[0032] FIG. 1 is a block diagram of an electronic device within a network environment according to various embodiments.

[0033] Referring to FIG. 1, in a network environment (100), an electronic device (101) may communicate with an electronic device (102) via a first network (198) (e.g., a short-range wireless communication network), or may communicate with at least one of an electronic device (104) or a server (108) via a second network (199) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (101) may communicate with the electronic device (104) via the server (108).

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

[0035] The auxiliary processor (123) may control at least a portion 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)).

[0038] 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).

[0039] 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. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0040] 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.

[0041] 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).

[0042] 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.

[0043] 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.

[0044] 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).

[0045] The 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.

[0046] 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.

[0047] 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).

[0048] 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.

[0049] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0050] 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) can 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.

[0051] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In 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). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected antenna. In 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).

[0052] According to various embodiments, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0053] 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)).

[0054] 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 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.

[0055] FIG. 2a is a plan view of an exemplary electronic device (101) in a first state.

[0056] Referring to FIG. 2A, the electronic device (101) may include a first housing (210), a housing (200) including a second housing (220) movable relative to the first housing (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), and a display (230) (e.g., the display).

[0057] For example, the electronic device (101) may be in the first state. For example, within the first state, the second housing (220) may be movable relative to the first housing (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 (220) may not be movable relative to the first housing (210) in a second direction (262) opposite to the first direction (261).

[0058] 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 area (230a). For example, although not shown in FIG. 2A, within the first state, the area (230a), which is the display area, and another area of ​​the display (230) (e.g., area (230b) of FIG. 2C) may be located within the first housing (210). For example, within the first state, the area may be covered by the first housing (210). For example, within the first state, the area may be rolled into the first housing (210). For example, within the first state, the area (230a) may include a flat portion, unlike the area including a curved portion (or a bent portion). However, the present invention is not limited thereto. For example, the region (230a) may include a curved portion extending from the planar portion and positioned within the edge portion, within the first state.

[0059] For example, the first state may be referred to as a slide-in state or a closed state in that at least a portion of the second housing (220) is positioned within the first housing (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.

[0060] For example, the first housing (210) may include a first image sensor (250-1) within the camera module (180) that is visually exposed through a portion of the area (230a) and faces in a third direction (263) parallel to the z-axis. For example, the camera module (180) may also be arranged to perform its function within the internal space of the electronic device without being visually exposed through a portion of the area (230a). For example, although not illustrated in FIG. 2A, the second housing (220) may include one or more second image sensors within the camera module (180) that are exposed through a portion of the second housing (220) and faces in a fourth direction (264) parallel to the z-axis and opposite to the third direction (263). For example, the one or more second image sensors may be exemplified through the description of FIG. 2B.

[0061] FIG. 2b is a bottom view of an exemplary electronic device in a first state.

[0062] Referring to FIG. 2B, within the first state, one or more second image sensors (250-2) disposed within the second housing (220) may be positioned within a structure disposed within the first housing (210) for the one or more second image sensors (250-2). For example, light from outside the electronic device (101) may be received by the one or more second image sensors (250-2) through the structure within the first state. For example, since the one or more second image sensors (250-2) are positioned within the structure within the first state, the one or more second image sensors (250-2) may be exposed through the structure within the first state. 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) in a plate (212) of a first housing (210) that surrounds at least a portion of a second housing (220). However, the present invention is not limited thereto. For example, in the first state, one or more second image sensors (250-2) included in the second housing (220) may be covered by the plate (212) of the first housing (210).

[0063] Referring again to FIG. 2a, the first state can be changed to the second state.

[0064] For example, the first state (or the second state) may be changed to the second state (or the first state) through one or more intermediate states between the first state and the second state.

[0065] 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 to a physical button exposed through a portion of the first housing (210) or a portion of the second housing (220). For example, the first state (or the second state) may be changed to the second state (or the first state) in response to a touch input to an executable object displayed within the display area. For example, the first state (or the second state) may be changed to the second state (or the first state) in response to a touch input having a contact point on the display area and having a pressing strength greater than or equal to a reference strength. For example, the first state (or the second state) may be changed to the second state (or the first state) in response to a voice input received through a microphone of the electronic device (101). For example, the first state (or the second state) may be changed to the second state (or the first state) in response to an external force applied to the first housing (210) and / or the second housing (220) to move the second housing (220) with respect to the first housing (210). 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 identified from an external electronic device (e.g., earbuds or a smart watch) connected to the electronic device (101). However, the present invention is not limited thereto.

[0066] The second state can be illustrated through the descriptions of FIGS. 2c and 2d.

[0067] Figure 2c is a plan view of an exemplary electronic device within a second state.

[0068] Referring to FIG. 2C, the electronic device (101) may be in the second state. For example, in the second state, the second housing (220) may be movable relative to the first housing (210) in a second direction (262) among the first direction (261) and the second direction (262). For example, in the second state, the second housing (220) may not be movable relative to the first housing (210) in the first direction (261) opposite to the second direction (262).

[0069] 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 an area (230a) and an area (230b). For example, an area (230b) located within the first housing (210) within the first state may be exposed outside the housing (210) within the second state. For example, within the second state, the area (230a) may include a planar portion. However, the present invention is not limited thereto. For example, the area (230a) may also include a curved portion extending from the planar portion and positioned within the edge portion. For example, within the second state, the area (230b) may include a planar portion among the planar portion and the curved portion, unlike the area (230a) within the first state. However, the present invention is not limited thereto. For example, the region (230b) may include a curved portion extending from the planar portion of the region (230b) and positioned within the edge portion.

[0070] For example, the display (230) may include a first display area (231) disposed on a second housing (220), and a second display area (232) extending from the first display area (231) and at least partially recessed within the first housing (210) or visually exposed to the outside of the electronic device (101) as the second housing (220) moves relative to the first housing (210). For example, the first display area (231) may be a portion of the display (230) that is visually exposed to the outside of the electronic device (101). The first display area (231) may be a portion that is not deformed as the second housing (220) moves relative to the first housing (210). For example, the second display area (232) may be a portion of the display (230) that is deformed as the second housing (220) moves relative to the first housing (210). The above display (230) may be referred to as a flexible display in that it includes a deformable second display area (232), but is not limited thereto.

[0071] For example, the second state may be referred to as a slide-out state or an open state in that at least a portion of the second housing (220) is positioned outside the first housing (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 first image sensor (250-1) facing the third direction (263) may move together with the area (230a) according to the movement of the second housing (220) in the second direction (262) when the state of the electronic device (101) changes from the first state to the second state. For example, although not shown in FIG. 2c, one or more second image sensors (250-2) facing the fourth direction (264) may move according to the movement of the second housing (220) in the second direction (262) when the state of the electronic device (101) changes from the first state to the second state. For example, the relative positional relationship between one or more second image sensors (250-2) and the structure within the first housing (210) illustrated through the description of FIG. 2b may change according to the movement of one or more second image sensors (250-2). For example, the change in the above relative position relationship can be illustrated through Fig. 2d.

[0073] FIG. 2d is a bottom view of an exemplary electronic device (101) in a second state.

[0074] Referring to FIG. 2d, within the second state, one or more second image sensors (250-2) may be positioned outside the structure (e.g., an opening or a notch) within the first housing (210) as illustrated in the description of FIG. 2b. For example, within the second state, one or more second image sensors (250-2) may be positioned outside the opening (212a) within the plate (212). For example, one or more second image sensors (250-2) may be exposed through the opening (212a) within the first state. One or more second image sensors (250-2) may be exposed by being positioned outside the opening (212a) within the second state. For example, since one or more second image sensors (250-2) are positioned outside the structure within the second state, the relative positional relationship between one or more second image sensors (250-2) within the second state and the structure within the first housing (210) illustrated through the description of FIG. 2B may be different from the relative positional relationship within the first state.

[0075] For example, if the electronic device (101) does not include the above structure such as the opening (212a), one or more second image sensors (250-2) in the first state may not be exposed outside the housing, but in the second state, one or more second image sensors (250-2) may be exposed outside the housing.

[0076] Although not shown in FIGS. 2A, 2B, 2C, and 2D, the electronic device (101) 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 area (230a) and area (230b). For example, in the intermediate state, a portion of area (230b) may be exposed, and another portion (or a remaining portion) of area (230b) may be covered by the first housing (210) or rolled into the first housing (210). However, the present invention is not limited thereto.

[0077] Referring again to FIG. 1, the electronic device (101) may include structures for moving a second housing (e.g., the second housing (220) of FIG. 2A) of the electronic device (101) relative to a first housing (e.g., the first housing (210) of FIG. 2A). For example, the structures may be exemplified through the description of FIGS. 3A and 3B.

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

[0079] Referring to FIGS. 3A and 3B, the electronic device (101) may include a housing (200) including a first housing (210) and a second housing (220), a display (230), and a driving unit (360).

[0080] For example, the first housing (210) may include a first housing cover (311), a plate (212), and a frame cover (313).

[0081] For example, the first housing cover (311) may at least partially form a side portion of the outer surface of the electronic device (101). For example, the first housing cover (311) may at least partially form a rear portion of the outer surface. For example, the first housing cover (311) may include an opening (311a) for one or more second image sensors (250-2). For example, the first housing cover (311) may include a surface that supports the plate (212). For example, the first housing cover (311) may be coupled with the plate (212). For example, the first housing cover (311) may include a frame cover (313). For example, the first housing cover (311) may be coupled with the frame cover (313).

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

[0083] For example, the frame cover (313) may be at least partially covered by the first housing cover (311).

[0084] For example, the frame cover (313) can be at least partially wrapped by the display (230). For example, although the frame cover (313) is at least partially wrapped by the display (230), the position of the frame cover (313) can be maintained independently of the movement of the display (230). For example, the frame cover (313) can be arranged in relation to at least some of the components of the display (230). For example, the frame cover (313) can include rails (313a) that provide (or guide) a path for movement of at least one component of the display (230).

[0085] For example, the frame cover (313) may be coupled with at least one component of the electronic device (101). For example, the frame cover (313) may support a rechargeable battery (189). For example, the battery (189) may be supported through a recess or hole in a surface (313b) of the frame cover (313). For example, the frame cover (313) may be coupled with one end of a flexible printed circuit board (FPCB) (325) on a surface of the frame cover (313). 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 assembly (361) via the FPCB (325).

[0086] For example, the frame cover (313) can be combined with at least one structure of the electronic device (101) for a plurality of states including the first state and the second state. For example, the frame cover (313) can fix the motor assembly (361) of the driving unit (360).

[0087] For example, the second housing (220) may include a front cover (321) and a slide cover (322).

[0088] For example, the front cover (321) may be at least partially wrapped by the display (230). For example, the front cover (321) may be coupled with at least a portion of the first display area (231) of the display (230) that wraps the front cover (321), unlike the frame cover (313), such that the display (230) moves relative to the second housing (220) that moves relative to the first housing (210).

[0089] For example, the front cover (321) may be coupled with at least one component of the electronic device (101). For example, the front cover (321) may be coupled with a printed circuit board (PCB) (324) that includes components of the electronic device (101). For example, the PCB (324) may include a processor (120) (not shown in FIGS. 3A and 3B). For example, the front cover (321) may include one or more second image sensors (250-2).

[0090] For example, the front cover (321) can be combined with at least one structure of the electronic device (101) for a plurality of states including the first state and the second state. For example, the front cover (321) can fix the rack gear (363) of the driving unit (360).

[0091] For example, the front cover (321) can be combined with a slide cover (322).

[0092] For example, the slide cover (322) may be coupled with the front cover (321) to protect at least one component of the electronic device (101) coupled within the front cover (321) and / or at least one structure of the electronic device (101) coupled within the front cover (321). For example, the slide cover (322) may include a structure for the at least one component. For example, the slide cover (322) may include one or more openings (326) for one or more second image sensors (250-2). For example, the one or more openings (326) may be aligned with one or more second image sensors (250-2) disposed on the front cover (321). For example, the size of each of the one or more openings (326) may correspond to the size of each of the one or more second image sensors (250-2).

[0093] 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.

[0094] For example, the drive unit (360) may include a motor assembly (361), a pinion gear (362), and a rack gear (363).

[0095] For example, the motor assembly (361) may operate based on power from the battery (189). For example, the power may be provided to the motor assembly (361) in response to the user input defined above.

[0096] For example, the pinion gear (362) may be coupled to the motor assembly (361) via a shaft. For example, the pinion gear (362) may be rotated based on the motion of the motor assembly (361) transmitted via the shaft.

[0097] 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 be moved in the first direction (261) or the second direction (262) according to the rotation of the pinion gear (362). For example, the second housing (220) can be moved in the first direction (261) and the second direction (262) by the rack gear (363) that is moved according to the rotation of the pinion gear (362) due to the operation of the motor assembly (361). For example, the first state of the electronic device (101) 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 (220) in the second direction (262). For example, the second state of the electronic device (101) can be changed to a state different from the second state (e.g., one or more intermediate states or the first state) through the movement of the second housing (220) in the first direction (261). For example, the change of the first state to the second state by the driving unit (360) and the change of the second state to the first state by the driving unit (360) can be exemplified through FIGS. 4A and 4B.

[0098] 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.

[0099] Referring to FIGS. 4A and 4B, the motor assembly (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 assembly (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 front cover (321) within the second housing (220) secures the rack gear (363), the second housing (220) can be moved in the first direction (261) based at least in part on the movement of the rack gear (363) in the first direction (261). For example, since the front cover (321) within the second housing (220) is coupled to at least a portion of the first display area (231) of the display (230) and fixes the rack gear (363), the display (230) can be moved 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). 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 state (490) is changed to the state (495) which is the second state.

