An embodiment of the present application provides a corner protection structure, which can be used to protect the corners of photovoltaic modules to avoid contact and wear between two adjacent photovoltaic modules during transportation, thereby improving the transportation safety of the photovoltaic modules.

Referring to Fig. 1, a schematic diagram of the structure of a corner protection structure in an embodiment of the present application is shown in an unfolded state. Referring to Fig. 2, a schematic diagram of the structure of the corner protection structure shown in Fig. 1 is shown in a folded state.

As shown in Figures 1 and 2, the corner guard structure may specifically include: a base plate 10, the base plate 10 having an adjacent first side and a second side; a first side plate 11, a first top plate 12, a first guard plate 13 and a second guard plate 14 extending outward from the first side of the base plate 10 in sequence and foldable; and a second side plate 15, a second top plate 16, a third guard plate 17 and a fourth guard plate 18 extending outward from the second side of the base plate 10 in sequence and foldable, a first plug-in board 161 being provided on a side of the second top plate 16 away from the second side plate 15; wherein, when the first side plate 11, the first top plate 12, the first guard plate 13 and the second guard plate 14 are folded in sequence along the photovoltaic component, and the second side plate 15, the second top plate 16, the third guard plate 17 and the second guard plate 14 are folded in sequence along the photovoltaic component, the first plug-in board 161 is inserted between the first top plate 12 and the first guard plate 13, and the second guard plate 14 and the fourth guard plate 18 are respectively abutted against the side edges of the photovoltaic component.

In the embodiment of the present application, the corner protection structure can be used to protect the corner of the photovoltaic module. When the first side plate 11, the first top plate 12, the first guard plate 13 and the second guard plate 14 of the corner protection structure are folded in sequence along the photovoltaic module, and the second side plate 15, the second top plate 16, the third guard plate 17 and the fourth guard plate 18 are folded in sequence along the photovoltaic module, the first plug-in board 16 can be inserted between the first top plate 12 and the first guard plate 13, so that the first top plate 12 on the first side of the bottom plate 10 and the second top plate 16 on the second side can wrap and constrain each other, greatly improving the assembly tightness of the corner protection structure, so that the corner protection structure is not easy to fall from the photovoltaic module. Moreover, the second guard plate 14 and the fourth guard plate 18 can respectively abut against the two adjacent sides of the photovoltaic module to limit the photovoltaic module, further improving the packaging reliability of the corner protection structure for the photovoltaic module. In this way, it is possible to avoid the operation of reworking the corner of the photovoltaic module with the corner protection structure, greatly improving the packaging efficiency of the photovoltaic module and the transportation safety of the photovoltaic module.

In a specific application, when the corner protection structure is used to wrap the corner of the photovoltaic module, the bottom plate 10 can be attached to the bottom of the photovoltaic module, and the first side and the second side of the bottom plate 10 are respectively close to the two side edges adjacent to the corner of the photovoltaic module. The first side plate 11 can be attached to one of the side edges of the photovoltaic module, the second side plate 15 can be attached to the other side edge of the photovoltaic module, and the first top plate 12 and the second top plate 16 can be attached to the top of the photovoltaic module respectively, so as to achieve all-round wrapping of the corner of the photovoltaic module.

Moreover, the first guard plate 13 and the second guard plate 14 can extend between the first side plate 11 and one of the side edges of the photovoltaic assembly, and the end of the second guard plate 14 away from the first guard plate 13 can abut against the side edge of the photovoltaic assembly, so that the first guard plate 13 and the second guard plate 14 are not easy to slip out from between the first side plate 11 and the photovoltaic assembly, thereby improving the connection reliability between the corner guard structure and the photovoltaic assembly. Similarly, the third guard plate 17 and the fourth guard plate 18 can extend between the second side plate 15 and the other side edge of the photovoltaic assembly, and the end of the fourth guard plate 18 away from the third guard plate 17 can abut against the side edge of the photovoltaic assembly, so that the third guard plate 17 and the fourth guard plate 18 are not easy to slip out from between the second side plate 15 and the photovoltaic assembly, thereby improving the connection reliability between the corner guard structure and the photovoltaic assembly.

