[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present application will be described more comprehensively with reference to the relevant drawings below. Some embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] refer to Figure 1 , combined with Fig. 9 , an embodiment of a sofa frame provided by the present application, the sofa frame includes a support frame 101 and a plurality of connectors 102, the support frame 101 is defined at the top with a first support area and a second support area surrounding the first support area, the first support area is used to support a seat cushion 12 of the sofa, the second support area is used to support one or more of a back cushion 10 or an armrest 11 of the sofa, the connector 102 includes a fixed end 103 and an insertion portion 104 arranged opposite to each other, the connector 102 is connected to the support frame 101 through the fixed end 103, so that the insertion portion 104 extends upward to the top of the second support area at a set height, and the insertion portion 104 can be inserted into the back cushion 10 or the armrest 11 of the sofa to connect the back cushion 10 or the armrest 11 to the second support area.

[0031] The sofa frame provides a very convenient installation basis, so that the staff or users can quickly assemble other components of the sofa, such as the cushion 10 or the armrest 11 .

[0032] refer to Fig. 9 It should be noted that, in order to realize assembly, the sofa assembly to be assembled needs to have a connection structure that cooperates with the plug-in connector 102. For example, the sofa assembly needs to have a notch 105 for the insertion portion 104 of the plug-in connector 102 to be inserted. The notch 105 is usually located at the bottom of the sofa assembly, and the interior of these sofa assemblies is provided with an inner cavity for accommodating the insertion portion 104. When assembling the sofa assembly, align the notch 105 at the bottom of the sofa assembly with the insertion portion 104 of the plug-in connector 102, and then push the sofa assembly downward to insert the sofa assembly into the insertion portion 104 until the bottom plane of the sofa assembly contacts the top surface of the sofa frame, and then the plug-in connector 102 is integrally inserted into its inner cavity, thereby completing the assembly of the sofa assembly. Correspondingly, when it is necessary to remove the assembled sofa assembly from the sofa frame, for example, for replacement, at this time, only the corresponding sofa assembly needs to be pushed upward to remove the sofa assembly.

[0033] In this way, whether it is assembled in a factory or at the user's place, the assembly efficiency can be greatly improved. At the same time, in the subsequent use stage, the user can replace the sofa components at any time to meet their personalized needs. In addition, when the sofa components are damaged or obsolete, only these parts need to be discarded, and the sofa frame can be used for a long time without causing adverse effects on the environment, effectively saving resources and being more environmentally friendly.

[0034] Different sofa components are different according to different needs and uses. For example, in some cases, the sofa may only need the cushion 10 but not the armrest 11. In this case, it is only necessary to set a corresponding connector 102 for connecting the cushion 10 on the rear side of the sofa frame. Figure 8 In this embodiment, a common sofa with both a back cushion 10 and an armrest 11 is taken as an example for explanation, wherein there is a pair of armrests 11, which are respectively located on the left and right sides of the sofa frame, and there are two back cushions 10. Therefore, the second supporting area for supporting the two back cushions 10 and the pair of armrests 11 is U-shaped.

[0035] refer to Figure 1 and Figure 2 , while combining Figure 8 In one or more embodiments, in order to more firmly position and connect the cushion 10 or the armrest 11, the connector 102 is an inverted U-shaped rod, and the two ends of the rod are fixed ends 103. In this way, when the connector 102 is connected to the support frame 101 through the two fixed ends 103, its U-shaped part as a whole is inserted into the corresponding notch 105 and inner cavity of the sofa component as an insertion end. By controlling the width of the U-shaped part, the overall width of the connector 102 can be matched with the size of the sofa component to be assembled, and it has sufficient rigidity and strength to resist deformation, which is more practical. Furthermore, the inverted U-shaped rod can be an integral rod, or it can be composed of several components, which is not limited here.

[0036] Of course, the connector 102 may also be in other forms as long as it can achieve the connection of the sofa assembly. For example, the connector 102 may be a columnar component that can cooperate with the hole set at the bottom of the sofa assembly to achieve the positioning and connection of the sofa assembly.

[0037] It should be noted that the number of the plug-in components 102 may be consistent with or inconsistent with the number of the sofa components to be assembled. For example, in one or more embodiments, the plug-in component 102 is a columnar plug-in column, and a sofa component is configured with multiple plug-in columns for connection.

[0038] In one or more embodiments, the connector 102 may also cooperate with a locking structure disposed thereon or an independent locking structure to lock the cushion 10 or armrest 11 inserted into place, for example, a buckle disposed on the connector 102 .

