Automatic-rise-fall computer display device bracket

Abstract

The invention relates to an automatic-rise-fall computer display device bracket which comprises a support unit, a lifting device, a control unit and a power supply unit, wherein the lifting device is arranged in the support unit; the control unit comprises a position detection circuit and a singlechip for controlling the lifting device to rise and fall; the power supply unit is connected with the control unit and lifting device; the position detection circuit comprises a U-shaped resistor and two position sensing elastic needles; the U-shaped resistor is fixed to the support unit; the position sensing elastic needles are fixed to the lifting device; and the two position sensing elastic needles communicate with each other and are movably connected with both ends of the U-shaped resistor. By adopting the singlechip and position detection circuit to control the rise and fall process, the rise and fall distance can be accurately controlled, and the rise and fall stop time can be accurately controlled; and the rise or fall speed can be accurately changed by changing the transmission ratio of the worm and gear.

Description

technical field [0001] The invention relates to the technical field of automatic control lifting, in particular to an automatic lifting computer monitor support. Background technique [0002] With the popularization of computers, more and more people use computers to work, and problems arise. When people operate computers or use computers to read, they often maintain a posture for a long time, and the viewing angle is generally fixed in one direction. It is easy to cause visual fatigue and other eye diseases; and maintaining a posture for a long time is easy to cause cervical spondylosis, frozen shoulder, etc. According to statistics, more than 90% of white-collar workers suffer from mild or severe cervical spondylosis. The main reason is that they have been in a single fixed posture for a long time. And present conventional monitor is fixed, and this has caused people's line of sight to be fixed at an angle for a long time, therefore, can only maintain a posture when readi...

AI Technical Summary

Problems solved by technology

[0003] 1. It is impossible to accurately control the distance of ascent and descent, and the speed of ascent and descent cannot be adjusted;

[0004] 2. The time of rising, falling and stopping cannot be precisely controlled;

[0005] 3. Cannot operate continuously

Although the disclosed utility model patent can achieve automatic control of rising and falling, it cannot accurately control the distance of rising and falling, and cannot adjust the speed of rising and falling; nor can it control the time of rising, falling and stopping; it cannot operate continuously
