[0025] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0026] The following is for reference. Figures 1-3 The frame 100 of the photovoltaic module according to an embodiment of the present utility model is described.

[0027] like Figures 1-3As shown, the frame 100 of the photovoltaic module according to the first aspect embodiment of the present invention includes: an outer frame 10 and an inner frame 20. The outer frame 10 includes an outer frame body 11 and a first engagement structure 12. The first engagement structure 12 is connected to one end of the outer frame body 11 and is bent relative to the outer frame body 11. The first engagement structure 12 forms an engagement groove 13. The inner frame 20 is disposed inside the outer frame 10 and is integrally formed with the outer frame 10. The inner frame 20 includes an inner frame body 21, a first support portion 22 and a first engagement portion 23. One end of the inner frame body 21 is connected to the other end of the outer frame body 11 and is bent relative to the outer frame body 11. The inner frame body 21 is configured with an installation groove 24 for mounting photovoltaic cells. One end of the first support part 22 is connected to the other end of the inner frame body 21 and is bent relative to the inner frame body 21. The first interlocking part 23 is connected to the other end of the first support part 22 and is bent relative to the first support part 22. The first interlocking part 23 is disposed in the interlocking groove 13. The first support part 22 is attached to the outer frame body 11, and the first interlocking structure 12 is attached to the first support part 22. The first interlocking structure 12, the first interlocking part 23, the first support part 22 and the outer frame body 11 form at least six layers of stacked structure.

[0028] It is understood that the outer frame body 11 and the first interlocking structure 12 constitute the main structure of the outer frame 10, and the inner frame body 21, the first support part 22 and the first interlocking part 23 constitute the main structure of the inner frame 20. The first interlocking structure 12 is located at one end of the outer frame body 11, which can improve the extensibility of the outer frame 10. Moreover, the first interlocking structure 12 is bent relative to the outer frame body 11, so that the first interlocking structure 12 can be close to the other end of the outer frame body 11, thereby increasing the thickness of one end of the outer frame 10. The first interlocking structure 12 forms an interlocking groove 13, which can create a placement space in the first interlocking structure 12, thereby facilitating the placement of the components of the inner frame 20 in the interlocking groove 13. The inner frame 20 is located inside the outer frame 10, so that the inner frame 20 and the outer frame 10 can form a frame structure. Moreover, the inner frame 20 and the outer frame 10 are integrally formed, thereby improving the structural strength of the photovoltaic module frame 100.

[0029] The inner frame body 21 is connected to the outer frame body 11 at the end away from the first interlocking structure 12, and the inner frame body 21 is bent relative to the outer frame body 11, thereby forming a frame structure between the inner frame 20 and the outer frame 10, which can improve the structural strength of the photovoltaic module frame 100. The inner frame body 21 forms a mounting groove 24, which can limit the photovoltaic cells, thereby facilitating the installation of the photovoltaic cells on the photovoltaic module frame 100. One end of the first support part 22 is connected to the end of the inner frame body 21 away from the outer frame body 11, and the first support part 22 is bent relative to the inner frame body 21. The bending allows the first support portion 22 to approach one end of the inner frame body 21, thereby increasing the thickness of the frame 100. The first engagement portion 23 is connected to one end of the first support portion 22, and the first engagement portion 23 is bent relative to the first support portion 22, thereby facilitating the first engagement portion 23 to approach the inner frame body 21. A portion of the first engagement portion 23 extends into the engagement groove 13, thereby allowing the first engagement structure 12 to press the first engagement portion 23 tightly, thereby enabling the inner frame body 21 and the outer frame body 11 to form a multi-layer structure, and also facilitating the rapid forming of the frame 100 of the photovoltaic module.

[0030] In addition, the first support part 22 is attached to the outer frame body 11, and the first interlocking structure 12 is attached to the first support part 22. This arrangement can save the space occupied by the first support part 22 and the first interlocking structure 12. The first interlocking structure 12, the first interlocking part 23, the first support part 22 and the outer frame body 11 form at least six layers of stacked structure. The traditional photovoltaic module frame 100 is formed by multiple curlings at the edge of the sheet cold bending, which has the problems of complex process, high processing difficulty and high cost. Moreover, multiple curlings will cause stress concentration at the edge, which is prone to cracks and affect the quality and service life of the frame 100.

