[0065] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0066] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0067] Combine Figure 1-33 As shown, an embodiment of the present disclosure provides a driving device for an air guide plate 100 of an air conditioner.

[0068] The air conditioner includes an indoor unit and an outdoor unit connected by a connecting pipe. The indoor unit includes a housing 10, an evaporator, a fan, and an air deflector 100. The housing 10 defines an air duct, within which the evaporator and fan are located. The housing 10 is provided with an air inlet and an air outlet connected to the air duct, and the air deflector 100 is located at the air outlet. The fan drives air into the air duct through the air inlet, where it exchanges heat with the evaporator before being blown out of the air outlet. The air deflector 100 is used to adjust the airflow direction of the air outlet. Specifically, the airflow direction of the air outlet varies depending on the air deflector 100's position.

[0069] like Figure 13 As shown, the driving device for the air-conditioning air guide plate 100 includes a gear 1 , a first connecting rod 2 , a turntable 3 , a second connecting rod 4 and a driving member 8 .

[0070] The gear 1 rotates in a controlled manner; the first connecting rod 2 is provided with gear teeth in the form of a rack, the gear teeth of the first connecting rod 2 are engaged with the gear 1, and the first connecting rod 2 is movably connected to the air guide plate 100; the turntable 3 rotates in a controlled manner; the second connecting rod 4 is drive-connected to the turntable 3 and is movably connected to the air guide plate 100; the rotation of the gear 1 drives the first connecting rod 2 to move, and the rotation of the turntable 3 drives the second connecting rod 4 to move, so as to jointly drive the air guide plate 100 to open and close.

[0071] Gear 1 is engaged with the first connecting rod 2. The rotation of gear 1 drives the first connecting rod 2 to move. The first connecting rod 2 is connected to the air deflector 100. Under the rotation of gear 1, the first connecting rod 2 can drive the air deflector 100 to move, thereby realizing the closing and opening of the air deflector 100.

[0072] The turntable 3 can drive the second connecting rod 4 to move. When the turntable 3 rotates, the second connecting rod 4 can drive the air guide plate 100 to move, thereby closing and opening the air guide plate 100.

[0073] The turntable 3 cooperates with the second link 4 to drive the second link 4 to move. The turntable 3 and the second link 4 can adopt a movable connection (such as a sliding connection, a rotating connection), a fixed connection, etc. to drive the second link 4 to move. The gear 1 is engaged with the first link 2 to drive the first link 2 to move. The second link 4 and the first link 2 cooperate together to drive the air guide plate 100 to move.

[0074] In this application, gear 1 and turntable 3 are used to jointly drive the air guide plate 100 to move. Compared with the related art that only uses turntable 3 for driving, the force acting on turntable 3 can be reduced and the life of turntable 3 can be improved; compared with the related art that only uses gear 1 group for driving, the complexity of gear 1 group can be reduced.

[0075] The driving member 8 is drivingly connected to the gear 1 and the turntable 3 to drive the gear 1 and the turntable 3 to rotate.

[0076] Alternatively, as Figure 14 and Figure 15 As shown, the rotational angular velocities of gear 1 and turntable 3 are equal.

[0077] The gear 1 and the turntable 3 can be of an integrated structure or a split structure. When the rotational angular velocities of the gear 1 and the turntable 3 are equal, the gear 1 and the turntable 3 can be driven by the same driving member 8 (e.g., a motor), which can reduce the number of driving members 8 and simplify the control logic of the first connecting rod 2 and the turntable 3, thereby reducing costs, optimizing space utilization, and making the structure more compact.

[0078] The gear 1 and the turntable 3 have the same rotational angular velocity, which facilitates the design of the speed difference between the second connecting rod 4 and the first connecting rod 2 to drive the air guide plate 100 to move to various target positions, thereby meeting different user requirements.

[0079] Optionally, the gear 1 is provided on one side of the turntable 3 and coincides with the rotation axis of the turntable 3 .

[0080] On the one hand, the spatial arrangement of the gear 1 and the turntable 3 is made more compact and the space usage is more optimized. On the other hand, the gear 1 and the turntable 3 can rotate simultaneously under the drive of the same driving member 8 and have the same rotational angular velocity.

[0081] Optionally, the driving device for the air-conditioning air guide plate 100 further includes a driving member 8 , and the number of the driving member 8 is one. The driving member 8 is drivingly connected to both the gear 1 and the turntable 3 to drive the gear 1 and the turntable 3 to rotate.

[0082] There is one driving member 8, which is driven by both the gear 1 and the turntable 3, so that the driving member 8 can drive the gear 1 and the turntable 3 to rotate at the same time, so that the gear 1 and the turntable 3 can rotate synchronously when rotating to avoid conflict and interference.

[0083] When the number of driving members 8 is reduced, the control logic of the first connecting rod 2 and the turntable 3 can be simplified, and later maintenance and repair are also facilitated.

[0084] Optionally, the driving device for the air-conditioning air guide plate 100 further includes a transmission shaft, and the driving member 8 is drivingly connected to the transmission shaft.

