[0002] Building Integrated Photovoltaic (BIPV) uses photovoltaic modules as building components or building materials, making them part of the building while also having power generation functions. BIPV can avoid occupying too much land resources, which is particularly important for urban buildings with expensive land. BIPV converts solar energy into electrical energy, can reduce the outdoor comprehensive temperature, and can also play a role in peak shaving for the power grid, achieving the effect of building energy conservation.

[0003] An installation frame is a support device for positioning photovoltaic modules. The installation frame is usually assembled by connecting multiple side frames. Corner fittings are used at the corners of the installation frame to connect and fix the side frames extending in different directions.

[0004] The corner fittings in related technologies are composed of an upper cover, a base body, and a lower cover, where the upper cover and the lower cover are respectively buckled on the upper and lower sides of the base body.

[0034] Figure 1It is an entity diagram of the corner fitting in the related art. The corner fitting 2 in the related art is composed of an upper cover 31, a base body 32 and a lower cover 33, wherein the upper cover 31 and the lower cover 33 are respectively buckled on the upper and lower sides of the base body 32. That is to say, the corner fitting 2 is assembled by three parts, and the installation process is relatively cumbersome, making it difficult to achieve automated production, which is not conducive to improving production efficiency. Moreover, under the condition that the corner fitting 2 is not installed with the frame, the upper cover 31 and the lower cover 33 may be separated from the base body 32 and scattered and dropped, which is not conducive to transportation and causes inconvenience to the transportation of the corner fitting 2 and the on-site construction.

[0035] Based on the above content, the present application provides a corner fitting assembly 1 to solve or at least partially alleviate the problems that the installation process of the corner fitting 2 in the related art is relatively cumbersome and the parts of the corner fitting 2 are prone to scatter during transportation. Figure 2 It is a schematic diagram of the corner fitting assembly 1 according to some embodiments of the present application.

[0036] One or more embodiments of the present application disclose a corner fitting assembly 1. Referring to Figure 2 and Figure 3 , the corner fitting assembly 1 includes a corner fitting base 10, the corner fitting base 10 is provided with a corner portion 13, an extension portion 14 and at least one stop portion 12, the extension portion 14 is arranged on the side of the corner portion 13, a receiving space 11 is defined between the corner portion 13 and the extension portion 14, the receiving space 11 is adapted to install the corner fitting body 20, the stop portion 12 is connected to the extension portion 14 and / or the corner portion 13, at least a part of the stop portion 12 extends axially, so as to be disposed opposite to the corner fitting body 20, and the corner fitting body 20 is buckled to the corner fitting base 10.

[0037] It can be understood that the corner fitting assembly 1 is composed of two parts, namely the corner fitting base 10 and the corner fitting body 20. On the basis of being easy to manufacture, the number of parts of the corner fitting assembly 1 is reduced, and the production cost is lowered; and the installation process is reduced, which is convenient for realizing the automated production of the corner fitting assembly 1 and is conducive to improving production efficiency. Further, the corner fitting base 10 is buckled to the corner fitting body 20 through the stop portion 12, so that the corner fitting base 10 and the corner fitting body 20 are kept fixedly connected, which is conducive to limiting the corner fitting body 20 and the corner fitting base 10 during transportation.

[0038] In some embodiments, referring to Figure 3, the extension part 14 includes an upper insertion plate 141 and a lower insertion plate 142. The upper insertion plate 141 is connected to the upper side of the corner part 13, and the lower insertion plate 142 is connected to the lower side of the corner part 13. The upper insertion plate 141 and the lower insertion plate 142 are arranged opposite to each other along the axial direction, and the stop part 12 is connected to the upper insertion plate 141 and / or the lower insertion plate 142. That is to say, an accommodation space 11 is defined between the corner part 13 and the upper insertion plate 141 and the lower insertion plate 142 connected to the corner part 13. At least part of the corner code main body 20 is accommodated in the accommodation space 11, that is, the corner code main body 20 is clamped between the upper insertion plate 141 and the lower insertion plate 142.

[0039] It can be understood that by arranging the upper insertion plate 141, the corner code main body 20 and the lower insertion plate 142 opposite to each other in the axial direction, the mating area between the corner code main body 20 and the corner code base 10 in the plane perpendicular to the axial direction can be increased, which is beneficial to improving the load-bearing capacity of the corner code base 10 and the corner code main body 20, and further improving the structural reliability of the corner code assembly 1.

