Abstract
A desktop monitor stand is a device that supports the weight of a desktop monitor. The statically balanced mechanism within the stand can help the monitor travel to and stop at any different positions, i.e. in a state of static equilibrium at any position. The current statically balanced mechanisms used in the slider-type desktop monitor stands can be classified into two types. The first type integrates a cam and a spring as a statically balanced mechanism for which the cam profile machining could be costly. On the other hand, the second type utilizes a constant-force spring for balancing the weight of the monitor, but the springs must be tailor-made, which costs more. In this paper, a new statically balanced mechanism for slider-type desktop monitor stands is presented. The shown design uses common links and general spring only, which introduces a breakthrough advantage for reducing the manufacturing cost of the monitor stands. Furthermore, the kinematic and force analyses of the proposed design are carried out, and the mechanism dimension is determined via optimization technique. A prototype of the design is made up, and the experimental test in a practical monitor stand is done. As a result, the proposed mechanism can allow the monitor to remain statically balanced at any working position, which proves that the presenting design is practically workable.