In the embodiment of the present application, during the process of wrapping the photovoltaic module with the corner protection structure, the first plug-in board 161 on the second top plate can be inserted between the first top plate 12 and the first protective plate 13, so that the first top plate 12 and the second top plate 16 can wrap and constrain each other, greatly improving the assembly tightness of the corner protection structure, making it difficult for the corner protection structure to fall off the photovoltaic module. In this way, not only can the packaging efficiency of the corner protection structure for packaging the photovoltaic module corner be improved. Moreover, during the transportation of the photovoltaic module, the corner protection structure can always be reliably connected to the corner of the photovoltaic module, thereby improving the transportation safety of the photovoltaic module.

In the embodiment of the present application, a second plug-in board 181 is further provided on the side of the fourth guard plate 18 away from the second side plate 15. As shown in FIG2 , when the first side plate 11, the first top plate 12, the first guard plate 13 and the second guard plate 14 are folded in sequence along the photovoltaic assembly, and the second side plate 15, the second top plate 16, the third guard plate 17 and the second guard plate 14 are folded in sequence along the photovoltaic assembly, the second plug-in board 181 can be inserted between the second guard plate 14 and the first side plate 11 to limit the second guard plate 14 and improve the reliability of the second guard plate 14 being clamped between the photovoltaic assembly and the first side plate 11, so that the corner guard structure can achieve overall constraint and a clamping and wrapping effect.

As shown in FIG1 , the second plug-in board 181 and the first plug-in board 161 are both rectangular plug-in boards, and the width of the first plug-in board 161 along the second side is greater than the width of the second plug-in board 181 along the second side. In a specific application, when the first plug-in board 161 is a rectangular plug-in board and the width of the first plug-in board 161 is greater than the width of the second plug-in board 181, the contact area between the first plug-in board 161 and the first top plate 12 and the top of the photovoltaic assembly can be made larger. In this way, the first plug-in board 161 can be made less likely to fall out from between the photovoltaic assembly and the first top plate 12, further improving the reliability of the corner protection structure wrapping the photovoltaic assembly corner protection. When the second plug-in board 181 is a rectangular plug-in board and the width of the second plug-in board 181 is less than the first plug-in board 161, both the reliable limiting of the fourth guard plate 18 can be achieved and the structure of the entire corner protection structure can be made more compact.

As shown in FIG1 , a groove 162 is provided at the connection between the second top plate 16 and the first plug-in board 161. The setting of the groove 162 facilitates the first plug-in board 161 to be fully inserted into the gap between the first top plate 12 and the first guard plate 13, thereby avoiding interference between the first plug-in board 161 and the first top plate 12 or the first guard plate 13, thereby improving the plug-in efficiency of the first plug-in board 161, and thereby improving the assembly efficiency of the entire corner protection structure.

Optionally, the groove 162 is a triangular groove 162. By setting the groove 162 as a triangular groove 162, not only can the shape of the groove 162 be simpler and more regular, which is convenient for processing, but also the groove 162 can effectively avoid the first top plate 12 and the first guard plate 13, avoiding the second top plate 16 from interfering with the first top plate 12 and the first guard plate 13, thereby improving the assembly safety of the corner protection structure.

It should be noted that, in practical applications, the groove 162 can also be set to a rectangular shape, an arc shape, or other shapes according to actual needs. The embodiment of the present application does not specifically limit the shape of the groove 162.

In a specific application, when the first side panel 11, the first top panel 12, the first guard panel 13 and the second guard panel 14 are folded in sequence, the first side panel 11 is perpendicular to the bottom panel 10, so that the first side panel 11 fits with the side of the photovoltaic module, and the first top panel 12 is parallel to the bottom panel 10, so that the first top panel 12 fits with the top of the photovoltaic module. The first guard panel 13 can be folded toward the first side panel 11 to form a folding force toward the side of the photovoltaic module, and the second guard panel 14 can be folded in a direction away from the first side panel 11 to form a folding force away from the side of the photovoltaic module. In practical applications, the folding forces formed by the first guard panel 13 and the second guard panel 14 in opposite directions can reliably clamp the first guard panel 13 and the second guard panel 14 between the side of the photovoltaic module and the first side panel 11, preventing the first guard panel 13 and the second guard panel 14 from coming out from between the side of the photovoltaic module and the first side panel 11, and further improving the connection reliability between the corner guard structure and the photovoltaic module.

