AI Technical Summary
Existing insulated foam boxes have low impact resistance, are easily broken, and have insufficient shock absorption performance, making them unsuitable for transporting precision instruments and fragile items.
A support frame is set on the outside of the foam box, and a shock absorption mechanism is set inside, including corrugated rubber airbags and air chamber structure. The elastic deformation of the rubber airbags absorbs vibration energy, and high-strength plastic material is combined to enhance the overall structural strength.
The foam box has enhanced impact and breakage resistance, effectively protecting the items inside, especially providing better protection for precision instruments and fragile items in complex transportation scenarios.
