[0034] This embodiment relates to a multi-angle adjustable bracket, see reference. Figure 1 The system includes: a support member 200, a connector 300, and a fastener 400. One end of the support member 200 is mounted on the back of the photovoltaic panel 100; one end of the connector 300 is connected to the back of the photovoltaic panel 100; the fastener 400 is located at the other end of the connector 300; one or more fasteners 400 are provided, and the support member 200 has multiple adjustment holes 211; or, multiple fasteners 400 are provided, and the support member 200 has one adjustment hole 211; the fastener 400 cooperates with the adjustment hole 211 to adjust the tilt angle of the photovoltaic panel 100. Specifically, one end of the support member 200 supports the photovoltaic panel 100, one end of the connector 300 is connected to the back of the photovoltaic panel 100, and a fastener 400 is disposed at the other end of the connector 300. The tilt angle of the photovoltaic panel 100 can be adjusted by using one fastener 400 with different adjustment holes 211 on the support member 200, different fasteners 400 with one adjustment hole 211 on the support member 200, or different fasteners 400 with different adjustment holes 211 on the support member 200, so that the surface of the photovoltaic panel 100 is kept on the optimal sun-facing side, maximizing the utilization of solar energy resources and improving the output power and power generation of the photovoltaic panel 100. This multi-angle adjustable bracket has a simple overall structure, is easy to assemble and disassemble to facilitate the movement of the photovoltaic panel 100, and the adjustment method of the fastener 400 cooperating with the adjustment hole 211 is simple. In this embodiment, one end of the support member 200 is assembled on the upper side of the back of the photovoltaic panel 100, and one end of the connector 300 is connected to the lower side of the back of the photovoltaic panel 100.

[0035] In some embodiments, a single fastener 400 may be provided, and multiple adjustment holes 211 are provided at different positions on the support member 200. The fastener 400 cooperates with the multiple adjustment holes 211 at different positions to change the tilt angle of the photovoltaic panel 100. In other embodiments, multiple fasteners 400 may be provided and provided at different positions on the connector 300. The support member 200 may be provided with one adjustment hole 211. By having different fasteners 400 cooperate with the adjustment hole 211, the tilt angle of the photovoltaic panel 100 can be changed.

[0036] In this embodiment, refer to Figure 1 and Figure 3Multiple fasteners 400 are provided, arranged sequentially towards the direction away from the center of the connector 300; multiple adjustment holes 211 are provided on the support member 200, arranged sequentially towards the direction away from the photovoltaic panel 100. Specifically, the multiple fasteners 400 and multiple adjustment holes 211 provide multiple ways to adjust the tilt angle of the photovoltaic panel 100: First, the operator can engage different fasteners 400 with the same adjustment hole 211, thereby changing the tilt angle of the photovoltaic panel 100 by changing the distance between the end of the connector 300 connected to the back of the photovoltaic panel 100 and the adjustment hole 211; Second, the same fastener 400 can be engaged with adjustment holes 211 at different positions to change the tilt angle of the photovoltaic panel 100. Specifically, tilt angles such as 40° and 50° are marked at different adjustment holes 211 on the support 200, corresponding to the actual tilt angles of the photovoltaic panel 100, facilitating quick adjustment of the tilt angle of the photovoltaic panel 100. Thirdly, different fasteners 400 are engaged with different adjustment holes 211 to change the tilt angle of the photovoltaic panel 100, allowing for detailed adjustments to the tilt angle of the photovoltaic panel 100 according to actual scenarios and needs. In this embodiment, three fasteners 400 are provided. Four adjustment holes 211 are provided, and the four adjustment holes 211 are arranged on the same straight line. The fasteners 400 are rivets, riveted to the adjustment holes 211. In some embodiments, four fasteners 400 and three adjustment holes 211 may also be provided. The fasteners 400 may also be plastic fasteners.

