FOLDABLE ELECTRONIC DEVICE INCLUDING DISPLAY PROTECTION STRUCTURE

BACKGROUND
1. Field

The disclosure relate to a foldable electronic device including a display protection structure.

2. Description of Related Art

Electronic devices have become slimmer and tend to have increased rigidity, enhanced design aspects, and improved functional elements for differentiation. Such electronic devices are evolving to have various shapes, other than the conventional uniform rectangular shape. For example, an electronic device may have a transformable structure which provides convenient portability and allows use of a large-screen display when the electronic device is used. For example, an electronic device may include a foldable electronic device that operates in such a way that at least two housings are folded or unfolded with respect to each other, and various improvements are provided to solve problems caused by a folding structure.

SUMMARY

A foldable electronic device may include a hinge device (e.g., a hinge module, a hinge structure, or a hinge unit), and a first housing (e.g., a first housing structure) and a second housing (e.g., a second housing structure), each of which is connected to the hinge device in a direction facing the hinge device. The first housing may be rotated in a range of 0 degrees to 180 degrees with respect to the second housing via the hinge device, and thus the foldable electronic device may be operated in an in-folding manner or in an out-folding manner. The foldable electronic device may include a flexible display disposed across the first housing and the second housing to be viewed from the outside in a state in which the foldable electronic device is opened approximately 180 degrees.

Because the flexible display should be folded together with the housings, the flexible electronic device may not include a rigid body (e.g., a front window or a window glass) for protecting the flexible display, unlike general bar-type electronic devices. Therefore, the foldable electronic device may be fixed to the housings in a state in which a protective layer (e.g., a polyimide (PI) film and/or ultra-thin glass (UTG)) is disposed on an upper surface of the flexible display, and the edges thereof may be concealed via a separate protection cover (e.g., a protective frame or a decorative member). In an embodiment, a foldable electronic device may include only a flexible display disposed without a protection cover.

However, a foldable electronic device may include, in a folding area, a cut-out space in which a protective frame is cut to provide a degree of freedom in bending of the hinge device according to a folding operation. For example, via the cut-out space, the edges of the flexible display are exposed to not only allow foreign matter to be introduced into the space, but also allow a user to lift the edges of the flexible display arbitrarily with his/her fingers or a sharp tool, and thus the flexible display may be broken or a malfunction may be induced.

The problems to be solved in the disclosure are not limited to the above mentioned problems, and may be variously expanded without departing from the spirit and scope of the disclosure.

According to an aspect of the disclosure, an electronic device includes: a first housing; a second housing; at least one hinge device which connects the first housing and the second housing to be foldable with respect to each other with reference to a folding axis; a hinge housing which receives the at least one hinge device; a flexible display including a first region corresponding to the first housing, a second region corresponding to the second housing, and a folding area which is foldable and connects the first region and the second region; and at least one protective member which is coupled, in an area corresponding to the folding area, to the hinge housing to be rotatable with reference to a rotation axis parallel to the folding axis, the protective member including a material which is at least partially deformable according to a folding operation of the electronic device, wherein the at least one protective member at least partially overlaps at least one edge of the flexible display in the folding area when the flexible display is viewed from above.

The height of the support part may be based on an arrangement in which the at least one protective member is disposed adjacent to the flexible display.

When the electronic device is in a folded state, the height of the support part may be based on an arrangement in which at least a part of a gap disposed between the first housing and the second housing is covered by the support part.

The height of the support part may be based on an arrangement in which the at least one protective member is in contact with the flexible display.

The shaft may be integrally formed with the body.

The body further may include a pin receiving groove to which the shaft is coupled.

The shaft may include a metal material, and is coupled to the body by insert injection molding.

The rotation axis may overlap the folding axis when the upper surface is viewed from above.

The body of the at least one protective member may further include a recess that is lower than the upper surface with reference to the rotation axis.

The electronic device may further include a foreign matter blocking cover extending toward the hinge housing, and coupled to the body.

The foreign matter blocking cover may include a material having a rigidity which is less than a rigidity of the body.

The foreign matter blocking cover may further include a groove provided in an overlapping area, in which the foreign matter blocking cover at least partially overlaps the rotation axis when the upper surface is viewed from above.

The electronic device may include: a first extension part extending from the body toward the first housing, and a second extension part extending from the body toward the second housing.

The first extension part may at least partially overlap the at least one edge of the flexible display from the perspective above the flexible display, and the second extension part may at least partially overlap the at least one edge of the flexible display from the perspective above the flexible display.

The electronic device may further include: a first protection cover disposed on the first housing in the first region with the first extension part interposed between the first protection cover and the first region, such that the first protection cover overlaps the at least one edge of the flexible display; and a second protection cover disposed on the second housing in the second region with the second extension part interposed between the second protection cover and the second region, on the second housing such that the second protection cover overlaps the at least one edge of the flexible display.

