Description

Technical Field

[0001] This application relates to the field of vehicle seat technology, and in particular to a seat rotation assembly and a vehicle. Background Technology

[0002] To enrich the seating options in car cabins, many models are equipped with rotatable seats, allowing for applications such as rotating the seats 90° to welcome guests, enjoy the view, or rotating them 180° to allow for face-to-face communication with rear passengers.

[0003] In related technologies, electric rotating discs are often used to install seats. The electric rotating disc is installed on the vehicle body or on the slide rails for the seat to move back and forth. The seat is then fixed to the electric rotating disc, which drives the seat to complete the rotation movement at a set angle.

[0004] However, the aforementioned electric rotating discs have complex structures, are heavy, and costly. The drive structure often uses a motor to drive a gear plate or rack. However, this structure has a certain tooth meshing clearance, resulting in a large clearance in the rotational transmission. This causes issues such as jamming and play during seat rotation and steering, requiring an additional mechanism to eliminate the clearance. This leads to higher manufacturing costs and increased weight for the electric rotating disc, and the assembly of the entire mechanism is also more complex. Utility Model Content

[0005] In view of this, this application aims to provide a seat rotation assembly to offer a seat rotation drive solution that helps to improve transmission fit clearance issues.

[0006] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0007] A seat rotation assembly,

[0008] It includes a fixed disk, a rotating disk rotatably disposed on the fixed disk, a drive device disposed on the fixed disk, and a drive disk and a floating disk that are drively connected between the drive device and the rotating disk;

[0009] The drive disk is located in the middle of the fixed disk and can rotate under the drive of the drive device; the floating disk is slidably disposed on the drive disk along the first guide path and on the rotating disk along the second guide path, and the first guide path and the second guide path are both arranged radially along the floating disk and intersect, so that the floating disk can rotate synchronously with the drive disk and the rotating disk.

[0010] Furthermore, the seat rotation assembly also includes a pressure plate for pressing the rotating disk onto the fixed disk, and ball bearing assemblies are provided between the fixed disk and the rotating disk, as well as between the rotating disk and the pressure plate; during the rotation of the rotating disk, the rotating disk and the ball bearing assemblies roll in cooperation.

[0011] Furthermore, the driving device includes a motor fixed to the fixed disk and an angle adjuster driven by the motor; the driving disk is disposed on the angle adjuster and rotates under the drive of the angle adjuster.

[0012] Furthermore, the rotating disk has a sliding bracket on the side facing the fixed disk, and the bottom of the sliding bracket has an elastic support part that abuts against the fixed disk.

[0013] Furthermore, the sliding bracket is a plurality of evenly spaced brackets distributed around the circumference of the rotating disk; and / or, the surface of the elastic support portion that abuts against the fixed disk is provided with a plurality of first grooves spaced apart, and each of the first grooves is arranged around the circumference of the rotating disk.

[0014] Furthermore, the floating disk is provided with a first slide groove and a second slide groove, and both the first slide groove and the second slide groove are provided with guide sliders; the guide sliders include a first slider fixed to the drive disk and slidably disposed in the first slide groove, and a second slider fixed to the rotating disk and slidably disposed in the second slide groove, the first slider and the first slide groove defining the first guide path, and the second slider and the second slide groove defining the second guide path.

[0015] Furthermore, both the first and second slides are composed of two elongated holes that are centrally symmetrical about the center of the floating disk. The first and second sliders are each two of the corresponding elongated holes. All four elongated holes extend radially along the floating disk and are evenly distributed around the circumference of the floating disk.

[0016] Furthermore, both the first and second slides are elongated holes that penetrate the plate of the floating disk; the guide slider includes a base and a slider body assembled on the base, and the top of the slider body is provided with a top plate; when the guide slider is assembled in the elongated hole, the base and the top plate are respectively blocked on both sides of the plate of the floating disk to restrict the slider body in the elongated hole.

[0017] Furthermore, both sides of the slider body are provided with elastic abutment portions, and the two elastic abutment portions abut against the inner walls of the two sides of the elongated hole respectively; and / or, the slider body is provided with a threaded insert, and the threaded insert is provided with a threaded hole for fixing the drive disk or the rotating disk.

[0018] Compared with related technologies, this application has the following advantages:

[0019] (1) The seat rotation assembly of this application adopts a transmission form of drive disc, floating disc and rotating disc. With the help of the guide sliding structure located on the radial side of the floating disc, the drive disc can drive the floating disc to rotate synchronously through the guide sliding structure between the drive disc and the floating disc under the drive device. The floating disc can drive the rotating disc to rotate synchronously through the guide sliding structure between the floating disc and the rotating disc. This can effectively improve the problems of jamming and play caused by the tooth meshing clearance in the gear transmission form. Moreover, since the first guide path and the second guide path are arranged at an intersection on two radial sides with a certain angle on the floating disc, the sliding action of the floating disc on the drive disc and the rotating disc can solve the problem of eccentric rotation transmission where the rotation axes of the drive disc and the rotating disc do not coincide, ensuring the smooth operation of the transmission. This provides a seat rotation drive solution that is conducive to improving the problem of transmission meshing clearance.

[0020] (2) The assembly is equipped with a pressure plate, which can reliably press the rotating disk onto the fixed disk. At the same time, a set of ball bearing assemblies are set on the upper and lower sides of the rotating disk, so that the rotating disk and the fixed disk, as well as the rotating disk and the pressure plate, are in the form of rolling fit. This can greatly reduce the friction of the rotating disk, so that the rotating disk can rotate smoothly on the fixed disk.

[0021] (3) The drive device adopts a combination of motor and angle adjuster, which not only facilitates drive control, but also the angle adjuster can achieve the effect of deceleration and torque increase, thus smoothly realizing the drive of the drive disk rotation.

