[0016] Figure 4 for Figure 3 Schematic diagram of another orientation after removing the backrest panel on one side. DETAILED DESCRIPTION

[0017] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0018] like Figure 1-4As shown, an adjustable sofa comprises a sofa body 1, a plurality of legs 2 being fixedly mounted on the lower end of the sofa body; a vertically arranged upright board 3 being fixedly mounted upward from the middle of the sofa body, a horizontally arranged top board 4 being fixedly mounted on the upper end of the upright board, side boards 5 being fixedly mounted on both sides of the sofa body, and the side boards being fixedly connected to the upright board and the top board; a plurality of backrest boards 6 are arranged on both sides of the upright board, a partition board 7 is arranged between adjacent backrest boards, the partition board is fixedly connected to the upright board, a rotating shaft is rotatably mounted between the two side boards, the backrest board and the partition board are provided with through holes for rotating with the rotating shaft, and a backrest board angle adjustment structure 8 is mounted on the upright board opposite the backrest board.

[0019] The sofa body is a conventional structure, with the legs elevated to increase its height. The vertical panels divide the sofa into two positions, each with a number of backrest panels. The backrest angle adjustment mechanism adjusts the backrest angle to meet different backrest angle requirements, enhancing the sofa's practicality. Furthermore, the angle of each backrest panel can be adjusted individually for easy use.

[0020] Specifically, the two ends of the rotating shaft are connected to the side panels via bearings, and the side panels are fixed to the vertical and top panels of the sofa body via screws. The side panels block the area between the two backrest panels, preventing the backrest angle adjustment structure from being exposed and improving the overall integrity. The partition can support the rotating shaft and improve stability.

[0021] During implementation, the backrest angle adjustment structure includes a frame 9 fixedly mounted on the vertical plate, a reduction motor 10 fixedly mounted on the upper end of the frame, the output shaft of the reduction motor passes through the frame and is fixedly connected to the upper end of the screw 11, the lower end of the screw is connected to the frame through a bearing, an adjustment block 12 is slidingly fitted in the frame, a nut block is fixedly mounted on the adjustment block, and the nut block is threadedly connected to the screw, a slide groove 13 is provided on both sides of the frame, and sliding rods slidingly fitted with the slide grooves are fixedly mounted on both sides of the adjustment block, a rotating arm 14 is rotatably mounted on the sliding rod, and the end of the rotating arm away from the sliding rod is rotatably connected to a support 15, and the support is fixedly mounted on the backrest plate.

[0022] In this way, the reduction motor drives the screw to rotate, the screw cooperates with the nut block to drive the adjustment block to move, the adjustment block drives the slide bar to move in the vertical direction, and then drives the rotating arm to rotate, and the rotating arm drives the backrest board to rotate, thereby realizing the angle adjustment of the backrest board.

[0023] Specifically, an integrated control panel is fixedly mounted on the sofa body. The integrated control panel is provided with an interface for electrical connection to the reduction motor. Each backrest panel of the sofa body is provided with a control terminal electrically connected to the integrated control panel. The integrated control panel is externally connected to a power cord via a power supply circuit. The end of the power cord has a power plug. This is prior art and will not be further described.

[0024] During implementation, cushions 16 are placed on both sides of the sofa body, and the cushions are arranged opposite to the backrest board, so as to improve the comfort of the sofa.

[0025] During implementation, described sofa body is fixedly installed with baffle plate 17 between two seat cushions. Be convenient to separate seat cushions.

[0026] During implementation, a backrest pad 18 is fixedly installed on the backrest plate to improve the comfort of the sofa.

[0027] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention.
