Description

Technical Field

[0001] This disclosure relates to the field of vehicle component technology, specifically to a turntable device, a seat, and a vehicle. Background Technology

[0002] Seats are an important part of a vehicle, and different types of vehicles have different requirements for seats. In addition to common functions such as backrest adjustment, forward and backward movement, and vertical height adjustment, seat rotation function is also required to meet the needs of passengers entering the vehicle.

[0003] In related technologies, the rotation of vehicle seats is often achieved through a turntable structure. However, when assembling wiring harnesses, the turntable structure is prone to cutting the wiring harnesses due to the sharp edges of the components, reducing safety performance and affecting the normal use of the seats. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this disclosure provides a turntable device, a seat, and a vehicle.

[0005] According to a first aspect of the present disclosure, a turntable device is provided, the turntable device including a fixed disk, a rotating disk and a protective sleeve, the fixed disk being used to connect with a first external component, and the rotating disk being used to connect with a second external component; The fixed disk includes a fixed disk body and a rotating sleeve. The rotating sleeve is protrudingly connected to the fixed disk body in a first direction. The rotating disk has a rotating hole and is rotatably fitted onto the rotating sleeve through the rotating hole. The rotating sleeve has a first through hole inside. The protective sleeve is connected to the rotating disk and covers at least the side of the rotating sleeve away from the fixed disk body. The protective sleeve also has a second through hole opposite to the first through hole.

[0006] When assembling the wire harness, the wire harness passes through the first through hole in the rotating sleeve, and the rotating sleeve is formed as an end edge on the side away from the fixed disk body in the first direction. By providing a protective sleeve, and the protective sleeve at least covering the end edge of the rotating sleeve, the end edge can be effectively prevented from cutting the wire harness, thereby improving safety performance and extending the service life of the wire harness.

[0007] In some embodiments, the rotating disk is formed with a mounting groove arranged around the rotating hole, the protective sleeve is at least partially disposed within the mounting groove, and the protective sleeve is connected to the groove wall of the mounting groove.

[0008] The mounting groove provides positioning for the installation of the protective sleeve, and the sleeve also effectively utilizes the space within the groove, improving the compactness of the structural design. In addition to protecting the wiring harness, the protective sleeve also provides a degree of sealing between the rotating and fixed disks, preventing external water, dust, and other impurities from entering the internal spaces of both disks.

[0009] In some embodiments, the protective sleeve includes an annular sleeve, the annular sleeve including an annular sleeve body, a first annular flange and a second annular flange, the first annular flange and the second annular flange being respectively connected to both sides of the annular sleeve body; The first annular flange is disposed opposite to at least a portion of the inner wall of the rotating sleeve, the second annular flange is disposed opposite to at least a portion of the outer wall of the rotating sleeve, and the second annular flange is connected to the groove wall of the mounting groove.

[0010] The annular sleeve body is positioned opposite to the end edge of the rotating sleeve, effectively protecting the end edge. The first annular flange protects the inner wall of the rotating sleeve, and the second annular flange protects the outer wall of the rotating sleeve. When the wire harness needs to pass through the first through hole of the rotating sleeve, the wire harness can pass through the second through hole of the protective sleeve. This smooth protective sleeve effectively protects the wire harness, preventing the end edge of the rotating sleeve from wearing or cutting the wire harness, extending its service life, and improving safety.

[0011] In some embodiments, one of the second annular flange and the groove wall of the mounting groove is provided with at least one locking block, and the other is provided with at least one locking slot, wherein the locking block and the locking slot are correspondingly engaged.

[0012] The locking blocks and slots are designed to engage with each other, allowing the protective sleeve to be connected to the rotating disk. Multiple locking blocks can be configured, spaced apart around the second annular flange. Similarly, multiple slots can be configured, spaced apart around the mounting groove.

[0013] In some embodiments, the turntable device further includes a drive bracket, a drive unit, and a transmission unit; A receiving cavity is formed between the rotating disk and the fixed disk, the driving bracket is disposed on the outer wall of the fixed disk body, and the driving part is disposed on the driving bracket; The transmission unit is disposed in the receiving cavity and connected to the rotating disk, and the driving unit is connected to the transmission unit to drive the rotating disk to rotate.