[0100] For example, the second display area (232) of the display (230) may be moved according to the movement of the display (230). For example, the second display area (232) may be moved through the space between the first housing cover (311) and the frame cover (313) when the state (490) is changed to the state (495) according to the user input defined above. For example, the second display area (232) in the state (495) may be exposed, unlike the second display area (232) that has entered the space in the state (490).

[0101] For example, the front cover (321) within the second housing (220) is coupled with the PCB (324) connected to the other end of the FPCB (325) and fixes the rack gear (363), so that the shape of the FPCB (325) can be changed when the state (490) is changed to the state (495).

[0102] The motor assembly (361) can be operated based at least in part on the defined user input received within the 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 assembly (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, since the front cover (321) within the second housing (220) secures the rack gear (363), the second housing (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, since the front cover (321) within the second housing (220) is coupled with at least a portion of the first display area (231) of the display (230) and fixes the rack gear (363), the display (230) can be moved at least in part based on the movement of the rack gear (363) in the second direction (262). For example, the display (230) can be moved along the rails (313a). 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 state (495) is changed to the state (490).

[0103] For example, the second display area (232) of the display (230) can be moved according to the movement of the display (230). For example, the second display area (232) can be moved through the space between the first housing cover (311) and the frame cover (313) when the state (495) is changed to the state (490) according to the user input defined above. For example, the second display area (232) in the state (490) can enter the space, unlike the second display area (232) exposed in the state (495).

[0104] For example, the front cover (321) within the second housing (220) is coupled with the PCB (324) connected to the other end of the FPCB (325) and fixes the rack gear (363), so that the shape of the FPCB (325) can be changed when the state (495) is changed to the state (490).

[0105] FIGS. 2A to 4B illustrate an electronic device (101) 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 (101) 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.

[0106] Figure 5a illustrates a portion of an exemplary electronic device. Figure 5b is a perspective view of a driving unit of the exemplary electronic device. Figure 5c is an exploded perspective view of a driving unit of the exemplary electronic device.

[0107] Referring to FIGS. 5A, 5B, and 5C, the electronic device (101) may include a housing (200) including a first housing (e.g., the first housing (210) of FIG. 2A) and a second housing (e.g., the second housing (220) of FIG. 2A) movably coupled to the first housing (210). The electronic device (101) may include a motor assembly (361) disposed within the housing (200) and a drive unit (e.g., the drive unit (360) of FIG. 3B) including a gear assembly (510). The motor assembly (361) may include a first shaft (501), a second shaft (502), a plurality of coils (520), a rotating member (530), and a vibrator (540).

[0108] According to one embodiment, the electronic device (101) may include a display (e.g., display (230) of FIG. 2a). The display (230) may include a first display area (e.g., first display area (231) of FIG. 2c) disposed on a second housing, and a second display area (e.g., second display area (232) of FIG. 2c) extending from the first display area (231) and at least partially recessed within the first housing (210) or visually exposed to the outside of the electronic device (101) according to movement of the second housing (220).

[0109] For example, the first display area (231) may be exposed to the outside of the electronic device (101). The first display area (231) may be a substantially flat area. For example, the first display area (231) may be an area of ​​the display (230) that does not deform. For example, the first display area (231) may be an area of ​​the display (230) that is visually exposed to the outside and has a fixed size.

[0110] For example, the second display area (232) may be connected to the first display area (231). The second display area (232) may be an area of ​​the display (230) that is deformable by the first housing (210) and / or the second housing (220). For example, the second display area (232) may be at least partially bent by at least a portion thereof entering the first housing (210). The second display area (232) may form a curved surface by at least a portion thereof entering the first housing (210). For example, the second display area (232) may be configured to change the size of the display (230) visually exposed to the outside of the electronic device (101) by at least a portion thereof entering the first housing (210) or by being exposed to the outside of the electronic device (101). For example, the electronic device (101) may include at least one gear (e.g., a pinion gear (362)) that provides a rotational axis (x1) for moving the second display area (232). The second display area (232) may be at least partially deformable by being bent about the rotational axis (x1) by the at least one gear. The display (230) may provide various user experiences to a user of the electronic device (101) by including the deformable second display area (232).

[0111] In one embodiment, the second housing (220) may be movably coupled to the first housing (210) between a retracted position and an extended position. It should be noted that when the second housing (220) is referred to as moving with respect to the first housing (210) in this document, this refers to the relative movement of the second housing (220) with respect to the first housing (210), and does not limit the actuation of the housing (200) of the electronic device (101) and / or the arrangement relationship between the second housing (220) and the first housing (210). For example, the second housing (220) moving with respect to the first housing (210) may mean the first housing (210) moving with respect to the second housing (220), depending on the relative viewpoint. For example, a second housing (220) moving in a first direction (261) with respect to a first housing (210) may be expressed as a first housing (210) moving in a second direction (262) opposite to the first direction (261) with respect to the second housing (220). A second housing (220) moving in a second direction (262) opposite to the first direction (261) with respect to the first housing (210) may be expressed as a first housing (210) moving in the first direction (261) with respect to the second housing (220). However, the above-mentioned embodiments are exemplary and are not limited thereto.

[0112] The first state of the electronic device (101) may be defined as a state in which the second display area (232) of the display (230) is inserted into the first housing (210) and the display area of ​​the display (230) that is visually exposed to the outside of the electronic device (101) has a minimum size (e.g., state (490) of FIG. 4a). The first state may be referred to as a slide-in state or a closed state. The second state of the electronic device (101) may be defined as a state in which the second display area (232) of the display (230) is exposed to the outside of the electronic device (101) and the display area of ​​the display (230) that is visually exposed to the outside of the electronic device (101) has a maximum size (e.g., state (230c) of FIG. 2c). The second state may be referred to as a slide-out state or an open state. For example, the first state may be a state in which the second housing (220) is movable in a first direction (261) with respect to the first housing (210). For example, the second state may be a state in which the second housing (220) is movable in a second direction (262) opposite to the first direction (261) with respect to the first housing (210). The first state may be referred to as a state in which the second housing (220) is in a retracted position with respect to the first housing (210), in that it is a state in which the display area of ​​the display (230) of the minimum size that is visually exposed to the outside of the electronic device (101). The second state may be referred to as a state in which the second housing (220) is in an extended position with respect to the first housing (210), in that it is a state in which the display area of ​​the display (230) of the maximum size that is visually exposed to the outside of the electronic device (101).

[0113] For example, although not shown, within an intermediate state between the first state and the second state, a portion of the second display area (232) may be exposed to the outside. The remainder of the second display area (232) may be disposed within the first housing (210). By allowing the second display area (232) to be deformed to fit within the first housing (210) or be exposed to the outside of the electronic device (101), the second display area (232) may be configured to provide a plurality of states to the electronic device (101).

[0114] For example, the second housing (220) may be coupled to the first housing (210) so as to be movable in a first direction (261) parallel to the y-axis with respect to the first housing (210) or in a second direction (262) opposite to the first direction (261). For example, the second housing (220) may be coupled to the first housing (210) so as to be slidable in a first direction (261) or in a second direction (262) opposite to the first direction (261) with respect to the first housing (210). For example, referring to FIGS. 2A, 2B, 2C, 2D, 4A, and 4B together, the second housing (220) may be slidably moved in a first direction (261) parallel to the y-axis with respect to the first housing (210) from a first state. The second housing (220) may be configured to change the electronic device (101) from the first state to the second state by moving the second housing (220) in the first direction (261) with respect to the first housing (210). For example, the second housing (220) may slide and move in a second direction (262) that is parallel to the y-axis and opposite to the first direction (261) with respect to the first housing (210) from the second state. The second housing (220) may be configured to change the electronic device (101) from the second state to the first state by moving the second housing (220) in the second direction (262) with respect to the first housing (210).

[0115] For example, referring to FIGS. 2A, 2B, and 4A together, the first display area (231) may be disposed on the second housing (220) and exposed to the outside. Within the first state, the second display area (232) may be disposed within the first housing (210). During the transition from the first state to the second state, since the second housing (220) moves in the first direction (261) with respect to the first housing (210), the first display area (231) may move along the second housing (220) in the first direction (261). Since the second display area (232) extends from the first display area (231), the second display area (232) may be exposed to the outside by moving along the first display area (231).

[0116] For example, referring to FIGS. 2C, 2D, and 4B together, within the second state, the second display area (232) can be exposed to the outside. During the transition from the second state to the first state, since the second housing (220) moves in a second direction (262) opposite to the first direction (261) with respect to the first housing (210), the first display area (231) can move along the second housing (220) in the second direction (262). Since the second display area (232) extends from the first display area (231), the second display area (232) can enter the first housing (210) by moving along the first display area (231).

[0117] In one embodiment, the electronic device (101) may include an actuator (509) (or a vibration motor assembly) for providing haptic feedback to a user. For example, the electronic device (101) may be configured to provide haptic feedback by controlling the actuator (509) to vibrate the actuator (509) based on a user input for haptic feedback. Because the actuator (509) is separate from the motor assembly (361), the electronic device (101) may have difficulty securing additional space for other electronic components within the electronic device (101). For example, the electronic device (101) may include one or more cameras (250). The one or more cameras (250) may include, for example, a first camera (251) and a second camera (252) arranged along an edge of a second housing (220) inside the housing (200). The electronic device (101) may be required to provide haptic feedback to a user while omitting the actuator (509) in order to secure space for another camera distinct from the first camera (251) and the second camera (252). Hereinafter, the structure of a driving unit (e.g., a driving unit (360) of FIG. 3B) (or a motor assembly (361)) for moving the second housing (220) relative to the first housing (210) and providing haptic feedback to the user is described.

[0118] In one embodiment, the motor assembly (361) may be disposed within the housing (200). For example, the motor assembly (361) may be driven based on power supplied to the motor assembly (361). The second housing (220) may be moved relative to the first housing (210) based on the driving of the motor assembly (361). For example, the motor assembly (361) may be fastened to the second housing (220) within the housing (200). The motor assembly (361) may be configured to move the second housing (220) relative to the first housing (210) by providing power to the first housing (210) through a gear assembly (510) coupled with the motor assembly (361). For example, the motor assembly (361) may be fastened to the first housing (210) within the housing (200). The motor assembly (361) may be configured to move the second housing (220) relative to the first housing (210) by providing power to the second housing (220) through a gear assembly (510) linked to the motor assembly (361). However, the present invention is not limited thereto. The position at which the motor assembly (361) is arranged within the housing (200) may be changed to meet the needs of the user. The position at which the motor assembly (361) is arranged will be described later with reference to FIGS. 9A and 9B.

[0119] In one embodiment, the gear assembly (510) may be coupled with the motor assembly (361) to move the second housing (220) relative to the first housing (210) in response to the driving of the motor assembly (361). For example, the gear assembly (510) may be disposed within the housing (200). The gear assembly (510) may include a plurality of intermeshing gears configured to move the second housing (220) relative to the first housing (210) in response to the driving of the motor assembly (361). Some of the plurality of gears (e.g., the rack gear (363)) may be fastened to the first housing (210). Some of the plurality of gears (e.g., the pinion gear (362)) that are engaged with some of the plurality of gears may be fastened to the second housing (220). By the driving force provided from the motor assembly (361), the plurality of gears that are interlocked with each other can be configured to move the second housing (220) relative to the first housing (210).

[0120] In one embodiment, the first shaft (501) may include a first end (e.g., the first end (501a) of FIG. 6A) coupled with a gear assembly (510), and a second end (501b) opposite the first end (501a). For example, the first shaft (501) may be capable of transmitting the driving force of the motor assembly (361) to a plurality of gears included in the gear assembly (510) by engaging at least a portion of the gear assembly (510). For example, the first shaft (501) may be a portion of the motor assembly (361) that connects (and / or engages) the motor assembly (361) and the gear assembly (510). For example, the first end (501a) of the first shaft (501) may be a portion of the first shaft (501) that engages the gear assembly (510). For example, a first end (501a) of a first shaft (501) may be coupled with a reducer (511) of a gear assembly (510). The first end (501a) may be positioned within the reducer (511). The first end (501a) of the first shaft (501) may be engaged or interlocked with at least some of the gears (e.g., the sun gear (610), the ring gear (620), and the plurality of planetary gears (630) of FIG. 6A) within the reducer (511), thereby providing a driving force to move the second housing (220) relative to the first housing (210). For example, a second end (501b) of the first shaft (501) may be positioned within a motor assembly (361). For example, the second end (501b) of the first shaft (501) may be disposed within the first motor housing (551) that is coupled with the gear assembly (510) (or reducer (511)) among the motor housings (550). For example, the second end (501b) of the first shaft (501) may be a portion configured to receive driving force of the motor assembly (361) from a rotating member (530) that is configured to rotate based on power supplied to the motor assembly (361).The first shaft (501) may be referred to as a driving shaft in that it is configured to move the second housing (220) relative to the first housing (210) through the driving force of the motor assembly (361), but is not limited thereto.

[0121] In one embodiment, the second shaft (502) can be separated from the first shaft (501). For example, the second shaft (502) can be spaced apart from the first shaft (501). The second shaft (502) can face the second end (501b) of the first shaft (501). For example, the second shaft (502) can be a portion that provides haptic feedback via the vibrator (540) based on power provided to the motor assembly (361). For example, the second shaft (502) can be rotated within the motor assembly (361) (or the motor housing (550)) based on power supplied to the motor assembly (361). The second shaft (502) may be configured to generate haptic feedback by rotating the vibrator (540) coupled to the second shaft (502) by rotating within the motor assembly (361). For example, the second shaft (502) may be configured to rotate independently of the first shaft (501) because it is separated from the first shaft (501). In a state where the second shaft (502) is independently rotatable with respect to the first shaft (501), the first shaft (501) may be configured to provide haptic feedback through the vibrator (540) regardless of movement of the first housing (210) with respect to the second housing (220) because it is separated from the second shaft (502). The second shaft (502) may be referred to as a vibration axis in that it is configured to provide haptic feedback through rotation, but is not limited thereto.

