Detailed Implementation

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses a sofa frame and a sofa, wherein the sofa frame includes: a base frame 100, a seat support module 200, a lumbar support module 300, and a headrest module (not shown in the drawings); the base frame 100 is provided with a sliding groove 110; the seat support module 200 is slidably mounted on the sliding groove 110 assembly; the lumbar support module 300 has one end rotatably mounted and fixedly connected to the seat support module 200, and the other end rotatably mounted on the base frame 100; the headrest module has one end connected to the lumbar support module 300, and the other end is a movable end; both ends of the headrest module are foldable; wherein the seat support module 200 slides along the sliding groove 110, driving the lumbar support module 300 to rotate, so that the included angle between the seat support module 200 and the lumbar support module 300 is greater than 90 degrees.

[0036] Specifically, please refer to Figure 1 and Figure 2 In actual use, one end of the lumbar support module 300 is rotatably connected to the rear end of the seat support module 200, and the other end is rotatably connected to the rear end of the base frame 100. When the seat support module 200 slides toward the front end of the slide groove 110, it causes the two ends of the lumbar support module 300 to rotate in opposite directions: the end of the lumbar support module 300 connected to the seat support module 200 rotates toward the rear end of the base frame 100 (opposite to the seat support module 200), and the end of the lumbar support module 300 connected to the base frame 100 rotates toward the front end of the base frame 100 (in the same direction as the seat support module 200). As a result, the lumbar support module 300 tilts toward the rear end of the base frame 100 as a whole, and the angle between it and the seat support module 200 gradually increases. At the same time, one end of the headrest module is fixedly connected to the end of the lumbar support module 300 that is away from the seat support module 200. When the movable end of the headrest module is manually opened (unfolded toward the rear end of the base frame 100), a reclining position is achieved.

[0037] As can be seen, this application achieves the switching from a standard sitting posture to a reclining posture by sliding the seat support module 200 and causing the lumbar support module 300 to rotate, so that the lumbar support module 300 tilts towards the rear end of the base frame 100. Compared with a transmission electric sofa, this application eliminates the independent adjustment mechanism of the seat support module 200 and the lumbar support module 300, effectively avoiding the cumbersome operation for users when achieving a reclining posture.

[0038] In this embodiment, please refer to Figure 2 The seat support module 200 includes: a seat main frame 210 and a seat motor 220; the seat main frame 210 is slidably mounted on the slide groove 110; the seat motor 220 is located in the middle of the base frame 100 and is connected to the seat main frame 210 for transmission, so as to drive the seat main frame 210 to slide toward the front end of the slide groove 110, thereby driving the lumbar support module 300 to rotate.

[0039] In actual use, one end of the lumbar support module 300 is rotatably mounted on the rear end of the seat main frame 210, and the other end is rotatably mounted on the base frame 100. When the seat motor 220 drives the seat main frame 210 to move towards the front end of the slide groove 110, it also drives one end of the lumbar support module 300 to move towards the front end of the slide groove 110. At the same time, the end of the lumbar support module 300 connected to the seat main frame 210 rotates relative to the rear end of the slide groove 110, causing the angle between the lumbar support module 300 and the seat main frame 210 to gradually increase, thereby realizing the conversion from a sitting posture to a reclining posture. During this process, the lumbar support module 300 rotates and tilts towards the rear end of the base frame 100 under the drive of the seat main frame 210. The end of the lumbar support module 300 away from the seat main frame 210 undergoes compensatory rotation relative to the front end of the base frame 100, so that the lumbar support module 300 reaches the predetermined position and maintains a stable state.

[0040] As can be seen, in this embodiment, the lumbar support module 300 is rotatably connected to the seat main frame 210 and the base frame 100 at both ends. The seat main frame 210 is driven to slide by the seat motor 220, which drives the two ends of the lumbar support module 300 to rotate. The switch from a standard sitting posture to a zero-gravity reclining posture can be completed in a single operation, which improves the convenience of use and avoids the operational redundancy problem caused by the need to adjust each module multiple times in traditional electric sofas.

[0041] In another embodiment of this utility model, please refer to Figure 1 and Figure 2 The lumbar support module 300 includes a support rod 310 and a first rotating rod 320. One end of the support rod 310 is rotatably mounted on the seat main frame 210. One end of the first rotating rod 320 is rotatably mounted on the base frame 100, and the other end is rotatably mounted in the middle of the support rod 310. When the seat main frame 210 slides along the front end of the slide groove 110, it drives the support rod 310 to rotate toward the rear end of the slide groove 110, while the first rotating rod 320 rotates toward the front end of the slide groove 110.

