Description

Technical Field

[0001] This invention relates to the field of packaging structure technology, and more specifically, to a packaging structure for photovoltaic modules. Background Technology

[0002] Currently, to prevent BIPV (Building Integrated Photovoltaics) back-frame modules from tipping over during transportation, slots are typically used to insert the ends of the photovoltaic back-frame modules into the slots for transport.

[0003] However, in the existing transportation method, considering the self-weight of the packaging structure, the slots are only set at the ends. The bottom of the slots is higher than the bottom pallet. This means that during transportation, the bottom edge of the photovoltaic back frame module cannot contact the bottom pallet to bear the force. As a result, the photovoltaic back frame module is subjected to uneven force during transportation and is prone to collision and damage due to transportation bumps. Summary of the Invention

[0004] The main objective of this invention is to provide a packaging structure for photovoltaic modules to solve the technical problem of uneven stress on photovoltaic modules during transportation in the prior art.

[0005] To achieve the above objectives, the present invention provides a packaging structure for a photovoltaic module, comprising:

[0006] Base;

[0007] The first positioning component and the second positioning component are both mounted on the base.

The first positioning groove and the second positioning groove are arranged opposite to each other and form a positioning space for accommodating the photovoltaic module.

[0008] A filling component is disposed on the base and located between the first positioning component and the second positioning component. The bottom of the first positioning groove and the bottom of the second positioning groove are both flush with the side of the filling component away from the base.

[0017] Furthermore, the packaging structure also includes:

[0018] The third positioning component is located between the first positioning component and the second positioning component; the third positioning component is provided with a third positioning groove, the opening of the third positioning groove is oriented toward the positioning space, so that at least part of the photovoltaic module is inserted into the third positioning groove.

[0019] Furthermore, both the first positioning component and the second positioning component are made of foamed polypropylene; and / or,

[0020] The third positioning component is made of ethylene-vinyl acetate copolymer.

[0021] Furthermore, the packaging structure also includes a lifting bracket, which is disposed between the first positioning component and the second positioning component. The lifting bracket is arranged around the positioning space and spaced apart from and opposite to the base; the side of the lifting bracket near the base is used to contact the edge of the photovoltaic module.

[0022] Wherein, along the extending direction of the first positioning component, the width of the hoisting bracket is greater than or equal to the width of the first positioning component; and / or,

[0023] The hoisting support includes interconnected frame members and reinforcing members. The frame members have a central opening, and the reinforcing members are disposed within the opening and extend along the extension direction of the first positioning component; and / or,

[0024] There are two hoisting brackets, which are located on both sides of the third positioning component and are in contact with the third positioning component.

[0025] Furthermore, the first positioning component includes a plurality of first positioning protrusions arranged sequentially at intervals, with a first positioning groove formed between each first positioning protrusion; the first positioning component also includes a first connecting hole and a second connecting hole, both for connecting to the base, the first connecting hole being disposed on a first positioning protrusion located at one end of the first positioning component; the second connecting hole being disposed on a first positioning protrusion located in the middle of the first positioning component; and / or,

[0026] The second positioning component includes a plurality of second positioning protrusions arranged sequentially at intervals, with a second positioning groove formed between each second positioning protrusion; the second positioning component also includes a third connecting hole and a fourth connecting hole, both of which are used to connect with the base, the third connecting hole being disposed on the second positioning protrusion located at the end of the second positioning component; the fourth connecting hole being disposed on the second positioning protrusion located in the middle of the second positioning component.

[0027] Furthermore, the packaging structure also includes a first enclosure component and a second enclosure component;

[0028] The first enclosure component is located on the side of the first positioning component away from the positioning space and is mounted on the base; the first enclosure component includes a first frame portion and a first reinforcing portion connected to each other, the first frame portion forming a rectangular structure, and the first reinforcing portion being located at the diagonal of the rectangular structure; and / or,

[0030] Furthermore, the packaging structure also includes:

[0031] The outer cover and outer packing straps form an accommodating space.

