[0032] Referring to FIG. 1, in a network environment (100), an electronic device (101) may communicate with an electronic device (102) through 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) through a second network (199) (e.g., a long-range wireless communication network).

[0033] In one embodiment, the electronic device (101) may communicate with the electronic device (104) via the server (108).

[0035] In one embodiment, some of these components (e.g., a sensor module (176), a camera module (180), or an antenna module (197)) may be integrated into one component (e.g., a display module (160)). The processor (120) may, for example, execute software (e.g., a program (140)) to control at least one other component (e.g., a hardware or software component) of the electronic device (101) connected to the processor (120) and perform various data processing or operations.

[0036] In one embodiment, as at least part of data processing or calculation, the processor (120) may store commands or data received from another component (e.g., a sensor module (176) or a communication module (190)) in the volatile memory (132), process the commands or data stored in the volatile memory (132), and store resulting data in the non-volatile memory (134).

[0037] For example, if the electronic device (101) includes a main processor (121) and a secondary processor (123), the secondary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a specified function. The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0038] 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)).

[0039] In one embodiment, the auxiliary processor (123) (e.g., a neural network processing device) may include a hardware structure specialized for processing an artificial intelligence model.

The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In 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.

[0045] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. In 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).

[0046] 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.

[0051] The power management module (188) can manage power supplied to the electronic device (101). In one embodiment, the power management module (188) can be implemented, for example, as at least a part of a power management integrated circuit (PMIC).

[0052] 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.

[0053] 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. In 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).

[0054] 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)). In one embodiment, the wireless communication module (192) may support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL) each, or 1 ms or less for round trip) for URLLC realization.

In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the selected at least one antenna. In one embodiment, 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).

[0056] In one embodiment, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC positioned 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) positioned on or adjacent a second side (e.g., a top side or a side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0057] At least some of the 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, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

[0058] In 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). In 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 additional functions or services 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. In 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.

[0059] It should be understood that the various embodiments and terminology used herein are not intended to limit the technical features described in the present disclosure to specific embodiments, but rather to encompass various modifications, equivalents, or substitutes of the embodiments. In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more items, unless the context clearly indicates otherwise. In the present disclosure, each of the phrases "A or B," "at least one of A and B," "at least one of A or B," "A, B, or C," "at least one of A, B, and C," and "at least one of A, B, or C" can include any one of the items listed together in the corresponding phrase among the phrases, or all possible combinations thereof. Terms such as "first", "second", or "first" or "second" may be used merely to distinguish one component from another, and do not limit the components in any other respect (e.g., importance or order). When a component (e.g., a first) is referred to as "coupled" or "connected" to another (e.g., a second) component, with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0060] The term "module" as used in various embodiments may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component or a minimum unit or part of a component that performs one or more functions. For example, in one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

For example, a processor of the machine (e.g., an electronic device) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one instruction called. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' only means that the storage medium is a tangible device and does not contain a signal (e.g., an electromagnetic wave), and this term does not distinguish between cases where data is stored semi-permanently and cases where it is stored temporarily in the storage medium.

[0062] In one embodiment, the method according to the various embodiments disclosed in the present disclosure may be provided as included in a computer program product.

The band fixing ring (255) may limit the range of motion of the fastening members (250, 260) when the fastening member (252) and the fastening member fastening hole (253) are fastened.

[0079] Referring to FIGS. 3A and 3B, an electronic device (300) according to one embodiment may be a wearable device that can be attached to a part of the body.

[0080] An electronic device (300) according to an embodiment (e.g., electronic device (101) of FIG. 1 or electronic device (200) of FIG. 2A) may include at least a portion of a housing (310) (e.g., housing (210) of FIG. 2A), a wheel key (320) (e.g., wheel key (202) of FIG. 2A), a display (330), a support member (340) (e.g., a bracket), a battery (350), a printed circuit board (360), a sealing member (370), a fastening member (381, 382) (e.g., fastening member (250, 260) of FIG. 2A), and / or an antenna module (390, 395) (e.g., antenna module (197) of FIG. 1).

However, this is merely exemplary, and the configurations placed inside the housing (310) are not limited thereto, and some or all of the above-described configurations may be placed outside the housing (310).

[0083] In one embodiment, the wheel key (320) may be positioned on an external front surface (e.g., a +z-direction surface) of the housing (310). The wheel key (320) may be rotatable in at least one direction.

[0084] In one embodiment, the display (330) can visually display information. The display (330) can be positioned toward the front side (e.g., the +z-direction side) of the electronic device (300) so as to be visually exposed through at least a portion of the front plate (311).

[0085] In one embodiment, the support member (340) may be disposed inside the electronic device (300) and connected to the side bezel structure (313) or may be formed integrally with the side bezel structure (313). The support member (340) may be formed of, for example, a metallic material and / or a non-metallic (e.g., a polymer) material. Various configurations may be disposed and supported on the support member (340). For example, a display (330) may be disposed and supported on one surface (e.g., a surface in the +z direction) of the support member (340).

[0086] In one embodiment, the battery (350) may power at least one component of the electronic device (300). For example, the battery (350) may include a primary battery, a secondary battery, or a fuel cell. The battery (350) may be integrally disposed within the electronic device (300) or may be detachably disposed on the electronic device (300). For example, the battery (350) may be positioned toward the rear of the support member (340) (e.g., in the -z direction). However, this is merely exemplary, and the position of the battery (350) is not limited thereto. For example, at least a portion of the battery (350) may be disposed substantially on the same plane as the printed circuit board (360).

[0087] In one embodiment, the printed circuit board (360) may be equipped with a processor, memory, and / or an interface. The processor may include, for example, one or more of a central processing unit (CPU), an application processor, a graphic processing unit (GPU), an application processor, a sensor processor, or a communication processor. The memory may include, for example, volatile memory or non-volatile memory. The interface may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, and / or an audio interface. The interface may electrically or physically connect the electronic device (300) to an external electronic device, and may include, for example, a USB connector, an SD card / MMC connector, or an audio connector. The printed circuit board (360) may be positioned in a rearward direction (e.g., in the -z direction) of the display (330) and / or the battery (350).

[0088] In one embodiment, the sealing member (370) may be positioned between the side bezel structure (313) and the rear plate (312). The sealing member (370) may be configured to block moisture and foreign substances from entering the space surrounded by the side bezel structure (313) and the rear plate (312) from the outside.

[0089] In one embodiment, the antenna module (390, 395) may include at least one of a first antenna (390) and a second antenna (395). The antenna module (390, 395) may be positioned closer to the rear side (e.g., the -z direction side) than the front side (e.g., the +z direction side) of the electronic device (300). For example, the first antenna (390) may be positioned between the display (330) and the support member (340), and the second antenna (395) may be positioned between the printed circuit board (360) and the rear plate (312). However, FIGS. 3A and 3B are merely exemplary drawings, and the antenna module (390, 395) of one embodiment may be formed as a single continuous structure or a plurality of connected structures. Alternatively, in one embodiment, the antenna module (390, 395) may be formed by a portion or combination of the side bezel structure (313) and / or the support member (340).

[0090] In one embodiment, the antenna module (390, 395) may include, for example, a near field communication (NFC) antenna, a wireless charging antenna, and / or a magnetic secure transmission (MST) antenna.

[0092] Specifically, FIG. 4b is a plan view and an enlarged view of a portion of an electronic device (400) omitting some components of the electronic device (400) (e.g., the second coupling member (426) of the rotation unit (420)), FIG. 4c is a cross-sectional view of the electronic device (400) viewed in the A-A' direction of FIG. 4b, and FIGS. 4d and 4e are cross-sectional views of the electronic device (400) viewed in the B-B' direction of FIG. 4b.

[0093] Referring to FIGS. 4a, 4b, 4c, 4d, 4e, 4f, and 4g, an electronic device (400) according to an embodiment (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2a and 2b, or the electronic device (300) of FIGS. 3a and 3b) may include at least a portion of a housing structure (410) (e.g., the housing (210) of FIGS. 2a and 2b or the housing (310) of FIGS. 3a and 3b), a rotation unit (420) (e.g., the wheel key (320) of FIG. 3a), and a locking unit (440).

[0094] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that some components and structures of the electronic device (400) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the electronic device (400) unless it is technically clearly impossible.

[0095] In one embodiment, the electronic device (400) may be a wearable device that can be attached to a part of the body, such as a smartwatch. Alternatively, and not limited thereto, the electronic device (400) may be any one of various types of devices, such as a wireless communication device, a display device, a home appliance, an industrial device, or a computer processing device.

[0096] In one embodiment, the housing structure (410) may form the exterior of the electronic device (400). Alternatively, the housing structure (410) may accommodate, support, and / or protect electrical components of the electronic device (400). Alternatively, the housing structure (410) may be the body or main body of the electronic device (400).

[0097] In one embodiment, the housing structure (410) may include a first side (411), a second side (412), and a third side (413). The first side (411) may be a side or a front side facing one direction (e.g., a +Z direction). A bonding area (415) may be provided on the first side (411). The second side (412) may be a side or a back side facing a direction opposite to the first side (411) (e.g., a -Z direction). The third side (413) may be a side extending from the first side (411) to the second side (412), for example, a side surface.

[0098] In one embodiment, the housing structure (410) may include a coupling area (415). The coupling area (415) may be an area to which the rotation unit (420) is coupled. The shape, structure, and size of the coupling area (415) are not limited, and may have a shape surrounding an opening in the center of the housing structure (410), as illustrated in FIG. 4A.

[0099] In one embodiment, the bonding region (415) may have a shape corresponding to the shape of the rotation unit (420).

[0100] For example, the rotating unit (420) may have various rotatable shapes. For example, the rotating unit (420) may be wheel-shaped, annular, or ring-shaped. Additionally, the coupling region (415) may be wheel-shaped, annular, or ring-shaped.

[0101] However, the shape of the coupling region (415) and / or the rotation unit (420) according to one embodiment of the present document is not limited thereto and may be implemented in various forms. In addition, the first coupling member (421) and the second coupling member (426) constituting the rotation unit (420) are not limited to a wheel shape or a constant shape and may have various shapes. In addition, the shapes of the first coupling member (421) and the second coupling member (426) of the rotation unit (420) according to one embodiment may be formed in different shapes. For example, a part of the second wheel member (426) may be formed in a polygonal shape (e.g., a square) rather than a wheel shape.

[0102] In one embodiment, the rotation unit (420) may be rotatably fastened to the coupling area (415). The rotation unit (420) may be rotated clockwise and / or counterclockwise with respect to a state facing the front of the electronic device (400) (e.g., the state of FIG. 4b).

