[0041] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0042] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)).

[0043] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). According to one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). According to one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the selected at least one antenna.

[0044] In one embodiment, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0045] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0046] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service by itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101).

In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0047] FIG. 2 is a diagram showing an example of a first state of an electronic device according to an embodiment. FIG. 3 is a diagram showing an example of a second state of an electronic device according to an embodiment. As an example, state 11a of FIG. 2 is a diagram showing an example of the front and side of the electronic device in the retracted position, and state 11b of FIG. 2 is a diagram showing an example of the rear of the electronic device in the extended position. State 12a of FIG. 3 is a diagram showing an example of the front and side of the electronic device in the extended position, and state 12b of FIG. 3 is a diagram showing an example of the rear of the electronic device in the retracted position.

[0048] Referring to FIGS. 2 and 3, an electronic device (101) according to one embodiment may include a first case (210) (or basic housing, basic structure, first cover), a second case (220) (or front housing, front deco, front frame, second cover), a first housing (410) (or movable housing, slide plate, slide housing, slide structure, slide case, slide body, slide frame, slide bracket, first frame), a second housing (420) (second frame, fixed plate, fixed housing, fixed frame, fixed bracket), and a display assembly (360).

[0049] In one embodiment, the electronic device (101) may be a slidable type or a rollable type electronic device, and its state may be changed by movement of the second case (220) with respect to the first case (210) (or movement of the first housing (410) with respect to the second housing (420). For example, the states of the electronic device (101) may include state 11a and state 11b (e.g., retracted position, closed mode, reduced mode, slide-in mode, or minimum size mode), state 12a and state 12b (e.g., extended position, open mode, expanded mode, slide-out mode, or maximum size mode). The 11a state and the 11b state and the 12a state and the 12b state of the electronic device (101) can be determined according to the relative position of the second case (220) with respect to the first case (210). The electronic device (101) can be transformed (or switched) between the 11a state and the 11b state and the 12a state and the 12b state by a user's operation or a mechanical operation (e.g., a motor).

[0050] In one embodiment, the 11a state and the 11b state may mean a state in which the area (or size) of the exposure area of ​​the display assembly (360) exposed to (or forming the front surface of) the front surface (e.g., the surface facing the +z-axis direction) of the electronic device (101) is relatively reduced compared to the 12a state and the 12b state. The 12a state and the 12b state may mean a state in which the area (or size) of the exposure area of ​​the display assembly (360) exposed to (or forming the front surface of) the electronic device (101) is relatively expanded compared to the 11a state and the 11b state. For example, the 11a state and the 11b state may refer to a state in which the exposure area of ​​the display assembly (360) visually exposed to the front of the electronic device (101) has a minimum size, and the 12a state and the 12b state may refer to a state in which the exposure area of ​​the display assembly (360) exposed to the front of the electronic device (101) has a maximum size. Although not shown, the state of the electronic device (101) may further include at least one intermediate state (e.g., a partially expanded state or a partially open state) defined between the 11a state and the 11b state and the 12a state and the 12b state. For example, the at least one intermediate state may refer to one or more states in which the size of the exposure area of ​​the display assembly (360) is larger than the 11a state and the 11b state and smaller than the 12a state and the 12b state.

[0051] According to one embodiment, in the contracted position states corresponding to the 11a state and the 11b state, the first case (210) and the second case (220) of the electronic device (101) may form a closed state. As an example, the first case (210) may include a first case bottom (210_sd3) (or a first bottom side), a first case top (210_sd4) (or a first top side), a first case right part (210_sd1) (or a first right part), a first case left part (210_sd2) (or a first left part), and a case bottom part. The second case (220) may include a second case top (220_fr) (or a second top side), a second case right part (220_sd1) (or a second right part), and a second case left part (220_sd2) (or a second left part). Additionally, a bottom portion may be further arranged on the rear side of the second case (220). As another example, the electronic device (101) may include a form in which the first housing (410) and the second case (220) are integrated. In this case, the second case (220) may be integrated as a decoration of the first housing (410). A rear cover (440) may be arranged on the rear side of the electronic device (101). The rear cover (440) may include a first rear cover (441) arranged toward the rear side of the first case (210) and a second rear cover (442) arranged toward the rear side of the second case (220). As an example, the first rear cover (441) may be arranged below the bottom portion of the first case (210). A second rear cover (442) may be placed in the lower direction (e.g., in the -z-axis direction) of the second case (220) (or below the bottom of the second case (220)). In the 11a state and the 11b state, the first case (210) and the second case (220) of the electronic device (101) may be placed in close proximity within a predefined distance.For example, in the 11a state and the 11b state, one end of the right side of the first case (210_sd1) and one end of the right side of the second case (220_sd1) may be placed in contact with each other or may be placed in close proximity within a predefined distance (e.g., several um to several mm). For example, in the 11a state and the 11b state, one end of the left side of the first case (210_sd2) and one end of the left side of the second case (220_sd2) may be placed in contact with each other or may be placed in close proximity within a predefined distance. Alternatively, in states 12a and 12b, one side of the first case (210) (e.g., the end in the y-axis direction) and one side of the second case (220) (e.g., the end in the -y-axis direction) may be in contact with each other or may be spaced apart by a predefined second interval (e.g., an interval of a length greater than the first interval or a distance of several mm to several cm or more).

[0052] According to one embodiment, referring to the 12a state and the 12b state, the second case (220) may change the state of the electronic device (101) by sliding relative to the first case (210). For example, the electronic device (101) may be changed to the 12a state and the 12b state by the second case (220) moving in a first direction (or y-axis direction) relative to the first case (210) in the 11a state and the 11b state. Conversely, the electronic device (101) may be changed to the 11a state and the 11b state by the second case (220) moving in a second direction (or - y-axis direction) opposite to the first direction relative to the first case (210) in the 12a state and the 12b state.

[0053] In one embodiment, the display assembly (360) may change the size of the exposure area visually exposed to the front direction of the electronic device (101) in response to the sliding motion of the second case (220). The display assembly (360) may be configured such that the area exposed to the front direction of the electronic device (101) expands or contracts by rotating and linearly moving at least a portion thereof in response to the sliding motion of the second case (220) while being supported by other components of the electronic device (101). The display assembly (360) may include at least a partially flexible portion. For example, the display included in the display assembly (360) may be a flexible display.

[0054] In one embodiment, the display assembly (360) may include a first screen area (261) forming a front surface, a first extension area (263) extending from the first screen area (261) and disposed inside the first case (210), and a second extension area (262) in the contracted position as illustrated in FIGS. 11a and 11b. The first extension area (263) may include an area that forms a curved surface and is positioned between the first screen area (261) and the second extension area (262) in the contracted position. The second extension area (262) may include an area that is disposed to face the bottom surface of the first case (210) in the contracted position. The second extension area (262) may include a non-display area in which pixels are not disposed at least in a portion. Alternatively, the entire second extension area (262) may include display areas.

[0055] According to one embodiment, in the retracted position, at least a portion of the first extension region (263) may be covered by the first case top (210_sd4), 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 first case bottom) of the first case (210). The display assembly (360) may include, in the 12a and 12b extended positions, a first screen region (261) forming the front surface, and at least a portion of a first extension region (263) and a 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). Alternatively, in the extended position, the first screen area (261), the first extended area (263), and the second extended area (262) may form the front surface of the display assembly (360). The electronic device (101) may have a partially retracted position or a partially extended position that is intermediate between the retracted position and the extended position. In this case, a portion of the second extended area (262) (or an area in which pixels capable of displaying a screen are arranged and which is arranged in the rear direction of the first screen area (261) in the retracted position) may be arranged on the front surface (e.g., a side observable from the outside), and another portion may be arranged to face the curved area where the first extended area (263) is arranged when in the retracted position or the rear direction (e.g., the -z-axis direction). Alternatively, in the partially retracted position, a portion of the second extended area (262) may be arranged on the front surface, and another portion may be arranged on the curved area where the first extended area (263) is arranged when in the retracted position. Alternatively, depending on the degree of partial contraction (or degree of partial extension), the size of the area disposed in the front among the second extension areas (262) may be different.As an example, when 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) are in an extended position position where they are arranged on the front side, the first housing (410) may be partially exposed when the side of the electronic device (101) is observed, and the second housing (420) may be partially exposed when the rear side is observed.

[0056] The second extension region (262) may be introduced into the interior of the first case (210) (e.g., a slide-in operation) or withdrawn out of the exterior of the first case (210) (e.g., a slide-out operation) depending on whether the first case (210) slides relative to the second case (220) (or whether the second case (220) slides relative to the first case (210). In one embodiment disclosed in the present document, 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 mean that their shapes or properties are different from each other.

[0057] The structure of the electronic device (101) described below is an example of an electronic device (101) in which the area of ​​the screen display area can be varied, and an electronic device (101) in which the screen display area can be varied can be implemented in various ways other than the structure disclosed in this document. The term "state" in this document can be understood to refer to the operation of the electronic device (101) or the structural form, shape, or shape of the display.

[0059] Referring to FIGS. 2 to 4, an electronic device (101) according to an embodiment may include a first case (210), a second case (220), a display assembly (360), a first housing (410), side members (481, 482), a second housing (420), a first type auxiliary structure (300) (or structure, a first type structure, a display support structure, a damage prevention and waterproof or dustproof structure), and a rear cover (440) (or back cover). For example, the electronic device (101) may be a rollable electronic device or a rollable electronic device.

