[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.

[0037] In order to improve the aesthetics of the connection of the photovoltaic frame, in the related art, an L-shaped connection angle bracket is used to fix and connect two mutually perpendicular photovoltaic frames. However, the photovoltaic modules connected by such connection angle brackets have the problem of poor sealing performance, which is difficult to meet the sealing requirements of the photovoltaic modules.

[0038] Based on this, the present application provides a connection angle code, which is used to connect a first photovoltaic frame and a second photovoltaic frame. The first photovoltaic frame and the second photovoltaic frame are vertically arranged. The first connection sleeve of the connection angle code is plugged into the port of the first photovoltaic frame. The clamping part extends along the extension direction of the second photovoltaic frame. The second connection sleeve is plugged into the second photovoltaic frame. The clamping part is inserted into the second connection sleeve through the first port of the second connection sleeve and is clamped and fixed with the second connection sleeve to achieve the connection between the first photovoltaic frame and the second photovoltaic frame. Since the second port of the first connection sleeve is provided with a first sealing cover, and the second port of the second connection sleeve is also provided with a second sealing cover, the connection angle code can be sealed. When the connection angle code is used to connect the frame of the photovoltaic module, the sealing of the photovoltaic module can be improved.

[0039] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.

[0040] like Figure 1 As shown, an exemplary embodiment of the present application provides a connection angle code for connecting a first photovoltaic frame 20 and a second photovoltaic frame 30, wherein the first photovoltaic frame 20 and the second photovoltaic frame 30 are arranged vertically, and the connection angle code 10 includes a first connection sleeve 1 and a clamping portion 2, the first connection sleeve 1 is used to be plugged with the port of the first photovoltaic frame 20, the clamping portion 2 extends along the extension direction of the second photovoltaic frame 30, the first port 11 of the first connection sleeve is connected to the clamping portion 2, and the second port 12 of the first connection sleeve is provided with a first sealing cover 3. The connection angle code 10 also includes a second connection sleeve 4, the second connection sleeve 4 is used to be plugged with the second photovoltaic frame 30, the clamping portion 2 is inserted into the second connection sleeve 4 through the first port 41 of the second connection sleeve and is clamped and fixed with the second connection sleeve 4, and the second port 42 of the second connection sleeve is provided with a second sealing cover 5.

[0041] This embodiment does not limit the specific material and fixing method of the photovoltaic frame and the connecting angle code 10. For example, the photovoltaic frame can be a glass fiber resin composite material, and the connecting angle code 10 can be made of plastic material, and the photovoltaic frame and the connecting angle code 10 can be fixed by, for example, bonding. Of course, it is understandable that the photovoltaic frame and the connecting angle code 10 can also be made of metal material, and the two can be fixed by welding, clamping, etc.

[0042] In order to facilitate the description of the assembly process of the connecting angle code 10, the photovoltaic frame and the connecting angle code 10 in this embodiment are fixed by glue. In order to connect the first photovoltaic frame 20 and the second photovoltaic frame 30 which are perpendicular to each other, during assembly, glue is applied to the ports of the first photovoltaic frame 20 and the second photovoltaic frame 30 respectively, and then the first connecting sleeve 1 is inserted into the port of the first photovoltaic frame 20, and the second connecting sleeve 4 is inserted into the port of the second photovoltaic frame 30. After the glue solidifies, the connection between the first connecting sleeve 1 and the first photovoltaic frame 20 and the connection between the second connecting sleeve 4 and the second photovoltaic frame 30 are completed. At this time, the clamping part 2 is inserted into the second connecting sleeve 4 through the first port 41 of the second connecting sleeve and is clamped and fixed with the second connecting sleeve 4 to realize the connection between the first photovoltaic frame 20 and the second photovoltaic frame 30. In this embodiment, by providing a first sealing cover 3 at the first connecting sleeve 1 and a second sealing cover 5 at the second connecting sleeve 4, the sealing of the photovoltaic assembly after connection can be improved. At the same time, due to the setting of the second sealing cover 5, when the second connecting sleeve 4 is inserted into the port of the second photovoltaic frame 30, the glue at the port of the second photovoltaic frame 30 can be prevented from entering the cavity of the second connecting sleeve 4 through the second port 42 of the second connecting sleeve, thereby ensuring that the clamping part 2 and the second connecting sleeve 4 can be smoothly clamped.

