Description

Technical Field

[0001] The invention relates to a luggage case, in particular to an electric luggage case. Background Art

[0002] Electric luggage can not only hold items, but also move by electric wheels, which is convenient for users to push or ride. In order to control the direction of the electric wheels, existing electric luggage will be equipped with a steering handle on the steering tube of the electric wheels. However, in actual application, if the steering handle is small, it is not easy to control the direction. If the steering handle is too large, it is easy to exceed the width of the luggage, which is not conducive to storing and hiding the steering handle. In addition, existing electric luggage generally uses a switch device on the steering handle to control the start and stop state of the electric wheel. While using the steering handle to control the direction, the user also needs to control the start and stop state of the electric wheel, which results in more hand control movements, increased control difficulty, and poor user experience.
