Description

Technical Field

[0001] This utility model relates to the field of expandable housing technology, and in particular to a prefabricated liftable house. Background Technology

[0002] Portable homes can be quickly transported and deployed as needed. However, existing light steel frame houses use welded heavy steel for their load-bearing frames, with the central skeleton made of light steel filled with insulation materials such as rock wool. The sides of the light steel are waterproofed with breathable paper or OSB board, and then sealed with protective materials such as cement fiberboard. Because this structure is welded, the house space is fixed, and its height and dimensions cannot be expanded. Furthermore, the height and dimensions of this structure exceed the requirements for container shipping, resulting in high shipping costs. Existing houses that can fit into a standard 40-foot container have low interior heights, failing to meet relevant residential regulations (interior height > 2400mm, bathroom height > 2100mm), limiting their application scenarios and hindering widespread adoption. Therefore, existing housing technologies suffer from high transportation costs and low interior heights. Summary of the Invention

[0040] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.

[0041] This utility model discloses a prefabricated liftable house, such as Figures 1 to 3 As shown, the house includes a lower frame 1, an upper frame 2, and a propulsion device 3. A bathroom module and / or a kitchen module are integrated within the lower frame 1. Both the lower frame 1 and the upper frame 2 are composed of two opposing side frames 11, connected by multiple elongated connecting rods 12. The lower frame 1 contains multiple bottom connecting rods 13 parallel to the side frames 11, and these bottom connecting rods 13 are connected to the elongated connecting rods 12 on the bottom surface of the lower frame 1. 2. Connection is made; the upper frame 2 is provided with multiple top surface connecting rods 23 parallel to the side frame 11, and the top surface connecting rods 23 connect to the long strip connecting rods 12 on the top surface of the upper frame 2; the upper structural columns 24 around the upper frame 2 extend downward and are correspondingly inserted into the hollow cavities of the lower structural columns 14 around the lower frame 1, and the upper structural columns 24 can slide vertically within the hollow cavities; one or more of the propulsion devices 3 are disposed in the lower frame 1, and each of the... The support head of the propulsion device 3 supports the top connecting rod 23 and pushes the upper frame 2 to move vertically; the lower structural column 14 is provided with a through hole, and the upper structural column 24 is provided with one or more adjustment holes corresponding to the through hole; the pin 42 of the locking device 4 passes through both the through hole and one of the adjustment holes to lock the lower frame 1 and the upper frame 2 in the vertical direction; the top connecting rod 102 in the side frame 11 of the lower frame 1 is rotatably connected to a lower structural side plate 15 through the rotating mechanism 6; the long strip connecting rod 12 of the upper structural side plate 25 is rotatably connected to an upper structural side plate 25 through the rotating mechanism 6; the lower frame 1 is provided with multiple tensioning devices 5, and the ends of the cables 52 of the tensioning devices 5 are fixedly connected to a lower structural side plate 15 or an upper structural side plate 25; the tensioning devices 5 control the lower structural side plate 15 or the upper structural side plate 25 to flip by stretching the cables 52.

[0042] The upper frame 2 is positioned above the lower frame 1. The side frame 11 of the lower frame 1 consists of a bottom connecting rod 101, a top connecting rod 102, and two lower structural columns 14, and the side frame 11 of the lower frame 1 is rectangular. The side frame 11 of the upper frame 2 consists of a top connecting rod 102 and two upper structural columns 24, so the side frame 11 of the upper frame 2 is arch-shaped, meaning that the side frame 11 of the upper frame 2 does not have a bottom connecting rod 101. The upper structural columns 24 around the upper frame 2 are inserted into the hollow cavities of the lower structural columns 14. Therefore, the cross-sectional dimensions of the lower structural columns 14 are larger than the cross-sectional dimensions of the upper structural columns 24. The dimensions must be set to ensure that the upper structural columns 24 can be fully inserted into the hollow cavities of the lower structural columns 14 and slide smoothly. With the above structural setup, the lower frame 1 is fixed, and under the limiting effect of the lower structural column 14 on the upper structural column 24, the upper frame 2 can slide vertically relative to the lower frame 1, thereby realizing the adjustment of the building height.