[0103] In one embodiment, an input module of an electronic device (400) (e.g., input module (150) of FIG. 1) can detect a rotational state of a rotational unit (420). Alternatively, the rotational unit (420) may be a part of the input module (150). The input module (150) can acquire information about a rotational state of the rotational unit (420) (e.g., rotational direction, rotational angle, rotational degree, and / or rotational speed).

[0104] In one embodiment, at least one processor (e.g., processor (120) of FIG. 1) of the electronic device (400) may receive a detection result from the input module (150). The processor (120) may control the operation of the electronic device (400) based on the rotational state of the rotation unit (420).

[0105] In one embodiment of the present document, the electronic device (400) can receive input information for driving the electronic device (400) through the rotation unit (420). The user can easily, simply, and intuitively control the driving of the electronic device (400) by rotating the rotation unit (420). In addition, the electronic device (400) can omit an additional input switch or input key by including the rotation unit (420), and the rotation unit (420) can provide manufacturing efficiency and space efficiency of the electronic device (400).

[0106] In one embodiment, a guide member (409) may be provided between the housing structure (410) and the rotation unit (420). The guide member (409) may support the rotation unit (420) so that it is rotatably fastened to the housing structure (410). Alternatively, the guide member (409) may support the rotation unit (420) so that the rotation unit (420) does not come off during rotational driving, or may guide the rotation of the rotation unit (420).

[0107] In one embodiment, the rotation unit (420) may include a first coupling member (421) and a second coupling member (426). For example, the first coupling member (421) may be a base wheel or a drive wheel. For example, the second coupling member (426) may be a changeable wheel or a decoration wheel.

[0108] In one embodiment, the first coupling member (421) may be positioned opposite the coupling area (415). The first coupling member (421) may be fixed or coupled in a rotatably manner with respect to the housing structure (410).

[0109] In one embodiment, the second coupling member (426) can be selectively and removably coupled to the first coupling member (421). The second coupling member (426) can be coupled to the first coupling member (421) in an opposite direction to the housing structure (410) with respect to the first coupling member (421). The second coupling member (426) can be visually exposed to the exterior of the electronic device (400).

[0110] For example, the first coupling member (421) may be coupled to the coupling region (415) so as to be rotatable relative to the coupling region (415). The second coupling member (426) may be coupled to the first coupling member (421) and rotate together with it. Additionally, the second coupling member (426) may be optionally separable from the first coupling member (421).

[0111] In one embodiment of the present document, the rotation unit (420) can separate the second coupling member (426) from the electronic device (400) or attach the second coupling member (426) to the electronic device (400) by selectively separating the second coupling member (426). The second coupling member (426) can be easily and simply replaced as needed. For example, when replacement of properties such as shape, color, structure, material, or texture of the second coupling member (426) is required, the second coupling member (426) can be separated from the first coupling member (421) and replaced with another second coupling member (426).

[0112] In one embodiment of the present document, the electronic device (400) can efficiently replace the rotation unit (420) of the electronic device (400) by maintaining the rotation unit (420) and replacing only the second coupling member (426). For example, the first coupling member (421) may face the detent structure (430). Alternatively, by the rotation of the first coupling member (421), the input module (150) may receive an input signal of the electronic device (400). If the first coupling member (421) is separated from the housing structure (410), the detent structure (430) and / or the input module (150) may be exposed to the outside of the electronic device (400), and there may be a risk of loss or damage. Therefore, the electronic device (400) can prevent such a risk.

[0113] In one embodiment of the present document, the electronic device (400) can be replaced by selectively separating the second coupling member (426) among the rotation units (420), thereby preventing exposure of other components disposed between the first coupling member (421) and the housing structure (410), and reducing or blocking the risk of loss or damage of components of the electronic device (400).

[0114] In one embodiment of the present document, the electronic device (400) can easily separate only the second coupling member (426) while the first coupling member (421) remains coupled to the housing structure (410), and the second coupling member (426) can be maintained or selectively replaced, so that a part of the rotation unit (420) of the electronic device (400) can be easily and efficiently replaced.

[0115] For example, if the appearance of the electronic device (400) needs to be replaced according to the user's needs or preferences, the electronic device (400) according to one embodiment of the present document can easily separate the second coupling member (426) from the electronic device (400), and maintain or replace the second coupling member (426).

[0116] In one embodiment of the present document, the electronic device (400) can provide various usability to the user by easily replacing the second coupling member (426). In addition, the electronic device (400) can provide convenience to the user because it does not require separate specialized equipment or assistance from specialized personnel to replace the second coupling member (426). In one embodiment, the second coupling member (426) can be screw-coupled to the first coupling member (421). The first coupling member (421) can include a first screw (421a). The second coupling member (426) can include a second screw (426a) facing the first screw (421a). The first screw (421a) and the second screw (426a) can have shapes that correspond to each other. However, this is merely an example, and the first coupling member (421) and the second coupling member (426) can be detachably coupled in various ways.

[0117] In one embodiment of the present document, the first coupling member (421) and the second coupling member (426) are screw-coupled, so that the electronic device (400) can stably couple the first coupling member (421) and the second coupling member (426) so that the first coupling member (421) and the second coupling member (426) are not unnecessarily separated even in various situations (e.g., dropping or submersion).

[0118] In one embodiment, the second coupling member (426) can rotate independently of the first coupling member (421) while the rotation of the first coupling member (421) is restricted. For example, when the rotation of the first coupling member (421) is not restricted and the first coupling member (421) and / or the second coupling member (426) are rotated by an external force, the first coupling member (421) and the second coupling member (426) can rotate together in conjunction with each other.

[0119] In one embodiment, by rotating the second coupling member (426) independently of the first coupling member (421), the second coupling member (426) can be separated from the first coupling member (421), or coupled to the first coupling member (421).

[0120] For example, when the rotation of the first coupling member (421) is restricted and the second coupling member (426) is rotated by an external force, only the second coupling member (426) can rotate independently of the first coupling member (421). The second coupling member (426) can rotate independently of the first coupling member (421) and be separated from the first coupling member (421). Therefore, the electronic device (400) can temporarily restrict the rotation of the first coupling member (421) and allow the rotation of the second coupling member (426), thereby separating the second coupling member (426) from the first coupling member (421). Alternatively, when the second coupling member (426) is separated from the first coupling member (421), the second coupling member (426) can rotate independently of the first coupling member (421) and be coupled to the first coupling member (421). Accordingly, the electronic device (400) can temporarily limit the rotation of the first coupling member (421) and allow the rotation of the second coupling member (426), thereby coupling the second coupling member (426) to the first coupling member (421).

[0121] In one embodiment, the first coupling member (421) and the second coupling member (426) may be coupled by a screw thread formed to be coupled when rotated in a preset first direction (e.g., clockwise). For example, when the first coupling member (421) and the second coupling member (426) are at least partially separated or opposed to each other, when at least one of the first coupling member (421) and the second coupling member (426) is rotated in the first direction, the first screw (421a) and the second screw (426a) may interlock with each other, and the first coupling member (421) and the second coupling member (426) may be coupled.

[0122] In one embodiment, when the first coupling member (421) and the second coupling member (426) are coupled, the fixation of the first screw (421a) and the second screw (426a) can be maintained, and the first coupling member (421) and the second coupling member (426) can rotate together, unless the rotation of either of the first coupling member (421) and the second coupling member (426) is separately restricted.

[0123] For example, in a state where the first coupling member (421) and the second coupling member (426) are coupled, a force applied to the second wheel member (426) is transmitted to the first wheel member (421), so that the first wheel member (421) can move together in the moving direction of the second wheel member (426). Alternatively, in a state where the first wheel member (421) and the second wheel member (426) are coupled, a force applied to the first wheel member (421) is transmitted to the second wheel member (426), so that the second wheel member (426) can move together in the moving direction of the first wheel member (421).

[0124] In one embodiment, when an external force is applied to the second coupling member (426) while the rotation of the first coupling member (421) is restricted, the second coupling member (426) can rotate independently of the first coupling member (421).

[0125] For example, when the second coupling member (426) is rotated in a direction opposite to the first direction (e.g., counterclockwise) while the rotation of the first coupling member (421) is restricted, the first coupling member (421) is fixed, and only the second coupling member (426) can independently rotate in the counterclockwise direction. When the second coupling member (426) is rotated in the second direction relative to the first coupling member (421), the second coupling member (426) can be separated from the first coupling member (421) by the first screw (421a) and the second screw (426a).

[0126] In one embodiment, the first coupling member (421) may include a plurality of open areas (422). The plurality of open areas (422) may be arranged along the coupling area (415). The plurality of coupling areas (415) may be arranged at predetermined intervals. For example, with respect to the center of the annular first coupling member (421), the plurality of coupling areas (415) may be arranged at equal intervals of 15 degrees. However, the arrangement of the plurality of coupling areas (415) is not limited thereto, and may be formed at various intervals (e.g., 5 degrees or 10 degrees), or at least a portion of the plurality of coupling areas (415) may be formed at irregular intervals.

[0127] In one embodiment, the detent structure (430) may be provided at a position facing at least one of the plurality of open areas (422). For example, the electronic device (400) may include a plurality of detent structures (430). The plurality of detent structures (430) may be arranged at equal intervals. For example, the plurality of detent structures (430) may be arranged at equal intervals of 90 degrees with respect to the center of the first annular coupling member (421).

[0128] In one embodiment, the detent structure (430) can provide a detent force to the rotation unit (420) to resist rotation of the rotation unit (420). The detent structure (430) can support the rotation unit (420) so that it does not rotate when an external force is less than a certain range. When the external force is reduced while the rotation unit (420) is rotating, the detent structure (430) can assist the rotation unit (420) to move to its original position or an adjacent designated position.

[0129] In one embodiment, the detent structure (430) may include a movable member (431) and a spring (432). The movable member (431) may be inserted or removed into one of the plurality of open areas (422) and may impede rotation of the first engagement member (421). The spring (432) may support the movable member (431).

[0130] For example, the movable member (431) may have a shape that is insertable into a plurality of open areas (422). When the rotation unit (420) rotates, the movable member (431) may be pressed in one direction (e.g., in the -Z direction) by the rotation unit (420). The spring (432) may resist the movable member (431) from moving in one direction. The movable member (431) may move between the plurality of open areas (422) in conjunction with the rotation of the rotation unit (420), and the detent structure (430) may provide a detent force to the rotation unit (420).

[0131] In one embodiment, the detent structure (430) can guide the locking unit (440) and the plurality of open areas (422) to be arranged opposite each other. In one embodiment, the locking unit (440) can be coupled with the plurality of open areas (422) formed for an interlocking relationship with the detent structure (430). The electronic device (400) can separate the second engaging member (426) from the first engaging member (421) by utilizing the configuration for detent actuation. The electronic device (400) can provide structural efficiency and manufacturing efficiency.

