In other embodiments of the present application, the walking device 1000 may include Figure 1 More or fewer components as shown, or a combination of certain components, or different components, for example, the walking device 1000 may also include but is not limited to a material collection device, a sensor, and the like.

[0033] In some embodiments, the walking device 1000 also includes a driving device 200 that is transmission-connected to the locking device 300.

The locking device 300 includes a mounting structure 10, a locking structure 20, a pressing structure 30, a pushing structure 40, a first resetting member 50 and a second resetting member 60. A through hole 101 is provided on the mounting structure 10. The locking structure 20 is movably provided in the through hole 101. The pressing structure 30 can move between a first position P1 and a second position P2 relative to the mounting structure 10. The pushing structure 40 can move between a third position P3 and a fourth position P4 relative to the mounting structure 10. The first resetting member 50 is used to provide power to move the pressing structure 30 to the first position P1. The second resetting member 60 is used to provide power to move the pushing structure 40 to the third position P3. When the pressing structure 30 is located at the first position P1 and the pushing structure 40 is located at the fourth position P4, the pushing structure 40 is disengaged from the abutment with the locking structure 20, the pressing structure 30 is located at the first side of the through hole 101 and abuts against the locking structure 20, the locking structure 20 protrudes from the second side of the through hole 101, and is used to cooperate and fix with the to-be-locked member 100. When the pressing structure 30 is located at the second position P2 and the pushing structure 40 is located at the third position P3, the pushing structure 40 is located at the second side of the through hole 101 and abuts against the locking structure 20, the locking structure 20 protrudes from the first side of the through hole 101, and is used to disengage from the to-be-locked member 100.

[0037] The locking device 300 and walking device 1000 provided in the present application are based on the setting that the locking device 300 includes an installation structure 10, a locking structure 20, a pressing structure 30, a pushing structure 40, a first reset member 50 and a second reset member 60, and a through hole 101 is provided on the installation structure 10; the locking structure 20 is movably provided in the through hole 101; the pressing structure 30 can move between a first position P1 and a second position P2; the pushing structure 40 can move between a third position P3 and a fourth position P4; when the pressing structure 30 is located at the first position P1 and the pushing structure 40 is located at the fourth position P4, the pushing structure 40 is disengaged from the abutment with the locking structure 20, the pressing structure 30 is located at a first side of the through hole 101 and abuts against the locking structure 20, the locking structure 20 protrudes from the second side of the through hole 101, and is used to cooperate and fix with the member to be locked 100; when the pressing structure 30 is located at the first position P1 and the pushing structure 40 is located at the fourth position P4, the pushing structure 40 is disengaged from the abutment with the locking structure 20, the pressing structure 30 is located at a first side of the through hole 101 and abuts against the locking structure 20, the locking structure 20 protrudes from the second side of the through hole 101, and is used to cooperate and fix with the member to be locked 100; When the locking member 100 is in the second position P2 and the pushing structure 40 is in the third position P3, the pushing structure 40 is located at the second side of the through hole 101 and abuts against the locking structure 20. The locking structure 20 protrudes from the first side of the through hole 101 and is used to disengage from the piece 100 to be locked. On the one hand, the piece 100 to be locked and the mounting structure 10 can be disengaged by pressing the pressing structure 30 once, thereby realizing the rapid disassembly and assembly of the piece 100 to be locked and the mounting structure 10, and improving the assembly efficiency and convenience of the piece 100 to be locked and the mounting structure 10. On the other hand, by setting the pressing structure 30 and the pushing structure 40 to push the locking structure 20 to different sides of the through hole 101, the locking and unlocking operations of the piece 100 to be locked and the mounting structure 10 can be realized. The structure is simple and compact, and the production cost of the locking device 300 is reduced and the volume of the locking device 300 is reduced.

[0038] The locking device 300 has a locked state and an unlocked state. When the pressing structure 30 is located at the first position P1 and the pushing structure 40 is located at the fourth position P4, the locking device 300 is in the locked state. When the pressing structure 30 is located at the second position P2 and the pushing structure 40 is located at the third position P3, the locking device 300 is in the unlocked state. It should be noted that the term "locked state" refers to a state in which the member to be locked 100 cannot be removed from the locking device 300. The term "unlocked state" refers to a state in which the member to be locked 100 can be removed from the locking device 300 and the member to be locked 100 can be installed on the locking device 300 along the first direction X.

