Detailed Description

The invention provides a rotating device, in particular to a rotating device which realizes large-angle limiting and increases bidirectional limiting angle and bidirectional rotating number through a movable ring. Specifically, the rotating device of the present invention can be applied to any device requiring a large angle limitation and increasing the bidirectional limitation angle and the number of bidirectional rotation turns, such as a display device, but not limited thereto. Hereinafter, details of the rotating apparatus according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1A and 1B, in one embodiment, the rotating device 1 of the present invention includes a rotatable member 10, at least one movable ring 20, and a supporting member 30. In this embodiment, a movable ring 20 is taken as an example for illustration, but not limited thereto. The rotatable member 10 includes a rotating ring 11 and a positioning portion 12, and the positioning portion 112 axially protrudes from the peripheral edge of the rotating ring 11. The movable ring 20 has an acting portion 22. The support 30 has a stopper 32. The rotating ring 11 and the movable ring 20 are coaxially disposed on the support 30, and the movable ring 20 is disposed between the rotatable member 10 and the support 30. The rotating ring 11 and the movable ring 20 can rotate relative to the supporting member 30, a portion of the positioning portion 12 overlaps the movable ring 20, and when the rotating ring 11 rotates relative to the supporting member 30, the portion of the positioning portion 12 pushes against the acting portion 22, so as to drive the movable ring 20 to rotate until the acting portion 22 is stopped between the positioning portion 12 and the stopping portion 32.

For example, the positioning portion 12 may be a convex pillar or a convex bump extending radially from the rotating ring 11 and axially beyond the bottom surface of the rotating ring 11, and the length of the portion of the positioning portion 12 protruding from the bottom surface of the rotating ring 11 preferably does not exceed the thickness (i.e., axial height) of the movable ring 20 when overlapping with the movable ring 20, so as to avoid interference with the component below the movable ring 20.

Specifically, the rotatable member 10 may be implemented as any convenient rotating element and may be used to connect to other devices to provide the function of enabling the other devices to rotate, such as a display device, after the rotatable member 10 is connected to the other devices, the other devices may be rotated by the external force applied by the user or by the power provided by other power devices.

In one embodiment, the movable ring 20 includes a ring body 21, and the active portion 22 includes an upper portion 222 and a lower portion 224. The upper portion 222 protrudes from the periphery of the ring main body 21, and the lower portion 224 axially protrudes from one end of the upper portion 222 from the ring main body 21. For example, the acting portion 22 may be a convex pillar or a convex block extending radially from the ring main body 21 and axially extending beyond the bottom surface of the ring main body 21, wherein a portion of the convex pillar or the convex block connected with the ring main body 21 may be regarded as an upper portion 222 of the acting portion 22, and a portion of the convex pillar or the convex block axially protruding from the ring main body 21 may be regarded as a lower portion 224 of the acting portion 22. In this embodiment, the movable ring 20 has the same structure as the rotatable member 10, but is not limited thereto. The axial thickness of the ring main body 21, the width of the acting portion 22 in the circumferential direction of the ring main body 21, and the like may vary depending on the actual application.

In this embodiment, the supporting member 30 includes a supporting shaft 31, and the stopping portion 32 is fixed on the supporting shaft 31. For example, the stopping portion 32 may be a convex pillar or a bump extending and protruding from the supporting shaft 31 in the radial direction. The diameter of the support shaft 31 is preferably slightly smaller than the ring diameter of the ring body 21 and the rotating ring 11, so that the ring body 21 and the rotating ring 11 can rotate relative to the support shaft 31 when they are sleeved on the support shaft 31.

