A certain number of single-chip cells must be sealed into solar cell modules in series and parallel to avoid corrosion of the battery electrodes and interconnects. In addition, the encapsulation also avoids battery breakage. However, the solar cell modules cannot be folded during use, which makes it inconvenient to store and transport the solar cell modules. In order to improve the above-mentioned disadvantages, the patent with application number 202320399910.6 in the public technology has been applied, including an upper fixed frame and a lower fixed frame. The upper fixed frame and the lower fixed frame are the same in size and shape. The solar cell module body is installed in the upper fixed frame and the lower fixed frame. There is a passage between the upper fixed frame and the lower fixed frame. The two sets of connecting mechanisms are connected, and the two sets of connecting mechanisms are symmetrical on the left and right. Although the upper fixing frame and the lower fixing frame can be folded together by setting the connecting mechanism, through the joint action of the card plate, the cross bar, the rotating block, the fixed block and the bolts, so as to facilitate the storage and transportation of the solar cell module body, there are still certain small disadvantages in actual use. For example, during the opening and closing of the two fixing frames to unfold the two solar cell module bodies for use, there is a lack of limiting function between the two fixing frames, and the stability of the two solar cell module bodies during subsequent unfolding and use is poor, which is not convenient for their proper use. In addition, during the folding and storage prevention process, the stability of the upright placement of the fixing frame is poor, and the practical performance is poor. Utility Model Content
