For example, if the electronic device (101) includes a main processor (121) and a secondary processor (123), the secondary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a specified function. The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0037] The auxiliary processor (123) may control at least a part of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)).

[0040] The input module (150) can receive commands or data to be used in a component of the electronic device (101) (e.g., a processor (120)) from an external source (e.g., a user) of the electronic device (101). The input module (150) can include, for example, a microphone, a mouse, a keyboard, a key (e.g., a button), or a digital pen (e.g., a stylus pen).

[0041] The audio output module (155) can output audio signals to the outside of the electronic device (101). The audio output module (155) can include, for example, a speaker or a receiver. The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. According to one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0042] The display module (160) can visually provide information to an external party (e.g., a user) of the electronic device (101). The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. According to one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0043] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), output sound through the sound output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0044] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0045] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) with an external electronic device (e.g., the electronic device (102)). In one embodiment, the interface (177) may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0046] The connection terminal (178) may include a connector through which the electronic device (101) may be physically connected to an external electronic device (e.g., electronic device (102)). According to one embodiment, the connection terminal (178) may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0047] A haptic module (179) can convert electrical signals into mechanical stimuli (e.g., vibration or movement) or electrical stimuli that a user can perceive through tactile or kinesthetic sensations. According to one embodiment, the haptic module (179) can include, for example, a motor, a piezoelectric element, or an electrical stimulation device.

[0048] The camera module (180) can capture still images and videos. According to one embodiment, the camera module (180) may include one or more lenses, image sensors, image signal processors, or flashes.

[0049] The power management module (188) can manage power supplied to the electronic device (101). According to one embodiment, the power management module (188) can be implemented as, for example, at least a part of a power management integrated circuit (PMIC).

[0050] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0051] 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, Wi-Fi (wireless fidelity) direct, or IrDA (infrared data association)) 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).

[0052] 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)). According to one embodiment, the wireless communication module (192) may support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0053] 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 by, for example, 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. According to some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0054] According to various embodiments, the antenna module (197) may form a mmWave antenna module. According to 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.

[0055] 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)).

[0056] 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). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. 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.

[0057] FIG. 2A is a top plan view of an exemplary electronic device in a first state, according to one embodiment. Referring to FIG. 2A, an electronic device (200) (e.g., the electronic device (101) of FIG. 1) may include a housing and a display (230) (e.g., the display module (160) of FIG. 1) at least partially housed within the housing. For example, the display (230) may be flexible. For example, the display (230) may provide at least a portion of an outer surface of the electronic device (200) and may include an area (or display area) that is visually exposed outside the housing of the electronic device (200). For example, because the display (230) has flexibility, at least a portion of the display (230) may be rollable into the housing or slidable into the housing. For example, the size of the area (or display area) of the display (230) visible from the outside may vary depending on the size of at least a portion of the display (230) that is rolled or slid into the housing. For example, the electronic device (200) including the display (230) may be in a plurality of states, including a first state providing the display area having a first size and a second state providing the display area having a second size different from the first size. For example, the first state may be exemplified through the description of FIGS. 2A and 2B. For example, the second state may be exemplified through the description of FIGS. 2C and 2D.

[0058] In one embodiment, the electronic device (200) may include a first housing part (210), a second housing part (220) that is movable relative to the first housing part (210) in a first direction (261) parallel to the y-axis or a second direction (262) parallel to the y-axis and opposite to the first direction (261). Although the second housing part (220) is described as being movable relative to the first housing part (210), this is not limited thereto. For example, the first housing part (210) may be movable relative to the second housing part (220). For example, depending on a change in the relative positional relationship between the first housing part (210) and the second housing part (220), the size of an area (or display area) of the display (230) that is visually exposed outside the housing of the electronic device (200) may change.

[0059] For example, within the first state, the second housing part (220) may be movable relative to the first housing part (210) in a first direction (261) among the first direction (261) and the second direction (262). For example, within the first state, the second housing part (220) may not be movable relative to the first housing part (210) in the second direction (262).

[0060] For example, within the first state, the display (230) may provide the display area having the smallest size. For example, within the first state, the display area may correspond to the first area (230a). For example, although not illustrated in FIG. 2A, within the first state, an area of ​​the display (230) other than the first area (230a) that is the display area (e.g., the second area (230b) of FIG. 2C) may be disposed within the first housing part (210). For example, within the first state, the second area (230b) may be covered by the first housing part (210). For example, within the first state, the second area (230b) may be moved into the first housing part (210). For example, at least a portion of the second area (230b) may be rolled into the first housing part (210). For example, within the first state, the first region (230a) may include a planar portion. For example, within the first state, a portion of the second region (230b) may include a curved portion. However, this is not limited thereto. For example, the first region (230a) may also include a curved portion extending from the planar portion within the first state.

[0061] For example, the first state may be referred to as a slide-in state in that at least a portion of the second housing part (220) is positioned within the first housing part (210) according to the second housing part (220) sliding toward the first housing part (210). For example, the first state may be referred to as a reduced state in that it provides the display area having the smallest size, but is not limited thereto.

[0062] For example, the second housing part (220) may include a front camera (250-1) that obtains visual information through a portion of the first region (230a) and faces a third direction (263) parallel to the z-axis. For example, although not illustrated in FIG. 2A, the second housing part (220) may include one or more rear cameras (e.g., rear cameras (250-2) of FIG. 2B) that are visually exposed through a portion of the second housing part (220) and face a fourth direction (264) parallel to the z-axis and opposite to the third direction (263). For example, the one or more rear cameras (250-2) may be exemplified through the description of FIG. 2B.

[0063] FIG. 2b is a bottom view of an exemplary electronic device in a first state, according to one embodiment.

[0064] Referring to FIG. 2B, within the first state, one or more rear cameras (250-2) disposed within the second housing part (220) may be positioned within a structure disposed within the first housing part (210) for the one or more rear cameras (250-2). For example, since the one or more rear cameras (250-2) are positioned within the structure within the first state, the one or more rear cameras (250-2) may be visually exposed through the structure within the first state. The one or more rear cameras (250-2) may obtain visual information through the structure. For example, the structure may be implemented in various ways. For example, the structure may be an opening or a notch. For example, the structure may be an opening (212a) within a first plate (212) of the first housing part (210) that surrounds at least a portion of the second housing part (220). However, it is not limited to this.

[0065] Referring again to FIG. 1, the first state can be changed to the second state.

[0066] For example, the first state (or the second state) can be changed to the second state (or the first state) through one or more intermediate states between the first state and the second state.

[0067] For example, the first state (or the second state) may be changed to the second state (or the first state) based on a defined user input. For example, the first state (or the second state) may be changed to the second state (or the first state) in response to a user input on a physical button visually exposed through a part of the first housing part (210) or a part of the second housing part (220). There is no limitation on the type of the user input. For example, the user input may include a user input through a touch screen within a display area of ​​the display (230) or a user input through a microphone of the electronic device (200). For example, the state of the electronic device (200) may be changed to the second state (or the first state) by an external force applied to the first housing part (210) and / or the second housing part (220). The second state can be illustrated through the description of FIGS. 2c and 2d.

[0068] FIG. 2c is a plan view of an exemplary electronic device (200) in a second state, according to one embodiment.

[0069] Referring to FIG. 2C, within the second state, the second housing part (220) may be movable relative to the first housing part (210) in the second direction (262) among the first direction (261) and the second direction (262). For example, within the second state, the second housing part (220) may not be movable relative to the first housing part (210) in the first direction (261).

[0070] For example, within the second state, the display (230) may provide the display area having the largest size. For example, within the second state, the display area may correspond to an area (230c) including a first area (230a) and a second area (230b). For example, the second area (230b), which was included within the first housing part (210) within the first state, may be visually exposed within the second state. For example, within the second state, the first area (230a) and the second area (230b) may include a planar portion. However, the present invention is not limited thereto. For example, the first area (230a) and / or the second area (230b) may also include a curved portion extending from the planar portion and positioned within the edge portion.

[0071] For example, the second state may be referred to as a slide-out state in that at least a portion of the second housing part (220) is positioned outside the first housing part (210) according to the second housing part (220) sliding from the first housing part (210). For example, the second state may be referred to as an expanded state in that it provides the display area having the largest size. However, the present invention is not limited thereto.

[0072] For example, the front camera (250-1) facing the third direction (263) may move together with the first region (230a) according to the movement of the second housing part (220) in the first direction (261) when the state of the electronic device (200) changes from the first state to the second state. For example, although not shown in FIG. 2c, one or more rear cameras facing the fourth direction (264) (e.g., the rear cameras (250-2) of FIG. 2d) may move together with the second housing part (220) according to the movement of the second housing part (220) in the first direction (261) when the state of the electronic device (200) changes from the first state to the second state. For example, the relative positional relationship between one or more rear cameras (250-2) and the structure illustrated in the description of FIG. 2B may change according to the movement of one or more rear cameras (250-2). For example, the change in the relative positional relationship may be illustrated in FIG. 2D.

