Description

Intelligent safety signs for cars {INTELLIGENT WARNING TRIANGLES}

The present invention relates to an intelligent safety sign for an automobile. More specifically, the present invention relates to the presence of a rear approach vehicle in a safety sign that allows a driver of a vehicle approaching from behind to decelerate on a road or repair a road. It is possible to expect efficient utilization of luminous power by flashing various warning messages in various ways by sensing the vehicle's field of view approaching within a certain distance, and compared to the conventional reflective safety signs, the driver of a rear-access vehicle is more concerned with the surrounding conditions and situation The present invention relates to an intelligent safety sign for automobiles, which can easily recognize the situation of the stopped vehicle without preventing accidents on the road.

In general, when a vehicle is driving on a road and a problem occurs in the engine, power train, or wheels, driving becomes impossible, the driver immediately installs a tripod, which is an emergency safety sign, at a certain distance behind the stopped vehicle. It is customary to let your car know that your differential is stationary and to call or to service your tow vehicle quickly.

The dragon leg 12 is formed to protrude downward, and the support 13 extending downward in the rear center portion is rotatably coupled.

However, the tripod for safety signs according to the prior art has a visible distance of only 300 meters by attaching a reflector to the tripod and is configured to reflect only when there is a light source from the outside. The situation is frequently occurring.

That is, by simply reflecting the headlights of the vehicle traveling behind the car from safety signs to inform the rear vehicle of the stationary vehicle, the headlights of the rear vehicle in case of rain, snow or fog depending on the surrounding climatic conditions. There is a problem that the rear vehicle can not detect the light can not reflect the light and the installation position of the safety sign tripod is low so that it does not enter the rear vehicle driver's view.

Therefore, in recent years, a safety tripod has been provided so that the safety tripod can be self-illuminated by a battery by installing an LED inside the safety tripod, so that it can be easily distinguished even at a long distance or a curved section at night. Safety tripods are only used when needed and this need arises after a considerable time has elapsed or when the need for a safety tripod decreases due to the discharge of the battery. It happens.

The present invention has been made to solve the above problems, the purpose of which is the presence of a rear access vehicle in a safety sign that allows the driver of the vehicle approaching from the rear when the vehicle breakdown or road maintenance work on the road to decelerate By detecting whether the vehicle is approaching within a certain distance and flashing various warning messages in various ways, it is possible to expect efficient utilization of luminous power. It is to provide a safety sign for automobiles to make it easier to recognize the situation of the vehicle.

The intelligent safety signs for automobiles to which the present invention is applied are detected by the presence of a rear approach vehicle, and when the vehicle approaches a predetermined distance or more, the tripod 10 flashing the warning letter to the outside and the tripod 10 are outside the vehicle at a predetermined height or more. It is configured to include a support 20 for supporting to be exposed to.

Referring to Figure 2 and 3 in more detail with respect to the intelligent safety signs for automobiles according to an embodiment of the present invention,

The tripod 10 has a hollow inner space and the outer frame is composed of a case 11 composed of three frames in which a transparent plate is attached in a front direction and is assembled in a triangular shape. In the following will be accommodated for the power supply function, the approach vehicle detection function, the rotary blinking function of the warning character.

At this time, the transparent plate exposed to the front from the case 11 of the tripod 10 is partially opaque to the light emitted inside the case 11 so as to opaque to reveal the warning letter to the outside The warning letter is formed of a plate of the warning letter, and the warning letter may be formed in various forms in each of three frames as shown in FIG. 3, and in the present invention, the warning letter is necessarily as shown in the drawings. Not only Korean or English characters, but also various symbols, figures, and patterns may be made.

The case 11 of such a tripod 10 is preferably composed of a plastic of a common acrylic material, the three frames constituting the tripod 10 is made of a connecting port is a conventional fastener and a power transmission connector user It can be easily disassembled and assembled.

On the other hand, the support 20 is shown in Figures 2 and 3 for positioning the tripod 10 is raised to a predetermined height from the ground,

The support 20 is coupled to the tripod 10 at the hinge portion 21 of the upper side to support it, and the external exposure angle of the tripod 10 can be freely adjusted in conjunction with the rotation of the hinge portion 21. do. In addition, the support 20 is stably made of a flexible structure that can be changed in height so as to freely adjust the external exposure height of the tripod 10 through the elastic member 22 of the lower side.

Accordingly, FIGS. 2 and 3 show a support 20 in which three legs are positioned close to the hinge portion 21 in a camera pedestal type based on stability to an external environment such as wind, and FIG. 4. The microphone stand type based on mobility and storage is shown a support 20 in which three legs are positioned at a predetermined distance apart from the hinge portion 21, so that the support of the tripod 10 supported by each elastic member 22 is shown. The exposure height can be freely determined.

At this time, the height of the support 20 corresponds to a height of at least 1 m from the ground to overcome the disadvantage that the reflective safety signs of the conventional method is not 50 cm away from the ground when the actual installation is not properly exposed to the vehicle driver approaching from the rear. It is preferable that it can be stretched to expose the tripod 10.

On the other hand, inside the case 11 of the tripod 10, the operation switch 12, the control unit 13, the battery 14 which is a component for the power supply function, the approach vehicle detection function, the rotary flashing function of the warning character described above. ), The charging unit 15, the vehicle detection unit 16, the detection switch 17, the light emitting means 18, and the sound output unit 19 are built in. Hereinafter, the intelligent operation of the tripod 10 will be described with reference to FIG. 5. Look at the message blinking feature.

