Detailed Implementation

[0032] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] Please refer to Figures 1-6 This embodiment provides a retractable folding bed for a motorhome, including a retractable bed frame. The retractable bed frame includes a first bed frame 1 and a second bed frame 2 that are slidably connected. The first bed frame 1 and the second bed frame 2 can slide relative to each other to adjust the size of the retractable bed frame. The first bed frame 1 is rotatably provided with a first support leg 3, wherein the first support leg 3 can be rotatably connected to the first bed frame 1 through hinges, pins, etc. The first support leg 3 is used to install on the motorhome and support the first bed frame 1. The second bed frame 2 is rotatably provided with a second support leg 4, which is used to support the second bed frame 2.

[0035] During actual installation, the first support leg 3 can be fixedly installed on the RV, and the retractable folding bed can be installed close to a wall or cabinet. When folding for storage, the user can slide the second bed frame 2 along the first bed frame 1 to minimize the size of the retractable bed frame, rotate the second support leg 4 along the retractable bed frame to bring the second support leg 4 closer to the bottom of the retractable bed frame, and simultaneously rotate the retractable bed frame upwards along the first support leg 3 to bring the retractable bed frame to a vertical position. After folding for storage, it is as follows: Figure 3 As shown, the telescopic bed frame can be placed close to the wall or cabinet. When not in use, the telescopic folding bed can be compactly stored, significantly reducing the overall thickness. When installed against the wall or embedded in the wall, it does not affect the interior space layout.

[0036] When needed, the telescopic bed frame can be pulled down to rotate it to a horizontal position, while simultaneously rotating the second support leg 4 to a vertical position. After the second support leg 4 is rotated down, it is placed on the RV. The second support leg 4 supports the second bed frame 2, and the first support leg 3 supports the second bed frame 2. When unfolded, it is as follows: Figure 1 and Figure 2 As shown, it can be quickly unfolded into a stable and comfortable bed. The second bed frame 2 can be slid to adjust the size of the telescopic bed frame as needed, adapting to different heights or space conditions. The telescopic folding bed provided by this utility model is not only simple in structure and easy to operate, but also has good load-bearing capacity and reliability. It is suitable for the needs of efficient space utilization and functional diversity in mobile scenarios such as RVs, improving the user's living experience and space utilization efficiency.

[0037] Preferably, a slide rail 8 is provided between the outer side wall of the first bed frame 1 and the inner side wall of the second bed frame 2 in this embodiment. The slide rail 8 can be a commonly used three-section rail. By setting the slide rail 8, the stability of sliding between the first bed frame 1 and the second bed frame 2 can be improved.

[0038] Example 2

[0039] like Figures 4-6 As shown, based on Embodiment 1, the second bed frame 2 in this embodiment is provided with a limiting groove 5 at its top, and the first bed frame 1 slides through the limiting groove 5; the limiting groove 5 in this embodiment is used to limit the sliding of the first bed frame 1, thereby improving the sliding accuracy and stability of the first bed frame 1.

[0040] The first bed frame 1 is provided with multiple first bed boards 6 at intervals, and the first bed boards 6 slide against the top of the second bed frame 2; the second bed frame 2 is provided with multiple second bed boards 7 at intervals, and the second bed boards 7 slide against the top of the first bed frame 1. In this embodiment, the first bed boards 6 slide against the top of the second bed frame 2, so that the second bed frame 2 can provide auxiliary support for the first bed boards 6; the second bed boards 7 slide against the top of the first bed frame 1, so that the first bed frame 1 can provide auxiliary support for the second bed boards 7. When they support each other, the strength and load-bearing capacity of the telescopic bed frame after it is unfolded can be improved, making it safer to use. Preferably, in this embodiment, the first bed boards 6 and the second bed boards 7 are arranged alternately, so that the support points of the first bed boards 6 and the second bed boards 7 are evenly distributed, which can improve their support capacity.

[0041] Example 3

[0042] like Figure 1 , Figure 2 , Figures 7-9As shown, based on Embodiment 1, a limiting bracket is provided between the second bed frame 2 and the second support leg 4 in this embodiment. The limiting bracket is used to limit the rotation angle between the second bed frame 2 and the second support leg 4.

[0043] The limiting bracket includes a fixed frame 10, a rotating frame 11, an upper pull rod 12, and a lower pull rod 13. The fixed frame 10 is fixedly mounted on the second bed frame 2, and the rotating frame 11 is fixedly mounted on the second support leg 4. The top of the rotating frame 11 is rotatably connected to the fixed frame 10 via a pin. The top of the upper pull rod 12 is rotatably connected to the fixed frame 10 via a pin, and the bottom of the upper pull rod 12 is rotatably connected to the top of the lower pull rod 13 via a pin. The bottom of the lower pull rod 13 is movably connected to the rotating frame 11.

