[0058] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0059] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.

[0060] The air guiding mechanism 100 according to the first aspect embodiment of the present invention will be described below with reference to the accompanying drawings.

[0061] As Figures 1 to 10As shown, the air guiding mechanism 100 according to the embodiment of the first aspect of the present invention includes: a louver assembly 1 and a driving assembly 2. The louver assembly 1 includes a louver link 11 extending along the first direction e1 and a plurality of air guiding louvers 12 rotatably connected to the louver link 11, and the louver link 11 is movable along the first direction e1. Among them, the louver link 11 is swingably arranged at the air outlet 210 of an air conditioning device such as an air conditioner 1000, and the plurality of air guiding louvers 12 are arranged along the first direction e1 and rotatably connected to the louver link 11. Therefore, the movement of the louver link 11 along the first direction e1 can drive the plurality of air guiding louvers 12 connected to the louver link 11 to swing at the air outlet 210, so as to adjust the deflection direction and angle of the air guiding louvers 12, and further adjust the air outlet direction by adjusting the deflection direction and angle of the air guiding louvers 12.

[0062] The driving assembly 2 is used to drive the louver link 11 to move and includes a driving unit 21 and a lever transmission unit 22. The lever transmission unit 22 is drivably connected between the driving unit 21 and the louver link 11, so that the driving unit 21 can drive the louver link 11 to move along the first direction e1 through the lever transmission unit 22 to adjust the deflection direction and angle of the air guiding louvers 12. The lever transmission unit 22 includes a first transmission rod 221, a second transmission rod 222 and a third transmission rod 223. The first transmission rod 221 has a support point and is rotatable around the support point. The second transmission rod 222 is drivably connected to the driving unit 21 and rotatably connected to the first transmission rod 221. The third transmission rod 223 is connected to the louver link 11 and rotatably connected to the first transmission rod 221. The fact that the second transmission rod 222 is drivably connected to the driving unit 21 means that the second transmission rod 222 can generate movement under the drive of the driving unit 21. Among them, the driving unit 21 can achieve transmission by being connected to the second transmission rod 222, and the driving unit 21 can also achieve transmission by being in contact and cooperation with the second transmission rod 222. In other words, it is only necessary that the driving unit 21 can drive the second transmission rod 222 to move, and the manner in which the driving unit 21 drives the second transmission rod 222 to move is not limited here.

[0063] That is to say, the driving unit 21 drives the second transmission rod 222 to move, driving the first transmission rod 221 to rotate around the support point. The rotation of the first transmission rod 221 drives the third transmission rod 223 to move, and then the movement of the third transmission rod 223 drives the louver connecting rod 11 to move, so as to adjust the deflection direction and angle of the air guiding louver 12. Thus, the first transmission rod 221, the second transmission rod 222 and the third transmission rod 223 together constitute a lever-type transmission method, which is beneficial to reducing the precision requirements for the lever transmission unit 22. The first transmission rod 221, the second transmission rod 222 and the third transmission rod 223 are all rotatably connected, which can better prevent the lever transmission unit 22 from jamming during the rotation of the first transmission rod 221 around the support point. Among them, in the extending direction of the first transmission rod 221, the distance between the second transmission rod 222 and the support point is less than the distance between the third transmission rod 223 and the support point. That is to say, in the extending direction of the first transmission rod 221, compared with the third transmission rod 223, the support point is arranged adjacent to the second transmission rod 222.

[0064] It can be understood that the driving unit 21 drives the second transmission rod 22 to move 2, driving the first transmission rod 221 to rotate around the support point. Therefore, in the extending direction of the first transmission rod 221, when the stroke of the third transmission rod 223 is fixed, the shorter the distance between the second transmission rod 222 and the support point, and the longer the distance between the third transmission rod 223 and the support point, the shorter the stroke required for the second transmission rod 222 to move. And, the stroke of the third transmission rod 223 is proportional to the stroke of the louver connecting rod 11. Thus, when the stroke of the louver connecting rod 11 is fixed, by setting the distance between the second transmission rod 222 and the support point to be less than the distance between the third transmission rod 223 and the support point, the stroke of the second transmission rod 222 can be better shortened, so that the moving range of the second transmission rod 222 can be reduced, and further the avoidance space reserved by the air guiding mechanism 100 for the movement of the second transmission rod 222 can be reduced, with a reasonable layout and a compact structure.

[0065] For the air guiding mechanism 100 according to the first aspect embodiment of the present invention, by setting the distance between the second transmission rod 222 and the support point to be less than the distance between the third transmission rod 223 and the support point, the stroke of the second transmission rod 222 can be better shortened, so that the moving range of the second transmission rod 222 can be reduced, and further the avoidance space reserved by the air guiding mechanism 100 for the movement of the second transmission rod 222 can be reduced, with a reasonable layout and a compact structure.

[0066] In a specific example, a rotating shaft 224 is provided on the first transmission rod 221, and the rotating shaft 224 constitutes the rotating support point of the first transmission rod 221.

[0067] According to some embodiments of the present invention, in the extending direction of the first transmission rod 221, the connection position of the second transmission rod 222 and the first transmission rod 221 is located on one side of the support point, and the connection position of the third transmission rod 223 and the first transmission rod 221 is located on the other side of the support point. That is to say, the connection position of the second transmission rod 222 and the first transmission rod 221 and the connection position of the third transmission rod 223 and the first transmission rod 221 are respectively located on the opposite sides of the support point in the extending direction of the first transmission rod 221. Thus, the distance between the connection position of the second transmission rod 222 and the first transmission rod 221 and the connection position of the third transmission rod 223 and the first transmission rod 221 can be preferably increased, so that the second transmission rod 222 and the third transmission rod 223 can be preferably prevented from interfering with each other during the movement, which is beneficial to improving the reliability and stability of the transmission of the lever transmission unit 22. In a specific example, in the extending direction of the first transmission rod 221, the second transmission rod 222 is rotatably connected to one end of the first transmission rod 221, the third transmission rod 223 is rotatably connected to the other end of the first transmission rod 221, and the support point is located between the two ends of the first transmission rod 221, so that the installation space on the first transmission rod 221 can be fully utilized, which is beneficial to shortening the length of the first transmission rod 221 to reduce the installation space required for the installation and movement of the first transmission rod 221.

