[0038] Next, referring to the drawings, the photovoltaic module 100 according to the embodiments of the present application is described.

[0039] As shown in Figures 1-4 According to the embodiments of the present application, the photovoltaic module 100 includes a housing 1 and a battery assembly 2, the housing 1 is formed with a receiving cavity 14, and the housing 1 is provided with a light-transmitting structure; the battery assembly 2 is installed in the receiving cavity 14, and the battery assembly 2 is rotatably connected with the housing 1 to adjust the relative position of the battery assembly 2 and the light-transmitting structure.

[0040] Thus, the difficulty of adjusting the photovoltaic assembly 100 can be reduced, the stability of the adjustment process can be improved, and the photovoltaic assembly 100 can be easily installed, thereby improving the practicality of the photovoltaic assembly 100.

[0041] First, refer to Figures 1-3 As shown, photovoltaic module 100 includes a housing 1 and a battery assembly 2. A housing 1 defines a receiving cavity 14, and a sidewall of the housing 1 is provided with a light-transmitting structure. The light-transmitting structure can be made of a transparent material, such as glass, to allow sunlight to pass through the light-transmitting structure and illuminate the receiving cavity 14. For example, the light-transmitting structure can be provided on the upper sidewall of the housing 1; alternatively, the light-transmitting structure can be provided on the right sidewall of the housing 1, although this is not a limitation of the present invention.

[0042] The battery assembly 2 is mounted within the housing 14 and is configured to generate electricity under sunlight. The battery assembly 2 is rotatably connected to the housing 1. The relative position of the battery assembly 2 and the light-transmitting structure can be adjusted by rotating the battery assembly 2 so that sunlight entering through the light-transmitting structure can better illuminate the battery assembly 2.

[0043] It is understood that by allowing the battery assembly 2 to rotate relative to the housing 1 to adjust the relative position of the battery assembly 2 and the light-transmitting structure, the adjustment is less difficult and more stable than adjusting the entire photovoltaic assembly 100. In addition, since the photovoltaic assembly 100 does not need to rotate, the photovoltaic assembly 100 can be directly installed on a fixed surface rather than on an adjustment device, which helps to reduce the difficulty of installing the photovoltaic assembly 100.

[0044] According to the photovoltaic assembly 100 of the embodiment of the present invention, the battery assembly can be driven to rotate relative to the shell 1 to achieve convenient adjustment of the battery assembly, which is beneficial to reducing the adjustment difficulty of the photovoltaic assembly 100, improving the stability of the adjustment process, and making the photovoltaic assembly 10 easy to install, thereby improving the practicality of the photovoltaic assembly 100.

[0045] In some embodiments of the present invention, the battery assembly 2 includes a battery supporting plate 21 and a first battery cell 22. The battery supporting plate 21 is rotatably connected to the shell 1, and the first battery cell 22 is installed on the battery supporting plate 21.

It should be noted that the first battery sheet 22 can be any one of a crystalline silicon solar cell, a gallium arsenide solar cell, various thin-film solar cells, a perovskite solar cell, and an organic solar cell, so that the first battery sheet 22 can generate electricity under sunlight irradiation.

[0047] The battery carrying plate 21 can be rotated relative to the shell 1 to drive the first battery sheet 22 to rotate, so as to adjust the relative positions of the first battery sheet 22 and the light-transmitting structure, such as making the extension direction of the first battery sheet 22 parallel to the light-transmitting structure or making the extension direction of the first battery sheet 22 intersect with the light-transmitting structure, so that the sunlight from the light-transmitting structure can better illuminate the first battery sheet 22.

[0048] Specifically, the first battery sheet 22 can be fixedly connected with the battery carrying plate 21 by sputtering, deposition, evaporation, coating, bonding or the like.

[0049] Through the above arrangement, the installation stability of the first battery sheet 22 can be improved, so as to ensure that the first battery sheet 22 can work better, and the reliability of the battery assembly 2 is improved.

[0050] Of course, the utility model is not limited to this, and the first battery sheet 22 can also be directly rotatably connected with the shell 1, so that the first battery sheet 22 can be rotated relative to the shell 1, thereby adjusting the relative positions of the first battery sheet 22 and the light-transmitting structure. Thus, the structure of the photovoltaic assembly 100 can be simplified.

Through the above arrangement, the plurality of battery assemblies 2 can generate electricity together, which is beneficial to improve the power generation efficiency of the photovoltaic assembly 100 and improve the practicability of the photovoltaic assembly 100.

