[0002] Photovoltaic modules need to be equipped with photovoltaic devices such as inverters on the frame to improve the photovoltaic module's photoelectric conversion efficiency. For ease of installation, photovoltaic devices are usually installed on the B surface outside the frame. In order to ensure the connection stability of the photovoltaic device, additional connection components such as mounting plates or clamping blocks need to be added to the B surface for connection.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0027] Photovoltaic modules need to be equipped with photovoltaic devices such as inverters on the frame to improve the photovoltaic conversion efficiency of the photovoltaic modules. Figure 1 , Figure 1 It is a frame in the related art, and the frame mainly includes an A surface 31, a B surface 32, a C surface 33 and a D surface 34. The A surface 31 is the side facing the sun, the B surface 32 and the D surface 34 are vertical supporting surfaces, the B surface 32 is located on the outside of the frame, the D surface 34 is located on the inside of the frame, and the C surface 33 is located on the bottom surface of the frame.

[0028] In order to facilitate the installation of photovoltaic devices such as inverters, the photovoltaic device is usually installed on the B surface 32 outside the frame. In order to ensure the connection stability of the photovoltaic device, it is necessary to add additional connection components to the B surface 32 for connection. The additional connection components added to the B surface 32 will cause the B surface 32 to bear greater stress, resulting in stress concentration in the local area, causing cracks, defects or deformation in the frame, resulting in a reduction in the overall strength of the light frame, and significantly reducing the load performance of the frame. Therefore, the current installation method is difficult to take into account both the installation stability of the photovoltaic device and the load performance of the frame.

[0029] Based on this, in the first aspect, the embodiment of the present application provides a photovoltaic frame 100. Figure 2 and Figure 3The photovoltaic frame 100 includes a frame body 1, a supporting portion 12 and a supporting part 17. The supporting portion 12 is arranged on the frame body 1, and has a supporting surface 12a for supporting the photovoltaic device 200. The supporting portion 17 is convexly arranged on the supporting surface 12a, and is used to connect with the photovoltaic device 200. The supporting portion 12 of the photovoltaic frame 100 in the embodiment of the present application can support the photovoltaic device, and the supporting portion 17 is convexly arranged on the supporting surface and can be connected to the photovoltaic device 200, playing the role of secondary fixing the photovoltaic device 200. The supporting portion 12 cooperates with the supporting portion 17 to improve the connection stability of the photovoltaic device 200, and there is no need to add additional connecting components such as mounting plates to the photovoltaic frame 100, which reduces the stress applied to the photovoltaic frame 100, improves the structural strength of the photovoltaic frame 100, and thus can improve the load performance of the photovoltaic frame 100.

[0030] See also Figure 3 In some embodiments, the frame body 1 includes a bottom 10, a side 13, a support portion 15, a middle portion 14 and a top 11. The side 13 and the support portion 15 are spaced apart on the bottom 10; the middle portion 14 and the top 11 are spaced apart on the side 13, and the middle portion 14 is closer to the bottom 10 and connected to the support portion 15, a placement groove 16 is formed between the top 11 and the middle portion 14, and the supporting portion 12 is constructed as a structure in which the bottom 10 extends out of the supporting portion 15. As a result, the photovoltaic device 200 is arranged on the supporting portion 12 extending from the bottom 10 of the frame body 1 without destroying the structure of the side 13, so that it can maintain the vertical support function of the frame body 1, improve the structural strength of the frame body 1, and further improve the load performance of the frame body 1.

[0031] It should be noted that after the photovoltaic frame 100 is provided with the photovoltaic device 200, a plurality of photovoltaic frames 100 need to be stacked up and down for storage or transportation, and the photovoltaic frame 100 will also be installed on the photovoltaic bracket to generate electricity. The supporting portion 17 connects the photovoltaic device 200 to the supporting portion 12. In other words, the photovoltaic device 200 is located above the supporting portion 12, which can avoid interfering with the stacking and installation of the photovoltaic frame 100 by placing the photovoltaic device 200 below the supporting portion 12.

[0032] See also Figure 3 The support portion 15 is disposed between the middle portion 14 and the bottom portion 10, and is disposed opposite to the side portion 13. The side portion 13 is located outside the photovoltaic frame 100, and the support portion 15 is located inside the photovoltaic frame 100. The middle portion 14, the support portion 15, the side portion 13, and the supporting portion 12 together constitute a hollow structure of the photovoltaic frame 100, and the support portion 17 is located outside the hollow structure. The support portion 15 can cooperate with the side portion 13 to improve the vertical support effect of the photovoltaic frame 100, thereby improving the load performance of the photovoltaic frame 100.

