Description

Technical Field

[0001] This invention relates to a production and operating system for a two-story folding RV body, particularly a system for raising the second-floor rooms of an RV body, including a double-layer, double-switch folding body panel, a lifting side panel, a lifting roof, and a roller blind. This invention belongs to the field of RV production. Background Technology

[0002] Due to the limited space in RVs, technologies for expanding RV space, such as extending the cabin or using a pop-up roof, often rely on existing RV cabin insulation panels. However, single-layer insulation panels reduce the effectiveness of temperature insulation and heat preservation. Furthermore, the opening and closing of RV cabins enclosed by single-layer insulation panels offers limited living space, thus lowering the quality of RV life. Single-layer insulation panels also fail to integrate various materials, hindering the versatility of RV lifestyles. Therefore, a technology is needed to enhance the temperature insulation and heat preservation of a second-floor RV cabin, and to improve the overall RV lifestyle experience. Summary of the Invention

[0003] This invention provides a foldable, double-layered, double-switch operating system for a motorhome's second-floor cabin. The objective is to achieve the following technical effect: utilizing foldable, double-layered panels to insulate and maintain temperature, increasing the ease of opening and closing of the cabin enclosed by the insulated double-layered panels. The double-layered panels combine multiple materials, enhancing the user's versatility in motorhome living. This results in an additional double-layered, insulated cabin in the second-floor motorhome, thus enriching the user's motorhome lifestyle. The invention is implemented as follows: A lift-up canopy is installed on the upper part of the cabin roof panel, overlapping the cabin roof panel. The lift-up canopy is raised or lowered by a lifting rod. The lift-up canopy includes folding panels, hinged to the lift-up canopy, allowing for folding and unfolding. These folding panels are composed of two types of panels stacked into a double-layered, more insulated double-floor cabin. When the user parks the motorhome, [the system allows for easy access to the cabin]. The user issues a command to raise the second-floor RV cabin, which is transmitted to the RV's processor via circuitry or communication network equipment. The processor controls a lifting rod to raise the roof. The user then sends a command to unfold the folding panels that are folded together with the roof. The processor controls a telescopic push rod or cable to unfold the folding panels. The unfolded folding panels, together with the roof and the RV roof, form a closed second-floor cabin. The user can further unfold the double-layered folding panels, again controlled by the processor, using a telescopic push rod or cable to unfold the two panels from their folded state. The unfolded folding panels create a sunroom or ventilated terrace, similar to windows, in the second-floor cabin. The user can also retract the folding panels, closing them to their folded state. The processor controls a telescopic push rod or cable to retract the two panels, creating a more insulated and enclosed second-floor cabin.

[0004] The materials of the folding panel include the main frame, solar panels, transparent panels, insulation panels, and the materials of roller shutters or roller blinds.

[0005] The folding panel is hinged to the pop-up roof, allowing it to be folded up or unfolded. The double-layer folding panel is made of two materials: a solar panel and a transparent sheet. The main frame has a U-shaped structure. The solar panel is hinged to the side of the main frame facing outwards from the RV, while the transparent sheet is hinged to the side facing inwards from the RV. When the user unfolds the double-layer folding panel, the processor controls a telescopic push rod to extend the solar panel outwards from the pop-up roof. After unfolding, it extends horizontally with the pop-up roof, creating an optimal angle for receiving sunlight to generate green energy through solar power, supplementing the RV's electricity needs. The other... As the solar panels unfold, the transparent panels form a transparent window on the second floor of the RV, allowing users to live and relax in a sunroom without being disturbed by wind or rain, and enjoy the scenery outside. Furthermore, users can control a telescopic push rod or rope via a processor to fold the transparent panels inwards towards the RV's pop-up roof, creating a ventilated terrace similar to a window on the second floor, where users can enjoy the breeze and scenery. When the two panels are folded up, they form a double-layered, more insulated, enclosed second-floor compartment.