[0022] (4) A sliding bracket is provided on one side of the bottom of the rotating disk. The sliding bracket can form a good support between the rotating disk and the fixed disk, avoiding the situation where the weight of the seat and the rotating disk is entirely borne by the first ball bearing assembly and the floating disk. This can greatly reduce the burden on the guide sliding structure between the drive disk, the floating disk and the rotating disk, as well as the first ball bearing assembly, thereby improving the service durability of the seat rotation assembly. An elastic support part is provided on the bottom of the sliding bracket, which can form a good elastic buffer effect to adapt to different load conditions whether there are passengers on the seat. Moreover, during the rotation of the rotating disk relative to the fixed disk, since the elastic support part and the upper surface of the fixed disk are in a sliding fit, the elastic contact of the elastic support part on the fixed disk also helps to reduce the friction between the sliding bracket and the fixed disk.

[0023] (5) Multiple sliding supports are evenly distributed at intervals at the bottom of the rotating disk, which can form multi-point support for the rotating disk and facilitate the formation of a more balanced and reliable support structure under the rotating disk. Multiple first grooves are machined at the bottom of the elastic support part of the sliding support, which can reduce the contact area between the elastic support part and the fixed disk. Moreover, the direction of each first groove is located in the circumferential direction of the rotating disk. During the rotation of the rotating disk relative to the fixed disk, the ribs between adjacent first grooves can slide smoothly along the circumferential direction of the rotating disk, which helps to further reduce the friction between the sliding support and the fixed disk. While meeting the support requirements of the rotating disk, it ensures the smoothness of the rotating disk's rotation.

[0024] (6) By setting two grooves on the floating disk and cooperating with two sets of guide sliders, the guiding and sliding purpose of the floating disk on the rotating disk and on the driving disk can be well realized, and the first and second guiding paths that intersect each other can be effectively defined. The setting of the guide sliders can not only achieve a fixed connection with the driving disk or the rotating disk, but also fit well into the corresponding grooves, thereby achieving the purpose of guiding and sliding.

[0025] (7) By opening four elongated holes on the floating disk, and after defining the length, direction and position of the elongated holes, mutually perpendicular grooves can be defined on the floating disk, so that the first guide path and the second guide path are vertically distributed. In this way, by using the cooperation and sliding of the floating disk on the first guide path and the second guide path, the problem of eccentric transmission between the drive disk and the rotating disk can be well overcome, and the purpose of synchronous rotation transmission between two rotating bodies with different axes can be well achieved.

[0026] (8) The guide slider is designed as a split form consisting of a base and a slider body. The base and slider body can be snapped together from both sides of the floating plate. The bottom plate of the base, which is larger than the width of the long hole, and the top plate of the slider body are used to limit the guide slider in the long hole, which can facilitate the assembly and setting of the guide slider in the long hole.

[0027] (9) By providing an elastic abutment part on the side of the slider body, and utilizing the abutment fit between the elastic abutment part and the inner wall of the elongated hole, the transmission gap is better avoided, and relative play between the floating plate and the drive plate, as well as between the rotating plate and the floating plate, is effectively prevented, which is conducive to further improving the driving smoothness and quietness of the seat rotation assembly. A threaded insert is provided in the slider body. Utilizing the threaded hole provided on the threaded insert, the guide slider can be easily fixed to the drive plate by the slider fastening screw, or fixed to the rotating plate by the connecting bolt, thereby improving the fixed stability of the guide slider.

[0028] Another object of this application is to provide a vehicle equipped with the seat rotation assembly described in this application. The vehicle of this application possesses the technical advantages of the aforementioned seat rotation assembly. Attached Figure Description

[0051] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0052] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0053] Furthermore, it should be stated in the description of this application that if terms such as "up," "down," "left," "right," "front," "rear," "inner," and "outer" appear, indicating orientation or positional relationships, they are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this application and for clarity and conciseness of expression, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this application. Taking the vehicle described in this application as an example, the directional terms such as "up," "down," "left," "right," "front," and "rear" used in the embodiments are defined based on the vehicle's vertical direction (also known as the height direction), horizontal direction (also known as the width direction), and front-back direction (also known as the length direction). "Inner" and "outer" are defined based on the outline of the corresponding component. For example, "inner" and "outer" are defined based on the vehicle's outline, with the side of the vehicle outline closer to the middle of the vehicle being "inner," and vice versa.

[0054] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joint," and "connector" should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances. The qualifying terms such as "first," "second," "A," "B," "C," and "D" appearing in the description of this application are merely for distinguishing similar features in different locations, attributions, or uses, in order to avoid ambiguity and confusion, and should not be construed as indicating or implying relative importance.

[0055] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0056] It is important to emphasize that in technologies related to electric rotating discs for vehicle seats, the electric rotating disc is often fixedly mounted to the vehicle frame or the slide rails for the seat's forward and backward movement. The seat is then fixed to the turntable of the electric rotating disc, which drives the seat to complete the rotation at a set angle. These electric rotating discs are complex in structure, heavy, and costly. The drive mechanism often uses a motor to drive a gear plate or rack. This type of structure has a certain amount of clearance in the gear mesh, resulting in a relatively large clearance in the rotational transmission. This causes issues such as jamming and play during seat rotation and steering, requiring an additional mechanism to eliminate the clearance. This further increases the manufacturing cost and weight of the electric rotating disc, and also makes the assembly of the entire mechanism quite complex.

[0057] Furthermore, because the seats are equipped with backrest angle adjustment mechanisms, heating devices, and detection devices to check whether someone is sitting in the seat, a certain number of electrical wires are routed out from the seats. The wiring harness composed of these wires needs to pass through the electric rotary table and connect to the vehicle's control system. The existing electric rotary table and its clearance elimination mechanism are already structurally complex to assemble, and they also need to perform rotational drive actions, making the wiring harness layout very difficult. Laying the wiring harness in a small and compact space also affects the assembly of the rotary table. Therefore, it is often necessary to reserve a long wiring harness and avoid related structures through detour wiring. This not only increases the cost of the wiring harness, but also easily leads to situations such as the wiring harness getting tangled with adjacent mechanisms or the wiring harness being broken.

