Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms of “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

As used herein, each of such phrases as "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", may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as "1^st" and "2^nd," or "first" and "second" may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if a component (e.g., a first component) is referred to, with or without the term "operatively" or "communicatively", as "coupled with", "coupled to", "connected with", or "connected to" another component (e.g., a second component), it means that the component may be coupled with the other component directly (e.g., by wire), wirelessly, or via a third component.

As used in connection with embodiments of the disclosure, the term "module" may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, "logic", "logic block", "part", or "circuitry". A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment the module may be implemented in a form of an application-specific integrated circuit (ASIC).

Embodiments as set forth herein may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., the electronic device 101). For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium and execute it. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. 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, the term "non-transitory" simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.

According to an embodiment, a method according to embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read-only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore^TM), or between two user devices (e.g., smartphones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.

Referring to FIGS. 4A and 4B, the accessory device 400 according to various embodiments may include at least some of the housing 410, the axis member 430, the locking member 460, and the elastic member 470.

Hereinafter, descriptions repeated with the foregoing will be omitted for brevity. It should be understood that some components and structures of the accessory device 400 may be substituted, added, or omitted within a scope easily understood by those skilled in the art with reference to the following drawings and descriptions. In addition, the accessory device 400 may include at least one component or feature of the above-described embodiments, unless technically impossible.

In an embodiment, the accessory device 400 (e.g., the engagement members 250 and 260 of FIGS. 2A and 2B or the engagement members 381 and 382 of FIGS. 3A and 3B) may be detachably connected to at least a portion of a component of an electronic device (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). Alternatively, the accessory device 400 may be a component of the electronic device. Alternatively, the accessory device 400 may be physically and/or electrically connected to the electronic device or another connection device.

For example, the accessory device 400 may assist a user in wearing the electronic device. Alternatively, the accessory device 400 may complement the performance of the electronic device and/or improve its usability. The accessory device 400 may also serve as a fashion accessory.

The accessory device 400 as illustrated in the drawings merely represents an example in which the accessory device 400 is connected to the main body of an electronic device when the electronic device is a smartwatch. However, the structure and role of the accessory device 400 according to various embodiments of the disclosure are not limited thereto.

In an embodiment, the housing 410 may be the body of the accessory device 400 that is connected to an electronic device. The housing 410 may accommodate some components of the accessory device 400 therein. One end of the housing 410 may be connected to a strap 425.

In an embodiment, the strap 425 may be worn on a part of the user's body to support the electronic device on the user. For example, when the electronic device is the main body of a smartwatch, the strap 425 may be worn on the user's wrist. However, the strap 425 is not limited thereto and may be implemented in various forms. For example, the strap 425 may be replaced with a cable, a plate-shaped member, a three-dimensional structure, or an external electronic or communication device. Alternatively, the strap 425 may accommodate electronic components (e.g., a battery, a communication module, or an input/output module) and may be replaced with an auxiliary device that is functionally linked to the main body of the electronic device.

In an embodiment, the accessory device 400 may include an outer cover 427 that surrounds at least a portion of an outer circumferential surface of the housing 410. The outer cover 427 may connect the housing 410 and the strap 425. The outer cover 427 may be integrally formed with the strap 425 or may be separately formed and fixed to the strap 425.

In an embodiment, the outer cover 427 may be formed of leather, artificial leather, fabric, thermoplastic polyurethane (TPU), or a rubber mold. The outer cover 427 may cover the entire outer circumferential surface or most of the outer circumferential surface of the strap 425, in addition to the housing 410.

In an embodiment, the housing 410 may include a first housing region 411 and a second housing region 412. The first housing region 411 and the second housing region 412 may be implemented as an integral body or may be separately formed and joined together.

For example, the first housing region 411 may be an upper housing region facing upward (e.g., in the +Z direction) or an inner housing region facing inward with respect to the user's body of the electronic device. The second housing region 412 may be a lower housing region facing downward or an outer housing region facing outward with respect to the user's body.

In an embodiment, the housing 410 may include a receiving groove 415 and a pin hole 417. For example, the receiving groove 415 and the pin hole 417 may be formed between the first housing region 411 and the second housing region 412. The receiving groove 415 and the pin hole 417 may be disposed adjacent to each other along a rotation axis Rx. The pin hole 417 may be formed to extend from the receiving groove 415 to the outside of the housing 410.

In an embodiment, the housing 410 may further include a wing region 420. The wing region 420 may be disposed above an inner center C of the housing 410 (e.g., in the -Z direction). The wing region 420 may be integrally formed with the housing 410 and protrude outward from the housing 410.

For example, the wing region 420 may be formed in the first housing region 411 and, compared to other portions of the first housing region 411, may have a shape that extends and protrudes further upward (e.g., in the -Z direction).

In an embodiment, the wing region 420 may limit the movement range of the electronic device and the accessory device 400 while the accessory device 400 is worn by the user and prevent the electronic device and the accessory device 400 from freely rotating or moving on the user's body.

For example, the wing region 420 may protrude toward the user and contact the user's body. The wing region 420 may limit movement of the electronic device and the accessory device 400 by a frictional force acting on a contact portion with the user.

In various embodiments of the disclosure, the wing region 420 may improve the wearing stability of the accessory device 400. In addition, the wing region 420 may limit the position at which the electronic device is worn and the range of free movement of the electronic device and assist the electronic device in implementing its functions (e.g., a display function, a surrounding environment sensing function, or a user state sensing function).

In an embodiment, the axis member 430 may be rotatably disposed in the receiving groove 415 in a first rotation direction R1 or a second rotation direction R2 opposite to the first rotation direction R1 about the rotation axis Rx. The axis member 430 may have a pillar or cylinder-shaped structure extending along the rotation axis Rx.

In an embodiment, the axis member 430 may be connected to a lever 450 extending outside the housing 410 and may rotate about the rotation axis Rx to move the locking member 460. The axis member 430 may include a through hole 431 and a first inclined surface 435.

In an embodiment, the first inclined surface 435 may be a surface of the axis member 430 that faces the inner center C of the housing 410. Alternatively, the first inclined surface 435 may be a surface of the axis member 430 that faces the locking member 460.

In an embodiment, the first inclined surface 435 may be inclined at a predetermined angle with respect to the rotation axis Rx. For example, the first inclined surface 435 may be inclined at a predetermined angle in a direction (e.g., in a Y-axis direction) horizontal to the rotation axis Rx, based on a plane (e.g., an X-Z plane) perpendicular to the rotation axis Rx. For example, the predetermined angle may be any angle within a range of 20 degrees to 70 degrees, 30 degrees to 60 degrees, or 40 degrees to 50 degrees.

In an embodiment, the lever 450 may be connected to the axis member 430 and protrude outward from the housing 410. The lever 450 may be integrally formed with the axis member 430 or may be separately formed and coupled to the axis member 430. When an external force is applied (e.g., by a user) to the lever 450, the lever 450 may rotate about the rotation axis Rx. The lever 450 may rotate to cause the locking member 460 to rotate. The rotation axis Rx of the lever 450 may be aligned with the rotation axis Rx of the axis member 430.

In an embodiment, the locking member 460 may be movably disposed in the receiving groove 415 along the rotation axis Rx in a first direction D1 (e.g., a +Y direction) toward the inner center C of the housing 410 or in a second direction D2 (e.g., a -Y direction) opposite to the first direction D1. The locking member 460 may include a pin region 461 and a second inclined surface 465.

In an embodiment, the locking member 460 may move in response to the rotation of the axis member 430. As the locking member 460 moves, the pin region 461 may move from inside to outside the housing 410 or from outside to inside the housing 410.

In an embodiment, the pin region 461 may be disposed to penetrate the through hole 431 and the pin hole 417. The pin region 461 may selectively fix the accessory device 400 to the electronic device or to an external connection device.

