In the prior art, a photovoltaic module is fixed to a surface to be installed (such as a roof, an outer wall of a building, etc.) through a photovoltaic frame. The fixing method is to set lugs on the side of the photovoltaic frame and fix the lugs on the surface to be installed through screws. Since the lugs occupy a certain space, this installation method makes the edge position of the photovoltaic frame array unable to fit the edge of the surface to be installed (the space is occupied by the lugs), resulting in poor aesthetics after assembly. Summary of the Utility Model

[0025] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Such as Figure 1 and Figure 2As shown, an embodiment of a photovoltaic frame assembly installed using connecting blocks according to the present application includes a plurality of photovoltaic frames 10 arranged in an array, connecting blocks 20, and connecting members. Among them, the photovoltaic frame 10 is used to install the photovoltaic module 100. The photovoltaic frame 10 includes an outer support vertical wall 11, and the outer support vertical wall 11 forms the outer side surface of the photovoltaic frame 10. A first connection structure 111 is provided at the top of the outer support vertical wall 11, and the outer surface of the photovoltaic module 100 is flush with the top of the outer support vertical wall 11. The connecting block 20 is provided between two adjacent photovoltaic frames 10. Two second connection structures 21 and connection holes 22 are provided on the connecting block 20. The two second connection structures 21 are respectively provided on both sides of the connecting block 20 and are respectively matched with the first connection structures 111 of two adjacent photovoltaic frames 10. The connecting member is adapted to be connected to the surface to be installed after passing through the connection hole 22.

[0027] Using the technical solution of this embodiment, a connecting block 20 is provided between the outer support vertical walls 11 of adjacent photovoltaic frames 10. During assembly, the second connection structures 21 on both sides of the connecting block 20 are matched with the first connection structures 111 on the adjacent photovoltaic frames 10, and then the connecting member passes through the first connection hole 22 and is connected to the surface to be installed, locking the side part of the photovoltaic frame 10 on the surface to be installed. In the above structure, the position of the connecting block is set between adjacent photovoltaic frames 10. Therefore, the edge position of the assembled photovoltaic frame assembly can fit the surface to be installed, with a more beautiful appearance and a wide range of application scenarios. Therefore, the technical solution of this embodiment solves the defect that the edge of the photovoltaic frame in the prior art cannot fit the edge of the surface to be installed after assembly.

[0028] As Figure 1 and Figure 2 shown, the photovoltaic module 100 may include a bottom plate, components, a glass panel, etc., and the photovoltaic module 100 has a square structure. Accordingly, the photovoltaic frame 10 also forms a square frame, and the photovoltaic module 100 is assembled inside the photovoltaic frame 10.

[0029] From Figure 1 it can be seen that the photovoltaic frame 10 includes an outer support vertical wall 11, and the outer support vertical wall 11 is an annular wall, and its outer surface forms the outer side wall of the photovoltaic frame 10. Further, the outer surface of the photovoltaic module 100 (i.e., the outer wall surface of the glass plate) is flush with the top of the outer support vertical wall 11, that is, the photovoltaic frame 10 in this embodiment is a frameless A-side frame. The characteristic of the frameless A-side frame is that the outer surfaces of the photovoltaic frame 10 and the photovoltaic module 100 are flush, and dust can be washed out from the photovoltaic module 100 along with rainwater, preventing dust from accumulating on the photovoltaic module 100.

[0030] Those skilled in the art can understand that the outer surface of the outer support vertical wall 11 also forms the B-side of the photovoltaic frame 10.

[0031] From Figure 2 As can be seen, a first connection structure 111 is provided at the top of the outer support vertical wall 11.

[0032] When a plurality of photovoltaic frames 10 are assembled, the plurality of photovoltaic frames 10 are arranged in an array, and the array arrangement means forming a row and column arrangement. For example, six photovoltaic frames 10 are arranged in two rows and three columns, or three rows and two columns. Another example is that nine photovoltaic frames 10 are arranged in three rows and three columns, and so on.

[0033] As Figure 1 and Figure 2 shown, after the plurality of photovoltaic frames 10 are arranged in an array, the outer support vertical walls 11 in adjacent photovoltaic frames 10 are arranged opposite to each other. And there is a certain distance between adjacent photovoltaic frames 10, that is, there is a certain distance between adjacent outer support vertical walls 11. From Figure 1 and Figure 2 it can be seen that this distance is used to install the connecting clamp 20.

[0034] As Figure 1 and Figure 2 shown, during assembly, the connecting clamp 20 is assembled from top to bottom between adjacent photovoltaic frames 10. Among them, the second connection structure 21 on the connecting clamp 20 cooperates with the first connection structure 111 on the outer support vertical wall 11 from top to bottom. On the one hand, it has the effect of pressing down the photovoltaic frame 10, and on the other hand, it has the effect of limiting the photovoltaic frame 10 to prevent it from moving in the plane. The two second connection structures 21 on the connecting clamp 20 respectively cooperate with the first connection structures 111 of two adjacent photovoltaic frames 10.

