[0002] With increasing consumer demand for temperature-sensitive goods such as refrigerated food and pharmaceuticals, the refrigerated truck industry has ushered in unprecedented development opportunities. Statistics show that from January to April 2024, sales of refrigerated trucks in my country reached 8,506 units, demonstrating strong market growth. It is projected that by the end of 2024, China's refrigerated truck fleet will reach 477,000 units, representing a significant year-on-year increase. Globally, the refrigerated transport market is also maintaining steady growth.

[0003] As a crucial component of refrigerated logistics, small and medium-sized refrigerated trucks are gaining popularity due to their flexibility, low cost, and energy efficiency, and are widely used in fresh food delivery, pharmaceutical transportation, and chemical raw material transport. Currently, the common practice of converting small passenger vehicles into refrigerated compartments involves emptying the interior, removing the original interior trim, roof, and side walls, and then installing insulation materials such as polyurethane foam. This process is complex, lacks standardization, and fails to guarantee effective refrigeration. Furthermore, the absence of fixed storage compartments within the compartment compromises the safety of fragile items during transport.

[0004] Therefore, the interior design of the cargo compartment is particularly important when converting small and medium-sized trucks into refrigerated and insulated vehicles. Choosing appropriate materials and structures can improve the insulation performance of the refrigerated truck, increase work efficiency, and reduce costs.

[0005] This utility model provides a fixed frame structure that effectively solves these problems, offering a fixed frame structure that is easy to install, has good heat insulation, long heat preservation time, and is easy to modify and upgrade. Utility Model Content
