[0024] Battery 189 can power at least one component of electronic device 101. According to an embodiment, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, or a fuel cell.

[0025] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). The communication module in the embodiment can communicate with external electronic device 104 via a first network 198 (e.g., a short-range communication network such as Bluetooth, 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 fifth-generation (5G) network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can use user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196 to identify or verify electronic device 101 in the communication network (such as the first network 198 or the second network 199).

[0026] Wireless communication module 192 can support 5G networks beyond fourth-generation (4G) networks and next-generation communication technologies (e.g., new radio (NR) access technologies). NR access technologies can support high-speed transmission for large-capacity data (enhanced mobile broadband (eMBB)), terminal power minimization and multi-terminal access (massive machine-type communication (mMTC)) or ultra-reliable low-latency communication (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave (mmWave) bands) to achieve, for example, higher data rates. Wireless communication module 192 can support various technologies, such as beamforming, massive MIMO, full-dimensional MIMO, array antennas, analog beamforming, or massive antennas, to ensure performance in high-frequency bands. Wireless communication module 192 can support various requirements defined in electronic device 101, external electronic devices (e.g., electronic device 104), or network systems (e.g., second network 199). According to one embodiment, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or greater) for eMBB implementation, lost coverage (e.g., 164 dB or less) for mMTC implementation, or user plane (U plane) latency (e.g., 0.5 ms or less, or 1 ms or less round trip for each of the downlink (DL) and uplink (UL) for URLLC implementation).

[0027] Antenna module 197 can transmit or receive signals or power to or from the exterior of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a PCB). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190. Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally incorporated into antenna module 197.

[0028] According to an embodiment, antenna module 197 can 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 multiple antennas (e.g., an array antenna), wherein the RFIC is disposed on a first surface (e.g., a bottom surface) of the printed circuit board, or is configured to be adjacent to the first surface to support a specified high-frequency band (e.g., a millimeter-wave band), and the multiple antennas are disposed on a second surface (e.g., a top surface or a side surface) of the printed circuit board, or are configured to be adjacent to the second surface to transmit or receive signals having a specified high-frequency band.

[0029] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0030] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to the second network 199. Each of external electronic device 102 or external electronic device 104 may be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or part of the operations to be performed on electronic device 101 may be performed on one or more external electronic devices, such as external electronic device 102, external electronic device 104, or server 108. For example, when electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may additionally request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, one or more external electronic devices may perform the requested function or service, or additional functions or services associated with the request, and provide the result of the performance to electronic device 101. Electronic device 101 may process the result as is or additionally, and provide the result of the processing as at least part of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used. For example, electronic device 101 may provide ultra-low latency services by using, for example, distributed computing or mobile edge computing. In another embodiment, external electronic device 104 may include an Internet of Things (IoT) device. Server 108 may be an intelligent server using machine learning and / or neural networks. According to an embodiment, external electronic device 104 or server 108 may be included in a second network 199.

[0031] Figure 2 This is a view illustrating an example of a first state of an electronic device according to an embodiment of the present disclosure. Figure 3 This is a view illustrating an example of a second state of an electronic device according to an embodiment of the present disclosure. As an example, Figure 2 State 11a corresponds to an example view showing the front and side surfaces of the electronic device in the retracted position, and Figure 2 State 11b corresponds to a view showing an example of the rear surface of an electronic device in an extended position. Figure 3 State 12a corresponds to an example view showing the front and side surfaces of an electronic device in an extended position, and Figure 3State 12b corresponds to a view showing an example of the rear surface of an electronic device in the retracted position.

[0032] Reference Figure 2 and Figure 3 The electronic device 101 according to the embodiment may include a first housing 210 (or base housing, base structure or first cover), a second housing 220 (or front housing, front decorative member, front frame or second cover), a first housing 410 (or movable housing, sliding plate, sliding housing, sliding structure, sliding shell, sliding body, sliding frame, sliding bracket or first frame), a second housing 420 (or second frame, fixing plate, fixing housing, fixing frame or fixing bracket) and a display assembly 360.

[0033] In embodiments, electronic device 101 may be a sliding or rollable type of electronic device, and the state of electronic device 101 may be changed by movement of the second housing 220 relative to the first housing 210 (or movement of the first housing 410 relative to the second housing 420). For example, the state of electronic device 101 may include states 11a and 11b (e.g., retracted position, closed mode, shrunken mode, slide-in mode, or minimum size mode) and states 12a and 12b (e.g., extended position, open mode, expanded mode, slide-out mode, or maximum size mode). States 11a and 11b, and states 12a and 12b of electronic device 101 may be determined based on the relative position of the second housing 220 relative to the first housing 210. Electronic device 101 may be changed (or switched) between states 11a and 11b, and between states 12a and 12b, by user manipulation or mechanical operation (e.g., a motor).

[0034] In embodiments, states 11a and 11b of electronic device 101 may represent a state in which the area (or size) of the exposed region of display assembly 360 exposed to (or defining) the front surface of electronic device 101 (e.g., the surface facing the +z axis direction) is relatively reduced compared to states 12a and 12b. States 12a and 12b of electronic device 101 may represent a state in which the area (or size) of the exposed region of display assembly 360 exposed to (or defining) the front surface of electronic device 101 (e.g., the surface facing the +z axis direction) is relatively expanded compared to states 11a and 11b. For example, states 11a and 11b may represent a state in which the exposed region of display assembly 360 visually exposed to the front surface of electronic device 101 has a minimum size, and states 12a and 12b may represent a state in which the exposed region of display assembly 360 exposed to the front surface of electronic device 101 has a maximum size. Although not shown, the states of electronic device 101 may also include at least one intermediate state (e.g., a partially extended state or a partially open state) defined between states 11a and 11b and between states 12a and 12b. For example, at least one intermediate state may represent one or more states in which the size of the exposed area of ​​display assembly 360 is larger than the size of states 11a and 11b and smaller than the size of states 12a and 12b.

[0035] In embodiments, at the retracted positions corresponding to states 11a and 11b, the first housing 210 and the second housing 220 of the electronic device 101 can be in a closed state. As an example, the first housing 210 may include a lower end 210_sd3 (or a first lower side portion), an upper end 210_sd4 (or a first upper side portion), a right portion 210_sd1 (or a first right side portion), a left portion 210_sd2 (or a first left side portion), and a bottom portion. The second housing 220 may include a upper end 220_fr (or a second upper side portion), a right portion 220_sd1 (or a second right side portion), and a left portion 220_sd2 (or a second left side portion). Additionally, a bottom portion may also be provided on the rear surface of the second housing 220. As another example, the electronic device 101 may include a configuration integrating the first housing 410 and the second housing 220. In this case, the second housing 220 may be integrated as a decorative component of the first housing 410. A rear cover 440 may be disposed on the rear surface of the electronic device 101. The rear cover 440 may include a first rear cover 441 disposed in a direction along the rear surface of the first housing 210 and a second rear cover 442 disposed in a direction along the rear surface of the second housing 220. As an example, the first rear cover 441 may be disposed below the bottom of the first housing 210. The second rear cover 442 may be disposed in a downward direction (e.g., the -z axis direction) of the second housing 220 (or below the bottom of the second housing 220). In states 11a and 11b, the first housing 210 and the second housing 220 of the electronic device 101 may be positioned close to each other within a predetermined distance. As an example, in states 11a and 11b, one side end of the right portion 210_sd1 of the first housing and one side end of the right portion 220_sd1 of the second housing may contact each other, or may be positioned close to each other within a specific distance (e.g., a few micrometers to a few millimeters). As an example, in states 11a and 11b, one side of the left portion 210_sd2 of the first housing and one side of the left portion 220_sd2 of the second housing can be in contact with each other, or can be configured to be close to each other within a certain distance. Optionally, in states 12a and 12b, one side of the first housing 210 (e.g., the end in the y-axis direction) and one side of the second housing 220 (e.g., the end in the -y-axis direction) can be in contact with each other, or can be spaced apart from each other by a predetermined second gap (e.g., a gap having a length greater than the length of the first gap or a gap of several millimeters to several centimeters or more).

[0036] In this embodiment, referring to states 12a and 12b, when the second housing 220 slides relative to the first housing 210, the second housing 220 can change the state of the electronic device 101. For example, when the second housing 220 moves relative to the first housing 210 in a first direction (or the y-axis direction), the electronic device 101 can change from states 11a and 11b to states 12a and 12b. Conversely, when the second housing 220 moves relative to the first housing 210 in a second direction (or the -y-axis direction) opposite to the first direction, the electronic device 101 can change from states 12a and 12b to states 11a and 11b.

[0037] In an embodiment, in electronic device 101, the size of the exposed area of ​​display assembly 360 visually exposed to the front surface of electronic device 101 can change in response to sliding of the second housing 220. Display assembly 360 can be configured such that, while supported by other components of electronic device 101, at least a portion of display assembly 360 rotates and moves linearly in response to sliding of the second housing 220, causing the area exposed to the front surface of electronic device 101 to expand or contract. Display assembly 360 may include at least partially flexible portions. For example, the display included in display assembly 360 may be a flexible display.

[0038] In an embodiment, at the retracted position shown in states 11a and 11b, the display assembly 360 may include a first screen region 261 defining a front surface and a first extension region 263 and a second extension region 262 extending from the first screen region 261 and disposed within the first housing 210. The first extension region 263 may be located between the first screen region 261 and the second extension region 262 at the retracted position and may include a region defining a curved surface. The second extension region 262 may include a region configured to face the bottom surface of the first housing 210 at the retracted position. The second extension region 262 may include a non-display area in at least a portion of which no pixels are disposed. Optionally, the entire second extension region 262 may include a display area.

