In addition, a first guide groove 361 and a second guide groove 362 are formed on the inner surface of the case 360 to guide the end portions of the first shaft 312 and the second shaft 322. The first guide groove 361 and the second guide groove 362 support the first shaft 312 and the second shaft 322 to be stably moved without shaking during rotation.

Hereinafter, in the portable electronic device 1 equipped with the hinge device 300 according to the present invention, the deformation process from the expanded state to the folded state will be described with reference to FIGS. 6A to 6C and 7A to 7C. do.

6A to 6C, the first rotating body 310 and the first body 100, the second rotating body 320, and the second body 200 are all rotated, and FIGS. 7A to 6C are illustrated. In FIG. 7C, only the first pivotal body 310 and the first body 100 are rotated. In addition, for convenience of description, the case 360 is not shown in FIGS. 6 to 7, and in particular, the first elastic part 340 and the second elastic part 350 are excluded in FIG. 7. Has been shown.

6A shows the electronic device 1 in the unfolded state.

FIG. 7A illustrates a state in which the first body 100 and the second body 200 are in a 90 ° state (intermediate state), where the relative positions of the first rotating body 310 and the second rotating body 320 are shown. I can figure it out.

In the unfolded state, the first body 100 and the second body 200 are formed on the same plane, the electronic device 1 as a whole has a wide plate shape. In this case, the first actuating protrusion 311 and the second actuating protrusion 321 are located at the upper end of the first actuating slot 331 and the second actuating slot 332 and the first shaft 312. The second shaft 322 is located inside the first reciprocating slot 333 and the second reciprocating slot 334. Further, the first rotating body 310 and the second rotating body 320, respectively, It is a state that is elastically supported by the first elastic portion 340 and the second elastic portion 350, the extent to overcome the elastic force of the first elastic portion 340 and the second elastic portion 350 This state is maintained when no external force is applied.

That is, the first elastic cam 341 is pressed by the first spring 342 and stays below the first central inclined portion 336, and the first elastic cam 341 is the first center. The rotation of the first rotatable body 310 is prevented unless an external force is applied to climb the inclined surface of the inclined portion 336.

6B shows an intermediate process (which is different from the intermediate state) of changing from the expanded state to the folded state. That is, the first rotating body 310 and the second rotating body 320 shows a process of rotating both.

FIG. 7B illustrates a state in which the first body 100 and the second body 200 form a 45 ° state (only the first body 100 rotates), wherein the first rotating body 310 and the second body 200 are rotated. The relative position of the rotating body 320 can be grasped.

The first actuating protrusion 311 moves downwardly of the first actuating slot 331 while the first pivot 310 is rotated based on the central support 330 by the action of an external force. The first shaft 312 moves in the outward direction of the first reciprocating slot 333.

At this time, since the first operation slot 331 and the second operation slot (332) is formed in a convex shape to the outside, the first body 100 and the second body 200 is rotated while the distance between each other Slightly open, even when the end portion of the first image portion 110 and the end portion of the second image portion 210 are formed in close contact with each other, the rotation is not hindered.

In addition, the first spring 342 is elastically deformed in the direction in which the elastic force is most increased.

When the first actuating protrusion 311 does not exceed the intermediate point of the first actuating slot 331, the first actuating protrusion 311 returns to the intermediate state by the elastic force of the first elastic part 340, and exceeds the intermediate point. In this case, the state is converted to the folded state.

That is, the first elastic cam 341 rises along the inclined surface of the first central inclined portion 336 while overcoming the elastic force pressed by the first spring 342. However, even when a maximum elastic force acts on the first spring 342 (when the first actuating projection 311 is located at an intermediate point of the first actuating slot 331), the first elastic cam 341 is applied. Is formed on the inclined surface of the first central inclined portion 336.

6C and 7C show the electronic device 1 in the folded state.

The first body 100 and the second body 200 are overlapped and in close contact. In this case, the first actuating protrusion 311 and the second actuating protrusion 321 are located at the lower end of the first actuating slot 331 and the second actuating slot 332 and the first shaft 312. The second shaft 322 is located inside the first reciprocating slot 333 and the second reciprocating slot 334. Further, the first rotating body 310 and the second rotating body 320, respectively, It is a state that is elastically supported by the first elastic portion 340 and the second elastic portion 350, the extent to overcome the elastic force of the first elastic portion 340 and the second elastic portion 350 If no external force is applied, this state is also maintained.

That is, the first elastic cam 341 is pressed by the first spring 342 and stays below the first central inclined portion 336, and the first elastic cam 341 is the first center. The rotation of the first rotatable body 310 is prevented unless an external force is applied to climb the inclined surface of the inclined portion 336.

As such, the first elastic portion 340 and the second elastic portion 350 are located at the same point in the unfolded state and the folded state, and are moved reciprocally to move the first shaft 312 and the second shaft 322. By being coupled to ()), while the elastic deformation of the first elastic portion 340 and the second elastic portion 350 can be minimized while moving to minimize the space can be exhibited a strong elastic force.

In the intermediate state, the first pivot body 310 and the first body 100 are maintained in the shape of FIG. 7C while the second pivot body 320 and the second body 200 are illustrated in FIG. 6A. It can also be understood as a modified form.
