Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic technology, and in particular to photovoltaic modules and their frame structures. Background Technology
[0002] With the development of the photovoltaic industry, large-scale ground-mounted power stations are becoming increasingly common, while prime land resources for photovoltaic power station construction are dwindling. Furthermore, with the advancement of green building policies and related standards in recent years, various regions have introduced subsidy policies for building-integrated photovoltaics (BIPV), making rooftop power stations increasingly popular. BIPV refers to the simultaneous design, construction, and commissioning of rooftop power stations with the building itself, making the rooftop power station an integral part of the building and less likely to damage the roof's waterproofing, insulation, and heat insulation structures.
[0003] The frames of existing photovoltaic module products on the market generally use either a drainage channel structure that only drains water or a waterproof sealing strip structure that only waterproofs. The former only drains water and does not waterproof, and the drainage channel is relatively wide, thus affecting the efficiency of the module; the latter only waterproofs and does not drain water, so if there is any improper construction during installation, such as the waterproof strip failing to form an effective seal or the strip aging and reducing its waterproofing ability, it will lead to roof leaks. Utility Model Content
[0004] Based on this, it is necessary to address the existing technologies that generally use drainage channel structures for the frame that only have drainage functions, which only drain water and do not waterproof. The drainage channels are also made quite wide, thus affecting the efficiency of the module. Alternatively, there are waterproof sealing strip structures that only have waterproof functions, which only waterproof and do not drain water. If there is any improper construction during installation, such as the waterproof strip failing to form an effective seal or aging of the strip reducing its waterproofing ability, it will lead to roof leakage. Therefore, it is necessary to provide a photovoltaic module and its frame structure.
[0005] A frame structure for a photovoltaic module, used to clamp adjacent first and second photovoltaic panels, the frame structure of the photovoltaic module comprising:
[0006] The first clamping frame includes a first clamping member and a first snap-fit member connected to each other. The first clamping member is used to clamp the side of the first photovoltaic panel that is close to the second photovoltaic panel.
[0007] The second clamping frame includes a second clamping member and a second snap-fit member connected to each other. The second clamping member is used to clamp the side of the second photovoltaic panel close to the first photovoltaic panel.
[0008] A sealing strip, the two sides of which respectively abut against the first clamping member and the second snap-fit member, so that the second snap-fit member abuts against the first snap-fit member.
[0009] In the process of installing and fixing the first and second photovoltaic panels, the frame structure of the aforementioned photovoltaic module first clamps the first photovoltaic panel with a first clamping member. Then, one side of the sealing strip abuts against the first clamping member, and the other side abuts against the second snap-fit member, so that the second snap-fit member abuts against the first snap-fit member. Then, the second clamping member clamps one side of the second photovoltaic panel, thereby clamping and fixing the adjacent first and second photovoltaic panels. Along the extension direction of the first photovoltaic panel, multiple photovoltaic panels can be clamped by the frame structure of multiple photovoltaic modules to form a photovoltaic array. The two sides of the sealing strip abut against the first clamping member and the second snap-fit member respectively, so that the second snap-fit member abuts against the first snap-fit member. Therefore, the sealing strip can seal the gap between the first photovoltaic panel and the second photovoltaic panel, that is, the gap between the first clamping frame and the second clamping frame. At the same time, it ensures that the first snap-fit member and the second snap-fit member are directly and stably snapped together. Since there is only a gap between the first photovoltaic panel and the second photovoltaic panel, even if liquids such as wastewater and rainwater enter the frame structure of the photovoltaic module through the sealing strip, they can be discharged from the space between the first snap-fit member and the second snap-fit member.
[0010] In one embodiment, the first snap-fit member includes a mounting portion and a first snap-fit portion;
[0011] The mounting part is connected to the first clamping member and protrudes toward the first clamping member, the first snap-fit part is connected to the first clamping member, and one side of the sealing strip is connected to the mounting part;
[0012] One side of the second snap-fit member abuts against the first snap-fit part, and the other side abuts against the side of the sealing strip opposite to the mounting part.
[0013] In one embodiment, the mounting part has a mounting groove, and the groove opening has a first constriction structure;
[0014] The sealing strip includes a parallel and connected snap-fit strip and an abutment strip. The snap-fit strip snaps between the first constriction structure and the groove wall of the mounting groove. The side of the abutment strip opposite to the snap-fit strip abuts against the side of the second snap-fit member opposite to the first snap-fit part.