[0122] In one embodiment, the motor assembly (361) may include a motor housing (550) for housing components within the motor assembly (361). For example, the motor housing (550) may include a first motor housing (551) facing the gear assembly (510) (or the reducer (511)) and at least partially surrounding the first shaft (501), a second motor housing (552) coupled with the first motor housing (551), and a third motor housing (553) coupled with the second motor housing (552) and spaced apart from the first motor housing (551). The motor housing (550) may include a first motor cover (554) disposed between the first motor housing (551) and the reducer (511), and a second motor cover (555) opposite the first motor cover (554) and coupled to the third motor housing (553) so as to face the vibrator (540). The first motor housing (551), the second motor housing (552), and the third motor housing (553) may each provide a space for components within the motor assembly (361).

[0123] In one embodiment, the plurality of coils (520) may include a first coil (521) disposed along a first shaft (501) and one or more second coils (522) disposed along a second shaft (502). For example, the plurality of coils (520) may at least partially surround the first shaft (501) and the second shaft (502). For example, the plurality of coils (520) may be disposed along a surface of a motor housing (550). For example, the plurality of coils (520) may surround a rotating member (530) coupled to the second shaft (502). The plurality of coils (520) may be configured to cause rotation and / or movement of the rotating member (530) by interacting or cooperating with the rotating member (530) based on current flowing within the plurality of coils (520).

[0124] For example, the first coil (521) may be positioned within a first motor housing (551) in which the first shaft (501) is at least partially disposed. For example, one or more second coils (522) may be positioned within a second motor housing (552) and a third motor housing (553) in which the second shaft (502) is at least partially disposed. For example, the first motor housing (551) may include a first outer frame (551a) and a first inner frame (551b) disposed within the first outer frame (551a). The first coil (521) may be positioned between the first outer frame (551a) and the first inner frame (551b). The first inner frame (551b) may at least partially surround the first shaft (501). The first coil (521) can be separated from the first shaft (501) by the first internal frame (551b).

[0125] For example, the one or more second coils (522) may include a second coil (522a) and a third coil (522b) arranged along the second shaft (502) and / or the rotating member (530). For example, the second coil (522a) may be positioned within a second motor housing (552) coupled with a first motor housing (551). The second motor housing (552) may include a second outer frame (552a) and a second inner frame (552b) disposed within the second outer frame (552a). The second coil (522a) may be disposed between the second outer frame (552a) and the second inner frame (552b). The second inner frame (552b) may at least partially surround the second shaft (502). The second coil (522a) may be separated from the second shaft (502) (and / or the rotating member (530) coupled with the second shaft (502)) by the second inner frame (552b). For example, the third coil (522b) may be positioned within a third motor housing (553) coupled with the second motor housing (552). The third motor housing (553) may include a third outer frame (553a) and a third inner frame (553b) disposed within the third outer frame (553a). The third coil (522b) may be disposed between the third outer frame (553a) and the third inner frame (553b). The third inner frame (553b) may at least partially surround the second shaft (502). The third coil (522b) may be separated from the second shaft (502) (and / or the rotating member (530) coupled with the second shaft (502)) by the third internal frame (553b). However, the above-described embodiments are exemplary and are not limited thereto. For example, the motor housing (550) may be formed as an integral part.For example, the first motor housing (551), the second motor housing (552), the third motor housing (553), the first motor cover (554), and the second motor cover (555) may form a single motor housing (550) formed as an integral part. For example, the first motor housing (551), the second motor housing (552), and the third motor housing (553) may be parts where the coils (521, 522a, 522b) inside the motor housing (550) formed as an integral part are respectively disposed. However, the present invention is not limited thereto.

[0126] For example, the first coil (521) may be a coil for moving the rotating member (530) toward the first shaft (501) by interacting with the rotating member (530) among the plurality of coils (520). For example, the first coil (521) may form a magnetic field based on a current flowing in the first coil (521). The first coil (521) may be configured to move the rotating member (530) toward the first shaft (501) through a magnetic force with the rotating member (530) caused by the magnetic field formed by the first coil (521).

[0127] For example, one or more second coils (522) may be coils for rotating the rotating member (530) by interacting with the rotating member (530) among the plurality of coils (520). For example, one or more second coils (522) may form a magnetic field based on a current flowing in the one or more second coils (522). The one or more second coils (522) may be configured to rotate the rotating member (530) through the magnetic field formed by the one or more second coils (522).

[0128] In one embodiment, the rotating member (530) can be coupled with the second shaft (502) to rotate the second shaft (502) based on a current flowing in one or more second coils (522). The rotating member (530) can include a fastening hole (532a) configured to allow a second end (501b) of the first shaft (501) to be inserted therein. For example, the rotating member (530) can be penetrated by the second shaft (502). The rotating member (530) can surround at least a portion of the second shaft (502). For example, the rotating member (530) can be magnetic. The rotating member (530) can be configured to rotate the second shaft (502) coupled with the rotating member (530) by being rotated by a magnetic field formed based on a current flowing in one or more second coils (522).

[0129] For example, the rotating member (530) may be configured to be fastened to the first shaft (501) by being moved toward the first shaft (501) surrounded by the first coil (521) by a magnetic field formed based on a current flowing in the first coil (521). The fastening hole (532a) of the rotating member (530) may be formed toward the first shaft (501) to fasten the rotating member (530) moved by the first coil (521) to the first shaft (501). For example, the fastening hole (532a) may face the second end (501b) of the first shaft (501). The fastening hole (532a) may have a shape and / or structure for fastening to the second end (501b). Regarding the shape of the fastening hole (532a) for fastening to the second end (501b), it is described below in FIG. 8a.

[0130] According to one embodiment, the rotating member (530) may include a magnet (531) including a through hole (531a) that accommodates at least a portion of the second shaft (502), and a fastening member (532) attached to the magnet (531) toward the second end (501b) of the first shaft (501) and forming a fastening hole (532a). The first coil (521) may be configured to move the rotating member (530) through a magnetic force with the fastening member (532) based on a current flowing through the first coil (521). The one or more second coils (522) may be configured to rotate the rotating member (530) through a magnetic field formed by the magnet (531) based on a current flowing through the one or more second coils (522).

[0131] For example, the magnet (531) may be a part for rotating the rotating member (530) (or the second shaft (502)) by being rotated based on a current flowing in one or more second coils (522) among the rotating member (530). For example, the through hole (531a) may be at least partially penetrated by the second shaft (502). The through hole (531a) may have a shape corresponding to the shape of at least a portion of the second shaft (502) in order to rotate the second shaft (502) according to the rotation of the magnet (531), but is not limited thereto. For example, the fastening member (532) may be a portion of the rotating member (530) that moves toward the first shaft (501) based on the current flowing in the first coil (521) to couple the rotating member (530) to the second end (501b) of the first shaft (501). The fastening member (532) may include, but is not limited to, a magnetic material (e.g., metal) that receives a magnetic force by a magnetic field formed by the current flowing in the first coil (521). For example, the rotating member (530) may include, but is not limited to, an adhesive member (533) interposed between the fastening member (532) and the magnet (531) to attach the fastening member (532) to the magnet (531).

[0132] In one embodiment, the motor assembly (361) may include a stopper (503) slidably coupled to the first shaft (501) and in contact with the rotating member (530), and an elastic member (504) that urges the stopper (503) toward the rotating member (530). For example, the stopper (503) may surround at least a portion of the first shaft (501). The stopper (503) may be in contact with a fastening member (532) facing the second end (501b) of the first shaft (501). For example, the stopper (503) may be slidable relative to the first shaft (501) within the first motor housing (551). For example, the elastic member (504) may be configured to urge the stopper (503) toward the rotating member (530) within the first motor housing (551), thereby maintaining the stopper (503) in contact with the rotating member (530). For example, the elastic member (504) may at least partially surround the stopper (503) and / or the first shaft (501). The elastic member (504) may be positioned, for example, between the first motor cover (554) and the rotating member (530) to urge the stopper (503) toward the rotating member (530).

[0133] For example, based on the current flowing in the first coil (521), the rotating member (530) can be moved toward the first shaft (501) by the magnetic field formed by the first coil (521) and the magnetic force between the fastening member (532). The stopper (503) can compress the elastic member (504) by being moved by the fastening member (530) moving toward the first shaft (501). The fastening hole (532a) of the fastening member (532) can be fastened with the second end (501b) of the first shaft (501). For example, when the current flowing through the first coil (521) is bypassed and / or blocked, the stopper (503) can separate the rotating member (530) from the first shaft (501) by pressing the rotating member (530) by the restoring force of the elastic member (504). The fastening hole (532a) of the fastening member (532) can be separated from the second end (501b) of the first shaft (501) by the restoring force of the elastic member (504).

[0134] According to one embodiment, the second shaft (502) may include a first portion (502a) configured to be coupled with a rotating member (530), and a second portion (502b) connected to the first portion (502a) and configured to guide movement of the rotating member (530). For example, the first portion (502a) may be a portion configured to be coupled with a magnet (531). The second shaft (502) may be coupled with the magnet (531) through the first portion (502a), thereby being rotated by the rotation of the magnet (531). For example, the first portion (502a) may be coupled to a through hole (531a) of the magnet (531). The first portion (502a) may have a shape corresponding to the shape of the through hole (531a), but is not limited thereto. For example, the second portion (502b) can at least partially penetrate the magnet (531). The second portion (502b) can be inserted into the through hole (531a) of the magnet (531). For example, the second portion (502b) can guide the movement of the magnet (531) relative to the first shaft (501) by at least partially penetrating the magnet (531). The magnet (531) can be rotatable relative to the second portion (502b).

[0135] In one embodiment, a vibrator (540) can be coupled to the second shaft (502) to provide haptic feedback (e.g., haptic feedback (600) of FIG. 6A) based on rotation of the second shaft (502). For example, the vibrator (540) can be spaced apart from the rotating member (530). The vibrator (540) can be positioned outside of a motor housing (550) in which the rotating member (530) is positioned. For example, the vibrator (540) can be disposed at one end of the second shaft (502). The vibrator (540) can generate vibration by rotating together with the second shaft (502). For example, the second shaft (502) can include a third portion (502c) for engaging with the vibrator (540). The vibrator (540) may include a coupling hole (541) into which the third part (502c) is inserted. The coupling hole (541) may have a shape corresponding to the shape of the third part (502c), but is not limited thereto. According to one embodiment, the second shaft (502) may pass through the second motor cover (555) and be coupled to the vibrator (540). According to one embodiment, the motor assembly (361) may include a coupling pin (545) that is coupled to the third part (502c) of the second shaft (502) to reduce the detachment of the vibrator (540) from the third part (502c).

[0136] In one embodiment, the gear assembly (510) may include a reducer (511) that reduces a rotational speed of a second shaft (502) by engaging a first end (501a) of a first shaft (501). The gear assembly (510) may include a pinion gear (362) connected to the reducer (511), and a rack gear (363) that engages with the pinion gear (362) and is disposed within the housing (200) along a direction of movement of the second housing (220) relative to the first housing (210) so as to move the second housing (220) relative to the first housing (210) in accordance with rotation of the pinion gear (362).

[0137] For example, the gear assembly (510) may include a third shaft (512) connecting a pinion gear (362) and a plurality of gears within the reducer (511). For example, the reducer (511) may mesh with the first shaft (501) through the plurality of gears within the reducer (511). When the first shaft (501) rotates together with the second shaft (502) by the rotating member (530), the rotational speed of the third shaft (512) connected to the pinion gear (362) may be lower than the rotational speed of the first shaft (501) through the gear ratio between the plurality of gears within the reducer (511). Through the above gear ratio, since the rotation speed of the pinion gear (362) is smaller than the rotation speed of the first shaft (501), the driving force for moving the second housing (220) relative to the first housing (210) by the pinion gear (362) meshing with the rack gear (363) can relatively increase.

[0138] For example, the second shaft (502) may be rotated by the rotating member (530) to provide a rotation axis (x1) of the vibrator (540). The rotation axis (x1) may correspond to the rotation axis of the first shaft (501), the third shaft (512), and / or the pinion gear (362) by the rotating member (530) when the rotating member (530) is coupled to the first shaft (501) through the fastening hole (532a). For example, the second shaft (502) may be configured to rotate the vibrator (540) coupled to the second shaft (502) in the first rotation direction (411) and / or the second rotation direction (412) by being rotated by the rotating member (530) in the first rotation direction (411) and / or the second rotation direction (412) opposite to the first rotation direction. When the above-mentioned rotating member (530) is connected to the second end (501b) of the first shaft (501) through the connecting hole (532a), the first shaft (501) and the pinion gear (362) can be rotated in the first rotation direction (411) and the second rotation direction (412). For example, the rack gear (363) fastened to the second housing (220) may be configured to move the second housing (220) in a first direction (261) relative to the first housing (210) by rotation of the pinion gear (362) in the first rotational direction (411), or to move the second housing (220) in a second direction (262) opposite to the first direction (261) relative to the first housing (210) by rotation of the pinion gear (362) in a second rotational direction (412) opposite to the first rotational direction (411). However, the above-described embodiment is exemplary and is not limited thereto.

[0139] According to one embodiment, the motor assembly (361) can include a first set of magnetic elements (561) and a second set of magnetic elements (562) disposed between a rotating member (530) and one or more second coils (522). The first set of magnetic elements (561) can be at least partially disposed between a magnet (531) of the rotating member (530) and a second coil (522a). The first set of magnetic elements (561) can have different magnetic poles based on a current flowing through the second coil (522a). The second set of magnetic elements (562) can be at least partially disposed between the magnet (531) and a third coil (522b). The second set of magnetic elements (562) may have different magnetic poles based on the current flowing through the third coil (522b). The second set of magnetic elements (562), together with the first set of magnetic elements (561), may be configured to rotate the rotating element (530) through magnetic force with a plurality of magnetic poles of the magnet (531) (e.g., a plurality of magnetic poles (730) of FIG. 7A).

