[0040] Specifically, the photovoltaic module frame provided by the present application comprises long frames and short frames, wherein the long frames are used for being mounted on the long edge of the photovoltaic laminate, and the short frames are used for being mounted on the short edge of the photovoltaic laminate. The number of the long frames in the photovoltaic module frame corresponds to the number of the long edges of the photovoltaic laminate, and the number of the short frames in the photovoltaic module frame corresponds to the number of the short edges of the photovoltaic laminate. In the present embodiment, the number of the long frames and the number of the short frames are both two. In addition, it should be noted that the present application does not make any limitation on the photovoltaic laminate, and the typical photovoltaic laminate comprises, from top to bottom, a transparent cover plate, a first adhesive film layer, a solar cell array, a second adhesive film layer and a back plate.

[0041] As shown in the figure, in the present embodiment, each long frame and each short frame comprises a side plate 101, a top plate 100, a first bending part 103 and a bottom plate 102. The side plate 101 comprises an upper edge and a lower edge, wherein the upper edge comprises at least one notch 101'. The top plate 100 is connected perpendicularly to the side plate 101 through the non-notched part in the upper edge of the side plate 101 and extends to one side (hereinafter referred to as the first side) of the side plate 101. The number of the first bending parts 103 is the same as the number of the notches in the upper edge of the side plate 101 and corresponds to the notches one by one, and each first bending part 103 is arranged at the notch 101' corresponding to the upper edge of the side plate 101. Each first bending part 103 comprises at least a first horizontal plate 1031 and a first vertical plate 1032, wherein the first horizontal plate 1031 is connected perpendicularly to the side plate 101 through the notched part in the upper edge of the side plate 101 and extends to the first side of the side plate 101, and the first vertical plate 1032 is connected perpendicularly to the first horizontal plate 1031 through the edge of the side plate 101 away from the first horizontal plate 1031 and extends downward, wherein the width (L1) of the first horizontal plate 1031 is less than the width of the top plate 100, and the width (L2) of the first vertical plate 1032 is less than the width of the top plate 100. Figure 5 Figure 5 ​The length of the side plate 101 in the first direction is less than the width of the side plate 101. It should be noted that the direction in which the long (short) frame extends is defined as the first direction. Based on this, for any one of the top plate 100, the side plate 101, the bottom plate 102, the first horizontal plate 1031 and the first vertical plate 1032, the distance of the plate in the first direction is defined as the length of the plate. Correspondingly, for any one of the top plate 100, the side plate 101, the bottom plate 102, the first horizontal plate 1031 and the first vertical plate 1032, the direction perpendicular to the first direction in the plane in which the plate is located is defined as the second direction, and the distance of the plate in the second direction is defined as the width of the plate. The bottom plate 102 is connected to the side plate 101 perpendicularly through the lower edge of the side plate 101 and extends to the first side of the side plate 101, that is, the bottom plate 101 is located on the same side of the side plate 100 as the top plate 100 and the first bending part 103. It should be noted that (1) in the embodiment, the notch 101' of the upper edge of the side plate 101 is rectangular. Those skilled in the art can understand that the shape of the notch 101' of the upper edge of the side plate 101 should not be limited to the above-mentioned rectangle, and in other embodiments, the notch 101' can also be, for example, an inverted trapezoid, etc., as long as the notch can extend the first horizontal plate 1031. The shape of the notch 101' is suitable for the utility model, and for the sake of simplicity, all possible shapes of the notch 101' are not listed here. (2) In the embodiment, the length of the top plate 100, the side plate 101 and the bottom plate 102 in the long frame is related to the length of the photovoltaic laminate, and the length of the top plate 100, the side plate 101 and the bottom plate 102 in the short frame is related to the width of the photovoltaic laminate, which is not limited here. (3) For the long frame and the short frame, the width of the top plate 100 in the embodiment is 6mm to 8mm, the width of the side plate 101 is related to the thickness of the photovoltaic laminate, and in general, the width of the side plate 101 is 5.5mm to 6.5mm, the width of the bottom plate 102 is 12mm to 14mm, the length of the first horizontal plate 1031 and the first vertical plate 1032 is the same, and the length of the first horizontal plate 1031 and the first vertical plate 1032 is 59mm to 61mm, the width of the first horizontal plate 1031 is 2.4mm to 2.8mm, and the width of the first vertical plate 1032 is 1.1mm to 1.5mm. Those skilled in the art can understand that the above is only a preferred embodiment, which should not be a limitation on the size of the above plates, and the length or width of the above plates can be determined according to the actual design requirements, and for the sake of simplicity, all possible lengths and widths of the plates are not listed here.

