Photovoltaic module frame and photovoltaic module

Abstract

The application discloses a photovoltaic module frame and a photovoltaic module, and belongs to the technical field of photovoltaic technology. The photovoltaic module frame comprises a supporting piece, a limiting piece and a buffer piece. The limiting piece is connected to one side of the supporting piece along a first direction, and the limiting piece and the supporting piece enclose a containing space. The buffer piece is arranged inside the containing space and connected with the supporting piece, and abuts between the edge of a photovoltaic laminated piece and the limiting piece. When extrusion force applied by a framing machine during framing causes the photovoltaic laminated piece and the limiting piece to extrude each other, or when the photovoltaic module is deformed due to external force during use in a power station, causing the photovoltaic laminated piece and the limiting piece to extrude each other, the buffer piece will first bear force and deform, thereby absorbing part of the extrusion force through the deformation, avoiding hard contact between the photovoltaic laminated piece and the limiting piece, thereby reducing the risk of burst of the photovoltaic laminated piece caused by extrusion, and ensuring the structural integrity and service life of the photovoltaic module.

Technical Field

[0001] This application belongs to the field of photovoltaic technology, specifically relating to a photovoltaic module frame and a photovoltaic module. Background Technology

[0002] In the photovoltaic (PV) industry, PV modules are assembled by pressing PV laminates onto the module frame using a framing machine, with the PV laminates abutting against the sides of the module frame. During the framing process and long-term use of the power plant, the edges of the PV laminates are prone to being pushed and broken by the module frame. Utility Model Content

[0003] The purpose of this utility model is to provide a photovoltaic module frame to solve the technical problem that the edges of photovoltaic laminates are easily popped off by the frame; another purpose of this application is to provide a photovoltaic module.

[0004] Technical solution: This application provides a photovoltaic module frame, including: Support components; A limiting member is connected to one side of the support member along the first direction and forms an accommodating space with the support member; A buffer is disposed within the accommodating space and connected to the support.

[0005] In some embodiments, the limiting member has a slot formed on the side of the limiting member facing the receiving space; The buffer includes: The buffer section protrudes from the limiting member; The protrusion is entirely housed within the slot.

[0006] In some embodiments, in the second direction, the minimum size of the card slot is H1 and the maximum size is H2, with the minimum size H1 of the card slot located on the side of the maximum size H2 of the card slot closer to the accommodating space; In the second direction, the maximum size of the protrusion is H3 and the minimum size is H4, and the minimum size H4 of the protrusion is located on the side of the maximum size H3 of the protrusion closer to the buffer portion; The following conditions must be met: H1 < H2, H4 < H3, and H1 < H3; the second direction intersects the first direction.

[0007] In some embodiments, in the second direction, the maximum size H2 of the slot and the maximum size H3 of the protrusion satisfy: H2≤H3.

[0008] In some embodiments, the limiting member further includes a first overflow groove, which communicates with the receiving space, and the first overflow groove and the card slot are spaced apart along the first direction.

[0009] In some embodiments, there is a gap between the buffer portion and the support member on the side of the support member closer to the support member.

[0010] In some embodiments, in the second direction, a portion of the buffer extends to cover a portion of the opening of the first overflow groove.

[0011] In some embodiments, a second overflow groove is provided at the end of the support member away from the limiting member, and the second overflow groove, the accommodating space and the first overflow groove are connected.

[0012] In some embodiments, the distance between the side of the buffer portion away from the support member and the support member is greater than or equal to the distance between the side of the limiting member away from the support member and the support member.

[0013] Accordingly, this application also provides a photovoltaic module, comprising: Photovoltaic laminates; As described in any of the above embodiments, the photovoltaic module frame is fitted onto at least one side of the photovoltaic laminate.

