Description

Technical Field

[0001] This application relates to the field of photovoltaic transport technology, and in particular to a packaging box for photovoltaic modules. Background Technology

[0002] A photovoltaic (PV) module is the smallest indivisible power generation unit that converts solar energy into direct current using the photovoltaic effect. A PV module consists of tempered glass, an EVA (Ethylene Vinyl Acetate) sealing layer, a TPT (Thermoplastic Polyfluoroethylene) backsheet, and an aluminum alloy frame.

[0003] Photovoltaic modules require packaging boxes for loading during sample delivery, testing, and long-distance transportation to ensure they are not subjected to impacts or bumps during transport. Current methods use a top-and-bottom assembly approach, with adjacent modules separated by dividers at the bottom of the box. While these dividers effectively secure the bottom of the modules, the lack of a fixed structure at the top reduces their stability within the box. This makes the modules more susceptible to tilting and impacts during transport, potentially leading to damage. Utility Model Content

[0004] This application provides a packaging box for photovoltaic modules, which aims to solve the problem of poor stability of photovoltaic modules inside the packaging box.

[0005] To achieve the above objectives, this application provides a packaging box for photovoltaic modules, comprising: A base plate and a top plate, wherein the base plate and the top plate are arranged opposite to each other; A first side plate and a second side plate are arranged opposite to each other. The bottom plate, the top plate, the first side plate, and the second side plate form a mounting cavity, which is used to accommodate photovoltaic modules. A guide mechanism is provided, wherein multiple guide mechanisms are provided, and all multiple guide mechanisms are provided in the mounting cavity. Each guide mechanism has a guide groove, and the guide groove is used to accommodate photovoltaic modules. A positioning mechanism is disposed within the mounting cavity, and the positioning mechanism is used to cooperate with the guiding mechanism to fix the photovoltaic module within the mounting cavity.

[0006] Optionally, the positioning mechanism includes a first positioning component, which is disposed opposite to the guide mechanism. The guide mechanism is installed on one of the base plate and the top plate, and the first positioning component is installed on the other of the base plate and the top plate.

[0007] Optionally, the first positioning component includes a first positioning member and a plurality of first partition plates. The first positioning member has a first positioning channel, and the plurality of first partition plates are spaced apart in the first positioning channel. The interval between each pair of adjacent first partition plates forms a first isolation cavity, which is used to fix the photovoltaic module.

[0008] Optionally, the first positioning member includes a first positioning plate and a second positioning plate, the second positioning plate being set at an angle to the first positioning plate, and the first partition plate being connected between the first positioning plate and the second positioning plate; The guiding mechanism is installed on one of the base plate and the top plate, and the first positioning plate is installed on the other of the base plate and the top plate.

[0009] Optionally, the first positioning plate has a first outer surface, and the top plate has a first end face; The first end face extends beyond the first outer surface, or the first end face is flush with the first outer surface.

[0010] Optionally, the positioning mechanism includes a second positioning component, which is disposed between the bottom plate and the top plate and connected to the first side plate and the second side plate.

[0015] In the photovoltaic module packaging box of this application embodiment, through the above technical solution, the packaging box is equipped with a guide mechanism inside the mounting cavity. The photovoltaic module can be pushed into the mounting cavity by means of the guide groove. Under the guidance of the guide groove, the position of the photovoltaic module in the packaging box can be accurately positioned with the positioning mechanism without repeatedly adjusting the position of the photovoltaic module in the packaging box. The cooperation between the guide groove and the positioning mechanism not only helps to keep the photovoltaic module stable inside the packaging box and avoid the photovoltaic module tilting inside the packaging box and causing bumps, but also reduces the difficulty and time of loading and unloading the photovoltaic module and increases the loading and unloading speed.

[0021] 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.