[0073] FIG. 2d is a bottom view of an exemplary electronic device (200) in a second state, according to one embodiment.

[0074] Referring to FIG. 2D, within the second state, one or more rear cameras (250-2) may be positioned outside the structure. For example, within the second state, one or more rear cameras (250-2) may be positioned outside the opening (212a) in the first plate (212). For example, since one or more rear cameras (250-2) are positioned outside the opening (212a) within the second state, one or more rear cameras (250-2) may be visually exposed within the second state. One or more rear cameras (250-2) positioned outside the structure may acquire visual information. For example, since one or more rear cameras (250-2) are positioned outside the structure within the second state, the relative positional relationship between the one or more rear cameras (250-2) and the structure (e.g., the opening (212a)) within the second state may be different from the relative positional relationship between the one or more rear cameras (250-2) and the structure (e.g., the opening (212a)) within the first state (e.g., FIG. 2b).

[0075] Although not shown in FIGS. 2A, 2B, 2C, and 2D, the electronic device (200) may be in an intermediate state between the first state and the second state. For example, the size of the display area in the intermediate state may be larger than the size of the display area in the first state and smaller than the size of the display area in the second state. For example, the display area in the intermediate state may correspond to an area including a portion of the first region (230a) and the second region (230b). For example, in the intermediate state, a portion of the second region (230b) may be visually exposed, and another portion (or a remaining portion) of the second region (230b) may be covered by the first housing part (210) or moved into the first housing part (210). However, the present invention is not limited thereto.

[0076] The electronic device (200) may include structures for moving a second housing part (e.g., the second housing part (220) of FIGS. 2a, 2b, 2c, and 2d) of the electronic device (200) relative to a first housing part (e.g., the first housing part (210) of FIGS. 2a, 2b, 2c, and 2d) of the electronic device (200). For example, the structures may be exemplified through the description of FIGS. 3a and 3b.

[0077] In this disclosure, descriptions of components having the same reference numerals may be applied in the same or corresponding manner, even when referring to different drawings, unless otherwise specified. Furthermore, overlapping descriptions of components having the same reference numerals may not be repeated.

[0078] Figures 3a and 3b are exploded perspective views of an exemplary electronic device.

[0079] Referring to FIGS. 3A and 3B, the electronic device (200) may include a first housing part (210), a second housing part (220), a display (230), and a driving unit (360).

[0080] In one embodiment, the first housing part (210) may include a first cover (311), a first plate (212), and a frame (313).

[0081] For example, the first cover (311) may at least partially form a side portion of the outer surface of the electronic device (200). For example, the first cover (311) may at least partially form a rear portion of the outer surface. For example, the first cover (311) may include an opening (311a) for one or more rear cameras (250-2). For example, the first cover (311) may include a surface that supports the first plate (212). For example, the first cover (311) may be coupled with the first plate (212). For example, the first cover (311) may provide a space in which the frame (313) is mounted. For example, the first cover (311) may be coupled with the frame (313).

[0082] For example, the first plate (212) may at least partially form a rear portion of the outer surface. For example, the first plate (212) may include an opening (212a) for one or more rear cameras (250-2). For example, the first plate (212) may be disposed on the surface of the first cover (311). For example, the opening (212a) may be aligned with the opening (311a).

[0083] For example, the frame (313) may be at least partially surrounded by the first cover (311). For example, the frame (313) may be at least partially surrounded by the display (230). For example, although the frame (313) is at least partially surrounded by the display (230), the position of the frame (313) may be maintained independently of the movement of the display (230). For example, the frame (313) may be arranged with respect to at least some of the components of the display (230). For example, the frame (313) may include rails (313a) that provide (or guide) a path for movement of at least one component of the display (230).

[0084] For example, the frame (313) may be coupled with at least one component of the electronic device (200). For example, the frame (313) may support a rechargeable battery (319). For example, the battery (319) may be supported through a recess or hole in a surface (313b) of the frame (313). For example, the frame (313) may secure one end of a flexible printed circuit board (FPCB) (325) on the surface of the frame (313). One end of the FPCB (325) may be electrically connected to the motor structure (361). For example, although not explicitly shown in FIGS. 3A and 3B , the other end of the FPCB (325) may be connected to the PCB (324) through at least one connector. For example, the PCB (324) may be electrically connected to another PCB (not shown in FIGS. 3a and 3b) that supplies power to the motor structure (361) via the FPCB (325).

[0085] For example, the frame (313) can be coupled with at least one structure of the electronic device (200) for a plurality of states including the first state and the second state. For example, the frame (313) can fasten the rack gear (363) of the driving unit (360).

[0086] For example, the second housing part (220) may movably engage with the first housing part (210). The second housing part (220) may include a second cover (321) and a second plate (322).

[0087] For example, the second cover (321) may be at least partially wrapped by the display (230). For example, the second cover (321) may be coupled to at least a portion of the first region (230a) of the display (230) that wraps the second cover (321), unlike the frame (313), such that the display (230) moves along the second housing part (220) relative to the first housing part (210).

[0088] For example, the second cover (321) may be coupled with at least one component of the electronic device (200). For example, the second cover (321) may be coupled with a printed circuit board (PCB) (324) including components of the electronic device (200). For example, the PCB (324) may include a processor (120) (not shown in FIGS. 3A and 3B). For example, the second cover (321) may be coupled with one or more rear cameras (250-2).

[0089] For example, the second cover (321) may be combined with at least one structure of the electronic device (200) for a plurality of states including the first state and the second state. For example, the second cover (321) may fix the motor structure (361) of the driving unit (360). The second cover (321) may be referred to as a bracket of the second housing part (220).

[0090] For example, the motor structure (361) of the driving unit (360) can be fixed to the second cover (321), and the rack gear (363) of the driving unit (360) can be fixed to the frame (313).

[0091] For example, the second cover (321) can be coupled with the second plate (322). For example, the second plate (322) can be coupled with the second cover (321) to protect at least one component of the electronic device (200) coupled within the second cover (321) and / or at least one structure of the electronic device (200) coupled within the second cover (321). For example, the second plate (322) can include a structure for the at least one component. For example, the second plate (322) can include one or more openings (327, 328) for one or more rear cameras (250-2). For example, the one or more openings (327, 328) can be aligned with one or more rear cameras (250-2) disposed on the second cover (321). For example, the size of each of one or more apertures (327, 328) may correspond to the size of each of one or more rear cameras (250-2).

[0092] For example, the display (230) may include a support member (331). For example, the support member (331) may include a plurality of bars. For example, the plurality of bars may be coupled to each other. The support member (331) may support a second region (230b) of the display (230).

[0093] For example, the driving unit (360) may include a motor structure (361), a pinion gear (362), and a rack gear (363). For example, the motor structure (361) may operate based on power from the battery (319). For example, the power may be provided to the motor structure (361) in response to the user input defined above. The motor structure (361) may provide torque for sliding the first housing part (210) and the second housing part (220). Due to the operation of the motor structure (361), vibration may be transmitted to the second housing part (220). The vibration transmitted to the second housing part (220) may be amplified by the second housing part (220), which may generate unpleasant noise. According to one embodiment, the second housing part (220) may include a wall structure that can reduce or prevent noise caused by transmitted vibration by avoiding resonance due to the driving frequency of the motor structure (361). The wall structure is described below with reference to FIGS. 5A to 13.

[0094] For example, the pinion gear (362) can be coupled to the motor structure (361) via a shaft. For example, the pinion gear (362) can be rotated based on the motion of the motor structure (361) transmitted via the shaft.

[0095] For example, the rack gear (363) can be arranged relative to the pinion gear (362). For example, teeth of the rack gear (363) can mesh with teeth of the pinion gear (362). For example, the rack gear (363) can move in a first direction (261) or a second direction (262) according to the rotation of the pinion gear (362). The second housing part (220) can move in the first direction (261) or the second direction (262) according to the movement of the rack gear (363) fixedly coupled to the first housing part (210). For example, the first state of the electronic device (200) can be changed to a state different from the first state (e.g., one or more intermediate states or the second state) through the movement of the second housing part (220) in the first direction (261). For example, the second state of the electronic device (200) can be changed to a state other than the second state (e.g., one or more intermediate states or the first state) through the movement of the second housing part (220) in the second direction (262). For example, the first state being changed to the second state by the driving unit (360) and the second state being changed to the first state by the driving unit (360) can be exemplified through FIGS. 4A and 4B.

[0096] Fig. 4a is a cross-sectional view of an exemplary electronic device in a first state. Fig. 4b is a cross-sectional view of an exemplary electronic device in a second state.

