Embodiment 1

[0041] Referring to FIG. 1 to FIG. 10, an assembly sofa, includes a sofa seat frame 1, a plurality of backrest plates 2, a plurality of seat plates 3, a plurality of front guard plates 4, two armrest boxes 5 and a plurality of cushions. Wherein, the sofa seat frame 1 is a structural frame of the assembly sofa, the backrest plates 2, the seat plates 3, the front guard plates 4 and the armrest boxes 5 are all assembled and connected to the sofa seat frame 1, so as to be assembled into a complete assembly sofa.

[0042] More specifically, the plurality of backrest plates 2 are transversely arranged side by side and connected to a rear side of the sofa seat frame 1 to form a complete sofa backrest, so as to support backs of users. The plurality of seat plates 3 are transversely arranged side by side and connected to a top of the sofa seat frame 1 to form a complete sofa seat. The plurality of front guard plates 4 are transversely arranged side by side and connected to a front side of the sofa seat frame 1 to form a complete front sofa guard plate. The two armrest boxes 5 are connected to two sides of the sofa seat frame 1 respectively so as to support arms of the users.

[0043] In the embodiment, the armrest boxes 5 are of box type structures, cavities a are formed inside the armrest boxes, openings communicated with the cavities a are formed in bottoms of the armrest boxes 5, and the armrest boxes 5 are specifically formed by splicing and assembling a plurality of plate bodies.

[0044] In the embodiment, the cushions are arranged on the backrest plates 2 or/and seat plates 3, usually, the cushions are arranged on the backrest plates 2 and the seat plates 3, that is, in the embodiment, the cushions include a plurality of backrest cushions 61 arranged on the backrest plates 2 and a plurality of seat cushions 62 arranged on the seat plates 3.

[0045] When the assembly sofa in the embodiment is packed, the cavity a inside one armrest box 5 is used for storing the plurality of stacked backrest plates 2, and the cavity a inside the other armrest box 5 is used for storing the vacuum-compressed cushions.

[0046] According to the assembly sofa in the embodiment, the armrest boxes 5, as structures for supporting the arms of the users, have certain widths to provide the users with a good supporting feeling, and an overall thickness of the plurality of stacked backrest plates 2 is matched with the widths of the armrest boxes 5. During packing, the stacked backrest plates 2 can be stored in the cavity a of one armrest box 5, and the plurality of cushions are firstly vacuum-compressed and then stored in the cavity a inside the other armrest box 5, so that the assembly sofa can be effectively compressed in the packing spaces, thereby improving the storage capacity of a container to reduce the logistics transportation costs.

[0047] It should be noted that compared with the prior art, a structure of the assembly sofa in the embodiment is not excessively disassembled, the packing spaces are narrowed on the premise of ensuring structural firmness of the assembled sofa and not adding production costs, thereby really reducing comprehensive costs.

[0048] More specifically, with regard to comfort experience of the users, the backrest cushions 61 have to sufficiently support the backs, especially waists and necks, of the users, thicknesses of the backrest cushions 61 are greater than those of the seat cushions 62 based on settings of ergonomics under a physiological curve conforming to natural bending of human spines, and usually, the thicknesses of the backrest cushions 61 are 1.5 to 3 times those of the seat cushions 62. Thus, in the embodiment, the cavities a of the armrest boxes 5 are used for storing the vacuum-compressed backrest cushions 61, so that the cavities a inside the armrest boxes 5 can be utilized to the maximum degree, and part of the seat cushions 62 can be stored after being vacuum-compressed if there are excess spaces of the cavities a. The vacuum-compressed backrest cushions 61 can be flat laid and stacked and then stored in the cavities a inside the armrest boxes 5, and can also be rolled into cylinders to be stored in the cavities a inside the armrest boxes 5.

[0049] In the embodiment, the sofa seat frame 1 is arranged into an assembly seat frame structure, has a plurality of components, and is provided with assembly parts 1a for assembling these components, so that a volume occupied by the sofa seat frame 1 during packing is packed can be reduced, thereby further narrowing the packing spaces.

[0050] With regard to the armrest boxes 5, in the embodiment, the armrest boxes 5 are provided with rear armrest box bodies 51 and front armrest box bodies 52, which are of integrated structures. Horizontal heights of tops of the rear armrest box bodies 51 are greater than those of tops of the front armrest box bodies 52, and bottoms of the rear armrest box bodies and front armrest box bodies are flush. Armrest portions 5a are formed on the tops of the rear armrest box bodies 51, so as to support the arms of the users, while the tops of the front armrest box bodies 52 are basically flush with the seat plates 3, so that seat plate extension portions 3a are formed on the tops of the front armrest box bodies 52. Correspondingly, convex portions 621 extending outwards are arranged on front sides of the seat cushions 62 arranged on the seat plates 3 on outermost sides, and the convex portions 621 cover the tops of the front armrest box bodies 52.

