[0002] At present, unmanned logistics technology is developing rapidly. A large amount of logistics sorting and transportation have begun to be completed by robots or unmanned vehicles. Through their internally integrated unmanned driving kits, they can complete functions such as driving along planned routes and autonomously avoiding obstacles. Although it can reduce the participation of personnel to a certain extent, the automatic loading and unloading of goods is still a relatively difficult technology to achieve.

[0003] On the logistics production line, it is usually necessary to unload the material boxes on the unmanned vehicle onto the automatic production line. The existing vehicle unloading solutions and devices are mainly divided into two categories: auxiliary loading and unloading devices and automatic loading and unloading devices.