[0014] The drive unit is located on the outer wall of the fixed plate, avoiding occupying the limited internal space; the transmission unit is arranged inside the housing cavity, making the entire device more compact and efficient. The housing cavity provides a relatively good sealing environment for the internal structure, reducing the ingress of dust, moisture, or other foreign objects. In addition, if the drive unit or transmission unit malfunctions, it can be disassembled and repaired or replaced separately. The drive bracket, as an independent component, can be installed and adjusted without affecting other parts.

[0015] In some embodiments, the turntable device further includes an elastic element that connects the drive bracket and the fixed disc body.

[0016] By incorporating this elastic element, the vibration and abnormal noise caused by the instantaneous action of the drive motor on the drive bracket can be effectively reduced. For example, the elastic element can be a spring, with one end connected to the fixed plate body and the other end connected to the drive bracket.

[0017] In some embodiments, the driving unit includes a drive motor and a drive gear, and the transmission unit includes a drive rack; The drive motor is mounted on the drive bracket, the drive gear is connected to the drive motor in a transmission manner, and the drive gear is located within the receiving cavity; The drive rack is arranged around the rotating hole on the rotating disk and is connected to the drive gear for transmission.

[0018] When the drive motor is working, it can drive the drive gear to rotate. The drive gear is connected to the drive rack. Since the drive rack is set on the rotating disk and arranged around the rotating hole, that is, the drive rack is constructed as an arc-shaped rack, the rotating disk can be driven to rotate when the drive gear rotates.

[0019] In some embodiments, the turntable device further includes a positioning bracket, and the fixed plate body has an installation opening; The drive gear extends into the receiving cavity through the mounting opening, and the positioning bracket passes through the mounting opening and is connected to the drive bracket; The positioning bracket has a positioning hole, and the gear shaft of the drive gear is rotatably disposed in the positioning hole.

[0020] Specifically, by creating an installation opening on the fixed plate body, the transmission connection between the drive gear and the drive rack is facilitated. Secondly, by setting a positioning bracket, the installation of the drive gear is convenient and stable. Furthermore, by connecting the positioning bracket to the drive bracket, drilling holes in the fixed plate is avoided for installation.

[0021] In some embodiments, the turntable device further includes at least one clamp and at least one limiting member; The clamp is connected to the fixed disk body and at least partially covers the rotating disk in the first direction to restrict the rotating disk from detaching from the fixed disk in the first direction; Wherein, a gap is formed between the clamp and the rotating disk in the first direction, and the limiting member is disposed on the clamp and at least partially located within the gap to form sliding friction with the rotating disk.

[0022] The fixed disk is used to connect with the first external component, and the rotating disk is rotatably disposed on the fixed disk and used to connect with the second external component. The clamps disposed on the fixed disk can prevent the rotating disk from detaching from the fixed disk.

[0023] In addition, a gap is formed between the clamp and the rotating disk. A limiting member is disposed on the clamp and is at least partially located within this gap, and the limiting member can generate sliding friction with the rotating disk. That is, through this limiting member, the gap between the clamp and the rotating disk can be effectively filled, reducing the possibility of the rotating disk moving due to this gap, and improving the stability and accuracy of the rotating disk.

[0024] In some embodiments, the limiting member includes a limiting base and at least one elastic protrusion; The elastic protrusion is connected to the limiting base, the limiting base is connected to the clamp, the elastic protrusion is disposed in the gap and protrudes towards the rotating disk to form sliding friction with the rotating disk, and the elastic protrusion can undergo elastic deformation in the first direction.

[0025] By setting the elastic protrusion that can undergo elastic deformation, even if the gap between the clamp and the rotating disk becomes smaller, the elastic protrusion can still deform to fill and support the gap between the clamp and the rotating disk, reduce the possibility of the rotating disk moving due to the gap, and improve the stability and accuracy of the rotating disk.

[0026] In some embodiments, the elastic protrusions are provided in multiples, and the multiple elastic protrusions are arranged at intervals around the rotating hole on the limiting base.

