Description

Technical Field

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

[0002] Photovoltaic modules are susceptible to external impacts, environmental corrosion, or installation stress, so they are often encapsulated with frames.

[0003] Traditional photovoltaic modules often use an integrated metal frame, which has problems such as inconvenient installation, inability to adapt to the deformation of laminates, and poor fit between the frame and the laminates.

[0004] Existing split-type frames require fasteners such as bolts for connection and fixation to be assembled on the edge of the photovoltaic laminate. However, when the photovoltaic laminate is subjected to impact and deformation, the photovoltaic frame cannot adapt to the deformation of the photovoltaic laminate, which is not conducive to protecting the photovoltaic laminate.

[0005] Therefore, a new edge protection structure for photovoltaic modules is urgently needed. Utility Model Content

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0066] As described in the background section, when a photovoltaic laminate is subjected to impact deformation, the photovoltaic frame cannot adapt to the deformation of the photovoltaic laminate, which can easily lead to stress concentration and breakage of the photovoltaic laminate, which is not conducive to protecting the photovoltaic laminate.

[0067] To address this, this utility model embodiment provides a split edge protection structure, such as... Figure 1 As shown, it includes: a first edge protector 200 and a second edge protector 300;

[0068] The first edge protector 200 is configured to be fixed to the upper surface 110 of the photovoltaic laminate 100, and the second edge protector 300 is configured to be fixed to the lower surface 120 of the photovoltaic laminate 100, and the first edge protector 200 and the second edge protector 300 cover at least a portion of the edge 130 of the photovoltaic laminate 100.

[0069] like Figure 2 As shown, the split edge protection structure has a deformable section 420 and a non-deformable section 410 located outside the deformable section 420. The deformability of the split edge protection structure at the deformable section 420 is greater than that at the non-deformable section 410.

[0070] According to the split edge protection structure provided in this embodiment of the utility model, the first edge protection 200 and the first edge protection 300 cooperate to protect the edges of the upper surface 110 and the lower surface 120 of the photovoltaic laminate 100, preventing the photovoltaic laminate 100 from breaking due to edge impact. By providing a deformable section 420 on the split edge protection structure, the rigidity of the split edge protection structure can be weakened at the deformable section 420 through its own deformation, increasing the deformability at that location. This allows the split edge protection structure to respond to the deformation of the photovoltaic laminate 100 and generate displacement matching, avoiding stress concentration caused by deformation mismatch between the photovoltaic laminate 100 and the edge protection structure.

[0071] The split edge protection structure provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0072] according to Figure 1 The present invention provides an exemplary embodiment of a split edge protection structure, which includes a first edge protection 200 and a second edge protection 300.

[0073] See Figure 1 The first edge protector 200 and the second edge protector 300 are separately disposed on the upper surface 110 and the lower surface 120 of the photovoltaic laminate 100, and are joined together at the edge 130 of the photovoltaic laminate 100 to form a joint area, so as to protect the edge 130 of the photovoltaic laminate 100.

[0074] Specifically, in this embodiment, the first edge protector 200 includes a first horizontal portion 210 that engages with the upper surface 110 of the photovoltaic laminate 100 and a first shielding portion 220 that extends toward the edge 130 of the photovoltaic laminate 100; the second edge protector 300 includes a second horizontal portion 310 that engages with the lower surface 120 of the photovoltaic laminate 100 and a second shielding portion 320 that extends toward the edge 130 of the photovoltaic laminate 100; the first shielding portion 220 and the second shielding portion 320 are joined together at the edge 130 of the photovoltaic laminate 100.

[0075] For example, see Figure 1 The first edge protector 200 has an "L"-shaped structure, including a first horizontal portion 210 and a first vertical portion. The first horizontal portion 210 is parallel to the upper surface 110 of the photovoltaic laminate 100 and is bonded and fixed to the upper surface 110 of the photovoltaic laminate 100 through a lamination process. The first vertical portion bends downwards from the side of the first horizontal portion 210 to the edge 130 of the photovoltaic laminate 100, forming a first shielding portion 220 that covers at least a portion of the edge 130.

[0076] The second edge protector 300 also has an "L"-shaped structure, including a second horizontal portion 310 and a second vertical portion. The second horizontal portion 310 is parallel to the lower surface 120 of the photovoltaic laminate 100 and is fixed to the lower surface 120 of the photovoltaic laminate 100 through a lamination process. The second vertical portion bends upward from the side of the second horizontal portion 310 to the edge 130 of the photovoltaic laminate 100, forming a second shading portion 320 that covers at least a portion of the edge 130.

[0077] In this design, the first horizontal portion 210 of the first edge protector 200 and the second horizontal portion 310 of the second edge protector 300 face each other in the thickness direction of the photovoltaic laminate 100. Both the first horizontal portion 210 and the second horizontal portion 310 are rigid planar plate structures to facilitate lamination between the first horizontal portion 210, the second horizontal portion 310 and the photovoltaic laminate 100. Specifically, since the edge protector structure is a rigid component, it provides support for the edge 130 of the photovoltaic laminate 100 body. Therefore, the module does not require a lamination frame during the lamination process, which can reduce production costs. For example, both the first edge protector 200 and the second edge protector 300 are made of metal materials, such as aluminum alloy or stainless steel, to ensure the rigidity of the first horizontal portion 210 and the second horizontal portion 310, facilitating lamination.