[0051] In the embodiment, two portions are formed in a space inside each armrest box 5, wherein, main cavities a1 are formed by portions, corresponding to the rear armrest box bodies 51, of the cavities a, auxiliary cavities a2 are formed by portions, corresponding to the front armrest box bodies 52, of the cavities a, and since the horizontal heights of the tops of the rear armrest box bodies 51 are greater than those of the tops of the front armrest box bodies 52, containing spaces of the main cavities a1 are obviously larger than those of the auxiliary cavities a2. Based on division of the main cavities a1 and the auxiliary cavities a2, the main cavities a1 of the two armrest bodies 5 are respectively used for storing the stacked backrest plates 2 and the vacuum-compressed cushions when the assembly sofa is packed, and at least one of the auxiliary cavities a2 of the two armrest boxes 5 is used for storing the assembly parts 1a for assembling the sofa seat frame 1. The assembly parts 1a can be put in boxes b, then the boxes b are stored in the auxiliary cavities a2, in addition, the boxes b can further be pasted on inner walls of the armrest boxes 5 with adhesive tape, so as to prevent the assembly parts 1a from falling out of the armrest boxes 5.

[0052] Based on structural compositions of the front armrest box bodies 52 and the rear armrest box bodies 51, the main cavities a1 with larger spaces are used for storing the backrest plates 2/backrest cushions 61, and the auxiliary cavities a2 with smaller spaces are used for storing the assembly parts la, so that storage of the cavities a can be optimized, the storage capacity is maximized, and meanwhile the packing spaces can be further narrowed.

[0053] In the embodiment, the backrest plates 2 include main plates 21 and bent plates 22, the bent plates 22 are formed by bending top edges of the main plates 21 outwards, the main plates 21 are connected to the rear side of the sofa seat frame 1, so as to support the waists and backs of the users, while the bent plates 22 support the necks of the users, and bending the bent plates 22 backwards conforms to ergonomics, making the users feel more comfortable. If the backrest plates 2 in the embodiment are packed in a way the same as the prior art, the backrest plates 2 are put in a packing box, the backrest plates cannot be flat laid and packed due to their bending structures, which not only will increase a space volume occupied by themselves, but also is not conducive to narrowing the packing spaces, and moreover, the backrest plates are prone to breakage at bent positions due to excessive borne force from compression. In the embodiment, the backrest plates 2 are stored in the cavities a of the armrest boxes 5, not only can the packing spaces be narrowed, but also the backrest plates 2 are protected by the armrest boxes 5, so as to avoid breakage at the bent positions since the backrest plates are extruded. More specifically, the main plate 21 of the backrest plate 2 on one outer side, among the plurality of stacked backrest plates 2, is attached to a corresponding inner wall of the armrest box 5, the top edge of the bent plate 22 of the backrest plate 2 on the other outer side abuts against a corresponding inner wall of the armrest box 5, and an unoccupied space a3 is formed between the main plate 21 of such backrest plate and the corresponding inner wall of the armrest box 5. Due to the bending arrangement of the backrest plates 2, the stacked backrest plates can make contact with the two opposite inner walls of the armrest boxes 5 respectively, so that the backrest plates 2 cannot swing in the cavities a, thereby preventing structural damage during logistics transportation.

[0054] Since the unoccupied spaces a3 exist in the armrest boxes 5 for storing the backrest plates 2, in order to further increase a utilization rate of the cavities a, in the embodiment, at least one vacuum-compressed seat cushion 62 is stored in the corresponding unoccupied space a3. Since the seat cushions 62 on two sides are provided with the convex portions 621, the seat cushion 62 in a middle without the convex portions 621 is preferably vacuum-compressed and then stored in the corresponding unoccupied space a3.

[0055] With regard to the sofa seat frame 1, in the embodiment, the sofa seat frame 1 includes a plurality of connected rear beam pipes 11, a plurality of connected front beam pipes 12, a plurality of supporting pipes 13 and a plurality of connecting pipes 14.

In addition, the front beam pipes 12, the rear beam pipes 11, the supporting pipes 13 and the connecting pipes 14 disassembled from the sofa seat frame 1 during packing are all of right pipe structures, so that spaces occupied by themselves can be narrowed to the maximum degree, thereby further narrowing the packing spaces.

[0056] In the embodiment, ends of two connected front beam pipes 12/rear beam pipes 11 and top ends of the supporting pipes 13 are connected by the assembly parts la, and two ends of the connecting pipes 14 and pipe bodies of front and rear symmetrically-aligned supporting pipes 13 are connected by the assembly parts la.

[0057] Furthermore, in the embodiment, the sofa seat frame 1 further includes a plurality of inserting pipes 16, the top end of each of the supporting pipes 13 is provided with two first assembly pieces 131 extending towards two sides and attached to bottoms of the two connected front beam pipes 12/rear beam pipes 11 respectively, two ends of one of the inserting pipes 16 are inserted into the ends of the two connected front beam pipes 12/rear beam pipes 11 respectively, and the assembly parts 1a penetrate through the first assembly pieces 131, the front beam pipes 12/rear beam pipes 11 and the inserting pipes 16. A rigid pipe body is formed by the plurality of connected front beam pipes 12 and rear beam pipes 11 by making the inserting pipes 16 inserted to the ends of the two connected front beam pipes 12/rear beam pipes 11, which can improve overall structural strength of the sofa seat frame 1, improve supporting strength for the seat plates 3, and meanwhile also improve connection firmness of the front beam pipes 12/rear beam pipes 11 and the supporting pipes 13.
