TECHNICAL FIELD

[0002] The present application relates to the technical field of photovoltaic power generation, in particular to a frame suitable for a photovoltaic module, a photovoltaic module and a photovoltaic system. BACKGROUND

[0003] With the increasingly serious problem of conventional energy shortage, the continuous improvement of environmental protection and energy saving awareness, the development and utilization of renewable energy has become the energy strategy of sustainable development, and solar photovoltaic power generation is considered as the most promising new energy technology in the world. Solar photovoltaic power generation refers to a power generation system that converts solar radiation energy into electric energy directly through the photovoltaic effect of photovoltaic cells. The photovoltaic module is an important part of the solar photovoltaic power generation system.

[0004] The photovoltaic module includes a photovoltaic panel and a frame surrounding the side of the photovoltaic panel. The frame protects the side of the photovoltaic panel. However, the existing frame is usually in the shape of a "U". When the frame is applied to the photovoltaic module, the frame can only protect the side of the photovoltaic panel. When the photovoltaic panel is installed on the support frame, other components are needed to support the back of the photovoltaic panel, resulting in poor stability of the photovoltaic module and increased installation cost. TECHNICAL SOLUTION

The second object of the present application is to provide a photovoltaic module. The third object of the present application is to provide a photovoltaic system.

[0008] a main body, one side surface of the main body is a bearing surface, the bearing surface is used for supporting a back surface of a photovoltaic panel;

[0009] a first extension section extending from a side surface of the main body adjacent to the bearing surface in a direction away from the main body along the bearing surface;

[0010] a second extension section extending from an extension end of the first extension section in a direction perpendicular to the bearing surface in a direction away from the main body;

[0011] a third extension section extending from an extension end of the second extension section in a direction of the main body; the third extension section is used for abutting a front surface of the photovoltaic panel.

[0012] As a second aspect of the present application, a photovoltaic module comprises:

[0013] a photovoltaic panel;

[0015] corner connectors, adjacent to the frames are connected through the corner connectors;

[0016] connecting members, the connecting members are connected with external support structures and are connected with the corner connectors one by one.

[0017] As a third aspect of the present application, a photovoltaic system comprises a photovoltaic module as described above and a support structure, the support structure comprises:

[0018] a first support member connected with at least one of the frames and located on one side of the back surface of the photovoltaic panel, at least one end of the first support member is used for connecting with the outside

[0019] at least four second support members, one end of each of the plurality of second support members is connected to the first support member, the other end is connected to the frame respectively, and the end portions of adjacent two frames are connected with the other end of one of the second support members through the connecting members respectively. Advantages

[0020] The present application has the advantages of improving the protection effect of the frame on the photovoltaic panel, improving the stability of the photovoltaic module, reducing the installation cost, facilitating the subsequent maintenance of the photovoltaic module, and improving the stability of the connection between the photovoltaic module and the support structure.

[0021] Firstly, in the frame, one side surface of the main body is arranged as a bearing surface, a first extension section is formed from the side surface adjacent to the main body and the bearing surface and extends along the bearing surface away from the main body, the bearing surface and the first extension section support the back surface of the photovoltaic panel in the photovoltaic module, the second extension section perpendicular to the bearing surface protects the side edge of the photovoltaic panel, and the third extension section abuts the front surface of the photovoltaic panel, so that the frame realizes the packaging of the photovoltaic panel and protects the side edge of the photovoltaic panel, the bearing surface of the main body and the first extension section jointly support the back surface of the photovoltaic panel, thereby increasing the support area of the frame for the photovoltaic panel, when the frame is used in the photovoltaic module, the stability of the photovoltaic module is improved by increasing the support area of the frame for the photovoltaic panel, and the protection effect of the frame for the photovoltaic panel is improved.

[0022] Meanwhile, since the first extension section extends along the bearing surface away from the main body, and the second extension section is arranged at the extension end of the first extension section, the second extension section is used to protect the side edge of the photovoltaic panel, so that the main body is closer to the center of gravity of the photovoltaic module, the main body connects adjacent frames in the photovoltaic module, and the photovoltaic module is connected to an external support structure through the main body, thereby further improving the stability of the photovoltaic module.

