Imaging system for a motor vehicle
An imaging system for a motor vehicle, including a camera housing part ( 10 ) and at least one camera module ( 1 ) mounted at an attachment wall ( 12 ) of the camera housing part ( 10 ). The camera module ( 1 ) has a radially outwardly directed flange ( 5 ) with several radially outwardly directed protrusions ( 4 ), and a closed retainer ring ( 8 ). The protrusions ( 4 ) and/or the retainer ring ( 8 ) are elastically deformable, and the retainer ring ( 8 ) is attached by pushing it over the protrusions ( 4 ) under elastic deformation of the retainer ring ( 8 ) and/or the protrusions ( 4 ) to an attachment position. The camera module ( 1 ) is attached at the attachment wall ( 12 ) by clamping the attachment wall ( 12 ) between the retainer ring ( 8 ) and the flange ( 5 ) of the camera module ( 1 ).
1. An imaging system for a motor vehicle, comprising
a camera housing part and at least one camera module to be mounted at an attachment wall of the camera housing part,
the camera module is provided with a radially outwardly directed flange and with a plurality of radially outwardly directed protrusions, and
a closed retainer ring is provided, wherein
the protrusions or the retainer ring is elastically deformable, and
the retainer ring is attached by pushing it over the protrusions under elastic deformation of the retainer ring or the protrusions to an attachment position,
the camera module is attached at the attachment wall by clamping the attachment wall between the retainer ring and the flange of the camera module when the retainer ring is in the attachment position.
2. An imaging system according to claim 1 wherein, the protrusions comprise a conical shape with an increasing thickness in the direction to the flange.
3. An imaging system according to claim 1 further comprising, the flange is provided with three centering surfaces arranged at the side facing towards the attachment wall.
4. An imaging system according to claim 3 wherein, the centering surfaces comprise a conical, a spherical or a flat shape.
5. An imaging system according to claim 3 further comprising, the centering surfaces are arranged in angles of 120 degrees versus each other with respect to a length axis of the camera module.
6. An imaging system according to claim 5 wherein, the camera module comprises three protrusions which are arranged in angles of 120 degrees with respect to each other related to the length axis of the camera module.
7. An imaging system according to claim 6 further comprising, the three protrusions and the three centering surfaces are arranged in angles of approximately 60 degrees versus each other with respect to the length axis of the camera module.
8. An imaging system according to claim 1 wherein, the retainer ring comprises a tubular part and a collar extending radially inwardly from the tubular part.
9. An imaging system according to claim 1 further comprising wherein, the camera module forms a cylindrical shape, and the retainer ring forms a circular ring shape.