[0022] Please refer to Figures 1 to 5 This application provides a packaging box for photovoltaic modules, comprising a base plate 110 and a top plate 120, a first side plate 130 and a second side plate 140, a guiding mechanism 300, and a positioning mechanism 200. The packaging box is used to load photovoltaic modules 500 and has intersecting first direction X, second direction Y, and third direction Z. The packaging box is made of materials including but not limited to wood or iron, thereby ensuring that the packaging box can be reused and extending its service life.

[0023] The base plate 110 is generally a support plate for the packaging box, meaning the packaging box is typically placed on a load-bearing surface via the base plate 110. A base 600 can also be provided at the bottom of the base plate 110. The base 600 prevents the base plate 110 from directly contacting the load-bearing surface, preventing debris on the load-bearing surface from damaging the structure of the base plate 110 and helping to protect the structure of the base plate 110 from damage. When both the base plate 110 and the top plate 120 are equipped with guide mechanisms 300, the guide grooves 301 of the guide mechanisms 300 of the base plate 110 and the top plate 120 can respectively accommodate the two sides of the photovoltaic module 500 in the third direction Z. This allows the photovoltaic module 500 to be positioned along the guide grooves 301. Figure 4The stability of the process of pushing into the installation cavity 101 is ensured to prevent the photovoltaic module 500 from tilting when moving along the guide groove 301.

[0024] The first side panel 130 and the second side panel 140 are respectively connected to the bottom panel 110 and the top panel 120 on the second direction Y at their respective two edges in the third direction Z. The first side panel 130, the second side panel 140, the bottom panel 110 and the top panel 120 are manufactured by integral molding or assembly splicing, and form the main structure of the packaging box.

[0025] In this embodiment, please refer to Figures 1 to 3 The packaging box also includes a first door 400 and a second door 410.

[0026] The first box door 400 is connected to the first side plate 130 or the second side plate 140 in the third direction Z, and the first box door 400 is used to close the first box opening 102. The first box door 400 is hinged to the first side plate 130 or the second side plate 140, and the first box opening 102 can be closed by the first box door 400. When the first positioning component 210 at the first box opening 102 is movably disposed on at least one of the bottom plate 110 and the top plate 120, after the first box door 400 is closed, the first box door 400 can limit the first positioning component 210, so that the first positioning component 210 always maintains the fixation of the photovoltaic module 500, and with the cooperation of the guide groove 301, the photovoltaic module 500 can be stably fixed in the packaging box.

[0027] The second door 410 is connected to the first side plate 130 or the second side plate 140 in the third direction Z, and the second door 410 and the first door 400 are arranged opposite each other in the first direction X, and the second door 410 is used to close the second opening 103. The second door 410 is hinged to the first side plate 130 or the second side plate 140, and the second opening 103 can be closed by the second door 410. When the first positioning component 210 at the second opening 103 is movably disposed in at least one of the bottom plate 110 and the top plate 120, after the second door 410 is closed, the second door 410 can limit the first positioning component 210, so that the first positioning component 210 always keeps the photovoltaic module 500 fixed, and with the cooperation of the guide groove 301, the photovoltaic module 500 can be stably fixed in the packaging box.

[0028] For details, please refer to Figure 1 and Figure 3The bottom plate 110 and top plate 120 are positioned opposite each other in the third direction Z. The first side plate 130 and the second side plate 140 are positioned opposite each other in the second direction Y. The bottom plate 110, top plate 120, first side plate 130, and second side plate 140 enclose a mounting cavity 101 for accommodating the photovoltaic module 500. The mounting cavity 101 has a first opening 102 and a second opening 103 positioned opposite each other in the first direction X. One of the first direction X and the second direction Y is the length direction of the packaging box, and the other is the width direction of the packaging box. The third direction Z is the height direction of the packaging box. The first opening 102 and the second opening 103 are located on both sides of the packaging box along the length or width direction, respectively. Thus, the photovoltaic module 500 can be installed into the mounting cavity 101 through the first opening 102 or the second opening 103. The mounting cavity 101 can accommodate photovoltaic modules 500 with a length of 1722mm to 2465mm and a width of 992mm to 1303mm.

