Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic module manufacturing field, concretely relates to prevent the frame of dust photovoltaic module. BACKGROUND

[0002] In the solar photovoltaic industry, the structure of the traditional photovoltaic module usually includes a rectangular laminated part composed of glass, cell pieces and high-temperature laminated materials such as adhesive film, and an external frame composed of four-edge assembled aluminum alloy profiles. The traditional aluminum alloy frame has a notch in the cross-sectional design, and the A face of the notch is 1-2 mm higher than the laminated part. This design causes the protrusion at the lower edge position of the photovoltaic module to easily accumulate a large amount of dust and sand. Due to the wind and rain in the natural environment, it is difficult to remove these dirt, which reduces the light irradiation of the photovoltaic module, thereby affecting the power generation, and in severe cases, it may even cause hot spot phenomenon, thereby affecting the reliability of the module.

[0003] In order to solve this problem, a new type of frame structure is designed in the prior art, which sets the long side and short side frames as no A face design, and uses the adhesive force of the sealant to ensure that the laminated part does not fall off. However, since the A face is removed, the laminated part completely relies on the sealant at the bottom and sides to provide tensile stress protection when subjected to external loads. In severe weather conditions, the adhesive force of the sealant is not enough to maintain a stable connection, and the laminated part is prone to falling off due to wind or other external forces. This design significantly reduces the wind resistance of the module, and cannot guarantee long-term stability in various environments. SUMMARY

[0004] The utility model aims at providing a dust-proof photovoltaic module frame to solve the problem of dust accumulation at the lower end of the photovoltaic module assembled with an A-face frame in the prior art during power station application, which reduces the power generation efficiency and forms hot spots, and the problem of poor wind and snow load bearing capacity of the photovoltaic module assembled with an overall A-face-free frame.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] Please see Figures 1 to 4 An embodiment of this application provides a frame for an anti-dust-accumulation photovoltaic module, used for mounting laminates. The anti-dust-accumulation photovoltaic module frame is a rectangular frame formed by a set of oppositely arranged frames without an A-side and a set of oppositely arranged frames with an A-side, connected by corner brackets 3. The frames without an A-side 1 have first chamfers 18 at both ends in the length direction. The corner brackets 3 are conventional structures and will not be described in detail here.

[0052] The A-side borderless 1 includes an A-side borderless body 11, a first extension wall 12, and a corner tooth structure.

[0053] Specifically, the first extension wall 12 extends upward from the outer edge of the upper surface of the body 11 without an A-side border, and extends along the length direction of the body 11 without an A-side border. The first extension wall 12 does not exceed the upper surface of the laminate.

[0054] The angular tooth structure includes a first angular tooth 13, a second angular tooth 14, and a third angular tooth 15, which are arranged sequentially from bottom to top on the inner surface of the first extension wall 12. The first angular tooth 13, the second angular tooth 14, and the third angular tooth 15 extend toward the laminate and along the length direction of the body 11 without the A-side frame. The third angular tooth 15 does not exceed the upper surface of the laminate.

[0055] Two first overflow grooves 16 are formed between the first angle tooth 13, the second angle tooth 14, and the third angle tooth 15 respectively. The cross-sectional area of ​​at least one first overflow groove 16 gradually decreases from the first extension wall 12 toward the laminate along the depth direction; or / the depth direction of at least one first overflow groove 16 is not parallel to the horizontal direction, and the cross-sectional area from the first extension wall 12 toward the laminate along the depth direction remains unchanged.

[0056] In some embodiments, a fixing boss 17 is provided on the body 11 without an A-side border. The fixing boss 17 extends from the inner edge of the upper surface of the body 11 without an A-side border in the width direction toward the laminate and extends along the length direction of the body 11 without an A-side border.

[0057] In detail, the upper surface of the fixing boss 17 is flush with the upper surface of the body 11 without an A-side frame, and the lower surface is rounded to the inner side of the body 11 without an A-side frame. By setting the fixing boss 17, the adhesion area between the laminate and the upper surface of the body 11 without an A-side frame can be effectively increased, and the flush upper surface design ensures the flatness of the contact surface, which helps to firmly bond the laminate to the frame and improves the stability and load-bearing capacity of the overall structure. The rounded transition on the lower surface prevents sharp structures from scratching the laminate.

[0058] In some embodiments, along the width of the frameless body 11, the first angle tooth 13 gradually slopes upwards from the first extension wall 12 toward the laminate. Specifically, the lower surface of the first angle tooth 13 is arc-shaped and connects to the upper surface of the frameless body 11. This structural design allows the first angle tooth 13 to effectively engage with the sealant at the bottom to form an anti-detachment latch, which not only enhances the bonding strength between the laminate and the frame but also prevents the component from detaching due to vibration or external forces during use, thus improving the overall structural stability and reliability.

