Background

Recently, for a large screen display, a foldable mobile device mounted with a flexible display is being developed. 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. 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.

On the other hand, the folding-out method is shown by samsung electronics, chinese huashi, and rouyu, and is a method in which the first body portion and the second body portion are folded and the flexible display is bent at a large curvature radius 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, in the fold-out manner, 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.

Detailed Description

The mobile device of the present invention will be described with reference to fig. 1 and 7.

The mobile device of the present invention may include a body part 500, a flexible display 300, and a moving

part

110, 120, 130. The main body 500 may be provided with a housing that forms the exterior and in which most of the components including a main board of the mobile device, a battery, and the like are disposed.

Referring to fig. 1, there is shown a closed state in which the flexible display 300 is exposed by an amount of less than or equal to the length or width of the body part 500. In the case of a mobile device, exposure of a screen in a closed state as shown in fig. 1 is minimized, and the overall size is minimized, enabling improved portability. For convenience of carrying, the flexible display 300 may be in a closed state where a part thereof is accommodated in the main body 500 at ordinary times. In fig. 1, the side cover 102 is removed so that the main portion can be visually seen. The side cover 102 may cover the rail unit 200 to prevent inflow of foreign substances, block access from the outside to the inside of the body part 500, and may exert a waterproof or antifouling function.

Referring to fig. 2, the open state is shown. When the first moving part 110 is pulled toward the lateral direction of the body part 500 by a user in the closed state, or the flexible display 300 is pushed toward the lateral direction of the body part 500, it may become the open state when the first moving part 110 is linearly moved.

Referring to fig. 2, the flexible display 300 may be unfolded from the body part 500, the flexible display 300 becomes an unfolded state that is unfolded longer than the length or width of the body part 500, and a large screen may be implemented. In the open state, an exposed area of the flexible display 300 may be maximized, and the flexible display 300 received inside the body part 500 may be minimized.

Since the flexible display 300 is easily bent, a mechanism for supporting the flexible display 300 in a flat state is required in order to form a screen. The first moving part 110 may support at least a portion of the flexible display 300. On the other hand, in order to implement an edge screen, the end of the first moving part 110 may be a curved surface. The first moving part 110 may partially support the flexible display 300 as a curved surface as an example of an edge portion, or support a wider area of the flexible display 300 as a planar state. The first moving part 110 may support the flexible display 300 not to be bent by an external force.

When the flexible display 300 is unfolded from the closed state of fig. 1 to the open state of fig. 2, a large screen can be implemented even if the size of the body part 500 is small. Compared with the previous inward folding or outward folding mode, the utility model discloses a slip mode or the mode of can rolling up can avoid the screen fold to appear from the root when realizing the large screen to the rotation center of this part 500 disappears, therefore can avoid the problem that the length of the flexible display 300 that exists is not enough in the folding mode.

The first moving part 110 can linearly move on the front surface 501 of the body part 500. The rail unit 200 may be provided to the body part 500 and guide the linear movement of the first moving part 110. The rail unit 200 may movably support both end portions of at least one of the first, second, and third moving

parts

110, 120, and 130. The rail unit 200 may be provided at a side surface of the body part 500 for the movement accuracy of the moving

parts

110, 120, 130. Thereby, a play of the flexible display 300 that is extended and retracted can be removed.

The total area of the flexible display 300 is preferably equal to or more than the area of the front surface 501 of the main body 500 where the flexible display 300 is exposed in the open state. In the closed state, the remaining portion of the flexible display 300 may be accommodated inside the body part 500 in a rollable state or a sliding state. When the flexible display 300 is rollably or slidably accommodated in the main body part 500, the folding of the flexible display 300 can be prevented from being broken, compared to the conventional folding method in which the flexible display 300 is folded.

On the other hand, since the first moving portion 110 is a flat plate having no flexibility, the flexible display 300 cannot be supported by being able to be bent and deformed. In order to support the bent portion of the flexible display 300, a second moving part 120 that moves curvilinearly may be provided.

The second moving part 120 may be moved curvilinearly from the front surface 501 toward the rear surface 502 of the body part 500 or moved curvilinearly from the rear surface 502 toward the front surface 501 of the body part 500. An end of the second moving part 120 may face an end of the first moving part 110. When a gap occurs between the first moving part 110 and the second moving part 120, the support state of the flexible display 300 may be cut off or tilted. In order to prevent this, it is preferable that the first moving part 110 and the second moving part 120 are closely contacted without a step.