[0006] The folding panels are hinged to the lifting roof, allowing them to be folded up or unfolded. The double-layer folding panels are made of either a roller blind or a transparent panel. The main frame has an F-shaped structure forming a U-shaped groove, with the roller blind moving along this groove. A hinged connection to the transparent panel is located on the side of the main frame facing inwards towards the RV. When the user unfolds the double-layer folding panels, the processor controls the motor inside the roller blind to retract it. As the roller blind retracts, the transparent panel forms a transparent window on the second floor of the RV, allowing the user to live and relax in a sunroom, unaffected by wind or rain, and enjoy the view. Furthermore, the user can manually push the transparent panel of the folding panels inwards towards the lifting roof, creating a ventilated terrace similar to a window on the second floor, allowing the user to enjoy the breeze and view the scenery. Finally, the user lowers the roller blind and transparent panel, closing the double-layer folding panels to form a more insulated and enclosed double-layer cabin on the second floor of the RV.

[0007] The double-layer folding panel is made of two materials: an insulating panel and a transparent panel. When the user unfolds the panel, the processor controls a telescopic push rod to extend the insulating panel outwards towards the RV's pop-up roof. Once unfolded, it expands horizontally with the roof, forming a sunshade or rain shelter. The transparent panel, as the insulating panel unfolds, becomes a transparent window on the second floor of the RV, allowing the user to live and rest in a room sheltered from the elements and enjoy the view. Furthermore, the user can control the telescopic push rod or rope to fold the transparent panel inwards towards the pop-up roof, creating a ventilated terrace similar to a window on the second floor, allowing the user to enjoy the breeze and scenery. When the user folds up the panel, the insulating and transparent panels close to form a double-layered structure, creating a more insulated and enclosed double-layered cabin on the second floor of the RV.

[0008] The folding panel includes a roller blind, a transparent panel, and a main frame; the transparent panel is hinged on the lifting canopy near the roller blind and can be folded up or unfolded.

[0009] The main frame of the folding panel is fixed on the lifting rod. As the lifting rod rises or falls, the main frame is provided with a U-shaped structure to form a U-shaped groove. The openings through which the lifting rod and the main frame pass when rising or falling through the box panel on the roof of the RV are the same shape as the main frame, so that the U-shaped groove of the main frame can rise or fall with the lifting rod.

[0010] The upper part of the roof panel of the RV is provided with a foldable panel. The foldable panel is hinged to the roof panel and is opened or folded by a telescopic push rod. When opened, the foldable panel and the RV roof form the second space of the RV.

[0011] The lifting canopy is stacked with the folding panels; lifting insulation panels are installed on the outer sides of the RV body panels, which are fitted onto the RV body panels. The insulation panels are raised or lowered by lifting push rods; the insulation panels are raised along the slide rails by lifting push rods, the lifting canopy is raised by lifting rods, and the folding panels stacked with the lifting canopy unfold and come into contact with the insulation panels, forming a closed double-layer box room on the second floor of the RV;

[0012] The main frame of the double-layer folding panel is designed as an F-shaped structure, a convex structure, a U-shaped structure, or a square structure to facilitate the folding or stacking of the two types of panels together. Attached Figure Description

The folding panel 2 without the protrusion 205 and hinge 4 is folded first, and the folding panel 2 with the protrusion 205 and hinge 4 is folded second. The upper part of the box panel 101 of the RV roof is connected to the insulation board 204 by hinge 4. The insulation board 204 is folded up or unfolded by the telescopic push rod 302 according to the hinge 4. The box panel 101 has two sides with protrusions 205 that are connected to the insulation board 204 by hinge 4. The protrusions 205 provide space for placing the stacked insulation board 204, which is convenient for folding. Figure 4 A1-A1 Figure 5 As shown in A2-A2, the insulation panels 204 on the four sides are stacked together. The insulation panels 204 without the protrusions 205 and the hinges 4 are folded first, and the insulation panels 204 with the protrusions 205 and the hinges 4 are folded again. The folded panels 2 or insulation panels 204 are stacked together as the lifting roof 1 descends and overlaps with the roof of the RV to form the standard RV exterior dimensions.

