[0035] Wearable products such as smart watches are favored by consumers because of their small size, portability, and functions such as calling, video, and shooting. The shooting angle of the camera of most smart watches on the market is usually set upward, that is, the shooting angle is perpendicular to the screen display surface of the smart watch, so when the user uses the camera to shoot or video, the user needs to raise the arm to adjust the angle of view, so that the screen is directly opposite the face or other area, so it is difficult to maintain normal shooting or video call for a long time. Therefore, some smart watches are provided with a rotating shaft assembly to adjust the shooting angle of the display screen and the camera thereon.

[0036] However, in order to ensure the rotating feeling, the current watch rotating shaft assembly is provided with a damping reel between the outer peripheral wall of the rotating shaft and the inner peripheral wall of the rotating shaft hole, so that the radial size and the axial size of the rotating shaft assembly are large, the whole machine space is large, and the miniaturization of the smart watch is not conducive.

[0037] In order to alleviate or solve the above technical problems, the utility model provides a new rotating connection structure, including first connecting seat 10, second connecting seat 20 and damping structure 30, damping structure 30 includes friction sheet 31 and elastic sheet 32, the connecting plate 11 of first connecting seat 10, friction sheet 31 and elastic sheet 32 are all set on the rotating shaft 21 of second connecting seat 20 along the axial direction, the radial space is less, can reduce the size of rotating connection structure in radial direction, and, the structure on rotating shaft 21 is all sheet structure, on the basis of being able to provide sufficient friction force, still can reduce the size of rotating connection structure in axial direction.

[0038] The rotating connection structure provided by the embodiment of the utility model will be described. The rotating connection structure is used to realize the relative rotation between two structural members.

[0039] Please see Figures 1 to 4 , the rotating connection structure includes first connecting seat 10, second connecting seat 20 and damping structure 30, first connecting seat 10 has connecting plate 11, the rotating shaft hole 110 is set on connecting plate 11, second connecting seat 20 is provided with rotating shaft 21, rotating shaft 21 passes through rotating shaft hole 110 and is set, damping structure 30 includes friction sheet 31 for increasing the rotating friction between rotating shaft 21 and rotating shaft hole 110 and elastic sheet 32 for making connecting plate 11 and second connecting seat 20 mutually compress, connecting plate 11, friction sheet 31 and elastic sheet 32 are all set on rotating shaft 21 along the axial direction.

[0040] First connecting seat 10 is one of the structural members in the rotating connection structure, and the first connecting seat 10 can be connected to the main body or other components. The first connecting seat 10 has a connecting plate 11, which is a plate-shaped structure. The size of one direction of the connecting plate 11 is much smaller than the size of the other direction, which is the thickness direction. The rotating shaft hole 110 is provided on the connecting plate 11, and the rotating shaft hole 110 penetrates the connecting plate 11 along the thickness direction of the connecting plate 11.

[0041] The second connecting seat 20 is provided with a rotating shaft 21, and the rotating shaft 21 is arranged through the rotating shaft hole 110 of the connecting plate 11, so as to realize the rotating connection of the first connecting seat 10 and the second connecting seat 20.

[0042] The damping structure 30 is used for increasing the rotating friction force between the first connecting seat 10 and the second connecting seat 20. The damping structure 30 comprises a friction sheet 31 and an elastic sheet 32, both of which are sheet-shaped structures, the friction sheet 31 is provided with a first through hole, and the elastic sheet 32 is provided with a second through hole, the friction sheet 31 and the elastic sheet 32 are sleeved on the rotating shaft 21, that is, the rotating shaft 21 is arranged through the first through hole and the second through hole. The connecting plate 11, the friction sheet 31 and the elastic sheet 32 are all axially sleeved on the rotating shaft 21, and the "axial direction" refers to the axial direction of the rotating shaft 21, and it can be understood that the connecting plate 11, the friction sheet 31 and the elastic sheet 32 respectively occupy part of the axial space, and the arrangement order is not necessarily arranged in the order of the connecting plate 11, the friction sheet 31 and the elastic sheet 32, and the arrangement order is not limited here.

