Abstract

A combiner-type head-up display device has a simplified lid body opening/closing mechanism. The device has a combiner for reflecting light from an indicator toward the driver side to cause the driver to recognize the light as a virtual image. A holder, to which the combiner is attached, moves in the vertical direction from a stored position to a display position through an aperture. Pins are provided on side surfaces of the holder. A support body has vertical guide grooves for guiding the pins. A vertical drive mechanism is provided for driving the holder in the vertical direction. A lid body which has driven arms, which swing by being pushed by the pins as the pins move vertically as the holder is vertically driven, and opens/closes the aperture. Angle adjustment grooves, which enable pins to rotate about pins with pins abutted on one end of the guide grooves, are provided.

First claim

1 . A head-up display device comprising a combiner which directs and reflects, to a driver side, display light of information to be displayed, the display light being emitted from a display, the head-up display device causing visual recognition due to a virtual image to be achieved in a forward direction of a driver, the head-up display device comprising:
a holder on which the combiner is mounted, and which vertically moves from a storage position to a display position via an opening portion; a pin which is provided on a side face of the holder; a supporting member having a guiding groove in a vertical direction in which the pin is to be guided; vertical driving means for vertically driving the holder; and a lid body having a driven arm which turns while being pressed by the pin that vertically moves concurrently with vertical driving of the holder, the lid body opening or closing the opening portion.

2 . The head-up display device according to claim 1 , wherein an angle adjustment part which adjusts an angle of the combiner at a display position is provided in a guiding groove of the supporting member.

3 . The head-up display device according to claim 1 , wherein biasing means for biasing the lid body in a closed direction is provided at the driven arm.

4 . A head-up display device comprising a combiner which directs and reflects, to a driver side, display light of information to be displayed, the display light being emitted from a display, the head-up display device causing visual recognition due to a virtual image to be achieved in a forward direction of a driver, the head-up display device comprising:
a holder on which the combiner is mounted, and which vertically moves from a storage position to a display position via an opening portion; vertical driving means for elevating the holder; an upper pin and a lower pin which are respectively provided at upper and lower sides of a side face of the holder; and a supporting member having a guiding groove which guides the upper pin and the lower pin, wherein the guiding groove comprises an angle adjustment part in which, in a state in which either one of the upper pin and the lower pin has abutted against an end part of the guiding groove, another pin is turnable on an arc of a circle in which a distance between said one pin and said another pin is defined as a radius about said one pin, and concurrently with elevation of the combiner by the vertical driving means, an angle of the combiner is made adjustable about said one pin by way of the angle adjustment part.

5 . The head-up display device according to claim 4 , having a driven arm which turns while being pressed by the upper pin that moves concurrently with elevation of the holder or by the lower pin,
wherein the driven arm comprises a lid body which opens or closes the opening portion.

6 . The head-up display device according to claim 2 , wherein biasing means for biasing the lid body in a closed direction is provided at the driven arm.