[0033] Figure 1A in the diagram is a schematic of the communication network circuit control operating system. The user issues commands to raise or lower, unfold or retract the second-floor RV cabin's lifting ceiling 1, folding panels 2, solar panels 203, transparent panels 202, insulation panels 204, and roller blind 206. These commands are transmitted to the processor on the RV via circuitry or communication network equipment. The processor controls the electric mechanism to raise or lower, unfold or retract the second-floor RV cabin's lifting ceiling 1, folding panels 2, solar panels 203, transparent panels 202, insulation panels 204, and roller blind 206. This controls the diverse use and effects of the second-floor RV cabin for various lifestyles.

[0034] Figure 2 The RV roof's lifting canopy 1 is raised by the lifting rod 3 of the lifting mechanism 301; the folding panel 2 installed on the lifting canopy 1 is folded up by the telescopic rope 303 when it is folded up, and unfolded by the extension of the telescopic rope 303 when it is unfolded, relying on the gravity of the folding panel 2; the insulation board 204 on the upper part of the RV roof's box panel 101 is unfolded by the telescopic push rod 302; the unfolded folding panel 2 or insulation board 204, together with the lifting canopy 1 and the box panel 101, constitute the second room of the RV; the box panel 101 on the RV roof is provided with an opening 7 for personnel to enter and exit, facilitating users to enter and exit the second room of the RV;

[0035] Figure 3 , Figure 4 , Figure 5 , Figure 6 The folding panel 2 shown includes materials for solar panel 203, transparent panel 202, insulation panel 204 and main frame 201, which are folded and stacked together to form a double-layer insulated foldable panel 2. Figure 4 A1-A1 in the text refers to the insulation board 204 being unfolded or folded up by the telescopic push rod 302; Figure 3 AA in Figure 5 A2-A2 in Figure 6 The main frame 201 described in A3-A3 has a U-shaped structure. The solar panel 203 is connected to the main frame 201 on the side of the RV with a hinge 4. The solar panel 203 is opened or closed by a telescopic push rod 302. The transparent panel 202 is connected to the main frame 201 on the side of the RV with a hinge 4. The transparent panel 202 can be opened or closed manually. Figure 5A2-A2 in the diagram is an enlarged side view of the rear sectional view of the RV. The enlarged view clearly shows the structure of the folding panel 2. The folding panel 2 is driven by the telescopic rope 303 and is folded or unfolded according to the hinge 4 connected to the lifting roof 1. The insulation board 204 on the upper part of the box panel 101 of the RV roof is folded or unfolded by the telescopic push rod 302. The unfolded folding panel 2 or insulation board 204, together with the lifting roof 1 and the box panel 101, constitute the second room of the RV. Figure 6 Figure A3-A3 shows a schematic diagram of the unfolded solar panel 203 and transparent panel 202 of the folding assembly 2. The unfolded folding assembly 2 contacts the insulation panel 204, forming the second floor of the RV. After the telescopic rope 303 connected to the folding assembly 2 is removed and retracted, the solar panel 203 is pushed outwards by the telescopic push rod 302, extending horizontally with the RV's lifting roof 1. The extended solar panel 203 forms an optimal angle for receiving sunlight, generating green energy through solar power to supplement the RV's electricity needs. The other transparent panel 202, along with the unfolded solar panel 203... When opened, the transparent panel 202 forms a transparent window on the second floor of the RV, allowing users to live and rest in the sunroom through the transparent window, unaffected by wind and rain, and to enjoy the scenery outside. Furthermore, the user can push the transparent panel 202 inwards to fold and unfold it into the RV's pop-up roof 1, creating a ventilated terrace similar to the window on the second floor, where users can enjoy the breeze and scenery. When the user folds up the solar panel 203 and the transparent panel 202, they are closed in a stacked state, forming a more insulated and enclosed double-layered container room on the second floor of the RV.

