[0002] Currently, the frame of a conventional photovoltaic module primarily serves to protect the laminated components and provide load-bearing capacity; it also mainly functions for installation and fixation. During the transportation of photovoltaic modules, paper corner protectors are often used to protect the frame from friction and collisions.

[0003] Currently, most photovoltaic modules have a C-side in their frame (combined with...). Figure 1 As shown, the frame of a photovoltaic module includes the A-side, B-side, and C-side connected in sequence; however, as the requirements for the power increase on the back side of photovoltaic modules become higher and higher, the use of photovoltaic modules without C-side frames with lower shading rate is also increasing. However, the existing paper corner protectors have the following defects: (1) The existing paper corner protector structure design will be on the B-side of the photovoltaic module, and the corner protector cannot be pasted on the edge of the B-side of the photovoltaic module. (2) The existing plastic corner protectors are integrally molded structures, which are larger in size, inconvenient for storage and transportation, and more expensive.

However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0038] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0039] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0040] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0041] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings.

Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0045] Example 1

[0046] The following is combined with Figures 1-3 This application provides a detailed description of a frame corner protection structure.

[0047] Combination Figure 2As shown, this application provides a frame corner protector structure, including a first panel 1, a second panel 2, a first connecting plate 6, and a second connecting plate. Both the first panel 1 and the second panel 2 are right-angled triangles, each having a right angle. Furthermore, the first panel 1 has a first right-angled side 3 and a second right-angled side 11 that are perpendicular to each other, and the second panel 2 has a second right-angled side 4 and a second right-angled side 12 that are perpendicular to each other. It is worth noting that this embodiment uses the example of the first panel 1 and the second panel 2 being right-angled triangles for detailed explanation; however, the first panel 1 and the second panel 2 are not limited to right-angled triangles and can also be squares, rectangles, etc.

[0048] Specifically, the first panel 1 and the second panel 2 are symmetrically arranged about a reference line parallel to the first right-angled side 3, so that a gap 5 is formed between the two first panels 1 and the second panel 2; the first connecting plate 6 is disposed in the gap 5 and away from the right-angled end 7 of the panel; furthermore, combined with Figure 1 As shown, the dimension of the first connecting plate 6 along the first right angle 3 is smaller than the dimension of the first right angle 3, and the dimension of the first connecting plate 6 along the second right angle 4 is smaller than the dimension of the second right angle 4. In other words, the first connecting plate 6 does not completely fill or cover the above-mentioned gap 5.

[0049] Specifically, the second connecting plate includes a first connecting portion 8 and a second connecting portion 9; wherein the first connecting plate 6 is connected to the first second right-angled side 11, the second connecting portion 9 is connected to the second second right-angled side 12, and both the first connecting portion 8 and the second connecting portion 9 are far away from the right-angled end 7; in other words, the dimension of the first connecting portion 8 along the extension direction of the first second right-angled side 11 is smaller than the length of the first second right-angled side 11, and the dimension of the second connecting portion 9 along the extension direction of the second second right-angled side 12 is smaller than the length of the second right-angled side.

[0050] In summary, when the first panel 1 and the second panel 2 are folded perpendicular to the first connecting plate 6, making the two panels parallel, and the first connecting part 8 and the second connecting part 9 are folded perpendicular to the first panel 1 and the second panel 2 respectively, this application will form an angular corner protection structure, and a gap space 13 will be formed at the right-angle end 7 of the first panel 1 and the second panel 2; combined with Figure 1 As shown, this empty space 13 corresponds exactly to the B-side area of ​​the photovoltaic module. In other words, by adopting the structure of this application, the B-side area is exposed, so that barcodes can be affixed to the B-side area.

[0051] Furthermore, combining Figure 2As shown, during the actual folding process, the first panel 1 is folded inwards towards the paper so that it is perpendicular to the first connecting plate 6, and the second panel 2 is folded inwards towards the paper so that it is perpendicular to the first connecting plate 6. Thus, the first panel 1 and the second panel 2 are parallel. Furthermore, the first connecting portion 8 is folded inwards towards the paper so that it is perpendicular to the first panel 1, and the second connecting portion 9 is folded inwards towards the paper so that it is perpendicular to the second panel 2. After folding, the first connecting portion 8 and the second connecting portion 9 overlap, forming a triangular corner protector structure after folding.

[0052] In addition, the first connecting plate 6, the second connecting plate, the first panel 1 and the second panel 2 of this application are all made of paper material. Compared with the existing plastic material, this paper material is lower in cost and lighter, making it convenient to transport.

