Description

Intelligent case and bag of changeable action wheel interval

Technical Field

The invention belongs to the field of bags, and particularly relates to an intelligent bag capable of switching intervals of driving wheels.

Background

The case is an article which is often carried by people when people go out for travel. An existing luggage is usually pulled and walks by people, but sometimes the luggage is inconvenient to pull when being too much, an intelligent luggage capable of being automatically followed is developed for people, for example, patent 201510658109.9 discloses a drag-free automatic intelligent following luggage, so that the luggage is intelligently identified and automatically followed in flat areas such as airports and stations, even on roads, the two hands of a luggage owner are liberated, and many unexpected troubles in the journey are solved. However, when the suitcase is in an intelligent walking state, the suitcase is not supported by people, so that the suitcase has unstable gravity center and is easy to topple, especially on inclined or bumpy roads. For this reason, CN201510625909 discloses an intelligent following obstacle-surmounting suitcase, but the suitcase is placed upside down to keep stable, which not only occupies large space but also is inconvenient to switch between manual dragging and intelligent following modes. When people travel, the luggage case can be automatically followed only occasionally when needed, and the luggage case is mostly dragged manually, so that the luggage case is prevented from being lost or stolen. When people drag, the occupied area of the box body is required to be small so as to prevent the people or articles from being touched carelessly.
