Abstract
Description
Technical Field
[0001] This utility model relates to the field of RV technology, specifically to a pop-top extendable RV door structure, extendable compartment, and extendable 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 the demand for RVs is increasing. RVs, also known as "homes on wheels," combine the functions of a "house" and a "vehicle," but their primary attribute is still that of a vehicle—a mobile vehicle equipped with essential home amenities. Due to height and width restrictions on RV travel, their size is limited, and they are generally fixed, with limited interior space and comfort. To further enhance travel comfort, people use extension structures to expand the interior space of RVs. These extension structures are deployed at RV campsites or parking lots to increase space and improve interior utilization. Existing extension structures are all horizontal, limiting the expansion space and area.
[0004] Larger living spaces offer greater comfort, but traditional RVs are bulky. To increase usable space, some existing RVs feature a pop-up roof on top of the cabin. When not in use, the pop-up roof lowers the center of gravity and improves safety while the RV is in motion. The roof is a rigid, flat structure designed to protect the upper part of the vehicle. This increases the interior height, allowing people to stand comfortably inside. Current RVs only have a fixed door on one side. Because the lower level is occupied by the chassis and the upper level also takes up height, the height of the fixed door is limited by the height of the lower level cabin and interfered with by the lifting mechanism of the upper level cabin. This means passengers have to duck to get in and out, avoiding bumping their heads against the door frame, making it extremely inconvenient. Existing motorhomes are designed in two sections, often requiring the upper section to be raised before the door can be opened and closed again, which is unacceptable. Furthermore, adjusting the height makes opening and closing the door inconvenient. Additionally, the inability to create a closed space hinders sound insulation and noise reduction, and air leaks are common, failing to minimize the impact of the environment on the extended compartment and posing significant safety hazards. Summary of the Invention
[0005] The problem to be solved by this utility model embodiment is how to provide a door structure, an expandable room, and an expandable RV for a pop-up expandable RV.
[0006] To address the shortcomings of existing technologies, this utility model provides a pop-up extendable RV door structure, extendable compartment, and extendable RV, which can effectively avoid noise during the raising and lowering of the upper compartment.
[0007] In a first aspect, this utility model embodiment provides a door structure for a pop-up expandable RV, which is installed on a compartment where a lower compartment is fitted onto an upper compartment. The door structure includes:
[0008] A door frame, on which a door leaf is connected, and the door frame is fixed to the lower housing;

[0053] 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.
[0054] like Figures 1 to 10As shown in the figure, this utility model provides a pop-up expandable RV door structure, which is installed on the lower compartment 1 and the upper compartment 2. The door structure 3 includes: a door frame 30, on which a door leaf 31 is connected, and the door frame 30 is fixed to the lower compartment 1; the upper compartment 2 is provided with a door frame window 20 that nests and matches the door frame 30, so that when the upper compartment 2 is lowered, the door frame 30 on the lower compartment 1 is embedded in the door frame window 20. A door frame positioning mechanism 4 is provided between the door frame 30 and the door frame window 20; the door frame positioning mechanism 4 includes: positioning slide rails 40 provided on both sides of the outer side of the door frame 30 and positioning protrusions 41 provided on the inner side of the door frame window 20; the positioning slide rails 40 and the positioning protrusions 41 are matched. The pop-up expandable RV provided by this utility model embodiment will be described in detail below.
[0055] In the embodiments of this utility model, such as Figures 4-10 As shown, the door frame positioning mechanism includes: a positioning slide rail 40 disposed outside the door frame and a protrusion 41 disposed inside the door frame window; the positioning slide rail 40 matches the positioning protrusion 41. After the upper compartment 2 descends, the door frame 10 disposed on the lower compartment 1 is embedded in the door frame window 20. At the same time, the positioning slide rail 40 is also inserted into the positioning protrusion 41, and the door frame 10 disposed on the lower compartment 1 fits tightly with the upper compartment 2, making it more stable. The door frame positioning mechanism disposed between the door frame 30 and the door frame window effectively ensures the stability of the upper compartment 2 after it descends, and further ensures the stability of the door structure 3 on the lower compartment 1. During the lifting and lowering of the upper compartment, the positioning protrusion 41 slides within the positioning slide rail 40. The contact area between the positioning protrusion 41 and the positioning slide rail 40 is small, effectively avoiding noise during the lifting and lowering of the upper compartment. It is understandable that the positioning protrusion 41 and the positioning slide rail 40 can be interchanged. For example, the door frame positioning mechanism 4 includes a positioning protrusion 41 disposed outside the door frame 20 and positioning slide rails 40 disposed on both sides inside the door frame window 20.
