Description

SLIDE HINGE DEVICE {SLIDE HINGE DEVICE}

The present invention relates to a personal handheld terminal, and more particularly, to a hinge device mounted on the personal handheld terminal for sliding movement between each terminal body.

Mobile phones may be generally classified into a flip type, a folder type, and a sliding type according to their appearance or operation.

Among them, the sliding type mobile phone is arranged to overlap two sliding bodies, and the display unit and the key input unit are disposed in the same direction on each of the sliding bodies. In general, the sliding type mobile phone may expose the display unit or the key input unit that is covered by the rear side by relatively moving the sliding body of the front. For example, there is a slide-type mobile phone that can push up the front sliding body to expose a key input unit formed on the front of the sliding body in the rear. In addition, as another example, there is a mobile phone that can expose the display formed on the front of the sliding body of the rear by moving the sliding body of the front in which the key input unit is formed.

The slide-type mobile phone includes a sliding body overlapping up and down, and a sliding hinge device for connecting both bodies is interposed between the sliding bodies to interconnect the sliding bodies, and may assist sliding of each other. .

1 is a perspective view for explaining a conventional sliding device. For reference, the slide hinge device of Figure 1 is disclosed in Korean Patent Publication No. 10-453644.

Referring to FIG. 1, the conventional sliding device 100 includes a guide rail member 110, a slide member 120 sliding on the guide rail member 110, and first and second aids of sliding of the slide member 120. Torsion springs (130, 140).

Holes are formed in each of the rectangular plates 112 slightly adjacent to each other near the edges of the rectangular plate 112, and holes are formed in each of the arms 132a and the second torsion springs of the first torsion spring 130. One arm 142a of 140 is pivotally inserted.

The slide hinge device 100 using the first and second torsion springs 130 and 140 can stably slide the sliding body. However, the operating sections of the first and second torsion springs 130 and 140 may cause friction with the sliding body to cause noise and reduce the feeling of slide. In addition, since the conventional fixing of the first and second torsion springs 130 and 140 is inserted into and fixed in the holes, the first and second torsion springs 130 and 140 may flow up and down, and the first and second torsion springs 130 and 140 may flow. When the torsion springs 130 and 140 flow, the first and second torsion springs 130 and 140 may come loose from the holes, thereby causing a defect in the product.

Accordingly, one object of the present invention for solving the above problems of the present invention is to provide a slide hinge device having a stable binding of the torsion spring and the slide hinge and having a good feeling of slide.

In addition, another object of the present invention is to provide a slide hinge device that minimizes the noise caused by the interference by minimizing the interference interval between the torsion spring and the slide hinge.

The first slide hinge portion formed in the first part protrudes toward the second part and includes a bent portion formed with a first spring hole in the center thereof. One end of the torsion spring is inserted into and fixed to the first spring hole formed at the center of the bent portion. The torsion spring which rotates along the periphery of the first spring hole of the fixing part minimizes the friction surface with the first slide hinge part by the fixing part, thereby reducing noise when the first and second parts slide. Provide a stable feeling of slide.

A second spring hole corresponding to the first spring hole is formed in the second slide hinge portion formed in the second part, and is engaged with the first slide hinge portion to guide the movement of the second part.

In addition, the first part may be provided with a protruding support portion protruding toward the second part, and the protruding support portion is formed at a predetermined interval around the first spring hole and the first spring hole, and the shapes thereof are circular arcs, circular and It may be formed in various shapes such as polygons. The torsion spring inserted and rotated in the first spring hole minimizes the friction surface with the first slide hinge portion by the protruding support portion, thereby reducing noise during the slide movement of the first and second parts and providing a stable feeling of slide. Can provide.

In addition, the rivet may be further provided in the first spring hole. At this time, the end portion of the torsion spring is rolled round to rotate in spaced gaps between the rivet and the first slide hinge. When the slides of the first and second parts are moved, the torsion springs, which have both ends coupled to the first spring hole and the second spring hole and rotate in rotation, can flow up and down, and the torsion springs are released from the first and second spring holes. Etc., but this is prevented by riveting.
