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.

[0108] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0109] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0110] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0111] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0112] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0113] See also Figures 1 to 5 As shown, an embodiment of the present application provides a frame connection assembly that can be used to assemble a laminate 30 or a flat tile 3. The frame connection assembly includes a first connection member 1000 and a second connection member 2000, and any one of the first connection member 1000 and the second connection member 2000 can be used to assemble a laminate 30 or a flat tile 3. The laminate 30 includes a cover plate, a packaging layer and a solar cell. The packaging layer is used to cover the surface of the battery string, and the cover plate is used to cover the surface of the packaging layer away from the battery string. The solar cell can be electrically connected in the form of a whole piece or multiple pieces to form a plurality of battery strings, and the plurality of battery strings are electrically connected in series and / or in parallel. Specifically, in some embodiments, the plurality of battery strings can be electrically connected by a conductive tape. The packaging layer covers the surface of the solar cell. For example, the packaging layer can be an organic packaging film such as an ethylene-vinyl acetate copolymer film, a polyethylene octene co-elastic precursor film or a polyethylene terephthalate film. The cover plate can be a cover plate with a light-transmitting function such as a glass cover plate or a plastic cover plate.

[0114] like Figure 6 and Figure 7 As shown in , the first direction F1 is the direction along the roof slope, the second direction F2 is the direction perpendicular to the roof slope, and the third direction F3 is the longitudinal direction of the first frame body 110. The first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other. Figure 6 and Figure 7 In the figure, the third direction F3 is a direction perpendicular to the paper surface. Similar directions shown in the following text can be understood with reference to this, and will not be described in detail.

[0115] For example Figure 1 In an application scenario shown, the first connecting member 1000 can be used to connect the edge of one laminate 30, and the second connecting member 2000 can be used to connect the edge of another laminate 30, and then the first connecting member 1000 and the second connecting member 2000 are connected to each other, so that the assembly between the two laminates 30 can be achieved.

[0116] Another example Figure 2 and Figure 3In an application scenario shown, the first connecting member 1000 can be used to connect the edge of a laminate 30 and the edge of a flat tile 3 at the same time, thereby realizing the assembly between the laminate 30 and the flat tile 3, and the second connecting member 2000 can also be used to connect the edge of a laminate 30 and the edge of a flat tile 3 at the same time, thereby realizing the assembly between the laminate 30 and the flat tile 3.

[0117] Through the introduction of the above two application scenarios, it can be known that the frame connection assembly of the present application can be switched in different application scenarios through the first connection member 1000 and the second connection member 2000, which can not only realize the assembly between two laminates 30, but also play an assembly role between the laminate 30 and the flat tile 3. Therefore, when installing the laminate 30 on the household tile roof, the frame connection assembly provided by the present application can meet the two installation requirements of the laminate 30, facilitate the arbitrary layout of the laminate 30 on the flat tile 3 on the roof, realize the connection between the laminate 30 and the laminate 30 in the appropriate area, and realize the connection between the laminate 30 and the flat tile 3 in other places. The same specification components meet different assembly requirements, which is not only convenient to manufacture and reduce costs, but also can improve installation efficiency, ensure installation aesthetics, and reduce roof load.

[0118] The use of the first connecting member 1000 and the second connecting member 2000 in different application scenarios is based on the specific structures of the first connecting member 1000 and the second connecting member 2000. Figure 4 As shown, in the cross section of the first connecting member 1000, it can be seen that the first connecting member 1000 includes a first fixing portion 1100 and a first docking portion 1200. The first fixing portion 1100 can be used to fix with the laminate 30. The first docking portion 1200 has a first main body channel 1200a, and the first docking portion 1200 has a first docking surface 1200b. The first docking surface 1200b is provided with a first docking protrusion 1200c. Figure 5 As shown, it can be seen from the cross-section of the second connecting member 2000 that the second connecting member 2000 includes a second fixing portion 2100 and a second docking portion 2200, the second fixing portion 2100 can be used to be fixed to the laminate 30, a second main body channel 2200a is opened inside the second docking portion 2200, and the second docking portion 2200 has a second docking surface 2200b, and a second docking protrusion 2200c is arranged on the second docking surface 2200b.

