[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the utility model, not all the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0027] With the promotion of clean energy - solar energy, more and more life scenes have been added with solar power generation functions. For example, photovoltaic modules are laid on the roof of a car or roof. When the sunlight shines vertically on the photovoltaic module, the light-receiving area of ​​the photovoltaic module is the largest, and the power generation efficiency can reach the maximum value.

[0028] However, during the long-term use of photovoltaic modules, hail, tree branches, cleaning, maintenance and other processes may cause damage to the photovoltaic modules. For example, in extremely cold weather, the cover of the photovoltaic module may be damaged by hail, and tree branches falling on the cover may pierce the cover. The existing photovoltaic modules are an integrated product, and both surface damage and hidden cracks in the battery cells cannot be repaired. The entire product needs to be replaced, and the maintenance and replacement costs are high.

[0029] Based on the above questions, please refer to Figure 1 The embodiment of the present application provides a photovoltaic module 1, which may include: a laminate 10 and a cover plate 20. The cover plate 20 may be arranged on the surface of the laminate 10 to protect the laminate 10. The laminate 10 may be used to receive sunlight and convert solar energy into electrical energy, and then store the electrical energy.

[0030] The laminate 10 may include a front plate 110, a back plate 120, and a battery cell 130. The front plate 110 may be used to protect the battery cell 130, and the back plate 120 may be used to support the battery cell 130. The battery cell 130 may be disposed between the front plate 110 and the back plate 120. The front plate 110 may have a first surface 112 and a second surface 113 opposite to each other, and the battery cell 130 may be specifically disposed on the first surface 112.

[0031] The embodiments of the present application do not limit the specific arrangement of the battery cell 130. For example, it can be adhesive, or an embedding groove can be opened on the first surface 112 to embed the battery cell 130 into the first surface 112, and the battery cell 130 and the first surface 112 can be interference-connected, etc. There is no limitation here, and the specific arrangement can be based on actual conditions.

[0032] It should be noted that the embodiment of the present application does not limit the number of battery cells 130. The battery cell 130 can be set to one piece or multiple pieces. When the battery cell 130 is set to multiple pieces, the multiple battery cells 130 can be connected in series through wires, which can increase the overall voltage and provide greater output power to the outside. It can be understood that the multiple battery cells 130 can also be connected in parallel through wires to increase the overall capacity. The specific way of connecting the multiple battery cells 130 can be set according to actual conditions and is not limited here.

[0033] In this embodiment, the battery cell 130 can be connected to the first surface 112 through an adhesive film. It should be noted that the adhesive film is a hot melt adhesive, that is, at room temperature, the adhesive film is solid and has no stickiness. When the adhesive film is heated to a certain temperature, the adhesive film will melt and adhere to the object in contact with it.

[0034] Specifically, the adhesive film can be a thermoplastic or thermosetting material, such as polyvinyl chloride, polyethylene, polypropylene, polyamide, polyester, polycarbonate, etc. These materials soften and flow when heated, but become hard and elastic after cooling, which is beneficial to improve the structural strength and stability of the photovoltaic module 1.

[0035] In this embodiment, the front plate 110 and the battery cell 130 may also be connected by an adhesive film, and the back plate 120 and the battery cell 130 may also be connected by an adhesive film.

[0036] Furthermore, in this embodiment, the front plate 110 can be made of a polymer transparent or composite transparent material, such as polyvinyl fluoride, polyvinylidene fluoride, ethylene-tetrafluoroethylene copolymer, or a composite material thereof with polyethylene terephthalate, polycarbonate, etc. These materials have good heat resistance, good chemical corrosion resistance, good wear resistance, and good electrical insulation performance.

[0037] The back plate 120 may be made of a rigid material, such as metal, composite fiber or plastic, and specifically, aluminum, copper, carbon fiber, glass fiber, aramid fiber, polyvinyl chloride, polyethylene, polypropylene, polyamide, polyester, polycarbonate, etc. These materials are wear-resistant and waterproof, and have a certain support function and rigidity, and can support the laminate 10 to be flat or non-flat.

[0038] Specifically, in this embodiment, the front plate 110, the battery cell 130 and the back plate 120 can be laminated into an integrated structure by vacuum heating, which can further improve the overall stability of the laminate 10. When the photovoltaic module 1 is set in the wild or in a harsh environment, the front plate 110 and the back plate 120 can effectively protect the battery cell 130 to prevent the battery cell 130 from being damaged, thereby maintaining the normal use of the photovoltaic module 1.

[0039] The cover plate 20 may be disposed on the front plate 110 and cover the front plate 110 and the battery cell 130. Specifically, the cover plate 20 may be disposed on the front plate 110 and cover the battery cell 130 to protect the battery cell 130.

[0040] In this embodiment, the cover 20 can be made of a light-transmitting material, preferably a material with high transmittance, to increase the transmittance of sunlight, thereby increasing the absorption of sunlight by the battery cells 130 in the laminate 10. It should be noted that the embodiment of the present application does not limit the color of the light-transmitting material. Light-transmitting materials of different colors can be selected for different application scenarios or user needs. For example, when used in the snow, white light-transmitting material can be used to meet the differentiated needs of users and scenarios.

