DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflection type display device for a vehicle, which displays various kinds of information on the running state of a vehicle to a driver through a reflection means.

[0002]

2. Description of the Related Art In a vehicle such as a passenger car, a meter unit in which instruments such as a traveling speedometer, an engine tachometer, a fuel gauge, a water temperature gauge, and an indicator lamp are integrated is arranged so that a display surface faces the front of a driver. , On the instrument panel behind the steering wheel.

[0003] Such a conventional meter unit is mounted by mounting means shown in FIG. The instrument panel 1 and the meter unit 2 are respectively provided with four fixing brackets 3 and 4, and each of the brackets 3 and 4 is provided with an insertion hole 6 and a screw hole 7 for a plurality of screws 5. After the meter unit 2 is set on the instrument panel 1 from the horizontal direction and fixed with a plurality of screws 5, the male connector 9 of the wire harness 8 is connected to the meter unit 2 from the rear of the meter unit 2 in the instrument panel 1. The attachment is performed by manually connecting to a female connector (not shown).

[0004]

In the above prior art, the male connector 9 of the wire harness 8 must be connected in the instrument panel 1 by blind work, and the workability involved in the connection is poor.

An upper reflecting section 60 is provided to reflect the image light toward the eye point 43.

The operation (action) will be briefly described, but the reflected light directed to the eye point 43 will give the user the feeling that the display unit 53 is located behind the windshield 59 (in the forward direction of the vehicle). An image such as a scale of a dial (not shown) is visually recognized as a virtual image.

In the case of the above-described embodiment, it is possible to further increase the distance from the display unit 53 as in the other embodiments described above, and the driver 22 almost shifts his / her line of sight while the vehicle is running. Since various kinds of information can be obtained as a virtual image without any problem, there is an advantage that visibility can be significantly improved.
