Also, the first pitch L1 is substantially equal to the fourth pitch L4, and the second pitch L2 is substantially equal to the third pitch L3. Since the link set 200 adjacent to the second fixing member 120 is the only set of the link set 200 for this purpose, the third end portion 223 of the link set 200 is slidably coupled to the first fixing member 110, and the fourth end portion 224 The second fixing member 120 is pivotally connected to the second fixing member 120. The first intermediate portion 213 and the second intermediate portion 225 are pivotally connected to each other, and the first end portion 211 and the third end portion 223 are located on the same side with respect to the first intermediate portion 213 and the second intermediate portion 225. With this arrangement, since the link set 200 has only one set, the hinge 10 can be bent and unfolded with a limited degree, for example, bent and unfolded between 180 degrees and 150 degrees, and cannot have multiple sets as in the foregoing embodiment. The hinge 10 of the linkage set 200 can be bent and unfolded between 180 degrees and 0 degrees. In various embodiments, those skilled in the art can design the hub 10 to have a particular set of linkages 200, depending on the range of angles of bending and deployment as desired.

They are also respectively disposed in the two chutes 111, 121. Moreover, the chutes 111 and 121 are all linear. For example, the first sliding shaft 2231 is axially extended by the third end portion 223 and is disposed in the sliding slot 111 of the first fixing member 110. Similarly, the second sliding shaft 2121 is configured by the second end portion 212. The extension is inserted into the sliding slot 121 of the second fixing member 120.

That is, when the hinge 10 is bent or unfolded between 0 degrees and 180 degrees, the first link 210 adjacent to the first fixing member 110 may have a coaxial axis with the first end portion 211 and the pivot hole 112. The rotation of the center of rotation is performed, and the second link 220 adjacent to the second fixing member 120 rotates with the coaxial axis of the fourth end portion 224 and the pivot hole 122 as a center of rotation. Moreover, the first sliding shaft 2231 and the second sliding shaft 2121 are respectively bent in the sliding grooves 111, 121 as the hinge 10 is bent or unfolded between 0 degrees and 180 degrees.

Please refer to FIG. 5, FIG. 6, and FIG. 7, which are side views of the hinge 10 being expanded to 180 degrees, bent to 90 degrees, and bent to 0 degrees, respectively. The sequence of Figures 5, 6 and 7 shows the process of bending the hinge 10 from 180 degrees (Fig. 5) to 90 degrees (Fig. 6) and then to 0 degrees (Fig. 7); otherwise, Fig. 7 and Fig. 6 The sequence of Figure 5 shows the process in which the hub 10 is deployed from 0 degrees (Figure 7) to 90 degrees (Figure 6) and then to 180 degrees (Figure 5). When the hinge 10 is 180 degrees, the electronic device 20 is correspondingly 180 degrees, as shown in FIG. 2, when the first plate 21 and the second plate 22 are opposite to each other to 180 degrees; when the hinge 10 is At 90 degrees, the electronic device 20 is correspondingly 90 degrees, at which time the first plate 21 and the second plate 22 are folded or unfolded relative to each other to 90 degrees; when the hinge 10 is 0 degrees, the electronic device 20 correspondingly At 0 degrees, as shown in FIG. 1, the first plate member 21 and the second plate member 22 are folded to each other at 0 degrees. During the process of the user pulling the first plate member 21 and the second plate member 22 and connecting the bending or unfolding of the hinge 10, the first link 210 and the second link 220 of each link set 200 are The included angle will change accordingly, however, this does not change the distance of the link set 200 between the inner edge of the first fixture 110 and the second fixture 120, as further explained below.

Referring to FIG. 5, the pivot hole 112 of the first fixing member 110 (the coaxial axis with the coaxial first end portion 211) and the pivot hole 122 of the second fixing member 120 (with the coaxial fourth end portion 224) are defined. The length between the coaxial axes) is X. That is, when the hinge 10 is 180 degrees, the length of the inner edge of the link set 200 (the length of the inner edge is the length of the upper side of the link set 200 in the lateral direction in the drawing) as seen in FIG. 5 X; when the hinge 10 is 90 degrees, the length of the inner edge of the link set 200 (the length of the inner edge of the link set 200 as seen in FIG. 6) is defined as X1; when the hinge 10 At 0 degrees, the length of the inner edge of the link set 200 (the length of the inner edge of the link set 200 as seen in Fig. 7) is defined as X2. In the present creation, the first fixing member 110 must be unfolded by 180 degrees with respect to the second fixing member 120. Therefore, this creation uses multiple link sets. For example, this creation uses six linkage sets, and each linkage group is responsible for a 30 degree deployment angle. Further, the present invention is calculated such that the inner edge of the link set 200 has an arc length X1 of 90 degrees or an arc length X2 of 0 degrees, which may be equal to the arc length X of the inner edge of the link set 200 at 180 degrees. . Thereby, regardless of the relative expansion of the first plate member 21 and the second plate member 22 to any angle, the length of the inner edge of the hinge 10 (i.e., the arc length of the inner edge of the plurality of link sets 200) remains unchanged. Therefore, the flexible display member disposed on the inner edge of the first plate member 21, the second plate member 22 and the link set 200 is not pressed by the folding of the hinge 10, and may be damaged or not. The tension is caused by the deployment of the hinge 10 and may cause damage.

In this embodiment, when the hinge 10 is deployed to 180 degrees, as shown in FIG. 5, the first sliding shaft 2231 and the second sliding shaft 2121 are slid in the corresponding sliding slots 111, 121 to one end of the sliding slot; The hinge 10 is bent to 0 degrees. As shown in FIG. 7, the first sliding shaft 2231 and the second sliding shaft 2121 are slid in the corresponding sliding grooves 111, 121 to the other end of the sliding slot, because the first connecting rod 210 The angle with the second link 220 may change during the bending of the hinge 10. When the hinge 10 is unfolded or bent to 90 degrees, as shown in FIG. 6, the first sliding shaft 2231 and the second sliding shaft 2121 may be in the middle of the two ends of the sliding groove in the corresponding sliding grooves 111, 121. Moreover, as shown in FIG. 4, FIG. 6, and FIG. 7, the first link 210 and the second link 220 of each link set 200 are disposed adjacent to the first intermediate portion 213 and the second intermediate portion 225. There is a slot 218. Therefore, when the electronic device is folded from 180 degrees of FIG. 5 to 0 degrees of FIG. 7, both the first end portion 211 and the fourth end portion 224 can be accommodated in the first link 210 and the first The lack of grooves 218 on the two links 220 allows the volume of the entire hinge 10 to be more flattened and reduced.

In summary, according to the present invention, a hinge and an electronic device using the same, when the hinge rotates, the length of the inner edge of the link group is always maintained, when the first plate and the first part of the electronic device When the two plates are relatively folded and relatively unfolded, the flexible display members disposed on the inner edges of the first plate member, the second plate member and the link group are not pressed or strained and may cause damage.

Although the technical content of the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention. Anyone who is familiar with the art, and some modifications and refinements that do not depart from the spirit of the present invention should be included in the creation. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application.