[0035] Then, after the connecting piece passes through the connecting hole 22, it is connected to the surface to be installed. The surface to be installed can be an installation plate, a roof surface, a building side surface, etc. The connecting piece fixes the connecting clamp 20 on the surface to be installed and provides a fastening force to the connecting clamp 20. The connecting clamp 20 converts the fastening force into a pressing force on the photovoltaic frame 10 through the second connection structure 21, so as to press the photovoltaic frame 10 against the surface to be installed.

[0036] Furthermore, since two second connection structures 21 are provided on one connecting clamp 20, one connecting clamp 20 can press the sides of two adjacent photovoltaic frames 10.

[0037] As Figure 1 and Figure 2As shown, in the technical solution of this embodiment, one of the first connection structure 111 and the second connection structure 21 is a convex part, and the other is a concave part. Specifically, when the connecting block 20 is installed between adjacent photovoltaic frames 10 from top to bottom, the convex part is inserted into the concave part. The convex part and the concave part can limit the position of the photovoltaic frame 10, ensuring the relative position between the photovoltaic frame 10 and the connecting block 20 is fixed.

[0038] As Figure 2 shown, in the technical solution of this embodiment, the first connection structure 111 is a convex part, that is, the convex part is arranged at the top position of the outer support vertical wall 11. The second connection structure 21 is a concave part, and its opening direction faces downward, that is, towards the convex part.

[0039] In some embodiments not shown, the forms of the first connection structure 111 and the second connection structure 21 can also be swapped, that is, the first connection structure 111 is a convex part and the second connection structure 21 is a concave part, which is also a feasible implementation.

[0040] Furthermore, from Figure 2 it can also be seen that the inclination angle of the outer side wall surface of the convex part is smaller than that of the inner side wall surface. Correspondingly, the inclination angle of the wall surface of the concave part facing the inner side of the photovoltaic frame 10 is smaller than that of the wall surface facing the outer side of the photovoltaic frame 10. With such a setting, when the photovoltaic frame 10 has a tendency to move outward, the two wall surfaces with larger inclination angles can provide stable support and limiting force for the photovoltaic frame 10. And further, when assembling the connecting block 20, the lower end of the convex part abuts against the wall surface with a smaller inclination angle of the concave part, so that the convex part can be more quickly guided into the concave part, facilitating assembly.

[0041] As Figure 1 and Figure 2 shown, in the technical solution of this embodiment, the connecting block 20 includes a bottom wall 23 and two side walls 24 respectively arranged on both sides of the bottom wall 23. The connecting hole 22 is arranged on the bottom wall 23. The side wall 24 cooperates with the outer support vertical wall 11, and the second connection structure 21 is arranged at the top of the side wall 24.

[0042] Specifically, the side wall 24 is perpendicular to the bottom wall 23, so the cross-section of the connecting block 20 is generally in a "C" - shaped structure with an upward opening. The distance between the outer side surfaces of the two side walls 24 is slightly smaller than the distance between the outer support vertical walls 11 of adjacent two photovoltaic frames 10. Therefore, during assembly, the bottom wall 23 and the side walls 24 can be installed downward between adjacent photovoltaic frames.

[0043] Further, the above-mentioned connecting holes 22 are provided in the middle of the bottom wall 23, and are located at a position slightly lower than the middle of the photovoltaic frame 10 after assembly. The two second connecting structures 21 are respectively provided on the two side walls 24. During the assembly process, the second connecting structure 21 cooperates with the first connecting structure 111 downward.

[0044] As Figure 1 and Figure 2 shown, in the technical solution of this embodiment, a flanging structure 25 is provided at the top of the side wall 24, and the second connecting structure 21 is provided on the lower side of the flanging structure 25.

[0045] Specifically, the flanging structure 25 is folded outward toward the side wall 24, and the second connecting structure 21, that is, the convex part, is provided on the lower side of the flanging structure 25, so that the convex part can protrude toward the concave part. As Figure 2 can also be seen, during assembly, the lower surface of the flanging structure 25 abuts against the top of the outer support vertical wall 11, so that the installation depth of the connecting pressure block 20 can also be limited.

[0046] Further, flanging structures 25 are provided on both side walls 24, and the folding directions of the two flanging structures 25 are opposite.

[0047] Further, the connecting pressure block 20 has a strip-shaped structure. Specifically, since each side of the photovoltaic frame 10 is a long side, the connecting pressure block 20 is provided with a strip-shaped structure. Those skilled in the art can understand that Figure 1 and Figure 2 shown is a cross-sectional view of the connecting pressure block 20, and the above-mentioned bottom wall 23, side wall 24, flanging structure 25 and second connecting structure 21 are all strip-shaped structures.

[0048] After assembly, the connecting pressure block 20 can press a whole long side of the photovoltaic frame 10.

