[0054] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0055] like Figures 1 to 6As shown, an embodiment of the present invention provides a packaging structure of a photovoltaic component, the packaging structure includes a base 10, a first positioning component 21 and a second positioning component 22, the first positioning component 21 and the second positioning component 22 are both arranged on the base 10, the first positioning component 21 is provided with a first positioning groove 211, the second positioning component 22 is provided with a second positioning groove, the first positioning groove 211 and the second positioning groove are arranged opposite to each other and enclose a positioning space for accommodating a photovoltaic component 70. The packaging structure also includes a filling component 30, which is arranged on the base 10 and is located between the first positioning component 21 and the second positioning component 22, and the bottom of the first positioning groove 211 and the bottom of the second positioning groove are both arranged flush with the side of the filling component 30 away from the base 10. Wherein, the sum of the spacing between the filling component 30 and the first positioning component 21 and the spacing 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] By adopting the packaging structure of the photovoltaic assembly provided by the embodiment of the present invention, the photovoltaic assembly 70 can be positioned and fixed by the first positioning assembly 21 and the second positioning assembly 22, so as to avoid the photovoltaic assembly 70 from tipping over or colliding during transportation. At the same time, since the first positioning groove 211 of the first positioning assembly 21 has a certain height compared with the base 10, and the second positioning groove of the second positioning assembly 22 also has a certain height compared with the base 10, this results in that when the photovoltaic assembly 70 is positioned and fixed by the first positioning assembly 21 and the second positioning assembly 22, the bottom side edge of the photovoltaic assembly 70 cannot contact the base 10. In this embodiment, the gap between the bottom side edge of the photovoltaic assembly 70 and the base 10 is filled by the setting of the filling assembly 30, so that the bottom side edge of the photovoltaic assembly 70 can be supported. And the setting of the size of the filling assembly 30 ensures the contact area between the photovoltaic assembly 70 and the base 10, so that the support of the photovoltaic assembly 70 is more stable, and the force of the photovoltaic assembly 70 during transportation is more uniform, so as to reduce the collision of the photovoltaic assembly 70 caused by transportation bumps. Therefore, the packaging structure of the photovoltaic module provided in this embodiment can solve the technical problem of uneven force on the photovoltaic module during transportation in the prior art.

[0057] Specifically, photovoltaic module 70 is a BIPV (building integrated photovoltaic) type photovoltaic module. Specifically, photovoltaic module 70 is a back frame module without A side and B side, that is, a back frame module with only C side. Among them, A side refers to the frame surface located on the top of the solar panel of the photovoltaic module and exposed to light, B side refers to the frame surface located on the side of the solar panel of the photovoltaic module, and C side refers to the frame surface located at the bottom of the solar panel of the photovoltaic module. Since BIPV type photovoltaic modules are different from conventional photovoltaic modules in structure and packaging and transportation methods, the packaging structure in this solution can better protect BIPV type photovoltaic modules during transportation according to their characteristics.

[0058] Specifically, considering the errors 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 5 cm and less than or equal to 10 cm.

[0059] Specifically, the filling component 30 includes a filling portion 31 and a wear-resistant portion 32, and the wear-resistant portion 32 is arranged on a side of the filling portion 31 away from the base 10. Wherein, along the direction from the first positioning component 21 to the second positioning component 22, the difference between the length of the wear-resistant portion 32 and the length of the filling portion 31 is greater than or equal to 0 cm and less than or equal to 10 cm. With such a structural arrangement, the gap between the bottom side edge of the photovoltaic component 70 and the base 10 can be filled by the setting of the filling portion 31, so that the bottom side edge of the photovoltaic component 70 can be supported. At the same time, the photovoltaic component 70 can be prevented from directly contacting and rubbing with the filling portion 31 by the setting of the wear-resistant portion 32, thereby preventing the photovoltaic component 70 from being scratched. In addition, making the difference between the length of the wear-resistant portion 32 and the length of the filling portion 31 greater than or equal to 0 cm and less than or equal to 10 cm can increase the contact area between the photovoltaic component 70 and the base 10 while retaining a certain assembly error margin, so that the support for the photovoltaic component 70 is more stable, and the force of the photovoltaic component 70 during transportation is more uniform.

