[0036] As known from the background art, during the use of photovoltaic modules, there is a risk that the frame body and the corner brackets may be separated, thereby causing the stability of the photovoltaic modules to decrease.

[0037] A photovoltaic module provided in one embodiment of the present application includes a frame body and a corner bracket. The frame body includes a bottom edge, a first side edge, a load-bearing portion, and a second side edge, which are sequentially connected to form a corner bracket cavity. The corner bracket includes two connecting portions connected in an L-shape, each connecting portion having a first sub-connecting plate and a second sub-connecting plate that are parallel to each other, with a gap groove formed between the first sub-connecting plate and the second sub-connecting plate. One of the first sub-connecting plate or the second sub-connecting plate of the corner bracket is disposed within the corner bracket cavity, and the other of the first sub-connecting plate or the second sub-connecting plate is disposed outside the corner bracket cavity. In this manner, a surface of the first side edge facing the corner bracket cavity and a surface of the second side edge facing the corner bracket cavity can both generate friction with the connecting portions of the corner bracket. Furthermore, when the first side edge is located within the gap groove, a surface of the first side edge facing away from the second side edge can generate friction with the first sub-connecting plate. Alternatively, when the second side edge is located within the gap groove, a surface of the second side edge facing away from the first side edge can generate friction with the second sub-connecting plate. That is to say, when the corner bracket is assembled into the corner bracket cavity, there are at least three contact surfaces between the corner bracket and the frame body that can generate friction. Compared with the case where the connecting portion is entirely disposed in the corner bracket cavity, at least one contact surface is added between the corner bracket and the frame body, which is beneficial to improving the assembly stability of the corner bracket and the frame body. During the use of the photovoltaic module, the first sub-connecting plate or the second sub-connecting plate located in the corner bracket cavity may have dimensional deviation problems due to wear, thereby reducing the installation stability of the first sub-connecting plate or the second sub-connecting plate in the corner bracket cavity. However, since the gap groove of the corner bracket restricts the movement of the first side portion or the second side portion, the gap groove can compensate for the dimensional deviation of the first sub-connecting plate or the second sub-connecting plate, stabilize the relative position of the corner bracket and the frame body, and thus avoid the problem of the corner bracket and the frame body directly falling off, thereby improving the use stability of the photovoltaic module.

In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0039] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists, A and B exist at the same time, and B exists. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0041] In the description of the embodiments of the present application, the orientations or positional relationships indicated by technical terms such as "length", "width", "thickness", "up", "down", "horizontal", "vertical", "top", "bottom", "inside" and "outside" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0042] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense.

[0048] refer to Figure 1The photovoltaic module includes a frame body 100, which includes a bearing portion 103, a first side portion 101, a second side portion 102 and a bottom portion 104. The bearing portion 103 and the bottom portion 104 are both arranged in a horizontal direction and the bearing portion 103 is located above the bottom portion 104. The first side portion 101 and the second side portion 102 are both arranged in a vertical direction and the first side portion 101 and the second side portion 102 are both located between the bearing portion 103 and the bottom portion 104. The bottom portion 104, the first side portion 101, the bearing portion 103 and the second side portion 102 are sequentially connected to enclose a corner code cavity 105. Figure 2 and Figure 3 The photovoltaic module further includes: an angle bracket 200, which includes two L-shaped connecting parts 201, each of which has a first sub-connecting plate 211 and a second sub-connecting plate 221 parallel to each other, and a gap groove 202 is formed between the first sub-connecting plate 211 and the second sub-connecting plate 221. Figure 4 In (a), the first sub-connecting plate 211 can be located in the corner code cavity 105, and the second side portion 102 is located in the gap groove 202, and the second sub-connecting plate 221 is located on the side of the second side portion 102 away from the first side portion 101; or, referring to Figure 4 In (b), the second sub-connecting plate 221 is located in the corner code cavity 105, and the first side portion 101 is located in the gap groove 202, and the first sub-connecting plate 211 is located on a side of the first side portion 101 away from the second side portion 102.

