Description

Technical Field

[0001] This application relates to the technical field of RV furniture, and in particular to a bed frame structure for an RV. Background Technology

[0002] With economic development and the improvement of people's living standards, RV travel has become a lifestyle. However, the interior space of RVs is generally small, and can only accommodate limited living facilities and small beds. Especially when a family travels, the bed area in the RV may not be sufficient for their needs.

[0003] Therefore, in related technologies, within the limited space of a motorhome, the rest area and activity area are usually converted into different functions at different times. The space used for activities during the day is used as a rest area by placing a bed board at night.

[0004] However, this design makes the bed board bulky and heavy, which is inconvenient to unfold and store. It usually requires two people to operate, and it is time-consuming and laborious. Summary of the Invention

[0005] To improve the storage convenience of RV bed frames, this application provides a bed frame structure for RVs.

[0006] This application provides a bed frame structure for a motorhome, employing the following technical solution:

[0007] A bed frame structure for a motorhome includes a basic bed frame, the basic bed frame including a fixed frame and a movable frame, one end of the fixed frame being open, and the movable frame being slidably connected to the fixed frame in a direction perpendicular to the opening;

[0008] A fixed side plate is fixed to the top of the fixed frame on the side away from the opening, and a movable side plate located outside the fixed frame is fixed to the top of the movable frame on the side away from the fixed side plate.

[0009] The top of the fixed frame is fixed with multiple parallel first ribs, the length direction of the first ribs is along the moving direction of the movable frame, and the movable side plate is fixed with multiple second ribs parallel to the first ribs, the second ribs and the first ribs are offset from each other;

[0010] One end of the first rib is fixed to the fixed side plate, and the other end is connected to a connecting strip. The end of the second rib away from the movable side plate is fixedly connected to a movable strip for abutting against the connecting strip.

[0011] By adopting the above technical solution, the user drags the movable frame, causing it to slide relative to the fixed frame. This, in turn, causes the upper movable strip to slide relative to the fixed frame, thereby enabling the staggered first and second ribs to retract and expand. When the user drags the movable frame until the movable strip abuts against the connecting strip, the area of ​​the basic bed frame increases; when the user drags the movable frame until the movable strip abuts against the fixed side panel, the area of ​​the basic bed frame decreases. The operation is simple and convenient, and the retraction and expansion of the basic bed frame can be achieved quickly. When the user is resting, the basic bed frame can be expanded to provide more sleeping space; when not resting, the basic bed frame can be retracted to save usable space inside the RV.

[0012] Optionally, both ends of the first rib and the second rib are fitted with rubber sleeves, and both ends of the first rib and the second rib are provided with fasteners for fixing the positions of the first rib and the second rib.

[0013] By adopting the above technical solution, positioning ridges are set on the fixed side plate and the movable side plate, providing fixing points for fixing the first rib and the second rib, so that the first rib and the second rib can be firmly fixed on the fixed frame and the movable frame; rubber sleeves are set at both ends of the first rib and the second rib to provide cushioning for the first rib, the second rib, the positioning ridge and the movable strip, reducing the possibility of wear on the first rib, the second rib, the positioning ridge and the movable strip, and thus increasing the service life of the basic bed frame.

[0014] Optionally, storage cabinets are provided at both ends of the basic bed frame. The storage cabinets include an outer cabinet and an inner cabinet. The outer cabinet is hollow and open at one end. The inner cabinet is slidably connected to the inside of the outer cabinet. When the fixed frame and the movable frame slide relative to each other, they can drive the outer cabinet and the inner cabinet to slide relative to each other.

[0015] By adopting the above technical solution, storage cabinets are set at both ends of the basic bed frame, which increases the storage space of the RV. The built-in cabinets can slide into the outer cabinet, thereby realizing the retraction and unfolding of the storage cabinets. This not only increases the storage space in the RV, but also does not take up too much space in the RV.

[0016] Optionally, the basic bed frame is provided with connecting handles at both ends, one end of which is fixedly connected to the basic bed frame and the other end is fixedly connected to the storage cabinet.

[0017] By adopting the above technical solution, users can drag the connecting handle to simultaneously unfold and retract the basic bed frame and storage cabinet, which is convenient to operate and improves usage efficiency.

[0018] Optionally, the built-in cabinet has a storage cavity on the side away from the base bed frame, and a passage opening is provided at the end of the built-in cabinet closest to the base bed frame, the passage opening communicating with the storage cavity;

[0019] The storage cavity is equipped with a folding plate, which can be pulled out from the channel opening and laid on top of the fixed frame or the movable frame.