[0042] The top plate 100, the side plate 101 and the bottom plate 102 enclose a receiving groove which matches the edge of the photovoltaic laminate. During assembly, the long edge of the photovoltaic laminate 200 is installed into the receiving groove of the long side frame, and the short edge of the photovoltaic laminate 200 is installed into the receiving groove of the short side frame, thereby completing the installation of the photovoltaic module frame. An adhesive such as silicone is disposed between the edge of the photovoltaic laminate 200 (including the side surface, the upper surface edge region and the lower surface edge region of the photovoltaic laminate 200) and the photovoltaic module frame, so that the photovoltaic laminate 200 can be well fixed in the photovoltaic module frame. After the installation of the frame is completed, the side surface of the long (short) edge of the photovoltaic laminate 200 is in contact with the first vertical plate 1032 in the first bending part 103 of the long (short) side frame. In addition, since the first bending part 103 is formed at the notch of the upper edge of the side plate 101, the upper surface of the first bending part 103 (i.e. the upper surface of the first horizontal plate 1031) is lower than the upper surface of the top plate 100. In the embodiment, by reasonably designing the width of the notch 101' of the upper edge of the side plate 101, the upper surface of the first horizontal plate 1031 in the first bending part 103 is flush with the upper surface of the photovoltaic laminate 200 after the installation of the frame is completed. It can be understood by those skilled in the art that the upper surfaces of the first horizontal plate 1031 and the photovoltaic laminate 200 are flush if the height difference between the upper surfaces falls within the range of process error. It should be noted that (1) the definition of the width of the notch of the upper edge of the side plate 101 can refer to the definition of the width of the top plate 100, the side plate 101, the bottom plate 102, the first horizontal plate 1031 and the first vertical plate 1032 in the foregoing, and will not be described again for the sake of simplicity. (2) Considering that there is an adhesive layer between the upper surface edge region of the photovoltaic laminate 200 and the top plate 100 of the frame, the width of the notch 101' of the upper edge of the side plate 101 is designed such that there is a height difference between the upper surface of the first horizontal plate 1031 in the first bending part 103 and the lower surface of the top plate 100 after the first horizontal plate 1031 extends from the notch 101', and the height difference is equal to the thickness of the adhesive layer. If a small amount of adhesive is used between the upper surface edge region of the photovoltaic laminate 200 and the top plate 100 of the frame in order to prevent the adhesive from overflowing and affecting the light receiving area of the photovoltaic module, the thickness of the adhesive layer between the two can be negligible. In this case, the width of the notch 101' of the upper edge of the side plate 101 can be designed such that the upper surface of the first horizontal plate 1031 in the first bending part 103 is flush with the lower surface of the top plate 100 after the first horizontal plate 1031 extends from the notch 101'.

[0043] The photovoltaic module frame provided by the utility model forms the water / dust discharging port at the first bending part of the photovoltaic module frame, so that after the photovoltaic module frame provided by the utility model is installed to the edge of the photovoltaic laminate, the dust and water (such as rainwater) on the upper surface of the photovoltaic laminate can be discharged along the water / dust discharging port (i.e. the upper surface of the first bending part) in time. Especially when the upper surfaces of the first bending part in the photovoltaic module frame and the photovoltaic laminate are flush, the water and dust discharging effect is particularly good. By using the photovoltaic module frame provided by the utility model, the water and dust on the upper surface of the photovoltaic laminate (especially the area of the upper surface of the photovoltaic laminate located at the edge of the frame) can be effectively prevented, so that the influence of the water and dust on the light collecting area of the photovoltaic module is effectively avoided, and the long-term power generation of the photovoltaic module is improved.

[0044] It should be noted that, Figure 2 The upper edge of the side plate of each long frame and each short frame in the photovoltaic module frame is provided with a notch, that is, the water / dust discharging port is formed on each edge of the photovoltaic module frame. Since the water / dust discharging port is formed on each edge of the photovoltaic module frame, the photovoltaic module frame can be installed in any way with one edge downward. The water / dust discharging port is formed on each edge of the photovoltaic module frame, which is a preferred embodiment and should not be a limitation of the present application. Those skilled in the art can understand that at least one edge of the photovoltaic module frame forms the water / dust discharging port to achieve the effect of water and dust discharging. For the case that only part of the edges of the photovoltaic module frame form the water / dust discharging port, when the photovoltaic module is installed, only the edge of the photovoltaic module frame forming the water / dust discharging port needs to be installed downward.

