According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, a memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connection terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a user identification module (SIM) 196, or an antenna module 197. In an embodiment, at least one of the above components (e.g., the connection terminal 178) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101.

[0043] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)) and supporting direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with the external electronic device 104 via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a local area network LAN or a wide area network (WAN))). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multiple components (e.g., multiple chips) separated from each other. The wireless communication module 192 may identify or authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0044] The wireless communication module 192 can support 5G networks after 4G networks and next-generation communication technologies (e.g., new radio (NR) access technology). NR access technology can support enhanced mobile broadband (eMBB), massive machine type communication (mMTC), or ultra-reliable low-latency communication (URLLC). The wireless communication module 192 can support high-frequency bands (e.g., millimeter wave bands) to achieve, for example, high data transmission rates. The wireless communication module 192 can support various technologies for ensuring performance on high-frequency bands, such as, for example, beamforming, massive multiple-input multiple-output (massive MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. The wireless communication module 192 can support various requirements specified in the electronic device 101, an external electronic device (e.g., electronic device 104), or a network system (e.g., a second network 199). According to an embodiment, the wireless communication module 192 may support a peak data rate for implementing eMBB (e.g., 20 Gbps or greater), loss coverage for implementing mMTC (e.g., 164 dB or less), or U-plane delay for implementing URLLC (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip).

[0045] The antenna module 197 may send a signal or power to the outside (e.g., an external electronic device) or receive a signal or power from the outside (e.g., an external electronic device). According to an embodiment, the antenna module 197 may include an antenna including a radiator formed by a conductor or a conductive pattern formed on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, the antenna module 197 may include a plurality of antennas (e.g., an antenna array). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as the first network 198 or the second network 199) may be selected from the plurality of antennas by, for example, the communication module 190. A signal or power may then be sent or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, additional components (e.g., a radio frequency integrated circuit (RFIC)) other than the radiator may be further formed as part of the antenna module 197.

[0046] According to an embodiment, the antenna module 197 may form a millimeter wave antenna module. According to an embodiment, the millimeter wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and a plurality of antennas (e.g., array antennas), wherein the RFIC is disposed on a first surface (e.g., bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a specified high frequency band (e.g., millimeter wave band), and the plurality of antennas are disposed on a second surface (e.g., top surface or side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the specified high frequency band.

[0047] At least some of the above components may be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.

[0048] According to an embodiment, a command or data may be sent or received between the electronic device 101 and the external electronic device 104 via the server 108 connected to the second network 199. Each of the electronic device 102 or the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type from the electronic device 101. According to an embodiment, all or some operations to be executed in the electronic device 101 may be executed in one or more of the external electronic device 102, the external electronic device 104, or the server 108. For example, if the electronic device 101 should automatically execute a function or service or should execute a function or service in response to a request from a user or another device, the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service instead of executing the function or service, or the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service in addition to executing the function or service. The one or more external electronic devices receiving the request may execute at least part of the requested function or service, or execute another function or another service related to the request, and transmit the result of the execution to the electronic device 101. The electronic device 101 may provide the result as at least a partial reply to the request in the case of further processing the result or in the case of not further processing the result. To this end, cloud computing technology, distributed computing technology, mobile edge computing (MEC) technology or client-server computing technology, for example, may be used. The electronic device 101 may use, for example, distributed computing or mobile edge computing to provide ultra-low latency services. In an embodiment, the external electronic device 104 may include an Internet of Things (IoT) device. The server 108 may be an intelligent server using machine learning and / or neural networks.

The electronic device 101 may be applied to intelligent services (e.g., smart homes, smart cities, smart cars or health care) based on 5G communication technology or IoT-related technologies.

[0049] In the following detailed description, the length direction, width direction and / or thickness direction of the electronic device may be mentioned, and may, for example, refer to the "Y-axis direction", "X-axis direction" and / or "Z-axis direction", respectively. In an embodiment, "negative / positive (- / +)" may be referred to together with the Cartesian coordinate system of the direction relative to the orientation of the component shown in the accompanying drawings. For example, the front surface of the electronic device or the housing may refer to, for example, the "surface facing the +Z direction", and the rear surface may refer to, for example, the "surface facing the -Z direction". In an embodiment, the side surface of the electronic device or the housing may include an area facing the +X direction, an area facing the +Y direction, an area facing the -X direction and / or an area facing the -Y direction. In an embodiment, the "X-axis direction" may include both the "-X direction" and the "+X direction". It should be noted that for the sake of simplicity of description, directions are shown relative to the Cartesian coordinate system shown in the accompanying drawings, and the description of these directions or components does not limit the embodiments of the present disclosure. For example, the direction facing the front surface or the rear surface may change according to the unfolded state or the folded state of the electronic device, and the above directions may be interpreted as different directions according to the user's grip.

[0050] Figure 2 is a diagram illustrating an unfolded state of an electronic device according to an embodiment of the present disclosure. Figure 3 is a diagram illustrating a folded state of an electronic device according to an embodiment of the present disclosure. Figure 2 and Figure 3 The configuration of the electronic device 200 may be Figure 1 The configurations of the electronic devices 101 are completely or partially the same.

[0051] Figure 2 The unfolded state of the electronic device may be defined as an opened flexible display, Figure 3 The folded state of the electronic device may be defined as a closed flexible display. According to an embodiment, the unfolded state may be defined as at least one of an open state, an extended state, an extended state, an unbent state, or a first state. The folded state may be defined as at least one of a closed state, a bent state, or a second state. Figure 2 and Figure 3 The electronic device 200 may include a component for accommodating the electronic device 200 (eg Figure 4 The housing 202 includes a battery 250 and / or a circuit board 260 (a battery 250 and / or a circuit board 260) and a flexible display or a foldable display 230 (hereinafter referred to as the display 230) connected to the housing 202. According to an embodiment, the housing 202 may be referred to as a foldable housing.

[0052] According to an embodiment, the housing 202 may include a first housing 210 and a second housing 220 configured to relatively rotate about the first housing 210 .

[0053] According to an embodiment, the first housing 210 and / or the second housing 220 may form a part of the exterior of the electronic device 200. According to an embodiment, the surface of the display 230 that is visually exposed (e.g., visible) may be the front surface of the electronic device 200 and / or the housing 202 (e.g., the first front surface 210a and the second front surface 220a). As used herein, when referring to a display, the terms "visually exposed", "exposed", "visible", etc. may be used interchangeably and include a display having a cover glass, a cover layer, a protective layer, etc. covering the display. The surface opposite to the front surface may be the rear surface of the electronic device 200 (e.g., the first rear surface 210b and the second rear surface 220b). The surface surrounding at least a portion of the space between the front surface and the rear surface may be the side surface of the electronic device 200 (e.g., the first side surface 210c and the second side surface 220c).