[0039] In an embodiment, in the retracted position, at least a portion of the first extension region 263 may be covered by the upper end 210_sd4 of the first housing, and the second extension region 262 may be disposed between the lower portion of the second housing 420 and the bottom surface (e.g., the bottom of the first housing) of the first housing 210. In the extended position shown in states 12a and 12b, the display assembly 360 may include a first screen region 261 defining a front surface and at least a portion of the first extension region 263 and the second extension region 262 extending from the first screen region 261. In the extended position, the first extension region 263 may be disposed on the front surface together with the first screen region 261. Optionally, in the extended position, the first screen region 261, the first extension region 263, and the second extension region 262 may define the front surface of the display assembly 360. The electronic device 101 may have a partially retracted position or a partially extended position corresponding to the position between the retracted position and the extended position. In this configuration, in the retracted position or in the rearward direction (e.g., the -z-axis direction), a portion of the second extension region 262 (or a region in which pixels for screen display are disposed and is disposed in the rearward direction of the first screen region 261 in the retracted position) may be disposed on the front surface (e.g., a surface observable from the outside), and another portion of the second extension region 262 may be positioned facing the curved region where the first extension region 263 is disposed. Optionally, in the partially retracted position, a portion of the second extension region 262 may be disposed on the front surface, and in the retracted position, another portion of the second extension region 262 may be disposed in the curved region where the first extension region 263 is disposed. Optionally, the size of the area of ​​the second extension region 262 disposed on the front side may vary depending on the degree of partial retraction (or partial extension). As an example, with the screen areas (e.g., the first screen area 261, the first extension area 263, and the second extension area 262) included in the display assembly 360 positioned at an extension on the front surface, the first housing 410 may be partially exposed when the side surface of the electronic device 101 is viewed, and the second housing 420 may be partially exposed when the rear surface of the electronic device 101 is viewed.

[0040] When the first housing 210 slides relative to the second housing 220 (or the second housing 220 slides relative to the first housing 210), the second extension region 262 can be inserted into the interior of the first housing 210 (e.g., a slide-in operation) or pulled out to the exterior of the first housing 210 (e.g., a slide-out operation). In the embodiments disclosed in this disclosure, the first screen region 261, the first extension region 263, and the second extension region 262 of the display 260 are not physically distinct regions, and do not necessarily indicate that their shapes or properties are different.

[0041] The structure of the electronic device 101 described below corresponds to an example of an electronic device 101 with a variable screen display area, and the electronic device 101 with a variable screen display area can be implemented in various ways in addition to the structures disclosed in this disclosure. In this disclosure, the term "state" can be understood to refer to the operation of the electronic device 101 or the structural form, shape, or configuration of the display.

[0042] Figure 4 This is an exploded perspective view showing an electronic device according to an embodiment of the present disclosure.

[0043] Reference Figures 2 to 4 The electronic device 101 according to an embodiment may include a first housing 210, a second housing 220, a display assembly 360, a first housing 410, side members 481 and 482, a second housing 420, a first-type auxiliary structure 300 (or structure, first-type structure, display support structure, or structure for damage prevention and for waterproofing or dustproofing), and a rear cover 440 (or back cover). For example, the electronic device 101 may be a foldable electronic device or a rollable electronic device.

[0044] According to an embodiment, the first housing 210 may define at least a portion of the appearance of the electronic device 101. The first housing 210 provides space in which various electronic components are disposed. The second housing 220 may be slidably connected to the first housing 210. For example, the second housing 220 may be movable from the first housing 210 on the +y axis, or may be moved to the first housing 210 on the -y axis. However, this is by way of example, and the direction of movement of the second housing 220 is not limited thereto. For example, the second housing 220 may be configured to be withdrawn from the first housing 210 on the +x axis or moved to the first housing 210 on the -x axis, such that the display 260 expands in the width direction (e.g., the x-axis direction) (e.g., to the right or left) of the electronic device 101. In this case, the electronic device 101 may be altered such that the structure of the currently shown figure slides in the x-axis direction.

[0045] According to an embodiment, as described above, the first housing 210 may include a lower end 210_sd3 (or a lower side portion), an upper end 210_sd4 (or an upper side portion), a right portion 210_sd1, a left portion 210_sd2, and a bottom portion 210_bt. The upper end 210_sd4 may extend parallel to the bottom portion 210_bt in the y-axis direction from the upper portion of the lower end 210_sd3. The length of the upper end 210_sd4 in the y-axis direction may be shorter than the length of the bottom portion 210_bt in the y-axis direction. The lengths of the right portion 210_sd1, the left portion 210_sd2, and the bottom portion 210_bt in the y-axis direction may be the same. A portion of the printed circuit board 204, the battery 205, the first housing 410, and the second housing 420 may be housed within the first housing 210. A portion of the rear cover 440 (e.g., a first rear cover 441) may be disposed below the bottom of the first housing 210_bt. The first housing 210 may define a housing recess 210_rc including a lower end 210_sd3, an upper end 210_sd4, a portion of the right side 210_sd1, a portion of the left side 210_sd2, and a portion of the bottom 210_bt. A first type auxiliary structure 300 may be disposed in the housing recess 210_rc. At least a portion of the display assembly 360 may be disposed in the housing recess 210_rc. The first type auxiliary structure 300 and a portion of the display assembly 360 (e.g., a first extension region 263) may be disposed in the housing recess 210_rc facing each other.

[0046] According to an embodiment, while the first type of auxiliary structure 300 is moving toward the bottom surface of the housing recess 210_rc or moving in the y-axis direction, the first type of auxiliary structure 300 can further move in the -y-axis direction. As an example, the first type of auxiliary structure 300 can be fixed to the inner surface of the lower end 210_sd3 of the first housing (e.g., the bottom surface of the lower end 210_sd3 of the first housing as seen in the y-axis direction or the surface opposite to the lower end 210_sd3 as seen from the outside). Responding to the processor of the electronic device 101 (e.g., ... Figure 1 Under the control of the processor 120, at least a portion of the first type of auxiliary structure 300 can move in the y-axis direction (or toward the first extension region 263).

[0047] According to an embodiment, the second housing 220 may include a portion (e.g., the upper part 220_fr of the second housing) surrounding at least a portion of the upper periphery (e.g., the -y axis periphery) of the display assembly 360 or the first housing 410, a left portion 220_sd2 of the second housing extending in the -y axis direction from one side periphery (e.g., the left side periphery) of the upper part 220_fr of the second housing in the -y axis direction, and a right portion 220_sd1 of the second housing extending in the -y axis direction from the opposite side periphery (e.g., the right side periphery) of the upper part 220_fr of the second housing in the -y axis direction. The second housing 220 may be C-shaped and may be fastened (or coupled) to the first housing 410 from the -y axis direction to the y axis direction. At least a portion of the first housing 210 (e.g., the left portion 210_sd2 and the right portion 210_sd1 of the first housing) and at least a portion of the second housing 220 (e.g., the left portion 220_sd2 and the right portion 220_sd1 of the second housing) may be configured to face each other.

[0048] According to an embodiment, at least a portion of the first housing 410 may be located within the internal space of the electronic device 101 defined by the first housing 210 and the second housing 220. At least a portion of the first housing 410 may be coupled to or integrally formed with the second housing 220. The second housing 220 and the first housing 410 may define a first frame (or a first frame structure or first frame) capable of withstanding a specific level or higher of load to contribute to the durability or rigidity of the electronic device 101. Electronic components or various components associated with electronic components may be disposed on or supported by the first frame. The first housing 410 may support at least a portion of the display assembly 360 in a rearward direction (e.g., the -z direction). The first housing 410 may support at least a portion of the display 260 (e.g., the first screen area 261). The first housing 410 may be attached (or joined) to at least a portion of the display 260 (e.g., the first screen area 261 of the display 260) by means of an adhesive member (not shown). The first housing 410 may linearly reciprocate in the +y / -y direction. The first housing 410 can slide relative to the first housing 210 together with the second housing 220.

[0049] According to an embodiment, a second housing 420 (or a mounting bracket, mounting support structure, mounting support member, mounting frame, or first plate) may be located within the internal space of the electronic device 101 defined by the first housing 210. The second housing 420 may be connected to the first housing 210. Optionally, at least a portion of the second housing 420 may be integrally formed with the first housing 210. The first housing 210 and the second housing 420 may define a second frame (or a second frame structure or second frame) capable of withstanding a specific level or higher of load to contribute to the durability or rigidity of the electronic device 101. Electronic components or various components associated with electronic components may be disposed on or supported by the second frame. As an example, a battery 205 and a printed circuit board 204 may be disposed on or supported by the second housing 420 or the second frame.

[0050] According to an embodiment, the second housing 420 may support at least a portion of the display 260 (e.g., at least a portion of the first extension region 263 and the second extension region 262). As an example, the second housing 420 may include a curved region 421 and may be positioned toward the first extension region 263 of the display 260 depending on the retracted or extended position of the electronics 101. When the second housing 220 slides, the first extension region 263 and the second extension region 262 of the display 260 may be withdrawn from or inserted into the interior space of the first housing 210.

[0051] According to an embodiment, side members 481 and 482 can guide the movement path of the display assembly 360 when the second housing 220 slides relative to the first housing 210. As an example, side members 481 and 482 can be connected to the first housing 210 and can remain stationary when the second housing 220 slides relative to the first housing 210. As another example, side members 481 and 482 can be connected to the second housing 220 and can slide together with the second housing 220 relative to the first housing 210. At least one side member 481 and 482 can be provided. As an example, a pair of side members 481 and 482 can be provided and can be located on opposite sides of the first housing 210 (e.g., in the -x and +x directions). As an example, the first side member 481 on the right side of side members 481 and 482 can be connected to a side of the first housing 210 (e.g., the end in the -x direction), and the second side member 482 on the left side of side members 481 and 482 can be connected to the opposite side of the first housing 210 (e.g., the end in the +x direction). However, this is just an example, and the position and / or number of side members 481 and 482 are not limited thereto.

