[0033] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Example 1

[0035] In related technologies, to ensure the mechanical strength of the frame structure and reduce damage to the photovoltaic panel during use, photovoltaic modules use a large amount of material, resulting in higher costs and greater weight. Common photovoltaic modules are prone to water accumulation or foreign object contamination, leading to hot spot effects, reducing the power generation efficiency and lifespan of the photovoltaic panel, and affecting the normal operation of the photovoltaic module.

[0036] To solve the above problems, refer to Figure 1 As shown, an embodiment of this application provides a border structure 100, which includes a border body 110, a first limiting member 120, and a second limiting member 130.

[0037] Specifically, in combination Figures 2 to 4 As shown, the first limiting member 120 is connected to the frame body 110. The first limiting member 120 is provided with a plurality of limiting parts 121, and a gap 122 is formed between adjacent limiting parts 121. Each limiting part 121 abuts against the photovoltaic panel 210. The second limiting member 130 is connected to the frame body 110, and the second limiting member 130 abuts against the side of the photovoltaic panel 210 opposite to the first limiting member 120. The second limiting member 130 is provided with a first liquid outlet 131. The frame body 110, the first limiting member 120, the second limiting member 130, and the photovoltaic panel 210 together define a first cavity 140. The first cavity 140 is connected to the first liquid outlet 131 and the gap 122. Accordingly, the frame body 110 is used to install and fix the photovoltaic panel 210. The limiting part 121 of the first limiting member 120 and the second limiting member 130 together limit and fix the photovoltaic panel 210. The gap 122 between adjacent limiting parts 121 facilitates the inflow of rainwater, which flows into the first cavity 140 through the gap 122. After cleaning, the rainwater flows out through the first liquid outlet 131, reducing the impact on the photovoltaic panel 210. In the event of water accumulation or obstruction by foreign objects, the frame structure 100 is cleaned. On the other hand, the multiple limiting parts 121 reduce the obstruction of the first limiting member 120 on one side of the frame structure 100 to the photovoltaic panel 210, increasing the exposed area of ​​the photovoltaic panel 210 and reducing the hot spot effect of the photovoltaic module 200, thereby improving the power generation conversion efficiency of the photovoltaic panel 210. The gap 122 also ensures smooth airflow in the frame structure 100, improving the heat dissipation effect of the frame structure 100. The first limiting member 120 of the multiple limiting parts 121 reduces the weight of the frame structure 100 while ensuring sufficient mechanical strength, thus achieving lightweighting of the frame structure 100.

[0038] It is understandable that the light spot effect is a phenomenon that occurs during the operation of the photovoltaic module 200. When part of the photovoltaic module 200 is shaded, the shaded part becomes a load, consuming the electricity generated by other parts, causing the temperature of this part to rise and forming a hot spot, thereby affecting the performance and lifespan of the entire photovoltaic module 200.

[0039] like Figure 2 As shown, the border structure 100 has a first direction. For example, the first direction is the thickness direction of the border structure 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the parts in the border structure 100 and should not be construed as limitations on this application.

[0040] In one embodiment, alternatively, referencing Figure 1 and Figure 3 As shown, multiple limiting parts 121 are arranged around the circumference of the photovoltaic panel 210. The multiple limiting parts 121 work together to limit the circumference of the photovoltaic panel 210 and fix the photovoltaic panel 210.

[0041] Optionally, combined Figure 4 and Figure 5 As shown, each of the limiting portions 121 extends toward one end of the photovoltaic panel 210 to form an extension section 1211, and the extension section 1211 of the limiting portion 121 is used to abut against and limit the photovoltaic panel 210.

[0042] In one embodiment, optionally, combining Figure 1 and Figure 2 As shown, the first limiting member 120 and the second limiting member 130 are arranged in parallel. Correspondingly, the first limiting member 120 and the second limiting member 130 are located on opposite sides of the photovoltaic panel 210, so as to limit and fix the photovoltaic panel 210 together by the first limiting member 120 and the second limiting member 130.

[0043] In one embodiment, alternatively, referencing Figure 1 As shown, the frame body 110 includes a first frame 111 and a second frame 112. The first frame 111 and the second frame 112 form a frame structure. The first frame 111 and the second frame 112 are connected end to end and surround the periphery of the photovoltaic panel 210. Of course, the first frame 111 and the second frame 112 can be provided with limiting parts 121 to limit and fix the photovoltaic panel 210.

