Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic module technical field, specifically provide a frame structure and photovoltaic module of photovoltaic module. BACKGROUND

[0002] In photovoltaic panels, the frame serves to protect and support the photovoltaic panels, while the corner code is mainly used to connect and fix the corners of the photovoltaic panel frame, and serves to increase the overall stability, structural strength, connection strength and load capacity of the frame. In some special scenarios, such as strong winds, sandstorms and other severe weather conditions, the use of corner codes can effectively prevent the deformation or damage of the photovoltaic panel frame, thereby ensuring the normal operation of the entire photovoltaic system. Secondly, the structural characteristics of the photovoltaic panel frame also affect the demand for corner codes. Some photovoltaic panel frames use special materials or designs and have high structural strength and stability, in which case additional corner codes may not be needed. In addition, some photovoltaic panel frames are designed to incorporate corner codes into the frame, which can ensure the stability of the frame and simplify the installation process.

[0003] In practical applications, we need to determine whether to use corner codes based on specific scenarios and needs. For example, in some areas with strong winds and sand, it is necessary to use corner codes to ensure the stability and safety of the photovoltaic panel frame. In some relatively mild climate conditions, if the photovoltaic panel frame itself has high stability and aesthetics, additional corner codes may not be needed.

[0004] In summary, whether or not a photovoltaic panel frame needs corner codes depends on the specific application scenario and the frame structure. When choosing whether to use corner codes, we need to consider various factors, including environmental conditions, frame materials, design styles, etc. Only in this way can we ensure the stability and safety of the photovoltaic panel frame, thereby ensuring the normal operation of the entire photovoltaic system.

[0005] In existing photovoltaic modules and their frame structures, the corner codes are not securely connected to the frame. Moreover, when the photovoltaic module is in use, dust or water accumulated on the photovoltaic panel falls into the frame structure, which is not convenient to clean. Long-term accumulation can adversely affect the performance of the photovoltaic module. INVENTION CONTENTS

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] With the rapid development of the photovoltaic industry, the quality and reliability of photovoltaic modules are constantly improving. As a key component of the frame connection, the performance and installation process of the corner code have attracted more and more attention. In the existing photovoltaic module and frame structure, the corner code is not connected stably with the frame. Moreover, when the photovoltaic module is in use, the dust or water accumulated on the photovoltaic panel falls into the frame structure, which is not convenient to clean. Long-term accumulation will adversely affect the performance of the photovoltaic module.

[0033] As shown in Figure 1 The frame structure of the photovoltaic module provided by the present application comprises a corner code 1 and a frame body 2 connected by the corner code 1. Two frame bodies 2 can be connected by one corner code 1. Usually, four frame bodies 2 are connected by four corner codes 1 to form a closed quadrilateral frame structure as the frame of the photovoltaic module.

[0034] As shown in Figures 2 to 5As shown, the corner code 1 includes a corner code body 11 and connecting arms 12 arranged at both ends of the corner code body 11. The frame body 2 is provided with a limiting cavity 21, and the corner code body 11 is connected with the frame body 2 by the connecting arms 12 cooperating with the limiting cavity 21. The corner code body 11 can be arranged in a quarter circular arc shape, and the connecting arms 12 are arranged on the end faces of both ends of the corner code body 11, respectively. Arranging the corner code body 11 in a round corner shape not only improves the aesthetics, but also improves the safety. The sharp corners can be eliminated, which brings potential safety hazards to operators and users during the manufacturing and use of the photovoltaic module. When the corner code 1 is connected with the frame body 2, the connecting arms 12 arranged on the end faces of the corner code body 11 are inserted into the limiting cavities 21 of the frame body 2, so that the corner code 1 is connected with the frame body 2.

[0035] Further, as shown in Figure 2 and Figure 3 , two connecting arms 12 are arranged symmetrically at both ends of the corner code body 11; the connecting arms 12 are provided with clamping portions 121 at the ends connected with the limiting cavities 21 in the frame body 2. Figure 4 and Figure 5 , two reinforcing portions 23 are arranged oppositely in the limiting cavity 21, and the clamping holes 24 are arranged on the reinforcing portions 23; when the connecting arms 12 cooperate with the limiting cavities 21, the clamping holes 24 are clamped and cooperated with the corresponding clamping portions 121.

[0036] Further, as shown in Figure 7 , the connecting arms 12 are elastic, and the distance between the clamping portions 121 of the two connecting arms 12 arranged symmetrically on the end faces of the connecting arms 12 is greater than the distance between the two reinforcing portions 23 arranged in the limiting cavity 21; when the two connecting arms 12 are inserted into the limiting cavities 21 of the frame body 2, the clamping portions 121 of the connecting arms 12 are compressed by the reinforcing portions 23 arranged in the limiting cavities 21 of the frame body 2, so that the two connecting arms 12 move closer to each other. When the connecting arms 12 continue to move into the limiting cavities 21, the clamping portions 121 at the ends of the connecting arms 12 enter the clamping holes 24 on the reinforcing portions 23, the two connecting arms 12 rebound to the initial state, so that the clamping portions 121 at the ends of the connecting arms 12 are clamped with the clamping holes 24 on the reinforcing portions 23. At this time, the frame body 2 is fixedly connected with the corner code 1.

