In the first embodiment, the panel assembly 200 is pivotably disposed on the exterior of the body casing. The drive assembly 300 is preferably a panel assembly moving component. When the air conditioner is in an operating state, the driving assembly 300 drives the panel assembly 200 to expose the air outlet assembly 100 . When the air conditioner stops operating, the drive assembly 300 drives the panel assembly 200 to close, and moves toward the body casing until it contacts the body casing.

5, when the panel assembly 200 is opened and closed, there is a gap H between the panel assembly 200 and the body casing, and in a typical design, the gap H is about 5-10 mm, that is, The panel assembly 200 and the body casing are in a detached state. As shown in FIG. 6 , the panel assembly 200 is in contact with the body casing, and the panel assembly 200 and the body casing are in an attached state, and in this case, the gap H is 0 mm.

With respect to the air conditioner, when the air conditioner stops operating, the drive assembly 300 may drive the panel assembly 200 to close and move toward the body casing until it contacts the body casing. Accordingly, there is no gap between the panel assembly 200 and the body casing, so that the air conditioner has a better appearance, and dust can be prevented from entering the air conditioner.

7 , 11 , and 12 , in one embodiment, the drive assembly 300 may include a first drive member 310 , a first gear 320 , and a first rack 330 . have. Here, the first driving member 310 drives the first gear 320 to rotate. The first rack 330 is engaged with the first gear 320 and is connected to the panel assembly 200 . The first gear 320 drives the first rack 330 to move. As a result, the first rack 330 drives the panel assembly 200 to move toward or away from the body casing.

The rotation shaft of the first driving member 310 is embedded in the first gear 320 , so that the first gear 320 may be driven to rotate. The first driving member 310 may drive the first gear 320 to rotate according to pre-determined programs. In one embodiment, the first driving member 310 may be a first stepping motor. The rotation shaft of the first stepping motor is driven to rotate the first gear 320 .

A steel ball 353 is disposed between the outer track 351 and the inner track 352 . Thus, as the panel assembly 200 moves towards or away from the body casing, the outer track 351 and the inner track 352 move relative to each other via the steel ball 353 . The relative movement between the outer track 351 and the inner track 352 is achieved by rolling of the steel ball 353 . Accordingly, the slide rail assembly 350 can significantly reduce frictional force generated when the first mount 341 and the second mount 342 move with respect to each other.

In the above embodiment, there may be a plurality of steel balls 353 . The plurality of steel balls 353 are uniformly distributed between the outer track 351 and the inner track 352 , thereby making the relative movement between the outer track 351 and the inner track 352 more stable.

Preferably, in order to prevent the steel ball 353 from being separated during rolling, the slide rail assembly 350 may further include a position-limiting structure 354 . The position limiting structure 354 is disposed between the inner track 352 and the outer track 351 . For example, the position limiting structure 354 may be disposed on the inner track 352 or the outer track 351 . The position limiting structure 354 limits the movement area of the steel ball 353 . In one embodiment, there are a plurality of position limiting structures 354 , the plurality of position limiting structures 354 being respectively disposed at both ends of the inner track 352 or at both ends of the outer track 351 . Due to this, the moving area of the steel ball 353 forms a closed space, so that the separation of the steel ball 353 between the outer track 351 and the inner track 352 can be better prevented.

In addition, in another embodiment, the outer track 351 may be connected to the first mount 341 , and the inner track 352 may be connected to the second mount 342 . The above connection method also enables the slide rail assembly 350 to obtain an effect of reducing frictional force generated when the first mount 341 and the second mount 342 move with respect to each other.

The slide rail assembly 350 has a relatively simple and stable structure. Of course, in other embodiments, the first degree of freedom moving structure may apply other structures.
