Description

Technical Field

[0001] This application relates to the field of furniture, and more particularly to a sofa and a modular sofa. Background Technology

[0002] As people's living standards improve, their demands for the comfort of home furnishing products are increasing. Sofas with massage functions are becoming increasingly popular among consumers because they provide a comfortable rest and massage experience. One of the core components of a massage sofa is the massage airbag assembly integrated into the sofa's foam. The massage airbag achieves its massage function by inflating and deflating air.

[0003] In existing technologies, a common method is to directly sew the base fabric supporting the massage airbags onto the surface of the sponge or the cover fabric. While this method provides a strong connection, it is cumbersome, has low production efficiency, and is not conducive to automated production. Furthermore, subsequent repairs and replacements are difficult, requiring the disassembly of the entire sofa cover, resulting in poor maintainability. Another method involves adhesively gluing the massage airbag components to the sponge over a large area. This increases installation speed, but precise positioning during gluing is difficult, leading to misalignment and affecting the accuracy of the massage position.

[0004] Therefore, it is necessary to provide an improved sofa and modular sofa to solve the above problems. Utility Model Content

[0028] See Figures 1 to 3As shown, this application provides a sofa, including: a sofa sponge 100, a massage airbag assembly 200, and a fixing plate 300. The fixing plate 300 is fixed to the sofa sponge 100. The massage airbag assembly 200 is detachably assembled to the sofa sponge 100 via the fixing plate 300. This application connects the massage airbag assembly 200 to the sofa sponge 100 through the fixing plate 300 as an intermediate component, realizing the rapid installation of the massage airbag assembly 200 and improving production efficiency.

[0029] According to the embodiments of this application, the fixing piece 300 is bonded to the sofa sponge 100, and the fixing piece 300 is a non-elastic fabric. Specifically, the fixing piece 300 is made of non-woven fabric, and the shape and size of the non-woven fabric are fixed and it does not stretch or contract, ensuring that its shape and size are stable after fixing. It can provide a rigid fixing groove for the massage air bag assembly 200, effectively preventing the massage air bag assembly 200 from shifting or shaking during use, and ensuring the accuracy of the massage position.

[0030] According to other embodiments of this application, the fixing piece 300 may also be made of woven or knitted fabric, such as canvas or nylon, to improve its strength and abrasion resistance. Alternatively, the fixing piece 300 may also be made of flexible plastic sheet, such as PE or PVC.

[0031] The sofa foam 100 includes a seat foam 101 and a backrest foam 102. The backrest foam 102 is located on the rear side above the seat foam 101. In embodiments of this application, a massage airbag assembly 200 is assembled onto the seat foam 101 and the backrest foam 102. Alternatively, the massage airbag assembly 200 can be assembled separately onto the seat foam 101 or separately onto the backrest foam 102.

[0032] According to other embodiments of this application, the sofa foam 100 also includes headrest foam and hand foam. The headrest foam is disposed above the backrest foam 102, and the hand foam is disposed on one side of the seat foam 101 and the backrest foam 102. The massage airbag assembly 200 can be assembled onto the headrest foam and the hand foam. In addition, the massage airbag assembly 200 can be assembled separately onto the headrest foam or separately onto the hand foam. The massage airbag assembly 200 of this application is modularized and can be flexibly configured in different parts of the sofa, such as the seat foam 101, the backrest foam 102, the headrest foam, and the hand foam, thereby improving the flexibility of sofa assembly and production efficiency.

[0033] The massage airbag assembly 200 includes a back felt 10, a massage airbag 20, and a wiring harness assembly 30. The back felt 10 is installed between the sofa foam 100 and the fixing plate 300; specifically, the back felt 10 is fitted inside the fixing plate 300. The massage airbag 20 is fixed to the back felt 10 by laser welding. The wiring harness assembly 30 is connected to the massage airbag 20 and is used to inflate the massage airbag 20.

[0034] According to other embodiments of this application, the massage air bag 20 can also be fixed to the back felt 10 by means of adhesive bonding or mechanical fixation. Alternatively, other welding processes capable of achieving a strong connection, such as ultrasonic welding or high-frequency heat sealing, can also be used.

[0035] The fixing plate 300 has an opening 301, through which the backing felt 10 extends into the fixing plate 300. According to an embodiment of this application, the opening 301 faces the backing felt 10, and the backing felt 10 is detachably assembled with the fixing plate 300. The backing felt 10 is a structural substrate. The massage airbag 20 and the wiring harness assembly 30 are both integrated onto this substrate, forming the massage airbag assembly 200. During installation, assembly is completed simply by inserting the backing felt 10 into the fixing plate 300, achieving detachability of the massage airbag assembly 200, facilitating later maintenance and replacement, and solving the maintenance difficulties of traditional fixing methods such as overall gluing and sewing.

[0036] The fixing piece 300 is not limited to a bag shape; it can also be configured as an "H"-shaped or "I"-shaped clip structure, with its two free ends forming a clamping space to hold the backing felt 10 within the clamping space. Furthermore, the fixing method between the fixing piece 300 and the sofa sponge 100 is not limited to adhesive bonding; it can also be sewn or fixed using plastic clips, etc.

[0037] See Figures 4 to 6 As shown, the backing felt 10 has a non-centrally symmetrical structure. This non-centrally symmetrical structure ensures that the backing felt 10 has only one correct installation direction, preventing it from being installed backwards or incorrectly, thus achieving quick and convenient installation. The backing felt 10 includes several corners 11, which extend from the opening 301 between the sofa sponge 100 and the fixing piece 300. In the embodiments of this application, the backing felt 10 has four corners; specifically, the backing felt 10 has a quadrilateral structure. According to other embodiments of this application, the backing felt 10 itself can be rectangular, i.e., centrally symmetrical, but the error-proofing function is achieved by setting error-proofing marks such as notches and color markings.