[0054] According to an embodiment, the second housing 220 may be connected to be rotatable around the first housing 210. For example, the first housing 210 and the second housing 220 may be connected by a hinge structure (eg, Figure 4 The electronic device 200 can be turned into a folded state (for example, Figure 2 ) and expanded states (e.g. Figure 3 ). In the folded state of the electronic device 200, the first front surface 210a may face the second front surface 220a, and in the unfolded state, the direction facing the first front surface 210a may be the same as the direction facing the second front surface 220a. For example, in the unfolded state, the first front surface 210a may be located on substantially the same plane as the second front surface 220a. According to an embodiment, the first housing 210 may use an interlocking structure (e.g. Figure 6 The interlocking structure 330 of the second housing 202 receives the rotational force of the second housing 202 and rotates in coordination with the second housing 220. In contrast, the second housing 220 can use an interlocking structure (e.g. Figure 6 The interlocking structure 330 receives the rotational force of the first shell 210 and rotates in coordination with the first shell 210.

[0055] According to an embodiment, the first housing 210 and the second housing 220 are disposed on both sides of the folding axis A and are overall symmetrical in shape relative to the folding axis A. The angle between the first housing 210 and the second housing 220 may be changed depending on whether the electronic device 200 is in an unfolded state, a folded state, or an intermediate state between the unfolded state and the folded state.

[0056] According to an embodiment, the electronic device 200 may include a hinge cover 240. At least a portion of the hinge cover 240 may be disposed between the first housing 210 and the second housing 220. According to an embodiment, the hinge cover 240 may be hidden or exposed to the outside by a portion of the first housing 210 and the second housing 220, depending on the state of the electronic device 200. According to an embodiment, the hinge cover 240 may protect the hinge structure (e.g., Figure 4 The hinge structure 280 of the electronic device 200 is protected from external impacts. According to an embodiment, the hinge cover 240 may be referred to as a hinge housing.

[0057] According to the embodiment, Figure 2 As shown, in the unfolded state of the electronic device 200, the hinge cover 240 can be hidden by the first shell 210 and the second shell 220 and thus not exposed. As another example, Figure 3 As shown, in the folded state (e.g., fully folded state) of the electronic device 200, the hinge cover 240 may be exposed to the outside between the first housing 210 and the second housing 220. As another example, in the intermediate state where the first housing 210 and the second housing 220 are folded at a certain angle, the hinge cover 240 may be partially exposed to the outside between the first housing 210 and the second housing 220. However, in this case, the exposed area may be smaller than the exposed area in the fully folded state. According to an embodiment, the hinge cover 240 may include a curved surface.

[0058] According to the embodiment, Figure 3 As shown, when the electronic device 200 is in a folded state (eg, a fully folded state), the hinge structure (eg, Figure 4 The edges of the adjacent first shell 210 and the edges of the second shell 220 may contact each other without a gap.

[0059] According to an embodiment, when the electronic device 200 is in a folded state (e.g., in a fully folded state), the edge of the first housing 210 and the edge of the second housing 220 adjacent to the hinge structure 280 may be spaced apart from each other. For example, when the electronic device 200 is in a folded state, a gap may be formed between the edge of the first housing 210 and the edge of the second housing 220 adjacent to the hinge structure 280. The distance between the first housing 210 and the second housing 220 within the gap may decrease as the distance from the hinge structure increases. According to an embodiment, when the electronic device 200 is in a folded state, since a gap is formed between the first housing 210 and the second housing 220 to correspond to the folding area 233 of the display 230, stress of the display 230 may be reduced or prevented.

[0060] According to an embodiment, the display 230 may visually provide information to the outside of the electronic device 200 (e.g., a user).

For example, the interlocking structure 330 may rotate the second housing 220 by an angle substantially the same as the angle at which the first housing 210 is rotated.

[0086] In an embodiment, the interlocking structure 330 may include gear shafts 331 and 332 and a plurality of gears 333 a , 333 b , and 334 .

According to an embodiment, a first gear 333a may be included on an outer circumferential surface of the first gear shaft 331, and a second gear 333b may be included on an outer circumferential surface of the second gear shaft 332. According to an embodiment, the first gear 333a of the first gear shaft 331 may be engaged with the second gear 333b of the second gear shaft 332 to interlock the first housing 210 and the second housing 220. For example, a force transmitted from the first rotating member 311 coupled to the first housing 210 may be transmitted to the first gear shaft 331 through the first arm member 321. The second gear shaft 332 meshed with the first gear shaft 331 may receive the force and rotate in a direction different from the rotation direction of the first gear shaft 331. The force transmitted to the second gear shaft 332 may be transmitted to the second arm member 322 and / or the second housing 220. According to an embodiment, ends of the gear shafts 331 and 332 may be inserted into the rotating bracket 350 .

[0088] According to an embodiment, the hinge structure 300 (e.g., the interlocking structure 330) may include a gear shaft supporting member 335. According to an embodiment, the gear shaft supporting member 335 may include at least one through hole for accommodating the gear shafts 331 and 332 and / or the idler gear 334. For example, the gear shaft supporting member 335 may prevent or reduce the gear shafts 331 and 332 and / or the idler gear 334 from disengaging.

[0089] In an embodiment, the fixing structure 320 may include a first arm member 321 connected to the first rotating member 311 and a second arm member 322 connected to the second rotating member 312. For example, the arm members 321 and 322 together with the gear shafts 331 and 332 may rotate around the interlocking axes Ax3 and Ax4. According to an embodiment, the first arm member 321 together with the first gear shaft 331 may rotate around the first interlocking axis Ax3. According to an embodiment, the second arm member 322 together with the second gear shaft 332 may rotate around the second interlocking axis Ax4.

For example, the first arm member 321 may include a first through hole 325a for accommodating one end of the first gear shaft 331. For example, the second arm member 322 may include a second through hole 325b for accommodating one end of the second gear shaft 332.

For example, the first rotation axis Ax1, the second rotation axis Ax2, the first interlocking axis Ax3, and the second interlocking axis Ax4 may be substantially parallel to each other.

[0090] According to an embodiment, the fixing structure 320 may receive a force from the rotating members 311 and 312 or transmit a force to the rotating members 311 and 312 through at least one pin member 323a and 323b. For example, the pin members 323a and 323b may protrude from the surface of the arm members 321 and 322 facing the rotating members 311 and 312. For example, the pin members 323a and 323b may be formed integrally with the arm members 321 and 322, or as separate members, may be coupled to the arm members 321 and 322. For example, the pin members 323a and 323b may be slidably connected to the rotating members 311 and 312. According to an embodiment, the pin members 323a and 323b may be inserted in the through grooves 313a and 313b formed in the rotating members 311 and 312. Figure 7 For example, the direction of arrow ① may be substantially parallel to the direction of the electronic device (eg Figures 2 to 4The electronic device 200) or the length direction (Y-axis direction) of the hinge structure 300. According to an embodiment, the first arm member 321 may include a first pin member 323a, and the first pin member 323a is slidably connected to a first through-slot 313a formed in the first rotating member 311. According to an embodiment, the second arm member 322 may include a second pin member 323b, and the second pin member 323b is slidably connected to a second through-slot 313b formed in the second rotating member 312. For example, when the first pin member 323a and / or the second pin member 323b slides in the through-slot 313a or 313b and / or the braking groove 401 or 402 (for example, refer to Figure 9a and Figure 9b ), the difference between the rotation axis of the rotating member 311 or 312 and the interlocking axis of the interlocking structure 330 and / or the fixed structure 320 can be corrected. According to an embodiment, the pin members 323a and 323b can slide in the direction of arrow ① in the braking grooves 401 and 402 of the braking member 400 provided in the through grooves 313a and 313b of the rotating members 311 and 312. For example, the extending direction of the through groove 313a or 313b and the braking groove 401 or 402 can be consistent with the hinge structure 300 or the electronic device (for example Figures 2 to 4 For example, the sliding of the pin members 323a and 323b in the through grooves 313a and 313b can be interpreted as the sliding of the pin members 323a and 323b in the braking grooves 401 and 402.