[0068] According to some embodiments of the present invention, in the extending direction of the first transmission rod 221, the distance L1 between the second transmission rod 222 and the support point and the distance L2 between the third transmission rod 223 and the support point satisfy: 2 / 5 ≤ L1 / L2 ≤ 2 / 3. That is, the ratio of the distance between the second transmission rod 222 and the support point to the distance between the third transmission rod 223 and the support point is controlled within the range of 2 / 5 to 2 / 3. For example, the ratio of the distance between the second transmission rod 222 and the support point to the distance between the third transmission rod 223 and the support point can be 2 / 5, or 9 / 20, or 1 / 2, or 7 / 12, or 2 / 3, etc., without specific limitation here. Among them, when the stroke of the third transmission rod 223 is fixed, the smaller the ratio of the distance between the second transmission rod 222 and the support point to the distance between the third transmission rod 223 and the support point, the shorter the distance between the second transmission rod 222 and the support point. When the stroke of the third transmission rod 223 is fixed, the shorter the stroke required for the second transmission rod 222, and at the same time, the shorter the power arm when the first transmission rod 221 rotates, and the greater the driving force required to be output by the driving unit 21. Therefore, by controlling the ratio of the distance between the second transmission rod 222 and the support point to the distance between the third transmission rod 223 and the support point within the range of 2 / 5 to 2 / 3, the risk of interference between the support point and the second transmission rod 222 caused by too short a distance between the second transmission rod 222 and the support point can be prevented, the requirement for the driving force output by the driving unit 21 during the rotation of the first transmission rod 221 can be reduced, and at the same time, the risk of too long a distance between the second transmission rod 222 and the support point resulting in too long a stroke required for the second transmission rod 222 to meet the stroke of the third transmission rod 223 can be prevented. Thus, while avoiding interference between the support point and the second transmission rod 222 and reducing the requirement for the driving force output by the driving unit 21 by the lever transmission unit 22, the stroke of the second transmission rod 222 can be shortened, which is beneficial to improving the compactness of the air guiding mechanism 100.

[0069] According to some embodiments of the present invention, both the second transmission rod 222 and the third transmission rod 223 extend along the first direction e1 and are movable along the first direction e1, and the rotation axis of the first transmission rod 221 extends along the second direction, and the second direction is perpendicular to the first direction e1. That is to say, the driving unit 21 is used to drive the second transmission rod 222 to move along the first direction e1, and the first transmission rod 221 is pushed by the second transmission rod 222 to rotate around the second direction, and then the first transmission rod 221 drives the first transmission rod 221 to move along the first direction e1 and finally drives the louver link 11 to move along the first direction e1 and in a direction opposite to the movement of the second transmission rod 222 to adjust the deflection direction and angle of the air guiding louvers 12. Thus, the consistency of the moving directions of the third transmission rod 223 and the louver link 11 can be better ensured, and the second transmission rod 222 only needs to move along the first direction e1, which is beneficial to reducing the difficulty of driving the second transmission rod 222 to move by the driving unit 21.

[0070] According to some embodiments of the present invention, the driving unit 21 includes a driving member 211 and a transmission base 212. A mating track 2121 is formed on the transmission base 212. One end of the second transmission rod 222 is in contact and cooperation with the mating track 2121. The driving member 211 is used to drive the transmission base 212 to move, so that the second transmission rod 222 moves along the extension direction of the mating track 2121 relative to the mating track 2121. During the movement of the transmission base 212, the transmission base 212 drives the second transmission rod 222 to move along the first direction e1. That is to say, the second transmission rod 222 realizes the transmission connection with the transmission base 212 through the contact and cooperation with the mating track 2121. That is, the lever transmission unit 22 is in transmission connection with the driving unit 21 in a contact and cooperation manner, which can preferably simplify the cooperation mode between the lever transmission unit 22 and the driving unit 21, and can eliminate the connection structure between the lever transmission unit 22 and the driving unit 21.

[0071] According to some embodiments of the present invention, the surface of the second transmission rod 222 in contact with the mating track 2121 is a contact surface, and the contact surface is formed as an arc surface. Thereby, the friction between the contact surface and the mating track 2121 can be preferably reduced, so that the situation of jamming can be avoided during the movement of the second transmission rod 222 along the mating track 2121, and further ensure that the second transmission rod 222 can slide smoothly along the mating track 2121, which is beneficial to improving the stability and reliability of the cooperation between the transmission base 212 and the second transmission rod 222. In a specific example, the cross-section of the part of the mating track 2121 in contact with the contact surface in the extension direction of the mating track 2121 is a concave arc.

[0072] According to some embodiments of the present invention, the wall surface of the mating track 2121 in contact with one end of the second transmission rod 222 is a mating surface, and in the extension direction of the mating track 2121, the mating surface extends in a wavy shape. That is to say, in the extension direction of the mating track 2121, the mating surface is composed of a plurality of sequentially undulating waveforms. Therefore, when the second transmission rod 222 moves from the wave crest to the adjacent wave trough, the second transmission rod 222 moves along the first direction e1 towards the direction close to the transmission base 212. When the second transmission rod 222 moves from the wave trough to the adjacent wave crest, the second transmission rod 222 moves along the first direction e1 towards the direction away from the transmission base 212. Thereby, by the cooperation of the second transmission rod 222 and the wavy mating surface, the position of the second transmission rod 222 in the first direction e1 can be preferably adjusted, and then the position of the louver link 11 in the first direction e1 can be adjusted through the first transmission rod 221 and the third transmission rod 223 to change the deflection direction and deflection angle of the air deflector louver 12.