[0037] In some embodiments, refer to Figure 2 as well as Figure 5 The support member 200 has a through hole 212 at one end near the photovoltaic panel 100. The through hole 212 allows the end of the connector 300 equipped with the fastener 400 to pass through. When the connector 300 is too long, the through hole 212 serves as a fixed insertion point. The end of the connector 300 equipped with the fastener 400 passes through the through hole 212 and then folds back to engage with the adjustment hole 211, enabling fine-tuning of the length of the connector 300 and preventing the inability to effectively adjust the tilt angle of the photovoltaic panel 100 due to the connector 300 being too long. When the end of the connector 300 equipped with the fastener 400 passes through the through hole 212, the fastener 400 engages with the adjustment hole 211, at which point the fastener 400 is engaged on the side of the support member 200 facing away from the photovoltaic panel 100.

[0038] Furthermore, referring to Figure 3The connector 300 includes a first connecting strap 310 and a second connecting strap 320. One end of the first connecting strap 310 is connected to the back of the photovoltaic panel 100, and the other end is provided with a buckle 400. One end of the second connecting strap 320 is connected to the first connecting strap 310, and the other end is connected between the back of the photovoltaic panel 100 and one end of the support member 200. One end of the first connecting strap 310 is connected to the lower side of the back of the photovoltaic panel 100. The first connecting strap 310 and the second connecting strap 320 are arranged in a herringbone pattern to increase the stability of the connection between the first connecting strap 310, the second connecting strap 320 and the photovoltaic panel 100. In this embodiment, both the first connecting strap 310 and the second connecting strap 320 are woven straps to reduce the overall weight of the multi-angle adjustable bracket, facilitating operation and movement of the photovoltaic panel 100.

[0039] In some embodiments, refer to Figures 4-5 The support member 200 includes a support member body 200 and a bendable portion 220 disposed at one end of the support member body 200; the bendable portion 220 is assembled to the back of the photovoltaic panel 100. The support member body 200 and the bendable portion 220 cooperate to ensure that the photovoltaic panel 100 can be provided with sufficient support force while ensuring that the photovoltaic panel 100 can be adjusted to various tilt angles as needed. Furthermore, an adhesive layer 221 is provided on the side of the bendable portion 220 facing the photovoltaic panel 100. The adhesive layer 221 is used to bond the bendable portion 220 to the photovoltaic panel 100, ensuring the stability of the assembly of the bendable portion 220 and the back of the photovoltaic panel 100. The adhesive layer 221 is formed by coating with silicone and hot melt adhesive.

[0040] In some embodiments, refer to Figure 6 The support member 200 includes: a fiberglass board 230, a first buffer layer 240, a second buffer layer 250, a first flexible layer 260, and a second flexible layer 270.

The first buffer layer 240 is disposed on the first surface 231; the second buffer layer 250 is disposed on the second surface 232; the first flexible layer 260 is disposed on the side of the first buffer layer 240 facing away from the fiberglass board 230; and the second flexible layer 270 is disposed on the side of the second buffer layer 250 facing away from the fiberglass board 230. The fiberglass board 230 has sound absorption, sound insulation, heat insulation, environmental friendliness, and flame retardancy properties. Both the first buffer layer 240 and the second buffer layer 250 are made of EVA material. The first flexible layer 260 and the second flexible layer 270 are made of fabric. The fiberglass board 230, the first buffer layer 240, the second buffer layer 250, the first flexible layer 260, and the second flexible layer 270 are pressed together at a high temperature of 145°C.

[0041] Furthermore, the thickness of the fiberglass board 230 is less than or equal to 3 mm. In some embodiments, the thickness of the fiberglass board 230 is set to 3 mm. In other embodiments, the thickness of the fiberglass board 230 can also be set to 2.5 mm, 2.0 mm, 1.5 mm, 1.0 mm, etc. It is sufficient that the thickness of the fiberglass board 230 is less than or equal to 3 mm; no specific limitation is imposed here.
