Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a photovoltaic frame and a photovoltaic module. Background Technology

[0002] Photovoltaic cells typically employ a laminated structure composed of solar cells, encapsulant film, backsheet, and photovoltaic glass, combined with a photovoltaic frame. The laminated structure converts solar energy into electrical energy output, while the photovoltaic frame provides support and fixation. Existing photovoltaic module frames, such as... Figure 52 As shown, it can be basically divided into 4 surfaces: surface A, surface B, surface C, and surface D. The function of surface A is to limit the top of the laminate. Surfaces B and D are mainly used to ensure the rigidity of the frame and the overall strength of the component. The function of surface C is to prevent the frame from being twisted under force and to serve as the fastener installation and connection surface.

[0003] Currently, all four frames of existing photovoltaic modules have an A-side. After the photovoltaic module is installed, because the A-side of the photovoltaic frame is higher than the surface of the laminate, it will form an obstacle around the photovoltaic module, causing dust to accumulate at the edges, which seriously affects the power generation efficiency of the photovoltaic module. In addition, the long frame and short frame in the existing technology are connected by corner brackets. However, the existing frame lacks limited positioning of the corner brackets, which makes the corner brackets easy to fall off. Utility Model Content

Detailed Implementation

[0075] like Figure 52 As shown and in conjunction with the background technology, existing photovoltaic modules all have an A-side on all four sides of the frame. After installation, because the A-side of the photovoltaic frame protrudes above the surface of the laminate, it creates an obstruction around the photovoltaic module, causing dust to accumulate at the edges, severely affecting the power generation efficiency of the photovoltaic module. Furthermore, in the existing technology, the long and short frames are connected by corner brackets; however, the existing frame lacks limited restraint on the corner brackets, making them prone to falling off. To solve the above problems, this application provides a photovoltaic frame and a photovoltaic module.

[0085] The embodiments of this application will now be described in detail with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the embodiments of this application to facilitate a better understanding of the application.

[0086] See also Figures 1 to 51 As shown, this utility model provides a photovoltaic frame, which includes: two long frame 1s, configured to correspond one-to-one with the two long sides of the laminate 2, each long frame 1 including a slot 3 and a first bent portion connected to the slot 3, the long side of the laminate 2 being fitted into the slot 3; and two short frame 4s, configured to correspond one-to-one with the two short sides of the laminate 2, each short frame 4 including a support portion 5, a stop portion 6, and a second bent portion 7 having the same structure as the first bent portion, the support portion 5 and the stop portion 6 being set at an angle. The support 5 is used to support the laminate 2. The stop 6 extends away from the support 5 and stops the short side of the laminate 2. The height of the stop 6 is configured to be less than or equal to the thickness of the laminate 2. The second bend 7 is connected to the support 5. The second bend 7 includes a receiving cavity 701 for accommodating the corner bracket. The bottom of the second bend 7 is provided with a first hook 702 that is bent relative to the bottom wall of the second bend 7. The first hook 702 extends vertically or toward the side wall of the receiving cavity 701.

[0087] In this embodiment, the laminate 2 is rectangular, comprising two long sides and two short sides. These two long sides and two short sides are arranged alternately along the circumference of the laminate 2. The two long sides are positioned opposite each other along the width direction of the laminate 2, and the two short sides are positioned opposite each other along the length direction of the laminate 2. The two long frames 1 of the photovoltaic frame correspond one-to-one with the two long sides of the laminate 2. The long side of the laminate 2 is fitted into the corresponding slot 3 of the long frame 1. The slot 3 is filled with silicone 14, and the long side is bonded and fixed to the long frame through the silicone 14. That is, the long frame 1 of this application has an A-side, which ensures the bonding strength between the laminate 2 and the long frame 1, preventing the laminate from loosening. The first bend of the long frame 1 and the second bend 7 of the short frame 4 have the same structure. The second bend 7 includes a receiving cavity 701 for accommodating corner brackets. The bottom of the second bend 7 is provided with a first hook 702 that bends relative to the bottom wall of the second bend 7. The first bend also includes a receiving cavity for accommodating corner brackets. The bottom of the first bend is also provided with a first hook that bends relative to the bottom wall of the first bend. Adjacent long frames 1 and short frames 4 are connected by a corner bracket. That is, a corner bracket is provided at each of the four corners of the photovoltaic frame. For the long frame 1 and short frame 4 connected by the corner bracket, the part of the corner bracket is located in the receiving cavity of the long frame 1 and the part of the corner bracket is located in the receiving cavity of the short frame 4.

