[0026] The auxiliary intelligent vehicle of the present application can perform intelligent walking through an intelligent walking mechanism, and the intelligent walking mechanism can be an existing technology, such as an auxiliary intelligent navigation system, which can navigate the walking, etc. The rear end of the frame 20 is connected to other devices through a connecting structure, and the other devices can be: a hand-push sweeper, a hand-push vacuum cleaner, a hand-push sprinkler, etc. The frame 20 is provided with a protective shell 1 and an anti-collision mechanism at the front end, so that when the auxiliary intelligent vehicle encounters obstacles during walking, it can be protected to avoid causing greater damage.

[0027] Furthermore, the anti-collision mechanism includes a buffer unit arranged on the surface of the protective shell 1 , and one end of the buffer unit protrudes from the protective shell 1 .
