Figure 2In the embodiment, the latching member 40 in the turntable assembly 100 is in a locked position.

[0033] The embodiment of the present application provides a robot, which includes a body and a turntable assembly 100. The turntable assembly 100 is mounted on the body. The turntable assembly 100 includes a driver 10, a mounting structure 21, a turntable 30 and a clamping member 40. The driver 10 is fixedly mounted on the body. The driver 10 is used to drive the turntable 30 to rotate. The driver 10 is provided with an output shaft 11. The mounting structure 21 is fixedly connected to the output shaft 11. A first clamping groove 301 is provided on the turntable 30. The clamping member 40 can be movably mounted in the mounting structure 21. The clamping member 40 has a locking position and an unlocking position relative to the mounting structure 21. When the clamping member 40 moves to the locking position relative to the mounting structure 21, the clamping member 40 is clamped in the first clamping groove 301, and the turntable 30 is fixed relative to the mounting structure 21. When the clamping member 40 moves to the unlocked position relative to the mounting structure 21, the clamping member 40 is located outside the first clamping groove 301, and the rotating disk 30 is movable relative to the mounting structure 21 along the first direction D1. The first direction D1 is the direction in which the rotating disk 30 moves away from the mounting structure 21. When the clamping member 40 is in the unlocked position, when the rotating disk 30 moves along the first direction D1 (i.e., along the Figure 2 When the turntable 30 moves in the direction of the arrow D1 in the first direction (i.e., moves in the direction of the arrow D1 in the second direction), the turntable 30 and the mounting structure 21 can be separated from each other. Figure 2 When the rotating disk 30 moves in the opposite direction of the arrow D1 in the figure, the rotating disk 30 can be moved to the position where the rotating disk 30 is located when the clamping member 40 is clamped in the first clamping groove 301.

[0034] In the embodiment of the present application, through the cooperation between the clamping member 40 and the mounting structure 21, when the clamping member 40 moves to the locked position, the clamping member 40 is partially clamped in the first clamping groove 301, and the turntable 30 is fixed relative to the mounting structure 21, thereby achieving the fixed connection of the turntable 30 to the mounting structure 21; when the clamping member 40 moves to the unlocked position, the clamping member 40 is located outside the first clamping groove 301, and the turntable 30 is movable along the first direction D1 relative to the mounting structure 21, thereby achieving the turntable 30 being removable from the mounting structure 21, thereby achieving quick disassembly and installation between the turntable 30 and the mounting structure 21, reducing the difficulty of disassembly and assembly between the turntable 30 and the mounting structure 21, and simplifying the disassembly and assembly process.

[0035] Figure 1 The purpose of the present invention is only to schematically describe the structure of the turntable assembly 100, and does not constitute a specific limitation on the turntable assembly 100. In some other embodiments of the present application, the turntable assembly 100 may include: Figure 1 More or fewer mechanisms as shown, or a combination of certain mechanisms, or different mechanisms, for example, the turntable assembly 100 may also include but is not limited to a power supply, a controller, and the like.

[0036] See also Figure 1 For example, in this embodiment, the robot can be configured as a cutting robot. The cutting robot is used to mow the lawn. The rotating disk 30 is configured as a knife disk, and a cutting piece is arranged on the knife disk. When the driver 10 drives the knife disk to rotate through the mounting structure 21 and the clamping member 40, the knife disk drives the cutting piece to move, so that the cutting piece mows the lawn.

[0037] See also Figure 4 , Figure 4 is a cross-sectional view of the turntable assembly provided in some embodiments of the present application. In some embodiments, the robot can also be configured as a cleaning robot. The cleaning robot is used to clean the ground. The turntable 30 is configured as a cleaning disk, and a cleaning brush is provided on the cleaning disk. When the driver 10 drives the cleaning disk to rotate through the mounting structure 21 and the clamping member 40, the cleaning disk drives the cleaning brush to move, and the cleaning brush cleans up garbage, fallen leaves and other debris on the ground, or scrubs stains on the ground. In some embodiments, the robot can also be configured as other types of robots, and the structure of the turntable 30 is specifically set according to the type of robot.