[0060] According to one embodiment, the first case (210) may form at least a portion of the exterior of the electronic device (101). The first case (210) may provide a space in which various electronic components are arranged. The second case (220) may be slidably connected to the first case (210). For example, the second case (220) may be moved in the +Y direction from the first case (210) or may be moved in the -Y direction relative to the first case (210). However, this is merely exemplary, and the direction in which the second case (220) is moved is not limited thereto. For example, the second case (220) may be pulled out in the +X direction from the first case (210) or may be moved in the -X direction relative to the first case (210) so that the display (260) may be configured to extend in the width direction (e.g., the X-axis direction) (e.g., the right or left direction) of the electronic device (101). In this case, the electronic device (101) can be changed so that the structure of the currently illustrated drawing slides in the x-axis direction.

The first case top (210_sd4) may extend in the y-axis direction parallel to the first case bottom (210_bt) from above the first case bottom (210_sd3). The y-axis length of the first case top (210_sd4) may be formed to be shorter than the y-axis length of the first case bottom (210_bt). The lengths of the right side of the first case (210_sd1), the left side of the first case (210_sd2), and the bottom side of the first case (210_bt) in the y-axis direction may be formed to be the same. A printed circuit board (204), a battery (205), a first housing (410), and a portion of a second housing (420) may be installed within the first case (210). A portion of a rear cover (440) (e.g., a first rear cover (441)) may be placed under the bottom side of the first case (210_bt). The first case (210) may form a case groove (210_rc) including a first case bottom (210_sd3), a first case top (210_sd4), a portion of the first case right side (210_sd1), a portion of the first case left side (210_sd2), and a portion of the first case bottom side (210_bt). A first type auxiliary structure (300) may be disposed within the case groove (210_rc). At least a portion of the display assembly (360) may be disposed within the case groove (210_rc). Within the case groove (210_rc), the first type auxiliary structure (300) and a portion of the display assembly (360) (e.g., the first extension region (263)) may be disposed to face each other.

[0062] According to one embodiment, the first type auxiliary structure (300) may be moved toward the bottom surface of the case home (210_rc) or moved again in the -y-axis direction from a state in which it has been moved in the y-axis direction. As an example, the first type auxiliary structure (300) may be fixed to the inner surface of the first case bottom (210_sd3) (e.g., the bottom surface of the first case bottom (210_sd3) observed in the y-axis direction, the opposite surface of the first case bottom (210_sd3) observed from the outside). In response to the control of the processor of the electronic device (101) (e.g., the processor (120) of FIG. 1), at least a portion of the first type auxiliary structure (300) may be moved in the y-axis direction (or in the first extension region (263).

[0063] According to one embodiment, the second case (220) may include a portion (e.g., a second case top portion (220_fr)) that surrounds at least a portion of an upper edge (e.g., a -y-axis edge) of the display assembly (360) or the first housing (410), a second case left portion (220_sd2) that extends in the -y-axis direction from one edge (e.g., a left edge) of the second case top portion (220_fr), and a second case right portion (220_sd1) that extends in the -y-axis direction from the other edge (e.g., a right edge) of the second case top portion (220_fr). The second case (220) described above includes a C-shape and may be fastened (or coupled) to the first housing (410) in the y-axis direction from the -y-axis direction. At least a portion of the first case (210) (e.g., the left side of the first case (210_sd2) and the right side of the first case (210_sd1)) and at least a portion of the second case (220) (e.g., the left side of the second case (220_sd2) and the right side of the second case (220_sd1)) may be arranged to face each other.

[0064] According to one embodiment, at least a portion of the first housing (410) may be positioned in an internal space of the electronic device (101) formed by the first case (210) and the second case (220). At least a portion of the first housing (410) may be coupled to the second case (220) or formed integrally with the second case (220). The second case (220) and the first housing (410) may form a first frame (or a first frame structure, a first framework) that can withstand a load of a certain size or more, thereby contributing to the durability or rigidity of the electronic device (101). Electronic components or various members related to 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 rear direction (e.g., a -Z direction). The first housing (410) can support at least a portion of the display (260) (e.g., the first screen area (261)). The first housing (410) can be attached (or bonded) to at least a portion of the display (260) (e.g., the first screen area (261) of the display) via an adhesive member (not shown). The first housing (410) can move linearly back and forth in the +Y / -Y direction. The first housing (410) can slide with respect to the first case (210) together with the second case (220).

[0065] According to one embodiment, the second housing (420) (or, fixed bracket, fixed support structure, fixed support member, fixed frame, first plate) may be positioned in an internal space of the electronic device (101) formed by the first case (210). The second housing (420) may be connected to the first case (210). Alternatively, at least a portion of the second housing (420) may be formed integrally with the first case (210). The first case (210) and the second housing (420) may form a second frame (or, second frame structure, second framework) capable of withstanding a load, thereby contributing to the durability or rigidity of the electronic device (101). Electronic components, or various components related to electronic components, may be placed on or supported by the second frame. As an example, the battery (205) and the printed circuit board (204) may be placed in or supported by the second housing (420) or the second frame.

[0066] According to one embodiment, the second housing (420) can 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). For example, the second housing (420) includes a curved region (421), and the second housing (420) can be positioned toward the first extension region (263) of the display (260) depending on the contracted or extended position of the electronic device (101). When the second case (220) is slid, the first extension region (263) and the second extension region (262) of the display (260) can be pulled out from the internal space of the first case (210) or introduced into the internal space of the first case (210).

[0067] According to one embodiment, the side members (481, 482) may guide the movement path of the display assembly (360) when the second case (220) slides with respect to the first case (210). For example, the side members (481, 482) may be connected to the first case (210) and may not slide even when the second case (220) slides with respect to the first case (210). In another example, the side members (481, 482) may be connected to the second case (220) and may slide with respect to the first case (210) together with the second case (220). At least one side member (481, 482) may be provided. For example, the side members (481, 482) may be provided as a pair and may be positioned on both sides (e.g., in the -X direction and the +X direction) of the first case (210). For example, among the side members (481, 482), the first side member (481) arranged on the right side may be connected to one side (e.g., the -X direction end) of the first case (210), and the second side member (482) arranged on the left side may be connected to the other side (e.g., the +X direction end) of the first case (210). However, this is merely exemplary, and the positions and / or numbers of the side members (481, 482) are not limited thereto.

[0068] According to one embodiment, at least a portion of the display assembly (360) may be supported by at least one of the first case (210), the second case (220), the first housing (410), or the second housing (420). For example, a portion of the display assembly (360) may be supported by the first housing (410), and another portion may be supported by the second housing (420). The display assembly (360) may have a display area that changes depending on relative movement of the second case (220) with respect to the first case (210) (or relative movement of the first housing (410) with respect to the second housing (420). For example, when the first housing (410) is pulled out from the second housing (420), the display (260) area of ​​the display assembly (360) may be more visually exposed, and the area displaying the screen of the display (260) may be expanded to the first screen area (261), the first extension area (263), and the second extension area (262). When the first housing (410) is inserted into the second housing (420), the area where the display (260) of the display assembly (360) is visually exposed may be reduced, and the area displaying the screen of the display (260) may be reduced to the first screen area (261). The display assembly (360) may include a display, a support sheet, and a multi-bar assembly (or, a multi-joint hinge structure, a support structure). However, this is exemplary, and the configuration of the display assembly (360) is not limited thereto. For example, the display assembly (360) may include various layers, such as a cover layer and / or a touch panel.

[0069] According to one embodiment, the display (260) can visually display information. At least a portion of the display (260) can be formed to be flexible. The display (260) can have a display area that is visually exposed to the outside changed depending on the relative movement of the second case (220) with respect to the first case (210) (or the relative movement of the first housing (410) with respect to the second housing (420). Hereinafter, for convenience of explanation, the direction in which information is visually displayed on the display (260) is referred to as the front direction (e.g., +Z direction), and the direction opposite to the front direction is referred to as the back (or rear) direction (e.g., -Z direction).

[0070] According to one embodiment, the rear cover (440) may be positioned or coupled to the rear of the first case (210) and the second case (220) to form at least a portion of the exterior of the electronic device (101). For example, the rear cover (440) may include a first rear cover (441) coupled to the first case bottom (210_bt) of the first case (210), and a second rear cover (442) coupled to the rear of the second case (220). The rear cover (440) may provide a decorative effect on the exterior of the electronic device (101).