[0073] In addition, by setting the distance between the second transmission rod 222 and the support point to be less than the distance between the third transmission rod 223 and the support point, the stroke of the second transmission rod 222 can be preferably shortened. It can be understood that the stroke of the second transmission rod 222 in the first direction e1 is the distance between the peak and valley of the mating surface in the first direction e1, that is, the height of the wave of the wavy mating surface. Thus, by shortening the stroke of the second transmission rod 222, the distance between the peak and valley in the first direction e1 can be preferably shortened, so that the undulation degree of the mating surface in the extending direction of the mating track 2121 can be preferably reduced. Furthermore, it can be avoided that the second transmission rod 222 is jammed with the mating track 2121 due to excessive undulation of the mating surface, which is beneficial to improving the stability of the cooperation between the second transmission rod 222 and the transmission seat 212.

[0074] It should be noted that the stroke of the second transmission rod 222 in the first direction e1 can be controlled by controlling the distance between the peak and valley of the mating surface in the first direction e1, that is, the wave height, so as to realize the stroke range of the louver link 11 in the first direction e1. Specifically, when the stroke requirement of the louver link 11 in the first direction e1 is 20 mm, that is, the stroke requirement of the third transmission rod 223 in the first direction e1 is 20 mm, the distance between the third transmission rod 223 and the support point in the extending direction of the first transmission rod 221 can be set to be twice the distance between the second transmission rod 222 and the support point in the extending direction of the first transmission rod 221, that is, L2 is equal to twice of L1, and the distance between the peak and valley of the mating surface is set to be 10 mm to ensure that the stroke of the second transmission rod 222 in the first direction e1 is 10 mm. In addition, when the second transmission rod 222 is in contact and cooperation with the middle position between the peak and valley, the air deflector louver 12 is parallel to the air outlet direction at the air outlet 210. Therefore, when the second transmission rod 222 moves from the middle position between the peak and valley towards the peak or valley, the air deflector louver 12 can be swung in two different directions.

[0075] According to some embodiments of the present invention, the mating surface includes a plurality of mating portions arranged in sequence along the extending direction of the mating track 2121, and the connection position of adjacent mating portions is located at the peak or valley of the mating surface. That is to say, in the first direction e1, the mating portion extends obliquely away from the second transmission rod 222 in the direction from the peak towards the valley, and the mating portion extends obliquely towards the second transmission rod 222 in the direction from the valley towards the peak. Therefore, the second transmission shaft moves between multiple peaks and multiple valleys by cooperating with multiple mating portions to adjust the position of the louver link 11 in the first direction e1. Thus, the moving speed and distance of the second transmission rod 222 in the first direction e1 can be controlled by the extending direction of the mating portion on the mating track 2121 and the inclination angle relative to the first direction e1.

[0076] According to some embodiments of the present invention, the included angle α between the mating portion and the reference plane satisfies: 5° ≤ α ≤ 60°, and the reference plane is perpendicular to the first direction e1. Wherein, when the mating portion is a plane, the included angle between the mating portion and the reference plane refers to the included angle between the plane where the mating portion is located and the reference plane; when the mating surface is a curved surface, the included angle between the mating portion and the reference plane refers to the included angle between the tangent plane at any point on the mating portion and the reference plane. That is, the included angle between the mating portion and the reference plane is controlled within the range of 5° to 60°. For example, the included angle between the mating portion and the reference plane can be 5°, or 8°, or 10°, or 14°, or 17°, or 20°, or 25°, or 30°, or 36°, or 42°, or 48°, or 55°, or 60°, etc., and no specific limitation is made here.

[0077] Among them, the larger the included angle between the mating portion and the reference plane, the steeper the slope of the mating portion relative to the reference plane, and the greater the resistance of the second transmission rod 222 moving along the mating portion from the trough to the adjacent crest. When the distance in the first direction e1 between the crest and the adjacent trough is determined, the shorter the path traveled by the second transmission rod 222 in the extending direction of the mating track 2121 when moving between the crest and the adjacent trough; conversely, the smaller the included angle between the mating portion and the reference plane, the gentler the slope of the mating portion relative to the reference plane, and the smaller the resistance of the second transmission rod 222 moving along the mating portion from the trough to the adjacent crest. When the distance in the first direction e1 between the crest and the adjacent trough is determined, the longer the path traveled by the second transmission rod 222 in the extending direction of the mating track 2121 when moving between the crest and the adjacent trough.

[0078] Therefore, by controlling the included angle between the mating portion and the reference plane within the range of 5° to 60°, it is possible to prevent the included angle between the mating portion and the reference plane from being too small, resulting in an excessive path length traveled by the second transmission rod 222 in the extending direction of the mating track 2121 when moving between the crest and the adjacent trough, increasing the output demand of the driving member 211. At the same time, it is possible to prevent the included angle between the mating portion and the reference plane from being too large, resulting in excessive resistance of the second transmission rod 222 when moving along the mating portion from the trough to the adjacent crest, which is beneficial to reducing the power consumption of the driving member 211 and ensuring the smooth movement of the second transmission rod 222 along the mating track 2121.

[0079] According to some embodiments of the present invention, there are two louver assemblies 1 and two lever transmission units 22 which are correspondingly connected and cooperated one by one. There are two mating tracks 2121. The two mating tracks 2121 include a first mating track 2121a and a second mating track 2121b which are respectively correspondingly mated with the two lever transmission units 22. The wall surface of the first mating track 2121a that contacts one end of the corresponding second transmission rod 222 is a first mating surface. The first mating surface includes multiple first mating portions arranged in sequence along the extending direction of the first mating track 2121a. The wall surface of the second mating track 2121b that contacts one end of the corresponding second transmission rod 222 is a second mating surface. The second mating surface includes multiple second mating portions arranged in sequence along the extending direction of the second mating track 2121b.

