Front-end opening-closing mechanism for rail vehicle and rail vehicle comprising same

Abstract

The invention discloses a front-end opening-closing mechanism for a rail vehicle and the rail vehicle comprising the same. The front end of the rail vehicle is provided with a port. The opening-closing mechanism comprises a head hood, a bracket, a swing arm and a driving assembly; the head hood can be switched between the port opening state and the port closing state; the bracket comprises supporting plates; the swing arm is connected with the head hood and movably connected with the bracket; the driving assembly is connected with the bracket and the swing arm so that the swing arm can be driven to drive the head hood to be switched between the opening state and the closing state; and the swing arm is provided with slide blocks capable of sliding relative to the supporting plates. According to the opening-closing mechanism, the swing arm is driven to move through the driving assembly, the head hood is driven by the swing arm to be switched between the opening state and the closing state, port opening and closing can be achieved through the head hood, and in addition, the front-end opening-closing mechanism has the advantages of being simple in structure, reasonable in space layout,good in stability and the like.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to a front end opening and closing mechanism for a rail vehicle and a rail vehicle having the same. Background technique [0002] The front end of the rail vehicle is generally provided with an opening and closing mechanism, and the opening and closing mechanism has two hoods that can be opened and closed. The opening and closing mechanism in the related art is provided with racks and space four-linkages, driven by a cylinder, and driven by the space four-linkages to realize the opening and closing action of the hood. [0003] However, the above-mentioned opening and closing mechanism has complex structure, high requirements for assembly and adjustment, heavy weight, poor spatial layout, poor transmission effect, poor stability, and very inconvenient operation. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in th...
