[221] The operation or arrangement of the components when the electronic device 400changes from the closed state to opened state is described with reference to FIGS. 7A to 10B.

[222] According to an embodiment, the motor 450 may rotate in one direction, and thefirst gear portion 471 connected to the motor 450 may be rotated in the one direction.

[223] According to an embodiment, the 1-1th gear 471c of the first gear portion 471may be connected to the 2-1th gear 473e of the second gear portion 473, and the second gearportion 473 may be rotated in the other direction opposite to the one direction.

[224] According to an embodiment, the 2-2th gear 473c of the second gear portion 473may be connected to the 3-1th gear 475g of the third gear portion 475. According to anembodiment, as the switch portion 457 pressurizes at least a portion of the first circular plate475f of the third gear portion 475 in the third sliding direction (e.g., the -X direction of FIGS. 9Ato 9C), the 3-1th gear 475g may be inserted into the second insertion portion 473d of the secondgear portion 473 and be connected with the 2-2th gear 473c. According to an embodiment, thethird gear portion 475, along with the second gear portion 473, may be rotated in the otherdirection.

[225] According to an embodiment, in the third gear portion 475, the 3-2th gear 475cmay be connected to the rack gear 477. According to an embodiment, as the 3-2th gear 475c isrotated on the rack gear 477, the rack gear 477 may be slid in the first sliding direction (e.g., the+Y direction of FIGS. 9A to 9C). In an embodiment, since the rack gear 477 is fixed to the firstplate 411, the first plate 411, along with the rack gear 477, may slide in the first sliding direction.In an embodiment, as the first plate 411 slides in the first sliding direction, which is a directionaway from the guide frame 425, the electronic device 400 may be changed from the closed state(e.g., FIG. 2A or 9A) to the opened state (e.g., FIG. 2B or 9B).

[226] According to an embodiment, the driving force of the motor 450 may betransferred to the first plate 411 through the first gear portion 471, the second gear portion 473,the third gear portion 475 and the rack gear 477.

[227] The operation or arrangement of the components when the electronic device 400changes from the opened state to closed state is described with reference to FIGS. 7A to 10B.

[228] According to an embodiment, the motor 450 may rotate in the other direction, andthe first gear portion 471 connected to the motor 450 may be rotated in the other direction.

[229] According to an embodiment, the 1-1th gear 471c of the first gear portion 471may be connected to the 2-1th gear 473e of the second gear portion 473, and the second gearportion 473 may be rotated in the one direction opposite to the other direction.

[230] According to an embodiment, the 2-2th gear 473c of the second gear portion 473may be connected to the 3-1th gear 475g of the third gear portion 475. According to anembodiment, as the switch portion 457 pressurizes at least a portion of the second circular plate475h of the third gear portion 475 in the third sliding direction (e.g., the -X direction of FIGS.9A to 9C), the 3-1th gear 475g may be inserted into the second insertion portion 473d of thesecond gear portion 473 and be connected with the 2-2th gear 473c. According to anembodiment, the third gear portion 475, along with the second gear portion 473, may be rotatedin the one direction.

[231] According to an embodiment, in the third gear portion 475, the 3-2th gear 475cmay be connected to the rack gear 477. According to an embodiment, as the 3-2th gear 475c isrotated on the rack gear 477, the rack gear 477 may be slid in the second sliding direction (e.g.,the -Y direction of FIGS. 9A to 9C). In an embodiment, since the rack gear 477 is fixed to thefirst plate 411, the first plate 411, along with the rack gear 477, may slide in the second slidingdirection. In an embodiment, as the first plate 411 slides in the second sliding direction, which isa direction closer to the guide frame 425, the electronic device 400 may be changed from theopened state (e.g., FIG. 2B or 9B) to the closed state (e.g., FIG. 2A or 9A).

[232] According to an embodiment, the driving force of the motor 450 may betransferred to the first plate 411 through the first gear portion 471, the second gear portion 473,the third gear portion 475 and the rack gear 477.

