The display 11a is a concept including not only a flat panel LCD, a PDP TV or a monitor, but also all image devices corresponding thereto. A coupling member 11b is generally attached to the display 11a, and the moving body 11 of the present embodiment includes a display 11a and a coupling member 11b. That is, the movable body 11b may be composed of only the coupling member 11b. However, when the separate coupling member 11b is not attached to the display 11a, the movable body 11 becomes the display 11a.

The first and second joint portions 15a and 15b are coupled to the movable body 11, and one end of the first and second arm portions 12 and 13 is coupled to the first and second joint portions 15a and 15b. do.

The first driving unit 16 may be coupled to any one of the first and second joint parts 15a and 15b and the first to fourth hinge members 12b, 12d, 13b, and 13d, but the first hinge member 12b It is preferable to couple to the third hinge member 13b. In addition, it is preferable that the third driving unit is coupled to at least one of the second hinge member 12d and the fourth hinge member 13d. This is to prevent the first and second arm portions 12 and 13 from becoming free ends from the fixture 14. The configuration and operation method of the first driver 16 will be described in more detail as follows.

3 is a side view of the first drive unit according to the first preferred embodiment of the present invention, and FIG. 4 is a cross-sectional view of a rotating unit of the first drive unit according to the first preferred embodiment of the present invention. 3 and 4, a first driving unit 16, a power unit 21, a rotating unit 22, a clutch unit 222a, a driving shaft 222, and a driven shaft 221 are illustrated. FIG. 3 shows the first driver 16 coupled to the first hinge member 12b of the first arm 12, but the second driver coupled to the second arm 13 is similarly configured.

As shown in FIG. 3, the first driving unit 16 includes a power unit 21 and a rotating unit 22. The power unit 21 is composed of a motor, the rotating unit 22 is an axis that serves to transfer the power of the motor to the outside. As shown in FIG. 3, the power unit 21 and the rotating unit 22 are coupled to the first link member 12a and the second link member 12c in the first hinge member 12b, respectively. As a result, when the first driving unit 16 is driven, the first arm 12 of FIG. 1 is extended or contracted.

However, when the driven shaft 221 is forcibly rotated from the outside, the frictional force of the clutch portion 222a is smaller than the cogging torque of the motor. Here, the cogging torque refers to the force required to forcibly rotate the stopped motor from the outside. As such, when the frictional force of the clutch unit 222a is smaller than the cogging torque of the motor, damage due to forced rotation of the motor due to external force can be prevented. To adjust this friction force, a washer 222b may be interposed between the clutch portion 222a and the driven shaft.

On the other hand, the distance sensor 17 is attached to the moving body 11 of FIG. The distance sensor 17 detects the distance between the movable body 11 and the fixed body 14 or the movable body 11 and the wall in real time to prevent a collision with the wall surface. The distance sensor 17 is preferably attached to the corner of the moving body 11, in particular the display 11a.

When the movable body 11 is rotated from side to side at a predetermined angle, the extension degree of the first arm part 12 and the second arm part 13 is measured. Do it differently. Thus, the movable body 11 is rotated to one side.

5 is a side view and a partially enlarged view of a display rotating apparatus according to a second preferred embodiment of the present invention, Figure 6 is a plan view of a display rotating apparatus according to a second preferred embodiment of the present invention. 5 and 6, the display rotating device 50, the moving body 51, the first arm 52, the second arm 53, the fixing body 54, the first joint part 55a, and the first 2 joint part 55b, display 56, connecting part 59a, 59b, coupling part 58, pivoting part 57, tension member 571, roller member 572, motor part 573, motor 573a, pulley 573b, tension adjusting device 574, and elastic body 60 are shown.

The operating manners of the first and second arm parts 52 and 53 of the present embodiment are the same as those of the first embodiment shown in FIGS. 1 to 4, and will be described below based on differences. The movable body 51 and the display 56 of the present embodiment are hinged at the coupling portion 58 as separate components. Accordingly, as shown in the embodiment of FIG. 1, the movable body 11 can be rotated left and right by the first and second arm portions 52 and 53, and the display 56 can be rotated up and down based on the movable body 51. You can.

The vertical rotation method of the present embodiment will be described in detail with reference to the enlarged cross-sectional view of FIG. 5. The display 56 has connection portions 59a and 59b formed therein, and a tension member 5711 is coupled to the connection portions 59a and 59b. A separate member may be interposed between the connecting portions 59a and 59b and the display 56, and the connecting portions 59a and 59b may be formed in the member. The connecting portions 59a and 59b are preferably formed symmetrically about the coupling portion 58 which is a rotational axis so that the display 56 can move up and down smoothly.

An elastic body 60 is coupled between the display 56 and the movable body 51 so as to face the gravity moment of the display 56. Flat panel TVs typically weigh tens of kilos. When the elastic body 60 is not coupled between the movable body 51 and the display 56 as shown in FIG. 5, the display 56 is struck down around the coupling part 58, and the tension member is caused by such a moment. 571 becomes a high tension state. In this situation, when the motor is operated, the motor is overloaded due to the tension of the tension member 571.

