Abstract

A display device applied to an instrument panel unit includes: a projection surface provided on a surface on a vehicle interior side of an interior member provided on the vehicle interior side of a vehicle and on a front side in a vehicle front-back direction, the interior member extending along a vehicle width direction; a projector including a projection unit configured to project an image; and a holding unit configured to hold the projector by the interior member in a positional relationship where at least a part of the projection unit is located on the projection surface side of the interior member, and the image from the projection unit is projected onto the projection surface.

First claim

What is claimed is:

1. A display device for a vehicle having a windshield, comprising:
a projection surface directly provided on a surface on a vehicle interior side of an interior member provided on the vehicle interior side of a vehicle and on a front side in a vehicle front-back direction, the interior member extending along a vehicle width direction intersecting with the vehicle front-back direction and being independent of the windshield;
a projector including a projection unit configured to project an image; and
a holding unit configured to hold the projector by the interior member, or a structural member to support the interior member on the vehicle interior side on a side opposite to the projection surface, in a positional relationship where at least a part of the projection unit is located on the projection surface side of the interior member,
wherein the projection unit projects the image onto the projection surface in a downward direction towards a floor of the vehicle,
the interior member includes a hood unit located on the projection surface side of the interior member, the hood unit including an opening on the projection surface side, and
the projector is configured to be incorporated into meter equipment provided in the hood unit.

2. The display device according to claim 1 , wherein
the projection unit includes a reflection unit configured to reflect projection light representing the image onto the projection surface.

3. The display device according to claim 2 , wherein
the reflection unit includes a magnifying mirror configured to magnify and reflect the image represented by the projection light.

4. The display device according to claim 3 , wherein
the reflection unit includes a freeform surface mirror configured to correct a distortion of the image represented by the projection light and reflect the image.

5. The display device according to claim 2 , wherein
the reflection unit includes a freeform surface mirror configured to correct a distortion of the image represented by the projection light and reflect the image.

6. The display device according to claim 2 , wherein
the projection surface is provided on a side opposite to a driver's side of the vehicle relative to the center of the interior member in the vehicle width direction, and
the projector projects, onto the projection surface, the image including blind-spot information on a passenger's side when viewed from the driver's side.

7. The display device according to claim 1 , wherein
the projection surface is provided on a side opposite to a driver's side of the vehicle relative to the center of the interior member in the vehicle width direction, and
the projector projects, onto the projection surface, the image including blind-spot information on a passenger's side when viewed from the driver's side.

8. The display device according to claim 1 , wherein
the holding unit is configured to hold the projector by the interior member in a positional relationship where at least a part of the projection unit is located on the projection surface side of the interior member, and the image from the projection unit is projected onto the projection surface.

9. The display device according to claim 1 , wherein
the projection surface is provided on an instrument panel.

10. The display device according to claim 1 , wherein
the projector is provided on a side opposite to a driver's side of the vehicle relative to the center of the interior member in the vehicle width direction.

11. An interior member unit comprising:
an interior member provided on a vehicle interior side of a vehicle having a windshield and on a front side in a vehicle front-back direction, the interior member extending along a vehicle width direction intersecting with the vehicle front-back direction and being independent of the windshield;
a projection surface directly provided on a surface on the vehicle interior side of the interior member;
a projector including a projection unit configured to project an image; and
a holding unit configured to hold the projector by the interior member in a positional relationship where at least a part of the projection unit is located on the projection surface side of the interior member,
wherein the projection unit projects the image onto the projection surface in a downward direction towards a floor of the vehicle,
the interior member includes a hood unit located on the projection surface side of the interior member, the hood unit including an opening on the projection surface side, and
the projector is configured to be incorporated into meter equipment provided in the hood unit.

12. A display device for a vehicle having a windshield, comprising:
a projection surface directly provided on a surface on a vehicle interior side of an interior member provided on the vehicle interior side of a vehicle and on a front side in a vehicle front-back direction, the interior member extending along a vehicle width direction intersecting with the vehicle front-back direction and being independent of the windshield;
a projector including a projection unit configured to project an image; and
a holding unit configured to hold the projector by the interior member, or a structural member to support the interior member on the vehicle interior side on a side opposite to the projection surface, in a positional relationship where at least a part of the projection unit is located on the projection surface side of the interior member, and the image from the projection unit is projected onto the projection surface,
wherein the projection surface does not transmit light,
the projection unit projects the image onto the projection surface in a downward direction towards a floor of the vehicle,
the interior member includes a hood unit located on the projection surface side of the interior member, the hood unit including an opening on the projection surface side, and
the projector is configured to be incorporated into meter equipment provided in the hood unit.