[0029] It should be noted that in other embodiments, the mounting cavity 101 may also accommodate photovoltaic modules 500 of other sizes, and this is not the only limitation.

[0030] Please refer to Figure 1 , Figure 2 and Figure 4 Multiple guiding mechanisms 300 are provided, each disposed within the mounting cavity 101. Each guiding mechanism 300 has a guide groove 301 extending along a first direction X, and the guide groove 301 is used to accommodate the photovoltaic module 500. The guide groove 301 can communicate with a first opening 102 and a second opening 103, respectively. The multiple guiding mechanisms 300 are evenly arranged within the mounting cavity 101 along a second direction Y. The photovoltaic module 500 can be installed into the mounting cavity 101 through the guide groove 301 from either the first opening 102 or the second opening 103. The guiding mechanisms 300 can be disposed at at least one of the bottom plate 110 and the top plate 120. That is, the guiding mechanisms 300 can be disposed only on the bottom plate 110 or the top plate 120, or simultaneously on both the bottom plate 110 and the top plate 120. It should be noted that the present application... Figures 1 to 3 The structure of the base plate 110 with a guide mechanism 300 is shown.

[0031] It should be noted that the width of the guide groove 301 matches the thickness of the photovoltaic module 500. The photovoltaic module 500 is generally thin, resulting in a smaller width for the guide groove 301. To reduce the difficulty of inserting the photovoltaic module 500 into the guide groove 301 and improve installation efficiency, the two ends of the guide mechanism 300 are positioned adjacent to the first opening 102 and the second opening 103, respectively. This facilitates alignment of the photovoltaic module 500 with the guide groove 301, allowing it to be easily installed into the mounting cavity 101.

[0032] Please refer to Figures 1 to 3 as well as Figure 5 A positioning mechanism 200 is disposed within the mounting cavity 101. The positioning mechanism 200 cooperates with the guiding mechanism 300 to fix the photovoltaic module 500 within the mounting cavity 101. The positioning mechanism 200 can be disposed at at least one of the first opening 102 and the second opening 103. That is, the positioning mechanism 200 can be disposed only at the first opening 102 or the second opening 103, or it can be disposed at both the first opening 102 and the second opening 103. Where the positioning mechanism 200 is disposed at both the first opening 102 and the second opening 103, it can simultaneously fix both sides of the photovoltaic module 500. Compared to the case where the photovoltaic module 500 is disposed only at the first opening 102 or the second opening 103, this allows the photovoltaic module 500 to maintain higher stability within the mounting cavity 101. It should be noted that the present application… Figures 1 to 3 The diagram illustrates the structure in which the positioning mechanism 200 is simultaneously located at the first container opening 102 and the second container opening 103.

[0033] Please refer to Figure 4 and Figure 5 The guide groove 301 is used to accommodate the side of the photovoltaic module 500 in the third direction Z, and the positioning mechanism 200 is used to fix the photovoltaic module 500 in the mounting cavity 101.

[0034] Through the above technical solution, the packaging box, by setting a guide mechanism 300 inside the mounting cavity 101, allows the photovoltaic module 500 to be pushed into the mounting cavity 101 by means of the guide groove 301. Guided by the guide groove 301, the photovoltaic module 500 can be accurately positioned with the positioning mechanism 200 without repeatedly adjusting its position inside the packaging box. The cooperation between the guide groove 301 and the positioning mechanism 200 not only helps to keep the photovoltaic module 500 stable inside the packaging box, preventing it from tilting and bumping, but also reduces the difficulty and time required for loading and unloading the photovoltaic module 500, and increases the loading and unloading speed.

[0035] In some embodiments, please refer to Figures 1 to 4The positioning mechanism 200 includes a first positioning component 210, which is disposed opposite to the guide mechanism 300. The guide mechanism 300 is installed on one of the base plate 110 and the top plate 120, and the first positioning component 210 is installed on the other of the base plate 110 and the top plate 120.

