Abstract: A thinned hinge includes a rotating part and a torsion supply part. The rotating part includes a base and two movable members arranged on the base, the base includes two tracks for the movable members to displace along arc-shaped trajectories to generate opening and closing actions, and ends of the two movable members where extend outward from the two tracks are provided with driving members. The torsion supply part supplies torsion required by the rotating part, the torsion supply part includes a support, two rotating shafts arranged in parallel on the support, and an idle gear arranged between the two rotating shafts, the two rotating shafts are provided with connecting pieces assembled with the driving members to enable the torsion supply part and the rotating part to simultaneously act and gears engaged with the idle gear, and the gears and the idle gear are crossed helical gear structures.
