[0037] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1 and Figure 2 Description of a frame 100 for a photovoltaic module 200 according to an embodiment of the present invention.

[0038] like Figure 1 and Figure 2 As shown, the frame 100 for a photovoltaic module 200 according to the first aspect embodiment of the present invention includes a main body portion 1 and an extension portion 2.

[0039] Specifically, an installation space 11 is formed on the main body 1, and the photovoltaic body 201 of the photovoltaic module 200 is adapted to be installed in the installation space 11. The extension portion 2 and the main body 1 are aligned along a first direction (i.e., along...). Figure 1 The direction indicated by the middle arrow A) is connected to the side away from the installation space 11, and the first direction is the width direction of the frame 100 (that is, Figure 1 (Left and right directions in the middle).

[0040] For example, when the frame 100 is used for the photovoltaic module 200, the assembly process of the frame 100 and the photovoltaic body 201 is roughly as follows: First, adhesive is injected into the mounting space 11. Then, the photovoltaic body 201 is moved, and one edge of the photovoltaic body 201 is installed in the mounting space 11. This arrangement provides the mounting space 11 with an accurate mounting position for the photovoltaic body 201 and fixes the photovoltaic module 200, preventing displacement or shaking during transportation, installation, and use, and protecting the photovoltaic cells 2012 from mechanical damage. It should be noted that the examples in this application all use the short side of the photovoltaic body 201 installed in the mounting space 11 of the frame 100 as an example. When the long side of the photovoltaic body 201 is installed in the mounting space 11 of the frame 100 (not shown in the figure), the installation method is similar to the short side installation, thereby ensuring the stability of the photovoltaic body 201 installation.

[0041] For example, in Figure 1 and Figure 3 In the example, the extension portion 2 is located on the left side of the main body portion 1. Compared with a conventional frame, the frame 100 is lengthened in the first direction by adding the extension portion 2. When the frame 100 and the photovoltaic module 200 are assembled and installed on the photovoltaic sound barrier 300, the frame 100 fits within the receiving space 3011 of the fixing structure 301 of the photovoltaic sound barrier 300. Due to the increased length of the frame 100 in the first direction, only a portion of the main body portion 1 and the installation space 11 are partially enclosed by the upper part of the fixing structure 301. Therefore, the photovoltaic cell 2012 is not blocked by the fixing structure 301, and the photovoltaic cell 2012 is less prone to hot spots, thereby improving the power generation of the photovoltaic module 200 and extending the service life of the photovoltaic cell 2012.

[0042] Furthermore, the extension portion 2 further increases the structural strength of the frame 100 and improves its stability. When the photovoltaic module 200 is installed outdoors, encountering rain, snow, or sandstorms, the external load on the photovoltaic module 200 increases. The presence of the extension portion 2 can increase the load-bearing capacity of the photovoltaic module 200, preventing the photovoltaic module 200 from being affected by a sudden increase in load due to external environmental factors, thus effectively improving the safety and service life of the photovoltaic module 200. In addition, the frame 100 has a simple structure, is easy to process and form, and is easy to install, effectively reducing the production and installation costs of the frame 100.

[0043] According to this utility model, the frame 100 for a photovoltaic module 200 has a simple structure, is easy to process and form, easy to install, and convenient to use, effectively reducing the production and installation costs of the frame 100. By adding an extension 2 connected to the main body, when the frame 100 and the photovoltaic module 200 are assembled and installed on the photovoltaic sound barrier 300, the surface of the photovoltaic main body 201 is less likely to be blocked by the upper part of the mounting parts of the photovoltaic sound barrier 300, such as the fixing structure 301, and hot spots are less likely to form on the photovoltaic main body 201, thereby further improving the power generation of the photovoltaic module 200 and enhancing its performance. In addition, the structural strength of the frame 100 is further increased, improving its structural stability and preventing the photovoltaic module 200 from being affected by sudden increases in load caused by external environmental factors, effectively improving the safety and service life of the photovoltaic module 200.

[0044] According to some embodiments of this utility model, refer to Figure 1 The length of the extension 2 along the first direction is L, where L satisfies: 10mm≤L≤50mm.

