[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and feature vectors in the embodiments of this application can be arbitrarily combined with each other.

[0038] Photovoltaic modules include photovoltaic panels, photovoltaic frames surrounding the photovoltaic panels for support, and connecting brackets connecting the photovoltaic frames. However, existing connecting brackets are insufficient in structural strength, making them prone to deformation or even damage, which affects the service life and safety of photovoltaic modules.

[0039] To address the aforementioned issues, this application provides a connecting corner bracket for connecting a first photovoltaic frame and a second photovoltaic frame. The connecting corner bracket includes a first connecting arm, a second connecting arm, and a reinforcing structure. The first connecting arm is used for fixed connection with the first photovoltaic frame, and the second connecting arm is used for fixed connection with the second photovoltaic frame. The reinforcing structure is embedded inside the first connecting arm and / or the second connecting arm to enhance the structural strength of the connecting corner bracket, prevent deformation or damage during use, and thereby improve the service life and safety of the photovoltaic module.

[0040] An exemplary embodiment of this application provides a connection corner code 1, see [link]. Figures 1-10 The connecting corner code 1 is used to connect the first photovoltaic frame 21 and the second photovoltaic frame 22. The connecting corner code 1 includes a first connecting arm 111, a second connecting arm 121 and a reinforcing structure 13.

[0041] The first connecting arm 111 is fixedly connected to the first photovoltaic frame 21, and the second connecting arm 121 is fixedly connected to the second photovoltaic frame 22. For example, the first connecting arm 111 and the second connecting arm 121 are arranged perpendicularly to each other, and the first photovoltaic frame 21 and the second photovoltaic frame 22 are arranged perpendicularly to each other, so as to enclose a photovoltaic module with a frame structure, thereby improving the structural strength of the photovoltaic module.

[0042] See Figures 4-7 The reinforcing structure 13 is embedded inside the first connecting arm 111 and / or the second connecting arm 121 to enhance the structural strength of the connecting bracket 1, prevent it from deforming or being damaged during use, and thus improve the service life and safety of the photovoltaic module.

[0043] In some embodiments, the reinforcing structure 13 includes a first webbing 131, which is embedded inside the first connecting arm 111, with the extension direction of the first webbing 131 aligned with the extension direction of the first connecting arm 111. The webbing enhances the overall strength and toughness of the first connecting arm 111, making the connecting bracket 1 more durable. The alignment of the webbing's extension direction with that of the first connecting arm 111 ensures more even stress distribution on the connecting bracket 1, preventing damage caused by excessive localized stress. Furthermore, the weave structure of the webbing provides a degree of elasticity, allowing the connecting bracket 1 to adapt to certain deformations during installation and use, thereby improving the adaptability and ease of installation of the connecting bracket 1.

[0044] In some embodiments, the reinforcing structure 13 includes a second webbing 132 embedded inside the second connecting arm 121, with the extension direction of the second webbing 132 aligned with that of the second connecting arm 121. The second webbing 132 enhances the overall strength and toughness of the second connecting arm 121, ensuring sufficient connection strength for the connecting bracket 1 when connecting to the second photovoltaic frame 22. The alignment of the extension direction of the second webbing 132 with that of the second connecting arm 121 helps achieve uniform stress distribution under load, effectively preventing damage caused by localized stress concentration. Furthermore, the braided structure of the second webbing 132 gives the connecting bracket 1 a certain degree of elasticity. This elasticity allows the connecting bracket 1 to better adapt to deformation during installation and use, further enhancing its adaptability and installation flexibility.

[0045] In some embodiments, see Figures 1-7 The first connecting arm 111 has a first cylindrical structure, which can be exemplarily a hollow rectangular cylinder. The first cylindrical structure is formed by four first sidewalls 1111, and at least one first sidewall 1111 is provided with a first webbing 131. The extension direction of the first webbing 131 is consistent with the extension direction of the first sidewall 1111, which not only enhances the structural strength of the first connecting arm 111 but also helps to disperse the stress on the connecting bracket 1 under load, effectively avoiding damage caused by stress concentration. The braided structure of the first webbing 131 gives the connecting bracket 1 a certain degree of elasticity, enabling it to maintain good adaptability to changes in the external environment and minor deformations during installation, thereby extending the service life of the connecting bracket 1.