[0043] When transportation is required, the upper frame 2 can be lowered to its lowest position, minimizing the overall size of the house. At this reduced size, it can fit into a 20-foot or 40-foot standard shipping container, which can be stacked, significantly reducing transportation costs. Furthermore, with the house reduced in size, there are no height or width restrictions, eliminating the need for traffic control applications and facilitating road transport while saving on costs. When unfolded for use, the upper frame 2 can be pushed upwards using the propulsion device 3, causing it to move vertically and increase the house's height. When the upper frame 2 slides to the designated position, the adjustment hole on the upper structural column 24 aligns with the through hole on the lower structural column 14. The pin 42 of the locking device 4 simultaneously penetrates both the aligned through hole and the adjustment hole, locking the position and preventing the upper frame 2 from descending. Then, the lower structural side panel 15 and the upper structural side panel 25 are flipped by the tensioning device 5. Under the driving force of the tensioning device 5 and their own gravity, the lower structural side panel 15 and the upper structural side panel 25 flip downwards to a vertical state. The house structure during the flipping process is as follows: Figure 1 As shown, the lower structural side panel 15 and the upper structural side panel 25, which are flipped to a vertical position, can protect the side of the building.

[0044] By pushing the upper frame 2 upwards, the internal height of the house can be significantly increased, thereby expanding the internal space. The upper frame 2 is pushed by the propulsion device 3 and locked in position by the locking device 4. The lower structural side panels 15 and the upper structural side panels 25 are flipped by the tensioning device 5. This enables automated expansion and contraction of the house, significantly reducing manual labor, improving deployment and assembly efficiency, and saving installation costs. External protective structures can also be installed on the sides of the lower frame 1 and the upper frame 2. These external protective structures, in addition to the structural walls 9, include doors, windows, walls, floors, ceilings, custom cabinets, and plumbing and electrical systems. Pre-assembling these structures within the lower frame 1 significantly reduces on-site installation work, thereby greatly reducing on-site installation labor costs and shortening installation time.

[0045] The entire upper frame (ceiling) of the house is raised using a lifting device, increasing the net height and meeting the relevant residential regulations (indoor net height > 2400mm, bathroom net height > 2100mm). The side walls of the gap are flipped out and raised using a stretching device and hinges. The connecting structure, interior and exterior finishes of the components for the height-lifting part of the house have been integrated. On-site, only the structural side panels need to be folded and nailed for fixation, which can greatly reduce local labor costs.

[0046] Through different structural designs, a variety of apartment layouts can be achieved (the interior layout can be varied), such as the following: Figure 12 As shown; Figure 12 This is merely a specific example of the interior layout of a house. In addition to the interior layout of the house shown in the attached diagram, other interior layouts of houses can be derived accordingly. The placement of external components such as terraces and stairs can be adjusted arbitrarily.

[0047] In a more specific embodiment, such as Figure 4 As shown, the propulsion device 3 includes a bracket 31, a drive cylinder 32, a push rod 33, a guide post 34, and a support head 35. The bracket 31 has a bracket 31 fixing plate at its top, the push rod 33 passes through the bracket 31 fixing plate, and the guide post 34 is arranged parallel to the push rod 33. One end of the guide post 34 is fixedly connected to the bottom surface of the bracket 31 fixing plate, and the other end is fixedly connected to the drive cylinder 32. The lower end of the push rod 33 is connected to the drive shaft of the drive cylinder 32. The upper end of the push rod 33 is fixedly connected to the support head 35. Specifically, the propulsion device 3 also includes multiple anti-slip rollers 36 disposed at the bottom of the bracket 31.

[0048] To maintain the stability of the propulsion device 3 during operation, a support bracket 31 can be installed for support, specifically a triangular support bracket 31. A support bracket 31 fixing plate is installed at the top of the support bracket 31, and a push rod 33 passes through the support bracket 31 fixing plate. A guide post 34 is used for guidance and to fix the drive cylinder 32. The drive shaft of the drive cylinder 32 can drive the push rod 33 to slide vertically along the guide post 34. The upper end of the push rod 33 is fixedly connected to a support head, so when the push rod 33 moves vertically, it can be supported by the support head and push the upper frame 2 to move vertically. To further improve the stability of the propulsion device 3 during operation, multiple anti-slip rollers 36 can also be installed at the bottom of the support bracket 31; such as... Figure 4 As shown, in this application, the support 31 is set as a triangular support 31, and a corresponding anti-slip roller 36 is set under each support leg of the support 31. The specific application of the propulsion device 3 is as follows. Figure 5 As shown.

[0049] To enhance user convenience, a wireless signal receiver can be installed inside the propulsion device 3. The wireless signal receiver is electrically connected to the drive cylinder 32, allowing the user to send wireless control signals to the wireless signal receiver via a terminal device. The wireless signal receiver then controls the drive cylinder 32 to operate according to the wireless control signals.

[0050] In a more specific embodiment, the locking device 4 includes a locking drive mechanism, a housing 41, and a pin 42; the locking drive mechanism is disposed within the housing 41, and the pin 42 extends outward from the inside of the housing 41, with its end fixedly connected to the locking drive mechanism; the pin 42 extends or retracts under the drive of the locking drive mechanism. The locking device 4 also includes a wireless locking signal receiver disposed inside or outside the housing 41, and the wireless locking signal receiver is electrically connected to the locking drive mechanism.

