Description

Technical Field

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

[0002] Photovoltaic modules are the core and most important component of a solar power generation system. Their function is to convert solar energy into electrical energy, which is then either stored in batteries in off-grid systems, connected to loads, or connected to the grid. The production process of photovoltaic modules is complex, generally including: material feeding, string welding, layout, stacking, lamination, glass bonding, EL (electroluminescence) appearance testing, edge sealing, lamination, edge trimming, flipping inspection, frame assembly, junction box assembly, potting, curing, cleaning, IV (inductance testing), insulation withstand voltage testing, EL testing, FQC (finished quality control) appearance testing, grading, and packaging.

[0003] In related technologies, a vertical packaging method is commonly used, where packaging boxes are fitted over the photovoltaic modules along their long side. This packaging not only protects the product from physical, chemical, and biological damage but also facilitates stacking and storage, and adapts to different transportation methods. However, vertically packaged boxes are too tall, making it difficult for personnel to fit the boxes over the photovoltaic modules during packaging operations, resulting in low packaging efficiency. Utility Model Content

[0004] Therefore, it is necessary to overcome the shortcomings of existing technologies and provide a packaging box for photovoltaic modules that facilitates packaging operations and has high packaging efficiency.

[0005] A packaging box for photovoltaic modules, the packaging box for photovoltaic modules comprising:

[0006] The enclosure has a slot on one side along its length and a snap-fit ​​part on the other side. The snap-fit ​​part is used to snap into the slot, and when the snap-fit ​​part is snapped into the slot, the enclosure forms a chamber for installing photovoltaic modules.

[0007] In one embodiment, the enclosure includes a plurality of panels connected sequentially along its length, and a first bendable portion is provided between two adjacent panels.

[0008] In one embodiment, the first bendable portion is provided as a groove, which extends from one end of the enclosure to the other end of the enclosure along the width direction of the enclosure.

[0009] In one embodiment, the enclosure further includes a mating plate connected to the panel at the head, wherein one of the snap-fit ​​portion and the slot is disposed on the mating plate and the other is disposed on the panel at the tail.

[0010] In one embodiment, a second bendable portion is provided at the location between the panel on the head and the mating plate.

[0011] In one embodiment, the snap-fit ​​portion includes a plurality of snap heads connected sequentially along the length direction of the enclosure, and the snap groove includes a plurality of snap holes connected sequentially along the length direction of the enclosure, wherein the plurality of snap heads and the plurality of snap holes are snapped into each other in a one-to-one manner.

[0012] In one embodiment, the card head is configured as a column with a circular axial cross section, and all the columns include a first column and a second column alternately arranged along the length direction of the surrounding plate, and the diameter of the first column is greater than the diameter of the second column.

[0013] In one embodiment, the diameter of the first column is set to 4mm-4.5mm, the diameter of the second column is set to 3.5mm-4mm; and / or, the number of the card heads is 3 to 6.

[0014] In one embodiment, the card head is a sphere, and all the spheres include a first sphere and a second sphere that are alternately arranged along the length of the enclosure (10), and the diameter of the first sphere is larger than the diameter of the second sphere.

[0015] In one embodiment, there is one snap-fit ​​part and one slot, each of which extends from one end of the enclosure to the other end along the width direction of the enclosure; or, there are multiple snap-fit ​​parts and multiple slots, with each snap-fit ​​part corresponding to a slot, and the multiple snap-fit ​​parts are spaced apart sequentially along the width direction of the enclosure, and the multiple slots are spaced apart sequentially along the width direction of the enclosure.

[0016] The aforementioned photovoltaic module packaging box stacks multiple photovoltaic modules together, and then a surrounding panel is arranged around the stacked modules to enclose them. The snap-fit ​​parts then engage with the slots, allowing the stacked photovoltaic modules to be installed within the cavity formed by the surrounding panel, thus completing the packaging process. This eliminates the need for nesting photovoltaic modules as in related technologies, simplifying the packaging process and increasing efficiency. Furthermore, after the surrounding panel is closed, the opposite sides move closer together, aligning the snap-fit ​​parts with the slots and securing them together by pressing, resulting in a quick and reliable locking operation.