Since the structure becomes complicated if a separate member is provided to guide the curved movement of the second moving portion 120, it is preferable to use the rail unit 200 as a common guide mechanism. The rail unit 200 may guide not only the linear movement of the first moving part 110 but also the curved movement of the second moving part 120. A portion of the flexible display 300 supported by the first moving part 110 may linearly move in a planar state with respect to the body part 500 without bending deformation. Since the remaining portion of the flexible display 300 supported by the second moving part 120 is bent and deformed, it may be wound around the side surface of the main body part 500 in a curved state. This portion may be supported by the second moving portion 120 so as to be able to be bent.

On the other hand, a mechanism for supporting the opposite side planes of the flexible display 300 without bending deformation is required. When the margin portion of the flexible display 300 is large or the expansion and contraction amount of the first moving part 110 is large, a supporting mechanism of the opposite side plane may be further required. For this, the third moving part 130 supporting the flexible display 300 on the rear surface 502 of the body part 500 may be provided.

The third moving part 130 may linearly move at the rear surface 502 of the body part 500. The second moving part 120 may be connected to the first moving part 110 and the third moving part 130 to perform a curved movement.

The rail unit 200, which is a common guide mechanism for slimness and simplification of the structure of the body part 500, may guide linear movement of the first and third moving

parts

110 and 130 on the one hand, and curved movement of the second moving part 120 on the other hand. A portion of the flexible display 300 supported by the first and third moving

parts

110 and 130 is in a state of no bending deformation and can move linearly with respect to the body part 500. The remaining portion of the flexible display 300 supported by the second moving part 120 is bent and deformed, and may be wound around the side surface of the main body part 500 in a curved state.

The moving

parts

110, 120, and 130 of the present invention may be moved by a motor or a driver, but may be semi-automatically operated for low power, slimness, and shielding of failure factors. By purely manual means, the flexible display 300 may easily shake because there is no mechanism to maintain the closed state or the open state.

The hinge spring 106 may be connected to the body part 500 and the first moving part 110 for a semi-automatic operation. The hinge spring 106 may apply an elastic force to the moving

parts

110, 120, 130 with respect to the body part 500. The position where the hinge spring 106 is disposed is not limited to the first moving part 110, and may be disposed in the second moving part 120 or the third moving part 130. When the hinge spring 106 is provided at the second moving part 120 or the third moving part 130, the second moving part 120 or the third moving part 130 may be elastically pushed and an indirect elastic force may be applied to the first moving part 110.

As shown in fig. 1 and 3, a state in which the first moving part 110 and the body part 500 are folded may be defined as a closed state. As shown in fig. 2 and 4, a state in which the first moving part 110 is unfolded from the body part 500 may be defined as an opened state. When the position where the hinge spring 106 is maximally compressed is defined as the turning point, the turning point may exist between the closed state and the open state. The reference numeral L0 denotes a turning point spring pitch which is a pitch for unfolding the hinge spring 106 at the turning point.

In fig. 3 and 4, as the hinge spring 106, a torsion spring is shown. Without being limited thereto, the hinge spring 106 may be a compression coil spring, an extension coil spring, or a plate spring.

The hinge spring 106 may exert an elastic force in a direction from the turning point toward the closed state or in a direction toward the open state. The hinge spring 106 may elastically push the moving

parts

110, 120, 130 to be in the closed state. Reference numeral L1 denotes a closing spring pitch as a pitch for unfolding the hinge spring 106 in the closed state. Because the knee spring spacing L0 is minimal, the closing spring spacing L1 may be greater than the knee spring spacing L0.

The hinge spring 106 may elastically push the first moving part 110 in a direction from the turning point toward the opened state. The opening spring interval L2, which is an interval to unfold the hinge spring 106 in the open state, may be greater than the inflection point spring interval L0.

The second moving part 120 may support the flexible display 300 in a curved state so that the flexible display 300 has a shape surrounding the side surface of the main body part 500. The second moving part 120 may include a plurality of chain blocks 122. A plurality of chain blocks 122 may be guided along the rail unit 200. Since the moving track is a curve, one link 122 can rotate relative to the other link 122.

The first moving part 110 may linearly move on the front surface 501 of the body part 500, and the third moving part 130 may linearly move on the rear surface 502 of the body part 500. The second moving part 120 may connect the first moving part 110 and the third moving part 130 and move curvilinearly at a side surface of the body part 500.