[0049] The photovoltaic assembly provided in the embodiment of the present application includes a frame body 100 and a corner code 200. The bottom edge 104, the first side edge 101, the bearing portion 103 and the second side edge 102 of the frame body 100 are connected in sequence to form a corner code cavity 105. The corner code 200 includes two connecting portions 201 connected in an L shape. Each connecting portion 201 has a first sub-connecting plate 211 and a second sub-connecting plate 221 parallel to each other, and a gap groove 202 is formed between the first sub-connecting plate 211 and the second sub-connecting plate 221. One of the first sub-connecting plate 211 or the second sub-connecting plate 221 of the angle bracket 200 is disposed in the angle bracket cavity 105, and the other of the first sub-connecting plate 211 or the second sub-connecting plate 221 is disposed outside the angle bracket cavity 105. In this way, the surface of the first side portion 101 facing the angle bracket cavity 105 and the surface of the second side portion 102 facing the angle bracket cavity 105 can both generate friction with the connecting portion 201 of the angle bracket 200. In addition, referring to Figure 4 (a) in the embodiment, when the first side portion 101 is located in the gap groove 202, the surface of the first side portion 101 away from the second side portion 102 can generate friction between the first sub-connection plate 211, or, referring to Figure 4In (b), when the second side portion 102 is located within the gap groove 202, the surface of the second side portion 102 away from the first side portion 101 can generate friction with the second sub-connecting plate 221. In other words, when the corner bracket 200 is assembled into the corner bracket cavity 105, there are at least three contact surfaces between the corner bracket 200 and the frame body 100 that can generate friction. Compared to the case where the connecting portion 201 is entirely disposed within the corner bracket cavity 105, there is at least one additional contact surface between the corner bracket 200 and the frame body 100, which helps improve the assembly stability of the corner bracket 200 and the frame body 100. During the use of the photovoltaic module, the first sub-connecting plate 211 or the second sub-connecting plate 221 located in the corner code cavity 105 may have dimensional deviation problems due to wear, which may lead to a decrease in the installation stability of the first sub-connecting plate 211 or the second sub-connecting plate 221 in the corner code cavity 105. However, since the gap groove 202 of the corner code 200 will restrict the movement of the first side portion 101 or the second side portion 102, the gap groove 202 can compensate for the dimensional deviation of the first sub-connecting plate 211 or the second sub-connecting plate 221, stabilize the relative position of the corner code 200 and the frame body 100, and avoid the problem of direct detachment of the corner code 200 and the frame body 100, thereby helping to improve the stability of the use of the photovoltaic module.

[0050] In some embodiments, the width of the gap groove 202 may be less than or equal to the thickness of the first side portion 101. Figure 4 In (b), when the second sub-connecting plate 221 is located in the corner code cavity 105, the first side portion 101 can be located exactly in the gap groove 202, and the gap groove 202 can generate a clamping force on the first side portion 101, so as to improve the assembly stability of the frame body 100 and the corner code 200, thereby improving the use stability of the photovoltaic module.

[0051] In some embodiments, the width of the gap groove 202 may be less than or equal to the thickness of the second side portion 102. Figure 4 In (a), when the first sub-connecting plate 211 is located in the corner code cavity 105, the second side portion 102 can be located exactly in the gap groove 202, and the gap groove 202 can generate a supporting force on the second side portion 102, so as to improve the assembly stability of the frame body 100 and the corner code 200, thereby improving the use stability of the photovoltaic module.

[0052] Figure 5 This is a schematic diagram of a partially enlarged structure of a gap groove provided in one embodiment of the present application.

[0053] In some embodiments, reference Figure 5The surfaces of the first sub-connecting plate 211 and / or the second sub-connecting plate 221 facing the gap groove 202 may have a snap-fit structure 203. Thus, when the first side portion 101 is disposed in the gap groove 202, the friction between the first side portion 101 and the first sub-connecting plate 211 and / or the second sub-connecting plate 221 may be increased, thereby facilitating improved assembly stability between the frame body 100 and the corner bracket 200, and thereby facilitating improved operational stability of the photovoltaic module. Alternatively, when the second side portion 102 is disposed in the gap groove 202, the friction between the second side portion 102 and the first sub-connecting plate 211 or the second sub-connecting plate 221 may be increased, thereby facilitating improved assembly stability between the frame body 100 and the corner bracket 200, and thereby facilitating improved operational stability of the photovoltaic module.

[0054] For example, the clamping structure 203 may be Figure 5 The multiple serrated structures shown are arranged in sequence, or the snap-fit structures are multiple protruding structures of other shapes.

[0055] exist Figure 5 In the example, the surfaces of the first sub-connecting plate 211 and the second sub-connecting plate 221 facing the gap groove 202 are both provided with the snap-fit structure 203. In some embodiments, the snap-fit structure 203 may be provided only on the surface of the first sub-connecting plate 211 facing the gap groove 202, or only on the surface of the second sub-connecting plate 221 facing the gap groove 202.

[0056] In some embodiments, when the first sub-connecting plate is disposed within the corner bracket cavity, the surface of the first sub-connecting plate facing away from the second sub-connecting plate may also have a snap-fit structure. This can increase friction between the first sub-connecting plate and the inner wall of the corner bracket cavity, thereby improving the assembly stability between the frame body and the corner bracket, and further improving the operational stability of the photovoltaic module.

