ROTARY TYPE HINGE DEVICE, PERSONAL PORTABLE DEVICE USING THE ROTARY TYPE HINGE DEVICE AND METHOD OF MANUFACTURING THE ROTARY TYPE HINGE DEVICE

摘要

The rotary hinge device is provided with a first through hole in a central portion, and has a first hinge selectively having one or a combination of first protrusions projecting inwardly by press working and first fixing grooves formed on the inner surface by press working. Located adjacent to the plate, the first hinge plate, and the second through hole is provided in the center portion, one of the second fixing groove corresponding to the first protrusion and the second protrusion corresponding to the first fixing groove by press working A second hinge plate optionally having a combination, and connected to the first hinge plate and the second hinge plate through the first and second through holes, to which a spring for providing elastic force is connected, the first and second hinges It is provided with a central bushing for the axis of rotation of the plate. In addition, a personal portable terminal can be manufactured using the rotary hinge device, and a method of manufacturing a rotary hinge device using a press working can be disclosed. Therefore, the manufacturing cost of the rotary hinge device can be reduced, and the thickness of the hinge device can be manufactured thinly.;Hinge plate, press processing, personal handheld terminal
