Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a photovoltaic frame and photovoltaic equipment. Background Art

[0002] The photovoltaic cell includes a photovoltaic module and a photovoltaic frame arranged on the periphery of the photovoltaic module. The photovoltaic frame includes surface A, surface B, and surface C, wherein surface A is used to include the outer edge of the upper surface of the photovoltaic module, thereby fixing the photovoltaic module to the photovoltaic frame. However, in the above-mentioned photovoltaic frame, a corner is formed between surface A and the photovoltaic module. This corner prevents dust from being washed away from the glass surface of the photovoltaic module by rainwater, resulting in dust accumulation. The accumulation of dust directly affects the luminous efficiency of the photovoltaic cell, and for the entire photovoltaic cell, the obstruction of one or several cells will cause a hot spot effect. Due to the circuit protection of the photovoltaic module itself, a certain string of cells will be discarded, greatly reducing the power of the module.

[0003] To address this issue, some existing photovoltaic modules have eliminated the A-side design, resulting in a smooth upper surface for the photovoltaic cells. This allows dust to wash off the cells with rainwater, preventing dust accumulation. Due to the lack of an A-side fixation, the photovoltaic module and the photovoltaic frame must be secured with glue within the mounting groove where they meet. However, the narrow size of the photovoltaic frame limits the contact area between the glue and the frame, resulting in a weak connection and a high risk of detachment between the photovoltaic module and the frame.

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figure 1As shown, an embodiment of a photovoltaic frame according to the present application includes a frame body 10. The frame body 10 has a mounting groove 20 at its top, which is suitable for mounting a photovoltaic module 100. The mounting groove 20 includes a bottom wall 21 and side walls 22. The bottom wall 21 is provided with a first glue-filling groove 23, and the side walls 22 are provided with a second glue-filling groove 24. The wall surfaces of the first glue-filling groove 23 and / or the second glue-filling groove 24 are concave and convex.

[0028] By utilizing the technical solution of this embodiment, the wall surfaces of the first glue-filling groove 23 of the bottom wall 21 and / or the second glue-filling groove 24 of the side wall 22 of the frame body 10 are configured as concave and convex surfaces. This increases the contact area between the glue and the first glue-filling groove 23 and / or the second glue-filling groove 24, thereby increasing the connection strength and making the connection between the photovoltaic frame and the photovoltaic module 100 more secure. Therefore, the technical solution of this embodiment solves the problem of low connection strength between the photovoltaic accessory and the photovoltaic frame in the prior art, which easily leads to the two being separated.

[0029] It should be noted that the frame body 10 of this embodiment is enclosed into a closed structure, which can be square, polygonal, etc. Figure 1 The structure shown is a schematic cross-sectional view of the frame body 10 .

[0030] like Figure 1 As shown, a mounting groove 20 is provided on the top of the frame body 10. The mounting groove 20 has a bottom wall 21 and a side wall 22. Therefore, the cross-section of the mounting groove 20 is an "L"-shaped structure. Figure 1 It can be seen that during assembly, the outer side surface of the photovoltaic assembly 100 is connected to the side wall 22 , and the edge of the bottom surface of the photovoltaic assembly 100 is connected to the bottom wall 21 .

[0031] Furthermore, the photovoltaic module 100 is bonded to the mounting groove 20 using glue, and therefore a first glue-filling groove 23 is provided on the bottom wall 21, and a second glue-filling groove 24 is provided on the side wall 22. The glue in the first glue-filling groove 23 can bond the edge of the bottom surface of the photovoltaic module 100 to the bottom wall 21, and the glue in the second glue-filling groove 24 can bond the outer side surface of the photovoltaic module 100 to the side wall 22.

[0032] like Figure 1 As shown, in this embodiment, the wall surface of the first glue filling groove 23 is set to a concave-convex surface, thereby increasing the contact area between the glue and the wall surface of the first glue filling groove 23, thereby making the edge of the bottom surface of the photovoltaic component 100 more firmly bonded to the bottom wall 21.

[0033] like Figure 1As shown, in this embodiment, the wall surface of the second glue filling groove 24 is set to a concave-convex surface, thereby increasing the contact area between the glue and the wall surface of the second glue filling groove 24, thereby making the edge of the bottom surface of the photovoltaic component 100 more firmly bonded to the bottom wall 21.

