Description

Technical Field

[0001] This application generally relates to the field of locking structure technology, and specifically to a locking structure, a rotatable table, and a vehicle. Background Technology

[0002] In existing technologies, locking of rotatable structures is typically achieved using locking blocks. Specifically, when the rotatable structure is rotating, an external driving force can move the locking block (e.g., move it up and down along the edge of the rotatable structure) so that the locking block can come into contact with the dynamically rotating structure, thereby locking the rotatable structure. However, the locking mechanism described above is overly complex.

[0003] Therefore, the locking structures used in the prior art to achieve rotatable locking still have a high degree of complexity. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a locking structure 10, a rotatable table 20, and a vehicle, wherein the locking structure 10 can be locked and unlocked by the movement of the first end of the support component 13 within the guide groove 112 when the rotating component 12 is rotating, thereby reducing the complexity of the locking structure.

[0005] The locking structure 10 is as follows:

[0006] According to a first aspect of this application, a locking structure 10 is provided, comprising: at least one guide block 11, a rotating component 12, and a support component 13; a latching component 111 is provided at one end of the guide block 11 near the rotating component 12, and the rotating component 12 matches the latching component 111; a guide groove 112 is also provided on the guide block 11, a first end of the support component 13 is movably disposed in the guide groove 112, and the other end of the support component 13 is a fixed end;

[0007] The rotating component 12 is used to contact the latching component 111 during rotation, so as to drive the guide block 11 to move through the latching component 111, and drive the first end of the support component 13 to move towards the unlocked position of the guide groove 112 through the guide block 11. When the first end of the support component 13 moves to the unlocked position, the locking structure 10 is in the unlocked state.

[0008] The rotating component 12 is also used to engage with the snap-fit ​​component 111 when it is rotated to the snap-fit ​​position of the snap-fit ​​component 111, and to drive the first end of the support component 13 to move from the unlock position of the guide groove 112 to the locking position of the guide groove 112 through the guide block 11. When the first end of the support component 13 moves to the locking position, the locking structure 10 is locked.

[0009] In addition, the locking structure 10 of this application may also have the following additional technical features:

[0010] In conjunction with the first aspect, in one possible implementation, the locking structure 10 further includes a spring component 14; one end of the spring component 14 is a fixed end, and the other end of the spring component 14 is connected to the guide block 11.

[0011] When the rotating component 12 rotates in the first direction, the rotating component 12 contacts the snap-fit ​​component 111 and drives the guide block 11 to move away from the elastic component 14 through the snap-fit ​​component 111, so as to stretch the elastic component 14.

[0012] When the rotating component 12 rotates in the second direction, the rotating component 12 contacts the latching component 111 and drives the guide block 11 to move towards the elastic component 14 through the latching component 111, and the elastic component 14 rebounds; wherein, the second direction is opposite to the first direction.

[0013] In conjunction with the first aspect, in one possible implementation, when the rotating component 12 rotates in the second direction and disengages from the snap-fit ​​component 111, the guide block 11 moves toward the elastic component 14 under the action of the elastic component 14.

[0014] In conjunction with the first aspect, in one possible implementation, the extension direction of the guide groove 112 matches the movement direction of the guide block 11, and the locking position is located in the limiting area of ​​the guide groove 112.

[0015] In conjunction with the first aspect, in one possible implementation, the guide slot 112 includes a first sub-slot 1121 and a second sub-slot 1122 disposed along the moving direction of the guide block 11.

[0016] In conjunction with the first aspect, in one possible implementation, the locking structure 10 further includes a pressure plate 15, with the rotating component 12 stacked on top of the pressure plate 15, and the rotating component 12 rotating on the pressure plate 15; wherein the thickness of the pressure plate 15 at the end near the elastic component 14 is greater than the thickness of the pressure plate 15 at the end away from the elastic component 14.

