Abstract: A hinge mechanism includes a base, a first rotation component, and a second rotation component, and the first rotation component and the second rotation component are disposed on two sides of the base respectively. The first rotation component includes a first support arm, a first rotation plate, a first pin shaft, and a first torsion spring. The first support arm is rotatably coupled to the base. A first side of the first rotation plate is rotatably coupled to the first support arm via the first pin shaft. The first torsion spring is sleeved on the first pin shaft, a first torsion arm of the first torsion spring is fastened to the first support arm, and a second torsion arm of the first torsion spring abuts against the first side of the first rotation plate.

Abstract: A foldable electronic device and a hinge mechanism thereof are provided. In addition to the hinge mechanism, the electronic device further includes two housings and a flexible display. The two housings are respectively disposed on two opposite sides of the hinge mechanism and are rotatably connected to the hinge mechanism. The hinge mechanism includes a base and a main shaft module. The base includes a bearing surface. The main shaft module includes two rotating assemblies. The two rotating assemblies are disposed on two opposite sides of the base. Each rotating assembly includes a swing arm and a housing fastening bracket, and each housing fastening bracket may be fastened to a housing on a corresponding side. In an unfolded state, the bearing surface independently supports a foldable portion of the flexible display. In a folded state, a screen accommodation space is formed between the two housing fastening brackets and the base.