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] See Figures 1 to 4 , Figure 1 A structural diagram of a photovoltaic module packaging box according to an embodiment of this application is shown in its unfolded state. Figure 2 It shows Figure 1 Enlarged structural diagram at point A. Figure 3 It shows Figure 1 Enlarged structural diagram at point B. Figure 4 It shows Figure 1Enlarged structural view at point C. One embodiment of this application provides a packaging box for photovoltaic modules, comprising: a side panel 10. The side panel 10 has a slot 11 on one side along its length and a latching part 12 on the other side. The latching part 12 engages with the slot 11. When the latching part 12 is latched and fixed in the slot 11, the opposite sides of the side panel 10 are connected to each other and enclose a cavity. The cavity is used to install photovoltaic modules.

[0027] The aforementioned photovoltaic module packaging box stacks multiple photovoltaic modules together, and then a surrounding panel 10 is arranged around the stacked photovoltaic modules to enclose them. The snap-fit ​​part 12 then engages with the snap-fit ​​slot 11, allowing the stacked photovoltaic modules to be installed inside the cavity formed by the surrounding panel 10, thus completing the packaging operation. Therefore, it eliminates the need for the nested mounting method used in related technologies, facilitating the packaging operation and increasing packaging efficiency. Furthermore, after the surrounding panel 10 is closed, the opposite sides move closer together, aligning the snap-fit ​​part 12 with the snap-fit ​​slot 11, and then pressing them together for secure fastening, making the snap-fit ​​operation quick and reliable.

[0028] In addition, the packaging method of the photovoltaic module packaging box in this embodiment does not require Velcro, which can save the use of Velcro and save costs. Compared with connection methods such as Velcro, it can improve the connection reliability of the opposite sides of the enclosure 10 along the length direction, and the area of ​​the side connection is reduced, which reduces the amount of material used and lowers the cost.

[0029] It should be noted that, in this embodiment, the length direction of the enclosure 10 is as follows: Figure 1 As shown by the x-axis, the width direction of the enclosure 10 is as follows: Figure 1 As shown on the y-axis.

[0030] It should also be noted that the shape of the chamber matches that of the multiple photovoltaic modules stacked together. In this way, when the enclosure 10 is wrapped around the outside of the multiple photovoltaic modules stacked together, it fits against the outer wall of the multiple photovoltaic modules stacked together, providing a relatively stable fixing effect for each photovoltaic module, thus facilitating transportation; at the same time, the overall structure is compact and the volume is small.

[0031] Please see Figure 1 and Figure 4 In one embodiment, the enclosure 10 includes a plurality of panels 13 connected sequentially along its length. A first bendable portion 14 is provided between two adjacent panels 13. Thus, the first bendable portion 14 is easy to bend, which facilitates the bending of the enclosure 10, resulting in a plurality of panels 13, and enabling it to be tightly fitted to the exterior of a plurality of stacked photovoltaic modules.

[0032] For example, the specific structural form of the first bendable portion 14 is varied, as long as it satisfies the requirement that when a force is applied to the surrounding plate 10, the first bendable portion 14 is easier to bend than other parts of the surrounding plate 10. For example, the thickness of the sheet material at the first bendable portion 14 is less than the thickness of other parts of the surrounding plate 10. Specifically, the first bendable portion 14 is, for example, a groove provided on the surrounding plate 10. Optionally, the number of grooves can be one extending from one end of the surrounding plate 10 to the other along the width direction of the surrounding plate 10, or multiple grooves arranged sequentially along the width direction of the surrounding plate 10; the specific method is not limited here. Furthermore, for example, the hardness of the material of the first bendable portion 14 is less than the hardness of the material of other parts of the surrounding plate 10.

[0033] In this embodiment, the first bendable portion 14 is specifically, for example, a groove. The groove extends from one end of the surrounding plate 10 to the other end of the surrounding plate 10 along the width direction of the surrounding plate 10.

[0034] Based on the aforementioned embodiments, the first bendable portion 14 is made of the same material as other parts of the surrounding plate 10, and is specifically configured as an integrated structure. Optionally, the groove in the surrounding plate 10 is obtained by stamping or milling.