[0034] In some embodiments not shown, only one of the first glue-filling groove 23 and the second glue-filling groove 24 may be configured as a concave-convex wall surface. For example, only the wall surface of the first glue-filling groove 23 may be configured as a concave-convex wall surface, or only the wall surface of the second glue-filling groove 24 may be configured as a concave-convex wall surface.

[0035] like Figure 1 As shown, in the technical solution of this embodiment, the bottom surface of the first glue filling groove 23 and / or the second glue filling groove 24 is a curved surface.

[0036] For the sake of convenience, the following Figure 1 The direction shown is used to illustrate the structures of the first glue filling groove 23 and the second glue filling groove 24 .

[0037] like Figure 1 As shown, the horizontal surface of the first glue filling groove 23 is set to a concave-convex surface, and the convex part and the concave part are both arc-shaped curved surfaces. The concave-convex surface of the first glue filling groove 23 can be a rough surface or a wavy surface.

[0038] like Figure 1 As shown, the second glue filling groove 24 includes a top surface and a side surface, wherein the top surface is a convex surface, and the intersection of the top surface and the side surface is a concave surface. The convex surface and the concave surface of the second glue filling groove 24 are both arc-shaped curved surfaces. The side surface of the second glue filling groove 24 is roughly a vertical plane. Figure 1 Those skilled in the art will appreciate that the raised surface of the top surface can provide a horizontal limiting effect on the solidified glue, thereby increasing the bonding force between the glue and the second glue-filling groove 24 and increasing the connection strength.

[0039] In some embodiments not shown, the above-mentioned concave-convex surface can also be formed in other ways. For example, the concave-convex surface can be a serrated structure formed by a straight surface, or a rough surface structure formed by dot-shaped protrusions, etc.

[0040] like Figure 1 As shown, in the technical solution of this embodiment, the first glue filling groove 23 and the second glue filling groove 24 are connected at the intersection of the bottom wall 21 and the side wall 22. That is, the first glue filling groove 23 and the second glue filling groove 24 are connected at the corner position of the installation groove 20.

[0041] This arrangement allows the corners of the mounting groove 20 to also be filled with glue. After the glue solidifies, the contact area with the mounting groove 20 is larger, so the bonding force with the mounting groove 20 is greater, making the connection between the photovoltaic module 100 and the frame body 10 more stable.

[0042] In some embodiments not shown, the first glue-filling groove 23 and the second glue-filling groove 24 may not be connected at the junction of the bottom wall 21 and the side wall 22. That is, the first glue-filling groove 23 and the second glue-filling groove 24 are not connected.

[0043] like Figure 1 As shown, in the technical solution of this embodiment, the photovoltaic assembly 100 includes a glass panel, and the outer surface of the glass panel is flush with the top of the side wall 22. This arrangement prevents dust from accumulating on the glass panel.

[0044] Specifically, the frame body 10 in this embodiment adopts a structure without an A surface, that is, the outer surface of the photovoltaic module 100 is flush with the top of the frame body 10. Figure 1 As can be seen, the outermost structure of the photovoltaic module 100 is a glass panel, the outer surface of which is flush with the top of the side wall 22. In other words, the outer surface formed by the photovoltaic module 100 and the frame body 10 is a flat surface. Therefore, dust on the glass panel is washed away by rainwater and does not accumulate on the glass panel, preventing the cells from being blocked and the cell strings from being discarded.

[0045] like Figure 1 As shown, in the technical solution of this embodiment, the frame body 10 also includes a first supporting vertical wall 11 located on the inner side, the first supporting vertical wall 11 is located below the mounting groove 20, the bottom wall 21 extends toward the inner side of the frame body 10, and the end of the bottom wall 21 protrudes inward from the first supporting vertical wall 11.

[0046] like Figure 1 As shown, and Figure 1 The first supporting vertical wall 11 extends in the vertical direction and is supported at the lower side of the mounting groove 20. The end of the bottom wall 21 of the mounting groove 20 that is away from the side wall 22 extends inward and extends from the bottom wall 21 of the mounting groove 20. Figure 1 It can be seen that the end of the bottom wall 21 extends beyond the first supporting vertical wall 11. Figure 1 The length in the left and right directions as shown increases the contact area between the glue and the bottom wall 21 and the photovoltaic module 100, making the connection between the photovoltaic module 100 and the bottom wall 21 more stable.