[0038] See Figure 7 and Figure 8 As shown in the embodiment of this application, the backing felt 10 is trapezoidal. The backing felt 10 includes a first side 12, a second side 13, a third side 14, and a fourth side 15. The first side 12 and the second side 13 are arranged opposite each other and are parallel to each other. The third side 14 and the fourth side 15 connect the first side 12 and the second side 13. The first side 12, the second side 13, the third side 14, and the fourth side 15 together form four corners 11.

[0039] Furthermore, the backing felt 10 can be trapezoidal, or other irregular polygons. The number of corners 11 is not limited to four; two or more fixing points can achieve a stable fixing effect. In the embodiments of this application, the length of the second side 13 is greater than the length of the first side 12 to prevent errors and avoid incorrect installation orientation of the backing felt 10. Alternatively, error-proofing can also be achieved by setting error-proof markings or holes on the backing felt 10.

[0040] According to an embodiment of this application, the backrest felt 10 includes a seat cushion felt 16, a backrest felt 17, and a headrest felt 18. The seat cushion felt 16 is assembled to the seat sponge 101 via a fixing piece 300. The backrest felt 17 is assembled to the backrest sponge 102 via a fixing piece 300. The headrest felt 18 is assembled to the headrest sponge via a fixing piece 300.

[0041] The massage airbags 20 include a seat cushion airbag 201, a backrest airbag 202, and a headrest airbag 203. The seat cushion airbag 201 is fixed to the seat cushion felt 16 by laser welding. There are four seat cushion airbags 201, distributed on the seat cushion felt 16 and positioned near the four corners 11 of the seat cushion felt 16. The backrest airbag 202 is fixed to the backrest felt 17 by laser welding. There are four backrest airbags 202, distributed on the backrest felt 17 and positioned near the four corners 11 of the backrest felt 17. The headrest airbags 203 are fixed to the headrest felt 18 by laser welding. There are two headrest airbags 203, arranged side-by-side on the headrest felt 18 and near the center of the headrest felt 18.

[0042] According to the embodiments of this application, the number, size and layout of the massage air bags 20 can be adjusted according to the needs of the massage area. For example, the backrest air bag 202 can be an array of 6 or 8 air bags to achieve wave massage, and the seat cushion air bag 201 can be an array of air bags of different sizes.

[0043] The sofa foam 100 has a wire harness avoidance channel (not shown) for the wire harness assembly 30 to pass through. The wire harness assembly 30 includes an inflatable wire harness 31 and an electrical wire harness 32. Both the inflatable wire harness 31 and the electrical wire harness 32 are connected to the massage airbag assembly 200 and are located within the wire harness avoidance channel. This prevents the wire harness assembly 30 from scattering, avoids compression and wear, improves product safety and reliability, and makes the internal structure neater. The wire harness assembly 30 also includes an inflation module 33 connected to the inflatable wire harness 31 and a power supply module 34 connected to the electrical wire harness 32.

[0044] According to the embodiments of this application, the wire harness avoidance channel can be a hole opened on the foam body of the sofa foam 100, or it can be a plastic tube pre-embedded inside the sofa foam 100. In addition, wire harness fixing buckles or cable ties can be provided in the wire harness avoidance channel to further prevent the movement of the inflatable wire harness 31 and the electrical wire harness 32.

[0045] See Figures 2 to 4 As shown, according to an embodiment of this application, the fixing piece 300 is triangular in shape and includes a first adhesive edge 302, a second adhesive edge 303, and a connecting edge 304 connected in sequence. The first adhesive edge 302 and the second adhesive edge 303 are bonded and fixed to the sofa sponge 100 with water-based adhesive. An opening 301 is provided on the connecting edge 304. Specifically, the connecting edge 304 is not bonded to the sofa sponge 100 to form the opening 301.

[0046] The four corners 11 of the backing felt 10 correspond one-to-one with the four fixing pieces 300. The first adhesive edge 302 and the second adhesive edge 303 form an angle 305. In the embodiments of this application, the angle 305 is the same as the angle of the corner 11.

[0047] According to other embodiments of this application, the fixing piece 300 may also be rectangular, trapezoidal, semi-circular or other polygonal, as long as an opening 301 is provided on the side facing the back felt 10 to accommodate and restrict the corners 11 of the back felt 10.

[0048] The fixing piece 300 has a first adhesive surface on the side facing the backing felt 10, and the backing felt 10 has a second adhesive surface on the side facing the fixing piece 300. The first adhesive surface and the second adhesive surface are attached to each other and abut against each other to fix the backing felt 10 and the fixing piece 300. The first adhesive surface and the second adhesive surface are respectively the hook surface of the Velcro and the felt surface.

[0049] This application also provides a modular sofa, including the sofa as described above, wherein the number of sofas is greater than or equal to two. In an embodiment of this application, the number of sofas is three.

[0050] This application assembles the massage airbag assembly 200 onto the sofa sponge 100 by placing the back felt 10 between the sofa sponge 100 and the fixing plate 300. This simplifies the installation process and improves production efficiency. Simultaneously, since the fixing plate 300 is pre-fixed to the sofa sponge 100, inserting the back felt 10 into the fixing plate 300 confines the massage airbag 20 to a preset area, ensuring accurate positioning and improving product quality.

[0051] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