[0042] Specifically, one end of the support rod 310 is rotatably mounted on the seat frame 210. When the seat motor 220 drives the seat frame 210 to move towards the front end of the slide groove 110, the support rod 310 rotates relative to the rear end of the slide groove 110, causing the angle between the support rod 310 and the seat frame 210 to gradually increase, thereby realizing the conversion from a sitting to a reclining posture. At the same time, the first rotating rod 320 rotates relative to the front end of the base frame 100 to compensate for the rotation, thereby enabling the support rod 310 to reach a predetermined position and maintain a stable state.

[0043] In this embodiment, please refer to Figure 2The seat support module 200 further includes a second rotating rod 230; one end of the second rotating rod 230 is connected to the rear end of the seat main frame 210, and the other end is rotatably disposed in the middle of the first rotating rod 320; when the seat main frame 210 moves toward the front end of the slide groove 110, it drives the second rotating rod 230 to move, thereby driving the first rotating rod 320 to rotate.

[0044] Specifically, when the seat motor 220 drives the seat main frame 210 to move toward the front end of the slide groove 110, the seat main frame 210 drives the support rod 310 to rotate relative to the rear end of the slide groove 110, and the second rotating rod 230 moves toward the front end of the slide groove 110. At the same time, the second rotating rod 230 also rotates relative to the rear end of the slide groove 110 to help the first rotating rod 320 rotate toward the front end of the slide groove 110 better, so that the support rod 310 can rotate smoothly to the predetermined position and remain stable, ensuring the overall stability of the sofa frame.

[0045] In another embodiment of this utility model, please refer to Figure 2 The seat support module 200 also includes a sliding rod 240; the sliding rod 240 is slidably mounted on the slide groove 110, and both ends of the sliding rod 240 are connected to the seat main frame 210; the seat motor 220 is drivenly connected to the sliding rod 240. In actual use, the sliding rod 240 is U-shaped, with its middle part slidably mounted on the slide groove 110 and both ends fixedly connected to the seat main frame 210; meanwhile, the seat motor 220 is a telescopic motor, with one end of the seat motor 220 located in the middle of the base frame 100 and the other end drivenly connected to the middle of the sliding rod 240. When the seat motor 220 is started, it drives the sliding rod 240 to move on the slide groove 110, thereby causing the seat main frame 210 to slide, which in turn causes the support rod 310 to rotate, realizing the switching of the sofa frame between sitting and reclining positions.

[0046] As can be seen, in this embodiment, the seat motor 220 drives the sliding rod 240 to make linear movements on the slide groove 110, realizing the switching between sitting and reclining postures. Compared with traditional electric sofas, this embodiment can complete the posture conversion with only one operation. At the same time, the conversion process is smooth and stable, ensuring the convenience of use.

[0047] In this embodiment, the angle between the support rod 310 and the seat frame 210 is 120-145 degrees; the sliding rod 240 slides along the slide groove 110 for a distance of 20-30 centimeters. Specifically, in actual use, the seat motor 220 drives the sliding rod 240 to slide 30 centimeters along the slide groove 110. At this time, the support rod 310 rotates toward the rear end of the slide groove 110 until the angle between the support rod 310 and the seat frame 210 is 130 degrees, thereby completing the switch from a sitting to a reclining position.

[0048] In another embodiment of this utility model, the headrest module is provided with a hinge; one end of the hinge is fixedly connected to the lumbar support module 300, and the other end is movably disposed. In actual use, one end of the headrest module is fixedly connected to the lumbar support module 300, and the other end is movably disposed and can be folded toward the lumbar support module 300. When the sofa frame is in a sitting position, the two ends of the headrest module are facing each other; when the sofa frame is switched to a reclining position, the movably disposed end of the headrest module can be manually pried open toward the rear end of the slide groove 110 (in the opposite direction to the sliding direction of the seat main frame 210) to better support the head.

[0049] Based on the above embodiments, this utility model also discloses a sofa, including the sofa frame described in any one of the above embodiments. In actual use, the sofa also includes a sofa cushion, which covers the base frame 100, seat support module 200, lumbar support module 300, and headrest module, improving comfort.
