Robotic arm for conductive charging of an electrically powered vehicle and method for conductive charging

摘要

The invention relates to a robot arm (9) for the conductive charging of an electrically operated vehicle, wherein the robot arm (9) has at least two axes, two arm sections (1, 2, 3) of the robot arm (9) are exclusively rotationally movable, the arm sections (1 , 2, 3,) via joints (10) are interconnected and at a distal end of the robot arm (9) a contacting unit (4) is arranged. Furthermore, the invention relates to a robot arm (9) for the conductive charging of an electrically operated vehicle with a base unit (5), a support unit (7) and a lifting unit (6), wherein the support unit (7) with respect to the base unit (5) pure translationally in a plane or translationally in the plane and rotationally about an axis perpendicular to the plane is movable and the support unit (7) with the lifting unit (6) relative to the base unit (5) in a stroke direction perpendicular to the plane is movable. Furthermore, the invention relates to a method for the conductive charging of an electrically operated vehicle, wherein a position of the electrically operated vehicle is determined, based on the position by purely translational or purely rotational movements, a contacting unit (4) of a robot arm (9) on the electrically operated vehicle is contacted and the charging unit (4) is held on the electrically operated vehicle during a charging operation.
