A plate folding and unfolding device and a solar panel structure are provided. The plate folding and unfolding device includes a cam (120,220,320) fixed with first plate piece (111,211), and a rotating shaft (130,230,330) is disposed inside the cam (120,220,320) in an axial direction of the cam; a connecting rod (140,240,340), where the connecting rod (140,240,340) includes a first end and a second end that are opposite to each other, the first end is connected vertically to the rotating shaft (130,230,330), and the second end is fixed to a second plate piece (112,212), so that the second plate piece (112,212) and the first plate piece (111,211) fold or unfold around the rotating shaft (130,230,330); a positioning shaft (150,250,350), where the positioning shaft (150,250,350) is disposed, parallel to the rotating shaft (130,230,330), on the connecting rod (140,240,340), and the positioning shaft (150,250,350) rotates along with the connecting rod (140,240,340) and can move back and forth in a radial direction of the cam (120,220,320); and an elastic piece (160,260,360), where the elastic piece (160,260,360) is disposed on the connecting rod (140,240,340), one end of the elastic piece is connected to the positioning shaft (150,250,350), so that the positioning shaft (150,250,350) fits closely to an outer peripheral surface of the cam (120,220,320), where a groove (122,222,322) that accommodates the positioning shaft (150,250,350) is disposed at at least one location of the outer peripheral surface of the cam (120,220,320). The plate folding and unfolding device and the solar panel structure make locking of two connected plate pieces at a predetermined angle much easier at a more accurate location. In addition, the design is simplified and costs are reduced.