[0035] By applying the technical solution of this invention, photovoltaic modules can be positioned and fixed using a first positioning component and a second positioning component, preventing them from tipping over or colliding during transportation. However, because the first positioning groove of the first positioning component and the second positioning groove of the second positioning component are both at a certain height relative to the base, the bottom edge of the photovoltaic module cannot contact the base when positioned and fixed using these components. This embodiment addresses this by using a filling component to fill the gap between the bottom edge of the photovoltaic module and the base, thus providing support for the bottom edge. Furthermore, the size of the filling component ensures sufficient contact area between the photovoltaic module and the base, resulting in more stable support and more even force distribution during transportation, thereby reducing collisions caused by transportation bumps. Therefore, the technical solution of this invention solves the problem of uneven force distribution on photovoltaic modules during transportation in the prior art. Attached Figure Description

[0054] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0055] like Figures 1 to 6As shown, an embodiment of the present invention provides a packaging structure for a photovoltaic module. The packaging structure includes a base 10, a first positioning component 21, and a second positioning component 22. Both the first positioning component 21 and the second positioning component 22 are disposed on the base 10. The first positioning component 21 has a first positioning groove 211, and the second positioning component 22 has a second positioning groove. The first positioning groove 211 and the second positioning groove are arranged opposite to each other and form a positioning space for accommodating the photovoltaic module 70. The packaging structure also includes a filling component 30, which is disposed on the base 10 and located between the first positioning component 21 and the second positioning component 22. The bottom of the first positioning groove 211 and the bottom of the second positioning groove are both flush with the side of the filling component 30 away from the base 10. The sum of the distance between the filling component 30 and the first positioning component 21 and the distance between the filling component 30 and the second positioning component 22 is greater than or equal to 0 cm and less than or equal to 10 cm.

[0056] The photovoltaic module packaging structure provided in the embodiments of the present invention can position and fix the photovoltaic module 70 using the first positioning component 21 and the second positioning component 22, preventing the photovoltaic module 70 from tipping over or colliding during transportation. However, because the first positioning groove 211 of the first positioning component 21 has a certain height relative to the base 10, and the second positioning groove of the second positioning component 22 also has a certain height relative to the base 10, the bottom edge of the photovoltaic module 70 cannot contact the base 10 when the photovoltaic module 70 is positioned and fixed using the first positioning component 21 and the second positioning component 22. This embodiment fills the gap between the bottom edge of the photovoltaic module 70 and the base 10 using the filling component 30, thereby providing support for the bottom edge of the photovoltaic module 70. Furthermore, the size of the filling component 30 ensures a sufficient contact area between the photovoltaic module 70 and the base 10, making the support for the photovoltaic module 70 more stable and the force on the photovoltaic module 70 more even during transportation, thus reducing collisions caused by transportation bumps. Therefore, the packaging structure of the photovoltaic module provided in this embodiment can solve the technical problem of uneven stress on the photovoltaic module during transportation in the prior art.

[0057] Specifically, photovoltaic module 70 is a BIPV (Building Integrated Photovoltaics) photovoltaic module. More specifically, photovoltaic module 70 is a back-frame module without A-side and B-side, i.e., only a C-side back-frame module. Here, A-side refers to the top side of the solar panel of the photovoltaic module that receives sunlight, B-side refers to the side side of the solar panel, and C-side refers to the bottom side. Because BIPV photovoltaic modules differ from conventional photovoltaic modules in structure and packaging / transportation methods, the packaging structure used in this solution provides better protection for BIPV photovoltaic modules during transportation, taking into account their unique characteristics.

[0058] Specifically, considering the error during assembly, in order to improve the ease of installation of the filling component 30, the sum of the distance between the filling component 30 and the first positioning component 21 and the distance between the filling component 30 and the second positioning component 22 is greater than or equal to 5cm and less than or equal to 10cm.

[0059] Specifically, the filling component 30 includes a filling part 31 and a wear-resistant part 32, with the wear-resistant part 32 disposed on the side of the filling part 31 away from the base 10. Along the direction from the first positioning component 21 to the second positioning component 22, the difference between the length of the wear-resistant part 32 and the length of the filling part 31 is greater than or equal to 0 cm and less than or equal to 10 cm. This structural arrangement allows the filling part 31 to fill the gap between the bottom edge of the photovoltaic module 70 and the base 10, thus providing support for the bottom edge of the photovoltaic module 70. Simultaneously, the wear-resistant part 32 prevents direct contact and friction between the photovoltaic module 70 and the filling part 31, preventing scratches on the photovoltaic module 70. Furthermore, ensuring that the difference between the length of the wear-resistant part 32 and the length of the filling part 31 is greater than or equal to 0 cm and less than or equal to 10 cm increases the contact area between the photovoltaic module 70 and the base 10 while allowing for a certain assembly error margin, resulting in more stable support for the photovoltaic module 70 and more even stress distribution during transportation.