As shown in fig. 1B, when the rotatable member 10 and the movable ring 20 are sleeved on the supporting shaft 31, the positioning portion 12 axially protrudes from the rotating ring 11 and preferably overlaps the ring main body 21 of the movable ring 20, thereby effectively reducing the axial height (or thickness) of the rotating device. Furthermore, the positioning portion 12 and the acting portion 22 are partially overlapped in the circumferential direction (or the rotational direction), and the positioning portion 12 does not protrude from the bottom surface of the ring main body 21. Specifically, the positioning portion 12 corresponds to the upper portion 222 of the acting portion 22 in the circumferential direction (or the rotational direction) so that the portion of the positioning portion 12 can be pushed against the upper portion 222, and the positioning portion 12 preferably does not correspond to the lower portion 224 of the acting portion 22 and does not interfere with the stopper 32 below the movable ring 20. Furthermore, the acting portion 22 partially corresponds to the stopping portion 32, for example, the stopping portion 32 corresponds to the lower portion 224 of the acting portion 22 along the rotation direction, so that the stopping portion 32 can stop the lower portion 224.

The following description will explain the bidirectional positioning operation of the rotating apparatus 1 of the present invention, for example, about ± 360 degrees. As shown in fig. 2A and 2B, in one embodiment, the movable ring 20 is preferably disposed such that the acting portions 22 and the stopping portions 32 are staggered left and right along the virtual line L parallel to the axial direction. For example, the movable ring 20 can be disposed such that the acting portion 22 is located in the counterclockwise direction of the stopping portion 32 (i.e. on the right side of the virtual line L), and the positioning portion 12 of the rotatable element 10 is also preferably disposed along the virtual line L on the same side as the stopping portion 32, i.e. on the left side of the virtual line L. Therefore, when the rotatable element 10 rotates, the portion of the positioning portion 12 pushes against the acting portion 22, and the movable ring 20 is driven to rotate until the acting portion 22 is stopped between the positioning portion 12 and the stopping portion 32 (the dotted line shows the position of rotational positioning). Specifically, as shown in fig. 2A, when the rotatable element 10 rotates about 360 degrees in the first rotation direction R1 (e.g., clockwise), the portion of the positioning portion 12 of the rotatable element 10 abuts against the upper portion 222 of the acting portion 22 and pushes against the upper portion 222 of the acting portion 22 to drive the ring main body 21 to rotate until the lower portion 224 of the acting portion 22 contacts the stopping portion 32, so that the acting portion 22 is stopped between the positioning portion 12 and the stopping portion 32. That is, the right side of the acting portion 22 abuts against the positioning portion 12, and the left side of the acting portion 22 abuts against the stopper portion 32, so that the clockwise positioning of the rotatable member 10 is realized by about 360 degrees. Furthermore, as shown in fig. 2B, when the rotatable element 10 rotates about 360 degrees in a second rotation direction R2 (e.g., counterclockwise) opposite to the first rotation direction R1, the lower portion of the positioning portion 12 of the rotatable element 10 abuts against the upper portion 222 of the acting portion 22 and pushes against the upper portion 222 of the acting portion 22 to rotate the ring main body 21 until the lower portion 224 of the acting portion 22 abuts against the stopping portion 32, so that the acting portion 22 is stopped between the positioning portion 12 and the stopping portion 32. That is, the left side of the acting portion 22 abuts against the positioning portion 12, and the right side of the acting portion 22 abuts against the stopper portion 32, so that the rotatable member 10 is positioned counterclockwise by about 360 degrees.

It should be noted that, although the above embodiment is described by taking a bidirectional positioning of about ± 360 degrees as an example, the invention is not limited thereto. The rotating device can realize the bidirectional positioning of different limiting angles by adjusting the number and the positions of the stopping parts. For example, as shown in fig. 3A and 3B, in this embodiment, the supporting member 30 preferably has two stopping portions (e.g., a first stopping portion 32a and a second stopping portion 32B). The two stopping portions 32a, 32b are disposed at the periphery of the supporting shaft 31 and preferably are separated by 180 degrees, so as to achieve bidirectional positioning of about ± 270 degrees, for example. Specifically, the rotatable member 10 is preferably arranged such that the positioning portion 12 is located between the two stopping portions 32a and 32b, i.e., the positioning portion 12 is 90 degrees different from the first stopping portion 32a and the second stopping portion 32b, and the movable ring 20 is preferably arranged such that the acting portion 22 is located on the opposite side of the positioning portion 12. In other words, the acting part 22 of the movable ring 20 is preferably located between the two stopping parts 32a and 32b, and the acting part 22 of the movable ring 20 is preferably located on a different side from the positioning part 12 with respect to a connecting line of the two stopping parts 32a and 32 b.

