As shown in fig. 4, an embodiment of the second aspect of the present invention provides an air deflector driving mechanism, including: a bracket 110, a movable member 200, and a driving device 300.

Specifically, the bracket 110 is provided with a plurality of positioning pillars 420; the movable piece 200 is provided with a guide groove 410, one end of the guide groove 410 is provided with a connecting structure 220 for connecting with the air deflector 500, the positioning column 420 extends into the guide groove 410 and is in sliding fit with the guide groove 410 to guide the movement of the movable piece 200, wherein the distribution density of the positioning column 420 is increased along the direction close to the connecting structure 220; the driving device 300 is connected to the movable member 200 or in transmission with the movable member 200, and is adapted to drive the movable member 200 to move.

Example 1:

as shown in fig. 3, in the present embodiment, the movable member 200 is provided with a plurality of positioning pillars 420, and the distribution density of the positioning pillars 420 is increased along a direction away from the connecting structure 220 on the movable member 200; the bracket 110 is provided with a guide groove 410, and the positioning column 420 extends into the guide groove 410 and is in sliding fit with the guide groove 410 to guide the movement of the movable element 200.

Further, a plurality of positioning columns 420 are arranged at intervals along the extending direction of the guiding groove 410, so that the degree of engagement between the sliding rail formed by arranging the plurality of positioning columns 420 and the guiding groove 410 is better, a better and more accurate guiding effect can be provided for the moving part 200, the movement precision of the moving part 200 is improved, and the opening and closing precision of the air deflector 500 is further improved. Further, the distribution density of the positioning pillars 420 is inversely related to the spacing between adjacent positioning pillars 420. That is, for an area where the positioning pillars 420 need to be densely distributed, the design requirement that the distribution density is relatively large can be correspondingly realized by controlling the smaller spacing between the adjacent positioning pillars 420 in the area, and for an area where the positioning pillars 420 need to be sparsely distributed, the design requirement that the distribution density is relatively small can be correspondingly realized by controlling the larger spacing between the adjacent positioning pillars 420 in the area, so that the design manner is also relatively simplified, and the product processing and production are more convenient.

For example, as shown in fig. 3, the guiding groove 410 is an arc-shaped groove extending along the M direction (specifically, for example, as shown by a dotted arrow in fig. 3). The number of the positioning pillars 420 is plural, and the positioning pillars 420 defining the arc shape are arranged in a single row at intervals along the M direction, and the connecting structure 220 is located at the end of the arc shape formed by the plurality of positioning pillars 420 along the M direction. More specifically, 11 positioning pillars 420 as shown in fig. 3 are disposed on the moving member 200, the 11 positioning pillars 420 are adjacent to each other in pairs, and a distance is provided between adjacent positioning pillars 420, here, since the sizes of the positioning pillars 420 are substantially the same, the distance between adjacent positioning pillars 420 is illustrated by a center distance between adjacent positioning pillars 420, the positioning pillars 420 are adjacent to each other in pairs to form center distances S1 to S10, and S1 to S10 are sequentially arranged along the M direction, so that S10 is closest to the connecting structure 220, and S1 is farthest from the connecting structure 220, wherein, optionally, from a value, a variation form of S1 to S10 is as follows:

example one:

S1-S10 are gradually increased in sequence, namely S1 < S2 < S3 … … S9 < S10.

Example two:

the gradient of S1 to S10 increases in an equal rule, for example, S1 to S5 are equal, S6 to S10 are equal, and the following conditions are satisfied: S1-S2-S3-S4-S5 < S6-S7-S8-S9-S10; for another example, S1 to S3 have the same value, S4 to S6 have the same value, S7 to S9 have the same value, and S1 ═ S2 ═ S3 < S4 ═ S5 ═ S6 < S7 ═ S8 ═ S9 < S10.