[0023] Secondly, the groove is arranged on the third extension section, and the sealing element is embedded in the groove during use, so that the sealing element increases the waterproof performance between the third extension section of the frame and the front surface of the photovoltaic module, and the elasticity of the sealing element enables the third extension section to flexibly contact the front surface of the photovoltaic module, thereby avoiding damage to the photovoltaic module caused by the direct rigid contact of the third extension section to the front surface of the photovoltaic module.

[0024] Thirdly, the fourth extension section is arranged, the first extension section, the fourth extension section and the main body form a triangular structure, thereby improving the connection strength between the first extension section and the main body, avoiding the damage to the photovoltaic panel caused by the extrusion of the first extension section and the second extension section due to the possible deformation of the first extension section and the second extension section, and further improving the protection effect of the frame for the photovoltaic panel, and since the fourth extension section is arranged, especially the fourth extension section is recessed into an arc shape towards the bearing surface, the external lines of the frame are smoother, rainwater deposition is avoided, the photovoltaic module is damaged, dirt is avoided, subsequent maintenance and cleaning are facilitated, and the frame is more beautiful.

[0025] Fourth, in the photovoltaic module of the present application, the corner code is inserted into the first frame through the first insertion part, and is inserted into the second frame through the second insertion part. Then the connecting piece is connected to the corner code by using the bolt. The corner code inserted into the frame clamps the frame together with the connecting piece. The two parts cooperate with each other, which not only facilitates the connection of the adjacent frames, but also makes the connection of the adjacent frames more reliable. At the same time, since the corner code is supported in the frame, the deformation and damage of the frame are avoided, which leads to the loosening of the connection of the adjacent frames or the damage of the photovoltaic panel connected by the frame. Therefore, the installation and stability of the photovoltaic module are further improved, and the installation cost is reduced.

[0026] Fifth, in the photovoltaic system of the present application, the photovoltaic module is connected to the support structure through the frame. The first support member in the support structure is connected to the frame of the photovoltaic module. Under the action of the second support member, the connection between the frame and the first support member is strengthened, and the second support member is connected to the adjacent frame connection. The support of the support structure to the photovoltaic module is more comprehensive and balanced. When encountering external pressure, the support force to the photovoltaic module is more uniform, and the stability of the connection between the photovoltaic module and the support structure is improved.

[0027] At the same time, the adjacent frames are connected to the same second support member, which not only provides a solid support for the photovoltaic module, but also strengthens the connection between the adjacent frames, further enhances the stability of the connection between the adjacent frames, and improves the protection effect of the frame on the photovoltaic panel.

[0028] Sixth, the number of the first support members in the photovoltaic module of the present application is two or more. The plurality of first support members are evenly distributed on the back of the photovoltaic module. The plurality of first support members evenly support the photovoltaic module, further improving the stability of the connection between the photovoltaic panel and the support structure. When the number of the first support members is two or more, the photovoltaic module of the present application is also provided with a reinforcing member. The plurality of first support members are connected through the reinforcing member, so that the plurality of first support members form a whole, and the stability between the plurality of first support members is enhanced, so as to further improve the stability of the connection between the photovoltaic module and the support structure.

[0043] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the scope of protection of the present application. It can be understood that some technical means of the various embodiments described herein can be replaced or combined with each other without conflict.

[0044] In the description of the present application, if there are terms "first", "second", etc., they are only used to distinguish the described objects, and do not have any order or technical meaning. Therefore, the objects defined with "first", "second", etc. can be explicitly or implicitly included one or more objects. And "one" or "a" and the like do not represent a quantity limit, but represent the existence of at least one, and "more" represents no less than two.

[0045] In order to make the same technical features of the present application adopt the same reference signs, the reference signs of Figures 1 to 6 are adaptively adjusted.

[0046] As shown in Figures 1 to 2, referring to the priority document CN2024207424386, it is clear that in the present application, part of the photovoltaic module 100 in the corresponding priority document is expressed as a photovoltaic panel 2. The first aspect of the present embodiment discloses a frame suitable for a photovoltaic module, the photovoltaic module 100 includes a photovoltaic panel 2, which extends along the length direction and includes:

[0047] a main body 11, one side surface of the main body 11 is a bearing surface 113, the bearing surface 113 is used to support the back surface of the photovoltaic panel 2 through the back surface of the photovoltaic module 100;

[0048] a first extension section 12, which extends from the side surface of the main body 11 adjacent to the bearing surface 113 to the direction away from the main body 11 along the bearing surface 113;

[0049] a second extension section 13, which extends from the extension end of the first extension section 12 to the direction away from the main body 11 along the direction perpendicular to the bearing surface 113;

[0050] a third extension section 14, which extends from the extension end of the second extension section 13 to the direction of the main body 11; the third extension section 14 is used to abut the front surface of the photovoltaic panel 2.

