[0046] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0047] 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.

[0048] Please refer to Figures 1-3 , Figure 1 This is a schematic diagram of the structure of the corner code 100 provided in this embodiment; Figure 2 This is a schematic diagram of the structure of the main body 110 provided in this embodiment; Figure 3 for Figure 1 A magnified view of a portion of point A in the middle.

[0049] This embodiment provides a corner bracket 100, which includes a main body 110 and two connecting parts 130. The main body 110 is provided with a first receiving groove 101, and the bottom of the first receiving groove 101 is provided with at least one first anti-overflow adhesive groove 102. The two connecting parts 130 are connected to the main body 110 at an angle. The first receiving groove 101 is used to receive the corner of the photovoltaic module 310. The two connecting parts 130 are respectively inserted into a photovoltaic frame 210.

[0050] Specifically, the corner bracket 100 protects the corner of the photovoltaic module 310 by providing a first receiving groove 101 to accommodate the corner, thus preventing damage from external forces. It should be noted that after the corner of the photovoltaic module 310 is accommodated in the first receiving groove 101, adhesive needs to be applied for bonding. However, during the adhesive application process, excess adhesive may overflow and obstruct the surface of the photovoltaic module 310. Therefore, in this embodiment, a first anti-overflow adhesive groove 102 is provided at the bottom of the first receiving groove 101, allowing excess adhesive to be contained within the first anti-overflow adhesive groove 102, thereby preventing adhesive from obstructing the photovoltaic module 310 and improving power generation and efficiency.

[0051] In this embodiment, the corner bracket 100 is also provided with two connecting parts 130 that are connected to the main body 110 at an angle, so that the corner bracket 100 can be connected to the photovoltaic frame 210 to form a photovoltaic frame 200, thereby improving the protection effect on the photovoltaic module 310.

[0052] It should be noted that the photovoltaic module 310 in this embodiment includes a photovoltaic panel and a laminate, etc. The photovoltaic panel is disposed in the laminate, which is made of a transparent material, so the photovoltaic panel can absorb solar energy to generate electricity; and the structure in contact with the corner bracket 100 is the laminate.

[0053] Based on the above settings, please refer to... Figures 1-3 The corner code 100 also includes a limiting plate 120, which is connected to the end of the main body 110 and together forms a first receiving groove 101; the limiting plate 120 is provided with an arc-shaped clearance notch 121, which is provided along the outer edge of the corner of the photovoltaic module 310.

[0054] Specifically, in this embodiment, the limiting plate 120 is connected to the upper end of the main body 110, and the upper end surfaces of the limiting plate 120 and the main body 110 are spaced apart, thereby forming a first receiving groove 101 to accommodate the corner of the photovoltaic module 310, and the limiting plate 120 restricts the downward movement of the photovoltaic module 310 to prevent the photovoltaic module 310 from falling off.

[0055] In this embodiment, the limiting plate 120 is provided with an arc-shaped clearance notch 121 to reduce the shading area of ​​the limiting plate 120 on the surface of the photovoltaic module 310, thereby improving the power generation and power generation efficiency of the photovoltaic module 310.

[0056] Further, please refer to Figures 1-7 , Figure 4 This is a schematic diagram of the photovoltaic frame 200 provided in this embodiment from a first-view perspective; Figure 5 This is an exploded view of the photovoltaic frame 200 provided in this embodiment from a second perspective; Figure 6 This is a schematic diagram of the photovoltaic frame 210 from a first-view perspective provided in this embodiment; Figure 7 This is a schematic diagram of the photovoltaic frame 210 from a second perspective in this embodiment.

[0057] This embodiment provides a photovoltaic frame 200, which includes at least two photovoltaic frame edges 210 and at least one corner bracket 100. Each photovoltaic frame edge 210 has a cavity 201, and each connecting part 130 is inserted into a cavity 201 of a photovoltaic frame edge 210.

[0058] Understandably, when the corner bracket 100 and the photovoltaic frame 210 are connected together to form the photovoltaic frame 200, the connecting part 130 of the corner bracket 100 is located inside the cavity 201 and is connected to the inner wall of the cavity 201. Each corner bracket 100 is inserted into one end opening of the corresponding cavity 201, and the connecting parts 130 of different corner brackets 100 are inserted into the two end openings of the same cavity 201 respectively.

