[0200] According to one embodiment, the carrier (425) may include an inner carrier (4251) and an outer carrier (4252). The description of the inner carrier (4251) and the outer carrier (4252) may be substantially identical to the description of the inner carrier (3251) and the outer carrier (3252) described with reference to FIGS. 1 to 17.

[0201] According to one embodiment, the inner carrier (4251) may include a first body (4251a) and a protrusion (4251b). The description of the first body (4251a) and the protrusion (4251b) may be substantially identical to the description of the first body (3251a) and the protrusion (3251b) described with reference to FIGS. 1 to 17.

[0202] In one embodiment, the inner carrier (4251) may include an inner engaging portion (4251c) and a pin (4251d). The inner engaging portion (4251c) may protrude radially outwardly from the first body (4251a). The pin (4251d) may protrude from the inner engaging portion (4251c) toward the outer carrier (4252). The inner engaging portion (4251c) may include a plurality of inner engaging portions (4251c1, 4251c2) spaced apart from each other in the rotational direction of the inner carrier (4251). For example, the inner engaging portions (4251c) may include a first inner engaging portion (4251c1) and a second inner engaging portion (4251c2) spaced apart from each other.

[0203] According to one embodiment, the outer carrier (4252) may include a second body (4252a) and a rim portion (4252b). The description of the second body (4252a) and the rim portion (4252b) may be substantially identical to the description of the second body (3252a) and the rim portion (3252b) described with reference to FIGS. 1 to 17.

[0204] In one embodiment, the outer carrier (4252) may include a slit (4252c). The slit (4252c) may extend along the rotational direction of the inner carrier (4251). The slit (4252c) may include a first slit end (4252c1) and a second slit end (4252c2). A pin (4251d) may be movably inserted into the slit (4252c). The pin (4251d) may be movably positioned between the first slit end (4252c1) and the second slit end (4252c2). When the inner carrier (4251) rotates, the pin (4251d) may be caught by either the first slit end (4252c1) or the second slit end (4252c2). The pin (4251d) can push either the first slit end (4252c1) or the second slit end (4252c2). By engaging the pin (4251d) and the slit ends (4252c1, 4252c2), the inner carrier (4251) and the outer carrier (4252) can move together.

[0205] Due to the structure of the carrier (325, 425) according to the embodiment of the present disclosure, when an impact is applied to the electronic device (101), the impact force transmitted to the driving device (300) can be reduced. For example, since a gap (G) is formed between the inner engaging portion (3251c) and the outer engaging portion (3252c), when an impact is applied to the electronic device (101), the inner carrier (3251) and the outer carrier (3252) move relative to each other by the gap (G), so that the impact amount can be distributed during the time of the relative movement.

[0206] FIG. 19 is a diagram of an electronic device (101) according to one embodiment of the present disclosure. The components described with reference to FIG. 19 may be partially or entirely identical to the components described with reference to FIGS. 1 to 18. The components described with reference to FIG. 19 may be partially or entirely identical to the components described with reference to FIGS. 20 to 25.

[0207] According to one embodiment, the electronic device (101) may include a housing (2100) and a display (2030). The description of the housing (2100) and the display (2030) may be identical to the description of the housing (210) and the display (203) described with reference to FIGS. 1 to 4.

[0208] According to one embodiment, the housing (2100) may include a first housing (2010) and a second housing (2020) movably positioned relative to the first housing (2010). The second housing (2030) may be extendable in a first direction (SO) and retractable in a second direction (SI) relative to the first housing (2010). The display (2030) may include a first display area (2031) and a second display area (2032) that moves and folds or unfolds together with the first display area (2031).

[0209] According to one embodiment, the electronic device (101) according to the embodiment of FIG. 19 may include the driving device (300) described with reference to FIGS. 1 to 18. The driving device (300) may be disposed inside the housing (2100). The driving device (300) may move the second housing (2020).

[0210] The structure of the gears (e.g., the structure of the first, second, and third gears (321, 322, and 323)), the material of the gears (e.g., the material of the first, second, and third gears (321, 322, and 323)), and the structure of the carrier (325) (e.g., the structure of the inner carrier and the outer carrier (3251, 3252)) described with reference to FIGS. 9a to 19 can be applied to at least one of the first reduction device (3201) and the second reduction device (3202). For example, the structure of the gears (e.g., the structure of the first, second, and third gears (321, 322, 323)), the material of the gears (e.g., the material of the first, second, and third gears (321, 322, 323)), and the structure of the carrier (325) (e.g., the structure of the inner carrier and the outer carrier (3251, 3252)) may be applied to the first reduction device (3201) and may not be applied to the second reduction device (3202). For example, the structure of the gears (e.g., the structure of the first, second, and third gears (321, 322, 323)), the material of the gears (e.g., the material of the first, second, and third gears (321, 322, 323)) and the structure of the carrier (325) (e.g., the structure of the inner carrier and the outer carrier (3251, 3252)) can be applied to both the first reduction device (3201) and the second reduction device (3202).

