In addition, a slide-out phone which is convenient and has high durability can be manufactured.

Description

Mobile device equipped with a flexible display

[0001] The present invention relates to a mobile device equipped with a flexible display.

[0002] It has been a long time since mobile devices equipped with flexible displays were commercialized. However, the thick thickness and heavy weight required to house the flexible display are slowing down the pace of commercialization. Additionally, visual lines and physical non-uniformity present on the screen are causing visual instability and durability issues when consuming visual content. Although the Korean Publication KR10-2023-0037610 (Folding type mobile terminal) introduces an internal hinge structure in the form of a leaf spring attached to the panel, which significantly contributes to reducing screen creases, the creases have not completely disappeared due to the wide gap between the left and right fold parts caused by the incompleteness of the main hinge structure of foldable flexible display mobile devices.

[0003] This invention aims to slim down foldable flexible display mobile devices and enable flexible sliding during folding and unfolding by utilizing long, streamlined hexagonal left and right folders. Upon unfolding, an oval panel section, such as a teardrop shape, is stored inside the foldable phone, and the lower part of the display section is firmly supported. This ensures visual stability and physical uniformity by eliminating screen creases in the display panel, while also enhancing durability through visual versatility via angle adjustment and the simplification of the mechanism's operation. Furthermore, the same mechanism is applied to slide-out phones to improve the convenience and durability of slide expansion. Additionally, the invention seeks to achieve automation of the insertion and withdrawal of highly durable slide-out phones using a motor.

[0004] To solve this problem, the present invention provides a first folder part (100) and a second folder part (101) of a foldable phone, and a folder slider (104) that slides in each folder part, with a slightly elongated streamlined hexagonal shape when viewed from the side, thereby providing a storage space for a panel inside the first folder part and the second folder part when the foldable phone is folded, and minimizing the gap between the left and right folder parts when unfolded, thereby storing and supporting a display panel (400) with a plate spring attached, etc., and thus effectively removing screen wrinkles.

[0005] Figure 1 shows the overall appearance of a foldable flexible display mobile device, exemplifying when these configurations are combined.

[0006] To achieve this effect, the hinge body part (300) in FIG. 2 has a gear hinge shaft (200) so that the left and right hinges can rotate, and the gear hinge shaft (200) is also provided with a hinge shaft slider (301) so that the shaft can slide and move. At this time, the hinge shaft slider (301) may have a gear groove, such as a rack gear, that meshes with the gear so that the gear hinge shaft (200) can rotate.

[0007] In FIG. 3, the first folder section (100) and the second folder section (101) face each other, and the long hexagonal shape at the ends of the two creates a space to store the display panel (400) in a gentle curved shape. In FIG. 3, the long streamlined hexagonal end that does not touch the first folder section (100) and the second folder section (101) comes into contact with the lower part of the hinge body section (300) to be folded and unfolded, thereby taking on a somewhat curved shape or forming a guide groove in the hinge body section (300) to have a line that minimizes gaps between them.

[0008] At this time, the first folder part (100) and the second folder part (101) are fixed to the hinge axis, and the end thereof is connected to the panel support plate hinge axis coupling part (402) of the panel support plate (401). When the first folder part (100) and the second folder part (101) rotate, the panel support plate (401) can be lifted according to the angle and smoothly positioned by having a folder part panel support plate support part (107). Typically, a metal layer in the form of a plate spring is inserted at the bottom of the panel to lift the panel support plate according to the angle on its own, but if a folder part panel support plate support part (107) is present at each angle, it can be fixed more firmly. It is preferable to make the end of the folder part panel support plate support part (107) in a U-shape that extends to the left and right hinge axis or the up and down hinge axis, but it can have various shapes. In addition, the folder panel support plate (401) may also have grooves in the middle of the support plate to allow the left and right connecting circuits to pass through.

