In addition, the present invention is a first member formed to have a predetermined length, a second member formed in a shape corresponding to the first member and moved upward to open the front surface of the first member, the first member and the A mobile phone including a sliding device for slidably connecting a second member to each other, wherein the sliding device is formed to have a first slider rotatably installed on the first member and a predetermined length and is fixedly installed on the second member. And a second slider in which the first slider is slidably installed, disposed between the first slider and the second slider, one end of which is installed on the first slider, and the other end of which is installed on the second slider. 2 includes an elastic member to automatically move by a set distance when the member moves over a certain distance, When the second member is moved upwards and the front surface of the first member is opened, the second member is rotated so that the first member and the second member are obtuse with each other.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the mobile phone to which the sliding device according to the present invention is applied has a first member 10 formed to have a predetermined length and a shape corresponding to the first member 10, and thus the first member 10. The first member 10 and the second member 20 are slidably connected to each other through the sliding device 30, including the second member 20 that opens and closes the front surface of the front panel.

As shown in Fig. 2, the first member 10 includes a keypad 11 having numbers or symbols printed thereon for inputting various character information and a microphone having a microphone for converting sounds into electric signals. (12) is provided, and the second member (20) is provided with a display window (21) made of a liquid crystal panel or the like and a receiver (22) in which a speakerphone for converting sounds of electric signals is also incorporated.

In addition, in the mobile phone to which the present invention is applied, in order to allow the talker 12 of the first member 10 and the receiver 22 of the second member 20 to be adjacent to each other, the user's mouth and ear. When the front surface of the member 10 is opened, the first member 10 and the second member 20 are to be formed an obtuse angle, for this purpose, the sliding device 30 is the second member 20 upwards When the front surface of the first member 10 is opened by sliding, the second member 20 can be rotated at an angle.

As such, the sliding device 30 is slidably connected to the first member 10 and the second member 20 so that the first member 10 and the second member 20 can be opened at an obtuse angle. As shown in FIG. 3, a first slider 31 having a lower end rotatably installed on an upper portion of the front surface of the first member 10 and a predetermined length is fixed to the rear surface of the second member 20. The first slider 31 is slidably coupled to the second slider 32 and the first slider 31 is elastically supported on the first member 10 so that the front surface of the first member 10 may be opened. When the sliding device 30 and the second member 20 includes a finger unit 33 to rotate.

At this time, an external force is applied between the first slider 31 and the second slider 32 by the user so that the second member 20 can be automatically slid by a set distance after the second member 20 moves more than a predetermined distance. Member 34 is provided. In this embodiment, the elastic member 34 has a pair of torsion springs, one end of which is rotatably installed on the first slider 31 and the other end of which is rotatably installed on the second slider 32.

In addition, the first slider 31 is slidably accommodated at both ends of the second slider 32 on both sides of the first slider 31 so that the first slider 31 can be slidably coupled to the second slider 32. The rail part 31a is provided in concave shape, and the 2nd rail part 32a which is slidably accommodated in the 1st rail part 31a is provided in the both ends of the 2nd slider 32. As shown in FIG. In the present exemplary embodiment, the second rail part 32a has a rod-shaped member formed of a material having a relatively high strength and a smooth surface and having a low coefficient of friction, compared to a material forming the second slider 31. 31 are respectively provided on both sides, and the 2nd rail part 32a is formed.

In addition, the lower end of the first slider 31 protrudes toward the front side of the first member 10 so that the first slider 31 can be rotatably installed on the first member 10. The hinge part 31b is rotatably installed on the front surface of the upper side of the first member 10, and the front side of the first member 10 corresponds to the lower end of the second member 20 when the front surface of the first member 10 is opened. The rotary groove 13 is provided concave at the position. Therefore, in a state where the front surface of the first member 10 is closed by the second member 20, the rear surface of the second member 20 is entirely supported by the front surface of the first member 10. When the member 10 and the second member 20 are maintained in parallel with each other, but the second member 20 moves upwards and the front surface of the first member 10 is opened, the second member 20 Since the lower end is in a state capable of rotating through the rotation groove 13 provided in the first member 10, the second member 20 rotates by the elastic force of the finger unit 33 and the first member 10. The second member 20 is to form an obtuse angle.

The finger unit 33 is fixed to the first member 10 and moves forward and backward in the hinge portion 31b through the fixed cam 33a and the coil spring 33c which rotate together with the first member 10. It is installed so as to interact with the fixed cam 33a and includes a movable cam 33b for causing the sliding device 30 and the second member 20 to rotate about the hinge portion 31b. In addition, the movable cam 33b and the coil spring 33c are installed in the tangent unit 33 so that the fixed cam 33a and the movable cam 33b can be installed in a state of being supported with each other through the coil spring 33c. The holder 33d and one end accommodated therein are installed in the holder 33d, and the other end penetrates the coil spring 33c and the movable cam 33b, and is installed in the fixed cam 33a so that the fixed cam 33a is a holder ( It further comprises a camshaft 33e to be installed in 33d).

In this embodiment, the finger unit 33 may include the fixed cam 33a and the movable cam 33b to rotate the second member 20 according to the interaction between the fixed cam 33a and the movable cam 33b. However, the present invention is not limited thereto, and as illustrated in FIG. 4, the second member 20 may be rotated by providing the hinge unit 33 ′ formed by the torsion spring in the hinge portion 31b.

As described in detail above, the sliding device according to the present invention and the mobile phone having such a sliding device is capable of rotating the second member when the second member slides to open the front of the first member. There is an effect of enabling the second member to achieve an obtuse angle.
