Description
Technical Field
[0001] This utility model relates to the field of smart home technology, and in particular to a hidden movable base for a smart home sofa. Background Technology
[0002] With the rapid development of the smart home industry, user demand for home products has shifted from single-function to "aesthetic adaptation, functional integration, and spatial flexibility." Modern home space design increasingly emphasizes a simple and unified visual effect. The exposed casters on traditional sofa bases not only detract from the aesthetics of the space but also easily accumulate dust, snag carpets, and are not stable enough when stationary. Meanwhile, as urbanization progresses and living spaces become more compact, users need sofas with flexible movement capabilities to adapt to different scenarios (such as adjusting living room layout, cleaning the space under the sofa, and temporarily expanding activity areas). Furthermore, the modularity and adaptability of smart home products are becoming increasingly prominent. Users expect bases to be compatible with different sofa styles and easy to operate, switching modes without the need for special tools. Against this backdrop, concealed movable bases have emerged, solving the pain points of traditional sofas while aligning with the "human-centered" design philosophy of smart homes.
[0003] To address this, we propose a hidden movable base for smart home sofas. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hidden movable base for smart home sofas.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A smart home sofa with a hidden movable base includes a sofa body, two armrests are fixedly installed on the upper surface of the sofa body, and four fixing plates are fixedly installed on the lower surface of the sofa body by bolts. A hidden movable component is installed on the lower surface of the fixing plates.
[0006] As a further embodiment of this utility model: the concealed moving component includes a sleeve, the sleeve is fixedly installed on the lower surface of the fixed plate, a rotating shaft is rotatably connected inside the sleeve, and a fixed cylinder is fixedly installed at the bottom end of the rotating shaft, the fixed cylinder being hollow.
[0007] As a further improvement of this utility model: an arc-shaped notch is provided on one side of the fixed cylinder, an adjusting wheel is rotatably connected inside the arc-shaped notch, a threaded rod is fixedly installed inside the adjusting wheel, and the top end of the threaded rod is rotatably connected to the fixed cylinder.
[0008] As a further embodiment of this utility model: a support block is slidably connected inside the fixed cylinder, the support block is circular, and the bottom end of the threaded rod is threadedly connected to the upper surface of the support block.
[0009] As a further improvement of this utility model: guide grooves are provided on both sides of the fixed cylinder, and guide blocks are slidably connected inside the guide grooves, and the guide blocks are fixedly connected to the support blocks.
[0010] As a further embodiment of this utility model: a connecting block is fixedly installed on one side of the fixed cylinder. The connecting block is U-shaped, and a wheel is rotatably connected inside the connecting block via a rotating shaft.
[0011] Compared with the prior art, this utility model provides a hidden movable base for smart home sofas, which has the following advantages: The core highlight of this invention, a hidden movable base for smart home sofas, lies in its deep integration of movable functionality with a concealed structure, overcoming the traditional sofa base's limitation of "mutability and stability being mutually exclusive." Through a transmission structure comprised of a sleeve, a rotating shaft, and a fixed cylinder, the wheels are mounted to one side of the fixed cylinder via a U-shaped connecting block. Under normal conditions, the sofa can be stably parked by the support block's contact with the ground, completely concealing the movable components and avoiding the unsightly appearance of traditional exposed roller bases. Simultaneously, guide grooves on both sides of the fixed cylinder and guide blocks on the support block form a sliding limit structure. Combined with the threaded transmission design of the threaded rod and adjusting wheel, rotating the adjusting wheel drives the support block to slide up and down along the fixed cylinder, achieving rapid switching between "supported and fixed" and "unlocked and movable." This ensures the sofa's stability when stationary while also providing flexible mobility, perfectly meeting the core demands of modern smart homes for space utilization, visual unity, and functional diversity.
[0012] Another major highlight of this invention is the high adaptability and reliability brought by its modular design. The concealed moving component is fixed to the sofa body with bolts via four fixing plates, making assembly and disassembly convenient and adaptable to smart home sofas of different sizes. The rotating connection structure between the rotating shaft and the sleeve allows the sofa to flexibly adjust its direction during movement. Combined with the rolling characteristics of the wheels, it can easily turn and move even in narrow home spaces. The arc-shaped notch provides reasonable installation space for the adjusting wheels without affecting the structural strength of the fixing cylinder; the threaded connection between the threaded rod and the support block has high precision, making the rotation of the adjusting wheels effortless, and the cooperation between the guide block and the guide groove effectively prevents the support block from shifting, ensuring a stable and smooth transmission process. The overall structure is made of rigid materials, with tight connections between all components, low wear, long service life, and no need for complicated maintenance, fully meeting the expectations of smart home users for "convenient operation and long-term durability".
