In addition, the terms "first" and "second" are only used to distinguish in description and have no special meaning.

[0037] The technical scheme provided by the utility model will be introduced below in combination with the drawings and specific embodiments.

[0038] In combination Figure 1 , Figure 2As shown, the embodiment provides a pivot mechanism, which comprises a first pivot connecting piece 1, a second pivot connecting piece 2 and a hovering structure. The first pivot connecting piece 1 comprises a pivot joint, the first pivot connecting piece 1 is rotationally connected with the second pivot connecting piece 2 through the pivot joint, and the pivot joint is provided with the hovering structure. When the first pivot connecting piece 1 and the second pivot connecting piece 2 are relatively rotated to a preset angle, the hovering structure can provide a locking force to make the first pivot connecting piece 1 and the second pivot connecting piece 2 hover at the preset angle.

[0039] In one embodiment of the embodiment, as shown in Figure 3 As shown, the pivot joint is a pivot shaft 11, and a rotating hole 201 is formed in the second pivot connecting piece 2. One end of the pivot shaft 11 is rotatably inserted into the rotating hole 201. When the pivot shaft 11 rotates, it can drive the first pivot connecting piece 1 to rotate relative to the second pivot connecting piece 2. By using the pivot shaft 11, the rotation of the pivot joint is more stable and reliable. At the same time, the structure of the pivot joint is effectively simplified, and the connection part of the pivot joint and the second pivot connecting piece 2 is more stable and durable. In addition, the hovering structure is arranged at one end of the pivot shaft 11, so that the pivot shaft 11 can stop rotating when it rotates to a preset angle, thereby making the second pivot connecting piece 2 hover.

[0040] In one embodiment of the embodiment, the hovering structure is a friction damping piece, such as a friction ring, a friction plate or a friction pad, etc. When the pivot shaft 11 rotates, the friction damping piece can provide a rotating resistance for the pivot shaft 11 and the second pivot connecting piece 2, so that after the second pivot connecting piece 2 rotates a certain angle relative to the pivot shaft 11, it will not automatically rotate around the pivot shaft 11 under the action of external force, but will be stably hovered at the rotated angle position. Through the above arrangement, the first pivot connecting piece 1 and the second pivot connecting piece 2 can be hovered at any rotating angle, and the controllability is enhanced, which facilitates operation and use. In addition, when the hovering structure adopts the friction damping piece, better damping feeling can be provided for the first pivot connecting piece 1 and the second pivot connecting piece 2 without increasing the installation space, thereby improving the use experience.

[0041] Specifically, in the embodiment, as shown in Figure 3 As shown, the first pivot connecting piece 1 further comprises a pivot seat 12 and a locking piece 13. The pivot seat 12 is used to fixedly connect the first rotating body, preferably threaded connection, so as to facilitate disassembly, and an installation hole 121 is formed in the end of the pivot seat 12. The other end of the pivot shaft 11 is inserted into the installation hole 121 and fixedly connected with the pivot seat 12 through the locking piece 13, so that the pivot shaft 11 can be stably and transmissionally connected with the first rotating body through the pivot seat 12.

[0042] In one embodiment of the embodiment, as shown in Figure 4As shown, the locking piece 13 is designed as a threaded structure, the side wall of the mounting hole 121 is provided with two oppositely arranged slot holes 1211, one of which is arranged through the outer surface of the pivot seat 12, and the other has an internal thread and is arranged through the hole 111 at the other end of the pivot shaft 11, and after the other end of the pivot shaft 11 is inserted into the rotating hole 201, the hole 111 can be arranged concentrically with the two slot holes 1211, and the locking piece 13 can adopt a threaded structure such as a screw or a bolt. When assembling, the threaded segment of the locking piece 13 is sequentially inserted through one of the slot holes 1211 and the hole 111, and is threadedly connected with the other slot hole 1211. The above-mentioned mode not only improves the connection firmness of the pivot shaft 11 and the pivot seat 12, but also facilitates the disassembly and assembly of the pivot seat 12 and the pivot shaft 11. Further, the pivot seat 12 is provided with a rotating hole 201 at each end, and the pivot shaft 11 and the second pivot connecting piece 2 are provided with two, to meet the actual working condition requirements.

[0043] Further specifically, the pivot seat 12 is further provided with a threading hole 122 for threading and restraining the conductive wire bundle, so that when the pivot mechanism is applied to an electronic device, the connecting wire bundle on the electronic device can be restrained and regularized through the threading hole 122, thereby avoiding the scattering of the conductive wire bundle, ensuring safety and improving the aesthetic appearance.

