[0002] A motorhome combines the functions of a house and a vehicle, but its primary attribute is still that of a vehicle. It is a type of mobile vehicle equipped with essential home amenities, including: bedding, stove, refrigerator, cabinets, sofa, dining table and chairs, washing facilities, air conditioning, television, stereo, and other furniture and appliances. It can be divided into areas such as the driving area, living area, bedroom area, bathroom area, and kitchen area. Modular extended motorhomes refer to a type of motorhome that combines modular design concepts with physical space expansion capabilities. They aim to maximize the use of limited interior space through flexible design, while providing greater adaptability and versatility.

[0003] Compared to regular cars, motorhomes mainly offer larger interior space and more comprehensive facilities. However, since the sides and back of a motorhome are fixed, there is limited interaction between the interior and exterior spaces when camping or engaging in activities, thus limiting its expandability.

[0004] Therefore, we propose a modular extended RV to solve the above problems. Utility Model Content

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a modular expandable RV, which solves the problem mentioned in the background art that, due to the fixed design of the sides and back of the RV, the interaction space between the interior and exterior of the RV is limited, and the expansion capability is restricted when camping or engaging in activities.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example like Figure 1-5 As shown, an embodiment of this utility model proposes a modular extended RV, including a modular RV body 1, a functional platform 4 fixedly mounted on the bottom of the modular RV body 1, and two sets of platform grooves 5 spaced apart on the top of the functional platform 4. A sliding bottom rod 3 is slidably connected in the groove of the platform groove 5. In order to improve the stability of the sliding bottom rod 3, a reinforcing top block 7 is fixedly mounted at the top of the end of the groove of the platform groove 5, so that the sliding bottom rod 3 is supported when it slides outward along the groove of the platform groove 5, thereby improving stability. A modular rear cover plate 10 adapted to the rear opening of the modular RV body 1 is fixedly mounted at the end of the sliding bottom rod 3. The two sides of the modular rear cover plate 10 are open. Through the open openings on both sides, the interior of the entire modular RV body 1 forms an interactive space with the outside through the openings, thereby increasing the permeability of the entire RV interior. The sliding bottom rod 3 is set with a maximum sliding distance to prevent slippage. Limiting top holes 8 and limiting slot holes 9 are respectively provided on the top of the sliding bottom rod part 3 and in the groove of the platform slide 5. When the sliding bottom rod part 3 is fully inserted into the groove of the platform slide 5, the limiting top holes 8 and limiting slot holes 9 are aligned vertically. At this time, the limiting top holes 8 and limiting slot holes 9 can be reinforced and combined by bolts. Thus, the rear space of the modular RV body 1 can be closed by using the modular rear cover plate 10, and the contact point between the modular rear cover plate 10 and the opening of the modular RV body 1 adopts the existing sealing structure.

[0019] The top of the modular rear cover 10 is fixed with a sliding top plate 2, so that the sliding top plate 2, the modular rear cover 10 and the sliding bottom rod 3 form a side U-shaped structure. The inner wall of the groove top of the modular RV body 1 is provided with a slide rail, so that the top of the sliding top plate 2 is fixed with a slider that moves along the slide rail. A reinforcing top block 7 with a spacing is also provided on the top of the sliding bottom rod 3. After the sliding bottom rod 3 is unfolded, the bottom pedal 13 can be attached to the top of the sliding bottom rod 3 for bottom support at the interactive position. The bottom pedal 13 has protrusions at both ends that can be inserted into the holes of the bottom rod top groove 6. During assembly, the protrusions are positioned in the holes of the bottom rod top groove 6 so that multiple sets of bottom pedals 13 can be laid horizontally between the sliding bottom rods 3 with a spacing.

[0020] In the aforementioned sliding bottom rod part 3, a bottom rod groove 14 is provided at the bottom of the sliding bottom rod part 3. A support rod 15 is assembled in the bottom rod groove 14, and the support rod 15 is rotatably connected to the inner wall of the groove of the bottom rod groove 14 through a rotating shaft. The rotating shaft allows the support rod 15 to rotate to a vertical position. The groove height of the bottom rod groove 14 is adapted to the diameter of the support rod 15, so that the support rod 15 can be completely hidden in the groove of the bottom rod groove 14, so as not to affect the sliding of the sliding bottom rod part 3.

[0021] The support rod 15 has an internal thread, and the internal thread is screwed to the adjusting screw part 16. A disc insert rod 17 is fixed at the bottom of the adjusting screw part 16. The adjusting screw part 16 can be rotated by operating the disc insert rod 17 to adjust the length. A support disc 18 is inserted into the bottom of the disc insert rod 17. The support disc 18 is pressed against the ground to provide support for the structure above. The top of the support disc 18 is provided with a positioning groove that is compatible with the disc insert rod 17.

[0022] The surface of the modular rear cover 10 is rotatably connected to a closed side cover 11 via a cover rotation shaft 12. An arc-shaped groove is formed at the center of the end of the closed side cover 11 furthest from the cover rotation shaft 12. Screw holes adapted to the arc-shaped groove are formed on the inner wall of the modular RV body 1. When it is necessary to cover the side space, the closed side cover 11 can be rotated to cover the side. The closed side cover 11 is equipped with multiple sets of cover rotation shafts 12 that run vertically through it. Since the length of the closed side cover 11 is greater than the width of the interactive space, the arc-shaped groove at the front end of the closed side cover 11 will fit against the screw holes inside the modular RV body 1. The closed side cover 11 can then be secured to the inner wall of the modular RV body 1 with bolts, effectively extending the rear of the entire RV.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
