DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1-5 As shown, a frame structure for a solar photovoltaic module includes a frame body 1 and corner codes 6 that are plug-connected. Four frame bodies 1 and four corner codes 6 are combined into a rectangular frame structure for installing and fixing the photovoltaic module. The four frame bodies 1 can be combined with two relatively long lengths and two relatively short lengths, which is specifically determined according to the size of the photovoltaic module. The frame body 1 includes a first vertical side 11, a first horizontal side 12, a second vertical side 13, a third vertical side 14, a second horizontal side 15, a fourth vertical side 16, a third horizontal side 17 and a fifth vertical side 18 which are connected in sequence. The upper ends of the first vertical side 11 and the fifth vertical side 18 are pressed together to form a pressing and fastening portion 3 to achieve the final fastening of the frame body 1; the third vertical side 14, the second horizontal side 15, and the fourth vertical side 16 form a mounting groove 4 for the clamping and installation of photovoltaic components; the first vertical side 11, the first horizontal side 12, the fourth vertical side 16 and the third horizontal side 17 form a connecting cavity 5 for the insertion of the corner code 6 to achieve the connection of two adjacent frame bodies 1, and the erected fourth vertical side 16 can cooperate with the second horizontal side 15 and the third vertical side 14 to form the mounting groove 4.

[0021] In the present application, the connecting ends of the second vertical side 13 and the third vertical side 14 are bent toward the direction of the installation groove 4 to form an inwardly bent portion 2. The inwardly bent portion 2 can press the edge of the photovoltaic module, provide limited support for the photovoltaic module, and increase the installation firmness of the photovoltaic module. The inwardly bent portion 2, the third vertical side 14, the second horizontal side 15, and the installed photovoltaic module form a glue storage tank, and the glue storage tank stores glue to enhance the installation firmness of the photovoltaic module. The bent ends of the second vertical side 13 and the third vertical side 14 in the inwardly bent portion 2 are not fitted to form a reinforcement hole 21. The reinforcement hole 21 is in the shape of a water drop, which is convenient for the bending of the connecting ends of the second vertical side 13 and the third vertical side 14. The non-fitting structural design can increase the curvature of the inwardly bent portion 2, thereby increasing the volume of the glue storage tank and increasing the amount of glue storage, so that the combination of the second vertical side 13 and the third vertical side 14 is more secure and does not lose strength. At least one fourth groove 141 is provided on the side of the third vertical side 14 close to the mounting groove 4, which can increase the contact area between the glue and the third vertical side 14 and improve the adhesive strength of the glue; it can increase the volume of the glue storage tank and play a more effective anti-overflow effect. A plurality of third grooves 131 are provided on the side of the second vertical side 13 away from the third vertical side 14. The third grooves 131 are anti-skid grooves, which can effectively reduce the sliding of the arranged and stacked frame bodies 1, play an anti-skid effect, and prevent the frame bodies 1 from sliding during the shipping process. A plurality of fifth grooves 152 are provided on the side of the second horizontal side 15 close to the mounting groove 4. The plurality of fifth grooves 152 are evenly arranged along the length direction of the second horizontal side 15. The structural design purpose of the fifth grooves 152 is to provide elastic accommodation space for the thermal expansion and contraction of the photovoltaic module in the natural environment, ensure the structural safety of the photovoltaic module and enhance the installation firmness of the photovoltaic module.

[0022] In one solution of the present application, a plurality of ridges 151 are provided on the side of the second horizontal edge 15 close to the mounting groove 4, and the plurality of ridges 151 are arranged along the length direction of the second horizontal edge 15. Through the structural arrangement of the ridges 151, stress elimination during the molding of the frame body can be improved, the molding effect of the frame body can be improved, and the structural strength of the second horizontal edge 15 can be improved.

[0023] In the second scheme of the present application, a sixth groove 171 is provided on the side of the third horizontal side 17 away from the connecting cavity 5, and the sixth groove 171 is arranged along the length direction of the third horizontal side 17. The sixth groove 171 is a reinforcing rib groove, which is an inwardly concave arc structure, which can strengthen the structural strength of the third horizontal side 17 and can strengthen the clamping firmness of the limiting protrusion 172 thereon to the diagonal code 6, thereby preventing the third horizontal side 17 from being subjected to long-term force and bulging outward, thereby loosening the connection with the diagonal code 6, and finally causing the frame structure to be loose, thereby affecting the installation firmness of the photovoltaic module.

[0024] Among them, the limiting protrusion 172 is a half-cut protrusion structure, and its inclined surface direction is inclined toward the center direction of the connecting cavity 5. The limiting protrusion 172 with the half-cut protrusion structure can enhance the clamping effect with the angle code 6 to prevent the angle code from slipping out of the connecting cavity 5.

[0025] In another embodiment of the present application, at least one leaking hole 111 and two positioning holes 113 are provided on the first vertical side 11, and at least one first groove 112 is provided on the side of the first vertical side 11 away from the connecting cavity 5, and the first groove 112 is arranged along the length direction of the first vertical side 11. The structural design of the first groove 112 can effectively prevent the diagonal bracket 6 from slipping and strengthen the structural strength of the first vertical side 11. The setting of the leaking hole 111 can drain the rainwater that penetrates into the connecting cavity 5, and prevent the frame body 1 from being corroded due to long-term water storage in the connecting cavity 5, thereby reducing the life of the frame structure. The setting of the positioning holes 113 facilitates the processing and positioning of the frame body 1 and the positioning of the frame structure during assembly, and at least two positioning holes 113 can ensure the positioning accuracy of the frame body 1.

[0026] In another embodiment of the present application, at least one second groove 121 is provided on the side of the first horizontal side 12 away from the connecting cavity 5. The second groove 121 is arranged along the length direction of the first horizontal side 12, which can strengthen the structural strength of the second horizontal side 12 and improve the insertion firmness of the angle code.

[0027] In other schemes of the present application, the clamping and fastening part 3 is formed by double-layer lamination and riveting of the first vertical side 11 and the fifth vertical side 18, so as to strengthen the connection firmness of the first vertical side 11 and the fifth vertical side 18. By continuously bending the first vertical side 11 twice, bending the fifth vertical side 18 once, and then buckling and riveting the first vertical side 11 and the fifth vertical side 18 to form a double-layer lamination, the connection firmness of the first vertical side 11 and the fifth vertical side 18 can be effectively improved; at the same time, it is not limited to double-layer lamination and riveting, and can also be a single-layer lamination and riveting or a multi-layer lamination and riveting structure. The clamping and fastening part 3 is provided with a plurality of pressing and fixing areas 31 along its length direction, which can further strengthen the connection firmness of the first vertical side 11 and the fifth vertical side 18. At the same time, other methods such as welding and screwing can also be used to improve the connection firmness of the first vertical side 11 and the fifth vertical side 18.

[0028] In the present application, the frame body 1 is formed by bending and shearing in one piece, and cold bending is adopted, which can realize rapid bending and forming of the frame body 1, and has high forming efficiency. The frame body 1 is made of metal material, such as steel, aluminum alloy or other metal alloy, which has high structural strength and is not easy to rust or corrode, and the cost is relatively low.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents.
