Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy frames, in particular to an aluminum alloy frame with an anodized film having high thermal cracking resistance. Background Art

[0002] Anodizing is a process of forming an oxide film on the surface of aluminum and its alloys by electrochemical methods. It can improve the performance of the metal surface. The existing aluminum alloy will be enhanced in terms of heat resistance, corrosion resistance and mechanical properties while improving the strength of the alloy through the adhesion of the anti-thermal cracking anodized film.

[0003] When using aluminum alloy frames on solar cell packaging, since the aluminum alloy frames are mostly used outdoors, a heat-cracking-resistant anodized film is often formed on the surface of the aluminum alloy frames to increase the service life of the aluminum alloy frames and protect the solar cells. However, although the film layer can improve the strength of the aluminum alloy, if the aluminum alloy is damaged and cracked by impact, the heat-cracking-resistant anodized film will also rupture. Once the film body is cracked and loses its integrity, the improvement of the overall strength of the aluminum alloy by the film body will also be destroyed, so that its protection of the solar cell is also reduced, thereby affecting the service life of the solar energy.

[0004] Therefore, it is necessary to design an aluminum alloy frame with a high thermal cracking resistance anodized film to solve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] See also Figure 1-4The utility model provides an aluminum alloy frame with a high thermal cracking resistance anodized film, comprising two first frames 1 and two second frames 2 threadedly connected to the two first frames 1, the outer surfaces of the two first frames 1 and the two second frames 2 are formed with a high thermal cracking resistance anodized film body 9, the two first frames 1 and the two second frames 2 form a square frame, the tops and bottoms of the two first frames 1 are provided with inlays 11, the two ends of the two second frames 2 are fixedly connected with protrusions 12, the four protrusions 12 at the two ends of the two second frames 2 are respectively threadedly connected to the inside of the two inlays 11 at the top and bottom of the first frames 1, the two right angles of the two first frames 1 are filled with filling blocks 6, the tops and bottom right angles of the two first frames 1 are fixedly connected with right-angle blocks 7, and the four right-angle blocks 7 are respectively threadedly connected to the two ends of the two second frames 2, when the frame is passed through When the two first frames 1 and the two second frames 2 are assembled, the high heat cracking resistance anodized film body 9 formed on the outer surfaces of the two first frames 1 and the two second frames 2 is used to improve the use strength of the frame after the overall assembly, and the battery is protected after being wrapped on the surface of the solar cell. By filling the two right angles of the two first frames 1 with filling blocks 6 and utilizing the elasticity of the two four filling blocks 6, the two more fragile right angles of the two first frames 1 can be elastically protected by the four filling blocks 6 respectively, thereby reducing the degree of damage to the two first frames 1 when impacted, thereby avoiding the cracking of the aluminum alloy right angles to a certain extent. By setting the four right-angle blocks 7, the strength of the four corners of the frame is further improved, thereby avoiding the problem of reduced overall strength of the frame when the integrity of the high heat cracking resistance anodized film body 9 is reduced, and avoiding the problem of reduced protection of the frame to the solar cell.

[0023] Furthermore, in order for the solar cell to be well installed inside the frame when the frame is assembled, the inner side of the first frame 1 is fixedly connected with a second rubber block 8, and the outer surface of the two second frames 2 is fixedly connected with a first rubber block 3, and the two ends of the two second rubber blocks 8 are respectively fitted with one end of the four right-angle blocks 7, and the two ends of the two first rubber blocks 3 are respectively fitted with the other ends of the corresponding four right-angle blocks 7, so that the two second rubber blocks 8 and the two first rubber blocks 3 can respectively play a certain supporting role on the two ends of the four right-angle blocks 7.

[0024] Furthermore, although the two highly heat-cracking-resistant anodized film bodies 9 are heat-resistant on the outer surface of the frame, the solar cells are installed inside the frame and need to dissipate heat to a certain extent. Diamond-shaped openings 10 are provided inside the two second rubber blocks 8, and multiple ventilation and drainage holes 5 are provided on the outer surface of one side of the top and bottom ends of the two first frames 1. Through the arrangement of the diamond-shaped openings 10 and the arrangement of the multiple ventilation and drainage holes 5, the closed parts inside the frame have a certain degree of heat dissipation. When the frame is in use, according to the characteristics of the solar cell, the frame needs to be tilted and placed. When water droplets appear inside the frame, the diamond shape makes it convenient to gather the water droplets into a water source and send them to the multiple ventilation and drainage holes 5 for discharge.

[0025] The water droplets mentioned in the above description are gathered through multiple ventilation and drainage holes 5 that are obliquely opened on one side of the outer surface of the two first frames 1, and the hole height of the multiple ventilation and drainage holes 5 on the top of the diamond-shaped opening 10 on the side of the first frame 1 is higher than the hole height on the side of the second rubber block 8, and the hole height of the multiple ventilation and drainage holes 5 on the bottom of the diamond-shaped opening 10 on the side of the first frame 1 is lower than the hole height on the side of the second rubber block 8. The diamond shape and the multiple ventilation and drainage holes 5 can better cooperate with the discharge of water droplets after gathering.

[0026] In order to better protect the four corners of the frame, the filling block 6 is L-shaped and is a rubber body, so that the strength of the four corners of the frame is improved by the elasticity of the material of the filling block 6 and the position of the filling block 6 at the four corners of the frame.

[0027] In order to enable the solar cell to be more stably installed inside the frame, the thickness of the two first rubber blocks 3 and the two second rubber blocks 8 are matched with the thickness of the two ends of the right-angle block 7 .

[0028] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0029] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0030] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
