Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0020] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0021] In the various figures of this application, for ease of illustration, certain dimensions of structures or parts may be exaggerated relative to other structures or parts; therefore, they are only used to illustrate the basic structure of the subject matter of this application.

[0022] Please see Figure 1 This application provides a photovoltaic module packaging corner protector, including a main body 1, a first connecting part 2 and a second connecting part 3.

[0023] In this embodiment, the corner protectors of the photovoltaic module packaging are made of paper material, such as cardboard or corrugated paper. The first connecting part 2 and the second connecting part 3 are respectively connected to the main body part 1.

[0024] In some embodiments, in conjunction with reference Figure 2 As shown, the main body 1 has a side plate 11, a first panel 12 and a second panel 13, with the first panel 12 and the second panel 13 connected to opposite sides of the side plate 11.

[0025] In this embodiment, the side panel 11 can be rectangular. The first panel 12 can be a right triangle (e.g., an equilateral right triangle). The second panel 13 can be a right triangle (e.g., an equilateral right triangle).

[0026] In some embodiments, the first connecting part 2 is connected to the first panel 12, and the first connecting part 2 has a first buckle plate 21.

[0027] In this embodiment, the first connecting part 2 is connected to the right-angled edge of the first panel 12.

[0028] In some embodiments, the second connecting part 3 is connected to the second panel 13, and the second connecting part 3 has a second snap plate 31.

[0029] In this embodiment, the second connecting part 3 is connected to the right-angled edge of the second panel 13.

[0030] In some embodiments, the second snap plate 31 is snapped into place with the first snap plate 21.

[0031] In this embodiment, the first connecting part 2 and the second connecting part 3 are detachably connected, facilitating the assembly and disassembly of the photovoltaic module packaging corner protectors. Specifically, the first connecting part 2 and the second connecting part 3 can be fixed by interlocking the second snap-fit ​​plate 31 with the first snap-fit ​​plate 21. Furthermore, the first connecting part 2 and the second connecting part 3 can be separated by disengaging the second snap-fit ​​plate 31 from the first snap-fit ​​plate 21.

[0032] In some embodiments, the outer contour of at least one of the first snap plate 21 and the second snap plate 31 is configured as an arc shape.

[0033] In this embodiment, the outer contour of the first buckle plate 21 and / or the outer contour of the second buckle plate 31 are configured as arcs.

[0034] In this embodiment, since the outer contour of at least one of the first buckle plate 21 and the second buckle plate 31 is configured as an arc, the first buckle plate 21 and the second buckle plate 31 are more smoothly connected during the buckling process, so that the first connecting part 2 and the second connecting part 3 are less likely to get stuck when they are connected, which facilitates the assembly of the photovoltaic module packaging corner protectors.

[0035] In this embodiment, the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31 are engaged smoothly during the snap-fit ​​process, and damage to the paper photovoltaic module packaging corner protectors can be avoided when they are snapped together.

[0036] In some embodiments, the outer contour of the first snap plate 21 is configured as an arc, and the outer contour of the second snap plate 31 is configured as an arc.

[0037] In this embodiment, the outer contours of both the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31 are configured as arc shapes, resulting in a smoother engagement between the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31. Furthermore, after engagement, the engagement strength between the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31 is high, making it difficult for the first connecting part 2 and the second connecting part 3 to separate.

[0038] In other embodiments, one of the outer contours of the first snap plate 21 and the second snap plate 31 may be configured as an arc shape, while the other of the outer contours of the first snap plate 21 and the second snap plate 31 may be configured as another shape (e.g., a straight line or an "L" shape), which can reduce the manufacturing difficulty of photovoltaic module packaging corner protectors.

[0039] In some embodiments, in conjunction with reference Figure 2 and Figure 3 As shown, the first buckle plate 21 has a first central angle A1, and the second buckle plate 31 has a second central angle A2.

[0040] In this embodiment, the first central angle A1 is the central angle of the arc-shaped outer contour of the first snap-on plate 21. The second central angle A2 is the central angle of the arc-shaped outer contour of the second snap-on plate 31.

[0041] In some embodiments, continue to refer to Figure 2 and Figure 3As shown, the first buckle plate 21 has a first radius R1, and the second buckle plate 31 has a second radius R2.

[0042] In this embodiment, the first radius R1 is the radius of the arc-shaped outer contour of the first snap-fit ​​plate 21. The second radius R2 is the radius of the arc-shaped outer contour of the second snap-fit ​​plate 31.