[0088] The two short frames 4 of the photovoltaic frame correspond one-to-one with the two short sides of the laminate 2. The short sides of the laminate 2 are supported by the corresponding support parts 5 of the short frames 4. The support parts 5 and the stop parts 6 are set at an angle. Silicone 14 is filled between the support parts 5, the stop parts 6 and the short sides to bond and fix the short sides to the short frames 4. The stop parts 6 can stop the side of the short side of the laminate 2 to limit the laminate 2 in the length direction. The height of the stop parts 6 is less than or equal to the thickness of the laminate 2. That is, the short frames 4 of this application have eliminated the A side compared with the prior art. The short frames 4 do not block the upper surface of the laminate 2, which allows water to flow smoothly. This prevents dirt on the surface of the laminate 2 from accumulating at the edge of the short frames 4 under the washing of natural rainwater, thereby improving the power generation efficiency of the photovoltaic module.

[0089] The receiving cavity 701 provides installation space for the corner bracket. At the same time, the setting of the receiving cavity 701 simplifies the installation process of the corner bracket, allowing the corner bracket to be easily slid into or embedded in the receiving cavity 701. The first hook 702 set at the bottom of the second bend 7 can effectively lock the corner bracket and effectively limit the corner bracket, preventing it from loosening or falling off due to external factors (such as wind force and temperature changes) during long-term use, thereby improving the structural stability of the photovoltaic frame.

[0090] Laminate 2 refers to a composite module in photovoltaic module manufacturing, which integrates multiple material layers through lamination technology. Specifically, photovoltaic laminates mainly include the following key components: a glass layer, which is the outermost transparent covering material of the photovoltaic laminate, used to protect the solar cells from the influence of the external environment; an EVA (ethylene-vinyl acetate copolymer) layer or a POE (polyolefin elastomer) layer, these encapsulation material layers are located between the glass and the solar cells, and between the solar cells and the backsheet, their function is to firmly adhere the solar cells between the upper and lower materials, while also providing waterproof, moisture-proof and cushioning functions to protect the solar cells from mechanical damage; a solar cell layer, composed of multiple silicon-based solar cells connected in series, used to convert solar radiation into electrical energy; and a backsheet layer, located at the bottom of the photovoltaic laminate, usually made of materials such as PET (polyester) film, fluoropolymer film, etc., which has excellent insulation and weather resistance, protecting the solar cells from the environmental damage behind them, and also serving as one of the encapsulation materials of the module, forming a complete encapsulation system together with the EVA or POE layer.

[0091] See also Figure 2 , Figures 12 to 50 As shown, in some embodiments of this application, the stop portion 6 includes a first vertical segment 61 extending in a vertical direction.

[0092] Specifically, the first vertical segment 61 can provide a stop and limit for the laminate in the length direction of the laminate.

[0093] See also Figure 13 , Figure 15 , Figure 18 , Figure 20 , Figure 22 , Figure 23 , Figure 25 , Figure 28 , Figure 30 As shown, in some embodiments of this application, the end of the first vertical segment 61 away from the support portion 5 is connected to a first horizontal segment 612, the first horizontal segment 612 extends from the first vertical segment 61 toward the side where the support portion 5 is located, and the height of the first horizontal segment 612 is configured to be less than or equal to the thickness of the laminate 2.

[0094] Specifically, the height of the first straight section 612 is configured to be less than or equal to the thickness of the laminate 2, that is, the upper surface of the first straight section 612 is flush with or lower than the upper surface of the laminate, so that dust or water will not accumulate on the short edge of the photovoltaic frame.