Similarly, when the second side panel 15, the second top panel 16, the third guard panel 17 and the fourth guard panel 18 are folded in sequence, the second side panel 15 is perpendicular to the bottom panel 10, so that the second side panel 15 fits with the side of the photovoltaic module, and the second top panel is parallel to the bottom panel 10, so that the second top panel fits with the top of the photovoltaic module. The third guard panel 17 can be folded toward the second side panel 15 to form a folding force toward the side of the photovoltaic module, and the fourth guard panel 18 can be folded in a direction away from the second side panel 15 to form a folding force away from the side of the photovoltaic module. In actual applications, the folding forces formed by the third guard panel 17 and the fourth guard panel 18 in opposite directions can reliably clamp the third guard panel 17 and the fourth guard panel 18 between the side of the photovoltaic module and the second side panel 15, preventing the third guard panel 17 and the fourth guard panel 18 from coming out from between the side of the photovoltaic module and the second side panel 15, further improving the connection reliability between the corner guard structure and the photovoltaic module.

In some optional embodiments of the present application, the angle between the first guard plate 13 and the first top plate 12 is less than 90 degrees, so that the first guard plate 13 can be folded toward the first side plate 11 to form a folding force toward the side of the photovoltaic module. The angle between the third guard plate 17 and the second top plate 16 is less than 90 degrees, so that the third guard plate 17 can be folded toward the second side plate 15 to form a folding force toward the side of the photovoltaic module.

For example, the angle between the first guard plate 13 and the first top plate 12, and the angle between the third guard plate 17 and the second top plate may include but are not limited to any one of 30 degrees, 50 degrees, 72 degrees or 85 degrees, and the embodiments of the present application do not make specific limitations on this.

And/or, the angle between the second guard plate 14 and the bottom plate 10 is less than or equal to 90 degrees, so that the first guard plate 13 can be folded in a direction away from the first side plate 11, forming a folding force away from the side of the photovoltaic module. The angle between the fourth guard plate 18 and the bottom plate 10 is less than or equal to 90 degrees, so that the third guard plate 17 can be folded in a direction away from the second side plate 15, forming a folding force away from the side of the photovoltaic module.

In practical applications, when the second guard plate 14 is folded away from the first side plate 11, and the angle between the second guard plate 14 and the bottom plate 10 is less than or equal to 90, it is convenient for the second guard plate 14 and the first guard plate 13 to form a clamping angle, and it is also convenient for the second guard plate 14 to abut against the back glass of the photovoltaic module, so as to further improve the connection reliability between the corner guard structure and the photovoltaic module. Similarly, when the fourth guard plate 18 is folded away from the second side plate 15, and the angle between the fourth guard plate 18 and the bottom plate 10 is less than or equal to 90, it is convenient for the fourth guard plate 18 and the third guard plate 17 to form a clamping angle, and it is also convenient for the fourth guard plate 18 to abut against the back glass of the photovoltaic module, so as to further improve the connection reliability between the corner guard structure and the photovoltaic module.

For example, the angle between the second guard plate 14 and the base plate 10, and the angle between the fourth guard plate 18 and the base plate 10 may include but are not limited to any one of 30 degrees, 50 degrees, 72 degrees, 85 degrees or 90 degrees, and the embodiments of the present application do not specifically limit this.

As shown in FIG1 , the connection between the first side panel 11, the second side panel 15 and the bottom panel 10 is provided with a chamfer 19. The chamfer 19 can be used to avoid the defect that the connection between the first side panel 11, the second side panel 15 and the bottom panel 10 cannot be flat when the first side panel 11 and the second side panel 15 are folded to a position perpendicular to the bottom panel 10, improve the folding quality of the first side panel 11 and the second side panel 15, so that the first side panel 11 and the second side panel 15 can better fit the side edge of the photovoltaic module, and further improve the connection reliability between the corner protection structure and the photovoltaic module.

In some optional embodiments of the present application, the bottom plate 10, the first side plate 11, the first top plate 12, the first

The first guard plate 13, the second guard plate 14, the second side plate 15, the second top plate 16, the third guard plate 17 and the fourth guard plate 18 can be one of kraft paperboard, corrugated paperboard and polyvinyl chloride board. The embodiment of the present application does not make any specific limitation on the specific corner protection structure.

