Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module frame technology, and specifically relates to a novel photovoltaic module frame. Background Technology

[0002] Currently, most solar photovoltaic modules are symmetrically assembled using long-side aluminum frames and short-side aluminum frames. This means that after being cut at a 45° angle, the cross-sectional structure of adjacent sides of the photovoltaic module frame is made consistent. Then, the frame is installed around the solar photovoltaic panel using corner keys and other assembly methods to form a complete solar photovoltaic module.

[0003] With the rapid development of the photovoltaic industry and the diversification of application scenarios for double-glass modules, their application in many scenarios such as curtain wall installation, marine installation, and industrial and commercial applications is becoming increasingly widespread. However, conventional frame applications are often wasteful, heavy, and have poor compatibility in specific scenarios. In particular, the development of offshore photovoltaics has been particularly rapid in recent years. In order to better accommodate floating photovoltaics at sea, it is especially important to develop frames that adapt to new products to meet installation requirements.

[0004] Based on the problems of symmetrical solar module frames, a novel solar photovoltaic module disclosed in Chinese patent application No. 201620641770.9 adopts an asymmetrical frame for its aluminum alloy frame, that is, the cross-sectional area of ​​the short frame is smaller than the cross-sectional area of ​​the long frame.

[0005] The asymmetrical frame provided by the aforementioned patent reduces the cross-sectional size of the short frame profile by changing the cutting angle or shortening the width of the mating edge, thereby reducing the material used in the short frame, lowering the frame weight and cost.

[0006] However, the asymmetrical frame of this structure has inconsistent splicing edge lengths on the joint surfaces when assembling adjacent frames, resulting in a mismatch at the inner corner splicing points. This creates non-90° angle gaps, leaving gaps in the frame assembly. This not only affects the aesthetics but also severely impacts the assembly effect of the solar photovoltaic modules, reducing the structural integrity of the modules, significantly decreasing the protection provided by the frame, and even potentially shortening the lifespan of the solar photovoltaic modules. Utility Model Content

[0007] The purpose of this invention is to provide a novel photovoltaic module frame to solve the problems mentioned in the background section. The novel photovoltaic module frame provided by this invention features low material usage, light weight, low cost, and good stability.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a novel photovoltaic module frame, comprising a frame body symmetrically mounted on the two long sides of the photovoltaic module, the frame body comprising a U-shaped frame, the U-shaped frame comprising a lower stop edge and an upper stop edge, wherein the width of the upper stop edge is smaller than the width of the lower stop edge, and a connecting edge is provided on one side of the U-shaped frame.

[0009] Furthermore, the frame itself is made of aluminum alloy.

[0010] Furthermore, the length of the frame body is less than or equal to the length of the long side of the photovoltaic module.

[0011] To effectively reduce the scrap rate of photovoltaic modules during installation, a first rounded corner is provided above the outer edge of the lower stop. A second rounded corner is provided below the outer edge of the upper stop.

[0012] To reduce the stress caused by the contact between the photovoltaic module and the frame body, and thus effectively protect the photovoltaic module, a third rounded corner is provided at the corner inside the U-shaped frame.

[0013] To facilitate installation via hooks, bolts, ropes, or brackets, and to accommodate various installation methods and scenarios, several mounting holes are provided on the connecting edge. Each mounting hole has rounded corners on both sides.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model eliminates the short frame design and uses only two frame bodies to install photovoltaic modules, saving the material used for the short frame, reducing the overall weight of the frame and production costs.

[0016] 2. The lower and upper edges of the frame body of this utility model adopt an asymmetrical design. The lower edge is located on the back of the photovoltaic module, which ensures the load-bearing capacity of the photovoltaic module.

[0025] Example 1

[0026] Please see Figures 1-3 The present invention provides the following technical solution: a novel photovoltaic module frame, comprising a frame body 2 symmetrically installed on the two long sides of a photovoltaic module 1, the frame body 2 being made of aluminum alloy, the frame body 2 comprising a U-shaped frame 3, the U-shaped frame 3 comprising a lower stop edge 4 and an upper stop edge 5, wherein the width of the upper stop edge 5 is less than the width of the lower stop edge 4, the length of the frame body 2 is less than or equal to the length of the long side of the photovoltaic module 1, and a connecting edge 6 is provided on one side of the U-shaped frame 3.

[0027] By adopting the above technical solution, the present invention eliminates the design of the short frame and only uses two frame bodies 2 to install the photovoltaic module 1, saving the material of the short frame and reducing the overall weight and production cost of the frame; the lower stop 4 and the upper stop 5 of the frame body 2 of the present invention adopt an asymmetrical design, with the lower stop 4 located on the back of the photovoltaic module 1, ensuring the load-bearing capacity of the photovoltaic module 1.

[0028] Example 2

[0029] The difference between this embodiment and embodiment 1 is that: specifically, a first rounded corner 8 is provided above the outer side of the lower stop 4, and a second rounded corner 9 is provided below the outer side of the upper stop 5.

[0030] By adopting the above technical solution, the scrap rate of photovoltaic module 1 during the installation process can be effectively reduced.

[0031] Example 3

[0032] The difference between this embodiment and embodiment 1 is that, specifically, a third rounded corner 10 is provided at the corner inside the U-shaped frame 3.

[0033] By adopting the above technical solution, the stress caused by the contact between the photovoltaic module 1 and the frame body 2 can be reduced, thereby effectively protecting the photovoltaic module 1.

[0036] By adopting the above technical solutions, installation can be carried out using hooks, bolts, ropes, or brackets, which are compatible with a variety of installation methods and meet more installation scenarios.

[0037] In this invention, when a gain is required for back-side power generation: the width of the lower edge 4 is less than or equal to the safe creepage distance, so it will not block the photovoltaic module 1, and can increase the load strength of the photovoltaic module 1 during the load-bearing process.

[0038] When the back-side power generation gain is not required: the width of the lower edge 4 is greater than the safe creepage distance, which can ensure that the photovoltaic module 1 and the frame body 2 have more contact surface and improve load capacity.

[0039] In summary, this utility model eliminates the short frame design, using only two frame bodies 2 to install the photovoltaic module 1, saving on the material used for the short frame and reducing the overall weight and production cost of the frame. The lower stop 4 and upper stop 5 of the frame body 2 of this utility model adopt an asymmetrical design, with the lower stop 4 located on the back of the photovoltaic module 1, ensuring the load-bearing capacity of the photovoltaic module 1. The lower stop 4 has a first rounded corner 8 above its outer side, and the upper stop 5 has a second rounded corner 9 below its outer side, which can effectively reduce the scrap rate of the photovoltaic module 1 during installation.