[0031] For example, Figures 1-3 During the bending process of the frame 100 of the photovoltaic module, the first interlocking structure 12 and the first support 22 are bent on both sides with the first interlocking part 23, so that one end of the outer frame body 11 and the inner frame body 21 can form at least six layers of stacked structure. This not only further improves the strength of the frame 100, but also prevents the interlocking part from loosening. It also has the advantages of simple processing and reduced cost.

[0032] Therefore, in the frame 100 of the photovoltaic module, the first interlocking structure 12 is bent relative to the outer frame body 11, the inner frame body 21 is bent relative to the outer frame body 11, the first support part 22 is bent relative to the inner frame body 21, and the first interlocking part 23 is bent relative to the first support part 22. The first interlocking part 23 is disposed in the interlocking groove 13. The first interlocking structure 12, the first interlocking part 23, the first support part 22 and the outer frame body 11 form at least six layers of stacked structure, which can not only further improve the strength of the frame 100, but also prevent the interlocking parts from loosening. It also has the advantages of simple processing and reduced cost.

[0033] Among them, such as Figures 1-3 As shown, the first occlusal structure 12 includes a second occlusal portion 121, a third occlusal portion 122, and a fourth occlusal portion 123. One end of the second occlusal portion 121 is connected to the outer frame body 11 and is bent relative to the outer frame body 11. One end of the third occlusal portion 122 is connected to the other end of the second occlusal portion 121 and is bent relative to the second occlusal portion 121. One end of the fourth occlusal portion 123 is connected to the other end of the third occlusal portion 122 and is bent relative to the third occlusal portion 122. The fourth occlusal portion 123 is attached to the third occlusal portion 122 and forms an occlusal groove 13 with the second occlusal portion 121. The first occlusal portion 123, the second occlusal portion 121, the third occlusal portion 122, the fourth occlusal portion 123, the first support portion 22, and the outer frame body 11 form a six-layer stacked structure.

[0034] Understandably, the second occlusal portion 121, the third occlusal portion 122, and the fourth occlusal portion 123 constitute the main body of the first occlusal structure 12. The second occlusal portion 121 is connected to the outer frame body 11 and is bent relative to the outer frame body 11, thereby allowing the second occlusal portion 121 to be close to one end of the outer frame body 11. The third occlusal portion 122 is connected to the end of the second occlusal portion 121 away from the outer frame body 11, and is also bent relative to the second occlusal portion 121, thereby allowing both the second and third occlusal portions 121 and 122 to be bent relative to the outer frame body 11. The fourth occlusal portion 123 is connected to the end of the third occlusal portion 122 away from the second occlusal portion 121, thereby allowing the second occlusal portion 121 and 122 to be bent relative to the outer frame body 11. The fourth engagement part 123 is connected sequentially to facilitate the bending of the second engagement part 121, the third engagement part 122 and the fourth engagement part 123 relative to the outer frame body 11. Moreover, the fourth engagement part 123 is attached to the third engagement part 122, thereby saving the area occupied by the first engagement structure 12. The fourth engagement part 123 and the second engagement part 121 form an engagement groove 13. This arrangement allows the engagement groove 13 to be pressed and engaged with the first engagement part 23. The first engagement part 23, the second engagement part 121, the third engagement part 122, the fourth engagement part 123, the first support part 22 and the outer frame body 11 form a six-layer stacked structure, which can not only further improve the strength of the frame 100, but also prevent loosening at the engagement point, and has the advantages of simple processing and reduced cost.

[0035] In addition, if Figures 1-3 As shown, the first biting part 23 is provided with a first mounting hole, the second biting part 121 is provided with a second mounting hole, the third biting part 122 is provided with a third mounting hole, the fourth biting part 123 is provided with a fourth mounting hole, the first support part 22 is provided with a fifth mounting hole, and the main body of the frame 100 is provided with a sixth mounting hole. The first mounting hole, the second mounting hole, the third mounting hole, the fourth mounting hole, the fifth mounting hole and the sixth mounting hole are arranged opposite to each other.