[0140] For example, the first set of magnetic members (561) may be disposed within a second motor housing (552) in which the second coil (522a) is positioned. The first set of magnetic members (561) may be separated from the second coil (522a) by a second internal frame (552b) of the second motor housing (552). The first set of magnetic members (561) may at least partially surround the magnet (531) within the second motor housing (552). For example, the second set of magnetic members (562) may be disposed within a third motor housing (553) in which the third coil (522b) is positioned. The second set of magnetic members (562) may be separated from the third coil (522b) by a third internal frame (553b) of the third motor housing (553). The second set of magnetic members (562) may at least partially surround the magnet (531) within the third motor housing (553).

[0141] For example, the first set of magnetic elements (561) and the second set of magnetic elements (562) may be arranged to rotate the magnet (531) based on current flowing in the second coil (522a) and the third coil (522b), respectively. For example, the first set of magnetic elements (561) may include a first magnetic element (561a) having different magnetic poles based on current flowing in the second coil (522a), and a second magnetic element (561b) facing the first magnetic element (561a). The second set of magnetic elements (562) may include a third magnetic element (562a) having different magnetic poles based on current flowing in the third coil (522b), and a fourth magnetic element (562b) facing the third magnetic element (562a). For example, the second magnetic member (561b) may be attached to the third magnetic member (562a). When the current flow direction of the current flowing in the second coil (522a) is changed, the magnetic poles of the first magnetic member (561a) and the second magnetic member (561b) may be changed. When the current flow direction of the current flowing in the third coil (522b) is changed, the magnetic poles of the third magnetic member (562a) and the fourth magnetic member (562b) may be changed. As the direction of the current flowing in the second coil (522a) and the third coil (522b) changes, the magnetic poles of the first set of magnetic elements (561) and the second set of magnetic elements (562) change, so that the magnet (531) can be rotated by the magnetic force between the first set of magnetic elements (561) and the second set of magnetic elements (562). The rotation of the magnet (531) by the first set of magnetic elements (561) and the second set of magnetic elements (562) will be described later in FIG. 7a and below.The motor assembly (361) can provide driving force of the second housing (220) to the first housing (210) through the separation structure of the first shaft (501) and the second shaft (502) and the moving structure of the rotating member (530), while also providing haptic feedback through the vibrator (540). Since the motor assembly (361) provides the haptic feedback, the actuator (509) for the haptic feedback in the electronic device (101) can be omitted. By omitting the actuator (509), the electronic device (101) can provide additional space for other electronic components (e.g., one or more cameras (250)) in the electronic device (101) and increase space efficiency in the electronic device (101).

[0142] Although the motor assembly (361) has been described as being rotated and / or moved by a plurality of coils (520) and magnetic members (561, 562), it is not limited thereto. The rotating member (530) may be configured to rotate and / or move the second shaft (502) relative to the first shaft (501) or the first shaft (501) relative to the second shaft (502) through various structures (or methods) for rotating and / or moving the rotating member (530) in addition to rotating and / or moving through magnetic force and / or electromagnetic induction.

[0143] According to one embodiment, the electronic device (101) may include a flexible printed circuit board (580) (e.g., FPCB (325) of FIG. 3A) for supplying power to the motor assembly (361). The flexible printed circuit board (580) may, for example, electrically connect another PCB of the electronic device (101) (e.g., PCB (324) of FIG. 3A) and the motor assembly (361). For example, a processor of the electronic device (101) (e.g., processor (120) of FIG. 1) may be configured to control the supply of power to the motor assembly (361) through the flexible printed circuit board (580) or to control the flow of current of the plurality of coils (520). For example, the flexible printed circuit board (580) may include a structure for being coupled to the motor housing (550). The flexible printed circuit board (580) may include, for example, first fastening holes (585a) into which first protrusions (556a) of the first motor housing (551) are inserted, second fastening holes (585b) into which second protrusions (556b) of the second motor housing (552) are inserted, and third fastening holes (585c) into which third protrusions (556c) of the third motor housing (553) are inserted. The flexible printed circuit board (580) may be referred to as a rigid flexible printed circuit board (RFPCB) in that it includes a portion having relatively high rigidity for being coupled with the motor housing (550), but is not limited thereto.

[0144] According to one embodiment, the electronic device (101) may include a fastening structure (590) for fixing the position of the motor assembly (361) (or the driving unit (360)) within the housing (200). The fastening structure (590) may accommodate the pinion gear (362) of the gear assembly (510). For example, the fastening structure (590) may be fastened to the second housing (220) when the rack gear (363) is fastened to the first housing (210). For example, the fastening structure (590) may be fastened to the first housing (210) when the rack gear (363) is fastened to the second housing (220). For example, the fastening structure (590) may be coupled to the reducer (511). The above-mentioned fastening structure (590) may include guide structures for guiding the direction of movement of the rack gear (363) that moves according to the rotation of the pinion gear (362), but is not limited thereto.

[0145] According to the above-described embodiment, the electronic device (101) can increase space efficiency within the electronic device (101) by being configured to provide haptic feedback through a motor assembly (361) for moving the first housing (210) relative to the second housing (220). The motor assembly (361) includes a structure in which a first shaft (501) for driving the second housing (220) and a second shaft (502) for providing haptic feedback through a vibrator (540) are separated, thereby being configured to provide the haptic feedback to the user or move the second housing (220) relative to the first housing (210) according to a user input. The above motor assembly (361) includes a rotating member (530) that is rotated or moved by a plurality of coils (520), thereby providing a state in which the second shaft (502) can rotate with respect to the first shaft (501) and a state in which the first shaft (501) can rotate together with the second shaft (502). A description related to a change in state according to the movement of the rotating member (530) will be described later with reference to FIGS. 6A and 6B.

[0146] Fig. 6a is a cross-sectional view of the driving unit of an exemplary electronic device in a disengaged state taken along line A-A' of Fig. 5b. Fig. 6b is a cross-sectional view of the driving unit of an exemplary electronic device in a engaged state taken along line A-A' of Fig. 5b.

[0147] Referring to FIGS. 6A and 6B, the electronic device (101) may include a housing (200) including a first housing (e.g., the first housing (210) of FIG. 2A) and a second housing (220) movably coupled with respect to the first housing (210). The electronic device (101) may include a motor assembly (361) disposed within the housing (200). The electronic device (101) may include a gear assembly (510) interlocked with the motor assembly (361) to move the second housing (220) with respect to the first housing (210) in accordance with the driving of the motor assembly (361). The motor assembly (361) may include a first shaft (501) having a first end (501a) coupled with the gear assembly (510) and a second end (501b) opposite the first end (501a). The motor assembly (361) may include a second shaft (502) separated from the first shaft (501). The motor assembly (361) may include a plurality of coils (520) including a first coil (521) disposed along the first shaft (501) and one or more second coils (522) disposed along the second shaft (502). The motor assembly (361) may include a rotating member (530) coupled with the second shaft (502) to rotate the second shaft (502) based on a current flowing through the one or more second coils (522), and including a fastening hole (532a) configured to allow the second end (501b) of the first shaft (501) to be inserted therein. The motor assembly (361) may include a vibrator (540) coupled to the second shaft (502) to provide haptic feedback (600) based on the rotation of the second shaft (502).

[0148] For example, the rotating member (530) may include a magnet (531) including a through hole (531a) that accommodates at least a portion of the second shaft (502), and a fastening member (532) that is attached to the magnet (531) toward the second end (501b) of the first shaft (501) and forms a fastening hole (532a). For example, the one or more second coils (522) may include a second coil (522a) and a third coil (522b) arranged along the magnet (531). For example, the motor assembly (361) may include a first set of magnetic elements (561) at least partially disposed between the magnet (531) and the second coil (522a), and a second set of magnetic elements (562) at least partially disposed between the magnet (531) and the third coil (522b).

[0149] For example, the motor assembly (361) may include a stopper (503) coupled with the first shaft (501) and in contact with a rotating member (530) and an elastic member (504) that presses the stopper (503) toward the rotating member (530). For example, the gear assembly (510) may include a reducer (511) that reduces the rotational speed of the second shaft (502) by engaging with the first end (501a) of the first shaft (501), a pinion gear (362) connected to the reducer (511), and a rack gear (363) that is configured to move the second housing (220) relative to the first housing (210) according to the rotation of the pinion gear (362) by engaging with the pinion gear (362).

[0150] In the following, redundant descriptions of configurations having the same reference numerals as those described in FIGS. 5a, 5b, and 5c are omitted.

[0151] Referring to FIGS. 6A and 6B, the rotating member (530) can provide a disengaged state and a engaged state by moving relative to the first shaft (501) based on the current flowing in the first coil (521). The disengaged state may be a state in which the second end (501b) of the first shaft (501) is separated from the engaging hole (532a) so that the second shaft (502) can rotate relative to the first shaft (501) to provide haptic feedback (600) via the vibrator (540). The above-described fastening state may be a state in which the second end (501b) of the first shaft (501) is inserted into the fastening hole (532a) so that the first shaft (501) can rotate with respect to the second shaft (502) to move the second housing (220) with respect to the first housing (210) by moving the rotating member (530) with respect to the first shaft (501).

[0152] For example, the disengaged state of the electronic device (101) may be a state in which the rotating member (530) is spaced apart from the first shaft (501) (or the second end (501b) of the first shaft (501). For example, the disengaged state may be a state in which the second shaft (502), which is coupled to the rotating member (530) by the first shaft (501) being positioned outside the engaging hole (532a), can rotate independently of the first shaft (501) according to the rotation of the rotating member (530). For example, the disengaged state may be a state in which the second shaft (502) among the first shaft (501) and the second shaft (502) can rotate based on the power provided to the motor assembly (361). For example, the disengaged state may be a state in which no current flows through the first coil (521). For example, the disengaged state may be a state in which haptic feedback (600) can be provided through a vibrator (540) coupled with the first shaft (501) by rotation of the first shaft (501). For example, the disengaged state may be a state in which the rotating member (530) is engaged with the first part (502a) of the second shaft (502). The disengaged state may be a state in which, for example, the through hole (531a) of the magnet (531) of the rotating member (530) is engaged with the first part (502a) of the second shaft (502), thereby allowing the second shaft (502) to rotate by rotation of the rotating member (530). The second shaft (502) can provide haptic feedback (600) through a vibrator (540) coupled to the second shaft (502) (or the rotating portion (502a) of the second shaft (502)) in the released state. For example, the released state can be referred to as a third state of the electronic device (101) in that the release of the rotating member (530) and the first shaft (501) is achieved and the rotating member (530) and the second shaft (502) are engaged.

[0153] For example, the fastening state of the electronic device (101) may be a state in which the rotating member (530) is coupled with the first shaft (501) (or the second end (501b) of the first shaft (501). For example, the fastening state may be a state in which the first shaft (501) is at least partially positioned inside the fastening hole (532a) so that the first shaft (501) coupled with the rotating member (530) can rotate according to the rotation of the rotating member (530). For example, the fastening state may be a state in which the first shaft (501) can rotate with respect to the second shaft (502) based on the power provided to the motor assembly (361). For example, the fastening state may be a state in which the rotating member (530) is separated from the first portion (502a) of the second shaft (502) by moving along the second portion (502b) of the second shaft (502). The above-described rotating member (530) may be rotatable relative to the second portion (502b) because it is spaced apart from the first portion (502a). Since the above-described rotating member (530) is rotatable relative to the second shaft (502), the above-described rotating member (530) may be configured to rotate the first shaft (501) coupled with the above-described rotating member (530) relative to the second shaft (502). For example, the engaged state may be a state in which current flows through the first coil (521). The electronic device (101) may be configured to maintain the engaged state while current flows through the first coil (521). For example, the fastening state may be a state in which the second shaft (502) is fastened to the rotary member (530) through the fastening hole (532a), and the first shaft (501) rotates according to the rotation of the rotary member (530), thereby allowing the second housing (220) to move relative to the first housing (210).For example, the fastening state may be referred to as the fourth state of the electronic device (101) in that the rotating member (530) and the first shaft (501) are fastened and the fastening of the rotating member (530) and the second shaft (502) is released. However, the above-mentioned embodiments are exemplary and are not limited thereto.

[0154] For example, referring to FIG. 6A, current may flow through at least one second coil (or one or more second coils) (522) in a disengaged state. The at least one second coil (522) may be configured such that the direction of the current flowing through the at least one second coil (522) is changed through a power management circuit (e.g., the power management circuit (1010) of FIG. 10) controlled by a processor (e.g., the processor (120) of FIG. 1) of the electronic device (101). As the direction of the current flowing through the at least one second coil (522) is changed, the stimulation of the fastening members (561, 562) surrounded by the at least one second coil (522) may be changed, respectively. As the stimuli of the above-described fastening members (561, 562) are each different, the magnet (531) of the rotating member (530) surrounded by the fastening members (561, 562) can rotate the rotating member (530) through the magnetic force with the fastening members (561, 562). The second shaft (502) coupled to the rotating member (530) through the through-hole (531a) of the magnet (531) can be rotated in the first rotation direction (411) and the second rotation direction (412) opposite to the first rotation direction (411) through the rotating rotating member (530). The vibrator (540) coupled to the second shaft (502) can provide haptic feedback (600) by rotating along the second shaft (502) in the first rotation direction (411) and the second rotation direction (412).

