The pantograph head assembly comprises a bottom frame, a top frame and a first elastic component, the bottom frame is used for being connected with an upper arm of the pantograph, the top frame comprises a carbon sliding plate, two inclined guide plates and two connecting frames, and the two connecting frames are fixed to the two ends of the carbon sliding plate respectively; the two connecting frames are movably connected to the corresponding inclined guide plates, the connecting frames and the inclined guide plates can move relatively in the width direction of the carbon sliding plate, the inclined guide plates are connected to the bottom frame, first elastic components are arranged between the connecting frames and the inclined guide plates, and second elastic components are arranged between the connecting frames and the inclined guide plates. And in the relative movement process of the connecting frame and the inclined guide plate, the first elastic component deforms. The carbon slide plate of the pantograph head assembly can slightly move in the advancing direction when being subjected to external force in the vehicle advancing direction, the first elastic component can deform, the buffering effect is achieved, and therefore the pantograph head assembly can be protected, damage to the pantograph head assembly under the external force is relieved, and the service life of the pantograph head assembly is prolonged.
本发明公开一种弓头组件及受电弓,弓头组件包括:底架、顶架和第一弹性部件,底架用于连接受电弓的上臂,顶架包括碳滑板、两个倾斜导向板和两个连接架,两个所述连接架分别固定于碳滑板的两端,两个所述连接架均可活动地连接于相应的倾斜导向板,所述连接架和所述倾斜导向板能沿碳滑板的宽度方向相对运动,所述倾斜导向板连接于所述底架,第一弹性部件设置于所述连接架和所述倾斜导向板之间,在所述连接架和所述倾斜导向板相对运动的过程中,所述第一弹性部件发生形变。本申请的弓头组件的碳滑板在车辆行进方向上受到外力时会沿行进方向轻微移动,第一弹性部件会发生形变,起到缓冲的作用,从而可保护弓头组件,减轻了弓头组件在外力作用下的损伤,延长了弓头组件的使用寿命。
