Description

Technical Field

[0001] This utility model relates to the field of RV technology, and in particular to an RV lift-up folding railing and an RV. Background Technology

[0002] A motorhome, combining the functions of a "house" and a "vehicle," is a type of mobile vehicle equipped with essential home amenities. These amenities include bedding, a stove, refrigerator, cabinets, sofa, dining table and chairs, washing facilities, air conditioning, television, and audio equipment. The vehicle can be divided into driving, living, bedroom, bathroom, and kitchen areas. A motorhome integrates "clothing, food, shelter, and transportation," realizing a fashionable product that allows for "living while traveling and traveling while living." With the increasing popularity of motorhomes and the improvement of users' living standards, the requirements for motorhomes are also increasing. They demand both ample living space and ease of driving in various road conditions. To meet diverse user needs, the width and height of motorhomes have been developed to be expandable; for example, the height can be adjusted according to usage requirements. In existing technology, motorhome height expansion is generally achieved by connecting the roof panel to the vehicle roof with a flexible, pleated material such as rubber, or by using a folding panel, allowing for adjustment of the distance between the roof panel and the vehicle roof, i.e., adjusting the motorhome height. However, the soft, pleated material is prone to dust accumulation and aging and deformation after prolonged use, resulting in low space utilization of the folding panel. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide a motorhome with a liftable folding platform and motorhome, which solves the technical problems of the existing motorhome height space expansion structure being relatively complex and prone to aging and deformation after long-term use. It has better flexibility of use, higher space utilization, and adjustable height of the expanded space.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A RV lift-up folding railing is used to be installed on the top of an RV. The RV lift-up folding railing includes a top plate and multiple layers of inner and outer nested telescopic enclosures. An expansion space is formed between the top plate and the enclosures. The top plate is opposite to the top of the RV. The innermost enclosure is fixed to the top of the RV, and the outermost enclosure is fixed to the top plate. As the multiple enclosures extend and retract, the expansion space decreases or increases.

[0006] The RV lifting and stacking railing also includes a drive unit, which is fixed on the RV and drives the top panel to move the top panel up and down, thereby causing the multiple layers of the railing to extend and retract layer by layer.

[0007] As a preferred embodiment of a RV lift-up folding platform, except for the innermost panel, each of the remaining panels extends inward from the end opposite to the top panel to form a first overlapping edge. Except for the outermost panel, each of the remaining panels extends outward from the end near the top panel to form a second overlapping edge. As the top panel moves upward, in every two adjacent panels, the first overlapping edge on the outer panel contacts and lifts the second overlapping edge on the inner panel.

[0008] As a preferred embodiment of a motorhome with a liftable folding railing, the first overlapping edge and / or the second overlapping edge is an annular plate perpendicular to the railing.

[0009] As a preferred embodiment of a RV lift-up folding platform, both the first overlapping edge and the second overlapping edge are provided with anti-slip teeth, and the anti-slip teeth on the first overlapping edge and the anti-slip teeth on the second overlapping edge can mesh.

[0010] As a preferred embodiment of a motorhome with a liftable folding platform, the drive unit includes an electric cylinder, one end of which is hinged to the motorhome and the other end is hinged to the top plate.

[0011] As a preferred embodiment of a motorhome with a liftable and stackable enclosure, a sliding assembly is provided between each pair of adjacent enclosure panels, and each pair of adjacent enclosure panels is slidably connected by the sliding assembly.

[0012] As a preferred embodiment of a RV lift-up folding platform, the sliding assembly includes a slide rail and a slider. In each pair of adjacent enclosures, the slide rail is laid on the inner side of the outer enclosure, and the slider is fixed on the outer side of the inner enclosure. The slider is slidably connected to the slide rail.

[0013] As a preferred embodiment of a RV lift-up folding platform, the slider is located near the end of the enclosure panel close to the top panel.

[0014] As a preferred embodiment of a RV lift-up railing, the slider is detachably mounted on the enclosure panel.

[0015] A motorhome, comprising the motorhome lift-up folding railing described in any of the above technical solutions.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model provides a RV lift-up folding platform. By driving the top plate upwards with a drive mechanism, the nested multi-layered panels extend layer by layer, increasing the interior space and effectively expanding the RV's interior space to meet user needs. Conversely, by driving the top plate downwards with the drive mechanism, the nested multi-layered panels retract layer by layer, reducing the interior space and thus lowering the overall height of the RV to facilitate passage through height-restricted areas. During the layer-by-layer extension and retraction, the expanded space can be adjusted and controlled, for example, only extending or retracting a portion of the panels. Furthermore, the multi-layered panels only extend and retract in the height direction, resulting in high space utilization. Compared to the folding rubber material expansion structures used in existing technologies, this RV lift-up folding platform structure is simple, rigid, and less prone to aging, deformation, and dust accumulation over long-term use. It is also easy to operate, offers better flexibility, and can meet diverse user needs.