[0036] In this embodiment, the lifting roof 1 is equipped with folding panels 2, which are connected to the lifting roof 1 via hinges 4, allowing them to be folded up or unfolded. The double-layer folding panels 2 are made of either insulation board 204 or transparent board 202. The main frame 201 has a U-shaped structure. The insulation board 204 is connected to the main frame 201 on the side facing outwards from the RV via hinges 4, and is unfolded or folded by a telescopic push rod 302. The transparent board 202 is connected to the main frame 201 on the side facing inwards from the RV via hinges 4, and is unfolded or folded by a telescopic push rod 302 or a telescopic rope 303. When the user unfolds the double-layer folding panels 2, the processor controls the telescopic push rod 302 to unfold the insulation board 204 outwards from the RV's lifting roof 1. After unfolding, it extends horizontally with the lifting roof 1, expanding the insulation board... The insulating panel 204 forms a sunshade or a rain shelter to block sunlight. The other transparent panel 202, as the insulating panel 204 unfolds, forms a transparent window on the second floor of the RV, allowing users to live and rest in a room with a transparent window, unaffected by wind and rain, and to enjoy the scenery outside. Furthermore, the user controls the telescopic push rod 302 or telescopic rope 303 via the processor to fold the transparent panel 2 inwards towards the RV's lifting roof 1, creating a ventilated terrace similar to a window on the second floor of the RV, allowing users to enjoy the breeze and scenery outside. When the user folds up the insulating panel 204 and the transparent panel 2, they form a double-layered structure, creating a more insulated and enclosed double-layered cabin on the second floor of the RV.

[0037] This implementation example Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, Figure 7 Figure 8 Figure 9 The driver's cab 6 of the RV has a cab-over compartment. The RV's lift-up roof 1 is connected to the folding panel 2 by a hinge 4 and folds together. The lift-up roof 1 has a protrusion 205 at the hinge 4 connection point to support the space for placing the folded panel 2, which is convenient for folding. Insulation panels 204 are provided on the outer sides of the RV body panel 101 and are fitted onto the RV body panel 101. The insulation panels 204 are raised or lowered by the lifting push rod 302. Figure 7 The lifting canopy 1 and the lifting insulation board 204 are driven down by the lifting rod 3 and the lifting push rod 302, forming the standard external dimensions of the RV with the RV body panel 101; Figure 8The lifting canopy 1 is lifted by the lifting rod 3, and the insulation board 204 is lifted by the lifting push rod 302 along the slide rail 5. The folding panel 2, which is stacked with the lifting canopy 1, unfolds and comes into contact with the insulation board 204 to form a closed double-layer box room on the second floor of the RV. Figure 9 The lifting canopy 1 mentioned in BB is raised by the lifting rod 3, and the insulation board 204 is raised by the lifting push rod 302 along the slide rail 5. The folding panel 2 is folded and overlapped with the lifting canopy 1 by the telescopic rope 303. After folding, it and the insulation board 204 form a ventilation terrace like the window of the second floor room of the RV. Users can enjoy the breeze and the scenery outside in the second floor room of the RV.

[0038] Figure 10 B1-B1 in Figure 11 B2-B2 in Figure 12 As shown in B3-B3, the folding panel 2 is composed of materials including a roller shutter 206, a transparent panel 202, and a main frame 201, forming a double-layered, heat-insulating, foldable folding panel 2. The folding panel 2, including the main frame 201, is connected to the lifting roof 1 via a hinge 4 and is folded and stacked by a telescopic rope 303. The main frame 201 has an F-shaped structure, forming a U-shaped groove 207. The roller shutter 206 is located on the main frame 201 near the contact point with the lifting roof 1, and the roller shutter 206 moves along the U-shaped groove 207. The transparent panel 202 is located on the main frame 201 and connected to the RV interior side via a hinge 4, and the transparent panel 202 can be manually unfolded or retracted.

