The elasticity of the second body 120 can be obtained by rotating the second body 120 in the opening direction.

On the other hand, as shown in Figure 3, the opening and closing device 200 including the hinge connection portion 210 is disposed in a state inclined toward the second body 120 when the second body 120 is closed state As described later, the second body 120 is easily pushed from the upper end side of the terminal to slide downward.

In addition, the thickness of the first body 110 may be formed to become thinner toward the top in the vicinity of the hinge connecting portion 210 to provide a moving space of the second hinge shaft 222.

In addition, the length of the opening and closing device 200 is smaller than the sum of the thicknesses of the first body 110 and the second body 120 so that the first body 110 and the second body 120 can be rotated 360 degrees. It may not be formed.

As shown in FIG. 7, in the second elastic force providing unit 270, the second body 120 connected to the opening and closing device 200 by the rotation of the opening and closing device 200 is 360 with respect to the first body 110. As to provide an elastic force to the opening and closing device 200 in the process of rotating, the housing 271 and the fixed cam 276, a movable cam 273 having a function similar to the first elastic force providing unit 250 described above ), And a spring 280 or the like.

In this case, the camp profiles 274 and 275 of the movable cam 273 may be formed to have a different radius around the cam shaft 277, and the camp profiles 274 and 275 may be doubled. It is possible to have a shape corresponding to the camshaft 277 as the center.

As shown in FIG. 13 in which the movable cam 273 is unfolded, the camp profiles 274 and 275 of the movable cam 273 are fixed cams 276 while the second body 120 slides. It includes a section (D2) formed concave from the fixed cam 276 so that the distance from the).

Accordingly, while the second body 120 is slid from the closed position, the spring 280 is compressed while the distance from the fixed cam 276 of the movable cam 273 is farther away, and the slide of the second body 120 is moved. After the movement, the contact position of the fixed cam 276 of the movable cam 273 to the camp profiles 278 and 279 by the spring 280 is moved again toward the concave side.

As shown in FIG. 4 and FIG. 8, the stopper device 240 is connected to the second hinge shaft 222 connected to the second body 120 to be rotated together by the rotation of the second body 120. A cam 241 and an actuating rod 243 disposed to be movable in contact with the cam 241 and providing a locking surface 243a to the cam 120 to stop the second body 120 are provided.

At least one projection 242 is formed on the outer circumference of the cam 241 (if the projection is two or more, the number of stopping points can be provided), and the forward and reverse rotations are performed by the operating rod 243. It acts as a stopper for all.

In order to guide the reciprocating motion of the actuating rod 243, a guide member 244 may be mounted on the lower connecting member 212 around the actuating rod 243, and the actuating rod 243 is an outer circumferential surface of the cam 241. A spring 246 for applying an elastic force to the actuating rod 243 to abut against the actuating rod 243 is installed between the actuating rod 243 and the lower connection member 212.

In addition, the engaging surfaces 243a and 242a of the operating rod 243 and the cam 241 are formed to be inclined to have the same inclination angle in the same direction, so that the rotation of the second body 120 is primarily performed when they are in contact with each other. When the cam 241 is further rotated in the advancing direction by applying a force, the engaging surface 243a of the cam 241 pushes the engaging surface 243a of the operating rod 243 to retract the operating rod 243. I can do it.

As shown in FIG. 8, the lower connecting member 212 has a jaw 249 to stop the rotation of the cam 241 when the engaging surface 242a of the cam 241 passes the operating rod 243. It is prepared. However, the jaw may be formed on the operation rod 243 instead of the lower connection member 212 to achieve the same function.

Hereinafter, the operation of the portable terminal by the above configuration will be described.

3 is a state in which the second body 120 is closed to the first body 110. In this case, the first elastic force providing unit 250 has a contact position between the fixed cam 256 and the movable cam 253. It is set to correspond to ① at 13.

When the second body 120 is pushed downward with respect to the first body 110, as illustrated in FIG. 9, the opening and closing device 200 is rotated with respect to the first body 110 and at the same time, the second body ( 120 is rotated with respect to the opening and closing device 200, respectively, so that the second body 120 slides downward with respect to the first body (110).

At this time, the fixed cam 256 and the movable cam 253 of the first elastic force providing unit 250 is in contact with the number ② above the vertex of the convex section (D1) in FIG. Then, the fixed cam 276 and the movable cam 273 of the second elastic force providing unit 270, as shown in Figure 14, between the fixed cam 276 and the movable cam 273 at the initial position ① ' The contact is made at ② 'which is far away.

