DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail in conjunction with the embodiments and drawings. Here, the illustrative embodiments of this application and their descriptions are used to explain this application, but are not intended to limit this application.

[0026] refer to Figures 1 to 6 ,like Figure 1 and Figure 2 As shown, this embodiment provides a support base for a functional sofa, including a base frame 1, a connecting rod group fixing frame 2, a driving connecting rod group 3 and a soft support seat 4, the driving connecting rod group 3 is connected between the connecting rod group fixing frame 2 and the base frame 1, and the soft support seat 4 can be detachably installed on the top surface of the connecting rod group fixing frame 2. The present application adopts modular installation. The overlapping arrangement of the soft bag support seat 4 and the connecting rod group fixing frame 2 can improve the supporting strength and make the seat body connected to the soft bag not easy to deform. When the soft bag support seat 4 connected to the soft bag needs to be replaced, it will not affect the installation of the driving connecting rod group 3, making the replacement of the soft bag support seat 4 simple and easy to operate. In addition, during production, the base frame 1, the connecting rod group fixing frame 2, and the soft bag support seat 4 can be produced and assembled separately. When assembling the sofa, multiple groups of modules can be quickly assembled to form a shape, which makes the assembly efficiency high. Since the connecting rod group fixing frame 2 and the soft bag support seat 4 are two independent and superimposed structures, the gap between the soft bag support seat 4 and the driving connecting rod group 3 is increased, and the deformation of the elastic member 44 of the soft bag support seat 4 and the interference with the driving connecting rod group 3 are avoided. The structural flexibility of the soft bag support seat 4 is higher and can improve the strength. When needed, the soft bag support seat 4 can be used in conjunction with a variety of connecting rod group fixing frames 2 of different specifications, reducing component specifications and improving component versatility. The specific structure of the driving connecting rod group 3 can refer to the driving mechanism of the functional sofa in the prior art.

[0027] like Figure 3As shown, the base frame 1 has two symmetrically arranged side frames 11, which are used to connect with the sofa armrests, and the connecting part of the sofa armrests is located on the inner side of the side frames 11. The top surface of the side frames 11 is concave, and the concave part is used to limit the sofa armrests so that the sofa armrests can be installed stably. The driving link group 3 is located between the two side frames 11 to partially hide the driving link group 3, making the sofa appearance beautiful and the operation of the driving link group 3 can be conveniently observed from the front and back sides. In addition, the exposed use of the metal side frames 11 can reduce the difficulty of the leather palpation process.

[0028] like Figure 4 and Figure 5 As shown, the side frame 11 includes a side panel 111 and an upper edge panel 112 and a lower edge panel 113 connected to the side panel 111. The upper edge panel 112 and the lower edge panel 113 are both located on the inner side of the side panel 111, making the appearance of the side frame 11 smoother and more beautiful. The upper edge panel 112 is curved and flush with the upper edge surface of the side panel 111.

[0029] In the present application, the front and rear ends of the side frame 11 are also provided with an end edge plate located on the inner side of the side panel 111. The end edge plate, the lower edge plate 113 and the side panel 111 are integrally formed by a stamping process. The connection between the end edge plate and the lower edge plate 113 is fixedly connected by an angle plate. The upper edge plate 112 can be integrally formed by a stamping process and then welded to the side frame 11; the upper edge plate 112 can also be welded into one piece by multiple sections of welding strips, and the spliced upper edge plate 112 is welded to the side frame 11; part of the structure of the upper edge plate 112 can also be integrally formed with the side panel 111 by a stamping process, and then welded to form a complete upper edge plate 112 by welding strips; the connection between the end edge plate and the upper edge plate 112 is fixedly connected by an angle plate, which makes the structural strength of the side frame 11 greater and improves the supporting stability of the base frame 1.

[0030] In this application, in order to improve the structural strength and bearing capacity of the side frame 11, a number of reinforcing pipes 114 are provided between the side panels 111, the upper edge panels 112 and the lower edge panels 113. The reinforcing pipes 114 are provided with anti-slip wire holes 115 for installing the connecting cross beams 12. The provision of the anti-slip wire holes 115 makes the connection of the connecting cross beams 12 convenient and reliable.