[0014] Several embodiments of this application have one of the following beneficial effects: The photovoltaic module frame provided in this application includes a support member, a limiting member, and a buffer member. A photovoltaic laminate is pressed together by a framing machine to connect with the support member, and silicone is filled between the support member and the photovoltaic laminate. The limiting member is connected to one side of the support member along a first direction, and the limiting member and the support member form an accommodating space. When the photovoltaic laminate is placed into the accommodating space, the support member provides stable support for the photovoltaic laminate, and the limiting member further enhances the positioning effect of the photovoltaic laminate by blocking the edge of the laminate, preventing the photovoltaic laminate from shifting during subsequent operation or use. The buffer member is provided. Inside the accommodating space and connected to the support, it abuts against the edge of the photovoltaic laminate and the limiting component. When the framing machine applies pressure during the framing process, causing the photovoltaic laminate and the limiting component to squeeze each other, or when the photovoltaic module is deformed by external forces during power station use, causing the photovoltaic laminate and the limiting component to squeeze, the buffer component will be the first to be stressed and deformed. Through its own deformation, it absorbs part of the extrusion pressure, preventing the photovoltaic laminate from directly contacting the limiting component, thereby reducing the risk of the photovoltaic laminate bursting due to extrusion and ensuring the structural integrity and service life of the photovoltaic module.

[0015] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0023] In some examples, the first direction X is the width direction of the short side frame of the photovoltaic module, and the second direction Y is the height direction of the photovoltaic module.

[0024] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0025] Currently, in the photovoltaic field, photovoltaic modules are assembled by extruding photovoltaic laminates to the module frame using a framing machine. The photovoltaic laminates abut against the sides of the photovoltaic module frame to complete the framing. Due to the accuracy error of the extrusion stroke and the influence of the design dimensions of the photovoltaic module frame, the distance between the front of the photovoltaic module frame and the front of the photovoltaic laminate is generally 0mm to 1.5mm.

[0026] To address the issue of dust accumulation on the underside of photovoltaic (PV) laminates, the short side of the existing PV module frame no longer covers the front of the PV laminate; instead, it is flush with or slightly lower than the front of the PV laminate. The edges of the PV laminate are prone to cracking under external impact. If the edge of the PV laminate is pressed against the short side of the PV module frame during framing, there is a risk of glass breakage. Furthermore, during long-term use in power plants, if the PV module deforms under external forces, the PV laminate may also be punctured by the frame.

[0027] In addition, if there is a large distance between the front of the photovoltaic laminate and the front of the photovoltaic module frame during framing, silicone can easily overflow from the gap between the photovoltaic module frame and the photovoltaic laminate. The silicone will stick to the front of the photovoltaic laminate and the front of the photovoltaic module frame, which is difficult to completely remove and affects the appearance of the photovoltaic module.

[0028] In view of this, embodiments of this application provide a photovoltaic module frame to solve at least part of the above-mentioned technical problems.

[0029] According to the first aspect of this application, please refer to Figure 1 and Figure 5 In this embodiment, the photovoltaic module frame includes a support member 100, a limiting member 200, and a buffer member 400. The support member 100 is a load-bearing component, which is used to support the bottom of the photovoltaic laminate 600 and to provide a working surface for the silicone 500 filling. The limiting member 200 is an edge protection component of the photovoltaic laminate 600, which is set around the edge of the photovoltaic laminate 600 and can simultaneously achieve positioning constraint and edge protection of the photovoltaic laminate 600. The buffer member 400 is an explosion-proof protection component, which can effectively buffer the direct squeezing force between the photovoltaic laminate 600 and the frame, and reduce the explosion rate of the photovoltaic laminate 600 under the action of frame assembly and external forces.

[0030] Specifically, the photovoltaic laminate 600 is pressed by the framing machine to connect with the support 100. The space between the support 100 and the photovoltaic laminate 600 is filled with silicone 500. After the silicone 500 cures, a stable adhesive structure is formed, thereby achieving a reliable connection between the photovoltaic laminate 600 and the support 100.