[0015] In one embodiment, the second snap-fit member includes a protrusion and a second snap-fit portion;
[0016] The second snap-fit portion is connected to the second clamping member, the protrusion is connected to the side of the second snap-fit portion near the second photovoltaic panel, the protrusion abuts against the first snap-fit portion, and the abutting strip abuts against the side of the second snap-fit portion away from the protrusion.
[0017] In one embodiment, the protrusion has a receiving groove on the side facing the first snap-fit portion, and the groove opening has a second constriction structure, which abuts against the first snap-fit portion.
[0018] In one embodiment, the frame structure of the photovoltaic module further includes a waterproof strip that passes through the receiving groove.
[0019] In one embodiment, the first snap-fit portion is further provided with an abutting protrusion, and the protrusion abuts against the abutting protrusion.
[0020] In one embodiment, along a direction perpendicular to the first photovoltaic panel, the second snap-fit portion is inserted between the first snap-fit portion and the first clamping member, and along the direction in which the second snap-fit portion is inserted, the distance between the abutment protrusion and the first clamping member gradually decreases.
[0021] In one embodiment, the abutting protrusion has an abutting plane, and the protrusion abuts against the abutting plane.
[0022] In one embodiment, the first snap-fit portion includes a first extension portion and a first insertion portion connected together, and the second snap-fit portion includes a second extension portion and a second insertion portion connected together;
[0023] The first extension and the second extension extend in a first direction, and the first insertion part and the second insertion part in a second direction; the first extension is connected to the first clamping member, the second extension is connected to the second clamping member, the mounting part is connected to the first insertion part and protrudes toward the first insertion part, the protruding part is connected to the side of the second insertion part near the second photovoltaic panel, the first insertion part is inserted between the second insertion part and the second clamping member, and the second insertion part is inserted between the first insertion part and the first clamping member;
[0024] The first direction is perpendicular to the second direction, and the second direction is perpendicular to the first photovoltaic panel.
[0025] One embodiment of this application provides a photovoltaic module, the photovoltaic module comprising: a first photovoltaic panel, a second photovoltaic panel, and a frame structure of the photovoltaic module;
[0026] The first clamping member is used to clamp the side of the first photovoltaic panel that is close to the second photovoltaic panel;
[0027] The second clamping member is used to clamp the side of the second photovoltaic panel that is close to the first photovoltaic panel.
[0028] During the installation and fixing process of the photovoltaic module, the first clamping member first clamps the first photovoltaic panel. Then, one side of the sealing strip abuts against the first clamping member, and the other side abuts against the second snap-fit member so that the second snap-fit member abuts against the first snap-fit member. Then, the second clamping member clamps one side of the second photovoltaic panel, thereby clamping and fixing the adjacent first photovoltaic panel and second photovoltaic panel. Along the extension direction of the first photovoltaic panel, multiple photovoltaic panels can be clamped by the frame structure of multiple photovoltaic modules to form a photovoltaic array. The two sides of the sealing strip abut against the first clamping member and the second snap-fit member respectively, so that the second snap-fit member abuts against the first snap-fit member. Therefore, the sealing strip can seal the gap between the first photovoltaic panel and the second photovoltaic panel, that is, the gap between the first clamping frame and the second clamping frame. At the same time, it ensures that the first snap-fit member and the second snap-fit member are directly and stably snapped together. Since there is only a gap between the first photovoltaic panel and the second photovoltaic panel, even if liquids such as wastewater and rainwater enter the frame structure of the photovoltaic module through the sealing strip, they can be discharged from the space between the first snap-fit member and the second snap-fit member.

[0044] See Figure 1 , Figure 1 A schematic diagram of a photovoltaic module frame structure 10 clamping adjacent first photovoltaic panels 21 and second photovoltaic panels 22 is shown in one embodiment. The photovoltaic module frame structure 10 provided in one embodiment of this application includes: a first clamping frame 100, a second clamping frame 200, and a sealing strip 300.
