Description

Technical Field

[0001] The present invention relates to the technical field of vehicle cargo boxes, in particular to a telescopic side-expandable vehicle cargo box. Background Art

[0002] A vehicle cargo box is a cargo device installed on a vehicle for transporting goods, tools or equipment. With the development of the industry, cargo boxes have also developed various structures according to their functions. For example, the wingspan cargo box, which is widely used now, is a special vehicle cargo box design. Its side or top doors can be unfolded upward like wings. On the one hand, it can realize fast loading and unloading of goods, and on the other hand, it can also be used as a stall. The side of the wingspan cargo box can be opened, making the car itself a stall site for sales, consulting services, etc. For example, the authorization announcement number C Chinese invention patent N118082665A discloses a vehicle-mounted outward-expanding vending stand device and a vending truck. The vehicle-mounted outward-expanding vending stand device includes a vehicle body and a vending stand assembly. The vehicle body is provided with a storage space. The vending stand assembly includes a vending stand frame and a vending cabinet. The vending stand frame is slidably mounted on the vehicle body via a sliding support mechanism, so that the vending stand assembly can be extended or retracted relative to the vehicle body in a first direction. When the vending stand assembly is in a retracted state, it retracts into the storage space. However, this traditional wing-span cargo box has the following disadvantages:

[0003] This type of cargo box is subject to restrictions on vehicles and road regulations, and its size is also limited, resulting in a smaller space.