[0052] According to an embodiment, at least a portion of the display assembly 360 may be supported by at least any one of the first housing 210, the second housing 220, the first housing 410, or the second housing 420. As an example, a portion of the display assembly 360 may be supported by the first housing 410, and another portion of the display assembly 360 may be supported by the second housing 420. When the second housing 220 moves relative to the first housing 210 (or the first housing 410 moves relative to the second housing 420), the display area of ​​the display assembly 360 may be altered. As an example, when the first housing 410 is removed from the second housing 420, the area of ​​the display 260 of the display assembly 360 may be visually exposed, and the area of ​​the screen displaying the display 260 may be expanded into a first screen area 261, a first extended area 263, and a second extended area 262. When the first housing 410 is inserted into the second housing 420, the visually exposed area of ​​the display 260 of the display assembly 360 may be reduced, and the area of ​​the screen displaying the display 260 may be reduced to the first screen area 261. Display assembly 360 may include a display, a support plate, and a multi-bar assembly (or a multi-joint hinge structure or support structure). However, this is by way of example, and the configuration of display assembly 360 is not limited thereto. As an example, display assembly 360 may include various layers (such as a cover layer and / or a touch panel).

[0053] According to an embodiment, the display 260 can visually display information. The display 260 can be configured such that at least a portion of the display 260 is flexible. When the second housing 220 moves relative to the first housing 210 (or when the first housing 410 moves relative to the second housing 420), the display area of ​​the display 260 that is visually exposed to the outside can be changed. In the following, for ease of description, the direction in which information is visually displayed by the display 260 relative to the display 260 will be referred to as the forward direction (e.g., the +z direction), and the direction opposite to the forward direction will be referred to as the backward (or rearward) direction (e.g., the -z direction).

[0054] According to an embodiment, a rear cover 440 may be disposed on or coupled to the rear surfaces of the first housing 210 and the second housing 220 to define at least a portion of the appearance of the electronic device 101. As an example, the rear cover 440 may include a first rear cover 441 coupled to the first housing bottom 210_bt of the first housing 210 and a second rear cover 442 coupled to the rear surface of the second housing 220. The rear cover 440 may provide a decorative effect on the appearance of the electronic device 101.

[0057] Reference Figures 2 to 5As described above, the first housing 210 may include a lower end 210_sd3, an upper end 210_sd4, a right side 210_sd1, a left side 210_sd2, and a bottom 210_bt. The bottom 210_bt may have a surface with dimensions similar to or the same as the bottom surface of the second housing 420 described above. Optionally, the bottom 210_bt may have dimensions corresponding to the dimensions of the first rear cover 441. The bottom 210_bt may include at least one hole passing through it in the forward and backward directions (e.g., the z-axis direction and the -z-axis direction). The right portion 210_sd1 of the first housing may be disposed on the right periphery of the bottom portion 210_bt of the first housing. The right portion 210_sd1 extends and has a predefined height (e.g., a height corresponding to the thickness of the electronic device 101) at an angle to the bottom surface of the bottom portion 210_bt (or perpendicular to the bottom surface of the bottom portion 210_bt or the z-axis direction). The left portion 210_sd2 of the first housing may be disposed on the left periphery of the bottom portion 210_bt of the first housing. The left portion 210_sd2 extends and has a predefined height (e.g., a height corresponding to the thickness of the electronic device 101) at an angle to the bottom surface of the bottom portion 210_bt (or perpendicular to the bottom surface of the bottom portion 210_bt or the z-axis direction). The lower end 210_sd3 of the first housing may be disposed at the lower periphery of the bottom 210_bt of the first housing, wherein the lower end 210_sd3 of the first housing extends and has a predetermined height (e.g., a height corresponding to the thickness of the electronic device 101) at an angle to the bottom surface of the bottom 210_bt of the first housing (or perpendicular to the bottom surface of the bottom 210_bt of the first housing or in the z-axis direction). The periphery of the opposite side of the lower end 210_sd3 of the first housing may be connected to the upper end of one side of the left part 210_sd2 of the first housing and the upper end of one side of the right part 210_sd1 of the first housing. The upper end 210_sd4 of the first housing may be configured to extend from the upper periphery (e.g., the periphery in the z-axis direction) of the lower end 210_sd3 of the first housing towards the y-axis direction. Accordingly, the lower periphery of the upper end 210_sd4 of the first housing can be connected to the upper periphery of the lower end 210_sd3 of the first housing, and the periphery on the opposite side of the upper end 210_sd4 of the first housing can be connected to one side of the left part 210_sd2 and one side of the right part 210_sd1 of the first housing. According to an embodiment, the lower periphery of the first housing 210 (e.g., the periphery in the -y axis direction) can be closed by the lower end 210_sd3 of the first housing.Optionally, a housing recess 210_rc (or groove or structural arrangement recess) formed by the lower end 210_sd3, the upper end 210_sd4, a portion of the left portion 210_sd2, and a portion of the right portion 210_sd1 of the first housing can be provided (formed) at the lower periphery of the first housing 210. A first type auxiliary structure 300 can be provided (or fixed to) the housing recess 210_rc. According to an embodiment, the y-axis length of the upper end 210_sd4 of the first housing can be formed to be different from the y-axis length of at least one of the right portion 210_sd1 or the left portion 210_sd2 of the second housing. For example, the y-axis length of the upper end 210_sd4 of the first housing can be smaller than the y-axis length of the right portion 210_sd1 of the first housing. Optionally, the y-axis length of the upper end 210_sd4 of the first housing can be formed to be smaller than or similar to the height of the lower end 210_sd3 of the first housing.

[0058] Reference Figures 2 to 5 Status 503 and Status 505 and Figure 6 At least a portion of the first type of auxiliary structure 300 may include a structural substrate 310 (or substrate), a support structure 320 (or protective structure) and a plurality of actuators 330.

[0059] The structural substrate 310 may include a base substrate 310_bd formed such that its length in the x-axis direction is longer than its length in the z-axis or y-axis direction. As an example, one side length of the base substrate 310_bd (e.g., length in the x-axis direction) may have a dimension similar to or the same as (or smaller than) one side length of the housing recess 210_rc of the first housing 210 (e.g., length in the x-axis direction). The base substrate 310_bd may be fixed to the bottom surface of the housing recess 210_rc. The base substrate 310_bd may include a plurality of holes 310_h, in which at least some of the plurality of actuators 330 may be disposed. The plurality of holes 310_h may be formed to extend through the front and rear surfaces (e.g., surfaces in the y-axis and -y-axis directions) of the base substrate 310_bd. The plurality of holes 310_h may be formed regularly, for example, according to a specific pattern. As an example, the substrate 310_bd may include a plurality of holes 310_h corresponding to the number of the plurality of actuators 330.

[0060] According to an embodiment, the structural substrate 310 may be formed such that multiple layers overlap each other. As an example, wires capable of supplying power to multiple actuators 330 may be disposed on at least one of the multiple layers of the structural substrate 310. For example, the structural substrate 310 may include a wire layer, support layers disposed on the front and rear surfaces of the wire layer, and at least one adhesive layer for bonding to the bottom surface of the housing recess 210_rc. Optionally, the structural substrate 310 may be configured as a single layer in which recesses for wires are formed. As an example, at least one of the multiple layers of the structural substrate 310 may include a board connection portion 311 that can be electrically connected to a printed circuit board 204 (or the first printed circuit board 1300 described later) of the electronic device 101. The board connection portion 311 may be configured to protrude from one side of the substrate 310_bd. For example, the board connection portion 311 may be configured to protrude from a point on the substrate 310_bd in the y-axis direction. The board connection portion 311 may be configured to protrude through a through-hole formed in the bottom of the first housing 210_bt toward the rearward direction (e.g., the surface viewed in the -z axis direction) of the bottom of the first housing 210_bt. At least one terminal 311_t (or electrode) may be provided on the board connection portion 311. The terminal 311_t may be electrically connected to a wire formed in the base substrate 310_bd of the structural substrate 310 and may be used to power a plurality of actuators 330 via the printed circuit board 204 (or the first printed circuit board 1300 described later).

[0061] According to an embodiment, the structural substrate 310 may be formed of a material having higher rigidity than the support structure 320. For example, at least a portion of the structural substrate 310 may be formed of a metallic material. Optionally, at least a portion of the structural substrate 310 may be formed of a reinforced plastic or polymer (e.g., polyethylene terephthalate (PET), polymethyl methacrylate (PMMA)) that provides rigidity equal to or greater than a certain level. Optionally, when the structural substrate 310 comprises multiple layers, the multiple layers may be formed of different materials. For example, one of the multiple layers of the structural substrate 310 facing the bottom surface of the housing recess 210_rc may include an adhesive layer. The adhesive layer may bond an area of ​​one surface of the structural substrate 310 from which the plurality of actuators 330 are not formed to the bottom surface of the housing recess 210_rc.

[0062] Reference Figures 2 to 6 as well as Figure 7The support structure 320 may be disposed on a first surface (e.g., the surface facing the y-axis direction) of the structural substrate 310. The support structure 320 and the structural substrate 310 may be spaced apart from each other. Optionally, an air gap may be formed between the support structure 320 and the structural substrate 310. The support structure 320 may move from the structural substrate 310 in the y-axis direction or the -y-axis direction in response to the operation of a plurality of actuators 330. As an example, the support structure 320 may move from the structural substrate 310 in the y-axis direction while the screen area of ​​the electronic device 101 is fixed (e.g., in a retracted position or an extended position) to contact (or approach the area at a predetermined first distance) a region of the display assembly 360 (e.g., a first extended region 263 of the display 260 in the retracted position or a second extended region 262 of the display 260 in the extended position). In this respect, at least a portion of the rear surface 320_bk of the support structure 320 facing the structural substrate 310 may be formed as flat (or entirely flat), and at least a portion of the front surface 320_fr of the support structure 320 facing the display assembly 360 may be formed as curved (or entirely recessed). Support recesses 320_sh, fastened to a plurality of actuators 330, may be provided on the rear surface 320_bk of the support structure 320. The support recesses 320_sh may include a number corresponding to the number of the plurality of actuators 330.

