Abstract

The invention discloses a front end opening and closing mechanism and a rail vehicle. The front end opening and closing mechanism comprises a flow guide cover mechanism, a connecting mechanism, a movement mechanism, a guide mechanism and a driving mechanism. One end of the connecting mechanism is connected with the flow guide cover, and the moving mechanism is connected with the other end of the connecting mechanism; the driving mechanism is connected with the movement mechanism, the guide mechanism is arranged corresponding to the fairing mechanism, and the guide mechanism is connected with the connecting mechanism. Under the action of the driving mechanism, the movement mechanism drives the connecting mechanism to slide back and forth along the guide mechanism, so that guide of the opening and closing track of the flow guide cover mechanism is realized. The technical problem that in the prior art, the movement track of a front end opening and closing mechanism cannot be changed is solved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a front-end opening and closing mechanism and a rail vehicle. Background technique [0002] As one of the important components of the rail train, the front-end opening and closing mechanism is mainly used to control the opening and closing of the front-end shroud through the opening and closing mechanism. When the shroud is opened, the rail train can perform coupler reconnection and emergency rescue. , Equipment maintenance and other operations. When the shroud is closed, the rail train can have a streamlined shape during high-speed operation, reducing running resistance and improving safety and stability. [0003] Because the front end of the train is often equipped with couplers, anti-climbers or other devices, the space is relatively compact, and the opening and closing mechanism must avoid other internal components such as anti-climbers during the opening a...