[0038] Please also read Figure 1 , Figure 2 and Figure 3 , the clamping member 40 is movably arranged relative to the mounting structure 21 along the second direction D2. The locking position and the unlocking position are arranged at intervals along the second direction D2. When the clamping member 40 moves along the second direction D2, the clamping member 40 can enter the first clamping groove 301 or disengage from the first clamping groove 301. Among them, the second direction D2 is arranged at an angle to the first direction D1. Exemplarily, the first direction D1 and the second direction D2 can be arranged at a right angle. In some embodiments, the first direction D1 and the second direction D2 can also be arranged at an acute angle or an obtuse angle. The angle between the second direction D2 and the first direction D1 can be specifically set according to actual needs, and is not specifically limited in this application.

[0039] The mounting structure 21 is provided with a through hole 2101. The through hole 2101 is extended along the second direction D2. The clamping member 40 is movably disposed in the through hole 2101. The turntable assembly 100 also includes a pressing structure 221. The pressing structure 221 is movably mounted in the mounting structure 21. The movable direction of the pressing structure 221 relative to the mounting structure 21 can be parallel to the first direction D1. In some embodiments, the movable direction of the pressing structure 221 relative to the mounting structure 21 can also be arranged at an angle to the first direction D1.

[0040] The pressing structure 221 has a first position and a second position different from the first position relative to the mounting structure 21. Figure 2In the embodiment, the pressing structure 221 is in the first position relative to the mounting structure 21. When the pressing structure 221 is in the first position, the pressing structure 221 abuts against the clamping member 40, and the clamping member 40 is in the locking position. At this time, since the pressing structure 221 abuts against the clamping member 40, the clamping member 40 can be kept clamped in the first clamping groove 301, thereby fixing the rotating disk 30 and the mounting structure 21 together.

[0041] exist Figure 3 In the embodiment, the pressing structure 221 is in the second position relative to the mounting structure 21. When the pressing structure 221 is in the second position, the clamping member 40 is movable in the through hole 2101 and can be moved to the unlocking position. At this time, since the clamping member 40 is movable, the rotating disk 30 can move along the first direction D1. When the rotating disk 30 moves to separate from the mounting structure 21, the rotating disk 30 pushes the clamping member 40 to move to the unlocking position. When the clamping member 40 moves to the unlocking position, the pressing structure 221 abuts against the clamping member 40 to prevent the clamping member 40 from falling out of the through hole 2101.

[0042] The clamping member 40 is configured as at least one of a spherical structure, a cylindrical structure, a prismatic structure, a hemispherical structure, a semi-cylindrical structure, and a semi-prismatic structure, or a combination of at least two thereof. Exemplarily, in this embodiment, the clamping member 40 may be configured as a spherical structure, and the clamping member 40 may be configured as a ball. In some embodiments, the clamping member 40 may also be configured as a combination of a spherical structure and a cylindrical structure, for example, the clamping member 40 may be configured as a capsule structure, a rugby-shaped structure, etc. In some embodiments, the clamping member 40 may also be configured as other structures.

[0043] The turntable assembly 100 also includes a first elastic member 222. The first elastic member 222 is located between the pressing structure 221 and the mounting structure 21. The mounting structure 21 includes a side plate 211 and an end plate 212. The side plate 211 is arranged in a ring shape. The end plate 212 is connected to the end of the side plate 211 along the first direction D1. The side plate 211 and the end plate 212 enclose a movable groove 2102. The through hole 2101 is arranged on the side plate 211 and is connected to the movable groove 2102. The pressing structure 221 and the first elastic member 222 are movably arranged in the movable groove 2102 and are movable in the movable groove 2102 along the first direction D1. When the pressing structure 221 is located in the first position, the pressing structure 221 is located at the end of the side plate 211 away from the end plate 212. When the pressing structure 221 is located in the second position, the pressing structure 221 is located at the end of the side plate 211 close to the end plate 212.

