The present invention relates to a road sign bottle, and more particularly, to a road sign bottle that can flash automatically in rainy weather.

In general, the most fatal and the largest type of traffic accidents are the accidents caused by the central line, and most of the other types of traffic accidents are caused by lane violations. This is because car traffic runs in line with lanes and keeps the center line between them.

However, the number of accidents caused by invading the center line of roads and the lanes such as yellow mark line, double yellow line, middle dividing line, roadside line and limit line are increasing every year. As it accounts for 17.5%, most accidents caused by lane violations resulted in deaths.

In order to prevent accidental overtaking, speeding, or drowsy driving, such as illegal overtaking, speeding, or drowsy driving, safety facilities such as a median separator are installed to prevent accidents. Safety facilities such as road markers, gull marks, and eye-guided rods were installed in the lanes to prevent inattention.

Among these safety facilities, road marker bottles, which are intended to supplement visibility, are installed on the center line, edges, and branch lines of the road surface so that the roads and lanes can be clearly recognized by the driver at night, so that the direction of the vehicle's attention is clearly indicated. At the same time, the driver's attention is alerted and traffic accidents caused by the intrusion of the centerline of the vehicle or invasion zone are prevented due to the reflection of the reflector by the headlight of the vehicle. . In addition, the road sign bottle is used as an aid for location guide road marking that conveys the meaning of warning to the driver through the effect of visibility and contact with the automobile tire.

Road markers with the above functions are manufactured in various forms to separate lanes such as general roads, mountain roads, military roads, and outer roads, such as road center lines, lane boundary lines, roadblocks, road edges, zone lines, and dedicated roads. Lanes, safety zones, etc. A plurality of vehicles are installed at regular intervals along the lanes for night identification of the displayed lanes, thereby preventing traffic accidents that may occur during night driving or in the rain.

The case 110 is formed in a hole to be coupled to the upper to form a groove (112a) that can collect rain, it is preferably formed in a semi-spherical or rhombus hexahedron shape, so as not to hinder the running of the vehicle as a whole. The main body 120 is positioned at the lower portion of the case 110 to be coupled to the case 110 so as to be fixed on the road, and a fastening groove and a fastening portion are coupled to the case 110 and the main body 120 so as to be combined with each other. A shape such as a hook is provided. In addition, the rain water is coupled to the waterproof ring (not shown) and the like so as not to flow into the case (110).

The case 110 is positioned with a reflector 130 which brightens the center line and the surroundings of the lane by receiving the light of the traveling vehicle. The reflector 130 may be symmetrically located on the case, or may be coupled to both sides of the quadrangular shape. The case 110 has an irradiation mirror 135 coupled to the light emitted from the light emitting device 160 to the outside, the irradiation mirror 135 may be made of a transparent window or a semi-transparent window. By configuring the reflective plate 130 as a transparent window or a semi-transparent window, it is possible to irradiate the light flashing from the light emitting device 160 to the outside, it is also possible to reflect the light shining from the headlights of the vehicle.

The case 110 is provided with a hole 112a on an upper surface thereof, and is equipped with a cylindrical cap 114 whose diameter decreases from the top to the bottom so as to be joined to the hole 112a, and the rainwater collected in the cap 114 is the case. The waterproof cover 115 is mounted to be in close contact with the lower side of the cap 114 in order to prevent the flow into the 110. In addition, at least one photovoltaic panel 150 is installed on the upper surface of the case 110 to absorb solar energy during the day, and convert it into electrical energy to charge the photovoltaic cell 170 as a power supply. Will be. Therefore, during the daytime, the solar cell is charged with electrical energy using solar energy to supply power to the light emitting device 160 flickering in rainy weather, and rain or

rain sensors

141a and 141b which will be described later when it rains during the day or at night. As a result, the solar cell supplies power to the light emitting device to emit light.

The main body 120 may be coupled to the case 110 by a fastening means or a hook, or the like, and a waterproof ring may be coupled between the case 110 and the main body so that rainwater does not flow in. In addition, the lower surface of the main body 120, the anchor shaft 125 is formed to protrude in the downward direction and serves to fix the center line of the road.

The light emitting device 160 is embedded inside the case 110, and it is preferable to use a light emitting diode (LED) having high brightness as well as low power consumption. Therefore, the circuit board 180 is provided to mount the light emitting device 160, the upper light emitting device 160 of the circuit board 180 may be provided, and the solar cell 170 may be mounted.

Rain water sensor is provided between the solar cell 170 and the light emitting device 160 is connected to the switch unit (141a, 141b) for supplying the power of the solar cell 170 to the light emitting device 160 in accordance with the inflow of rain water It consists of. The

connection switch units

141a and 141b may be constituted by a pair of shorted

metal terminals

141a and 141b. The pair of

metal terminals

141a and 141b may be fixed to the circuit board 180, respectively. It is installed to be mounted on the waterproof member 115 so as to penetrate the waterproof member 115 and exposed to the inner bottom surface of the cap 114.

4A and 4B are side cross-sectional views illustrating an embodiment of a rainwater sensor applied to a vehicle light emitting device according to the present invention.

An embodiment of the rainwater sensor may be composed of only a pair of

metal terminals

141a and 141b shorted as shown in FIG. 4A. At this time, the cap 114 is seated on a flat portion of the waterproof member 115, and a pair of shorted

metal terminals

141a and 141b are exposed on the inner bottom surface of the cap 114. Therefore, when rainwater flows into the cap 114, the current is operated to flow between the

metal terminals

141a and 141b.

In the embodiment of the rain sensor, since the short-

circuit metal terminals

141a and 141b are connected by rainwater, the electrical resistance of the rainwater increases, thereby decreasing the voltage applied to the light emitting device 160. In order to prevent the power applied to the 160 from being weakened, a transistor for amplifying the power is preferably provided. In this case, when the rainwater does not flow and the

metal terminals

141a and 141b remain shorted, the transistor does not supply current to the light emitting device 160 in the off state, but rainwater flows into the metal terminals 141a. When 141b is connected by rainwater, as the power is amplified while the transistor is in an on state, the light is supplied to the light emitting device 160 by supplying a voltage of a predetermined magnitude or more to the light emitting device 160.

Looking at the operation of the road sign bottle configured as described above, as follows.

First, the assembled road marker bottle 100 applies an epoxy resin adhesive or the like to the anchor shaft 125 protruding downward of the main body 120 and press-fits it into a groove such as a road. If it does not rain, since the gap 145 is present between the

metal terminals

141a and 141b to maintain a shorted state, the power of the solar cell 170 is not supplied to the light emitting device 160 to emit light. The reflector located in the case 110 reflects light to ventilate the surroundings of the vehicle drivers. However, when it rains, as the rainwater flows into the grooves of the cap 114 or the waterproof member 115, the rainwater is connected to the pair of

metal terminals

141a and 141b which are short-circuited with each other. It is on. Therefore, power is supplied from the solar cell 170 to the light emitting device 160, so that the light emitting device 160 blinks at a predetermined cycle or emits light continuously. Of course, when the rain stops or rainwater is removed from the grooves, the rainwater is removed between the pair of

metal terminals

141a and 141b to maintain a short-circuit state, and the power supply of the solar cell 170 is blocked. Therefore, the light emitting device 160 is not operated. The power source of the solar cell changes the solar energy absorbed through the solar panel 150 into electrical energy and charges the solar cell 170.

In the above, the present invention has been described in detail by way of examples based on the embodiments of the present invention and the accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the contents described in the claims below.
