Display device
View Patent ↗A display device has a housing, a video generator, and a mirror. The mirror has a mirror body and a supported portion. The mirror body has a plate shape. The supported portion is provided at at least one end portion in a first direction of the mirror body, and is supported by the housing to be rotatable around a rotating axis along the first direction. The mirror body has a first portion and a second portion. The first portion is located at a position overlapping the supported portion in a second direction crossing a thickness direction and the first direction of the mirror body. The second portion is located at a position different from the supported portion in the second direction. Rigidity per unit width of the first portion in the second direction is greater than rigidity per unit width of the second portion in the second direction.
1. A display device comprising:
a housing;
a video generator configured to project a video; and
a mirror provided inside the housing, and configured to reflect the video projected from the video generator and to project the reflected video to an outside of the housing,
wherein the mirror has:
a plate-shaped mirror body having a reflecting surface; and
a supported portion provided at at least one end portion in a first direction of the mirror body, and supported by the housing to be rotatable around a rotating axis along the first direction,
the mirror body has a first portion located at a position overlapping the supported portion in a second direction crossing a thickness direction and the first direction of the mirror body, and a second portion located at a position different from the supported portion in the second direction, and
rigidity per unit width of the first portion in the second direction is greater than rigidity per unit width of the second portion in the second direction.
2. The display device according to claim 1 , wherein the first portion and the second portion are formed entirely in the first direction of the mirror body.
3. The display device according to claim 1 , wherein the second portion is located at both ends in the second direction of the mirror body.
4. The display device according to claim 1 , wherein a thickness in the first portion of the mirror body is larger than a thickness in the second portion.
5. The display device according to claim 1 , wherein
the reflecting surface is concave in a substantially entire part of the reflecting surface,
a surface on an opposite side of the mirror body from the reflecting surface is convex in a substantially entire part of the surface, and
a curvature of the reflecting surface is smaller than a curvature of the surface on the opposite side.
6. The display device according to claim 1 , wherein the first portion has a rib projecting on an opposite side of the mirror body in respect to the reflecting surface and extending in a projecting line in the first direction.
7. The display device according to claim 1 , wherein a material of the first portion has rigidity greater than rigidity of a material of the second portion.