[0044] The first elastic member 222 can be configured as a spring, a torsion spring, a spring sheet or other elastic elements. The first elastic member 222 is used to reset the pressing structure 221, so that the pressing structure 221 is reset from the second position to the first position, so that when the first clamping groove 301 is aligned with the through hole 2101, the clamping member 40 is automatically pushed from the unlocking position to the locking position. When the clamping member 40 is clamped in the first clamping groove 301, the elastic force provided by the first elastic member 222 can also keep the pressing structure 221 in the first position, avoiding the pressing structure 221 from being pressed by mistake, thereby improving the reliability and safety of the turntable assembly 100.

[0045] The turntable 30 includes a disk body 31 and a connecting portion 32. The disk body 31 is arranged roughly in a disk shape. The thickness direction of the disk body 31 is parallel to or roughly parallel to the first direction D1. The connecting portion 32 is connected to the disk body 31 and is protruded relative to the disk body 31 along the first direction D1. The connecting portion 32 is provided with a connecting hole 321 opened along the first direction D1. When the turntable 30 is fixed relative to the mounting structure 21, the mounting structure 21 is penetrated in the connecting hole 321.

[0046] The connecting hole 321 is connected to the first clamping groove 301. The first clamping groove 301 is provided on the hole wall of the connecting hole 321. In this embodiment, the first clamping groove 301 may be a blind hole provided on the connecting portion 32, and the first clamping groove 301 does not penetrate the connecting portion 32. In some embodiments, the first clamping groove 301 may also be a through hole provided on the connecting portion 32, and the first clamping groove 301 penetrates the connecting portion 32.

[0047] When the turntable 30 needs to be disassembled, the user can press the pressing structure 221 to move the pressing structure 221 from the first position to the second position and compress the first elastic member 222. At this time, the clamping member 40 can move to the unlocking position in the through hole 2101, so that the turntable 30 can move relative to the mounting structure 21 along the first direction D1, that is, the turntable 30 can be removed from the mounting structure 21. When the turntable 30 needs to be installed, the user can align the connecting hole 321 of the turntable 30 with the side panel 211 of the mounting structure 21 so that the side panel 211 is inserted into the connecting hole 321. When the first snap-in groove 301 is aligned with the through hole 2101, the pressing structure 221 moves from the second position to the first position under the action of the elastic force of the first elastic member 222. When the pressing structure 221 moves, it pushes the snap-in member 40 from the unlocking position to the locking position, so that the snap-in member 40 is snapped into the first snap-in groove 301, thereby fixing the turntable 30 and the mounting structure 21 together.

[0048] In this embodiment, the end plate 212 is used to be fixedly connected to the output shaft 11. A mounting portion 213 may be convexly provided on the side of the end plate 212 away from the side plate 211, and a mounting hole 2103 is provided in the mounting portion 213. The output shaft 11 is inserted into the mounting hole 2103 to be fixedly connected to the mounting structure 21 through the mounting portion 213.

[0049] The turntable assembly 100 further includes a pressure block 231 and a second elastic member 232. When the turntable 30 is fixed to the mounting structure 21, the mounting structure 21 is inserted into the connection hole 321, the turntable 30 abuts against the pressure block 231, and the second elastic member 232 elastically abuts against a side of the pressure block 231 away from the turntable 30. The second elastic member 232 can be configured as a spring, a torsion spring, a spring sheet or other elastic elements.

