Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to photovoltaic module frames. Background Technology

[0002] In the field of photovoltaic modules, steel frames provide support and protection for photovoltaic panels, and must withstand wind and snow loads as well as external forces during installation and transportation. However, existing steel frames have significant shortcomings:

[0003] Poor structural performance: Traditional cross-sectional structures are simple and prone to large deformations under load. For example, in strong wind conditions, the deflection often exceeds industry standards, affecting the stability and lifespan of photovoltaic modules. In addition, they have weak torsional resistance and are easily damaged when subjected to torsional forces.

[0004] Inappropriate use of materials: In order to ensure strength, the wall thickness is increased excessively or redundant structures are adopted, resulting in a large frame weight. This not only increases material costs, but also increases the difficulty of transporting and installing components, and increases the load on the photovoltaic support.

[0005] Poor molding and compatibility: The unreasonable design of the corners and stiffeners of the cross section makes it easy to generate stress concentration during molding processes such as rolling and stamping, resulting in defects such as cracking and wrinkles, which reduces the production qualification rate. At the same time, the poor compatibility with the connection structure of photovoltaic panels and brackets makes assembly inconvenient and affects sealing and stability.

[0006] Therefore, developing new steel frame cross-sections that combine excellent mechanical properties, lightweight design, and advantages in forming and assembly has become an urgent need for optimizing the structure of photovoltaic modules. Utility Model Content

[0007] To address the aforementioned issues, this invention proposes a photovoltaic module frame that possesses excellent mechanical properties and is simple to manufacture and assemble.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A photovoltaic module frame includes a main structure with a certain extension length and a generally rectangular cross-section, and the top of the main structure has a clamping assembly structure;

[0010] The top surface of the main structure facing the clamping assembly structure has a first reinforcing structure that is recessed into the interior of the main structure.

[0011] The inner surface of the main structure has an inwardly recessed second reinforcing structure.

[0012] Preferably, the first reinforcing structure is C-shaped.

[0013] Preferably, the second reinforcing structure is a trapezoidal structure.

[0014] Preferably, the main structure is a frame structure made of stamped and bent metal sheet. The top surface of the main structure is the first surface layer. One side of the first surface layer is bent downward to form the second surface layer. The lower end of the second surface layer is bent outward to form the third surface layer. The side of the third surface layer away from the second surface layer is bent upward to form the fourth surface layer.

[0015] Preferably, the clamping assembly structure is a structure formed by stamping and bending the first surface layer away from the second surface layer.

[0016] Preferably, the structure includes an upper extension formed by bending upward from the end of the first surface layer, and the upper extension is bent inward away from the first surface layer to form an inner extension.

[0017] The main body of the inner extension is parallel to the first surface layer.

[0018] Preferably, the end of the fourth layer away from the third layer is bent inward to form a bent support portion, and the top surface of the bent support portion is attached to the bottom surface of the first layer.

[0019] Preferably, the end of the bent support portion is adjacent to or abuts against the first reinforcing structure.

[0020] Preferably, the side of the first surface layer adjacent to the second surface layer is an inclined section.

[0021] Preferably, in the main structure and the clamping assembly structure, the corners of each surface section are R2-R3 rounded chamfers.

[0022] The beneficial effects of using this utility model are:

[0023] This novel photovoltaic module frame achieves significant advantages through the synergistic effect of the first reinforcing structure, the second reinforcing structure, and the rectangular main structure's bending and torsional resistance structure: in terms of mechanical performance, it greatly improves bending and torsional resistance, ensuring the stability and lifespan of the module structure; it provides an innovative solution for upgrading photovoltaic module structures and has high practical value and promotion potential.

[0024] In terms of production, it is formed by bending metal sheets, which makes production more convenient and eliminates the need for heat treatment. In terms of assembly, the use of inclined sections creates a flared inlet structure, facilitating assembly. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0029] like Figure 1 As shown, the photovoltaic module frame proposed in this embodiment includes a main structure with a certain extension length and a generally rectangular cross-section. The top of the main structure has a clamping assembly structure; the surface of the top surface of the main structure facing the clamping assembly structure has a first reinforcing structure 11 that is recessed into the interior of the main structure; and the inner side of the main structure has a second reinforcing structure 21 that is recessed inward.

