[0041] Refer to Figure 1 、 2As shown in the figure, an embodiment of the present application provides a photovoltaic module frame joint buckle 1, which includes a buckle main body 11 and a buckle abutting portion 12. The buckle abutting portion 12 is located at one end of the buckle main body 11. The buckle abutting portion 12 has two first abutting surfaces 121, and the two first abutting surfaces 121 are respectively used to abut against two adjacent sides of the photovoltaic module frame 2. Both of the two first abutting surfaces 121 are inclined surfaces, and in the direction gradually away from the buckle main body 11, the width of the buckle abutting portion 12 gradually decreases. A through groove 13 is provided on the photovoltaic module frame joint buckle 1, and the through groove 13 penetrates through the buckle main body 11 and the buckle abutting portion 12 along the length direction of the buckle main body 11.

[0042] The above-mentioned photovoltaic module frame joint buckle 1 can be used to connect two adjacent sides of the photovoltaic module frame 2. When connecting two adjacent sides of the photovoltaic module frame 2 through the photovoltaic module frame joint buckle 1, the buckle abutting portion 12 can be arranged towards the inner side of the photovoltaic module frame 2, and the parts on two adjacent sides of the photovoltaic module frame 2 for connecting with the photovoltaic module frame joint buckle 1 can be placed in the through groove 13, and then the photovoltaic module frame joint buckle 1 is pushed until the two first abutting surfaces 121 of the buckle abutting portion 12 respectively abut against the inner side surfaces of two adjacent sides of the photovoltaic module frame 2, so as to realize the connection and fixation of two adjacent sides of the photovoltaic module frame 2. Compared with the traditional connection method using corner brackets, the photovoltaic module frame joint buckle 1 can simplify the assembly process.

[0043] It can be understood that the photovoltaic module frame joint buckle 1 of the present application can be applied to the connection between any two adjacent sides of the photovoltaic module frame 2 with all sides being segmented, and can also be applied to the connection between two sides at the joint position of the photovoltaic module frame 2 formed by folding and enclosing. When connecting two sides at the joint position of the photovoltaic module frame 2 formed by folding and enclosing through the photovoltaic module frame joint buckle 1 of the present application, since both of the two first abutting surfaces 121 are inclined surfaces, in the direction gradually away from the buckle main body 11, the width of the buckle abutting portion 12 gradually decreases, so that the photovoltaic module frame joint buckle 1 can be arranged at the corner of the photovoltaic module frame 2. Compared with the photovoltaic module frame with the joint position located in the middle of one side, the above connection method can improve the airborne strength of the photovoltaic module frame 2.

[0044] Refer to again Figure 1 、 Figure 2 As shown in the figure, exemplarily, Figure 1 、 Figure 2 the X direction in

[0045] In some embodiments, the two first abutting surfaces 121 form a 45° angle.

[0046] The two first abutting surfaces 121 form a 45° angle, facilitating the abutment of the buckle main body 11 against the right-angle corner of the photovoltaic module frame 2.

[0047] In some embodiments, the two first abutting surfaces 121 are connected on the side away from the buckle main body 11 to form a tip structure. The buckle abutting portion 12 with the above structure can be fully attached to the corner of the photovoltaic module frame 2, achieving a better fixing effect.

[0048] In some embodiments, the through slot 13 includes a relief portion 131 and a guiding portion 132. The guiding portion 132 opens at the bottom surface. The width of the relief portion 131 is greater than the width of the guiding portion 132.

[0049] Refer again to Figure 1 、 Figure 2 As shown, by way of example, Figure 1 、 Figure 2 the Z direction in

[0050] is the width direction of the relief portion 131. When the photovoltaic module frame joint buckle 1 with the above structure is in use, it can be provided with a component extending along the width direction of the relief portion 131 in the photovoltaic module frame 2, and the component is arranged in the relief portion 131, which can provide a downward limiting effect on the photovoltaic module frame joint buckle 1 and improve the fixing effect of the photovoltaic module frame joint buckle 1.

[0051] In some embodiments, the photovoltaic module frame joint buckle 1 further includes a reinforcement portion 14. The reinforcement portion 14 is arranged on the surface of the buckle abutting portion 12 opposite to the bottom surface. The reinforcement portion 14 has two second abutting surfaces 141, and the two second abutting surfaces 141 are flush with the two first abutting surfaces 121 respectively.