[0091] The configuration of the hinge structure 300 in the present disclosure is optional. For example, at least one of the rotating structure 310, the interlocking structure 330, and the fixing structure 320 of the hinge structure 300 may be changed or omitted. The brake member 400 in the present disclosure is not separated from the embodiment of the hinge structure 300 of the present disclosure. For example, a hinge structure (e.g., Figure 4 280 and / or Figure 5 and 6 300) may include various types of interlocking structures (e.g. Figures 5 to 7 The interlocking structure 330 of the hinge structure of the application brake member 400. In an embodiment, the interlocking structure of the hinge structure of the application brake member 400 may include various types of gears (e.g., spur gears, helical gears, or worm gears). In an embodiment, the interlocking structure of the hinge structure of the application brake member 400 may not include gears. For example, the interlocking structure may include a spiral structure. For example, the interlocking structure may be connected in the width direction (X-axis direction) of the hinge structure 300 relative to the rotating members 311 and 312.

[0092] In an embodiment, the hinge structure 300 may include at least one braking member 400, which provides a stopping force or a fastening force for the first housing 210 and / or the second housing 220. For example, the braking member 400 may also be interpreted as a member separate from the hinge structure 300. For example, referring to Figure 8 The braking member 400 may be a part (eg, through grooves 313a and 313b) of the rotating members 311 and 312. For example, the braking member 400 may be installed to be at least partially accommodated in the through grooves 313a and 313b formed in the rotating members 311 and 312.

[0093] According to an embodiment, the braking member 400 may include an elastic material (elastomer). The braking member 400 may provide a force in a specific direction in response to the elastic force generated by the elastic material, thereby Figure 9a , Figure 9b The left and right movement of the pin members 323a and 323b in the embodiment of the present invention (401 and 402) can provide the user with a sense of control (eg, a sense of being stuck or stopped during movement).

[0094] According to an embodiment, when the foldable electronic device is operated from the unfolded state to the folded state or from the folded state to the unfolded state, the brake member 400 may be formed to provide a free stop structure at a specific point. The brake member 400 may guide the operation of the electronic device from the unfolded state to the folded state or the operation of the electronic device from the folded state to the unfolded state.

[0095] According to embodiments, the braking member 400 may be referred to as a braking portion, an elastic member, an elastic body, a variable portion, or a deformable portion.

[0096] Reference Figure 7 and Figure 8 In an embodiment, the brake member 400 may include a first brake member 400a disposed in the first housing 210 and a second brake member 400b disposed in the second housing 220. For example, the first brake member 400a may be at least partially accommodated in a first through groove 313a formed in the first rotating member 311. For example, the second brake member 400b may be at least partially accommodated in a second through groove 313b formed in the second rotating member 312.

[0097] In an embodiment, the brake member 400 may include brake grooves 401 and 402 connected to the pin members 323a and 323b of the arm members 321 and 322. For example, the brake grooves 401 and 402 may be provided on the hinge structure 300 or the electronic device (eg Figures 2 to 4The electronic device 200 of the embodiment of the present invention is a hole or groove that penetrates in the width direction (X-axis direction) of the hinge structure 300 and extends in the length direction (Y-axis direction). For example, the braking grooves 401 and 402 may have a predetermined thickness in the width direction (X-axis direction) of the hinge structure 300. For example, at least a portion of the first pin member 323a may be accommodated in the first braking groove 401 formed in the first braking member 400a. At least a portion of the second pin member 323b may be accommodated in the second braking groove 402 formed in the second braking member 400b. According to an embodiment, the braking grooves 401 and 402 may be formed to surround at least a portion of the accommodated pin members 323a and 323b. In an embodiment, the cross-section of the pin members 323a and 323b in the width direction (Y-axis direction) may be circular. For example, the braking grooves 401 and 402 may include a curved surface that at least partially surrounds the outer peripheral surface of the pin members 323a and 323b. However, the shape of the cross section of the pin members 323a and 323b in the width direction (Y-axis direction) is not limited to a circular shape. For example, the cross section of the pin members 323a and 323b in the width direction may have various shapes, such as an ellipse or a polygon (rectangle or pentagon). For example, the braking member 400 or the braking grooves 401 and 402 may be formed in various shapes to at least partially surround the pin members 323a and 323b.

[0098] According to an embodiment, the brake member 400 can provide a force (fastening force) to the interlocking structure 330 and / or the rotating structure 310 to position the first housing 210 and the second housing 220 at a certain angle. For example, the brake member 400 can provide a force (elastic force) to the pin members 323a and 323b of the interlocking structure 330 (for example, Fig.11b), which acts in the width direction of the pin members 323a and 323b. For example, when the pin members 323a and 323b have a circular cross-section in the width direction, the force (elastic force) provided by the brake member 400 can act in a direction perpendicular to the outer peripheral surface of the pin members 323a and 323b. For example, the pin members 323a and 323b of the arm members 321 and 322 can transfer the elastic force of the brake member 400 to the interlocking structure 330 and / or the rotating structure 310. For example, the elastic force of the brake member 400 can be used as a force to prevent or reduce the movement and / or rotation of the first shell 210 and / or the second shell 220. For example, the brake member 400 can provide an elastic force of a predetermined value or greater. For example, when the user applies an external force of a specified value or greater, the first shell 210 and / or the second shell 220 can rotate. For example, when no external force is applied or an external force less than a specified value is applied, the first housing 210 and / or the second housing 220 can be kept in a stopped state due to the elastic force of the brake member 400. According to an embodiment, for example, the brake member 400 may include various materials that provide a specified value or a greater elastic force. For example, the brake member 400 may have a yield strength that resists an external force within a numerical range that is usually provided by a user for moving and / or rotating the first housing 210 and / or the second housing 220. For example, the yield strength of the brake member 400 may be about 1000Mpa or greater. In an embodiment, the brake member 400 may include a metal, such as nickel or chromium. For example, the brake member 400 may include austenitic stainless steel. As another example, the brake member 400 may include a spring metal, such as 304 stainless steel or 301 stainless steel. However, the above-mentioned yield strength and material of the brake member 400 are only examples and are not limited thereto.

The first hole area 410a may be a space having a shape corresponding to a portion of the first pin member 323a accommodated in the first brake groove 401. In an embodiment, when the first pin member 323a is accommodated in the first hole area 410a, the first brake member 400a is not deformed by the first pin member 323a. According to an embodiment, the first hole area 410a may be composed of Figure 9a The dotted line indicates the area.

In an embodiment, the first brake groove 401 may include a 1-1 connection area 421, a 1-2 connection area 422, and a 1-3 connection area 423 that are spaced apart from each other. For example, the 1-1 connection area 421 may connect the 1-1 hole area 411 and the 1-2 hole area 412. The 1-2 connection area 422 may connect the 1-2 hole area 412 and the 1-3 hole area 413. The 1-3 connection area 423 may connect the 1-3 hole area 413 and the 1-4 hole area 414.

