door lock, a door carrying frame, a door mechanism bottom plate, a door opening keeping device, an unlocking device, an automatic resetting device and an air cylinder buffering device. The upper side of the left end of the door mechanism bottom plate is connected with the door opening keeping device, the lower side of the right end of the door mechanism bottom plate is connected with the door lock, and the door carrying frame is connected to the lower side of the door mechanismbottom plate in a sliding manner. According to the adjustable self-resetting door mechanism, the door opening keeping device, the unlocking device, the automatic reset device and the air cylinder buffering device are designed on the door mechanism of the outer end door, a door plate can be automatically kept unclosed after the vehicle door is opened, a door closing handle is operated, outer end door design required by the American standard can be met, and under the emergency evacuation condition, the door opening keeping function can ensure that the net passing width of the vehicle door is stable; the door closing force is adjustable, and the use requirements of American ergonomics on 5% women can be met; and the automatic reset function can avoid the risk that under the condition of misoperation, the vehicle door is not locked, and the vehicle door is opened in the vehicle operation process.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle door systems, and in particular relates to an adjustable self-resetting door mechanism for an outer end door of a rail vehicle. Background technique [0002] The outer end door of the rail vehicle is located at the end of the carriage, which plays the role of isolating two adjacent carriages and serves as a passage for the crew and passengers to and from each carriage. [0003] At present, most subways, trams, intercity and high-speed trains at home and abroad use a through-channel structure to connect two adjacent carriages. Most subways and trams do not have outer doors between adjacent carriages. Intercity and high-speed train carriages Each room has a manual or electric outer door. [0004] For some subway vehicles in the United States, in order to realize the rapid decompilation function of the vehicles, there is no through passage between the carriages, and an outer door is installed a...

Problems solved by technology

Existing intercity and high-speed train outer end doors are divided into two types: electric and manual. The function of the electric outer end door is to play the role of compartment partition, allowing passengers to move between cars. It is not suitable for some subways in the United States Vehicle requirements; the manual outer door does not have the function of door opening holding and automatic reset.