[0039] For the accuracy of description, please refer to the directions in this article. Figure 3For reference, the term "axial direction" used in the embodiments and claims herein refers to the direction parallel to the central axis A of the output shaft 220 of the drive device 200, that is, the direction parallel to the insertion direction of the locked member 100 and the locking device 300, wherein the extension direction of the X-axis is the up-down direction (where the positive direction of the X-axis is upward); the term "radial direction" refers to the direction perpendicular to the central axis A of the output shaft 220 of the drive device 200, that is, the radial direction along the cross section of the turntable 110, wherein the extension direction of the Y-axis is the left-right direction (where the positive direction of the Y-axis is left); the term "circumferential direction" refers to the direction of the central axis A surrounding the output shaft 220 of the drive device 200, that is, the circumferential direction of the turntable 110. The axial direction, radial direction and circumferential direction together constitute the three orthogonal directions of the output shaft 220 of the drive device 200. For the convenience of description, the up-down, left-right, front-back orientations in this application are relative positions and do not constitute a limitation to the implementation. The axial direction, radial direction and circumferential direction can be customized according to the specific structure of the product and the perspective of the drawings, and this application does not make specific limitations.

[0040] In some embodiments, when the pressing structure 30 is located at the first position P1 and the pushing structure 40 is located at the fourth position P4, the pushing structure 40 is used to abut against the member to be locked 100, and the second reset member 60 is in a compressed state and elastically abuts against the side of the pushing structure 40 that faces away from the member to be locked 100. Thus, on the one hand, the second reset member 60 can push the pushing structure 40 during the process of disassembling the member to be locked 100, so as to eject the member to be locked 100 from the mounting structure 10, which is convenient for disassembly; on the other hand, the second reset member 60 can realize the push structure 40 to return to the initial position, so as to realize the elastic deformation of the second reset member 60 when the member to be locked 100 is locked on the mounting structure 10 next time, and prevent foreign matter from entering the through hole 101 and jamming the locking structure 20. One end of the second reset member 60 that faces away from the pushing structure 40 can elastically abut against the mounting structure 10. For example, one end of the second reset member 60 that faces away from the pushing structure 40 can be connected to the mounting structure 10.

[0041] It can be understood that when the second reset member 60 is in a compressed state, the elastic force generated by the second reset member 60 is applied to the pushing structure 40, so that the pushing structure 40 can provide a pushing force to the member to be locked 100 that can be separated from the locking structure 20. Therefore, after the pressing structure 30 moves from the first position P1 to the second position P2, the first reset member 50 is in a compressed state, and the elastic force generated by the second reset member 60 drives the pushing structure 40 to push the member to be locked 100 out of the mounting structure 10, and the pushing structure 40 moves from the fourth position P4 to the third position P3, and the member to be locked 100 pushes the locking structure 20 and extends out of the side of the through hole 101 close to the pressing structure 30. At this time, the pressing structure 30 is located at the second position P2, and the pushing structure 40 is located at the third position P3. It can be understood that, in the process of locking the member to be locked 100 on the mounting structure 10, the member to be locked 100 is pushed by the external force to push the pushing structure 40 from the third position P3 to the fourth position P4, so that the second restoring member 60 undergoes elastic deformation, at which time, the first restoring member 50 gradually recovers its deformation, and pushes the locking structure 20 to extend out of the through hole 101 close to the side of the member to be locked 100, and locks it to the member to be locked 100. At this time, the pressing structure 30 is located at the first position P1, and the pushing structure 40 is located at the fourth position P4.

[0042] Exemplarily, in this embodiment, the first reset member 50 and the second reset member 60 are each configured as a spring. In some embodiments, the first reset member 50 and the second reset member 60 can also be configured as a spring, an elastomer or other elastic structure, which is not specifically limited in the embodiment of the present application.

[0043] In some embodiments, when the pressing structure 30 is located at the second position P2 and the pushing structure 40 is located at the third position P3, the pushing structure 40 covers the through hole 101. Thus, on the one hand, the pushing structure 40 can block foreign matter from entering the through hole 101, preventing the foreign matter from getting stuck in the locking structure 20; on the other hand, it ensures that the pushing structure 40 can push the locking structure 20 into the interior of the mounting structure 10, so that the locking structure 20 is clamped between the pressing structure 30 and the pushing structure 40.

