Abstract

Claims (27)

1. An automotive trim component, the component comprising:

a lightguide assembly configured to generate light and for directing the generated light;

a front cover comprising a combination of a transparent or translucent resin and a non-transparent or non-translucent resin; and

a back cover configured to define an optical channel between the back cover and the front cover and act as a carrier for the lightguide assembly within the optical channel,

wherein:

the back cover comprises an electrical harness and a rib disposed around at least a portion of the lightguide assembly, and

the rib is configured to contain and support the electrical harness within the optical channel.

2. The component of claim 1 , wherein the component comprises a lamp assembly for a vehicle.

3. The component of claim 2 , wherein the lamp assembly comprises part of a grille assembly of the vehicle.

4. The component of claim 1 , wherein the non-transparent or non-translucent resin is an opaque resin.

5. The component of claim 1 , wherein the transparent or translucent resin is composed of one or more of polycarbonate (PC) or poly(methyl methacrylate) (PMMA), and the non-transparent or non-translucent resin is composed of one or more of acrylonitrile butadiene styrene (ABS), PC, PMMA, or acrylonitrile styrene acrylate (ASA).

6. The component of claim 5 , wherein the non-transparent or non-translucent resin is a metallic plateable resin.

7. A method of manufacturing an automotive trim component, the method comprising:

providing a lightguide assembly configured to generate light and for directing the generated light;

forming a front cover comprising a combination of a transparent or translucent resin and a non-transparent or non-translucent resin; and

forming a back cover configured to define an optical channel between the back cover and the front cover and act as a carrier for the lightguide assembly within the optical channel, the back cover comprising an electrical harness and a rib disposed around at least a portion of the lightguide assembly, the rib being configured to contain and support the electrical harness within the optical channel.

8. The method of claim 7 , wherein the component comprises a lamp assembly for a vehicle.

9. The method of claim 8 , wherein the lamp assembly comprises part of a grille assembly of the vehicle.

10. The method of claim 7 , wherein the forming the front cover further comprises using a multi-shot injection molding process to form the front cover.

11. The method of claim 10 , wherein the transparent or translucent resin is composed of one or more of polycarbonate (PC) or poly(methyl methacrylate) (PMMA), and the non-transparent or non-translucent resin is composed of one or more of acrylonitrile butadiene styrene (ABS), PC, PMMA, or acrylonitrile styrene acrylate (ASA).

12. The method of claim 11 , wherein the non-transparent or non-translucent resin is a metallic plateable resin formed via an electroplating deposition technique.

13. A front grille assembly for a vehicle, the front grille assembly comprising an automotive lamp assembly comprising:

a lightguide assembly configured to generate light and for directing the generated light;

a front cover comprising a combination of a transparent or translucent resin and a non-transparent or non-translucent resin; and

a back cover configured to define an optical channel between the back cover and the front cover and act as a carrier for the lightguide assembly within the optical channel, the back cover comprising an electrical harness and a rib disposed around at least a portion of the lightguide assembly, the rib being configured to contain and support the electrical harness within the optical channel.

14. The lamp assembly of claim 13 , wherein the non-transparent or non-translucent resin is an opaque resin.

15. The lamp assembly of claim 13 , wherein the transparent or translucent resin is composed of one or more of polycarbonate (PC) or poly(methyl methacrylate) (PMMA), and the non-transparent or non-translucent resin is composed of one or more of acrylonitrile butadiene styrene (ABS), PC, PMMA, or acrylonitrile styrene acrylate (ASA).
