Abstract

A display apparatus for vehicle that can use a space in an instrument panel effectively, minimize a display distortion and allow a vehicle driver to adjust a position of a visible range in an eye range comprises a display unit; a frame; a case; a supporting axis; and a retractable connecting member. The display unit includes a display device, an optical member for magnifying the image, a reflecting member for reflecting the image disposed in between the display device and the optical member, and a cover. The cover is attached to a frame fixed to an opening of the instrument panel for covering the opening. The display device, the optical member and the reflecting member are accommodated in the case integrally. The case is supported rotatably by the supporting axis inside the instrument panel. The retractable connecting member connects the case to the frame.

Claims

1. A display apparatus for vehicle comprising:

a display unit including a display device, an optical member for magnifying a displayed image on the display device, a reflecting member for reflecting the displayed image disposed in between the display device and the optical member, and a cover for covering an opening of an instrument panel of the vehicle;

a frame fixed to the opening;

a case in which the display device, the optical member and the reflecting member are accommodated integrally;

a supporting axis for supporting the case rotatably inside the instrument panel; and

a retractable connecting member for connecting the case to the frame,

whereby a vehicle driver recognizes visually the displayed image of the display unit in an eye range, said display unit being disposed inside the instrument panel, said displayed-image being transmitted through the opening and reflected by an inner surface of a windshield of the vehicle.

3. The display apparatus for vehicle as claimed in claim 1, wherein said reflecting member has complementary reflection characteristics of the inner surface of the windshield for compensating the displayed image distorted by the reflection characteristics of the inner surface of the windshield.

5. The display apparatus for vehicle as claimed in claim 3, wherein the reflecting member further has reflection characteristics for compensating another displaying distortion of the displayed image as a double image caused by both eyes parallax.

7. The display apparatus for vehicle as claimed in claim 1, wherein the optical member is any one of a convex lens, a fresnel lens, and a concave mirror.

9. The display apparatus for vehicle as claimed in claim 1, wherein the cover is formed in a concave shape and attached to the frame at a position where a shield wall of the frame can be seen from the eye range.

2. A display apparatus for vehicle comprising:

a display unit including a display device, an optical member for magnifying a displayed image on the display device, a reflecting member for reflecting the displayed image disposed in between the display device and the optical member, and a cover for covering an opening of an instrument panel of the vehicle;

a frame fixed to the opening;

a case in which the display device, the optical member, the reflecting member and the cover are accommodated integrally;

a supporting axis for supporting the case rotatably inside the instrument panel; and

a retractable connecting member for connecting the case to the frame,

whereby a vehicle driver recognizes visually the displayed image of the display unit in an eye range, said display unit being disposed inside the instrument panel, said displayed image being transmitted through the opening and reflected by an inner surface of a windshield of the vehicle.

4. The display apparatus for vehicle as claimed in claim 2, wherein said reflecting member has complementary reflection characteristics of the inner surface of the windshield for compensating the displayed image distorted by the reflection characteristics of the inner surface of the windshield.

6. The display apparatus for vehicle as claimed in claim 4, wherein the reflecting member further has reflection characteristics for compensating another displaying distortion of the displayed image as a double image caused by both eyes parallax.

8. The display apparatus for vehicle as claimed in claim 2, wherein the optical member is any one of a convex lens, a fresnel lens, and a concave mirror.

10. The display apparatus for vehicle as claimed in claim 2, wherein the cover is formed in a concave shape and attached to the frame at a position where a shield wall of the frame can be seen from the eye range.