[0155] For example, the processor (120) may be configured to adjust the intensity of the current flowing through at least one second coil (522) and / or the change period of the direction in which the current flows through the power management circuit (1010) within the unlocked state. By adjusting the intensity of the current flowing through the at least one second coil (522) and / or the change period of the direction in which the current flows, the rotational speed and / or the rotational cycle of the rotating member (530), the second shaft (502), and / or the vibration generation cycle may be changed. By changing the rotational speed and / or the rotational cycle of the vibrator (540), the vibrator (540) may be configured to provide various haptic patterns (601, 602, 603, 604) to the user. For example, the processor (120) may be configured to provide haptic feedback (600) through the rotating member (530) or move the second housing (220) relative to the first housing (210) by adjusting the intensity of current flowing to at least one second coil (522) through the power management circuit (1010) within the disengaged state. However, the above-mentioned embodiments are exemplary and not limited thereto.

[0156] For example, when sequentially referring to FIGS. 6A and 6B, the electronic device (101) can change from a disengaged state to a engaged state. Based on the current flowing through the first coil (521), the rotating member (530) can move in the third direction (263) through the magnetic field formed by the first coil (521) and the magnetic force between the engaging member (532). By moving in the third direction (263), the rotating member (530) can press the stopper (503) that at least partially surrounds the first shaft (501) and the elastic member (504) that supports the stopper (503) in the third direction (263). The fastening hole (532a) of the fastening member (532) arranged toward the first shaft (501) can be coupled with the second end (501b) of the first shaft (501) by moving in the third direction (263). The through hole (531a) of the magnet (531) can be moved to rotate with respect to the second shaft (502) by being spaced apart from the first portion (502a) of the second shaft (502). While current flows through the first coil (521), the fastening state can be maintained by the magnetic field formed by the first coil (521).

[0157] For example, referring to FIG. 6B, a current may flow through at least one second coil (522) within a fastening state. As the direction of the current flowing through the at least one second coil (522) changes, the magnetic poles of the fastening members (561, 562) surrounded by the at least one second coil (522) may each change. As the magnetic poles of the fastening members (561, 562) change, the magnet (531) of the rotating member (530) surrounded by the fastening members (561, 562) may rotate the rotating member (530) through a magnetic force with the fastening members (561, 562). The first shaft (501) coupled with the rotating member (530) through the fastening hole (532a) of the fastening member (532) attached to the magnet (531) can be rotated in a first rotation direction (411) and a second rotation direction (412) opposite to the first rotation direction (411) through the rotating rotating member (530). The pinion gear (362) of the gear assembly (510) coupled and / or linked with the first end (501a) of the first shaft (501) can be rotated in the first rotation direction (411) and the second rotation direction (412) based on the rotation of the first shaft (501). The rack gear (363) meshed with the pinion gear (362) can move the second housing (220) in a first direction (261) and a second direction (262) opposite to the first direction (261) with respect to the first housing (210) according to the rotation of the pinion gear (362) in the first rotation direction (411) and the second rotation direction (412).For example, when the rack gear (363) is fastened to the second housing (220) and the motor assembly (361) and pinion gear (362) are fastened to the first housing (210), the rack gear (363) moves in the first direction (261) according to the rotation of the pinion gear (362) in the first rotational direction (411), thereby moving the second housing (220) fastened to the rack gear (363) in the first direction (261) with respect to the first housing (210). The above rack gear (363) can move in a second direction (262) opposite to the first direction (261) according to rotation of the pinion gear (362) in a second rotation direction (412) opposite to the first rotation direction (411), thereby moving the second housing (220) connected to the rack gear (363) in the second direction (262) with respect to the first housing (210). However, the above-mentioned embodiments are exemplary and are not limited thereto.

[0158] For example, referring sequentially to FIGS. 6B and 6A, the electronic device (101) can change from a fastened state to an unfastened state. Based on the first coil (521) in which the current flow is bypassed and / or blocked, the rotating member (530) can be moved in the fourth direction (264) by the elastic member (504) that presses the rotating member (530) in the fourth direction (264) opposite to the third direction (263) by the restoring force, and the stopper (503). By being moved in the fourth direction (264), the rotating member (530) can be separated from the first shaft (501). The fastening hole (532a) of the fastening member (532) arranged toward the first shaft (501) can be separated from the second end (501b) of the first shaft (501) by moving in the fourth direction (264). The through hole (531a) of the magnet (531) can be moved to rotate the second shaft (502) by being fastened to the first part (502a) of the second shaft (502) by rotation of the magnet (531). The unfastened state can be maintained while no current flows through the first coil (521).

[0159] According to one embodiment, the reducer (511) of the gear assembly (510) may be engaged with the first end (501a) of the first shaft (501). The reducer (511) may be configured to adjust and / or control the rotational speed of the third shaft (512) so that the rotational speed of the third shaft (512), which is connected to the reducer (511) and configured to rotate the pinion gear (362) in a fastened state in which the rotating member (530) is fastened with the first shaft (501), is less than the rotational speed of the first shaft (501). The reducer (511) may provide a driving force for moving the second housing (220) relative to the first housing (210) through the rotation of the third shaft (512) obtained based on the rotation of the first shaft (501). The above reducer (511) may be referred to as a gear box in that it includes a plurality of gears that mesh with the first end (501a) of the first shaft (501), but is not limited thereto.

[0160] For example, the gear assembly (510) may include a sun gear (610) for changing the rotational speed of the second shaft (502) within a fastened state, a ring gear (620) surrounding the sun gear (610), a plurality of planetary gears (630) meshed between the sun gear (610) and the ring gear (620), and a wheel (640) configured to be coupled with each of the plurality of planetary gears (630) and rotate together with the plurality of planetary gears (630). For example, a first end (501a) of a first shaft (501) may be coupled to a sun gear (610). A rotational speed of the first shaft (501) may correspond to a rotational speed of the sun gear (610). For example, a third shaft (512) of the gear assembly (510) may extend from a pinion gear (362) to a wheel (640). The rotation speed of the wheel (640) and the third shaft can correspond to the rotation speed of the pinion gear (362). When the rotating member (530) rotates in the fastened state, the sun gear (610) coupled with the first end (501a) of the first shaft (501) can rotate. The planetary gears (631, 632, 633, 634) meshed with the sun gear (610) can rotate between the sun gear (610) and the ring gear (620) with respect to the sun gear (610), respectively. The wheel (640) coupled with each of the planetary gears (631, 632, 633, 634) can rotate the third shaft (512) and the pinion gear (362) by rotating together with the planetary gears (631, 632, 633, 634). Due to the gear ratio of the sun gear (610) and the ring gear (620), the rotation speed of the pinion gear (362) may be lower than the rotation speed of the first shaft (501). For example, in a fastened state, the first shaft (501) may cause the rotation of the third shaft (512) linked with the reducer (511).Due to the gear ratio of the sun gear (610) and the ring gear (620), the rotation speed of the third shaft (512) in the engagement state in which the rotating member (530) is engaged with the first shaft (501) may be lower than the rotation speed of the first shaft (501) in the engagement state.

[0161] According to one embodiment, the motor assembly (361) may include a first region (361a) in which a first coil (521) is disposed, and a second region (361b) in which one or more second coils (522) are disposed. The rotating member (530) may be positioned within the second region (361b) in a disengaged state. The rotating member (530) may be partially positioned within the first region (361a) by sliding within the motor assembly (361) while changing from the disengaged state to the engaged state.

[0162] For example, the first region (361a) may be a region where the first motor housing (551) and the first motor cover (554) are located among the motor housings (550). The second region (361b) may be a region where the second motor housing (552), the third motor housing (553), and the second motor cover (555) are located among the motor housings (550).

[0163] For example, referring to FIG. 6A, in the disengaged state, the rotating member (530) may be positioned within the second motor housing (552) and the third motor housing (553) by the stopper (503) and the elastic member (504). The rotating member (530) may be surrounded by at least one second coil (522). The rotating member (530) may be at least partially surrounded by magnetic members (561, 562). For example, referring to FIGS. 6A and 6B sequentially, the rotating member (530) may slide in the third direction (263) within the motor housing (550) based on the current flowing in the first coil (521). Among the rotating member (530), at least a portion of the fastening member (532) and the magnet (531) may be positioned within the first motor housing (551). Since the fastening member (532) including the fastening hole (532a) is positioned within the first motor housing (551), the fastening hole (532a) can be fastened to the first shaft (501) within the first motor housing (551). For example, referring to FIGS. 6B and 6A sequentially, based on the first coil (521) in which the flow of current is bypassed and / or blocked, the rotating member (530) can slide in a fourth direction (264) opposite to the third direction (263) by the restoring force of the elastic member (504). The rotating member (530) can be positioned within the second motor housing (552) and the third motor housing (553) by sliding in the fourth direction (264). However, the above-described embodiments are exemplary and are not limited thereto.

[0164] In one embodiment, the rotating member (530) can be slidably coupled to the second shaft (502) within the motor assembly (361). For example, the magnet (531) of the rotating member (530) can include a through hole (531a) that receives the second shaft (502) and is slidable relative to the second shaft (502). For example, since the through hole (531a) is slidable relative to the second shaft (502), the rotating member (530) can be slidable relative to the second shaft (502) within the motor housing (550) in a third direction (263) and a fourth direction (264) opposite to the third direction.

[0165] According to one embodiment, the first shaft (501) and the second shaft (502) may be concentric with each other. For example, the rotational axis (x1) of the second shaft (502) may correspond to the rotational axis (x2) of the first shaft (501). For example, the rotational axis of the vibrator (540) and / or the rotational member (530) provided by the second shaft (502) may correspond to the rotational axis of the sun gear (610) provided by the first shaft (501). For example, the rotational axis (x1) of the second shaft (502) and the rotational axis (x2) of the first shaft (501) may correspond to the moving axis of the rotational member (530). Since the first shaft (501) and the second shaft (502) are concentric, the rotating member (530) can be configured to provide a disengaged state and a engaged state through axial movement (e.g., movement in the third direction (263) and the fourth direction (264)).

[0166] In one embodiment, the vibrator (540) may include a mass that is eccentric with respect to the second shaft (502). For example, the vibrator (540) may have a mass that is eccentric with respect to the rotational axis (x1) of the second shaft (502). Because the vibrator (540) is eccentric with respect to the rotational axis (x1) of the second shaft (502), the vibrator (540) may be configured to provide haptic feedback (600) by rotation of the second shaft (502). For example, the vibrator (540) may be referred to as an eccentric weight, but is not limited thereto.

[0167] According to the above-described embodiment, the electronic device (101) can provide various user experiences by including a motor assembly (361) configured to provide a disengaged state capable of providing haptic feedback (600) based on the rotation of the second shaft (502) and a movable state of the second housing (220) relative to the first housing (210) based on the rotation of the first shaft (501). The electronic device (101) can improve space efficiency for arranging other electronic components within the electronic device (101) by providing the haptic feedback (600) through the motor assembly (361).

[0168] Fig. 7a illustrates a driving unit of an exemplary electronic device. Figs. 7b, 7c, and 7d are partial cross-sectional views of the driving unit of the exemplary electronic device taken along lines BB' and C-C' of Fig. 7a.

[0169] Referring to FIG. 7A, the electronic device (101) may include a housing (200) including a first housing (e.g., the first housing (210) of FIG. 2A) and a second housing (220) movably coupled with respect to the first housing (210). The electronic device (101) may include a motor assembly (361) disposed within the housing (200). The electronic device (101) may include a gear assembly (510) linked with the motor assembly (361) to move the second housing (220) with respect to the first housing (210) in accordance with the driving of the motor assembly (361). The motor assembly (361) may include a first shaft (e.g., the first shaft (501) of FIG. 5c) having a first end coupled with the gear assembly (510) (e.g., the first end (501a) of FIG. 6a) and a second end opposite the first end (501a) (e.g., the second end (501b) of FIG. 5c). The motor assembly (361) may include a second shaft (502) separated from the first shaft (501). The motor assembly (361) may include a plurality of coils (e.g., the plurality of coils (520) of FIG. 5c) including a first coil (e.g., the first coil (521) of FIG. 5c) disposed along the first shaft (501) and one or more second coils (522) disposed along the second shaft (502). The motor assembly (361) may include a rotating member (530) coupled with the second shaft (502) to rotate the second shaft (502) based on a current flowing through the one or more second coils (522), and including a fastening hole (e.g., fastening hole (532a) of FIG. 5C) into which the second end (501b) of the first shaft (501) is inserted. The motor assembly (361) may include a vibrator (540) coupled to the second shaft (502) to provide haptic feedback (600) based on the rotation of the second shaft (502).The above-described rotating member (530) can provide a disengaged state and a engaged state by moving with respect to the first shaft (501) based on the current flowing in the first coil (521). The disengaged state may be a state in which the second end (501b) of the first shaft (501) is separated from the engaging hole (532a) so that the second shaft (502) can rotate with respect to the first shaft (501) to provide haptic feedback (e.g., haptic feedback (600) of FIG. 6A) through the vibrator (540). The above-described fastening state may be a state in which the second end (501b) of the first shaft (501) is inserted into the fastening hole (532a) so that the first shaft (501) can rotate relative to the second shaft (502) to move the second housing (220) relative to the first housing (210).

[0170] For example, the motor assembly (361) may include a first region (361a) in which a first coil (521) is disposed and a second region (361b) in which one or more second coils (522) are disposed. For example, the gear assembly (510) may include a reducer (511), a pinion gear (362), a rack gear (363) meshed with the pinion gear (362), and a third shaft (512) connecting the pinion gear (362) and the reducer (511). For example, the rotating member (530) may include a magnet (531). For example, the one or more second coils (522) may include a second coil (522a) and a third coil (522b). For example, the motor assembly (361) may include magnetic elements (561, 562) configured to rotate the magnet (531) by having different excitations based on the current flowing through one or more second coils (522).