[0036] Specifically, when the base plate 110 is equipped with a guide mechanism 300, the first positioning component 210 is movably connected to the top plate 120. When the guide mechanism 300 is located on the base plate 110, the photovoltaic module 500 is aligned with and placed into the guide groove 301 of the guide mechanism 300 on the Z-direction side, that is, the bottom of the photovoltaic module 500 is aligned with and placed into the guide groove 301, and then the photovoltaic module 500 can be pushed into the mounting cavity 101 along the guide groove 301. After the photovoltaic module 500 is completely pushed into the mounting cavity 101, the position of the first positioning component 210 on the top plate 120 is adjusted, thereby fixing the side of the photovoltaic module 500 adjacent to the top plate 120, that is, fixing the top of the photovoltaic module 500. In this way, the bottom of the photovoltaic module 500 can be inserted into the guide groove 301, and the top of the photovoltaic module 500 can be fixed by the first positioning component 210. The two work together to separate the photovoltaic module 500 in the mounting cavity 101. This not only reduces the difficulty of loading the photovoltaic module 500 into the packaging box and improves the loading and unloading efficiency of the photovoltaic module 500, but also keeps the photovoltaic module 500 stable in the packaging box, preventing the photovoltaic module 500 from tilting and colliding with adjacent photovoltaic modules 500 and being damaged.

[0037] Furthermore, when the top plate 120 is equipped with a guide mechanism 300, the first positioning component 210 is movably connected to the bottom plate 110. When the guide mechanism 300 is located on the top plate 120, the photovoltaic module 500 is aligned with and placed into the guide groove 301 of the guide mechanism 300 on the Z-direction side, that is, the top of the photovoltaic module 500 is aligned with and placed into the guide groove 301, and then the photovoltaic module 500 can be pushed into the mounting cavity 101 along the guide groove 301. After the photovoltaic module 500 is completely pushed into the mounting cavity 101, the position of the first positioning component 210 on the bottom plate 110 is adjusted, thereby fixing the side of the photovoltaic module 500 adjacent to the bottom plate 110, that is, fixing the bottom of the photovoltaic module 500. In this way, the top of the photovoltaic module 500 can be inserted into the guide groove 301, and the bottom of the photovoltaic module 500 can be fixed by the first positioning component 210. The two work together to separate the photovoltaic module 500 in the mounting cavity 101. This not only reduces the difficulty of loading the photovoltaic module 500 into the packaging box and improves the loading and unloading efficiency of the photovoltaic module 500, but also keeps the photovoltaic module 500 stable in the packaging box, preventing the photovoltaic module 500 from tilting and colliding with adjacent photovoltaic modules 500 and being damaged.

[0038] In some embodiments, please refer to Figures 5 to 7 The first positioning component 210 includes a first positioning element 211 and a plurality of first partition plates 212. The first positioning element 211 has a first positioning channel 213. The plurality of first partition plates 212 are spaced apart within the first positioning channel 213, and the interval between each pair of adjacent first partition plates 212 forms a first isolation cavity 2130. The first isolation cavity 2130 is used to fix the photovoltaic module 500. Specifically, in the second direction Y, the end face of the first positioning element 211 is triangular. After the photovoltaic module 500 is fully pushed into the packaging box along the guide groove 301, the position of the first positioning element 211 is adjusted so that the first positioning channel 213 faces the photovoltaic module 500, and the plurality of photovoltaic modules 500 in the mounting cavity 101 are respectively accommodated in the first isolation cavity 2130. In this way, each photovoltaic module 500 in the packaging box can be fixed by a set of guide grooves 301 and the first isolation cavity 2130, thereby realizing the spaced placement of multiple photovoltaic modules 500 in the packaging box and avoiding the problem of collision between adjacent photovoltaic modules 500.

