In some embodiments, the camera module (301) may be positioned at the bottom of the display (22) and may perform related functions (e.g., image capture) without the position of the camera module (301) being visually distinguishable (or exposed). For example, the camera module (301) may be positioned on the back of the display (22) or below or beneath the display (22) and may include a hidden display back camera (UDC (under display camera)). In some embodiments, the camera module (301) may be positioned aligned with a recess formed on the back of the display (22). A camera module (301) is positioned to overlap at least a portion of the screen (S) so as to acquire an image of an external subject without being visually exposed to the outside. In this case, a portion of the display (22) that overlaps at least a portion of the camera module (301) may have a different pixel structure and / or wiring structure compared to other areas. For example, a portion of the display (22) that overlaps at least a portion of the camera module (22) may have a different pixel density compared to other areas. The pixel structure and / or wiring structure formed in a portion of the display (22) that overlaps at least a portion of the camera module (301) can reduce light loss between the outside and the camera module (301). In some embodiments, pixels may not be placed in a portion of the display (22) that overlaps at least a portion of the camera module (301).In some embodiments, the camera module (301) may be implemented as a plurality of camera modules (e.g., dual camera module or triple camera module) having different attributes (e.g., angle of view) or functions. For example, the plurality of camera modules may include a plurality of camera modules including lenses having different angles of view, and the electronic device (2) may control the change of the angle of view of the camera module performed in the electronic device (2) based on the user's selection. The plurality of camera modules may include at least one of a wide-angle camera, a telephoto camera, a color camera, a monochrome camera, or an IR (infrared) camera (e.g., a TOF (time of flight) camera, a structured light camera).

In some embodiments, the optical sensor may be positioned at the bottom of the display (22) and may perform its related function without the position of the optical sensor being visually distinguishable (or exposed). For example, the optical sensor may be positioned on the back of the display (22) or below or beneath the display (22). In some embodiments, the optical sensor may be positioned aligned with a recess formed on the back of the display (22). The optical sensor may be positioned overlapping at least a portion of the screen (S) to perform a sensing function without being exposed to the outside. In this case, the portion of the display (22) that overlaps at least a portion with the optical sensor may have a different pixel structure and / or wiring structure compared to other areas. For example, the portion of the display (22) that overlaps at least a portion with the optical sensor may have a different pixel density compared to other areas. In some embodiments, the sensor module may include an ultrasonic sensor located below the display (22). A pixel structure and / or wiring structure formed in a portion of the display (22) that overlaps at least partially with the sensor module can reduce the loss when various forms of signals (e.g., light or ultrasound) associated with the sensor module pass between the outside and the sensor module. In some embodiments, multiple pixels may not be placed in a portion of the display (22) that overlaps at least partially with the sensor module.

The plate (410) may be formed integrally with the first side wall (421), the second side wall (422), the third side wall (423), and / or the fourth side wall (424), and may comprise the same material (e.g., polymer or metal material). The first side wall (421) may be rotatably connected to the second housing (212) (see FIG. 2). For example, the first side wall (421) may include a recess (421a), a first hinge arm (421b), and / or a second hinge arm (421c). The recess (421a) may be formed between the first hinge arm (421b) and the second hinge arm (421c). A portion of the second housing (212) (see FIG. 2) may be located in a recess (421a) and may be rotatably hinged to the first hinge arm (421b) and the second hinge arm (421c).

[0069] According to one embodiment, the first housing (211) may include a first opening (51), a plurality of second openings (521, 522), a plurality of third openings (53), a plurality of fourth openings (54), and / or a plurality of fifth openings (55).

A plurality of third openings (53) may be formed in the third side wall (423). A plurality of fourth openings (54) may be formed in the fourth side wall (424). A plurality of third openings (53) and a plurality of fourth openings (54) may be arranged symmetrically with respect to the recess (421a) of the first side wall (421) when viewed from above the plate (410) (e.g., in the -z axis direction). In one embodiment, the first opening (51) may be an air intake port of a heat dissipation structure through which external air flows into (or is sucked into) the internal space of the first housing (211), and a plurality of second openings (52), a plurality of third openings (53), and / or a plurality of fourth openings (54) may be air outlet ports of a heat dissipation structure through which air is discharged from the internal space of the first housing (211) to the outside. In some embodiments, the first opening (51) may be implemented as an air outlet port of a heat dissipation structure through which air is discharged from the internal space of the first housing (211) to the outside. A plurality of fifth openings (55) may be formed in the plate (410).Multiple buttons of the keyboard (23) can be positioned in multiple fifth openings (55) and exposed to the outside.

[0070] According to one embodiment, the heat dissipation structure may include a first blower (551) and / or a second blower (552) in relation to an air intake (e.g., a first opening (51)) and an air discharge (e.g., a plurality of second openings (52), a plurality of third openings (53), or a plurality of fourth openings (54)). The first blower (551) and the second blower (552) may be located inside the first housing (211) to cause air flow. The first blower (551) or the second blower (552) may include, for example, a fan or a cooling fan. The first blower (551) and the second blower (552) may be arranged so as to be substantially symmetrical to each other with respect to the first opening (51) when viewed from above the first surface (201). Due to the flow of air by the first blower (551) and the second blower (552), a pressure difference may occur between the inside of the first housing (211) and the outside of the first housing (211), and as a result, outside air (external air) may be introduced (or sucked) into the inside of the first housing (211) through the first opening (51). Due to forced convection by the first blower (551) and the second blower (552), the air sucked through the first opening (51) receives heat emitted from at least one component and then flows into the air intake of the first blower (551) and the second blower (552), and can be discharged through the air discharge of the first blower (551) and the second blower (552). The first blower device (551) may include, for example, a first air discharge section corresponding to one or more second openings (521) and a second air discharge section corresponding to a plurality of third openings (53).The second blower (552) may include a third air discharge section corresponding to one or more second openings (522) and a fourth air discharge section corresponding to a plurality of fourth openings (54).

The third heat conducting member (562) may be located in the second air discharge section of the first blower (551) corresponding to a plurality of third openings (53) of the first housing (211). By conduction, where heat flows from a high-temperature section to a low-temperature section, heat emitted from at least one component may be transferred from the first heat conducting member to the second heat conducting member (561) via the fourth heat conducting member, and from the first heat conducting member to the third heat conducting member (562) via the fifth heat conducting member. The first heat-conducting member may include, for example, a heat spreader in the form of a patch placed on a printed circuit board (57). The fourth heat-conducting member or the fifth heat-conducting member may include a heat pipe or a vapor chamber.

Convective heat transfer, which is a method of energy transfer between a solid surface and a gas, may be applied between the third heat-conducting member (562) and the air, thereby allowing heat to be discharged to the outside through a plurality of third openings (53). Due to forced convection by the first blower (551), convective heat transfer performance between the second heat-conducting member (561) and the air, and convective heat transfer performance between the third heat-conducting member (562) and the air can be secured. The heat dissipation structure may include a second heat-conducting structure (or a second heat transfer structure) connected to the second blower (552). The second heat conduction structure can be implemented in correspondence with one or more second openings (522) and a plurality of fourth openings (54) in substantially the same manner as the first heat conduction structure connected to the first blower (551).