[0044] Specifically, in the present embodiment, referring to Figure 5 , Figure 6 As shown, the second pivot connecting piece 2 is an integral molding structure and comprises a fixed portion 21 in the form of a flat plate and a sleeving portion 22 in the form of a ring, wherein the fixed portion 21 is provided with the rotating hole 201 for fixed connection with the second rotating body through the fastener, and the sleeving portion 22 is wound and arranged on the outer surface of the pivot shaft 11 to realize stable cooperation with the pivot shaft 11. In the specific assembly, the fixed portion 21 and the sleeving portion 22 can be machined first, and then the sleeving portion 22 is sleeved on the other end of the pivot shaft 11, or the second pivot connecting piece 2 with the generated sleeving portion 22 is first attached to one end of the pivot shaft 11, and then the second pivot connecting piece 2 is bent by a machining device to form the sleeving portion 22 wrapped on the pivot shaft 11, and the present utility model is not limited thereto.

[0045] More specifically, the second pivot connecting piece 2 further comprises a reinforcing rib plate 23 fixedly connected between the fixed portion 21 and the sleeving portion 22 to increase the structural strength of the sleeving portion 22 and the fixed portion 21, prevent excessive deformation of the two during rotation due to the rotation torque of the pivot shaft 11, and thereby improve the service durability of the second pivot connecting piece 2.

[0046] Optionally, in the embodiment, an angle limiting structure is further arranged between the pivot joint and the second pivot connection 2, which is arranged to limit the pivot joint when the first pivot connection 1 and the second pivot connection 2 rotate relative to each other, so as to limit the axial rotation stroke of the first pivot connection 1. Through the above arrangement, the angle limiting structure can effectively control the rotation angle of the first pivot connection 1 and the second pivot connection 2, so as to prevent the rotation from being too large or the rotation angle from being too large, thereby helping to improve the use safety of the pivot mechanism.

[0047] Specifically, as shown in Figure 6 、 Figure 7 , the angle limiting structure includes a limiting block 31 and a stop block 32. In one embodiment of the present embodiment, the second pivot connection 2 protrudes a limiting block 31 at the opening of the rotating hole 201, and the outer side wall of the other end of the pivot shaft 11 protrudes a semicircular stop block 32 in the circumferential direction. When one end of the pivot shaft 11 is inserted into the rotating hole 201, the side wall of the stop block 32 can abut against the opening of the rotating hole 201 where the limiting block 31 is not arranged. At this time, the stop block 32 is in a position that can abut against the limiting block 31 when the pivot shaft 11 rotates along the axis. When the pivot shaft 11 rotates relative to the sleeve portion 22 to the maximum preset angle, the limiting block 31 can timely stop on the stop block 32, so that the pivot shaft 11 can immediately stop rotating. This not only has a simple implementation, but also is stable and reliable.

[0048] It should be noted that the circumferential length of the limiting block 31 and the stop block 32 can be adjusted according to actual needs. For example, the longer the circumferential length of the stop block 32, the faster the stop block 32 can abut against the limiting block 31. The shorter the circumferential length of the stop block 32, the larger the rotation angle range of the pivot shaft 11, thereby facilitating the adjustment of the rotation angle range.

[0049] Another object of the present embodiment is to provide a folding device. When the device is in a double folding structure, it includes a first rotating body, a second rotating body, and the above-mentioned pivot mechanism. The first rotating body is connected to the first pivot connection 1 of the pivot mechanism, and the second rotating body is connected to the second pivot connection 2 of the pivot mechanism, so that the first rotating body and the second rotating body are connected to form a foldable structure. Since the above-mentioned pivot mechanism is provided with a hovering structure, the first rotating body and the second rotating body can stably stay at any predetermined angle during the switching process from the unfolded state to the folded state or from the folded state to the unfolded state, which can avoid the device from being suddenly retracted or continuously unfolded, thereby bringing convenience to the user.

[0050] Of course, it can be understood that when the above folding device is a three-fold structure or more folding parts, the pivot mechanism can also be applicable. For example, in a three-fold structure, a pivot mechanism can be added so that the first rotating body and the second rotating body, and the second rotating body and the third rotating body are connected by the pivot mechanism. In this way, the folding device can form more use forms to meet the diversified use requirements. Therefore, the folding device does not limit the number of folding sections, and only needs to increase the corresponding pivot mechanism according to the actual needs.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example.

[0052] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation manner of the present application. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present application.
