Description

  The present invention relates to an emergency stop display device that informs a subsequent vehicle when a vehicle is urgently stopped or when the vehicle is urgently stopped.

  Once an accident occurs on a highway, it often leads to a serious accident. And it is said that the accident on the highway is a rear-end collision with a car that is almost stopped. For this reason, a technique has been proposed in which a so-called triangular stop display plate is caused to emit light so as to notify the following vehicle that the vehicle is stopped (Patent Document 1). In order to prevent the following vehicle from colliding at the time of braking, a brake lamp has been proposed that informs the subsequent vehicle of sudden braking (Patent Document 2).

Noto 3132463 Publication JP 2006-248294 A

However, in the technique of Patent Document 1, the triangular stop display plate must be installed outside the vehicle after the vehicle is stopped, and an accident at the time of braking or immediately after the stop cannot be prevented. Moreover, in the technique of patent document 2, when the front is congested and it stops, it cannot be made to function, since a sudden brake is not applied.
The present invention has been made in view of such circumstances, and provides an emergency stop display device that informs a subsequent vehicle when a vehicle is stopped urgently or when the vehicle is urgently stopped. The purpose is to do.

  In order to solve the above-mentioned problem, the present invention is installed on the rear surface of a vehicle, and when this vehicle is to be stopped urgently, or when the vehicle is actually urgently stopped, this is followed. An emergency stop display device for informing a driver of a car, comprising: a first light source; a character display board on which a warning character is displayed when the first light source emits light; and the warning A plurality of second light sources provided to enclose characters, control means for independently turning on and off the first light source and the second light source, and connected to the control means and installed in the driver's seat And an operation switch.

  ADVANTAGE OF THE INVENTION According to this invention, a vehicle can be stopped urgently or it can notify a following vehicle that the vehicle has stopped urgently.

It is explanatory drawing which showed the structure of the emergency stop display apparatus.

  Hereinafter, embodiments embodying an emergency stop display device according to the present invention will be described with reference to the drawings.

  First, the configuration of the emergency stop display device 1 according to the embodiment will be described with reference to FIG. FIG. 1 is an explanatory diagram showing the configuration of the emergency stop display device 1. In FIG. 1, only one of the plurality of the first light source 12 and the second light source 13 is assigned with a reference numeral in order to make the drawing easier to see.

  The emergency stop display device 1 mainly includes a character display board 11, a first light source 12, a second light source 13, a lamp control board 14 (corresponding to control means in claims), and an operation switch 15.

  The character display plate 11 is a translucent resin plate in which the character portion is milky white and the other portions are red. The letters are “emergency stop” to call attention. A plurality (16 in this embodiment) of the first light sources 12 are disposed on the back side of the character display board. The first light source is an LED bulb. The character display board 11 emits and displays characters by irradiating light from the first light source 12 from the back side.

  In the present embodiment, such a configuration is used. However, the first light source may be a dot type to display characters, or the character portion of the character display board may be configured to transmit only a specific color. Any configuration may be used as long as the first light source emits light so that characters are displayed, such as a full-color LED.

  The character display board 11 is a horizontally long rectangle in front view. In the present embodiment, a horizontally long rectangle is used, but a vertically long rectangle may be used. If there is no problem in character visibility, the shape is not limited.

  A plurality (24 in this embodiment) of second light sources are provided so as to surround the characters displayed on the character display board 11. The second light source is also an LED bulb.

  The lamp control board 14 can turn on and off the first light source 12 and the second light source 13 independently. This mechanism uses a well-known technique. The lamp control board 14 is connected to a battery of the vehicle (not shown) via a power line (not shown).

  The first light source 12, the second light source 13, and the lamp control board 14 are accommodated in a waterproof main body case 16, and the character display plate 11 covers the main body case 16. The main body case 16 is installed on the rear surface of the vehicle.

  The operation switch 15 is connected to the lamp control board 14 via a signal line and is installed in the driver's seat. The operation switch 15 is a so-called alternate operation switch that is turned on when pressed once and turned off when pressed again (in FIG. 1, the detailed shape and the like are omitted). The operation switch 15 incorporates a lamp (not shown) so that the position can be grasped even at night. In addition, the lamp brightness increases and blinks in the ON state so that it can be determined whether it is in the ON state or the OFF state.

  The driver turns on the operation switch 15 when he / she determines that the vehicle must be stopped urgently and there is a risk of being collided with the following vehicle. Then, the first light source 12 and the second light source 13 are turned on and off in conjunction with each other.

Specifically, first, the first light source 12 is turned on for 0.5 seconds and then turned off. At the same time as the first light source 12 is turned off, the second light source 13 is turned on and turned off after 0.5 seconds. Then, the first light source 12 is turned on again at the same time as the second light source 13 is turned off and turned off after 0.5 seconds, and the second light source 13 is turned on at the same time as the first light source 12 is turned off. Turns off after 5 seconds.
Thereafter, at the same time as the second light source 13 is turned off, the first light source 12 is turned on and turned off after 2 seconds. While the first light source 12 is on, the second light source 13 repeats blinking at intervals of 0.2 seconds.
This is repeated as one cycle. As a result, the driver of the succeeding vehicle can recognize that the vehicle is in an emergency stop.

  Further, if the operation switch 15 is turned on even after the vehicle has stopped, it is possible to notify the driver of the following vehicle that the vehicle has stopped urgently.

  In addition, although it was set as such a structure in this embodiment, of course, it does not restrict to this about the timing of lighting of 1st light source 12 and 2nd light source 13, and extinction. In addition, the timing of turning on and off the first light source 12 and the second light source 13 may or may not be interlocked as in the present embodiment.

When an emergency stop is performed, the hazard lamp is blinked. However, the blinking speed of the hazard lamp is the same as the blinking speed of the blinker, and if the driver of the following vehicle is tired, it may be slow to notice. In addition, during road construction, red, yellow, dark blue, green and colorful lights that flash on the road are often mixed with other lights, so the hazard lamps flash. It may be inconspicuous because it blends into these lights.
Therefore, when the first light source and the second light source are caused to blink, it is desirable that the blinking speed of the blinker is different from that of the blinker. It is desirable to set the color and blinking speed.

  The contents described above relate to an embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
