Problems solved by technology

[0006] However, the above-mentioned flexible display device has the following problem. In order to solve the step difference in the length between the first plate and the second plate and the flexible display screen attached to the upper surface due to the bending of the hinge part, the first plate and the second plate have to be separated. Most of the area of ​​the rear part of the second plate is additionally equipped with a variable unit composed of a movable plate connected to the hinge member and a guide for guiding the forward and backward movement of the above-mentioned movable plate, thus causing the above-mentioned first plate and the second plate The thickness of the second plate becomes thicker and its structure becomes more complicated

Embodiment Construction

[0031] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0032] Such as Figure 1 to Figure 4 as shown,

[0033] The flexible hinge device 10 with a cam structure according to one embodiment of the present invention includes a hinge part 30, which is used to connect the flexible display screen 13 with flexibility to the first board 11 and the second board 12 attached to the upper surface, The folding action is performed in a bending or unfolding manner.

[0034] In the above-mentioned hinge part 30, a plurality of segmental parts 100 are connected by a linkage unit described later, so that the above-mentioned hinge part 30 can be bent or unfolded, and the segmental parts 100 at both ends of the plurality of segmental parts 100 are respectively connected to The first board 11 and the second board 12 are combined.

[0035] Such as Figure 8 and Figure 9 as shown,

[0036] The segmented com...

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 having a cam structure, and more specifically, to a flexible hinge device having a cam structure in which the first plate and the second plate can be reduced only by the structure of the hinge part without an additional variable unit. The step difference (step, step difference) in the length between the board and the flexible display screen can make the segmented parts of the hinge part bend on the same track. Background technique [0002] With the development of communication technology and the development of semiconductor and optical technology, portable terminal devices such as smart phones and tablet PCs, which can be connected to the Internet through the improvement of mobile phones, have exploded in popularity recently. Taking advantage of this, the entire living environment of human beings is changing, thereby brought about a major innovation in science and technology. In particular, a ta...
