Description

Technical Field

[0001] This application relates to the field of rooftop tent technology, and more particularly to a fully inflatable rooftop tent that reduces working pressure and a method for setting it up. Background Technology

[0002] Currently, inflatable rooftop tents on the market mainly fall into two structural types: a rigid platform + air columns and an air cushion platform + air columns. The former requires unfolding the rigid platform and then inflating the air columns to support the entire main tent, while the latter uses an inflatable air cushion platform, effectively reducing the overall weight of the rooftop tent and simplifying installation and disassembly. Fully inflatable rooftop tents are increasingly popular due to their quick deployment and storage advantages. These tents typically consist of a bottom supporting air cushion and an upper frame of air columns, with inflation establishing a rigid structure. Existing fully inflatable rooftop tents have relatively thin supporting air cushions (usually between 10-15cm). To support the user's weight and maintain sufficient stability and support, preventing the user from hitting the bottom while sleeping, these thin air cushions need to be inflated to a high working pressure (e.g., 12 psi or higher). This requires a high-powered pump, results in a long inflation time, and adds weight to the equipment. The high pressure of 12 psi or higher also carries a high risk of bursting and leakage. It feels firm to sleep on, has average heat retention, and a bottoming sensation. Inflatable mattresses require high-strength, pressure-resistant materials and have stringent manufacturing requirements.

[0003] Currently, the air cushion and air column are designed as separate units. For safety reasons, the air cushion needs to maintain a certain level of rigidity and requires inflation to 12 psi or higher, while the air column only needs to be inflated to 6-8 psi. Inflating to more than 8 psi will affect the durability and safety of the air column structure and may even pose a risk of bursting. The separate structure of the air cushion and air column cannot achieve integrated inflation, and cannot balance the support of the air cushion and the safety of the air column.

[0004] Existing patent publication number CN217631652U discloses an inflatable car roof tent, including a support platform, an inflatable frame connected to the support platform, and a tent fabric erected on the inflatable frame. The support platform is an inflatable air cushion, and a mounting connecting pipe is connected to the bottom of the support platform. The mounting connecting pipe is an inflatable structure, and the support platform is connected and fixed to the car through the mounting connecting pipe. The mounting connecting pipe has two inflatable inner bladders, which are arranged side by side and laid flat. This invention provides an inflatable car roof tent where not only the frame and support platform are inflatable structures, but the mounting connecting pipe is also an inflatable structure. It is clear that in the aforementioned existing patent, the support platform and the mounting connecting pipe have separate inflatable inner bladders, which are inflated separately. Users need to inflate the air cushion and the air column separately, which is more complicated and inconvenient for users.

[0005] Currently, in order to achieve good support performance, air cushions need to be supplied with high operating pressure. However, the high operating pressure of existing air cushions brings a series of problems: High energy consumption for inflation: It requires the use of a high-power, heavy-duty electric air pump or takes a longer time to inflate, which is not conducive to outdoor emergency or energy-saving use.

[0006] Safety and comfort risks: Excessive pressure inside the air chamber, long-term use, or temperature changes may lead to the potential for bursting of the air chamber interface or seals, or accelerated air leakage, affecting service life and user safety.

[0007] Stringent material requirements: To withstand high pressure, the air mattress material needs higher tensile strength and more sophisticated seam processing, increasing manufacturing costs. Poor user experience: Excessively high air pressure may make the sleeping mat too firm, affecting sleep comfort.

[0008] Therefore, the urgent technical problem to be solved is how to provide a fully inflatable rooftop tent and its construction method that reduces working pressure. This method involves inflating the supporting air cushion and the frame air column in one go, which is easy to operate and can effectively reduce the working pressure of the supporting air cushion without sacrificing its support performance and stability, thus preventing the frame air column from bursting. Summary of the Invention

[0009] The purpose of this application is to provide a fully inflatable rooftop tent and its construction method that reduces working pressure. The supporting air cushion and the frame air column are inflated in one go, which is simple to operate and can effectively reduce the working pressure of the supporting air cushion without sacrificing the supporting performance and stability of the supporting air cushion, thus avoiding the bursting of the frame air column.