[0044] When the pressing structure 30 is located at the second position P2 and the pushing structure 40 is located at the third position P3, the pushing structure 40 may cover part of the through hole 101 or cover the entire through hole 101. Of course, in some embodiments, when the pressing structure 30 is located at the second position P2 and the pushing structure 40 is located at the third position P3, the pushing structure 40 may be located outside the area corresponding to the through hole 101, which is not specifically limited in the embodiments of the present application.

[0045] In some embodiments, when the pressing structure 30 is located at the second position P2 and the pushing structure 40 is located at the third position P3, the end surface of the pushing structure 40 facing away from the second reset member 60 is located below the lower edge of the through hole 101; or, the end surface of the pushing structure 40 facing away from the second reset member 60 is flush with the lower edge of the through hole 101, so that the pushing structure 40 can block foreign objects from entering the through hole 101 and prevent the foreign objects from getting stuck in the locking structure 20.

[0046] Exemplarily, in this embodiment, the mounting structure 10 includes a mounting plate 11 and a surrounding plate 12. The mounting plate 11 is connected to the surrounding plate 12 to form a receiving cavity 102. The surrounding plate 12 is provided with a through hole 101 connected to the receiving cavity 102. The pressing structure 30 is disposed against the inner wall of the surrounding plate 12, and the pushing structure 40 is disposed against the outer wall of the surrounding plate 12. The maximum length of the locking structure 20 in the radial direction of the surrounding plate 12 is greater than the extension length of the through hole 101 in the radial direction of the surrounding plate 12. Therefore, on the one hand, the pressing structure 30 and the pushing structure 40 can push the locking structure 20 out from the corresponding side of the through hole 101 during the movement relative to the mounting structure 10, thereby realizing the locking and unlocking operations of the locking member 100, which has a simple structure and improves the assembly efficiency and convenience; on the other hand, the pressing structure 30 is arranged in contact with the inner wall of the enclosure 12, and the pushing structure 40 is arranged in contact with the outer wall of the enclosure 12, so that the enclosure 12 can guide the movement of the pressing structure 30 and the pushing structure 40, thereby improving the reliability and stability of the movement of the pressing structure 30 and the pushing structure 40 relative to the mounting structure 10.

[0047] It should be noted that the term "abutting" means that one element is closely adjacent to another element, that is, one element abuts against another element; or, one element is close to another element, that is, there is a gap between the two elements, and the gap is within a preset range and is relatively small. For example, the pushing structure 40 and the outer side wall of the enclosure 12 are abutted, which means that the inner side wall of the pushing structure 40 abuts against the outer side wall of the enclosure 12, or the inner side wall of the pushing structure 40 and the outer side wall of the enclosure 12 are close to each other and there is a gap.

Exemplarily, in the present embodiment, the mounting plate 11 is fixedly connected to the output shaft 220 of the driving device 200. Specifically, a mounting boss 1101 is provided on the side of the mounting plate 11 facing away from the enclosure 12. The output shaft 220 of the driving device 200 is fixedly connected to the mounting boss 1101, so as to facilitate the alignment assembly of the driving device 200 and the locking device 300, and the mounting boss 1101 increases the connection length between the output shaft 220 and the mounting boss 1101, reduces the swing of the central axis A of the output shaft 220 relative to the mounting structure 10, and improves the stability and reliability of the connection between the output shaft 220 and the mounting structure 10. The output shaft 220 and the mounting boss 1101 can be, but not limited to, fixedly connected by a locking structure. The mounting boss 1101 is provided with an anti-rotation hole 1102, and the output shaft 220 cooperates with the anti-rotation hole 1102. The anti-rotation hole 1102 is connected to the accommodating cavity 102, so that the locking structure can pass from the accommodating cavity 102 into the anti-rotation hole 1102 and be locked on the output shaft 220, which improves the aesthetics and prevents the locking structure from falling off. The anti-rotation hole 1102 can be configured as but not limited to a waist-shaped hole, a triangular hole, a trapezoidal hole, a polygonal hole, etc. The enclosure 12 is configured as a hollow cylindrical structure. The enclosure 12 is connected to the edges of the mounting plate 11. The pressing structure 30 is also configured as a cylindrical structure, which is slidably accommodated in the accommodating cavity 102. In some embodiments, the mounting boss 1101 can be omitted, that is, the output shaft 220 is fixedly connected to the mounting plate 11 of the mounting boss 1101.

