Embodiment approach

[0041] Figure 7 Shown is a swivel hinge according to another embodiment of the present invention.

[0042] Such as Figure 7 As shown in (a), the first and second lower magnets 221 and 222 are arranged at equal angles (eg, 45°) to each other around the center. In other words, the first lower magnets 221 are arranged at equal angles (such as 90°) to each other, and the second lower magnets 222 are arranged at equal angles (such as 90°) to each other. The first and second lower magnets 221 and 222 are alternately arranged. On the other hand, the first and second upper magnets 231 and 232 disposed on the rotating plate 230 are arranged at equiangular angles (eg, 90°) to each other around the center of the rotating plate 230 . As described above, the first and second lower magnets 221 and 222 have different magnetic properties from each other, the first upper magnet 231 has the same magnetic properties as the first lower magnet 221 , and the second upper magnet 232 and the sec...

Abstract

A swing hinge apparatus of a cellular phone according to the present invention includes: a plurality of first and second lower magnets having polarities different from each other; a lower casing, the first and second lower magnets being respectively inserted into one surface of the lower casing; a plurality of first and second upper magnets having the same polarities as the first and second lower magnets respectively; and a rotating plate provided over the lower casing, where the first and second upper magnets are respectively inserted into one surface thereof facing the lower casing.

Description

technical field [0001] The present invention relates to a rotary hinge device for a portable phone, and more particularly, to a rotary hinge device for a portable phone using magnetic force. Background technique [0002] Generally, portable wireless terminals include bar type, flip type, flip up type, folder type, slide type or landscape type terminals. The types of portable terminals are constantly changing as the times in which terminals are used change. [0003] For a folder-type terminal, the upper body and the lower body of the terminal are connected to each other through a shaft, and the lower body is opened or closed by rotating the upper body around the shaft. In the panorama type terminal, by turning the shaft, the display unit is rotated horizontally, or the display unit itself is rotated horizontally. [0004] On the other hand, there is a slide component that can provide a panorama function by vertically / horizontally moving a slider of the screen, so that the s...
