The utility model provides a bow head unit and a charging bow. The pantograph head unit can be connected with a telescopic unit and comprises two electrode connecting rods attached with electrode plates, elastic assemblies correspondingly connected with the two electrode connecting rods and a connecting piece hinged to the two elastic assemblies or the telescopic unit, so that the electrode connecting rods rotate with the connecting piece as the axis. The charging bow comprises the bow head unit. The bow head unit comprises a bow head and a charging bow, two electrode connecting rods pasted with electrode plates, an elastic assembly and a connecting piece are arranged; the two electrode connecting rods can rotate around the connecting piece and can move up and down, the lap joint problem caused when the pantograph is uneven can be solved, the electrode plates are attached to the electrode connecting rods, the structure is simple and reliable, and pressure transmission and adjustment ofthe elastic assemblies on the two sides are facilitated.
