DEVICE FOR LANE INDICATOR}

The present invention relates to a lane marking device. More specifically, the present invention relates to a lane marking device, and more specifically, to enable the lane and vehicles traveling in front to be clearly visible even at night or in bad weather (fog, heavy snow, heavy rain, etc.) through an illumination film generated by a laser on the lane. Also, if the driver accidentally crosses into the next lane while driving, the light screen can be brightly displayed to make the driver aware that he or she is driving while leaving the lane, and the characteristics of the road and This relates to a lane marking device that can selectively change the shape of the lighting screen to a fan-shaped or straight shape, etc., depending on the situation.

Generally, luminous or reflective road signs are installed along with lanes on the road surface to ensure safe driving of vehicles, or lane indicators such as fog lights are installed on the roadside.

Lane marking spheres are mainly installed on the outside of the road or on the lane to mark the road or lane by absorbing and refracting the light emitted from the headlights of vehicles driving at night and emitting and reflecting the light. The marking sphere is formed in a trapezoid and the reflector is spread in all directions. By reflecting light from various angles, drivers in all lanes can always check the location of the indicator ball in all lanes, not just vehicles driving in one lane at night, thereby preventing accidents that violate the center line when changing lanes. will be.

These conventional lane markings were installed in a rectangular shape with reflectors combined only on both the front and back sides, so the lane markings could be seen only when the reflected light properly reached the driver.

Therefore, at night or in bad weather (fog, heavy rain, etc.) when it is difficult to see reflected light sufficiently, when a vehicle in another lane changes lanes, or when vehicles are congested due to a traffic accident ahead, they are unable to properly slow down or stop, resulting in a collision with the vehicle in front. There is a risk that it may lead to a major accident, and there is a problem that it is difficult to check the roadway or traffic conditions, especially on roads with severe fog.

In addition, in the case of mountain roads, curved roads, national highways, bridges, and local roads with poor driving conditions, drivers of vehicles traveling at high speeds cannot accurately recognize the lanes or curve angles of the road, causing them to deviate from their lanes, resulting in traffic accidents. It is becoming a cause.

The laser irradiation unit 10 displays the positions of the lanes L between the lanes L formed along the longitudinal direction of the road (vehicle traveling direction) or all lanes formed along the longitudinal direction of the road (vehicle traveling direction) ( At least one laser beam may be placed on L, and the drawing shows an example in which the laser irradiation unit 10 is placed on the lane L.

In addition, the laser irradiation unit 10 is disposed on all lanes (L) formed along the width direction of the road, allowing the driver to easily identify the positions of all lanes (L).

The laser irradiation unit 10 may include a laser pointer that generates a laser beam that is very strong in wavelength, phase, and intensity and is clearly irradiated to a long distance with little change in diameter.

At this time, the laser irradiation unit 10 may be embedded in the road surface at a certain depth.

The laser pointer 11, which irradiates a laser beam, is exposed to the road surface of the laser irradiation unit 10.

Accordingly, the laser pointer 11 of the laser irradiation unit 10 radiates a laser beam in the sky direction.

That is, the laser irradiation unit 10 generates a laser beam to accurately recognize the position of the lane L formed on the road to the driver.

In particular, the laser irradiation unit 10 irradiates a laser beam toward the sky on the lane (L). If the driver of the vehicle accidentally crosses into the next lane (L) while driving, the laser beam is brightly illuminated to the driver. It becomes visible.

Through this, the driver can be made aware of the fact that he or she is driving out of the lane (L).

Additionally, when the vehicle drives normally between the left lane (L) and the right lane (L) based on the width direction of the road, the laser beam appears blurred to the driver compared to when the vehicle deviates from the lane (L).

Through this, the driver can be made aware of the fact that he or she is driving normally without leaving the lane (L).

In addition, the laser irradiation unit 10 irradiates a laser beam, allowing the driver to more easily and reliably recognize the position of the lane L even in environments such as fog, night, heavy rain, or heavy snow.