[0119] The first docking surface 1200b and the first docking protrusion 1200c of the first connecting member 1000 can be jointly constructed to form an area for adapting to the corresponding structure on the flat tile 3 or the corresponding structure on the second connecting member 2000, so that the first connecting member 1000 can be mutually engaged and docked with the corresponding structure on the flat tile 3 through the first docking surface 1200b and the first docking protrusion 1200c, or can be used to be mutually engaged and docked with the corresponding structure on the second connecting member 2000. Similarly, the second docking surface 2200b and the second docking protrusion 2200c of the second connecting member 2000 can also be jointly constructed to form an area for adapting to the corresponding structure on the flat tile 3 or the first docking surface 1200b and the first docking protrusion 1200c on the first connecting member 1000, so that the second connecting member 2000 can be mutually engaged and docked with the corresponding structure on the flat tile 3 through the first docking surface 1200b and the first docking protrusion 1200c, or used to be engaged and docked with the first docking surface 1200b and the first docking protrusion 1200c on the second connecting member 2000.

[0120] The first main body channel 1200a is provided inside the first docking part 1200, so that a structure that can be matched with the second connecting member 2000 or the flat tile 3 can be constructed through the outer surface of the first docking part 1200, thereby reducing the overall mass of the internal center hole without affecting its functionality.

[0134] The present application provides a photovoltaic assembly 1, which includes a laminate, a frame connection assembly, a frame assembly 1010, and a second frame. The laminate is rectangular, and the laminate has a first connection side and a second connection side that are arranged opposite to each other along a first direction, and a third connection side and a fourth connection side located between the first connection side and the second connection side, wherein the second connection side is a side of the laminate close to the eaves along the first direction. The frame assembly includes a first frame, a first hanger and a second hanger, and the first hanger and the second hanger are used for snap-fitting and assembling with the first frame, and the frame assembly is installed on the first connection side of the laminate. The second frame is installed on the second connection side of the laminate. The first connecting member and the second connecting member of the frame connection assembly are respectively arranged on the third connecting side and the fourth connecting side of the laminate.

[0135] Since the specific structure, functional principle and technical effect of the frame connection component provided by this application are described in detail in the previous text, they will not be repeated here. Any technical content related to the frame connection component can be referred to the previous records, and will not be repeated here.

[0136] Please refer to Figure 6 The embodiment of the present application provides a frame assembly 10 for a photovoltaic assembly 1. The frame assembly 10 includes a first frame 100, a first hanger 200 and a second hanger 300.

[0137] Combined with reference Figure 7 , Figure 7 Shows Figure 6 The schematic diagram of the structure of the first frame 100 of the frame assembly 10 is shown, and the first frame 100 includes a first frame body 110, a first clamping portion 120 and a second hanging portion 310. The first frame 100 can be an integrated structure or a split structure. The integrated structure and the split structure are relative. The integrated structure refers to a structure obtained by, for example, an integrated molding process, and the split structure refers to a structure in which multiple components are connected and fixed. In the embodiment of the present application, the first frame 100 is an integrated structure.

[0138] like Figure 6 and Figure 7 As shown in , the first direction F1 is the direction along the roof slope, the second direction F2 is the direction perpendicular to the roof slope, and the third direction F3 is the longitudinal direction of the first frame body 110. The first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other. Figure 6 and Figure 7 In the figure, the third direction F3 is a direction perpendicular to the paper surface. Similar directions shown in the following text can be understood with reference to this, and will not be described in detail.

[0139] The first frame body 110 is a component provided with a hollow cavity, which can be easily installed with other components while reducing weight. The first frame body 110 can be made of a beam structure. The first frame body 110 is generally a longitudinal member as a whole, and the first frame body 110 is the main body of the first frame 100. The first frame body 110 has a first installation side and a second installation side that are relatively arranged along the first direction F1. The first installation side and the second installation side are respectively corresponding sides of the corresponding part installed on the first frame body 110. Specifically, the first clamping portion 120 is arranged on the first installation side of the first frame body 110, and the first hanging portion 130 is arranged on the second installation side of the first frame body 110.

[0140] The first clamping portion 120 is a component for clamping the first hanging member 200. The first hanging member 200 is a component for connecting the first frame 100 with a target component. The first clamping portion 120 is provided with a clamping groove k1. Figure 8 , Figure 8 Shows Figure 6 The schematic diagram of the structure of the first hanging member 200 of the frame assembly 10 shows that the first hanging member 200 includes a second clamping portion 210, and the second clamping portion 210 is clamped and matched with the clamping groove k1 of the first clamping portion 120. That is, the first frame 100 can be connected to a target component by means of the first hanging member 200.

