[0018] Step 1: When the entire RV needs to be used, the push-pull box body and the folding box body are unfolded to increase the space of the entire RV; when the push-pull box body is unfolded, the gas inside the inflatable bag is discharged, and several first suction cups are separated from the side wall panels, and the first hydraulic column contracts, driving the second suction cups to separate from the side wall panels; pull the first bottom plate to rotate outward until the first bottom plate is horizontal, and the slide rail on the upper part of the support arm is flush with the slide rail on the upper part of the main frame; several second pneumatic telescopic rods extend downward until they contact the ground, and several second pneumatic telescopic rods support the support arm from the bottom, pushing the push-pull box body to move toward one end of the second pneumatic telescopic rod until the push-pull box body moves to a preset position; several second hydraulic columns extend downward, driving the second suction cup at the bottom to bond with the top of the support arm;

[0019] The second step is to pull the second bottom plate downwards and the second bottom plate rotates at the bottom of the vertical plate until the second bottom plate is in a horizontal state; then the second front wall plate is pulled upwards and the bottom of the second front wall plate rotates around the second bottom plate until the top of the second front wall plate is connected with the limiting hinge at the bottom end of the second bottom plate, and the second front wall plate supports the second bottom plate at the bottom; then the left wall plate and the right wall plate are pulled outwards, and the ends of the left wall plate and the right wall plate are both in contact with the side surfaces of the second front wall plate; then the two sides of the second bottom plate are fixed with the first latch and the second latch; the first latch extends from the inside of the second bottom plate to the inside of the left wall plate and the second front wall plate; one end of the second latch extends from the inside of the second bottom plate to the inside of the right wall plate and the second front wall plate; the folding box can be unfolded and used normally;

[0020] Step three: When the RV needs to be moved, the push-pull box is pushed to one side of the main frame and the folding box is folded and stored to reduce the volume of the main frame; when the push-pull box is stored, several second hydraulic columns contract upward to drive the second suction cup to detach from the support arm. After the push-pull box moves and is connected to the outside of the main frame, air is filled into the inside of the airbag, and the airbag abuts against the side wall panel on one side, and several first suction cups are bonded to the side wall panel. The first hydraulic column extends to drive the second suction cup at the end to bond to the side wall panel; when the folding box is stored, the first pin and the second pin are pulled out, and the second front wall panel is pushed, and the second top panel, the right wall panel, the left wall panel and the second bottom panel are folded and stored on one side of the vertical panel.

[0021] Beneficial effects of the present invention:

[0022] 1. By installing a push-pull box on one side of the main frame, when the entire RV needs to be used, the push-pull box and the folding box can be unfolded for comprehensive use, thereby increasing the space of the entire RV. When the push-pull box is unfolded, the gas inside the inflatable bag is discharged, and several first suction cups are separated from the side wall panels. The first hydraulic column contracts, driving the second suction cup to separate from the side wall panels. Pull the first bottom plate outward until the first bottom plate is horizontal, and the slide rail on the upper part of the support arm can be flush with the slide rail on the upper part of the main frame. Several second pneumatic telescopic rods extend downward until they contact the ground, and several second pneumatic telescopic rods support the support arm from the bottom, so that the first bottom plate is more stable during use and is not prone to shaking. Push the push-pull box to move toward one end of the second pneumatic telescopic rod until the push-pull box moves to a preset position. Several second hydraulic columns extend downward, driving the second suction cup at the bottom to bond with the top of the support arm, so that the push-pull box can be parked stably and is safer during use.

[0023] 2. By installing the folding box body on the other side of the main frame, when the folding box body is unfolded, the second top plate can be moved upward, and the second top plate is rotated upward under the drive of the first pneumatic telescopic rods on both sides; until the second top plate is rotated to a preset position; then the second bottom plate is pulled downward, and the second bottom plate is rotated at the bottom of the vertical plate until the second bottom plate is in a horizontal state; then the second front wall plate is pulled upward, and the bottom of the second front wall plate is rotated around the second bottom plate until the top of the second front wall plate is connected with the limit hinge at the bottom end of the second bottom plate, and the second front wall plate supports the second bottom plate at the bottom; then the left wall plate and the right wall plate are pulled outward, and the ends of the left wall plate and the right wall plate are both abutted against the side surfaces of the second front wall plate; then the two sides of the second bottom plate are plugged and fixed with the first latch and the second latch; the first latch extends from the inside of the second bottom plate to the inside of the left wall plate and the second front wall plate; one end of the second latch extends from the inside of the second bottom plate to the inside of the right wall plate and the second front wall plate; the folding box body can be unfolded and used normally.

[0024] 3. When the RV needs to be moved, push the push-pull box to one side of the main frame and fold the folding box to store it, reducing the volume of the main frame. When the push-pull box is stored, several second hydraulic columns shrink upward, driving the second suction cup to detach from the support arm. After the push-pull box moves and snaps onto the outside of the main frame, the inside of the airbag is filled with air, and the airbag abuts against the side wall panel on one side, and several first suction cups are bonded to the side wall panel. The first hydraulic column extends and drives the second suction cup at the end to bond to the side wall panel, which can fully fix the push-pull box and make it more secure after storage. The RV is not prone to noise during driving. At the same time, the airbag has a buffering performance, which can prevent the push-pull box from being damaged by impact.

[0025] 4. One side adopts the pulley guide push-pull type, and the other side adopts multiple iron hinges. Through the push-pull and folding of the wall panels to different degrees, the space is greatly expanded, giving users a lot of space to meet the needs of multiple people. And after the left side is folded up and the folding wall panels expanded on the right side are stored, the volume during consignment can be reduced, and the RV is also more convenient and quick when turning. It can be widely used in RV hotels, personal travel, government epidemic prevention, emergency rescue and other occasions. It can be transformed into a variety of internal places to meet the needs of different occasions, especially to meet the needs of government epidemic prevention, and can be used in hospitals as isolation wards.
