Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a photovoltaic frame and a photovoltaic module. Background Technology

[0002] Photovoltaic modules typically consist of laminates, junction boxes, and frames. After the photovoltaic modules are manufactured, they need to be packaged. Currently, multiple photovoltaic modules are usually stacked in the packaging box along their thickness direction.

[0003] Because individual photovoltaic modules have a certain thickness, and stacked photovoltaic modules are very thick, the number of stacked photovoltaic modules that can be accommodated in a single packaging box is relatively small. Therefore, an increased number of packaging boxes is needed to transport the intended number of photovoltaic modules, thus increasing transportation costs.

[0004] Therefore, how to increase the number of photovoltaic modules that can be accommodated in a single packaging box, reduce the number of packaging boxes used, and lower transportation costs remains a pressing technical problem for the industry. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic frame and photovoltaic module, which can increase the number of photovoltaic modules that can be accommodated in a single packaging box, reduce the number of packaging boxes used, and reduce transportation costs.

[0006] To achieve the above objectives, in a first aspect, this utility model provides a photovoltaic frame. The photovoltaic frame includes a first frame and a second frame. The first frame includes a first side plate and a bottom plate spaced apart along the height direction of the photovoltaic frame; the bottom plate is used to connect and fix a laminate; the second frame is connected to the first frame; along the width direction of the photovoltaic frame, the second frame is located on one side of the first frame; the first side plate and the first connecting plate included in the second frame are parallel to each other, and both the first side plate and the first connecting plate are inclined relative to the height direction of the photovoltaic frame; the bottom plate is connected to the first connecting plate; the two photovoltaic frames are stacked, with the first side plate at least abutting against the first connecting plate located below the bottom plate, and the total thickness of the two stacked photovoltaic frames is less than the total thickness of the two photovoltaic frames before stacking.

[0007] In the photovoltaic frame provided by this utility model, the base plate is used to connect and fix the laminate, and the base plate is connected to the first connecting plate; furthermore, when two photovoltaic frames are stacked, the first side plate is at least in contact with the first connecting plate located below the base plate. Therefore, when two photovoltaic frames are stacked, the laminate fixed to the upper photovoltaic frame and the first connecting plate located at least below the base plate are both located within the accommodating space of the lower photovoltaic frame. Further, since the total thickness of the two stacked photovoltaic frames in this application is less than the total thickness of the two photovoltaic frames before stacking, the total thickness of the two stacked photovoltaic modules including the laminate and the photovoltaic frame provided in this application is less than the total thickness of the two photovoltaic modules including the laminate and the photovoltaic frame provided in this application before stacking. Therefore, for the same number of photovoltaic modules, compared to the prior art, the number of photovoltaic modules made from the photovoltaic frame provided in this application can be increased in the same packaging box. Based on this, for the same number of photovoltaic modules, the photovoltaic modules made from the photovoltaic frame provided in this application can reduce the number of packaging boxes used and reduce transportation costs.

[0008] In one implementation, the first frame further includes a second side plate and a third side plate, which are arranged opposite to and spaced apart along the width direction of the photovoltaic frame. The first side plate, the second side plate, a portion of the first connecting plate, the bottom plate, and the third side plate enclose a first cavity; the first side plate has a first included angle with the height direction of the photovoltaic frame, the first included angle being greater than or equal to 30° and less than or equal to 60°.

[0009] When the above technical solution is adopted, when the first included angle is greater than or equal to 30°, it can be ensured that after two photovoltaic modules are stacked, the first side plate included in the lower photovoltaic frame can provide stable support for the upper photovoltaic module. This avoids the situation where the first side plate included in the lower photovoltaic frame is too weak to support the upper photovoltaic module due to an excessively small first included angle, thus ensuring the safety and stability of the two photovoltaic modules. When the first included angle is less than or equal to 60°, the total thickness of the two stacked photovoltaic frames can meet the actual requirements, thereby increasing the number of photovoltaic modules that can be accommodated in a single packaging box, reducing the number of packaging boxes used, and lowering transportation costs. In addition, the aforementioned first cavity can be used to install corner brackets, which are used to fix adjacent photovoltaic frames together. Furthermore, since the first cavity is close to the base plate, and the laminate is fixedly connected to the base plate, when the corner brackets are installed and fixed in the first cavity, the corner brackets can provide support and connection, thereby improving the stability of the connection between adjacent photovoltaic frames and improving the stability and safety of the photovoltaic modules.

