Hereinafter, with reference to the accompanying drawings, an embodiment of a rotation drive device and method of the TV bench according to the present invention.

Figure 2 is a block diagram showing the rotational drive device of the TV bench according to the present invention, Figure 3 is a view showing a conceptual structure in which the rotation drive device of the TV bench according to the present invention, see FIG. Looking at the configuration, it is composed of a power supply unit 14, the sensing unit 10, the microcomputer 11, the key input unit 12 and the rotating unit (13).

The power supply unit 15 supplies DC or AC power of a predetermined level to the microcomputer 12. The key input unit 13 provides the auto / manual mode key input signal to the microcomputer 12 by wire or wirelessly, and the sensing unit 10 detects the position of a person when the auto mode key signal is input by the key input unit 12. To the microcomputer 11. Here, the sensing unit 10 is composed of a plurality of position sensors (10a, 10b, 10c) as shown in FIG.

The microcomputer 12 outputs various control signals according to the key input signal of the key input unit 12 and the detection result of the sensing unit 13, and the rotating unit 13 rotates according to the control signal of the microcomputer 12. Here, the key input unit 12 is a remote controller (Remote Controller), the rotary unit 13 is located on the TV bench 2, as shown in Figure 3, the support plate on which the TV can be placed on the rotary unit 13 14 is provided.

In addition, the microcomputer 12 and the sensing unit 10 are mounted inside the TV cabinet 2 as shown in FIG. 3. At this time, since the door of the TV bench is made of transparent glass, the key input unit 12, that is, the remote controller can receive infrared radiation. A receiving unit capable of receiving such infrared rays is configured inside the microcomputer 12.

Let's look at the operation of the rotary drive of the TV bench according to the present invention having the configuration as described above.

First, when power is supplied from the power supply unit 14 to the microcomputer 912 according to the power-on control signal of the key input unit 12, the user may press the automatic or manual mode key to manually or automatically move the TV bench 2. Enter it. At this time, when the automatic mode key is input, the microcomputer 11 provides a driving control signal to the sensing unit 10 to control the plurality of position sensors 10a, 10b, and 10c of the sensing unit 10 to be driven.

The detector 1 detects the position of a person according to the driving control of the microcomputer 11 and outputs the result detected by the microcomputer 11. Here, a plurality of position sensors (10a, 10b, 10c) of the sensing unit 10 detects the position of a person, if the position of the detected person is one place, that is, if one person detects the position to the microcomputer 11 Output

The microcomputer 11 calculates the angle corresponding to the position of the person sensed by the plurality of position sensors 10a, 10b, and 10c, and provides a signal corresponding to the calculated angle to the rotating unit 13 so that the rotating unit ( 13) will rotate. Accordingly, since the pedestal 14 supporting the TV provided on the upper part of the rotating unit 13 rotates, the TV is moved to the optimal position for viewing by the viewer.

However, if the number of viewers detected by the plurality of position sensors as a result, the angle between the leftmost person and the rightmost person among the plurality of people is calculated to calculate the average value of the calculated angle. Here, generally, the angle at which the viewer can watch TV is about 120 °, and the TV is rarely watched at an angle of 120 ° or more. When the average angle is calculated in this way, the microcomputer 11 provides the rotation control signal corresponding to the average value calculated by the rotation unit 13 to control the rotation unit 13 to rotate.

If the manual mode conversion key signal is input to the microcomputer 11 by the key input unit 12, the microcomputer 11 blocks the operation of the position sensors 10a, 10b and 10c of the sensing unit 10. Then, the roller of the rotating unit 13 is rotated according to the degree of input of the left and right moving keys of the key input unit 12 of the viewer. That is, the roller 13 is rotated at an angle for viewing the optimal TV 1 at the viewer's discretion. Therefore, while the TV support 14 is rotated, the TV 1 is rotated together.

With reference to Figure 4 with respect to the rotation driving method of the TV bench corresponding to the rotary drive device of the TV cabinet according to the present invention operated as described above.

4 is an operation flowchart showing a rotation driving method of a TV bench according to the present invention.

First, when the power of the microcomputer 11 is turned on through the power supply unit 14 (S101), it is determined whether the automatic or manual mode change key of the key input unit 12 is input by the user (S102).

If the automatic mode conversion key is input, the microcomputer 11 drives the plurality of position sensors 10a, 10b, and 10c of the sensing unit 10 to detect the position of the person (S103). As a result of the detection, it is determined whether the number of detected persons is a large number (S104), and when there is only one detected person, the position and angle of the person are calculated (S108). On the other hand, when the number of people detected by the plurality of position sensors (10a, 10b, 10c) is a large number, calculate the angles for the person on the left and the person on the right (S105). When the angle is calculated, the average value of the angle is calculated (S106) to rotate the rotating unit 13, that is, the rotating roller by the calculated average angle. Therefore, many people can watch TV 1 in an optimal state without any inconvenience.

After the TV 1 is rotated as described above, the microcomputer 11 stops the driving of the plurality of position sensors 10a, 10b, and 10c of the sensing unit 10 for a predetermined time, and when the predetermined time elapses, the position sensor again. By controlling the driving (10a, 10b, 10c) to control the position of the person.

This is because the user can continuously move while watching TV 1. Accordingly, if the TV 1 is continuously rotated according to the movement of the person, it is difficult to properly watch the TV, and thus, the sensing unit 10 is driven at a predetermined time interval.

On the contrary, when the user inputs the manual mode conversion key in step S102, the microcomputer 11 blocks driving of the plurality of position sensors 10a, 10b, and 10c (S109), and the plurality of position sensors 10a, 10b, When the driving of 10c) is interrupted, the user provides the left and right movement key signals of the key input unit 12 to the microcomputer 11. Accordingly, the microcomputer 11 rotates the rotary roller of the rotary unit 13 by providing a rotation control signal to the rotary unit 13 according to the operation degree of the input left and right moving keys (S111). Therefore, the TV stand 14 is rotated according to the fire of the rotating roller, and the TV moves according to the rotation of the TV stand.

As described above, the rotary drive device and method of the TV bench according to the present invention automatically detects the position of the person without manually moving the position of the TV by manually rotating or manually rotating the TV bench according to the detected position. This makes it easy to move by simple key operation of the remote control, so that viewers can watch TV in an optimal state.