[0141] The first hanging part 130 is used to hang the second hanging part. The second hanging part 300 is used to connect the first frame 100 with another target part. The first hanging part 130 is provided with a first hanging groove g1. Fig. 9 , Fig. 9 Shows Figure 6 The schematic structural diagram of the second hanging component 300 of the frame assembly 10 is shown. The second hanging component 300 includes a second hanging portion 310 . The second hanging portion 310 is hung and matched with the first hanging groove g1 of the first hanging portion 130 .

[0142] By the second clamping part 210 of the first hanging part 200 being clamped and matched with the clamping groove k1 of the first clamping part 120, and the second hanging part 310 of the second hanging part 300 being clamped and matched with the first hanging groove g1 of the first hanging part 130, it is convenient to assemble the first hanging part 200 and the second hanging part 300 on the first frame 100. At the same time, with the help of the first hanging part 200 and the second hanging part 300, it is also convenient to realize the connection between the first frame 100 and the corresponding target component.

[0143] It can be understood that the first hanging piece 200 and the first frame 100 are connected in a snap-on manner, which is conducive to improving the reliability of the connection between the first hanging piece 200 and the first frame 100. The second hanging piece 300 and the second frame 20 are connected in a hanging manner, which is conducive to more convenient and quick assembly of the second hanging piece 300.

[0144] Therefore, when the frame assembly 10 provided in the embodiment of the present application is applied to the photovoltaic assembly 1, the connection between the photovoltaic assembly 1 and the corresponding target component and the connection between adjacent photovoltaic assemblies 1 are facilitated, thereby improving the installation efficiency.

[0145] In some embodiments, please refer to Figure 6 and Figure 7 The first clamping portion 120 includes a first clamping edge 121 and a second clamping edge 122 that are arranged opposite to each other along the second direction F2. The first clamping edge 121, the second clamping edge 122 and the first installation side of the first frame body 110 define a clamping groove k1.

[0146] In this way, by providing two clamping edges, not only the clamping slot k1 can be defined, but also the size and position of the clamping slot k1 can be more flexibly controlled to meet different usage requirements.

[0147] In some embodiments, please refer to Figure 6 and Figure 7 The first clamping edge 121 has a first surface m1 arranged along the second direction F2 and outside the clamping groove k1, and the second clamping edge 122 has a second surface m2 arranged along the second direction F2 and outside the clamping groove k1. The first surface m1 is flush with one side surface of the first frame body 110 along the second direction F2, and the second surface m2 is flush with the other side surface of the first frame body 110 along the second direction F2.

[0148] In this way, the engaging space of the engaging groove k1 can be increased as much as possible, thereby increasing the contact area between the second engaging portion 210 of the first hanging component 200 and the first engaging portion 120 , thereby improving the reliability of the connection between the first hanging component 200 and the first frame 100 .

[0149] In some embodiments, please refer to Figure 6 and Figure 7 The first clamping edge 121 has a first end d1 connected to the first frame body 110, and a second end d2 away from the first frame body 110. The second clamping edge 122 has a third end d3 connected to the first frame body 110, and a fourth end d4 away from the first frame body 110. The second end d2 extends toward the second clamping edge 122, and the fourth end d4 extends toward the first clamping edge 121.

[0150] For example, the extension direction of the second end d2 may be parallel to the second direction F2, and the extension direction of the fourth end d4 may also be parallel to the second direction F2. Of course, the extension direction of the second end d2 and the extension direction of the fourth end d4 may both intersect with the second direction F2. No specific limitation is made here.

[0151] In this way, by controlling the extension direction of the second end d2 of the first clip edge 121 and the extension direction of the fourth end d4 of the second clip edge 122, the second end d2 of the first clip edge 121 and the fourth end d4 of the second clip edge 122 can both define a limiting space with the first installation side of the first frame body 110, thereby further improving the reliability of the connection between the first hanger 200 and the first frame 100.

[0152] In some embodiments, please refer to Figure 6 and Figure 8 The second clamping portion 210 of the first hanging member 200 is provided with a first matching groove p1 and a second matching groove p2 along the second direction F2. The second end d2 of the first clamping edge 121 is located in the first matching groove p1, and the fourth end d4 of the second clamping edge 122 is located in the second matching groove p2.

