Supporting module

A supporting module for a display device, the supporting module comprising:

• a fixing seat, having a guide structure, wherein the guide structure defines a linear path;
• a pivot lever, having a shaft and an arm, wherein (i) the shaft is rotatably connected to the fixing seat and has a central axis parallel to the linear path, (ii) the arm is connected to the shaft and used for mounting the display device, and (iii) the arm is configured to be pivotable about the central axis of the shaft and capable of bringing the shaft into synchronous rotary motion;
• a slider, being sleeved on the shaft, wherein (i) the slider and the shaft constitute a screw transmission mechanism with a varied helix angle, (ii) the slider is brought into linear movement along the linear path with respect to the shaft when the arm is forced to induce rotary motion of the shaft, and (iii) the linear movement of the slider depends on axial displacement corresponding to the varied helix angle;
• and
• a spring, having a mobile end and an immobile end, wherein the mobile end is movable with the slider, and the mobile end moves with the slider and the immobile end keeps stationary when the slider moves along the linear path, so that the displacement of the slider causes different degrees of deformation of the spring, resulting in different spring resilience forces on the slider, and the different spring resilience forces are further converted into different resistance torques through the screw transmission mechanism so as to stop the display device at any desired height.