[0058] In view of the above-mentioned problems in the related technologies, this application innovatively proposes a brand-new seat rotation assembly, providing a seat rotation drive solution that is beneficial to improving the transmission fit clearance problem.

[0059] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0060] The first aspect of this application provides a seat rotation assembly, which can be applied to scenarios where seats in vehicles need to rotate to accommodate different passenger orientations, and can also be applied to other types of seats that require rotation; an exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0061] Overall, the seat rotation assembly includes a fixed disk 1, a rotating disk 5 rotatably mounted on the fixed disk 1, a drive device 2 mounted on the fixed disk 1, and a drive disk 3 and a floating disk 4 connected to the drive device 2 and the rotating disk 5. The drive disk 3 is located in the center of the fixed disk 1 and can rotate under the drive of the drive device 2. The floating disk 4 is slidably mounted on the drive disk 3 along a first guide path and on the rotating disk 5 along a second guide path. Both the first and second guide paths are radially arranged and intersect the floating disk 4, so that the floating disk 4 can rotate synchronously with the drive disk 3 and the rotating disk 5.

[0062] It should be noted that the fixed plate 1, drive plate 3, floating plate 4, rotating plate 5, and pressure plate 6 in the car seat turntable are preferably arranged coaxially and assembled together in a stacked and fastened manner from bottom to top. Therefore, the rotating plate 5 and the fixed plate 1 are coaxial, and the rotating plate 5 rotates about the axes of the fixed plate 1 and the rotating plate 5. However, although the drive plate 3 is located in the middle of the fixed plate 1, the drive device 2 often uses an angle adjuster 21 of planetary gear or other gear transmission to reduce the speed of the drive plate 3. Due to the presence of gears, gear rings, and other meshing transmissions, the axis of rotation of the drive plate 3 may not be fixed and may be offset relative to the axis of the fixed plate 1, resulting in the rotation of the drive plate 3 being eccentric relative to the rotating plate 5. Even if the axis of the drive plate 3 does not shift during the transmission of the angle adjuster 21, assembly errors may still lead to eccentricity between the drive plate 3 and the rotating plate 5. Therefore, the drive plate 3 and the rotating plate 5 cannot be directly fixed together.

[0063] For the reasons mentioned above, the automotive seat turntable of this application adopts a transmission form of drive disc 3, floating disc 4, and rotating disc 5. With the help of the guide sliding structure located on the radial side of the floating disc 4, under the drive of the drive device 2, the drive disc 3 can drive the floating disc 4 to rotate synchronously through the guide sliding structure between the drive disc 3 and the floating disc 4. The floating disc 4 can then drive the rotating disc 5 to rotate synchronously through the guide sliding structure between the floating disc 4 and the rotating disc 5. This can effectively improve the problems of jamming and play caused by the tooth meshing clearance in the gear transmission form. Moreover, since the first guide path and the second guide path are arranged at an intersection on two radial sides with a certain angle on the floating disc 4, the sliding action of the floating disc 4 on the drive disc 3 and the rotating disc 5 can solve the problem of eccentric rotation transmission where the rotation axes of the drive disc 3 and the rotating disc 5 do not coincide, ensuring smooth transmission. This provides a seat rotation drive solution that is beneficial to improving the problem of transmission meshing clearance.

[0064] It should also be noted that, based on the overall design concept described above, the technical solution of this application can adopt various different specific implementation structures, forms, or configuration sequences. For example, the aforementioned drive device 2 can be in the form of a motor 20 combined with an angle adjuster 21, or a slow-speed motor can directly drive the drive disk 3 to rotate; the floating disk 4 can be designed as a disc, or as a support in the form of a triangle, quadrilateral, or other shapes; the specific arrangement sequence and assembly method of the fixed disk 1, drive device 2, drive disk 3, floating disk 4, and rotating disk 5 can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not covered in the above overall setup, reasonable and flexible designs can be made by referring to mature setup methods in the field and the actual situation during implementation, which will not be elaborated here. The specific implementation scheme described below in this embodiment is only one of the many solutions that can be formed by the various combinations and variations described above. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the various solutions that can be formed by the combinations and variations of the above specific forms, as well as the specific implementation scheme of this embodiment, are all within the protection scope of this application.

[0065] Specifically, such as Figure 3 and Figure 4 As shown, in some preferred exemplary embodiments, the seat rotation assembly further includes a pressure plate 6 for pressing the rotating disk 5 onto the fixed disk 1, and ball bearing assemblies are provided between the fixed disk 1 and the rotating disk 5, as well as between the rotating disk 5 and the pressure plate 6; during the rotation of the rotating disk 5, the rotating disk 5 rolls in contact with the ball bearing assemblies. By configuring the pressure plate 6 on the assembly, the rotating disk 5 can be reliably pressed onto the fixed disk 1. Simultaneously, a set of ball bearing assemblies is provided on the upper and lower sides of the rotating disk 5, ensuring a rolling contact between the rotating disk 5 and the fixed disk 1, as well as between the rotating disk 5 and the pressure plate 6. This significantly reduces the frictional force during the rotation of the rotating disk 5, allowing the rotating disk 5 to rotate smoothly on the fixed disk 1.

