[0039] With the rapid development of e-commerce, more and more people are experiencing the convenience of online shopping. To capture a larger market share, most products have adopted online sales methods. Furniture such as sofas are an important part of daily life, so online sales of sofas are also very popular. People can buy sofas through online stores and pick them up at a designated address, which is very convenient. However, some online stores have certain requirements for goods transportation, especially for overseas shipping. For example, Amazon has specific standards for the size, weight, and packaging of delivered goods. Currently, one-piece sofas are large and heavy, making packaging cumbersome and transportation costs high, thus failing to meet the requirements of online delivery.

[0040] To meet the demands of online sales, merchants opted for modular sofa shipping. This technology involves disassembling the sofa into several individual tubular components, side panels, and back panels. These tubular components form the main frame, and each component—including the side panels and back panel—has numerous connectors. These connectors are strategically placed, resulting in a fragmented sofa design that reduces packaging volume for online delivery. However, this modular design results in a large number of parts with poor integration, increasing the complexity of packaging and assembly. This complicates packaging and transportation, slows down assembly, and reduces usability, ultimately impacting the user experience.

[0041] In view of this, embodiments of this application provide a sofa that is easy to assemble and disassemble. The upholstery is detachably connected to the main body of the sofa, and the armrest frame is detachably connected to the base frame. A first connecting part is located on the side of the armrest frame facing away from the base frame, and the backrest frame is detachably connected to the armrest frame via the first connecting part. That is, the sofa of this application, which is easy to assemble and disassemble, has a simple disassembly and assembly structure for its four parts: base, armrests, backrest, and upholstery. This simplifies packaging and assembly steps, thereby improving the packaging efficiency and assembly speed of the sofa.

[0042] The following will describe the scheme of this application in detail with reference to the accompanying drawings.

[0043] Please refer to the following: Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the sofa body of the sofa that is easy to assemble and disassemble according to this application. Figure 2 This is a structural diagram of the sofa base for easy assembly and disassembly as described in this application. Figure 3 This is a schematic diagram of the support legs of the sofa that is easy to assemble and disassemble according to this application. This application provides a sofa that is easy to assemble and disassemble, including a sofa body 1 and an upholstered assembly (not shown). The upholstered assembly is detachably connected to the sofa body 1, facilitating the packaging or cleaning of the upholstered assembly.

[0044] In some embodiments, the sofa body includes a base 11, armrests 12, and backrest 13. The base 11 includes a base frame portion 111 and first elastic support portions 112. Multiple first elastic support portions 112 are disposed in the hollow portion of the base frame portion 111, and all multiple first elastic support portions 112 are connected to the base frame portion 111. The first elastic support portions 112 and the base frame portion 111 work together to provide support and enhance the support force to meet the user's usage needs of the base 11.

[0045] The armrest 12 includes an armrest frame portion 121 and a first connecting portion 122. The first connecting portion 122 is disposed on the side of the armrest frame portion 121 away from the base frame portion 111. The backrest 13 includes a backrest frame portion 131. The armrest frame portion 121 is detachably connected to the base frame portion 111, and the backrest frame portion 131 is detachably connected to the first connecting portion 122.

[0046] The sofa disclosed in this application is easy to disassemble and assemble. The sofa body 1 is divided into three parts: base 11, armrests 12, and backrest 13. The base 11 includes a base frame 111, the armrests 12 include an armrest frame 121 and a first connecting part 122, and the backrest 13 includes a backrest frame 131. The sofa body 1 is detachable by means of a detachable connection between the armrest frame 121 and the base frame 111, and a detachable connection between the backrest frame 131 and the armrest frame 121 via the first connecting part 122. The disassembly and assembly structure is simple and clear, and the disassembly process is modular, thereby simplifying the packaging and assembly steps and improving the packaging efficiency and assembly speed of the sofa.

[0047] When the sofa needs to be packaged or stored, the upholstery components are first separated from the main sofa 1. The main sofa 1 is then disassembled into the base 11, armrests 12, and backrest 13, which facilitates stacking and storage, reduces packaging space, and thus lowers transportation costs.

