Description

Technical Field

[0001] The present application relates to the technical field of vehicle seats, and in particular to a seat rotation assembly and a vehicle. Background Art

[0002] In order to enrich the riding modes of the car cabin, many models will be equipped with rotating seats, so that the seats can be rotated 90° to welcome guests and view the scenery, and the seats can be rotated 180° to communicate face-to-face with passengers in the back.

[0003] In related technologies, an electric rotating plate is often used to install seats. The electric rotating plate is installed on the vehicle body or the slide rail for the seat to move forward and backward, and then the seat is fixed to the electric rotating plate. The electric rotating plate drives the seat to complete the rotation movement of the set angle.

[0004] However, the above-mentioned electric turntable has a complex turntable structure, heavy weight and high cost, and the driving structure mostly adopts a structure in which a motor drives a gear to drive a tooth plate or a rack; but this structure has a certain tooth matching gap, so the rotation transmission matching gap is large, resulting in jamming and looseness during the rotation and steering of the seat. An additional set of gap elimination mechanisms needs to be added, resulting in a high manufacturing cost and increased weight of the electric turntable, and the assembly of the entire mechanism is also relatively complicated. Summary of the Invention

[0005] In view of this, the present application aims to propose a seat rotation assembly to provide a seat rotation drive solution that is conducive to improving the transmission fit clearance problem.

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

[0008] It includes a fixed plate, a rotating plate rotatably arranged on the fixed plate, a driving device arranged on the fixed plate, and a driving plate and a floating plate transmission-connected between the driving device and the rotating plate;

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

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

[0011] Furthermore, the driving device includes a motor fixedly connected to the fixed disk, and a recliner transmission-connected to the motor; the driving disk is provided on the recliner and rotates under the transmission of the recliner.

[0012] Furthermore, a sliding bracket is provided on a side of the rotating disk facing the fixed disk, and an elastic supporting portion that abuts against the fixed disk is provided at the bottom of the sliding bracket.

[0013] Furthermore, the sliding brackets are multiple and evenly spaced around the circumference of the rotating disk; and / or, the surface where the elastic support portion abuts the fixed disk has multiple first grooves spaced apart, and each of the first grooves is arranged along the circumference of the rotating disk.

[0014] Furthermore, a first slide groove and a second slide groove are provided on the floating plate, and a guide slider is provided in the first slide groove and the second slide groove; the guide slider includes a first slider fixedly connected to the driving plate and slidably set in the first slide groove, and a second slider fixedly connected to the rotating plate and slidably set in the second slide groove, the first slider and the first slide groove define the first guide path, and the second slider and the second slide groove define the second guide path.

[0015] Furthermore, the first slide groove and the second slide groove are each composed of two long holes that are centrally symmetrical about the center of the floating plate, and the first slider and the second slider are each two respectively arranged in the corresponding long holes; the four long holes are all extended along the radial direction of the floating plate, and the four long holes are evenly spaced in the circumferential direction of the floating plate.

[0016] Furthermore, the first slide groove and the second slide groove are both elongated holes set through the plate body of the floating plate; the guide slider includes a base and a slider body assembled on the base, and a top plate is provided on the top of the slider body; 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 body of the floating plate to confine the slider body in the elongated hole.

[0017] Furthermore, elastic abutment parts are provided on both sides of the slider body, and the two elastic abutment parts respectively abut on the inner walls on both sides of the elongated hole; and / or, a threaded insert is embedded in the slider body, and a threaded hole is provided on the threaded insert for fixing the driving disk or the rotating disk.

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

[0019] (1) The seat rotation assembly of the present application adopts a transmission form of a driving plate, a floating plate and a rotating plate. With the help of a guide sliding structure located on the radial direction of the floating plate, under the drive of the driving device, the driving plate can drive the floating plate to rotate synchronously through the guide sliding structure between the driving plate and the floating plate, and the floating plate can drive the rotating plate to rotate synchronously through the guide sliding structure between the floating plate and the rotating plate, thereby effectively improving the problems of jamming and looseness caused by the tooth matching gap in the gear transmission form; moreover, since the first guide path and the second guide path are arranged crosswise and located on two radial directions with a certain angle on the floating plate, with the help of the sliding action of the floating plate on the driving plate and the rotating plate, the eccentric rotation transmission problem in which the rotation axes of the driving plate and the rotating plate do not coincide can be solved, thereby ensuring the smooth progress of the transmission, thereby providing a seat rotation drive solution that is conducive to improving the transmission matching gap problem.

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

[0021] (3) The driving device adopts the combination of motor and angle adjuster, which is not only convenient for driving control, but also the angle adjuster can achieve the effect of deceleration and torque increase, thereby smoothly realizing the driving of the driving disk to rotate.

[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, thereby avoiding the situation where the weight of the seat and the rotating disk is entirely borne by the first ball assembly and the floating disk. This can greatly reduce the burden on the guide sliding structure between the driving disk, the floating disk and the rotating disk, and the first ball assembly, thereby improving the durability of the seat rotation assembly. An elastic support portion is provided on the bottom of the sliding bracket to form a good elastic buffering effect, which can adapt to different load conditions of whether there are passengers on the seat. Moreover, during the rotation of the rotating disk relative to the fixed disk, since the elastic support portion and the upper surface of the fixed disk are in a sliding fit, the elastic abutment of the elastic support portion on the fixed disk also helps to reduce the friction between the sliding bracket and the fixed disk.

