Description

Swing hinge module {SWING HINGE MODULE}

The present invention relates to a hinge module of a portable wireless terminal composed of a main body and a sub body flowing on the main body, and in particular, the sub body is configured to be rotatable in both directions about an axis perpendicular to the front of the terminal. A swing hinge module for convenience.

In recent years, portable wireless terminals, which have been widely distributed as necessities of life, have been released with various designs of terminals having more advanced functions and aesthetic functions to meet user's needs. The terminals have been developed from general bar type terminals to flip type terminals, flip up type terminals, folder type terminals, and the like. Terminals are mainstream. This is because the folder type terminal has enough space to adopt a wide LCD module (for example, a high definition color display device) as a display device.

On the other hand, in addition to the above-described folder type terminal, in order to meet various preferences of the user, slide terminals on which the sub-body slides in the longitudinal direction of the terminal to open and close are released.

In addition, a terminal has been released that is configured to rotate about an axis perpendicular to the front of the terminal on the main body. The terminal has a built-in hinge module different from a general folder type or a flip type, which will be referred to as a swing hinge module (or a vertical hinge module).

The swing hinge module includes a predetermined hinge housing, a hinge spring, a hinge cam, and a hinge shaft that are sequentially received in the hinge housing. The hinge shaft is provided with a predetermined hill portion, and a predetermined valley portion is formed in the hinge cam to fit the hill portion of the hinge shaft. Therefore, when the hinge shaft is rotated, the ridge portion of the hinge shaft is operated while retracting the valley portion of the hinge cam.

However, since the swing hinge module as described above is limited to the portion where the top and the valley of the hinge shaft are combined, the swing hinge module is rotated completely by 90 ° or more, and after the rotation, the eccentric moment is generated by the ridge and the valley. The operation is inconvenient. In addition, since the sub body is rotated only in one direction on the main body, a user who is operable with his right hand may be inconvenient to operate with his left.

SUMMARY OF THE INVENTION An object of the present invention is to provide a swing hinge module of a portable wireless terminal configured to rotate in both directions about an axis perpendicular to a front surface of a terminal.

Another object of the present invention is to provide a swing hinge module of a portable radio terminal, which is configured to be self-fixed without receiving an eccentric moment in a state where the sub body is rotated.

Another object of the present invention is to provide a swing hinge module of a portable wireless terminal that maximizes the ease of use for the user to easily open or close the terminal in both the right hand and the left hand.

As shown in Figs. 3 to 6, the hinge shaft 30 according to the present invention has two bone portions 31 and 32 on the fixed plate 30 '. The first bone portion 31 and the second bone portion 32 are formed to face each other, preferably have concentric circles, are formed on different circumference. Thus, each of the valleys 31 and 32 is different in size from each other. In addition, the first slide surface 311 is symmetrically formed upward from the first valley portion 31, and the second slide surface 313 symmetrically downward while making the maximum first inflection point 312 is symmetrically. Is formed. The second slide surface 313 converges to one point to form a first lowest point 315. Similarly, the third slide surface 321 is symmetrically upwardly formed in the second valley part 32, and the fourth slide surface 323 symmetrically downward while making the maximum second inflection point 322 is symmetrically. Is formed. The fourth slide surface 323 converges to one point to form a second lowest point 325. A predetermined restriction groove 36 having a predetermined length is formed at one side of the valleys 31 and 32, and a predetermined ball stopper (37 in FIG. 3) is provided on the restriction groove 36.

On the other hand, a guide groove (25 in FIG. 4) in which the ball stopper 37 may be seated is formed on a surface of the hinge housing 20 that contacts the fixing plate 30 ′ of the hinge shaft 30. The guide groove 25 extends in a circle along the edge of the hinge housing 20 end, but is not connected. That is, the groove is not formed as long as the restriction groove 36. Therefore, when the hinge shaft 30 rotates, the ball stopper 37 is guided along the guide groove 25 of the hinge housing 20, and as a result, the sub body of the terminal is rotated on the main body, but 180 ° It controls the further rotation within the rotation range of.

On the surface facing the hinge shaft 30 of the hinge cam 50, two mountain parts 51 and 52 which can be selectively engaged with the first bone portion 31 and the second bone portion 32; Is formed. The first mountain portion 31 and the second mountain portion 32 are also protrudingly installed on concentric circles, but are disposed on other circumferences. Of course, the two ridges 51 and 52 are different in size from each other so as to be applied to the valleys 31 and 32 having different sizes.

Furthermore, the first inflection point 312 and the second inflection point 322 of the hinge shaft 30 are formed at a position where the sub body of the terminal rotates to 180 ° by itself when passing through an angle of about 35 ° with the main body. do. In other words, when the sub body of the terminal passes through an angle of about 35 ° with the main body, the first and second mountain parts 51 and 52 of the hinge cam 50 are formed on the hinge shaft 30. It may be formed to ride over the first inflection point 312 and the second inflection point 322. Therefore, in order to perform such an operation, the first slide surface 311 of the hinge shaft 30 should be formed to have a larger inclination than the second slide surface 313. Similarly, the third slide surface 321 of the hinge shaft 30 should be formed such that the inclination is larger than that of the fourth slide surface 323. However, it is not limited thereto. The inflection points 312 and 322 can be modified according to the type, shape, and the like of the terminal.

FIG. 7B illustrates a state in which the sub body is rotated at an angle of about 35 ° on the main body as described above. In this case, the first mountain part 51 of the hinge cam 50 may have the first inflection point () of the hinge shaft 30. 312), and also the second mountain 52 is a time passing the second inflection point (322).

FIG. 7C shows that after the above-described operation, the first body 51 of the hinge cam 50 is seated at the first lowest point 315 of the hinge shaft 30 with the sub body rotated by 180 ° on the main body. At the same time, the second mountain portion 52 is also in a state of being seated at the second lowest point 325 of the hinge shaft 30. That is, since the mountain parts 51 and 52 face each other while being balanced at each of the lowest points 315 and 325, the shaking of the sub body due to the eccentric moment can be prevented.

On the other hand, each of the slide surface (311, 313, 321, 323) and the inflection point (312, 322) is formed symmetrically around the two valleys (31, 32) of the hinge shaft 30, the sub-body May be operated to rotate in both directions on the main body.