[0073] Referring to FIGS. 2 to 5, the first case (210) may include a first case bottom (210_sd3), a first case top (210_sd4), a first case right side (210_sd1), a first case left side (210_sd2), and a first case bottom side (210_bt), as mentioned above. The first case bottom side (210_bt) may have, for example, a surface having a size similar to or the same as the bottom surface size of the second housing (420) described above. Alternatively, the first case bottom side (210_bt) may have a size corresponding to the size of the first rear cover (441). The first case bottom side (210_bt) may include at least one hole penetrating in the front and rear directions (e.g., in the z-axis and -z-axis directions). At the right edge of the first case bottom part (210_bt), a first case right part (210_sd1) may be disposed at a predetermined angle from the bottom surface of the first case bottom part (210_bt) (or in a direction perpendicular to the bottom surface or in the z-axis direction) and having a predefined height (e.g., a height corresponding to the thickness of the electronic device (101)). At the left edge of the first case bottom part (210_bt), a first case left part (210_sd2) may be disposed at a predetermined angle from the bottom surface of the first case bottom part (210_bt) (or in a direction perpendicular to the bottom surface or in the z-axis direction) and having a predefined height (e.g., a height corresponding to the thickness of the electronic device (101)). At the lower edge of the first case bottom portion (210_bt), an extended first case bottom portion (210_sd3) having a predefined height (e.g., a height corresponding to the thickness of the electronic device (101)) at a predetermined angle from the bottom surface of the first case bottom portion (210_bt) (or in the direction perpendicular to the bottom surface or in the z-axis direction) can be placed.Both edges of the first case bottom (210_sd3) may connect one upper side of the left side of the first case (210_sd2) and one upper side of the right side of the first case (210_sd1). The first case top (210_sd4) may be arranged to extend in the y-axis direction from the upper edge (e.g., the edge in the z-axis direction) of the first case bottom (210_sd3). Correspondingly, the lower edge of the first case top (210_sd4) may be connected to the upper edge of the first case bottom (210_sd3), and both edges of the first case top (210_sd4) may be connected to one side of the left side of the first case (210_sd2) and one side of the right side of the first case (210_sd1). According to one embodiment, a lower edge (e.g., an edge in the -y-axis direction) of the first case (210) may be closed by a first case bottom (210_sd3). Alternatively, a case groove (210_rc) (or groove, structure arrangement groove) formed by a first case bottom (210_sd3), a first case top (210_sd4), a part of a first case left side (210_sd2), and a part of a first case right side (210_sd1) may be arranged (or formed) on the lower edge of the first case (210). A first type auxiliary structure (300) may be arranged (or fixed) on the case groove (210_rc). According to one embodiment, the y-axis length of the first case top (210_sd4) may be formed to be different from the y-axis length of at least one of the first case right side (210_sd1) or the second case left side (210_sd2). For example, the y-axis length of the first case top (210_sd4) may be smaller than the y-axis length of the first case right side (210_sd1). Alternatively, the y-axis length of the first case top (210_sd4) may be formed to be smaller than or similar to the height of the first case bottom (210_sd3).

[0074] Referring to states 503 and 505 of FIGS. 2 to 5 and at least a portion of FIG. 6, the first type auxiliary structure (300) may include a structure substrate (310) (or substrate), a support structure (320) (or protective structure), and a plurality of actuators (330).

[0075] The above-described structure substrate (310) may include a base substrate (310_bd) formed such that the length in the x-axis direction is longer than the length in the z-axis or y-axis. As an example, a length of one side of the base substrate (310_bd) (e.g., a length in the x-axis direction) may have a size similar to or the same as (or smaller than) a length of one side of the case groove (210_rc) of the first case (210) (e.g., a length in the x-axis direction). The base substrate (310_bd) may be fixed to a bottom surface of the case groove (210_rc). The base substrate (310_bd) may include a plurality of holes (310_h) in which at least a portion of the plurality of actuators (330) may be arranged. The plurality of holes (310_h) may be formed to penetrate the front and rear surfaces (e.g., surfaces in the y-axis to -y-axis directions) of the base substrate (310_bd). The above plurality of holes (310_h) may be regularly formed, for example, according to a certain pattern. As an example, the base substrate (310_bd) may include a plurality of holes (310_h) corresponding to the number of actuators (330).

[0076] According to one embodiment, the structure substrate (310) may be formed by overlapping a plurality of layers. For example, wiring capable of supplying power to the plurality of actuators (330) may be arranged on at least one of the plurality of layers of the structure substrate (310). For example, the structure substrate (310) may include a wiring layer, support layers arranged on the front and rear surfaces of the wiring layer, and at least one adhesive layer used for adhesion to the bottom surface of the case groove (210_rc). Alternatively, the structure substrate (310) may be composed of a single layer in which a groove for the wiring is formed. For example, at least one layer of the structure substrate (310) may include a board connection portion (311) that may be electrically connected to a printed circuit board (204) of an electronic device (101) (or a first printed circuit board (1300) described below). The substrate connection portion (311) may be arranged to protrude from one side of the base substrate (310_bd). For example, the substrate connection portion (311) may be arranged to protrude in the y-axis direction from a point of the base substrate (310_bd). The substrate connection portion (311) may be arranged (protruded) in the rear direction (e.g., a surface observed in the -z-axis direction) of the first case bottom portion (210_bt) through a through hole formed in the first case bottom portion (210_bt). At least one terminal (311_t) (or electrode) may be arranged on the substrate connection portion (311). The above terminal (311_t) is electrically connected to wires formed on the base substrate (310_bd) of the structure substrate (310), and can be used to supply power to a plurality of actuators (330) through the printed circuit board (204) (or the first printed circuit board (1300) described below).

[0077] According to one embodiment, the structure substrate (310) may be formed of a material having higher rigidity than the support structure (320). For example, at least a portion of the structure substrate (310) may be formed of a metal material. Alternatively, at least a portion of the structure substrate (310) may be formed of a reinforced plastic or a polymer (e.g., PET (polyethylene terephthalate), PMMA (polymethyl methacrylate)) material capable of providing rigidity greater than a specified amount. Alternatively, when the structure substrate (310) is composed of a plurality of layers, the plurality of layers may be formed of different materials. For example, among the plurality of layers of the structure substrate (310), one layer facing the bottom surface of the case groove (210_rc) may include an adhesive layer. The adhesive layer may bond an area of ​​one surface of the structure substrate (310) where a plurality of actuators (330) are not formed and the bottom surface of the case groove (210_rc).

[0078] Referring to FIGS. 2 to 6 and 7, the support structure (320) may be disposed in the direction of (or on) the first surface (e.g., the surface facing the y-axis direction) of the structure substrate (310). The support structure (320) and the structure substrate (310) may be spaced apart from each other. Alternatively, an air gap may be formed between the support structure (320) and the structure substrate (310). The support structure (320) may be moved in the y-axis direction or the -y-axis direction from the structure substrate (310) in response to the operation of a plurality of actuators (330). For example, the support structure (320) may be moved in the y-axis direction from the structure substrate (310) when the screen areas of the electronic device (101) are fixed (e.g., in a contracted position or an extended position) and may come into contact with (or come closer to by less than a predefined first distance) an area of ​​the display assembly (360) (e.g., a first extended area (263) of the display (260) in the contracted position or a second extended area (262) of the display (260) in the extended position). In this regard, at least a part of the back surface (320_bk) of the support structure (320) facing the structure substrate (310) may be formed flat (or the entire surface may be formed flat), and at least a part of the front surface (320_fr) of the support structure (320) facing the display assembly (360) may be formed curved (or the entire surface may be formed concave). Support grooves (320_sh) that are connected to a plurality of actuators (330) may be arranged on the back surface (320_bk) of the support structure (320). The number of support grooves (320_sh) may correspond to the number of actuators (330).

[0079] According to one embodiment, the support structure (320) may be formed of a material having lower rigidity (or higher (or greater) ductility, or greater elasticity) than the structure substrate (310). For example, at least a portion of the support structure (320) may be formed of at least one material selected from the group consisting of rubber, silicone, fiber (e.g., microfiber, quilt, fleece, cotton, flannel, velvet, veil), sponge structure, corduroy, and polymer materials. As an example, the support structure (320) may include a plurality of layers. Correspondingly, at least some of the plurality of layers of the support structure (320) may be formed of different materials. For example, a first layer of the support structure (320) facing the structure substrate (310) may be formed of a material having relatively higher rigidity than other layers of the support structure (320) (e.g., plastic, reinforced plastic, plastic alloy, or polymer material having a rigidity higher than a certain reference value). The second layer placed on the first layer of the support structure (320) may be formed of a soft material (e.g., rubber, silicone, filament, or a polymer material having a lower ductility (or less ductility) than the rigidity of the first layer) that can prevent damage to the display assembly (360) when the support structure (320) comes into contact with the display assembly (360) due to an external impact. Alternatively, the support structure (320) may be formed of different materials in parts (or by location).

[0080] As an example, the support structure (320) may include a central region (320_cen), an upper region (320_up) of the structure, and a lower region (320_low) of the structure. The upper region (320_up) of the structure and the lower region (320_low) of the structure may include regions that protrude more in the y-axis direction than the central region (320_cen) based on the back surface (320_bk) of the support structure (320). Alternatively, the upper region (320_up) of the structure and the lower region (320_low) may include edge regions in the z-axis or -z-axis direction based on the central region (320_cen). At least a portion of the upper region (320_up) of the structure may include a region that is arranged close to the upper end (210_sd4) of the first case among the support structures (320). At least a portion of the lower region (320_low) of the above structure may include a region disposed close to the first case bottom portion (210_bt) of the above support structure (320).

[0081] According to one embodiment, a region of a concave portion of the support structure (320) (e.g., a central region (320_cen)) (e.g., a concave central line in the x-axis direction) may be formed of a first material (e.g., a rubber or silicone material), and at least a portion of upper and lower edge regions (e.g., an upper structure region (320_up) and a lower structure region (320_low)) relative to the central region (320_cen) may be formed of a second material (e.g., a filament or fiber material) different from the first material. Alternatively, at least a portion of the central region (320_cen) and the lower region (320_low) of the support structure (320) may be formed of a first material (e.g., a material capable of achieving the purpose of shock absorption, such as a rubber or silicone material), and at least a portion of the upper region (320_up) of the structure may be formed of a second material different from the first material (e.g., a material capable of achieving the purpose of waterproofing or dustproofing, such as a fleece or fiber material). As another example, the central region (320_cen), the lower region (320_low) of the structure, and the upper region (320_up) of the structure may be formed of different materials.