[0010] In one implementation, the second frame includes a top plate, a second connecting plate, and a first connecting plate connected in sequence. Along a direction away from the second connecting plate, the first connecting plate includes a first segment, a second segment, and a third segment. The second side plate, the top plate, the second connecting plate, and the first segment enclose a second cavity. The free end of the top plate connects to the junction of the first and second side plates. The bottom plate connects to the junction of the second and third segments; the second side plate connects to the junction of the first and second segments. Along the height direction of the photovoltaic frame, the third segment is located below the bottom plate, and the bottom plate and the top plate are offset. Both the second side plate and the second connecting plate are parallel to the height direction of the photovoltaic frame.

[0011] With the above technical solution, both the second side plate and the second connecting plate are parallel to the height direction of the photovoltaic frame. In this case, the second side plate and the second connecting plate can provide more stable support for the entire photovoltaic frame, ensuring its stability and thus the stability of the photovoltaic module including the photovoltaic frame. Furthermore, the aforementioned second cavity can also be used to install corner brackets, which are used to fix two adjacent photovoltaic frames together. As described above, corner brackets can be installed not only in the first cavity but also in the second cavity, offering diverse installation positions, increasing selectivity, and expanding the applicability and application scenarios of the photovoltaic frame. Furthermore, when corner brackets are simultaneously installed and fixed in both the first and second cavities, the stability of the connection between two adjacent photovoltaic frames can be further improved, thereby further enhancing the stability and safety of the photovoltaic module. Furthermore, since the second side panel connects to the junction of the first and second segments, when the two photovoltaic frames are stacked, if the junction of the first and second segments of the upper photovoltaic frame coincides with the second side panel of the lower photovoltaic frame, the upper photovoltaic frame will embed itself into the lower photovoltaic frame, achieving a mating fit and thus enhancing the robustness of the connection between the two photovoltaic frames. Compared to the prior art where the two photovoltaic frames are merely attached to each other but not mated, the photovoltaic frames in this application can reduce the mutual sliding and tipping of photovoltaic modules during transportation, increasing safety and reliability.

[0012] In one implementation, the first frame further includes a fourth side panel. The fourth side panel is connected to both the first and third side panels. A second included angle, which is acute and greater than the first included angle, is formed between the fourth side panel and the photovoltaic frame along its height direction. A third included angle, which is obtuse, is formed between the third and fourth side panels.

[0013] When the above technical solution is adopted, if the weight of the upper photovoltaic module is too large or the upper photovoltaic module is moved towards the photovoltaic module below it by an external force after the two photovoltaic modules are stacked, the upper photovoltaic module or the upper photovoltaic frame will be supported by the fourth side plate (or the junction of the fourth side plate and the third side plate) when it moves to the fourth side plate (or the joint support of the fourth side plate and the third side plate) to prevent it from moving downward and improve the safety of the two photovoltaic modules.

[0014] In one implementation, both the second and third side panels are parallel to the height direction of the photovoltaic frame.

[0015] At this point, the second and third side panels can provide more stable support for the entire photovoltaic frame, ensuring the stability of the photovoltaic frame and thus ensuring the stability of the photovoltaic modules including the photovoltaic frame.

[0016] In one implementation, the photovoltaic frame further includes a support plate. The support plate and the base plate are spaced apart along the height of the photovoltaic frame. The support plate is connected to a first connecting plate, and the first connecting plate, the support plate, and the base plate form a mounting groove.

[0017] When the above technical solution is adopted, the laminate is placed within the mounting groove during actual use. When the laminate is secured within the mounting groove, the installation stability of the laminate and the photovoltaic frame is improved. Alternatively, when sealant is injected into the mounting groove, the combined effect of the mounting groove and the sealant strengthens the fixation of the laminate, improving the installation stability of the laminate and the photovoltaic frame, thereby ensuring the safety of the laminate.

[0018] Secondly, this utility model also provides a photovoltaic module. The photovoltaic module includes a laminate and a photovoltaic frame as described in the above technical solution, with the laminate fixed to a base plate included in the photovoltaic frame.

[0019] The beneficial effects of the photovoltaic module provided by this utility model are the same as those of the photovoltaic frame described in the above technical solution, and will not be repeated here.