For example, the first connection area 420a may be a space for accommodating the first pin member 323a. In an embodiment, if the first pin member 323a is accommodated in the first connection area 420a, the first brake member 400a may be deformed by the first pin member 323a. For example, the first connection area 420a may be an inner space of the first brake groove 401 surrounded by the first brake member 400a and two hole areas 410a contacting opposite sides of the first connection area 420a. However, the number, arrangement and / or shape of the hole areas 410a and the connection areas 420a of the first brake groove 401 are not limited thereto.

For example, the second hole area 410b may be a space for accommodating the second pin member 323b. The second hole area 410b may be a space having a shape corresponding to a portion of the second pin member 323b accommodated in the second brake groove 402. In an embodiment, when the second pin member 323b is accommodated in the second hole area 410b, the second brake member 400b is not deformed by the second pin member 323b. According to an embodiment, the second hole area 410b may be composed of Figure 9b For example, the second hole region 410b may represent an inner space of the cylindrical second braking groove 402 corresponding to the second pin member 323b.

[0106] According to an embodiment, the second braking member 400b (e.g., the second braking groove 402) may include at least one second connection area 420b that forms a narrower path between adjacent hole areas 410b than the second hole area 410b. In an embodiment, the second braking groove 402 may include a 2-1st connection area 424, a 2-2nd connection area 425, and a 2-3rd connection area 426 that are spaced apart from each other. For example, the 2-1st connection area 424 may connect the 2-1st hole area 415 and the 2-2nd hole area 416. The 2-2nd connection area 425 may connect the 2-2nd hole area 416 and the 2-3rd hole area 417. The 2-3rd connection area 426 may connect the 2-3rd hole area 417 and the 2-4th hole area 418. For example, the second connection area 420b may be a space for accommodating the second pin member 323b. In an embodiment, if the second pin member 323b is accommodated in the second connection area 420b, the second braking member 400b may be deformed by the second pin member 323b. For example, it may be the inner space of the second braking groove 402 surrounded by the second braking member 400b and the two hole areas 410b contacting the opposite sides thereof. However, the number, arrangement and / or shape of the hole areas 410b and the connection area 420b of the second braking groove 402 are not limited thereto.

[0107] According to an embodiment, “a state in which the pin members 323a and 323b are seated in the hole regions 410a and 410b” may mean a state in which the pin members 323a and 323b are positioned in the hole regions 410a and 410b without deforming the brake member 400. For example, Fig.11b The first pin member 323a may be in a state of being disposed in the 1-1 hole region 411 of the first brake groove 401. In a state where the pin members 323a and 323b are disposed in the hole regions 410a and 410b, the pin members 323a and 323b may not be positioned in the connection regions 420a and 420b. According to an embodiment, "a state where the pin members 323a and 323b are positioned in the connection regions 420a and 420b" may mean a state where at least a portion of the pin members 323a and 323b remain in the connection regions 420a and 420b. For example, Figure 12b The first pin member 323a shown may be in a state of being positioned in the 1-1 connection region 421 of the first braking groove 401. According to an embodiment, in a state in which the pin members 323a and 323b are positioned in the connection regions 420a and 420b, at least a portion of the connection regions 420a and 420b may be deformed by the pin members 323a and 323b. For example, in a state in which the pin members 323a and 323b are positioned in the connection regions 420a and 420b, at least a portion of the pin members 323a and 323b may also be positioned in the connection regions 420a and 420b. According to an embodiment, based on the first housing 210 (e.g. Figures 2 to 4 The first housing 210) and / or the second housing 220 (eg Figures 2 to 4 By rotating the second housing 220), the pin members 323a and 323b can be switched between a state of being disposed in the hole regions 410a and 410b and a state of being positioned in the connection regions 420a and 420b.

[0108] Reference Fig.10 In an embodiment, the state in which the pin members 323a and 323b are arranged in any one of the hole regions 410a and 410b may correspond to a state in which the angle (opening angle) between the first housing 210 and the second housing 220 is a specific angle. According to an embodiment, the fastening force of the first housing 210 and / or the second housing 220 may be enhanced at a specific opening angle corresponding to each of the first hole regions 410a and 410b compared to other angles. For example, the number of specific angles may be substantially the same as the number of hole regions 410a or 410b.

[0109] Fig.10 The hinge structure 300 is shown in the states C1 to C4 in which the hinge structure 300 forms a specific opening angle. Fig.10 In the state C1 of the hinge structure 300 shown, the angle (opening angle) between the first shell 210 and the second shell 220 may be the first specified angle x1. According to an embodiment, in the state C1 of the hinge structure 300, the first pin member 323a may be disposed in the 1-1 hole area 411, and the second pin member 323b may be disposed in the 2-1 hole area 415. According to an embodiment, in Fig.10 In the state C2 of the hinge structure 300 shown, the opening angle may be a second specified angle x2. In the embodiment, in the state C1 of the hinge structure 300, the electronic device (eg Figures 2 to 4 The electronic device 200) may be in an unfolded state, and the first specified angle may be about 180 degrees. According to an embodiment, in state C2 of the hinge structure 300, the first pin member 323a may be disposed in the 1-2 hole region 412, and the second pin member 323b may be disposed in the 2-2 hole region 416. For example, the second specified angle x2 may be smaller than the first specified angle x1. In an embodiment, the second specified angle may be about 12 ... Fig.10 In the state C3 of the hinge structure 300 shown, the opening angle may be the third specified angle x3. According to an embodiment, in the state C3 of the hinge structure 300, the first pin member 323a may be disposed in the 1-3 hole region 413, and the second pin member 323b may be disposed in the 2-3 hole region 417. For example, the third specified angle x3 may be smaller than the second specified angle x2. In an embodiment, the second specified angle may be approximately 120 degrees. In an embodiment, the third specified angle may be approximately 60 degrees. According to an embodiment, in Fig.10 In the state C4 of the hinge structure 300 shown, the opening angle may be the fourth specified angle x4. According to an embodiment, in the state C4 of the hinge structure 300, the first pin member 323a may be disposed in the 1-4 hole region 414, and the second pin member 323b may be disposed in the 2-4 hole region 418. For example, the fourth specified angle x4 may be smaller than the third specified angle x3. In an embodiment, in the state C4 of the hinge structure 300, the electronic device (e.g. Figures 2 to 4 The electronic device 200) may be in a closed state, and the fourth specified angle may be approximately 0 degrees.

[0110] In an embodiment, if the interval of the hole areas 410a and 410b is changed, the opening angle at which the fastening force of the first shell 210 and / or the second shell 220 is enhanced may vary. For example, the interval of the hole areas 410a and 410b may be the distance between the centers of the adjacent hole areas 410a and 410b. Figures 9a to 9d In an embodiment, the interval between the 1-1 hole area 411 or 415 and the 1-2 hole area 412 or 416 of the braking groove 401 or 402 may be L1. For example, the interval between the 1-2 hole area 412 or 416 and the 1-3 hole area 413 or 417 of the braking groove 401 or 402 may be L2. For example, the interval between the 1-3 hole area 413 or 417 and the 4th hole area 413 or 418 of the braking groove 401 or 402 may be L3. According to an embodiment, L1, L2 and L3 may be substantially the same. For example, when the first specified angle x1 is about 180 degrees, the second specified angle x2 is about 120 degrees, the third specified angle x3 is about 60 degrees, and the fourth specified angle x4 is 0 degrees, L1, L2 and L3 may be substantially the same. However, the specified angles between the first shell 210 and the second shell 220 are not limited to those described above. For example, the specified angle may be set or changed in consideration of the opening angle that is more frequently used by the user in practice. For example, the specified angles x1, x2, x3, and x4 may be changed by adjusting the intervals (eg, L1, L2, or L3) of the hole regions 410a and 410b.

