Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic frame with a universal photovoltaic angle code. Background Art

[0002] With the increasing demand for renewable energy and the drive for building sustainability, building-integrated photovoltaic (BIPV) technology is rapidly developing. BIPV not only provides green energy solutions but also seamlessly integrates photovoltaic systems into architectural designs, achieving a perfect marriage of aesthetics and functionality. In recent years, irregularly shaped photovoltaic modules have become increasingly popular. Their unique appearance and design meet the high demands of architectural design for both individuality and aesthetics. Irregular modules can adapt to complex building surfaces, enhancing the overall aesthetic value of the building while also increasing the power generation efficiency of the photovoltaic system. While this trend provides more options for architectural design, it also presents new challenges for related accessories, such as corner brackets.

[0003] In the installation of traditional BIPV systems, corner brackets, as key components connecting photovoltaic modules to building structures, are usually designed with fixed angles. These fixed-angle corner brackets show obvious shortcomings when dealing with irregular modules. In order to accommodate modules with different angles, the corresponding corner brackets must be customized, and the frame needs to be cut. This not only increases the complexity of production and installation, but also significantly increases costs. Each module with a different angle requires the manufacture of a specific corner bracket, resulting in inefficient operation of the production line and increased production and transportation time costs. At the same time, the need for customized corner brackets makes the logistics and installation process more cumbersome, increasing the overall cost of transportation and construction. This situation not only affects the economic feasibility of the project, but also limits the popularization and application of BIPV technology. Utility Model Content

[0011] Furthermore, the intermediate connecting member includes a central protrusion provided at the center of the upper substrate and a central ring provided at the center of the lower substrate, wherein the central protrusion is embedded in the central ring;

[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] Example:

[0040] like Figures 1 to 6 As shown, a photovoltaic frame with universal photovoltaic angle brackets includes: a frame 1 and a fixed angle bracket 2 provided on the frame 1, and adjacent frames 1 are connected by the fixed angle bracket 2. In this embodiment, the fixed angle bracket 2 is made of one of ABS, PETG, nylon, and PLA.

[0041] The fixed corner bracket 2 comprises an upper structure 3 and a lower structure 4. The upper structure 3 includes a first corner bracket body 31 connected to the frame 1, an upper base plate 32, and a plurality of upper protrusions 33 disposed on the upper base plate 32. The upper protrusions 33 are arranged in a circular shape and spaced evenly on the upper base plate 32. The lower structure 4 includes a second corner bracket body 41 connected to the frame 1, a lower base plate 42, and a plurality of lower grooves 43 disposed on the lower base plate 42. The lower grooves 43 are arranged in a circular shape and spaced evenly on the lower base plate 42, with the protrusions embedded in the grooves. In this embodiment, the number of upper protrusions 33 and lower grooves 43 ranges from 6 to 360. This embodiment uses six upper protrusions 33 and six lower grooves 43, allowing the frame 1 to be adjusted 60 degrees.

[0042] like Figures 1 to 6As shown, an intermediate connector 5 is provided at the center of the upper structure 3 and the center of the lower structure 4 to connect the upper structure 3 and the lower structure 4. The intermediate connector 5 includes a central protrusion 52 provided at the center of the upper base plate 32 and a central ring 51 provided at the center of the lower base plate 42. The central protrusion 52 is embedded in the central ring 51. A limit plate 521 extends inward from the bottom of the center ring 51. The central protrusion 52 abuts against the limit plate 521. The limit plate 521 defines a first fixing groove 53. A second fixing groove 54 is defined at the center of the central protrusion 52. The limit plate 521 has a plurality of first ribs 55 protruding toward the first fixing groove 53. The central protrusion 52 has a plurality of second ribs 56 protruding from the second fixing groove 54. The first ribs 55 and the second ribs 56 are arranged opposite each other. A fixing pin 6 is inserted into the first fixing groove 53 and the second fixing groove 54. By inserting the fixing pin 6 into the first fixing groove 53 and the second fixing groove 54, and by engaging the fixing pin 6 with the first rib 55 and the second rib 56, the angle between the frame 1 can be adjusted and fixed by the position of the first rib 55 and the second rib 56 in the fixing groove. In this embodiment, the fixing pin 6 and the first fixing groove 53 and the second fixing groove 54 are connected by interference fit, thereby securing the fixing pin 6 in the first fixing groove 53 and the second fixing groove 54 and reducing the possibility of the fixing pin 6 falling off.

[0043] like Figures 1 to 6 As shown, a corner protector 7 covering and fixing the corner code piece 2 is provided on the frame 1 , and the corner protector 7 abuts against the adjacent frame 1 .

[0044] In summary, by embedding the upper protrusion 33 between the upper and lower structures 4 into the lower groove 43, the angle between adjacent frames 1 can be adjusted, achieving free angle adjustment. A single angle bracket can be used for multiple angles, reducing the number of production molds and logistics requirements, thereby significantly reducing overall costs. The angle bracket's flexible adjustment, without the need for cutting the frame 1, allows for a variety of irregularly shaped photovoltaic modules and building structures. This provides greater compatibility and adaptability, especially when installing photovoltaic modules on complex building surfaces or special-shaped structures.
