However, the above-mentioned locking block and the rotatable structure are too complicated to achieve locking.

DETAILED DESCRIPTION

[0061] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0062] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. In addition, the term "and / or" herein is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects, rather than to describe a specific order of objects.

[0063] At present, the locking of the rotatable structure is usually achieved by using a locking block. For example, when the rotatable structure is in a rotating state, the locking block can be driven by an external driving force to move so that the locking block can contact the dynamic rotatable structure, thereby achieving the locking of the rotatable structure. For example, the locking block can be set on a lever structure at the edge of the rotatable structure.

[0064] Specifically, when the rotatable structure rotates, an external driving force can be applied to the side of the lever structure away from the locking block so that the locking block can move up and down, and when the slot of the rotatable structure rotates to the corresponding position of the locking block, the external driving force is released so that the locking block and the slot are engaged, thereby achieving the locking of the rotatable structure. Secondly, when the rotatable structure is unlocked, it is necessary to apply an external driving force to the lever structure again to move the locking block upward, so that the locking block is separated from the slot of the rotatable structure, and the rotatable structure is unlocked.

[0065] However, the locking method of the locking block and the rotatable structure is too complicated. Therefore, the locking structure for locking or unlocking the rotatable structure in the prior art still has the problem of high complexity.

[0066] Based on this, an embodiment of the present application provides a locking structure 10, which can lock and unlock the locking structure 10 by moving the first end of the supporting assembly 13 in the guide groove 112 when the rotating assembly 12 rotates, thereby reducing the complexity of the locking structure.

[0067] In one embodiment of the present application, Figure 1 1 is a schematic diagram of a structure of the locking structure 10 provided in the embodiment of the present application. Figure 1 As shown, the locking structure 10 includes: at least one guide block 11, a rotating component 12 and a supporting component 13; a snap-fit ​​component 111 is provided at one end of the guide block 11 close to the rotating component 12, and the rotating component 12 matches the snap-fit ​​component 111; a guide groove 112 is also provided on the guide block 11, and a first end of the supporting component 13 is movably arranged in the guide groove 112, and the other end of the supporting component 13 is a fixed end.

[0068] Specifically, the rotating component 12 is used to contact the snap component 111 when rotating, so as to drive the guide block 11 to move through the snap component 111, and drive the first end of the support component 13 to move to the unlocking position of the guide groove 112 through the guide block 11, and the locking structure 10 is in an unlocked state when the first end of the support component 13 moves to the unlocking position; it is also used to engage with the snap component 111 when rotating to the snapping position of the snap component 111, and drive the first end of the support component 13 to move from the unlocking position of the guide groove 112 to the locking position of the guide groove 112 through the guide block 11, and the locking structure 10 is in a locked state when the first end of the support component 13 moves to the locking position.

[0069] In an embodiment of the present application, a snap-fit ​​component 111 may be provided on a side of the guide block 11 close to the rotating component 12 so as to engage with the snap-fit ​​component 111 when the rotating component 12 rotates to the corresponding position of the snap-fit ​​component 111, wherein the corresponding position of the snap-fit ​​component 111 may be the snap-fit ​​position of the snap-fit ​​component 111.

[0070] Exemplarily, the structure of the rotating assembly 12 can match the structure of the buckle component 111. Specifically, the rotating assembly 12 and the buckle component 111 can be respectively provided with concave-convex structures, so that the rotating assembly 12 and the buckle component 111 are buckled through the concave-convex structures when they are in relative positions.

[0071] For example, Figure 2 1 is a schematic diagram of the structure of the rotating assembly 12 and the buckle component 111 provided in the embodiment of the present application. Figure 2 As shown in (a), the rotating assembly 12 is provided with a convex structure, and the buckle component 111 is provided with a concave structure; Figure 2As shown in (b), when the rotating assembly 12 rotates to a relative position to the buckle component 111, the rotating assembly 12 and the buckle component 111 are buckled.

[0072] In a possible implementation, the guide block 11 is further provided with a guide groove 112. Exemplarily, the guide groove 112 may be provided on a side surface of the guide block 11 that is parallel to the moving direction of the guide block 11. For example, the guide block 11 may be a rectangular block structure.

[0073] In a possible implementation, the locking structure 10 further includes a support assembly 13. Exemplarily, the size of the support assembly 13 may match the size of the guide slot 112, so that the first end of the support assembly 13 may be movably disposed in the guide slot 112.