[0043] In some embodiments, the first central angle A1 is equal to the second central angle A2; and / or the first radius R1 is equal to the second radius R2.

[0044] In this embodiment, when the first central angle A1 and the second central angle A2 are equal, the angular travel of the first buckle plate 21 and the second buckle plate 31 during the buckling process is equal, that is, the angles at which the first buckle plate 21 and the second buckle plate 31 rotate around their own center are the same during the buckling process.

[0045] In this embodiment, when the first radius R1 is equal to the second radius R2, during the snapping process of the first snap plate 21 and the second snap plate 31 (or after the snapping of the first snap plate 21 and the second snap plate 31 is completed), the torque applied by the external force to the first center O1 and the second center O2 is equal, so as to avoid damage to one of the snap plates when the torques are unequal.

[0046] For example, such as Figure 3 The first central angle A1 is equal to the second central angle A2, and the first radius R1 is equal to the second radius R2. This facilitates the manufacturing of corner protectors for photovoltaic module packaging.

[0047] In other embodiments, the first central angle A1 is equal to the second central angle A2, and the first radius R1 is not equal to the second radius R2. Alternatively, the first central angle A1 is not equal to the second central angle A2, and the first radius R1 is equal to the second radius R2.

[0048] In some embodiments, continue to refer to Figure 2 As shown, the first connecting part 2 has a first connecting plate 22 connected to the first panel 12, and the packaging corner protector has a first connecting crease 23 located between the first connecting plate 22 and the first panel 12.

[0049] In this embodiment, by providing a first connecting crease 23 between the first connecting plate 22 and the first panel 12, it is convenient for the first connecting plate 22 and the first panel 12 to be folded together. During the folding process of the first connecting plate 22 and the first panel 12 along the first connecting crease 23, the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31 can be interlocked.

[0050] In some embodiments, the first connecting plate 22 has a first connecting side 24 that is opposite to the first connecting crease 23.

[0051] In this embodiment, the first connecting crease 23 and the first connecting side 24 can be parallel to each other.

[0052] In some embodiments, continue to refer to Figure 2 and Figure 3 As shown, the first buckle plate 21 has a first center O1.

[0053] In this embodiment, the first center O1 is the center of the arc-shaped outer contour of the first buckle plate 21.

[0054] In some embodiments, continue to refer to Figure 2 As shown, the second connecting part 3 has a second connecting plate 32 connected to the second panel 13, and the packaging corner protector has a second connecting crease 33 located between the second connecting plate 32 and the second panel 13.

[0055] In this embodiment, by providing a second connecting crease 33 between the second connecting plate 32 and the second panel 13, it is convenient for the second connecting plate 32 and the second panel 13 to be folded together. During the folding process of the second connecting plate 32 and the second panel 13 along the second connecting crease 33, the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31 can be snapped together.

[0056] In some embodiments, the second connecting plate 32 has a second connecting side 34 that is opposite to the second connecting crease 33.

[0057] In this embodiment, the second connecting crease 33 and the second connecting side 34 can be parallel to each other.

[0058] In some embodiments, continue to refer to Figure 2 and Figure 3 As shown, the second buckle plate 31 has a second center O2.

[0059] In this embodiment, the second center O2 is the center of the arc-shaped outer contour of the second buckle plate 31.

[0060] In some embodiments, the first center O1 is spaced apart from the first connecting side 24; and / or the second center O2 is spaced apart from the second connecting side 34.

[0061] In this embodiment, as Figure 3 The first center O1 and the first connecting side 24 are spaced apart from each other. Compared with the scheme where the first center O1 and the first connecting side 24 coincide (i.e., the first central angle A1 is not greater than 180°), the first central angle A1 can be increased (e.g., greater than 180°). Reducing the size of the first mating distance D1 makes it easier for the first snap-fit ​​plate 21 to be bent relative to the first connecting plate 22, facilitating the interlocking between the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31.

[0062] In this embodiment, as Figure 3 The second center O2 and the second connecting side 34 are spaced apart. Compared with the scheme where the second center O2 and the second connecting side 34 coincide (i.e., the second central angle A2 is not greater than 180°), the second central angle A2 can be increased (e.g., greater than 180°). Reducing the size of the second mating distance D3 makes it easier for the second snap plate 31 to be bent relative to the second connecting plate 32, facilitating the interlocking between the first snap plate 21 and the second snap plate 31.