[0080] That is to say, the two lever transmission units 22 respectively realize the transmission connection with the first mating track 2121a and the second mating track 2121b through the contact and cooperation of their respective second transmission rods 222 with the first mating surface and the second mating surface. For the convenience of description, the lever transmission unit 22 that is in transmission cooperation with the first mating track 2121a is the first lever transmission unit 22a, the louver assembly 1 connected to the first lever transmission unit 22a is the first louver assembly 1a, the lever transmission unit 22 that is in transmission cooperation with the second mating track 2121b is the second lever transmission unit 22b, the louver assembly 1 connected to the second lever transmission unit 22b is the second louver assembly 1b. The third transmission rod 223 of the first lever transmission unit 22a is connected to the louver link 11 of the first louver assembly 1a, and the third transmission rod 223 of the second lever transmission unit 22b is connected to the louver link 11 of the second louver assembly 1b.

[0081] Therefore, when the driving member 211 drives the transmission seat 212 to move, the second transmission rod 222 of the first lever transmission unit 22a moves along the extension direction of the first fitting track 2121a relative to the first fitting track 2121a and moves in the first direction e1, and drives the louver link 11 of the first louver assembly 1a to move in the first direction e1 through the first transmission rod 221 and the third transmission rod 223 of the first lever transmission unit 22a, so as to adjust the deflection direction and angle of the air guiding louvers 12 of the first louver assembly 1a; the second transmission rod 222 of the second lever transmission unit 22b moves along the extension direction of the second fitting track 2121b relative to the second fitting track 2121b and moves in the first direction e1, and drives the louver link 11 of the second louver assembly 1b to move in the first direction e1 through the first transmission rod 221 and the third transmission rod 223 of the second lever transmission unit 22b, so as to adjust the deflection direction and angle of the air guiding louvers 12 of the second louver assembly 1b. In other words, when the driving member 211 drives the transmission seat 212 to move, the deflection direction and angle of the air guiding louvers 12 of the two louver assemblies 1 can be adjusted simultaneously, that is, the two louver assemblies 1 can share the same driving unit 21. Thus, the number of the driving units 21 can be saved preferably, and the installation space and input cost of the driving units 21 can be reduced.

[0082] Wherein, the multi-segment first fitting portion at least includes two portions parallel to the reference plane and having an included angle with the reference plane, the multi-segment second fitting portion at least includes two portions parallel to the reference plane and having an included angle with the reference plane or the second fitting surface extends in a wavy shape in the extension direction of the second fitting track 2121b, and the reference plane is perpendicular to the first direction e1.

[0083] That is to say, it can be that both the multiple segments of the first mating part and the multiple segments of the second mating part have portions with a parallel reference surface and portions with an included angle with the reference surface. During the movement of the transmission base 212, the second transmission rod 222 of the first lever transmission unit 22a can maintain its current position in the first direction e1 through the portion parallel to the reference surface of the first mating part, so as to keep the air guiding louver 12 of the first louver assembly 1a in the current position, and can adjust the deflection direction and angle of the air guiding louver 12 of the first louver assembly 1a through the portion of the first mating part with an included angle with the reference surface. The second transmission rod 222 of the second lever transmission unit 22b can maintain its current position in the first direction e1 through the portion parallel to the reference surface of the second mating part, so as to keep the air guiding louver 12 of the second louver assembly 1b in the current position, and can adjust the deflection direction and angle of the air guiding louver 12 of the second louver assembly 1b through the portion of the second mating part with an included angle with the reference surface. Thus, the deflection of the air guiding louver 12 of the first louver assembly 1a and the air guiding louver 12 of the second louver assembly 1b can be flexibly controlled to increase the diversity of the air outlet modes of the air conditioner 1000. For example, when the second transmission rod 222 of the first lever transmission unit 22a moves along the portion of the first mating surface parallel to the reference surface, the second transmission rod 222 of the second lever transmission unit 22b can move along the portion of the second mating surface with an included angle with the reference surface, so that the air guiding louver 12 of the first louver assembly 1a remains stationary and the air guiding louver 12 of the second louver assembly 1b rotates, etc., which will not be elaborated one by one here.

[0084] In addition, it can also be that the multiple segments of the first mating part have portions with a parallel reference surface and portions with an included angle with the reference surface, and the second mating surface extends in a wavy shape in the extending direction of the second mating track 2121b. Therefore, when the second transmission rod 222 of the second lever transmission unit 22b moves along the wavy second mating surface, the second transmission rod 222 of the first lever transmission unit 22a can move along the portion of the first mating part parallel to the reference surface to maintain the current position of the air guiding louver 12 of the first louver assembly 1a, and can also adjust the deflection direction and angle of the air guiding louver 12 of the first louver assembly 1a through the portion of the first mating part with an included angle with the reference surface to increase the diversity of the air outlet modes of the air conditioner 1000.

[0085] It should be noted that at the same time, the deflection directions of the air guiding louvers 12 of the first louver assembly 1a and the second louver assembly 1b can be the same or different to enhance the diversity of the air outlet modes of the air conditioner 1000. In a specific example, the first mating surface extends in a wavy shape in the extending direction of the first mating track 2121a, and the second mating surface extends in a wavy shape in the extending direction of the second mating track 2121b. Among them, when the second transmission rod 222 of the first lever transmission unit 22a is located at the peak position of the first mating surface, the second transmission rod 222 of the second lever transmission unit 22b can be located at the peak, or trough, or the middle position between the peak and the adjacent trough of the second mating surface; when the second transmission rod 222 of the first lever transmission unit 22a is located at the trough position of the first mating surface, the second transmission rod 222 of the second lever transmission unit 22b can be located at the peak, or trough, or the middle position between the peak and the adjacent trough of the second mating surface; when the second transmission rod 222 of the first lever transmission unit 22a is located at the middle position between the peak and the adjacent of the first mating surface, the second transmission rod 222 of the second lever transmission unit 22b can be located at the peak, or trough, or the middle position between the peak and the adjacent trough of the second mating surface, etc., which will not be elaborated one by one here.