[0031] A limiting member 200 is connected to one side of the support member 100 along the first direction X, and the limiting member 200 and the support member 100 form an accommodating space 300. The size of the accommodating space 300 is adapted to the photovoltaic laminate 600 and is used to accommodate the photovoltaic laminate 600. When the photovoltaic laminate 600 is placed in the accommodating space 300, the support member 100 can stably support the photovoltaic laminate 600, and the limiting member 200 can further enhance the positioning effect of the photovoltaic laminate 600 by blocking the edge of the laminate, thus preventing the photovoltaic laminate 600 from shifting during subsequent operation or use.

[0032] The buffer 400 is disposed inside the accommodating space 300 and connected to the support 100, and abuts against the edge of the photovoltaic laminate 600 and the limiting member 200. When the extrusion force applied by the framing machine during the framing process causes the photovoltaic laminate 600 and the limiting member 200 to squeeze each other, or when the photovoltaic module is deformed by external forces during the use of the power station, causing the photovoltaic laminate 600 and the limiting member 200 to squeeze each other, the buffer 400 will be the first to be subjected to force and deform. Through its own deformation, it absorbs part of the extrusion force, preventing the photovoltaic laminate 600 from making direct hard contact with the limiting member 200, thereby reducing the risk of the photovoltaic laminate 600 bursting due to extrusion and ensuring the structural integrity and service life of the photovoltaic module.

[0033] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The limiting member 200 has a slot 210, which is formed on the side of the limiting member 200 facing the receiving space 300. The buffer member 400 includes a buffer portion 410 and a protrusion 420 connected to each other, and the buffer portion 410 and the protrusion 420 are integral structures. The buffer portion 410 protrudes from the limiting member 200, that is, the buffer portion 410 is located on the side of the limiting member 200 facing the receiving space 300, and can abut against the edge of the photovoltaic laminate 600; the protrusion 420 protrudes from the side of the buffer portion 410 facing the limiting member 200, and the protrusion 420 is entirely received within the slot 210.

[0034] It should be noted that the connection between the buffer part 410 and the limiting member 200 is achieved by the protrusion 420 of the buffer part 400 being accommodated in the slot 210. The protrusion 420 being accommodated in the slot 210 can limit the installation position of the buffer part 400, prevent the buffer part 410 from shifting during the frame assembly process, and thus ensure that the buffer part 410 can fit and abut against the edge of the photovoltaic laminate 600, ensuring the stability of the buffer protection effect.

[0035] In some embodiments, please refer to Figure 3The buffer portion 410 has a dimension L in the first direction X, satisfying 0.5mm ≤ L ≤ 1.5mm. It can be understood that the dimension L of the buffer portion 410 in the first direction X can be any value or a range between any two values ​​from 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, and 1.5mm. The dimension L of the buffer portion 410 in the first direction X ensures that the buffer portion 410 has sufficient deformation space. When the photovoltaic laminate 600 and the limiting member 200 are compressed, it can fully absorb the impact force through its own deformation, preventing damage to the photovoltaic laminate 600 due to hard contact.

[0036] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 In the second direction Y, the slot 210 and the protrusion 420 have the following dimensional relationship: the minimum dimension of the slot 210 is H1 and the maximum dimension is H2. The minimum dimension H1 of the slot 210 is located on the side of the maximum dimension H2 of the slot 210 that is closer to the accommodating space 300. That is, the minimum dimension of the slot 210 facing the buffer part 410 is H1, and the maximum dimension of the slot 210 away from the buffer part 410 is H2. The two satisfy H1 < H2. In other words, the shape of the slot 210 decreases from large to small along the direction of the photovoltaic module frame towards the photovoltaic laminate 600.

[0037] In the second direction Y, the maximum dimension of the protrusion 420 is H3, and the minimum dimension is H4. The minimum dimension H4 of the protrusion 420 is located on the side of the maximum dimension H3 of the protrusion 420 closer to the buffer portion 410. That is, the maximum dimension of the protrusion 420 on the side facing the limiting member 200 is H3, and the minimum dimension of the protrusion 420 on the side away from the limiting member 200 is H4. The two satisfy H4 < H3; that is, the shape of the protrusion 420 decreases from large to small along the direction of the protrusion 420 towards the buffer portion 410. At the same time, the minimum dimension H1 of the slot 210 in the second direction Y and the maximum dimension H3 of the protrusion 420 in the second direction Y must satisfy H1 < H3.