[0050] The pressing block 231 has a third position and a fourth position different from the third position relative to the mounting structure 21. The second elastic member 232 is used to reset the pressing block 231, so that the pressing block 231 is reset from the third position to the fourth position. Figure 2 In the embodiment, the pressing block 231 is in the third position relative to the mounting structure 21, and the connecting portion 32 of the rotating disk 30 pushes the pressing block 231 to a position where the side plate 211 is relatively close to one end of the end plate 212, and the pressing block 231 puts the second elastic member 232 in a compressed state. Figure 3 In the embodiment, the pressing block 231 is in the fourth position relative to the mounting structure 21. Under the elastic restoring force of the second elastic member 232, the pressing block 231 moves toward the end of the side plate 211 relatively away from the end plate 212. The pressing block 231 pushes the turntable 30 to separate from the mounting structure 21, thereby realizing the automatic ejection of the turntable 30, simplifying the disassembly process of the turntable 30, and facilitating the rapid disassembly of the turntable 30. In addition, when the clamping member 40 is clamped in the first clamping groove 301, the elastic force provided by the second elastic member 232 to the turntable 30 through the pressing block 231 can also keep the groove wall of the first clamping groove 301 in contact with the clamping member 40, reducing or avoiding the loosening of the turntable 30 relative to the mounting structure 21, improving the rotation stability of the turntable 30 during rotation, reducing structural wear, and increasing the service life.

[0051] In the embodiment of the present application, based on the mutual cooperation of the mounting structure 21, the clamping part 40, the pressing structure 221, the first elastic part 222, the pressing block 231 and the second elastic part 232, the user can align the connecting part 32 of the turntable 30 with the mounting structure 21 and insert them to quickly fix the turntable 30 and the mounting structure 21 together. The turntable 30 can be popped out by pressing the pressing structure 221, and the turntable 30 can be quickly disassembled, thereby greatly simplifying the disassembly and assembly process of the turntable 30, reducing the difficulty of disassembly and assembly of the turntable 30, improving the convenience of using the robot, and enhancing the user experience of the robot.

[0052] At least one of the pressing block 231, the first clamping groove 301, and the pressing structure 221 is provided with a guide surface 201. The guide surface 201 is used to abut against the clamping member 40. The guide surface 201 is set at an acute angle with the second direction D2. When the pressing block 231, the turntable 30, or the pressing structure 221 moves along the first direction D1, when the guide surface 201 pushes against the clamping member 40, the guide surface 201 will generate a component force along the second direction D2 on the clamping member 40, which is conducive to pushing the clamping member 40 to move along the through hole 2101, avoiding the problem of structural jamming, and is conducive to improving the reliability of the turntable assembly 100.

[0053] The guide surface 201 and the outer surface of the clamping member 40 may be in arc contact, reducing the friction between the guide surface 201 and the clamping member 40, so as to facilitate the guide surface 201 to push the clamping member 40 to move in the through hole 2101. At least one of the guide surface 201 and the outer surface of the clamping member 40 is configured as an arc surface.

[0054] In some embodiments, a guide surface 201 is provided at the end of the pressing block 231 close to the rotating disk 30. The guide surface 201 is connected between a side surface of the pressing block 231 facing the rotating disk 30 and a side surface facing the mounting structure 21. When the pressing block 231 moves from the third position to the fourth position, the guide surface 201 helps to reduce the difficulty of the pressing block 231 pushing the clamping member 40 to move from the locked position to the unlocked position.

[0055] In some embodiments, a guide surface 201 is provided on one side of the first clamping groove 301 close to the pressing block 231, and the guide surface 201 is connected between the groove wall of the first clamping groove 301 close to the pressing block 231 and the hole wall of the connecting hole 321 facing the mounting structure 21. When the rotating disk 30 moves along the first direction D1, the guide surface 201 in the first clamping groove 301 can push the clamping member 40 to move along the second direction D2, which is conducive to moving the clamping member 40 out of the first clamping groove 301 and facilitating the pressing block 231 to eject the rotating disk 30.

[0056] In some embodiments, two guide surfaces 201 are provided in the first clamping groove 301. A guide surface 201 may be provided on the side of the first clamping groove 301 away from the pressing block 231, and the guide surface 201 is connected between the groove wall of the first clamping groove 301 away from the pressing block 231 and the hole wall of the connecting hole 321 facing the mounting structure 21. The two guide surfaces 201 in the first clamping groove 301 may be symmetrically arranged so that the clamping member 40 can be more firmly clamped in the first clamping groove 301, thereby improving the stability and reliability of the connection between the turntable 30 and the mounting structure 21.