[0023] (5) Multiple sliding brackets are evenly spaced at the bottom of the rotating disk to form multi-point support for the rotating disk, which is conducive to forming a more balanced and reliable support structure under the rotating disk. Multiple first grooves are processed at the bottom of the elastic support part of the sliding bracket to 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 circumference of the rotating disk, which helps to further reduce the friction between the sliding bracket and the fixed disk. While meeting the support requirements of the rotating disk, the smoothness of the rotation of the rotating disk is guaranteed.

[0024] (6) By providing two chute grooves on the floating plate, in conjunction with two sets of guide sliders, the purpose of guiding the floating plate on the rotating plate and the floating plate on the driving plate can be effectively achieved, and a first guide path and a second guide path that intersect with each other can be effectively defined. The provision of the guide sliders not only facilitates the fixed connection with the driving plate or the rotating plate, but also allows for good assembly into the corresponding chute grooves, thereby achieving the purpose of guiding the sliding movement.

[0025] (7) By opening four long holes on the floating plate, after limiting the length arrangement direction and position of the long holes, mutually perpendicular slide grooves can be defined on the floating plate, thereby making the first guide path and the second guide path vertically distributed. In this way, with the help of the cooperative sliding of the floating plate on the first guide path and the second guide path, the eccentric transmission problem of the driving plate relative to the rotating plate can be well overcome, and the purpose of good synchronous rotation transmission can be achieved between the rotating bodies of two different axes.

[0026] (8) The guide slider is designed as a split form consisting of a base and a slider body. The base and the slider body can be snapped together and assembled from both sides of the plate body of the floating disk. 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 conveniently realize the assembly setting of the guide slider in the long hole.

[0027] (9) By providing an elastic abutment on the side of the slider body and utilizing the abutment between the elastic abutment and the inner wall of the side of the elongated hole, the occurrence of transmission gap is better avoided, and the relative movement between the floating plate and the driving plate, and between the rotating plate and the floating plate can be more effectively avoided, which is conducive to further improving the driving stability and quiet effect of the seat rotation assembly. A threaded insert is provided in the slider body, and the threaded hole provided on the threaded insert can be used to conveniently connect the guide slider to the driving plate through the slider fastening screw, or to connect the guide slider to the rotating plate through the connecting bolt, thereby improving the fixing stability of the guide slider.

[0028] Another object of the present application is to provide a vehicle equipped with the seat rotation assembly described in the present application. The vehicle of the present application has the technical advantages possessed by the seat rotation assembly described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to make the technical solution and advantages of this application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0052] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0053] In addition, in the description of this application, it should be stated that if terms indicating directions or positional relationships such as "up, down, left, right, front, back, inside, outside" appear, they are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing this application and for clarity and conciseness of the expression, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed or operate in a specific direction, and therefore cannot be understood as a limitation on this application. Taking the vehicle described in this application as an example, the direction words such as "up, down, left, right, front, and back" used in the embodiments are defined based on the up and down directions (also called height directions), left and right directions (also called width directions), and front and back directions (also called length directions) of the vehicle. "Inside and outside" are defined based on the outline of the corresponding component. For example, "inside" and "outside" are defined based on the outline of the vehicle, with the side of the vehicle outline close to the middle of the vehicle being "inside", and the opposite side being "outside".

[0054] In addition, in the description of this application, unless otherwise clearly defined, the terms "installed", "connected", "connection", and "connector" should be understood in a broad sense. For example, the 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, an indirect connection through an intermediate medium, or a connection between the two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood in combination with specific circumstances. The limiting terms such as "first, second, A, B, C, D" that appear in the description of this application are only for distinguishing similar features of different positions, affiliations or uses, so as to achieve the purpose of avoiding ambiguity and confusion, and cannot be understood as indicating or implying relative importance.

[0055] In this application, the terms "one embodiment," "some embodiments," "examples," "specific examples," or "some examples" mean that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0056] It should be emphasized that in the technologies related to the electric rotating disk of vehicle seats, the electric rotating disk is mostly fixedly installed on the vehicle body frame or the slide rail for the seat to move forward and backward, and then the seat is fixed to the turntable of the electric rotating disk. The electric rotating disk drives the seat to complete the rotation of the set angle. The electric rotating disk has a complex turntable structure, heavy weight, and high cost. The driving structure mostly adopts a structure in which a motor drives a gear to drive a tooth plate or a rack. This type of structure has a certain tooth matching gap, so the rotation transmission matching gap is large, resulting in jamming, looseness, etc. during the rotation and steering of the seat. An additional set of gap elimination mechanisms needs to be added, resulting in a high manufacturing cost and increased weight of the electric rotating disk. At the same time, the assembly of the entire mechanism is also relatively complicated.

