[0002] In recent years, artificial intelligence and autonomous driving have developed rapidly in my country, successfully driving a series of upstream and downstream enterprises to diversify their development in the direction of new quality productivity. Various enterprises have transformed themselves to catch the first train of new quality productivity, developing their own intelligent unmanned equipment such as drones, unmanned cars, unmanned sightseeing vehicles, and unmanned logistics vehicles. Currently, the market response to intelligent unmanned logistics vehicles is good, but production and sales are limited by various local policies, regulations, and road rights. In order to control R&D investment and reduce R&D and production costs, enterprises generally only invest in semi-automatic or manual assembly lines and manual testing stations to meet production, transportation, and testing requirements. However, the assembly process of intelligent unmanned logistics vehicle chassis requires multiple stations and processes for assembly, transportation, reassembly, and retransport until the chassis assembly is complete. Therefore, there is an urgent need for a chassis transportation device that can meet the needs of various models of unmanned logistics vehicles. Utility Model Content