[0052] Refer again to Figure 1 、 Figure 2 As shown, by way of example, Figure 1 、 Figure 2 the Z direction in

[0053] is the thickness direction of the buckle abutting portion 12. By abutting the two second abutting surfaces 141 against the adjacent sides of the photovoltaic module frame 2, the contact area between the photovoltaic module frame joint buckle 1 and the adjacent sides of the photovoltaic module frame 2 can be increased, enabling the photovoltaic module frame joint buckle 1 to have a better fixing effect. Figure 4 、 Figure 7As shown in the figure, another embodiment of the present application provides a photovoltaic module frame 2, including the photovoltaic module frame joint buckle 1 of any one of the above and a plurality of main members 21. Guide members 210 are provided on at least two cooperatively connected main members 21, and the two main members 21 can be cooperatively connected with the through slot 13 in the photovoltaic module frame joint buckle 1 through the guide members 210 for snap connection.

[0054] When connecting two cooperatively connected main members 21 in the photovoltaic module frame 2 through the photovoltaic module frame joint buckle 1, the buckle abutting portion 12 can be arranged towards the inner side of the photovoltaic module frame 2, and the guide members 210 of the two cooperatively connected main members 21 can be simultaneously placed in the through slot 13, and then the photovoltaic module frame joint buckle 1 is pushed along the guide member 210 until the two first abutting surfaces 121 of the buckle abutting portion 12 respectively abut against the inner side surfaces of the two cooperatively connected main members 21, so as to realize the connection and fixation of the two adjacent main members 21.

[0055] Refer to Figures 3 - 5 As shown in the figure, in some embodiments, the two side surfaces of the main member 21 along its length direction are third abutting surfaces 23, each third abutting surface 23 is an inclined surface, and the outer length of the main member 21 is greater than the inner length. The photovoltaic module frame 2 further includes a plurality of connecting members 22, and the plurality of main members 21 are sequentially connected through the connecting members 22, and guide members 210 are respectively provided on the main members 21 at both ends. Each main member 21 can form a closed-loop structure by bending the connecting member 22. After each main member 21 is enclosed, the third abutting surfaces 23 of two adjacent main members 21 abut against each other.

[0056] Refer to Figure 4 As shown in the figure, during assembly, the connecting member 22 can be bent to make the relatively arranged third abutting surfaces 23 of adjacent main members 21 move towards each other until they abut against each other, so that the main members 21 arranged in sequence along the length direction of the main member 21 are connected end to end, thereby enclosing the photovoltaic module frame 2 with a closed-loop structure. After each main member 21 is enclosed, the third abutting surfaces 23 of two adjacent main members 21 abut against each other. That is, each third abutting surface 23 in the photovoltaic module frame 2 can form an enclosed photovoltaic module frame 2 by bending the connecting member 22. The above photovoltaic module frame 2 can be formed by folding, the assembly process is simple, and only one photovoltaic module frame joint buckle 1 is needed to connect and fix the two main members 21 at the joint position to complete the assembly of the photovoltaic module frame 2. Compared with the traditional segmented photovoltaic module frame connected by four corner codes, the photovoltaic module frame of the present application can be assembled by folding and one photovoltaic module frame joint buckle 1, and the assembly process is simple.

[0057] It can be understood that the inner side of the main body member 21 refers to the side where the photovoltaic module frame 2 and the photovoltaic laminate 3 cooperate after the main body members 21 are enclosed, and the outer side of the main body member 21 refers to the side of the photovoltaic module frame 2 away from the photovoltaic laminate 3 after the main body members 21 are enclosed, that is, the outermost side in the photovoltaic module.

[0058] It can be understood that each of the third abutting surfaces 23 is an inclined surface, so that the outer side length of the main body member 21 is greater than the inner side length, which can make Figure 3 As shown, the orthographic projection of the main body member 21 in its height direction is a trapezoid, so that each main body member 21 can be folded inward to form a photovoltaic module frame 2 with a closed-loop structure.

[0059] Referring again to Figure 3 shown, by way of example, Figure 3 the A direction in Figure 3 is the length direction of the main body member 21. The B direction in Figure 3 is the direction perpendicular to the paper plane. By way of example, Figures 3 - 6 the B direction in

[0060] is the height direction of the main body member 21. It can be understood that in this application,

[0061] are all schematic diagrams of the outline of the orthographic projection of the photovoltaic module frame 2 in its height direction, that is, the schematic diagram of the top view in the direction perpendicular to the paper plane.