[0027] By setting multiple elastic protrusions, the stability of the limiting component support can be effectively improved.

[0028] In some embodiments, one of the limiting base and the clamp is provided with at least one snap-fit ​​block, and the other is provided with at least one snap-fit ​​groove, wherein the snap-fit ​​block and the snap-fit ​​groove are engaged in a corresponding snap-fit ​​engagement.

[0029] By setting multiple elastic protrusions, the stability of the limiting component support can be effectively improved.

[0030] According to a second aspect of the present disclosure, a seat is also provided, the seat including a seat body, a seat slide rail and the aforementioned turntable device; wherein, the first external component is configured as the seat slide rail, and the fixed plate is slidably disposed on the seat slide rail; the second external component is configured as the seat body.

[0031] According to a third aspect of the present disclosure, a vehicle is also provided, the vehicle including the aforementioned seat.

[0032] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: when assembling a wire harness, the wire harness passes through a first through hole in a rotating sleeve, and the rotating sleeve is formed as an end edge on the side away from the fixed disk body in a first direction; by providing a protective sleeve, and the protective sleeve at least covering the end edge of the rotating sleeve, the end edge can be effectively prevented from causing damage to the wire harness, thereby improving safety performance and extending the service life of the wire harness.

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0047] In this disclosure, unless otherwise stated, the directional terms "first direction" and "second direction" refer to two intersecting directions. For example, the first direction and the second direction can be perpendicular to each other, as detailed in the following reference. Figure 1 As shown. The directional terms used, such as "inner" and "outer", refer to the inner and outer parts of the specific structural outline; the terms used, such as "first" and "second", are only used to distinguish one element from another and do not have any sequential or important meaning.

[0048] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0049] Reference Figures 1 to 10 As shown, this disclosure provides a turntable device, which includes a fixed disk 11, a rotating disk 12, and a protective sleeve 13. The fixed disk 11 is used to connect with a first external component, and the rotating disk 12 is used to connect with a second external component.

[0050] The fixed disk 11 includes a fixed disk body 111 and a rotating sleeve 112. The rotating sleeve 112 is protrudingly connected to the fixed disk body 111 in a first direction A. The rotating disk 12 has a rotating hole 120, and the rotating disk 12 is rotatably fitted onto the rotating sleeve 112 through the rotating hole 120.

[0051] The rotating sleeve 112 has a first through hole 1120 inside. The protective sleeve 13 is connected to the rotating disk 12 and covers at least the side of the rotating sleeve 112 away from the fixed disk body 111. The protective sleeve 13 has a second through hole 130 opposite to the first through hole 1120.

[0052] In the above technical solution, when assembling the wire harness, the wire harness passes through the first through hole 1120 in the rotating sleeve 112, and the rotating sleeve 112 is formed as an end edge on the side away from the fixed disk body 111 in the first direction A; by providing a protective sleeve 13, and the protective sleeve 13 at least covers the end edge of the rotating sleeve 112, the end edge can be effectively prevented from causing cuts to the wire harness, thereby improving safety performance and extending the service life of the wire harness.

[0053] Optionally, refer to Figure 1 and Figure 5 As shown, the rotating disk 12 has a mounting groove 121, which is arranged around the rotating hole 120. The protective sleeve 13 is at least partially disposed in the mounting groove 121, and the protective sleeve 13 is connected to the groove wall of the mounting groove 121.

[0054] In this embodiment, the mounting groove 121 provides positioning for the installation of the protective sleeve 13, and the protective sleeve 13 also effectively utilizes the space of the mounting groove 121, improving the compactness of the structural design. In addition, besides protecting the wire harness as described above, the protective sleeve 13 also provides a certain degree of sealing between the rotating disk 12 and the fixed disk 11, preventing external water, dust, and other impurities from entering the internal space of the rotating disk 12 and the fixed disk 11.

