Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted tents and water transport technology, specifically an inflatable foldable box. Background Technology

[0002] As an outdoor equipment that expands the usable space of a vehicle and provides users with temporary rest and protection, car tents are seeing increasing market demand due to the growing popularity of self-driving tours and camping activities. Currently, mainstream car tents can be divided into three categories based on their structural principles: traditional metal-frame folding tents, inflatable folding tents, and panel-type folding hard-shell tents.

[0003] Traditional metal-frame tents (such as the scheme disclosed in CN109488104A) typically consist of multiple sets of metal poles and a canopy. Their advantages lie in high mechanical strength, structural stability, and good wind resistance. However, this structure has significant drawbacks: First, the installation and disassembly process is cumbersome and lengthy, requiring manual assembly and fixing of numerous poles and connectors, consuming considerable time and effort; second, when folded, they are bulky and heavy, making it difficult to compactly store the metal poles and canopy, occupying vehicle space and resulting in poor portability.

[0004] To improve convenience, inflatable tents were developed (e.g., CN117605346A). These products eliminate the rigid frame, using inflatable columns within the tent fabric to create support through inflation. Their advantages include small size, light weight, and quick deployment. However, because their support relies entirely on gas pressure and the tension of the flexible material, the overall structural rigidity is severely insufficient. When encountering strong winds, snow accumulation, or external impacts, the air columns are prone to bending and deformation, resulting in poor overall tent stability and a risk of swaying, tipping over, or even breakage, making it difficult to provide reliable safety and comfort.

[0005] Panel-style folding hard-shell tents offer a compromise, eliminating the assembly steps of traditional metal-frame tents and resulting in a more compact structure. However, the unfolding and packing processes still require manual intervention, and it's difficult to achieve a good balance between portability, protective strength, and insulation performance, thus failing to fully meet users' comprehensive needs for convenience and reliability.

[0006] Comprehensive analysis reveals that existing technologies consistently struggle to simultaneously address the two core requirements of "high-strength protection" and "thermal and sound insulation" with "portable deployment and storage": metal-structured tents sacrifice portability, while inflatable tents sacrifice structural integrity, safety, and stability. This contradiction has become a key bottleneck restricting the development of vehicle-mounted tent technology. Therefore, the market urgently needs a new solution that can maintain high mechanical strength and impact resistance while achieving rapid, labor-saving, and compact deployment and storage, thereby truly meeting users' comprehensive needs for reliability, safety, and convenience. Summary of the Invention

[0007] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an inflatable foldable box, which solves the problems existing in the background technology.

[0008] (II) Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solution: an inflatable foldable box, including but not limited to a foldable outer shell, an inflatable inner liner, an air pump, a control valve, and inflation / deflation pipelines.

[0009] The foldable shell is a polyhedron with a relatively independent internal space, formed by hinges connecting multiple planar or curved surfaces of specific shapes and sizes with certain mechanical strength and thickness. Its external contour and internal space shape include, but are not limited to, various geometric shapes such as cubes, cuboids, wedges, trapezoids, and cylinders. This foldable shell provides the strongest possible mechanical protection to its internal space, capable of withstanding strong mechanical impacts, resisting attacks from common wild animals, and preventing punctures and scratches from common sharp objects. It can reliably protect the safety of various internal components, facilities, or personnel for a long period. Because the foldable shell only provides safety protection and foldable expansion functions, and does not need to possess the waterproof, sealing, heat insulation, and sound insulation properties achieved by traditional enclosures through increased material thickness, volume, and weight, it significantly reduces the thickness, volume, and weight of raw materials, achieving a greater volume change ratio under the same protection strength conditions.

[0010] Each planar or curved surface that makes up the foldable shell can shrink or enlarge its internal space and external volume according to the positional changes determined by their spatial connection and interaction. When the volume is shrunk to its minimum, it is in a folded storage state for easy carrying; when the volume is enlarged to its maximum, it is in an unfolded state to meet the space requirements of camping, working, etc. Optimally, the volume change ratio between the folded storage state and the unfolded state is maximized while ensuring safety and reliability.

