JPH06298024A - Rear-end collision prevention and crime prevention device - Google Patents

Abstract

PURPOSE:To prevent a vehicle parking on a road with its lamps turned off at night from being collided from behind. CONSTITUTION:A light receiving circuit 8 for detecting the light of a lamp is mounted at the rear part of a vehicle. When the light receiving circuit 8 detects the light, a number plate 2 and/or a flickering lamp are lighted to tell the existence of a parking vehicle to a driver in a rear vehicle. At night, characters in the number plate 2 are made luminous to read them even without approaching the vehicle, so it is possible to provide a crime protection effect.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of quickly detecting the presence of a vehicle parked at night on the road to prevent a rear-end collision, and at the same time, the license plate of the vehicle parked at night approaches the parked vehicle. The present invention relates to a rear-end collision prevention and crime prevention device devised so that it can be read at all.

[0002]

2. Description of the Related Art At night, in the case of a car parked on the road with the light off, there is currently no other way than to confirm this with the headlight of the car. In addition, a license plate that is parked on a road with the night light turned off is difficult to read unless it is approached and illuminated by a flashlight or the like because the indicator light on the license plate is off.

[0003]

For this reason, there are many examples of accidents in which a vehicle is parked on the road at night and hits a large vehicle in particular. In addition, if there is a vehicle stopped at a curve or the like, this finding is often delayed, resulting in an accident. Also, if you try to check the license plate for a criminal investigation, etc. for a car that has been turned off at night, it is difficult to read the number unless you approach the car. In some cases, in the case of an escape vehicle, there is also an example of turning off the light so that the license plate cannot be read.

An object of the present invention is to prevent a rear-end collision accident and to propose a rear-end collision prevention and crime prevention device effective for crime prevention.

[0005]

The structure of the rear-end collision and crime prevention device according to the present invention is as follows.

[0006] A rear-end collision prevention and crime prevention device in which a light receiving circuit for receiving light from a vehicle and outputting a signal is attached to the rear of the vehicle and a light emitting body which emits light according to the signal from the light receiving circuit is attached to the rear of the vehicle. .

[0007]

When the light receiving circuit receives light from a light such as an automobile, a motorcycle, or a flashlight, a signal is output, and the light emitter emits light by this signal. This light emission is extinguished while the light of the light is being received or after no light is received for a certain period of time.

[0008]

[Embodiment] FIG. 1 shows an EL for a license plate 2 of an automobile 1.
In this embodiment, the license plate 2 (EL) emits light when the light receiving circuit 8 detects light from the light.

FIG. 2 shows an electric circuit, and characters are displayed on the dial plate 3 of the license plate 2, for example, without transparency. Reference numeral 5 is an EL, 6 is a control circuit, and the control circuit 6 is driven by a signal from the light receiving circuit 8 to cause the EL 5 to emit light.
Reference numeral 7 is a holding frame.

The above is an example in which the license plate 2 is made to emit light. In the case of a truck parked on the road, a blinking light is attached to the rear portion of the vehicle body and the blinking light is controlled by the control circuit 6. However, the license plate 2 and this blinking light may be used together.

[0011]

As described above, according to the present invention, the license plate or the blinking light emits light upon receiving the light of another vehicle or the light of a flashlight. You can read the number without approaching. Therefore, it is effective in crime prevention and there is no fear of a rear-end collision. Especially in the case of large trucks, buses, etc., a blinking light is attached to the rear of the car so that it can be found quickly and may cause a serious accident by hitting a car parked on the street at night (prevention). Is extremely effective for
