Abstract

An arrangement is provided for at least one induction coil for inductively charging an energy accumulator on an underbody of a motor vehicle. The induction coil is covered in the vertical direction of the vehicle, towards the base, at least partially by at least one cover element.

Claims

1. A vehicle underbody arrangement, comprising:

an induction coil configured to inductively charge an energy accumulator, the induction coil being arranged on an underbody of a motor vehicle;

a covering element configured to at least partially cover the induction coil on a downward side in a vertical direction of the motor vehicle; and

an underbody protection element adjoining the induction coil, the underbody protection element being configured to protect at least one component other than the induction coil of the motor vehicle,

wherein at least a portion of the induction coil is disposed between the underbody protection element and the covering element.

2. The arrangement according to claim 1, wherein

the underbody protection element at least partially bounds a receiving region in which the induction coil is at least partially accommodated.

3. The arrangement according to claim 2, wherein the covering element is arranged on the underbody protection element.

4. The arrangement according to claim 3, wherein the receiving region is at least partially covered downward in the vertical direction of the motor vehicle by the covering element.

5. The arrangement according to claim 2, wherein the receiving region is at least partially covered downward in the vertical direction of the motor vehicle by the covering element.

7. The arrangement according to claim 4, wherein the underbody protection element has at least one field-guiding region with respective field-guiding elements that intensify and orient a magnetic field during inductive charging.

10. The arrangement according to claim 7, further comprising:

runners arranged on opposite sides of the underbody protection element in a transverse direction of the motor vehicle, the runners being configured to project downward beyond the underbody protection element in the vertical direction of the vehicle.

12. The arrangement according to claim 1, wherein the covering element is accommodated by a frame that surrounds the covering element at least in regions.

6. A vehicle underbody arrangement, comprising:

an induction coil configured to inductively charge an energy accumulator, the induction coil being arranged on an underbody of a motor vehicle;

a covering element configured to at least partially cover the induction coil on a downward side in a vertical direction of the motor vehicle; and

an underbody protection element adjoining the induction coil, the underbody protection element being configured to protect at least one component of the motor vehicle, wherein

the underbody protection element at least partially bounds a receiving region in which the induction coil is at least partially accommodated and

the underbody protection element has at least one field-guiding region with respective field-guiding elements that intensify and orient a magnetic field during inductive charging.

8. The arrangement according to claim 6, wherein the field-guiding elements comprise ferrites.

9. A vehicle underbody arrangement, comprising:

an induction coil configured to inductively charge an energy accumulator, the induction coil being arranged on an underbody of a motor vehicle;

a covering element configured to at least partially cover the induction coil on a downward side in a vertical direction of the motor vehicle;

an underbody protection element adjoining the induction coil, the underbody protection element being configured to protect at least one component of the motor vehicle, wherein the underbody protection element at least partially bounds a receiving region in which the induction coil is at least partially accommodated; and

runners arranged on opposite sides of the underbody protection element in a transverse direction of the motor vehicle, the runners being configured to project downward beyond the underbody protection element in the vertical direction of the vehicle.

11. The arrangement according to claim 9, wherein the runners extend along the opposite sides of the underbody protection element in a longitudinal direction of the vehicle.