[0082] Referring to FIGS. 2 to 8, at least some of the plurality of actuators (330) may be disposed in a plurality of holes (310_h) formed in a structure substrate (310) (e.g., a base substrate (310_bd)). Each of the plurality of actuators (330) may have a state in which power is not supplied (or a state in which power is not supplied) and a state in which power is supplied (or a state in which power is supplied). Each of the plurality of actuators (330) may advance at least a portion of the support structure (320) in the first surface direction of the structure substrate (310) (e.g., the y-axis direction or the direction toward the display assembly (360)) when power is supplied (or when power is not supplied). Each of the plurality of actuators (330) can retract at least a portion of the support structure (320) in the direction of the second surface of the structure substrate (310) (e.g., in the -y-axis direction or in the direction of the bottom surface of the case groove (210_rc)) when power is cut off (or when power is supplied in the opposite direction, or when the cut-off power is supplied). For example, the plurality of actuators (330) can move the support structure (320) toward the display assembly (360) or away from the display assembly (360).

[0083] According to one embodiment, the actuator (330) may include a base portion (331) and a pillar portion (332), as shown in FIG. 8. At least a portion of the base portion (331) may have a semi-spherical shape with a predetermined thickness and a space formed in the center. Alternatively, the base portion (331) may have an umbrella shape that is spread out in a circular manner around the ceiling, with the inner or outer portion of the ceiling partially flat. The base portion (331) may be shaped such that the protrusion direction of the ceiling becomes opposite when power is supplied from the outside (or when power is cut off). A pillar portion (332) may be arranged at the inner center of the base portion (331). As an example, the pillar portion (332) may have a cylindrical shape with one cross-section forming a circle. One end of the pillar portion (332) may be fixed (or bonded) to the inner side of the ceiling of the base portion (331). The above pillar portion (332) may be arranged perpendicular to the ceiling center of the base portion (331). The length of the pillar portion (332) in the y-axis direction may be formed to be greater than the thickness of the base portion (331) in the y-axis direction. Accordingly, a plurality of actuators (330) may be coupled (or bonded) to the back surface (320_bk) (or support grooves (320_sh)) of the support structure (320) by penetrating a plurality of holes (310_h) formed in the base substrate (310_bd) of the structure substrate (310). The pillar portion (332) may maintain its shape or form regardless of the power supply.

[0084] FIG. 9 is a drawing showing a first arrangement state of an electronic device according to an embodiment. As an example, state 901 of FIG. 9 is a drawing showing a portion of the front surface of an electronic device (101) when the electronic device (101) is in the first arrangement state, and state 903 of FIG. 9 is a drawing showing an example of a cross-section cut along the A1-A1` cutting line of a portion of the electronic device (101) in state 901.

[0085] Referring to states 901 and 903 of FIGS. 2 to 9, the electronic device (101) may include, for example, a first housing (410), a second housing (420), a display assembly (360), a first case (210), and a first type auxiliary structure (300). Additionally or alternatively, the electronic device (101) may further include at least some of the other components described above in FIG. 4.

[0086] According to one embodiment, the first arrangement state of the first type auxiliary structure (300) may include a state in which the electronic device (101) changes from a contracted position to an extended position or from an extended position to a contracted position. The user may instruct a position change using at least one input means provided in the electronic device (101). The at least one input means may include at least one of a virtual key that is output through at least one button provided in the electronic device (101) or a screen user interface of the display (260) and can instruct a contracted or extended position change, at least one sensor that can sense a gesture action corresponding to a contracted or extended position change, and a microphone that can receive a contracted or extended position change as a voice.

[0087] According to one embodiment, the first case (210) may include a first case bottom (210_sd3), a first case top (210_sd4), and a first case bottom portion (210_bt). Additionally or alternatively, the first case (210) may further include a first case right portion (210_sd1) and a first case left portion (210_sd2). According to one 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 under the first case bottom portion (210_bt). The first case bottom portion (210_sd3), the first case top portion (210_sd4), and the first case bottom portion (210_bt) may form a case groove (210_rc). Alternatively, the first case bottom (210_sd3), the first case top (210_sd4), the first case bottom (210_bt), a portion of the first case right side (210_sd1), and a portion of the first case left side (210_sd2) may form a case groove (210_rc). At least a portion of the first type auxiliary structure (300) may be placed (or fixed) in the case groove (210_rc). In this regard, a structure placement groove (210_sh) in which at least a portion of the first type auxiliary structure (300) is seated may be formed in the inner surface of the case groove (210_rc) (or the inner surface of the first case bottom (210_sd3)). The above structure arrangement groove (210_sh) may be formed by engraving at least a portion (or item) in the -y-axis direction on the inner surface of the case groove (210_rc) (or the inner bottom surface of the first case bottom (210_sd3)). The above structure arrangement groove (210_sh) may include a shape corresponding to the back surface of the first type auxiliary structure (300) (or at least a portion of the back surface of the structure substrate (310) on which the base portions (331) of the plurality of actuators (330) are arranged in a certain pattern).For example, at least a portion of the structure placement groove (210_sh) may include a groove in which the base portions (331) of the plurality of actuators (330) are placed. As an example, at least a portion of the structure placement groove (210_sh) may include a number of grooves corresponding to the number of the plurality of actuators (330).

[0088] As described above, the first type auxiliary structure (300) may include a structure substrate (310), a support structure (320), and a plurality of actuators (330). At least a portion of the structure substrate (310) may be fixed or adhered to the inner surface of the first case bottom (210_sd3). In this regard, the electronic device (101) may further include an adhesive layer (310_ad) between the inner surface of the first case bottom (210_sd3) and one surface (e.g., a surface facing the -y axis) of the structure substrate (310). As another example, the adhesive layer (310_ad) may be included in the first type auxiliary structure (300). At least a portion of the plurality of actuators (330) may be arranged in a plurality of holes (e.g., 310_h of FIG. 6) formed to penetrate the front and rear surfaces of the structure substrate (310). For example, when the first type auxiliary structure (300) is in the first arrangement state, the base portion (331) may be arranged (or formed) to be convex toward the back surface (e.g., the surface observed in the -y-axis direction) of the structure substrate (310), a portion of the pillar portion (332) may be positioned within a plurality of holes (310_h in FIG. 6), and the remaining portion of the pillar portion (332) may be arranged to protrude toward the front surface (e.g., the surface observed in the y-axis direction or the surface facing the direction in which the support structure (320) is arranged) of the structure substrate (310). As an example, the remaining portion of the pillar portion (332) may be inserted and fixed into support grooves (320_sh) formed in the support structure (320).

[0089] According to one embodiment, the support structure (320) may include a concave shape 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 identical or similar to the curvature of the display assembly (360) (or the curvature of the display curved surface area). Alternatively, the curvature of the curved surface of the support structure (320) may be formed to be identical or similar within a certain error range to the curvature of the curved surface area (421) of the second housing (420). Alternatively, the curvature of the curved surface of the support structure (320) may be identical or similar to the curvature of the first extended area (263) in the contracted position.

[0090] According to one embodiment, the display assembly (360) may include a display (260) and a multi-bar assembly (260a). The display (260) may include a first screen area (261), a first extension area (263), and a second extension area (262). The display curved area (260_cr) may include, for example, at least a portion of the first extension area (263) and the second extension area (262). As an example, the display curved area (260_cr) may include the first extension area (263) in a state immediately before changing from a contracted position to an extended position (or in a contracted position state). When at least a portion of the first extension area (263) is moved forward (e.g., in the z-axis direction) after the contracted position, the display curved area (260_cr) may include a portion of the first extension area (263) and at least a portion of the second extension area (262). Alternatively, when the extension position is completed, the display curved area (260_cr) may include at least a portion of the second extension area (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 members and the plurality of multi-bars.

[0091] According to one embodiment, in the first arrangement state where the display assembly (360) changes from the contracted position to the extended position (or from the extended position to the contracted position), a gap of a first size may be formed between the support structure (320) and the display curved area (260_cr). The gap of the first size may provide a non-contact state between a portion of the display assembly (360) (e.g., a portion of the display assembly (360) located on the curved area (421) of the second housing (420)) and the first type auxiliary structure (300), thereby preventing (or improving) damage or deformation of the display assembly (360) (or the display (260)) by the first type auxiliary structure (300). Additionally or alternatively, the first type auxiliary structure (300) may prevent foreign substances from entering the case groove (210_rc).

[0092] FIG. 10 is a drawing showing a second arrangement state of an electronic device according to an embodiment. As an example, state 1001 of FIG. 10 is a drawing showing a portion of the front surface of an electronic device (101) when the electronic device (101) is in the second arrangement state, and state 1003 of FIG. 10 is a drawing showing an example of a cross-section cut along the A2-A2` cutting line of a portion of an electronic device (101) in state 1001.

[0093] Referring to states 1001 and 1003 of FIGS. 2 to 10, the electronic device (101) may include, for example, a first housing (410), a second housing (420), a display assembly (360), a first case (210), and a first type auxiliary structure (300). Additionally or alternatively, the electronic device (101) may further include at least some of the other components described above in FIG. 4. As an example, the first type auxiliary structure (300) may include a structure substrate (310), a support structure (320), a plurality of actuators (330), and may further include an adhesive layer (310_ad) disposed between the structure substrate (310) and at least a portion of the inner side of the case groove (210_rc). The case groove (210_rc) of the first case (210) may include a structure placement groove (210_sh) in which at least a portion of the first type auxiliary structure (300) is placed. The structure placement groove (210_sh) may be configured (or formed) so that at least a portion of the base portion (331) of a plurality of actuators (330) may be placed.