[0066] In practical implementation, the fixed plate 1, rotating plate 5, and pressure plate 6 can all be disc-shaped. A wire hole 102 can be opened in the middle of the fixed plate 1, a through hole 500 can be opened in the middle of the rotating plate 5, and a clearance hole 600 is formed in the middle of the annular pressure plate 6. The wiring harness 9 connecting the seat and the vehicle control system can be laid by passing through the wire hole 102, the through hole 500, and the clearance hole 600 in sequence. In order to facilitate the installation of the seat on the rotating plate 5, an upwardly protruding mounting platform 506 can be formed in the middle of the rotating plate 5. The mounting platform 506 has a mounting hole 507. The seat fixing bolt 52 passes through the mounting hole 507 from the bottom of the rotating plate 5 and screws it onto the seat to realize the fixed connection between the rotating plate 5 and the seat. Furthermore, the pressure plate 6 can be designed as an annular shape, allowing it to be press-fitted onto the edge of the rotating disk 5 located around the mounting platform 506. Multiple press-fit holes 601 are spaced apart on the edge of the pressure plate 6. Pressure plate fastening bolts 61, passing through the press-fit holes 601 and through the fixed disk 1, are screwed onto the nut 11 at the bottom of the fixed disk 1, thus securely mounting the pressure plate 6 onto the fixed disk 1. For the specific structural form of the ball bearing assembly, existing ball bearing structures can be referenced for design. In this embodiment, the ball bearing assembly includes an annular cage 801 and multiple steel balls 800 evenly distributed on the cage 801. To facilitate the assembly of the ball bearing assembly, a first lower slide rail 101 can be formed on the upper surface of the fixed disk 1, and a first upper slide rail 501 can be formed on the lower surface of the rotating disk 5. The first ball bearing assembly 8a can then be assembled into the ball bearing slide rail defined by the first lower slide rail 101 and the first upper slide rail 501. Similarly, a second lower slide rail 502 can be formed on the upper surface of the rotating disk 5, and a second upper slide rail 602 can be formed on the lower surface of the pressure plate 6. The second ball bearing assembly 8b can then be assembled into the ball bearing slide rail defined by the second lower slide rail 502 and the second upper slide rail 602.

[0067] As mentioned above, there are various drive structure options available for the drive device 2; in this embodiment, such as Figure 5 As shown, in some preferred exemplary embodiments, the drive device 2 includes a motor 20 fixed to the fixed disk 1 and an angle adjuster 21 driven by the motor 20; the motor 20 is driven by the angle adjuster 21 via the angle adjuster linkage 200; the drive disk 3 is mounted on the angle adjuster 21 and rotates under the drive of the angle adjuster 21. The drive device 2 uses a combination of motor 20 and angle adjuster 21, which not only facilitates drive control, but also allows the angle adjuster 21 to achieve the effect of deceleration and torque increase, thereby smoothly driving the rotation of the drive disk 3.

[0068] Of course, a center hole 100 can be made at the center of the fixed plate 1, and the adjusting rod 200 on the motor 20 can pass through the bottom of the fixed plate 1 into the interior of the car seat turntable and connect with the adjusting device 21. At the same time, a motor positioning hole 103 can be made on the fixed plate 1, which, together with the positioning pin and other structures on the motor 20, enables the motor 20 to be quickly positioned and installed on the fixed plate 1.

[0069] Continue as Figure 4 As shown, in some preferred exemplary embodiments, the rotating disk 5 has a sliding bracket 53 on the side facing the fixed disk 1, and the bottom of the sliding bracket 53 has an elastic support portion 532 that abuts against the fixed disk 1. The sliding bracket 53, located on the bottom side of the rotating disk 5, provides good support between the rotating disk 5 and the fixed disk 1, preventing the weight of the seat and rotating disk 5 from being entirely borne by the first ball bearing assembly 8a and the floating disk 4. This significantly reduces the burden on the guide sliding structure between the drive disk 3, the floating disk 4, and the rotating disk 5, as well as the first ball bearing assembly 8a, thereby improving the durability of the seat rotation assembly. The elastic support portion 532 on the bottom of the sliding bracket 53 provides a good elastic cushioning effect, adapting to different load conditions, whether or not a passenger is on the seat. Furthermore, during the rotation of the rotating disk 5 relative to the fixed disk 1, the elastic abutment of the elastic support portion 532 against the fixed disk 1, due to the sliding fit between the elastic support portion 532 and the upper surface of the fixed disk 1, also helps reduce the friction between the sliding bracket 53 and the fixed disk 1.

[0070] Of course, the aforementioned sliding bracket 53 can also be in the form of a bracket or a solid structure, and the material can be flexibly selected. In this embodiment, the sliding bracket 53 is preferably a solid rubber block, and a certain number of weight-reducing cavity structures are formed on the sliding bracket 53. Combined with... Figure 6 As shown, the sliding bracket 53 of this embodiment has a screw hole 530 on its top. This screw hole 530 can be set on the insert embedded in the sliding bracket 53 to improve the connection strength. By screwing the bracket mounting screw 54, which passes through the rotating disk 5, into the screw hole 530, the sliding bracket 53 can be fixedly mounted on the rotating disk 5. At the same time, a number of positioning posts 531 can be set on the top of the sliding bracket 53, and corresponding positioning holes can be set on the rotating disk 5. When the sliding bracket 53 is installed on the rotating disk 5, the positioning posts 531 can be inserted into the corresponding positioning holes. The positioning posts 531 and the bracket mounting screw 54 cooperate to ensure the firmness of the sliding bracket 53 on the rotating disk 5.

[0071] For the elastic support part 532 at the bottom of the sliding bracket 53, a material with elastic deformation properties can be directly used to achieve its elasticity; or a first deformation cavity 534 can be designed at the bottom of the sliding bracket 53, so that the elastic support part 532 is a downward arched plate, and the elastic support capacity of the elastic support part 532 can be obtained or improved by utilizing its own arched structure.