[0062] In some embodiments, the connecting member 22 is connected to the relatively arranged third abutting surfaces 23 of two adjacent main body members 21.

[0063] Taking the photovoltaic module frame 2 with the above structure as a specific example, including three connecting members 22 and four main body members 21, a square photovoltaic module frame 2 can be enclosed. When assembling the above photovoltaic module frame 2, the connecting member 22 can be bent in sequence to make the third abutting surfaces 23 of two adjacent main body members 21 abut against each other, so as to form three corners of the enclosed photovoltaic module frame 2. At the same time, through the bending of the connecting member 22, the three corners of the formed photovoltaic module frame 2 can be arc-shaped corners, which can increase the aesthetics of the photovoltaic module frame 2 while reducing the bumps at the right-angle corners. Finally, the main body members 21 arranged in sequence along the length direction of the main body member 21 are connected end to end, that is, the two third abutting surfaces 23 with the farthest distance are made to abut against each other to form a completely enclosed photovoltaic module frame 2.

[0064] In some of these embodiments, the photovoltaic module frame 2 includes two first main members and two second main members. The length of the first main member is greater than that of the second main member. The first main members and the second main members are arranged alternately. The above-mentioned photovoltaic module frame 2 can enclose to form a rectangular photovoltaic module frame 2.

[0065] In some of these embodiments, each of the third abutting surfaces 23 of each main member 21 is the same.

[0066] Referring to Figure 6 As shown, in some of these embodiments, at least one set of the cooperating third abutting surfaces 23 are respectively provided with a protruding portion 24 and a recessed portion 25 for cooperating and engaging.

[0067] If the third abutting surface 23 is a smooth surface without a protruding portion 24 or a recessed portion 25, in the enclosed photovoltaic module frame, when the adjacent main members 21 are misaligned and stressed, it is easy to cause deformation and separation between the adjacent main members 21, thus causing the failure of the photovoltaic module frame. By providing the cooperating protruding portion 24 and recessed portion 25 on the third abutting surface 23, the firmness of the enclosed main members 21 can be increased, and the risk of deformation and separation between the adjacent main members 21 can be reduced. It can be understood that only a protruding portion 24 or a recessed portion 25 can be provided on a single third abutting surface 23, or both a protruding portion 24 and a recessed portion 25 can be provided at the same time. If only a protruding portion 24 is provided on a third abutting surface 23, then at the corresponding position on the third abutting surface 23 that abuts against it after enclosure, a recessed portion 25 with the same number is provided. If both a protruding portion 24 and a recessed portion 25 are provided on a third abutting surface 23 at the same time, then on the third abutting surface 23 that abuts against it after enclosure, a recessed portion 25 and a protruding portion 24 are provided in one-to-one correspondence.

[0068] It can be understood that the shape of the protruding portion 24 can be a regular shape or an irregular shape, and the shape of the recessed portion 25 is adapted to the corresponding protruding portion 24.

[0069] In some of these embodiments, the orthographic projection of the protruding portion 24 along the height direction of the main member 21 is semi-circular.

[0070] In some of these embodiments, multiple sets of protruding portions 24 and recessed portions 25 are provided on each set of the cooperating third abutting surfaces 23. The protruding portions 24 and the recessed portions 25 are arranged at intervals on each third abutting surface 23.

[0071] The protruding portions 24 and the recessed portions 25 are arranged at intervals on each third abutting surface 23, which can further increase the fixing effect between the adjacent main members 21.

[0072] In some of these embodiments, on a single third abutting surface 23, the total number of the protruding portions 24 and the recessed portions 25 is from 2 to 10.

[0073] Optionally, on a single third abutting surface 23, the total number of the protruding portions 24 and the recessed portions 25 is 2, 3, 4, 5, 6, 7, 8, 9, or 10.

[0074] In some of these embodiments, on a single third abutting surface 23, the protruding portions 24 and the recessed portions 25 are arranged alternately.

[0075] In some of these embodiments, each third abutting surface 23 forms an angle of 45° with the length direction of the main body member 21.

[0076] In some of these embodiments, the connecting member 22 and the main body member 21 are integrally formed.

[0077] It can be understood that the photovoltaic module frame 2 of the present application can obtain a strip-shaped pre-finished photovoltaic module frame through integral forming, and then cut the pre-finished photovoltaic module frame to form the third abutting surface 23, so as to obtain a photovoltaic module frame 2 that can be assembled by folding.