For example, the pin region 461 may be disposed outside the housing 410 and inserted into a pin groove (not shown) of the electronic device, thereby fixing the accessory device 400 to the electronic device. In addition, the pin region 461 may move into the housing 410 and be separated from the pin groove (not shown) of the electronic device, thereby releasing the accessory device 400 from the electronic device.

In an embodiment, the second inclined surface 465 may be a surface of the locking member 460 that faces the first inclined surface 435. Alternatively, the second inclined surface 465 may be a surface of the locking member 460 that faces the outside of the housing 410.

In an embodiment, the second inclined surface 465 may be inclined at a predetermined angle with respect to the rotation axis Rx. For example, the second inclined surface 465 may be inclined at the same or a similar predetermined angle as the first inclined surface 435. Alternatively, the second inclined surface 465 may be a curved surface having a predetermined curvature in at least a partial region.

In an embodiment, the second inclined surface 465 may be pressed by the first inclined surface 435. The second inclined surface 465 may engage with the first inclined surface 435 and may be pressed in response to the rotation of the first inclined surface 435. As the second inclined surface 465 is pressed, the locking member 460 may move.

In an embodiment, the elastic member 470 may be disposed between the locking member 460 and the receiving groove 415. One end of the elastic member 470 may contact the locking member 460, and the other end of the elastic member 470 may be disposed to contact the receiving groove 415. For example, one end of the elastic member 470 may contact a surface of the locking member 460 opposite to the second inclined surface 465.

In an embodiment, the elastic member 470 may be compressed when the locking member 460 moves in the first direction D1. In addition, the elastic member 470 may be tensioned when the locking member 460 moves in the second direction D2. The elastic member 470 may be compressed and may apply pressure to the locking member 460 in the second direction D2. When a force pressing the locking member 460 in the first direction D1 is removed, the elastic restoring force of the elastic member 470 may move the locking member 460 in the second direction D2. The interlocking structure of the axis member 430 and the locking member 460 according to an embodiment of the disclosure will be described with reference to FIGS. 5A and 5B.

In an embodiment, the housing 410 may further include an auxiliary receiving groove 416 and an auxiliary pin hole 418. The auxiliary receiving groove 416 may be arranged adjacent to the receiving groove 415 along the rotation axis Rx and, for example, may be disposed in a direction opposite to the pin hole 417 from the receiving groove 415. The auxiliary pin hole 418 may be arranged adjacent to the auxiliary receiving groove 416 along the rotation axis Rx and, for example, may be disposed in a direction opposite to the receiving groove 415 from the auxiliary receiving groove 416.

In an embodiment, the auxiliary pin hole 418 may be formed to penetrate from the auxiliary receiving groove 416 to the outside of the housing 410. For example, the pin hole 417 may be formed on one side surface (e.g., a surface in the -Y direction) of the housing 410, and the auxiliary pin hole 418 may be formed on another side surface (e.g., a surface in the +Y direction) of the housing 410.

In an embodiment, the accessory device 400 may further include an auxiliary axis member 480. The auxiliary axis member 480 may be rotatably disposed in the auxiliary receiving groove 416 in a first rotation direction R1 or a second rotation direction R2 about the rotation axis Rx. The auxiliary axis member 480 may include an auxiliary pin region 487. The auxiliary pin region 487 may extend along the rotation axis Rx and may be disposed to penetrate the auxiliary pin hole 418.

In an embodiment, the lever 450 may be simultaneously connected to the axis member 430 and the auxiliary axis member 480. The lever 450 may include a first connection region 451, a second connection region 452, and a pressing region 455. The lever 450 may have a shape extending in the direction of the rotation axis Rx across the wing region 420.

In an embodiment, the first connection region 451 may face one side surface (e.g., a surface in the -Y direction) of the wing region 420 and may be connected to the axis member 430. The second connection region 452 may face another side surface (e.g., a surface in the +Y direction) opposite to the side surface of the wing region 420 and may be connected to the auxiliary axis member 480. For example, the first connection region 451 may be a connection pillar that connects the axis member 430 and one end of the pressing region 455 of the lever 450, and the second connection region 452 may be a connection pillar that connects the auxiliary axis member 480 and the other end of the pressing region 455 of the lever 450.

In an embodiment, the pressing region 455 may extend from the first connection region 451 to the second connection region 452 across the wing region 420. The pressing region 455 may be a region that is pressed by an external force. When the pressing region 455 is pressed, the lever 450 may rotate along the rotation axis Rx. By having a shape extending along the rotation axis Rx, the pressing region 455 may allow the user to easily and conveniently operate the lever 450 without additional equipment or assistance from an expert.

FIG. 5A is an internal perspective view of the accessory device 400 according to an embodiment of the disclosure.

FIG. 5B is an internal perspective view of the accessory device 400 according to an embodiment of the disclosure. Specifically, FIGS. 5A and 5B are internal perspective views illustrating a state in which a portion of the outer cover 427 and the first housing region 411 of the housing 410 are omitted.

Referring to FIGS. 5A and 5B, the accessory device 400 according to various embodiments of the disclosure may move the pin region 461 of the locking member 460 in response to the movement of the lever 450.

Hereinafter, descriptions repeated with the foregoing will be omitted for brevity. It should be understood that some components and structures of the accessory device 400 may be substituted, added, or omitted within a scope easily understood by those skilled in the art with reference to the following drawings and descriptions. In addition, the accessory device 400 may include at least one component or feature of the above-described embodiments, unless technically impossible.

In an embodiment, when the lever 450 rotates from the state of FIG. 5A to the state of FIG. 5B, the pin region 461 of the locking member 460 may move into the housing 410. For example, a first rotation direction (e.g., the first rotation direction R1 in FIG. 4A) may be a direction in which the lever 450 moves closer to the strap 425, and a second rotation direction (e.g., the second rotation direction R2 in FIG. 4A) may be a direction in which the lever 450 moves farther from the strap 425.

In an embodiment, when the lever 450 is pressed and rotates in the first rotation direction R1, the axis member 430, interlocking with the lever 450, may rotate in the first rotation direction R1. When the axis member 430 rotates in the first rotation direction R1, the first inclined surface 435 may press the second inclined surface 465 in a first direction (e.g., the first direction D1 in FIG. 4B). When the second inclined surface 465 is pressed by the first inclined surface 435, the locking member 460 may move in the first direction D1.

In an embodiment, when the locking member 460 moves in the first direction D1, the pin region 461 may also move in the first direction D1 and may move into the housing 410. In addition, when the locking member 460 moves in the first direction D1, the elastic member 470 may be pressed and compressed. The pin region 461 may move into the housing 410 and be separated from a pin groove (not shown) of the electronic device, thereby releasing the accessory device 400 from the electronic device.

In an embodiment of the disclosure, the lever 450 may release the fixation of the accessory device 400 by rotating in a direction toward the strap 425. Because the user operates the lever 450 in the same direction as pulling the strap 425, the operation may be more intuitive and allow easy release of the fixation of the accessory device 400.

In an embodiment, when the lever 450 rotates from the state of FIG. 5B to the state of FIG. 5A, the pin region 461 of the locking member 460 may move to the outside of the housing 410. For example, when an external force pressing the lever 450 is reduced or removed, the elastic restoring force of the elastic member 470 may move the locking member 460 in a second direction (e.g., the second direction D2 of FIG. 4B).

In an embodiment, when the locking member 460 moves in the second direction D2, the pin region 461 may also move in the second direction D2 and move to the outside of the housing 410. Upon moving to the outside of the housing 410, the pin region 461 may be inserted into a pin groove (not shown) of the electronic device, thereby fixing the accessory device 400 to the electronic device.

In an embodiment, when the locking member 460 moves in the second direction D2, the second inclined surface 465 may press the first inclined surface 435 in the second direction D2. When the first inclined surface 435 is pressed in the second direction D2, the axis member 430 may rotate in the second rotation direction R2. The lever 450, interlocking with the axis member 430, may rotate in the second rotation direction R2 and move farther from the strap 425.

