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 car. 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, seats also need to have a swivel function to meet the needs of passengers getting in and out.

[0003] In related technologies, the rotation of vehicle seats is often achieved through a turntable structure. However, turntable structures often have problems such as assembly gaps, which can cause the vehicle seats to shift. 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 plate, a rotating plate, at least one clamp and at least one limiting member, the fixed plate being used to connect with a first external component, and the rotating plate being used to connect with a second external component; The rotating disk is rotatably disposed on the fixed disk about a first axis extending along a first direction, and the clamp is connected to the fixed disk 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.

[0006] The fixed disk is used to connect with the first external component, and the rotating disk is rotatably mounted on the fixed disk and used to connect with the second external component. A clamp on the fixed disk prevents the rotating disk from detaching from it. Furthermore, a gap is formed between the clamp and the rotating disk, and a limiting member is disposed on the clamp and at least partially located within this gap, and the limiting member can generate sliding friction with the rotating disk. That is, the limiting member effectively fills the gap between the clamp and the rotating disk, reducing the possibility of the rotating disk shifting due to this gap and improving the stability and accuracy of the rotating disk's rotation.

[0007] 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, and the limiting base is connected to the clamp. The elastic protrusion is disposed within the gap and protrudes toward the rotating disk in the first direction. The elastic protrusion forms sliding friction with the rotating disk and is capable of elastic deformation in the first direction.

[0008] 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.

[0009] In some embodiments, the elastic protrusions are provided in a plurality of positions, and the plurality of elastic protrusions are disposed at intervals around the first axis on the limiting base; One of the limiting base and the clamp is provided with a locking block, and the other is provided with a locking groove, wherein the locking block and the locking groove form a locking engagement.

[0010] By setting multiple elastic protrusions, the stability of the limiting component support can be effectively improved.

[0011] In some embodiments, the limiting member is provided as a plurality of such limiting members, which are arranged at intervals around the first axis on the clamp.

[0012] 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.

[0013] In some embodiments, the fixed disk includes a fixed disk body and a rotating sleeve connected to each other, wherein the axis of the rotating sleeve is the first axis. The rotating disk has a rotating hole, which is rotatably fitted onto the rotating sleeve. The clamp is connected to the fixed disk body and at least partially covers the rotating disk.

[0014] The turntable device further includes a shaft assembly, which is sleeved on the rotating sleeve and located between the rotating hole and the rotating sleeve.

[0015] By incorporating this shaft assembly, the gap between the rotating disk and the rotating sleeve can be reduced, and abnormal noise generated during the rotation of the rotating disk relative to the fixed disk can be eliminated. In addition, this shaft assembly also provides good sealing performance.

[0016] In some embodiments, the rotating disk includes a rotating disk body and an outer edge portion, the outer edge portion being connected to the rotating disk body and arranged around the outer periphery of the rotating disk body, and the rotating disk body being rotatably disposed on the fixed disk; The clamp covers the outer edge and forms a gap with it in the first direction, and the limiting member forms sliding friction with the outer edge.

[0017] The clamp, by covering the outer edge, effectively prevents the rotating disk from slipping off or detaching from the fixed disk, enhancing safety during use. Furthermore, the gap formed in the first direction provides room for movement of the outer edge, preventing jamming or wear caused by excessive constraint. In addition, the gap allows for thermal expansion and contraction, extending service life.

[0018] In some embodiments, the rotating disk body is provided with at least one mounting portion for connection with a first external component.

[0019] The rotating disk body has a mounting part, which facilitates connection with the first external component and provides a basis for the connection.

[0020] In some embodiments, the clamp includes a connecting portion and a covering portion that are connected to each other. The connecting portion is connected to the fixing plate, and the covering portion covers the outer edge portion in the first direction, with the covering portion and the outer edge portion spaced apart to form the gap.

[0021] The cover is securely connected to the fixed plate via the connecting part, and can maintain its relative position to the outer edge even under vibration or impact conditions.

[0022] In some embodiments, one of the covering portion and the outer edge portion is provided with a limiting groove, and the other is provided with a limiting flange. Both the limiting groove and the limiting flange extend around the first axis, and the limiting flange is rotatably disposed in the limiting groove around the first axis.

