Description

Electronic device including a vibration reduction structure

[0001] Embodiments of the present disclosure relate to an electronic device including a vibration reduction structure.

[0002] Electronic devices are being developed to become increasingly slimmer, increase rigidity, enhance design aspects, and differentiate their functional elements. Electronic devices are moving away from uniform rectangular shapes and are gradually transforming into various shapes. Electronic devices may have a deformable structure that allows for convenient portability and the use of a large-screen display. Electronic devices may include a rollable electronic device (e.g., a sliderable electronic device) capable of varying the display area of ​​a flexible display (e.g., a rollable display) through the support of housings that operate in a sliding manner relative to each other. The rollable electronic device may include a motor for automatically driving at least one housing relative to the other housing to vary the flexible display. The rollable electronic device may require an improved structure capable of reducing vibration and / or noise caused by motor driving.

[0003] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art related to the present disclosure.

[0004] The electronic device may include a rollable electronic device (e.g., a slideable electronic device) capable of inducing the expansion and / or reduction of the display area of ​​a flexible display (e.g., a rollable display, an expandable display, or a stretchable display) depending on the operating state. The rollable electronic device may include a first housing and a second housing movably coupled to each other. For example, the first housing and the second housing may operate slidably to each other and may support at least a portion of the flexible display, and the flexible display may be induced to have a first display area in a slide-in state and a second display area larger than the first display area in a slide-out state.

[0005] A rollable electronic device may include a motor (e.g., a motor) for automatically moving one housing relative to another housing. For example, the rollable electronic device may automatically perform retraction / extraction operations through a drive mechanism comprising a first gear (pinion gear) placed in one housing and rotated via a motor, and a second gear (rack gear) placed in the other housing and geared with the first gear. The housing in which the motor is placed may include a weak rigidity region having relatively weak rigidity compared to the surrounding area. The weak rigidity region may include a portion formed with a relatively thin thickness of the housing and / or a portion where the sidewall is removed to improve the placement efficiency of electronic components (e.g., a battery) placed in the relative housing in the retracted state.

[0006] In rollable electronic devices, vibrations may occur when the motor is driven, and these vibrations are amplified through the weak-stiffness region, which consequently increases the operating noise of the rollable electronic device and can reduce reliability.

[0007] Various embodiments of the present disclosure may provide an electronic device including a vibration reduction structure capable of reducing vibration caused by the driving of a motor.

[0008] According to various embodiments, an electronic device including a vibration reduction structure that can help reduce noise by reducing vibration can be provided.

[0096] According to various embodiments, the fourth side wall (2211) and the sixth side wall (2213) of the second housing (220) may be omitted at least partially. This is because, in the retracted state, the fourth side wall (2211) and the sixth side wall (2213) that overlap with the first housing (210) may restrict the expansion of the area of ​​the battery (B). Accordingly, the second housing (220) may help expand the capacity of the battery (B) by omitting a portion of the fourth side wall (2211) and the sixth side wall (2213) that overlap with the battery (B) in the retracted state of the electronic device, and by positioning it to overlap up to the vicinity of the motor (260). Through this structure, the placement efficiency of the battery (B) or surrounding electrical components can be improved, but when the motor (260) is driven, the part of the second support plate (222) from which the side walls (2211, 2213) have been removed acts as a direct vibration source, increasing the vibration, and the problem of increased driving noise due to the increased vibration may occur.

[0097] An electronic device (200) according to exemplary embodiments of the present disclosure may have a vibration reduction structure (e.g., vibration reduction structure (NR) of FIG. 8a) (e.g., noise reduction structure) formed on a second support plate (222) along at least a portion of the edge (e.g., edge) of a motor fixing part (e.g., motor fixing part (229) of FIG. 8a) to which a motor (260) is fixed, and may include at least one slit (e.g., slit (228) of FIG. 8a) (e.g., slot, opening, through hole, or recess), so that vibrations generated from the motor (260) may not be directly transmitted to the area where the side walls (2211, 2213) are removed. For example, vibrations generated from the motor (260) are diverted through surrounding side walls having relatively strong rigidity (e.g., high rigidity area or first area) and then indirectly transmitted to an area where the side walls (2211, 2213) are removed (e.g., weak rigidity area or second area), thereby reducing the vibrations and thus reducing the noise.

