Description

Electronic device including a guide structure of a driving structure

[0001] The various embodiments disclosed in this document relate to an electronic device including a guide structure of a driving 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 can have a deformable structure that allows for convenient portability and the use of large-screen displays. Electronic devices may include rollable electronic devices (e.g., sliderable electronic devices) capable of varying the display area of ​​a flexible display (e.g., rollable display) through the support of housings that operate in a sliding manner relative to each other. Rollable electronic devices may require an efficient arrangement structure of driving parts (e.g., driving modules) capable of sliding the remaining housings relative to one housing.

[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) in which the display area of ​​a flexible display (e.g., a rollable display, an expandable display, or a stretchable display) can be expanded and / or reduced depending on the operating state. The rollable electronic device may include a first housing and a second housing that are movably coupled to each other in a manner that is at least partially fitted together. For example, the first housing and the second housing operate to slide slidably to each other and support at least a portion of the flexible display, so that the flexible display is 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, as a driving unit (e.g., a driving module), a driving motor comprising a pinion gear that is disposed in one housing of the electronic device (e.g., a first housing or a second housing) and automatically moves the second housing to slide by a specified reciprocating distance relative to the first housing held by a user, and a rack gear disposed in the other housing (e.g., a second housing or a first housing) and geared with the pinion gear. For example, if the driving motor comprising the pinion gear is disposed in the first housing or the second housing, a rack gear having a length along the sliding direction and geared with the pinion gear may be disposed in the remaining housing.

[0006] A rollable electronic device may include a linear motion guide (LM guide) that guides the sliding of a first housing and a second housing, and a first rail structure that moves relative to the LM guide. The LM guide and the first rail structure may be placed on a counterpart. For example, if the LM guide is placed on the first housing or the second housing, the first rail structure may be placed on the remaining housing. The opposite structure may also be possible. The LM guide and the first rail structure may be placed on both sides of the electronic device to guide the sliding of the two housings.

[0007] Meanwhile, in the case of a rollable electronic device, in addition to the power required to drive electronic components, power may be required for a drive motor that drives the sliding motion of the electronic device. Therefore, the rate of battery power depletion of a rollable electronic device may be higher than that of other electronic devices (e.g., bar-type electronic devices). As described above, a rack gear, a drive motor, an LM guide, and a first rail structure may be arranged inside the rollable electronic device for sliding motion. Consequently, there is a limit to expanding the size of the battery because sufficient space for battery placement is not secured.

[0008] The problems to be solved in this disclosure are not limited to those mentioned above, and may be extended in various ways without departing from the spirit and scope of this disclosure.

[0009] According to one embodiment of the present disclosure, an electronic device may include a flexible display. The electronic device may include a first housing. The electronic device may include a second housing comprising a support plate, a first side and a second side extending on both sides of the support plate. The electronic device may include a first rail structure disposed on the first side of the second housing. The electronic device may include a sliding structure that is fixed to the first housing and coupled to the first rail structure, and at least a portion of which moves relative to the first rail structure in accordance with the movement of the first housing relative to the second housing. The electronic device may include a second rail structure disposed on the periphery of the second side on the support plate of the second housing and extending in the same direction as the direction of movement of the first housing relative to the second housing. The electronic device may include a drive unit comprising a drive motor and a first gear connected to the drive motor and rotated by the driving force of the drive motor. The electronic device may include a recess that accommodates the second rail structure and a second gear that directly meshes with the first gear to receive driving force through the first gear and moves linearly along the second rail structure to cause the first housing to move relative to the second housing. The electronic device may include a bearing member, at least a portion of which is disposed between the second rail structure and the recess of the second gear.

[0010] According to one embodiment of the present disclosure, an electronic device may include a flexible display. The electronic device may include a first housing. The electronic device may include a second housing comprising a support plate, a first side and a second side extending on both sides of the support plate. The electronic device may include a first rail structure disposed on the first side of the second housing. The electronic device may include a sliding structure that is fixed to the first housing and coupled to the first rail structure, and at least a portion of which moves relative to the first rail structure in accordance with the movement of the first housing relative to the second housing. The electronic device may include a second rail structure disposed on the periphery of the second side on the support plate of the second housing and extending in the same direction as the direction of movement of the first housing relative to the second housing. The electronic device may include a drive unit comprising a drive motor and a pinion gear connected to the drive motor and rotating by the driving force of the drive motor. The electronic device may include a recess in which the second rail structure is received, and may include a rack gear, one end of which is fixed to the first housing and engaged with the pinion gear to drive. The electronic device may include a bearing member, at least a portion of which is disposed between the second rail structure and the rack gear in the recess.

[0011] According to one embodiment of the present disclosure, an electronic device may include a flexible display. The electronic device may include a first housing. The electronic device may include a second housing comprising a support plate, a first side and a second side extending on both sides of the support plate. The electronic device may include a first rail structure disposed on the first side of the second housing. The electronic device may include a sliding structure that is fixed to the first housing and coupled to the first rail structure, and at least a portion of which moves relative to the first rail structure in accordance with the movement of the first housing relative to the second housing. The electronic device may include a second rail structure disposed on the periphery of the second side on the support plate of the second housing and extending in the same direction as the direction of movement of the first housing relative to the second housing. The electronic device may include a drive unit comprising a drive motor and a screw member connected to the drive motor and rotated by the driving force of the drive motor. The electronic device may include a recess in which the second rail structure is received and a fastening portion that is screw-coupled with the screw member, and may include a fastening structure that moves along the second rail structure based on the rotation of the screw member. The electronic device may include a bearing member, at least a portion of which is disposed between the second rail structure and the fastening structure in the recess.

[0012] According to various embodiments of the present disclosure, either of the first rail structures disposed on both sides of the electronic device may be omitted. For example, the first rail structure disposed adjacent to the rack gear among the first rail structures may be omitted. A second rail structure may be disposed in either the first housing or the second housing to replace the omitted first rail structure. The rack gear may include a recess that accommodates the second rail structure. The rack gear may be engaged with the pinion gear of a drive motor so that movement may be guided through the second rail structure during operation. In an embodiment where the first rail structure disposed adjacent to the rack gear is omitted, compared to the case where the first rail structure adjacent to the rack gear is disposed on the side of the electronic device, additional space may be secured on the left and right sides of the rack gear. Accordingly, the size of the battery may be expanded by the amount of space created by the omission of the first rail structure adjacent to the rack gear. Consequently, the battery size may be increased, thereby increasing the battery capacity.