[0053] In this embodiment, specifically, in conjunction with Figure 2 As shown, the sum of the dimensions of the first connecting part 8 along the first right angle side 3 and the second connecting part 9 along the first right angle side 3 is greater than the dimension of the first connecting plate 6 in the direction perpendicular to the first right angle side 3. In other words, when the first connecting part 8 is folded perpendicular to the first second right angle side 11 and the second connecting part 9 is folded perpendicular to the second second right angle side 12, the first connecting part 8 and the second connecting part 9 will overlap.

[0054] Furthermore, when the first connecting part 8 is folded perpendicular to the first second right-angle side 11 and the second connecting part 9 is folded perpendicular to the second second right-angle side 12, since the first connecting part 8 and the second overlapping part are overlapped together, the overlap may be unreliable and loose. Therefore, in order to solve this technical problem, the frame corner protection structure provided in this application also includes a locking member.

[0055] Combination Figure 2 As shown, specifically, the locking member includes a first locking part 14 and a second locking part 15, wherein the first locking part 14 is disposed on the first connecting part 8 and is away from the edge of the first second right-angled side 11, and the second locking part 15 is disposed on the second connecting part 9 and is away from the edge of the second second right-angled side 12.

[0056] In actual use, the first locking part 14 and the second locking part 15 are mutually self-locking so that when the first connecting part 8 and the second connecting part 9 are joined together, the first connecting part 8 and the second connecting part 9 can be mutually self-locked together, thus fixing the first connecting part 8 and the second connecting part 9 together and preventing the two from becoming loose.

[0057] Furthermore, combining Figure 2As shown, the first locking part 14 is the first opening 16 formed on the first connecting part 8, and the second locking part 15 is the second opening 17 formed in the second connecting part 9; preferably, the first connecting part 8 and the second connecting part 9 are symmetrically arranged about the reference line mentioned above; in addition, the first opening 16 and the second opening 17 both extend along the extension direction of the first right angle side 3, and the first opening 16 and the second opening 17 are also symmetrical about the reference line mentioned above. The first opening 16 is equivalent to dividing the first connecting part 8 into upper and lower parts away from the edge of the first second right angle side 11, and the second opening 17 is equivalent to dividing the second connecting part 9 into upper and lower parts away from the edge of the second second right angle side 12. In actual use, the first opening 16 of the first connecting part 8 and the second opening 17 of the second connecting part 9 are intersected. In this way, the upper part of the second connecting part 9 will press against the upper part of the first connecting part 8, and the lower part of the first connecting part 8 will press against the lower part of the second connecting part 9. Therefore, the first locking part 14 and the second locking part 15 are mutually self-locked through the first opening 16 and the second opening 17, thereby achieving a stable connection between the first connecting part 8 and the second connecting part 9.

[0058] In this embodiment, specifically, in conjunction with Figure 2 As shown, the first connecting part 8 is the third connecting plate 18, and the second connecting part 9 is the fourth connecting plate 19; creases 20 are provided at the connection points of the third connecting plate 18 and the first second right-angled edge 11 of the first panel 1, and at the connection points of the fourth connecting plate 19 and the second second right-angled edge 12 of the second panel 2; the creases 20 allow the third connecting plate 18 to be folded perpendicular to the first second right-angled edge 11 and the fourth connecting plate 19 to be folded perpendicular to the second second right-angled edge 12.

[0059] In this embodiment, further, combined with Figure 2 As shown, one end of the first connecting plate 6 is connected to the first right-angled edge 3 of the first panel 1, and the other end of the connecting plate is connected to the second right-angled edge 4 of the second panel 2. A crease 20 is provided at the connection points between the first connecting plate 6 and the first right-angled edge 3 and between the first connecting plate 6 and the second right-angled edge 4. The crease 20 allows the first panel 1 to be folded perpendicular to the first connecting plate 6 and the second panel 2 to be folded perpendicular to the first connecting plate 6.

[0060] In this embodiment, since region B (which includes two mutually perpendicular end faces) has a groove structure, the first connecting plate 6 is also configured as a foldable structure to accommodate the groove structure. Specifically, in conjunction with Figure 2 The first connecting plate 6 shown has a plurality of crease portions 20 arranged at intervals, and the crease portions 20 extend along a direction parallel to the first right-angled side 3.

[0061] Furthermore, combined with Figure 2 As shown, five folded sections 20 are arranged at intervals on the first connecting plate 6. The five folded sections 20 divide the first connecting plate 6 into a first folded plate 21, a second folded plate 22, a third folded plate 23, a fourth folded plate 24 and a fifth folded plate 25 along the direction from the first right angle 3 to the second right angle 4.