[0038] It should be noted that the slot 210 has a small opening and a large interior; it can be concave or triangular. The protrusion 420 of the buffer component 400 can be inserted into the slot 210. The shape of the protrusion 420 matches the shape of the slot 210 to prevent the buffer component 400 from falling out. Understandably, after the protrusion 420 is accommodated in the slot 210, the larger H3 portion of the protrusion 420 will be engaged with the smaller H1 portion of the slot 210, forming a structural constraint. This effectively prevents the buffer component 400 from falling out of the slot 210 due to vibration, compression, or other external forces during subsequent assembly operations, component transportation, or power plant use. This ensures that the buffer component 400 remains in the preset position, preventing the photovoltaic laminate 600 from losing its buffering function with the limiting component 200 due to displacement of the buffer component 400, thereby reducing the risk of explosion.

[0039] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The maximum dimension H2 of the slot 210 in the second direction Y and the maximum dimension H3 of the protrusion 420 in the second direction Y satisfy H2≤H3. That is, the maximum dimension H3 of the protrusion 420 facing the limiting member 200 will not be less than the maximum dimension H2 of the slot 210 away from the buffer part 410. This means that after the protrusion 420 is inserted into the slot 210, the entire protrusion 420 will form a full fit within the slot 210. This prevents the protrusion 420 from shaking within the slot 210 due to H3 being too small. The matching of H3 and H2 also allows the protrusion 420 to fit tightly against the inner wall of the slot 210, or even form an interference fit. This prevents the buffer part 400 from shifting during photovoltaic module impacts or long-term use, ensuring that the buffer part 410 can always abut against the edge of the photovoltaic laminate 600. Specifically, the dimensional relationship of H2≤H3 can better improve the stability of the connection.

[0040] It should be noted that H3 > H2. The maximum dimension H3 of the protrusion 420 facing the limiting member 200 is only slightly larger than the maximum dimension H2 of the slot 210 away from the buffer part 410. It is necessary to ensure that the protrusion 420 can be installed into the slot 210 if the deformation allows.

[0041] In some embodiments, please refer to Figure 1 and Figure 5The limiting member 200 also has a first overflow groove 220, which communicates with the accommodating space 300. The first overflow groove 220 and the slot 210 are spaced apart along the first direction X. It should be noted that, with the second direction Y as the height direction, the slot 210 and the first overflow groove 220 are distributed vertically. During the bonding process between the support member 100 and the photovoltaic laminate 600, the silicone 500 is compressed, and excess silicone 500 can be stored in the first overflow groove 220, which not only reduces the amount of overflow but also forms a partially stable connection in the first direction X of the photovoltaic laminate 600. In addition, due to the presence of the buffer member 400, the silicone 500 on the side of the photovoltaic laminate 600 facing the limiting member 200 is prevented from overflowing, thus avoiding the silicone 500 from overflowing from the gap between the photovoltaic laminate 600 and the limiting member 200.

[0042] In some embodiments, please refer to Figure 1 , Figure 4 and Figure 5 A gap exists between the buffer portion 410 and the support member 100 on the side near the support member 100, so that the first overflow groove 220 can always be in communication with the receiving space 300. During the assembly of the photovoltaic laminate 600 and the support member 100 and the filling of silicone 500, if the amount of silicone 500 is slightly excessive or it is squeezed and flows, the excess silicone 500 can flow smoothly into the first overflow groove 220 through this gap, without overflowing onto the front of the photovoltaic laminate 600 and / or the front of the photovoltaic module frame (the front of the photovoltaic laminate 600 refers to the side of the photovoltaic laminate 600 away from the support member 100, and the front of the photovoltaic module frame refers to the side of the limiting member 200 away from the support member 100).