[0171] In one embodiment, the magnet (531) may include a plurality of magnetic poles (730). A first set of magnetic elements (561) may be disposed between the magnet (531) and a second coil (522a). The first set of magnetic elements (561) may have different magnetic poles based on a current flowing through the second coil (522a). The second set of magnetic elements (562) may be disposed between the magnet (531) and a third coil (522b). The second set of magnetic elements (562) may be configured to rotate the rotating element (530) through magnetic force with the plurality of magnetic elements (730) of the magnet (531) together with the first set of magnetic elements (561) by having different magnetic poles based on the current flowing through the third coil (522b).

[0172] For example, the first set of magnetic members (561) may include a first magnetic member (561a) and a second magnetic member (561b) that are paired with each other. The first magnetic member (561a) may include first claws (710). The second magnetic member (561b) may include second claws (720) that are interlocked with the first claws (710). For example, the second set of magnetic members (562) may include a third magnetic member (562a) and a fourth magnetic member (562b) that are paired with each other. The third magnetic member (562a) may include third claws (750). The fourth magnetic member (562b) may include a fourth claw (760) interlocked with the third claw (750).

[0173] For example, the second coil (522a) may be wound around the second inner frame (552b) of the second motor housing (552) within the second region (361b). The third coil (522b) may be wound around the third inner frame (553b) of the third motor housing (553) within the second region (361b). The first set of magnetic members (561) may have different magnetisms depending on the current flowing through the second coil (522a) by being surrounded by the second inner frame (552b) around which the second coil (522a) is wound. The second set of magnetic members (562) may have different magnetisms depending on the current flowing through the third coil (522b) by being surrounded by the third inner frame (553b) around which the third coil (522b) is wound.

[0174] For example, referring to FIGS. 7b, 7c, and 7d, the plurality of magnetic poles (730) of the magnet (531) may each have a designated volume. The plurality of magnetic poles (730) may be arranged to face the magnetic members (561, 562), respectively. For example, the magnet (531) may have a cylindrical shape. The plurality of magnetic poles (730) may be formed such that the areas facing the magnetic members (561, 562) are substantially the same. For example, the first set of magnetic members (561) may be configured to be substantially the same as or similar to the second set of magnetic members (562). The first set of magnetic members (561) may be attached to be misaligned at a designated angle with respect to the second set of magnetic members (562). For example, the magnet (531) may include a through hole (531a) for accommodating the second shaft (502). The through hole (531a) may have, for example, a regular polygonal shape. When the magnetic members (561, 562) are viewed from above, the misaligned angle between the claw (711) of the first claws (710) and the claw (751) of the third claws (750) corresponding to the claw (711) may correspond to half of one interior angle (a) of the regular polygon. The misaligned angle between the claw (721) of the second claws (720) and the claw (761) of the fourth claws (760) corresponding to the claw (721) may correspond to half of one interior angle (a). However, the above-described embodiments are exemplary and are not limited thereto.

[0175] For example, when referring to FIGS. 7b and 7c sequentially, the direction of the current flowing in the second coil (522a) and the third coil (522b) may change while changing from state (701) to state (702). The first coil (710) may change from a N pole to a S pole, and the second coil (720) may change from a S pole to a N pole. The third coil (750) may change from a N pole to a S pole, and the fourth coil (760) may change from a S pole to a N pole. Among the plurality of magnetic poles (730) of the magnet (531), the first magnetic pole (731) and the third magnetic pole (733) having an N pole may provide a rotational force to the magnet (531) by the attraction between them and the magnetic poles (711, 712) having S poles, respectively, to face the magnetic poles (711, 712). Among the above-mentioned plurality of stimuli (730), the second stimuli (732) and the fourth stimuli (734) having an S pole can provide rotational force to the magnet (531) by attraction with the stimuli (721, 722) having an N pole, respectively, to face the stimuli (721, 722).

[0176] For example, when referring to FIGS. 7c and 7d sequentially, the direction of the current flowing in the second coil (522a) and the third coil (522b) may change while changing from state (702) to state (703). For example, the direction of current flowing in the second coil (522a) in state (701) and the direction of current flowing in the second coil (522a) in state (703) may be the same. The direction of current flowing in the third coil (522b) in state (701) and the direction of current flowing in the third coil (522b) in state (703) may be the same. For example, while changing from state (702) to state (703), the first claw (710) may change from a south pole to a north pole, and the second claw (720) may change from a north pole to a south pole. The third claw (750) can be changed from a S pole to a N pole, and the fourth claw (760) can be changed from a N pole to a S pole. Among the plurality of magnetic poles (730) of the magnet (531), the first magnetic pole (731) and the third magnetic pole (733) having an N pole can provide a rotational force to the magnet (531) by facing the magnetic poles (751, 752) having the S poles, respectively, through an attraction with the magnetic poles (751, 752) having the S poles, respectively. Among the plurality of magnetic poles (730), the second magnetic pole (732) and the fourth magnetic pole (734) having an S pole can provide a rotational force to the magnet (531) by facing the magnetic poles (761, 762) having the N poles, respectively, through an attraction with the magnetic poles (761, 762) having the N poles, respectively. However, the above-described embodiments are exemplary and are not limited thereto.

[0177] According to the above-described embodiment, the motor assembly (361) can provide a driving force of the motor assembly (361) by including magnetic members (561, 562) configured to rotate the rotating member (530) based on a change in the direction of current flowing in one or more second coils (522). The first set of magnetic members (561) can be arranged to provide a rotational force of the rotating member (530) by being attached so as to be misaligned at a specified angle with respect to the second set of magnetic members (562).

[0178] FIG. 8A is a partial exploded view of a motor assembly of an exemplary electronic device. FIG. 8B illustrates a portion of a motor assembly of an exemplary electronic device in a fastened state. FIG. 8C is a partial cross-sectional view of the motor assembly of the exemplary electronic device taken along line D-D' of FIG. 8B. FIG. 8D is a partial cross-sectional view of the motor assembly of the exemplary electronic device taken along line E-E' of FIG. 8B. FIG. 8E is a partial cross-sectional view of the motor assembly of the exemplary electronic device taken along line F-F' of FIG. 8B. FIG. 8F is a partial cross-sectional view of the motor assembly of the exemplary electronic device taken along line G-G' of FIG.

[0179] Referring to FIGS. 8A, 8B, 8C, 8D, 8E, and 8F, the electronic device (101) may include a housing (e.g., the housing (200) of FIG. 2A) that includes a first housing (e.g., the first housing (210) of FIG. 2A) and a second housing (e.g., the second housing (220) of FIG. 2A) movably coupled with respect to the first housing (210). The electronic device (101) may include a motor assembly (361) disposed within the housing (200). The electronic device (101) may include a gear assembly (e.g., the gear assembly (510) of FIG. 5A) that is interlocked with the motor assembly (361) to move the second housing (220) with respect to the first housing (210) in accordance with driving of the motor assembly (361). The motor assembly (361) may include a first shaft (501) having a first end (e.g., the first end (501a) of FIG. 6a) coupled to the gear assembly (510) and a second end (501b) opposite the first end (501a). The motor assembly (361) may include a second shaft (502) separated from the first shaft (501). The motor assembly (361) may include a plurality of coils (e.g., the plurality of coils (520) of FIG. 5c) including a first coil (e.g., the first coil (521) of FIG. 5c) disposed along the first shaft (501) and one or more second coils (522) disposed along the second shaft (502). The motor assembly (361) may include a rotating member (530) coupled with the second shaft (502) to rotate the second shaft (502) based on a current flowing in the one or more second coils (522), and including a fastening hole (532a) configured to allow the second end (501b) of the first shaft (501) to be inserted therein.The motor assembly (361) may include a vibrator (540) coupled to the second shaft (502) to provide haptic feedback (600) based on rotation of the second shaft (502). The rotating member (530) may move relative to the first shaft (501) based on current flowing in the first coil (521) to provide a disengaged state and a engaged state. The disengaged state may be a state in which the second end (501b) of the first shaft (501) is separated from the engaging hole (532a) so that the second shaft (502) can rotate relative to the first shaft (501) to provide haptic feedback (e.g., the haptic feedback (600) of FIG. 6A) through the vibrator (540). The above-described fastening state may be a state in which the second end (501b) of the first shaft (501) is inserted into the fastening hole (532a) so that the first shaft (501) can rotate relative to the second shaft (502) to move the second housing (220) relative to the first housing (210). According to one embodiment, the motor assembly (361) may include a stopper (503) that at least partially surrounds the first shaft (501), and an elastic member (504) that presses the stopper (503) toward the rotation member (530).

[0180] According to one embodiment, the rotating member (530) may include a magnet (531) including a plurality of magnetic poles (e.g., a plurality of magnetic poles (730) of FIG. 7a), and a fastening member (532) attached to the magnet (531) toward a second end (501b) and forming a fastening hole (532a). The second end (501b) may have a regular polygonal shape. The number of the plurality of magnetic poles (730) may correspond to twice the number of corners (810) of the second end (501b). The number of recessed portions (820) of the fastening hole (532a) for accommodating the corners (810) of the second end (501b) may correspond to twice the number of the plurality of magnetic poles (730).

[0181] For example, when referring to FIGS. 7b to 7d together with FIGS. 8a and 8e, the fastening hole (532a) may be required to have a shape to accommodate the second end (501b) regardless of the rotation of the rotating member (530) in order to accommodate the second end (501b) while the rotating member (530) rotates within the unfastened state and then changes from the unfastened state to the fastened state. For example, as illustrated, the cross-section of the second end (501b) may have a regular pentagonal shape. The magnet (531) may be configured to include ten magnetic poles so as to rotate by an angle corresponding to half of one interior angle (a) of the regular pentagon within the states (701, 702, 703), as illustrated in FIGS. 7b to 7d. Since the fastening hole (532a) rotates along the magnet (531), the fastening hole (532a) may include 20 recessed portions (820) to accommodate the corners (810) of the second end (501b) having a regular pentagonal shape. However, the above-described embodiment is exemplary and is not limited thereto.

[0182] Referring to FIGS. 8C and 8D , the magnet (531) may include a through hole (531a) for receiving a second shaft (502). The second shaft (502) may include a first portion (502a) configured to be engaged with the through hole (531a) in a disengaged state, and a second portion (502b) extending from the first portion (502a) and guiding movement of the magnet (531) relative to the first shaft (501). For example, the first portion (502a) may have a shape corresponding to the through hole (531a) in order to be engaged with the through hole (531a). For example, the through hole (531a) may surround the second portion (502b). The above through hole (531a) may be slidable or movable with respect to the second part (502b) so that the rotating member (530) can rotate with respect to the second part (502b) in a fastened state with the first shaft (501).

[0183] Referring to FIG. 8F, the stopper (503) can be penetrated by the first shaft (501). The stopper (503) can be slidably coupled to the first shaft (501). The elastic member (504) can at least partially surround the stopper (503). The elastic member (504) can separate the rotational member (530) from the first shaft (501) by pressing the stopper (503) toward the rotational member (530) by a restoring force while changing from a fastened state to a disengaged state.

[0184] According to the above-described embodiment, the rotating member (530) of the motor assembly (361) may include a fastening hole (532a) configured to allow the second end (501b) of the first shaft (501) to be inserted while changing from the fastened state to the fastened state, regardless of the rotation of the rotating member (530) within the fastened state, thereby enabling the electronic device (101) to be changed from the fastened state to the fastened state.

[0185] Figure 9a illustrates a portion of an exemplary electronic device in a first state. Figure 9b illustrates a portion of an exemplary electronic device in a second state.

[0186] Referring to FIGS. 9A and 9B, the electronic device (101) may include a housing (200) including a first housing (210) and a second housing (220) movably coupled with respect to the first housing (210). The electronic device (101) may include a motor assembly (361) disposed within the housing (200). The electronic device (101) may include a gear assembly (e.g., the gear assembly (510) of FIG. 5A) linked with the motor assembly (361) to move the second housing (220) with respect to the first housing (210) in accordance with the driving of the motor assembly (361). The motor assembly (361) may be configured to provide haptic feedback (e.g., haptic feedback (600) of FIG. 6A) or move the second housing (220) relative to the first housing (210) by rotation and / or movement of a rotating member (e.g., rotating member (530) of FIG. 5C) within the motor assembly. The motor assembly (361) and the gear assembly (510) may be referred to as the motor assembly (361) and the gear assembly (510) illustrated in FIGS. 5A to 6B, respectively.

[0187] In one embodiment, the motor assembly (361) may be fastened within the first housing (210) within the housing (200). The pinion gear (362) of the gear assembly (510) may be fastened to the first housing (210) together with the motor assembly (361). The rack gear (363) meshed with the pinion gear (362) may be fastened to the second housing (220). For example, since the second housing (220) moves in a first direction (261) and a second direction (262) opposite to the first direction (261) with respect to the first housing (210), the first housing (210) may be a portion of the housing (200) that is gripped by a user. The motor assembly (361) may be fastened to the first housing (210) that is relatively grippable by the user, thereby providing enhanced haptic feedback (600) to the user, but is not limited thereto. For example, the electronic device (101) may include a display (e.g., the display (230) of FIG. 2A) whose display area changes along the second housing (220) that moves relative to the first housing (210). Depending on the direction of visual objects and / or information displayed through the display (230), the motor assembly (361) may be fastened to a portion of the housing (200) that is easy for the user to grip, thereby providing enhanced haptic feedback (600) to the user.

[0188] According to the above-described embodiment, the motor assembly (361) can provide improved haptic feedback (600) to the user by being fastened to the first housing (210) that is easy for the user to grip.

[0189] Fig. 10 is a block diagram of an exemplary electronic device for driving a motor assembly.

