[0062] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0063] The following is combined Figures 1-8 The following describes embodiments of the present invention.

[0064] According to an embodiment of this utility model, a rotating mechanism is provided, including a first connecting structure 1, a second connecting structure 2, a locking member 4, and a pressing structure 5; the first connecting structure 1 and the second connecting structure 2 are rotatably connected; a mating structure 3 is provided between the first connecting structure 1 and the second connecting structure 2; the locking member 4 has a locking position that can cooperate with the mating structure 3 and an unlocking position that is disengaged from the mating structure 3; when the locking member 4 is in the locking position, it can restrict the rotation of the first connecting structure 1 relative to the second connecting structure 2; when the locking member 4 is in the unlocking position, the first connecting structure 1 can rotate relative to the second connecting structure 2; the locking position corresponds to the position of the mating structure 3, and the unlocking position is located on the side of the mating structure 3 away from the pressing structure 5; the pressing structure 5 can drive the locking member 4 to switch between the unlocking position and the locking position. This application sets the unlocking position on the side of the mating structure 3 away from the pressing structure 5, which can effectively improve the compactness of the structure and broaden the application scenarios of the product. In this application, the locking position corresponds to the position of the mating structure 3, as long as the locking member 4 can cooperate with the mating structure 3 to restrict the relative rotation of the first connecting structure 1 and the second connecting structure 2. The locking position can also be on one side of the mating structure 3. In this application, the locking element 4 and the mating structure 3 can be a buckle and a latch that can engage with each other; in this case, the locking position is the position where the buckle and the latch can engage, and the unlocking position is the position where they are disengaged; or, the locking element 4 and the mating structure 3 can be a pin and a socket that can be inserted into each other; in this case, the locking position is the pin inserted into the socket, and the unlocking position is the pin extending out of the socket.

[0065] In some embodiments, the switching between the unlocked position and the locked position of the locking member 4 is a switching of the position of the locking member 4 relative to the mating structure 3, that is, the relative movement of the locking member 4 and the mating structure 3.

[0066] In some embodiments, the number of locking elements 4 can be set to one or more; when one of the locking elements 4 is in the locked position, the rotation of the first connecting structure 1 and the second connecting structure 2 can be restricted; when all the locking elements 4 are in the unlocked position, the first connecting structure 1 and the second connecting structure 2 can be unlocked.

[0067] In some embodiments, the pressing structure 5 is subjected to force, including the pressing force exerted on the pressing structure 5 when pressed by a user; and the restoring force from the return structure 6 to reset the pressing structure 5. The pressing structure 5 is driven by the pressing force and the restoring force to switch the locking member 4 between an unlocked position and a locked position.

[0068] In some embodiments, the mating structure 3 may be disposed on the first connecting structure 1; or it may be disposed on the second connecting structure 2; the mating structure 3 may also be disposed on both the first connecting structure 1 and the second connecting structure 2; the mating structure 3 may also move between the first connecting structure 1 and the second connecting structure 2, that is, it may move from the first connecting structure 1 to the second connecting structure 2, or it may move from the second connecting structure 2 to the first connecting structure 1.

[0069] This application also discloses some embodiments in which the mating structure 3 is movably disposed between the first connecting structure 1 and the second connecting structure 2; the pressing structure 5 can drive the mating structure 3 and / or the locking member 4 to move, so that the locking member 4 switches between an unlocked position and a locked position. In this application, the pressing structure 5 drives at least one of the mating structure 3 and the locking member 4 to move relative to each other, thereby switching the position of the locking member 4, which is simple to operate and convenient to use.

[0070] In some embodiments, the pressing structure 5 can drive the locking member 4 to move, and the cooperating structure 3 is fixed between the first connecting structure 1 and the second connecting structure 2; then the locking member 4 can move between the unlocked position and the locked position.

[0071] In some embodiments, the pressing structure 5 can drive the mating structure 3 to move, and the locking member 4 is fixedly set; then the mating structure 3 moves, that is, relative movement occurs between the locking member 4 and the mating structure 3. At this time, the locking member 4 can switch between the unlocked position and the locked position.

[0072] In some embodiments, the pressing structure 5 drives the locking member 4 to move, and at the same time, or with a certain time difference, the driving coordination structure 3 moves; if the speeds of the two movements are different, they can still generate relative movement between them. At this time, the locking member 4 can switch between the unlocked position and the locked position.

[0073] This application also discloses some embodiments in which the number of pressing structures 5 is set to two or more; a mating structure 3 is disposed between each pressing structure 5; when the force on each pressing structure 5 is different, the mating structure 3 can be driven to move, so that the locking member 4 switches between the unlocked position and the locked position. By driving the mating structure 3 to move and switch the position of the locking member 4 through the different forces on each pressing structure 5, the operation is simple and convenient. In this application, one or more pressing structures 5 can be unforced, in which case the force on the pressing structure 5 is 0.