[0153] In this way, the first matching groove p1 can limit the second end d2 of the first clamping edge 121, and the second matching groove p2 can limit the fourth section of the second clamping edge 122, further improving the reliability of the connection between the first hanger 200 and the first frame 100.

[0154] In some embodiments, please refer to Figures 6 to 8 The frame assembly 10 further includes a first connecting member 400 , and the first connecting member 400 is connected to the second clamping portion 210 and the bottom wall of the clamping groove k1 .

[0155] Exemplarily, the bottom wall of the clamping groove k1 may be formed by the first mounting side of the first frame body 110. Corresponding threaded holes may be provided on the second clamping portion 210 and the first mounting side of the first frame body 110, and the first connecting member 400 may be passed through the corresponding threaded holes and extend into the interior of the first frame body 110. The first connecting member 400 may be a screw.

[0156] Fig.10 A schematic structural diagram of a frame assembly 10 in another embodiment of the present application is shown; Fig.11 Shows Fig.10 The schematic diagram of the structure of the second hanging component 300 of the frame assembly 10 is shown; for the convenience of explanation, only the contents related to the embodiment of the present application are shown.

[0157] In some embodiments, please refer to Figures 6 to 8 The first hanging member 200 further includes an abutting portion 220a connected to the second clamping portion 210. The abutting portion 220a is a component used to cooperate with a corresponding target component (such as the flat tile 3 shown below). Fig.10 and Fig.11The first hanging member 200 further includes a third hanging portion 220b connected to the second clamping portion 210. The third hanging portion 220b is a component used to hang and cooperate with another corresponding target component (such as the second frame 20 shown later). Accordingly, a third hanging groove g3 may be provided on the third hanging portion 220b.

[0158] In this way, the abutting portion 220a or the third hanging portion 220b can be flexibly selected according to actual usage conditions to achieve different matching modes.

[0159] In some embodiments, please refer to Figure 6 and Figure 7 The first hanging portion 130 includes a first hanging edge 131, a second hanging edge 132, and a connecting edge 133 connecting the first hanging edge 131 and the second hanging edge 132. The first hanging edge 131 is connected to the second installation side of the first frame body 110. The first hanging edge 131, the second hanging edge 132, the connecting edge 133 and the second installation side define a first hanging groove g1.

[0160] The first hanging edge 131 has a first installation surface a1 located outside the first hanging groove g1 , the second hanging edge 132 has a second installation surface a2 located outside the first hanging groove g1 , and the connecting edge 133 has a first connecting surface y1 located outside the first hanging groove g1 .

[0161] The first mounting surface a1 and the second mounting surface a2 are connected by means of a first connecting surface y1 , and the first connecting surface y1 is configured as an arc surface.

[0162] This helps to increase the contact area between the second hanging component 300 and the first hanging portion 130 , thereby improving the reliability of the connection between the second hanging component 300 and the first frame 100 .

[0163] In some embodiments, please refer to Figure 6 and Figure 7 The first hanging edge 131 has a third mounting surface a3 located in the first hanging groove g1, the second hanging edge 132 has a fourth mounting surface a4 located in the first hanging groove g1, and the connecting edge 133 has a second connecting surface y2 located in the first hanging groove g1. The third mounting surface a3 and the fourth mounting surface a4 are connected by means of the second connecting surface y2, and the second connecting surface y2 is configured as an arc surface.

[0164] This is beneficial to increase the space of the first hanging groove g1, and further facilitates the second hanging portion 310 of the second hanging component 300 to be hung and matched with the first hanging groove g1.

[0165] For example, in the embodiments of the present application, Figure 6 and Figure 7As an example, the case where the first connecting surface y1 and the second connecting surface y2 of the connecting section are both arc surfaces is illustrated. In this case, the connecting section can be regarded as an arc section.

[0166] In some embodiments, please refer to Figure 6 , Figure 7 and Fig. 9 , the first frame body 110 has a bearing side and an abutting side arranged opposite to each other along the second direction F2. The bearing side of the first frame body 110 is a side for bearing the laminate of the photovoltaic assembly 1. The abutting side of the first frame body 110 is a side for abutting against the second hanger 300. Exemplarily, the bearing side of the first frame body 110 may be provided with a first mounting groove z1, and the first mounting groove z1 is used to mount the laminate.