[0063] In this embodiment, the first center O1 and the first connecting side 24 are spaced apart from each other, and the second center O2 and the second connecting side 34 are spaced apart from each other, which is conducive to the mutual snapping between the first snap plate 21 and the second snap plate 31.

[0064] In some embodiments, continue to refer to Figure 3 As shown, at least one of the first central angle A1 and the second central angle A2 is not less than 180°.

[0065] In this embodiment, the first central angle A1 and / or the second central angle A2 are not less than 180°. Compared with the scheme where "both the first central angle A1 and the second central angle A2 are less than 180°", this can prevent the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31 from separating after the snap-fit ​​is completed. As the central angle (e.g., the first central angle A1 and / or the second central angle A2) increases, the contact area between the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31 after they are snapped together increases, thereby improving the snap-fit ​​strength between them and making them less likely to separate.

[0066] In this embodiment, both the first central angle A1 and the second central angle A2 are greater than 180°, which improves the snapping strength between the first snap plate 21 and the second snap plate 31.

[0067] For example, the first central angle A1 can be between 180° and 250°, such as between 210° and 220°.

[0068] For example, the second central angle A2 can be between 180° and 250°, such as between 210° and 220°.

[0069] In some embodiments, continue to refer to Figure 2 As shown, the first connecting part 2 has a first snap-fit ​​25 formed between the first snap-fit ​​plate 21 and the first connecting plate 22.

[0070] In this embodiment, the outer contour of the first snap plate 21 is spaced apart from the first connecting plate 22 to form a first snap seam 25. That is, the first snap plate 21 and the first connecting plate 22 are formed by cutting the first snap seam 25 into the first connecting part 2.

[0071] In some embodiments, the first slot 25 has a first end 26 spaced apart from the first connecting side 24.

[0072] In this embodiment, one end of the first snap-fit ​​25 (i.e., the first end 26) is spaced apart from the first connecting side 24, and the other end of the first snap-fit ​​25 overlaps with the first connecting side 24, thereby facilitating the bending of the first snap-fit ​​plate 21 relative to the first connecting plate 22, so as to realize the snap-fit ​​of the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31.

[0073] In some embodiments, the first snap plate 21 has a first end 27 facing away from the first connecting side 24.

[0074] In this embodiment, the first end 27 is located on the side of the first buckle plate 21 near the first connecting crease 23.

[0075] In some embodiments, such as Figure 3 The first end 26 and the first connecting side 24 have a first mating distance D1, and the first end 27 and the first connecting side 24 have a first snapping distance D2.

[0076] In some embodiments, continue to refer to Figure 2 As shown, the second connecting part 3 has a second snap-fit ​​35 formed between the second snap-fit ​​plate 31 and the second connecting plate 32.

[0077] In this embodiment, the outer contour of the second snap-fit ​​plate 31 is spaced apart from the second connecting plate 32, thereby forming a second snap-fit ​​seam 35. That is, the second snap-fit ​​plate 31 and the second connecting plate 32 are formed by cutting the second snap-fit ​​seam 35 into the second connecting portion 3. In some embodiments, the second slot 35 has a second end 36 spaced apart from the second connecting side 34.

[0078] In this embodiment, one end of the second snap-fit ​​35 (i.e., the second end 36) is spaced apart from the second connecting side 34, and the other end of the second snap-fit ​​35 overlaps with the second connecting side 34, thereby facilitating the bending of the second snap-fit ​​plate 31 relative to the second connecting plate 32, so as to realize the mutual snap-fit ​​between the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31.

[0079] In some embodiments, the second snap plate 31 has a second end 37 that is opposite to the second connecting side 34.

[0080] In this embodiment, the second end 37 is located on the side of the second buckle plate 31 near the second connecting crease 33.

[0081] In some embodiments, such as Figure 3The second end 36 and the second connecting side 34 have a second mating distance D3, and the second end 37 and the second connecting side 34 have a second snapping distance D4.

[0082] In some embodiments, the first mating distance D1 is not greater than the first snapping distance D2; and / or the second mating distance D3 is not greater than the second snapping distance D4.

[0083] In this embodiment, the first end 27 protrudes towards the side opposite to the first connecting side 24 relative to the first end 26, that is, the first end 27 protrudes towards the side closer to the first connecting crease 23 relative to the first end 26. In other words, the distance between the first end 26 and the first connecting crease 23 is greater than the distance between the first end 27 and the first connecting crease 23. This creates a "P"-shaped latch structure between the first locking seam 25 and the first connecting side 24, making it difficult for the first latch plate 21 and the second latch plate 31 to detach after they are engaged.