[0057] In some embodiments, a guide surface 201 is provided at the end of the pressing structure 221 away from the end plate 212. The guide surface 201 is connected between a surface of the pressing structure 221 facing the side plate 211 and a surface of the pressing structure 221 facing away from the end plate 212. When the pressing structure 221 moves from the first position to the second position, the guide surface 201 helps to reduce the difficulty of the pressing structure 221 in pushing the clamping member 40 to move from the unlocking position to the locking position, so that when the first clamping groove 301 is aligned with the through hole 2101, the clamping member 40 is quickly pushed to be clamped in the first clamping groove 301, thereby improving the installation efficiency of the turntable 30. In addition, the guide surface 201 can also provide an escape space for the snap-in component 40, so that when the snap-in component 40 moves to the unlocked position, the side of the snap-in component 40 close to the connecting portion 32 is immersed in the through hole 2101, that is, the snap-in component 40 is completely moved out of the first snap-in groove 301, thereby preventing the turntable 30 from being blocked from popping out, thereby allowing the turntable 30 and the mounting structure 21 to be smoothly separated.

[0058] In some embodiments, the connecting portion 32 is provided with a guide surface 201. The guide surface 201 is connected between the surface of the connecting portion 32 on the side away from the disk body 31 and the hole wall of the connecting hole 321. When the connecting portion 32 pushes the pressing block 231 to move in the opposite direction of the first direction D1, the guide surface 201 helps to prevent the clamping member 40 from clamping the connecting portion 32, thereby facilitating the connecting portion 32 to be sleeved outside the mounting structure 21, thereby facilitating the fixing of the turntable 30 to the mounting structure 21.

[0059] The turntable assembly 100 also includes a cover 24. The cover 24 is fixedly connected to the mounting structure 21, and encloses the mounting structure 21 to form an accommodating space 240. The accommodating space 240 is extended along the first direction D1. The pressing block 231 and the second elastic member 232 are both located in the accommodating space 240. In this way, on the one hand, the cover 24 can protect the pressing block 231 and the second elastic member 232 to prevent foreign objects from getting stuck in the second elastic member 232 or between the second elastic member 232 and the pressing block 231, and prevent users from misoperating the pressing block 231 and the second elastic member 232, thereby avoiding structural failures and improving the reliability of the turntable assembly 100. On the other hand, the cover 24 can also guide the movement of the pressing block 231 to move the pressing block 231 along the first direction D1. Among them, when the turntable 30 is fixed relative to the mounting structure 21, the connecting portion 32 extends into the accommodating space 240.

[0060] In this embodiment, the pressing block 231 can be configured as an annular structure, and the pressing block 231 is sleeved outside the mounting structure 21. In this way, the pressing block 231 can move smoothly in the accommodating space 240 to avoid the problem of being stuck. In some embodiments, the pressing block 231 can also be configured as a block structure, and a plurality of pressing blocks 231 can be provided, and the plurality of pressing blocks 231 are arranged around the outer peripheral side of the mounting structure 21.

[0061] The cover shell 24 and the mounting structure 21 may be separately provided and fixedly connected together by bonding, clamping, welding, threaded connection, screw connection, etc., or the cover shell 24 and the mounting structure 21 may be integrally formed. Exemplarily, in this embodiment, the cover shell 24 and the mounting structure 21 are separately provided, and the cover shell 24 is fixedly connected to the end plate 212. Among them, fixing holes 2411 may be provided between the cover shell 24 and the mounting structure 21, and the turntable assembly 100 also includes screws, which are inserted into the fixing holes 2411 and fixedly connected to the cover shell 24 and the mounting structure 21.