[0045] Preferably, as Figure 2As shown, the side plate in each long frame and each short frame of the photovoltaic module frame provided by the utility model includes two notches, which are arranged at positions close to the two ends of the side plate. Correspondingly, each long frame and each short frame includes two first bending parts, which are respectively located at positions close to the two ends of the frame. After the subsequent photovoltaic module frame is installed to the edge of the photovoltaic laminate, a drainage / dust port is formed at each of the two end positions of each edge of the photovoltaic module, wherein the drainage / dust port is formed at the two end positions of each edge of the photovoltaic module, which can effectively realize drainage and dust removal whether the photovoltaic module is installed horizontally or vertically, and is also beneficial to maximum gathering of water flow and dust to improve the effect of drainage and dust removal. Those skilled in the art can understand that the above is only a preferred embodiment, which should not be a limitation on the number and arrangement position of the notches on the side plate. In other embodiments, the number and arrangement position of the notches can be determined according to the actual design requirements. For the sake of simplicity, all possible numbers and possible arrangement positions of the notches are not listed here.

[0046] Preferably, as Figure 5 shown, the first bending part 103 in each long frame (and each short frame) of the photovoltaic module frame provided by the utility model further includes a first inclined plate 1033 in addition to the first horizontal plate 1031 and the first vertical plate 1032, which is connected with the first vertical plate 103 by the edge of the first vertical plate 1032 away from the first horizontal plate 1031 and is bent towards the direction of the side plate 101. More preferably, as Figure 5 shown, the first inclined plate 1033 is bent towards the direction of the side plate 101 to contact the side plate 101. The arrangement of the first inclined plate 1033 can effectively strengthen the strength of the first bending part 103, and also provide a glue contact space for the adhesive between the photovoltaic laminate and the frame. In this embodiment, the length of the first inclined plate 1033 is the same as the length of the first vertical plate 1032, and the angle between the first inclined plate 1033 and the first vertical plate 1032 (represented by α) is in the range of 144° to 146°. For the definition of the length of the first inclined plate 1033, please refer to the definition of the length of the top plate 100, the side plate 101, the bottom plate 102, the first horizontal plate 1031 and the first vertical plate 1032 in the foregoing, which will not be repeated here for the sake of simplicity. Figure 5

[0047] Preferably, the photovoltaic module frame provided by the utility model further includes a glue overflow prevention part in each long frame (and each short frame), which is a structure formed on the edge of the bottom plate 102 away from the side plate 101 and protruding upwards. More preferably, as Figure 5 and Figure 6 ​As shown, the protruding structure is a second bent portion 104 that bends towards the side plate 101. In this embodiment, the second bent portion 104 includes a second vertical plate 1041, a second horizontal plate 1042, and a second inclined plate 1043. The second vertical plate 1041 is perpendicularly connected to the bottom plate 102 via the edge of the bottom plate 102 away from the side plate 101 and extends upward. The second horizontal plate 1042 is perpendicularly connected to the second vertical plate 1041 via the edge of the second vertical plate 1041 away from the bottom plate 102 and extends towards the side plate 101. The second inclined plate 1043 is connected to the second horizontal plate 1042 via the edge of the second horizontal plate 1042 away from the second vertical plate 1041 and bends towards the bottom plate 102. Preferably, as shown... Figure 5 and Figure 6 As shown, the second inclined plate 1043 is bent towards the base plate 102 until it contacts the base plate 102. In this embodiment, the lengths of the second vertical plate 1041, the second horizontal plate 1042, and the second inclined plate 1043 are the same as the length of the base plate 103. The width of the second vertical plate 1041 ranges from 2.4mm to 2.8mm, the width of the second horizontal plate 1042 ranges from 1.1mm to 1.5mm, and the angle between the second inclined plate 1043 and the second horizontal plate 1042 is (…). Figure 5 The angle range (denoted by β) is 144° to 146°. The definitions of the length and width of the second vertical plate 1041 and the second horizontal plate 1042 can be found in the previous definitions of the length and width of the top plate 100, side plate 101, bottom plate 102, first horizontal plate 1031, and first vertical plate 1032. The definition of the length of the second inclined plate 1043 can be found in the previous definition of the length of the first inclined plate 1033. For simplicity, these definitions will not be repeated here. To ensure proper fixation, a certain amount of adhesive is used between the side plate 101 and the bottom plate 102 of the photovoltaic module frame and the photovoltaic laminate. An anti-overflow adhesive section is provided at the edge of the bottom plate 102 of the photovoltaic module frame to prevent adhesive overflow during frame installation.