[0078] The bonding process between the first horizontal portion 210 and the second horizontal portion 310 and the photovoltaic laminate 100 can be specifically as follows:

[0079] First, a material with adhesive function, such as pressure-sensitive adhesive, hot melt adhesive or hot melt adhesive film, silicone, etc., is applied to the surfaces of the first horizontal portion 210 and the second horizontal portion 310 facing the photovoltaic laminate 100.

[0080] Then, the first horizontal part 210 is bonded and pre-fixed to the upper surface 110 of the photovoltaic laminate 100 in sequence, and the second horizontal part 310 is bonded and pre-fixed to the lower surface 120 of the photovoltaic laminate 100.

[0081] Finally, the edges of the components are sealed with edge sealing tape before they are put into the laminator for lamination.

[0082] It should be understood that the above-mentioned lamination operation can be carried out simultaneously with the lamination operation of the photovoltaic laminate 100 itself. For example, photovoltaic glass, battery strings, encapsulant film, etc. can be pre-assembled into a pre-laminated component (unlaminated), and then the first edge protector 200 and the second edge protector 300 can be bonded to the pre-laminated component to form a whole. Then, it can be placed into a laminator for pressing. In this way, the overall lamination efficiency of the photovoltaic module can be improved.

[0083] Of course, the lamination of the first edge protector 200 and the second edge protector 300 can also be carried out separately after the photovoltaic laminate 100 is laminated.

[0084] Among them, see Figure 1 The joint area of ​​the first edge 200 and the second edge 300 at the edge 130 of the photovoltaic laminate 100 is formed by the first shielding portion 220 and the second shielding portion 320 joining together.

[0085] In this embodiment, the mutual engagement between the first shielding part 220 and the second shielding part 320 can be overlapping, abutting, or plugging.

[0086] The overlapping refers to the inner and outer overlap of the first shielding part 220 and the second shielding part 320 at the edge 130. In this way, the thickness of the first shielding part 220 and the second shielding part 320 can be superimposed, increasing the thickness of the protective layer of the photovoltaic laminate 100 at the edge 130 and improving the protective effect.

[0087] For example, see Figures 1 to 3 In the thickness direction of the photovoltaic laminate 100, the first shielding part 220 and the second shielding part 320 are staggered from each other, and at least partially overlap in the direction perpendicular to the thickness direction of the photovoltaic laminate 100, so that the thickness of the first shielding part 220 and the second shielding part 320 can be superimposed.

[0088] Specifically, see Figure 1The second shielding portion 320 is attached to the edge 130 of the photovoltaic laminate 100, and its upper end does not exceed the upper surface 110 of the photovoltaic laminate 100. The first shielding portion 220 is attached to the outside of the second shielding portion 320, and its lower end extends downward to below the upper end of the second shielding portion 320, so that the two overlap at least partially. In this way, the first shielding portion 220 and the second shielding portion 320 can be joined together to form a protective layer that covers and protects the edge 130 of the photovoltaic laminate 100.

[0089] Further, see Figure 1 The lower end of the first blocking part 220 extends downward to be flush with the lower surface 120 of the second edge protector 300, so that the first blocking part 220 can completely cover the second edge protector 300, improving the overall aesthetics.

[0090] Furthermore, the height of the second shielding part 320 is not less than the thickness of the photovoltaic laminate 100. With this configuration, the second shielding part 320 can avoid excessive compression of the photovoltaic laminate 100 during lamination.

[0091] In the above embodiment, the second shielding portion 320 can be fixed to the edge 130 of the photovoltaic laminate 100 using an adhesive material. Similarly, the first shielding portion 220 and the second shielding portion 320, as well as the first shielding portion 220 and the edge 130 of the photovoltaic laminate 100, can also be fixed using adhesive materials. This improves the fixing effect of the first edge protector 200 and the second edge protector 300, forming a sealed protection for the edge 130 of the photovoltaic laminate 100.

[0092] The abutting refers to the first shielding part 220 and the second shielding part 320 forming an abutting contact at the edge 130. This can reduce the thickness of the protective layer of the photovoltaic laminate 100 at the edge 130, reduce the overall area, and also reduce the amount of material used in the first edge protector 200 and the second edge protector 300, thereby reducing costs.

[0093] For example, see Figure 4 and Figure 5 In the thickness direction of the photovoltaic laminate 100, the first shielding portion 220 and the second shielding portion 320 face each other and are both disposed in contact with the edge 130 of the photovoltaic laminate 100. At the same time, the lower surface 120 of the first shielding portion 220 and the upper surface 110 of the second shielding portion 320 abut against each other to form a complete shielding portion, which can completely cover the edge 130 of the photovoltaic laminate 100 in the thickness direction.

