ELECTRONIC DEVICE USING STRAP, AND FASTENING DEVICE OF STRAP

BACKGROUND

Various embodiments of the disclosure relate to a fastening structure capable of attaching/detaching a strap in an electronic device using the strap.

In general, an electronic device may refer to a device that performs a specific function according to a program. The electronic device may include electronic schedulers, portable multimedia players, mobile communication terminals, tablet PCs, audio/video devices, desktop/laptop computers, or vehicle navigation systems. In recent years, as the integration of electronic devices increases and wireless communication is commonplace, various functions may be equipped in mobile communication terminals, such as smartphones. For example, a mobile communication terminal packs various features for entertainment, e.g., playing video games, multimedia, e.g., playing music/video, security for mobile banking, or as a scheduler or e-wallet, as well as communication capabilities.

As electronic and communication technology advances, electronic devices are becoming smaller to be conveniently carried and worn by users. Electronic devices have become so small or lightweight that users may use them without any discomfort, even when worn on the body. For example, in addition to mobile communication devices, such as smartphones, users are increasingly using wearable devices, such as wireless earphones or smartwatches that may be connected to smartphones.

Wearable devices are being developed with the goal of increasing portability and diversifying functions. For convenience of portability, there may be assistant devices that assist in carrying or wearing the wearable device. For example, in relation to a watch-type wearable device, there may be a strap to assist wearing.

The strap that assists in wearing the wearable device may be replaced by the user as needed. For this purpose, the strap needs to have a fastening structure to be mounted on the main body of the wearable device or easy to attach and detach.

As an embodiment, a mounting recess (not shown) may be formed in one surface (e.g., in the z direction) of the support member 272. The battery 271 may be mounted in the mounting recess formed in one surface of the support member 272.

According to an embodiment, components for operating the electronic device 200 may be disposed on the printed circuit board 280. For example, at least one of a processor (e.g., the processor 120 of FIG. 1), a memory (e.g., the memory 130 of FIG. 1), and an interface (e.g., the interface 177 of FIG. 1) may be disposed on the printed circuit board 280.

FIG. 3 is a perspective view illustrating a portion of a strap (e.g., the first strap 250 of FIG. 2A) in an electronic device (e.g., the electronic device 200 of FIG. 2A) according to an embodiment.

FIG. 4A is a perspective view illustrating one of the fastening pins (e.g., the fastening pin 290a and 290b of FIG. 2B) illustrated in FIG. 3.

FIG. 4B is a disassembled perspective view illustrating the fastening pin (e.g., the fastening pin 290a and 290b of FIG. 2B) illustrated in FIG. 4A.

Although only one strap (e.g., the first strap 250 of FIG. 2A) is illustrated in FIG. 3, at least one configuration of the second strap (e.g., the second strap 260 of FIG. 2A) may correspond to the first strap 250 in terms of operation, structure, or shape. For example, the second strap 260 may include a second pressing portion (not shown) and a second fastening pin (e.g., the second fastening pin 290b of FIG. 2B). Each of the second pressing portion of the second strap 260 and the second fastening pin 290b may have a structure corresponding to the first pressing portion 256 of the first strap 250 or the first fastening pin (e.g., the first fastening pin 290a of FIG. 2B). In this case, the description of the first pressing portion 256 or the first fastening pin 290a may be equally applied to the second pressing portion or the second fastening pin 290b.

Referring to FIGS. 3 to 4B, in an embodiment, the first strap 250 may include a first pressing portion 256 or a first fastening pin 290a.

According to an embodiment, the first pressing portion 256 may be disposed at one end 250a of the first strap 250. In an embodiment, the first pressing portion 256 may be formed to be open toward the housing (e.g., the housing 210 of FIG. 2A). In an embodiment, the first pressing portion 256 may be formed by being recessed from one end 250a of the first strap 250. In an embodiment, the first pressing portion 256 may correspond to at least a portion of the first strap 250 to which the user applies pressure. For example, when the user presses the upper portion of the first strap 250, at least a portion of the first strap 250 (e.g., the upper portion of the first strap 250) may be deformed (or bent) toward the first pressing portion 256 by the pressing.

