Technical Field

[0036] The working principle of this utility model is as follows: The lifting monitor bracket is fixed to the table by a fixing base.

[0037] After power is connected, the power switch is used to power the control circuit board. The relevant program and trigger principle of the infrared human body sensor switch are then set through the MCU chip. The MCU chip controls the forward and reverse rotation or running time of the servo motor by controlling the MOSFET module. The MCU chip detects the working current of the servo motor (for example, when the servo motor is rotating forward and descending, the normal power supply is 5V 0.5-0.8A. When we detect the current rising rapidly to 1.5A, the MCU chip will control the servo motor to stop working after it stalls and record this position as the mechanical origin) to determine the upper and lower mechanical origin of the lifting monitor bracket, that is, the maximum travel of the lifting monitor bracket. The control circuit board allows users to move their heads 5-6 times per hour without being aware of it without affecting their work, which can better prevent the damage to the cervical and lumbar spine caused by prolonged sitting. When the infrared human body sensor switch does not detect human activity for several minutes, it will stop lifting and enter standby mode. It will restart lifting when human activity is detected again.

[0038] This invention features an adjustable structure to customize the size of the fixed connector, facilitating rapid installation and significantly improving efficiency. A lifting mechanism with a column, lead screw assembly, drive assembly, and control circuit board enables automatic lifting. The control circuit board incorporates an infrared sensor, an MCU chip, and a MOS module. The infrared sensor acts as an infrared human body induction switch, while the MCU chip controls, processes data, and performs timing functions, allowing for timed control of the lifting mechanism and providing intermittent neck and lumbar spine exercises. The MOS module controls the forward and reverse rotation of the servo motor, providing feedback. A folding mechanism adjusts the distance between the mounting frame and the user, allowing for adjustments to the display's distance and angle, enhancing usability.