[0009] FIG. 4(a) shows a gear hinge shaft (200) and a slider gear (201) having a slightly larger diameter that is coupled thereto. Even if the gear hinge shaft (200) and the slider gear (201) move at the same angle, the slider gear (201) with a larger diameter has a longer circumference as it has more gums, thereby causing the gear-coupled folder slider (104) to slide further away from the folder. As shown in FIG. 4, the gear hinge shaft (200) and the slider gear (201) can be made in a form that combines two gears of different sizes to form an integrated structure.

[0010] In FIG. 4(b), two gear hinge shafts (200) and multiple slider gears (201) are linked to an integrated gear shaft (202) to form a single structure. While angle-adjustable hinge structures are available on the market, additionally, multiple slider gears (201) are present to form an integrated structure and increase friction, making angle adjustment easier.

[0011] Additionally, when the folder slider (104) is connected to the folder slider integrated bar (105) and integrated, some of the slider gears (201) may use elastic rubber or the like instead of a gear structure, or adopt a method of increasing friction by laying elastic rails on the top and bottom inside the folder slider. This has a more advantageous effect for angle adjustment of the foldable phone.

[0012] FIG. 5 shows that the gear hinge shaft (200) and the slider gear (201) are linked to the integrated gear shaft (202), and an upper gear groove folder slider (102) of the rack gear type, which is positioned at the top of the slider and slides in a direction that matches the rotational direction of the gear hinge shaft, or a lower gear groove folder slider (103) of the rack gear type, which slides in a direction opposite to the rotational direction of the gear hinge shaft, can be provided to slide in various directions.

[0013] FIG. 6 shows a side view of the folder slider (104). Making the folder slider (104) slide at both the top and bottom of the folder contributes to structural stability. Additionally, the folder slider integrated bar (105), which makes the folder slider (104) an integral unit, is attached to the bottom of the folder slider (104) to facilitate the smooth crossing of the left and right folder sliders (104). It can also be attached in various other forms.

[0014] FIG. 7 illustrates a configuration in which, when the folder slider (104) drawn out from the first folder section (100) and the second folder section (101) is drawn out without sufficient interlocking, the folder slider (104) pushes up the display panel support plate (401) according to the rotation of the gear hinge shaft (200). The display panel support plate is in the shape of a trapezoid with a long top and a short bottom, and is pushed up by the diagonal structure of the folder slider (104), and the folder panel support plate support section (107) pushes up the panel support plate (402). At this time, the metal layer having elasticity within the panel lifts the panel itself, and the folder panel support plate support section adjusts this. They are in close contact with each other so that the gap is minimized when the foldable device is unfolded.

[0015] Depending on the manufacturing method, in addition to the folder slider (104), it may be pushed up by the diagonal structure of the first folder section (100) and the second folder section (101).

[0016] This structure can be used in all folding terminals that are folded one or more times, and in a folding terminal where the flexible display is exposed to the outside when folded, two gear hinge shafts (200) and a plurality of slider gears (201) are linked to an integrated gear shaft (202) to form a single structure, which is fixed to the hinge body part (300), and the folder slider (104) can be made in a form where the folder slider is pulled out from the hinge body part (300) and pushes the left and right folder parts.

[0017] The left and right folder sections or folder section sliders may have grooves for connecting the left and right folder sections.

[0018] FIG. 7 is an example of the operation of a panel support plate (401) located between the left and right folder sliders (104) when they cannot completely cross each other. A part of this panel support plate (401) is attached to the bottom of a plate spring, etc., which is an internal hinge of the panel (400). At this time, it is preferable to place the hinge axes of the plate spring, etc. at two locations on the left and right that are slightly away from the attachment part of the panel support plate (401).

[0019] FIG. 8 is an example of applying the mechanism of the present invention to a slider-out phone (500).