[0040] In some embodiments, referring to Figure 3 and Figure 4 , the stop part 12 includes an extension section 121 and a stop section 122. The extension section 121 is connected to one end of the upper insertion plate 141 far from the corner part 13, and the extension direction of the extension section 121 is the same as the extension direction of the upper insertion plate 141, and / or the extension section 121 is connected to one end of the lower insertion plate 142 far from the corner part 13, and the extension direction of the extension section 121 is the same as the extension direction of the lower insertion plate 142; the stop section 122 extends axially from the end of the extension section 121. Under the condition that the corner code base 10 is installed on the corner code main body 20, the stop section 122 is arranged opposite to the end of the corner code main body 20, so that the corner code base 10 is buckled to the corner code main body 20.

[0041] It can be understood that the extension direction of the extension section 121 of the stop part 12 is the same as that of the extension part 14, which is beneficial to simplifying the structure of the corner code base 10, reducing the processing difficulty of the corner code base 10, and reducing the production cost of the corner code assembly 1. The stop section 122 of the stop part 12 is arranged opposite to the end of the corner code main body 20. Furthermore, through the cooperation of the stop part 12 and the corner part 13, it is beneficial to play a limiting role in multiple directions.

[0042] In some other embodiments, the stop part 12 is connected to the side of the upper insertion plate 141 or the lower insertion plate 142 opposite to the inner side surface 25 of the corner code main body 20, so that at least part of the stop part 12 is arranged opposite to the inner side surface 25 of the corner code main body 20. Furthermore, through the combined action of the corner part 13 and the stop part 12, the corner code main body 20 and the corner code base 10 can be kept fixedly connected.

[0043] In some other embodiments, the stopping portion 12 is connected to a side of the upper inserting plate 141 or the lower inserting plate 142 that is disposed opposite to the outer side surface 24 of the corner fitting main body 20, such that at least a part of the stopping portion 12 is disposed opposite to the outer side surface 24 of the corner fitting main body 20. Further, the outer side surface 24 of the corner fitting main body 20 has a stopping opening, and thus, by the mutual engagement of the stopping portion 12 and the stopping opening, the corner fitting main body 20 and the corner fitting base 10 are kept fixedly connected.

[0044] It is worth mentioning that only one stopping portion 12 may be provided on the upper inserting plate 141 or the lower inserting plate 142, or a plurality of spaced-apart stopping portions 12 may be provided. The present application does not make specific limitations thereto.

[0045] In some embodiments, referring to Figure 3 and Figure 4 , the upper inserting plate 141 includes a first upper inserting plate 1411 and a second upper inserting plate 1412, the lower inserting plate 142 includes a first lower inserting plate 1421 and a second lower inserting plate 1422. The first upper inserting plate 1411 and the first lower inserting plate 1421 extend from the corner portion 13 along a first direction, and the second upper inserting plate 1412 and the second lower inserting plate 1422 extend from the corner portion 13 along a second direction; the stopping portion 12 is connected to the first upper inserting plate 1411 and / or the first lower inserting plate 1421 and / or the second upper inserting plate 1412 and / or the second lower inserting plate 1422, and at least a part of the stopping portion 12 is disposed opposite to the corner fitting main body 20, such that the corner fitting main body 20 is snap-fitted to the corner fitting base 10.

[0046] In at least one embodiment, the first direction, the second direction, and the axial direction are perpendicular to each other pairwise. That is to say, the axial direction is parallel to the thickness direction of the photovoltaic module, the first direction is parallel to the extending direction of one set of opposite sides of the photovoltaic module, and the second direction is parallel to the extending direction of the other set of opposite sides of the photovoltaic module, so that the corner fitting assembly 1 and the frame of the photovoltaic module are attached to the edge of the photovoltaic panel.

[0047] In at least one embodiment, the corner fitting base 10 only has the first upper inserting plate 1411 and the first lower inserting plate 1421, and a stopping portion 12 is connected to the first upper inserting plate 1411, such that the structure of the corner fitting base 10 is simpler, which is beneficial to reducing the processing difficulty of the corner fitting base 10 and reducing the processing cost.