[0057] In some embodiments, when the second sub-connecting plate is disposed within the corner bracket cavity, the surface of the second sub-connecting plate facing away from the first sub-connecting plate may also have a snap-fit structure. This can increase friction between the second sub-connecting plate and the inner wall of the corner bracket cavity, thereby improving the assembly stability between the frame body and the corner bracket, and further improving the operational stability of the photovoltaic module.

[0058] Figure 6 A schematic cross-sectional view along the horizontal direction of a corner bracket and a frame body when assembled according to one embodiment of the present application is shown.

[0059] In some embodiments, the first sub-connecting plate 211 may have a first through-hole 311, the second sub-connecting plate 221 may have a second through-hole 312, the first side portion 101 may have a first mounting hole 301, the second side portion 102 may have a second mounting hole 302, and the first through-hole 311, the second through-hole 312, the first mounting hole 301, and the second mounting hole 302 may interpenetrate. In this manner, bolts may be sequentially inserted through the first mounting hole 301, the first through-hole 311, the second mounting hole 302, and the second through-hole 312 to secure the corner bracket to the frame body, thereby improving the assembly stability of the corner bracket and the frame body and thereby facilitating the service life of the photovoltaic module.

[0060] exist Figure 6 In the example, the first sub-connecting plate 211 is disposed in the corner bracket cavity 105, and the second side portion 102 is disposed in the clearance groove. Thus, the first mounting hole 301, the first through-hole 311, the second mounting hole 302, and the second through-hole 312 are sequentially connected. In some embodiments, when the second connecting plate is disposed in the corner bracket cavity and the first side portion is disposed in the clearance groove, the first through-hole, the first mounting hole, the second through-hole, and the second mounting hole are sequentially connected.

[0062] In some embodiments, reference Figure 7 When the first sub-connecting plate 211 is disposed within the corner bracket cavity 105 and the second side portion 102 is disposed within the clearance groove, the first sub-connecting plate 211 may have a first blind hole 313, the second sub-connecting plate 221 may have a second through hole 312, and the second side portion 102 may have a second mounting hole 302. The second through hole 312, the second mounting hole 302, and the first blind hole 313 are sequentially connected, and the inner walls of the second through hole 312, the second mounting hole 302, and the first blind hole 313 are all threaded. In this way, a bolt matching the threaded connection can be sequentially inserted through the second through hole 312, the second mounting hole 302, and the first blind hole 313 to secure the corner bracket 200 to the frame body 100.

[0063] In some embodiments, when the second sub-connecting plate is disposed within the angle bracket cavity and the first side portion is disposed within the clearance groove, the second sub-connecting plate may have a second blind hole, the first sub-connecting plate may have a first through hole, and the first side portion may have a first mounting hole. The first through hole, the first mounting hole, and the second blind hole are sequentially connected, and the inner walls of the first through hole, the first mounting hole, and the second blind hole are all threaded. In this manner, a bolt matching the threaded portion can be sequentially passed through the first through hole, the first mounting hole, and the second blind hole to secure the angle bracket to the frame body.

[0064] In some embodiments, a connection portion of the corner code can be connected to the corresponding frame body by Figure 6 Install in the manner shown, the other connecting part of the corner bracket can be connected to the corresponding frame body by Figure 7 Install as shown.

[0065] Figure 8 This is a schematic structural diagram of a second frame body provided in an embodiment of the present application.

[0066] In some embodiments, reference Figure 8 The connection point between the first side portion 101 and the supporting portion 103 is the first connection point, the connection point between the second side portion 102 and the supporting portion 103 is the second connection point, and the distance between the end of the supporting portion 103 relative to the second side portion 102 away from the first side portion 101 and the first connection point is greater than the distance between the second connection point and the first connection point; the connection point between the first side portion 101 and the bottom portion 104 is the third connection point, the connection point between the second side portion 102 and the bottom portion 104 is the fourth connection point, and the distance between the end of the bottom portion 104 relative to the second side portion 102 away from the first side portion 101 and the third connection point is greater than the distance between the fourth connection point and the third connection point.

[0067] That is, the end of the supporting portion 103, relative to the second side portion 102, away from the first side portion 101, protrudes from a side surface of the second side portion 102 away from the first side portion 101, and the bottom portion 104, relative to the end of the second side portion 102, away from the first side portion 101, protrudes from a side surface of the second side portion 102 away from the first side portion 101. Thus, when the first sub-connecting plate 211 is located within the corner bracket cavity 105 and the second side portion 102 is located within the gap groove 202, the second sub-connecting plate 221 is located on the side of the second side portion 102 away from the first side portion 101, and the upper and lower ends of the second sub-connecting plate 221 are clamped between the supporting portion 103 and the bottom portion 104. This further stabilizes the relative position between the corner bracket 200 and the frame body 100, thereby improving the assembly stability of the photovoltaic module and, therefore, the operational stability of the photovoltaic module.