The following describes the bi-directional positioning operation of the rotating device of the present embodiment, for example, about ± 270 degrees. Specifically, as shown in fig. 3A, when the rotatable element 10 rotates in a first rotation direction R1 (e.g., clockwise) relative to the supporting element 30, the portion of the positioning portion 12 pushes against the acting portion 22, and the movable ring 20 is driven to rotate until the acting portion 22 is stopped between the positioning portion 12 and the first stopping portion 33A, where the positioning position is shown by a dotted line. Specifically, when the rotatable element 10 rotates about 270 degrees along the first rotation direction R1 (e.g., clockwise) relative to the supporting shaft 31, the positioning portion 12 of the rotatable element 10 first passes through the second stopping portion 32b, and then the portion of the positioning portion 12 abuts against the upper portion of the acting portion 22 and pushes against the upper portion of the acting portion 22 to rotate the ring main body 21 until the lower portion of the acting portion 22 contacts the first stopping portion 32a, so that the acting portion 22 is stopped between the positioning portion 12 and the first stopping portion 32a, and the rotatable element 10 is positioned about 270 degrees clockwise. Furthermore, as shown in fig. 3B, when the rotatable element 10 rotates relative to the supporting element 30 in a second rotation direction R2 (e.g., a reverse direction) opposite to the first rotation direction R1, the portion of the positioning portion 12 pushes against the acting portion 22, and the movable ring 20 is driven to rotate until the acting portion 22 is stopped between the positioning portion 12 and the second stopping portion 32B, where the positioning position is shown by a dotted line. Specifically, when the rotatable element 10 rotates about 270 degrees along the second rotation direction R2 (e.g., counterclockwise) relative to the supporting shaft 31, the positioning portion 12 of the rotatable element 10 first passes through the first stopping portion 32a, and then the portion of the positioning portion 12 abuts against the upper portion of the acting portion 22 and pushes against the upper portion of the acting portion 22 to rotate the ring main body 21 until the lower portion of the acting portion 22 contacts the second stopping portion 32b, so that the acting portion 22 is stopped between the positioning portion 12 and the second stopping portion 32b, and the rotatable element 10 is positioned about 270 degrees counterclockwise.