[0049] In some embodiments, at least one of the mounting structure 10 and / or the pressing structure 30 is provided with a positioning structure 301 for positioning the first reset member 50. Thus, the setting of the positioning structure 301 can provide accurate positioning for the first reset member 50, prevent the first reset member 50 from shifting or falling off during use, ensure that the first reset member 50 is always in the correct position, and can limit the excessive deformation of the first reset member 50, thereby improving the stability of the overall structure. The positioning structure 301 can be configured as a positioning groove or a positioning protrusion. Exemplarily, in this embodiment, the pressing structure 30 is provided with a positioning groove, and the mounting structure 10 is provided with a positioning protrusion. One end of the first reset member 50 is sleeved on the outside of the positioning protrusion, and the other end of the first reset member 50 is accommodated in the positioning groove. Of course, in some other embodiments, the positioning structure 301 can be omitted, that is, the first reset member 50 elastically abuts between the mounting structure 10 and the pressing structure 30.

[0050] Exemplarily, in the present embodiment, the pushing structure 40 can be configured as an annular structure and slidably sleeved on the outer side of the enclosure 12. As a result, the load applied by the pushing structure 40 to the second reset member 60 can be evenly distributed, avoiding local stress concentration, extending the service life of the second reset member 60, and improving the stability and reliability of the elastic expansion and contraction of the second reset member 60. Of course, in some embodiments, the pushing structure 40 can also be configured as an arc structure. The number of arc structures is the same as that of the locking structure 20, and they are arranged one by one. The pushing structure 40 and the second reset member 60 are arranged independently of each other and abut against each other. The pushing structure 40 and the second reset member 60 can also be fixedly connected.

[0051] The first reset member 50 and the pressing structure 30 are movably accommodated in the accommodating cavity 102, and the first reset member 50 is arranged between the mounting plate 11 and the pressing structure 30. Therefore, the pressing structure 30 and the first reset member 50 can be movably arranged in the accommodating cavity 102 provided in the mounting structure 10. On the one hand, the problem of the turntable 110 being unlocked from the mounting structure 10 due to the user's accidental touching of the pressing structure 30 is avoided, and the use safety of the locking device 300 is improved; on the other hand, the load applied by the pressing structure 30 to the first reset member 50 can be evenly distributed, avoiding local stress concentration, extending the service life of the first reset member 50, and improving the stability and reliability of the elastic expansion of the first reset member 50. In some embodiments, the inner side wall of the enclosure 12 is provided with a limiting structure 13, and the limiting structure 13 is used to limit the movement stroke of the pressing structure 30. Therefore, on the one hand, the pressing structure 30 is prevented from exceeding the set range of movement and being separated from the alignment assembly with the mounting structure 10, and the repeatability and reliability of the use of the pressing structure 30 are improved; on the other hand, the positioning accuracy of the pressing structure 30 relative to the mounting structure 10 is improved.

[0052] In some embodiments, the locking device 300 further includes a buffer structure 14. The pressing structure 30 abuts against the limit structure 13 through the buffer structure 14. As a result, the buffer structure 14 can absorb the impact or vibration generated by the relative movement of the pressing structure 30 to the mounting structure 10, thereby extending the service life of the locking device 300; on the other hand, the provision of the buffer structure 14 facilitates the installation of the first reset member 50, the pressing structure 30 and the buffer structure 14 in the accommodating cavity 102 of the mounting structure 10. The buffer structure 14 can be configured as, but not limited to, a rubber ring, a damper, a foam structure or a carbon fiber structure, etc. Specifically, the mounting structure 10 is provided with a limit step 16 in the accommodating cavity 102, and the buffer structure 14 is sandwiched between the limit step 16 and the limit structure 13. Of course, in some embodiments, the limit step 16 can be omitted, that is, the buffer structure 14 can also be directly overlapped on the limit structure 13, and used to stop the pressing structure 30, thereby preventing the pressing structure 30 from being separated from the alignment assembly with the mounting structure 10.