The color of the laser beam may be any one of green, red, or a mixture of red and green.

At this time, it is desirable to set the color of the laser beam to green in order to protect the driver's eyesight and clearly recognize the lane (L).

In addition, it is revealed that the color of the laser beam can be formed in various colors as long as it is a color that can recognize a safe and clear lane (L).

Additionally, the laser irradiation unit 10 is selected from one of a type that can irradiate a laser beam in a straight line, a type that can irradiate a laser beam in a fan shape, and a type that can irradiate a laser beam in a trapezoidal shape. Can be applied to roads.

The laser irradiation unit 10 described above may include a battery.

The battery can be formed as a secondary battery that can be repeatedly charged and used.

And, the battery can be charged through a solar generator (G).

Solar power generators (G) can be installed on roads, medians, guardrails, etc.

The solar generator (G) is electrically connected to the battery.

The solar generator (G) generates electricity by converting the sun's light energy into electrical energy, the micro inverter boosts the DC voltage generated by the solar generator (G) and converts it to AC voltage, and the battery is converted into AC voltage by the micro inverter. The output AC voltage is charged.

Additionally, the lane marking device 1 according to an embodiment of the present invention may further include at least two transparent units 30 that are selectively mounted to be located in front of the laser pointer 11 of the laser irradiation unit 10. You can.

The transparent portions 30 may all be formed in a square box shape with an open bottom and an empty space inside.

Accordingly, the transmission unit 30 may be mounted to surround the upper outer peripheral surface of the laser irradiation unit 10. As a result, a certain area including the laser pointer 11 of the laser irradiation unit 10 is located in the internal space of the transmission unit 30.

For example, the transmission part 30 may be detachably coupled to the laser irradiation part 10 through a bolt or piece.

As another example, the first magnet 2 may be embedded in at least two of the four inner surfaces of the transmission part 30, and the first magnet 2 may be embedded in the outer surface of the corresponding laser irradiation part 10. A second magnet 3 formed to have an opposite polarity and attached to the first magnet 2 may be installed.

Accordingly, the transmission portion 30 can be easily coupled to or separated from the laser irradiation portion 10 through bolts, pieces, or the first magnet 2 and the second magnet 3.

In particular, a viewing window 31 formed in different patterns or shapes is formed on the upper side of each transparent part 30.

At this time, the upper surface of the transparent portion 30 may be formed of a non-transparent material or a tempered glass material.

When the upper surface of the transmission portion 30 is made of tempered glass, a non-transparent film may be attached to the tempered glass to prevent the laser beam from being emitted toward the sky through the tempered glass. Because of this, the laser beam is irradiated toward the sky only through the viewing window 31.

Subsequently, the viewing window 31 may be made of tempered glass to prevent it from being damaged by the load of the vehicle.

The viewing window 31 converts the laser beam of the laser irradiation unit 10 into a certain form and irradiates it toward the sky.

Specifically, the viewing window 31 formed in one of the transparent portions 30 may be formed in a curved shape.

The laser beam can be radiated over a wide range through the curved viewing window 31.

In this way, when the viewing window 31 is formed in a curved shape, the irradiation range of the laser beam can be expanded. In other words, a kind of illumination film can be formed in the lane (L) through the laser irradiation unit 10. The laser beam can be irradiated broadly in a fan shape through the curved viewing window 31, so that the driver can see the lane (L). It can tell the location more clearly and reliably. This ensures safe driving by preventing vehicle-to-vehicle collisions, collisions, or vehicles from colliding with road structures such as guardrails and streetlights even in environments such as fog, night, heavy rain, or heavy snow, and also protects the precious lives of drivers. can do.

Additionally, the viewing windows 31 of other transparent parts 30 may be formed in various shapes, such as a straight shape or a circular shape.

In other words, the transmission unit 30 corresponding to the road conditions and environment can be selected and mounted on the laser irradiation unit 10.