According to an embodiment, the first fastening pin 290a may be coupled to one end 250a of the first strap 250. In an embodiment, the first fastening pin 290a may be configured to pass through one end 250a of the first strap 250. In an embodiment, the first fastening pin 290a may be inserted into first fastening grooves (e.g., the first fastening grooves 241 of FIG. 2C) provided in a pair of first lugs (e.g., the pair of first lugs 240a of FIG. 2C). In an embodiment, when an external force (e.g., an operation of the user) is applied to the first strap 250, the first fastening pin 290a may move along a path provided by the first fastening groove 241. For example, corresponding to the direction of the external force applied to the first strap 250, the first fastening pin 290a may be seated on the end of the first fastening groove 241 so that the first strap 250 is coupled (or mounted) to the pair of first lugs 240a, or may be separated from the start end of the first fastening groove 241 of the first fastening pin 290a so that the first strap 250 is removed (or detached) from the pair of first lugs 240a.

According to an embodiment, the first fastening pin 290a may include a pin body 291, a first pin 292, a second pin 293, a pin handle 294, or a pin spring 295.

According to an embodiment, the pin body 291 may form the appearance of the first fastening pin 290a. In an embodiment, the fin body 291 may be configured to have a substantially cylindrical shape.

According to an embodiment, a fastening hole 291h may be disposed in the outer circumferential surface of the fin body 291. In an embodiment, the fastening hole 291h may be formed to be open along the length direction (e.g., the first direction DR1 or the second direction DR2) of the pin body 291.

According to an embodiment, at least a portion of the first pin 292 may be accommodated in the pin body 291. In an embodiment, at least a portion of the first pin 292 may be inserted into the pin body 291 from one side. In an embodiment, a fitting hole 292h may be disposed in the outer circumferential surface of the first pin 292. In an embodiment, the fitting hole 292h may be formed as an opening in the outer circumferential surface of the first pin 292 to have a shape corresponding to the pin handle 294.

According to an embodiment, at least a portion of the second pin 293 may be accommodated in the pin body 291. In an embodiment, at least a portion of the second pin 293 may be inserted into the pin body 291 from the other side.

According to an embodiment, the pin handle 294 may be inserted into the fitting hole 292h to be coupled to the first pin 292. In an embodiment, the pin handle 294 may move the first pin 292 so that the area of the first pin 292 exposed to the outside from the pin body 291 increases or decreases. For example, when an external force (e.g., an operation of the user) is applied to the pin handle 294, the pin handle 294 may move in the first direction DR1 or the second direction DR2 along the fastening hole 291h corresponding to the direction in which the external force is applied. For example, the pin handle 294 may move the first pin 292 connected to the pin handle 294 in the first direction DR1 or the second direction DR2 within a limited range formed by the fastening hole 291h.

According to an embodiment, the pin spring 295 may be accommodated in the pin body 291. In an embodiment, the pin spring 295 may be disposed between the first pin 292 and the second pin 293. In an embodiment, one end of the pin spring 295 may contact the first pin 292 and the other end of the pin spring 295 may contact the second pin 293. For example, as the pin spring 295 is compressed/extended corresponding to the direction of the external force applied to the pin handle 294, the pin spring 295 may provide an elastic force (or restoring force) to the first pin 292 or the second pin 293.

FIG. 5 is a plan view illustrating a housing (e.g., the housing 210 of FIG. 2A) in an electronic device (e.g., the electronic device 200 of FIG. 2A) according to an embodiment.

FIG. 6 is a cross-sectional view taken along line A-A of FIG. 5.

FIG. 7 is a cross-sectional view taken along line B-B of FIG. 5.

FIG. 8 is a cross-sectional view taken along line C-C of FIG. 6.

FIG. 9 is a see-through view illustrating a strap (e.g., the straps 250 and 260 of FIG. 2A) is mounted to a lug (e.g., the lugs 240a and 240b of FIG. 2A) of a housing (e.g., the housing 510 of FIG. 2A) in an electronic device (e.g., the electronic device 200 of FIG. 2A) according to an embodiment.