[0045] When the length L of the epitaxial portion 2 along the first direction is less than 10mm, the length L is too short. The portion of the photovoltaic body 201 near the installation space 11 is easily blocked by the upper part of the fixing structure 301, which may cause local light spots and uneven current in the series circuit of the solar cells during long-term use, potentially reducing the photoelectric conversion efficiency of the photovoltaic module 200. When the length L of the epitaxial portion 2 along the first direction is greater than 50mm, the length L is too long. The overall width of the photovoltaic module 200 increases, requiring more space for the frame 100, which will affect the transportation and installation costs of the photovoltaic module 200. Moreover, the excessive length L of the epitaxial portion 2 along the first direction increases the amount of material used in the production of the frame 100, raising the production cost of the frame 100.

[0046] Therefore, by setting the length L of the extension portion 2 along the first direction to satisfy 10mm≤L≤50mm, the length L of the extension portion 2 along the first direction is reasonably set. When the frame 100 and the photovoltaic body 201 are assembled and installed in the receiving space 3011, the upper part of the fixing structure 301 no longer obstructs the surface of the photovoltaic body 201, thereby improving the photoelectric conversion efficiency of the photovoltaic module 200, enhancing its performance and safety, and further extending its service life. Furthermore, while ensuring the installation and performance of the photovoltaic body 201, flexible installation of the photovoltaic module 200 can be achieved, and the production cost of the frame 100 can be effectively controlled.

[0047] According to some embodiments of this utility model, refer to Figures 1-3 The extension portion 2 and the main body portion 1 together define a first cavity 3. The first cavity 3 and the mounting space 11 are arranged along a first direction. The first cavity 3 penetrates the extension portion 2 along a second direction (i.e., along...). Figure 5 The two end faces (in the direction indicated by the middle arrow B) are perpendicular to the first direction.

[0048] Combination Figure 1 A portion of the left side of the main body 1 is connected to the right side of the extension 2 to jointly define the first cavity 3. The mounting space 11 is located on the right side of the first cavity 3 along a first direction, and the first cavity 3 is in a through-hole state along a second direction. Therefore, the design of the first cavity 3 effectively reduces the amount of raw materials used in molding the frame 100, lowering the production cost of the frame 100. Furthermore, it reduces the weight of the frame 100, thereby reducing the overall weight of the photovoltaic module 200, facilitating the installation and transportation of the frame 100 and the photovoltaic module 200, and expanding the application scenarios of the photovoltaic module 200.

[0049] Additionally, refer to Figure 3The first cavity 3 also facilitates further fixation of the photovoltaic module 200 during installation. For example, after the frame 100 is connected to the photovoltaic body 201 to assemble the photovoltaic module 200, when the photovoltaic module 200 is placed in the receiving space 3011 of the fixing structure 301 of the photovoltaic sound barrier 300, the fixing component, such as a steel wire, can pass through the first cavity 3, thereby achieving further installation and fixation of the photovoltaic module 200, or the photovoltaic module 200 can be connected to other components through the steel wire. Moreover, there is no need to make large holes or process other parts of the photovoltaic body 201 or the module, so as to reduce secondary damage to the photovoltaic module 200 during installation. In addition, the operation of fixing the photovoltaic module 200 with steel wire does not require on-site processing, maintaining the original shape of the photovoltaic module 200, reducing its installation cost and shortening the installation period, which is conducive to the rapid commissioning of the photovoltaic module 200. It should be noted that the shape and volume of the first cavity 3 can be set according to the actual situation, such as the volume of the photovoltaic module 200, the installation scenario, etc., and are not specifically limited here.

[0050] According to some embodiments of this utility model, refer to Figure 1 The first cavity 3 is provided with at least one reinforcing structure 31, which divides the first cavity 3 into multiple sub-cavities 32. The term "at least one" refers to the presence of at least one reinforcing structure 31 within the first cavity 3, and may also include multiple reinforcing structures 31. In the description of this utility model, "multiple" means two or more.

[0051] For example, in Figure 1 In the example, a reinforcing structure 31 is provided within the first cavity 3, which uniformly divides the first cavity 3 into two sub-cavities 32 of equal area. Therefore, when the frame 100 is subjected to external forces, the force can be more evenly transmitted and distributed throughout the overall frame system of the frame 100 via the reinforcing structure 31. For example, when the photovoltaic module 200 encounters strong winds, the reinforcing structure 31 can disperse stress, preventing stress concentration in certain areas of the frame 100, thereby reducing the risk of wind load damage to the frame 100, improving the overall structural strength and load-bearing capacity of the frame 100, thus contributing to the long-term stable use of the frame 100 and enhancing the safety of the photovoltaic module 200. Furthermore, the two uniformly separated sub-cavities 32 can mutually constrain each other, limiting the deformation of the frame 100 under stress. When the frame 100 is subjected to pressure or tension, the reinforcing structure 31 can prevent excessive deformation of the frame 100, maintaining the overall shape and dimensional stability of the frame 100, thereby improving the performance of the photovoltaic module 200.

