Description

Technical Field

[0001] This invention belongs to the field of mobile housing technology, and specifically relates to a folding house. Background Technology

[0002] Traditional mobile folding houses are folded as a whole and unfolded on-site. They are generally small buildings with only one room, which often cannot meet the needs of use. Later, multi-span folding houses appeared. Their basic structure includes a small fixed compartment and at least one extended compartment. The extended compartment can be folded into the fixed compartment. For example, Chinese patent document CN106759919A has a middle span structure. Based on the middle span structure, there are foldable left and right span structures. The left and right span structures include a roof frame, front wall frame, and rear wall frame, which are all hinged to the middle span structure. The side wall frame is an independent structure. The folding mechanism of this scheme is a building frame system. After the frame system is fixed, the roof decorative panels need to be installed.

[0003] Existing technologies, such as Chinese patent document CN101769009B, provide a folding mobile house assembled from panels, in which one end of each panel on each side of the expandable room is rotatably connected to the wall between the core, thereby enabling the relative folding of the house.

[0004] The shortcomings of existing technologies are as follows: 1) Folding mechanisms are mostly frame systems. After the main structure of the house is fixed, wall panels and roof panels need to be laid piece by piece, which is inconvenient to construct and slow to install as a whole; 2) Fixing the extended roof panel requires high-altitude installation, which is dangerous and inefficient; 3) The free ends of each side wall are separated, requiring many fasteners for fixation, making on-site installation cumbersome and time-consuming; 4) The unfolding and folding of the extended compartment depends on manual operation, which lacks automation and stability; 5) Folding panels are usually connected by simple double-wing hinges, which are misaligned at the included angles, resulting in insufficient load-bearing capacity, easy loosening, and affecting the overall sealing and load-bearing performance of the house. Summary of the Invention

[0005] To address the above problems, this invention provides a foldable house with fast installation speed.

[0006] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: A folding house includes a main compartment, which consists of a base, a roof panel, a front wall, and a rear wall fixed together. An extension compartment, capable of being folded or unfolded relative to the main compartment, is provided on the left and / or right sides of the main compartment. The extension compartment includes: An extended top plate is rotatably connected to the roof panel at its upper end and is a free end at its lower end. An extended base plate, one end of which is rotatably connected to the base, and the other end is a free end; The gable wall is slidably connected at its upper end to the extended top plate and at its lower end to the extended bottom plate, and it can reciprocate relative to the mother compartment by moving closer to or further away from it. The extended sidewalls are provided in two parts, which are rotatably connected to the front wall and the rear wall respectively, while the other side is a free end.

[0007] Compared with the prior art, the present invention employing the above structure has the following advantages: 1) This solution utilizes the gable wall to drive the installation of the extended roof panel, solving the problem of high-altitude work required for the roof panel; 2) The folding modules in this solution integrate the house frame and walls into one unit, eliminating the need for separate frame folding. The subsequent laying of wall panels and the extension of the house complete the overall installation in one go, greatly improving the installation speed.

[0008] As a preferred option, a further technical solution to the above structure is: The lower end of the gable wall is connected to the extended base plate via a first sliding module. The first sliding module consists of a fixed seat and a pulley. The fixed seat is T-shaped, with its horizontal part fixed to the surface of the gable wall and the pulley installed at the outer end of its vertical part. The pulley is installed in a slide rail, which is fixedly connected to the extended base plate. The upper end of the gable wall is connected to the extended top plate via a second sliding module. The second sliding module consists of a fixed plate, a movable plate, and a pulley. The fixed plate is fixed to the surface of the gable wall. One end of the movable plate is connected to the fixed plate via a pin, and the other end is equipped with the pulley, which is installed in a slide rail, which is fixedly connected to the extended top plate.

[0009] The beneficial effects obtained from the above features are: this embodiment allows the gable wall to slide inward and outward, while maintaining its connection with the top and bottom plates during sliding, effectively driving the top plate to unfold and facilitating installation and fixing.

[0010] At least one of the rotating connections is achieved by installing a hinge module, which includes: a first connecting plate, comprising a flat plate with bolt holes on its surface, and a bushing fixedly connected to the lower side of the flat plate; a rotating block, which is a U-shaped plate with a bushing fixedly connected to its upper end and a free end at its lower end; a rotating shaft, installed inside the bushing, with limit blocks installed at both ends to prevent the bushing from detaching; and a second connecting plate, which is an L-shaped plate with bolt holes on its surface and is fixedly connected to the lower end of the rotating block.

