FIG. 5 is a schematic view of the left side, and FIG. 5 is a schematic view of a display positioning apparatus that performs an extension operation. Hereinafter, the positioning of the display for convenience of clear understanding and explanation of the present invention will be described as an example, but those skilled in the art should understand that the scope of the present invention is not limited thereto.

The display positioning apparatus includes a fixture 10, an arm 20, a tilt member 30, a connection member 40, and a controller (not shown). The fixture 10 is fixed to a wall or the like to fix the display positioning apparatus at a predetermined position. The arm 20 has one end hinged to the fixture 10 about the first hinge shaft M1 and the other end thereof to the second end. It is hinged to the connecting member 40 around the hinge axis (M2). The tilt member 30 is hinged around the connecting member 40 and the third hinge axis M3, and the device to be positioned at a predetermined position such as the display 50 is detachably attached to the tilt member 30. It is possible to combine the display 50 of various specifications. Here, the first hinge axis M1 and the second hinge axis M2 are substantially parallel, and the second hinge axis M2 and the third rotation axis M3 are substantially vertical.

The tilt member 30 is hinged around the third hinge axis M3 to perform a tilt down or tilt up operation and to adjust the vertical rotation angle of the mounted display 50. Can be.

Each hinge shaft M1, M2, M3 is gear-coupled with the rotation shaft of the motor. Accordingly, the rotational force of the motor is provided to the arm 20, the connecting member 40, and the tilting member 30 which are hinged around the hinge shafts M1, M2, and M3 to enable the rotational motion and the tilting motion. More specifically, the arm 20 may be rotated forward or backward within a predetermined angle about the first hinge axis M1, and the connecting member 40 may be rotated within a predetermined angle about the second hinge axis M2. In the forward or backward rotation is possible (see Figs. 2 and 3), the tilt member 30 around the third rotation axis (M3) can be tilted up and down within a predetermined angle (see Fig. 4). As the arm 20 or the connecting member 40 rotates about the first hinge axis M1 or the second hinge axis M2, the display 50 may be horizontally moved (see FIG. 5), and the third As the tilt member 30 is tilted about the rotation axis M3, the vertical angle of the display 50 may be adjusted (see FIG. 4).

Hereinafter, for convenience of understanding and explanation of the invention, a motor coupled to the first hinge shaft M1 may be an arm swivel motor, and a motor coupled to the second hinge shaft M2 may include a body swivel motor and a third hinge shaft M3. The motor coupled to the motor is called a tilt motor. And the small value of the angle formed between the fixture 10 and the arm 20 around the first hinge axis (M1) to the arm gear angle (S1 in FIG. 2), the arm (2) around the second hinge axis (M2) 20 and the smaller value of the angle formed by the connecting member 40 with the connecting member 40 around the body gear angle (S2, S2 'in FIG. 2, S2 "in FIG. 3) and the third hinge axis M3. The smaller value of the angle formed by the tilt member 30 is referred to as a tilt angle (S3 in FIG. 4).

It is assumed that the arm gear angle increases when the arm swivel motor rotates forward, and decreases when the arm swivel motor rotates. It is assumed that the body gear angle decreases when the body swivel motor rotates forward and the body gear angle increases when the body swivel motor rotates in reverse. In addition, it is assumed that the tilt angle decreases when the tilt motor rotates forward and the tilt angle increases when the tilt motor rotates in reverse.

The rotation angle of the arm swivel motor, the body swivel motor and the tilt motor is controlled by the controller. The drive motor, such as an arm swivel motor, a body swivel motor, or a tilt motor, may further include a rotation sensing element. For example, in the case of having a hall sensor and a magnet, either the hall sensor or the magnet is coupled to the rotational axis of the drive motor, and the other is coupled to the housing of the drive motor. Its position is fixed. In this case, the rotation angle of the corresponding driving motor can be known from the change of magnetic flux from the magnetic body detected by the Hall sensor, and the control unit receives the rotation angles by the magnetic body and the Hall sensor and controls only the rotation angle of the driving motor as necessary. It is possible. Here, the drive motor is connected to the gear box coupled to one or more gears, serves to properly adjust (deceleration) the rotation of the motor.