[0086] According to some embodiments of the present invention, the mating track 2121 is a groove structure formed on the transmission seat 212. One end of the second transmission rod 222 contacts the bottom wall of the mating track 2121, and the bottom wall of the mating track 2121 constitutes the mating surface. That is to say, one end of the second transmission rod 222 extends into the mating track 2121, and the end face of the second transmission rod 222 extending into the mating track 2121 contacts the bottom wall of the mating track 2121, that is, the mating surface, so as to drive the second transmission rod 222 to move along the first direction e1 through the contact and cooperation between the second transmission rod 222 and the mating surface. Thus, through the mating track 2121 of the groove structure, while ensuring the transmission connection between the second transmission rod 222 and the mating track 2121, the opposite side walls of the mating track 2121, that is, the inner side walls on both sides of the groove in the direction perpendicular to the track extending direction, can better limit the freedom of movement of the second transmission rod 222 in the direction perpendicular to the track extending direction, so as to better prevent the second transmission rod 222 from disengaging from the mating track 2121, which is beneficial to improving the stability of the cooperation between the second transmission rod 222 and the transmission seat 212.

[0087] According to some embodiments of the present invention, the driving assembly 2 further includes an elastic member 23, and the elastic member 23 is used to push one end of the second transmission rod 222 located in the matching track 2121 to abut against the bottom wall of the matching track 2121. That is, the elastic member 23 can provide the second transmission rod 222 with a thrust to move toward the matching track 2121, so that the second transmission rod 222 always has a tendency to move toward the matching track 2121, which can better prevent the second transmission rod 222 from being out of engagement with the matching track 2121 and affecting the transmission matching relationship between the second transmission rod 222 and the transmission seat 212, and is conducive to improving the stability of the transmission matching between the lever transmission unit 22 and the driving unit 21.

[0088] According to some embodiments of the present invention, the driving assembly 2 further includes: a housing 24, the second transmission rod 222 and the transmission seat 212 are both arranged in the housing 24, a limiting groove 2411 opposite to the matching track 2121 is arranged on the inner wall surface of the housing 24, and the other end of the second transmission rod 222 is located in the limiting groove 2411 and is movable relative to the limiting groove 2411. Thus, the movement direction of the second transmission rod 222 can be better limited by the limiting groove 2411, that is, the second transmission rod 222 can only move along the extension direction of the limiting groove 2411, which is conducive to improving the reliability of the lever transmission unit 22. Further, the elastic member 23 is arranged in the limiting groove 2411 and is connected to or abuts against the second transmission rod 222. Among them, the elastic member 23 can be arranged between the bottom wall of the limiting groove 2411 and the other end of the second transmission rod 222, that is, the end face of the second transmission rod 222 away from the matching track 2121, and one end of the elastic member 23 abuts against the bottom wall of the limiting groove 2411 and the other end abuts against the other end face of the second transmission rod 222; or one end of the elastic member 23 can be fixedly arranged in the limiting groove 2411, and the other end of the elastic member 23 is fixedly connected to the second transmission rod 222 to ensure that the elastic member 23 can provide the second transmission rod 222 with a thrust to move toward the direction close to the transmission rod 212. No specific restriction is made on the setting method of the elastic member 23 here.

[0089] In a specific example, the limiting groove 2411 and the second transmission rod 222 both extend along the first direction e1, one end of the second transmission rod 222 abuts against the bottom wall of the mating track 2121, and the other end of the second transmission rod 222 extends into the limiting groove 2411, and the first transmission rod 221 is rotatably arranged at the center position of the second transmission rod 222 in the first direction e1, thereby preventing the risk of interference with the shell 24 during the rotation of the first transmission rod 221.

[0090] According to some embodiments of the present invention, a plurality of louver assemblies 1 are provided, and a plurality of lever transmission units 22 are provided, which are in one-to-one correspondence with the plurality of louver assemblies 1. A plurality of mating tracks 2121 are formed on the transmission seat 212, and the number of the plurality of mating tracks 2121 is the same as that of the plurality of lever transmission units 22 and they are in one-to-one correspondence. That is to say, the bottom wall of each mating track 2121 is in contact and cooperation with one end of the second transmission rod 222 of the corresponding lever transmission unit 22, and is connected to the louver link 11 of the corresponding louver assembly 1 through the third transmission rod 223 of each lever transmission unit 22, so that each mating track 2121 can adjust the deflection direction and angle of the air guiding louver 12 of the corresponding louver assembly 1 through the corresponding lever transmission unit 22. That is, when the transmission seat 212 moves, it can simultaneously adjust the deflection direction and angle of the air guiding louvers 12 of the plurality of louver assemblies 1. Thus, the plurality of louver assemblies 1 share the same driving unit 21, which can preferably save the number of driving units 21, thereby reducing the installation space and input cost of the driving unit 21.

[0091] According to some embodiments of the present invention, the drive shaft of the driving member 211 is connected to the transmission seat 212 to drive the transmission seat 212 to rotate around the first direction e1, and the mating track 2121 is located on the outer peripheral side of the drive shaft and extends along the rotation direction of the transmission seat 212. That is to say, the rotation of the drive shaft of the driving member 211 drives the transmission seat 212 to rotate, driving the mating track 2121 to move relative to the second transmission rod 222, so that the mating position of the second transmission rod 222 and the mating track 2121 can be adjusted to change the position of the second transmission rod 222 in the first direction e1. Thus, the transmission seat 212 only needs to rotate to drive the second transmission rod 222 to move, and the transmission seat 212 does not occupy additional moving space during the rotation process, so that the installation space of the transmission seat 212 can be preferably saved, and the structure of the driving assembly 2 is compact. Among them, the driving member 211 can be a driving motor with a small size. In a specific example, the mating track 2121 is annular, so that the second transmission rod 222 can move in the mating track 2121 along one direction, which is beneficial to reducing the difficulty of driving the transmission seat 212 to move by the driving member 211. In addition, when a plurality of mating tracks 2121 are provided, such as having a first mating track 2121a and a second mating track 2121b, the first mating track 2121a is located on the inner peripheral side of the second mating track 2121b, that is, the plurality of mating tracks 2121 are arranged in a nested manner in sequence.

