[0015] In the description of the present application, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0016] Figure 1-2 To solve the above technical problems, as Figure 1-2As shown in the figure, the utility model designs a multifunctional folding sofa, including a support frame 1. A sofa cushion 2 is arranged on the support frame 1. A backrest 3 is arranged behind the sofa cushion 2. A groove is arranged at the bottom of the support frame 1. A linear drive mechanism 4 is arranged in the groove. The output end of the linear drive mechanism 4 is fixedly connected with a movable plate 5. Sliders 6 are symmetrically arranged on the left and right sides of the movable plate 5. Linear guide rails 7 which are slidably matched with the sliders 6 are arranged on the inner side of the groove of the support frame 1. A storage groove is arranged on the movable plate 5. A horizontally arranged rotating shaft 8 is arranged in front of the storage groove. One end of the rotating shaft 8 is connected with a rotary drive motor 9. Two support rods 10 are fixedly connected to the rotating shaft 8. The ends of the two support rods 10 are fixedly connected by a cross bar 11. The cross bar 11 is rotatably connected with a tray 12. When a tea table is needed, only need to make the linear drive mechanism 4 drive the movable plate 5 to move outwards, then drive the rotating shaft 8 to rotate through the rotary drive motor 9 to make the support rods 10 in a vertical state, and then adjust the tray 12 to a horizontal state. The design of the tray 12 not only serves as a part of the sofa, but also can act as a tea table, providing additional convenience for users without the need to purchase additional furniture. Through the design of the linear drive mechanism 4 and the movable plate 5 on the support frame 1, the sofa can flexibly adjust its shape and size to adapt to different space requirements, effectively saving living space.

[0017] Further, two hinge seats 13 are arranged at the bottom of the tray 12. One of the hinge seats is rotationally matched with the jack of the cross bar 11 through a smooth rod, and the other hinge seat 13 is matched with the threaded hole of the cross bar 11 through an adjusting bolt 14. When the tray 12 is needed, adjust it to a horizontal state. When the adjusting bolt 14 is screwed into the threaded hole on the side of the cross bar 11, the position of the tray 12 is fixed. When the tray 12 needs to be hidden, just screw out the adjusting bolt 14 to rotate the tray 12 to a suitable angle so that it fits on the movable plate 5 along with the support rod 10, providing a flexible adjustment function for the position of the tray 12, ensuring the stability of the tray 12 during use, and avoiding the inconvenience or danger caused by instability.

[0018] Further, two rollers 15 are symmetrically arranged on the left and right at the front side of the bottom of the movable plate 5. The rollers 15 are in contact with the ground, making it more convenient for the sofa to move when needed, reducing the friction and labor intensity during the moving process.

[0019] Further, the linear drive mechanism 4 is an electric push rod, realizing the automation of the sofa state adjustment, reducing the operation difficulty of users. The fast response characteristic of the electric push rod makes the unfolding and folding of the sofa faster, improving the use efficiency. Compared with other mechanical structures, the electric push rod is easier to maintain, reducing the cost and complexity of long-term maintenance.

[0020] Further, guard plates 16 are symmetrically arranged on the left and right sides of the support frame 1, which not only plays a protective role but also enhances the overall aesthetics of the sofa, enabling it to blend more harmoniously into the home environment.

[0021] Further, the backrest 3 is a foldable backrest 3. The foldable design allows users to adjust the angle of the backrest 3 according to personal needs, providing more comfortable support and adapting to different resting or sitting / lying positions. The structure of the backrest 3 is the same as that of a conventional adjustable-backrest sofa, and no further elaboration will be made in this utility model.
