The communication unit includes a modem for wireless communication and a port for wired communication.

That is, the above-described notice information may be wirelessly received on the display through a modem and a terminal capable of processing and transmitting and receiving information, such as a smart terminal,

It is also possible to connect directly to a direct connection terminal (including a connection with a wire) such as USB or an external hard drive through a port through a wire, etc., so that the notice information they have can be received on the display.

The cradle functions to mount the display so that the display can be installed on one side (the side wall of the cargo compartment) of the sign car, as shown in FIG. 2 of the accompanying drawings.

2 is a side view showing an example in which the electronic display board for a vehicle according to the present invention is coupled to a sign car.

According to FIG. 2 of the accompanying drawings, the cradle is directly coupled to the side wall of the cargo compartment of the sign car, and the display may be coupled to the upper side of the mount. In this case, the mounting area of the mount is the side wall of the cargo compartment of the sign car. It can be a vehicle roof or a variety of choices.

In addition, the combination of the mount and the display may be variously selected and applied as long as it is a range that is obvious to a person skilled in the art, such as bolting, and a range that can be derived based on knowledge at the time of filing.

For practical application of the electronic display board for a vehicle according to the present invention, reference may be made to FIG. 3 of the accompanying drawings.

According to FIG. 3 of the accompanying drawings, the notice information output through the display may be various, such as text, picture, graphic, or video, and in particular, since the notice information is received and output from a terminal, etc., the advantage that can be widely applied even in multiple lanes Have.

On the other hand, depending on the design conditions, the cradle may be configured as shown in [Table 1] to mount the display so as to be coupled to the sign car.

[Table 1] shows another embodiment of the electronic display board for a vehicle according to the present invention.

Referring to this [Table 1], the cradle is extended so as to contact the inner surface of the side wall of the cargo compartment of the sign car, and the pin is coupled to the lower end of the sign car, and may include a through hole for this purpose.

In addition, one side of the cradle is composed of a support plate of [Table 1], the support plate is configured to have a shape bent twice in the vertical-horizontal-vertical direction, and is configured to include a through hole in the vertical surface of the uppermost side. .

The support plate is coupled to one side of the cradle with bolts through a through hole, and is positioned to surround the upper surface of the side wall of the cargo compartment of the sign car by the remaining horizontal and vertical surfaces, so that the cradle can be stably fixed.

On the other hand, based on [Table 1], the cradle may be configured such that two supports are coupled through a pin coupled to the lower end of the cradle described above.

That is, the pin coupled to the lowermost end is positioned so as to pass through the side wall of the cargo compartment of the sign car from the cradle, and for this purpose, it is preferable that the side wall of the cargo compartment of the sign car also includes a through hole.

In this way, through the pins exposed to the outside of the side wall of the cargo compartment of the sign car, the two supports are stacked and joined to have a direction inclined upward with respect to the cradle. At this time, a nut is attached to the end of the pin to prevent separation of the support. Or you could have the caps attached.

A side support plate having a shape of'┌┐' is coupled to the upper end of the support, and the side support plate has a through hole formed on one side of the vertical surface, and a through hole is also formed at the upper end of the support. The upper end where the hole is formed is located inside the side support plate so that the two through holes are located in a straight line as shown in [Table 1].

In addition, a part of the upper side of the sidewall of the screen compartment of the sign car is inserted into the remaining inner region of the side support plate so that it can be coupled.

In addition, the support has a telescope shape that can be variable in length in the form of an antenna. Alternatively, the support may be replaced with a cylinder.

Accordingly, the two supports can be moved away or closer. These supports help to securely and stably fix the cradle, while, for example, even when the vehicle is stopped on a slope, the display does not incline along the slope and the driver's position. Helps to fix it in an inclined direction so that it has an upright position.

For example, by narrowing the spacing of the supports, the holder and the support plate of the holder are fixed to any one support or side support plate, so that the holder can be stably fixed in an inclined direction from the sign car. Even when the vehicle is stopped or parked in the direction in which the display is inclined, it is possible to have a direction that is perpendicular to the plane.

On the other hand, the above-described support plate may be configured as shown in [Table 2].

[Table 2] shows the structure according to another embodiment of the support plate among the electronic display boards for vehicles according to the present invention.

The support plate is configured to have an extension plate further protruding downward at a point bent from the uppermost vertical plane to the horizontal plane.

Between the two inner surfaces facing between the extension plate and the lowermost vertical surface, the two rollers coupled through the shaft have a certain distance and are joined together, at this time, the shaft in the form of interpolation on the two opposite inner surfaces. Let it be combined.

In addition, a pad made of a flexible material (rubber, silicone, etc.) is coupled to the two rollers to move the rollers along an axis.

Accordingly, the pad directly abuts on one surface of the side wall of the cargo compartment of the sign car, thereby improving frictional force so that stable fixation is possible, and at the same time, when moving the cradle, smooth movement is possible.

In addition, a plurality of holes may be formed in the horizontal surface of the support plate. In this case, if foreign matters are stained due to the long contact of the pad to the side wall of the cargo compartment of the sign car, the surface of the corresponding pad is changed according to the movement of the support plate. When located on the lower side of the horizontal plane, the purpose is to allow foreign substances to fall due to ventilation of the hole.

In addition, according to the ventilation function of the hole, it may be useful to prevent foreign matters from being adsorbed to the surface of the pad that is not in use.

'의 단면형상을 가지도록 함으로써, 통풍에 유리하도록 할 수도 있다. 이러한 오목만곡면은 양방향으로 형성될 수도 있다.In addition, although not shown in [Table 2], '

By having a cross-sectional shape of', it may be advantageous for ventilation. This concave curved surface may be formed in both directions.

What has been described with reference to the drawings above is a description of only the main matters of the present invention, and it is obvious that the present invention is not limited to the configuration of the drawings as various designs are possible within the technical scope.
