Flexible hinge device having interlocking structure

Abstract

A flexible hinge device, according to the present invention, comprises: a first plate and a second plate to the top surfaces of which a flexible display screen having a bend is attached; and a hinge portion connecting the first plate and the second plate, and performing hinge operation by being folded or spread open. The hinge portion comprises: a cam portion in which a plurality of segment members are connected so that the hinge portion can be folded or spread open, wherein the first plate and the second plate are respectively connected to segment members positioned at two end portions, from among the plurality of segment members, and wherein the segment members are extended in the lengthwise direction; a fixed portion extendedly formed on the inside of and apart from two ends of the cam portion; a fixing member formed by having a head portion and a pin portion extending in the lengthwise direction from one end of the head portion; and a rotating portion extendedly formed on the outside of and apart from two ends of the fixed portion.

Description

technical field [0001] The present invention relates to a flexible hinge device with a linkage structure, and in more detail, relates to reducing the height between a flexible display screen and a first board and a second board with only a hinge structure without an additional variable unit It is a flexible hinge device with a linkage structure that can bend the joint parts of the hinge part in the same trajectory. Background technique [0002] In general, with the development of communication technology and semiconductor and optical technology, portable terminals such as smartphones and tablet computers that can connect to the Internet by improving mobile phones have enjoyed explosive popularity in recent years, and all living environments of people are taking advantage of these. Changes, thus bringing breakthroughs in science and technology. In particular, a tablet computer has the advantage of having a wide screen, but has the disadvantage of being inconvenient to carry ...

AI Technical Summary

Problems solved by technology

[0006] However, in order to solve the problem of a height difference between the first plate, the second plate and the flexible display screen attached to the upper surface of the first plate and the second plate due to the bending of the hinge portion, the above-mentioned flexible display device is in the above-mentioned Most of the area of ​​the rear part of the first plate and the second plate is additionally equipped with a variable unit, and the above-mentioned variable unit includes a movable plate connected to a hinge member and a guide member for guiding the forward and backward movement of the above-mentioned movable plate, so , there is a problem that the thickness of the above-mentioned first plate and the second plate becomes thicker, and the structure becomes complicated
