Description

Technical Field

[0001] This utility model relates to the field of smart home technology, and in particular to a sofa rotating base. Background Technology

[0002] The base of an electric swivel sofa can rotate 360°. However, because the sofa is connected to a power cord, the cord can easily become tangled during the rotation process, causing inconvenience to the use of the sofa.

[0003] Chinese patent CN213344962U discloses a rotating base assembly for an electric chair. The rotating base assembly includes a circular structure, which essentially comprises a planar or slightly spherical circular plate or platform. An upright support column extends vertically upward from the axial central portion of the rotating base assembly to mount the electric chair. Incoming power lines are routed below the platform of the rotating base assembly and upward through the upright support column, thereby electrically connecting to the lower part of a slip ring assembly mounted on the upper end of the upright support column. Outgoing power lines are electrically connected at their lower ends to the upper part of the slip ring assembly. Regardless of how many times the electric recliner rotates relative to the rotating base, the power lines do not coil, twist, or become tangled. However, this design still has the following technical drawbacks:

[0004] 1) The rotating base assembly includes a base, which includes a plurality of radially extending spokes, a boss is provided in the central part of the base, the plurality of radially extending spokes interconnect the base to the flat boss, and a slip ring assembly is provided on the boss. The structure is complex and the slip ring assembly is difficult to assemble.

[0005] 2) Once a malfunction occurs, replacing the slip ring assembly requires disassembling multiple parts for inspection, resulting in high maintenance costs and time consumption;

[0006] 3) Low space utilization: The internal space of the upright column or platform is limited, making it difficult to accommodate multiple sets of wiring harnesses or additional wiring required for future functional expansion. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a sofa rotating base in order to solve the problems existing in the prior art in the background art.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a sofa rotating base, including a base and a slip ring assembly. The inner wall of the base is provided with intersecting spokes. A fixed plate is installed at the center above the spokes. A rotating plate is provided above the fixed plate. The fixed plate and the rotating plate are assembled by an installation assembly. The fixed plate and the rotating plate are axially fixed, and the rotating plate can rotate circumferentially relative to the fixed plate. The slip ring assembly is disposed on the spokes. The slip ring assembly includes a fixed wire harness, a rotating wire harness and a slip ring. The rotating wire harness can rotate synchronously with the rotating plate.

[0009] Furthermore, the slip ring is fitted with a mounting sleeve, and one side of the mounting sleeve is provided with a first lug and a second lug that are arranged opposite to each other. A groove is formed between the first lug and the second lug, and the mounting sleeve is secured to the spoke through the groove.

[0010] Furthermore, the spokes are hollow structures, and the spokes are provided with second mounting holes that are opposite each other. The slip ring is fitted with a mounting sleeve, and one side of the mounting sleeve is provided with a first lug and a second lug that are opposite each other. The spokes are located between the first lug and the second lug. The first lug is provided with a third mounting hole, and the second lug is provided with a fourth mounting hole. The second fastener passes through the third mounting hole, the second mounting hole and the fourth mounting hole in sequence to fix the mounting sleeve on the spokes.

[0011] Furthermore, the spokes are provided with a first mounting hole, the fixed plate is provided with a first assembly hole, and the first fastener fixes the fixed plate to the spokes through the first assembly hole and the first mounting hole.

[0012] Furthermore, the rotating disk is provided with a second mounting hole, through which the rotating disk is fixedly connected to the main body of the sofa.

[0013] Furthermore, both the fixed disk and the rotating disk are fitted onto the mounting assembly. The fixed disk is fixedly connected to the mounting assembly, and the rotating disk can rotate circumferentially relative to the mounting assembly. The fixed disk and the rotating disk are axially fixed by gaskets and pressure rings.

[0014] Furthermore, the fixed disk has a first slide rail on the surface facing the rotating disk, and the rotating disk has a second slide rail on the surface opposite to the fixed disk. The first slide rail and the second slide rail cooperate to form a groove, and the groove contains ball bearings.

[0015] Furthermore, the spokes are provided with threading holes, a central hole is provided at the intersection of the spokes, and a through hole is provided in the middle of the mounting assembly. The rotating wire harness passes through the threading holes into the interior of the spokes and exits through the through hole of the mounting assembly.

[0016] Furthermore, multiple support feet are provided on the bottom surface of the base.

[0017] The beneficial effects of this utility model are:

[0018] 1) By using spokes as the carrier of slip ring assembly, 360-degree winding-free rotation is achieved, reducing the assembly difficulty of slip ring assembly, making full use of the spatial openness and air circulation of spokes, significantly improving heat dissipation efficiency, reducing cable temperature rise, and extending service life.

