Frame assembly and photovoltaic mechanism

The utility model relates to a frame assembly and a photovoltaic mechanism, the frame assembly comprises a frame unit and a connecting assembly, and the frame unit comprises a first frame strip and a second frame strip. The two opposite side edges of the photovoltaic panel are arranged in the first installation groove and the second installation groove of the frame unit in a penetrating mode respectively. During splicing, all the frame units are arranged mutually, the first mounting strips of every two adjacent frame units are stacked on the second mounting strips, then the first mounting strips and the second mounting strips are locked through the connecting assemblies, and then splicing of every two adjacent frame units is achieved. Due to the fact that the first mounting strips and the second mounting strips are stacked together, the thickness of the splicing positions of the frame units can be increased, the anti-shearing area of the locking positions of the connecting assemblies can be increased, the ant