[0039] Figure 11 B2-B2 in the diagram is an enlarged side view of the rear sectional view of the RV, which clearly shows the structure of the folding panel 2. The folding panel 2 is driven by the telescopic rope 303 and folds or unfolds according to the hinge 4 connected to the lifting roof 1. Liftable insulation panels 204 are set on the outer side of the RV body panel 101 and are fitted onto the RV body panel 101. The insulation panels 204 are driven by the lifting push rod 302 to rise or fall according to the slide rail 5. When the folding panel 2, which is stacked with the lifting roof 1, unfolds and comes into contact with the insulation panels 204, it forms a closed double-layer box room on the second floor of the RV.

[0040] Figure 12The diagram shown in B3-B3 illustrates the retraction of the roller blind 206 and the unfolding of the transparent panel 2 in the folding assembly 2. The unfolded folding assembly 2 contacts the insulation panel 204, forming the second floor of the RV. The double-layered folding assembly 2 is made of two materials: a roller blind 206 and a transparent panel 202. When the user unfolds the double-layered folding assembly 2, the motor inside the roller blind 206 is controlled by a processor to retract and move along the U-shaped groove 207. The transparent panel 202, as the roller blind 206 retracts, also retracts... 2. A transparent window forms the second floor of the RV, allowing users to live and rest in the room with the transparent window, unaffected by wind and rain, and to enjoy the scenery outside. Furthermore, the user can push the transparent panel 202 to fold inwards towards the RV's lift-up roof 1, forming a ventilated terrace similar to the window in the second floor of the RV, allowing users to enjoy the breeze and scenery outside. The user can then lower the roller blind 206 and the transparent panel 202, closing them into a double-layered folding panel 2, forming a more insulated and enclosed double-layered container room on the second floor of the RV.

[0041] This implementation example Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 As shown, Figure 13 Figure 14 CC in Figure 15 In the C1-C1 section, insulation panels 204 are installed on the outer sides of the RV body panel 101, covering the upper part of the RV body panel 101. The insulation panels 204 are lifted by the lifting push rod 302 along the slide rail 5; the lifting canopy 1 is lifted by the lifting rod 302. The folding panel 2, comprising a roller blind 206, a transparent panel 202, and a main frame 201, forms a double-layer insulated folding panel 2. The main frame 201 is fixed to the lifting rod 3. As the lifting rod 3 rises or falls, the main frame 201 has a U-shaped groove 207. The roller blind 206 is located near the contact point between the main frame 201 and the lifting roof 1. The roller blind 206 moves and unfolds or retracts according to the U-shaped groove 207. A transparent panel 202 is hinged to the side of the main frame 201 facing inwards towards the interior of the RV. The transparent panel 202 can be manually folded and unfolded or retracted. The main frame 201 and the lifting rod 3 are fixed. When rising or falling, the opening through the RV roof panel 101 is the same shape as the main frame 201, facilitating the U-shaped groove 207 of the main frame 201 to rise or fall with the lifting rod 3.

[0042] Figure 16C2-C2 in the diagram is an enlarged side view of the rear sectional view of the RV, which clearly shows the structure of the folding panel 2. The folding panel 2 includes a roller blind 206, a transparent panel 202, and a main frame 201. The main frame 201 is fixed to the lifting rod 3. When the user unfolds the double-layered folding panel 2, the motor inside the roller blind 206 is controlled by the processor to unfold the roller blind 206. The roller blind 206 moves downward and unfolds according to the U-shaped groove 207 of the main frame 201. The transparent panel 202 is connected to the main frame 201 on the side of the RV interior via a hinge 4. The transparent panel 202 and the roller blind 206 form a double-layered insulated folding panel 2, which is in contact with the insulated panel 204, forming a closed double-layered box-like room on the second floor of the RV.