[0044] In summary, the frame body 110 of the frame structure 100 is used to install and fix the photovoltaic panel 210. The limiting part 121 of the first limiting member 120 and the second limiting member 130 together limit and fix the photovoltaic panel 210. The gap 122 between adjacent limiting parts 121 facilitates the inflow of rainwater, etc. Rainwater flows into the first cavity 140 through the gap 122. After cleaning, the rainwater flows out through the first outlet 131, reducing the possibility of water accumulation or obstruction of foreign objects on the photovoltaic panel 210, thus cleaning the frame structure 100. On the other hand, the multiple limiting parts 121 make the frame structure The first limiting member 120 on one side of the frame structure 100 reduces the shading of the photovoltaic panel 210, increases the exposed area of ​​the photovoltaic panel 210, reduces the hot spot effect of the photovoltaic module 200, and thus improves the power generation conversion efficiency of the photovoltaic panel 210. The gap 122 can also ensure smooth airflow in the frame structure 100 and improve the heat dissipation effect of the frame structure 100. The first limiting member 120 of the multiple limiting parts 121 reduces the weight of the frame structure 100 while ensuring that the frame structure 100 has sufficient mechanical strength, thus achieving the lightweighting of the frame structure 100 and having better technical effects.

[0045] Example 2

[0046] refer to Figures 1 to 3 As shown, an embodiment of this application provides another border structure 100, which includes a border body 110, a first limiting member 120, and a second limiting member 130.

[0047] Specifically, in combination Figures 2 to 4 As shown, the first limiting member 120 is connected to the frame body 110. The first limiting member 120 is provided with multiple limiting parts 121, and a gap 122 is formed between adjacent limiting parts 121. Each limiting part 121 abuts against the photovoltaic panel 210. The second limiting member 130 is connected to the frame body 110, and the second limiting member 130 abuts against the side of the photovoltaic panel 210 away from the first limiting member 120. The second limiting member 130 is provided with a first liquid outlet 131. The frame body 110 is used to install and fix the photovoltaic panel 210. The limiting parts 121 of the first limiting member 120 and the second limiting member 130 together limit and fix the photovoltaic panel 210.

[0048] In this embodiment, the frame body 110, the first limiting member 120, the second limiting member 130, and the photovoltaic panel 210 together define a first cavity 140. The first cavity 140 is connected to the first liquid outlet 131 and the gap 122, respectively. Correspondingly, the gap 122 between adjacent limiting members 121 facilitates the inflow of rainwater, etc. Rainwater flows into the first cavity 140 through the gap 122, and after cleaning, it flows out through the first liquid outlet 131, reducing the possibility of water accumulation or obstruction of foreign objects on the photovoltaic panel 210, and achieving a cleaning effect on the frame structure 100. On the other hand, the multiple limiting parts 121 reduce the shading of the first limiting member 120 on one side of the frame structure 100, increase the exposed area of ​​the photovoltaic panel 210, reduce the hot spot effect of the photovoltaic module 200, and thus improve the power generation conversion efficiency of the photovoltaic panel 210. The gap 122 can also ensure smooth airflow in the frame structure 100 and improve the heat dissipation effect of the frame structure 100. The first limiting member 120 of the multiple limiting parts 121 reduces the weight of the frame structure 100 while ensuring that the frame structure 100 has sufficient mechanical strength, thus achieving the lightweighting of the frame structure 100.

[0049] Assembly process of frame structure 100: Silicone is placed inside frame structure 100 to facilitate the bonding and installation of photovoltaic panel 210 and frame structure 100. After standing for a preset time, the silicone is cured to make the connection between photovoltaic panel 210 and frame structure 100 stable. Junction box is connected to photovoltaic panel 210 to complete the installation of frame structure 100 and photovoltaic panel 210.

[0050] like Figure 2 As shown, the border structure 100 has a first direction. For example, the first direction is the thickness direction of the border structure 100.