The communication module (190) may include one or more communication processors that operate independently of the processor (120) (e.g., application processor) and support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., cellular communication module, short-range wireless communication module, or GNSS (global navigation satellite system) communication module) or a wired communication module (194) (e.g., LAN (local area network) communication module, or power line communication module). The corresponding communication module among these communication modules can communicate with an external electronic device (104) through a first network (198) (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network (199) (e.g., a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can identify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) using subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)) stored in the subscriber identification module (196).

[0055] The wireless communication module (192) can support 5G networks and next-generation communication technologies following 4G networks, for example, new radio access technology. NR access technology can support high-speed transmission of high-capacity data (enhanced mobile broadband (eMBB)), minimization of terminal power and connection of multiple terminals (massive machine type communications (mMTC)), or high reliability and low latency (ultra-reliable and low-latency communications (URLLC)). The wireless communication module (192) can support a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate, for example.

[0058] At least some of the above components can be connected to each other via a communication method between peripheral devices (e.g., bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)) and exchange signals (e.g., commands or data) with each other.

[0059] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) through a server (108) connected to a second network (199). Each of the external electronic devices (102, or 104) may be the same or different type of device as the electronic device (101). According to one embodiment, all or part of the operations performed on the electronic device (101) may be performed on one or more of the external electronic devices (102, 104, or 108). For example, if the electronic device (101) needs to perform a function or service automatically or in response to a request from a user or another device, the electronic device (101) may request one or more external electronic devices to perform at least part of the function or service instead of performing the function or service itself or additionally.

The electronic device (101) may provide the result as is or additionally processed as at least part of the response to the request. For this purpose, for example, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used. The electronic device (101) may provide ultra-low latency services using, for example, distributed computing or mobile edge computing. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device.

In one embodiment, the sensor module (176) may detect a first state, an inward state, in which the second housing (220) is fully drawn in from the first housing (210), or a second state, an outward state, in which the second housing is fully drawn out from the first housing (210), or an intermediate state between the inward state and the outward state. In some embodiments, the processor (120) detects the distance traveled in real time while the second housing (220) is moving from the first housing (210) through the sensor module (176), and a flexible display (e.g., the flexible display (230) of FIG. 4a) Through this, the display module (160) may be controlled to display an object corresponding to the variable display area. In one embodiment, the electronic device (101) may include a drive motor control module (181) for controlling the operation of a drive motor (e.g., a DC motor or a stepping motor) (e.g., the drive motor (260) of FIG. 4a) placed inside the electronic device.

In one embodiment, the drive 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 (261) and the rack gear (262). 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 drive motor (260) and the rack gear (262). In one embodiment, the first housing (210) may include a first side member (211), a first extension member (212) extending from the first side member (211), and a first rear cover (213) coupled to the first extension member (212). In one embodiment, the second housing (220) may include a second rear cover (223) coupled with a second side member (221) and a support plate (222) extending from the second side member (221).

[0092] 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) exposed to the outside.

[0093] 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 drive motor (260).

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 (262) may be placed in the second housing (220), and the drive motor (260) including the pinion gear (261) may be placed in the first housing (210).

[0094] FIG. 6a is a drawing showing the back of an electronic device in an inserted state according to various embodiments of the present disclosure. FIG. 6b is a drawing showing the back of an electronic device in an withdrawn state according to various embodiments of the present disclosure.

[0095] Referring to FIGS. 6a and 6b, an electronic device (200) (e.g., the electronic device (200) of FIG. 4a) may include a drive motor (260) comprising a second gear (e.g., a rack gear (262)) that is fixed to at least a part (e.g., the support bracket (225) of FIG. 4a) of a first housing (e.g., the first housing (210) of FIG. 4a) and extends into a second housing (e.g., the second housing (220) of FIG. 4a), and a first gear (e.g., the pinion gear (261) of FIG. 5a), a rotating member) that is disposed in the second housing (220) and geared with the second gear (e.g., the rack gear (262)). In one embodiment, the drive motor (260) may be disposed in a second space (2201) of the second housing (220).

[0096] Referring to FIGS. 6a through 9 below, the first gear (e.g., pinion gear (261)) may be a pinion gear (261) that is gear-coupled (e.g., connected, or fastened) with the second gear (e.g., rack gear (262)) and connected to the drive motor (260) to receive driving force from the drive motor (260) and rotate. Referring to FIGS. 6a through 9 below, the second gear (e.g., rack gear (262)) may represent a structure that receives driving force from the drive motor (260) and moves in a sliding direction (e.g., ±y axis direction). For example, the second gear (e.g., rack gear (262)) may be a rack gear (262) that is gear-coupled with the pinion gear (261) of the drive motor (260) and moves in a sliding direction (e.g., ±y axis direction) (e.g., rack gear (262) of FIGS. 6a through 9). The second gear described in FIGS. 6a to 9 below is described on the premise that it is a rack gear (262). Also, the first gear described in FIGS. 6a to 9 is described on the premise that it is a pinion gear (261).

[0097] In one embodiment, referring to FIGS. 10a through 12 to be described below, a second gear (e.g., a fastening structure (e.g., the fastening structure (412) of FIG. 11a)) may be connected (e.g., fastened) to a first gear (e.g., a screw member (411)). The first gear (e.g., a screw member (411)) may be a screw member (411) (e.g., a lead screw and / or an auger) that receives driving force from a drive motor (260) and rotates about the axis of the drive motor (260). The second gear (e.g., the fastening structure (412)) may be screw-coupled to a screw member (411) (e.g., a lead screw and / or an auger) that receives driving force from the drive motor (260) and rotates about the axis of the drive motor (260), and may move in a sliding direction (e.g., ±y axis direction). The second gear described in FIGS. 10a through 12 below The explanation is based on the premise that the gear is a fastening structure (412) and the first gear is a screw member (411).