[0048] In at least one other embodiment, the corner fitting base 10 only has the second upper inserting plate 1412 and the second lower inserting plate 1422, a stopping portion 12 is connected to the second upper inserting plate 1412, and another stopping portion 12 is connected to the second lower inserting plate 1422, such that the structure of the corner fitting base 10 is simpler, which is beneficial to reducing the processing difficulty of the corner fitting base 10 and reducing the processing cost, and the corner fitting base 10 is snap-fitted to the corner fitting main body 20 through two stopping portions 12, which is beneficial to improving the connection reliability.

[0049] In at least one other embodiment, the corner bracket base 10 has a first upper insertion plate 1411 and a first lower insertion plate 1421, as well as a second upper insertion plate 1412 and a second lower insertion plate 1422. A stop portion 12 is connected to the first upper insertion plate 1411 or the first lower insertion plate 1421, so as to improve the connection reliability and connection strength between the corner bracket base 10 and the corner bracket body 20 on the basis of ensuring a relatively simple structure of the corner bracket base 10.

[0050] In at least one other embodiment, the corner bracket base 10 has a first upper insertion plate 1411 and a first lower insertion plate 1421, as well as a second upper insertion plate 1412 and a second lower insertion plate 1422. A stop portion 12 is connected to the first upper insertion plate 1411 or the first lower insertion plate 1421, and another stop portion 12 is connected to the second upper insertion plate 1412 or the second lower insertion plate 1422, which is beneficial to further improve the connection reliability and connection strength between the corner bracket base 10 and the corner bracket body 20.

[0051] It can be understood that by reducing the number of the stop portions 12, it is beneficial to simplify the structure of the corner bracket base 10, reduce the processing difficulty of the corner bracket base 10, and further reduce the production cost of the corner bracket assembly 1 on the basis of ensuring the fixed connection between the corner bracket base 10 and the corner bracket body 20. On the contrary, by increasing the number of the stop portions 12, it is beneficial to improve the connection reliability between the corner bracket base 10 and the corner bracket body 20. It is worth mentioning that the number and position of the stop portions 12 can be flexibly adjusted according to the use environment and specific requirements of the corner bracket assembly 1, which is beneficial to improving the application range of the corner bracket assembly 1.

[0052] In some embodiments, referring to Figure 1 、 Figure 5 and Figure 6 , the corner bracket body 20 includes a turning portion 21, a first main body portion 22 and a second main body portion 23. The first main body portion 22 extends from the turning portion 21 along a first direction, and the second main body portion 23 extends from the turning portion 21 along a second direction. When the corner bracket body 20 is installed on the corner bracket base 10, the first main body portion 22 is clamped between the first upper insertion plate 1411 and the first lower insertion plate 1421, and the second main body portion 23 is clamped between the second upper insertion plate 1412 and the second lower insertion plate 1422. The stop portion 12 on the corner bracket base 10 is disposed opposite to the first main body portion 22 and / or the second main body portion 23, so that the corner bracket base 10 is buckled to the corner bracket main body.

[0053] It can be understood that referring to Figure 1 , the turning portion 21 is installed and adapted to the corner portion 13. The first main body portion 22 is adapted to be clamped between the first upper insertion plate 1411 and the first lower insertion plate 1421, and the second main body portion 23 is adapted to be clamped between the second upper insertion plate 1412 and the second lower insertion plate 1422, so that the corner bracket body 20 is accommodated in the accommodation space 11 of the corner bracket base 10.

[0054] In some embodiments, referring to Figures 2 to 4 , the corner base 10 further includes a corner guard portion 15. The corner guard portion 15 is located above the corner portion 13 along the axial direction. The corner guard portion 15 has a cavity 151 for accommodating the corner of the photovoltaic panel, so as to protect the corner of the photovoltaic panel and reduce the risk of the corner of the photovoltaic panel being knocked and cracked.

[0055] In at least one embodiment, the corner guard portion 15 and the corner portion 13 are integrally formed. The corner portion 13 is L-shaped to be adapted to accommodate the turning portion 21 of the corner body 20; the corner guard portion 15 is L-shaped to be adapted to accommodate the corner of the photovoltaic panel.