[0017] In conjunction with the first aspect, in one possible implementation, the latching component 111 includes a latching part 1111 and a locking part 1112, wherein the latching part 1111 is connected to the locking part 1112; wherein the latching part 1111 contacts the side of the pressure plate 15 near the guide block 11 and matches the rotating assembly 12; the pressure plate 15 and the locking part 1112 are stacked;

[0018] When the rotating assembly 12 rotates to the snap-fit ​​position, the rotating assembly 12 and the snap-fit ​​part 1111 snap into each other and the rotating assembly 12 rotates in the second direction, the snap-fit ​​part 1112 moves along the pressure plate 15 toward the direction close to the elastic assembly 14.

[0019] When the locking part 1112 moves along the pressure plate 15 to the preset position, the locking part 1112 causes the fastening part 1111 to deform, so that the fastening part 1111 disengages from the rotating assembly 12.

[0020] In conjunction with the first aspect, in one possible implementation, the unlocking position includes a first unlocking bit and a second unlocking bit;

[0021] When the rotating assembly 12 rotates to the corresponding position of the latching component 111, the rotating assembly 12 and the fastening part 1111 fasten together, and the first end of the support assembly 13 is in the locked position.

[0022] When the rotating component 12 continues to rotate a preset angle in the first direction from the corresponding position of the latching component 111, the first end of the supporting component 13 moves from the locked position to the first unlocked position;

[0023] When the rotating component 12 rotates in the second direction, the first end of the support component 13 moves from the first unlocking position to the second unlocking position, and the fastening part 1111 disengages from the rotating component 12.

[0024] In conjunction with the first aspect, in one possible implementation, at least one guide block 11 includes a first guide block 113 and a second guide block 114; the support assembly 13 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 disposed 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 disposed on both sides of the pressure plate 15;

[0025] When the rotating assembly 12 rotates to the snap-fit ​​position of the first guide block 113, the fastening parts of the rotating assembly 12 and the first guide block 113 are fastened together, the first end of the first support assembly 131 is in the locked position, and the first end of the second support assembly 132 is in the second unlocked position.

[0026] When the rotating component 12 rotates from the snap-fit ​​position of the first guide block 113 to the first direction by a preset angle, the first end of the first support component 131 moves from the locked position to the first unlocked position, and the first end of the second support component 132 is located in the second unlocked position;

[0027] When the rotating assembly 12 rotates in the second direction, the first end of the first support assembly 131 moves from the first unlocking position to the second unlocking position, the fastening part of the first guide block 113 disengages from the rotating assembly 12, and the first end of the second support assembly 132 moves from the second unlocking position to the first unlocking position.

[0028] When the rotating assembly 12 rotates to the snap-fit ​​position of the second guide block 114, the snap-fit ​​parts of the rotating assembly 12 and the second guide block 114 snap into each other, the first end of the second support assembly 132 is in the locked position, and the first end of the first support assembly 131 is in the second unlocked position.

[0029] According to a second aspect of this application, a rotatable tabletop 20 is provided, comprising a locking structure 10, a tabletop 21, a support plate 22, and a pivot 23. The rotating component 12 of the locking structure 10 is disposed on the tabletop 21, and the components of the locking structure 10 other than the rotating component 12 are disposed on the support plate 22. The tabletop 21 and the support plate 22 are connected by the pivot 23. The end of the support component 13 of the locking structure 10 that is not disposed in the guide groove 112 of the locking structure 10 is fixed to the support plate 22. The rotating component 12 rotates around the pivot 23.

[0030] In conjunction with the second aspect, in one possible implementation, the support component 13 includes a first support component 131 and a second support component 132, and the unlocking positions of the guide groove 112 include a first unlocking position and a second unlocking position;

[0031] When the first end of the first support component 131 is in the locked position and the first end of the second support component 132 is in the second unlocked position, the rotatable table 20 is in the folded and locked state.

[0032] When the first end of the first support component 131 moves from the locked position to the first unlocked position and the first end of the second support component 132 is in the second unlocked position, the table 20 can be rotated to unlock the folding and locking state.

[0033] When the first end of the first support component 131 moves from the first unlock position to the second unlock position and the first end of the second support component 132 moves from the second unlock position to the first unlock position, the rotatable table 20 can be unlocked and unfolded from the locked state.

