[0036] 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.

[0037] 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.

[0038] Reference Figures 1-2As shown, the frame 100 of the photovoltaic module according to the first aspect of this utility model includes an outer frame 10 and an inner frame 20. The outer frame 10 includes an outer frame body 101, a first engaging portion 102 and a second engaging portion 103. The first engaging portion 102 is connected to the second engaging portion 103 and is bent relative to the second engaging portion 103. The second engaging portion 103 is connected to one end of the outer frame body 101 and is bent relative to the outer frame body 101. The second engaging portion 103 and the outer frame body 101 together form an engaging groove 11. 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 support portion 22 and a third engaging portion 23. One end of the inner frame 21 is connected to the other end of the outer frame body 101, and one end of the inner frame body 21 is bent relative to the outer frame body 101. The inner frame body 21 forms an installation groove 30 for installing photovoltaic modules. One end of the support part 22 is connected to the other end of the inner frame body 21, and one end of the support part 22 is bent relative to the inner frame body 21. The third engagement part 23 is connected to the other end of the support part 22, and the third engagement part 23 is bent relative to the support part 22. The third engagement part 23 is located in the engagement groove 11. The first engagement part 102, the support part 22 and the outer frame body 101 form at least a three-layer stacked structure 40, and the second engagement part 103, the third engagement part 23, the support part 22 and the outer frame body 101 form at least a four-layer stacked structure 50.

[0039] Specifically, there are various ways to trim the edges of traditional photovoltaic modules. However, the riveting position and number of rivetings have a significant impact on the performance of the frame, and the number of trimming layers has a significant impact on the load performance of the photovoltaic module.

[0040] Therefore, the frame 100 of the photovoltaic module needs to be optimized. The inner frame 20 is set inside the outer frame 10, and the inner frame 20 and the outer frame 10 are integrally formed. In this way, the frame 100 of the photovoltaic module is integrally bent and formed, which can not only improve the overall strength of the frame 100, but also improve the production efficiency of the frame 100.

[0041] The outer frame 10 of the photovoltaic module is mainly composed of an outer frame body 101, a first interlocking part 102, and a second interlocking part 103. The first interlocking part 102 is bent downward relative to the second interlocking part 103, which can increase multiple riveting positions. This facilitates the surface-to-surface contact of the first interlocking part 102, the support part 22, and the outer frame body 101 to form at least a three-layer stacked structure 40. Thus, a three-layer stacked structure 40 is formed at the first interlocking part 102, which can increase the strength of the first interlocking part 102. To prevent the first interlocking part 102 from loosening, the first interlocking part 102, the support part 22, and the outer frame body 101 are then riveted together, which can make the connection between the first interlocking part 102, the support part 22, and the outer frame body 101 more stable.

[0042] Furthermore, the second engagement portion 103, the third engagement portion 23, the support portion 22, and the outer frame body 101 can be surface-to-surface to form at least a four-layer stacked structure 50. This not only improves the strength of the second engagement portion 103 but also allows the second engagement portion 103 to form a finishing edge of the four-layer stacked structure 50. Then, the second engagement portion 103, the third engagement portion 23, the support portion 22, and the outer frame body 101 are riveted together, thus further increasing the finishing edge positions and the number of layers. Moreover, the arrangement of multiple stacked structures can increase the riveting positions and the number of riveting layers, thereby further improving the strength of the finishing edge of the frame 100.

[0043] Furthermore, the second occlusal portion 103 and the outer frame body 101 together form an occlusal groove 11, which can provide bending space for the third occlusal portion 23, thereby allowing the third occlusal portion 23 to be located within the occlusal groove 11.

[0044] Therefore, the first interlocking part 102, the support part 22 and the outer frame body 101 of the photovoltaic module frame 100 can be bonded together to form at least a three-layer stacked structure 40, and the second interlocking part 103, the third interlocking part 23, the support part 22 and the outer frame body 101 can be bonded together to form at least a four-layer stacked structure 50. This can not only increase the number of layers and strength of the frame 100 at different edge closing positions, but also increase the edge closing positions, thereby improving the strength of the frame 100, and can further increase the number of riveting positions and layers on the frame 100.

[0045] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the parts of the first engagement portion 102 and the support portion 22 corresponding to the first engagement portion 102 are riveted together with the parts of the outer frame body 101 corresponding to the first engagement portion 102, and / or the parts of the second engagement portion 103, the third engagement portion 23 and the support portion 22 corresponding to the third engagement portion 23 are riveted together with the parts of the outer frame body 101 corresponding to the third engagement portion 23.

[0046] In this process, the parts of the first engaging portion 102, the supporting portion 22 corresponding to the first engaging portion 102, and the outer frame body 101 corresponding to the first engaging portion 102 are first pressed together by mechanical equipment. The parts of the first engaging portion 102, the supporting portion 22 corresponding to the first engaging portion 102, and the outer frame body 101 corresponding to the first engaging portion 102 are all provided with mounting holes. Rivets can be sequentially inserted into the parts of the first engaging portion 102, the supporting portion 22 corresponding to the first engaging portion 102, and the outer frame body 101 corresponding to the first engaging portion 102 for fixed connection, thereby preventing the parts of the first engaging portion 102, the supporting portion 22 corresponding to the first engaging portion 102, and the outer frame body 101 corresponding to the first engaging portion 102 from becoming loose.

