The bottom of the rear cover is provided with wheels for driving the rear chamber to extend and retract in the X direction. The oxygen chamber is equipped with a folding recliner, which includes a fixed part, a rotating part, and a walking part arranged along the X-axis. The fixed part is fixedly connected to the bottom of the front chamber. The rotating part includes a rotating base and a first rotating part. The lower end of the first rotating part is connected to the bottom of the front chamber, and the upper end is rotatably connected to the rotating base, allowing the rotating base to have the freedom to flip forward and upward in the XZ plane. The walking part includes a walking base, a leveling seat, and a second rotating part. The lower end of the second rotating part is fixedly connected to the rear end of the telescopic support assembly via a walking leg, and the upper end is rotatably connected to the rear end of the walking base, allowing the walking base to have the freedom to flip backward and upward in the XZ plane. The rear end of the rotating part base and the front end of the walking base are connected via a third rotating part, with an initial hinge angle of A between them. The leveling seat is fixedly connected to the walking base via a support rod. When the folding recliner is unfolded, the leveling seat remains horizontal with the fixed part and the rotating part. The walking leg is composed of an upper leg and a lower leg that are connected together. The upper leg can move up and down along the lower leg to adjust the leg length.

2. The telescopic micro-pressure oxygen-enriched chamber according to claim 1, characterized in that: The first rotating part includes a first support and a first rotating shaft arranged along the Y direction. The first support includes two symmetrically arranged legs, which are respectively fixedly connected to the bottom of the front cabin. The first rotating shaft is fixedly connected to the front end of the rotating base. The two ends of the first rotating shaft are rotatably mounted between the two legs of the first support, so that the rotating part can flip forward and upward in the XZ plane. The second rotating part includes a second support and a second rotating shaft arranged along the Y direction. The second support includes two symmetrically arranged legs, which are respectively connected to the telescopic support assembly. The second rotating shaft is fixedly connected to the rear end of the walking base. The two ends of the second rotating shaft are rotatably mounted between the two legs of the second support, so that the rotating part can flip backward and upward in the XZ plane.

3. The telescopic micro-pressure oxygen-enriched chamber according to claim 1, characterized in that: The telescopic support assembly is an X-shaped telescopic frame, which includes n sets of X-shaped cross links, where n≥3. The two sets of cross links at the ends are fixedly connected to the front cabin and the rear cabin cover via the support base rod, respectively. The walking outriggers are fixed to both ends of the support base rod.

4. The telescopic micro-pressure oxygen-enriched chamber according to claim 1, characterized in that: The third rotating part is a T-shaped component, which includes a transverse connecting part and a longitudinal supporting part. The two ends of the transverse connecting part are respectively hinged to the rear end of the rotating part and the front end of the walking part via pin shafts. The initial hinge angle A formed by the rotating part and the walking part being hinged through the third rotating part is 165° to 175°. When the folding recliner is unfolded, the longitudinal supporting part is supported on the telescopic supporting assembly.

5. The telescopic micro-pressure oxygen-enriched chamber according to claim 1, characterized in that: A buffer spring is provided between the upper and lower support legs.

6. The telescopic micro-pressure oxygen-enriched chamber according to claim 1, characterized in that: A rotating bolt assembly is provided between the front and rear compartments. The rotating bolt assembly includes a long strip bolt arranged horizontally along the X direction. One end of the bolt is rotatably connected to the rear compartment cover. The front end of the bolt has a positioning notch, and a buckle is provided at the corresponding position on the rear side of the front compartment. When the rear compartment is retracted to its shortest state, the positioning notch and the buckle engage to lock and fix the rear compartment and the front compartment.

7. The telescopic micro-pressure oxygen-enriched chamber according to claim 1, characterized in that: The flexible shell has an accordion-style structure at its telescopic folds, with a fold depth of 50-80mm. Elastic ribs are provided on the inner side of the folds, and the elastic ribs are distributed at intervals along the X direction with a spacing of 150-200mm.

8. The telescopic micro-pressure oxygen-enriched chamber according to claim 1, characterized in that: The bottom of the front chamber is provided with at least two front chamber wheels, which are on the same horizontal plane as the traveling wheels. When the rear chamber is retracted into place, the front chamber wheels and the traveling wheels together form a support and movement assembly, which drives the oxygen chamber body to move along the horizontal plane.

9. The telescopic micro-pressure oxygen-enriched chamber according to claim 1, characterized in that: A connecting cloth is provided between the rear end of the fixed part and the front end of the rotating part. When the rotating part is laid flat, the connecting part is stretched flat along the X-axis.
