Abstract
Description
Technical Field
[0001] This utility model relates to the field of RV technology, specifically to an expandable cabin and an expandable RV. Background Technology
[0002] This section introduces background technology that may be related to various aspects of the embodiments of this utility model, which is believed to provide useful background information to help readers better understand the various aspects of the embodiments of this utility model. Therefore, it is understood that the description in this section is for the above purposes and does not constitute an admission of the prior art.
[0003] With the rapid development of society and the economy, people's living standards are constantly improving, and more and more people enjoy self-driving tours. Motorhomes, due to their convenience and comfort, have become the first choice for self-driving tours. A motorhome, also known as a "home on wheels," combines the functions of a "house" and a "vehicle," but its primary attribute is still a vehicle—a mobile vehicle with essential home-like facilities. Due to height and width restrictions on motorhome operation, their size is limited. Motorhomes are generally fixed, and their overall size limitation results in a smaller interior space, typically only able to accommodate a single bed with a narrow width, offering limited comfort.
[0004] To maximize living space and enhance travel comfort, a common approach is to utilize other interior structures to create additional sleeping areas. However, this often prevents the simultaneous use of other spaces and structures. In recent years, one solution for expanding RV living space has been the installation of side extensions. Without altering the overall length of the RV, one or more extensions are frequently installed, significantly increasing interior space. These extensions extend to the left, right, or rear via a drive mechanism. However, directly extending the side extension with its cantilevered arm is limited by gravity, resulting in a smaller living space. Further outward extension requires consideration of support. One approach is to install guide rails along the RV's floor beams, with support columns at the far ends. However, this structure is complex and requires consideration of ground flatness, stability, and load-bearing capacity. Therefore, increasing sleeping space without compromising other interior structures and usability remains a critical challenge. Utility Model Content

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0052] like Figures 1 to 12 As shown, this utility model embodiment provides an expandable room, including: a body 1, the body having multiple side walls 11, each side wall 11 including a top wall, a bottom plate, a left wall, a right wall, and a rear wall; at least one of the side walls 11 is provided with an expansion window 110, and a folding expansion compartment 2 is installed on the expansion window 110; a bed board 3 is provided inside the folding expansion compartment 2 within the body 1; a folding bed board 32 corresponding to and matching the bed board 3 is provided inside the folding expansion compartment 2; the folding expansion compartment 2 expands outward, so that the folding bed board 32, after unfolding, is flush with the bed board 3, expanding the area of the bed board 3. The following is a detailed description of the expansion of the expandable room provided by this utility model embodiment.
[0053] like Figures 3 to 11 As shown, in this embodiment of the present invention, the folding expandable compartment 2 includes an expandable wall 21 and an expandable protective wall 22; after the folding expandable compartment 2 is folded into the compartment body, the expandable wall 21 covers and seals the expandable window 110; after the folding expandable compartment 2 is unfolded, the expandable protective wall 22 fills the gaps between the two sides of the expandable wall 21 and the expandable window 110. Figures 3 to 11As shown in this embodiment of the utility model, in order to ensure the flatness of the interior of the compartment 1 and improve the visual aesthetics, expansion gaps 120 are provided on both sides of the expansion window 110. After the folding expansion compartment 2 is folded into the compartment 1, the expansion protective wall 22 enters the expansion gap 120, and the folded expansion protective wall 22 is not visible inside the compartment 1. Figures 2 to 5 As shown, in this embodiment of the present invention, a drainage pipe 100 is provided inside the expansion window 110. When rainwater enters the expansion window 110, the rainwater gathers at the bottom and is discharged to the top of the drainage pipe 100, thus preventing the rainwater from entering the interior of the compartment 1.
[0054] like Figures 6 to 12 As shown in this embodiment of the invention, the bottom of the expansion wall 21 is provided with a lower waterproof baffle 211, and the lower edge of the expansion window 110 is provided with a lower baffle 111 extending inward into the expansion window 110. After the folding expansion compartment 2 is folded into the compartment 1, the lower waterproof baffle 211 is parallel to the outer side of the lower baffle 111. The lower waterproof baffle 211 partially overlaps with the outer side of the lower baffle 111. This makes it difficult for rainwater left from the top after the folding expansion compartment 2 is folded to enter the expansion window 110. Further, the folding expansion compartment 2 also includes a bottom plate 210, the edge of which is provided with an expansion baffle 212 extending towards the bottom of the compartment 1. After the folding expansion compartment 2 is unfolded, the expansion baffle 212 is parallel to the inner side of the lower baffle 111. The expansion baffle 212 is partially parallel to the lower baffle 111. This makes it difficult for rainwater left from the top after the folding expansion compartment 2 is unfolded to enter the expansion window 110. Furthermore, sealing structures are provided on both sides of the lower baffle 111. After the folding expansion compartment 2 is folded into the compartment 1, the sealing structure is sandwiched between the lower waterproof baffle 211 and the outer side of the lower baffle 111, ensuring that the folding expansion compartment 2 is not prone to air leakage after folding. After the folding expansion compartment 2 is unfolded, the sealing structure is sandwiched between the expansion baffle 212 and the inner side of the lower baffle 111, ensuring that the folding expansion compartment 2 is not prone to air leakage after unfolding. To further enhance the overall integrity of the product, a storage space 30 is provided below the bed board 3. After the folding expansion compartment 2 is folded into the compartment 1, the bottom plate 210 is stored in the storage space 30.
[0055] like Figures 6 to 12As shown in this embodiment of the invention, the bottom of the expansion wall is provided with an upper waterproof baffle 222, and the upper edge of the expansion window 110 is provided with an upper baffle 112 extending inward from the expansion window 110. After the folding expansion compartment 2 is folded into the compartment 1, the upper waterproof baffle 222 is parallel to the outer side of the upper baffle 112. Sealing structures are provided on both sides of the upper baffle 112; after the folding expansion compartment 2 is folded into the compartment 1, the sealing structures are sandwiched between the upper waterproof baffle 222 and the outer side of the upper baffle 112. Therefore, the folding expansion compartment 2 is less prone to air and water leakage after folding.
[0056] like Figures 1 to 12 As shown in this embodiment of the utility model, in order to further reduce the structural difficulty, the top of the folding expansion compartment 2 rotates along the top of the expansion window 110, so that the folding expansion compartment 2 is folded into the compartment 1 or the folding expansion compartment 2 is unfolded.
[0057] In this embodiment of the present invention, to further demonstrate the advanced nature of the expandable cabin provided by the present invention, this embodiment of the present invention also provides an expandable RV, including a vehicle body and a cabin fixed on the vehicle body, wherein the cabin is the aforementioned expandable cabin.
[0058] In summary, the expandable cabin and expandable RV provided by this utility model embodiment, by installing a folding expandable cabin on the expandable window and utilizing the folding bed board set inside the folding expandable cabin, the area of the folding expandable cabin after it expands outward and is flush with the area of the folding bed board after it is unfolded can be easily folded and stored without affecting the space inside the cabin or interfering with other items inside the cabin. It has the advantages of simple and convenient operation for storage and unfolding.
