[0073] Furthermore, the second movable link 420 is disposed at a diagonal position of the base plate 300 with the lead screw 530 as the center. As described above, one side end 421 of the second movable link 420 is rotatably fastened to the second movable link fastening portion 320 provided on the base plate 300, and the other side end 422 is rotatably fastened to the second movable fastening portion 551, and moves in accordance with the linear movement of the second movable portion 550.

[0074] One side end 431 of the first supporting link 430 is rotatably fastened to the first sliding portion 350, and the first sliding portion 350 is inserted into the first guide slot 330 formed in the bottom plate 300 and slides, and the other side end 432 is rotatably fastened to the first supporting link fastening portion 111, and the first supporting link fastening portion 111 is fastened to the housing. In addition, the center of the first supporting link 430 is fastened to the center of the first movable link 410 via the first hinge portion 451 in a relatively rotatable manner.

[0075] Furthermore, one side end 441 of the second supporting link 440 is rotatably fastened to the second sliding portion 360, the second sliding portion 360 is inserted into the second guide slot 340 formed in the bottom plate 300 and slides, and the other side end 442 is rotatably fastened to the second supporting link fastening portion 112, the second supporting link fastening portion 112 being fastened to the housing. Furthermore, the center of the second supporting link 440 is fastened to the center of the second movable link 420 via a second hinge portion 452 in a relatively rotatable manner.

[0076] With this structure, when the first moving part 540 and the second moving part move linearly along the lead screw 530, the first movable link 410 and the first supporting link 430 rotate relatively around the first hinge part 451, and the second movable link 420 and the second supporting link 440 rotate relatively around the second hinge part 452. At this time, in response to the rotation of the first supporting link 430 and the second supporting link 440, the first sliding part 350 and the second sliding part 360 move linearly in opposite directions along the first guide slit 330 and the second guide slit 340 to move the bottom plate 300 up and down.

[0077] As described above, the present invention has a pair of movable links 410, 420 and supporting links 430, 440, respectively, which can support the four corner areas of the base plate 300 and lift them, thereby being able to stably move the base plate 300 without shaking.

Here, the PWM control unit is configured to be connected to the movable unit 500 via wire or wirelessly to transmit a command signal for controlling the drive motor 510.

[0086] With this structure, when the user rotates the knob, the base plate 300 can be controlled to rise or fall in accordance with the direction of rotation. Furthermore, when the knob is rotated to adjust the rotation angle of the knob, at least one of the moving speed and the moving height of the base plate 300 can be controlled by PWM control accordingly.

[0087] That is, the user can adjust the motor duty according to the rotation position of the knob, thereby adjusting the rotation speed of the motor to set the moving speed of the base plate 300. In addition, the rotation speed of the motor can be adjusted according to the rotation position of the knob to set the moving height of the base plate 300. Although not shown separately, the command input for setting the moving speed or moving height of the base plate 300 can be changed by touching or pressing the knob.

[0088] As another example, the control unit 600 can also be configured as a touch panel. Here, it can be configured such that a command button is displayed on the touch panel, and the user operates the command button to control at least one of the moving direction, moving speed, and moving height of the base plate 300. Here, it can be configured such that the touch panel is connected to the movable unit 500 via wire or wirelessly and transmits a command signal for controlling the drive motor 510.

[0089] The touch panel is provided with command buttons for adjusting the moving speed and moving height of the base plate 300, so that the user can touch these command buttons to adjust. In addition, it can be configured so that numbers indicating the moving speed and moving height are displayed in the center of the button. Of course, the state displayed on the touch panel is equivalent to an example, and it can be configured so that the user can input commands in various forms.

[0090] As another example, the control unit 600 may be provided as a switch, that is, the control unit 600 may be configured to control at least one of the moving direction, moving speed, and moving height of the base plate 300 in accordance with the operation of the switch.

[0091] As an example, the bottom plate 300 can be controlled to rise when the front of the switch is pressed, and to fall when the back of the switch is pressed. Here, the bottom plate 300 can also be controlled to move at a height corresponding to the time the switch is pressed, and to move at a speed corresponding to the pressure with which the switch is pressed.

[0092] As described above, the electric cup holder 100 according to the embodiment of the present invention includes the control unit 600 capable of adjusting the moving speed and moving height of the bottom plate 300 on which the container 10 is placed, thereby improving the convenience of use.