[0035] Based on the aforementioned embodiments, the width of the groove is, for example, 10mm to 20mm. This setting ensures that the width of the groove is appropriate, which facilitates the bending operation of the enclosure 10, while preventing the width from being too large and thus reducing the structural strength of the enclosure 10.

[0036] Please see Figure 1 and Figure 3 In one embodiment, the enclosure 10 further includes a mating plate 15 connected to the head panel 13. One of the snap-fit ​​portion 12 and the slot 11 is disposed on the mating plate 15, and the other is disposed on the tail panel 13. Thus, by bending the mating plate 15, the mating plate 15 and the tail panel 13 can be made to be on the same plane, thereby facilitating the stable snap-fit ​​of the snap-fit ​​portion 12 and the slot 11 together.

[0037] Specifically, when the snap-fit ​​part 12 is disposed on the docking plate 15, the snap-fit ​​slot 11 is disposed on the rear panel 13 accordingly; conversely, when the snap-fit ​​slot 11 is disposed on the docking plate 15, the snap-fit ​​part 12 is disposed on the rear panel 13 accordingly.

[0038] It should be noted that the first panel 13 refers to the panel 13 that is ranked first, while the last panel 13 refers to the panel 13 that is ranked last.

[0039] In one embodiment, a second bendable portion 16 is provided between the head panel 13 and the mating plate 15. Thus, the second bendable portion 16 is easy to bend, which facilitates the bending of the mating plate 15. After bending, it is beneficial to make the mating plate 15 and the tail panel 13 on the same surface, thereby facilitating the snap-fit ​​operation between the snap-fit ​​portion 12 and the snap-fit ​​slot 11.

[0040] Specifically, the plurality of panels 13 include a first plate 131, a second plate 132, a third plate 133, and a fourth plate 134 connected in sequence. The first plate 131 is the head panel 13, and the fourth plate 134 is the tail panel 13. The side of the first plate 131 opposite to the second plate 132 is connected to the mating plate 15, and a second bendable portion 16 is provided between the first plate 131 and the mating plate 15.

[0041] Furthermore, similar to the arrangement of the first bendable portion 14, the specific structural form of the second bendable portion 16 is also varied, as long as it satisfies the requirement that when a force is applied to the surrounding plate 10, the second bendable portion 16 is easier to bend than other parts of the surrounding plate 10. For example, the thickness of the sheet material at the second bendable portion 16 is less than the thickness of other parts of the surrounding plate 10. Specifically, the second bendable portion 16 can be, for example, a groove provided on the surrounding plate 10. Optionally, the number of grooves can be one extending from one end of the surrounding plate 10 to the other along the width direction of the surrounding plate 10, or multiple grooves arranged sequentially along the width direction of the surrounding plate 10; the specific method is not limited here. Another example is that the hardness of the material of the second bendable portion 16 is less than the hardness of the material of other parts of the surrounding plate 10.

[0042] Similar to the arrangement of the first bendable portion 14, the second bendable portion 16 in this embodiment is specifically, for example, a groove. The groove extends from one end of the surrounding plate 10 to the other end along the width direction of the surrounding plate 10. Furthermore, the second bendable portion 16 is made of the same material as other parts of the surrounding plate 10 and is specifically configured as an integral structure. Optionally, the groove is formed by stamping or milling the surrounding plate 10.

[0043] Please see Figure 2 and Figure 3 or Figures 5 to 7 In one embodiment, the latching part 12 includes a plurality of latch heads 121 sequentially connected along the length direction of the surrounding plate 10, and the latching groove 11 includes a plurality of latch holes 111 sequentially connected along the length direction of the surrounding plate 10. The plurality of latch heads 121 and the plurality of latch holes 111 are engaged in a one-to-one engagement. Thus, when the latching part 12 is latched and fixed inside the latching groove 11, the plurality of latch heads 121 and the plurality of latch holes 111 are engaged in a one-to-one engagement, thereby achieving a stable connection between the latching part 12 and the latching groove 11, and the latching part 12 and the latching groove 11 will not easily separate from each other.