[0098] Additionally, in the embodiments of FIGS. 6a to 15 below, the first rail structure (227) fixed to the second housing (220) may be disposed only on one side of the second housing (220). For example, the first rail structure (227) disposed adjacent to the second gear (e.g., rack gear (262), fastening structure (412), guide member) among the first rail structures (227) may be omitted. In summary, the first rail structure (227) may be coupled to the fifth side (2212) of the second housing (220) and may not be coupled to the sixth side (2213). A second rail structure (e.g., rail, guide block, second rail structure (300) of FIG. 7a, and / or second rail structure (400) of FIG. 11a) may be disposed on the support plate (222) of the second housing (220). The second rail structure (300) may be formed integrally with the support plate (222) of the second side member (221) or formed separately and disposed on the support plate (222). In one embodiment, the second rail structure (300, 400) may be disposed around the sixth side (2213) on the support plate (222) and may extend in the same direction as the extension direction of the first housing (210) relative to the second housing (220). The second rail structure (300) may be formed to extend in the sliding direction of the electronic device (200) (e.g., the direction of movement of the second housing (220) relative to the first housing (210) or the direction of movement of the first housing (210) relative to the second housing (220). In one embodiment, at least a portion of the second gear (262, 412) may be coupled to the first housing (210).The second gear (262, 412) is directly engaged with the first gear (261, 411) to receive driving force through the first gear (262, 412) and can move linearly (e.g., in the Y-axis direction of FIG. 6a) along the second rail structure (300, 400) (e.g., the second rail structure (300) of FIG. 8a, the second rail structure (400) of FIG. 11a) to guide the first housing (210) to move relative to the second housing (220). Thus, the first housing (210) can move linearly relative to the second housing (220) based on the linear movement of the sliding structure (226) relative to the first rail structure (227) (e.g., in the Y-axis direction of FIG. 6a) and the linear movement of the second gear (262) relative to the second rail structure (300).

[0099] In one embodiment, referring to FIGS. 8a through 8c to be described later, the rack gear (262) may include a recess (263) that accommodates the second rail structure (300). The rack gear (262) may be guided to move in a sliding direction (e.g., ±y axis direction) through the second rail structure (300). Accordingly, the rack gear (262) may move the first housing (210) in an inward direction (e.g., +y axis direction) or an outward direction (e.g., -y axis direction) relative to the second housing (220) by receiving the driving force of the drive motor (260) from the pinion gear (261) while in a gear-coupled state with the pinion gear (261).

[0100] FIG. 7a is a drawing in which a bearing fixing member is disposed on a first rail structure formed in a second housing according to various embodiments of the present disclosure. FIG. 7b is a cross-sectional view taken along the line 7b-7b of FIG. 7a.

[0101] According to various embodiments, as illustrated in FIGS. 7a and 7b, the electronic device (200) may include a second rail structure (300) (e.g., a rail, a guide block). In one embodiment, at least a portion of the second rail structure (300) may be disposed in a second space (2201) of the second housing (220). The second rail structure (300) may be disposed on a support plate (222) of a second side member (221) of the second housing (220). In one embodiment, the second rail structure (300) may be disposed adjacent to a side of the second housing (220). For example, the second rail structure (300) may be disposed adjacent to a sixth side (2213) of a second side member (221) of the second housing (220). In some embodiments, the second rail structure (300) may be positioned adjacent to the fifth side (2212) of the second side member (221).

[0102] In one embodiment, referring to FIGS. 7a and 7b, the second rail structure (300) may be formed integrally with the support plate (222). In one embodiment, the second rail structure (300) may be formed separately from the support plate (222) and at least a portion thereof may be disposed on the support plate (222). For example, the second rail structure (300) may be formed on a separate bracket disposed on the support plate (222).

[0103] According to various embodiments, as illustrated in FIG. 7b, the second rail structure (300) may include a first guide groove (301) (e.g., the first guide groove (301) of FIG. 8a) formed along the sliding direction (e.g., ±y axis direction) or movement direction of the rack gear (262) (e.g., the second gear). In one embodiment, the first guide groove (301) may be formed on a surface facing the first side (262b) and the second side (262c) of the rack gear (262) to be described later. In one embodiment, a bearing member (b) (e.g., a bearing ball) that guides the sliding (e.g., movement) of the rack gear (262) relative to the second rail structure (300) may be disposed in the first guide groove (301) of the second rail structure (300). In one embodiment, the first guide groove (301) may be formed in a shape that corresponds to at least a portion of the bearing member (b). A bearing member (b) is positioned between the rack gear (262) and the second rail structure (300) in the recess (263) of the rack gear (262) to guide the sliding of the rack gear (262) relative to the second rail structure (300).

[0104] According to various embodiments, as illustrated in FIGS. 7a and 7b, the bearing member (b) may be positioned at a designated location (e.g., a first guide groove (301)) of the second rail structure (300) through a bearing fixing member (270) (e.g., a moving member, a sliding member). The bearing fixing member (270) may prevent the bearing member (b) from disengaging from the first guide groove (301) of the second rail structure (300). In one embodiment, the bearing fixing member (270) may include a hole (271) for receiving the bearing member (b). In one embodiment, the bearing fixing member (270) may guide sliding of the bearing member (b) along the second rail structure (300). In one embodiment, as described below, at least a portion of the bearing fixing member (270) may be received in a recess (263) of the rack gear (262). A second guide groove (264) corresponding to the first guide groove (301) (e.g., the second guide groove (264) of FIG. 8a) may be formed inside the recess (263) of the rack gear (262). In one embodiment, the second guide groove (264) may be formed in a shape that corresponds to at least a portion of the bearing member (b). A portion of the bearing member (b) may be placed in the second guide groove (264) while being positioned so as not to be dislodged from the first guide groove (301) through the bearing fixing member (270). Thus, the rack gear (262) can move in a sliding direction relative to the second rail structure (300) through the bearing member (b).

[0105] FIGS. 8A and 8B are drawings illustrating the assembly relationship of a drive motor, a pinion gear, a rack gear, a bearing fixing member, and a first rail structure according to various embodiments of the present disclosure. FIG. 8C is a cross-sectional view taken along the line 8c-8c of FIG. 8B.

