Description

Technical Field

[0001] This utility model belongs to the field of folding house technology, specifically a folding mobile house. Background Technology

[0002] Mobile homes are dwellings that can be easily assembled and moved, such as those that can be towed behind a car. They resemble trailers on the outside but function as living spaces on the inside. These types of homes are common in Western countries. They also have applications in China, including environmentally friendly public toilets, sanitation facilities, light steel frame houses, and wooden houses used in outdoor construction.

[0003] Existing folding mobile homes generally suffer from complex folding and unfolding operations and poor interoperability of components in their structural design. For example, the connection between the side walls and the base often uses a single hinge or sliding rail structure, resulting in limited volume reduction after folding and a tendency for misalignment during unfolding. At the same time, their thermal insulation and sealing performance are insufficient. Traditional windows often use ordinary double-glazed glass, and the wall filling material is often a single insulation layer, making it difficult to meet the requirements of efficient thermal insulation and sound insulation. In addition, switching between moving and fixed functions often requires additional tools, and the ground anchors are set separately from the moving parts, making operation cumbersome and unstable. Furthermore, the connection and sealing between the window frame and the surrounding structure are poor, making it easy for problems such as air leakage and water seepage to occur, which makes it difficult to meet the comprehensive requirements of portability, comfort and reliability. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a foldable mobile house to solve the problems of complex folding operation, insufficient heat insulation and sound insulation performance, cumbersome switching between moving and fixing, and poor sealing of existing foldable mobile houses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a folding mobile house, characterized in that it includes a base, windows, and side walls. The base is generally set as a cuboid, and a support plate is provided on the base. The support plate is divided into four groups, and each group of support plates is symmetrically fixed to each other according to the central axis of the long and short sides of the base. Each group of support plates has two plates, and each support plate is connected to each other by a fixing block. A door panel is installed between the two groups of support plates on the short side of the base. A telescopic connecting rod is installed on the fixing block. The two ends of the side walls are provided with hollows, and the other end of the telescopic connecting rod is installed in the hollow of the side wall. The side wall moves due to the extension and retraction of the telescopic connecting rod. A telescopic base is installed on the base, and the telescopic base is connected to the side walls. Window frames are slidably and symmetrically arranged on the telescopic base with the door panel as the center. The window is installed inside the window frame. The window frame is set as a sliding window type and is magnetically connected to the support plate, side walls, and telescopic base. A ceiling is installed on the top surface of the support plate and side walls. The ceiling is set to be telescopic and moves with the side walls.

[0006] Optionally, the window is configured as a vacuum low-E three-wave two-cavity structure, which is formed by sealing and splicing three substrate glass pieces through a low thermal conductivity spacer frame to form two independent vacuum cavities. Spacer strips are installed in the two internal cavities, and desiccant is placed inside the spacer strips. The side wall is filled with a polyurethane foam layer, and a vacuum insulation board is connected inside the polyurethane foam layer.

[0007] Optionally, a silicone pad is provided at the telescopic extension point of the telescopic base.

