[0039] The top cover 200 has a first receiving portion 210 on the side facing the base tray 100, and a buckle portion 230 is provided on the inner side of the first receiving portion 210, which is used to snap onto the item 400 to be packaged.

[0040] The base tray 100 has a second receiving portion 110 on its side facing the top cover 200; the first receiving portion 210 and the second receiving portion 110 are used to enclose and receive the item 400 to be packaged;

[0041] The connecting piece 300 is located between the top cover 200 and the base tray 100, and is used to connect the top cover 200 and the base tray 100;

[0042] A first buffer cavity 220 is provided between the top cover 200 and the first receiving part 210;

[0043] A second buffer cavity 120 is provided between the base tray 100 and the second receiving part 110.

[0044] In this embodiment of the utility model, the self-locking packaging structure can be composed of a base tray 100, a top cover 200, and a connecting piece 300. The base tray 100 can be located on top of the item to be packaged 400, or at the bottom of the item to be packaged 400. The connecting piece 300 is located between the base tray 100 and the top cover 200, connecting the base tray 100 and the top cover 200, forming an integrated structure. A first receiving portion 210 is provided on the side of the top cover 200 facing the base tray 100, and a second receiving portion 110 is provided on the side of the base tray 100 facing the top cover 200. The first and second receiving portions 210 are positioned opposite each other. Since the top cover 200 is located on top of the item to be packaged 400, the first receiving portion 210 can secure and accommodate the top area of ​​the item to be packaged 400. Since the base tray 100 is located at the bottom of the item to be packaged 400, the second receiving portion 110 can secure and accommodate the bottom area of ​​the item to be packaged 400. The first receiving cavity and the second receiving portion 110 together enclose and accommodate the item to be packaged 400, and a latching portion 230 is provided on the inner side of the first receiving portion 210. The snap-fit ​​portion 230 engages with the item to be packaged 400, using the snap-fit ​​force to secure and lock the item 400, preventing movement and protecting it from shaking during transportation or storage. The first receiving portion 210 and the second receiving portion 110 can be circular, arc-shaped, or square; their shapes match the shape of the item 400, and this embodiment of the invention is not limited to any particular shape. By setting the shapes of the first receiving portion 210 and the second receiving portion 110 to match the shape of the item 400, it can be ensured that the first receiving portion 210 and the second receiving portion 110 can stably accommodate the item 400.

[0045] The item to be packaged, 400, can be any type of item, such as an electronic device as a whole or its components. For example, it could be the display component of a mobile phone or the mobile phone itself. It could also be a complete set or components of a household appliance. For example, it could be the outdoor unit of an air conditioner or the cooling fan of an air conditioner.

[0046] A first buffer cavity 220 is provided between the top cover 200 and the first receiving portion 210. The first buffer cavity 220 is a hollow cavity. When the first receiving portion 210 contains the item to be packaged 400, the first buffer cavity 220 cushions the movement of the first receiving portion 210. When a foreign object intrudes or the first receiving portion 210 is subjected to external force, the first buffer cavity 220 buffers the force, thereby buffering the impact on the first receiving portion 210, preventing the item to be packaged 400 from being damaged by external force, and protecting the item to be packaged 400.

[0047] A second buffer cavity 120 is provided between the base tray 100 and the second receiving portion 110. The second buffer cavity 120 is a hollow cavity. When the second receiving portion 110 contains the item to be packaged 400, the second buffer cavity 120 cushions the movement of the first receiving portion 210. When a foreign object intrudes or the second receiving portion 110 is subjected to external force, the second buffer cavity 120 buffers the force, thereby cushioning the impact on the second receiving portion 110, preventing the item to be packaged 400 from being damaged by external force, and protecting the item to be packaged 400.

[0048] The first buffer cavity 220 and the second buffer cavity 120 absorb impact energy. When the self-locking structure is impacted by an external force, the first buffer cavity 220 and the second buffer cavity 120 will dissipate energy through compression or deformation, reducing the impact force transmitted to the item to be packaged 400. They can also disperse stress concentration by altering the force transmission path, dispersing localized high stress to a larger area, preventing stress concentration from causing material breakage, and avoiding damage to the first receiving part 210 and the second receiving part 110. Furthermore, by using the cavity structure, the first buffer cavity 220 and the second buffer cavity 120 reduce material usage while maintaining structural strength, achieving lightweight and economic efficiency.

[0049] The depths of the first buffer cavity 220 and the second buffer cavity 120 can be determined according to actual needs, and this embodiment of the present invention does not impose a limitation. For example, the depths of the first buffer cavity 220 and the second buffer cavity 120 can be 20-25 mm.

[0050] In some examples, the first receiving portion 210 is a square flat groove, the edge of which is connected to the top of the item to be packaged 400; the snap-fit ​​portion 230 is disposed at the edge of the square flat groove and snaps into the item to be packaged 400.

[0051] In this embodiment of the invention, the first receiving portion 210 can be a square flat groove, that is, the first receiving portion 210 is a square groove with a flat bottom surface. The top of the item to be packaged 400 is connected to the edge of the square flat groove, thereby fixing the top of the item to be packaged 400. Furthermore, the snap-fit ​​portion 230 is provided with the edge of the square flat groove, protruding towards the item to be packaged 400 relative to the edge of the square flat groove, thereby snapping the item to be packaged 400 in place and further securing it.