[0020] This mechanism can be applied to both unilateral and unilateral expansion of the slider-out phone (500), and unilateral or unilateral expansion is also possible in a hybrid form where the slider-out phone is combined with a foldable phone base. The screen of the slider-out phone (500) faces downward, and FIG. 8 shows the bottom of the slider phone. The slide expansion rotation bar (502) may be installed so that it can rotate upward from the screen side of the slide-out phone. The overall exterior of the slide rotation bar (502) may be rectangular, while the interior may adopt a completely closed, open, or partially open type. When the slide expansion rotation bar (502) is rotated, the hinge gear shaft (200) fixedly connected to the slide expansion rotation bar rotates, and the slider gear (201) linked thereto rotates together, pushing the expansion slider through the rack gear, etc., thereby expanding the slide expansion part (501). The slide extension rotating bar (502) rotates at a 180-degree angle to support the slide extension part (501) from the side and bottom surfaces, thereby strengthening the support and durability.

[0021] In actual use, the slide extension rotating bar (502) can be rotated about 90 degrees to partially extend the slide extension part (501) and used as a stand when placed on a desk.

[0022] The slide extension rotating bar adjustment device (503) fixes the rotating bar and the slide extension part (501) by using a multi-stage pipe commonly used in carriers or by using a spring device inside the pipe. Since the slide extension rotating bar adjustment device (503) is a known technology available for use, a description is omitted.

[0023] In FIG. 9, a plurality of slider gears (201) linked to a hinge gear shaft (200) are installed sequentially, and according to the principle of a lever, the plurality of slider gears (201) rotate sequentially in accordance with the rotation of the hinge gear shaft (200). Depending on the number of slider gears (201), the number of teeth of the slider gears (201), and the cross direction of the slider gears (201), not only forward and backward movement but also movement of various lengths can be produced. The hinge gear shaft (200) and the plurality of slider gears (201) can be combined in various ways using various types of gears, such as a horizontal axis, a cross axis where the direction of the hinge gear shaft and the slider gear (201) axis changes using bevel gears, or an oblique axis. In addition, the position of the rack gear that causes the slider to slide can be arranged in various ways on the upper, lower, left, and right sides inside the slider. Although the folder slider (104) is illustrated in FIG. 9, it can be applied in the same way to the slide extension part (501) of the slide-out phone (500).

[0024] FIG. 10 illustrates the configuration of multiple gears and rack gears within a slide bar. Since it is difficult to use large-diameter gears when manufacturing a thin profile, multiple small gears are arranged in succession. Depending on the degree of sliding, different gears act as pinions, and rack gears are sequentially arranged and linked within a single slider or multiple sliders to enable movement like a multi-stage pipe. When multiple gears are used as a group, the diameter of the pinion gear linked to the rack gear is larger than that of the other gears to ensure smooth linkage between the pinion gear and the rack gear.

[0025] FIG. 11 shows the shape of a slide-extending rotating bar (502) attached to a slide-out phone (500). In order to provide a gripping space when the slide-extending rotating bar (502) rotates, a portion of it is recessed, differing from the outer line of the slide-out phone.

[0026] The present invention is equally applicable to all devices that use a flexible display to expand the screen by folding and sliding, such as mobile devices, display devices, desktop PCs, laptop PCs, tablet PCs, e-books, and navigation systems.

[0027] In FIG. 12, one or more folding support auxiliary members (601) can be installed symmetrically on the left and right sides of the hinge body. At this time, the inner side of the folding support auxiliary member is provided with a groove to allow the components of the left and right folders to move without colliding. A pair of folding support auxiliary member elastic device attachment bars (602) are provided on the folding support auxiliary member. An elastic device composed of a spring, a flexible material, and a rigid cover is placed on a fixed column, so that when the left and right folders rotate, the elastic device is compressed and allows movement through the folding support auxiliary member elastic device attachment bar sliding groove (603). When folding stops, the folding support auxiliary member elastic device acts as a stopper. The folding support auxiliary member elastic device attachment bar sliding groove (603) is installed in a space created by placing a partition in a part of the interior of the left and right folders.

