[0046] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Please refer to Figure 1-Figure 5 , Figure 1 It is a structural schematic diagram of a first specific embodiment of the seat turntable mechanism provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of a partially cutaway seat turntable mechanism; Figure 3 for Figure 1 A schematic diagram of the structure of the seat turntable mechanism at the second angle; Figure 4 for Figure 1 Split diagram of the seat turntable mechanism; Figure 5 for Figure 1 Schematic diagram of the structure of the fixed plate in the seat turntable mechanism.

[0048] This embodiment provides a seat turntable mechanism, comprising:

[0049] A rotating disk assembly includes a moving disk 1 and a fixed disk 2, wherein the moving disk 1 is used to connect to the seat, and the fixed disk 2 is used to connect to the vehicle floor, the moving disk 1 and the fixed disk 2 are axially limitedly connected, and can rotate relatively along the circumferential direction, a first wiring harness guide cavity is provided between the moving disk 1 and the fixed disk 2, the moving disk 1 is provided with a first wiring hole 1a connected to the first wiring harness guide cavity, and the fixed disk 2 is provided with a second wiring hole 2a connected to the first wiring harness guide cavity;

[0050] A wire harness storage box 3, the wire harness storage box 3 is connected to the side of the fixed plate 2 facing away from the movable plate 1, the wire harness storage box 3 has a second wire harness guide cavity 3a inside, the wire harness storage box 3 is provided with a first wire outlet 3b and a second wire outlet 3c, the first wire outlet 3b and the second wire outlet 3c are both connected to the second wire harness guide cavity 3a;

[0051] The wiring harness assembly 4 passes through the second wiring harness guide cavity 3a, the second wiring outlet 3c, the second wiring hole 2a and the first wiring harness guide cavity in sequence. The first end of the wiring harness assembly 4 passes through the first wiring outlet 3b, and the second end of the wiring harness assembly 4 passes through the first wiring hole 1a. The second end of the wiring harness assembly 4 is fixed to the movable disk 1, so that the wiring harness assembly 4 can slide inside the first wiring harness guide cavity and the second wiring harness guide cavity 3a under the driving action of the movable disk 1.

[0052] In the existing technical solutions for realizing seat rotation by using an electric turntable, due to the limitation of the structure of the electric turntable, the wiring harness can usually only bypass the electric turntable and extend upward from one side of the electric turntable, which causes the wiring harness to be too long, the external dimensions of the product to become larger, and the wiring harness may interfere with the external mechanism. When the electric turntable rotates, it may also cause problems such as entanglement.

[0053] In the seat turntable mechanism of this embodiment, a first wiring harness guide cavity is arranged between the moving disk 1 and the fixed disk 2, which is used for guiding and storing the wiring harness assembly 4 inside the rotating disk assembly. A wiring harness storage box 3 is arranged on the lower side of the fixed disk 2. The wiring harness storage box 3 has a second wiring harness guide cavity 3a inside, which is used for guiding and storing the wiring harness assembly 4 below the rotating disk assembly. The wiring harness assembly 4 is slidably installed inside the first wiring harness guide cavity and the second wiring harness guide cavity 3a. The first end of the wiring harness assembly 4 passes through the first wiring outlet 3b to connect the wiring harness of the vehicle floor. The second end of the wiring harness assembly 4 passes through the first wiring hole 1a to be used for the motor wiring harness and the wiring harness of the seat adjustment mechanism, which meets the requirements. The power supply requirements of the motor 5 and the seat adjustment mechanism; at the same time, the second end of the wiring harness assembly 4 is fixed to the moving disk 1. When the moving disk 1 rotates and the first wiring hole 1a gradually moves away from the second wiring hole 2a, under the driving action of the moving disk 1, part of the wiring harness assembly 4 will slide from the second wiring harness guide cavity 3a to the inside of the first wiring harness guide cavity; when the moving disk 1 rotates and the first wiring hole 1a gradually approaches the second wiring hole 2a, under the pushing action of the moving disk 1, part of the wiring harness assembly 4 will return from the first wiring harness guide cavity to the inside of the second wiring harness guide cavity 3a, ensuring that the wiring harness assembly 4 can smoothly follow and recover when the moving disk 1 rotates, preventing problems such as wiring harness pulling and winding.

[0054] In addition, in the seat turntable mechanism of this embodiment, the wiring harness assembly 4 does not need to bypass the rotating disk assembly, but can pass through the inside of the rotating disk assembly, thereby reducing the overall external dimensions of the seat turntable mechanism. The path of the wiring harness assembly 4 is shortened and does not need to occupy external space, thereby avoiding interference between the wiring harness assembly 4 and external mechanisms, thereby protecting the wiring harness assembly 4.