[0094] In this case, the sum of the heights of the first shielding portion 220 and the second shielding portion 320 is equal to or slightly greater than the thickness of the edge 130 of the photovoltaic laminate 100. When the first horizontal portion 210 and the second horizontal portion 310 are attached to the upper and lower surfaces 120 of the photovoltaic laminate 100, the first shielding portion 220 and the second shielding portion 320 can just abut and combine to form a complete shielding portion, covering and protecting the edge 130. For example, the heights of the first shielding portion 220 and the second shielding portion 320 are both half the thickness of the edge 130.

[0095] Similarly, in the abutting fit embodiment, the first shielding part 220 and the second shielding part 320 can also be fixed to the edge 130 of the photovoltaic laminate 100 by adhesive material.

[0096] The "plugging" refers to the mutual insertion and engagement of the lower side of the first shielding part 220 and the upper side of the second shielding part 320 to form a shielding part that can completely cover the edge 130 in the thickness direction. Thus, through the plugging and engagement of the first shielding part 220 and the second shielding part 320, the thickness of the protective layer of the photovoltaic laminate 100 at the edge 130 can be reduced, the overall area and material usage can be decreased, while the bonding tightness of the first shielding part 220 and the second shielding part 320 can be improved, thereby enhancing the protective effect.

[0097] For example, see Figures 6 to 8 In the thickness direction of the photovoltaic laminate 100, the first shielding part 220 and the second shielding part 320 are vertically aligned and both are attached to the edge 130 of the photovoltaic laminate 100. At the same time, a matching plug-in structure is provided between the lower side of the first shielding part 220 and the upper side of the second shielding part 320, which allows the two to be plugged in and mated.

[0098] Among them, see Figure 6 and Figure 7 Specifically, the plug-in structure can be provided with a plurality of staggered protrusions 500 on the lower side of the first shielding part 220 and the upper side of the second shielding part 320. The staggered protrusions 500 constitute the plug-in structure, and the first shielding part 220 and the second shielding part 320 can be plugged into each other through the staggered protrusions 500.

[0099] For more details, see Figure 7 The protrusions 500 on the lower side of the first blocking portion 220 are first protrusions 510, and the first protrusions 510 are arranged at intervals, so that a first recess 540 is formed between adjacent first protrusions 510. The protrusions 500 on the upper side of the second blocking portion 320 are second protrusions 520, and the second protrusions 520 are arranged at intervals, so that a second recess 550 is formed between adjacent second protrusions 520.

[0100] The widths of the first protrusion 510 and the second recess 550 are adapted to each other, and the first protrusion 510 and each of the second recesses 550 are vertically aligned; the widths of the second protrusion 520 and the first recess 540 are adapted to each other, and the second protrusion 520 and each of the first recesses 540 are vertically aligned. Thus, by inserting the first protrusions 510 on the lower side of the first blocking part 220 into the second recesses 550 on the upper side of the second blocking part 320, and by inserting the second protrusions 520 on the upper side of the second blocking part 320 into the first recesses 540 on the lower side of the first blocking part 220, the first blocking part 220 and the second blocking part 320 can be connected and engaged.

[0101] In this embodiment, the shapes of the protrusions 500 and the recesses are not limited, as long as the insertion and mating of the protrusions 500 and the recesses can be ensured. For example, Figure 7 The example shows that each protrusion 500 and each recess is rectangular. Similarly, this embodiment does not limit the number of each protrusion 500 and each recess; they can be located at partial positions of the first shielding portion 220 and the second shielding portion 320, or they can cover the entire edge protection structure along the length direction.

[0102] In this embodiment, the height of each protrusion 500 is not specifically limited. For example, the heights of each first protrusion 510 and each second protrusion 520 can be the same or different. However, the heights of each protrusion 500 and each corresponding recess should meet the following conditions: when the top end of the protrusion 500 and the bottom end of the corresponding recess abut and are limited, the horizontal portions of the first edge protector 200 and the second edge protector 300 are just adhered to the surface of the photovoltaic laminate 100 by the adhesive material, ensuring the fixing effect of the first edge protector 200 and the second edge protector 300, and also ensuring the closed joint between the protrusion 500 and the corresponding recess. At the same time, it avoids excessive compression between the first edge protector 200 and the second edge protector 300 and the photovoltaic laminate 100, ensuring the uniformity of the thickness of the photovoltaic module body. For example, Figure 6 An exemplary embodiment is shown in which the heights of the protrusions 500 and the recesses are the same.

[0103] In this embodiment, the width of each first protrusion 510 and each second protrusion 520 is not specifically limited. For example, the width of each first protrusion 510 and each second protrusion 520 can be the same or different, as long as it can ensure that each protrusion 500 can form an interlocking fit with each recess. For example, Figure 7 An exemplary embodiment is shown in which the widths of the protrusions 500 and the recesses are the same.

[0104] Similarly, in the plug-in mating embodiment, the first shielding part 220 and the second shielding part 320 can also be fixed to the edge 130 of the photovoltaic laminate 100 by adhesive material.

[0105] Based on the above, in this embodiment, the first edge protector 200 and the second edge protector 300 are integrally press-fitted with the photovoltaic laminate 100 by lamination. The shielding parts of the two form protection for the edge 130 of the photovoltaic laminate 100 through simple overlapping, abutment, or insertion. This simplifies the installation steps of the first edge protector 200 and the second edge protector 300, improves installation efficiency, eliminates the need for bolts and other fasteners, and improves aesthetics and weather resistance. It also ensures full contact between the edge protector structure and the photovoltaic laminate 100 body, ensuring reliable connection. This design can replace conventional frames and save costs.

