Abstract

The invention discloses a hidden sealed door for a railway vehicle. The hidden sealed door comprises a driving mechanism, a bearing mechanism, door leaves, a sealing frame and a doorsill, wherein the driving mechanism comprises a lead screw nut mechanism; the bearing mechanism comprises bearing trolleys, and two upper guide rails and two lower guide wheels which are used for performing guidance for the translation, sliding and plugging movement of the door leaves; nuts of the lead screw nut mechanism are connected with each bearing trolley through a hinge mechanism; and when opened, the doorsill is located within the wall body of the railway vehicle. According to the hidden sealing door for the railway vehicle, provided by the invention, jiggle sliding and plugging movement is additionally arranged based on the original hidden translation door; adhesive tape sealing is adopted to replace the brush sealing structure, so that the sealing effect of the railway vehicle door system is improved; meanwhile, electrically controlled door is used, and the acoustic and thermal insulation property is good, so that the comfort requirement of a passenger can be satisfied; and the structure is simple, the sliding and plugging movement can be achieved without an air supply, and the time required for shutting the door is short.

Description

technical field [0001] The invention relates to a rail vehicle, in particular to a built-in airtight door of the rail vehicle. Background technique [0002] In terms of rail vehicle door system, with the rapid development of rail vehicle industry, especially the continuous increase of vehicle speed, new requirements are put forward for the matching door system in terms of reliability, safety, practicability and sealing. . The existing door systems are mainly external sliding doors, built-in sliding doors and sliding doors, but the left and right sides of the external hanging sliding doors and built-in sliding doors are sealed with rubber strips, and only brushes can be used on the upper and lower parts Blocking dust, can not play a sealing effect. In the existing built-in swing door, when the door is closed in place, the pressure lock squeezes and seals the door leaf to the outside of the vehicle. This structure needs to start and control the pressure lock. The mechanism i...