[0063] According to an embodiment, the support structure 320 may be formed of a material having lower rigidity (or higher (or greater) ductility or greater elasticity) than the structural substrate 310. For example, at least a portion of the support structure 320 may be formed of at least one of rubber, silicone, fibers (e.g., microfibers, quilts, wool, cotton, flannel, velvet, yarn), sponge structure, corduroy, or polymer materials. As an example, the support structure 320 may include multiple layers. Accordingly, at least some of the multiple layers of the support structure 320 may be formed of different materials. For example, the first layer of the support structure 320 facing the structural substrate 310 may be formed of a material having relatively higher rigidity than the other layers of the support structure 320 (e.g., plastic, reinforced plastic, plastic alloy, or polymer material having a rigidity equal to or greater than a certain level). The second layer of the support structure 320, located on top of the first layer, may be formed of a soft material (e.g., rubber, silicone, wool, or a polymeric material with lower (or less) ductility than the first layer) that prevents damage to the display assembly 360 when the support structure 320 comes into contact with the display assembly 360 due to external impact. Alternatively, the support structure 320 may be partially (or, depending on its location) formed of a different material.

[0064] As an example, the support structure 320 may include a central region 320_cen, an upper region 320_up, and a lower region 320_low. The upper region 320_up and the lower region 320_low may include regions that protrude further from the central region 320_cen in the y-axis direction relative to the rear surface 320_bk of the support structure 320. Optionally, the upper region 320_up and the lower region 320_low may include peripheral regions in the z-axis or -z-axis direction relative to the central region 320_cen. At least a portion of the upper region 320_up may include a region of the support structure 320 positioned near the upper end 210_sd4 of the first housing. At least a portion of the lower region 320_low may include a region of the support structure 320 positioned near the bottom 210_bt of the first housing.

[0065] According to an embodiment, a region of the recessed portion of the support structure 320 (e.g., the central region 320_cen) (e.g., the recessed centerline in the x-axis direction) may be formed of a first material (e.g., rubber or silicone resin), and at least some of the upper and lower peripheral regions relative to the central region 320_cen (e.g., the upper structural region 320_up and the lower structural region 320_low) may be formed of a second material different from the first material (e.g., wool or fiber). Optionally, at least a portion of the central region 320_cen and the lower structural region 320_low of the support structure 320 may be formed of the first material (e.g., a material that can achieve shock absorption (such as rubber or silicone resin)), and at least a portion of the upper structural region 320_up may be formed of a second material different from the first material (e.g., a material that can satisfy waterproof or dustproof purposes (such as wool or fiber material)). As another example, the central region 320_cen, the lower structural region 320_low, and the upper structural region 320_up may be formed of materials different from each other.

[0066] Reference Figures 2 to 8At least some of the plurality of actuators 330 may be disposed in a plurality of holes 310_h formed in the structural substrate 310 (e.g., the substrate 310_bd). Each of the plurality of actuators 330 may have a non-powered state (or a de-energized state) and a powered state (or an energized state). When powered (or when not powered), each of the plurality of actuators 330 may move at least a portion of the support structure 320 forward in a first surface direction of the structural substrate 310 (e.g., the y-axis direction or the direction facing the display assembly 360). When de-energized (or when powered in the opposite direction, or when de-energization is supplied), each of the plurality of actuators 330 may move at least a portion of the support structure 320 backward in a second surface direction of the structural substrate 310 (e.g., the -y-axis direction or the direction facing the bottom surface of the housing recess 210_rc). As an example, multiple actuators 330 may move the support structure 320 toward the display assembly 360, or may space the support structure 320 apart from the display assembly 360.

[0067] According to the embodiments, such as Figure 8 As shown, the actuator 330 may include a base 331 and a post 332. At least a portion of the base 331 may have a specific thickness and may include a hemispherical shape forming a space at its center. Optionally, the base 331 may include an umbrella shape surrounding a top, and the inner or outer side of the top may be partially formed flat. When powered from the outside (or when power is off), the base 331 may deform such that the projection direction of the top reverses. The post 332 may be disposed at the inner center of the base 331. As an example, the post 332 may include a cylindrical shape with a circular cross-section on one side. One end of the post 332 may be fixed (or adhered) to the inner side of the top of the base 331. The post 332 may be disposed perpendicular to the center of the top of the base 331. The length of the post 332 in the y-axis direction may be formed to be greater than the thickness of the base 331 in the y-axis direction. Therefore, multiple actuators 330 can pass through multiple holes 310_h formed in the base substrate 310_bd of the structural substrate 310 to be coupled (or adhered) to the rear surface 320_bk (or support recess 320_sh) of the support structure 320. The pillar 332 can maintain its shape or form regardless of the power supply.

As an example, Figure 9 State 901 is a diagram showing a portion of the front surface of the electronic device 101 when the electronic device 101 is in its first arrangement state, and Figure 9State 903 is an example diagram showing a cross-section of a portion of the electronic device 101 in state 901, taken along the cutting line A1-A1'.

[0069] Reference Figures 2 to 9 as well as Figure 9 As an example, in states 901 and 903, electronic device 101 may include a first housing 410, a second housing 420, a display assembly 360, a first outer casing 210, and a first-type auxiliary structure 300. Alternatively or additionally, electronic device 101 may also include the above-mentioned references. Figure 4 At least some of the components described.

[0070] According to an embodiment, the first arrangement state of the first type of auxiliary structure 300 may include a state in which the electronic device 101 is changed from a retracted position to an extended position, or a state in which the electronic device 101 is changed from an extended position to a retracted position. A user may indicate a position change by using at least one input device provided in the electronic device 101. The at least one input device may include at least one button disposed in the electronic device 101, a virtual key output via a screen user interface of the display 260 and indicating whether to retract or extend to the extended position, at least one sensor capable of sensing gestures corresponding to retracting or extending to the extended position, and at least one microphone capable of receiving voice input when retracting or extending to the extended position.

[0071] According to an embodiment, the first housing 210 may include a lower housing portion 210_sd3, a upper housing portion 210_sd4, and a bottom housing portion 210_bt. Alternatively, the first housing 210 may also include a right housing portion 210_sd1 and a left housing portion 210_sd2. According to an embodiment, a printed circuit board 204 (or at least one of the printed circuit board 204 and the first rear cover 441) may be disposed below the bottom housing portion 210_bt. The lower housing portion 210_sd3, the upper housing portion 210_sd4, and the bottom housing portion 210_bt may define a housing recess 210_rc. Optionally, the lower housing portion 210_sd3, the upper housing portion 210_sd4, the bottom housing portion 210_bt, a portion of the right housing portion 210_sd1, and a portion of the left housing portion 210_sd2 may define the housing recess 210_rc. At least a portion of the first type of auxiliary structure 300 may be disposed (or fixed) in the housing recess 210_rc. In this regard, a structural arrangement recess 210_sh, in which at least a portion of the first type of auxiliary structure 300 is disposed, may be formed on the inner surface of the housing recess 210_rc (or the inner surface of the lower end of the first housing 210_sd3). The structural arrangement recess 210_sh may be formed such that at least a portion of the structural arrangement recess 210_sh is recessed from the inner surface of the housing recess 210_rc (or the bottom of the inner surface of the lower end of the first housing 210_sd3) in the -y-axis direction. The structural arrangement recess 210_sh may include a shape corresponding to the rear surface of the first type of auxiliary structure 300 (or at least a portion therein of the bases 331 of a plurality of actuators 330 on the rear surface of the structural substrate 310, arranged in a specific pattern). As an example, at least a portion of the structural arrangement recess 210_sh may include a groove in which the bases 331 of a plurality of actuators 330 are disposed. As an example, at least a portion of the structural arrangement recess 210_sh may include a number of grooves corresponding to the number of the plurality of actuators 330.

[0072] As described above, the first type of auxiliary structure 300 may include a structural substrate 310, a support structure 320, and a plurality of actuators 330. At least a portion of the structural substrate 310 may be fixed or adhered to the inner surface of the lower end 210_sd3 of the first housing. In this respect, the electronic device 101 may also include an adhesive layer 310_ad between the inner surface of the lower end 210_sd3 of the first housing and a surface of the structural substrate 310 (e.g., the surface facing the -y-axis direction). As another example, the adhesive layer 310_ad may be included in the first type of auxiliary structure 300. At least some of the plurality of actuators 330 may be disposed in a plurality of holes (e.g., through the front and rear surfaces of the structural substrate 310) formed. Figure 6In 310_h). As an example, when the first type of auxiliary structure 300 is in the first arrangement state, the base 331 may be set (or formed) to protrude toward the rear surface (e.g., the surface viewed from the -y axis direction) of the structural substrate 310, and a portion of the pillar 332 is located in a plurality of holes ( Figure 6 The remaining portion of the pillar 332 may be configured to protrude from the front surface of the structural substrate 310 (e.g., the surface viewed from the y-axis direction or the surface facing the direction in which the support structure 320 is provided). As an example, the remaining portion of the pillar 332 may be inserted into and fixed to the support recess 320_sh formed in the support structure 320.

[0073] According to an embodiment, the support structure 320 may include a shape recessed in the -y-axis direction. In this regard, at least a portion of the support structure 320 may include a curved surface. As an example, the curvature of the curved surface of the support structure 320 (e.g., the surface facing the display assembly 360) may be formed to be the same as or similar to the curvature of the display assembly 360 (or the curvature of the curved region of the display). Optionally, the curvature of the curved surface of the support structure 320 may be formed to be the same as or similar to the curvature of the curved region 421 of the second housing 420 within a certain error range. Optionally, the curvature of the curved surface of the support structure 320 may be the same as or similar to the curvature of the first extended region 263 in the retracted position.

[0074] According to an embodiment, the display assembly 360 may include a display 260 and a multi-bar assembly 260a. The display 260 may include a first screen region 261, a first extension region 263, and a second extension region 262. As an example, the display curved region 260_cr may include at least a portion of the first extension region 263 and the second extension region 262. As an example, the display curved region 260_cr may include the first extension region 263 in a state immediately preceding a change from a retracted position to an extended position (or in the retracted position state). When at least a portion of the first extension region 263 moves to the front surface (e.g., in the z-axis direction) after the retracted position, the display curved region 260_cr may include a portion of the first extension region 263 and at least a portion of the second extension region 262. Optionally, in the fully extended position state, the display curved region 260_cr may include at least a portion of the second extension region 262. The multi-bar assembly 260a may include a plurality of multi-bars, a support member supporting the plurality of multi-bars, and an adhesive layer disposed between the support member and the plurality of multi-bars.