A through hole 30a is formed in the transparent part 30 so that the illuminance sensor 20 measures the amount of surrounding light.

Meanwhile, the illuminance sensor 20 is coupled to one side of the laser irradiation unit 10.

The illuminance sensor 20 adjusts the brightness of the laser beam emitted from the laser irradiation unit 10 depending on the amount of surrounding light, or turns the operation of the laser irradiation unit 10 on or off to save battery power.

The illuminance sensor 20 measures the ambient light in real time and transmits it to the control unit 60, and the control unit 60 determines whether the amount of ambient light measured by the illuminance sensor 20 corresponds to daytime or, even if it is daytime, rain, If visibility is deemed to be poor due to fog, fine dust, yellow dust, nighttime, or heavy snow, the brightness of the laser beam is adjusted to be brighter than the preset standard value. If it is night or dark, the brightness of the laser beam is adjusted to be dimmer than the preset standard value. Control to save battery power.

In addition, when the amount of ambient light measured by the illuminance sensor 20 corresponds to daytime hours, the control unit 60 turns off the operation of the laser irradiation unit 10 by cutting off the power applied to the laser irradiation unit 10 from the battery. It can also be programmed to do so.

Additionally, the lane marking device 1 according to an embodiment of the present invention can be used together with the illuminance sensor 20 by storing a clock program for distinguishing between day and night.

Furthermore, the laser irradiation unit 10 may receive a control signal for adjusting the operating time and brightness of the laser beam from the control unit 60 using wireless communication.

Wireless communication may be configured to transmit and receive data using a wireless communication network or a LoRa communication network.

The control unit 60 can be programmed into an administrator's PC or an administrator's wireless terminal.

Accordingly, the manager can control the on/off of the laser irradiation unit 10 or selectively control the brightness of the laser beam through the manager's PC or the manager's wireless terminal according to the illumination of the road.

Meanwhile, the module unit 40 is configured to modularize a plurality of laser irradiation units 10 by a certain number.

The housing 41 may be formed in a rectangular box shape with an open top and an empty space inside.

At this time, the housing 41 may have a length shorter than or equal to the length of the lane L.

The upper open portion of the housing 41 is sealed by a cover 411.

A plurality of exposure holes 411a exposing the laser pointer 11 or the transmission portion 30 of the laser irradiation portion 10 are formed in the cover 411 at the same intervals as the laser irradiation portion 10.

At this time, the exposure hole 411a is formed to have a certain length to expand the irradiation range of the laser beam.

Also, it may be installed in the exposure hole 411a of the cover 411 instead.

The transparent window may be made of tempered glass.

The cover 411 may be made of a material that is not damaged by the load of the vehicle, and for example, may be made of tempered glass.

A lane L is painted on the upper surface of the cover 411. In addition, since a plurality of laser irradiation units 10 are installed in the inner space of one housing 41, the laser pointers 11 or transmission units 30 of the laser irradiation units 10 are arranged at regular intervals on the lane L. It can be.

The partition portions 42 are composed of two pairs and are arranged at regular intervals in the inner space of the housing 41 to position the laser irradiation portion 10 in the partitioned space.

Both sides of the partition 42 may be coupled to one inner wall and the other inner wall of the housing 41, respectively.

The partition 42 may be made of a metal material with excellent rigidity so as not to be deformed by the load of the vehicle.

The support wall 43 may be made of mortar, and each space between the pair of partitions 42 is filled and cured to form a wall.

The support wall 43 is disposed between the pair of partitions 42 and is disposed at regular intervals in the inner space of the housing 41 to support the vehicle load transmitted from the cover 411 to the housing 41. ) to prevent bending, deformation, or damage. Through this support wall 43, the housing 41 can be safely protected from the load of the vehicle.

Meanwhile, the moving part 50 is installed inside the module part 40, and adjusts the position of the laser irradiation unit 10 along the lane (L) direction to vary the irradiation range of the laser beam irradiated from the laser irradiation unit 10. It is a configuration that changes repeatedly.

