[0075] The following will describe in detail various embodiments of the present invention, and will be illustrated with the accompanying drawings. In addition to these detailed descriptions, the present invention can also be widely implemented in other embodiments, and any easy replacement, modification, and equivalent changes of the embodiments are included in the scope of the present invention and are subject to the scope of the patent of the present invention. In the description of the specification, in order to give the reader a more complete understanding of the present invention, many specific details and embodiments are provided; however, these specific details and embodiments should not be regarded as limitations of the present invention. In addition, well-known steps or elements are not described in detail to avoid unnecessary limitations of the present invention. In the drawings, the same or similar element symbols are used to represent the same or similar elements.

[0076] Figure 1 is an assembly diagram of a coaxial rotating structure 100 according to an embodiment of the present invention; Figure 2A It is drawn from the first person perspective Figure 1 An exploded view of the coaxial rotating structure 100; Figure 2B It is drawn from a second perspective Figure 1 Exploded view of the coaxial rotating structure 100.

[0077] Please refer to Figure 1 , Figure 2A and Figure 2B The coaxial rotating structure 100 at least includes a base 110, a first rotating member 120, a second rotating member 130, a first elastic movable member 140, a second elastic movable member 150 and a locking member 160. The first rotating member 120 and the second rotating member 130 are disposed on the base 110, the second rotating member 130 is disposed in the first rotating member 120, and the first rotating member 120 and the second rotating member 130 have the same rotation axis R. In one embodiment, the coaxial rotating structure 100 may further include a decorative member DR. The decorative member DR may be covered on the second rotating member 130 via an adhesive member AH.

[0078] The base 110 may include a body 111. The locking member 160 is disposed on the base 110 and can move between a stop position and a release position. In a specific embodiment, the coaxial rotating structure 100 may further include an elastic member 170, which may be disposed between the base 110 and the locking member 160, so that the locking member 160 can move in the Y-axis direction substantially parallel to the rotation axis R. When the coaxial rotating structure 100 is in the stop state, the spring member 170 is in a free state without load, and the locking member 160 is located in the stop position; when the locking member 160 is subjected to an external force and moves toward the negative direction of the Y axis, the spring member 170 will store elastic potential energy due to compression, wherein the maximum displacement of the locking member 160 can reach the release position, and at this time the coaxial rotating structure 100 is in the release state; once the locking member 160 is no longer subjected to force, the spring member 170 can release the stored elastic potential energy, push the locking member 160 to move toward the positive direction of the Y axis, and return to the stop position. The locking member 160 may include a pressing portion 161, and the locking member 160 may receive external force through the pressing portion 161; the locking member 160 may also include a hook portion 162, and the hook portion 162 may be disposed in a buckle through hole 111H1 of the base 110, and the buckle through hole 111H1 penetrates the body 111 of the base 111. The hook portion 162 and the buckle through hole 111H1 prevent the locking member 160 from falling off the base 110 during the process of returning to the stop position via the spring member 170.

[0079] Figure 3 yes Figure 2A A schematic diagram of the second rotating member 130; Figure 4 Schematic diagram of the locking member 160 being located at the stop position.

[0080] Please refer to Figure 2B , Figure 3 and Figure 4 , the locking member 160 may further include a stopper 163. The stopper 163 extends toward the positive direction of the Y-axis. The second rotating member 130 may include a turntable body 131, and the turntable body 131 may have a first surface 131S1 and a second surface 131S2 in the negative Y-axis direction. The first surface 131S1 and the second surface 131S2 are surfaces that are perpendicular to the Y-axis and have a distance difference on the Y-axis. In other words, a recessed area (not shown) may be formed from the first surface 131S1 of the turntable body 131 to the second surface 131S2 toward the Y-axis, and a plurality of recesses 131R may be formed on the periphery of the recessed area, and these recesses 131R may be arranged equidistantly along the circumference of the second rotating member 130, wherein the shapes of these recesses 131R may correspond to the stopper 163 of the locking member 160.