[0057] Furthermore, because the seat is equipped with a backrest angle adjustment mechanism, a heating device, and a detection device for detecting whether the seat is occupied, a certain number of electrical lines are drawn from the seat. The wiring harness composed of these lines needs to pass through the electric rotary plate to connect to the vehicle control system. The existing electric rotary plate and its gap elimination mechanism are already complex in structure and assembly, and the need for rotational drive makes wiring harness layout very difficult. Arranging the wiring harness in a small and compact space also affects the assembly of the rotary plate. Therefore, it is often necessary to reserve a longer wiring harness and use circuitous wiring to avoid related structures. This not only increases the cost of the wiring harness, but also makes it easy for the wiring harness to become entangled with adjacent mechanisms and be pulled apart.

[0058] In view of the above problems existing in the relevant technologies, the present application innovatively proposes a new seat rotation assembly, providing a seat rotation drive solution that is conducive to improving the transmission fitting clearance problem.

[0059] The present application is described in detail below by way of exemplary embodiments. However, it should be understood that elements, structures, and features in one embodiment may also be beneficially combined in other embodiments without further description.

[0060] The embodiment of the first aspect of the present application provides a seat rotation assembly, which can be applied to scenarios where seats in a vehicle need to be rotated to meet the different facing directions of passengers, and can also be applied to various other types of seats with rotation requirements; an exemplary structure thereof is as follows Figure 1 、 Figure 2 and Figure 3 shown.

[0061] Generally speaking, the seat rotation assembly comprises a fixed plate 1, a rotating plate 5 rotatably mounted on the fixed plate 1, a drive device 2 mounted on the fixed plate 1, and a drive plate 3 and a floating plate 4 drivingly connected between the drive device 2 and the rotating plate 5. The drive plate 3 is located in the middle of the fixed plate 1 and is rotatable under the drive device 2. The floating plate 4 slides along a first guide path on the drive plate 3 and along a second guide path on the rotating plate 5. Both the first and second guide paths are arranged radially and intersect with each other, enabling the floating plate 4 to rotate synchronously with the drive plate 3, and the rotating plate 5 to rotate synchronously with the floating plate 4.

[0062] It should be pointed out that the fixed plate 1, driving plate 3, floating plate 4, rotating plate 5 and the pressure plate 6 described below in the car seat turntable are preferably arranged coaxially, and are sequentially stacked and fastened together from bottom to top. Therefore, the rotating plate 5 and the fixed plate 1 are coaxial, and the rotating plate 5 rotates with the axis of the fixed plate 1 and the rotating plate 5 as the rotation axis; however, although the driving plate 3 is arranged in the middle of the fixed plate 1, the driving device 2 mostly uses an adjuster 21 in the form of a gear transmission such as a planetary gear to achieve a reduction transmission drive for the rotation of the driving plate 3. Due to the presence of meshing transmission forms such as gears and ring gears, the rotation axis of the driving plate 3 may not be fixed and may be offset relative to the axis of the fixed plate 1, causing the rotation of the driving plate 3 to be eccentric relative to the rotating plate 5. Even if the transmission process of the adjuster 21 does not cause the axis of the driving plate 3 to be offset, the existence of assembly errors may also cause eccentricity between the driving plate 3 and the rotating plate 5. Therefore, a direct fixed connection cannot be used between the driving plate 3 and the rotating plate 5.

[0063] It is precisely for the above reasons that the car seat turntable of the present application adopts a transmission form of a driving plate 3, a floating plate 4 and a rotating plate 5. With the help of a guide sliding structure located on the radial direction of the floating plate 4, under the drive of the driving device 2, the driving plate 3 can drive the floating plate 4 to rotate synchronously through the guide sliding structure between the driving plate 3 and the floating plate 4, and the floating plate 4 can drive the rotating plate 5 to rotate synchronously through the guide sliding structure between the floating plate 4 and the rotating plate 5, thereby effectively improving the problems of jamming and looseness caused by the tooth matching gap in the gear transmission form; moreover, since the first guide path and the second guide path are arranged crosswise, located on two radial directions with a certain angle on the floating plate 4, with the help of the sliding action of the floating plate 4 on the driving plate 3 and the rotating plate 5, the problem of eccentric rotation transmission in which the rotation axes of the driving plate 3 and the rotating plate 5 do not coincide can be solved, thereby ensuring the smooth progress of the transmission, thereby providing a seat rotation drive solution that is conducive to improving the transmission matching gap problem.

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

[0065] Specifically, if Figure 3 and Figure 4 As shown, in some of the more preferred exemplary embodiments, the seat rotation assembly further includes a pressure plate 6 for press-fitting 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 and the ball bearing assemblies engage in rolling engagement. Configuring the assembly with the pressure plate 6 allows the rotating disk 5 to be securely press-fitted onto the fixed disk 1. Furthermore, a set of ball bearing assemblies is provided on the upper and lower sides of the rotating disk 5, respectively, ensuring a rolling engagement 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 friction during the rotation of the rotating disk 5, thereby enabling the rotating disk 5 to rotate smoothly on the fixed disk 1.

