[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0043] The utility model provides a rotating shaft assembly 10, such as Figures 1 to 4 As shown, the shaft assembly 10 includes a connecting shaft 11, a sleeve 12 and a damping member 13. The connecting shaft 11 includes a first end 111, a middle portion 112 and a second end 113, one end of the middle portion 112 is connected to the first end 111, and the other end is in a first direction (such as Figure 4The first end 111 is used to connect one of the connecting ears 223a of the rotating structure, and the second end 113 is used to connect the other connecting ear 223a of the rotating structure; the sleeve 12 is rotatably sleeved on the middle part 112, the sleeve 12 is located between the first end 111 and the second end 113, and the sleeve 12 is used to connect the rotating seat 223b of the rotating structure; the damping member 13 is sandwiched between the middle part 112 and the sleeve 12 to provide a damping force when the sleeve 12 rotates relative to the connecting shaft 11. The rotating shaft assembly 10 is installed at the connection of the bracket joint to realize the relative rotation of the corresponding parts in the bracket, and the damping member 13 provided therein can also accurately adjust and maintain the position after rotation, thereby improving the user experience. And by using the rotating shaft assembly 10 of the present application for assembly, it can not only solve the problem of cumbersome assembly process, but also provide a more stable rotation effect.

[0044] Specifically, when installing the rotating shaft assembly 10, it is only necessary to first place the rotating seat 223b between the two connecting ears 223a, and then insert the second end 113 from one of the connecting ears 223a to the other connecting ear 223a, and the installation of the rotating shaft assembly 10 can be completed. At this time, the first end 111 of the connecting shaft 11 is connected to the connecting ear 223a through which the second end 113 initially passes, and the sleeve 12 is connected to the rotating seat 223b. Compared with the embodiment of the prior art that requires two shaft cores and two damping sleeves, the rotating shaft assembly 10 can be assembled through a single operation process, and the assembly time is short. At the same time, only one connecting shaft 11 is set to achieve rotation, which can also avoid the problem of misalignment caused by assembly errors, and make the rotation more stable.

[0045] Reference Figure 4 and Figure 5 In one embodiment, the damping member 13 is a damping ring sleeved on the middle portion 112, and a convex bulge group 131 is provided on the outer wall of the damping ring, and the convex bulge group 131 abuts against the inner wall of the sleeve 12 to provide a damping force when the sleeve 12 rotates relative to the connecting shaft 11. The provision of the convex bulge group 131 not only provides the required damping force and ensures that the damping ring can stably maintain a relative rotation position, but also reduces the contact area between the damping ring and the sleeve 12 when the damping ring and the sleeve 12 are assembled, reduces the friction force, and thus makes the damping ring and the sleeve 12 assembled more smoothly. Specifically, the damping ring can be a metal part or a rubber part.

[0046] Furthermore, the convex humps group 131 includes a plurality of convex humps 131a, which are arranged at intervals along the circumference of the outer wall. In this way, during the rotation process, the plurality of convex humps 131a can evenly share the pressure, making the rotation more stable. At the same time, the reduced pressure on each convex hump 131a also means less wear and longer service life. In addition, the arrangement of multiple convex humps 131a can relatively ensure the coaxiality of the middle part 112 during rotation, which is conducive to smooth rotation.

[0047] In addition, the addition of the convex hump group 131 can also increase the contact area between the convex hump group 131 and the inner wall of the sleeve 12 in the circumferential direction of the outer wall, so as to increase the friction force, thereby increasing the damping force. Due to the increase in the damping force, the relative position after adjustment is more reliable. Even if it is disturbed or vibrated by the outside, the rotating structure can be maintained in the predetermined position, thereby improving the stability of the overall structure.

[0048] Specifically, the convex hull group 131 includes four convex hulls 131 a , and the four convex hulls 131 a are arranged at equal intervals along the circumferential direction of the outer side wall.

[0049] Preferably, the convex hump 131a extends in the circumferential direction, and the side of the convex hump 131a facing the inner wall has an arc-shaped surface, so as to further increase the contact area between the single convex hump 131a and the inner wall and maintain sufficient contact and close contact between the two.

[0050] Furthermore, there are a plurality of convex bulge groups 131, and the plurality of convex bulge groups 131 are arranged at intervals in the first direction. In this way, more convex bulge groups 131 mean that the pressure can be further shared, making the rotation more stable. At the same time, the arrangement of a plurality of convex bulge groups 131 can further increase the contact area between the damping member 13 and the inner side wall of the sleeve 12 in the axial direction, increase the friction force to increase the damping force, and during the rotation process, the damping member 13 can provide a stronger damping effect, making the performance of the shaft assembly 10 more reliable. Exemplarily, in this embodiment, there are two convex bulge groups 131, and the two convex bulges 131a are evenly arranged on the outer side wall.

[0051] Reference Figure 5 In one embodiment, the damping member 13 includes two end walls 132 arranged opposite to each other in the first direction, and an opening 133 communicating with the internal space of the damping member 13 is provided on the outer side wall, and the opening 133 extends in the first direction and penetrates the two end walls 132. In this way, the damping member 13 is a non-enclosed semi-open ring damping ring, and the semi-open ring damping ring has a certain elastic deformation capacity, which can be appropriately deformed when needed to better adapt to the sleeve 12 and the middle part 112, provide better connection and fastening effect, and make assembly more convenient.

