Description
Technical Field
[0001] The present invention relates to the field of recreational vehicles, and in particular to a variable-length bed for a recreational vehicle and a variable-length recreational vehicle. Background Art
[0002] As a kind of automobile product, RVs must not only ensure the vehicle's driving function but also provide as many living facilities as possible indoors to meet the walking and living needs of RV users.
[0003] From the perspective of vehicle length, self-propelled RVs with a length of less than 6 meters may use a blue license plate. Compared with yellow-plate vehicles, blue-plate vehicles have more advantages in traffic restrictions and usage fees.
[0004] To balance the length limitations of blue-plated RVs and the need to provide both the right-of-way advantage of blue-plated vehicles and the interior living space of RVs, some RVs now feature expandable designs. These allow the RV to be expanded while parked to create a larger interior space. Currently, sleeping accommodations in RVs are typically provided as fixed beds, folding beds, or airbeds. Fixed beds occupy a significant amount of interior space when the RV is not expanded, reducing the space available for other fixed living amenities. Folding or airbeds can be more complex to operate after the RV is expanded.
[0005] In view of this, the inventor conducted in-depth research on this demand, and thus came up with this case. Summary of the Invention
[0006] In view of the problem that the RV expandable design in the prior art adopts fixed beds, when the RV is not expanded, the fixed beds occupy a large amount of indoor space, reducing the space available for arranging other fixed living facilities. After the RV is expanded, folding beds or inflatable beds are used, which are cumbersome to operate. The present invention provides a variable-length bed for RVs, the length of which can change with the expansion of the vehicle. When the bed is in a shortened state, it can ensure that the length of the vehicle meets the length limit of blue-plate vehicles, while providing more space for arranging living facilities; when the vehicle is expanded, the bed can be extended accordingly, without affecting the use of other living facilities, while providing comfortable sleeping conditions, solving the problem that the current folding beds or inflatable beds need to be manually operated. The specific technical solution is as follows:
[0007] A variable-length bed for a recreational vehicle comprises a fixed bed board and a movable bed board, wherein the fixed bed board is fixedly mounted on a fixed body of the recreational vehicle, the movable bed board is fixedly mounted on an extended body of the recreational vehicle, and the movable bed board is slidably mounted on the fixed bed board;
[0008] A fixed mattress is fixedly provided on the upper surface of a portion of the fixed bed board away from the expanded body, and a first variable mattress is hingedly connected to the side of the fixed mattress close to the expanded body. The other side of the first variable mattress extends to the upper surface of the movable bed board and is hingedly connected to a second variable mattress.
[0009] By adopting the above technical solution, utilizing the sliding design of the fixed bed board and the movable bed board, and through the cooperation between them and the fixed mattress, the first variable mattress and the second variable mattress, when the RV is in the expanded state, the bed can be extended accordingly without affecting the use of other living facilities, while providing comfortable sleeping conditions.
[0010] In the contracted state, the movable bed board is located on the side close to the fixed mattress. At this time, the first variable mattress and the second variable mattress are in a retracted state, that is, the first variable mattress and the second variable mattress are in a folded state, forming a triangular structure between the movable bed board; when expanding the RV, the expansion body drives the movable bed board to move backward. At this time, the second variable mattress also extends backward under the action of gravity, and drives the first variable mattress to extend backward. The angle between the first variable mattress and the second variable mattress gradually increases to 180°. At this time, the RV is in an expanded state.
[0011] Preferably, the fixed mattress is hinged to the first variable mattress via a first hinge shaft, and the first variable mattress is hinged to the second variable mattress via a second hinge shaft;
[0012] The first hinge axis is parallel to the second hinge axis and perpendicular to the sliding direction of the movable bed board.
[0013] Preferably, the plane where the movable bed board is located is parallel to the plane where the fixed bed board is located; and a notch for accommodating the movable bed board is formed on the lower surface of the first variable mattress close to the expansion vehicle body;
[0014] One end of the movable bed board is fixed on the expansion vehicle body, and when the bed is in the expanded state, the other end of the movable bed board extends into the notch of the movable bed board.