[0106] According to various embodiments, as illustrated in FIGS. 8a, 8b, and 8c, the rack gear (262) may include a recess (263) that accommodates the second rail structure (300). In one embodiment, the second rail structure (300) may be accommodated in the recess (263) of the rack gear (262) and wrapped around the rack gear (262). In one embodiment, a lubricant such as grease may be applied to the recess (263) of the rack gear (262). Thus, friction caused by contact between the second rail structure (300) and the rack gear (262) can be reduced during the movement of the rack gear (262) relative to the second rail structure (300).

[0107] In one embodiment, the rack gear (262) may include a gear surface (262a) having teeth formed thereon that engage directly with the pinion gear (261) (e.g., the first gear), and a first side (262b) and a second side (262c) that extend from the gear surface (262a) in directions opposite to each other. The rack gear (262) may engage directly with the pinion gear (261) to receive driving force through the pinion gear (261) and move linearly (e.g., in the Y-axis direction of FIG. 8a) along the second rail structure (300) to allow the first housing (210) to move relative to the second housing (220).

[0108] According to one embodiment, as shown in FIG. 8b, the rack gear (262) may be positioned such that at least a portion is received in the motor bracket (260a) and is placed between the pinion gear (261) and the second rail structure (300). In one embodiment, the rack gear (262) may be positioned such that the gear face (262a) is engaged with the pinion gear (261) and the back face (262d) of the gear face (262a) (e.g., the back face (262d) of FIG. 9) faces the second rail structure (300).

[0109] According to one embodiment, as illustrated in FIGS. 8a, 8b, and 8c, the bearing member (b) may be positioned between the first side (262b) of the rack gear (262) and the second rail structure (300) and / or between the second side (262c) of the rack gear (262) and the second rail structure (300). In one embodiment, the rack gear (262) may include a second guide groove (264) corresponding to the first guide groove (301) of the second rail structure (300). In one embodiment, the second guide groove (264) may be located within the recess (263) of the rack gear (262). In one embodiment, the second guide groove (264) may be formed to face the first guide groove (301) on the first side (262b) and / or the second side (262c) of the rack gear (262). The bearing member (b) is positioned between the first guide groove (301) and the second guide groove (264) to guide the movement of the rack gear (262) relative to the second rail structure (300).

[0110] According to various embodiments, the drive motor (260) may be supported through a motor bracket (260a) that is fixed to the second housing (220). In one embodiment, the rack gear (262) may be slidably coupled to the motor bracket (260a) and may be geared with a pinion gear (e.g., the pinion gear (261) of FIG. 5a). For example, the rack gear (262) may be fixed with one end coupled to the support bracket (225) of the first housing (210), receive driving force from the drive motor (260) through the pinion gear (261), be supported through the motor bracket (260a), and move relative to the drive motor (260).

[0111] According to various embodiments, as illustrated in FIGS. 8a through 8c, the bearing fixing member (270) may be slidably disposed in the second rail structure (300) via the bearing member (b). In one embodiment, at least a portion of the bearing fixing member (270) may be disposed inside the recess (263) of the rack gear (262). In some embodiments, depending on the position in which the rack gear (262) is moved, a portion of the bearing fixing member (270) may be exposed outside the rack gear (262). In one embodiment, the bearing fixing member (270) may move along the second rail structure (300) when the rack gear (262) moves in a sliding direction (e.g., ±y axis direction) through the driving force of the drive motor (260), and may guide the movement of the rack gear (262) relative to the second rail structure (300).

[0112] In a comparative embodiment, first rail structures (227) (e.g., the first rail structures (227) of FIG. 4a) may be disposed on the sides of the second housing (220) (e.g., the fifth side (2212), the sixth side (2213)). According to one embodiment of the present disclosure, the first rail structure (227) disposed adjacent to the rack gear (262) among the first rail structures (227) may be omitted. For example, the first rail structure (227) may not be coupled to the sixth side (2213) of the second housing (220). In place of the omitted first rail structure (227), a second rail structure (300) may be disposed on the support plate (222) of the second housing (220). In one embodiment, referring to FIG. 8a through 8c, the second rail structure (300) is placed on the lower part of the rack gear (262) (e.g., It is located in the +Z direction of FIG. 8a) and can be accommodated in the recess (263) of the rack gear (262). In this case, compared to the case where the first rail structure (227) adjacent to the rack gear (262) is placed on the side of the second housing (220), the embodiments of FIG. 6a through 8c allow for additional space to be secured on the left and right sides of the rack gear (262) by the amount of space occupied by the first rail structure (227) as the first rail structure (227) adjacent to the rack gear (262) is omitted. Therefore, the size of the battery (B) can be expanded by the amount of space created by the omission of the first rail structure (227) adjacent to the rack gear (262). As additional space is secured for the battery (B) to be placed, the size of the battery is increased, and the capacity of the battery (B) can be increased.

[0113] Meanwhile, the electronic device (200) may include a pair of sliding structures (226). In one embodiment, the pair of sliding structures (226) are positioned on the left and right sides of the electronic device (200) and can guide both ends of a support member (240) that supports a flexible display (230) in a sliding direction. For example, the sliding structures (226) may be fixed to both sides of a support bracket (225) and positioned adjacent to the second side (2112) and the third side (2113) of the first side member (211) of the first housing (210), respectively. In one embodiment, the sliding structure (226) positioned adjacent to the rack gear (262) (e.g., the sliding structure (226) adjacent to the third side (2113) of FIG. 6a) can be formed with a thinner thickness compared to the sliding structure (226) into which the first rail structure (227) is inserted (e.g., the sliding structure (226) adjacent to the second side (2112) of FIG. 6a) since the first rail structure (227) adjacent to the rack gear (262) is omitted. Accordingly, the size of the battery (B) can be expanded by the amount of space created by omitting the first rail structure (227) adjacent to the rack gear (262). As additional space is secured for the battery (B) to be placed, the size of the battery (B) can be increased, thereby increasing the capacity of the battery (B). In the following description, the sliding structure (226) located adjacent to the third side (2113) of the first housing (210) is described on the premise that it is omitted. For example, the sliding structure (226) may be coupled to the portion facing the second side (2112) of the first housing (210) from the support bracket (225). The sliding structure (226) may not be coupled to the portion adjacent to the third side (2113) of the first housing (210) from the support bracket (225).