[0011] The inflatable inner liner is housed inside the foldable outer shell and includes components such as inflatable air columns or inflatable walls, single or multiple layers of tent fabric or other enclosing materials, doors and windows, screens, curtains, and drapes. The inflatable air columns or inflatable walls construct the main spatial structure of the inflatable inner liner. The single or multiple layers of tent fabric or other enclosing materials are sealed to the inflatable air columns or inflatable walls to form the various walls, top, and bottom surfaces of the inflatable inner liner. The external shape and dimensions of the inflatable inner liner correspond to the internal spatial shape and dimensions of the foldable outer shell, and the opening positions of the doors, windows, and screens on it correspond to the pre-reserved positions for doors and windows on the foldable outer shell. The outside of the inflatable inner liner is connected and fixed to the inside of the foldable outer shell using methods such as ropes, buckles, and adhesives, ensuring that the outer surface of the inflatable inner liner fits maximally against the inner surface of the foldable outer shell, whether it is filled with gas or deflated.

[0012] For applications with relatively mild ambient temperatures, the inflatable inner liner can utilize a structure combining inflatable columns with single or multiple layers of tent fabric. The inflatable columns are arranged according to the geometric shape of the foldable outer shell's internal framework. Tent fabric, possessing waterproof, windproof, and high / low temperature resistance properties, then encloses the interior of the foldable shell into a sealed space with necessary structural components such as operable doors and windows. At corresponding locations on the inflatable inner liner and foldable outer shell where door and window structures are located, operable transparent soft glass, curtains, or insect screens are installed to improve lighting, visibility, ventilation, and internal air quality, while preventing insect intrusion.

[0013] To improve adaptability to harsh climatic conditions such as extremely high or low temperatures, the inflatable inner liner can be made of a certain thickness of drawn inflatable fabric to create inflatable walls, inflatable top panels, inflatable bottom panels, and other planar or curved surfaces corresponding to the various surfaces inside the foldable outer shell. More preferably, inflatable door and window openings can also be made of drawn inflatable fabric to create freely opening and closing inflatable door and window panels with the same shape and size as the openings, further improving the thermal insulation performance of these areas. The inflatable walls, inflatable top panels, inflatable bottom panels, inflatable door panels, and inflatable window panels are interconnected via inflation tubing. Adjacent inflatable walls, top panels, or bottom panels are sealed together with tent fabric to form a unified, airtight three-dimensional space. Strips of tent fabric act as flexible hinges, connecting the inflatable door panels to the inflatable door frame and the inflatable window panels to the inflatable window frame, creating an openable and closable unit.

[0014] The inflatable inner liner is not merely a standard inflatable tent component offering comfort features such as waterproofing, dustproofing, windproofing, insect protection, insulation, cushioning, impact resistance, and sound insulation; it is also a power output component that applies folding and unfolding force to the foldable outer shell. During inflation, the outer surface of the inflatable inner liner applies a uniform unfolding force perpendicular to the inner surface of the foldable outer shell. During deflation, the outer surface of the inflatable inner liner also applies a uniform folding force perpendicular to the inner surface of the foldable outer shell. Because gas can expand or contract in either direction, the inflatable inner liner can continuously and uniformly apply folding or unfolding force perpendicular to the inner surface of the foldable outer shell, all without requiring additional space or weight. Furthermore, the inflatable inner liner can disperse, buffer, and automatically reset the impact force and deformation experienced by the foldable outer shell, further enhancing its mechanical protection and durability.

[0015] The air pump, control valves, and inflation / deflation piping together form the inflation / deflation control system for the inflatable inner liner. High-pressure gas discharged from the air pump inflates the inner liner via the control valves and piping, enabling the inflatable foldable case to expand. Negative pressure at the air pump inlet deflates the inner liner via the control valves and piping, allowing the case to fold away. In the event of a minor leak in the inner liner and the lack of repair tools and materials, the air pump can perform emergency inflation or deflation operations via the control valves and piping to ensure the case remains in its intended condition.

[0016] (III) Beneficial Effects This invention provides an inflatable foldable box, which has the following beneficial effects: 1. This invention creatively employs a composite structure of a "rigid foldable outer shell" and a "flexible inflatable inner liner," successfully resolving the core contradiction in traditional equipment where protection, insulation, and portability are difficult to balance. The foldable outer shell is composed of hinged rigid panels, forming a robust protective structure when unfolded, effectively resisting external impacts, punctures, and wildlife intrusion, providing safety comparable to traditional hard-shell boxes or metal-framed tents. Simultaneously, the inflatable inner liner not only provides comfort functions such as sealing, insulation, and soundproofing, but its uniform and continuous driving force generated during inflation and deflation replaces complex electric push rods, hydraulic rods, or manual support mechanisms, becoming the primary power source for driving the folding and unfolding of the outer shell. This design fully automates the storage and unfolding of the entire enclosure, completing the process with a single button, completely eliminating the drawbacks of cumbersome and time-consuming assembly and disassembly of traditional metal-framed tents. It achieves a more convenient function than inflatable tents; while inflatable tents can automatically expand and take shape through inflation, deflation only allows for the tent to collapse, making automatic folding difficult.