[0072] Based on the above configuration of the sliding bracket 53, it remains as follows: Figure 4 As shown, in some preferred exemplary embodiments, the sliding brackets 53 are a plurality of evenly spaced along the circumference of the rotating disk 5; preferably, a plurality of first grooves 533 are arranged at intervals on the surface of the elastic support portion 532 that abuts against the fixed disk 1, and each of the first grooves 533 is arranged along the circumference of the rotating disk 5. The evenly spaced distribution of multiple sliding brackets 53 at the bottom of the rotating disk 5 forms multi-point support for the rotating disk 5, which facilitates a more balanced and reliable support structure below the rotating disk 5. The machining of multiple first grooves 533 at the bottom of the elastic support portion 532 of the sliding bracket 53 reduces the contact area between the elastic support portion 532 and the fixed disk 1. Furthermore, since the orientation of each first groove 533 is along the circumference of the rotating disk 5, during the rotation of the rotating disk 5 relative to the fixed disk 1, the ribs between adjacent first grooves 533 can smoothly slide along the circumference of the rotating disk 5, further reducing the friction between the sliding brackets 53 and the fixed disk 1, thus ensuring the smooth rotation of the rotating disk 5 while meeting the support requirements of the rotating disk 5.

[0073] For the specific configuration of the floating disk 4, there are naturally many different structural options available; for example, the floating disk 4 can be in the form of a plate or a frame structure; there are also various ways to achieve the guiding and sliding between the floating disk 4 and the driving disk 3, and between the floating disk 4 and the rotating disk 5, such as designing a slide rail structure between the floating disk 4 and the driving disk 3, or opening a slide track on the rotating disk 5, etc. In this embodiment, as... Figure 5 and combined Figure 7 As shown, the floating disk 4 adopts a frame structure similar to a square, and a wire hole 400 is formed in the middle of the floating disk 4 for the wire harness 9 to pass through.

[0074] Meanwhile, the floating disk 4 is provided with a first slide groove 401 and a second slide groove 402, and each of the first slide groove 401 and the second slide groove 402 is provided with a guide slider 7. Specifically, the guide slider 7 includes a first slider 7a fixed to the drive disk 3 and slidably disposed in the first slide groove 401, and a second slider 7b fixed to the rotating disk 5 and slidably disposed in the second slide groove 402. The first slider 7a and the first slide groove 401 define a first guide path, and the second slider 7b and the second slide groove 402 define a second guide path. By providing two slide grooves on the floating disk 4 and cooperating with two sets of guide sliders 7, the guiding and sliding purpose of the floating disk 4 on the rotating disk 5 and on the drive disk 3 can be well realized, and the intersecting first and second guide paths can be effectively defined. The setting of the guide slider 7 can achieve fixed connection with the drive disk 3 or the rotating disk 5, and can also be well assembled into the corresponding slide groove, thereby realizing the purpose of guiding and sliding.

[0075] Continue as Figure 5 and Figure 7 As shown, in some preferred exemplary embodiments, the first groove 401 and the second groove 402 are both composed of two elongated holes that are centrally symmetrical about the center of the floating disk 4. Therefore, four elongated holes need to be designed on the floating disk 4. Preferably, the four elongated holes can be respectively opened at the four corners of the floating disk 4. The corners of the floating disk 4 can be designed to protrude outward along the radial direction of the floating disk 4 to increase the space for opening the elongated holes. Correspondingly, the first slider 7a and the second slider 7b are each two respectively provided in the corresponding elongated holes; the four elongated holes are all arranged to extend radially along the floating disk 4, and the four elongated holes are evenly distributed in the circumferential direction of the floating disk 4. By opening four elongated holes on the floating disk 4, and defining the length, direction, and position of each elongated hole according to the above requirements, two mutually perpendicular sliding grooves can be defined on the floating disk 4, thereby making the first guide path and the second guide path perpendicularly distributed. In this way, by using the cooperation and sliding of the floating disk 4 on the first guide path and the second guide path, the eccentric transmission problem of the drive disk 3 relative to the rotating disk 5 can be well overcome, and a good synchronous rotation transmission purpose can be achieved between two rotating bodies with different axes.

[0076] Regarding the specific configuration of the guide slider 7, there are naturally several different structural options available; for example, a single-unit structure or a split structure can be used. In this embodiment, as... Figure 7As shown, since both the first groove 401 and the second groove 402 are elongated holes that penetrate the plate of the floating disk 4, the guide slider 7 preferably adopts a split structure. Specifically, the guide slider 7 in this embodiment includes a base 70 and a slider body 71 assembled on the base 70, and the top of the slider body 71 is provided with a top plate 710. When the guide slider 7 is assembled in the elongated hole, the base 70 and the top plate 710 are respectively positioned on both sides of the plate of the floating disk 4 to restrict the slider body 71 in the elongated hole. Since both the first slide groove 401 and the second slide groove 402 are constructed as elongated holes, the guide slider 7 is designed as a separate unit consisting of a base 70 and a slider body 71. The base 70 and the slider body 71 can be fastened together from both sides of the floating disk 4. The bottom plate 700 of the base 70, which is slightly larger than the width of the elongated hole, and the top plate 710 of the top of the slider body 71 are used to limit the guide slider 7 in the elongated hole, which can facilitate the assembly and setting of the guide slider 7 in the elongated hole.

[0077] In the specific design, a side plate 701 can be designed on each side of the base plate 700, and a snap-fit ​​window 702 can be opened on the side plate 701. Correspondingly, a snap-fit ​​head 712 can be set on the slider body 71. The slider body 71 is inserted between the two side plates 701, and the snap-fit ​​head 712 is snapped into the snap-fit ​​window 702 on the corresponding side to realize the quick snap-fit ​​assembly between the slider body 71 and the base 70.

[0078] Meanwhile, to meet the need for the guide slider 7 to be fixed to the drive disk 3 or the rotating disk 5, a threaded insert 72 can be embedded in the slider body 71, and a threaded hole 720 for fixing the drive disk 3 or the rotating disk 5 can be opened on the threaded insert 72. By setting the threaded insert 72 in the slider body 71 and using the threaded hole 720 on the threaded insert 72, the guide slider 7 can be easily fixed to the drive disk 3 by the slider fastening screw 31, or fixed to the rotating disk 5 by the connecting bolt 51, thereby improving the fixing stability of the guide slider 7.