To this end, the moving part 50 may include at least one of a slide part 51, a striking part 52, and an elastic support part 53.

The slide unit 51 has a box or barrel structure with an open top and an empty space inside, and is mounted to surround the lower peripheral surface of the laser irradiation unit 10.

The slide part 51 is seated on the bottom surface of the housing 41.

A slide protrusion 511 that slides in both directions along the rail groove 41a formed along the longitudinal direction of the central bottom surface of the housing 41 is formed on the bottom of the slide portion 51.

Because of this, the laser irradiation unit 10 and the slide unit 51 can be moved in both directions along the longitudinal direction of the lane L.

At this time, the slide part 51 slides with its bottom seated on the bottom surface of the housing 41.

The striking unit 52 is a component that strikes one side of the slide unit 51 at preset time intervals and may be formed of a known solenoid.

Specifically, a striking ball 521 that strikes one side of the slide unit 51 is coupled to one side of the striking unit 52.

The hitting ball 521 may be made of rubber or silicone to minimize impact force and noise applied when hitting the slide unit 51.

The striking units 52 are respectively disposed in partition spaces of the housing 41 partitioned by the partition units 42 and strike the slide units 51 through the striking balls 521, respectively. At this time, the hitting portion 52 may be fixed to the bottom surface of the housing 41.

The hitting unit 52 may include a battery.

The battery can be formed as a secondary battery that can be repeatedly charged and used.

The battery of the hitting unit 52 can also be charged through the solar generator (G) described above.

The control unit 60 may include a program that controls the operation of the striking unit 52.

Accordingly, the operation of the striking unit 52 can be remotely controlled through the above-described administrator PC or administrator wireless terminal.

The elastic support portions 53 are disposed in each partition space of the housing 41 and are configured to push the slide portion 51 struck by the striking portion 52 toward the striking portion 52 .

To this end, the elastic support portion 53 may include at least one of a push plate 531 and a spring 532.

The push plate 531 is disposed at a predetermined distance from the other side of the slide unit 51.

The push plate 531 is against the other side of the slide unit 51, and may be made of rubber or silicone to minimize impact force and noise.

The spring 532 elastically supports the push plate 531 with one side fixed to the partition 42.

The spring 532 may be formed of a coil spring or a leaf spring, and the drawing shows an example formed of a coil spring.

Next, the operation and effects of the moving part 50 described above will be described.

When power is supplied to the hitting unit 52 through the manager's PC or the manager's wireless terminal, the hitting unit 52 moves the hitting ball 521 forward and backward.

The hitting ball 521 hits one side of the slide unit 51 in the forward and backward process and then moves backward and returns to its original position.

Accordingly, the slide protrusion 511 moves along the rail groove 41a, and the slide part 51 moves along the bottom surface of the housing 41, and the laser irradiation part 10 also moves along the slide part 51. move

Then, the slide part 51 moves and collides with the push plate 531, and the spring 532 is compressed and expanded, causing the push plate 531 to move the slide part 51 again in the direction of the hitting ball 521. push it out

Additionally, the hitting unit 52 is programmed to advance the hitting ball 521 when the slide unit 51 is pushed by the push plate 531 and returned to its original position.

For example, if the time for the slide unit 51 to collide with the push plate 531 and then return to its original position is 5 seconds, the hitting unit 52 moves the hitting ball 521 forward and backward at 5 second intervals. It is programmed to do so.

Because of this, the laser irradiation unit 10 moves repeatedly in both directions at the lower side of the exposure hole 411a and irradiates a laser beam in the direction of the sky.

As a result, the laser beam moves on the lane (L) and is radiated toward the sky. Ultimately, by increasing the irradiation range of the laser beam, a more stable driving environment can be provided to the driver.

At this time, the manager can operate the striking unit 52 in situations where it is necessary to alert the driver, such as during times when there is a lot of vehicle traffic or when visibility is poor due to rain, fog, fine dust, yellow dust, night, or heavy snow.