[0111] Reference Fig.11a , Fig.11b , Fig.12a and Figure 12b In an embodiment, the pin members 323a and 323b may slide along the braking grooves 401 and 402 by external force or rotation of the first housing 210 and / or the second housing 220. For example, in Fig.11a In the unfolded state of the electronic device 200 shown in FIG. 1 , the first pin member 323 a can be placed in the 1-1 hole region 411, as shown in FIG. Fig.11bSimilarly, the second pin member 323b may be disposed in, for example, the 2-1st hole region 415. For example, if the first housing 210 and / or the second housing 220 of the electronic device 200 in the unfolded state rotates, the pin members 323a and 323b may be switched from being disposed in the first hole regions 411 and 415 to being positioned in the first connection regions 421 and 424.

[0112] In an embodiment, the brake member 400 may provide a force (elastic force) of a first specified value or greater to the pin members 323a and 323b. According to an embodiment, when the external force rotating the first shell 210 and / or the second shell 220 is greater than the first specified value, the pin members 323a and 323b may switch from being disposed in the hole areas 410a and 410b to being positioned in the connection areas 420a and 420b. According to an embodiment, the magnitude of the elastic force provided by the brake member 400 to the pin members 323a and 323b in the state of being positioned in the connection areas 420a and 420b may be greater than the first specified value. For example, in the state of being positioned in the connection areas 420a and 420b, the pin members 323a and 323b may elastically deform at least a portion of the connection areas 420a and 420b. For example, the pin members 323a and 323b may be in a direction perpendicular to the surface contacting the connection areas 420a and 420b (e.g., by Figure 12b Pressurize in the direction indicated by the arrow. Figure 12b, the first pin member 323a can pressurize a portion of the 1-1 connection area 421 to elastically deform it in a state spanning the 1-1 connection area 421. For example, the height of the deformed portion of the connection areas 420a and 420b can be substantially the same as the width d1 of the pin members 323a and 323b. According to an embodiment, due to an external force greater than the first specified value, the pin members 323a and 323b can move in the extension direction of the brake groove (e.g., the Y-axis direction) in a state positioned in the connection areas 420a and 420b. For example, the pin members 323a and 323b can be switched from a state spanning the connection areas 420a and 420b to a state disposed in the hole areas 410a and 410b. The portions of the connection areas 420a and 420b that have been deformed due to the pin members 323a and 323b can be restored to their original shapes. For example, since the external force for rotating the first housing 210 and / or the second housing 220 is less than the first specified value, the pin members 323a and 323b can be switched from the state of being positioned in the connection areas 420a and 420b to the state of being arranged in the hole areas 410a and 410b. According to an embodiment, when the pin members 323a and 323b slide along the guide groove, the external force required to switch from the state of being arranged in the hole areas 410a and 410b to the state of crossing the connection areas 420a and 420b can be the largest. Therefore, when the pin members 323a and 323b are in the state of being arranged in the hole areas 410a and 410b, the fastening force of the opening angle or the stop state of the first housing 210 and / or the second housing 220 can be maximized.

[0113] Reference Figure 9b and Figure 9d, the brake members 400a and 400b (e.g., the brake grooves 401 and 402) may include a plurality of connection areas 420a and 420b, and the minimum height d3 of at least some of the connection areas 420a and 420b may be different. For example, if the minimum height (e.g., d31) of a specific first connection area (e.g., the 1-1 connection area 421 and the 2-3 connection area 426) is reduced compared to the minimum height (e.g., d32 and d33) of another connection area, the minimum force required to elastically deform the first connection area 420a or 420b by the pin member 323a or 323b may be increased. For example, the magnitude of the external force required to switch from a state where the pin member 323a or 323b is disposed in at least one first hole area 410a or 410b contacting the specific first connection area 420a or 420b to a state where the pin member 323a or 323b is positioned in the specific first connection area 420a or 420b may be increased. For example, the magnitude of the elastic force provided by the brake member 400 to the pin member 323a or 323b in a state where the pin member 323a or 323b is positioned in the specific first connection area 420a or 420b can be increased. Therefore, in a state where the pin member 323a or 323b is disposed in the first hole area 410a or 410b contacting the specific first connection area 420a or 420b, the fastening force of the first housing 210 and / or the second housing 220 can be further enhanced. According to an embodiment, the state where the pin member 323a or 323b is disposed in the 1-1 hole area 411 or 415 can correspond to an opening angle of about 180 degrees (for example, Fig.10 In this case, if the minimum height d3 of the 1-1 connection area 421 of the first braking groove 401 is reduced, the minimum force required to switch from the state where the first pin member 323a is seated in the 1-1 hole area 411 of the first braking groove 401 to the state where it is positioned in the 1-1 connection area 421 can be increased. Similarly, if the minimum height d3 of the 2-1 connection area 424 of the second braking groove 402 is reduced, the minimum force required to switch from the state where the second pin member 323b is seated in the 2-1 hole area 415 of the second braking groove 402 to the state where it is positioned in the 2-1 connection area 424 can be increased. Therefore, the fastening force of the first shell 210 and / or the second shell 220 for maintaining the state where the opening angle is approximately 180 degrees (the unfolded state of the electronic device 200) can be enhanced.

[0114] In the electronic device 200, the first brake member 400a is disposed in the first through groove 313a of the first rotating member 311, and according to the state change of the electronic device 200 (e.g., from the unfolded state to the folded state and / or from the folded state to the unfolded state), the first pin member 323a may change the shape of the first brake member 400 while sliding in the first brake member 400. When the first pin member 323a slides repeatedly, as the shape of the first brake member 400 continuously changes in the first through groove 313a, the first brake member 400 may be separated from the first through groove 313a. Therefore, the electronic device may require a structure for preventing (e.g., reducing or limiting) the separation of the first brake member 400.

[0115] Reference Fig.12c , the electronic device 200 may include a structure for preventing (e.g., reducing or limiting) the first brake member 400a disposed in the first through-groove 313a of the first rotating member 311 from being separated from the outside of the first through-groove 313a. The first rotating member 311 may include at least one anti-separation member 311a on one side of the first through-groove 313a. The anti-separation member 311a is used to limit or reduce the movement of the first brake member 400a in the longitudinal direction (e.g., the X-axis direction) of the hinge structure 300. The anti-separation member 311a has a shape extending from the first rotating member 311 through the first through-groove 313a in a direction perpendicular to the X-axis direction, so that at least a portion thereof overlaps with the first brake member 400a. According to an embodiment, the anti-separation member 311a may be formed in plurality to limit the first brake member 400a from being separated from the first through-grooves 313a and 313b. For example, the anti-separation member 311a is formed by a plurality of pieces extending in the +Y axis direction and the -Y axis direction of the first rotating member 311, and at least a portion of each piece can be arranged to overlap with both ends of the first braking member 400a. As another example, the anti-separation member 311a is formed by a plurality of pieces extending in the +X axis direction and the -X axis direction of the first rotating member 311, and at least a portion of each piece can be arranged to overlap with both ends of the first braking member 400a. The anti-separation member 311a can be manufactured in a stepped shape. However, the number and arrangement of the anti-separation members 311a can be modified in various ways to limit the movement of the first braking member 400a without interfering with the sliding movement of the first pin member 323a.

