[0031] In one embodiment, referring to FIGS. 7a-7d, FIGS. 7a-7d are schematic diagrams of sliding rails of the modular sofa bed according to the present disclosure. As shown in FIG. 7a, front ends and rear ends of the sliding rails 8 are inclined to form suspended ends; the suspended ends are used to secure the seat board modules 5, and the middle sections of the sliding rails 8 are horizontally arranged to enable sliding of the seat board modules 5.

[0032] As shown in FIGS. 7b-7d, specifically, the sliding rails 8 are pre-installed in the hollow base frames 4 using screws. When wheels of a certain seat board module 5 are at the front ends 81 of corresponding sliding rails 8, the wheels at the bottom of this seat board module 5 are in a suspended state, resulting in the seat board module 5 being fixed within the corresponding hollow base frame 4; when this seat board module 5 is being pulled from the front ends 81 of the sliding rails 8 to the middle sections 82 of the sliding rails 8, the wheels at the bottom of the seat board module 5 lift the module, resulting in the seat board module 5 separating from the hollow base frame 4 and sliding relative to the hollow base frame 4; when the seat board module 5 is further pulled from the middle sections 82 of the sliding rails 8 to the rear ends 83 of the sliding rails 8, the wheels at the bottom of the seat board module 5 will again reach a suspended state, resulting in the seat board module 5 being again fixed within the hollow base frame 4 and realizing extension of the modular sofa bed. This process can apply to one or more of the seat board modules.

[0033] When the wheels of a certain seat board module 5 are at the rear ends 83 of corresponding sliding rails 8, the wheels at the bottom of the seat board module 5 are in a suspended state, resulting in the seat board module 5 being fixed within the corresponding hollow base frame 4; when this seat board module 5 is being pushed from the rear ends 83 of the sliding rails 8 to the middle sections 82 of the sliding rails 8, the wheels at the bottom of the seat board module 5 lift the module, resulting in the seat board module 5 separating from the hollow base frame 4 and sliding relative to the hollow base frame 4; when the seat board module 5 is further pushed from the middle sections 82 of the sliding rails 8 to the front ends 81 of the sliding rails 8, the wheels at the bottom of the seat board modules 5 will again reach a suspended state, resulting in the seat board module 5 being again fixed within the hollow base frame 4 and realizing retraction of the modular sofa bed. This process can apply to one or more of the seat board modules.

[0034] The modular sofa bed according to the present disclosure, connection components such as the K/D detachable hinges 6, the K/D connecting plates 7, the connecting footboards 9, and corresponding metal brackets can be assembled and disassembled simply by hooking them together, without tools. This method ensures that the assembly and disassembly are convenient and quick, while ensuring a solid structure of the assembled sofa bed.

[0035] The design of extension and retraction of the modular sofa bed according to the present disclosure, not only facilitates an easier conversion between sofa and bed, enhancing the convenience of using the sofa bed, but also incorporates a storage function. Additionally, the wheels on the seat board modules allow it to slide relative to the hollow base frames and the floor, reducing damage to the sofa bed.

[0036] The modular sofa bed according to the present disclosure utilizes modular components such as armrests, backs, and bases, enabling industrial production on assembly lines. This approach effectively improves production efficiency, reduces labor costs, and facilitates transportation and movement. The assembly is completed by connecting the modules with tool-free connectors, significantly enhancing the convenience of assembly and disassembly. This not only improves the efficiency for users but also ensures high stability. Since the connectors can be pre-installed at the factory or attached by users themselves without tools, the assembly process is quick and highly convenient. The application features a variety of cleverly designed connectors that allow for flexible combinations and diverse arrangements, enabling the creation of multiple sofa specifications. The design is both reasonable and ingenious, with secure connections and reliable safety, making it highly promotable and valuable.
