Preferably, the connecting frame is integrally formed by plastic, and the two hinge plates extend in the same direction and are perpendicular to the inner panel, so that the connecting frame is convenient to be matched with the photovoltaic unit. Preferably, each hinge plate is provided with two through holes, the two through holes on the two hinge plates are respectively opposite to each other, and the hinge shafts at the two ends of the same tangent cylinder and the two through holes opposite to the same tangent cylinder are inserted into each other to form a revolute pair, so that the relative freedom degree of the photovoltaic unit is limited. Preferably, the outer side surfaces of the two tangent cylinders are always contacted when the photovoltaic units rotate relative to the connecting frame, so that the rotation synchronism of the two photovoltaic units can be better maintained. Preferably, two corners of the hinge plate away from the inner panel are rounded to reduce interference with movement of the movable member. Preferably, the photovoltaic unit comprises a rectangular photovoltaic panel core, and the outer side of the photovoltaic panel core is wrapped with a protective frame for reducing impact damage to the edge of the photovoltaic panel core. Preferably, the baffle plate and the tangent cylinder are positioned on the same side of the protective frame and are of an integrated structure, and are made of aluminum alloy materials, so that the light-weight high strength is achieved.
