[0066] The present disclosure is further explained and illustrated below in conjunction with the accompanying drawings.

[0067] Exemplary embodiments are further described in detail hereafter with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms, and should not be understood as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure comprehensive and complete, and the concept of the exemplary embodiments can be fully conveyed to those skilled in the art. The same reference numerals in the drawings indicate the same or similar structures, and thus their detailed descriptions are omitted. In addition, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0068] Although relative terms such as upper and lower are used in this specification to describe the relative relationship between one component and another component of an icon, these terms are used in this specification only for convenience, for example, the direction of the example shown in the drawings. It can be understood that if a device of an icon is turned upside down, the described upper component will become the lower component. In the case that a structure is on an other structure, it may mean that the structure is integrally formed with the other structure, or that the structure is directly provided on the other structure, or that the structure is indirectly provided on the other structure via another structure.

[0069] The terms a, an, the, the, and at least one are intended to indicate the presence of one or more elements/components/and the like. The terms include and comprise are intended to be inclusive and mean that there may be additional elements/components/and the like other than the listed elements/components/and the like. The terms first, second, and the like are used merely as labels, and are not limiting on the number of their objects.

[0070] In the description of the present disclosure, it is to be noted that the terms center, up, down, left right, vertical, horizontal, inside, outside, etc. indicate an orientation, and the like indicate orientations or positional relationships based on those shown in the accompanying drawings, and are intended only to facilitate the description of the present disclosure and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated with a particular orientation, and therefore are not to be construed as a limitation of the present disclosure.

[0071] A detachable modular sofa, as shown in FIGS. 1-2, comprises a recliner 1 and a sofa 2, the recliner 1 and the sofa 2 being docked by means of a connecting member. As shown in FIGS. 3-4 and 14, the connecting member comprises a V-shaped slot 31 provided on the recliner 1 and a V-shaped plug 32 provided on the sofa. FIG. 14 clearly shows the specific shape configuration and specific location of the V-shaped plug, and since the assembly combination of the V-shaped slot 31 and the V-shaped plug 32 is prior art, it will not be described in detail hereafter. In addition, the V-shaped configuration of the slot and the plug in the drawings actually has a wide top and a narrow bottom, and is therefore named the V-shaped slot and the V-shaped plug.

[0072] The recliner is described below:

[0073] As shown in FIG. 5, the recliner 1 comprises a recliner backrest 11, a recliner side 12, a recliner bottom 13 and a recliner forepart 14, with a first bottom adjusting bracket 1A being mounted between the recliner bottom 13 and the recliner side 12. the recliner bottom 13 comprises a recliner bottom frame 13-1 and a number of recliner slats 13-2 mounted in parallel on the recliner bottom frame 13-1. The recliner slats 13-2 are mounted on the recliner bottom frame 13-1 by means of recliner plug-in fasteners 13-3, the recliner plug-in fasteners 13-3 comprises a first plug-in part 13-3-1 for securing to the attachment holes 33 on the recliner bottom frame 13-1 and a first socket part 13-3-2 for securing an end of each recliner slat 13-2.

[0074] As shown in FIGS. 6-7, the first bottom adjusting bracket 1A comprises: [0075] a first side fixing piece 1A1 for attaching the recliner side 12; [0076] a first straight support piece 1A2, hinged at one end to an end of the first side fixing piece 1A1 adjacent to the recliner backrest 11, and hinged at the other end to an end of the first bottom fixing piece 1A3 adjacent to the recliner backrest 11; [0077] a first bottom fixing piece 1A3 for attaching the recliner bottom 13; [0078] a first diagonal support piece 1A4, hinged at one end to an end of the first side fixing piece 1A1 near the recliner forepart 14, and hinged at the other end to an end of the first bottom fixing piece 1A3 near the recliner forepart 14.

[0079] Furthermore, the first diagonal support piece 1A4 has a greater length than the first straight support piece 1A2. Assuming that the articulation of the first side fixing piece 1A1 with the first diagonal support piece 1A4 is denoted as point A, and the articulation of the first bottom fixing piece 1A3 with the first straight support piece 1A2 is denoted as point B, then a reset spring 1A5 is also provided between the two points A and B.