In an embodiment of the disclosure, the user may connect or disconnect the accessory device 400 to or from an electronic device by holding the strap 425 and pressing the lever 450 toward a position adjacent to the strap 425. Since the user may press the lever 450 in the direction in which the strap 425 is held, the user may, for example, hold both the strap 425 and the lever 450 with one hand, thereby easily securing the accessory device 400 to the electronic device.

In an embodiment of the disclosure, the accessory device 400 may secure spatial efficiency of its components through the structure and arrangement of the components of the accessory device 400 and reduce the volume and weight of the accessory device 400. By doing so, the accessory device 400 may provide improved wearability, simplify manufacturing, and secure economic feasibility and efficiency in manufacturing. In addition, due to the spatial efficiency, a space for the pressing region 455 of the lever 450 may be secured, and the lever 450 may have a shape extending along the rotation axis Rx.

In addition, in an embodiment of the disclosure, the accessory device 400 may include the lever 450 having a shape that allows the user to easily and conveniently operate the lever 450 without additional equipment or assistance from an expert, thereby enabling the accessory device 400 to be fixed to or released from the electronic device with ease and providing convenience to the user.

FIG. 6A is a perspective view of an accessory device 500 according to an embodiment of the disclosure.

FIG. 6B is an exploded perspective view of a portion of the accessory device 500 according to an embodiment of the disclosure. Specifically, FIG. 6B is an exploded perspective view illustrating an axis member 530, a locking member 560, and an elastic member 570, which are disposed inside a housing 510.

Referring to FIGS. 6A and 6B, the accessory device 500 according to various embodiments of the disclosure may include at least some of a housing 510, an axis member 530, a locking member 560, and an elastic member 570.

Hereinafter, descriptions repeated with the foregoing will be omitted for brevity. It should be understood that some components and structures of the accessory device 500 may be substituted, added, or omitted within a scope easily understood by those skilled in the art with reference to the following drawings and descriptions. In addition, the accessory device 500 may include at least one component or feature of the above-described embodiments, unless technically impossible.

In an embodiment, the accessory device 500 (e.g., the engagement members 250 and 260 of FIGS. 2A and 2B, the engagement members 381 and 382 of FIGS. 3A and 3B, or the accessory device 400 of FIGS. 4A, 4B, 5A, and 5B) may be detachably connected to at least a portion of a component of an electronic device (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). Alternatively, the accessory device 500 may be a component of the electronic device. Alternatively, the accessory device 500 may be physically and/or electrically connected to the electronic device or another connection device.

For example, the accessory device 500 may assist the user in wearing the electronic device. Alternatively, the accessory device 500 may complement the performance of the electronic device and/or improve the usability of the electronic device. Alternatively, the accessory device 500 may serve as a fashion accessory.

The accessory device 500 illustrated in the drawings merely represents an example in which the accessory device 500 is connected to the main body of an electronic device when the electronic device is the main body of a smartwatch, and the structure and role of the accessory device 500 according to various embodiments of the disclosure are not limited thereto.

In an embodiment, the housing 510 may be the body of the accessory device 500 that is connected to the electronic device. The housing 510 may accommodate at least some components of the accessory device 500 therein. One end of the housing 510 may be connected to a strap 525.

In an embodiment, the strap 525 may be worn on the user's body and may support the electronic device for the user. For example, when the electronic device is the main body of a smartwatch, the strap 525 may be worn on the user's wrist. However, the strap 525 is not limited thereto and may be implemented in various forms. For example, the strap 525 may be replaced with a cable, a plate-shaped member, a three-dimensional structure, or an external electronic or communication device. Alternatively, the strap 525 may be replaced with an auxiliary device that accommodates electronic components (e.g., a battery, a communication module, or an input/output module) and is functionally linked to the main body of the electronic device.

In an embodiment, the accessory device 500 may include an outer cover 527 that surrounds at least a portion of an outer circumferential surface of the housing 510. The outer cover 527 may connect the housing 510 and the strap 525. The outer cover 527 may be integrally formed with the strap 525 or may be formed separately and fixed to the strap 525.

In an embodiment, the outer cover 527 may be formed of leather, synthetic leather, fabric, TPU, or a rubber mold. The outer cover 527 may cover the entire outer circumferential surface or most of the outer circumferential surface of the strap 525, in addition to the housing 510.

In an embodiment, the housing 510 may include a first housing region 511 and a second housing region 512. The first housing region 511 and the second housing region 512 may be implemented as an integral body or may be separately formed and joined together.

For example, the first housing region 511 may be an upper housing region facing upward (e.g., in a +Z direction) or an inner housing region facing inward with respect to the user's body of the electronic device. The second housing region 512 may be a lower housing region facing downward or an outer housing region facing outward with respect to the user's body of the electronic device.

In an embodiment, the housing 510 may include a receiving groove 515 and a pin hole 517. For example, the receiving groove 515 and the pin hole 517 may be disposed between the first housing region 511 and the second housing region 512. The receiving groove 515 and the pin hole 517 may be arranged adjacent to each other along the rotation axis Rx. The pin hole 517 may be formed to penetrate from the receiving groove 515 to the outside of the housing 510.

In an embodiment, the housing 510 may further include a wing region 520. The wing region 520 may be disposed above the inner center C of the housing 510 (e.g., in the -Z direction). The wing region 520 may be integrally formed with the housing 510 and may protrude outward from the housing 510.

For example, the wing region 520 may be formed in the first housing region 511 and, compared to other portions of the first housing region 511, may have a shape that extends and protrudes further upward (e.g., in the -Z direction).

In an embodiment, while the accessory device 500 is worn by the user, the wing region 520 may limit the movement range of the electronic device and the accessory device 500 and prevent the electronic device and the accessory device 500 from freely rotating or moving on the user's body.

For example, the wing region 520 may protrude toward the user and contact the user's body. The wing region 520 may limit movement of the electronic device and the accessory device 500 by a frictional force acting on a contact portion with the user.

In various embodiments of the disclosure, the wing region 520 may improve the stability of wearing the accessory device 500. In addition, the wing region 520 may limit the wearing position and the free movement range of the electronic device and may assist the electronic device in implementing its functions (e.g., a display function, a surrounding environment sensing function, or a user state sensing function).

In an embodiment, the axis member 530 may be rotatably disposed in the receiving groove 515 in the first rotation direction R1 or the second rotation direction R2 opposite to the first rotation direction R1 about the rotation axis Rx. The axis member 530 may be a pillar-shaped or cylinder-shaped structure extending along the rotation axis Rx.

In an embodiment, the axis member 530 may be connected to a lever 550 extending outside the housing 510 and may rotate about the rotation axis Rx to move the locking member 560. The axis member 530 may include a through hole 531 and a first inclined surface 535.

In an embodiment, the through hole 531 may be open along the rotation axis Rx. The through hole 531 may be an opening through which a pin region 561 of the locking member 560 is disposed. The through hole 531 may be arranged coaxially with the pin region 561 of the locking member 560 along the rotation axis Rx.

In an embodiment, the first inclined surface 535 may be a surface of the axis member 530 facing the inner center C of the housing 510. Alternatively, the first inclined surface 535 may be a surface of the axis member 530 facing the locking member 560.

In an embodiment, the first inclined surface 535 may be inclined at a predetermined angle with respect to the rotation axis Rx. For example, the first inclined surface 535 may be inclined at a predetermined angle in a direction (e.g., in a Y-axis direction) horizontal to the rotation axis Rx, based on a plane (e.g., an X-Z plane) perpendicular to the rotation axis Rx. For example, the predetermined angle may be any angle within a range of 20 degrees to 70 degrees, 30 degrees to 60 degrees, or 40 degrees to 50 degrees.

In an embodiment, the lever 550 may be connected to the axis member 530 and may protrude outward from the housing 510. The lever 550 may be integrally formed with the axis member 530 or may be separately formed and coupled to the axis member 530. When an external force is applied (e.g., by a user) to the lever 550, the lever 550 may rotate about the rotation axis Rx. The lever 550 may rotate to cause the locking member 560 to rotate. The rotation axis Rx of the lever 550 may be aligned with the rotation axis Rx of the axis member 530.