[0037] In addition, the reinforcing portions 23 arranged in the limiting cavities 21 increase the supporting surface, thereby improving the load strength of the frame body 2, so that the frame of the photovoltaic module formed by connecting the corner code 1 with the frame body 2 can be applied to higher load requirement application scenarios.

[0038] In order to make the connection of the corner code 1 and the frame body 2 more stable, as shown in Figure 2 and Figure 3As shown, a limiting boss 14 is arranged between the two connecting arms 12 symmetrically arranged at the end of the corner code 1, and a limiting groove 15 is arranged on the side wall of the limiting boss 14. Correspondingly, as shown Figure 5 As shown, a positioning protrusion 22 is arranged on the side wall opposite to the side wall of the limiting boss 14 of the limiting cavity 21, for cooperating with the limiting groove 15 arranged on the side wall of the limiting boss 14. With the insertion of the connecting arm 12 at the end of the corner code 1 into the limiting cavity 21 of the frame body 2, the limiting boss 14 is also inserted into the limiting cavity 21. At the same time, the limiting groove 15 arranged on the side wall of the limiting boss 14 cooperates with the positioning protrusion 22 arranged on the side wall opposite to the side wall of the limiting boss 14 of the limiting cavity 21. Through the above arrangement, the corner code 1 and the frame body 2 can be more stably connected together through the clamping of the clamping part 121 and the clamping hole 24 and the cooperation of the limiting groove 15 and the positioning protrusion 22. The clamping of the clamping part 121 and the clamping hole 24 increases the pull-out force of the corner code 1 and the frame body 2, overcoming the insufficient pull-out force of the existing frame structure of the photovoltaic module.

[0039] In addition, the end faces of the corner code 1 and the frame body 2 are right angles, without the need for beveling the frame (for example, 45° beveling), simplifying the processing process. Moreover, the connection of the corner code 1 and the frame body 2 through the clamping of the clamping part 121 and the clamping hole 24 also does not require the addition of riveting points. Both the influence of the depth and position of the riveting points arranged on the frame in the existing frame structure on the pull-out force of the frame structure and the assembly efficiency of the frame structure are improved.

[0040] As shown Figure 2 and Figure 3 A first hollow groove 13 is arranged on the bottom surface of the corner code body 11. A first mounting groove 16 is arranged in the corner code body 11, and the first hollow groove 13 is arranged in the area of the bottom surface of the corner code body 11 opposite to the first mounting groove 16, so that the first mounting groove 16 is communicated with the outside through the first hollow groove 13. As shown Figure 1 、 Figure 4 and Figure 5 A second mounting groove 25 is arranged in the frame body 2, and a second hollow groove 26 is arranged on the bottom surface of the frame body 2, which is arranged in the area of the bottom surface of the frame body 2 opposite to the second mounting groove 25, so that the second mounting groove 25 is communicated with the outside through the second hollow groove 26.

[0041] When the corner code 1 is connected with the frame body 2, the first installation slot 16 arranged in the corner code 1 is connected with the second installation slot 25 arranged in the frame body 2 to form a through slot for accommodating components of the photovoltaic module. The first hollow slot 13 arranged on the bottom surface of the corner code body 11 is aligned with the second hollow slot 26 arranged on the bottom surface of the frame body 2 to form a continuous hollow slot, so that the hollow slot is communicated with the through slot, thereby enabling the dust and water accumulated in the first installation slot 16 and the second installation slot 25 by the surface of the photovoltaic module to be automatically discharged through the first hollow slot 13 and the second hollow slot 26. The dust and water accumulated in the first installation slot 16 and the second installation slot 25 cannot be discharged in time, which affects the performance and normal operation of the photovoltaic module.

[0042] Further, as shown in Figure 4 and Figure 5 , a drain hole 27 is arranged in the frame body 2, for example, on the side wall of the frame body 2 away from the second installation slot 25. The accumulated water in the limiting cavity 21 in the frame body 2 can be discharged through the drain hole 27.

[0043] As shown in Figure 6 and Figure 7 , the application further provides a photovoltaic module comprising the frame structure of the photovoltaic module as described above and a photovoltaic laminate 3 fixed in the frame structure of the photovoltaic module. The edge of the photovoltaic laminate 3 is arranged in the through slot formed by the first installation slot 16 in the corner code 1 and the second installation slot 25 in the frame body 2.

[0044] So far, the technical scheme of the application has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to related technical features without departing from the principles of the application, and the technical scheme after the changes or replacements will fall within the protection scope of the application.
