[0001] This utility model relates to the field of smart home accessories, specifically a sliding sofa bed support. Background Technology

[0002] As people's living standards improve, furniture styles are becoming increasingly diverse, and smart home technology is becoming more and more widespread. However, existing smart home solutions also have some problems. For example, in the case of a sliding sofa bed, which typically has multiple usage scenarios—the frame can be folded up to function as a regular sofa, or the frame can be unfolded to form a reclining bed for increased comfort—instability can occur during the extension and retraction of the sofa bed frame. This can lead to vibrations, jamming, and abnormal noises between the guide rails and the seat cushion mounting plates, resulting in a poor customer experience. Therefore, there is an urgent need to develop a stable and smooth-moving sliding sofa bed frame. Summary of the Invention

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-6 As shown, a sliding sofa bed frame includes at least two guide rails 6, a sliding tube 7, a seat cushion mounting plate 4, and a driving device. The at least two guide rails 6 are arranged in parallel. The seat cushion mounting plate 4 is connected to the guide rails 6 through a sliding device. The driving device drives the seat cushion mounting plate 4 to slide along the guide rails 6 through the sliding tube 7. The sliding device includes several roller groups, each roller group including at least one roller 9 and at least one guide wheel 10. Both the roller 9 and the guide wheel 10 move within the guiding area of ​​the guide rail 6. The guide wheel 10 contacts the side wall of the guide rail 6, playing a guiding role and preventing the seat cushion mounting plate 4 from rubbing against the guide rail 6 during movement, thus avoiding vibration, jamming, and abnormal noise.

[0026] In this embodiment, in the roller assembly, rollers 9 and guide wheels 10 correspond one-to-one. The rollers 9 are rotatably disposed on the side of the seat cushion mounting plate 4, and the rotation axis of the rollers 9 is horizontally set. The guide wheels 10 are connected to the seat cushion mounting plate 4 through guide wheel mounting plate 11, and the rotation axis of the guide wheels 10 is vertically set.

[0027] In this embodiment, each seat cushion mounting support piece 4 has a set of rollers 9 at both ends, and each seat cushion mounting support piece 4 has at least one set of guide wheels 10.

[0028] In this embodiment, as Figure 6As shown, the guide rail 6 has a G-shaped cross-section. The guide rail 6 includes a top 12, an outer side wall 13, a bottom 14, and an inner side wall 15. These components are sequentially connected to form a guiding area. A gap is provided between the top 12 and the inner side wall 15 to allow space for the rotation shaft of the roller 9 and the mounting bracket 11 of the guide wheel. Both the roller 9 and the guide wheel 10 are located between the outer side wall 13 and the inner side wall 15. The G-shaped guide rail 6 ensures that the guide wheel 10 can be fixed without affecting the installation and use of the roller 9.

[0029] In this embodiment, the distance between the top 12 and the bottom 14 is the inner height of the guide rail, and the distance between the outer side wall 13 and the inner side wall 15 is the inner width of the guide rail. The difference between the inner height of the guide rail and the diameter of the roller 9 is less than 5mm, and the difference between the inner width of the guide rail and the diameter of the guide wheel 10 is less than 5mm. The size of the position gap can avoid the gap being too large and ensure the stable operation of the roller 9.

[0030] In this embodiment, the roller 9 also includes a roller washer 8 on its rotating shaft. The roller washer 8 is close to the side of the seat mounting support 4. The roller washer 8 is located between the guide rail 6 and the seat mounting support 4. The roller washer 8 is provided to prevent the seat mounting support 4 from rubbing against the inner wall 15 of the guide rail 6 during the movement of the roller 9.

[0031] In this embodiment, the guide wheel mounting bracket 11 is L-shaped, with its upper end connected to the side of the seat cushion mounting bracket 4. The guide wheel 10 is fixedly connected to the lower end of the guide wheel mounting bracket 11, extends into the guide rail 6 from the gap between the top 12 and the inner side wall 15, and is placed between the outer side wall 13 and the inner side wall 15.

[0032] In this embodiment, the lower end of the guide wheel mounting bracket 11 is provided with a threaded hole, and the rotating shaft of the guide wheel 10 has a bolt portion, which is fixed in the threaded hole of the guide wheel mounting bracket 11 by threaded engagement. The guide wheel 10 and the guide wheel mounting bracket 11 can also be connected by riveting, snap-fit ​​connecting columns, or other methods.

[0033] In this embodiment, the parallel guide rails 6 are fixedly connected by the connector 3 to form a stable fixed support. The driving device includes a driving guide rail 1 and a driving power device 2. The driving guide rail 1 is parallel to the guide rail 6. One end of the driving guide rail 1 is fixedly connected to the connector 3. The driving guide rail 1 is provided with an output end 5 that can move along the driving guide rail 1. The output end 5 is fixedly connected to the translation tube 7. The driving power device 2 drives the output end 5 to move back and forth along the driving guide rail 1.

[0034] In this embodiment, the driving power device 2 includes a drive motor, and the output end 5 is a sliding nut. The drive motor and the sliding nut are linked by a lead screw. The driving power device 2 also includes a cylinder and a hydraulic cylinder. This embodiment illustrates a lead screw and guide rail linkage method. In actual production, the transmission between the driving power device 2 and the output end 5 can also be achieved using a rack and pinion system, a linear motor, a cylinder driving the output end 5 to move, or a hydraulic cylinder driving the output end 5 to move.