[0043] Figure 17 The diagram shown in C3-C3 illustrates the retraction of the roller blind 206 and the unfolding of the transparent panel 2 in the folding assembly 2. The user unfolds the double-layered folding assembly 2, and the motor inside the roller blind 206 is controlled by the processor to retract the roller blind 206, which moves along the U-shaped groove 207 to retract. As the roller blind 206 retracts, the transparent panel 202 forms a transparent window on the second floor of the RV, allowing the user to live and rest in the room with the transparent window, unaffected by wind and rain, and to enjoy the scenery outside. Furthermore, the user can push the transparent panel 202 of the folding assembly 2 inwards towards the RV's lifting roof 1, forming a ventilated terrace similar to a window on the second floor of the RV, allowing the user to enjoy the breeze and view the scenery outside.

[0044] The lifting canopy 1 is lowered by the lifting rod 3, and the insulation board 204 is lowered by the lifting push rod 302 along the slide rail 5, forming the standard RV dimensions with the RV body panel 101. During this process, the main frame 201 and the lifting rod 3 are fixed. First, the user controls the motor inside the roller blind 206 to roll up the roller blind 206 according to the U-shaped groove 207. Then, the user pushes the transparent board 202 to fold inward to the RV lifting canopy 1. After folding, the lifting canopy 1 driven by the lifting rod 3 of the fixed main frame 201 is free from obstacles between it and the RV body panel 101. The lifting rod 3 can lower the lifting canopy 1, and the insulation board 204 is lowered by the lifting push rod 302 along the slide rail 5, forming the standard RV dimensions with the RV body panel 101.

[0045] When two transparent panels 202 of the folding assembly 2 are stacked together, one of the transparent panels 202 is connected to the hinge 4 of the protrusion 205. The protrusion 205 provides space for placing the stacked transparent panels 202, which facilitates folding. The transparent panel 202 without the protrusion 205 is first folded into the space provided by the support, and the transparent panel 202 with the protrusion 205 is then folded, with the two transparent panels 202 stacked on top of each other.

[0046] The folding panel 2 includes a roller blind 206, a transparent panel 202, and a main frame 201. When the user unfolds the double-layered folding panel 2, the motor inside the roller blind 206 is controlled by the processor to unfold the roller blind 206. The roller blind 206 moves downward and unfolds according to the U-shaped groove 207 of the main frame 201. The transparent panel 202 is set on the lifting ceiling 1 and connected by a hinge 4. It fits against the roller blind 206 and can be folded up or unfolded.

[0047] The user unfolds the transparent panel 202, and the telescopic rope 303 is connected to the transparent panel 202. The user sends a command to control the telescopic rope 303 through the processor, which drives the transparent panel 202 of the folding assembly 2 to fold inward to the inside of the RV's lifting roof 1. After folding, it forms a ventilated terrace like a window in the second-floor room of the RV, where the user can enjoy the breeze and the scenery outside. The telescopic rope 303 extends and lowers the transparent panel 202, which unfolds downward under its own weight, forming a closed window box in the second-floor room of the RV.

[0048] The materials of the folding panel include solar panels, transparent panels, thermal insulation panels, and materials for roller shutters or roller blinds; in the embodiments, the installation positions of the materials can be interchanged according to actual needs.

[0049] The main frame can be designed like a window according to the size of the solar panel, transparent panel, insulation panel, and roller blind, with a window in the middle of the main frame of the long panel area.

[0050] The materials of the folding panel include solar panels, transparent panels, thermal insulation panels, and materials for roller shutters or roller windows. The materials are sealed with commonly used sealing materials. The sealing between the folding panel and the box panel, the lifting canopy, or the lifting rod also uses conventional sealing materials.

