Movable home with retractable structures

Abstract

A mobile house construction (1) is easy to move with strong mobility; (2) has a high folding ratio, providing a good living experience; (3) has a simple structure and is easy to drive; (4) permits for the entire device to be factory manufactured; and (5) provides a standardization of structure, thus reducing costs. The home construction includes a main body structure and a folding mechanism. The main body mechanism is the main load-bearing structure of the mobile house, which is connected to the folding mechanism. The main structure includes a floor, a water tank, an engine, a bathroom, a kitchen, a door, a window, a load-bearing column, a load-bearing beam, and the like, and can further include several pieces of furniture. The folding mechanism can expand the internal space of the mobile house, including the left side folding mechanism, the right-side folding mechanism and the top folding mechanism.