[0039] It should be noted that when the first box opening 102 is used solely as a loading and unloading port for the photovoltaic module 500, the positioning mechanism 200 at the first box opening 102 is movably disposed at at least one of the bottom plate 110 and top plate 120 at the first box opening 102, so as to avoid the positioning mechanism 200 affecting the loading and unloading of the photovoltaic module 500 at the first box opening 102. The positioning mechanism 200 at the second box opening 103 can be fixedly disposed at at least one of the bottom plate 110 and top plate 120 at the second box opening 103.

[0040] When the second box opening 103 is used only as a loading and unloading port for the photovoltaic module 500, the positioning mechanism 200 at the second box opening 103 is movably set at at least one of the bottom plate 110 and the top plate 120 at the second box opening 103 to avoid the positioning mechanism 200 affecting the loading and unloading of the photovoltaic module 500 at the second box opening 103. The positioning mechanism 200 at the first box opening 102 can be fixedly set at at least one of the bottom plate 110 and the top plate 120 at the first box opening 102.

[0041] When both the first box opening 102 and the second box opening 103 serve as loading and unloading ports for the photovoltaic module 500, the positioning mechanisms 200 at the first box opening 102 and the second box opening 103 are movably disposed at at least one of the bottom plate 110 and the top plate 120 at the first box opening 102 and the second box opening 103, so as to avoid the positioning mechanisms 200 affecting the loading and unloading of the photovoltaic module 500 at the first box opening 102 and the second box opening 103.

[0042] Furthermore, the first positioning member 211 is rotatably connected to at least one of the base plate 110 and the top plate 120. Further, a rotating member 700 may be provided between the first positioning member 211 and the base plate 110, enabling a rotatable connection between them. Similarly, a rotating member 700 may be provided between the first positioning member 211 and the top plate 120, enabling a rotatable connection between them. The rotating member 700 can be a hinge or other rotating components in the prior art, and is not limited to any particular type.

[0043] In some embodiments, please continue to refer to Figures 5 to 7 The first positioning component 211 includes a first positioning plate 2110 and a second positioning plate 2111. The second positioning plate 2111 is set at an angle to the first positioning plate 2110, and a first partition plate 212 is connected between the first positioning plate 2110 and the second positioning plate 2111. Specifically, the first positioning component 211 is used to fix the corner of the photovoltaic module 500. In the second direction Y, the angle between the second positioning plate 2111 and the first positioning plate 2110 is a right angle. In this way, the first positioning channel 213 formed by the second positioning plate 2111 and the first positioning plate 2110 can be adapted to the corner structure of multiple photovoltaic modules 500 in the packaging box, so that the first isolation cavity 2130 can accommodate the corner of the photovoltaic module 500, and in conjunction with the guide groove 301, adjacent photovoltaic modules 500 can be fixed and separated to prevent the photovoltaic modules 500 from tilting in the packaging box and causing collisions.

[0044] In addition, the guide mechanism 300 is installed on one of the base plate 110 and the top plate 120, and the first positioning plate 2110 is installed on the other of the base plate 110 and the top plate 120.

[0045] Specifically, when the base plate 110 is equipped with a guide mechanism 300, the first positioning plate 2110 is movably connected to the top plate 120. When either the first box opening 102 or the second box opening 103 serves as the loading / unloading port for the photovoltaic module 500, the first positioning plate 2110 located at the loading / unloading port is movably positioned on the top plate 120 to prevent the first positioning element 211 from affecting the loading / unloading of the photovoltaic module 500. The first positioning plate 2110 at the other box opening, which is not used as the loading / unloading port for the packaging box, can be fixedly positioned on the top plate 120. When both the first box opening 102 and the second box opening 103 serve as the loading / unloading ports for the photovoltaic module 500, the first positioning plates 2110 at both box openings are movably positioned on the top plate 120 to prevent the first positioning element 211 from affecting the loading / unloading of the photovoltaic module 500.