[0060] Specifically, taking into account the errors 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 5 cm and less than or equal to 10 cm.

[0061] Specifically, the filling assembly 30 includes a filling portion 31 and a wear-resistant portion 32, and the wear-resistant portion 32 is arranged on the side of the filling portion 31 away from the base 10. Among them, 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. With such a structural arrangement, the gap between the bottom side edge of the photovoltaic assembly 70 and the base 10 can be filled by setting the filling portion 31, so that the bottom side edge of the photovoltaic assembly 70 can be supported. At the same time, the photovoltaic assembly 70 can be prevented from directly contacting and rubbing with the filling portion 31 by setting the wear-resistant portion 32, thereby preventing the photovoltaic assembly 70 from being scratched. In addition, making the thickness of the wear-resistant portion 32 greater than or equal to 2 mm and less than or equal to 5 mm can ensure its wear resistance, extend the service life of the wear-resistant portion 32 and reduce the deadweight of the filling assembly 30, thereby facilitating transportation.

[0062] Specifically, the filling component 30 includes a filling portion 31 and a wear-resistant portion 32, and the wear-resistant portion 32 is arranged on the side of the filling portion 31 away from the base 10. Among them, the thickness of the filling portion 31 is greater than or equal to 10mm and less than or equal to 15mm. Specifically, the thickness of the filling portion 31 is 10mm. With such a structural arrangement, the gap between the bottom side edge of the photovoltaic component 70 and the base 10 can be filled by the setting of the filling portion 31, so that the bottom side edge of the photovoltaic component 70 can be supported. At the same time, the photovoltaic component 70 can be prevented from directly contacting and rubbing with the filling portion 31 by the setting of the wear-resistant portion 32, thereby preventing the photovoltaic component 70 from being scratched. In addition, making the thickness of the filling portion 31 greater than or equal to 10mm and less than or equal to 15mm can effectively fill the gap between the bottom side edge of the photovoltaic component 70 and the base 10, thereby avoiding the filling portion 31 from being too thick and increasing the weight of the packaging structure, thereby ensuring the economy of the packaging structure.

[0063] Specifically, the filling assembly 30 includes a filling portion 31 and a wear-resistant portion 32, wherein the wear-resistant portion 32 is arranged on a side of the filling portion 31 away from the base 10. The filling portion 31 is made of a hard material. Specifically, the filling portion 31 is made of wood. With such a structural arrangement, the hard filling portion 31 can form a stable support for the bottom side of the photovoltaic assembly 70, ensuring that the uniformity of the force of the photovoltaic assembly 70 is not affected by bumps during transportation.

[0064] Specifically, in order to ensure uniform force on the bottom side edge of the photovoltaic assembly 70, the filling portion 31 is a plate-shaped structure.

[0065] Specifically, the filling assembly 30 includes a filling portion 31 and a wear-resistant portion 32, wherein the wear-resistant portion 32 is disposed on a side of the filling portion 31 away from the base 10. The wear-resistant portion 32 is made of corrugated paper or pearl cotton. With such a structural arrangement, the wear-resistant portion 32 made of corrugated paper or pearl cotton can contact the photovoltaic assembly 70, thereby preventing the photovoltaic assembly 70 from being directly contacted with the hard filling portion 31 and being scratched.

[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; a third positioning groove is provided on the third positioning component 23, and the notch of the third positioning groove is arranged toward the positioning space, so that at least part of the photovoltaic component 70 is inserted into the third positioning groove. With such a structural arrangement, the stability of the photovoltaic component 70 during transportation can be enhanced by the third positioning component 23, and the risk of bending or collision of the photovoltaic component 70 can be reduced.