Furthermore, the rotating device of the present invention can realize the bidirectional positioning at different limiting angles by adjusting the number and the positions of the positioning portions 22. For example, as shown in fig. 4A and 4B, in this embodiment, the movable ring 20 preferably has two acting portions (e.g., the first acting portion 22 and the second acting portion 24), and the two acting portions 22 and 24 are preferably separated by 90 degrees, so as to achieve a bidirectional positioning of about 270 degrees, for example. Specifically, the rotatable member 10 and the movable ring 20 are preferably arranged relative to the stopping portion 32 in a similar configuration as shown in fig. 2A, for example, the positioning portion 12, the first acting portion 22 and the stopping portion 32 are staggered left and right along a virtual line L parallel to the axial direction, and the second acting portion 24 and the first acting portion 22 are located on the same side of the virtual line L and are different by 90 degrees. The following describes the bi-directional positioning operation of the rotating device of the present embodiment, for example, about ± 270 degrees. Specifically, as shown in fig. 4A, when the rotatable element 10 rotates in the first rotation direction R1 (e.g., clockwise) relative to the supporting element 30, the portion of the positioning portion 12 pushes against the second acting portion 24, and the movable ring 20 is driven to rotate until the second acting portion 24 and the first acting portion 22 are stopped between the positioning portion 12 and the stopping portion 32. Specifically, when the rotatable element 10 rotates about 270 degrees along the first rotation direction R1 (e.g., clockwise) relative to the supporting shaft 31, the portion of the positioning portion 12 of the rotatable element 10 first abuts against the upper portion 242 of the second acting portion 24 and pushes against the upper portion 242 of the second acting portion 242 to drive the ring main body 21 to rotate until the lower portion 224 of the first acting portion 22 contacts the stopping portion 32, so that the second acting portion 24 and the first acting portion 22 are stopped between the positioning portion 12 and the stopping portion 32, and the rotatable element 10 is positioned about 270 degrees clockwise. Furthermore, as shown in fig. 4B, when the rotatable element 10 rotates in a second rotation direction R2 (e.g., counterclockwise) opposite to the first rotation direction R1 relative to the supporting element 30, the portion of the positioning portion 12 pushes against the first acting portion 22, and the movable ring 20 is driven to rotate until the first acting portion 22 and the second acting portion 24 are stopped between the positioning portion 12 and the stopping portion 32. Specifically, when the rotary member 10 rotates about 270 degrees in a second rotation direction R2 (e.g., counterclockwise) opposite to the first rotation direction R1 relative to the support shaft 31, the portion of the positioning portion 12 of the rotary member 10 first abuts against the upper portion 222 of the first acting portion 22 and pushes against the upper portion 222 of the first acting portion 22 to drive the ring main body 21 to rotate until the lower portion 244 of the second acting portion 24 abuts against the stopping portion 32, so that the first acting portion 22 and the second acting portion 24 are stopped between the positioning portion 12 and the stopping portion 32, and the counterclockwise positioning of the rotary member 10 is about 270 degrees.

Furthermore, the rotating device of the present invention can change the angle of the bidirectional positioning by increasing the number of the movable rings 20, and the bidirectional limiting angle can be increased by ± 180 degrees every time one movable ring is added. As shown in fig. 5A and 5B, in another embodiment, the rotating device 2 includes, for example, two movable rings 20a and 20B, wherein the movable rings 20a and 20B have the same structure as the movable ring 20 of the embodiment of fig. 1A, for example, each of the movable rings includes a ring main body 21A and 21B and an acting portion 22a and 22B, the acting portion 22a and 22B includes an upper portion 222a and 222B and a lower portion 224a and 224B, the upper portion 222a and 222B is protruded from the periphery of the ring main body 21A and 21B, and the lower portion 224a and 224B is protruded from one end of the upper portion 222a and 222B in the axial direction of the ring main body 21A and 21B. The details of the movable rings 20a and 20b can be found in the description of the movable ring 20 in fig. 1A, and are not repeated herein. In this embodiment, the two movable rings 20a and 20b are coaxially and movably disposed between the rotatable element 10 and the supporting member 30, and the upper portion 222b of the movable ring 20b close to the positioning portion 12 corresponds to the positioning portion 12, so that the portion of the positioning portion 12 can push against the upper portion 222b, and the lower portion 224a of the movable ring 20a close to the stopping portion 32 corresponds to the stopping portion 32, so that the stopping portion 32 can stop the lower portion 224 a. Specifically, when a plurality of movable rings (e.g., 20a, 20b) are coaxially arranged, the ring main bodies (e.g., 21a, 21b) thereof may be stacked on each other, and the action portion 22b of the upper movable ring (e.g., 20b) axially protrudes from the ring main body 21b thereof and overlaps the ring main body 21a of the lower movable ring 20a, and corresponds to the action portion 22a of the lower movable ring 20a in an overlapping manner in the rotational direction. In other words, the lower portion 224b of the action portion 22b of the upper movable ring 20b corresponds to the upper portion 222a of the action portion 22a of the lower movable ring 20 a. Further, like the embodiment of fig. 1A, the upper portion of the action portion of the movable ring (e.g., the uppermost movable ring 20b) closest to the rotatable member 10 corresponds to the lower portion of the positioning portion 12, and the lower portion of the action portion of the movable ring (e.g., the lowermost movable ring 20a) closest to the stopper portion 32 corresponds to the stopper portion 32. Therefore, when the rotatable member 10 rotates, the movable rings 20a and 20b can be driven to rotate by the acting portions 22a and 22b until the acting portions are stopped between the positioning portion 12 and the stopping portion 32.