[0053] For example, in this embodiment, when the limiting structure 13 abuts against the pressing structure 30, the end surface of the pressing structure 30 facing away from the first reset member 50 is retracted relative to the end surface of the mounting structure 10 facing the member to be locked 100 and is arranged on the side of the first reset member 50. In some embodiments, when the limiting structure 13 abuts against the pressing structure 30, the end surface of the pressing structure 30 facing away from the first reset member 50 is arranged coplanar with the end surface of the mounting structure 10 facing the member to be locked 100. Thus, the pressing structure 30 is prevented from protruding relative to the member to be locked 100, and the risk of the member to be locked 100 being accidentally removed by the pressing structure 30 due to the stones on the ground being pushed against the pressing structure 30 can be reduced. In some other embodiments, when the limiting structure 13 abuts against the pressing structure 30, the end surface of the pressing structure 30 facing away from the first reset member 50 is convexly set to a preset length relative to the end surface of the mounting structure 10 facing the member to be locked 100 and is arranged on the side away from the first reset member 50. The protruding length of the pressing structure 30 relative to the mounting structure 10 is within a preset length range, thereby reducing the risk of stones on the ground hitting the pressing structure 30 and accidentally removing the locking member 100.

[0054] In some embodiments, the locking device 300 further includes a guide structure 15, which is disposed on the outer side wall of the enclosure 12 and is used to limit the movement stroke of the push structure 40. Thus, on the one hand, the provision of the guide structure 15 can also prevent the push structure 40 from exceeding the set movement range and being out of alignment with the mounting structure 10, thereby improving the repeatability and reliability of the use of the push structure 40; on the other hand, the provision of the guide structure 15 can also improve the positioning accuracy of the push structure 40 relative to the mounting structure 10, and enable the push structure 40 to cover the through hole 101 and abut against the to-be-locked member 100 when the locking device 300 is in the locked state.

[0055] In some embodiments, the locking device 300 further includes a protective cover 70. The protective cover 70 is fixedly connected to the mounting structure 10, and forms a protective cavity 701 and an insertion port 702 connected to the protective cavity 701. The second reset member 60 and the pushing structure 40 can be movably arranged in the protective cavity 701, and the insertion port 702 is used for inserting the member 100 to be locked. Thus, on the one hand, it is prevented that the user operates the second reset member 60 and the pushing structure 40, causing the locking device 300 to malfunction; on the other hand, the protective cover 70 and the mounting structure 10 can guide the movement of the pushing structure 40, thereby improving the smoothness and reliability of the movement of the pushing structure 40. The guide structure 15 can also be arranged on the inner side wall of the protective cover 70; or, part of the guide structure 15 can be arranged on the inner side wall of the protective cover 70, and the remaining part of the guide structure 15 can be arranged on the inner side wall of the protective cover 70.

[0056] In some other embodiments, the locking device 300 may also omit the guide structure 15. Specifically, the pushing structure 40 is connected to the mounting structure 10 or the protective cover 70 through the second reset member 60. One end of the second reset member 60 is fixedly connected to the pushing structure 40, and the other end of the second reset member 60 is fixedly connected to the mounting structure 10 or the protective cover 70, so that the pushing structure 40 is suspended on the second reset member 60. When the pushing structure 40 moves from the fourth position P4 to the third position P3, the pushing structure 40 abuts against the locking structure 20, and pushes the locking structure 20 out of the through hole 101 close to the side of the pressing structure 30.

[0057] Exemplarily, in the present embodiment, the protective cover 70 is configured as a semi-open cylindrical structure. The protective cover 70 includes a connecting end 71 and a free end 72 that are arranged opposite to each other. The connecting end 71 is located at one end of the protective cover 70 that is away from the insertion port 702 and is fixedly connected to the mounting structure 10. The free end 72 is connected to the edges around the connecting end 71 and forms an insertion port 702 with the mounting structure 10 on the side away from the free end 72. The mounting boss 1101 of the mounting structure 10 is passed through the connecting end 71 and is fixedly connected to the output shaft 220. In some embodiments, the mounting boss 1101 can be omitted, that is, the output shaft 220 is passed through the protective cover 70 and is fixedly connected to the mounting boss 1101.