[0049] Further, since the photovoltaic frame assembly is usually placed obliquely (toward the sunlight direction), the connecting pressure block 20 extends along the inclined direction of the photovoltaic frame assembly. With this setting, after the dust on the photovoltaic module 100 is washed by rainwater, it can slide down along the inclined surface of the photovoltaic module 100 and be discharged. Since the extending direction of the connecting pressure block 20 is the inclined direction of the photovoltaic frame assembly, it does not block the flow and discharge of rainwater and dust, and prevents dust from accumulating at the corners of the photovoltaic module 100 and the flanging structure 25.

[0050] Optionally, the connecting piece includes a connecting screw. After passing through the connecting hole 22, the connecting screw is connected to the surface to be installed. The connecting screw applies a fastening force to the connecting pressure block 20, and the connecting pressure block 20 converts the fastening force into a pressing force on the photovoltaic frame 10.

[0051] As Figure 1 and Figure 3As shown, in the technical solution of this embodiment, the photovoltaic frame 10 further includes a supporting top wall 12. The supporting top wall 12 is connected to the inner side of the outer supporting vertical wall 11. The top of the outer supporting vertical wall 11 protrudes above the supporting top wall 12. The outer supporting vertical wall 11 and the supporting top wall 12 enclose an installation groove 30, and the edge of the photovoltaic module 100 is installed in the installation groove 30.

[0052] Specifically, the supporting top wall 12 is of a frame structure. Its outer end is connected to the inner side of the outer supporting vertical wall 11, and its inner end extends towards the inner side of the photovoltaic frame 10. The supporting top wall 12 is lower than the top of the outer supporting vertical wall 11, so that an installation groove 30 is formed between the supporting top wall 12 and the outer supporting vertical wall 11. During assembly, the upper surface of the supporting top wall 12 supports the bottom surface of the edge of the photovoltaic module 100, and the inner side of the outer supporting vertical wall 11 cooperates with the side surface of the photovoltaic module 100.

[0053] As Figure 3 shown, in the technical solution of this embodiment, the installation groove 30 includes a bottom surface 31 and a side surface 32. Glue filling grooves 40 are provided on the bottom surface 31 and the side surface 32, and the wall surfaces of the glue filling grooves 40 are concave-convex surfaces.

[0054] Specifically, as described above, since the photovoltaic frame 10 in this embodiment is a borderless A-surface frame, glue is required to bond the photovoltaic module 100 to the photovoltaic frame 10. As Figure 2 can be seen, the top surface of the supporting top wall 12 forms the bottom surface 31 of the installation groove 30. The upper side of the outer supporting vertical wall 11 protrudes above the supporting top wall 12, and this protruding part forms the side surface 32 of the installation groove 30 towards the inner side of the photovoltaic frame 10.

[0055] Furthermore, glue filling grooves 40 are provided on both the bottom surface 31 and the side surface 32. After the glue solidifies, it can connect the photovoltaic module 100 to the bottom surface 31 and the side surface 32, thereby fixing the photovoltaic module 100 to the photovoltaic frame 10.

[0056] Since the wall surfaces of the glue filling grooves 40 are concave-convex surfaces, the contact area between the glue and the glue filling grooves 40 can be increased, so that the bonding force between the glue and the bottom surface 31 and the side surface 32 is stronger, making the connection between the photovoltaic module 100 and the photovoltaic frame 10 more stable.

[0057] Optionally, the above-mentioned concave-convex surfaces can be wavy surfaces, toothed surfaces, rough surfaces, etc.

[0058] As Figure 1 and Figure 3 shown, in the technical solution of this embodiment, the photovoltaic frame 10 further includes an inner supporting vertical wall 13 and a supporting bottom wall 14. The inner supporting vertical wall 13 is connected to the lower side of the supporting top wall 12 and is located inside the outer supporting vertical wall 11. The supporting bottom wall 14 is connected below the outer supporting vertical wall 11 and the inner supporting vertical wall 13.

[0059] From Figure 1 It can be seen that the inner support vertical wall 13 is connected below the support top wall 12, playing a supporting role for the support top wall 12. The inner support vertical wall 13 is opposite to the outer support vertical wall 11 and is arranged in parallel. From Figure 3 It can also be seen that the inner end of the support top wall 12 protrudes inwards beyond the inner support vertical wall 13, so that the width of the bottom surface 31 of the installation groove 30 is as wide as possible, increasing the contact area between the glue and the bottom surface 31 and increasing the bonding force between the glue and the bottom surface 31.

[0060] From the structure Figure 1 It can be seen that the support bottom wall 14 is connected below the outer support vertical wall 11 and the inner support vertical wall 13. The support bottom wall 14 is parallel to the support top wall 12 and perpendicular to the outer support vertical wall 11 and the inner support vertical wall 13. Those skilled in the art can understand that the bottom surface of the support bottom wall 14 forms the C surface of the photovoltaic frame 10. The outer end of the support bottom wall 14 is connected to the outer support vertical wall 11, and the inner end extends to protrude beyond the inner support vertical wall 13.

[0061] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