[0048] Optionally, the base frame 111, armrest frame 121, and backrest frame 131 can all be made of iron. Iron frames are characterized by structural stability and resistance to deformation. Using iron frames for each frame part can provide high load-bearing capacity and good stability. In addition, iron frames are relatively lightweight, which not only makes them easy to transport but also facilitates independent assembly by users.

[0049] Optionally, the iron frame includes multiple square tubes that are spliced ​​together. The wall thickness of the square tubes in the base frame can be 2.0mm-2.2mm, for example, 2.00mm, 2.05mm, 2.10mm, 2.15mm, or 2.20mm. The wall thickness of the square tubes in the armrest frame 121 and the backrest frame 131 can be 1.2mm-1.5mm, for example, 1.20mm, 1.25mm, 1.30mm, 1.35mm, 1.40mm, 1.45mm, or 1.50mm. Since the base frame 111 bears most of the user's weight when the user uses the sofa, the wall thickness of the square tubes in the base frame 111 is thicker than that of other frame parts. The iron square tubes of each frame part within the above-mentioned wall thickness range meet the stability of the sofa body 1 and are relatively lightweight, which helps to reduce the transportation weight of the sofa.

[0050] Optionally, the detachable connection between the armrest frame 121 and the base frame 111, and the detachable connection between the backrest frame 131 and the first connecting part 122, includes a threaded connection or a pin connection. The upholstered components are detachably connected to the sofa body via zippers, Velcro, or fasteners. The aforementioned detachable connection structure is simple, reliable, and easy to disassemble and assemble.

[0051] In this embodiment, the hollow portion of the base frame portion 111 includes a first inner wall surface 1114 and a second inner wall surface 1115 along the width direction. The distance D1 between the first inner wall surface 1114 and the second inner wall surface 1115 is 570mm-600mm, that is, the inner space of the hollow portion of the base frame portion 111 along the width direction of the base frame portion 111 is 565mm-600mm, specifically 565mm, 570mm, 580mm, 590mm, and 600mm. The inner space of the hollow portion of the base frame portion 111 along the width direction of the base frame portion 111 within the above range meets the requirements for packaging and distribution, and also meets the minimum seat depth requirement of the sofa.

[0052] Optionally, a plurality of first elastic support portions 112 are arranged sequentially at intervals along the length direction of the base frame portion 111, and the distance between two adjacent first elastic support portions 112 is 100mm-130mm, for example, 100mm, 110mm, 120mm, 125mm, 130mm. The first elastic support portions 112 are evenly distributed in the hollow portion of the base frame portion 111, thereby providing uniform support force and improving the user experience.

[0053] Optionally, the first elastic support portion 112 may include, but is not limited to, arch springs, coil springs, etc., and the arch springs or coil springs may be detachably connected to the outer frame portion 1111 via, for example, spring mounting members (not shown). For example, the spring mounting members may be evenly arranged on both sides of the outer frame portion 1111 in the length direction, and the spring mounting members are provided with through holes for the two ends of the arch springs or coil springs to pass through.

[0054] It is understood that spring mounting components may include metal spring clips, plastic spring clips, or cord clips, etc. These spring mounting components have the advantages of low cost, small size, and high reliability, and can achieve a quick and reliable connection between the spring mounting component and the outer frame 1111.

[0055] Optionally, the base frame portion 111 includes an outer frame portion 1111 and a middle support portion 1112. The outer frame portion 1111 has a hollow portion, and the two ends of the middle support portion 1112 are respectively connected to the two sides of the outer frame portion along the width direction. The middle support portion 1112 includes a support round tube, a support square tube, and a support plate disposed on supporting the outer frame portion 1111, which effectively prevents the middle part of the outer frame portion 1111 from deforming and helps to improve the stability of the base frame portion 111.

