Therefore, on the basis of keeping the existing automobile type and carrying function, the increase of living, rest and working function areas of the automobile has wide market application prospect.

The folding structure is a structure which is unfolded when in use and folded when not in use. The folding rod or plate has the advantages that the folding rod or plate can be repeatedly and stably used in an unfolding or folding state, and the folded rod or plate is tightly bundled, so that the folding rod or plate is small in size and convenient to transport and store. In recent years, folding structures are widely applied in the fields of life, aviation and the like, certain development is achieved on structural forms, products designed in various folding modes such as flat, axle center, plug-in, sleeve type, roll type and the like are produced, the folding structures form the classification of rod system units and plate system units, and the stable modes after unfolding and forming can be divided into structural self-locking modes and externally-added constraint locking modes, and rigid folding structures and flexible folding structures are distinguished.

The present folding structures mainly relate to folding on flat surfaces and curved surfaces, such as folding doors, folding antennas, solar sailboards and the like, while the folding in terms of volume mainly relates to the folding in terms of volume: 1. the non-rigid deformation is required, so that the deformation process of the exchange from the unfolded state to the folded state is not easy to control and is not easy to repeatedly stabilize in the unfolded or folded state. 2. The folding device is characterized in that a plurality of folding modes are needed, and the multi-layer multi-node subsection driving is adopted, so that the deformation process from unfolding to folding state exchange is needed to be driven for multiple times, the unfolding and folding exchange operation is complex, the space structure is complex, and the folding and unfolding of the space convenient and stable are difficult to realize. Meanwhile, the folding in the aspect of volume is difficult to completely fold into a compact bundle shape after being folded because all folding surfaces are easy to interfere with each other, and the ideal folding and unfolding ratio is difficult to achieve.
