Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a flexible frame of a photovoltaic module. Background Art

[0002] Solar panel protective frames protect the panels from environmental damage and provide support and stability. Existing solar panel protective frames are typically assembled from aluminum alloy profiles with a cavity structure, into which the edges of the solar panel are inserted for support. However, for flexible solar panels, using aluminum alloy profiles as protective frames, a rigid material, can compromise the panels' flexibility and prevent them from being easily bent or attached to curved surfaces.

[0003] Chinese patent CN 223052980 U discloses a flexible protective frame for a flexible solar panel, which includes a frame, a sealing strip and two first button buckles. The frame is made of flexible material and has sufficient flexibility. A groove is concave on the inner peripheral side of the frame for accommodating the edge of the solar panel and providing support. The frame is provided with a slot, which is connected to the groove for inserting the flexible solar panel into the frame. The outer peripheral side of the frame is concave with a accommodating groove at the edge of the slot. The inner walls at both ends of the accommodating groove are concave with first mounting grooves. The buckle bodies of the two first button buckles are respectively fixed in the first mounting grooves, and the lock heads of the two first button buckles are respectively fixed to the two ends of the sealing strip.

[0004] However, since the flexible photovoltaic panels are relatively soft, it is inconvenient to install the flexible photovoltaic panels in the frame according to the above patent, and the above patent does not have a mechanism to buffer the photovoltaic panels. When the photovoltaic panels are impacted by external forces, the force directly impacts the surface of the photovoltaic panels, and the photovoltaic panels are prone to cracks or breakage, which affects the use of the photovoltaic panels.

[0019] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-8 The present invention provides a technical solution: a flexible frame of a photovoltaic module, comprising: an upper fixing frame 1, a lower fixing frame 2 and a buffer frame 3. The upper fixing frame 1 and the lower fixing frame 2 are both rectangular and of the same size. The upper fixing frame 1 and the lower fixing frame 2 are both made of elastic rubber, so that the upper fixing frame 1 and the lower fixing frame 2 can be bent and deformed, and can be adaptively bent and mounted on a curved surface. The upper fixing frame 1 is fixedly mounted on the upper end of the lower fixing frame 2, and the buffer frame 3 is fixedly mounted on the lower end of the lower fixing frame 2. The photovoltaic panel 22 is fixed on the upper fixing frame 1. Between the upper fixing frame 1 and the lower fixing frame 2, the upper fixing frame 1 and the lower fixing frame 2 clamp and fix the photovoltaic panel 22. The upper end of the upper fixing frame 1 is provided with a mounting groove 2 18, and a sealing frame 21 is fixedly bonded at the upper end of the mounting groove 2 18 for sealing the mounting groove 2 18. An elastic metal plate 2 19 is provided in the mounting groove 2 18. The mounting groove 2 18 and the elastic metal plate 2 19 are both rectangular. The elastic metal plate 2 19 is located in the mounting groove 2 18. The lower end of the upper fixing frame 1 is provided with a placement groove 2 14, and the placement groove 2 14 is rectangular.

[0021] The upper end of the lower fixed frame 2 is provided with a placement groove 4, which is rectangular. The lower end of the lower fixed frame 2 is provided with a mounting groove 8, and an elastic metal plate 10 is installed in the mounting groove 8. The mounting groove 8 and the elastic metal plate 10 are both rectangular. The elastic metal plate 10 is located in the mounting groove 8. The photovoltaic panels 22 are arranged in the placement groove 4 and the placement groove 2 14. Adhesive is applied to the edges of the photovoltaic panels 22 to fix them in the placement groove 4 and the placement groove 2 14. Several circular holes 7 are evenly opened on the side wall of the lower fixed frame 2, and several circular holes 17 corresponding to the circular holes 7 are evenly opened on the side wall of the upper fixed frame 1. The elastic metal plate 10 Several circular holes 17 and 11 are evenly opened on the side wall, and several circular holes 20 corresponding to the circular holes 3 17 are opened on the side wall of the elastic metal plate 2. When the upper fixing frame 1 is placed on the upper end of the lower fixing frame 2, the circular holes 17, 11, 17 and 20 are connected and fixed by bolts to fix the elastic metal plate 10 and the elastic metal plate 2 19 together. At the same time, the upper fixing frame 1 is fixed to the upper end of the lower fixing frame 2 to complete the clamping of the photovoltaic panel 22. The setting of the elastic metal plate 10 and the elastic metal plate 2 19 increases the toughness and firmness of the upper fixing frame 1 and the lower fixing frame 2, so that they can be better fixed on the curved surface.

