Abstract

An imaging system ( 1 ) for a motor vehicle, having a camera housing ( 2 ) and at least one camera module ( 3 ) to be mounted to the camera housing ( 2 ). The camera housing ( 2 ) is provided with an arrangement of at least two first abutments ( 4,5,6 ) with a defined geometry and orientation at which the camera module ( 2 ) abuts, wherein the camera module ( 3 ) is spring loaded against the first abutments ( 4,5,6 ) with at least one spring element ( 7 ).

First claim

The invention claimed is:

1. An imaging system for a motor vehicle, comprising,
a camera housing forming an opening,
a camera module mounted to the camera housing and extending through the opening wherein,
the camera housing is provided with at least two first abutments with a defined geometry and orientation at which the camera module abuts, the at least two first abutments are arranged in a rim section of the camera housing adjacent to the opening,
the camera module is spring loaded against the at least two first abutments with at least one spring element, and
the at least one spring element is provided in the form of a first ring, overlapping the rim section the camera housing is provided with a stopper for limiting the rotation movement of the first ring.

2. An imaging system as claimed in claim 1 further comprising, the camera module is provided with at least one first projection directed into a radial direction.

3. An imaging system as claimed in claim 2 further comprising,
the camera module engages with the at least one first projection into a first recess of the camera housing or of a part fixed at the camera housing, wherein
the first recess is open in an axial direction of the camera module and enables a relative movement of the camera module in the axial direction and blocks a relative movement of the camera module in a circumferential direction at least in one step of an assembly process.

4. An imaging system as claimed in claim 2 further comprising, the camera housing is provided with at least one second projection with at least one second abutment.

5. An imaging system as claimed in claim 4 further comprising,
the at least one first projection of the camera module is arranged between the at least one first and the at least one second abutment, wherein
the at least one spring element is arranged between the at least one second abutment of the at least one second projection and the at least one first projection pressing the camera module towards the at least one first abutment.

6. An imaging system as claimed in claim 4 further comprising at least two of the second projections are provided at the camera housing, and the at least one second abutment is designed as a second ring which is attached at each of the at least one second projections.

7. An imaging system as claimed in claim 6 further comprising, the first ring and the second ring are formed of a corresponding shape.

8. An imaging system for a motor vehicle comprising,
a camera housing forming an opening,
a camera module mounted to the camera housing, the camera module is provided with at least one first projection directed in a radial direction, the camera module extending through the camera housing opening,
the camera housing is provided with at least two first abutments with a defined geometry and orientation at which the camera module abuts, the at least two first abutments are arranged in a rim section of the camera housing adjacent to the opening,
the camera module is spring loaded against the at least two first abutments with at least one spring element provided in the form of a first ring, overlapping the rim section,
the at least one first projections of the camera module comprises at a side facing to the at least one spring element an oblique surface which forms an angled orientation with respect to a plane defined by the at least two first abutments of the camera housing, and
the at least one spring element is abutting at the oblique surface and is adapted to perform a relative movement versus the at least one first projection with a pressing the camera module against the at least two first abutments.

9. An imaging system as claimed in claim 8 further comprising, the camera housing is provided with a stopper for limiting the rotation movement of the first ring.

10. An imaging system for a motor vehicle comprising,
a camera housing forming an opening,
a camera module mounted to the camera housing, the camera module is provided with at least one first projection directed in a radial direction, the camera module extending through the camera housing opening,
the camera housing is provided with at least two first abutments with a defined geometry and orientation at which the camera module abuts, the at least two first abutments are arranged in a rim section of the camera housing adjacent to the opening,
the camera module is spring loaded against the at least two first abutments with at least one spring element provided in the form of a first ring, overlapping the rim section,
the first ring is arranged rotatable with respect to an axial direction of the camera module to be rotated into an attachment position.

11. An imaging system as claimed in claim 10 further comprising, the camera housing includes a blocking structure which prevents a rotation of the first ring out of the attachment position.

12. An imaging system as claimed in claim 10 further comprising, the first ring forms several arc shaped openings which are arranged concentrically to a rotation axis through which at least one first projection of the camera housing extends.
