Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of multifunctional furniture, in particular to a multifunctional sofa. Background Art
[0002] Multifunctional sofas include auxiliary functions such as massage, calf support, and seat extension, which can be used as a bed. Currently, sofas with seat extension functions are also equipped with extension pads inside the sofa. To convert the sofa into a bed, the user must first remove the restraints on the sofa, then manually pull the seat cushion along the sofa base. The extension pad is then removed and placed in the gap created by the seat cushion being moved, allowing it to connect with the seat cushion to extend the seat.
[0003] The process of manually changing the sofa into a bed is time-consuming and laborious. Moreover, when restoring the sofa to its original state after being transformed into a bed, the extension cushion needs to be removed and the seat cushion needs to be pushed back to its original position. This makes the multifunctional sofa inconvenient to use. Utility Model Content
[0004] In view of the deficiencies of the prior art, the present invention provides a multifunctional sofa, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] Reference Figure 1A multifunctional sofa comprises a base 1 and a support plate 2, the support plate 2 is fixedly connected to one end of the base 1, the support plate 2 is arranged in the vertical direction, the upper end of the support plate 2 is connected with a cushion 21, the cushion 21 is arc-shaped, one end of the cushion 21 is fixedly connected to the support plate 2, and the other end is bent downward, a receiving groove 22 is formed between the cushion 21 and the support plate 2, an extension pad 13 is arranged in the receiving groove 22, and when the extension pad 13 is placed in the receiving groove 22, the width direction of the extension pad 13 is arranged in the vertical direction; there is a gap between the cushion 21 and the base 1, and a seat cushion 12 is arranged on the base 1, and one end of the seat cushion 12 is located between the cushion 21 and the base 1.
[0017] Reference Figure 1 and Figure 2 The base 1 is provided with a mounting groove 11, the mounting groove 11 is provided with a driving assembly 3, the driving assembly 3 includes a driving member 31, a screw 32 and a connecting frame 33,
[0018] One side of the connecting frame 33 is connected to the bottom wall of the seat cushion 12, and the other side of the connecting frame 33 is threadedly connected to the screw 32. One end of the screw 32 is fixedly connected to the driving shaft of the driving member 31, and the other end passes through the connecting frame 33; the inner wall of the mounting groove 11 is connected to the mounting frame 111, and the connecting frame 33 is slidably connected to the mounting frame 111. The end of the screw 32 away from the driving member 31 is rotatably connected to the mounting frame 111, and the driving member 31 is connected to the inner wall of the mounting frame 111, and the driving member 31 is a motor.
[0019] Reference Figure 2 An adjustment component 4 is provided on one side of the cushion 21, and a connecting groove 211 is provided on the inner wall of the cushion 21, and one end of the connecting groove 211 is also provided on the side wall of the support plate 2; the adjustment component 4 includes a matching rod 41 and a matching piece 42, the matching rod 41 and the connecting frame 33 can be fixedly connected through a long rod, the matching rod 41 and the driving member 31 are staggered, the matching piece 42 is U-shaped, one end of the matching piece 42 is rotatably connected to the inner wall of the connecting groove 211, and the other end of the matching piece 42 is rotatably connected to the upper side of the extension pad 13, and the matching rod 41 is rotatably connected to the lower side of the extension pad 13.
[0020] When the multifunctional sofa is in use, the driving member 31 starts to drive the screw rod 32 to rotate, and the screw 32 rotates to drive the connecting frame 33 to move away from the support plate 2, and the connection frame 33 moves to drive the seat cushion 12 to move synchronously; when the connection frame 33 moves, the matching rod 41 is pulled to move synchronously. Since the matching rod 41 is fixedly connected to the connecting frame 33, the movement of the matching rod 41 is translational. During the movement of the matching rod 41, the lower side of the extension cushion 13 is pulled, causing the extension cushion 13 to move synchronously and start to rotate.
