For example, the gear connection state may include a first gear connection state and a second gear connection state having a gear ratio greater than the first gear connection state. The gear ratio may correspond to the magnitude of the driving force of the pinion gear 462 that moves the rack gear 463. As the gear ratio of the switching structure 500 increases, the magnitude of the driving force of the pinion gear 462 that moves the rack gear 463 may increase. According to one embodiment, the gear ratio may be defined by the product of the number of gear teeth of each of the gears 521, 541, and 551 of the switching structure 500 disposed between the motor 461 and the pinion gear 462. there is.

The gear release state may be referred to as a neutral state in that power transmission between the motor 461 and the pinion gear 462 is blocked. For example, when the switching structure 500 is in the gear release state, the pinion gear 462 may not rotate due to the driving force of the motor 461 despite the operation of the motor 461. As another example, when the switching structure 500 is in the gear-disengaged state, the pinion gear 462 may be rotatable independently of the motor 461 .

As the third shaft 550 rotates, the pinion gear 462 connected to the third shaft 550 rotates, and the rack gear 463 may move with respect to the first housing 410. When the rack gear 463 moves, the second housing 420 connected to the rack gear 463 moves, allowing the display 430 to expand or contract.

According to one embodiment, the state of the switching structure 500 may change according to the movement of the cover housing 530 by the actuator 510. For example, when the cover housing 530 is moved by the actuator 510, the interlocking relationship of the gears 521, 541, and 551 in the switching structure 500 changes, and the state of the switching structure 500 changes.

According to one embodiment, the processor 470 may be configured to change the switching structure 500 to a geared state or a geared disengaged state via an actuator 510 based on identifying a designated event. For example, the processor 470 may be configured to change the switching structure 500 from a gear engaged state (e.g., a first gear engaged state or a second gear engaged state) to a gear disengaged state based on identifying a designated event. It can be configured. In another example, processor 470 changes switching structure 500 from a gear disengaged state to a gear engaged state (e.g., a first gear engaged state or a second gear engaged state) based on identifying a designated event. It can be configured to do so. As another example, processor 470 may, based on identifying a specified event, change switching structure 500 from a first gear engaged state to a second gear engaged state or from a second gear engaged state to a first gear engaged state.

For example, an abnormal state of the electronic device 400 may be when the electronic device 400 falls, when the electronic device 400 is in a low power state, or when the electronic device 400 is overheated. This may include a case where the electronic device 400 is exposed to a low temperature environment.

According to one embodiment, processor 470, through actuator 510, gears the state of switching structure 500 based on receiving user input requesting a change in the state of switching structure 500.

You can change from the connected state to the gear disengaged state. The first designated value may be set to correspond to the acceleration value obtained by the acceleration sensor 481 when the electronic device 400 falls. The processor 470 may identify that the electronic device 400 is falling based on identifying that the acceleration value obtained from the acceleration sensor 481 exceeds the first specified value. For another example, when the angular velocity value of the electronic device 400 obtained from the gyro sensor 482 exceeds the second specified value, the processor 470 operates the switching structure 500 through the actuator 510. You can change from the gear connected state to the gear disengaged state. The second designated value may be set to correspond to the angular velocity value obtained by the gyro sensor 482 when the electronic device 400 falls. Processor 470 may identify electronic device 400 as falling based on identifying that the angular velocity value obtained by gyro sensor 482 exceeds a second specified value. . For example, when the switching structure 500 is in a gear-connected state, the pinion gear 462 may rotate due to an impact generated when the electronic device 400 freely falls and collides with the ground. When the switching structure 500 is in a gear-connected state, the motor 461 and the pinion gear 462 are connected, so the driving force generated by the rotation of the pinion gear 462 can be transmitted to the motor 461. When the driving force generated by the rotation of the pinion gear 462 is transmitted to the motor 461, parts inside the motor 461 may be damaged.

The processor 470 may identify the electronic device 400 as being in a low-power state when the power amount of the battery 450 is less than a third specified value. For example, when the electronic device 400 is in a low power state, the power supplied to the motor 461 becomes insufficient, so the second housing 420 may not be moved by the motor 461. If the second housing 420 is manually moved by a user in a gear-connected state of the switching structure 500 in which the motor 461 and the pinion gear 462 are connected, internal parts of the motor 461 may be damaged. The electronic device 400 according to one embodiment is configured to change the switching structure 500 from the gear engaged state to the gear disengaged state when the electronic device 400 is in a low power state, and the motor 461 is operated by the processor 470.

Processor 470 may identify motor 461 as overheated based on identifying that the temperature obtained by first temperature sensor 483 exceeds a fourth specified value. For example, if the temperature of the motor 461 exceeds the fourth specified value, the processor 470, through the actuator 510, switches the switching structure 500 in the first gear engaged state to the first gear engaged state. It may be configured to change to a second gear connection state having a gear ratio greater than the state. As the switching structure 500 changes to the second gear connection state with a larger gear ratio, the load on the motor 461 decreases, so the temperature of the overheated motor 461 can be reduced. As another example, if the temperature of the motor 461 exceeds the fourth specified value, the processor 470, through the actuator 510, changes the switching structure 500 to a gear connection state (e.g., a first gear connection state). state or the second gear engaged state) may be configured to change to the gear disengaged state.

For example, the fifth designated value may be, but is not limited to, a temperature in degrees Celsius below -10°C. The processor 470 may identify the electronic device 400 as being exposed to a low-temperature environment based on identifying that the temperature of the display 430 is less than a fifth specified value. When the temperature of the display 430 is less than the fifth specified value, the driving force required to expand the display 430 may increase as the repulsive force of the display 430 increases. The electronic device 400 according to an embodiment includes a processor 470 configured to change the switching structure 500 from the first gear connected state to the second gear connected state when the temperature of the display 430 is less than a fifth specified value. By this, the display 430 can be smoothly expanded or contracted in a relatively low temperature environment.