[0072] According to one embodiment, the heat dissipation structure may include a link structure (or link assembly) (6) located inside the first housing (211). The link structure (6) may be connected to a cover (25), and the cover (25) may open and close a first opening (51) (e.g., an air intake) by the link structure (6). The link structure (6) may be driven independently or under the control of a processor (e.g., the processor (120) of FIG. 1). In one embodiment, the link structure (6) may be driven based on a temperature detected inside the first housing (211) or heat emitted from at least one component within the first housing (211).

[0073] According to various embodiments, the cover (25) and the link structure (6) connected to the cover (25) may be positioned corresponding to an air intake or air outlet formed at various locations of the electronic device (2), not limited to the illustrated embodiments. For example, the cover (25) and the link structure (6) may be positioned corresponding to an air intake or air outlet formed at various locations, such as a first side (205) (see FIG. 4) or a first side wall (421) (see FIG. 4) of the electronic device (2). In various embodiments, the electronic device comprising the cover (25) and the link structure (6) corresponding to the air intake or air outlet may be implemented as a foldable electronic device of various forms, not limited to the illustrated examples.

[0074] FIG. 6 is a plan view of a link structure (6) in a closed state of a cover (25) in one embodiment (see FIG. 5). FIG. 7 is an enlarged view of the portion indicated by the reference numeral 'C' in FIG. 6 in one embodiment. FIG. 8 is a perspective view of the portion indicated by the reference numeral 'C' in FIG. 6 in one embodiment.

FIG. 10 is a side view of a part of the link structure (6) when viewed in the +x axis direction of the portion indicated by the reference numeral 'C' in FIG. 6 in one embodiment.

[0075] Referring to FIGS. 6, 7, 8, and 9, in one embodiment, the link structure (6) may include an actuator (60), a first link (61), a second link (62), a third link (63), and / or a hook structure (64).

[0076] According to one embodiment, power output from the actuator (60) can be transmitted to the third link (63) through the first link (61) and the second link (62), and the cover (25) connected to the third link (63) can be switched from a closed state (see FIG. 5) to an open state (see FIG. 4). The first link (61) can transmit force or motion between the actuator (60) and the second link (62). The second link (62) can transmit force or motion between the first link (61) and the third link (63). The actuator (60) can be driven based on the temperature detected inside the first housing (211) (see FIG. 5) or heat emitted from at least one part inside the first housing (211). For example, when the temperature detected inside the first housing (211) or the amount of heat emitted from at least one part inside the first housing (211) is above a threshold value, the actuator (60) can move the first link (61) in a first direction (e.g., +x axis direction).

[0077] According to one embodiment, the actuator (60) may be driven by itself without an electrical signal based on the temperature detected inside the first housing (211) (see FIG. 5) or heat emitted from at least one part inside the first housing (211). For example, the actuator (60) may generate power to move the first link (61) in a first direction (e.g., +x axis direction) using a bimetal that deforms in response to temperature.

[0078] According to some embodiments, the actuator (60) may generate power using an electrical signal. The actuator (60) may be driven under the control of a processor (e.g., the processor (120) of FIG. 1). For example, the actuator (60) may be implemented to generate power transmitted to the first link (61) using a motor. The actuator (60) may generate power to move the first link (61) in a first direction (e.g., +x axis direction) using a gear drive drivenly connected to the motor. In another example, the actuator (60) may be implemented to generate power transmitted to the first link (61) using a solenoid. The solenoid may include, for example, a coil and a plunger positioned corresponding to the coil, and may generate mechanical movement of the plunger when current is supplied to the coil.

[0079] According to one embodiment, the actuator (60) may be placed in a first housing (211) (see FIG. 5) or in a bracket (e.g., a support structure) located inside the first housing (211). The bracket may contribute to the durability or rigidity of the electronic device (2) as a frame structure that contributes to enabling the first housing (211) to withstand a load. The bracket (211) may be connected to the first housing (211) or formed integrally with the housing (211). For example, various components (see FIG. 5), such as a keyboard (23), a touchpad (24), a printed circuit board (57), a first blower (551), a second blower (552), or a link structure (6), may be placed in the bracket using various fastening methods, such as bolt fastening.

[0080] According to one embodiment, the first link (61) may be drivenly connected to the actuator (60) and the second link (62). The first link (61) may transmit power output from the actuator (60) to the second link (62). The first link (61) may include, for example, a shaft connecting the actuator (60) and the second link (62). Depending on the power transmitted from the actuator (60), the first travel distance and the first travel speed at which the first link (61) moves in a first direction (e.g., +x axis direction) may vary.

[0081] According to one embodiment, the link structure (6) may further include a support structure (not shown) that allows the first link (61) to move substantially in a first direction and prevents it from being separated from the link structure (6). The support structure may be disposed on the back surface of, for example, the plate (410) of the first housing (211) (see FIG. 4). In another example, the plate (410) may be formed to include the support structure.

[0082] According to one embodiment, the second link (62) may be drivenly connected to the first link (61) and the third link (63). When the first link (61) is moved in a first direction (e.g., +x axis direction) by power output from the actuator (61), the second link (62) may transmit power in a second direction (e.g., +y axis direction) perpendicular to the first direction corresponding to the first distance traveled by the first link (61). For example, when the first link (61) is moved in a first direction due to power output from the actuator (60), the transmission of force or motion between the first link (61) and the second link (62) may cause the second link (62) to move a part connected to the third link (63) (e.g., the second support structure (82)) in a second direction that is not parallel to the first direction. In one embodiment, the second direction may be orthogonal to the first direction. Depending on the first movement distance and first movement speed at which the first link (61) is moved in the first direction (e.g., +x axis direction), the second movement distance and second movement speed at which the part of the second link connected to the third link (63) (e.g., second support structure (82)) is moved in the second direction (e.g., +y axis direction) may vary.

[0083] According to one embodiment, the second link (62) is implemented based on a resilient structure (or elastic structure) and can be elastically connected to the first link (61) and the third link (63). For example, the resilient structure of the second link (62) can contribute to a stable motion transition based on an elastic effect between the first link (61) and the third link (63) in a change of state of the cover (25) (e.g., transition between a closed state and an open state, or transition between open states of different open angles). In one embodiment, when the first link (61) is moved in a first direction (e.g., +x axis direction) by a first movement speed and a first movement distance, the elastic structure of the second link (62) may cause the part of the second link (62) connected to the third link (63) (e.g., second support structure (82)) to be moved in a second direction (e.g., +y axis direction) by a second movement speed slower than the first movement speed and a second movement distance smaller than the first movement distance. In one embodiment, the second link (62) may include a shaft (70), a first support structure (81), a second support structure (82), a first elastic member (91), and / or a second elastic member (92).

