[0042] Figure 1 、 Figure 2 and Figure 3 is a structural schematic diagram of a special-shaped flexible photovoltaic module structure according to an embodiment of the present application, as shown in Figure 1 、 Figure 2 and Figure 3 , the special-shaped flexible photovoltaic module structure comprises a special-shaped flexible photovoltaic module 1 and a fixing structure, wherein the special-shaped flexible photovoltaic module 1 comprises a flexible packaging body 2, and a plurality of crystalline silicon cell pieces 3 with the same size and spliced into a set geometric shape are packaged in the flexible packaging body 2; the fixing structure is arranged at the bottom of the special-shaped flexible photovoltaic module 1, and the special-shaped flexible photovoltaic module 1 is fixedly installed on a surface to be installed through the fixing structure.

[0043] In the embodiment, the plurality of crystalline silicon cell pieces 3 in the special-shaped flexible photovoltaic module 1 can be spliced into various geometric shapes, for example, a heart shape as shown in Figure 1 , a cross shape as shown in Figure 4 , a diamond shape as shown in Figure 5 , and other geometric shapes. Here, they will not be listed one by one. It should be noted that by splicing the plurality of crystalline silicon cell pieces 3 into a heart shape, a cross shape, a diamond shape and other geometric shapes, the special-shaped flexible photovoltaic module 1 can better meet the individual needs of different customers. Whether it is used for commercial buildings or residential decoration, the diversified shapes make the photovoltaic module not only a power generation device, but also an artistic expression or design element. In addition, photovoltaic modules of different geometric shapes can be customized according to the specific conditions of the installation position (such as orientation, inclination angle, etc.) to ensure the maximum light receiving area and efficiency, thereby helping to improve the power generation capacity, especially in environments with limited space or complex lighting conditions.

[0044] On the basis of the above structure, the profiled flexible photovoltaic module structure further comprises a junction box 12, a double-stranded cable 13, and a DC waterproof male head 14. The junction box 12 is mounted on the back or side of the profiled flexible photovoltaic module. The junction box 12 contains electrical elements such as fuses, diodes, etc. for connecting the output terminals of the photovoltaic cells, which can protect the circuit and prevent reverse current. The junction box 12 also provides a convenient operating interface, so that the installer can easily connect or disconnect the power line and perform necessary debugging or maintenance work. One end of the double-stranded cable 13 is connected to the corresponding terminal in the junction box 12, and the other end is connected to other devices or systems through the DC waterproof male head 14. The DC waterproof male head 14 serves as the connection interface between the photovoltaic module and the external system, allowing the external system to quickly connect to the packaged photovoltaic module.

[0045] In another example embodiment, the fixing structure includes at least one.

[0046] In actual application, the specific number of fixing structures can be set according to the characteristics of the installation surface (such as flatness, material, shape, etc.) and specific installation requirements (such as wind load, seismic load, etc. environmental factors). For example, on larger photovoltaic modules, or when the installation surface is irregular or in harsh environments, multiple fixing structures can be configured to distribute the load and provide more reliable fixing effect.

[0047] The present application allows the designer to adjust the specific number of fixing structures according to actual needs, thereby ensuring that the profiled flexible photovoltaic module 1 can be safely and stably installed and worked under various conditions.

[0048] In another example embodiment, the fixing structure includes a first fixing member 4 and a second fixing member 5, and the first fixing member 4 and the second fixing member 5 are inserted.

[0049] In this embodiment, the first fixing member 4 and the second fixing member 5 are connected by insertion, allowing the operator to adjust the position of the profiled flexible photovoltaic module 1 during installation according to actual needs. For example, if it is found that the position of the photovoltaic module needs to be fine-tuned during installation, the first fixing member 4 can be slid forward and backward in the second fixing member 5 to achieve this without the need to reposition the entire fixing structure, thereby greatly simplifying the installation process. In addition, for a non-planar or curved installation surface, the use of an insertion method allows the first fixing member 4 and the second fixing member 5 to slide along the contour of the installation surface, thereby better fitting the installation surface and ensuring the flatness and stability of the photovoltaic module after installation. Furthermore, the use of an insertion method also allows the distance between the first fixing member 4 and the second fixing member 5 to be adjustable, so that even after the photovoltaic module is installed, the tension or installation angle of the photovoltaic module can be adjusted according to actual conditions to optimize its performance.