[0092] According to some embodiments of the present invention, the driving member 211 and the transmission seat 212 are arranged along the first direction e1. In the first direction e1, the driving member 211 is located on the side of the transmission seat 212 away from the lever transmission unit 22, and a matching track 2121 is formed on the end surface of the transmission seat 212 away from the driving member 211. In other words, the lever transmission unit 22 and the driving member 211 are respectively located on opposite sides of the transmission seat 212 in the first direction e1. As a result, the lever transmission unit 22, the transmission seat 212 and the driving member 211 can make full use of the installation space in the first direction e1, and the lever transmission unit 22 can be better separated from the driving member 211 to avoid the risk of interference between the lever transmission unit 22 and the driving member 211 during movement, which is conducive to improving the stability of the driving assembly 2.

[0093] According to some embodiments of the present invention, the drive unit 21 and the louver assembly 1 are located on opposite sides of the lever transmission unit 22 in the first direction e1. That is, the louver assembly 1 is located on one side of the lever transmission unit 22 in the first direction e1, and the drive unit 21 is located on the other side of the lever transmission unit 22 away from the louver assembly 1 in the first direction e1. As a result, the louver assembly 1, the lever transmission unit 22 and the drive unit 21 can make full use of the installation space in the first direction e1, so that the size of the air guide mechanism 100 in the direction perpendicular to the first direction e1 can be better controlled, and at the same time, the drive unit 21 and the louver assembly 1 can be prevented from interfering with each other on the same side of the lever transmission unit 22 in the first direction e1, such as preventing the drive unit 21 from blocking the air outlet at the air guide louver 12 or affecting the normal rotation of the air guide louver 12, which is beneficial to improving the stability of the air guide mechanism 100.

[0094] According to some embodiments of the present invention, the driving assembly 2 further includes: a housing 24, a first installation cavity 245 and a second installation cavity 246 are formed in the housing 24 and arranged along a first direction e1. The lever transmission unit 22 is disposed in the first installation cavity 245, and the driving unit 21 is disposed in the second installation cavity 246. A through communication hole 2421 is formed between the first installation cavity 245 and the second installation cavity 246. The second transmission rod 222 passes through the communication hole 2421. A guiding hole 2412 penetrating the housing 24 is formed on the side wall of the first installation cavity 245. The third transmission rod 223 is connected to the louver link 11 through the guiding hole 2412. That is to say, the second transmission rod 222 is in transmission connection with the driving unit 21 located in the second installation cavity 246 through the communication hole 2421. At the same time, the communication hole 2421 can preferably limit the movement direction of the second transmission rod 222, so that the second transmission rod 222 can only move along the extension direction of the communication hole 2421. While the guiding hole 2412 facilitates the connection between the third transmission rod 223 and the louver link 11 located outside the housing 24, the guiding hole 2412 can preferably limit the movement direction of the third transmission rod 223, that is, the third transmission rod 223 can only move along the extension direction of the guiding hole 2412. Thus, the transmission stability of the lever transmission unit 22 can be preferably improved. Moreover, by separately placing the lever transmission unit 22 and the driving unit 21 in the first installation cavity 245 and the second installation cavity 246 respectively, it is convenient to independently maintain the lever transmission unit 22 and the driving unit 21 in the later stage, thereby reducing the maintenance difficulty. In a specific example, the third transmission rod 223 is detachably connected to the louver link 11. Therefore, the assembly difficulty between the driving assembly 2 and the louver assembly 1 can be preferably reduced.

[0095] Among them, a support rod 2413 is provided in the first installation cavity 245, and the first transmission rod 221 is rotatably provided on the support rod 2413 around a support point. In a specific example, a rotating shaft 224 is provided on the support rod 2413 and is penetrated through the first transmission rod 221 and is rotatable relative to the first transmission rod 221, so as to ensure that the first transmission rod 221 can rotate relative to the rotating shaft 224, and the rotating shaft 224 constitutes a support point. In addition, the second installation cavity 246 includes a first sub-installation cavity 2461 and a second sub-installation cavity 2462, the transmission seat 212 is provided in the first sub-installation cavity 2461, and the driving member 211 is provided in the second sub-installation cavity 2462. In the first direction e1, the first sub-installation cavity 2461 is located between the second sub-installation cavity 2462 and the first installation cavity 245, and the driving shaft of the driving member 211 extends into the first sub-installation cavity 2461 and is connected to the transmission seat 212, so as to drive the transmission seat 212 to rotate through the rotation of the driving shaft. Specifically, the housing 24 includes a guide seat 241, a turntable seat 242, a turntable cover 243 and a motor cover 244 which are sequentially connected along the first direction e1. The guide seat 241 and the turntable seat 242 jointly define a first installation cavity 245. The turntable seat 242 and the turntable cover 243 jointly define a first sub-installation cavity 2461. The turntable cover 243 and the motor cover 244 jointly define a second sub-installation cavity 2462. A support rod 2413 is provided on the side of the guide seat 241 facing the turntable seat 242. A guide hole 2412 is formed which passes through along the first direction e1, a connecting hole 2421 which passes through along the first direction e1 is formed on the turntable seat 242, and a limiting ring is provided on the side of the turntable seat 242 facing the turntable cover 243, a limiting protrusion which cooperates with the limiting ring is formed on the end face of the transmission seat 212 which is away from the driving member 211, the limiting protrusion is located in the limiting ring and is rotatable relative to the limiting ring, a through hole which passes through along the first direction e1 is formed on the turntable cover 243, and the driving shaft of the driving member 211 is penetrated in the through hole.

