The pantograph is used for solving the problem that in the prior art, a pantograph occupies a large space.
Description
technical field [0001] The invention relates to the technical field of electric vehicle power devices, in particular to a bow head driving device, a pantograph and a charging bow. Background technique [0002] Charging bows and pantographs generally include a bow head and a bow head driving device that drives the bow head to move. The bow head driving device includes an underframe. It is arranged on the upper end of the swing rod, and can also be arranged on the swing rod through the transmission rod. One end of the linear drive mechanism is hinged on the base frame, and the other end is hinged on the swing rod, and the bow head can be lifted up and down through the driving action of the linear drive mechanism. For example, a pantograph device for a wire truck as described in the invention patent application document of application publication number CN104540705A, the pantograph device includes a hydraulic cylinder (that is, a linear drive mechanism), and one end of the hyd...