[0081] like Figure 4As shown, in a specific embodiment, when the locking member 160 is located at the stop position, the stop portion 163 can be located in one of the recesses 131R, so that the second rotating member 130 is locked by the locking member 160 and cannot rotate on the rotating shaft R; when the locking member 160 is located at the release position, the stop portion 163 exits the recess 131R, and the second rotating member 130 can rotate on the rotating shaft R at this time.

[0082] When the locking member 160 is located at the stop position, although the second rotating member 130 cannot rotate on the rotation axis R, the first rotating member 120 can still rotate relative to the second rotating member 130 on the rotation axis R. In addition, when the first rotating member 120 rotates relative to the second rotating member 130 on the rotation axis R, the first elastic movable member 140 can provide a tactile feedback of a stepping sense.

[0083] Figure 5 yes Figure 2A A schematic diagram of the first rotating member 120; Figure 6 Shown from another perspective Figure 3 A schematic diagram of the second rotating member 130; Figure 7 is a schematic diagram of assembling the first elastic movable member 140 and the second elastic movable member 150; Figure 8 yes Figure 1 An assembly diagram of some components of the coaxial rotating structure 100.

[0084] Please refer to Figure 5 , the first rotating member 120 may include an annular body 121 and an operating portion 122. The operating portion 122 is formed on the outer circumferential surface 121S1 of the annular body 121 and can be rotated and operated by a user. The first rotating member 120 may have a plurality of first positioning grooves 121R, which may be recessed in the inner ring surface 121S2 of the annular body 121 and may be arranged equidistantly along the circumference of the first rotating member 120. In one embodiment, the first positioning groove 121R has an open end on one side of the positive direction of the Y axis.

[0085] Please refer to Figure 3 and Figure 6 , the second rotating member 130 may have a first groove 131R1 and a second groove 131R2. The turntable body 131 may also have a third surface 131S3 and an outer peripheral surface 131S4 in the positive Y-axis direction, and the third surface 131S3 is perpendicular to the Y-axis, and the outer peripheral surface 131S4 connects the first surface 131S1 and the third surface 131S3. The first groove 131R1 may be recessed from the third surface 131S3 of the turntable body 131 to the negative Y-axis direction, and the second groove 131R2 may be recessed from the outer peripheral surface 131S4 of the turntable body 131 to the rotation axis R direction, and the first groove 131R1 and the second groove 131R2 intersect each other.

[0086] Please refer to Figure 5 , Figure 6 and Figure 7 , the first elastic movable member 140 is disposed between the first rotating member 120 and the second rotating member 130. The first elastic movable member 140 can be disposed parallel to the radial direction of the second rotating member 130 (that is, in any direction on the XZ plane). The first elastic movable member 140 can be disposed on the second rotating member 130 by means of the first groove 131R1. In a specific embodiment, the first elastic movable member 140 may include a first elastic member 141 and a first engaging member 142. The first elastic member 141 may include a compression spring, one end of which is connected to the turntable body 131 of the second rotating member 130, and the other end is connected to the first engaging member 142. When the first elastic movable member 140 is inserted into the second rotating member 130, the first engaging member 142 may be exposed from the second groove 131R2 and abut against one of the first positioning grooves 121R of the first rotating member 120. When the locking member 160 is at the stop position, the user can rotate the operating portion 122 to allow the first rotating member 120 to rotate relative to the second rotating member 130 on the rotation axis R, that is, in the stop state, the first rotating member 120 can rotate while the second rotating member 130 cannot rotate. During the rotation of the first rotating member 120, the annular body 121 can generate a force to push the first engaging member 142 to move radially toward the rotation axis R, so that the first elastic member 141 is compressed; and when the first rotating member 120 continues to rotate, the first engaging member 142 is in contact with the next adjacent first positioning groove 121R, and the first engaging member 142 can be abutted against the next adjacent first positioning groove 121R by the restoring force of the first elastic member 141. Therefore, the first engaging member 142 can sequentially cross these first positioning grooves 121R, thereby generating a tactile feedback of a sense of segmentation.