[0023] The sliding of the limiting flange within the limiting groove serves as a constraint and limit, ensuring that the rotating disk rotates around the first axis. This avoids problems such as eccentricity and tilting caused by assembly errors or external impacts, thus improving rotational accuracy. The fit design between the limiting groove and the limiting flange also restricts the radial degree of freedom during rotation, significantly reducing looseness and making rotation more reliable and stable.

[0024] In some embodiments, the turntable device further includes a locking pin, the turntable having a first locking pin hole and the fixed plate having a second locking pin hole; The locking pin is inserted into the first locking pin hole and can move with the rotating disk. When the first locking pin hole and the second locking pin hole are opposite each other in the first direction, the locking pin can be inserted into the first locking pin hole and the second locking pin hole.

[0025] During the rotation of the rotating disk, the first locking pin hole moves accordingly. When the first locking pin hole aligns with the second locking pin hole, the locking pin can be inserted into the second locking pin hole to lock the rotating disk relative to the fixed disk and prevent the rotating disk from rotating relative to the fixed disk.

[0026] In some embodiments, the surface of the fixed disk opposite to the rotating disk is provided with a sliding groove, the sliding groove is arranged around the first axis, the locking pin is able to slide in the sliding groove, and at least one second locking pin hole is formed in the sliding groove.

[0027] Specifically, a sliding groove is provided on the surfaces of the fixed disk and the rotating disk opposite each other. This sliding groove is arranged around a first axis, allowing the locking pin to slide within it. The sliding groove effectively guides the movement of the locking pin. Furthermore, a second locking pin hole is formed within the sliding groove. When the first and second locking pin holes are aligned, the locking pin is inserted into both the first and second locking pin holes, thus locking the rotating disk relative to the fixed disk and preventing the rotating disk from rotating relative to the fixed disk.

[0028] In some embodiments, the locking pin includes a locking pin rod and a stop rod; The locking pin is used to be inserted into the first locking pin hole and the second locking pin hole; The stop bar is connected to the locking pin at an angle, and the stop bar is used to abut against the rotating disk.

[0029] The design incorporates a stop bar that is angled to the locking pin, which abuts against the rotating disk, thus preventing the locking pin from leaking out through the first and second locking pin holes. When it is necessary to release the relative locking between the rotating disk and the fixed disk, the locking pin can be disengaged from the second locking pin hole.

[0030] In some embodiments, the turntable device further includes a ball assembly, the ball assembly including a ball support and a plurality of balls, the balls being rotatably disposed on the ball support; The ball bearing support is arranged on the fixed plate, and the balls are supported on the fixed plate and the rotating plate.

[0031] The fixed disk and the rotating disk have a recessed groove on their respective surfaces. The groove is arranged around the first axis. The ball bearing bracket is arranged in the groove, and the ball bearing is rotatably disposed in the groove.

[0032] The ball bearing assembly is accommodated by setting a groove, eliminating the need for additional external support structures. This simplifies the structure and reduces the size of the space. The balls roll within the groove, significantly reducing the rotational resistance between the fixed and rotating discs, minimizing jamming and unevenness. Multiple balls are evenly distributed in the groove, ensuring uniform force during rotation and preventing jamming due to excessive local pressure.

[0033] In some embodiments, the fixed disk is provided with a first stop structure, and the rotating disk is provided with at least one second stop structure, wherein the first stop structure can abut against the second stop structure to restrict the rotation of the rotating disk relative to the fixed disk.

[0034] When the aforementioned locking pin is inserted into the first locking pin hole and the second locking pin hole, the first stop structure and the second stop structure can abut against each other, thereby restricting the rotation of the rotating disk relative to the fixed disk and distributing the load to prevent the load from concentrating on one locking pin.

[0035] 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.

[0036] According to a third aspect of the present disclosure, a vehicle is also provided, the vehicle including the aforementioned seat.