[0098] FIG. 5a is a cross-sectional view of an electronic device viewed along line 5a-5a of FIG. 2a according to various embodiments of the present disclosure. FIG. 5b is a cross-sectional view of an electronic device viewed along line 5b-5b of FIG. 3a according to various embodiments of the present disclosure.

[0099] In describing the electronic device (200) of FIG. 5a and FIG. 5b, the same reference numerals have been assigned to components that are substantially identical to those of the electronic device (200) of FIG. 4, and a detailed description thereof may be omitted.

[0100] Referring to FIGS. 5a and 5b, the electronic device (200) may include a first housing (210) having a first space (2101), a second housing (220) having a second space (2201), a support member (240) connected to the second housing (220) and received at least partially into the first space (2101) in an inverted state, a flexible display (230) positioned to receive support from at least a part of the support member (240) and at least a part of the second housing (220), a rack gear (263) fixed to the first space (2101) and extended into the second space (2201), and a motor (260) including a pinion gear (262) positioned in the second space (2201) and geared with the rack gear (263). In one embodiment, the motor (260) can automatically move the second housing (220) relative to the first housing (210) in the withdrawal direction (direction ①) or the insertion direction (direction ②) through the gear engagement of the pinion gear (262) and the rack gear (263). In some embodiments, the first housing (210) may be automatically moved from the second housing (220) in the withdrawal direction (direction ②) or the insertion direction (direction ①) by changing the arrangement of the motor (260) and the rack gear (263). In one embodiment, the first housing (210) may include a first rear cover (213) coupled to a first side member (211) and a first support plate (212) extending from the first side member (211). In one embodiment, the second housing (220) may include a second rear cover (223) coupled to a second side member (221).

[0101] According to various embodiments, a portion of the second housing (220) may be accommodated in the first space (2101) of the first housing (210) in the retracted state of the electronic device (200) (state of FIG. 5a). In one embodiment, at least a portion of the flexible display (230) may be accommodated in the first space (2101) by bending it together with a support member (240) so as not to be seen from the outside. In this case, the flexible display (230) may have a first display area (e.g., a display area corresponding to the first portion (230a) of FIG. 3a) visually exposed to the outside.

[0102] According to various embodiments, at least a portion of the second housing (220) may be transitioned to an out-of-the-box state in which it is moved at least partially out of the first housing (210) along a first direction (direction ①) by driving a motor (260). In one embodiment, the flexible display (230) may be exposed so that at least a portion of the portion inserted into the first space (2101) can be seen from the outside by moving together with a support member (240) while being supported by a support bracket (225) in the out-of-the-box state of the electronic device (200) (state of FIG. 5b). In this case, the flexible display (230) may have a second display area (e.g., a display area including the first portion (230a) and the second portion (230b) of FIG. 3a) that is extended beyond the first display area exposed to the outside. In some embodiments, the rack gear (263) may be placed in the second housing (220), and the motor (260) including the pinion gear (262) may be placed in the first housing (210).

[0103] FIGS. 6a and 6b are drawings illustrating the inlet and outlet states of an electronic device including a motor according to various embodiments of the present disclosure.

[0104] FIGS. 7a and 7b are partial perspective views of an electronic device illustrating the arrangement positions of a rack gear in an out-of-circuit state and an in-circuit state according to various embodiments of the present disclosure.

[0105] Referring to FIGS. 6a to 7b, the electronic device (200) may include a first housing (210) having a first space (2101), a second housing (220) having a second space (2201), a support member (240) connected to the second housing (220) and received at least partially into the first space (2101) in an inverted state, a flexible display (230) positioned to receive support from at least a part of the support member (240) and at least a part of the second housing (220), a rack gear (263) fixed to the first space (2101) and extended into the second space (2201), and a motor (260) including a pinion gear (262) positioned in the second space (2201) and geared with the rack gear (263).

[0106] According to various embodiments, the electronic device (200) may include a motor (260) that is placed in a second space (2201) of a second housing (220) and electrically connected to a first substrate (251) placed nearby. In one embodiment, the motor (260) may be powered by at least one of a battery (B) placed in a first space (2101) of a first housing (210) or an additional battery (B1) placed in a second space (2201) of a second housing (220). In one embodiment, the motor (260) may include a motor body (261) and a pinion gear (262) as a first gear rotatably coupled to the motor body (261). In one embodiment, the pinion gear (262) may be positioned to be supported by a motor bracket (260a) that is fixed to a motor fixing part (e.g., motor fixing part (229) of FIG. 8a) of the second space (2201). In one embodiment, the motor body (261) may be positioned to be supported by a motor bulkhead (222a) that extends to a specific height from the support plate.