[0132] Hereinafter, the configuration and structure of a locking unit (440) according to one embodiment of the present document will be described, but this is merely an example of one of various implementation examples of the electronic device (400) and the locking unit (440), and the actual implementation of the electronic device (400) is not limited thereto.

[0133] In one embodiment, the locking unit (440) can be configured to be insertable into at least one of the plurality of open areas (422). The locking unit (440) can selectively limit the rotation of the first coupling member (421). When the locking unit (440) limits the rotation of the first coupling member (421), the second coupling member (426) can be made rotatable independently of the first coupling member (421). By allowing the second coupling member (426) to rotate independently of the first coupling member (421), the second coupling member (426) can be separated from the first coupling member (421) or coupled to the first coupling member (421).

[0134] In one embodiment, the locking unit (440) may include a locking pin (441) for limiting rotation of the first coupling member (421). The housing structure (410) may include a first hole (411a). The first hole (411a) may be formed in the first surface (411). The first hole (411a) may be arranged to face any one of the plurality of open areas (422) in the coupling area (415).

[0135] In one embodiment, the locking pin (441) can protrude from the first hole (411a) in a pressurized state and move into one of the plurality of open areas (422). The locking pin (441) can be inserted into one of the open areas (422) in a pressurized state to engage with the first coupling member (421), and the locking pin (441) can limit the rotation of the first coupling member (421).

[0136] In one embodiment, the locking pin (441) may include a protruding region (441a) and a pressing surface (441b). The protruding region (441a) may be a region that is inserted into one of the plurality of open regions (422) when pressed. The pressing surface (441b) may be a surface of the locking pin (441) that is pressed by an external force. The protruding region (441a) and the pressing surface (441b) may be provided at opposite positions on the locking pin (441). For example, when the pressing surface (441b) is pressed by an external force, the protruding region (441a) may protrude from the first hole (411a) and be inserted into one of the plurality of open regions (422).

[0137] For example, as illustrated in FIG. 4d, in a state where no external force is applied to the pressurized surface (441b) (e.g., initial state), the protruding region (441a) of the locking pin (441) may be positioned outside the open region (422) or spaced apart from the open region (422). Accordingly, the locking pin (441) may not restrict the rotation of the first coupling member (421).

[0138] For example, as illustrated in FIG. 4e, when the pressurized surface (441b) is pressed by the ejector (E), the locking pin (441) rises and the protruding region (441a) can be inserted into one of the open regions (422). Accordingly, the locking pin (441) can limit the rotation of the first coupling member (421).

[0139] In one embodiment, the locking unit (440) may further include at least some of a locking housing (443), an elastic body (445), and a support area (447).

[0140] In one embodiment, the elastic body (445) can transmit an elastic force to the locking pin (441) so that the locking pin (441) returns to its position before being pressed (e.g., its initial position). For example, when the locking pin (441) is pressed by the ejector (E), the elastic body (445) can be compressed (e.g., the state of FIG. 4e). When the ejector (E) is removed, the locking pin (441) can return to its initial position by the elastic force of the elastic body (445) (e.g., the state of FIG. 4d).

[0141] In one embodiment, the support area (447) can support the locking pin (441) in a position before the locking pin (441) is pressed (e.g., an initial position). The support area (447) can support the locking pin (441) so that it does not come off or break due to the elastic force of the elastic body (445) or an external force.

[0142] In one embodiment, the housing structure (410) may include a third hole (413a). The third hole (413a) may be provided on the third surface (413) of the housing structure (410). The third hole (413a) may be a hole into which an ejector (E) is inserted. The third hole (413a) may be arranged to face the pressurizing surface (441b).

[0143] In one embodiment, the third hole (413a) may be formed to be inclined at a predetermined angle in the direction in which the locking pin (441) moves (e.g., +Z direction) with respect to the third surface (413). By forming the third hole (413a) to be inclined, the third hole (413a) may guide the direction in which the ejector (E) is inserted. However, the inclination of the third hole (413a) is only one exemplary embodiment for the electronic device (400), and the third hole (413a) may extend substantially horizontally (e.g., in the XY plane direction).

[0144] In one embodiment, the housing structure (410) may include a third screw (413b) surrounding a third hole (413a). The third screw (413b) may extend along the direction in which the third hole (413a) extends. An ejector (E) may be inserted through the third screw (413b). The ejector (E) may be rotatably inserted into the third hole (413a) to press the pressurizing surface (441b). Accordingly, the force of the ejector (E) rotating may apply pressure to the pressurizing surface (441b) to raise the locking pin (441). The raised locking pin (441) may restrict the rotation of the first coupling member (421). However, the third screw (413b) is merely one exemplary embodiment of the electronic device (400), and the third screw (413b) may be omitted.

[0145] In one embodiment, the locking housing (443) may form the outer appearance of the locking unit (440). Alternatively, the locking housing (443) may accommodate or support other configurations of the locking unit (440). The locking housing (443) accommodates the locking unit (440) and may be disposed on the inside of the housing structure (410). For example, the housing structure (410) may include a receiving groove (410a) for accommodating the locking housing (443). The receiving groove (410a) may be provided on the inner surface of the housing structure (410). The receiving groove (410a) may have a shape and size corresponding to the locking housing (443).

[0146] In one embodiment, an adhesive member (433) may be provided on one side of the locking housing (443). The adhesive member (433) may adhere the locking housing (443) to the housing structure (410). The adhesive member (433) may be positioned on one side facing the receiving groove (410a). For example, an adhesive surface (410b) may be provided on the receiving groove (410a). The adhesive surface (410b) may be a surface facing the adhesive member (433) or an area where the adhesive member (433) is coupled.

[0147] In one embodiment, the locking housing (443) may include a fourth hole (443a) facing the first hole (411a) and a fifth hole (443b) facing the third hole (413a). An ejector (E) may be inserted into the fifth hole (443b). A protruding area (441a) of the locking pin (441) may be arranged in the third hole (413a).

[0148] In one embodiment of the present document, the ejector (E) can be inserted toward the third surface (413) of the housing structure (410) through the third hole (413a) and the fifth hole (443b). The electronic device (400) can prevent the locking pin (441) from moving unnecessarily. In addition, the electronic device (400) can easily and simply limit the rotation of the first coupling member (421) through the ejector (E). A user can easily and simply separate the second coupling member (426) from the first coupling member (421) or replace the second coupling member (426) using the ejector (E) without the intervention of a specialist or specialized equipment.

[0149] FIG. 5a is an exploded perspective view of an electronic device (500) according to one embodiment, FIG. 5b is a plan view of an electronic device (500) according to one embodiment, and FIGS. 5c, 5d, and 5e are cross-sectional views of an electronic device (500) according to one embodiment.

[0150] Specifically, FIG. 5b is a plan view and an enlarged view of a portion of an electronic device (400) omitting some components of the electronic device (500) (e.g., the second coupling member (526) of the rotation unit (520)), FIG. 5c is a cross-sectional view of the electronic device (500) viewed in the C-C' direction of FIG. 5b, and FIGS. 5d and 5e are cross-sectional views of the electronic device (500) viewed in the D-D' direction of FIG. 5b.

[0151] Referring to FIGS. 5A, 5B, 5C, 5D, and 5E, an electronic device (500) according to an embodiment (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2A and 2B, or the electronic device (300) of FIGS. 3A and 3B) may include at least a portion of a housing structure (510) (e.g., the housing (210) of FIGS. 2A and 2B, the housing (310) of FIGS. 3A and 3B), a rotation unit (520) (e.g., the wheel key (320) of FIG. 3A), and a locking unit (540).

[0152] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that some components and structures of the electronic device (500) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the electronic device (500) unless it is technically clearly impossible.

[0153] In one embodiment, the electronic device (500) may be a wearable device that can be attached to a part of the body, such as a smartwatch. Alternatively, and not limited thereto, the electronic device (500) may be any one of various types of devices, such as a wireless communication device, a display device, a home appliance, an industrial device, or a computer processing device.

[0154] In one embodiment, the housing structure (510) may form the exterior of the electronic device (500). Alternatively, the housing structure (510) may accommodate, support, and / or protect electrical components of the electronic device (500). Alternatively, the housing structure (510) may be the body or main body of the electronic device (500).

[0155] In one embodiment, the housing structure (510) may include a first side (511), a second side (512), and a third side (513). The first side (511) may be a side or a front side facing one direction (e.g., +Z direction). A bonding area (515) may be provided on the first side (511). The second side (512) may be a side or a back side facing a direction opposite to the first side (511) (e.g., -Z direction). The third side (513) may be a side extending from the first side (511) to the second side (512), for example, a side surface.

[0156] In one embodiment, the housing structure (510) may include a coupling area (515). The coupling area (515) may be an area to which the rotation unit (520) is coupled. The shape, structure, and size of the coupling area (515) are not limited, and may have a shape surrounding the opening at the center of the housing structure (510), as illustrated in FIG. 5A. For example, the coupling area (515) may have an annular or ring-shaped shape. Alternatively, the coupling area (515) may have a shape corresponding to the shape of the rotation unit (520).

[0157] In one embodiment, the rotation unit (520) may be rotatably attached to the coupling area (515). The rotation unit (520) may be rotated clockwise and / or counterclockwise with respect to a state facing the front of the electronic device (500) (e.g., the state of FIG. 5b).

[0158] In one embodiment, an input module of an electronic device (500) (e.g., input module (150) of FIG. 1) can detect a rotational state of a rotational unit (520). Alternatively, the rotational unit (520) may be a part of the input module (150). The input module (150) can acquire information about a rotational state of the rotational unit (520) (e.g., rotational direction, rotational angle, rotational degree, and / or rotational speed).

[0159] In one embodiment, at least one processor (e.g., processor (120) of FIG. 1) of the electronic device (500) may receive a detection result from the input module (150). The processor (120) may control the operation of the electronic device (500) based on the rotational state of the rotation unit (520).

[0160] In one embodiment of the present document, the electronic device (500) can receive input information for driving the electronic device (500) through the rotation unit (520). The user can easily, simply, and intuitively control the driving of the electronic device (500) by rotating the rotation unit (520). In addition, the electronic device (500) can omit an additional input switch or input key by including the rotation unit (520), and the rotation unit (520) can provide manufacturing efficiency and space efficiency of the electronic device (500).

[0161] In one embodiment, a guide member (509) may be provided between the housing structure (510) and the rotation unit (520). The guide member (509) may support the rotation unit (520) so that it is rotatably fastened to the housing structure (510). Alternatively, the guide member (509) may support the rotation unit (520) so that the rotation unit (520) does not come off during rotational driving, or may guide the rotation of the rotation unit (520).