[0028] FIG. 13 shows that a folder bottom streamlined rack gear (701) is placed at the bottom of the left and right folder sections so that the left and right folders rotate uniformly. As the folder bottom streamlined rack gear (701) rotates, it rotates the folder bottom worm gear (702), and the folder bottom worm gear (702) rotates the folder bottom horizontal gear (703) so that the left and right folders fold and unfold uniformly. The folder bottom horizontal gear (703) can be made of a spur gear or a helical gear, etc.

[0029] Figure 14 shows the form of a flexible display slide-out phone.

[0030] FIG. 15 shows the slide-out slider (801) and the slide-out auxiliary slider (802) combined in a stepped manner.

[0031] FIG. 16 shows an example of a circular slide-out conveyor (803) for overcoming a step difference during slide-out. A circular conveyor belt is preferred, but a straight conveyor belt is also acceptable.

[0032] When using the invention technology of a foldable flexible display mobile device having a slim hinge slider structure, the following effects are achieved.

[0033] First, it is possible to manufacture foldable flexible display mobile devices in a thin form factor.

[0034] Second, it has the effect of eliminating screen creases when unfolding foldable flexible display mobile devices.

[0035] Third, foldable flexible display mobile devices have high durability due to their folding and unfolding mechanism.

[0036] Fourth, it becomes easier to adjust the screen angle of foldable flexible display mobile devices.

[0037] Fifth, the hinge mechanism can be applied to slide-out phones, increasing the durability of the slide-out and the convenience of manual expansion.

[0038] Sixth, enhance usability by making the automatic entry and exit of the slide-out phone convenient.

[0041] FIG. 3 is an example diagram of the configuration of a flexible display mobile device having a slim hinge slider structure.

[0042] FIG. 4 is an example of the interaction between a gear hinge shaft (200) and a slider gear (201).

[0043] FIG. 5 is an example of an upper gear groove folder slider (102) that is positioned at the top of a slider and slides in a direction that matches the rotational direction of the gear hinge shaft, and a lower gear groove folder slider (103) that slides in a direction opposite to the rotational direction of the gear hinge shaft, wherein the gear hinge shaft (200) and the slider gear (201) are linked to the integrated gear shaft (202).

[0044] FIG. 6(a) is a side view of the folder slider (104).

[0045] FIG. 6(b) is an example diagram showing a folder slider integrated bar (105) that enables multiple folder sliders (104) to move as a single body. The folder slider integrated bar (105) is attached to the lower part of the folder slider (104) to prevent left and right collisions during sliding.

[0046] The folder slider integrated bar (105) can have various shapes, such as straight lines, curves, or uneven shapes.

[0047] FIG. 7 is an example of the operation of a panel support plate (401) located between the left and right folder sliders (104) when they cannot completely cross each other. A part of this panel support plate (401) is attached to the bottom of a plate spring, which is an internal hinge of the panel (400).

[0048] FIG. 8 is an example of applying the mechanism of the present invention to a slider-out phone (500).

[0049] FIG. 9 illustrates a plurality of slide gears (201) that enable wide sliding.

[0050] FIG. 10 illustrates the configuration of multiple gears and rack gears within a slide bar. Since it is difficult to use large-diameter gears when manufacturing a thin profile, multiple small gears are arranged in succession. Depending on the degree of sliding, different gears act as pinions, and the gears can be made to move along one or more interconnected rack gears arranged sequentially.

[0051] FIG. 11 shows the shape of a slide-extending rotating bar (502) attached to a slide-out phone (500). In order to provide a gripping space when the slide-extending rotating bar (502) rotates, a portion of it is recessed, differing from the outer line of the slide-out phone.

[0052] FIG. 12 is an example of the installation of one or more folding support auxiliary parts (601) on the left and right sides of the hinge body.

[0053] FIG. 13 is an example diagram showing how the left and right folders can rotate uniformly. A folder bottom streamlined rack gear (701) is placed at the bottom of the left and right folder sections. As the folder bottom streamlined rack gear (701) rotates, it rotates the folder bottom worm gear (702), and the folder bottom worm gear (702) rotates the folder bottom horizontal gear (703), causing the left and right folders to fold and unfold uniformly. The folder bottom horizontal gear (703) can be made of a spur gear or a helical gear.