[0068] In some embodiments, when the end of the supporting portion relative to the second side away from the first side protrudes from a surface on a side of the second side away from the first side, the end of the supporting portion relative to the second side away from the first side can also bend toward the bottom portion. In this way, when the first sub-connecting plate is located within the corner bracket cavity and the second sub-connecting plate is located on the side of the second side away from the first side, the second sub-connecting plate can be easily engaged between the supporting portion and the bottom portion, further improving the assembly stability of the corner bracket and the frame body.

[0069] It should be noted that in Figure 8 In the example, the width of the bottom edge portion 104 is greater than the width of the supporting portion 103. Such a wider width of the bottom edge portion 104 can help improve the horizontal stability of the frame body 100 and prevent the frame body 100 from tipping over. In some embodiments, the width of the bottom edge portion can be equal to the width of the supporting portion.

[0070] Figure 9 This is a schematic structural diagram of a third frame body provided in an embodiment of the present application.

[0071] In some embodiments, reference Figure 9 The bottom edge portion 104 is bent toward the bearing portion 103 relative to the end of the first side portion 101 away from the second side portion 102 to form a first bent portion 114; the bearing portion 103 is bent toward the bottom edge portion 104 relative to the end of the first side portion 101 away from the second side portion 102 to form a second bent portion 113; the first bent portion 114, the first side portion 101 and the second bent portion 113 form a limiting groove 110.

[0072] In this way, when the second sub-connecting plate 221 is located in the corner code cavity 105 and the first side portion 101 is located in the gap groove 202, the first sub-connecting plate 211 is located on the side of the first side portion 101 away from the second side portion 102, and the first sub-connecting plate 211 can be engaged in the limiting groove 110, so as to facilitate stabilizing the relative position of the corner code and the frame body, improving the assembly stability of the photovoltaic module, and thereby improving the use stability of the photovoltaic module.

[0073] In some embodiments, the depth of the limiting groove 110 in a direction perpendicular to the surface of the first side portion 101 is less than or equal to the thickness of the first sub-connecting plate 211 , which facilitates the first sub-connecting plate 211 to be engaged in the limiting groove 110 .

[0074] In some embodiments, when the frame body 100 has a limiting groove 110, the first sub-connecting plate 211 can also be installed in the corner code cavity 105, and the second side portion 102 is located in the gap groove 202, and the second sub-connecting plate 221 is located on the side of the second side portion 102 away from the first side portion 101.

[0075] It should be noted that in Figure 9 For example, the bottom edge 104 protrudes from the side surface of the second side 102 away from the first side 101 relative to the end of the second side 102 away from the first side 101. In this way, the width of the bottom edge 104 is relatively wide, which can help improve the horizontal stability of the frame body 100 and prevent the frame body 100 from tipping over. In some embodiments, the end of the bottom edge relative to the second side away from the first side can be flush with the surface of the second side away from the first side.

[0076] Figure 10 This is a structural diagram of the assembly of two fixing components and a third frame body provided in an embodiment of the present application.

[0077] In some embodiments, reference Figure 10 The photovoltaic assembly may further include: a fixing component 300, the fixing component 300 including a first fixing portion 310, a second fixing portion 320 and a third fixing portion 330 connected in sequence, the first fixing portion 310 being located in the limiting groove 110; Figure 10 (b) in the figure, the third fixing portion 330 may be located on the bottom surface of the bottom edge portion 104, or, referring to Figure 10 In (a), the third fixing portion 330 can be located on the side of the bottom portion 104 away from the second side portion 102 relative to the first side portion 101, and the bottom surface of the third fixing portion 330 is flush with the bottom surface of the bottom portion 104; one end of the second fixing portion 320 is connected to the side of the first fixing portion 310 away from the first side portion 101, and the other end of the second fixing portion 320 is connected to the third fixing portion 330.

[0078] In this way, the frame body 100 can be fixed to the bracket through the fixing component 300. Since the first fixing portion 310 is engaged in the limiting groove 110, the fixing component 300 and the frame body 100 can be fixed in relative position without other components such as bolts.

[0079] In some embodiments, the first fixing portion may have a first fixing hole, and the first side portion may have a first positioning hole, wherein the first fixing hole and the first positioning hole are interconnected. In this manner, the fixing component and the frame body may be secured by bolts passing through the first fixing hole and the first positioning hole, thereby further improving the assembly stability of the fixing component and the frame body and enhancing the operational stability of the photovoltaic module.