[0087] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 When the locking member 160 moves toward the negative Y axis to the release position, the stopper 163 of the locking member 160 exits the recess 131R, and the second rotating member 130 can rotate together with the first rotating member 120 on the rotation axis R. In actual operation, the user can press the pressing portion 161 with one finger (such as the index finger) and rotate the operating portion 122 of the first rotating member 120 with another finger (such as the thumb), so that the first rotating member 120 and the second rotating member 130 rotate on the rotation axis R at the same time.

[0088] Here, the second rotating member 130 can rotate synchronously with the first rotating member 120 through the first elastic movable member 140. In addition, when the user rotates the first rotating member 120 to make the first rotating member 120 and the second rotating member 130 rotate simultaneously, the second elastic movable member 150 can also provide a step-feeling tactile feedback to the user.

[0089] Please refer to Figure 3 and Figure 6 The second rotating member 130 may further include a through portion 131H1. The through portion 131H1 may penetrate the second surface 131S2 and the third surface 131S3 of the turntable body 131 along the Y axis.

[0090] Please refer to Figure 3 and Figure 8 The body portion 111 of the base 110 has a joint surface 111S1, which faces the positive direction of the Y axis. The second surface 131S2 of the turntable body 131 of the second rotating member 130 can be connected to the joint surface 111S1. The base 110 can also have a plurality of second positioning grooves 111R, which can be recessed from the joint surface 111S1 toward the negative Y axis direction. The through portion 131H1 of the second rotating member 130 can correspond to these second positioning grooves 111R.

[0091] Please refer to Figure 2A , Figure 7 and Figure 8 , the second elastic movable member 150 is disposed between the second rotating member 130 and the base 110, the second elastic movable member 150 can be disposed parallel to the rotation axis R (i.e., parallel to the Y axis), and the second elastic movable member 150 can move in the direction of the Y axis. Specifically, the second elastic movable member 150 can be inserted into the second rotating member 130 through the through portion 131H1. In a specific embodiment, the second elastic movable member 150 may include a second elastic member 151 and a second engaging member 152. The second elastic member 151 may include a compression spring, one end of which is connected to the decorative member DR, and the other end of which is connected to the second engaging member 152.

[0092] Also refer to Figure 2A , Figure 4 , Figure 7 and Figure 8 When the second elastic movable member 150 is inserted into the second rotating member 130, the second engaging member 152 can be exposed from the second surface 131S2 of the turntable body 131 of the second rotating member 130 and abut against one of the second positioning grooves 111R of the base 110. Since the elastic coefficient of the first elastic member 141 of the first elastic movable member 140 is greater than the elastic coefficient of the second elastic member 151 of the second elastic movable member 150, when the locking member 160 is located at the release position and the first rotating member 120 rotates, since the first elastic member 141 has a higher ability to resist deformation than the second elastic member 151, the first engaging member 142 can still abut against the first positioning groove 121R firmly and drive the second rotating member 130 and the first rotating member 120 to rotate synchronously on the rotating shaft R.

[0093] During the synchronous rotation of the second rotating member 130 and the first rotating member 120, the main body 111 of the base 110 can generate a force to push the second embedded member 152 to move along the Y axis, so that the second elastic member 151 is compressed; and when the first rotating member 120 and the second rotating member 130 continue to rotate, so that the second embedded member 152 and the next adjacent second positioning groove 111R are correspondingly connected and separated, the second embedded member 152 can be abutted against the next adjacent second positioning groove 111R by the restoring force of the second elastic member 151. Therefore, the second embedded member 152 can sequentially cross these second positioning grooves 111R, thereby generating a tactile feedback of a sense of segmentation.

