The position at which the first gear (421) and the first pattern (4311) engage may be spaced apart from the position at which the second gear (422) and the second pattern (4321) engage by the gap (G2). The drive assembly (400) according to an embodiment of the present disclosure can form a gap (G2) between the first pattern (4311) and the second pattern (4321) by the difference (G1) in diameters of the first gear (421) and the second gear (422) having different diameters, thereby forming a force that causes the pinion gear (420) and the rack gear (430) to mesh substantially uniformly on the first and second gears (421, 422). The drive assembly according to an embodiment of the present disclosure can also achieve the purpose through the above-described structure by forming a step by the gap (G2) between the first rack (431) and the second rack (432).

FIG. 13 is a drawing explaining the operation of the drive assembly (400) when the electronic device (101) changes from the state of FIG. 2 to the state of FIG. 3. The components explained with reference to FIG. 13 may be partly or entirely the same as the components explained with reference to FIGS. 1 to 12. The components explained with reference to FIG. 13 may be partly or entirely the same as the components explained with reference to FIGS. 14 to 21.

[0171] According to one embodiment, the first thrust (T1) for pulling out the second housing (202) when the second housing (202) starts to be pulled out from the first housing (201) may be greater than the second thrust (T2) for moving the second housing (202) after the second housing (202) is pulled out from the first housing (201). Since the electronic device according to the comparative embodiment moves the housing through a single pinion gear and a single rack gear, the driving of the drive assembly can be maintained at the first thrust (T1), which is the maximum value of the thrust for pulling out the second housing (202) when the second housing (202) starts to be pulled out from the first housing (201). The drive assembly (400) according to the embodiment of the present disclosure can adjust the size (F) of the drive thrust (T1, T2) by meshing gears (421, 422) having different diameters with rack gears (431, 432) according to the withdrawal state of the second housing (202) from the first housing (201).

[0172] In one embodiment, when the second housing (202) begins to be withdrawn from the first housing (201), the first gear (421) may engage the first-first pattern (4311a) within the first region (430a). When the second housing (202) begins to be withdrawn from the first housing (201), the second gear (422) may not engage the second rack (432). The drive assembly (400) may provide a first thrust (T1) greater than a second thrust (T2) to the housing (210).

[0173] In one embodiment, after the second housing (202) is withdrawn from the first housing (201), the second gear (422) may engage the second pattern (4321b) within the second region (430b). After the second housing (202) is withdrawn from the first housing (201), the first gear (421) may not engage the first rack (431).

The components explained with reference to FIG. 14 may be partly or entirely the same as the components explained with reference to FIGS. 1 to 13. The components explained with reference to FIG. 14 may be partly or entirely the same as the components explained with reference to FIGS. 15 to 21.

[0176] In one embodiment, the pinion gear (420) can move in the second direction (D2) along the rack gear (430). The first gear (421) can move in the second direction (D2) along the first rack (431). The second gear (422) can move in the second direction (D2) along the second rack (432).

[0177] According to one embodiment, the first thrust (T1) for retracting the second housing (202) when the second housing (202) starts to be retracted from the first housing (201) may be greater than the second thrust (T2) for moving the second housing (202) after the second housing (202) is retracted from the first housing (201). Since the electronic device according to the comparative embodiment moves the housings through a single pinion gear and a single rack gear, the drive assembly can be maintained driven by the first thrust (T1), which is the maximum value of the thrust for retracting the second housing (202) when the second housing (202) starts to be retracted from the first housing (201). The drive assembly (400) according to the embodiment of the present disclosure can adjust the size (F) of the drive thrust (T1, T2) by meshing gears (421, 422) having different diameters with rack gears (431, 432) according to the state of insertion of the second housing (202) from the first housing (201).

[0178] In one embodiment, when the second housing (202) begins to be pulled out from the first housing (201), the first gear (421) may engage the first-second pattern (4311c) within the third region (430c). When the second housing (202) begins to be pulled out from the first housing (201), the second gear (422) may not engage the second rack (432). The drive assembly (400) may provide a first thrust (T1) greater than a second thrust (T2) to the housing (210).

[0179] In one embodiment, after the second housing (202) is pulled out from the first housing (201), the second gear (422) may engage the second pattern (4321b) within the second region (430b). After the second housing (202) is pulled out from the first housing (201), the first gear (421) may not engage the first rack (431). The drive assembly (400) may provide a second thrust (T2) that is less than the first thrust (T1) to the housing (210).

[0180] According to one embodiment, when the second housing (202) is adjacent to the first housing (201) in a state where it is maximally retracted, the first gear (421) may engage the first-first pattern (4311a) within the first region (430a). When the second housing (202) is adjacent to the first housing (201) in a state where it is maximally retracted, the second gear (422) may not engage the second rack (432). The drive assembly (400) may provide a first thrust (T1) greater than a second thrust (T2) to the housing (210).

[0181] According to one embodiment, the drive assembly (400) can provide a first thrust (T1) or a second thrust (T2) to the housing (210) during operation. The thrust required to move the first housing (201) and the second housing (202) relative to each other may vary depending on the temperature state. For example, the first required thrust at a first temperature (e.g., -15 degrees Celsius) may be greater than the second required thrust at a second temperature (e.g., 0 degrees Celsius). The drive assembly (400) according to an embodiment of the present disclosure can stably move the housing (210) by providing the first and second thrusts (T1, T2) that are greater than the required thrusts (e.g., the first and second required thrusts) required at different temperature states (e.g., the first temperature (-15 degrees Celsius) or the second temperature (0 degrees Celsius)).