[0044] In this embodiment, the limiting bracket limits the angle between the second bed frame 2 and the second support leg 4 after the telescopic folding bed is unfolded. In this embodiment, the limiting bracket restricts the second support leg 4 from unfolding 90° relative to the second bed frame. That is, when the second bed frame 2 is rotated to a horizontal position for use, the second support leg 4 is rotated to a vertical position. At this time, the plane of the second bed frame 2 is perpendicular to the axis of the second support leg 4, the axis of the fixed frame 10 is perpendicular to the axis of the rotating frame 11, and the axis of the upper pull rod 12 is parallel to the axis of the lower pull rod 13. The upper pull rod 12 and the lower pull rod 13 form a straight line and together with the fixed frame 10 and the rotating frame 11, they form a right-angled triangle structure. Through the pull of the upper pull rod 12 and the lower pull rod 13, the fixed frame 10 and the rotating frame 11 cannot continue to rotate relative to each other. In this way, the fixed frame 10 and the rotating frame 11 can be kept at a 90° position for use, preventing the second support leg 4 from rotating too much.

[0045] Preferably, the fixing frame 10 in this embodiment is provided with a first receiving groove 14 for accommodating the upper pull rod 12; the upper pull rod 12 is provided with a second receiving groove 15 for accommodating the lower pull rod 13; the rotating frame 11 is provided with a third receiving groove 16 for accommodating the fixing frame 10. Thus, when the telescopic folding bed is folded and stored, the upper pull rod 12 can rotate into the first receiving groove 14, the lower pull rod 13 can rotate into the second receiving groove 15, and the fixing frame 10 is embedded in the third receiving groove 16. This facilitates storage and allows the second support leg 4 to be stored closer to the telescopic bed frame, reducing the thickness of the folded telescopic folding bed.

[0046] Example 4

[0047] like Figures 7-9As shown, based on Embodiment 3, in this embodiment, a slider 17 is provided between the bottom of the pull rod 13 and the rotating frame 11. The slider 17 is slidably disposed on the rotating frame 11. A tension spring 18 is provided between the slider 17 and the rotating frame 11. The tension spring 18 is used to apply a pulling force to the slider 17 towards the fixed frame 10. The slider 17 is provided with a limiting step 19. A push rod 20 is provided between the slider 17 and the pull rod 13. One end of the push rod 20 is rotatably connected to the slider 17 via a pin, and the other end of the push rod 20 is rotatably connected to the pull rod 13 via a pin.

[0048] When the plane of the second bed frame 2 is perpendicular to the axis of the second support leg 4, the bottom of the pull rod 13 abuts against the top of the limiting step 19, and the axis of the push rod 20 is perpendicular to the axis of the second support leg 4. The bottom of the slider 17 is provided with a pull tab 22, which is located below the bottom of the pull rod 13.

[0049] like Figure 9 As shown in (a), when the telescopic folding bed is unfolded and in use, the push rod 20 is in a horizontal state. At this time, the push rod 20 provides lateral support to the pull rod 13, preventing the pull rod 13 from rotating toward the rotating frame 11. This prevents the rotating frame 11 from rotating counterclockwise for storage, making it easier to keep the telescopic folding bed stably unfolded for use.

[0050] When the telescopic folding bed needs to be folded and stored, the user can pull down the pull tab 22. The pull tab 22 causes the slider 17 to slide down, which disrupts the current stable state. The slider 17 sliding down pulls the left end of the push rod 20 downwards. As a result, the push rod 20 rotates along the slider 17, and the angle between the push rod 20 and the slider 17 rotates from the stable state of 90° to less than 90°. At the same time, the right end of the push rod 20 pulls the lower pull rod 13 towards the rotating frame 11 for storage, while the upper pull rod 12 rotates towards the fixed frame 10 for storage. Finally, the rotating frame 11 rotates towards the fixed frame 10 for storage. After storage, it looks like... Figure 9 As shown in (b), this facilitates the rotation of the second support leg 4 to close to the telescopic bed frame to complete the storage process, making the operation convenient.

[0051] When the telescopic folding bed is unfolded, the second support leg 4 is pulled outward. During the process of the second support leg 4 rotating 90° relative to the telescopic bed frame, the tension spring 18 applies a pulling force to the slider 17 towards the fixed frame 10. Under the pull of the force, the slider 17 slides upward until the second support leg 4 rotates 90° relative to the telescopic bed frame. At this point, the bottom of the pull rod 13 abuts against the top of the limiting step 19. The limiting step 19 limits the bottom of the pull rod 13 to prevent it from continuing to rotate. At the same time, the push rod 20 rotates to the position shown in the image. Figure 9As shown in (a), the second support leg 4 is in a horizontal state, at which point an equilibrium point is reached and all positions stop rotating, so that the second support leg 4 can stay in this position to support the second bed frame 2.

[0052] As a preferred implementation method, such as Figure 8 As shown, the pull rod 13 is provided with a fourth receiving groove 21, which is used to accommodate the slider 17 and the push rod 20. In this way, when the telescopic folding bed is folded and stored, the slider 17 and the push rod 20 can be moved and embedded into the fourth receiving groove 21 for storage, which makes it easier for the fixed frame 10 and the rotating frame 11 to be close to each other for storage, reducing the thickness after storage.

[0053] Example 5

[0054] like Figures 1-3 As shown, based on Embodiment 1, this embodiment further includes a gas spring 9. One end of the gas spring 9 is rotatably connected to the first bed frame 1, and the other end of the gas spring 9 is rotatably connected to the first support leg 3. In this embodiment, the gas spring 9 is used to buffer the rotation of the first bed frame 1 during the unfolding and folding of the telescopic folding bed, making it easier for the user to operate.
