The present invention relates to a complex hinge device and to a portable terminal including the complex hinge device. In the portable terminal including the complex hinge device, lower and upper units, each of which includes a touch-type display part on the front surface thereof, are provided, and the upper and lower units are coupled together using the complex hinge device as a medium. Thus, the upper unit may be slidably rotated with respect to the lower unit. Further, the touch-type display parts may be operated in a smartphone mode, a notebook mode, and a tablet PC mode according to the operating mode of the portable terminal, so as to satisfy the needs of the user. For this purpose, the portable terminal including the complex hinge device includes: a biaxial hinge unit rotatably connected to one end of each of the two side surfaces of the upper and lower units, such that the upper unit is rotatable with respect to the lower unit; a rotatable connecting link bar having one end of each of the other side surfaces of the upper and lower units in which the other end of the biaxial hinge unit is inserted and fixed; and a hinge unit, one end of which is inserted and fixed in the central portion of the inner surface of the connecting link bar, and the other end of which is inserted and fixed in a second receiving groove formed in each of the two side surfaces of the upper unit so as to exert compressive force onto the upper unit when the upper unit is rotated at an angle of about 180 degrees with respect to the connecting link bar. Here, the biaxial hinge unit, the connecting link bar, and the hinge unit connect the upper and lower units together such that a cable for supplying power and reading/writing information is electrically connected. |