[0084] In this embodiment, the second end 37 protrudes towards the side opposite to the second connecting side 34 relative to the second end 36, that is, the second end 37 protrudes towards the side closer to the second connecting crease 33 relative to the second end 36. In other words, the distance between the second end 36 and the second connecting crease 33 is greater than the distance between the second end 37 and the second connecting crease 33. This creates a "P"-shaped locking tongue structure between the second locking seam 35 and the second connecting side 34, making it difficult for the first locking plate 21 and the second locking plate 31 to detach after they are engaged.

[0085] For example, such as Figure 3 The first docking distance D1 is less than the first latching distance D2, and the second docking distance D3 is less than the second latching distance D4.

[0086] In some embodiments, continue to refer to Figure 1 and Figure 2 As shown, the main body 1 has at least one latch plate 4.

[0087] In this embodiment, the main body 1 may have one latch plate 4. The main body 1 may also have two latch plates 4.

[0088] In some embodiments, the latch plate 4 is disposed on at least one of the first panel 12 and the second panel 13.

[0089] In this embodiment, the main body 1 has a latch plate 4, which is disposed on the first panel 12 or the second panel 13. When installing the photovoltaic module packaging corner protectors, it is necessary to distinguish the installation direction of the first panel 12 and the second panel 13, that is, the latch plate 4 needs to correspond to the back of the frame 5. Reducing the number of latch plates 4 can reduce the manufacturing cost of the photovoltaic module packaging corner protectors and improve the structural strength of the photovoltaic module packaging corner protectors.

[0090] In this embodiment, the main body 1 has two latch plates 4, which are respectively disposed on the first panel 12 and the second panel 13. When installing the photovoltaic module packaging corner protectors, it is not necessary to distinguish the installation direction of the first panel 12 and the second panel 13; simply press the latch plate 4 corresponding to the back of the frame 5. This improves the installation efficiency of the photovoltaic module packaging corner protectors.

[0091] For example, such as Figure 1 and Figure 4 As shown, after the latch plate 4 is pressed, at least a portion of the latch plate 4 extends into the inside of the frame 5, which can prevent the photovoltaic module packaging corner protectors from separating and falling off from the frame 5. By using the pressing of the latch plate 4 to limit the positioning of the photovoltaic module packaging corner protectors, it can be applied to photovoltaic modules without a C-side frame 5, or photovoltaic modules with a narrow C-side frame 5.

[0092] In some embodiments, continue to refer to Figure 2 As shown, the main body 1 has a first latch plate 41, which is disposed on the first panel 12.

[0093] In some embodiments, the main body 1 has a first latch plate 41 and a second latch plate 42 disposed on the second panel 13.

[0094] In this embodiment, the first latch plate 41 and the second latch plate 42 are symmetrically arranged with respect to the side plate 11.

[0095] In some embodiments, the packaging corner protectors have a first body crease 14 located between the first panel 12 and the side panel 11.

[0096] In this embodiment, by providing a first main body crease 14 between the first panel 12 and the side panel 11, it is convenient for the first panel 12 and the side panel 11 to be folded together. After the first panel 12 and the side panel 11 are folded along the first main body crease 14, the first panel 12 and the side panel 11 are respectively attached to different surfaces of the frame 5.

[0097] In some embodiments, the first panel 12 has a first body side 16 connecting the first body crease 14 and the first connecting crease 23.

[0098] In this embodiment, the first connecting crease 23 and the first main body crease 14 correspond to the two right-angled sides of the first panel 12 (e.g., the first panel 12 of a right triangle), for example, the lengths of the first connecting crease 23 and the first main body crease 14 are equal. The first main body side 16 corresponds to the hypotenuse of the first panel 12 (e.g., the first panel 12 of a right triangle).

[0099] In some embodiments, the packaging corner protectors have a second body crease 15 located between the second panel 13 and the side panel 11.

[0100] In this embodiment, by providing a second main body fold 15 between the second panel 13 and the side panel 11, it is convenient for the second panel 13 and the side panel 11 to be folded together. After the second panel 13 and the side panel 11 are folded along the second main body fold 15, the second panel 13 and the side panel 11 are respectively attached to different surfaces of the frame 5.

