Description

Technical Field

[0001] This utility model relates to the frame of a photovoltaic module, specifically a photovoltaic module without a C-side frame. Background Technology

[0002] The absence of a C-side frame in the market reduces stability, making it prone to instability and wobbling when supporting and installing photovoltaic modules. Furthermore, the removal of the C-side frame makes it inconvenient for workers to move the equipment as there is nowhere to grip it. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a photovoltaic module without a C-side frame. This utility model offers better stability by utilizing corner codes to ensure the stability and tightness between the long and short frames, and is convenient to use and transport.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a photovoltaic module without a C-side frame, comprising an inner frame, an outer frame, an upper support frame, and a lower support frame. The inner frame, the outer frame, the upper support frame, and the lower support frame form a square and form corner grooves, with corner brackets installed in the corner grooves. The inner frame has a concave surface, and the outer frame has a slot. The top of the outer frame is provided with an upper frame for fixing the photovoltaic module, and the bottom is provided with a lower frame for fixing.

[0005] The concave surface is an inwardly recessed triangle.

[0006] The slot is flush with the middle of the inner frame, and folded edges are provided on both the upper and lower sides of the slot, with the folded edges extending outward.

[0007] The lower surface of the upper support frame is provided with a first reinforcing rib, and the upper surface of the lower support frame is provided with a second reinforcing rib.

[0008] The lower frame has bolt holes.

[0009] The corner bracket includes an outer frame, a connecting frame, and a middle frame. One end of the connecting frame is connected to the middle of the outer frame, and the other end is connected to the middle of one side of the middle frame. Both ends of the outer frame are provided with locking edges, which are respectively engaged with the folded edge. The connecting frame is located in the slot, and the middle frame is located in the corner slot.

[0010] The middle frame has an open slot, and the outer wall of one side of the middle frame opposite to the connecting frame has a triangular slot.

[0011] The outer wall of the middle frame has a groove.

[0012] In summary, this utility model achieves the following technical effects:

[0013] This utility model has a slot on the outer frame to install corner brackets. At the same time, the entire frame can be moved by reaching into the slot. The inner frame 1 has a concave surface to enhance the support. The corner brackets make it easy to connect the long and short frames. The lower frame 5 is used to fix the entire component.

[0014] This invention offers better stability by utilizing corner brackets to ensure stability and tightness between the long and short borders, making it convenient to use and transport. Attached Figure Description

[0024] Example:

[0025] Figure 1 A photovoltaic module without a C-side frame is provided, comprising an inner frame 1, an outer frame 2, an upper support frame 3, and a lower support frame 4. The inner frame 1, the outer frame 2, the upper support frame 3, and the lower support frame 4 form a square and form corner grooves 6. Corner brackets 7 are installed in the corner grooves 6. The inner frame 1 has a concave surface 11, and the outer frame 2 has a slot 21. The top of the outer frame 2 is provided with an upper frame for fixing the photovoltaic module, and the bottom is provided with a lower frame 5 for fixing.

[0026] This utility model has a slot in the outer frame 2 to install corner brackets. At the same time, the entire frame can be moved by reaching into the slot. The inner frame 1 has a concave surface to enhance the support. The corner brackets make it easy to connect the long and short frames. The lower frame 5 is convenient for fixing the entire component.

[0027] This invention offers better stability by utilizing corner brackets to ensure stability and tightness between the long and short borders, making it convenient to use and transport.

[0028] The concave surface 11 is an indented triangle.

[0029] The triangular structure provides greater stability and improves the overall stability of the device. The inward-curving triangular structure will not interfere with the installation of the photovoltaic modules or cause injury to workers.

[0030] The slot 21 is flush with the middle of the inner frame 1, and the upper and lower sides of the slot 21 are provided with folded edges 22, which extend outward.

[0031] The slot 21 is positioned in the middle to enhance balance and facilitate handling. The folded edge 22 makes it easy to hold and move, and also strengthens the connection with the corner bracket 7, resulting in a more stable connection.

[0032] The lower surface of the upper support frame 3 is provided with a first reinforcing rib 31, and the upper surface of the lower support frame 4 is provided with a second reinforcing rib 41. The two reinforcing ribs improve stability.

[0033] The lower frame 5 has bolt holes 51 for easy fixing of the entire device.

[0034] Figure 2 This is a schematic diagram of a corner code. The corner code 7 includes an outer frame 71, a connecting frame 72, and a middle frame 74. One end of the connecting frame 72 is connected to the middle of the outer frame 71, and the other end is connected to the middle of one side of the middle frame 74. Both ends of the outer frame 71 are provided with locking edges 73, which are respectively engaged with the folded edge 22. The connecting frame 72 is located in the slot 21, and the middle frame 74 is located in the corner slot 6.

[0035] This utility model is equipped with corner brackets 7, which can easily connect long and short frames. The middle frame 74 serves as the main connector to improve the strength and stability of the connection. The connecting frame 72 can extend into the slot. The outer frame 71 and the edge clip 73 strengthen the tightness between the corner bracket and the frame, making it less likely to detach or loosen. At the same time, after the long and short frames are installed, the edge clip 73 can be held by hand for easy handling.

[0036] The middle frame 74 has a hollow groove 77, and a triangular groove 76 is formed on the outer wall of one side of the middle frame 74 opposite to the connecting frame 72. The hollow groove 77 can reduce weight, and the triangular groove 76 can cooperate with the concave surface 11.

[0037] The outer wall of the middle frame 74 has a groove 75, which cooperates with the first reinforcing rib 31 and the second reinforcing rib 41. The groove also increases the stability of the corner bracket.

[0038] Figure 3 This is a diagram illustrating the corner bracket being connected to the border.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
