Technical Field

[0001] This utility model relates to the field of photovoltaic frame technology, specifically to an aluminum frame for photovoltaic modules. Background Technology

[0002] As the global energy landscape shifts towards cleaner and lower-carbon energy, the application of photovoltaic power generation continues to expand. As the core power generation unit, photovoltaic modules are exposed to complex outdoor environments for extended periods. Their structural stability and lifespan directly affect the efficiency of the power generation system. Due to their advantages of being lightweight, high-strength, and corrosion-resistant, aluminum frames have become key components for protecting the edges of photovoltaic modules and enhancing their mechanical load-bearing capacity.

[0003] Traditional aluminum frames for photovoltaic modules are all integrated long strips, which are large in size. Large frames take up a lot of space, have low logistics and loading efficiency, and are easily deformed by collisions. The weight of large frames is concentrated, making them inconvenient to handle manually or mechanically. Especially in outdoor high-altitude installation scenarios, safety and construction efficiency are affected. Therefore, we need to propose an aluminum frame for photovoltaic modules. Utility Model Content

The left and right frames are initially assembled by inserting connecting blocks into connecting slots. The position of the connecting blocks in the connecting slots is positioned by a positioning structure. The upper frame is assembled with slide rail one and slide rail two through a connecting mechanism, thereby avoiding the integrated design of the aluminum frame. The above solution reduces the space occupied by the aluminum frame, improves the logistics loading efficiency of the aluminum frame, provides convenience for manual or mechanical handling, and reduces the impact on safety and construction efficiency in outdoor high-altitude installation scenarios, thus solving the problems mentioned in the background art.

[0023] 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.

[0024] Please see Figure 1-7 This utility model provides a technical solution: an aluminum frame for photovoltaic modules, including a left frame 1, a right frame 2 and a top frame 3. The top of the left frame 1 is provided with a sliding groove 4, and the inner sidewall of the left frame 1 is integrally formed with a connecting block 5. The surface of the connecting block 5 is provided with a positioning structure 6 for positioning the position of the connecting block 5. The top of the right frame 2 is provided with a sliding groove 7, and the position of the sliding groove 7 is aligned with the position of the sliding groove 4. The inner sidewall of the right frame 2 is provided with a connecting groove 8 that is adapted to the connecting block 5. The top frame 3 is L-shaped, and the bottom of the top frame 3 is provided with a connecting mechanism for connecting with the sliding groove 4 and the sliding groove 7.

[0025] During assembly, the left frame 1 is removed and the connecting block 5 is inserted into the connecting groove 8 to initially assemble the left frame 1 with the right frame 2. Then, the positioning structure 6 is used to position the connecting block 5 within the connecting groove 8, aligning the positions of slide 1 4 and slide 2 7, and connecting the inner cavities of slide 1 4 and slide 2 7. Then, the upper frame 3 is removed and assembled with the inner cavities of slide 1 4 and slide 2 7 through the connecting mechanism, combining the upper frame 3 with the left frame 1 and the right frame 2. This avoids the integrated setting of the photovoltaic frame. The above solution reduces the space occupied by the aluminum frame, improves the logistics loading efficiency of the aluminum frame, provides convenience for manual or mechanical handling operations, and reduces the impact on safety and construction efficiency in outdoor high-altitude installation scenarios.

[0026] The positioning structure 6 includes a threaded hole 61 on the surface of the right frame 2 and a positioning hole 62 on the surface of the connecting block 5. The inner cavity of the threaded hole 61 is connected to the inner cavity of the connecting groove 8. The threaded hole 61 and the positioning hole 62 are fixed together by a self-locking bolt. When the left frame 1 and the right frame 2 are spliced, when the connecting block 5 is inserted into the inner cavity of the connecting groove 8, the position of the threaded hole 61 is aligned with the position of the positioning hole 62. The self-locking bolt is connected to the threaded hole 61 and tightened, so that one end of the self-locking bolt is inserted into the inner cavity of the positioning hole 62, thereby positioning the connecting block 5.

[0027] The inner sidewall of the right frame 2 is provided with positioning grooves 9 around its perimeter. Positioning rods 10 are slidably inserted into the inner cavity of the positioning grooves 9. The positioning rods 10 are integrally formed on the inner sidewall of the left frame 1. Through the cooperation of the positioning grooves 9 and the positioning rods 10, the connection between the left frame 1 and the right frame 2 is supported, which improves the stability after the left frame 1 and the right frame 2 are connected and can further improve the splicing accuracy.

