The sliding column 204 is slidably connected to the first track groove 102 through the first track groove 102, and a movement track of the sliding column 204 is defined by the first track groove 102. The sliding column 204 is embedded into the first track groove 102 and partially protrudes from the first track groove 102, which is helpful to make the top of the swing blade close to the inner wall of the air-out frame 10, reduce the gap between the top and the bottom of the swing blade and the air-out frame 10 as much as possible, and reduce air leakage.

The end of the sliding column 204, i.e. the sliding column 204, is arranged through and protrudes out of the first track groove 102. The end of the spool 204 is provided with a stopper 205, and when the spool 204 is inserted into the first track groove 102, the stopper 205 prevents the spool 204 from coming off the first track groove 102. Wherein, under the condition that the sliding column 204 is arranged at the top of the swing vane, the limiting part 205 can also be lapped on the first track part 101, and the top of the first track part 101 and the top of the air-out frame 10 play a certain role in bearing.

Optionally, the stop portion 205 is removably coupled to the spool 204. For example, the stop 205 may be threaded onto the top of the spool 204. The cross-sectional area of the limiting portion 205 is larger than that of the spool 204.

Optionally, the swing blade assembly 20 includes a first swing blade 206, an intermediate swing blade group 207, and a second swing blade 208, which are sequentially arranged; the middle swinging blade group 207 comprises one or more swinging blades 201, and two opposite sides of each swinging blade are hinged with the adjacent swinging blades. As shown in connection with fig. 2.

In the case where the intermediate swing blade group 207 includes only one swing blade, for convenience of description, the swing blade of the intermediate swing blade group 207 is defined as an intermediate swing blade. The first swing blade 206, the middle swing blade and the second swing blade 208 are sequentially arranged and hinged, that is, the first swing blade 206 is hinged with a first edge of the middle swing blade, and the second swing blade 208 is hinged with a second edge of the middle swing blade. Wherein, the first edge and the second edge of the middle swinging vane are arranged oppositely. In this way, when the swing blade assembly 20 is slidably coupled to the first rail part 101 and folded, the first swing blade 206, the intermediate swing blade, and the second swing blade 208 are sequentially overlapped.

In the case that the middle blade set 207 includes a plurality of blades 201, opposite sides of each blade are hinged to the adjacent blades, that is, a first edge of each blade is hinged to the blade adjacent to the first edge of the blade, and a second edge is hinged to the blade adjacent to the second edge of the blade. In this way, when the swing blade assembly 20 is slidably connected to the first rail portion 101 and folded, the first swing blade 206, the plurality of swing blades 201 of the intermediate swing blade group 207, and the second swing blade 208 are sequentially overlapped.

The first swing blade 206 and the second swing blade 208 are outermost swing blades in the swing blade assembly 20, so that only one edge of the first swing blade 206 is hinged with an adjacent swing blade, and similarly, only one edge of the second swing blade 208 is hinged with an adjacent swing blade.

Optionally, the indoor unit further includes: and the driving mechanism is in transmission connection with the swing blade assembly 20 so as to drive the plurality of swing blades 201 in the swing blade assembly 20 to unfold or fold. The driving mechanism is in transmission connection with the swing blade assembly 20 to drive the plurality of swing blades 201 in the swing blade assembly 20 to unfold or fold.

Alternatively, a drive mechanism may be drivingly connected to each of the swing vanes in the swing vane assembly 20. Alternatively, the drive mechanism may be drivingly connected to the outermost wobble blade of the wobble blade assembly 20. I.e. the drive mechanism is in driving connection with the first pendulum blade 206 and/or the drive mechanism is in driving connection with the second pendulum blade 208. Alternatively, the driving mechanism may also be in transmission connection with a plurality of swing blades 201 in the remaining swing blades of the swing blade assembly 20 except the outermost swing blade.

In practical applications, in a case that the driving mechanism is only in transmission connection with the first swing blade 206, an edge of the second swing blade 208 may be relatively fixed to the air-out frame 10. Wherein the edge of the second swing blade 208 is an edge away from the adjacent swing blade. The driving mechanism drives the swing blades in the swing blade assembly 20 to unfold, that is, the first swing blade 206 drives the remaining swing blades of the swing blade assembly 20 to slide along the first track portion 101 until the swing blade assembly 20 is completely unfolded to close the air outlet 100 defined by the air outlet frame 10.

Optionally, the drive mechanism comprises: the gear 30 and the rack 40, the rack 40 is meshed with the gear 30, and the rack 40 is connected with at least the first swing blade 206; during the movement of the swing blade assembly 20, the rack 40 is driven by the gear 30 to drive the first swing blade 206 to move, so that the plurality of swing blades 201 of the swing blade assembly 20 are folded or unfolded. As shown in connection with fig. 1 to 3.

The gear 30 is driven by a motor to rotate, and the rack 40 is meshed with the gear 30, so that the gear 30 rotates to drive the rack 40 to move linearly. The rack 40 is connected to the first swing blade 206, and particularly, the rack 40 is fixedly connected to the sliding column 204 of the first swing blade 206. Thus, in the process of the movement of the rack 40, the rack 40 drives the first swing blade 206 to move, that is, the rack 40 drives the sliding column 204 of the first swing blade 206 to slide along the first track portion 101, so that the first swing blade 206 drives the remaining swing blades to unfold to close the air outlet 100 or the first swing blade 206 drives the remaining swing blades to fold with each other to open the air outlet 100.