[0020] In one implementation, the photovoltaic frame includes a first frame, and the first frame includes a third side panel. The photovoltaic module also includes a junction box. The junction box is integrally formed with any of the photovoltaic frames; the junction box is located on the third side panel.

[0021] With the above technical solution, since the junction box is integrally formed with any photovoltaic frame, it is already fixedly connected to the photovoltaic frame. Therefore, there is no need to use silicone to bond the junction box to the laminate, saving not only the amount of silicone used and the silicone curing time, but also the cost of manual operation and the cost of using fixing clamps during the bonding process. Furthermore, the gaps in the junction box integrally formed with the photovoltaic frame are smaller and fewer (or even non-existent) than the gaps in the assembled junction boxes of the prior art. Therefore, there is no need to inject silicone for moisture isolation into the junction box of this application. Based on this, the amount of silicone used and the silicone curing time are further reduced.

[0022] In one implementation, the height of the junction box is less than or equal to the height of the third side panel.

[0023] With the above technical solution, it is avoided that the height of the junction box is greater than the height of the third side plate, causing part of the junction box to extend beyond the third side plate and be located on the side of the first side plate. This is to prevent the junction box from being damaged by the excessive weight of the photovoltaic module above or by the photovoltaic module above being moved closer to the photovoltaic module below it due to external forces.

[0024] In one implementation, the junction box is located closer to the base plate.

[0025] By adopting the above technical solution, the probability of the junction box being located on one side of the first side panel is reduced or eliminated, so as to avoid the junction box being damaged by the photovoltaic module located above or the photovoltaic frame located above when the photovoltaic module located above is too heavy or when it is moved closer to the photovoltaic module located below it by external force.

[0026] In one implementation, the photovoltaic frame includes an aluminum photovoltaic frame or a plastic photovoltaic frame; the photovoltaic module includes three aluminum photovoltaic frames and one plastic photovoltaic frame. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] To address the aforementioned technical problems, in a first aspect, embodiments of this utility model provide a photovoltaic frame. See also... Figure 1 and Figure 2 The photovoltaic frame includes a first frame 1 and a second frame 2. The first frame 1 includes a first side plate 10 and a bottom plate 11 spaced apart along the height direction H of the photovoltaic frame. The bottom plate 11 is used to connect and fix the laminate 4. The second frame 2 is connected to the first frame 1 and is located on one side of the first frame 1 along the width direction W of the photovoltaic frame. The first side plate 10 and the first connecting plate 22 included in the second frame 2 are parallel to each other, and both the first side plate 10 and the first connecting plate 22 are inclined relative to the height direction H of the photovoltaic frame 3. The bottom plate 11 is connected to the first connecting plate 22; the two photovoltaic frames 3 are stacked, with the first side plate 10 at least in contact with the first connecting plate 22 located below the bottom plate 11. The total thickness of the two stacked photovoltaic frames 3 is less than the total thickness of the two photovoltaic frames 3 before stacking. Note that, see [link to relevant documentation]. Figure 3 and Figure 4 The above stacking can be either flat or vertical.

[0043] For example, the laminate can be fixedly connected to the base plate by adhesive bonding. Furthermore, to increase the contact area between the base plate and the laminate, and to improve the strength of the connection between the base plate and the laminate, the base plate is parallel to the laminate.

[0044] See Figures 1 to 4In the photovoltaic frame provided in this embodiment, the base plate 11 is used to connect and fix the laminate 4, and the base plate 11 is connected to the first connecting plate 22; and when two photovoltaic frames 3 are stacked, the first side plate 10 is at least in contact with the first connecting plate 22 located below the base plate 11. Therefore, when two photovoltaic frames 3 are stacked, the laminate 4 fixed to the upper photovoltaic frame 3 and the first connecting plate 22 located at least below the base plate 11 are both located within the accommodating space M of the lower photovoltaic frame 3. At this time, compared to the prior art where the ends of two stacked photovoltaic frames abut each other, and the accommodating space M of the lower photovoltaic frame 3 is idle and cannot be utilized, in this application, the laminate 4 fixed to the upper photovoltaic frame 3 and the first connecting plate 22 located at least below the base plate 11 fully utilize the accommodating space M of the lower photovoltaic frame 3. Furthermore, since the total thickness of the two stacked photovoltaic frames 3 in this application is less than the total thickness of the two photovoltaic frames 3 before stacking, the total thickness of the two stacked photovoltaic modules 6, including the laminate 4 and the photovoltaic frames 3 provided in this application, is also less than the total thickness of the two photovoltaic modules 6 before stacking, resulting in a lower space occupancy rate for the stacked photovoltaic modules 6. Therefore, for the same packaging box, compared to the prior art, the number of photovoltaic modules 6 made from the photovoltaic frames 3 provided in this application can be increased within the packaging box. Based on this, for the same number of photovoltaic modules 6, using the photovoltaic frames 3 provided in this application can reduce the number of packaging boxes used, thus reducing transportation costs. Furthermore, for factory buildings of the same height, the total number of stacked photovoltaic modules 6 made from the photovoltaic frames 3 provided in this application is greater than the total number of stacked conventional photovoltaic modules, increasing the number of photovoltaic modules that can be accommodated within the factory building and reducing the storage costs of the photovoltaic modules.

