Abstract

A mobile inductive charging station for vehicles has an overlay, a primary coil connected to the overlay, and at least one recess on an upper side of the overlay. The recess is equipped with inner side faces and is adapted to receive at least one tire contact area of a vehicle tire. The overlay has a flat underside opposed to the upper side.

Claims

1. A mobile inductive charging station for a vehicle, the inductive charging station comprising:

an overlay having an upper side and a flat underside opposite said upper side;

a primary coil connected to said overlay; and

said overlay having at least one recess formed on said upper side of said overlay, said at least one recess having an inner side face and being configured to receive at least one tire contact area of a vehicle tire.

2. The mobile inductive charging station according to claim 1, wherein said at least one recess is one of two recesses each having a respective said inner side face.

4. The mobile inductive charging station according to claim 1, which further comprises an arresting device equipped with a locking member and an actuator, wherein said actuator is connected to said locking member and is configured to move said locking member controllably in front of and/or behind the recess.

5. The mobile inductive charging station according to claim 4, wherein:

said locking member, by virtue of the connection to the actuator, has a direction of movement which is parallel to said upper side;

or

said locking member, by virtue of the connection to the actuator, has a direction of movement which is perpendicular to the upper side.

6. The mobile inductive charging station according to claim 5, wherein the direction of movement of said locking member is defined by a rod which is guided parallel to said upper side.

7. The mobile inductive charging station according to claim 5, wherein the direction of movement of said locking member is defined by a flexible arresting portion of said upper side of the inductive charging station, which can be moved by said actuator perpendicular to said upper side.

8. The mobile inductive charging station according to claim 1, which comprises a foreign body removal device disposed at at least one coil portion of the upper side of the inductive charging station, which is situated above said primary coil.

9. The mobile inductive charging station according to claim 8, wherein said foreign body removal device comprises a plurality of nozzles and a compressed air source connected to said nozzles, wherein said nozzles include apertures on the coil portion of the upper side.

10. The mobile inductive charging station according to claim 5, wherein said foreign body removal device comprises an actuator arrangement, connected to the coil portion, said actuator arrangement defining a variable inclination of the coil portion.

11. The mobile inductive charging station according to claim 5, wherein the coil portion is movable at at least one point and said foreign body removal device comprises a compressed air source and at least one nozzle, which is connected thereto and which is directed in a direction along the coil portion.

12. The mobile inductive charging station according to claim 1, which further comprises at least one drive channel let into said upper side and leading to said recess.

13. The mobile inductive charging station according to claim 1, which further comprises a head part and a plug-and-socket connection affixing said head part to said overlay, and wherein a control device and/or a power output stage connected to said primary coil are provided in said head part, said head part having a rigid housing in which at least one or both of said control device or said power output stage are accommodated.

3. The mobile inductive charging station according to claim hich further comprises an arresting device, said arresting device comprising a locking face that corresponds to said at least one inner side face, and an actuator, which is connected to said locking face and is configured to move said locking face controllably towards and away from a center of said at least one recess.
