Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a connection structure between the frame and corner bracket of a photovoltaic module. Background Technology

[0002] Photovoltaic power generation, as a clean energy source, is highly regarded globally and has received strong support and development. Photovoltaic modules, as an indispensable core component of photovoltaic power generation, have undeniable value. Currently, photovoltaic modules are divided into two main categories: framed and frameless. Framed photovoltaic modules, due to their higher safety and reliability in applications, have gained wider market recognition and adoption.

[0003] Most existing photovoltaic module frames and corner brackets are reinforced by riveting. Due to the high cost of aluminum, corner brackets are generally designed with long and short sides, connecting to the long and short frames respectively. However, the difference between the long and short sides of the corner brackets is not significant, which can easily lead to installation errors. Frame parts are usually closed mounting cavities, and the connection is only reinforced by riveting, which has limited restraint and increases the cost of frame parts and stamping production processes. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic module frame and corner bracket connection structure to solve the above problems. It adopts multiple differentiated error-proof designs to prevent installation errors, symmetrical rivet points to meet load requirements, and through ribs to reduce the stamping production process of frame parts and the use of aluminum materials, thereby reducing costs.

[0005] Technical Solution: This utility model provides a photovoltaic module frame and corner bracket connection structure, including: a short frame, corner bracket components, and a long frame. The short frame has a first vertical plate and a second vertical plate on both sides, and a third vertical plate inside. The corner bracket component includes a long frame arm and a short frame arm, which are arranged perpendicularly to each other. The long frame arm and the short frame arm have differentiated error-proof designs, and their inner surfaces are provided with serrations. The long frame has a first baffle and a second baffle on both sides, and a third baffle inside. The short frame and long frame adopt an open design, which facilitates production, saves aluminum material, and reduces costs.

[0006] Furthermore, in the aforementioned photovoltaic module frame and corner bracket connection structure, the second and third vertical plates form a short frame mounting cavity, and the second and third baffles form a long frame mounting cavity, respectively connecting the short frame arm and the long frame arm. A stamped boss is provided on the inner side of the second baffle, which is formed by stamping into the end of the long frame arm after installation. This ensures that the corner bracket is constrained by forces in both directions within the long frame mounting cavity, making it secure and reliable.

[0007] Furthermore, in the aforementioned photovoltaic module frame and corner bracket connection structure, the second and third vertical plates are provided with symmetrically arranged folded edges. After the short frame arm is inserted and connected, the folded edges are stamped inwards towards the short frame arm, symmetrically stamping four rivet points. The rivet points interfere with the toothed grooves on the short frame arm. This pre-assembly followed by stamping approach facilitates and speeds up stamping production, ensures controllable production quality, and maintains symmetrical dimensions, significantly meeting the load requirements of solar photovoltaic modules.

[0008] Furthermore, in the aforementioned photovoltaic module frame and corner bracket connection structure, both the long and short frame arms adopt a hollow design, and the ends are provided with a constricted neck design for easy nesting. This allows the corner bracket to be easily connected to the short and long frames.

[0009] Furthermore, in the aforementioned photovoltaic module frame and corner bracket connection structure, several reinforcing plates are evenly arranged inside the long frame arm and short frame arm, which improves the structural strength and load-bearing capacity of the corner bracket.

[0010] Furthermore, in the aforementioned photovoltaic module frame and corner bracket connection structure, the foolproof design includes groove structures located at the ends of the long frame arms, the right-angle interior corners of the corner brackets, and the outer sides of the short frame arm connecting reinforcement plates. These multiple differentiated foolproof designs prevent incorrect installation during assembly.

[0011] Furthermore, in the aforementioned photovoltaic module frame and corner code connection structure, the third baffle is provided with a folded edge, and a through rib is provided on the folded edge. The through rib is interference-fitted with the toothed pattern on the long frame arm, which reduces the stamping production process of the long frame, improves the constraint force, and makes it more robust and reliable.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: The photovoltaic module frame and corner bracket connection structure of this utility model adopts an open design for the connection cavity of the frame and corner bracket, which facilitates production and processing, saves aluminum material, and reduces costs. The corner bracket is equipped with multiple differentiated anti-mistake designs to prevent installation errors during assembly. The corner bracket and the short frame are installed first and then the rivet points are stamped. The rivet points and the tooth pattern interfere with each other. The rivet points are symmetrically set, making the stamping production convenient and fast and the production quality controllable. The third baffle is provided with a through rib that forms an interference fit with the tooth pattern, reducing the stamping production process of the long frame. The inner side of the second baffle is stamped to form a stamping boss at the end of the long frame arm, so that the corner bracket is constrained by forces in both directions in the long frame mounting cavity, making it firm and reliable.

The long frame 3 has a first baffle 31 and a second baffle 32 on both sides, and a third baffle 33 inside. The short frame 1 and the long frame 3 adopt an open design, which facilitates production, saves aluminum materials, and reduces costs.

[0020] like Figure 3 The diagram illustrates a photovoltaic module frame and corner bracket connection structure. The second vertical plate 12 and the third vertical plate 13 form a short frame mounting cavity 14, and the second baffle 32 and the third baffle 33 form a long frame mounting cavity 34, connecting the short frame arm 22 and the long frame arm 21 respectively. A stamped boss 311 is provided on the inner side of the second baffle 32. The stamped boss 311 is formed by stamping into the end position of the long frame arm 21 after it is installed. This ensures that the corner bracket 2 is constrained by forces in both directions within the long frame mounting cavity 34, making it secure and reliable.

[0021] like Figure 2 The diagram illustrates a photovoltaic module frame and corner bracket connection structure. The second vertical plate 12 and the third vertical plate 13 have symmetrically arranged folded edges. After the short frame arm 22 is inserted and connected, four rivet points 121 are symmetrically stamped onto the short frame arm 22 using a stamping method. These rivet points engage with the teeth 24 on the short frame arm 22. This pre-assembly followed by stamping approach facilitates convenient and rapid stamping production, ensures controllable production quality, and maintains symmetrical dimensions, significantly meeting the load requirements of solar photovoltaic modules.

This allows the corner bracket 3 to be easily connected to the short frame 1 and the long frame 3.

[0024] In this embodiment, several reinforcing plates 25 are evenly arranged inside the long frame arm 21 and the short frame arm 22, which improves the structural strength of the corner bracket 2 and increases its load-bearing capacity.

[0025] In this embodiment, the foolproof design 23 includes groove structures provided on the outer side of the long frame arm 21 end position, the right-angle interior corner position of the corner bracket 2, and the position where the short frame arm 22 connects to the reinforcing plate 25. Multiple differentiated foolproof designs 23 prevent incorrect installation during assembly.

[0026] like Figure 1 , 3 The diagram shows a photovoltaic module frame and corner bracket connection structure. The third baffle 33 is provided with a folded edge, and the folded edge is provided with a through rib 331. The through rib 331 is interference-fitted with the tooth pattern 24 on the long frame arm 21, which reduces the stamping production process of the long frame 3, improves the constraint force, and makes it more robust and reliable.
