Description

Mobile device
Technical Field
The utility model relates to an installation flexible display's inflection mobile device.
Background
Recently, foldable mobile devices are being developed for large screen displays.
As the kind of the foldable mobile device, there may be a fold-in manner and a fold-out manner.
The fold-in method is recently developed by samsung electronics, and is a method of mounting a flexible display on the inner sides of a first body part and a second body part and folding the flexible display with a small radius of curvature as in the case of folding paper with a folding line as a reference.
On the other hand, the folding-out method is shown by samsung electronics, china huashi and rouyu, and is a method in which the first body part and the second body part are folded and the flexible display is bent at a large radius of curvature on the outside.
In the fold-out manner, the flexible display and the first and second body portions are parallel to each other when unfolded, and thus have the same length. However, the folding line of the flexible display is located outside the center of rotation of the first body part and the center of rotation of the second body part. Therefore, when the first and second body portions are folded, the entire length of the flexible display located outside of the body portions may be insufficient.
As a countermeasure against this, if the flexible display is to be prevented from being torn when the first and second body portions are folded, the length of the first or second body portion should be made shorter, and therefore a complicated body portion length expansion structure may be required, which may be subject to design constraints, and since the expansion structure is provided at the folding portion, the folding portion cannot be completely attached and fixed to the expansion structure, which may cause the display to be severely tilted.
On the other hand, the folding method proposed by huashi or rouyu in china adopts a structure in which a flexible display, which becomes shorter in length than a main body portion when folded, is pulled in a direction of a folded portion of the main body portion. The telescopic structure of the body portion is provided at an end portion of the body portion on the opposite side to the folded portion. However, since the circumference of the body portion is increased when folded and the length of the flexible display is fixed, a portion not covered by the display is generated at the outside of the body portion and is visible to the naked eye, which may cause a decrease in the competitiveness in terms of usability or design.
The outward folding type has a common problem that, when the folding portion is provided with the telescopic structure, the folding portion not provided with the display is tightly attached to the fixing mechanism, so that the tilting between the folding portion of the main body portion and the display is increased.
In contrast, a common problem with the fold-in approach is that the radius of curvature of the folded portion of the display is small when folded, and thus the folded portion is severely wrinkled.
SUMMERY OF THE UTILITY MODEL
In order to prevent the fold from occurring at the folding portion, which is the essential problem of the fold-in method, the present invention adopts the fold-out method.
On the other hand, in the present invention, in order to prevent the occurrence of the warp, which is one of the problems of the fold-out method, from the root, the mechanism expansion structure is not disposed in the folded portion of the main body.
On the other hand, the present invention prevents the problem that the outer contour of the folded main body cannot be covered by the display, which is another problem of the fold-out method.

Detailed Description
The mobile device of the present invention will be described with reference to fig. 1 to 7.
The utility model discloses can include: forming a folder hinge unit 130; a first body part 110 rotating at one side of the chain unit 130; and a second body part 120 rotated at the other side of the hinge unit 130.
The flexible display 200 including the OLED, the LCD of the thin film may sequentially cover the first body part 110, the hinge unit 130, and the second body part 120. The utility model discloses a mobile device can fold flexible display 200 with the mode of external folding. The flexible display 200 in the fold-out mode may be exposed to the first surface.
As shown in fig. 2, an unfolded state in which the first and second body parts 110 and 120 are unfolded flat may be defined as a first state. As shown in fig. 1, a state in which the first and second body parts 110 and 120 overlap may be defined as a second state.
A length of the flexible display 200 exposed to the first surface in the first state may be defined as a first length, and a length of the flexible display 200 exposed to the first surface in the second state may be defined as a second length. The width of the flexible display 200 may be the same in the first state and the second state. In the fold-out mobile device, the flexible display 200 does not bend in the width direction.
In the folding-out moving device of the present invention, the first length is shorter than the second length. All exposed portions of the first face may be surrounded by the flexible display 200 in an unfolded state where the flexible display 200 becomes the longest with respect to the body portion, except at the instant the length of the flexible display 200 becomes the shortest with respect to the body portion, i.e. in a folded state.