[0051] like Figure 6 and Figure 8 As shown, a locking device 4 is provided on the side of each lower structural column 14. The locking device 4 can be composed of a locking drive mechanism, a housing 41, and a pin 42. The locking drive mechanism can drive the pin 42 to extend or retract. When the house needs to be retracted, the locking drive mechanism can drive the pin 42 to retract, thereby releasing the pin 42 from locking the upper frame 2, allowing the upper frame 2 to slide vertically freely. When the house needs to be extended, the upper frame 2 can be slid to a specific position, and the locking drive mechanism can drive the pin 42 to extend, at which point the pin 42 can lock the upper frame 2.

[0052] Furthermore, to improve the convenience of controlling the locking device 4, a wireless locking signal receiver can be installed inside the locking device 4. Users can send control signals to the wireless locking signal receiver through terminal devices (such as mobile phones or tablets). The wireless locking signal receiver controls the locking drive mechanism to work according to the received control signals. That is, the locking drive mechanism controls the pin 42 to extend or retract according to the control signals.

[0053] In a more specific embodiment, such as Figure 7 and Figure 9 As shown, the tensioning device 5 includes a tensioning drive mechanism, a device housing 51, and a tension cable 52. The tensioning drive mechanism is disposed within the device housing 51, and its rotating shaft extends outward from the inside of the device housing 51. The end of the tension cable 52 is fixedly connected to the rotating shaft. The tensioning device 5 also includes a wireless tensioning signal receiver 53 disposed inside or outside the device housing 51, and the wireless tensioning signal receiver is electrically connected to the tensioning drive mechanism.

[0054] A tensioning device 5 is installed above each lower structural side panel 15 and upper structural side panel 25. The tensioning device 5 drives the tension cable 52 to loosen or tighten through a tensioning drive mechanism. When the tension cable 52 is tightened and shortened, the side panel can be flipped upward; when the tension cable 52 is loosened, the side panel can be flipped downward under the action of gravity. Furthermore, a wireless tensioning signal receiver can be installed in the device housing 51 to send control signals to the tensioning device 5 through a terminal device, thereby improving the convenience of control.

[0055] In a more specific embodiment, such as Figure 10 As shown, the rotating mechanism 6 is a hinge; multiple hinges are provided between the top connecting rod 102 in the side frame 11 of the lower frame 1 and the side edge of the lower structural side plate 15, and the lower structural side plate 15 flips around the lateral axis of the hinge; multiple hinges are provided between the long strip connecting rod 12 of the upper structural side plate 25 and the side edge of the upper structural side plate 25, and the upper structural side plate 25 flips around the lateral axis of the hinge. Further, as... Figure 10 and Figure 11 As shown, a diagonal brace 7 is provided between the top of the lower structural column 14 in the lower frame 1 and the connected elongated connecting rod 12; a diagonal brace 7 is also provided between the top of the lower structural column 14 and the connected top connecting rod 102. By providing the diagonal brace 7, the structural strength of the lower frame 1 is improved, and the stability of the support for the upper frame 2 is enhanced.

[0056] like Figure 5As shown, in a more specific embodiment, a fixing through hole 8 is provided at the top corner of the bottom surface of the lower frame 1; the fixing through hole 8 is adapted to the fixing post. With fixing through holes 8 provided at the top corner of the bottom surface of the lower frame 1, and all fixing through holes 8 facing outwards, each top corner of the bottom surface of the lower frame 1 has three fixing through holes 8, each facing a different direction; the fixing through holes 8 are adapted to the fixing posts provided on the container transfer plate, so that the fixing posts can extend into the fixing through holes 8 to limit and fix the pull-out house, thereby facilitating the direct transportation of the pull-out house as a containerized component and improving the transportation efficiency of the house.

[0057] This utility model discloses a prefabricated lifting house, which includes a lower frame, an upper frame, and a propulsion device. A bathroom module and / or a kitchen module are integrated within the lower frame. Both the upper and lower frames consist of two opposing side frames connected by multiple elongated connecting rods. Upper structural columns around the upper frame extend downwards and are inserted into the hollow cavities of the lower structural columns around the lower frame. The top connecting rods in the side frames of the lower frame are rotatably connected to a lower structural side plate via a rotating mechanism. The elongated connecting rods of the upper structural side plates are also rotatably connected to an upper structural side plate via a rotating mechanism. The house moves vertically by pushing the upper frame with the propulsion device. By flipping the lower and upper structural side plates, the internal height of the house can be increased, expanding the usable space. When retracted, the house can accommodate container transportation, eliminating the need for strict road transport conditions and significantly reducing transportation costs.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.