[0055] Furthermore, the protective sleeve 13 can be connected to the groove wall of the mounting groove 121 in any suitable manner, and this disclosure does not limit this. For example, refer to Figure 5 and Figure 7 As shown, one of the second annular flange 133 of the protective sleeve 13 and the groove wall of the mounting groove 121 can be provided with at least one locking block 100, and the other can be provided with at least one locking slot 200. The locking block 100 and the locking slot 200 are correspondingly engaged to connect the protective sleeve 13 to the rotating disk 12. There can be multiple locking blocks 100, which can be arranged in pairs around the second annular flange 133. There can also be multiple locking slots 200, which can be arranged in pairs around the mounting groove 121.

[0056] Optionally, refer to Figure 4 and Figure 7 As shown, the protective sleeve 13 includes an annular sleeve, which includes an annular sleeve body 131, a first annular flange 132 and a second annular flange 133. The first annular flange 132 and the second annular flange 133 are respectively connected to the two sides of the annular sleeve body 131. The first annular flange 132 is disposed opposite to at least a portion of the inner wall of the rotating sleeve 112, the second annular flange 133 is disposed opposite to at least a portion of the outer wall of the rotating sleeve 112, and the second annular flange 133 is connected to the groove wall of the mounting groove 121.

[0057] First, the annular sleeve body 131 is positioned opposite to the end edge of the rotating sleeve 112, effectively protecting the end edge. The first annular flange 132 protects the inner wall of the rotating sleeve 112, and the second annular flange 133 protects the outer wall of the rotating sleeve 112. When the wire harness needs to pass through the first through hole 1120 of the rotating sleeve 112, the wire harness can pass through the second through hole 130 of the protective sleeve 13. The smooth protective sleeve 13 effectively protects the wire harness, preventing the end edge of the rotating sleeve 112 from wearing or cutting the wire harness, extending its service life, and improving safety.

[0058] Additionally, refer to Figure 1As shown, at least one mounting part 122 may be provided on the rotating disk 12, and the mounting part 122 is used to connect with the first external component.

[0059] In this embodiment, by providing a mounting portion 122 on the rotating disk 12, it is convenient to connect with the first external component, providing a basis for the connection. The mounting portion 122 can be constructed as any suitable mounting structure, and this disclosure does not limit it. For example, the mounting portion 122 can be a mounting nut, which can be fixed to the rotating disk 12, and multiple mounting nuts can be provided, with multiple mounting nuts arranged in pairs around the rotating hole 120.

[0060] In another embodiment, refer to Figure 2 and Figure 3 As shown, the turntable device also includes a drive bracket 14, a drive unit 15, and a transmission unit 16; a receiving cavity is formed between the rotating disk 12 and the fixed disk 11, the drive bracket 14 is disposed on the outer wall of the fixed disk body 11, and the drive unit 15 is disposed on the drive bracket 14; the transmission unit 16 is disposed in the receiving cavity and connected to the rotating disk 12, and the drive unit 15 and the transmission unit 16 are connected in a transmission connection to drive the rotating disk 12 to rotate.

[0061] In this embodiment, the drive unit 15 is located on the outer wall of the fixed plate 11, avoiding occupying the limited internal space; the moving part 16 is arranged inside the receiving cavity, making the entire device more compact and efficient. The receiving cavity can provide a relatively good sealing environment for the internal structure, reducing the ingress of dust, moisture or other foreign objects. In addition, if the drive unit 15 or the transmission unit 16 malfunctions, it can be disassembled and repaired or replaced separately. The drive bracket 14, as an independent component, can be installed and adjusted without affecting other components.

[0062] The drive bracket 14 can be constructed in any suitable shape and structure, and this disclosure does not limit it. Similarly, the drive unit 15 can be constructed in any suitable drive structure, and this disclosure does not limit it. Furthermore, the transmission unit 16 can be constructed in any suitable transmission structure, and this disclosure does not limit it.

[0063] In another embodiment, reference is made to... Figure 2 and Figure 3 As shown, the drive unit 15 includes a drive motor 151 and a drive gear 152, and the transmission unit 16 includes a drive rack 161; the drive motor 151 is disposed on the drive bracket 14, the drive gear 152 is connected to the drive motor 151 in a transmission manner, and the drive gear 152 is located in the receiving cavity; the drive rack 161 is arranged around the rotating hole 120 on the rotating disk 12 and is connected to the drive gear 152 in a transmission manner.