[0094] According to one embodiment, the second arrangement state of the first type auxiliary structure (300) may include a state in which the electronic device (101) is in a contracted position or an extended position. Alternatively, according to one embodiment, the second arrangement state of the illustrated FIG. 10 may include an intermediate state in which the display assembly (360) is temporarily fixed. The illustrated drawing is a drawing showing an example of a contracted position state. In the case of the extended position, the second extended area (262) may be partially arranged in the display curved area (260_cr) described above in FIG. 9, or at least a portion of the first extended area (263) and the second extended area (262) may be arranged toward the front (z-axis direction) together with the first screen area (261).

[0095] In the second arrangement state, the base portions (331) of the plurality of actuators (330) may protrude in the y-axis direction by the supplied power (or by the power supply being cut off). Alternatively, the base portions (331) of the plurality of actuators (330) may be arranged (or formed, deformed) to be convex in the y-axis direction. Correspondingly, the pillar portion (332) protruding in the y-axis direction from the center of the base portion (331) may be arranged to protrude further in the y-axis direction compared to the previous state. As the pillar portion (332) moves, the support structure (320) connected to the pillar portion (332) may move in the y-axis direction with respect to the structure substrate (310). For example, the position of the support structure (320) within the case groove (210_rc) may change. As an example, a gap having a second size smaller than a previously formed first size gap may be formed between one side of the support structure (320) (e.g., a side facing the y-axis direction) and a portion of the display assembly (360) (e.g., a first extension region (263)). Alternatively, one side of the support structure (320) (e.g., a side facing the y-axis direction) and a portion of the display assembly (360) may be in contact. According to one embodiment, considering a portion in which a contracted position or an extended position state is maintained longer than a changed state (e.g., a state in which the contracted position or the extended position is changed to the contracted position), the plurality of actuators (330) may maintain the second arrangement state described in FIG. 10 when the power is not supplied, and may maintain the first arrangement state described in FIG. 9 when the power is supplied. However, the present disclosure is not limited thereto, and may be set to the opposite case.

[0096] By maintaining the support structure (320) of the first type auxiliary structure (300) in contact with a portion of the display assembly (360), damage to a portion of the display assembly (360) can be prevented when an impact is applied from the outside. In addition, by maintaining the support structure (320) of the first type auxiliary structure (300) in contact with a portion of the display assembly (360), the space (or gap) between the first case top (210_sd4) and the display assembly (360) is blocked, so that foreign substances can be prevented from entering through the gap between the first case top (210_sd4) and the display assembly (360).

[0097] Fig. 11 is a drawing showing an example of a second type auxiliary structure according to one embodiment. In Fig. 11, state 1101 illustrates a deformation form of a second type auxiliary structure (300a) (or structure, second type structure) in a first arrangement state, and state 1101 illustrates a deformation form of a second type auxiliary structure (300a) in a second arrangement state.

[0098] Referring to FIGS. 2 to 11, the second type auxiliary structure (300a) may include a structure substrate (310), a first support structure (321a), a second support structure (321b), and a plurality of actuators (330). The structure substrate (310) may have the same structure as the structure substrate (310) described above in FIGS. 4 to 10. For example, the structure substrate (310) may include a base substrate (310_bd) and a substrate connection portion (311). Wiring connected to the plurality of actuators (330) may be arranged on the base substrate (310_bd), and at least one terminal may be arranged on the substrate connection portion (311). The base substrate (310_bd) may be formed with a plurality of holes (e.g., holes (310_h) of FIG. 6) in which at least some of the plurality of actuators (330) are arranged.

[0099] The first support structure (321a) may include a flat first surface (e.g., a surface facing one surface of the structure substrate (310) (e.g., a surface facing the y-axis)) and a second surface (e.g., a surface opposite to the first surface) having a certain slope or being partially curved. At least one first support groove (e.g., the support groove (320_sh) described above in FIG. 9) into which a pillar portion (332) of the actuator (330) is inserted may be formed on at least a portion of the first surface of the first support structure (321a). The first support structure (321a) may include a structure having a shape in which the width of the z-axis cross-section increases from the -z-axis toward the z-axis direction. As an example, among the widths of the z-axis cross-section of the first support structure (321a), the width of the edge in the z-axis direction may be greater than the width of the edge in the -z-axis direction. The degree of inclination or curvature (or curvature) of the second surface of the first support structure (321a) may have a degree of inclination or curvature corresponding to a portion of a curved surface (e.g., a curved surface facing the z-axis direction or diagonal direction) of a display curved surface area (e.g., a display curved surface area (260_cr) of FIG. 9) of the display assembly (360).

[0100] The second support structure (321b) may be arranged to be spaced apart from the first support structure (321a) by a certain distance in the vertical direction (or z-axis direction, or -z-axis direction). The shape, size, and position of the second support structure (321b) may have at least one of a shape, size, and position that are symmetrical with respect to the first support structure (321a) with respect to a virtual horizontal center line of the structure substrate (310) (e.g., a virtual horizontal center line (1100_L) parallel to the -x-axis or the x-axis, which is a virtual line crossing between the first support structure (321a) and the second support structure (321b). As an example, the second support structure (321b) may include one surface that is formed flat and faces the structure substrate (310), and the other surface that, when mounted on the electronic device (101), faces the display assembly (360) and has a certain inclination or a certain curvature (e.g., a curvature identical to or inherited from a portion of the curvature of the display curved area (260_cr) of FIG. 9). At least one second support groove (e.g., the support groove (320_sh) described above in FIG. 9) into which a pillar portion (332) of the actuator (330) is inserted may be formed on one surface of the second support structure (321b).

[0101] The above plurality of actuators (330) may include a first actuator group arranged in a first row (e.g., a row formed in a direction skewed toward the z-axis with respect to the horizontal center line (1100_L) of the structure substrate (310) and having a plurality of actuators arranged along the x-axis) and coupled to the first support structures (321a), and a second actuator group arranged in a second row (e.g., a row formed in a direction skewed toward the -z-axis with respect to the horizontal center line (1100_L) of the structure substrate (310) and having a plurality of actuators arranged along the x-axis) and coupled to the second support structures (321b). In the first arrangement state, the base portions (331) of the plurality of actuators (330) can be arranged in the -y-axis direction (or in the direction of the first surface of the structure substrate (310) toward the bottom surface of the case groove (210_rc)) with respect to the structure substrate (310). Some of the pillar portions (332) of the plurality of actuators (330) can be positioned in the -y-axis direction with respect to the structure substrate (310), other portions of the pillar portions (332) can be positioned within holes formed in the structure substrate (310), and the remaining portions of the pillar portions (332) can be positioned in the y-axis direction with respect to the structure substrate (310). Correspondingly, a gap of a first size can be formed between the structure substrate (310) and the first support structure (321a) (or between the structure substrate (310) and the second support structure (321b)). In the second arrangement state, the base portions (331) of the plurality of actuators (330) can be arranged in the y-axis direction (or in the display assembly (360) direction) with respect to the structure substrate (310). The pillar portions (332) of the plurality of actuators (330) can be positioned in the y-axis direction with respect to the structure substrate (310). Correspondingly, a gap of a second size larger than the first size can be formed between the structure substrate (310) and the first support structure (321a) (or between the structure substrate (310) and the second support structure (321b)).According to one embodiment, when the second type auxiliary structure (300a) is mounted on the electronic device (101), in the second arrangement state, at least a portion of the first support structure (321a) and the second support structure (321b) may be in contact with one surface of the display assembly (360).

[0102] Meanwhile, in Fig. 11, a form in which two first support structures (321a) and a second support structure (321b) are arranged on a structure substrate (310) is exemplified, but the present disclosure is not limited thereto. For example, the electronic device (101) may include an auxiliary structure in which a plurality of first support structures (321a) are arranged at regular intervals in the -x-axis direction or the x-axis direction in a first row of the structure substrate (310), and a plurality of second support structures (321b) are arranged at regular intervals in a second row. Alternatively, the electronic device (101) may include an auxiliary structure in which a first deformable support structure having the same shape as the first support structure (321a) illustrated in the shape of the z-axis cross-section and having a length corresponding to the length of the structure substrate (310) in the x-axis direction (or at least a portion of the x-axis length of the support structure (320) described above in FIG. 7) is arranged in the first row of the structure substrate (310), and a second deformable support structure having the same shape as the first deformable support structure and having an opposite curved arrangement direction is arranged in the second row. As another example, the first deformable support structure (or the second deformable support structure) may include, for example, a form in which first support structures (321a) (or second support structures (321b)) of a certain size are continuously connected. Alternatively, the electronic device (101) may include a plurality of first support structures (321a) and at least one first deformable support structure, a plurality of second support structures (321b) and at least one second deformable support structure. According to one embodiment, a specific auxiliary structure disposed in the electronic device (101) may include a plurality of individually provided support structures, the first side of which faces the structure substrate having a rectangular (e.g., square) shape of a predetermined size, and the support structures may include a structure in which a grid pattern is arranged on one structure substrate or a plurality of structure substrates.As an example, a structure substrate of a certain size corresponding to the size of one actuator described in FIG. 8 and a support structure of a certain size may be included, and structures of a relatively small size compared to the auxiliary structure described in FIG. 5 may be gathered to form one auxiliary structure. According to one embodiment, the size of one actuator described in FIG. 8 may vary depending on at least one of the size, type, and arrangement of the support structure.