Furthermore, as shown in fig. 5B, the acting portions and the stopping portions of the movable rings are preferably staggered left and right along a virtual line L parallel to the axial direction. For example, the movable ring 20a may be disposed such that the acting portion 22a is located in a counterclockwise direction of the stopper portion 32 (i.e., on the right side of the virtual line L), and the movable ring 20b may be disposed such that the acting portion 22b is located in a clockwise direction of the acting portion 22a (i.e., on the left side of the virtual line L). In another aspect, the position of the stopping portion 32 can be defined as a first side, the position of the acting portion 22a of the movable ring 20a close to the stopping portion 32 can be defined as a second side, and the positioning portion 12, the acting portions 22a, 22b and the stopping portion 32 are respectively arranged along the extending direction of the first side and the extending direction of the second side in a staggered manner. Specifically, the stopper portions 32, the plurality of operating portions 22a and 22b, and the positioning portions 12 are preferably arranged in two rows in the axial direction of the support shaft 31. That is, the action portions (e.g., 22a) of the movable rings (e.g., 20a) closest to the stopper 32 and the stopper 32 are located at the lowermost of the two rows, respectively, and the action portions of the axially adjacent movable rings are located at different rows, respectively, i.e., the remaining movable rings except the movable ring (e.g., 20a) closest to the stopper 32 are axially aligned with the stopper 32 and the action portions (e.g., 22a) of the movable rings (e.g., 20a) closest to the stopper 32, respectively.

It should be noted that, to achieve the bi-directional positioning with the same angle, the positioning portion 12 of the rotatable member 10 is preferably arranged to vary according to the number of the movable rings. Specifically, when the number of the movable rings is odd (as shown in the embodiment of fig. 1A), the positioning portions 12 of the rotatable member 10 are preferably arranged along the virtual line L on the same side as the stopping portions 32; when the number of the movable rings is even, the positioning portion 12 and the stopping portion 32 of the rotatable member 10 are preferably arranged at a difference of 180 degrees, for example, the positioning portion 12 and the stopping portion 32 of the rotatable member 10 are located at two opposite sides with respect to the supporting shaft 31. For example, in this embodiment, the number of the movable rings 20a and 20b is two, so the positioning portion 12 and the stopping portion 32 of the rotatable member 10 are preferably arranged 180 degrees apart, and a bidirectional positioning of ± 540 degrees can be realized.

When the rotatable member 10 rotates relative to the supporting member 30, the portion of the positioning portion 12 pushes against the upper portion 222b of the acting portion 22b of the movable ring 20b close to the positioning portion 12, and the lower portion 224b of the movable ring 20a close to the positioning portion 12 pushes against the upper portion 222a of the adjacent movable ring 20a, and the adjacent movable rings 20b and 20a are sequentially driven to rotate by the acting portions 22a and 22b until the stopping portion 32 stops the lower portion 224a of the movable ring 20a close to the stopping portion 32, and the acting portions 22a and 22b are stopped between the positioning portion 12 and the stopping portion 32. Specifically, referring to fig. 5B and fig. 6A, when the rotatable element 10 rotates about 540 degrees in the first rotation direction R1 (e.g., clockwise), the portion of the positioning portion 12 of the rotatable element 10 abuts against the upper portion 222B of the acting portion 22B of the movable ring 20B when rotating about 180 degrees, and pushes against the upper portion 222B of the acting portion 22B to rotate the ring main body 21B. Then, in the process that the rotatable element 10 drives the movable ring 20b to continue to rotate about 360 degrees in the first rotation direction R1 (i.e., clockwise direction), the lower portion 224b of the acting portion 22b abuts against the upper portion 222a of the acting portion 22a of the movable ring 20a and pushes against the upper portion 222a of the acting portion 22a to drive the ring main body 21a to rotate until the lower portion 224a of the acting portion 22a contacts the stopper 32, so that the acting portions 22a and 22b are stopped between the positioning portion 12 and the stopper 32, and further about 540 degrees clockwise positioning of the rotatable element 10 is achieved.