[0074] Specifically, the width of the first end of the support component 13 may be the same as the width of the guide slot 112. For example, the support component 13 may be a pull rod with extensions at both ends, wherein the width of the pull rod is the same as the width of the guide slot 112; and the length of the extensions at both ends of the pull rod may be the same as the depth of the guide slot 112.

[0075] It should be noted that, in order to maintain the connection state between the support assembly 13 and the guide groove 112, the opening of the guide groove 112 can be set as a limit opening. For example, the width of the opening of the guide groove 112 can be set to be smaller than the width of the guide groove 112 to prevent the support assembly 13 from being separated from the guide groove 112 through the opening of the guide groove 112.

[0076] In a possible implementation, since the second end of the support assembly 13 is a fixed end, when the guide block 11 moves, the first end of the support assembly 13 can move in the guide groove 112 along with the movement of the guide block 11 .

[0077] For example, the guide block 11 can be driven to move by the rotating assembly 12. Specifically, when the rotating assembly 12 is in a rotating state and contacts the buckle portion 111, the guide block 11 can be driven to move by its own rotation; and when the rotating assembly 12 rotates to the buckle position of the buckle portion 111, it can be engaged with the buckle portion 111. The rotating assembly 12 can rotate around its own midpoint or around the rotation axis.

[0078] Exemplarily, when the guide block 11 moves driven by the rotating component 12, the first end of the supporting component 13 can move to the unlocking position in the guiding groove 112, and the locking structure 10 is in the unlocking state; and when the rotating component 12 is engaged with the snap-fitting part 111, the first end of the supporting component 13 can move to the locking position in the guiding groove 112, and the locking structure 10 is in the locking state.

[0079] It should be noted that the locking position may be a limit point in the guide groove 112. Specifically, when the first end of the support assembly 13 moves to the limit point, when the rotating assembly 12 does not rotate, the first end of the support assembly 13 is limited to the limit point, so that the locking state of the locking structure 10 can be further ensured by the support assembly 13.

[0080] Compared with the prior art in which the locking block is driven by an external driving force to achieve locking or unlocking of the rotatable structure in a rotating state, the locking structure 10 provided in the embodiment of the present application can drive the guide block 11 to move by contacting the snap component 111 (disposed on the guide block 11) when the rotating component 12 rotates, so as to drive the first end of the support component 13 to move along the guide groove 112 of the guide block 11 as the guide block 11 moves, and realizes unlocking and locking of the locking structure 10 when the support component 13 moves to the unlocking position and the unlocking position respectively, thereby reducing the complexity of the locking structure.

[0081] In another embodiment of the present application, other structural distributions of the locking structure 10 are also introduced. Exemplarily, the locking structure 10 further includes an elastic component 14 ; one end of the elastic component 14 is a fixed end, and the other end of the elastic component 14 is connected to the guide block 11 .

[0082] Specifically, when the rotating component 12 rotates along the first direction, the rotating component 12 contacts the snap component 111, and drives the guide block 11 to move away from the elastic component 14 through the snap component 111 to stretch the elastic component 14; when the rotating component 12 rotates along the second direction, the rotating component 12 contacts the snap component 111, and drives the guide block 11 to move toward the elastic component 14 through the snap component 111, and the elastic component 14 rebounds.

[0083] In a possible implementation, the locking structure 10 may further include an elastic component 14. For example, the elastic component 14 may be a tension spring.

[0084] For example, Figure 3 is another structural schematic diagram of the locking structure 10 provided in an embodiment of the present application, such as Figure 3 As shown, the locking structure 10 further includes an elastic component 14 , one end of the elastic component 14 is a fixed end, and the other end of the elastic component 14 is connected to the guide block 11 .

[0085] Specifically, a region matching the port of the elastic component 14 may be provided at one end of the guide block 11 close to the elastic component 14, so as to realize the connection between the tension spring and the guide block 11. For example, when the elastic component 14 is a tension spring, both ends of the tension spring may be pull rings, and in this case, a groove matching the size of the pull ring may be provided at one end of the guide block 11 close to the tension spring, so that the pull ring is sleeved in the groove, thereby realizing the connection between the tension spring and the guide block 11.

[0086] In a possible implementation, based on the connection state between the elastic component 14 and the guide block 11 , the stretching state of the elastic component 14 can be changed by moving the guide block 11 .

[0087] Illustratively, when the rotating component 12 rotates along a first direction, the rotating component 12 can contact the snap component 111, and when the rotating component 12 is in a rotating state, the snap component 11 drives the guide block 11 to move away from the elastic component 14 through the snap component 111, thereby stretching the elastic component 14; wherein, the first direction can be a direction close to the guide block 11.