[0107] According to various embodiments, the electronic device (200) may include a rack gear (263) (e.g., a rack or connecting member) as a second gear having a length in the sliding direction (e.g., the y-axis direction) of the second housing (220), which is fixed at one end to the first housing (210) (e.g., the support bracket (225) of FIG. 4) and is at least partially received into the second space (2201) of the second housing (220) according to the inlet / outlet operation. In one embodiment, the rack gear (263) may be gear-coupled with a pinion gear (262). In one embodiment, the rack gear (263) may be positioned to be movably supported on at least a part of the motor bracket (260a) so as to help maintain a stable gear-coupled state during operation.

[0108] According to various embodiments, the motor (260) and the motor bracket (260a) may be positioned to overlap at least a portion of the first housing (210) in the retracted state. In one embodiment, the motor (260) and the motor bracket (260a) may be positioned to overlap at least a portion of the first housing (210) in the withdrawn state. In one embodiment, at least a portion of the fourth side wall (2211) and the sixth side wall (2213) of the second housing (220) may be positioned to overlap with the first housing (210) in the retracted state. In one embodiment, at least a portion of the fourth side wall (2211) and the sixth side wall (2213) of the second housing (220) may be positioned not to overlap with the first housing (210). In one embodiment, the portion (e.g., weak rigidity region) where the fourth side wall (2211) and the sixth side wall (2212) of the second housing (220) are removed may be positioned to overlap with the first housing (210) in the withdrawn state.

[0109] According to various embodiments, the electronic device (200) may include a slit (228) as a vibration reduction structure (NR) (e.g., noise reduction structure) formed in a second support plate (222) along at least a portion of the edge (e.g., edge) of a motor fixing part (e.g., motor fixing part (229) of FIG. 8a) to which the motor (260) is fixed. In one embodiment, vibrations generated from the motor (260) may not be directly transmitted to the surrounding area and the area where the side walls (2211, 2213) are removed through at least a partial separation structure in which the motor fixing part (229) is cut off by the slit (228). For example, vibrations generated from the motor (260) can be reduced and noise reduced by being diverted through surrounding side walls (e.g., fourth side wall (2211)) having relatively strong rigidity and then indirectly transmitted to an area where the side walls (2211, 2213) have been removed (e.g., weak rigidity area or second area).

[0110] FIG. 8a is a configuration diagram of a second housing according to various embodiments of the present disclosure.

[0111] Referring to FIG. 8a, the second housing (220) may include a side member (221) comprising first, second, and third side walls (2211, 2212, 2213) and a second support plate (222) extending into a second space (2201) from at least some of the first, second, and third side walls (2211, 2212, 2213). In one embodiment, the second housing (220) may include a motor body fixing part (261a) formed on at least a part of the second support plate (222) to which the motor body (261) of the motor (260) is fixed, and a motor fixing part (229) (e.g., a part of the second support plate (222)) to which a motor bracket (260a) supporting a pinion gear (262) is fixed. In one embodiment, the second housing (220) may include a motor bulkhead (222a) that extends to a specific height along the edge of the motor body fixing part (261a) in the second support plate (222).

[0112] According to various embodiments, the second housing (220) may include a slit (228) as a vibration reduction structure (NR) positioned to at least partially surround the edge (e.g., edge) of the motor fixing part (229). In one embodiment, the slit (228) may be formed in such a way that it penetrates from one side of the second support plate (222) to the other side. In one embodiment, the slit (228) may be formed in such a way that it surrounds the remaining edge of the motor fixing part (229), except for a portion (221c) facing the fourth side wall (2211). Thus, the motor fixing part (229) may be positioned to be connected to the fourth side wall (2211) through the slit (228).