[0050] In summary, the first fixing member 4 and the second fixing member 5 are connected by using an insertion method, which not only improves the convenience of photovoltaic module installation and use, but also enhances the ability of the photovoltaic module to cope with complex environments.

[0051] In another exemplary embodiment, as shown in Figure 6 The first fixing member 4 includes a first base 4-1, a first pressing block 4-2, and a first fixing plate 4-3. The first base 4-1 is connected to the first pressing block 4-2 in a mating manner, and a first gap is formed between the first base 4-1 and the first pressing block 4-2, with one side edge of the profiled flexible photovoltaic module 1 being clamped in the first gap. The first base 4-1 and the first fixing plate 4-3 are integrally formed, with the first fixing plate 4-3 being located at the bottom of the profiled flexible photovoltaic module 1 and extending from one side edge of the profiled flexible photovoltaic module 1 to a middle position thereof.

[0052] In this embodiment, the first base 4-1 and the first pressing block 4-2 are designed to have a specific shape and size to achieve a close fit, which can ensure that one side edge of the profiled flexible photovoltaic module 1 is clamped securely in the first gap formed by the two, preventing displacement or loosening of the profiled flexible photovoltaic module 1 after installation. In addition, the first fixing plate 4-3 extends from one side edge of the profiled flexible photovoltaic module 1 to a middle position thereof, which helps to evenly distribute external forces applied to a larger area, thereby enhancing the stability of the fixing and to some extent acting as a support to prevent the profiled flexible photovoltaic module 1 from deforming due to external forces.

[0053] In another exemplary embodiment, as shown in Figure 7As shown, the first base 4-1 comprises a first groove 4-1-1, a second groove 4-1-2 and a first connecting platform 4-1-5, wherein the first groove 4-1-1 and the second groove 4-1-2 are integrally connected with the first fixing plate 4-3 through the first connecting platform 4-1-5, a first baffle 4-1-4 is arranged at the connection between the first groove 4-1-1 and the second groove 4-1-2, a second baffle 4-1-3 is arranged at the side of the second groove 4-1-2 away from the first groove 4-1-1, a first mounting hole 4-1-7 is arranged at the middle of the first groove 4-1-1, and first bolt holes 4-1-6 are symmetrically arranged at both sides of the first mounting hole 4-1-7.

[0054] In this embodiment, the first base 4-1 is designed with double grooves, which can provide positioning space for the first pressing block 4-2, and can ensure close cooperation between the first pressing block 4-2 and the first base 4-1 during installation, and can also ensure that the edge of the special-shaped flexible photovoltaic module 1 can be stably clamped in the first gap formed by the two, so as to ensure that it can remain stable in various environments (such as strong wind and other bad weather).

[0055] In another exemplary embodiment, continuing to refer to Figure 7 , the first pressing block 4-2 is in a stepped shape and comprises a first pressing cover 4-2-1 and a second pressing cover 4-2-2 which are integrally formed, wherein the first pressing cover 4-2-1 is located in the first groove 4-1-1 and matches the first groove 4-1-1, a first pressing piece 4-2-4 is arranged at the connection between the first pressing cover 4-2-1 and the second pressing cover 4-2-2, the first pressing piece 4-2-4 is located in the first groove 4-1-1 and closely adheres to the first connecting platform 4-1-5, a second pressing piece 4-2-3 is arranged at the side of the first pressing cover 4-2-1 away from the second pressing cover 4-2-2, the second pressing piece 4-2-3 is located in the second groove 4-1-2 and closely adheres to the second groove 4-1-2, a first through hole 4-2-6 is arranged at the middle of the first pressing cover 4-2-1, first screw holes 4-2-5 are symmetrically arranged at both sides of the first through hole 4-2-6, the first through hole 4-2-6 is correspondingly arranged with the first mounting hole 4-1-7, and the first screw holes 4-2-5 are symmetrically arranged with the first bolt holes 4-1-6.