[0059] In this embodiment, since the photovoltaic module 310 has a square structure, four corner brackets 100 and four photovoltaic frames 210 are provided. The four photovoltaic frames 210 are connected end to end through the corner brackets 100 to form a square frame for surrounding and fixing the photovoltaic module 310.

[0060] In other embodiments, the photovoltaic module 310 may also be an irregularly shaped structure, so the number of corner brackets 100 and photovoltaic frame 210 can be adaptively adjusted according to the shape of the photovoltaic module 310.

[0061] Similarly, in this embodiment, the included angle between the two connecting portions 130 of the corner bracket 100 is a right angle. In other embodiments, the included angle between the two connecting portions 130 can be adjusted according to the shape of the photovoltaic module 310.

[0062] According to the above configuration, the photovoltaic frame 210 includes a supporting part 212 and a frame 211. The supporting part 212 and the frame 211 are connected on one side, and the side of the frame 211 near the supporting part 212 together with the supporting part 212 forms a second receiving groove 202. The second receiving groove 202 is used to receive the outer edge of the photovoltaic module 310. The second receiving groove 202 is connected to the first receiving groove 101. The inner wall of the supporting part 212 is provided with a second anti-overflow glue groove 213, and the side of the frame 211 near the supporting part 212 is provided with a third anti-overflow glue groove 214.

[0063] Understandably, in order for the photovoltaic frame 200 to wrap around the outer edge of the photovoltaic module 310, the photovoltaic frame 210 is provided with a second receiving groove 202 communicating with the first receiving groove 101 to receive the outer edge of the photovoltaic module 310. Similarly, in order to prevent the glue from overflowing during the glue application process and affecting the power generation and efficiency of the photovoltaic module 310, a second anti-overflow glue groove 213 and a third anti-overflow glue groove 214 are provided to receive the glue that flows under pressure, preventing the glue from overflowing onto the photovoltaic module 310 and preventing the glue from blocking the photovoltaic module 310, thereby improving the power generation and efficiency of the photovoltaic module 310.

[0064] Furthermore, in this embodiment, the two photovoltaic frames 210 are connected together by corner brackets 100, which avoids the formation of gaps when the two photovoltaic frames 210 are directly connected, thus preventing dust accumulation on the photovoltaic module 310. This avoids dust blocking the photovoltaic module 310, improves power generation and efficiency, and enables a full-screen module.

[0065] It should be noted that in this embodiment, the first anti-overflow adhesive groove 102 extends horizontally to prevent adhesive from overflowing onto the photovoltaic module 310. The second anti-overflow adhesive groove 213 and the third anti-overflow adhesive groove 214 extend along the length of the frame 211 to prevent adhesive from flowing into the photovoltaic module 310 and overflowing, thus preventing the adhesive from blocking the photovoltaic module 310.

[0066] Further, please refer to Figures 1-9 , Figure 8 This is a schematic diagram of the structure of the photovoltaic device 300 provided in this embodiment; Figure 9 A schematic diagram of the structure of a photovoltaic device 300 provided for other embodiments.

[0067] This embodiment provides a photovoltaic device 300, which includes a photovoltaic module 310 and a photovoltaic frame 200. The corner of the photovoltaic module 310 is accommodated in a first accommodating groove 101, and the edge of the photovoltaic module 310 is accommodated in a second accommodating groove 202.

[0068] It should be noted that, since the surface of the photovoltaic module 310 is smooth, the surface of the corner bracket 100 that contacts the photovoltaic module 310 and the surface of the photovoltaic frame 210 that contacts the photovoltaic module 310 are on the same plane. Understandably, the surface of the main body 110 that contacts one side of the photovoltaic module 310 is the corner bracket contact surface 111; the surface of the frame 211 that contacts one side of the photovoltaic module 310 is the frame contact surface 215; the frame contact surface 215 is provided with a third anti-overflow adhesive groove 214; wherein, both the corner bracket contact surface 111 and the frame contact surface 215 abut against the same side of the photovoltaic module 310.

[0069] In this embodiment, the corner code contact surface 111 is the upper surface of the main body 110, the frame contact surface 215 is the upper surface of the photovoltaic frame 210, and the sides of the photovoltaic module 310 that contact the corner code contact surface 111 and the frame contact surface 215 are the lower surfaces of the photovoltaic module 310.