[0051] The insulation board includes materials capable of isolating the temperature of the space.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The folding panel is made of two kinds of boards stacked together to form a double-layer, more heat-insulating RV foldable double-layer box. When a user parks the RV, they issue a command to raise the second-floor RV cabin. This command is transmitted via circuitry or a communication network to a processor on the RV. The processor controls a lifting rod to raise the roof. The user then sends a command to unfold the folding panels that are folded together with the roof. The processor controls a telescopic push rod or rope to unfold these panels. The unfolded folding panels, together with the roof and the RV roof, form a closed second-floor cabin. The user can further unfold the double-layered folding panels, again using the processor to control the telescopic push rod or rope, moving the two panels from a folded state to an unfolded state. The unfolded folding panels create a sunroom or ventilated terrace, similar to windows, in the second-floor cabin. Finally, the user commands to retract the two panels back to a folded state, again using the processor to control the telescopic push rod or rope, retracting the two panels to form a more insulated, enclosed second-floor cabin.

The double-layer folding panel is made of two materials: a solar panel and a transparent sheet. The main frame has a U-shaped structure. The solar panel is hinged to the side of the main frame facing outwards from the RV, while the transparent sheet is hinged to the side facing inwards from the RV. When the user unfolds the double-layer folding panel, the processor controls a telescopic push rod to extend the solar panel outwards from the pop-up roof. After unfolding, it extends horizontally with the pop-up roof, creating an optimal angle for receiving sunlight to generate green energy through solar power, supplementing the RV's electricity needs. The other... The transparent panels, as the solar panels unfold, form a transparent window on the second floor of the RV. Users can live and relax in this sunroom, sheltered from wind and rain, and enjoy the scenery outside. Furthermore, users can control a telescopic push rod or rope via a processor to fold the transparent panels inwards towards the RV's pop-up roof, creating a ventilated terrace similar to a window on the second floor. Users can enjoy the breeze and scenery from inside. When the two panels are folded up, they form a double-layered, more insulated, enclosed second-floor compartment.

4. The foldable and refoldable double-layer dual-switch RV second-level cabin operating system according to claims 1 and 2, characterized in that: The folding panels are hinged to the lifting roof, allowing them to be folded up or unfolded. The double-layer folding panels are made of either a roller blind or a transparent panel. The main frame has an F-shaped structure forming a U-shaped groove, with the roller blind moving along this groove. A hinged connection to the transparent panel is located on the side of the main frame facing inwards towards the RV. When the user unfolds the double-layer folding panels, the motor inside the roller blind is controlled by a processor to retract it. As the roller blind retracts, the transparent panel forms a transparent window on the second floor of the RV, allowing the user to live and relax in a sunroom, unaffected by wind or rain, and enjoy the view. Furthermore, the user can manually push the transparent panel of the folding panels inwards towards the lifting roof, creating a ventilated terrace similar to a window on the second floor, allowing the user to enjoy the breeze and view the scenery. Finally, the user lowers the roller blind and transparent panel, closing the double-layer folding panels to form a more insulated and enclosed double-layer cabin on the second floor of the RV.

5. The foldable and refoldable double-layer dual-switch operating system for a motorhome's second-floor enclosure, as described in claims 1 and 2, is characterized in that: The double-layer folding panel is made of two materials: an insulating panel and a transparent panel. When the user unfolds the panel, a telescopic push rod controlled by the processor pulls the insulating panel outwards towards the RV's pop-up roof. Once unfolded, it extends horizontally with the roof, forming a sunshade or rain shelter. The transparent panel, as the insulating panel unfolds, becomes a transparent window on the second floor of the RV, allowing the user to live and rest in a room sheltered from wind and rain, and to enjoy the scenery. Furthermore, the user can control the telescopic push rod or rope to fold the transparent panel inwards towards the pop-up roof, creating a ventilated terrace similar to a window on the second floor, allowing the user to enjoy the breeze and scenery. When the user folds up the panel, the insulating and transparent panels close to form a double-layered structure, creating a more insulated and enclosed double-layered cabin on the second floor of the RV.
