[0002] This disclosure relates to an electronic device including a dustproof structure. Background Technology

[0003] Portable electronic devices such as smartphones can offer a variety of functions (such as making calls, playing videos, and searching the web) based on various types of applications. Users may want to use these functions through a wider screen. However, as the screen becomes larger, portability is likely to decrease. Therefore, foldable portable electronic devices have been developed that utilize a foldable structure to increase the portability of portable electronic devices.

[0004] The above information is presented as background information only to aid in understanding this disclosure. It is neither determined nor asserted whether any of the above content is suitable as prior art to this disclosure. Summary of the Invention

[0005] Foldable electronic devices can be configured to rotate via a hinge structure connected to an adjacent housing and to support the housing when the housing rotates at a predetermined angle. Various structures can be arranged regarding the hinge operation of the housing. However, for foldable electronic devices, gaps may form in the folding area, and foreign objects may easily be introduced into these gaps. If a foreign object introduced through the gap is located below the display, the display may be damaged due to hinge operation. Furthermore, if the introduced foreign object is trapped in the hinge structure, normal hinge operation may be impossible.

[0006] The present disclosure aims to at least address the aforementioned problems and / or disadvantages, and to provide at least the advantages described below. Therefore, one aspect of the present disclosure is to provide an electronic device including a dustproof structure capable of preventing foreign objects from being introduced into the foldable electronic device.

[0007] Another aspect of this disclosure is to provide a hinge structure comprising: a first housing; a second housing; a hinge housing disposed between the first housing and the second housing; and a flexible display disposed at least partially on the first housing and the second housing. The first housing and the second housing are foldable or unfoldable based on the hinge housing and include at least one fiber structure disposed on at least a portion of one side of the first housing, said side of the first housing being adjacent to the hinge housing within a predetermined distance.

[0008] Other aspects will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the proposed embodiments.

[0009] According to one aspect of this disclosure, an electronic device is provided. The electronic device includes a dustproof structure according to various embodiments of this disclosure, the dustproof structure sealing the gap between a hinge housing and a housing to prevent foreign objects from being introduced into the electronic device, thereby preventing various types of damage caused by foreign objects.

[0010] Furthermore, by providing a dustproof structure, such as a fiber structure, in the electronic device according to various embodiments of the present disclosure, the dustproof properties can be maintained even under repeated hinge operations.

[0032] The following description, with reference to the accompanying drawings, is provided to aid in a full understanding of the various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to aid understanding, but these are to be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present disclosure. Additionally, for clarity and brevity, descriptions of well-known functions and constructions may be omitted.

[0033] The terms and words used in the following description and claims are not limited to their literal meaning, but are merely the inventor's choice to enable a clear and consistent understanding of this disclosure. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this disclosure is for illustrative purposes only and is not intended to limit the purpose of this disclosure as defined by the appended claims and their equivalents.

[0034] It will be understood that, unless the context explicitly specifies otherwise, the singular form includes the plural indicator. Thus, for example, a reference to “component surface” includes a reference to one or more such surfaces.

[0035] As used herein, terms and phrases such as “have,” “may have,” “include,” or “may include” indicate the presence of features (e.g., numbers, functions, actions, or parts of a component) but do not preclude the presence of additional features.

[0036] As used herein, the phrase “A or B”, “at least one of A and / or B”, or “one or more of A and / or B” can include all possible combinations of the items listed together. For example, “A or B”, “at least one of A and B”, or “at least one of A or B” can indicate all of the following: (1) including at least one A, (2) including at least one B, or (3) including both at least one A and at least one B.

[0037] As used herein, terms such as “first,” “second,” “the first,” or “the second” may modify various components regardless of order and / or importance, and are used to distinguish one component from another without limiting the components. For example, a first user device and a second user device may refer to different user devices regardless of order or importance. For example, without departing from the teachings disclosed herein, a first element may be referred to as a second element, and similarly, conversely, a second element may be referred to as a first element.

[0038] When a component (e.g., the first component) is referred to as being "(operably or communicatively) coupled" / "(operably or communicatively) coupled to" or "connected to" another component (e.g., the second component), it should be understood that any of the aforementioned components can be directly connected to the other component, or can be connected through another component (e.g., the third component). In contrast, when a particular component (e.g., the first component) is referred to as being "directly coupled" or "directly connected" to another component (e.g., the second component), it will be understood that there is no interference from other components (e.g., the third component) between the particular component and the other component.

[0039] As used herein, the phrase “constructed as (or configured)” may be used interchangeably with, for example, “suitable for,” “capable of,” “designed to,” “appropriate for,” “made of,” or “capable of.” The phrase “constructed as” does not necessarily mean only that it is “specifically designed for” in hardware.

Figure 1A This is a perspective view of the electronic device 100 in its first state (e.g., flat or unfolded). Figure 1B This is a perspective view of the electronic device 100 in a second state (e.g., a folded state). Alternatively or additionally, the electronic device 100 may also include a first cover 119 covering the rear portion of the first housing 110 and a second cover 129 covering the rear portion of the second housing 120.

[0045] According to various embodiments of this disclosure, depending on the arrangement, the first housing 110 may be continuous with the second housing 120 (e.g., when the central portion 163 of the display 160 is flattened or when the housing 101 is in an unfolded state), or the first housing 110 may be side-by-side with the second housing 120. Optionally, when the central portion 163 of the display 160 is folded, one surface of the first housing 110 may be arranged to face one surface of the second housing 120.

[0046] The first housing 110 may be formed, for example, at least partially using a metallic material, or at least partially using a non-metallic material. For example, the first housing 110 may be formed using a material with a specific stiffness to support at least a portion of the display 160. A region of the display 160 (e.g., a portion of the first region 161 and the central portion 163 of the display 160) may be disposed on at least a portion of the front surface of the first housing 110. At least a portion of the first housing 110 may be adhered to the first region 161 of the display 160. Optionally, at least a portion of the front edge of the first housing 110 may be adhered to the edge of the first region 161 of the display 160. Optionally, the upper side of the front surface of the first housing 110 may be adhered to one side of the first region 161 of the display 160. In this respect, a first adhesive layer 167a may be at least partially disposed between the first housing 110 and the first region 161 of the display 160. The first housing 110 is at least partially configured to be hollow, or configured such that it forms an empty space by engaging with the first cover 119, so that electronic components required to drive the display 160 (e.g., printed circuit board, at least one processor mounted on the printed circuit board, at least one memory, and components such as a battery) can be provided.

[0047] According to various embodiments of this disclosure, the edges of the first housing 110 (e.g., three edges other than the remaining edge 139 arranged side-by-side with the second housing 120 in the unfolded state of the display 160 of the electronic device 100) may protrude from the bottom surface of the central portion of the housing at a predetermined height to surround at least one side edge of the display 160. Optionally, a sidewall facing at least a portion of the edge of the display 160 may be provided on at least one edge of the first housing 110. The sidewall, at least partially formed on the edge of the first housing 110, may be formed to have a specific height at three edges other than the remaining edge 139 arranged side-by-side with the second housing 120 in the unfolded state of the display 160. The edge 139 of the first housing 110 facing the second housing 120 in the unfolded state of the display 160 may at least partially have a predetermined curvature, thereby allowing at least a portion of the hinge housing 150 to be provided. For example, the edge of the first housing 110 (or the second housing 120) may be recessed along a predetermined direction with curvature. According to various embodiments of this disclosure, in the unfolded state of the display 160, a first step portion 111 and a second step portion 112 may be formed on the edge 139 of the first housing 110 facing the second housing 120. At least a portion of the first hinge structure 200a may be disposed on the first step portion 111. At least a portion of the second hinge structure 200b may be disposed on the second step portion 112.