[0084] According to one embodiment, the shaft (70) is in the form of a rod extending from one end (71) to the other end (72) in a second direction (e.g., +y axis direction) that is not parallel to the first direction (e.g., +x axis direction), and can transmit power in the second direction. When the first link (61) is moved in the first direction (e.g., +x axis direction), the shaft (70) can be moved in a second direction (e.g., +y axis direction) that is not parallel to the first direction. In one embodiment, the first link (61) may include a first inclined portion (611), and the one end (71) of the shaft (70) may include a second inclined portion (711) corresponding to the first inclined portion (611). Due to the interaction utilizing friction between the first inclined section (611) and the second inclined section (711), the first linear motion (or first translational motion) in which the first link (61) moves in a first direction can be converted into a second linear motion (or second translational motion) in which the shaft (70) moves in a second direction. In one embodiment, the first inclined section (611) and the second inclined section (711) may have inclined surfaces of the same angle of inclination corresponding to each other. Due to the interaction between the first inclined section (611) and the second inclined section (711) caused by the angle of inclination of the first inclined section (611) and the angle of inclination of the second inclined section (711), the first linear motion in which the first link (61) moves in a first direction can be converted into a second linear motion in which the shaft (70) moves in a second direction. Since the first inclined section (611) and the second inclined section (711) have inclined surfaces of the same angle of inclination that correspond to each other, the generation of friction noise or dust can be reduced. In some embodiments (not shown), the first inclined section (611) may be implemented as a structure in which a curved end or a rotating member such as a roller is rotatably arranged corresponding to the second inclined section (711).Interference between the first inclined section (611) and the second inclined section (711) can prevent the shaft (70) from deviating from the link structure (6) in a direction opposite to the second direction (e.g., the -y-axis direction). In some embodiments, to reduce friction between the first inclined section (611) and the second inclined section (711), a lubricant (e.g., grease) may be interposed between the first inclined section (611) and the second inclined section (711). In some embodiments, to reduce friction between the first inclined section (611) and the second inclined section (711), the surface of the first inclined section (611) and / or the surface of the second inclined section (711) may be coated with a lubricant.

[0085] According to some embodiments, without the first link (61), the actuator (60) may be implemented to move the shaft (70) of the second link (62) in a second direction (e.g., +y axis direction).

[0086] According to one embodiment, the first support structure (or first support member) (81) may be coupled to the first housing (211) (see FIG. 5) or to a bracket located inside the first housing (211). In another example, the first support structure (81) may be formed integrally with the first housing (211) or the bracket. In one embodiment, the first support structure (81) may include a first bottom portion (811) and a first side wall portion (812) coupled to the first housing (211) or the bracket. In one embodiment, the first bottom portion (811) may include a plate (e.g., a first bottom plate) that is substantially parallel to a first direction (e.g., the +x axis direction) and a second direction (e.g., the +y axis direction). The first side wall portion (812) may extend in a direction perpendicular to the first bottom portion (811) (e.g., +z axis direction). The first side wall portion (812) may be located between the plate (410) (see FIG. 4) of the first housing (211) and the first bottom portion (811). The first side wall portion (812) may include a first side wall (801), a second side wall (802), and / or a third side wall (803). The first side wall (801) may be perpendicular to the second direction (e.g., +y axis direction). The second side wall (802) may extend from one end of the first side wall (801), and the third side wall (803) may extend from the other end of the first side wall (801). The second side wall (802) and the third side wall (803) are located on opposite sides with a space between them and may be parallel to the second direction (e.g., the +y axis direction). The first support structure (81) may include a first space (813) between the first bottom portion (811) and the first side wall portion (812).

[0087] According to one embodiment, a second support structure (or second support member) (82) may be located in a first space (813) of a first support structure (81). The second support structure (82) may be connected to a third link (63). When the second support structure (82) moves in a second direction (e.g., +y-axis direction) in the first space (813), the third link (63) may cause the cover (25) (see FIG. 5) to open with respect to the first opening (51) (see FIG. 5). The second support structure (82) may include a shape corresponding to the first space (813) so that it can slide in the first space (813) substantially parallel to the second direction without wobbling. For example, the second support structure (82) may move linearly or translationally parallel to the second direction. In one embodiment, the second support structure (82) may include a second bottom portion (821) and a second side wall portion (822) extending from the second bottom portion (821). The second bottom portion (821) may include a plate (e.g., a second bottom plate) that faces and is substantially parallel to the first bottom portion (811) of the first support structure (81). The second side wall portion (822) may include a fourth side wall (804), a fifth side wall (805), and / or a sixth side wall (806). The fourth side wall (804) may face and be parallel to the first side wall (801) of the first support structure (81). The fifth side wall (805) may extend from one end of the fourth side wall (804), and the sixth side wall (806) may extend from the other end of the fourth side wall (804). The fifth side wall (805) may face and be parallel to the second side wall (802) of the first support structure (81). The sixth side wall (806) may face and be parallel to the third side wall (803) of the first support structure (81). The second support structure (82) may include a second space portion (823) between the second bottom portion (821) and the second side wall portion (822).

[0088] According to one embodiment, to reduce friction between the first support structure (81) and the second support structure (82), a lubricant (e.g., grease) may be interposed between the first support structure (81) and the second support structure (82). In some embodiments, to reduce friction between the first support structure (81) and the second support structure (82), the surface of the first support structure (81) and / or the surface of the second support structure (82) may be coated with a lubricating coating. In some embodiments, to reduce friction between the first support structure (81) and the second support structure (82), a sliding structure using various rolling members, such as a roller, may be implemented between the first support structure (81) and the second support structure (82).

[0089] According to one embodiment, the second support structure (82) may include a first slider (or first protrusion) (S1) that extends from the fifth side wall (805) in a direction perpendicular to the second direction (e.g., +x axis direction) and protrudes from the fifth side wall (805). The second support structure (82) may include a second slider (or second protrusion) (S2) that extends from the sixth side wall (806) in another direction perpendicular to the second direction (e.g., -x axis direction) and protrudes from the sixth side wall (806). The first slider (S1) and the second slider (S2) may be aligned in a direction perpendicular to the second direction (e.g., +x axis direction). The first support structure (81) may include a first guide hole (e.g., a first slit) (H1) formed in the second side wall (802) corresponding to the first slider (S1). The first support structure (81) may include a second guide hole (e.g., a second slit) (H2) formed in the third side wall (803) corresponding to the second slider (S2). The first guide hole (H1) and the second guide hole (H2) may be formed symmetrically with respect to the shaft (70) or the center line (E) of the shaft (70). The first guide hole (H1) and the second guide hole (H2) may be formed corresponding to the movement path of the second support structure (82). The first slider (S1) may be positioned in the first guide hole (H1). The second slider (S2) may be positioned in the second guide hole (H2). The first guide hole (H1) corresponding to the first slider (S1) and the second guide hole (H2) corresponding to the second slider (S2) may contribute to enabling the second support structure (82) to move stably in a straight line relative to the first support structure (81).The first slider (S1) and the first guide hole (H1), or the second slider (S2) and the second guide hole (H2) may limit the distance the second support structure (82) moves relative to the first support structure (81). The first slider (S1) and the first guide hole (H1), or the second slider (S2) and the second guide hole (H2) may contribute to enabling the second support structure (82) to move relative to the first support structure (81) without being separated from the first support structure (81). In order to enable the first slider (S1) to be positioned in the first guide hole (H1) and the second slider (S2) to be positioned in the second guide hole (H2) when combining the first support structure (81) and the second support structure (82), the first support structure (81) may include an opening (817a) extending from the first guide hole (H1) and an opening (817b) extending from the second guide hole (H2).