[0066] In a specific implementation, the fixed disk 1, the rotating disk 5, and the pressure plate 6 can all be configured as circular disks. A threading hole 102 can be provided in the middle of the fixed disk 1, a through hole 500 can be provided in the middle of the rotating disk 5, and a relief hole 600 can be formed in the middle of the annular pressure plate 6. The wiring harness 9 connecting the seat and the vehicle control system can be routed through the threading hole 102, the through hole 500, and the relief hole 600 in sequence. To facilitate the installation of the seat on the rotating disk 5, an upwardly protruding mounting platform 506 can be formed in the middle of the rotating disk 5. The mounting platform 506 has a mounting hole 507 provided on it. The mounting hole 507 is used to pass through the seat fixing bolt 52. The seat fixing bolt 52 can be passed through the mounting hole 507 from the bottom of the rotating disk 5 and screwed onto the seat, thereby achieving a fixed connection between the rotating disk 5 and the seat. Furthermore, the pressure plate 6 can be designed into a circular ring shape, so that the pressure plate 6 is press-fitted onto the edge of the rotating disk 5 located on the periphery of the mounting platform 506; a plurality of press-fit holes 601 are spaced apart at the edge of the pressure plate 6. After the pressure plate fastening bolts 61 provided in the press-fit holes 601 penetrate the fixed disk 1 and are screwed to the nuts 11 at the bottom of the fixed disk 1, the pressure plate 6 can be securely mounted on the fixed disk 1. The specific structural form of the ball assembly can be designed with reference to existing ball bearing structures. The ball assembly of this embodiment includes an annular retainer 801 and a plurality of steel balls 800 evenly spaced on the retainer 801. In order to realize the assembly of the ball assembly well, a first lower slide 101 can be formed on the upper surface of the fixed plate 1, and a first upper slide 501 can be formed on the lower surface of the rotating plate 5, and then the first ball assembly 8a in the ball assembly can be assembled into the ball slide defined by the first lower slide 101 and the first upper slide 501; similarly, a second lower slide 502 can be formed on the upper surface of the rotating plate 5, and a second upper slide 602 can be formed on the lower surface of the pressure plate 6, and then the second ball assembly 8b in the ball assembly can be assembled into the ball slide defined by the second lower slide 502 and the second upper slide 602.

[0067] As mentioned above, the driving device 2 has a variety of driving structure options. In this embodiment, Figure 5 As shown, in some preferred exemplary embodiments, the drive device 2 includes a motor 20 fixedly connected to the fixed plate 1 and a recliner 21 drivingly connected to the motor 20. The motor 20 is drivingly connected to the recliner 21 via a recliner connecting rod 200. The drive plate 3 is mounted on the recliner 21 and rotates under the drive of the recliner 21. The combination of the motor 20 and the recliner 21 in the drive device 2 not only facilitates drive control, but also enables the recliner 21 to achieve a deceleration and torque-increasing effect, thereby smoothly driving the drive plate 3 to rotate.

[0068] Of course, a center hole 100 can be provided at the center of the fixed plate 1, and a recliner connecting rod 200 provided on the power supply motor 20 can be inserted from the bottom of the fixed plate 1 into the interior of the car seat turntable to connect with the recliner 21. Furthermore, a motor positioning hole 103 can be provided on the fixed plate 1 to cooperate with a positioning pin and other structures provided on the motor 20 to enable rapid positioning and installation of the motor 20 on the fixed plate 1.

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

[0070] Of course, the above-mentioned sliding bracket 53 can also be in the form of a bracket or a solid structure, and the material can also be flexibly selected. In this embodiment, the sliding bracket 53 preferably adopts a rubber block with a solid structure, and a certain number of weight-reducing cavity structures are formed on the sliding bracket 53. Figure 6 As shown, in this embodiment, the top of the sliding bracket 53 is provided with a screw hole 530. This screw hole 530 can be set on an insert embedded in the sliding bracket 53 to improve the connection strength. The bracket mounting screw 54 provided on the rotating disk 5 is screwed into the screw hole 530 to achieve the fixed installation of the sliding bracket 53 on the rotating disk 5. At the same time, a plurality of positioning posts 531 can be provided on the top of the sliding bracket 53, and corresponding positioning holes are provided on the rotating disk 5. When the sliding bracket 53 is installed on the rotating disk 5, the positioning posts 531 are inserted into the corresponding positioning holes. The positioning posts 531 cooperate with the bracket mounting screw 54 to ensure the secure position 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, its elasticity can be directly achieved by using a material with elastic deformation properties; 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 downwardly arched plate, and the elastic support capacity of the elastic support part 532 is obtained or improved by utilizing the arch structure of the elastic support part 532 itself.

[0072] Based on the above-mentioned setting of the sliding bracket 53, Figure 4 As shown, in some preferred exemplary embodiments, the sliding brackets 53 are multiple and evenly spaced along the circumference of the rotating disk 5. Furthermore, preferably, multiple first grooves 533 are spaced apart on the surface where the elastic support portion 532 abuts the fixed disk 1, and each first groove 533 is arranged along the circumference of the rotating disk 5. The multiple sliding brackets 53 are evenly spaced apart at the bottom of the rotating disk 5 to provide multi-point support for the rotating disk 5, facilitating a more balanced and reliable support structure beneath the rotating disk 5. The multiple first grooves 533 formed at the bottom of the elastic support portion 532 of the sliding bracket 53 reduce the contact area between the elastic support portion 532 and the fixed disk 1. Furthermore, each first groove 533 is oriented along the circumference of the rotating disk 5. During rotation of the rotating disk 5 relative to the fixed disk 1, the ribs between adjacent first grooves 533 can slide smoothly along the circumference of the rotating disk 5, further reducing friction between the sliding bracket 53 and the fixed disk 1. This ensures smooth rotation of the rotating disk 5 while meeting the support requirements of the rotating disk 5.