[0037] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: a fixed disk is used to connect with a first external component, a rotating disk is rotatably disposed on the fixed disk and used to connect with a second external component, and a clamp disposed on the fixed disk can prevent the rotating disk from detaching from the fixed disk. Furthermore, a gap is formed between the clamp and the rotating disk, a limiting member is disposed on the clamp and at least partially located within the gap, and the limiting member can form 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 shifting due to the gap, and improving the stability and accuracy of the rotating disk's rotation.

[0038] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0048] 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.

[0049] In this disclosure, unless otherwise stated, the directional term "first direction" refers to the thickness direction of the turntable device, 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.

[0050] 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.

[0051] Reference Figures 1 to 7 As shown, this disclosure provides a turntable device, which includes a fixed plate 21, a rotating plate 22, at least one clamp 23 and at least one limiting member 24. The fixed plate 21 is used to connect with a first external component, and the rotating plate 22 is used to connect with a second external component.

[0052] The rotating disk 22 is rotatably disposed on the fixed disk 21 about a first axis a extending along the first direction A. The clamp 23 is connected to the fixed disk 21 and at least partially covers the rotating disk 22 in the first direction A, so as to restrict the rotating disk 22 from detaching from the fixed disk 21 in the first direction A.

[0053] In this configuration, a gap 230 is formed between the clamp 23 and the rotating disk 22 in the first direction A. The limiting member 24 is disposed on the clamp 23 and is at least partially located within the gap 230 to form sliding friction with the rotating disk 22.

[0054] In the above technical solution, the fixed disk 21 is used to connect with the first external component, and the rotating disk 22 is rotatably disposed on the fixed disk 21 and used to connect with the second external component. The clamp 23 disposed on the fixed disk 21 can prevent the rotating disk 22 from detaching from the fixed disk 21. Furthermore, a gap 230 is formed between the clamp 23 and the rotating disk 22. A limiting member 24 is disposed on the clamp 23 and at least partially located within the gap 230, and the limiting member 24 can form sliding friction with the rotating disk 22. That is, through the limiting member 24, the gap 230 between the clamp 23 and the rotating disk 22 can be effectively filled, reducing... The possibility of the rotating disk 22 shifting due to the gap 230 is reduced, thus improving the stability and accuracy of the rotating disk 22.

[0055] Optionally, refer to Figure 1 , Figure 2 as well as Figure 5 As shown, the limiting member 24 includes a limiting base 241 and at least one elastic protrusion 242. The elastic protrusion 242 is connected to the limiting base 241, and the limiting base 241 is connected to the clamp 23. The elastic protrusion 242 is disposed in the gap 230 and protrudes towards the rotating disk 22 in the first direction A. The elastic protrusion 242 forms sliding friction with the rotating disk 22 and can undergo elastic deformation in the first direction A.

[0056] In this embodiment, firstly, by providing the elastic protrusion 242 that can undergo elastic deformation, even if the gap 230 between the clamp 23 and the rotating disk 22 becomes smaller, the elastic protrusion 242 can still deform, satisfying the filling and support of the gap 230 between the clamp 23 and the rotating disk 22, reducing the possibility of the rotating disk 22 shifting due to the gap 230, and improving the stability and accuracy of the rotation of the rotating disk 22.

[0057] The limiting base 241 and the elastic protrusion 242 can be constructed in any suitable shape and structure, and this disclosure does not limit them. In addition, the limiting base 241 and the elastic protrusion 242 can be constructed as an integrally molded structure. For example, the limiting base 241 and the elastic protrusion 242 can be integrally molded using POM (Polyoxymethylene) to ensure the wear resistance and self-lubricating properties of the limiting member 24 and extend the service life of the limiting member 24.

[0058] In another embodiment, refer to Figure 5 As shown, multiple elastic protrusions 242 are provided, and the multiple elastic protrusions 242 are arranged in pairs around the first axis a on the limiting base 241; one of the limiting base 241 and the clamp 23 is provided with a locking block 100, and the other is provided with a locking groove 200, and the locking block 100 and the locking groove 200 form a locking engagement.

