Detailed Implementation

[0036] 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.

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] This embodiment discloses a sofa frame, comprising: a base frame 100, a seat support module 200, a footrest module 300, and a lumbar support module 400; the base frame 100 is provided with a sliding groove 112 assembly; the seat support module 200 is slidably disposed on the sliding groove 112 assembly; the footrest module 300 is rotatably disposed at the front end of the seat support module 200; the lumbar support module 400 has one end rotatably disposed at the rear end of the seat support module 200, and the other end rotatably disposed on the base frame 100; wherein, when the seat support module 200 slides along the sliding groove 112 assembly, it can drive the footrest module 300 and the lumbar support module 400 to rotate synchronously, so that the position of the footrest module 300 is higher than the position of the lumbar support module 400.

[0039] Please see Figure 1 and Figure 2 In this embodiment, the end of the slide groove 112 assembly near the lumbar support module 400 is the first end, and the end away from the lumbar support module 400 is the second end. During use, the sofa frame moves as follows: when the seat support module 200 slides from the first end (near the lumbar support module 400) of the slide groove 112 assembly toward the second end (away from the lumbar support module 400), the end of the lumbar support module 400 connected to the seat support module 200 rotates toward the rear end of the base frame 100, while the end of the lumbar support module 400 connected to the base frame 100 rotates toward the front end of the base frame 100, thus lowering the overall height of the lumbar support module 400; simultaneously, the footrest module 300 rotates, unfolding towards the oblique front end of the seat support module 200, at which point the position of the footrest module 300 is higher than the position of the lumbar support module 400.

[0040] Specifically, please refer to Figure 1 and Figure 2 When the electric sofa is extended, the seat support module 200 extends forward toward the first end of the slide rail 112 assembly, causing the footrest module 300 to rotate and extend forward. The lumbar support module 400 rotates toward the rear end of the base frame 100. At the same time, the height of the footrest module 300 gradually increases, and the height of the lumbar support module 400 gradually decreases. Finally, the height of the footrest module 300 is higher than that of the lumbar support module 400, achieving a zero-gravity state for the sofa.

[0041] In this embodiment, the slide groove 112 assembly includes a slide rail 111 and a slide groove 112; a slider 112A is provided on the slide groove 112 and can slide along the slide groove 112; the seat support module 200 includes: a seat main frame 210 and a seat motor 220; the seat main frame 210 is slidably disposed on the slide rail 111; the seat motor 220 is disposed in the middle of the seat main frame 210; the seat motor 220 is drively connected to the slider 112A and is used to drive the slider 112A to slide toward the front end of the slide groove 112, so as to drive the seat main frame 210 to move along the front end of the slide rail 111.

[0042] When using it, please refer to Figure 2 and Figure 3 The slide rails 111 are located on both sides of the base frame 100; the slide groove 112 is located in the middle of the base frame 100; in actual use, the two sides of the seat frame 210 are slidably mounted on the slide rails 111, and the slider 112A is connected to the middle of the seat frame 210; at the same time, the seat motor 220 is located in the middle of the base frame 100 and is connected to the slider 112A for transmission. When the electric sofa is unfolded, the seat motor 220 drives the slider 112A to slide towards the front end of the slide groove 112, thereby driving the seat frame 210 to slide towards the front end of the slide rails 111.

[0043] Specifically, the slide rail 111 is V-shaped, with an obtuse angle and the V-shaped opening facing upwards. When slider 112A drives seat frame 210 to slide, the structural design of "V"-shaped slide rail 111 causes seat frame 210 to move diagonally upward toward base frame 100, thereby raising the height of footrest module 300. At the same time, one end of lumbar support module 400 is rotatably connected to seat frame 210, and the other end is rotatably connected to base frame 100. When the left main frame slides along "V"-shaped slide rail 111, it causes the end of lumbar support module 400 connected to seat frame 210 to rotate toward the rear end of base frame 100 (the end opposite to the sliding direction of seat frame 210), and the end of lumbar support module 400 connected to base frame 100 to rotate toward the front end of base frame 100 (the end with the same sliding direction as seat frame 210). Thus, the height of lumbar support module 400 gradually decreases as seat frame 210 slides, until the height of lumbar support module 400 is lower than footrest module 300, achieving zero gravity state for the sofa.

[0044] As can be seen, this application drives the slider 112A to slide through the seat motor 220, which in turn drives the seat frame 210 to slide on the "V"-shaped slide rail 111, thereby raising the height of the footrest module 300 until the height of the footrest module 300 is higher than the height of the lumbar support module 400. This achieves a zero-gravity sofa structure that is simple to implement and easy to operate.

[0045] In another embodiment of this utility model, please refer to Figure 2 and Figure 3 The footrest module 300 includes: a footrest module 300 and a footrest telescopic motor 320; a footrest main frame 310, one end of which is rotatably mounted on the seat main frame 210; the other end is movably mounted; the footrest telescopic motor 320, one end of which is connected to the footrest main frame 310 for transmission, and the other end of which is fixedly mounted on the seat main frame 210; when the footrest telescopic motor 320 extends, it drives the footrest main frame 310 to rotate until the position of the footrest module 300 is higher than the position of the lumbar support module 400.