[0094] Please refer to Figure 2A , Figure 2B , the base 110 may also have an axial hole 111H2 penetrating the main body 111. In one embodiment, the coaxial rotating structure 100 may also include a signal sensing module 180 and a rotating contact member 190. The signal sensing module 180 may include a circuit board 181 and a plurality of pads 181P and a light sensor 182 disposed on the circuit board 181. The rotating contact member 190 may include a contact member 191 and a rotating base 192. The contact member 191 may be first fixed on the rotating base 192. Next, the elastic member 170, the locking member 160, the first rotating member 120 and the second rotating member 130 are sequentially disposed on the main body 111 of the base 110. On the other hand, the rotating contact member 190 is disposed on the main body 111 of the base 110. At this time, the shaft portion 132 of the second rotating member 130 is inserted into the axial hole 111H2 of the base 110 and the positioning hole 192H of the rotating base 192. Then, the fixing element F1 is used to pass through the contact element 191 and the rotating base 192 in sequence to fix the rotating contact element 190 to the second rotating element 130. After that, the signal sensing module 180 is fixed to the base 110 by the fixing element F2.

[0095] Please refer to Figure 2A , Figure 2B and Figure 4 , the first rotating member 120 may further include a light sensing stripe structure 123 formed on one side of the annular body 121 close to the negative direction of the Y axis. The light sensing stripe structure 123 may include sensing stripes 123a and 123b that alternate between light and dark. The base 110 may further include a light sensing through hole 111H3, which passes through the main body 111 of the base 110. The light sensor 182 may include a first light sensing unit 182a and a second light sensing unit 182b. The first light sensing unit 182a and the second light sensing unit 182b may sense changes in the sensing stripes 123a and 123b through the first hole 111H3a and the second hole 111H3b of the light sensing through hole 111H3, respectively, so that the signal sensing module 180 may sense the first operation signal.

[0096] Please refer to Figure 2A and Figure 2B The contact member 191 may include an elastic contact portion 191P. The elastic contact portion 191P may contact a corresponding pad 181P on the circuit board 181, so that the signal sensing module 180 may sense the second operation signal.

[0097] Fig. 9 yes Figure 1 The cross-sectional view of the coaxial rotating structure 100 along the section line AA' shows that the locking member 160 is located at the stop position; Fig. 10A yes Figure 1 A cross-sectional view of the coaxial rotating structure 100 along the section line AA' shows that the locking member 160 is located in the release position; Fig. 10B yes Figure 1 The cross-sectional view of the coaxial rotating structure 100 along the section line BB′ shows that the locking element 160 is located at the release position.

[0098] Please refer to Figure 2A and Fig. 9 When the locking member 160 is located at the stop position, the stop portion 163 is located in the recess 131R. At this time, the user can rotate the first rotating member 120, and the second rotating member 130 cannot rotate about the rotation axis R through the stop portion 163 and the recess 131R, and the user can feel the tactile feedback of the segment sense through the first elastic movable member 140. When the first rotating member 120 rotates, the first light sensing unit 182a and the second light sensing unit 182b can sense the changes of the sensing stripes 123a and 123b, for example, sensing whether the rotation direction of the first rotating member 120 is clockwise or counterclockwise, thereby sensing the first operation signal.

[0099] Please refer to Figure 2A , Fig. 10A and Fig. 10B When the locking member 160 is in the release position, the stopper 163 exits the recess 131R. At this time, the user can rotate the first rotating member 120, and the second rotating member 130 rotates synchronously with the first rotating member 120 through the first elastic movable member 140, and the user can feel the tactile feedback of the segment sense through the second elastic movable member 150. Since the rotating contact member 190 is fixed to the second rotating member 130, when the second rotating member 130 rotates on the rotating shaft R, the contact member 191 and the rotating base 192 also rotate together, so that the elastic contact portion 191P contacts different pads 181P on the circuit board 181, thereby sensing the second operation signal.

[0100] In one embodiment, the signal sensing module 180 may further include a control module (not shown). The control module may sense the first operation signal or the second operation signal and execute a corresponding function according to the first operation signal or the second operation signal.

[0101] Although the present invention has been described above with reference to the embodiments, it is not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the attached patent application.