[0101] In some embodiments, the second panel 13 has a second body side 17 that connects the second body crease 15 and the second connecting crease 33.

[0102] In this embodiment, the second connecting crease 33 and the second main body crease 15 correspond to the two right-angled sides of the second panel 13 (e.g., the second panel 13 of a right triangle), for example, the lengths of the second connecting crease 33 and the second main body crease 15 are equal. The second main body side 17 corresponds to the hypotenuse of the second panel 13 (e.g., the second panel 13 of a right triangle).

[0103] In some embodiments, in conjunction with reference Figure 2 and Figure 5 As shown, the first latch plate 41 has a first latch side 43 facing away from the first main body side 16, and / or the second latch plate 42 has a second latch side 44 facing away from the second main body side 17.

[0104] In this embodiment, the setting of the first tab side 43 can ensure that the first tab plate 41 extends into the inner side of the frame 5 along both sides of the first tab side 43, thereby improving the limiting strength of the first tab plate 41 for the photovoltaic module packaging corner protector and making it less likely for the photovoltaic module packaging corner protector to detach from the frame 5.

[0105] In this embodiment, the setting of the second latch side 44 can ensure that the second latch plate 42 extends into the inner side of the frame 5 along both sides of the second latch side 44, thereby improving the limiting strength of the second latch plate 42 for the photovoltaic module packaging corner protector and making it less likely for the photovoltaic module packaging corner protector to detach from the frame 5.

[0106] In some embodiments, the first latch side 43 is parallel to or intersects with the first body side 16, and / or the second latch side 44 is parallel to or intersects with the second body side 17.

[0107] In this embodiment, as Figure 5 The first tab side 43 and the first main body side 16 are parallel to each other, which can improve the stability of the photovoltaic module packaging corner protector after it is installed on the frame 5 compared to the intersecting scheme.

[0108] In this embodiment, as Figure 5 The second tab side 44 and the second main body side 17 are parallel to each other, which can improve the stability of the photovoltaic module packaging corner protector after it is installed on the frame 5 compared to the intersecting scheme.

[0109] In some embodiments, in conjunction with reference Figure 2 and Figure 5 As shown, the first latch plate 41 has two first latch connecting edges 45, which are located on opposite sides of the first latch side 43; and / or, the second latch plate 42 has two second latch connecting edges 46, which are located on opposite sides of the second latch side 44.

[0110] In this embodiment, two first latch connecting edges 45 are symmetrically arranged on opposite sides of the first latch side edge 43.

[0111] In this embodiment, two second latch connecting edges 46 are symmetrically arranged on opposite sides of the second latch side edge 44.

[0112] In some embodiments, the first latch connecting edge 45 intersects with the first latch side edge 43, and / or the second latch connecting edge 46 intersects with the second latch side edge 44.

[0113] In this embodiment, after the first latch connecting edge 45 intersects with the first latch side edge 43, an angle is formed between them. That is, the first latch plate 41 forms two angles along both sides of the first latch side edge 43. By using these two angles to extend into the inner side of the frame 5, the resistance encountered by the first latch plate 41 during the pressing process is reduced, and the pressing operation of the first latch plate 41 is smoother, facilitating the pressing and installation of the first latch plate 41. Furthermore, after the first latch plate 41 is pressed and installed, the aforementioned two angles (i.e., the angle between the first latch connecting edge 45 and the first latch side edge 43) can effectively prevent the photovoltaic module packaging corner protectors from detaching from the frame 5, thereby improving the limiting strength of the first latch plate 41 for the photovoltaic module packaging corner protectors.

[0114] In this embodiment, after the second latch connecting edge 46 intersects with the second latch side edge 44, an angle is formed between them. That is, the second latch plate 42 forms two angles along both sides of the second latch side edge 44. By using these two angles to extend into the inner side of the frame 5, the resistance encountered by the second latch plate 42 during the pressing process is reduced, and the pressing operation of the second latch plate 42 is smoother, facilitating the pressing and installation of the second latch plate 42. Furthermore, after the second latch plate 42 is pressed and installed, the aforementioned two angles (i.e., the angle between the second latch connecting edge 46 and the second latch side edge 44) can effectively prevent the photovoltaic module packaging corner protectors from detaching from the frame 5, thereby improving the limiting strength of the second latch plate 42 for the photovoltaic module packaging corner protectors.