[0106] In addition, during the installation of photovoltaic modules, the edge protection structure also plays a role in fixing the photovoltaic bracket. Specifically, when the photovoltaic module is installed on the photovoltaic bracket, the edge protection structure needs to be pressed tightly onto the photovoltaic bracket by the pressure block 800 to achieve the fixed positioning of the photovoltaic module.

[0107] However, because the pressure block 800 fixes and limits the edge protection structure, when the photovoltaic laminate 100 is subjected to external force (such as the pressure exerted on it by wind or snow) and undergoes bending deformation, the edge protection structure cannot deform synchronously, which in turn makes the photovoltaic glass prone to breakage due to stress concentration.

[0108] In this embodiment, a stress-relieving area is provided in the area of ​​the edge protection structure corresponding to the mounting block 800, so that the corresponding area of ​​the edge protection structure can deform in response to the deformation of the photovoltaic laminate 100, thereby avoiding stress concentration in the photovoltaic glass.

[0109] For details, see Figure 2 In this embodiment, based on functional division, the split edge protection structure can be divided along its length into a deformable segment 420 and a non-deformable segment 410. The non-deformable segment 410 includes a press-fit fixed segment 411 and a non-fixed segment 412. The press-fit fixed segment 411 is configured to be fixed by an external fastener. The deformable segment 420 is connected to the press-fit fixed segment 411 to reduce the rigid constraint of the split edge protection structure at both ends of the press-fit fixed segment 411.

[0110] Among them, the press-fit fixing section 411 is the area on the edge protection structure used for fixing external fasteners. The external fasteners are mainly pressure blocks 800. That is to say, after the pressure blocks 800 are pressed onto the press-fit fixing section 411 of the edge protection structure, the photovoltaic module can be fixed as a whole. After installation, the press-fit fixing section 411 of the edge protection structure is in a fixed position.

[0111] In this embodiment, the number of press-fit fixing sections 411 on the edge protection structure can be determined based on the number of pressing blocks 800 installed, and no specific limitation is made here. For example, if the number of pressing blocks 800 installed on the edge protection structure is usually two, then the press-fit fixing sections 411 can also be set to two accordingly.

[0112] The non-fixed section 412 is the area in the non-deformable section 410 of the edge protector structure that is not installed with a pressure block. For example, corresponding to the design of the edge protector structure having two pressure-fixed sections 411, the area of ​​the non-deformable section 410 located between the two pressure-fixed sections 411 and the areas located on both sides of the two pressure-fixed sections 411 are both non-fixed sections 412.

[0113] In this embodiment, since the non-fixed segment 412 is not completely fixed by the pressure block 800, it still has the condition of being deformable and can be used to match the deformation of the photovoltaic laminate 100.

[0114] See Figure 2 , Figure 4 , Figure 9 and Figure 10 In this embodiment, the edge protection structure is provided with a deformable section 420 in the area between each non-fixed section 412 and the press-fit fixed section 411. The deformable section 420 is the aforementioned stress release area. The stress of the photovoltaic laminate 100 is released through the deformable section 420 to avoid breakage caused by stress concentration.

[0115] Specifically, in this embodiment, the edge protection structure has a high deformability at the deformable section 420, meaning that the deformability at the deformable section 420 is greater than that at the non-fixed section 412 and the press-fit fixed section 411. This makes the deformable section 420 a relatively flexible connection between the press-fit fixed section 411 and the non-fixed section 412. When the photovoltaic laminate 100 deforms, it can respond quickly and bridge the deformation difference between the press-fit fixed section 411 and the non-fixed section 412, weakening the rigid constraint between the press-fit fixed section 411 and the non-fixed section 412. This reduces or breaks the rigid constraint force applied by the press-fit fixed section 411 to the non-fixed section 412, allowing the non-fixed section 412 to respond to the deformation of the photovoltaic laminate 100 and generate displacement matching, thus avoiding stress concentration caused by deformation mismatch between the photovoltaic laminate 100 and the edge protection structure.

[0116] Specifically, the displacement matching of the non-fixed section 412 in response to the deformation of the photovoltaic laminate 100 is manifested as follows: when the photovoltaic laminate 100 is subjected to external force, the photovoltaic laminate 100 as a whole will undergo a certain bending deformation. Since the area of ​​the photovoltaic laminate 100 corresponding to the press-fit fixed section 411 is fixed by the press block 800, this area will not deform. However, the area that is offset from the press block 800 will undergo a certain deformation. This offset area corresponds to the non-fixed section 412 area of ​​the edge protection structure. Therefore, the deformed area of ​​the photovoltaic laminate 100 will exert pressure on the non-fixed section 412 of the edge protection structure. When the non-fixed section 412 is subjected to pressure, the pressure is transmitted along the edge protection structure to the deformable section 420. The deformable section 420 can deform based on the pressure, thereby weakening the rigid constraint between the press-fit fixed section 411 and the non-fixed section 412. This allows the non-fixed section 412 to undergo displacement deformation relative to the press-fit fixed section 411. This displacement deformation is based on the bending deformation of the photovoltaic laminate 100. Therefore, the displacement deformation of the non-fixed section 412 of the edge protection structure and the bending deformation of the photovoltaic laminate 100 are in the same direction, so that the deformation of the non-fixed section 412 can match the deformation of the photovoltaic laminate 100.