[0011] The beneficial effects obtained from the above features are as follows: The hinge module provided in this embodiment enables the ends of the two walls to rotate relative to each other, and the two wall sides can be aligned in both the initial and final states of rotation. Compared with conventional hinge connections, this structure does not produce wall misalignment, is aesthetically pleasing, has a compact structure, and better load-bearing performance.

[0012] The gable wall is symmetrically equipped with telescopic support modules on both sides. The other end of the telescopic support module is connected to the front wall and the rear wall. The telescopic support module includes: a sliding groove, which is divided into a fixed sliding groove and a movable sliding groove. The two have the same structure. The fixed sliding groove is fixed to the surface of the front wall or the rear wall; the movable sliding groove is fixed to the surface of the gable wall; and a scissor-type telescopic mechanism, which is composed of several connecting rods hinged together. Each end of the mechanism has two connecting rod ends. One connecting rod end is hinged to a movable contact block, and the other connecting rod end is hinged to a fixed contact block. The fixed contact block is fixed to the upper end of the sliding groove, and the movable contact block is slidably installed inside the sliding groove.

[0013] The beneficial effects obtained from the above features are: the scissor-type telescopic mechanism supports the movement of the gable wall, ensures the smooth movement of the gable wall, and improves the overall stability of the building.

[0014] An electric actuator is provided on the lower side of the moving contact block at one end of the scissor-type telescopic mechanism, and the piston end of the electric actuator is connected to the lower side of the moving contact block.

[0015] The beneficial effects obtained from the above features are: by using an electrically driven telescopic support module, the movement of the gable wall can be controlled, saving manpower and realizing the automated extension and retraction of the house.

[0016] Hydraulic telescopic rods are symmetrically installed on both sides of the extended top plate and the extended bottom plate. One end of the hydraulic telescopic rod is hinged to the side wall of the extended top plate or the extended bottom plate, and the other end is hinged to the front wall or the rear wall.

[0017] The beneficial effects obtained from the above features are: the rotation of the extended roof and extended floor is controlled by hydraulic telescopic rods, realizing the automated extension and retraction of the house.

[0018] A stop plate is provided at the end of the slide rail to prevent the pulley from coming off.

[0019] The height of the gable wall is lower than the height of the mother chamber, causing the outer end of the extended top plate to tilt downwards, with the tilt angle of the extended top plate being 30° to 45°.

[0020] The beneficial effects obtained from the above features are: the inclined extended top plate facilitates the linkage of its gable walls; the inclined top plate avoids the accumulation of debris and is easy to clean.

[0021] In the retracted state, the extended sidewall is located on the side of the mother compartment, the gable wall is located outside the extended sidewall, the extended top plate is located outside the gable wall, and the extended bottom plate is located outside the extended top plate. The outer end of the extended bottom plate is connected to the extended top plate by a buckle or hook.

[0022] The beneficial effects obtained from the above features are as follows: This embodiment specifically defines the distribution structure of each block of the expansion compartment. This distribution structure allows the side panels to extend sequentially, which is convenient for installation. The later-extended structure provides support and reinforcement to the earlier-extended structure, ensuring the stability of the overall house. The fixing method of the expansion base plate can prevent the structure from collapsing when it is closed.

[0023] The sliding rails are embedded inside the extended top and bottom plates, so that the sliding rails do not take up interior space, the structure is more compact, and the overall house is more beautiful.

[0024] The beneficial effects of this invention are: 1) Quick installation, no need for working at heights: Through the sliding connection between the gable wall and the extended top and bottom plates, and the reciprocating movement of the gable wall, the extended top plate can be automatically positioned. No manual operation of the extended top plate at height is required, reducing installation risks. Simultaneously, the house frame and walls unfold synchronously, completing the overall installation in one go, significantly improving construction speed.

[0025] 2) Compact structure and high space utilization: The sliding rails are embedded inside the extended top and bottom plates, without occupying indoor space, and the overall appearance is flat and beautiful. The height of the gable wall is lower than that of the mother compartment, so that the extended top plate naturally forms a 30° to 45° inclination, which facilitates drainage, prevents dust accumulation, and is also conducive to gable wall linkage.