[0041] Specifically, the cover plate 20 can be made of materials such as polycarbonate or polyethylene terephthalate, etc. These materials have the characteristics of high transparency, good thermal conductivity, good chemical corrosion resistance and good wear resistance, and can fully transmit sunlight while also protecting the laminate 10.

[0042] In addition, in some embodiments, the surface of the cover plate 20 away from the laminate 10 can be set to a smooth surface. For example, the surface of the cover plate 20 away from the laminate 10 can be smoothed, frosted, coated, etc. to further meet the differentiated needs of users and scenarios.

[0043] It is understandable that in this embodiment, the thickness of the cover plate 20 can be 1mm-5mm, for example, the thickness of the cover plate 20 can be 1mm, 3mm or 5mm, etc. Preferably, the thickness of the cover plate 20 can be 3mm. If the thickness of the cover plate 20 is too thin, it may cause the cover plate 20 to be insufficient in strength and difficult to protect the laminate 10. If the thickness of the cover plate 20 is too thick, it may affect the light transmittance of the cover plate 20 and reduce the absorption efficiency of the laminate 10 to sunlight. It should be noted that the embodiment of the present application does not limit the specific thickness of the cover plate 20, and it can be set according to different application scenarios or user needs to meet the differentiated needs of users and scenarios.

[0044] In summary, the materials used to make the laminate 10 and the cover plate 20 are also light in weight, so that the photovoltaic module 1 can be applied to more occasions and flexibly installed in more scenes. In addition, the materials used to make the laminate 10 and the cover plate 20 do not contain glass. Compared with traditional photovoltaic modules, the photovoltaic module 1 provided in the embodiment of the present application can also avoid the risk of the laminate 10 and / or the cover plate 20 bursting and causing injuries to people.

[0045] In this embodiment, the cover plate 20 can be detachably connected to the laminate 10 , so that the cover plate 20 can be easily disassembled to inspect the laminate 10 , replace the battery cell 130 or replace the cover plate 20 .

[0046] The photovoltaic module 1 provided in the embodiment of the present application is provided with a laminate 10 and a cover plate 20, wherein the front plate 110 has a first surface 112 and a second surface 113 opposite to each other, and a battery cell 130 is provided on the first surface 112, and the cover plate 20 is provided on the front plate 110 to cover the battery cell 130 and the front plate 110, wherein the cover plate 20 is detachably connected to the laminate 10, specifically, the cover plate 20 is detachably connected to the front plate 110, when the cover plate 20 is damaged or the battery cell 130 is cracked, the cover plate 20 can be removed, and the cover plate 20 or the battery cell 130 can be repaired or replaced, so as to avoid the problem of excessive cost for overall replacement of the photovoltaic module 1 after partial damage.

[0047] It should be noted that the embodiment of the present application does not limit the connection method between the cover plate 20 and the laminate 10. For example, in one embodiment, the photovoltaic module 1 may also include a connector 30, and the cover plate 20 and the laminate 10 may be detachably connected through the connector 30.

[0048] Specifically, the front plate 110 may be provided with a first mounting hole 111 that passes through the first surface 112 and the second surface 113, and the front plate 110 may be provided with a second mounting hole 121 that corresponds to the first mounting hole 111. The cover plate 20 may be provided with a third mounting hole 210 that matches the first mounting hole 111. The inner surfaces of the first mounting hole 111, the second mounting hole 121, and the third mounting hole 210 may have internal threads, and the connector 30 may be a bolt that can be screwed into the first mounting hole 111, the second mounting hole 121, and the third mounting hole 210 to achieve the installation between the laminate 10 and the cover plate 20.

[0049] Furthermore, the connecting member 30 can also be a combination of bolts and nuts. After the bolts are screwed into the first mounting hole 111, the second mounting hole 121 and the third mounting hole 210, the nuts can be screwed into the bolts, which can further improve the overall stability of the photovoltaic component 1.

[0050] It should be noted that, in some embodiments, the inner surfaces of the first mounting hole 111, the second mounting hole 121 and the third mounting hole 210 may not be provided with internal threads. The inner surfaces of the first mounting hole 111, the second mounting hole 121 and the third mounting hole 210 may be set to a rough surface, and the outer surface of the connecting member 30 may also be set to a rough surface. The connecting member 30 may be interference connected with the first mounting hole 111, the second mounting hole 121 and the third mounting hole 210, which can simplify the installation between the laminate 10 and the cover plate 20.

[0051] It should be noted that the present application does not limit the opening positions of the first mounting hole 111 and the second mounting hole 121. For example, in other embodiments, the first mounting hole 111 may be opened on the cover plate 20, and a second mounting hole 121 corresponding to the first mounting hole 111 may be opened on the front plate 110. The connector may be inserted through the first mounting hole 111 and the second mounting hole 121 and connect the cover plate 20 and the laminate 10. For example, in some other embodiments, the first mounting hole 111 may be opened on the cover plate 20, and a second mounting hole 121 corresponding to the first mounting hole 111 may be opened on the back plate 120. The connector may be inserted through the first mounting hole 111 and the second mounting hole 121 and connect the cover plate 20 and the laminate 10. The specific configuration may be made according to the actual situation, and no limitation is made here.

