Field of the Invention

The present invention relates to a mobility unit capable of coupling a vehicle and another vehicle and connecting internal spaces of the vehicles to each other or isolating the internal spaces of the vehicles from each other.

Description of Related Art

With the development of electric vehicles, a subminiature mobility has been suggested. The subminiature mobility is configured in a form of a single-seated mobility or a two-seated mobility. Due to the limitations in the engine capacity of an electric vehicle, the subminiature mobility is expected to be mainly used for short distances, for example, for commuting or grocery shopping. Depending on the circumstances, however, the situation may occur in which it is necessary to drive the subminiature mobility a long distance.

In the case in which the subminiature mobility is driven a long distance, various burdens, such as a battery-related problem or fatigue due to long-distance driving, may occur. In the case in which the subminiature mobility is coupled to another subminiature mobility in the present situation, it is possible to share batteries of the mobilities and select the driver of the mobilities. For these reasons, there is necessity for aggregate travel.

To date, however, the hardware of the subminiature mobility has been intensively developed, but no concept of aggregate travel or coupled travel has been suggested.

The information disclosed in this Background of the present invention section is only for enhancement of understanding of the general background of the present invention and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