[0034] When the first end of the second support component 132 moves from the first unlock position to the locked position and the first end of the first support component 131 is in the second unlock position, the rotatable table 20 is in the unfolded and locked state.

[0035] In conjunction with the second aspect, in one possible implementation, when the first end of the first support component 131 is in the second unlocked position and the first end of the second support component 132 is in the locked position, the rotatable table 20 is in the unfolded and locked state.

[0036] When the first end of the second support component 132 moves from the locked position to the first unlocked position and the first end of the first support component 131 is in the second unlocked position, the table 20 can be rotated to unlock and unfold the locked state.

[0037] When the first end of the second support component 132 moves from the first unlock position to the second unlock position and the first end of the first support component 131 moves from the second unlock position to the first unlock position, the tabletop 20 can be rotated to unlock the folding lock state.

[0038] When the first end of the first support component 131 moves from the first unlock position to the locked position and the first end of the second support component 132 is in the second unlock position, the rotatable table 20 is in a folded and locked state.

[0039] According to a third aspect of this application, a vehicle is provided that includes the rotatable table 20 described in the second aspect.

[0040] Compared to existing technologies that rely on external driving force to drive the locking block to lock or unlock the rotatable structure in a rotating state, the locking structure 10, rotatable table 20, and vehicle provided in this application embodiment can drive the guide block 11 to move by contacting the buckle component 111 (set on the guide block 11) when the rotating component 12 rotates. This causes 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. The locking structure 10 is unlocked and locked when the support component 13 moves to the unlock position and the unlock position, respectively, thereby reducing the complexity of the locking structure.

Detailed Implementation

[0061] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0062] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the accompanying drawings and embodiments. Furthermore, the term "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The terms "first" and "second," etc., in the specification and claims of the embodiments of this application are used to distinguish different objects, not to describe a specific order of objects.

[0063] Currently, locking of rotatable structures is typically achieved using locking blocks. For example, when the rotatable structure is rotating, an external driving force can move the locking block so that it can contact the dynamically rotating structure, thereby locking the rotatable structure. For instance, the locking block can be mounted 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 to allow the locking block to move up and down. The external driving force is released when the rotatable structure's slot rotates to the corresponding position of the locking block, causing the locking block to engage with the slot, thus locking the rotatable structure. Secondly, to unlock the rotatable structure, an external driving force needs to be applied to the lever structure again to move the locking block upwards, causing it to disengage from the rotatable structure's slot, thus unlocking the rotatable structure.

[0065] However, the locking mechanism described above, which combines locking blocks and rotatable structures, is overly complex in its locking implementation. Therefore, existing locking structures for locking or unlocking rotatable structures still suffer from high complexity.

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

[0067] In one embodiment of this application, Figure 1 This is a schematic diagram of one type of locking structure 10 provided in an embodiment of this application. For example... Figure 1 As shown, the locking structure 10 includes: at least one guide block 11, a rotating component 12, and a support component 13; a latching component 111 is provided at one end of the guide block 11 near the rotating component 12, and the rotating component 12 matches the latching component 111; a guide groove 112 is also provided on the guide block 11, the first end of the support component 13 is movably disposed in the guide groove 112, and the other end of the support component 13 is a fixed end.

[0068] Specifically, the rotating component 12 is used to contact the latching component 111 during rotation, so as to drive the guide block 11 to move through the latching component 111, and drive the first end of the support component 13 to move towards the unlocking position of the guide groove 112 through the guide block 11. When the first end of the support component 13 moves to the unlocking position, the locking structure 10 is in the unlocked state. It is also used to engage with the latching component 111 when rotating to the latching position of the latching component 111, and drive the first end of the support component 13 from the unlocking position of the guide groove 112 to the locking position of the guide groove 112 through the guide block 11. When the first end of the support component 13 moves to the locking position, the locking structure 10 is in the locked state.