[0054] Figure 14 shows the form of a flexible display slide-out phone.

[0055] The slide-out slider (801) and the slide-out auxiliary slider (802) form a single unit, and when the two are pulled out, the slide-out conveyor belt (803) is rolled in the slide-out forward rolling (804) and the slide-out rear rolling (805) and moves forward.

[0056] At this time, a part of the conveyor belt (803) is made thick and a part thin, and a slide-out slider (801) is attached to the thin part. With this structure, no step difference occurs when the slide-out slider (801) is pulled out. In addition, it provides support to enable wide sliding. In the slide-out forward rolling of FIG. 14, the roller and the gear are connected in a straight line, and the two can be installed with the roller and gear intersecting.

[0057] Figure 5 shows an example of multiple gears connected in a straight line, with a rolling structure placed between these slider gears (201). The gears are located on the inner side of the slide-out auxiliary slider (802), and a rack gear of the sliding length is placed on this inner side to allow sliding. Additionally, a motor connected to the gears is connected to a power button to operate it, causing it to slide and extend or retract.

[0058] FIG. 15 shows the slide-out slider (801) and the slide-out auxiliary slider (802) combined in a stepped manner.

[0059] FIG. 16 shows an example of a circular slide-out conveyor (803) for overcoming a step difference during slide-out. A circular conveyor belt is preferred, but a straight conveyor belt is also acceptable.

[0060] To solve this problem, the present invention includes a first folder part (100) and a second folder part (101) of a foldable phone, and a folder slider (104) that slides in each folder part, and a slightly elongated polygonal shape in which a space can be created on the inside when viewed from the side, and in the example, a hexagonal shape, thereby providing a storage space for the panel when the foldable phone is folded and minimizing the gap between the left and right folder parts when unfolded, so as to store and support a display panel (400) with a plate spring attached, thereby having the effect of removing screen wrinkles.

[0061] Figure 1 shows the overall appearance of a foldable flexible display mobile device, exemplifying when these configurations are combined.

[0062] In order to achieve this effect, the hinge body part (300) in FIG. 2 has a gear hinge shaft (200) so that the left and right hinges can rotate, and the gear hinge shaft (200) is also provided with a hinge shaft slider (301) so that the shaft can slide and move. At this time, the hinge shaft slider (301) may have a gear groove, such as a rack gear, that meshes with the gear so that the gear hinge shaft (200) can rotate.

[0063] In FIG. 3, the first folder section (100) and the second folder section (101) face each other, and the long hexagonal shape at the ends of the two creates a space to store the display panel (400) in a gentle curved shape. In FIG. 3, the long hexagonal end that does not touch the first folder section (100) and the second folder section (101) comes into contact with the lower part of the hinge body section (300) to be folded and unfolded, thereby taking on a somewhat curved shape or forming a guide groove in the hinge body section (300) to have a line with minimized gaps between them.

[0064] At this time, the first folder part (100) and the second folder part (101) are fixed to the hinge axis, and the end thereof is connected to the panel support plate hinge axis coupling part (402) of the panel support plate (401) so as to be rotatable and sliding, so that when the first folder part (100) and the second folder part (101) rotate, the panel support plate (401) can be lifted according to the angle and smoothly positioned, and the folder part panel support plate support part (107) can be provided. Typically, a metal layer in the form of a plate spring is placed at the bottom of the panel to lift the panel support plate according to the angle on its own, but if the folder part panel support plate support part (107) is present at each angle, it can be fixed more firmly. It is preferable to make the end of the folder part panel support plate support part (107) in a U-shape that extends to the left and right hinge axis or the up and down hinge axis, but it can have various shapes. In addition, the panel support plate hinge shaft coupling part (402) may be omitted and the panel support plate (401) may be made to move at the bottom, or grooves may be placed in the middle of the support plate to allow the left and right connecting circuits to pass through the panel support plate (401).