[0051] It should be noted that in the present embodiment, the bearing surface 113 of the main body 11 and the first extension section 12 are used to support the back surface of the photovoltaic panel 2, the second extension section 13 is used to protect the side surface of the photovoltaic panel 2, and the third extension section 14 is used to abut the front surface of the photovoltaic panel 2, so that the frame 1 proposed in the present embodiment not only increases the support area of the back surface of the photovoltaic panel 2, but also ensures the protection of the second extension section 13 to the side surface of the photovoltaic module 100.

[0052] When the frame 1 is used in the photovoltaic module 100, a plurality of frames 1 act on different side surfaces of the photovoltaic panel 2, and the second extension section 13 is also used to define the relative position between the photovoltaic panel 2 and the frame 1 of the side surface. The distance between the third extension section 14 and the bearing surface 113 is equal to the thickness of the photovoltaic panel 2, and the third extension section 14 and the bearing surface 113 form a clamping definition of the photovoltaic panel 2.

[0053] It should be noted that in the present embodiment, the bearing surface 113 is arranged on the main body 11, which can be directly attached to the back of the photovoltaic panel 2 through the bearing surface 113 during use, and the main body 11 can also be directly connected to the external support structure (i.e. the support structure 200 in the photovoltaic system). The main body 11 should be arranged as a columnar body on the basis of meeting the function of the main body 11.

[0054] In the present embodiment, the main body 11 is preferably a polygonal prism, i.e. the cross section of the main body 11 is a polygon. As shown in FIGS. 1 and 2, the main body 11 is a quadrangular prism in the drawings of the present embodiment. In fact, the main body 11 can also be a pentagonal prism, or the main body 11 has only one flat surface, for example, the main body 11 is a semi-cylindrical body.

[0055] Further, in the present embodiment, in order to make the self-weight of the frame 1 lighter and to facilitate the connection of the two frames 1, as shown in FIGS. 1 and 2, the first through hole 112 is arranged on the main body 11 and is consistent with the length direction P.

[0056] Further, in order to make the main body 11 have higher overall strength, at least one set of reinforcing ribs 111 is arranged on the inner wall of the first through hole 112, and the reinforcing ribs 111 extend synchronously with the main body 11. It should be noted that the reinforcing ribs 111 are protrusions arranged on any inner wall of the first through hole 112, and the top end of the protrusion can either not intersect with the inner wall of the first through hole 112 or intersect with the inner wall of the first through hole 112, in which case the first through hole 112 is divided by the reinforcing ribs 111.

[0057] As shown in FIGS. 1 and 2, the side of the first extension section 12 close to the third extension section 14 is in the same plane as the bearing surface 113, which increases the area of the frame 1 attached to the back of the photovoltaic panel 2, thereby increasing the stability of the connection between the frame 1 and the photovoltaic panel 2 and the protective effect of the frame 1 on the photovoltaic panel 2, and thus increasing the stability of the photovoltaic module 100.

[0058] It should be noted that in the present embodiment, since the photovoltaic panel 2 is a multi-layer stack, in order to avoid water entering between the layers of the photovoltaic panel 2 and causing damage, as shown in FIGS. 1 and 2, the third extension section 14 is provided with a mounting groove 141 on the side close to the bearing surface 113, the mounting groove 141 is parallel to the length direction P and penetrates through the third extension section 14, and the mounting groove 141 is used to arrange a sealing member.

[0059] It should be understood that the sealing strip is usually made of a material with elasticity such as rubber, and therefore, when the frame 1 is used, the sealing member is embedded in the installation groove 141, which can not only increase the waterproof performance between the third extension section 14 of the frame 1 and the front surface of the photovoltaic panel 2 by using the sealing member, but also make the third extension section 14 and the front surface of the photovoltaic panel 2 form a flexible contact by using the elasticity of the sealing member, thereby avoiding damage to the photovoltaic panel 2 caused by the direct rigid contact of the third extension section 14 to the front surface of the photovoltaic panel 2.

