[0002] With the rapid development of photovoltaic technology, solar panels are increasingly being used. Aluminum alloy frames and corner brackets are important components of solar panels. In the prior art, the corner brackets and aluminum alloy frames are mainly connected by external riveting and pressing.

[0003] For example, the utility model with existing patent application number: 201721204536.0 provides a solar cell assembly frame, wherein one side of the side frame is a front baffle, and the other side of the side frame is a glue overflow groove, and the glue overflow groove is composed of a front baffle and a rear baffle; the end of the side frame is provided with a guide angle code, the middle of the guide angle code is a hollow hole, and there are two connecting pieces in the middle of the hollow hole, the end of the guide angle code is chamfered, and the inner side of the guide angle code is a serrated surface; there are rivet points on the side frame inside the guide angle code.

[0004] However, with the rapid development of the offshore photovoltaic industry, aluminum alloy frames are no longer suitable for the high-salt, alkali and salt fog marine environment. The resulting polymer material frames cannot be riveted and pressed to ensure a tight connection between the frame and the photovoltaic material profile due to the small elastic modulus of the material. External filling is required to assist the connection, such as glue, which leads to high costs and difficult construction. In addition, the existing technology has high requirements on the matching dimensions of the corner code and the frame, resulting in a small application range of corner codes of specific sizes, high manufacturing costs and low economic benefits.

In addition, the prior art has high requirements on the matching dimensions of the angle code and the frame, resulting in a small application range of the angle code of a specific size, high manufacturing cost and low economic benefit.

[0021] The embodiment of the utility model provides a composite material profile connecting angle bracket with a cutting function.

[0022] See also Figure 1 , Figure 2 and Figure 3 , including a material profile 8, a mounting block 1 and a mounting block 2, a guide portion 6 is formed on one side of the top of the mounting block 1 and the mounting block 2, a cutting portion 5 is arranged on one side of the two guide portions 6, and an interference portion 4 is arranged on one side of the two cutting portions 5.

[0023] A U-shaped connecting structure 7 is fixedly connected between the mounting block 1 and the mounting block 2, and the mounting block 1, the mounting block 2 and the U-shaped connecting structure 7 constitute a U-shaped corner code piece, and the U-shaped corner code piece is used to install two material profiles 8 placed horizontally together. A right-angle corner structure 3 is fixedly connected between the mounting block 1 and the mounting block 2, and the mounting block 1, the mounting block 2 and the right-angle corner structure 3 constitute an L-shaped corner code piece, and the L-shaped corner code piece is used to install two material profiles 8 placed vertically to each other.

[0024] When the utility model is in use:

[0025] A U-shaped connecting structure 7 is fixedly installed between the mounting block 1 and the mounting block 2. The mounting block 1, the mounting block 2 and the U-shaped connecting structure 7 form a U-shaped corner piece. Figure 1As shown, when installing the material profile 8, the material profile 8 is inserted into the end of the U-shaped corner piece, and a guide portion 6 is provided on one side of the top of the mounting block 1 and the mounting block 2. The material profile 8 is first sleeved onto one end of the U-shaped corner piece where the guide portion 6 is provided, as shown in FIG. Figure 1 As shown, the guide part 6 is an inclined cantilever structure, at this time, the guide part 6 on the upper part of the mounting block 1 and the mounting block 2 is against the top of the inner cavity of the material profile 8, and the U-shaped connecting structure 7 is in contact with the bottom of the inner cavity of the material profile 8. When the U-shaped corner piece is installed, the U-shaped corner piece is pushed into the material profile 8 by external force. Since the height of the guide part 6 is greater than the height of the inner side of the frame and it is an inclined cantilever structure, the rigidity of the guide part 6 is relatively small; and in the forward direction of the movement of the guide part 6, the front end of the guide part 6 is small and the rear end is large, so the guide part 6 can provide sufficient positioning force during the movement without damaging the material profile 8. After the guide portion 6 of the U-shaped corner code piece completely enters the frame, continue to move the U-shaped corner code piece toward the inside of the material profile 8. When the height of the inside of the material profile 8 is less than the fitting tolerance, the cutting portion 5 formed on the top of the mounting block 1 and the mounting block 2 2 will cut the upper surface of the inner cavity of the material profile 8 to expand the height of the frame so that the dimensions of the U-shaped corner code piece and the material profile 8 meet the fitting requirements. The addition of the cutting portion 5 improves the applicability of angle codes of different specifications. After the cutting portion 5 completely enters the material profile 8, the U-shaped angle code piece continues to be pushed and moved toward the inside of the material profile 8. Since the height difference between the interference portion 4 opened at the bottom of the mounting block 1 and the mounting block 2 and the height of the material profile 8 is a reasonable interference amount, and the tooth tip of the interference portion 4 is opposite to the installation direction, the interference portion 4 can provide sufficient pulling force to ensure that the mounting block 1 and the mounting block 2 are tightly connected to the material profile 8 and do not fall off, thereby ensuring the stability of the use of the U-shaped angle code piece, and allowing the U-shaped angle code part to enter the inside of another material profile 8 set at one end of the material profile 8. The interference portion 4 is respectively set inside the two material profiles 8, and the two material profiles 8 are installed together, which can effectively solve the problem that the material profile 8 of the traditional polymer material photovoltaic panel and the stainless steel angle code cannot be tightly assembled. The installation effect is achieved by the interference portion 4 set inside the material profile 8, which has good resistance to environmental corrosion, and ensures that the material profile 8 of the polymer material photovoltaic panel and the angle code are installed compactly and stably.

[0026] In addition, after the right-angle corner structure 3 is fixed between the mounting block 1 and the mounting block 2, the mounting block 1, the mounting block 2 and the right-angle corner structure 3 form an L-shaped corner piece. Figure 3As shown, when installing two material profiles 8 through the L-shaped angle code piece, the two guide parts 6 respectively passing through the mounting block 1 and the mounting block 2 2 are sleeved onto the outside of the L-shaped angle code piece, so that the guide part 6 and the outside of the L-shaped angle code piece are against the inner sides of the material profile 8, and the material profile 8 is pushed toward the right-angle corner structure 3. In this process, the guide part 6, the cutting part 5, and the interference part 4 have the same functions as those in the U-shaped angle code piece. The two material profiles 8 are installed together through the L-shaped angle code piece. The setting of the cutting part 5 ensures that the size of the angle code and the material profile 8 are within a reasonable matching range, thereby improving the applicability of angle codes of different sizes.

[0027] In addition, according to experiments, it is found that when the interference fit of this embodiment is 0.3 mm, the pull-out force has reached the requirement of not falling off.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