Example three:

s1 to S10 increase in an irregular gradient, for example, S1 to S3 are equal in value, S4 to S6 are not equal in value and gradually increase in sequence, S7 to S9 are equal in value, and S1 ═ S2 ═ S3 < S4 < S5 < S6 ═ S7 ═ S8 < S9 < S10.

Of course, it is understood that the number of the positioning pillars 420 is not limited to the illustrated 11, and in other implementations, the number may be more than 11, such as 15, 18, 20, etc., or may be slightly less than 11, such as 5, 6, 7, 8, 9, 10, etc., and those skilled in the art may flexibly set the number of the positioning pillars 420 according to specific requirements. It should be understood that there are many variations of the values of S1 to S10, and the variations are not limited to the above-illustrated forms, and those skilled in the art can select the specific distribution form of the positioning pillars 420 gradually sparsely arranged from S1 to S10 according to the requirement, which is not listed here, but all belong to the protection scope of the present disclosure without departing from the design concept.

The specific movement process is as follows:

referring to fig. 3, when the movable member 200 is fully retracted, the positioning pillars 420 are substantially located in the guiding grooves 410, that is, the number of the positioning pillars 420 in the guiding grooves 410 is maximum;

when the movable member 200 extends along the direction M, the number of the positioning pillars 420 reaching the outside of the guide groove 410 is gradually increased along with the increase of the extending length of the movable member 200, and accordingly, the number of the positioning pillars 420 in the guide groove 410 is reduced, which reduces the number of supporting points of the movable member 200 supported by the bracket 110.

When the movable member 200 retracts in the opposite direction of the direction M, the number of the positioning posts 420 in the guide groove 410 increases correspondingly with the movement of the movable member 200, so that the positioning posts 420 are arranged more sparsely, thereby ensuring the stability of the movable member 200 and reducing the movement resistance of the movable member 200.

Example 2:

as shown in fig. 4, in the present embodiment, the bracket 110 is provided with a plurality of positioning pillars 420, the movable element 200 is provided with a guiding groove 410, and the positioning pillars 420 extend into the guiding groove 410 and are in sliding fit with the guiding groove 410 to guide the movement of the movable element 200; wherein, one end of the guiding groove 410 is provided with the connecting structure 220, the other end of the guiding groove 410 is provided with an inlet for the positioning columns 420 to enter or leave the guiding groove 410, and for the plurality of positioning columns 420 on the bracket 110, the distribution density of the positioning columns 420 is increased along the direction close to the connecting structure 220 on the movable member 200.

It should be noted that, halfway, the semantic meaning of which is interpreted as anywhere between the starting point and the ending point, in the present design, one end of the air guiding wall 830 at the inlet 810 and one end of the air guiding wall 830 at the outlet 820 are understood as the starting point and the ending point, and halfway of the air guiding wall 830 is understood as any position on the air guiding wall 830 from one end of the air guiding wall 830 at the inlet 810 to one end of the air guiding wall 830 at the outlet 820, that is, halfway position of the air guiding wall 830 is not specific, and a person skilled in the art can flexibly select a specific halfway position of the air guiding wall 830 between one end of the air guiding wall 830 near the outlet 820 and one end near the inlet 810 according to requirements.

Wherein, the form of the air outlet position of the air duct 800 is adjusted to change the diversion form of the corresponding position, and then the air supply direction and angle are changed, the adjustment of the air supply direction and angle of the air conditioner is realized, and compared with the scheme of simply adjusting the air supply direction and angle by using the air deflector 500, the structure is more favorable for ensuring the uniformity of the air flow circulation area in the adjusting process, the adverse effect of huge loss of the air quantity is avoided, the problem of air guide dead angle of the air deflector 500 can be broken through, the adjusting range of the air supply direction and angle is more easily expanded to 0-90 degrees or even more than 90 degrees, the air supply range and angle are greatly expanded while the air supply loss is reduced. And in combination with the high stability and the large rotation range and stroke of the air deflector 500 realized by the air deflector driving mechanism in the design, the air deflector 500 can be more flexibly coordinated with the air outlet direction and angle of the air duct 800 to form combined air guiding of the air duct 800 and the air deflector 500, and certainly, under the condition that the air deflector 500 is not required to further guide air, the air deflector 500 can perfectly avoid the interference on the diversified air outlet direction and angle of the air duct 800 by utilizing the large rotation range and stroke realized by the air deflector 500, thereby avoiding the loss of air volume and air pressure and comprehensively improving the air exhaust effect of products.