[0065] FIG. 4(a) shows a gear hinge shaft (200) and a slider gear (201) having a slightly larger diameter that is coupled thereto. Even if the gear hinge shaft (200) and the slider gear (201) move at the same angle, the slider gear (201) with a larger diameter has a longer circumference as it has more gums, thereby causing the gear-coupled folder slider (104) to slide further away from the folder. As shown in FIG. 4, the gear hinge shaft (200) and the slider gear (201) can be made in a form that combines two gears of different sizes to form an integrated structure.

[0066] In FIG. 4(b), two gear hinge shafts (200) and multiple slider gears (201) are linked to an integrated gear shaft (202) to form a single structure. While angle-adjustable hinge structures are available on the market, additionally, multiple slider gears (201) are present to form an integrated structure and increase friction, making angle adjustment easier.

[0067] Additionally, when the folder slider (104) is connected to the folder slider integrated bar (105) and integrated, some of the slider gears (201) may use elastic rubber or the like instead of a gear structure, or adopt a method of increasing friction by laying elastic rails on the top and bottom inside the folder slider. This has a more advantageous effect for angle adjustment of the foldable phone.

[0068] FIG. 5 shows that the gear hinge shaft (200) and the slider gear (201) are linked to the integrated gear shaft (202), and an upper gear groove folder slider (102) of the rack gear type, which is positioned at the top of the slider and slides in a direction that matches the rotational direction of the gear hinge shaft, may be provided, or a lower gear groove folder slider (103) of the rack gear type, which slides in a direction opposite to the rotational direction of the gear hinge shaft, may be provided to allow sliding in various directions.

[0069] FIG. 6 shows a side view of the folder slider (104). Making the folder slider (104) slide at both the top and bottom of the folder contributes to structural stability. Additionally, the folder slider integrated bar (105), which makes the folder slider (104) an integral unit, is attached to the bottom of the folder slider (104) to facilitate the smooth crossing of the left and right folder sliders (104). It can also be attached in various other forms.

[0070] FIG. 7 illustrates a configuration in which, when the folder slider (104) drawn out from the first folder section (100) and the second folder section (101) is drawn out without sufficient interlocking, the folder slider (104) pushes up the display panel support plate (401) according to the rotation of the gear hinge shaft (200). The display panel support plate is in the shape of a trapezoid with a long top and a short bottom, and is pushed up by the diagonal structure of the folder slider (104), and the folder panel support plate support section (107) pushes up the panel support plate (402). At this time, the metal layer having elasticity within the panel lifts the panel itself, and the folder panel support plate support section adjusts this. They are in close contact with each other so that the gap is minimized when the foldable device is unfolded.

[0071] Depending on the manufacturing method, in addition to the folder slider (104), it may be pushed up by the diagonal structure of the first folder section (100) and the second folder section (101).

[0072] This structure can be used in all folding terminals that are folded one or more times, and in a folding terminal where the flexible display is exposed to the outside when folded, two gear hinge shafts (200) and a plurality of slider gears (201) are linked to an integrated gear shaft (202) to form a single structure, which is fixed to the hinge body part (300), and the folder slider (104) can be made in a form where the folder slider is pulled out from the hinge body part (300) and pushes the left and right folder parts.

[0073] The left and right folder sections or folder section sliders may have grooves for connecting the left and right folder sections.

[0074] FIG. 7 is an example of the operation of a panel support plate (401) located between the left and right folder sliders (104) when they cannot completely cross each other. A part of this panel support plate (401) is attached to the bottom of a plate spring, which is an internal hinge of the panel (400). This panel support plate (401) may be attached to a surface covered by a plate spring or a composite plastic plate, which is an internal hinge of the panel part, after covering it with rubber or plastic material. This panel support plate (401) can be made of various materials such as metal or plastic. In addition, if metal is used in the internal hinge part, electrical resistance may occur, but an insulating function can be provided by using a non-conductive coating material, which can reduce costs. If a panel support plate (401) is attached to the outer surface of such a coating material, the hinge rotation movement of the internal hinge can be made smoother. At this time, it is preferable to place the hinge axes of the plate spring, etc., at two locations on the left and right that are slightly away from the attachment part of the panel support plate (401).