[0097] Referring to FIGS. 4A and 4B, the motor structure (361) can be operated based at least in part on the defined user input received within the first state (490). For example, the pinion gear (362) can be rotated in the first rotational direction (411) based at least in part on the operation of the motor structure (361). For example, the rack gear (363) can be moved in the first direction (261) based at least in part on the rotation of the pinion gear (362) in the first rotational direction (411). For example, since the motor structure (361) to which the pinion gear (362) is connected is fixed with respect to the second housing part (220) and the rack gear (363) is fixed with respect to the first housing part (210), the second housing part (220) can be moved in the first direction (261) with respect to the first housing part (210) at least in part based on the movement of the rack gear (363) in the first direction (261). For example, since the second cover (321) within the second housing part (220) is coupled with at least a portion of the first area (230a) of the display (230), the display (230) can be moved in the first direction (261) at least in part based on the movement of the rack gear (363) in the first direction (261). For example, the display (230) can be moved along the rails (313a) of FIG. 3B. For example, as the support member (331) moves in the first direction (261) along the rails (313a), the display (230) supported by the support member (331) can be moved in the first direction (261). For example, the shape of at least a portion of the plurality of bars of the support member (331) of the display (230) can be changed when the first state (490) is changed to the second state (495).

[0098] For example, the second area (230b) of the display (230) may be moved according to the movement of the display (230). For example, the second area (230b) may be moved through the space between the first cover (311) and the frame (313) when the first state (490) is changed to the second state (495) according to the user input defined above. For example, the second area (230b) in the second state (495) may be visually exposed, unlike the second area (230b) rolled into the space in the first state (490).

[0099] For example, since the second cover (321) within the second housing part (220) is coupled with the PCB (324) connected to the other end of the FPCB (325) and fixes the rack gear (363), the shape of the FPCB (325) can be changed when the first state (490) is changed to the second state (495).

[0100] The motor structure (361) can be operated based at least in part on the defined user input received within the second state (495). For example, the pinion gear (362) can be rotated in the second rotational direction (412) based at least in part on the operation of the motor structure (361). For example, the rack gear (363) can be moved in the second direction (262) based at least in part on the rotation of the pinion gear (362) in the second rotational direction (412). For example, the second housing part (220) can be moved in the second direction (262) based at least in part on the movement of the rack gear (363) in the second direction (262). For example, the display (230) can be moved based at least in part on the movement of the rack gear (363) in the second direction (262). As the support member (331) moves in the second direction (262) along the rails (313a), the display (230) supported by the support member (331) can move in the second direction (262). For example, the display (230) can move along the rails (e.g., the rails (313a) of FIG. 3B). For example, the shape of at least a portion of the plurality of bars of the support member (331) of the display (230) can change when the second state (495) is changed to the first state (490). The support member (331) can move with respect to the first housing part (210). In the first state (490), the support member (331) housed inside the first housing part (210) can be positioned between the first cover (311) and the frame (313). The display (230) can be moved relative to the first housing part (210) according to the movement of the support member (331).

[0101] For example, the second area (230b) of the display (230) may be moved according to the movement of the display (230). For example, the second area (230b) may be moved through the space between the first cover (311) and the frame (313) when the second state (495) is changed to the first state (490) according to the user input defined above. For example, the second area (230b) in the first state (490) may be rolled into the space, unlike the second area (230b) that is visually exposed in the second state (495).

[0102] For example, since the second cover (321) within the second housing part (220) is coupled with the PCB (324) connected to the other end of the FPCB (325) and fixes the rack gear (363), the shape of the FPCB (325) can be changed when the second state (495) is changed to the first state (490).

[0103] FIGS. 2A to 4B illustrate an electronic device (200) in which the height of the display area is changed and the width of the display area is maintained when the first state (or the second state) is changed to the second state (or the first state) in the portrait mode, but this is for convenience of explanation. For example, the electronic device (200) may be implemented such that the height of the display area is maintained and the width of the display area is changed when the first state (or the second state) is changed to the second state (or the first state) in the portrait mode.

[0104] FIG. 5A is an exemplary plan view of a second housing part according to an embodiment. In FIG. 5A, the motor structure (361) is also illustrated for convenience of explanation. FIG. 5B is an exemplary side view of the second housing part according to an embodiment. FIG. 5C is an exemplary perspective view of the second housing part according to an embodiment. In FIG. 5C, the motor structure (361) and the rack gear (363) are illustrated together for convenience of explanation.

[0105] In FIGS. 5A, 5B, and 5C, the fifth direction (265) and the sixth direction (266) may be directions that are perpendicular to the first direction (261) and the second direction (262), which are the sliding direction of the second housing part (521), and perpendicular to the third direction (263) (e.g., the z-axis direction in FIG. 4B) that is the thickness direction of the second housing part (521). The sixth direction (266) may be opposite to the fifth direction (265).

[0106] Referring to FIGS. 5A, 5B, and 5C, an electronic device (200) according to one embodiment may include a second housing part (521) (e.g., the second housing part (220) of FIG. 3B or the second cover (321) of the second housing part (220).

[0107] In one embodiment, the second housing part (521) may include a support plate (510) on which the motor structure (361) is disposed and a side wall (530) that partially surrounds the support plate (510).

[0108] In one embodiment, the second housing part (521) may include a first side (530A) and a second side (530B) facing in an opposite direction to the first side (530A). The first side (530A) may be formed along a first direction (261). For example, the first side (530A) may extend along the first direction (261). The second side (530B) may be formed along the first direction (261). For example, the second side (530B) may extend along the first direction (261). The second side (530B) may be parallel to the first side (530A).

[0109] In one embodiment, the second housing part (521) (or support plate (510)) may include a plane (510A) that is substantially perpendicular to the first side (530A) and the second side (530B). Various components, such as a motor structure (361), a battery (e.g., a battery (319) of FIG. 3A), and a printed circuit board (e.g., a PCB (324) of FIG. 3A), may be arranged on the plane (510A). Although not shown, the second housing part (521) (or support plate (510)) may support a display of the electronic device (200) (e.g., a first region (230a) of the display (230) of FIG. 3A) and include a surface (or a second plane) opposite to the plane (510A).

[0110] In one embodiment, the first side wall (532) may form at least a portion of the first side wall (530A), and the second side wall (534) may form at least a portion of the second side wall (530B). In one embodiment, a first opening area (591) may be formed in the first side wall (530A), and a second opening area (592) may be formed in the second side wall (530B). The first opening area (591) and the second opening area (592) may each extend along a sliding direction of the second housing part (521) (e.g., the first direction (261)). In one embodiment, the first side wall (532) may not be formed in the first opening area (591), thereby allowing the second portion (514) of the support plate (510) to be opened. In this case, the first side (530A) may be formed by the second part (514) of the support plate (510) and the first side wall (532). Alternatively, unlike the illustration, the first side wall (532) may be formed in the first opening area (591), in which case the first side wall (532) may be formed at a lower height in the first opening area (591) than in other areas. In one embodiment, the second side wall (534) may not be formed in the second opening area (592), thereby allowing the second part (514) of the support plate (510) to be open. In this case, the second side (530B) may be formed by the second part (514) of the support plate (510) and the second side wall (534). Alternatively, unlike the city, the second side wall (534) may be formed in the second opening area (592), in which case the second side wall (534) may be formed at a lower height in the second opening area (592) than in other areas.

[0111] In one embodiment, the first side wall (532) and the second side wall (534) may be substantially parallel to the sliding direction of the second housing part (521). For example, the first side wall (532) and the second side wall (534) may be substantially parallel to the first direction (261) and the second direction (262).

[0112] In one embodiment, the support plate (510) and the side wall (530) of the second housing part (521) may be formed integrally, but is not limited thereto. For example, at least a portion of the side wall (530) may be joined to the support plate (510).

[0113] In one embodiment, the second housing part (521) may be formed of metal and / or plastic. For example, the support plate (510) and / or the side wall (530) may be formed of metal and / or plastic.

[0114] In one embodiment, the support plate (510) may include a first portion (512) surrounded by a side wall (530) and a second portion (514) extending from the first portion (512). For example, the first portion (512) may be surrounded by the first side wall (532), the second side wall (534), and the third side wall (536). The second portion (514) may not be surrounded by the side wall (530). The second portion (514) may extend from the first portion (512) toward the first housing part (210 of FIG. 4B).

[0115] In one embodiment, at least a portion of the side wall (530) may be formed with a thickness (e.g., a length along the third direction (263) or the fourth direction (264)) that is thicker than the support plate (510). For example, the first side wall (532) and the second side wall (534) may be thicker than the support plate (510).

[0116] In one embodiment, at least a portion of the side wall (530) may protrude from the support plate (510). For example, at least a portion of the side wall (530) may protrude from a plane (510A) of the support plate (510). For example, the first side wall (532) and the second side wall (534) may protrude in a fourth direction (264) from the plane (510A) of the support plate (510). The plane (510A) may include, for example, a surface of the support plate (510) that faces in an opposite direction (e.g., in the fourth direction (264)) to a display area (e.g., the first area (230a) and / or the second area (230b) of FIG. 2A) of a display (e.g., the display (230) of FIG. 2A) visible from the outside of the electronic device (200).

[0117] In one embodiment, the motor structure (361) may be disposed on a plane (510A) of the support plate (510). For example, the motor structure (361) may be disposed on a first portion (512) of the support plate (510). For example, the motor structure (361) may be coupled to the support plate (510). The coupling structure of the motor structure (361) and the support plate (510) is exemplified through the descriptions of FIGS. 10A to 10E.