[0117] Based on the above, the deformable section 420 connects and transitions the non-deformable area corresponding to the press-fit fixed section 411 and the deformation area corresponding to the non-fixed section 412, so that the bending deformation of the edge protection structure and the photovoltaic laminate 100 is synchronized, avoiding the situation where the photovoltaic laminate 100 bends while the edge protection structure does not bend, thereby avoiding stress concentration caused by the deformation difference between the photovoltaic laminate 100 and the edge protection structure.

[0118] Specifically, in this embodiment, the deformability of the deformable section 420 of the edge protection structure can be improved by performing local processing on the deformable section 420.

[0119] For example, in some embodiments, the deformable segment 420 may be made of a material with a stiffness less than that of the press-fitted fixed segment 411 and the non-fixed segment 412, in order to increase the deformability of the deformable segment 420.

[0120] For example, a deformable structure 421 can be provided in the part of the edge protection structure corresponding to the deformable section 420 to increase the flexibility of the deformable section 420.

[0121] In this embodiment, it is preferable to increase the toughness of the deformable segment 420 by setting a deformable structure 421. This design is easier to implement and can simplify the processing steps.

[0122] For details, see Figures 2 to 10In this embodiment, the deformable structure 421 can be: the first shielding part 220 and / or the second shielding part 320 are provided with at least one deformation joint 4211 in the area corresponding to the deformable section 420. The deformation joint 4211 can disrupt the material continuity of the edge protection structure at the deformable section 420, reduce its bending resistance, enhance its deformability, and connect the deformation difference between the press-fitted fixed section 411 and the non-fixed section 412 through deformation.

[0123] For more details, see Figure 3 and Figure 5 In the thickness direction of at least one of the first shielding portion 220 and the second shielding portion 320, the expansion joint 4211 penetrates through the corresponding shielding portion. For example, the expansion joint 4211 corresponding to the first shielding portion 220 should penetrate through the first shielding portion 220; for example, the expansion joint 4211 corresponding to the second shielding portion 320 should penetrate through the second shielding portion 320. This ensures that the expansion joint 4211 can break the material continuity of the corresponding shielding portion in the thickness direction. The thickness direction of the shielding portion is perpendicular to the edge of the photovoltaic laminate.

[0124] See also Figure 3 and Figure 5 In the height direction of at least one of the first shielding portion 220 and the second shielding portion 320, the expansion joint 4211 extends to the free side of the corresponding shielding portion, so that the expansion joint 4211 constitutes an opening. The free side of the shielding portion refers to the side of the shielding portion away from its corresponding horizontal portion, i.e., the lower side of the first shielding portion 220 and the upper side of the second shielding portion 320; the height direction of the shielding portion refers to the direction perpendicular to the upper surface 110 or the lower surface 120 of the photovoltaic laminate 100. For example, the expansion joint 4211 provided on the first shielding portion 220 should extend downward through the free side of the first shielding portion 220; and, for example, the expansion joint 4211 provided on the second shielding portion 320 should extend upward through the second shielding portion 320. In this way, it can be ensured that the expansion joint 4211 can break the material continuity of the corresponding shielding part in the height direction. Combined with the design of the expansion joint 4211 penetrating the shielding part in the thickness direction, it can be ensured that the expansion joint 4211 can disrupt the material continuity of the edge protection structure at the deformable section 420, thereby improving its deformability.

[0125] The way the expansion joint 4211 is set is also different depending on the different ways the first shielding part 220 and the second shielding part 320 are connected.

[0126] For example, the mating method corresponding to the first shielding part 220 and the second shielding part 320 overlapping each other.

[0127] See Figure 2 and Figure 3Both the first shielding part 220 and the second shielding part 320 are provided with slits, which are deformation slits 4211. The deformation slits 4211 on the first shielding part 220 and the second shielding part 320 are opposite to each other along the thickness direction of the shielding part, that is, in the direction perpendicular to the edge 130 of the photovoltaic laminate 100. In this way, the first shielding part 220 and the second shielding part 320 can deform at the same position.

[0128] For example, a mating arrangement in which the first blocking part 220 and the second blocking part 320 abut against each other.

[0129] See Figure 4 and Figure 5 Both the first shielding part 220 and the second shielding part 320 are provided with slits, which are deformation slits 4211. The deformation slits 4211 on the first shielding part 220 and the second shielding part 320 are opposite each other along the height direction of the shielding part, so that the first shielding part 220 and the second shielding part 320 can deform at the same position.