[0045] In practical use, the total thickness of the two stacked photovoltaic modules 6, including the laminate 4 and the photovoltaic frame 3 provided in this application, is 3 / 4 of the total thickness of the two unstacked photovoltaic modules 6, including the laminate 4 and the photovoltaic frame 3 provided in this application. This reduces the space occupancy rate of the stacked photovoltaic modules 6. In the prior art, when packaging multiple photovoltaic modules 6, 36 photovoltaic modules are placed in one tray, with each photovoltaic module including a photovoltaic frame with a height of 30 mm. However, while keeping the height of the photovoltaic frame unchanged, when packaging photovoltaic modules 6 made using the photovoltaic frame 3 provided in this application, the number of photovoltaic modules per tray can be increased to 46. Therefore, this application increases the number of photovoltaic modules that can be accommodated in a single packaging box, reduces the number of packaging boxes used, and lowers transportation costs.

[0046] As one possible implementation, see Figure 1The first frame 1 further includes a second side plate 12 and a third side plate 13, which are arranged opposite to and spaced apart along the width direction W of the photovoltaic frame. The first side plate 10, the second side plate 12, a portion of the first connecting plate 22, the bottom plate 11, and the third side plate 13 enclose a first cavity; the first side plate 10 and the photovoltaic frame have a first included angle A in the height direction H, which is greater than or equal to 30° and less than or equal to 60°. For example, the first included angle A can be 30°, 35°, 40°, 45°, 50°, 55°, 58°, or 60°, etc.

[0047] When using the above technical solution, see Figure 1 and Figure 2 When the first included angle A is greater than or equal to 30°, it ensures that after two photovoltaic modules 6 are stacked, the first side plate 10 included in the lower photovoltaic frame 3 can provide stable support for the upper photovoltaic module 6. This avoids the situation where the first side plate 10 included in the lower photovoltaic frame 3 has insufficient support force to support the upper photovoltaic module 6 due to an excessively small first included angle A, thus ensuring the safety and stability of the two photovoltaic modules 6. When the first included angle A is less than or equal to 60°, the total thickness of the two stacked photovoltaic frames 3 meets the actual requirements, thereby increasing the number of photovoltaic modules 6 that can be accommodated in a single packaging box, reducing the number of packaging boxes used, and lowering transportation costs. In addition, the aforementioned first cavity can be used to install corner brackets, which are used to fix two adjacent photovoltaic frames 3 together. Furthermore, since the first cavity is close to the base plate 11, and the laminate 4 is fixedly connected to the base plate 11, when the corner bracket is installed and fixed in the first cavity, the corner bracket can provide support and connection, thereby improving the stability of the connection between two adjacent photovoltaic frames 3 and improving the stability and safety of the photovoltaic module 6.

[0048] In some embodiments, see Figure 1 The height of the third side plate 13 is less than the height of the second side plate 12. Along the height direction H of the photovoltaic frame 3, the cross-section of the first cavity is trapezoidal or trapezoidal.

[0049] In some embodiments, the specific values ​​of the height of the second side panel and the height of the third side panel are related to the height of the photovoltaic module and the number of photovoltaic modules stacked. Therefore, the height of the second side panel and the height of the third side panel are not specifically limited here, and can be set according to actual needs.