[0088] Specifically, when the rotating assembly 12 rotates in a direction approaching the guide block 11 , it can press against the buckle component 111 , so as to drive the guide block to move in a direction away from the elastic assembly 14 through the buckle component 111 .

[0089] Illustratively, when the rotating component 12 rotates along the second direction and the rotating component 12 and the snap component 111 are still in contact, the rotating component 12 can drive the guide block 11 to move toward the direction close to the elastic component 14, and the elastic component 14 rebounds; wherein the second direction can be the direction away from the guide block 11.

[0090] Specifically, when the rotating assembly 12 rotates away from the guide block 11, the pressure on the snap component 111 disappears, but the rotating assembly 12 and the snap component 111 still maintain contact. At this time, the rotating assembly 12 drives the guide block 11 to move toward the elastic assembly 14 through the snap component 111.

[0091] In another embodiment of the present application, the association between the guide block 11 and the rotating assembly 12 during movement is also introduced. Exemplarily, when the rotating assembly 12 rotates in the second direction and the rotating assembly 12 is disengaged from the buckle component 111, the guide block 11 moves toward the direction close to the elastic assembly 14 under the action of the elastic assembly 14; wherein the second direction is opposite to the first direction.

[0092] In the embodiment of the present application, when the rotating assembly 12 rotates in the second direction to be disengaged from the buckle component 111 , the elastic force released by the elastic assembly 14 can drive the guide block 11 to move in a direction close to the elastic assembly 14 .

[0093] In another embodiment of the present application, a specific distribution mode of the guide groove 112 is also introduced. Exemplarily, the extension direction of the guide groove 112 matches the moving direction of the guide block 11 , and the locking position is located in the limiting area of ​​the guide groove 112 .

[0094] In the embodiment of the present application, the extension direction of the guide groove 112 can be set to a direction that matches the moving direction of the guide block 11, so that when the guide block 11 moves, the first end of the support assembly 13 can move along the guide groove 112 in the opposite direction of the moving direction of the guide block 11.

[0095] In a possible implementation, the extending direction of the guide groove 112 may match the moving direction of the guide block 11 .

[0096] Exemplarily, when the guide block 11 moves toward or away from the elastic component 14, the first end of the support component 13 moves toward or away from the elastic component 14, and the guide groove 112 extends in this direction.

[0097] In a possible implementation, the locking position may be located in a limiting region of the guide slot 112 to limit the position of the first end of the support assembly 13. The locking position may be located at the lowest point of the limiting region.

[0098] Exemplarily, the limiting area of ​​the guide slot 112 may be connected to the extension direction of the guide slot 112. Specifically, when the locking structure 10 switches from the locked state to the unlocked state, the first end of the support assembly 13 may move from the limiting area of ​​the guide slot 112 to the extension area.

[0099] For example, Figure 4 is a structural schematic diagram of the guide block 11 provided in the embodiment of the present application, such as Figure 4 As shown, the guide slot 112 includes a limiting area 401 and an extension area 402. Specifically, the moving direction of the guide block 11 is the vertical direction, and the direction of the extension area of ​​the guide slot 112 is also the vertical direction, and the two ends of the limiting area 401 are respectively connected to the two ends of the extension area 402. At this time, the lowest point position of the extension area 402 is the locking position.

[0100] In another embodiment of the present application, a specific structural distribution of the guide groove 112 is also introduced. Exemplarily, the guide groove 112 includes a first sub-groove 1121 and a second sub-groove 1122 arranged along the moving direction of the guide block 11 .

[0101] In the embodiment of the present application, the guide groove 112 can be formed by symmetrically setting the first sub-groove 1121 and the second sub-groove 1122 so that the first end of the support assembly 13 can respectively realize the unlocking and locking of the locking structure 10 along the sub-grooves on both sides.

[0102] For example, Figure 4 As shown, the extension area includes a first sub-groove 1121 and a second sub-groove 1122 which are symmetrically arranged along the moving direction (vertical direction) of the guide block 11 .

[0103] It should be noted that as long as the first sub-groove 1121 and the second sub-groove 1122 can be expressed as a structure in which the starting position, the end position and the middle position are arranged in sequence in the moving direction of the guide block 11 (that is, one end of the support assembly 13 can be clamped in the middle position of the sub-groove), they can constitute the above-mentioned guide groove 112, and no specific restrictions are made here.