[0118] In one embodiment, the support plate (510) may be formed with holes (515) penetrating the support plate (510) to accommodate the motor structure (361), but is not limited thereto. For example, at least some of the holes (515) may be formed as grooves formed on a plane (510A) of the support plate (510). In addition, although the holes (515) are illustrated as a plurality, this is not limiting, and the holes (515) may be formed as a single hole.

[0119] Vibrations transmitted from the motor structure (361) to the second housing part (521) may be amplified by the second housing part (521), thereby generating unpleasant noise. According to one embodiment, the second housing part (521) may include a wall structure that can reduce or prevent noise caused by the transmitted vibration by avoiding resonance due to the driving frequency of the motor structure (361).

[0120] For example, the second housing part (521) may include a first wall structure (560). For example, the first wall structure (560) may be formed on a relatively thin portion of the second housing part (521). The first wall structure (560) may extend between relatively thick portions of the second housing part (521). The first wall structure (560) may mitigate vibration transmitted from the motor structure (361) to the second housing part (521). Accordingly, noise generated by the relatively thin portion of the second housing part (521) that is relatively vulnerable to vibration may be reduced or prevented.

[0121] For example, the first wall structure (560) can be positioned on a support plate (510) that is thinner than the side wall (530). For example, the first wall structure (560) can be positioned on a first portion (512) of the support plate (510). For example, the first wall structure (560) can be formed (or positioned) on a plane (510A) of the second housing part (521) so as to be substantially perpendicular to the plane (510A). For example, the first wall structure (560) can protrude from the plane (510A) in a thickness direction of the support plate (510) (e.g., the fourth direction (264)). For example, the first wall structure (560) can extend between a first side wall (532) and a second side wall (534) that are thicker than the support plate (510). The fact that the first wall structure (560) extends between the first side wall (532) and the second side wall (534) does not mean that the first wall structure (560) is completely connected to the first side wall (532) and the second side wall (534). For example, the first wall structure (560) may extend from the first side wall (532) to the second side wall (534), thereby connecting the first side wall (532) and the second side wall (534). As another example, the first wall structure (560) may be interrupted in one or more sections that are formed at substantially the same height as the plane (510A) and / or formed at a lower height than adjacent sections.

[0122] In one embodiment, the first wall structure (560) can at least partially span the support plate (510). For example, the first wall structure (560) can extend in one or more directions (e.g., the sixth direction (266)) from the first sidewall (532) toward the second sidewall (534). For example, the first wall structure (560) can extend from the first sidewall (532) to the second sidewall (534). The first wall structure (560) can be positioned adjacent to the motor structure (361). For example, the first wall structure (560) can extend across the side of the motor structure (361). For example, the first wall structure (560) can extend along the motor structure (361). For example, the first wall structure (560) may include a section (e.g., the first wall (561) of FIG. 6a) that surrounds the motor structure (361). In one embodiment, the rack gear (363) may move along a sliding path of the second housing part (521) above the first wall structure (560) (e.g., in the fourth direction (264)). The first wall structure (560) may include a section (e.g., the fourth section (562-4) of FIG. 6b) that is formed to have a relatively low height so as not to interfere with the movement of the rack gear (363).

[0123] For example, the second housing part (521) may include a second wall structure (572, 574). The second wall structure (572, 574) may be formed on a portion of the support plate (510) where the side wall (530) is not formed. For example, the second wall structure (572, 574) may be formed on a portion of the second housing part (521) where the side wall (530) is not formed and where the thickness is relatively thin. For example, the second wall structure (572, 574) may be formed adjacent to the first opening area (591) and the second opening area (592). The portion where the second wall structure (572, 574) is positioned may be relatively vulnerable to vibration transmitted from the motor structure (361) because it is not only not covered by the side wall (530) but also has a relatively thin thickness. By forming the second wall structure (572, 574) on this part, noise caused by vibration transmitted from the motor structure (361) can be reduced or prevented.

[0124] For example, the second wall structure (572, 574) may include a first wall (572) and a second wall (574). The first wall (572) and the second wall (574) may be positioned on a second portion (514) of the support plate (510) that is positioned outside the side wall (530). For example, the first wall (572) and the second wall (574) may extend vertically from a plane (510A) of the second portion (514). In one embodiment, the position of the first wall (572) on the support plate (510) may be opposite to the position of the second wall (574) on the support plate (510). For example, the first wall (572) can be adjacent to the first opening area (591) of the support plate (510) (e.g., the second portion (514)), and the second wall (574) can be adjacent to the second opening area (592) of the support plate (510) (e.g., the second portion (514)). In one embodiment, the first wall (572) can extend in the first direction (261) along the first opening area (591) of the support plate (510). For example, the first wall (572) can be substantially parallel to the first side wall (532). In one embodiment, the second wall (574) can extend in the first direction (261) along the second opening area (492) of the support plate (510). For example, the second wall (574) can be substantially parallel to the second side wall (534). In one embodiment, the first wall (572) can be, but is not limited to, lower in height than the first side wall (532). In one embodiment, the second wall (574) can be, but is not limited to, lower in height than the second side wall (534). Although not shown, the second wall structure (572, 574) can further include another wall protruding from the second portion (514) to connect the first wall (572) and the second wall (574).

[0125] In one embodiment, the first wall (572) may include a section overlapping the first opening area (591). The first wall (572) may include a section overlapping the first opening area (591) along the first direction (261). In one embodiment, the second wall (574) may include a section overlapping the second opening area (592). The second wall (574) may include a section overlapping the second opening area (592) along the first direction (261).

[0126] For example, the second housing part (521) may include a third wall structure. The third wall structure may at least partially surround a motor structure (361) that transmits vibrations that may cause noise. The third wall structure may be positioned around the motor structure (361), which is a vibration source, to reduce or prevent noise caused by the transmitted vibrations being amplified in the second housing part (521).

[0127] For example, the third wall structure may include a portion of the first wall structure (560) surrounding the motor structure (361) (e.g., the first wall (561) and the first portion (562-1) of FIG. 6A) and a fourth wall (580) extending from the first wall structure (560). The fourth wall (580) may protrude from the first portion (512) of the support plate (510) to surround the motor structure (361). The portion of the first wall structure (560) and the fourth wall (580) may be formed to be equal to or higher than the height of the motor structure (361), but are not limited thereto.

[0128] In one embodiment, at least one (or at least a portion) of the first wall structure (560), the second wall structure (572, 574), and / or the fourth wall (580) may be formed integrally with the support plate (510), but is not limited thereto. For example, at least one (or at least a portion) of the first wall structure (560), the second wall structure (572, 574), and / or the fourth wall (580) may be formed as a separate piece from the support plate (510) and mechanically coupled or attached to the support plate (510).

[0129] In one embodiment, the first wall structure (560), the second wall structure (572, 574), or the fourth wall (580) may be referred to as a wall, a wall structure, a bulkhead structure, a reinforcing wall, a reinforcing structure, a projection, a projection surface, a side wall, a separation wall, a vibration damping structure, a column, a beam (wherein when referred to as a 'beam', the wall may be at least partially separated from the plane (510A)), a cross wall, or a crossbeam, but is not limited to the examples described above.

[0130] FIG. 6A is an exemplary perspective view illustrating a second housing part having a PCB and a camera module arranged thereon, according to one embodiment. FIG. 6B is an exemplary perspective view illustrating a second housing part according to one embodiment. FIG. 6C is an exemplary cross-sectional view of the second housing part according to one embodiment. FIG. 6C may be a cross-sectional view taken along line A-A' of FIG. 6A.

[0131] Referring to FIG. 6A, an electronic device (200) according to an embodiment may include a camera module (670) (e.g., the camera module (180) of FIG. 1) and a PCB (650) (e.g., the PCB (324) of FIG. 3A). The camera module (670) may include one or more cameras (e.g., the rear cameras (250-2) of FIG. 2B) arranged to face the rear direction (e.g., the fourth direction (264)) of the second housing part (521). The camera module (670) may be disposed on the second housing part (521). For example, the camera module (670) may be disposed on a plane (510A) of the support plate (510). The PCB (650) may be disposed on the second housing part (521). For example, the PCB (650) may be placed on a plane (510A) of the support plate (510).

[0132] In one embodiment, the first wall structure (560) may be positioned between the PCB (650) and the motor structure (361). For example, the PCB (650) may be positioned on one side of the first wall structure (560) (e.g., in the first direction (261)), and the motor structure (361) may be positioned on the other side of the first wall structure (560) (e.g., in the second direction (262)). The PCB (650) may be positioned between the camera module (670) and the first wall structure (560), but is not limited to the above-described example. For example, the first wall structure (560) may be positioned below the motor structure (361) (e.g., in the second direction (262)). For another example, the second housing part (521) may further include, in addition to the first wall structure (560), a wall or wall structure connecting the first side wall (532) and the second side wall (534) below the motor structure (361) (e.g., in the second direction (262)).