[0060] Specifically, considering the error during assembly, in order to improve the ease of installation of the wear-resistant part 32 and the filling part 31 between the first positioning component 21 and the second positioning component 22, the difference between the length of the wear-resistant part 32 and the length of the filling part 31 is greater than or equal to 5cm and less than or equal to 10cm.

[0061] Specifically, the filling component 30 includes a filling portion 31 and a wear-resistant portion 32, with the wear-resistant portion 32 disposed on the side of the filling portion 31 away from the base 10. The thickness of the wear-resistant portion 32 is greater than or equal to 2 mm and less than or equal to 5 mm. Specifically, the thickness of the wear-resistant portion 32 is 3 mm. This structural arrangement allows the filling portion 31 to fill the gap between the bottom edge of the photovoltaic module 70 and the base 10, thus providing support for the bottom edge of the photovoltaic module 70. Simultaneously, the wear-resistant portion 32 prevents direct contact and friction between the photovoltaic module 70 and the filling portion 31, thereby preventing scratches on the photovoltaic module 70. Furthermore, the thickness of the wear-resistant portion 32 being greater than or equal to 2 mm and less than or equal to 5 mm ensures its wear resistance, extends its service life, and reduces the weight of the filling component 30, facilitating transportation.

[0062] Specifically, the filling component 30 includes a filling portion 31 and a wear-resistant portion 32, with the wear-resistant portion 32 disposed on the side of the filling portion 31 away from the base 10. The thickness of the filling portion 31 is greater than or equal to 10 mm and less than or equal to 15 mm. Specifically, the thickness of the filling portion 31 is 10 mm. This structural arrangement allows the filling portion 31 to fill the gap between the bottom edge of the photovoltaic module 70 and the base 10, thus providing support for the bottom edge of the photovoltaic module 70. Simultaneously, the wear-resistant portion 32 prevents direct contact and friction between the photovoltaic module 70 and the filling portion 31, thereby preventing scratches on the photovoltaic module 70. Furthermore, ensuring the thickness of the filling portion 31 is greater than or equal to 10 mm and less than or equal to 15 mm effectively fills the gap between the bottom edge of the photovoltaic module 70 and the base 10 while avoiding excessive thickness that would increase the weight of the packaging structure, thus ensuring the economic efficiency of the packaging structure.

[0063] Specifically, the filling component 30 includes a filling part 31 and a wear-resistant part 32, with the wear-resistant part 32 disposed on the side of the filling part 31 away from the base 10. The filling part 31 is made of a rigid material, specifically wood. This structural arrangement allows the rigid filling part 31 to provide stable support to the bottom side of the photovoltaic module 70, ensuring that the uniformity of stress on the photovoltaic module 70 is not affected by bumps during transportation.

[0064] Specifically, in order to ensure uniform stress on the bottom edge of the photovoltaic module 70, the filling part 31 is a plate-shaped structure.

[0065] Specifically, the filling component 30 includes a filling portion 31 and a wear-resistant portion 32, with the wear-resistant portion 32 disposed on the side of the filling portion 31 away from the base 10. The wear-resistant portion 32 is made of corrugated paper or pearl cotton. This structural arrangement allows the wear-resistant portion 32, made of corrugated paper or pearl cotton, to contact the photovoltaic module 70, thereby preventing the photovoltaic module 70 from being scratched by direct contact with the rigid filling portion 31.

[0066] In this embodiment, the packaging structure further includes a third positioning component 23, which is located between the first positioning component 21 and the second positioning component 22. The third positioning component 23 has a third positioning groove, the opening of which faces the positioning space, so that at least a portion of the photovoltaic module 70 is inserted into the third positioning groove. This structural arrangement enhances the stability of the photovoltaic module 70 during transportation, reducing the risk of bending or collision.

[0067] Specifically, in order to further enhance the overall integrity of the packaging structure, the third positioning component 23 is positioned opposite to the filling component 30.

[0068] Specifically, both the first positioning component 21 and the second positioning component 22 are made of expanded polypropylene (EPP). This structural design reduces the overall weight of the packaging structure due to the lower weight of EPP, thus facilitating transportation. Simultaneously, EPP possesses good cushioning properties; by positioning the photovoltaic module 70 using the EPP-based first and second positioning components 21 and 22, the photovoltaic module 70 can be better protected, providing excellent cushioning against vibrations during transportation.