[0162] In one embodiment, the rotation unit (520) may include a first coupling member (521) and a second coupling member (526). For example, the first coupling member (521) may be a base wheel or a drive wheel. For example, the second coupling member (526) may be a changeable wheel or a decoration wheel.

[0163] In one embodiment, the first coupling member (521) may be positioned opposite the coupling area (515). The first coupling member (521) may be fixed or coupled in a rotatably manner with respect to the housing structure (510).

[0164] In one embodiment, the second coupling member (526) can be selectively and removably coupled to the first coupling member (521). The second coupling member (526) can be coupled to the first coupling member (521) in an opposite direction to the housing structure (510) with respect to the first coupling member (521). The second coupling member (526) can be visually exposed to the exterior of the electronic device (500).

[0165] For example, a first coupling member (521) may be coupled to a coupling region (515) so as to be rotatable relative to the coupling region (515). A second coupling member (526) may be coupled to the first coupling member (521) and rotate together with the first coupling member (521). Additionally, the second coupling member (526) may be optionally separable from the first coupling member (521).

[0166] In one embodiment of the present document, the rotation unit (520) can separate the second coupling member (526) from the electronic device (500) or attach the second coupling member (526) to the electronic device (500) by selectively separating the second coupling member (526). The second coupling member (526) can be easily and simply replaced as needed. For example, when replacement of properties such as shape, color, structure, material, or texture of the second coupling member (526) is required, the second coupling member (526) can be separated from the first coupling member (521) and replaced with another second coupling member (526).

[0167] In one embodiment of the present document, the electronic device (500) can efficiently replace the rotation unit (520) of the electronic device (500) by maintaining the first rotation unit (520) and replacing only the second coupling member (526). For example, the first coupling member (521) may face the detent structure (530). Alternatively, by the rotation of the first coupling member (521), the input module (150) may receive an input signal of the electronic device (500). If the first coupling member (521) is separated from the housing structure (510), the detent structure (530) and / or the input module (150) may be exposed to the outside of the electronic device (500), and there may be a risk of loss or damage. Therefore, the electronic device (500) can prevent such a risk.

[0168] In one embodiment of the present document, the electronic device (500) can be replaced by selectively separating the second coupling member (526) among the rotation units (520), thereby preventing exposure of other components disposed between the first coupling member (521) and the housing structure (510), and reducing or preventing the risk of loss or damage of components of the electronic device (500).

[0169] In one embodiment of the present document, the electronic device (500) can easily separate only the second coupling member (526) while the first coupling member (521) remains coupled to the housing structure (510), and the second coupling member (526) can be maintained or selectively replaced, so that a part of the rotation unit (520) of the electronic device (500) can be easily and efficiently replaced.

[0170] For example, if the appearance of the electronic device (500) needs to be replaced according to the user's needs or preferences, the electronic device (500) according to one embodiment of the present document can easily separate the second coupling member (526) from the electronic device (500), and maintain or replace the second coupling member (526).

[0171] In one embodiment of the present document, the electronic device (500) can provide various usability to the user by easily replacing the second coupling member (526). In addition, the electronic device (500) can provide convenience to the user because it does not require separate specialized equipment or assistance from specialized personnel to replace the second coupling member (526).

[0172] In one embodiment, the second coupling member (526) may be screw-coupled to the first coupling member (521). The first coupling member (521) may include a first screw (521a). The second coupling member (526) may include a second screw (526a) facing the first screw (521a). The first screw (521a) and the second screw (526a) may have shapes that correspond to each other. However, this is merely an example, and the first coupling member (521) and the second coupling member (526) may be releasably coupled in various ways.

[0173] In one embodiment of the present document, the first coupling member (521) and the second coupling member (526) are screw-coupled, so that the electronic device (500) can stably couple the first coupling member (521) and the second coupling member (526) so that the first coupling member (521) and the second coupling member (526) are not unnecessarily separated even in various situations (e.g., dropping or submersion).

[0174] In one embodiment, the second coupling member (526) can rotate independently of the first coupling member (521) while the rotation of the first coupling member (521) is restricted. For example, when the rotation of the first coupling member (521) is not restricted and the first coupling member (521) and / or the second coupling member (526) are rotated by an external force, the first coupling member (521) and the second coupling member (526) can rotate together in conjunction with each other.

[0175] In one embodiment, by rotating the second coupling member (526) independently of the first coupling member (521), the second coupling member (526) can be separated from the first coupling member (521), or coupled to the first coupling member (521).

[0176] For example, when the rotation of the first coupling member (521) is restricted and the second coupling member (526) is rotated by an external force, only the second coupling member (526) can rotate independently of the first coupling member (521). The second coupling member (526) can rotate independently of the first coupling member (521) and be separated from the first coupling member (521). Therefore, the electronic device (500) can temporarily restrict the rotation of the first coupling member (521) and allow the rotation of the second coupling member (526), ​​thereby separating the second coupling member (526) from the first coupling member (521). Alternatively, when the second coupling member (526) is separated from the first coupling member (521), the second coupling member (526) can rotate independently of the first coupling member (521) and be coupled to the first coupling member (521). Accordingly, the electronic device (500) can temporarily limit the rotation of the first coupling member (521) and allow the rotation of the second coupling member (526), ​​thereby coupling the second coupling member (526) to the first coupling member (521).

[0177] In one embodiment, the first coupling member (521) and the second coupling member (526) may be coupled by a screw thread formed to be coupled when rotated in a first predetermined direction (e.g., clockwise). For example, when the first coupling member (521) and the second coupling member (526) are at least partially separated or opposed to each other, when at least one of the first coupling member (521) and the second coupling member (526) is rotated in the first direction, the first screw (521a) and the second screw (526a) may interlock with each other, and the first coupling member (521) and the second coupling member (526) may be coupled.

[0178] In one embodiment, when the first coupling member (521) and the second coupling member (526) are coupled, the fixation of the first screw (521a) and the second screw (526a) can be maintained, and the first coupling member (521) and the second coupling member (526) can rotate together, unless the rotation of either of the first coupling member (521) and the second coupling member (526) is separately restricted.

[0179] For example, when the first coupling member (521) and the second coupling member (526) are coupled, a force applied to the second wheel member (526) is transmitted to the first wheel member (521), so that the first wheel member (521) can move together in the moving direction of the second wheel member (526). Alternatively, when the first wheel member (521) and the second wheel member (526) are coupled, a force applied to the first wheel member (521) is transmitted to the second wheel member (526), ​​so that the second wheel member (526) can move together in the moving direction of the first wheel member (521).

[0180] In one embodiment, when an external force is applied to the second coupling member (526) while the rotation of the first coupling member (521) is restricted, the second coupling member (526) can rotate independently of the first coupling member (521).

[0181] For example, when the second coupling member (526) is rotated in a direction opposite to the first direction (e.g., counterclockwise) while the rotation of the first coupling member (521) is restricted, the first coupling member (521) is fixed, and only the second coupling member (526) can independently rotate in the counterclockwise direction. When the second coupling member (526) is rotated in the second direction relative to the first coupling member (521), the second coupling member (526) can be separated from the first coupling member (521) by the first screw (521a) and the second screw (526a).

[0182] In one embodiment, the first coupling member (521) may include a plurality of open areas (522). The plurality of open areas (522) may be arranged along the coupling area (515). The plurality of coupling areas (515) may be arranged at predetermined intervals. For example, with respect to the center of the annular first coupling member (521), the plurality of coupling areas (515) may be arranged at equal intervals of 15 degrees. However, the arrangement of the plurality of coupling areas (515) is not limited thereto, and may be formed at various intervals (e.g., 5 degrees or 10 degrees), or at least a portion of the plurality of coupling areas (515) may be formed at irregular intervals.

[0183] In one embodiment, the detent structure (530) may be provided at a position opposite to at least one of the plurality of open areas (522). For example, the electronic device (500) may include a plurality of detent structures (530). The plurality of detent structures (530) may be arranged at equal intervals. For example, the plurality of detent structures (530) may be arranged at equal intervals of 90 degrees with respect to the center of the first annular coupling member (521).

[0184] In one embodiment, the detent structure (530) can provide a detent force to the rotation unit (520) to resist rotation of the rotation unit (520). The detent structure (530) can support the rotation unit (520) so that it does not rotate when an external force is less than a certain range. When the external force is reduced while the rotation unit (520) is rotating, the detent structure (530) can assist the rotation unit (520) to move to its original position or an adjacent designated position.

[0185] In one embodiment, the detent structure (530) may include a movable member (531) and a spring (532). The movable member (531) may be inserted or removed into one of the plurality of open areas (522) and may impede rotation of the first engagement member (521). The spring (532) may support the movable member (531).

[0186] For example, the movable member (531) may have a shape that is insertable into a plurality of open areas (522). When the rotation unit (520) rotates, the movable member (531) may be pressed in one direction (e.g., in the -Z direction) by the rotation unit (520). The spring (532) may resist the movable member (531) from moving in one direction. The movable member (531) may move between the plurality of open areas (522) in conjunction with the rotation of the rotation unit (520), and the detent structure (530) may provide a detent force to the rotation unit (520).

[0187] In one embodiment, the detent structure (530) can guide the locking unit (540) and the plurality of open areas (522) to be arranged opposite each other. In one embodiment, the locking unit (540) can be coupled with the plurality of open areas (522) formed for an interlocking relationship with the detent structure (530). The electronic device (500) can utilize the configuration for detent actuation to separate the second engaging member (526) from the first engaging member (521). The electronic device (500) can provide structural efficiency and manufacturing efficiency.

[0188] Hereinafter, the configuration and structure of a locking unit (540) according to one embodiment of the present document will be described, but this is only an example of one of various implementation examples of the electronic device (500) and the locking unit (540), and the actual implementation of the electronic device (500) is not limited thereto.

[0189] In one embodiment, the locking unit (540) can be configured to be insertable into at least one of the plurality of open areas (522). The locking unit (540) can selectively limit the rotation of the first coupling member (521). When the locking unit (540) limits the rotation of the first coupling member (521), the second coupling member (526) can be made rotatable independently of the first coupling member (521). By allowing the second coupling member (526) to rotate independently of the first coupling member (521), the second coupling member (526) can be separated from the first coupling member (521) or coupled to the first coupling member (521).

[0190] In one embodiment, the locking unit (540) may include a locking pin (541) for limiting rotation of the first coupling member (521). The housing structure (510) may include a first hole (511a). The first hole (511a) may be formed in the first surface (511). The first hole (511a) may be arranged to face any one of the plurality of open areas (522) in the coupling area (515).