[0064] In this embodiment, when the drive motor 151 is operating, it drives the drive gear 152 to rotate. The drive gear 152 is connected to the drive rack 161. Since the drive rack 161 is located on the rotating disk 12 and arranged around the rotating hole 120, that is, the drive rack 161 is constructed as an arc-shaped rack, the rotation of the drive gear 152 drives the rotating disk 12 to rotate. The rotation direction of the rotating disk 12 can be adjusted by rotating the drive motor 151. For example, if the motor shaft of the drive motor 151 rotates clockwise, the rotating disk 12 can rotate clockwise; if the motor shaft of the drive motor 151 rotates counterclockwise, the rotating disk 12 can rotate counterclockwise, thus satisfying the need for different rotation directions.

[0065] Alternatively, refer to 2. Figure 3 as well as Figure 8 As shown, the turntable device also includes a positioning bracket 18, and the fixed plate body 111 has an installation opening 1110; the drive gear 152 extends into the receiving cavity through the installation opening 1110, and the positioning bracket 18 passes through the installation opening 1110 and is connected to the drive bracket 14; the positioning bracket 18 has a positioning hole 180, and the gear shaft of the drive gear 152 is rotatably disposed in the positioning hole 180.

[0066] In this embodiment, firstly, by opening an installation opening 1110 on the fixed disk body 111, the transmission connection between the drive gear 152 and the drive rack 161 is facilitated. Secondly, by providing a positioning bracket 18, the installation of the drive gear 152 is facilitated, ensuring the stability of the drive gear 152 installation. Furthermore, by connecting the positioning bracket 18 to the drive bracket 14, drilling holes in the fixed disk 11 for installation is avoided. The positioning bracket 18 can be fixed to the drive bracket 14 using fasteners; however, this disclosure does not limit the specific method of connecting the positioning bracket 18 to the drive bracket 14, nor does it limit the shape and specific structure of the positioning bracket 18.

[0067] Optionally, refer to Figure 2 As shown, the turntable device also includes an elastic element 17, which connects the drive bracket 14 and the fixed disk body 111. By providing this elastic element 17, the vibration and abnormal noise caused by the instantaneous action of the drive motor 151 on the drive bracket 14 can be effectively reduced. For example, the elastic element 17 can be a spring, with one end connected to the fixed disk body 111 and the other end connected to the drive bracket 14.

[0068] Optionally, refer to Figure 3 As shown, the turntable device may also include a shaft assembly 25, which is sleeved on the rotating sleeve 112 and located between the rotating hole 120 and the rotating sleeve 112.

[0069] By providing the shaft assembly 25, the gap between the rotating disk 12 and the rotating sleeve 112 can be reduced, and abnormal noise generated during the rotation of the rotating disk 12 relative to the fixed disk 11 can be eliminated. In addition, the shaft assembly 25 also provides good sealing performance. Regarding the specific structure of the shaft assembly 25, it can be constructed as a shaft sleeve made of PTEE (Polytetrafluoroethylene), but this disclosure does not limit the specific material and shape of the shaft assembly 25.

[0070] In other implementations, refer to Figure 1 and Figure 6 As shown, the turntable device also includes at least one clamp 19 and at least one limiting member 191; the clamp 19 is connected to the fixed plate body 111 and at least partially covers the rotating plate 12 in the first direction A to restrict the rotating plate 12 from detaching from the fixed plate 11 in the first direction A; wherein, a gap 190 is formed between the clamp 19 and the rotating plate 12 in the first direction A, and the limiting member 191 is disposed on the clamp 19 and at least partially located within the gap 190 to form sliding friction with the rotating plate 12.

[0071] In this embodiment, the fixed disk 11 is used to connect with the first external component, the rotating disk 12 is rotatably disposed on the fixed disk 11 and is used to connect with the second external component, and the rotating disk 12 can be restricted from detaching from the fixed disk 11 by the clamp 19 disposed on the fixed disk 11.