[0060] In order to enhance the strength of the connection between the second extension section 13 and the first extension section 12, as shown in FIGS. 1 and 2, the frame 1 according to the present embodiment is further provided with a fourth extension section 15, which extends from the first extension section 12 in a direction opposite to the second extension section 13 towards the main body 11, and the extension end of the fourth extension section 15 is connected to the main body 11, thereby strengthening the connection between the end of the first extension section 12 and the main body 11 by using the fourth extension section 15.

[0061] Further, in the present embodiment, a triangular structure is formed between the main body 11, the first extension section 12 and the fourth extension section 15, thereby improving the connection strength between the first extension section 12 and the main body 11, i.e., by using the fourth extension section 15, damage to the photovoltaic panel 2 caused by the extrusion of the first extension section 12 and the second extension section 13 to the photovoltaic panel 2 due to the possible deformation of the first extension section 12 and the second extension section 13 is avoided, and the protection effect of the frame 1 on the photovoltaic panel 2 is further improved. In order to further improve the supporting effect of the fourth extension section 15, as shown in FIGS. 1 and 2, the extension starting section of the fourth extension section 15 is arranged at the extension end of the first extension section 12.

[0062] Further, in the present embodiment, the fourth extension section 15 is arc-shaped and recessed towards the bearing surface 113, which can make the external lines of the frame 1 more smooth and more elegant and generous.

[0063] Further, in the present embodiment, in order to reduce the weight of the frame 1, as shown in FIGS. 1 and 2, the first extension section 12, the fourth extension section 15 and the main body 11 enclose a second through hole 151, which is preferably similar to a triangle in cross section, so as to further strengthen the support of the fourth extension section 15 to the extension end of the first extension section 12.

[0074] The first plug-in part 41 is used for connecting the first frame 101, in order to facilitate the insertion of the first plug-in part 41 into the first frame 101, the end of the first plug-in part 41 is provided in a conical shape, which facilitates relative positioning, and when the conical end contacts the hole wall in the frame 1 for accommodating the first plug-in part 41, the surface of the conical end of the first plug-in part 41 can also serve as a guide.

[0075] Further, in the embodiment, in order to prevent the first plug-in part 41 from being detached from the first frame 101, the first ratchet 412 is provided on the surface of the first plug-in part 41 inserted into the first frame 101, which does not affect the insertion of the first plug-in part 41 into the first frame 101, but when the first plug-in part 41 is outward, the first ratchet 412 can play a role in preventing detachment.

[0076] It should be noted that the second plug-in part 42 and the first plug-in part 41 are the same structure, and the second plug-in part 42 is also provided with a second screw hole 421, a second ratchet 422 and a second abutting surface 423.

[0077] It should be noted that in the present embodiment, as shown in FIGS. 4-5, the photovoltaic panel 2 is rectangular, and the rectangular photovoltaic panel 2 is provided with four frames 1, including the first frame 101 and the second frame 102, and the first frame 101 and the second frame 102 have an angle at the end for easy splicing, as shown in FIG. 6, the end of the first frame 101 and the second frame 102 is 45 degrees, and when the corner code 4 is spliced, the corner code 4 is connected to the first frame 101 through the first plug-in part 41, and is connected to the second frame 102 through the second plug-in part 42, and a waterproof ring or waterproof glue layer can be provided between the first frame 101 and the second frame 102.

[0078] It should be noted that in the present embodiment, the connecting piece 3 is used to assist the corner code 4 to connect the adjacent frame 1, and is also used to connect the external support structure (i.e. the support structure 200 in the photovoltaic system), and on the basis of meeting the function of the connecting piece 3, the connecting piece 3 can be a triangular sheet directly attached to the frame 1 as shown in FIG. 6, or other shapes; the common point is that in order to cooperate with the corner code 4, the connecting piece 3 is provided with a first connecting hole 31 corresponding to the first screw hole 411, and is also provided with a second connecting hole 32 corresponding to the second screw hole 421, and when the connecting piece 3 is fixed, the bolt passes through the first connecting hole 31 and the first frame 101 to cooperate with the first screw hole 411 on the corner code 4 in the first frame 101, and the bolt passes through the second connecting hole 32 and the second frame 102 to cooperate with the second screw hole 421 on the corner code 4 in the second frame 102, so that the connecting piece 3 is connected with the corresponding corner code 4.