[0020] By adopting the above technical solution, when the user does not need the basic bed frame as a sleeping space, the mattress can be stored in the built-in cabinet, and the folding board set in the storage cavity can be pulled out from the passage and laid on top of the basic bed frame, thus turning the basic bed frame into an entertainment space where the user can play on the folding board.

[0021] Optionally, the folding plate includes multiple folding unit plates connected end to end, with adjacent folding unit plates rotatably connected. A clearance groove is provided at the bottom of the folding unit plate, and a support foot is rotatably provided in the clearance groove.

[0022] By adopting the above technical solution, the folding panel can be pulled out from the passage more easily. Each folding panel unit is equipped with a rotating support leg. When the storage cabinet is in the unfolded state, the folding panel can be pulled out from the passage and the support leg can be rotated to a position perpendicular to the folding panel unit. The support leg is located in the gap between the first rib or the gap between the second rib, providing support for the folding panel. When the storage cabinet is in the retracted state, the support leg is rotated into the clearance groove, and the folding panel is laid on the base bed frame to provide entertainment space for the user.

[0023] Optionally, a mattress is installed inside the built-in cabinet, and a drive component is provided between the tops of the two storage cabinets for driving the mattress to be laid flat on the base bed frame or storing the mattress in the built-in cabinet.

[0024] By adopting the above technical solution, mattresses are installed in the built-in cabinets on both sides of the basic bed frame. When the basic bed frame is in the retracted state, the user can lay the mattress on only one side of the basic bed frame using the drive assembly to meet their resting needs; when the basic bed frame is in the extended state, the user can lay the mattresses on both sides of the basic bed frame using the drive assembly to meet their resting needs. The drive assembly eliminates the need for users to carry heavy mattresses themselves, saving manpower.

[0025] Optionally, the drive assembly includes multiple slide rails for fixing to the interior wall of the RV. The multiple slide rails are horizontally arranged and their length direction is perpendicular to the storage cabinet. Each slide rail is provided with a drive component. The drive component includes a first drive source that can move along the length direction of the slide rail and a hook that achieves vertical lifting and lowering through the first drive source.

[0026] The mattress is provided with flexible hanging rings for the hooks to fasten.

[0027] By adopting the above technical solution, when the mattress is laid flat on the base bed frame using the drive assembly, the user connects the hook to the two hanging rings at one end of the mattress. The first drive source drives the hook to rotate and lower the mattress onto the base bed frame, thus laying the mattress. When the mattress needs to be stored in the built-in cabinet, the user connects the hook to one end of the mattress. The first drive source drives the mattress to rotate and rise to a vertical position. The user then pushes the mattress into the built-in cabinet, thus completing the storage of the mattress. This saves time and effort and greatly reduces the burden on the user when moving the mattress.

[0028] Optionally, the outer cabinet includes a functional panel near the base bed frame. The functional panel includes a vertical base plate and a rotating plate rotatably connected to the base plate. The rotating plate can be rotated to a horizontal position and fixed, and the side of the rotating plate away from its rotating end is detachably connected to the base plate.

[0029] By adopting the above technical solution, when the user is sleeping or playing on the bed frame, the rotating board can be rotated to be perpendicular to the base board, and the rotating board can be used as a table; when not in use, the rotating board can be rotated to be coplanar with the base board, reducing the space occupied.

[0030] In summary, this application includes at least one of the following beneficial effects:

[0031] 1. The basic bed frame of this application can be retracted and unfolded, which can provide users with a spacious sleeping space without taking up too much usable space in the RV;

[0032] 2. The mattress uses a drive mechanism for automatic deployment and storage, saving time and effort and improving the user experience. Furthermore, the mattress can be stored in the built-in cabinets at both ends of the basic bed frame for easy organization and storage, preventing soiling.

[0033] 3. The basic bed frame can be used as a bed for sleeping, or a folding board can be laid on top to form a tatami-like area for users to play, making the space a multi-functional area and improving the space utilization rate;

[0034] 4. The first and second ribs are made of wood, which improves the breathability of the basic bed frame and makes the user's sleep experience better. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0043] The embodiments of this application disclose a bed frame structure for a motorhome, referring to... Figure 1 and Figure 2 A bed frame structure for a motorhome includes a basic bed frame 1, which comprises a fixed frame 11 and a movable frame 12. One end of the fixed frame 11 is open, and the movable frame 12 is slidably connected to the fixed frame 11 along a direction perpendicular to the opening. A fixed side plate 111 is fixedly mounted on the top of the fixed frame 11 on the side away from the opening, and the fixed side plate 111 is perpendicular to and fixedly connected to the fixed frame 11. A movable side plate 121 is fixedly mounted on the top of the movable frame 12 on the side away from the fixed side plate 111, and the movable side plate 121 is perpendicular to and fixedly connected to the movable frame 12. Supports are provided between the fixed frame 11 and the movable frame 12 and the motorhome floor.