[0059] In this embodiment, by providing multiple elastic protrusions 242, the stability of the limiting member 24 can be effectively improved. For example, the elastic protrusion 242 can be constructed as an elastic sheet that rotates toward the rotating disk 22 and can undergo elastic deformation. Multiple slots 200 can be provided, formed on the limiting base 241 and corresponding one-to-one with the multiple elastic protrusions 242. Multiple locking blocks 100 are provided on the clamp 23, and these locking blocks 100 are correspondingly engaged within the multiple slots 200, enabling the limiting member 24 to be detachably connected to the clamp 23. However, this disclosure does not limit the specific method by which the limiting member 24 is connected to the clamp 23. In other ways, the limiting member 24 can also be connected to the clamp 23 by fasteners.

[0060] Optionally, refer to Figure 1 As shown, multiple limiting members 24 are provided, and the multiple limiting members 24 are arranged in pairs around the first axis a on the clamp 23. This ensures that the multiple limiting members 24 can effectively fill and support the gap 230 at multiple different positions, thereby achieving uniform support for the rotating disk 22 and avoiding tilting of the rotating disk 22 and excessive local stress.

[0061] In another embodiment, refer to Figure 3 As shown, the fixed disk 21 may include a fixed disk body 211 and a rotating sleeve 212 connected to each other, and the axis of the rotating sleeve 212 is the first axis a; the rotating disk 22 has a rotating hole 220, which is rotatably fitted onto the rotating sleeve 212, and the clamp 23 is connected to the fixed disk body 211 and at least partially covers the rotating disk 22.

[0062] In this embodiment, firstly, the rotating disk 22 is rotatably fitted onto the rotating sleeve 212 through the rotating hole 220 on the rotating disk 22, thereby enabling the rotating disk 22 to rotate relative to the fixed disk 21. Secondly, the clamp 23 is connected to the fixed disk body 211, and the connection can be made in any suitable manner, for example, by using a fastener connection.

[0063] In addition, the clamp 23 at least partially covers the rotating disk 22, which can limit the rotating disk 22 and prevent the rotating disk 22 from detaching from the fixed disk 21 in the first direction A. However, this disclosure does not limit the specific structure of the fixed disk 21 and the rotating disk 22.

[0064] Furthermore, this disclosure does not limit the rotation form of the rotating disk 22 and the fixed disk 21. In other embodiments, the fixed disk 21 may have a fixed disk hole (not shown), and the rotating disk 22 may be provided with a rotating disk sleeve, which is rotatably disposed in the fixed disk hole, thus enabling rotation between the two.

[0065] Optionally, refer to Figure 3 As shown, the turntable device also includes a shaft assembly 25, which is sleeved on the rotating sleeve 212 and located between the rotating hole 220 and the rotating sleeve 212.

[0066] By providing the shaft assembly 25, the gap between the rotating disk 22 and the rotating sleeve 212 can be reduced, and abnormal noise generated during the rotation of the rotating disk 22 relative to the fixed disk 21 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.

[0067] In other implementations, refer to Figure 2 , Figure 4 as well as Figure 5 As shown, the rotating disk 22 includes a rotating disk body 221 and an outer edge 222. The outer edge 222 is connected to the rotating disk body 221 and arranged around the outer periphery of the rotating disk body 221. The rotating disk body 221 is rotatably mounted on the fixed disk 21. The clamp 23 covers the outer edge 222 and forms a gap 230 with it in the first direction A. The limiting member 24 forms sliding friction with the outer edge 222.

[0068] In this embodiment, the clamp 23, by covering the outer edge 222, effectively prevents the rotating disk 22 from slipping off or detaching from the fixed disk 21, thus enhancing safety during use. Furthermore, the gap 230 formed in the first direction A provides space for the outer edge 222 to move, preventing jamming or wear caused by excessive constraint. In addition, the gap 230 allows for thermal expansion and contraction, extending service life. However, this disclosure does not limit the specific structure of the rotating disk 22.

[0069] Optionally, refer to Figure 1 As shown, the rotating disk body 211 is provided with at least one mounting part 2111, which is used to connect with the first external component.

[0070] In this embodiment, by providing a mounting portion 2111 on the rotating disk body 211, it is convenient to connect with the first external component, providing a basis for the connection. The mounting portion 2111 can be constructed as any suitable mounting structure, and this disclosure does not limit it. For example, the mounting portion 2111 can be a mounting nut, which can be fixed to the rotating disk body 211, and multiple mounting nuts can be provided, with multiple mounting nuts arranged in pairs around the first axis a.

