An electronic device includes a first body, a second body, a hinge structure and a control unit. The hinge structure includes a first pivot component fixed on the first body, a second pivot component fixed on the second body and pivoted to the first pivot component, a first connecting component fixed on the first pivot component, and a torsion adjusting assembly movably disposed at the second body. The control unit receives a command to control the torsion adjusting assembly to move. When the torsion adjusting assembly is moved to a first position, the first connecting component and the torsion adjusting assembly are separated from each other, and the hinge structure has a first torsion. When the torsion adjusting assembly is moved to a second position, the first connecting component is connected to the torsion adjusting assembly, and the hinge structure has a second torsion larger than the first torsion.
