Abstract

The invention discloses a rotary shaft assembly, electronic equipment and a method for detecting the opening angle of the electronic equipment. The rotary shaft assembly comprises a first rotary shaft and an adjustable capacitor, and the adjustable capacitor is electrically connected with a controller of the electronic equipment and comprises a first pole piece and a second pole piece, wherein the first rotary shaft is used for driving the first pole piece to rotate so that the overlapping area of the first pole piece and the second pole piece can be changed; and the adjustable capacitor outputs different capacitances according to the different overlapping areas, and the controller detects the opening angle of a display end according to the different capacitances. The capacitances output by the adjustable capacitor are changed through the rotary shaft, so that the corresponding relationship of the opening angle of the display end and the capacitances output by the adjustable capacitor is established, the generated capacitances and stored values are compared and subjected to logic computing through the controller where the stored values corresponding to the opening angle of the display end are stored, the stored values corresponding to the capacitances are determined, and finally the opening angle of the display end is determined.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a rotating shaft assembly, electronic equipment and a method for detecting the opening angle of the electronic equipment. Background technique [0002] The working state of the notebook computer is usually associated with the opening angle of the display end of the notebook computer. For example, when the display end of the notebook computer is closed, that is, the angle between the display end and the system end of the notebook computer is 0. At this time, the notebook computer needs to be set to sleep mode. In order to make the notebook computer in a certain working state when the display end is opened at a certain angle, it is necessary to detect the opening angle of the display end. In the prior art, there is a solution for detecting the opening angle of the display terminal. This solution detects the opening angle of the display terminal through the change of the magnetic...
