Then, magnetic moments in different directions are sequentially applied to the second supporting legs 32, so that the second supporting legs 32 turn 90 degrees clockwise around the direction parallel to the x axis by taking the edge of the second surface 12, which is far away from the ground 300, as the center, so that the second supporting legs 32 are attached to the second surface 12, and then the second supporting legs 32 turn 90 degrees clockwise around the direction parallel to the z axis by taking the edge of the second surface 12, which is close to the second mounting portion 122, as the center, so that the second supporting legs 32 are perpendicular to the second surface 12, at this time, the second supporting legs 32 at least partially extend into the second mounting portion 122 under the magnetic force of the third magnetic element, so that the assembly and the connection of the second supporting legs 32 are realized, and the support of the seat cushion 10 can be realized.

Secondly, a magnetic moment is applied to the seat cushion 10, so that the seat cushion 10 is turned 90 ° clockwise around the direction parallel to the x-axis with the edge of the second surface 12 close to the ground 300 as the center, so that the second surface 12 of the seat cushion 10 faces the ground 300, and at this time, the seat cushion 10 is attached to the back cushion 20 under the magnetic force of the second magnetic element of the back cushion 20, so as to realize the assembly connection of the seat cushion 10 and the back cushion 20. And then, applying a magnetic moment to the fourth supporting leg 34, so that the fourth supporting leg 34 turns clockwise by 90 ° around the direction parallel to the x axis around the edge of the connecting surface 23 of the third surface 21 and the fourth surface 22, which is far away from the first wall surface 201, as a center, and at this time, the fourth supporting leg 34 at least partially extends into the fourth mounting portion 232 under the magnetic force action of the third magnetic element, so as to realize the assembly connection of the fourth supporting leg 34.

Finally, the third supporting leg 33 is separated from the wall surface 200 by a human force, and the third supporting leg 33 at least partially extends into the third mounting portion 231 to achieve the assembly connection of the third supporting leg 33, thereby achieving the support of the back cushion 20 and completing the assembly of the sofa 100.

Thus, the sofa 100 can be switched from the disassembly state to the use state under the action of current, so that the semi-automatic assembly of the sofa 100 is realized, and the assembly of the sofa 100 is simpler, more convenient and quicker.

When the sofa 100 is switched from the use state to the disassembly state, the sofa 100 can be disassembled manually with the current cut off, or the sofa 100 can be disassembled semi-automatically by using the control circuit, and the process will not be repeated here.

In some embodiments, when the sofa 100 is in the disassembled state, the seat cushion 10 and the back cushion 20 have a first distance h1 with respect to the ground 300, the length of the supporting legs 30 is h2, and h1 is greater than or equal to h2.

Like this, can reduce the removal to cushion 10 and back cushion 20 to simplify the operating procedure, simultaneously, can be favorable to the equipment of supporting legs 30, avoid leading to the condition of operation difficulty or emergence interference when semi-automatic equipment because of the size mismatch, thereby can improve user's use and experience the sense.

Further, the length or width of the seat cushion 10 is a, the length of the opening of the first mounting portion 121 and the second mounting portion 122 is b, and a is greater than or equal to b + h2.

Thus, the supporting legs 30 can be assembled at most twice during semi-automatic assembly, and the situation that multiple times of adjustment are needed due to size mismatching is avoided.

In some embodiments, as can be seen from the foregoing, the first mounting portion 121, the second mounting portion 122, the third mounting portion 231, and the fourth mounting portion 232 are all grooves, and the supporting foot 30 is a cylinder, so that the cross-sectional area of the supporting foot 30 along the height direction thereof is respectively smaller than or equal to the opening size of the corresponding mounting portion.

Thereby, the supporting legs 30 are at least partially inserted into the corresponding mounting portions, respectively, so that the supporting legs 30 are connected to the mounting portions, thereby performing fixing and supporting functions of the sofa 100.

Further, the supporting foot 30 may be a cylinder, a cube or a prism, so that the connection between the supporting foot 30 and the sofa 100 is more stable and reliable.

In some embodiments, the second magnetic element may be disposed on the outer surface of the supporting foot 30, so as to not only achieve the detachable connection of the supporting foot 30 with the seat cushion 10, the back cushion 20 or the wall surface 200, but also facilitate the timely maintenance and replacement when the magnetic force of the second magnetic element is reduced or damaged.

In other embodiments, the second magnetic elements may be disposed in the internal structure of the supporting legs 30, so as to reduce the number of the second magnetic elements, and simultaneously, the magnetic force applied to each side surface and the end surface of the supporting legs 30 is the same, which is beneficial for the magnetic connection between the supporting legs 30 and the wall surface 200 and the assembly with the seat cushion 10 and the back cushion 20.
