[0001] The invention relates to the technical field of pickup truck cargo boxes, in particular to an expandable pickup truck modified cargo box. Background Art

[0002] As a versatile means of transportation, pickup trucks are widely used in commercial, agricultural and personal use. They not only carry the task of transporting goods, but also reflect the practicality and versatility of vehicles. During the use of pickup trucks, the function and design of the cargo box directly affect the loading and unloading efficiency and transportation safety of goods.

[0003] Existing pickup truck cargo boxes are usually not equipped with auxiliary lifting channels or devices. When heavy objects need to be loaded, the goods must be lifted and placed on the truck box by manpower, which not only increases labor intensity but also reduces loading and unloading efficiency. Secondly, existing pickup truck cargo boxes lack an effective cargo fixing mechanism. During the driving of the vehicle, the cargo is prone to shaking or even shifting due to inertia, which may not only cause damage to the cargo, but also affect the stability and driving safety of the vehicle. In addition, the existing pickup truck cargo boxes have limited space utilization and lack a reasonable partition design, making it impossible to classify and place cargo of different types or specifications, which is not only not conducive to searching and management, but may also cause mutual squeezing and damage between the cargo, reducing the efficiency and safety of cargo transportation.
