Description

[Detailed Description of the Invention] This invention relates to a projection device for a speedometer of an automobile.

Generally, drivers do not constantly look at the speedometer while driving a car. This is because the speedometer is out of the driver's field of vision while driving, so to check the speed, you have to lower your eyes and take the trouble to look at the speedometer. Therefore,
Surprisingly, there are many cases in which drivers drive without knowing the exact driving speed, and when they try to look at the speedometer, their line of sight deviates, albeit momentarily, and they become inattentive to the road ahead, which can be dangerous.

The present invention was developed with the aim of preventing such dangers, and aims to provide a speedometer projection device that allows the user to easily check the traveling speed without having to constantly look at the speedometer while driving. It is something to do.

For this purpose, the gist of the present invention is to provide a mirror body above the speedometer of a car installed in its normal position, and the mirror body is configured to project an image of the speedometer onto a part of the windshield. It is something.

Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiment. Reference numeral 1 is a speedometer attached to an instrument panel, and the speed can be digitally displayed on a liquid crystal display. 2 is a mirror body attached to the upper hood 3 of the instrument panel;
The speed display 1a of the speedometer 1 can be projected on the lower part of the windshield 4. That is, the mirror body 2 has a window hole 3a provided in the upper hood 3.
A mirror surface 2a is installed at a position facing the speedometer 1 through the mirror surface 2a, and a speed display 1 is displayed on the mirror surface 2a.
It is installed at an angle that allows it to reflect the light and project it onto the windshield 4.

Since the present invention is constructed as described above, the running speed can be determined by looking at the number 4a printed on the lower part of the windshield 4. Therefore, the speed can be determined without looking at the speedometer 1 every time, and since the number 4a is within the driver's field of vision, it can be seen at all times, which is extremely convenient for safe driving.

The mirror body 2 is not limited to a plane mirror, but may be a concave mirror or a convex mirror, and by appropriately setting it, it is possible to adjust the size and shape of the projected numbers 4a. It can also be a mirror or a half mirror. Further, the mirror body 2 can be configured not only in a fixed type but also in a movable type, and in some cases, it may be possible to open and close the mirror body by a voice command.

As explained above, according to the present invention, the driver can check the speed display projected on the windshield while looking ahead, and there is no need to lower his/her line of sight to look at the speedometer. It has the effect of preventing danger. In addition, since you can always know the speed,
It is possible to prevent the sense of speed from becoming dull on expressways, etc., and ensure safe driving.