[0015] Preferably, the first variable mattress includes an integrated thin mattress part and a thick mattress part along the sliding direction of the movable bed board, the upper surfaces of the thin mattress part and the thick mattress part are flush, and a notch part for accommodating the movable bed board is formed at the lower surface of the thin mattress part; in order to make up for the step of the overlapping part of the movable bed board and the fixed bed board, the first variable mattress adopts an unequal material thickness design, that is, a notch part is set on its lower surface, which can be integrated with the unequal height bed boards when stretched to ensure the flatness of the upper part of the mattress.
[0016] When the bed is in the expanded state, a movable space is reserved between the end of the movable bed board and the thick mattress part; the movable space is used to prevent the end of the movable bed board from contacting the thick mattress part during the rotation process of the RV.
[0017] Preferably, when the bed is in the expanded state, the upper surface of the movable bed board fits against the lower surface of the thin mattress part and the lower surface of the second variable mattress, and provides support for the thin mattress part and the second variable mattress.
[0018] There are many ways to achieve a slidable connection between the movable and fixed bedboards. A more practical method is to use a slide groove and a slider. Specifically, the upper surface of the fixed bedboard is provided with a slide groove along the expansion direction of the RV, and the lower surface of the movable bedboard is provided with a slider or roller that cooperates with the slide groove at a position corresponding to the slide groove.
[0019] The slider or the roller is installed on the slide groove so that the movable bed board can slide on the fixed bed board along the length direction of the slide groove.
[0020] Of course, the sliding can also be achieved by utilizing the cooperation between the slide rail and the roller, or by utilizing a gear or rack connection, which will not be described in detail here.
[0021] During the actual expansion and contraction process, it is necessary to position the final state of expansion or contraction. Positioning can be achieved by using the abutment between the expansion body and the fixed body, or by using the structure of the variable-length bed. For example, the abutment between the expansion body and the fixed bed board determines the final state of contraction, or the abutment between the movable bed board and the fixed mattress determines the final state of contraction. Alternatively, the cooperation between the chute and the slider can be used to position the expansion or contraction state. For example, when the slider or the roller is located in the chute close to one end of the fixed bed board, the bed is in the contracted state.
[0022] When the slider or the roller is located at the end of the slide groove away from the fixed bed board, the bed is in an expanded state.
[0023] Preferably, when the bed is in the expanded state, the upper surfaces of the fixed mattress, the first variable mattress and the second variable mattress are on the same plane;
[0024] The first hinge shaft is located near the upper surface of the fixed mattress, and the second hinge shaft is located near the lower surface of the second variable mattress.
[0025] The second variable mattress can be in a free state at one end away from the fixed bed board. In this case, when shrinking, the expansion body needs to be used to support the first and second variable mattresses. Similarly, the folding can also be achieved through the connection between the second variable mattress and the movable bed board, such as the second variable mattress is hinged to the movable bed board at one end away from the fixed bed board.
[0026] The present invention provides a variable-length recreational vehicle, comprising a vehicle body and the variable-length bed described above.
[0027] The beneficial effects produced by the technical solution of the present invention are as follows:
[0028] (1) The length of the bed can change with the expansion of the vehicle. When the bed is in the shortened state, it can ensure that the length of the vehicle meets the length limit of blue-plate vehicles, while providing more space for the arrangement of living facilities; when the vehicle is in the expanded state, the bed can be extended accordingly without affecting the use of other living facilities, while providing comfortable sleeping conditions, solving the disadvantage of the current folding beds or inflatable beds that require manual operation.
[0029] (2) By utilizing the sliding design of the fixed bed board and the movable bed board, and by coordinating the fixed mattress, the first variable mattress, and the second variable mattress, when the RV is in the expanded state, the bed can be extended accordingly without affecting the use of other living facilities, while providing comfortable sleeping conditions.