[0052] In some embodiments of the utility model, as shown in Figure 1 At least a part of the battery assemblies 2 can be provided in linkage. Thus, a plurality of battery assemblies 2 can be adjusted at the same time through a single action, which is beneficial to reduce the adjustment difficulty of the photovoltaic assembly 100.

[0053] In some embodiments of the utility model, as shown in Figure 1As shown, the battery assembly 2 is multiple groups, multiple groups of battery assembly 2 is sequentially arranged along the first direction F1, and multiple battery assemblies 2 of each group are sequentially arranged along the second direction F2, and the first direction F1 and the second direction F2 are arranged intersectingly. Exemplarily, the first direction F1 can be set as Figure 1 As shown, the front and back direction, and the second direction F2 is set as Figure 2 As shown, the left and right direction.

[0054] Through the above setting, the space in the photovoltaic assembly 100 can be fully utilized, the power generation of the photovoltaic assembly 100 is improved, and the shape of the photovoltaic assembly 100 can be constructed to be more regular, such as rectangular, so that the photovoltaic assembly 100 is easy to arrange, and the practicability of the photovoltaic assembly 100 is improved.

Through the above setting, multiple battery carrying plates 21 of the same group can be adjusted synchronously, the adjustment difficulty of the photovoltaic assembly 100 is reduced, and the reliability of the photovoltaic assembly 100 is improved.

[0056] In some embodiments of the utility model, as Figure 4 As shown, multiple groups of battery assemblies 2 can be linked. Through the above setting, multiple battery carrying plates 21 can be adjusted synchronously, the adjustment difficulty of the photovoltaic assembly 100 is reduced, and the reliability of the photovoltaic assembly 100 is improved.

[0057] In some embodiments of the utility model, the battery assembly 2 is multiple, and each battery assembly 2 is correspondingly provided with a rotating shaft 3, and the rotating shaft 3 is rotatably supported on the shell 1.

[0058] For example, referring to Figure 1 As shown, the battery assembly 2 is multiple, and multiple battery assemblies 2 are arranged at intervals. Corresponding to each battery assembly 2, a rotating shaft 3 can be provided, the rotating shaft 3 is arranged extending along the second direction F2, and the two ends of the rotating shaft 3 along the length direction are respectively supported on the opposite side walls of the shell 1, so that the rotating shaft 3 can drive the battery assembly 2 to rotate around the rotating shaft 3, to adjust the relative position of the battery assembly 2 and the light-transmitting structure. Therefore, the adjustment of the battery assembly 2 is more stable and smooth, and the reliability of the photovoltaic assembly 100 is improved.

[0059] In some embodiments of the utility model, at least one end of at least one rotating shaft 3 extends out of the shell 1 to form a driving part. For example, referring to Figure 1As shown, at least one end of the rotating shaft 3 can be arranged to extend out of the shell 1 to form a driving portion, the driving portion being used to drive the rotating shaft 3 to rotate under the driving of an external force, and further drive the corresponding battery assembly 2 to rotate synchronously. It should be noted that the driving portion can be connected with a driving motor, so that the driving motor can drive the rotating shaft 3 to rotate through the driving portion.

[0060] Specifically, one end of the rotating shaft 3 along the length direction can be arranged to extend out of the shell 1 to form a driving portion; or both ends of the rotating shaft 3 along the length direction can be arranged to extend out of the shell 1 to form driving portions, and the utility model does not limit this.

[0061] It should be noted that one of the plurality of rotating shafts 3 can be connected with a driving motor, and the remaining rotating shafts 3 can be connected with the rotating shaft 3.

[0062] It can be understood that by arranging the driving portion outside the shell 1, the space occupation in the accommodating cavity 14 can be reduced, and the design rationality of the photovoltaic assembly 100 is improved.

[0063] In some embodiments of the utility model, each rotating shaft 3 is connected with a plurality of battery assemblies 2. For example, referring to Figure 1 As shown, a plurality of battery assemblies 2 can be arranged in sequence along the second direction F2, and the rotating shaft 3 is arranged to extend along the second direction F2 and connected with the plurality of battery assemblies 2 arranged in sequence along the second direction F2, so that the rotating shaft 3 can drive the plurality of battery assemblies 2 to rotate around the rotating shaft 3 at the same time. Thus, the structure of the photovoltaic assembly 100 can be simplified, and the processing difficulty of the photovoltaic assembly 100 is reduced.

