When the electronic device 20 is at 0 degree, each rotating block 140 and the corresponding connecting member 130 are retracted inward at 0 degree. That is, each of the rotation blocks 140 is inwardly pivoted at an angle with the positioning pin shaft 150 as a rotation center. In this embodiment, six positioning pins 150 are used, that is, two adjacent rotating blocks 140 (or two adjacent rotating blocks between the first fixing member 110 and the second fixing member 120) on each positioning pin 150 complete 30 degrees of rotation, so that the hinge 100 can rotate between 0 and 180 degrees. The axis of the positioning pin shaft 150 corresponds to the first upper edge 1311 and the first upper edge 1321 of two adjacent connectors 130. Therefore, each connecting element 130 can also be regarded as rotating around the axis of the corresponding positioning pin shaft 150.

Referring to fig. 5 and fig. 7 to 10, fig. 5 is a schematic front view of the hinge 100 of the electronic device 20 shown in fig. 1 at 180 degrees, fig. 7 is a schematic front view of the electronic device 20 shown in fig. 1 at 90 degrees, fig. 8 is a schematic front view of the hinge 100 of the electronic device 20 shown in fig. 7 at 90 degrees, fig. 9 is a schematic front view of the electronic device 20 shown in fig. 1 at 0 degree, and fig. 10 is a schematic front view of the hinge 100 of the electronic device 20 shown in fig. 9 at 0 degree. As shown in fig. 1, 7 and 9, the electronic device 20 is sequentially folded from 180 degrees to 90 degrees and finally to 0 degree. Under the condition that the electronic device 20 is at 180 degrees, 90 degrees and 0 degrees, as shown in fig. 5, 8 and 10, the hinge device 100 is also at 180 degrees, 90 degrees and 0 degrees respectively. As shown in fig. 5, 8 and 10, in the process of bending the hinge device 100 from 180 degrees to 0 degrees (or from 0 degree to 180 degrees), the first fixing element 110 and the corresponding rotating block 140 pivot relatively to each other, so as to synchronously drive the opposite connecting elements 130, and enable the two adjacent connecting elements 130 to pivot relatively to each other, and the second fixing element 120 and the corresponding rotating block 140 also drive the opposite connecting elements 130 to pivot relatively to each other, and the third upper edge 1111 of the first fixing element 110 and the second supporting portion 142 of the adjacent rotating block 140, the first tapered surface 1421 of the first supporting portion 142, the fourth upper edge of the second fixing element 120 and the second supporting portion 142 of the adjacent rotating block 140, the second tapered surface 1422 of the second supporting portion 142, the first upper edge 1311 of the first adjacent edge 131 of the connecting element 130 and the second upper edge 1321 of the second adjacent edge 132 of the adjacent connecting element 130 all keep abutting (or contacting) against each other between 0 degree and 180 degrees, that is, the outer edge (i.e., the lower edge as viewed in fig. 3) of the hinge 100 maintains a fixed length, while the inner edge of the hinge 100 is the portion to which the flexible display panel 23 is attached. The outer edge of the hinge 100 maintains a fixed length, and the first arc 133 section of each connecting member 130 between the connecting members 130, which is adjacent to the upper edge of the first adjacent edge 131 and the second adjacent edge 131, can create a space for the flexible display panel 23 to extend when the flexible display panel 23 is folded, thereby ensuring that the flexible display panel 23 is not compressed by the folding or unfolding of the electronic device 20. That is, when the electronic device is folded, since the upper edge of each connecting member is provided with the first arc surface 133, the flexible screen panel 23 will receive a little length of the flexible screen panel 23 extended by the folding through the first arc surface 133 when the flexible screen panel is folded, thereby preventing the flexible screen panel 23 from being broken.

In the present embodiment, the overall rotation angle is 180 degrees, but is not limited thereto. When the number of the rotating blocks 140 and the connecting members 130 is five, and the first fixing member 110 and the second fixing member 120 are added, the total number of the six positioning pins is six, so that the six sets of components pivot relative to each other, and if each set is configured to bear a rotation angle of 30 degrees, the configuration can allow the hinge device 100 to achieve a rotation angle of exactly 180 degrees. In other embodiments, different arrangements and different numbers of sets (e.g., different numbers of rotating blocks 140 and connecting members 130) can achieve the desired rotation angle of the hinge 100, which can be 180 degrees or a rotation angle different from 180 degrees. In other embodiments, if each group is configured to bear a rotation angle different from 30 degrees, the pivot device 100 can achieve the desired rotation angle, which may be 180 degrees or a rotation angle different from 180 degrees.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