[0085] When the driving member 8 is disposed on the side of the gear 1 facing away from the turntable 3, the transmission shaft passes through the gear 1 and is connected to the turntable 3. Thus, when the driving member 8 drives the transmission shaft to rotate, the transmission shaft can drive both the gear 1 and the turntable 3, thereby achieving controlled rotation of the gear 1 and the turntable 3. The connection between the transmission shaft and the turntable 3 is a fixed connection, such as a clip-on connection or a screw connection.

[0086] When the driving member 8 is disposed on the side of the turntable 3 facing away from the gear 1, the transmission shaft passes through the turntable 3 and is connected to the gear 1. Thus, when the driving member 8 drives the transmission shaft to rotate, the transmission shaft can drive both the gear 1 and the turntable 3 to rotate, achieving controlled rotation of the gear 1 and the turntable 3. The connection between the transmission shaft and the gear 1 is a fixed connection, such as a clip-on connection or a screw connection.

[0087] Alternatively, as Figure 14 As shown, the gear 1 includes a middle portion 14 , an edge portion 13 and a reinforcement rib 12 .

[0088] The middle portion 14 is matched with the transmission shaft; the edge portion 13 is arranged on the outside of the middle portion 14, and a hollow portion 11 is provided between the middle portion 14 and the edge portion 13; the reinforcing rib 12 is provided in the hollow portion 11 and connected between the middle portion 14 and the edge portion 13. The outer side of the edge portion 13 is provided with gear teeth, which mesh with the rack, for example Figure 16 As shown, it is external engagement.

[0089] When the driving member 8 is arranged on the side of the gear 1 away from the turntable 3, the middle part 14 is provided with a mounting hole 141, and the transmission shaft passes through the mounting hole 141 and is connected to the turntable 3; when the driving member 8 is arranged on the side of the turntable 3 away from the gear 1, the transmission shaft passes through the turntable 3 and is connected to the middle part 14.

[0090] Providing the hollow portion 11 can reduce the material usage of the gear 1 and reduce the cost of the gear 1. Providing the reinforcing rib 12 can enhance the strength of the gear 1, thereby ensuring the strength of the gear 1 while reducing the material usage of the gear 1 and improving the safety and durability of the gear 1.

[0091] There are multiple reinforcing ribs 12 , each of which extends along the radial direction of the gear 1 , and the multiple reinforcing ribs 12 are distributed radially.

[0092] Optionally, the gear 1 and the turntable 3 are an integrated structure.

[0093] The one-piece structure can reduce the processing and production steps of parts, thereby improving production efficiency and reducing molding costs. The use of one-piece molding can also improve the strength of the gear 1 and the turntable 3, enhance the safety and durability of the use of the gear 1 and the turntable 3, and extend the service life of the structure.

[0094] The integrated structure of the gear 1 and the turntable 3 can simplify the installation process of the driving device for the air-conditioning air guide plate 100 and also facilitate subsequent maintenance and repair.

[0095] Alternatively, as Figure 14 As shown, the radial dimension of the rotating disk 3 is larger than the radial dimension of the gear 1 .

[0096] In this way, the surface of the first connecting rod 2 facing the turntable 3 can contact the turntable 3, and the turntable 3 can limit the first connecting rod 2, preventing the first connecting rod 2 from moving along the axis of the rotating shaft of the gear 1 (that is, the axis of the transmission shaft) in the direction from the gear 1 to the turntable 3.

[0097] Alternatively, as Figure 34 As shown, a groove 242 is provided on the surface of the first connecting rod 2 facing the rotating disk 3 .

[0098] This arrangement reduces the contact area between the surface of the first connecting rod 2 facing the turntable 3 and the turntable 3, thereby reducing the friction between the surface of the first connecting rod 2 and the turntable 3, reducing the wear of the first connecting rod 2 and the turntable 3 during movement, extending the service life of the first connecting rod 2 and the turntable 3, and reducing friction while also reducing noise.

[0099] There are one or more grooves, and the grooves extend along the length direction of the first connecting rod 2 .

[0100] Alternatively, as Figure 8 and Figure 15 As shown, one of the turntable 3 and the second connecting rod 4 is provided with a driving column, and the other is provided with a driving groove. The driving column is located in the driving groove and can slide relative to the driving groove, so that the turntable 3 drives the second connecting rod 4 to move.

[0101] The rotating disk 3 may be provided with a driving post, and the second connecting rod 4 may be provided with a driving groove. The rotating disk 3 may also be provided with a driving groove, and the second connecting rod 4 may be provided with a driving post.

[0102] The driving column is adapted to the driving groove, and the driving column slides relative to the driving groove in the driving groove, so that the action force between the driving column and the driving groove drives the second connecting rod 4 to move, thereby realizing the driving of the second connecting rod 4 by the turntable 3.

[0103] By setting the shape, length and other parameters of the driving groove and combining the setting position of the driving column, the force between the driving column and the driving groove can be changed, thereby changing the movement speed of the second connecting rod 4, including the speed magnitude and / or movement direction of the second connecting rod 4.

