The invention provides a folding hinge structure. The folding hinge structure comprises a base assembly, a connecting plate assembly rotationally connected with the base assembly, a connecting swing rod assembly rotationally or slidably connected with the base assembly and the connecting plate assembly, and a damping assembly. A first cam is fixed to the first connecting swing rod, a second cam is fixed to the second connecting swing rod, and the first cam and the second cam are located on the same side of the connecting swing rod assembly. The opposite surfaces of the first cam and the third cam are respectively provided with a bulge and a notch which are meshed with each other; the opposite surfaces of the second cam and the fourth cam are respectively provided with a bulge and a notch which are meshed with each other; the elastic driving assembly is used for providing elastic driving force so that the first cam and the third cam can get close to each other in the length direction of the base assembly, and