[0104] In another embodiment of the present application, other structural distributions of the locking structure 10 are also introduced. Exemplarily, the locking structure 10 further includes a pressing plate 15, the rotating assembly 12 and the pressing plate 15 are stacked, and the rotating assembly 12 rotates on the pressing plate 15; wherein the thickness of the pressing plate 15 at one end close to the elastic assembly 14 is greater than the thickness of the pressing plate 15 at one end away from the elastic assembly 14.

[0105] In the embodiment of the present application, a pressing plate 15 may be provided below the rotating assembly 12 so that the rotating assembly 12 can rotate on the pressing plate 15. For example, the pressing plate 15 may contact the buckle portion 111.

[0106] In another embodiment of the present application, the specific structural distribution and specific implementation of the buckle component 111 are also introduced. Exemplarily, the buckle component 111 specifically includes a buckle part 1111 and a locking part 1112, and the buckle part 1111 is connected to the locking part 1112; wherein the buckle part 1111 contacts the side of the pressure plate 15 close to the guide block 11 and matches the rotating assembly 12; the pressure plate 15 and the locking part 1112 are stacked.

[0107] Specifically, when the rotating component 12 rotates to the locking position, the rotating component 12 and the locking part 1111 are locked with each other and when the rotating component 12 rotates in the second direction, the locking part 1112 moves along the pressure plate 15 in the direction close to the elastic component 14; when the locking part 1112 moves along the pressure plate 15 to the preset position, the locking part 1112 drives the locking part 1111 to deform, so that the locking part 1111 is disengaged from the rotating component 12.

[0108] In one possible implementation, Figure 5 1 is a schematic diagram of the structure of the buckle component 111 provided in the embodiment of the present application. Figure 5 As shown, the buckle component 111 specifically includes a buckling part 1111 and a locking part 1112. The buckling part 1111 is connected to the locking part 1112; the buckling part 1111 matches the rotating component 12.

[0109] For example, Figure 6 1 is a schematic diagram of an exploded structure of a pressure plate 15 and a guide block 11 provided in an embodiment of the present application from one perspective; Figure 6 As shown, the locking part 1111 is in contact with a side of the pressing plate 15 close to the guide block 11 . Figure 7 is a schematic diagram of the exploded structure of the pressing plate 15 and the guide block 11 provided in the embodiment of the present application from another perspective; Figure 6 It can be concluded that the pressing plate 15 and the locking part 1112 are stacked.

[0110] Specifically, when the rotating component 12 rotates in the first direction, the guide block 11 can move in the direction away from the elastic component 14, and the locking part 1112 also moves along the pressure plate 15 in the direction away from the elastic component 14; and when the rotating component 12 rotates to the locking position of the locking part 111, the rotating component 12 and the locking part 1111 are locked with each other, and the bottom end of the guide block 11 and the pressure plate 15 can be on the same horizontal line.

[0111] When the rotating assembly 12 rotates in the second direction, the guide block 11 can move toward the direction close to the elastic assembly 14, and the locking part 1112 also moves toward the direction close to the elastic assembly 14 along the pressing plate 15; and when the locking part 1112 moves to the preset position along the pressing plate 15, the locking part 1112 can drive the fastening part 1111 to deform, so that the fastening part 1111 is separated from the rotating assembly 12. The preset position can be an end of the pressing plate 15 close to the elastic assembly 14.

[0112] It should be noted that, in order to facilitate the movement of the locking part 1112 along the pressure plate 15, the locking part 1112 can be set as a cylinder.

[0113] For example, Figure 8 1 is a schematic diagram of the exploded structure of the pressing plate 15 and the guide block 11 provided in the embodiment of the present application from another perspective; Figure 8 As shown, when the locking part 1112 moves along the pressure plate 15 to the end of the pressure plate 15 close to the elastic component 14, since the thickness of the end of the pressure plate 15 close to the elastic component 14 is larger, the locking part 1112 drives the locking part 1111 to deform, thereby causing the locking part 1111 to disengage from the rotating component 12.

[0114] In another embodiment of the present application, a specific implementation method of locking and disengaging the rotating assembly 12 is also introduced. Exemplarily, the unlocking position includes a first unlocking position and a second unlocking position.