In actual applications, the bottom plate 10, the first side plate 11, the first top plate 12, the first guard plate 13, the second guard plate 14, the second side plate 15 and the second top plate 16 can be processed by an integrated molding process, and folds can be set between the bottom plate 10 and the first side plate 11, between the first side plate 11 and the first top plate 12, between the first top plate 12 and the first guard plate 13, between the first guard plate 13 and the second guard plate 14, between the bottom plate 10 and the second side plate 15, between the second side plate 15 and the second top plate 16, between the third guard plate 17 and the second top plate 16, and between the fourth guard plate 18 and the third guard plate 17, so as to facilitate the folding of the corner protection structure.

The following is an example of the folding of the corner protection structure described in the embodiment of the present application:

First, the second side panel 15 is folded to be perpendicular to the bottom panel 10, and the second top panel 16 is folded to be perpendicular to the second side panel 15. After the second top panel 16 is folded, the second top panel 16 can be parallel to the bottom panel 10. The third guard panel 17 is folded toward the second side panel 15 so that the angle between the third guard panel 17 and the second top panel is less than 90°, and then the fourth guard panel 18 is folded away from the second side panel 15 so that the angle between the fourth guard panel 18 and the bottom panel 10 is less than or equal to 90°.

Then, the first side plate 11 is folded to be perpendicular to the bottom plate 10, and the first top plate 12 is folded to be perpendicular to the first side plate 11, so that the first plug board 161 is located between the top of the photovoltaic module and the first top plate 12. The first guard plate 13 is folded toward the first side plate 11, so that the angle between the first guard plate 13 and the first top plate 12 is less than 90°, and then the second guard plate 14 is folded away from the first side plate 11, so that the angle between the second guard plate 14 and the bottom plate 10 is less than or equal to 90°.

Because the first plug-in board 161 on the second top plate 16 is inserted into the angle between the top of the photovoltaic module and the first top plate 12, the first top plate 12 and the second top plate 16 can wrap and restrain each other, greatly improving the assembly tightness of the corner protection structure and making it difficult for the corner protection structure to fall off the photovoltaic module.

In summary, the corner protection structure described in the embodiment of the present application can at least include the following advantages:

In the embodiment of the present application, the corner protection structure can be used to protect the corners of the photovoltaic assembly. When the first side plate, the first top plate, the first guard plate and the second guard plate of the corner protection structure are folded in sequence along the photovoltaic assembly, and the second side plate, the second top plate, the third guard plate and the fourth guard plate are folded in sequence along the photovoltaic assembly, the first plug-in board can be inserted between the first top plate and the first guard plate, so that the first top plate on the first side of the bottom plate and the second top plate on the second side can wrap and constrain each other, greatly improving the assembly tightness of the corner protection structure, so that the corner protection structure is not easy to fall from the photovoltaic assembly. Moreover, the second guard plate and the fourth guard plate can respectively abut against the two adjacent side edges of the photovoltaic assembly to limit the photovoltaic assembly, further improving the packaging reliability of the corner protection structure for the photovoltaic assembly. In this way, the operation of reworking the corner of the photovoltaic assembly with the corner protection structure can be avoided, greatly improving the packaging efficiency of the photovoltaic assembly and the transportation safety of the photovoltaic assembly.

An embodiment of the present application also provides a packaging component, which may specifically include an anti-falling strip and the corner protection structure described in any of the above embodiments; wherein one of the corner protection structures is used to be packaged at the corner of a photovoltaic component, and the anti-falling strip is bonded to the multiple corner protection structures.

Specifically, the anti-falling strip can be used in conjunction with the corner protection structure described in the aforementioned embodiment.

Referring to FIG3 , a schematic diagram of the structure of an anti-falling strip according to an embodiment of the present application is shown, and referring to FIG4 , a schematic diagram of the decomposed structure of the anti-falling strip shown in FIG3 is shown. Referring to FIG5 , a schematic diagram of the anti-falling strip shown in FIG4 being bonded to the corner protection structure is shown, and referring to FIG6 , an enlarged schematic diagram of position A in FIG5 is shown. As shown in FIG3 and FIG4 , the anti-falling strip 200 may specifically include: a cardboard layer 20, an adhesive layer 21, and an adhesive paper layer 22 arranged in sequence; wherein the adhesive layer 21 is bonded to the cardboard layer 20 and the adhesive paper layer 22, respectively; the adhesive paper layer 22 is provided with an adhesive surface on the side away from the adhesive layer 21, and the adhesive surface is used to bond to the corner protection structure 100.