In an embodiment, the locking member 560 may be movably disposed in the receiving groove 515 along the rotation axis Rx in the first direction D1 (e.g., toward the inner center C of the housing 510) or in the second direction D2 (e.g., a direction opposite to the first direction D1). The locking member 560 may include a pin region 561 and a second inclined surface 565.

However, the first direction D1 and the second direction D2 described in the disclosure are defined based on the center and the outside of the housing 510 and vary depending on the position of each structure, even within a single drawing. For example, for a structure disposed in the -Y direction with respect to the inner center C of the housing 510, the first direction D1 may be the +Y direction, and the second direction D2 may be the -Y direction. However, for a structure disposed in the +Y direction with respect to the inner center C of the housing 510, the first direction D1 may be the -Y direction, and the second direction D2 may be the +Y direction.

In an embodiment, the locking member 560 may move in response to the rotation of the axis member 530. As the locking member 560 moves, the pin region 561 may move from inside to outside the housing 510 or from outside to inside the housing 510.

In an embodiment, the pin region 561 may be disposed to penetrate the through hole 531 and the pin hole 517. The pin region 561 may selectively fix the accessory device 500 to the electronic device or to an external connection device.

For example, the pin region 561 disposed outside the housing 510 may be inserted into a pin groove (not shown) of the electronic device, thereby fixing the accessory device 500 to the electronic device. In addition, the pin region 561 may move into the housing 510 and be separated from the pin groove (not shown) of the electronic device, thereby releasing the accessory device 500 from the electronic device.

In an embodiment, the second inclined surface 565 may be a surface of the locking member 560 that faces the first inclined surface 535. Alternatively, the second inclined surface 565 may be a surface of the locking member 560 that faces the outside of the housing 510.

In an embodiment, the second inclined surface 565 may be inclined at a predetermined angle with respect to the rotation axis Rx. For example, the second inclined surface 565 may be inclined at the same or a similar predetermined angle as the first inclined surface 535. Alternatively, the second inclined surface 565 may be a curved surface having a predetermined curvature in at least a partial region.

In an embodiment, the second inclined surface 565 may be pressed by the first inclined surface 535. The second inclined surface 565 may engage with the first inclined surface 535 and may be pressed in response to the rotation of the first inclined surface 535. As the second inclined surface 565 is pressed, the locking member 560 may move.

In an embodiment, the accessory device 500 may include a plurality of axis members 530 and a plurality of locking members 560. For example, the plurality of axis members 530 may include a first axis member 530a and a second axis member 530b spaced apart on opposite sides with respect to the inner center C of the housing 510. In addition, for example, the plurality of locking members 560 may include a first locking member 560a facing the first axis member 530a and a second locking member 560b facing the second axis member 530b.

In an embodiment, the housing 510 may include a plurality of pin holes 517. The plurality of pin holes 517 may include a first pin hole 517a and a second pin hole 517b. The plurality of pin holes 517 may be arranged adjacent to the receiving groove 515 along the rotation axis Rx.

In an embodiment, the first pin hole 517a and the second pin hole 517b may be spaced apart from each other and disposed in directions opposite to each other from the receiving groove 515. For example, the first pin hole 517a may be formed on one side surface (e.g., a surface in the -Y direction) of the housing 510, and the second pin hole 517b may be formed on another side surface (e.g., a surface in the +Y direction) of the housing 510. The pin region 561 of the first axis member 530a may be disposed in the first pin hole 517a, and the pin region 561 of the second axis member 530b may be disposed in the second pin hole 517b.

In an embodiment, the lever 550 may be simultaneously connected to the first axis member 530a and the second axis member 530b. The lever 550 may include a first connection region 551, a second connection region 552, and a pressing region 555. The lever 550 may have a shape extending in the direction of the rotation axis Rx across the wing region 520.

In an embodiment, the first connection region 551 may face one side surface (e.g., a surface in the -Y direction) of the wing region 520 and may be connected to the first axis member 530a. The second connection region 552 may face another side surface (e.g., a surface in the +Y direction) of the wing region 520 and may be connected to the second axis member 530b. For example, the first connection region 551 may be a connection pillar that connects the first axis member 530a and one end of the pressing region 555 of the lever 550, and the second connection region 552 may be a connection pillar that connects the second axis member 530b and the other end of the pressing region 555 of the lever 550.

In an embodiment, the pressing region 555 may extend from the first connection region 551 to the second connection region 552 across the wing region 520. The pressing region 555 may be a region that is pressed by an external force. When the pressing region 555 is pressed, the lever 550 may rotate along the rotation axis Rx. By having a shape extending along the rotation axis Rx, the pressing region 555 may enable the user to easily and conveniently operate the lever 550 without additional equipment or assistance from an expert.

In an embodiment, the elastic member 570 may be disposed between the first locking member 560a and the second locking member 560b. One end of the elastic member 570 may contact the first locking member 560a, and the other end of the elastic member 570 may be disposed to contact the second locking member 560b. For example, both ends of the elastic member 570 may contact surfaces of the respective locking members 560 that are opposite to the second inclined surface 565.

In an embodiment, the elastic member 570 may be compressed when at least one of the first locking member 560a and the second locking member 560b moves in the first direction D1. In addition, the elastic member 570 may be tensioned when at least one of the first locking member 560a and the second locking member 560b moves in the second direction D2.

In an embodiment, the elastic member 570, interlocking with the lever 550, may be compressed or tensioned. Since the first locking member 560a and the second locking member 560b are connected by a single lever 550, both locking members may move simultaneously in the first direction D1 toward the inner center C of the housing 510 or in the second direction D2 toward the outside of the housing 510.

In an embodiment, the elastic member 570 may be compressed and may apply pressure to the locking members 560 in the second direction D2. When a force pressing the locking members 560 in the first direction D1 is removed, the elastic restoring force of the elastic member 570 may move the locking members 560 in the second direction D2. The interlocking structure of the axis members 530 and the locking members 560 according to an embodiment of the disclosure will be described with reference to FIGS. 7A and 7B.

FIG. 7A is an internal perspective view of the accessory device 500 according to an embodiment of the disclosure.

FIG. 7B is an internal perspective view of the accessory device 500 according to an embodiment of the disclosure. Specifically, FIGS. 7A and 7B are internal perspective views illustrating a state in which a partial region of the outer cover 527 and the first housing region 511 of the housing 510 are omitted.

Referring to FIGS. 7A and 7B, the accessory device 500 according to various embodiments of the disclosure may move a pin region 561 of a locking member 560 in response to the movement of a lever 550.

Hereinafter, descriptions repeated with the foregoing will be omitted for brevity. It should be understood that some components and structures of the accessory device 500 may be substituted, added, or omitted within a scope easily understood by those skilled in the art with reference to the following drawings and descriptions. In addition, the accessory device 500 may include at least one component or feature of the above-described embodiments, unless such combination is technically impossible.

In an embodiment, when the lever 550 rotates from the state shown in FIG. 7A to the state shown in FIG. 7B, each pin region 561 of the plurality of locking members 560 may move into the housing 510. For example, a first rotation direction (e.g., the first rotation direction R1 in FIG. 6A) may be a direction in which the lever 550 moves closer to the strap 525, and a second rotation direction (e.g., the second rotation direction R2 in FIG. 6A) may be a direction in which the lever 550 moves farther from the strap 525.

In an embodiment, when the lever 550 is pressed to rotate in the first rotation direction R1, the plurality of axis members 530, interlocking with the lever 550, may rotate in the first rotation direction R1. When the plurality of axis members 530 rotate in the first rotation direction R1, the first inclined surfaces 535 may press the second inclined surfaces 565 in the first direction D1 (e.g., the first direction D1 of FIG. 6B). When the second inclined surfaces 565 are pressed by the first inclined surfaces 535, the plurality of locking members 560 may move in the first direction D1.