[0191] In one embodiment, the locking pin (541) can protrude from the first hole (511a) in a pressurized state and move into one of the plurality of open areas (522). The locking pin (541) can be inserted into one of the open areas (522) in a pressurized state to engage with the first coupling member (521), and the locking pin (541) can limit the rotation of the first coupling member (521).

[0192] In one embodiment, the locking pin (541) may include a protruding region (541a) and a pressing surface (541b). The protruding region (541a) may be an area that is inserted into one of the plurality of open regions (522) when pressed.

[0193] In one embodiment, the pressing surface (541b) may be one surface of the locking pin (541) that is pressed by an external force. The protruding region (541a) and the pressing surface (541b) may be provided at opposite positions on the locking pin (541).

[0194] For example, when the pressurized surface (541b) is pressed by an external force, the protruding region (541a) can protrude from the first hole (511a) and be inserted into one of the plurality of open regions (522).

[0195] For example, as illustrated in FIG. 5d, in a state where no external force is applied to the pressurized surface (541b) (e.g., initial state), the protruding region (541a) of the locking pin (541) may be positioned outside the open region (522) or spaced apart from the open region (522). Accordingly, the locking pin (541) may not restrict the rotation of the first coupling member (521).

[0196] For example, as illustrated in FIG. 5e, when the pressurized surface (541b) is pressed, the locking pin (541) rises and the protruding region (541a) can be inserted into one of the open regions (522). Accordingly, the locking pin (541) can limit the rotation of the first coupling member (521).

[0197] In one embodiment, the locking unit (540) may further include an elastic body (545). In one embodiment, the elastic body (545) may transmit an elastic force to the locking pin (541) so that the locking pin (541) returns to its position before being pressed (e.g., its initial position). For example, when the locking pin (541) is pressed, the elastic body (545) may be compressed (e.g., the state of FIG. 5e). When the force pressing the locking pin (541) is reduced or removed, the locking pin (541) may return to its initial position by the elastic force of the elastic body (545) (e.g., the state of FIG. 5d).

[0198] In one embodiment, the housing structure (510) may include a second hole (512a). The second hole (512a) may be provided on the second surface (512) of the housing structure (510). The second hole (512a) may be a hole for pressing a pressing surface (541b) from the outside of the housing structure (510). The pressing surface (541b) may be positioned so as to be exposed to the outside of the housing structure (510) through the second hole (512a) based on the initial position before the locking pin (541) is pressed (e.g., the state of FIG. 5d). The pressing surface (541b) may be pressed by a user or an external structure (e.g., an ejector (E)) and may move in one direction (e.g., the +Z direction).

[0199] In one embodiment, the housing structure (510) may further include a cover member (519). The cover member (519) may form a second surface (512) of the housing structure (510). A second hole (512a) may be provided in the cover member (519). The cover member (519) may accommodate at least a portion of the locking pin (541). Alternatively, without limitation, the cover member (519) may be implemented as a separate configuration from the housing structure (510). For example, the cover member (519) may be coupled to the second surface (512) of the housing structure (510). The locking pin (541) may protrude beyond the second hole (512a), and the protruding portion may be accommodated in the cover member (519).

[0200] In one embodiment of the present document, the locking pin (541) can limit the rotation of the first coupling member (521) by being pressed through the second surface (512) of the electronic device (500). The second surface (512) may be the back surface of the electronic device (500), and the second hole (512a) is arranged in the second surface (512), so that the electronic device (500) can prevent the locking pin (541) from moving unnecessarily. In addition, the electronic device (500) can easily and simply limit the rotation of the first coupling member (521) through the pressing surface (541b) that is visually exposed to the outside. A user can easily and simply separate the second coupling member (526) from the first coupling member (521) or replace the second coupling member (526) by pressing the pressing surface (541b) without the intervention of a specialist or specialized equipment.

[0201] FIG. 6a is an exploded perspective view of an electronic device (600) according to one embodiment, FIG. 6b is a plan view of an electronic device (600) according to one embodiment, and FIG. 6c is a cross-sectional view of an electronic device (600) according to one embodiment.

[0202] Specifically, FIG. 6c is a cross-sectional view of the electronic device (600) viewed in the F-F' direction of FIG. 6b.

[0203] Referring to FIGS. 6A, 6B, and 6B, an electronic device (600) according to an embodiment (e.g., an electronic device (101) of FIG. 1, an electronic device (200) of FIGS. 2A and 2B, an electronic device (300) of FIGS. 3A and 3B, an electronic device (400) of FIGS. 4A, 4B, 4C, 4D, and 4E, or an electronic device (500) of FIGS. 5A, 5B, 5C, 5D, and 5E) includes a housing structure (610) (e.g., a housing (210) of FIGS. 2A and 2B, a housing (310) of FIGS. 3A and 3B, a housing structure (410) of FIGS. 4A, 4B, 4C, 4D, and 4E, or a housing structure (410) of FIGS. 5A, 5B, 5C, 5D, and 5E). The housing structure (510) of 5e) and the rotation unit (620) (e.g., the wheel key (320) of FIG. 3a, the rotation unit (420) of FIGS. 4a, 4b, 4c, 4d and 4e or the rotation unit (520) of FIGS. 5a, 5b, 5c, 5d and 5e) may be included at least a part.

[0204] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the electronic device (600) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the electronic device (600) unless it is technically clearly impossible.

[0205] In one embodiment, the electronic device (600) may be a wearable device that can be attached to a part of the body, such as a smartwatch. Alternatively, and not limited thereto, the electronic device (600) may be any one of various types of devices, such as a wireless communication device, a display device, a home appliance, an industrial device, or a computer processing device.

[0206] In one embodiment, the housing structure (610) may form the exterior of the electronic device (600). Alternatively, the housing structure (610) may accommodate, support, and / or protect electrical components of the electronic device (600). Alternatively, the housing structure (610) may be the body or main body of the electronic device (600).

[0207] In one embodiment, the housing structure (610) may include a first side (611), a second side (612), and a third side (613). The first side (611) may be a side or a front side facing one direction (e.g., +Z direction). A bonding area (615) may be provided on the first side (611). The second side (612) may be a side or a back side facing a direction opposite to the first side (611) (e.g., -Z direction). The third side (613) may be a side extending from the first side (611) to the second side (612), for example, a side surface.

[0208] In one embodiment, the housing structure (610) may include a coupling area (615). The coupling area (615) may be an area to which the rotation unit (620) is coupled. The shape, structure, and size of the coupling area (615) are not limited, and may have a shape surrounding the opening at the center of the housing structure (610), as illustrated in FIG. 6A. For example, the coupling area (615) may have an annular or ring-shaped shape. Alternatively, the coupling area (615) may have a shape corresponding to the shape of the rotation unit (620).

[0209] In one embodiment, the rotation unit (620) may be rotatably fastened to the coupling area (615). The rotation unit (620) may be rotated clockwise and / or counterclockwise with respect to a state facing the front of the electronic device (600) (e.g., the state of FIG. 6B).

[0210] In one embodiment, an input module of an electronic device (600) (e.g., input module (150) of FIG. 1) can detect a rotational state of a rotational unit (620). Alternatively, the rotational unit (620) may be a part of the input module (150). The input module (150) can acquire information about a rotational state of the rotational unit (620) (e.g., rotational direction, rotational angle, rotational degree, and / or rotational speed).

[0211] In one embodiment, at least one processor (e.g., processor (120) of FIG. 1) of the electronic device (600) may receive a detection result from the input module (150). The processor (120) may control the operation of the electronic device (600) based on the rotational state of the rotation unit (620).

[0212] In one embodiment of the present document, the electronic device (600) can receive input information for driving the electronic device (600) through the rotation unit (620). The user can easily, simply, and intuitively control the driving of the electronic device (600) by rotating the rotation unit (620). In addition, the electronic device (600) can omit an additional input switch or input key by including the rotation unit (620), and the rotation unit (620) can provide manufacturing efficiency and space efficiency of the electronic device (600).

[0213] In one embodiment, a guide member (609) may be provided between the housing structure (610) and the rotation unit (620). The guide member (609) may support the rotation unit (620) so that it is rotatably fastened to the housing structure (610). Alternatively, the guide member (609) may support the rotation unit (620) so that the rotation unit (620) does not come off during rotational driving, or may guide the rotation of the rotation unit (620).

[0214] In one embodiment, the rotation unit (620) may include a first coupling member (621) and a second coupling member (626). For example, the first coupling member (621) may be a base wheel or a drive wheel. For example, the second coupling member (626) may be a changeable wheel or a decoration wheel.

[0215] In one embodiment, the first coupling member (621) may be positioned opposite the coupling area (615). The first coupling member (621) may be fixed or coupled in a rotatably manner with respect to the housing structure (610).

[0216] In one embodiment, the second coupling member (626) can be selectively and removably coupled to the first coupling member (621). The second coupling member (626) can be coupled to the first coupling member (621) in an opposite direction to the housing structure (610) with respect to the first coupling member (621). The second coupling member (626) can be visually exposed to the exterior of the electronic device (600).

[0217] For example, a first coupling member (621) may be coupled to a coupling region (615) so as to be rotatable relative to the coupling region (615). A second coupling member (626) may be coupled to the first coupling member (621) so as to be rotatable together with the first coupling member (621). Additionally, the second coupling member (626) may be optionally separable from the first coupling member (621).

[0218] In one embodiment of the present document, the rotation unit (620) can separate the second coupling member (626) from the electronic device (600) or attach the second coupling member (626) to the electronic device (600) by selectively separating the second coupling member (626). The second coupling member (626) can be easily and simply replaced as needed. For example, when replacement of properties such as shape, color, structure, material, or texture of the second coupling member (626) is required, the second coupling member (626) can be separated from the first coupling member (621) and replaced with another second coupling member (626).

[0219] In one embodiment of the present document, the electronic device (600) can efficiently replace the rotation unit (620) of the electronic device (600) by maintaining the first rotation unit (620) and replacing only the second coupling member (626). For example, the first coupling member (621) may face the detent structure (630). Alternatively, by the rotation of the first coupling member (621), the input module (150) may receive an input signal of the electronic device (600). If the first coupling member (621) is separated from the housing structure (610), the detent structure (630) and / or the input module (150) may be exposed to the outside of the electronic device (600), and there may be a risk of loss or damage. Therefore, the electronic device (600) can prevent such a risk.

[0220] In one embodiment of the present document, the electronic device (600) can be replaced by selectively separating the second coupling member (626) among the rotation units (620), thereby preventing exposure of other components disposed between the first coupling member (621) and the housing structure (610), and reducing or preventing the risk of loss or damage of components of the electronic device (600).