[0090] According to some embodiments, the first slider (S1) and the first guide hole (H1) may contribute to preventing the second side wall (802) of the first support structure (81) and the fifth side wall (805) of the second support structure (82) from rubbing against each other, or to reducing the area of ​​friction between them. The second slider (S2) and the second guide hole (H2) may contribute to preventing the third side wall (803) of the first support structure (81) and the sixth side wall (806) of the second support structure (82) from rubbing against each other, or to reducing the area of ​​friction between them.

[0091] According to some embodiments, the first slider (S1) and the first guide hole (H1), and the second slider (S2) and the second guide hole (H2) may contribute to preventing the first bottom portion (811) of the first support structure (81) and the second bottom portion (821) of the second support structure (82) from rubbing against each other, or to reducing the area of ​​friction between them.

[0092] According to some embodiments, in order to reduce the friction between the first slider (S1) and the first support structure (81) and the friction between the second slider (S2) and the first support structure (81), a lubricant (e.g., grease) may be interposed between the first slider (S1) and the first support structure (81), and between the second slider (S2) and the first support structure (81). In some embodiments, in order to reduce the friction between the first slider (S1) and the first support structure (81), the surface of the first slider (S1) or the surface of the first guide hole (H1) may be coated with a lubricant. In some embodiments, in order to reduce the friction between the second slider (S2) and the first support structure (81), the surface of the second slider (S2) or the surface of the second guide hole (H2) may be coated with a lubricant. In one embodiment, the first slider (S1) is formed in a shape having a curved portion corresponding to the surface of the first guide hole (H1) (e.g., a circular cylinder shape) to reduce friction with the first support structure (81). The second slider (S2) is formed in a shape having a curved portion corresponding to the surface of the second guide hole (H2) (e.g., a circular cylinder shape) to reduce friction with the first support structure (81). In some embodiments, to reduce friction between the first slider (S1) and the first support structure (81), a rolling member or a rotating member, such as a roller or a bearing, may be disposed on the first slider (S1). In some embodiments, to reduce friction between the second slider (S2) and the first support structure (81), a rolling member or a rotating member, such as a roller or a bearing, may be disposed on the second slider (S2).

[0093] According to one embodiment, the second slider (S2) of the second support structure (82) can be connected to the third link (63). The link structure (6) can transmit power from the second link (62) to the third link (63) through the second slider (S2).

[0094] According to one embodiment, the shaft (70) may be positioned across the second space portion (823) of the second support structure (82). One end (71) of the shaft (70) may protrude out of the second support structure (82) corresponding to the first inclined portion (611) of the first link (61). The other end (72) of the shaft (70) may protrude out of the second support structure (82). The fourth side wall (804) of the second support structure (82) may include, for example, a second notch (826) where the shaft (70) is positioned. The first side wall (801) of the first support structure (81) may include, for example, a first notch (816) where the shaft (70) is positioned. The first notch (816) may be a space in which a second portion (720) of a shaft (70) penetrating a first elastic member (e.g., a compression spring) (91) located in the first space (813) is disposed on the first side wall (801). One end (not shown) of the first elastic member (91) may be supported by the first side wall (801) including the first notch (816). The second notch (826) may be a space in which a second portion (720) of a shaft (70) penetrating a second elastic member (e.g., a compression spring) (92) located in the second space (823) is disposed on the fourth side wall (804). One end (not shown) of the second elastic member (92) may be supported by the fourth side wall (804) including the second notch (826).

[0095] According to some embodiments, one end (not shown) of the first elastic member (91) may be fixed to the first notch (816). For example, one end of the first elastic member (91) may be inserted into the first notch (816) and fixed to the first notch (816). A structure in which one end of the first elastic member (91) is fixed to the first notch (816) can prevent over-movement of the first elastic member (910). In some embodiments, one end (not shown) of the second elastic member (92) may be fixed to the second notch (826). For example, one end of the second elastic member (92) may be inserted into the second notch (826) and fixed to the second notch (826). A structure in which one end of the second elastic member (92) is fixed to the second notch (826) can prevent over-movement of the second elastic member (92).

[0096] According to some embodiments, a through hole may be formed in place of the first notch (816) or the second notch (826) through which the shaft (70) can pass.

[0097] According to one embodiment, in order to prevent the shaft (70) from being separated from the second support structure (82) in the +z axis direction, the second support structure (82) may include extensions (827) (e.g., anti-detachment parts) that extend from the fifth side wall (805) and / or the sixth side wall (806) and may cause interference with the shaft (70).

[0098] According to one embodiment, the shaft (70) may include a first part (710) including one end (71) and a second part (720) including the other end (72). The second elastic member (92) may be located in the second space (823) of the second support structure (82). The second elastic member (92) may be located between the first part (710) of the shaft (70) and the fourth side wall (804) of the second support structure (82). The second elastic member (92) may be, for example, a compression spring. The second part (720) of the shaft (70) may be located through the second elastic member (92). The second part (720) of the shaft (70) may be in the shape of a circular cylinder corresponding to the internal space of the second elastic member (92), which is, for example, implemented as a compression spring. In some embodiments, the second portion (720) of the shaft (70) may be formed as a cylinder having various different cross-sectional shapes. The first portion (710) of the shaft (70) may include at least a partially corresponding shape in the second space (823) so that it can slide in the second space (823) of the second support structure (820) without wobbling and substantially parallel to the second direction (e.g., +y axis direction). For example, the shaft (70) may move linearly or translationally parallel to the second direction. The first portion (710) of the shaft (70) may have a cross-sectional shape different from that of the second portion (720), and a step portion (732) may be formed between the first portion (710) and the second portion (720). The stepped portion (732) between the first portion (710) and the second portion (720) can serve as a second support portion that supports one side of the second elastic member (92), and hereinafter, the stepped portion (732) may be referred to as the 'second support portion'. In one embodiment, the second elastic member (92) can apply a force to the second support structure (82) to move the shaft (70) in a direction opposite to the second direction (e.g., -y-axis direction).When the second support structure (82) is moved in a second direction (e.g., +y axis direction) and the distance between the second support portion (732) (or first portion (710)) of the shaft (70) and the fourth side wall (804) of the second support structure (82) is reduced, the second elastic member (92) can be compressed. In some embodiments, the second elastic member (92) is not limited to a compression spring and can be implemented in various other forms. In some embodiments, the second elastic member (92) may be positioned between the second support portion (732) of the shaft (70) and the fourth side wall (804) of the second support structure (82), but may not be penetrated by the second portion (720) of the shaft (70).

[0099] According to some embodiments, to reduce friction between the shaft (70) and the second support structure (82), a lubricant (e.g., grease) may be interposed between the first part (710) of the shaft (70) and the second support structure (82). In other embodiments, to reduce friction between the shaft (70) and the second support structure (82), the surface of the first part (710) and / or the surface of the second support structure (82) may be coated with a lubricant. In other embodiments, to reduce friction between the shaft (70) and the second support structure (82), a sliding structure using various rolling members, such as rollers, may be implemented between the first part (710) and the second support structure (82).

