[0011] It adopts a double-layer box structure, with the two boxes flexibly connected by a high-elasticity rubber side support component. The side support component uses an elastic metal sheet and a non-Newtonian fluid composite filling layer inside. It absorbs impact kinetic energy through the deformation of the elastic sheet, and with the unique shear thickening effect of the non-Newtonian fluid, it forms a dual energy dissipation mechanism. Its impact energy absorption efficiency is significantly improved compared with traditional materials. In terms of environmental performance, all components use fully recyclable TPE thermoplastic elastomer and bio-based biodegradable polyester materials, which comply with the EU REACH environmental standards. The packaging system is also innovatively equipped with a cushioning airbag group, including a bottom array air cushion unit and a side wall folding airbag curtain. The air cushion unit adopts a small bubble honeycomb structure design to optimize the space compression rate and maintain a compressed state during transportation. The transportation volume is reduced by about 60% compared with traditional EPS foam packaging, which combines excellent protection performance and transportation economy. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0020] Example:
[0021] Please see Figures 1-4 The present invention provides a technical solution: a shockproof packaging box, including an outer box 10 and an inner box 20, wherein a side support assembly 30 for supporting the inner box 20 is installed inside the outer box 10, and a buffer airbag 40 is installed between the outer box 10 and the inner box 20.
[0022] The side support assembly 30 has an inner cavity 310 inside, and multiple spring pieces 320 are installed inside the inner cavity 310. The inner cavity 310 is also filled with a filling layer 330.
[0023] Preferably, the opening of the outer casing 10 is provided with a top cover 120 and a dustproof flap 110, and the edge of the top cover 120 is provided with an insertion tongue 130. Specifically, the top cover 120 and the dustproof flap 110 are provided to close the opening of the outer casing 10.
[0024] Preferably, the filling layer 330 is a biodegradable non-Newtonian fluid medium. Specifically, when subjected to rapid impacts such as collisions or vibrations, the non-Newtonian fluid will instantly harden. In synergy with the deformation of the spring sheet 320, the impact energy is dissipated through fluid viscosity and absorbed by the deformation of the spring sheet 320, which significantly improves the buffering efficiency.
[0025] Preferably, the buffer airbag 40 includes a bottom airbag assembly 410 and side airbag curtains 420. The bottom airbag assembly 410 is in the shape of a cross and is installed between the lower surface of the inner box 20 and the inner wall of the outer box 10. Multiple side airbag curtains 420 are fixed to the edge of the bottom airbag assembly 410 and are located between the outer wall of the inner box 20 and the inner wall of the outer box 10. Specifically, the buffer airbag 40 wraps around the inner box 20, providing excellent protection. The buffer airbag 40 adopts a small bubble honeycomb structure, which can reduce the cross-section and avoid occupying a large internal space while ensuring the buffering effect.
[0026] Working principle: When in use, unfold and fix the outer box 10 and inner box 20, then insert the side support component 30 into the four corners of the outer box 10. Next, install the buffer airbag 40 inside the outer box 10, unfold and inflate it. Finally, install the inner box 20 inside the outer box 10 through the side support component 30. At this time, the assembly is complete. The goods can be placed in the inner box 20 and sealed by the top cover 120, dustproof flap 110 and insertion tongue 130. When the outer box 10 is impacted, the elastic piece 320 deforms to absorb the impact kinetic energy. Combined with the shear thickening effect of the non-Newtonian fluid of the filling layer 330, a dual energy dissipation mechanism is formed to protect the goods inside the inner box 20. At the same time, the buffer airbag 40 also plays a cushioning role.