[0075] According to an embodiment, in a first arrangement state where the retracted position is changed to an extended position (or the extended position is changed to a retracted position), a gap of a predetermined first size can be formed between the support structure 320 and the display bending region 260_cr. Because the gap of the predetermined first size provides a non-contact state between a portion of the display assembly 360 (e.g., a portion of the display assembly 360 located on the bending region 421 of the second housing 420) and the first type of auxiliary structure 300, damage or deformation of the display assembly 360 (or the display 260) due to the first type of auxiliary structure 300 can be prevented (or reduced). Additionally or optionally, the first type of auxiliary structure 300 can prevent foreign objects from being introduced into the housing recess 210_rc.

[0076] Figure 10 This is a view showing a second arrangement state of an electronic device according to an embodiment of the present disclosure. As an example, Figure 10 State 1001 is a diagram showing a portion of the front surface of the electronic device 101 when the electronic device 101 is in the second arrangement state, and Figure 10 State 1003 is an example diagram showing a cross-section of a portion of the electronic device 101 in state 1001, taken along the cutting line A2-A2'.

[0077] Reference Figures 2 to 10 as well as Figure 10 As an example, in states 1001 and 1003, electronic device 101 may include a first housing 410, a second housing 420, a display assembly 360, a first outer casing 210, and a first type of auxiliary structure 300. Alternatively or additionally, electronic device 101 may also include the above-mentioned references. Figure 4 At least some of the components described. As an example, the first type of auxiliary structure 300 may include a structural substrate 310, a support structure 320, and a plurality of actuators 330, and may also include an adhesive layer 310_ad disposed between at least a portion of the structural substrate 310 and the inner side of the housing recess 210_rc. The housing recess 210_rc of the first housing 210 may include a structural arrangement recess 210_sh in which at least a portion of the first type of auxiliary structure 300 is disposed. The structural arrangement recess 210_sh may be configured (or formed) such that at least a portion of the base 331 of the plurality of actuators 330 may be disposed in the structural arrangement recess 210_sh.

[0078] According to an embodiment, in a second arrangement state of the first type of auxiliary structure 300, the electronic device 101 may include a retracted position state or an extended position state. Optionally, according to an embodiment, Figure 10The second arrangement state may include an intermediate state in which the display assembly 360 is temporarily fixed. The accompanying drawing is a view illustrating an example of the retracted position state. In the extended position, the second extension region 262 may be partially positioned above the reference. Figure 9 In the described display curved region 260_cr, or at least a portion of the first extension region 263 and the second extension region 262, it can be configured to face the front surface (z-axis direction) together with the first screen region 261.

[0079] In the second arrangement, the bases 331 of the plurality of actuators 330 can protrude in the y-axis direction by power supply (or power de-energization). Optionally, the bases 331 of the plurality of actuators 330 can be configured (or formed or deformed) to protrude in the y-axis direction. Accordingly, the post 332 protruding from the center of the base 331 in the y-axis direction can be configured to protrude further in the y-axis direction than in the previous state. As the post 332 moves, the support structure 320 connected to the post 332 can move relative to the structural substrate 310 in the y-axis direction. As an example, the position of the support structure 320 can be changed in the housing recess 210_rc. As an example, a gap having a second size smaller than the previously formed gap having a first size can be formed between a surface of the support structure 320 (e.g., the surface facing the y-axis direction) and a portion of the display assembly 360 (e.g., the first extension region 263). Optionally, a surface of the support structure 320 (e.g., the surface facing the y-axis direction) and a portion of the display assembly 360 can be formed to contact each other. According to an embodiment, considering that the retracted or extended position state is maintained for a longer period than the changed state (e.g., the retracted position is changed to the extended position or the extended position is changed to the retracted position), the plurality of actuators 330 can remain in a state without power supply. Figure 10 The second arrangement state described herein, and can be maintained during power supply. Figure 9 The first arrangement state is described in the document. However, this disclosure is not limited to this and can be configured in the opposite manner.

[0080] Because the support structure 320 of the first type of auxiliary structure 300 remains in contact with a portion of the display assembly 360, damage to a portion of the display assembly 360 can be prevented when an external impact is applied. Furthermore, while the support structure 320 of the first type of auxiliary structure 300 remains in contact with a portion of the display assembly 360, foreign objects can be prevented from being introduced through the gap between the upper end 210_sd4 of the first housing and the display assembly 360 by blocking the space (or gap) between them.

[0081] Figure 11 This is a view illustrating an example of a second type of auxiliary structure according to an embodiment of the present disclosure. Figure 11 In the first arrangement, state 1101 is a view showing a modified form of the second type auxiliary structure 300a (or structure, second type structure) in the first arrangement state, and state 1103 is a view showing a modified form of the second type auxiliary structure 300a in the second arrangement state.

[0082] Reference Figures 2 to 11 The second type of auxiliary structure 300a may include a structural substrate 310, a first support structure 321a, a second support structure 321b, and a plurality of actuators 330. The structural substrate 310 may have the same characteristics as described above. Figures 4 to 10 The structural substrate 310 described has the same structure. As an example, the structural substrate 310 may include a base substrate 310_bd and a plate connection portion 311. Wires connecting to a plurality of actuators 330 may be disposed in the base substrate 310_bd, and at least one terminal may be disposed in the plate connection portion 311. At least some of the plurality of actuators 330 are disposed in a plurality of holes therein (e.g., Figure 6 Holes 310_h can be formed in the substrate 310_bd.

[0083] The first support structure 321a may include a flat first surface (e.g., a surface facing the structural substrate 310 (e.g., a surface facing the y-axis direction)) and a second surface having a specific inclination or partial curvature (e.g., a surface opposite to the first surface). The post portion 332 of the actuator 330 is inserted into at least one of the first support recesses therein (e.g., as shown above). Figure 9 The described support recess 320_sh may be formed at least a portion of the first surface of the first support structure 321a. The first support structure 321a may include a structure in which the width of the z-axis cross-section of the first support structure 321a increases from the -z-axis direction toward the z-axis direction. As an example, the width of the z-axis periphery of the z-axis cross-section of the first support structure 321a may be larger than the width of the z-axis periphery. The inclination or curvature (or curvature) of the second surface of the first support structure 321a may be related to the display curvature region of the display assembly 360 (e.g., Figure 9 The tilt or curvature of a portion of the curved surface (e.g., a curved surface facing the z-axis or diagonal direction) of the curved area 260_cr of the display corresponds accordingly.

[0084] The second support structure 321b may be configured to be spaced apart from the first support structure 321a by a specific interval in the upward / downward direction (or the z-axis direction, or the -z-axis direction). The shape, size, and position of the second support structure 321b may have at least one of the following: a shape, size, and position symmetrical about the first support structure 321a based on an imaginary lateral centerline of the structural substrate 310 (e.g., an imaginary lateral centerline 1100_L parallel to the -x-axis or x-axis and passing between the first support structure 321a and the second support structure 321b). As an example, the second support structure 321b may include a surface facing the structural substrate 310 and formed as flat, and a surface facing the display assembly 360 when mounted in the electronic device 101 and having a specific tilt or specific curvature (e.g., with...). Figure 9 The other surface of the curved region 260_cr of the display has the same or similar curvature. The post portion 332 of the actuator 330 is inserted into at least one of the second support recesses therein (e.g., as shown above). Figure 9 The described support recess 320_sh can be formed on one surface of the second support structure 321b.

[0085] The plurality of actuators 330 may include a first actuator group disposed in a first row (e.g., a row formed offset in the z-axis direction relative to the lateral centerline 1100_L of the structural substrate 310, in which the plurality of actuators are arranged in the x-axis direction) and coupled to a first support structure 321a, and a second actuator group disposed in a second row (e.g., a row arranged parallel to the first row, a row formed offset in the -z-axis direction relative to the lateral centerline 1100_L of the structural substrate 310, in which the plurality of actuators are arranged in the x-axis direction) and coupled to a second support structure 321b. In the first arrangement state, the bases 331 of the plurality of actuators 330 may be arranged relative to the structural substrate 310 in the -y-axis direction (or in the first surface direction of the structural substrate 310 facing the bottom surface of the housing recess 210_rc). Some of the pillars 332 of the plurality of actuators 330 may be located in the -y-axis direction relative to the structural substrate 310, some of the pillars 332 may be located in holes formed in the structural substrate 310, and the remaining pillars 332 may be located in the y-axis direction relative to the structural substrate 310. Accordingly, a gap having a first size may be formed between the structural substrate 310 and the first support structure 321a (or between the structural substrate 310 and the second support structure 321b). In the second arrangement, the bases 331 of the plurality of actuators 330 may be disposed in the y-axis direction (or in the direction facing the display assembly 360) relative to the structural substrate 310. The pillars 332 of the plurality of actuators 330 may be located in the y-axis direction relative to the structural substrate 310. Accordingly, a gap having a second size larger than the first size may be formed between the structural substrate 310 and the first support structure 321a (or between the structural substrate 310 and the second support structure 321b). According to an embodiment, when the second type of auxiliary structure 300a is installed in the electronic device 101, at least a portion of the first support structure 321a and the second support structure 321b can contact a surface of the display assembly 360 in the second arrangement state.

