This technical solution has several inherent defects in actual application. First, bolt connection can cause mechanical protrusions at the junction between the photovoltaic panel and the installation frame, damaging the overall integrity and aesthetics of the photovoltaic system. Second, uneven stress distribution of multi-point bolt connection can easily cause local structural deformation, especially under long-term wind load and temperature alternating conditions, the mechanical strength of the connection part decays significantly, which poses a safety hazard of insufficient structural stability. Third, this installation method requires multiple steps of hole alignment and tightening operation, which not only complicates the installation process, consumes time and effort, but also requires repeated disassembly during maintenance, significantly increasing the installation and maintenance cost of the system. SUMMARY

[0007] Vertical frames are arranged on the left and right sides of the photovoltaic panel, and the cross section of the vertical frame is concave. The photovoltaic panel is embedded between the vertical frames on the left and right sides.

[0008] Horizontal frames are arranged on the upper and lower sides of the photovoltaic panel, and the cross section of the horizontal frame is concave. The photovoltaic panel is embedded between the horizontal frames on the upper and lower sides.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The specific structure of an embedded rigid photovoltaic module includes a photovoltaic panel 1. The photovoltaic panel 1 is a photovoltaic power generation device that directly converts solar radiation energy into electrical energy through the photoelectric effect or photochemical effect. Its core components are typically made of crystalline silicon. For example... Figure 2 As shown, the photovoltaic panel 1 in the prior art has an inwardly bent back rib 101 on its back side. The photovoltaic panel 1 is fixed by the back rib 101.

[0035] like Figure 1 and 3 As shown, the specific structure of the embedded rigid photovoltaic module also includes vertical frames 3 and horizontal frames 2. Vertical frames 3 are located on the left and right sides of the photovoltaic panel 1. The cross-section of the vertical frames 3 is concave. The photovoltaic panel 1 is embedded between the left and right vertical frames 3, with its left and right edges inserted into the grooves of the vertical frames 3. Horizontal frames 2 are located on the top and bottom sides of the photovoltaic panel 1. Horizontal frames 2 have a concave cross-section. The photovoltaic panel 1 is embedded between the top and bottom horizontal frames 2, with its top and bottom edges inserted into the grooves of the horizontal frames 2.

[0036] An embedded installation structure is adopted, in which the photovoltaic panel 1 is embedded around the perimeter into a frame composed of vertical frames 3 and horizontal frames 2, forming a distributed pressure-bearing system with full circumferential linear contact. This structure increases the fixed contact area by more than 200% compared to the traditional bolt connection method, effectively achieving uniform load transfer, eliminating local stress concentration, and reducing the risk of structural deformation by more than 70% after testing, while also improving the wind pressure resistance of the module.

[0037] A reinforcing member 4 is provided at the connection between the vertical frame 3 and the horizontal frame 2, and the reinforcing member 4 is snapped into the adjacent vertical frame 3 and horizontal frame 2. The reinforcing member 4 is a sheet metal structure.

[0038] like Figure 4As shown, the reinforcing member 4 includes a plate 401. A slot 404 is concave at both ends of the plate 401, and the slots 404 at both ends of the plate 401 are perpendicular to each other. The slots 404 are fastened to the outer periphery of the vertical frame 3 or the horizontal frame 2. This allows the vertical frame 3 and the horizontal frame 2 to form a square frame, thereby securing the photovoltaic panel 1.

[0039] The plate 401 has a raised flange 403, which engages with the back reinforcement 101 to further fix the position of the photovoltaic panel 1. The plate 401 has a connecting beam 402 with one end suspended, and the flange 403 is located at the suspended end of the connecting beam 402. In practice, the connecting beam 402 is formed by laser cutting, while the flange 403 is formed by stamping. The connecting beam 402 has an operating hole 405. A stress relief hole 406 is provided at the connection between the connecting beam 402 and the plate 401.

[0040] When assembling or disassembling the reinforcing member 4, a screwdriver can be inserted into the operating hole 405, and force can be applied to the connecting beam 402 by rotating the screwdriver to cause it to undergo elastic deformation. At this time, the folded edge 403 connected to the connecting beam 402 no longer protrudes from the plate body 401, thereby releasing the assembly constraint on the photovoltaic panel 1 and facilitating the installation and disassembly of the reinforcing member 4 and the photovoltaic panel 1.

[0041] The panel 401 has a threaded hole 407, and a bolt 5 is threaded into the threaded hole 407. The bolt 5 abuts against the back side of the photovoltaic panel 1. By tightening the bolt 5, the photovoltaic panel 1 can be further fixed.

[0042] The inner side of the slot 404 is provided with a protruding retaining strip 408, which engages with the vertical frame 3 and the horizontal frame 2. The retaining strip 408 makes the fixation between the slot 404 and the vertical frame 3 and the horizontal frame 2 more secure.

[0043] By incorporating reinforcing member 4 and mechanically coupling it with photovoltaic panel 1, vertical frame 3, and horizontal frame 2 via snap-fit ​​connections, a multi-point stress dispersion mechanism is formed, which can increase the shear strength of the connection nodes by 45%. Furthermore, reinforcing member 4 employs a snap-fit ​​quick assembly method, enabling rapid assembly of reinforcing member 4 with photovoltaic panel 1, vertical frame 3, and horizontal frame 2. This shortens installation time and improves efficiency by more than 5 times compared to traditional fastening methods. It also features reversible disassembly, significantly improving on-site construction efficiency and reducing maintenance costs.

[0044] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