[0069] Specifically, the third positioning component 23 is made of ethylene-vinyl acetate copolymer (EVA). This structural design reduces the overall weight of the packaging structure due to the relatively light weight of EVA, thus facilitating transportation. Furthermore, ethylene-vinyl acetate copolymer (EVA) possesses good waterproof, corrosion-resistant, and vibration-damping properties. Positioning the photovoltaic module 70 using the EVA-based third positioning component 23 better protects the photovoltaic module 70 and prevents vibration during transportation.

[0070] In this embodiment, the packaging structure further includes a lifting bracket 40, which is disposed between the first positioning component 21 and the second positioning component 22. The lifting bracket 40 is arranged around the positioning space and spaced apart from and opposite to the base 10. The side of the lifting bracket 40 closest to the base 10 is used to contact the edge of the photovoltaic module 70. Along the extending direction of the first positioning component 21, the width of the lifting bracket 40 is greater than or equal to the width of the first positioning component 21. This structural arrangement protects the top edge of the photovoltaic module 70, and the fact that the width of the lifting bracket 40 is greater than or equal to the width of the first positioning component 21 ensures that pressure is not transmitted to the photovoltaic module 70 when the side of the packaging structure is subjected to pressure, thereby reducing the risk of damage to the photovoltaic module 70.

[0071] Specifically, the packaging structure also includes a lifting bracket 40, which is positioned between the first positioning component 21 and the second positioning component 22. The lifting bracket 40 is arranged around the positioning space and spaced apart from and opposite to the base 10. The side of the lifting bracket 40 closest to the base 10 is used to contact the edge of the photovoltaic module 70. The lifting bracket 40 includes a frame member 41 and a reinforcing member 42 connected to each other. The frame member 41 has a cutout in the middle, and the reinforcing member 42 is disposed within the cutout and extends along the extension direction of the first positioning component 21. This structural arrangement protects the top edge of the photovoltaic module 70 while reducing the weight of the lifting bracket 40, preventing it from being too heavy and causing pressure on the photovoltaic module 70. Furthermore, the reinforcing member 42 effectively enhances the overall stability of the lifting bracket 40 structure, further improving the overall structural strength of the packaging structure.

[0072] Specifically, the packaging structure also includes a lifting bracket 40, which is positioned between the first positioning component 21 and the second positioning component 22. The lifting bracket 40 is arranged around the positioning space and spaced apart from and opposite to the base 10. The side of the lifting bracket 40 closest to the base 10 is used to contact the edge of the photovoltaic module 70. There are two lifting brackets 40, located on either side of the third positioning component 23 and both in contact with it. This structural arrangement protects the top edge of the photovoltaic module 70 by providing two lifting brackets 40, preventing interference from the third positioning component 23 in the contact between the lifting bracket 40 and the photovoltaic module 70.

[0073] Specifically, the first positioning component 21 includes a plurality of first positioning protrusions 212 arranged sequentially at intervals, with a first positioning groove 211 formed between each first positioning protrusion 212; the first positioning component 21 also includes a first connecting hole 213 and a second connecting hole 214, both of which are used to connect to the base 10. The first connecting hole 213 is located on the first positioning protrusion 212 at the end of the first positioning component 21; the second connecting hole 214 is located on the first positioning protrusion 212 in the middle of the first positioning component 21. With this structural arrangement, multiple photovoltaic modules 70 can be positioned by the first positioning protrusions 212 and the first positioning grooves 211, avoiding collisions between the multiple photovoltaic modules 70. At the same time, the arrangement of the first connecting hole 213 and the second connecting hole 214 ensures a stable connection between the first positioning component 21 and the base 10, thereby stabilizing the position of the first positioning component 21 and preventing displacement of the first positioning component 21 from affecting the positioning of the photovoltaic modules 70.

[0074] Specifically, the first positioning component 21 includes a first upper positioning member 216 and a first lower positioning member 217. The positioning grooves of the first upper positioning member 216 and the first lower positioning member 217 are arranged opposite to each other and surround the positioning space. The first upper positioning member 216 and the first lower positioning member 217 are used to position the top and bottom of the photovoltaic module 70, respectively. This structural arrangement can better improve the positioning stability of the photovoltaic module 70 and reduce the risk of positioning failure.

[0075] Specifically, in order to facilitate connection with the base 10, the first connecting hole 213 and the second connecting hole 214 are both provided on the first lower positioning member 217.