[0033] In some embodiments, the support portion 17 is constructed as a structure formed by bending part of the support portion 12 and protruding the support surface 12a. In other words, a part of the support portion 12 itself is bent to form the support portion 17, which can be connected to the photovoltaic device 200, and the other part that is not bent plays a supporting role for the photovoltaic device 200. Therefore, the integrated bending structure design of the support portion 12 and the support portion 17 can achieve the following effects in many aspects: on the one hand, the integrated design increases the overall strength and stability of the frame body 1, reduces the failure points that may be generated due to the splicing of multiple components, and because no additional connection components are provided on the support portion 12, the load-bearing capacity of the support portion 12 is reduced, thereby reducing the stress borne by the photovoltaic frame 100, and improving the load performance of the photovoltaic frame 100. On the other hand, the support portion 12 can support the photovoltaic device 200 upward, and the support portion 17 can fix the photovoltaic device 200 from the side, thereby fixing the photovoltaic device 200 from multiple directions, improving the connection stability of the photovoltaic device 200. On the other hand, the support portion 12 is partially bent to form the support portion 17, which can better utilize the material of the original support portion 12, reduce material costs, and reduce labor waste. In other aspects, the installation process of the photovoltaic device 200 can be simplified. It only needs to be placed on the support portion 12 and connected to the support portion 17, which reduces the complexity of installation.

[0034] Optionally, the supporting portion 17 can be formed by stamping or cutting. Stamping refers to applying external force to the supporting portion 12 through a press and a mold, so that a part of the supporting portion 12 is stamped and bent relative to another part. Cutting refers to first cutting off a part of the supporting portion 12 from another part at least partially through a cutting machine, and then bending the part alone to form the supporting portion 17.

[0035] The supporting portion 12 is preferably formed by stamping, which can ensure the processing consistency of the formed supporting portion 17.

[0036] In some embodiments, an opening 121 is provided through the supporting surface 12a, and the supporting portion 17 is provided at an edge of the opening 121. Such a configuration can match the stamping forming process. Through the precise stamping and bending process, the mechanical strength and durability of the supporting portion 17 can be improved, and the photovoltaic device 200 can be reliably fixed during long-term use. At the same time, a large number of supporting portions 17 can be produced in a relatively short time, thereby improving production efficiency.

[0037] See also Figure 3 The embodiment of the present application does not limit the number of supporting parts 17 formed by the supporting portion 12, and the supporting part 17 can be one or more, such as two, three or four.

[0038] See also Figure 3The embodiment of the present application does not limit the shape of the support portion 17, and the support portion 17 may be in a square, rectangular, semicircular, trapezoidal, or other shapes. The cross-section 172 of the support portion 17 that is away from the supporting portion 12 may be an arc surface or a plane. Preferably, it is an arc surface, which enables the support portion 17 to disperse the stress on the supporting portion 12 during the formation process, reduce stress concentration, and reduce cracking of the supporting portion 12; and the arc surface has rounded corners and no sharp edges, which can reduce scratches and damage to the photovoltaic device 200 caused by impact or vibration.

[0039] See also Figure 3 , the embodiments of the present application are not limited to the formation position of the support portion 17. In some embodiments, the support portion 17 is arranged in the middle part of the supporting portion 12 and / or the supporting portion 12 is located at the edge of the outer periphery of the frame body 1. In other words, a part of the edge of the supporting portion 12 is separated and bent to form the support portion 17, and / or a part of the inner part of the supporting portion 12 is separated and bent to form the support portion 17. In the former, since the edge is exposed to the outside, one side of the support portion 17 is separated from the other part, and this method of forming the support portion 17 can reduce the processing difficulty. In the latter, the support portion 17 is formed from the inner part of the supporting portion 12, and the setting position of the support portion 17 can be adjusted to adapt to the size of the photovoltaic device 200. It can be set at any position inside the supporting portion 12, and the opening flexibility is high; and since the support portion 17 is set inside the supporting portion 12, the photovoltaic device 200 is also set close to the inner part of the supporting portion 12, increasing the supporting area of ​​the supporting portion 12 for the photovoltaic device 200 and improving the connection stability of the photovoltaic device 200.