[0044] Reference Figure 1 and Figure 2Positioning ribs 14 are fixedly provided on the fixed side plate 111 and the movable side plate 121. Multiple first ribs 112 are fixedly connected to the positioning ribs 14 of the fixed side plate 111, and multiple second ribs 122 are fixedly connected to the positioning ribs 14 of the movable side plate 121. The multiple first ribs 112 and second ribs 122 are arranged parallel to each other at intervals, and adjacent first ribs 112 and second ribs 122 are staggered. A connecting strip 113 is fixedly connected to the end of the first rib 112 away from the fixed side plate 111; a movable strip 123 is fixedly connected to the end of the second rib 122 away from the movable side plate 121. The movable strip 123 is disposed on the top plate of the fixed frame 11 and can slide on the top plate of the fixed frame 11, and the connecting strip 113 is disposed on the top plate of the movable frame 12 and can slide on the top plate of the movable frame 12.

[0045] Reference Figure 2 and Figure 3 Pulling the movable frame 12 moves it away from the fixed side panel 111 along the length of the second rib 122 until the connecting strip 113 and the movable strip 123 abut against each other. At this point, the bed frame structure is in an unfolded state, providing a larger sleeping space for the user. Outside of rest periods, the user can push the movable frame 12 until the movable strip 123 abuts against the positioning ridge 14 on the fixed side panel 111. At this point, the bed frame structure is in a retracted state, reducing the space occupied by the bed frame inside the RV. Both the first rib 112 and the second rib 122 are curved wooden strips, which offer better breathability and elasticity, providing a better sleeping experience. The manufacturer can also adjust the maximum load-bearing capacity of the basic bed frame 1 by appropriately setting the spacing between the first rib 112 and the second rib 122.

[0046] Reference Figure 2 and Figure 3 All first ribs 112 and second ribs 122 are provided with fasteners 15 at both ends, which can be self-tapping screws. The first rib 112 is fixedly connected to the positioning ridge 14 and the connecting strip 113 at both ends through the fasteners 15, and the second rib 122 is fixedly connected to the positioning ridge 14 and the movable strip 123 through the fasteners 15. Rubber sleeves 13 are also fitted at both ends of the first ribs 112 and second ribs 122. The rubber sleeves 13 prevent direct contact between the first rib 112 and the positioning ridge 14, between the first rib 112 and the connecting strip 113, between the second rib 122 and the positioning ridge 14, and between the second rib 122 and the movable strip 123, thereby reducing the possibility of wear on the first rib 112, the second rib 122, the positioning ridge 14, the connecting strip 113, and the movable strip 123.

[0047] Reference Figure 4The basic bed frame 1 has storage cabinets 2 at both ends. Each storage cabinet 2 includes an outer cabinet 21 and an inner cabinet 22. The outer cabinet 21 at one end of the basic bed frame 1 and the inner cabinet 22 at the other end are aligned. The outer cabinet 21 is hollow and open at one end, while the inner cabinet 22 is slidably connected inside it. Two connecting handles 3 are provided between the storage cabinets 2 and the basic bed frame 1. One connecting handle 3 is fixedly connected at one end to the movable frame 12 and at the other end to the outer cabinet 21 at one end of the basic bed frame 1; the other connecting handle 3 is fixedly connected at one end to the movable frame 12 and at the other end to the inner cabinet 22 at one end of the basic bed frame 1. When the user pulls either connecting handle 3, the movable frame 12, the outer cabinet 21 at one end of the basic bed frame 1, and the inner cabinet 22 at the other end of the basic bed frame 1 can be moved simultaneously, thus enabling the bed frame structure to retract and unfold.