[0221] In one embodiment of the present document, the electronic device (600) can easily separate only the second coupling member (626) while the first coupling member (621) remains coupled to the housing structure (610), and the second coupling member (626) can be maintained or selectively replaced, so that some components of the rotation unit (620) of the electronic device (600) can be easily and efficiently replaced.

[0222] For example, if the appearance of the electronic device (600) needs to be replaced according to the user's needs or preferences, the electronic device (600) according to one embodiment of the present document can easily separate the second coupling member (626) from the electronic device (600), and maintain or replace the second coupling member (626).

[0223] In one embodiment of the present document, the electronic device (600) can provide various usability to the user by easily replacing the second coupling member (626). In addition, the electronic device (600) can provide convenience to the user because it does not require separate specialized equipment or assistance from specialized personnel to replace the second coupling member (626).

[0224] In one embodiment, the second coupling member (626) may be screw-coupled to the first coupling member (621). The first coupling member (621) may include a first screw (621a). The second coupling member (626) may include a second screw (626a) facing the first screw (621a). The first screw (621a) and the second screw (626a) may have corresponding shapes. However, this is merely an example, and the first coupling member (621) and the second coupling member (626) may be releasably coupled in various ways.

[0225] In one embodiment of the present document, the first coupling member (621) and the second coupling member (626) are screw-coupled, so that the electronic device (600) can stably couple the first coupling member (621) and the second coupling member (626) so that the first coupling member (621) and the second coupling member (626) are not unnecessarily separated even in various situations (e.g., dropping or submersion).

[0226] In one embodiment, the second coupling member (626) can rotate independently of the first coupling member (621) while the rotation of the first coupling member (621) is restricted. For example, when the rotation of the first coupling member (621) is not restricted and the first coupling member (621) and / or the second coupling member (626) are rotated by an external force, the first coupling member (621) and the second coupling member (626) can rotate together in conjunction with each other.

[0227] In one embodiment, by rotating the second coupling member (626) independently of the first coupling member (621), the second coupling member (626) can be separated from the first coupling member (621), or coupled to the first coupling member (621).

[0228] For example, when the rotation of the first coupling member (621) is restricted and the second coupling member (626) is rotated by an external force, only the second coupling member (626) can rotate independently of the first coupling member (621). The second coupling member (626) can rotate independently of the first coupling member (621) and be separated from the first coupling member (621). Therefore, the electronic device (600) can temporarily restrict the rotation of the first coupling member (621) and allow the rotation of the second coupling member (626), thereby separating the second coupling member (626) from the first coupling member (621). Alternatively, when the second coupling member (626) is separated from the first coupling member (621), the second coupling member (626) can rotate independently of the first coupling member (621) and be coupled to the first coupling member (621). Accordingly, the electronic device (600) can temporarily limit the rotation of the first coupling member (621) and allow the rotation of the second coupling member (626), thereby coupling the second coupling member (626) to the first coupling member (621).

[0229] In one embodiment, the first coupling member (621) and the second coupling member (626) may be coupled by a screw thread formed to be coupled when rotated in a first predetermined direction (e.g., clockwise). For example, when the first coupling member (621) and the second coupling member (626) are at least partially separated or opposed to each other, when at least one of the first coupling member (621) and the second coupling member (626) is rotated in the first direction, the first screw (621a) and the second screw (626a) may interlock with each other, and the first coupling member (621) and the second coupling member (626) may be coupled.

[0230] In one embodiment, when the first coupling member (621) and the second coupling member (626) are coupled, the fixation of the first screw (621a) and the second screw (626a) can be maintained, and the first coupling member (621) and the second coupling member (626) can rotate together, unless the rotation of either the first coupling member (621) or the second coupling member (626) is separately restricted.

[0231] For example, when the first coupling member (621) and the second coupling member (626) are coupled, a force applied to the second wheel member (626) is transmitted to the first wheel member (621), so that the first wheel member (621) can move together in the moving direction of the second wheel member (626). Alternatively, when the first wheel member (621) and the second wheel member (626) are coupled, a force applied to the first wheel member (621) is transmitted to the second wheel member (626), so that the second wheel member (626) can move together in the moving direction of the first wheel member (621).

[0232] In one embodiment, when an external force is applied to the second coupling member (626) while the rotation of the first coupling member (621) is restricted, the second coupling member (626) can rotate independently of the first coupling member (621).

[0233] For example, when the second coupling member (626) is rotated in a direction opposite to the first direction (e.g., counterclockwise) while the rotation of the first coupling member (621) is restricted, the first coupling member (621) is fixed, and only the second coupling member (626) can independently rotate in the counterclockwise direction. When the second coupling member (626) is rotated in the second direction relative to the first coupling member (621), the second coupling member (626) can be separated from the first coupling member (621) by the first screw (621a) and the second screw (626a).

[0234] In one embodiment, the first coupling member (621) may include a plurality of open areas (622). The plurality of open areas (622) may be arranged along the coupling area (615). The plurality of coupling areas (615) may be arranged at predetermined intervals. For example, with respect to the center of the annular first coupling member (621), the plurality of coupling areas (615) may be arranged at equal intervals of 15 degrees. However, the arrangement of the plurality of coupling areas (615) is not limited thereto, and may be formed at various intervals (e.g., 5 degrees or 10 degrees), or at least a portion of the plurality of coupling areas (615) may be formed at irregular intervals.

[0235] In one embodiment, the second coupling member (626) may include a sixth hole (626b). The sixth hole (626b) may be positioned opposite any one of the plurality of open areas (622). For example, the sixth hole (626b) may be formed on an outer side surface of the second coupling member (626).

[0236] In one embodiment, an ejector (E) may be inserted into the sixth hole (626b). The ejector (E) may be inserted into any one of the plurality of open areas (622) through the sixth hole (626b). The ejector (E) may engage any one of the plurality of open areas (622) and may limit the rotation of the first coupling member (621).

[0237] In one embodiment, with the ejector (E) inserted into the sixth hole (626b), the second coupling member (626) can be rotated and separated from the first coupling member (621). Alternatively, with the ejector (E) inserted into the sixth hole (626b), the second coupling member (626) can be rotated and coupled to the first coupling member (621).

[0238] In one embodiment of the present document, the ejector (E) can limit the rotation of the first coupling member (621) through the sixth hole (626b). The electronic device (600) can easily and simply limit the rotation of the first coupling member (621) without including a separate locking structure. A user can easily and simply separate the second coupling member (626) from the first coupling member (621) or replace the second coupling member (626) using the ejector (E) without the intervention of a specialist or specialized equipment.

[0239] FIG. 7 is a cross-sectional view of an electronic device (700) according to one embodiment.

[0240] Referring to FIG. 7, an electronic device (700) (e.g., an electronic device (101) of FIG. 1, an electronic device (200) of FIGS. 2a and 2b, an electronic device (300) of FIGS. 3a and 3b, an electronic device (400) of FIGS. 4a, 4b, 4c, 4d and 4e, an electronic device (500) of FIGS. 5a, 5b, 5c, 5d and 5e or an electronic device (600) of FIGS. 6a and 6b) has a housing structure (710) (e.g., a housing (210) of FIGS. 2a and 2b, a housing (310) of FIGS. 3a and 3b, a housing structure (410) of FIGS. 4a, 4b, 4c, 4d and 4e, a housing structure (410) of FIGS. 5a, 5b, 5c, 5d and 5e). It may include a housing structure (510) of 5e or a housing structure (610) of FIGS. 6a and 6b) and a rotation unit (720) (e.g., a wheel key (320) of FIG. 3a, a rotation unit (420) of FIGS. 4a, 4b, 4c, 4d and 4e, a rotation unit (520) of FIGS. 5a, 5b, 5c, 5d and 5e or a rotation unit (620) of FIGS. 6a and 6b).

[0241] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the electronic device (700) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the electronic device (700) unless it is technically clearly impossible.

[0242] In one embodiment, the electronic device (700) may be a wearable device that can be attached to a part of the body, such as a smartwatch. Alternatively, and not limited thereto, the electronic device (700) may be any one of various types of devices, such as a wireless communication device, a display device, a home appliance, an industrial device, or a computer processing device.

[0243] In one embodiment, the housing structure (710) may form the exterior of the electronic device (700). Alternatively, the housing structure (710) may accommodate, support, and / or protect electrical components of the electronic device (700). Alternatively, the housing structure (710) may be the body or main body of the electronic device (700).

[0244] In one embodiment, the housing structure (710) may include a coupling area (715). The coupling area (715) may be an area to which a rotation unit (720) is coupled. The shape, structure, and size of the coupling area (715) are not limited, and may have a shape surrounding an opening in the center of the housing structure (710). For example, the coupling area (715) may have an annular or ring-shaped shape. Alternatively, the coupling area (715) may have a shape corresponding to the shape of the rotation unit (720).

[0245] In one embodiment, the rotation unit (720) may be rotatably fastened to the coupling area (715). The rotation unit (720) may be rotated clockwise and / or counterclockwise with respect to a front view of the electronic device (700).

[0246] In one embodiment, a guide member (709) may be provided between the housing structure (710) and the rotation unit (720). The guide member (709) may support the rotation unit (720) so that it is rotatably fastened to the housing structure (710). Alternatively, the guide member (709) may support the rotation unit (720) so that the rotation unit (720) does not come off during rotational driving, or may guide the rotation of the rotation unit (720).

[0247] In one embodiment, the rotation unit (720) may include a first coupling member (721) and a second coupling member (726). For example, the first coupling member (721) may be a base wheel or a drive wheel. For example, the second coupling member (726) may be a changeable wheel or a decoration wheel.

[0248] In one embodiment, the first coupling member (721) may be positioned opposite the coupling area (715). The first coupling member (721) may be fixed or coupled in a rotatably manner with respect to the housing structure (710).

[0249] In one embodiment, the second coupling member (726) can be selectively and removably coupled to the first coupling member (721). The second coupling member (726) can be coupled to the first coupling member (721) in an opposite direction to the housing structure (710) with respect to the first coupling member (721). The second coupling member (726) can be visually exposed to the exterior of the electronic device (700).

[0250] For example, a first coupling member (721) may be coupled to a coupling region (715) so as to be rotatable relative to the coupling region (715). A second coupling member (726) may be coupled to the first coupling member (721) and rotate together with the first coupling member (721). Additionally, the second coupling member (726) may be optionally separable from the first coupling member (721).