[0080] In some embodiments, the third fixing portion may have a third fixing hole for mounting the fixing component to the bracket. In some embodiments, when the third fixing portion is located on the bottom surface of the bottom edge portion, the bottom edge portion may have a bottom positioning hole that interpenetrates with the third fixing hole. In this manner, the frame body and the fixing component may be simultaneously secured to the bracket using bolts passing through the bottom positioning hole and the third fixing hole.

[0081] In some embodiments, in a direction perpendicular to the side of the first side portion 101 , the thickness of the first fixing portion 310 is less than or equal to the depth of the limiting groove 110 , which facilitates the first fixing portion 310 to be engaged in the limiting groove 110 .

[0082] In some embodiments, when the first sub-connecting plate 211 is located in the corner code cavity 105 and the second side portion 102 is located in the gap groove 202, the second sub-connecting plate 221 is located on the side of the second side portion 102 away from the first side portion 101, and the limiting groove 110 can be used only to place the first fixing portion 310.

[0083] In some embodiments, when the second sub-connecting plate 221 is located in the corner code cavity 105 and the first sub-connecting plate 211 is located in the limiting groove 110, the first fixing portion 310 and the first sub-connecting plate 211 can be located at different positions in the length direction of the frame body 100, that is, the first fixing portion 310 and the first sub-connecting plate 211 are located at different positions in the limiting groove 110, so that the limiting groove 110 can be used to fix the first fixing portion 310 and also to fix the first sub-connecting plate 211.

[0084] In some embodiments, when the second sub-connecting plate 221 is located in the angle code cavity 105 and the first sub-connecting plate 211 is located in the limiting groove 110, the first fixing portion 310 and the first sub-connecting plate 211 can both be located at the same position in the limiting groove 110, that is, the first fixing portion 310 can be located on the side of the first sub-connecting plate 211 away from the first side portion 101, so that the first fixing portion 310 and the first sub-connecting plate 211 can be stacked in the limiting groove 110, and the limiting groove 110 can simultaneously engage the first fixing portion 310 and the first sub-connecting plate 211.

[0085] In some embodiments, in a direction perpendicular to the side of the first side portion 101, the sum of the thicknesses of the first fixing portion 310 and the first sub-connecting plate 211 can be less than or equal to the depth of the limiting groove 110, so as to facilitate the limiting groove 110 to simultaneously engage the first fixing portion 310 and the first sub-connecting plate 211.

[0086] In some embodiments, the first fixing portion may have a first fixing hole, the first sub-connecting plate may have a first through hole, the second sub-connecting plate may have a second through hole, the first side portion may have a first mounting hole, the second side portion may have a second mounting hole, and the first fixing hole, the first through hole, the second through hole, the first mounting hole, and the second mounting hole may interpenetrate each other. Thus, when the first fixing portion and the first sub-connecting plate are stacked and disposed within the retaining groove, bolts may be sequentially inserted through the first fixing hole, the first through hole, the first mounting hole, the second through hole, and the second mounting hole, thereby achieving mutual fixation of the frame body, the corner bracket, and the fixing component.

[0087] In some embodiments, reference Figure 1 The photovoltaic assembly may further include: a photovoltaic laminate 400 , which is located on the top surface of the bearing portion 103 of the frame body 100 , and the bearing portion 103 is located on a side of the photovoltaic laminate 400 facing away from sunlight.

[0088] In some embodiments, the photovoltaic laminate 400 may include: a solar cell; an adhesive film covering a surface of the solar cell; and a cover plate covering a surface of the adhesive film away from the solar cell.

[0089] In some embodiments, the cell may be any one of a PERC cell (Passivated Emitter and Rear Cell), a PERT cell (Passivated Emitter and Rear Totally-diffused cell), a TOPCon cell (Tunnel Oxide Passivated Contact), a HIT / HJT cell (Heterojunction Technology), or a BC cell (Back Contact). In some embodiments, the cell may be a monocrystalline silicon solar cell, a polycrystalline silicon solar cell, an amorphous silicon solar cell, or a multi-compound solar cell. The multi-compound solar cell may specifically be a cadmium sulfide solar cell, a gallium arsenide solar cell, a copper indium selenide solar cell, or a perovskite solar cell.

[0090] In some embodiments, the material of the film may be an organic encapsulation film such as ethylene vinyl acetate (EVA) film, polyethylene octene elastomer (POE) film or polyvinyl butyral (PVB) film.