[0046] When the top plate 120 is equipped with a guide mechanism 300, the first positioning plate 2110 is movably connected to the bottom plate 110. When one of the first box opening 102 and the second box opening 103 serves as the loading and unloading port for the photovoltaic module 500, the first positioning plate 2110 located at the loading and unloading port is movably disposed on the bottom plate 110 to prevent the first positioning element 211 from affecting the loading and unloading of the photovoltaic module 500. When the other of the first box opening 102 and the second box opening 103 does not serve as the loading and unloading port for the packaging box, the first positioning plate 2110 can be fixedly disposed on the bottom plate 110. When both the first box opening 102 and the second box opening 103 serve as the loading and unloading ports for the photovoltaic module 500, the first positioning plates 2110 at both box openings are movably disposed on the bottom plate 110 to prevent the first positioning element 211 from affecting the loading and unloading of the photovoltaic module 500.

[0047] In some embodiments, please refer to Figures 1 to 3 as well as Figure 7 The first positioning plate 2110 has a first outer surface 21101 in the first direction X, and the top plate 120 has a first end face 121 in the first direction X. The first end face 121 extends beyond the first outer surface 21101, or the first end face 121 is flush with the first outer surface 21101. Specifically, when the photovoltaic module 500 is fully pushed into the packaging box, the corners of the photovoltaic module 500 are located in the first isolation cavity 2130, and the first outer surface 21101 of the first positioning plate 2110 does not extend beyond the first end face 121 of the top plate 120, that is, the first positioning plate 2110 does not extend out of the mounting cavity 101 in the first direction X. In this way, when closing the first box door 400 and the second box door 410, gaps at the edges of the first box opening 102 and the second box opening 103 due to the first positioning member 211 protruding relative to the top plate 120 can be avoided, which may even cause the box door to be difficult to close.

[0048] It is easy to understand that the bottom plate 110 and top plate 120 of the packaging box have the same structural configuration, and the bottom plate 110 and top plate 120 have overlapping first end faces 121. The first outer surface 21101 of the first positioning plate 2110 does not extend beyond the first end face 121 of the top plate 120, that is, the first outer surface 21101 of the first positioning plate 2110 does not extend beyond the first end face 121 of the bottom plate 110.

[0049] In some embodiments, please refer to Figures 1 to 3 as well as Figure 5 and Figure 6The positioning mechanism 200 includes a second positioning component 220, which is disposed between the bottom plate 110 and the top plate 120 and connected to the first side plate 130 and the second side plate 140. The second positioning component 220 is located at at least one of the first box opening 102 and the second box opening 103. Specifically, the second positioning component 220 is movably connected between the first side plate 130 and the second side plate 140 to fix and isolate the photovoltaic module 500 on its side in the first direction X. After the photovoltaic module 500 is completely placed in the packaging box, the second positioning component 220 can be installed between the first side plate 130 and the second side plate 140, thereby fixing the side of adjacent photovoltaic modules 500 in the first direction X. In conjunction with the first positioning component 210, this further improves the stability of the photovoltaic module 500 within the packaging box.

[0050] In some embodiments, please refer to further details. Figures 1 to 3 as well as Figure 5 and Figure 6 The second positioning component 220 includes a second positioning member 221 and a plurality of second partition plates 222. The plurality of second partition plates 222 are spaced apart on the second positioning member 221 along the second direction Y, and the interval between each two adjacent second partition plates 222 forms a second isolation cavity 223, which is used to fix the photovoltaic module 500. Specifically, the second positioning member 221 has a plate-like structure. In the third direction Z, the distance between the second positioning member 221 and the first positioning member 211 can be 200mm to 400mm. After the photovoltaic module 500 is completely placed in the packaging box, the two ends of the second positioning member 221 are respectively abutted against the first side plate 130 and the second side plate 140, so that the second positioning member 221 is locked between the first side plate 130 and the second side plate 140, and the side of the photovoltaic module 500 in the first direction X enters the second isolation cavity 223. Therefore, the second positioning member 221 can be used to insert the side portions of multiple photovoltaic modules 500 in the first direction X into the second isolation cavity 223 respectively. Based on the first isolation cavity 2130 on the first positioning member 211 fixing the corner of the photovoltaic module 500, the side portion of the photovoltaic module 500 is further fixed, which helps to improve the stability of the photovoltaic module 500 in the packaging box.