[0050] In one alternative approach, the first side panel is the primary load-bearing and mating component of the stacked photovoltaic modules. Given its primary load-bearing function, its length and thickness need to be guaranteed. Specifically, the vertical load needs to be calculated based on the product design and the weight of a single photovoltaic module. The product design affects the number of modules that can be stacked on a single rack, and the weight of a single photovoltaic module is also a crucial factor affecting the calculation of the vertical load. Therefore, the length, width, and thickness of the first side panel are not specifically limited here and can be set according to actual needs.

[0051] In one alternative approach, see Figure 1 and Figure 2 The second frame 2 includes a top plate 20, a second connecting plate 21, and a first connecting plate 22 connected in sequence. Along the direction away from the second connecting plate 21, the first connecting plate 22 includes a first segment 220, a second segment 221, and a third segment 222. The second side plate 12, top plate 20, second connecting plate 21, and first segment 220 enclose a second cavity. The free end of the top plate 20 is connected to the junction of the first side plate 10 and the second side plate 12. The bottom plate 11 is connected to the junction of the second segment 221 and the third segment 222; the second side plate 12 is connected to the junction of the first segment 220 and the second segment 221. Along the height direction H of the photovoltaic frame 3, the third segment 222 is located below the bottom plate 11. At this time, the laminate 4 can not only be bonded to the bottom plate 11, but also its side can be bonded to the third segment 222 included in the first connecting plate 22. Along the height direction H of the photovoltaic frame 3, the bottom plate 11 and the top plate 20 are staggered. The second side plate 12 and the second connecting plate 21 mentioned above are both parallel to the height direction H of the photovoltaic frame 3.

[0052] When using the above technical solution, see Figure 1 and Figure 2The second side plate 12 and the second connecting plate 21 are both parallel to the height direction H of the photovoltaic frame 3. In this configuration, the second side plate 12 and the second connecting plate 21 provide more stable support for the photovoltaic frame 3 as a whole, ensuring the stability of the photovoltaic frame 3 and thus the stability of the photovoltaic module 6 including the photovoltaic frame 3. Furthermore, the aforementioned second cavity can also be used to install corner brackets, which are used to fix two adjacent photovoltaic frames 3 together. As described above, corner brackets can be installed not only in the first cavity but also in the second cavity, offering various installation positions, increasing selectivity, and expanding the applicability and application scenarios of the photovoltaic frame 3. Moreover, when corner brackets are simultaneously installed and fixed in both the first and second cavities, the stability of the connection between two adjacent photovoltaic frames 3 can be further improved, thereby further enhancing the stability and safety of the photovoltaic module 6. Furthermore, since the second side plate 12 connects to the junction of the first segment 220 and the second segment 221, when two photovoltaic frames 3 are stacked, if the junction of the first segment 220 and the second segment 221 of the upper photovoltaic frame 3 coincides with the second side plate 12 of the lower photovoltaic frame 3, the upper photovoltaic frame 3 is embedded into the lower photovoltaic frame 3, thus achieving a fit and enhancing the connection strength of the two photovoltaic frames 3. Compared to the prior art where two photovoltaic frames 3 are simply attached to each other but not fitted together, the photovoltaic frames 3 of this application can reduce the mutual sliding and tipping of photovoltaic modules 6 during transportation, increasing safety and reliability and facilitating production turnover. For example, during turnover and transportation, adjacent photovoltaic frames 3 in flat-stacking photovoltaic modules 6 are fitted together, making it less likely for the flat-stacking photovoltaic modules 6 to slip off.

[0053] In some embodiments, see Figure 1 Along the height direction H of the photovoltaic frame 3, the second segment 221 and the third segment 222 included in the first connecting plate 22 are opposite to each other and are distributed at intervals.

[0054] See Figure 1 The length of the first connecting plate 22 is greater than the length of the first side plate 10, and the second segment 221 and the third segment 222 are located below the first side plate 10. When two photovoltaic frames 3 or two photovoltaic modules 6 are stacked, the first side plate 10 of the upper photovoltaic module 6 is attached to the third segment 222 of the first connecting plate 22 of the lower photovoltaic module 6; or, the first side plate 10 of the upper photovoltaic module 6 is attached to the second segment 221 and the third segment 222 of the first connecting plate 22 of the lower photovoltaic module 6.

[0055] In some embodiments, see Figure 2In the actual stacking process, the upper photovoltaic frame 3 is embedded in the lower photovoltaic frame 3 to achieve a fitting. Furthermore, the first side plate 10 of the upper photovoltaic module 6 is attached to the second segment 221 and the third segment 222 of the first connecting plate 22 of the lower photovoltaic module 6.

