It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited to the embodiments described herein.

[0030] As one aspect of the present application, a segmented photovoltaic frame is provided.

[0031] like Figures 1 to 3 As shown, the segmented photovoltaic frame includes a top support plate 1, a bottom support plate 2, a connecting plate 3, a first inclined plate 21 and a second inclined plate 22, wherein the bottom support plate 2 is used to be installed on a bracket or a purlin.

[0032] The structures and connection relationship of the top support plate 1, the bottom support plate 2, the connecting plate 3 and the first inclined plate 21 are introduced below.

[0033] The top support plate 1 and the bottom support plate 2 are connected by a connecting plate 3, and the bottom support plate 2 is arranged opposite to the top support plate 1. The connecting plate 3 is located on the same side of the top support plate 1 and the bottom support plate 2, and one end of the top support plate 1 is integrally formed with the connecting plate 3, and the other end extends in a direction away from the connecting plate 3. One end of the bottom support plate 2 is integrally formed with the connecting plate 3, and the other end extends in a direction away from the connecting plate 3. It should be noted that the top support plate 1, the bottom support plate 2, and the connecting plate 3 are all plate-like structures, wherein the top support plate 1 and the bottom support plate 2 are arranged parallel to each other, and have the same width and length; and the cross plates 5 are arranged perpendicular to the top support plate 1 and the bottom support plate 2.

[0034] The top support plate 1, the bottom support plate 2 and the connecting plate 3 are combined to form a slot 4, and the opening of the slot 4 is opened in the direction away from the connecting plate 3; the edge of the photovoltaic laminate 8 is inserted into the slot 4 from the opening of the slot 4, and the edge of the photovoltaic component is in contact with the top support plate 1, the connecting plate 3 and the bottom support plate 2, which effectively improves the installation stability of the photovoltaic laminate 8.

[0035] The first inclined plate 21 is arranged on one side of the length direction of the bottom support plate 2; the first inclined plate 21 is in the shape of a right triangle or a right trapezoid. In the embodiment of the present application, the first inclined plate 21 is a right triangle structure. From the connection plate 3 to the opening direction of the card slot 4, the distance between the hypotenuse of the first inclined plate 21 and the bottom support plate 2 gradually increases. The bottom support plate 2 is also connected to a second inclined plate 22 on the side away from the first inclined plate 21 in the length direction; the second inclined plate 22 is in the shape of a right triangle or a right trapezoid. In the embodiment of the present application, the second inclined plate 22 is a right triangle structure. From the connection plate 3 to the opening direction of the card slot 4, the distance between the hypotenuse of the second inclined plate 22 and the bottom support plate 2 gradually increases. In the embodiment of the present application, in order to facilitate the production of the segmented photovoltaic frame, both ends of the segmented photovoltaic frame in the length direction are subjected to a bevel process. Therefore, the first inclined plate 21 and the second inclined plate 22 are located on both sides of the bottom support plate 2, and are both integrally formed with the bottom support plate 2.

[0036] In this embodiment, the edge of the photovoltaic laminate 8 is installed in the card slot 4 and abuts against the top support plate 1, the bottom support plate 2 and the connecting plate 3, which can improve the installation stability of the photovoltaic laminate 8 and make it more uniform in force; in addition, the two ends of the bottom support plate 2 are respectively provided with a first inclined plate 21 and a second inclined plate 22. Since the two ends of the segmented photovoltaic frame are both processed by the bevel cutting process in the embodiment of the present application, compared with the flat solid frame of the connecting plate 3 of the same length, the contact area between the segmented photovoltaic frame of the present application and the photovoltaic laminate 8 is larger, which can make the stress of the photovoltaic laminate 8 more uniform and improve the installation stability of the photovoltaic laminate 8. In addition, between every two adjacent segmented photovoltaic frames, the end of the first inclined plate 21 of one segmented photovoltaic frame away from the connecting plate 3 and the end of the other second inclined plate 22 away from the connecting plate 3 are close to each other and do not contact, forming a ventilation channel to form a narrow tube effect, which can greatly improve the convection heat dissipation effect of the photovoltaic laminate 8.

[0037] In an optional embodiment, the photovoltaic frame further includes a horizontal plate 5, which is located between the top support plate 1 and the bottom support plate 2, one end of the horizontal plate 5 is integrally formed with the connecting plate 3, and the other end extends in a direction away from the connecting plate 3. The top support plate 1, the horizontal plate 5 and a portion of the connecting plate 3 are enclosed to form a card slot 4. It should be noted that the length and width of the horizontal plate 5 are the same as those of the top support plate 1, and the horizontal plate 5 is arranged parallel to the top support plate 1 and the bottom support plate 2.