[0043] In an exemplary embodiment, the first sealing cover 3 includes a first outer cover body 31 and a first insertion portion 32 disposed on the inner surface of the first outer cover body 31, the first insertion portion 32 is inserted into the first connecting sleeve 1 through the second port 12 of the first connecting sleeve, and abuts against the inner wall of the first connecting sleeve 1. The second sealing cover 5 includes a second outer cover body 51 and a second insertion portion 52 disposed on the inner surface of the second outer cover body 51, the second insertion portion 52 is inserted into the second connecting sleeve 4 through the second port 42 of the second connecting sleeve, and abuts against the inner wall of the second connecting sleeve 4.

[0044] In this embodiment, the first insertion portion 32 is inserted through the second port 12 of the first connecting sleeve to seal the first connecting sleeve 1 ; the second insertion portion 52 is inserted through the second port 42 of the second connecting sleeve to seal the second connecting sleeve 4 .

[0045] In order to prevent the first sealing cover 3 and the second sealing cover 5 from being offset, the size of the first sealing cover 3 is larger than the inner diameter of the first connecting sleeve 1, and the size of the second sealing cover 5 is larger than the inner diameter of the second connecting sleeve 4. In order to make it easier for the first connecting sleeve 1 to be inserted into the first photovoltaic frame 20, the outer diameter of the first sealing cover 3 is slightly smaller than the outer diameter of the first connecting sleeve 1; similarly, the outer diameter of the second sealing cover 5 is slightly smaller than the outer diameter of the second connecting sleeve 4.

[0046] In order to improve the stability of the connection between the first sealing cover 3 and the first connecting sleeve 1, and to improve the stability of the connection between the second sealing cover 5 and the second connecting sleeve 4, ultrasonic welding (ultrasonic welding) can be used to melt the joint surface of the first sealing cover 3 and the first connecting sleeve 1, and to melt the joint surface of the second sealing cover 5 and the second connecting sleeve 4. Taking the first sealing cover 3 and the first connecting sleeve 1 as an example, the joint surface of the first sealing cover 3 and the first connecting sleeve 1 refers to a surface or multiple surfaces between the first sealing cover 3 and the first connecting sleeve 1 that are in contact with each other and welded. When ultrasonic welding is performed, the joint surface of the first sealing cover 3 is welded to the joint surface of the first connecting sleeve 1.

[0047] In an exemplary embodiment, referring to Figure 2 The first inserting portion 32 includes a first connecting portion 321 and a first welding portion 322. The first connecting portion 321 is fixedly connected to the first outer cover 31, and the first welding portion 322 is connected to one end of the first connecting portion 321 away from the first outer cover 31. The second end 12 of the first connecting sleeve is provided with a first connecting groove 15 adapted to the first connecting portion 321. The first connecting portion 321 abuts against the side wall of the first connecting groove 15, and the first welding portion 322 is used to weld with the bottom of the first connecting groove 15. The second inserting portion 52 includes a second connecting portion 521 and a second welding portion 522. The second connecting portion 521 is fixedly connected to the second outer cover 51, and the second welding portion 522 is connected to one end of the second connecting portion 521 away from the second outer cover 51. The second end 42 of the second connecting sleeve is provided with a second connecting groove 45 adapted to the second connecting portion 521. The second connecting portion 521 abuts against the side wall of the second connecting groove 45, and the second welding portion 522 is used to weld with the bottom of the second connecting groove 45.

[0048] The selection of the joint surface has a certain influence on the welding quality and the bonding strength between the connection angle code 10 and the photovoltaic frame. In this embodiment, by welding the first welding portion 322 to the bottom of the first connection groove 15 and by welding the second welding portion 522 to the bottom of the second connection groove 45, it is possible to avoid the influence of the exposed welding point on the appearance of the connection angle code 10, the bonding strength between the connection angle code 10 and the photovoltaic frame, and the sealing when gluing the connection angle code 10 and the photovoltaic frame.

[0049] Before the first sealing cover 3 is assembled with the first connecting sleeve 1, one end of the first welding part 322 close to the first connecting groove 15 is a sharp angle structure; before the second sealing cover 5 is assembled with the second connecting sleeve 4, one end of the second welding part 522 close to the second connecting groove 45 is a sharp angle structure. When the first sealing cover 3 is assembled with the first connecting sleeve 1 by ultrasonic welding, the side wall of the first connecting part 321 abuts against the side wall of the first connecting groove 15, and the first welding part 322 melts, thereby welding the first connecting part 321 to the bottom of the first connecting groove 15, so that the first sealing cover 3 is fixedly connected with the first connecting sleeve 1. Similarly, when the second sealing cover 5 is assembled with the second connecting sleeve 4 by ultrasonic welding, the side wall of the second connecting part 521 abuts against the side wall of the second connecting groove 45, and the second welding part 522 melts, thereby welding the second connecting part 521 to the bottom of the second connecting groove 45, so that the second sealing cover 5 is fixedly connected with the second connecting sleeve 4.

