Abstract: This paper presents a design scheme of vehicle mounted foldable camping house, which connects multiple folding units such as wall, floor, bed board and roof with each other by means of rotating pair and cylindrical sleeve ball joint, and drives the expansion and folding of each folding unit to exchange deformation through the driving device. When exchanging deformation, each folding unit changes along a single fixed path without interference point and dead point in the change process.It can be repeatedly and stably used in two states: unfolding and folding. When unfolding, it can form a large volume space surrounded by six sides . When folding, each folding unit can be closely attached into a bundle, and the small volume is convenient for vehicle movement, and its folding ratio can exceed 8.6 times. The supporting vehicle rack of the foldable room proposed in this paper can be used by various vehicle models, and the supporting small trailer and combined rack can easily form a field living camp.The folding trunk is combined into a trunk shell, which can easily transform an ordinary vehicle into a habitable self-propelled RV.
