(The second bent portion 323 is inserted and coupled to the second coupling groove 220).

For convenience of manufacture, the hinge device 300 is first assembled and formed, and then coupled to the first body 100, and the formation of the first bent portion 313 facilitates this. In addition, by allowing the first body 100 and the first plate 310 to be coupled through the first bent portion 313, a firm coupling between the first body 100 and the first plate 310 may be ensured, and the rotation of the first body 100 may be performed. At the same time, the smooth operation of the hinge device 300 is achieved.

A second operation protrusion 321, a second reciprocating protrusion 322, and a second bent portion 323 are formed on the second plate 320, and are formed in a symmetrical form with the first plate 310. The second plate 320 is rotated while sliding relative to the center plate 330. The second plate 320 may rotate in conjunction with the first plate 310. Alternatively, the second plate 320 may be rotated with respect to the rotation of the first plate 310. You can rotate regardless. When the connection plate 370 to be described later is formed, the first plate 310 and the second plate 320 are rotated in conjunction with each other, and when the connection plate 370 is not formed, the first plate 310 and The second plate 320 is rotated without interlocking.

Here, the unfolded state and the folded state will be briefly described.

In the unfolded state, the first body 100 and the second body 200 are formed on the same plane, and the angle between them is 180 °. In the folded state, the first body 100 and the second body 200 overlap each other so that an angle between them is 0 °. In the portable electronic device 1 including the hinge device 300 according to the present invention, the intermediate state of the expanded state and the folded state, that is, the angle formed by the first body 100 and the second body 200 is 90 degrees. It may be °, which may be formed when the connection plate 370 to be described later is excluded. Here, the intermediate state does not refer to the form illustrated in FIG. 8, but only one of the first body 100 or the second body 200 rotates by 90 ° in the unfolded state. That is, when the connection plate 370 is excluded, the interlocking operation of the first plate 310 and the second plate 320 is not made, but instead of the first body 100 and the second body 200. It is possible to maintain the intermediate state in which the angle formed by the angle is 90 °.

The first actuating protrusion 311 and the second actuating protrusion 321 are located at an upper end of the first actuating slot 331 and the second actuating slot 332 in the unfolded state. 312 and the second reciprocating protrusion 322 are located at inner ends of the first reciprocating slot 333 and the second reciprocating slot 334. That is, the first elastic body 340 and the second elastic body 350 While the first body 100 and the second body 200 fixedly coupled to the first plate 310 and the second plate 320 are elastically supported by the same position on the same plane, the expanded state is elastic (If the strong force does not act enough to overcome the unfolded state, the unfolded state is kept stable.)

In addition, in the folded state, the first actuating protrusion 311 and the second actuating protrusion 321 are located at the lower ends of the first actuating slot 331 and the second actuating slot 332, and the first reciprocating The protrusion 312 and the second reciprocating protrusion 322 are positioned at inner ends of the first reciprocating slot 333 and the second reciprocating slot 334. That is, the first elastic body 340 and the second elastic body ( While the first body 100 and the second body 200 fixedly coupled to the first plate 310 and the second plate 320 supported by the 350 are folded to each other, the folded state is elastically stable. (If the external force is not strong enough to overcome the folded state, the folded state remains stable.)

The first elastic member 340 and the second elastic member 350 elastically support the first plate 310 and the second plate 320, and enable the semi-automatic operation of the hinge device 300 and the unfolded state. And stable maintenance of the folded state is possible.

The first elastic body 340, one end is fixed to the central plate 330 and the other end is connected to the first reciprocating protrusion (312). The first elastic member 340 presses the first reciprocating protrusion 312 to stay inside the first reciprocating slot 333 (inside of the central plate 330).

The first elastic body 340 is formed of a circular coil portion and a straight portion extending on the same plane at the end of the coil portion, the thickness of the coil portion is formed smaller than the width (T <W), That is, the coil part may be formed on the same plane as a whole, or may be formed in a form wound one or more times. Even when formed in a form wound one or more times, the coil portion is formed to a thickness smaller than a width, and the first elastic body 340 is formed. It is made to be formed in a relatively thin form.

The elastic body fixing protrusion 336 is coupled to one straight portion that is one end of the first elastic body 340, and the first reciprocating protrusion 312 is coupled to the other straight portion that is the other end.

The first elastic body 340 presses the first reciprocating protrusion 312 to stay inside the first reciprocating slot 333 (center side of the center plate 330), and thus the first operation. The protrusion 311 stays at the top or bottom of the first operation slot 331, and eventually the semi-automatic operation of the first body 100 is performed. This semi-automatic operation will be described later.

The first elastic body 340 is formed on the outer side of the central plate 330, the outer side of the path of the first actuating projection (311). That is, when the first operation slot 331 in which the first operation protrusion 311 is slid is formed at the center of the central plate 330, the first reciprocating slot 333 and the first elastic body 340 are formed. It is formed on the outer side of the central plate 330 and is coupled so as not to overlap the first operation slot 331. Accordingly, the first elastic body 340 provides a sufficient elastic force for semi-automatic operation, while allowing the hinge device 300 to be formed relatively thin.

As such, in the hinge device 300 according to the present invention, the first elastic body 340 is formed in a form capable of minimizing the thickness of the hinge device 300 while allowing semi-automatic operation. Utilizing the side space of the 100 and to prevent the interference in securing the size of the first image (110).