[0167] The second hanging member 300 further includes a first supporting edge 320 connected to the second hanging portion 310. The first supporting edge 320 is located at one side of the second hanging portion 310 along the second direction F2 and abuts against the abutting side of the first frame body 110.

[0168] In this way, by providing the first supporting edge 320 , the supporting effect of the frame assembly 10 in the second direction F2 can be improved, thereby further improving the stability and reliability of the frame assembly 10 .

[0169] In some embodiments, please refer to Figure 6 , Figure 7 and Fig. 9 The second hanging member 300 further includes a second supporting edge 330 connecting the first supporting edge 320 and the second hanging portion 310. The second supporting edge 330 abuts against the side of the first hanging portion 130 away from the first hanging groove g1. The second supporting edge 330 is connected to one end of the second hanging portion 310, and is obliquely extended from the end of the second supporting edge 330 connected to the second hanging portion 310 in a direction away from the second hanging portion 310. The direction from the end of the second supporting edge 330 connected to the second hanging portion 310 points to the direction from the end of the second supporting edge 330 connected to the second hanging portion 310, and intersects with the first direction F1.

[0170] For example, the second supporting edge 330 may abut against the connecting edge 133 of the second hanging portion 310. When the first connecting surface y1 of the connecting edge 133 is configured as an arc surface, the contact area between the second supporting edge 330 and the first connecting surface y1 may be increased.

[0171] In this way, since the second supporting edge 330 is roughly inclined, when the second hanging part 310 is hung in the first hanging groove g1, the second supporting edge 330 is in contact with the second hanging part 310. The second supporting edge 330 can produce a slight deformation under the action of the installation stress, which is beneficial for the second hanging part 310 to be inserted into the first hanging groove g1, thereby improving the tightness of the connection between the second hanging part 310 and the first hanging part 130, thereby further improving the reliability of the connection between the second hanger 300 and the first frame 100.

[0172] In some embodiments, please refer to Figure 6 and Fig. 9 The first supporting edge 320 is extended along the first direction F1 , which is beneficial to increase the contact area between the first supporting edge 320 and the first frame body 110 , and further improve the supporting function of the first supporting edge 320 .

[0173] For example, Figure 6 , Figure 7 and Fig. 9 For example, the second support edge 330 is connected to one end of the second hanging portion 310, and is obliquely extended from the end of the second support edge 330 connected to the second hanging portion 310 toward a direction away from the second hanging portion 310, and the first support edge 320 is extended along the first direction F1.

[0174] In some embodiments, please refer to Figure 6 and Fig. 9 The second hanging portion 310 includes a first portion 311, a second portion 312, and a third portion 313 connecting the first portion 311 and the second portion 312. The first portion 311, the second portion 312, and the third portion 313 define a second hanging groove g2, a portion of the first hanging portion 130 is located in the second hanging groove g2, and at least a portion of the second portion 312 is located in the first hanging groove g1 and abuts against the first hanging portion 130 along the first direction F1.

[0175] For example, in conjunction with reference Figure 7 , at least a portion of the second hanging edge 132 of the first hanging portion 130 is located in the second hanging groove g2. When the connecting edge 133 of the first hanging portion 130 is configured as an arc edge, since the space of the first hanging groove g1 is increased, at least a portion of the connecting edge 133 can also be located in the second hanging groove g2.

[0176] In this way, by extending the second portion 312 into the first hanging groove g1 and partially locating the first hanging portion 130 in the second hanging groove g2, the reliability of the hanging cooperation between the first hanging portion 130 and the second hanging portion 310 is further improved.

[0177] In some embodiments, please refer to Figure 6, Figure 7 and Fig. 9 The second hanging member 300 further includes a connecting portion 340. The connecting portion 340 is connected to the side of the second hanging portion 310 away from the first frame 100, and the connecting portion 340 is used to connect the tile hanging strip. That is, the connecting portion 340 can be connected to the first portion 311 of the second hanging portion 310 and the second supporting edge 330.

[0178] In this way, by providing the connecting portion 340, it is convenient to connect the second hanging member 300 and the tile hanging strip.

[0179] In some embodiments, please refer to Figure 6 and Fig. 9 The frame assembly 10 further includes a second connecting member 500, and the connecting portion 340 is used to connect the tile hanging strips with the help of the second connecting member 500. For example, the second connecting member 500 can be a screw.

[0180] In this way, by providing the second connecting member 500, the detachable connection between the second hanging member 300 and the tile hanging strip can be easily achieved.