[0086] In addition, Figure 11 The diagram illustrates two forms of support structures 321a and 321b disposed on the structural substrate 310, but this disclosure is not limited thereto. As an example, the electronic device 101 may include an auxiliary structure in which multiple first support structures 321a are disposed at specific intervals in a first row of the structural substrate 310 in the -x-axis direction or the x-axis direction, and multiple second support structures 321b are disposed at specific intervals in a second row. Optionally, the electronic device 101 may include an auxiliary structure having the same shape as the first support structure 321a (whose z-axis cross-sectional shape is shown) and a length equal to the length of the structural substrate 310 in the x-axis direction (or as shown above). Figure 7A first modified support structure (at least a portion of the length of the described support structure 320 in the x-axis direction) is disposed in a first row of the structural substrate 310, and a second modified support structure having the same shape as the first modified support structure but with the opposite orientation of the curved surface arrangement is disposed in a second row. As another example, the first modified support structure (or second modified support structure) may include, for example, a series of first support structures 321a (or second support structures 321b) of specific dimensions connected continuously. Optionally, the electronic device 101 may include a plurality of first support structures 321a and at least one first modified support structure, and a plurality of second support structures 321b and at least one second modified support structure. According to an embodiment, a specific auxiliary structure disposed in the electronic device 101 may include support structures, each having a first surface facing the structural substrate and having a rectangular shape (e.g., a square) of specific dimensions and being configured as a plurality of individual units, and may include a structure in which the support structures are arranged in a grid on one or more structural substrates. As an example, referring to the above... Figure 5 Compared to the described auxiliary structures, structures with relatively small dimensions can be aggregated to form an auxiliary structure, each auxiliary structure comprising elements having the same dimensions as those referenced above. Figure 8 The description includes a structural substrate and support structure of a specific size corresponding to the dimensions of an actuator. According to an embodiment, the above references... Figure 8 The dimensions of an actuator described may vary depending on at least one of the dimensions, type, and arrangement of the support structure.

[0087] Figure 12 This is a view illustrating an example of an electronic device including a third type of auxiliary structure according to an embodiment of the present disclosure.

[0088] Reference Figures 2 to 12 The electronic device 101 may include a display assembly 360, a second housing 420, a first housing 210, a third type auxiliary structure 300b1 (or structure, third type structure), and a fourth type auxiliary structure 300b2 (or structure, fourth type structure). Alternatively or optionally, as referred to above... Figure 4 In addition to the components described above, the electronic device 101 may also include at least some other components.

[0089] The view shown in the accompanying drawings corresponds to an example of a first arrangement, in which the third type auxiliary structure 300b1 and the fourth type auxiliary structure 300b2 are spaced apart from the display assembly 360, such that the electronic device 101 is deformed from a retracted position to an extended position. When the electronic device 101 is in a second arrangement corresponding to either the retracted or extended position, at least a portion of the third type auxiliary structure 300b1 and the fourth type auxiliary structure 300b2 may be formed to contact (or be close to) at least a portion of the display assembly 360.

[0090] The third type of auxiliary structure 300b1 may include a first structural substrate 310a1, a third support structure 322a, and a first actuator 330g1 (or a first actuator group).

[0091] The width of the first structural substrate 310a1 may have, for example, as shown above. Figure 6 The width (or z-axis length) of the described structural substrate 310 is half of its dimension. Optionally, the length of the first structural substrate 310a1 in the x-axis direction can be formed as described above. Figure 6 The structural substrates 310 described herein have the same or similar lengths in the x-axis direction, and the length of the first structural substrate 310a1 in the z-axis direction may be formed to be greater than that described above. Figure 6 The described structural substrate 310 has a small length in the z-axis direction. The first structural substrate 310a1 may have a size in which, for example, one first actuator 330g1 can be set. Alternatively, the first structural substrate 310a1 may have a size in which multiple first actuators 330g1 (e.g., multiple actuators are configured to form a first actuator group in a row) can be set.

[0092] The third support structure 322a may have the same characteristics as the one mentioned above. Figure 11 The second support structure 321b described has at least one size and shape that is the same as or similar to at least one of the sizes and shapes. The third support structure 322a may have a curved surface (or curvature) (e.g., a shape that is at least partially recessed in the z-axis direction) corresponding to a portion of the first extension region 263 of the display assembly 360 (e.g., a portion that forms a specific curvature and at least a portion of which protrudes in the z-axis direction).

[0093] The first actuator 330g1 may have the same characteristics as the above reference. Figure 8The actuator 330 described has the same structure. According to an embodiment, in a first arrangement state, the first actuator 330g1 can be configured such that the base 331 is located on a surface (e.g., a surface in the -y-axis direction or a surface in the diagonal direction between the -z and y axes) relative to the first structural substrate 310a1, a portion of the pillar 332 is located inside the base 331, and the remaining portion protrudes a first length relative to the holes in the structural substrate 310 and the first structural substrate 310a1 towards the opposing surface (e.g., in the y-axis direction or in the diagonal direction between the -z and y axes). The first actuator 330g1 can respond to the processor of the electronic device 101 (e.g., ...). Figure 1 Under the control of the processor 120, it is transformed into a second arrangement state. In the second arrangement state, the base 331 of the first actuator 330g1 may have a state in which the base 331 protrudes relative to the first structural substrate 310a1 to the opposing surface (e.g., in the y-axis direction or the diagonal direction between the -z axis and the y axis), and the column portion 332 may protrude from a point of the base 331 toward the opposing surface by a second length longer than the first length. In the second arrangement state, the third support structure 322a of the third type auxiliary structure 300b1 may contact (or be within a pre-designed specific distance) a specific portion of the display assembly 360 (e.g., the upper end of the first extension region 263 (or a portion in the z-axis direction) or a portion of the first extension region 263 that is positioned close to the first screen region 261).

[0094] The aforementioned third type auxiliary structure 300b1 can be disposed in a first structural arrangement recess 210_h1 formed between the lower end 210_sd3 and the upper end 210_sd4 of the first housing. The electronic device 101 may also include a fixing device such that the third type auxiliary structure 300b1 is fixed to the first structural arrangement recess 210_h1. The first structural arrangement recess 210_h1 may include, for example, a shape with an opening in the diagonal direction between the -z axis and the y axis. The accompanying drawings show an example of a cross-section of one side of the first housing 210, and the first structural substrate 310a1 of the third type auxiliary structure 300b1 can be manufactured in the form of a module having a substrate shape, wherein the substrate shape has dimensions similar to those of the first actuator 330g1. When the third type auxiliary structure 300b1 comprises multiple modules, the third type auxiliary structures 300b1 can be disposed within the first housing 210 and spaced apart from each other at specific intervals. In this respect, the first structural arrangement recess 210_h1 may include a plurality of recesses disposed inside the first housing 210 and spaced apart from each other at a specific interval. The wires electrically connecting the third type auxiliary structure 300b1 may be disposed inside the first housing 210 of the electronic device 101 (e.g., in...). Figure 5(On the bottom surface of the outer shell groove 210_rc). Optionally, the first structural substrate 310a1 may have the same as the one referenced above. Figure 6 The described structural substrate 310 has the same or similar x-axis length, and the z-axis length of the first structural substrate 310a1 can be formed to have a length greater than that of the referenced above. Figure 6 The described structural substrate 310 has a small z-axis length (e.g., half the size of the structural substrate 310). In this case, the wires connecting the third type auxiliary structure 300b1 can be included on (or inside) the first structural substrate 310a1. When the first structural substrate 310a1 is formed as a substrate having a length corresponding to the x-axis length of the lower end 210_sd3 of the first housing, the first structural arrangement recess 210_h1 can include a recess inside the lower end 210_sd3 of the first housing, into which the first structural substrate 310a1 can be inserted.

[0095] The fourth type of auxiliary structure 300b2 may include a second structural substrate 310a2, a fourth support structure 322b, and a second actuator 330g2 (or a second actuator group). The fourth type of auxiliary structure 300b2 has the same or similar structure as the third type of auxiliary structure 300b1, and the arrangement position of the fourth type of auxiliary structure 300b2 may be symmetrical to that of the third type of auxiliary structure 300b1. As an example, the fourth support structure 322b of the fourth type of auxiliary structure 300b2 may be configured to face the diagonal direction between the z-axis and the y-axis. At least a portion of the fourth support structure 322b may be disposed in the second structural arrangement recess 210_h2 in the first arrangement state, and in the second arrangement state, it may be configured to contact (or be close to) another portion of the display assembly 360 (e.g., the lower end of the first extension region 263 or a portion of the first extension region 263 disposed near the second extension region 262).

[0096] As another example, the third type auxiliary structure 300b1 and the fourth type auxiliary structure 300b2 may include different structures. For example, the third type auxiliary structure 300b1 may include a first number of third support structures 322a and a first number of first structural substrates 310a1 having a length of a first dimension in the x-axis direction, and the fourth type auxiliary structure 300b2 may include a second number of fourth support structures 322b and a second number of second structural substrates 310a2 having a length smaller than the first dimension and a greater than the first number in the x-axis direction. Optionally, the third type auxiliary structure 300b1 may include multiple individual modules disposed in the housing recess 210_rc, and the fourth type auxiliary structure 300b2 may include a structure in which a support structure is formed on a structural substrate.

[0097] Figure 13 This is a view illustrating an example of an electronic device including a fifth type of auxiliary structure according to an embodiment of the present disclosure.

[0098] Reference Figures 2 to 13 The electronic device 101 according to an embodiment may include a display assembly 360, a second housing 420, a first housing 210, and a fifth type auxiliary structure 300c (or structure, fifth type structure). Additionally or optionally, the electronic device 101 may also include a third type auxiliary structure 300b1 (or a fourth type auxiliary structure 300b2). For example, although... Figure 13 An electronic device 101 is shown that includes both a third type auxiliary structure 300b1 and a fifth type auxiliary structure 300c, but the electronic device 101 may include only the fifth type auxiliary structure 300c. The third type auxiliary structure 300b1 and the first structural arrangement recess 210_h1 may include features similar to those described above. Figure 12 The third type of auxiliary structure described herein has the same or similar shape as the recess in the first structure.

[0099] The fifth type of auxiliary structure 300c may include a third structural substrate 310a3, a fifth support structure 322c, and a third actuator 330g3 (or a first actuator group).

[0100] For example, the third structural substrate 310a3 may have a structure that is more advanced than the one described above. Figure 6 The structure substrate 310 described above is smaller in size and larger than the one described above. Figure 12 The first structural substrate 310a1 described herein has a larger dimension. As an example, the third structural substrate 310a3 may be formed to have a dimension that is half or greater than the z-axis height of the recessed portion of the first housing 210. Optionally, the third structural substrate 310a3 may be formed to have a z-axis length corresponding to a height that is half or greater than the z-axis height of the display assembly 360. A plurality of fifth-type auxiliary structures 300c may be disposed inside the first housing 210, or may form a single structure. Accordingly, the third structural substrate 310a3 may include a single substrate disposed inside the first housing 210, or may include a plurality of substrates spaced apart from each other at specific intervals. The third structural substrate 310a3 may include wires for supplying power to the third actuator 330g3 and holes for providing the third actuator 330g3.