The rack 40 is disposed along the first rail part 101 and moves along the first rail part 101 to define a movement trace of the strut 204, i.e., the plurality of swing vanes 201 are folded or unfolded.

In practical applications, the rack 40 is connected to one of the remaining flaps in addition to the first flap 206, wherein at least one flap is spaced between the flap connected to the rack 40 and the first flap 206. In this way, the two swing vanes are connected to the rack 40, so that the rack 40 can be supported, and the movement track of the rack 40 can be limited.

Optionally, the rack 40 comprises: a first connecting portion 401 connected to the strut 204 of the first swing blade 206; a second connecting portion 402 connected to the strut 204 of the third swing link 209; the third swing blade 209 is located in the middle swing blade group 207, and at least one swing blade is spaced between the third swing blade 209 and the first swing blade 206. As shown in connection with fig. 2 and 3.

The first connecting portion 401 is connected to the sliding column 204 of the first swing blade 206, wherein the first connecting portion 401 is detachably connected to the sliding column 204 of the first swing blade 206 for replacement and maintenance. The second connecting portion 402 is connected to the sliding column 204 of the third swing vane 209, wherein the second connecting portion 402 is detachably connected to the sliding column 204 of the third swing vane 209 for replacement and maintenance. In addition, the first swing vane 206 and the third swing vane 209 can support the rack 40, so that the rack 40 and the first rail portion 101 can be separated from each other, and the rack 40 and the first rail portion 101 are prevented from being in frictional contact in the movement process, so that loss and resistance are prevented.

The third swing blade 209 is located in the middle swing blade group 207, and at least one swing blade is spaced between the third swing blade 209 and the first swing blade 206. In this way, the first swing vane 206 and the third swing vane 209 help the rack 40 to be uniformly stressed during the movement of the rack 40.

In practical applications, the plurality of swing vanes 201 in the swing vane assembly 20 are divided into two groups, wherein the first swing vane 206 may be a first swing vane in the first group, and the third swing vane 209 may be a first swing vane in the second group. In this way, not only is the rack 40 uniformly stressed, but also the pulling force of the first swing blade 206 on the remaining swing blades can be reduced, and thus the movement of the plurality of swing blades 201 in the swing blade assembly 20 in the process of folding or unfolding is more stable.

Optionally, the rack 40 further comprises: an accommodating groove 403 provided between the first connecting portion 401 and the second connecting portion 402; the sliding column 204 of the swing blade between the third swing blade 209 and the first swing blade 206 is inserted into the accommodating groove 403. As shown in connection with fig. 3.

The rack 40 is an elongated and plate-like structure, and the rack 40 includes a first edge configured with teeth to engage with the gear 30 and a second edge. The first connecting portion 401 and the second connecting portion 402 may be two ends of the rack 40, and the receiving groove 403 is located between the first connecting portion 401 and the second connecting portion 402 and is formed in an inward recessed configuration from the second edge. Thus, the sliding column 204 of the swing blade between the first swing blade 206 and the third swing blade 209 can be inserted into the receiving slot 403 to prevent interference with the movement of the rack 40, thereby affecting the folding and unfolding of the swing blade assembly 20.

Optionally, the receiving groove 403 is located between the first connecting portion 401 and the second connecting portion 402, and is recessed to form a through groove and is disposed along the length direction of the rack 40. In this way, the sliding column 204 of the swing blade located between the first swing blade 206 and the third swing blade 209 is inserted into the accommodating groove 403, which not only can prevent interference with the movement of the rack 40, but also can define the movement track of the sliding column 204 of the swing blade located between the first swing blade 206 and the third swing blade 209 through the accommodating groove 403, so as to enable the plurality of swing blades 201 of the swing blade assembly 20 to be folded and unfolded better.

Alternatively, the rack 40 moves along the length direction of the first track groove 102, and the length of the rack 40 is smaller than the length of the first track groove 102. As shown in connection with fig. 1 to 3.

The rack 40 is disposed along the first rail part 101 and moves along the first rail part 101 to define a movement trace of the strut 204, i.e., the plurality of swing vanes 201 are folded or unfolded.

In the case where the length of the rack 40 is smaller than the length of the first rail groove 102, it is possible to avoid the movement of the rack 40 from being limited by space, i.e., insufficient movement stroke.

Alternatively, in the case where the length of the rack 40 is smaller than the length of the first track groove 102, the gear 30 is located at the middle of the first track groove 102. In this way, in the case that the gear 30 drives the rack 40 to move to the first side of the air-out frame 10, the plurality of swing vanes 201 of the swing vane assembly 20 are unfolded to close the air outlet 100. Under the condition that the gear 30 drives the rack 40 to move to the second side of the air outlet frame 10, the plurality of swing vanes 201 of the swing vane assembly 20 are folded to open the air outlet 100. Wherein, the first side and the second side of the air-out frame 10 are arranged oppositely.