[0076] Specifically, the second positioning component 22 includes a plurality of second positioning protrusions arranged at intervals, with second positioning grooves formed between each second positioning protrusion. The second positioning component 22 also includes a third connecting hole and a fourth connecting hole, both used for connection to the base 10. The third connecting hole is located on the second positioning protrusion at one end of the second positioning component 22; the fourth connecting hole is located on the second positioning protrusion in the middle of the second positioning component 22. This structural arrangement allows for the positioning of multiple photovoltaic modules 70 via the second positioning protrusions and second positioning grooves, preventing collisions between the photovoltaic modules 70. Simultaneously, the third and fourth connecting holes ensure a stable connection between the second positioning component 22 and the base 10, thereby stabilizing the position of the second positioning component 22 and preventing displacement of the second positioning component 22 from affecting the positioning of the photovoltaic modules 70.

[0077] Specifically, the second positioning component 22 includes a second upper positioning member 222 and a second lower positioning member 223. The positioning grooves of the second upper positioning member 222 and the second lower positioning member 223 are arranged opposite to each other and surround the positioning space. The second upper positioning member 222 and the second lower positioning member 223 are used to position the top and bottom of the photovoltaic module 70, respectively. This structural arrangement can better improve the positioning stability of the photovoltaic module 70 and reduce the risk of positioning failure.

[0078] Specifically, in order to facilitate connection with the base 10, the third and fourth connecting holes are both provided on the second lower positioning member 223.

[0079] In this embodiment, the packaging structure further includes a first protective component 51 and a second protective component 52. The first protective component 51 is disposed on the side of the first positioning component 21 away from the positioning space and is mounted on the base 10. The first protective component 51 includes a first frame portion 511 and a first reinforcing portion 512 connected to each other. The first frame portion 511 forms a rectangular structure, and the first reinforcing portion 512 is disposed at the diagonal of the rectangular structure. This structural arrangement allows the first protective component 51 to protect and limit the positioning component 21, thereby further enhancing the end stability of the packaging structure.

[0080] Specifically, the first frame portion 511 includes a first protective member 5111, a second protective member 5112, and a third protective member 5113 connected end to end. The first protective member 5111, the second protective member 5112, and the third protective member 5113 form a rectangular structure. The first protective member 5111 and the third protective member 5113 are used to abut against the first positioning component 21, and the second protective member 5112 is used to abut against the first upper positioning member 216. This structural arrangement enhances the structural stability of the first enclosure component 51 itself, while supporting the first positioning component 21 and preventing the first positioning component 21 from swaying left and right during transportation.

[0081] In this embodiment, the packaging structure further includes a first protective component 51 and a second protective component 52. The second protective component 52 is disposed on the side of the second positioning component 22 away from the positioning space and is mounted on the base 10. The second protective component 52 includes a second frame portion 521 and a second reinforcing portion 522 connected to each other. The second frame portion 521 forms a rectangular structure, and the second reinforcing portion 522 is disposed at the diagonal of the rectangular structure. This structural arrangement allows the second protective component 52 to protect and limit the positioning component 22, thereby further enhancing the end stability of the packaging structure.

[0082] Specifically, the second frame portion 521 includes a fourth protective member 5211, a fifth protective member 5212, and a sixth protective member 5213 connected end to end. These three members form a rectangular structure. The fourth and sixth protective members 5211 and 5213 abut against the second positioning component 22, while the fifth protective member 5212 abuts against the second upper positioning component 222. This structural arrangement enhances the structural stability of the second enclosure component 52 and supports the second positioning component 22, preventing it from swaying laterally during transportation.

[0083] Specifically, the packaging structure also includes an outer cover and outer strapping. The outer cover forms an accommodating space, within which the first positioning component 21, the second positioning component 22, the first protective component 51, and the second protective component 52 are all located. The outer strapping is used to cover the outer cover. This structural arrangement allows for comprehensive protection of the first positioning component 21, the second positioning component 22, the first protective component 51, and the second protective component 52 through the outer cover and outer strapping, further enhancing the overall integrity of the packaging structure.

[0084] In this embodiment, the packaging structure also includes an inner strapping strap 60. A limiting notch 11 is provided at the edge of the base 10. A first limiting groove 215 is provided on the side of the first positioning component 21 away from the positioning space. The limiting notch 11 and the first limiting groove 215 are opposite each other, and both the limiting notch 11 and the first limiting groove 215 are used to limit the inner strapping strap 60. With this structural arrangement, the inner strapping strap 60 can be limited by the first limiting groove 215 and the limiting notch 11, preventing the position of the inner strapping strap 60 from shifting and affecting the integrity of the packaging structure.