[0113] According to various embodiments, the second housing (220) may include a first region, a high-rigidity region (221a) (e.g., a high-rigidity structure), and a second region extending from the high-rigidity region (221a) and having relatively weak rigidity, a weak-rigidity region (221b) (e.g., a weak-rigidity structure). In one embodiment, the high-rigidity region (221a) may include side walls (2211, 2212, 2213) having relatively high rigidity. In one embodiment, the high-rigidity region (221a) may include a region having a relatively thick thickness in the second support plate (222). In one embodiment, the high-rigidity region (221a) may include a support structure such as a bulkhead, bracket, or bushing formed from the second support plate (222). In one embodiment, the weak rigidity region (221b) may include a portion of the support plate (222) from which the side walls (2211, 2213) have been removed. In one embodiment, the weak rigidity region (221b) may include a region having a relatively thin thickness. For example, the distinction between the illustrated regions (221a, 221b) is merely an example, and the high rigidity region (221a) and the weak rigidity region (221b) may exist in various forms. In one embodiment, the motor fixing part (229), which is part of the second support plate (222), may be at least partially supported by a portion of the fourth side wall (2211). In one embodiment, the thickness of the side walls (e.g., the fourth side wall (2211)) may be set to be thicker than the thickness of the weak rigidity region (221b) (e.g., the corresponding region of the second support plate (222) that overlaps with the battery (B) placed in the first housing (210) in the retracted state).

[0114] According to various embodiments, the motor body fixing part (261a) and the motor fixing part (229) may be positioned in the high-rigidity region (221a). In some embodiments, at least a portion of the motor body fixing part (261a) and the motor fixing part (229) may be positioned in the low-rigidity region (221b). In one embodiment, at least a portion of the slit (228) may be positioned between the high-rigidity region (221a) and the low-rigidity region (221b), in the high-rigidity region (221a) and / or the low-rigidity region (221b). In one embodiment, the fourth side wall (2211) and the sixth side wall (2213) may extend from the high-rigidity region (221a) to a portion of the low-rigidity region (221b). In this case, the weak rigidity region (221b) may include a corresponding portion of the second support plate (222) in which the fourth and sixth side walls (2211, 2213) are omitted.

[0115] FIG. 8b is a configuration diagram of a second housing with a motor arranged therein according to various embodiments of the present disclosure. FIG. 8c is a partial cross-sectional view of the second housing shown along line 8c-8c of FIG. 8b according to various embodiments of the present disclosure. FIG. 8d is a partial cross-sectional view of the second housing shown along line 8d-8d of FIG. 8b according to various embodiments of the present disclosure.

[0116] Referring to FIGS. 8b through 8d, the electronic device (200) may include a motor (260) fixed to a motor body fixing part (e.g., the motor body fixing part (261a) of FIG. 8a) and a motor fixing part (229) formed in a second space (2201) of a second housing (220). For example, the motor body (261) of the motor (260) may be positioned to be supported by a motor bulkhead (222a) in the motor body fixing part (261a), and a motor bracket (260a) supporting a pinion gear (262) may be fixed to the motor fixing part (229). In one embodiment, the motor bracket (260a) may be fixed to the motor fixing part (229) through a fastening member such as a screw. In some embodiments, the motor bracket (260a) may be fixed to the motor fixing part (229) through a bonding process such as bonding, taping, or welding (e.g., ultrasonic welding or thermal welding).

[0117] According to various embodiments, the height (h) of the motor bulkhead (222a) may be set to be substantially the same as the installation height of the motor body (261). In some embodiments, the height (h) of the motor bulkhead (222a) may be set to be partially lower than the installation height of the motor body (261). In one embodiment, the motor body (261) may be positioned to have a specific gap (g) so as not to come into contact with the motor bulkhead (222a), thereby helping to reduce vibration during operation. For example, a positioning structure having such a gap (g) may be achieved by fixing a pinion gear (262) (e.g., a gear assembly) to be supported by a motor bracket (260a). In some embodiments, a cushioning member (not shown) may be interposed in at least a portion of the gap (g) located between the motor bulkhead (222a) and the motor body (261). For example, the cushioning member may include elastic materials such as sponge, rubber, urethane, or silicone.

[0118] According to various embodiments, when the motor (260) is driven, the phenomenon of vibrations generated from the motor (260) being directly transmitted to the weak-rigidity region (221b) through the slit (228) can be reduced. In one embodiment, the vibrations generated from the motor (260) are first transmitted to the fourth side wall (2211), which is a high-rigidity region extending from the motor fixing part (229), and then indirectly transmitted to the weak-rigidity region (221b), thereby reducing the vibrations that could be amplified by being directly transmitted to the weak-rigidity region, and thus helping to reduce noise.

[0119] FIGS. 9a and 9b are drawings comparing the vibration displacement of a second housing by region in a driving frequency band of a motor with or without a slit according to various embodiments of the present disclosure.

