As can be clearly seen from Fig. 1, the rotating mechanism 100 exposed after the support member 14 is turned out has a simple curved surface in appearance, and does not expose the external gear or other redundant components, and is relatively simple and beautiful in appearance. The detailed components of the rotating mechanism 100 will be explained in detail below.

2 is a schematic view of a rotating mechanism of the electronic device of FIG. 1. Figure 3 is a schematic illustration of the arcuate rotating member of the rotating mechanism of Figure 2 being rotated out. Figure 4 is a schematic exploded view of the rotating mechanism of Figure 2. 5 and 6 are schematic views of other perspectives of the second housing of the rotating mechanism of FIGS. 2 and 3.

Referring to FIG. 2 to FIG. 6 , the rotating mechanism 100 of the embodiment includes a base 110 , a rotating shaft 120 and an arc-shaped rotating member 130 . The base 110 includes a first housing 111, a second housing 112, a plurality of fixing members 113, and an arcuate inner rail 114. The curved inner rails 114 are formed in the first housing 111 and the second housing 112 together, and the first housing 111 and the second housing 112 are fixed to each other by the fixing members 113. In this embodiment, the fixing member 113 is, for example, a latch, but the type of the fixing member 113 is not limited thereto. In other embodiments, the fixing member 113 may also be a screw, a rivet or an adhesive layer. In addition, in other embodiments, the base 110 may also include only a single fixing member 113. The first housing 111 and the second housing 112 are fixed to each other by the fixing member 113, and the number of the fixing members 113 is not limit.

The rotating shaft 120 is pivotally connected to the first housing 111 of the base 110 and includes an external gear 122, wherein the external gear 122 is located beside the curved inner rail 114. The curved rotating member 130 is received in the curved inner rail 114 and includes a rack 132 positioned on the inner surface. The rack 132 of the curved rotating member 130 is engaged with the external gear 122 of the rotating shaft 120, so that the curved rotating member 130 can partially protrude from the base 110 as the rotating shaft 120 rotates.

In addition, in the embodiment, the first housing 111 and the second housing 112 of the base 110 respectively include first fixing portions 116, 117, and the curved rotating member 130 includes a second fixing portion 136, and the first fixing portion 116, 117 can be locked to the body 12, and the second fixing portion 136 can be locked to the support member 14, so that the support member 14 can pass through the relative rotation of the arc-shaped rotating member 130 and the base 110 in the rotating mechanism 100 relative to the body. 12 turns. In this embodiment, the support member 14 can be rotated relative to the body 12 to an angle of 125 degrees. Of course, the designer can adjust the curvature of the arc-shaped rotating member 130 according to requirements to provide a sufficient range of rotation.

In addition, in the embodiment, the rotating mechanism 100 further includes a torsion assembly 140 that is sleeved on the rotating shaft 120 to serve as a source of torque of the rotating shaft 120. In the present embodiment, the torsion assembly 140 includes a spring piece and a nut, and the nut is pushed by the nut to provide a torque for rotating the shaft 120. In this way, after the user applies the force to turn the support member 14 to a predetermined position (for example, the position shown in FIG. 1 or any other position not shown), the support member 14 can stay there. Of course, in other embodiments, the torsion assembly 140 can also be other components that can provide friction to the sides of the shaft 120, such as a rough wall having a side that contacts the shaft 120, as well as providing torque for the rotation of the shaft 120. Achieve the above functions.

Fig. 7 is a schematic cross-sectional view taken along line A-A of Fig. 2; Fig. 8 is a schematic cross-sectional view taken along line B-B of Fig. 3. Referring to FIG. 4, FIG. 7, and FIG. 8, in the embodiment, the support member 14 is separated from the body 12 in order to prevent the arc-shaped rotating member 130 from being separated from the base 110 during the process of transferring out of the base 110. As shown in FIG. 7 and FIG. 8, the base 110 has a limiting wall 115 near the outer gear 122. The arc-shaped rotating member 130 has a limiting protrusion 134 at the end of the rack 132. In this embodiment, The extending length of the limiting protrusion 134 is greater than the length of each protrusion on the rack 132. The position of the limiting wall 115 corresponds to one end of the limiting protrusion 134. During the rotation of the curved rotating part 130, due to the rack The length of each of the protrusions 132 is short and is not restricted by the limiting wall 115. When the curved rotating member 130 is rotated until the limiting protrusion 134 contacts the limiting wall 115, the curved rotating member 130 can no longer continue to rotate. The curved rotating member 130 is not separated from the curved inner rail 114.

In summary, the electronic device of the present disclosure has a support member for supporting the body. The electronic device of the present disclosure is fixed to the base of the rotating mechanism by the body, and the support member is fixed to the curved rotating member of the rotating mechanism, and the arc is transmitted through the arc. The rack on the rotating member engages with the external gear of the rotating shaft to enable the support to be rotated relative to the body to a desired angle. In addition, since the external gear is located in the base, only a part of the arc-shaped rotating member protrudes from the base, and the rack of the curved rotating member is located on the inner surface, so that the electronic device of the present disclosure can maintain a simple and beautiful appearance. .

The present disclosure has been disclosed in the above embodiments, but it is not intended to limit the disclosure, and any person skilled in the art can make some changes and refinements without departing from the spirit and scope of the disclosure. The scope of protection of this disclosure is subject to the definition of the scope of the appended claims.