[0056] In the embodiments of this utility model, such as Figures 6-9 As shown, to facilitate the lowering of the upper compartment 2 onto the lower compartment 1, the positioning slide rails 40 on both sides of the door frame 30 and the positioning protrusions 41 on the inside of the door frame window 20 can achieve precise alignment. The end of the protrusion 41 is tapered. The end of the positioning slide rail 40 is provided with an alignment ramp.
[0057] Compared with the prior art, in this embodiment of the utility model, Figure 4 and Figure 5 As shown, in order to reduce the area of the door frame window 20, the area of the door frame 30 needs to be as small as possible, and the top of the door frame 30 should not be higher than the top of the lower compartment 1.
[0058] In the embodiments of this utility model, such as Figures 3-5 As shown, to prevent the door frame window 20 from being exposed and causing safety hazards after the upper compartment 2 is raised, a folding door frame window cover 25 is provided on the inside of the door frame window 20 to cover it. The folding door frame window cover 25 can be an electrically folding cover. When the upper compartment 2 is raised, the folding door frame window cover 25 is raised to cover the door frame window 20, so that the upper compartment 2 forms a closed space.
[0059] In the embodiments of this utility model, such as Figures 11A to 11B As shown, the folding door frame window cover 25 can fold inwards or outwards from the upper compartment 2 as needed. The folding door frame window cover 25 can be formed from two or more single panels connected end-to-end. For example, one end of the folding door frame window cover 25 is fixed to the upper compartment 2, and the other end is fixed to the lower compartment 1. The folding door frame window cover 25 unfolds as the upper compartment 2 is raised, covering and sealing the door frame window 20. Both ends of the folding door frame window cover 25 can be connected to the upper compartment 2 or the lower compartment 1 respectively via hinges, and the single panels can be combined using a flexible connecting mechanism to form the folding door frame window cover 25. Figures 12A to 12D As shown, the folding door frame window cover 25 can be formed by two or more single panels connected end to end, or it can be unfolded by rotating the single panels to cover and close the door frame window 20. The folding door frame window cover 25 can unfold automatically when the upper compartment 2 is lifted, or it can be unfolded manually after the upper compartment 2 is lifted into place. The folding door frame window cover 25 can also be extended with the assistance of an electric extension device. Furthermore, in order to effectively prevent rainwater from leaking into the upper compartment 2 and the lower compartment 1 at the joint between the folding door frame window cover 25 and the door frame window 20 on rainy days, a sealing gasket is provided on the edge of the folding door frame window cover 25. After the upper compartment 2 is lifted, the folding door frame window cover 25 covers and closes the door frame window 20, and the sealing gasket further seals the gaps. In order to further improve the sealing and safety, the folding door frame window cover 25 can be locked to close the door frame window 20 by a locking mechanism.
[0060] To further demonstrate the advanced features of the pop-up expandable cabin provided by this invention, this utility model embodiment also provides an expandable RV, such as... Figures 1 to 5 As shown, the pop-up expandable cabin includes a lower cabin 1 and an upper cabin 2 fitted onto the lower cabin 1, and the cabin is equipped with the aforementioned vehicle door structure.
[0061] To further demonstrate the advanced features of the pop-up expandable cabin provided by this invention, this utility model embodiment also provides an expandable RV, such as... Figure 13 As shown, the extended RV includes a vehicle body 8 and a room fixed to the vehicle body 8; the room is the aforementioned pop-up extended room.
[0062] In summary, this utility model provides a pop-up expandable RV door structure, expandable compartment, and expandable RV. By setting a door frame higher than the lower compartment on the lower compartment and a matching door frame window on the upper compartment, the lower compartment's door frame window is embedded in the upper compartment when the upper compartment is lowered. This eliminates the door height limitation caused by the lower compartment's height, and height adjustment does not interfere with door opening and closing. A door frame positioning mechanism between the door frame and the door frame window ensures the stability of the lower compartment door while effectively preventing noise during the raising and lowering of the upper compartment. When the upper compartment is raised, a folding door frame window cover can be raised to conceal the door frame window, creating a closed space within the upper compartment, effectively achieving sound insulation and heat preservation, and effectively preventing environmental impact on the use of the expandable compartment.