[0048] According to various embodiments of the present disclosure, depending on the arrangement, in the unfolded state of the display 160, the second housing 120 may be arranged side-by-side with the first housing 110, or at least one surface of the second housing 120 may be arranged side-by-side with a surface of the first housing 110 (e.g., the surface on which the display 160 is disposed). The second housing 120 may be made of the same material as the first housing 110. Since the second housing 120 and the first housing 110 are arranged to be symmetrical in shape (left-right or vertically symmetrical), the front surface of the second housing 120 may support at least a portion of the area of ​​the display 160 other than the area disposed on the housing 110 (e.g., other components of the second region 162 and the central portion 163 of the display 160). According to various embodiments of the present disclosure, at least a portion of the second housing 120 may be made of a different material than the first housing 110 and may be formed to be non-symmetrical in shape (left-right or vertically symmetrical) with the first housing 110. For example, the area of ​​the rear surface of the second housing 120 may be different from the area of ​​the rear surface of the first housing 110.

[0049] At least a portion of the second housing 120 may be adhered to the second region 162 of the display 160. Optionally, the front edge of the second housing 120 may be adhered to the edge of the second region 162 of the display 160. Optionally, the underside of the front surface of the second housing 120 may be adhered to one side of the second region 162 of the display 160. In this respect, the second adhesive layer 167b may be at least partially disposed between the second housing 120 and the second region 162 of the display 160. The second housing 120 may be at least partially configured as a hollow shape (similar to the first housing 110), or may be configured such that electronic components required to drive the display 160 can be disposed in the empty space formed by engagement with the second cover 129.

[0050] According to various embodiments of this disclosure, the edges of the second housing 120 (e.g., three edges other than the remaining edge 149 arranged side-by-side with the first housing 110 in the unfolded state of the display 160) may protrude from the bottom surface of the central portion of the second housing 120 at a predetermined height to surround the other side edges of the display 160. Optionally, on at least one edge of the second housing 120, a sidewall facing at least a portion of the edge of the display 160 may be provided, which is similar to the sidewall formed on the first housing 110. The sidewall at least partially formed on the edge of the second housing 120 may be configured to have a specific height at the three edges other than the remaining edge 149 arranged side-by-side with the first housing 110 in the unfolded state of the display 160.

[0051] The portion of the second housing 120 facing the first housing 110 may at least partially have a predetermined curvature, thereby allowing the hinge housing 150 to be provided. According to various embodiments of the present disclosure, a third step portion 121 and a fourth step portion 122 may be formed on the edge 149 of the second housing 120 adjacent to the first housing 110, with at least a portion of the first hinge structure 200a disposed on the third step portion 121 and at least a portion of the second hinge structure 200b disposed on the fourth step portion 122.

[0052] According to various embodiments of this disclosure, the electronic device 100 may include at least one sensor disposed on one of the first housing 110 or the second housing 120 and associated with the operation of a specific function of the electronic device 100. The sensor may include at least one of, for example, a proximity sensor, an illumination sensor, an iris sensor, an image sensor (or a camera), or a fingerprint sensor. According to various embodiments of this disclosure, at least one of the sensors may be disposed below the display 160 and acquire sensing information along the direction of display on the display 160 via the screen.

[0053] According to various embodiments of this disclosure, depending on the folded or unfolded state of the electronic device 100, the hinge housing 150 may be covered by one of the first housing 110 and the second housing 120 (e.g., in the unfolded state of housing 101), or may be exposed to the outside (e.g., in the folded state of housing 101). For example, as in Figure 1A In this configuration, if the first housing 110 and the second housing 120 are arranged side by side, the hinge housing 150 can be covered by the first housing 110 and the second housing 120. For example, in... Figure 1B In this configuration, if one surface of the first housing 110 and one surface of the second housing 120 are arranged to face each other, the hinge housing 150 may be configured such that at least a portion thereof is exposed to the outside at the side edges of the first housing 110 and the second housing 120 (e.g., the edges of the first housing 110 and the second housing 120 facing each other in the unfolded state). According to various embodiments of this disclosure, at least a portion of the first housing 110 and the second housing 120 may be flexible.

[0054] According to various embodiments of the present disclosure, at least a portion of the display 160 may be flexible. According to embodiments of the present disclosure, the display 160 may include: a first region 161 or an upper region disposed on a first housing 110; a second region 162 or a lower region disposed on a second housing 120; and a central portion 163 or a central region adjacent to the first housing 110 and the second housing 120. According to various embodiments of the present disclosure, the entire display 160 may be flexible. Optionally, at least a portion of the central portion 163 of the display 160 may be flexible. The central portion 163 of the display 160 may be configured such that the first housing 110 and the second housing 120 are not adhered to each other. For example, the central portion 163 of the display 160 may be in a non-adhesive state with at least a portion of the first housing 110 and the second housing 120. The first region 161 of the display 160 may adhere to at least a portion of the first housing 110, and the second region 162 of the display 160 may adhere to at least a portion of the second housing 120. In this regard, the first adhesive layer 167a may be disposed in at least a portion of the region between the display 160 and the first housing 110, and the second adhesive layer 167b may be disposed in at least a portion of the region between the display 160 and the second housing 120. The first adhesive layer 167a and the second adhesive layer 167b may be disposed only on the edges of the first housing 110 and the second housing 120.

[0055] Figure 2 This is a diagram illustrating an example of a hinge structure and a hinge housing of an electronic device according to an embodiment of the present disclosure.

[0056] Reference Figure 2 According to embodiments of this disclosure, the electronic device may include multiple hinge structures. In the illustrated figures, a first hinge structure 200a and a second hinge structure 200b are arranged within a hinge housing 150. Figure 2 In the diagram, state 201 is the view of the hinge housing 150 from above, state 202 is the view of the hinge housing 150 from the side, and state 203 is the view of the hinge housing 150 from the rear. According to various embodiments of this disclosure, three or more hinge structures may be arranged in the hinge housing 150.

[0057] The first hinge structure 200a may be disposed on one side of the hinge housing 150 (e.g., based on the left side of the illustrated figure). The first hinge structure 200a may be coupled to the left side of the first housing 110 and the left side of the second housing 120, and may rotate within a certain range relative to the horizontal axis of the hinge housing 150. The first hinge structure 200a may be arranged symmetrically with respect to the central portion of the hinge housing 150 with respect to the second hinge structure 200b.

[0058] The second hinge structure 200b may be disposed on the other side of the hinge housing 150 (e.g., based on the right side of the illustrated figure). The second hinge structure 200b may be coupled to the right side of the first housing 110 and the right side of the second housing 120, and may rotate within a certain range relative to the horizontal axis of the hinge housing 150. The second hinge structure 200b may be arranged symmetrically with respect to the central portion of the hinge housing 150 with respect to the first hinge structure 200a. The second hinge structure 200b may have the same structure and construction as the first hinge structure 200a, but may be disposed at a different location than the first hinge structure 200a.

[0059] The hinge housing 150 may be configured as a hollow semi-cylindrical shape or a boat shape, with the ends closed, cut along its length. According to various embodiments of this disclosure, the hinge housing 150 may include a flat bottom 151_3 and a first rib 151_1 and a second rib 151_2 formed on both sides of the bottom 151_3 with a predetermined curvature. The first rib 151_1 and the second rib 151_2 may be arranged symmetrically around the bottom 151_3 on both sides. Based on the figures shown, the width of the hinge housing 150 may gradually decrease from the center to the left and right ends. At least one partition wall 158 may be formed inside the hinge housing 150 to separate the internal space of the hinge housing 150. The first hinge structure 200a and the second hinge structure 200b may be at least partially disposed in the separated spaces. On the right and left ends of the hinge housing 150, blocking walls 151a and 151b may be formed, protruding significantly from the surrounding area so that the interior of the hinge housing 150 is not visible from the outside. The hinge housing 150 may be formed using the same material as the first hinge structure 200a or the second hinge structure 200b.

[0060] Figure 3 This is a diagram illustrating a surface of a hinge structure applied to an electronic device according to an embodiment of the present disclosure.

[0061] Reference Figure 3 The hinge structure 200a or 200b can be either the first hinge structure 200a or the second hinge structure 200b described above. The hinge structures 200a and 200b may include a bracket structure 210, an arm structure 220, a gear structure 230, and a support structure 240.

[0062] The support structure 210 can be combined with the arm structure 220 and its central portion is fixed to the hinge housing 150, and the two wings (e.g., rotating supports) are combined with the first housing 110 and the second housing 120.