[0120] Referring to FIGS. 9a and 9b, if there is no slit (228) placed near the motor fixing part (229) (e.g., the drawing of FIG. 9a), it can be seen that vibrations generated from the motor (260) are transmitted generally to the weak rigidity region (221b) as well as the high rigidity region (221a) of the second housing (220). On the other hand, if a slit (228) is placed near the motor fixing part (229), vibrations generated from the motor (260) are blocked by the slit (228), thereby reducing the degree of vibration generated in the second housing (220).

[0121] This may mean that if vibrations generated from the motor (260) are preferentially guided to the fourth side wall (2211), which is a high-rigidity region (221a), through the slit (228) surrounding the edge of the motor fixing part (229), it may help reduce the operating noise of the electronic device by inducing a reduction in vibrations generated throughout the second housing (220).

[0122] FIG. 10a is a graph comparing the noise frequency characteristics of a second housing with and without a slit according to various embodiments of the present disclosure.

[0123] Referring to FIG. 10a, when the slit (228) is placed around the motor fixed part (229) compared to when the slit (228) is not placed, the noise frequency (level) caused by vibration generated when the motor (260) is driven is improved by about 3 dB or more in most areas (e.g., areas 1001 and 1002), excluding some areas (e.g., area 1003), based on a frequency band of about 0.5KHz to 4KHz that is included in the actual audible frequency band.

[0124] FIG. 10b is a graph comparing the frequency response characteristics of a second housing with or without a slit according to various embodiments of the present disclosure.

[0125] Referring to FIG. 10b, it can be seen that when a slit (228) is placed around the motor fixed part (229) (e.g., graph 1004) compared to when a slit (228) is not placed around the motor fixed part (229) (e.g., graph 1005), the peak value of the noise frequency due to vibration of the second housing (220) corresponding to the main rotational speed of the motor (e.g., 5280 RPM and 6000 RPM) is low-shifted, thereby reducing noise amplification. For example, when the motor operates at 5280 RPM, if the slit (228) is not placed around the motor fixed part (229), the noise frequency due to vibration of the second housing (220) has a peak value of about 1680 Hz, but if the slit (228) is placed around the motor fixed part (229), the noise frequency due to vibration of the second housing (220) has a relatively low peak value of about 1525 Hz and is low shifted, so it can be confirmed that noise amplification is reduced through the placement of the slit (228).

[0126] FIG. 11a is a drawing showing the bottom surface of a motor bracket according to various embodiments of the present disclosure. FIG. 11b is a partial cross-sectional view of a second housing in which a motor is placed according to various embodiments of the present disclosure.

[0127] Referring to FIGS. 11a and 11b, the electronic device (200) may further include a cushioning member (270) disposed between the motor bracket (260a) and the motor fixing part (229) of the second housing (220). In one embodiment, the cushioning member (270) may include an elastic tape member. In one embodiment, the cushioning member (270) may be attached to the back surface of the motor bracket (260a) via an adhesive member (271) (e.g., PSA). In some embodiments, the cushioning member (270) may be configured not to be attached to the motor fixing part (229) but to maintain only a contact state. In one embodiment, the cushioning member (270) may include a compressible cushioning material (e.g., an elastic material or an elastic material) such as a sponge or poron.

[0128] FIG. 12 is a graph showing the frequency response characteristics of a second housing according to the presence or absence of a cushioning member disposed between a motor bracket and a motor fixing part according to various embodiments of the present disclosure.

[0129] According to various embodiments, even though vibration characteristics are improved through a slit (228) formed around the motor fixing part (229) and the noise frequency (level) is generally reduced by the improved vibration characteristics, as shown in FIG. 10a, a frequency band of about 4KHz (e.g., area 1003 of FIG. 10a) may be an exception.

[0130] Referring to FIG. 12, when a slit (228) is formed around the motor fixing part (229) and a cushioning member (270) is added between the motor bracket (260a) and the motor fixing part (229), it can be seen that the noise frequency (level) is improved not only in the frequency band of about 4KHz (e.g., area 1203) but also across the audible frequency band of FIG. 10a (e.g., area 1201).

[0131] FIGS. 13a to 13e are configuration diagrams of a second housing including a vibration reduction structure according to various embodiments of the present disclosure.

[0132] In describing the second housing (220) of FIGS. 13a to 13e, the same reference numerals have been used for components that are substantially identical to the second housing (220) of FIG. 8a, and a detailed description thereof may be omitted.