[0043] In some embodiments, please refer to Figure 4 and Figure 5 In the second direction Y, a portion of the buffer portion 410 extends to cover a portion of the opening of the first overflow groove 220. This better prevents the silicone 500 from overflowing onto the front of the photovoltaic laminate 600 and / or the front of the photovoltaic module frame. At the same time, the contact area between the photovoltaic laminate 600 and the buffer portion 410 is larger, resulting in a better cushioning effect.

[0044] In some embodiments, please refer to Figure 4 and Figure 5The support member 100 has a second overflow groove 110 at the end away from the limiting member 200. The second overflow groove 110, the accommodating space 300, and the first overflow groove 220 are connected. It should be noted that the side of the support member 100 facing the photovoltaic laminate 600 is pre-coated with silicone 500. When the framing machine presses the photovoltaic laminate 600 against the support member 100, the silicone 500 between the photovoltaic laminate 600 and the support member 100 will flow outwards due to compression, resulting in overflow on both sides of the photovoltaic laminate 600 in the first direction X. Among them, the silicone 500 overflowing from the side of the photovoltaic laminate 600 facing the limiting member 200 in the first direction X will flow into the first overflow groove 220 for storage along the accommodating space 300 and the gap; while the silicone 500 overflowing from the side of the photovoltaic laminate 600 away from the limiting member 200 in the first direction X will flow directly into the second overflow groove 110 at the end of the support member 100. In other words, while avoiding adhesive overflow, it increases the bonding area between the photovoltaic laminate 600 and the photovoltaic module frame, thereby improving the stability and sealing of the structure.

[0045] In some embodiments, please refer to Figure 4 and Figure 5 The distance between the buffer portion 410 and the support member 100 on the side facing away from the support member 100 is greater than or equal to the distance between the limiting member 200 and the support member 100 on the side facing away from the support member 100. It can be understood that, with the second direction Y as the height direction, the buffer portion 410 needs to be flush with the limiting member 200, or the buffer portion 410 needs to be higher than the limiting member 200. This prevents the buffer portion 410 from forming a cavity with the limiting member 200 and the photovoltaic laminate 600. If a cavity is formed, dust and water will accumulate in this cavity.

[0046] It should be noted that the distance between the side of the buffer portion 410 facing away from the support member 100 and the support member 100 is less than or equal to the distance between the side of the photovoltaic laminate 600 facing away from the support member 100 and the support member 100. This means that, with the second direction Y as the height direction, the buffer portion 410 needs to be flush with the photovoltaic laminate 600, or the buffer portion 410 needs to be lower than the photovoltaic laminate 600. This maintains the flatness of the photovoltaic module surface and reduces the risk of dust accumulation.

[0047] Specifically, in the second direction Y, the distance between the side of the buffer portion 410 facing away from the support member 100 and the side of the photovoltaic laminate 600 facing away from the support member 100 ranges from 0 mm to 1.5 mm. It can be understood that the distance between the side of the buffer portion 410 facing away from the support member 100 and the side of the photovoltaic laminate 600 facing away from the support member 100 in the second direction Y can be any value or a range between any two values ​​from 0 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, to 1.5 mm. Furthermore, this distance can be measured using external tools.

[0048] It should be noted that the structural technology of the photovoltaic module frame not described in the above embodiments shown in the accompanying drawings is relatively mature, so this embodiment is not intended to limit it, nor will it be described in detail.

[0049] Accordingly, please refer to Figure 5 The photovoltaic module provided in this application includes the photovoltaic module frame of any of the above embodiments. Therefore, the photovoltaic module can have all the technical features and beneficial effects of the photovoltaic module frame described above, which will not be repeated here.

[0050] It should be noted that the photovoltaic module also includes a photovoltaic laminate 600, and the photovoltaic module frame is fitted onto at least one side of the photovoltaic laminate 600. Specifically, in this embodiment, the photovoltaic module frame consists of the two shorter sides of the photovoltaic module compared to the frames of other photovoltaic modules.