[0058] In some embodiments, the guide structure 15 is extended along the direction in which the pushing structure 40 moves relative to the mounting structure 10, and is used to cooperate with the guide groove 1003 provided on the member to be locked 100. Therefore, on the one hand, the cooperation between the guide structure 15 and the guide groove 1003 can guide the member to be locked 100, thereby improving the reliability and stability of the member to be locked 100 relative to the mounting structure; on the other hand, the cooperation between the guide structure 15 and the guide groove 1003 can prevent the rotating disk 110 from rotating relative to the mounting structure 10, thereby preventing the rotating rotating disk 110 from causing harm to the user, and improving the safety of disassembling the rotating disk 110.

[0059] The guide groove 1003 has a tapered opening 1004 at the end of one side close to the mounting structure 10. The tapered opening 1004 can help the guide structure 15 automatically align to the center position and reduce deviation. The tapered opening 1004 can make the guide structure 15 gradually enter from wide to narrow, reduce initial resistance, and make insertion smoother. The setting of the tapered opening 1004 can also simplify the assembly process, without the need for precise alignment, and improve the operating efficiency. The tapered opening 1004 can also prevent the guide structure 15 from directly colliding with the edge of the groove wall of the guide groove 1003, reducing damage to components and equipment.

[0060] Please also read Figures 2 to 7 , Figure 7 yes Figure 1The enlarged view of the local structure of the turntable 110 of the walking device 1000 in FIG. The turntable 110 includes a turntable body 111 and a connecting sleeve 112. The connecting sleeve 112 is arranged in the middle of the top of the turntable body 111. The turntable body 111 is provided with a through hole 1005 connected to the inner cavity of the connecting sleeve 112. The mounting structure 10 can be sequentially penetrated into the inner cavity of the connecting sleeve 112 and the through hole 1005. The mounting structure 10 is provided with a receiving cavity 102 and a through hole 103 connected to the receiving cavity 102. The pressing structure 30 is located in the receiving cavity 102 and is exposed to the side of the turntable body 111 away from the connecting sleeve 112 through the through hole 103 and the through hole 1005. As a result, it is convenient for users to operate the pressing structure 30, which improves the user experience. At the same time, it is avoided that the user accidentally touches the pressing structure 30 to cause the turntable 110 to be unlocked from the mounting structure 10, thereby improving the safety of the locking device 300.

[0061] The inner side wall of the connecting sleeve 112 is provided with a locking groove 1001 that matches with the locking structure 20. The inner side wall of the connecting sleeve 112 is also provided with a guide groove 1003 that matches with the guide structure 15. In this embodiment, the locking structure 20 and the guide structure 15 are each provided in plurality, and the plurality of locking structures 20 and the plurality of guide structures 15 are each arranged at intervals along the circumferential direction of the enclosure 12, and the locking structure 20 and the guide structure 15 are arranged at intervals on the projection surface perpendicular to the axial direction of the enclosure 12. Thus, interference between the to-be-locked member 100 and the mounting structure 10 during the plug-in connection process is avoided; on the other hand, the locking structure 20 and the guide structure 15 are arranged at intervals along the circumferential direction of the enclosure 12, so that the structure is compact, and the locking structure 20 and the locking groove 1001 are ensured to be accurately aligned, thereby improving the assembly yield and assembly efficiency.

[0062] For example, in this embodiment, the inner side wall of the connecting sleeve 112 is provided with a locking groove 1001. When the push structure abuts against the locking structure 20, part of the structure of the locking structure 20 is disengaged from the locking groove 1001; when the pressing structure 30 abuts against the locking structure 20, part of the structure of the locking structure 20 is fixedly matched with the locking groove 1001. Thus, based on the locking groove 1001 being provided on the side wall of the connecting sleeve 112, the locking groove 1001 does not simultaneously penetrate the inner side wall and the outer side wall of the connecting sleeve 112, so that the connecting sleeve 112 has good structural strength; on the other hand, the provision of the locking groove 1001 can limit the depth of the locking structure 20 accommodated in the locking groove 1001, and the locking groove 1001 can also intercept obstacles outside the connecting sleeve 112 from entering the locking groove 1001, thereby reducing the risk of the locking structure 20 being stuck.

[0063] Of course, in some embodiments, the connecting sleeve 112 is provided with a locking hole for cooperating with the locking structure 20. The locking hole penetrates the inner wall and the outer wall of the connecting sleeve 112, so as to facilitate the processing and forming of the locking hole.