[0056] In some embodiments, referring to Figure 3 and Figure 4 , a bevel 143 is provided at the end of the extension portion 14. From the side far from the corner portion 13 to the side close to the corner portion 13, the bevel 143 gradually expands outward in a direction away from the accommodation space 11, so as to guide the frame of the photovoltaic module to be sleeved on the corner assembly 1, which is beneficial to improving the construction efficiency.

[0057] It can be understood that, referring to Figure 4 , under the condition that the stop portion 12 is connected to the end of the extension portion 14, that is, under the condition that the stop portion 12 is connected to the end of the upper insertion plate 141 or the lower insertion plate 142, the bevel 143 is provided at the end of the stop portion 12. From the side far from the extension portion 14 to the side close to the extension portion 14, the bevel 143 gradually expands outward in a direction away from the accommodation space 11.

[0058] In some embodiments, referring to Figure 5 and Figure 6 , a guiding portion 28 is provided at the end of the corner body 20. Along the extending direction of the corner body 20, the guiding portion 28 gradually converges inward between the inner side surface 25 and the outer side surface 24 of the corner body 20, so as to guide the frame of the photovoltaic module to be sleeved on the corner assembly 1, which is beneficial to improving the construction efficiency.

[0059] In at least one embodiment, referring to Figure 2 , the extending length of the first main body portion 22 in the first direction is greater than the extending lengths of the first upper insertion plate 1411 and the first lower insertion plate 1421 in the first direction, and the extending length of the second main body portion 23 in the second direction is greater than the extending lengths of the second upper insertion plate 1412 and the second lower insertion plate 1422 in the first direction. Further, referring to Figure 4, the end of the first upper insertion plate 1411 is connected with a stop portion 12. The extending direction of the extension section 121 of the stop portion 12 is consistent with the extending direction of the first upper insertion plate 1411, and the end of the extension section 121 and the end of the first main body portion 22 are axially opposite. The stop section 122 extends axially from the end of the extension section 121. When the corner bracket base 10 is installed on the corner bracket main body 20, the stop section 122 is opposite to the end of the first main body portion 22, so that the corner bracket base 10 and the corner bracket main body 20 are buckled. Further, referring to Figure 6 , the stop section 122 includes a first stop wall 1221 and a second stop wall 1222 facing the corner bracket main body 20. The first stop wall 1221 is opposite to the end face of the first main body portion 22, and thus plays a role of limiting in the first direction through the cooperation of the first stop wall 1221 and the corner portion 13. The second stop wall 1222 is opposite to the guiding portion of the first main body portion 22, and thus plays a role of limiting in the first direction and the second direction through the cooperation of the second stop wall 1222 and the corner portion 13, so as to limit the corner bracket base 10 and the corner bracket main body 20, which is beneficial to avoiding the separation of the corner bracket base 10 and the corner bracket main body 20 during transportation.

[0060] It can be understood that the guiding portion 28 on the corner bracket main body 20 plays a guiding role in one direction for the installation frame, and the inclined surface 143 on the corner bracket base 10 plays a guiding role in another direction for the installation frame, so as to facilitate the construction personnel to sleeved the installation frame on the corner bracket assembly 1, which is beneficial to improving the installation efficiency.

[0061] In some embodiments, referring to Figure 5 and Figure 6 , the inner side surface 25 of the corner bracket main body 20 is provided with a serrated portion 26. When the frame of the photovoltaic module is arranged on the corner bracket assembly 1, the serrated portion 26 is adapted to abut against the frame of the photovoltaic module to increase the friction between the installation frame and the corner bracket assembly 1, which is beneficial to avoiding the separation of the installation frame and the corner bracket assembly 1.

[0062] In some embodiments, referring to Figure 5 and Figure 6 , a plurality of hollow areas 27 are spacedly arranged on the corner bracket main body 20, which is beneficial to reducing the weight of the corner bracket main body 20 on the basis of ensuring the structural strength of the corner bracket main body 20.

[0063] In at least one embodiment, the corner bracket main body 20 is formed by processing profiles, which is beneficial to further improving the production efficiency of the corner bracket main body 20 and reducing the production cost.

[0064] One or more embodiments of the present application also disclose a photovoltaic module.
