Description

Slide hinge module having torsion spring

The present invention relates to a slide hinge module having a torsion spring, and more particularly to a slide hinge module having a multiple torsion spring.

As the spread of portable terminals gradually expands, terminals having various functions and various designs are being developed. Recently, a folder type and a slide type have become mainstream as portable terminals.

In particular, the slide-type portable terminal is provided with a slide hinge for sliding movement between the main body having a keypad and the cover provided with the LCD screen, a number of patents and utility models for the structure of the slide hinge is registered or It is open.

For example, in Patent Application No. 10-2007-0042796, 'Opening Slide Hinge' provides one end of an elastic coupling part for fixing one end of the elastic body and the other end is a plate-shaped connecting slide having a rotatable coupling structure with the device. ; And a torsion spring having a concentric circle extending from the center on the same plane, one end of which is mounted to the elastic coupling portion of the connection slide portion and the other end of which has a rotatable coupling structure with the device. The slide hinge is characterized in that it is formed in a structure that does not exceed the height of the torsion elastic body.

In addition, a plate-shaped connecting slide having an elastic coupling portion for fixing one end of the elastic body on both ends; And two torsion elastomers each having a concentric circle extending from the center on the same plane, one end of which is respectively mounted to the elastic coupling portions of both ends of the connecting slide portion and the other end of which has a rotatable coupling structure with the device. The elastic coupling portion has been described for the slide hinge, characterized in that formed in a structure that does not exceed the height of the torsion elastic body.

However, in the case of the 'slide hinge' and the torsional elastic body mounted on the general slide type portable terminal, the torsion spring is composed of a single torsion spring. Increasing the distance, and also the proportion of the load acting on the torsion spring is proportionately increased, the life of the torsion spring is shortened, which has a problem that leads to deterioration of the quality of the portable terminal.

An object of the present invention is to solve the above problems, generally by replacing the torsion spring mounted on the slide hinge module with multiple torsion springs, the number of operation of the slide type terminal compared to the case where a single torsion spring is mounted It is to provide a slide hinge module having a torsion spring that can be more sure.

In order to achieve the above object, a slide hinge module having a torsion spring according to the present invention is mounted between a main body and a slide portion of a slide type terminal, and a slide hinge module having a torsion spring for providing an operating force when the slide portion is slid. The torsion spring may be a multiple torsion spring in which two or more torsion springs are integrally coupled.

The slide hinge module having a torsion spring according to the present invention is mounted between a main body and a slide unit of a slide type terminal, the slide hinge module having a torsion spring for providing an operating force during sliding movement of the slide unit. The module includes a housing having a fitting portion to which the fixing bar formed at the center of the torsion spring is inserted and fixed, wherein the torsion spring is a multiple torsion spring in which two or more torsion springs are integrally coupled.

As can be clearly seen from the above description, according to the slide hinge module having a torsion spring according to the present invention, a conventional single torsion spring is generally replaced by replacing a single torsion spring mounted on the slide hinge module of a slide type terminal with multiple torsion springs. Increasing the number of operations of the slide hinge module to guarantee it has the effect of improving the quality of the slide type terminal.

First, the present invention is a slide hinge module having a torsion spring mounted between the main body and the slide portion of the slide type terminal to provide an actuation force when the sliding portion of the slide movement, the torsion spring is a plurality of torsion springs are integrally coupled multiple It characterized in that it comprises a torsion spring, hereinafter with reference to the accompanying drawings will be described in detail a preferred embodiment of the multiple torsion spring and the slide hinge module equipped with it.

Exam conditions Spring condition Single torsion spring Multiple Torsion Springs Serial structure Parallel structure
A
Assembly pitch 18 mm Φ9.0 outside diameter
Inner diameter φ2.5
Wire diameter 0.3 * 0.5 (rolled)
Number of turns to fit 120,000 times
pass 120,000 times
pass 120,000 times
pass Stroke 35 mm Working force 240gf
B
Assembly pitch 18 mm 80,000 times

pass 120,000 times
pass Stroke 40 mm Working force 250gf
C
Assembly pitch 18 mm 60,000 times
fail 120,000 times
pass 120,000 times
pass Stroke 45 mm Working force 260gf

Referring to the experimental data shown in the above table, when the operating stroke (sliding movement amount between the main body and the slide part of the slide type terminal) is 35 mm and the operating force of 240 gf is applied at the same assembly pitch, even a single torsion spring is usually produced by a manufacturer. Meets the standards guaranteed by 120,000 sliding round trips.

However, when the stroke is increased (40mm, 45mm) and the applied force is increased (250gf, 260gf), the use of a single torsion spring dramatically reduces the number of sliding reciprocations possible, while the multiple torsion springs of the present invention are used. It can be seen that the usual guarantee criteria (120,000 sliding round trips) are satisfied.