[0074] For example, if two pressing structures 5 are provided, pressing one pressing structure 5 will result in a pressing force (i.e., the force it receives) being greater than zero; if the other pressing structure 5 is not pressed, the force it receives is zero. Since the force on one pressing structure 5 is greater than the force on the other, it can drive the mating structure 3 to move, causing the position of the locking member 4 relative to the mating structure 3 to change, thus switching the position of the locking member 4. In this application, the number of pressing structures 5 can also be three, four, or five.

[0075] In some embodiments, the number of pressing structures 5 is set to two or more, and each pressing structure 5 is provided with a locking element 4; then, during the operation of the driving and cooperating structure 3, each locking element 4 can switch positions. That is, the pressing structure 5 gradually switches the positions of each locking element 4 during the operation.

[0076] In some embodiments, during the pressing process, the pressing structure 5 drives the mating structure 3 to move. During this movement, the mating structure 3 first moves the locking member 4 on the first pressing structure 5 relative to the mating structure 3 so that it is away from the pressing structure 5, at which point the locking member 4 on the first pressing structure 5 is in the unlocked position. The mating structure 3 continues to move, causing the locking member 4 on the second pressing structure 5 to move relative to the mating structure 3 so that it is away from the pressing structure 5, at which point the locking member 4 on the second pressing structure 5 is in the unlocked position. Similarly, the locking members 4 on each pressing structure 5 are unlocked sequentially. When all locking members 4 move relative to the mating structure 3 so that the mating structure 3 is away from the corresponding pressing structure 5, all locking members 4 are in the unlocked position, at which point the first connecting structure 1 and the second connecting structure 2 are unlocked.

[0077] This application also discloses some embodiments in which the mating structure 3 includes a mating ring 31, and a mating portion 311 is provided on the inner peripheral wall of the mating ring 31; the mating portion 311 is used to cooperate with the locking member 4 to restrict the rotation of the first connecting structure 1 relative to the second connecting structure 2; the locking member 4 is disposed on the inner peripheral side of the mating ring 31. The locking member 4 is disposed on the inner peripheral side of the mating ring 31 to further improve the structural compactness.

[0078] In some embodiments, the locking member 4 is movably disposed on the pressing structure 5 such that the locking member 4 is movably located on the inner circumferential side of the mating ring 31. The direction of movement of the locking member 4 is the axial direction of the mating ring 31. The axial direction of the mating ring 31 is also the direction of the rotation axis of the first connecting structure 1 and the second connecting structure 2.

[0079] In some embodiments, the locking member 4 is fixedly disposed on the pressing structure 5; the pressing structure 5 is movable enough to drive the locking member 4 to move axially in the mating ring 31.

[0080] In some embodiments, the locking member 4 is fixedly disposed on the pressing structure 5, and the mating ring 31 is movably disposed between the first connecting structure 1 and the second connecting structure 2; the pressing structure 5 can drive the mating ring 31 to move in its own axial direction.

[0081] This application also discloses some embodiments in which the pressing structure 5 includes a button and an extension connected to each other, the extension extending in the pressing direction of the pressing structure 5; the extension is disposed on the inner circumferential side of the mating ring 31; the locking member 4 is disposed on the extension; the pressing structure 5 moves, driving the extension to move, thereby driving the locking member 4 to move, such a configuration makes the movement of the locking member 4 more stable, and the unlocking and locking more accurate and stable.

[0082] In some embodiments, the locking element 4 is movably disposed on the extension.

[0083] This application also discloses some embodiments in which the locking member 4 is axially movable in the mating ring 31; this further improves the structural compactness of the product, enabling the rotating mechanism to be used in a smaller space and increasing the applicability of the product.

[0084] This application also discloses some embodiments in which the mating part 311 and the locking member 4 respectively include a first concave-convex structure and a second concave-convex structure that are adapted to each other; locking is achieved by the concave-convex mating structure 3. When the locking member 4 moves relative to the mating ring 31 in the axial direction of the mating ring 31, the first concave-convex structure and the second concave-convex structure can disengage from each other. At this time, the locking member 4 moves to the unlocked position so that the first connecting structure 1 and the second connecting structure 2 can rotate relative to each other.

[0085] In some embodiments, the first concave-convex structure includes a groove; the second concave-convex structure includes a protrusion; at least one groove is provided on the inner peripheral wall of the mating ring 31, and the locking member 4 includes at least one protrusion, i.e., the first groove; the protrusion and the groove are provided in a one-to-one correspondence. Alternatively, at least one protrusion is provided on the inner peripheral wall of the mating ring 31, and the locking member 4 includes at least one groove, with the protrusion and the groove being provided in a one-to-one correspondence.