[0052] According to some embodiments of this utility model, refer to Figure 1The first cavity 3 has two first sidewalls 34 and two second sidewalls 35. One side of the main body 1 facing the extension 2 forms one of the two first sidewalls 34. The two first sidewalls 34 are spaced apart along a first direction. The two ends of the second sidewalls 35 are respectively connected to the same end of the two first sidewalls 34 along a third direction. The two second sidewalls 35 are spaced apart along a third direction, which is perpendicular to the first direction. One end of the reinforcing structure 31 is connected to one of the two first sidewalls 34, and the other end of the reinforcing structure 31 extends obliquely to the other of the two first sidewalls 34. Alternatively, one end of the reinforcing structure 31 is connected to one of the two first sidewalls 34, and the other end of the reinforcing structure 31 extends obliquely to one of the two second sidewalls 35. For example, in... Figure 1 In the example, the cross-sectional shape of the first cavity 3 is rectangular, and the inner wall of the first cavity 3 includes along... Figure 1 The first sidewall 34, which is opposite to the left and right sides, and along the Figure 1 The second sidewall 35 is shown as being opposite each other in the vertical direction. The first sidewall 34 on the right side of the first cavity 3 is on the same plane as the outer surface of the left side of the main body 1. Thus, the first cavity 3 is connected to the main body 1 and shares a plane, effectively strengthening the structural strength of the frame 100 and further reducing the material usage of the frame 100, lowering its production cost and facilitating large-scale production and application. For example, the frame can be a one-piece molded part to facilitate the processing and use of the frame 100.

[0053] like Figure 1 and Figure 2 As shown, the reinforcing structure 31 can extend obliquely upwards or downwards from right to left. For example, the reinforcing structure 31 can be configured in the following ways: First, one end of the reinforcing structure 31 is located on the left sidewall 34 of the first cavity 3, and the other end is located on the right sidewall 34 (not shown in the figure). Second, one end of the reinforcing structure 31 is located on the left sidewall 34 of the first cavity 3, and the other end is located on the lower sidewall 35 (not shown in the figure). Third, one end of the reinforcing structure 31 is located on the left sidewall 34 of the first cavity 3, and the other end is located on the upper sidewall 35 (not shown in the figure). Fourth, one end of the reinforcing structure 31 is located on the right sidewall 34 of the first cavity 3, and the other end is located on the lower sidewall 35 (not shown in the figure). Fifth, one end of the reinforcing structure 31 is located on the right sidewall 34 of the first cavity 3, and the other end is located on the upper sidewall 35 (not shown in the figure). Sixth, the reinforcing structure 31 is arranged along the diagonal of the first cavity 3, etc. But it is not limited to this.

[0054] This design, with the reinforcing structure 31 tilted within the first cavity 3, effectively improves the load-bearing capacity of the frame 100 in both directions, enabling the frame 100 to withstand greater external forces and enhancing the reliability and safety of the photovoltaic module 200. It should be noted that the tilt angle of the reinforcing structure 31 is related to the shape of the first cavity 3. For example, when the first cavity 3 is rectangular, the reinforcing structure 31 can be set at a 60° angle to the first direction, but this is not a limitation. When the first cavity 3 is square, the reinforcing structure 31 can be set at a 45° angle to the first direction, and so on. It is important to note that the tilt angle of the reinforcing structure 31 can be set according to actual conditions to maximize the strengthening effect of the reinforcing structure 31 on the structural strength of the frame 100.

[0055] According to some embodiments of this utility model, refer to Figure 2 There are multiple reinforcing structures 31, and the two ends of the multiple reinforcing structures 31 are respectively connected to multiple corners 33 of the first cavity 3, and the multiple reinforcing structures 31 intersect.

[0056] For example, in Figure 2 In the example, the intersection point of the two intersecting reinforcing structures 31 coincides with the center of the diagonal of the rectangular first cavity 3. This diagonal arrangement of the reinforcing structures 31 creates a stable support between opposite corners within the first cavity 3, effectively resisting external forces on the frame 100 and preventing deformation due to increased external loads. This improves the overall structural strength and stability of the frame 100, thereby enhancing the stability of the entire photovoltaic module 200. Furthermore, the intersecting arrangement of the reinforcing structures 31 achieves a higher level of fixation without requiring excessive material or space.