[0062] In this embodiment, the cover shell 24 includes a first shell portion 241 and a second shell portion 242. The first shell portion 241 is used to be fixedly connected to the end plate 212. The fixing hole 2411 and the avoidance hole are respectively arranged on the first shell portion 241. The second shell portion 242 is arranged in an annular shape. The first shell portion 241 is fixedly connected to the end of the second shell portion 242 close to the end plate 212. The second elastic member 232 and the pressing block 231 are located between the second shell portion 242 and the side plate 211. Along the second direction D2, the first shell portion 241 is protruded relative to the mounting structure 21. On the projection plane perpendicular to the first direction D1, the orthographic projection of the first shell portion 241 protrudes beyond the orthographic projection of the mounting structure 21. The two ends of the second elastic member 232 are respectively abutted against the pressing block 231 and the first shell portion 241. Among them, the first shell portion 241 and the second shell portion 242 can be integrally formed or separately arranged.

[0063] See also Figure 5 , Figure 5 is a cross-sectional view of a turntable assembly provided in some embodiments of the present application. Figure 5 The structure of the turntable assembly in the embodiment is similar to that of the turntable assembly 100 in the above embodiment, except that the cover 24 is configured as a first shell portion 241, and the cover 24 does not include a second shell portion 242. The pressing block 231 is constructed as an annular structure and is sleeved on the mounting structure 21.

[0064] See also Figure 3 In some embodiments, the turntable assembly 100 further includes a stopper 214. The stopper 214 is fixedly connected to the mounting structure 21 and is used to stop the pressing structure 221 in the movable groove 2102 to prevent the pressing structure 221 from being separated from the movable groove 2102. The stopper 214 is detachably connected to the mounting structure 21 to facilitate the installation of the pressing structure 221 in the movable groove 2102.

[0065] Exemplarily, the limiting member 214 can be arranged to be snap-fitted with the mounting structure 21. A slot is provided at the end away from the end plate 212 on the side wall of the side plate 211 of the mounting structure 21 facing the inside of the movable groove 2102. The limiting member 214 is snap-fitted into the slot and protrudes relative to the side plate 211 toward the inside of the movable groove 2102. When the pressing structure 221 moves to the first position, the limiting member 214 abuts against the pressing structure 221 to prevent the pressing structure 221 from moving outside the movable groove 2102. Among them, a groove 2141 is provided at one end of the side plate 211 away from the end plate 212. A protrusion 2142 is convexly provided in the groove 2141 along the second direction D2. The protrusion 2142 and the groove wall of the groove 2141 close to the end plate 212 are enclosed to form a slot. The limiting member 214 can be constructed as a strip structure extending in an arc shape so as to be firmly snapped into the slot. In some embodiments, the stopper 214 may be fixedly connected to the mounting structure 21 by bonding, welding, screwing, etc. In some embodiments, the stopper 214 may be configured as other structures, such as a screw.

[0066] In some embodiments, when the pressing structure 221 moves to the second position and contacts the stopper 214, the end of the pressing structure 221 that is away from the first elastic member 222 is located inside the movable groove 2102, that is, the pressing structure 221 does not protrude outside the movable groove 2102. The surface of the pressing structure 221 that is away from the end plate 212 is flush with the end surface of the side plate 211 that is away from the end plate 212, or the surface of the pressing structure 221 that is away from the end plate 212 is located on the side of the end surface of the side plate 211 that is away from the end plate 212 that is close to the end plate 212. In this way, the risk of the pressing structure 221 being pressed by an external object and being pressed by mistake can be reduced, and the turntable 30 can be prevented from being accidentally disassembled.