[0069] In this embodiment of the application, the guide block 11 may be provided with a latching component 111 on the side near the rotating component 12, so that when the rotating component 12 rotates to the corresponding position of the latching component 111, it engages with the latching component 111. The corresponding position of the latching component 111 may be the latching position of the latching component 111.

[0070] For example, the structure of the rotating component 12 can be matched with the structure of the snap-fit ​​component 111. Specifically, the rotating component 12 and the snap-fit ​​component 111 can each be provided with concave and convex structures so that they can be engaged by the concave and convex structures when the rotating component 12 and the snap-fit ​​component 111 are in relative positions.

[0071] For example, Figure 2 This is a schematic diagram of the structure of the rotating assembly 12 and the snap-fit ​​component 111 provided in the embodiments of this application. Figure 2 As shown in (a), the rotating component 12 has a convex structure, and the snap-fit ​​component 111 has a concave structure; as Figure 2As shown in (b), when the rotating assembly 12 rotates to the relative position of the snap fastener 111, the rotating assembly 12 engages with the snap fastener 111.

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

[0073] In one possible implementation, the locking structure 10 further includes a support component 13. For example, the size of the support component 13 may match the size of the guide groove 112 so that the first end of the support component 13 can be movably disposed within the guide groove 112.

[0074] Specifically, the width of the first end of the support component 13 can be the same as the width of the guide groove 112. For example, the support component 13 can 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 groove 112; and the length of the extensions at both ends of the pull rod can be the same as the depth of the guide groove 112.

[0075] It should be noted that, in order to maintain the connection between the support component 13 and the guide groove 112, the opening of the guide groove 112 can be set as a limiting opening. For example, the width of the opening of the guide groove 112 can be set to a size smaller than the width of the guide groove 112, so as to prevent the support component 13 from detaching from the guide groove 112 through the opening of the guide groove 112.

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

[0077] For example, the guide block 11 can be moved by the rotating component 12. Specifically, when the rotating component 12 is rotating and in contact with the snap-fit ​​component 111, it can move the guide block 11 by its own rotation; and when the rotating component 12 rotates to the snap-fit ​​position of the snap-fit ​​component 111, it can engage with the snap-fit ​​component 111. The rotating component 12 can rotate around its own midpoint or around its axis of rotation.

[0078] For example, when the guide block 11 moves under the drive of the rotating component 12, the first end of the support component 13 can move to the unlocked position in the guide groove 112, at which time the locking structure 10 is in the unlocked state; while when the rotating component 12 is engaged with the buckle component 111, the first end of the support component 13 can move to the locking position in the guide groove 112, at which time the locking structure 10 is in the locked state.

[0079] It should be noted that the aforementioned locking position can be a limiting point within the guide groove 112. Specifically, when the first end of the support component 13 moves to this limiting point, without rotating the rotating component 12, the first end of the support component 13 is restricted at this limiting point, thereby further ensuring the locking state of the locking structure 10 through the support component 13.

[0080] Compared to existing technologies that rely on external driving force to drive the locking block to lock or unlock the rotatable structure in a rotating state, the locking structure 10 provided in this application embodiment can drive the guide block 11 to move by contacting the snap-fit ​​component 111 (set on the guide block 11) when the rotating component 12 rotates. This causes 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. The locking structure 10 is unlocked and locked when the support component 13 moves to the unlock position and the unlock position, respectively, thereby reducing the complexity of the locking structure.

[0081] In another embodiment of this application, other structural distributions of the locking structure 10 are also described. For example, the locking structure 10 further includes a spring component 14; one end of the spring component 14 is a fixed end, and the other end of the spring component 14 is connected to the guide block 11.

[0082] Specifically, when the rotating component 12 rotates in the first direction, the rotating component 12 contacts the snap-fit ​​component 111 and drives the guide block 11 to move away from the elastic component 14 through the snap-fit ​​component 111, so as to stretch the elastic component 14; when the rotating component 12 rotates in the second direction, the rotating component 12 contacts the snap-fit ​​component 111 and drives the guide block 11 to move closer to the elastic component 14 through the snap-fit ​​component 111, so that the elastic component 14 rebounds.