[0008] Optionally, an anchoring mechanism is installed at the four corners of the side wall. The anchoring mechanism includes a support column, a compression block, a flange, a pulley, and a ground nail. The support column is embedded inside the side wall. The compression block is slidably installed on the support column. The flange is evenly installed at the bottom of the support column in a circular array with the support column as the center. The ground nail is fixed to the bottom surface of the flange. The pulley is installed at the bottom of the support column. When the flange is unfolded, the height of the ground nail is lower than that of the pulley.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention improves structural linkage and ease of operation. It connects four symmetrically arranged support plates and fixed blocks, and works with telescopic linkages to drive the side walls to move, forming a coordinated linkage mechanism. This synchronizes and automates the folding and unfolding process. Compared with traditional single hinge or sliding rail structures, the number of operation steps is greatly reduced, and the problem of component misalignment during unfolding is effectively avoided. The retractable ceiling adapts to the movement of the side walls, ensuring a significant reduction in volume after folding, thus improving transportation and storage efficiency. This invention optimizes thermal insulation and energy-saving performance. The window adopts a vacuum low-E three-wave two-cavity structure. Through the combination of double vacuum cavities and low-emissivity coating, it has excellent thermal insulation performance and significantly saves energy compared to ordinary insulated glass. It also has good sound insulation and ultraviolet blocking capabilities. The interior of the side wall adopts a composite filling design of polyurethane foam layer and vacuum insulation board to form a gradient insulation layer, which significantly improves the thermal insulation efficiency compared to single insulation materials and can adapt to various extreme temperature environments. This utility model can achieve efficient integration of mobile and fixed functions: the anchoring mechanism at the four corners of the side wall is designed with the linkage of the support column, the compression block and the flange plate. Pressing it can drive the flange plate to unfold, so that the ground nail can automatically penetrate into the ground to achieve stable fixation; when released, the flange plate returns to its original position and the pulley contacts the ground. The "fixed-mobile" switch can be completed without additional tools, adapting to various terrains such as grass, gravel and cement, and improving the flexibility of emergency deployment and relocation.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figures 1 to 6 As shown, this utility model provides a foldable mobile house, characterized by comprising a base 1, windows 2, and side walls 3. The base 1 is generally rectangular, and support plates 4 are provided on the base 1. The support plates 4 are divided into four groups, and each group of support plates 4 is symmetrically fixed to each other according to the central axis of the long and short sides of the base 1. Each group of support plates 4 has two plates, and each support plate 4 is connected to each other by fixing blocks 5. A door panel 8 is installed between the two groups of support plates 4 on the short side of the base 1. Telescopic connecting rods 6 are installed on the fixing blocks 5. The side walls 3 have hollowed-out ends, and the telescopic connecting rods 6... The other end of the connecting rod 6 is installed in the hollow of the side wall 3. The side wall 3 moves due to the extension and retraction of the telescopic connecting rod 6. A telescopic base 7 is installed on the base 1. The telescopic base 7 is connected to the side wall 3. A window frame 9 is slidably and symmetrically arranged on the telescopic base 7 with the door panel 8 as the center. The window 2 is installed in the window frame 9. The window frame 9 is set as a sliding window and is magnetically connected to the support plate 4, the side wall 3 and the telescopic base 7. A ceiling 10 is installed on the top surface of the support plate 4 and the side wall 3. The ceiling 10 is set as telescopic and moves with the side wall 3.

[0013] Specifically, this utility model can improve structural linkage and ease of operation. By connecting four sets of symmetrically arranged support plates 4 and fixed blocks 5, and cooperating with telescopic linkages 6 to drive the side walls to move, a collaborative linkage mechanism is formed, which synchronizes and automates the folding and unfolding process. Compared with the traditional single hinge or sliding rail structure, the operation steps are greatly reduced, and the problem of component misalignment during unfolding is effectively avoided. The ceiling 10 adopts a three-unit modular design of "central fixed plate + two movable telescopic plates". The central plate serves as the reference bearing unit, providing structural support and positioning reference. It is usually rigidly connected to the main keel of the ceiling or the fixed structure. The two movable plates are movable telescopic units. Through mechanical connection and cooperation with the central plate, the space coverage range can be dynamically adjusted and adaptively extended and retracted as the side walls 3 move, ensuring that the volume is significantly reduced after folding and improving transportation and storage efficiency.

[0014] The window 2 is configured as a vacuum low-E three-wave two-cavity structure, which is formed by three substrate glass pieces sealed and spliced ​​together by a low thermal conductivity spacer frame to form two independent vacuum cavities. Spacer strips 11 are installed in the two internal cavities, and desiccant 12 is placed inside the spacer strips 11. The side wall 3 is filled with a polyurethane foam layer 13, and a vacuum insulation board 14 is connected inside the polyurethane foam layer 13.

[0015] Specifically, this utility model can optimize thermal insulation and energy-saving performance. The window 2 adopts a vacuum low-E three-wave two-cavity structure. Through the combination of double vacuum cavities and low-emissivity coating, it has excellent thermal insulation performance and significantly saves energy compared with ordinary insulated glass. At the same time, it has good sound insulation and ultraviolet blocking capabilities. The side wall 3 adopts a composite filling design of polyurethane foam layer 13 and vacuum insulation board 14 to form a gradient insulation layer. The insulation efficiency is significantly improved compared with single insulation material and can adapt to a variety of extreme temperature environments.

