Referring to FIG. 2 to FIG. 5 , the rotating structure 100 of the embodiment includes a first housing 110 , a rotating component 120 , a flexure 130 , and a second housing 140 . The rotating member 120 includes a plurality of first positioning portions 122 and a cylinder 124, and the first positioning portions 122 surrounds the circumferential side of the cylinder 124. In the embodiment, the first positioning portions 122 are grooves surrounding the periphery of the cylinder 124 , and the first positioning portions 122 extend toward the axis direction A of the cylinder 124 . However, in other embodiments, the types of the first positioning portions 122 are not limited thereto.

The flexure 130 includes opposite end portions 132, a resilient arm 134, and a The second positioning portion 136 is fixed to the first housing 110. The elastic arm 134 is connected to the two ends 132 and located between the two ends 132. The second positioning portion 136 is located at the elastic portion. On the arm 134. As shown in FIG. 4, the elastic arm 134 and the two end portions 132 are located on different planes. In the present embodiment, the second positioning portion 136 is a rib, and the second positioning portion 136 extends toward the axial direction A of the cylinder 124. However, in other embodiments, the type of the second positioning portion 136 is not limited thereto.

The rotating member 120 is located at the first housing 110 and the flexure 130 Between the elastic arms 134, the second positioning portion 136 of the flexure 130 is adjustably engaged with one of the first positioning portions 122 of the rotating member 120, so that the rotating member 120 can be opposite The multi-section rotational positioning is performed on the flexure 130.

The second fixing portion 14a needs to be set compared to the conventional rotating structure 10. The fixing member 14 and the spring 16 provide pressure between the rotating member 12 and the fixing member 14 and provide a margin for rotating the rotating member 12 relative to the fixing member 14. In the present embodiment, the above function can be achieved by the flexure 130.

In detail, in this embodiment, the second positioning portion 136 is located at the scratch The elastic member 134 of the member 130 is fixed to the first housing 110, and the elastic arm 134 can provide the first positioning portion 122 and the The pressure between the second positioning portions 136 ensures that the first positioning portion 122 is engaged with the second positioning portion 136. Moreover, since the elastic arm 134 is flexible relative to the both end portions 132, the elastic arm 134 can also provide a margin for rotating the rotating member 120. That is, when the user rotates the rotating member 120, the second positioning portion 136 of the flexure 130 can move along the contour of the first positioning portion 122 of the rotating member 120 to be engaged with the rotating member. The next first positioning portion 122 of 120. Therefore, the rotating structure 100 of the present embodiment effectively reduces the number of components and is more convenient in assembly.

In this embodiment, the first housing 110 includes two first fixing portions 112. Each end portion 132 of the flexure 130 includes a second fixing portion 132a corresponding to one of the first fixing portions 112. In this embodiment, the first fixing portion 112 and the second fixing portion 132a are respectively a corresponding hook and a card hole, but the two ends 132 of the flexure 130 and the first housing The fixing method of 110 is not limited thereto. In other embodiments, the two ends 132 can also be screwed or glued to the first housing 110, or directly the two ends 132 of the flexure 130 and the first one during manufacture. The housing 110 is manufactured in an integrally formed manner.

In addition, in order to make the second positioning portion 136 of the flexure 130 and the card The first positioning portion 122 of the rotating member 120 can be more stably engaged with each other. The second housing 140 includes a rib 142. The second housing 140 is fixed to the first housing 110 and the rib is fixed. The portion 142 abuts against the resilient arm 134 of the flexure 130 to maintain substantially the same pressure between the second positioning portion 136 and the first positioning portion 122 that is engaged.

That is, the second positioning portion 136 and the first positioning portion that is engaged The locking tightness between the two ends is fixed to the first housing 110 by the two ends 132 of the flexure 130, so that the elastic arm 134 of the flexure 130 can position the second positioning portion. In addition to the direction of the first positioning portion 122, the rib 142 of the second housing 140 is further abutted against the elastic arm 134. In the embodiment, the rib 142 abuts the elasticity. The position of the arm 134 is the other side of the second positioning portion 136 at the position of the elastic arm 134, so that the second positioning portion 136 can be more stably engaged with the first positioning portion 122.

Because the rib 142 is opposite to the second housing 140 and the flexure 130 The position of the first housing 110 is fixed. When the second housing 140 is fixed to the first housing 110, the pressure applied to the elastic arm 134 by the rib 142 is fixed, which can be prevented from being assembled by different components. When the two components are assembled, the degree of tightness of the engagement between the second positioning portion 136 and the first positioning portion 122 is different. Therefore, the second positioning portion 136 and the first positioning portion 122 that is engaged can maintain substantially the same degree of engagement.

In addition, since the rotating member 120 has a cylindrical shape, it is placed in the first shell. On the body 110, the front and rear sides of the position of the first housing 110 may be easily swayed or shaken, since the rotating member 120 is located between the first housing 110 and the second housing 140, The rotating member 120 is stably disposed. Figure 6 is a schematic illustration of the second housing of the rotating structure of Figure 2. Referring to FIG. 6 , the second housing 140 further includes a limiting portion 144. In the embodiment, the limiting portion 144 abuts the rotating member 120 along an axial direction A of the rotating member 120 to limit the The rotating member 120 swings in a direction A perpendicular to the axis.

In addition, returning to FIG. 3, the rotating structure 100 of the embodiment further includes a mirror. The head 150 is disposed on one side of the rotating member 120. In the present embodiment, the photographing direction of the lens 150 is perpendicular to the axial direction A of the cylinder 124. Therefore, when the rotating member 120 rotates relative to the first housing 110 and the second housing 140, the lens 150 can be photographed perpendicular to the axis direction A of the rotating member 120 as the rotating member 120 rotates. image. The rotating structure 100 of the embodiment can be applied to a driving recorder or a camera, and the user can adjust the angle of the lens 150 as needed to capture an image of a desired viewing angle. Of course, in other embodiments, the rotating member 120 can also be combined with other components to provide multi-segment rotational positioning when other components perform functions.

In summary, the rotating structure of the present invention has a plurality of circumferential sides of the rotating member The first positioning portion, the flexible member located on one side of the rotating member can be engaged with the first positioning portion of the rotating member by the second positioning portion to achieve multi-stage rotational positioning. Since the flexure is fixed to the first housing by the two ends, a gap exists between the elastic arm and the first housing to accommodate the rotating member, and when the rotating member is rotated, the two are located The elastic arm between the ends can provide a margin for the second positioning portion to be withdrawn or engaged with the first positioning portion, and only the two ends need to be fixed when the flexible member is assembled to the first housing Very convenient. In addition, when the rotating structure of the present invention is fixed to the first casing through the second casing, the rib of the second casing is pressed against the elastic arm to strengthen the second positioning portion and the engaged The degree of engagement between the first positioning portions is such that the degree of engagement between the first positioning portion and the second positioning portion of the rotating structure can be uniform even if assembled by different assemblers.