[0056] In some embodiments, see Figure 1 Along the height direction H of the photovoltaic frame 3, the cross section of the second cavity is trapezoidal or trapezoidal.

[0057] In some embodiments, see Figure 2 In the same photovoltaic frame 3, the distance between two relatively distributed second side plates 12 is equal to the distance between the two relatively "intersections of the second segment 221 and the third segment 222".

[0058] As one possible implementation, see Figure 1 The first frame 1 also includes a fourth side plate 14. The fourth side plate 14 is connected to the first side plate 10 and the third side plate 13 respectively; the fourth side plate 14 and the photovoltaic frame 3 have a second included angle B in the height direction H, the second included angle B is an acute angle and is greater than the first included angle A. The third side plate 13 and the fourth side plate 14 have a third included angle C, the third included angle C is an obtuse angle.

[0059] When using the above technical solution, see Figure 1 and Figure 2 When two photovoltaic modules 6 are stacked, if the weight of the upper photovoltaic module 6 is too large or the upper photovoltaic module 6 is moved towards the photovoltaic module 6 below it by an external force, when the upper photovoltaic module 6 or the upper photovoltaic frame 3 moves to the fourth side plate 14 (or to the junction of the fourth side plate 14 and the third side plate 13), the upper photovoltaic module 6 or the upper photovoltaic frame 3 will be supported by the fourth side plate 14 (or by the combined support of the fourth side plate 14 and the third side plate 13) to prevent it from moving downward and improve the safety of the two photovoltaic modules 6.

[0060] In one alternative approach, see Figure 1 The second included angle B is greater than 60°. For example, the second included angle B can be 61°, 62°, 63°, 64°, 65°, 66°, 70°, 75°, 80°, 85° or 89°, etc.

[0061] In one alternative approach, the third included angle C is greater than 90° and less than 120°. For example, the third included angle C can be 91°, 93°, 95°, 100°, 105°, 110°, 115°, or 119°, etc.

[0062] In one alternative approach, see Figure 1 The ratio between the width W1 of the first side plate 10 and the width W2 of the fourth side plate 14 can be set according to the actual situation, and no specific limit is made here.

[0063] In one alternative approach, see Figure 1 The second side plate 12 and the third side plate 13 are both parallel to the height direction H of the photovoltaic frame 3. At this time, the second side plate 12 and the third side plate 13 can provide more stable support for the photovoltaic frame 3 as a whole, ensuring the stability of the photovoltaic frame 3, thereby ensuring the stability of the photovoltaic module 6 including the photovoltaic frame 3.

[0064] In one alternative approach, see Figure 1 The ratio of the height H1 of the third side plate 13 to the maximum vertical distance L1 between the first side plate 10 and the bottom plate 11 can be set according to the actual situation, and no specific limitation is made here.

[0065] In one alternative approach, see Figure 1 The photovoltaic frame 3 also includes a support plate 30. Along the height direction H of the photovoltaic frame 3, the support plate 30 and the base plate 11 are spaced apart. The support plate 30 is connected to the first connecting plate 22, and the first connecting plate 22, the support plate 30, and the base plate 11 form a mounting groove 31. Specifically, the support plate 30 is connected to the third segment 222 included in the first connecting plate 22, and the support plate 30, the base plate 11, and the third segment 222 included in the first connecting plate 22 form the mounting groove 31.

[0066] When the above technical solution is adopted, the laminate 4 is disposed within the mounting groove 31 during actual use. When the laminate 4 is secured within the mounting groove 31, the installation firmness of the laminate 4 and the photovoltaic frame 3 is improved. Alternatively, when sealant is injected into the mounting groove 31, the combined action of the mounting groove 31 and the sealant strengthens the fixation of the laminate 4, improving the installation firmness of the laminate 4 and the photovoltaic frame 3, thereby ensuring the safety of the laminate 4.

[0067] As one possible implementation, the photovoltaic frame described above can be an aluminum photovoltaic frame or a plastic photovoltaic frame.

[0068] When the photovoltaic frame is made of plastic, the plastic photovoltaic frame has insulating properties, which can avoid potential-induced degradation (PID), reduce the risk of leakage, and at the same time eliminate the need for additional grounding treatment, simplifying the installation process.