[0095] See also Figure 13 and Figure 22As shown, in some embodiments of this application, the end of the first straight segment 612 away from the first vertical segment 61 is bent toward the side where the support part 5 is located to form a first bent segment 613, and the angle between the first bent segment 613 and the first straight segment 612 is an acute angle or a right angle.

[0096] Specifically, after the laminate is placed on the support 5, the end of the first bending section 613 near the laminate abuts against the upper surface of the laminate. The first bending section 613 can stop the silicone 14 filled between the support 5, the first vertical section 61, the first straight section 612, the first bending section 613 and the laminate, preventing the silicone 14 from overflowing.

[0097] See also Figures 16 to 52 As shown, in some embodiments of this application, the second bending portion 7 is located at the bottom of the support portion 5. The second bending portion 7 also includes a second bending segment 703, a third bending segment 704, and a fourth bending segment 705 connected in sequence. The second bending segment 703 and the fourth bending segment 705 are located on the same side of the third bending segment 704. The third bending segment 704 extends in a vertical direction, and the fourth bending segment 705 extends in a first direction. The second bending segment 703, the third bending segment 704, and the fourth bending segment 705 together form an accommodating cavity 701 with an opening. The first hook 702 is provided at the end of the fourth bending segment 705 away from the third bending segment 704.

[0098] Specifically, the second bending portion 7 is formed by the second bending segment 703, the third bending segment 704, and the fourth bending segment 705. The multi-bending structure can effectively disperse external pressure, reduce stress concentration, and significantly improve the overall stability and deformation resistance of the short frame 4. The opening design of the receiving cavity 701 provides space and a way for the corner bracket to be embedded, while the first hook 702 ensures that the corner bracket remains stable within the receiving cavity 701.

[0099] See also Figure 17 , Figure 18 , Figure 19 , Figures 20 to 25 , Figures 31 to 35 As shown, in some embodiments of this application, the second bending segment 703 includes a U-shaped bending segment 7031 and a second straight segment 7032 extending along a first direction. The opening of the U-shaped bending segment 7031 faces the support portion 5. Along the first direction, one end of the U-shaped bending segment 7031 is connected to the support portion 5, and the other end of the U-shaped bending segment 7031 is connected to one end of the second straight segment 7032. The other end of the second straight segment 7032 is connected to the third bending segment 704, and the top surface of the second straight segment 7032 is in contact with the bottom surface of the support portion 5.

[0100] Specifically, the U-shaped bend 7031 further limits the corner bracket, ensuring its stability within the receiving cavity 701. Simultaneously, the U-shaped bend 7031 and the second straight section 7032 also provide support for the support portion 5.

[0101] See also Figures 21 to 25 , Figures 32 to 35 As shown, in some embodiments of this application, the second bending segment 703 includes a second vertical segment 7033, a third straight segment 7034, a first inclined segment 7035, and a fourth straight segment 7036. The second vertical segment 7033 extends in a vertical direction, while the third straight segment 7034 and the fourth straight segment 7036 both extend in a first direction. One end of the second vertical segment 7033 is connected to the end of the support portion 5 away from the stop portion 6, and the other end of the second vertical segment 7033 is connected to one end of the third straight segment 7034. The other end of the third straight segment 7034 is connected to one end of the first inclined segment 7035, and the other end of the first inclined segment 7035 is connected to one end of the fourth straight segment 7036. The other end of the fourth straight segment 7036 is connected to the third bending segment 704. The top surface of the fourth straight segment 7036 is in contact with the bottom surface of the support portion 5, and the included angle between the first inclined segment 7035 and the third straight segment 7034 is an obtuse angle.

[0102] The above settings ensure that the corner brackets are securely installed in the housing cavity 701, preventing displacement or loosening of the corner brackets during installation and enhancing the structural stability of the entire photovoltaic frame.

[0103] See also Figures 36 to 40 As shown, in some embodiments of this application, the second bending segment 703 includes a fifth straight segment 7038 extending along a first direction. The top surface of the fifth straight segment 7038 is in contact with the bottom surface of the support portion 5. One end of the fifth straight segment 7038 is connected to the end of the support portion 5 away from the stop portion 6, and the other end of the fifth straight segment 7038 is connected to the third bending segment 704.

