[0015] Preferably, the specific steps of using the transformable RV include:

[0016] Step 1: When the RV needs to be used, both the left and right boxes are fixed by clamping the card plate and the side plate; the two boxes are installed on the outside of the main frame at the same time, or any one of them is installed on the outside of the main frame alone; after the card plate is clamped in the inside of the clamping groove, the card plate squeezes the ball bearings on the side, and the elastic telescopic column contracts under force, so that the card plate moves freely in the clamping groove, and the card plate contacts the ball bearings, and the ball bearings make the card plate stable during movement, and at the same time, the friction between the ball bearings and the card plate is reduced;

[0017] Step 2: After the cardboard is installed inside the card slot, the hydraulic column drives the push plate to move toward the cardboard until the push plate abuts against the cardboard. The cardboard is stable inside the card slot, and the movable push plate and ball bearings are adapted to the installation of cardboards of different sizes; when the push plate moves toward the cardboard, the ball bearings pass through the perforations without affecting the normal movement of the push plate; after the push plate shrinks and detaches from the cardboard, the ball bearings protrude from the perforations and contact the cardboard;

[0018] Step 3: After the box is installed, when a larger space is needed for use, unfold the box. When the left box is unfolded, first move the first top plate upward, and the first top plate rotates upward driven by the third and fourth pneumatic telescopic rods on both sides, until the first top plate rotates to a preset position; then pull the first bottom plate downward, and the first bottom plate rotates at the bottom of the first vertical plate until the first bottom plate is horizontal; then pull the first front wall plate upward, and the bottom of the first front wall plate rotates around the first bottom plate until the top of the first front wall plate and the first limit position at the bottom end of the first top plate are aligned. The hinge is connected, and the first front wall panel supports the first top panel at the bottom; then the first left wall panel and the first right wall panel are pulled outward, and the ends of the first left wall panel and the first right wall panel are abutted against the side surfaces of the first front wall panel; then the two sides of the first bottom panel are plugged and fixed with the first pin and the second pin; the first pin extends from the inside of the first bottom panel to the inside of the first right wall panel and the first front wall panel; one end of the second pin extends from the inside of the first bottom panel to the inside of the first left wall panel and the first front wall panel; the right side box can be unfolded and used normally according to the unfolding method of the left side box.

[0019] Beneficial effects of the present invention:

[0020] 1. By setting a snap-in groove on one side of the side panel, when the RV needs to be used, the left and right boxes can be fixed to the side panel through the card plate. The two boxes can be installed on the outside of the main frame at the same time, or they can be installed on the outside of the main frame separately, which can be selected according to actual needs. After the card plate is snapped into the inside of the snap-in groove, the card plate squeezes the ball bearings on the side, which in turn causes the elastic telescopic column to be subjected to pressure. The elastic telescopic column shrinks under the force, so that the card plate can move freely inside the snap-in groove, and the card plate contacts the ball bearings. The ball bearings can make the card plate more stable during movement. At the same time, the friction between the ball bearings and the card plate is reduced, and the card plate and the ball bearings are not easily damaged. The card plate can move freely inside the snap-in groove, and installation and disassembly are convenient and quick.

[0021] 2. By installing a movable push plate inside the card slot, after the card is installed inside the card slot, the hydraulic column can drive the push plate to move toward the card until the push plate can stably contact the card, so that the card is not easy to shake inside the card slot, and the stability is better. In addition, the movable push plate and ball bearing can adapt to the installation of card plates of different sizes, and the adaptability is better. When the push plate moves toward the card plate, the ball bearing passes through the perforation, which does not affect the normal movement of the push plate. After the push plate shrinks and detaches from the card plate, the ball bearing protrudes from the perforation and contacts the card plate.