[0048] Preferably, the photovoltaic module frame is made of stainless steel. On the one hand, compared with the commonly used material of the existing photovoltaic module, aluminum alloy profile, stainless steel has the characteristics of light weight, thus being conducive to reducing the weight of the photovoltaic module frame, and further being conducive to reducing the weight of the photovoltaic module as a whole, and being conducive to the light weight of the photovoltaic module. On the other hand, since stainless steel is easy to bend, the photovoltaic module frame provided by the utility model can be formed by bending. Compared with the way of forming the photovoltaic module frame by injection molding of aluminum alloy profile, it is obvious that the way of forming the photovoltaic module frame by bending stainless steel can not only simplify the manufacturing process of the frame but also reduce the production cost of the frame. Those skilled in the art can understand that the above-mentioned stainless steel is only a preferred embodiment, and should not be a limitation on the material of the photovoltaic module frame. Any material suitable for the photovoltaic module frame is suitable for the utility model. In order to be simple, all possible materials of the photovoltaic module frame are not listed here.

[0049] Correspondingly, the utility model also provides a kind of photovoltaic module, and the photovoltaic module includes the aforementioned photovoltaic module frame and the photovoltaic laminate installed in the photovoltaic module frame. In order to be simple, the aforementioned photovoltaic module is not repeated here, and its specific structure can refer to the content of the corresponding part in the foregoing. The photovoltaic module provided by the utility model has the characteristics of preventing water accumulation and dust accumulation and long-term power generation. Among them, for the case that the photovoltaic module frame includes the overflow glue prevention part, the photovoltaic module provided by the utility model further has the characteristics of preventing overflow glue; for the case that the photovoltaic module frame is made of stainless steel, the photovoltaic module provided by the utility model further has the characteristics of light weight, simple process and low cost.

[0050] In a preferred embodiment, the photovoltaic laminate comprises, from top to bottom, a transparent cover plate, a first encapsulating film, a solar cell array, a second encapsulating film, and a backsheet. The transparent cover plate comprises, from top to bottom, a resin fiberglass layer and a UV-resistant adhesive layer; the first encapsulating film comprises, from top to bottom, a first SGP (SentryGlasPlus) film layer and a first EVA (Ethylene Vinyl Acetate Copolymer) film layer; and the second encapsulating film comprises, from top to bottom, a second EVA film layer and a second SGP film layer. It should be noted that the structure of the solar cell array can be customized according to actual design requirements, and the backsheet can be implemented using existing conventional backsheets; this invention does not impose any limitations on this. Since the resin fiberglass layer is beneficial to improving the washability of the photovoltaic laminate surface, the UV-resistant adhesive layer is beneficial to improving the UV protection performance of the photovoltaic laminate, and the combination of the SGP film layer and the EVA film layer is beneficial to improving the elastic modulus and impact resistance of the photovoltaic laminate, the photovoltaic module provided by this utility model has the characteristics of being washable, UV resistant, and highly impact resistant.

[0051] It should be noted that a typical existing photovoltaic (PV) laminate, from top to bottom, includes ultra-clear glass, a first encapsulating film, a solar cell array, a second encapsulating film, and an encapsulation backsheet. Due to the high density of ultra-clear glass, the overall weight of the PV module is relatively large, failing to meet the load-bearing requirements of current distributed application scenarios. Currently, the main method to reduce the weight of PV modules is to thin the ultra-clear glass; however, this method reduces the mechanical strength of the PV module, severely affecting its impact resistance, making the surface of the PV module easily damaged by hard objects (such as hail). The PV module provided by this invention, when its frame is made of stainless steel and the PV laminate adopts the structure of the preferred embodiment described above, not only has the basic effects of preventing water and dust accumulation but also possesses the characteristics of being lightweight and having excellent impact resistance, effectively overcoming the shortcomings of existing PV modules that cannot balance weight and impact resistance.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be encompassed within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims. Furthermore, it is clear that the word "comprising" does not exclude other components, units, or steps, and the singular does not exclude the plural. Multiple components, units, or devices recited in the system claims may also be implemented by a single component, unit, or device through software or hardware.

[0053] The above-disclosed embodiments are merely some preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