[0079] Furthermore, while utilizing the threaded hole 720 for screw connection, a positioning structure can be designed between the guide slider 7 and the rotating disk 5, or between the guide slider 7 and the drive disk 3. Taking the installation of the second slider 7b on the rotating disk 5 as an example, as follows... Figure 4 and Figure 5 , Figure 7As shown, the rotating disk 5 has a through hole 503, and two positioning notches 504 are respectively opened on the side of the through hole 503. The connecting bolt 51 is inserted into the through hole 503 and screwed into the threaded hole 720 on the second slider 7b. The threaded insert 72 is also provided with two positioning protrusions 721 located on both sides of the threaded hole 720. When the second slider 7b is set at the position on the bottom of the rotating disk 5 corresponding to the through hole 503, the two positioning protrusions 721 are respectively inserted into the two positioning notches 504 at the through hole 503, realizing the quick positioning of the second slider 7b on the rotating disk 5. Then the connecting bolt 51 is screwed into the threaded hole 720 to realize the reliable fixation of the second slider 7b on the rotating disk 5. The cooperation of the positioning protrusions 721 and the positioning notches 504 can also prevent the second slider 7b from rotating on the rotating disk 5. The placement of the first slider 7a on the drive disk 3 can be referenced to the placement of the second slider 7b on the rotating disk 5. For the case where the first slider 7a is positioned at the top of the drive disk 3, a groove 302 can be formed on the drive disk 3 at the location of the first slider 7a, allowing the first slider 7a to be more easily positioned correctly on the drive disk 3. Then, a slider fastening screw 31, passing through the drive disk 3 from below, is used to fasten the first slider 7a to the drive disk 3. Furthermore, since the slider fastening screw 31 may protrude upwards after passing through the first slider 7a, potentially interfering with the rotating disk 5 located above, a avoidance hole 505 can be made at the corresponding position on the rotating disk 5 to avoid the slider fastening screw 31.

[0080] Continue as Figure 7 As shown, in some preferred exemplary embodiments, in order to achieve a good sliding fit between the guide slider 7 and the inner walls of the elongated hole on both sides of the floating disk 4, the slider body 71 of this embodiment is provided with elastic abutment portions 713 on both sides, and the two elastic abutment portions 713 abut against the inner walls of the elongated hole on both sides respectively. By providing elastic abutment portions 713 on the side of the slider body 71, and utilizing the abutment fit between the elastic abutment portions 713 and the inner walls of the elongated hole, the occurrence of transmission clearance is better avoided; this not only satisfies the guiding sliding requirements of the guide slider 7 in the elongated hole, but also effectively avoids relative play between the floating disk 4 and the drive disk 3, and between the rotating disk 5 and the floating disk 4, during the synchronous rotation of the floating disk 4 with the drive disk 3 and the rotating disk 5, which is beneficial to further improve the driving smoothness and quietness of the seat rotation assembly.

[0081] The specific configuration of the elastic abutment portion 713 can be designed with reference to the configuration of the elastic support portion 532 on the sliding bracket 53. Specifically, the slider body 71 can be made of a material with elastic deformation properties to achieve its elasticity, or a second deformation cavity 711 can be designed on the side of the slider body 71, making the elastic abutment portion 713 an outwardly arched plate shape, and using the arched structure of the elastic abutment portion 713 itself to obtain or improve the elastic support and abutment performance of the elastic abutment portion 713.

[0082] Simultaneously, multiple second grooves 714 can be machined on the elastic abutment portion 713, and the direction of each second groove 714 is consistent with the arrangement direction of the elongated hole (which is also the sliding direction of the guide slider 7); that is, multiple ribs formed between adjacent second grooves 714 are formed on the surface of the elastic abutment portion 713. The elastic abutment portion 713 abuts against the inner wall of the side of the elongated hole through these ribs, realizing the sliding fit between the elastic abutment portion 713 and the inner wall of the elongated hole. The above-mentioned structural form can reduce the contact area between the elastic abutment portion 713 and the inner wall of the elongated hole, and the direction of each second groove 714 is consistent with the sliding direction of the guide slider 7. During the process of the guide slider 7 sliding in the elongated hole, the ribs between adjacent second grooves 714 can slide smoothly on the inner wall of the elongated hole, which can further reduce the friction between the guide slider 7 and the elongated hole, making the guiding sliding of the floating disk 4 on the drive disk 3 and the guiding sliding of the floating disk 4 on the rotating disk 5 smoother.

[0083] In addition, this application also provides a good solution to the problem of difficulty in laying the seat wiring harness 9 in the car seat turntable mentioned above.

[0084] Continue as shown in the figure Figures 1 to 5 As shown, the seat rotation assembly includes a fixed plate 1, a drive plate 3, and a rotating plate 5 arranged sequentially from bottom to top. The rotating plate 5 is rotatably mounted on the fixed plate 1 and is used to support the seat. A through hole 500 is provided in the center of the rotating plate 5. The fixed plate 1 has a wire hole 102 and a drive device 2 for driving the drive plate 3 to rotate. The drive plate 3 is rotatably connected to the rotating plate 5 to drive the rotating plate 5 to rotate. Simultaneously, the drive plate 3 has a power input section 3a in the center for connecting the drive device 2. Wiring holes 300, distributed in a semi-encircling shape around the power input section 3a, are provided on the plate of the drive plate 3. A wire harness 9 from the seat passes through the through hole 500, the wiring hole 300, and the wire hole 102 sequentially to connect to the outside.

