FIG. 3 is a view showing a module for raising and lowering the monitor raising and lowering apparatus capable of controlling a plurality of batch modes according to an embodiment of the present invention.

Hereinafter, the ascent / descent module 300 of the present embodiment will be described with reference to FIG.

3, the lifting / lowering module 300 includes a fixing member 310 fixed to the table 100, a moving member 320 movable up and down with respect to the fixing member 310, And a lifting and lowering driving unit 330 for lifting the member 320 up and down.

The fixing member 310 may include a guide 312 arranged in the upward and downward directions. The moving member 320 is slidably coupled to the guide 312 and is movable upward and downward along the guide 312.

In this embodiment, the guide 312 may be provided with a < RTI ID = 0.0 > The shifting member 320 may be provided with a pinion gear that rotates in engagement with the gear provided on the side as the shifting member 320 moves upward and downward along the guide 312. Thus, the movable member 320 can be prevented from being wobbled when the movable member 320 is lifted or lowered, thereby driving the movable member 320 more stably.

3, the lifting and lowering driving unit 330 may include a motor 331, a driving pulley 332, a driven pulley 333, and a belt 334.

The motor 331 can rotate in the forward direction or the reverse direction.

The drive pulley 332 is connected to the rotation shaft of the motor 331 and can rotate together with the rotation of the motor 331. [ The driven pulley 333 can be connected to the driven pulley 332 by a belt 334 and the rotation of the driven pulley 332 can be transmitted to the driven pulley 333 by the belt 334. [

The moving member 320 is mechanically coupled to one side of the belt and can move upward and downward as the belt 334 moves. The drive pulley 332 and the driven pulley 333 may be arranged vertically so that the moving member 320 moves in the up and down directions.

A worm gear may be provided between the motor 331 and the drive pulley 332 to transmit the rotation of the motor 331 to the drive pulley 332 at a large reduction ratio.

The manual lifting and lowering module 300 may further include a manual handle 335 capable of manually rotating the driving pulley 332 in case the power is not applied to the motor 331 due to a power failure or a failure .

The structure of the lifting / lowering module 300 described above is merely an example, and can be variously configured in any way as long as the movable member 320 can be moved up and down with respect to the fixing member 310.

Hereinafter, the operation of the lifting and lowering driving unit 330 will be described.

The motor 331 can be rotated in the forward direction by the application of electric power or the input of the user.

The rotation of the motor 331 is decelerated by the worm gear at a large reduction ratio and is transmitted to the drive pulley 332. As the drive pulley 332 rotates, the belt 334 which is in contact with the drive pulley 332 also rotates . The rotation of the drive pulley 332 can be transmitted to the driven pulley 333 by the movement of the belt 334. [

As the belt 334 moves, the moving member 320 coupled to one side of the belt 334 can move up and down. Thus, the pinion gear provided on the moving member 320 can move along the guide The movable member 320 can be stably lifted and lowered while being rotated by engaging with the rack gear provided on the movable member 320.

Conversely, when the motor 331 rotates in the opposite direction, the driving pulley 332, the belt 334, the driven pulley 333, and the like that rotate together by the motor 331 also rotate in the opposite direction, .

The link module 400 includes a first link driving unit 410 and a first link driving unit 410 that independently rotate the link module 400 relative to the moving member 320, And a second link driver 420 for relatively rotating the first link 200.

The first link driving unit 410 includes a first rotating shaft 411 and a second rotating shaft 411 which are provided on the rotating shaft of the link module 400 and the moving member 320 and are coupled to the moving member 320 to rotate the moving member 320, And a first driving motor 412 for rotating the rotary shaft 411 in the forward and reverse directions. The first link driving part 410 may include a first gear set 413 for transmitting the rotation of the first driving motor 412 to the first rotation shaft 411.

In order for the link module 400 to rotate with respect to the moving member 320, the first rotating shaft 411 may be positioned above the upper plate of the table 100.

Therefore, the rotation of the first drive motor 412 can be transmitted to the first rotation shaft 411 by the first gear set 413. The link member 400 coupled to the first rotation shaft 411 is rotatably coupled to the link member 400 so that the link member 400 is rotatably coupled to the movable member 320 along with the rotation of the first rotation shaft 411, The movable member 320 can be rotated relative to the movable member 320 by a predetermined angle.

The rotation angle of the first link driving part 410 may be limited until the link module 400 comes into contact with the table 100, that is, about 90 degrees.

The second link driving unit 420 includes a second rotation axis 421 and a second rotation axis 422 which are provided on the rotation axis of the link module 400 and the monitor 200 and are coupled to the monitor 200 to rotate the monitor 200, And a second driving motor 422 for rotating the first driving motor 421 in the forward and reverse directions. The second link driver 420 may include a second gear set 423 that transmits the rotation of the second drive motor 422 to the second rotation shaft 421.

The rotation of the second driving motor 422 is transmitted to the second rotation shaft 421 by the second gear set 423 and the rotation of the second rotation shaft 421 causes the monitor 200 to rotate the link module 400 ) Relative to each other.