[0075] FIG. 8 is an example of applying the mechanism of the present invention to a slider-out phone (500).

[0076] This mechanism can be applied to both unilateral and unilateral expansion of the slider-out phone (500), and unilateral or unilateral expansion is also possible in a hybrid form where the slider-out phone is combined with a foldable phone base. The screen of the slider-out phone (500) faces downward, and FIG. 8 shows the bottom of the slider phone. The slide expansion rotation bar (502) may be installed so that it can rotate upward from the screen side of the slide-out phone. The overall exterior of the slide rotation bar (502) may be rectangular, while the interior may adopt a completely closed, open, or partially open type. When the slide expansion rotation bar (502) is rotated, the hinge gear shaft (200) fixedly connected to the slide expansion rotation bar rotates, and the slider gear (201) linked thereto rotates together, pushing the expansion slider through the rack gear, etc., thereby expanding the slide expansion part (501). The slide extension rotating bar (502) rotates at a 180-degree angle to support the slide extension part (501) from the side and bottom surfaces, thereby strengthening the support and durability.

[0077] In actual use, the slide extension rotating bar (502) can be rotated about 90 degrees to partially extend the slide extension part (501) and used as a stand when placed on a desk.

[0078] The slide extension rotating bar adjustment device (503) fixes the rotating bar and the slide extension part (501) by using a multi-stage pipe commonly used in carriers or by using a spring device inside the pipe. Since the slide extension rotating bar adjustment device (503) is a known technology available for use, a description is omitted.

[0079] In FIG. 9, a plurality of slider gears (201) linked to a hinge gear shaft (200) are installed sequentially, and according to the principle of a lever, the plurality of slider gears (201) rotate sequentially in accordance with the rotation of the hinge gear shaft (200). Depending on the number of slider gears (201), the number of teeth of the slider gears (201), and the cross direction of the slider gears (201), not only forward and backward movement but also movement of various lengths can be produced. The hinge gear shaft (200) and the plurality of slider gears (201) can be combined in various ways using various types of gears, such as a horizontal axis, a cross axis where the direction of the hinge gear shaft and the slider gear (201) axis changes using bevel gears, or an oblique axis. In addition, the position of the rack gear that causes the slider to slide can be arranged in various ways on the upper, lower, left, and right sides inside the slider. Although the folder slider (104) is illustrated in FIG. 9, it can be applied in the same way to the slide extension part (501) of the slide-out phone (500).

[0080] FIG. 10 illustrates the configuration of multiple gears and rack gears within a slide bar. Since it is difficult to use large-diameter gears when manufacturing a thin profile, multiple small gears are arranged in succession. Depending on the degree of sliding, different gears act as pinions, and rack gears are sequentially arranged and interconnected within a single slider or multiple sliders to enable movement like a multi-stage pipe. When multiple gears are used as a group, the diameter of the pinion gear connected to the rack gear is larger than that of the other gears to ensure smooth interaction between the pinion gear and the rack gear.

[0081] FIG. 11 shows the shape of a slide-extending rotating bar (502) attached to a slide-out phone (500). In order to provide a gripping space when the slide-extending rotating bar (502) rotates, a portion of it is recessed, differing from the outer line of the slide-out phone. Various shapes that allow for a gripping groove when the slide-extending rotating bar (502) rotates can be applied.

[0082] The present invention is equally applicable to all devices that use a flexible display to expand the screen by folding and sliding, such as mobile devices, display devices, desktop PCs, laptop PCs, tablet PCs, e-books, and navigation systems.