As shown in FIG5 , the corner protection structure 100 can be respectively installed at the four corners of the photovoltaic module 300. When multiple photovoltaic modules 300 are placed vertically and closely together, the anti-falling strip 200 can be connected to the corner protection of multiple photovoltaic modules 300, and the two ends of the anti-falling strip 200 are respectively connected to the two outermost photovoltaic modules.

300 , so as to connect the multiple photovoltaic modules 300 into a whole, prevent the photovoltaic modules 300 from tilting or falling outward, and improve the transportation safety of the photovoltaic modules 300 .

In the embodiment of the present application, since the anti-falling strip 200 may include a paperboard layer 20, the structure of the paperboard layer 20 is relatively stable and not easily deformed. When the anti-falling strip 200 is bonded to the corner protection structure 100 of multiple photovoltaic modules 300, even if the positions of the photovoltaic modules 300 are changed due to external forces in scenarios such as bumpy roads, the photovoltaic modules 300 can still be reliably connected together under the restraint of the paperboard layer 20, and are not easily tilted or overturned, further improving the transportation safety of the photovoltaic modules 300.

In some optional embodiments of the application, a plurality of folds 23 are provided on the paperboard layer 20 and are spaced apart along the length direction, and the extension direction of the folds 23 is parallel to the width direction of the paperboard layer 20; the gap between two adjacent folds 23 is adapted to the thickness of the photovoltaic module 300, and the greater the thickness of the photovoltaic module 300, the greater the gap between two adjacent folds 23.

As shown in FIG. 6 , the position of the fold 23 may be aligned with the gap between the photovoltaic components 300 , the number of the fold 23 may be one less than the number of the photovoltaic components 300 , and the fold 23 may be used to locate the position of the photovoltaic component 300 .

Referring to FIG7 , a connection structure diagram of the corner protection structure and the anti-falling strip is shown when the photovoltaic module needs to be peeled off, and referring to FIG8 , an enlarged structural schematic diagram of the B position in FIG7 is shown. As shown in FIG7 and FIG8 , in the process of peeling off the photovoltaic module 300, the anti-falling strip 200 can be torn off along the fold 23 of the anti-falling strip 200 to achieve accurate peeling of the photovoltaic module 300. In this way, the phenomenon that the photovoltaic module 300 that does not need to be peeled off falls over due to the low tearing accuracy of the anti-falling strip 200 during the peeling process of the photovoltaic module 300 can be avoided, and the peeling safety of the photovoltaic module 300 is improved, so as to further improve the use safety of the photovoltaic module 300.

For example, when only one photovoltaic module 300 needs to be peeled off, the anti-falling strip 200 corresponding to the photovoltaic module 300 can be torn off along the fold 23 of the anti-falling strip 200 to release the connection between the anti-falling strip 200 and the corner protection structure 100 of the photovoltaic module 300, so as to facilitate the removal of the photovoltaic module 300 from the pallet. In this way, the remaining photovoltaic modules 300 that do not need to be peeled off can still be connected into a whole under the restraint of the anti-falling strip 200, avoiding the phenomenon of the photovoltaic modules 300 that do not need to be peeled off from falling, and improving the peeling safety of the photovoltaic modules 300.

Specifically, the paperboard layer 20 can be cardboard, corrugated cardboard, etc. The gram weight of the paperboard layer 20 is ≥ 200g/ ^m2 , so that the paperboard layer 20 meets the bursting strength under strong tensile force. The paperboard layer 20 can be processed with segmented horizontal lines according to the width of the photovoltaic module 300 to facilitate the later disassembly operation. The adhesive layer 21 is double-sided adhesive, the lower adhesive surface 212 is bonded to the paperboard layer 20, and the upper adhesive surface 211 is bonded to the adhesive paper layer 22. When in use, tear off the adhesive paper layer 22 and stick it to the position of the corner protection structure 100 of the photovoltaic module 300 to achieve the separation of the photovoltaic module 300.