[0130] Further, see Figure 11 and Figure 12 When the first edge protector 200 and the second edge protector 300 are lapped or abutted, a limiting structure 600 can be provided between the first shielding part 220 and the second shielding part 320. The limiting structure 600 is configured to limit the relative displacement of the first edge protector 200 and the second edge protector 300 along the length direction of the edge 130. In this way, the limiting structure 600 can realize the relative positioning of the first edge protector 200 and the second edge protector 300, ensuring the alignment accuracy of the deformation joint 4211 between them, and ensuring the synchronous deformation effect of the two.

[0131] For example, participate Figure 12 The limiting structure 600 includes a limiting hole 610 disposed on the first blocking part 220 and a limiting tooth 620 disposed on the second blocking part 320. The limiting tooth 620 extends toward the limiting hole 610 and cooperates with the limiting hole 610 for limiting.

[0132] See Figure 12 When the second blocking part 320 and the first blocking part 220 overlap, the limiting hole 610 and the limiting tooth 620 are disposed at the inner and outer relative positions of the second blocking part 320 and the first blocking part 220.

[0133] When the first blocking part 220 and the second blocking part 320 are in vertical contact, the limiting hole 610 and the limiting tooth 620 are disposed at the vertical relative positions of the first blocking part 220 and the second blocking part 320.

[0134] Thus, during installation, the relative positioning of the two parts can be achieved by inserting the limiting teeth 620 on the second blocking part 320 into the limiting holes 610 on the first blocking part 220, ensuring their positioning accuracy.

[0135] For example, a mating arrangement in which the first shielding part 220 and the second shielding part 320 are interlocked.

[0136] See Figure 6 and Figure 10 Along the thickness direction of the photovoltaic laminate 100, the first shielding portion 220 and the second shielding portion 320 are vertically opposite each other, and a plurality of staggered protrusions 500 are provided on the lower side of the first shielding portion 220 and the upper side of the second shielding portion 320. The first shielding portion 220 and the second shielding portion 320 are engaged by the staggered protrusions 500, and these protrusions 500 constitute a limiting structure 600. In this embodiment, the mutually engaging protrusions 500 constitute the limiting structure 600, which can also limit the relative displacement of the first edge guard 200 and the second edge guard 300 along the length direction of the edge 130.

[0137] In the deformable section 420, the expansion joint 4211 is formed on the protrusion 500 and / or between two adjacent protrusions 500. For example, see Figure 10 The joint between the first protrusion 510 and the second protrusion 520 can be directly regarded as the expansion joint 4211; for example, see Figure 9 Alternatively, a deformation joint 4211 can be formed by making separate slits on the first protrusion 510 and / or the second protrusion 520.

[0138] Further, see Figure 9 In this embodiment, multiple deformation joints 4211 are spaced apart within the deformable section 420 along the length of the edge protection structure. Thus, these multiple deformation joints 4211 further disrupt the material continuity at the deformable section 420, enhancing its deformation capacity and enabling it to better bridge the deformation differences between the press-fitted fixed section 411 and the non-fixed section 412.

[0139] See Figure 9 Corresponding to the design of the multiple expansion joints 4211 mentioned above, a spacer block 4212 is formed between each adjacent expansion joint 4211. The formation method of the spacer block 4212 varies depending on the formation method of the expansion joints 4211.

[0140] For example, corresponding to the above method of forming an expansion joint 4211 by opening a slot, then, as Figure 2 , Figure 4 and Figure 9As shown, the spacer block 4212 is formed after the deformation slit 4211 is opened on the shielding part / protrusion 500.

[0141] For example, corresponding to the embodiment described above where the seam between the first protrusion 510 and the second protrusion 520 is considered as a deformation joint 4211, then, as Figure 10 As shown, the first protrusion 510 and the second protrusion 520 themselves serve as spacer blocks 4212.

[0142] Further, see Figure 10 In this embodiment, along the direction from the deformable section 420 to the press-fitting fixed section 411, the width of each spacer 4212 decreases sequentially. That is to say, the spacer 4212 closest to the press-fitting fixed section 411 has the smallest width, while the spacer 4212 closest to the non-fixed section 412 has the largest width.

[0143] It is easy to understand that the narrower the width of the spacer block 4212, the smaller the distance between two adjacent deformation joints 4211, and the stronger the bending deformation capacity at that point. Therefore, this indicates that the deformation capacity is strongest in the area of ​​the deformable section 420 near the press-fit fixing section 411, and weakest in the area far from the press-fit fixing section 411. This design allows the deformation law of the deformable section 420 to match the deformation law of the photovoltaic laminate 100, achieving synchronous bending of both. This reduces or eliminates abrupt strain points during photovoltaic glass bending, improving the protection capability of the photovoltaic laminate 100.

[0144] Correspondingly, depending on the formation method of the corresponding spacer block 4212, the setting method of the different widths of each spacer block 4212 is also different.

[0145] For example, in the embodiment where each spacer block 4212 is formed after the expansion joint 4211 is opened, the different widths of the different spacer blocks 4212 are mainly achieved by changing the opening spacing between adjacent expansion joints 4211.

[0146] For example, in the embodiment where the first protrusion 510 and the second protrusion 520 themselves serve as spacers 4212, the variation in the width of different spacers 4212 is mainly achieved by changing the width of each first protrusion 510 and each second protrusion 520 themselves.