[0062] In practical use, combined with Figure 3 As shown, the first folding plate 21 is folded perpendicularly to the first panel 1 along the crease 20, the second folding plate 22 is folded perpendicularly to the first folding plate 21 along the crease 20, the third folding plate 23 is folded perpendicularly to the second folding plate 22 along the crease 20, the fourth folding plate 24 is folded perpendicularly to the third folding plate 23 along the crease 20, and the fifth folding plate 25 is folded perpendicularly to the fourth folding plate 24 along the crease 20. This makes the first folding plate 21, the second folding plate 22, the third folding plate 23, the fourth folding plate 24, and the fifth folding plate 25 form a groove that matches the groove structure of surface B, thereby allowing the first connecting plate to fit well against surface B, making the structure more robust.

[0063] It is worth noting that, due to the different dimensions of the various sides of the B-side groove structure of different photovoltaic modules, it is possible to design first folded plate 21, second folded plate 22, third folded plate 23, fourth folded plate 24 and fifth folded plate 25 with different dimensions.

[0064] In addition, since different photovoltaic modules may have a continuous groove structure on their B side, a first connecting plate 6 with more creases 20 can be designed so that it can be folded to fit the first connecting plate 6 with the continuous groove structure.

[0065] In this embodiment, further, combined with Figure 2 As shown, both the third connecting plate 18 and the fourth connecting plate 19 are provided with a plurality of spaced creases 20, and the crease lines extend along a direction parallel to the first second right-angled side 11.

[0066] Furthermore, combined with Figure 2 As shown, the third connecting plate 18 has three folded sections 20 spaced apart, dividing it into a sixth folded plate 26, a seventh folded plate 27, and an eighth folded plate 28. The sixth folded plate 26 is close to the first second right-angled edge 11, while the eighth folded plate 28 is away from the first second right-angled edge 11. The fourth connecting plate 19 has three folded sections 20 spaced apart, dividing it into a ninth folded plate 29, a tenth folded plate 30, and an eleventh folded plate 31. The ninth folded plate 29 is close to the second second right-angled edge 12, while the eleventh folded plate 31 is away from the second second right-angled edge 12.

[0067] In practical use, combined with Figure 3 As shown, the sixth folding plate 26 is folded perpendicularly to the first panel 1 along the crease 20, the seventh folding plate 27 is folded perpendicularly to the sixth folding plate 26 along the crease 20, the eighth folding plate 28 is folded perpendicularly to the seventh folding plate 27 along the crease 20, the ninth folding plate 29 is folded perpendicularly to the second panel 2 along the crease 20, the tenth folding plate 30 is folded perpendicularly to the ninth folding plate 29 along the crease 20, and the eleventh folding plate 31 is folded perpendicularly to the tenth folding plate 30 along the crease 20. The eighth folding plate 28 and the eleventh folding plate 31 will overlap.

[0068] In addition, the eighth folding plate 28 has a first opening 16, and the eleventh folding plate 31 has a second opening 17. The first opening 16 of the eighth folding plate 28 and the second opening 17 of the eleventh folding plate 31 intersect each other. In this way, the upper part of the eighth folding plate 28 will press against the upper part of the eleventh folding plate 31, and the lower part of the eighth folding plate 28 will press against the lower part of the eleventh folding plate 31. Therefore, the first opening 16 and the second opening 17 realize the mutual self-locking of the eighth folding plate 28 and the eleventh folding plate 31, thereby realizing the stable connection between the first connecting part 8 and the second connecting part 9.

[0069] It is worth noting that, due to the different dimensions of the various faces of the groove structure in region B of different photovoltaic modules, sixth fold plate 26, seventh fold plate 27, eighth fold plate 28, ninth fold plate 29, tenth fold plate 30 and eleventh fold plate 31 with different dimensions can be designed.

[0070] In addition, since different photovoltaic modules may have a continuous groove structure on their B side, a third connecting plate 18 and a fourth connecting plate 19 with more creases 20 can be designed, so that the third connecting plate 18 and the fourth connecting plate 19 with the continuous groove structure can be folded out.

[0071] In this embodiment, the first preferred structure for the crease portion 20 is: the crease portion 20 is a crease line, that is, crease lines are drawn on the first panel 1, the second panel 2, the first connecting plate 6, the third connecting plate 18 and the fourth connecting plate 19. The crease lines are equivalent to folding reference lines, and folding can be done according to these crease lines.

[0072] In this embodiment, the first preferred structure for the crease portion 20 is: the crease portion 20 is a series of discontinuous points with holes arranged at intervals, that is, holes are arranged at intervals on the first panel 1, the second panel 2, the first connecting plate 6, the third connecting plate 18 and the fourth connecting plate 19, and folding can be performed according to these discontinuous points with holes.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