The first extension part may include a first guide hole, the first protection cover may include a first guide protrusion protruding toward the first housing in order to be guided to the first guide hole, and the at least one protective member may be configured to be movable such that the first guide protrusion moves along the first guide hole according to a folding and an unfolding operation of the electronic device.

With reference to FIGS. 1A, 1B, 1C, 2A and 2B, the electronic device 100 may include a pair of housings 110 and 120 (e.g., foldable housings) that are rotatably coupled as to allow folding relative to a hinge mechanism (e.g., hinge mechanism 140 in FIG. 1B). In various embodiments, the hinge mechanism (e.g., hinge mechanism 140 in FIG. 1B) may be disposed in the X-axis direction or in the Y-axis direction. In certain embodiments, two or more hinge mechanisms (e.g., hinge mechanism 140 in FIG. 1B) may be arranged to be folded in a same direction or in different directions. According to an embodiment, the electronic device 100 may include a flexible display 130 (e.g., foldable display) disposed in an area formed by the pair of housings 110 and 120.

According to certain embodiments, the pair of housings 110 and 120 are not limited to the shape and combinations illustrated herein, and may be implemented with a combination of other shapes or parts. For example, in certain embodiments, the first side member 113 may be integrally formed with the first rear cover 114, and the second side member 123 may be integrally formed with the second rear cover 124.

According to certain embodiments, in the unfolded state of the electronic device 100, the second side surface 113b of the first side member 113 and the fifth side surface 123b of the second side member 123 may be connected without a gap formed therebetween. According to an embodiment, in the unfolded state of the electronic device 100, the third side surface 113c of the first side member 113 and the sixth side surface 123c of the second side member 123 may be connected without a gap formed therebetween. According to an embodiment, in the unfolded state, the electronic device 100 may be configured such that the combined length of the second side surface 113b and the fifth side surface 123b is longer than the combined length of the first side surface 113a and/or the fourth side surface 123a. In addition, the combined length of the third side surface 113c and the sixth side surface 123c may be configured to be longer than the length of the first side surface 113a and/or the fourth side surface 123a. In various embodiments, in the unfolding state, the device 100 may be configured such that the sum of the lengths of the second side surface 113b and the fifth side surface 123b is shorter than or equal to the length of the first side surface 113a and/or the fourth side surface 123a. In addition, the sum of the lengths of the third side surface 113c and the sixth side surface 123c may be configured to be shorter than or equal to the length of the first side surface 113a and/or the fourth side surface 123a.

According to certain embodiments, the first side member 113 and/or the second side member 123 may be formed of a metal, and may further include a polymer injected into the metal. According to an embodiment, the first side member 113 and/or the second side member 123 may include at least one conductive portion 116 and/or 126 electrically segmented through one or more segmenting portions 1161 and 1162 and/or segmenting 1261 and 1262, which may be formed using a polymer. In this case, the at least one conductive portion may be electrically connected to a wireless communication circuit included in the electronic device 100, and may be used as an antenna operating in at least one designated band (e.g., legacy band).

According to certain embodiments, the first rear cover 114 and/or the second rear cover 124 may be formed of, for example, coated or tinted glass, ceramic, polymer, metal (e.g., aluminum, stainless steel or “STS”, or magnesium), or a combination thereof.

According to certain embodiments, the flexible display 130 may be disposed to extend from the first surface 111 of the first housing 110 across the hinge mechanism (e.g., hinge mechanism 140 in FIG. 1B) to at least a portion of the third surface 121 of the second housing 120. For example, the flexible display 130 may include a first region 130a substantially corresponding to the first surface 111, a second region 130b corresponding to the second surface 121, and a third region 130c (e.g., the bendable region) connecting the first region 130a and the second region 130b and corresponding to the hinge mechanism (e.g., hinge mechanism 140 in FIG. 1B). According to an embodiment, the electronic device 100 may include a first protection cover 115 (e.g., first protection frame or first decoration member) coupled along the periphery of the first housing 110. According to an embodiment, the electronic device 100 may include a second protection cover 125 (e.g., second protection frame or second decoration member) coupled along the periphery of the second housing 120.

Consequently, the periphery of the flexible display 130 may be substantially protected from the outside. According to an embodiment, the electronic device 100 may include a hinge housing 141 (e.g., hinge cover) that is disposed so as to support the hinge mechanism (e.g., hinge mechanism 140 in FIG. 1B). The hinge housing 141 may further be exposed to the outside when the electronic device 100 is in the folded state, and be invisible as viewed from the outside when retracted into a first space (e.g., internal space of the first housing 110) and a second space (e.g., internal space of the second housing 120) when the electronic device 100 is in the unfolded state. In certain embodiments, the flexible display 130 may be disposed to extend from at least a portion of the second surface 112 to at least a portion of the fourth surface 122. In this case, the electronic device 100 may be folded so that the flexible display 130 is exposed to the outside (out-folding scheme).