[0048] Reference Figure 4 The storage cabinet 2 has a drive assembly 7 on its top. The drive assembly 7 includes three slide rails 71, which are fixedly connected to the roof of the RV. Each slide rail 71 has a sliding drive component 72, which includes a first drive source 721 and a hook 722. The first drive source 721 can be an electric hoist, and the hook 722 is fixedly connected to the first drive source 721. The drive component 72 can move along the length of the slide rail 71 under the drive of the first drive source 721, and the first drive source 721 can also drive the hook 722 to move vertically up and down.

[0049] Reference Figure 4 Each of the two built-in cabinets 22 contains a mattress 6. The length and width of the mattress 6 are the same as the length and width of the retracted base bed frame 1. The mattress 6 is placed vertically inside the built-in cabinet 22, and two flexible hanging rings 61 are fixedly installed on the mattress 6. The position of the hanging rings 61 corresponds to the position of the slide rails 71. The hanging rings 61 can be strips of soft fabric. When the user needs to rest, the storage cabinet 2 and the base bed frame 1 are unfolded, and the hooks 722 on the two slide rails 71 are fastened to the two hanging rings 61 on one of the mattresses. The first drive source 721 is activated, and the drive component 72 drives the mattress 6 to rotate and descend onto the base bed frame 1. If more sleeping space is needed, after one mattress 6 is laid out, the hooks 722 are removed and returned to their original height. The two hooks 722 on the other mattress 6, which are in opposite positions, are connected, and the mattress 6 is driven to rotate and descend onto the base bed frame 1 again.

[0050] Reference Figure 4 When the user needs to store the mattress 6 into the built-in cabinet 22, the mattress 6 can be rotated and raised to a vertical position in the same way, and the hook 722 can be raised further until the mattress 6 is aligned with the built-in cabinet 22. The user can then push the mattress 6 into the built-in cabinet 22 to quickly store the mattress 6. During this process, there is no need to manually move the mattress 6, making the operation convenient and labor-saving.

[0051] Reference Figure 4 When the storage cabinet 2 and the base bed frame 1 are in the unfolded state, the mattress 6, placed vertically inside the built-in cabinet 22, is at risk of falling onto the base bed frame 1. To reduce the possibility of the mattress 6 falling, safety buckles 222 are installed on both side walls of the built-in cabinet 22, and the safety buckles 222 are rotatably connected to the built-in cabinet 22. When the mattress 6 needs to be placed in the built-in cabinet 22, the safety buckles 222 are rotated to a horizontal position and abut against the surface of the mattress 6 near the base bed frame 1, thereby limiting the movement of the mattress 6; when the mattress 6 needs to be removed, the safety buckles 222 are rotated to a vertical position, allowing the mattress 6 to be removed.

[0052] Reference Figure 4 and Figure 5 The storage cabinet 2 and the side wall of the RV together form two storage cavities 4. The storage cavities 4 are located on the side of the two built-in cabinets 22 away from the basic bed frame 1. Each of the two built-in cabinets 22 has a passageway 221 on its side wall, which communicates with the storage cavity 4. The storage cavity 4 on the side where the connecting handle 3 is connected to the built-in cabinet 22 is equipped with a track 41 and a folding plate 5. The track 41 is fixedly connected to the top of the RV. Two lifting ropes 53 are installed between the folding plate 5 and the track 41. One end of the lifting rope 53 is fixedly connected to the folding plate 5, and the other end of the lifting rope 53 is fixedly connected to a second drive source 54. The second drive source 54 can be a small household winch. The second drive source 54 is fitted on the track 41 and can slide along the track 41. One of the second drive sources 54 is fixedly connected to the built-in cabinet 22. When the user pushes the connecting handle 3 to retract the bed frame structure, the folding plate 5 on that side slides along the track 41 with the built-in cabinet 22 to the rear of the outer cabinet 21 on that side. The other storage compartment 4 contains only a folding panel 5, and a lifting rope 53 and a second drive source 54 are provided between the folding panel 5 and the roof of the RV.

