Apparatus and system for providing a virtual display for a vehicle

1. A display unit for mounting in a vehicle, comprising:

an image generator; and

a semi-reflective member, configured to move from a non-operational position to an operation position, wherein the semi-reflective member is positioned to reflect light from the image generator in the operational position;

a threaded rod rotated by a motor;

a carriage having a threaded member, wherein the carriage is pivotably coupled to the semi-reflective member and the carriage is configured to move along the threaded rod by the rotation of the threaded rod;

a frame comprising a first rail and a second rail that remain stationary as the semi-reflective member is moving;

a first trolley device and a second trolley device configured to ride along the first rail and the second rail, wherein the first and second trolley devices are pivotably coupled to the semi-reflective member;

wherein, as the carriage rides along the threaded rod and the first and second trolley devices ride along the first and second rails, the pivotal couplings of the carriage and the trolleys with the semi-reflective member are configured to cause the semi-reflective member to move longitudinally and rotationally into the operational position.

2. The display unit of claim 1 , further comprising a housing that remains stationary as the semi-reflective member moves from the non-operational position to the operational position, wherein the motor remains stationary relative to the housing.

3. The display unit of claim 1 , wherein the semi-reflective member is moved rotationally and longitudinally as the semi-reflective member is caused to transition from the operational position to the non-operational position.

4. The display unit of claim 1 , wherein the housing includes a first door and a second door, wherein the first door covers a distal end of the semi-reflective member when in the non-operational position.

5. The display unit of claim 1 , wherein the housing includes a first door and a second door, wherein the second door covers the image generator.

6. The display unit of claim 5 , wherein the first door covers a distal end of the member when in the non-operational position, wherein the second door covers the image generator.

7. The display unit of claim 6 , wherein the doors are pivotably coupled to at least one of the trolleys and the semi-reflective member and wherein the doors are configured to open, via the pivotal couplings, as the semi-reflective member moves to the operational position.

8. The display unit of claim 1 , wherein the threaded rod rotates relative to the housing but does not change horizontal or vertical position relative to the housing; and wherein the threaded rod is substantially parallel to the semi-reflective member when the semi-reflective member is in the non-operational position and wherein the threaded rod is substantially perpendicular to the semi-reflective member when the semi-reflective member is in the operational position.

9. A method of using a virtual display device including a semi-reflective member and an image display, the method comprising:

moving the semi-reflective member from a non-operational position to an operational position by rotating a threaded rod, thereby causing a carriage to ride along the threaded rod and causing first and second trolley devices to ride along first and second rails of the virtual display device;

wherein, as the carriage rides along the threaded rod and the first and second trolley devices ride along the first and second rails, pivotal couplings of the carriage and the trolleys with the semi-reflective member cause the semi-reflective member to move longitudinally and rotationally into the operational position; and further comprising:

displaying a virtual image by projecting an image to the semi-reflective member from the image display.

10. The method of claim 9 , further comprising:

opening at least one door on a housing; and

opening at least a second door blocking an optical path between the semi-reflective member and the image display.

11. The method of claim 10 , wherein opening the second door causes the at least one door to open.

12. The method of claim 9 , wherein movement of the carriage and the semi-reflective member causes the at least one door on the housing and the at least a second door to open.

13. The method of claim 9 , wherein the semi-reflective member and the at least one door are moved by a motion of a single motor configured to rotate the threaded rod.

14. A virtual image system for a vehicle, the virtual image system being disposed in or above a dashboard of a ground vehicle, the virtual image system comprising:

a display; and

a frame having rails and a threaded rod;

a motor coupled to the frame and configured to rotate the threaded rod;

a semi-reflective member configured to be caused to move longitudinally and rotationally by the motor's rotation of the threaded rod;

wherein the movement is from a non-operational horizontal position to an upright operational position, wherein the upright operational position is substantially perpendicular to the horizontal position and the dashboard.

15. The virtual image system of claim 14 , further comprising a housing, the housing comprising a first door and a second door, wherein the first door is opened to allow the semi-reflective member to be positioned at least partially outside the housing and the second door is moved to provide an optical path between the display and the semi-reflective member.

16. The virtual image system of claim 15 , wherein the optical path does not include separate lenses.

17. The virtual image system of claim 15 , wherein movement of the semi-reflective member on the rails causes the first door and the second door to open.

18. The virtual image system of claim 14 , wherein the semi-reflective member rides on the rails via trolleys.
