Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module packaging structure, and in particular to a packaging box for a modular photovoltaic module. Background Technology

[0002] After solar photovoltaic panels leave the factory, multiple layers of panels are stacked and placed inside a cardboard box. The cardboard box is then placed on a wooden pallet and connected to the pallet with cable ties, completing the stacking and packaging of the photovoltaic modules. However, this traditional packaging method does not provide any enclosure around the sides and four corners of the cardboard box. As a result, the circumferential support relies entirely on the cardboard box itself and the cable ties. During transportation, severe bumps and shaking often create significant impact forces on the circumferential outwards, causing damage to the cardboard box and cable ties, resulting in damage to the photovoltaic modules and rendering the cardboard box unusable. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a packaging box for modular photovoltaic modules, which solves the problem that existing packaging structures are easily damaged by circumferential impacts during transportation.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A packaging box for a modular photovoltaic module includes a pallet, on the top of which a packaging carton is supported. Each of the four corners of the pallet is provided with a side-enclosing structure, the inner surface of which is respectively attached to the corner and outer surface of the packaging carton.

[0006] The side enclosure structure consists of a corner plate and two side plates fixed to the two sides of the corner plate. The inner middle of the side plate has an inner protrusion that fits the outer facade of the packaging carton. The lower ends of the corner plate and the side plates are connected to the pallet. The two inner facades of the corner plate fit the two sides of the corner of the packaging carton. The corner plate is arranged longitudinally, and the two side plates on each corner plate are arranged at an angle. The distance between the upper ends of the two side plates on each corner plate is smaller than the distance between the lower ends.

[0007] Optionally, the corner plate has several first mounting holes at the position of the long side of the outermost crossbeam of the tray, and the end of the outermost crossbeam of the tray has a first tensioning hole at the position of the first mounting holes. The first tensioning hole passes through the crossbeam in the width direction of the crossbeam. A first bolt is inserted into the first mounting hole and the first tensioning hole. The first bolt is threaded to a first nut at the end to lock the crossbeam of the tray and the corner plate.

[0008] Optionally, a second mounting hole is provided at the lower end of a side plate that is directly opposite the long side of the outermost crossbeam of the tray on the corner plate. A second tensioning hole is provided at the position where the long side of the outermost crossbeam of the tray is directly opposite the second mounting hole. The second tensioning hole passes through the crossbeam in the width direction of the crossbeam. A second bolt is inserted into the second tensioning hole and the second mounting hole. The second bolt is connected to a second nut at the end by a thread to tighten the crossbeam of the tray and the side plate.

[0009] Optionally, a washer is fixed to one side of a side plate that is directly opposite the long side of the outermost crossbeam of the pallet, and the other side of the washer abuts against the outer wall of the crossbeam of the pallet. A sleeve frame is fixed to the lower end of a side plate that is directly opposite the end of the crossbeam on the inner side of the pallet, and the sleeve frame is fitted onto the end of the crossbeam on the inner side of the pallet.

[0010] Optionally, a third mounting hole is provided at the opposite position of the two bent parts of the sleeve frame, and a third tensioning hole is provided on the crossbeam on which the tray is sleeved in the sleeve frame, opposite the third mounting hole. A third bolt is inserted into the third mounting hole and the third tensioning hole, and the third bolt is threaded to the end of the third nut to tighten the sleeve frame and the crossbeam.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. This utility model features a detachable side-enclosing structure installed at the four corners of the pallet. The corner plates of the side-enclosing structure abut against the corners of the pallet and the packaging carton, while the side plates abut against the outer surface of the packaging carton. The side plates are also inclined, thus providing a protective barrier against the corners and the outer surface of the packaging carton. The side-enclosing structure withstands the circumferential impact of the photovoltaic modules during transportation, thereby reducing the probability of damage to the packaging carton and the outer straps and effectively improving the yield rate of the product during transportation.

