[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Combination Figures 1 to 3 Shown:

[0019] A foldable photovoltaic panel comprises a first panel 1, a second panel 2 is arranged on one side of the first panel 1, a third panel 3 is symmetrically arranged at a top corner of the first panel 1 on the side, a fourth panel 4 is arranged at a side of the third panel 3 opposite to the second panel 2, a rotating groove 5 is arranged above the first panel 1 and the second panel 2, a rotating device 6 is arranged at both ends of the rotating groove 5, and fixed blocks 7 are arranged oppositely at the top corners of the first panel 1 and the third panel 3, and a fixed shaft 9 is arranged inside the fixed block 7.

[0020] The same rotating grooves 5 and rotating devices 6 as those on the top of the No. 1 and No. 2 plates are symmetrically arranged below the No. 3 and No. 4 plates 4. The rotating device 6 includes two pairs of fixed ear seats 10 staggered on the No. 1 and No. 2 plates 2. A rotating shaft is arranged in the fixed ear seats 10 for folding the No. 1 and No. 2 plates 2 or the No. 3 and No. 4 plates 4.

[0021] Rotation grooves 8 are provided at the four opposite corners of the No. 1 panel 1, the No. 2 panel 2, the No. 3 panel 3 and the No. 4 panel 4. Fixed blocks 7 are symmetrically arranged in the rotation grooves 8 on the No. 1 panel 1 and the No. 3 panel 3 in an upper and lower staggered manner to facilitate the rotation of the photovoltaic panels. The diameter of the rotation groove 8 is larger than the diameter of the fixing ring to prevent the No. 2 panel and the No. 1 panel from being unable to rotate and stack.

[0022] The fixed block 7 is a spherical crown structure, which is connected to the corresponding plate No. 1 or plate No. 3. A fixing hole is provided at the axial position of the fixed block 7, and a fixing shaft 9 is provided in the fixing hole. An annular fixing groove 71 is provided on the fixed block 7 above the fixing hole, and fixing rings 90 are provided at both upper and lower ends of the fixing shaft for cooperating with the annular fixing groove 71 to fix the block 7 and prevent it from falling out.

[0023] Plate No. 1 1 , plate No. 2 2 , plate No. 3 3 and plate No. 4 4 are all of the same rectangular plate structure, and the symmetrical structure improves the overall regularity.

[0024] Working principle: For the unfolded photovoltaic panel, the No. 1 panel and the No. 3 panel are moved up and down and then rotated to overlap the two panels. In the second step, the No. 2 panel is rotated by the rotating mechanism to be folded with the No. 1 panel, and the No. 4 panel is rotated by the rotating structure to overlap with the No. 3 panel, thus obtaining a four-layer folded photovoltaic panel for easy transportation. The unfolded photovoltaic panel is obtained by the reverse operation as above.