[0055] In summary, the seat turntable mechanism of this embodiment fully utilizes the internal space of the product, reasonably solves the wiring harness layout problem, realizes orderly wiring, has a simple structure, and has a high degree of integration of the seat turntable mechanism.

[0056] As mentioned above, there is a first wire harness guiding cavity between the moving disk 1 and the fixed disk 2. Specifically in this embodiment, the moving disk 1 is provided with a protrusion 1b, which protrudes in a direction away from the fixed disk 2. A wire harness guiding groove is formed inside the protrusion 1b. After the moving disk 1 and the fixed disk 2 are connected, the wire harness guiding groove forms the first wire harness guiding cavity.

[0057] Of course, in practice, it is also feasible to arrange the protrusion 1b on the fixed plate 2. In this case, the protrusion 1b protrudes in a direction away from the movable plate 1.

[0058] Depend on Figure 1 and Figure 2 It can be seen that in this embodiment, the first wire harness guiding cavity is an annular cavity extending along the circumference of the movable disk 1 or the fixed disk 2 , and the first wiring holes 1 a and the second wiring holes 2 a are distributed along the circumference of the movable disk 1 or the fixed disk 2 .

[0059] In this way, the wiring harness assembly 4 located inside the first wiring harness guide cavity also extends along the circumference of the movable disk 1 or the fixed disk 2, and is located between the first wiring hole 1a and the second wiring hole 2a. When the movable disk 1 rotates, the wiring harness assembly 4 can slide smoothly inside the first wiring harness guide cavity to achieve the following or recovery of the wiring harness assembly 4 and prevent problems such as wiring harness pulling and winding.

[0060] In practice, the width of the first wiring harness guide cavity can be slightly larger than the width of the wiring harness assembly 4. The first wiring harness guide cavity can guide the wiring harness assembly 4 so that the wiring harness assembly 4 only slides along the extension direction of the first wiring harness guide cavity, and will not hinder the sliding of the wiring harness assembly 4, thereby ensuring the smooth sliding of the wiring harness assembly 4 inside the first wiring harness guide cavity.

[0061] Please refer to Figure 6 , Figure 6 for Figure 1 Schematic diagram of the second structure of the fixed plate in the seat turntable mechanism.

[0062] Depend on Figure 6 It can be seen that in the second structure of the fixed disk, a first folded portion 11 is provided at one edge of the second wiring hole 2a away from the first wiring hole 1a, and the first folded portion 11 is folded toward the direction close to the movable disk 1.

[0063] In this way, when the movable disk 1 rotates and the first wiring hole 1a gradually moves away from the second wiring hole 2a, part of the wiring harness assembly 4 located inside the second wiring harness guide cavity 3a can smoothly pass through the second wiring hole 2a under the guidance of the first folding portion 11, and slide into the first wiring harness guide cavity, thereby avoiding the inner edge of the second wiring hole 2a hindering the sliding of the wiring harness assembly 4, thereby improving the smoothness of the movement of the wiring harness assembly 4.

[0064] Furthermore, a second folded portion 12 is provided at an edge of one end of the second wiring hole 2 a close to the first wiring hole 1 a , and the second folded portion 12 is folded in a direction away from the movable disk 1 .

[0065] In this way, when the movable disk 1 rotates and the first wiring hole 1a gradually approaches the second wiring hole 2a, part of the wiring harness assembly 4 located inside the first wiring harness guide cavity can smoothly pass through the second wiring hole 2a under the guidance of the second folding portion 12, and slide to the second wiring harness guide cavity 3a, thereby avoiding the inner edge of the second wiring hole 2a hindering the sliding of the wiring harness assembly 4 and improving the smoothness of the movement of the wiring harness assembly 4.

[0066] Please continue to refer to Figure 4 , Figure 7-Figure 11 , Figure 7 for Figure 1 Schematic diagram of the structure of the drag chain in the seat turntable mechanism; Figure 8 for Figure 7 A schematic diagram of the structure of the first drag chain unit in the drag chain; Fig. 9 for Figure 7 A schematic diagram of the structure of the second drag chain unit in the drag chain; Fig.10 for Figure 7 A schematic diagram of the structure of the second drag chain unit in the drag chain; Fig.11 for Fig.10 Schematic diagram of the structure of the second drag chain unit at a second angle.

