Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic module frame structure, specifically relating to a photovoltaic module frame structure with an extremely small A-side. Background Technology

[0002] Photovoltaic modules are composed of main materials such as aluminum frames, glass, encapsulant film, and cells. The frame serves as the outer edge protection for the module's laminates (mainly glass), protecting both the module and the installers. Individual laminates are typically 4.5-5.2mm thick and lack sufficient strength on their own. The aluminum alloy frame is used to strengthen the overall mechanical strength of the module. As a power generation device, the photovoltaic module carries its own voltage and current. In the event of accidental leakage current, it needs to act as a conductive intermediate connection to ground, protecting the equipment and personnel safety.

[0003] Different photovoltaic module applications and design requirements may necessitate varying adhesive filler amounts to ensure sealing and bonding performance. Existing frame structures struggle to flexibly adjust to changes in adhesive volume, easily leading to overfilling or underfilling. Excessive adhesive results in waste, increased costs, and potential overflow affecting module appearance; insufficient adhesive leads to poor sealing and bonding, reducing module stability and lifespan. This innovative design precisely controls the gap between the adhesive overflow and storage tanks and the laminate by adjusting the position of the limiting protrusions, achieving accurate adhesive volume matching and ensuring uniform and appropriate adhesive filling. This solves the problem of adhesive volume matching in existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic module frame structure with an extremely small A-side, addressing the issue that different photovoltaic module application scenarios and design requirements may require varying amounts of adhesive to ensure the module's sealing and bonding performance. Existing frame structures are difficult to adjust flexibly according to changes in adhesive volume, easily resulting in either too much or too little adhesive. Excessive adhesive leads to waste, increased costs, and potential overflow affecting the module's appearance; insufficient adhesive results in poor sealing and bonding, reducing module stability and lifespan.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module frame structure with an extremely small A-side, including a frame body, a B-side block disposed at the upper left inner position of the frame body, and a small A-side block disposed at the upper right position of the B-side block;

[0006] The cavity on the right side of the B-side block is an overflow groove, and a glue storage groove is recessed at the lower right side of the B-side block.

[0007] An adjustment groove is provided on the inner left side of the small A-block, and an insert plate is provided on the inner side of the adjustment groove. An adjustment bolt is provided in the adjustment groove on the upper side of the insert plate, and a limit protrusion is provided on the lower side of the insert plate.

[0008] Preferably, the adjusting bolt is connected to the small A-block via a threaded connection, and the adjusting bolt moves up and down within the small A-block.

[0009] Preferably, the insert plate and the limiting protrusion are fixedly connected, and the insert plate is connected to the slot through an insertion connection method.

[0010] Preferably, the end of the adjusting bolt is connected to the insert plate via a sleeve connection, and the adjusting bolt can rotate within the insert plate.

[0011] Preferably, the limiting protrusion is hemispherical in shape and can move up and down within the slot.

[0012] Preferably, a first lamination support platform is formed on the lower right side of the small A-block, and a second lamination support platform is formed on the outer sides of both sides of the glue storage tank.

[0013] Preferably, the first laminate support platform and the second laminate support platform are provided with a laminate body, and the gap cavity between the laminate body, the overflow tank and the storage tank is filled with glue body.

[0014] Compared with the prior art, this utility model provides a photovoltaic module frame structure with an extremely small A-side, which has the following beneficial effects:

[0015] 1. When producing photovoltaic modules of different specifications, users only need to adjust the position of the limiting protrusion by adjusting the bolts to adapt to different glass thicknesses and different glue usage requirements. There is no need to design and manufacture frame molds separately for each specification, greatly reducing mold costs and mold changeover time. This allows the production line to quickly switch between producing different specifications, improving production efficiency and flexibility.

[0016] Traditional photovoltaic module frames often require complex processing techniques or additional adjustment steps to accommodate different glass sizes. This adjustable limiting protrusion structure, however, allows for simple bolt adjustments, reducing the operational difficulty and skill requirements of workers during production and improving the stability of production quality.