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

[0074] The floating plate 4 is also provided with a first chute 401 and a second chute 402, each of which is provided with a guide slider 7. Specifically, the guide slider 7 includes a first slider 7a, which is fixedly connected to the drive plate 3 and slides in the first chute 401, and a second slider 7b, which is fixedly connected to the rotating plate 5 and slides in the second chute 402. The first slider 7a and the first chute 401 define a first guide path, while the second slider 7b and the second chute 402 define a second guide path. By providing two chute grooves on the floating plate 4 and cooperating with two sets of guide sliders 7, the floating plate 4 can effectively guide the sliding movement of the floating plate 4 on the rotating plate 5 and the driving plate 3, effectively defining intersecting first and second guide paths. The provision of the guide slider 7 not only facilitates secure connection to the drive plate 3 or the rotating plate 5, but also allows for smooth assembly into the corresponding chute, thereby achieving the purpose of guiding the sliding movement.

[0075] Continue as Figure 5 and Figure 7 As shown, in some preferred exemplary embodiments, the first chute 401 and the second chute 402 are each formed by two elongated holes that are centrosymmetrical about the center of the floating plate 4. Therefore, four elongated holes are required on the floating plate 4. Preferably, the four elongated holes can be respectively provided at the four corners of the floating plate 4. The corners of the floating plate 4 can be designed to protrude radially outward from the floating plate 4 to increase the space for the elongated holes. Accordingly, the first slider 7a and the second slider 7b are each provided in two corresponding elongated holes. The four elongated holes are all provided radially along the floating plate 4 and are evenly spaced around the circumference of the floating plate 4. By opening four long holes on the floating plate 4, and after defining the length arrangement direction and position of each long hole according to the above requirements, two mutually perpendicular slide grooves can be defined on the floating plate 4, so that the first guide path and the second guide path are vertically distributed. In this way, with the help of the coordinated sliding of the floating plate 4 on the first guide path and the second guide path, the eccentric transmission problem of the driving plate 3 relative to the rotating plate 5 can be well overcome, and the purpose of good synchronous rotation transmission can be achieved between the rotating bodies of two different axes.

[0076] Regarding the specific arrangement of the guide slider 7, there are of course a variety of different structural solutions to choose from; for example, a single structure or a split structure can be used. Figure 7As shown, since both the first and second chute grooves 401 and 402 are formed as elongated holes extending through the plate body of the floating plate 4, the guide slider 7 preferably has a split structure. Specifically, the guide slider 7 of this embodiment includes a base 70 and a slider body 71 assembled on the base 70. A top plate 710 is provided on top of the slider body 71. When the guide slider 7 is assembled in the elongated hole, the base 70 and top plate 710 are positioned on either side of the plate body of the floating plate 4 to confine the slider body 71 in the elongated hole. In view of the fact that the first slide groove 401 and the second slide groove 402 are both constructed in the form of long strip holes, the guide slider 7 is designed as a split form consisting of a base 70 and a slider body 71. The base 70 and the slider body 71 can be snapped together and assembled from both sides of the plate body of the floating plate 4. The bottom plate 700 of the base 70 which is larger than the width of the long strip hole and the top plate 710 on the top of the slider body 71 are used to define the guide slider 7 in the long strip hole, which can conveniently realize the assembly setting of the guide slider 7 in the long strip hole.

[0077] During the specific design, a side panel 701 can be designed on each side of the base panel 700, a snap-in window 702 can be opened on the side panel 701, and a snap-in head 712 can be correspondingly provided on the slider body 71; the slider body 71 is inserted between the two side panels 701, and the snap-in head 712 is snapped into the snap-in window 702 on the corresponding side, thereby realizing a quick snap-in assembly between the slider body 71 and the base 70.

[0078] At the same time, in order to secure the guide slider 7 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 securing the guide slider 7 to the drive disk 3 or the rotating disk 5 can be formed in the threaded insert 72. The threaded insert 72 is provided in the slider body 71, and the threaded hole 720 provided in the threaded insert 72 can be used to conveniently secure the guide slider 7 to the drive disk 3 via the slider fastening screw 31, or to secure the guide slider 7 to the rotating disk 5 via the connecting bolt 51, thereby improving the secure installation of the guide slider 7.