[0036] In other words, a first mounting hole is provided on the first interlocking part 23, a second mounting hole is provided on the second interlocking part 121, a third mounting hole is provided on the third interlocking part 122, a fourth mounting hole is provided on the fourth interlocking part 123, a fifth mounting hole is provided on the first support part 22, and a sixth mounting hole is provided on the main body of the frame 100. The first, second, third, fourth, fifth, and sixth mounting holes are arranged opposite to each other. This arrangement facilitates mutual positioning between the first interlocking part 23, the second interlocking part 121, the third interlocking part 122, the fourth interlocking part 123, the first support part 22, and the main body of the frame 100. This allows the first interlocking part 23, the second interlocking part 121, the third interlocking part 122, the fourth interlocking part 123, the first support part 22, and the main body of the frame 100 to be connected by fasteners, thereby improving the structural strength of the frame 100 of the photovoltaic module.

[0037] Optionally, such as Figures 1-3 As shown, the width of the first support part 22 is d1, and the width of the first engagement part 23 is d2. d1 and d2 satisfy the relationship: 0.1d1≤d2≤0.3d1.

[0038] It is understandable that the width of the first biting part 23 is greater than or equal to one-tenth of the width of the first support part 22, or the width of the first biting part 23 is less than or equal to three-tenths of the width of the first support part 22. This can increase the contact area between the first support part 22 and the first biting part 23, thereby reducing the force on the first support part 22 and the first biting part 23, and thus avoiding stress concentration between the first support part 22 and the first biting part 23.

[0039] In addition, if Figures 1-3 As shown, the outer frame body 11 includes: a first top plate 111, a first side plate 112 and a first bottom plate 113. The first side plate 112 is bent and connected between the first top plate 111 and the first bottom plate 113. The first bottom plate 113 is in close contact with the first support part 22.

[0040] In other words, the first top plate 111, the first side plate 112, and the first bottom plate 113 constitute the outer frame body 11. The first side plate 112 is located between the first top plate 111 and the first bottom plate 113, and the first top plate 111 and the first bottom plate 113 are arranged in parallel. The first side plate 112 has a certain angle relative to the first top plate 111 and the first bottom plate 113, so that the first top plate 111, the first side plate 112, and the first bottom plate 113 can form a "C" shape. This ensures that the inner side of the outer frame body 11 forms an installation space and improves the structural strength of the outer frame body 11. The first bottom plate 113 and the first support part 22 are in close contact. This arrangement increases the contact area between the first bottom plate 113 and the first support part 22, thereby reducing the stress on the first bottom plate 113 and the first support part 22 and avoiding stress concentration between the first bottom plate 113 and the first support part 22.

[0041] In addition, if Figures 1-3 As shown, the inner frame body 21 includes: a mounting part 211 and a second support part 212. The mounting part 211 is connected to the first top plate 111 and is bent relative to the first top plate 111. The mounting part 211 forms a mounting groove 24 for mounting photovoltaic modules. The second support part 212 is bent and connected between the mounting part 211 and the first support part 22. The second support part 212 abuts against the first bottom plate 113.

[0042] It is understood that the mounting part 211 and the second support part 212 constitute the inner frame body 21. The mounting part 211 is connected to one end of the first top plate 111, and the mounting part 211 is bent to be close to the outer frame body 11, which facilitates the rivet pressing connection between the mounting part 211 and the outer frame body 11. The inner side of the mounting part 211 forms a mounting groove 24, which can limit the photovoltaic module, thereby facilitating the fixing of the photovoltaic module on the frame 100. The second support part 212 is located between the mounting part 211 and the first support part 22, and the second support part 212 is inclined relative to the mounting part 211 and the first support part 22. The second support part 212 abuts against the first bottom plate 113. This arrangement allows the second support part 212 to support the mounting part 211 and the first support part 22, thereby improving the structural strength of the inner frame body 21 and facilitating the connection between the inner frame body 21 and the outer frame body 11.