[0013] 2. The side panels on both sides of the side enclosure structure provided by this utility model are arranged at an angle and connected to the tray at the lower end, so that the side enclosure structure can be stably connected to the tray, and the resistance to circumferential impact is improved. The side enclosure structure is connected to the tray with bolts, so that the side enclosure structure can be disassembled as needed. If lateral protection is not required, it can be removed. The modular structure improves the adaptability of the packaging structure. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 6 This embodiment provides a packaging box for a modular photovoltaic module, including a tray 1. The top of the tray 1 supports a packaging carton 2. Each of the four corners of the tray 1 is provided with a side enclosure structure. The side enclosure structure consists of a corner plate 3 and two side plates 4 respectively fixed to the two sides of the corner plate 3. The corner plate 3 is arranged longitudinally, and the two side plates 4 on each corner plate 3 are arranged at an angle. The distance between the upper ends of the two side plates 4 on each corner plate 3 is smaller than the distance between the lower ends. The two inner surfaces of the corner plate 3 are respectively attached to the two sides of the corner of the packaging carton 2. An inner protrusion is formed in the middle of the inner side of the side plate 4, and the inner protrusion is attached to the outer surface of the packaging carton 2.

[0023] Because the pallet 1 has a side-enclosing structure at its four corners, the corner plate 3 can surround the corners of the packaging carton 2, protecting the corners of the packaging carton 2 and mitigating circumferential impact. The two side plates 4 abut against the outer surface of the packaging carton 2, mitigating circumferential impact. This forms a structure that supports the packaging carton 2 from the outside. Thus, during long-distance transportation, when the photovoltaic panels inside are subjected to lateral impact, the side-enclosing structure can be used for support and withstand the impact force, preventing damage to the carton or the straps on the outside of the carton, thereby improving the product yield during transportation.

[0024] In particular, the side panels 4 are arranged at an angle, and the two side panels 4 on both sides of each corner panel 3 are diagonally connected to the tray, tightening the corner panel 3, forming a triangular structure, which makes the entire side enclosure structure more stable when connected to the tray 1, improves its strength, and greatly enhances its impact resistance.

[0025] The connection and fixation between the corner plate 3 and the tray 1 are achieved by opening two first mounting holes 5 on the long side of the outermost crossbeam of the tray 1 directly opposite the corner plate 3, and opening a first tensioning hole 6 at the end of the outermost crossbeam of the tray 1 directly opposite the first mounting holes 5. The first tensioning hole 6 extends through the crossbeam in the width direction. During installation, the first mounting holes 5 are aligned with the first tensioning hole 6. Then, a first bolt 7 is inserted into the first mounting holes 5 and the first tensioning hole 6, and a first nut 8 is threaded onto the first bolt 7 to lock the crossbeam of the tray 1 and the corner plate 3, thus completing the connection and fixation of the corner plate 3.

[0026] The connection between one side plate 4 and the tray 1 is achieved by having a second mounting hole 9 at the lower end of the side plate 4, which is directly opposite the long side of the outermost crossbeam of the tray 1, and a second tensioning hole 10, which is directly opposite the second mounting hole 9, on the long side of the outermost crossbeam of the tray 1. The second tensioning hole 10 extends through the crossbeam in the width direction. During installation, a second bolt 11 is inserted into the second tensioning hole 10 and the second mounting hole 9. A washer 18 is fixed on the side of the side plate 4, which is directly opposite the long side of the outermost crossbeam of the tray 1, close to the tray 1. The other side of the washer 18 abuts against the outer wall of the crossbeam of the tray 1. The second bolt 11 passes through the washer 18, allowing the side plate 4 to fit flat against the outer wall of the tray 1. Then, a second nut 12 is threaded onto the end of the second bolt 11 to tighten the crossbeam of the tray 1 and the side plate 4, thus completing the connection and fixing of one side plate 4 to the tray 1.

[0027] The connection between the other side plate 4 and the tray 1 is accomplished by the sleeve frame 13. The sleeve frame 13 is fixed to the lower end of the side plate 4, which is directly opposite the end of the crossbeam inside the tray 1 on the corner plate 3. The sleeve frame 13 is fitted onto the end of the crossbeam inside the tray 1. A third mounting hole 14 is opened at the opposite position of the two bent parts of the sleeve frame 13. A third tensioning hole 15 is opened on the crossbeam inside the sleeve frame 13, which is directly opposite the third mounting hole 14. During installation, a third bolt 16 is inserted into the third mounting hole 14 and the third tensioning hole 15. A third nut 17 is threaded onto the end of the third bolt 16 to tighten the sleeve frame 13 and the crossbeam, thus completing the fixing of the other side plate 4 and the tray 1.

[0028] The entire side enclosure structure is connected to the pallet 1 by bolts, making it detachable. This modular structural arrangement allows the pallet 1 to be installed with or without the side enclosure structure, thus improving the adaptability of this packaging structure.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