[0085] Based on the overall design concept described above, by opening a wire-passing hole 102, a wiring hole 300, and a through hole 500 on the fixed plate 1, drive plate 3, and rotating plate 5 respectively, the seat wiring harness 9 can be threaded and arranged. This allows the wiring harness 9 to be smoothly led to the vehicle floor under the seat, and then connected to the vehicle's control system to meet the needs of seat back angle adjustment, seat heating, and related testing. Since the power input section 3a in the middle of the drive plate 3 needs to connect to the drive unit 2, and the drive plate 3 needs to rotate 180° to achieve forward and backward steering of the seat via the rotating plate 5, the wiring hole 300 on the drive plate 3 is designed as a semi-enclosed shape. This allows the wiring harness 9 to pass through without interfering with the rotation of the drive plate 3. During the rotation of the drive plate 3, the wiring harness 9 can be located at different positions in the wiring hole 300, which always avoids obstructing the wiring harness 9. This prevents problems such as difficulty in wiring harness 9 arrangement and easy entanglement with adjacent mechanisms, thereby improving the arrangement conditions of the seat wiring harness 9 in the seat rotation assembly.

[0086] Specifically, such as Figure 5 As shown, in some preferred exemplary embodiments, the fixed plate 1 has a central hole 100. The drive device 2 includes a motor 20 fixed to the bottom of the fixed plate 1 and an adjuster 21 located above the central hole 100. An adjuster linkage 200 on the motor 20 passes through the central hole 100 and connects to the adjuster 21. The drive plate 3 is mounted on the adjuster 21 and rotates under the drive of the adjuster 21. The drive device 2 uses a combination of the motor 20 and the adjuster 21, which not only facilitates drive control but also allows the adjuster 21 to achieve a speed reduction and torque increase effect, thereby smoothly driving the rotation of the drive plate 3. By opening a central hole 100 at the center of the fixed plate 1, it is convenient to arrange the adjuster linkage 200 and to easily place the adjuster 21 inside the seat rotation assembly for assembly and connection with the drive plate 3.

[0087] Given that the edge of the wiring hole 300 may rub against the wire harness 9 during the rotation of the drive disk 3, preferably, a flange structure can be designed on the plate of the drive disk 3; specifically, a flange 301 is formed on the edge of the wiring hole 300. Since the wire harness 9 passes through the wiring hole 300, there is a possibility that the wire harness 9 and the edge of the wiring hole 300 may come into contact during the rotation of the drive disk 3; by providing a flange 301 on the edge of the wiring hole 300, the presence of sharp edges and burrs on the edge of the wiring hole 300 can be avoided, thereby preventing the wire harness 9 from being damaged due to sharp edges and burrs rubbing against it.

[0088] Based on the aforementioned arrangement of the first slider 7a on the drive disk 3, preferably, as follows: Figure 5As shown, in some preferred exemplary embodiments, the drive disk 3 is provided with two transmission output parts 3b for respectively fixing the two first sliders 7a. These two transmission output parts 3b are located at the edge of the drive disk 3 and are centrally symmetrically distributed about the center of the drive disk 3. Furthermore, the transmission output parts 3b protrude outwards along the radial direction of the drive disk 3. Given that the size of the drive disk 3 should not be too large to reduce the space occupied by the seat rotation assembly and to save materials, placing the two transmission output parts 3b for power output at the outwardly protruding position on the edge of the drive disk 3 can effectively increase the output torque of the drive disk 3, thereby achieving positional matching with the two corresponding first sliding grooves 401 on the floating disk 4, which can well meet the setting requirements of the two first sliders 7a. Of course, the aforementioned recess 302 for mounting and positioning the first sliders 7a can simply be provided on the transmission output parts 3b.

[0089] Meanwhile, as mentioned above, in some preferred exemplary embodiments, the floating disk 4 is rectangular, with a wire hole 400 formed in the hollow center of the floating disk 4; the four corners of the floating disk 4 protrude outwards radially, and four elongated holes are respectively located at the four corners of the floating disk 4. The rectangular structure of the floating disk 4 can effectively save material consumption and can well meet the arrangement requirements of the four elongated holes. The outward protrusion of the four corners of the floating disk 4 can meet the length requirements of the elongated holes within the relatively small overall size of the floating disk 4, and can be adapted to the assembly positions of the first slider 7a located on the drive disk 3 and the second slider 7b located on the rotating disk 5.

[0090] Furthermore, combined Figure 8 and Figure 9 As shown, in some preferred exemplary embodiments, the floating disk 4 has a sliding sleeve 41 on its plate. The sliding sleeve 41 is clamped at the edge of the wire hole 400 and forms elastic support between the floating disk 4 and the rotating disk 5, and between the floating disk 4 and the drive disk 3. The number of sliding sleeves 41 can be flexibly selected. In this embodiment, one sliding sleeve 41 is provided at the inner edge of the wire hole 400 at each of the four corners of the floating disk 4. Adding sliding sleeves 41 to the floating disk 4 can form reliable isolation support in the narrow space between the floating disk 4 and the rotating disk 5, and between the floating disk 4 and the drive disk 3, avoiding direct rubbing between the floating disk 4 and the rotating disk 5, or between the floating disk 4 and the drive disk 3. The sliding sleeve 41 adopts an elastic support method, which can meet the situation where the position of the rotating disk 5 and the floating disk 4 fluctuates due to changes in the weight of the seat, and can produce a certain buffering effect. There are, of course, many ways to achieve the elastic support of the sliding sleeve 41; for example, the sliding sleeve 41 can be made of elastic materials such as rubber, or arched elastic deformation structures can be set at the top and bottom of the sliding sleeve 41 respectively.

[0091] Based on the above exemplary embodiments, as a preferred combination of the exemplary solutions, refer to Figures 1 to 9 As shown, the overall structure and working principle of the seat rotation assembly in this embodiment are as follows:

[0092] The drive disc 3 and the rotating disc 5 in the seat rotation assembly are eccentric transmission structures, and their output rotation is eccentric rotation. The eccentric rotation of the seat affects the riding experience. Therefore, by sliding the floating disc 4 between the two with an eccentric amount, the drive disc 3 can smoothly drive the rotating disc 5 to rotate synchronously, so as to support the seat to complete a 180° turn.