[0133] In one embodiment, the motor structure (361) may include a motor (or motor core) (610) including a rotor and a stator for generating torque from electrical energy, a reducer (620) for controlling torque by the motor (610), a motor bracket (630) for coupling the motor structure (361) to a second housing part (521), and an FPCB (640) for electrically connecting the motor structure (361) and a PCB (650). The motor bracket (630) may support the motor (610) and / or the reducer (620). The motor bracket (630) may be fixedly coupled to a support plate (510) of the second housing part (521).

[0134] Referring to FIGS. 6A and 6B , according to one embodiment, the first wall structure (560) may include a first wall (561), a second wall (562), and a third wall (563). The first wall (561) may be substantially perpendicular to the first side wall (532) or the second side wall (534), and / or substantially parallel to a rotational axis of the motor structure (361) (e.g., an axis of the first rotational direction (411) of FIG. 4A or an axis of the second rotational direction (412) of FIG. 4B ). The first wall (561) may be adjacent to the motor (610). For example, the first wall (561) may be positioned around the motor (610). The first wall (561) may be spaced apart from the motor (610). The rotation axis of the motor structure (361) may be substantially perpendicular to the sliding direction (e.g., the first direction (261)) of the second housing part (521).

[0135] In one embodiment, the second wall (562) can extend from the first wall (561). The second wall (562) can include at least one section (or wall) that is substantially perpendicular to the first sidewall (532) or the second sidewall (534) and / or substantially parallel to the rotational axis of the motor structure (361). For example, the at least one section of the second wall (562) can include at least one of a first section (562-1), a second section (562-2), a third section (562-3), and a fourth section (562-4). The first section (562-1), the second section (562-2), the third section (562-3), and the fourth section (562-4) of the second wall (562) can each be referred to as one wall, and the second wall (562) that includes them can be referred to as at least one second wall.

[0136] In one embodiment, a first wall (561) may be positioned between a second section (562-2) and a fourth section (562-4) of a second wall (562). For example, the second section (562-2) may extend from one side of the first wall (561), and the fourth section (562-4) may extend from the other side of the first wall (561).

[0137] In one embodiment, the first section (562-1) of the second wall (562) may be connected to the first wall (561) via the second section (562-2). The second section (562-2) may be formed at a lower height than the first section (562-1) and / or the first wall (561).

[0138] In one embodiment, the third section (562-3) of the second wall (562) may be connected to the first side wall (532). The third section (562-3) may be connected to the first wall (561) via a fourth section (562-4). The fourth section (562-4) may be formed at a lower height than the third section (562-3) and / or the first wall (561).

[0139] In one embodiment, the third wall (563) may include at least one section (or wall) extending from the first wall (561) and / or the second wall (562) in a different direction than the first wall (561) and the second wall (562). For example, the at least one section of the third wall (563) may include the first section (563-1) and / or the second section (563-2). The first section (563-1) and the second section (563-2) may each be referred to as one wall, and the third wall (563) including them may be referred to as at least one third wall.

[0140] In one embodiment, the first section (563-1) of the third wall (563) may extend from a portion of the second wall (562) where the third section (562-3) and the fourth section (562-4) of the second wall (562) meet in a direction different from the second wall (562-2) (e.g., in the second direction (262)). The second section (563-2) of the third wall (563) may extend from a portion where the first section (562-1) and the fourth wall (580) of the second wall (562) meet in a direction different from the second wall (562) (e.g., in the first direction (261)). The second section (562-2) of the third wall (563) may connect the first section (562-1) of the second wall (562) to the second side wall (534).

[0141] According to one embodiment, the first wall structure (560) may include one or more first sections that are substantially perpendicular to the first side wall (532) and the second side wall (534) and / or substantially parallel to a rotational axis of the motor structure (361) (e.g., the axis of the first rotational direction (411) of FIG. 4A or the axis of the second rotational direction (412) of FIG. 4B). For example, the one or more first sections may include, but are not limited to, a first wall (561) and a second wall (562).

[0142] In one embodiment, the first wall structure (560) may include one or more second sections formed to be relatively low in height to provide a path for the rack gear (363) to pass through. For example, the one or more second sections may include a fourth section (562-4) of the second wall (562). The fourth section (562-4) of the second wall (562) may be formed to be lower in height than the first wall (561) and / or the third section (562-3) connected to both sides of the fourth section (562-4). The rack gear (363) may be positioned, for example, above the fourth section (562-4) between the first wall (561) and the third section (562-3). The rack gear (363) can move, for example, along a path parallel to the sliding direction of the second housing part (521), between the third section (562-3) of the second wall (562) and the first wall (561), and over the fourth section (562-4). Alternatively or optionally, the fourth section (562-4) of the second wall (562) can be formed at substantially the same height on the plane (510A). That is, the second wall (562) may not include the fourth section (562-4).

[0143] In one embodiment, the first wall structure (560) may include one or more third sections formed to be relatively low in height to provide a path for the FPCB (640) of the motor structure (361) to pass through. For example, the one or more third sections may include a second section (562-2) of the second wall (562). The second section (562-2) of the second wall (562) may be formed to have a lower height than the third sections (562-3) connected to both sides of the second section (562-2) and / or the first wall (561). The FPCB (640) of the motor structure (361) may extend across the second section (562-2) of the second wall (562) to pass between the first section (562-1) of the second wall (562) and the first wall (561). For example, the FPCB (640) of the motor structure (361) may extend on or above the second section (562-2) of the second wall (562).

[0144] According to one embodiment, the first wall structure (560) may include one or more fourth sections substantially parallel to the rotational axis (e.g., the fifth direction (265)) of the motor structure (361) and extending along the motor structure (361). For example, the one or more fourth sections may include, but are not limited to, sections (562-1, 562-2) of the second wall (562) and the first wall (561).

[0145] According to one embodiment, the first wall structure (560) may include one or more fifth sections extending in a direction different from the rotational axis of the motor structure (361). For example, the one or more fifth sections may include, but are not limited to, a third wall (563). In one embodiment, each section of the first wall structure (560) may be referred to as one wall.

[0146] Referring to FIG. 6C, the electronic device (200) may include an FPCB (680) (e.g., the FPCB (325) of FIGS. 4A and 4B)) connected to a PCB (650). According to one embodiment, the PCB (650) may include a plurality of substrates that are stacked on each other. For example, the PCB (650) may include a first substrate (652), a second substrate (654) stacked on the first substrate (652), and a third substrate (656) stacked on the second substrate (654). In one embodiment, the PCB (650) may include a first connection substrate interposed between the first substrate (652) and the second substrate (654), and a second connection substrate interposed between the second substrate (654) and the third substrate. The first connection substrate and the second connection substrate may include an interposer. In one embodiment, the PCB (650) may include an upper surface (650A) and a lower surface (650B) opposite the upper surface (650A) and facing the plane (510A) of the support plate (510). The upper surface (650A) may be a surface of a substrate positioned at the uppermost layer among the plurality of substrates of the PCB (650), such as, for example, a third substrate (656). The lower surface (650B) may be a surface of a substrate positioned at the lowermost layer among the plurality of substrates of the PCB (650), such as, for example, a first substrate (652). A connector to which an FPCB (680) is coupled may be arranged on the upper surface (650A) of the PCB (650).

[0147] In one embodiment, the height of the upper surface (650A) may be formed higher than the height of the vertical end of the first wall structure (560). For example, the distance from the plane (510A) to the upper surface (650A), which is the height of the upper surface (650A), may be a first distance (a1). The distance from the plane (510A) to the vertical end of the first wall structure (560) may be a second distance (a2) that is smaller than the first distance (a1). Accordingly, the bonding of the PCB (650) and the FPCB (680) and the formation of the curved section of the FPCB (680) may not be interfered with by the first wall structure (560).

[0148] In one embodiment, the second housing part (521) may include a guide wall (660) for guiding the FPCB (680). The guide wall (660) may protrude from a plane (510A) of the support plate (510). The FPCB (680) may extend between the guide wall (660) and the first wall structure (560). The guide wall (660) may be formed to have a height substantially equal to a first distance (a1) which is a height of the upper surface (650A) of the PCB (650), but is not limited thereto.

[0149] FIG. 7A is an exemplary perspective view illustrating a second housing part having a rail structure coupled thereto, according to one embodiment. FIG. 7B is an exemplary cross-sectional view illustrating a rail structure and a second wall structure, according to one embodiment. FIG. 7C is an exemplary drawing illustrating a second wall structure of the second housing part, according to one embodiment.

[0150] Referring to FIGS. 7A and 7B, according to one embodiment, an electronic device (200) may include rail structures (740, 750) (e.g., rails (313a) of FIG. 3A) coupled to a second housing part (521).