Although FIGS. 6 to 9 illustrate only a pair of first lugs (e.g., the pair of first lugs 240a of FIG. 2A), the pair of second lugs (e.g., the pair of second lugs 240b of FIG. 2A) may be symmetrical to the pair of first lugs 240a in terms of operation, structure, or shape. For example, second fastening grooves (not shown) may be formed in the pair of second lugs 240b. The description of the first fastening groove 241 may be equally applied to the second fastening groove.

Referring to FIGS. 5 to 9, in an embodiment, a first fastening groove 241 may be disposed in one side surface of the pair of first lugs 240a. In an embodiment, the first fastening groove 241 may be formed by being recessed from one side surface of the pair of first lugs 240a. Here, the one side surface of the pair of first lugs 240a may refer to a surface facing the first strap 250 in a state in which the pair of first lugs 240a and the first strap (e.g., the first strap 250 of FIG. 2C) are coupled. In an embodiment, the first fastening groove 241 may provide a path through which a first fastening pin (e.g., the first fastening pin 290a of FIG. 2C) is inserted into the first fastening groove 241 to move when the first strap 250 is attached/detached.

According to an embodiment, the first fastening groove 241 may include a first guide groove 2411, a connecting groove 2412, or a second guide groove 2413.

According to an embodiment, the connecting groove 2412 may be formed to have at least one bend. For example, the connecting groove 2412 may include a bent portion connecting the first guide groove 2411 and the second guide groove 2413. In one embodiment, the angle of the bent portion (e.g., bend) of the connecting groove 2412 connecting the first guide groove 2411 and the second guide groove 2413 may be 60 degrees to 120 degrees.

According to an embodiment, the start end 241a (or an open end) of the first fastening groove 241 may form an opening in the rear side (e.g., in the −z direction) of the pair of first lugs 240a. In an embodiment, the first fastening pin 290a may be inserted into the start end 241a of the first fastening groove 241. The first fastening pin 290a may move along the first guide groove 2411, the connecting groove 2412, or the second guide groove 2413.

According to an embodiment, the first guide groove 2411 may be connected to the start end 241a of the first fastening groove 241. In an embodiment, the first guide groove 2411 may extend in a vertical direction (or a first direction) (e.g., a z direction) from the start end 241a of the first fastening groove 241. In an embodiment, the first guide groove 2411 may form a first straight section that is a path along which the first fastening pin 290a inserted into the first fastening groove 241 moves. In an embodiment, the first guide groove 2411 may be recessed from one side surface of the pair of first lugs 240a so that the depth of the groove gradually decreases toward the connecting groove 2412. For example, in order to insert the first fastening pin 290a into the first fastening groove 241, an external force required for the first fastening pin 290a increases, and the first fastening pin 290a is pressed.

According to an embodiment, one end of the connecting groove 2412 may be connected to the first guide groove 2411. The other end of the connecting groove 2412 may be connected to the second guide groove 2413. In an embodiment, the connecting groove 2412 may form a curved section that is a path along which the first fastening pin 290a inserted into the first fastening groove 241 moves.

According to an embodiment, the second guide groove 2413 may extend in a horizonal direction (or a second direction) (e.g., an x direction) from the connecting groove 2412. Here, the second direction may mean a direction perpendicular to, or crossing, the first direction. In an embodiment, the second guide groove 2413 may form a second straight section that is a path along which the first fastening pin 290a inserted into the first fastening groove 241 moves. In an embodiment, the second guide groove 2413 may be recessed from one side surface of the pair of first lugs 240a so that the depth of the groove gradually increases toward the second direction. In an embodiment, the second guide groove 2413 may be recessed from one side surface of the pair of first lugs 240a so that the recess surface is formed in parallel with the second direction (e.g., the x direction).

According to an embodiment, the end 241b (or a closed end) of the first fastening groove 241 may be closed by one side surface of the pair of first lugs 240a. For example, the end 241b of the first fastening groove 241 may mean the end point of the moving path of the first fastening pin 290a formed by the first fastening groove 241 (or the second guide groove 2413). The first fastening pin 290a inserted into the start end 241a of the first fastening groove 241 may reach the end 241b of the first fastening groove 241 through, e.g., the first guide groove 2411, the connecting groove 2412, or the second guide groove 2413. When the first fastening pin 290a reaches the end of the first fastening groove 241, coupling between the pair of first lugs 240a and the first strap 250 may be completed.