[0030] Specifically, the first reinforcing structure 11 is C-shaped. The second reinforcing structure 21 is a trapezoidal structure.

[0031] The main structure is a frame structure made of metal sheet stamping and bending. The top surface of the main structure is the first surface layer 1. One side of the first surface layer 1 is bent downward to form the second surface layer 2. The lower end of the second surface layer 2 is bent outward to form the third surface layer 3. The side of the third surface layer 3 away from the second surface layer 2 is bent upward to form the fourth surface layer 4.

[0032] The clamping assembly structure is a structure formed by stamping and bending the first surface layer 1 away from the second surface layer 2. The structure includes an upper extension 6 formed by bending the end of the first surface layer 1 upwards, and an inner extension 7 formed by bending the upper extension 6 away from the first surface layer 1 inwards; the main body of the inner extension 7 is parallel to the first surface layer 1.

[0033] The end of the fourth layer 4, which is away from the third layer 3, is bent inward to form a bent support part 5, and the top surface of the bent support part 5 is attached to the bottom surface of the first layer 1.

[0034] The end of the bent support 5 is near or abuts the first reinforcing structure 11. The side of the first surface layer 1 adjacent to the second surface layer 2 is an inclined section 12.

[0035] Specifically, the photovoltaic module frame features a one-piece molded closed cavity structure, cleverly integrating multiple functional areas to structurally ensure performance.

[0036] In the first surface layer 1, the first reinforcing structure 11 is an arc-shaped protrusion, laterally distributed on the first surface layer 1 (on the side adjacent to the photovoltaic panel mounting surface). Its function is to enhance the local rigidity of the first surface layer 1, resist the pressure on the frame during photovoltaic panel installation and loading, and prevent the first surface layer 1 from being concave and deformed. At the same time, the inclined section 12 provides a certain positioning guide for panel installation.

[0037] The second reinforcing structure 21 is a trapezoidal reinforcing rib: it is set on the second surface layer 2 of the cross section. The trapezoidal structure can effectively disperse the longitudinal load borne by the second surface layer 2, transfer the force to the entire cross section, improve the bending and shear resistance of the frame, and especially enhance the load-bearing performance in the vertical direction.

[0038] The rectangular anti-bending and anti-torsion structure in the main structure is composed of the third surface layer 3, the fourth surface layer 4, and the bending support part 5. The rectangular cavity utilizes its own geometric characteristics to significantly improve the overall bending and torsional resistance of the frame, providing a stable support frame for the photovoltaic module and resisting deformation under complex working conditions.

[0039] In terms of multi-ribbed synergistic reinforcement, the first reinforcing structure 11, the second reinforcing structure 21, and the main structure are not independent but rather work together. The first surface layer 1 bears the panel load and transmits it to the second surface layer 2 and the third surface layer 3, and even to the bending support 5; the second surface layer 2 disperses the longitudinal force to the rectangular cavity; the rectangular cavity, as the main load-bearing structure, integrates forces in all directions, making the overall frame more uniformly stressed, fully utilizing the mechanical properties of the material, and achieving high load-bearing capacity with a small cross-sectional size.

[0040] In terms of the design to adapt to the forming process, each corner of the cross section adopts a rounded transition of R2-R3mm (traditionally, it is mostly right angle or small rounded corner) to reduce stress concentration during roll forming and stamping; the connection between the stiffener and the wall adopts a gradual thickness design (transition section length 3-5mm) to avoid forming cracks, improve the production qualification rate, and enhance the fatigue life of the structure.

[0041] In terms of connection and adaptation optimization, adapter slots and boss structures are set at the connection points between the cross section and the photovoltaic panel and bracket. The width and depth of the slots match the commonly used photovoltaic panel frame seals (slot width 5-6mm, depth 2-3mm), and the bosses are used to precisely fit with the bracket mounting holes. No additional complex connectors are required, simplifying assembly and ensuring connection sealing and stability.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