[0104] Specifically, the top surface of the fifth straight section 7038 is in contact with the bottom surface of the support part 5. At this time, the fifth straight section 7038 can not only support the support part 5, but also increase the thickness of the support part 5, which can ensure the support stability of the support part 5.

[0105] See also Figures 41 to 50As shown, in some embodiments of this application, the second bending portion 7 further includes a second inclined segment 13, a third bending segment 704, and a fourth bending segment 705 connected in sequence. One end of the second inclined segment 13 is connected to the end of the support portion 5 away from the stop portion 6. The other end of the second inclined segment 13 extends downward in an inclined direction away from the support portion 5 and is connected to the third bending segment 704. The third bending segment 704 extends in a vertical direction, and the fourth bending segment 705 extends in a first direction. The first hook 702 is provided at the end of the fourth bending segment 705 away from the third bending segment 704.

[0106] Specifically, the second inclined section 13 allows the silicone 14 to be distributed over a larger area during filling, reducing the thickness of the silicone 14 at a single point. At the same time, the second inclined section 13 can guide the flow direction of the colloid, causing it to flow downwards along the slope of the second inclined section 13 instead of overflowing outwards, thereby reducing the possibility of the colloid overflowing under pressure.

[0107] In some embodiments of this application, both the long frame 1 and the short frame 4 are formed by bending steel.

[0108] Specifically, the long frame 1 and the short frame 4 are made of steel by bending. Compared with the traditional aluminum material, steel has higher yield strength and tensile strength, which can significantly improve the mechanical strength of the photovoltaic frame. At the same time, the long frame 1 and the short frame 4 are formed directly through the bending process, which can reduce the cost of mold development and material waste, as well as reduce production preparation time and cost.

[0109] See also Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figures 9 to 11 As shown, in some embodiments of this application, the slot 3 includes a first plate segment 31, a second plate segment 32 and a third plate segment 33 connected in sequence. The first plate segment 31 and the third plate segment 33 are located on the same side of the second plate segment 32, and the third plate segment 33 is connected to the first bending portion.

[0110] Specifically, the first plate segment 31, the second plate segment 32 and the third plate segment 33 can limit the long side of the laminate 2 from multiple directions. The first plate segment 31, the second plate segment 32 and the third plate segment 33 are filled with silicone 14 between themselves and the long side of the laminate, which can achieve the bonding and fixing of the laminate 2 and the long frame 1.

[0111] See also Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 9 , Figure 11As shown, in some embodiments of this application, the first plate segment 31 and the third plate segment 33 are both perpendicular to the second plate segment 32.

[0112] Specifically, the first plate segment 31 and the third plate segment 33 are both perpendicular to the second plate segment 32. The first plate segment 31, the second plate segment 32 and the third plate segment 33 form a U-shaped structure, and the opening of the U-shaped structure faces the long side of the laminate 2. This facilitates the insertion of the long side of the laminate 2, and after the laminate 2 is inserted into the slot 3, the overall structure is relatively flat and more aesthetically pleasing.

[0113] like Figure 8 As shown, in some embodiments of this application, the third plate segment 33 is perpendicular to the second plate segment 32, and the first plate segment 31 includes a sixth straight segment 312, a third inclined segment 8 and a seventh straight segment 9 connected sequentially in a direction away from the second plate segment 32. The sixth straight segment 312 is connected to and perpendicular to the second plate segment 32. The end of the third inclined segment 8 away from the sixth straight segment 312 extends downward at an incline toward the side where the third plate segment 33 is located. The seventh straight segment 9 is parallel to the third plate segment 33.

[0114] Specifically, the third inclined segment 8 can form a gradually narrowing opening, and the seventh straight segment 9 can increase the contact area between the first plate segment 31 and the upper surface of the laminate, thus ensuring the structural stability of the photovoltaic module.

[0115] See also Figure 10 , Figures 41 to 45 As shown, in some embodiments of this application, a first protrusion 10 extending away from the first plate segment 31 is provided at the connection position between the third plate segment 33 and the second plate segment 32.

[0116] The above settings enable further positioning of the corner codes, ensuring their relative stability.