[0103] FIG. 12 is a drawing showing an example of an electronic device including a third type auxiliary structure according to one embodiment.

[0104] Referring to FIGS. 2 to 12, the electronic device (101) may include a display assembly (360), a second housing (420), a first case (210), a third type auxiliary structure (300b1) (or structure, a third type structure), and a fourth type auxiliary structure (300b2) (or structure, a fourth type structure). Additionally or alternatively, as described above with reference to FIG. 4, the electronic device (101) may further include at least some of other components in addition to the above-described components.

[0105] The illustrated drawing state is a drawing showing an example of a first arrangement state in which the third type auxiliary structures (300b1) and the fourth type auxiliary structures (300b2) are spaced apart from the display assembly (360) so that the electronic device (101) can be transformed from the contracted position to the extended position. When the electronic device (101) is placed in a second arrangement state corresponding to the contracted position or the extended position, at least a portion of the third type auxiliary structures (300b1) and the fourth type auxiliary structures (300b2) can form a state in which they are in contact with (or in a state in which they are approached within a predefined first distance) at least a portion of the display assembly (360).

[0106] The third type auxiliary structure (300b1) may include a first structure substrate (310a1), a third support structure (322a), and a first actuator (330g1) (or a first actuator group).

[0107] The width of the first structure substrate (310a1) may be, for example, half the width (or z-axis length) of the structure substrate (310) described above in FIG. 6. Alternatively, the length of the first structure substrate (310a1) in the x-axis direction may be formed to be the same as or similar to the length of the structure substrate (310) in the x-axis direction described in FIG. 6, and the z-axis length of the first structure substrate (310a1) may be formed to be smaller than the z-axis length of the structure substrate (310) described in FIG. 6. The first structure substrate (310a1) may also have, for example, a size on which one first actuator (330g1) can be placed. Alternatively, the first structure substrate (310a1) may have a size that allows a plurality of first actuators (330g1) arranged on the first row (e.g., a first actuator group in which a plurality of actuators are arranged in one row) to be arranged.

[0108] The third support structure (322a) may have at least one of the same or similar sizes and shapes as the second support structure (321b) described above in FIG. 11. The third support structure (322a) may have a curved surface (or curvature) (e.g., a shape in which at least a portion is concave 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 certain curvature and at least a portion is convex in the z-axis direction).

[0109] The first actuator (330g1) may have the same structure as the actuator (330) described above in FIG. 8. According to one embodiment, in the first arrangement state, the first actuator (330g1) has a state in which the base portion (331) is positioned on one side (e.g., one side in the -y-axis direction or one side in the diagonal direction between the -z-axis and the y-axis) with respect to the first structure substrate (310a1), and one part of the pillar portion (332) is positioned on the inside of the base portion (331), and the remaining part may be positioned in a form in which it protrudes by a first length in the other side (e.g., the y-axis direction or the diagonal direction between the -z-axis and the y-axis) with respect to the hole of the structure substrate (310) and the first structure substrate (310a1). The first actuator (330g1) may be transformed into a second arrangement state in response to control by a processor (e.g., processor (120) of FIG. 1) of the electronic device (101). In the second state, the base portion (331) of the first actuator (330g1) may have a state in which it protrudes in a direction other than the first structure substrate (310a1) (e.g., in the y-axis direction or in the diagonal direction between the -z-axis and the y-axis), and the pillar portion (332) may protrude in the direction other than the first length from a point of the base portion (331) 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 be in contact with (or in a state of approaching within a pre-designed distance) a certain portion of the display assembly (360) (e.g., an upper portion (or a portion in the z-axis direction) of the first extension area (263) or a portion of the first extension area (263) arranged close to the first screen area (261).

[0110] The third type auxiliary structure (300b1) described above can be placed in the first structure placement groove (210_h1) formed between the first case lower portion (210_sd3) and the first case upper portion (210_sd4). The electronic device (101) can further include a fixing means so that the third type auxiliary structure (300b1) can be fixed to the first structure placement groove (210_h1). The first structure placement groove (210_h1) can have a shape that is opened in a diagonal direction between the -z axis and the y axis, for example. The drawing shown is an example of a cross-section of one side of the first case (210), and the first structure substrate (310a1) of the third type auxiliary structure (300b1) can be manufactured in a module shape having a substrate shape having a size similar to that of the first actuator (330g1). When the third type auxiliary structure (300b1) is composed of a plurality of modules, they may be arranged at regular intervals inside the first case (210). In this regard, the first structure arrangement groove (210_h1) may include a plurality of grooves arranged at regular intervals inside the first case (210). Wires for electrically connecting each of the third type auxiliary structures (300b1) may be arranged on the inside of the first case (210) of the electronic device (101) (e.g., the bottom surface of the case groove (210_rc) of FIG. 5). Alternatively, the first structure substrate (310a1) may have a length that is the same as or similar to the x-axis length of the structure substrate (310) described in FIG. 6, and the z-axis length may be formed to be a length that is smaller than the z-axis length of the structure substrate (310) of FIG. 6 (e.g., half the size of the structure substrate (310). In this case, wiring connecting the third type auxiliary structures (300b1) on (or within) the first structure substrate (310a1) may be included.When the first structure substrate (310a1) is formed as a single substrate having a length corresponding to the x-axis length of the first case bottom (210_sd3), the first structure placement groove (210_h1) may include a single groove shape into which the first structure substrate (310a1) can be inserted on the inside of the first case bottom (210_sd3).

[0111] The fourth type auxiliary structure (300b2) may include a second structure substrate (310a2), a fourth support structure (322b), and a second actuator (330g2) (or a second actuator group). The fourth type auxiliary structure (300b2) may have a structure identical to or similar to that of the third type auxiliary structure (300b1), and may be arranged at a position symmetrical to that of the third type auxiliary structure (300b1). As an example, the fourth support structure (322b) of the fourth type auxiliary structure (300b2) may be arranged to face a diagonal direction between the z-axis and the y-axis, and may be arranged with at least a portion thereof in the second structure arrangement groove (210_h2) in the first arrangement state, and may be arranged in contact with (or in a state of approaching within a predefined distance) another portion of the display assembly (360) (e.g., a lower portion of the first extension region (263) or a portion of the first extension region (263) arranged close to the second extension region (262)) in the second arrangement state.

[0112] 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) having a first size of length in the x-axis direction and a first number of first structure substrates (310a1), and the fourth type auxiliary structure (300b2) may include a second number of fourth support structures (322b) having a smaller size of length in the x-axis direction and being more than the first number, and a second number of second structure substrates (310a2). Alternatively, the third type auxiliary structure (300b1) may be arranged as a plurality of individual modules within the case groove (210_rc), and the fourth type auxiliary structure (300b2) may include a structure in which one support structure is formed on one structure substrate.

[0113] FIG. 13 is a drawing showing an example of an electronic device including a type 5 auxiliary structure according to one embodiment.

[0114] Referring to FIGS. 2 to 13, an electronic device (101) according to an embodiment may include a display assembly (360), a second housing (420), a first case (210), and a fifth type auxiliary structure (300c) (or structure, a fifth type structure). Additionally or alternatively, the electronic device (101) may further include a third type auxiliary structure (300b1) (or a fourth type auxiliary structure (300b2)). For example, in FIG. 13, an electronic device (101) including both a third type auxiliary structure (300b1) and a fifth type auxiliary structure (300c) is illustrated, but the electronic device (101) may also include only a fifth type auxiliary structure (300c). The third type auxiliary structure (300b1) and the first structure arrangement groove (210_h1) may have the same or similar shape as the third type auxiliary structure and the first structure arrangement groove described above in FIG. 12.

[0115] The fifth type auxiliary structure (300c) may include a third structure substrate (310a3), a fifth support structure (322c), and a third actuator (330g3) (or a first actuator group).

[0116] The third structure substrate (310a3) may have a size smaller than, for example, the structure substrate (310) described in FIG. 6 and larger than the first structure substrate (310a1) described in FIG. 12. For example, the third structure substrate (310a3) may be formed to have a size equal to or greater than half of the z-axis height of the inner groove of the first case (210). Alternatively, the third structure substrate (310a3) may be formed to have a z-axis length corresponding to or greater than half of the z-axis height of the display assembly (360). The fifth type auxiliary structure (300c) may be formed as a single structure or may be arranged in multiple numbers inside the first case (210). Correspondingly, the third structure substrate (310a2) may include one substrate arranged in the inner side of the first case (210) or may include multiple substrates arranged at a predetermined interval. The third structure substrate (310a2) may include wiring for supplying power to the third actuator (330g3) and a hole for placing the third actuator (330g3).

[0117] The fifth support structure (322c) may be formed to have a z-axis length that is smaller than the z-axis length of the support structure (320) described in FIG. 7 and to have a z-axis length that is larger than the z-axis length of the first support structure (321a) described in FIG. 11 or the third support structure (322a) described in FIG. 12. As an example, the size of one side of the fifth support structure (322c) in the -y-axis direction may be the same as or similar to the size of one side of the third structure substrate (310a2) within a certain error range. According to an embodiment, the z-axis height of the fifth support structure (322c) may be formed to have a size that is half or more of the z-axis height of the inner groove of the first case (210). Alternatively, the z-axis height of the fifth support structure (322c) may be formed to have a height that is half or more of the z-axis height of the display assembly (360).