[0151] For example, the first rail structure (740) may include a first fixed rail (742) and a first movable rail (744). The first fixed rail (742) may be fixedly coupled to an end of the first side wall (532) (e.g., an end in the second direction (262)). The first movable rail (744) may be movably coupled to the first fixed rail (742). For example, the first movable rail (744) may be slidably coupled to the first fixed rail (742) in conjunction with the sliding of the second housing part (521). For example, a first protrusion (743) extending along a sliding direction (e.g., the first direction (261)) of the second housing part (521) may be formed on the first fixed rail (742), and a first groove (747) for receiving the first protrusion (743) of the first fixed rail (742) may be formed on the first movable rail (744). The first movable rail (744) may move along a path guided by the first protrusion (743) of the first fixed rail (742) and the first groove (747) coupled thereto. In one embodiment, a first opening area (591) may be formed on the first side (530A) of the second housing part (521) so as not to interfere with the sliding of the first movable rail (744). For example, a first opening area (591) may be formed in the first side (530A) (or the first side wall (532)) so that the first side (530A) (or the first side wall (532)) does not overlap the first moving rail (744).

[0152] For example, the second rail structure (750) may include a second fixed rail (752) and a second movable rail (754). The second fixed rail (752) may be fixedly coupled to an end of the second side wall (534) (e.g., an end in the second direction (262)). The second movable rail (754) may be movably coupled to the second fixed rail (752). For example, the second movable rail (754) may be slidably coupled to the second fixed rail (752) in conjunction with the sliding of the second housing part (521). For example, although not shown, the second fixed rail (752) may be formed with a protrusion (e.g., a first protrusion (743)) extending along the sliding direction (e.g., the first direction (261)) of the second housing part (521), and the second movable rail (754) may be formed with a groove (e.g., a first groove (747)) that receives the protrusion of the second fixed rail (752). The second movable rail (754) may move along a path guided by the protrusion of the second fixed rail (752) and the groove coupled thereto. In one embodiment, a second opening area (592) may be formed on the second side (530B) of the second housing part (521) so as not to interfere with the sliding of the second movable rail (754). For example, a second opening area (592) may be formed in the second side (530B) (or the second side wall (534)) so that the second side (530B) (or the second side wall (534)) does not overlap the second moving rail (754).

[0153] Although not shown, the first moving rail (744) and the second moving rail (754) may be fixedly connected to the first housing part (e.g., the first housing part (210) of FIG. 4B). The first rail structure (740) and the second rail structure (750) may enable stable sliding of the second housing part (521) relative to the first housing part (210).

[0154] In one embodiment, the first fixed rail (742) or the second fixed rail (752) may be referred to as a slide fixed support. The first movable rail (744) or the second movable rail (754) may be referred to as a slide fixed support. In addition, since the first fixed rail (742) and the first movable rail (744) are capable of relative movement, the first fixed rail (742) may be referred to as the first movable rail (or slide fixed support), and the first movable rail (744) may be referred to as the first fixed rail (or slide fixed support). In addition, since the second fixed rail (752) and the second movable rail (754) are capable of relative movement, the second fixed rail (752) may be referred to as the first movable rail (or slide fixed support), and the second movable rail (754) may be referred to as the second fixed rail (or slide fixed support). The first movable rail (744) and the second movable rail (754) may be referred to as a pair of movable rails (or fixed rails) or a pair of sliding movable supports (or slide fixed supports). The first fixed rail (742) and the second fixed rail (752) may be referred to as a pair of fixed rails (or moving rails) or a pair of sliding fixed supports (or slide moving supports).

[0155] Referring to FIG. 7B, in one embodiment, the first movable rail (744) may be movably coupled to the first wall (572). For example, the first movable rail (744) may be slidably coupled to the first wall (572) in conjunction with the sliding of the second housing part (521). For example, the first wall (572) may guide the movement of the first movable rail (744). For example, the first wall (572) may be accommodated within a second groove (745) of the first movable rail (744) extending along the sliding direction of the second housing part (521) (e.g., the first direction (261)). Additionally, a portion of the first movable rail (744) may be accommodated within a groove (573) of the first wall (572) extending along the sliding direction of the second housing part (521). The second groove (745) of the first movable rail (744) in which the first wall (572) is accommodated may be located on the opposite side of the first groove (747) in which the first protrusion (743) of the first fixed rail (742) is accommodated. Since the first fixed rail (742) and the first wall (572) guide the movement of the first movable rail (744) on both sides of the first movable rail (744), the second housing part (521) can slide more stably.

[0156] In one embodiment, the second movable rail (754) can be movably coupled to the second wall (574). For example, the second movable rail (754) can be slidably coupled to the second wall (574) in conjunction with the sliding of the second housing part (521). For example, the second wall (574) can guide the movement of the second movable rail (754). For example, the second wall (574) can be accommodated within another groove (e.g., the second groove (745)) of the second movable rail (754) that extends along the sliding direction (e.g., the first direction (261)) of the second housing part (521). A portion of the second movable rail (754) can be accommodated within another groove (e.g., the groove (573)) of the second wall (574) that extends along the sliding direction of the second housing part (521). The other groove of the second movable rail (754) in which the second wall (574) is accommodated may be located on the opposite side of the groove in which the protrusion of the second fixed rail (752) is accommodated. Since the second fixed rail (752) and the second wall (574) guide the movement of the second movable rail (754) on both sides of the second movable rail (754), the second housing part (521) can slide more stably.

[0157] Referring to FIG. 7C, according to one embodiment, the first wall (572) may extend along the sliding direction of the second housing part (521) (e.g., the first direction (261)). The first wall (572) may be located at an edge of the support plate (510). The first wall (572) may include a section that overlaps the first side wall (532). In various embodiments of the present disclosure, “overlapping” only means that at least a portion of a component is located within the boundary of another component when projected from a particular point of view, and is not construed as physically contacting or spaced apart from each other unless specifically stated.

[0158] For example, the first wall (572) may include a first section (771) protruding from a second portion (514) of the support plate (510) and a second section (772) extending from the first section (771) and protruding from the first portion (512) of the support plate (510). The first section (771) may overlap the first opening area (591). The second section (772) may overlap the first side wall (532), and the first section (771) may not overlap the first side wall (532). For example, the second section (772) of the first wall (572) may overlap the first side wall (532) when viewed in the fifth direction (265). Referring also to FIG. 7A, in one embodiment, a first rail structure (740) may be partially positioned between the first side wall (532) and the second section (772) of the first wall (572). For example, a first fixed rail (742) may be disposed on the inner surface of the first side wall (532) facing the first wall (572). For example, the first fixed rail (742) disposed on the inner surface of the first side wall (532) may be coupled to the first side wall (532) via a screw penetrating the first side wall (532). In one embodiment, the first wall (572) may extend beyond the second portion (514) of the support plate (510) to the first portion (512) such that it overlaps the first side wall (532), thereby sufficiently securing an increase in stiffness required to control vibration transmission characteristics. In addition, by extending beyond the second part (514) of the support plate (510) to the first part (512) so that the first wall (572) overlaps the first side wall (532), the length of the path along which the first rail structure (740) is guided by the first wall (572) can be improved, and the stability of the sliding of the second housing part (521) guided by the first rail structure (740) can be improved.

[0159] According to one embodiment, the second wall (574) may extend along a sliding direction of the second housing part (521) (e.g., the first direction (261)). The second wall (574) may be located at an edge of the support plate (510). The second wall (574) may include a section overlapping the second side wall (534). For example, the second wall (574) may include a first section (773) protruding from the second portion (514) of the support plate (510) and a second section (774) extending from the first section (773) and protruding from the first portion (512) of the support plate (510). The first section (773) may overlap the second opening area (592). The second section (774) may overlap the second side wall (534), and the first section (773) may not overlap the second side wall (534). For example, the second section (774) of the second wall (574) may overlap the second side wall (534) when viewed in the fourth direction (264). Referring also to FIG. 7A, in one embodiment, a second rail structure (750) may be partially positioned between the second side wall (534) and the second section (774) of the second wall (574). For example, a second fixed rail (752) may be disposed on the inner surface of the second side wall (534) facing the second wall (574). For example, the second fixed rail (752) disposed on the inner surface of the second side wall (534) may be coupled to the second side wall (534) via a screw penetrating the second side wall (534). In one embodiment, the second wall (574) may extend beyond the second portion (514) of the support plate (510) to the first portion (512) so as to overlap the second side wall (534), thereby securing an increase in stiffness required to control vibration transmission characteristics.In addition, by extending beyond the second part (514) of the support plate (510) to the first part (512) so that the second wall (574) overlaps the second side wall (534), the length of the path along which the second rail structure (750) is guided by the second wall (574) can be improved, and the stability of the sliding of the second housing part (521) guided by the second rail structure (750) can be improved.

[0160] In one embodiment, the first rail structure (740) and / or the second rail structure (750) may be referred to as a linear motion guide for guiding sliding movement of the second housing part (521) relative to the first housing part (e.g., the first housing part (210) of FIG. 4B).

[0161] In one embodiment, the first fixed rail (742) and the first movable rail (744) of the first rail structure (740) may be referred to as a first slide fixed support and a first slide movable support; a first guide rail and a first guide block; a first guide body and a first guide head; a first guide fixed portion and a first guide movable portion; or a first guide portion and a second guide portion.