The rail unit 200 may include a first rail 210 guiding the linear track of the first moving part 110, a second rail 220 guiding the curved track of the second moving part 120, and a third rail 230 guiding the linear track of the third moving part 130. The first rail 210 may be adjacent to the front surface 501 of the body portion 500, the second rail 220 may be adjacent to a side surface of the body portion 500, and the third rail 230 may be adjacent to the rear surface 502 of the body portion 500. The first moving part 110 may be inserted in the first guide rail 210 to be linearly movable, the second moving part 120 may be inserted in the second guide rail 220 to be curvilinearly movable, and the third moving part 130 may be inserted in the third guide rail 230 to be linearly movable.

Since the first and third moving

parts

110 and 130 have a flat plate shape, if the first and

third guide rails

210 and 230 are shared, a disadvantage that the moving distance becomes short is expected. Since the second moving part 120 connects the first moving part 110 and the third moving part 130, the second rail 220 is an extended portion of the first rail 210 or an extended portion of the third rail 230, which is advantageous for slimness and simplification of the structure.

According to fig. 7, in order to secure a long moving distance of the first moving part 110, the second guide rail 220 and the third guide rail 230 may be connected to each other. The second guide rail 220 and the third guide rail 230 may be provided separately from the first guide rail 210. In order to maximize the moving distance of the first moving part 110, the first guide rail 210 may be formed to be long across the second side surface part 520 from the first side surface part 510 of the body part 500. Thus, connecting the second guide rail 220 with the third guide rail 230 can reduce the number of formed guide rails to a minimum.

Next, means for improving the assembling property will be described.

When the first moving part 110 is assembled to the main body part 500, the first moving part 110 may be inserted into the rail unit 200 in a first direction from the first side surface part 510 corresponding to one side of the side surface of the main body part 500 toward the second side surface part 520 corresponding to the other side of the side surface of the main body part 500.

Referring to fig. 6 and 7, the first rail opening 211, which is a starting point where the first moving part 110 is inserted, may be located at the first side surface part 510 of the body part 500. The first rail 210 may extend in the first direction from the first rail opening 211 located at the first side surface portion 510.

The second side surface portion 520, which is the other side of the side surface of the body portion 500, may be blocked by the second guide rail 220, which is a curved rail. When the third moving part 130 is assembled to the main body part 500, the third moving part 130 may be inserted into the rail unit 200 from the first side surface part 510 in the first direction.

Referring to fig. 6 and 7, the third rail opening 231, which is a starting point where the third moving part 130 is inserted, may be located at the first side surface part 510 corresponding to one side of the side surface of the body part 500. The third rail 230 may extend in the first direction from the third rail opening 231 located at the first side surface portion 510.

To minimize the number of rails, the second rail 220 may be connected with a third rail 230. At this time, the second moving part 120 may be assembled in the first direction with the third rail opening 231 as a starting point. The second moving part 120 inserted into the third rail opening 231 may pass through the third rail 230, which is a linear section, to reach the second rail 220, which is a curved section.

The first moving part 110 and the third moving part 130 may move in opposite directions. The first rail opening 211 through which the first moving part 110 is inserted into the main body part 500 may be provided in the rail unit 200, and the third rail opening 231 through which the third moving part 130 is inserted into the main body part 500 may be provided in the rail unit 200. The first and

third rail openings

211 and 231 may be gathered at one side of the rail unit 200 to be opened or exposed.

The flexible display 300 may comprise a first face 301 on one side and a third face 303 on the other side. The first surface 301 may be closely fixed to the first moving part 110, and the third surface 303 may be closely fixed to the third moving part 130.

The second face 302 between the first face 301 and the third face 303 may surround the side face or the second side face portion 520 of the body portion 500. Since the second surface 302 is bent and deformed, residual stress may be generated when the second surface is fixedly bonded to the second movable portion 120. When the second moving portion 120 is formed by a plurality of chain pieces 122, the adhesion of the second face 302 to the surface of each chain piece 122 may generate a pattern in which the second face 30 is sharply folded at the connecting portion of the chain pieces 122. In order to reduce local abrupt curvature change of the second surface 302 and continuously form a soft curved surface, the second surface 302 may be supported on the surface of the second moving part 120 in a non-adhered or non-fixed state.

On the other hand, after each of the moving

parts

110, 120, and 130 is assembled to the rail unit 200, the flexible display 300 may be fixed to the first moving part 110 or the third moving part 130. As described above, each link block 122 and the flexible display 300 may be in an unfixed state. The flexible display 300 may be a force transmission mechanism for each of the moving

parts

110, 120, 130. When the first moving part 110 is pulled, various parts can be easily pulled through the transmission of the pulling force of the flexible display 300.