[0079] As shown in FIGS. 3-6, referring to the priority document CN202423189143X, in order to unify the technical feature names of the present application, the second connecting piece in the corresponding priority document is expressed as the connecting piece 3, and the photovoltaic support is expressed as the support structure 200, and the third aspect of the present embodiment discloses a photovoltaic system, comprising: the photovoltaic module 100 and the support structure 200 as described above, the support structure 200 comprises:

[0098] Firstly, in the frame 1, the side surface of the main body 11 is arranged as a bearing surface 113, and the first extension section 12 is arranged along the bearing surface 113 away from the main body 11 from the side surface adjacent to the bearing surface 113 of the main body 11.

The bearing surface 113 of the main body 11 and the first extension section 12 jointly support the back surface of the photovoltaic panel 2, thereby increasing the support area of the frame 1 to the photovoltaic panel 2. When the frame 1 is used in the photovoltaic module 100, the support area of the frame 1 to the photovoltaic panel 2 is increased, thereby improving the stability of the photovoltaic module 100 and the protection effect of the frame 1 to the photovoltaic panel 2.

[0099] Meanwhile, since the first extension section 12 extends away from the main body 11 along the bearing surface 113, and the second extension section 13 is arranged at the extension end of the first extension section 12, the second extension section 13 is used to protect the side edge of the photovoltaic panel 2.

The photovoltaic module 100 is also connected to the external support structure 200 through the main body 11, thereby further improving the stability of the photovoltaic module 100.

That is, by the fourth extending section 15, the damage of the photovoltaic panel 2 caused by the extrusion of the first extending section 12 and the second extending section 13 due to the possible deformation of the first extending section 12 and the second extending section 13 is avoided, the protection effect of the frame 1 on the photovoltaic panel 2 is further improved, and the external lines of the frame 1 are smoother due to the arc-shaped concave of the fourth extending section 15 towards the bearing surface 113, which avoids the rainwater deposition and damage of the photovoltaic module 100, avoids dirt accumulation, facilitates subsequent maintenance and cleaning, and makes the frame 1 more beautiful.

[0102] Fourthly, in the photovoltaic module 100 of the embodiment, the corner code 4 is inserted into the first frame 101 through the first inserting part 41, is inserted into the second frame 102 through the second inserting part 42, and the connecting piece 3 is connected to the corner code 4 by a bolt. The corner code 4 inserted into the frame 1 and the connecting piece 3 clamp the frame 1, and the two are matched, which not only facilitates the connection of the adjacent frames 1, but also makes the connection of the adjacent frames 1 more reliable. At the same time, since the corner code 4 is supported in the frame 1, the loosening of the connection of the adjacent frames 1 caused by the deformation and damage of the frame 1, or the damage of the photovoltaic panel 2 connected by the frame 1 is avoided, and therefore the installation and stability of the photovoltaic module 100 are further improved, and the installation cost is reduced.

[0103] Fifthly, in the photovoltaic system provided by the embodiment, the photovoltaic module 100 is connected to the support structure 200 through the frame 1, the first support piece 201 in the support structure 200 is connected to the frame 1 of the photovoltaic module 100, and under the action of the second support piece 202, the connection between the frame 1 and the first support piece 201 is strengthened, and the connection between the second support piece 202 and the adjacent frame 1 is also connected, so that the support of the support structure 200 on the photovoltaic module 100 is more comprehensive and balanced, the support force on the photovoltaic module 100 is more uniform when encountering external pressure, and the stability of the connection between the photovoltaic module 100 and the support structure 200 is improved.

[0104] At the same time, the adjacent frames 1 are connected to the same second support piece 202, which not only provides a solid support for the photovoltaic module 100, but also strengthens the connection between the adjacent frames 1, further enhances the stability of the connection between the adjacent frames 1, and improves the protection effect of the frame 1 on the photovoltaic panel 2.

[0105] Sixth, the number of the first support 201 in the photovoltaic module 100 proposed in the embodiment is two or more, the plurality of first supports 201 are evenly distributed on the back of the photovoltaic module 100, the plurality of first supports 201 evenly support the photovoltaic module 100, and the stability of the connection between the photovoltaic panel 2 and the support structure 200 is further improved; when the number of the first support 201 is two or more, the photovoltaic module 100 proposed in the embodiment is further provided with a reinforcing piece 203, the plurality of first supports 201 are connected through the reinforcing piece 203, the plurality of first supports 201 form a whole, the stability between the plurality of first supports 201 is enhanced, and the stability of the connection between the photovoltaic module 100 and the support structure 200 is further improved.