[0022] 3. After installing two boxes, when a large space is needed for use after the boxes are installed, the boxes are unfolded. Now take the left box as an example for unfolding. First, move the first top plate upward, and the first top plate rotates upward under the drive of the third and fourth pneumatic telescopic rods on both sides. Until the first top plate rotates to a preset position, generally stop rotating after rotating 90 degrees. Then pull the first bottom plate downward, and the first bottom plate rotates at the bottom of the first vertical plate until the first bottom plate is horizontal. Then pull the first front wall plate upward, and the bottom of the first front wall plate rotates around the first bottom plate until the top of the first front wall plate is connected to the first limit hinge at the bottom of the first top plate, and the first front wall plate supports the first top plate at the bottom. Then pull the first left wall plate and the first right wall plate outward, and the ends of the first left wall plate and the first right wall plate are both in contact with the side of the first front wall plate. Then use the first latch and the second latch to plug and fix the two sides of the first bottom plate. The first latch extends from the inside of the first bottom plate to the inside of the first right wall plate and the first front wall plate. One end of the second latch extends from the inside of the first bottom plate to the inside of the first left wall panel and the first front wall panel. The first left wall panel, the first front wall panel and the first right wall panel can all be stably fixed, and are not prone to shaking during use, nor will they tip over. The entire left side box is fully unfolded and can be used normally. Multiple iron hinges are used, and the space is greatly expanded through different degrees of wall panel push-pull folding, giving users a lot of space to meet the needs of multiple people. And after the folding wall panels expanded on the outside 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 accommodation occasions, and can be transformed in various internal ways 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.

The snap-in groove 26 facilitates the installation and disassembly of the snap-in plate 32, and thus facilitates the installation and disassembly of the box body.

[0043] As a technical optimization solution of the present invention, a push plate 28 is vertically installed inside the card slot 26, and several hydraulic columns 27 are installed between one side of the push plate 28 and the inner wall of one side of the card slot 26, and an elastic telescopic column 31 is installed between two adjacent hydraulic columns 27, and a ball 30 is installed at the other end of the elastic telescopic column 31. A perforation 29 is provided at the position corresponding to the push plate 28 and the ball 30. After the card plate 32 is carded into the card slot 26, the card plate 32 squeezes the ball 30 on the side, thereby causing the elastic telescopic column 31 to be compressed. The elastic telescopic column 31 is forced to shrink, so that the card plate 32 can move freely inside the card slot 26, and the card plate 32 contacts the ball 30.

The card plate 32 can move freely inside the card slot 26, and the installation and disassembly are convenient and quick.

[0044] As a technical optimization solution of the present invention, the specific steps of using the transformable RV include:

[0045] Step 1: When the RV needs to be used, both the left and right boxes are fixed to the side panels 21 through the clamping plate 32; the two boxes are installed on the outside of the main frame 20 at the same time, or any one of them is installed on the outside of the main frame 20 alone; after the clamping plate 32 is clamped in the inside of the clamping groove 26, the clamping plate 32 squeezes the ball 30 on the side, and the elastic telescopic column 31 is forced to shrink, so that the clamping plate 32 moves freely in the clamping groove 26, and the clamping plate 32 contacts the ball 30, and the ball 30 makes the clamping plate 32 stable during movement, and at the same time the friction between the ball 30 and the clamping plate 32 is reduced;

[0046] Step 2: After the card plate 32 is installed inside the card slot 26, the hydraulic column 27 drives the push plate 28 to move toward the card plate 32 until the push plate 28 abuts against the card plate 32. The card plate 32 is stable inside the card slot 26, and the movable push plate 28 and the ball 30 are adapted to the installation of card plates 32 of different sizes; when the push plate 28 moves toward the card plate 32, the ball 30 passes through the through hole 29 without affecting the normal movement of the push plate 28; after the push plate 28 shrinks and detaches from the card plate 32, the ball 30 protrudes from the through hole 29 and contacts the card plate 32;

[0047] Step 3: After the box is installed, when a larger space is needed for use, unfold the box. When the left box is unfolded, first move the first top plate 1 upward, and the first top plate 1 rotates upward driven by the third pneumatic telescopic rod 24 and the fourth pneumatic telescopic rod 25 on both sides; until the first top plate 1 rotates to a preset position; then pull the first bottom plate 2 downward, and the first bottom plate 2 rotates at the bottom of the first vertical plate 7 until the first bottom plate 2 is horizontal; then pull the first front wall panel 3 upward, and the bottom of the first front wall panel 3 rotates around the first bottom plate 2 until the top of the first front wall panel 3 and the first limit hinge at the bottom end of the first top plate 1 are interlocked. 10 is connected, and the first front wall panel 3 supports the first top panel 1 at the bottom; then the first left wall panel 5 and the first right wall panel 4 are pulled outward, and the ends of the first left wall panel 5 and the first right wall panel 4 are abutted against the side surfaces of the first front wall panel 3; then the first latch 8 and the second latch 9 are used to plug and fix the two sides of the first bottom panel 2; the first latch 8 extends from the inside of the first bottom panel 2 to the inside of the first right wall panel 4 and the first front wall panel 3; one end of the second latch 9 extends from the inside of the first bottom panel 2 to the inside of the first left wall panel 5 and the first front wall panel 3; the right side box can be unfolded and used normally according to the unfolding method of the left side box.