[0047] Similarly, the parts of the second engagement portion 103, the third engagement portion 23, and the support portion 22 corresponding to the third engagement portion 23, and the parts of the outer frame body 101 corresponding to the third engagement portion 23 are first pressed together by mechanical equipment. The parts of the second engagement portion 103, the third engagement portion 23, and the support portion 22 corresponding to the third engagement portion 23, and the parts of the outer frame body 101 corresponding to the third engagement portion 23 are all provided with mounting holes. Rivets can be sequentially inserted into the parts of the second engagement portion 103, the third engagement portion 23, the support portion 22 corresponding to the third engagement portion 23, and the parts of the outer frame body 101 corresponding to the third engagement portion 23, thereby preventing the parts of the second engagement portion 103, the third engagement portion 23, the support portion 22 corresponding to the third engagement portion 23, and the parts of the outer frame body 101 corresponding to the third engagement portion 23 from becoming loose.

[0048] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a bending portion 60 is provided between the first occlusal portion 102 and the second occlusal portion 103. The bending portion 60 is generally arc-shaped, or a first transition arc 70 is provided between the bending portion 60 and the first occlusal portion 102, and a second transition arc 71 is provided between the bending portion 60 and the second occlusal portion 103.

[0049] The bending portion 60 facilitates the connection between the first engagement portion 102 and the support portion 22. Multiple bending portions 60 can be provided between the first engagement portion 102 and the second engagement portion 103. Each bending portion 60 can form a multi-layered structure, which increases the number and location of riveting, thereby improving the strength of the frame 100.

[0050] Furthermore, such as Figure 3As shown, a first transition arc 70 is provided between the bent portion 60 and the first engagement portion 102, which can make the connection between the bent portion 60 and the first engagement portion 102 smoother, thereby avoiding stress concentration between the bent portion 60 and the first engagement portion 102.

[0051] Similarly, a second transition arc 71 is provided between the bent portion 60 and the second engagement portion 103, which can make the connection between the bent portion 60 and the second engagement portion 103 smoother, thereby avoiding stress concentration between the bent portion 60 and the second engagement portion 103.

[0052] According to some embodiments of this utility model, such as Figure 1 As shown, the width of the first occlusal portion 102 is d1, the width of the second occlusal portion 103 is d2, and d1 and d2 satisfy the relationship: 0.5d2≤d1≤0.8d2, and / or the width of the third occlusal portion 23 is d3, and d2 and d3 satisfy the relationship: 0<d3≤d2.

[0053] The width d1 of the first biting part 102 can be half the width d1 of the second biting part 103. In this way, the width d1 of the second biting part 103 is greater than the width d1 of the first biting part 102, which can increase the space between the second biting part 103 and the outer frame 10 to form the biting groove 11. Thus, multiple stacked structures can be formed in the biting groove 11, such as a three-layer stacked structure 40, a four-layer stacked structure 50, and a five-layer stacked structure.

[0054] Moreover, the width d1 of the first biting part 102 is smaller than the width d2 of the second biting part 103, which not only allows the first biting part 102 to be finished, but also reduces costs.

[0055] Furthermore, the width d3 of the third biting part 23 is smaller than the width d2 of the second biting part 103, so that the third biting part 23 can be located in the biting groove 11, and the second biting part 103 can wrap around the third biting part 23, thereby facilitating the formation of a four-layer stacked structure 50 of the second biting part 103, the third biting part 23, the support part 22 and the outer frame body 101.

[0056] According to some embodiments of this utility model, such as Figure 2 As shown, the sum of the widths of the first biting part 102 and the second biting part 103 is d4, and the width of the support part 22 is d5. d4 and d5 satisfy the relationship: 0.3d5≤d4≤0.8d5.

[0057] The sum of the widths d4 of the first biting part 102 and the second biting part 103 can be 0.3 times the width d5 ​​of the support part 22. This can increase the contact area between the first biting part 102 and the support part 22, thereby increasing the strength of the connection between the first biting part 102 and the support part 22.

[0058] Alternatively, the sum of the widths d4 of the first biting portion 102 and the second biting portion 103 can be 0.8 times the width d5 ​​of the support portion 22, which can further increase the contact area between the first biting portion 102 and the support portion 22, thereby further increasing the strength of the connection between the first biting portion 102 and the support portion 22.

[0059] According to some embodiments of this utility model, such as Figure 2 As shown, the outer frame body 101 includes: a first top plate 1011, a first side plate 1012, and a first bottom plate 1013. The first side plate 1012 is bent and connected between the first top plate 1011 and the first bottom plate 1013. The first engagement part 102, the part of the support part 22 corresponding to the first engagement part 102, and the part of the first bottom plate 1013 corresponding to the first engagement part 102 are surface-to-surface, thereby forming a three-layer stacked structure 40. The second engagement part 103, the third engagement part 23, the part of the support part 22 corresponding to the third engagement part 23, and the part of the first bottom plate 1013 corresponding to the third engagement part 23 are surface-to-surface, thereby forming a four-layer stacked structure 50.