[0010] To achieve the above objectives, this application provides a fully inflatable rooftop tent that reduces working pressure. The bottom of the fully inflatable rooftop tent is fixedly connected to the roof of the vehicle. The fully inflatable rooftop tent includes: a tent fabric and an inflatable frame. The tent fabric covers the outside of the inflatable frame to form a tent space. The inflatable frame includes: a supporting air cushion for providing a sleeping platform and a frame air column for supporting the tent space. The frame air column is disposed above the supporting air cushion. The sealed air chambers of the supporting air cushion and the sealed air chambers of the frame air column are connected and share a single inflation valve. Inflation is performed through the inflation valve to the sealed air chambers of the supporting air cushion and the frame air column. The top of the supporting air cushion forms a sleeping platform, and the frame air column forms a rigid support structure supporting the tent fabric.

[0011] The fully inflatable rooftop tent described above, designed to reduce working pressure, has a supporting air cushion with an inflated height ranging from 20 to 40 cm.

[0012] The fully inflatable rooftop tent for reducing working pressure, as described above, has at least one connection between the supporting air cushion and the frame air column, the connection connecting the sealed air chamber of the supporting air cushion and the sealed air chamber of the frame air column.

[0013] As described above, the fully inflatable rooftop tent that reduces working pressure includes an inflation valve located on the supporting air cushion or the frame air column, through which air is simultaneously injected into the supporting air cushion and the frame air column.

[0014] As described above, the fully inflatable rooftop tent that reduces working pressure includes a support air cushion and a frame air column that are integrally molded or sealed together to form a continuous inflatable air chamber.

[0015] As described above, the fully inflatable rooftop tent for reducing working pressure includes a ventilation pipe at the connection port for the supporting air cushion and the frame air column. One end of the ventilation pipe is connected to the supporting air cushion, and the other end is connected to the frame air column.

[0016] As described above, the fully inflatable rooftop tent for reducing working pressure includes a frame air column comprising: multiple uprights, crossbeams, diagonal beams, and a top ridge; the multiple uprights are respectively connected to the four corners of the supporting air cushion; the two ends of the crossbeams are respectively connected to two adjacent uprights; the diagonal beams are inclined, with the bottom of the diagonal beams connected to the crossbeams and the top of the diagonal beams connected to the top ridge, forming a ridge-like structure.

[0017] The fully inflatable rooftop tent described above, designed to reduce working pressure, includes interconnected air chambers in the multiple uprights, crossbeams, diagonal beams, and top ridge.

[0018] As described above, the fully inflatable rooftop tent that reduces working pressure includes a tent fabric covering the outside of the inflatable frame to form a closed tent space; the tent fabric is provided with an entrance / exit for entering and exiting the tent space, and the edge of the entrance / exit is connected to the tent fabric by a zipper.