[0046] In some embodiments, see Figures 1-7 The second connecting arm 121 has a second cylindrical structure, which can be exemplarily a hollow rectangular cylinder. The second cylindrical structure is formed by four second sidewalls 1211, and at least one second sidewall 1211 is provided with a second webbing 132. The extension direction of the second webbing 132 is consistent with the extension direction of the second sidewall 1211, which not only enhances the structural strength of the second connecting arm 121 but also helps to disperse the stress on the connecting bracket 1 under load, effectively avoiding damage caused by stress concentration. The braided structure of the second webbing 132 gives the connecting bracket 1 a certain degree of elasticity, enabling it to maintain good adaptability to changes in the external environment and minor deformations during installation, thereby extending the service life of the connecting bracket 1.

[0047] In some embodiments, see Figures 4-5 In the cross-section of the first cylindrical structure, the extension direction of the first webbing 131 is set at an angle to the extension direction of the first sidewall 1111, so that when the first sidewall 1111 is subjected to external forces in different directions, the first webbing 131 can more effectively disperse and resist the impact of the external forces, thereby improving the shear resistance and overall stability of the connecting corner bracket 1.

[0048] In some embodiments, see Figures 6-7 In the cross-section of the second cylindrical structure, the extension direction of the second webbing 132 is set at an angle to the extension direction of the second sidewall 1211, so that when the second sidewall 1211 is subjected to external forces in different directions, the second webbing 132 can more effectively disperse and resist the impact of the external forces, thereby improving the shear resistance and overall stability of the connecting corner bracket 1.

[0049] In some embodiments, refer to Figures 4-5Multiple first webbing strips 131 are provided on the same first sidewall 1111. In the cross-section of the first cylindrical structure, the multiple first webbing strips 131 on the same first sidewall 1111 extend in different directions. This design can enhance the structural strength of the first sidewall 1111, thereby further enhancing the structural strength and stability of the connecting angle bracket 1 in multiple directions. Specifically, the first webbing strips 131 with different extension directions can more effectively resist pressure from different directions, improving the overall rigidity and durability of the connecting angle bracket 1. In addition, this design also helps to optimize the weight distribution of the first connecting arm 111, making it more balanced when bearing load and reducing the risk of damage caused by stress concentration.

[0050] In some embodiments, refer to Figures 6-7 Multiple second webbing strips 132 are provided on the same second sidewall 1211. In the cross-section of the second cylindrical structure, the extension directions of the multiple second webbing strips 132 on the same second sidewall 1211 are different. This design can enhance the structural strength of the second sidewall 1211, thereby further enhancing the structural strength and stability of the connecting bracket 1 in multiple directions. Specifically, the second webbing strips 132 with different extension directions can more effectively resist pressure from different directions, improving the overall rigidity and durability of the connecting bracket 1. In addition, this design also helps to optimize the weight distribution of the second connecting arm 121, making it more balanced when bearing load and reducing the risk of damage caused by stress concentration.

[0051] In some embodiments, refer to Figures 4-7 The reinforcing structure 13 includes felt 133, which can effectively enhance the overall structural strength of the connecting corner bracket 1, making the connecting corner bracket 1 less prone to damage during long-term use.

[0052] In some embodiments, refer to Figure 8 The first webbing 131 is woven from multiple strands of wire, and the extension direction of each strand is set at an angle to the extension direction of the first connecting arm 111. This allows the first connecting arm 111 to have high structural strength in different directions, thereby effectively improving the overall deformation resistance of the connecting corner bracket 1.

[0053] In some embodiments, refer to Figure 9 The second webbing 132 is woven from multiple strands of wire, and the extension direction of each strand is set at an angle to the extension direction of the second connecting arm 121. This allows the second connecting arm 121 to have high structural strength in different directions, thereby effectively improving the overall deformation resistance of the connecting corner bracket 1.

[0054] In some embodiments, refer to Figures 8-9The multiple wire bundles in the first webbing 131 and the second webbing 132 are all fiber bundles 134. The first webbing 131 and the second webbing 132, which are composed of fiber bundles 134, have the characteristics of high strength and high modulus, which can significantly improve the load-bearing capacity and deformation resistance while maintaining the overall lightweight structure of the photovoltaic frame.