[0114] FIG. 9 is a diagram showing the arrangement relationship of a pinion gear, a rack gear, a bearing fixing member, and a second rail structure according to various embodiments of the present disclosure.

[0115] According to various embodiments, as illustrated in FIG. 9, the arrangement structure of the pinion gear (261) (e.g., first gear), rack gear (262) (e.g., second gear), bearing fixing member (270), and second rail structure (300) can be varied. In one embodiment, FIG. 9(a) is a diagram of the stacking relationship of pinion gear (261) - rack gear (262) - bearing fixing member (270) - second rail structure (300), as described in FIG. 8a to 8c. In one embodiment, referring to FIG. 9(b) and (c), the rack gear (262) is placed on the bearing fixing member (270) such that its back surface (262d) faces the side of the second rail structure (300) in which the first guide groove (301) is formed, and the gear portion (262a) can be gear-coupled with the pinion gear (261). In one embodiment, the rack gear (262) can be guided to move along the second rail structure (300) through the bearing fixing member (270) as the back surface (262d) is fixed to the bearing fixing member (270).

[0116] According to various embodiments, as illustrated in FIG. 9 (d) and (e), the bearing fixing member (270) may accommodate a pinion gear (261), a rack gear (262), and a second rail structure (300). In one embodiment, referring to FIG. 9 (d), the arrangement may be arranged in the order of rack gear (262) - pinion gear (261) - second rail structure (300). In one embodiment, a portion of the bearing fixing member (270) may be placed on the back surface (262d) of the rack gear (262) to accommodate the rack gear (262) - pinion gear (261) - second rail structure (300). In one embodiment, referring to FIG. 9 (e), the arrangement may be arranged in the order of pinion gear (261) - rack gear (262) - second rail structure (300). In one embodiment, the bearing fixing member (270) may be positioned to accommodate the pinion gear (261) - rack gear (262) - second rail structure (300).

[0117] In addition, the positions of the pinion gear (261), rack gear (262), and second rail structure (300) can be varied.

[0118] In the above description, the driving motor (260) is positioned in the second housing (220), the rack gear (262) is coupled to the support bracket (225) and positioned in at least a part of the second housing (220) in the retracted or withdrawn state of the electronic device (200), and the second rail structure (300) is positioned on the support plate (222) of the second housing (220), although the description is based on this premise, but is not limited thereto. In one embodiment, the positioning of the driving motor (260), the rack gear (262), and / or the second rail structure (300) may be varied in many ways. In one embodiment, the driving motor (260), the pinion gear (261), and the motor bracket (260a) may be positioned in the first space (2101) of the first housing (210). For example, a drive motor (260), a pinion gear (261), and a motor bracket (260a) may be fixed to a first extension member (212) of a first housing (210). In this case, the rack gear (262) may be coupled with a second housing (220) so that at least a portion of the first housing (210), which is the counterpart to the second housing (220), may be positioned in the retracted or withdrawn state of the electronic device (200). In one embodiment, a second rail structure (300) may be positioned on the first extension member (212) of the first housing (210). For example, the second rail structure (300) may be positioned on the first extension member (212) and adjacent to a second side (2112) or a third side (2113) of a first side member (211).

[0119] However, for the convenience of explanation, the following description is to be explained on the premise that the drive motor (260), pinion gear (261), and motor bracket (260a) are placed in the second housing (220), the second gear (e.g., rack gear (262), the fastening structure (412) of FIG. 11a) is coupled with the support bracket (225) of the first housing (210), and the second rail structure (300) is placed on the support plate (222) of the second housing (220).

[0120] FIG. 10a is a drawing showing the back of an electronic device in an inserted state according to various embodiments of the present disclosure. FIG. 10b is a drawing showing the back of an electronic device in an withdrawn state according to various embodiments of the present disclosure.

[0121] According to various embodiments, as illustrated in FIG. 10a and FIG. 10b, an electronic device (e.g., electronic device (200) of FIG. 4a and 10a) may include a second gear (e.g., fastening structure (e.g., nut structure, moving structure)) (412) which is fixed to at least a part of a first housing (e.g., first housing (210) of FIG. 4a and 10a) (e.g., support bracket (225) of FIG. 4a and 10a) and extends to a second housing (e.g., second housing (220) of FIG. 4a and 10a), a first gear (e.g., screw member, lead screw and / or auger) (411) which is placed at least a part of the second housing (220) and screw-coupled with the fastening structure (412), and a driving motor (260) which provides driving force to the first gear (411) to rotate the first gear (411). In one embodiment, the drive motor (260) and the motor bracket (260a) may be placed in the second space (2201) of the second housing (220).

[0122] In the following description, the first gear (411) is described as a screw member (411), and the second gear (412) is described as a fastening structure (412). The fastening structure (412) may be screw-coupled with the screw member (411). The fastening structure (412) may include a fastening portion (4121) (e.g., a nut structure, a nut member, and / or a nut) that is screw-coupled with the screw member (411). As the screw member (411) rotates via the motor (260), the fastening structure (412) may not rotate together with the screw member (411) but may move linearly in the sliding direction (e.g., ±y-axis direction) of the electronic device (200) relative to the screw member (411). For example, the fastening structure (412) may be directly engaged with the screw member (411) while partially coupled to the first housing (210) to receive driving force through the screw member (411) and move linearly along the second rail structure (300) (e.g., in the Y-axis direction of FIG. 10a) so that the first housing (210) can move relative to the second housing (220).

[0123] In a comparative embodiment, first rail structures (227) (e.g., the first rail structures (227) of FIG. 4a) may be disposed on the sides of the second housing (220) (e.g., the fifth side (2212), the sixth side (2213)). According to one embodiment of the present disclosure, the first rail structure (227) disposed adjacent to the fastening structure (412) among the first rail structures (227) may be omitted. For example, the first rail structure (227) may not be coupled to the sixth side (2213) of the second housing (220). In place of the omitted first rail structure (227), a second rail structure (400) may be disposed on the support plate (222) of the second housing (220). The second rail structure (400) may extend in the sliding direction (e.g., ±y axis direction) of the electronic device (200). Fastening The structure (412) may include a recess (413) (e.g., the recess (413) of FIG. 11a) that accommodates the second rail structure (400). The fastening structure (412) may be guided to move in the sliding direction of the electronic device (200) through the second rail structure (400). Meanwhile, a sliding structure (226) may be disposed on the second side (2112) of the first housing (210), and a first rail structure (227) may be disposed on the fifth side (2212) of the second housing (220) so as to be linearly movable with respect to the sliding structure (226). Accordingly, the first housing (210) may have a second rail structure (227) based on the linear movement of the sliding structure (226) relative to the first rail structure (227) (e.g., movement in the Y-axis direction of FIG. 10a) and the linear movement of the fastening structure (412) relative to the second rail structure (400). It can move linearly with respect to the housing (220).