[0251] In one embodiment of the present document, the rotation unit (720) can separate the second coupling member (726) from the electronic device (700) or connect the second coupling member (726) to the electronic device (700) by selectively separating the second coupling member (726). The second coupling member (726) can be easily and simply replaced as needed. For example, if replacement of properties such as shape, color, structure, material, or texture of the second coupling member (726) is required, the second coupling member (726) can be separated from the first coupling member (721) and replaced with another second coupling member (726).

[0252] In one embodiment of the present document, the electronic device (700) can efficiently replace the rotation unit (720) of the electronic device (700) by maintaining the first rotation unit (720) and replacing only the second coupling member (726).

[0253] In one embodiment, the first coupling member (721) may include a plurality of open areas (722). The plurality of open areas (722) may be arranged along the coupling area (715). The plurality of coupling areas (715) may be arranged at predetermined intervals. For example, with respect to the center of the annular first coupling member (721), the plurality of coupling areas (715) may be arranged at equal intervals of 15 degrees. However, the arrangement of the plurality of coupling areas (715) is not limited thereto, and may be formed at various intervals (e.g., 5 degrees or 10 degrees), or at least a portion of the plurality of coupling areas (715) may be formed at irregular intervals.

[0254] In one embodiment of the present document, the electronic device (700) can be replaced by selectively separating the second coupling member (726) among the rotation unit (720), thereby preventing exposure of other components disposed between the first coupling member (721) and the housing structure (710), and reducing or preventing the risk of loss or damage of components of the electronic device (700).

[0255] In one embodiment of the present document, the electronic device (700) can easily separate only the second coupling member (726) while the first coupling member (721) remains coupled to the housing structure (710), and the second coupling member (726) can be maintained or selectively replaced, so that a part of the rotation unit (720) of the electronic device (700) can be easily and efficiently replaced.

[0256] For example, if the appearance of the electronic device (700) needs to be replaced according to the user's needs or preferences, the electronic device (700) according to one embodiment of the present document can easily separate the second coupling member (726) from the electronic device (700), and maintain or replace the second coupling member (726).

[0257] In one embodiment of the present document, the electronic device (700) can provide various usability to the user by easily replacing the second coupling member (726). Furthermore, the electronic device (700) can provide convenience to the user because it does not require separate specialized equipment or assistance from specialized personnel to replace the second coupling member (726).

[0258] In one embodiment, the first coupling member (721) and the second coupling member (726) may be connected by a coupling member (725). The coupling member (725) may be provided between the first coupling member (721) and the second coupling member (726). The coupling member (725) may be formed of various structures and materials, and may be, for example, an adhesive material, a protruding structure, or a bracket structure.

[0259] In one embodiment, the connecting member (725) may be provided between the upper portion (e.g., +Z direction) of the first connecting member (721) and the lower portion (e.g., -Z direction) of the second connecting member (726). However, the arrangement and shape of the connecting member (725) are not limited thereto, and the connecting member (725) may be arranged in a side direction (e.g., circumferential direction) where the first connecting member (721) and the second connecting member (726) face each other. Alternatively, the connecting member (725) may be formed over at least a portion of a plurality of surfaces where the first connecting member (721) and the second connecting member (726) face each other.

[0260] In one embodiment of the present document, the connecting member (725) can easily and simply connect the first connecting member (721) and the second connecting member (726). In addition, since the first connecting member (721) and the second connecting member (726) do not require separate fastening structures, the connecting member (725) can provide an advantage in reducing the manufacturing difficulty of the first connecting member (721) and the second connecting member (726).

[0261] FIG. 8 is a cross-sectional view of an electronic device (800) according to one embodiment.

It may include a housing structure (510) of 5e or a housing structure (610) of FIGS. 6a and 6b) and a rotation unit (820) (e.g., a wheel key (320) of FIG. 3a, a rotation unit (420) of FIGS. 4a, 4b, 4c, 4d and 4e, a rotation unit (520) of FIGS. 5a, 5b, 5c, 5d and 5e or a rotation unit (620) of FIGS. 6a and 6b).

[0263] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that some components and structures of the electronic device (800) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the embodiments described above may be combined in the electronic device (800) unless it is technically clearly impossible.

[0264] In one embodiment, the electronic device (800) may be a wearable device that can be attached to a part of the body, such as a smartwatch. Alternatively, and not limited thereto, the electronic device (800) may be any one of various types of devices, such as a wireless communication device, a display device, a home appliance, an industrial device, or a computer processing device.

[0265] In one embodiment, the housing structure (810) may form the exterior of the electronic device (800). Alternatively, the housing structure (810) may accommodate, support, and / or protect electrical components of the electronic device (800). Alternatively, the housing structure (810) may be the body or main body of the electronic device (800).

[0266] In one embodiment, the housing structure (810) may include a coupling area (815). The coupling area (815) may be an area to which a rotation unit (820) is coupled. The shape, structure, and size of the coupling area (815) are not limited, and may have a shape surrounding an opening in the center of the housing structure (810). For example, the coupling area (815) may have an annular or ring-shaped shape. Alternatively, the coupling area (815) may have a shape corresponding to the shape of the rotation unit (820).

[0267] In one embodiment, the rotation unit (820) may be rotatably fastened to the coupling area (815). The rotation unit (820) may be rotated clockwise and / or counterclockwise with respect to a front view of the electronic device (800).

[0268] In one embodiment, a guide member (809) may be provided between the housing structure (810) and the rotation unit (820). The guide member (809) may support the rotation unit (820) so that it is rotatably fastened to the housing structure (810). Alternatively, the guide member (809) may support the rotation unit (820) so that the rotation unit (820) does not come off during rotational driving, or may guide the rotation of the rotation unit (820).

[0269] In one embodiment, the rotation unit (820) may include a first coupling member (821) and a second coupling member (826). For example, the first coupling member (821) may be a base wheel or a drive wheel. For example, the second coupling member (826) may be a changeable wheel or a decoration wheel.

[0270] In one embodiment, the first coupling member (821) may be positioned opposite the coupling area (815). The first coupling member (821) may be fixed or coupled in a rotatably manner with respect to the housing structure (810).

[0271] In one embodiment, the second coupling member (826) can be selectively and removably coupled to the first coupling member (821). The second coupling member (826) can be coupled to the first coupling member (821) in an opposite direction to the housing structure (810) with respect to the first coupling member (821). The second coupling member (826) can be visually exposed to the exterior of the electronic device (800).

[0272] For example, a first coupling member (821) may be coupled to a coupling region (815) so as to be rotatable relative to the coupling region (815). A second coupling member (826) may be coupled to the first coupling member (821) so as to be rotatable together with the first coupling member (821). Additionally, the second coupling member (826) may be optionally separable from the first coupling member (821).

[0273] In one embodiment of the present document, the rotation unit (820) can separate the second coupling member (826) from the electronic device (800) or attach the second coupling member (826) to the electronic device (800) by selectively separating the second coupling member (826). The second coupling member (826) can be easily and simply replaced as needed. For example, if replacement of properties such as shape, color, structure, material, or texture of the second coupling member (826) is required, the second coupling member (826) can be separated from the first coupling member (821) and replaced with another second coupling member (826).

[0274] In one embodiment of the present document, the electronic device (800) can efficiently replace the rotation unit (820) of the electronic device (800) by maintaining the first rotation unit (820) and replacing only the second coupling member (826).

[0275] In one embodiment, the first coupling member (821) may include a plurality of open areas (822). The plurality of open areas (822) may be arranged along the coupling area (815). The plurality of coupling areas (815) may be arranged at predetermined intervals. For example, with respect to the center of the annular first coupling member (821), the plurality of coupling areas (815) may be arranged at equal intervals of 15 degrees. However, the arrangement of the plurality of coupling areas (815) is not limited thereto, and may be formed at various intervals (e.g., 5 degrees or 10 degrees), or at least a portion of the plurality of coupling areas (815) may be formed at irregular intervals.

[0276] In one embodiment of the present document, the electronic device (800) can be replaced by selectively separating the second coupling member (826) among the rotation units (820), thereby preventing exposure of other components disposed between the first coupling member (821) and the housing structure (810), and reducing or preventing the risk of loss or damage of components of the electronic device (800).

[0277] In one embodiment of the present document, the electronic device (800) can easily separate only the second coupling member (826) while the first coupling member (821) remains coupled to the housing structure (810), and the second coupling member (826) can be maintained or selectively replaced, so that some components of the rotation unit (820) of the electronic device (800) can be easily and efficiently replaced.

[0278] For example, if the appearance of the electronic device (800) needs to be replaced according to the user's needs or preferences, the electronic device (800) according to one embodiment of the present document can easily separate the second coupling member (826) from the electronic device (800), and maintain or replace the second coupling member (826).

[0279] In one embodiment of the present document, the electronic device (800) can provide various usability to the user by easily replacing the second coupling member (826). In addition, the electronic device (800) can provide convenience to the user because it does not require separate specialized equipment or assistance from specialized personnel to replace the second coupling member (826).

[0280] In one embodiment, the first coupling member (821) may include a fastening groove (821a). The second coupling member (826) may include a hook area (826a). In one embodiment, the first coupling member (821) and the second coupling member (826) may be connected by the fastening groove (821a) and the hook area (826a).

[0281] For example, the hook region (826a) can be inserted into the fastening groove (821a). The fastening groove (821a) can be formed along the outer circumference of the first coupling member (821). The hook region (826a) can be an area extending from the second coupling member (826) to the fastening groove (821a) so as to be inserted into at least a portion of the fastening groove (821a).

[0282] In one embodiment, the hook region (826a) may be formed with an offset (826b) on the lower surface. The offset (826b) of the hook region (826a) may assist in the smooth and soft insertion of the second coupling member (826) into the first coupling member (821).

[0283] For example, the offset (826b) may be formed in an area facing the first coupling member (821) from the hook area (826a). The offset (826b) is formed to be inclined toward the first coupling member (821), so that when the first coupling member (821) and the second coupling member (826) are coupled, the offset (826b) may come into contact with the first coupling member (821) and potentially pressurize and deform the hook area (826a). The first coupling member (821) and the second coupling member (826) may be smoothly and softly coupled by the offset (826b).

[0284] In one embodiment of the present document, the fastening groove (821a) and the hook area (826a) can stably fasten the first fastening member (821) and the second fastening member (826).