[0019] This application provides a method for setting up a fully inflatable rooftop tent that reduces working pressure. The method includes: fixing the rooftop tent to the top of a vehicle; simultaneously inflating the supporting air cushion and the frame air columns using a single inflation valve; controlling the inflation pressure of the inflation valve within a predetermined range, causing the supporting air cushion to expand and form a sleeping support platform, while the frame air columns expand to form a support frame for the tent space; wherein the predetermined range for controlling the inflation pressure of the inflation valve is 4-8 psi; and wherein the thickness of the inflated supporting air cushion is 20-40 cm.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1 and 2As shown, this application provides a fully inflatable rooftop tent that reduces working pressure. The bottom of the fully inflatable rooftop tent is fixedly connected to the roof of the vehicle. The fully inflatable rooftop tent includes: a tent fabric 1 and an inflatable frame. The tent fabric 1 covers the outside of the inflatable frame to form a tent space. The inflatable frame includes: a supporting air cushion 2 for providing a sleeping platform and a frame air column 3 for supporting the tent space. The frame air column 3 is located above the supporting air cushion 2. The sealed air chambers of the supporting air cushion 2 and the sealed air chambers of the frame air column 3 are connected and share a single inflation valve 4. Users can complete the product setup by inflating the inflatable frame once through the single inflation valve 4, making the operation simpler. By inflating the sealed air chambers of the supporting air cushion 2 and the frame air column 3 through the inflation valve 4, a sleeping platform is formed on the top of the supporting air cushion 2, and the frame air column 3 forms a rigid support structure supporting the tent fabric 1. This application achieves pressure self-adaptive balance between the supporting air cushion 2 and the skeleton air column 3 in a connected state. At a relatively low working pressure of 4-8 psi, it ensures the supporting performance of the supporting air cushion 2 while preventing the skeleton air column 3 from bursting. Working pressure refers to the gas pressure (gauge pressure) within the sealed air chamber when the supporting air cushion 2 is inflated to its designed height (height refers to the height of the supporting air cushion 2 from its bottom to its top when placed horizontally) under standard atmospheric pressure and no-load conditions. The working height under rated load refers to the actual height of the supporting air cushion 2 after compression when the rated load is applied.

[0028] As a specific embodiment of the present invention, the height of the inflated support air cushion 2 ranges from 20-40cm. Compared to existing air cushions, the height of the inflated support air cushion 2 is increased, resulting in a larger compressible deformation space (or height) when the user lies down. Under a constant load, the increased height of the inflated support air cushion 2 provides a larger compressible space, and the ratio of the air chamber volume V to the bearing area A (V / A, i.e., equivalent height) is significantly greater than in the prior art. According to the principle of gas compression work, when an external load F is applied to the air cushion, the air cushion stores energy through volume compression ΔV to balance the load. In the prior art, a 15cm high air cushion, when compressed by 20% (3cm), requires a relatively high initial pressure (12psi) to generate sufficient supporting reaction force. The present invention, for example, uses a 30cm high air cushion. A 20% compression, or 6cm compression, allows the gas to generate the same support reaction force at a lower initial pressure (6psi) through a greater rate of volume change. In other words, the present invention can provide the same support reaction force at a lower internal pressure. The thickened support air cushion 2 of this application, inflated to approximately 6psi or lower, can provide essentially the same support reaction force as a 15cm high air cushion in the prior art inflated to 12psi. Therefore, to provide essentially the same support reaction force, the thickened support air cushion 2 of this application can be inflated to a lower working pressure.

[0029] Understandably, existing portable low-pressure air pumps are used to inflate the support air cushion 2 and the frame air column 3 via a single inflation valve. The gas supplied by the portable low-pressure air pump flows freely through the connecting channel between the support air cushion 2 and the frame air column 3, automatically balancing the internal pressure of both to the same working pressure. This application increases the height of the inflated support air cushion 2 to 20-40 cm, providing normal support for the rated load at a working pressure of 4-8 psi, reducing the working pressure required for both the support air cushion 2 and the frame air column 3, thereby preventing the frame air column 3 from bursting under high working pressure.

[0030] It should be explained that the rated load refers to the amount of compression deformation of the support air pad when a uniformly distributed load of 150 kg is applied to the central area of ​​the top of the support air pad (area of ​​40cm×40cm) in accordance with the provisions of GB / T 27735-2011 "Camping Tents" standard for platform load testing.

[0031] It should be explained that in existing technologies, the wall thickness of the skeleton air column is typically 0.3-0.5 mm, the material is TPU, and its burst pressure is approximately 15-20 psi. Considering a safety factor (usually 2.0-2.5), the safe operating pressure should not exceed 6-8 psi. When the supporting air cushion 2 requires a working pressure of 12 psi, the skeleton air column 3, connected to the supporting air cushion 2, will also bear a pressure of 12 psi, exceeding the safe operating pressure and posing a risk of bursting. This application reduces the working pressure of the supporting air cushion 2 and the skeleton air column 3 to 4-8 psi by increasing the height of the supporting air cushion 2 to 20-40 cm, allowing the skeleton air column 3 to operate within the safe operating pressure range.