[0030] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. It should be understood that the following drawings only illustrate certain embodiments of the present invention and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying any creative work.

[0032] Figure 2 This is a schematic diagram of the structure of a preferred variable-length bed in the present invention in a collapsed state;
[0033] Figure 3 It is a schematic diagram of the sliding structure of the preferred fixed bed board and movable bed board of the present invention. DETAILED DESCRIPTION
[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.
[0035] Most of the beds in existing expandable RVs are folding beds or inflatable beds. When the sleep function is needed during parking and rest, after the vehicle length is expanded or retracted, the bed cannot be synchronously lengthened or retracted with the RV expansion mechanism. At this time, the driver needs to make a lengthening or retraction command, which is time-consuming and labor-intensive. That is, the folding bed and inflatable bed cannot be synchronously expanded and retracted with the RV expansion part.
[0036] like Figure 1-3 As shown, the variable-length bed for a motorhome includes a fixed bed board 1 and a movable bed board 2. The fixed bed board 1 is fixedly mounted on a fixed body 100 of the motorhome, and the movable bed board 2 is fixedly mounted on an extended body 200 of the motorhome. The movable bed board 2 is slidably mounted on the fixed bed board 1.
[0037] A fixed mattress 3 is fixed to the upper surface of the fixed bed board 1, in the area away from the expansion body 200. A first variable mattress 4 is hingedly attached to the side of the fixed mattress 3 closest to the expansion body 200. The other side of the first variable mattress 4 extends to the upper surface of the movable bed board 2 and is hingedly attached to a second variable mattress 5. The sliding design of the fixed and movable bed boards, coupled with their interaction with the fixed, first, and second variable mattresses, allows the bed to extend when the RV is in the expanded state, without affecting the use of other living facilities while providing comfortable sleeping conditions.
[0038] The RV expansion here can be expanded backward or to the left and right sides. When expanding backward, the fixed body 100 is the front body. Of course, in actual design, there is also a situation where the expansion body 200 and the fixed body 100 are swapped, that is, the expansion body 200 can also be kept fixed as the main part of the RV during expansion, while the fixed body 100 moves away from the expansion body 200 to achieve expansion, which is also within the scope of protection of the present invention.
[0039] In the contracted state, see Figure 2, the movable bed board is located on the side close to the fixed mattress. At this time, the first and second variable mattresses are in a retracted state, that is, the first and second variable mattresses are in a folded state, forming a triangular structure with the movable bed board; when the RV is expanded, the expansion body drives the movable bed board to move backward. At this time, the second variable mattress also extends backward under the action of gravity, and drives the first variable mattress to extend backward. The angle between the first and second variable mattresses gradually increases to 180 degrees. At this time, the RV is in the expanded state. Figure 1 .
[0040] Here, the fixed connection between the bed board and the vehicle body, and the mattress and the bed board can be in various forms, preferably using screw fixed connection, such as the fixed bed board 1 is fixed to the fixed vehicle body 100 by screws, the movable bed board 2 is fixed to the expanded vehicle body 200 by screws, and the fixed mattress 3 is fixed to the fixed bed board 2 by screws.
[0041] As a preferred embodiment, the fixed mattress 3 is hinged to the first variable mattress 4 through a first hinge shaft 6, and the first variable mattress 4 is hinged to the second variable mattress 5 through a second hinge shaft 7; and the first hinge shaft 6 is parallel to the second hinge shaft 7 and perpendicular to the sliding direction of the movable bed board 2.
[0042] As a preferred embodiment, the plane where the movable bed board 2 is located is parallel to the plane where the fixed bed board 1 is located; and a notch 401 for accommodating the movable bed board 2 is formed on the lower surface of the first variable mattress 4 close to the expansion body 200;
[0043] One end of the movable bed board 2 is fixed on the expansion body 200 , and when the bed is in the expanded state, the other end of the movable bed board 2 extends into the notch 401 of the movable bed board 2 .
