Abstract

A mirror assembly is coupled to a vehicle and includes a light detection and ranging (LIDAR) sensor, a mirror, and a metallized cover. A conductive mirror base is coupled to the LIDAR sensor, mirror, and metallized cover to form the mirror assembly. The mirror and metallized cover are each grounded to the conductive mirror base where the mirror and metallized cover each help to shield the LIDAR sensor from electromagnetic interference.

First claim

What is claimed is:

1. A mirror assembly for a vehicle comprising:
a light detection and ranging (LIDAR) sensor;
a mirror;
a metallized cover; and
a conductive mirror base coupled to the LIDAR sensor, mirror, and metallized cover to form the mirror assembly;
wherein the mirror and the metallized cover are each grounded to the conductive mirror base to help shield the LIDAR sensor from electromagnetic interference.

2. The mirror assembly of claim 1 , wherein the mirror is a vacuum metallized mirror.

3. The mirror assembly of claim 1 , wherein the metallized cover is a vacuum metallized plastic housing.

4. The mirror assembly of claim 1 , wherein the conductive mirror base comprises a carbon allotrope doped polymer.

5. The mirror assembly of claim 4 , wherein the carbon allotrope doped polymer comprises graphite, graphene, carbon fibers, fullerenes, carbon nanotubes, single-walled carbon nanotubes, multi-walled carbon nanotubes, or combinations thereof.

6. The mirror assembly of claim 4 , wherein the carbon allotrope doped polymer comprises polyethylene terephthalate, nylons, polyacetals, polyacrylates, polycarbonates, polyethylene, low density polyethylene, high density polyethylene, polystyrene, polysulfone, polyvinylchloride, ultra-high molecular weight polyethylene, polytetrafluorethylene, polyether ether ketone, or combinations thereof.

7. The mirror assembly of claim 1 , wherein the conductive mirror base comprises a nylon 6 polymer.

8. The mirror assembly of claim 7 , wherein the nylon 6 polymer is doped with graphite and/or carbon fiber.

9. The mirror assembly of claim 8 , wherein the nylon 6 polymer has a Young's modulus of at least 15 GPa.

10. The mirror assembly of claim 1 , wherein the mirror and the metallized cover transmit at least 70% of near visible light to the LIDAR sensor.

11. The mirror assembly of claim 1 , wherein the mirror and the metallized cover are each coupled to an adhesively bonded lead to ground the mirror and the metallized cover to the conductive mirror base.

12. A mirror assembly for a vehicle comprising:
a conductive mirror base coupled to a light detection and ranging (LIDAR) sensor, a vacuum metallized mirror, and a vacuum metallized cover to form the mirror assembly;
wherein the vacuum metallized mirror and vacuum metallized cover are each grounded to the conductive mirror base through adhesively coupled leads.

13. The mirror assembly of claim 12 , wherein the vacuum metallized mirror and the vacuum metallized cover each help shield the LIDAR sensor from electromagnetic interference.

14. The mirror assembly of claim 12 , wherein the mirror and the metallized cover transmit at least 70% of near visible light to the LIDAR sensor.