[0093] In the sliding structure design of the floating disk 4, the elongated holes at the four corners of the floating disk 4 form a groove, and each groove is equipped with a guide slider 7. The first slider 7a is fixedly connected to the drive disk 3, and the second slider 7b is fixedly connected to the rotating disk 5, allowing the floating disk 4 to slide on mutually perpendicular guide paths. Through the power transmission of the floating disk 4, the sliding of the floating disk 4 absorbs the eccentricity of the rotation, and synchronous rotation transmission can be well achieved between the drive disk 3 and the rotating disk 5 to overcome the eccentricity problem. At the same time, with the help of the elastic abutment part 713 designed on the side of the guide slider 7, the clearance play problem in the transmission process can be well improved.

[0094] Furthermore, thanks to the semi-enclosed wiring hole 300 designed on the drive disc 3, the wiring harness 9 can be easily routed through the entire seat rotation assembly, and the wiring hole 300 avoids the wiring harness 9 during the rotation of the drive disc 3. Figure 8 and Figure 10 and Figure 11 As shown, when the drive disk 3 drives the floating disk 4 and the rotating disk 5 from... Figure 8 The original position shown is rotated to Figure 10 At the 90° position shown, the wire harness 9 switches from one end of the wiring hole 300 to the middle of the wiring hole 300. When the drive disk 3 drives the floating disk 4 and the rotating disk 5 from... Figure 10 Rotate to the 90° position shown Figure 11 At the 180° position shown, the wiring harness 9 switches from the middle of the wiring hole 300 to the other end of the wiring hole 300. Throughout this process, the wiring harness 9 does not need to move; instead, the semi-circular clearance channel provided by the wiring hole 300 ensures perfect clearance of the wiring harness 9 during the seat rotation assembly's movement. Therefore, the seat rotation assembly of this application avoids the problem of the wiring harness 9 being twisted, while also being simple to arrange and compatible with the arrangement needs of various wiring harnesses 9 for seats. The length of the wiring harness 9 does not need to be increased or detoured, reducing the configuration cost of the wiring harness 9.

[0095] In summary, the seat rotation assembly of this embodiment adopts a transmission form of drive disk 3, floating disk 4, and rotating disk 5. With the help of the guide sliding structure located on the radial side of floating disk 4, under the drive of drive device 2, drive disk 3 can drive floating disk 4 to rotate synchronously through the guide sliding structure between drive disk 3 and floating disk 4. Floating disk 4 can then drive rotating disk 5 to rotate synchronously through the guide sliding structure between floating disk 4 and rotating disk 5. This effectively improves the problems of jamming and play caused by tooth meshing clearance in gear transmission. Moreover, since the first guide path and the second guide path are arranged at an intersection on two radial sides with a certain angle on floating disk 4, the sliding action of floating disk 4 on drive disk 3 and rotating disk 5 can solve the problem of eccentric rotation transmission where the rotation axes of drive disk 3 and rotating disk 5 do not coincide, ensuring smooth transmission. Thus, a seat rotation drive solution that is beneficial to improving the problem of transmission meshing clearance is provided.

[0096] Furthermore, in this embodiment, the seat rotation assembly has a wire hole 102, a wiring hole 300, and a through hole 500 respectively on the fixed plate 1, the drive plate 3, and the rotating plate 5, allowing the seat wiring harness 9 to be threaded and arranged. The wiring harness 9 can be smoothly led to the vehicle floor under the seat and then connected to the vehicle's control system to meet the needs of seat back angle adjustment, seat heating, and related detection. Since the power input part 3a in the middle of the drive plate 3 needs to be connected to the drive device 2, and the drive plate 3 needs to rotate 180° to meet the need for the seat to be turned forward and backward by the rotating plate 5, the wiring hole 300 on the drive plate 3 is designed as a semi-enclosed shape. While allowing the wiring harness 9 to pass through, the wiring harness 9 will not interfere with the rotation of the drive plate 3. During the rotation of the drive plate 3, the wiring harness 9 can be located at different positions in the wiring hole 300. The wiring hole 300 can always avoid the wiring harness 9, avoiding problems such as difficulty in arranging the wiring harness 9 and easy entanglement of the wiring harness 9 with adjacent mechanisms, thereby improving the arrangement conditions of the seat wiring harness 9 in the seat rotation assembly. Furthermore, the drive unit 2 adopts a combination of motor 20 and angle adjuster 21, which not only facilitates drive control, but also allows the angle adjuster 21 to achieve the effect of deceleration and torque increase, thereby smoothly driving the rotation of the drive disk 3. By opening a center hole 100 at the center of the fixed disk 1, it is convenient to pass through the motor 20 and the angle adjuster connecting rod 200, and the angle adjuster 21 can be easily installed inside the seat rotation assembly for assembly and connection with the drive disk 3.

[0097] An embodiment of the second aspect of this application provides a vehicle equipped with the seat rotation assembly provided in Embodiment 1; therefore, the vehicle possesses the technical advantages of the aforementioned seat rotation assembly.

[0098] By configuring the seat rotation assembly of this application on the vehicle, the eccentric transmission problem in the seat rotation assembly is solved by adopting the bidirectional sliding structure of the floating disk 4, enabling the seat rotation assembly to achieve synchronous rotation output; the waist-shaped hole designed on the drive disk 3, that is, the semi-enclosed wiring hole 300, allows the seat wiring harness 9 to pass through from top to bottom and connect to the vehicle control system. When the seat rotates, the wiring hole 300 rotates around the wiring harness 9, avoiding the problem of wire twisting. The structure is simple to assemble, with fewer parts and lower cost. The arrangement of the wiring harness 9 does not affect the rotation of the seat rotation assembly. The seat rotation assembly is supplied as a separate whole and has good compatibility and versatility.