[0124] According to various embodiments, as illustrated in FIG. 10a and FIG. 10b, the electronic device (200) may include a second rail structure (400) (e.g., a rail, a guide block, and / or the second rail structure (300) of FIG. 7a). In one embodiment, at least a portion of the second rail structure (400) may be disposed in the second space (2201) of the second housing (220). The second rail structure (400) may be disposed on the support plate (222) of the second side member (221) of the second housing (220). In one embodiment, the second rail structure (300) may be disposed adjacent to the side of the second housing (220). For example, the second rail structure (300) may be disposed adjacent to the sixth side (2213) of the second side member (221) of the second housing (220). In some embodiments, the second rail structure (300) may be positioned adjacent to the fifth side (2212) of the second side member (221).

[0125] According to various embodiments, as illustrated in FIG. 10a and FIG. 10b, the second rail structure (400) may be formed separately from the support plate (222) and at least a portion thereof may be disposed on the support plate (222). For example, referring to FIG. 11a, the second rail structure (400) may be formed on a bracket (420) that supports a screw member (411). In one embodiment, the bracket (420) may be disposed on the support plate (222) of the second side member (221). In this case, the second rail structure (400) may be disposed on the support plate (222) together with the bracket (420). In one embodiment, the second rail structure (400) may be formed integrally on the support plate (222) as a separate configuration from the bracket (420). For example, the bracket (420) and the second rail structure (400) can be positioned adjacently on the support plate (222).

[0126] According to various embodiments, as illustrated in FIG. 10a and FIG. 10b, the fastening structure (412) may be secured by being coupled to at least a portion of the support bracket (225) of the first housing (210). For example, the coupling portion (4122) of the fastening structure (412) may be coupled to the side of the support bracket (225) (e.g., the side facing the -X direction in FIG. 10a). Based on the fastening structure (412) moving along the screw member (411) in the sliding direction (e.g., ±y axis direction) of the electronic device (200), the first housing (210) may be moved in the inward direction (e.g., +y axis direction) or the outward direction (e.g., -y axis direction) relative to the second housing (220).

[0127] FIGS. 11a, 11b, and 11c are drawings of the arrangement relationships of a drive motor, a screw member, and a fastening structure according to various embodiments of the present disclosure. FIG. 12 is a drawing of the arrangement relationships of a screw member, a fastening structure, a bearing member, and a first rail structure according to various embodiments of the present disclosure.

[0128] According to various embodiments, as illustrated in FIG. 10a, FIG. 10b and FIG. 11b above, a fastening structure (412) (e.g., a second gear) may include a main body (4120) having a recess (413), a fastening part (4121) into which a screw member (411) (e.g., a first gear) is inserted, a coupling part (4122) coupled with a support bracket (225), and a side part (e.g., a main body part, a body) (4123) having a rail (415) into which one end of a support member (240) is inserted. Each component of the fastening structure (412) may not be physically separated and may be conceptually separated for convenience of explanation.

[0129] According to various embodiments, as illustrated in FIG. 11a and FIG. 11b, the screw member (411) may have a thread (e.g., a male thread) formed thereon. The fastening portion (4121) of the fastening structure (412) may have a thread (e.g., a female thread) formed thereon that engages with the thread of the screw member (411). In one embodiment, the screw member (411) may rotate relative to the fastening portion (4121) of the fastening structure (412) by engaging with the fastening portion (4121) as it is rotated by a drive motor (260). The fastening structure (412) may move along the screw member (411) in the sliding direction (e.g., ±y axis direction) of the electronic device (200) without rotating together with the screw member (411) based on the rotation of the screw member (411). For example, the fastening structure (412) can move in a sliding direction (e.g., ±y axis direction) relative to the screw member (411) by an amount corresponding to the pitch of the threads formed on the screw member (411) for every rotation of the screw member (411).

[0130] According to various embodiments, as illustrated in FIG. 11b and FIG. 11c, one end of the screw member (411) may be physically connected to a drive motor (260). With one end of the screw member (411) connected to the drive motor (260), it may sequentially pass through a motor bracket (260a) and a fastening portion (4121) of a fastening structure (412). The bracket (420) may include a fixing portion (421) that supports the end of the screw member (411). In one embodiment, the fixing portion (421) may include a hole into which the end of the screw member (411) is inserted. The fixing portion (421) may not have a force acting to move the screw member (411) in a sliding direction (e.g., ±y axis direction) as the end of the screw member (411) idles within the hole of the fixing portion (421).

[0131] According to various embodiments, as illustrated in FIG. 11c, the second rail structure (400) may include a first guide groove (401) formed along the sliding direction (e.g., ±y axis direction) or movement direction of the fastening structure (412). In one embodiment, the fastening structure (412) may include a second guide groove (414) facing the first guide groove (401) and corresponding to the first guide groove (401). In one embodiment, the second guide groove (414) may be located inside the recess (413) and formed on a surface facing the surface of the second rail structure (400) where the first guide groove (301) is formed. In one embodiment, a bearing member (b) (e.g., a bearing ball) that guides the sliding (e.g., movement) of the fastening structure (412) relative to the second rail structure (400) may be disposed between the first guide groove (401) of the second rail structure (400) and the second guide groove (414) of the fastening structure (412). In one embodiment, the first guide groove (401) and the second guide groove (414) may be formed with a shape in which at least a portion corresponds to the bearing member (b). The bearing member (b) may be disposed between the fastening structure (412) and the second rail structure (400) in the recess (413) of the fastening structure (412) to guide the sliding of the fastening structure (412) relative to the second rail structure (400).