The operation switch 12 is located on the case 11 of the tripod 10, and is a preliminary start switch for preparing a message blinking function of the tripod 10 in accordance with the user's selection.

That is, when the operation switch 12 is turned on, the vehicle detection unit 16 starts operation. The vehicle detection unit 16 typically reflects the light emitted from the laser beam having good straightness and the emitted light. And the light emitted from the light emitter, that is, the light emitted toward the rear of the stopped vehicle is reflected by the approaching vehicle from the rear and approaches the receiver by using the time difference reaching the light receiver. Calculate the distance.

In this case, the vehicle that the vehicle detecting unit 16 recognizes may be not only a general vehicle but also driving devices such as a tiller, a tractor, a motorcycle, and a bicycle.

Therefore, the vehicle detecting unit 16 turns on the sensing switch 16 when the vehicle approaching from the rear is within a predetermined distance (for example, 500 m rear of the safety sign installation position), thereby driving the driving power of the battery 14 to the control unit ( 13) so that the corresponding driving power is transmitted to the light emitting means 18 and the sound output unit 19 so that the actual warning message flashing function of the corresponding tripod 10 and the driver of the accident vehicle as a warning sound. Enable alarm function.

That is, the driver of the vehicle stopped on the road is located at a distance from the accident vehicle so that the safety sign of the present invention to the rear from the rear of the vehicle facing a predetermined distance and turn on the operation switch 12 to the vehicle detection unit 16 When the approach vehicle detection function of) is started and the vehicle detection unit 16 detects the approaching vehicle within a predetermined distance, the detection switch 17 is turned on so that the power of the internal battery 14 is transferred through the control unit 13. It is to be transmitted to the light emitting means 18 and the sound output unit 19.

At this time, the sound output unit 19 performs a function of outputting a predetermined warning sound indicating the approach of the vehicle from the rear to the accident vehicle side of the stop state, the light emitting means 18 for the approach vehicle approaching the accident vehicle In order to perform the warning function, the sound output unit 19 is directed toward the rear of the tripod 10, ie toward the accident vehicle, unlike the light emitted from the front of the tripod 10, ie, toward the rear of the accident vehicle. It is preferably located on the rear side of the tripod 10 to output a predetermined warning sound.

In addition, the control unit 13 is programmed with a predetermined operation algorithm such that each of the light emitting means 18 individually configured in three frames can blink at the same time or at a time difference. One or two of the light emitting means 18 are turned on and the other light emitting means 18 flashes in a rotational manner in which the turning off operation is performed continuously, thereby making it possible to visually compare the light reflection operation or the simple light emitting function in the conventional safety tripod. This makes it possible to reliably recognize warning messages to rear approach vehicles.

The warning characters respectively formed in the case 11 are exposed to the outside by the rotation flashing operation by the internal light emitting means 18 that emits light according to the flashing control of the controller 13. They can solve the problem of limiting the recognition distance of the conventional reflective tripod or LED emitting tripod by using the low-power, high-efficiency strobe light that can be visually recognized by the vehicle driver even at a distance of more than 1 km. .

On the other hand, the battery 14 for supplying the power required for such a rotary flashing operation can be configured as an independent power source (for example, 8 AA 1.5 Volt batteries) to be mounted directly to the mobile battery, or configured as a rechargeable battery DC power (12 Volt) is supplied from the cigar jack of the through the charging unit 15 can be used as a charging method, it is also possible to directly receive and use the DC power through the shisa jack of the vehicle.

The present invention described above is possible to those skilled in the art to which the present invention belongs, various substitutions, modifications and changes can be made within the scope without departing from the spirit of the present invention and the above-described embodiments and attached It is not limited to drawing.

As described above, the intelligent safety signs for automobiles shown in the present invention have a safety sign that allows a driver of a vehicle approaching from behind to decelerate on a road or a road maintenance work to decelerate a rear approach vehicle within a predetermined distance. By detecting the approaching vehicle and recognizing various warning messages in various ways such as rotation and flashing by the visual field of the approaching vehicle, it is possible to emit light for a longer period of time by efficiently utilizing the luminous power of safety signs due to the nature of the vehicle trouble that cannot be resolved. At the same time, compared to the conventional reflective safety signs, it is possible to more clearly recognize the situation to the driver of the rear vehicle regardless of the surrounding conditions and circumstances, thereby preventing safety accidents on the road.

Fixed and lowered tripod height of the existing reflective type was not able to be grasped properly by the approaching vehicle from the curved rear, and it is possible to freely adjust the separation distance of the ground and tripod through the extension member of the support, at least 1m The vehicle is exposed rearward at the height of the vehicle to facilitate recognition of the rearward approaching vehicle, thereby significantly preventing a collision accident caused by a subsequent vehicle.

By adopting Strobe Light for observation and recognition from a distance of 1km from the front of the tripod, the rear approach vehicle can recognize the vehicle situation ahead from a long distance calmly regardless of the weather situation. At the same time, the power for the corresponding light emitting function can be supplied by itself (cigar jack), so that it can be used stably without the effect of low battery or discharge.

When the approaching vehicle is detected, not only the flashing warning for the approaching vehicle but also a predetermined warning sound is generated on the side of the accident vehicle, and the presence of the approach vehicle also occurs on the side of the accident vehicle due to the nature of the tripod installed at a predetermined distance from the accident vehicle. In addition, the accident vehicle side is also effective in preparing for accidental safety accidents.