[0044] In one embodiment, the locking head 121 is a cylinder with a circular axial cross-section, and all cylinders are arranged in an alternating pattern of large and small diameters. Specifically, all cylinders include a first cylinder and a second cylinder alternately arranged along the length of the surrounding plate 10, and the diameter of the first cylinder is larger than the diameter of the second cylinder. Thus, when each locking head 121 engages with each locking hole 111, it has better interlocking properties and stronger stability. Optionally, each cylinder extends from one end of the surrounding plate 10 to the other end along the width direction of the surrounding plate 10, and each locking hole 111 extends from one end of the surrounding plate 10 to the other end along the width direction of the surrounding plate 10. In this way, there is one locking part 12 and one locking groove 11, and each locking part 12 and locking groove 11 extends from one end of the surrounding plate 10 to the other end along the width direction of the surrounding plate 10.

[0045] Of course, as some optional solutions, the snap-fit ​​part 12 and the slot 11 can be provided in multiple ways, with multiple snap-fit ​​parts 12 and multiple slots 11 arranged one-to-one. The multiple snap-fit ​​parts 12 are arranged at intervals along the width direction of the surrounding plate 10, and the multiple slots 11 are arranged at intervals along the width direction of the surrounding plate 10.

[0046] Specifically, the diameter of the first column is, but is not limited to, 4mm-4.5mm, and the diameter of the second column is, but is not limited to, 3.5mm-4mm.

[0047] For example, the number of clip heads 121 may be, but is not limited to, 3 to 6, specifically, 3, 4, 5 or 6. This number of clip heads 121 is suitable because, on the one hand, a larger number of clip heads 121 ensures assembly stability; on the other hand, an excessive number of clip heads 121 does not cause installation inconvenience. In other words, a smaller number of clip heads 121 allows the snap-fit ​​part 12 to be easily snapped into place inside the clip slot 11.

[0048] Of course, as some optional options, the number of card headers 121 can also be set to 1, 2 or more than 6.

[0049] Since the number of card slots 111 is the same as the number of card heads 121, the specific setting method of card slots 111 refers to the specific setting method of card heads 121, and will not be repeated here.

[0050] In one embodiment, the locking head 121 can also be a sphere, with all the spheres arranged in an alternating pattern of large and small diameters. Specifically, all the spheres include a first sphere and a second sphere alternately arranged along the length of the surrounding plate 10, and the diameter of the first sphere is larger than the diameter of the second sphere. In this way, when each locking head 121 is engaged with each locking hole 111, it has better interlocking performance and stronger stability.

[0051] Based on the aforementioned embodiments, when the card head 121 is set as a sphere, in order to improve the connection stability between the two sides of the surrounding plate 10, multiple card contacts 12 and multiple card slots 11 are provided. Multiple card contacts 12 and multiple card slots 11 are provided in a one-to-one correspondence. Multiple card contacts 12 are arranged sequentially at intervals along the width direction of the surrounding plate 10, and multiple card slots 11 are arranged sequentially at intervals along the width direction of the surrounding plate 10.

[0052] In some embodiments, the enclosure 10 includes, but is not limited to, corrugated board, specifically, BC corrugated board, i.e., formed by combining 3 to 5 layers of board. The thickness of the enclosure 10 is, for example, 5 mm to 7 mm, the length of the enclosure 10 is, for example, 3400 mm to 4600 mm, and the width of the enclosure 10 is, for example, 1700 mm to 2900 mm. The specific dimensions of the enclosure 10 can be flexibly adjusted and set according to the size of the photovoltaic modules and the number of photovoltaic modules to be packaged.

[0053] It should be noted that in this embodiment, the "snap-fitting part 12, mating plate 15, first bendable part 14, and second bendable part 16" can be "part of the panel 13", that is, the "snap-fitting part 12, mating plate 15, first bendable part 14, and second bendable part 16" can be integrally formed with "other parts of the panel 13"; or they can be separate components from "other parts of the panel 13", that is, the "snap-fitting part 12, mating plate 15, first bendable part 14, and second bendable part 16" can be manufactured independently and then combined with "other parts of the panel 13" to form a whole.