[0064] In some embodiments of the utility model, as shown in Figure 1 As shown, a rotating sealing ring 6 can be arranged between the outer circumferential wall of the rotating shaft 3 and the shell 1. It should be noted that the material of the rotating sealing ring 6 can be any one of rubber, polytetrafluoroethylene and other elastic materials.

[0065] Through the above arrangement, the rotating sealing ring 6 is used to support the rotating shaft 3, so as to improve the rotating stability of the rotating shaft 3, and the rotating sealing ring 6 can also be used to seal the gap between the rotating shaft 3 and the shell 1, so as to avoid the leakage of the accommodating cavity 14, and the reliability of the photovoltaic assembly 100 is improved.

[0066] In some embodiments of the present invention, the photovoltaic assembly 100 of the embodiment of the present invention further includes: a linkage assembly 4, the linkage assembly 4 includes a first linkage member 41, a second linkage member 42 and a linkage line 43, the first linkage member 41 and the second linkage member 42 are respectively located at the two ends of the accommodating cavity 14 along the first direction F1 and are respectively rotatably connected to the shell 1, the linkage line 43 is connected between the first linkage member 41 and the second linkage member 42 and is linked to the multiple battery assemblies 2, and the linkage assembly 4 drives the multiple battery assemblies 2 to move synchronously through the linkage line 43.

[0067] For example, refer to Figure 4 As shown, the photovoltaic component 100 also includes a linkage component 4, which includes a first linkage member 41, a second linkage member 42 and a linkage line 43. The first linkage member 41 and the second linkage member 42 are respectively located at the two ends of the accommodating cavity 14 along the first direction F1, and the first linkage member 41 and the second linkage member 42 are respectively rotatably connected to the shell 1 so that the first linkage member 41 and the second linkage member 42 can rotate relative to the shell 1.

[0068] Among them, multiple battery assemblies 2 are arranged in sequence along the second direction F2, and a linkage line 43 is connected between the first linkage member 41 and the second linkage member 42. The linkage line 43 extends along the second direction F2, and the linkage line 43 is respectively linked to multiple battery assemblies 2 arranged in sequence along the second direction F2. When the first linkage member 41 and the second linkage member 42 rotate to drive the linkage line 43 to move, the linkage line 43 can drive multiple battery assemblies 2 to move synchronously.

[0069] Through the above-mentioned configuration, multiple battery assemblies 2 can be adjusted synchronously, which reduces the difficulty of adjusting the photovoltaic assembly 100 and improves the reliability of the photovoltaic assembly 100.

[0070] In some embodiments of the present invention, the first linkage member 41 and the second linkage member 42 both include a connecting shaft 44 and a plurality of rotating wheels 45 , and the plurality of rotating wheels 45 are arranged at intervals on the connecting shaft 44 . The relatively arranged rotating wheels 45 of the first linkage member 41 and the second linkage member 42 are provided with a linkage line 43 .

[0071] For example, refer to Figure 4 As shown, the first linkage member 41 and the second linkage member 42 both include a connecting shaft 44 and a plurality of rotating wheels 45. The plurality of rotating wheels 45 are axially spaced apart on the connecting shaft 44, and the plurality of rotating wheels 45 of the first linkage member 41 and the plurality of rotating wheels 45 of the second linkage member 42 are arranged one-to-one in the first direction F1.

[0073] Specifically, when the first linkage 41 and the second linkage 42 rotate clockwise, the linkage line 43 can drive the battery assembly 2 to rotate clockwise; when the first linkage 41 and the second linkage 42 rotate counterclockwise, the linkage line 43 can drive the battery assembly 2 to rotate counterclockwise. Therefore, the rotation stability of the battery assembly 2 can be improved, and the reliability of the photovoltaic module 100 can be improved.

[0074] Further, as shown in Figure 4 the first linkage 41 and the second linkage 42 can be provided with the rotation wheels 45 corresponding to the two sides of the battery assembly 2 in the second direction F2. Therefore, the linkage assembly 4 can drive the battery assembly 2 from both sides, and the rotation stability of the battery assembly 2 can be improved.

[0075] In some embodiments of the utility model, as shown in Figure 4 at least one end of the at least one connecting shaft 44 extends out of the shell 1 to form a driving part. It should be noted that the driving part can be connected with a driving motor, so that the driving motor can drive the driving shaft to rotate through the driving part.