Further, referring to fig. 5B and fig. 6B, when the rotatable element 10 rotates about 540 degrees in the second rotation direction R2 (e.g., counterclockwise) opposite to the first rotation direction R1, the portion of the positioning portion 12 of the rotatable element 10 will first abut against the upper portion 222B of the acting portion 22B of the movable ring 20B and push against the upper portion 222B of the acting portion 22B to drive the ring main body 21B to rotate when rotating about 180 degrees. Then, in the process that the rotatable element 10 drives the movable ring 20b to continue to rotate about 360 degrees in the second rotation direction R2 (i.e., counterclockwise direction), the lower portion 224b of the acting portion 22b abuts against the upper portion 222a of the acting portion 22a of the movable ring 20a and pushes against the upper portion 222a of the acting portion 22a to drive the ring main body 21a to rotate until the lower portion 224a of the acting portion 22a contacts the stopper portion 32, so that the acting portions 22a and 22b are stopped between the positioning portion 12 and the stopper portion 32, thereby positioning the rotatable element 10 about 540 degrees counterclockwise.

In the embodiments of fig. 3A-3B and 4A-4B, the bidirectional positioning angle can also be increased by increasing the number of movable rings, for example, the bidirectional positioning of about ± 450 (270 +180) degrees. In other words, the embodiments of fig. 5A-5B can also change the number and positions of the stopping portions and the acting portions according to practical applications to achieve bidirectional positioning of less than ± 540 degrees, which is not described herein again.

Further, the rotating apparatus of the present invention can be applied to rotating a rotatable member by power. In another embodiment, as shown in fig. 7A to 7C, the rotating device 3 includes a rotatable member 100, a movable ring 200 and a support member 300. In this embodiment, the rotating device 3 preferably further comprises a driving gear 400 for receiving power to rotate and driving the rotatable member 100 to rotate. Specifically, the rotatable member 100 preferably includes a rotating ring 110 and a shaft portion 120, and the positioning portion 112 axially protrudes from the peripheral edge of the rotating ring 110 and partially overlaps the movable ring 200. The rotating ring 110 is fixedly secured to the shaft portion 120, and the rotatable member 100 is rotatably disposed on the support member 300. In this embodiment, the supporting member 300 preferably includes a base 310, and the stopping portion 320 is fixed on the base 310.

For example, the rotating ring 110 may include a gear portion 111, and the gear portion 111 is meshed with the driving gear 400, such that the driving gear 400 receives power from a motor, for example, to rotate, and drives the gear portion 111 to rotate, thereby driving the rotatable member 100 to rotate, but not limited thereto. In other embodiments, depending on the application, the rotatable element 100 may be driven by a driving device (e.g., a motor) without being driven by the driving gear 400, or the rotatable element 100 may be rotated by an external force applied by a user without providing a driving device.

As shown in fig. 7A, in an embodiment, the driving gear 400 is preferably disposed on the base body 310 corresponding to the rotatable element 100, but not limited thereto. In other embodiments, the driving gear 400 may be disposed independently from the base 310 according to practical applications. In this embodiment, the base 310 preferably has a receiving groove 312, and the rotatable member 100 is partially inserted into the receiving groove 312 and can rotate in the receiving groove 312 relative to the base 310. For example, the gear portion 111 and the shaft portion 120 are coaxially disposed, such that the shaft portion 120 is rotatably inserted in the accommodating groove 312, and the gear portion 111 and the shaft portion 120 can rotate together relative to the seat body 310, but not limited thereto. In other embodiments (not shown), the shaft portion 120 can be integrated with the housing 310, and the rotatable member 100 is preferably an annular gear portion 111, so that the gear portion 111 is rotatably sleeved on the shaft portion of the housing 310, and the gear portion 111 can rotate relative to the shaft portion of the housing 310.

