Description

Technical Field

[0001] This utility model relates to the field of solar cell frame assembly technology, and in particular to an elastic support type corner bracket connector for solar cell frames. Background Technology

[0002] In solar photovoltaic systems, solar panels are fixed and supported by frame brackets, which are typically connected using corner brackets. Traditional corner brackets mostly use bolts or screws for fastening, resulting in low installation efficiency, reliance on installation tools, and susceptibility to loosening due to vibration. Some corner brackets use interference fits or snap-fit ​​structures, but in practical applications, they often suffer from insufficient preload, poor adaptability, or inability to effectively compensate for frame dimensional tolerances, leading to poor connection stability and potential frame deformation or connection failure over long-term use. Furthermore, existing corner bracket structures are complex and have high production costs, making it difficult to meet the requirements for fast, tool-free installation while ensuring connection strength. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problems that the existing corner brackets adopt interference fit or snap-fit ​​structure, but often have insufficient preload, poor adaptability or inability to effectively compensate for the frame size tolerance in actual application, resulting in poor connection stability and the possibility of frame deformation or connection failure in long-term use, this utility model provides an elastic support type corner bracket connector for solar frame.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an elastic support type corner bracket connector for solar frame, including a main connecting seat, and two oppositely arranged connecting arms on the end of the main connecting seat. The connecting arms include an elastic connecting section and a first fixed section. The first end of the elastic connecting section is fixedly connected to the end of the main connecting seat, and the tail end of the elastic connecting section is fixedly connected to the first fixed section. The elastic connecting section protrudes in the direction of the connecting arm on the other side and contacts the elastic connecting section of the connecting arm on the other side. Through the symmetrically arranged elastic connecting sections, elastic deformation is generated during installation and a continuous pre-tightening force is provided, which effectively adapts to the width tolerance of the solar frame and avoids loosening of the connection. In the initial state, the spacing between the first fixed segments of the connecting arm is greater than the width L of the solar panel frame.

[0005] To address the issues of corner brackets easily detaching from the frame and having poor vibration resistance, the system further includes a first fixing tooth on the side of the first fixing section near the solar frame, with the first fixing tooth inclined toward the end of the main body connector to which it is connected.

[0006] To address the problem of insufficient clamping force and easy fatigue failure when relying solely on a single-segment connecting arm, the connecting arm is further improved by including a second fixed segment, wherein the first end of the second fixed segment is fixedly connected to the end of the main body connecting seat, and the last end of the second fixed segment is fixedly connected to the first end of the elastic connecting segment.

[0007] To address the issue of the lack of multi-point locking between the corner bracket and the frame, which makes it prone to wobbling, the system further includes a second fixing tooth on the side of the second fixing section near the solar frame, with the second fixing tooth inclined toward the end of the main body connector to which it is connected.

[0008] To address the issues of difficult alignment and low installation efficiency during frame insertion, the system further includes an inlet section at the tail end of the first fixed segment that slopes toward the center of the two connecting arms.

[0009] To address the issue of uneven force distribution that may result from relying solely on the connecting arm for clamping, an auxiliary elastic support section is further included between the first fixed sections of the two connecting arms.

[0010] The beneficial effects of this utility model are: the elastic support type corner bracket connector for solar panel frames provided by this utility model, through symmetrically arranged elastic connecting sections, generates elastic deformation during installation and provides continuous pre-tightening force, effectively adapting to the width tolerance of the solar panel frame and avoiding loosening of the connection.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1This is a structural schematic diagram of the present invention. A flexible support type corner bracket connector for a solar panel frame includes a main connecting seat 1. The end of the main connecting seat 1 has two oppositely arranged connecting arms 2. The connecting arm 2 includes an elastic connecting section 21 and a first fixing section 22. The first end of the elastic connecting section 21 is fixedly connected to the end of the main connecting seat 1, and the tail end of the elastic connecting section 21 is fixedly connected to the first fixing section 22. The elastic connecting section 21 protrudes in the direction of the connecting arm 2 on the other side and contacts the elastic connecting section 21 of the connecting arm 2 on the other side. Through the symmetrically arranged elastic connecting sections 21, elastic deformation is generated during installation and a continuous pre-tightening force is provided, which effectively adapts to the width tolerance of the solar panel frame and avoids loosening of the connection. In the initial state, the spacing between the first fixed segments 22 of the connecting arm 2 is greater than the width L of the solar frame.

[0016] like Figure 1 , 2 As shown, the main connecting seat 1 and the connecting arm 2 adopt an integrated structure. The integrated structure design reduces the number of parts, lowers production costs, and ensures connection strength.

[0017] like Figure 1 , 2 As shown, the first fixed section 22 has a first fixed tooth 221 on the side near the solar frame. The first fixed tooth 221 is inclined toward the end of the main body connecting seat 1 to which it is connected. The first fixed tooth 221 forms a one-way self-locking to prevent the corner bracket from coming out in the opposite direction and to enhance the vibration resistance.

[0018] like Figure 1 , 2 As shown, the connecting arm 2 includes a second fixed section 23. The first end of the second fixed section 23 is fixedly connected to the end of the main body connecting seat 1, and the tail end of the second fixed section 23 is fixedly connected to the first end of the elastic connecting section 21. The second fixed section 23 increases the support points and improves the structural strength and durability.

[0019] like Figure 1 , 2 As shown, the second fixing segment 23 has a second fixing tooth 231 on the side near the solar frame. The second fixing tooth 231 is inclined toward the end of the main body connecting seat 1 to which it is connected. The second fixing tooth 231 further increases the mechanical locking point and improves the connection reliability.

[0020] like Figure 1 , 2 As shown, the tail end of the first fixed section 22 has an inlet section 24 that is inclined toward the center of the two connecting arms 2. The inlet section 24 guides the frame to be quickly aligned and inserted, simplifying the installation operation. The inlet section 24 guides the frame to be inserted smoothly, and the installation can be completed without tools, which significantly improves the construction efficiency.

[0021] like Figure 1 , 2 As shown, there is an auxiliary elastic support section 3 between the first fixed sections 22 of the two connecting arms 2. The auxiliary elastic support section 3 evenly distributes the clamping force to avoid deformation or local wear of the frame, further increasing the clamping force and stability of the frame and avoiding local stress concentration.

[0022] Installation process: Align the two connecting arms 2 of the corner bracket connector with the profile mounting cavity at the end of the solar panel frame; apply pressure along the length of the frame to push the corner bracket connector into the profile cavity of the frame; during insertion, the guide section 24 on the connecting arm 2 first contacts the profile cavity, guiding the connecting arm to enter smoothly; as the corner bracket goes deeper, the inner wall of the profile cavity will squeeze the two first fixing sections 22, forcing them to move towards each other, thereby causing the elastic connecting section 21 to elastically deform and contract towards the center, accumulating rebound force; when the corner bracket is installed in place, the elastic connecting section 21 releases the rebound force, pushing the first fixing section 22 to tightly press against the inner wall of the profile cavity; at the same time, the first fixing tooth 221 and the second fixing tooth 231 bite into the inner wall of the profile under the action of the rebound force, forming a one-way self-locking, effectively preventing the corner bracket from coming out; if an auxiliary elastic support section 3 is provided, it can also deform and provide additional support force, further enhancing the stability of the connection; after installation, the corner bracket connector is firmly fixed inside the frame profile by its elastic force and fixing teeth, forming a high-strength, high-reliability connection.

[0023] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