[0063] One side of the arm structure 220 can be connected to the support structure 210 via fixing members 251 and 252, and the arm structure 220 can have a changing mounting angle while sliding along one side of the support structure 210 using a hinge operation. The arm structure 220 may include a cam structure. The arm structure 220 including the cam structure can be connected to the cam portion 241 (see [link to cam structure]) provided on the support structure 240. Figure 4 The first housing 110 and the second housing 120 are engaged to provide a braking feel during hinged operation.

[0064] Gear structure 230 may be disposed between support structure 210 and arm structure 220. Gear structure 230 can transmit force such that the second housing 120 rotates together when the first housing 110 rotates. In this respect, gear structure 230 may include multiple axial gears and idle gears.

[0065] The support structure 240 may be fixed inside the hinge housing 150 and may provide specific pressure to the arm structure 220. In this regard, the support structure 240 may include one or more elastic bodies and may push the cam portion 241 toward the arm structure 220 based on the elastic force of the elastic bodies. In this way, the cam portion 241 may engage with the rotary cam structure of the arm structure 220 and thus support cam operation.

[0066] As described above, the hinge structure 200a or 200b according to embodiments of the present disclosure may include: a support structure 210, which is coupled to the hinge housing 150 and housings 110 and 120 and supports the folding or unfolding of the display 160 disposed thereon; an arm structure 220, which is connected to the support structure 210 and provides a braking feel; a gear structure 230, which supports the simultaneous operation of the first housing 110 and the second housing 120; and a support structure 240, which supports the arm structure 220 and the shaft of the gear structure 230 is fixed to the support structure 240. Based on these, the hinge structures 200a and 200b can rotate about a virtual axis formed above the surface of the support structure 210 to realize the folding or unfolding of the display 160, and the torsion of the housings 110 and 120 can be suppressed by providing a braking feel based on a cam structure and supporting the simultaneous hinge operation of the housings 110 and 120 based on the gear structure 230. In addition, the hinge structure 200a or 200b can support a specific predetermined angle, such as 30 degrees or 60 degrees (e.g., the angle between the front surface of the first housing 110 and the front surface of the second housing 120), in an installed state, as well as in an unfolded or folded state of the housings 110 and 120.

[0067] Figure 4 This is a diagram showing a first state of some components of an electronic device according to an embodiment of the present disclosure.

[0068] Reference Figure 1A and Figure 4 Some components of the electronic device may include a first hinge structure 200a and a display 160, and the first hinge structure 200a and the display 160 may have a first state (e.g., an unfolded state).

[0069] As described above, the first hinge structure 200a may include a first rotating bracket 211, a second rotating bracket 212, a fixed bracket 213, a first arm portion 221, a second arm portion 222, a gear structure 230, a cam portion 241, a first elastic body 242a, a second elastic body 242b, a first rotating member 231, a second rotating member 232, and a support bracket 243. The gear structure 230 includes an axial gear and a freewheeling gear for the first rotating member 231 and the second rotating member 232. The first rotating bracket 211 can be connected to the first arm portion 221 via a first fixing member 251. The second rotating bracket 212 can be connected to the second arm portion 222 via a second fixing member 252.

[0070] When the first rotating bracket 211 and the second rotating bracket 212 are in the deployed state, the display 160 can remain in the deployed state. The first arm 221 can rotate within a specific angular range based on the first rotating member 231. The second arm 222 can rotate within a specific angular range based on the second rotating member 232. The first rotating bracket 211 can rotate relative to the first virtual axis 11 within the same or similar angular range as the first arm 221. The second rotating bracket 212 can rotate relative to the second virtual axis 12 within the same or similar angular range as the second arm 222. The first virtual axis 11 can be configured to be higher than the first rotating member 231 in the direction toward the display 160. The second virtual axis 12 can be configured to be higher than the second rotating member 232 in the direction toward the display 160. The distance between the first virtual axis 11 and the second virtual axis 12 can be shorter than the distance between the first rotating member 231 and the second rotating member 232. According to various embodiments of this disclosure, the first virtual axis 11 and the second virtual axis 12 can be formed side-by-side on a horizontal axis. According to embodiments of this disclosure, the first virtual axis 11 and the second virtual axis 12 may be formed on the same layer as the display 160, or formed above the display 160 (e.g., in the air above the display 160).

[0071] When the first rotating bracket 211 and the second rotating bracket 212 are in the deployed state, the first bracket body 211_1 of the first rotating bracket 211 and the second bracket body 212_1 of the second rotating bracket 212 can be arranged side by side. According to an embodiment of the present disclosure, the upper surface of the first bracket body 211_1 and the upper surface of the second bracket body 212_1 can be arranged in the same manner and facing upwards based on the figures shown. According to an embodiment of the present disclosure, when the first rotating bracket 211 and the second rotating bracket 212 are in the deployed state, the first arm 221 and the second arm 222 can also be arranged side by side. Therefore, the first basic body 221_1 of the first arm 221 and the second basic body 222_1 of the second arm 222 can be arranged to face the same direction (e.g., upwards based on the figures shown). Therefore, the first bracket body 211_1, the second bracket body 212_1, the first basic body 221_1 and the second basic body 222_1 can all be arranged side by side based on a horizontal axis and arranged to face upwards based on the figures shown. The first support body 211_1, the second support body 212_1, the first basic body 221_1, and the second basic body 222_1 can support the rear surface of the display 160 without any height difference.

[0072] According to various embodiments of this disclosure, a predetermined gap Gap_1 may be formed with hinge structures 200a and 200b at the curved central portion of the display 160. An adhesive layer may be disposed in a peripheral region (e.g., a first region 161 or a second region 162) other than the central portion 163 of the display 160.

[0073] Figure 5 This is an exploded perspective view illustrating some components of an electronic device according to an embodiment of the present disclosure.

[0074] Reference Figure 5 The electronic device 100 according to embodiments of the present disclosure may include a first housing 110, a second housing 120, a hinge housing 150, a first hinge structure 200a, a second hinge structure 200b, a first dustproof structure 310, a second dustproof structure 320, a third dustproof structure 330, and a fourth dustproof structure 340. Optionally, as Figure 1A As described above, displays may also be provided on the first housing 110 and the second housing 120.

[0075] The first housing 110 may include an upper surface (e.g., a surface facing the y-axis) on which a portion of the display is disposed, sidewalls, and a rear surface supporting the upper surface (e.g., a surface facing the -y-axis). A recessed or cut-in portion 110_1 may be formed in at least a portion of the upper surface, and a device element associated with the driving electronics 100 (e.g., at least one of a printed circuit board, battery, at least one sensor, speaker, microphone, camera, antenna, or processor) may be disposed in the portion 110_1. On one side of the first housing 110, for example, on an edge in the -z-axis direction, a first stepped portion 111 for accommodating a portion of the first hinge structure 200a and a second stepped portion 112 for accommodating a portion of the second hinge structure 200b may be formed. The first stepped portion 111 and the second stepped portion 112 may be disposed adjacent to a first curved portion 115 located at the edge in the -z-axis direction.

[0076] The first housing 110 may include sidewalls facing, for example, three directions (e.g., x, -x, and z-axis directions), and a first bend 115 may be formed on the surface facing the -z-axis direction, relating to engagement with the hinge housing 150. The first bend 115 may include a bend that gradually curves from the z-axis to the -z-axis direction and then towards the -y-axis direction. When viewed along the y-axis to the -y-axis direction, the first bend 115 may have a concave shape. The curvature of the first bend 115 may correspond to the curvature of at least a portion of the outer wall of the hinge housing 150. By hinge operation, the first bend 115 may be configured to overlap the hinge housing 150 at least partially or with a predetermined gap. A first dustproof structure 310 may be provided on at least a portion of the first bend 115. For example, the first dustproof structure 310 may be provided on a surface traversing the first bend 115 along the x-axis to -x-axis direction. According to various embodiments of the present disclosure, at least a portion of the first dustproof structure 310 may be disposed at the end edge of the first curved portion 115 of the first housing 110, and the end edge faces the second curved portion 125 of the second housing 120 when the electronic device 100 is in the unfolded state.