[0100] According to one embodiment, the second portion (720) of the shaft (70) may include a first support portion (731) facing the fourth side wall (804) of the second support structure (70). The first support portion (731) may be located between the first side wall (801) of the first support structure (81) and the fourth side wall (804) of the second support structure (70). Interference between the first support portion (731) of the shaft (70) and the fourth side wall (804) of the second support structure (82) may prevent the shaft (70) from moving in a direction opposite to the second direction (e.g., the -y-axis direction). The first elastic member (91) may be located in the first space portion (813) of the first support structure (81). The first elastic member (91) may be positioned between the first support portion (731) of the shaft (70) and the first side wall (801) of the first support structure (81). The first elastic member (91) may be, for example, a compression spring. The second portion (720) of the shaft (70) may be positioned through the first elastic member (91). In some embodiments, the first elastic member (91) may not be limited to a compression spring and may be implemented in various other forms. In some embodiments, the first elastic member (91) may be positioned between the first side wall (801) of the first support structure (81) and the fourth side wall (804) of the second support structure (82), but may not be penetrated by the second portion (720) of the shaft (70). The first elastic member (91) can apply a force to move the second support structure (82) to the first support structure (81) in a direction opposite to the second direction (e.g., -y-axis direction). When the shaft (70) is moved in the second direction (e.g., +y-axis direction) and the distance between the first support portion (731) of the shaft (70) and the first side wall (801) of the first support structure (81) is reduced, the first elastic member (91) can be compressed. In some embodiments, the portion of the second portion (720) of the shaft (70) that is positioned through the first elastic member (91) may be omitted.In this case, the first notch (816) of the first support structure (81) may be omitted.

[0101] According to one embodiment, when the first slider (S1) of the second support structure (82) is positioned at one end of the first guide hole (H1) of the first support structure (81) and is in a state of interference with the first support structure (81) so that it is no longer moved in a direction opposite to the second direction (e.g., -y-axis direction), the cover (25) may be in a closed state. The second slider (S2) of the second support structure (82) connected to the third link (63) may be positioned at one end of the second guide hole (H2) of the first support structure (81) in the closed state of the cover (25) so that it is no longer moved in a direction opposite to the second direction and is in a state of interference with the first support structure (81). In some embodiments, the second slider (S2) connected to the third link (63) may be in a state where it does not interfere with the first support structure (81) with respect to movement in a direction opposite to the second direction while the cover (25) is closed.

[0102] According to some embodiments, when the second slider (S2) connected to the third link (63) is positioned at one end of the second guide hole (H2) and is in a state of interference with the first support structure (81) so that it is no longer moved in a direction opposite to the second direction (e.g., -y-axis direction), the cover (25) may be in a closed state. In this case, the first slider (S1) may be in a state where it is not in interference with the first support structure (81) regarding movement in a direction opposite to the second direction while the cover (25) is closed. In some cases, the first slider (S1) and the first guide hole (H1) may be omitted.

[0103] According to one embodiment, the second support structure (82) may include a third guide hole (e.g., a third slit) (H3) formed in the fifth side wall (805). The second support structure (82) may include a fourth guide hole (e.g., a fourth slit) (H4) formed in the sixth side wall (806). The first part (710) of the shaft (70) may include a third slider (or third protrusion) (S3) located in the third guide hole (H3). The first part (710) of the shaft (70) may include a fourth slider (or fourth protrusion) (S4) located in the fourth guide hole (H4). The third guide hole (H3) and the fourth guide hole (H4), or the third slider (S3) and the fourth slider (S4) may be arranged symmetrically with respect to the center line (E) of the shaft (70). The third guide hole (H3) and the fourth guide hole (H4) may be formed corresponding to the movement path of the second support structure (82) with respect to the shaft (70). When the force that narrows the distance between the first part (710) of the shaft (70) and the fourth side wall (804) of the second support structure (82) does not act in response to the elasticity of the second elastic member (92), the third slider (S3) of the shaft (70) may be positioned at one end of the third guide hole (H3) and may be formed in a state of interference with the second support structure (82) so that it is no longer moved in a direction opposite to the second direction. When the force that narrows the distance between the first part (710) of the shaft (70) and the fourth side wall (804) of the second support structure (82) does not act in response to the elasticity of the second elastic member (92), the fourth slider (S4) of the shaft (70) may be positioned at one end of the fourth guide hole (H4) and may be formed in a state of interference with the second support structure (82) so that it is no longer moved in a direction opposite to the second direction.

[0104] According to one embodiment, the second elastic member (92) may have a greater elastic force than the first elastic member (91). When the shaft (70) is moved in a second direction (e.g., the +y axis direction), the first elastic member (91) may be compressed, and the second elastic member (92), which has a greater elastic force than the first elastic member (91), may not be substantially compressed. When the shaft (70) is moved in the second direction, the second support structure (82), which is elastically supported on the shaft (70) using the second elastic member (92), may be moved in the second direction together with the shaft (70). The first slider (S1) and the first guide hole (H1), or the second slider (S2) and the second guide hole (H2), and the second support structure (82) can limit the distance moved relative to the first support structure (81), thereby limiting the elastic force on the first elastic member (91) and the second elastic member (92) when the cover (25) is switched between an open state and a closed state, or when the cover (25) is switched between open states at different open angles.

[0105] According to one embodiment, the hook structure (64) may include a first hook (641), a second hook (642), and / or a hook support (643). The first hook (641) and the second hook (642) may extend from the hook support (643). The hook support (643) may be formed in a ring shape (e.g., a square ring shape) into which the first support structure (81) can be inserted, for example. The hook support (643) may be coupled with the first support structure (81). In some embodiments, the hook support (643) and the first support structure (81) may be formed integrally. The first hook (641) and the second hook (642) may be arranged symmetrically with respect to the center line (E) of the shaft (70). When the distance between the first support portion (731) of the shaft (70) and the first side wall (801) of the first support structure (81) is reduced so that the first elastic member (91) is compressed, and the second support structure (82) is moved in a direction opposite to the second direction (e.g., -y-axis direction), the second elastic member (92) can be compressed. In one embodiment, when an external force is applied to the cover (25) connected to the third link (63) to forcibly switch it from an open state to a closed state, the second slider (S2) of the second support structure (82) connected to the third link (63) is moved in a direction opposite to the second direction, and the second elastic member (92) can be compressed. When an external force is applied to the cover (25) connected to the third link (63) to forcibly switch it from an open state to a closed state, the first slider (S1) or the second slider (S2) of the second support structure (82) may be in a state of interference with the first support structure (81) with respect to movement in a direction opposite to the second direction.When an external force is applied to the cover (25) connected to the third link (63) to forcibly switch it from an open state to a closed state, the part (901) where the fifth side wall (805) of the second support structure (82) and the third slider (S3) of the shaft (70) meet opens up, and a first hook fastening part in the form of a recess corresponding to the first hook (641) (e.g., see the first hook fastening part (1410) of FIG. 14) can be formed. The first hook (641), with one end connected to the hook support part (643), can be restored from a bent state like a cantilever and fastened to the first hook fastening part. When an external force is applied to the cover (25) connected to the third link (63) to forcibly switch it from an open state to a closed state, the part (902) where the sixth side wall (806) of the second support structure (82) and the fourth slider (S4) of the shaft (70) meet opens up, and a second hook fastening part in the form of a recess corresponding to the second hook (642) (e.g., see second hook fastening part (1420) in FIG. 14) can be formed. The second hook (642), with one end connected to the hook support part (643), can be restored from a bent state like a cantilever and fastened to the second hook fastening part. The first support structure (81) may include a first through-hole (or first through-hole) (818) formed in the second side wall (802) corresponding to the first hook (641), and a second through-hole (or second through-hole) (819) formed in the third side wall (803) corresponding to the second hook (642). The first hook (641) may pass through the first through-hole (818) and be fastened to the first hook fastening part, and the second hook (642) may pass through the second through-hole (819) and be fastened to the second hook fastening part. The first hook (641) connected to the first hook connecting part and the second hook (642) connected to the second hook connecting part can prevent the second support structure (82) connected to the third link (63) from moving in the second direction (e.g., +y axis direction), thereby maintaining the closed state of the cover (25).In some embodiments, one of the first hook (641) and the second hook (642), and one corresponding hook fastening part may be omitted.