[0115] Specifically, when the rotating component 12 rotates to the corresponding position of the snap component 111, the rotating component 12 and the snap-fit ​​part 1111 are snapped together, and the first end of the supporting component 13 is located in the locked position; when the rotating component 12 continues to rotate in the first direction by a preset angle from the corresponding position of the snap component 111, the first end of the supporting component 13 moves from the locked position to the first unlocked position; when the rotating component 12 rotates in the second direction, the first end of the supporting component 13 moves from the first unlocked position to the second unlocked position, and the snap-fit ​​part 1111 is disengaged from the rotating component 12.

[0116] Exemplarily, when the rotating assembly 12 rotates to the engaging position of the locking component 111 , the rotating assembly 12 and the locking part 1111 are engaged with each other, and the first end of the supporting assembly 13 is located at the locking position.

[0117] When the rotating assembly 12 continues to rotate in the first direction by a preset angle from the engaging position of the buckle component 111, the first end of the supporting assembly 13 moves from the locked position to the first unlocked position; wherein the first unlocked position may be higher than the locked position, and specifically may be one of the connection points between the extended area and the restricted area in the guide groove 112, so as to unlock the locked state of the first end of the supporting assembly 13. For example, the preset angle may be 6°.

[0118] When the rotating component 12 rotates in the second direction, the first end of the supporting component 13 moves from the first unlocking position to the second unlocking position, and the locking part 1111 disengages from the rotating component 12; wherein the second unlocking position can be the position in the guide groove 112 with the largest distance from the elastic component 14.

[0119] It should be noted that when the first end of the support assembly 13 moves to the second unlocking position, it can be said that the distance between the guide block 11 and the elastic assembly 14 is the smallest. At this time, the rotating assembly 12 is completely away from the guide block 11, and the locking structure 10 is in an unlocked state.

[0120] In another embodiment of the present application, a specific implementation method of the locking structure 10 to achieve locking and unlocking is also introduced. For example, Fig. 9 FIG. 1 is another schematic diagram of the structure of the locking structure 10 provided in the embodiment of the present application. Fig. 9 As shown, at least one guide block 11 specifically includes a first guide block 113 and a second guide block 114; the support assembly 13 specifically includes a first support assembly 131 and a second support assembly 132; one end of the first support assembly 131 and the second support assembly 132 are respectively movably arranged in the guide grooves of the first guide block 113 and the second guide block 114; the first guide block 113 and the second guide block 114 are symmetrically arranged on both sides of the pressure plate 15.

[0121] Specifically, when the rotating assembly 12 rotates to the engaging position of the first guide block 113, the engaging parts of the rotating assembly 12 and the first guide block 113 engage with each other, the first end of the first support assembly 131 is located in the locking position, and the first end of the second support assembly 132 is located in the second unlocking position;

[0122] When the rotating assembly 12 rotates from the clamping position of the first guide block 113 to a preset angle in the first direction, the first end of the first supporting assembly 131 moves from the locked position to the first unlocked position, and the first end of the second supporting assembly 132 is located at the second unlocked position;

[0123] When the rotating assembly 12 rotates in the second direction, the first end of the first supporting assembly 131 moves from the first unlocking position to the second unlocking position, the fastening part of the first guiding block 113 is disengaged from the rotating assembly 12, and the first end of the second supporting assembly 132 moves from the second unlocking position to the first unlocking position;

[0124] When the rotating assembly 12 rotates to the engaging position of the second guide block 114, the engaging parts of the rotating assembly 12 and the second guide block 114 engage with each other, the first end of the second support assembly 132 is located in the locking position, and the first end of the first support assembly 131 is located in the second unlocking position.

[0125] The embodiment of the present application further provides a rotatable table top 20. Exemplarily, the rotatable table top 20 includes a locking structure 10, a table top 21, a support plate 22, and a rotating shaft 23. The rotating component 12 of the locking structure 10 is arranged on the table top 21, and the components of the locking structure 10 other than the rotating component 12 are arranged on the support plate 22. The table top 21 and the support plate 22 are connected by the rotating shaft 23; wherein, one end of the support component 13 of the locking structure 10 that is not arranged in the guide groove 112 of the locking structure 10 is fixed to the support plate 22; and the rotating component 12 rotates around the rotating shaft 23.

[0126] In the embodiment of the present application, the coaxial connection between the table top 21 and the support plate 22 can be achieved through the rotating shaft 23, so that when the table top 21 rotates around the rotating shaft 23, its own locking and unlocking can be achieved through the mutual cooperation between its own rotating component and other locking structures on the support plate 22.