[0116] According to an embodiment, the electronic device 200 may provide a structure for preventing the first brake member 400a provided in the first through groove 313ab of the first rotating member 311 from being disengaged from the outside of the first through groove 313a. The adhesive member may be provided between a portion of the outer surface of the first brake member 400a and the inner surface of the first rotating member 311 forming the first through groove 313a. The position where the adhesive member is provided may be limited to an area where the first brake member 400a is not variable. For example, the adhesive member may be attached to the outer surface of the first brake member 400a facing the +Y direction and / or the -Y axis direction.

[0117] According to one embodiment, the structure for preventing the first braking member 400b from being separated has been described with respect to the first braking member 400a provided in the first rotating member 311, but the structure may be provided identically or similarly to the second braking member 400b provided in the second through groove 313b of the second rotating member 312.

[0118] Fig.13 is a diagram illustrating a first brake member according to an embodiment of the present disclosure. Fig.13 The configuration of the first braking member 400a may be Fig.10 a to Figure 12b The configuration of the first braking member 400a is completely or partially the same. For example, Fig.13 The illustrated embodiment can be used with Figures 5 to 12b Embodiments and / or Figures 14 to 17 Combination of embodiments.

[0119] In an embodiment, the braking grooves 401 and 402 (eg Figures 5 to 9b The brake groove 401 and / or 402 may include a plurality of hole areas (e.g. Figure 9a and Figure 9b The spacing between the hole areas 410a and 410b) of the first brake groove 401 may be different. For example, the spacing between the hole areas 410a and 410b may be the distance between the centers of the adjacent hole areas 410a and 410b. The spacing between the 1-1 hole area 411 and the 1-2 hole area 412 of the first brake groove 401 may be L1. For example, the spacing between the 1-2 hole area 412 and the 1-3 hole area 413 of the first brake groove 401 may be L2. For example, the spacing between the 1-3 hole area 413 and the 1-4 hole area 414 of the first brake groove 401 may be L3. In an embodiment, the state where the opening angle is about 180 degrees (for example Fig.10 The state where the opening angle is 0 degrees (e.g., C1) may correspond to the state where the first pin member 323a is disposed in the 1-1 hole region 411. Fig.10C4) in the figure may correspond to a state where the first pin member 323a is disposed in the 1-4 hole region 414. In this case, when the ratio of L1, L2, and L3 is 1:1:1, the opening angles corresponding to the states where the pin members 323a and 323b are disposed in the 1-2 hole region 412 and the 1-3 hole region 413 may be approximately 120 degrees and approximately 60 degrees, respectively. In an embodiment, the opening angle corresponding to the state where the pin members 323a and 323b are disposed in the 1-2 hole region 412 and the 1-3 hole region 413 may be increased by increasing the ratio of L3 to L1 and / or L2. For example, at least one of the opening angles corresponding to the 1-2 hole region 412 and the 1-3 hole region 413 may be an opening angle between approximately 90 degrees and approximately 180 degrees that is often used by users in practice. For example, L1 may be a1 times L3, and L2 may be a2 times L3. For example, a1 may be greater than 0 and less than about 1, and a2 may be greater than 0 and less than about 1. For example, when L1:L2:L3 is about 0.7:0.7:1, the opening angles corresponding to the 1-2 hole area 412 and the 1-3 hole area 413 may be about 128 degrees and about 75 degrees, respectively. In an embodiment, the sum of a1 and a2 may be about 1 or less. For example, when L1:L2:L3 is about 0.5:0.5:1, the opening angles corresponding to the 1-2 hole area 412 and the 1-3 hole area 413 may be about 135 degrees and about 90 degrees, respectively. For example, when L1:L2:L3 is about 0.4:0.4:1, the opening angles corresponding to the 1-2 hole area 412 and the 1-3 hole area 413 may be about 140 degrees and about 100 degrees, respectively. The above-mentioned ratios of L1, L2, and / or L3 are merely examples, and the ratios may be set and changed depending on how the electronic device is used.

[0120] For example, the usability of the foldable electronic device can be enhanced by allocating more opening angles within a range between about 90 degrees and about 180 degrees that users often use in practice, at which the fastening force of the first housing 210 and / or the second housing 220 is enhanced.

Fig.14 and Fig.15 The configuration of the second braking member 400b may be Figure 7 , Figure 8 , Figure 9b or Fig.11a and Fig.12a The second braking member 400b and / or Fig.13 The configuration of the first braking member 400a is completely or partially the same. For example, Fig.14 and Fig.15 The rotating members 311 and 312 may have Figures 5 to 8 , Fig.10 , Fig.11a and Fig.12a The rotating members 311 and 312 have different numbers and arrangements of through slots. For example, Fig.14 and Fig.15 The arm members 321 and 322 may have Figures 5 to 8 , Fig.10 , Fig.11a and Fig.12a The arm members 321 and 322 have different numbers and arrangements of pin members.

[0123] about Figure 9a and / or Fig.13 The description of the first brake member 400a can be fully applied to Figures 15 to 17 The first braking member 400a is at least partially applied to the third braking member 400c.

[0124] Reference Figures 14 to 16 In an embodiment, the braking member 400 may include a first housing 210 (eg Figures 2 to 4 The first housing 210 and the second housing 220 (eg Figures 2 to 4For example, the brake members 400 may include a first brake member 400a and a third brake member 400c disposed in the first housing 210 and a second brake member 400b and a fourth brake member 400d disposed in the second housing 220. For example, with respect to an electronic device (e.g. Figures 2 to 4 electronic device 200) or a hinge structure (eg Figures 5 to 8 In the width direction (X-axis direction) of the hinge structure 300, the second brake member 400b and the fourth brake member 400d may be mirror images of the first brake member 400a and the third brake member 400c, respectively.

