In this embodiment, the first connecting member 323 is a chain.

[0067] The second motor 31 can drive the connecting rod 2 to rotate 90° around its axis, so that the photovoltaic unit 20 installed on the connecting rod 2 can be positioned horizontally or vertically. When the automatic folding photovoltaic bracket 100 needs to be folded, the second motor 31 drives the connecting rods 2 on all photovoltaic brackets to rotate 90°, so that the photovoltaic unit 20 installed on the connecting rod 2 is perpendicular to the ground, and then the first driving mechanism 200 rotates the first photovoltaic bracket and the third photovoltaic bracket, so that the first photovoltaic bracket and the third photovoltaic bracket are relatively in a folded state.

[0068] In summary, when the first photovoltaic bracket 101, the second photovoltaic bracket 102 and the third photovoltaic bracket 103 move from the unfolded state to the folded state, the first photovoltaic bracket 101 is rotated 180° counterclockwise by the first driving mechanism 200, so that the first column 1001 of the first photovoltaic bracket 101 is side by side with the fourth column 1004. The third photovoltaic bracket 103 is rotated 180° in the same rotation direction by the first driving mechanism 200, so that the sixth column 1006 of the third photovoltaic bracket 103 is in contact with the third column 1003. Thereby, the folding of the first photovoltaic bracket 101, the second photovoltaic bracket 102 and the third photovoltaic bracket 103 is completed. The folding process is convenient and fast, and the space occupied is small. The method of unfolding or folding the odd-numbered photovoltaic brackets of more than three groups can be carried out according to the unfolding or folding method of the above three groups, which will not be repeated here.

[0069] Please refer to Figures 8 to 12 The present invention also discloses a photovoltaic system 10, which includes an automatic folding photovoltaic support 100, multiple groups of photovoltaic units 20 and a third driving mechanism 40.
