The two splicing slots 2 are effectively connected to the back plate 5 Or the minimum number of adjacent sofa seats 1, and the position of the splicing slot 2 close to the four corners can make the overall connection stability and firmness of the sofa seat 1 connected to the back panel 5 or the adjacent sofa seat 1 better.

The sofa module in this implementation example has the same splicing slot 2 on the top surface of the sofa seat 1 corresponding to each side. According to the objects that need to be connected on each side of the sofa seat 1, devices are inserted into the splicing slot 2. The first connecting piece used to connect the back panel 5 or the second connecting piece used to connect the sofa seat 1 makes the sofa seat 1 have modular properties, and the sofa can be customized. The sofa modules in this implementation example can be spliced into a multi-person assembled sofa, or a single sofa module can be used as a single sofa.

Furthermore, a seat cushion 4 is provided on the top surface of the sofa seat 1. The seat cushion 4 covers the first splicing piece 3A or the second splicing piece 3B, thereby preventing the user from directly contacting the second splicing piece 3A when sitting on the sofa seat 1. A splicing piece 3A or a second splicing piece 3B.

After the sofa modules in this embodiment are spliced into an assembled sofa, the back plate 5 serves as the sofa back or armrest of the organized sofa. Therefore, the area where the user sits on the seat cushion 4 usually does not cover the first splicing piece 3A. However, as a multi-person assembled sofa, the part where the seat cushion 4 covers the second splicing piece 3B is usually included in the user's sitting area. Although it is covered by the seat cushion 4, the second splicing piece 3B may still be covered. Have a certain impact on user comfort. Based on this, the two ends of the second connecting rod 35 are connected to the top ends of the second plug-in rod 33 and the third plug-in rod 34, thereby reducing the sharp edges caused by the top ends of the second plug-in rod 33/third plug-in rod 34. feel. For the first splicing piece 3A, when the user leans on the backrest, the force load of the first connecting rod 32 is greater, and the first connecting rod 32 can be connected to the shaft of the first plug-in rod 31, so that the first plug-in rod 31 can The rod 31 is longer than the second plug-in rod 33/the third plug-in rod 34, thereby having higher rigidity.

Furthermore, arc-shaped connecting transition sections 36 are provided between both ends of the second connecting rod 35 and the top ends of the second plug-in rod 33 and the third plug-in rod 34 to further reduce the second The sharpness of the connecting part between the connecting rod 35 and the second plug-in rod 33/third plug-in rod 34 improves the user's comfort.