In the above description, the Hall sensor and the magnetic material are described as examples of the rotation sensing element. In addition, various elements capable of detecting the degree of rotation of the rotating shaft by the driving motor, such as a magnetoresistive element, a potentiometer, and a gyro system, are described. Those skilled in the art will appreciate that it is available.

An operation of the display positioning apparatus will be described with reference to FIGS. 2 to 5. Basic operations of the display positioning apparatus include a left swivel, a right swivel, a tilt down, a tilt up, an extension operation, and the like.

(1) leftward swivel motion

2, the fixed body 10 and the arm 20 hold the constant arm gear angle S1. The initial body gear angle between the arm 20 and the connecting member 40 (the tilt member 30 is fixed integrally with the connecting member 40 during the swivel operation) is maintaining S2 (SS position) The connecting member 40 is swiveled to the left about the second hinge shaft M2 by the forward rotation driving of the swivel motor (LS position).

The forward rotation of the body swivel motor rotates the connecting member 40 in the forward direction so that the display 50 mounted on the tilt member 30 is swiveled leftward. The leftward swivel limit LSL refers to the body gear angle when the display 50 can no longer be left swiveled by the wall and has various values depending on the size of the display 50. Or it may be the case that it can no longer be left swiveled due to the structural limitations of the display positioning device.

For convenience of understanding and explanation of the present invention, the connecting member 40 is rotated only around the second hinge axis M2 during the left swivel operation. However, the arm is formed around the first hinge axis M1. 20 may rotate in the forward direction, and the arm 20 and the connecting member 40 may rotate in the forward direction simultaneously or sequentially about the first hinge axis M1 and the second hinge axis M2.

(2) right swivel motion

3, the fixed body 10 and the arm 20 hold | maintain the constant arm gear angle S1. The initial body gear angle between the arm 20 and the connecting member 40 (the tilt member 30 is fixed integrally with the connecting member 40 during the swivel operation) is maintaining S2 (SS position) The connecting member 40 is swiveled to the right about the second hinge shaft M2 by the reverse rotation driving of the swivel motor (RS position).

The display 50 mounted to the tilt member 30 is swiveled rightward by the reverse rotation of the body swivel motor. The rightward swivel limit (RSL) refers to the body gear angle when the display 50 can no longer be swiveled by the wall and has various values depending on the size of the display 50. Alternatively, there may be cases in which the swivel can no longer be swiveled due to the structural limitations of the display positioning device.

For convenience of understanding and description of the present invention, the connection member 40 is rotated only around the second hinge axis M2 during the rightward swivel operation. However, the arm is formed around the first hinge axis M1. 20 may rotate in reverse direction, and the arm 20 and the connecting member 40 may rotate in the reverse direction simultaneously or sequentially about the first hinge axis M1 and the second hinge axis M2.

(3) tilt movement

Referring to FIG. 4, in the tilting operation, the fixing body 10, the arm 20, and the connecting member 40 are integrally fixed and hinged around the connecting member 40 and the third hinge axis M3. Combined tilt member 30 rotates up and down.

The tilt angle is tilted down or tilted by the tilt member 30 on which the display 50 is mounted at the initial position (TS positioning) about the third hinge axis M3, and the forward or reverse rotation driving of the tilt motor. It means the angle (S3) between the position of the up tilt member 30 (tiled up TU position in FIG. 4). The tilt angle assumes that the tilt motor has a negative value due to the tilt down operation in the forward rotation, and the tilt motor has a positive value due to the tilt up operation in the reverse rotation.

The tilt member 30 rotates downward by the reverse rotation driving of the tilt motor to perform the tilt down operation, and the tilt member 30 rotates upward by the forward rotation driving of the tilt motor to perform the tilt up operation.

The tilt up limit TUL refers to the tilt angle when the display 50 can no longer be tilted up by the wall and has various values depending on the size of the display 50. Or it may be the case that can no longer be tilted up due to the structural limitations of the display positioning device. The tilt down limit TDL refers to the tilt angle when the display 50 can no longer be tilted down by the wall and has various values depending on the size of the display 50. Or it may be the case that can no longer be tilted up due to the structural limitations of the display positioning device.

