Tilt Up Modules for Mobile Devices

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt up module for a portable terminal, and more particularly, to a tilt up module for a portable terminal for slidably and tilting a mobile body of the portable terminal from a main body.

Recently, the portable terminal has been widely used due to its ease of portability and the convenience of free use anywhere.

Such portable terminals are generally classified into bar-type portable terminals, flip-type portable terminals, folder-type portable terminals, and slide-type sliding terminals according to their appearance and operation method. Can be.

Among these, the slide type portable terminal refers to a portable terminal in which a slide portion disposed to overlap with the main body portion is slidably opened and closed with respect to the main body portion.

For example, the slide unit may include a slide module connecting the main body unit and the slide unit so as to slide relative to the main body unit.

On the other hand, the recent slide-type portable terminal is tilted at a predetermined angle with respect to the main body portion after the slide portion is slid open along the width direction of the main body portion so that the game or movie can be conveniently viewed through the display of the slide portion. The function is being presented.

1 is a side view showing a tilting state of the conventional tiltable slide-type portable terminal, and this tiltable slide-type portable terminal is shown in detail in Korean Patent Laid-Open Publication No. 10-2010-0054430.

As shown in FIG. 1, the conventional tiltable slide-type portable terminal can be slidably moved on the tilting frame 31 and the tilting press 31 which are tiltably coupled around one end of the main body 10. It is provided to be made of a slide unit 20 to slide with respect to the main body portion 10.

The slide unit 20 is tilted in the main body unit 10 together with the tilting frame 31 after the slide opening is completed.

The conventional tiltable slide-type portable terminal does not have a separate member for restraining the rotation of the tilting frame 31 in a state before the slide opening of the slide portion 20, and the slide portion 20 and the main body portion ( 10) constrains the tilting of the tilting frame 31 by the interference therebetween.

However, if the tilting of the tilting frame 31 is restrained by the interference between the slide unit 20 and the main body unit 10, the slide unit 20 and the main body unit (a) when the slide unit 20 moves. Noise is generated by the friction between 10), shaking or vibration occurs in the slide unit 20, and the quality of the portable terminal is deteriorated.

The present invention is to solve the above problems, provided with a locking member for preventing the rotation of the angle adjustment member tilt up module for a mobile terminal that can prevent the generation of noise and vibration when moving the slider and improve the quality of the mobile terminal The purpose is to provide.

As described above, the first elastic member 460 is formed of a torsion spring to add rotational force to the locking member 400 in a direction of preventing rotation of the angle adjusting member 200, thereby allowing the second hook portion 420 to be rotated. In close contact with the first hook portion 213, the coupling force between the first hook portion 213 and the second hook portion 420 may be improved.

The stopper 510 is formed in a circular spherical shape and is mounted to slide along the mounting groove 121.

And the diameter of the stopper 510 is larger than the depth of the stop groove 212.

In addition, the stopper 510 is elastically supported in the direction of the stop groove 212 by the second elastic member 520.

The second elastic member 520 is made of a coil spring and is inserted into the mounting groove 121 to elastically support the stopper 510 in the direction of the stop groove 212.

One end of the stopper 510 is selectively inserted into the stop groove 212 by the rotation of the angle adjusting member 200 to stop the rotation of the angle adjusting member 200.

Of course, in some cases, the mounting groove 121 is formed in the angle adjusting member 200 so that the stopper 510 and the second elastic member 520 are mounted to the angle adjusting member 200, and the stop groove 212 may be formed in the fixing member 100.

The third elastic member 240 is made of a torsion spring, it is disposed to surround the first rotation shaft 230.

One end of the third elastic member 240 is mounted to the fixing member 100, and the other end is mounted to the angle adjusting member 200 so that the angle adjusting member 200 is in front of the fixing member 100. A rotational force is added to the angle adjusting member 200 so as to tilt.

As such, the third elastic member 240 is formed of a torsion spring, thereby adding rotational force to the angle adjusting member 200 to be inclined forward of the fixing member 100, thereby preventing rotation of the angle adjusting member 200. Simultaneously with the release, the angle adjusting member 200 automatically rotates a predetermined angle to proceed the non-stop sliding and tilting operation, thereby reducing the operating time of the tilt up module.

It describes the operation process of the tilt-up module for a mobile terminal according to an embodiment of the present invention made up of the above configuration.

7 illustrates a state in which the movable body 52 covers the upper part of the main body 51, and FIG. 8 illustrates a state in which the movable body 52 slides to open the upper part of the main body 51, and FIGS. 9 and 11 The movable body 52 is inclined inclined toward the front of the main body 51.

As shown in FIG. 7A, when the movable body 52 is disposed above the main body 51 and the upper part of the main body 51 is closed, the portable terminal tilt up module of the present invention is illustrated in FIG. 7. It is arranged in the same state as (b).

As shown in FIG. 7B, the fixing member 100 is disposed to be horizontal to the angle adjusting member 200, and the slider 300 is disposed to protrude forward of the guide member 220. .

The second hook portion 420 is coupled to the first hook portion 213, and the rotational force is applied to the locking member 400 in the counterclockwise direction by the first elastic member 460. The rotation of the angle adjusting member 200 is prevented.

In addition, the locking member 400 is rotated counterclockwise by the elastic force of the first elastic member 460 to return to the initial position.

The process from the sliding of the slider 300 to the rotation of the angle adjustment member 200 is made of a non-stop.

Thereafter, as shown in FIG. 10 (a), if the inclination angle of the movable body 52 is steeply steeped, the angle adjusting member 200 is further rotated counterclockwise as shown in FIG. 10 (b). The stopper 510 stops rotation when the stopper 510 is inserted into another stop groove 212 adjacent to the stop groove 212.

As such, the stopper 510 is selectively inserted into the stop groove 212 by the rotation of the angle adjusting member 200, so that the movable body 52 can be stopped by rotating at various angles with respect to the main body 51. There is an effect that can provide a variety of angles desired by the user.

As described above, the locking member 400 prevents the rotation of the angle adjusting member 200 and rotates by the movement of the slider 300 to release the rotation stop of the angle adjusting member 200. When the 300 is sliding, the angle adjusting member 200 is fixed by the locking member 400 to prevent noise and vibration, and after the sliding is completed, the rotation of the angle adjusting member 200 is stopped. It can be interlocked so that the tilt up module can be operated quickly.

The tilt-up module for the portable terminal of the present invention is not limited to the above-described embodiment, and may be variously modified and implemented within the allowable technical spirit of the present invention.

The present invention is to provide a locking member for preventing the rotation of the angle adjustment member in the tilt-up portable terminal to improve the quality of the portable terminal by reducing the noise and vibration that may occur when the slider is moved.