[0017] 2. The inflatable inner liner of this invention, as a variable-thickness gaseous medium insulation layer, offers superior thermal insulation performance compared to traditional solid insulation materials. It is unaffected by ambient humidity, effectively solving the "cold bridge" condensation problem inherent in traditional hard-shell enclosures. When inflated, the inner liner exhibits excellent elasticity and cushioning, dispersing external impact forces and automatically restoring the enclosure's deformation, significantly improving the overall structure's impact resistance and durability. After deflation, the inner liner and outer shell can be folded synchronously to an ultra-thin state, achieving a volume change ratio far exceeding that of traditional hard-shell folding enclosures (up to 10 times or more). Furthermore, multiple enclosures can be flexibly cascaded horizontally or vertically via standardized interfaces. Each unit can be used independently or connected as a whole, managed uniformly or independently through a central control system, greatly expanding application scenarios and meeting space requirements of varying sizes, from individual camping to group campsites.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0021] This embodiment provides a standard-height inflatable foldable box suitable for vehicle rooftop platforms, its unfolded state as follows: Figure 1 and Figure 4 As shown, the folded storage state is as follows Figure 5 As shown in the image. This enclosure primarily serves to meet the space needs of users for sitting, lying down, and resting while camping.

[0022] The foldable shell, when unfolded, forms a closed cuboid, hinged together by multiple rigid panels of specific shapes. See details... Figure 1 The outer shell includes components 1, 2, 3, 4, 7, 8, 11, 12, 13, 14, 15, and 17. The connection relationships between the panels are as follows: the left edges of components 4 and 14 are connected to components 1 and 11 respectively via hinges, and their right edges are connected to components 8 and 17 respectively via hinges. Component 1 is hinged to component 2, and component 2 is hinged to component 3. Similarly, the other side is hinged to component 3 via components 8 and 7. The bottom structure is symmetrical. A door structure, including components 9, 18, 10, and 19, is provided on the right facade. A window structure, including components 6 and 5, is provided on the rear facade. The arrangement of all hinges allows the outer shell to fold along a predetermined trajectory, ultimately folding into the shape shown below. Figure 5 The flat shape shown.

[0023] An inflatable inner liner is disposed inside the outer shell, and one preferred structure is as follows: Figure 4As shown. The inner liner is made of pneumatic fabric and includes components 24, 25, 22, and 27. These inflatable walls are sealed to the top and bottom plates by high-frequency welding or adhesive bonding to form a sealed air chamber. Components 28 and 21 are provided at positions corresponding to the doors and windows of the outer shell. They are connected to the surrounding inflatable walls by flexible hinges made of strip fabric, enabling opening and closing. The outer surface of the inner liner is connected to fixed points on the inner wall of the outer shell through several components 20, ensuring that the inner liner can effectively expand and conform to the inner surface of the outer shell during inflation, and can fold orderly with the outer shell during deflation, avoiding entanglement.

[0024] Inflation and deflation control system (its principle is described in...) Figure 2 The control system is connected to the air chambers of the inflatable inner liner via component 60. The control system includes component 67, multiple control valves (components 64, 65, 66, 68), component 61, component 62, and component 63. During deployment, the inflation circuit valves (components 65, 66) are opened, and component 67 is activated, allowing gas to fill the inner liner. The inner liner expands, applying a uniform thrust to each panel of the outer shell, driving each panel to rotate around the hinge axis and ultimately lock in the deployed position (e.g., ...). Figure 1 (As shown). During storage, open the exhaust circuit valves (parts 64, 68), and part 67 will work to draw air or utilize natural exhaust. The inner liner will contract, and the combined effect of internal negative pressure and the outer shell's own weight will pull each panel inward in sequence until it reaches its maximum position. Figure 5 The compact storage configuration is shown. Throughout the process, component 63 monitors the pressure, and component 61 prevents overpressure. Example 2:

[0025] This embodiment improves upon the box described in Embodiment 1, providing a tall-top inflatable foldable box that allows adults to stand and walk naturally inside. Its structure is as follows: Figure 3 As shown.