In this state, when the force that pushes the second body 120 downward is removed, in the first elastic force providing unit 250, the fixed cam 256 by the elasticity of the spring 260 by itself of the movable cam 253 The contact position is changed to a place corresponding to ② of FIG. 13 by moving along the downward slope of the camp profiles 254 and 255. Therefore, the fixed cam 256 is twisted with respect to the movable cam 253, whereby the second body 120 is opened to rotate.

As the second body 120 is rotated, the state in the stopper device 240 is as shown in FIG. 8, when the second body 120 is rotated, the engaging surface 242a of the cam 241 is operated by the rod. The second body 120 is once stopped by reaching the engaging surface 243a of the 243.

If the position and shape of the cam 241 and the operating rod 243 is set so that the opening angle of the second body 120 up to about 150 degrees, it is possible to make use of a state where a call can be made.

On the other hand, when the force pushing the second body 120 downward is removed, the second elastic force providing unit 270, as shown in Figure 14, by the restoring force of the spring 280, as shown in Figure 14, the movable cam 276 The contact position with the cam 273 is moved downward again along the camp profiles 274 and 275 of the movable cam 273 to return to the position ③ ′ which is the same as the initial position. Accordingly, as shown in FIG. 10, the rotation angle of the opening and closing device 200 with respect to the first body 110 is the same as that of FIG. 3 in which the second body 120 is closed with respect to the first body 110.

That is, the second elastic force providing unit 270 is to open the distance to the first body 110 of the second body 120 while the second body 120 is rotated to open. Therefore, the mechanism of the first elastic force providing unit 250 by rotating the second body 120 by the second elastic force providing unit 270 is not limited.

If the second body 120 is further rotated in the state of FIG. 10, as shown in FIG. 11, the second body 120 is rotated about 180 degrees with respect to the first body 110. In this case, the fixed cam 256 of the first elastic force providing unit 250 is in contact with the movable cam 253 in the place corresponding to ④ of FIG.

In this case, as shown in FIG. 14, the second elastic force providing unit 270 contacts the fixed cam 276 at a position corresponding to ④ 'without changing a relative position with respect to the movable cam 273.

In addition, in the case of the stopping device 240, the protrusion 242 of the cam 241 rotates while compressing the operation rod 243 and the spring 246 connected thereto, and the protrusion 242 of the operation rod 243. As soon as the vertex passes, the actuating rod 243 is pushed by the restoring force of the spring 246.

As a result, the actuation rod 243 advances again, thereby preventing the opposite rotation of the cam 241. In addition, since the protrusion 242 is also in contact with the jaw 249, rotation in the direction of travel no longer occurs.

If the position and shape of the cam 241, the operating rod 243, and the jaw 249 are set so that the opening angle of the second body 120 at this time is about 180 degrees, the first body 110 is held in the state of being held. The display 121 of the second body 120 may be used in a state in which the subject may be easily photographed.

When the second body 120 is further rotated in the state of FIG. 11, the second body 120 is no longer rotated along the second hinge shaft 221 by the stopping device 240, and the second body is not. The 120 and the opening and closing device 200 are integrally rotated along the first hinge shaft 221 connected to the first body 110.

As shown in FIG. 13, when the rotation angle of the second body 120 is 360 degrees, the contact position between the fixed cam 256 and the movable cam 253 of the first elastic force providing unit 250 is ⑤ such as ④. Will be at position. At this time, the fixed cam 276 of the second elastic force providing unit 270 is rotated 180 degrees with respect to the movable cam 273 is moved to ⑤ 'of FIG.

In this case, the second body 120 faces the rear surface of the first body 110 to manipulate only the inner display 121 or through the video (eg, VOD) or broadcast (eg, DMB). ) Can be utilized in an easy state to appreciate.

As described above, according to the portable terminal of the present invention, when the second body is pushed in the longitudinal direction by an opening and closing device installed between the first body and the second body, the second body is automatically opened and rotated so that the second body is removed. The operation to open for one body is concise and easy for the user to learn.

In addition, according to the present invention, two hinge shafts are provided so that the opening angle of the second body can be easily applied to a device having a wide range of 360 degrees, and the opening and closing performance is excellent.

As described above with reference to the drawings illustrating a portable terminal according to the present invention, the present invention is not limited by the embodiments and drawings disclosed herein, but to those skilled in the art within the scope of the technical idea of the present invention Various modifications can be made by this.
