Rearview assembly
A rearview assembly having a transflective element, a carrier plate, and an imager. The transflective element may have a first side and a second side in a first direction relative the first side. The carrier plate has a third side and a fourth side. The third side is adhered to the second side and extends substantially there along. The carrier plate may also have a cavity extending from the third side in the first direction. The cavity may have a first aperture, a second aperture, and an end portion. The first aperture may be at the third side. The second aperture may be disposed in the first direction relative the first aperture. The end portion may circumscribe the second aperture. The imager may extend through the second aperture and comprise a light collection portion, which is disposed proximate the second side.
1 . A rearview assembly comprising:
a transflective element having a first side and a second side, the second side in a first direction relative the first side;
a carrier plate having a third side and a fourth side, the third side adhered to the second side, the carrier plate defining a cavity therethrough, wherein the cavity is cylindrical, the cavity having:
a first aperture at the third side adjacent the transflective element;
a second aperture disposed in the first direction relative the first aperture and having a smaller diameter than a diameter of the first aperture;
an imager receiving recess disposed in the first direction relative the second aperture and having a diameter that is smaller than the diameter of the first aperture; and
an end portion circumscribing the second aperture; and
an imager operable to capture light and produce an image, the imager extending through the second aperture and comprising a light collecting portion disposed proximate the second side.
2 . The rearview assembly of claim 1 , wherein the light collecting portion is disposed less than 5 mm from the second side.
3 . The rearview assembly of claim 1 , wherein the imager fills the second aperture.
4 . The rearview assembly of claim 1 , wherein the carrier plate further comprises a lip portion, the lip portion circumscribing the first aperture and comprising:
an interior edge,
an exterior edge circumscribing the interior edge, and
a connecting surface extending between the interior edge and the exterior edge.
5 . The rearview assembly of claim 4 , wherein the lip portion is raised in a second direction relative the third side, the second direction opposite the first direction.
6 . The rearview assembly of claim 4 , wherein the interior edge is in abutting contact with the second side.
7 . The rearview assembly of claim 4 , wherein the interior edge may define the first aperture.
8 . The rearview assembly of claim 4 , wherein the connecting surface is sloped relative the third side.
9 . The rearview assembly of claim 1 , wherein the cavity has side walls extending between the first aperture and the end portion.
10 . The rearview assembly of claim 9 , wherein the side walls are perpendicular relative the third side.
11 . The rearview assembly of claim 1 , wherein the first aperture is larger than the second aperture and the imager receiving recess.
12 . The rearview assembly of claim 1 , wherein surfaces of the cavity are anti-reflective.
13 . The rearview assembly of claim 1 , wherein the transflective element is variably reflective upon application of a voltage to the transflective element.
14 . The rearview assembly of claim 2 , wherein the transflective element comprises:
a first substrate having a first surface and a second surface;
a second substrate disposed substantially parallel the first substrate and having a third surface and a fourth surface;
a first electrode associated with the second surface;
a second electrode associated with the third surface; and
an electro-optic medium disposed between the first and second electrodes.
15 . The rearview assembly of claim 1 , wherein the carrier plate is adhered to the second side via an adhesive foam layer.
16 . The rearview assembly of claim 4 , wherein:
the carrier plate is adhered to the second side via an adhesive foam layer; and
the carrier plate does not make direct contact with the transflective element except via the lip portion.