[0101] The fifth support structure 322c can be formed to have a greater than the one above. Figure 7 The support structure 320 described above has a smaller z-axis length than the one described above. Figure 11 The z-axis length of the first support structure 321a described in the text or on the top Figure 12The third support structure 322a described herein has a larger z-axis length. As an example, the dimension of one surface of the fifth support structure 322c in the -y-axis direction may be the same as or similar to the dimension of one surface of the third structure substrate 310a3 within a certain tolerance range. According to an embodiment, the z-axis height of the fifth support structure 322c may be formed to be half or more of the z-axis height of the recessed portion having the first housing 210. Alternatively, the z-axis height of the fifth support structure 322c may be formed to be half or more of the z-axis height of the display assembly 360.

[0102] The third actuator 330g3 may have the same characteristics as the one mentioned above. Figure 11 or Figure 12 The actuator described herein has the same dimensions and structure. Optionally, the third actuator 330g3 may include actuators with dimensions larger than those described above. Figure 11 or Figure 12 The actuator described herein has a large base portion 331a and a large post portion 332a. The post portion 332a can be inserted into a support recess 320_sh formed on the rear surface of the fifth support structure 322c. The support recess 320_sh can be formed at the center of gravity of the rear surface of the fifth support structure 322c. As an example, the size of the actuator can vary depending on at least one of the size, position, and orientation of the support structure.

[0103] According to an embodiment, in a first arrangement state, at least a portion of the fifth support structure 322c may be disposed in the third structural arrangement recess 210_h3 and define a first-sized gap with a surface of the third structural substrate 310a3. In a second arrangement state, at least a portion of the fifth support structure 322c may protrude from the third structural arrangement recess 210_h3 in the y-axis direction and define a second-sized gap with a surface of the third structural substrate 310a3 that is larger than the first size. Optionally, in the second arrangement state, at least a portion of the fifth support structure 322c may contact a portion of the display assembly 360 (e.g., the first extension region 263), or may have a state of proximity within a predetermined specific distance. The fifth type auxiliary structure 300c may be linearly movable in a direction parallel to the bottom 210_bt of the first housing 210. In this respect, the third structural arrangement recess 210_h3 may be formed as being etched inside the first housing 210 in the -y-axis direction. In the second arrangement and retracted position, the fifth support structure 322c can be configured to support half or more of the first extended region 263 (or the curved region of the display) of the display assembly 360, thereby preventing damage to the display assembly 360 in the event of an external impact. In the second arrangement and extended position, the fifth support structure 322c can support half or more of the second extended region 262 (or the curved region of the display corresponding to the curved region 421 of the second housing 420), thereby preventing damage to the display assembly 360. The electronic device 101 can support an intermediate state between the maximum retracted position and the maximum extended position. Accordingly, when the electronic device 101 is temporarily fixed in the intermediate state, the fifth support structure 322c can contact a specific area of ​​the display assembly 360 (e.g., the curved region of the display corresponding to the intermediate state), thereby preventing damage to that specific area of ​​the display assembly 360.

[0104] Furthermore, in the above structure, although the third type auxiliary structure 300b1 is disposed between the lower end 210_sd3 and the upper end 210_sd4 of the first housing, and the fifth type auxiliary structure 300c is disposed on one side of the lower end 210_sd3 of the first housing, this disclosure is not limited thereto. For example, the fifth type auxiliary structure 300c may be disposed at a position offset from the lower end 210_sd3 of the first housing toward the upper end 210_sd4 of the first housing. In this case, the fifth type auxiliary structure 300c may include a fifth support structure disposed in a direction opposite to the direction of the curved region arrangement of the fifth support structure 322c of the currently shown fifth type auxiliary structure 300c. For example, the fifth type auxiliary structure 300c may be disposed at a position symmetrical to each other above and below (or from the z-axis to the -z-axis) with respect to the imaginary lateral centerline cen_line of the display assembly 360. Accordingly, at least a portion of the fifth support structure 322c may be positioned close to the upper end 210_sd4 of the first housing, and in the second arrangement state, the fifth support structure 322c may block the gap between the upper end 210_sd4 of the first housing and the display assembly 360.

[0105] The accompanying drawings show an example of a cross-section of one side of the first housing 210, and the third structural substrate 310a3 of the fifth type auxiliary structure 300c can be manufactured in the form of a module having a substrate shape, wherein the substrate shape has dimensions similar to those of the third actuator 330g3. The fifth type auxiliary structure 300c may include multiple modules, and correspondingly, the third structural arrangement recess 210_h3 may include multiple recesses spaced apart from each other at specific intervals and disposed inside the first housing 210. Wires electrically connecting the fifth type auxiliary structure 300c may be disposed inside the first housing 210 of the electronic device 101 (e.g., in...). Figure 5 (On the bottom surface of the housing recess 210_rc). Optionally, the fifth type auxiliary structure 300c may include a third structural substrate 310a3 having a length corresponding to the x-axis length of the lower end 210_sd3 of the first housing, and may include a plurality of third actuators 330g3 and a fifth support structure 322c.

[0106] In addition, although the above are in Figures 2 to 13 The examples of auxiliary structures described herein each have independent structures and can be applied to electronic device 101, but this disclosure is not limited thereto. For example, Figures 2 to 10 At least some features of the auxiliary structure (e.g., 300) described herein can be selectively applied. Figures 11 to 13 At least some of the auxiliary structures 300a, 300b1, 300b2, and 300c described herein. Optionally, Figures 11 to 13The various forms of auxiliary structures 300a, 300b1, 300b2, and 300c described herein can be combined with each other. For example, at least one of the auxiliary structures 300a, 300b1, 300b2, and 300c of this disclosure may include a structure in which an actuator is disposed as a separate module on a structural substrate, or may include a structure in which multiple actuators are disposed on a structural substrate. Furthermore, the support structures included in the auxiliary structures 300a, 300b1, 300b2, and 300c of this disclosure may be provided separately in a form corresponding to the size of an actuator, or may be provided in a form having a single body supporting multiple actuators. As an example, the support structure may be provided in a grid form divided in the longitudinal and transverse directions, and the grid form applicable to an electronic device 101 may include at least one type. For example, support structures with different grid forms (e.g., Figures 11 to 13 At least one of the support structures described herein may be applied to an electronic device 101.

[0107] Figure 14 This is a view illustrating an example of a first printed circuit board connected to an auxiliary structure according to an embodiment of the present disclosure. Figure 14 In the diagram, state 1401 corresponds to an example showing the first printed circuit board 1300 and the first housing 210 separated, and state 1403 corresponds to an example showing the first printed circuit board 1300 disposed on the rear surface of the first housing 210 (e.g., the rear surface of the bottom 210_bt of the first housing). State 1405 corresponds to an example showing a portion of the first printed circuit board 1300 disposed on the first housing 210, and state 1407 corresponds to an example showing a cross-section taken along cutting line A3-A3' in state 1405. Figure 14 The diagram illustrates a structure using the first type of auxiliary structure 300; however, this disclosure is not limited thereto. For example, this can also be applied to the structures described above. Figures 11 to 13 Other types of auxiliary structures described in the text, in this respect, Figures 11 to 13 At least one of the structural substrates described herein may include a structure corresponding to the board connection portion 311.

[0108] Reference Figures 2 to 14The first housing 210 may include a first housing bottom 210_bt, a first housing right portion 210_sd1, a first housing left portion 210_sd2, a first housing lower end 210_sd3, and a first housing upper end 210_sd4. The first printed circuit board 1300 may include, for example, a first PCB portion 1300a whose length in a first direction (e.g., the y-axis direction) is longer than its length in a second direction (e.g., the x-axis direction); and a second PCB portion 1300b connected to the first PCB portion 1300a and whose length in the second direction is longer than its length in the first direction. PCB terminals 1300e, which can be electrically connected to the first type auxiliary structure 300, may be provided at a portion of the second PCB portion 1300b. For example, PCB terminals 1300e may be provided on a surface of the second PCB portion 1300b facing the front surface of the first housing bottom 210_bt, and may be provided at a position facing the board connection portion 311 of the first type auxiliary structure 300. In the accompanying drawings, although PCB terminal 1300e is shown as having two terminals arranged in the form of a C-clamp, embodiments of this disclosure are not limited to the number or form of PCB terminals 1300e. Referring to a cross-section taken along the cutting line A3-A3' of state 1405, the first type of auxiliary structure 300 includes a structural substrate 310 and a support structure 320, and referring to the above... Figures 2 to 13 The auxiliary structure described herein, the first type of auxiliary structure 300 may include at least one actuator. Additionally, the first type of auxiliary structure 300 may also include a fixing device 310_ad (e.g., coupling member, adhesive member, adhesive layer) for fixing the structural substrate 310 to the lower end 210_sd3 of the first housing.

[0109] The first printed circuit board 1300 may be held (or attached, fixed, or disposed) on the rear surface (e.g., the surface viewed in the -z-axis direction) of the first housing bottom 210_bt. At least a portion of the first housing bottom 210_bt may include at least one hole (e.g., 210_bth) through the front and rear surfaces (e.g., the surfaces in the z-axis or -z-axis direction), and through at least one hole (e.g., 210_bth), at least a portion of the first printed circuit board 1300 may be disposed on the front surface (the surface viewed in the z-axis direction) of the first housing bottom 210_bt. As an example, through the hole 210_bth formed in the first housing bottom 210_bt, a portion of the first printed circuit board 1300 may be exposed on the front surface of the first housing bottom 210_bt, and the exposed portion of the first printed circuit board 1300 may be in electrical contact with a portion of the second printed circuit board 1500. Similarly, through the holes formed in the bottom 210_bt of the first housing, at least a portion of the board connection portion 311 of the first type of auxiliary structure 300 can be exposed toward the rear surface (e.g., the surface facing the -z axis direction) of the bottom 210_bt of the first housing. PCB terminals 1300e can be electrically connected to terminals 311_t formed at the board connection portion 311 of the first type of auxiliary structure 300. The terminals 311_t formed at the board connection portion 311 can be formed to have the same or similar number as the terminals formed at the PCB terminals 1300e.