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

[0084] For example, Figure 3 This is another structural schematic diagram of the locking structure 10 provided in the embodiments of this application, as shown below. Figure 3 As shown, the locking structure 10 also includes a spring component 14, one end of which is a fixed end, and the other end of which is connected to the guide block 11.

[0085] Specifically, a region matching the port of the elastic component 14 can be provided at one end of the guide block 11 near the elastic component 14 to achieve 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 can be pull rings. In this case, a groove matching the size of the pull ring can be provided at one end of the guide block 11 near the tension spring to fit the pull ring into the groove, thereby achieving the connection between the tension spring and the guide block 11.

[0086] In one 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] For example, when the rotating component 12 rotates along the first direction, the rotating component 12 can contact the snap-fit ​​component 111, and when it is rotating, the snap-fit ​​component 111 drives the guide block 11 to move away from the elastic component 14, thereby stretching the elastic component 14; wherein, the first direction can be the direction closer to the guide block 11.

[0088] Specifically, when the rotating component 12 rotates toward the guide block 11, it can press against the latching component 111, thereby driving the guide block to move away from the elastic component 14 through the latching component 111.

[0089] For example, when the rotating component 12 rotates in the second direction and the rotating component 12 is still in contact with the snap fastener 111, the rotating component 12 can drive the guide block 11 to move towards the elastic component 14, at which time 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 latching component 111 disappears, but the rotating assembly 12 and the latching component 111 remain in contact. At this time, the rotating assembly 12 drives the guide block 11 to move closer to the elastic assembly 14 through the latching component 111.

[0091] In another embodiment of this application, the relationship between the guide block 11 and the rotating component 12 during movement is also described. For example, when the rotating component 12 rotates in the second direction and disengages from the snap-fit ​​component 111, the guide block 11 moves toward the elastic component 14 under the action of the elastic component 14; wherein the second direction is opposite to the first direction.

[0092] In this embodiment of the application, when the rotating component 12 rotates in the second direction until it disengages from the snap-fit ​​component 111, the guide block 11 can be moved toward the direction of the elastic component 14 by the elastic force released by the elastic component 14.

[0093] In another embodiment of this application, the specific distribution of the guide groove 112 is also described. For example, the extension direction of the guide groove 112 matches the movement direction of the guide block 11, and the locking position is located in the limiting area of ​​the guide groove 112.

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

[0095] In one possible implementation, the extension direction of the guide groove 112 can be matched with the movement direction of the guide block 11.

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

[0097] In one possible implementation, the locking position can be located in the limiting region of the guide groove 112 to limit the position of the first end of the support component 13. The locking position can be located at the lowest point of the limiting region.

[0098] For example, the limiting region of the guide groove 112 can be connected to the extending direction of the guide groove 112. Specifically, when the locking structure 10 switches from the locked state to the unlocked state, the first end of the support component 13 can move from the limiting region of the guide groove 112 to the extending region.

[0099] For example, Figure 4 This is a schematic diagram of a structure of the guide block 11 provided in an embodiment of this application, as shown below. Figure 4 As shown, the guide groove 112 includes a limiting region 401 and an extension region 402. Specifically, since the guide block 11 moves in a vertical direction, the direction of the extension region of the guide groove 112 is also vertical, and the two ends of the limiting region 401 are connected to the two ends of the extension region 402 respectively. At this time, the lowest point of the extension region 402 is in the locked position.

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

[0101] In this embodiment, a guide groove 112 can be formed by symmetrically arranged first sub-grooves 1121 and second sub-grooves 1122, so that the first end of the support component 13 can unlock and lock the locking structure 10 along the two side sub-grooves respectively.

[0102] For example, such as Figure 4 As shown, the extended region includes a first sub-slot 1121 and a second sub-slot 1122 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-slot 1121 and the second sub-slot 1122 can be structured such that their starting position, ending position and intermediate position are arranged sequentially in the moving direction of the guide block 11 (that is, one end of the support component 13 can be engaged in the intermediate position of the sub-slot), the above-mentioned guide slot 112 can be formed, and no specific restrictions are made here.