[0096] According to some embodiments of the present invention, multiple shutter assemblies 1 are provided, and multiple lever transmission units 22 are provided corresponding to the shutter assemblies 1 one by one, and the shutter connecting rods 11 of the multiple shutter assemblies 1 are all connected to the driving unit 21 through the corresponding lever transmission units 22. In other words, the driving unit 21 can drive the shutter connecting rods 11 of the multiple shutter assemblies 1 to move along the first direction e1 through the multiple lever transmission units 22, thereby adjusting the deflection direction and angle of the wind guide shutters 12 of the multiple shutter assemblies 1, that is, the multiple shutter assemblies 1 share the same driving unit 21. As a result, the number of driving units 21 can be saved, thereby reducing the installation space and investment cost of the driving unit 21.

[0097] According to some embodiments of the present invention, the air guiding mechanism 100 further includes: an air guiding plate 3, the air guiding plate 3 has an air guiding surface 311, and the air guiding louvers 12 are swingably arranged on the air guiding surface 311. Thus, by arranging the air guiding louvers 12 on the air guiding surface 311, the air guiding louvers 12 can make full use of the installation space on the air guiding plate 3, and at the same time, it can better avoid the air guiding louvers 12 from blocking the air flow in the air outlet 210. Therefore, the air outlet loss can be better reduced. At the same time, during the assembly process of the air guiding mechanism 100, the air guiding louvers 12 and the air guiding plate 3 can be assembled first, and then the air guiding mechanism 100 can be installed on an air conditioning device such as an air conditioner 1000, which is beneficial to reducing the assembly difficulty of the louver assembly 1.

[0098] According to some embodiments of the present invention, there are two louver assemblies 1 and two lever transmission units 22. The two louver assemblies 1 are respectively a first louver assembly 1a and a second louver assembly 1b. The first louver assembly 1a includes a first air guiding louver 12a and a first louver connecting rod 11a. The second louver assembly 1b includes a second air guiding louver 12b and a second louver connecting rod 11b. The two lever transmission units 22 are respectively a first lever transmission unit 22a that is drivably connected between the driving unit 21 and the first louver connecting rod 11a and a second lever transmission unit 22b that is drivably connected between the driving unit 21 and the second louver connecting rod 11b. The first louver connecting rod 11a includes a main body portion 11a1 and a connecting portion 11a2 that both extend along a first direction e1. The first air guiding louver 12a is rotatably connected to the main body portion 11a1. In the first direction e1, the main body portion 11a1 is located on the side of the second louver connecting rod 11b away from the driving assembly 2. The main body portion 11a1 is connected to the third transmission rod 223 of the first lever transmission unit 22a through the connecting portion 11a2, and the second louver connecting rod 11b is connected to the third transmission rod 223 of the second lever transmission unit 22b.

[0099] That is to say, the driving unit 21 can simultaneously drive the connecting portion 11a2 and the second louver connecting rod 11b to move along a second direction through the first lever transmission unit 22a and the second lever transmission unit 22b respectively. When the connecting portion 11a2 moves along the first direction e1, it drives the main body portion 11a1 to move along the first direction e1, and then drives the first air guiding louver 12a to swing relative to the air guiding plate 3 to adjust the deflection direction and angle of the first air guiding louver 12a. When the second louver connecting rod 11b moves along the first direction e1, it drives the second air guiding louver 12b to swing relative to the air guiding plate 3 to adjust the deflection direction and angle of the second air guiding louver 12b. Thus, the first louver assembly 1a and the second louver assembly 1b share one driving unit 21, which can better save the number of driving units 21, thereby reducing the installation space and input cost of the driving units 21.

[0100] According to some embodiments of the present invention, a guiding groove 34 extending along the first direction e1 is formed on the air deflector 3, and at least a part of the connecting portion 11a2 is movably received in the guiding groove 34 along the first direction e1. Thus, the movement direction of the connecting portion 11a2 can be well restricted by the guiding groove 34, that is, the connecting portion 11a2 can only move along the extending direction of the guiding groove 34, i.e., the first direction e1. At the same time, the connecting portion 11a2 can be limited from both sides in the width direction by the guiding groove 34, which can well prevent the risk of bending of the connecting portion 11a2 during movement due to its excessive length, and is beneficial to improving the transmission stability between the third transmission rod 223 and the main body portion 11a1. Herein, it can be that a part of the connecting portion 11a2 is movably received in the guiding groove 34 along the first direction e1, or the connecting portion 11a2 can be completely received in the guiding groove 34 when moving along the first direction e1, and no specific limitation is made here.

[0101] According to some embodiments of the present invention, a receiving cavity 33 is formed in the air deflector 3, and at least a part of the connecting portion 11a2 is movably received in the receiving cavity 33 along the first direction e1. Thus, the air deflector 3 can well block the part of the connecting portion 11a2 located in the receiving cavity 33, that is, a part of the first louver link 11a is hidden and installed inside the air deflector 3. Thus, the connecting portion 11a2 can make full use of the space inside the air deflector 3, and at the same time, it can avoid the connecting portion 11a2 being arranged on the air guiding surface 311 to block the air flow, so as to reduce the air volume loss and is beneficial to improving the appearance neatness of the air guiding mechanism 100. Herein, it can be that a part of the connecting portion 11a2 is located in the receiving cavity 33, or the connecting portion 11a2 can be completely located in the receiving cavity 33, and no specific limitation is made here.