[0026] 3) Reliable connection and good load-bearing capacity: A special hinge module (first connecting plate, rotating block, rotating shaft, second connecting plate) is used to replace conventional hinges. Both connecting surfaces are aligned at the start and end of rotation, with no misalignment. The structure is compact and has strong load-bearing capacity. The sliding connection uses pulleys and rails for smooth movement, and a stop plate at the end prevents it from coming off.

[0027] 4) High degree of automation and labor-saving operation: Equipped with an electric actuator to drive a scissor-type telescopic mechanism to control the movement of the gable wall; or driven by a hydraulic telescopic rod to rotate the extension top and extension bottom plates. Users can complete the deployment or retrieval of the extension compartment with just one button operation, saving manpower and making it suitable for rapid deployment scenarios such as emergency rescue and field operations.

[0028] 5) Good overall stability and reliable locking: The extended side walls, gable walls, extended top plate, and extended bottom plate are distributed sequentially, with the later-deployed components providing support and reinforcement for the earlier-deployed components. The outer end of the extended bottom plate is connected to the extended top plate via buckles or hooks, which can prevent structural collapse when the structure is retracted and ensure overall rigidity when deployed.

[0029] 6) Highly adaptable, can be expanded on one or both sides: Expansion compartments can be set on the left and / or right sides of the main compartment. Users can flexibly choose the direction and number of expansions according to site requirements to meet different living or working space requirements. Attached Figure Description

[0032] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0033] See Figures 1 to 14 This invention provides a folding house, including a main compartment 1, which consists of a base 102, a roof panel 101, a front wall 103, and a rear wall 104 fixedly connected together. An extension compartment 2, capable of being folded or unfolded relative to the main compartment 1, is provided on the left and / or right sides of the main compartment 1. The extension compartment 2 includes: The extended top plate 201 is rotatably connected to the roof plate 101 at its upper end and is a free end at its lower end. The extension base plate 202 has one end rotatably connected to the base 102, and the other end is a free end; The gable wall 203 is slidably connected at its upper end to the extended top plate 201 and at its lower end to the extended bottom plate 202, and it can reciprocate relative to the mother compartment 1 by approaching or moving away. There are two extended side walls 204, which are rotatably connected to the front wall 103 and the rear wall 104 respectively, and the other side is a free end.

[0034] As a preferred option, the lower end of the gable wall 203 is connected to the extended base plate 202 via a first sliding module 5. The first sliding module 5 consists of a fixed seat and a pulley 6. The fixed seat is T-shaped, with its horizontal part 501 fixed to the surface of the gable wall 203 and the pulley 6 installed at the outer end of its vertical part 502. The pulley 6 is installed in the slide rail 8, and the slide rail 8 is fixedly connected to the extended base plate 202.

[0035] As a preferred option, the upper end of the gable wall 203 is connected to the extended top plate 201 via a second sliding module 7. The second sliding module 7 consists of a fixed plate 701, a movable plate 703, and a pulley 6. One end of the movable plate 703 is connected to the fixed plate 701 via a pin 704, and the other end is fitted with the pulley 6, which is mounted in a slide rail 8. Specifically, the fixed plate 701 consists of a fixed lug and a connecting lug 702 vertically fixed to the surface of the fixed lug. The fixed lug is fixed to the surface of the gable wall 203, and the end of the connecting lug 702 has a hole for mounting the pin 704. The slide rail 8 is fixedly connected to the extended top plate 201.

[0036] The lower end of the gable wall 203 is supported inside the slide rail 8 of the base 102 by the first sliding module 5. The pulley 6 reduces friction when the gable wall 203 moves, and the pulley 6 always stays inside the slide rail 8. A section of slide rail 8 is also provided on the outer edge of the base 102, so that during the folding operation, the first sliding module 5 can directly enter the slide rail 8 of the base 102 from the slide rail 8 of the extended base plate 202, thus folding it up smoothly. The upper end of the gable wall 203 is connected to the extended top plate 201 by the second sliding module 7. When the gable wall 203 slides outward, it can drive the extended top plate 201 to unfold during the sliding process. The gable wall 203 completes the support of the extended top plate 201 at the same time as it is in place, which facilitates the subsequent connection and fixation of the extended top plate 201 and the extended side wall 204, and facilitates the overall installation.

