Abstract
A rotating shaft device, an electronic device and a control method thereof are provided according to the present application. The rotating shaft device includes a driving component and a rotating component. The driving component is configured to receive a control signal, and adjust a torsion force of the rotating component based on the control signal. In the case that the rotating shaft device is applied on the electronic device, various control signals may be provided to control the driving component to adjust a torsion force of the rotating component by the controller, such that the torsion force of the electronic device in a folding or unfolding process is smaller than the torsion force of the electronic device in a state being maintained, which solves the issue of poor user experience resulted from being difficult to fold or unfold and inconvenient to operate.