[0053] Reference Figure 4 and Figure 6The folding plate 5 comprises multiple folding plate units 51 connected end-to-end. Adjacent folding plate units 51 are rotatably connected by pins, and the area of ​​each folding plate unit 51 is smaller than the area of ​​the passage opening 221, allowing the folding plate 5 to be pulled out from the passage opening 221. The length of the folding plate 5 is the same as the length of the base bed frame 1. Each folding plate unit 51 has a clearance groove 55 at its bottom, within which a support leg 52 is rotatably mounted. The support leg 52 is rotatably connected to the folding plate unit 51 by a pin. A magnetic sheet is fixed to the side of the folding plate unit 51 where the support leg 52 is located. The magnetic sheet is not shown in the figure. The support leg 52 is made of metal. When the base bed frame 1 and storage cabinet 2 are in the unfolded state, the user can pull out the folding panel 5 from the passage 221 and rotate the support leg 52 to a position perpendicular to the folding panel unit 51. At this time, the support leg 52 is located in the gap between the first rib 112 or the gap between the second rib 122. The setting height of the support leg 52 is the same as the distance between the first rib 112 and the top plate of the fixed frame 11, or the distance between the second rib 122 and the top plate of the movable frame 12. After the user pulls out the folding panel 5, the folding panel 5 is laid flat on the base bed frame 1, allowing the user to play on the folding panel 5. If the base bed frame 1 and the storage cabinet 2 are in the retracted state, a movable plate 213 coaxial with the passage 221 on the outer cabinet 21 at one end of the base bed frame 1 is provided. The movable plate 213 can rotate relative to the outer cabinet 21. The user can pull the folding plate 5 on the side of the outer cabinet 21 where the movable plate 213 is provided. When the folding plate 5 is pulled out, the support leg 52 is in the retracted state. The folding plate 5 can be directly laid on the first rib 112 and the second rib 122, which can also be used by the user for play.

[0054] Reference Figure 4 and Figure 5 The outer cabinet 21 includes a functional panel near the base bed frame 1. The functional panel includes a vertical base plate 212 and a rotating plate 211 rotatably connected to the base plate 212. The base plate 212 and the rotating plate 211 are on the same plane. The rotating plate 211 is rotatably connected to the base plate 212 via hinges, and the rotating plate 211 can be rotated to a horizontal position and fixed. A latch 214 is provided on the side of the rotating plate 211 away from its rotating end, which locks the rotating plate 211 to the base plate 212. Users can rotate the rotating plate 211 to a position perpendicular to the base plate 212, at which point the rotating plate 211 functions as a table where users can eat or entertain themselves. For everyday use, the rotating plate 211 can be rotated to be coplanar with the base plate 212 and locked to the base plate 212 using the latch 214, reducing the space occupied by the rotating plate 211.

[0055] The implementation principle of the RV bed frame structure in this embodiment is as follows: When the user needs to rest, pull the connecting handle 3, which causes the movable frame 12, the outer cabinet 21 at one end of the base bed frame 1, and the inner cabinet 22 at the other end of the base bed frame 1 to slide until the connecting strip 113 and the movable strip 123 abut against each other. At this time, the bed frame structure of this application is in the unfolded state. Hang the hooks 722 on the two slide rails 71 into the hanging rings 61, rotate the safety buckles 222 on both sides of the mattress 6 until the mattress 6 can be removed, start the first drive source 721, and the first drive source 721 drives the mattress 6 to be laid on the base bed frame 1. After one mattress 6 is laid, remove the hooks 722 and reset the hooks 722. Using the two hooks 722 corresponding to the position of the other mattress 6, lay the other mattress 6 on the base bed frame 1 in the same way, and the user can rest.

[0056] When no rest is needed, the first drive source 721 drives the hook 722 to suspend the mattress 6 in the air. The user gently pushes the suspended mattress 6 into the built-in cabinet 22 and fastens the safety buckle 222 to complete the storage of the mattress 6. At this time, push the connecting handle 3 to make the movable frame 12 slide on the fixed frame 11 until the movable frame 12 abuts against the fixed side plate 111, so that the basic bed frame 1 can be folded and retracted.

[0057] When users want to play on the bed frame structure of this application, they can unfold the bed frame structure and pull out the two folding panels 5 from the passage 221. After being pulled out, the support legs 52 are unfolded and supported on the top plate of the movable frame 12 and the top plate of the fixed frame 11. At this time, users can play on the flat folding panels 5.

[0058] After the bed frame structure is retracted, the movable panel 213 on the outer cabinet 21 can be opened, allowing the folding panel 5 at one end of the basic bed frame 1 to be pulled out from the movable panel 213 and the passageway 221. Since the first rib 112 and the second rib 122 are arranged in an alternating pattern when the bed frame structure is retracted, there is no need to unfold the legs 52; the folding panel 5 can be placed directly on top of the first rib 112 and the second rib 122, allowing the user to play on the folding panel 5.

[0059] When a user needs a table while sleeping or playing, they can unfasten the buckle 214 on the top of the rotating plate 211 and rotate the rotating plate 211 to a position perpendicular to the base plate 212, and then use the rotating plate 211 as a table.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