[0043] The axial end surface of the friction sheet 31 is in contact with the adjacent structure, which can increase the friction force when the first connecting seat 10 and the second connecting seat 20 rotate relative to each other, and ensure the stability of the rotating connection structure in use. The elastic sheet 32 can press the connecting plate 11 and the second connecting seat 20 in the axial direction, so as to increase the friction force when the first connecting seat 10 and the second connecting seat 20 rotate relative to each other, and ensure the stability of the rotating connection structure in use.

[0044] In the related art, the damping structure 30 is arranged between the outer peripheral wall of the rotating shaft 21 and the inner peripheral wall of the rotating hole 110, so that the radial size (perpendicular to the axial direction of the rotating shaft 21) of the rotating connection structure is relatively large, that is, the outer diameter is relatively large. Moreover, when the damping structure 30 is in contact with the outer peripheral wall of the rotating shaft 21 and the inner peripheral wall of the rotating hole, a relatively large contact area is required to ensure a certain rotating friction force, so the axial size of the damping structure 30 is relatively large. In the embodiments provided by the utility model, the damping structure 30 is in a sheet-shaped structure, and the damping structure 30 and the rotating plate are arranged on the rotating shaft 21 in the axial direction, which reduces the axial size and the radial size of the rotating connection structure, and the pressure between the two connecting seats can be increased by the arrangement of the elastic sheet 32, so as to ensure a certain rotating friction force.

[0045] The rotating connection structure in the above embodiments comprises a first connecting seat 10, a second connecting seat 20 and a damping structure 30, the damping structure 30 comprises a friction sheet 31 and an elastic sheet 32, the rotating shaft 21 of the second connecting seat 20 passes through the connecting plate 11 of the first connecting seat 10, and the damping structure 30 is sleeved on the rotating shaft, the connecting plate 11, the friction sheet 31 and the elastic sheet 32 are all arranged in the axial direction of the rotating shaft 21. Compared with the structure in which the damping structure 30 is located between the outer peripheral wall of the rotating shaft 21 and the inner peripheral wall of the rotating hole 110, the outer diameter size and the axial size of the rotating connection structure are greatly reduced, and the size of the rotating connection structure can be reduced, which is beneficial to the miniaturization of the intelligent host and the intelligent watch.

[0046] Please refer to some embodiments of this utility model. Figures 1 to 4 The connecting plate 11 has a first surface 111 facing the second connecting seat 20 and a second surface 112 facing away from the second connecting seat 20. Friction pieces 31 are disposed on the first surface 111 and / or the second surface 112. The first surface 111 and the second surface 112 of the connecting plate 11 are arranged opposite to each other. It can be understood that the first surface 111 and the second surface 112 of the connecting plate 11 are the two surfaces with larger areas, respectively located on the two surfaces of the connecting plate 11 in the thickness direction. When the friction piece 31 is located on the first surface 111, the friction piece 31 is in contact with the first surface 111 of the connecting plate 11, increasing the rotational friction force; when the friction piece 31 is located on the second surface 112, the friction piece 31 is in contact with the second surface 112 of the connecting plate 11, increasing the rotational friction force.

[0047] The above embodiments include the following three cases: a friction plate 31 is provided on the first surface 111 of the connecting plate 11; or, a friction plate 31 is provided on the second surface 112 of the connecting plate 11; or, friction plates 31 are provided on both the first surface 111 and the second surface 112 of the connecting plate 11. The first surface 111 and the second surface 112 are both surfaces of the connecting plate 11 with large areas, and the contact area with the friction plate 31 is also large. Therefore, even when the number of friction plates 31 is small, a certain rotational friction force can still be maintained, which can further reduce the axial dimension of the rotating connection structure.