[0026] In this embodiment, the foldable shell increases the interior space by increasing the height of the facade panels. (See also...) Figure 3 Its main components include components 29, 30, 31, 32, 35, 36, 39, 40, 41, 42, 45, and 46. Its hinged connection method is similar to that of Embodiment 1, but due to the change in size, its folding is slightly different, ultimately allowing it to be folded into a thin shape. With the increased height, larger through-holes will form on the front and rear facades. Therefore, components 31 and 41 are integrated with retractable or flip-out components 33 and 43, as well as components 34 and 44, which are hidden during storage and pulled out or opened after unfolding to compensate for the weak points in protection caused by the structural changes, achieving fully enclosed protection.

[0027] The inflatable inner liner structure that matches the high-top outer shell is also correspondingly increased in height, such as... Figure 3The right side section includes taller components 54, 55, 52, and 57. Components 58, 51, and 59 are also provided and secured by component 50. Its operating principle is the same as in Embodiment 1, using inflation and deflation to drive the unfolding and retraction of the tall outer shell. Example 3:

[0028] This embodiment focuses on describing the implementation of intelligent control of inflatable foldable boxes and the combined application of multiple boxes. The principle of the control system is described in [link to documentation]. Figure 2 .

[0029] In a preferred embodiment, the inflation / deflation control system can be upgraded to an intelligent mode. A controller (not shown in the figure, which may be integrated into component 67 or set independently) receives real-time pressure signals from a pressure sensor (integrated in the pipeline, not shown in the figure). The user can set the target working pressure via preset or APP. The controller, by driving component 67 and controlling the opening and closing of various solenoid valves (components 64, 65, 66, and 68 may be solenoid valves), achieves fully automated control of the entire process, including automatic inflation to the target pressure, automatic pressure maintenance (automatically activating the air pump to replenish pressure when a slight leak is detected), and automatic deflation, greatly improving ease of use and environmental adaptability.

[0030] As described in claim 7, the present invention supports multi-chassis cascading expansion. Multiple such... Figure 1 or Figure 3 The individual housings shown can be physically connected horizontally (left-right, front-back) or vertically (stacked) via dedicated hinges (for rotational connection) or sliding rail mechanisms (for sliding and pulling connection). More importantly, the inflatable inner liner of adjacent housings is connected in parallel via quick-connect air hoses and ultimately integrated into the same central inflation / deflation control system (such as...). Figure 2 The system shown requires a corresponding increase in pump power and gas storage capacity. The controller can be configured with multi-channel independent control functionality, meaning it can control the main valve on the main pipeline and also the independent control valves on the branch pipelines leading to each individual unit (which can be configured to...). Figure 2 The system can be expanded to allow for individual inflation, deflation, or pressure control of specific individual units. This allows users to have both a large, interconnected space and maintain the independence and privacy of each space, meeting the needs of complex scenarios such as campsites and mobile offices. Example 4:

[0031] Inflatable foldable enclosures can also be used in waterborne vehicles. In this embodiment, both the foldable outer shell and the inflatable inner liner are made of special waterproof and corrosion-resistant materials, enabling them to adapt to the special requirements of the aquatic environment. When inflated, the inflatable inner liner provides structural support and excellent buoyancy, enhancing the stability and safety of the waterborne vehicle.

[0032] Furthermore, the pressure difference between the inside and outside of the inflatable inner liner is the primary power source driving the unfolding or retraction of the foldable outer shell. This design allows the enclosure to cushion the impacts and fluctuations of the aquatic environment through the flexible deformation of the inner liner, effectively protecting the items and personnel inside. Simultaneously, the elasticity and resilience of the inflatable inner liner enable it to automatically recover its shape after being subjected to external impacts, further enhancing the reliability and durability of the enclosure. Example 5:

[0033] The inflatable, foldable box can be integrated into any part of a vehicle, including but not limited to the top, sides, or rear, where space expansion is possible or necessary. In this embodiment, the box is fixed to the vehicle body, including but not limited to the top, sides, or rear, and is tightly connected to the vehicle through a specially designed fixing device. When the box is needed, the inflation / deflation control system is activated, and the box quickly unfolds, providing the vehicle owner with additional storage space or a temporary resting place.

[0034] To withstand the bumps and vibrations during vehicle operation, both the foldable outer shell and the inflatable inner liner are made of high-strength and high-toughness materials. Meanwhile, the self-adjusting folding and reinforcing structure of the inflatable inner liner provides additional stability during vehicle movement, preventing the box from loosening or being damaged by external impacts. When the vehicle is parked, the box can also serve as a sunshade and rain shelter, providing convenience for the owner's outdoor activities.

At the same time, unless otherwise expressly specified and limited, the terms "set," "install," "connect," and "fixed installation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a pneumatic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction relationship between two elements. Unless otherwise expressly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