[0072] Furthermore, a gap 190 is formed between the clamp 19 and the rotating disk 12. A limiting member 191 is disposed on the clamp 19 and is at least partially located within the gap 190, and the limiting member 191 can form sliding friction with the rotating disk 12. That is, through the limiting member 191, the gap 190 between the clamp 19 and the rotating disk 12 can be effectively filled, reducing the possibility of the rotating disk 12 shifting due to the gap 190, and improving the stability and accuracy of the rotation of the rotating disk 12.

[0073] Optionally, refer to Figure 9 and Figure 10 As shown, the limiting member 191 includes a limiting base 1911 and at least one elastic protrusion 1912; the elastic protrusion 1912 is connected to the limiting base 1911, the limiting base 1911 is connected to the clamp 19, the elastic protrusion 1912 is disposed in the gap 190 and protrudes toward the rotating disk 12 to form sliding friction with the rotating disk 12, and the elastic protrusion 1912 can undergo elastic deformation in the first direction A.

[0074] In this embodiment, firstly, by providing the elastic protrusion 1912 that can undergo elastic deformation, even if the gap 190 between the clamp 19 and the rotating disk 12 becomes smaller, the elastic protrusion 1912 can still deform, satisfying the filling and support of the gap 190 between the clamp 19 and the rotating disk 12, reducing the possibility of the rotating disk 12 shifting due to the gap 190, and improving the stability and accuracy of the rotation of the rotating disk 12.

[0075] The limiting base 1911 and the elastic protrusion 1912 can be constructed in any suitable shape and structure, and this disclosure does not limit them. In addition, the limiting base 1911 and the elastic protrusion 1912 can be constructed as an integrally molded structure. For example, the limiting base 1911 and the elastic protrusion 1912 can be integrally molded using POM (Polyoxymethylene) to ensure the wear resistance and self-lubricating properties of the limiting member 191 and extend the service life of the limiting member 191.

[0076] For example, refer to Figure 9 As shown, multiple elastic protrusions 1912 are provided, and the multiple elastic protrusions 1912 are arranged in pairs around the rotating hole 120 at intervals on the limiting base 1911.

[0077] By providing multiple elastic protrusions 1912, the stability of the support of the limiting member 191 can be effectively improved. For example, the elastic protrusion 1912 can be constructed as an elastic sheet that protrudes toward the rotating disk 12 and is capable of elastic deformation.

[0078] Optionally, refer to Figure 9 and Figure 10 As shown, one of the limiting base 1911 and the clamp 19 is provided with at least one snap-fit ​​block 1913, and the other is provided with at least one snap-fit ​​groove 1914, with the snap-fit ​​block 1913 and the snap-fit ​​groove 1914 engaging in corresponding snap-fit ​​cooperation.

[0079] The aforementioned snap-fit ​​grooves 1914 can be multiple, with multiple snap-fit ​​grooves 1914 formed on the limiting base 1911 and corresponding one-to-one with multiple elastic protrusions 1912. Multiple snap-fit ​​blocks 1913 are provided on the clamp 19, and these multiple snap-fit ​​blocks 1913 are correspondingly snapped into the multiple snap-fit ​​grooves 1914, thus enabling the limiting member 191 to be detachably connected to the clamp 19. However, this disclosure does not limit the specific method by which the limiting member 191 is connected to the clamp 19. In other ways, the limiting member 191 can also be connected to the clamp 19 by means of fasteners.

[0080] Additionally, refer to Figure 1As shown, multiple limiting members 191 can be provided, and the multiple limiting members 191 are arranged in pairs at intervals on the clamp 19. This ensures that the multiple limiting members 191 can effectively fill and support the gap 190 at multiple different positions, thereby achieving uniform support for the rotating disk 12 and avoiding tilting of the rotating disk 12 and excessive local stress.

[0081] Optionally, refer to Figure 1 , Figure 5 as well as Figure 6 As shown, the rotating disk 12 includes a rotating disk body 123 and an outer edge 124. The outer edge 124 is connected to the rotating disk body 123 and arranged around the outer periphery of the rotating disk body 123. The rotating disk body 123 is rotatably mounted on the fixed disk 11. The clamp 19 covers the outer edge 124 and forms a gap 190 with it in the first direction A. The limiting member 191 forms sliding friction with the outer edge 124.