[0019] 2) The slip ring assembly is mounted on the spokes, making it easy to disassemble and eliminating the need for complex disassembly during maintenance, thus greatly reducing maintenance difficulty;

[0020] 3) Make full use of the spokes to reserve wiring space for future functional upgrades and improve the product's scalability. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] like Figures 1-3 The illustration shows a sofa swivel base for use with a sofa. It includes a base 1 with intersecting spokes 2 inside. The base 1 and spokes 2 together form a support base, which serves as the main support structure for the sofa swivel base, providing support and stability for the sofa. The spokes 2 have a square cross-section with a central cavity to provide a channel for threading wires. Multiple support legs 11 are provided on the bottom surface of the base 1.

[0031] A central hole 21 is provided at the intersection of the two spokes 2. The spokes 2 are provided with a first mounting hole 22, a second mounting hole 23, and a threading hole 24. A fixed plate 3 is fixedly disposed above the center of the spokes 2. Specifically, the fixed plate 3 is provided with a first assembly hole 31. A first fastener is used to fix the fixed plate 3 to the spokes 2 through the first assembly hole 31 and the first mounting hole 22. A rotating plate 4 is provided above the fixed plate 3. The fixed plate 3 and the rotating plate 4 are assembled by a mounting assembly 6. Specifically, both the fixed plate 3 and the rotating plate 4 are fitted onto the mounting assembly 6. The fixed plate 3 is fixedly connected to the mounting assembly 6. The rotating plate 4 can rotate circumferentially relative to the mounting assembly 6, thereby allowing the rotating plate 4 to rotate circumferentially relative to the fixed plate 3. The rotating plate 4 is axially pressed by a gasket 62 and a pressure ring 63 to prevent axial movement of the rotating plate 4 during rotation. The rotating disk 4 is also provided with a second mounting hole 41. The rotating disk 4 is connected to the main body of the sofa (not shown in the figure) through the second mounting hole 41, so that the main body of the sofa can rotate relative to the support base and the fixed disk 3.

[0032] The slip ring assembly 5 is mounted on the spokes 2. The slip ring assembly 5 includes a fixed wire harness 51, a rotating wire harness 52, and a slip ring 53. The fixed wire harness 51 and the rotating wire harness 52 are located on opposite sides of the slip ring 53. The slip ring 53 is existing technology. The slip ring 53 allows the rotating wire harness 52 to rotate relative to the fixed wire harness 51, and when the rotating wire harness 52 rotates, the fixed wire harness 51 and the rotating wire harness 52 form a conductive contact. The fixed wire harness 51 is connected to an external power supply or control module. The rotating wire harness 52 passes through the wire hole 24 of the spoke 2 into the spoke 2, enters the center hole 21, and exits through the through hole 61 of the mounting assembly 6. The rotating wire harness 52 is connected to electrical equipment in the main body of the sofa. When the main body of the sofa rotates relative to the support base, the rotating wire harness 52 rotates synchronously with the rotating disc 4.

[0033] like Figures 4-5 As shown, the fixed disk 3 has a first slide rail 32 on its surface facing the rotating disk 4, and the rotating disk 4 has a second slide rail 42 on its surface opposite to the fixed disk 3, which cooperates with the first slide rail 32. The first slide rail 32 and the second slide rail 42 cooperate to form a groove, and a ball bearing 7 is provided in the groove. When the rotating disk 4 rotates relative to the fixed disk 3, the ball bearing 7 can reduce the friction between the two and make the rotation smoother.

[0034] like Figure 6As shown, a mounting sleeve 8 is fitted onto the slip ring assembly 5. One side of the mounting sleeve 8 has a first lug 81 and a second lug 82 arranged opposite to each other. A groove 83 is formed between the first lug 81 and the second lug 82. The first lug 81 has a third mounting hole 84, and the second lug 82 has a fourth mounting hole 85. The mounting sleeve 8 is secured to the spoke 2 through the groove 83 and fixed to the spoke 2 by the second fastener 9. With this configuration, the slip ring assembly 5 can be easily installed on the spoke 2. The slip ring assembly 5 is easy to install and remove, improving the assembly efficiency of the slip ring assembly 5 and making the replacement and maintenance of the slip ring assembly 5 more convenient.

[0035] More specifically, the mounting sleeve 8 is fitted onto the slip ring 53 of the slip ring assembly 5, the spoke 2 is inserted into the groove 83 between the first lug 81 and the second lug 82, and the second fastener 9 passes through the third mounting hole 84, the second mounting hole 23 on the spoke 2 and the fourth mounting hole 85 in sequence to assemble the mounting sleeve 8 onto the spoke 2.

[0036] Connect the fixed wiring harness 51 of the slip ring assembly 5 to an external power source. The rotating wiring harness 52 of the slip ring assembly 5 is inserted into the wire hole 24, then into the through hole 61 of the mounting assembly 6, and finally out of the through hole 61 to connect with the electrical equipment of the main body of the sofa. When the user rotates the main body of the sofa, the rotating disk 4 rotates relative to the fixed disk 3, and the rotating wiring harness 52 located on one side of the slip ring 53 also rotates accordingly, thereby preventing the rotating wiring harness 52 from being tangled and pulled when the main body of the sofa rotates, achieving the effect of normal and safe use.

[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