[0056] Optionally, support feet 113 are provided at the corners of the outer frame 1111 and the middle support 1112. Figure 3 As shown in (a), support feet 113 are provided at the four corners of the outer frame 1111. These feet elevate the base 11, reducing the contact area between the base 11 and the ground, thus creating space between the base 11 and the ground for easier cleaning. Figure 3 As shown in (b), a support foot 113 is also provided on the intermediate support part 1112, so as to provide support for the intermediate support part 1112 and prevent the base frame part 111 from collapsing due to insufficient support in the middle.

[0057] Optionally, a first connector 114 is provided at the corner of the outer frame portion 1111. The first connector 114 is at least partially provided corresponding to the hollow portion of the outer frame portion 1111, and a plurality of first mounting holes 1141 are provided on the first connector 1141. The support foot 113 includes a second connector 1131 and a support foot 1132. A plurality of second mounting holes (not shown) are provided on the second connector 1131 corresponding to the first mounting holes 1141. The second mounting holes communicate with the first mounting holes 1141 for fasteners to pass through. The support foot 1132 is provided on the second connector 1131.

[0058] The support foot 113 is connected to the first connector 114 through the second connector 1131. The first connector 114 and the second connector 1131 are respectively provided with a plurality of first mounting holes 1141 and a plurality of second mounting holes. The first mounting holes 1141 and the second mounting holes correspond one-to-one. The support foot 113 can be quickly positioned through each mounting hole, effectively avoiding misalignment of the support foot 113 during installation.

[0059] Optionally, the first connector 114 may include, but is not limited to, steel plates, iron plates, etc., and the second connector 1131 may also include steel plates, iron plates, etc. Thus, multiple first mounting holes 1141 and second mounting holes are respectively provided on the first connector 114 and the second connector 1131, so that the first connector 114 and the second connector 1131 have multiple connection positions, which is beneficial to improving the connection reliability between the support foot 113 and the outer frame 1111.

[0060] Optionally, the fasteners may include, but are not limited to, screws, bolts, and other components. Using fasteners such as screws and bolts to connect the first connector 114 and the second connector 1131 can make the connection method of the first connector 114 and the second connector 1131 simple and reliable.

[0061] Optionally, the end of the support foot 1132 that is configured to support the ground is provided with a foot nail 1132a. The foot nail 1132a may include, but is not limited to, plastic sofa foot nails or rubber sofa foot nails, so as to have wear-resistant and anti-slip characteristics, which helps to protect the ground and further reduce the impact of noise.

[0062] like Figure 4 As shown, optionally, the armrest frame portion 121 is provided with a third mounting hole 1211, and the base frame portion is provided with a fourth mounting hole 1113 corresponding to the third mounting hole 1211. The fourth mounting hole 1113 communicates with the third mounting hole 1211. The fourth mounting hole 1113 and the third mounting hole 1211 are configured to allow fasteners to pass through, so that the armrest frame portion 121 is fixed to the base frame portion 111. The above connection structure is simple and can realize convenient disassembly and assembly. Moreover, the mounting holes used for connection are all set on the brackets connecting the two frame portions, so as to reduce the use of external connectors and save packaging space.

[0063] It is understood that the aforementioned fasteners include, but are not limited to, bolts, nuts, screws, and pins. These fasteners are used for fastening connections and have high convenience, safety, and reliability, enabling convenient and reliable connection of the various frame parts of the sofa.

[0064] In addition, the armrest 12 also includes a first flexible support (not shown). The first flexible support extends from one side of the armrest frame 121 to the other side of the armrest frame 121, so that the first flexible support is arranged in the hollow part of the armrest frame 121. The first flexible support may include elastic bands, nylon bands, etc. Thus, on the one hand, the first flexible support provides the necessary support for the hollow part of the armrest frame 121, which is beneficial to improving the comfort of the sofa; on the other hand, the use of the first flexible support not only simplifies the installation operation but also eliminates the need for additional installation accessories, thus simplifying the sofa installation process.

[0065] like Figure 4 and Figure 5 As shown, the backrest frame portion 131 has two fifth mounting holes 1311 on both sides along the width direction of the backrest frame portion 131, and the first connecting portion 122 has a sixth mounting hole 1221 corresponding to the fifth mounting holes 1311. The fifth mounting holes 1311 and the sixth mounting holes 1221 are configured to allow fasteners to pass through. The fifth mounting holes 1311 and the sixth mounting holes 1221 communicate with each other so that the backrest frame portion 131 is fixed to the first connecting portion 122.