[0106] According to one embodiment, a third link (63) (e.g., a cover support structure) may be connected to the cover (25). The third link (63) may include, for example, a foldable structure (or seesaw structure) capable of scissor action (e.g., contraction or elongation). The foldable structure may include a plurality of link elements and joints connecting the plurality of link elements. The third link (63) may include, for example, a first link element (631), a second link element (632), and / or a third link element (633). The cover (25) may include a front surface (251) that forms the outer surface of the electronic device (2) when closed, and a back surface (252) located opposite to the front surface (251). The front surface (251) may, for example, be substantially flat. In another example, the front surface (251) may include a curved surface. The cover (25) may include a support portion (253) in a shape protruding from the back surface (252). The first link element (631) may be coupled to the back surface (252) of the cover (25). For example, the first link element (631) may include a bolt fastening hole (6311) for bolt fastening with the cover (25). One end of the second link element (632) may be connected to the first link element (631), and the other end of the second link element (632) may be connected to the support portion (253) of the cover (25). In some embodiments, the first link element (631) and the second link element (632) may be formed integrally. The second element (632) may be positioned not parallel to the front surface (251) of the cover (25). One end of the third link element (633) can be rotatably connected to the second link element (632) by a joint (1002) at a position between one end and the other end of the second link element (632).The other end of the third link element (633) can be rotatably connected to the second slider (S2) of the second support structure (82). The joint (1001) between the support member (253) and the second link element (632) can be rotatably connected (or fixed) to the first support structure (81).

[0107] When the second support structure (82) including the second slider (S2) is moved in the second direction (e.g., +y axis direction), the cover (25) can be switched from a closed state to an open state due to the scissor action between the second link element (632) and the third link element (633).

[0108] According to one embodiment, the components included in the link structure (6) may be formed of a material (e.g., metal or engineering plastic) having stiffness or tolerance that does not substantially deform against the force acting during the state change of the cover (25) (e.g., transition between a closed state and an open state). This reduces the loss of motion transmitted between the components during the state change of the cover (25).

[0109] According to one embodiment, the link structure (6) may include another second link (65), another third link (66), and / or another hook structure (67) included in reference numeral 'D' shown in FIG. 6. The other second link (65) is drivenly connected to the first link (61) and may be implemented substantially symmetrically with respect to the second link (62) included in reference numeral 'C' with respect to the first link (61). The other third link (66) is drivenly connected to the other second link and cover (25) and may be implemented substantially symmetrically with respect to the third link (63) included in reference numeral 'C' with respect to the first link (61). The other hook structure (67) may be implemented substantially symmetrically with respect to the hook structure (64) included in reference numeral 'C' with respect to the first link (61). The second link (62) and the third link (63) included in the part indicated by the reference numeral 'C' apply force to one side of the cover (25), and the other link and the other third link included in the part indicated by the reference numeral 'D' apply force to the other side of the cover (25), so the cover (25) can be opened or closed stably. In some embodiments, the link structure (6) may be implemented in a plurality of forms including the first link (61), the second link (62), the third link (63), and the actuator (60), and the other link and the other third link included in the part indicated by the reference numeral 'D' may be omitted.

[0110] FIG. 11 is a plan view of a portion of the link structure (6) in a state change of the cover (25) (see FIG. 4 or 5) in one embodiment. FIG. 12 illustrates a cross-sectional structure of a portion of the link structure (6) in a state change of the cover (25) in one embodiment. FIG. 13 is a side view of a portion of the link structure (6) in an open state of the cover (25) in one embodiment.

[0111] Referring to FIG. 11, the reference numeral '1101' indicates a plan view of a part of the link structure (6) in the closed state of the cover (25), and the reference numeral '1102' indicates a plan view of a part of the link structure (6) in the open state of the cover (25). Referring to FIG. 12, the reference numeral '1201' indicates a cross-sectional structure of a part of the link structure (6) in the closed state of the cover (25), and the reference numeral '1202' indicates a cross-sectional structure of a part of the link structure (6) in the open state of the cover (25).

[0112] For example, the operation for the link structure (6) to switch the cover (25) from a closed state to an open state is as follows. The first link (61) can be moved a first distance (D1) in a first direction (e.g., +x axis direction) due to power transmitted from the actuator (60) (see FIG. 6). The shaft (70) can be moved a second distance (D2) in a second direction (e.g., +y axis direction) different from the first direction due to the interaction between the first link (61) and the shaft (70). The second elastic member (92) (e.g., a second compression spring) between the shaft (70) and the second support structure (82) can have a greater elastic force than the first elastic member (91) (e.g., a first compression spring) between the second support structure (82) and the first support structure (81). The second support structure (82) is elastically supported by a second elastic member (92) between the shaft (70) and the second support structure (82) and can be moved in a second direction by a second travel distance (D2). The first elastic member (91) can be compressed, and the second elastic member (92) may not be substantially compressed because it has a greater elastic force than the first elastic member (91). The second slider (S2) of the second support structure (82) connected to the third link (63) can be moved in a second direction by a second travel distance (D2), and the cover (25) can be switched from a closed state to an open state due to the interaction between the cover (25) and the third link (63). In one embodiment, the third link (63) can transmit power in a third direction (e.g., +z axis direction) perpendicular to both the first and second directions to switch the cover (25) from a closed state to an open state. The illustrated example may relate to the cover (25) being opened at a maximum angle (e.g., fully open state).Although not illustrated, the second distance (D2) by which the second support structure (82) including the second slider (S2) is moved in the second direction may vary depending on the first distance (D1) by which the first link (61) is moved in the first direction, and accordingly, the open angle of the cover (25) may vary. Depending on the open angle of the cover (25), the compressed state of the first elastic member (91) may vary. For example, when the open angle of the cover (25) is at the maximum angle, the compression ratio or compressive force of the first elastic member (91) may be at the maximum. As the first elastic member (91) begins to be compressed, the open angle of the cover (25) may increase. Depending on the first movement speed at which the first link (61) is moved in the first direction, the second movement speed at which the second support structure (82) including the second slider (S2) is moved in the second direction may vary, and accordingly, the speed at which the cover (25) opens may vary.

