2. Description of Prior Art and Related Information

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.

The need for housing is an important part of human life, so optimizing people's living environment and quality of living has long been a pursuit of the housing industry. Traditional houses are located on the ground, in the form of villas or high-rise structures, with a stable structure and a large space. However, once built, it is impossible to change the location, and the construction period is long. Recreational Vehicles (RVs) are mobile and a good choice for going out to play and camping, but the width restriction of the body leads to a small interior space and low comfort when living.

The traditional villa construction process requires on-site fabrication and installation for the most structures and the construction cannot be prefabricated or has a low degree of prefabrication, resulting in a long construction cycle. The construction process requires professional construction teams for construction, which will incur high labor cost. As the house type is related to the size of the land, the house type needs to be changed or even redesigned for houses with different land sizes. Since there is no standardization of house types for houses with different lot sizes, each time a house is built, and redesigned by professionals.

In view of the foregoing, there is a need for a mobile house that overcomes the limitations of conventional mobile houses while providing a safe and comfortable living space.

SUMMARY OF THE INVENTION

Broadly, embodiments of the present invention provide an enclosed habitable house with multiple expandable mechanisms, including a main body mechanism, a roof system, a wall system and a bottom drive mechanism. The main body mechanism is connected with other elements for the framework of the structure and plays the role of structural support. The main body includes the main body frame and the articulation mechanisms. The roof system is symmetrical on both sides of the main body and installed on the upper part of thereof. The roof system includes two foldable sloped roofs and four foldable roof supports. The wall mechanism is symmetrically distributed on both sides of the main body and includes the outer wall system, the side wall system and the rotation mechanism. A bottom driving mechanism is used for the unfolding of the wall system and includes four sets of retractable pushing mechanisms. The front and rear walls can unfold from the sides of the main body during expansion of the structure.

FIG. 1 shows a schematic view of the foldable home 100 in the retracted state. The main body 102 is the main structural support part of the foldable home 100 with the roof system 101 installed above it. Wall system 103 is connected to the roof system 101, and the wall system 103 is hinged to the main body 102. A bottom driving mechanism 104 is installed at the bottom of the main body 102 is connected to the wall system 103 for retracting the wall system 103, as discussed below.

FIGS. 2A and 2B show a detailed view of the roof system 101. FIG. 3 shows a schematic view of the foldable home 100 in a half-expanded state. FIG. 4 is a sectional view of the foldable home 100 in the half-expanded state. Roof system 101 includes two foldable sloped roofs 1011 and four foldable roof supports 1012. Foldable sloped roofs 1011 include a plurality of roof modules 1013 that stack atop each other and also nest within a main body sloped roof section 1014. FIG. 3 illustrates three parts of the plurality of roof modules 1013 as an example.

As shown in FIG. 2B, roof module 207 is main body sloped roof section 1014 and is mutually fixed with the main body 102, roof modules 204, 205, 206 are nested in layers and will slide relatively during the unfolding process. The roof module 204 and the outer wall 306 are fixed to each other, and the roof module 204 will make the same movement when the outer wall 306 is unfolded outward. The roof module 204 will drive the roof module 205, and the roof module 205 will drive the roof module 206. The roof support mechanism 1012 helps the roof module slide and provides support for each of the plurality of roof modules 1013, including a support module 201, a support module 202 and a support module 203. The support module 201 provides support for the roof module 207, which is fixed to each other with the main body 102. The support module 202 is in the outermost layer of the roof support mechanism, and plays the role of protection and support for other roof support modules. The roof support modules are nested structures. The roof support module 202 slides within the roof support module 201 and is fixed with the roof module 206 to support the roof module 206. The roof support module 203 slides within the roof support module 202 and is fixed with the roof module 205 to support it. Since the roof module 204 is of equal width with the outer wall 306, the wall system 103 already provides support for the roof module 204, so there is no need for additional roof support module to provide assistance to the roof module 204.

When the home 100 is being unfolded, the bottom drive mechanism 104 pushes in the direction of the arrows 1046 in FIG. 3. The bottom drive mechanism 104 includes, for example, four sets of retractable drive rods 1042, 1043, 1044, the end 1045 of an outermost one of the drive rods (drive rod 1044) can be secured to the corners 3061 of the outer wall 306.

As seen in FIG. 4, the wall system 103 includes two outer walls 306 and four side wall systems 1031, each side wall system 1031 includes two side wall blocks 301, a pivoting attachment 304 with the main body 102, a relative rotation mechanism 302 between the two side wall modules 301 and a sealing and connecting mechanism 303 for providing a pivoting and sealed connection between the side wall modules 301 and outer wall 306. A front door 305 may be provided in the front of the main body 102 to provide access inside the home 100.

FIG. 5 is a top section view of the foldable home in the half-expanded state. As can be seen in FIG. 5, the main body 102 can include a front wall 1021, a rear wall 1022 and sides 1023 that span between the front wall 1021 and the rear wall 1022. In should be understood that the sides 1023 of the main body 102 may not be structurally present such that, when the home 100 is fully expanded, the main body 102 may be completely open to each expansion structure 1024. For example, the sides 1023 shown in FIG. 5 may be the folded floor modules 706 (see FIGS. 8 through 10). In this embodiment, the sides 1023 of the main body 102 may simply be a space between front and rear corners of the main body 102. In some embodiments, the sites 1023 may be partial walls, or walls with doors or other openings to permit egress between the main body 102 and the expansion structures 1024.

FIG. 6 is the schematic view of the foldable home in the fully expanded state except the expansion of the floors, as described below. Due to the geometric design of each roof module being of the same slope, with the lowest point of the previous roof module being the same height as the highest point of the following roof module, both the upper surface 501 and the side surfaces 502 of the sloped roof system 101 are each an integral and planar when fully expanded. FIG. 7 is the front view of the foldable home 100 in the fully expanded state except floors.

FIG. 8 is the front section view of the foldable home 100 in the fully expanded state except floors. The contact portions 702, 703 between the plurality of roof modules 1013 (and the contact portion 701 between the main body roof portion 1014 and the first one of the plurality of roof modules 1013) all have a portion of the smaller roof module (the one distal the main body 102) remaining on the inside of the larger roof module, and the load transfer and sealing functions are achieved by this structure.

The floor modules 706 are hinged at a pivot point 801 to the main body 102 and are connected by hydraulic rods 704 inside the foldable home 100. Each floor module 706 can be controlled by two hydraulic rods 704 with connection points 705 that allow relative rotation of both. The floor modules 706 will rotate relative to the main body 102 in the direction of the arrow 707 in FIG. 9, controlled by the hydraulic rods 704. FIG. 10 shows the floor modules 706 in their fully expanded state.