[0071] In one embodiment, reference is made to... Figure 1 , Figure 5 as well as Figure 6 As shown, the clamp 23 includes a connecting part 231 and a covering part 232 that are connected to each other. The connecting part 231 is connected to the fixed plate 21. The covering part 232 covers the outer edge 222 in the first direction A, and the covering part 232 and the outer edge 222 are spaced apart to form a gap 230.

[0072] In this embodiment, the connecting portion 231 is securely connected to the fixed disk 21, and even under vibration or impact conditions, the covering portion 232 can maintain its relative position with the outer edge portion 222. The covering portion 232 and the outer edge portion 222 can be constructed in any suitable shape and structure, and this disclosure does not limit them.

[0073] In another embodiment, reference is made to... Figure 1 , Figure 4 as well as Figure 6 As shown, one of the cover portion 232 and the outer edge portion 222 is provided with a limiting groove 233, and the other is provided with a limiting flange 234. Both the limiting groove 233 and the limiting flange 234 extend around the first axis a, and the limiting flange 234 is rotatably disposed in the limiting groove 233 around the first axis a.

[0074] In this embodiment, the sliding of the limiting flange 234 within the limiting groove 233 serves as a constraint and limit, ensuring that the rotating disk 22 rotates around the first axis a; this avoids problems such as eccentricity and tilting caused by assembly errors or external impacts, thus improving rotational accuracy. The fit design between the limiting groove 233 and the limiting flange 234 also restricts the radial degree of freedom during rotation; significantly reducing looseness during rotation and making the rotation more reliable and stable.

[0075] Optionally, refer to Figure 1 Figure 2 as well as Figure 4 As shown, the turntable device also includes a locking pin 26. The rotating disk 22 has a first locking pin hole 260, and the fixed disk 21 has a second locking pin hole 270. The locking pin 26 is inserted into the first locking pin hole 260 and can move with the rotating disk 22. When the first locking pin hole 260 and the second locking pin hole 270 are opposite to each other in the first direction A, the locking pin 26 can be inserted into the first locking pin hole 260 and the second locking pin hole 270.

[0076] In this embodiment, as the rotating disk 22 rotates, the first locking pin hole 260 moves accordingly. When the first locking pin hole 260 aligns with the second locking pin hole 270 on the fixed disk 21, the locking pin 26 can be inserted into the second locking pin hole 270 to lock the rotating disk 22 relative to the fixed disk 21 and prevent the rotating disk 22 from rotating relative to the fixed disk 21.

[0077] Optionally, refer to Figure 3 As shown, the surfaces of the fixed disk 21 and the rotating disk 22 opposite each other are provided with a sliding groove 213. The sliding groove 213 is arranged around the first axis a. The locking pin 26 can slide in the sliding groove 213, and at least one second locking pin hole 270 is formed in the sliding groove 213.

[0078] That is, in this embodiment, by providing a sliding groove 213 on the surfaces of the fixed disk 21 and the rotating disk 22 opposite to each other, and the sliding groove 213 being arranged around the first axis a, the locking pin 26 can slide within the sliding groove 213, and the sliding groove 213 can effectively guide the movement of the locking pin 26. In addition, a second locking pin hole 270 is formed in the sliding groove 213. When the first locking pin hole 260 and the second locking pin hole 270 are opposite to each other, the locking pin 26 is inserted into both the first locking pin hole 260 and the second locking pin hole 270, thereby locking the rotating disk 22 relative to the fixed disk 21 and preventing the rotating disk 22 from rotating relative to the fixed disk 21.

[0079] Reference Figure 1 and Figure 2 As shown, the locking pin 26 includes a locking pin rod 261 and a stop rod 262; the locking pin rod 261 is used to be inserted into the first locking pin hole 260 and the second locking pin hole 270; the stop rod 262 is connected to the locking pin rod 261 at an angle and is used to abut against the rotating disk 22.

