Corner bracket for photovoltaic modules

Abstract

This utility model discloses a corner bracket for photovoltaic modules, comprising two corner-connected connecting arms. Each connecting arm includes a connected sidewall and a bottom wall. The sidewalls of the two connecting arms are bent and connected, and the bottom walls of the two connecting arms are snapped together in a rhomboid shape. This rhomboid snap-fit ​​between the two bottom walls allows for effective connection and interlocking, preventing expansion and deformation under pressure, thus providing an elastic self-locking effect and improving the compressive strength of the corner bracket itself. The addition of convex reinforcing ribs strengthens the sidewalls and bottom wall, preventing unilateral stress from widening and twisting, significantly improving bending and torsional resistance, and further enhancing the compressive strength of the corner bracket. The inclusion of a hook-shaped toothed structure not only guides during installation, improving installation efficiency, but also strengthens the connection between the corner bracket and the frame, effectively preventing the corner bracket from loosening or shifting.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to corner brackets for photovoltaic modules. Background Technology

[0002] With the widespread application of solar photovoltaic power generation technology, the demand for the installation and fixing of photovoltaic modules is increasing. Corner brackets, as a key connection and fixing component, are widely used in the corner connections of photovoltaic module frames. Their structural strength, ease of installation, and connection reliability directly affect the stability and lifespan of the entire photovoltaic power generation system.

[0003] Existing corner brackets suffer from the following shortcomings: First, their connection strength is limited, especially under long-term dynamic loads such as wind and snow, making them prone to deformation or loosening, affecting structural stability. Second, the corner brackets rely on bolts for fastening to the photovoltaic module frame, which lack sufficient clamping force and tensile strength, posing a risk of loosening. Third, the lack of an effective positioning and guiding design makes alignment difficult during installation, resulting in low installation efficiency. Therefore, it is necessary to improve the existing corner bracket structure to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to disclose a corner bracket for photovoltaic modules, which enables effective connection and interlocking of the two bottom walls through a diamond-shaped interlocking mechanism. This prevents the two bottom walls from expanding and deforming under pressure, providing an elastic self-locking effect and improving the compressive strength of the corner bracket itself. The addition of convex reinforcing ribs strengthens the side and bottom walls, preventing unilateral stress from widening and twisting, significantly improving bending and torsional resistance, and further enhancing the compressive strength of the corner bracket. The use of a hook-shaped toothed structure not only guides the installation process, improving installation efficiency, but also strengthens the connection between the corner bracket and the frame, effectively preventing the corner bracket from loosening or shifting. The use of anchor holes and anchor bolts to fasten the bracket to the frame strips increases tensile strength, effectively preventing the corner bracket from loosening or shifting, further improving the connection strength between the corner bracket and the frame, and ultimately increasing installation efficiency.

[0005] To achieve the above objectives, this utility model provides a corner bracket for photovoltaic modules, comprising two corner-connected connecting arms. Each connecting arm includes a connected side wall and a bottom wall. The side walls of the two connecting arms are bent and connected, and the bottom walls of the two connecting arms are snapped together in a rhomboid shape.

[0006] In some embodiments, the outer edge of the sidewall is provided with an inwardly folded extension wall, and the free end of the extension wall is provided with a barbed tooth structure.

[0007] In some embodiments, the connecting arm is provided with a convex reinforcing rib, the two ends of which extend to the side wall and the bottom wall, respectively.

[0008] In some embodiments, the sidewall is provided with multiple anchor holes.

[0009] In some embodiments, the bottom wall is provided with multiple anchor bolts.

[0010] In some embodiments, both the sidewalls and the bottom wall are provided with inwardly inclined guide plates.

[0011] In some implementations, the two connecting arms are arranged vertically.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: The two bottom walls are connected by a diamond-shaped interlocking mechanism, enabling effective connection and interlocking to prevent expansion and deformation under pressure, thus providing elastic self-locking and improving the compressive strength of the corner bracket itself. The addition of convex reinforcing ribs strengthens the side and bottom walls, preventing unilateral stress from widening and twisting, significantly improving bending and torsional resistance, and further enhancing the compressive strength of the corner bracket itself. The barbed toothed structure not only guides the installation process, improving efficiency, but also strengthens the connection between the corner bracket and the frame, effectively preventing loosening and displacement. The use of anchor holes and anchor bolts to fasten the corner bracket to the frame strips increases tensile strength, effectively preventing loosening and displacement, further strengthening the connection between the corner bracket and the frame, and improving installation efficiency.

[0017] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0018] like Figure 1-4 The photovoltaic module corner bracket shown includes two corner connecting arms 1, which are arranged vertically. One connecting arm 1 is connected to the long frame strip, and the other connecting arm 1 is connected to the short frame strip.

[0019] The connecting arm 1 includes a side wall 2 and a bottom wall 4 connected to each other. The side wall 2 and the bottom wall 4 are arranged vertically and are an integral structure. The side walls 2 of the two connecting arms 1 are bent and connected and are an integral structure.

[0020] The bottom walls 4 of the two connecting arms 1 are engaged. Specifically, one bottom wall 4 has a locking block 43, and the other bottom wall 4 has a locking groove 42. The locking block 43 is held in the locking groove 42. The locking block 43 and the locking groove 42 are rhomboid in shape, which allows the two bottom walls 4 to be effectively connected and interlocked, preventing the two bottom walls 4 from expanding and deforming under pressure, thus playing an elastic self-locking role and improving the compressive strength of the corner bracket itself.

[0021] The connecting arm 1 is provided with a convex reinforcing rib 5, which extends to the side wall 2 and the bottom wall 4 at both ends. It can uniformly transmit pressure, reduce local stress concentration, increase the cross-sectional moment of inertia of the material, strengthen the strength of the side wall 2 and the bottom wall 4, prevent the single-sided force angle from expanding and twisting deformation, significantly improve the bending and torsional resistance, and improve the compressive strength of the corner bracket itself.

[0022] The outer edge of the side wall 2 is provided with an inwardly folded extension wall 3, and the side wall 2 and the extension wall 3 are an integral structure. The free end of the extension wall 3 is provided with a barbed toothed structure 31. The extension wall 3 and the barbed toothed structure 31 are confined within the corner bracket slot 7 on the frame strip. On the one hand, it plays a guiding role during the installation of the corner bracket, improving the installation efficiency; on the other hand, the barbed toothed structure 31 abuts against the groove 81, with multiple stress points and strong tensile strength, improving the connection strength between the corner bracket and the frame, and effectively preventing the corner bracket from loosening or shifting. In actual use, under the influence of pressure, the teardrop-shaped support beam 8 on the frame strip will shift towards the barbed toothed structure 31. The groove 81 on the teardrop-shaped support beam 8 can always maintain a tight press with the barbed toothed structure 31, resulting in excellent connection strength.

[0023] The side wall 2 is provided with two staggered anchor holes 21 to be fastened to the anchors on the frame strip; the bottom wall 4 is provided with two staggered anchors 41 to be fastened to the anchor holes on the frame strip. At the same time, the staggered installation points can better distribute the force evenly, have strong tensile strength, effectively prevent the corner bracket from loosening and shifting, improve the connection strength between the corner bracket and the frame, and improve the installation efficiency.

[0024] Both the side wall 2 and the bottom wall 4 are provided with inwardly inclined guide pieces 6, which play a moving guiding role during the installation of the corner brackets and improve the installation efficiency.

[0025] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