The electronic device 100 may further include a flash 109 disposed close to the second camera device 108. According to an embodiment, the camera device 105 or 108 may include one or more lenses, an image sensor, and/or an image signal processor. The flash 109 may include, for example, a light emitting diode or a xenon lamp. According to an embodiment, the camera devices 105 and 108 may be arranged so that two or more lenses (e.g., wide-angle lens, super-wide-angle lens, or telephoto lens) and image sensors are positioned on one surface (e.g., first surface 111, second surface 112, third surface 121, or fourth surface 122) of the electronic device 100. In certain embodiments, the camera devices 105 and 108 may include time-of-flight (TOF) lenses and/or an image sensor.

According to certain embodiments, the key input device 106 (e.g., key button) may be disposed on the third side surface 113c of the first side member 113 of the first housing 110. In certain embodiments, the key input device 106 may be disposed on at least one of the other side surfaces 113a and 113b of the first housing 110 and/or the side surfaces 123a, 123b and 123c of the second housing 120.

According to certain embodiments, some of the camera devices 105 and 108 (e.g., first camera device 105) or the sensor module 104 may be disposed to be exposed through the flexible display 130. For example, the first camera device 105 or the sensor module 104 may be arranged in the internal space of the electronic device 100 so as to be in contact with the external environment through an opening (e.g., through hole) formed at least partially in the flexible display 130. In another embodiment, some sensor modules 104 may be arranged in the internal space of the electronic device 100 so as to perform their functions without being visually exposed through the flexible display 130. For example, in this case, the opening of a region of the flexible display 130 facing the sensor module may be not needed.

With reference to FIG. 2B, the electronic device 100 may be operated to remain in an intermediate state through the hinge mechanism (e.g., hinge device 140 in FIG. 1B). In this case, the electronic device 100 may control the flexible display 130 to display different pieces of content on the display area corresponding to the first surface 111 and the display area corresponding to the third surface 121. According to an embodiment, the electronic device 100 may be operated substantially in an unfolded state (e.g., unfolded state of FIG. 1A) and/or substantially in a folded state (e.g., folded state of FIG. 2A) with respect to a specific inflection angle (e.g., angle between the first housing 110 and the second housing 120 in the intermediate state) through the hinge mechanism (e.g., hinge mechanism 140 in FIG. 1B). For example, when a pressing force is applied in the unfolding direction (B direction) in a state where the electronic device 100 is unfolded at a specific inflection angle, through the hinge mechanism (e.g., hinge mechanism 140 in FIG. 1B), the electronic device 100 may be transitioned to an unfolded state (e.g., unfolded state of FIG. 1A). For example, when a pressing force is applied in the folding direction (C direction) in a state where the electronic device 100 is unfolded at a specific inflection angle, through the hinge mechanism (e.g., hinge mechanism 140 in FIG. 1B), the electronic device 100 may be transitioned to a closed state (e.g., folded state of FIG. 2A). In an embodiment, the electronic device 100 may be operated to remain in an unfolded state at various angles (not shown) through the hinge mechanism (e.g., hinge mechanism 140 in FIG. 1B).

FIGS. 1A, 1B, 1C, 2A and 2B illustrate an in-folding scheme in which the first surface 111 of the first housing 110 and the third surface 121 of the second housing 120 face substantially the same first direction (the z-axis direction) when the electronic device 100 is in a flat state or unfolding state, and in which the first surface 111 and the third surface 121 face each other when the electronic device 100 is in a folded state. According to an embodiment, there may be an out-folding scheme in which, the first surface 111 of the first housing 110 and the third surface 121 of the second housing 120 face substantially the same first direction (the z-axis direction) when the electronic device 100 is in a flat state or unfolding state and in which the second surface 112 and the fourth surface 122 face each other when the electronic device 100 is in a folded state.

FIG. 3 is an exploded perspective view of the electronic device according to various embodiments.

With reference to FIG. 3, the electronic device 100 may include a first side member 113 (e.g., first side frame), a second side member 123 (e.g., second side frame), and a hinge mechanism 140 (e.g., hinge module or hinge device) rotatably connecting the first side member 113 and the second side member 123. According to an embodiment, the electronic device 100 may include a first support member 1131 (e.g., first support member) at least partially extending from the first side member 113, and a second support member 1231 at least partially extending from the second side member 123.