[0127] For example, Fig.10 2 is a schematic diagram of the structure of the table top 21 provided in the embodiment of the present application. Fig.10 As shown, the rotating assembly of the locking structure 10 is arranged on the table top 21 . Fig.11 2 is a schematic diagram of the structure of the support plate 22 provided in the embodiment of the present application.

[0128] Combination Fig.10 and Fig.11 , Fig.12 2 is a schematic diagram of the structure of the rotatable table top 20 provided in the embodiment of the present application. Fig.12 As shown, the table top 21 and the support plate 22 are connected via a rotating shaft 23 .

[0129] It should be noted that the circumference of the rotating assembly on the table top 21 close to the rotating shaft 23 is less than half of the circumference of the rotating shaft 23. Secondly, in order to reduce the wear degree of the rotating shaft 23, a bushing is also arranged outside the rotating shaft 23.

[0130] Compared with the prior art in which the locking block is driven by an external driving force to achieve locking or unlocking of the rotatable structure in a rotational state, the rotatable table top 20 provided in the embodiment of the present application can drive the guide block 11 to move by contacting the snap component 111 (disposed on the guide block 11) when the rotating component 12 rotates, so as to drive the first end of the support component 13 to move along the guide groove 112 of the guide block 11 as the guide block 11 moves, and unlock and lock the locking structure 10 when the support component 13 moves to the unlocking position and the unlocking position, respectively, thereby reducing the complexity of the locking structure.

[0131] In another embodiment of the present application, a specific implementation of a locked state of the rotatable table top 20 is also introduced. For example, Fig.13 2 is a schematic diagram of the internal structure of the rotatable table top 20 provided in the embodiment of the present application. Fig.13 As shown in (a), when the first end of the first support assembly 131 is located at the locked position and the first end of the second support assembly 132 is located at the second unlocked position, the rotatable table top 20 is in a folded locked state; Fig.13 As shown in (b), when the first end of the first support assembly 131 moves from the locked position to the first unlocked position and the first end of the second support assembly 132 is located at the second unlocked position, the rotatable table top 20 is unlocked from the folded locked state; Fig.13 As shown in (c), when the first end of the first support component 131 moves from the first unlocked position to the second unlocked position, and the first end of the second support component 132 moves from the second unlocked position to the first unlocked position, the rotatable table top 20 is unlocked and unfolded to the locked state; Fig.13 As shown in (d), when the first end of the second support component 132 moves from the first unlocked position to the locked position and the first end of the first support component 131 is located at the second unlocked position, the rotatable table top 20 is in an unfolded locked state.

[0132] For example, Fig.14 2 is a schematic diagram of the rotatable table top 20 switching to a locked state provided in an embodiment of the present application. Fig.14As shown, the changing process of the locking state of the rotatable table top 20 is specifically as follows: (a) folded locked state - (b) unlocked folded locked state - (c) unlocked unfolded locked state - (d) unfolded locked state.

[0133] In another embodiment of the present application, another specific implementation of the locking state of the rotatable table top 20 is also introduced. For example, Fig.15 FIG. 2 is another working schematic diagram of the internal structure of the rotatable table top 20 provided in the embodiment of the present application. Fig.15 As shown in (a), when the first end of the first support assembly 131 is located at the second unlocking position and the first end of the second support assembly 132 is located at the locking position, the rotatable table top 20 is in the unfolded locking state; Fig.15 As shown in (b), when the first end of the second support assembly 132 moves from the locked position to the first unlocked position and the first end of the first support assembly 131 is located at the second unlocked position, the rotatable table top 20 is unlocked and unfolded to the locked state; Fig.15 As shown in (c), when the first end of the second support assembly 132 moves from the first unlocked position to the second unlocked position, and the first end of the first support assembly 131 moves from the second unlocked position to the first unlocked position, the rotatable table top 20 is unlocked from the folding locked state; Fig.15 As shown in (d), when the first end of the first supporting component 131 moves from the first unlocking position to the locking position and the first end of the second supporting component 132 is located at the second unlocking position, the rotatable table top 20 is in a folded locking state.

[0134] For example, Fig.16 FIG. 2 is another schematic diagram of the rotatable table top 20 switching to a locked state provided in an embodiment of the present application. Fig.16 As shown, the changing process of the locking state of the rotatable table top 20 is specifically as follows: (a) unfolded locking state-(b) unlocked unfolded locking state-(c) unlocked folded locking state-(d) folded locked state.

[0135] In another embodiment of the present application, a vehicle is also provided, which may be provided with the above-mentioned rotatable table top 20.