[0032] This application uses a single inflation valve to simultaneously inflate the supporting air cushion 2 and the frame air column 3, eliminating the need for the cumbersome operation of inflating the supporting air cushion 2 and the frame air column 3 separately, thus simplifying the inflation operation.

[0033] In a preferred embodiment of the present invention, the wall thickness of the skeleton air column 3 ranges from 0.3 to 0.8 mm, and the wall thickness of the supporting air cushion 2 ranges from 0.6 to 1.2 mm. Under no-load conditions, the height formed by the inflated supporting air cushion 2 is preferably 25 cm, with an error of ±2 cm; the working height of the supporting air cushion 2 under rated load is 20-21 cm.

[0034] As a preferred embodiment of the present invention, the design height of the support air cushion 2 is 25cm, that is, when inflated to a working pressure of 6psi under standard atmospheric pressure and no-load conditions, the height from the top to the bottom of the support air cushion is 25cm; under a rated load of 150kg, the working height of the support air cushion is 20cm.

[0035] In a specific embodiment of the present invention, the supporting air cushion 2 and the frame air column 3 have at least one communication port, which connects the sealed air chamber of the supporting air cushion 2 and the sealed air chamber of the frame air column 3, and the sealed air chambers of the supporting air cushion 2 and the frame air column 3 are in a state of mutual communication. An inflation valve 4 is provided on the supporting air cushion 2 or the frame air column 3, and inflation is simultaneously introduced into the supporting air cushion 2 and the frame air column 3 through the inflation valve 4.

[0036] In a specific embodiment of the present invention, the number of connecting ports is preferably 2-4, evenly distributed at the connection between the supporting air cushion and the skeleton air column. The diameter of each connecting port is preferably 2-5 cm to ensure that the gas can flow quickly to achieve pressure balance. When a vent pipe is used for connection, the inner diameter of the vent pipe is preferably 1-3 cm, the length is not more than 10 cm, and the material is the same as that of the supporting air cushion 2.

[0037] As a specific embodiment of the present invention, the supporting air cushion 2 and the skeleton air column 3 are integrally formed or sealed together to form a continuous inflatable air chamber.

[0038] In a specific embodiment of the present invention, a single inflation valve is preferably located on the side wall of the supporting air cushion 2, 5-10 cm from the bottom of the supporting air cushion 2. The inflation valve is an existing component, using a spiral nozzle or a Boston nozzle, with an inner diameter of not less than 1.5 cm to ensure inflation efficiency. The connection between the inflation valve and the supporting air cushion 2 is sealed by high-frequency heat sealing or adhesive bonding to ensure airtightness of the sealed connection. The connection method between the inflation valve and the supporting air cushion 2 is not limited; the inflation valve and the supporting air cushion 2 can be sealed and connected as needed.

[0039] As a specific embodiment of the present invention, the supporting air cushion 2 and the skeleton air column 3 are provided with a vent pipe at the connection port. One end of the vent pipe is connected to the supporting air cushion 2, and the other end is connected to the skeleton air column 3. The connection between the vent pipe and the supporting air cushion 2 and the skeleton air column 3 is a sealed connection.

[0040] like Figure 2 As shown, the air column 3 includes: multiple uprights 31, crossbeams 32, diagonal beams 33, and a top ridge 34; the multiple uprights 31 are respectively connected to the four corners of the supporting air cushion 2; the two ends of the crossbeams 32 are respectively connected to two adjacent uprights 31; the diagonal beams 33 are inclined, with the bottom of the diagonal beams 33 connected to the crossbeams 32 and the top connected to the top ridge 34, forming a ridge-like structure. The ridge-like structure of the present invention improves the stability of the air column 3 structure through the triangular support of the diagonal beams 33 and the longitudinal reinforcement of the top ridge 34.