[0017] 2. Precisely adjustable limiting protrusions ensure the accurate positioning of the laminate within the frame, resulting in more even stress distribution across the module. During long-term use, especially under external forces such as wind and vibration, this effectively reduces lamination displacement and swaying, enhancing the overall stability of the photovoltaic module and lowering the risk of failure due to loose components.

[0018] By adjusting the position of the limiting protrusions, the size of the gap between the overflow tank and the glue reservoir and the laminate can be precisely controlled, thereby achieving uniform glue filling. This helps improve the sealing performance of the module, preventing moisture, dust, and other impurities from entering the module, protecting the internal circuitry and structure, and extending the lifespan of the photovoltaic module.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-5 The photovoltaic module frame structure with a very small A-side shown includes a frame body 7, a B-side block 1 located at the upper left inner position of the frame body 7, and a small A-side block 3 located at the upper right position of the B-side block 1.

[0027] The cavity on the right side of B-side 1 is an overflow groove 2, and a glue storage groove 6 is recessed at the lower right side of B-side 1.

[0028] An adjustment groove 12 is provided on the left inner side of the small A-face block 3. An insert plate 10 is provided on the inner side of the adjustment groove 12. An adjustment bolt 11 is provided in the adjustment groove 12 on the upper side of the insert plate 10. A limit protrusion 4 is provided on the lower side of the insert plate 10.

[0029] In this embodiment, the user applies glue to the entire frame in the area between the frame B-side block 1 and the second laminate support platform 13 to prepare for subsequent assembly and sealing.

[0030] Place the laminate body 8 face down on the equipment, and place the four small A-side blocks 3 of the frame face down on the same plane, so that the glass groove of the frame is precisely aligned with the laminate body 8, ensuring that the inner plane of the small A-side block 3 is basically on the same plane as the front of the glass. Then, move the frame inward to assemble. When the side of the laminate body 8 contacts the limiting protrusion of the small A-side block 3, the frame movement is completed. At this time, the edge of the front of the glass of the laminate body 8 directly contacts and supports the inner plane of the small A-side block 3.

[0031] During assembly, the silicone flows in two directions under the pressure of the laminate body 8. In direction 1, the silicone moves along the B-side block 1 towards the overflow groove 2. Since the vertical surface of the laminate body 8 and the B-side block 1 form an enlarged angle, it facilitates the rapid overflow of the silicone, which finally stops at the junction of the protrusion and the laminate body 8, completing the silicone filling of this area.

[0032] In direction 2, the silicone moves outward along the horizontal channel between the back glass of the laminate body 8 and the second laminate support platform 13, first filling the silicone reservoir 6, and then continuing to flow outward until the silicone overflows visibly, ensuring that the internal silicone is completely filled, at which point the assembly is complete.

[0033] The assembled components are cured. After curing, the first laminate support platform 5 of the frame body 7 has no silicone contact with the front of the glass, while the second laminate support platform 13 forms a silicone layer with a thickness of ≥2mm with the back of the glass, enhancing the stability and sealing of the component. At the same time, to further enhance the silicone bonding strength, a silicone layer with a depth of 0.5mm is also stored inside the glue storage tank 6 of the frame, and the sides of the B-side block 1 and the laminate body 8 are also completely filled with silicone.

[0034] like Figure 1-5As shown, the adjusting bolt 11 is connected to the small A-side block 3 by a threaded connection, and the adjusting bolt 11 can move up and down within the small A-side block 3. The insert plate 10 and the limiting protrusion 4 are fixedly connected. The insert plate 10 is connected to the slot by an insert connection. The end of the adjusting bolt 11 is connected to the insert plate 10 by a sleeve connection. The adjusting bolt 11 can rotate within the insert plate 10. The limiting protrusion 4 is hemispherical in shape and can move up and down within the slot. A first laminate support platform 5 is formed on the lower right side of the small A-side block 3. A second laminate support platform 13 is formed on both sides of the glue storage tank 6. A laminate body 8 is provided inside the first laminate support platform 5 and the second laminate support platform 13. The gap cavity between the laminate body 8, the overflow trough 2, and the glue storage tank 6 is filled with glue body 9.