[0113] For example, the operation for the link structure (6) to switch the cover (25) from an open state to a closed state is as follows: The shaft (70) may be moved a second distance (D2) in a direction opposite to the second direction (e.g., -y-axis direction). The first link (61) may be moved a first distance (D1) in a direction opposite to the first direction (e.g., -x-axis direction) due to the interaction between the first link (61) and the shaft (70). The second support structure (82) may be supported by the shaft (70) and moved a second distance (D2) in a direction opposite to the second direction. A restoring force (or elastic force) that attempts to restore the first elastic member (91) from a compressed state to an uncompressed state may act on the movement of the shaft (70) and the second support structure (82). The second slider (S2) of the second support structure (82) connected to the third link (63) can be moved a second distance (D2) in a direction opposite to the second direction, and the cover (25) can be switched from an open state to a closed state due to the interaction between the cover (25) and the third link (63). In the closed state of the cover (25), the first elastic member (91) may be less compressed or substantially uncompressed than when the cover (25) is in an open state. While the cover (25) is switching from an open state to a closed state, the power output from the actuator (60) (see FIG. 6) may be substantially non-existent or may have a size that enables the first elastic member (91) to restore. Depending on the size of the power output from the actuator (60), the speed at which the cover (25) closes may vary.

[0114] FIG. 14 illustrates a cross-sectional structure of a part of a link structure (6) when, in one embodiment, the cover (25) (see FIG. 4 or 5) is forcibly switched from an open state to a closed state. FIG. 15 illustrates a part of the link structure (6) when, in one embodiment, the cover (25) is forcibly closed.

[0115] Referring to FIG. 14, reference numeral '1401' indicates a cross-sectional structure regarding a part of the link structure (6) when the cover (25) is open at the maximum angle (e.g., fully open), and reference numeral '1402' indicates a cross-sectional structure regarding a part of the link structure (6) when the cover (25) is forcibly closed. In one embodiment, the cover (25) may be forcibly closed by applying an external force to the cover (25). For example, when the electronic device (2) (see FIG. 2) is transitioned from an open state to a closed state, the cover (25) may be forcibly closed by the second housing (212). In the illustrated example, the cover (25) is forcibly transitioned from a fully open state to a closed state, but the cover (25) may be forcibly transitioned from an open state at an angle smaller than the fully open state to a closed state. When the cover (25) is forcibly switched from an open state at an open angle smaller than the fully open state to a closed state, it can be driven in substantially the same manner as when the cover (25) is forcibly switched from a fully open state to a closed state, except that the degree of compression of the first elastic member (91) is different. In one embodiment, when the cover (25) is forcibly switched from an open state to a closed state due to an external force, the second support structure (82) including the second slider (S2) connected to the cover (25) can be moved by a third travel distance (D3) in a direction opposite to the second direction (e.g., -y-axis direction). In one embodiment, the third travel distance (D3) may be substantially the same as the second travel distance (D2) of FIG. 11. In some embodiments, the third travel distance (D3) may be different from the second travel distance (D2) of FIG. 11. The second elastic member (92) (e.g., second compression spring) between the shaft (70) and the second support structure (82) can be compressed.When the cover (25) is forcibly switched from an open state to a closed state due to an external force, the first slider (S1) or the second slider (S2) of the second support structure (82) may be in a state of interference with the first support structure (81) with respect to movement in a direction opposite to the second direction.

[0116] According to one embodiment, when an external force is applied to the cover (25) connected to the third link (63) to forcibly switch it from an open state to a closed state, the part where the fifth side wall (805) of the second support structure (82) and the third slider (S3) of the shaft (70) come into contact opens up, and a first hook fastening part (1410) in the form of a recess corresponding to the first hook (641) can be formed. The first hook (641) can be restored from a bent state like a cantilever and fastened to the first hook fastening part (1410). When an external force is applied to the cover (25) connected to the third link (63) to forcibly switch it from an open state to a closed state, the part where the sixth side wall (806) of the second support structure (82) and the fourth slider (S4) of the shaft (70) meet opens up, and a second hook fastening part (1420) in the form of a recess corresponding to the second hook (642) can be formed. The second hook (642) can be restored from a bent state like a cantilever and fastened to the second hook fastening part (1420). The first hook (641) fastened to the first hook fastening part (1410) and the second hook (642) fastened to the second hook fastening part (1420) can prevent the second support structure (82) from moving in the second direction (e.g., +y axis direction) in response to the elastic force of the second elastic member (92) in a compressed state, and thus the closed state of the cover (25) can be maintained.

[0117] In one embodiment, the operation of the link structure (6) transitioning from the state of the cross-sectional structure indicated by reference numeral '1401' in FIG. 14 to the state of the cross-sectional structure indicated by reference numeral '1201' in FIG. 12 is, for example, as follows. When the electronic device (2) (see FIG. 2) transitions from an unfolded state to a folded state, the amount of heat emitted from at least one component within the first housing (211) can be reduced. For example, when the electronic device (2) transitions from an unfolded state to a folded state, the electronic device (2) can enter a low-power mode or a sleep mode, and at least one component may not be used, or the current consumption from at least one component may be smaller compared to the unfolded state. Accordingly, when the electronic device (2) transitions from an unfolded state to a folded state, the temperature detected inside the first housing (211) or the amount of heat emitted from at least one component within the first housing (211) can be reduced to below a threshold value. In this case, the power output from the actuator (60) (see FIG. 6) is substantially non-existent, or the first elastic member (91) may have a size that enables restoration, and thus the shaft (70) may be moved in a direction opposite to the second direction (e.g., -y direction) due to the elastic force of the first elastic member (91). When the shaft (70) is moved in a direction opposite to the second direction due to the elastic force of the first elastic member (91), the second elastic member (92) between the shaft (70) and the second support structure (82) may be restored as in the state of the cross-sectional structure shown in reference numeral '1201' of FIG. 12. The third slider (S3) of the shaft (70) may include a first inclined surface (1411), and the fourth slider (S4) of the shaft (70) may include a second inclined surface (1421).When the shaft (70) is moved in a direction opposite to the second direction due to the elastic force of the first elastic member (91), the first hook (641) may be bent in correspondence with the first inclined surface (1411) of the third slider (S3), and the second hook (642) may be bent in correspondence with the second inclined surface (1421) of the fourth slider (S4) of the shaft (70), and the first hook (641) and the second hook (642) may be arranged as in the state of the cross-sectional structure shown in reference numeral '1201' of FIG. 12.

[0118] FIG. 16 is a partial cross-sectional view (1600) of the actuator (60) of FIG. 6 in one embodiment.

