[0044] Reference Figure 1 、 Figure 5 The photovoltaic module 200 provided in the embodiment of the present application includes a photovoltaic laminate 40 , a photovoltaic module frame 100 and a support member 50 .

[0045] The photovoltaic module frame 100 is constructed in a closed shape, used to surround and position the photovoltaic laminate 40. The photovoltaic module frame 100 includes two first sub-frames 20 arranged opposite each other. The ends of the support member 50 are respectively connected to the two first sub-frames 20. The support member 50 has a support surface 51 configured to support the photovoltaic laminate 40 positioned in the photovoltaic module frame 100.

[0046] By making the photovoltaic component frame 100 include two oppositely arranged first sub-frames 20, and making the two ends of the support member 50 respectively connected to the two first sub-frames 20, the two opposite first sub-frames 20 are connected by the support member 50 to strengthen the strength, which will improve the strength of the photovoltaic component frame 100 and improve the stability of the support for the photovoltaic laminate 40, thereby improving the overall reliability of the photovoltaic component.

[0047] In addition, the support member 50 is provided with a support surface 51, and the support surface 51 is configured to support the photovoltaic laminate 40 positioned on the photovoltaic module frame 100. In addition to the support of the photovoltaic laminate 40 by the photovoltaic module frame 100, the support surface 51 also supports the portion of the photovoltaic laminate 40 located between the two first sub-frames 20, thereby avoiding the photovoltaic laminate 40 from being dented or deformed in the portion between the two first sub-frames 20, thereby strengthening the support of the photovoltaic module frame 100 for the photovoltaic laminate 40, thereby improving the reliability of the photovoltaic module.

[0048] In the embodiment of the present application, the first sub-frame 20 is described as a strip-shaped, integrally formed structure. In a specific implementation, the shape of the first sub-frame 20 can also be a curved shape, as long as it matches the edge shape of the photovoltaic laminate 40. In addition, the first sub-frame 20 can also include multiple frame segments formed separately, and the multiple frame segments are sequentially connected to form the first sub-frame 20. Of course, a support member 50 can be connected between the frame segments facing each other in two first sub-frames 20.

[0049] In addition, the photovoltaic laminate 40 can be, for example, a single-glass component or a double-glass component. The support member 50 can extend continuously along the opposite direction of the two first sub-frames 20, so as to support the entire photovoltaic laminate 40 along this direction, and in particular, better support the middle portion that is most susceptible to deformation.

[0050] Furthermore, the support surface 51 contacts the bottom surface of the photovoltaic laminate 40. For example, the entire support surface 51 may contact the bottom surface of the photovoltaic laminate 40.

[0051] In the embodiment of this application, Figure 1 and Figure 2 The first sub-frame 20 includes a base 21, a vertical wall 22, and a transverse wall 23. The transverse wall 23 is spaced apart from the base 21. The ends of the vertical wall 22 are connected to the transverse wall 23 and the base 21 respectively. The transverse wall 23, the vertical wall 22, and the base 21 collectively define a mounting slot 24.

[0052] The mounting slots 24 of the two first sub-frames 20 are arranged oppositely to accommodate a set of opposing edges of the photovoltaic laminate 40. The surfaces of the bases 21 of the two first sub-frames 20 that face the corresponding transverse walls 23 lie coplanar with the support surface 51. This allows the support surface 51 to be flat and, in conjunction with the surfaces of the bases 21 of the two first sub-frames 20 that face the corresponding transverse walls 23, support the bottom side of the photovoltaic laminate 40.

[0053] Of course, being in the same plane means being roughly coplanar, and a certain range of error and angle is allowed. In this way, the surfaces of the bases 21 of the two first sub-frames 20 facing the corresponding transverse walls 23 can cooperate with the supporting surface 51 to better support the photovoltaic laminate 40. Figure 1 In the embodiment, the upper surface of the substrate 21 and the supporting surface 51 are both surfaces supporting the photovoltaic laminate 40 , and both are in contact with the bottom surface of the photovoltaic laminate 40 .

[0054] In the embodiment of this application, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The support member 50 includes a support section 52 and first mounting portions 53 provided at both ends of the support section 52 . The support surface 51 is provided on the support section 52 .

[0055] The two first sub-frames 20 are provided with a second mounting portion 25 on one side thereof facing each other. In a specific implementation, the two second mounting portions 25 can be connected to the base 21. The first mounting portions 53 provided at the two ends of the support section 52 are connected to the second mounting portions 25 of the two first sub-frames 20, respectively.

[0056] The first mounting portions 53 at both ends of the support segment 52 are respectively connected to a second mounting portion 25 , so that the support segment 52 and the support surface 51 can be erected between the two substrates 21 , so that the support surface 51 can support the photovoltaic laminate 40 .

