DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention
The present invention relates to a device for preventing an accident in which another automobile, motorcycle, bicycle or the like collides with a parked or stopped truck or the like.

[0002]

2. Description of the Related Art In the nighttime, many rear-end collisions occur on vehicles that are parked or stopped with the parking / stop lamp turned off on the road. In particular, in the case of trucks, buses, and heavy equipment, there are many cases in which a large rear-end collision has occurred because of the large vehicle width and the small number of objects reflecting light from the rear. Therefore, it has recently become mandatory to attach a reflector to the rear of a heavy truck.

[0003]

However, the above-mentioned reflector has the following drawbacks, since it has a structure that only reflects light from the headlights of a car. a. Since the light is reflected only by the size of the reflector, it is difficult to distinguish whether this is a track or another object from a distance, and the detection (visual recognition) may be delayed. b. Reflectors are easily soiled, especially in the case of trucks that transport earth and sand, such as dump trucks. is there. c. It is not mandatory to attach a reflector to the side of the car, but there are many cases of side collisions with cars parked or parked at night. An object of the present invention is to propose a rear-end collision prevention device free from the disadvantages described in the above items a to c.

[0004]

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

In a rear-end collision prevention device including a day / night detection sensor, a vehicle detection sensor, and a light emitter, only when the conditions of the day / night detection sensor ON, the vehicle detection sensor ON, the engine key OFF, and the side brake ON are satisfied. and a power supply circuit is closed by providing a control circuit for light emitting the light emitting member formed <br/> Ru collision prevention device.

[0006]

[Action] At night, day and night detection sensor ON, car detection sensor ON, engine switch OFF, side brake ON
At this time, the luminous body emits light to call attention to the rear and side vehicles. In each of the above-described configurations, the type and color of the light-emitting body are not particularly limited, but it is optimal to use an LED that combines features of low power driving, high brightness, and small size. The power supply is
You may comprise so that an exclusive power supply may be provided other than the battery of a motor vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. 1
Reference numeral 0 denotes a main body of the apparatus, 11 denotes a red light emitting element (LED), 12 denotes a day / night detection sensor, 13 denotes a light detection sensor, and 14 denotes a control circuit. The light detection sensor 13 detects the light of the vehicle light, the engine key 15 is turned off, and the side brake 1
6 is ON, the power supply circuit of the red illuminant 11 powered by the battery of the automobile 17 is closed, and the red illuminant 11
To emit light. The device of the present invention is more effective when mounted on both sides of the rear portion of the vehicle 17 respectively. Next, when an automobile is detected by using signals such as radio waves, sound waves, and heat waves, respective transmitting and receiving circuits are provided on the device side, and when these signals are detected by the automobile, a red light is emitted. The body 11 will emit light. Alternatively, only the red or yellow illuminant and the vehicle detection sensor may be mounted on both sides of the vehicle and controlled by one control circuit 14. It is desirable that the flashing type of the luminous body 11 draws attention.
New In the figure, reference numeral 18 denotes a reflection plate.

The above embodiment is an example implemented only for the purpose of preventing rear-end collision. As shown in FIG. 1, a red light-emitting body 11 and a light detection sensor 13 are attached to the side of an automobile 17 to You may comprise so that detection of a vehicle from the side and collision prevention may be measured.

[0009]

The effects of the present invention are as follows. a. The rear-end collision prevention device detects the light of the headlights of cars, motorcycles, and bicycles at night, and the luminous body emits light immediately. b. By attaching the rear-end collision prevention device or the vehicle detection sensor and the light emitting body to both rear sides of the automobile, it is possible to reliably detect a motorcycle or bicycle traveling particularly on the sidewalk side and to notify the parking or stopping. c. Collisions of cars, motorcycles, bicycles, etc. from the side can also be prevented. d. Since the sensor is automatically operated only at night by the day / night detection sensor, there is no fear of forgetting to turn on or turn off the switch as in the case of a manual switch or the like. e. Engine key OFF, side brake ON
Only when the red illuminant emits light will the car
I know well from the following vehicle to be parked in, more exercise caution
Evoked.