 The elastic body 60 may be a coiled spring as shown in FIG. 5, but various modifications may be possible if the same has the same function. In addition, the elastic body 60 may connect any portion of the moving body 51 and the display 56 as long as it prevents the drooping phenomenon of the display 56 due to the gravity moment.

On the other hand, the rotating part 57 is composed of a tension member 571, a roller member 572, a motor portion 573, a motor 573b, a slip pulley (573a), a tension adjusting device (574).

The tension member 571 may be a wire, a belt, a chain, or the like. This example used a wire. As shown in the figure, the tension member 571 is coupled to the connecting portions 101a and 101b. The tension member 571 is combined with a roller member 572 for guiding a path and a motor portion 573 for supplying power to the tension member 571. Two roller members 572 were used in the embodiment of FIG. 1, but the number of the roller members 572 may vary depending on the situation.

The motor unit 573 includes a slip pulley 573a and a motor 573b, and a tension member 573 is coupled to the slip pulley 573a. In FIG. 1, since the tension member 573 is a wire, the slip pulley 573b corresponding thereto is coupled. However, when the tension member 573 is a chain, a sprocket corresponding thereto may be used. On the other hand, the motor portion 573 may be coupled to the movable body 51 as shown in FIG. 5, but may be coupled to the display 56.

In the slip pulley 573a described in this embodiment, the frictional force is adjusted, and when the motor 557b rotates, the tension member 571 does not slip, but the external condition in the situation where the motor 573b does not operate. When the tension member 571 is moved by a forced force, it means a pulley in which slip occurs. The operation principle of the slip pulley 573a will be described in detail as follows.

 The slip pulley 573a transmits power of the motor 573b to the tension member 571 and ultimately rotates the display 56 up and down. Therefore, the friction force between the slip pulley 573a and the tension member 571 should be large enough to move the display 56. That is, when the motor 573b rotates, a slip phenomenon should not occur between the slip pulley 573a and the tension member 571. On the other hand, when the tension member 571 is forcibly moved from the outside, instead of driving the motor 573b, slip occurs and the motor 573b does not forcibly rotate. That is, the friction force between the slip pulley 573a and the tension member 571 should be smaller than the cogging torque of the motor 573b.

The tension adjusting device 574 is positioned on the path of the tension member 571, and is coupled to the tension member 571. The tension control device 574 is also a kind of pulley. Only the position is variable to adjust the tension. Since the shape and configuration of the tension control device 574 is obvious to those skilled in the art, the following detailed description will be omitted. The coupling position of the tension adjusting device 574 of the embodiment of Figure 5 is coupled to be fixed to the moving body 51, it may be coupled to the display 56.

7 is a perspective view of a display rotating apparatus according to a third preferred embodiment of the present invention. Referring to FIG. 7, the display rotating device 70, the moving body 71, the display 71a, the coupling member 71b, the first arm portion 72a, the second arm portion 72c, the third arm portion 73c and the first 1 hinge member 73a, 2nd hinge member 73b, 3rd hinge member 73c, 4th hinge member 73d, 5th hinge member 73e, 6th hinge member 73f, and power part ( 74, the first joint portion 75a, the second joint portion 75b, and the distance sensor 77 are shown.

The present embodiment relates to a display rotating device 70 capable of rotating the movable body 71 up, down, left and right by three first to third arm parts 72a, 72b, and 72c. Since the components of the first to third arm portions 72a, 72b, and 72c have already been sufficiently described in FIG. 1, the following description will focus on differences.

The first to third arm parts 72a, 72b, and 72c of the present embodiment have a structure capable of joint motion, one end of which is coupled to the movable body 71 and the other end of which is coupled to the fixture 74. Coupling with the movable body 71 is made through the first to third joint portions 75a, 75b, 75c. The first to third joint portions 75a, 75b, 75c are made of ball joints, and can be rotated in one or more directions. Referring to the specific coupling position of the first to third joint portions 75a, 75b, 75c, the moving body at a point separated from an imaginary straight line connecting the first joint portion 75a and the second joint portion 75b ( The third joint portion 73c is coupled to 71. The first to third arm portions 72a, 72b, and 72c are coupled to the first to third joint portions 75a, 75b, and 75c, thereby allowing the movable body 71 to rotate in various directions.

On the other hand, between the other end of the first to third arm portions (72a, 72b, 72c) and the fixing body 74 through the second, fourth, and sixth hinge members (73b, 73d, 73f) respectively.

On the other hand, the distance sensor 77 is attached to the corner of the moving body 71, in particular the display 71b. The distance sensor 77 detects a distance from the fixture 74 or the wall to prevent the display 71b from hitting the wall during the rotation. In addition, as described in the first embodiment of FIG. 1, the driving unit is coupled to the first to third arm units 72a, 72b, and 72c to drive the first to third arm units 72a, 72b, and 72c.

