Abstract

A device for contactless transmission of data and energy and for angle measurement, including a first disk-shaped unit and a second disk-shaped unit, which move in relation to one another around a shared rotational axis and are opposite to one another axially spaced apart with respect to the rotational axis. The first disk-shaped unit including a first annular disk-shaped recess, and the second disk-shaped unit including a first annular disk-shaped recess, which is opposite to the first annular disk-shaped recess of the first disk-shaped unit radially spaced apart with respect to the rotational axis. The first disk-shaped unit includes at least one second annular disk-shaped unit situated concentrically to the first annular disk-shaped recess of the first disk-shaped unit, and the second disk-shaped unit includes at least one second annular disk-shaped recess situated concentrically to the first annular disk-shaped recess of the second disk-shaped unit.

First claim

What is claimed is:

1. A device for contactless transmission of data and of energy and for angle measurement, comprising:
a first disk-shaped unit and a second disk-shaped unit, which move in relation to one another around a shared rotational axis and are opposite to one another axially spaced apart with respect to the rotational axis;
wherein the first disk-shaped unit includes a first annular disk-shaped recess,
wherein the second disk-shaped unit including a first annular disk-shaped recess, which is opposite to the first annular disk-shaped recess of the first disk-shaped unit radially spaced apart with respect to the rotational axis,
wherein the first disk-shaped unit includes at least one second annular disk-shaped unit situated concentrically to the first annular disk-shaped recess of the first disk-shaped unit,
wherein the second disk-shaped unit includes at least one second annular disk-shaped recess situated concentrically to the first annular disk-shaped recess of the second disk-shaped unit,
wherein at least one component for energy transmission, and/or at least one component for data transmission, and/or at least one component for angle measurement is situated in each case in the first and at least one second annular disk-shaped recess of the first disk-shaped unit,
wherein the at least one component for data transmission of the first disk-shaped unit is situated in the annular disk-shaped recess of the first disk-shaped unit which has a smallest radial distance to the rotational axis, and
wherein the at least one component for angle measurement of the first disk-shaped unit is situated in the annular disk-shaped recess of the first disk-shaped unit which has a greatest radial distance to the rotational axis.

2. The device as recited in claim 1 , wherein the at least one second annular disk-shaped recess of the first disk-shaped unit is opposite to one of the at least one second annular disk-shaped recesses of the second disk-shaped unit radially spaced apart with respect to the rotational axis.

3. The device as recited in claim 1 , wherein the first disk-shaped unit is constructed in one piece, and/or the second disk-shaped unit is constructed in one piece.

4. The device as recited in claim 1 , wherein the first disk-shaped unit and/or the second disk-shaped unit is made up of a magnetic material.

5. The device as recited in claim 1 , the first disk-shaped unit and/or the second disk-shaped unit is made up of ferrite.

6. The device as recited in claim 1 , wherein the first disk-shaped unit and the second disk-shaped unit are situated spaced apart in relation to one another in such a way that an air gap is located between the first disk-shaped unit and the second disk-shaped unit.

7. The device as recited in claim 1 , wherein at least one component for energy transmission, and/or at least one component for data transmission, and/or at least one component for angle measurement is situated in each case in the first and at least one second annular disk-shaped recess of the second disk-shaped unit.

8. The device as recited in claim 7 , wherein: (i) the at least one component for energy transmission of the first disk-shaped unit is opposite to the at least one component for energy transmission of the second disk-shaped unit radially spaced apart with respect to the rotational axis, and/or (ii) the at least one component for data transmission of the first disk-shaped unit is opposite to the at least one component for data transmission of the second disk-shaped unit radially spaced apart with respect to the rotational axis, and/or (iii) the at least one component for angle measurement of the first disk-shaped unit is opposite to the at least one component for angle measurement of the second disk-shaped unit radially spaced apart with respect to the rotational axis.

9. The device as recited in claim 1 , wherein the at least one component for energy transmission of the first disk-shaped unit is situated in the annular disk-shaped recess of the first disk-shaped unit, which has an average radial distance to the rotational axis, lying between the smallest radial distance to the rotational axis and the greatest radial distance to the rotational axis.

10. The device as recited in claim 1 , wherein the first disk-shaped unit includes a recess along the rotational axis, and/or the second disk-shaped unit includes a recess along the rotational axis, wherein an electric motor configured to generate a relative movement of the first disk-shaped unit and the second disk-shaped unit in relation to one another is situated in the recess of the first disk-shaped unit and/or in the recess of the second disk-shaped unit.

11. A LIDAR sensor including a device for contactless transmission of data and energy and for angle measurement, comprising:
a first disk-shaped unit; and
a second disk-shaped unit, wherein the first disk-shaped unit and the second disk-shaped unit move in relation to one another around a shared rotational axis and are opposite to one another axially spaced apart with respect to the rotational axis;
wherein the first disk-shaped unit includes a first annular disk-shaped recess,
wherein the second disk-shaped unit including a first annular disk-shaped recess, which is opposite to the first annular disk-shaped recess of the first disk-shaped unit radially spaced apart with respect to the rotational axis,
wherein the first disk-shaped unit includes at least one second annular disk-shaped unit situated concentrically to the first annular disk-shaped recess of the first disk-shaped unit, and
wherein the second disk-shaped unit includes at least one second annular disk-shaped recess situated concentrically to the first annular disk-shaped recess of the second disk-shaped unit,
wherein at least one component for energy transmission, and/or at least one component for data transmission, and/or at least one component for angle measurement is situated in each case in the first and at least one second annular disk-shaped recess of the first disk-shaped unit,
wherein the at least one component for data transmission of the first disk-shaped unit is situated in the annular disk-shaped recess of the first disk-shaped unit which has a smallest radial distance to the rotational axis, and
wherein the at least one component for angle measurement of the first disk-shaped unit is situated in the annular disk-shaped recess of the first disk-shaped unit which has a greatest radial distance to the rotational axis.