[0078] Referring to Figure 5 As shown, in some of these embodiments, the surface of the connecting member 22 facing the inner side of the main body member 21 is an arc surface.

[0079] Exemplarily, Figure 5 in a, a is the surface of the connecting member 22 facing the inner side of the main body member 21. The surface of the connecting member 22 facing the inner side of the main body member 21 is an arc surface, which facilitates bending the connecting member 22 to form a photovoltaic module frame with an arc-shaped corner.

[0080] Referring to Figure 7 、 Figure 8 As shown, in some of these embodiments, the main body member 21 includes a partition plate 211, side plates 212, a bottom plate 213, a mounting plate 214, and a support plate 219. The bottom plate 213 and the mounting plate 214 are spaced apart and oppositely arranged on the side plates 212. The support plate 219 is arranged on the surface of the bottom plate 213 away from the mounting plate 214. The surface of the support plate 219 away from the mounting plate 214 is used to support the photovoltaic laminate 3. The partition plate 211 is arranged on the surface of the bottom plate 213 away from the mounting plate 214. The partition plate 211, the bottom plate 213, and the support plate 219 enclose a caulking groove 218. The portion of the side plate 212 protruding from the surface of the bottom plate 213 away from the mounting plate 214, the bottom plate 213, and the partition plate 211 enclose a card slot 217. The guide rail member 210 is arranged on the surface of the mounting plate 214 facing the bottom plate 213.

[0081] In some embodiments, the photovoltaic module frame 2 further includes a clamping member 26. The clamping slot 217 is used to install the clamping member 26. The clamping member 26 is used to fix the photovoltaic laminate 3 to the photovoltaic module frame 2.

[0082] The above embodiment shows an embodiment of the main body 21, that is, the photovoltaic laminate 3 is supported by the support plate 219, and the clamping member 26 is installed through the clamping groove 217, and the clamping member 26 is used to fix the photovoltaic laminate 3 to the photovoltaic component frame 2 on the photovoltaic component frame 2. It can be understood that Figure 8 It is a cross-sectional view along the height direction of the main body 21. The foldable photovoltaic module frame 2 of the present application is suitable for the photovoltaic module frame 2 with the above structure. When in use, the photovoltaic module frame 2 can be first folded to form an enclosed photovoltaic module frame 2, and then the photovoltaic laminate 3 can be installed and fixed, which is convenient for the assembly of the photovoltaic module.

[0083] In some embodiments, the through slot 13 includes a yielding portion 131 and a guide portion 132. Compared with the yielding portion 131, the guide portion 132 is closer to the notch of the through slot 13. The width of the guide portion 132 is greater than the width of the yielding portion 131. The guide rail member 210 includes a first sub-portion and a second sub-portion. The first sub-portion is disposed on the surface of the mounting plate 214 facing the bottom plate 213. The second sub-portion is disposed on the side of the first sub-portion, and the second sub-portion and the mounting plate 214 are spaced apart. When the guide rail member 210 is engaged with the through slot 13, the two first sub-portions pass through the guide portion 132 and extend into the yielding portion 131. Both second sub-portions are disposed in the yielding portion 131.

[0084] The guide rail member 210 having the above structure can be adapted to the through groove 13 including the yielding portion 131 and the guide portion 132. When the guide rail member 210 of the photovoltaic module frame joint buckle 1 and two adjacent main members 21 are connected, the two second sub-parts located in the yielding portion 131 can provide a downward limiting effect on the photovoltaic module frame joint buckle 1, thereby improving the fixing effect of the photovoltaic module frame joint buckle 1.

[0085] In some embodiments, the photovoltaic module frame 2 further includes a stopper 2101. The stopper 2101 is disposed on a surface of the guide rail 210 away from the mounting plate 214. When the guide rail 210 is engaged with the through slot 13, the stopper 2101 abuts against an end of the buckle body 11 away from the buckle abutment portion 12.

[0086] Reference Figure 7 , Figure 8As shown, in some of these embodiments, the main body member 21 further includes a connecting plate 215. One side of the connecting plate 215 is connected to the bottom plate 213, and the other side is connected to the mounting plate 214. The connecting plate 215 is disposed opposite to the side plate 212 with a space therebetween. A cavity 216 is formed among the connecting plate 215, the mounting plate 214, the side plate 212, and the bottom plate 213.