[0067] In this embodiment, the wiring harness assembly 4 includes a wiring harness body 41 and a wiring harness protector. The wiring harness body 41 is partially fixed inside the wiring harness protector, and both ends of the wiring harness body 41 pass through the inside of the wiring harness protector. The wiring harness protector can at least swing around a first axis and a second axis. The first axis extends along a first direction, and the second axis extends along a second direction. The length direction of the wiring harness protector is a third direction, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0068] As configured above, the harness protector can protect the harness body 41 and prevent the harness body 41 from being worn during the sliding process; at the same time, the harness protector is fixed on the outer periphery of the harness body 41 and can also support the harness body 41 to ensure that the harness assembly 4 can smoothly follow and recover when the moving disk 1 rotates. In addition, the structure of the harness protector can adapt to the three-dimensional path, so that the harness assembly 4 can be deformed into the desired shape with the structure of the first harness guide cavity and the second harness guide cavity 3a, and then the harness assembly 4 can smoothly slide inside the first harness guide cavity and the second harness guide cavity 3a.

[0069] The harness protection member may be a corrugated tube, so that the harness protection member can swing in any direction.

[0070] Or, if Figure 7-Figure 11 As shown, the harness protection member is a drag chain 42, which includes a plurality of first drag chain units 421 and a plurality of second drag chain units 422, the first drag chain units 421 and the second drag chain units 422 are spaced apart, the first drag chain unit 421 and the second drag chain unit 422 adjacent to the first end are hinged and can swing around a first axis 423, and the first drag chain unit 421 and the second drag chain unit 422 adjacent to the second end are hinged and can swing around a second axis 424. In this way, the drag chain 42 can swing around the first direction and the second direction.

[0071] The first drag chain unit 421 and the second drag chain unit 422 each include a main body 42A and two connecting plates 42B. The main body 42A is a tubular structure. The two connecting plates 42B are connected to a first end of the main body 42A. The two connecting plates 42B in the first drag chain unit 421 are arranged opposite to each other along a first direction. The opposite side walls of the two connecting plates 42B are correspondingly provided with a first protrusion A1. The opposite side walls of the main body 42A in a second direction are correspondingly provided with a first hinge hole A2.

[0072] The two connecting plates 42B in the second drag chain unit 421 are arranged opposite to each other along the second direction, the opposite side walls of the two connecting plates 42B are correspondingly provided with second protrusions B1, and the two side walls of the main body 42A opposite to each other in the first direction are correspondingly provided with second hinge holes B2;

[0073] In the connected state, the connecting plate 42B in the first drag chain unit 421 is located inside the main body 42A in the second drag chain unit 422 at the adjacent first end, and the first protrusion A1 and the second hinge hole B2 are correspondingly plug-fitted to realize the hinge of the first drag chain unit 421 and the second drag chain unit 422 at the adjacent first end. The extension direction of the first protrusion A1 is the first direction, and the axis of the first protrusion A1 is the first axis 423; the connecting plate 42B in the second drag chain unit 422 at the adjacent second end is located inside the main body 42A in the first drag chain unit 421, and the second protrusion B1 and the first hinge hole A2 are correspondingly plug-fitted to realize the hinge of the first drag chain unit 421 and the second drag chain unit 422 at the adjacent second end. The extension direction of the second protrusion B1 is the second direction, and the axis of the second protrusion B1 is the second axis 424.

[0074] Thus, the first drag chain units 421 and the second drag chain units 422 are alternately distributed and connected to form a long drag chain 42 .

[0075] Of course, in practice, the first drag chain unit 421 and the second drag chain unit 422 are not limited to the above-mentioned structural forms. For example, the two connecting plates 42B in the first drag chain unit 421 are correspondingly provided with the second hinge holes B2, and the two side walls in the first direction opposite to each other in the body 42A of the second drag chain unit 422 are correspondingly provided with the first protrusions A1; or, the two side walls in the second direction opposite to each other in the body 42A of the first drag chain unit 421 are correspondingly provided with the second protrusions B1, and the two connecting plates 42B in the second drag chain unit 422 are correspondingly provided with the first hinge holes A2.

[0076] In this embodiment, in the connected state, the connecting plate 42B in the first drag chain unit 421 is located inside the main body 42A in the adjacent first end second drag chain unit 422. In practice, it is also feasible that the connecting plate 42B in the first drag chain unit 421 is located outside the main body 42A in the adjacent first end second drag chain unit 422. In this case, the first protrusion A1 is provided on the side walls of the two connecting plates 42B facing each other.

