Rubber pads are then bonded to the inner wall of the cross, and the rubber pads are then bonded to the photovoltaic main body to form a flexible buffer structure. When the photovoltaic panel is installed at an angle and encounters strong winds, the rubber pads can effectively absorb and disperse the impact energy of the wind on the middle of the photovoltaic panel, reduce the stress concentration between the glass and the electromagnetic sheet, avoid the problem of electromagnetic sheet breakage caused by fluctuations in the middle gap, significantly enhance the structural stability and wind resistance of the photovoltaic module in harsh wind environments, and extend the service life of the module.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This application provides a technical solution: an aluminum alloy profile for a photovoltaic panel frame, including a frame body 1, four mounting angle steels 2 are fixedly installed in a rectangular array on the inner wall of the frame body 1, the same cross 3 is fixedly installed on the inner wall of each mounting angle steel 2, a rubber pad 4 is bonded to the inner wall of the cross 3, and a photovoltaic body 5 is bonded to the inner wall of the rubber pad 4.

[0029] In the technical solution of this application, four mounting angle steels 2 are set in a rectangular array on the inner wall of the main body and fixed with the same cross 3. Rubber pads 4 are glued to the inner wall of the cross 3, and the rubber pads 4 are then glued to the photovoltaic main body 5 to form a flexible buffer structure. When the photovoltaic panel is installed at an angle and encounters strong winds, the rubber pads 4 can effectively absorb and disperse the impact energy of the wind on the middle of the photovoltaic panel, reduce the stress concentration between the glass and the electromagnetic sheet, avoid the problem of electromagnetic sheet breakage caused by the fluctuation of the middle gap, significantly enhance the structural stability and wind resistance of the photovoltaic module in harsh wind environments, and extend the service life of the module.

[0030] In the technical solution of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the photovoltaic main body 5 includes two vertical rods 101 and two horizontal rods 102. The two vertical rods 101 and two horizontal rods 102 are arranged in a U-shape. The U-shaped arrangement of the horizontal rods 102 and vertical rods 101 facilitates the installation of the photovoltaic panels. Positioning holes 103 are respectively opened in the inner walls of the two vertical rods 101 and two horizontal rods 102. L-shaped angle steel 104 is slidably connected to the inner wall of the end of the horizontal rod 102 and the vertical rod 101 located inside each positioning hole 103. The positioning holes 103 can provide sliding positioning for the L-shaped angle steel 104. One L-shaped angle steel 104 can be used to position the ends of one horizontal bar 102 and one vertical bar 101. Four L-shaped angle steels 104 can be used to position the corners of two horizontal bars 102 and two vertical bars 101. The vertical bars 101, horizontal bars 102 and cross bars 3 are made of aluminum, which can enhance their service life. The L-shaped angle steel 104 and the mounting angle steel 2 are made of stainless steel, which can ensure their service life.

[0031] In the technical solution of this application, such as Figures 1-4 As shown, mounting grooves 105 are respectively provided in the inner walls of the two vertical rods 101 and the two horizontal rods 102. The inner walls of the vertical rods 101 and the horizontal rods 102 located inside the corresponding mounting grooves 105 are slidably engaged with the photovoltaic body 5. The mounting grooves 105 facilitate the engagement and installation of the horizontal rods 102 and the vertical rods 101 with the photovoltaic body 5.

[0032] In use, four mounting angle steels 2 are fixed to the inner wall of the frame body 1 in a rectangular array. The same cross 3 is securely installed by the mounting angle steels 2. After the rubber pad 4 is glued to the inner wall of the cross 3, the photovoltaic body 5 is glued to the inner wall of the rubber pad 4 to form a flexible buffer system. When the tilted photovoltaic panel encounters strong wind, the vibration energy generated by the wind impacting the middle of the photovoltaic panel is absorbed and dispersed step by step by the elastic deformation of the rubber pad 4, which reduces the stress peak between the glass and the electromagnetic sheet and makes the distribution more uniform. This avoids the violent fluctuation of the middle gap caused by the traditional rigid frame under strong wind, thereby eliminating the risk of the electromagnetic sheet breaking due to stress concentration. Ultimately, it achieves stable operation and extended life of the photovoltaic module in complex wind environments. In addition, the corners of the transmission frame are generally positioned by positioning bolts, while the mounting angle steel 2 can also position the frame body 1 when positioning the cross 3.