[0287] Referring to FIGS. 9A and 9B, an electronic device (900) (e.g., an electronic device (101) of FIG. 1, an electronic device (200) of FIGS. 2A and 2B, an electronic device (300) of FIGS. 3A and 3B, an electronic device (400) of FIGS. 4A, 4B, 4C, 4D and 4E, an electronic device (500) of FIGS. 5A, 5B, 5C, 5D and 5E or an electronic device (600) of FIGS. 6A and 6B) has a housing structure (910) (e.g., a housing (210) of FIGS. 2A and 2B, a housing (310) of FIGS. 3A and 3B, a housing structure (410) of FIGS. 4A, 4B, 4C, 4D and 4E, and FIGS. 5A, 5B, 5C, 5D and 5E). 5d and 5e or the housing structure (610) of FIGS. 6a and 6b) and a rotation unit (920) (e.g., wheel key (320) of FIG. 3a, rotation unit (420) of FIGS. 4a, 4b, 4c, 4d and 4e, rotation unit (520) of FIGS. 5a, 5b, 5c, 5d and 5e or rotation unit (620) of FIGS. 6a and 6b).

Alternatively, the housing structure (910) may be the body or main body of the electronic device (900).

[0291] In one embodiment, the housing structure (910) may include a coupling area (915). The coupling area (915) may be an area to which a rotation unit (920) is coupled. The shape, structure, and size of the coupling area (915) are not limited, and may have a shape surrounding an opening in the center of the housing structure (910). For example, the coupling area (915) may have an annular or ring-shaped shape. Alternatively, the coupling area (915) may have a shape corresponding to the shape of the rotation unit (920).

[0292] In one embodiment, the rotation unit (920) may be rotatably fastened to the coupling area (915). The rotation unit (920) may be rotated clockwise and / or counterclockwise with respect to a front view of the electronic device (900).

[0293] In one embodiment, a guide member (909) may be provided between the housing structure (910) and the rotation unit (920). The guide member (909) may support the rotation unit (920) so that it is rotatably fastened to the housing structure (910). Alternatively, the guide member (909) may support the rotation unit (920) so that the rotation unit (920) does not come off during rotational driving, or may guide the rotation of the rotation unit (920).

[0294] In one embodiment, the rotation unit (920) may include a first coupling member (921) and a second coupling member (926). For example, the first coupling member (921) may be a base wheel or a drive wheel. For example, the second coupling member (926) may be a changeable wheel or a decoration wheel.

[0295] In one embodiment, the first coupling member (921) may be positioned opposite the coupling area (915). The first coupling member (921) may be fixed or coupled in a rotatably manner with respect to the housing structure (910).

[0296] In one embodiment, the second coupling member (926) can be selectively and removably coupled to the first coupling member (921). The second coupling member (926) can be coupled to the first coupling member (921) in an opposite direction to the housing structure (910) with respect to the first coupling member (921). The second coupling member (926) can be visually exposed to the exterior of the electronic device (900).

[0297] For example, a first coupling member (921) may be coupled to a coupling region (915) so as to be rotatable relative to the coupling region (915). A second coupling member (926) may be coupled to the first coupling member (921) and rotate together with the first coupling member (921). Additionally, the second coupling member (926) may be optionally separable from the first coupling member (921).

[0298] In one embodiment of the present document, the rotation unit (920) can separate the second coupling member (926) from the electronic device (900) or attach the second coupling member (926) to the electronic device (900) by selectively separating the second coupling member (926). The second coupling member (926) can be easily and simply replaced as needed. For example, if replacement of properties such as shape, color, structure, material, or texture of the second coupling member (926) is required, the second coupling member (926) can be separated from the first coupling member (921) and replaced with another second coupling member (926).

[0299] In one embodiment of the present document, the electronic device (900) can easily separate only the second coupling member (926) while the first coupling member (921) remains coupled to the housing structure (910), and by maintaining or selectively replacing the second coupling member (926), a part of the rotation unit (920) of the electronic device (900) can be easily and efficiently replaced.

[0300] For example, if the appearance of the electronic device (900) needs to be replaced according to the user's needs or preferences, the electronic device (900) according to one embodiment of the present document can easily separate the second coupling member (926) from the electronic device (900), and maintain or replace the second coupling member (926).

[0301] In one embodiment of the present document, the electronic device (900) can provide various usability to the user by easily replacing the second coupling member (926). Furthermore, the electronic device (900) can provide convenience to the user because it does not require separate specialized equipment or assistance from specialized personnel to replace the second coupling member (926).

[0302] In one embodiment, the first coupling member (921) may include a plurality of open areas (922). The plurality of open areas (922) may be arranged along the coupling area (915). The plurality of coupling areas (915) may be arranged at predetermined intervals. For example, with respect to the center of the annular first coupling member (921), the plurality of coupling areas (915) may be arranged at equal intervals of 15 degrees. However, the arrangement of the plurality of coupling areas (915) is not limited thereto, and may be formed at various intervals (e.g., 5 degrees or 10 degrees), or at least a portion of the plurality of coupling areas (915) may be formed at irregular intervals.

[0303] In one embodiment of the present document, the electronic device (900) can be replaced by selectively separating the second coupling member (926) among the rotation units (920), thereby preventing exposure of other components disposed between the first coupling member (921) and the housing structure (910), and reducing or preventing the risk of loss or damage of components of the electronic device (900).

[0304] In one embodiment, the locking unit (940) can be configured to be insertable into at least one of the plurality of open areas (922). The locking unit (940) can selectively limit the rotation of the first coupling member (921). When the locking unit (940) limits the rotation of the first coupling member (921), the second coupling member (926) can be made rotatable independently of the first coupling member (921). By allowing the second coupling member (926) to rotate independently of the first coupling member (921), the second coupling member (926) can be separated from the first coupling member (921) or coupled to the first coupling member (921).

[0305] In one embodiment, the locking unit (940) may include a locking pin (941) for limiting rotation of the first coupling member (921). The housing structure (910) may include a first hole (911a). The first hole (911a) may be formed in the first surface (911). The first hole (911a) may be arranged to face any one of the plurality of open areas (922) in the coupling area (915).

[0306] In one embodiment, the locking pin (941) can protrude from the first hole (911a) in a pressurized state and move into one of the plurality of open areas (922). The locking pin (941) can be inserted into one of the open areas (922) in a pressurized state to engage with the first coupling member (921), and the locking pin (941) can limit rotation of the first coupling member (921).

[0307] In one embodiment, the housing structure (910) may include a third hole (913a). The third hole (913a) may be provided on the third surface (913) of the housing structure (910). The third hole (913a) may be a hole in which a pressure button (919) is positioned. The third hole (913a) may be positioned opposite the pressure surface (941b).

[0308] In one embodiment, the electronic device (900) may further include a press button (919). The press button (919) may be positioned in the third hole (913a) so as to be visually exposed from the outside of the housing structure (910). The press button (919) may move inwardly of the housing structure (910) when pressed by an external force.

[0309] In one embodiment, the locking pin (941) may include a protruding region (941a) and a pressing surface (941b). The protruding region (941a) may be an area that is inserted into one of the plurality of open regions (922) when pressed.

[0310] In one embodiment, the pressurized surface (941b) may be one surface pressed by the pressurized button (919) of the locking pin (941). The protruding region (941a) and the pressurized surface (941b) may be provided at opposite positions on the locking pin (941).

[0311] For example, when the pressurized surface (941b) is pressed by the pressurized button (919), the protruding area (941a) can protrude from the first hole (911a) and be inserted into one of the plurality of open areas (922).

[0312] For example, in a state where the pressurized surface (941b) is not pressed by the pressurized button (919) (e.g., initial state), the protruding area (941a) of the locking pin (941) may be positioned outside the open area (922) or spaced apart from the open area (922). Accordingly, the locking pin (941) may not restrict the rotation of the first coupling member (921).

[0313] For example, when the pressurized surface (941b) is pressed by the pressurized button (919), the locking pin (941) rises and the protruding region (941a) can be inserted into one of the open regions (922). Accordingly, the locking pin (941) can limit the rotation of the first coupling member (921).

[0314] In one embodiment, the locking unit (940) may further include at least a portion of the locking housing (943) and the elastic body (945).

[0315] In one embodiment, the elastic body (945) can transmit an elastic force to the locking pin (941) and the pressure button (919) so that the locking pin (941) returns to its position before being pressed (e.g., its initial position). For example, when the locking pin (941) is pressed by the pressure button (919), the elastic body (945) can be compressed. When the external force pressing the pressure button (919) is reduced or removed, the locking pin (941) and the pressure button (919) can return to their initial positions by the elastic force of the elastic body (945).

[0316] In one embodiment, the locking housing (943) may form the exterior of the locking unit (940). Alternatively, the locking housing (943) may accommodate or support other configurations of the locking unit (940). The locking housing (943) accommodates the locking unit (940) and may be disposed inside the housing structure (910).

[0317] In one embodiment of the present document, the electronic device (900) can easily and simply limit the rotation of the first coupling member (921) through the pressure button (919). A user can easily and simply separate the second coupling member (926) from the first coupling member (921) or replace the second coupling member (926) by pressing the pressure button (919) without the intervention of a specialist or specialized equipment.

[0318] An electronic device (400; 500; 600) according to one embodiment may include a housing structure (410; 510; 610) including an annular coupling area (415; 515; 615) and a rotation unit (420; 520; 620) fastened to the coupling area (415; 515; 615). In one embodiment, the rotation unit (420; 520; 620) includes a first coupling member (421; 521; 621) fastened to the coupling area (415; 515; 615) so as to be rotatable relative to the coupling area (415; 515; 615); And it may include a second coupling member (426; 526; 626) coupled to and rotating with the first coupling member (421; 521; 621) and optionally separable from the first coupling member (421; 521; 621).

[0319] In one embodiment, the second coupling member (426; 526; 626) is screw-coupled to the first coupling member (421; 521; 621) and can be rotated independently of the first coupling member (421; 521; 621) while the rotation of the first coupling member (421; 521; 621) is restricted.

[0320] In one embodiment, the first joining member (421; 521; 621) may include a plurality of open areas (422; 522; 622) arranged along the joining area (415; 515; 615).

[0321] In one embodiment, the electronic device (400; 500; 600) may further include a detent structure (430; 530; 630) positioned opposite at least one of the plurality of open areas (422; 522; 622) and providing a detent force with respect to the rotation unit (420; 520; 620).

[0322] In one embodiment, the detent structure (430; 530; 630) may include a movable member (431; 531; 631) that is inserted or de-inserted into one of the plurality of open areas (422; 522; 622) and that impedes rotation of the first engaging member (421; 521; 621) and a spring (432; 532; 632) that supports the movable member (431; 531; 631).

[0323] In one embodiment, the electronic device (400; 500) may further include a locking unit (440; 540) configured to be insertable into at least one of the plurality of open areas (422; 522) to selectively limit rotation of the first coupling member (421; 521).

[0324] In one embodiment, the housing structure (410; 510) may include a first hole (411a; 511a) positioned opposite one of the plurality of open areas (422; 522) in the joining area (415; 515).