[0046] Specifically, one end of the footrest main frame 310 is rotatably mounted at the front end of the seat main frame 210; one end of the footrest telescopic motor 320 is fixedly mounted on the seat main frame 210 away from the footrest main frame 310, and the other end of the footrest telescopic motor 320 is connected to the footrest main frame 310 for transmission. In actual use, the footrest telescopic motor 320 extends forward, driving the footrest main frame 310 to rotate, and the movable end of the footrest main frame 310 extends forward and gradually rises and unfolds. At the same time, the lumbar support module 400 gradually decreases in height as the seat main frame 210 slides, thereby raising the height of the footrest main frame 310. When the sofa frame is fully unfolded, the position of the footrest main frame 310 is higher than the position of the lumbar support, achieving a zero-gravity state for the sofa.

[0047] As can be seen, in this application, the seat main frame 210 drives the footrest main frame 310 and the lumbar support module 400 to move synchronously, so that the position of the footrest main frame 310 is higher than the height of the lumbar support module 400, which simplifies the operation process of the electric sofa to achieve zero gravity mode.

[0048] In this embodiment, please refer to Figure 1 and Figure 2 The lumbar support module 400 includes: a rotating part 410, a supporting part 420, a lumbar support plate, and a lumbar support motor; the rotating part 410 is rotatably mounted on the base frame 100 at one end and rotatably mounted on the seat main frame 210 at the other end; the supporting part 420 is mounted on the rotating part 410; the lumbar support plate is rotatably mounted on the supporting part 420; and the lumbar support motor is connected to the lumbar support plate and drives the lumbar support plate to rotate.

[0049] During use, as the sofa frame unfolds, the two ends of the rotating part 410 rotate in opposite directions: the end of the rotating part 410 connected to the base frame 100 rotates toward the front end of the base frame 100 (in the same direction as the sliding of the seat main frame 210), and the end of the rotating part 410 connected to the seat main frame 210 rotates toward the rear end of the base frame 100 (in the opposite direction to the sliding of the seat main frame 210). As a result, the position of the support part 420 gradually decreases, so that the position of the lumbar support module 400 is lower than the position of the footrest module 300.

[0050] Specifically, in actual use, the support part 420 is fixedly installed in the middle of the rotating part 410, and the two sides of the lumbar support plate (not shown in the attached drawing) are rotatably mounted on the support part 420. The support part 420 contains a lumbar support motor (not shown in the attached drawing), which is connected to the lumbar support plate. When the sofa frame is fully extended, the rotating part 410 rotates, causing the support part 420 to gradually lower until its position is lower than the footrest, achieving a zero-gravity state for the sofa. Simultaneously, based on different heights and weights, the lumbar support motor drives the lumbar support plate to rotate towards the footrest module 300, allowing it to rotate to an angle that conforms to the user's waist, improving comfort.

[0051] In this embodiment, the sliding distance of the seat main frame 210 along the slide rail 111 is 20-40 cm; the angle between the support part 420 and the base frame 100 is 10-30 degrees; and the angle between the footrest and the base frame 100 is 10-30 degrees. Specifically, the seat motor 220 controls the seat support to slide 30 cm on the slide rail 111; the footrest motor controls the footrest to rotate, so that the angle between the footrest and the base frame 100 is 20 degrees; and the lumbar support motor controls the support part 420 to rotate, so that the angle between the support part 420 and the base frame 100 is 25 degrees. At this point, a zero-gravity state can be achieved. In actual use, the sliding distance of the seat main frame 210, the angle of the footrest, and the angle of the support part 420 can be adjusted to meet the needs of people of different heights and body types.

[0052] In another embodiment of the present invention, the sofa frame further includes a headrest module; the headrest module (not shown in the drawings) includes a headrest component and a headrest motor; one end of the headrest component is fixedly mounted on the support portion 420, and the other end is movably mounted; the headrest component is connected to the headrest motor in a driving connection.

[0053] In use, one end of the head support is fixed to the support part 420 away from the rotating part 410, and the other end of the head support is movably disposed, and the movable end of the head support can be folded toward the fixed end; in actual use, a hinge is provided in the middle of the head support, and the head support motor is disposed in the support part 420 away from the rotating part 410, and the head support motor is connected to the movable end of the head support. When the head support motor is started, the head support motor drives the movable end of the head support to rotate toward the front end of the base frame 100, so that the head support is raised to better support the head.

[0054] Based on the above embodiments, this application also discloses a sofa, please refer to... Figure 2This includes any of the sofa frames described above. Specifically, when the sofa frame is fitted with the sofa cushion 500, the electric sofa is fully unfolded. The support part 420 is lowered in height under the drive of the rotating part 410, and the headrest gradually lowers as the support part 420 lowers, achieving a zero-gravity mode. At the same time, the support part 420 of the headrest and lumbar support module 400 is level with the rear end of the sofa cushion 500, that is, the headrest and support part 420 are just level with the end of the sofa against the wall, allowing the sofa to be placed against the wall without having to keep the sofa separated from the wall to accommodate the support part 420 and the headrest, thus reducing the space occupied by the sofa.

[0055] In summary, this invention discloses a sofa frame and a sofa, wherein the sofa frame includes a base frame, a seat support module, a footrest module, and a lumbar support module; the base frame is provided with a sliding groove assembly; the seat support module is slidably mounted on the sliding groove assembly; the footrest module is rotatably mounted on the front end of the seat support module; and the lumbar support module is rotatably mounted on the rear end of the seat support module. In this application, the seat support module slides on the sliding groove assembly, causing the footrest module and lumbar support module to rotate synchronously, so that the position of the footrest module is higher than the position of the lumbar support module, achieving a zero-gravity mode for the sofa. This solves the problems of complex structures and high costs associated with achieving a zero-gravity reclining posture in existing sofas.