[0052] In some examples, the base tray 100 is a square irregular groove, the edge of which is connected to the bottom of the item to be packaged 400.

[0053] In this embodiment of the utility model, the base tray 100 is a square irregular groove. The edge of the square irregular groove can surround and fix the bottom of the packaged item and connect with the bottom of the item to be packaged 400 so that the item to be packaged 400 will not sway from side to side.

[0054] In some embodiments, the latching portion 230 includes:

[0055] Several fasteners are arranged around the edge of the square flat groove.

[0056] The latching part 230 may include a plurality of latching components. The number of latching components can be set according to actual needs, such as 2, 5, 6, 8, etc., and this embodiment of the present invention does not limit the number. The latching components can be arranged around the edge of the square flat groove, so that the packaged item 400 can be latched from multiple different positions around the square flat groove, thereby better securing the packaged item 400.

[0057] In one example, there are four fasteners;

[0058] Two of the four fasteners are located on one side of the edge of the square flat groove, and the other two are located on the opposite side of the edge of the square flat groove.

[0059] In practical use, there can be four fasteners, which can be divided into two groups. One group is set on one side of the edge of the square flat groove, and the other group is set on the opposite side of the edge of the square flat groove. That is, two of the four fasteners are set on one side of the edge of the square flat groove, and the other two are set on the opposite side of the edge of the square flat groove. By fixing the fasteners on opposite sides, the packaged item 400 is secured, and the packaged item 400 can be evenly fastened.

[0060] Fasteners are structural elements that achieve connection or locking through elastic deformation. They can be permanent fasteners, with an inlet angle that allows the packaged item to engage with the fastener at a 40° angle, creating a self-locking state and ensuring stable fastening. Fasteners can be cantilevered, such as hook-type cantilever fasteners with a hook-shaped protrusion at the end. Sleeve-type cantilever fasteners use a collar structure for connection, offering high strength. They can also be ring-type fasteners, where a flange on a ring or cap engages with an annular groove. Spherical fasteners can also be used, with a ball head engaging a spherical groove, supporting multi-angle rotation. Finally, U-shaped fasteners feature a U-shaped cantilever design, providing bidirectional elasticity.

[0061] In one example, the base tray 100, the top cover 200, and the connecting piece 300 are manufactured using either vacuum forming or injection molding. Specifically, the base tray 100, top cover 200, and connecting piece 300 can be integrally manufactured using vacuum forming, by heating a plastic sheet to a softened state and then applying it to the mold surface using vacuum suction or mechanical pressure. After cooling, the product is demolded. Alternatively, they can be integrally manufactured using injection molding, by heating plastic granules to a molten state and injecting them into the cavity of a closed mold under high pressure. After cooling and solidification, the base tray 100, top cover 200, and connecting piece 300 are demolded. Furthermore, the mold can be a progressive mold, allowing multiple processes such as punching, bending, stretching, and forming to be completed sequentially through multiple stations in a single stroke of the press, thus improving production efficiency. The base tray 100, top cover 200, and connecting piece 300 can be made of the same material, including but not limited to: PVC (polyvinyl chloride), PP (polypropylene), PET (polyethylene terephthalate), PS (polystyrene), PETG (polyethylene terephthalate-1,4-cyclohexanediol), ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate), PE (polyethylene), PA (polyamide), and POM (polyoxymethylene resin). PVC is polymerized from vinyl chloride monomer and typically contains stabilizers and lubricants. It has good chemical resistance, is flame-retardant, wear-resistant, and has excellent electrical insulation properties. PP is a high-density, side-chain-free, highly crystalline linear polymer polymerized from propylene monomer. It has high heat resistance, good chemical resistance, and excellent electrical insulation. PET (polyethylene terephthalate) is polymerized from terephthalic acid and ethylene glycol. It has good optical properties and weather resistance, is non-toxic, and resistant to weak acids and organic solvents. PS is polymerized from styrene monomer. Colorless and transparent, PETG possesses excellent insulation and weather resistance. It is formed by the condensation polymerization of terephthalic acid, ethylene glycol, and 1,4-cyclohexanediethanol. It has high transparency, good toughness, excellent impact resistance, and is easy to process and mold. ABS is a copolymer of acrylonitrile, butadiene, and styrene. It has excellent overall performance, high strength, high rigidity, good impact resistance, and is easy to process and mold. PC is a thermoplastic plastic containing carbonate groups in its molecular backbone, primarily bisphenol A type aromatic PC. It is tasteless, odorless, non-toxic, transparent, has excellent mechanical properties, and high impact strength. PE is polymerized from ethylene monomers. It is non-toxic, has good flexibility, good impact resistance, and good transparency. PA's molecular structure contains repeating amide groups. It has high strength and abrasion resistance, good heat resistance and chemical stability, and a low coefficient of friction. POM includes homopolymer and copolymer polyoxymethylene. It has excellent overall performance, high crystallinity, and high density. The balance between material thickness and packaging volume can be determined according to requirements. While ensuring that the material thickness is sufficient to support the 400mm cushioning strength of the packaged items, the packaging volume can be effectively compressed, reducing the use of packaging materials, resulting in lighter packaging and lower transportation costs.

[0062] This utility model embodiment includes a self-locking packaging structure comprising a base tray 100, a top cover 200, and a connecting piece 300.
