One mounting hole 362 is provided at each end of the driven member 36, and these two mounting holes 362 are parallel to each other.

Hereinafter, the assembly procedure of the mobile phone 100 according to the present invention will be described in detail.

First, the first mounting cylinder 332 of the first rotary support member 33 is placed between two second mounting cylinders 342 of the second rotary support member 34 on the same straight line. Install it at the location. Then, the fixing portion 352 of the hinge member 35 is fixed in the second mounting cylinder 342 of the second rotating support member 34, while the rotating portion 354 of the hinge member 35 is fixed. Is fixed in the first mounting barrel 332 of the first rotary support member 33. Next, the two first mounting arms 334 of the first rotary support member 33 are respectively positioned between the two projections 312 at both ends of the fixed plate 31, and their rotation holes 3332 and 3122. ) Is installed so that the shaft center is located on the same straight line, and then the rotational shaft 40 is inserted into the first rotational hole 3122 and the second rotational hole 3332, thereby providing the first rotational support member 33. Is rotatably coupled to the fixing plate (31). Subsequently, one end of the driven member 36 is positioned in the mounting groove 314 of the fixed plate 31 such that the axis of the second rotating hole 3322 and the mounting hole 362 are on the same straight line. After installation, the one end of the driven member 36 is inserted by inserting the rotary shaft 40 into the second rotation hole 3314 of the mounting groove 314 and the mounting hole 362 of the driven member 36. It is rotatably coupled to the fixing plate (31).

Next, the ends of the two second mounting arms 346 of the second rotary support member 34 are respectively rotated in the two first through holes 322 of the mounting plate 32 in the rotating holes 3652. And 3222 in such a way that the shaft center is positioned on the same straight line, and then in the third rotation hole 3222 of the mounting plate 32 and the sixth rotation hole 3442 of the second rotation support member 34. By inserting the rotary shaft 40, the second rotary support member 34 is rotatably coupled to the mounting plate (32). At this time, the first rotary support member 33 is positioned between the two second mounting arms 346.

Subsequently, the other end of the driven member 36 is positioned in a second straight groove 324 of the mounting plate 32 in a straight line with the same axial center of the mounting hole 362 and the fourth rotating hole 3324. And the rotary shaft 40 is inserted into the fourth rotating hole 3324 of the mounting plate 32 and the mounting hole 362 of the driven member 36, thereby providing the driven member 36. The other end of the) is rotatably coupled to the mounting plate (32).

Finally, the fixing plate 31 is mounted in the mounting recess 124 of the operation side case 10, and then the fixing plate 31 is fixed to the operation side case 10 using a screw or the like. Similarly, the mounting plate 32 is fixed in the receiving recess 22 of the display side case 20 using a screw or the like. In this way, the assembly of the mobile phone 100 is completed.

Referring to FIG. 5, when the mobile phone 100 is opened, one end close to the operation button 122 of the display side case 20 is pushed along the width direction of the operation side case 10. In this case, both ends of the driven member 36 are rotated about the rotary shaft 40 in the mounting groove 314 and the rotary shaft 40 in the second through groove 324, respectively, and are inclined at the same time. Therefore, the second rotary support member 34 is rotated relative to the first rotary support member 33, and at the same time, the first rotary support member 33 is connected to the second rotary support member 34. In conjunction with the operation side case 10 is inclined to stand up. In this process, the rotating part 354 of the hinge member 35 fixed in the first mounting cylinder 332 of the first rotary support member 33 is the second of the second rotary support member 34. It is rotated relative to the fixing portion 352 of the hinge member 35 fixed in the mounting cylinder 342.

The rotating part 354 of the hinge member 35 has a predetermined rotational position with respect to the fixed part 352 of the hinge member 35. When the rotating part 354 exceeds the preset rotational position, the rotating part 354 is automatically rotated with respect to the fixing part 352 under the action of the driving part of the hinge member 35. That is, when the display side case 20 is further pushed so that the rotation part 354 of the hinge member 35 exceeds the preset rotational position, the second rotation support member 34 may be formed of the first rotation support member ( 33) and automatically rotates with the driven member 36 relative to the operation side case 10 in conjunction with it. When one end contacting the operation side case 10 of the display side case 20 abuts on the fixing part 128 of the operation side case 10, the mobile phone 100 is inclined to be completely opened to be suitable for the user. Provide audiovisual

In addition, the display side case 20 and the mounting plate 32 may be integrally molded, and the operation side case 10 and the fixing plate 31 may be integrally molded.

In addition, the number of the second mounting cylinder 342 and the hinge member 35 of the second rotary support member 34 is not limited.

In addition, the fixing part 352 of the hinge member 35 is fixed in the first mounting cylinder 332 of the first rotary support member 33, and the rotating part 354 of the hinge member 35 is fixed to the first mounting cylinder 332. The second mounting cylinder 342 of the two-rotation support member 34 may be fixed.

In the present invention, the tilting mechanism 30 includes a first rotary support member 33 and a second rotary support member 34 rotatably coupled by a hinge member 35, and a driven member 36. do. The display side case 20 may be inclined with respect to the operation side case 10 by the tilting mechanism 30.
