[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example 1.

[0023] like Figure 1-5 As shown, the photovoltaic panel frame structure described in this embodiment is used to support and fix the photovoltaic panel, including a frame body, the frame body including multiple frame frames 10 and a connector 20, the frame 10 has a mounting groove 11 arranged along its own length direction, and the end face of the frame 10 in the length direction is provided with a through groove 12, the connector 20 has two splicing parts 21 arranged at an angle in the extension direction; multiple frame frames 10 are connected end to end to form the frame body, and any two adjacent frame frames 10 are connected by inserting the splicing part 21 into the through groove 12; a protruding structure 121 is provided on the inner wall surface of the through groove 12, and a stop part 22 that passes over the protruding structure 121 is provided on the outer wall surface corresponding to the splicing part 21 and the protruding structure 121.

[0024] During specific implementation, multiple frames 10 are arranged according to design requirements to form a frame body, and each frame 10 is provided with a mounting groove 11 in the length direction to fix the edge of the photovoltaic panel. Adjacent frames 10 are connected by means of the splicing part 21 of the connecting piece 20, wherein a protruding structure 121 is provided on the inner wall surface of the through groove 12, and a stop part 22 is provided on the outer wall surface of the splicing part 21. When the splicing part 21 is inserted into the through groove 12 and cooperates with the protruding structure 121, the stop part 22 passes over the protruding structure 121 to achieve locking and prevent the splicing part 21 from falling out, thereby ensuring its stability and accurate position, and realizing tool-free rapid assembly.

[0025] In some embodiments, Figure 3 and Figure 5 As shown, the end faces of any two adjacent frames 10 are closely fitted bevel structures to cover the connector 20 located between the two bevel structures. With this structural design, the bevel structure can make the end faces of the frame 10 closely fit, thereby visually forming a continuous, seamless surface, and at the same time, the adjacent through grooves 12 are connected to each other, providing a hidden space for the connector 20, thereby avoiding direct exposure of the connector 20, protecting the connector 20 from direct influence of external environmental factors such as direct sunlight and rain erosion, and helping to extend the service life of the connector 20. In this embodiment, the above-mentioned bevel structure is relatively close to the bottom long side of the frame 10 ( Figure 1 ) is preferably at an inclination angle of 45 degrees.

[0026] In some embodiments, Figure 2 , Figure 3 and Figure 4As shown, the protruding structure 121 is a punching structure formed by punching inwardly on the outer wall surface of the frame 10, and the stopper 22 is a tooth-shaped structure integrally formed with the plug-in portion 21. In this way, by adopting the punching process, the punching structure 121 can be formed in one go. This design not only simplifies the manufacturing process and reduces the production cost, but also improves the overall strength of the protruding structure 121 due to the continuity of the material. In addition, after the plug-in portion 21 is inserted into the through groove 12, the tooth-shaped structure design of the plug-in portion 21 can provide more contact points when the plug-in portion 21 is forced to come out, so as to more effectively resist the pull-out force and ensure that the connector 20 can remain firm under various environmental conditions.

[0027] In some embodiments, Figure 4 As shown, the two splicing parts 21 are arranged vertically. The splicing parts 21 arranged vertically can provide support in two orthogonal directions, can disperse the force more evenly, reduce local stress concentration, and thus improve the overall bearing capacity of the rectangular frame structure.

[0028] In some embodiments, Figure 4 As shown, a guide portion 23 is provided on the opposite side of the two plug-in parts 21, and the guide portion 23 is used to guide the plug-in parts 21 to be inserted into the through groove 12. The existence of the guide portion 23 makes the insertion process of the plug-in parts 21 smoother and more intuitive, thereby improving the convenience of assembly.

[0029] In some embodiments, Figure 4 As shown, the interior of the splicing part 21 is hollow, and a plurality of reinforcing ribs 24 are integrally formed in the splicing part 21. In this embodiment, the hollow design reduces the use of materials, thereby reducing the weight of the splicing part 21, which helps to reduce the weight of the entire frame structure. At the same time, the reinforcing ribs 24 can effectively improve the bending and torsion resistance of the splicing part 21, and can maintain the strength of the structure even in the case of being hollow.

[0030] In some embodiments, Figure 2 As shown, convex ribs 122 are provided on two opposite inner wall surfaces of the through groove 12, the convex rib 122 and the protruding structure 121 are not on the same side, and a plurality of convex ribs 122 are arranged at intervals on the side where the convex ribs 122 are located. When the splicing part 21 is inserted into the through groove 12, the splicing part 21 has a partial interference fit with the frame 10 through the convex ribs 122.

[0031] Utilizing this structural design, the local interference fit achieved by the rib 122 helps to form a tight fit between the insertion portion 21 and the through groove 12, which can reduce component deformation due to assembly stress and also concentrate the assembly stress on a specific contact area (the opposite side where the non-raised structure 121 is located), thereby improving the pull-out resistance.

[0032] In some embodiments, Figure 2 As shown, the groove wall of the installation groove 11 is provided with a straight section 111 and an inclined section 112 along its depth direction, the straight section 111 is provided with a glue groove 13, and the width of the inclined section 112 (in the direction of the frame width) gradually increases along the depth direction of the installation groove 11.

[0033] In the specific implementation, first fill the glue groove 13 with a proper amount of adhesive. This step effectively improves the adhesion between the photovoltaic panel and the mounting groove 11. The design of the straight section 111 provides a stable support for the photovoltaic panel to ensure its horizontal placement. As the depth of the mounting groove 11 increases, the width of the oblique section 112 gradually increases. This design not only provides the necessary space for the adhesive when the photovoltaic panel is inserted to prevent the adhesive from being squeezed and overflowing, but also provides additional accommodation volume for the adhesive after curing. Specifically, when the photovoltaic panel is inserted into the mounting groove 11, the adhesive squeezed by the photovoltaic panel will penetrate into the bottom of the mounting groove 11, and the oblique section 112 with a gradually increasing width provides sufficient space for the adhesive. In this way, after the adhesive is cured, the photovoltaic panel can be more firmly fixed in the mounting groove 11, while the adhesive overflow is avoided to keep the appearance clean.

[0034] In some embodiments, the long sides (sides in the same direction as the length direction of the frame) of the frame 10 are all rounded. Rounded corners can avoid personal injuries caused by sharp edges, and also avoid scratches and damage during transportation and installation.

[0035] The photovoltaic panel frame structure provided in this embodiment has a plug-in design that allows for quick assembly without the need for additional tools, greatly improving installation efficiency and shortening construction periods. The raised structure and stopper design ensure high stability after the frame is connected, eliminating the need for traditional fasteners, effectively reducing material and labor costs, and improving the overall economic benefits of the photovoltaic system. In addition, the compact design of the frame structure and the hidden connection method provide a neat appearance and enhance the overall aesthetics of the photovoltaic system. At the same time, through simplified connection methods and enhanced structural stability, the risk of damage to the connectors due to unexpected environmental factors during subsequent use is reduced, ensuring that the frame has excellent environmental adaptability and sustainability.