[0181] Of course, in some other embodiments, the second hanging member 300 and the tile hanging strip may also be connected by snapping or other fixed connection methods, which is not specifically limited here.

[0182] Fig.12 A schematic diagram of the structure of a photovoltaic module 1 in an embodiment of the present application is shown; Fig.13 A schematic structural diagram of a photovoltaic assembly 1 in another embodiment of the present application is shown; Fig.14 Shows Fig.12 and Fig.13 The schematic diagram of the structure of the second frame 20 and the laminate 30 of the photovoltaic component 1 is shown in the figure; for the convenience of explanation, only the content related to the embodiment of the present application is shown.

[0183] Based on the same inventive concept, an embodiment of the present application provides a photovoltaic assembly 1, comprising a frame assembly 10, a second frame 20 and a laminate 30 in any of the above embodiments. The laminate 30 has a first connection side and a second connection side that are relatively arranged along a first direction F1, and the second connection side is a side of the laminate 30 close to the eaves along the first direction F1. The first connection side and the second connection side of the laminate 30 are both used to install the corresponding frame. The frame assembly 10 is installed on the first connection side of the laminate 30, and the second frame 20 is installed on the second connection side of the laminate 30. The second frame 20 can be an integrated structure or a split structure.

[0184] The laminate 30 includes a cover plate, an encapsulation layer and a solar cell. The encapsulation layer is used to cover the surface of the battery string, and the cover plate is used to cover the surface of the encapsulation layer away from the battery string. The solar cell can be electrically connected in the form of a whole piece or multiple pieces to form a plurality of battery strings, and the plurality of battery strings are electrically connected in series and / or in parallel. Specifically, in some embodiments, the plurality of battery strings can be electrically connected by a conductive tape. The encapsulation layer covers the surface of the solar cell. For example, the encapsulation layer can be an organic encapsulation film such as an ethylene-vinyl acetate copolymer film, a polyethylene-octene co-elastic precursor film or a polyethylene terephthalate film. The cover plate can be a cover plate with a light-transmitting function such as a glass cover plate or a plastic cover plate.

[0185] It is understood that the photovoltaic assembly 1 can achieve corresponding installation requirements with the help of the frame assembly 10 and the second frame 20. For example, the connection between the photovoltaic assembly 1 and the tile bar, the flat tile and other photovoltaic assemblies 1 can be installed according to actual use requirements, and no specific restrictions are made here.

[0186] The advantages possessed by the frame assembly 10 in any of the above embodiments are also possessed by the photovoltaic assembly 1 and will not be described in detail here.

[0187] In some embodiments, please refer to Fig.14 The second frame 20 includes a second frame body 21 and a fourth hanging portion 22 .

[0188] The second frame body 21 is a component provided with a hollow cavity, which can be easily installed with other components while reducing weight. The second frame body 21 can be made of a beam structure. The second frame body 21 is generally a longitudinal member, and the longitudinal direction of the second frame body 21 is perpendicular to the first direction F1, and the longitudinal direction of the second frame body 21 is parallel to the longitudinal direction of the first frame body 110. The second frame body 21 is the main part of the second frame 20. The second frame body 21 has a hanging side arranged along the first direction F1. The hanging side is the corresponding side of the first frame body 110 provided with the fourth hanging portion 22.

[0189] The fourth hanging portion 22 includes a first side 22a, a second side 22b and a third side 22c connected in sequence. The first side 22a is connected to the hanging side of the second frame body 21, and the first side 22a, the second side 22b and the third side 22c define a fourth hanging groove g4. The fourth hanging groove g4 is hung and matched with the corresponding first hanging member 200.

[0190] In this way, by setting the fourth hanging part 22 to a structural form of a first side 22a, a second side 22b and a third side 22c, since the fourth hanging part 22 includes three sides, it is conducive to forming a more stable structure, thereby improving the stability of the fourth hanging part 22 during installation.

[0191] In some embodiments, please refer to Fig.14 The extending direction of the first side 22a between the hanging side of the second frame body 21 and the second side 22b, the extending direction of the second side 22b between the first side 22a and the third side 22c, and the extending direction of the third side 22c extending in a direction away from the second side 22b are all straight line directions and intersect with each other. The first direction F1, the extending direction of the first side 22a, and the extending direction of the second side 22b intersect with each other.