Preferably, the deformable wall 832 comprises a flexible wall made of a flexible material, such that the flexible wall is formed by bending and deforming to change the flow guiding direction and angle thereof accordingly.

Alternatively, the flexible wall may be, for example, a metal sheet, a plastic sheet with some flexibility (e.g., a rubber sheet, etc.), or the like.

For example, as shown in fig. 10, the deformable wall 832 is substantially curved and arched upward and obliquely forward, and can guide the wind downward, so that the airflow maintains downward deflection force and inertia, and the wind is blown downward.

As shown in fig. 11, the deformable wall 832 is substantially in a straight shape extending forward and inclining downward, so as to realize straight flow guiding to the air flow obliquely forward and downward, and to exhaust air more efficiently.

As shown in fig. 12, the deformable wall 832 is substantially curved and arched backward and obliquely downward, so as to guide the wind forward and upward, so that the airflow maintains the deflecting force and inertia of the wind forward and obliquely upward, and the wind is blown forward for a long distance.

For example, for a volute duct, the volute wall is made integral with the deformable wall 832, and the volute tongue wall is made integral with the deformable wall 832.

Further, as shown in fig. 10 to 12, an end of the deformable wall 832 far from the outlet 820 is fixed, and an end thereof near the outlet 820 is a movable end, wherein the movable end moves to move the outlet 820 in the air outlet 750.

Upon actuation of the deformable wall 832, the deformable wall 832 deforms and swings about its fixedly disposed end, at which time the position of the movable end changes accordingly, causing a corresponding change in the position of the outlet 820.

In more detail, the ends of the

deformable walls

832A and 832B far from the outlet 820 are respectively provided with a fixing portion for fixedly mounting with the chassis 720, or a fixing portion for connecting with the fixing

walls

831A and 831B, such as lugs with through holes, for fixing the deformable walls 832 by screws.

Thus, in addition to changing the flow guiding shape of the deformable wall 832 (e.g., changing the bending direction of the deformable wall 832 to change the direction of the airflow inertia force) by changing the shape (e.g., changing the degree of flexure) of the deformable wall 832, the outlet 820 is further moved to change the wind outlet position. Thus, on the one hand, the adjustment range of the air supply direction and angle can be further expanded, and at the same time, the smoothness of the air flow inside the air duct 800 can be improved, and the uniformity of the flow area of the air duct 800 can be ensured, so as to reduce the air pressure and the air loss, for example, as shown in fig. 10, when the flexible wall is approximately in a curved shape that is inclined forward and arched upward, the outlet 820 is correspondingly moved backward and downward, so that the air flow direction and the outlet 820 are better adapted to each other, the air outlet resistance is smaller, and the air loss is smaller, as shown in fig. 11, when the flexible wall is approximately in a straight line shape that extends forward and inclines downward, the outlet 820 is obliquely arranged and faces the flow space formed by the flexible wall, so that the air flow direction and the outlet 820 are better adapted to each other, the air outlet resistance is smaller, and the air loss is smaller, as shown in fig. 12, when the, make export 820 roughly level forward, like this, the air current direction is better with export 820 orientation looks adaptability, and the air-out resistance is littleer, and the amount of wind loss is littleer, so, has realized reducing the purpose of wind pressure and amount of wind loss. On the other hand, the wind outlet position can be changed to conform to the shape change of the deformable wall 832, so that the internal stress of the deformable wall 832 can be reduced, and the damage risk of the deformable wall 832 is reduced.
