That is, the second bearing 154 may include upper bearings 154a and 154b provided on the upper portion of the guide rail 142 and lower bearing 154c provided on the lower portion of the guide rail.

In this case, the upper bearings 154a and 154c may be provided in the front-rear direction based on the guide rail 142 to guide the movement of the guide rail 142 with respect to the upper and lower parts and the front-rear direction of the guide rail 142. As the second bearing 154 is provided on the front, rear, left, and right sides of the guide rail 142, the rotation force required for the rotation of the driving belt 144 may be easily provided, and the guide rail 142 may slidably move. Can be.

On the other hand, the drive motor 152 may be located under the guide rail 142, in the pedestal device 100 according to an embodiment of the present invention an example in which the drive motor 152 is located below the lower bearing (154c) It will be described with an example. The driving motor 152 may be in contact with one surface of the driving belt 144 so that the driving belt 144 may be caught by the driving motor 152. That is, the surface in which the driving motor 152 and the driving belt 144 partially contact is formed, so that the driving motor 152 may transmit the driving force to the driving belt 144.

In addition, a guide shaft 156 is provided between the second bearing 154 and the driving motor 152 in the driving housing 150_see FIG. 2 and provides a tension to the driving belt 144 by the driving belt 144. It may be provided. Since the driving belt 144 is bent by the guide shaft 156 and then mounted on the driving motor 152, the area of the driving belt 144 meshing with the driving motor 152 may increase. As described above, as the area of the driving belt 144 engaged with the driving motor 152 by the guide shaft 156 increases, the driving force transmitted to the driving belt 144 may be increased, and the sliding motion of the antenna 20 may be increased. Precise and safe control

In addition, the driving housing 150 may further include a bearing support plate 158 for supporting the second bearing 154. The bearing support plate 158 supports and fixes the second bearing 154 to the drive housing 150 to stably provide the rotational force to the drive belt 144.

In the above, the case in which the member is engaged with the driving motor 152 and transmits the driving force to the guide rail 142 has been described as an example, but is not necessarily limited thereto, and may be formed of a chain or pulley / belt, a winding spring, or the like. have.

Referring back to FIGS. 1 to 3, both ends of the non-rotation driving unit 140 are supported and fixed to the rear surface of the antenna 20, and an elevation capable of tilting the antenna 20 up and down based on the horizontal diameter of the antenna 20. The unit 160 may be provided. The elevation unit 160 may include a third bearing 164 and a driving motor (not shown), and the third bearing 164 may form a rotation shaft in which the antenna 20 can be flipped up and down.

In addition, a wave guide unit 182 may be formed at the center of the rear surface of the antenna 20 to guide the received satellite signal to a set top box (not shown). The wave guide unit 182 may be provided at the rear of the antenna 20, and in particular, may be connected to the LNB 40 that receives the satellite signal.

The wave guide unit 182 may include a flexible wave guide 184. The flexible wave guide 184 rotates from side to side in the circumferential direction of the antenna 20 by the guide rail 142, and thus, the wave guide 184 is a radio wave conduit from a production, assembly error, or external shock or vibration. The wave guide part 182 may be provided with fluidity to prevent the wave guide part 182 from being damaged.

As described above, since the guide rail 142 is positioned below the rear surface of the antenna 20, a space for mounting the LNB 40 can be sufficiently secured. That is, when the antenna 20 rotates according to the satellite signal, various devices located on the rear surface of the antenna 20 also rotate. At this time, the back of the antenna 20 should be secured in the space for the rotation of the various devices can be rotated due to the minimum device to be mounted for the rotation of the antenna 20 is difficult to secure space. At this time, by sliding the antenna 20 using the guide rail 142, it is possible to minimize the device for rotating the antenna 20 around the axis of rotation passing through the center of the antenna 20. By minimizing the device necessary for the rotation of the antenna 20, it is easy to ensure a sufficient free space on the back of the antenna 20.

4 to 6 are diagrams showing the operating state of the pedestal according to an embodiment of the present invention. That is, FIG. 4 is a view illustrating a state in which the antenna 20 slides in the circumferential direction by the non-rotation driving unit 140 in one embodiment of the present invention, and FIG. 5 is vertical by the rotating unit 120. FIG. 6 is a view illustrating a state in which the antenna 20 rotates left and right about a rotation axis, and FIG. 6 illustrates a state in which the antenna 20 rotates up and down about the horizontal diameter of the antenna 20 by the elevation unit 160. Figure is a diagram.

4 to 6, the antenna 20 may adjust the position according to the position of the satellite.

For example, when the satellite signal is received from the left side of the antenna 20 in the in-situ state, the right side of the driving belt 144 is tightened and the left side is released so that the antenna 20 may rotate to the left side. That is, the guide rail 142 may be changed to a position where the main reflector of the antenna is the most easy to receive the satellite signal according to the satellite signal received by the antenna 20. Here, the guide rail 142 may change the position of the antenna 20 by controlling the driving direction of the guide rail 142 by repeatedly tightening and releasing the driving belt 144.

At this time, the guide rail 142 may rotate about 80 ° to 100 ° from side to side along the circumferential direction of the antenna 20. In one embodiment of the present invention, the guide rail 142 rotates about 90 °. For example, but the rotation angle can be changed according to the conditions of the invention.

In addition, the rotating unit 120 may rotate the antenna 20 to the left or right about the vertical axis of rotation of the rotating unit 120 according to the position of the satellite. For example, when a satellite signal is received from the left side of the antenna 20 at the antenna 20 in position, the rotating unit 120 rotates to the left side so that the antenna 20 can be positioned in the same direction as the satellite signal. .

On the other hand, when the satellite signal is received from the upper or lower portion of the antenna 20 to the antenna 20 in position, the elevation unit 160 is the antenna 20 up and down based on the horizontal diameter of the antenna 20 Allow it to flip over. In general, the satellite signal may be received at the top of the antenna 20, the antenna 20 may be changed in position according to the direction of the satellite signal. At this time, the third bearing 164 of the elevation unit 160 allows the antenna 20 to be flipped upward or downward through rotation, so that the satellite signal can be correctly received.

By providing the non-rotating drive unit 140 including the guide rail 142 on the back of the antenna 20 as described above, it is possible to ensure the proper movement of the antenna 20 without rotating the antenna 20 in the circumferential direction have. That is, the antenna 20 may be rotated left and right even if a separate rotating shaft for rotating the antenna 20 is not formed by the non-rotating driver 140.

In other words, the pedestal device 100 is a vertical axis of rotation (a) by the rotating part (see 120_ Fig. 1) for rotating the antenna 20 360 degrees and the elevation unit 160 is flipped up and down (160 degrees) 1) the horizontal axis of rotation (b) may be formed so as to intersect or spaced apart. In this case, the non-rotational drive unit 120 may drive the antenna 20 together with the vertical rotation shaft a and the horizontal rotation shaft b without forming a separate rotation shaft. According to the above configuration, the pedestal device 100 can receive the satellite signal by rotating the antenna 20 according to the satellite signal even though it has two rotation axes.

In addition, the guide rail 142 is mounted on the lower rear surface of the antenna 20, to secure a space between the LNB 40 and the guide rail 142, thereby sufficiently securing the rotation space of the antenna 20. Therefore, even when a mobile body having a large moving range can accurately receive the satellite signal according to the satellite signal, the reliability of the pedestal device 100 can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