[0085] Specifically, the packaging structure also includes an inner strapping strap 60. A limiting notch 11 is provided at the edge of the base 10. A second limiting groove 221 is provided on the side of the second positioning component 22 away from the positioning space. The limiting notch 11 and the second limiting groove 221 are opposite each other, and both the limiting notch 11 and the limiting groove 221 are used to limit the inner strapping strap 60. With this structural arrangement, the inner strapping strap 60 can be limited by the second limiting groove 221 and the limiting notch 11, preventing the inner strapping strap 60 from shifting position and affecting the overall integrity of the packaging structure.

[0086] Specifically, the inner strapping 60 includes a transverse strapping 61 and a longitudinal strapping 62. The limiting notch 11, the first limiting groove 215, and the second limiting groove 221 are all used to limit the longitudinal strapping 62. The transverse strapping 61 is located on the side of the longitudinal strapping 62 away from the positioning space. With this structural arrangement, the overall integrity of the packaging structure can be enhanced by the transverse strapping 61 and the longitudinal strapping 62, preventing the components from dispersing and shaking during transportation.

[0087] In this embodiment, the base 10 includes a first base portion 12, a second base portion 13, and a third base portion 14 connected sequentially. A first positioning component 21, a second positioning component 22, a first enclosure component 51, and a second enclosure component 52 are all disposed on the side of the third base portion 14 away from the first base portion 12. The second base portion 13 includes multiple end supports 131 and multiple middle supports 132. The end supports 131 are disposed at both ends of the first base portion 12, and the multiple middle supports 132 are disposed in the middle of the first base portion 12 and arranged in an array. A limiting notch 11 is disposed on the third base portion 14. This structural arrangement allows the first base portion 12 and the third base portion 14 to be connected through the multiple end supports 131 and multiple middle supports 132 of the second base portion 13, while simultaneously enhancing the structural strength of the base 10. Furthermore, this arrangement allows forklifts to insert themselves into the gaps of the second base portion 13, facilitating the transportation of the packaged structure.

[0088] In this embodiment, a 10mm thick board (equivalent to the filling part 31) is added to the middle section above the wooden pallet (equivalent to the third base part 14). Positioning lines are drawn at the four corners of the pallet. M5*45 self-tapping screws are used to fix the lower EPP slot (equivalent to the first lower positioning part 217 and the second lower positioning part 223) to the positioning lines at both ends of the pallet. Then, corrugated cardboard (equivalent to the wear-resistant part 32) is laid on top of the board to prevent the edges of the photovoltaic module 70 from being scratched and damaged by friction with the wooden pallet during transportation. After completion, the height of the slot (equivalent to the first positioning groove 211 and the second positioning groove) is consistent with the height after the board and corrugated cardboard are added in the middle. When the module is placed in the slot, it can protect the corners of the photovoltaic module 70 and make the edges of the photovoltaic module 70 fully contact the corrugated cardboard, so that the force can be evenly distributed. After the pallet accessories are installed, the photovoltaic module 70 is inserted into the slot in one go, and then the upper EPP slot (equivalent to the first upper positioning part) is fixed. 216 and the second upper positioning component 222) are embedded at both ends of the upper part, and an EVA limiting slot (equivalent to the third positioning component 23) is added in the middle of the upper part to make the photovoltaic module 70 more stable during transportation and prevent the risk of bending and collision. Two lifting brackets 40 are placed to protect the top edge of the photovoltaic module 70 and prevent the risk of damage to the photovoltaic module 70 caused by the strapping squeeze during hoisting at the project site. Finally, N-shaped wooden guards (equivalent to the first enclosure component 51 and the second enclosure component 52) ​​are placed at both ends to increase stability. They are tightened laterally with inner packing straps 60 to ensure the integrity of each component on the pallet and prevent left and right swaying and tipping. The EPP upper slot is designed with a limiting step for the inner packing straps 60 (equivalent to the first limiting groove 215 and the second limiting groove 221). A packing limiting groove (equivalent to the limiting notch 11) is also opened at the edge of the pallet. This can prevent the inner packing straps 60 from slipping and causing damage to the components when packing longitudinally along the long side.

[0089] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: the edge of the back frame component without A and B sides is in complete contact with the tray, increasing the stress area of ​​the photovoltaic module, making the module more stable during transportation, and reducing collisions caused by shaking.