[0125] According to an embodiment, the first rotating member 311 and the second rotating member 312 may include a plurality of through slots 313a and 313b, respectively. According to an embodiment, the first rotating member 311 may be included in the electronic device 200 or the hinge structure 300 (eg Figure 5 or Fig.14 The first through-groove 313a and the third through-groove 314a are spaced apart in the height direction (Z-axis direction) of the hinge structure 300. According to an embodiment, when viewed in the height direction (Z-axis direction) of the hinge structure 300, at least a portion of the third through-groove 314a may not overlap with the first through-groove 313a. For example, the third through-groove 314a may be spaced apart from the first through-groove 313a in the length direction (Y-axis direction) of the hinge structure 300. For example, the spacing between the first through-groove 313a and the third through-groove 314a in the length direction (Y-axis direction) of the hinge structure 300 may correct a display (e.g., Figures 2 to 4 230) and / or the spacing between the first through-slot 313a and the third through-slot 314a in the height direction (Z-axis direction). For example, the third braking member 400c may be at least partially accommodated in the third braking groove 403. According to an embodiment, the second rotating member 312 may include a second through-slot 313b and a fourth through-slot 314b spaced apart in the height direction (Z-axis direction) of the hinge structure 300. According to an embodiment, when viewed in the height direction (Z-axis direction) of the hinge structure 300, at least a portion of the fourth through-slot 314b may not overlap with the second through-slot 313b. For example, the fourth through-slot 314b may be spaced apart from the second through-slot 313b in the length direction (Y-axis direction) of the hinge structure 300. For example, the spacing between the second through-slot 313b and the fourth through-slot 314b in the length direction (Y-axis direction) of the hinge structure 300 may correct the display (for example Figures 2 to 4The display 230 of FIG. 20 is a display 230 of FIG. 20 and / or a distance between the second through groove 313b and the fourth through groove 314b in the height direction (Z-axis direction). For example, the fourth braking member 400d may be at least partially accommodated in the fourth braking groove (not shown).

[0126] Reference Figures 14 to 16 In an embodiment, the arm members 321 and 322 may include a plurality of pin members 323a, 323b, 324a, and 324b connected to the plurality of braking members 400a, 400b, 400c, and 400d. In an embodiment, the first arm member 321 may include a first pin member 323a at least partially accommodated in the first braking groove 401 and a third pin member 324a at least partially accommodated in the third braking groove 403. For example, the third pin member 324a may be spaced apart from the first pin member 323a in the height direction (Z-axis direction) of the hinge structure 300. For example, the third pin member 324a may be spaced apart from the first pin member 323a in the length direction (Y-axis direction) of the hinge structure 300. For example, each of the spacings between the first pin member 323a and the third pin member 324a in the length direction (Y-axis direction) and / or the height direction (Z-axis direction) of the hinge structure 300 can be substantially the same as the spacings between the first brake member 400a and the third brake member 400c in the length direction (Y-axis direction) and / or the height direction (Z-axis direction) of the hinge structure 300.

[0127] In an embodiment, the second arm member 322 may include a second pin member 323b at least partially accommodated in the second detent groove 402 and a fourth pin member 324b at least partially accommodated in a fourth detent groove (not shown). For example, the fourth pin member 324b may be spaced apart from the second pin member 323b in the height direction (Z-axis direction) of the hinge structure 300. For example, the fourth pin member 324b may be spaced apart from the second pin member 323b in the length direction (Y-axis direction) of the hinge structure 300. For example, each of the spacings between the second pin member 323b and the fourth pin member 324b in the length direction (Y-axis direction) and / or the height direction (Z-axis direction) of the hinge structure 300 may be substantially the same as the spacings between the second detent member 400b and the fourth detent member 400d in the length direction (Y-axis direction) and / or the height direction (Z-axis direction) of the hinge structure 300.

[0128] In an embodiment, the third brake member 400c (e.g., the third brake hole) may include a plurality of hole regions 430a and at least one connection region 440a connected to the third pin member 324a. For example, the third brake member 400c may include a fifth hole region 431, a sixth hole region 432, a seventh hole region 433, and / or an eighth hole region 434. For example, the third brake member 400c may include a fourth connection region 441, a fifth connection region 442, and / or a sixth connection region 443. In an embodiment, the first pin member 323a and the third pin member 324a may be based on the first housing 210 (e.g., Figures 2 to 4 The first housing 210) and / or the second housing 220 (eg Figures 2 to 4 The first and third detent grooves 401 and 403 are slid along the first and third detent grooves 401 and 403 by the rotation of the second housing 220. For example, the first pin member 323a and the third pin member 324a can move substantially simultaneously. For example, when the opening angle is about 180 degrees, the first pin member 323a can be positioned in the 1-1 hole region 411, and the third pin member 324a can be positioned in the fifth hole region 431 (for example, Fig.16 For example, when the opening angle is 0 degrees, the first pin member 323a can be positioned in the 1st-4th hole area 414, and the third pin member 324a can be positioned in the eighth hole area 434. For example, since the first pin member 323a and the third pin member 324a are respectively arranged in the hole areas 410a and 430a, when the opening angle is about 180 degrees and / or 0 degrees, the fastening force of the first housing 210 and / or the second housing 220 can be enhanced at about 180 degrees and / or 0 degrees compared to when only the first brake member 400a is provided. Fig.16 and Fig.17 The description of the third brake member 400c can be applied similarly to Fig.14 and Fig.15 For example, with respect to the width direction (X-axis direction) of the hinge structure 300, the fourth braking member 400d may be a mirror image of the second braking member 400b.

[0129] According to an embodiment, the third brake member 400c may additionally provide a plurality of opening angles at which the fastening force of the first housing 210 and / or the second housing 220 is enhanced. For example, the opening angle provided by the third brake member 400c at which the fastening force of the first housing 210 and / or the second housing 220 is enhanced may be partially different from the opening angle of the first brake member 400a. For example, the opening angle corresponding to the state in which the third pin member 324a is disposed in the sixth hole region 432 may be different from the opening angle state in which the first pin member 323a is disposed in the 1-2 hole region 412 and / or the 1-3 hole region 413. For example, the opening angle corresponding to the state in which the third pin member 324a is disposed in the seventh hole region 433 may be different from the opening angle state in which the first pin member 323a is disposed in the 1-2 hole region 412 and / or the 1-3 hole region 413. For example, in a state where the first pin member 323a is disposed in the 1-2nd hole region 412 or the 1-3rd hole region 413, the third pin member 324a may be positioned in any one of the connection regions 440a.

[0130] although Fig.17 An example in which the first brake member 400a and the third brake member 400c are aligned and arranged is shown, but this is only a conceptual illustration and does not limit the arrangement relationship between the first brake member 400a and the third brake member 400c.

[0131] Fig.18a is an exploded perspective view showing some components of a hinge structure according to an embodiment of the present disclosure. Fig.18b The present invention is a diagram showing an embodiment of the present invention. Fig.18a A perspective view of a cross section of some components of a hinge structure being connected.

[0132] Fig.18a and Fig.18b The hinge structure 300 may include a first rotating member 311, a first arm member 321 that rotates and slides in coordination with the first rotating member 311, and a pin elastic member (323c). Hereinafter, the hinge structure 300 will be described with respect to the first rotating member 311 and the first arm member 321, but the related description may be related to the second rotating member (e.g. Figure 7 and Figure 8 312) and a second arm member (eg Figure 7 and Figure 8 322) are designed the same or similarly.

[0133] Fig.18a and Fig.18b The hinge structure can be configured with Figures 4 to 17 The configuration of the hinge structure is completely or partially the same. Fig.18a and Fig.18bThe components of the hinge structure can be selectively connected with Figures 4 to 17 The components of the hinge structure are combined.

[0134] According to an embodiment, the pin elastic member (323c) may be formed in the through groove (313c) formed in the first rotating member (311). Figure 7 . According to an embodiment, the through groove 313c may have a fixed shape and a predetermined thickness in the width direction (X-axis direction) of the hinge structure 300. For example, at least a portion of the elastic pin member 323c may be accommodated in the through groove 313c formed in the first rotating member 311. The through groove 313c may have a shape surrounding at least a portion of the accommodated pin elastic member 323c.

