Hereinafter, the operation of the mobile phone hinge module of the present embodiment according to the above configuration will be described in detail.

6 shows a state in which the sliding body 14 is completely open with respect to the main body 12, and FIG. 8 shows a state in which the sliding body 14 covers the main body 12, and FIG. 8 is a view showing a state at an intermediate point moved to the state of FIG.

As shown in FIG. 6, in the state in which the sliding main body 14 is opened with respect to the main main body 12, the first and second springs 700 and 800 are stretched to the maximum, and the first and second moving plates 300 and 400 are formed. 1, 2 spaced apart from the maximum.

One side of the first movable plate 300 is rotatably coupled to the second pin 41 of the movable plate 40, and one side of the second movable plate 400 is the first pin of the fixed plate 30. 31) is rotatably coupled. As shown in FIG. 6, the hinge module is inclined at an angle with respect to the main body 12, and in the state in which the slide body 14 is open, the second pin 41 is connected to the first pin 31. It is located above.

Subsequently, when the sliding body 14 is moved downward, the positions of the first pin 31 and the second pin 41 are closer to each other. The first moving plate 300 approaches the first coupling portion 210 along the first guide bar 140, and the first spring 700 is compressed. In addition, the second moving plate 400 approaches the second coupling part 220 along the second guide bar 150, and the second spring 800 is compressed. That is, the first moving plate 300 and the second moving plate 400 approach each other.

In this case, as the first and second moving plates 300 and 400 are close to the first and second coupling parts 210 and 220, the first and second guide pins 500 and 600 may open the first and second pin insertion holes 211 and 221. Exposed through.

When the second pin 41 of the moving plate 40 is moved below the first pin 31, the first and second springs 700 and 800 are expanded and restored again. The first and second moving plates 300 and 400 are spaced apart from the first and second coupling parts 210 and 220 by the restoring force, and the slide main body 14 slides downward with respect to the main main body 12, thereby causing the keypad of the main main body 12 to be moved. 12a is covered.

In this case, the first and second stoppers 141 and 151 inserted into the first and second stopper grooves 350 and 450 of the first and second moving plates 300 and 400 may be formed by the first and second moving plates 300 and 400. To prevent it from leaving the bars 140 and 150.

Through the above process, the slide body 14 closes the main body 12, and through the reverse process of the above process, the slide body 14 opens the main body 12.

In the mobile phone hinge module according to the embodiment of the present invention operating by the above-described configuration, the guide frame 100 is formed of a metal foil to improve the strength. Therefore, even if the slide main body 14 repeatedly slides with respect to the main body 12, it prevents damage to the mobile phone hinge module and extends its service life.

In addition, the mobile phone hinge module according to an embodiment of the present invention, by the support body 200 is coupled to the guide frame 100, provides an effect of absorbing the vibration shock generated when sliding. The first and second springs 700 and 800 repeatedly generate compression and expansion to generate vibration in the mobile phone hinge module, and the vibration is absorbed by the support body 200 coupled to the guide frame 100. Therefore, the vibration shock that is unnecessarily transmitted to the mobile phone is alleviated to prevent the trouble of the mobile phone in advance.

In addition, the mobile phone hinge module according to an embodiment of the present invention provides an effect of preventing distortion of the hinge module by the pressing force applied to the sliding body 14. 9 and 10, the distortion prevention effect will be described in detail.

9 is a plan view of the mobile phone hinge module according to the embodiment of the present invention, and schematically shows the component force of the force when a pressing force F for opening the sliding body 14 is applied.

The pressing force F is applied in a direction perpendicular to the rotation center axis L1 connecting the point P1 to which the second pin 41 is coupled and the point P2 to which the first pin 31 is coupled. The rotation force F1 is decomposed into F2 applied in the direction of the rotation center axis L1. F1 is a force for rotating the mobile phone hinge module, a part of the F2 is used to compress the first and second springs 700,800.

That is, since the direction L2 in which the rotational center axis L1 and the first and second springs 700 and 800 are compressed are inclined by an angle, the force F for compressing the first and second springs 700 and 800 in the L2 direction. ') Is given by' F2cosα '.

And, as shown in Figure 10, the fixed plate 30 and the movable plate 40 are spaced apart in the vertical direction so that the hinge module is coupled to the oblique.

Assuming that the hinge module according to the present embodiment is inclined with the moving plate 40 by β angle, the force F4 for substantially compressing the first spring 700 is given by 'F2cosαcosβ' and the remaining components (F3) is given by 'F2cosαsinβ'.

In addition, as shown in FIG. 10, the force F5 for substantially compressing the second spring 800 is a reaction force of the F4, the magnitude of which is equal to F5, and the direction is opposite, and the remaining component force F6 is' F2cosαsinβ ', which is the same size as F3, with opposite reversal.

Thus, F3 generates torque to rotate the point P1 of FIG. 9 in the upward direction, and F6 generates torque to rotate the point P2 of FIG. 9 in the downward direction. Therefore, the point P1 is forced upward and the point P2 is forced downward and is twisted.

However, in the mobile phone hinge module according to the embodiment of the present invention, the guide frame 100 is formed of a thin metal plate to cushion the force while the guide frame 100 itself is elastically deformed during the twisting action by F3 and F6, F3 When F6 is removed and restored, the mobile phone hinge module is prevented from being twisted.

In addition, the mobile phone hinge module according to an embodiment of the present invention, to prevent the bending of the guide frame 100 in advance. As shown in Fig. 9, the component F '(size: F2sin?) Of F2 acts on the point P1, and the force equal to the size F " Therefore, a force acting to deflect the guide frame 100 into a "to" shape acts. Since the thin guide frame 100 employed in the mobile phone hinge module according to the present invention is formed of metal, it provides an effect of preventing the bending of the guide frame 100 in advance.

On the other hand, Figure 11 shows a mobile phone hinge module according to another embodiment of the present invention.

Referring to FIG. 11, the mobile phone hinge module according to the present embodiment further includes a first rotating plate 390 and a second rotating plate 490.

The first rotating plate 390 is rotatably coupled to one end of the first moving plate 300 by a first coupling pin 391, and the second rotating plate 490 is connected to the second moving plate ( One end of the 400 is rotatably coupled by the second coupling pin 491. The first pivot plate 390 is rotatably coupled to the second pin 41 of the movable plate 40, and the second pivot plate 490 is the first pin 31 of the fixed plate 30. ) Is rotatably coupled.

In the mobile phone hinge module according to the present embodiment, the rest of the components except for the first and second pivoting plates 390 and 490 are the same as those of the embodiment, and thus detailed description thereof will be omitted.

12 schematically illustrates a mounting state of a mobile phone hinge module according to the present embodiment. As shown in FIG. 12, by including the first rotating plate 390 and the second rotating plate 490, the hinge module is stably coupled by increasing the contact area between the moving plate 40 and the fixed plate 30. Will be. By the pressing force repeatedly applied to open and close the sliding body 14, the portion where the first pin 31 is coupled to the second moving plate 400 and the second pin 41 is the first moving plate 300 It prevents the part joined to the breakage in advance.
