The working principle of the present invention is briefly described as follows:

When the elbow support board 2 is folded into the bottom of the desktop board 1, the power switch is turned on, and the control board and the motor 9 are driven to obtain power. Click the "Zoom" button on the operation panel, the high-level signal turns on the relay through the drive control panel, and the DC solenoid valve 4 first receives power to work. When the DC solenoid valve 4 works, the valve stem stretches out under the action of the magnetic force, pushing the M-shaped ejector rod 3 to move downward, and then drives the toggle plate 2 to move vertically downward (the amount of movement is consistent with the thickness of the toggle plate 2). When the toggle plate 2 reaches the moving amount vertically downward, the motor 9 is energized. At this time, the motor 9 works to drive the rotating shaft 8 to rotate, and then drives the second connecting rod 11 to form the assembly end of the second connecting rod 11 and the rotating shaft 8. The origin rotates, and then drives the first connecting rod 10 to act and pull the toggle support plate 2 to move backward until the toggle support plate 2 is located at the bottom of the table top 1 (as shown in FIG. 2 ). The length of time for the motor 9 to receive power is set by the program to be consistent with the time when the toggle plate 2 is pulled into the bottom of the tabletop 1. After the toggle plate 2 is pulled into the bottom of the tabletop 1, the motor 9 stops working; at the same time, the DC solenoid valve 4 works The power is also turned off.

When the toggle support 2 is pushed out to the front side of the desktop 1, the power switch is turned on to drive the control board and the motor 9 to obtain power. Click the "extend" button on the operation panel, the high-level signal will turn on the relay through the driving control board, the motor 9 will be powered first, and drive the rotating shaft 8 to rotate in the opposite direction, and then drive the second connecting rod 11 to connect with the second connecting rod 11 The assembly end of the rotating shaft 8 rotates in the opposite direction to the origin, and then drives the first connecting rod 10 to move to push the toggle support plate 2 to move forward to the set position, and the motor 9 stops working. When the motor 9 stops working, the DC solenoid valve 4 obtains a reverse current, the valve stem retracts under the action of the magnetic force, the M-shaped ejector rod 3 moves upward, and then pushes the toggle plate 2 to move vertically upwards (the amount of movement is the same as that of the toggle plate 2 The same thickness) until the toggle plate 2 is flush with the desktop plate 1 (as shown in Figure 1).

The invention realizes the automatic folding and storage of the table board of the study table, reduces the space occupied by the study table when it is not in use, and is beneficial to the rational use of the space; moreover, the use of button electric control ensures the safety of young children when they operate alone sex.
