The rotating shaft is covered with an inclination gear 46. The inclination gear cooperates with another gear 47 and is driven by an inclination motor to adjust the depression angle of the display. It is connected with the rotating motor to realize the horizontal rotation of the rotating disc, the rotating disc 42 is connected with the bracket 41, and the bottom of the bracket 41 is connected with the lifting motor to realize the lifting of the whole device. Described lifting motor 45 realizes bracket and whole device up and down by screw rod 450 assembling nut structure, and lifting motor is lowered to lowest position and adjusts inclination motor to make display be positioned at below desktop and cover cover plate at window place. Described inclination motor 43, rotating motor 44 and lifting motor 45 are all stepper motors, and each motor is controlled by a micro-controller single-chip microcomputer to realize display lifting or rotation or adjustment of depression angle, and the limit position of display lifting or rotation or depression angle is provided with Proximity switch.

Please refer to Fig. 1 and Fig. 2, the drawing board 3 of the present invention is made up of a transparent board and a frame in the middle, the light source under the transparent board is an LED light source, and a clip bar 32 is provided near the bottom edge of the drawing board to prevent it from being tilted when it is in a tilted state. Objects slide down. There are table legs 21 under the described table frame 2, and the table legs are the table legs of the self-locking lifting structure of the screw to realize the overall lifting of the table. The table frame below the drawing board is provided with a drawer 33, and the table frame in the computer area is provided with a keyboard long supporting plate, which is connected to the table frame by a hinge and can be folded in front of the table frame to form a baffle plate or to be laid flat. to place the keyboard.

The display of the present invention can realize 360° rotation and 0-90° tilt angle swing after being raised to the desktop.

1) The lifting mechanism of the table legs (as shown in Figure 2)

In order to adapt to different groups of people and adjust everyone's sitting posture to the best, the table corners are specially designed to have the function of lifting. The working principle of the lifting mechanism of the table leg: the lifting function of the table corner is realized by the cooperation of the nut and screw with self-locking function. By rotating the screw that is fixed relative to the position, the part that is rigidly connected to the nut is lifted; to achieve The overall lift of the table. The whole movement process is smooth and the self-locking performance is good.

2) The lifting mechanism, inclination and rotation mechanism of the display (as shown in Figure 1 and Figure 2)

On the one hand, in order to make the desktop more tidy and beautiful; on the other hand, in order to adapt to different angles of sitting and viewing the screen, the purpose of humanization has been achieved. The lifting mechanism, inclination and rotation mechanism of the display are designed ingeniously.

Working principle of lifting mechanism, tilting angle and rotating mechanism: The lifting mechanism, tilting angle and rotating mechanism of the display pass through the control panel after adjusting the lifting, tilting angle, and rotating speed of the display of the single-chip program. When not in use, the entire screen is under the desktop. When it is necessary to use it, the board on it is removed, and the screen is lifted to a predetermined height with the desktop by the button under the action of the stepping motor, and then it contacts with the travel switch to stop the motion. Then use the stepper motor to control the rotation of the screen at any angle, which can be rotated 360°, and finally control the inclination angle of the screen, the inclination angle can reach up to 90° (after reaching this angle, it will contact the travel switch and stop moving). When the screen is adjusted to the best state for people, it will no longer swing freely due to the self-locking function of the stepping motor. When the screen is not in use, it can be lowered below the table according to the steps in the rising direction. The entire desktop appears tidy and the usable space is thus greatly improved.

The lifting of the display is realized by a screw nut mechanism. The nut is fixedly connected with the lifting frame (bracket) on which the display is placed, and the screw rod is fixedly connected with the stepping motor. With the positive and negative rotation of the stepping motor, the screw rod and the nut are driven to rotate relative to the lifting frame to lift. The screw nut mechanism has a large load when the speed is medium and low, and the movement is stable and the noise is small. In addition, the self-locking performance of the screw nut is good, which can prevent the motor from losing the self-locking function after power failure, and has high safety.

3) Adjustable inclination mechanism of the drawing board

In order for people to read books or draw pictures, a drawing board module is specially added. This module designs the middle of the drawing board as light-transmitting glass, and the desktop has a built-in LED light. When used at night, reading a book or drawing a picture through the soft light can make people feel more energetic, and it is beneficial to protect the eyes, and it can prevent people from being in a normal environment. Hunchback from reading for a long time on the desk. And the inclination angle of the drawing board can be adjusted arbitrarily from 0 to 45° to meet the different needs of people.

The microcontroller of the present invention is a single-chip microcomputer, and the control signal is input through the keyboard to realize the required motion control and better realize the man-machine dialogue. The motor adopts a stepping motor and its matching motor driver. The stepper motor can calculate the number of steps according to the specified length according to the algorithm and perform more accurate forward or reverse rotation, and transmit the power from the motor to the actuator (lifting and turning mechanism) through the power transmission system to control the lifting and turning mechanism exercise. During the movement of the mechanism, in order to prevent the occurrence of roof fall accidents, we use a proximity switch to control its stop point, and pass the feedback signal of the proximity switch to the microcontroller to control the rotation of the motor to prevent the occurrence of roof fall accidents.

Compared with the desks on the existing market, the multifunctional desk of the present invention has the following beneficial effects:

1. Breaking through the tradition - adding mechatronics technology to the traditional desk;

2. Mechanism design - the use of screw transmission mechanism and gear power transmission mechanism greatly improves the stability of transmission and makes the space layout more compact;

3. Ergonomics - by controlling the height of the desktop, the inclination of the desktop and the spatial position of the display, the user can maintain a correct sitting posture, a normal viewing distance and improve the comfort of the office;

4. Display—Single-chip microcomputer intelligently controls the three-dimensional movement of the display;

5. Keyboard - Flip and slide left and right of the keyboard to hide and use the keyboard;

6. Lifting of the table - through the screw drive to realize the raising and lowering of the table;

7. Simple operation - humanized design, users only need to press a few buttons to realize various operations on the display;

8. Easy maintenance - using standardized parts, good interchangeability.