That is, the angle of the monitor 200 can be adjusted by the relative rotation of the link module 400 and the monitor 200 by the first link driver 410 and the second link driver 420.

Here, the link module 400 can be operated after the movable member 320 is completely lifted and the operation of the lifting / lowering module 300 is completed.

The angle of the monitor 200 can be adjusted by the link module 400 so that the angle of the monitor 200 can be adjusted according to the user's physical condition or usage environment.

The control module 500 controls the up and down driving unit 330, the first link driving unit 410, and the second link driving unit 400 according to a plurality of arrangement modes according to relative angles of the monitor 200, the link module 400, The operation of the second link driver 420 can be controlled.

For example, the control module 500 may store three modes.

Hereinafter, the control and operation of the monitor raising / lowering apparatus capable of controlling a plurality of arrangement modes of this embodiment will be described with reference to the drawings.

FIG. 5 is a view showing a state before operation of the monitor ascending / descending apparatus capable of controlling a plurality of batch modes according to an embodiment of the present invention, and FIG. 6 is a view illustrating a state in which a plurality of batch mode control capable monitors And the first mode of the ascending / descending device.

6, the monitor 200 is positioned above the top plate 100 of the table 100 through the opening 110 of the table 100 by the moving member 320, The controller 400 can set the state in which it is located in the table 100 to the first mode.

5, when the first mode is selected, the control unit rotates the motor 331 in the forward direction so that the drive pulley 332, the belt 334 and the driven pulley 333 are rotated, The moving member 320 coupled to one side of the belt 334 can move up with the movement of the moving member 334. Accordingly, the pinion gear provided on the movable member 320 is engaged with the rack gear provided on the guide 312 to rotate the movable member 320 in a stable manner. The motor 331 can raise the movable member 320 only when the monitor 200 is positioned above the upper plate of the table 100 and the link module 400 is placed in the table 100 .

7 is a diagram illustrating a second mode of the monitor raising / lowering device capable of controlling a plurality of arrangement modes according to an embodiment of the present invention.

2, the monitor 200 is moved up through the opening 110 of the table 100 by the moving member 320 and the link module 400 is moved up and down with respect to the moving member 320 The monitor 200 rotates about 45 degrees in a direction in which the user is positioned and the monitor 200 can set the second mode in which the link module 400 is rotated about 90 degrees in the direction opposite to the direction in which the link module 400 is rotated have.

When the second mode is selected, the controller moves the moving member 320 up as the first mode, until the monitor 200 and the link module 400 are all above the upper plate of the table 100, (320) can be maximally raised. The first drive motor 412 rotates the first rotation shaft 411 in the direction in which the user is positioned and the link module 400 is rotated by the rotation of the first rotation shaft 411, The first rotating shaft 411 and the second rotating shaft 411 can be rotated relative to each other. The second driving motor 422 rotates the second rotating shaft 421 in the direction opposite to the first rotating shaft 411 independently of the first driving motor 412 and rotates the second rotating shaft 421 The monitor 200 can rotate about 90 degrees.

8 is a diagram illustrating a third mode of the monitor raising / lowering apparatus capable of controlling a plurality of arrangement modes according to an embodiment of the present invention.

If the third mode is selected, the control unit can raise the movable member 320 as much as the second mode. The first driving motor 412 rotates the first rotation shaft 411 about 90 degrees in a direction in which the user is positioned so that the link module 400 coupled to the first rotation shaft 411 contacts the upper plate of the table 100 . The second driving motor 422 rotates the second rotating shaft 421 in the direction opposite to the rotating shaft 411 independently of the first driving motor 412 and rotates the second rotating shaft 421 by the rotation of the second rotating shaft 421 200) can rotate about 120 degrees.

Therefore, in general, a first mode is used, a user with a large key can use the second mode, and a user with a poor eye can use the third mode. In addition, the mode can be adjusted so that the light is not reflected by the user's eyes or the monitor 200 is not reflected according to the angle at which the light is incident on the monitor 200.

The control module 500 may control the operations of the up / down driving unit 330, the first link driving unit 410, and the second link driving unit 420 according to the value input by the user. Therefore, the angle and position of the monitor 200 can be finely adjusted according to the user's convenience in addition to the pre-stored value.

In addition, the user may store frequently used values in the first to third modes through fine adjustment.

Accordingly, since the desired value is stored according to the user so that the user can input the mode at any time, the monitor 200 is set as the pre-stored value, thereby providing a user-centered use environment.

For this purpose, an input module 600 for allowing a user to input a mode and perform fine adjustment may be provided. The input device may be connected to the control module 500 so that a value input by the user through the input module 600 may be transmitted to the control module 500.

However, the first to third modes described above are merely examples, and the pre-stored value is a position of the monitor 200 that can be directly stored by the user, and may be stored differently according to the user. In addition, although three modes are stored in the present embodiment, the number of storage modes is not limited thereto, and may be stored more or less as necessary.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
