Description

Technical Field

[0001] The invention relates to a lifting and folding roof structure and a folding and unfolding control system, and belongs to the field of production and manufacturing of a folding and lifting roof of a motorhome and a folding motorhome. Background Art

[0002] With the improvement of living standards, more and more people spend their leisure time traveling by car and camping outdoors. In order to improve the quality of traveling by car and camping outdoors, meet the needs of travel, and get a better experience, RVs are a good choice. However, the existing RV space is limited. In order to expand the RV space, the existing RV expansion body or lifting ceiling technology uses a lifting bracket to support the ceiling to make a terrace or sun viewing platform, which cannot flexibly form a closed body, and cannot be used for long-term living and rest in the lifting ceiling area, resulting in low RV space utilization; another method uses a lifting bracket to support the ceiling and directly connect the retractable curtain or ceiling board to form a closed space, which has a complex structure and an unsightly appearance, and cannot be flexibly transformed from a closed space to an open terrace or sun viewing platform; with the rise of energy-saving new energy electric RVs, a layer of solar panels is installed on the roof of the existing RV or a part of the solar panels are extended and pulled out, which increases the thickness of the RV roof, occupies the standard RV box living space, and reduces the RV utilization rate. Summary of the invention

[0003] The present invention provides a control system for a RV lifting and folding roof structure, the purpose of which is to provide a RV compartment space that is closed when unfolded, a terrace or a sun viewing platform when folded and combined, and after being lowered, it is combined with the RV to form a standard RV appearance size, with a reasonable structure, convenient operation, beautiful appearance, increased RV living space, and improved RV life quality; and by arranging solar panels on the folding roof panels or fence panels of the two-story RV compartment in the present invention, the solar panels can be folded, stowed, and unfolded to generate electricity, thereby increasing the area of ​​the RV solar panels and maximizing solar power generation; further, ventilation windows are arranged on the folding roof panels or fence panels to expand to increase the area of ​​the solar panels, and the windows are retracted to close, and are integrated with the folding roof panels or fence panels to form a RV box space; it is convenient to operate, has a reasonable structure, increases the standard RV box living space, and increases the utilization rate of the RV.

[0004] The present invention is implemented as follows: the lifting and folding roof of the RV compartment includes a hinged connection in which a lifting roof panel and a stackable folding roof panel are stacked together, and the folding roof panel is pushed to unfold and fold by an electric telescopic mechanism; when a user parks the RV, an instruction to open or close the lifting and folding roof is sent by the user end and transmitted to a processor through a communication network device or circuit, and an application is preset in the processor to control the electric lifting mechanism or the electric telescopic mechanism to push the folding roof panel to fold or unfold, and to push the lifting and folding roof to rise or fall; the folding roof panel and the lifting roof panel are connected by an axial rotation, and the folding roof panel can be folded or unfolded; the unfolded folding roof panel and the lifting roof panel form a second-layer compartment space on the upper part of the fixed ceiling of the RV compartment, forming an upper and lower compartment of the RV.

[0005] The lifting and folding roof comprises a hinge connection of a lifting roof panel and a stackable folding roof panel, which are controlled to be lifted or lowered by a lifting bracket, and the folding roof panel and the lifting roof panel are connected to each other by an axial rotation, and the folding roof panel can be folded or unfolded; the unfolded folding roof panel and the lifting roof panel form a second-layer compartment space on the upper part of the fixed ceiling of the RV compartment, forming the upper and lower compartments of the RV; the folding roof panel is folded to form an upper terrace or a sun viewing platform of the RV.

[0006] When the user terminal sends an instruction to open the liftable folding roof, the preset application in the processor starts the electric lifting mechanism, controls the lifting bracket to prop up the liftable folding roof and fully raise it, and further, the preset application in the processor starts the electric telescopic mechanism of the liftable folding roof to push the folding roof panel to unfold. The electric telescopic mechanism is divided into an inner electric telescopic mechanism and an outer electric telescopic mechanism. The preset application of the processor first turns on the outer electric telescopic mechanism to push the folding roof panel folded on the outside to unfold. After the outer folding roof panel is unfolded, the inner folding roof panel is exposed. The preset application of the processor controls the inner electric telescopic mechanism to push the inner folding roof panel to unfold. The unfolded inner and outer folding roof panels are unfolded according to the four sides of the fixed ceiling of the RV compartment to form the second layer of the RV compartment space.

[0007] The user end sends a command to close the lifting and folding roof and transmits it to the processor. The preset application in the processor controls the inner electric telescopic mechanism to first pull back the inner folding roof panel for folding and overlapping. After overlapping, the preset application in the processor further controls the outer electric telescopic mechanism to pull back the outer folding roof panel for folding and overlapping. The inner and outer folding roof panels are overlapped with the lifting roof panels to form a lifting and folding roof. Further, the preset application in the processor controls the lifting mechanism to retract the lifting bracket and descend, thereby driving the lifting and folding roof to descend and overlap with the fixed roof of the RV compartment to form the standard outer dimensions of the RV compartment.

[0008] The lifting bracket supports the lifting folding roof to rise, and the unfolded folding roof plate is the second-layer car body structure above the fixed roof of the RV car body, forming a two-layer RV car body with upper and lower layers.

[0009] As an optional embodiment, the folding ceiling panel or fence panel is made of translucent or opaque material, and a viewing window, ventilation window or lighting facility is arranged on it. The material is translucent glass, sun panel or opaque insulation panel, solar panel. Translucent or opaque material is selected as needed, and one or more roller blinds are arranged as needed to block wind, rain and mosquitoes. BRIEF DESCRIPTION OF THE DRAWINGS