[0048] When the present invention is in use, when the RV needs to be used, the left and right boxes are both fixed to the side panels 21 by the clamping plate 32. The two boxes can be installed on the outside of the main frame 20 at the same time, or they can be installed on the outside of the main frame 20 separately, which can be selected according to actual needs. After the clamping plate 32 is clamped in the inside of the clamping groove 26, the clamping plate 32 squeezes the ball 30 on the side, thereby causing the elastic telescopic column 31 to be subjected to pressure, and the elastic telescopic column 31 is forced to shrink, so that the clamping plate 32 can move freely in the clamping groove 26, and the clamping plate 32 contacts the ball 30, and the ball 30 can make the clamping plate 32 more stable during movement, and at the same time, the friction between the ball 30 and the clamping plate 32 is reduced, and the clamping plate 32 and the ball 30 are not easy to be damaged. The clamping plate 32 can move freely in the inside of the clamping groove 26, and the installation and disassembly are convenient and quick.

[0049] After the card plate 32 is installed inside the card slot 26, the hydraulic column 27 drives the push plate 28 to move toward the card plate 32 until the push plate 28 can stably abut against the card plate 32, so that the card plate 32 is not easy to shake inside the card slot 26, and the stability is better. In addition, the movable push plate 28 and the ball 30 can adapt to the installation of card plates 32 of different sizes, and the adaptability is better. When the push plate 28 moves toward the card plate 32, the ball 30 passes through the through hole 29, which does not affect the normal movement of the push plate 28. After the push plate 28 shrinks and detaches from the card plate 32, the ball 30 protrudes from the through hole 29 and contacts the card plate 32.

[0050] After the box is installed, when a large space is needed for use, the box is unfolded. Now take the left box as an example for unfolding. First, move the first top plate 1 upward, and the first top plate 1 rotates upward under the drive of the third pneumatic telescopic rod 24 and the fourth pneumatic telescopic rod 25 on both sides. Until the first top plate 1 rotates to a preset position, generally rotate 90 degrees and stop rotating. Then pull the first bottom plate 2 downward, and the first bottom plate 2 rotates at the bottom of the first vertical plate 7 until the first bottom plate 2 is horizontal. Then pull the first front wall plate 3 upward, and the bottom of the first front wall plate 3 rotates around the first bottom plate 2 until the top of the first front wall plate 3 is connected to the first limit hinge 10 at the bottom of the first top plate 1, and the first front wall plate 3 supports the first top plate 1 at the bottom. Then pull the first left wall plate 5 and the first right wall plate 4 outward, and the ends of the first left wall plate 5 and the first right wall plate 4 are both abutted against the side of the first front wall plate 3. Then use the first latch 8 and the second latch 9 to plug and fix the two sides of the first bottom plate 2. The first latch 8 extends from the inside of the first bottom plate 2 to the inside of the first right wall plate 4 and the first front wall plate 3. One end of the second latch 9 extends from the inside of the first bottom plate 2 to the inside of the first left wall plate 5 and the first front wall plate 3. The first left wall plate 5, the first front wall plate 3 and the first right wall plate 4 can all be stably fixed, and are not prone to shaking or tipping over during use. The entire left side box is fully unfolded and can be used normally.

[0051] The right box can be unfolded and used normally according to the unfolding method of the left box. Multiple iron hinges are used, and the space is greatly expanded through different degrees of pushing, pulling and folding of the wall panels, which gives users a lot of space and can meet the needs of multiple people. After the folding wall panels expanded on the outside 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 accommodation occasions. Various internal modifications can be carried out 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.