[0067] Specifically, in order to further enhance the integrity of the packaging structure, the third positioning component 23 and the filling component 30 are arranged opposite to each other.

[0068] Specifically, the first positioning assembly 21 and the second positioning assembly 22 are both made of expanded polypropylene (EPP). With such a structural setting, the overall weight of the packaging structure can be reduced by the lower dead weight of EPP, thereby facilitating transportation. At the same time, EPP has good buffering performance. By positioning the photovoltaic assembly 70 with the first positioning assembly 21 and the second positioning assembly 22 made of EPP, the photovoltaic assembly 70 can be better protected and the vibration of the photovoltaic assembly 70 during transportation can be well buffered.

[0069] Specifically, the third positioning assembly 23 is made of ethylene-vinyl acetate copolymer (EVA). With such a structural setting, the overall weight of the packaging structure can be reduced by the lighter deadweight of EVA, thereby facilitating transportation. At the same time, ethylene-vinyl acetate copolymer EVA has good waterproof performance, corrosion resistance and anti-vibration performance. The photovoltaic assembly 70 is positioned by the third positioning assembly 23 made of EVA, which can better protect the photovoltaic assembly 70 and avoid vibration of the photovoltaic assembly 70 during transportation.

[0070] In this embodiment, the packaging structure further includes a hanging bracket 40, which is arranged between the first positioning assembly 21 and the second positioning assembly 22. The hanging bracket 40 is arranged around the positioning space and is spaced and arranged opposite to the base 10; the side of the hanging bracket 40 close to the base 10 is used to contact the edge of the photovoltaic assembly 70. Wherein, along the extension direction of the first positioning assembly 21, the width of the hanging bracket 40 is greater than or equal to the width of the first positioning assembly 21. With such a structural setting, the top edge of the photovoltaic assembly 70 can be protected by the setting of the hanging bracket 40, and the setting that the width of the hanging bracket 40 is greater than or equal to the width of the first positioning assembly 21 can ensure that when the side of the packaging structure is compressed, the pressure will not be transmitted to the photovoltaic assembly 70, thereby reducing the risk of damage to the photovoltaic assembly 70.

[0071] Specifically, the packaging structure also includes a hanging bracket 40, which is arranged between the first positioning component 21 and the second positioning component 22. The hanging bracket 40 is arranged around the positioning space and is spaced and arranged opposite to the base 10; the side of the hanging bracket 40 close to the base 10 is used to contact the edge of the photovoltaic component 70. Among them, the hanging bracket 40 includes a frame member 41 and a reinforcement member 42 that are connected to each other. The middle part of the frame member 41 is provided with a hollow opening, and the reinforcement member 42 is arranged in the hollow opening and extends along the extension direction of the first positioning component 21. With such a structural arrangement, the weight of the hanging bracket 40 can be reduced on the basis of protecting the top edge of the photovoltaic component 70 through the arrangement of the hanging bracket 40, so as to avoid the hanging bracket 40 being too heavy and squeezing the photovoltaic component 70. In addition, the arrangement of the reinforcement member 42 effectively enhances the overall stability of the structure of the hanging bracket 40 itself, and further improves the overall structural strength of the packaging structure.

[0072] Specifically, the packaging structure further includes a hanging bracket 40, which is arranged between the first positioning assembly 21 and the second positioning assembly 22. The hanging bracket 40 is arranged around the positioning space and is spaced and arranged opposite to the base 10; the side of the hanging bracket 40 close to the base 10 is used to contact the edge of the photovoltaic assembly 70. There are two hanging brackets 40, and the two hanging brackets 40 are respectively located on both sides of the third positioning assembly 23 and are in contact with the third positioning assembly 23. With such a structural setting, the top edge of the photovoltaic assembly 70 can be protected by the setting of two hanging brackets 40, so as to avoid the third positioning assembly 23 from interfering with the contact between the hanging bracket 40 and the photovoltaic assembly 70.