[0039] refer to Figure 1 and Figure 2 In one or more embodiments, the sofa frame further includes a connector 106, the number of which corresponds to the number of fixed ends 103, and the connector 106 is lockably slidably connected to the support frame 101, and the plug-in connector 102 is connected to the support frame 101 through the connector 106. In this way, on the one hand, it is convenient to realize the connection of the plug-in connector 102, and the position of the plug-in connector 102 can be adjusted according to actual needs to meet the personalized needs of the user. In particular, for the aforementioned inverted U-shaped rod, it is necessary to connect the two fixed ends 103 to the support frame 101, so there are certain requirements for the position accuracy of its fixed position, and the slidable connector 106 can facilitate the accurate positioning of the pair of fixed ends 103, so as to facilitate the accurate installation of the sofa assembly. In this way, when the sofa frame is installed, after the connector 106 is positioned to the correct position, the connector 106 is locked on the support frame 101 by operating, for example, a locking structure such as a screw, so that the connector 106 is fixed. If the position of the connector 106 needs to be adjusted, it is only necessary to open the locking structure.

[0040] refer to Figure 2 In one or more embodiments, the connector 106 includes a plug portion 107, and the fixed end 103 of the plug connector 102 includes a sleeve opening, and the plug portion 107 is nested and connected with the sleeve opening. In this way, the plug connector 102 can be inserted into the connector 106 in a manner similar to assembling the cushion 10 and the armrest 11, and can be very conveniently connected to the support frame 101. Furthermore, in order to prevent the plug connector 102 from falling off from the connector 106, the two can be fastened with fasteners such as screws.

[0041] It should be noted that the support frame 101 only needs to be used to form an area for placing and supporting the seat cushion 12, armrests 11, back cushion 10 and other components of the sofa, and its specific shape and structure are not particularly limited. Figure 1 and Figure 2In one or more embodiments, in order to facilitate manufacturing and reduce manufacturing costs, the support frame 101 includes four main beams 108 connected end to end in sequence, the first support area is rectangular, and the three main beams 108 located at the rear side and the left and right sides of the first support area are connected with connectors 102, wherein the connectors 102 connected to the left and right sides of the first support area are used to connect the armrests 11, and the connectors 102 connected to the rear side of the first support area are used to connect the cushions 10. In this way, for example, rib strips 109 (see FIG. 1 ) can be placed in the first support area formed between the main beams 108. Figure 8 ) and other components, the seat cushion 12 can be conveniently placed on the sofa frame of this embodiment.

[0042] Generally speaking, the height of the armrest 11 of the sofa is less than the height of the cushion 10. Therefore, in order to adapt to this situation, refer to Figure 1 , combined with Figure 8 In one or more other embodiments, the height of the inserting portion 104 of the connector 102 for connecting the armrest 11 is smaller than the height of the inserting portion 104 of the connector 102 for connecting the back cushion 10 .

[0043] refer to Figure 3 In one or more embodiments, in order to further reduce the manufacturing cost and facilitate the subsequent size adjustment, the main beam 108 is a profile, and the main beam 108 is provided with a first slide 110 along the length direction of the main beam 108 on the side facing the first support area, and also includes a connecting piece 106, the number of which corresponds to the number of the fixed ends 103, and the connecting piece 106 can be locked and slidably connected to the first slide 110. In this way, during production, the connecting piece 106 can be quickly installed on the main beam 108, and the factory can produce sofas of different sizes, such as different lengths and widths, by cutting the main beam 108, which can effectively reduce the design and manufacturing costs. At the same time, the user can also adjust the size of the sofa frame by cutting the main beam 108 to meet their actual needs. In addition, the first slide 110 is set on the side facing the first support area, which can effectively save space and facilitate the arrangement of the connecting piece. Of course, it can also be set at other positions of the main beam 108.

[0044] refer to Figure 2 , Figure 3 and Figure 5In this embodiment, the sofa frame also includes a connecting piece 106, the number of which corresponds to the number of the fixed ends 103, and the connecting piece 106 can be locked and slidably connected to the first slide groove 110. Specifically, the connecting piece 106 includes a connecting portion 111 arranged opposite to the plug portion 107, and the side surface of the connecting portion 111 has a first protrusion 126 that extends into the first slide groove 110 and is slidably connected to the inner wall of the first slide groove 110. In addition, the side surface of the connecting portion 111 also has a screw hole that runs through the entire connecting portion 111 and the first protrusion 126. A fastener such as a screw can lock the connecting piece 106 through the screw hole, and the position of the connecting piece 106 can be adjusted according to actual needs to meet the personalized needs of the user.

The support bar 112 is provided with a second protrusion 113 extending into the first slide groove 110. The second protrusion 113 is slidably connected to the inner wall of the first slide groove 110. The support bar 112 can be provided on two opposite main beams 108, so that the two ends of the rib bar 109 can be placed on the upper surface of the support bar 112 respectively, so as to facilitate the placement of the seat cushion 12. Since the support bar 112 is also a profile structure, it is easy to process and manufacture, and can also be connected and matched with the profile main beam 108. At the same time, since it can slide along the first slide groove 110, its position can be adjusted.

[0046] refer to Figure 6 In one or more embodiments, the cross-section of the support bar 112 is trapezoidal, and its cross-sectional area gradually increases on the side facing the main beam 108. Therefore, the support bar 112 has good bending strength, can better support the weight of the sofa cushion 12 and the person, and ensure the safety of the entire sofa frame structure.