[0051] In some embodiments, the second positioning member 221 has a second outer surface 2211 in the first direction X, and the first side plate 130 has a second end face 1301 in the first direction X; the second end face 1301 extends beyond the second outer surface 2211, or the second end face 1301 is flush with the second outer surface 2211. Specifically, after the photovoltaic module 500 is completely pushed into the packaging box, the second positioning member 221 is engaged between the first side plate 130 and the second side plate 140, and the side portions of multiple photovoltaic modules 500 in the first direction X respectively enter the second isolation cavity 223. The second outer surface 2211 of the second positioning member 221 does not extend beyond the second end face 1301 of the first side plate 130, that is, the second positioning member 221 does not extend out of the mounting cavity 101 in the first direction X. In this way, when closing the first box door 400 and the second box door 410, gaps can be avoided at the edges of the first box opening 102 and the second box opening 103 due to the second positioning member 221 protruding relative to the first side plate 130, which could even cause the box door to be difficult to close.

[0052] It is easy to understand that the first side panel 130 and the second side panel 140 of the packaging box have the same structural configuration, and the second side panel 140 and the first side panel 130 have a second end face 1301 that overlaps. The second outer surface 2211 of the second positioning member 221 does not extend beyond the second end face 1301 of the first side panel 130, that is, the second outer surface 2211 of the second positioning member 221 also does not extend beyond the second end face 1301 of the second side panel 140.

[0053] In some embodiments, please refer to Figures 1 to 4 The guiding mechanism 300 includes a plurality of guide members 310 arranged along the first direction X, with a guide groove 301 formed between each pair of adjacent guide members 310. Specifically, the guide member 310 has an L-shaped plate structure. Each pair of L-shaped plate-shaped guide members 310 forms a guide groove 301. Thus, when the photovoltaic module 500 is installed into the packaging box, the photovoltaic module 500 is pushed, causing it to move between the two L-shaped plate-shaped guide members 310. The guide members 310 on both sides can limit the photovoltaic module 500, thereby pushing the photovoltaic module 500 into the mounting cavity 101 and ensuring that the photovoltaic module 500 accurately enters the first isolation cavity 2130. Under the combined action of the guide groove 301 and the first isolation cavity 2130, the photovoltaic module 500 can be fixed in the packaging box, preventing the photovoltaic module 500 from tilting and colliding with adjacent photovoltaic modules 500, thus improving the stability of the photovoltaic module 500 in the packaging box.

[0054] It should be noted that the gap between the first side plate 130 and the second side plate 140 and their adjacent guide members 310 can also form a guide groove 301. In this way, an additional guide groove 301 can be formed between the first side plate 130 and the second side plate 140 on both sides of the mounting cavity 101 and the adjacent guide members 310, thereby increasing the capacity of the photovoltaic modules 500 in the mounting cavity 101, so that the packaging box can carry more photovoltaic modules 500.

[0055] In some embodiments, please continue to refer to Figures 1 to 4 Each guide groove 301 is equipped with multiple roller assemblies 320. Each roller assembly 320 includes an axle 321 and a wheel body 322. The two ends of the axle 321 are connected to the guide member 310, and the wheel body 322 is sleeved on the axle 321. Specifically, when the guide mechanism 300 is set on the base plate 110, the multiple roller assemblies 320, consisting of the axle 321 and the wheel body 322, set in the guide groove 301, enable the photovoltaic module 500 to move along the guide groove 301 under the action of the rollers. This avoids friction between the photovoltaic module 500 and the base plate 110, reduces wear on the photovoltaic module 500, and reduces the difficulty of pushing the photovoltaic module 500 into the packaging box, thereby improving the loading efficiency of the photovoltaic module 500.