In addition, when the first elastic body 340 is coupled to the first plate 310 and the central plate 330, the first elastic body 340 is coupled in an elastically deformed form. That is, even when the first reciprocating protrusion 312 is located at the inner end of the first reciprocating slot 333, the elastic force by the first elastic body 340 may strongly act on the first plate 310. The first elastic body 340 is coupled to the first plate 310 and the center plate 330 in a compressed state in a direction in which elastic force increases.

As such, the first elastic body 340 is coupled in the form of an elastic deformation in advance, thereby being able to exert a sufficiently strong elastic force in the unfolded state and the folded state, and the first body 100 in the unfolded state and the folded state The second body 200 can be stably maintained without shaking.

The second elastic member 350 is formed in a symmetrical form with the first elastic body 340, and the second plate 320 is made to slide relative to the center plate 330 to perform a semi-automatic operation during rotation. .

Hinge device 300 according to a preferred embodiment of the present invention, is coupled to the outside of the central plate 330, the first elastic member 340 and the second elastic member 350 is accommodated therein, and forms an outer surface The case 360 is formed. In addition, the case 360 allows the connection plate 370 to be described later to be accommodated, and constitutes an outer surface of the hinge device 300.

When the case 360 is assembled to the central plate 330, the first elastic body 340 and the second elastic body 350 are assembled, and the connection plate 370 is assembled. Fastening rings 361 are formed at the upper and lower ends for the convenience of the fastening ring 361 is caught by the fastening grooves 335 of the central plate 330 and the case 360 and the central plate 330. Will be assembled. The case 360, the thickness is made to be the same as the portion connected to the first body 100 and the second body 200, it is made so that it can be harmonized in appearance.

5 is a side view showing a part of the configuration of the hinge device 300 shown in Figure 3, Figure 6 is a side view showing a part of the configuration of the hinge device 300 according to another embodiment of the present invention.

Hinge device 300 according to a preferred embodiment of the present invention further comprises a connection plate 370, Figure 5 is a hinge device 300 of the form in which the connection plate 370 is not formed, Figure 6 The hinge plate 300 of the form in which the connection plate 370 is formed is shown, respectively.

The connection plate 370 is for interlocking when the first plate 310 and the second plate 320 are rotated, and when the connection plate 370 is not provided, the connection plate 370 is connected to the first plate 310. The second plate 320 is individually rotated, and when the connection plate 370 is provided, the rotation of the first plate 310 and the second plate 320 is interlocked.

The connection plate 370 connects the first operation protrusion 311 and the second operation protrusion 321, and a first connection slot 371 and a second connection slot 372 are formed. The first connection slot 371 allows the first operating protrusion 311 to slide in the left and right directions, and the second connection slot 372 allows the second operating protrusion 321 to slide in the left and right directions. To help. That is, the connection plate 370 is formed so as to be spaced apart in the vertical direction, but there is no space in the vertical direction in the state coupled to the first operation projection 311 and the second operation projection 321.

As the first plate 310 and the second plate 320 rotate based on the central plate 330 by the action of an external force, the first actuating protrusion 311 and the second actuating protrusion 321 are rotated. The first operation slot 331 and the second operation slot 332 is moved downward, the first reciprocating protrusion 312 and the second reciprocating protrusion 322 is the first reciprocating slot 333 and the first The first operation protrusion 311 and the second operation protrusion 321 together with the first operation slot 331 by the connecting plate 370 is moved in the outward direction of the second reciprocating slot 334. Sliding movement along the second operation slot (332), and also sliding movement in the outward direction of the first connection slot 371 and the second connection slot (372).

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, in this case, the first elastic body 340 and the second elastic body 350 are elastically deformed in the direction in which the elastic force is increased the most, and even if elastically deformed, It is deformed at spaced locations so as not to overlap the path.

When the first actuating protrusion 311 and the second actuating protrusion 321 do not exceed an intermediate point between the first actuating slot 331 and the second actuating slot 332, the first elastic body 340 and The elastic force of the second elastic member 350 is returned to the unfolded state, and when it exceeds the intermediate point, it is converted into the folded state.

9 shows 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 ends of the first actuating slot 331 and the second actuating slot 332, and the first reciprocating protrusion 312. And the second reciprocating protrusion 322 are positioned inside the first reciprocating slot 333 and the second reciprocating slot 334. Further, the first plate 310 and the second plate 320 are respectively: It is a state that is elastically supported by the first elastic body 340 and the second elastic body 350, the external force does not act to the extent that can overcome the elastic force of the first elastic body 340 and the second elastic body 350 If not, this state is also maintained.

As such, the first elastic body 340 and the second elastic body 350 are located at the same point in the unfolded state and the folded state, and the first reciprocating protrusion 312 and the second reciprocating protrusion 322 are moved back and forth. By being coupled to), the space in which the first elastic body 340 and the second elastic body 350 are elastically deformed can be minimized and strong elastic force can be exhibited.

In the intermediate state, the first plate 310 and the first body 100 are maintained in the shape of FIG. 7 while the second plate 320 and the second body 200 are shown in FIG. 9. It may be understood as a modified state or vice versa.