[0040] When there are multiple support parts 17, in a first optional embodiment, some support parts 17 are formed by separating and bending a part of the edge of the supporting part 12, and other support parts 17 are formed by separating and bending a part of the inside of the supporting part 12. In a second optional embodiment, all support parts 17 are formed by separating and bending a part of the edge of the supporting part 12. In a third optional embodiment, all support parts 17 are formed by separating and bending a part of the inside of the supporting part 12. The third setting method is preferably adopted, so that each support part 17 can adjust the setting position according to the size of the photovoltaic device 200, and can improve the connection stability of the photovoltaic device 200.

[0041] In some embodiments, there are multiple support parts 17, and all of the support parts 17 are spaced apart along the length direction of the supporting portion 12 to provide fixed points for the connection of the photovoltaic device 200, which can bear the weight of the photovoltaic device 200 more evenly, disperse the load, and increase the stability of the overall structure of the photovoltaic frame 100; by adjusting the distribution intervals of the support parts 17, the supporting portion 12 can adapt to photovoltaic devices of different lengths or sizes, thereby improving the versatility of the photovoltaic frame 100.

[0042] See also Figure 3 , the embodiments of the present application are not limited to the bending direction of the support portion 17. In some embodiments, the support portion 17 includes a connection surface 171 for connecting to the photovoltaic device 200, and the connection surface 171 is parallel to or perpendicular to a side surface of the frame body 1 facing the supporting portion 12. Since the support portion 17 is formed by bending after a part of the supporting portion 12 is separated from another part, the thickness of the support portion 17 is consistent with the thickness of the supporting portion 12, and both are relatively thin. In order to improve the connection effect of the support portion 17 to the photovoltaic device 200, it is necessary to ensure that the support portion 17 and the photovoltaic device 200 have a certain connection area, and it is necessary to ensure that the support portion 17 has a certain length and width to form the connection surface 171.

[0043] See also Figure 3 When the connection surface 171 is parallel to the side surface of the frame body 1 facing the supporting portion 12, that is, the connection surface 171 faces the side portion 13, the photovoltaic device 200 can be connected to the supporting portion 17 from a direction perpendicular to the side portion 13. When the connection surface 171 is parallel to the side portion 13, since the length of the side portion 13 is longer, the length of the connection surface 171 can be increased to increase the area of ​​the connection surface 171, thereby improving the fixing effect of the photovoltaic device 200.

[0044] See also Figure 3 When the connection surface 171 is perpendicular to the side surface of the frame body 1 facing the supporting portion 12, the photovoltaic device 200 can be connected to the supporting portion 17 from a direction parallel to the side portion 13. When the connection surface 171 is perpendicular to the side portion 13, since the length of the side portion 13 is longer, it is convenient to increase the height of the connection surface 171 and thus increase the area of ​​the connection surface 171, thereby improving the fixing effect of the photovoltaic device 200.

[0045] See also Figure 3 When there are multiple support parts 17, in some optional ways, the connection surfaces 171 of some support parts 17 are parallel to the side 13, and the connection surfaces 171 of other support parts 17 are perpendicular to the side 13. In other optional ways, the connection surfaces 171 of all support parts 17 are parallel to the side 13. In other optional ways, the connection surfaces 171 of all support parts 17 are perpendicular to the side 13. The present application is not limited to the orientation of the connection surface 171 of the support part 17, and can be adaptively adjusted according to the setting position of the photovoltaic device 200.

[0046] See also Figure 2Preferably, the support portion 17 includes a plurality of support portions 17, the plurality of support portions 17 are arranged opposite to each other, the photovoltaic device 200 is located between the plurality of support portions 17, and the connection surfaces 171 of all the support portions 17 are perpendicular to the side of the frame body 1 facing the supporting portion 12. In other words, the connection surfaces 171 of all the support portions 17 face the photovoltaic device 200 and are arranged opposite to the photovoltaic device 200. Thus, the support portion 17 can be connected to the opposite side of the photovoltaic device 200, so that the photovoltaic device 200 can be clamped on the supporting portion 12, thereby improving the fixing effect of the photovoltaic device 200.

[0047] In the second aspect, the embodiment of the present application further provides a photovoltaic assembly, which includes the photovoltaic frame 100 as in the first aspect, and the photovoltaic assembly of the embodiment of the present application also has all the technical effects of the photovoltaic frame 100 described in the first aspect. The photovoltaic assembly also includes a solar cell, and the photovoltaic frame 100 is used to carry the solar cell.

