JPH10181469A - Vehicle provided with speed indicating means - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable a third person to surely discriminate the speed of a vehicle by providing a suitable place of a vehicle with a speed indicating means seen from the outside. SOLUTION: As a speed indicating means, a light emitting unit adapted to emit light in different colors depending upon the speed is adopted, and the unit is mounted on a blank space or the like of the surface of a number plate P. This light emitting unit L may be formed as one sheet material, but it is formed by arranging four sheets by units of light emitting units Ln adapted to emit light in different colors depending on the speed. In order to facilitate discrimination of colors, as an example, the colors of the colored glasses are four colors, green, blue, orange-color and red from the left. Lighting of four kinds of light emitting elements (lamp) L1-L4 is performed by detecting the speed of a vehicle by a car speed sensor, discriminating the speed by a microcomputer, and outputting the discrimination result to one of relays for lighting the respective light emitting elements L1-L4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle provided with speed display means.

[0002]

2. Description of the Related Art From the viewpoint of suppressing the speed for safety, it is preferable that the speed of a vehicle such as an automobile can be distinguished from others. That is, if an oncoming vehicle, a following vehicle, or a pedestrian or the like knows the speed of the vehicle that they drive, the driver's psychology tends to suppress the speed.
On the other hand, those who always keep the speed in mind may want to make this known to others. For this reason,
For heavy trucks, etc., it is mandatory to have a mechanism to increase the number of lighting of lamps as the speed increases.

[0003]

However, since this lamp is mounted on the upper part of the windshield, it can only be seen from the front, and its position is poor, making it difficult to see. or,
Since the determination is made based on the number of lighting of the lamps, it may not be possible to distinguish them. The present invention solves this problem by providing the speed display means at a position where it is easy to see.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a vehicle provided with speed display means, characterized in that speed display means visible from the outside is provided at an appropriate position on the vehicle. is there. In this case, the speed display means may be of any type. For example, the speed display means may be formed of a luminous body that emits light of different colors depending on the speed. Suitably composed of individual or side-by-side arrangements. According to the luminous body, it can be visually recognized at night as well as during the day.

[0005] The location where the speed display means is provided may be any location as long as it can be seen from outside, regardless of inside or outside of the vehicle. Specifically, a license plate is conceivable. or,
Other than the license plate, a portion that can be easily seen from the outside, for example, a front or rear portion or a side of the body can be considered. The speed display means allows an oncoming vehicle, a following vehicle, a pedestrian, and the like to determine the speed at a glance.

Further, as another aspect of the present invention, there is provided a means provided with a means for preventing freezing of moisture and the like adhering to the luminous body and the vicinity thereof, and a means wherein the means for preventing freezing comprises a hot wire heater. There are many cold regions in Japan, including Hokkaido and Tohoku. For this reason, even if the luminous body as the speed display means is attached, the speed cannot be determined if the luminous body is frozen. In addition, if this anti-freezing means is extended from the light-emitting body and applied to, for example, a license plate as a whole, it is possible to prevent a situation in which the numbers and the like are not visible due to freezing.

[0007]

Embodiments of the present invention will be described below. In short, in the present invention, it is sufficient that the speed display means is provided at an appropriate position on the surface of the vehicle. The speed display means may be of any type. In short, it is only necessary to detect the traveling speed and display it in digital or analog form. The location where the speed display means is provided may be anywhere, as long as it can be visually recognized from the outside. In particular,
One or both license plates before and after are considered,
Other than these, the front and rear parts or the side of the body that do not hinder driving are conceivable.

FIG. 1 is a front view of a license plate showing an example of the present invention. As a speed display means, a luminous body L that emits light of different colors depending on the speed is adopted, and this is used as a margin on the surface of the license plate P. And so on. The light-emitting element L may be a single light-emitting element, but in this example, the light-emitting element Ln is configured by arranging four light-emitting elements Ln that emit light in different colors at different speeds. It should be noted that the arrangement form is not limited, but it is not preferable to arrange them so far apart.

The light-emitting element Ln also has various structures, but the most common one is to house a lamp in colored glass and emit light in that color. still,
In addition, a light emitting diode can be used. In the present example, the color of the colored glass is shown as four colors of green, blue, orange, and red from the left for easy color discrimination, but the number of colors and color types are not limited thereto.

FIG. 2 shows the above four types of light emitting elements (lamps).
This is an example of an electric circuit diagram for lighting L1 to L4. The speed of a vehicle is detected by a vehicle speed sensor SS, and this is detected by a microcomputer MC.
A relay X that lights up each of the light emitting elements L1 to L4 as determined by
1 to X4. The vehicle speed sensor SS used here may be of any type.
In general, the data is read by C and output to each of the relays X1 to X4 for each frequency.

The speed and the color coding of the light emitting elements L1 to L4 are as follows.
For example, if the speed is 40 km / h or less, none of the lights are turned on.
If it is in the range of 0 to 60 km / h, the blue light turns on and 60 to 8 km / h.
If it is in the range of 0 km / hour, green light is turned on, and 80-100K.
It is conceivable that orange lights up in the range of m / hour and red lights up above 100 km / hour. The relationship between speed and color can be naturally remembered if this license plate becomes popular.

FIG. 3 is a perspective view of a vehicle showing another example of the present invention. As described above, the luminous body L may be attached to the rear portion of the vehicle (the rear window W in this example). Of course, other than this, it may be attached to the front part or the side part. However, it goes without saying that the size of the light-emitting body L and the location where the light-emitting body L is attached are within a range that does not hinder driving.

By the way, the luminous body L may be provided with a means for preventing freezing of water adhering to its surface. This is because the luminous body L cannot be seen when the moisture is frozen. In addition, if the anti-freezing means is extended to the periphery of the illuminant, the frost is prevented over a wide range, and if the illuminant L is attached to a license plate, the number may be frozen and cannot be seen. Can be prevented.

There are various specific means for preventing the freezing, but the most common one is to attach a hot wire heater H inside or on the front and back surfaces and turn it on and off with a switch SW (FIG. 2). In addition to this, it is also conceivable to blow warm air or physically scrape the air.

The above speed display means is mounted on any vehicle. Specifically, it is not limited to special vehicles such as passenger cars, wagons, 4WDs, large and small trucks, and crane vehicles, as well as motorcycles, motorcycles, and motorcycles.

[0016]

As described above, according to the present invention, the speed of the vehicle can be reliably determined by the third party by means of the speed display means, so that the driver's psychology is moderate and the safe driving can be performed. If the speed display means is provided with the anti-freezing means, there is no situation in which the water is frozen and cannot be seen.
