Description

Technical Field

[0001] The utility model relates to the technical field of RVs, and in particular to a sealing structure for an expanded RV, an expanded compartment and an expanded RV. Background Art

[0002] This section introduces the background technology that may be related to various aspects of the embodiments of the present utility model to the readers, and is believed to provide the readers with useful background information, thereby helping the readers to better understand various aspects of the embodiments of the present utility model. Therefore, it can be understood that the description in this section is used for the above purpose and does not constitute an admission of the prior art.

[0003] With the rapid development of social economy, people's living standards are constantly improving, and the demand for RVs is getting higher and higher. RVs, also known as "homes on wheels", have both "houses" and "cars", but their attributes are still cars. They are a type of mobile car with basic facilities necessary for home. Due to the height and width restrictions on RV driving, the size of RVs is limited. RVs are generally fixed, with limited internal space and low comfort. In order to further increase the comfort of travel, people use expansion structures to expand the internal space of RVs. The expansion structure is expanded in RV camps or parking lots to increase the space, which can provide passengers with spacious sleeping and activity space and improve the internal utilization rate. Some of the existing expansion structures are expanded in the horizontal direction, with limited expansion space and limited expansion area. In order to increase the usable space of RVs, some existing RVs will be equipped with a lifting roof on the upper end of the RV compartment. When not in use, the lifting roof is set on the upper end of the RV compartment, so that the center of gravity can be lowered during the driving of the RV and safety can be improved.

[0004] Whether it is expanding horizontally or vertically, the car body itself and the expansion box are two separate independent parts, which leads to gaps in the joints. Rainwater, dust, cold wind, noise, etc. enter through the gaps. At the least, it affects the user's experience and satisfaction with the product. At the worst, dust, gravel, and water vapor enter the interior and cause problems such as damage or rust of parts, posing a safety hazard to the driving safety of the RV. In addition, the outside of the expansion box may be stained with water droplets and debris due to the temperature difference between day and night or weather reasons. These things will be collected into the car together during the retraction of the expansion box. At present, in order to solve such problems, it can only be solved by filling sealant in limited gaps or using a single-layer sealing strip. However, sealant is not suitable for the movable parts that need to be extended and retracted around the expansion box, and the single-layer sealing strip cannot meet the required sealing requirements. The existing sealing method has very large friction noise during the extension or retraction of the expansion box, so the existing two methods cannot solve the sealing problem of the expansion box well.

[0041] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] like Figures 1 to 3 As shown, the sealing structure for an expansion RV provided by the embodiment of the utility model includes a sealing body 6, which is arranged between the first compartment 1 and the second compartment 2 which are mutually nested; the sealing body 6 is along the inner wall 11 of the first compartment 1 and / or the outer wall 22 of the second compartment 2; the sealing body 6 is a hollow structure, and the sealing body 6 is also connected to a control mechanism 8 that can be filled with a medium; the control mechanism 8 is used to fill the sealing body 6 with a medium to expand the sealing body 6, so that the expanded sealing body 6 fills the gap 5 between the first compartment 1 and the second compartment 2; or, the control mechanism 8 is used to release the pressure of the medium filled in the expanded sealing body 6, so that the expanded sealing body 6 fills the gap 5 between the first compartment 1 and the second compartment 2. The sealing structure for an expansion RV provided by the embodiment of the utility model is described in detail below.

[0043] In the embodiment of the present utility model, Figure 2-Figure 9 As shown, in order to completely seal the gap 5 between the first body 1 and the second body 2 which are connected to each other, sealing grooves 10 are provided around the inner wall 11 of the first body 1 and / or the outer wall 22 of the second body 2, and the sealing grooves 10 are connected to each other, and a sealing body 6 is laid in the sealing grooves 10. The opening of the sealing groove 10 faces the outer wall 22 of the second body or the inner wall 11 of the first body. The first body 1 and the second body 2 can be a lifting type expansion compartment structure, or a horizontal horizontal expansion compartment structure.

[0044] In the embodiment of the present utility model, Figure 8-10 As shown, the sealing body 6 is a silicone airbag. The silicone airbag can effectively ensure its flexibility and durability, and prevent aging from affecting the seal. Furthermore, the cross section of the sealing body 6 is rectangular. Since the groove wall and groove bottom of the sealing groove 10 are both made of hard materials, the groove position is vacant, and therefore, the sealing body 6 is not constrained at the groove position. Figure 3 and Figure 9-10 As shown in the figure, the control mechanism 8 is used to fill the sealing body 6 with a medium to expand the sealing body 6, and the sealing body 6 expands outward at the notch position so that the expanded sealing body 6 fills the gap 5 between the first body 1 and the second body 2. Figure 11-12 As shown, further, in order to increase the service life of the sealing body 6, the cross section of the sealing body 6 close to the outer wall 22 of the second compartment 2 or the inner wall 11 of the first compartment 1 is C-shaped. When sealing is required, the control mechanism 8 is used to fill the sealing body 6 with a medium to expand the sealing body 6, such as Figure 3 and Figure 9-10As shown, the sealing body 6 expands outward at the notch position to form a D-shaped structure, so that the expanded sealing body 6 fills the gap 5 between the first compartment 1 and the second compartment 2. Figure 11-12 As shown, when sealing is not required, the control mechanism 8 is used to release the pressure of the medium filled in the expanded sealing body 6, and the sealing body 6 shrinks inward at the notch position to form a C-shaped depression, so that the expanded sealing body 6 shrinks and leaves the gap 5 between the first compartment 1 and the second compartment 2. This can effectively avoid the back and forth friction and damage to the sealing body 6 caused by incomplete pressure relief during the expansion or contraction of the first compartment 1 and the second compartment 2.

[0045] In order to further reflect the advanced nature of the lift-top expansion compartment provided by the present invention, the embodiment of the utility model also provides an expansion RV, such as Figures 1 to 5 As shown, the lifting roof expansion compartment comprises a lower compartment body 1 and an upper compartment body 2 sleeved on the lower compartment body 1, and the above-mentioned sealing structure for expansion RV is installed on the compartment.

[0046] In order to further reflect the advanced nature of the lift-top expansion compartment provided by the present invention, the embodiment of the utility model also provides an expansion RV, such as Fig.13 As shown, the expansion RV includes a vehicle body 8 and a cabin fixed on the vehicle body 8; the cabin is the above-mentioned pop-top expansion cabin.

[0047] In summary, the sealing structure, expansion compartment and expansion RV for the pop-up expansion RV provided by the embodiment of the utility model are provided by setting a sealing body between the first compartment and the second compartment which are mutually nested. The sealing body is also connected to a control mechanism that can discharge a medium; the control mechanism is used to release pressure to the medium filled in the expanded sealing body, so that the expanded sealing body fills and detaches from filling the gap between the first compartment and the second compartment. While the compartment is expanding and contracting, the expanded sealing body is contracted to detach from filling the gap between the first compartment and the second compartment, so as to avoid the first compartment and the second compartment which are mutually nested from rubbing back and forth during the expansion or contraction process, thereby damaging the sealing body. When sealing is required, the control mechanism is used to fill the sealing body with a medium to expand the sealing body, so that the expanded sealing body fills the gap between the first compartment and the second compartment, so that the first compartment and the second compartment form a closed space, effectively achieving sound insulation and heat preservation, and effectively avoiding the influence of the environment on the use of the expansion warehouse.
