Its foldable or unfoldable design allows for flexible switching between the two modes. This device is typically used in space-saving small apartments, rental properties, or situations requiring temporary accommodation, satisfying daily sitting needs while quickly transforming into a bed.

[0003] Existing sofa beds have a relatively complex structure and an unreasonable design. In actual use, the sofa bed can be adjusted into three modes: recliner, sofa, and bed. However, if the foam pad is directly laid on the sofa bed, the foam pad is prone to displacement, which affects the actual user experience. To address this problem, the inventor designed a modular sofa bed. Utility Model Content

[0026] The reinforcement component 3 includes a fixing post 31, a connecting groove 36, a hemispherical post 34, and a connecting rope 35. The fixing posts 31 are distributed on both sides of the sofa bed frame 1, with four sets of fixing posts 31 on one side, and every two sets of fixing posts 31 are on the same vertical horizontal line. The connecting groove 36 is opened inside any set of fixing posts 31, and the connecting groove 36 is symmetrically distributed inside the fixing posts 31. The hemispherical post 34 is inserted into the connecting groove 36, and the connecting rope 35 is fixed to the surface of the hemispherical post 34.

[0027] The fixed column 31 provides structural support and a magnet mounting position. The connecting groove 36 is used to accommodate the hemispherical column 34, which is inserted into the fixed column 31. Then, the first sponge pad 22 or the second sponge pad 23 is fixed together with the movable frame 13 by the connecting rope 35.

[0028] A first magnet block 32 is fixed inside the fixed column 31, and a second magnet block 33 is magnetically connected to the surface of the first magnet block 32. The surface of the second magnet block 33 is fixed to the surface of the hemispherical column 34.

[0029] By connecting the first magnet block 32 and the second magnet block 33, the hemispherical column 34 can be fixed inside the fixed column 31;

[0030] The sofa bed frame 1 includes a main frame 11, a support frame 12, and a movable frame 13; the support frame 12 is fixed to the outer surface of one end of the main frame 11, and the movable frame 13 is arranged on both sides of the main frame 11, with the surface of the movable frame 13 fixed to the surface of the fixed column 31.

[0031] The main frame 11 is the basic support structure that bears the main weight of the sofa bed. The support frame 12 is used for the user to lean against the sofa bed. The movable frame 13 is a key movable component that can switch between sofa, recliner and bed modes by rotating and fixing.

[0032] The bottom of the movable frame 13 has straight slots 14 at both ends, and the main frame 11 and the movable frame 13 are connected by screws 15, with the screws 15 located inside the straight slots 14.

[0033] The straight slot 14 is used to engage with the screw 15 to lock the movable frame 13 at the desired angle position;

[0034] The movable frame 13 has internally fixed support shafts 16 at both ends, and the outer surface of the support shafts 16 is rotatably connected to rotating columns 17.

[0035] The support shaft 16 is used to rotate the rotating column 17 on its surface, and the rotating column 17 is used to stably fix the movable frame 13 in the desired horizontal state.

[0036] The rotating column 17 includes a rotating part 171, a supporting part 172, and a chamfered surface 173. The rotating part 171 and the supporting part 172 are designed as a single unit. The rotating part 171 is located outside the supporting shaft 16, and the chamfered surface 173 is located at the bottom of the rotating part 171. The angle between the chamfered surface 173 and the supporting part 172 is 120 degrees to 150 degrees.

[0037] The rotating part 171 is used to change the angle of the rotating column 17, the supporting part 172 is used to contact the ground, thereby fixing the movable frame 13 in the required position, and the oblique surface 173 allows the rotating column 17 to be properly stored when it retracts into the movable frame 13.

[0038] The support component 2 includes a main sponge pad 21, a first sponge pad 22, and a second sponge pad 23. The main sponge pad 21 is laid on the top of the main frame 11, the first sponge pad 22 is laid on the surface of one side of the movable frame 13, and the second sponge pad 23 is laid on the surface of the other side of the movable frame 13. The thickness of the first sponge pad 22 and the second sponge pad 23 is less than the thickness of the main sponge pad 21. The surfaces of the first sponge pad 22 and the second sponge pad 23 are fixed to the connecting rope 35.

[0039] Working principle: When the sofa bed needs to be adjusted to sofa mode, a rotational force is applied to the movable frames 13 on both sides, causing the movable frames 13 to tilt. Then, screws 15 are passed through the main frame 11 and the straight groove 14 and fixed to the inside of the movable frame 13. Then, the main sponge pad 21 is laid on the top of the main frame 11, and the first sponge pad 22 and the second sponge pad 23 are laid on the surface of the movable frame 13. The hemispherical column 34 is aligned with the connecting groove 36 and inserted into the inside of the fixing column 31, so that the first magnet 32 ​​and the second magnet 33 are connected together.

[0040] When the sofa bed needs to be adjusted to a recliner position, first remove the hemispherical column 34 on one side from the inside of the fixed column 31, remove the second sponge pad 23 from the surface of the movable frame 13, remove the screw 15 inside the movable frame 13 on one side, then align the movable frame 13 with the main frame 11 on the same horizontal line, apply a flipping force to the support part 172 under the action of the support shaft 16, so that the rotating part 171 is in a vertical state, and then fix the screw 15 in the required position in the above manner, and fix the second sponge pad 23 to the top of the movable frame 13.

[0041] When the sofa bed needs to be adjusted to a lying position, the above method is used to adjust the movable frame 13 on the other side to the same horizontal line as the main frame 11, and adjust the position of the first sponge pad 22 so that the first sponge pad 22, the second sponge pad 23 and the main sponge pad 21 are on the same horizontal line.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