[0016] Specifically, the polyurethane foam layer 13 filling the wall 3 has excellent thermal performance and a high closed-cell rate, which can form a continuous and sealed thermal insulation cavity, effectively blocking the heat transfer path of the wall, reducing the heat transfer coefficient of the building envelope, and meeting the stringent requirements for wall insulation performance in building energy-saving design standards. Secondly, the polyurethane foam layer 13 has high mechanical property adaptability. The foam can form an interface bond with wall substrates such as concrete and masonry. It can not only bear its own weight and slight external forces, but also buffer the temperature stress and drying shrinkage deformation of the wall substrate through elastic deformation. Finally, the polyurethane foam layer 13 also has outstanding water vapor barrier capability. The closed-cell structure can block the penetration of liquid water and the migration of gaseous water, effectively reducing the risk of condensation inside the wall and avoiding mold growth and structural damage to the substrate.

[0017] The telescopic base 7 is equipped with a silicone pad 15 at its telescopic extension point.

[0018] Specifically, the window frame 9 adopts a sliding design and forms a magnetic connection with the support plate 4, side wall 3, and telescopic base 7. Together with the silicone pad 15 at the telescopic point of the telescopic base 7, multiple seals are achieved to effectively prevent wind and rain penetration and heat loss. The linkage structure between the side wall 3 and the base 1 reduces the gaps in traditional splicing, further reducing the risk of air leakage and water seepage, and improving the stability and comfort of the indoor environment.

[0019] Anchoring mechanisms 16 are installed at the four corners of the side wall 3. The anchoring mechanism 16 includes a support column 17, a pressing block 18, a flange 19, a pulley 20, and a ground nail 21. The support column 17 is embedded inside the side wall 3. The pressing block 18 is slidably installed on the support column 17. The flange 19 is evenly installed at the bottom of the support column 17 in a circular array with the support column 17 as the center. The ground nail 21 is fixed to the bottom surface of the flange 19. The pulley 20 is installed at the bottom of the support column 17. After the flange 19 is unfolded, the height of the ground nail 21 is lower than that of the pulley 20.

[0020] Specifically, this utility model can achieve efficient integration of mobile and fixed functions. The anchoring mechanism 16 at the four corners of the side wall 3, through the linkage design of the support column 17, the compression block 18 and the flange 19, can drive the flange 19 to unfold by pressing the piston mechanism, so that the ground nail 21 automatically penetrates the ground to achieve stable fixation; when released, the flange 19 returns to its original position and the pulley 20 contacts the ground. The "fixed-mobile" switch can be completed without additional tools, adapting to various terrains such as grass, gravel, and cement, and improving the flexibility of emergency deployment and relocation.

[0021] The working principle and usage process of this utility model: This foldable mobile house achieves folding and function switching through the linkage of multiple components. The usage process is as follows: When stored or transported, it is in a folded state. The side wall 3 retracts towards the center of the base 1 along the telescopic linkage 6, and the telescopic ceiling 10 retracts simultaneously. The window frame 9 slides along the telescopic base 7 towards the door panel 8. When unfolded, the telescopic linkage 6 extends, driving the side wall 3 to move outward along the base 1. The support plate 4 and the fixing block 5 form a stable support. The ceiling 10 unfolds along with the side wall 3 to cover the top, and the window frame 9 slides to the corresponding position, magnetically connecting and sealing with the surrounding structure. When fixed, pressing the four corner anchoring mechanisms 16 of the side wall 3 causes the squeezing block 18 to drive the flange 19 to unfold, and the ground nail 21 is driven into the ground for anchoring. When moving, releasing the anchoring mechanism 16 resets the flange 19, and the pulley 20 can be pushed when it contacts the ground. When stored, the telescopic linkage 6 retracts in the opposite direction, and all components retract synchronously to return to the folded state. The silicone pad 15 and the magnetic connection ensure a tight seal throughout the process.