[0045] See Figure 1 and Figure 2 In the aforementioned photovoltaic module frame structure 10, the first clamping frame 100 includes a first clamping member 110 and a first snap-fit member 120 connected together. The first clamping member 110 is used to clamp the side of the first photovoltaic panel 21 near the second photovoltaic panel 22. The second clamping frame 200 includes a second clamping member 210 and a second snap-fit member 220 connected together. The second clamping member 210 is used to clamp the side of the second photovoltaic panel 22 near the first photovoltaic panel 21. The two sides of the sealing strip 300 abut against the first clamping member 110 and the second snap-fit member 220 respectively, so that the second snap-fit member 220 abuts against the first snap-fit member 120. Both the first clamping frame 100 and the second clamping frame 200 are strip frames, extending in the direction of the edges of the first photovoltaic panel 21 and the second photovoltaic panel 22.
[0046] In the process of installing and fixing the first photovoltaic panel 21 and the second photovoltaic panel 22, the frame structure 10 of the photovoltaic module first clamps the first photovoltaic panel 21 with the first clamping member 110. Then, one side of the sealing strip 300 abuts against the first clamping member 110, and the other side abuts against the second snap-fit member 220 so that the second snap-fit member 220 abuts against the first snap-fit member 120. Then, one side of the second photovoltaic panel 22 is clamped by the second clamping member 210, thereby clamping and fixing the adjacent first photovoltaic panel 21 and second photovoltaic panel 22. Along the extension direction of the first photovoltaic panel 21, multiple photovoltaic panels can be clamped by the frame structure 10 of multiple photovoltaic modules to form a photovoltaic array. The two sides of the sealing strip 300 abut against the first clamping member 110 and the second snap-fit member 220 respectively, so that the second snap-fit member 220 abuts against the first snap-fit member 120. Therefore, the sealing strip 300 can seal the gap between the first photovoltaic panel 21 and the second photovoltaic panel 22, that is, the gap between the first clamping frame 100 and the second clamping frame 200. At the same time, it ensures that the first snap-fit member 120 and the second snap-fit member 220 are directly and stably snapped together. Since there is only a gap between the first snap-fit member 120 and the second snap-fit member 220 between the first photovoltaic panel 21 and the second photovoltaic panel 22, even if liquids such as wastewater and rainwater enter the frame structure 10 of the photovoltaic module through the sealing strip 300, they can be discharged from the space between the first snap-fit member 120 and the second snap-fit member 220.
[0047] See Figure 1 and Figure 2 In one embodiment, the first snap-fit member 120 includes a mounting portion 121 and a first snap-fit portion 122. The mounting portion 121 is connected to the first clamping member 110 and protrudes toward the first clamping member 110. The first snap-fit portion 122 is connected to the first clamping member 110, and one side of the sealing strip 300 is connected to the mounting portion 121. One side of the second snap-fit member 220 abuts against the first snap-fit portion 122, and the other side abuts against the side of the sealing strip 300 away from the mounting portion 121. Thus, one side of the sealing strip 300 is fixed by the mounting portion 121. When the first snap-fit member 120 and the second snap-fit member 220 snap-fit together through sliding or other actions, the second snap-fit member 220 abuts against the sealing strip 300 until the second snap-fit member 220 and the first snap-fit member 120 are snapped into place. During this process, the sealing strip 300 can elastically deform in a direction perpendicular to its length.
[0048] See Figure 1 and Figure 2In one embodiment, the mounting portion 121 has a mounting groove 123, the groove opening of which has a first constriction structure 124. The sealing strip 300 includes a parallel and connected snap-fit strip 310 and an abutment strip 320. The snap-fit strip 310 snaps between the first constriction structure 124 and the groove wall of the mounting groove 123, and the abutment strip 320 abuts against the side of the second snap-fit member 220 opposite to the snap-fit strip 310. The snap-fit strip 310 snaps between the groove walls of the first constriction structure 124 and the mounting groove 123 to fix the sealing strip 300 to the mounting portion 121, and the abutment strip 320 abuts against the second snap-fit member 222 through deformation.
[0049] Specifically, the snap-fit strip 310 is sheet-shaped, the abutment strip 320 is sheet-shaped, the interface of the sealing strip 300 forms a T-shape, the snap-fit strip 310 is located between the first constriction structure 124 and the groove wall of the mounting groove 123, and the abutment strip 320 extends out of the first constriction structure 124 and abuts against the second snap-fit part 222.
[0050] Preferably, the abutment strip 320 has a gradually decreasing thickness in the direction away from the snap-fit strip 310, so as to facilitate the elastic deformation of the abutment strip 320 and its contact with the second snap-fit portion 222.