[0048] See also Figure 2 In a third aspect, the present application also provides a photovoltaic system, the photovoltaic system includes a photovoltaic module and a photovoltaic device 200, the photovoltaic module includes a photovoltaic frame 100, and the photovoltaic frame 100 is the photovoltaic frame 100 of the first aspect. Figure 4 The photovoltaic device 200 includes a device body 21 and a connection structure 22 that are connected to each other, and the photovoltaic device 200 is connected to the support part 17 through the connection structure 22.

[0049] Optionally, the photovoltaic device 200 may be a micro inverter, a fast shut-off device, an optimizer, etc. Taking a micro inverter as an example, the micro inverter is electrically connected to the solar cell in the photovoltaic module. The photovoltaic module converts direct current into alternating current through an inverter for use by an AC load or for transmission to a power grid.

[0050] Optionally, the connection between the connection structure 22 and the support portion 17 may be clamped or welded, etc. Specifically, the connection structure 22 may be provided with a clamping groove, which can clamp the support portion 17. The connection structure 22 may also be directly welded to the support portion 17.

[0051] See also Figure 4, in order to improve the connection stability between the connection structure 22 and the support part 17, and to facilitate the disassembly of the photovoltaic device 200. In other embodiments, the connection structure 22 includes a hanging member 221 and a fastener 222, the hanging member 221 is connected to the device body 21 and has a through hole 223 between the hanging member 221 and the device body 21, the hanging member 221 is penetrated with a mounting hole 224, the support part 17 is located between the hanging member 221 and the device body 21, and the fastener 222 penetrates the mounting hole 224 and abuts against the support part 17 to connect the hanging member 221 with the support part 17. Since there is a through hole 223 between the hanging member 221 and the device body 21, when the fastener 222 penetrates the mounting hole 224, the support effect of the fastener 222 can be increased along the length direction of the fastener 222, thereby improving the stability of the fastener 222 abutting against the support part 17.

[0052] Optionally, the fastener 222 may be a bolt, a screw, a stud, or the like.

[0053] See also Figure 4 The structure of the hanging member 221 has the following several settings but is not limited to. In one setting, the hanging member 221 includes a first part 221a and a second part 221b connected to each other, the first part 221a is connected to the device body 21, the second part 221b is arranged relative to the device body 21 to have a through hole 223 between the device body 21, the mounting hole 224 is provided in the second part 221b, the support part 17 is located between the second part 221b and the device body 21, and the fastener 222 passes through the mounting hole 224 to press the support part 17 onto the device body 21.

[0054] See also Figure 4In another configuration, the hanging member 221 includes a first portion 221a, a second portion 221b and a third portion 221c connected to each other, one end of the first portion 221a and the third portion 221c are connected to the device body 21, and the other end extends in a direction away from the device body 21, the first portion 221a is close to the side portion 13, the third portion 221c is away from the side portion 13, the second portion 221b is arranged between the first portion 221a and the third portion 221c, the second portion 221b is arranged opposite to the device body 21 to have a through hole 223 between the second portion 221b and the device body 21, and the support portion 17 is located in a hollow portion enclosed by the first portion 221a, the second portion 221b and the third portion 221c. In this configuration, the mounting hole 224 can be arranged on the third portion 221c or the second portion 221b. When the mounting hole 224 is provided on the third part 221c, the fastener 222 moves toward the first part 221a after penetrating the mounting hole 224 from the third part 221c, and presses the support part 17 on the first part 221a, thereby fixing the photovoltaic device 200. When the mounting hole 224 is provided on the second part 221b, the fastener 222 moves toward the device body 21 after penetrating the mounting hole 224 from the second part 221b, and presses the support part 17 on the device body 21.

[0055] See also Figure 4 Preferably, in some embodiments, both ends of the hanging member 221 are connected to the device body 21, a through hole 223 is provided between the middle of the hanging member 221 and the device body 21, and a mounting hole 224 is provided in the middle of the hanging member 221. In other words, the hanging member 221 includes the first part 221a, the second part 221b and the third part 221c, and the mounting hole 224 is provided on the second part 221b. Adding the third part 221c on the basis of the first part 221a can support the fastener 222 from both sides of the fastener 222, improve the stability of the fastener 222 pressing the support part 17, and thus improve the connection effect of the photovoltaic device 200.