[0147] join Figure 10In one specific embodiment, corresponding to the first blocking portion 220 and the second blocking portion 320 of the plug-in mating, a deformable segment 420 has a plurality of first protrusions 510 and second protrusions 520, and the width of each first protrusion 510 and second protrusion 520 gradually decreases along the direction from the non-fixed segment 412 to the press-fit fixed segment 411, thereby forming a combination of spacers 4212 with decreasing width, that is, the first protrusions 510 and the second protrusions 520 in this area are all spacers 4212.

[0148] Furthermore, in the above embodiments, when each protrusion 500 covers the entire edge protection structure along its length, i.e., when the non-fixed section 412, the deformable section 420, and the press-fit fixed section 411 all have protrusions 500 and corresponding recesses, the relationship between each protrusion 500 should satisfy the following: the width of each first protrusion 510 and second protrusion 520 forming the spacer block 4212 in the deformable section 420 should be smaller than the width of each first protrusion 510 and second protrusion 520 in the non-fixed section 412. This ensures that the deformable section 420 has a greater deformability than the non-fixed section 412, guaranteeing that it can bridge the deformation differences between the press-fit fixed section 411 and the non-fixed section 412.

[0149] join Figure 9 In another specific embodiment, corresponding to the first shielding part 220 and the second shielding part 320 of the plug-in mating, there is only one protrusion 500 in a deformable section 420. The protrusion 500 can be the first protrusion 510 or the second protrusion 520, and the protrusion 500 is provided with a plurality of deformation seams 4211. The plurality of deformation seams 4211 divide the protrusion 500 into a plurality of spacer blocks 4212. The width of the plurality of spacer blocks 4212 gradually decreases along the direction from the non-fixed section 412 to the press-fit fixed section 411.

[0150] Similarly, in the above embodiments, the width of each spacer block 4212 formed on the protrusion 500 is smaller than the width of each first protrusion 510 and second protrusion 520 in the non-fixed segment 412, so as to ensure that the deformable segment 420 has a greater deformability than the non-fixed segment 412.

[0151] Further, see Figure 9 and Figure 10 In this embodiment, the press-fit fixing section 411 corresponds to one of the protrusions 500, which can be a first protrusion 510 or a second protrusion 520, and the protrusion 500 is a continuous, seamless structure. This ensures the continuity of material at the press-fit fixing section 411, increases the press-fitting stability of the press-fit fixing section 411, and improves its fixing effect.

[0152] In this embodiment, a water-guiding structure is also provided on the edge protection structure. The water-guiding structure is used to drain liquid or particulate matter from the upper surface 110 of the photovoltaic laminate 100 to achieve self-cleaning.

[0153] In some embodiments, the water-guiding structure may include a first water-guiding notch 230 extending from the upper surface 110 of the photovoltaic laminate 100 to the outside of the split edge protection structure.

[0154] For example, see Figure 13 In one example, a first water-guiding notch 230 is provided on the first horizontal portion 210 of the first guard edge 200. The first water-guiding notch 230 extends from the free end of the first horizontal portion 210 toward the first shielding portion 220 and is connected to the outside of the split guard edge structure.

[0155] For example, see Figure 14 In another example, the first guard edge 200 is a split guard edge, which includes two or more first sub-guard edges 240. The two or more first sub-guard edges 240 are spaced apart on the edge 130 of the photovoltaic laminate 100, and a first water-guiding gap 230 is formed between the horizontal portions of two adjacent first sub-guard edges 240.

[0156] In this embodiment, preferably, the second shielding portion 320 is located inside the first shielding portion 220. This arrangement prevents rainwater from directly entering between the split edge protection structure and the edge 130 of the photovoltaic laminate 100, ensuring a waterproof effect.

[0157] Based on the above structural design, liquid or particulate matter on the upper surface 110 of the photovoltaic laminate 100 can be discharged outward from the edge 130 through the first water-guiding notch 230.

[0158] It should be understood that in the above embodiments, when the upper end of the second shielding part 320 of the second guard edge 200 is higher than the upper surface 110 of the photovoltaic laminate 100, a notch is also provided at the position opposite to the first water-guiding notch 230, so that the accumulated water can be smoothly discharged through the first water-guiding notch 230.

[0159] In some other embodiments, the water guiding structure may include a water guiding channel 250 extending from the upper surface 110 of the photovoltaic laminate 100 to the outside of the split edge protection structure.

[0160] For example, a water-guiding groove can be formed on the lower surface of the first horizontal portion 210 of the first edge protector 200, extending outward through the first shielding portion 220. Thus, when the first edge protector 200 is fixed to the upper surface 110 of the photovoltaic laminate 100, the water-guiding groove and the upper surface 110 of the photovoltaic laminate 100 can form a water-guiding channel 250. See, for example... Figure 15The water channel 250 extends from the free end of the first horizontal part 210 to the first shielding part 220 and connects to the outside of the split edge protection structure. In this way, liquid or particulate matter on the upper surface 110 of the photovoltaic laminate 100 can be discharged outward from the edge 130 through the water channel 250.