According to an embodiment, when the flexible display 130 is viewed from above, the body 410 may be disposed in a third region (e.g., a third region 130c of FIG. 1A) corresponding to the hinge device (e.g., the hinge device 140 of FIG. 1A and/or the hinge housing 141 of FIG. 3). According to an embodiment, in a third region 130c, the body 410 may be disposed to be viewed from the outside. According to an embodiment, when the flexible display 130 is viewed from above, the first extension part 420 may be disposed on at least a portion of a first area (e.g., a first region 130a of FIG. 1A) corresponding to the first housing (e.g., the first housing 110 of FIG. 1A). According to an embodiment, between the flexible display 130 and a first protection cover (e.g., a first protection cover 115 of FIG. 1A), the first extension part 420 may be disposed not to be viewed from the outside. According to an embodiment, when the flexible display 130 is viewed from above, the second extension part 430 may be disposed on at least a portion of a second region (e.g., a second region 130b of FIG. 1A) corresponding to the second housing (e.g., the second housing 120 of FIG. 1A). According to an embodiment, between the flexible display 130 and a second protection cover (e.g., a second protection cover 125 of FIG. 1A), the second extension part 430 may be disposed not to be viewed from the outside. According to an embodiment, when the flexible display 130 is viewed from above, the body 410 may be disposed to at least partially overlap the edges of the flexible display 130.

According to various embodiments, the protective member 400 may be made of a bendable polymer material which can be bent together according to a folding operation of the electronic device (e.g., the electronic device 100 of FIG. 1A). For example, the protective member 400 may be made of at least one material among rubber, silicone, or urethane (e.g., thermoplastic polyurethane (TPU)). According to an embodiment, the protective member 400 may be disposed to be rotatable with reference to the rotation axis X at opposite ends of the hinge housing (e.g.f, the hinge housing 141 of FIG. 3), respectively. According to an embodiment, the rotation axis X may be disposed in parallel with the folding axis (e.g., the folding axis A of FIG. 1A). According to an embodiment, when the flexible display 130 is viewed from above, the rotation axis X may be disposed at a position overlapping the folding axis A. According to an embodiment, the protective member 400 may include a shaft 413 (e.g., a hinge pin) extending from a side surface 412 of the body 410 along the rotation axis X to have a predetermined length. According to an embodiment, the shaft 413 may be rotatably coupled to a shaft receiving groove (e.g., a shaft receiving groove 1413 of FIG. 5) disposed on the hinge housing 141 to be described later. In an embodiment, the rotation axis X may be substituted with an insert-molded metal shaft in the body 410 made of a bendable polymer material.

According to various embodiments, the protective member 400 may include a bending structure for assisting bendability according to a folding operation of the electronic device (e.g., the electronic device 100 of FIG. 1A). For example, in the body, the protective member 400 may include a recess 4111 disposed lower than the upper surface 411. According to an embodiment, when the upper surface 411 is viewed from above, the recess 4111 may be disposed, on the left and right with respect to the rotation axis X, in a symmetrical shape. Therefore, when the side surface 412 of the body 410 is viewed from the outside, the thickness t2 of the body 410 of the protective member 400, in an area including the recess 4111, may be configured to be smaller than the thickness t1 of the body 410, in an area not including the recess 4111.

According to various embodiments, the protective member 400 may include a foreign matter blocking cover 440 additionally coupled to the body 410. According to an embodiment, the foreign matter blocking cover 440 may be coupled to the body 410 via double injection molding.

According to an embodiment, the foreign matter blocking cover 440 is made of a material having rigidity less than that of the body 410 (e.g., a material having a greater elastic force than that of the body 410), in order to help improve bendability of the body 410. According to an embodiment, when the upper surface 411 is viewed from above, the foreign matter blocking cover 440 may include a groove 441 disposed in an area in which the foreign matter blocking cover overlaps the rotation axis X, in order to help improve bendability of the body 410.

According to various embodiments, the protective member 400 may include a first guide hole 421 (or a groove) disposed through the first extension part 420 and a second guide hole 431 (or a groove) disposed through the second extension part 430. According to an embodiment, the first guide hole 421 may be configured in a shape capable of receiving a first guide protrusion (e.g., a first guide protrusion 1151 of FIG. 8) disposed on the first protection cover (e.g., the first protection cover 115 of FIG. 1A). According to an embodiment, the second guide hole 431 may be configured in a shape capable of receiving a second guide protrusion (e.g., a second guide protrusion 1251 of FIG. 8) disposed on the second protection cover (e.g., the second protection cover 125 of FIG. 1A). According to an embodiment, the first guide hole 421 and the second guide hole 431 may be arranged to have a length along the length direction of the body 410. According to an embodiment, the first guide hole 421 and the second guide hole 431, at the time of folding operation of the electronic device (e.g., the electronic device of FIG. 1A), can help the first and the second extension parts 420 and 430 to prevent separation due to a slip phenomenon occurring between the flexible display 130 and the first and the second protection covers 115 and 125, and perform a sliding operation in the predetermined direction.