[0104] In another embodiment of this application, other structural distributions of the locking structure 10 are also described. Exemplarily, the locking structure 10 further includes a pressure plate 15, and the rotating component 12 is stacked on the pressure plate 15, with the rotating component 12 rotating on the pressure plate 15; wherein the thickness of the pressure plate 15 at the end near the elastic component 14 is greater than the thickness of the pressure plate 15 at the end away from the elastic component 14.

[0105] In this embodiment, a pressure plate 15 can be provided below the rotating component 12 so that the rotating component 12 can rotate on the pressure plate 15. For example, the pressure plate 15 can contact the snap-fit ​​component 111.

[0106] In another embodiment of this application, the specific structural distribution and implementation of the latching component 111 are also described. For example, the latching component 111 specifically includes a latching part 1111 and a positioning part 1112, with the latching part 1111 connected to the positioning part 1112; wherein the latching part 1111 contacts the side of the pressure plate 15 near the guide block 11 and matches the rotating assembly 12; the pressure plate 15 and the positioning part 1112 are stacked.

[0107] Specifically, when the rotating assembly 12 rotates to the snap-fit ​​position, the rotating assembly 12 and the snap-fit ​​part 1111 snap into each other and the rotating assembly 12 rotates in the second direction, the snap-fit ​​part 1112 moves along the pressure plate 15 toward the direction close to the elastic assembly 14; when the snap-fit ​​part 1112 moves along the pressure plate 15 to the preset position, the snap-fit ​​part 1112 causes the snap-fit ​​part 1111 to deform, so that the snap-fit ​​part 1111 disengages from the rotating assembly 12.

[0108] In one possible implementation, Figure 5 This is a schematic diagram of a snap-fit ​​component 111 provided in an embodiment of this application. For example... Figure 5 As shown, the latching component 111 specifically includes a latching part 1111 and a locking part 1112. The latching part 1111 is connected to the locking part 1112; the latching part 1111 is matched with the rotating assembly 12.

[0109] For example, Figure 6 This is an exploded structural diagram of the pressure plate 15 and guide block 11 from one viewpoint provided in the embodiments of this application; as shown Figure 6 As shown, the fastening part 1111 is in contact with the side of the pressure plate 15 near the guide block 11. Figure 7 This is an exploded structural diagram of the pressure plate 15 and guide block 11 from another perspective, as provided in the embodiments of this application; combined with Figure 6 It can be concluded that the pressure plate 15 and the locking part 1112 are stacked.

[0110] Specifically, when the rotating assembly 12 rotates in the first direction, the guide block 11 can move away from the elastic assembly 14. At this time, the locking part 1112 also moves away from the elastic assembly 14 along the pressure plate 15. When the rotating assembly 12 rotates to the locking position of the locking part 111, the rotating assembly 12 and the locking part 1111 are locked together. At this time, the bottom 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 towards the elastic assembly 14. At this time, the locking part 1112 also moves towards the elastic assembly 14 along the pressure plate 15. When the locking part 1112 moves to a preset position along the pressure plate 15, the locking part 1112 can cause the fastening part 1111 to deform, so that the fastening part 1111 disengages from the rotating assembly 12. The preset position can be one end of the pressure plate 15 near 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 This is an exploded structural diagram of the pressure plate 15 and guide block 11 from another perspective, as provided in the embodiments of this application; Figure 8 As shown, when the locking part 1112 moves along the pressure plate 15 to one end of the pressure plate 15 near the elastic component 14, since the end of the pressure plate 15 near the elastic component 14 is thicker, the locking part 1112 causes the fastening part 1111 to deform, thereby causing the fastening part 1111 to disengage from the rotating component 12.

[0114] In another embodiment of this application, a specific implementation method for locking and unlocking the rotating component 12 is also described. For example, the unlocking positions include a first unlocking position and a second unlocking position.