[0052] In addition, in some other embodiments, the laminate 10 and the cover plate 20 can also be snap-connected, for example, the laminate 10 can be provided with a buckle, and the cover plate 20 can be provided with a slot, and the laminate 10 and the cover plate 20 can be snap-connected through the buckle and the slot. It should be noted that the present application does not limit the specific structure and form of the buckle and the slot, which can be selected according to user needs and usage scenarios. In addition, in some embodiments, the buckle can also be provided on the cover plate 20, and the slot can also be provided on the laminate 10, which will not be repeated here.

[0053] Please refer again Figure 1 In one embodiment, the front plate 110 and the back plate 120 can be configured as a plane, and the cover plate 20 can be set as a plane that matches the front plate 110 and is attached to the front plate 110. For example, in one embodiment, the front plate 110 and the back plate 120 can be configured as continuous planes with the same curvature, so that they can be adapted to a flat position such as a bungalow roof or the ground. In addition, the front plate 110 and the back plate 120 can also be configured as a continuous serrated plane, so that they can be adapted to a traditional tile roof, so as to improve the adaptability of the photovoltaic module 1 to the external environment.

[0054] See also Figure 3 In another embodiment, the front panel 110 and the back panel 120 can also be configured as a curved surface, and the cover panel 20 can be configured as a curved surface that matches the front panel 110 and is attached to the front panel 110. For example, in one embodiment, the front panel 110 and / or the back panel 120 can be configured as a curved surface similar to a wave shape, so that it can be adapted to a traditional tile roof. Specifically, the curved surface structure of the back panel 120 can be embedded in the wave structure of a traditional tile roof, so that the stability of the photovoltaic module 1 when installed on the tile roof can be improved. In addition, the curved surface structure of the front panel 110 is similar to the tile structure, which is conducive to improving the aesthetics of the photovoltaic module 1 after it is installed on the tile roof. In summary, the photovoltaic module 1 provided in the embodiment of the present application can improve the adaptability of the photovoltaic module 1 to the external environment.

[0055] It should be noted that the embodiments of the present application do not limit the specific shapes and structures of the laminate 10 and the cover plate 20, which can be selected according to actual conditions. Preferably, the laminate 10 and the cover plate 20 can have the same or similar shape, size, curvature, etc., which can improve the overall stability of the photovoltaic module 1 and avoid the situation where the structures of the laminate 10 and the cover plate 20 are difficult to adapt and cause damage.

[0056] Please refer again Figure 3In one embodiment, the photovoltaic module 1 may further include a plurality of laminates 10, and the cover plate 20 is disposed on the front plate 110 of the plurality of laminates 10 and covers the plurality of laminates 10. That is, in this embodiment, a plurality of laminates 10 may be provided, and the plurality of laminates 10 share the same cover plate 20, thereby reducing the workload when installing the photovoltaic module 1. It should be noted that the embodiment of the present application does not limit the specific number of laminates 10, for example, it may be 4, 8, 20, etc., and may be specifically set according to actual conditions.

[0057] Furthermore, multiple laminates 10 can be arranged in an array, which can improve the overall aesthetics of the photovoltaic module 1. At the same time, when one of the laminates 10 fails, such an arrangement can also facilitate maintenance personnel to quickly find the fault point, which is conducive to improving the maintenance efficiency of the photovoltaic module 1. The embodiment of the present application also does not limit the array mode. For example, when the laminates 10 are set to 4, it can be set to a 2×2 array, when the laminates 10 are set to 8, it can be set to a 2×4 array, and when the laminates 10 are set to 20, it can be set to a 4×5 array. It can be set according to actual conditions. In addition, multiple laminates 10 can also be set separately, which can further facilitate maintenance personnel to repair and replace damaged laminates 10. In addition, according to the shape of the array, in addition to being arranged in the above-mentioned rectangular plane array, multiple laminates 10 can also be arranged in a circular plane array. According to the array type, in addition to being arranged in the above-mentioned solid plane array, multiple laminates 10 can also be arranged in a hollow plane array, etc., which can be set according to actual conditions.

[0058] The photovoltaic module 1 provided in the embodiment of the present application is provided with a laminate 10 and a cover plate 20, wherein the front plate 110 has a first surface 112 and a second surface 113 opposite to each other, and a battery cell 130 is provided on the first surface 112, and the cover plate 20 is provided on the front plate 110 to cover the battery cell 130 and the front plate 110, wherein the cover plate 20 and the front plate 110 are detachably connected, and when the cover plate 20 is damaged or the battery cell 130 is cracked, the cover plate 20 can be removed, and the cover plate 20 or the battery cell 130 can be repaired or replaced, so as to avoid the problem of excessive cost for overall replacement of the photovoltaic module 1 after partial damage.