[0057] Furthermore, the reinforcing structures 31, arranged diagonally, evenly divide the first cavity 3 into four sub-cavities 32 of roughly equal area. This diagonal division can be understood as creating four opposing triangular structures within the first cavity 3. Triangles provide stability, effectively dispersing external forces, reducing deformation and torsion of the frame 100 under stress, and improving the overall load-bearing capacity of the frame 100, making it more able to withstand forces from different directions, such as wind, snow, and sediment.

[0058] According to some embodiments of this utility model, refer to Figures 1-3 The extension 2 along a third direction (e.g., Figure 1 The two sides of the main body 1 (in the direction indicated by the middle arrow C) are flush with the two sides of the main body 1 along the third direction, and the third direction is perpendicular to the first direction.

[0059] For example, combining Figures 1-3The upper surface of the extension portion 2 is flush with the upper surface of the main body portion 1, and the lower surface of the extension portion 2 is flush with the lower surface of the main body portion 1. Furthermore, the extension portion 2 and the main body portion 1 are connected to form an integrated frame 100 structure. This effectively improves the structural strength of the frame 100, making it more conducive to the long-term stable use of the frame 100. In addition, by setting the two sides of the extension portion 2 along the third direction to be flush with the two sides of the main body portion 1 along the third direction, the upper and lower surfaces of the frame 100 are planar, which facilitates the assembly of the frame 100 with the fixing structure 301 and improves the stability of the fit between the frame 100 and the fixing structure 301, thus contributing to the long-term stable use of the photovoltaic sound barrier 300. Furthermore, the regular overall shape of the frame 100 reduces the production difficulty and cost of the frame 100, and also improves the installation compatibility between the frame 100 and the reinforcing structure 31, reducing the installation difficulty and cost of the photovoltaic sound barrier 300. It should be noted that the first direction, the second direction, and the third direction are mutually perpendicular.

[0060] According to some embodiments of this utility model, refer to Figures 1-3 The main body 1 includes a first main body 12 and a second main body 13. Specifically, a second cavity 121 is formed on the first main body 12, and the second cavity 121 penetrates both end faces of the first main body 12 along the second direction. The second cavity 121 and the mounting space 11 are arranged along the third direction, and the second cavity 121 and the first cavity 13 are arranged along the first direction. The third direction, the first direction, and the second direction are orthogonal. One side of the second main body 13 is connected to one side of the first main body 12 along the third direction, and the other side of the second main body 13 extends along the third direction toward the side away from the first main body 12. The second main body 13 and the first main body 12 together define the mounting space 11. The side of the second main body 13 away from the first main body 12 is adapted for a photovoltaic cell 2012 that does not cover the photovoltaic body 201. The side of the second main body 13 along the first direction, the side of the first main body 12 along the first direction, and the extension 2 together define the first cavity 3.

[0061] Specifically, combined Figure 1A second cavity 121 is formed on the first main body 12 and extends through both end faces of the first main body 12 along the second direction. The second cavity 121 is located directly below the second main body 13 along the third direction. Furthermore, the first cavity 121 and the second cavity 121 are arranged along the first direction and share a common plane. Therefore, the provision of the second cavity 121 effectively reduces the overall weight of the frame 100, lowering the difficulty of transporting and installing the frame 100. Moreover, the second cavity 121 also reduces the amount of material used in the production of the frame 100, lowering production costs. In addition, when multiple frames 100 are connected, the second cavity 121 can be used to accommodate and fix corner brackets (not shown in the figure), facilitating the assembly of the photovoltaic module 200 and ensuring stable assembly.

[0062] For example, the extension of the second main body 13 includes the following situations: First, the second main body 13 extends upward only along a third direction to a position flush with the upper side surface of the extension portion 2 (not shown in the figure). In this case, the lower end of the second main body 13 along the third direction is connected to the upper surface of the first main body 12, and the left side surface along the first direction shares a plane with the right side surface of the extension portion 2. Second, the second main body 13 extends upward along a third direction to a position flush with the upper side surface of the extension portion 2, and then extends to the right along the first direction, so as to define the mounting space 11 together with the upper surface of the first main body 12. It should be noted that in the second extension method of the second main body 13 described above, the free end of the second main body 13 extends along the first direction to the photovoltaic cell 2012 that does not cover the photovoltaic body 201.

