Abstract
The invention relates to an inductive pick-up to be mounted on an electric vehicle, operated with electric energy produced by the inductive pick-up by magnetic induction. The inductive pick-up includes a pick-up portion, a mounting portion, and an actuator. The invention also relates to an electric land vehicle including an inductive pick-up mounted at the bottom of the vehicle. The invention also relates to a method of operating an electric vehicle having an inductive pick-up portion.
Claims15
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 an 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 from the pick-up portion to the mounting portion in a vertical direction can be varied by the actuator,
- wherein
- the actuator comprises a prolongable section which can be prolonged and shortened by operating the actuator and which extends from a first bearing attached to the mounting portion to a second bearing attached to the pick-up portion,
- 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 from the pick-up portion to 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.
An electric land vehicle an inductive pick-up, wherein the inductive pick-up is mounted at the bottom of the vehicle, so that a pick-up portion can be moved by an actuator between a lower position, in which a distance between the pick-up portion and a mounting portion is larger, and a higher position, in which the distance between the pick-up portion and the mounting portion is smaller.
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 an 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 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 actuator,
- by prolonging or shortening the prolongable section the distance from the pick-up portion to the mounting portion is varied.