[0069] Secondly, this utility model embodiment also provides a photovoltaic module. See [link to relevant documentation]. Figure 2The photovoltaic module 6 includes a laminate 4 and a photovoltaic frame 3 as described in the above technical solution. The laminate 4 is fixed to the base plate 11 included in the photovoltaic frame 3.

[0070] The beneficial effects of the photovoltaic module provided in this embodiment are the same as those of the photovoltaic frame described in the above technical solution, and will not be repeated here.

[0071] As one possible implementation, see Figures 5 to 7 The photovoltaic frame 3 includes a first frame 1, and the first frame 1 includes a third side plate 13. The photovoltaic module 6 also includes a junction box 5. The junction box 5 is integrally formed with any of the photovoltaic frames 3; the junction box 5 is located on the third side plate 13 included in the photovoltaic frame 3, and the junction box 5 abuts against or is spaced apart from the laminate 4. It should be noted that the junction box 5 is electrically connected to the internal structure of the laminate 4. As for the specific connection method and wiring method between the junction box 5 and the laminate 4, no specific limitation is made here, as long as the photovoltaic module 6 can work normally.

[0072] With the above technical solution, since the junction box 5 is integrally formed with any photovoltaic frame 3, the junction box 5 is already fixedly connected to the photovoltaic frame 3. Therefore, it is not necessary to use silicone to bond the junction box 5 to the laminate 4, which not only saves the amount of silicone used and the silicone curing time, but also saves the cost of manual operation and the cost of using fixing clamps during the bonding process. Furthermore, the gaps of the junction box 5 integrally formed with the photovoltaic frame 3 are smaller and fewer in number (or even non-existent) than the gaps of the assembled junction box 5 in the prior art. Therefore, it is not necessary to inject silicone for moisture isolation into the junction box 5 in this application. Based on this, the amount of silicone used and the silicone curing time are further reduced.

[0073] As one possible implementation, the photovoltaic frame described above can be an aluminum photovoltaic frame or a plastic photovoltaic frame.

[0074] As one possible implementation, when the junction box is made of plastic, the photovoltaic frame component integrally formed with the junction box is a plastic photovoltaic frame.

[0075] In some embodiments, see Figure 7 The photovoltaic module 6 includes two opposing and spaced-apart long photovoltaic frames and two opposing and spaced-apart short photovoltaic frames. The junction box 5 is disposed on one of the short photovoltaic frames. The photovoltaic frame 3 integrally formed with the junction box 5 is a plastic photovoltaic frame, and the other three photovoltaic frames 3 are aluminum photovoltaic frames.

[0076] With the above technical solution, this application adopts a lightweight design, namely, a combination of three aluminum photovoltaic frames and one plastic photovoltaic frame. The three aluminum photovoltaic frames ensure the overall load-bearing capacity of the photovoltaic module, while the weight of the plastic photovoltaic frame is only about 75% of that of aluminum alloy, which can significantly reduce the overall weight of the photovoltaic module. This is particularly suitable for scenarios such as rooftop photovoltaics where installation weight is sensitive. The lightweight design also reduces the load-bearing requirements of the support structure for the photovoltaic module.

[0077] In one alternative approach, see Figure 1 and Figure 6 The height H2 of junction box 5 is less than or equal to the height H1 of the third side plate 13.

[0078] When using the above technical solution, see Figure 1 , Figure 2 and Figure 6 To prevent the junction box 5 from being located on the side of the first side plate 10 where part of the junction box 5 exceeds the height H1 of the third side plate 13 due to the height H2 of the junction box 5 being greater than the height H1 of the third side plate 13, and to prevent the junction box 5 from being damaged by the upper photovoltaic module 6 or the upper photovoltaic frame 3 when the upper photovoltaic module 6 is too heavy or when it is moved closer to the lower photovoltaic module 6 by external force.

[0079] In some embodiments, the height of the junction box is generally 15mm.

[0080] In some embodiments, see Figure 6 Junction box 5 is closer to the base plate 11.

[0081] With the above technical solution, the probability of the junction box 5 being located on one side of the first side plate 10 is reduced or eliminated, so as to avoid the junction box 5 being crushed by the photovoltaic module 6 located above or the photovoltaic frame 3 located above when the photovoltaic module 6 located above is too heavy or when it is moved closer to the photovoltaic module 6 located below it by external force.

[0082] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0083] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