[0190] Referring to FIG. 10, an electronic device (101) may include a housing (e.g., a housing (200) of FIG. 2A) that includes a first housing (e.g., a first housing (210) of FIG. 2A) and a second housing (e.g., a second housing (220) of FIG. 2A) movably coupled with respect to the first housing (210). The electronic device (101) may include a motor assembly (e.g., a motor assembly (361) of FIG. 3B) disposed within the housing (200). The electronic device (101) may include a gear assembly (e.g., a gear assembly (510) of FIG. 5A) that is linked with the motor assembly (361) to move the second housing (220) with respect to the first housing (210) in accordance with driving of the motor assembly (361). The motor assembly (361) may include a first shaft (e.g., the first shaft (501) of FIG. 5c) having a first end coupled to the gear assembly (510) (e.g., the first end (501a) of FIG. 6a) and a second end opposite the first end (501a) (e.g., the second end (501b) of FIG. 5c). The motor assembly (361) may include a second shaft (e.g., the second shaft (502) of FIG. 5c) separated from the first shaft (501). The motor assembly (361) may include a plurality of coils (520) including a first coil (521) disposed along the first shaft (501) and one or more second coils (522) disposed along the second shaft (502). The motor assembly (361) may include a rotating member (530) coupled with the second shaft (502) to rotate the second shaft (502) based on a current flowing in the one or more second coils (522), and including a fastening hole (e.g., fastening hole (532a) of FIG. 5c) configured to allow the second end (501b) of the first shaft (501) to be inserted therein.The motor assembly (361) may include a vibrator (e.g., vibrator (540) of FIG. 5c) coupled to the second shaft (502) to provide haptic feedback (600) based on rotation of the second shaft (502). The rotating member (530) may move relative to the first shaft (501) based on current flowing in the first coil (521) to provide a disengaged state and a engaged state. The disengaged state may be a state in which the second end (501b) of the first shaft (501) is separated from the engaging hole (532a) so that the second shaft (502) can rotate relative to the first shaft (501) to provide haptic feedback (e.g., haptic feedback (600) of FIG. 6a) through the vibrator (540). The above-described fastening state may be a state in which the second end (501b) of the first shaft (501) is inserted into the fastening hole (532a) so that the first shaft (501) can rotate relative to the second shaft (502) to move the second housing (220) relative to the first housing (210).

[0191] According to one embodiment, the electronic device (101) may include a power management circuit (1010), a converter (1020), and a motor assembly drive circuit (1030). The converter (1020) may be configured to change a voltage required for the motor assembly (361) based on power provided from a battery (e.g., battery (189) of FIG. 1) by the power management circuit (1010). The motor assembly drive circuit (1030) may control the motor assembly (361) to drive the motor assembly (361) based on the power supplied by the power management circuit (1010).

[0192] According to one embodiment, the processor (120) may control the power management circuit (1010) to cause current to flow through one or more second coils (522) of the plurality of coils (520) based on receiving a first user input for haptic feedback (600). For example, the processor (120) may control the power management circuit (1010) and / or the motor assembly drive circuit (1030) to cause current to flow through the second coil (522a) and the third coil (522b) based on the first user input for haptic feedback (600). Since no current flows through the first coil (521), the electronic device (101) may remain in an unlatched state. The processor (120) can rotate a rotating member (530) including a magnet (e.g., a magnet (531) of FIG. 5C) within a motor assembly (361) by controlling the power management circuit (1010) and / or the motor assembly driving circuit (1030) to periodically change the direction of the current flowing in the second coil (522a) and the third coil (522b). The motor assembly (361) can provide the haptic feedback (600) through a second shaft (502) coupled with the rotating member (530) so as to rotate together with the rotating member (530), and a vibrator (540).

[0193] In one embodiment, the processor (120) may control the power management circuit (1010) to energize the first coil (521) based on receiving a second user input for movement of the second housing (220) relative to the first housing (210). The processor (120) may control the power management circuit (1010) to energize the one or more second coils (522) while the current flows through the first coil (521). For example, the processor (120) may control the power management circuit (1010) and / or the motor assembly drive circuit (1030) to energize the first coil (521) based on the second user input for movement of the second housing (220) relative to the first housing (210). Since the fastening hole (532a) of the rotating member (530) is fastened to the second end (501b) of the first shaft (501) while current flows through the first coil (521), the electronic device (101) can maintain the fastened state. The processor (120) can control the power management circuit (1010) and / or the motor assembly driving circuit (1030) so that current flows through the second coil (522a) and the third coil (522b) while current flows through the first coil (521). The processor (120) can rotate the rotating member (530) including the magnet (531) in the motor assembly (361) by controlling the power management circuit (1010) and / or the motor assembly driving circuit (1030) to periodically change the direction of the current flowing in the second coil (522a) and the third coil (522b). The motor assembly (361) can move the second housing (220) relative to the first housing (210) through the first shaft (501) and the gear assembly (510) fastened to the fastening hole (532a) so as to rotate together with the rotating member (530) within the fastening state.

[0194] According to the above-described embodiment, the processor (120) can provide various user experiences to the user by controlling the power management circuit (1010) (and / or the motor assembly drive circuit (1030)) to provide haptic feedback (600) using the motor assembly (361) through a plurality of coils (520) or to move the second housing (220) relative to the first housing (210).

[0195] Figures 11a and 11b are flowcharts of exemplary electronic devices for driving a motor assembly.

[0196] The operations of FIG. 11a and FIG. 11b can be performed by the processor (120) of the electronic device (101) of FIG. 1 and FIG. 10.

[0197] Referring to FIGS. 11A and 11B , in operation (1101), the processor (120) may receive a first user input for haptic feedback (e.g., haptic feedback (600) of FIG. 6A ). For example, the processor (120) may determine a haptic pattern corresponding to the first user input from among set haptic patterns (e.g., haptic patterns (601, 602, 603, 604) of FIG. 6A ) based on the first user input.

[0198] In operation (1103), the processor (120) may identify whether the second housing (e.g., the second housing (220) of FIG. 2A) is moving relative to the first housing (e.g., the first housing (210) of FIG. 2A). For example, the processor (120) may identify whether current is flowing through both the first coil (e.g., the first coil (521) of FIG. 5C) and one or more second coils (522) based on receiving a first user input for haptic feedback (600). If the processor (120) does not identify the second housing (220) as moving relative to the first housing (210) (e.g., 1103-No), the processor (120) may perform operation (1107).

[0199] Referring to FIG. 11A, in operation (1105), the processor (120) may control a power management circuit (e.g., the power management circuit (1010) of FIG. 10) to bypass and / or block current flow to a plurality of coils (e.g., the plurality of coils (520) of FIG. 5C) based on identifying that the second housing (220) is moving relative to the first housing (210). For example, the processor (120) may control the power management circuit (1010) to bypass and / or block current flow to the plurality of coils (520) based on identifying that current flow to the plurality of coils (520). Since current does not flow to the first coil (521), the electronic device (101) may change from a engaged state to an unengaged state. Since no current flows through one or more of the second coils (522), the rotation of the rotating member (e.g., the rotating member (530) of FIG. 5c) is stopped, thereby stopping the movement of the second housing (220) relative to the first housing (210).

[0200] In operation (1107), the processor (120) may control the power management circuit (1010) to cause current to flow through one or more second coils for a haptic pattern according to the first user input. For example, in operation (1107), the processor (120) may control the power management circuit (1010) to periodically change the direction of the current flowing through one or more second coils (522) within the disengaged state, thereby providing a haptic pattern according to the first user input.

[0201] In operation (1109), the processor (120) may control the power management circuit (1010) to bypass and / or block the flow of current to one or more second coils (522) based on a haptic pattern according to a first user input provided during a designated time period. By bypassing and / or blocking the flow of current to the one or more second coils (522), the electronic device (101) may stop providing the haptic pattern.

[0202] Referring to FIG. 11B, in operation (1111), the processor (120) may control the display (e.g., the display (230) of FIG. 2A) to display a screen related to the first user input, unlike in operation (1105) of FIG. 11A. For example, the processor (120) may control the display (230) to display a screen related to the first user input and / or a haptic pattern according to the first user input while current flows through the plurality of coils (520).

[0203] Figure 12 is a flow diagram of an exemplary electronic device for driving a motor assembly.

[0204] The operations of FIG. 12 can be performed by the processor (120) of the electronic device (101) of FIG. 1 and FIG. 10.

[0205] Referring to FIG. 12, in operation (1201), the processor (120) may receive a second user input for moving a second housing (e.g., the second housing (220) of FIG. 2A) relative to a first housing (e.g., the first housing (210) of FIG. 2A). For example, the processor (120) may receive a second user input for changing the size of a display area of ​​a display (e.g., the display (230) of FIG. 2A) that is visually exposed to the outside of the electronic device (101).

[0206] In operation (1203), the processor (120) may control the power management circuit (e.g., the power management circuit (1010) of FIG. 10) to cause current to flow in the first coil (e.g., the first coil (521) of FIG. 5C) based on the second user input. By causing current to flow in the first coil (521), the rotating member (e.g., the rotating member (530) of FIG. 5C) in the motor assembly (e.g., the motor assembly (361) of FIG. 3B) may move toward the first shaft (e.g., the first shaft (501) of FIG. 5C). The electronic device (101) may change from a disengaged state to a engaged state by causing the first shaft (501) to be engaged in the engaging hole (e.g., the engaging hole (532a) of FIG. 5C) of the rotating member (530).

[0207] In operation (1205), the processor (120) may control the power management circuit (1010) to cause current to flow through one or more second coils (522) to move the second housing (220) relative to the first housing (210) while current flows through the first coil (521). For example, while the engagement state is maintained through the current flowing through the first coil (521), the processor (120) may control the power management circuit (1010) to periodically change the direction of the current flowing through the one or more second coils (522). The rotating member (530) (or the magnet (531) included in the rotating member (530)) may be rotated by the current flowing through the one or more second coils (522). The first shaft (501) connected to the connection hole (532a) of the above-described rotating member (530) can move the second housing (220) relative to the first housing (210) through a gear assembly (e.g., the gear assembly (510) of FIG. 5a) by rotating together with the above-described rotating member (530).

[0208] In operation (1207), the processor (120) may be configured to identify whether the second housing (220) is moving relative to the first housing (210). The processor (120) may control the power management circuit (1010) to cause current to flow through the plurality of coils (520) while identifying that the second housing (220) is moving relative to the first housing (210) (e.g., 1207-Yes).

[0209] In operation (1209), the processor (120) may control the power management circuit (1010) to bypass and / or block the flow of current to one or more second coils (522) based on identifying that movement of the second housing (220) relative to the first housing (210) has stopped. For example, the processor (120) may control the power management circuit (1010) to bypass and / or block the flow of current to one or more second coils (522) based on identifying a display area of ​​an externally exposed display of the electronic device (101) (e.g., display (230) of FIG. 2A) set based on a second user input. For example, the processor (120) may control the power management circuit (1010) to bypass and / or block current flow to one or more second coils (522) based on identifying the display (230) in a first state in which the size of the display area of ​​the display (230) visually exposed to the outside of the electronic device (101) is minimized or in a second state in which the size of the display area is maximized.

[0210] According to the above-described embodiment, an electronic device (e.g., electronic device (101) of FIG. 1) may include a housing (e.g., housing (200) of FIG. 2A) including a first housing part (e.g., first housing (210) of FIG. 2A) and a second housing part (e.g., second housing (220) of FIG. 2A) movably coupled with respect to the first housing part. The electronic device may include a motor assembly disposed within the housing, the motor assembly including a first shaft (e.g., first shaft (501) of FIG. 5C), a second shaft separate from the first shaft (e.g., second shaft (502) of FIG. 5A), a rotating member configured to be coupled to at least one of the first shaft and the second shaft (e.g., rotating member (530) of FIG. 5C), and a vibrator coupled to one side of the second shaft (e.g., vibrator (540) of FIG. 5A). The electronic device may include a gear assembly (e.g., gear assembly (510) of FIG. 5A) that is coupled to the first shaft to move the second housing part relative to the first housing part in response to driving of the motor assembly. The electronic device may include at least one processor (e.g., processor (120) of FIG. 1) and a memory (e.g., memory (130) of FIG. 1) that includes one or more storage media storing instructions. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the rotating member to be coupled to the first shaft such that the second housing part is movable relative to the first housing part via the rotating member. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the rotating member to be coupled to the second shaft such that the vibrator provides vibration via the rotating member.

[0211] For example, the motor assembly may further include a plurality of coils surrounding the rotating member, the coils including a first coil (e.g., a first coil (521) of FIG. 5C) disposed along the first shaft and one or more second coils (e.g., one or more second coils (522) of FIG. 5C) disposed along the second shaft. The rotating member may further include a magnet (e.g., a magnet (531) of FIG. 5C) including a through hole that accommodates at least a portion of the second shaft, and a fastening member (e.g., a fastening member (532) of FIG. 5C) that is attached to the magnet and faces the first shaft and forms a fastening hole (e.g., a fastening hole (532a) of FIG. 5C) configured to be fastened to the first shaft. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to move the rotating member toward the first shaft such that the engaging hole is engaged with the first shaft through a magnetic force with the engaging member based on a current flowing through the first coil. The instructions may cause the rotating member to rotate through a magnetic field formed by the magnet based on a current flowing through the one or more second coils.

[0212] For example, the magnet may include a plurality of poles (e.g., a plurality of poles (730) of FIG. 7a). The one or more second coils may include a second coil (e.g., a second coil (522a) of FIG. 5c) and a third coil (e.g., a third coil (522b) of FIG. 5c) arranged along the magnet. The motor assembly may further include a first set of magnetic elements (e.g., a first set of magnetic elements (561) of FIG. 5c) disposed between the magnet and the second coil and having different poles based on a current flowing through the second coil. The motor assembly may further include a second set of magnetic elements (e.g., the second set of magnetic elements (562) of FIG. 5c) arranged between the magnet and the third coil and configured to rotate the rotating element through magnetic force with the plurality of magnetic elements together with the first set of magnetic elements by having different magnetic poles based on a current flowing through the third coil.