[0079] Moreover, while the threaded connection is realized by using the threaded hole 720, a positioning structure can be designed between the guide slider 7 and the rotating disk 5, or between the guide slider 7 and the driving disk 3. Taking the installation of the second slider 7b on the rotating disk 5 as an example, Figure 4 and Figure 5 、 Figure 7As shown, a through-hole 503 is provided on the rotating disk 5, and two positioning notches 504 are provided on the side of the through-hole 503 opposite to each other; a connecting bolt 51 is inserted into the through-hole 503 and screwed into the threaded hole 720 on the second slider 7b; two positioning protrusions 721 are also provided on the threaded insert 72, respectively located on both sides of the threaded hole 720. When the second slider 7b is set at a position corresponding to the through-hole 503 on the bottom of the rotating disk 5, the two positioning protrusions 721 are respectively inserted into the two positioning notches 504 at the through-hole 503, so as to realize rapid positioning of the second slider 7b on the rotating disk 5. Thereafter, the connecting bolt 51 is screwed into the threaded hole 720 to realize reliable fixation of the second slider 7b on the rotating disk 5. The cooperation between the positioning protrusion 721 and the positioning notch 504 can also prevent the second slider 7b from rotating on the rotating disk 5. The arrangement of the first slider 7a on the drive disk 3 can be similar to the arrangement of the second slider 7b on the rotating disk 5. In the case where the first slider 7a is arranged on top of the drive disk 3, a recessed groove 302 can be formed on the drive disk 3 at the location where the first slider 7a is to be arranged, making it easier to locate the first slider 7a in the correct position on the drive disk 3. The first slider 7a is then secured to the drive disk 3 using a slider fastening screw 31 that passes through the drive disk 3 from below. Furthermore, since the slider fastening screw 31 may protrude upward after passing through the first slider 7a and potentially interfere with the rotating disk 5 located above, a clearance hole 505 can be provided at a corresponding location 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 the floating plate 4, elastic abutment portions 713 are provided on both sides of the slider body 71 of this embodiment. The two elastic abutment portions 713 respectively abut against the inner walls of the elongated hole. By providing the elastic abutment portions 713 on the sides of the slider body 71, the elastic abutment portions 713 abut against the inner walls of the elongated hole, thereby better avoiding the occurrence of transmission clearance. 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 plate 4 and the driving plate 3, and between the rotating plate 5 and the floating plate 4, during the synchronous rotation of the floating plate 4 with the driving plate 3, and the rotating plate 5 with the floating plate 4, thereby further improving the driving stability 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 directly 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, so that the elastic abutment portion 713 is in the shape of a plate that arches outward. The elastic abutment portion 713's inherent arched structure can be utilized to achieve or enhance its elastic support and abutment properties.

[0082] At the same time, a plurality of second grooves 714 can be formed 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, a plurality of ribs are formed on the surface of the elastic abutment portion 713, which are formed between adjacent second grooves 714. The elastic abutment portion 713 abuts against the inner wall of the side of the elongated hole through these ribs, thereby achieving 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. Moreover, 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, further reducing the friction between the guide slider 7 and the elongated hole, making the guided sliding of the floating plate 4 on the driving plate 3 and the guided sliding of the floating plate 4 on the rotating plate 5 smoother.

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

[0084] Continue as shown Figures 1 to 5 As shown, the seat rotation assembly includes, from bottom to top, a fixed plate 1, a driving plate 3, and a rotating plate 5. The rotating plate 5 is rotatably mounted on the fixed plate 1 to accommodate the seat, and a through-hole 500 is provided in the center of the rotating plate 5. A wire threading hole 102 is provided on the fixed plate 1, and a driving device 2 is provided on the fixed plate 1 for driving the driving plate 3 to rotate. The driving plate 3 is rotatably connected to the rotating plate 5 to drive the rotating plate 5 to rotate. Furthermore, a power input portion 3a for connecting to the driving device 2 is provided in the center of the driving plate 3. Furthermore, the plate body of the driving plate 3 is provided with wiring holes 300 that are semi-enclosed and distributed around the periphery of the power input portion 3a. The wiring harness 9 from the seat passes through the through-hole 500, the wiring hole 300, and the wire threading hole 102 in sequence to connect to the outside.

[0085] Based on the above-mentioned overall design principles, the seat's wiring harness 9 is routed through a wire hole 102, a wiring hole 300, and a through-hole 500, respectively, provided on the fixed plate 1, the driving plate 3, and the rotating plate 5. This allows for smooth routing of the wiring harness 9 to the vehicle floor beneath the seat, where it can then connect to the vehicle's control system to meet seat back angle adjustment, seat heating, and related testing requirements. Given that the power input portion 3a in the center of the driving plate 3 requires connection to the drive device 2 and that the driving plate 3 rotates 180° to achieve forward and backward steering of the seat via the rotating plate 5, the wiring hole 300 on the driving plate 3 is designed to be semi-enclosed. This allows for routing of the wiring harness 9 without interfering with the rotation of the driving plate 3. During the rotation of the driving plate 3, the wiring harness 9 can be positioned at different locations within the wiring hole 300, which consistently avoids the wiring harness 9, preventing problems such as difficult routing of the wiring harness 9 and entanglement with adjacent mechanisms. This improves the layout of the seat's wiring harness 9 within the seat rotating assembly.