[0087] In some of these embodiments, the maximum height of the partition plate 211 from the bottom plate 213 is greater than or equal to the maximum height of the support plate 219 from the bottom plate 213.

[0088] Referring to Figure 8 As shown, exemplarily, Figure 8 In [reference], H1 is the maximum height of the partition plate 211 from the bottom plate 213, and H2 is the maximum height of the support plate 219 from the bottom plate 213. When the maximum height of the partition plate 211 from the bottom plate 213 is equal to the maximum height of the support plate 219 from the bottom plate 213, the back panel 32 of the photovoltaic laminate 3 can be supported and positioned by the surface of the partition plate 211 away from the bottom plate 213. When the maximum height of the partition plate 211 from the bottom plate 213 is greater than the maximum height of the support plate 219 from the bottom plate 213, the side surface of the back panel 32 of the photovoltaic laminate 3 abuts against the side surface of the partition plate 211.

[0089] In some of these embodiments, the side surface of the partition plate 211 has a recessed area that matches the side surface of the back panel 32 of the photovoltaic laminate 3 to abut against the side surface of the back panel 32.

[0090] In some of these embodiments, the support plate 219 includes a third sub - portion and a fourth sub - portion. The third sub - portion is disposed on the bottom plate 213 and protrudes from the surface of the bottom plate 213 away from the mounting plate 214. The partition plate 211, the bottom plate 213, and the third sub - portion enclose a glue - filling groove 218. The fourth sub - portion is connected to the third sub - portion and extends in a direction away from the partition plate 211. The surface of the fourth sub - portion away from the bottom plate 213 is used to support the photovoltaic laminate 3.

[0091] Another embodiment of the present application provides a photovoltaic module, including the photovoltaic module frame 2 according to any one of the above, and a photovoltaic laminate 3. The photovoltaic module frame 2 surrounds the outer periphery of the photovoltaic laminate 3.

[0092] See Figure 8As shown, the photovoltaic laminate 3 is fixed by the support plate 219, the partition plate 211, and the clamping member 26. Specifically, the back panel 32 of the photovoltaic laminate 3 abuts against the surface of the support plate 219 away from the bottom plate 213, and the side surface of the back panel 32 of the photovoltaic laminate 3 abuts against the side surface of the partition plate 211. The side surface of the partition plate 211 has a recessed area that matches the side surface of the back panel 32 of the photovoltaic laminate 3 to accommodate the side surface of the back panel 32. The side surface of the front panel 31 of the photovoltaic laminate 3 abuts against the side surface of the clamping member 26. One side of the clamping member 26 away from the bottom plate 213 extends towards the photovoltaic laminate 3, and the side surface of the clamping member 26 matches the side surface of the front panel 31 of the photovoltaic laminate 3.

[0093] In some embodiments, the distance between the support plate 219 and the surface of the clamping member 30 away from the bottom plate 213 is less than or equal to the thickness of the photovoltaic laminate 3.

[0094] Referring to Figure 8 As shown, Figure 8 In [reference], H3 is the distance between the support plate 219 and the surface of the clamping member 26 away from the bottom plate 213. When the distance between the support plate 219 and the surface of the clamping member 26 away from the bottom plate 213 is equal to the thickness of the photovoltaic laminate 3, the surface of the clamping member 26 away from the bottom plate 213 is lower than or flush with the upper surface of the front panel 31 of the photovoltaic laminate 3, which can reduce the dust accumulation on the front side of the photovoltaic laminate 3.

[0095] In some embodiments, the photovoltaic laminate 3 includes a front panel 31, a first adhesive layer, a solar cell, a second adhesive layer, and a back panel 32 stacked. At least one side edge of the back panel 32 protrudes beyond the corresponding side edge of the front panel 31.

[0096] The above-mentioned photovoltaic laminate 3 can be applied to the photovoltaic module frame 2 without an A side to reduce the dust accumulation of the photovoltaic module. At the same time, the part of the back panel 32 protruding beyond the edge of the front panel 31 can also provide a stress point. By applying pressure to the surface of the back panel 32 exposed beyond the front panel 31, the fixing effect on the photovoltaic laminate 3 can be improved, and the airborne strength can be enhanced.

[0097] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0098] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims, and the description and drawings can be used to explain the content of the claims.