[0028] A sealing groove 11 is provided on the inner side wall of the right frame 2. A sealing plate 12 that is adapted to the sealing groove 11 is provided in the inner cavity of the sealing groove 11. The sealing plate 12 is integrally formed on the inner side wall of the left frame 1. The sealing plate 12 is arranged in a square shape and is located inside the four sets of positioning rods 10. When the left frame 1 and the right frame 2 are spliced, the sealing plate 12 is simultaneously inserted into the inner cavity of the sealing groove 11. After the splicing is completed, the sealing plate 12 and the sealing groove 11 are tightly fitted, forming a surrounding sealing barrier at the splicing point of the left frame 1 and the right frame 2, which can effectively prevent outdoor moisture, dust and other impurities from seeping into the interior of the component from the splicing point.

[0029] The connecting mechanism includes a connecting seat 13, the surface of which is slidably connected to the inner cavities of slide groove 1 4 and slide groove 2 7. The connecting seat 13 is I-shaped, and a fixing hole 14 is provided on the surface of the connecting seat 13. A connecting hole 15 is provided at the top of the right frame 2. A positioning pin 16 is inserted and slidably connected to the inner cavity of the connecting hole 15, and the inner cavity of the connecting hole 15 communicates with the inner cavity of slide groove 2 7. One end of the positioning pin 16 engages with the inner cavity of the fixing hole 14. When the upper frame 3 is connected to the left frame 1 and the right frame 2, the I-shaped part at the bottom of the upper frame 3 is first connected. The upper frame 3 is fixed by inserting the connecting seat 13 into the slide groove 7 of the right frame 2 and then sliding it into the inner cavity of the slide groove 4. When it slides to the designated position, the connecting hole 15 is aligned with the fixing hole 14. The positioning pin 16 is inserted into the connecting hole 15 and pushed to engage with the inner cavity of the fixing hole 14 to complete the fixing of the upper frame 3. If the position of the upper frame 3 needs to be adjusted, the positioning pin 16 can be pulled out, and the connecting seat 13 can be slid to the support hole 17 on the inner side wall of the slide groove 7. The positioning pin 16 is inserted into the support hole 17 and engages with the surface of the connecting seat 13 to achieve temporary positioning.

[0030] The inner wall of the second slide 7 is provided with a support hole 17. The support hole 17 is located on the side of the slide away from the connecting hole 15. The inner cavity of the support hole 17 is engaged with the surface of the positioning pin 16. The positioning pin 16 is inserted into the connecting hole 15, passes through the fixing hole 14 and extends into the inner cavity of the support hole 17, so that the support hole 17 supports the other end of the positioning pin 16, which further improves the stability of the connecting seat 13 after it is positioned in the inner cavity of the first slide 4 and the second slide 7.

[0031] This embodiment also includes an internal thread in the inner cavity of the support hole 17 and an external thread on the outer surface of the positioning pin 16. The inner cavity of the support hole 17 is threadedly connected to the outer surface of the positioning pin 16. The threaded connection between the support hole 17 and the positioning pin 16 improves the stability of the positioning pin 16 in the inner cavity of the support hole 17.

[0032] Several sets of drainage channels 18 are evenly spaced at the top of the upper frame 3, and the drainage channels 18 are arc-shaped. When used outdoors, rainwater or condensation water tends to accumulate at the top of the frame. The several sets of arc-shaped drainage channels 18 at the top of the upper frame 3 can use gravity to guide the accumulated liquid to drain quickly along the arc-shaped channels, preventing the liquid from staying on the surface of the upper frame 3 for a long time.

[0033] In practical use: During assembly, take the left frame 1 and insert the connecting block 5 into the connecting groove 8. After the connecting block 5 is inserted into place, align the position of the threaded hole 61 with the position of the positioning hole 62. Connect and tighten the self-locking bolt to the threaded hole 61, so that one end of the self-locking bolt is inserted into the inner cavity of the positioning hole 62 to position the connecting block 5, thus performing preliminary assembly between the left frame 1 and the right frame 2. Take the upper frame 3 and align the I-shaped connecting seat 13 at the bottom of the upper frame 3 with the slide groove 7 of the right frame 2, then slide it into the slide groove 4. When the inner cavity is slid to the designated position, the connecting hole 15 is aligned with the fixing hole 14. The positioning pin 16 is inserted into the connecting hole 15 and extends through the fixing hole 14 to the inner cavity of the support hole 17, thereby realizing the assembly of the upper frame 3, the left frame 1 and the right frame 2. This avoids the integrated setting of the photovoltaic frame. The above solution reduces the space occupied by the aluminum frame, improves the logistics loading efficiency of the aluminum frame, provides convenience for manual or mechanical handling operations, and reduces the impact on safety and construction efficiency in outdoor high-altitude installation scenarios.