furthermore, similar to the previous embodiment, the movable ring 200 and the rotatable element 100 are coaxially disposed between the rotatable element 100 and the supporting element 300, and the rotatable element 100 drives the movable ring 200 to rotate, and the stopping portion 320 stops the movable ring 200 to position the rotatable element 100. Specifically, the movable ring 200 includes a ring body 210 and an acting portion 220, and the acting portion 220 has two opposite ends 221, 223 along the circumference of the ring body 210. For example, the ring body 210 is preferably flat ring-shaped. The ring main body 210 is rotatably sleeved on the shaft portion 120 and located between the rotating ring 110 and the base 310, and the acting portion 220 axially extends such that an upper portion of the acting portion 220 corresponds to the positioning portion 112 and a lower portion of the acting portion 220 corresponds to the stopping portion 320. In one embodiment, the acting portion 220 of the movable ring 200 may be an arc-shaped protrusion that protrudes radially and extends downward concentrically with the ring main body 210, and the arc length of the acting portion 220 extending along the ring main body 210 has a corresponding predetermined central angle. In other words, the acting portion 220 has a first end 221 and a second end 223, and an included angle between the first end 221 and the second end 223 and the center of the circle is a central angle. For example, the central angle of the acting portion 220 is preferably 90 degrees, but not limited thereto, with a bi-directional orientation of about ± 270 degrees. The central angle of the acting portion 220 may vary according to the positioning angle.

In this embodiment, the stopping portion 320 is preferably a stopper disposed on the seat body 310 to correspond to the acting portion 220 of the movable ring 200, and the positioning portion 112 may be a block protruding from the lower side of the gear portion 111. In an embodiment, the positions of the positioning portion 112, the acting portion 220 and the stopping portion 320 are preferably located on the circumference of the same circle, and the horizontal projections of the positioning portion 112 and the stopping portion 320 in the axial direction are not overlapped (i.e. the heights are different), and the horizontal projection of the acting portion 220 in the axial direction is preferably partially overlapped with the positioning portion 112 and the stopping portion 320 respectively, i.e. the axial position of the acting portion 220 is preferably between the positioning portion 112 and the stopping portion 320, wherein a part of the acting portion 220 corresponds to the positioning portion 112, and another part of the acting portion 220 corresponds to the stopping portion 320.

Similar to the embodiment of fig. 4A, when the rotatable element 100 rotates clockwise (for example, about 270 degrees), the portion of the positioning portion 112 of the rotatable element 100 pushes against the second end 223 of the acting portion 220 of the movable ring 200, and further drives the movable ring 200 to move until the first end 221 of the acting portion 220 contacts the stopping portion 320, so that the acting portion 220 is stopped between the positioning portion 112 and the stopping portion 320, and further the rotatable element 100 is positioned about 270 degrees clockwise. Furthermore, similar to the embodiment of fig. 4B, when the rotatable element 100 rotates counterclockwise (for example, about 270 degrees), the portion of the positioning portion 112 of the rotatable element 100 pushes against the first end 221 of the acting portion 220 of the movable ring 200, and further drives the movable ring 200 to move until the second end 223 of the acting portion 220 contacts the stopping portion 320, so that the acting portion 220 is stopped between the positioning portion 112 and the stopping portion 320, and further the counterclockwise positioning of the rotatable element 100 is about 270 degrees.

In summary, the rotating device of the present invention can provide a bidirectional positioning function greater than 180 degrees. Furthermore, the rotating device of the invention can increase the bidirectional limiting angle and the bidirectional rotating number by increasing the number of the movable rings.