[0118] The third actuator (330g3) may have the same size and structure as the actuator described in FIG. 11 or FIG. 12. Alternatively, the third actuator (330g3) may include a base portion (331a) and a pillar portion (332a) that are larger than the base portion and the pillar portion of the actuator described in FIG. 11 or FIG. 12. The pillar portion (332a) may be inserted into a support groove (320_sh) formed on the rear surface of the fifth support structure (322c). The support groove (320_sh) may be formed at a center of gravity position on the rear surface of the fifth support structure (322c). As an example, the actuator may have a different size depending on at least one of the size, position, and direction of the support structure.

[0119] According to one embodiment, in the first arrangement state, at least a portion of the fifth support structure (322c) may be arranged within the third structure arrangement groove (210_h3) to form a gap of a first size with one surface of the third structure substrate (310a2). In the second arrangement state, at least a portion of the fifth support structure (322c) may protrude in the y-axis direction into the third structure arrangement groove (210_h3) to form a gap of a second size larger than the first size with one surface of the third structure substrate (310a2). Alternatively, in the second arrangement state, at least a portion of the fifth support structure (322c) may be in contact with a portion of the display assembly (360) (e.g., the first extension region (263)) or may have a state in which it approaches within a predefined distance. The fifth type auxiliary structure (300c) may move linearly in a direction parallel to the first case bottom portion (210_bt). In this regard, the third structure arrangement groove (210_h3) may be formed to be engraved in the -y-axis direction on the inside of the first case (210). In the second arrangement state and the contracted position state, the fifth support structure (322c) is arranged to support more than half of the first extension area (263) (or the display curved area) of the display assembly (360), thereby preventing damage to the display assembly (360) when an external impact occurs. In the second arrangement state and the extended position state, the fifth support structure (322c) supports more than half of the second extension area (262) (or the display curved area corresponding to the curved area (421) of the second housing (420), thereby preventing damage to the display assembly (360). The electronic device (101) may support an intermediate state between the maximum contracted position and the maximum extended position.In response to this, when the electronic device (101) is temporarily fixed in an intermediate state, the fifth support structure (322c) can come into contact with a specific area of ​​the display assembly (360) (e.g., a display curved area corresponding to the intermediate state) to prevent damage to the specific area of ​​the display assembly (360).

[0120] Meanwhile, in the above-described structure, the third type auxiliary structure (300b1) is arranged between the first case bottom (210_sd3) and the first case top (210_sd4), and the fifth type auxiliary structure (300c) is arranged on one side of the first case bottom (210_sd3), but the present disclosure is not limited thereto. For example, the fifth type auxiliary structure (300c) may be arranged at a position that is biased toward the first case top (210_sd4) among the first case bottom (210_sd3). In this case, the fifth support structure may be arranged in a direction opposite to the curved area arrangement direction of the fifth support structure (322c) of the fifth type auxiliary structure (300c) currently illustrated. For example, the fifth type auxiliary structure (300c) may be arranged at a position symmetrical in the up-down (or z~-z axis) direction based on the virtual horizontal center line (cen_line) of the display assembly (360). Correspondingly, at least a part of the fifth support structure (322c) is arranged close to the first case top (210_sd4), and in the second arrangement state, the fifth support structure (322c) can block the gap between the first case top (210_sd4) and the display assembly (360).

[0121] The drawing shown is an example of a cross-section of one side of the first case (210), and the third structure substrate (310a2) of the fifth type auxiliary structure (300c) may be manufactured in a module form having a substrate shape similar in size to the size of the third actuator (330g3). The fifth type auxiliary structure (300c) may be composed of a plurality of modules, and correspondingly, the third structure arrangement groove (210_h3) may include a plurality of grooves that are arranged at regular intervals inside the first case (210). Wires that electrically connect each of the fifth type auxiliary structures (300c) may be arranged inside the first case (210) of the electronic device (101) (e.g., the bottom surface of the case groove (210_rc) of FIG. 5). Alternatively, the fifth type auxiliary structure (300c) may include a third structure substrate (310a2) having a length corresponding to the x-axis length of the first case bottom (210_sd3), and may include a plurality of third actuators (330g3) and one fifth support structure (322c).

[0122] Meanwhile, the examples of auxiliary structures described in the above-described FIGS. 2 to 13 each have an independent structure and can be applied to the electronic device (101), but the present disclosure is not limited thereto. For example, at least some features of the auxiliary structures (e.g., 300) described in FIGS. 2 to 10 can be selectively applied to at least some of the auxiliary structures (300a, 300b1, 300b2, 300c) described in FIGS. 11 to 13. Alternatively, various forms of the auxiliary structures (300a, 300b1, 300b2, 300c) described in FIGS. 11 to 13 can be fused with each other. For example, at least one of the auxiliary structures (300a, 300b1, 300b2, 300c) of the present disclosure may include a structure in which one actuator is disposed on a separate structure substrate, or a structure in which a plurality of actuators are disposed on a single structure substrate. In addition, the shape of the support structure included in the auxiliary structures (300a, 300b1, 300b2, 300c) of the present disclosure may also be provided in a shape that is separated to correspond to the size of one actuator, or in a shape that has one body that can receive support from a plurality of actuators. As an example, the support structure may be provided in a grid shape divided vertically and horizontally, and at least one grid shape that can be applied to one electronic device (101) may be included. For example, support structures having different grid shapes (e.g., at least one of the support structures described in FIGS. 11 to 13) may be applied to one electronic device (101).

[0123] FIG. 14 is a drawing showing an example of a first printed circuit board connected to an auxiliary structure according to one embodiment. In FIG. 14, the state 1401 is a drawing showing an example of a form in which the first printed circuit board (1300) and the first case (210) are separated, and the state 1403 is a drawing showing an example of a form in which the first printed circuit board (1300) is arranged on the back surface of the first case (210) (e.g., the back surface of the first case bottom portion (210_bt)). The state 1405 is a drawing showing an example of a portion of the first printed circuit board (1300) arranged on the first case (210), and the state 1407 is a drawing showing an example of a cross-section cut along the A3-A3` cutting line in the state 1405. Although FIG. 14 illustrates a structure to which the first type auxiliary structure (300) is applied, the present disclosure is not limited thereto. For example, the same may be applied to other types of auxiliary structures described in FIGS. 11 to 13 above, and in this regard, at least one of the structure substrates described in FIGS. 11 to 13 may include a structure corresponding to the substrate connecting portion (311).

[0124] Referring to FIGS. 2 to 14, the first case (210) may include a first case bottom portion (210_bt), a first case right portion (210_sd1), a first case left portion (210_sd2), a first case bottom portion (210_sd3), and a first case top portion (210_sd4). The first printed circuit board (1300) may include, for example, a first PCB portion (1300a) formed such that a length in a first direction (e.g., y-axis direction) is longer than a length in a second direction (e.g., x-axis direction), and a second PCB portion (1300b) connected to the first PCB portion (1300a) and formed such that a length in the second direction is longer than a length in the first direction. A PCB terminal (1300e) that can be electrically connected to a first type auxiliary structure (300) can be arranged on one portion of the second PCB portion (1300b). The PCB terminal (1300e) can be arranged, for example, on one surface of the second PCB portion (1300b) in a direction facing the front of the first case bottom portion (210_bt), and can be arranged at a position that can face the substrate connection portion (311) of the first type auxiliary structure (300). In the illustrated drawing, the PCB terminal (1300e) is exemplified as having two terminals in a C-clip shape, but the embodiment of the present disclosure is not limited to the number or shape of the PCB terminal (1300e). Referring to a cross-section cut along the A3-A3` cutting line of the 1405 state, the first type auxiliary structure (300) includes a structure substrate (310) and a support structure (320), and referring to the auxiliary structures described above in FIGS. 2 to 13, the first type auxiliary structure (300) may include at least one actuator. In addition, the first type auxiliary structure (300) may further include a fixing means (310_ad) (e.g., a bonding member, an adhesive member, an adhesive layer) for fixing the structure substrate (310) to the lower part of the first case (210_sd3).

[0125] The first printed circuit board (1300) may be mounted (or adhered, fixed, or placed) on the back surface (e.g., the surface observed in the -z-axis direction) of the first case bottom portion (210_bt). At least a portion of the first case bottom portion (210_bt) may include at least one hole (e.g., 210_bth) penetrating the front and back surfaces (e.g., the surface in the z-axis or -z-axis direction), and through the at least one hole (e.g., 210_bth), at least a portion of the first printed circuit board (1300) may be placed on the front surface (e.g., the surface observed in the z-axis direction) of the first case bottom portion (210_bt). As an example, a part of the first printed circuit board (1300) may be exposed to the front surface of the first case bottom portion (210_bt) through a hole (210_bth) formed in the first case bottom portion (210_bt), and the part of the first printed circuit board (1300) exposed to the front surface may be in electrical contact with a part of the second printed circuit board (1500). Similarly, at least a part of the substrate connection portion (311) of the first type auxiliary structure (300) may be exposed toward the back surface (e.g., the surface facing the -z-axis direction) of the first case bottom portion (210_bt) through the hole formed in the first case bottom portion (210_bt). The PCB terminal (1300e) may be electrically connected to a terminal (311_t) formed in the substrate connection portion (311) of the first type auxiliary structure (300). The number of terminals (311_t) formed on the above substrate connection portion (311) may be formed to be the same as or similar to the number of terminals formed on the above PCB terminal (1300e).