[0041] In a specific embodiment of the present invention, the air chambers of the multiple columns 31, crossbeams 32, inclined beams 33, and top ridge beam 34 are all interconnected. The connection method is, for example, by providing vent pipes or vents at the joints of each component. The components of the multiple columns 31, crossbeams 32, inclined beams 33, and top ridge beam 34 are connected by a sealed connection to form a continuous inflatable air chamber. Inflation can be performed on the entire structure of the multiple columns 31, crossbeams 32, inclined beams 33, and top ridge beam 34 via the inflation valve 4, making operation convenient.

[0042] like Figure 1 As shown, the tent fabric 1 covers the outside of the inflatable frame, forming a tent space that is closed on all sides; the tent fabric 1 is provided with an entrance door 11 for entering and exiting the tent space, and the edge of the entrance door 11 is connected to the tent fabric 1 by a zipper 13.

[0043] In a specific embodiment of the present invention, the supporting air cushion 2 is fixedly connected to the vehicle roof. The tent fabric 1 is detachably connected to the frame air column 3 and the supporting air cushion 2. The detachable connection is achieved, for example, by buckles, Velcro, or straps. The edges of the tent fabric 1 are equipped with strong webbing or Velcro, which match the connection points on the surface of the frame air column 3. The tent fabric 1 is provided with hooks or straps for connection to the frame air column 3; the bottom edge of the tent fabric 1 is connected to the side wall of the supporting air cushion 2 by Velcro or zipper, forming a sealed tent space. After installation, the tent fabric 1 is in a moderately tensioned state.

[0044] As a specific embodiment of the present invention, the supporting air cushion 2 and the skeleton air column 3 are made of existing materials such as TPU, PVC or rubber.

[0045] As a specific embodiment of the present invention, the tent fabric 1 uses existing materials and includes an outer waterproof layer. The tent fabric 1 is a polyester fiber fabric coated with a polyurethane waterproof layer.

[0046] As an optional embodiment, the outer layer of the tent fabric 1 is 420D-600D Oxford cloth, the middle layer is aluminum foil composite cotton / hollow cotton / insulation cotton, and the inner layer is polyester cotton fabric.

[0047] like Figure 1 As shown, an observation window 12 is provided on the tent fabric 1. The observation window 12 is made of a transparent material, such as TUP transparent film, PVC transparent soft rubber, or transparent EVA material. The observation window 12 is sewn onto the tent fabric 1. Optionally, the observation window 12 can be equipped with an openable and closable blackout curtain.

[0048] This application provides a method for setting up a fully inflatable rooftop tent to reduce working pressure, the method comprising:

[0049] Step S1: Securely install the roof tent onto the top of the vehicle.

[0050] Step S2: Inflate the support air cushion and the frame air column simultaneously through a single inflation valve.

[0051] A portable low-pressure air pump is used to inflate the support air cushion and the frame air column through a single inflation valve. The gas supplied by the portable low-pressure air pump flows freely through the connecting channel between the support air cushion and the frame air column, automatically balancing the internal pressure of both to the same working pressure.

[0052] In a preferred embodiment of the present invention, the inflation pressure is monitored in real time by a pressure monitoring device installed on the inflation valve, and inflation is automatically stopped when the pressure reaches a set threshold.

[0053] Step S3: Control the inflation pressure of the inflation valve within a predetermined range to inflate the support air cushion to form a sleep support platform, while the frame air column inflates to form the support frame of the tent space.

[0054] The predetermined range for the inflation pressure of the control valve is 4-8 psi; the thickness range of the support air cushion after expansion is 20-40 cm. Under low-pressure operation at 4-8 psi, the support air cushion provides the same support force and anti-bottoming performance as existing high-pressure thin air cushions through a thickness deformation of 20-40 cm.

[0055] The beneficial effects achieved by this application are as follows: (1) Users can complete the product assembly by inflating the inflatable frame with a single inflation valve, making the operation simpler.

[0056] (2) This application increases the height of the support air cushion after inflation to 20-40 cm, providing normal support of the rated load under a working pressure of 4-8 psi, and reducing the working pressure required for the support air cushion and the skeleton air column.