[0192] The extension direction of the first side 22a between the hanging side of the second frame body 21 and the second side 22b is defined as the first extension direction Y1, the extension direction of the second side 22b between the first side 22a and the third side 22c is defined as the second extension direction Y2, and the extension direction of the third side 22c extending in the direction away from the second side 22b is defined as the third extension direction Y3. That is, the first extension direction Y1, the second extension direction Y2 and the third extension direction Y3 are all straight line directions and intersect with each other. The first side 22a is extended in a straight line along the first extension direction Y1, the second side 22b is extended in a straight line along the second extension direction Y2, and the third side 22c is extended in a straight line along the third extension direction Y3. The first direction F1, the first extension direction Y1 and the second extension direction Y2 intersect with each other.

[0193] It can be understood that when the first extension direction Y1, the second extension direction Y2 and the third extension direction Y3 are all straight lines and intersect each other, the fourth hanging part 22 formed by the first side 22a, the second side 22b and the third side 22c substantially forms a triangular structure. Under such a structure, the stability of the fourth hanging part 22 is enhanced, and the deflection of the fourth hanging part 22 during the installation process is also smaller, which is conducive to the installation process.

[0194] In some embodiments, please refer to Fig.14 The second frame body 21 has a load-bearing side arranged along the second direction F2 (i.e., a side of the second frame body 21 that carries the laminate 30). The first side 22a has a first side c1 connected to the hanging side of the second frame body 21, and a second side c2 connected to the second side 22b. The first side 22a is configured to extend obliquely from the first side c1 to the second side c2 toward the load-bearing side of the second frame body 21.

[0195] In this way, the first side 22a forms a structure that is substantially inclined toward the bearing side of the second frame body 21, which is beneficial to increase the hanging space of the fourth hanging groove g4, thereby further facilitating the installation of related components.

[0196] In some embodiments, please refer to Fig.14The first side 22a extends between the first side c1 and the second side c2 in a direction that forms a preset angle α with the first direction F1. Fig.14 In order to conveniently illustrate the preset angle α, the general direction of the first direction F1 is indicated by a dotted line, and the preset angle α is represented by the angle formed between the dotted line and the first extension direction Y1. The preset angle α is 25°-60°. Exemplarily, the preset angle α can be 25°, 30°, 35°, 40°, 45°, 50°, 55°, 58° or 60°.

[0197] In this way, the mounting space of the fourth mounting groove g4 is increased while the stability of the fourth mounting portion 22 is improved, thereby facilitating the installation of related components.

[0198] In some embodiments, please refer to Fig.14 The first side 22a and the second side 22b are connected by an arc transition section (not shown in the figure).

[0199] Thus, by providing the arc transition section, it is helpful to reduce the stress generated during the installation process, thereby facilitating the installation.

[0200] In some embodiments, please refer to Fig.14 The extending direction of the second side 22b between the first side 22a and the third side 22c, the first direction F1, and the longitudinal direction of the second frame body 21 are perpendicular to each other. That is, the second extending direction Y2 is parallel to the second direction F2.

[0201] In this way, it is not only helpful to reduce the size of the second frame 20 along the first direction F1, but also enables the fourth hanging groove g4 to have a certain hanging space for easy installation.

[0202] In some embodiments, please refer to Fig.14 The extending direction of the third side 22c extending in the direction away from the second side 22b is parallel to the first direction F1. That is, the third extending direction Y3 is parallel to the first direction F1.

[0203] In this way, it is not only helpful to improve the reliability of the connection between the fourth hanging portion 22 and the relevant components, but also enables the fourth hanging groove g4 to have a certain hanging space for easy installation.

[0204] In some embodiments, please refer to Fig.14 A plurality of protrusions t are provided on a surface of the third side 22c facing the fourth hanging groove g4.

[0205] In this way, by providing the protruding portion t, it is helpful to increase the friction between the relevant components hung in the fourth hanging groove g4 and the fourth hanging portion 22, thereby improving the reliability of the hanging.

[0206] In some embodiments, please refer to Fig.14 The second frame body 21 further includes a fourth side 23 disposed on the bearing side of the second frame body 21 , and the fourth side 23 and the bearing side of the second frame body 21 define a bearing groove x, and the bearing groove x is used to bear the laminate 30. Fig.14 The laminate 30 is shown in the figure, so the position of the bearing slot x is shown in dashed lines. For example, the laminate 30 can be fixed to the slot wall of the bearing slot x by means of an adhesive layer (not shown in the figure). The top end surface of the fourth side 23 is not higher than the upper surface of the laminate 30.

