Radial movement of the shaft member 200. Each of the fixing members 500 is fixedly connected to the corresponding second transmission member 420, and each of the plate members 21 and 22 is fixed to the corresponding fixing member 500. That is to say, when the shaft member 200 rotates, the fixing member 500 and the plates 21 and 22 fixed to the fixing member 500 are driven to move horizontally.

Moreover, each of the sliding members 600, the relay transmission members 430 and the second transmission members 420 are sandwiched between the corresponding limiting members 700 and the fixing members 500. Specifically, when the two plate members 21 and 22 rotate relative to each other, the carrier plate 100 is rotated relative to the shaft member 200, and the carrier plate 100 drives the transmission helical gear 411 of the first transmission member 410 to rotate together, and the helical gear is driven. When the 411 rotates, the relay helical gear 431 of the relay transmission member 430 rotates together with the relay spur gear 432, and when the relay spur gear 432 rotates, the rack 421 of the second transmission member 420 is driven to move horizontally ( Moving in a horizontal direction along the radial direction of the shaft member 200).

FIG. 5 is a partially enlarged schematic view showing the hinge 10 of the embodiment of the present invention at 90 degrees, and FIG. 6 is a partially enlarged schematic view showing the hinge 10 of the embodiment of the present invention at 0 degrees. FIG. 7 is a schematic diagram of the flexible display member when the electronic device 20 of the embodiment is in an unfolded angle. Among them, the plate member 21 is not shown in Figs. 5 and 6, so that the structure of the hinge 10 can be more clearly shown. As shown in FIG. 5, when the hinge 10 is at 90 degrees, the carrier 100 is rotated 45 degrees with respect to the two-axis member 200, and the two plates 21, 22 are moved by half of the stroke, so that the plates 21, The distance between the 22 and the hinge 10 is a centered distance, at which time the two plates 21, 22 are sandwiched by a 90 degree angle.

As shown in FIG. 6, when the hinge 10 is at 0 degrees, the carrier 100 is not rotated relative to the two-axis member 200, and the two plates 21, 22 are in an initial position, that is, the plates 21, 22 are separated from the hinge 10. In the nearest position, at this time, the two plates 21, 22 are sandwiched at an angle of 0 degrees, that is, the two plates 21, 22 are closed to each other. As shown in FIG. 7, when the two plates 21, 22 are relatively unfolded to the deployment angle, that is, when the hinge 10 is at 180 degrees, the carrier 100 is rotated 90 degrees with respect to the two-axis member 200, and the two plates 21, 22 are respectively rotated. In the farthest position, that is, the position where the plates 21, 22 are farthest from the hinge 10, at this time, the two plates 21, 22 are sandwiched by a 180 degree angle. At this time, since the two second transmission members 420 are respectively driven by the two relay transmission members 430 and horizontally moved in the opposite direction and reach the maximum stroke, the two plate members 21, 22 have the farthest distance from each other. The pitch is a specific distance corresponding to the intermediate portion of the flexible display member 23, and also because the two plates 21, 22 are spaced apart from each other by the specific distance, so that the flexible display member 23 attached to the two plates 21, 22 can be Pull open to form a flat surface without any bulging.

In summary, according to the present invention, a hinge device and an electronic device using the same, when the two plates of the electronic device are in an unfolded state, the two plates are apart from each other according to the angle of expansion, until this When the two plates are fully deployed to form a deployed state, the two plates are spaced apart by a specific distance, and the specific distance corresponds to the middle portion of the flexible display member, which causes the flexible display member to form a flat surface, thereby avoiding the existing The intermediate portion of the flexible display member of the electronic device has the disadvantage of bulging when the electronic device 20 is in the unfolded state.