[0047] In some embodiments not shown, the end of the bottom wall 21 of the mounting groove 20 may also be arranged to be flush with the first supporting vertical wall 11 .

[0048] like Figure 1 As shown, in the technical solution of this embodiment, the frame body 10 further includes a second supporting vertical wall 12 located on the outside. The second supporting vertical wall 12 and the first supporting vertical wall 11 are arranged opposite to each other and form the outer side surface of the frame body 10.

[0049] from Figure 1 As can be seen, the second vertical support wall 12 is disposed opposite the first vertical support wall 11 and is located outside the first vertical support wall 11. The second vertical support wall 12 is parallel to the first vertical support wall 11, with their lower ends aligned, and the upper end of the second vertical support wall 12 protruding beyond the upper end of the first vertical support wall 11. Those skilled in the art will appreciate that, in practice, the outer surface of the second vertical support wall 12 forms the B surface of the frame body 10.

[0050] Further, from Figure 1 It can be seen that the portion of the upper end of the second supporting vertical wall 12 protruding from the first supporting vertical wall 11 has an inner side surface forming the side wall 22 of the above-mentioned installation groove 20 .

[0051] Optionally, the second glue-filling groove 24 is provided on the second supporting vertical wall 12 .

[0052] Further, from Figure 1 It can be seen that the outer surface of the glass panel of the photovoltaic assembly 100 is flush with the top of the second supporting vertical wall 12, that is, a form without an A surface is formed.

[0053] like Figure 1 As shown, in the technical solution of this embodiment, the frame body 10 also includes a supporting bottom wall 13 , which is connected below the first supporting vertical wall 11 and the second supporting vertical wall 12 , and forms the bottom surface of the frame body 10 .

[0054] from Figure 1 As can be seen, the support bottom wall 13 is arranged perpendicular to both the first support vertical wall 11 and the second support vertical wall 12. One end of the support bottom wall 13 is connected to the bottom end of the second support vertical wall 12, and the other end of the support bottom wall 13 extends inward and protrudes beyond the first support vertical wall 11. The bottom end of the first support vertical wall 11 is connected to the support bottom wall 13. Those skilled in the art will appreciate that the bottom surface of the support bottom wall 13 forms the C-surface of the frame body 10.

[0055] like Figure 1 As shown, in the technical solution of this embodiment, the frame body 10 also includes a supporting top wall 14, the first end of the supporting top wall 14 is connected to the second supporting vertical wall 12, the first supporting vertical wall 11 is connected to the bottom of the supporting top wall 14, and the second end of the supporting top wall 14 extends inward to protrude from the first supporting vertical wall 11, wherein the second supporting vertical wall 12 and the supporting top wall 14 form an installation groove 20.

[0056] from Figure 1 It can be seen that the support top wall 14 is parallel to the support bottom wall 13, that is, the support top wall 14 is perpendicular to the first support vertical wall 11 and the second support vertical wall 12. The first end of the support top wall 14 ( Figure 1 The right end shown in the figure) is connected to the inner side of the second supporting vertical wall 12, and the connection point is flush with the top of the first supporting vertical wall 11. The second end of the supporting top wall 14 ( Figure 1 The left end shown in the figure extends inward, and the top of the first supporting vertical wall 11 is connected to the lower surface of the supporting top wall 14. Those skilled in the art will understand that the upper surface of the supporting top wall 14 forms the bottom wall 21 of the above-mentioned mounting groove 20.

[0057] Optionally, the first glue-filling groove 23 is provided on the upper surface of the supporting top wall 14 .

[0058] Optionally, the first glue-filling groove 23 and the second glue-filling groove 24 are connected at the intersection of the supporting top wall 14 and the second supporting vertical wall 12 .

[0059] from Figure 1 It can be seen that the second end of the support top wall 14 extends to protrude beyond the first support vertical wall 11, thereby increasing the length of the bottom wall 21 and increasing the contact area between the glue, the photovoltaic module 100, and the bottom wall 21. Furthermore, the second end of the bottom wall 21 extends to an end that does not protrude beyond the support bottom wall 13.

[0060] Optionally, the frame body 10 is made of aluminum. And preferably, the frame body 10 is made of aluminum alloy profile.