[0162] In one embodiment, the second fixed rail (752) and the second movable rail (754) of the second rail structure (750) may be referred to as a second slide fixed support and a second slide movable support; a second guide rail and a second guide block; a second guide body and a second guide head; a second guide fixed portion and a second guide movable portion; or a third guide portion and a fourth guide portion.

[0163] FIG. 8 is a drawing showing vibration characteristics of a second housing part. Example (810) of FIG. 8 shows vibration characteristics of a second housing part according to a comparative embodiment, and example (820) of FIG. 8 shows vibration characteristics of a second housing part (521) according to an embodiment. The second housing part according to the comparative embodiment of example (810) may not include wall structures for preventing vibration of a motor structure from being amplified into noise, such as a first wall structure (560), a first wall (572), a second wall (574), and a fourth wall (580), and the second housing part (521) according to an embodiment of example (820) may include a first wall structure (560), a first wall (572), a second wall (574), and a fourth wall (580).

[0164] Referring to Fig. 8, in the case of example (820), the vibration displacement can be reduced overall compared to example (810). Referring to Fig. 5a, since the rigidity is improved through the first wall structure (560) around the motor structure (361), the vibration displacement of the support plate (510) on which the motor structure (361) is disposed can be reduced, and the vibration transmitted from the motor structure (361) to the lower portion (e.g., the second portion (514)) of the support plate (510) can be reduced. In addition, due to the first wall (572) and the second wall (574), the shaking of the second portion (514) of the support plate (510) can be reduced. Accordingly, noise amplified due to the vibration can be reduced.

[0165] FIG. 9 is a graph showing vibration characteristics according to frequency of a second housing part according to an embodiment. Graph (910) of FIG. 9 shows vibration characteristics according to frequency of a second housing part according to a comparative example, graph (920) shows vibration characteristics of a second housing part (521) including a fourth wall (580), and graph (930) shows vibration characteristics of a second housing part (521) including a first wall structure (560), a first wall (572), and a second wall (574) in addition to the fourth wall (580).

[0166] Referring to FIG. 9, the displacement of the vibration in the graph (920) may be reduced compared to the graph (910) and may be shifted to the right. The displacement of the vibration in the graph (930) may be reduced compared to the graph (920) and may be shifted to the right. In addition to reducing the displacement of the vibration, the degree of noise amplification may be reduced by shifting the vibration characteristics in a specific direction. For example, the motor structure (361) may have an operating frequency of about 1,600 Hz to about 2,000 Hz. The peaks of the graphs (910, 920) overlap within the operating frequency range of the motor structure (361), so that the degree of noise amplification due to the vibration transmitted by the motor structure (361) may be increased. In contrast, the peak of the graph (930) is located outside the operating frequency range of the motor structure (361), so that resonance of the second housing part (521) caused by vibration transmitted from the motor structure (361) can be reduced or prevented. Accordingly, noise caused by vibration transmitted from the motor structure (361) being amplified by the second housing part (521) can be reduced or prevented. This may be because the rigidity of the second housing part (521) is improved by the first wall structure (560), the first wall (572), the second wall (574), and the fourth wall (580), thereby increasing the natural frequency of the second housing part (521).

[0167] Alternatively to the wall structures described above, the material of the second housing part (521) may be changed or its mass may be increased to reduce vibration displacement and / or shift vibration characteristics. However, changing the material may be unsuitable because it changes other characteristics of the electronic device (200) (e.g., antenna characteristics), and increasing the mass may be unsuitable because it reduces the portability of the electronic device (200).

[0168] FIG. 10A is an exemplary plan view of a second housing part according to one embodiment. FIG. 10B is an exemplary drawing showing a motor structure according to one embodiment. FIG. 10C is an exemplary cross-sectional view taken along line B-B' of FIG. 10A. FIG. 10D is an exemplary cross-sectional view taken along line C-C' of FIG. 10A. FIG. 10E is an exemplary cross-sectional view taken along line D-D' of FIG. 10A.

[0169] In Fig. 10a, the rotation axis (A1) of the motor structure (361) and the movement axis (A2) of the rack gear (363) are illustrated together. The rotation axis (A1) of the motor structure (361) may be substantially perpendicular to the sliding direction (e.g., the first direction (261)) of the second housing part (521), and the movement axis (A2) of the rack gear (363) may be substantially parallel to the sliding direction (e.g., the first direction (261)) of the second housing part (521).

[0170] Referring to FIGS. 10A and 10B , in one embodiment, a plurality of fastening holes may be formed in the second housing part (521) for fixedly connecting the motor structure (361). For example, a first fastening hole (1051), a second fastening hole (1052), and a third fastening hole (1053) may be formed in the first part (512) of the support plate (510). In one embodiment, each of the first fastening hole (1051), the second fastening hole (1052), and the third fastening hole (1053) may at least partially penetrate the support plate (510).

[0171] For example, the first fastening hole (1051) and the second fastening hole (1052) can be arranged based on the rotation axis (A1) of the motor structure (361) (e.g., a direction parallel to the fifth direction (265)). For example, the rotation axis (A1) of the motor structure (361) can pass between the first fastening hole (1051) and the second fastening hole (1052). For example, the first fastening hole (1051) can be located in one direction (e.g., the second direction (262)) based on the rotation axis (A1) of the motor structure (361), and the second fastening hole (1052) can be located in an opposite direction (e.g., the first direction (261)) of the one direction based on the rotation axis (A1) of the motor structure (361). In one embodiment, the first fastening hole (1051) may overlap with the rack gear (363) or the movement axis (A2) of the rack gear (363). For example, when the second housing part (521) is viewed from above (e.g., when viewed in the third direction (263)), the first fastening hole (1051) may overlap with the rack gear (363) or the movement axis (A2) of the rack gear (363).

[0172] For example, the first fastening hole (1051) and the third fastening hole (1053) may be arranged based on the rotation axis (A1) of the motor structure (361). For example, the rotation axis (A1) of the motor structure (361) may pass between the first fastening hole (1051) and the third fastening hole (1053). For example, the first fastening hole (1051) may be located in one direction (e.g., the second direction (262)) based on the rotation axis (A1) of the motor structure (361), and the third fastening hole (1053) may be located in the opposite direction (e.g., the first direction (261)) of the one direction based on the rotation axis (A1) of the motor structure (361).

[0173] For example, the second fastening hole (1052) and the third fastening hole (1053) may be arranged based on the movement axis (A2) of the rack gear (363). For example, the movement axis (A2) of the rack gear (363) may pass between the second fastening hole (1052) and the third fastening hole (1053). For example, the second fastening hole (1052) may be located in one direction (e.g., the fifth direction (265)) based on the movement axis (A2) of the rack gear (363), and the third fastening hole (1053) may be located in the opposite direction (e.g., the sixth direction (266)) of the one direction based on the movement axis (A2) of the rack gear (363).

[0174] Referring to FIG. 10b, in one embodiment, a plurality of corresponding holes may be formed in the motor bracket (630), each corresponding to the plurality of fastening holes formed in the second housing part (521). For example, a first corresponding hole (1031), a second corresponding hole (1032), and a third corresponding hole (1033) may be formed in the motor bracket (630), which are aligned with the first fastening hole (1051), the second fastening hole (1052), and the third fastening hole (1053) of the support plate (510), respectively. The first corresponding hole (1031), the second corresponding hole (1032), and the third corresponding hole (1033) may pass through the motor bracket (630).

[0175] In one embodiment, the motor structure (361) may be positioned on one side of the FPCB (640). On the other side (640B) of the FPCB (640) opposite to the one side, a plurality of connecting portions (1042) may be protrudingly formed to electrically connect the coils inside the motor (610). The plurality of connecting portions (1042) may include conductive terminals or conductive contacts that are electrically connected to the battery and / or power management module (e.g., the power management module (188) of FIG. 1) of the electronic device (200) to supply power to the motor (610) or the coils of the motor (610). Although not illustrated in FIG. 10B, as described below with reference to FIG. 13, the plurality of connecting portions (1042) may be at least partially positioned within the holes (515) of the support plate (510).

[0176] Referring to FIGS. 10c, 10d, and 10e, in one embodiment, the second housing part (521) may include a cover (1022) (e.g., the second plate (322) of FIG. 3b) disposed on the support plate (510). In one embodiment, the motor bracket (630) may be coupled to the support plate (510) via a plurality of screws that pass through the motor bracket (630) or through the motor bracket (630) and the cover (1022) and are fastened to the plurality of fastening holes of the support plate (510).

[0177] For example, referring to FIG. 10c, the cover (1022), the motor bracket (630), and the support plate (510) can be coupled to each other through a screw (1082) that passes through a second corresponding hole (1032) of the cover (1022), the motor bracket (630), and is fastened to a second fastening hole (1052) of the support plate (510).