[0091] In some embodiments, the cover plate can be a glass cover plate, a plastic cover plate or the like with light-transmitting function. In some embodiments, the surface of the cover plate facing the film can be a concave-convex surface, thereby increasing the utilization rate of the incident light. Figure 1 as well as Figures 8 to 10 The frame body 100 may further include a limiting portion 106, which is located above the supporting portion 103, the bottom of the limiting portion 106 is connected to the supporting portion 103, and the top of the limiting portion 106 is bent toward the supporting portion 103 to form a slot 107 with the supporting portion 103, and the slot 107 is used to place the photovoltaic laminate 400.

[0092] Figure 11 This is a schematic structural diagram of a fourth frame body provided in an embodiment of the present application.

[0093] In some embodiments, the connection point between the limiting portion 106 and the supporting portion 103 is the end of the supporting portion 103 away from the second side portion 102 relative to the first side portion 101, and the positive projection of the top of the limiting portion 106 close to one end of the supporting portion 103 on the surface of the supporting portion 103 coincides with the connection point between the first side portion 101 and the supporting portion 103. That is to say, in the vertical direction, the top of the limiting portion 106 is flush with the first side portion 101 near one end of the supporting portion 103. In this way, when the photovoltaic laminate 400 is placed in the slot 107, the limiting portion 106 can exert sufficient downward pressure and fixation on the photovoltaic laminate 400, thereby avoiding the problem of misalignment or falling off of the photovoltaic laminate 400. At the same time, the width of the top of the limiting portion 106 after bending is small, which can avoid the top of the limiting portion 106 from blocking the surface of the photovoltaic laminate 400, thereby avoiding the reduction of the light-receiving area of the photovoltaic laminate 400, which is beneficial to maintaining the photovoltaic module with good light absorption efficiency and improving the light conversion rate of the photovoltaic module.

[0094] The installation process of the photovoltaic module is as follows: the laminate 400 is inserted into the slot 107 from the side of the frame body 100 at an angle. After the edge of the laminate 400 is inserted into the slot 107, structural adhesive is injected into the slot 107 to achieve bonding and fixation of the laminate 400 and the frame body 100; after the structural adhesive is cured, the photovoltaic module is trimmed and the overflowed structural adhesive is cleaned out. After that, the photovoltaic module can be packed, stored and transported; when the photovoltaic module needs to be put into use, the frame body 100 is fixed to the bracket or the pressure blocks and / or purlins on the roof, so that the frame body is 100 times fixed to the target object.

[0095] In some embodiments, as Figure 11 As shown, the inner wall of the card slot 107 facing the photovoltaic laminate 400 may have multiple glue overflow grooves, which can be used to accommodate part of the structural glue to prevent the structural glue from covering the surface of the photovoltaic laminate 400 and blocking the light, thereby improving the light absorption efficiency of the photovoltaic module.

[0096] exist Figure 1 and Figures 8 to 11 In the example, the connection point between the limiting portion 106 and the supporting portion 103 is taken as the end of the supporting portion 103 relative to the first side portion 101 away from the second side portion 102 . Figure 12 A schematic structural diagram of a fifth frame body provided in an embodiment of the present application; Figure 13 This is a schematic diagram of the assembly structure of a fixing component and a fifth frame body provided in one embodiment of the present application.

[0097] In some embodiments, reference Figure 12, the connection point between the limiting portion 106 and the supporting portion 103 can be closer to the second side portion 102 than the connection point between the first side portion 101 and the supporting portion 103. In this way, the end of the supporting portion 103 relative to the first side portion 101 away from the second side portion 102 can form a corner with the limiting portion 106, referring to Figure 13 When a fixing component 300 is set on the side of the first side portion 101 away from the second side portion 102, the surface of the fixing component 300 facing the frame body 100 can be designed according to the shape of the first side portion 101 and the limiting portion 106, which is conducive to improving the stability of the fixing component 300 in fixing the frame body 100 on the bracket. It can be understood that compared with the case where the limiting portion 106 is aligned with the first side portion 101, a corner is formed between the end of the bearing portion 103 relative to the first side portion 101 away from the second side portion 102 and the limiting portion 106, which can limit the relative displacement between the frame body 100 and the fixing component 300, increase the load of the fixing component 300 on the frame body 100, and thus improve the strength and stability of the photovoltaic module.

[0098] exist Figure 12 and Figure 13 In the embodiment, taking the bottom edge portion 104 as an example, the end portion of the bottom edge portion 104 relative to the first side edge portion 101 away from the second side edge portion 102 is bent toward the direction of the bearing portion 103 to form the first bending portion 114. This can further increase the load between the fixing component 300 and the frame body 100, which is beneficial to improving the fixing strength of the fixing component 300 to the frame body 100, and improving the strength and stability of the photovoltaic module.