FIG. 10 is a plan view illustrating a housing (e.g., the housing 210 of FIG. 2A) in an electronic device (e.g., the electronic device 200 of FIG. 2A) according to an embodiment.

FIG. 11 is a cross-sectional view taken along line D-D of FIG. 10.

FIG. 12 is a view illustrating an operation of attaching/detaching a strap (e.g., the straps 250 and 260 of FIG. 2A) from a lug (e.g., the lugs 240a and 240b of FIG. 2A) of a housing (e.g., the housing 210 of FIG. 2A) in an electronic device (e.g., the electronic device 200 of FIG. 2A) according to an embodiment.

Although only the first strap 250 (e.g., the first strap 250 of FIG. 2A) is illustrated in FIGS. 11 and 12, the first strap 250 and the second strap 260 may have structures corresponding to each other in terms of operation, structure, and shape. In this case, the description of the first strap 250 may be equally applied to the second strap (e.g., the second strap 260 of FIG. 2A).

Referring to FIG. 10, in a state in which the straps 250 and 260 are coupled to the pair of lugs 240a and 240b, one end of the straps 250 and 260 may contact one side surface of the housing 210.

Referring to FIG. 11, in an embodiment, the first strap 250 may be divided into an upper portion 257 and a lower portion 258 with respect to a virtual center line CL passing through the center of the first strap 250. For example, the upper portion 257 may be positioned on one side (e.g., z direction) of the center line CL. The lower portion 258 may be positioned on the other side (e.g., in the −z direction) of the center line CL.

According to an embodiment, the first pressing portion 256 may be disposed on the upper portion 257 of the first strap 250, but is not limited thereto. According to an embodiment, the first pressing portion 256 may be disposed in the upper portion 257 or the lower portion 258 of the first strap 250. In an embodiment, the pressing portion 256 may be disposed closer to the upper portion 257 (or the upper surface of the first strap 250) than the lower portion 258 (or the rear surface of the first strap 250) with respect to the center line CL. In an embodiment, the thickness of the lower portion 258 of the first strap 250 may be set to be thicker than the thickness of the upper portion 257 of the first strap 250.

According to an embodiment, the first strap 250 may be formed of a rubber material, but is not limited thereto. In an embodiment, the first strap 250 may be configured so that materials of the upper portion 257 and the lower portion 258 are different from each other with respect to the first pressing portion 256. In an embodiment, the upper portion 257 and the lower portion 258 of the first strap 250 may be configured so that the hardness of the upper portion 257 of the first strap 250 positioned above the first pressing portion 256 (e.g., in the z direction) is different from the hardness of the lower portion 258 of the first strap 250 positioned below the first pressing portion 256 (e.g., in the −z direction). For example, the hardness of the upper portion 257 of the first strap 250 may be configured to be lower than that of the lower portion 258 of the first strap 250. For example, when an external force (e.g., the user's pressing operation) is applied to the upper portion 257 of the first strap 250 corresponding to the upper side of the pressing portion 256, deformation (or bending) of the upper portion 257 of the first strap 250 toward the first pressing portion 256 may be easy.

It may be identified that the upper portion 257 or the lower portion 258 of the first strap 250 is positioned outside the radius of the circle CC with respect to the virtual circle CC having the distance d from the first fastening pin 290a to one side surface of the housing 210 as a radius. For example, in a state in which the pair of first lugs 240a and the first strap 250 are coupled, at least a portion of the upper portion 257 or the lower portion 258 of the first strap 250 may contact the housing 210 and thus the movement (or rotation) of the first strap 250 is limited, thereby stably maintaining the coupling of the pair of first lugs 240a and the first strap 250.

Referring to FIG. 11, when an external force F (e.g., the user's pressing operation) is applied to the upper portion 257 (or the upper surface of the upper portion 257) of the first strap 250 positioned above the first pressing portion 256, at least a portion of the upper portion 257 of the first strap 250 adjacent to the housing 210 may be deformed (or bent) toward the first pressing portion 256. In this case, the opening formed by the first pressing portion 256 may also be deformed.