(4) Extension operation

Referring to FIG. 5, the display positioning apparatus according to the exemplary embodiment of the present invention may be located at the first extension position E1 to the display 500 to be spaced apart from a wall and the like to minimize the space and occupy a minimum space. Tilt member 40 equipped with 50 can be made to be closest.

In order to minimize the distance from the wall, the display positioning device requires at least two arm swivel motors and a body swivel motor, that is, two motors, and the display 50 is driven by the arm swivel motor and the body swivel motor driven together. Rotate, tilt, and extension to your desired location without colliding with the wall.

The arm swivel motor and the body swivel motor are driven equally (so that the arm gear angle and the body gear angle increase equally) so that the display 50 moves forward or backward in parallel with the wall.

When the arm gear angle and the body gear angle are minimum (for example, 0), the display 50 is spaced apart from the wall to the minimum by D1, and the arm gear angle and the body gear angle are driven by the arm swivel motor and the body swivel motor. In this case, the display 50 is spaced apart from the wall by D2 to provide a closer distance to the user located in front of the display 50.

(5) other

Although the swivel operation, the tilt operation, and the extension operation have been described as being performed separately, those skilled in the art should understand that each operation may be performed at the same time. That is, swivel and tilt, extension and swivel, extension and tilt, extension and swivel and tilt operations may be performed at the same time.

Hereinafter, a method of positioning the display positioning apparatus according to an embodiment of the present invention at a specific position will be described with reference to the flowchart.

6 is a flowchart illustrating a method of performing an auto calibration function of the display positioning device according to an embodiment of the present invention. The automatic calibration function is based on the tilt down limit (TDL), tilt up limit (TUL), left swivel limit (LSL) and right swivel limit (RSL) of the display positioning device. ) Is performed to update and save a new one.

The display positioning device is different from the tilt down limit, the tilt up limit, the left swivel limit, and the right swivel limit according to the location where the display positioning device is installed, the size of the display mounted on the display positioning device, and the like. Thus, although the user may enter each limit directly, an automatic calibration feature allows the user to set the tilt down limit, tilt up limit, left swivel limit, and right swivel limit that are appropriate for the currently installed location, mounted display.

If an input corresponding to performing the auto calibration function is input, it is assumed that the initial display positioning device is set up at the reference position (step S600). Here, in the reference position, the arm gear angle S1, the body gear angle S2, and the tilt angle S3 are all 0 degrees. The angles of the arm gear angle, the body gear angle, the tilt angle, and the like can be measured using the rotation sensing elements provided in the drive motors such as the arm swivel motor, the body swivel motor, the tilt motor, and the like.

It is determined whether the arm gear angle S1 is 45 degrees (step S602). If the arm gear angle is not 45 degrees, the arm swivel motor is driven forward rotation (step S604). If the arm gear angle is 45 degrees, the flow proceeds to step S606. It is determined whether the body gear angle S2 is 45 degrees (step S606). If the body gear angle is not 45 degrees, the body swivel motor is driven forward (step S608). If the body gear angle is 45 degrees, the flow proceeds to step S610.

Here, steps S602 and S604 and steps S606 and S608 may be performed in reverse order or simultaneously.

In the present embodiment, the tilt angle, tilt up limit, leftward swivel limit and rightward swivel limit are measured on the basis of the limit measurement criteria when the arm gear angle and the body gear angle are 45 degrees. However, those skilled in the art should understand that the tilt down and tilt up limits, the left swivel limit and the right swivel limit can be measured in various cases (eg 30 degrees for the female gear and the body gear angle). .

The tilt motor is rotated forward (step S610), and it is judged whether there is a change in tilt angle S3 (step S612). If the tilt angle changes, steps S610 to S612 are repeated. If the tilt angle does not change, the flow advances to step S614 to set the current tilt angle to the tilt down limit TDL. Here, the tilt angle does not change because (1) the display positioning device is no longer mechanically and structurally tilted down, or (2) the display is in contact with a wall and no longer tilts down. Therefore, the tilt angle in this case is set to the tilt down limit. However, of course, the tilt down limit may be set by the user or the tilt down limit may be set by another method.