[0043] Among them, such as Figures 1-3As shown, the mounting part 211 includes: a second top plate 213, a second side plate 214, and a second bottom plate 215. The second top plate 213 is connected to one end of the first top plate 111 and is bent relative to the first top plate 111. One end of the second side plate 214 is connected to the other end of the second top plate 213 and is bent relative to the second top plate 213. The second top plate 213 is attached to the first top plate 111, the second side plate 214 is attached to the first side plate 112, and the second bottom plate 215 is connected to the other end of the second side plate 214 and is bent relative to the second side plate 214. The second top plate 213, the second side plate 214, and the second bottom plate 215 together form a mounting groove 24. The second bottom plate 215 is connected to the second support part 212.

[0044] In other words, the second top plate 213, the second side plate 214, and the second bottom plate 215 constitute the main structure of the mounting part 211. The second top plate 213 is connected to one side of the first top plate 111, and the second top plate 213 is bent relative to the first top plate 111. This arrangement facilitates the fit between the first top plate 111 and the second top plate 213, thereby increasing the contact area between the first top plate 111 and the second top plate 213 and preventing stress concentration between the first top plate 111 and the second top plate 213. The second side plate 214 is located inside the first side plate 112 and is connected between the second top plate 213 and the second bottom plate 215. The second side plate 214 is inclined at a certain angle relative to the second top plate 213 and the second bottom plate 215, so that the mounting part 211 and the outer frame body 11 can be stacked, thereby improving the structural strength of the outer frame body 11 and the inner frame body 21.

[0045] In addition, if Figures 1-3 As shown, the second support portion 212 includes a support plate 216 and a protruding plate 217. The protruding plate 217 is disposed at both ends of the support plate 216 and abuts against the first base plate 113 and the second base plate 215 respectively. The protruding plate 217 protrudes in a direction away from the first side plate 112. The second support portion 212 is spaced apart from the first side plate 112, and a cavity is formed between the first side plate 112, the first base plate 113, the second base plate 215, the support plate 216 and the protruding plate 217. The cavity is used to install corner brackets.

[0046] It is understood that the support plate 216 and the protruding plate 217 constitute the main structure of the second support part 212. The protruding plate 217 is connected to both ends of the support plate 216 and is connected to the first base plate 113 and the second base plate 215 respectively, so that the inner frame body 21 and the outer frame body 11 can be connected. The protruding plate 217 protrudes inward relative to the first side plate 112, thereby enhancing the structural strength of the second support part 212 and improving the support strength of the second support part 212. The second support part 212 and the first side plate 112 are separated by an inner and outer gap, so that a cavity can be formed between the first side plate 112, the first base plate 113, the second base plate 215, the support plate 216 and the protruding plate 217. The cavity can limit the corner bracket, thereby facilitating the corner bracket to extend into the cavity and thus facilitating the fixed installation of the photovoltaic module frame 100.

[0047] In addition, such as Figures 1-3 As shown, the first top plate 111 includes a first horizontal plate 114 and a first inclined plate 115. The first horizontal plate 114 is connected to the first side plate 112, and the first inclined plate 115 is connected to the first horizontal plate 114 and inclined relative to the first horizontal plate 114. The second top plate 213 includes a second horizontal plate 218 and a second inclined plate 219. The second horizontal plate 218 is connected to the second side plate 214 and is attached to the inner side of the first horizontal plate 114. The second inclined plate 219 is connected to the second horizontal plate 218 and inclined relative to the second horizontal plate 218. The second inclined plate 219 is connected to the first inclined plate 115 and is attached to the inner side of the first inclined plate 115.

[0048] In other words, the first horizontal plate 114 and the first inclined plate 115 constitute the main structure of the first top plate 111, and the second horizontal plate 218 and the second inclined plate 219 constitute the main structure of the second top plate 213. The first inclined plate 115 is connected to one end of the first horizontal plate 114, and the second inclined plate 219 is connected to one end of the second horizontal plate 218. Moreover, the first inclined plate 115 is inclined at a certain angle relative to the first horizontal plate 114, and the second inclined plate 219 is inclined at a certain angle relative to the second horizontal plate 218. This facilitates the fitting of the first inclined plate 115 and the second inclined plate 219, as well as the fitting of the first horizontal plate 114 and the second horizontal plate 218.