Although not specifically illustrated in the drawings, if the upper portion 257 of the first strap 250 is deformed (or bent) toward the first pressing portion 256 by the external force F, at least a portion of the upper portion of the first strap 250 may be positioned inside the radius of the virtual circle CC. For example, as illustrated in FIG. 12, if an external force (e.g., the user's pressing operation and the user's rotating operation) is applied to the first strap 250, the first strap 250 may be rotated so that the upper surface of the upper portion 257 of the first strap 250 faces one side surface of the housing 210. For example, if the user rotates the first strap 250 in the counterclockwise direction while pressing the upper portion 257 of the first strap 250, the upper surface of the upper portion 257 of the first strap 250 and one side surface of the housing 210 may face each other, forming a predetermined gap g between the first strap 250 and the housing 210. The gap g between the first strap 250 and the housing 210 may be set to be equal to or larger than, e.g., the extension distance of the second guide groove (e.g., the second guide groove 2413 of FIG. 6) of the first fastening groove 241.

In a state in which the rotation of the first strap 250 is completed, the first fastening pin 290a may move in the horizontal direction (e.g., the −x direction) toward the connecting groove 2412 along the second guide groove 2413 through the gap g. The first fastening pin 290a may move to the first guide groove 2411 through the connecting groove 2412, and may move in a vertical direction (e.g., −z direction) from the first guide groove 2411 to be separated from the first fastening groove 241. As a result, the first strap 250 may be separated from the pair of first lugs 240a as the first fastening pin 290a moves along the first fastening groove 241.

The user may press the upper side of the first pressing portion 256 (e.g., the upper portion 257 of the first strap 250) to rotate the first strap 250 in the counterclockwise direction, and then move the first fastening pin 290a along the first fastening groove 241 through the gap g between the housing 210 and the first strap 250 generated by the rotation of the first strap 250 to easily separate the first strap 250 from the pair of first lugs 240a.

The process of coupling the first strap 250 to the pair of first lugs 240a may correspond to the reverse order of the process of separating the first strap 250 from the pair of first lugs 240a described above. In a state in which the upper surface of the upper portion 257 of the first strap 250 faces one side surface of the housing 210, the first fastening pin 290a of the first strap 250 is inserted into the first fastening groove 241, and then the first fastening pin 290a is moved in the vertical/horizontal direction along the first fastening groove 241 so that the first fastening pin 290a is positioned at the end 241b of the first fastening groove 241. If the first fastening pin 290a reaches the end 241b of the first fastening groove 241, the first strap 250 is rotated clockwise. The upper surface of the upper portion 257 of the first strap 250 may contact one side surface of the housing 210 by the rotation of the first strap 250, and at least a portion of the upper portion 257 of the first strap 250 may be deformed toward the first pressing portion 256 by a reaction force caused by the contact with the housing 210. If the rotation of the first strap 250 is completed, the deformed portion of the upper portion 257 of the first strap 250 may be restored again, and thus the one end 250a of the first strap 250 comes in tight contact with one side surface of the housing 210, so that coupling of the first strap 250 to the pair of first lugs 240a may be completed.

FIG. 13 is a cross-sectional view taken along line A-A of FIG. 5.

FIG. 14 is a cross-sectional view taken along line E-E of FIG. 13.

FIG. 15 is a partial cross-sectional view illustrating that a strap is mounted to a lug of a housing in an electronic device according to an embodiment.

Referring to FIGS. 13 to 15, in an embodiment, a first fastening groove (e.g., the first fastening groove 241 of FIG. 2C) may be formed in one side surface of a pair of first lugs (e.g., the pair of first lugs 240a of FIG. 2A). The first fastening groove 241 may include a first guide groove (e.g., the first guide groove 2411 of FIG. 6), a connecting groove (e.g., the connecting groove 2412 of FIG. 6), or a second guide groove (e.g., the second guide groove 2413 of FIG. 6).

According to an embodiment, a first pinhole 2414 may be disposed at an end of the second guide groove 2413. In an embodiment, the first pinhole 2414 may be recessed from the recess surface of the second guide groove 2413 so that the depth of the groove is deeper than the depth of the second guide groove 2413.