[0099] Figure 14 A schematic structural diagram of a sixth frame body provided in an embodiment of the present application; Figure 15 This is a schematic diagram of the assembly structure of a fixing component and a sixth frame body provided in one embodiment of the present application.

[0100] In some embodiments, reference Figure 14 When the connection point between the limiting portion 106 and the supporting portion 103 is closer to the second side portion 102 than the connection point between the first side portion 101 and the supporting portion 103, the end of the supporting portion 103 away from the second side portion 102 relative to the first side portion 101 can also be bent in a direction away from the bottom portion 104 to form a third bent portion 133. In this way, the limiting portion 106 and the third bent portion 133 can form a groove structure, referring to Figure 15When a fixing component 300 is set on the side of the first side portion 101 away from the second side portion 102, the surface of the fixing component 300 facing the frame body 100 can be designed according to the shape of the first side portion 101 and the limiting portion 106, so that the third bending portion 133 is engaged with the fixing component 300, which is beneficial to improve the assembly stability of the fixing component 300 and the frame body 100, thereby improving the overall use stability of the photovoltaic module.

[0101] exist Figure 14 and Figure 15 In the embodiment, taking the end of the bottom edge portion 104 relative to the first side edge portion 101 away from the second side edge portion 102 as an example, the end protrudes from the surface of the first side edge portion 101 away from the second side edge portion 102, in this way, the load between the fixing component 300 and the frame body 100 can be further increased, which is beneficial to improving the fixing strength of the fixing component 300 to the frame body 100, and improving the strength and stability of the photovoltaic module.

[0102] Figure 16 A schematic structural diagram of a seventh frame body provided in an embodiment of the present application; Figure 17 This is a schematic diagram of the assembly structure of two fixing components and a seventh frame body provided in an embodiment of the present application.

[0103] In some embodiments, reference Figure 16 When the first bending portion 114, the first side portion 101 and the second bending portion 113 of the frame body 100 form the limiting groove 110, the connection point between the limiting portion 106 and the supporting portion 103 can be set flush with the connection point between the first side portion 101 and the supporting portion 103. In this way, the limiting portion 106 and the second bending portion 113 form a corner, referring to Figure 17 When the frame body 100 is assembled with the fixing component 300, the shape of the second fixing portion 320 can be designed according to the corner shape formed by the limiting portion 106 and the second bending portion 113, thereby increasing the load between the fixing component 300 and the frame body 100, and increasing the fixing strength of the fixing component 300 to the frame body 100, thereby improving the strength and stability of the photovoltaic module.

[0104] In some embodiments, when the first bending portion, the first side portion and the second bending portion of the frame body form a limiting groove, the connection point between the limiting portion and the supporting portion can also be arranged closer to the second side portion than the connection point between the first side portion and the supporting portion.

[0105] Figure 18 Provided for an embodiment of this application Figure 9 A partial enlarged structural diagram of the frame body is shown.

[0106] In some embodiments, in conjunction with reference Figure 1 、 Figure 9and Figure 18 The surface of the supporting portion 103 facing the photovoltaic laminate 400 includes a first surface 123 and a second surface 133. In the thickness direction relative to the photovoltaic laminate 400, the first surface 123 and the second surface 133 both extend obliquely away from the photovoltaic laminate 400, and the second surface 133 is located on the side of the edge of the first surface 123 away from the photovoltaic laminate 400; the angle between the oblique direction of the first surface 123 and the thickness direction of the photovoltaic laminate 400 is α1, and the angle between the oblique direction of the second surface 133 and the thickness direction of the photovoltaic laminate 400 is α2, and α1<α2.

[0107] By arranging the first surface 123 in a direction away from the photovoltaic laminate 400 relative to the thickness direction of the photovoltaic laminate 400, it is advantageous to facilitate the tilted insertion of the photovoltaic laminate 400 into the slot 107 during the installation process of the laminate 400 and the frame body 100. Compared with inserting the laminate 400 into the slot 107 horizontally, the appropriate tilt angle can reduce the difficulty of inserting the photovoltaic laminate 400 into the slot 107, thereby improving the installation efficiency and yield of the photovoltaic laminate 400 and the frame body 100. At the same time, during the insertion process of the photovoltaic laminate 400, the risk of damage to the edge of the photovoltaic laminate 400 can be avoided, thereby improving the yield of the photovoltaic module. The tilt angle of the second surface 133 is greater than the tilt angle of the first surface 123, so that the second surface 133 can guide the photovoltaic laminate 400, thereby further reducing the difficulty of inserting the photovoltaic laminate 400. At the same time, the processing difficulty of the first surface 123 and the second surface 133 is reduced, which is conducive to reducing the processing cost of the frame body 100.