Referring to fig. 1, the total length of the flexible display 200 is L1+ L2+ L1. Referring to fig. 2, the total length of the flexible display 200 is L4+ L1+ L3+ L1+ L4. In both fig. 1 and fig. 2, the total length of the flexible display 200 is unchanged, and thus L1+ L2+ L1 is equivalent to L4+ L1+ L3+ L1+ L4.
Referring to fig. 1, a second length as the flexible display 200 exposed to the outside of the case 400 in the folded state is L1+ L2+ L1. For convenience of explanation, it is assumed that the entire length of the flexible display 200 in fig. 1 is exposed to the outside of the housing 400, and thus the second length is equal to the total length of the flexible display 200.
Referring to fig. 2, a first length, which is a length of the flexible display 200 exposed to the outside of the case 400 in the unfolded state, is L1+ L3+ L1. The first length is L4+ L4 shorter than the total length L4+ L1+ L3+ L1+ L4 of the flexible display 200.
Thus, the first length is shorter than the second length. Since it is assumed that the entire length of the flexible display 200 is exposed in the folded state, the first length is shorter than the second length by L4+ L4. L4+ L4, which is the difference between the first length and the second length, can be regarded as the length accommodated in the interior of the case 400.
Accordingly, there may be no gap between the edge of the housing 400 and the flexible display 200. This is a feature of the present invention that the first surface is not completely covered by the flexible display 200 in the fold-out mode. The greater the thickness of the first body part 110 and the second body part 120, the more prominent the advantages of the present invention can be.
As an embodiment, the flexible display 200 may be longer than the total of the length of the hinge unit 130, the length of the first body part 110, the thickness of the first body part 110, the length of the second body part 120, and the thickness of the second body part 120. In the case of the flexible display 200, it may be sufficiently long in consideration of the thickness of the first and second body parts 110 and 120, and the remaining part may be accommodated inside the case 400. The end of the flexible display 200 received in the interior of the case 400 may be bent when being wound.
The end portion or the fixing portion 203 of the flexible display 200 may be accommodated inside the housing 400 covering the second face of the first body part 110 or the second face of the second body part 120.
Accordingly, at all rotation angles including the first state and the second state, the end portion of the flexible display 200 may not be exposed to the outside of the case 400, and the exposed first faces of the first and second body parts 110 and 120 may be always surrounded by the flexible display 200.
The case 400 may cover the second face of the first body part 110 or the second face of the second body part 120.
When changing from the second state to the first state, the flexible display 200 may be bent into the interior of the housing 400. The flexible display 200 can be out of the housing 400 by the difference between the first length and the second length.
Next, the sliding unit 300 that tightly supports the flexible display 200 without wrinkles or lifting will be explained.
The sliding unit 300 may face at least one of the first and second body parts 110 and 120. The sliding unit 300 may be disposed between the flexible display 200 and at least one of the first and second body parts 110 and 120. When the first body part 110 or the second body part 120 rotates, the sliding unit 300 may slide the flexible display 200 relative to the first body part 110 or the second body part 120.
The upper surface of the sliding unit 300 is attached to the flexible display 200, and the rear surface may face at least one of the first body part 110 and the second body part 120. When the first body part 110 or the second body part 120 rotates, the upper surface of the sliding unit 300 may move together with the flexible display 200, and there may be no relative movement between the flexible display 200 and the sliding unit 300. The rear surface of the sliding unit 300 may slide with respect to the first body part 110 or the second body part 120. Thereby, it may correspond to a difference in length of the body part and the flexible display 200.
The sliding unit 300 may be provided with at least one of a support plate and a chain block.
The support plate may be linearly movable with respect to the first body part 110 or the second body part 120.
A plurality of chain blocks may be provided at the end of the support plate. The chain blocks may support the bent portions of the flexible display 200. One link may be rotatable relative to the other at all angles including the first state and the second state.