[0052] Reference Figure 4In one embodiment, a plurality of damping members 13 are provided, and the plurality of damping members 13 are arranged in parallel in the first direction. With such an arrangement, when the plurality of damping members 13 are assembled, a single damping member 13 is subjected to less resistance during the assembly process, and is more conducive to cooperation with the middle portion 112 and the sleeve 12. In addition, the advantage of such a design is that dividing the damping member 13 into a plurality of damping members can provide greater flexibility. The number of damping members 13 can be increased or decreased as required to adjust the damping effect to adapt to different working conditions, or the middle portion 112 of different lengths can be satisfied by increasing or decreasing the damping members 13, without the need to set a specific matching damping member 13 due to the length adjustment of the middle portion 112, which is more suitable for large-scale production. By way of example, in this embodiment, two damping members 13 are provided, and the two damping members 13 are mounted in parallel on the middle portion 112.

[0053] There are many ways to connect the shaft assembly 10 with the connecting ear 223a and the rotating seat 223b. For example, in one embodiment, the first end 111, the second end 113 and the sleeve 12 are provided with a slot arranged along the first direction on the outside, and the connecting ear 223a and the rotating seat 223b are provided with a block correspondingly. After the shaft assembly 10 is inserted into the connecting ear 223a and the rotating seat 223b, the block will be accommodated in the slot, thereby connecting the shaft assembly 10 with the connecting ear 223a and the rotating seat 223b; in another embodiment, the first end 111 and the second end 113 are respectively interference fit with the two connecting ears 223a, and the sleeve 12 is interference fit with the rotating seat 223b, for example, by riveting, the shaft assembly 10 is directly inserted into the connecting ear 223a and the rotating seat 223b, so that the first end 111 and the second end 113 are respectively interference fit with the two connecting ears 223a, and the sleeve 12 is interference fit with the rotating seat 223b.

[0054] In order to facilitate the interference fit between the first end 111 and the second end 113 and the two connecting ears 223a, the sleeve 12 and the rotating seat 223b are respectively interference fit. Figure 4 In a specific embodiment, the outer contour of the first end 111 is larger than the outer contour of the sleeve 12, and the outer contour of the second end 113 is smaller than the inner contour of the sleeve 12. In this way, the sleeve 12 can be inserted from the second end 113 to the middle part 112, and the first end 111 can limit the sleeve 12 to prevent the sleeve 12 from being separated from the connecting shaft 11, making it easier to assemble the shaft assembly 10.

[0055] Reference Figure 4, further, the length of the sleeve 12 in the first direction is greater than the length of the first end 111 and the second end 113 in the first direction. Such a configuration is more conducive to the first end 111 and the second end 113 respectively matching with the corresponding connecting ears 223a. For example, one connecting ear 223a is provided with a first connecting hole adapted to the first end 111, and the other connecting ear 223a is provided with a second connecting hole adapted to the second end 113. During the assembly process, the sleeve 12 can be preliminarily connected with the rotating seat 223b first, and then the second end 113 and the first end 111 are respectively connected with the second connecting hole and the first connecting hole until the entire shaft assembly 10 is installed to the preset installation position. During the initial installation stage, the sleeve 12 is only subjected to the connection resistance with the rotating seat 223b, thus avoiding interference between the second end 113 and the first end 111, making the assembly smoother. At the final stage of the connection between the sleeve 12 and the rotating seat 223b, the second end 113 and the first end 111 are connected to the corresponding connecting ears 223a, thus effectively reducing the occurrence of installation jams.

[0056] Preferably, the length of the second end 113 is greater than and equal to the length of the first end 111, so as to achieve synchronous connection and installation with the corresponding connecting ear 223a. Exemplarily, the length of the sleeve 12 can be 8mm, and the second end 113 and the first end 111 are both 3mm.

[0057] Reference Figure 6 Furthermore, the first end 111, the second end 113 and the outer side of the sleeve 12 are all provided with a limiting protrusion 114. A plurality of limiting protrusions 114 are provided, and the plurality of limiting protrusions 114 are arranged at intervals along the circumferential direction. The setting of the limiting protrusions 114 can limit and fix the first end 111, the second end 113 and the sleeve 12, thereby improving the reliability of the connection.

[0058] Furthermore, the limiting protrusion 114 is a convex strip 114a extending along the first direction, and the convex strip 114a has a narrowing trend in the direction away from the center line of the connecting shaft 11 to increase the contact area with the connecting ear 223a or the rotating seat 223b, making the connection more secure.

[0060] Specifically, the mobile terminal bracket 1000 can be a desktop bracket. Specifically, the desktop bracket includes a base 100, a support arm 110 and a support plate 120. The base 100 is used to be placed on a desktop, and the support member 120 is used to fix electronic products such as mobile phones and tablets. The two ends of the support arm 110 are rotatably connected to the base 100 and the support plate 120 through a rotating shaft assembly 10 respectively, so as to adjust the placement angle, making it convenient for users to observe the mobile phone screen.