[0064] The number of locking grooves 1001 is set in one-to-one correspondence with the number of locking structures 20. For example, four locking grooves 1001 and four locking structures 20 are set, and the four locking grooves 1001 are arranged at intervals along the circumferential direction of the connecting sleeve 112, and are matched and fixed with the four locking structures 20 in one-to-one correspondence. It should be noted that the number of locking grooves 1001 and the number of locking structures 20 are only used for illustration, and the embodiments of the present application do not make specific limitations. For example, the number of locking grooves 1001 can also be less than or more than the number of locking structures 20, the number of locking grooves 1001 can also be set to one, two, three or more than four, and the number of locking structures 20 can also be set to one, two, three or more than four.

[0065] The two groove side walls of the locking groove 1001 in the first direction X are respectively extended outward relative to the groove bottom wall of the locking groove 1001. In other words, the two groove side walls of the locking groove 1001 in the first direction X are respectively arranged at an obtuse angle with the groove bottom wall of the locking groove 1001. Thus, the two groove side walls of the locking groove 1001 in the first direction X can guide the locking structure 20 to enter or leave the locking groove 1001, thereby improving the assembly efficiency of the rotating disk 110 and the locking device 300.

[0066] The locking structure 20 is fixed with the locking groove 1001, and the two groove side walls of the locking groove 1001 in the second direction Y are respectively arranged perpendicularly relative to the groove bottom wall of the locking groove 1001, so that the cooperation between the locking structure 20 and the locking groove 1001 can ensure that the turntable 110 will not separate from the mounting structure 10 along the axial direction of the turntable 110, and at the same time prevent the turntable 110 from rotating relative to the mounting structure 10, thereby avoiding the rotating turntable 110 from causing harm to the user, thereby improving the safety of disassembly of the turntable 110.

[0067] In some embodiments, in the axial direction of the through hole 101, the area of ​​the cross section of the through hole 101 gradually decreases from the arrangement direction of the pushing structure 40 to the pressing structure 30, and the orthographic projection of the locking structure 20 in the axial direction of the through hole 101 is located outside the orthographic projection of the opening of the through hole 101 close to the pressing structure 30 in the axial direction of the through hole 101; and / or, when the pressing structure 30 is located at the second position P2 and the pushing structure 40 is located at the third position P3, the locking structure 20 is sandwiched between the pressing structure 30 and the pushing structure 40. Thus, the locking structure 20 is prevented from falling into the interior of the mounting structure 10 from the through hole 101, the reliability of the connection between the locking structure 20 and the mounting structure 10 is improved, and at the same time, it is ensured that the locking structure 20 can protrude from the interior of the mounting structure 10 under the push of the pushing structure 40, thereby realizing the unlocking between the to-be-locked member 100 and the mounting structure 10.

[0068] Of course, in some other embodiments, a limiting boss may be further provided in the through hole 101 of the mounting structure 10, and the limiting boss is used to limit the movable range of the locking structure 20 in the through hole 101, thereby preventing the locking structure 20 from slipping out of the through hole 101, and improving the reliability of the connection between the locking structure 20 and the mounting structure 10.

[0069] In some embodiments, the locking member 100 is provided with a locking groove 1001 that cooperates and fixes with the locking structure 20. At least one of the side wall of the pushing structure 40 facing the locking structure 20, the side wall of the pressing structure 30 facing the locking structure 20, and the groove side wall of the locking groove 1001 is provided with a guiding inclined surface 1002, and the guiding inclined surface 1002 is used to guide the locking structure 20 to move in the through hole 101. As a result, it is convenient for these structures to push the locking structure 20 to move in the through hole 101 when moving, to prevent the locking structure 20 from getting stuck, and to improve the smoothness and convenience of assembly. Specifically, the guiding inclined surface 1002 is used to abut against the locking structure 20, and is set at an angle with the rotation axis of the turntable 110. Among them, the guiding inclined surface can be configured as an inclined surface or a plane.

[0070] The locking structure 20 is configured as at least one of a spherical structure, a cylindrical structure, a hemispherical structure, a semi-cylindrical structure, or a combination of at least two of them, which is not specifically limited in the embodiments of the present application. For example, in the present embodiment, the structure to be locked 20 is configured as a spherical structure, which has a simple structure, is easy to process and manufacture, and avoids the problem of the locking structure 20 getting stuck, thereby improving the reliability and stability of the locking structure 20 moving in the through hole 101.

[0071] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