The operation method of the display rotating apparatus 70 according to the present embodiment will be briefly described. When the display 71b is input to a command to rotate the display 71b up, down, left and right, the first to third arm parts 72a, 72b, and 72c may be used. The attached driving unit is operated to extend the first to third arm portions 72a, 72b, 72c by a predetermined amount of rotation. As a result, the display 71b is rotated at an angle desired by the viewer. In addition, the distance between the wall surface and the display 71b is detected by the distance sensor 77 in real time, and when a collision occurs with the wall during the rotation of the display 71b, by extending the dark portion close to the point where the collision occurs, The distance of the display 71b is secured.

FIG. 8 is a perspective view of a display rotating apparatus according to a fourth preferred embodiment of the present invention. In this embodiment, the movable body 81 is rotated using four arm portions 82a, 82b, 82c, and 82d.

Hereinafter, a method of rotating the display rotating apparatus will be described in detail with reference to the embodiment of FIG. 7.

FIG. 9 is a flowchart illustrating a method of driving a display rotating apparatus according to a fifth exemplary embodiment of the present invention. The driving method of the present exemplary embodiment will be described with reference to the display rotating apparatus of FIG. FIG. 7 illustrates a display rotating device 70 including three first to third arm parts 72a, 72b, and 72c, but the embodiment corresponding to the flowchart of FIG. 9 is a display rotating device including three or more arm parts. Applies to all 70.

As shown in FIG. 7, when the first to third arm portions 72a, 72b, and 72c are planarly coupled to the movable body 71, the movable body 71 is rotated by individually controlling the lengths of the first to third arm portions 72a. Can be controlled in three dimensions. Herein, the planar coupling of the first to third arm parts 72a, 72b, and 72c is at a point spaced apart from an imaginary straight line connecting the coupling point of the first and second arm parts 72a, 72b and the moving body 71. This means that the third arm portion 72c is coupled. The planar coupling of the first to third arm parts 72a, 72b, and 72c and the movable body 71 enables the movable body 71 to be rotated at various angles.

Referring to the rotation of the display rotating apparatus 70 on the basis of the flowchart of FIG. 9, S91 is a step of inputting a command to rotate the moving body 71. The display rotating device 70 maintains the state in close contact with the fixture 74 in the initial state. In this case, the person watching the display from the front can secure a good audiovisual. However, as the viewer moves around, the viewing range of the display is reduced. Therefore, the viewer can adjust the viewing angle of the display by rotating the moving body 71 using the remote controller or the like. The input signal transmitted from the remote controller is received by a receiver attached to the display rotating device 70.

S92 of FIG. 9 calculates the rotation amount of each drive part of the plurality of arm parts 72a, 72b, 72c so as to correspond to the distance and angle with respect to the fixed body 74 of the moving body 71 from an input signal, Generating a control signal to be transmitted to the driver. That is, the signal input from the remote controller is calculated by the controller as the amount of rotation of the driver. The calculated value becomes a reference value and is compared with a comparison value to be described later.

In step S93 of FIG. 9, a control signal is input to rotate each driving unit of the plurality of arm units. The motor of the drive unit is operated by the amount of rotation determined by the control of the control unit. The amount of rotation of the drive unit is measured by a sensor coupled to the drive unit and is input as a comparison value. Such sensors can use Hall elements and magnets.

S94 of FIG. 9 is a step of determining a comparison value by measuring the amount of rotation of the drive unit. Hall element and magnet (Magnet) is coupled to the drive unit, the amount of rotation of the drive unit is accurately measured.

S95 of FIG. 9 calculates a difference between the comparison value and the reference value, and stops the driving unit in the case of an error range, and rotates the driving unit by inputting a control signal to the driving unit again when it is out of the error range (S93). Is continued until the difference between the reference value and the comparison value is within the margin of error. Here, the error range is a numerical value input to the controller.

On the other hand, during the rotation of the display rotating apparatus 70 in this manner, the movable body 71 may collide with the fixed body 74 for various reasons. Therefore, the distance sensor 77 transmits a distance signal between the moving body 71 and the fixed body 74 to the control unit in real time, and the control unit emphasizes the rotation of the driving unit or collisions when the distance signal is within the error range. To prevent this, the arm in the collision direction can be extended. Here, the 'error range' means a minimum distance input in advance to prevent a situation in which the movable body 71 collides with the fixed body 74 such that the distance between the movable body 71 and the fixed body 74 becomes zero.

The control method is to prevent the moving body 71 and the fixed body 74 from colliding by using the distance sensor 77, the rotation of the hinge member that is the rotation axis of the arm portion to the resistance element attached to the hinge member After measuring and transmitting to the control unit, the position of the moving body 71 according to the amount of rotation of the hinge member coupled to each arm portion, the control unit controls the arm portion to prevent the moving body 71 from colliding with the fixed body 74 Rotation can also be controlled.

Although the preferred embodiments of the present invention have been described above, those skilled in the art may variously modify and modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. It will be appreciated that it can be changed.

According to the preferred embodiment of the present invention as described above, the display can be spaced apart from the support to secure the rotation angle of the display, and the separation and rotation can be performed automatically and manually, thereby increasing convenience.
