Abstract

A housing includes a main housing part with an opening as well as a covering device for the opening. The covering device has a first cover part, which at least substantially covers the opening and a second cover part which is separate from the first cover part, bears at least in certain regions against the first cover part and has at least one clearance or aperture in the region of the opening. The second cover part is fastened or supported at the main housing part, in particular in the region of a periphery of the main housing part that extends or runs around the opening. The weight of the covering device is therefore low and yet a high level of stability and sealing in relation to fluids is provided.

First claim

The invention claimed is:

1. A housing, comprising:
a main housing part having an opening;
a covering device for said opening, said covering device having a first cover part at least substantially covering said opening and a second cover part bearing at least regionally on said first cover part, said first cover part covering said opening in a fluid-tight manner;
said second cover part having at least one clearance in a vicinity of said opening; and
said second cover part being fastened to or supported on said main housing part;
wherein said opening has a periphery, and said second cover part:
covers said periphery of said opening as a frame,
projects at least partially beyond said first cover part,
extends in at least one of a bent or angled manner around said first cover part and a part of said main housing part and is fastened to said main housing part.

2. The housing according to claim 1 , wherein said main housing part has a periphery extending around said opening, and said second cover part is separate from said first cover part and is fastened to or supported on said main housing part in a vicinity of said periphery of said main housing part.

3. The housing according to claim 2 , which further comprises a seal extending around said opening between said first cover part and said periphery of said main housing part.

4. The housing according to claim 3 , wherein said first cover part has a main surface and a peripheral region, said peripheral region has an encircling rib, and said encircling rib rises from said main surface of said first cover part.

5. The housing according to claim 4 , wherein said first cover part has a periphery with an angled portion forming said encircling rib.

6. The housing according to claim 4 , which further comprises a seal or sealing compound into which said encircling rib projects, in a direction toward said main housing part.

7. The housing according to claim 6 , wherein at least one of said main housing part or said first cover part has a groove in which said seal or sealing compound extends and into which said encircling rib projects.

8. The housing according to claim 1 , which further comprises:
an interior of the housing;
said first cover part having an outer side facing away from said interior of the housing; and
said second cover part being disposed on said outer side of said first cover part.

9. The housing according to claim 1 , which further comprises:
an interior of the housing;
said first cover part having an inner side facing said interior of the housing; and
said second cover part being disposed on said inner side of said first cover part.

10. The housing according to claim 1 , wherein:
said first cover part has an inner side and an outer side;
said opening has a periphery; and
said second cover part extends in a vicinity of said periphery of said opening as a frame on said inner side or said outer side of said first cover part.

11. The housing according to claim 1 , wherein said covering device has a periphery, and said second cover part has at least one crosspiece interconnecting two different points on said periphery of said covering device.

12. The housing according to claim 11 , wherein said two different points are located diametrically opposite one another.

13. The housing according to claim 11 , wherein said at least one crosspiece extends in a straight line.

14. The housing according to claim 1 , wherein said first and second cover parts are formed of the same material.

15. The housing according to claim 1 , wherein said first and second cover parts have the same material thickness.

16. An electronic control unit for a motor vehicle, comprising a housing according to claim 1 .