[0102] According to some embodiments of the present invention, the air deflector 3 includes an inner air deflector 31 and an outer air deflector 32 arranged along the thickness direction of the air deflector 3. The side surface of the inner air deflector 31 facing away from the outer air deflector 32 constitutes the air guiding surface 311. The inner air deflector 31 and the outer air deflector 32 jointly define a receiving cavity 33. A guiding groove 34 extending along the first direction e1 is provided on one of the side surfaces of the inner air deflector 31 facing the receiving cavity 33 and the side surface of the outer air deflector 32 facing the receiving cavity 33. At least a part of the connecting portion 11a2 is movably received in the guiding groove 34 along the first direction e1. That is to say, the movement direction of the connecting portion 11a2 can be well restricted by the guiding groove 34. That is, the connecting portion 11a2 can only move along the extending direction of the guiding groove 34, that is, the first direction e1. At the same time, the connecting portion 11a2 can be limited from both sides in the width direction by the guiding groove 34, which can better prevent the risk of the connecting portion 11a2 being bent during the movement due to its too long length. In addition, the inner air deflector 31 and the outer air deflector 32 can better block the part of the connecting portion 11a2 located in the guiding groove 34. Therefore, it is beneficial to improve the transmission stability of the connecting portion 11a2 between the third transmission rod 223 and the main body portion 11a1. At the same time, the connecting portion 11a2 can make full use of the space inside the air deflector 3, and at the same time, the connecting portion 11a2 can be prevented from being arranged on the air guiding surface 311 to block the air flow, so as to reduce the air volume loss and improve the appearance neatness of the air guiding mechanism 100. Among them, it can be that a part of the connecting portion 11a2 is movably received in the guiding groove 34 along the first direction e1, or the connecting portion 11a2 can be completely received in the guiding groove 34 when moving along the first direction e1, and no specific limitation is made here. Secondly, a receiving cavity 33 is formed between the inner air deflector 31 and the outer air deflector 32. Through the receiving cavity 33, the heat transfer between the inner air deflector 31 and the outer air deflector 32 can be better reduced, so as to prevent the formation of condensation on the outer side surface of the outer air deflector 32 and affect the use experience.

[0103] According to some embodiments of the present invention, the driving assembly 2 is arranged on the air deflector 3. That is to say, both the louver assembly 1 and the driving assembly 2 are arranged on the air deflector 3. Therefore, the difficulty of the transmission connection between the louver assembly 1 and the driving assembly 2 can be better reduced, which is beneficial to improving the assembly effect of the air guiding mechanism 100. In a specific example, the driving assembly 2 is arranged on the air guiding surface 311 of the air deflector 3. When the air deflector 3 closes the air outlet 210, the air guiding surface 311 faces the inside of the air outlet 210, so that the driving assembly 2 can be better hidden to improve the appearance neatness when the air conditioner 1000 is closed.

[0104] The air conditioner 1000 according to the second aspect embodiment of the present invention will be described below with reference to the accompanying drawings.

[0105] As Figures 11 - 15As shown, the air conditioner 1000 according to the embodiment of the second aspect of the present invention includes: a wind guiding mechanism 100.

[0106] For the air conditioner 1000 according to the embodiment of the second aspect of the present invention, by setting the distance between the second transmission rod 222 and the support point to be less than the distance between the third transmission rod 223 and the support point, the stroke of the second transmission rod 222 can be better shortened, thereby the movement range of the second transmission rod 222 can be reduced, and further the avoidance space reserved for the movement of the second transmission rod 222 by the wind guiding mechanism 100 can be reduced, with reasonable layout and compact structure.

[0107] Among them, the air conditioner 1000 includes a front panel, and an air outlet 210 is formed on the front panel. The wind guiding mechanism 100 is movably arranged on the front panel to move between a position where the air outlet 210 is opened and a position where the air outlet 210 is closed. In a specific example, the air conditioner 1000 is a wall-mounted type.

[0108] In a specific example, the louver assembly 1 has two louver assemblies which are the first louver assembly 1a and the second louver assembly 1b respectively. The guiding louvers 12 of the first louver assembly 1a are located on one side of the guiding louvers 12 of the second louver assembly 1b in the first direction e1. The air conditioner 1000 has at least one of a first mode, a second mode, and a third mode. Specifically, in the first mode, the guiding louvers 12 of the first louver assembly 1a, that is, the first guiding louvers 12a, and the guiding louvers 12 of the second louver assembly 1b, that is, the second guiding louvers 12b, are inclined in the air outlet direction towards directions away from each other, that is, the first guiding louvers 12a and the second guiding louvers 12b guide air in the air outlet direction towards directions away from each other, thereby realizing surround-type air supply; in the second mode, the first guiding louvers 12a and the second guiding louvers 12b are inclined and extended in the air outlet direction towards directions close to each other, that is, the first guiding louvers 12a and the second guiding louvers 12b guide air in the air outlet direction towards directions close to each other, thereby realizing a wind gathering effect to increase the air supply distance; in the third mode, the first guiding louvers 12a and the second guiding louvers 12b are parallel and have an included angle with the air outlet direction at the air outlet 210, that is, the first guiding louvers 12a and the second guiding louvers 12b can guide air in the same direction, thereby realizing lateral large-angle wide-angle air sweeping.

[0109] Specifically, if the first direction e1 is the left-right direction, the first air guide louver 12a is located on the left side of the second air guide louver 12b. In the first mode, the first air guide louver 12a deflects toward the left in the air outlet direction from back to front, and the second air guide louver 12b deflects toward the right in the air outlet direction from back to front. Therefore, the first louver assembly 1a can guide air toward the left, and the second louver assembly 1b can guide air toward the right, thereby realizing left-right surrounding air supply; in the second mode, the first air guide louver 12a deflects toward the right in the air outlet direction from back to front, and the second air guide louver 12b deflects toward the left in the air outlet direction from back to front. Therefore, the first louver assembly 1a can guide air toward the right, and the second louver assembly 1b can guide air toward the left, so that the air flow guided by the first louver assembly 1a converges with the air flow guided by the second louver assembly 1b between the first louver assembly 1a and the second louver assembly 1b to increase the air supply distance after the air outlet passes through the air guide mechanism 100; in the third mode, both the first air guide louver 12a and the second air guide louver 12b deflect toward the left or both deflect toward the right in the air outlet direction from back to front, thereby realizing large-angle wide-angle air sweeping of the air guide mechanism 100 toward the left or large-angle wide-angle air sweeping toward the right.