[0108] In some embodiments, the angle α1 between the inclination direction of the first surface 123 and the thickness direction of the photovoltaic laminate 400 satisfies: 90°<α1≤100°, for example, α1 can be 91°, 91.5°, 92°, 92.5°, 93°, 93.5°, 94°, 94.5°, 95°, 95.5°, 96°, 96.5°, 97°, 97.5°, 98°, 98.5°, 99°, 99.5° or 100°, etc.

[0109] In some embodiments, α1 and α2 satisfy: 10°≤α2-α1≤20°, for example, α2-α1 can be 10°, 10.5°, 11°, 1.59°, 12.5°, 13°, 13.5°, 14°, 14.5°, 15°, 15.5°, 16°, 16.5°, 17°, 17.5°, 189°, 18.5°, 19°, 19.5° or 20°, etc.

[0110] If the difference between α2 and α1 is small, for example, α2-α1 is less than 10°, the second surface 133 has a poor guiding effect on the photovoltaic laminate 400. If the difference between α2 and α1 is large, for example, α2-α1 is greater than 20°, the volume of structural adhesive required to be filled between the second surface 133 and the photovoltaic laminate 400 is large, which increases the material cost of fixing the frame body 100 and the laminate 400, prolongs the time required for the structural adhesive to cure, and increases the risk of the structural adhesive in the slot 107 flowing out of the slot 107, thereby reducing the bonding strength between the photovoltaic laminate 400 and the supporting portion 103. Therefore, setting 10°≤α2-α1≤20° can improve the guiding effect of the second surface 133 on the photovoltaic laminate 400, reduce the material cost of fixing the frame body 100 and the photovoltaic laminate 400, and reduce the risk of the structural adhesive flowing out of the slot 107, thereby improving the bonding strength between the supporting portion 103 and the photovoltaic laminate 400.

[0111] The photovoltaic assembly provided in the embodiment of the present application includes a frame body 100 and a corner code 200. The bottom edge 104, the first side edge 101, the bearing portion 103 and the second side edge 102 of the frame body 100 are connected in sequence to form a corner code cavity 105. The corner code 200 includes two connecting portions 201 connected in an L shape. Each connecting portion 201 has a first sub-connecting plate 211 and a second sub-connecting plate 221 parallel to each other, and a gap groove 202 is formed between the first sub-connecting plate 211 and the second sub-connecting plate 221. One of the first sub-connecting plate 211 or the second sub-connecting plate 221 of the angle bracket 200 is disposed in the angle bracket cavity 105, and the other of the first sub-connecting plate 211 or the second sub-connecting plate 221 is disposed outside the angle bracket cavity 105. In this way, the surface of the first side portion 101 facing the angle bracket cavity 105 and the surface of the second side portion 102 facing the angle bracket cavity 105 can both generate friction with the connecting portion 201 of the angle bracket 200. In addition, referring to Figure 4 In (a), when the first side portion 101 is located in the gap groove 202, the surface of the first side portion 101 away from the second side portion 102 can generate friction between the first sub-connection plate 211, or, Figure 4In (b), when the second side portion 102 is located within the gap groove 202, the surface of the second side portion 102 away from the first side portion 101 can generate friction with the second sub-connecting plate 221. In other words, when the corner bracket 200 is assembled into the corner bracket cavity 105, there are at least three contact surfaces between the corner bracket 200 and the frame body 100 that can generate friction. Compared to the case where the connecting portion 201 is entirely disposed within the corner bracket cavity 105, there is at least one additional contact surface between the corner bracket 200 and the frame body 100, which helps improve the assembly stability of the corner bracket 200 and the frame body 100. During the use of the photovoltaic module, the first sub-connecting plate 211 or the second sub-connecting plate 221 located in the corner code cavity 105 may have dimensional deviation problems due to wear, which may lead to a decrease in the installation stability of the first sub-connecting plate 211 or the second sub-connecting plate 221 in the corner code cavity 105. However, since the gap groove 202 of the corner code 200 will restrict the movement of the first side portion 101 or the second side portion 102, the gap groove 202 can compensate for the dimensional deviation of the first sub-connecting plate 211 or the second sub-connecting plate 221, stabilize the relative position of the corner code 200 and the frame body 100, and avoid the problem of direct detachment of the corner code 200 and the frame body 100, thereby helping to improve the stability of the use of the photovoltaic module.

[0112] Those skilled in the art will appreciate that the above-described embodiments are specific examples for implementing the present application, and that in actual applications, various changes in form and detail may be made thereto without departing from the spirit and scope of the present application. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined in the claims.