[0060] In this structure, the parts of the first engagement portion 102 and the support portion 22 corresponding to the first engagement portion 102 and the parts of the first base plate 1013 corresponding to the first engagement portion 102 are in surface-to-surface contact, thereby forming a three-layer stacked structure 40. This increases the contact area between them, reduces the stress, avoids stress concentration, prevents cracks, and increases the strength of the edge frame 100 at the engagement point.

[0061] Similarly, the portions of the second engagement portion 103, the third engagement portion 23, and the support portion 22 corresponding to the third engagement portion 23 are surface-to-surface fitted with the portions of the first base plate 1013 corresponding to the third engagement portion 23, thereby forming a four-layer stacked structure 50. This increases the contact area between them, reduces the stress, avoids stress concentration, prevents cracking, and further increases the strength of the edge frame 100 at the engagement point.

[0062] According to some embodiments of this utility model, such as Figure 2As shown, the inner frame body 21 includes a mounting part 211 and a connecting part 212. The mounting part 211 is connected to the first top plate 1011 and is bent relative to the first top plate 1011. The mounting part 211 has a mounting groove 30. The connecting part 212 is bent and connected between the mounting part 211 and the support part 22. The connecting part 212 abuts against the first bottom plate 1013 and is spaced apart from the first side plate 1012. A cavity 80 is formed between the first side plate 1012, the first bottom plate 1013, the mounting part 211 and the connecting part 212. The cavity 80 is used to install corner brackets.

[0063] The inner frame body 21 is mainly composed of a mounting part 211 and a connecting part 212. The mounting groove 30 formed by the mounting part 211 facilitates the installation and fixing of the photovoltaic module. In addition, the connecting part 212 is located between the mounting part 211 and the supporting part 22, thereby providing support for the connection between the mounting part 211 and the supporting part 22.

[0064] Furthermore, a cavity 80 is formed between the first side plate 1012, the first bottom plate 1013, the mounting part 211 and the connecting part 212, which facilitates the insertion of corner brackets and thus facilitates the assembly of the four-sided frame 100 of the photovoltaic panel.

[0065] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the mounting part 211 includes: a second top plate 2111, a second side plate 2112, and a second bottom plate 2113. The second top plate 2111 is connected to one end of the first top plate 1011, and the second top plate 2111 is bent relative to the first top plate 1011. One end of the second side plate 2112 is connected to the other end of the first top plate 1011, and the second side plate 2112 is bent relative to the first top plate 1011. The second top plate 2111 is attached to the first top plate 1011, and the second side plate 2112 is attached to the first side plate 1012. The second bottom plate 2113 is connected to the other end of the second side plate 2112, and the second bottom plate 2113 is bent relative to the second side plate 2112. The second top plate 2111, the second side plate 2112, and the second bottom plate 2113 together form a mounting groove 30. The second bottom plate 2113 is connected to the connecting part 212.

[0066] The second top plate 2111 is bent relative to the first top plate 1011. The second top plate 2111 is located inside the first top plate 1011 and is attached to the first top plate 1011. This can improve the connection strength between the first top plate 1011 and the second top plate 2111.

[0067] Furthermore, the second side plate 2112 is attached to the first side plate 1012, which increases the strength of the first side plate 1012 and the second side plate 2112. Since the second top plate 2111, the second side plate 2112 and the second bottom plate 2113 together form the mounting groove 30, the strength of the mounting groove 30 can be increased, thereby preventing the photovoltaic panel from cracking under pressure.

[0068] According to some embodiments of this utility model, such as Figure 2 As shown, the first top plate 1011 includes a first horizontal plate 10111 and a first inclined plate 10112. The first inclined plate 10112 is connected to the first horizontal plate 10111 and is inclined relative to the first horizontal plate 10111. The second top plate 2111 includes a second horizontal plate 21111 and a second inclined plate 21112. The second inclined plate 21112 is connected to the second horizontal plate 21111 and is inclined relative to the second horizontal plate 21111. The first inclined plate 10112 and the second inclined plate 21112 are connected. The second horizontal plate 21111 is attached to the inner side of the first horizontal plate 10111, and the second inclined plate 21112 is attached to the inner side of the first inclined plate 10112.

[0069] The first inclined plate 10112 is inclined relative to the first horizontal plate 10111, and the angle at which the first inclined plate 10112 is inclined downward relative to the first horizontal plate 10111 does not exceed 15 degrees, so as to block excess silicone from overflowing.

[0070] Furthermore, the second inclined plate 21112 is connected to the second horizontal plate 21111. The second horizontal plate 21111 is set in accordance with the first horizontal plate 10111, and the second inclined plate 21112 is set in accordance with the first inclined plate 10112. The angle at which the second inclined plate 21112 is inclined downward relative to the second horizontal plate 21111 does not exceed 15 degrees. This part works together with the first horizontal plate 10111 and the first inclined plate 10112 to block excess silicone from overflowing, thereby reducing the need for cleaning the front of the photovoltaic module and also reducing labor costs.