[0044] As a preferred embodiment, the first variable mattress 4 includes an integrated thin mattress portion 41 and a thick mattress portion 42 along the sliding direction of the movable bed board 2. The upper surfaces of the thin mattress portion 41 and the thick mattress portion 42 are flush and a notch portion 401 for accommodating the movable bed board 2 is formed at the lower surface of the thin mattress portion 41; in order to make up for the step of the overlapping part of the movable bed board and the fixed bed board, the first variable mattress adopts an unequal material thickness design, that is, a notch portion is set on its lower surface, which can be integrated with the unequal height bed boards when stretched to ensure the flatness of the upper part of the mattress.
[0045] When the bed is in the expanded state, a movable space is reserved between the end of the movable bed board 2 and the thick mattress part 42; the movable space is used to prevent the end of the movable bed board 2 from contacting the thick mattress part 42 during the rotation process when the RV is folded.
[0046] As a preferred embodiment, when the bed is in the expanded state, the upper surface of the movable bed board 2 fits against the lower surface of the thin mattress part 41 and the lower surface of the second variable mattress 5, and provides support for the thin mattress part 41 and the second variable mattress 5.
[0047] In order to achieve the sliding connection between the movable bed plate and the fixed bed plate, there are many ways to choose. The more practical way is to achieve the sliding connection through the sliding groove and the slider. Specifically, the upper surface of the fixed bed plate 1 is provided with a sliding groove 11 along the expansion direction of the RV, and the lower surface of the movable bed plate 2 is provided with a slider 12 or a roller that matches the sliding groove 11 at a position corresponding to the sliding groove 11. Figure 3 ;
[0048] The slider 12 or roller is installed on the slide groove 11 so that the movable bed board 2 slides on the fixed bed board 1 along the length direction of the slide groove 11.
[0049] Of course, the sliding can also be achieved by utilizing the cooperation between the slide rail and the roller, or by utilizing a gear or rack connection, which will not be described in detail here.
[0050] During the actual expansion and contraction process, it is necessary to locate the final state of expansion or contraction. Positioning can be achieved by using the abutment between the expansion body and the fixed body, or by using the structure of the variable-length bed. For example, the abutment between the expansion body and the fixed bed board determines the final state of contraction, or the abutment between the movable bed board and the fixed mattress determines the final state of contraction. Alternatively, the cooperation between the chute and the slider can be used to locate the expansion or contraction state. For example, when the slider 12 or the roller is located in the chute 11 close to one end of the fixed bed board 1, the bed is in the contracted state.
[0051] When the slider 12 or the roller is located at the end of the slide groove 11 away from the fixed bed board 1, the bed is in an expanded state.
[0052] As a preferred embodiment, when the bed is in the expanded state, the upper surfaces of the fixed mattress 3, the first variable mattress 4 and the second variable mattress 5 are on the same plane;
[0053] The first hinge shaft 6 is located near the upper surface of the fixed mattress 3 , and the second hinge shaft 7 is located near the lower surface of the second variable mattress 5 .
[0054] The second variable mattress 5 can be in a free state at one end away from the fixed bed board 1. Then, when shrinking, it is necessary to use the support of the expansion body 200 to achieve the folding between the first variable mattress 4 and the second variable mattress 5. Similarly, the folding can also be achieved through the connection between the second variable mattress 5 and the movable bed board 2, such as the second variable mattress being hinged to the movable bed board at one end away from the fixed bed board.
[0055] This embodiment provides a variable-length RV, including a vehicle body and the above-mentioned variable-length bed, so that the length of the sleeping cabin can change as the vehicle is expanded. When in the non-expanded state, the bed is in a shortened state, which can ensure that the vehicle length meets the length limit of blue-plate vehicles while providing more space for arranging living facilities.
[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