[0115] Specifically, when the rotating component 12 rotates to the corresponding position of the latching component 111, the rotating component 12 and the fastening part 1111 fasten together, and the first end of the support component 13 is in the locked position; when the rotating component 12 continues to rotate a preset angle in the first direction from the corresponding position of the latching component 111, the first end of the support 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 support component 13 moves from the first unlocked position to the second unlocked position, and the fastening part 1111 disengages from the rotating component 12.

[0116] For example, when the rotating assembly 12 rotates to the snap-fit ​​position of the snap-fit ​​component 111, the rotating assembly 12 and the snap-fit ​​component 1111 snap into each other, and the first end of the support assembly 13 is in the locked position.

[0117] When the rotating component 12 continues to rotate a preset angle in the first direction from the snap-fit ​​position of the snap-fit ​​component 111, the first end of the support component 13 moves from the locked position to the first unlocked position; wherein, the first unlocked position may be higher than the locked position, specifically it may be one of the connection points between the extension area and the restriction area within the guide groove 112, for unlocking the locked state of the first end of the support component 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 support component 13 moves from the first unlocking position to the second unlocking position, and the fastening 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 component 13 moves to the second unlock position, it means that the distance between the guide block 11 and the elastic component 14 is the smallest. At this time, the rotating component 12 is completely away from the guide block 11, and the locking structure 10 is in the unlocked state.

[0120] In another embodiment of this application, a specific implementation method for the locking structure 10 to achieve locking and unlocking is also described. For example, Figure 9 This is another structural schematic diagram of the locking structure 10 provided in the embodiments of this application. For example... Figure 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 disposed 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 disposed on both sides of the pressure plate 15.

[0121] Specifically, when the rotating component 12 rotates to the snap-fit ​​position of the first guide block 113, the snap-fit ​​parts of the rotating component 12 and the first guide block 113 snap into each other, the first end of the first support component 131 is in the locked position, and the first end of the second support component 132 is in the second unlocked position.

[0122] When the rotating component 12 rotates from the snap-fit ​​position of the first guide block 113 to the first direction by a preset angle, the first end of the first support component 131 moves from the locked position to the first unlocked position, and the first end of the second support component 132 is located in the second unlocked position;

[0123] When the rotating assembly 12 rotates in the second direction, the first end of the first support assembly 131 moves from the first unlocking position to the second unlocking position, the fastening part of the first guide block 113 disengages from the rotating assembly 12, and the first end of the second support assembly 132 moves from the second unlocking position to the first unlocking position.

[0124] When the rotating assembly 12 rotates to the snap-fit ​​position of the second guide block 114, the snap-fit ​​parts of the rotating assembly 12 and the second guide block 114 snap into each other, the first end of the second support assembly 132 is in the locked position, and the first end of the first support assembly 131 is in the second unlocked position.

[0125] This application embodiment also provides a rotatable tabletop 20. Exemplarily, the rotatable tabletop 20 includes a locking structure 10, a tabletop 21, a support plate 22, and a rotating shaft 23. The rotating component 12 of the locking structure 10 is disposed on the tabletop 21, and the components of the locking structure 10 other than the rotating component 12 are disposed on the support plate 22. The tabletop 21 and the support plate 22 are connected by the rotating shaft 23. The end of the support component 13 of the locking structure 10 that is not disposed within the guide groove 112 of the locking structure 10 is fixed to the support plate 22. The rotating component 12 rotates around the rotating shaft 23.

[0126] In this embodiment, the tabletop 21 and the support plate 22 can be coaxially connected by the pivot 23, so that when the tabletop 21 rotates around the pivot 23, it can lock and unlock itself through the cooperation of its own rotating components and other locking structures on the support plate 22.

[0127] For example, Figure 10 This is a schematic diagram of a tabletop 21 provided in an embodiment of this application. For example... Figure 10 As shown, the rotating component of the locking structure 10 is mounted on the tabletop 21. Figure 11 This is a schematic diagram of a support plate 22 provided in an embodiment of this application. For example... Figure 11 As shown, the components of the locking structure 10, excluding the rotating component, are mounted on the support plate 22.