[0050] In order to make the first insertion part 32 more easily inserted into the first connecting sleeve 1, the outer diameter of the first connecting part 321 is slightly smaller than the inner diameter of the first connecting groove 15; similarly, in order to make the second insertion part 52 more easily inserted into the second connecting sleeve 4, the outer diameter of the second connecting part 521 is slightly smaller than the inner diameter of the second connecting groove 45.

[0051] In an exemplary embodiment, referring to Figure 1 and Figure 3 The first connecting sleeve 1 includes a first pipe section 13 and a second pipe section 14. One end of the first pipe section 13 is connected to the clamping portion 2, and the other end of the second pipe section 14 is connected to one end of the second pipe section 14. A first sealing cover 3 is provided at the other end of the second pipe section 14. The outer surface of the first pipe section 13 is provided with a plurality of first recessed structures 131. The outer surface of the second pipe section 14 is a smooth surface. The cross-sectional area of ​​the second pipe section 14 gradually decreases in the direction away from the first pipe section 13. The first pipe section 13 has a first length L1, and the second pipe section 14 has a second length L2. The first length L1 is (0.8 to 1.5) times the second length L2. The second connecting sleeve 4 includes a third pipe section 43 and a fourth pipe section 44. One end of the third pipe section 43 constitutes a first port 41 of the second connecting sleeve. The other end of the third pipe section 43 is connected to one end of the fourth pipe section 44. A second sealing cover 5 is provided at the other end of the fourth pipe section 44. The outer surface of the third pipe segment 43 is provided with a plurality of second recessed structures 431, and the outer surface of the fourth pipe segment 44 is a smooth surface, and the cross-sectional area of ​​the fourth pipe segment 44 gradually decreases in a direction away from the third pipe segment 43. The third pipe segment 43 has a third length L3, and the fourth pipe segment 44 has a fourth length L4, and the third length L3 is (0.8 to 1.5) times the fourth length L4.

[0052] In this embodiment, the cross-sectional area of ​​the second pipe section 14 gradually decreases in a direction away from the first pipe section 13 , so that the first connecting sleeve 1 can be inserted into the first photovoltaic frame 20 more easily.

[0053] The outer surface of the first pipe section 13 is provided with a plurality of first recessed structures 131, which is conducive to improving the bonding strength between the first connecting sleeve 1 and the first photovoltaic frame 20. For example, when the first photovoltaic frame 20 and the first connecting sleeve 1 are bonded and fixed by glue, the outer surface of the first pipe section 13 is provided with a plurality of first recessed structures 131, which can increase the coverage area of ​​the glue, thereby improving the bonding strength between the first connecting sleeve 1 and the first photovoltaic frame 20.

[0054] Although the outer surface of the first pipe section 13 is provided with a plurality of first recessed structures 131, the bonding strength between the first connecting sleeve 1 and the first photovoltaic frame 20 can be improved, but when the length of the first pipe section 13 is too long, the sealing of the photovoltaic module will be reduced and the problem of glue overflow will occur. Therefore, in this embodiment, by limiting the length of the first pipe section 13 and the second pipe section 14, the first length L1 is (0.8 to 1.5) times the second length L2. In this way, when the first connecting sleeve 1 is bonded to the first photovoltaic frame 20 with glue, the glue can be applied to the outer surface of the second pipe section 14. When the first connecting sleeve 1 is inserted into the first photovoltaic frame 20, the overflow of glue can be avoided and the sealing of the photovoltaic module can be improved. Exemplarily, the first length L1 is 0.8 times, 1 times, 1.2 times or 1.5 times the second length L2.

[0055] Similarly, the structure and function of the third pipe segment 43, the fourth pipe segment 44 and the second recessed structure 431 on the outer surface of the third pipe segment 43 in the second connecting sleeve 4 are the same as the structure and function of the first pipe segment 13, the second pipe segment 14 and the first recessed structure 131 in the first connecting sleeve 1, and will not be repeated here.

[0056] In an exemplary embodiment, the first recessed structure 131 extends axially along the first tube segment 13, and a plurality of first recessed structures 131 are arranged at intervals along the circumference of the first tube segment 13. The second recessed structure 431 extends axially along the third tube segment 43, and a plurality of second recessed structures 431 are arranged at intervals along the circumference of the third tube segment 43.

[0057] In this embodiment, the provision of the first recessed structure 131 and the second recessed structure 431 can improve the bonding strength between the connecting corner code 10 and the photovoltaic frame.