[0082] In this embodiment, the clamp 19, by covering the outer edge 124, effectively prevents the rotating disk 12 from slipping off or detaching from the fixed disk 11, thus enhancing safety during use. Furthermore, the gap 190 formed in the first direction A provides space for the outer edge 124 to move, preventing jamming or wear caused by excessive constraint. In addition, the gap 190 allows for thermal expansion and contraction, extending service life. However, this disclosure does not limit the specific structure of the rotating disk 12.

[0083] In one embodiment, reference is made to... Figure 1 , Figure 9 and Figure 10 As shown, the clamp 19 includes a connecting part 192 and a covering part 193 that are connected to each other. The connecting part 192 is connected to the fixed plate 11. The covering part 193 covers the outer edge part 124 in the first direction A, and the covering part 193 and the outer edge part 124 are spaced apart to form a gap 190.

[0084] In this embodiment, the connecting portion 192 is securely connected to the fixed disk 11, and the covering portion 193 can maintain its relative position with the outer edge portion 124 even under vibration or impact conditions. The covering portion 193 and the outer edge portion 124 can be constructed in any suitable shape and structure, and this disclosure does not limit them.

[0085] In another embodiment, reference is made to... Figure 1 and Figure 6 As shown, one of the cover portion 193 and the outer edge portion 124 is provided with a limiting groove 194, and the other is provided with a limiting flange 195. Both the limiting groove 194 and the limiting flange 195 extend around the rotating hole 120, and the limiting flange 195 is rotatably disposed in the limiting groove 194.

[0086] In this embodiment, the sliding of the limiting flange 195 within the limiting groove 194 serves as a constraint and limit, ensuring the rotation of the rotating disk 12 and avoiding problems such as eccentricity and tilting caused by assembly errors or external impacts, thereby improving rotational accuracy. The fit design between the limiting groove 194 and the limiting flange 195 also restricts the radial degree of freedom during rotation; significantly reducing looseness during rotation and making the rotation more reliable and stable.

[0087] Optionally, refer to Figure 3 As shown, the turntable device may also include a ball assembly 27, which includes a ball support 271 and a plurality of balls 272. The balls 272 are rotatably disposed on the ball support 271. The ball support 271 is arranged on the fixed disk 11, and the balls 272 are supported on the fixed disk 11 and on the turntable 12.

[0088] In this embodiment, the ball bearings 272 transmit the load by rolling during rotation, which greatly reduces the frictional resistance between the fixed disk 11 and the rotating disk 12. In addition, multiple balls bearings 272 can be arranged in pairs around the first through hole 1120, which can evenly distribute the load borne by the rotating disk 12 onto each ball bearing 272, thereby improving the load-bearing capacity and anti-eccentric load capacity of the fixed disk 11, reducing wear, and extending service life.

[0089] In another embodiment, refer to Figure 4 As shown, the surfaces of the fixed disk 11 and the rotating disk 12 opposite each other are provided with grooves 214. The grooves 214 are arranged around the first through hole 1120. The ball bearing bracket 271 is arranged in the grooves 214, and the balls 272 are rotatably arranged in the grooves 214.

[0090] In this embodiment, the ball assembly 27 is accommodated by setting a groove 214, eliminating the need for additional external support structures. This simplifies the structure and reduces the size of the space. The balls 272 roll within the groove 214, significantly reducing the rotational resistance between the fixed disk 11 and the rotating disk 12, thus reducing jamming and unevenness. The multiple balls 272 are evenly distributed in the groove 214, ensuring uniform force during rotation and preventing jamming due to excessive local pressure.

[0091] This disclosure also provides a seat (not shown) including a seat body (not shown), a seat slide rail (not shown), and the aforementioned turntable device; wherein, the first external component is constructed as a seat slide rail, and the fixed plate 11 is slidably disposed on the seat slide rail; the second external component is constructed as a seat body.

[0092] This disclosure also provides a vehicle that includes the aforementioned seats.