[0132] According to various embodiments, as illustrated in FIGS. 11a and 11c, the bearing member (b) may be positioned at a designated location (e.g., a first guide groove (401)) of the second rail structure (400) through a bearing fixing member (270) (e.g., a moving member, a sliding member). The bearing fixing member (270) may prevent the bearing member (b) from disengaging from the first guide groove (401) of the second rail structure (400). In one embodiment, the bearing fixing member (270) may include a hole (271) (e.g., the hole (271) in FIG. 7b) for receiving the bearing member (b). In one embodiment, the bearing fixing member (270) may guide sliding of the bearing member (b) through the second rail structure (400). In one embodiment, at least a portion of the bearing fixing member (270) may be received in a recess (413) of the fastening structure (412). A portion of the bearing member (b) may be placed in the second guide groove (414) while being positioned so as not to be dislodged from the first guide groove (401) through the bearing fixing member (270). Accordingly, the fastening structure (412) can move in a sliding direction relative to the second rail structure (400) through the bearing member (b).

[0133] According to various embodiments, the bearing fixing member (270) may be slidably disposed on the second rail structure (400) via the bearing member (b). In one embodiment, at least a portion of the bearing fixing member (270) may be disposed inside the recess (413) of the fastening structure (412). In some embodiments, depending on the position in which the fastening structure (412) is moved, a portion of the bearing fixing member (270) may be exposed outside the fastening structure (412). In one embodiment, the bearing fixing member (270) may move along the second rail structure (400) when the fastening structure (412) moves in a sliding direction (e.g., ±y-axis direction) relative to the second rail structure (400) via the screw member (411), and may guide the movement of the fastening structure (412) relative to the second rail structure (400).

[0134] In one embodiment, the second rail structure (400) may be received in the recess (413) of the fastening structure (412) and wrapped through the fastening structure (412). In one embodiment, referring to FIG. 12 (a), (b), (c), and (d), the fastening structure (412) may receive the second rail structure (400) in various ways. In one embodiment, referring to FIG. 12 (a), (c), and (d), the fastening structure (412) may receive the second rail structure (400) with one side open. In one embodiment, referring to FIG. 12 (b), the fastening structure (412) may be formed in a shape that wraps around the second rail structure (400). In one embodiment, a lubricant such as grease may be applied to the recess (413) of the fastening structure (412). Therefore, when the fastening structure (412) moves toward the second rail structure (400), friction caused by contact between the fastening structure (412) and the second rail structure (400) can be reduced.

[0135] According to various embodiments, as illustrated in FIG. 11a and FIG. 11c, a rail (415) may be formed in the side portion (4123) of the fastening structure (412) into which one end of a support member (240) supporting a flexible display (230) is inserted. Referring to FIG. 10a and FIG. 10b mentioned above, the sliding structure (226) may be fixed to one side of the support bracket (225) (e.g., the side facing the + X direction in FIG. 10a) and positioned adjacent to the second side (2112) of the first side member (211) of the first housing (210). In one embodiment, the fastening structure (412) may be fixed to the other side of the support bracket (225) (e.g., the side facing the - X direction in FIG. 10a) and positioned adjacent to the third side (2113) of the first side member (211) of the first housing (210). In one embodiment, the support member (240) may be guided at one end in a sliding direction (e.g., ± y-axis direction) through a sliding structure (226), and at the other end in a sliding direction (e.g., ± y-axis direction) through a rail (415) formed in a fastening structure (412). In some embodiments, the fastening structure (412) may not have a rail (415) formed to support the support member (240). In this case, the sliding structure (226) may be fixed to both sides of the support bracket (225) and positioned adjacent to the second side (2112) of the first side member (211) of the first housing (210). Accordingly, the support member (240) supporting the flexible display (230) can move based on the sliding motion of the electronic device (200) as one end is inserted into the rail (not shown) of the sliding structure (226) and the other end is inserted into the rail (415) of the fastening structure (412).

[0136] In the above description, the driving motor (260) is positioned in the second housing (220), the fastening structure (412) is coupled to the support bracket (225) and positioned in at least a part of the second housing (220) in the retracted or withdrawn state of the electronic device (200), and the second rail structure (400) is positioned on the support plate (222) of the second housing (220), although the description is based on this premise, it may not be limited thereto. In one embodiment, the positioning of the driving motor (260), the rack gear (262), and / or the second rail structure (400) may be varied in many ways. In one embodiment, the driving motor (260) and the motor bracket (260a) may be positioned in the first space (210) of the first housing (210). For example, the drive motor (260) and the motor bracket (260a) may be fixed to the first extension member (212) of the first housing (210). In this case, the fastening structure (412) may be coupled with the second housing (220) so that at least a portion of it may be disposed on the first housing (210), which is the counterpart to the second housing (220), in the inlet or outlet state of the electronic device (200). In one embodiment, the second rail structure (400) may be disposed on the first extension member (212) of the first housing (210). For example, the second rail structure (400) may be disposed on the first extension member (212) and adjacent to the third side (2113) of the first side member (211).

[0137] FIG. 13 is a drawing showing the back of an electronic device in an extended state according to various embodiments of the present disclosure. FIG. 14 is a drawing showing the coupling relationship of a chain member coupled to a pinion gear of a drive motor, a chain guide member guiding the chain member, and a sliding structure movably coupled to the chain guide member according to various embodiments of the present disclosure. FIG. 15 is a cross-sectional view taken along line 15-15 of FIG. 13.

[0138] According to various embodiments, as illustrated in FIGS. 13, 14 and 15, an electronic device (e.g., the electronic device (200) of FIGS. 4a and 10a) may include a chain member (520) that is fixed to at least a portion of a first housing (e.g., the first housing (210) of FIGS. 4a and 10a) (e.g., the support bracket (225) of FIGS. 4a and 10a) and extends into a second housing (e.g., the second housing (220) of FIGS. 4a and 10a) and engages with a pinion gear (261) of a drive motor (260) disposed in a second space (2201) of the second housing (220). In one embodiment, the chain member (520) may be engaged with the pinion gear (261) and moved in the sliding direction of the electronic device (e.g., ±y axis direction). In one embodiment, a chain fixing part (521) located at the end of the chain member (520) can be coupled to and fixed to a support bracket (225). Accordingly, the support bracket (225) can move in a direction of retraction (e.g., +Y direction in FIG. 13) or withdrawal (e.g., -Y direction in FIG. 13) relative to the second housing (220) based on the sliding of the chain member (520).