[0117] See also Figure 14 , Figure 19 , Figure 24 , Figure 29 As shown, in some embodiments of this application, the end of the first vertical segment 61 away from the support portion 5 is bent toward the side where the support portion 5 is located to form a second stop edge 611. The second stop edge 611 is in contact with the inner wall surface of the first vertical segment 61 and is spaced apart from the support portion 5.

[0118] With the above settings, after the laminate is placed on the support part 5, the bottom surface of the second stop edge 611 abuts against the upper surface of the laminate. The setting of the second stop edge 611 can stop the silicone 14 filled between the support part 5, the first vertical section 61, the second stop edge 611 and the laminate, and prevent the silicone 14 from overflowing.

[0119] See also Figure 15 , Figure 20 , Figure 25 , Figure 30 As shown, in some embodiments of this application, the end of the first straight section 612 away from the first vertical section 61 is bent toward the side where the support part 5 is located to form a third stop edge 614, and the third stop edge 614 is in contact with the bottom surface of the first straight section 612.

[0120] With the above settings, after the laminate is placed on the support part 5, the bottom surface of the third stop edge 614 abuts against the upper surface of the laminate. The setting of the third stop edge 614 can stop the silicone 14 filled between the support part 5, the first vertical section 61, the third stop edge 614, the first straight section 612 and the laminate, and prevent the silicone 14 from overflowing.

[0121] See also Figures 26 to 30 As shown, in some embodiments of this application, the second bending segment 703 includes an eighth straight segment 7037 extending along a first direction. The top surface of the eighth straight segment 7037 is in contact with the bottom surface of the support portion 5. One end of the eighth straight segment 7037 is connected to the support portion 5 via a second hook 706. The second hook 706 protrudes toward the side where the fourth bending segment 705 is located. The other end of the eighth straight segment 7037 is connected to the third bending segment 704.

[0122] Through the above settings, the eighth straight section 7037 can support the support part 5, enhance the support strength and stability of the support part, and the second hook 706, together with the first hook 702, can limit the corner code, ensure the relative position of the corner code in the installation cavity, prevent the corner code from being displaced when the photovoltaic frame is subjected to external force, and thus ensure the structural stability of the photovoltaic module.

[0123] See also Figures 18 to 51 As shown, in some embodiments of this application, the third bending segment 704 is provided with a groove 11 recessed toward the side where the first hook 702 is located or a second protrusion 12 protruding away from the side where the first hook 702 is located.

[0124] The above-mentioned configuration can enhance the structural strength of the second bend 7.

[0125] In some embodiments of this application, the included angle α between the first hook 702 and the bottom wall of the second bend 7 is in the range of 0°≤α≤90°.

[0126] The above settings ensure effective positioning of the corner brackets and facilitate their insertion into the receiving cavity.

[0127] Preferably, the included angle α is in the range of 0°≤α≤45°.

[0128] like Figure 5As shown, in some embodiments of this application, the end of the first plate segment 31 that is away from the second plate segment 32 extends obliquely toward the side where the third plate segment 33 is located.

[0129] Specifically, the first plate segment 31 extends obliquely towards the side where the third plate segment 33 is located. When the long side of the laminate is inserted into the slot 3, the first plate segment 31 can press firmly against the upper surface of the laminate, which can reduce the probability of adhesive overflow and the risk of moisture intrusion. At the same time, the obliquely extended first plate segment 31 can improve the hydrodynamic characteristics of the frame edge. Under the action of natural rain or wind, the oblique surface helps to guide water flow and wind direction, thereby contributing to the self-cleaning of the photovoltaic frame.

[0130] See also Figure 3 and Figure 5 As shown, in some embodiments of this application, the end of the first plate segment 31 away from the second plate segment 32 is bent toward the bottom surface of the first plate segment 31 to form a first stop edge 311. The first stop edge 311 is attached to the bottom surface of the first plate segment 31 and has a gap with the second plate segment 32.

[0131] Specifically, the first stop edge 311 can stop the silicone 14 filled between the first plate segment 31, the second plate segment 32 and the third plate segment 33 and the laminate, preventing the silicone 14 from overflowing.