[0135] According to an embodiment, the cross section of the pin elastic member 323c in the width direction (X-axis or Y-axis direction) may correspond to a circular shape. However, the cross-sectional shape of the pin elastic member 323c in the width direction is not limited to a circular shape. For example, the cross section of the pin elastic member 323c in the width direction may have various shapes, such as an ellipse or a polygon (e.g., a quadrilateral or a pentagon).

[0136] According to an embodiment, the through groove 313c formed in the first rotating member 311 may have a fixed shape without elasticity and may have a shape similar to Figures 7 to 14 The shape of the through groove 313c may be formed by a combination of a plurality of hole regions and a connection region, such as Figure 9a , Figure 9b and Fig.13 According to the embodiment, the pin elastic member 323c can slide in the through groove 313c, and the elastic force of the pin elastic member 323c itself can form a force that restricts the sliding movement according to the interval.

[0137] According to an embodiment, the pin elastic member 323c may include a groove with one end open so as to provide elastic force in the through groove 313c. The groove has different intervals corresponding to the area of ​​the through groove 313c (e.g., the hole area and the connection area are arranged alternately), so that the edge of the through groove 313c (e.g., the inner side of the first rotating member 311) can provide different elastic forces. According to an embodiment, the pin elastic member 323c is formed by a support body for maintaining the rigidity of the core part so as to provide elastic force in the through groove 313c, and the outer peripheral surface of the core can be formed so that the elastic layer formed by the elastic material surrounds the core part. Corresponding to the area of ​​the through groove 313c (e.g., the hole area and the connection area are arranged alternately), the elastic layer can provide different elastic forces to the edge of the through groove 313c (e.g., the inner side of the first rotating member 311).

[0138] According to an embodiment, at least a portion of the pin elastic member 323c may be formed of an elastomer. The elastomer of the pin elastic member 323c may include various materials that provide an elastic force equal to or greater than a specified value. According to an embodiment, at least a portion of the pin elastic member 323c may include a metal such as nickel and chromium. For example, at least a portion of the pin elastic member 323c may include austenitic stainless steel. As another example, at least a portion of the pin elastic member 323c may include a spring metal such as 304 stainless steel or 301 stainless steel.

[0139] According to an embodiment, the pin elastic member (323c) provides a force (eg, a fixing force) to the first rotating member 311, and the first housing (eg, Figure 4 210 in the embodiment) and a second housing (eg Figure 4 220) can be positioned at any angle. For example, the pin elastic member 323c can provide a force (e.g., elastic force) acting in the width direction. For example, when the pin elastic member 323c has a circular cross-section in the width direction, the force (e.g., elastic force) provided by the pin elastic member 323c can act on the outer peripheral surface of the pin elastic member 323c in the normal (vertical) direction.

[0140] An electronic device (e.g., a portable terminal) includes a display having a flat surface or having both a flat surface and a curved surface. Due to the fixed display structure, the electronic device including the display may have limitations in realizing a screen larger than the size of the electronic device. Therefore, a foldable electronic device is being studied. For example, for user convenience, when opening or closing two shells, the foldable device can implement a free stop function capable of fixing the opening angle. For example, the free stop function can typically be implemented in a manner where a compression force is provided to a cam structure by an elastic member, and the cam structures engage with each other at a specific rotation angle of the hinge. For example, when manufacturing a complex cam structure, a cam-type free stop structure may require high dimensional accuracy. For example, the elastic member that pressurizes the cam structure can extend in the length direction of the interlocking axis in the hinge structure and increase the installation space of the entire hinge structure.

[0141] According to an embodiment of the present disclosure, a hinge structure that uses an elastic braking member (e.g., a braking spring) to realize a free stop function without a cam structure and an electronic device including the hinge structure can be provided. The present disclosure is not limited to the aforementioned embodiments of the present disclosure, but various modifications or changes can be made thereto without departing from the spirit and scope of the present disclosure.

[0142] According to an exemplary embodiment of the present disclosure, an electronic device (eg Figure 1 101 or Figures 2 to 4 200) may include: a first housing (eg Figures 2 to 4 The first housing 210), the hinge structure (eg Figure 4 280 or Figure 5 and Fig.14 300) and / or a display (eg Figure 2 and Figure 4 230). The hinge structure may rotatably connect the second housing to the first housing. At least a portion of the display may be bendable in response to the rotation. According to example embodiments, the hinge structure may include a first rotating member (e.g. Figures 5 to 8 and Figure 10 to Figure 12b 311 or Figures 14 to 16 311), a second rotating member (eg Figures 5 to 8 , Fig.10 , Fig.11a and Fig.12a 312 or Fig.14 and Fig.15 312), a first braking member (eg Figures 7 to 9a and Figures 11a to 12b 401, Fig.13 401 or Figures 14 to 17 401), a second braking member (eg Figure 7 , Figure 8 , Figures 9b to 11a and Fig.12a 402 or Fig.14 and Fig.15 402), a first pin member (eg Figure 7 , Figure 8 , Figure 10 to Figure 12b 323a or Figures 14 to 16 323a) and / or a second pin member (eg Figure 7 , Figure 8 , Fig.10 , Fig.11a and Figure 12b 323b or Figures 14 to 16 The first rotating member may be coupled to the first housing and rotate about a first rotation axis (eg, Figure 5 The second rotating member may be coupled to the second housing and rotate about a second rotating axis (eg, Figure 5 The first braking member may be disposed in the first rotating member and may include a first braking groove (eg, Figure 9a , Fig.11b and Figure 12b The second braking member may be disposed in the second rotating member and may include a second braking groove (eg, Figure 9b 402). The first pin member may be slidably connected to the first brake groove. The second pin member may be slidably connected to the second brake groove. The first brake member may be configured to extend in the width direction of the first pin member (e.g., by Fig.11bThe second brake member may be configured to provide an elastic force to the first pin member in the width direction of the second pin (for example, in the direction indicated by the arrow in FIG. Fig.11b For example, the first pin member and / or the second pin member may be configured to slide in coordination with the rotation of the first housing and / or the second housing.

[0143] According to example embodiments, the first brake member may be configured to provide an elastic force in a direction perpendicular to the axis of the first pin member.The second brake member may be configured to provide an elastic force in a direction perpendicular to the axis of the second pin member.

The second brake member may be configured to provide an elastic force to press an outer peripheral surface of the second pin member in at least one direction.

[0145] According to example embodiments, each of the elastic forces of the first brake member and the second brake member may be a first specified value or greater. For example, when an external force equal to or less than the first specified value is applied to at least one of the first housing or the second housing, the angle between the first housing and the second housing may be maintained.

[0146] According to example embodiments, the first brake member (eg, the first brake groove) may include at least one first hole region (eg, Figure 9a The second brake member (e.g., the second brake groove) may include at least one second hole area (e.g., the second hole area) that receives at least a portion of the second pin member.

The second pin may be configured to receive a greater elastic force based on being positioned in the at least one second connection region than in the plurality of second hole regions.

The second pin may be configured to elastically deform the at least one second connection region based on being positioned in the at least one second connection region.