[0070] Furthermore, in this embodiment, the photovoltaic module 310 has a square structure, and the top of the outer wall of the limiting plate 120 and the top of the supporting part 212 are located in the same plane.

[0071] It should be noted that the position where the limiting plate 120 abuts against the photovoltaic module 310 is the first abutting surface 122, and the position where the supporting part 212 abuts against the photovoltaic module 310 is the second abutting surface 216. Specifically, the first abutting surface 122 abuts against the side of the photovoltaic module 310 near the arc-shaped clearance notch 121, and the second abutting surface 216 abuts against the side of the photovoltaic module 310 near the supporting part 212. Understandably, the first abutting surface 122 abuts against the side of the photovoltaic module 310 opposite to the frame contact surface 215.

[0072] Specifically, in this embodiment, the first abutting surface 122 abuts against the upper surface of the photovoltaic module 310, while the second abutting surface 216 abuts against the side surface of the photovoltaic module 310. Understandably, since the corners of the square photovoltaic module 310 are right angles, these right angles are easily damaged by external forces. Therefore, the limiting member is made to contact the upper surface of the photovoltaic module 310 to improve the protection of the corners.

[0073] In other embodiments, the photovoltaic module 310 has a circular structure, and the top of the inner wall of the limiting plate 120 and the top of the supporting part 212 are located on the same plane.

[0074] It should be noted that the position where the limiting plate 120 abuts against the photovoltaic module 310 is the first abutting surface 122, and the position where the supporting part 212 abuts against the photovoltaic module 310 is the second abutting surface 216; wherein, the first abutting surface 122 abuts against the side of the photovoltaic module 310 at the corner; and the second abutting surface 216 abuts against the side of the photovoltaic module 310 near the supporting part 212.

[0075] Specifically, in other embodiments, both the first contact surface 122 and the second contact surface 216 abut against the arcuate side of the circular photovoltaic module 310. This reduces the shading area of ​​the limiting plate 120 on the photovoltaic module 310, thereby increasing power generation and efficiency.

[0076] Further, please refer to Figures 1-9 In this embodiment, at least one side of each connecting part 130 is provided with an anti-slip protrusion 131, and the anti-slip protrusion 131 is located in the part of the connecting part 130 used for insertion into the photovoltaic frame 210; the anti-slip protrusion 131 abuts against the inner wall of the photovoltaic frame 210.

[0077] In this embodiment, the side wall of the connecting part 130 with the largest contact area with the photovoltaic frame 210 is provided with anti-slip protrusions 131, thereby increasing the anti-slip effect and preventing the corner bracket 100 from detaching from the photovoltaic frame 210, which would cause the photovoltaic frame 200 formed by the photovoltaic frame 210 and the corner bracket 100 to fall apart, thus failing to protect the photovoltaic module 310 and causing damage to the photovoltaic module 310.

[0078] According to the above configuration, each connecting part 130 is provided with a through hole 132. In this embodiment, the axis of the through hole 132 is vertical, thereby ensuring the contact area between the anti-slip protrusion 131 and the inner wall of the photovoltaic frame 210, reducing the weight of the corner bracket 100, alleviating the stress on the photovoltaic bracket and increasing the structural strength.

[0079] In summary, the corner bracket 100 in this embodiment includes a main body 110 and two connecting parts 130. The main body 110 is provided with a first receiving groove 101, and the bottom of the first receiving groove 101 is provided with at least one first anti-overflow adhesive groove 102. The two connecting parts 130 are connected to the main body 110 at an angle. The first receiving groove 101 is used to receive the corner of the photovoltaic module 310. The two connecting parts 130 are respectively connected to a photovoltaic frame 210.

[0080] The corner bracket 100 is configured with a first receiving groove 101 to accommodate the corner of the photovoltaic module 310, thereby protecting the corner position of the photovoltaic module 310 and preventing damage to the photovoltaic module 310. The bottom of the first receiving groove 101 is provided with a first anti-overflow adhesive groove 102, so that the adhesive flowing due to the mutual compression between the corner bracket 100 and the photovoltaic module 310 during the adhesive application process can be contained in the first anti-overflow adhesive groove 102, thereby preventing the adhesive from overflowing onto the photovoltaic module 310 and shielding the photovoltaic module 310, thus avoiding any impact on the power generation and power generation efficiency of the photovoltaic module 310.

[0081] 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.