[0161] Similarly, in the above embodiment, when the upper end of the second shielding part 320 of the second guarding edge 200 is higher than the upper surface 110 of the photovoltaic laminate 100, a drainage hole is provided at the position of the second shielding part 320 opposite to the water guiding channel 250, so that the accumulated water can be smoothly discharged through the water guiding channel 250.

[0162] For example, in some embodiments, see [link to relevant documentation]. Figure 16 A first adhesive member 260 is provided between the first horizontal portion 210 and the upper surface 110 of the photovoltaic laminate 100, see [reference]. Figure 15 A second adhesive 330 is provided between the second horizontal portion 310 and the lower surface 120 of the photovoltaic laminate 100; wherein at least a portion of the first adhesive 260 does not cover the upper surface 110 of the photovoltaic laminate 100, and the uncovered portion forms a water channel 250 between the first horizontal portion 210 and the upper surface 110 of the photovoltaic laminate 100, the water channel 250 connecting the upper surface 110 of the photovoltaic laminate 100 to the outside of the split edge protection structure. For example, see Figure 16 The first adhesive members 260 are spaced apart, such that the portion between adjacent first adhesive members 260 is a cavity. This cavity is formed by the lower side of the first horizontal portion 210 and the upper surface 110 of the photovoltaic laminate 100. This cavity is the water channel 250, and the water channel 250 is located between two adjacent first protrusions 510, that is, at the first recess 540.

[0163] In addition, when a water guide groove is provided on the lower side of the first horizontal part 210 of the first edge protector 200, the first adhesive 260 is not covered by the water guide groove, ensuring that the water guide channel 250 formed by the water guide groove can be connected to the outside of the split edge protector structure.

[0164] In this embodiment, both the first adhesive 260 and the second adhesive 330 are materials with adhesive functions, such as pressure-sensitive adhesive, hot melt adhesive or hot melt adhesive film, silicone, etc.

[0165] Further, see Figure 15 and Figure 17The first shielding portion 220 and the second shielding portion 320 are arranged vertically opposite each other, and a gap 530 is formed between the second shielding portion 320 and the first shielding portion 220, which communicates with the water guiding channel 250. For example, there is a gap 530 between the upper end of the second protrusion 520 of the second shielding portion 320 and the upper end of the corresponding first recess 540, and the upper end of the first recess 540 is higher than the upper surface 110 of the photovoltaic laminate 100. Thus, since the gap 530 is located at the first recess 540, and the water guiding channel 250 is also located at the first recess 540, the gap 530 is exactly opposite to the position of the water guiding channel 250, so the gap 530 can form a water outlet communicating with the water guiding channel 250.

[0166] Based on the above, the material thickness of the first edge protector 200 in this solution is relatively low (0.5~1.5mm), and a water-guiding hollow structure is designed on the first edge protector 200, which can realize the function of guiding water and draining dirt on the front of the photovoltaic module, which is conducive to cleaning the dust accumulation of the module.

[0167] On the other hand, this embodiment of the invention also provides a photovoltaic frame, such as... Figure 18 As shown, the photovoltaic frame 700 is a rectangular frame with a short side 720 and a long side 710.

[0168] In this embodiment, both long sides 710 of the photovoltaic frame 700 are composed of the split edge protection structure of any of the above embodiments. Similarly, the two short sides 720 of the photovoltaic frame 700 can also be the split edge protection structure of any of the above embodiments, which facilitates the overall pressing of the photovoltaic frame 700. It should be understood that the relevant structure of the deformable segment 420 can be removed from the split edge protection structure constituting the short side 720 of the photovoltaic frame 700.

[0169] Furthermore, this embodiment of the invention also provides a photovoltaic module, see [link to relevant documentation]. Figure 19 It includes the photovoltaic frame 700 and the photovoltaic laminate 100 of the above embodiments, with the photovoltaic frame 700 assembled on the edge of the photovoltaic laminate 100.

[0170] See Figure 20 In this embodiment, the photovoltaic module further includes a pressing block 800, which is pressed onto the pressing and fixing section 411. Exemplarily, each long side 710 of the photovoltaic frame 700 is provided with a pressing block 800, and the number of pressing blocks 800 on each long side 710 is the same as the number of pressing and fixing sections 411 on the split edge protection structure. Each pressing block 800 is pressed onto each pressing and fixing section 411 of the split edge protection structure to ensure the overall positioning stability of the photovoltaic module.

[0171] See Figure 19In this embodiment, the water-guiding structure of the long side 710 of the photovoltaic frame 700 is a water-guiding channel 250 formed between the first horizontal portion 210 and the upper surface 110 of the photovoltaic laminate 100, while the water-guiding structure of the short side 720 of the photovoltaic frame 700 is one or more second water-guiding notches 721 provided on the horizontal portion of the short side 720. Figure 19 As shown, there are three drainage channels. The second drainage notch 721 and the upper surface 110 of the photovoltaic laminate 100 enclose each other to form a drainage channel extending from the upper surface 110 of the photovoltaic laminate 100 to the outside of the short side 720. In this way, drainage can be achieved through the drainage channel 250 to the long side 710 of the photovoltaic module, and drainage can be achieved through the second drainage notch 721 to the short side 720 of the photovoltaic module, ensuring the overall drainage effect.