[0063] With this configuration, the upper surface of the first main body 12 and the side of the second main body 13 away from the extension 2 together define the installation space 11. When the photovoltaic body 201 is installed in the installation space 11, the photovoltaic cells 2012 of the photovoltaic body 201 are not covered by the second main body 13, making it less likely for hot spots to form on the photovoltaic cells 2012, thus improving the service life of the photovoltaic cells 2012 and the photoelectric conversion efficiency of the photovoltaic sound barrier 300. For example, the photovoltaic body 201 is bonded to the installation space 11. That is, when the photovoltaic body 201 is installed in the installation space 11, the photovoltaic body 201 can be bonded to the frame 100 with adhesive. In addition to the fixing force of the adhesive, the location of the second cavity 121 on the lower side of the photovoltaic body 201 (the lower part of the main body 1) also provides support for the photovoltaic body 201, so as to firmly install the photovoltaic body 201 onto the frame 100.

[0064] A photovoltaic module 200 according to a second aspect embodiment of the present invention includes a photovoltaic body 201 and a frame 100. Specifically, the frame 100 is the frame 100 for the photovoltaic module 200 according to the first aspect embodiment described above, and the edge of the photovoltaic body 201 fits into the mounting space 11 of the frame 100.

[0065] According to the embodiments of the present invention, the photovoltaic module 200, by adopting the aforementioned frame 100, improves the long-term stability of the photovoltaic module 200 and extends its service life. Furthermore, when the photovoltaic module 200 is installed on the fixing structure 301 of the photovoltaic sound barrier 300, the fixing structure 301 is less likely to obstruct the photovoltaic cells 2012, which also improves the photoelectric conversion efficiency of the photovoltaic module 200, reduces the formation of hot spots, and enhances the performance of the photovoltaic module 200.

[0066] According to a third aspect embodiment of the photovoltaic sound barrier 300 of the present utility model, referring to... Figure 3 This includes the frame 100 for the photovoltaic module 200 according to the first aspect embodiment described above, or the photovoltaic module 200 according to the second aspect embodiment described above.

[0067] According to the embodiments of the present invention, the photovoltaic sound barrier 300, by employing the aforementioned frame 100 or photovoltaic module 200, improves the stability and safety of the photovoltaic sound barrier 300 and expands its application scenarios. Furthermore, while ensuring its noise reduction effect, it also improves the photoelectric conversion efficiency of the photovoltaic sound barrier 300, reduces the likelihood of hot spots, and enhances its performance and service life.

[0068] According to some embodiments of this utility model, refer to Figure 3 The photovoltaic sound barrier 300 also includes a fixing structure 301, which includes a fixing body 3012 and an extension 3013. The extension 3013 is connected to one end of the fixing body 3012 along a third direction. The extension 3013 extends along a first direction. The extension 3013 and the fixing body 3012 together define at least one receiving space 3011. The outer extension 2 of the frame 100 is fitted into the receiving space 3011. The extension 3013 does not cover the photovoltaic cells 2012 of the photovoltaic module 200.

[0069] For example, in Figure 3In the example, the lower surface of the extension 3013 is connected to the upper end of the fixed body 3012 to define two symmetrically arranged receiving spaces 3011. Furthermore, the extension 3013 extends along a first direction. The fixed structure 301 is H-shaped and can be a steel structural component. Receiving spaces 3011 are formed on both sides of the H-shaped steel structure, which can be used with two photovoltaic modules 200 respectively. After assembly, the entire area of ​​the outer extension 2 of the frame 100, a portion of the main body 1, and a portion of the second cavity 121 can be accommodated within it, thereby providing further support and protection for the photovoltaic module 200 and preventing deformation or bending under stress during use. H-shaped steel structures are commonly used materials for the support structure of photovoltaic modules 200, providing stable support and maintaining a suitable angle and orientation for better sunlight reception.

[0070] For example, refer to Figure 3 An extension 2 is added to the frame 100, and the left side of the main body 1 is flush with the bottom wall of the receiving space 3011. Figure 3 The increased spacing in the left-right direction allows the photovoltaic cells 2012 and the extension section 3013 to be staggered along the first direction when the photovoltaic module 200 is mounted on the fixed structure 301. This ensures that the extension section 3013 does not obstruct the photovoltaic cells 2012 of the photovoltaic module 200, reducing the likelihood of hot spots forming on the photovoltaic cells 2012 and improving the lifespan of the photovoltaic cells 2012 and the photoelectric conversion efficiency of the photovoltaic sound barrier 300. Furthermore, the reinforcement structure 31 on the frame 100 enhances the overall structural strength of the frame 100 while controlling production costs, effectively ensuring the performance and lifespan of the photovoltaic sound barrier 300 and expanding its application scenarios.