[0077] Similar to the first housing 110, the second housing 120 may include an upper surface (e.g., a surface facing the y-axis) on which a portion of the display is disposed, sidewalls, and a rear surface supporting the upper surface (e.g., a surface facing the -y-axis). In at least a portion of the upper surface, a recessed or cut-in housing portion 120_1 may be formed, and in the housing portion 120_1, device elements associated with the driving electronics 100 (e.g., at least one of a printed circuit board linked to a configuration disposed in the first housing 110, an additional battery, at least one sensor, a speaker, at least one microphone, a camera, an antenna, or an additional processor) may be disposed. On one side of the second housing 120, for example, on one edge in the z-axis direction, a third stepped portion 121 may be formed for accommodating another portion of the first hinge structure 200a, and a fourth stepped portion 122 may be formed for accommodating another portion of the second hinge structure 200b. The third stepped portion 121 and the fourth stepped portion 122 may be disposed adjacent to a second curved portion 125 located at the edge in the z-axis direction.

[0078] The second housing 120 may include sidewalls facing, for example, three directions (e.g., x, -x, and -z axes), and a second bend 125 may be formed on the surface facing the z-axis direction, relating to engagement with the hinge housing 150. The second bend 125 may include a bend that gradually curves from the -z axis towards the z-axis direction and then towards the -y axis direction. When viewed along the y-axis direction to the -y-axis direction, the second bend 125 may have a concave shape. The second bend 125 may be symmetrically arranged with respect to an imaginary line traversing the -x and x axes relative to the first bend 115. Similar to the first bend 115, the curvature of the second bend 125 may correspond to the curvature of the outer wall of at least a portion of the hinge housing 150. At least a portion of the hinge housing 150 may be hingedly mounted on the second bend 125. A second dustproof structure 320 may be provided on at least a portion of the second bend 125. For example, the second dustproof structure 320 may be disposed on a surface that traverses the second bend 125 along the x-axis to -x-axis direction. According to various embodiments of this disclosure, at least a portion of the second dustproof structure 320 may be disposed at the end edge of the first housing 110 facing the second housing 120 in the deployed state of the electronic device 100. Therefore, in the deployed state of the electronic device 100, the first dustproof structure 310 and the second dustproof structure 320 may be arranged side-by-side on the first bend 115 and the second bend 125 based on the x-axis (or based on the -x-axis).

[0079] The hinge housing 150 may be disposed between the first housing 110 and the second housing 120, and may be configured such that at least a portion thereof is exposed to the outside or covered by the first housing 110 and the second housing 120 by the hinge operation of the electronic device 100. For example, when the electronic device 100 is in the unfolded state, the hinge housing 150 may be disposed inside the first bend 115 of the first housing 110 and the second bend 125 of the second housing 120, thereby not being exposed to the outside. When the electronic device 100 is in the folded state, as the first housing 110 and the second housing 120 become folded parts, at least a portion of the hinge housing 150 may be configured to be visible from the outside. As described above... Figure 2 As described above, the hinge housing 150 can be configured to be hollow, thereby housing the first hinge structure 200a and the second hinge structure 200b.

[0080] Figure 6 This is a diagram illustrating an example of a hinge housing according to an embodiment of the present disclosure.

[0081] Reference Figure 6 The hinge housing 150 may include a first hinge mounting portion 150_1 on which a first hinge structure 200a is mounted, and a second hinge mounting portion 150_2 on which a second hinge structure 200b is mounted. The hinge housing 150 may also include a space 150_3 between the first hinge mounting portion 150_1 and the second hinge mounting portion 150_2. At least one first boss 150_1a, which is coupled to the first hinge structure 200a, may be provided on the first hinge mounting portion 150_1, and at least one second boss 150_2a, which is coupled to the second hinge structure 200b, may be provided on the second hinge mounting portion 150_2. After the first hinge structure 200a is coupled to the first boss 150_1a, the first hinge structure 200a may be fixed to the first hinge mounting portion 150_1 by a coupling member (e.g., a screw). Similarly, after the second hinge structure 200b is attached to the second boss 150_2a, the second hinge structure 200b can be fixed to the second hinge mounting portion 150_2 by a connecting member. The empty space 150_3 may include a space formed by the sidewalls provided in the region of the first hinge mounting portion 150_1 and the sidewalls provided in the region of the second hinge mounting portion 150_2. In the empty space 150_3, wires for electrically connecting electronic components provided in the first housing 110 and electronic components provided in the second housing 120 may be provided. In this respect, at least a portion of the structure forming the empty space 150_3 may include a channel (hole or slot) so that wires for connecting the first housing 110 and the second housing 120 can be provided.

[0082] The third dustproof structure 330 may be disposed on one side of the first hinge mounting portion 150_1. According to embodiments of this disclosure, the third dustproof structure 330 may be disposed in a region of the space of the first hinge mounting portion 150_1 that at least partially overlaps (or is adjacent within a predetermined distance) the region on which the first hinge structure 200a is disposed. For example, the third dustproof structure 330 may be disposed on the edge of the first hinge mounting portion 150_1 in the -x-axis direction. Examples of the third dustproof structure 330 may include a fiber structure arranged along the y-axis direction or a fiber structure arranged along the x-axis direction. At least a portion of the third dustproof structure 330 may also include a resilient structure.

[0083] A fourth dustproof structure 340 may be disposed on one side of the second hinge mounting portion 150_2. According to embodiments of this disclosure, during the placement of the second hinge structure 200b on the second hinge mounting portion 150_2, the fourth dustproof structure 340 may be disposed in an area at least partially overlapping with the second hinge structure 200b (or in an area adjacent to the second hinge structure 200b within a predetermined distance). For example, the fourth dustproof structure 340 may be disposed on the edge of the second hinge mounting portion 150_2 in the x-axis direction. Similar to the third dustproof structure 330, the fourth dustproof structure 340 may include a fiber structure arranged along the y-axis direction or a fiber structure arranged along the -x-axis direction. At least a portion of the fourth dustproof structure 340 may also include a resilient structure.

[0084] Figure 7 This is a diagram illustrating an example of a dustproof structure according to an embodiment of the present disclosure.

[0085] Reference Figure 7 The first dustproof structure 310 (or the second dustproof structure 320, the third dustproof structure 330, and the fourth dustproof structure 340) may include a fiber portion 312 (or fiber bundle) and a substrate portion 311. The substrate portion 311 may be formed into a plate shape with a predetermined thickness using materials such as plastic, polymer, or fiber. The fiber portions 312 may be woven and arranged on the substrate portion 311 in a predetermined arrangement. The substrate portion 311 may be configured to have a predetermined width and length. For example, the length of the substrate portion 311 may have a horizontal relationship with the first bend 115 and the second bend 125 formed in the first housing 110 and the second housing 120 (e.g., based on...). Figure 5 The length corresponds to the length along the -x axis and the direction transverse to the x axis. The width of the substrate portion 311 may have a dimension corresponding to a predetermined width of the edges of the first curved portion 115 and the second curved portion 125. According to various embodiments of the present disclosure, an adhesive member (e.g., double-sided tape or liquid adhesive material) may be disposed below the substrate portion 311 to secure the substrate portion 311 to the first curved portion 115 and the second curved portion 125.

[0086] The fiber portion 312 may be composed of multiple aggregates comprising multiple fibers, and may include portions in which each aggregate is inserted into a capsule or aperture 710 of a predetermined pattern disposed in the substrate portion 311. One aggregate may be inserted into and fixed in one capsule or aperture 710. One aggregate may utilize a predetermined number of fiber components, and generally, each aggregate may utilize the same or similar number of fiber components. According to various embodiments of the present disclosure, the number of fibers constituting each aggregate may vary depending on the size or shape or pattern arrangement of the capsule or aperture 710. At least a portion of the lower end of the aggregate of the fiber portion 312 may be inserted into the substrate portion 311, or may protrude below the substrate portion 311. The pattern of the capsule or aperture 710 into which the aggregate of the fiber portion 312 of the substrate portion 311 is inserted and fixed may have various arrangements, such as a zigzag pattern arrangement, a matrix or lattice arrangement, a mixture of lattice and zigzag patterns, a random arrangement, etc. According to embodiments of the present disclosure, the pattern of the capsule or aperture 710 may include an uneven pattern.

