[0002] With the rapid development of photovoltaic power generation technology, photovoltaic (PV) mounting systems, as the core structure supporting PV modules, have received widespread attention for their functionality, stability, and installation efficiency. Currently, traditional fixed PV mounting systems are gradually evolving towards adjustable and foldable designs to adapt to the installation needs of different scenarios. In existing technologies, single-axis tracking mounting systems improve power generation efficiency by adjusting the tilt angle, but their structure is complex and costly; seasonally adjustable mounting systems use bolts to fix the angle, which improves adaptability, but the operation is cumbersome and cannot achieve rapid folding.

[0003] Existing folding photovoltaic brackets generally have the following shortcomings: First, the compatibility between the folding mechanism and the ground connection is poor, which makes it easy for interference or positioning deviation to occur during the unfolding process. The ground adapter of the folding bracket lacks a receiving slot design, and manual calibration is required after unfolding. Second, the connection method between the support frame and the bracket is simple, making it difficult to meet the requirements of quick disassembly and high rigidity.

[0024] The ground connecting frame 7 has a first mounting hole 73. The ground connecting frame 7 is connected to the cement foundation by expansion bolts 8. The vertical support frame 6 is connected to the ground connecting frame 7 by long bolts 11. The end of the support frame 4 is welded with a cover plate 2.

[0025] The slider device 5 includes a slider body 51, which is connected to a fixing block 54 via an arc-shaped connecting plate 55. The fixing block 54 is fixedly connected to the elastic pin device 9. A heightening block 56 is fixedly connected to the upper part of the slider body 51, and the heightening block 56 is connected to the connecting ear of the photovoltaic panel 1 via a first bolt.

[0026] Anti-detachment blocks 53 are fixedly connected to the left and right sides of the slider body 51, and an anti-detachment groove 44 is provided on the front side of the support frame 4. The slider body 51 is connected to the threaded hole 42 on the left side of the support frame 4 by the second bolt 52.

[0027] The upper part of the vertical support frame 6 is provided with a connector 61, and the lower part of the support frame 4 is welded with a top connecting plate 41. The connector 61 is connected to the top connecting plate 41 through the second rotating shaft 10.

[0029] Working principle: When the bracket is in the folded storage state, the support frame 4 rotates downward around the first pivot 3, and its lower half is embedded in the first groove 72 of the ground connecting frame 7, forming a spatial constraint through the side wall of the groove; the vertical support frame 6 folds around the second pivot 10 toward the ground connecting frame 7, and its end passes through the clearance notch 71 and fits against the support frame 4.
