One is: sitting mode, that is, the driving mechanism does not work, and the sofa remains in its original state; °, the positions of the cushion frame and the seat back are not adjusted; the third is: any mode, that is, after the foldable leg rest is unfolded 60°, and then driven by the driving mechanism, the chair back, seat cushion frame and foldable leg rest The three are linked. In this mode, users can adjust them at will according to their own needs. And during the switching process of the above-mentioned various modes, the upper edge of the chair back can always be located in the same vertical plane, which can ensure that the sofa is never placed or installed against the wall.

As a preference: the cushion frame includes side support plates symmetrically arranged on both sides of the upper end of the base, and the side support plates are slidably installed on the base through slide rails. Adopting the above-mentioned structure facilitates installation and manufacture.

As a preference: the foldable leg rest includes a support frame, and the support frame is rotatably connected to the cushion frame through the flip assembly on both sides, and the flip assembly includes a first connecting rod and a second connecting rod whose ends are hinged on the support frame. connecting rod, and the third connecting rod and the fourth connecting rod whose ends are hinged on the side support plate, wherein the first connecting rod and the third connecting rod are hinged to each other in the middle, and the first connecting rod is connected to the The far end of the fourth connecting rod is hinged, and the second connecting rod is hinged with the far end of the third connecting rod at an end away from the support frame. With the above structure, the electric telescopic rod pushes the fourth connecting rod to move, so that the opening and closing of the foldable leg rest can be realized.

Preferably, a transverse rod is fixedly installed between the two symmetrical fourth connecting rods, and the drive mechanism pushes the turning assembly to move through the transverse rod. The above-mentioned structure is convenient for installation, and can effectively ensure that the driving structure drives the opening and closing of the foldable leg rest.

As a preference: the linkage assembly includes sequentially hinged fifth connecting rod, sixth connecting rod and seventh connecting rod, wherein the fifth connecting rod is hinged on the chair back at an end away from the sixth connecting rod, and the sixth connecting rod The middle part is rotatably connected to the side support plate through an adapter block, and the seventh connecting rod is hinged on the base at the end far away from the sixth connecting rod; An eighth connecting rod is arranged between them, and an arc-shaped groove is arranged on the linkage part. One end of the eighth connecting rod is provided with a guide column suitable for the arc-shaped groove, and the other end is rotatably connected to the fifth connecting rod. With the above structure, within the arc range of the arc groove, the driving mechanism can independently push the foldable leg rest to move in advance. The three folding leg rests are linked together.

As a preference: the lower end of the chair back is provided with a support rod, and the two ends of the support rod are rotatably mounted on the side support plate. The above-mentioned structure is adopted to facilitate installation.

As a preference: the support rod is fixedly mounted with a transfer portion extending radially outward, and the end of the fifth connecting rod away from the sixth connecting rod is hinged on the transfer portion. Adopting the above-mentioned structure can ensure that the driving mechanism pulls the above-mentioned chair back to rotate through the eighth connecting rod and the fifth connecting rod.

As a preference: the linkage component has a fan-shaped plate structure, and the central angle corresponding to the arc-shaped groove is 50-70°.

As a preference: the driving mechanism is an electric telescopic rod, one end of which is hinged on the base, and the other end is hinged on the middle of the horizontal rod. The above-mentioned structure is adopted to facilitate installation.

Compared with the prior art, the beneficial effects of the utility model are:

With the household electric functional sofa provided by the utility model, the sofa can be transformed into multiple modes for use, one is: sitting mode, that is, the driving mechanism does not work, and the sofa maintains the original state; the other is: comfortable mode, that is, the driving mechanism only drives The foldable leg rest is unfolded 60°, and the positions of the cushion frame and the seat back are not adjusted; the third is: any mode, that is, after the foldable leg rest is unfolded 60°, and then driven by the driving mechanism, the chair back, seat cushion The skeleton and the foldable leg rest are linked together. In this mode, users can adjust it at will according to their own needs. And during the switching process of the above-mentioned various modes, the upper edge of the chair back can always be located in the same vertical plane, which can ensure that the sofa is never placed or installed against the wall.