[0035] Preferably, the user places the laminate body 8 on the first laminate support platform 5 and the second laminate support platform 13. The first laminate support platform 5 and the second laminate support platform 13 provide stable support for the laminate body 8, ensuring its accurate positioning within the frame body 7.

[0036] After the laminate body 8 is placed, the glue body 9 is filled into the gaps and cavities between the glue overflow tank 2, the glue storage tank 6, and the laminate body 8. The position adjustment of the limiting protrusion 4 can precisely control the size of these gaps, thereby ensuring the uniformity and appropriate amount of glue filling. For example, when the limiting protrusion 4 is lower, the gap is relatively small, suitable for filling less glue; when the limiting protrusion 4 is higher, the gap is larger, which can accommodate more glue to meet different sealing and bonding requirements.

[0037] Preferably, the user rotates the adjusting bolt 11 using a tool (such as a screwdriver). Since the adjusting bolt 11 is connected to the small A-side block 3 via a threaded connection, according to the principle of threaded transmission, when the adjusting bolt 11 is rotated, it will move up and down within the small A-side block 3.

[0038] The end of the adjusting bolt 11 is connected to the insert plate 10 via a sleeve connection, and the adjusting bolt 11 can rotate within the insert plate 10. When the adjusting bolt 11 moves up and down, it will drive the insert plate 10 connected to it to move within the adjusting groove 12. Because the insert plate 10 and the limiting protrusion 4 are fixedly connected, the movement of the insert plate 10 will directly drive the limiting protrusion 4 to move, thereby realizing the adjustment of the position of the limiting protrusion 4.

[0039] When faced with glass of different thicknesses (i.e., the laminate body 8) or different adhesive volume requirements, operators can flexibly adjust the position of the limiting protrusion 4. For example, when the glass is thicker, the adjusting bolt 11 is turned upwards, causing the limiting protrusion 4 to move upwards, leaving enough space for the glass; when more adhesive volume is required, the position of the limiting protrusion 4 can also be adjusted to adjust the gap size between the overflow groove 2 and the adhesive storage groove 6 and the laminate body 8 to meet the adhesive filling requirements.

[0040] Optionally, the limiting protrusion 4 is hemispherical. This shape provides a more uniform pressure distribution when in contact with the laminate body 8, reducing damage to the surface of the laminate body 8. At the same time, the hemispherical shape reduces friction between the adjustment groove 12 and the laminate body 8 during movement, making the adjustment process smoother.

[0041] Optionally, the limiting protrusion 4 can move up and down within the slot, precisely controlling the position of the laminate body 8 within the frame body 7 as needed. During the framing process, when the laminate body 8 moves towards the frame slot, the limiting protrusion 4 can accurately limit its movement, ensuring the accuracy and stability of the framing.

[0042] Optionally, the insert plate 10 is connected to the adjusting groove 12 via an insert connection. This connection method ensures the stability of the insert plate 10 during movement, preventing it from shaking or shifting. At the same time, the threaded connection between the adjusting bolt 11 and the small A-side block 3, as well as the sleeve connection with the insert plate 10, further enhances the stability of the entire adjusting structure, ensuring that it will not loosen during long-term use.

[0043] Optionally, by adjusting the position of the limiting protrusion 4, this frame structure can adapt to various specifications of laminate body 8 and adhesive filling requirements. Regardless of the glass thickness or the type and amount of adhesive, the best assembly effect can be achieved through simple adjustments, improving the versatility and applicability of the photovoltaic module frame.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