[0057] In the embodiment of the present application, the second mounting portion 25 includes two spaced apart positioning plates 250 , which are cantileveredly connected to the first sub-frame 20 , such as the base 21 of the first sub-frame, and the two positioning plates 250 jointly define a slot 251 .

[0058] The slots 251 of the two first sub-frames 20 are arranged opposite to each other so as to allow the first mounting portions 53 at the two ends of the supporting section 52 to be inserted and connected.

[0059] With this arrangement, the connection between the support member 50 and the first sub-frame 20 can be completed by simply inserting the two first mounting portions 53 into the corresponding slots 251 . This connection method is relatively simple and convenient for installation.

[0060] In the embodiment of the present application, the photovoltaic module frame 100 further includes a fastener 60 . The two positioning plates 250 are arranged vertically along a first direction F, which is the height direction of the first sub-frame 20 and the thickness direction of the photovoltaic laminate 40 .

[0061] The fastener 60 penetrates and connects the first mounting portion 53 and the two corresponding positioning plates 250 to securely connect the first mounting portion 53 to the corresponding slots 251 .

[0062] The fastener 60 passes through a positioning plate 250, a first mounting portion 53, and another positioning plate 250 in sequence to connect the first mounting portion 53 and the two positioning plates 250. The fastener 60 must occupy part of the installation space in the first direction F. By locating the two positioning plates 250 between the two ends of the base 21 along the first direction F, a certain amount of space can be reserved on both sides of the positioning plate 250 along the first direction F to accommodate the part of the fastener 60 that passes through the positioning plate 250 and the first mounting portion 53.

[0063] Reference Figure 6 、 Figure 7 In another possible embodiment, the positioning plate 250 located on the upper side contacts the bottom surface of the photovoltaic laminate 40 to support the photovoltaic laminate 40. In this configuration, the portion of the photovoltaic laminate 40 located between the two first sub-frames 20 can be well supported by the support member 50.

[0064] Furthermore, the distance between the two positioning plates 250 is equal to the thickness of the first mounting portion 25, so that the first mounting portion 25 is snapped into the slot 251 defined by the two positioning plates 250. In this way, the connection between the first mounting portion 25 and the second mounting portion 25 is relatively simple.

[0065] In the present application, refer to Figure 2 The two positioning plates 250 extend along the length direction R of the first sub-frame 20. Exemplarily, the length direction R is perpendicular to the first direction F.

[0066] In this configuration, the support member 50 can be connected to any position of the first sub-frame 20 along the length direction R as needed. Of course, the two positioning plates 250 can be integrally formed with the base 21 .

[0067] In the embodiment of the present application, there may be multiple support members 50 , and the multiple support members 50 are arranged at intervals along the length direction R of the first sub-frame 20 .

[0068] With such an arrangement, when the length of the first sub-frame 20 is longer, that is, when the edge length of the photovoltaic laminate 40 corresponding to the first sub-frame 20 is longer, several more support members 50 can be arranged in the length direction R of the first sub-frame 20 to prevent the photovoltaic laminate 40 from being damaged due to depression or the like in this direction.

[0069] In the present application, continue to refer to Figure 4 The supporting section 52 includes a bottom wall 521 , two side walls 522 and two top walls 523 .

[0070] The two side walls 522 are connected to opposite sides of the bottom wall 521. A top wall 523 is connected to each end of the side walls 522 facing away from the bottom wall 521. The two top walls 523 are spaced apart from each other, and the surfaces of the two top walls 523 facing away from the bottom wall 521 jointly define the support surface 51. The first mounting portion 53 is constructed as a plate-like member integrally formed with the bottom wall 521. This allows the support member 50 to be constructed as a hollow component, which is lightweight and also facilitates processing and forming. The support member 50 can be made of ordinary channel steel, and the first mounting portion 53 can be formed by cutting away the side walls 522 and top wall 523 at both ends.

[0071] In the present application, continue to refer to Figure 5 The photovoltaic module frame 100 further includes two oppositely disposed second sub-frames 30, and the length of the first sub-frame 20 is greater than the length of the second sub-frame 30. The two first sub-frames 20 and the two second sub-frames 30 are alternately arranged and connected to each other to form the photovoltaic module frame 100.

[0072] Since the length of the first sub-frame 20 is greater than that of the second sub-frame 30, the extension direction of the first sub-frame 20 can correspond to the length direction R of the photovoltaic laminate 40, and the extension direction of the second sub-frame 30 can correspond to the width direction of the photovoltaic laminate 40. Of course, the opposing side surfaces of the two second sub-frames 30 can also be provided with mounting grooves for mounting the other two opposing edges of the photovoltaic laminate 40.

[0073] In this application, the photovoltaic module frame 100 is described as a square frame as an example. In practice, the shape of the photovoltaic module frame 100 can be flexibly set according to the shape of the photovoltaic laminate 40.

[0074] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
