Opening and closing mechanism and railway vehicle

Abstract

The invention provides an opening and closing mechanism and a railway vehicle. The opening and closing mechanism comprises a first side opening and closing assembly. The first side opening and closingassembly comprises a supporting base body, a rotating arm and a driving arm; the rotating arm is rotationally connected with the supporting base body; the driving arm is rotationally connected with the supporting base body; the rotation axis, relative to the supporting base body, of the rotating arm and the rotation axis, relative to the supporting base body, of the driving arm are arranged at intervals; and the driving arm is connected with the rotating arm through a motion transmission mechanism, so that the driving arm can rotate to drive the rotating arm to rotate. The opening and closingmechanism can be used for a railway vehicle to control opening and closing of a vehicle fairing. According to the opening and closing mechanism, a motion driving structure of a rotating shaft openingand closing mechanism is improved, the rotation axis, relative to the supporting base body, of the rotating arm and the rotation axis, relative to the supporting base body, of a rotating arm drivingstructure are designed to be of a non-coaxial structure, rotating arm driving action components are separated from the rotating arm, the action space of the rotating arm driving structure is increased, and the problem of motion interference among components in the opening and closing process of the fairing can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of door body opening and closing, and in particular relates to an opening and closing mechanism and a rail vehicle. Background technique [0002] There are mainly two ways of opening and closing the shroud: rotating and opening around a fixed rotating shaft, or opening and moving along a fixed track. The opening and closing mechanism that rotates around a fixed shaft has a simple structure and reliable locking. It is widely used on rail vehicles, but its applicability is poor, and it is affected by the shape of the shroud, the position of the front end of the car and the installation position of other components on the car end. , which cannot be achieved in some cases. The opening and closing mechanism that moves along a fixed trajectory is complicated in action and has many functional components, so it is inconvenient to resist, and it is more difficult to design and manufacture. Its applicability is bette...