[0018] This embodiment also provides a motorhome that, by adopting the above-mentioned motorhome lift-and-fold railing, can meet the diverse needs of customers. It can satisfy the need for large space use, as well as the need for driving on roads with height restrictions. Moreover, it has a simple structure and good appearance and neatness.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0037] like Figures 1 to 11As shown, this embodiment provides a RV lift-up folding railing, which is used to be installed on the RV roof 10. The RV lift-up folding railing includes a roof panel 1 and multiple layers of inner and outer nested telescopic enclosure panels 2, forming an expansion space between the roof panel 1 and the enclosure panels 2. The roof panel 1 is opposite to the RV roof 10. The innermost enclosure panel 21 is fixed to the RV roof 10, and the outermost enclosure panel 21 is fixed to the roof panel 1. As the multiple enclosure panels 21 extend and retract, the expansion space decreases or increases. The RV lift-up folding railing also includes a drive component 3, which is fixed on the RV and drives the roof panel 1 to move the roof panel 1 up and down, thereby causing the multiple enclosure panels 21 to extend and retract layer by layer. By driving the top plate 1 upward with the drive component 3, the nested multi-layered enclosure panels 21 can be extended layer by layer to increase the expanded space, effectively increasing the interior space of the RV, such as expanding the height space of the front bed to meet user needs. Conversely, by driving the top plate 1 downward with the drive component 3, the nested multi-layered enclosure panels 21 can be retracted layer by layer to reduce the expanded space, thereby lowering the overall height of the RV to facilitate passage through height-restricted areas. The layer-by-layer extension and retraction of the multi-layered enclosure panels 21, i.e., the up-and-down movement of the top plate 1 driven by the drive component 3, causes each layer of enclosure panel 21 to rise and fall sequentially, which helps save power, improves space utilization, and enhances the overall structural compactness. During layer-by-layer extension and retraction, the expanded space can be adjusted and controlled, for example, only extending or retracting a portion of the enclosure panels 21. Furthermore, the multi-layered enclosure panels 21 only extend and retract in the height direction, resulting in high space utilization. Compared to the folding rubber material extension structure used in existing technologies, this RV's lifting and stacking structure is simple, is a rigid structure, is not prone to aging or deformation after long-term use, is not prone to dust accumulation, has a better appearance and neatness, is easy to operate, has better flexibility of use, and can meet different user needs.

[0038] It should be noted that the shape of the RV's lift-up folding platform is not limited here. It can be designed according to the shape of the RV's roof or the user's needs. For example, the shape of the RV's lift-up folding platform can be rectangular, pentagonal, hexagonal, or irregular.

[0039] Among them, the enclosure 21 can be two, three, four or five layers, etc., depending on the actual needs.

[0040] Specifically, such as Figures 7 to 11 As shown, the driving component 3 includes an electric cylinder. One end of the electric cylinder is hinged to the RV, and the other end is hinged to the roof panel 1. Specifically, the free end of the telescopic rod of the electric cylinder is hinged to the roof panel 1. By extending and retracting the telescopic rod of the electric cylinder, the roof panel 1 can be moved up and down. The structure is simple and reliable, the driving is convenient, and the stability is good.

[0041] More specifically, a hinge seat 4 is provided on the side of the roof panel 1 facing the roof 10 of the RV, and one end of the electric cylinder is hinged to the hinge seat 4 via a hinge shaft. The connection between the electric cylinder and the roof panel 1 is achieved through the hinge seat 4, which has high reliability and stability. Furthermore, the hinge between the electric cylinder and the roof panel 1 allows the axial direction of the electric cylinder to have a certain angle with the normal direction of the roof panel 1, which facilitates the arrangement of the electric cylinder and improves space utilization.

[0042] In this embodiment, the drive component 3 can be selected, but is not limited to, one. For example, there can be two, three, or four drive components 3, as long as the reliability and stability of the RV's lifting and stacking railings are ensured.