[0037] As a preferred option, the rotational connection is achieved by installing a hinge module 9, which includes: a first connecting plate 901, comprising a flat plate with bolt holes on its surface, and a bushing fixedly connected to the lower side of the flat plate; a rotating block 902, which is a U-shaped plate with a bushing fixedly connected to its upper end and a free end at its lower end; a rotating shaft 903, installed inside the bushing, with limit blocks installed at both ends to prevent the bushing from detaching; and a second connecting plate 904, which is an L-shaped plate with bolt holes on its surface and is fixedly connected to the lower end of the rotating block 902.

[0038] More specifically, the bushing is fixed to the lower side of the first connecting plate 901 by a short connecting rib. The distance between the connecting rib and the left end of the first connecting plate 901 is L1, and the distance from the right end is L2, where L1 is greater than L2. For the U-shaped rotating block 902, the width of the shaft end wing plate is less than L1 but greater than L2, and the width of the web plate is greater than L2. The free end wing plate only needs to accommodate 1-2 rows of bolt holes. The width of the two side plates of the L-shaped second connecting plate 904 should be less than the wall thickness. The rotating block 902 of this structure rotates around the first connecting plate 901 at an angle ranging from 180° to 225°. After the second connecting plate 904 is installed at the free end of the rotating block 902, the rotation angle is between 90° and 100°.

[0039] The hinge module 9 provided in this embodiment enables the ends of the two walls to rotate relative to each other, and the two wall sides can be aligned in both the initial and final states of rotation. Compared with conventional hinge connections, this structure does not cause wall misalignment, is aesthetically pleasing, has a compact structure, and better load-bearing performance.

[0040] See Figure 11 , Figure 12 Before the hinge module 9 is installed, a prefabricated window 1021 should be reserved on the end face of the base 102 or the roof panel 101. The prefabricated window 1021 is opened on the side of the reinforcing beam at the edge of the base 102 and the roof panel 101. The end faces of the extended base plate 202, the extended top plate 201 and the extended side wall 204 should be reserved with prefabricated slots 2021. The prefabricated slots 2021 are opened on the side of the reinforcing beam of the extended base plate 202 and the extended top plate 201. For example, when used to connect the extended top plate 201 and the roof panel 101, the first connecting plate 901 is fixed to the lower side of the inner wall of the reinforcing beam of the roof panel 101. The rotating block 902 is set inside the prefabricated window 1021 and can rotate out of the prefabricated window 1021. One side of the second connecting plate 904 is fixed to the rotating block 902, and the other side extends out of the prefabricated slot 2021 and is fixed to the inner wall of the reinforcing beam of the extended top plate 201.

[0041] In addition, the extended side wall 204 of this solution adopts a hinged folding structure, which can also be connected to the inner side of the front wall 103 or the rear wall 104 using traditional double-wing hinges.

[0042] As a preferred option, telescopic support modules 4 are symmetrically arranged on both sides of the gable wall 203, and the other end of the telescopic support module 4 is connected to the front wall 103 and the rear wall 104. The telescopic support module 4 includes: The slide 401 is divided into a fixed slide 401 and a movable slide 401. The two have the same structure. The fixed slide 401 is fixed to the surface of the front wall 103 or the rear wall 104; the movable slide 401 is fixed to the surface of the gable wall 203. The scissor-type telescopic mechanism 402 is composed of several hinged links. Each end has two connecting rod ends. One connecting rod end is hinged to a movable contact block 404, and the other connecting rod end is hinged to a fixed contact block 403. The fixed contact block 403 is fixed to the upper end of the slide groove 401, while the movable contact block 404 is slidably installed inside the slide groove 401. The scissor-type telescopic mechanism 402 supports the movement of the gable wall 203, ensuring its smooth movement and improving the overall stability of the building.

[0043] The slide groove 401 can be made of channel steel, with upper and lower through grooves for the movable contact block 404 to slide arbitrarily; alternatively, the slide groove 401 can be made of square steel tube, with sliding holes 405 provided on the surface corresponding to the movable contact block 404 and its moving range. Square steel tube has high strength and is not easily deformed. A limiting ear 406 is provided on the upper side of the movable contact block 404, and the limiting ear 406 is fixedly connected to the surface of the slide groove 401.