[0051] In other embodiments, the snap-fit strip 310 is columnar, the mounting groove 123 is an arc-shaped groove, the snap-fit strip 310 is located between the mounting groove 123 and the first constriction structure 124, and the abutment strip 320 is sheet-shaped and extends out of the first constriction structure 124.
[0052] See Figure 1 and Figure 2 In one embodiment, the second latching member 220 includes a protrusion 221 and a second latching member 222. The second latching member 222 is connected to the second clamping member 210, the protrusion 221 is connected to the side of the second latching member 222 near the second photovoltaic panel 22, the protrusion 221 abuts against the first latching member 122, and the abutting strip 320 abuts against the side of the second latching member 222 opposite to the protrusion 221. By providing the protrusion 221, the second latching member 220 can abut more tightly against the first latching member 120.
[0053] See Figure 1 and Figure 2 In one embodiment, the protrusion 221 has a receiving groove 223 on the side facing the first snap-fit portion 122. The groove of the receiving groove 223 has a second narrowing structure 224. The second narrowing structure 224 abuts against the first snap-fit portion 122. This structure can reduce the material used while ensuring the abutment force of the protrusion 221, thereby making the frame structure 10 of the photovoltaic module lighter.
[0054] In one embodiment, the frame structure 10 of the photovoltaic module also includes a waterproof strip (not shown). The waterproof strip passes through the receiving groove 223, thereby sealing the gap between the protrusion 221 and the first snap-fit portion 122. Thus, the sealing strip 300 and the waterproof strip are used to seal the two snap-fit gaps, thereby improving the waterproof effect.
[0055] See Figure 1 and Figure 2 In one embodiment, the first snap-fit portion 122 is further provided with an abutment protrusion 125, and the protrusion 221 abuts against the abutment protrusion 125, thereby making the abutment between the first snap-fit portion 122 and the second snap-fit portion 222 more tightly through the abutment protrusion 125.
[0056] See Figure 1 and Figure 2 In one embodiment, along a direction perpendicular to the first photovoltaic panel 21, the second latching portion 222 is inserted between the first latching portion 122 and the first clamping member 110. Along the insertion direction of the second latching portion 222, the distance between the abutting protrusion 125 and the first clamping member 110 gradually decreases. Thus, when the second latching portion 222 is inserted between the first latching portion 122 and the first clamping member 110, the second latching portion 222 can be stably inserted by the larger distance between the abutting protrusion 125 and the first clamping member 110, and the force during the insertion process gradually increases, thereby improving the abutting effect.
[0057] See Figure 1 and Figure 2 In one embodiment, the abutment protrusion 125 has an abutment plane 126, and the protrusion 221 abuts against the abutment plane 126, making the abutment between the protrusion 221 and the first snap-fit portion 122 more stable.
[0058] See Figure 1 and Figure 2In one embodiment, the first latching portion 122 includes a first extension portion 127 and a first insertion portion 128 connected together, and the second latching portion 222 includes a second extension portion 225 and a second insertion portion 226 connected together. The extension directions of the first extension portion 127 and the second extension portion 225 are a first direction, and the extension directions of the first insertion portion 128 and the second insertion portion 226 are a second direction. The first extension portion 127 is connected to the first clamping member 110, the second extension portion 225 is connected to the second clamping member 210, the mounting portion 121 is connected to the first insertion portion 128 and protrudes toward the first insertion portion 128, the protrusion 221 is connected to the side of the second insertion portion 226 near the second photovoltaic panel 22, the first insertion portion 128 is inserted between the second insertion portion 226 and the second clamping member 210, and the second insertion portion 226 is inserted between the first insertion portion 128 and the first clamping member 110. The first direction is perpendicular to the second direction, and the second direction is perpendicular to the first photovoltaic panel 21.
[0059] In this embodiment, the first clamping member 110, the first extension 127, and the first insertion part 128 form a hook structure with a square cross-sectional profile, and the second clamping member 210, the second extension 225, and the second insertion part 226 form a hook structure with a square cross-sectional profile. The two hook structures are inserted into and engaged with each other. At the same time, the sealing strip 300, the protrusion 221, and the mounting part 121 improve the tightness of the engagement after insertion and engagement, making the engagement more stable.