[0119] Referring to FIG. 16, in one embodiment, the actuator (60) may output power to be transmitted to the first link (61) (see FIG. 6) using a bimetal that deforms in response to temperature. The actuator (60) may include, for example, a housing (1610), a shaft (1620), a plurality of bimetals (1631, 1632, 1633, 1634), a plurality of support members (1641, 1642, 1643, 1644), and / or an elastic member (1650). The plurality of bimetals (1631, 1632, 1633, 1634), the plurality of support members (1641, 1642, 1643, 1644), and / or the elastic member (1650) may be located within the housing (1610). A shaft (1620) may be positioned through a first opening (1611) of a housing (1610) as an element for transmitting power to a first link (61) (see FIG. 6). One end of the shaft (1620) may be positioned outside the housing (1610), and the other end of the shaft (1620) may be positioned inside the housing (1610). An elastic member (1650) may elastically support the shaft (1620) in a direction opposite to the first direction with respect to the housing (1610) (e.g., -x axis direction). The elastic member (1650) may include, for example, a compression spring, and the shaft (1620) may be positioned through the elastic member (1650). The elastic member (1650) may be positioned between the inner wall of the housing (1610) and a support (1621) formed at the end of the shaft (1620). A plurality of bimetals (1631, 1632, 1633, 1634) may be formed by stacking and bonding two types of thin metal plates with different coefficients of thermal expansion (e.g., the degree to which they expand or contract with a change in temperature) together. The plurality of bimetals (1631, 1632, 1633, 1634) may be deformed in response to heat above a specified temperature and may return to their original state at heat below a specified temperature.A plurality of bimetals (1631, 1632, 1633, 1634) may be arranged in a first direction (e.g., +x axis direction). A plurality of bimetals (1631, 1632, 1633, 1634) may be placed on a plurality of support members (1641, 1642, 1643, 1644). A plurality of support members (1641, 1642, 1643, 1644) may be positioned inside a housing (1610) so as to be movable in the first direction. A shaft (1620) may be placed in contact with a first bimetal (1631). A second bimetal (1632) may be placed in contact with a first support member (1641) on which the first bimetal (1631) is placed. The third bimetal (1633) may be positioned in contact with the second support member (1642) on which the second bimetal (1632) is positioned. The fourth bimetal (1634) may be positioned in contact with the third support member (1643) on which the third bimetal (1633) is positioned. Due to at least one bimetal among the plurality of bimetals (1631, 1632, 1633, 1634) that is deformed in response to heat, the travel distance and / or travel speed of the shaft (1620) connected to the first link (61) may vary. For example, if the first bimetal (1631) is deformed by heat as indicated by the virtual line (dotted line) pointed to by the reference numeral '1601', the first bimetal (1631) can press the shaft (1620) in the first direction, and the shaft (1620) can be moved in the first direction by a first displacement corresponding to the deformation of the first bimetal (1631). For example, if the second bimetal (1632) is deformed by heat as indicated by the virtual line (dotted line) pointed to by the reference numeral '1602', the second bimetal (1632) can press the first support member (1641) on which the first bimetal (1631) is placed in the first direction, and the shaft (1620) can be moved in the first direction by a displacement corresponding to the deformation of the second bimetal (1632).In the same way, when the third bimetal (1633) is deformed in response to heat, the deformed third bimetal (1633) can press the second support member (1642) in the first direction, and the shaft (1620) can be moved in the first direction by a displacement corresponding to the deformation of the third bimetal (1633). In the same way, when the fourth bimetal (1634) is deformed in response to heat, the deformed fourth bimetal (1634) can press the third support member (1643) in the first direction, and the shaft (1620) can be moved in the first direction by a displacement corresponding to the deformation of the fourth bimetal (1634). The number of bimetals and support members on which the bimetals are disposed may vary and is not limited to the illustrated examples. In some embodiments, the elastic member (1650) may be omitted.

[0120] According to one embodiment, any one of the plurality of bimetals (1631, 1632, 1633, 1634) may be deformed in response to heat above a first temperature, and any other of the plurality of bimetals (1631, 1632, 1633, 1634) may be deformed in response to heat above a second temperature different from the first temperature.

[0121] According to one embodiment, a first displacement in a first direction (e.g., +x axis direction) in which any one of the plurality of bimetals (1631, 1632, 1633, 1634) is deformed in response to heat may be substantially the same as a second displacement in a first direction in which any one of the plurality of bimetals (1631, 1632, 1633, 1634) is deformed in response to heat. In some embodiments, the first displacement or the second displacement may be different.

[0122] Although this document describes a heat dissipation structure using a laptop computer as an example, the heat dissipation structure according to the embodiments of this document can be applied to various other types of electronic devices.

[0123] According to one embodiment of the present document, an electronic device (e.g., electronic device (2) of FIG. 2) may include a housing (e.g., first housing (211) of FIG. 2) that includes an opening (e.g., first opening (51) of FIG. 2). The electronic device may include a cover (e.g., cover (25) of FIG. 2) that opens and closes the opening. The electronic device may include a link structure (e.g., link structure (6) of FIG. 6) connected to the cover, and the link structure may be located inside the housing. The link structure may include an actuator (e.g., actuator (60) of FIG. 6) that outputs power based on a temperature detected inside the housing. The link structure may include a first link (e.g., first link (61) of FIG. 6) that moves in the first direction by the power. The link structure may include a second link (e.g., the second link (62) of FIG. 6). The second link may transmit power in a second direction perpendicular to the first direction in response to the movement of the first link. The second link may be implemented as an elastic structure including a first spring (e.g., the first spring (91) of FIG. 7) and a second spring (e.g., the second spring (92) of FIG. 7) having different elastic forces. The link structure may include a third link (e.g., the third link (63) of FIG. 6). The third link may connect the second link and the cover. The third link may transmit power in a third direction perpendicular to the first direction and the second direction to switch the cover from a closed state to an open state.

[0124] According to one embodiment, the actuator (e.g., actuator (60) of FIG. 6) may include a bimetal that deforms in response to a temperature detected inside a housing (e.g., first housing (211) of FIG. 2), or may be electrically connected to a temperature sensor (e.g., sensor module (176) of FIG. 1) that is placed in the housing (e.g., first housing (211) of FIG. 2)) and detects the temperature. For example, the actuator (60) may output power based on a signal from the temperature sensor (e.g., sensor module (176) of FIG. 1).

[0125] According to one embodiment of the present document, the second link (e.g., the second link (62) of FIG. 6) may include a first support structure (e.g., the first support structure (81) of FIG. 8) disposed in or integrally formed with the housing (e.g., the first housing (211) of FIG. 5). The second link may include a second support structure (e.g., the second support structure (82) of FIG. 8) located in a first space portion (e.g., the first space portion (813) of FIG. 8) of the first support structure. The second support structure may be slidable parallel to the second direction with respect to the first support structure. The second support structure may be connected to the third link (e.g., the third link (63) of FIG. 8). The second link may include a shaft (e.g., shaft (70) in FIG. 8) positioned across a second space (e.g., second space (823) in FIG. 8) of the second support structure. The shaft may extend from one end (e.g., one end (71) in FIG. 8) corresponding to the first link to the other end (e.g., other end (72) in FIG. 8). The shaft may be slidable parallel to the second direction with respect to the second support structure. The first spring may be positioned in the first space by being penetrated by the shaft.