[0031] In this application, the side panel 111 is provided with a hinge hole 116 for installing the driving connecting rod group 3 and a rivet nut 117 for installing the sofa armrest. The setting of the rivet nut 117 makes the installation of the sofa armrest simple and stable, and the preset hinge hole 116 facilitates the quick installation of the driving connecting rod group 3.

[0032] The chassis 1 of the present application has a simple structure and uses less material while meeting the functional requirements, thereby saving manufacturing costs.

[0033] In the present application, two supporting feet 13 are provided on the connecting beam 12, and the supporting feet 13 are preferably adjustable feet to facilitate the leveling of the sofa so that the sofa can be placed stably.

[0034] In this application, if Figure 6 As shown, the soft bag support seat 4 includes two oppositely arranged horizontal frames 41 and two oppositely arranged vertical frames 42. The adjacent horizontal frames 41 and vertical frames 42 are detachably connected by corresponding connecting plates 43. The corresponding connecting plates 43 are detachably connected to the connecting rod assembly fixing frame 2 so that the soft bag support seat 4 can be detachably installed on the connecting rod assembly fixing frame 2. Since the soft bag support seat 4 does not need to be connected to the driving connecting rod assembly 3, the separate installation of the soft bag support seat 4 can adapt to soft bag support seats 4 of different specifications according to soft bags of different specifications. In addition, the separate setting of the soft bag support seat 4 can make the front and rear horizontal frames 41 and the left and right vertical frames 42 have the same structure. There is no need to distinguish between the front and rear positions during installation, and there is no need to distinguish between the left and right positions of the vertical frames 42 during installation, which reduces the number of parts and simplifies processing and installation.

[0035] Specifically, the connecting plate 43 can be fixedly connected to the horizontal frame 41 and the vertical frame 42 or spliced together using bolts. When spliced together, a welding nut 413 is provided on the horizontal frame 41 and / or the vertical frame 42 to improve the connection strength of the bolts. When the horizontal frame 41 and the vertical frame 42 are detachably connected to the connecting plate 43, the various components can be classified and stored, and can be quickly installed when used, reducing the storage space required for the soft bag support seat 4.

[0036] In the present application, the horizontal frame 41 includes a horizontal tube 411 made of rectangular tube material, and a plurality of hooks 412 are provided on the horizontal tube 411. The vertical frame 42 includes a vertical tube 421 made of rectangular tube material. A plurality of side U-shaped parts 422 with downward openings are installed on the outer surface of the vertical tube 421. The side U-shaped parts 422 are formed by cutting channel steel or punching metal plates. The top surface of the side U-shaped parts 422 is flush with the top surface of the vertical tube 421, which is used to increase the support area of the soft bag and extend the service life of the soft bag. The use of rectangular tube material makes the processing technology of the horizontal tube 411 and the vertical tube 421 simple and has good load-bearing effect. When in use, a clip strip needs to be sewn at the corresponding position of the sofa fabric to serve as the connecting part. When the sofa fabric is installed with leather, the clip strip clamps the side U-shaped parts 422 to achieve a fixed connection between the soft bag support seat 4 and the sofa fabric, making the leather installation process simple and convenient, easy to operate, and reducing the difficulty of disassembling the connecting part.

[0037] In this application, the horizontal tube 411 and the hook 412 are connected as one by welding or screws, and the longitudinal tube 421 and the side U-shaped part 422 are connected as one by welding or screws, so that the parts can be processed separately from each other, which makes the processing efficiency high and the manufacturing process simple.

[0038] In the present application, the elastic member 44 is preferably a serpentine spring.

[0039] In the present application, the connecting rod assembly fixing frame 2 can be made of wood, metal or hard plastic.

[0040] This application adopts modular production and then assembly, which makes the production efficiency and installation efficiency high.

[0041] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will appreciate that various modifications and variations of the present embodiment are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