[0213] For example, the second shaft may include a first portion (e.g., the first portion (502a) of FIG. 5C) configured to be coupled to the rotating member, and a second portion (e.g., the second portion (502b) of FIG. 5C) connected to the first portion and configured to guide movement of the rotating member. The rotating member may be configured to provide haptic feedback (e.g., the haptic feedback (600) of FIG. 6A) via the vibrator by being coupled to the first portion. The rotating member may be configured to be coupled to the first shaft by being separated from the first portion along the second portion.

[0214] For example, the motor assembly may further include a plurality of coils surrounding the rotating member, the coils including a first coil disposed along the first shaft and one or more second coils disposed along the second shaft. The motor assembly may further include a stopper (e.g., a stopper (503) of FIG. 5C) slidably coupled to the first shaft and in contact with the rotating member, and an elastic member (e.g., an elastic member (504) of FIG. 5C) that urges the stopper toward the rotating member. The rotating member may be configured to move in a first direction (e.g., a third direction (263) of FIG. 6A) by urging the stopper based on a current flowing in the first coil. The rotating member may be configured to move in a second direction (e.g., a fourth direction (264) of FIG. 6A) opposite to the first direction by the elastic member based on the first coil to which the current flow is bypassed.

[0215] For example, the gear assembly may include a third shaft (e.g., the third shaft (512) of FIG. 5A) configured to rotate based on the rotation of the first shaft, and a reducer (e.g., the reducer (511) of FIG. 5A) connected to the third shaft and meshed with the first shaft. The rotational speed of the third shaft in a state in which the rotating member is fastened to the first shaft may be lower than the rotational speed of the first shaft in a state in which the rotating member is fastened to the first shaft.

[0216] For example, the gear assembly may further include a pinion gear (e.g., pinion gear (362) of FIG. 3B) coupled with the third shaft so as to be rotated by the third shaft. The gear assembly may further include a rack gear (e.g., rack gear (363) of FIG. 3B) disposed within the housing along a direction of movement of the second housing part relative to the first housing part so as to mesh with the pinion gear and move the second housing part relative to the first housing part in accordance with rotation of the pinion gear.

[0217] For example, the electronic device may include a power management circuit (e.g., the power management circuit 1010 of FIG. 10). The motor assembly may include a plurality of coils surrounding the rotating member, the plurality of coils including a first coil disposed along the first shaft and one or more second coils disposed along the second shaft. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the power management circuit to cause current to flow through the one or more second coils of the plurality of coils based on receiving a first user input for haptic feedback. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the power management circuit to cause current to flow through the first coil based on receiving a second user input for movement of the second housing part relative to the first housing part, and to control the power management circuit to cause current to flow through the one or more second coils while current is flowing through the first coil.

[0218] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to identify, based on the first user input, whether the second housing part is moving relative to the first housing part. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the power management circuitry to bypass current flow through the plurality of coils based on identifying the second housing part as moving relative to the first housing part. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the power management circuitry to bypass current flow through the one or more second coils based on identifying the first coil through which current flow is bypassed.

[0219] For example, the electronic device may further include a display (e.g., display (230) of FIG. 2A). The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to identify, based on the first user input, whether the second housing part is moving relative to the first housing part. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the display to display, through the display, a screen related to the first user input, based on identifying the second housing part as moving relative to the first housing part.

[0220] For example, the motor assembly may further include a plurality of coils surrounding the rotating member, the coils including a first coil disposed along the first shaft and one or more second coils disposed along the second shaft. The motor assembly may further include a first region (e.g., the first region 361a of FIG. 6A) in which the first coil is disposed, and a second region (e.g., the second region 361b of FIG. 6A) in which the one or more second coils are disposed. The rotating member may be positioned within the second region while in a state engaged with the second shaft. The rotating member may be partially positioned within the first region by sliding within the motor assembly while changing from a state engaged with the second shaft to a state engaged with the first shaft.

[0221] For example, the rotating member may be slidably coupled to the second shaft within the motor assembly.

[0222] For example, the vibrator may include a mass that is eccentric with respect to the second shaft.

[0223] For example, the first shaft and the second shaft may be concentric with each other.

[0224] For example, the electronic device may further include a display including a first display area disposed on the second housing part, and a second display area (e.g., the second display area (232) of FIG. 2c) extending from the first display area (e.g., the first display area (231) of FIG. 2c) and at least partially retracted within the first housing part or visually exposed to the outside of the electronic device according to movement of the second housing part relative to the first housing part.

[0225] In one embodiment, an electronic device (e.g., electronic device (101) of FIG. 1) may include a housing (e.g., housing (200) of FIG. 2A) including a first housing part (e.g., first housing (210) of FIG. 2A) and a second housing part (e.g., second housing (220) of FIG. 2A) movably coupled with respect to the first housing part. The electronic device may include a motor assembly (e.g., motor assembly (361) of FIG. 3B) disposed within the housing, and a gear assembly (e.g., gear assembly (510) of FIG. 5A) coupled with the motor assembly to move the second housing part with respect to the first housing part in response to driving of the motor assembly. The motor assembly may include a first shaft (e.g., the first shaft (501) of FIG. 5c) having a first end coupled with the gear assembly (e.g., the first end (501a) of FIG. 6a) and a second end opposite the first end (e.g., the second end (501b) of FIG. 5c), and a second shaft (e.g., the second shaft (502) of FIG. 5a) separated from the first shaft. The motor assembly may include a plurality of coils (e.g., the plurality of coils (520) of FIG. 5c) including a first coil (e.g., the first coil (521) of FIG. 5c) disposed along the first shaft and one or more second coils (e.g., one or more second coils (522) of FIG. 5c) disposed along the second shaft. The motor assembly may include a rotating member (e.g., rotating member (530) of FIG. 5c) coupled to the second shaft to rotate the second shaft based on a current flowing through the one or more second coils and including a fastening hole (e.g., fastening hole (532a) of FIG. 5c) configured to be inserted into the second end of the first shaft. The motor assembly may include a vibrator (e.g., vibrator (540) of FIG. 5a) coupled to the second shaft to rotate together with the second shaft based on rotation of the second shaft.The rotating member may provide a disengaged state in which the second end of the first shaft is separated from the engaging hole so that the second shaft can rotate with respect to the first shaft, based on the current flowing in the first coil, to rotate the vibrator. The rotating member may provide a engaged state in which the second end of the first shaft is inserted into the engaging hole so that the first shaft can rotate with respect to the second shaft, to move the second housing part with respect to the first housing part, based on the current flowing in the first coil.

[0226] For example, the rotating member may further include a magnet (e.g., magnet (531) of FIG. 5C) including a through hole that accommodates at least a portion of the second shaft, and a fastening member (e.g., fastening member (532) of FIG. 5C) attached to the magnet toward the second end of the first shaft and forming the fastening hole. The first coil may be configured to move the rotating member through a magnetic force with the fastening member based on a current flowing through the first coil. The one or more second coils may be configured to rotate the rotating member through a magnetic field formed by the magnet based on a current flowing through the one or more second coils.

[0227] For example, the magnet may include a plurality of poles (e.g., a plurality of poles (730) of FIG. 7a). The one or more second coils may include a second coil (e.g., a second coil (522a) of FIG. 5c) and a third coil (e.g., a third coil (522b) of FIG. 5c) arranged along the magnet. The motor assembly may further include a first set of magnetic elements (e.g., a first set of magnetic elements (561) of FIG. 5c) disposed between the magnet and the second coil and having different poles based on a current flowing through the second coil. The motor assembly may further include a second set of magnetic elements (e.g., the second set of magnetic elements (562) of FIG. 5c) arranged between the magnet and the third coil and configured to rotate the rotating element through magnetic force with the plurality of magnetic elements together with the first set of magnetic elements by having different magnetic poles based on a current flowing through the third coil.

[0228] For example, the second shaft (502) may include a first portion (e.g., the first portion (502a) of FIG. 5C) configured to be engaged with the rotating member, and a second portion (e.g., the second portion (502b) of FIG. 5C) connected to the first portion and configured to guide movement of the rotating member (530). The rotating member may be configured to provide haptic feedback (e.g., the haptic feedback (600) of FIG. 6A) via the vibrator by being engaged with the first portion in the disengaged state. The rotating member may be configured to be engaged with the second end of the first shaft by being separated from the first portion in the engaged state.

[0229] For example, the second end of the first shaft may have a regular polygonal shape. The number of the plurality of magnetic poles may correspond to twice the number of corners of the second end. The number of recessed portions of the fastening hole for accommodating the corners of the second end may correspond to twice the number of the plurality of magnetic poles.

[0230] For example, the motor assembly may further include a stopper (e.g., a stopper (503) of FIG. 5C) coupled to the first shaft and in contact with the rotating member, and an elastic member (e.g., an elastic member (504) of FIG. 5C) that presses the stopper. The rotating member may be configured to move in a first direction (e.g., a third direction (263) of FIG. 6A) by pressing the stopper based on a current flowing in the first coil while changing from the disengaged state to the engaged state. The rotating member may be configured to move in a second direction (e.g., a fourth direction (264) of FIG. 6A) opposite to the first direction by the elastic member based on the first coil to which the current flow is bypassed while changing from the engaged state to the disengaged state.

[0231] For example, the gear assembly may include a third shaft (e.g., the third shaft (512) of FIG. 5A) configured to rotate based on the rotation of the first shaft, and a reducer (e.g., the reducer (511) of FIG. 5A) connected to the third shaft (512) and meshed with the first end of the first shaft. A rotational speed of the third shaft in the engaged state may be less than a rotational speed of the first shaft in the engaged state.

[0232] For example, the gear assembly may further include a pinion gear (e.g., pinion gear (362) of FIG. 3B) coupled with the third shaft so as to be rotated by the third shaft, and a rack gear (e.g., rack gear (363) of FIG. 3B) meshing with the pinion gear and positioned along a direction of movement of the second housing part relative to the first housing part within the housing so as to move the second housing relative to the first housing part in accordance with rotation of the pinion gear.

[0233] For example, the electronic device may include a power management circuit (e.g., the power management circuit 1010 of FIG. 10), at least one processor including a processing circuit (e.g., the processor 120 of FIG. 1), and a memory including one or more storage media storing instructions (e.g., the memory 130 of FIG. 1). The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the power management circuit to cause current to flow through the first coil and the one or more second coils of the one or more second coils based on receiving a first user input for the haptic feedback. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the power management circuit to cause current to flow through the first coil based on receiving a second user input for movement of the second housing part relative to the first housing part. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the power management circuit to cause current to flow through the one or more second coils while current flows through the first coil based on receiving a second user input for movement of the second housing part relative to the first housing part.

[0234] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to identify, based on the first user input, whether the second housing is moving relative to the first housing part. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the power management circuitry to bypass current flow through the plurality of coils based on identifying the second housing part as moving relative to the first housing part. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the power management circuitry to bypass current flow through the one or more second coils based on identifying the first coil through which current flow is bypassed.

[0235] For example, the electronic device may further include a display (e.g., display (230) of FIG. 2A). The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to identify, based on the first user input, whether the second housing part is moving relative to the first housing part. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the display to display, through the display, a screen related to the first user input, based on identifying the second housing part as moving relative to the first housing part.

[0236] For example, the motor assembly may further include a first region (e.g., the first region (361a) of FIG. 6A) in which the first coil is disposed, and a second region (e.g., the second region (361b) of FIG. 6A) in which the one or more second coils are disposed. The rotating member may be positioned within the second region within the disengaged state. The rotating member may be partially positioned within the first region by sliding within the motor assembly while changing from the disengaged state to the engaged state.

[0237] For example, the rotating member may be slidably coupled to the second shaft within the motor assembly.

[0238] For example, the vibrator may include a mass that is eccentric with respect to the second shaft.

[0239] For example, the first shaft and the second shaft may be concentric with each other.

[0240] For example, the electronic device may further include a display including a first display area (e.g., the first display area (231) of FIG. 2C) disposed on the second housing part, and a second display area (e.g., the second display area (232) of FIG. 2C) extending from the first display area and at least partially retracting within the first housing part or visually exposed to the outside of the electronic device depending on movement of the second housing part relative to the first housing part.

[0241] In one embodiment, an electronic device may include a housing comprising a first housing part and a second housing part movably coupled with respect to the first housing part. The electronic device may include a motor assembly disposed within the housing, and a gear assembly including a reducer and coupled with the motor assembly to move the second housing part with respect to the first housing part in response to driving of the motor assembly. The motor assembly may include a first shaft including a first end coupled with the reducer and a second end opposite the first end, and a second shaft separated from the first shaft. The motor assembly may include a rotating member including a magnet including a through hole for receiving the second shaft to rotate the second shaft based on power supplied to the motor assembly, and a fastening member attached to the magnet and including a fastening hole configured to be inserted into the second end of the first shaft. The motor assembly may include a vibrator coupled to the second shaft and eccentric with respect to the second shaft to provide haptic feedback based on rotation of the second shaft. The rotating member may provide a disengaged state in which the second end of the first shaft is separated from the engaging hole so that the second shaft is rotatable with respect to the first shaft to provide the haptic feedback via the vibrator by moving with respect to the first shaft. The rotating member may provide a engaged state in which the second end of the first shaft is inserted into the engaging hole so that the first shaft is rotatable with respect to the second shaft to move the second housing part with respect to the first housing part.

[0242] For example, the motor assembly may include a plurality of coils, including a first coil disposed along the first shaft, and one or more second coils at least partially surrounding the rotatable member. The first coil may be configured to move the rotatable member through a magnetic force with the fastening member based on a current flowing through the first coil. The one or more second coils may be configured to rotate the rotatable member through a magnetic field formed by the magnet based on a current flowing through the one or more second coils.