[0083] In FIG. 12, one or more folding support auxiliary members (601) can be installed symmetrically on the left and right sides of the hinge body. At this time, the inner side of the folding support auxiliary member is provided with a groove to allow the components of the left and right folders to move without colliding. A pair of folding support auxiliary member elastic device attachment bars (602) are provided on the folding support auxiliary member. An elastic device composed of a spring, a flexible material, and a rigid cover is placed on a fixed column, so that when the left and right folders rotate, the elastic device is compressed and allows movement through the folding support auxiliary member elastic device attachment bar sliding groove (603). When folding stops, the folding support auxiliary member elastic device acts as a stopper. The folding support auxiliary member elastic device attachment bar sliding groove (603) is installed in a space created by placing a partition in a part of the interior of the left and right folders. In addition, to allow the left and right folders to rotate, they may be partially opened, inserted, or withdrawn so as not to get caught on the folding support support part (601).

[0084] FIG. 13 shows that a folder bottom streamlined rack gear (701) is placed at the bottom of the left and right folder sections so that the left and right folders rotate uniformly. As the folder bottom streamlined rack gear (701) rotates, it rotates the folder bottom worm gear (702), and the folder bottom worm gear (702) rotates the folder bottom horizontal gear (703) so that the left and right folders fold and unfold uniformly. The folder bottom horizontal gear (703) can be made of a spur gear or a helical gear, etc. The folder bottom streamlined rack gear (701) or the folder bottom worm gear (702) can also be replaced with a spur gear or a helical gear, etc., depending on the case.

[0085] Figure 14 shows the form of a flexible display slide-out phone.

[0086] The slide-out slider (801) and the slide-out auxiliary slider (802) form a single unit, and when the two are pulled out, the slide-out conveyor belt (803) is rolled in the slide-out forward rolling (804) and the slide-out rear rolling (805) and moves forward.

[0087] At this time, a part of the conveyor belt (803) is made thick and a part thin, and a slide-out slider (801) is attached to the thin part. With this structure, no step difference occurs when the slide-out slider (801) is pulled out. In addition, it provides support to enable wide sliding. In the slide-out forward rolling of FIG. 14, the roller and the gear are connected in a straight line, and the two can be installed with the roller and gear intersecting.

[0088] Figure 5 shows an example of multiple gears connected in a straight line, with a rolling structure placed between these slider gears (201). At this time, the gear is located on the inner side of the slide-out auxiliary slider (802), and a rack gear is placed on this inner side with a length equal to the sliding length to enable sliding. If the slide-out auxiliary slider (802) does not exist, a rack gear may be placed at a specific point on the slide-out slider (801). Additionally, a motor connected to the gear is provided and connected to a power button to operate it, allowing the slider to be pulled out or retracted. The gear position of the motor is set so that the gums mesh with a specific gear among the straight roller and gear shapes.

[0089] FIG. 15 shows the slide-out slider (801) and the slide-out auxiliary slider (802) combined in a stepped manner.

[0090] FIG. 16 shows an example of a circular slide-out conveyor (803) for overcoming a step difference during slide-out. A circular conveyor belt is preferred, but a straight conveyor belt is also acceptable.

[0091] Power means such as a motor or hydraulic pump and rotation means such as a gear are provided to enable the slider to be pulled in and out, and a rack gear, etc. is placed inside the extension slider. In the case of the gear, a bidirectional gear may be used, or the position of the gear may be changed so that it interacts with the upper rack gear or lower rack gear of the slider when it is extended or retracted.

[0092] A power and rotation means, such as a motor, are provided to enable uniform retraction and retraction of the slider, and multiple expansion sliders form an integrated unit, and retraction occurs by engaging rack gears, etc., inside the expansion sliders, and one or more conveyor belts can move simultaneously with a structure in which an integrated rolling unit is added to the conveyor belt.

[0093] The examples of the present invention do not present all of the inventive concept, and it is obvious that various examples according to the inventive concept are also included within the scope of the present invention.

[0094] The present invention has the potential for industrial manufacturing, production, and sales of mobile devices using flexible displays.