[0013] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0018] Example: A hidden movable base for a smart home sofa, such as Figures 1-4 As shown, the sofa includes a sofa body 1, with two armrests 2 fixedly installed on the upper surface of the sofa body 1, and four fixing plates 3 fixedly installed on the lower surface of the sofa body 1 by bolts. A hidden moving component 4 is installed on the lower surface of the fixing plate 3.
[0019] like Figures 1-4As shown, the concealed moving component 4 includes a sleeve 5. The sleeve 5 is fixedly installed on the lower surface of the fixing plate 3. A rotating shaft 6 is rotatably connected inside the sleeve 5. A fixing cylinder 7 is fixedly installed at the bottom end of the rotating shaft 6. The fixing cylinder 7 is hollow. An arc-shaped notch 8 is opened on one side of the fixing cylinder 7. An adjusting wheel 9 is rotatably connected inside the arc-shaped notch 8. A threaded rod 10 is fixedly installed inside the adjusting wheel 9. The top end of the threaded rod 10 is rotatably connected to the fixing cylinder 7. A support block 11 is slidably connected inside the fixing cylinder 7. The support block 11 is circular. The bottom end of the threaded rod 10 is threadedly connected to the upper surface of the support block 11. Guide grooves 12 are provided on both sides of the fixed cylinder 7. Guide blocks 13 are slidably connected inside the guide grooves 12. The guide blocks 13 are fixedly connected to the support blocks 11. A connecting block 14 is fixedly installed on one side of the fixed cylinder 7. The connecting block 14 is U-shaped. A wheel 15 is rotatably connected inside the connecting block 14 through a rotating shaft. Under normal conditions, the support block 11 is in the extended state by the threaded locking of the threaded rod 10. The lower surface of the support block 11 is in close contact with the ground. The support force of the support block 11 is used to firmly fix the sofa body 1. At this time, the wheel 15 is in a suspended and hidden state to prevent the sofa from sliding at will. When the sofa needs to be moved, the adjusting wheel 9 inside the arc-shaped notch 8 on one side of the fixed cylinder 7 is rotated. The adjusting wheel 9 drives the internally fixed threaded rod 10 to rotate synchronously. Since the top end of the threaded rod 10 is rotatably connected to the fixed cylinder 7 and the bottom end is threadedly engaged with the support block 11, and the support block 11 forms a sliding limit with the guide groove 12 of the fixed cylinder 7 through the guide block 13, the rotation of the threaded rod 10 is converted into the upward sliding of the support block 11 along the axial direction of the fixed cylinder 7 until the support block 11 leaves the ground, and the wheel 15 contacts the ground and bears the overall weight of the sofa. At this time, through the rotational cooperation between the rotating shaft 6 and the sleeve 5, the sofa can be moved in any direction by the rolling of the wheel 15.
[0020] Working Principle: The working principle of this concealed mobile base is based on a composite transmission logic of "threaded drive + sliding limit + rotational connection" to achieve stable parking and flexible movement of the sofa. Under normal conditions, the support block 11 is extended through the threaded locking of the threaded rod 10, with its lower surface tightly against the ground. The support block 11 provides stable support for the sofa body 1, and the wheels 15 are suspended and concealed, preventing the sofa from sliding freely. When the sofa needs to be moved, the adjusting wheel 9 inside the arc-shaped notch 8 on one side of the fixed cylinder 7 is rotated. The adjusting wheel 9 drives the internally fixed threaded rod 10 to rotate synchronously. Since the top of the threaded rod 10 is rotatably connected to the fixed cylinder 7 and the bottom is threadedly engaged with the support block 11, and the support block 11 forms a sliding limit with the guide groove 12 of the fixed cylinder 7 through the guide block 13, the rotation of the threaded rod 10 is converted into the upward sliding of the support block 11 along the axial direction of the fixed cylinder 7 until the support block 11 lifts off the ground, and the wheels 15 contact the ground and bear the overall weight of the sofa. At this time, through the rotational cooperation of the rotating shaft 6 and the sleeve 5, the sofa can move in any direction by the rolling of the wheel 15. After moving to the target position, the adjusting wheel 9 is rotated in the opposite direction, the support block 11 slides down to reset and supports the ground again, and the wheel 15 is suspended and hidden again, completing the complete operation cycle of "movement-fixation".
[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