[0178] For example, referring to FIG. 10d, according to one embodiment, the cover (1022), the motor bracket (630), and the support plate (510) can be coupled to each other through a screw (1083) that passes through the third corresponding hole (1033) of the cover (1022), the motor bracket (630), and is fastened to the third fastening hole (1053) of the support plate (510).

[0179] For example, referring to FIG. 10e, according to one embodiment, the motor bracket (630) and the support plate (510) can be coupled to each other through a screw (1081) that passes through the first corresponding hole (1031) of the motor bracket (630) and is fastened to the first fastening hole (1051) of the support plate (510).

[0180] Referring again to FIG. 10d, in one embodiment, the second housing part (521) may include a lubricating member (1090) disposed between the rack gear (363) and the cover (1022). For example, the lubricating member (1090) may be positioned in a gap between the rack gear (363) and the cover (1022). For example, the lubricating member (1090) may be disposed between the back surface of the cover (1022) facing the rack gear (363) and the teeth root of the rack gear (363). For example, the lubricating member (1090) may be attached to the back surface of the cover (1022) and / or the teeth root of the rack gear (363). The lubricating member (1090) can reduce or prevent flow in the thickness direction (e.g., the third direction (263) or the fourth direction (264)) of the rack gear (363) when the rack gear (363) moves. In addition, the lubricating member (1090) can reduce or prevent vibration and / or noise caused by friction between the rack gear (363) and the cover (1022) when the rack gear (363) moves. The lubricating member (1090) can include, for example, Teflon tape, but is not limited thereto.

[0181] In one embodiment, when force is transmitted from a pinion gear (362) connected to a reducer (620) of the motor structure (361) to the rack gear (363) through the first fastening hole (1051), the second fastening hole (1052), and the third fastening hole (1053) arranged around the rotational axis (A1) of the motor structure (361) and the movement axis (A2) of the rack gear (363), the vibration amplitude of the rack gear (363) can be reduced. For example, through the first fastening hole (1051) and the second fastening hole (1052) positioned with the rotational axis (A1) of the motor structure (361) interposed therebetween, the motor structure (361) and the rack gear (363) to which force of the motor structure (361) is transmitted can be reduced or prevented from vibrating around the rotational axis (A1). For example, through the first fastening hole (1051) and the third fastening hole (1053) positioned with the rotation axis (A1) of the motor structure (361) interposed therebetween, the motor structure (361) and the rack gear (363) to which the force of the motor structure (361) is transmitted can be reduced or prevented from vibrating about the rotation axis (A1). For example, through the second fastening hole (1052) and the third fastening hole (1053) positioned with the movement axis (A2) of the rack gear (363) interposed therebetween, the motor structure (361) and the rack gear (363) to which the force of the motor structure (361) is transmitted can be reduced or prevented from vibrating about the movement axis (A2). In this way, due to the reduction in the vibration amplitude of the motor structure (361) and the rack gear (363), not only can the noise generated by the vibration being amplified by the second housing part (521) be reduced, but the power transmission efficiency of the motor structure (361) for sliding the second housing part (521) can also be improved. The effect of reducing the vibration displacement described above is exemplified in the descriptions of FIGS. 11 and 12.

[0182] Figures 11 and 12 are diagrams showing the vibration displacement of the second housing part over time. In the description of Figures 11 and 12, the drawings described above may be referred to. In Figures 11 and 12, the motor structure (361) can operate in a constant velocity section from about 0.5 seconds onwards.

[0183] Fig. 11 is a diagram showing the vibration displacement along the X-axis (e.g., the rotation axis (A1) of Fig. 10a) of the second housing part (521) when the motor structure (361) is in operation. The graph (1120) of Fig. 11 shows the vibration characteristics of the second housing part (521) having a fastening structure through screws (1081, 1082, and 1083) between the motor structure (361) and the second housing part (521) as exemplified in the descriptions of Figs. 10a to 10e according to one embodiment. The graph (1110) shows the vibration characteristics of the second housing part to which the motor structure is fixedly coupled through screws having a different arrangement from the screws (1081, 1082, and 1083) in a comparative example.

[0184] Referring to FIG. 11, in a constant velocity section of the motor structure (361), the vibration displacement along the X-axis of the graph (1120) may be reduced compared to the vibration displacement along the X-axis of the graph (1100). For example, the vibration displacement along the X-axis of the graph (1120) may be reduced by about 22% compared to the vibration displacement along the X-axis of the graph (1100).

[0185] Fig. 12 is a diagram showing the vibration displacement along the Y-axis (e.g., the movement axis (A2) of Fig. 10a) of the second housing part (521) when the motor structure (361) is in operation. The graph (1220) of Fig. 12 shows the vibration characteristics of the second housing part (521) having a fastening structure through screws (1081, 1082, and 1083) between the motor structure (361) and the second housing part (521) as exemplified in the descriptions of Figs. 10a to 10e according to one embodiment. The graph (1210) shows the vibration characteristics of the second housing part to which the motor structure is fixedly coupled through screws having a different arrangement from the screws (1081, 1082, and 1083) in a comparative example.

[0186] Referring to FIG. 12, in the constant velocity section of the motor structure (361), the vibration displacement along the Y axis of the graph (1120) may be reduced compared to the vibration displacement along the Y axis of the graph (1100). For example, the vibration displacement along the Y axis of the graph (1120) may be reduced by about 7% compared to the vibration displacement along the Y axis of the graph (1100).

[0187] FIG. 13 is an exemplary drawing showing a motor structure disposed on a second housing part according to one embodiment.

[0188] Referring to FIG. 13, in one embodiment, the motor structure (361) may include a motor (or motor core) (1010) (e.g., motor (610) of FIG. 6a), a reducer (1020) coupled to the motor (610) (e.g., reducer (620) of FIG. 6a), a motor bracket (1030) supporting the motor (1010) and the reducer (1020) (e.g., motor bracket (630) of FIG. 6a), and an FPCB (1040) (e.g., FPCB (640) of FIG. 6a) electrically connecting the motor structure (361) and a PCB (e.g., PCB (650) of FIG. 6c).

[0189] In one embodiment, the motor structure (361) may be disposed on the support plate (510) of the second housing part (521). For example, the motor structure (361) may be disposed on the support plate (510) such that the FPCB (1040) faces the support plate (510). The plurality of connecting portions (1042) protruding from the FPCB (1040) may be at least partially accommodated within the holes (515) of the support plate (510). In this way, by disposing the FPCB (1040) of the motor structure (361) on the support plate (510), the mounting space of the second housing part (521) may be saved.

[0190] In one embodiment, an electronic device (e.g., an electronic device (200) of FIG. 2A) comprises a first housing part (e.g., a first housing part (210) of FIG. 3A), a second housing part (e.g., a second housing part (521) of FIG. 5A) slidably coupled to the first housing part in a first direction (e.g., a first direction (261) of FIG. 5A), and including a first side (e.g., a first side (530A) of FIG. 5A) and a second side (e.g., a second side (530B) of FIG. 5A), formed along the first direction, and disposed on a first plane (e.g., a plane (510A) of FIG. 5A) between the first side and the second side in the second housing part and substantially perpendicular to at least one of the first side and the second side, and having a rotational axis in a second direction (e.g., a fifth direction (265) of FIG. 5A) perpendicular to the first direction. It may include a motor (e.g., motor (610) of FIG. 6a), a first wall (e.g., first wall (561) of FIG. 6b) formed around the motor substantially parallel to the second direction and arranged substantially perpendicular to the first plane, and at least one second wall (e.g., second wall (562) of FIG. 6b) extending from the first wall in the second direction. Accordingly, noise that may be generated by vibration of the motor being transmitted to the second housing part may be reduced.

[0191] In one embodiment, the electronic device may include at least one third wall (e.g., the third wall (563) of FIG. 6B) extending from the first wall or the at least one second wall in a direction different from the second direction.

[0192] In one embodiment, the first wall, the at least one second wall, and the at least one third wall are connected to each other and can cross the first plane of the second housing part.

[0193] In one embodiment, the motor may provide a driving force to rotate the second housing part about the rotational axis to move the first housing part.

[0194] In one embodiment, the electronic device may include a wall structure (e.g., the first wall structure (560) of FIG. 5A) extending between the first side and the second side to mitigate vibration of the second housing part due to driving of the motor. The wall structure may include the first wall and at least one second wall.

[0195] In one embodiment, the electronic device may include a fourth wall extending from the first wall (e.g., the fourth wall (580) of FIG. 6A) to surround at least a portion of the motor together with the first wall.

[0196] In one embodiment, the electronic device may include a printed circuit board (e.g., printed circuit board (650) of FIG. 6a), a fifth wall spaced apart from the first wall (e.g., first section (562-1) of FIG. 6b), and a flexible printed circuit board (e.g., FPCB (640) of FIG. 6a) electrically connecting the motor to the printed circuit board and positioned between the first wall and the fifth wall.

[0197] In one embodiment, the electronic device may include a sixth wall (e.g., the second section (562-2) of FIG. 6B) extending from the first wall to the fifth wall.
