Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic solar brackets, and in particular to a deformable photovoltaic solar bracket. Background Art

[0002] When using outdoor portable solar panels, a bracket is needed to unfold them and place them at a certain angle to face the sun so that they can fully receive sunlight. In order to facilitate outdoor travel and carry them easily, the bracket needs to have a simple structure and be quick and convenient during unfolding and storage.

[0003] At present, a Chinese invention with a publication number of CN217590731U discloses a solar panel bracket and a solar panel, including a fixed cover, a connecting assembly and a supporting seat, wherein the fixed cover is connected to a base plate, one end of the connecting assembly is rotatably connected to the fixed cover, the supporting seat is arranged on the other end of the connecting assembly, and the supporting seat includes an anti-slip part and a magnetic part arranged in the anti-slip part, and the magnetic part can be attracted to the magnetic attraction part on the base plate.

[0004] The existing utility model can effectively improve the static friction between the support base and the ground by arranging anti-slip parts, and a magnetic part is arranged in the anti-slip part of the support base, which can be attracted to the magnetic attraction part on the substrate through the magnetic part, thereby ensuring the connection stability between the solar panel bracket and the substrate when the entire solar panel is in a folded state. However, on the one hand, the area of ​​the solar panel in the prior art is limited by the size of the substrate area. If it is necessary to obtain sufficient power generation efficiency outdoors, the area of ​​the substrate needs to be increased, but this will further reduce the portability; on the other hand, the prior art supports the solar panel through the support base, but in order to increase the power generation efficiency of the solar panel, the surface of the solar panel needs to face the sun. Therefore, the prior art needs to move the substrate to adjust the direction of the substrate when in use, which is inconvenient to use and needs to be improved. Summary of the invention

The first bracket 1, the second bracket 31 and the third bracket 5 are all fixed with solar panels. By setting solar panels on the first bracket 1, the second bracket 31 and the third bracket 5, it is ensured that there is a sufficiently large solar panel area to achieve sufficient power generation efficiency outdoors, and the first bracket 1, the second bracket 31 and the third bracket 5 are folded and attached to each other through the gear hinge mechanism 2 that can rotate within the range of 0-360°, which reduces the space occupied and improves the portability of the photovoltaic solar bracket. The first support assembly 6 and the second support assembly 7 for increasing stability are respectively provided on the second bracket 31 and the third bracket 5. In this embodiment, the first bracket 1, the second bracket 31 and the third bracket 5 are all made of hard plastic material, so as to further reduce the overall weight while ensuring the structural strength, thereby improving the overall portability.

[0025] refer to Figure 1 and Figure 4 Specifically, the gear hinge mechanism 2 includes a mounting groove 21 provided on the first bracket 1 and the second bracket 31, a first gear 22 and a second gear 23 whose axis lines are arranged along a rotation center line parallel to the second bracket 31 are fixedly provided on the first bracket 1 and the second bracket 31, a first rotating shaft 24 and a second rotating shaft 25 are fixedly connected coaxially to the first gear 22 and the second gear 23, the first rotating shaft 24 and the second rotating shaft 25 are connected based on a rotating connecting plate 26, a first rotating hole 27 and a second rotating hole 28 which are coaxially arranged with the first rotating shaft 24 and the second rotating shaft 25 are provided at both ends of the rotating connecting plate 26, the first rotating shaft 24 and the second rotating shaft 25 are rotatably connected in the first rotating hole 27 and the second rotating hole 28, respectively, when the first bracket 1 rotates with the second bracket 31, the first gear 22 is meshed with the second gear 23, and it is not technically difficult for those skilled in the art to apply the gear hinge mechanism 2 to transmission between adjacent second brackets 31 and between the first bracket 1 and the third, so it will not be described in detail in this application. The first gear 22 and the second gear 23 have the same shape, the same diameter and the same number of teeth.

[0026] refer to Figure 1 and Figure 2The stabilizing pawl 43 is slidably connected in the sliding groove 42 to cooperate with the stabilizing ratchet 41 to limit the second bracket 31 from rotating downward on the first bracket 1. The ratchet teeth of the stabilizing ratchet 41 are arranged upward to prevent the second bracket 31 from rotating downward and falling. A return spring 44 is fixedly connected between the stabilizing pawl 43 and the sliding groove 42. A lever 45 is fixedly connected to the stabilizing pawl 43 to drive the stabilizing pawl 43 to disengage from the stabilizing ratchet 41, thereby realizing position adjustment or storage of the second bracket 31. When it is necessary to adjust the angle between the adjacent first bracket 1 and the second bracket 31, and between the adjacent second brackets 31, the stabilizing pawl 43 is disengaged from the stabilizing ratchet 41 by toggling the lever 45, so that the second bracket 31 can rotate freely.

The supporting effect of the third bracket 5 is improved by pulling the first support rod 63 out of the sliding mounting groove 61 and adjusting the angle of the first support rod 63 relative to the sliding seat.

[0028] refer to Figure 1 Specifically, the second support assembly 7 includes a receiving groove 71 symmetrically opened at both ends of the second bracket 31 and a sliding rotation hole 72 opened at the end of the receiving groove 71 away from the first bracket 1. A mounting shaft 73 is movably connected in the sliding rotation hole 72, and a telescopic support rod 74 is fixedly connected to the mounting shaft 73. The telescopic support rod 74 can be stored and placed in the receiving groove 71. When the expansion bracket assembly 3 is unfolded, the telescopic support rod 74 is pulled out of the receiving groove 71 and rotated so that the telescopic support rod 74 is supported on the ground, thereby improving the stability of the expansion bracket assembly 3.

Then, unfold the first support assembly 6 and the second support assembly 7 to improve the structural stability. When storage is required, the first bracket 1, the second bracket 31 and the third bracket 5 are folded together and attached to each other through the gear hinge mechanism 2 that can rotate within the range of 0-360° to achieve storage.