[0080] In this embodiment, by providing a stop bar 262 that is angledly connected to the locking pin 261, the stop bar 262 can abut against the rotating disk 22, thereby preventing the locking pin 261 from leaking out through the first locking pin hole 260 and the second locking pin hole 270. When it is necessary to release the relative locking between the rotating disk 22 and the fixed disk 21, the locking pin 26 can be disengaged from the second locking pin hole 270. Furthermore, this disclosure does not limit the number of second locking pin holes 270. For example, there can be two second locking pin holes 270, and the two second locking pins 270 can be arranged centrally symmetrically. However, this disclosure does not limit the number or position of the second locking pin holes 270.

[0081] Optionally, refer to Figure 3 As shown, the turntable device also includes a ball assembly 27, which includes a ball support 271 and a plurality of balls 272. The balls 272 are rotatably mounted on the ball support 271. The ball support 271 is arranged on the fixed disk 21, and the balls 272 are supported on the fixed disk 21 and on the turntable 22.

[0082] In this embodiment, the ball bearings 272 transmit the load by rolling during rotation, which greatly reduces the frictional resistance between the fixed disk 21 and the rotating disk 22. In addition, multiple balls bearings 272 can be arranged in pairs around the first axis a, which can evenly distribute the load borne by the rotating disk 22 to each ball bearing 272, improve the load-bearing capacity and anti-eccentric load capacity of the fixed disk 21, reduce wear, and extend service life.

[0083] In another embodiment, refer to Figure 3 As shown, the surfaces of the fixed disk 21 and the rotating disk 22 opposite each other are provided with grooves 214. The grooves 214 are arranged around the first axis a. The ball bearing bracket 271 is arranged in the grooves 214, and the balls 272 are rotatably arranged in the grooves 214.

[0084] 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 21 and the rotating disk 22, 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.

[0085] Optionally, refer to Figures 2 to 4 As shown, the fixed disk 21 is provided with a first stop structure 215, and the rotating disk 22 is provided with at least one second stop structure 216. The first stop structure 215 can abut against the second stop structure 216 to restrict the rotating disk 22 from rotating relative to the fixed disk 21.

[0086] In this embodiment, when the locking pin 26 is inserted into the first locking pin hole 260 and the second locking pin hole 270, the first stop structure 215 and the second stop structure 216 can abut against each other, thereby restricting the rotation of the rotating disk 22 relative to the fixed disk 21 and distributing the load to prevent the load from concentrating on the locking pin 26.

[0087] Additionally, refer to Figure 7 As shown, the rotating disk 22 has a recessed mounting groove 223 around the rotating hole 220. The protective sleeve 28 includes an annular sleeve, which includes an annular sleeve body 281, a first annular flange 282, and a second annular flange 283. The first annular flange 282 and the second annular flange 283 are respectively connected to the two sides of the annular sleeve body 281. The first annular flange 282 is disposed opposite to at least a portion of the inner wall of the rotating sleeve 212, and the second annular flange 283 is disposed opposite to at least a portion of the outer wall of the rotating sleeve 212. The second annular flange 283 is connected to the groove wall of the mounting groove 223.

[0088] In this embodiment, firstly, the annular sleeve body 281 is positioned opposite to the end edge of the rotating sleeve 212, effectively protecting the end edge. The first annular flange 282 protects the inner wall of the rotating sleeve 212, and the second annular flange 283 protects the outer wall of the rotating sleeve 212. When the wire harness needs to pass through the sleeve through hole 2120 of the rotating sleeve 212, the wire harness can pass through the through hole 280 of the protective sleeve 28. The smooth protective sleeve 28 can effectively protect the wire harness, preventing the end edge of the rotating sleeve 212 from wearing or cutting the wire harness, extending its service life, and improving safety.

[0089] In addition, the connection between the second annular flange 283 and the groove wall of the mounting groove 223 can be made in any appropriate way. For example, multiple mounting blocks 2831 can be provided on the second annular flange 283, and multiple mounting slots 2832 can be provided on the groove wall of the mounting groove 223. The mounting blocks 2831 are engaged in the mounting slots 2832 to realize the installation of the protective sleeve 28.
