Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and more specifically, it relates to a frame for a lightweight photovoltaic module. Background Technology

[0002] Balcony photovoltaics, as an emerging photovoltaic product, are constantly developing and upgrading. Their encapsulation generally adopts a glass-covered solution similar to ground-mounted power stations. These components require a special base frame for support during installation, and also require professional installers to drill holes, hoist them, and perform regular maintenance, resulting in high equipment and labor costs.

[0003] The support structure of balcony solar panels protrudes outwards from the balcony, affecting the building's aesthetics. Although some balcony solar panels use flexible materials to reduce weight and are mechanically installed by drilling holes at the edges and using bolts and straps, the overall rigidity is insufficient and the resistance is poor. In outdoor environments, long-term use carries the risk of bending and damage. The flimsy connections are also prone to tearing, causing the equipment to fall off and posing a safety hazard. In addition, moisture can enter through the holes in the flexible materials, corroding the photovoltaic cells and affecting power generation efficiency and electrical safety. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lightweight photovoltaic module frame to solve one or more of the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A frame for a lightweight photovoltaic module, including

[0007] Border body;

[0008] The upper cavity is opened horizontally at the upper end of the frame body, and extends through the left and right ends of the frame body, forming a closed-loop structure.

[0009] The lower cavity is horizontally opened at the lower end of the frame body, extending through the left and right ends of the frame body and through the bottom.

[0010] Furthermore, the upper cavity is formed by an integrally molded upper top edge, a front frame plate, a back frame plate, and an edge sealing plate.

[0011] Furthermore, the vertical cross-section of the top edge and the edge sealing plate are both upward-arched arc structures, the front plate of the frame is located at the upper front end of the frame body, and the back plate of the frame is located at the upper rear end of the frame body.

[0012] Furthermore, the curvature of the top edge is greater than the curvature of the edge banding.

[0013] Furthermore, the lower cavity is formed by an integrally molded front edge baffle, a sealing edge plate, and a rear edge baffle, wherein the front edge baffle and the rear edge baffle are not connected.

[0014] Furthermore, the front edge baffle is located at the lower front end of the frame body, and the rear edge baffle is located at the lower rear end of the frame body. The downward length of the front edge baffle is less than the downward length of the rear edge baffle.

[0015] Furthermore, the ends of both the leading edge baffle and the trailing edge baffle have inwardly bent arc-shaped hooks.

[0016] Furthermore, the top of the frame body is provided with at least two waist-shaped holes that penetrate the upper cavity.

[0017] In summary, this utility model has the following beneficial effects: The two waist-shaped holes at the top, combined with the semi-open lower cavity, allow for the connection of railings with most diameters and distribution densities. Efficient and convenient installation is achieved through the use of strips or bayonets, reducing installation difficulty. Balcony photovoltaic modules can be installed in various scenarios such as walls, balcony railings, protective nets, protective windows, and roof railings. The smooth treatment of the frame body, such as the arc design and hook structure, effectively releases stress, enhances safety and stability, and reduces the impact on the photovoltaic panels.

[0022] Example:

[0023] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0024] A frame for a lightweight photovoltaic module, such as Figure 2As shown, the main body of the frame is an integrated aluminum alloy frame that attaches to the edge of the photovoltaic module B. Two symmetrical waist-shaped holes 9 are located at the top of the frame body for subsequent connection to external objects, completing the fixed installation. Figure 1 As shown, the frame body has a horizontally and horizontally connected upper cavity 2 and lower cavity 6. The upper cavity 2 is located at the upper end of the frame body, and the lower cavity 6 is located at the lower end. The vertical cross-section of the upper cavity 2 is a closed loop structure, while the vertical cross-section of the lower cavity 6 is a semi-open structure with a through bottom. A waist-shaped hole 9 vertically penetrates the top of the upper cavity 2. The frame body is integrally formed from a frame back plate 3, a frame front plate 4, an edge sealing plate 5, a front edge baffle 7, and a rear edge baffle 8. The vertical cross-sections of the upper top edge 1 and the edge sealing plate 5 are both upward-arched arc structures, with the curvature of the upper top edge 1 being greater than that of the edge sealing plate 5. The upper top edge 1, the frame front plate 4, the frame back plate 3, and the edge sealing plate 5 enclose the upper cavity 2, and the four are connected sequentially. The front edge baffle 7, the edge sealing plate 5, and the rear edge baffle 8 form the lower cavity 6. The front edge baffle 7 and the rear edge baffle 8 are not connected, meaning the upper cavity 2 is completely closed, while the bottom of the lower cavity 6 is open. The front frame plate 4 is located at the upper front side of the frame body, the back frame plate 3 is located at the upper rear side of the frame body, the front edge baffle 7 is located at the lower front side of the frame body, and the rear edge baffle 8 is located at the lower rear side of the frame body. The downward length of the front edge baffle 7 is less than the downward length of the rear edge baffle 8, meaning the front end notch of the frame body is larger than the rear end notch. The ends of both the front edge baffle 7 and the rear edge baffle 8 have arc-shaped hooks that bend downwards into the cavity 6.

[0025] The arc structure of the upper edge 1 reduces stress during bending. The upper cavity 2 and lower cavity 6 provide support for the entire frame body. The lower cavity 6 also serves to seal the photovoltaic module B. The front edge baffle 7 and rear edge baffle 8 work together to block the encapsulating adhesive, preventing excessive overflow. The waist-shaped hole 9 is used to fix the strip or clips. Figure 3 As shown, the frame body is mainly used in installation scenarios without dedicated brackets. It has installation corner brackets A at the four corners, which are specially designed for the edge encapsulation of lightweight flexible components. After connecting the photovoltaic module B, it can be installed on objects such as balcony railings, protective nets, and protective windows by passing through the waist-shaped hole 9 through the strip or the bayonet. The operation is simple and has few limitations.

[0026] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
