[0022] The present utility model will be further described below in conjunction with embodiments.

[0023] Embodiment 1:

[0024] Please refer to Figure 1 - Figure 2 , the buffer and anti-collision layer 14 includes a buffer pad 141, a buffer cavity 142 opened inside the buffer pad 141, a filler 1421 filled inside the buffer cavity 142, and ventilation holes opened on the outer surface of the buffer pad 141. The buffer cavity 142 is communicated with the ventilation holes. The buffer pad 141 provides a flexible protection structure, which is convenient for deforming when being impacted by an external force, so as to absorb and disperse the impact energy and reduce the impact force. The buffer cavity 142 and the filler 1421 are convenient for further enhancing the buffer effect, and utilize the compression deformation of the filler 1421 to absorb more impact energy and reduce the direct action of the external force on the sandwich panel body 1. At the same time, the air in the buffer cavity 142 is convenient to be discharged through the ventilation holes, which helps to quickly release the pressure and reduce the impact force.

[0025] The buffer pad 141 is a component made of a rubber material, and the filler 1421 is a component made of a foamed polyethylene material. Both the rubber material and the foamed polyethylene material have excellent elasticity and shock absorption performance, which are convenient for effectively absorbing and dispersing the external impact force. Through the combined action of the filler 1421 and the buffer pad 141, double buffer and anti-collision protection is provided.

[0026] The base material layer 11 is a component made of an aluminum alloy material. The aluminum alloy material has high strength and rigidity, which is convenient for providing sufficient support force to ensure the structural stability of the sandwich panel body 1.

[0027] The heat-insulating layer 12 is a component made of a polyurethane foam material. The polyurethane foam has an extremely low thermal conductivity, which is convenient for effectively preventing heat transfer to maintain the low temperature state inside the cold storage and reduce the cold loss.

[0028] The waterproof layer 13 is a component made of a high-density polyethylene film material. The high-density polyethylene film has a high-density molecular structure, which is convenient for effectively blocking water penetration to provide a reliable waterproof barrier.

[0029] The heat-insulating layer 15 is a component made of a rock wool material. The rock wool material has a very low thermal conductivity, which is convenient for effectively preventing heat transfer and playing a heat-insulating function.

[0030] The fireproof layer 16 is a component made of calcium silicate board material, which has natural flame retardant properties and is not easy to burn, facilitating the effective delay of the spread of fire in case of a fire.

[0031] The protective layer 17 is a component made of polyvinyl chloride material, which has good corrosion resistance to most chemical substances such as acids, alkalis, and salts and is suitable for various environments.

[0032] The heat insulation layer 12 facilitates effectively maintaining the low temperature inside the cold storage, reducing the loss of cold quantity, and improving the energy utilization efficiency. The waterproof layer 13 is used to prevent water penetration. The heat insulation layer 15 facilitates ensuring that the temperature inside the cold storage is more stable and further saves energy consumption. The fireproof layer 16 provides flame retardant performance to slow down the speed of fire spread. As the outer protection, the fireproof layer 16 facilitates reducing wear and tear during daily use to extend the service life. The buffer and anti-collision layer 14 is used to absorb external impact forces. The buffer pad 141 provides a flexible protection structure, facilitating deformation when subjected to external impact forces, thereby absorbing and dispersing the impact energy to reduce the impact force. The buffer cavity 142 and the filler 1421 facilitate further enhancing the buffer effect, using the compression deformation of the filler 1421 to absorb more impact energy and reducing the direct action of the external force on the sandwich panel body 1. At the same time, the air in the buffer cavity 142 facilitates being discharged through the ventilation holes, helping to quickly release pressure and reduce the impact force.