[0076] Specifically, one end of the connecting shaft 44 in the length direction can extend out of the shell 1 to form the driving part, or both ends of the connecting shaft 44 in the length direction can extend out of the shell 1 to form the driving part, and the utility model does not limit this. Therefore, the operation stability of the linkage assembly 4 can be improved, and the reliability of the photovoltaic module 100 is improved.

[0077] In some embodiments of the utility model, as shown in Figure 4 one of the first linkage 41 and the second linkage 42 can be set as a driving part, and the other can be set as a driven part. Therefore, the structure of the photovoltaic module 100 can be simplified, and the operation reliability of the photovoltaic module 100 is improved.

[0078] In some embodiments of the utility model, as shown in Figure 4 a rotation sealing ring 6 can be arranged between the outer peripheral wall of the connecting shaft 44 and the shell 1. It should be noted that the material of the rotation sealing ring 6 can be any one of rubber, polytetrafluoroethylene and other elastic materials.

[0079] Through the above arrangement, the rotating sealing ring 6 is arranged to support the connecting shaft 44, so as to improve the rotating stability of the connecting shaft 44, and the rotating sealing ring 6 can also be arranged to seal the gap between the connecting shaft 44 and the shell 1, so as to avoid the leakage of the accommodating cavity 14, and the reliability of the photovoltaic module 100 is improved.

[0080] In some embodiments of the present application, the shell 1 comprises a first cover plate 11, a second cover plate 12 and a sealing assembly 13, the first cover plate 11 and the second cover plate 12 are arranged in parallel and spaced apart, and the edges of the two are sealed by the sealing assembly 13, and at least one of the first cover plate 11 and the second cover plate 12 is formed as a light-transmitting structure.

[0081] For example, as shown in Figure 2 , the shell 1 comprises a first cover plate 11, a second cover plate 12 and a sealing assembly 13, the first cover plate 11 and the second cover plate 12 are arranged in parallel and spaced apart along the third direction F3 (refer to the up-down direction shown in Figure 1 , the edges of the first cover plate 11 and the second cover plate 12 are sealed by the sealing assembly 13, so that the first cover plate 11, the second cover plate 12 and the sealing assembly 13 can jointly define the accommodating cavity 14.

[0082] Among them, the first cover plate 11 can be formed as a light-transmitting structure; or the second cover plate 12 can be formed as a light-transmitting structure; or the first cover plate 11 and the second cover plate 12 can be both formed as light-transmitting structures, which are not limited in the present application.

[0083] Exemplarily, the first cover plate 11 and the second cover plate 12 can be super white photovoltaic glass, so that the first cover plate 11 and the second cover plate 12 are both formed as light-transmitting structures.

[0084] Through the above arrangement, the forming difficulty of the shell 1 can be reduced, thereby reducing the processing difficulty of the photovoltaic module 100, and when the first cover plate 11 and the second cover plate 12 are both formed as light-transmitting structures, the light incidence angle of the photovoltaic module 100 can be increased, so as to increase the power generation of the photovoltaic module 100 to a certain extent, thereby improving the practicability of the photovoltaic module 100.

[0085] In some embodiments of the present application, as shown in Figure 2 , the sealing assembly 13 comprises: a first sealing member 131, the first sealing member 131 is clamped between the edge of the first cover plate 11 and the edge of the second cover plate 12 to seal the accommodating cavity 14. It should be noted that the material of the first sealing member 131 can be a waterproof sealing material containing butyl rubber. Thus, the space in the photovoltaic module 100 can be fully utilized, which is beneficial to reduce the overall size of the photovoltaic module 100, and the miniaturized design is realized.

[0086] In some embodiments of the present invention, the sealing assembly 13 includes a second sealing member 132, which covers the edges of the first cover plate 11 and the second cover plate 12 to seal the accommodating cavity 14. It should be noted that the material of the second sealing member 132 can be a waterproof sealing material containing butyl rubber or aluminum foil. This can reduce the difficulty of molding the photovoltaic module 100 and improve the practicality of the photovoltaic module 100.

[0087] In some embodiments of the present invention, the sealing assembly 13 includes a first sealing member 131 and a second sealing member 132. The first sealing member 131 is sandwiched between the edge of the first cover plate 11 and the edge of the second cover plate 12, and the second sealing member 132 is wrapped around the outer edges of the first cover plate 11 and the second cover plate 12. This arrangement allows for a double seal of the accommodating cavity 14, thereby improving the sealing performance of the photovoltaic module 100.