[233] If the electronic device 400 is dropped while the electronic device 400 is in theopened state (e.g., FIG. 2B or FIG. 9B), the electronic device 400 collides with the ground or thefloor, so that an external impact from the ground is applied to the electronic device 400. Forexample, if the electronic device 400 collides with the ground while the electronic device 400 isin the opened state, an external impact may be applied to the first housing 401 or the secondhousing 402 of the electronic device 400. Due to the external impact, the electronic device 400may be unintentionally changed from the opened state to the closed state. In this case, if the firsthousing 401 or the second housing 402 is rapidly slid with respect to each other, the rack gear477 may also be slid. The motor 450 may have a back-drive force in a stopped state, so that thefirst gear portion 471 may remain in a state not to be rotated. Accordingly, the second gearportion 473 connected to the first gear portion 471 and the third gear portion 475 connected tothe second gear portion 473 may also remain in a state not to be rotated. In this case, if the rackgear 477 is momentarily slid, an external impact may be applied to the third gear portion 475,which is not to be rotated, through the rack gear 477, so that the rack gear 477 or the 3-2th gear475c of the third gear portion 475 may be broken or the 3-1th shaft portion 475a or the 3-2thshaft portion 475d of the third gear portion 475 may be warped.

[234] According to various embodiments, the electronic device 400 may disconnect thesecond gear portion 473 and the third gear portion 475 from each other, thereby restricting theoccurrence of breakage or damage to the components when external impact is applied to theelectronic device 400.

[235] Hereinafter, a state in which the second gear portion 473 is disconnected from thethird gear portion 475 is described with reference to FIGS. 7A to 7H and FIGS. 11A and 11B.

[236] According to various embodiments, as the switch portion 457 slides in the fourthsliding direction (e.g., the +X direction of FIG. 11B), the driving member 455 may pressurize atleast a portion of the second circular plate 473h of the third gear portion 475 in the fourth slidingdirection (e.g., the +X direction of FIG. 11B). According to an embodiment, the third gearportion 475 may be slid in the fourth sliding direction (e.g., the +X direction of FIG. 11B), sothat the 3-1th gear 475g of the third gear portion 475 and the 2-2th gear 473c of the second gearportion 473 may be disconnected from each other.

[237] According to an embodiment, in a state in which the second gear portion 473 andthe third gear portion 475 are disconnected from each other, the motor 450 may not bedynamically connected with the rack gear 477.

[238] According to an embodiment, when external impact is applied to the electronicdevice 400, the rack gear 477 may be slid, and the third gear portion 475 connected with the rackgear 477 may be rotated by the rack gear 477.

[239] According to an embodiment, when the third gear portion 475 is disconnectedfrom the second gear portion 473, the back drive force of the motor 450 does not work, and thethird gear portion 475 may be naturally rotated by the rack gear 477. In an embodiment, whenthe rack gear 477 is slid, the third gear portion 475 is naturally rotated. Thus, it is possible toprevent the rack gear 477 or the 3-2th gear 475c of the third gear portion 475 from being brokenor the 3-1th shaft portion 475a or 3-2th shaft portion 475d of the third gear portion 475 fromwarping.

[240] According to an embodiment, the rack gear 477 may have a width (e.g., the widthin the X-axis direction of FIG. 11B) based on the sliding distance of the 3-2th gear 475c. Forexample, when the third gear portion 475 slides in the third sliding direction (e.g., the -Xdirection of FIG. 11B) or the fourth sliding direction (e.g., the +X direction of FIG. 11B), therack gear 477 may have a width at which at least a portion of the 3-2th gear 475c remainsconnected to the rack gear 477.

[241] According to an embodiment, when the third gear portion 475 is rotated, the thirdgear portion 475 is disconnected from the second gear portion 473. Thus, the 3-1th shaft portion475a of the third gear portion 475 is freely rotated on the through portion 473b of the secondgear portion 473, so that the second gear portion 473 may not be rotated together.

[242] According to various embodiments, the electronic device 400 may further includea sensor module (e.g., the sensor module 176 of FIG. 1) and a processor (e.g., the processor 120of FIG. 1).

[243] According to an embodiment, the sensor module may include a pressure sensor ora gyro sensor.

[244] According to various embodiments, the processor of the electronic device 400may be configured to identify whether the electronic device 400 is dropped or is in a state ofnormal use through the information provided through the sensor module.

[245] According to an embodiment, when the electronic device 400 is identified asdropped, the processor of the electronic device 400 may stop the operation of the motor 450while cutting off the power to the solenoid 456. According to an embodiment, when theoperation of the motor 450 is stopped, the motor 450 may form a back drive force. In anembodiment, when the power to the solenoid 456 is cut off, the switch portion 457 may be slid inthe fourth sliding direction (e.g., the +X direction of FIG. 11B) by the return spring, pressurizingthe second circular plate 475h in the fourth sliding direction.