[0126] The first printed circuit board (1300) above can receive power from a battery (e.g., battery (205) of FIG. 4) and transmit the supplied power to a terminal (311_t) of a board connection portion (311) through a PCB terminal (1300e). The power transmitted through the terminal (311_t) of the board connection portion (311) can be supplied to a plurality of actuators (e.g., a plurality of actuators (330) of FIG. 5) through wiring arranged on the structure board (310). When power is supplied, the first type auxiliary structure (300) can move the support structure (320) in a first direction to adjust the gap between the support structure (320) and the structure substrate (310) to a first size, and when power is cut off, the first type auxiliary structure (300) can move the support structure (320) in a second direction opposite to the first direction to adjust the gap between the structure 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 structure substrate (310) in a power-on or power-off state may vary depending on the design. As an example, when the power supply is cut off, the gap between the support structure (320) and the structure substrate (310) may be a first size (or a minimum size that the first type auxiliary structure (300) can form), and when the power supply is supplied, the gap between the support structure (320) and the structure substrate (310) may be a second size (or a maximum size that the first type auxiliary structure (300) can form).Alternatively, when the power supply is cut off, the gap between the display assembly (e.g., the display assembly (360) of FIG. 4) of the electronic device (101) and the support structure (320) may become the second size (or the maximum size that the first type auxiliary structure (300) can form), and when the power is supplied, the gap between the display assembly (e.g., the display assembly (360) of FIG. 4) and the support structure (320) may become the first size (or the minimum size that the first type auxiliary structure (300) can form, or a contact state in which the gap is 0).

[0127] Fig. 15 is a drawing showing an example of a connection relationship between a first printed circuit board and other printed circuit boards according to one embodiment. In Fig. 15, state 1501 shows an example of a form in which the first case (210), the first housing (410), and the second housing (420) are separated, and state 1503 shows an example of a form in which the first case (210), the first housing (410), and the second housing (420) are combined.

[0128] Referring to FIGS. 2 to 15, the electronic device (101) may include a first case (210), a first housing (410), a second housing (420), a first printed circuit board (1300), a second printed circuit board (1500), and a third printed circuit board (1400). The second housing (420) may be placed on a rear surface of the first housing (410), and the first case (210) may be arranged to cover at least a portion of the second housing (420). The first case (210) and the second housing (420) may move linearly in a first direction or a second direction (e.g., in the -y-axis direction or the y-axis direction), and correspondingly, the first case (210) may move linearly in the first direction or the second direction. Depending on the observation point, the first case (210) and the second housing (420) are fixed, and the first housing (410) may move linearly in the second direction or the first direction (e.g., the y-axis direction or the -y-axis direction).

[0129] As described above in FIG. 14, the first printed circuit board (1300) connected to the auxiliary structure (e.g., the first type auxiliary structure (300)) may be at least partially disposed on the back surface (e.g., the surface observed from the -z axis) of the first case (210). The first case (210) may include at least one hole used to connect at least a portion of the first printed circuit board (1300) with other structures. For example, the first type auxiliary structure (300) may be disposed within the first case (210), and the substrate connection portion (311) of the structure substrate (310) of the first type auxiliary structure (300) may be electrically connected to the PCB terminal (1300e) of the first printed circuit board (1300). The end extending in the y-axis direction of the first printed circuit board (1300) may include a connection structure that can be connected to the second printed circuit board (1500). For example, one edge of the first printed circuit board (1300) may include at least one first connector arranged toward the z-axis direction.

[0130] The second printed circuit board (1500) (or connecting printed circuit board) may include a first portion (1500a) disposed on one side of the back surface (e.g., the surface facing the -z-axis direction) of the second housing (420), 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 fixed on the second housing (420). The first portion (1500a) may be electrically coupled to, for example, the first printed circuit board (1300). According to one embodiment, the first portion (1500a) may include a second connector disposed toward the -z-axis direction, and may be electrically connected to a first connector formed at an end of a portion extending toward the y-axis edge of the first printed circuit board (1300). The second part (1500b) may be configured to be electrically connected to the first part (1500a) and to have at least a portion of its arrangement changed according to the movement of the second housing (420). For example, at least a portion of the second part (1500b) may include a wrinkled or folded shape. At least a portion of the second part (1500b) may be arranged to unfold when the second housing (420) moves in the -y-axis direction and to fold when the second housing (420) moves in the y-axis direction. For example, at least a portion of the second part (1500b) may be formed of a flexible material. Alternatively, a portion of the second part (1500b) may be formed of a rigid type, and a portion that is bent may be formed of a flexible type. Another part of the second portion (1500b) may be electrically connected to a third printed circuit board (1400) (or main printed circuit board). In this regard, a third connector may be arranged at one end of the second portion (1500b), and the third connector arranged on the second portion (1500b) may be electrically connected to a fourth connector arranged on the third printed circuit board (1400).

[0131] An electronic device (101) having the above-described structure receives power from a battery (205) through a third printed circuit board (1400), and in response to the control of a processor disposed on the third printed circuit board (1400), the received power from the battery (205) can be transmitted to a first type auxiliary structure (300) through the third printed circuit board (1400), the second printed circuit board (1500), and the first printed circuit board (1300).

[0132] FIG. 16 is a diagram showing a first state related to sliding detection of an electronic device according to one embodiment, and FIG. 17 is a diagram showing a second state related to sliding detection of an electronic device according to one embodiment.

[0133] Referring to FIGS. 2 to 17, the 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) so as to be movable in the y-axis or -y-axis direction. For example, as shown in FIG. 16, the electronic device (101) may have a first state in which the size (415_sp1) of the overlapping area between the first housing (410) and the second housing (420) (or the length (415_L1) of one overlapping side between the first housing (410) and the second housing (420)) is a first size when observed in the z-axis direction (or -z-axis direction), and a second state in which the size (415_sp2) of the overlapping area between the first housing (410) and the second housing (420) (or the length (415_L2) of one overlapping side between the first housing (410) and the second housing (420)) is a second size greater than the first size when observed in the z-axis direction (or -z-axis direction), as shown in FIG. 17. In the first state, a certain range of the -y-axis edge of the first housing (410) and a certain range of the y-axis edge of the second housing (420) can be arranged to overlap with respect to the z-axis direction. In the first state, a certain range including the center of the first housing (410) and a certain range including the center of the second housing (420) can be arranged to overlap with respect to the z-axis direction.

[0134] At least a portion of a fourth printed circuit board (1600) may be placed on one surface (e.g., a surface facing the -z axis) of the first housing (410). 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)) may detect a change in magnetic flux of the magnet member (420_mg). As an example, a plurality of sensors (1600_sr) can sense a change in magnetic flux when a magnet member (420_mg) approaches or moves away from the magnet member (420_mg). The plurality of sensors (1600_sr) can transmit the sensed change in magnetic flux to the third printed circuit board (1400) through a wiring formed in the board body (1600_bd). Meanwhile, as illustrated, a magnet member (420_mg) may be arranged on one side of the second housing (420) (e.g., one side of the side wall in the -x-axis direction). The relative position of the magnet member (420_mg) in the first housing (410) may change depending on the movement of the second housing (420). For example, as the second housing (420) moves, the magnet member (420_mg) moves, and as the magnet member (420_mg) moves, a plurality of sensors (1600_sr) arranged on the fourth printed circuit board (1600) can detect a change in magnetic flux according to the movement of the magnet member (420_mg) and transmit it to the third printed circuit board (e.g., the third printed circuit board (1400) of FIG. 15).

[0135] The processor disposed on the third printed circuit board (e.g., the third printed circuit board (1400) of FIG. 15) can determine the current state of the electronic device (101) based on the transmitted magnetic flux change. For example, when receiving a magnetic flux change indicating that the magnet member (420_mg) is disposed at the -y-axis edge of the fourth printed circuit board (1600) from a plurality of sensors (1600_sr), the processor can determine whether the state of the electronic device (101) is an extended position state as illustrated in FIG. 16 or a retracted position state as illustrated in FIG. 17. Additionally or alternatively, the processor can detect that the state of the electronic device (101) changes from the retracted position to the extended position state or from the extended position state to the retracted position state through the magnetic flux change provided by the plurality of sensors (1600_sr). For example, if a change occurs in the magnetic flux detected by a sensor positioned at the y-axis edge of the fourth printed circuit board (1600), the processor may determine that the state has changed from a retracted position state to an extended position state. Alternatively, if a change occurs in the magnetic flux detected by a sensor positioned at the -y-axis edge of the fourth printed circuit board (1600), the processor may determine that the state has changed from an extended position state to a retracted position state.

[0136] The arrangement of printed circuit boards related to power supply described in FIGS. 14 and 15 can be applied to an electronic device to which at least one of the auxiliary structures described in FIGS. 2 to 13 is applied. Similarly, the detection, contraction, or extension position state detection function related to a state change of the electronic device (101) described in FIGS. 16 to 17 can be applied identically or similarly to an electronic device to which at least one of the auxiliary structures described in FIGS. 2 to 13 is applied. In addition, the state detection of the electronic device can be equally applied even in the arrangement environment of the printed circuit boards applied in FIGS. 14 and 15.