According to an embodiment, a first pin (e.g., the first pin 292 of FIG. 4A) or a second pin (e.g., the second pin 293 of FIG. 4A) of a first fastening pin (e.g., the first fastening pin 290a of FIG. 2B) moving along the second guide groove 2413 may be inserted into the first pin hole 2414. In an embodiment, the first pinhole 2414 may be configured to have a shape corresponding to the first pin 292 or the second pin 293 of the first fastening pin 290a.

If the first fastening pin 290a moves along the first fastening groove 241 and reaches the first pinhole 2414, the first pin 292 or the second pin 293 of the first fastening pin 290a may be inserted into the first pinhole 2414 to indirectly inform the user that the coupling of the first strap 250 is completed.

If the first fastening pin 290a is seated in the first pinhole 2414, the movement of the first fastening pin 290a toward the second guide groove 2413 is limited due to the depth difference of the groove between the first pinhole 2414 and the second guide groove 2413. Therefore, even when the first strap 250 does not contact one side surface of the housing 210, easy separation of the first strap 250 from the pair of first lugs 240a may be reduced unless a separate external force is applied to the first strap 250.

FIG. 16 is a cross-sectional view taken along line C-C of FIG. 6.

FIG. 17 is a see-through view illustrating a strap (e.g., the straps 250 and 260 of FIG. 2A) is mounted to a lug (e.g., the lugs 240a and 240b of FIG. 2A) of a housing (e.g., the housing 210 of FIG. 2A) in an electronic device (e.g., the electronic device 200 of FIG. 2A) according to an embodiment.

Referring to FIGS. 16 and 17, in an embodiment, a first fastening groove (e.g., the first fastening groove 241 of FIG. 2C) may be formed in one side surface of a pair of first lugs (e.g., the pair of first lugs 240a of FIG. 2A).

The first fastening groove 241 may include a first guide groove (e.g., the first guide groove 2411 of FIG. 6), a connecting groove (e.g., the connecting groove 2412 of FIG. 6), or a second guide groove 2413a (e.g., the second guide groove 2413 of FIG. 6).

According to an embodiment, the second guide groove 2413a may extend in a horizonal direction (e.g., the x direction) from the connecting groove 2412. In an embodiment, the second guide groove 2413a may form a second straight section that is a path along which the first fastening pin 290a inserted into the first fastening groove 241 moves. In an embodiment, the second guide groove 2413a may be recessed from one side surface of the pair of first lugs 240a so that the depth of the groove gradually increases toward the second direction. In an embodiment, the second guide groove 2413a may be recessed from one side surface of the pair of first lugs 240a so that the recess surface is formed to be inclined with respect to the second direction (e.g., the x direction).

In the process in which the first fastening pin 290a moves from the end of the second guide groove 2413a to the connecting groove 2412, the movement of the first fastening pin 290a is limited by the resistance generated when the first fastening pin 290a comes into contact with the recessed surface of the second guide groove 2413a processed to be inclined. Therefore, even when the first strap 250 does not come into contact with one side surface of the housing 210, easy separation of the first strap 250 from the pair of first lugs 240a may be reduced unless a separate external force is applied to the first strap 250.

According to an embodiment, an electronic device 200 may include a housing 210 having a pair of lugs 240a and 240b, whose inner surfaces face each other, provided on two opposite sides to be substantially symmetrical. The electronic device 200 may include a strap 250 or 260 configured to be fitted to the pair of lugs 240a and 240b provided in the housing 210 to be mounted or detachable. The electronic device 200 may include a fastening groove 241 connecting an open end 241a and a closed end 241b to have at least one bend is formed to face the inner surfaces of each of the pair of lugs 240a and 240b. In the electronic device 200, a fastening pin 290a or 290b may be provided near one end of the strap 250 or 260 to move along the fastening groove 241 when the strap 250 or 260 is mounted to or detached from the pair of lugs 240a and 240b. Here, one end portion 250a of the strap 250 or 260 provided with the fastening pin 290a or 290b may correspond to an end facing the housing when mounted to the housing, of two opposite ends provided in the strap 250 or 260.

According to an embodiment, the fastening pin 290a or 290b may have a structure having elasticity against pressing in two opposite directions.