[0080] The sofa is described below:

[0081] As shown in FIGS. 8-9, the sofa 2 comprises a sofa base comprising a sofa backrest 21, a sofa side 22 and a sofa bottom 23 and a lift assembly. The lift assembly comprises a lift base 25 and a lift bottom 26 provided on the lift base 25. A second bottom adjusting bracket 26A for lifting and lowering the lift bottom 26 is mounted between the lift base 25 and the lift bottom 26. A sofa forepart 24 is further included, the sofa forepart 24 is provided on a front end surface of the lift base 25.

[0082] As shown in FIG. 10, the lift bottom 26 comprises a lift bottom frame 26-1 and a number of sofa slats 26-2 provided in parallel on the lift bottom frame 26-1. The sofa slats 26-2 are further provided with a hook and loop Velcro 26-3 for easy attachment of sofa cushions. Each sofa slat 26-2 is mounted on the lift bottom frame 26-1 by means of a second plug-in fastener 26-4, the second plug-in fastener 26-4 comprises a second plug-in part 26-4-1 for securing to the attachment holes 33 in the lift bottom frame 26-1 and a second socket part 26-4-2 for securing an end part of the sofa slat 26-2.

[0083] As shown in FIGS. 11-13, the second bottom adjusting bracket 2A comprises a base fixing piece 2A1 for connecting the lift base 25 and a second bottom fixing piece 2A3 for connecting the lift bottom 26. The base fixing piece 2A1 and the second bottom fixing piece 2A3 are movably connected at their ends near the sofa backrest 21 by a linkage mechanism 2A2. The base fixing piece 2A1 and the second bottom fixing piece 2A3 are rotatably connected at their ends adjacent to the sofa forepart 24 by means of a second diagonal support piece 2A4; the second diagonal support piece 2A4 has a greater length than the linkage mechanism 2A2. The linkage mechanism 2A2 comprises a first rod 2A2-1 hinged at one end to the base fixing piece 2A1, a second rod 2A2-2 hinged at one end to the other end of the first rod 2A2-1 and a third rod 2A2-3. The second rod comprises a short rod 2A2-2-1 and a long rod 2A2-2-2 integrally connected to the short rod 2A2-2-1 at an angle of about 135. The third rod 2A2-3 is hinged at one end to an articulated joint of the short rod 2A2-2-1 and the long rod 2A2-2-2, and the other end is hinged at the base fixing piece 2A1. The base fixing piece 2A1 is provided with a limit block 2A1-1 that always restricts the first rod 2A2-1 below the highest surface of the base fixing piece 2A1.

[0084] As shown in FIGS. 11-13, when the articulation point of the first link 2A2-1 with the base fixing piece 2A1 is denoted as point C, the articulation point of the second link 2A2-2 with the first link 2A2-1 is denoted as point D, the articulation point of the third link 2A2-3 with the second link 2A2-2 is denoted as point E, and the articulation point of the third link 2A2-3 with the base fixing piece 2A1 is denoted as point F, the following relationships are satisfied: CF>CD, CF>DE, CF<CD+DE; CF>DE+DF; DE>CFCD, DE>EF, DE<CFCD+EF.

[0085] As can be seen, the second bottom adjusting bracket 2A has a complex structure, and the combination of the complex structure makes the lift assembly realize not only the adjustment of the height, but also the adjustment of the displacement in the fore-and-aft direction. The fore-and-aft direction mentioned refers to the direction parallel to the direction in which the user's thighs are facing when the user uses the above-described sofa in a seated upright position. Specifically, when the lift assembly is closed (folded), not only the height decreases, but also its fore-and-aft direction is displaced, so as to save occupied space for better placement under the sofa base. And when the lift assembly is fully opened (unfolded), as shown in FIG. 11, the lift bottom 26 rises to be substantially parallel to the bottom of the sofa base; and the lift bottom 26 is also simultaneously displaced in the fore-and-aft direction, such that the lift bottom 26, after being collocated with the bottom of the sofa base, can minimize the resulting gap.
