Abstract
The invention relates to a rotation shaft torsion measuring mechanism for a tablet notebook computer, which comprises a rotation bracket, a rotation disc and sensing elements all installed on a mechanical bench. A rotation shaft is pivoted on the top of the upright rotation bracket on the mechanical bench, and the rotation shaft is driven by a motor to rotate. The bottom of the rotation shaft is combined with a bracket body. Corresponding to a tablet notebook computer to be tested, the rotation shaft is equipped with two clamping jaw groups used to clamp the screen of the to-be-tested notebook computer. The rotation disc is used to carry the tablet notebook computer, and each of the sensing elements, installed on parts of the bench, is used to measure the force when the rotation shaft drives the tablet notebook computer to rotate, wherein the parts of the bench correspond to and abut against the two sides of the tablet notebook computer. As a result, the rotation shaft torsion can be figured out through multiplying the force by the distance from each sensing element to the rotation shaft.