[0059] In some embodiments, in the width direction of the body 11 without the A-side frame, the second angle tooth 14 gradually slopes downward from the first extension wall 12 toward the laminate; or / and is horizontally arranged with the upper surface of the third angle tooth 15, and the lower surface gradually slopes downward from the first extension wall 12 toward the laminate. The downward slope of the second angle tooth 14, in conjunction with the sealant, can increase the contact area with the laminate, forming a more stable anti-loosening snap effect, which helps to improve the fixation and durability of the component. The horizontal arrangement of the upper surface of the third angle tooth 15 can ensure the integrity and aesthetics of the component after assembly.

[0060] In some embodiments, the lengths of the first angle tooth 13, the second angle tooth 14, and the third angle tooth 15 range from 1.5 mm to 2 mm. This application does not impose a specific limitation on this.

[0061] It should be noted that the length direction of the aforementioned frameless A-side border 1 and frameless A-side border body 11 is as follows: Figure 2 As shown by the middle arrow a, the width direction is as follows Figure 2 As indicated by the middle arrow b.

[0062] In some embodiments, the A-side frame 2 includes an A-side frame body 21, a second extension wall 22, and a press-fit edge 23.

[0063] Specifically, the second extension wall 22 extends upward from the outer edge of the upper surface of the A-side frame body 21 and extends along the length direction of the A-side frame body 21. The A-side frame body 21 and the second extension wall 22 are provided with second chamfers 24 at both ends in the length direction. The sum of the angles of the second chamfers 24 and the first chamfers 18 is 90 degrees.

[0064] In some preferred embodiments, the angles of the first chamfer 18 and the second chamfer 24 are both 45 degrees, and this application does not specifically limit this.

[0065] The crimping edge 23 extends from the long extension edge of the second extension wall 22 toward the laminate and extends along the length direction of the body with the A-side frame 21 to cover the end of the adjacent first extension wall 12. The two end faces of the crimping edge 23 in the length direction continuously approach each other from bottom to top, and the end faces of the crimping edge 23 are arc-shaped and connected to the upper surface of the crimping edge 23. The crimping edge 23 is recessed inward from its inner surface to form a second overflow groove 25, which extends along the length direction of the crimping edge 23 and penetrates the two end faces of the crimping edge 23 in the length direction.

[0066] Traditionally, the junction between the frame 2 (with A-side) and the frameless side 1 has a 45° chamfer, which looks abrupt and affects the aesthetics. Furthermore, due to the cutting, handling this component can easily cause scratches. In this application, the end face of the pressing edge 23 is set as a smooth arc surface, making the transition from the frame 2 (with A-side) to the frameless side 1 smoother and more aesthetically pleasing, and preventing skin scratches. The smooth surface also provides a larger contact area, allowing wiping or cleaning tools to more evenly contact the sealant. This helps to more effectively remove sealant overflowing from the second overflow groove 25 without leaving residue at the edges.

[0067] In some embodiments, the upper surface of the crimp edge 23 is arc-shaped and connected to the two long extension edges of the crimp edge 23 to further reduce sharp edges.

[0068] In some embodiments, an inwardly recessed glue reservoir 26 is provided on the upper surface of the A-side frame body 21 near its outer edge. In the width direction of the A-side frame body 21, the depth of the glue reservoir 26 gradually increases from away from the second extension wall 22 toward closer to the second extension wall 22.

[0069] In some embodiments, the A-side frame body 21 includes a hollow main body 211, a first suspended portion 212, and a second suspended portion 213. Specifically, the hollow main body 211 is formed by connecting an inner sidewall and an outer sidewall, and a top wall and a bottom wall, which are disposed opposite to each other. The first suspended portion 212 extends from the end where the top wall connects to the inner sidewall toward the laminate and extends along the length direction of the hollow main body 211. The second suspended portion 213 extends from the end where the bottom wall connects to the inner sidewall toward the laminate and extends along the length direction of the hollow main body 211.

[0070] The two end faces of the second suspended portion 213 in the length direction continuously approach the laminate from the hollow main body portion 211, and the end faces of the second suspended portion 213 are connected by an arc transition to the side edge of the second suspended portion 213 away from the hollow main body portion 211 in the width direction.

[0071] It should be noted that the length direction of the above-mentioned A-side border 2 and A-side border body 21 is as follows: Figure 4 As shown by the middle arrow c, the width direction is as follows Figure 4 As indicated by the middle arrow d.

[0072] Finally, it should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