[0077] In this embodiment, in the connected state, the connecting plate 42B in the adjacent second end second drag chain unit 422 is located inside the main body 42A in the first drag chain unit 421. In practice, it is also feasible that the connecting plate 42B in the adjacent second end second drag chain unit 422 is located outside the main body 42A in the first drag chain unit 421. In this case, the second protrusion B1 is provided on the side walls of the two connecting plates 42B facing each other.

[0078] Please continue to refer to Figure 3 , Figure 4 and Fig.12 , Fig.12 for Figure 1 Schematic diagram of the structure of the wire harness storage box in the seat turntable mechanism.

[0079] In this embodiment, the wire harness storage box 3 is an arc-shaped tubular structure, and an arc-shaped second wire harness guide cavity 3a is formed inside the wire harness storage box 3. A notch portion A is provided on the side wall of the wire harness storage box 3 facing away from the fixed disk 2. The notch portion A extends along the extension direction of the wire harness storage box 3. The first end of the wire harness assembly 4 passes through the notch portion A. The first end of the wire harness assembly 4 can slide along the extension direction of the notch portion A under the driving action of the moving disk 1. The notch portion A forms a first wire outlet 3b, and one of the ports of the wire harness storage box 3 forms a second wire outlet 3c.

[0080] In this embodiment, the wire harness storage box 3 is configured as an arc-shaped tubular structure, which can extend the path of the second wire harness guide cavity 3a, ensuring that there is sufficient storage space inside the wire harness storage box 3 for storing the wire harness assembly 4; at the same time, the second wire harness guide cavity 3a is configured as an arc-shaped structure, so that the wire harness assembly 4 can slide smoothly inside the second wire harness guide cavity 3a.

[0081] Depend on Fig.12 It can be seen that in this embodiment, the inner wall of the second wire outlet 3c is connected to the outer wall of another port of the wire harness storage box 3. In this way, the wire harness storage box 3 is surrounded by a ring structure, which improves the structural strength of the wire harness storage box 3 and ensures the structural stability of the wire harness storage box 3.

[0082] Please refer to Figure 13-14 , Fig.13 It is a structural schematic diagram of a second specific embodiment of the seat turntable mechanism provided by the utility model; Fig.14 for Fig.13 Schematic diagram of the structure of the wire harness storage box in the seat turntable mechanism.

[0083] In this embodiment, the wire harness storage box 3 is an arc-shaped tubular structure, and an arc-shaped second wire harness guide cavity 3a is formed inside the wire harness storage box 3. The inner wall of the wire harness storage box 3 is provided with a notch portion A, and the notch portion A extends along the extension direction of the wire harness storage box 3. The first end of the wire harness assembly 4 passes through the notch portion A. The first end of the wire harness assembly 4 can slide along the extension direction of the notch portion A under the driving action of the moving disk 1. The notch portion A forms a first wire outlet 3b, and one of the ports of the wire harness storage box 3 forms a second wire outlet 3c.

[0084] It can be seen that in this embodiment, the notch portion A is arranged on the inner wall of the wire harness storage box 3 or the side wall of the wire harness storage box 3 facing away from the fixed plate 2, and the first end of the wire harness assembly 4 passes through the notch portion A. The wire harness assembly 4 does not exceed the outer edge of the wire harness storage box 3. The wire harness assembly 4 does not affect the overall external dimensions of the seat turntable mechanism, does not need to occupy external space, and avoids interference between the wire harness assembly 4 and external mechanisms.

[0085] In this embodiment, the width of the second wiring harness guide cavity 3a is slightly larger than the width of the wiring harness assembly 4. The width of the wiring harness assembly 4 is also the width of the drag chain 42. The second wiring harness guide cavity 3a can guide the wiring harness assembly 4 so that the wiring harness assembly 4 only slides along the extension direction of the second wiring harness guide cavity 3a, and will not hinder the sliding of the wiring harness assembly 4, thereby ensuring the smooth sliding of the wiring harness assembly 4 inside the second wiring harness guide cavity 3a.

[0086] Among them, the first end of the wiring harness assembly 4 passes through the inside of the notch portion A, specifically, the first end of the wiring harness body 41 passes through the inside of the notch portion A. Therefore, the width of the notch portion A should be larger than the width of the wiring harness body 41 and smaller than the width of the drag chain 42, to ensure that the wiring harness assembly 4 can be stably mounted inside the second wiring harness guide cavity 3a, and the wiring harness body 41 can slide smoothly inside the notch portion A.
