First Claim
Patent Images
1. An inductive pick-up to be mounted on an electric vehicle which shall be operated with electric energy produced by the inductive pick-up by magnetic induction, wherein:
- the inductive pick-up comprises a pick-up portion comprising at least one electric inductance for receiving a magnetic field and for producing the electric energy,the inductive pick-up comprises a mounting portion to be mounted on the vehicle,the inductive pick-up comprises a linear actuator for actuating movement of the pick-up portion relative to the mounting portion,the mounting portion and the pick-up portion are moveably connected to each other by at least two connecting portions,wherein a distance between the pick-up portion and the mounting portion in a vertical direction can be varied by the linear actuator,whereinthe linear actuator comprises a prolongable section which extends from a first bearing attached to the mounting portion to a second bearing attached to the pick-up portion and which can be prolonged and shortened by operating the linear actuator thereby prolonging or shortening a distance between the first bearing and the second bearing,the prolongable section comprises a first operating state in which the prolongable section is shorter than in a second operating state, so that the distance between the pick-up portion and the mounting portion is smaller in one of the first and second operating states than in the other of the first and the second operating states.

9. A method of operating an electric vehicle, wherein:
-
an inductive pick-up portion, which is moveably connected to a mounting portion that is mounted at a bottom of the electric vehicle, is moved using a linear actuator between a lower position, in which a distance between the pick-up portion and the mounting portion is larger, and a higher position, in which the distance between the pick-up portion and the mounting portion is smaller, movement of the pick-up portion relative to the mounting portion is guided using at least two connecting portions which connect the pick-up portion and the mounting portion, wherein a prolongable section of the linear actuator, which prolongable section extends from a first bearing attached to the mounting portion to a second bearing attached to the pick-up portion, is prolonged or shortened while operating the linear actuator thereby prolonging or shortening a distance between the first bearing and the second bearing, by prolonging or shortening the prolongable section the distance between the pick-up portion to the mounting portion is varied. - View Dependent Claims (10, 11, 12, 13, 14, 15)