In an embodiment, when the plurality of locking members 560 move in the first direction D1, each pin region 561 of the locking members 560 may also move in the first direction D1 and move into the housing 510. In addition, when the locking members 560 move in the first direction D1, the elastic member 570 may be pressed and compressed. As the pin regions 561 of the locking members 560 move into the housing 510, they may be released from pin grooves (not shown) of the electronic device, thereby releasing the fixation between the accessory device 500 and the electronic device.

In an embodiment, the lever 550 may rotate in a direction toward the strap 525 to release the fixation of the accessory device 500. Since the user operates the lever 550 by pulling the strap 525, the user may intuitively operate the lever 550 and easily release the fixation of the accessory device 500.

In an embodiment, when the lever 550 rotates from the state shown in FIG. 7B to the state shown in FIG. 7A, each pin region 561 of the locking members 560 may move to the outside of the housing 510. For example, when the external force applied to the lever 550 decreases or is removed, the elastic restoring force of the elastic member 570 may move the locking members 560 in the second direction D2 (e.g., the second direction D2 of FIG. 6B).

In an embodiment, when the locking members 560 move in the second direction D2, the pin regions 561 of the locking members 560 may also move in the second direction D2 and to the outside of the housing 510. As the pin regions 561 move to the outside of the housing 510, they may be inserted into pin grooves (not shown) of the electronic device, thereby fixing the accessory device 500 to the electronic device.

In an embodiment, when the locking members 560 move in the second direction D2, the second inclined surfaces 565 may press the first inclined surfaces 535 in the second direction D2. When the first inclined surfaces 535 are pressed in the second direction D2, the axis members 530 may rotate in a second rotation direction (e.g., the second rotation direction R2 of FIG. 4A). The lever 550, interlocking with the axis members 530, may also rotate in the second rotation direction R2 and move farther from the strap 525.

In an embodiment, the user may hold the strap 525 and press the lever 550 to a position adjacent to the strap 525 to connect or disconnect the accessory device 500 to or from the electronic device. Since the user may press the lever 550 in the direction in which the strap 525 is held, the user may, for example, hold both the strap 525 and the lever 550 with one hand, thereby easily securing the accessory device 500 to the electronic device.

In an embodiment, through the structure and arrangement of the components described above, the accessory device 500 may improve spatial efficiency of its internal components and reduce overall volume and weight. Accordingly, the accessory device 500 may provide improved wearability, simplify manufacturing, and enhance manufacturing economy and efficiency. In addition, by improving spatial efficiency, sufficient space may be ensured for the pressing region 555 of the lever 550, which may have a shape extending along the rotation axis Rx.

In an embodiment, by including a lever 550 having a shape that is easy to operate, the accessory device 500 may be fixed to or released from the electronic device easily and conveniently without the need for additional tools or assistance from an expert, thereby improving user convenience.

In an embodiment, the plurality of axis members 530 may move in response to the movement of the single lever 550. Therefore, the two pin regions 561 of the locking members 560 provided on both sides of the accessory device 500 may simultaneously move into or out of the housing 510. As the two pin regions 561 move together by the operation of a single lever 550, the user may more easily fix or release the fixation of the accessory device 500 to or from the electronic device, thereby enhancing user convenience.

FIG. 8A is a perspective view of an accessory device 600 according to an embodiment of the disclosure.

FIG. 8B is an exploded perspective view of a portion of components of the accessory device 600 according to an embodiment of the disclosure. Specifically, FIG. 8B is an exploded perspective view illustrating an axis member 630, a locking member 660, and an elastic member 670 disposed inside a housing 610.

Referring to FIGS. 8A and 8B, the accessory device 600 according to various embodiments of the disclosure may include at least some of a housing 610, an axis member 630, a locking member 660, and an elastic member 670.

Hereinafter, descriptions that are repeated with the foregoing will be omitted for brevity. It should be understood that certain components and structures of the accessory device 600 may be substituted, added, or omitted within a scope easily understood by those skilled in the art with reference to the following drawings and descriptions. In addition, the accessory device 600 may include at least one component or feature of the embodiments described above, unless such combination is technically impossible.

In an embodiment, the accessory device 600 (e.g., the coupling members 250 and 260 of FIGS. 2A and 2B, the coupling members 381 and 382 of FIGS. 3A and 3B, the accessory device 400 of FIGS. 4A, 4B, 5A, and 5B, or the accessory device 500 of FIGS. 6A, 6B, 7A, and 7B) may be detachably connected to at least a portion of an electronic device (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). Alternatively, the accessory device 600 may be a part of the electronic device or be physically and/or electrically connectable to the electronic device or to another connection device.

For example, the accessory device 600 may assist a user in wearing the electronic device. Alternatively, the accessory device 600 may complement the function of the electronic device or enhance its usability. Alternatively, the accessory device 600 may be a fashion accessory.

The accessory device 600 illustrated in the drawings shows an example in which the electronic device is the main body of a smartwatch, and the accessory device 600 is coupled to the main body. However, the structure and function of the accessory device 600 according to various embodiments of the disclosure are not limited thereto.

In an embodiment, the housing 610 may be the body of the accessory device 600 that is connected to the electronic device. The housing 610 may accommodate at least some components of the accessory device 600. One end of the housing 610 may be connected to a strap 625.

In an embodiment, the strap 625 may be worn on a user’s body to support the electronic device. For example, when the electronic device is the main body of a smartwatch, the strap 625 may be worn on a user's wrist. However, the strap 625 is not limited thereto and may be implemented in various forms. For example, the strap 625 may be replaced with a cable, a plate-shaped member, a three-dimensional structure, or an external electronic or communication device. Alternatively, the strap 625 may be replaced with an auxiliary device that accommodates electronic components (e.g., a battery, a communication module, or an input/output module) and is functionally linked to the main body of the electronic device.

In an embodiment, the accessory device 600 may include an outer cover 627 that surrounds at least a portion of an outer circumferential surface of the housing 610. The outer cover 627 may connect the housing 610 and the strap 625. The outer cover 627 may be integrally formed with the strap 625 or may be separately formed and fixed to the strap 625.

In an embodiment, the outer cover 627 may be formed of leather, synthetic leather, fabric, TPU, or a rubber mold. The outer cover 627 may cover not only the housing 610 but also the entire or most of an outer circumferential surface of the strap 625.

In an embodiment, the housing 610 may include a first housing region 611 and a second housing region 612. The first housing region 611 and the second housing region 612 may be implemented as an integral body or may be separately formed and joined together.

For example, the first housing region 611 may be an upper housing region facing upward (e.g., in a +Z direction) or an inner housing region facing inward with respect to a user's body when the electronic device is worn. The second housing region 612 may be a lower housing region facing downward or an outer housing region facing outward with respect to the user's body.

In an embodiment, the housing 610 may include a receiving groove 615 and a pin hole 617. For example, the receiving groove 615 and the pin hole 617 may be provided between the first housing region 611 and the second housing region 612. The receiving groove 615 and the pin hole 617 may be arranged adjacent to each other along a rotation axis Rx. The pin hole 617 may be formed to penetrate from the receiving groove 615 through to the outside of the housing 610.

In an embodiment, the housing 610 may further include a wing region 620. The wing region 620 may be provided at a position above the center C of the inner side of the housing 610 (e.g., in the -Z direction). The wing region 620 may be formed of a material different from that of the housing 610 and may be coupled to the housing 610.

For example, the housing 610 may be formed of a material, such as polycarbonate (PC), having relatively high rigidity. The wing region 620 may be formed of a material, such as rubber or silicone, having a relatively high coefficient of friction.

For example, the wing region 620 may be formed in the first housing region 611 and, compared to other portions of the first housing region 611, may have a shape that extends further upward (e.g., in the -Z direction) and protrudes.

