Abstract

PURPOSE:To permit a various sorts of information of a car to be easily recognized at night by allowing the characters and fixed images on a character plate to be projected onto the road surface at the position immediately before front wheels by the light passing through a small lens for image projection which forms a part of a headlight lens. CONSTITUTION:On the wall parts 2A and 2B of a front cowling under a small lens 8 for image projection which is formed integrally with the lower wall part 7 of a headlight lens 6, openings 2a and 2b are formed, and a character plate 10 is installed onto the opening 2a. The light of a lamp 9 is projected onto the road immediately before front wheels through the lens 8, character plate 9, and the openings 2a and 2b. The character image displayed onto the character plate 10 is reversed and magnified and projected onto the road by the operation of the information switch attached onto a steering wheel H.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device for small vehicles such as motorcycles and tricycles, and particularly to information display technology using a head rung device.

An instrument panel is provided at the steering wheel of a running vehicle, so that the minimum amount of information necessary for driving, maintenance, or inspection can be obtained. However, when you want to obtain information other than the information that can be obtained from the instrument panel, or when you want to display information that can be obtained from the instrument panel in a size that is easier to see, in small vehicles such as motorcycles, However, it was difficult to meet that demand.

The present invention was devised under such circumstances, and
The purpose of this is to display various information using the headlamp device.

The structure of the present invention is to include text and/or graphic images in the light extracted through a part of the headlight lens, and to project the text and/or graphic images onto the road surface in front of the front wheels. It is a feature.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 8. FIG. 1 shows a motorcycle 1 as a left side view.
At the front of the motorcycle body, there is a front cowling 2.
is arranged, and an instrument panel 3 is arranged in front of the handle H.

Further, a headlight lens 6 of a headlamp device 5 having a large width is located in an opening 4 formed at the forefront of the front cowling 2. The light emitted from the lamp 9 of the headlamp device 50 is
Transmitted through lens 6.

The light beams are radiated at predetermined light distribution angles as a running beam B+ (solid line) and a misaligned beam B2 (two-dot chain line) (see FIGS. 1 and 2).

Thus, the headlight lens 6 has a U-shaped cross section.
A small image projection lens 8 is provided on the lower wall portion 7 of the
are integrally formed. The walls 2A and 2B of the front cowling 2, which cover the lower part of the small image projection lens 8, each have an opening 2a.

21) is formed, and the dial 10 is attached to the opening 2a. The dial 10 uses a liquid crystal (a color liquid crystal may be used), and is connected to a control device (not shown) housed in the instrument panel 3 through a conductor 11, and is connected to an information changeover switch attached to the handle H. (not shown),
The dial plate has a structure on which various characters are displayed.

The light from the lamp 9 is transmitted through a small image projection lens 8. Dial board 10
．． The light is projected onto the road surface in front of the front wheel FW through the openings 2a and 2b7 (see Figures 1 and 3 above).
.

The information displayed on the dial 10 may be information indicating the vehicle status, such as vehicle speed (see Figure 4, unit km), m fuel remaining amount (see Figure 5, unit), or time (see Figure 6). ), temperature (in 2 units °C, see Figure 7), etc.

This embodiment is configured as described above, and when driving at night,
When the lamp 9 is turned on, the light passes through the small image projection lens 8
and is projected onto the road surface via the dial 10. Note that this projected light (B3) is projected onto the road surface at a much larger angle than the 1-passing beam B2, so it does not overlap with the passing beam B2.

When any of the above information is displayed on the dial plate 10 by operating the information changeover switch attached to the non-dollar H, the character image is inverted, enlarged, and projected onto the road surface (see Figures 5 and 5). See Figure 8.

However, FIG. 8 is a conceptual diagram showing a state in which the character images on the dial plate 10 are projected onto the road surface S).

In the above embodiment, the image projection small lens 8 is formed integrally with the headlight lens 6, but it may be formed as a separate lens and attached to the lower wall portion 7 of the headlight lens 6. Alternatively, instead of providing the image projection lens on the lower wall portion 7, two lenses may be attached to the openings 2a and 2b to form a character image on the road surface. Also, dial 1
Instead of 0, a plate with a character image (for example, vehicle owner name, vehicle manufacturer name, etc.) simply punched out may be attached to the opening 2a. Or, without using a separate dial,
The character image may be formed by punching directly onto the cover of the headlamp device.

Furthermore, if a shutter that is opened and closed by a solenoid or the like is attached to the opening 2a or 2b, and the shutter is opened and closed by operating the information changeover switch, character images can be projected only when necessary.

Furthermore, instead of the dial plate 10, a compass made of a transparent material is attached to the opening 23, excluding the magnetic needle.

``Just like projecting the image of a magnetic needle, you can easily determine your direction, which is useful when driving in geographically unfamiliar places.

As is clear from the description of the embodiments, one aspect of the present invention includes characters and/or graphic images extracted through a part of the headlight lens, and the characters and/or graphic images are placed directly in front of the front wheels. Since it is projected onto the road surface at the location, various information indicating the vehicle status etc. can be displayed in a form that is easy to visually recognize at night.