[0056] In this embodiment, the first pressing block 4-2 is in the shape of a step, which can make the first pressing block 4-2 perfectly match the first groove 4-1-1 and the second groove 4-1-2 on the first base 4-1, ensuring the accuracy and stability of the installation of the special-shaped flexible photovoltaic module 1. In addition, the first pressing piece 4-2-4 is arranged at the connection between the first pressing cover 4-2-1 and the second pressing cover 4-2-2, and the pressing piece is located in the first groove 4-1-1 and tightly attached to the first connecting platform 4-1-5; while the second pressing piece 4-2-3 is arranged on the side of the first pressing cover 4-2-1 away from the second pressing cover 4-2-2, and the pressing piece is located in the second groove 4-1-2 and tightly contacts with the second groove 4-1-2. The segmented pressing piece can increase the contact area and provide better clamping force, while ensuring that the first pressing block 4-2 can exert sufficient pressure on the special-shaped flexible photovoltaic module 1 without damaging it, so as to firmly fix the edges of the module and keep it stable even under external forces (such as wind load).

[0057] In summary, the special structure of the first pressing block 4-2 helps to evenly disperse the pressure from above, reduces the risk of local stress concentration, and thus improves the durability and reliability of the first fixing part 4.

[0058] Next, the installation process of the first base 4-1 and the first pressing block 4-2 will be briefly described. First, the first through hole 4-2-6 of the first pressing cover 4-2-1 is aligned with the first mounting hole 4-1-7 of the first base 4-1, then the first machine screw 6 is inserted into the first mounting hole 4-1-7 through the first through hole 4-2-6 (as shown in Figure 15 The first machine screw 6 is then tightened using a wrench or other tool, so that the head of the first machine screw 6 tightly fits on the first pressing cover 4-2-1, and the threaded part of the first machine screw 6 extends into the first mounting hole 4-1-7 and engages with it. This process not only realizes physical connection, but also ensures that the first pressing block 4-2 will not easily loosen or shift through friction and mechanical locking.

[0059] In another exemplary embodiment, as Figure 8As shown, the second fixing member 5 comprises a second base 5-1, a second pressing block 5-2 and a second fixing plate 5-3, wherein the second base 5-1 is connected with the second pressing block 5-2 in a matching mode, and a second gap is formed between the second base 5-1 and the second pressing block 5-2, and the other side edge of the profiled flexible photovoltaic module 1 is clamped in the second gap; the second base 5-1 is integrally formed with the second fixing plate 5-3, the second fixing plate 5-3 is located at the bottom of the profiled flexible photovoltaic module 1 and extends from the other side edge of the profiled flexible photovoltaic module 1 to the position of the first fixing plate 4-3, and the second fixing plate 5-3 is provided with a slot 5-4, and the first fixing plate 4-3 is inserted into the second fixing plate 5-3 through the slot 5-4.

[0060] In this embodiment, the slot 5-4 provided in the second fixing plate 5-3 can provide an accurate insertion path for the first fixing plate 4-3, so as to ensure that the first fixing member 4 can be smoothly connected with the second fixing member 5. This design can avoid the problem of inaccurate positioning caused by the traditional fixing mode, thereby improving the installation accuracy of the fixing structure. In addition, the design of the slot 5-4 can make the same fixing structure adapt to photovoltaic modules of different sizes or shapes, thereby reducing the need for customizing special fixing structures for specific specifications of products, and thus reducing the production cost and improving the market competitiveness of the products.

[0061] In another example embodiment, as shown in Figure 9 As shown, the second base 5-1 comprises a third groove 5-1-1, a fourth groove 5-1-2 and a second connecting table 5-1-5, wherein the third groove 5-1-1 and the fourth groove 5-1-2 are integrally connected with the second fixing plate 5-3 through the second connecting table 5-1-5, a third blocking piece 5-1-4 is arranged at the connection between the third groove 5-1-1 and the fourth groove 5-1-2, a fourth blocking piece 5-1-3 is arranged on the side of the fourth groove 5-1-2 away from the third groove 5-1-1, a second mounting hole 5-1-7 is arranged at the middle part of the third groove 5-1-1, and second bolt holes 5-1-6 are symmetrically arranged on both sides of the second mounting hole 5-1-7.

[0062] In this embodiment, the second base 5-1 has the same structure as the first base 4-1, and thus the second base 5-1 has the same functions and technical effects as the first base 4-1, which will not be described here.