In an embodiment, the wing region 620 may limit the movement range of the electronic device and the accessory device 600 while the accessory device 600 is worn by the user and prevent the electronic device and the accessory device 600 from freely rotating or moving on the user's body.

For example, the wing region 620 may protrude toward the user and contact the user's body. The wing region 620 may limit movement of the electronic device and the accessory device 600 by a frictional force acting on a contact portion with the user.

In various embodiments of the disclosure, the wing region 620 may improve the stability of wearing the accessory device 600. In addition, the wing region 620 may limit the position at which the electronic device is worn and the range of free movement of the electronic device and assist the electronic device in implementing its functions (e.g., a display function, a surrounding environment sensing function, or a user state sensing function). Furthermore, in various embodiments of the disclosure, the wing region 620 may be formed of a material different from that of the housing 610 such that the accessory device 600 may further enhance a frictional force of the wing region 620, and the wing region 620 may provide an enhanced effect.

In an embodiment, the axis member 630 may be rotatably disposed in the receiving groove 615 in the first rotation direction R1 or the second rotation direction R2 opposite to the first rotation direction R1 about the rotation axis Rx. The axis member 630 may be a pillar-shaped or cylinder-shaped structure extending along the rotation axis Rx.

In an embodiment, the axis member 630 may be connected to a lever 650 extending outside the housing 610 and may rotate about the rotation axis Rx to move the locking member 660. The axis member 630 may include a through hole 631 and a first inclined surface 635.

In an embodiment, the through hole 631 may be open along the rotation axis Rx. The through hole 631 may be an opening through which a pin region 661 of the locking member 660 is disposed. The through hole 631 may be arranged coaxially with the pin region 661 of the locking member 660 along the rotation axis Rx.

In an embodiment, the first inclined surface 635 may be a surface of the axis member 630 that faces the inner center C of the housing 610. Alternatively, the first inclined surface 635 may be a surface of the axis member 630 that faces the locking member 660.

In an embodiment, the first inclined surface 635 may be a surface inclined at a predetermined angle with respect to the rotation axis Rx. For example, the first inclined surface 635 may be inclined at a predetermined angle in a direction horizontal to the rotation axis Rx, based on a plane perpendicular to the rotation axis Rx. For example, the predetermined angle may be any angle within a range of 20 degrees to 70 degrees, 30 degrees to 60 degrees, or 40 degrees to 50 degrees.

In an embodiment, the lever 650 may be connected to the axis member 630 and may protrude outward from the housing 610. The lever 650 may be integrally formed with the axis member 630 or may be separately formed and coupled to the axis member 630. When an external force is applied (e.g., by a user) to the lever 650, the lever 650 may rotate about the rotation axis Rx. The lever 650 may rotate to cause the locking member 660 to rotate. The rotation axis Rx of the lever 650 may be aligned with the rotation axis Rx of the axis member 630.

In an embodiment, the locking member 660 may be movably disposed in the receiving groove 615 along the rotation axis Rx in the first direction D1 (e.g., the +Y direction) toward the inner center C of the housing 610 or in the second direction D2 (e.g., the -Y direction) opposite to the first direction D1. The locking member 660 may include a pin region 661 and a second inclined surface 665.

In an embodiment, the locking member 660 may move in response to the rotation of the axis member 630. As the locking member 660 moves, the pin region 661 may move from inside to outside the housing 610 or from outside to inside the housing 610.

In an embodiment, the pin region 661 may be disposed to penetrate the through hole 631 and the pin hole 617. The pin region 661 may selectively fix the accessory device 600 to an electronic device or to an external connection device.

For example, the pin region 661 disposed outside the housing 610 may be inserted into a pin groove (not shown) of the electronic device, thereby fixing the accessory device 600 to the electronic device. In addition, the pin region 661 may move into the housing 610 and be separated from the pin groove (not shown) of the electronic device, thereby releasing the accessory device 600 from the electronic device.

In an embodiment, the second inclined surface 665 may be a surface of the locking member 660 that faces the first inclined surface 635. Alternatively, the second inclined surface 665 may be a surface of the locking member 660 that faces the outside of the housing 610.

In an embodiment, the second inclined surface 665 may be inclined at a predetermined angle with respect to the rotation axis Rx. For example, the second inclined surface 665 may be inclined at the same or a similar predetermined angle as the first inclined surface 635. Alternatively, the second inclined surface 665 may be a curved surface having a predetermined curvature in at least a partial region.

In an embodiment, the second inclined surface 665 may be pressed by the first inclined surface 635. The second inclined surface 665 may engage with the first inclined surface 635 and may be pressed in response to the rotation of the first inclined surface 635. As the second inclined surface 665 is pressed, the locking member 660 may move.

In an embodiment, the elastic member 670 may be disposed between the locking member 660 and the receiving groove 615. One end of the elastic member 670 may contact the locking member 660, and the other end of the elastic member 670 may be disposed to contact the receiving groove 615. For example, one end of the elastic member 670 may contact a surface of the locking member 660 opposite to the second inclined surface 665.

In an embodiment, the elastic member 670 may be compressed when the locking member 660 moves in the first direction D1. In addition, the elastic member 670 may be tensioned when the locking member 660 moves in the second direction D2. After being compressed, the elastic member 670 may press the locking member 660 in the second direction D2. When the force pressing the locking member 660 in the first direction D1 is removed, the elastic restoring force of the elastic member 670 may move the locking member 660 in the second direction D2. The interlocking structure of the axis member 630 and the locking member 660, according to an embodiment of the disclosure, will be described with reference to FIGS. 9A and 9B.

In an embodiment, the housing 610 may further include an auxiliary accommodation groove 616 and an auxiliary pin hole 618. The auxiliary accommodation groove 616 may be disposed adjacent to the accommodation groove 615 along the rotation axis RX, and, for example, in a direction opposite to the pin hole 617 from the accommodation groove 615. The auxiliary pin hole 618 may be disposed adjacent to the auxiliary accommodation groove 616 along the rotation axis RX, and, for example, in a direction opposite to the accommodation groove 615 from the auxiliary accommodation groove 616.

In an embodiment, the auxiliary pin hole 618 may be formed to penetrate from the auxiliary accommodation groove 616 to the outside of the housing 610. For example, the pin hole 617 may be formed on one side (e.g., a surface in the -Y direction) of the housing 610, and the auxiliary pin hole 618 may be formed on the other side (e.g., a surface in the +Y direction) of the housing 610.

In an embodiment, the accessory device 600 may further include an auxiliary axis member 680 and an auxiliary elastic member 675. The auxiliary axis member 680 may include an auxiliary pin region 687. The auxiliary pin region 687 may extend along the rotation axis Rx and may be disposed to penetrate the auxiliary pin hole 618. The auxiliary elastic member 675 may be disposed such that one end contacts the auxiliary axis member 680 and the other end contacts the auxiliary accommodation groove 616.

In an embodiment, the auxiliary elastic member 675 and the auxiliary axis member 680 may operate the locking of the accessory device 600 and the electronic device independently of the movement of the axis member 630 caused by the lever 650.

For example, the user may press the auxiliary axis member 680 to compress the auxiliary elastic member 675, move the accessory device 600 in that state, and thereby insert the auxiliary pin region 687 of the auxiliary axis member 680 into a pin groove (not shown) of the electronic device. Even when the movement of at least some of the lever 650, the axis member 630, and the elastic member 670 is restricted, the accessory device 600 may fix to or be released from the electronic device.

In an embodiment, the lever 650 may be connected to the axis member 630. The lever 650 may include a connection region and a pressing region 655. The connection region may be connected to the axis member 630, and the pressing region 655 may be disposed outside the housing 610 to be pressed by an external force. The connection region may be a connecting pillar that connects the axis member 630 and the pressing region 655.

In an embodiment, when the pressing region 655 is pressed, the lever 650 may rotate about the rotation axis Rx. The pressing region 655 may have a shape extending along the rotation axis Rx, allowing the user to easily operate the lever 650 without the need for additional tools or expert assistance.