[0051] In one embodiment, alternatively, referencing Figure 1 and Figure 3 As shown, a plurality of limiting portions 121 are arranged around the circumference of the photovoltaic panel 210. The plurality of limiting portions 121 work together to limit the circumference of the photovoltaic panel 210 and fix the photovoltaic panel 210. For example, the limiting portions 121 are located on the side of the first limiting member 120 near the photovoltaic panel 210, and the plurality of limiting portions 121 are arranged sequentially.

[0052] Optionally, combined Figure 4 and Figure 5As shown, each of the limiting parts 121 extends toward one end of the photovoltaic panel 210 to form an extension section 1211. The extension section 1211 of the limiting part 121 is used to abut against and limit the photovoltaic panel 210. Multiple limiting parts 121 are respectively arranged on the periphery of the photovoltaic panel 210 to reduce the possibility of shaking or falling off the circumferential position of the photovoltaic panel 210 and improve the installation stability of the photovoltaic module 200.

[0053] Optionally, such as Figure 4 As shown, the width of the extension segment 1211 from the frame body 110 to the photovoltaic panel 210 gradually decreases, so that the multiple limiting parts 121 form a sawtooth structure. In other words, the width of the extension segment 1211 of the sawtooth structure limiting part 121 towards the photovoltaic panel 210 gradually decreases, so that a gap 122 is formed between adjacent limiting parts 121. The gap 122 facilitates the inflow of rainwater and the connection of air passages. The gap 122 between adjacent limiting parts 121 can also increase the exposed area of ​​the photovoltaic panel 210, reduce the occurrence of light spot effect in the photovoltaic module 200, and improve the product performance of the photovoltaic module 200.

[0054] Optionally, the extension section 1211 has an arc-shaped structure. The arc-shaped extension section 1211 facilitates the limiting part 121 to abut against the photovoltaic panel 210, thereby limiting and fixing the photovoltaic panel 210, and forming a gap 122 at the limiting part 121. Further, the limiting part 121 includes a first protrusion 1212 and a second protrusion 1213. The first protrusion 1212 is connected to the second protrusion 1213 through the extension section 1211. The first protrusion 1212 abuts against the photovoltaic panel 210, and the second protrusion 1213 abuts against the photovoltaic panel 210. Accordingly, both the first protrusion 1212 and the second protrusion 1213 are used to abut against and limit the photovoltaic panel 210, and the extension section 1211 is located between the first protrusion 1212 and the second protrusion 1213. For example, the first protrusion 1212 and the second protrusion 1213 are arranged side by side with a gap, and the width of the second protrusion 1213 is greater than the width of the first protrusion 1212.

[0055] In one embodiment, optionally, combining Figure 1 and Figure 2 As shown, the first limiting member 120 and the second limiting member 130 are arranged in parallel. Correspondingly, the first limiting member 120 and the second limiting member 130 are located on opposite sides of the photovoltaic panel 210, so as to limit and fix the photovoltaic panel 210 together by the first limiting member 120 and the second limiting member 130.

[0056] Optionally, such as Figure 2 and Figure 5As shown, the frame body 110 and the second limiting member 130 define a second cavity 150. The second cavity 150 is connected to the first cavity 140 via the first liquid outlet 131. The second cavity 150 is provided with a second liquid outlet 151, which is opposite to the first liquid outlet 131. Accordingly, the second cavity 150 defined by the frame body 110 and the second limiting member 130 can reduce the weight of the frame structure 100 on the one hand, and allow rainwater to flow out through the second liquid outlet 151 of the second cavity 150 on the other hand, reducing the possibility of water accumulation in the second cavity 150, and achieving the purpose of cleaning the photovoltaic module 200. For example, the second cavity 150 is connected to the first cavity 140 via the first liquid outlet 131.

[0057] In one embodiment, alternatively, referencing Figure 1 As shown, the frame body 110 includes a first frame 111 and a second frame 112. The first frame 111 and the second frame 112 form a frame structure. The first frame 111 and the second frame 112 are connected end to end and surround the periphery of the photovoltaic panel 210. Of course, the first frame 111 and the second frame 112 can be provided with limiting parts 121 to limit and fix the photovoltaic panel 210. For example, the first frame 111 can be the long frame of the frame body 110, and the second frame 112 can be the short frame of the frame body 110. The first frame 111 and the second frame 112 are connected to form a rectangular structure.

[0060] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0061] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
