[0049] Working principle: The working principle of a linear-driven intelligent learning lift table of the present invention mainly revolves around a control component, a table leg lifting device and a rotary lifting device to realize linear lifting and rotation of the desktop and height adjustment of the table legs. When using this device, the control component controller 11, a lifting motor isolation cover 12, a power supply 13 and a rotary motor 14 are composed of the control component controller 11, which is responsible for receiving instructions from the control button 6 and controlling the operating status of the lifting motor 15 and the rotary motor 14 according to the instructions. When the user presses the control button 6, the instruction signal is transmitted to the controller 11. After the controller 11 parses the instruction, it sends a control signal to the lifting motor 15 and the rotary motor 14 through the connecting line. The lifting motor 15 and the rotary motor 14 perform corresponding rotational movements according to the received control signal, thereby driving the lifting and rotation of the desktop. The control component receives instructions from the control button 6 and controls the operating status of the lifting motor 15 and the rotary motor 14 accordingly, thereby realizing intelligent lifting of the desktop. This control method allows users to easily adjust the height and angle of the desktop according to personal needs, thereby improving the convenience and comfort of use.

[0050] The table leg lifting device is composed of a lifting motor 15, a gear box 16 and a lifting threaded rod 27, which is responsible for controlling the lifting of the table leg 2. The lifting motor 15 is fixed on the inner wall of the device installation box 1, and its rotating shaft is fixedly connected to the gear box 16. When the lifting motor 15 receives the control signal of the controller 11, it starts to rotate and drives the gear box 16. The gear box 16 converts the rotary motion of the lifting motor 15 into the linear lifting motion of the lifting threaded rod 27. The lower end of the lifting threaded rod 27 is threadedly connected to the lifting support leg 26 and is connected to the inner wall of the bottom side of the table leg 2 by rotation. When the lifting threaded rod 27 is linearly lifted, it will drive the lifting support leg 26 and the table leg 2 to lift together, thereby realizing the adjustment of the height of the table leg. The stable lifting of the table leg is realized through mechanical transmission, so that the desktop remains stable during the lifting process, avoiding shaking and noise.

[0051] When the second desktop 5 needs to be raised for reading, when the rotating motor 14 receives the control signal of the controller 11, since the rotating shaft of the rotating motor 14 is fixedly connected with the gear 18, the gear 18 is meshed with the gear 20, and the rotating motor 14 starts to rotate and drive the gear 20. The rotation of the gear 20 drives the threaded rod 19 to rotate on both sides of the support frame 17. The side of the threaded rod 19 is threaded with a mobile extrusion block 21 in the inner cavity of the corresponding support frame 17. When the threaded rod 19 rotates, the mobile extrusion block 21 will perform a linear lifting movement along the threaded rod 19 under the action of the thread. The lifting and lowering of the mobile extrusion block 21 will support or release one end of the second desktop 5, thereby realizing the arc lifting and lowering of the second desktop 5. The rotating lifting device enables the second desktop to be lifted and rotated in an arc, which increases the flexibility of the desktop. The user can adjust the angle and height of the desktop as needed to adapt to different learning and working postures, and by adjusting the angle and height of the desktop, it can effectively alleviate the discomfort of the neck, back and other physical discomforts caused by maintaining the same posture for a long time, and improve the comfort and health of learning and working.