[0048] Please refer to some embodiments of this utility model. Figure 1 and Figure 2 The second connecting seat 20 has a third surface 22 facing the connecting plate 11. There are two friction plates 31. The third surface 22, the connecting plate 11, one of the friction plates 31, the elastic plate 32, and the other friction plate 31 are arranged sequentially along the axial direction. The rotating shaft 21 is formed by a protrusion from the third surface 22. The first surface 111 of the connecting plate 11 faces the third surface 22, and the second surface 112 of the connecting plate 11 faces away from the third surface 22. The elastic plate 32 is in a compressed state, capable of pressing one of the friction plates 31 and the connecting plate 11 tightly against the third surface 22. When the first connecting seat 10 and the second connecting seat 20 rotate relative to each other, the first surface 111 of the first connecting seat 10 and the third surface 22 of the second connecting seat 20 come into contact with each other and rotate relative to each other. The first surface 111 and the third surface 22 are pressed together by the pressure provided by the elastic sheet 32, which can improve the rotational friction between them. The second surface 112 of the first connecting seat 10 and one of the axial end faces of the friction sheet 31 come into contact with each other and rotate relative to each other. The second surface 112 and the friction sheet 31 are pressed together by the pressure provided by the elastic sheet 32, which can improve the rotational friction between them.

[0049] The rotating friction between the first connecting seat 10 and the second connecting seat 20 can be increased by pressing the connecting plate 11 between the third surface 22 of the second connecting seat 20 and the friction plate 31, so that the stable rotation between the two rotating seats is ensured. Moreover, the elastic sheet 32 is located between the two friction plates 31, and the elastic sheet 32 between the two friction plates 31 is protected.

[0050] In some embodiments, the number of elastic sheets 32 is one, and the elastic sheet 32 is located between the two friction plates 31.

[0051] In some embodiments, the number of elastic sheets 32 is multiple, and each elastic sheet 32 is located between adjacent two friction plates 31. In this way, all the elastic sheets 32 can be protected by the two friction plates 31, and the elastic sheets 32 provide the pressing force for the friction plate 31 and the connecting plate 11, the connecting plate 11 and the third surface 22. The multiple elastic sheets 32 can be stacked. The more the number of elastic sheets 32 is, the greater the pressing force can be provided, and the greater the rotating friction can be provided.

[0052] In some embodiments of the utility model, please refer to Figure 3 and Figure 4 , the second connecting seat 20 has the third surface 22 facing the connecting plate 11, the number of friction plates 31 is two, the third surface 22, the elastic sheet 32, one of the friction plates 31, the connecting plate 11 and the other friction plate 31 are sequentially arranged along the axial direction. The rotating shaft 21 is formed by the third surface 22 protruding, the first surface 111 of the connecting plate 11 faces the third surface 22, and the second surface 112 of the connecting plate 11 faces away from the third surface 22. The elastic sheet 32 is in a compressed state and can press the axial one end surface of one of the friction plates 31 and the first surface 111 of the connecting plate 11. When the first connecting seat 10 and the second connecting seat 20 rotate relative to each other, the first surface 111 of the first connecting seat 10 and one of the friction plates 31 contact and rotate relative to each other, and the first surface 111 and the friction plate 31 are pressed by the pressure provided by the elastic sheet 32, which can increase the rotating friction between the two; the second surface 112 of the first connecting seat 10 and the axial one end surface of the other friction plate 31 contact and rotate relative to each other, and the second surface 112 and the friction plate 31 are pressed by the pressure provided by the elastic sheet 32, which can increase the rotating friction between the two.

[0053] The opposite sides of the connecting plate 11 are provided with the friction plates 31, that is, the axial two sides of the connecting plate 11 can provide the rotating friction, so that the stable rotation between the two rotating seats is ensured. Moreover, the elastic sheet 32 is located between the third surface 22 and one of the friction plates 31, so that the elastic sheet 32 can work normally.

