Modes for Carrying Out the Invention

[0014] In order for those skilled in the art to better understand the aspects related to the present invention, below, based on the drawings in the embodiments of this utility model, the technical solutions in the embodiments of the present invention will be clearly and fully described. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative labor all belong to the protection scope of the present invention.

[0015] Referring to FIGS. 1 to 3, an embodiment of the present invention discloses a zero-wall sofa that can be made flat, including a first frame 1 for constructing the backrest of the sofa, a second frame 2 for constructing the seat surface of the sofa, a backrest support holder 3, a connecting part 4, a motor 5, and a linear guide rail 6. The linear guide rail 6 is horizontally arranged, and a slider 61 is mounted thereon. The slider 61 slides on the linear guide rail 6. The motor 5 is fixed to the first end of the first frame 1, and the output end of the motor 5 is connected to one end of the linear guide rail 6 to drive the slider 61 to slide. The slider 61 is fixedly connected to the second frame 2 via the connecting component 4. The backrest support holder 3 is mounted on the first frame 1. The backrest support holder 3 is for supporting the backrest of the sofa to achieve a zero-wall.

[0016] A screw may be provided on the guide rail, and the motor 5 rotationally drives the screw, and the slider 61 slides by the rotation of the screw. This is a conventional linear guide rail 6, and detailed description is omitted here.

When unfolding, as the first frame 1 moves relative to the second frame 2, the hinged connection part between the first support lever 31 and the second support lever 32 gradually moves downward in accordance with the movement of the backrest of the sofa becoming flat.

[0021] In another selectable embodiment, it further includes an electric telescopic rod 8 and a foot support structure 9. The foot support structure 9 includes two link structures symmetrically arranged on the left and right sides of the second frame 2. The bottoms of the two link structures are fixed to the second frame 2, and a connecting lever is provided between the two link structures. Both ends of the connecting lever are fixed to the links of one link structure respectively. The fixed end of the electric telescopic rod 8 is provided on the second frame 2, and the extending end of the electric telescopic rod 8 is fixed to the connecting lever.

[0022] The electric telescopic rod 8 may include a motor 81 and a telescopic rod 82, and the telescopic rod 82 is driven by the motor 81 to change its length.

[0023] In another alternative embodiment, it further includes a first support part 10. The first frame 1 further includes a second connection lever 13. The second connection lever 13 is provided at the middle part between two fixed levers 12 and is for connecting the two fixed levers 12.