[0086] Specifically, if Figure 5 As shown, in some of the more preferred exemplary embodiments, a center hole 100 is opened in the center of the fixed plate 1, and the driving device 2 includes a motor 20 fixed to the bottom of the fixed plate 1 and a recliner 21 provided above the center hole 100. The recliner connecting rod 200 provided on the motor 20 passes through the center hole 100 and is connected to the recliner 21. The driving plate 3 is provided on the recliner 21 and rotates under the drive of the recliner 21. The driving device 2 adopts a matching form of the motor 20 and the recliner 21, which not only facilitates drive control, but also allows the recliner 21 to achieve the effect of deceleration and torque increase, thereby smoothly driving the driving plate 3 to rotate. By opening the center hole 100 at the center position of the fixed plate 1, it is convenient to install the recliner connecting rod 200, and the recliner 21 can be easily arranged inside the seat rotation assembly so as to be assembled and connected with the driving plate 3.

[0087] Given that the edge of the wiring hole 300 may scrape against the wiring harness 9 during the rotation of the drive disk 3, a flange structure may be preferably designed on the plate body of the drive disk 3; specifically, a flange 301 is formed at the edge of the wiring hole 300. Since the wiring harness 9 passes through the wiring hole 300, there is a possibility that the wiring harness 9 and the edge of the wiring hole 300 may come into contact during the rotation of the drive disk 3. The flange 301 at the edge of the wiring hole 300 can prevent the edges of the wiring hole 300 from being scratched by sharp corners and burrs, thereby preventing the wiring harness 9 from being damaged by these sharp corners and burrs.

[0088] Based on the above arrangement of the first slider 7a on the driving disk 3, preferably, as Figure 5As shown, in some preferred exemplary embodiments, the drive plate 3 is provided with two transmission output portions 3b for respectively securing the two first sliders 7a. These two transmission output portions 3b are located at the edges of the drive plate 3 and are symmetrically distributed about the center of the drive plate 3. Furthermore, the transmission output portions 3b are arranged to protrude radially outward from the drive plate 3. Given that the drive plate 3 should not be oversized to minimize internal space occupied by the seat rotation assembly and conserve material, the two transmission output portions 3b for power output are positioned outwardly at the edges of the drive plate 3. This effectively increases the output torque of the drive plate 3, thereby aligning with the positions of the corresponding two first guide slots 401 on the floating plate 4, effectively meeting the requirements for the placement of the two first sliders 7a. Of course, the aforementioned recessed grooves 302 for mounting and positioning the first sliders 7a can be provided on the transmission output portion 3b.

[0089] As mentioned above, in some preferred exemplary embodiments, the floating plate 4 is rectangular in shape, with a wire hole 400 formed in the hollow center of the floating plate 4. The four corners of the floating plate 4 protrude radially outward, and the four elongated holes are disposed at the four corners of the floating plate 4. The rectangular structure of the floating plate 4 effectively reduces material consumption and effectively accommodates the arrangement of the four elongated holes. The outwardly protruding corners of the floating plate 4 ensure that the elongated holes have the required length within the relatively small overall size of the floating plate 4, and also facilitates the assembly of the first slider 7a on the drive plate 3 and the second slider 7b on the rotating plate 5.

[0090] And, combined with Figure 8 and Figure 9 As shown, in some of the more preferred exemplary embodiments, a sliding sleeve 41 is provided on the plate body of the floating plate 4. The sliding sleeve 41 is clamped at the edge of the wire hole 400 and forms an elastic support between the floating plate 4 and the rotating plate 5, and between the floating plate 4 and the driving plate 3. The number of sliding sleeves 41 provided can be flexibly selected. In this embodiment, a sliding sleeve 41 is provided at each of the four corners of the floating plate 4, corresponding to the inner edge of the wire hole 400. The addition of the sliding sleeve 41 to the floating plate 4 can form a reliable isolation support in the narrow space between the floating plate 4 and the rotating plate 5, and between the floating plate 4 and the driving plate 3, preventing direct scratching between the floating plate 4 and the rotating plate 5, or between the floating plate 4 and the driving plate 3. The sliding sleeve 41 uses an elastic support method to accommodate the upward and downward fluctuations in the position of the rotating plate 5 and the floating plate 4 caused by changes in the weight of the seat, and can also provide a certain buffering effect. There are of course many ways to implement 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 provided at the top and bottom of the sliding sleeve 41.

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

[0092] The driving plate 3 and the rotating plate 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 eccentric amount of the floating plate 4 set between the two, the driving plate 3 can smoothly drive the rotating plate 5 to rotate synchronously to carry the seat to complete a 180° turn.

[0093] In the sliding structure of floating plate 4, elongated holes at its four corners form a slideway, each fitted with a guide slider 7. The first slider 7a is fixedly connected to the drive plate 3, while the second slider 7b is fixedly connected to the rotating plate 5, allowing the floating plate 4 to slide along mutually perpendicular guide paths. Power is transmitted by floating plate 4, and its sliding absorbs rotational eccentricity, effectively achieving synchronized rotational transmission between the drive plate 3 and the rotating plate 5, overcoming eccentricity. Furthermore, the elastic abutment 713 designed on the side of the guide slider 7 effectively reduces backlash during transmission.