[0087] The polymer of the fiber portion 312 can be at least partially fixed to the substrate portion 311, and the remaining portion of the polymer can be arranged upward (along the y-axis direction) based on the upper surface of the substrate portion 311. The lower portion of the polymer of the fiber portion 312 (e.g., the portion disposed relatively close to the substrate portion 311) can be assembled into a sac or hole 710 formed on the substrate portion 311 for insertion and fixation, and the upper portion of the polymer (the portion disposed relatively away from the substrate portion 311) can be arranged at irregular intervals with adjacent fibers. The height of the upper surface of the fiber portion 312 can be formed to have a generally predetermined height. Since the fiber portion 312 is configured such that the lower portion is assembled to the substrate portion 311 and the upper portion is dispersed, the overall shape can be arranged as an inverted cowl (wide side upward).

[0088] The aforementioned first dustproof structure 310 can be configured to have a predetermined height above the substrate portion 311, as in state 701. Then, if the first dustproof structure 310 is disposed on the first curved portion 115 and the hinge housing 150 is disposed on the first dustproof structure 310, at least a portion of the first dustproof structure 310 can have at least a portion of its upper surface curved, as in state 703 (the fibers of the fiber portion 312 are configured to be curved Δ(H1-H2)). Even if the upper part of the fiber portion 312 of the first dustproof structure 310 is curved (as in state 703, the fibers of the fiber portion 312 are intertwined), the space between the fibers can be closed. Furthermore, the space between the hinge housing 150 and the first curved portion 115 and the second curved portion 125 can also be closed. Therefore, even if the space between the first curved portion 115 and the second curved portion 125 and the hinge housing 150 is deformed by the hinge operation of the hinge housing 150, the space can be closed by the first dustproof structure 310, which prevents foreign objects from being introduced from the outside. The height of the fiber section 312 can vary depending on the dimensions of the space between the hinge housing 150 and the first bend 115 and the second bend 125. The number of fibers constituting the polymer of the fiber section 312 can be configured such that, after being arranged on the first bend 115 and the second bend 125, the space between the fibers is closed by compression from the hinge housing 150. Additionally, the number of fibers constituting a polymer can vary depending on the thickness (or diameter) of the fibers. Optionally, even if the hinge operation of the electronic device 100 is performed a predetermined number of times or more (e.g., greater than or equal to 20,000 times), the material, elasticity, and diameter of the fibers that will maintain the original shape of the fiber section 312 can be determined, and based on this determination, the number of fibers assembled into a capsule or aperture 710 can be determined. At least one of various fibers (such as synthetic or natural fibers, optical fibers, and glass fibers) can be used as the fiber of the fiber section 312, and mixed fibers can be used as needed.

[0089] Figure 8 This is a diagram illustrating an example of a housing in an electronic device according to an embodiment of the present disclosure that incorporates a dustproof structure.

[0090] Reference Figure 8 The electronic device 100 may include a first housing 110, a second housing 120, and a hinge housing 150. Additionally, as described above... Figures 1A to 5 As described herein, the electronic device 100 may also include a display, a hinge structure, and at least one device element related to the use of the electronic device.

[0091] The first bend 115 may be formed on one side of the first housing 110. For example... Figure 5As shown, the first bend 115 may have a predetermined curvature on one side edge of the first housing 110 and may have an etched shape. The shape of the first bend 115 may correspond to at least a portion of the shape of the hinge housing 150. The first end 117_1 (or edge) (e.g., the end in the -z-axis direction) of the first bend 115 may be configured to face the second end 127_1 (or edge) (e.g., the end in the z-axis direction) of the second bend 125. The first dustproof structure 310 may be disposed adjacent to the first end 117_1 of the first bend 115 facing the second end 127_1 of the second bend 125. In this respect, a first structural mounting portion 115a on which the first dustproof structure 310 is to be mounted may be formed at the first end 117_1 of the first bend 115. The first structural mounting portion 115a may be formed in a stepped shape on the first end 117_1 of the first bend 115. The first structural mounting portion 115a is recessed relative to the surroundings, and the recessed shape may have a specific curvature. An adhesive component for securing the first dustproof structure 310 may be disposed on one surface of the first structure mounting portion 115a.

[0092] A second bend 125, facing the first bend 115, may be formed on one side of the second housing 120. For example... Figure 5 As shown, the second bend 125 may have a predetermined curvature on one side edge of the second housing 120 and may have an etched shape. The shape of the second bend 125 may correspond to a portion of the shape of the rear surface of the hinge housing 150. The second end 127_1 of the second bend 125 (e.g., the end in the z-axis direction) may be configured to face the first end 117_1 (or edge) of the first bend 115 (e.g., the end in the -z-axis direction). Therefore, if the first end 117_1 of the first bend 115 and the second end 127_1 of the second bend 125 are arranged to face each other, the shapes of the first bend 115 and the second bend 125 may correspond to at least a portion of the shape of the hinge housing 150. For example, the shapes of the first bend 115 and the second bend 125 may be formed to correspond to at least a portion of the shape of the rear surface of the hinge housing 150.

[0093] The second dustproof structure 320 may be disposed adjacent to the second end 127_1 of the second curved portion 125 facing the first end 117_1 of the first curved portion 115. Since the second dustproof structure 320 is located at the second end 127_1 of the second curved portion 125, if the first curved portion 115 and the second curved portion 125 are arranged to at least partially face each other, the first dustproof structure 310 and the second dustproof structure 320 may be arranged adjacent to each other and side-by-side. In this respect, a second structural mounting portion 125a on which the second dustproof structure 320 is to be mounted may be formed at the second end 127_1 of the second curved portion 125. The second structural mounting portion 125a may be formed in a stepped shape on the second end 127_1 of the second curved portion 125, similar to the first structural mounting portion 115a. The second structural mounting portion 125a may be recessed relative to its surroundings, and the recessed shape may have a specific curvature. The second structural mounting portion 125a may be configured to have the same or similar shape as the first structural mounting portion 115a. An adhesive component for securing the second dustproof structure 320 may be disposed on one surface of the second structure mounting portion 125a.

[0094] As shown in the figure, the rear surface of the hinge housing 150 can be disposed on the first dustproof structure 310 and the second dustproof structure 320. When the electronic device 100 is in the unfolded (open) state, one side surface of the first housing 110 (the side provided with the first curved portion 115) and one side surface of the second housing 120 (the side surface provided with the second curved portion 125) can be arranged to face each other. Therefore, the fibrous portions disposed in the first dustproof structure 310 and the second dustproof structure 320 can be arranged to face the y-axis direction. The upper ends of the fibrous portions of the first dustproof structure 310 and the second dustproof structure 320 can be pressed by the rear surface of the hinge housing 150, so the fibrous portions can be arranged to bend along a specific direction. When the electronic device 100 is in the unfolded state, the entire upper surface (or an upper surface greater than or equal to a predetermined proportion) of the first dustproof structure 310 and the second dustproof structure 320 can be bent by the rear surface of the hinge housing 150.

[0095] When the electronic device 100 is in a folded (closed) state, the rear surfaces of the first housing 110 and the second housing 120 can be positioned facing each other. Therefore, the first dustproof structure 310 can be positioned facing the edge of the hinge housing 150 in the -z-axis direction, and the second dustproof structure 320 can be positioned facing the edge of the hinge housing 150 in the z-axis direction. The first dustproof structure 310 can close the gap between the first housing 110 and the hinge housing 150, and the second dustproof structure 320 can close the gap between the second housing 120 and the hinge housing 150, which prevents foreign objects from being introduced through the gaps (or cracks) between the first housing 110 and the second housing 120 and the hinge housing 150. When the first dustproof structure 310 faces one side edge of the hinge housing 150, the fibrous portion provided on the upper part of the first dustproof structure 310 in the y-axis direction can remain upright, and the fibrous portion provided on the lower part of the first dustproof structure 310 in the y-axis direction can be bent. The vertical arrangement of the second dustproof structure 320 can be the same as that of the first dustproof structure 310. In the first dustproof structure 310 and the second dustproof structure 320, the number of fibers or the density of the polymer per unit area (or density per predetermined area) can be the same or similar to each other. According to various embodiments of this disclosure, the density of the polymer disposed in the first dustproof structure 310 and the second dustproof structure 320 can be formed differently depending on the location. For example, the density of the first dustproof structure 310 is greater closer to the first end 117_1 of the first bend 115. Alternatively, the density of the first dustproof structure 310 is smaller closer to the first end 117_1 of the first bend 115.