Thereafter, the tilt motor is reversely rotated (step S616), and it is determined whether there is a change in the tilt angle (step S618). If the tilt angle changes, steps S616 to S618 are repeated. If the tilt angle does not change, the flow advances to step S620 to set the current tilt angle to the tilt up limit TUL. Here, the tilt angle does not change because (1) the display positioning device is no longer mechanically and structurally tilted up, or (2) the display is in contact with a wall and no longer tilts up. Therefore, the tilt angle in this case is set to the tilt up limit. However, in addition to this, the tilt up limit may be set by the user or the tilt up limit may be set by another method.

After that, the tilt motor is rotated forward (step S622), and it is determined whether the tilt angle is 0 degrees (step S624). If the tilt angle is not 0 degrees, steps S622 to S624 are repeated, and when the tilt angle is 0 degrees, the process proceeds to the next step to set the left swivel limit and the right swivel limit.

The body swivel motor is rotated forward (step S626), and it is determined whether there is a change in the body gear angle (step S628). If the body gear angle changes, steps S626 to S628 are repeated. If the body gear angle does not change, the process proceeds to step S630 to set the current body gear angle to the left swivel limit LSL. Here, the case where the body gear angle does not change is because (1) the display positioning device is no longer mechanically and structurally left swivel or (2) the display is no longer left swivel due to contact with the wall. Therefore, the body gear angle in this case is set to the leftward swivel limit. However, in addition to this, the left swivel limit may be set by the user or the left swivel limit may be set by another method.

After that, the body swivel motor is reversely rotated (step S632), and it is determined whether there is a change in the body gear angle (step S634). If the body gear angle changes, steps S632 to S634 are repeated. If the body gear angle does not change, the process proceeds to step S636 to set the current body gear angle to the rightward swivel limit RSL. Here, the case where the body gear angle does not change is because (1) the display positioning device is no longer mechanically and structurally swiveled or (2) the display is in contact with the wall and is no longer swiveled. Therefore, the body gear angle in this case is set to the rightward swivel limit. However, in addition to this, the right swivel limit may be set by the user or the right swivel limit may be set by another method.

The order of setting the tilt down limit, the tilt up limit, the leftward swivel limit and the rightward swivel limit described above may be reversed.

Through the above-described automatic calibration function, it is possible to set the tilt down limit, the tilt up limit, the left swivel limit, and the right swivel limit suitable for the currently installed place and the size of the mounted display.

Further, in the embodiment of the present invention, the display positioning apparatus may include a storage means such as a memory to store the tilt down limit, the tilt up limit, the left swivel limit, and the right swivel limit set by the above-described method. The tilt down limit, tilt up limit, leftward swivel limit, and rightward swivel limit stored in the storage means can be utilized in leftward swivel, rightward swivel, tiltdown, tiltup operation and the like.

7 is a flowchart illustrating a method of performing an auto centering function of a display positioning apparatus according to an embodiment of the present invention. Automatic centering is performed to ensure that the display is minimally spaced from the wall when the user does not use the display or does not want to use the display positioning device.

An input for instructing to perform the automatic center alignment (AC) function is received from the user (step S700). Thereafter, steps S710 and S730 are simultaneously performed.

It is determined whether the arm gear angle S1 and the body gear angle S2 are the same (step S710). If the arm gear angle is smaller than the body gear angle (S1 <S2), rotate the arm swivel motor forward (step S712), and if the arm gear angle is greater than the body gear angle (S1> S2), reverse the arm swivel motor. It rotates (step S714). Here, steps S712 and S714 may drive the body swivel motor in the opposite rotational direction instead of the arm swivel motor. That is, the body swivel motor is reversely rotated in step S712, and the body swivel motor is rotated forward in step S714. The selection of the arm swivel motor or the body swivel motor can be made manually by the user or automatically by the controller of the display positioning device.

If the arm gear angle and the body gear angle are the same (S1 = S2), it is determined whether the tilt angle S3 is 0 degrees (step S716). If the tilt angle is not 0 degrees, step S716 is repeated until 0 degrees.