[0094] Moreover, with the help of the semi-enclosed wiring hole 300 designed on the driving disc 3, the wiring harness 9 can be conveniently laid through the entire seat rotation assembly, and the wiring hole 300 can avoid the wiring harness 9 during the rotation of the driving disc 3. Figure 8 and Figure 10 and Figure 11 As shown, when the driving plate 3 drives the floating plate 4 and the rotating plate 5, Figure 8 The original position shown is rotated to Figure 10 When the wiring harness 9 is in the 90° position shown in FIG. 3 , it is switched from one end of the wiring hole 300 to the middle of the wiring hole 300. When the driving disk 3 drives the floating disk 4 and the rotating disk 5 to rotate, the wiring harness 9 is switched from one end of the wiring hole 300 to the middle of the wiring hole 300. Figure 10 The 90° position shown is rotated to Figure 11 In 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. During this entire process, the wiring harness 9 does not need to move. Instead, the semicircular escape path provided by the wiring hole 300 allows the wiring harness 9 to be perfectly avoided during the movement of the seat rotation assembly. Therefore, the seat rotation assembly of the present application avoids the problem of the wiring harness 9 being tangled. Simultaneously, the layout is simple, compatible with the layout requirements of various types of seat wiring harnesses 9. The wiring harness 9 does not need to be extended or circumvented, thus reducing the configuration cost of the wiring harness 9.

[0095] To sum up, the seat rotation assembly of this embodiment adopts a transmission form of a drive plate 3, a floating plate 4 and a rotating plate 5. With the help of a guide sliding structure located on the radial direction of the floating plate 4, under the drive of the drive device 2, the drive plate 3 can drive the floating plate 4 to rotate synchronously through the guide sliding structure between the drive plate 3 and the floating plate 4, and the floating plate 4 can drive the rotating plate 5 to rotate synchronously through the guide sliding structure between the floating plate 4 and the rotating plate 5, thereby effectively improving the problems of jamming and looseness caused by the tooth matching gap in the gear transmission form; moreover, since the first guide path and the second guide path are arranged crosswise, located on two radial directions with a certain angle on the floating plate 4, with the help of the sliding action of the floating plate 4 on the drive plate 3 and the rotating plate 5, the problem of eccentric rotation transmission in which the rotation axes of the drive plate 3 and the rotating plate 5 do not coincide can be solved, thereby ensuring the smooth transmission, thereby providing a seat rotation drive solution that is conducive to improving the transmission matching gap problem.

[0096] Furthermore, the seat rotation assembly of this embodiment has a wire threading hole 102, a wiring hole 300, and a through-hole 500 respectively formed on the fixed plate 1, the driving plate 3, and the rotating plate 5, for the threading and arrangement of the seat wiring harness 9. The wiring harness 9 can be smoothly guided to the vehicle body floor below the seat and then connected to the vehicle control system to meet the needs of seat back angle adjustment, seat heating, and related detection. Since the power input portion 3a in the middle of the driving plate 3 needs to be connected to the drive device 2 and the driving plate 3 needs to rotate 180° to meet the need of driving the seat to achieve forward and backward steering through the rotating plate 5, the wiring hole 300 on the driving plate 3 is designed to be semi-enclosed. While allowing the wiring harness 9 to pass through, the wiring harness 9 will not interfere with the rotation of the driving plate 3. During the rotation of the driving plate 3, the wiring harness 9 can be located at different positions of the wiring hole 300. The wiring hole 300 can always avoid the wiring harness 9, avoiding problems such as difficult wiring of the wiring harness 9 and easy entanglement of the wiring harness 9 with adjacent mechanisms, thereby improving the layout conditions of the seat wiring harness 9 in the seat rotation assembly. Furthermore, the drive device 2 utilizes a motor 20 and a recliner 21, which not only facilitates drive control but also allows the recliner 21 to achieve a deceleration and torque-increasing effect, thereby smoothly driving the drive plate 3 in rotation. A central hole 100 is provided at the center of the fixed plate 1, facilitating the installation of the motor 20 and recliner connecting rod 200. The recliner 21 can also be conveniently positioned within the seat rotating assembly for assembly and connection with the drive plate 3.

[0097] An embodiment of the second aspect of the present application provides a vehicle, which is equipped with the seat rotation assembly provided by the first embodiment; therefore, the vehicle has the technical advantages possessed by the above-mentioned seat rotation assembly.

[0098] By configuring the seat rotation assembly of the present application on the vehicle, the bidirectional sliding structure of the floating plate 4 is adopted to solve the eccentric transmission problem in the seat rotation assembly, so that the seat rotation assembly can achieve synchronous rotation output; the waist-shaped hole designed on the drive plate 3, that is, the semi-enclosed wiring hole 300 can allow the seat wiring harness 9 to pass from top to bottom and connect with the vehicle control system. When the seat rotates, the wiring hole 300 rotates around the wiring harness 9, avoiding the problem of tangled wires. The structure is simple to assemble, with few parts and low 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 with good compatibility and versatility.

[0099] The above description is merely a preferred embodiment of the present application. The detailed configuration explanations, specific structural configuration examples, and assembly connection descriptions are provided for the purpose of providing sufficient disclosure to facilitate the implementation of the present application by those skilled in the art, and are not intended to limit the scope of protection of the present application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