[0207] Thus, since the fourth side 23 is located at the side of the laminate 30, the upper surface (i.e. Fig.14 No step structure is formed between the uppermost surface along the second direction F2 and the fourth edge 23, and dust or water accumulation will not occur at the step structure, thereby reducing cleaning costs and helping to increase the service life of the photovoltaic module 1.

[0208] In some embodiments, please refer to Fig.14 , the extension direction of the fourth side 23 extending in the direction away from the second frame body 21 is a straight line direction. That is, the fourth side 23 is arranged to extend in a straight line in the direction away from the second frame body 21. Exemplarily, the extension direction of the fourth side 23 extending in the direction away from the second frame body 21 is parallel to the second direction F2.

[0209] In this way, the fourth side 23 is facilitated to abut against the side surface of the laminate 30, which facilitates installation.

[0210] In some embodiments, please refer to Fig.14 The fourth side 23 has a first surface b facing away from the bearing groove x and an end e facing away from the second frame body 21. The first surface b includes a surface body b1 and a guide surface b2 connected between the surface body b1 and the end e of the fourth side 23.

[0211] Thus, by providing the guide surface b2, not only the lines of the fourth side 23 are made smooth, but also the rainwater can flow through easily and dust accumulation is reduced. In addition, it is also beneficial to make the fourth side 23 have a certain support strength.

[0212] In some embodiments, please refer to Fig.14 , the guide surface b2 is configured as a curved surface; or, the guide surface b2 is configured as an inclined surface. Fig.14 As an example, the case where the guide surface b2 is a curved surface is illustrated.

[0213] In this way, the shape of the guide surface b2 can be flexibly constructed as long as it is conducive to guide flow, and no specific limitation is made here.

[0214] In some embodiments, please refer to Fig.14 The second frame body 21 further includes a connecting edge 24. The first edge 22a is connected to the hanging side of the second frame body 21 by means of the connecting edge 24. The connecting edge 24 and the hanging side of the frame body define a sealing groove f, and the sealing groove f is used to install the sealing member M.

[0215] In this way, by providing the sealing groove f, it is easy to install the sealing member M, which is beneficial to water stopping and water retaining.

[0216] In some embodiments, please refer to Fig.14 The sealing member M comprises a first sealing portion M1, a second sealing portion M2 and a mounting portion M3. The first sealing portion M1 is connected between the mounting portion M3 and the second sealing portion M2. The mounting portion M3 is used for snap-fitting with the sealing groove f.

[0217] In this way, the seal M can be installed by means of the installation portion M3 through a press-type penetration installation method.

[0218] For further information, please refer to Fig.14 The second sealing portion M2 may be provided in plurality, and the plurality of second sealing portions M2 are arranged at intervals along the first direction F1F1. Fig.14 For example, a situation where three second sealing parts M2 are provided is illustrated. Of course, the number of the second sealing parts M2 can also be other numbers, which is not specifically limited here.

[0219] In this way, since a plurality of second sealing portions M2 are provided, multiple water stopping or water blocking functions can be achieved in the first direction F1 , which is beneficial to improving the waterproof performance of the photovoltaic module 1 .

After that, it is connected to the mains network to realize solar power supply.

It can be understood that for the last photovoltaic module 1b, the last photovoltaic module 1b is the first photovoltaic module 1, and the middle photovoltaic module 1c is the second photovoltaic module 1. For the middle photovoltaic module 1c, the middle photovoltaic module 1c is the first photovoltaic module 1, and the first photovoltaic module 1a is the second photovoltaic module 1.

Fig.18 As shown, the connection between the middle photovoltaic assembly 1c and the first photovoltaic assembly 1a can be understood by referring to the connection between the middle photovoltaic assembly 1c and the last photovoltaic assembly 1b illustrated above, and will not be repeated here.

[0230] Combined with reference Figure 2 , Fig.10 , Fig.11 and Fig.19 The abutting portion 220a of the first hanger 200 of the first photovoltaic component 1a abuts and cooperates with the flat tile 3.

[0231] Combined with reference Fig.14 and Fig. 20 The lower frame of the last photovoltaic module 1b is the second frame 20 illustrated in some of the above embodiments.
