Abstract

A vehicle add-on part for integrating a camera module includes a cover, which consists at least partially of a transparent thermoplastic material, a carrier part for a camera module, and a camera module having at least one camera lens. The transparent thermoplastic material of the cover has, on the inner side, a local thickening and/or a local thinning, and the camera module is held in the carrier part such that the at least one camera lens of the camera module is arranged directly opposite the thickening and/or the thinning.

First claim

The invention claimed is:

1. A vehicle add-on part having an integrated camera module, comprising:
a cover with an outer side and an inner side, wherein the cover consists, at least in sections, of a transparent thermoplastic material;
a carrier part that is arranged on the inner side of the cover and in which a camera module is arranged;

wherein the cover has, on the inner side, a local thickening and/or a local thinning of the transparent thermoplastic material;
and wherein the camera module includes at least one camera lens and is arranged in the carrier part such that the at least one camera lens is arranged directly opposite the local thickening and/or the local thinning, said carrier part being made of a material that is absent between the at least one camera lens and a region of the local thickening and/or the local thinning that is directly opposite the at least one camera lens such that said region of the local thickening and/or the local thinning terminates in a materially integral manner or substantially flush with the at least one camera lens.

2. The vehicle add-on part according to claim 1 , wherein the outer side of the cover has substantially the form of a planar surface or a curved surface.

3. The vehicle add-on part according to claim 1 , wherein the vehicle add-on part is a front window, a rear window, a side window, a roof panel, a trim strip, a bumper, a sill, a spoiler, a lamp cover, or a panel.

4. The vehicle add-on part according to claim 1 , wherein structures are introduced into the transparent thermoplastic material of the cover on the inner side in the direction of the camera lens.

5. The vehicle add-on part according to claim 1 , wherein the material of the carrier part for the camera module is made of a thermoplastic material.

6. The vehicle add-on part according to claim 5 , wherein a recess for holding the camera module is introduced into the thermoplastic material of the carrier part.

7. The vehicle add-on part according to claim 5 , wherein the cover is entirely made of transparent thermoplastic material.

8. The vehicle add-on part according to claim 1 , wherein the vehicle add-on part includes a polymeric film.

9. The vehicle add-on part according to claim 1 , wherein the cover is coated, at least on the outer side, with a protective coating.

10. A method for producing a vehicle add-on part having an integrated camera module that includes at least one camera lens, the method comprising:
in a first step, producing, by means of an injection molding process, a cover that consists, at least in sections, of a transparent thermoplastic material and that has, on its inner side, a local thickening and/or a local thinning of the transparent thermoplastic material, and
in a second step, injection molding a carrier part made of thermoplastic material for the camera module that includes at least one camera lens onto the cover, on the inner side;
or
in a first step, producing, by means of an injection molding process, a carrier part made of a thermoplastic material for the camera module that includes at least one camera lens, and
in a second step, molding a cover that is made, at least in sections, of a transparent thermoplastic material and has, on its inner side, a local thickening and/or a local thinning of the transparent thermoplastic material, onto the carrier part such that the inner side of the cover is connected to the carrier part;
in a third step, holding the camera module in the carrier part such that the at least one camera lens is arranged directly opposite the local thickening and/or the local thinning,
wherein the thermoplastic material of said carrier part is absent between the at least one camera lens and a region of the local thickening and/or the local thinning that is directly opposite the at least one camera lens such that said region of the local thickening and/or the local thinning terminates in a materially integral manner or substantially flush with the at least one camera lens.

11. The method according to claim 10 , wherein the cover and the carrier part connected thereon are produced in the 2-component injection molding process or in the 2-component injection-compression molding process with turning platen technology.

12. A method for producing a vehicle add-on part having an integrated camera module that includes at least one camera lens, the method comprising:
in a first step, producing as a 1-component injection molded part with a back-injected polymeric film a cover that is made, at least in sections, of a transparent thermoplastic material and that has, on its inner side, a local thickening and/or a local thinning of the transparent thermoplastic material, wherein the film is arranged on the inner side of the cover;
in a second step, providing a carrier part for the camera module;
in a third step, attaching the carrier part on the back-injected polymeric film, and
in a fourth step, holding the camera module that includes at least one camera lens in the carrier part such that the camera lens is arranged directly opposite the local thickening and/or the local thinning,
wherein said carrier part is made of a material that is absent between the at least one camera lens and a region of the local thickening and/or the local thinning that is directly opposite the at least one camera lens such that said region of the local thickening and/or the local thinning terminates in a materially integral manner or substantially flush with the at least one camera lens.

13. The method according to claim 10 , wherein an injection molding compound is introduced, during production of the cover, via a lateral fan sprue and/or lateral injection points and/or via an injection point in the region of the local thickening and/or the local thinning.

14. The method according to claim 10 , wherein a protective coating is applied at least on an outer side of the vehicle add-on part or of the cover and/or of the carrier part.

15. A method comprising utilizing a vehicle add-on part according to claim 1 for integrating a camera module in a vehicle.

16. The vehicle add-on part according to claim 4 , wherein the structures include curvatures, prisms, or Fresnel optics.

17. The vehicle add-on part according to claim 5 , wherein the thermoplastic material of the carrier part is an opaque thermoplastic material.

18. The vehicle add-on part according to claim 7 , wherein the cover and the carrier part are implemented as a 2-component injection molded part.

19. The vehicle add-on part according to claim 8 , wherein the polymeric film is a back-injected polymeric film, which is arranged between the cover and the carrier part.
