Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a heterojunction lightweight photovoltaic module structure. Background Technology

[0002] Heterojunction lightweight photovoltaic modules (HJT lightweight modules) are a new type of photovoltaic product that achieves "lightweighting" through material innovation and structural optimization based on heterojunction photovoltaic technology. It retains the core advantages of high efficiency and high stability of heterojunction cells, while significantly reducing weight by simplifying the structure and using flexible and lightweight materials, making it suitable for more special scenarios.

[0003] In existing technologies, n-type monocrystalline silicon wafers are used as the substrate (with better conductivity and stronger light absorption). Amorphous silicon thin films and doped oxide transparent conductive films are deposited on both sides in sequence to form a "symmetrical structure". Flexible films (such as EVA) may delaminate and delaminate under high temperature and high humidity environments. Especially when the module is frequently bent and thermally expanded and contracted, the stress concentration between the layers can easily lead to encapsulation failure. Now, a magnetic material layer (such as ferrite particles) is introduced to enhance the adhesion of the adhesive layer in the non-display area through magnetic adsorption and avoid delamination. However, the module is quickly fixed by clamps, which also depends on adhesives and special clips. If the adhesive has poor compatibility with the module surface, it will lead to fixation failure. Utility Model Content

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.

[0031] Reference Figure 1 , Figure 3 and Figure 4The present invention provides an embodiment of a heterojunction lightweight photovoltaic module structure, including a support frame 1, a plurality of fixed frames 2 are fixedly connected at equal intervals on the front side of the outer wall of the support frame 1, a photovoltaic panel 8 is installed on the inner wall of the fixed frame 2, and an installation mechanism 3 is installed on the outer wall of the fixed frame 2 and the photovoltaic panel 8. The installation mechanism 3 is used to facilitate the installation and disassembly of components, and a vibration damping mechanism 4 is installed on the inner wall of the fixed frame 2. The vibration damping mechanism 4 is used to reduce the impact of vibration on the structure. The mounting mechanism 3 includes a housing 302, which is mounted on the top wall of the fixing frame 2 and the photovoltaic panel 8. Multiple sliders 304 are equidistantly slidably connected to the lower part of the inner wall of the housing 302. A clamping plate 305 is fixedly connected to the bottom wall of the slider 304, and a fixing post 306 is threadedly connected to the inner wall of the clamping plate 305. A drive assembly 301 is mounted on the inner wall of the housing 302. The drive assembly 301 includes a threaded rod 3012, which is rotatably connected to the inner wall of the housing 302. A turntable 3011 is fixedly connected to the top of the threaded rod 3012. A locking block 303 is threadedly connected to the lower part of the outer wall of the threaded rod 3012. The locking block 303 is slidably connected to the inner wall of the housing 302 and to the inner wall of the slider 304.

[0032] Specifically, the photovoltaic panel 8 is placed in the fixing frame 2, and the outer shell 302 is placed on top of the fixing frame 2 and the photovoltaic panel 8. The turntable 3011 is rotated, which drives the threaded rod 3012 to rotate, thereby causing the clamping block 303 to move up and down. When the clamping block 303 moves upward, it pulls the slider 304 to move towards the middle of the outer shell 302, so that the clamping plate 305 clamps the outer wall of the fixing frame 2 and the photovoltaic panel 8. Finally, the fixing post 306 is screwed in to fix the structure between the clamping plates 305 together. The operation is convenient, a stable connection is formed, and it is convenient for installation and disassembly.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The vibration damping mechanism 4 includes a clamping block 401, which is rotatably connected to the inner wall of the fixed frame 2. A fixed rod 405 is fixedly connected to the bottom wall of the clamping block 401. A clamping piece 404 is rotatably connected to the lower middle part of the outer wall of the fixed rod 405. A clamping block 402 is fixedly connected to the upper middle part of the rear side of the outer wall of the fixed rod 405. An elastic component 403 is installed on the inner wall of the clamping block 402. The elastic component 403 includes a damping rod 4032, which is rotatably connected to the inner wall of the clamping block 402. A spring 4031 is installed on the outer wall of the damping rod 4032. The bottom end of the spring 4031 is rotatably connected to the inner wall of the clamping piece 404.

[0034] Specifically, the photovoltaic panel 8 sways within the fixed frame 2, thereby rotating the fixed rod 405. The fixed rod 405 drives the clamp 404, which in turn compresses the damping rod 4032. The damping rod 4032 compresses the spring 4031. When subjected to vibration, the damping rod 4032 and the spring 4031 undergo elastic deformation, absorbing and buffering vibration energy, preventing components from loosening, wearing, or even being damaged due to long-term vibration, and extending the service life of the equipment.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Antenna 5 is installed on the top of support frame 1. Antenna 5 is installed on the right side of the top wall of support frame 1. Junction box 6 is installed on the upper middle part of the rear side of the outer wall of support frame 1. Equipment box 7 is installed on the lower middle part of the rear side of the outer wall of support frame 1.

[0036] Specifically, antenna 5's main function is to receive and transmit signals. It can capture radio signals from the outside and transmit them to relevant equipment, while also transmitting signals generated by the equipment, ensuring smooth communication between the device and external systems and other devices. Junction box 6 is usually installed on the edge of the back of the component; it serves as the connection interface between the component and external circuits. The equipment enclosure 7 is mainly used to house and protect various electronic devices and components. It provides a relatively enclosed and safe environment for the internal equipment, resisting the effects of external dust, moisture, vibration, and temperature changes.

[0037] Working Principle: Carefully place the photovoltaic panel 8 into the corresponding position on the mounting frame 2. Then, remove the outer casing 302 and stably place it on top of the mounting frame 2 and the photovoltaic panel 8. Next, the operator needs to rotate the turntable 3011, which, through engagement with the threaded rod 3012, drives the threaded rod 3012 to rotate. As the threaded rod 3012 rotates, the locking block 303 moves up and down along the threads of the threaded rod 3012. When the locking block 303 moves upward, it pulls the slider 304 towards the center of the outer casing 302. The movement of the slider 304 allows the clamping plate 305 to tightly clamp the mounting frame 2 and the outer wall of the photovoltaic panel 8, ensuring they are securely fixed together. Finally, by screwing in the fixing post 306, the structure between the clamping plates 305 is further secured, forming a stable connection. This design is not only convenient to operate but also facilitates installation and disassembly, greatly improving work efficiency.

[0038] The photovoltaic panel 8 within the mounting frame 2 may sway due to external factors. This swaying causes the fixing rod 405 to rotate, which in turn drives the clamping plate 404. During this transmission, the clamping plate 404 compresses the damping rod 4032, which in turn compresses the spring 4031. The damping rod 4032 and spring 4031 undergo elastic deformation under vibration, effectively absorbing and buffering vibration energy. In this way, component loosening, wear, and even damage caused by long-term vibration can be avoided, thereby extending the equipment's service life. This design not only improves the stability and safety of the equipment but also ensures reliable operation in various environments.

[0039] 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.