[0066] Optionally, the first connecting part 122 is provided with a plurality of sixth mounting holes 1221. The fifth mounting hole 1311 of the backrest frame part 131 communicates with different sixth mounting holes 1221, and fasteners are used to pass through the fifth mounting hole 1311 and the sixth mounting hole 1221 to realize that the backrest frame part 131 is rotatably connected to the first connecting part 122, so that the user can select different tilt angles of the backrest frame part 131 to meet different user needs.

[0067] It is understood that the sixth mounting hole 1221 can be an elongated hole, and the sixth mounting hole 1221 can be an arc-shaped hole, so that the fastener can slide to different positions in the sixth mounting hole 1221 to adjust the rotation angle of the backrest frame relative to the first connecting part 122.

[0068] like Figure 5 As shown, optionally, the backrest 13 also includes a second elastic support portion (not shown) and a second flexible support portion (not shown). Considering that the support force required by the backrest frame portion 131 is less than that required by the base frame portion 111, and that the support strength required at the middle of the hollow portion of the backrest frame portion 131 along its length is greater than that at both ends, the backrest 13 of this application adopts the method of respectively setting the second elastic support portion and the second flexible support portion at the middle and both ends of the hollow portion of the backrest frame portion 131 along its length. This method can achieve support at the middle position of the backrest 13 while effectively reducing the cost of the sofa. It is understood that, as another example, the second elastic support portion and the second flexible support portion can also be alternately arranged along the length of the backrest frame portion 131.

[0069] It is understandable that the second elastic support includes arch springs, helical springs, etc., and the second flexible support includes elastic bands, nylon bands, etc.

[0070] Optionally, the soft-pack assembly may include a seat cushion, a backrest cushion, an armrest cushion, and a soft-pack cover. The seat cushion is detachably connected to the base frame portion 111, the backrest cushion is detachably connected to the backrest frame portion 131, and the armrest cushion is detachably connected to the armrest frame portion 121. The seat cushion, backrest cushion, and armrest cushion can be removed separately for easy cleaning or replacement.

[0071] Understandably, seat cushions, back cushions, and armrest cushions can all be vacuum-compressed during packaging to further reduce packaging space.

[0072] Optionally, the outer surfaces of the base frame 111, armrest frame 121, and backrest frame 131 are all covered with soft-padded covers, which protect each frame and reduce wear during use.

[0073] like Figure 6As shown, two armrests 12 are respectively connected to the two ends of the base frame 111 along the length direction. A second connecting part 124 is provided between the two armrests. The second connecting part 124 is located on one side of the base frame 111. The soft cover of the backrest frame 131 is provided with a back cover (not shown) on the side away from the base frame 111. The back cover extends downward to cover the second connecting part 124. The back cover is detachably connected to the second connecting part 124, which can better hide the structure and details of the bottom of the sofa and has the effect of dust and stain prevention.

[0074] It is understood that the second connecting part 124 can be, for example, an iron rod or a wooden block, so as to support and connect the back cover fabric, making it less likely to detach from the sofa.

[0075] The following is a brief description of the packaging process for the easily disassembled sofa of this application:

[0076] First, disassemble the sofa into a base 11, armrests 12, backrest 13, and upholstered components. Prepare a packaging carton and place the base 11 at the bottom. Then, place the upholstered outer cover from the upholstered components onto the base 11. Vacuum-compress the cushions, seat cushions, armrest pads, etc., and place them on the upholstered outer cover in sequence. Next, place the backrest 13 on top of the aforementioned cushions, seat cushions, and armrest pads, and finally place the armrests 12 on top of the backrest 13. This packaging method makes efficient use of the internal space of the packaging carton and prevents the sofa components from sliding inside the carton, thus improving the stability and efficiency of sofa packaging and transportation.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