[0139] According to one embodiment, as shown in FIGS. 14 and 15, the chain member (520) is positioned on a rail (511) formed by extending in a sliding direction from the chain guide member (510) so that movement through the pinion gear (261) can be guided. In one embodiment, the chain guide member (510) may be positioned extending from the first housing (210) to the second housing (220).

[0140] In a comparative embodiment, first rail structures (227) (e.g., the first rail structures (227) of FIG. 4a) may be disposed on the sides of the second housing (220) (e.g., the fifth side (2212), the sixth side (2213)). According to one embodiment of the present disclosure, as shown in FIG. 13, the first rail structure (227) disposed adjacent to the rack gear (262) among the first rail structures (227) may be omitted. For example, the first rail structure (227) disposed adjacent to the chain guide member (510) among the first rail structures (227) may be omitted. In one embodiment, referring to FIGS. 14 and 15, the chain guide member (510) may include a second rail structure (500) (e.g., a rail, a guide block, and / or the second rail structure (300) of FIG. 7a, the second rail structure (400) of FIG. 11a) that replaces the omitted first rail structure (227). The second rail structure (500) may extend in the sliding direction (e.g., ±y axis direction) of the electronic device (200). In one embodiment, the second rail structure (500) may extend from the first housing (210) to the second housing (220). In one embodiment, the second rail structure (500) may face a side (e.g., a third side (2113)) of the first housing (220). In some embodiments, when the chain guide member (510) faces the second side (2112) of the first housing (210), the second rail structure (500) may face the second side (2112) of the first housing (210). In one embodiment, the second rail structure (500) may be received in a recess (527) formed in a rail member (526) in which at least a portion is disposed in the first housing (210). In one embodiment, the rail member (526) may be secured by being coupled to a support bracket (225). In some embodiments, the rail member (526) may be secured by being coupled to a first side member (211).In one embodiment, the chain member (520) can move in a sliding direction along the rail (511) of the chain guide member (510) based on the driving of the drive motor (260). The support bracket (225) can move in a sliding direction together with the chain member (520) as it is coupled with the chain fixing part (521) located at the end of the chain member (520). Based on the movement of the support bracket (2250), the first housing (210) can move in a sliding direction relative to the second housing (220). The rail member (526) can move in a sliding direction relative to the second housing (220) together with the first housing (210) as it is fixed to the support bracket (225) and / or the first side member (211) of the first housing (210). The rail member (526) can guide the movement of the first housing (210) relative to the second housing (220) as it moves along the second rail structure (500) of the chain guide member (510). Meanwhile, a sliding structure (226) may be disposed on the second side (2112) of the first housing (210), and a first rail structure (227) may be disposed on the fifth side (2212) of the second housing (220) so as to be linearly movable with respect to the sliding structure (226). Accordingly, the first housing (210) can move linearly relative to the second housing (220) based on the linear movement of the sliding structure (226) relative to the first rail structure (227) (e.g., movement in the Y-axis direction of FIG. 10a) and the linear movement of the rail member (526) relative to the second rail structure (500).

[0141] According to various embodiments, as illustrated in FIGS. 14 and 15, the second rail structure (500) may include a first guide groove (501) formed along the sliding direction (e.g., ±y axis direction) or movement direction of the electronic device (200). In one embodiment, the rail member (526) may include a second guide groove (528) facing the first guide groove (501) and corresponding to the first guide groove (501). In one embodiment, the second guide groove (528) may be located inside the recess (527) and formed on a surface facing the surface of the second rail structure (500) where the first guide groove (501) is formed. In one embodiment, a bearing member (b) (e.g., a bearing ball) that guides the sliding (e.g., movement) of the rail member (526) relative to the second rail structure (500) may be disposed between the first guide groove (501) of the second rail structure (500) and the second guide groove (528) of the rail member (526). In one embodiment, the first guide groove (501) and the second guide groove (528) may be formed with a shape in which at least a portion corresponds to the bearing member (b). The bearing member (b) may be disposed between the rail member (526) and the second rail structure (500) in the recess (527) of the rail member (526) to guide the sliding of the rail member (526) relative to the second rail structure (500).

[0142] According to various embodiments, as illustrated in FIGS. 14 and 15, the bearing member (b) may be positioned at a designated location (e.g., a first guide groove (501)) of the second rail structure (500) through a bearing fixing member (270) (e.g., a moving member, a sliding member). The bearing fixing member (270) may prevent the bearing member (b) from disengaging from the first guide groove (501) of the second rail structure (500). The bearing fixing member (270) may slide on the second rail structure (500) through the bearing member (b). In one embodiment, at least a portion of the bearing fixing member (270) may be positioned inside a recess (527) of the rail member (526).

[0143] In one embodiment, a lubricant such as grease may be applied to the recess (527) of the rail member (526). Thus, when the rail member (526) moves relative to the second rail structure (500), friction caused by contact between the rail member (526) and the second rail structure (500) can be reduced.

[0144] In a comparative embodiment, first rail structures (227) (e.g., the first rail structures (227) of FIG. 4a) may be disposed on the sides of the second housing (220) (e.g., the fifth side (2212), the sixth side (2213)). According to one embodiment of the present disclosure, among the first rail structures (227), the first rail structure (227) disposed adjacent to the chain guide member (510) may be omitted. For example, the first rail structure (227) may not be coupled to the sixth side (2213) of the second housing (220). In this case, compared to the case where the first rail structure (227) adjacent to the chain guide member (510) is disposed on the side of the second housing (220), the embodiment of FIG. 13 through 15 has the first rail structure (227) adjacent to the chain guide member (510) omitted, so the first rail Additional space can be secured on the left and right sides of the chain guide member (510) by the amount of space for the placement of the structure (227). Accordingly, the size of the battery (B) can be expanded by the amount of space created by omitting the first rail structure (227) adjacent to the chain guide member (510). As additional space is secured for the placement of the battery (B), the size of the battery can be increased, thereby increasing the capacity of the battery (B).

[0145] According to one embodiment of the present disclosure, an electronic device (101, 200) may include a flexible display (230). The electronic device may include a first housing (210).