[0022] The buffer frame 3 is rectangular, and an adhesive layer 25 is provided at the lower end of the buffer frame 3. The lower end of the adhesive layer 25 is provided with isolation paper. By tearing off the isolation paper, the frame can be adhered to the surface of the object through the adhesive layer 25, which is convenient for installing the frame. The buffer frame 3 is made of elastic rubber, and a buffer cavity 24 is provided at the inner end of the buffer frame 3. The buffer frame 3 is fixedly installed at the lower port of the installation slot 8, which is used to seal the lower port of the installation slot 8, and a cavity is provided between the elastic metal plate 10 and the buffer frame 3. The cavity can increase the elastic deformation ability of the lower fixed frame 2, and the buffer cavity 24 increases the deformation ability of the buffer frame 3. When the photovoltaic panel 22 is impacted by external force, the photovoltaic panel 22 will transfer the force it receives to the lower fixed frame 2, and the lower fixed frame 2 absorbs part of the impact force through elastic deformation, and then transfers the other part of the impact force to the buffer frame 3. The buffer frame 3 absorbs the other part of the impact force through deformation, thereby buffering the photovoltaic panel 22, giving it a certain impact resistance. The lower fixed frame 2 has a buffering function for the photovoltaic panel 22.

[0023] Specifically, by applying glue on the edges of the photovoltaic panel 22, and then placing it in the placement groove 2 14, then placing the upper fixing frame 1 on the upper end of the lower fixing frame 2, and making several round holes connected and aligned, and fixing it with bolts, the upper fixing frame 1 is firmly fixed to the upper end of the lower fixing frame 2, and the edges of the photovoltaic panel 22 are squeezed to make the glue more tightly adhered. After a period of time, the glue is dried by tearing off the isolation paper, and the frame can be adhered to the surface of the object through the glue layer 25, which is convenient for installing the photovoltaic panel 22 and can buffer the photovoltaic panel 22, thereby improving the impact resistance of the photovoltaic panel 22.

[0024] like Figure 3-Figure 6 As shown, in some embodiments, an extension plate 2 15 is fixedly installed on the inner end of the placement groove 14, and an extension plate 5 is fixedly installed on the inner end of the placement groove 14. Both the extension plate 15 and the extension plate 2 15 are rectangular, and the upper end of the extension plate 2 15 is flush with the upper end of the placement groove 14, and the upper end of the extension plate 5 is flush with the upper end of the placement groove 4. A rectangular limiting groove 16 is provided on the outer side of the inner wall of the placement groove 14, and a rectangular limiting groove 2 16 is provided on the outer side of the inner wall of the placement groove 14. Rectangular limiting rubber strips 23 are fixedly installed on the outer sides of the upper and lower ends of the photovoltaic panel 22. When the photovoltaic panel 22 is located in the placement groove 2 14 and the placement groove 14, the limiting rubber strips 23 at the upper and lower ends of the photovoltaic panel 22 are respectively located in the limiting groove 2 16 and the limiting groove 16 to fix the photovoltaic panel 22.

[0025] Specifically, by setting up extension plate 1 5 and extension plate 2 15, the contact area between placement groove 1 4, placement groove 2 14 and the edge of photovoltaic panel 22 is increased, which facilitates fixing the photovoltaic panel 22 more firmly. At the same time, the limiting rubber strip 23 is respectively located in limiting groove 2 16 and limiting groove 1 6 to further increase the installation firmness of photovoltaic panel 22.

[0026] like Figure 3-Figure 5 As shown, in some embodiments, a supporting component is provided at the inner end of the lower fixed frame 2, and the supporting component is used to support the photovoltaic panel 22. The supporting component includes a rectangular groove 9, an elastic metal frame 12 and a rubber pad 13. There are several rectangular grooves 9, and they are evenly opened at the lower end of the lower fixed frame 2. The rectangular groove 9 is connected to the inner end of the mounting groove 8. The outer end of the elastic metal frame 12 is inserted into the rectangular groove 9 and contacts the lower end of the elastic metal plate 10. The elastic metal frame 12 is fixedly connected to the elastic metal plate 10 by bolts. The rubber pad 13 is fixedly installed at the upper end of the elastic metal frame 12. The rubber pad 13 contacts the lower end of the photovoltaic panel 22 and supports the photovoltaic panel 22. More specifically, the elastic metal frame 12 reinforces the inner side of the upper fixed frame 1 and the lower fixed frame 2 to prevent the inner ends of the upper fixed frame 1 and the lower fixed frame 2 from being severely deformed when bending, thereby tearing the photovoltaic panel 22 or causing the photovoltaic panel 22 to fall off. At the same time, the rubber pad 13 contacts the lower end of the photovoltaic panel 22 to support it.

[0027] In actual use, the support components are fixedly installed on the inner side of the lower fixed frame 2, glue is applied on the edges of the photovoltaic panel 22, and then it is placed in the placement groove 2 14, and then the upper fixed frame 1 is placed on the upper end of the lower fixed frame 2, the lower end of the photovoltaic panel 22 is in contact with the upper end of the rubber pad 13, and several round holes are connected and aligned, and fixed by bolts, the upper fixed frame 1 is firmly fixed to the upper end of the lower fixed frame 2, and the edges of the photovoltaic panel 22 are squeezed to make the glue more tightly adhered. After the glue dries for a period of time, the isolation paper is torn off, and the frame can be bonded to the surface of the object through the glue layer 25, which is convenient for installing the photovoltaic panel 22 and can buffer the photovoltaic panel 22, thereby improving the impact resistance of the photovoltaic panel 22.

[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
