[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] Please refer to Figures 1-4 , Figure 1 This is a structural schematic diagram of the photovoltaic corner bracket 100 provided in this embodiment; Figure 2 This is a schematic diagram of the structure of the photovoltaic frame 200 provided in this embodiment; Figure 3 This is a schematic diagram of the structure of the connected photovoltaic frame 210 provided in this embodiment; Figure 4 This is a schematic diagram of the structure of the photovoltaic frame 210 before connection provided in this embodiment.

[0036] This embodiment of the invention provides a photovoltaic frame 200, which includes a plurality of photovoltaic corner brackets 100 and a plurality of photovoltaic frame pieces 210. The photovoltaic corner brackets 100 and the photovoltaic frame pieces 210 are connected in sequence to enclose a cavity for accommodating photovoltaic modules. Understandably, each photovoltaic corner bracket 100 is connected to two photovoltaic frame pieces 210, and each photovoltaic frame piece 210 is also connected to two photovoltaic corner brackets 100. The number of photovoltaic corner brackets 100 and photovoltaic frame pieces 210 is the same.

[0037] Specifically, in this embodiment, the photovoltaic frame 200 includes four photovoltaic corner brackets 100 and four photovoltaic frame 210, and the accommodating cavity is formed by the four photovoltaic corner brackets 100 and the photovoltaic frame 210.

[0038] It should be noted that the photovoltaic frame 210 in this embodiment includes a first sidewall 211, a second sidewall 213, and a third sidewall 214. The first sidewall 211 and the second sidewall 213 are arranged opposite to each other and are respectively connected to both sides of the third sidewall 214. The first sidewall 211, the second sidewall 213, and the third sidewall 214 enclose a cavity 201, into which the photovoltaic corner bracket 100 can extend to connect with the photovoltaic frame 210. Specifically, the first sidewall 211 and the second sidewall 213 are both perpendicular to the third sidewall 214.

[0039] Understandably, since the cavity 201 is formed by the first sidewall 211, the second sidewall 213 and the third sidewall 214, the cavity 201 in the cross section of the photovoltaic frame 210 in this embodiment is different from the closed shape in the prior art, but has an open shape.

[0040] The frame in the prior art also includes a fourth sidewall, which is arranged opposite to the third sidewall and is connected to the first sidewall and the second sidewall on both sides respectively. The cavity of the frame in the prior art is formed by the first sidewall, the second sidewall, the third sidewall and the fourth sidewall. The cavity of the cross section of the frame in the prior art is a closed shape.

[0041] Existing technologies generally employ the method of machining rivets on the fourth side wall to fix the corner brackets. The frame is secured by the interlocking teeth structure of the rivets and the corner brackets.

[0042] However, with the continuous optimization of the structure of the photovoltaic frame 210, the photovoltaic frame 210 in this embodiment does not have a fourth sidewall, so as to reduce the weight of the photovoltaic frame 210 and thus reduce the overall cost.

[0043] Therefore, this embodiment provides a photovoltaic corner bracket 100 to adapt to the photovoltaic frame 210. The photovoltaic corner bracket 100 in this embodiment includes two connecting parts 110, which are connected at an angle; each connecting part 110 is used to connect to the cavity 201 of the photovoltaic frame 210.

[0044] It should be noted that, since there are four photovoltaic frame 210 and four photovoltaic corner brackets 100 in this embodiment, the photovoltaic frame 200 in this embodiment is a square structure, so the two connecting parts 110 are perpendicular to each other.

[0045] The two connecting parts 110 can extend into the cavities 201 of the two photovoltaic frames 210 respectively, so that each connecting part 110 can be accommodated in the cavity 201 of a photovoltaic frame 210. Therefore, the photovoltaic corner bracket 100 contacts the first sidewall 211, the second sidewall 213 and the third sidewall 214 that form the corresponding cavity 201.

[0046] After the connecting part 110 extends into the cavity 201, the first side wall 211 is stamped using a stamping machine, so that the first side wall 211 has a protrusion 212; since the connecting part 110 even has a through hole 111, the protrusion 212 formed after stamping can engage with the through hole 111, thereby connecting the photovoltaic corner bracket 100 to the photovoltaic frame 210 to form a photovoltaic frame 200, improving the stability of the installation of the photovoltaic corner bracket 100 and the photovoltaic frame 210.

[0047] Understandably, in this embodiment, the axial direction of the through hole 111 is parallel to the height direction of the connecting portion 110. The protrusion 212 protrudes in the direction of the connecting portion 110.