[0096] Figure 9 This is a diagram illustrating an example of a housing in an electronic device according to an embodiment of the present disclosure that incorporates a dustproof structure.

[0097] Reference Figure 9 The electronic device 100 may include a first housing 110, a second housing 120, and a hinge housing 150. Additionally, as described above in Figures 1 to 120... Figure 5 As described herein, the electronic device 100 may also include a display, a hinge structure, and at least one device element related to the use of the electronic device.

[0098] A first bend 115 may be formed on one side of the first housing 110. The first bend 115 may have a predetermined curvature on one side edge of the first housing 110 and may have an etched shape; however, at least a portion of the shape of the first bend 115 may have a shape corresponding to at least a portion of the shape of the rear surface of the hinge housing 150. A third end 117_2 (or edge) (e.g., an end in the -z-axis direction) of the first bend 115 may be positioned facing a fourth end 127_2 (or edge) (e.g., an end in the z-axis direction) of the second bend 125. A first dustproof structure 310 may be disposed adjacent to the third end 117_2 of the first bend 115 facing the fourth end 127_2 of the second bend 125. The third end 117_2 of the first bend 115 may include a first track protrusion 116 projecting from the -y-axis direction along the y-axis direction. The first track protrusion 116 may be formed to correspond to the longitudinal direction of the first dustproof structure 310 (e.g., a direction traversing from the x-axis to the -x-axis). A third structural mounting portion 115b, on which the first dustproof structure 310 is to be mounted, may be formed at the third end 117_2 of the first curved portion 115 adjacent to the first track protrusion 116. The third structural mounting portion 115b may have a track groove shape etched along the -y-axis at the third end 117_2. The third structural mounting portion 115b may be formed along the longitudinal direction of the first track protrusion 116. An adhesive member (or adhesive tape, adhesive material) may be provided between the bottom surface of the track groove of the first dustproof structure 310 and the third structural mounting portion 115b. At least a portion of the outer ends of the third end 117_2 and the first track protrusion 116 may be rounded.

[0099] The second bend 125 may be formed on one side of the second housing 120. The second bend 125 may be structurally opposite to the first bend 115 described above, and if the third end 117_2 of the first bend 115 and the fourth end 127_2 of the second bend 125 are arranged to face each other, at least a portion of the shape formed by the first bend 115 and the second bend 125 may be formed to correspond to at least a portion of the rear surface of the hinge housing 150. The fourth end 127_2 of the second bend 125 may include a second track protrusion 126 protruding from the -y-axis direction along the y-axis direction. The second track protrusion 126 may be formed to have a shape similar to the first track protrusion 116. The fourth structural mounting portion 125b on which the second dustproof structure 320 is to be mounted may be formed at the fourth end 127_2 of the second bend 125 adjacent to the second track protrusion 126. The fourth structural mounting portion 125b may have a track groove shape etched along the -y-axis direction at the fourth end 127_2. An adhesive component (or adhesive tape, adhesive material) may be disposed between the bottom surface of the track groove of the second dustproof structure 320 and the fourth structure mounting part 125b. At least a portion of the outer ends of the fourth end 127_2 and the second track protrusion 126 may be rounded.

[0100] When the electronic device 100 is in the unfolded (open) state, the third end 117_2 and the fourth end 127_2 can be arranged to face each other. Therefore, the rounded outer ends of the third end 117_2 and the fourth end 127_2 face each other and form a rounded groove of a predetermined depth in the y-axis direction. The rounded groove along the y-axis direction can prevent the body from being stuck between the first housing 110 and the second housing 120 during the holding of the electronic device 100. Since the third structure mounting portion 115b and the fourth structure mounting portion 125b are formed flat, the fiber portion of the first dustproof structure 310 provided at the third structure mounting portion 115b and the fiber portion of the second dustproof structure 320 provided at the fourth structure mounting portion 125b can stand upright side by side in the y-axis direction and can be configured to be at least partially and uniformly bent through the rear surface of the hinge housing 150.

[0101] When the electronic device 100 is in a folded (closed) state, the third end 117_2 can be disposed adjacent to the edge of the hinge housing 150 in the -z-axis direction. Therefore, the first portion 310a of the first dustproof structure 310 disposed at the third end 117_2 can remain upright inside the electronic device 100, and the second portion 310b of the first dustproof structure 310 can be configured to bend by facing the hinge housing 150. In this case, due to the first track protrusion 116, the second portion 310b can be configured to bend along the y-axis direction. In the folded state, since the first track protrusion 116 is disposed below the first dustproof structure 310 in the -y-axis direction, the first dustproof structure 310 can be prevented from being at least partially observed through the gap between the first housing 110 and the hinge housing 150. According to various embodiments of the present disclosure, the polymer density of the fibers disposed in the first portion 310a and the polymer density of the fibers disposed in the second portion 310b can be different from each other. For example, the polymer density of the fibers disposed on the second portion 310b can be made higher than that of the fibers disposed on the first portion 310a, thereby more firmly preventing the introduction of external foreign objects into the electronic device 100. According to various embodiments of the present disclosure, the polymer density of the fibers in the first portion 310a and the second portion 310b of the first dustproof structure 310 is the same, but the fibers disposed on the second portion 310b are pushed by the compression of the hinge housing 150 against the fibers disposed on the first portion 310a, and the density of the fibers disposed on the first portion 310a can be increased accordingly. According to various embodiments of the present disclosure, at least a portion of the first portion 310a of the first dustproof structure 310 can remain upright and thus can be used to support the second portion 310b. In the second portion 310b of the first dustproof structure 310, since the arrangement is changed by the hinge housing 150 and the density of the fibers in the predetermined space is increased, the second portion 310b can be used to firmly block the gap between the hinge housing 150 and the first housing 110.

[0102] When the electronic device 100 is in a folded (closed) state, the fourth end 127_2 can be disposed adjacent to the edge of the hinge housing 150 in the z-axis direction. Therefore, the third portion 320a of the second dustproof structure 320 disposed at the fourth end 127_2 can remain upright inside the electronic device 100, and the fourth portion 320b of the second dustproof structure 320 can be configured to be bent by facing the hinge housing 150. The second dustproof structure 320 can be disposed in a similar or identical state to the first dustproof structure 310, and at least a portion of the second dustproof structure can be covered so that it is not visible from the outside through the second track protrusion 126. According to various embodiments of this disclosure, the polymer density of the fibers disposed in the third portion 320a and the polymer density of the fibers disposed in the fourth portion 320b can be different from each other. For example, the polymer density of the fibers disposed in the fourth portion 320b can be formed to be higher than the polymer density of the fibers disposed in the third portion 320a, thereby more firmly preventing the introduction of external foreign objects into the electronic device 100. Similar to the first dustproof structure 310, the second dustproof structure 320 can be used to support the fourth part 320b, while the third part 320a remains upright and the arrangement of the fourth part 320b is changed. In the fourth part 320b, the arrangement can be changed by contact with the hinge housing 150, and the density of fibers in a specific space can be increased accordingly, thereby firmly blocking the gap between the hinge housing 150 and the second housing 120.

[0103] According to various embodiments of this disclosure, the polymer density of the fibers disposed in the third portion 320a and the polymer density of the fibers disposed in the fourth portion 320b may be different from each other. For example, similar to the first dustproof structure 310, the polymer density of the fibers disposed in the fourth portion 320b may be formed to be higher than the polymer density of the fibers disposed in the third portion 320a. Optionally, the polymer density of the fibers in the third portion 320a and the fourth portion 320b of the second dustproof structure 320 may be the same, but the fibers disposed in the fourth portion 320b may push the fibers disposed in the third portion 320a by the compression of the hinge housing 150, and the density of the fibers disposed in the third portion 320a may be increased accordingly.