[0133] Referring to FIG. 13a, the second housing (220) may include a slit (228-1) as a vibration reduction structure (NR) arranged to surround at least a portion of the edge of the motor fixing part (229). In one embodiment, the slit (228-1) may be formed in an 'L' shape extending vertically from the portion facing the weak rigidity part (221b), excluding the portion (221c) facing the fourth side wall (2211) of the edge of the motor fixing part (229). For example, the minimum arrangement of the slit (228-1) may help reinforce the rigidity of the second support plate (222).

[0134] Referring to FIG. 13b, the second housing (220) may include a slit (228-2) positioned to surround at least a portion of the edge of the motor fixing part (229). In one embodiment, the slit (228-2) may be formed in a '—' shape only on the portion facing the weak rigidity part (221b), excluding the portion (221c) facing the fourth side wall (2211) of the edge of the motor fixing part (229). For example, the minimum placement of the slit (228-2) may help reinforce the rigidity of the second support plate (222).

[0135] Referring to FIG. 13c, the second housing (220) may include a plurality of slits (228-3) as a vibration reduction structure (NR) arranged to surround at least a portion of the edge of the motor fixing part (229). In one embodiment, the plurality of slits (228-3) may include a first slit (228a), a second slit (228b), a third slit (228c), and a fourth slit (228d), with the first slit (228a), the second slit (228b), the third slit (228c), and the fourth slit (228d) being arranged sequentially, excluding the portion (221c) facing the fourth side wall (2211) of the edge of the motor fixing part (229). In one embodiment, the plurality of slits (228-3) may be formed as fewer than four or more than five. For example, the spaced arrangement of the plurality of slits (228-3) may help reinforce the rigidity of the second support plate (222).

[0136] Referring to FIG. 13d, the second housing (220) may include a slit (228) as a vibration reduction structure (NR) arranged to surround at least a portion of the edge of the motor fixing part (229). In one embodiment, the slit (228) may be formed excluding the portion (221c) of the edge of the motor fixing part (229) facing the fourth side wall (2211). In one embodiment, the slit (228) may be filled with an injection molded material (272). In one embodiment, the injection molded material (272) may include a polymer. For example, the arrangement of the slit (228) filled with the injection molded material (272) may help reinforce the rigidity of the second support plate (222).

[0137] Referring to FIG. 13e, the second housing (220) may include a motor fixing part (229) formed through an injection molded part (272) made of a material different from the second support plate (222). In one embodiment, the injection molded part (272) may include a material with weaker rigidity (e.g., low hardness material) than the second support plate (222). For example, if the second support plate (222) is a metal material, the motor fixing part may be formed of a polymer (e.g., PC, polycarbonate).

[0138] In some embodiments, some of the plurality of slits may be arranged to overlap at least partially when the second support plate (222) is viewed from above. In this case, the shape and / or size of some of the overlapping slits may differ from one another.

[0139] In some embodiments, the thickness of the slit may be set differently for each region. For example, the thickness of the slit may be set through the difference in thickness of the second support plate (222) forming the high-rigidity region (221a) and the low-rigidity region (221b). In this case, the thickness (e.g., depth) of the slit may be set such that the thickness in the direction of the high-rigidity region (221a) (e.g., y-axis direction) and the thickness in the direction of the low-rigidity region (221b) (e.g., -y-axis direction) are different from each other. In this case, the thickness of the slit may be set such that the thickness in the direction of the high-rigidity region (221a) (e.g., y-axis direction) is thicker than the thickness in the direction of the low-rigidity region (221b) (e.g., -y-axis direction).

[0140] FIG. 14 is a configuration diagram of a second housing including a motor fixing part according to various embodiments of the present disclosure.

[0141] In describing the second housing (220-1) of FIG. 14, the same reference numerals have been used for components that are substantially identical to the second housing (220) of FIG. 8a, and a detailed description thereof may be omitted.

[0142] Referring to FIG. 14, the second housing (220-1) may include a motor fixing part (229) positioned in the center along the width direction (e.g., x-axis direction). In this case, the pinion gear (e.g., pinion gear (262) of FIG. 8b) and the rack gear (e.g., rack gear (263) of FIG. 8b) are positioned to cross the center of the electronic device (200) along the sliding direction (e.g., ±y-axis direction) of the second housing (220), thereby reducing the increase in driving resistance force due to the eccentric placement of the motor (e.g., motor (260) of FIG. 8a) during sliding operation, and thus reducing the current consumption of the motor.