[0073] Specifically, the first positioning assembly 21 includes a plurality of first positioning protrusions 212 arranged in sequence and at intervals, and a first positioning groove 211 is formed between each of the first positioning protrusions 212; the first positioning assembly 21 also includes a first connection hole 213 and a second connection hole 214, both of which are used to connect with the base 10, and the first connection hole 213 is arranged on the first positioning protrusion 212 located at the end of the first positioning assembly 21; the second connection hole 214 is arranged on the first positioning protrusion 212 located at the middle of the first positioning assembly 21. With such a structural arrangement, multiple photovoltaic assemblies 70 can be positioned through the first positioning protrusion 212 and the first positioning groove 211, so as to avoid collision between multiple photovoltaic assemblies 70. At the same time, the arrangement of the first connection hole 213 and the second connection hole 214 can ensure a stable connection between the first positioning assembly 21 and the base 10, so as to stabilize the position of the first positioning assembly 21, and avoid affecting the positioning of the photovoltaic assembly 70 due to the displacement of the first positioning assembly 21.

[0074] Specifically, the first positioning assembly 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 positioning grooves of the first lower positioning member 217 are arranged relative to each other and are arranged around the positioning space. The first upper positioning member 216 and the first lower positioning member 217 are respectively used to position the top and bottom of the photovoltaic assembly 70. With such a structural arrangement, the positioning stability of the photovoltaic assembly 70 can be better improved and the risk of positioning failure can be reduced.

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

[0076] Specifically, the second positioning assembly 22 includes a plurality of second positioning protrusions arranged in sequence and at intervals, and a second positioning groove is formed between each second positioning protrusion; the second positioning assembly 22 also includes a third connection hole and a fourth connection hole, and the third connection hole and the fourth connection hole are both used to connect with the base 10, and the third connection hole is arranged on the second positioning protrusion located at the end of the second positioning assembly 22; the fourth connection hole is arranged on the second positioning protrusion located in the middle of the second positioning assembly 22. With such a structural arrangement, multiple photovoltaic assemblies 70 can be positioned by the second positioning protrusion and the second positioning groove, and multiple photovoltaic assemblies 70 can be prevented from colliding with each other. At the same time, the arrangement of the third connection hole and the fourth connection hole can ensure a stable connection between the second positioning assembly 22 and the base 10, so that the position of the second positioning assembly 22 is stable, and the positioning of the photovoltaic assembly 70 is prevented from being affected by the displacement of the second positioning assembly 22.

[0077] Specifically, the second positioning assembly 22 includes a second upper positioning member 222 and a second lower positioning member 223. The positioning groove of the second upper positioning member 222 and the positioning groove of the second lower positioning member 223 are arranged opposite to each other and are arranged around the positioning space. The second upper positioning member 222 and the second lower positioning member 223 are respectively used to position the top and bottom of the photovoltaic assembly 70. With such a structural arrangement, the positioning stability of the photovoltaic assembly 70 can be better improved and the risk of positioning failure can be reduced.

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

[0079] In this embodiment, the packaging structure further includes a first enclosure component 51 and a second enclosure component 52. The first enclosure component 51 is arranged on the side of the first positioning component 21 away from the positioning space and is arranged on the base 10; the first enclosure component 51 includes a first frame portion 511 and a first reinforcement portion 512 connected to each other, the first frame portion 511 forms a rectangular structure, and the first reinforcement portion 512 is arranged at the diagonal of the rectangular structure. With such a structural setting, the first positioning component 21 can be protected and limited by the first enclosure component 51, 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 in sequence, 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. With such a structural setting, the structural stability of the first enclosure component 51 itself can be enhanced, and the first positioning component 21 can be supported at the same time to prevent the first positioning component 21 from shaking left and right during transportation.

[0081] In this embodiment, the packaging structure further includes a first enclosure component 51 and a second enclosure component 52.