[0058] In an exemplary embodiment, referring to Figure 1 , Figure 4 and Figure 5The clamping portion 2 includes a support member 21, one end of the support member 21 is connected to the first connecting sleeve 1, and the other end of the support member 21 is provided with two opposite elastic arms 22, the fixed end of the elastic arm 22 is connected to the support member 21, and the free end of the elastic arm 22 is provided with a clamping protrusion 23, the protruding directions of the clamping protrusions 23 on the two elastic arms 22 are opposite, and the outer surface of the support member 21 is smoothly transitioned and connected with the outer surface of each elastic arm 22.

[0059] In this embodiment, when the clamping portion 2 is inserted into the second connecting sleeve 4, under the action of the second connecting sleeve 4, the two elastic arms 22 can move towards each other. When the elastic arms 22 move to the second end of the second connecting sleeve 4, the two elastic arms 22 are reset and opened after losing the external force, and the clamping protrusion 23 at the free end of the elastic arm 22 is clamped with the second connecting sleeve 4. For example, referring to Figure 6 A snap-fit ​​groove 441 is provided at the second port 41 of the second connecting sleeve. The snap-fit ​​groove 441 and the inner wall of the second connecting sleeve 4 form a stepped groove. The stepped groove cooperates with the snap-fit ​​protrusion 23 to realize the snap-fit ​​fixation of the second connecting sleeve 4 and the snap-fit ​​part 2.

[0060] Among them, the outer surface of the support member 21 is smoothly transitionally connected with the outer surface of each elastic support arm 22, which can avoid collision between the two when the elastic support arm 22 is inserted into the second connecting sleeve 4, ensure the smoothness of the plug-in, and avoid damage to the connecting angle code 10 during plug-in.

[0061] In order to improve the stability and strength of the two elastic arms 22 , in an exemplary embodiment, a reinforcing plate 24 is connected between the two elastic arms 22 , and the reinforcing plate 24 extends from the fixed end of the elastic arm 22 to the middle area of ​​the elastic arm 22 .

[0062] In an exemplary embodiment, referring to Figure 6 and Figure 7 The elastic arm 22 is provided with a first groove 221 and / or a second groove 222; along the depth direction of the first groove 221, the cross-sectional area of ​​the first groove 221 is the same; along the depth direction of the second groove 222, the cross-sectional area of ​​the second groove 222 gradually decreases.

[0063] The present embodiment has no limitation on the material of the elastic arm 22, which can be metal or plastic. When the elastic arm 22 is made of metal, the first groove 221 and the second groove 222 can reduce the weight and cost of the elastic arm 22. When the elastic arm 22 is made of plastic, the first groove 221 and the second groove 222 can reduce the thickness of the elastic arm 22, thereby reducing the injection defects such as depression, hollowness, and deformation caused by the excessive thickness of the plastic elastic arm 22.

[0064] The shapes of the first groove 221 and the second groove 222 are not limited and can be set according to the shape of the elastic arm 22. For example, the first groove 221 is rectangular or square. In order to facilitate demoulding, the cross-sectional area of ​​the second groove 222 gradually decreases along the depth direction of the second groove 222. For example, the second groove 222 is trapezoidal.

[0065] In an exemplary embodiment, the first groove 221 and / or the second groove 222 are arranged at intervals along the length direction of the elastic arm 22. The first groove 221 and / or the second groove 222 are arranged at intervals along the length direction of the elastic arm 22 to avoid a decrease in the strength of the elastic arm 22.

[0066] The number of the first groove 221 and the second groove 222 is not limited, and can be one, two or three. Figure 4 and Figure 5 As shown, there are five first grooves 221 and one second groove 222. The first grooves 221 and the second grooves 222 are arranged at intervals along the length direction of the elastic support arm 22. The outer side wall of the elastic support arm 22 is provided with three first grooves 221, and the inner side wall of the elastic support arm 22 is provided with one second groove 222 and two first grooves 221.

[0067] Similarly, in order to reduce the weight of the support member 21 or reduce injection defects, in an exemplary embodiment, a third groove 211 is provided on the support member 21. The shape and number of the third groove 211 are not limited. Figure 5 As shown, the number of the third grooves 211 is three, and the cross-sectional areas of the third grooves 211 along the depth direction of the third grooves 211 are the same.

[0068] In an exemplary embodiment, referring to Figure 1 and Figure 3 The connection angle code 10 also includes a first fixing portion 6 and a second fixing portion 7. One end of the first fixing portion 6 is connected to the first port 11 of the first connecting sleeve, and the other end of the first fixing portion 6 is connected to the clamping portion 2.