[0110] The first printed circuit board 1300 can be obtained from a battery (e.g., Figure 4 The battery 205 receives power and can transmit the supplied power to the terminal 311_t of the board connection portion 311 via the PCB terminal 1300e. The power transmitted through the terminal 311_t of the board connection portion 311 can be supplied to multiple actuators (e.g., [missing information]) via wires provided on the structural substrate 310. Figure 5Multiple actuators 330). When powered on, the first type of auxiliary structure 300 can move the support structure 320 in a first direction to adjust the gap between the support structure 320 and the structural substrate 310 to a first size, and when powered off, the first type of auxiliary structure 300 can move the support structure 320 in a second direction opposite to the first direction to adjust the gap between the structural substrate 310 and the support structure 320 to a second size smaller (or larger) than the first size. The size of the gap formed between the support structure 320 and the structural substrate 310 can vary according to the design in the powered or powered-off state. As an example, when powered off, the gap between the support structure 320 and the structural substrate 310 can become the first size (or the minimum size that the first type of auxiliary structure 300 can form), and when powered on, the gap between the support structure 320 and the structural substrate 310 can become the second size (or the maximum size that the first type of auxiliary structure 300 can form). Optionally, when powered off, the display assembly of the electronic device 101 (e.g., Figure 4 The gap between the display assembly 360 and the support structure 320 can be changed to a second size (or the maximum size that the first type of auxiliary structure 300 can form), and when powered, the display assembly (e.g., Figure 4 The gap between the display assembly 360 and the support structure 320 can be changed to a first size (or the minimum size that the first type of auxiliary structure 300 can form or a state where the gap is 0, i.e., a contact state).

[0111] Figure 15 This is a view illustrating an example of the connection relationship between a first printed circuit board and other printed circuit boards according to an embodiment of the present disclosure. Figure 15 In the above, state 1501 shows an example of a form in which the first housing 210, the first shell 410, and the second shell 420 are separated, and state 1503 shows an example of a form in which the first housing 210, the first shell 410, and the second shell 420 are coupled to each other.

[0112] Reference Figures 2 to 15The electronic device 101 may include a first housing 210, a first shell 410, a second shell 420, a first printed circuit board 1300, a second printed circuit board 1500, and a third printed circuit board 1400. The second shell 420 may be located on the rear surface of the first shell 410, and the first shell 210 may be configured to cover at least a portion of the second shell 420. The first shell 210 and the second shell 420 may be linearly movable in a first direction or a second direction (e.g., the -y-axis direction or the y-axis direction), and correspondingly, the first shell 210 may be linearly movable in the first direction or the second direction. Depending on the observation point, the first shell 210 and the second shell 420 may be fixed, and the first shell 410 may be linearly movable in the second direction or the first direction (e.g., the y-axis direction or the -y-axis direction).

[0113] As shown above (refer to the reference) Figure 14 At least a portion of the first printed circuit board 1300, which is connected to an auxiliary structure (e.g., a first type of auxiliary structure 300), may be disposed on the rear surface (e.g., the surface viewed from the -z-axis direction) of the first housing 210. The first housing 210 may include at least one hole for connecting at least a portion of the first printed circuit board 1300 to other structures. For example, the first type of auxiliary structure 300 may be disposed in the first housing 210, and the board connection portion 311 of the structural substrate 310 of the first type of auxiliary structure 300 may be electrically connected to the PCB terminal 1300e of the first printed circuit board 1300. The end of the first printed circuit board 1300 extending in the y-axis direction may include a connection structure that can be connected to a second printed circuit board 1500. For example, one periphery of the first printed circuit board 1300 may include at least one first connector configured to face the z-axis direction.

[0114] The second printed circuit board 1500 (or connecting printed circuit board) may include a first portion 1500a disposed on one side of the rear surface of the second housing 420 (e.g., the surface facing the -z-axis direction) and a second portion 1500b disposed on the first housing 410. The first portion 1500a may be electrically connected to the second portion 1500b and may be secured to the second housing 420. The first portion 1500a may, for example, be electrically coupled to the first printed circuit board 1300. According to an embodiment, the first portion 1500a may include a second connector disposed facing the -z-axis direction and may be electrically connected to a first connector formed at the end of a portion of the first printed circuit board 1300 extending to the y-axis periphery. The second portion 1500b may be electrically connected to the first portion 1500a and may be configured such that at least a portion of the arrangement of the second portion 1500b changes in response to movement of the second housing 420. As an example, at least a portion of the second portion 1500b may include a corrugated shape or a folded shape. At least a portion of the second part 1500b may be configured to unfold when the second housing 420 moves in the -y-axis direction and fold when the second housing 420 moves in the y-axis direction. As an example, at least a portion of the second part 1500b may be formed of a ductile material. Optionally, a portion of the second part 1500b may be formed of a rigid type, and the bendable portion may be formed of a ductile material. Another portion of the second part 1500b may be electrically connected to the third printed circuit board 1400 (or the main printed circuit board). In this regard, a third connector may be disposed at one end of the second part 1500b, and the third connector disposed at the second part 1500b may be electrically connected to a fourth connector disposed at the third printed circuit board 1400.

[0115] The electronic device 101 with the above structure can receive power from the battery 205 at the third printed circuit board 1400, and in response to the control of the processor disposed on the third printed circuit board 1400, the power received by the battery 205 can be transmitted to the first type of auxiliary structure 300 through the third printed circuit board 1400, the second printed circuit board 1500 and the first printed circuit board 1300.

[0116] Figure 16 This is a view illustrating a first state related to the sliding detection of an electronic device according to an embodiment of the present disclosure, and Figure 17 This is a view showing a second state related to the sliding detection of an electronic device according to an embodiment of this disclosure.

[0117] Reference Figures 2 to 17The electronic device 101 may include at least a first housing 410, a second housing 420, and a fourth printed circuit board 1600. At least a portion of the second housing 420 may be coupled to the first housing 410 (e.g., on a surface facing the -z-axis direction), such that the second housing 420 is movable in the y-axis direction or the -y-axis direction. For example, as... Figure 16 As shown, when viewed from the z-axis direction (or the -z-axis direction), the electronic device 101 may have a first state in which the size 415_sp1 of the overlapping area of ​​the first housing 410 and the second housing 420 (or the length 415_L1 of one side of the overlapping area of ​​the first housing 410 and the second housing 420) is a first dimension, and as... Figure 17 As shown, when viewed from the z-axis direction (or the -z-axis direction), the electronic device 101 may have a second state in which the size 415_sp2 of the overlapping area of ​​the first housing 410 and the second housing 420 (or the length 415_L2 of one side of the overlapping area of ​​the first housing 410 and the second housing 420) is a second size larger than the first size. In the first state, a certain range of the -y-axis periphery of the first housing 410 and a certain range of the y-axis periphery of the second housing 420 may be configured to overlap with each other relative to the z-axis direction. In the first state, a certain range including the central portion of the first housing 410 and a certain range including the central portion of the second housing 420 may be configured to overlap with each other relative to the z-axis direction.

[0118] At least a portion of the fourth printed circuit board 1600 may be disposed on a surface of the first housing 410 (e.g., a surface facing the -z-axis direction). At least a portion of the fourth printed circuit board 1600 may be electrically connected to at least one of the first printed circuit board 1300, the second printed circuit board 1500, or the third printed circuit board 1400 described above. In the following description, a structure in which the third printed circuit board 1400 and the fourth printed circuit board 1600 are electrically connected will be described as an example. The fourth printed circuit board 1600 may include a plurality of sensors 1600_sr. The plurality of sensors 1600_sr (or each of the plurality of sensors 1600_sr) can sense changes in the magnetic flux of the magnet component 420_mg. As an example, the plurality of sensors 1600_sr can sense changes in magnetic flux when the magnet component 420_mg approaches or when the magnet component 420_mg moves away. Multiple sensors 1600_sr can transmit the sensed changes in magnetic flux to a third printed circuit board 1400 via wires formed on a plate 1600_bd. Furthermore, as shown, a magnet member 420_mg can be disposed on one side of the second housing 420 (e.g., one side of the sidewall in the -x-axis direction). The magnet member 420_mg can have a relative position within the first housing 410 that changes according to movement of the second housing 420. As an example, the magnet member 420_mg is movable according to movement of the second housing 420, and according to the movement of the magnet member 420_mg, multiple sensors 1600_sr disposed on a fourth printed circuit board 1600 can sense changes in magnetic flux according to the movement of the magnet member 420_mg, and can transmit the sensed changes to the third printed circuit board (e.g., ...). Figure 15 The third printed circuit board 1400).

[0119] Set on the third printed circuit board (e.g., Figure 15 The processor on the third printed circuit board 1400 can determine the current state of the electronic device 101 based on changes in the transmitted magnetic flux. For example, when a change in magnetic flux indicating that the magnet component 420_mg is positioned at the -y-axis periphery of the fourth printed circuit board 1600 is received from multiple sensors 1600_sr, the processor can determine the state of the electronic device 101 as follows: Figure 16 The extended position state shown is still as Figure 17The retracted position state is shown. Alternatively, the processor can sense the change in state of the electronic device 101 from a retracted position state to an extended position state or vice versa, based on changes in magnetic flux provided by multiple sensors 1600_sr. As an example, when a change in magnetic flux sensed by a sensor located around the y-axis of the fourth printed circuit board 1600 occurs, the processor can determine that the state has changed from a retracted position state to an extended position state. Alternatively, when a change in magnetic flux sensed by a sensor located around the -y-axis of the fourth printed circuit board 1600 occurs, the processor can determine that the state has changed from an extended position state to a retracted position state.