[0211] An electronic device (101) according to an embodiment of the present disclosure includes a driving device (300) for moving a second housing (202) relative to a first housing (201). The driving device (300) includes an actuator (310) and a reduction device (320), and the reduction device (320) includes a gear assembly (324). The gear assembly (324) may include different types of gears, and the different types of gears may mesh with each other and rotate. When different types of gears mesh with each other and rotate, noise and vibration may occur due to friction at the part where the gears mesh. For example, when a sun gear (321) made of a metal material and a planet gear (322) made of a metal material mesh with each other, noise and vibration may occur due to the meshing of the sun gear (321) and the planet gear (322) made of the same metal material. Vibration generated in the driving device (300) is transmitted to the entire electronic device (101) through other structures arranged inside the housing (210), and causes vibration and noise in the entire electronic device (101). The electronic device (101) according to the embodiment of the present disclosure can reduce noise and vibration generated in the driving device (300) by forming the materials of the gears (321, 322, 323) differently at the portion where the gears (321, 322, 323) of the driving device (300) mesh with each other. Meanwhile, when the materials of some of the gears (321, 322, 323) are formed of a non-metallic material, the durability of the driving device (300) may be reduced. For example, wear of the planet gear (322) may occur at the portion where the planet gear (322) and the carrier (325) are in contact at the portion where the planet gear (322) and the carrier (325) are coupled. The electronic device (101) according to the embodiment of the present disclosure can increase the durability and lifespan of the planet gear (322) by arranging a metal ring (3228) at a portion where the planet gear (322) and the carrier (325) come into contact. Meanwhile, when some of the gears (321, 322, 323) are formed of a non-metallic material, the impact resistance of the driving device (300) may be reduced.For example, when an external impact is applied to the electronic device (101), the carrier (325) combined with the planet gear (322) may have its lifespan reduced by the impact force transmitted through the planet gear (322). The electronic device (101) according to the embodiment of the present disclosure configures the carrier (325) as an inner carrier (3251) and an outer carrier (3252), and forms a gap (G) between the inner engaging portion (3251c) of the inner carrier (3251) and the outer engaging portion (3252c) of the outer carrier (3252), so that when an external impact is applied to the electronic device (101), the impact amount is distributed during the relative movement time due to the relative movement of the inner carrier (3251) and the outer carrier (3252), thereby increasing the impact resistance of the carrier (325).

[0212] FIGS. 20 to 25 are drawings illustrating the effects of a driving device (300) according to an embodiment of the present disclosure. The components described with reference to FIGS. 20 to 25 may be partially or entirely identical to the components described with reference to FIGS. 1 to 19.

[0213] Referring to FIG. 20, the frequency due to gear engagement occurring in the first reduction device (first reduction section) (3201) of the driving device (300) may be approximately 656, 1313, 1969, 2625, 3281, 3938, 4594, 5250, 5907, 6563 Hz depending on the reduction ratio.

[0214] Referring to Fig. 21, the frequency band due to gear engagement occurring in the first reduction device (first reduction section) (3201) described above corresponds to the frequency range of relatively large noises occurring in the entire electronic device (101).

[0215] Referring to Fig. 22, it can be confirmed that the noise and vibration in the area (P1, P2, P3) where the driving device (300) is located in the electronic device (101) are greater than those in the surrounding area. Referring to Fig. 23, it can be confirmed that the tendencies of the noise diagram (L1) according to the frequency band generated in the electronic device (101) and the noise diagram (L2) according to the frequency band generated in the driving device (300) are substantially the same. In particular, it can be confirmed that the noise of the electronic device (101) and the noise of the driving device (300) increase with the same tendency in the frequency band of the M region.

[0216] Referring to FIG. 24, it can be confirmed that the noise generated in the embodiment (K) of the present disclosure in which the materials of the gears (321, 322, 323) of the driving device (300) are formed differently is reduced compared to the comparative embodiment (J) in which the materials of all gears of the driving device are formed identically.

[0217] Referring to FIGS. 20 to 24, the electronic device (101) according to the embodiment of the present disclosure can reduce noise and vibration transmitted by the driving device (300) to the entire electronic device (101) by differently configuring the materials of the gears (321, 322, 323) of the driving device (300).

[0218] Referring to FIG. 25, when an impact is applied to an electronic device according to a comparative example (U) including a carrier formed of only one part, it can be confirmed that the impact force (F1) applied to the carrier is greater than the impact force (F2) applied to the carrier (325) according to the embodiment (V) of the present disclosure when the same impact is applied. Compared to the comparative example, the carrier (325) according to the embodiment of the present disclosure has an impact resistance that is increased by the difference in impact force (D) even when the same impact is applied.

[0219] An electronic device includes a movable housing and a drive mechanism that moves the housing. The drive mechanism includes an actuator and different types of gears that transmit power generated by the actuator. The different types of gears mesh with each other and rotate. When the different types of gears mesh with each other and rotate, noise and vibration are generated at the meshing portion of the gears.

[0220] The problem to be solved in the present disclosure may be to reduce noise and vibration generated in electronic devices.

[0221] A problem to be solved in the present disclosure may be to increase the durability of an electronic device.

[0222] The problem to be solved in this disclosure is not limited to the problem mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.

[0223] Electronic devices according to various embodiments of the present disclosure can reduce noise and vibration caused by friction between gears by configuring the materials of gears included in a driving device differently.

[0224] An electronic device according to various embodiments of the present disclosure can increase the durability of a driving device by arranging gearing on the inside of a gear and configuring a carrier into two parts.