[246] According to an embodiment, as the third gear portion 475, along with the secondcircular plate 475h, is slid in the fourth sliding direction, the 3-1th gear 475g may be spacedapart from the 2-2th gear 473c. For example, the 3-1th gear 475g and the 2-2th gear 473c may bedisconnected from each other.

[247] According to an embodiment, if the electronic device 400 hits the ground or floorin a state in which the third gear portion 475 and the second gear portion 473 are disconnectedfrom each other, the rack gear 477 or the third gear portion 475 may be prevented from beingdamaged.

[248] According to an embodiment, upon identifying that the drop of the electronicdevice 400 ends or that the electronic device 400 is in the state of normal use, the processor ofthe electronic device 400 may supply power to the solenoid 456, allowing the switch portion 457and the third gear portion 475 to slide in the third sliding direction (e.g., the -X direction of FIG.11B). According to an embodiment, the processor of the electronic device 400 may control therotation of the motor 450 in one direction or the other direction, thereby controlling the operationof the electronic device 400 so that the electronic device 400 is changed into the opened state orthe closed state.

[249] According to another embodiment (not shown), the motor 450 may be disposedadjacent to one side (e.g., the portion facing in the +X direction of FIG. 9C) of the gear frame430, and the driving member 455 may be disposed adjacent to the other side (e.g., the portionfacing in the -X direction of FIG. 9C) facing in the direction opposite to the one side of the gearframe 430. For example, the motor 450 and the driving member 455 may be disposed in oppositedirections, with the gear frame 430 disposed therebetween. According to another embodiment,the switch portion 457 of the driving member 455 may be connected to at least a portion of thethird gear portion 475. According to another embodiment, the first circular plate 475f and thesecond circular plate 475h may be disposed on the 3-2th shaft portion 475d, and the switchportion 457 of the driving member 455 may be inserted between the first circular plate 475f andthe second circular plate 475h. According to another embodiment, the 3-1th gear 475g of thethird gear portion 475 may be formed on a separate circular plate (not shown) which is disposedon the 3-1th shaft portion 475a and be connected to or disconnected from the 2-2th gear 473c ofthe second gear portion 473. According to another embodiment, upon identifying that the drop ofthe electronic device 400 is ended or that the electronic device 400 is in the state of normal use,the processor of the electronic device 400 may cut off the power to the solenoid 456. Accordingto another embodiment, when the power to the solenoid 456 is cut off, the switch portion 457may be slid by the return spring of the solenoid 456 in the third sliding direction (e.g., the -Xdirection of FIG. 9C), and the 3-1th gear 475g of the third gear portion 475 may be connected tothe 2-2th gear 473c of the second gear portion 473. According to another embodiment, uponidentifying that the electronic device 400 is dropped, the processor of the electronic device 400may supply power to the solenoid 456. According to another embodiment, when power issupplied to the solenoid 456, the switch portion 457 may be slid by the plunger of the solenoid456 in the fourth sliding direction (e.g., the +X direction of FIG. 9C), and the 3-1th gear 475g ofthe third gear portion 475 and the 2-2th gear 473c of the second gear portion 473 may bedisconnected from each other. According to another embodiment (not shown), the motor 450 anddriving member 455 of the electronic device 400 may be disposed adjacent to the other side (e.g.,the portion facing in the -X direction of FIG. 9C) of the gear frame 430. According to anembodiment, when the electronic device 400 is detected as being in a first mode (or normalmode) (e.g., a mode, not an impact detection mode, or a normal use mode) through the processorand the sensor module, the electronic device 400 may control the solenoid 456 to connect the 3-1th gear 475g of the third gear portion 475 and the 2-2th gear 473c. In an embodiment, the firstmode may be defined and interpreted as when the electronic device 400 is detected as being in astate different from the second mode. For example, the first mode may be the case where theelectronic device 400 is detected as being in a state different from the second mode (e.g., thestate in which the electronic device 400 is dropped), and the other state may be a normal usestate of the electronic device 400 or a state in which the drop of the electronic device 400 isended.

[250] According to an embodiment, when the electronic device 400 is detected as beingin the second mode (or impact detection mode) (e.g., when the electronic device 400 is detectedas being dropped or falling) through the processor and the sensor module, the electronic device400 may control the solenoid 456 to disconnect the 3-1th gear 475g of the third gear portion 475and the 2-2th gear 473c. For example, the second mode may be defined and interpreted as amode different from the first mode.