[0115] For example, such as Figure 5 The included angles formed between the two first latch connecting edges 45 and the first latch side edge 43 are equal. For example, the included angle between the first latch connecting edge 45 and the first latch side edge 43 can be 90°, that is, the first latch connecting edge 45 and the first latch side edge 43 are perpendicular to each other.

[0116] For example, such as Figure 5 The included angles formed between the two connecting edges 46 of the second latch and the side edge 44 of the second latch are equal. For example, the included angle between the connecting edge 46 of the second latch and the side edge 44 of the second latch can be 90°, that is, the connecting edge 46 of the second latch and the side edge 44 of the second latch are perpendicular to each other.

[0117] In some embodiments, in conjunction with reference Figure 2 and Figure 5 As shown, the first latch plate 41 has a first latch support edge 47 corresponding to the first latch connecting edge 45, and the first latch support edge 47 connects the first latch connecting edge 45 and the first panel 12; and / or, the second latch plate 42 has a second latch support edge 48 corresponding to the second latch connecting edge 46, and the second latch support edge 48 connects the second latch connecting edge 46 and the second panel 13.

[0118] In this embodiment, by setting a first tab support edge 47 between the first tab connecting edge 45 and the first panel 12, the strength of the root of the first tab plate 41 can be improved, thereby increasing the limiting strength of the first tab plate 41 for the photovoltaic module packaging corner protector, making it less likely for the photovoltaic module packaging corner protector to detach from the frame 5.

[0119] In this embodiment, by setting a second tab support edge 48 between the second tab connecting edge 46 and the second panel 13, the strength of the root of the second tab plate 42 can be improved, thereby increasing the limiting strength of the second tab plate 42 for the photovoltaic module packaging corner protector, making it less likely for the photovoltaic module packaging corner protector to detach from the frame 5.

[0120] In some embodiments, the first latch connecting edge 45 intersects with the first latch supporting edge 47, and / or the second latch connecting edge 46 intersects with the second latch supporting edge 48.

[0121] In this embodiment, the first latch connecting edge 45 intersects with the first latch supporting edge 47. For example, the included angle between the first latch connecting edge 45 and the first latch supporting edge 47 is greater than 90°, which improves the strength of the root of the first latch plate 41.

[0122] In this embodiment, the second latch connecting edge 46 intersects with the second latch supporting edge 48. For example, the included angle between the second latch connecting edge 46 and the second latch supporting edge 48 is greater than 90°, which improves the strength of the root of the second latch plate 42.

[0123] In some embodiments, continue to refer to Figure 2 As shown, the main body 1 has a third main body side 18 and a fourth main body side 19, which are located on opposite sides of the side plate 11.

[0124] In some embodiments, the third main body side 18, the first connecting portion 2, and the second connecting portion 3 are located on the same side of the main body portion 1.

[0125] In this embodiment, the third main body side 18 is located between the first connecting plate 22 and the second connecting plate 32. When the size of the third main body side 18 increases, the size of the first connecting plate 22 and the second connecting plate 32 can be reduced.

[0126] In some embodiments, the length of the third body side 18 is not less than the length of the fourth body side 19.

[0127] In this embodiment, when the length of the third main body side 18 is greater than the length of the fourth main body side 19, the length of the first connecting plate 22 and the second connecting plate 32 can be shortened, which can save the material of the photovoltaic module packaging corner protector and reduce the weight.

[0128] For example, when the length of the third main body side 18 is equal to the length of the fourth main body side 19, the first connecting plate 22 and the second connecting plate 32 can better protect the side of the frame 5, thereby covering the corner of the frame 5.

[0129] For example, continue to refer to Figure 4As shown, the second panel 13 can be first attached to the back of the frame 5, and then the side panel 11 can be folded along the second main body crease 15 so that the side panel 11 is attached to the side of the frame 5. Next, the first panel 12 can be folded along the first main body crease 14 so that the first panel 12 is attached to the front of the frame 5. Then, the first connecting plate 22 can be folded along the first connecting crease 23, and the second connecting plate 32 can be folded along the second connecting crease 33. During the folding of the first connecting plate 22 and the second connecting plate 32, the first snap-fit ​​plate 21 and the second snap-fit ​​plate 31 can be controlled to snap together so that the second connecting plate 32 is attached to the side of the frame 5. Finally, by pressing the second latch plate 42, the second latch plate 42 can be inserted into the inside of the frame 5. At this point, the installation of the photovoltaic module packaging corner protectors onto the frame 5 is completed.
