Based on a car chassis, it integrates living facilities such as bedrooms, kitchens, and bathrooms, providing basic home functions such as sleeping, cooking, and washing.
[0003] Most RVs currently use mechanical linkage-type lifting roof mechanisms, which require the operation of multiple locking mechanisms and support components. The operation steps are cumbersome and laborious, and it is difficult for a single person to quickly complete the lifting and folding of the roof. To address this, we propose an air-supported RV inflatable lifting roof device. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an air-supported RV inflation and lifting device, which solves the problem that most RVs currently use mechanical linkage lifting mechanisms, which require the operation of multiple locking mechanisms and support components, making the operation cumbersome and laborious, and difficult for a single person to quickly complete the lifting and folding of the roof.

A protective rope 31 is fixedly connected to the surface of the base 1, and one end of the protective rope 31 is fixedly connected to the surface of the control bar 32 to limit the position of the air film body 26. The lifting and storage are efficient and convenient. The entire process of inflation and deflation and locking and unlocking is automatically controlled by the control unit 29. No manual force is required. The operation is simple and the response is fast, which greatly reduces the user threshold. The air film body 26 provides flexible lifting power to avoid damage to the device caused by hard impact. It effectively prevents the air film body 26 from deforming under long-term load and takes into account both the gentleness of lifting and the structural stability after unfolding.
[0022] The base 1 contains a control unit 29 and an inflation locking unit 27.
[0023] Among them, an elastic rope 28 is fixedly connected to the inner wall of the base 1. The end of the elastic rope 28 away from the base 1 is fixedly connected to the surface of the air film body 26, which is used to recycle the air film body 26 when storing the top cover 21.
[0024] The top cover 21 is equipped with side air membranes 24 on both sides. Compared with the traditional mechanical pop-up structure, the air membrane body 26 is lighter and has a smaller storage volume, which can save interior space of the RV. Moreover, the design of the side air membrane 24 does not affect the view when using it, thus taking into account both practicality and space utilization.

[0026] The upper surface of the stabilizing seat 37 is fixedly connected to the air outlet seat 38, the interior of the air outlet seat 38 is connected to the top cover 21, the inner wall of the air outlet seat 38 is equipped with a filter screen 39, the upper surface of the stabilizing seat 37 is fixedly connected to the protective cover 310, the protective cover 310 is fitted on the air outlet seat 38, and a gap is left between one side of the protective cover 310 and the stabilizing seat 37 for air circulation.
[0027] The upper surface of the stabilizing base 37 is fixedly connected to a guide sleeve 36. One side of the guide sleeve 36 is fixedly connected to the surface of the air outlet base 38. The inner wall of the guide sleeve 36 is connected to the interior of the air outlet base 38. A sealing plate 35 is slidably inserted in the guide sleeve 36. The sealing plate 35 is adapted to the interior of the air outlet base 38 and is used to control the opening and closing of the air outlet base 38. The protective component 3 and the top cover 21 are linked. When the top is raised, the air outlet base 38 is automatically opened to ensure air pressure balance. When stored, the sealing plate 35 is closed simultaneously to isolate debris. With the protection of the protective cover 310 and the filter screen 39, the air pressure of the air film body 26 is stabilized during operation, and the cleanliness and sealing of the device are improved.
[0028] Among them, a linkage rod 34 is fixedly connected to the upper surface of the control bar 32. The linkage rod 34 is L-shaped, and one end of the linkage rod 34 is fixedly connected to one side of the sealing plate 35. When the control bar 32 moves, the linkage rod 34 and the sealing plate 35 are moved synchronously.
[0029] The base 1 has four symmetrically arranged assembly components 4 on its surface. The assembly components 4 are securely connected to the vehicle body through multiple fixing devices. Meanwhile, the protective rope 31, elastic rope 28 and other components assist in limiting and retrieving, preventing the components from loosening or shaking during driving, thus improving the driving safety and service life of the device.
[0030] The assembly component 4 includes a positioning groove 41, which is located on the side of the base 1. A mounting bracket 42 is slidably connected in the positioning groove 41. The mounting bracket 42 is L-shaped, and a mounting bolt 44 is threaded into the inner wall of the mounting bracket 42. A locking bolt 43 is threaded into the inner wall of the base 1. One end of the locking bolt 43 is connected to the positioning groove 41 and is used to hold the mounting bracket 42 in place.
[0031] Working principle of the invention: After the vehicle is parked, the control unit 29 first triggers the inflation locking unit 27 to release the lock. At the same time, the locking bolt 43 of the assembly component 4 maintains a stable connection between the mounting bracket 42 and the RV body. Subsequently, the control unit 29 starts the inflation system. Gas is injected into the air film body 26 through the through hole 25 of the base 1. After the air film body 26 expands, it pushes the top cover 21 upward. The top cover 21 rotates around the pivot 23 of the support frame 22. When the top cover 21 rises, the air film body 26 supports and squeezes the protective rope 31. The protective rope 31 then pulls the control bar 32. The control bar 32 pulls the pull rod 33 to compress the slider 311 in the stabilizer 37 and the spring 312. At the same time, L The linkage rod 34 moves with the control bar 32, pulling the sealing plate 35 to slide along the guide sleeve 36 to open the air outlet seat 38, allowing the air inside the top cover 21 to circulate through the gap between the air outlet seat 38 and the protective cover 310, maintaining the air pressure balance inside and outside the air film body 26. When the pressure of the air film body 26 reaches the preset value of the control unit 29, the inflation system stops working. With the expansion support force of the air film body 26, the top cover 21 remains in the unfolded state, and the lifting is completed. During the storage phase, the control unit 29 initiates the deflation procedure, and the gas inside the air film 26 is discharged. The elastic rope 28 in the base 1 simultaneously pulls the air film 26 to contract in order to assist in the recycling. After the air film 26 is deflated, the top cover 21 returns to its original position around the pivot 23 under its own weight. At the same time, the protective rope 31 relaxes, the spring 312 pushes the slider 311 to return to its original position, and the control bar 32 drives the sealing plate 35 to close the air outlet seat 38 through the linkage rod 34 to prevent external debris from entering the top cover 21. When the top cover 21 is completely returned to its original position, the control unit 29 detects that the pressure of the air film 26 has dropped to a preset value and triggers the inflation locking unit 27 to lock it. Throughout the process, the control unit 29 monitors the pressure of the air membrane 26 and the status of the locking unit in real time, and automatically adjusts the inflation and deflation process. The air membrane 26 provides the lifting power, and the protective component 3 controls the opening and closing of the air outlet seat 38 in conjunction with the movement of the top cover 21, taking into account both air circulation during lifting and sealing protection after storage. The assembly component 4 ensures a stable connection between the device and the RV body through the cooperation of the positioning groove 41, the mounting bracket 42 and the locking bolt 43.