[0086] In some embodiments, there are at least two first concave-convex structures and at least two second concave-convex structures. The first concave-convex structures are arranged sequentially along the circumferential direction of the inner peripheral wall of the mating ring 31, and may be evenly or unevenly arranged. The second concave-convex structures, i.e., the locking members 4, are arranged sequentially along the circumferential direction of the outer peripheral wall of the extension, and may be evenly or unevenly arranged.

[0087] This application also discloses some embodiments in which the direction of movement of the locking member 4 relative to the mating structure 3 is parallel to the rotation axis of the first connecting structure 1 and the second connecting structure 2; this arrangement makes the operation of the locking member 4 more stable and precise, and reduces wear on the various components.

[0088] This application also discloses some embodiments in which the direction of movement of the cooperating structure 3 is parallel to the direction of pressing of the pressing structure 5; thus making the structure simpler and reducing production and manufacturing costs.

[0089] This application also discloses some embodiments in which, when the number of pressing structures 5 is set to two or more and the locking member 4 is disposed on at least one pressing structure 5, the locking members 4 on each pressing structure 5 are arranged sequentially in the axial direction of the mating ring 31; this allows the locking member 4 corresponding to each pressing structure 5 to move relative to the mating ring 31 between the unlocked position and the locked position when the pressing structure 5 drives the mating ring 31 to move in the axial direction.

[0090] This application also discloses some embodiments in which at least one locking element 4 is provided on each pressing structure 5, and the locking elements 4 are arranged sequentially in the circumferential direction of the mating ring 31 on the pressing structure 5.

[0091] This application also discloses some embodiments. The pressing structure 5 includes a first pressing structure 51 and a second pressing structure 52; the locking member 4 includes a first locking member 41 disposed on the first pressing structure 51; the second pressing structure 52 is provided with a first pushing part 521; the second pressing structure 52 can drive the first pushing part 521 to drive the cooperating structure 3 to move, so that the first locking member 41 can be located on the side of the cooperating structure 3 away from the first pressing structure 51, thereby allowing the first locking member 41 to switch to the unlocked position. The first pressing structure 51 and the second pressing structure 52 are independent of each other but also work together, which facilitates modular assembly of the product. Through the linkage between the first pushing part 521 and the cooperating structure 3, the convenient operation of "one-click unlocking" is realized, reducing the user's learning cost. The design of the first pushing part 521 and the cooperating structure 3 can optimize the force transmission path, making the unlocking force more balanced, especially suitable for scenarios that require one-handed operation or are sensitive to force.

[0092] In this application, the number of first pressing structures 51 can be set to one or more, and the number of second pressing structures 52 can also be set to one or more.

[0093] This application also discloses some embodiments, in which the locking member 4 further includes a second locking member 42 disposed on the second pressing structure 52; the second pressing structure 52 moves in a first direction, which can drive the second locking member 42 to move to the side of the mating structure 3 away from the second pressing structure 52, so that the second locking member 42 switches to the unlocked position; the second pressing structure 52 continues to move in the first direction, and the first pushing part 521 can drive the mating structure 3 to move, so that the first locking member 41 can be located on the side of the mating structure 3 away from the first pressing structure 51, thereby switching the first locking member 41 to the unlocked position. Only by applying force to the second pressing structure 52, the first locking member 41 and the second locking member 42 can be switched to the unlocked position simultaneously to unlock the first connecting structure 1 and the second connecting structure 2, so that the first connecting structure 1 can rotate relative to the second connecting structure 2, which is simple to operate and highly efficient.

[0094] This application also discloses some embodiments in which a second pushing part 511 is provided on the first pressing structure 51. The first pressing structure 51 moves in a second direction, driving the first locking member 41 to move away from the first pressing structure 51, thereby switching the first locking member 41 to the unlocked position. As the first pressing structure 51 continues to move in the second direction, the second pushing part 511 drives the cooperating structure 3 to move, so that the second locking member 42 can be located on the side of the cooperating structure 3 away from the second pressing structure 52, thereby switching the second locking member 42 to the unlocked position. By providing two pushing parts, pressing either the first pressing structure 51 or both of the second pressing structures 52 simultaneously switches both the first locking member 41 and the second locking member 42 to the unlocked position, making it more convenient to use.

[0095] This application also discloses some embodiments in which the first pressing structure 51 and the second pressing structure 52 are arranged opposite to each other; and the pressing directions of the first pressing structure 51 and the second pressing structure 52 are opposite; the cooperating structure 3 is disposed between the first pressing structure 51 and the second pressing structure 52. The first pressing structure 51 and the second pressing structure 52 apply force in opposite directions (such as pressing up and down or pushing left and right), which makes it more convenient for the user. In addition, the cooperating structure 3 is centrally located, so that the two pressing structures 5 are symmetrically distributed along the central axis, which can greatly compress the lateral or longitudinal space; further improving the compactness of the structure.
