Abstract

A heat protection device for a wheel electronics unit on a rim of a wheel of a vehicle, having a main body with a fastening portion for fastening to the wheel electronics unit, and at least one heat protection portion for thermally insulating the wheel electronics unit in the fastened position.

First claim

What is claimed is:

1. A heat protection device for a wheel electronics unit on a rim of a wheel of a vehicle, said heat protection device comprising:
a main body having (i) an interior space for receiving the wheel electronics unit in a fastened position, the interior space being formed by a lower wall and side walls extending from the lower wall, (ii) a floor surface defined on the lower wall, the floor surface being oriented to face the wheel electronics unit, (iii) a fastening portion on one of the side walls for fastening to the wheel electronics unit in the fastened position, and
at least one heat protection portion for thermally insulating the wheel electronics unit in the fastened position, wherein the heat protection portion comprises a spacer foot that extends from the lower wall to directly contact the rim of the wheel such that a space is formed between the rim of the wheel and the lower wall of the main body.

2. The heat protection device as claimed in claim 1 , wherein the fastening portion is configured to be fastened to the wheel electronics unit by way of either snapping or latching action.

3. The heat protection device as claimed in claim 1 , wherein the heat protection portion further comprises a heat reflection surface defined on a lower surface of the lower wall that faces the rim for reflecting radiant heat from an inner side of the rim.

4. The heat protection device as claimed in claim 1 , wherein the main body has an interlocking portion in a region of the fastening portion for interlocking contact connection to the wheel electronics unit.

5. The heat protection device as claimed in claim 1 , wherein the main body has a guide portion for a guided movement into a position fastened to the wheel electronics unit.

6. The heat protection device as claimed in claim 1 , wherein the heat protection portion has a gap region that forms a defined heat protection gap (HS) between the floor surface of the main body and a lower surface of the wheel electronics unit in the fastened position.

7. The heat protection device as claimed in claim 1 , wherein the heat protection portion has a thermally insulating portion that is integrally formed with the main body.

8. A sub-assembly comprising the wheel electronics unit and the heat protection device of claim 1 .

9. A wheel of a vehicle comprising the heat protection device and the wheel electronics unit of claim 1 , wherein the heat protection device and the wheel electronics unit are mounted to each other in a space defined between the rim and a tire that is mounted to the wheel.

10. A heat protection device for a wheel electronics unit on a rim of a wheel of a vehicle, said heat protection device comprising:
a main body having (i) an interior space for receiving the wheel electronics unit in a fastened position, the interior space being formed by a lower wall and side walls extending from the lower wall, (ii) a floor surface defined on the lower wall, the floor surface being oriented to face the wheel electronics unit, (iii) a fastening portion on one of the side walls for fastening to the wheel electronics unit in the fastened position, and
at least one heat protection portion for thermally insulating the wheel electronics unit in the fastened position, wherein the heat protection portion comprises a gap region that forms a defined heat protection gap (HS) between the floor surface of the main body and the wheel electronics unit in the fastened position.

11. The heat protection device as claimed in claim 10 , wherein the heat protection portion further comprises a heat reflection surface defined on a lower surface of the lower wall that faces the rim for reflecting radiant heat from an inner side of the rim.

12. A wheel of a vehicle comprising the heat protection device and the wheel electronics unit of claim 10 , wherein the heat protection device and the wheel electronics unit are mounted to each other in a space defined between the rim and a tire that is mounted to the wheel.

13. A heat protection device for a wheel electronics unit on a rim of a wheel of a vehicle, said heat protection device comprising:
a main body having (i) an interior space for receiving the wheel electronics unit in a fastened position, the interior space being formed by a lower wall and side walls extending from the lower wall, (ii) a floor surface defined on the lower wall, the floor surface being oriented to face the wheel electronics unit, (iii) a fastening portion on one of the side walls for fastening to the wheel electronics unit in the fastened position, and
at least one heat protection portion for thermally insulating the wheel electronics unit in the fastened position, wherein the heat protection portion comprises a heat reflection surface defined on a lower surface of the lower wall that faces the rim for reflecting radiant heat from an inner side of the rim.

14. A wheel of a vehicle comprising the heat protection device and the wheel electronics unit of claim 13 , wherein the heat protection device and the wheel electronics unit are mounted to each other in a space defined between the rim and a tire that is mounted to the wheel.