[0060] In other embodiments, one side of the sealing strip 300 abuts against the first support frame 130 and the other side abuts against the second insertion part 226. Thus, by setting the first support frame 130, the sealing strip 300 can penetrate deep into the drainage groove 120a, away from the light-receiving surface of the first photovoltaic panel 21 and the first clamping member 110, thereby improving aesthetics.
[0061] Specifically, the first clamping frame 100 further includes a first support frame 130, and the second clamping frame 200 further includes a second support frame 230. The first support frame 130 is connected to the end of the first clamping member 110 near the inner side of the first photovoltaic panel 21, and the second support frame 230 is connected to the end of the second clamping member 210 near the inner side of the second photovoltaic panel 22. The first extension 127 is connected to the end of the first support frame 130 away from the first clamping member 110, the mounting part 121 is connected to the side of the first clamping member 110 away from the first photovoltaic panel 21, and the second extension 225 is connected to the side of the second clamping member 210 away from the second photovoltaic panel 22. The second insertion part 226 is inserted into the drainage groove 120a formed between the first insertion part 128, the first extension part 127 and the first support frame 130. If rainwater or wastewater passes through the gap between the sealing strip 300 and the second insertion part 226, it will enter the drainage groove 120a and be discharged from the frame structure 10 of the photovoltaic module along the extension direction of the drainage groove 120a.
[0062] Specifically, the sealing strip 300 undergoes elastic deformation along the second direction. After bending, when looking at the photovoltaic panel, the sealing strip 300 is only visible through a tiny gap between the mounting part 121 and the second insertion part 226. The sealing strip 300 is hidden under the visible surface, which only shows the glass of the photovoltaic panel and the aluminum alloy frame of the photovoltaic module's frame structure 10, resulting in a relatively good appearance. Simultaneously, the size of the drainage channel 120a is much smaller than that of the drainage channel 120a in existing technologies that only have a drainage structure, improving module efficiency. Both the sealing strip 300 and the waterproof strip are inserted from one end along the length of the photovoltaic module's frame structure 10, and both ends of the sealing strip 300 and the waterproof strip can be connected to the first snap-fit member 120 and the second snap-fit member 220 using adhesive.
[0063] Specifically, a frame adhesive 400 is provided between the first clamping member 110 and the first photovoltaic panel 21, and a frame adhesive 400 is provided between the second clamping member 210 and the second photovoltaic panel 22, so as to stably clamp the first photovoltaic panel 21 and the second photovoltaic panel 22.
[0064] See Figure 1 and Figure 2 One embodiment of this application provides a photovoltaic module 20, which includes a first photovoltaic panel 21, a second photovoltaic panel 22, and a frame structure 10. A first clamping member 110 is used to clamp the side of the first photovoltaic panel 21 closest to the second photovoltaic panel 22. A second clamping member 210 is used to clamp the side of the second photovoltaic panel 22 closest to the first photovoltaic panel 21.
[0065] In the process of the photovoltaic module 20 described above, the first clamping member 110 clamps the first photovoltaic panel 21. Then, one side of the sealing strip 300 abuts against the first clamping member 110, and the other side abuts against the second snap-fit member 220 so that the second snap-fit member 220 abuts against the first snap-fit member 120. Then, the second clamping member 210 clamps one side of the second photovoltaic panel 22, thereby clamping and fixing the adjacent first photovoltaic panel 21 and second photovoltaic panel 22. Along the extension direction of the first photovoltaic panel 21, multiple photovoltaic panels can be clamped by the frame structure 10 of multiple photovoltaic modules to form a photovoltaic array. The two sides of the sealing strip 300 abut against the first clamping member 110 and the second snap-fit member 220 respectively, so that the second snap-fit member 220 abuts against the first snap-fit member 120. Therefore, the sealing strip 300 can seal the gap between the first photovoltaic panel 21 and the second photovoltaic panel 22, that is, the gap between the first clamping frame 100 and the second clamping frame 200. At the same time, it ensures that the first snap-fit member 120 and the second snap-fit member 220 are directly and stably snapped together. Since there is only a gap between the first snap-fit member 120 and the second snap-fit member 220 between the first photovoltaic panel 21 and the second photovoltaic panel 22, even if liquids such as wastewater and rainwater enter the frame structure 10 of the photovoltaic module through the sealing strip 300, they can be discharged from the space between the first snap-fit member 120 and the second snap-fit member 220.
[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