In an embodiment of the disclosure, the lever 650 may be spaced apart at a predetermined distance from the wing region 620. With the lever 650 spaced apart from the wing region 620, the exposed area of the wing region 620 may be increased, and the effect of the wing region 620 may be enhanced. In addition, by miniaturizing the lever 650, the space efficiency of the accessory device 600 may be improved, and the structure may be simplified.

FIG. 9A is an internal perspective view of the accessory device 600 according to an embodiment of the disclosure.

FIG. 9B is an internal perspective view of the accessory device 600 according to an embodiment of the disclosure. Specifically, FIGS. 9A and 9B are internal perspective views illustrating a state in which a portion of the outer cover 627 and the first housing region 611 of the housing 610 are omitted.

Referring to FIGS. 9A and 9B, the accessory device 600 according to various embodiments of the disclosure may cause the pin region 661 of the locking member 660 to move in response to the movement of the lever 650.

Hereinafter, descriptions overlapping with the foregoing will be omitted for brevity. It should be understood that, in the accessory device 600, some components and structures may be substituted, added, or omitted within a scope easily understood by those skilled in the art with reference to the following drawings and descriptions. In addition, at least one component or feature of the above-described embodiments may be combined in the accessory device 600, unless technically impossible.

In an embodiment, when the lever 650 rotates from the state of FIG. 9A to the state of FIG. 9B, the pin region 661 of the locking member 660 may move into the housing 610. For example, a first rotation direction (e.g., the first rotation direction R1 of FIG. 8A) may be a direction in which the lever 650 moves closer to the strap 625. A second rotation direction (e.g., the second rotation direction R2 of FIG. 8A) may be a direction in which the lever 650 moves away from the strap 625.

In an embodiment, when the lever 650 is pressed and rotated in the first rotation direction R1, the axis member 630, interlocking with the lever 650, may rotate in the first rotation direction R1. When the axis member 630 rotates in the first rotation direction R1, the first inclined surface 635 may press the second inclined surface 665 in a first direction (e.g., the first direction D1 of FIG. 8B). When the second inclined surface 665 is pressed by the first inclined surface 635, the locking member 660 may move in the first direction D1.

In an embodiment, when the locking member 660 moves in the first direction D1, the pin region 661 may also move in the first direction D1 and move into the housing 610. In addition, when the locking member 660 moves in the first direction D1, the elastic member 670 may be pressed and compressed. Once moving into the housing 610, the pin region 661 may be detached from a pin groove (not shown) of an electronic device, thereby releasing the fixation between the accessory device 600 and the electronic device.

In an embodiment of the disclosure, by rotating the lever 650 in a direction toward the strap 625, the fixation of the accessory device 600 may be released. Since the user operates the lever 650 in the same direction as pulling the strap 625, the operation may be performed intuitively, allowing the user to easily and conveniently release the fixation of the accessory device 600.

In an embodiment, when the lever 650 rotates from the state of FIG. 9B to the state of FIG. 9A, the pin region 661 of the locking member 660 may move to the outside of the housing 610. For example, when the external force pressing the lever 650 is reduced or removed, the elastic restoring force of the elastic member 670 may move the locking member 660 in a second direction (e.g., the second direction D2 of FIG. 8B).

In an embodiment, when the locking member 660 moves in the second direction D2, the pin region 661 may move to the outside of the housing 610 in the second direction D2. Upon moving to the outside of the housing 610, the pin region 661 may be inserted into the pin groove (not shown) of the electronic device, thereby fixing the accessory device 600 to the electronic device.

In an embodiment, when the locking member 660 moves in the second direction D2, the second inclined surface 665 may press the first inclined surface 635 in the second direction D2. When the first inclined surface 635 is pressed in the second direction D2, the axis member 630 may rotate in the second rotation direction R2. The lever 650, interlocking with the axis member 630, may rotate in the second rotation direction R2 and move to a position away from the strap 625.

In an embodiment of the disclosure, while holding the strap 625, the user may press the lever 650 at a position adjacent to the strap 625, thereby connecting or disconnecting the accessory device 600 to or from the electronic device. Since the user may press the lever 650 in the direction in which the strap 625 is held, the user may, for example, hold both the strap 625 and the lever 650 with one hand, thereby easily securing the accessory device 600 to the electronic device.

In an embodiment of the disclosure, the accessory device 600 may secure spatial efficiency of its components through the structure and arrangement of the elements and may reduce the overall volume and weight of the accessory device 600. Through this, the accessory device 600 may provide improved wearability, simplify the manufacturing process, and enhance manufacturing economy and efficiency.

In addition, in an embodiment of the disclosure, the accessory device 600 may include the lever 650 shaped for easy user operation, allowing the user to fix or release the accessory device 600 easily and conveniently without the need for additional tools or expert assistance, thereby providing user convenience.

FIG. 10A is an internal perspective view of an accessory device 700 according to an embodiment of the disclosure.

FIG. 10B is an internal perspective view of the accessory device 700 according to an embodiment of the disclosure.

Referring to FIGS. 10A and 10B, the first rotation direction R1 and the second rotation direction R2 may be variously configured in the accessory device 700.

Hereinafter, descriptions overlapping with the foregoing will be omitted for brevity. It should be understood that some components and structures of the accessory device 700 may be substituted, added, or omitted within a scope easily understood by those skilled in the art with reference to the following drawings and descriptions. In addition, at least one component or feature of the above-described embodiments may be incorporated into the accessory device 700, unless technically impossible.

In an embodiment, the accessory device 700 (e.g., the engagement members 250 and 260 of FIGS. 2A and 2B, the engagement members 381 and 382 of FIGS. 3A and 3B, the accessory device 400 of FIGS. 4A, 4B, 5A, and 5B, the accessory device 500 of FIGS. 6A, 6B, 7A, and 7B, or the accessory device 600 of FIGS. 8A, 8B, 9A, and 9B) may be detachably connected to at least a portion of a component of an electronic device (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).

In an embodiment, the accessory device 700 may include at least some of a housing 710, an axis member 730, a lever 750, a locking member 760, and an elastic member 770. Descriptions for components having the same or similar terms as those described above may be identically or similarly applied to these components, unless explicitly stated otherwise or excluded.

In an embodiment, when the lever 750 rotates from the state of FIG. 10A to the state of FIG. 10B, a pin region 761 of the locking member 760 may move into the housing 710. For example, the first rotation direction R1 may be a direction in which the lever 750 moves to a position farther away from the strap 725, and the second rotation direction R2 may be a direction in which the lever 750 moves closer to the strap 725.

In an embodiment, when the lever 750 is pressed and rotated in the first rotation direction R1, the axis member 730, interlocking with the lever 750, may rotate in the first rotation direction R1. When the axis member 730 rotates in the first rotation direction R1, a first inclined surface 735 may press a second inclined surface 765 in the first direction D1. When the second inclined surface 765 is pressed by the first inclined surface 735, the locking member 760 may move in the first direction D1.

In an embodiment, when the locking member 760 moves in the first direction D1, the pin region 761 may move in the first direction D1 and may move into the housing 710. In addition, when the locking member 760 moves in the first direction D1, the elastic member 770 may be pressed and compressed. By moving into the housing 710, the pin region 761 may be separated from a pin groove (not shown) of the electronic device and may release the fixation between the accessory device 700 and the electronic device.

In an embodiment, when the lever 750 rotates from the state of FIG. 10B to the state of FIG. 10A, the pin region 761 of the locking member 760 may move to the outside of the housing 710. For example, when the external force pressing the lever 750 is reduced or removed, the elastic restoring force of the elastic member 770 may move the locking member 760 in the second direction D2.

In an embodiment, when the locking member 760 moves in the second direction D2, the pin region 761 may also move in the second direction D2 and may move to the outside of the housing 710. By moving to the outside of the housing 710, the pin region 761 may be inserted into the pin groove (not shown) of the electronic device, thereby fixing the accessory device 700 to the electronic device.