[0054] In some embodiments, the number of elastic sheets 32 is one. Alternatively, the number of elastic sheets 32 is multiple.

[0055] In some embodiments of the utility model, please refer to Figure 3 And Figure 4 The periphery of the third surface 22 extends in the axial direction to form an annular shielding portion 23, and the elastic sheet 32 is located in the annular shielding portion 23. The periphery of the third surface 22 is the edge of the third surface 22 extending in the circumferential direction, the annular shielding portion 23 has an annular structure, the annular shielding portion 23 encloses a disc-shaped space, and the elastic sheet 32 is located in the disc-shaped space.

[0056] Through the arrangement of the annular shielding portion 23, installation space can be provided for the elastic sheet 32, and the elastic sheet 32 can be protected.

[0057] In some embodiments, the annular shielding portion 23 extends in a direction away from the third surface 22 to shield the first friction sheet 31 (the friction sheet 31 close to the third surface 22). Alternatively, the annular shielding portion 23 extends in a direction away from the third surface 22 to shield the connecting plate 11. Alternatively, the annular shielding portion 23 extends in a direction away from the third surface 22 to shield the second friction sheet 31 (the friction sheet 31 away from the third surface 22).

[0058] In some embodiments, please refer to Figure 3 And Figure 4 The outer diameter of the annular shielding portion 23 is greater than the outer diameters of the friction sheet 31 and the connecting plate 11. That is, among the friction sheet 31, the connecting plate 11, and the annular shielding portion 23, the outer diameter of the annular shielding portion 23 is the largest. Since the elastic sheet 32 is located inside the annular shielding portion 23, the outer diameter of the elastic sheet 32 is smaller than the inner diameter of the annular shielding portion 23.

[0059] Since the outer diameter of the annular shielding portion 23 is greater than the outer diameters of the friction sheet 31 and the connecting plate 11, a space is formed at the outer periphery of the friction sheet 31 and the connecting plate 11, which reduces the space occupied by the rotating connection structure as much as possible, and provides space for the main body.

[0060] Optionally, the outer diameters of the two friction sheets 31 and the outer diameter of the connecting plate 11 are the same, so that the outer contour of the rotating connection structure is more regular. In other embodiments, the outer diameters of the two friction sheets 31 and the outer diameter of the connecting plate 11 can be different.

[0061] In some embodiments of the utility model, please refer to Figure 3, the end of the rotating shaft 21 away from the third surface 22 is a press riveting structure 211, and the friction plate 31 adjacent to the press riveting structure 211 is axially limited by the press riveting structure 211.

[0062] Specifically, as Figure 4 and Figures 1 to 4 In the assembly of the first connecting seat 10 and the second connecting seat 20, the connecting plate 11 of the first connecting seat 10 is first installed on the rotating shaft 21 of the first connecting seat 10, then the first friction plate 31, the elastic sheet 32 and the second friction plate 31 are sequentially installed on the rotating shaft 21, and finally the end of the rotating shaft 21 away from the third surface 22 is press riveted to form the press riveting structure 211. Figure 1 and Figure 2 Figure 3 Figure 4 In the assembly of the first connecting seat 10 and the second connecting seat 20, the elastic sheet 32 and the first friction plate 31 are first installed on the rotating shaft 21, then the connecting plate 11 of the first connecting seat 10 is installed on the rotating shaft 21, then the second friction plate 31 is installed on the rotating shaft 21, and finally the end of the rotating shaft 21 away from the third surface 22 is press riveted to form the press riveting structure 211.

[0063] By press riveting the end of the rotating shaft 21 away from the third surface 22 to form the press riveting structure 211, the connecting plate 11, the elastic sheet 32 and the friction plate 31 can be axially limited, and the forming process of the press riveting structure 211 is simple and does not occupy additional space.

[0064] In some embodiments of the utility model, the elastic sheet 32 is a steel sheet.

[0065] Optionally, the elastic sheet 32 is a disc spring.