[0055] In some embodiments, refer to Figures 1-10 The connecting bracket 1 includes a detachable first connecting structure 11 and a second connecting structure 12. A first connecting arm 111 is disposed on the first connecting structure 11, and a second connecting arm 121 is disposed on the second connecting structure 12. The first connecting structure 11 is fixedly connected to the first photovoltaic frame 21, and the second connecting structure 12 is fixedly connected to the second photovoltaic frame 22. Setting the first connecting structure 11 and the second connecting structure 12 to be detachable facilitates the assembly between the first connecting structure 11 and the first photovoltaic frame 21, as well as the assembly between the second connecting structure 12 and the second photovoltaic frame 22. At the same time, this detachable connection method also makes the connecting bracket 1 more convenient to repair or replace, reducing maintenance costs.

[0056] In some embodiments, refer to Figures 1-10 The first connecting structure 11 also includes a snap-fit ​​part 112, which is L-shaped with the first connecting arm 111 and snaps into the second connecting arm 121. After the second connecting arm 121 is connected to the snap-fit ​​part 112, the second connecting arm 121 is perpendicular to the first connecting arm 111. The first photovoltaic frame 21 and the second photovoltaic frame 22 are perpendicular to each other. The first connecting structure 11 is fixedly connected to the first photovoltaic frame 21, and the second connecting structure 12 is fixedly connected to the second photovoltaic frame 22, so as to form a frame-type photovoltaic module, thereby improving the structural strength of the photovoltaic module.

[0057] In some embodiments, the snap-fit ​​portion 112 includes an elastic arm 1121 and a snap-fit ​​protrusion 1122 disposed at the free end of the elastic arm 1121. The snap-fit ​​protrusion 1122 snaps into the second connecting arm 121, and the second connecting arm 121 is sleeved on the outside of the snap-fit ​​protrusion 1122. The elastic arm 1121 has a certain elastic deformation capability, so that the snap-fit ​​protrusion 1122 can generate a certain displacement when subjected to external force, thereby facilitating the snap-fit ​​and disassembly of the second connecting arm 121. A mutually cooperating snap-fit ​​structure is provided between the snap-fit ​​protrusion 1122 and the second connecting arm 121. For example, the second connecting arm 121 is provided with a slot 122 adapted to the snap-fit ​​protrusion 1122. When the snap-fit ​​portion 112 snaps into the second connecting arm 121, the snap-fit ​​protrusion 1122 can hook the slot 122, thereby achieving a stable connection between the snap-fit ​​portion 112 and the second connecting arm 121. This snap-fit ​​method is not only simple in structure but also provides a strong connection, which can effectively prevent accidental separation between the first connection structure 11 and the second connection structure 12, thereby improving the overall stability of the photovoltaic module.

[0058] The reinforcing structure 13 is also embedded inside the elastic arm 1121 to enhance the structural strength of the elastic arm 1121 and prevent the elastic arm 1121 from deforming or breaking when used for a long time or subjected to a large external force. By setting the reinforcing structure 13, the reliability and durability of the connecting bracket 1 are further improved.

Figure 10 The photovoltaic module includes a first photovoltaic frame 21, a second photovoltaic frame 22 and a connecting corner bracket 1. The connecting corner bracket 1 is the connecting corner bracket 1 as described above, and adjacent first photovoltaic frames 21 and second photovoltaic frames 22 are fixedly connected by the connecting corner bracket 1.

[0060] The photovoltaic module includes two first photovoltaic frames 21, two second photovoltaic frames 22, and four connecting corner brackets 1. Adjacent first photovoltaic frames 21 and second photovoltaic frames 22 are fixedly connected by a connecting corner bracket 1. The two first photovoltaic frames 21 and two second photovoltaic frames 22 are enclosed by the four connecting corner brackets 1 to form a rectangular ring frame set at the edge of the photovoltaic panel. The four connecting corner brackets 1 are respectively set at the four corners of the rectangular ring frame.

[0061] The connecting corner bracket 1 of this application is used to connect the first photovoltaic frame 21 and the second photovoltaic frame 22. The connecting corner bracket 1 includes: a first connecting arm 111, a second connecting arm 121 and a reinforcing structure 13. The first connecting arm 111 is used to be fixedly connected to the first photovoltaic frame 21, and the second connecting arm 121 is used to be fixedly connected to the second photovoltaic frame 22. The reinforcing structure 13 is embedded in the inside of the first connecting arm 111 and / or the inside of the second connecting arm 121 to enhance the structural strength of the connecting corner bracket 1, prevent it from deforming or being damaged during use, and thus improve the service life and safety of the photovoltaic module.