[0104] Figure 10 This is a diagram illustrating at least a portion of the cut surface construction of a component of an electronic device employing a dustproof structure according to an embodiment of the present disclosure. Figure 11 It is shown in Figure 10 A diagram showing a portion of a dustproof structure according to an embodiment of the present disclosure disposed in the cut surface.

[0105] Reference Figure 10 and Figure 11The electronic device 100 may include a first housing 110, a second housing 120, a hinge housing 150, a second hinge structure 200b (or a first hinge structure), a display 160, a first dustproof structure 310, and a second dustproof structure 320. In the illustrated figures, the second hinge structure 200b is shown in cross-section by cutting one side of the electronic device 100, and the first hinge structure may be shown in cross-section depending on the cutting position. According to various embodiments of this disclosure, the electronic device 100 may further include at least one of a first adhesive member 310_1 disposed between the first dustproof structure 310 and the first housing 110, and a second adhesive member 320_1 disposed between the second dustproof structure 320 and the second housing 120.

[0106] When the electronic device 100 is in the unfolded (open) state, the display 160 can have a generally flat state. A second hinge structure 200b can be disposed below the display 160. The second hinge structure 200b can be housed within a hinge housing 150. The hinge housing 150 can be configured to be covered by one side edge of the first housing 110 and one side edge of the second housing 120. The first dustproof structure 310 can be as described above... Figure 9 The second dustproof structure 320 is disposed on one side edge of the first housing 110 as described above. Figure 9 The first housing 110 may include a third structural mounting portion 115b and a first track protrusion 116, with a first dustproof structure 310 mounted on the third structural mounting portion 115b. The second housing 120 may include a fourth structural mounting portion 125b and a second track protrusion 126, with a second dustproof structure 320 mounted on the fourth structural mounting portion 125b. The widths of the first track protrusion 116 and the second track protrusion 126 may be, for example, from 0.05 mm to 1 mm (e.g., 0.25 mm). The widths of the first track protrusion 116 and the second track protrusion 126 may vary depending on the dimensions of the electronic device 100. Based on the y-axis, the heights of the first track protrusion 116 and the second track protrusion 126 may be configured to be lower than the heights of the first dustproof structure 310 and the second dustproof structure 320.

[0107] When the electronic device 100 is in a folded (closed) state, the display 160 may have a folded state at its central portion. The first support member 161a and the second support member 161b, disposed below the display 160 to support it, are separate and can be arranged in an upright state in the y-axis direction. The first dustproof structure 310 may be configured to face one side edge (the edge in the x-axis direction) of the hinge housing 150, and the second dustproof structure 320 may be configured to face the other side edge (the edge in the -x-axis direction) of the hinge housing 150. Therefore, some of the fibrous portions of the first dustproof structure 310 may remain upright, while other fibrous portions may be configured to be bent while facing one side edge of the hinge housing 150. Some of the fibrous portions of the second dustproof structure 320 may remain upright, while other fibrous portions may be bent while facing the other side edge of the hinge housing 150. The width of the bent first dustproof structure 310 or second dustproof structure 320 may, for example, be greater than or equal to 0.2 mm. The width of the first dustproof structure 310 or the second dustproof structure 320 may vary depending on the size of the electronic device 100 or the size of the gap between the first housing 110, the second housing 120 and the hinged housing 150. Optionally, the width of the first dustproof structure 310 or the second dustproof structure 320 may vary depending on the material or the vertical length of the base plate portion of the dustproof structure.

[0108] According to various embodiments of this disclosure, a first display protection member 162a for protecting the display 160 and maintaining its flatness may be disposed between the display 160 and the first support member 161a. Similarly, a second display protection member 162b for protecting the display 160 and maintaining its flatness may be disposed between the display 160 and the second support member 161b. The first support member 161a and the first display protection member 162a may be configured as one unit. Similarly, the second support member 161b and the second display protection member 162b may also be configured as one unit.

[0109] Figure 12 This is a diagram illustrating an example of the form in which foreign matter enters in a foldable electronic device according to an embodiment of the present disclosure. Figure 13 This is a diagram showing a portion of a cross-section used to describe the form of foreign matter inflow in a foldable electronic device according to an embodiment of the present disclosure.

[0110] Reference Figure 12 and Figure 13The electronic device 100 may have a channel through which foreign objects are to be introduced at one side edge of its folded portion. For example, as described above, the gap between the hinge housing 150 and the first housing 110 and the second housing 120 is blocked using a first dustproof structure 310 and a second dustproof structure 320, thereby blocking foreign objects through the gap between the hinge housing 150 and the first housing 110 and the second housing 120. On the other hand, during the process of placing the display 160 on the hinge housing 150, in order to allow the display 160 to be folded, the display 160 may be set to the upper surface of the hinge housing 150 in a substantially non-adhesive state. Therefore, foreign objects may be introduced through the gap between the two side edges of the central portion of the display 160 and the hinge housing 150 (or between the hinge housing 150 and the surrounding structure (e.g., the first support member 161a, the second support member 161b, and the display 160)). Such a foreign object inflow channel can be Figures 14 to 16 The dustproof structure described in the text is blocked.

[0111] Figure 14 This is a diagram illustrating an example of a dustproof structure disposed inside a hinge housing according to an embodiment of the present disclosure.

[0112] Reference Figure 14 , it is along Figure 13 The cross-sectional view taken along line E-E' shows the state in which the first-side dustproof structure 330a is disposed according to an embodiment of the present disclosure. The first-side dustproof structure 330a may be included in... Figure 6 At least one of the third dustproof structure 330 and the fourth dustproof structure 340 arranged on the two side edges of the hinge housing 150 as described herein.

[0113] The first dustproof structure 330a may include a first portion 330a_1 that at least partially faces or contacts the interior of the hinge housing 150 and at least partially contacts or faces the display 160 (or as a component including the above). Figure 11 The second portion 330a_2 is located on one side of the display 160 described herein, or at least a portion of another structure or housing of the support member or protective member. According to various embodiments of this disclosure, at least some other portions of the first portion 330a_1 may face or contact the display 160. According to various embodiments of this disclosure, at least some other portions of the second portion 330a_2 may not contact the display 160 and may be disposed in an empty space.

[0114] The first part 330a_1 may be configured to have a predetermined thickness and width, stand upright from the substrate part 330a_3 and contact the sidewall of the hinge housing 150. The first part 330a_1 may include, for example, a pad with elastic force. The second part 330a_2 may be composed of at least one polymer, the polymer comprising substances applied to the above-mentioned... Figures 5 to 11 The dustproof structure described herein uses fibers. The first portion 330a_1 and the second portion 330a_2 may be disposed on one side of the hinge housing 150 and stand upright in the y-axis direction, and the second portion 330a_2 may be configured to be bent along the -x-axis direction or the x-axis direction depending on the configuration of the display 160. The y-axis height of the first portion 330a_1 and the y-axis height of the second portion 330a_2 may be the same, or the y-axis height of the second portion 330a_2 may be lower than the y-axis height of the first portion 330a_1.

[0115] According to various embodiments of this disclosure, the adhesive member 159a may be disposed between the first dustproof structure 330a and the inner surface of the hinge housing 150. The adhesive member 159a may be disposed between the first portion 330a_1 and the hinge housing 150, and / or between the substrate portion 330a_3 on which the first portion 330a_1 and the second portion 330a_2 are mounted, and the bottom surface of the hinge housing. With the above configuration, firstly, the first portion 330a_1 can be used to block the gap between the display 160 and the hinge housing 150; secondly, the second portion 330a_2 can be used to block the gap between the display 160 and the hinge housing 150, thereby preventing foreign matter from flowing in.

[0116] According to various embodiments of this disclosure, the fiber density of each component of the first-side dustproof structure 330a may be different. For example, the fiber density of the second portion 330a_2 located near the first portion 330a_1 may be relatively high, while the fiber density of the second portion 330a_2 located away from the first portion 330a_1 may be relatively low. Therefore, foreign matter flowing in through the gap between the display 160 and the hinge housing 150 can be blocked more firmly.

[0117] Figure 15 This is a diagram illustrating another example of a dustproof structure disposed inside a hinge housing according to an embodiment of the present disclosure.