[0067] See also Figure 2 , Figure 6 and Figure 7 , Figure 6 is a schematic diagram of the structure of the installation structure 21 provided in the embodiment of the present application, Figure 7: is a schematic diagram of the structure of the turntable 30 provided in an embodiment of the present application. In some embodiments, one of the mounting structure 21 and the turntable 30 is provided with a limiting portion 215, and the other of the mounting structure 21 and the turntable 30 is provided with a second clamping groove 302 for cooperating with the limiting portion 215. The extension direction of the second clamping groove 302 is parallel to the first direction D1. In this embodiment, the limiting portion 215 is provided on the mounting structure 21. The limiting portion 215 is convexly arranged on the side of the side plate 211 away from the movable groove 2102. The turntable 30 is provided with a second clamping groove 302, and the second clamping groove 302 is arranged on the hole wall of the connecting hole 321, and passes through the end surface of the connecting portion 32 away from the disk body 31. When the turntable 30 is fixed relative to the mounting structure 21, the limiting portion 215 is located in the second clamping groove 302. The limiting portion 215 and the second clamping groove 302 are used to limit the mutual rotation of the mounting structure 21 and the turntable 30, so as to prevent the turntable 30 from rotating during the process of disassembling and assembling the turntable 30, thereby eliminating safety hazards. In addition, the limiting portion 215 can also limit the movement of the pressing block 231 to prevent the pressing block 231 from moving out of the accommodating space 240.

[0068] Along the circumferential direction of the turntable 30 (the rotation direction of the turntable 30), the width of the second clamping groove 302 at one end away from the disk body 31 is greater than the width of the second clamping groove 302 at one end close to the disk body 31. The second clamping groove 302 is expanded at the end away from the disk body 31, so that when the turntable 30 is installed on the mounting structure 21, it is beneficial to align the limiting portion 215 with the second clamping groove 302, and guide the limiting portion 215, thereby reducing the difficulty of clamping the limiting portion 215 with the second clamping groove 302, thereby reducing the difficulty of installing the turntable 30. In some embodiments, the limiting portion 215 is provided on the hole wall of the connecting hole 321 of the turntable 30, and the second clamping groove 302 is provided on the side wall of the side plate 211 of the mounting structure 21 away from the movable groove 2102, and the second clamping groove 302 can be expanded at one end away from the end plate 212.

[0069] In this embodiment, the first clamping groove 301 and the second clamping groove 302 are staggered along the circumferential direction of the rotating disk 30. The first clamping groove 301 and the second clamping groove 302 are staggered along the circumferential direction of the rotating disk 30. The first clamping groove 301 and the second clamping groove 302 can be both provided in plurality and spaced apart along the circumferential direction of the rotating disk 30.

[0070] See also Figure 8 , Figure 82 is a schematic diagram of the structure of the through hole 2101 in the mounting structure 21 provided in some embodiments of the present application. In some embodiments, the cross-sectional area of ​​the through hole 2101 gradually decreases along the second direction D2. On the projection plane perpendicular to the second direction D2, the orthographic projection of the clamping member 40 is located outside the orthographic projection of the opening of the through hole 2101 on the side close to the pressing structure 221. In this way, when the clamping member 40 moves to the unlocking position, the hole wall of the through hole 2101 can abut against the clamping member 40, thereby limiting the clamping member 40 in the through hole 2101 and preventing the clamping member 40 from sliding from the through hole 2101 to the movable groove 2102.

[0071] See also Fig. 9 , Fig. 9 2 is a schematic diagram of the structure of the through hole 2101 in the mounting structure 21 provided in other embodiments of the present application. In some embodiments, on the projection plane perpendicular to the second direction D2, the orthographic projection of the clamping member 40 is located outside the orthographic projection of the opening of the through hole 2101 away from the pressing structure 221. In this way, when the clamping member 40 moves to the locking position, the hole wall of the through hole 2101 can abut against the clamping member 40, thereby limiting the clamping member 40 in the through hole 2101 to prevent the clamping member 40 from sliding from the through hole 2101 to the outside of the mounting structure 21. In some embodiments, when on the projection plane perpendicular to the second direction D2, the orthographic projection of the clamping member 40 is located outside the orthographic projection of the opening of the through hole 2101 away from the pressing structure 221, the turntable assembly 100 may not be provided with the cover 24, the pressing block 231 and the second elastic member 232, so as to simplify the structure of the turntable assembly 100.
