Abstract

(57) [Abstract] [Purpose] The present invention relates to a vehicle rear-end collision prevention device,
An object of the present invention is to prevent the danger of a rear-end collision by moving a light beam reflected from a headlight of a following vehicle so that the light beam can be noticed early by the movement to promote a brake operation. [Structure] Upper and lower rollers are arranged at the rear of the truck, a belt rotated by a motor is provided between the upper and lower rollers, and reflectors are attached to the belt at predetermined intervals.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is provided at the rear of a truck and reflects the headlights of the following vehicle to inform the following vehicle that this truck is parked or is running and to prevent a rear-end collision of the following vehicle. The present invention relates to a rear-end collision prevention device.

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, in a truck or other traveling vehicle, a reflecting device for reflecting the headlight of the following vehicle, generally a reflection device, is used to inform the following vehicle that the vehicle is parked or is traveling, especially at night. Plates or plastics that shine upon receiving light are provided.

However, in order to make it easy for a following vehicle to see, a reflector provided on a large truck has a reflector of 1 to 1.2 m at a relatively high place, that is, at a position of 0.65 m in a general vehicle. It is provided in the position.

[0004]

[Problems to be solved by the device]

 However, in large trucks, the vehicle body is large and the reflector is installed at a high position, so vehicles approaching from the rear will stop farther than the actual distance from the truck. It is easy to illusion that you are doing.

Therefore, in a place where the vehicle speed is high, such as on an expressway, the number of accidents in which a succeeding vehicle collides with a stopped truck is increasing, and as a countermeasure against this, as shown in FIG. The tail light 11 and the brake light 12 are separately provided at a low position comparable to a general vehicle, and the emission plate 13 is provided at a height of 45 cm at the rear part of the vehicle separately from the tail light 11 and the brake light 12. Is published in the April 26, 1990 issue of the Nikkan Jidosha Shimbun, and in the figure, reference numeral 14 indicates a direction indicator, and 15 indicates a side light.

However, only by such measures on the truck side, when the stopped truck is parked with the taillight turned off, the reflection device of the truck stopped by the headlight of the following vehicle is installed. By recognizing the reflection, the following vehicle knows that the truck has stopped.

In order for this reflecting device to sufficiently reflect, the headlight of the following vehicle is properly illuminated and then, while the vehicle is traveling, the headlight may travel downward. Because of the large number, there are delays in noticing the reflection of this reflection device, and the brake may not be in time.

In view of such a situation, the present invention moves the reflected light beam so that even if sufficient reflection is not obtained, the reflection is noticed so as to prompt the brake operation and reduce the risk of a rear-end collision. The purpose is to prevent.

[0009]

[Means for Solving the Problems]

 According to the present invention, upper and lower rollers are arranged at the vehicle rear part of a truck, a belt which is rotated by a motor is provided between the upper and lower rollers, and reflectors are attached to the belt at predetermined intervals. It is characterized in that upper and lower rollers are arranged, a belt rotated by a motor is provided between the upper and lower rollers, a reflecting plate is arranged inside the belt, and window holes are formed at predetermined intervals in the belt.

[0010]

[Action]

 In the truck rear-end collision prevention device of the present invention, when the belt is rotated by the motor, the reflected light is moved by the movement of the reflecting plate, and when the belt is rotated so as to move from the upper side to the lower side, the inner reflection is generated. The light reflected by the plate looks like moving through the window of the belt, and the moving light is easy for the eyes to sense, and the movement of this light is felt as if the truck is approaching from a distance. You can call attention to the car.

[0011]

【Example】

 Next, a first embodiment of the present invention will be described below with reference to FIGS. In this embodiment, two rollers 2 and 3 are installed substantially parallel to each other near the lower side of the vehicle body of the rear portion 1 of the truck and on both upper and right sides thereof, and the motor 4 is attached to one roller 2. Connect and allow it to rotate.

A black belt 5 is installed between the left and right rollers 2 and 3, and the belt 5 is rotated in the direction of the arrow in FIG. 1 by the rotation of the motor 4. A plurality of elongated red reflectors 6 are attached in parallel in the longitudinal direction of the belt 5 at appropriate intervals.

Then, if the switch of the motor 4 is attached to the driver's cab of the truck and the switch is turned on during traveling at night or during parking, the belt 5 is driven in the direction of the arrow and the reflecting plate 6 Moves from top to bottom.

Therefore, the reflected light of the headlight of the following vehicle moves from the top to the bottom, so that the eyes are sensitive to the moving light and the movement is as if the distance between the truck and its own vehicle. Appears to approach, and the braking operation is performed in accordance with this, which can prevent a rear-end collision accident of a following vehicle.

In another embodiment shown in FIGS. 3 and 4, instead of attaching a plurality of reflection plates 6 to the belt 5 of the above embodiment, a belt hole 5 having the same shape as the reflection plate 6 is formed in the belt 5. The large reflecting plate 8 is installed on the back side of the belt 5.

Accordingly, when the belt 5 is driven in the same manner as in the previous embodiment, the reflection of the headlight of the following vehicle is performed only through this window hole 7 and is not reflected by the belt 5, so that the belt of the previous embodiment is not reflected. Similar to the movement of the reflector 6, the reflected light rays move from top to bottom, and this visual sense prevents the rear-end collision accident as described above.

[0017]

[Effect of the device]

 As described above, according to the present invention, the reflected light of the headlight of the following vehicle moves from top to bottom or from bottom to top, so that the reflected light is easier to see than stationary light. It is easy to notice this early, and the probability of overlooking a truck traveling in front of the vehicle or parking will be reduced.

The movement of the reflected light rays, especially from the top to the bottom, is felt as if the distance between the vehicles is approaching. Therefore, the braking operation is promoted, and these are combined, so that there is a risk of a rear-end collision of the vehicles. The probability of avoidance is high.