[0128] Combination Figure 10 and Figure 11 , Figure 12 This is a schematic diagram of a rotatable tabletop 20 provided in an embodiment of this application. For example... Figure 12 As shown, the tabletop 21 and the support plate 22 are connected by a pivot 23.

[0129] It should be noted that the circumference of the rotating component on the tabletop 21 near the pivot 23 is less than half the circumference of the pivot 23. Secondly, in order to reduce the wear of the pivot 23, a bushing is also provided on the outside of the pivot 23.

[0130] Compared to existing technologies that rely on external driving force to drive the locking block to lock or unlock the rotatable structure in a rotating state, the rotatable table 20 provided in this application embodiment can drive the guide block 11 to move by contacting the buckle component 111 (set on the guide block 11) when the rotating component 12 rotates. This causes 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. The locking structure 10 is unlocked and locked when the support component 13 moves to the unlock position and the unlock position, respectively, thereby reducing the complexity of the locking structure.

[0131] In another embodiment of this application, a specific implementation of a locked state of the rotatable tabletop 20 is also described. For example, Figure 13 This is a schematic diagram illustrating the internal structure of the rotatable tabletop 20 provided in an embodiment of this application. For example... Figure 13 As shown in (a), when the first end of the first support component 131 is in the locked position and the first end of the second support component 132 is in the second unlocked position, the rotatable tabletop 20 is in a folded and locked state; Figure 13 As shown in (b), when the first end of the first support component 131 moves from the locked position to the first unlocked position and the first end of the second support component 132 is in the second unlocked position, the tabletop 20 can be rotated to unlock the folding and locking state; as Figure 13 As shown in (c), when the first end of the first support component 131 moves from the first unlocking position to the second unlocking position and the first end of the second support component 132 moves from the second unlocking position to the first unlocking position, the rotatable table 20 can be unlocked and unfolded from its locked state; Figure 13 As shown in (d), when the first end of the second support component 132 moves from the first unlock position to the locked position and the first end of the first support component 131 is in the second unlock position, the rotatable table 20 is in the unfolded and locked state.

[0132] For example, Figure 14 This is a schematic diagram illustrating the switching and locking states of the rotatable tabletop 20 provided in an embodiment of this application. For example... Figure 14As shown, the specific process of the locking state change of the rotatable table 20 is as follows: (a) folded locking state - (b) unlocked folded locking state - (c) unlocked unfolded locking state - (d) unfolded locking state.

[0133] In another embodiment of this application, a specific implementation of another locking state of the rotatable tabletop 20 is also described. For example, Figure 15 This is another schematic diagram of the internal structure of the rotatable tabletop 20 provided in this embodiment. For example... Figure 15 As shown in (a), when the first end of the first support component 131 is in the second unlocked position and the first end of the second support component 132 is in the locked position, the rotatable tabletop 20 is in the unfolded and locked state; Figure 15 As shown in (b), when the first end of the second support component 132 moves from the locked position to the first unlocked position and the first end of the first support component 131 is in the second unlocked position, the rotatable table 20 can be unlocked and the locked state unfolded; as Figure 15 As shown in (c), when the first end of the second support component 132 moves from the first unlocking position to the second unlocking position and the first end of the first support component 131 moves from the second unlocking position to the first unlocking position, the rotatable table 20 can be unlocked from its folding and locking state; Figure 15 As shown in (d), when the first end of the first support component 131 moves from the first unlock position to the locked position and the first end of the second support component 132 is in the second unlock position, the rotatable table 20 is in a folded and locked state.

[0134] For example, Figure 16 This is another schematic diagram illustrating the switching and locking states of the rotatable tabletop 20 provided in this application embodiment. For example... Figure 16 As shown, the specific process of the locking state change of the rotatable table 20 is as follows: (a) unfolded locking state - (b) unlocked unfolded locking state - (c) unlocked folded locking state - (d) folded locking state.

[0135] In another embodiment of this application, a vehicle is also provided, which may be equipped with the aforementioned rotatable table 20.