In an embodiment, when the locking member 760 moves in the second direction D2, the second inclined surface 765 may press the first inclined surface 735 in the second direction D2. When the first inclined surface 735 is pressed in the second direction D2, the axis member 730 may rotate in the second rotation direction R2. The lever 750, interlocking with the axis member 730, may rotate in the second rotation direction R2, and move to a position adjacent to the strap 725.

In an embodiment of the disclosure, the fixation of the accessory device 700 may be released by rotating the lever 750 in a direction away from the strap 725. When not pulled by the user, the lever 750 may be disposed relatively close to, or in contact with, the strap 725, thereby reducing or preventing the risk that the lever 750 is unintentionally moved by external force or pulled without the user's intention to release the fixation of the accessory device 700.

FIG. 11A is a perspective view of an accessory device 800 according to an embodiment of the disclosure.

FIG. 11B is an exploded perspective view of some components of the accessory device 800 according to an embodiment of the disclosure.

Referring to FIGS. 11A and 11B, in an embodiment, a strap 825 and a housing 810 of the accessory device 800 may be formed as an integral structure at least in a partial region (e.g., a second housing region 812).

Hereinafter, descriptions repeated with the foregoing will be omitted for brevity. It should be understood that some components and structures of the accessory device 800 may be substituted, added, or omitted within a scope easily understood by those skilled in the art with reference to the following drawings and descriptions. In addition, the accessory device 800 may include at least one component or feature of the above-described embodiments, unless technically impossible.

In an embodiment, the accessory device 800 (e.g., the engagement members 250 and 260 in FIGS. 2A and 2B, the engagement members 381 and 382 in FIGS. 3A and 3B, the accessory device 400 in FIGS. 4A, 4B, 5A, and 5B, the accessory device 500 in FIGS. 6A, 6B, 7A, and 7B, the accessory device 600 in FIGS. 8A, 8B, 9A, and 9B, or the accessory device 700 in FIGS. 10A and 10B) may be detachably connected to at least one component of an electronic device (e.g., the electronic device 101 in FIG. 1 or the electronic device 200 in FIGS. 2A and 2B or the electronic device 300 in FIGS. 3A and 3B).

In an embodiment, the accessory device 800 may include at least some of a housing 810, a wing region 820, an axis member 830, a lever 850, a locking member 860, a pin region 861, and an elastic member 870. Unless otherwise stated to be excluded or contradictory, these components may be the same as or similar to the components having the same terms described above with different drawing numbers.

In an embodiment, the housing 810 may serve as the body of the accessory device 800 that is connected to an electronic device. The housing 810 may accommodate some of the components of the accessory device 800 therein. The housing 810 may be connected to the strap 825 at least in a partial region. For example, a portion of the housing 810 and the strap 825 may be formed as a single body.

In an embodiment, the housing 810 may include a first housing region 811 and a second housing region 812. For example, the first housing region 811 may be an upper housing region facing upward (e.g., in the +Z direction) or an inner housing region facing the body of the user of the electronic device, and the second housing region 812 may be a lower housing region facing downward or an outer housing region facing away from the user's body.

In an embodiment, the second housing region 812 may be formed integrally with the strap 825. The first housing region 811 may be formed as a separate component detachable from the second housing region 812 and may be fastened thereto. For example, the strap 825 may form the structure of the second housing region 812 by mold forming.

In an embodiment, a receiving groove 815 may be disposed between the first housing region 811 and the second housing region 812, and a first pin hole 817a and a second pin hole 817b may be disposed in the second housing region 812. The receiving groove 815, the first pin hole 817a, and the second pin hole 817b may be arranged adjacent to each other along the rotation axis Rx. The first pin hole 817a and the second pin hole 817b may be formed to penetrate from the receiving groove 815 to the outside of the housing 810.

In various embodiments of the disclosure, since the second housing region 812 is formed on the strap 825, the accessory device 800 may omit a structure for connecting the housing 810 and the strap 825 and may improve the fastening reliability between the housing 810 and the strap 825. In addition, the accessory device 800 may secure spatial efficiency of its components and reduce the volume and weight of the accessory device 800.

In an embodiment, an accessory device 400, 500, 600, 700, or 800 may include a housing 410, 510, 610, 710, or 810 including a receiving groove 415, 515, 615, 715, or 815 and a pin hole 417, 517, 617, 717, or 817 that penetrates from the receiving groove to an outside; an axis member 430, 530, 630, 730, or 830 that is rotatably disposed in the receiving groove 415, 515, 615, 715, or 815 in a first rotation direction R1 or a second rotation direction R2 opposite to the first rotation direction R1 about a rotation axis Rx, the axis member including a through hole 431, 531, 631, 731, or 831 that opens along the rotation axis Rx and a first inclined surface 435, 535, 635, 735, or 835 facing an inner center C of the housing; a lever 450 that is connected to the axis member and rotates about the rotation axis Rx to cause the axis member to rotate; a locking member 460, 560, 660, 760, or 860 that is movably disposed in the receiving groove along the rotation axis Rx in a first direction D1 toward the inner center C of the housing or in a second direction D2 opposite to the first direction D1, the locking member including a pin region 461 that penetrates the through hole and the pin hole and a second inclined surface 465, 565, 665, 765, or 865 facing the first inclined surface; and an elastic member 470, 570, 670, 770, or 870 that is compressed when the locking member moves in the first direction D1. In an embodiment, when the axis member rotates in the first rotation direction R1, the first inclined surface may press the second inclined surface, causing the locking member to move in the first direction D1.

In an embodiment, the housing 410, 510, 610, 710, or 810 may further include a wing region 420 that is provided above the inner center C and protrudes to the outside of the housing.

In an embodiment, the housing 410, 610, or 710 may further include an auxiliary receiving groove 416, 615, or 715 disposed in a direction opposite to the pin hole from the receiving groove. The accessory device 400, 600, or 700 may further include an auxiliary axis member 480, 680, or 780 that is rotatably disposed in the auxiliary receiving groove in the first rotation direction R1 or the second rotation direction R2 about the rotation axis Rx.

In an embodiment, the housing 410, 610, or 710 may further include an auxiliary pin hole 418, 618, or 718 that penetrates from the receiving groove to the outside.

In an embodiment, the auxiliary axis member 480, 680, or 780 may include an auxiliary pin region 487, 687, or 787 that penetrates the auxiliary pin hole.

In an embodiment, the lever 450 or 750 may include a first connection region 451 or 751 that faces one side surface of the wing region 420 or 720 and is connected to the axis member 430 or 730, a second connection region 452 or 752 that faces another side surface opposite to the side surface of the wing region and is connected to the auxiliary axis member 480 or 780, and a pressing region 455 or 755 that extends across the wing region from the first connection region to the second connection region.

In an embodiment, the accessory device 500 may include a plurality of axis members 530 and a plurality of locking members 560. The plurality of axis members may include a first axis member 530a and a second axis member 530b spaced apart from each other at both sides of the inner center C of the housing 510. The plurality of locking members may include a first locking member 560a that faces the first axis member and a second locking member 560b that faces the second axis member.

In an embodiment, the elastic member 570 may be disposed such that one end contacts the first locking member 560a and the other end contacts the second locking member 560b.

In an embodiment, the lever 550 may include a first connection region 551 that faces one side surface of the wing region 520 and is connected to the first axis member 530a, a second connection region 552 that faces another side surface opposite to the side surface of the wing region and is connected to the second axis member 530b, and a pressing region 555 that extends across the wing region from the first connection region to the second connection region.

In an embodiment, the lever 650 may be spaced apart from the wing region 620 by a predetermined distance and may extend from the axis member 630 to the outside of the housing 610.

In an embodiment, the wing region 420, 520, 720, or 820 may be integrally formed with the housing 410, 510, 710, or 810.

In an embodiment, the wing region 620 may be formed of a material different from that of the housing 610 and may be coupled to the housing.
