The invention discloses a rail vehicle and a front end opening and closing mechanism thereof, the front end opening and closing mechanism comprises at least one group of driving assemblies, all the driving assemblies can synchronously control opening or closing of a front end hood, and the front end hood comprises an upper hood and a lower hood; each driving assembly comprises an upper supporting rod which is rotatably arranged and fixedly connected with the upper hood, a lower supporting rod which is rotatably arranged and fixedly connected with the lower hood, and a linear driving piece with the movable end in sliding connection with the upper supporting rod and the lower supporting rod. When the linear driving piece extends outwards, the upper supporting rod and the lower supporting rod respectively drive the upper hood and the lower hood to move oppositely, and the front-end hood is opened; when the linear driving piece contracts inwards, the upper supporting rod and the lower supporting rod drive the upper head cover and the lower head cover to move oppositely, and the front end head cover is closed. According to the driving assembly, the front end hood can be controlled to be opened or closed only through one linear driving piece, the number of related parts is small, the result is simple, the occupied space is small, and the space utilization rate of a forecabin can be effectively increased.

    本发明公开了一种轨道车辆及其前端开闭机构,前端开闭机构包括至少一组驱动组件,全部驱动组件能同步控制前端头罩打开或关闭,前端头罩包括上头罩和下头罩,每组驱动组件包括可转动设置并与上头罩相固连的上支杆、可转动设置并与下头罩相固连的下支杆及活动端分别与上支杆和下支杆滑动连接的线性驱动件。当线性驱动件向外伸出时,上支杆和下支杆二者分别带动上头罩和下头罩相背运动,前端头罩打开;当线性驱动件向内收缩时,上支杆和下支杆二者分别带动上头罩和下头罩相向运动,前端头罩关闭。本发明中驱动组件仅需一套线性驱动件便控制前端头罩打开或关闭,涉及的部件数量较少,结果较简单,占用空间较小,能有效提高前舱的空间利用率。