[0063] In another example embodiment, continuing to refer to Figure 9The second pressing block 5-2 is also stepped, comprising a third pressing cover 5-2-1 and a fourth pressing cover 5-2-2 which are integrally formed. The third pressing cover 5-2-1 is located in the third groove 5-1-1 and matches the third groove 5-1-1. The third pressing cover 5-2-1 is provided with a third pressing piece 5-2-4 at the connection with the fourth pressing cover 5-2-2. The third pressing piece 5-2-4 is located in the third groove 5-1-1 and closely matches the second connecting platform 5-1-5. The third pressing cover 5-2-1 is provided with a fourth pressing piece 5-2-3 on the side away from the fourth pressing cover 5-2-2. The fourth pressing piece 5-2-3 is located in the fourth groove 5-1-2 and closely matches the fourth groove 5-1-2. The third pressing cover 5-2-1 is provided with a second through hole 5-2-6 in the middle. The second through hole 5-2-6 is provided with a second screw hole 5-2-5 symmetrically on both sides. The second through hole 5-2-6 corresponds to the second mounting hole 5-1-7, and the second screw hole 5-2-5 corresponds to the second bolt hole 5-1-6.

[0064] In this embodiment, the second pressing block 5-2 has the same structure as the first pressing block 4-2, so it has the same functions and technical effects as the first pressing block 4-2, which will not be repeated here. In addition, the second pressing block 5-2 is also mounted on the second base 5-1 by machine screws (using the second machine screw 7, as shown in Figure 16

[0065] In another exemplary embodiment, as shown in Figure 10 Figure 11 Figure 12 The bottom of the first fixed plate 4-3 is provided with a plurality of fastening nuts 4-4 which are arranged along the extension direction of the first fixed plate 4-3. The bottom of the second fixed plate 5-3 is provided with a sliding groove 5-5. The plurality of fastening nuts 4-4 slide in the sliding groove 5-5 when the first fixed plate 4-3 and the second fixed plate 5-3 are inserted.

[0066] ​​​In this embodiment, the fastening nut 4-4 is threadedly engaged with the bolt or screw, and can firmly secure the matched first fixing plate 4-3 to the second fixing plate 5-3. After the first fixing plate 4-3 is inserted into the slot 5-4 of the second fixing plate 5-3, the operator can slide the fastening nut 4-4 to the appropriate position in the sliding groove 5-5, and lock the fastening nut 4-4 in the sliding groove 5-5 by tightening, so that the fastening nut 4-4 and the sliding groove 5-5 form a firm locking structure, thereby achieving the fixed connection of the first fixing plate 4-3 and the second fixing plate 5-3 (as shown in Figure 13 and Figure 14 This locking mechanism can ensure that the profiled flexible photovoltaic module 1 will not easily move or fall off even under the action of wind load or other external force. In addition, since the fastening nut 4-4 can slide in the sliding groove 5-5, first, the position of the photovoltaic module can be fine-tuned during installation, so that the operator can adjust the optimal installation position of the module according to the actual situation on site, without the need to disassemble or reposition the entire photovoltaic module, thereby improving the installation efficiency of the photovoltaic module; second, through the sliding fastening method, the same fixing structure can be applied to photovoltaic modules of different sizes or shapes, thereby increasing the versatility of the fixing structure and reducing the need to customize special fixing structures for photovoltaic modules of different specifications; third, when the photovoltaic module needs to be disassembled or reinstalled, the operator only needs to loosen the fastening nut 4-4, and then easily pull out the first fixing plate 4-3 from the slot 5-4 to achieve the separation of the first fixing plate 4-3 and the second fixing plate 5-3, thereby simplifying the maintenance work. Fourth, if a component is damaged (such as the first pressing block 4-2 or the second pressing block 5-2), the damaged part can be replaced individually without replacing the entire fixing device.

[0067] In another exemplary embodiment, the first connecting platform 4-1-5 and the second connecting platform 5-1-5 both adopt a hollow structure.

[0068] In this embodiment, by setting the first connecting table 4-1-5 and the second connecting table 5-1-5 as a hollow structure, first, the weight of the entire photovoltaic module can be reduced, making it easier to fix on different installation surfaces. Second, the hollow structure provides additional space for fasteners such as bolts, allowing more flexible adjustment of the position or angle of the photovoltaic module during installation. This helps to achieve the best light receiving angle, improve power generation efficiency, and better fit on uneven surfaces, ensuring the flatness and aesthetics after installation. Third, the hollow structure can make the first base 4-1 and the second base 5-1 better adapt to uneven installation surfaces, adjust the height consistency of the base through the internal space, and ensure that the photovoltaic module can be stably and firmly installed on any installation surface.