[0043] In one embodiment, such as Figures 6 to 9 As shown, except for the innermost panel 21, each of the other panels 21 extends inward from the end opposite to the top plate 1 to form a first overlapping edge 22. Except for the outermost panel 21, each of the other panels 21 extends outward from the end near the top plate 1 to form a second overlapping edge 23. As the top plate 1 moves upward, in every two adjacent panels 21, the first overlapping edge 22 on the outer panel 21 contacts and lifts the second overlapping edge 23 on the inner panel 21. The driving component 3 provides the driving force. When the top plate 1 moves upward, it drives the outermost enclosure 21 to move upward until the first overlapping edge 22 on the enclosure 21 contacts the second overlapping edge 23 on the adjacent inner enclosure 21. As the top plate 1 continues to move upward, each enclosure 21 moves upward sequentially from the outside to the inside, achieving the extension of all enclosures 21. This ensures the continuous unfolding of the multiple enclosures 21 and prevents them from falling off. When the top plate 1 moves downward, under the action of gravity, the second inner enclosure 21... The first overlapping edge 22 moves down away from the second overlapping edge 23 on the innermost panel 21. The top panel 1 and all other panels 21 except the innermost panel 21 move down synchronously until the lower end of the second innermost panel 21 touches the bottom, for example, supported on the RV roof 10 or supported on the limiting support plate set at the bottom of the innermost panel 21, so as to avoid the first overlapping edge 22 of the second innermost panel getting stuck at the lower end of the innermost panel 21 and causing interference. The other panels 21 are similar. Then, the multiple panels 21 are folded up layer by layer from the inside to the outside.

[0044] Understandably, under the above structure, by controlling the extension and retraction length of the drive end of the drive component 3, the vertical movement distance of the top plate 1 can be realized, thus controlling the size of the expanded space and achieving stepless height adjustment to adapt to different usage needs, providing excellent flexibility. For example, only two or half of the enclosure panels 21 can be unfolded or retracted.

[0045] Preferably, the first overlapping edge 22 and / or the second overlapping edge 23 are annular plates perpendicular to the surrounding plate 21, which have better uniform force distribution and load-bearing capacity, and greater space utilization. Of course, in other embodiments, the first overlapping edge 22 and / or the second overlapping edge 23 may also be set at an angle to the surrounding plate 21, such as 60° or 80°, etc., which is not limited here.

[0046] More preferably, anti-slip teeth 24 are provided on both the first overlapping edge 22 and the second overlapping edge 23. The anti-slip teeth 24 on the first overlapping edge 22 engage with the anti-slip teeth 24 on the corresponding second overlapping edge 23, further increasing the stability between the connected panels 21.

[0047] In another embodiment, such as Figure 10 and Figure 11 As shown, a sliding component 5 is provided between every two adjacent enclosure panels 21, and the two adjacent enclosure panels 21 are slidably connected by the sliding component 5. The setting of the sliding component 5 not only realizes the connection between every two adjacent enclosure panels 21, but also makes the connection friction between the enclosure panels 21 small, which is beneficial to improving the smoothness of movement and saving power.

[0048] Specifically, the sliding component 5 includes a slide rail 51 and a slider 52. In each pair of adjacent enclosures 21, the inner side of the outer enclosure 21 is provided with the slide rail 51, and the outer side of the inner enclosure 21 is fixed with the slider 52, which is slidably connected to the slide rail 51. When the driving member 3 drives the top plate 1 to move upward, it causes the outermost enclosure 21 to slide upward relative to the second outer enclosure 21 via the slide rail 51 and the slider 52, and so on, causing each layer of enclosures 21 to slide upward in sequence. When the driving member 3 drives the top plate 1 to move downward, the second inner enclosure 21 slides down under the action of gravity, and each layer of enclosures 21 slides down in sequence. The stability of each layer of enclosures 21 during up and down sliding is good, and it is not easy to slip, shift position, or jam, and it can effectively save power. Of course, in other embodiments, the sliding component 5 can also be other structures, such as a sliding rod and a sliding sleeve.

[0049] The slider 52 is positioned near the end of the surrounding plate 21 closest to the top plate 1, for example, one end of the slider 52 is flush with the end of the surrounding plate 21 closest to the top plate 1. This ensures that the extended space of the surrounding plate 21 is sufficiently large, improving space utilization and avoiding wasted space.

[0050] Preferably, the slider 52 is detachably mounted on the enclosure 21, for example, by bolts, which facilitates the replacement of the slider 52 and saves maintenance costs.

[0051] In this embodiment, limit baffles are provided at both ends of the slide rail 51 to prevent the slider 52 from disengaging from the slide rail 51, thus ensuring the reliability of the multi-layer enclosure 21. Preferably, the limit baffles are detachably connected to the slide rail 51 for easy replacement or disassembly of the slider 52.

[0052] This embodiment also provides a motorhome, which includes the aforementioned motorhome lift-up folding platform. By equipping the motorhome with the motorhome lift-up folding platform, the top space of the motorhome can be expanded and the top height can be reduced, so as to meet the user's needs for large space and driving needs. It has better flexibility of use, and the structure is simple, the space utilization rate is high, and the operation is easy.

[0053] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention.