[0118] Reference Figure 15 Similar to Figure 14 As shown in the accompanying drawings, the electronic device 100 may include a display 160 (or a structure including a display 160), a hinge housing 150, a first housing 110 (or a second housing), a first hinge structure 200a (or a second hinge structure 200b), and a second-side dustproof structure 330b. The aforementioned display 160, hinge housing 150, first housing 110, and first hinge structure 200a may be respectively associated with the components shown in Figures 1 to 200. Figure 11The components described herein correspond to those described above. The second dustproof structure 330b may be at least one of the third dustproof structure 330 and the fourth dustproof structure 340 described above. According to various embodiments of this disclosure, the electronic device 100 may further include an adhesive member 159b disposed between the second dustproof structure 330b and the hinge housing 150.

[0119] The second-side dustproof structure 330b may include a structure comprising a polymer containing the same fibers. The second-side dustproof structure 330b may include: a third portion 330b_1, disposed adjacent to the display 160 but not superimposed on the display 160 in the vertical direction (e.g., the y-axis to -y-axis direction); a fourth portion 330b_2, at least partially superimposed on the display 160 in the vertical direction; and a substrate portion 330b_3. The third portion 330b_1 and the fourth portion 330b_2 may comprise polymers of substantially the same fibers. The third portion 330b_1 may be pushed by the display 160 against the sidewall of the hinge housing 150, and therefore may have a higher polymer arrangement density than the polymer arrangement density of the fourth portion 330b_2. The fourth portion 330b_2 may contact the rear surface of the display 160 (or the rear surface of a structure including the display 160), and therefore may be configured to bend along a specific direction. An adhesive layer may also be disposed between the substrate portion 330b_3 and at least a portion of the inner surface of the hinge housing 150. According to various embodiments of this disclosure, the fiber density of each component of the second-side dustproof structure 330b may be different. For example, the fiber density disposed in the third portion 330b_1 may be configured to be higher than the fiber density disposed in the fourth portion 330b_2. Alternatively, in second-side dustproof structures 330b with the same fiber density, the third portion 330b_1 may be compressed by at least a portion of the structure including the display 160, thereby increasing the fiber arrangement density toward the fourth portion 330b_2.

[0120] Figure 16 This is a diagram illustrating yet another example of a dustproof structure disposed inside a hinge housing according to an embodiment of the present disclosure.

[0121] Reference Figure 16 In addition to the third-side dustproof structure 330c, the electronic device 100 according to embodiments of this disclosure may have similar features. Figure 14 The construction. For example, similar to Figure 14 As shown in the accompanying drawings, the electronic device 100 may include a display 160 (or a structure including a display 160), a hinge housing 150, a first housing 110 (or a second housing), and a first hinge structure 200a (or a second hinge structure 200b), and may include a third-side dustproof structure 330c. The aforementioned display 160, hinge housing 150, first housing 110, and first hinge structure 200a may be respectively associated with those shown in Figures 1 to 2004. Figure 11The components described herein correspond to those in the present disclosure. According to various embodiments of this disclosure, the electronic device 100 may further include an adhesive member 159c disposed between the third-side dustproof structure 330c and the hinge housing 150.

[0122] The third-side dustproof structure 330c may include a structure comprising an aggregate of identical fibers extending (aligned in the horizontal direction) along the x-axis to -x-axis direction. The third-side dustproof structure 330c may include a substrate portion 330c_3 disposed adjacent to the hinge housing 150, and a fifth portion 330c_1 and a sixth portion 330c_2 disposed on a surface of the substrate portion 330c_3 in the -x-axis or x-axis direction. The fifth portion 330c_1 may be disposed below the display 160 to primarily enclose the space between the display 160 and the inner surface of the hinge housing 150. The sixth portion 330c_2 may be disposed along the -x-axis direction and positioned below the fifth portion 330c_1 based on the y-axis to contact at least a portion of the device elements of the electronic device 100 or the housing. The length of the fibers (or the length of the aggregate) of the fifth portion 330c_1 may be shorter than the length of the fibers of the sixth portion 330c_2. In the accompanying drawings, the thickness of the fifth portion 330c_1 may be formed to be similar to the thickness of the display 160 (or include the thickness of at least a portion of the structure comprising the display 160). The sixth portion 330c_2 may be configured to face at least a portion of the hinge structure 200a and may be configured to have a length that does not affect the hinge operation of the hinge structure 200a. According to various embodiments of the present disclosure, the fiber density of each component of the third-side dustproof structure 330c may be different. For example, the fiber density disposed in the fifth portion 330c_1 may be formed to be higher than the fiber density disposed in the sixth portion 330c_2. Alternatively, in a second-side dustproof structure 330c with the same fiber density, the fifth portion 330c_1 may be compressed by at least a portion of the structure comprising the display 160, thereby increasing the fiber arrangement density toward the sixth portion 330c_2.

[0123] exist Figures 5 to 11 The present disclosure describes dustproof structures formed in the first housing 110 and the second housing 120, respectively; however, this disclosure is not limited thereto. Furthermore, Figures 14 to 16The dustproof structure is shown partially disposed inside the hinge housing; however, according to various embodiments of the present disclosure, at least one of the first dustproof structure 310, the second dustproof structure 320, the third dustproof structure 330, and the fourth dustproof structure 340 may be disposed on at least one of the first bend 115, the second bend 125, one side edge of the hinge housing 150, and the other side edge of the hinge housing 150, as needed. Therefore, the electronic device 100 according to embodiments of the present disclosure may include only one dustproof structure (e.g., the first dustproof structure 310), or the electronic device 100 may include all of a plurality of dustproof structures. According to various embodiments of the present disclosure, the fibers of at least one of the first dustproof structure 310, the second dustproof structure 320, the third dustproof structure 330, the fourth dustproof structure 340, the first side dustproof structure 330a, the second side dustproof structure 330b, and the third side dustproof structure 330c may be fluorinated. Fluorine coating prevents moisture, water, or liquid from being introduced into the electronic device 100 from the outside of the hinge housing 150.

[0124] Figure 17 This is a diagram illustrating an example of an electronic device in a free-stopped state according to an embodiment of the present disclosure.

[0125] Reference Figure 17 An electronic device 100 employing at least one of the aforementioned first dustproof structure 310, second dustproof structure 320, third dustproof structure 330, fourth dustproof structure 340, first-side dustproof structure 330a, second-side dustproof structure 330b, and third-side dustproof structure 330c may have a free-stop function. For example, if the first housing 110 and the second housing 120 are arranged at a specific angle, such as in state 1701 or state 1703, at least a portion of at least one dustproof structure contacts the first housing 110 and the second housing 120, and therefore the first housing 110 and the second housing 120 may maintain a specific angular state based on friction with at least a portion of at least one dustproof structure. In the illustrated figures, state 1701 or state 1703 is shown as being at 120 degrees or 90 degrees; this disclosure is not limited thereto. For example, since at least a portion of at least one dustproof structure remains in continuous contact with the first housing 110 and the second housing 120, the first housing 110 and the second housing 120 can be installed at any angle from 0 degrees to 180 degrees based on friction with at least a portion of at least one dustproof structure (free stop function).

[0133] According to various embodiments of this disclosure, the second portion may have a larger area than the first portion.

[0134] According to various embodiments of this disclosure, the density of fibers disposed on the first portion may be higher than the density of fibers disposed on the second portion.

[0135] According to various embodiments of the present disclosure, at least one fiber structure may include: a substrate portion 311 including a plurality of holes; and a fiber bundle 312 disposed in the plurality of holes of the substrate portion.

[0136] According to various embodiments of this disclosure, multiple holes can be arranged in a zigzag pattern.

[0138] According to various embodiments of the present disclosure, at least one fiber structure may include a second dustproof structure 320 disposed along one side edge of the second bend.

[0139] According to various embodiments of the present disclosure, the electronic device may further include an adhesive member 159a disposed between the second dustproof structure and the second curved portion of the second housing.

[0140] According to various embodiments of the present disclosure, at least one fiber structure may further include a third dustproof structure 330 disposed on one side edge of the hinge housing.