[0143] According to various embodiments, the second housing (220-1) may include a slit (228-4) as a vibration reduction structure (NR) formed at a position facing the weak rigidity region (221b) of the edge of the motor fixing part (229). In one embodiment, the slit (228-4) may be formed in a straight shape (e.g., a straight line shape) having a specific length. In one embodiment, the second housing (220-1) may include a bulkhead (2223) extending from the motor fixing part (229) to the fourth sidewall (2211) and / or the sixth sidewall (2213) as a high rigidity structure. In one embodiment, the bulkhead (2223) may be arranged in a manner connected to a motor bulkhead (222a) arranged to surround at least a portion of the motor (260). Accordingly, the phenomenon of vibrations generated from the motor (260) being directly transmitted to the weak-rigidity region (221b) by the slit (228-4) is reduced, and by being transmitted indirectly to the fourth side wall (2211) and / or the sixth side wall (2213) through the partition (2223), which can help reduce noise in the electronic device.

[0144] FIG. 15a is a configuration diagram of an electronic device including a motor according to various embodiments of the present disclosure. FIG. 15b is a configuration diagram of a second housing of FIG. 15a according to various embodiments of the present disclosure. FIG. 15c is a partial perspective view of a second housing with a rack gear arranged thereon according to various embodiments of the present disclosure.

[0145] In describing the electronic device (200-1) of FIGS. 15a to 15c, the same reference numerals have been assigned to components substantially identical to the electronic device (200) of FIG. 6a, and a detailed description thereof may be omitted.

[0146] Referring to FIGS. 15a through 15c, the electronic device (200) may include a first housing (210) having a first space (2101), a second housing (220) having a second space (2201), a motor (260) disposed in the first space (2101) and including a pinion gear (262), and a rack gear (263) disposed in the second space (2201) and geared with the pinion gear (262) (e.g., a connecting member). In one embodiment, the motor (260) may be fixed to the first housing (210) through a motor bracket (260a). In one embodiment, the rack gear (263) may have both ends fixed through a pair of fixing parts (2224, 2225) (e.g., a motor connecting part) provided on a second support plate (222). In one embodiment, the rack gear (263) may have both ends fixed to a pair of fixed parts (2224, 2225) respectively through a fastening member such as a screw or a tape member. In one embodiment, the rack gear (263) may have one end (2631) fixed to a first fixed part (2224) formed on a second support plate (222), and the other end (2632) fixed to a second fixed part (2225) formed on the second support plate (222). In one embodiment, the rack gear (263) may help reduce vibration by being spaced apart from the second support plate (222), except for the pair of fixed parts (2224, 2225).

[0147] According to various embodiments, the second housing (220) may include a vibration reduction structure positioned near a pair of fixed parts (2224, 2225). In one embodiment, the vibration reduction structure may include a first slit (2281) connected to a bulkhead (2226) positioned around at least a portion of the first fixed part (2224) and a high-rigidity structure, and a second slit (2282) connected to a sixth side wall (2213) and surrounding at least a portion of the second fixed part (2225). In one embodiment, vibration transmitted to the first fixed part (2224) according to the operation of the motor (260) may be transmitted to the bulkhead (2226), which is a high-rigidity structure, with the phenomenon of direct transmission to a surrounding weak-rigidity area through the first slit (2281) being blocked or reduced. In one embodiment, vibration transmitted to the second fixed part (2225) may be blocked or reduced from being directly transmitted to the surrounding weak-rigidity area through the second slit (2282) and may be transmitted to the sixth side wall (2213), which is a high-rigidity structure. Accordingly, vibration transmitted through the rack gear (263) may be reduced because the phenomenon of being directly transmitted to the weak-rigidity area through the first slit (2281) and / or the second slit (2282) is blocked or reduced, and is instead transmitted by bypass to the surrounding high-rigidity area (e.g., bulkhead (2226) and / or the sixth side (2213)) and then indirectly transmitted to the weak-rigidity area, and thus noise may also be reduced. In some embodiments, the first slit (2281) may be connected to the sixth side wall (2213), and the second slit (2282) may be configured to be connected to a bulkhead (not shown) placed around it. In some embodiments, the first slit (2281) and the second slit (2281) may both be configured to be connected to the surrounding sixth side wall (2213). In some embodiments, the first slit (2281) and the second slit (2281) may both be configured to be connected to the surrounding bulkhead (2226) (e.g., a rigid structure).