[0044] Furthermore, an electric actuator 407 is provided on the lower side of the movable contact block 404 at one end of the scissor-type telescopic mechanism 402, and the piston end of the electric actuator 407 is connected to the lower side of the movable contact block 404. In order to fix the electric actuator 407, a support base 408 is fixedly connected to the bottom of the slide groove 401. The electric actuator 407 is installed parallel to the slide groove 401, with its lower end set in the support base 408 and its upper end pushing the movable contact block 404. When the movable contact block 404 is pushed upward and close to the fixed contact block 403, the scissor-type telescopic mechanism 402 extends; when the electric actuator 407 retracts, it moves the movable contact block 404 away from the fixed contact block 403, thus shortening the scissor-type telescopic mechanism 402. By electrically driving the telescopic support module 4, the movement of the gable wall 203 is controlled, saving manpower and realizing the automated telescopic extension of the house. To facilitate the installation of the electric actuator 407, a support base 408 is fixedly connected to the lower end of the slide groove 401; an abutment plate is fixedly connected to the lower side of the moving contact block 404, and the abutment plate abuts against the outer end of the piston rod of the electric actuator 407.

[0045] Alternatively, the extended sidewall 204 is located on the side of the mother compartment 1, the gable wall 203 is located outside the extended sidewall 204, the extended top plate 201 is located outside the gable wall 203, and the extended bottom plate 202 is located outside the extended top plate 201. The outer end of the extended bottom plate 202 is connected to the extended top plate 201 via a buckle or hook. This embodiment specifically defines the distribution structure of each block of the extended compartment 2. This distribution structure allows the side panels to extend sequentially, facilitating installation. The later-extended structure provides support and reinforcement to the earlier-extended structure, ensuring the stability of the overall structure. The fixing method of the extended bottom plate 202 can prevent the structure from collapsing when retracted.

[0046] To enhance automation, alternatively, hydraulic telescopic rods can be symmetrically installed on both sides of the extended base plate 202. One end of each hydraulic telescopic rod is hinged to the side wall of the extended base plate 202, and the other end is hinged to the front wall 103 and the rear wall 104. The extended base plate 202 is flipped by the hydraulic telescopic rods, achieving automated extension and retraction of the building. Similarly, hydraulic telescopic rods can also be installed on both sides of the extended top plate 201. This set of hydraulic telescopic rods works in conjunction with the gable wall 203 to drive the extended top plate 201 to flip.

[0047] The slide rail 8 is equipped with a stop plate at the end to prevent the pulley 6 from coming off; the slide rail 8 is embedded in the extended top plate 201 and the extended bottom plate 202, so that the slide rail 8 does not occupy the interior space of the house, the structure is more compact, and the overall house is more beautiful.

[0048] Optionally, the height of the gable wall 203 is lower than the height of the mother chamber 1, so that the outer end of the extended top plate 201 is tilted downward. The tilt angle of the extended top plate 201 is 30° to 45°. The tilted extended top plate 201 facilitates the linkage of its gable wall 203, and the tilted top plate avoids the accumulation of debris and is easy to clean.

[0049] A roof panel 3 is also provided on the upper side of the roof panel 101. The roof panel 3 extends to the outside of the extended roof panel 201 on both sides, thereby covering the connection seam between the extended roof panel 201 and the roof panel 101, and providing rain and water protection.

[0050] The expansion and contraction process of this plan: When unfolding this folding house, first flip the extended base plate 202 downwards and unfold it; then pull the gable wall 203 outwards. The gable wall 203 is stabilized on both sides by the telescopic support module 4. As the gable wall 203 moves, the upper end drives the extended top to flip upwards and unfold. After the gable wall 203 is in place, the upper end is still under the outer end of the extended top plate 201, supporting the extended top plate 201; the telescopic support module 4 is locked by the electric push rod 407; finally, push the extended side wall 204 outwards from inside the mother compartment 1. The extended side wall 204 is positioned and stopped at the predetermined position by the scissor telescopic mechanism 402. Its upper end also supports the extended top plate 201. Finally, strengthen and fix the unfolded side panels to complete the overall installation of the building.

[0051] When folding this folding house, first release the fasteners on each side panel. First, flip the extended side wall 204 back into the mother compartment 1. Second, push the gable wall 203 towards the mother compartment 1. As the gable wall 203 moves closer to the mother compartment 1, the outer wall of the extended top plate 201, lacking support, will flip downwards. The gable wall 203 and the extended top plate 201 will fold together synchronously. Finally, flip the extended bottom plate 202 upwards and attach it to the outside of the extended top plate 201.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