[0048] It should be noted that in this embodiment, multiple through holes 111 are provided, and the multiple through holes 111 are arranged at intervals along the length direction of the connecting part 110. The stamping machine stamps the first sidewall 211 to form multiple protrusions 212. Each through hole 111 corresponds to one protrusion 212 and engages with the corresponding protrusion 212, thereby improving the stability of installation.

[0049] Based on the above, the photovoltaic frame 210 in this embodiment further includes a limiting portion 215. The limiting portion 215 is connected to the side of the first sidewall 211 away from the third sidewall 214 and is disposed opposite to the third sidewall 214; the limiting portion 215 is spaced apart from the second sidewall 213. Since the first sidewall 211 and the second sidewall 213 are perpendicular to the third sidewall 214, the limiting portion 215 is perpendicular to both the first sidewall 211 and the second sidewall 213.

[0050] Therefore, in this embodiment, the position of the photovoltaic corner bracket 100 is restricted by the limiting part 215 to prevent the photovoltaic corner bracket 100 from detaching from the photovoltaic frame 210 from the opening on the side of the photovoltaic frame 210, thereby improving the stability of the installation of the photovoltaic frame 210 and the photovoltaic corner bracket 100 and strengthening the structural strength of the photovoltaic frame 200.

[0051] Furthermore, in this embodiment, a groove 112 is provided on the inner side where the two connecting parts 110 intersect; wherein, the opening direction of the groove 112 is perpendicular to the axial direction of the through hole 111.

[0052] Since the two connecting parts 110 extend into the cavities 201 of different photovoltaic frames 210 respectively, in order to avoid the two photovoltaic frames 210 colliding with each other or affecting the installation between the other photovoltaic frame 210 and the photovoltaic corner bracket 100, this embodiment provides a groove 112 to provide adjustment space, so as to finely adjust the position of the photovoltaic frame 210 and the photovoltaic corner bracket 100, so that the photovoltaic corner bracket 100 can be smoothly connected to the photovoltaic frame 210.

[0053] It should be noted that during the process of connecting the photovoltaic frame 210, since the inner and outer walls of the photovoltaic frame 210 are of equal length, the inner walls of the two photovoltaic frames 210 will contact each other. Therefore, the groove 112 needs to be set on the inside of the corner bracket to avoid the two photovoltaic frames 210 from obstructing each other.

[0054] Understandably, in this embodiment, the limiting part 215 is a side wall, while the third side wall 214 is an outer side wall.

[0055] In this embodiment, the through hole 111 engages with the protrusion 212 of the first sidewall 211, indicating that the axial direction of the through hole 111 is perpendicular to the first sidewall 211. The groove 112 needs to provide adjustment space to prevent the two limiting parts 215 from colliding and hindering the installation of the photovoltaic corner bracket 100 and the photovoltaic frame 210. Therefore, it can be deduced that the opening direction of the groove 112 must be perpendicular to the limiting part 215, so the axial direction of the through hole 111 is perpendicular to the opening direction of the groove 112. Furthermore, in this embodiment, the axial direction of the through hole 111 is parallel to the extending direction of the groove 112.

[0056] According to the above, the photovoltaic corner code 100 in this embodiment also includes two guide portions 120, which are respectively connected to two connecting portions 110 and located at the end of the corresponding connecting portion 110 away from the other connecting portion 110.

[0057] Understandably, the guide portion 120 first enters the cavity 201 of the photovoltaic frame 210, and then the connecting portion 110 enters the cavity 201 of the photovoltaic frame 210. To improve installation convenience, the cross-sectional area of ​​the guide portion 120 in the height direction of the connecting portion 110 gradually decreases in the direction away from the other connecting portion 110, so that the guide portion 120 can guide the connecting portion 110 to move into the cavity 201, thereby smoothly connecting the photovoltaic corner bracket 100 and the photovoltaic frame 210 together, so as to facilitate the installation of the photovoltaic frame 200.

[0058] In summary, the photovoltaic corner bracket 100 in this embodiment connects to the photovoltaic frame 210 via two connecting portions 110 to form a photovoltaic frame 200. The connecting portions 110 have through holes 111 for engaging with protrusions 212 on the photovoltaic frame 210, thereby improving the stability of the photovoltaic corner bracket 100 and the photovoltaic frame 210 during installation. Furthermore, the photovoltaic corner bracket 100 in this embodiment provides adjustment space by incorporating grooves 112, preventing the two photovoltaic frames 210 connected to the photovoltaic corner bracket 100 from colliding with each other, thus improving the ease of installation of the photovoltaic corner bracket 100 and the photovoltaic frame 210.

[0059] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