[0038] In this embodiment, the top support plate 1, the cross plate 5 and a part of the connecting plate 3 are enclosed to form a slot 4, and the edge of the photovoltaic laminate 8 is located in the slot 4. There is a distance between the photovoltaic laminate 8 and the bottom support plate 2, which reduces the contact between the bottom support plate 2 and the photovoltaic laminate 8 and can improve the heat dissipation effect of the photovoltaic laminate 8.

[0039] In an optional embodiment, the transverse plate 5 and the bottom support plate 2 are connected by a side plate 6, which is a plate-shaped structure, and has the same length as the transverse plate 5, one end of the side plate is integrally formed with the transverse plate 5, and the other end is integrally formed with the bottom support plate 2. In addition, the side plate 6 and the connecting plate 3 are arranged parallel to each other.

[0040] In this embodiment, the provision of the side panels 6 can improve the supporting force for the transverse panel 5 and further enhance the supporting effect for the photovoltaic laminate 8 .

[0041] In an optional embodiment, the transverse plate 5, the side plates 6, the bottom support plate 2 and a portion of the connecting plate 3 enclose a closed cavity 7, wherein openings at both ends of the closed cavity 7 are in communication with the outside.

[0042] In this embodiment, the horizontal plate 5, the side plate 6, the bottom support plate 2 and a part of the connecting plate 3 enclose a closed cavity 7, which can enhance the strength of the structure on the one hand, and reduce the production cost and the weight of the entire segmented photovoltaic frame on the other hand.

[0043] In an optional embodiment, an extension plate 23 is connected to one end of the bottom support plate 2 away from the connecting plate 3, and the extension plate 23 is connected to the first inclined plate 21 and the second inclined plate 22, wherein the extension plate 23 is located between the first inclined plate 21 and the second inclined plate 22. In the embodiment of the present application, the extension plate 23 is integrally formed with the bottom support plate 2, and the extension plate 23 is also integrally formed with the first inclined plate 21 and the second inclined plate 22.

[0044] In this embodiment, the setting of the extension plate 23 can, on the one hand, support the setting length of the first inclined plate 21 and the second inclined plate 22, further improving the ventilation effect of the narrow tube effect; on the other hand, it can increase the contact area between the bottom support plate 2 and the bracket or purlin, and improve the stability of the segmented photovoltaic frame installed on the bracket or purlin.

[0045] In an optional embodiment, a chamfer is provided at one end of the extension plate 23 away from the bottom support plate 2, thereby effectively reducing the possibility of damage caused by collision during the installation of the segmented photovoltaic frame.

[0046] In an optional embodiment, a plurality of heat dissipation holes are formed on the extension plate 23 .

[0047] In this embodiment, the heat dissipation holes are provided to further improve the heat dissipation effect of the photovoltaic laminate 8 .

[0048] As a second aspect of the utility model, a photovoltaic assembly is provided, comprising a photovoltaic laminate 8 and a segmented photovoltaic frame as in any of the aforementioned embodiments, wherein the number of the segmented photovoltaic frames is several, and the several segmented photovoltaic frames are clamped to the photovoltaic laminate 8.

[0049] In an optional embodiment, a heat dissipation channel 9 is formed between two adjacent segmented photovoltaic frames.

[0050] In this embodiment, since each segmented photovoltaic frame has a first inclined plate 21 and a second inclined plate 22, the heat dissipation channel 9 formed between two adjacent segmented photovoltaic frames has a narrow tube effect, has an excellent convection heat dissipation effect, and enhances the ventilation and heat dissipation of the assembly. In addition, the first inclined plate 21 and the second inclined plate 22 increase the lower side frame of the photovoltaic assembly, increase the contact area between the photovoltaic laminate 8 and the segmented photovoltaic frame relative to the flat-cut segmented photovoltaic frame, and increase the stress uniformity of the photovoltaic laminate 8. In the process of installing the photovoltaic laminate 8 on the segmented photovoltaic frame, when the spacing between each two adjacent segmented photovoltaic frames is small, the convection wind speed can be effectively enhanced, and the ventilation and heat dissipation effect of the photovoltaic module can be enhanced; when the spacing between each two adjacent segmented photovoltaic frames is large, the stress uniformity of the photovoltaic laminate 8 is required to be higher. Under the condition of the same outer spacing, relative to the flat-cut segmented photovoltaic frame, the segmented photovoltaic frame of the embodiment of the present application increases the contact area with the photovoltaic laminate 8, making the component stress more uniform, that is, the top support plate 1, the connecting plate 3 and the cross plate 5 of the segmented photovoltaic frame of the present application are in full contact with the photovoltaic laminate 8. In addition, a heat dissipation channel 9 is formed between two adjacent segmented photovoltaic frames, which can protect the edge of the photovoltaic laminate 8, make the stress more uniform, and reduce the risk of photovoltaic module rupture while achieving good heat dissipation effect.
