[0005] Furthermore, a first connecting plate and a second connecting plate are provided on the first base plate, the first flip rod and the second flip rod are both hinged to the first connecting plate, and the support rod is hinged to the second connecting plate.

[0006] Furthermore, a third connecting plate is provided on the base bracket, and the first flip rod and the second flip rod are both hinged to the third connecting plate.

[0007] Furthermore, a cavity is provided on the side of the backrest bracket facing the base bracket, a second base plate is placed in the cavity, a flexible pad is provided on the second base plate, and the flexible pad on the backrest bracket is detachably connected to the opening of the cavity.

[0008] Furthermore, the second base plate is hinged to the base bracket.

[0009] Furthermore, blocks are provided on both sides of the flexible pad of the backrest bracket and on the side away from the first seat cushion plate, and slots corresponding to the blocks are provided on the inner wall of the cavity. The blocks extend into the slots and support the flexible pad through multiple slots.

[0010] Compared with the prior art, the beneficial effects of the utility model are: when the first base plate is located above the base support, it can be used as a conventional sofa; when the area on the base support needs to be increased, the first base plate can be lifted upward and moved in an arc to the side of the base support away from the backrest support, and then another flexible pad is placed on the base support, so that the area of ​​the sofa is doubled without sacrificing the backrest.

Therefore, the definition of "first" and "second" features can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" and "a number" is two or more, unless otherwise clearly and specifically defined.

[0019] Reference Figures 1 to 5 The utility model is further described.

[0020] A flip sofa comprises a base support 1 and a back support 2, wherein the base support 1 is provided with a first base plate 3, and the back support 2 and the first base plate 3 are both provided with flexible pads 4, and two pairs of flipping mechanisms are provided between the first base plate 3 and the base support 1, and the flipping mechanisms comprise a first flipping rod 5, a second flipping rod 6, a third flipping rod 7 and a support rod 8, wherein both ends of the first flipping rod 5 and the second flipping rod 6 are respectively hinged to the base support 1 and the first base plate 3, one end of the third flipping rod 7 is connected to the rotating shaft of the first base plate 3 hinged to the second flipping rod 6, and the other end is hinged to the support rod 8, and one end of the support rod 8 is hinged to the first base plate 3.

[0021] like Figures 1 to 5 As shown, when the first base plate 3 is located above the base support 1, it can be used as a conventional sofa; when the area on the base support 1 needs to be increased, the first base plate 3 can be lifted upward and moved in an arc to the side of the base support 1 away from the backrest support 2, and then another flexible pad 4 is placed on the base support 1, so that the area of ​​the sofa is doubled without sacrificing the backrest.

[0022] When flipping, the first flip rod 5 and the second flip rod 6 rotate, driving the first base plate 3 to rotate upward in an arc manner (parallel four-bar linkage principle) until the plane on which the flexible pad 4 is placed on the first base plate 3 is flush with the end face on the base bracket 1. When the first base plate 3 flips and moves, the rotating second flip rod 6 drives the third flip rod 7 to rotate, and then drives the support rod 8 to rotate on the first base plate 3. When the first base plate 3 is flipped over, the support rod 8 is vertically supported on the ground to support the first base plate 3. When the first base plate 3 is flipped and reset, the support rod 8 is synchronously retracted to the bottom of the first flip plate.

[0023] like Figure 2 As shown, in this embodiment, preferably, both the first flip rod 5 and the second flip rod 6 are V-shaped, which improves the supporting strength when the first base plate 3 is flipped.

[0024] like Figure 2As shown, in this embodiment, preferably, the first base plate 3 is provided with support plates around it, and the surrounding support plates enclose to form a turning cavity.

[0025] like Figure 2 As shown, in this example, preferably, the first base plate 3 is provided with a first connecting plate 9 and a second connecting plate 10, the first flip rod 5 and the second flip rod 6 are both hinged to the first connecting plate 9, and the support rod 8 is hinged to the second connecting plate 10.

[0026] like Figure 2 As shown, in this example, preferably, a third connecting plate 11 is provided on the base bracket 1 , and the first flip rod 5 and the second flip rod 6 are both hinged to the third connecting plate 11 .

[0027] like Figure 2 As shown, in this example, preferably, a cavity 12 is provided on the side of the backrest bracket 2 facing the base bracket 1, a second base plate 13 is placed in the cavity 12, a flexible pad 4 is provided on the second base plate 13, and the flexible pad 4 on the backrest bracket 2 is detachably connected to the opening of the cavity 12. When the first base plate 3 is flipped over, the flexible pad 4 on the backrest bracket 2 can be removed first, and then the second base plate 13 can be taken out of the cavity 12 and placed on the base bracket 1, and then the flexible pad 4 of the backrest bracket 2 can be reconnected to the backrest bracket 2 to facilitate the placement of the second base plate 13.

[0028] Preferably in this example, the second base plate 13 is hinged to the base bracket 1 , and the second base plate 13 can be directly taken out of the cavity 12 of the backrest bracket 2 by rotating.

[0029] like Figure 2 As shown, in this embodiment, preferably, the flexible pad 4 on the backrest bracket 2 is arranged obliquely.

[0030] like Figure 2 As shown, in this example, preferably, blocks 14 are provided on both sides of the flexible pad 4 of the backrest bracket 2 and on the side away from the first seat cushion plate, and a slot corresponding to the block 14 is provided on the inner wall of the opening of the cavity 12 (not shown in the drawings), and the block 14 extends into the slot and supports the flexible pad 4 through a plurality of slots. When the flexible pad 4 is pulled out, the block 14 is separated from the slot.
