Description

Technical Field

[0001] This invention relates to a rotating structure, and more particularly to a rotating structure that provides stable rotational control and smooth damping feedback. Background Technology

[0002] Rotary mechanical operating mechanisms are widely used in everyday products. These mechanisms not only need to ensure stable rotational stroke but also provide tactile feedback to enhance the user experience. Therefore, diversifying the tactile feedback of rotary mechanisms to improve the user experience is particularly important. Summary of the Invention

[0003] This utility model relates to a rotating structure, which provides stable rotational control and smooth damping feedback by setting a layered structure between the rotating component and the fixed component.

[0004] This utility model proposes a rotating structure, including a fixed member, a rotating member, and a layered structure. The fixed member is sleeved inside the rotating member, and the rotating member and the fixed member are rotatable relative to each other on a rotating shaft. The layered structure is disposed between the fixed member and the rotating member, and the layered structure includes an elastic compression layer and a guide layer in sequence from the fixed member to the rotating member.

[0010] The following details various embodiments of this utility model, illustrated in the accompanying drawings. Besides these detailed descriptions, this utility model can be widely implemented in other embodiments. Any easy substitutions, modifications, or equivalent changes to the described embodiments are included within the scope of this utility model and are subject to the claims. In the description of this specification, many specific details and implementation examples are provided to give the reader a more complete understanding of this utility model; however, these specific details and implementation examples should not be considered as limitations of this utility model. Furthermore, well-known steps or components are not described in the details to avoid unnecessary limitations on this utility model.

[0011] Figure 1 This is a perspective view of a rotating structure 100 according to an embodiment of the present invention; Figure 2 yes Figure 1 Exploded view of the rotating structure 100.

[0012] Reference Figure 1 and Figure 2 The rotating structure 100 includes at least a fixing member 110, a rotating member 120, and a layered structure 130. The fixing member 110 is sleeved inside the rotating member 120, and the fixing member 110 and the rotating member 120 can rotate relative to each other on the rotating shaft S. The layered structure 130 is disposed between the fixing member 110 and the rotating member 120.

[0013] like Figure 2 As shown, the laminated structure 130 can be arranged in a ring around the pivot S and attached to the surface 110a of the fastener 110. Figure 2 The layered structure 130 shown is a strip structure that directly surrounds the pivot S to form a ring structure; in other embodiments, the layered structure 130 may also be a multi-segment strip structure, and these strip structures are attached to the surface 110a of the fastener 110 around the pivot S, that is, the layered structure 130 may include multiple arc strips, and two adjacent arc strips may be connected, not connected, or arranged at equal intervals.

[0014] Figure 3 It is along Figure 1 A partial sectional view showing the section line 3-3'; Figure 4 yes Figure 3 A magnified view of a local region R in the image.

[0015] Reference Figure 3 and Figure 4The laminated structure 130 is sandwiched between the surface 110a of the fixing member 110 and the surface 120a of the rotating member 120. From the fixing member 110 to the rotating member 120, the laminated structure 130 sequentially includes at least an elastic compression layer 131 and a guide layer 132. That is, from the direction near the rotation axis S to the direction away from the rotation axis S, the elastic compression layer 131 and the guide layer 132 are sequentially stacked on top of each other along a stacking direction parallel to the XY plane. (Refer to...) Figure 1 and Figure 4 The stacking direction of the stacked structure 130 is a radial direction with the rotation axis S as the center. Therefore, the stacking direction is perpendicular to the rotation axis S extending in the Z-axis direction.

[0016] Reference Figure 4 The elastic compression layer 131 of the laminated structure 130 is disposed facing the fastener 110. The elastic compression layer 131 is a compressible body that is elastic in the stacking direction. In one embodiment, the elastic compression layer 131 may be a rubber compression layer, a foam compression layer, or a silicone compression layer. For example, the elastic compression layer 131 may be made of, but is not limited to, natural rubber, synthetic rubber, PU foam, PE foam, EPDM foam, EVA foam, PP foam, silicone, or a mixture or combination of the above materials.

[0017] Reference Figure 4 The guide layer 132 of the laminated structure 130 is disposed facing the rotating member 120. The guide layer 132 may include a self-lubricating material and can directly contact the rotating member 120. When the rotating member 120 rotates relative to the fixed member 110, the self-lubricating properties of the guide layer 132 reduce friction with the rotating member 120, making the rotation of the rotating member 120 easier and smoother. In a specific embodiment, the guide layer 132 may be a Teflon guide layer, which may be a Teflon-coated fabric.

[0018] During the rotation of the rotating component 120, the compressive restoring force generated by the elastic compression layer 131 in the stacking direction can provide stable friction, allowing the user to feel stable force feedback and rotation control during operation.

[0019] In one embodiment, the rotating member 120 can be a plastic rotating member, meaning the material of the rotating member 120 can be plastic. In this case, the compressive restoring force generated by the elastic compression layer 131 in the stacking direction can also compensate for the shortcomings of insufficient processing precision of the plastic part. Therefore, the rotating structure of this invention can still provide stable rotational control and smooth damping feedback even under conditions of lower manufacturing precision.

[0020] Reference Figure 4The laminated structure 130 may further include a first adhesive layer 133 and a second adhesive layer 134. In one embodiment, the first adhesive layer 133 and the second adhesive layer 134 may be double-sided adhesive. The first adhesive layer 133 is disposed between the elastic compression layer 131 and the fastener 110, and the second adhesive layer 134 is disposed between the elastic compression layer 131 and the guide layer 132, so as to improve the bonding effect between the laminated structures 130 and between the laminated structure 130 and the fastener 110.

[0021] Reference Figure 4 The dashed area shown represents the structure of the laminated structure 130 before compression, which has a first thickness T1. A preset distance is initially designed between the rotating member 120 and the fixing member 110, and this preset distance is less than the first thickness T1. When the laminated structure 130 is positioned between the rotating member 120 and the fixing member 110, it is compressed, resulting in a second thickness T2 after compression. This second thickness T2 is substantially equal to the preset distance between the rotating member 120 and the fixing member 110.

[0022] The compression ratio of the laminate 130 can be a percentage of the ratio of the compressed thickness to the uncompressed thickness. The compression ratio of the laminate 130 can be defined as follows:

[0023]

[0024] In one embodiment, the compression ratio of the stacked structure 130 may be 10%. In a specific embodiment, the stacked structure 130 has an uncompressed first thickness T1 of approximately 0.7 mm and a compressed second thickness T2 of approximately 0.63 mm. Therefore, when the user operates the rotating member 120 to rotate, the stacked structure 130 can provide stable friction in the stacking direction.

[0025] In summary, although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