In step S730, it is determined whether the tilt angle is 0 degrees (step S730). If the tilt angle is less than 0 degrees (S3 <0), the tilt motor is reversed (step S732). If the tilt angle is greater than 0 degrees (S3> 0), the tilt motor is rotated forward (step S734). If it is 0 degree, the tilt motor is stopped (step S736).

When the tilt angle is 0 degrees in step S716, the arm swivel motor and the body swivel motor are rotated in reverse (step S718). It is determined whether the arm gear angle is 0 degrees (step S720), and if the arm gear angle is not 0 degrees, the arm swivel motor is continuously rotated, and when the arm gear angle is 0 degrees, the arm swivel motor is stopped (step S722). ). Then, it is determined whether the body gear angle is 0 degrees (step S724), and if the body gear angle is not 0 degrees, the body swivel motor is continuously rotated, and when the body gear angle is 0 degrees, the body swivel motor is stopped (step S724). S726). Here, steps S718, S720 and S722, and steps S718, S724 and S726 may be performed simultaneously or sequentially.

When the above-described automatic centering function is performed, the display is positioned at the position E1 shown in FIG. 5 after finally completing steps S722 and S726, and the distance from the wall is minimized.

8 is a flowchart illustrating a method of performing a leftward swivel function of a display positioning apparatus according to an embodiment of the present invention. The left swiveling operation refers to the bar shown in FIG. 2.

An input for instructing to perform the leftward swivel function is received from the user (step S800). It is determined whether the current arm gear angle is smaller than 45 degrees (step S802). If the arm gear angle is smaller than 45 degrees, the process proceeds to step S804. If the arm gear angle is smaller than 45 degrees, the process proceeds to step S814.

The left swivel limit may be determined according to the size of the display mounted to the display positioning apparatus as described above.

If the arm gear angle is smaller than 45 degrees, in step S804, the arm swivel motor is driven forward. It is determined whether the body gear angle S2 is smaller than the leftward swivel limit LSL (step S806). If the body gear angle is smaller than the left swivel limit (S2 <LSL), the body swivel motor is driven in reverse rotation (step S808), and if the body gear angle is equal to the left swivel limit (S2 = LSL), the body swivel motor is stopped ( In step S810, when the body gear angle is larger than the leftward swivel limit (S2> LSL), the body swivel motor is driven to forward rotation (step S812). Then return to step S800.

That is, when the arm gear angle is smaller than 45 degrees, the arm is rotated so that the arm gear angle is 45, and the connecting member, the tilt member and the display connected thereto are rotated so that the body gear angle is the leftward swivel limit.

If the arm gear angle is greater than 45 degrees, in step S814, the arm swivel motor is stopped. Then, it is determined whether or not the body gear angle S2 is smaller than the value obtained by adding the leftward margin Δ to the leftward swivel limit (step S816). When the arm gear angle is greater than 45 degrees, the limit that the display can swivel left differs from the left swivel limit set by the method described above in FIG. Therefore, to correct this difference, the left margin Δ is additionally added to the left swivel limit. Here, the leftward margin Δ may be positive, zero or negative, and may vary according to the difference between the arm gear angle and the body gear angle, the size of the display, and the degree of tilt.

When the body gear angle is smaller than the left swivel limit plus left margin (S2 <LSL + Δ), the body swivel motor is driven in reverse rotation (step S818), and if the same (S2 = LSL + Δ), the body swivel motor is stopped. (Step S820), if large (S2> LSL + Δ), the body swivel motor is driven to rotate forward (step S822). Then return to step S800.

Here, the reference value of the arm gear angle may be various values other than 45 degrees as the limit measurement reference when setting the leftward swivel limit in FIG. 6.

9 is a flowchart illustrating a method of performing a rightward swivel function of a display positioning apparatus according to an exemplary embodiment of the present invention. The rightward swivel operation refers to the bar shown in FIG. 3.

An input for instructing to perform a rightward swivel function is received from the user (step S900). It is determined whether the current arm gear angle is smaller than 45 degrees (step S902). If the arm gear angle is smaller than 45 degrees, the process proceeds to step S904. If the arm gear angle is smaller than 45 degrees, the process proceeds to step S914.