[0104] There are multiple driving slots, and the number of driving posts is equal to and corresponds to the number of driving slots. Figure 8 and Figure 15 As shown, there are two driving slots and two driving posts.

[0105] The plurality of drive grooves include a first drive groove 41 and a second drive groove 42. The plurality of drive posts include a first drive post 31 located in the first drive groove 41 and capable of sliding relative to the first drive groove 41, and a second drive post 32 located in the second drive groove 42 and capable of sliding relative to the second drive groove 42. The first drive groove 41 and the second drive groove 42 are arranged crosswise, and the first drive groove 41 and the second drive groove 42 have different depths. Accordingly, the first drive post 31 and the second drive post 32 have different heights. Thus, the first drive groove 41 is adapted to fit the first drive post 31 but not the second drive post 32, and the second drive groove 42 is adapted to fit the second drive post 32 but not the first drive post 31. Therefore, when the first drive column 31 slides in the first drive groove 41 to the intersection of the first drive groove 41 and the second drive groove 42, there is no interaction force or the interaction force is very small between the first drive column 31 and the second drive groove 42. When the second drive column 32 slides in the second drive groove 42 to the intersection of the first drive groove 41 and the second drive groove 42, there is no interaction force or the interaction force is very small between the second drive column 32 and the first drive groove 41, thereby avoiding the interaction between the first drive column 31 and the second drive groove 42, and the interaction between the second drive column 32 and the first drive groove 41, which affects the movement trajectory of the air guide plate 100.

[0106] The first driving groove 41 and the second driving groove 42 are both curved grooves.

[0107] The first drive groove 41 includes a first sub-drive groove 411 and a second sub-drive groove 412. The extension line of the first sub-drive groove 411 and the extension line of the second sub-drive groove 412 intersect, and the first sub-drive groove 411 and the second sub-drive groove 412 are arranged in sequence along the length direction of the second connecting rod 4. The first sub-drive groove 411 and the second sub-drive groove 412 are connected, and the connection point forms a first angle 413. The first sub-drive groove 411 and the second sub-drive groove 412 are both curved grooves.

[0108] The second driving groove 42 includes a third sub-driving groove 421 .

[0109] like Figure 4 As shown, when the air guide plate 100 is in the closed position, the first driving column 31 is located on the end of the first sub-driving groove 411 away from the first folded corner 413; Figure 11 As shown, as the air guide plate 100 opens to the fourth position, the first drive column 31 cooperates with the first sub-drive groove 411, the first corner 413 and the second sub-drive groove 412 in sequence, and the second drive column 32 cooperates with the third sub-drive groove 421.

[0110] The first drive slot 41 further includes a fourth sub-drive slot 414, which is connected to the second sub-drive slot 412 and extends substantially along the length direction of the second connecting rod 4. The fourth sub-drive slot 414 intersects with the third sub-drive slot 421. The fourth sub-drive slot 414 is a curved slot. The second drive slot 42 further includes a fifth sub-drive slot 422, which is connected to the third sub-drive slot 421. Both sub-drive slots are arranged sequentially substantially along the length direction of the second connecting rod 4, and both sub-drive slots extend substantially along the length direction of the second connecting rod 4. Figure 20 As shown, when the air guide plate 100 continues to open from the fourth position to the second position, the first driving column 31 cooperates with the fourth sub-driving groove 414 , and the second driving column 32 cooperates with the fifth sub-driving groove 422 .

[0111] The first drive slot 41 further includes a sixth sub-drive slot 415, which is connected to the fourth sub-drive slot 414 and forms a second angle 416 at the connection point. The second angle 416 is an obtuse angle. The second drive slot 42 further includes a seventh sub-drive slot 423, which extends substantially along the width direction of the second connecting rod 4. The seventh sub-drive slot 423 is connected to the fifth sub-drive slot 422 and forms a third angle 424 at the connection point. The third angle 424 is substantially 90 degrees. Figure 25 As shown, when the air guide plate 100 continues to open from the second position to the fifth position, the second drive column 32 is located in the seventh sub-drive groove 423 and moves along the seventh sub-drive groove 423 in the direction away from the fifth sub-drive groove 422, and the first drive column 31 is located in the sixth sub-drive groove 415 and moves along the sixth sub-drive groove 415 in the direction away from the fourth sub-drive groove 414. In the fifth position, the second drive column 32 is located at one end of the seventh sub-drive groove 423 away from the fifth sub-drive groove 422.

[0112] like Figure 23 and Figure 28 As shown, the air guide plate 100 continues to open from the fifth position toward the third position, the second drive column 32 remains on the seventh sub-drive groove 423 at one end away from the fifth sub-drive groove 422, and the first drive column 31 continues to move in the sixth sub-drive groove 415 in the direction away from the fourth sub-drive groove 414. When reaching the third position, the first drive column 31 moves to the end of the sixth sub-drive groove 415 away from the fifth sub-drive groove 422.

[0113] The air guide plate 100 passes through the first position, the fourth position, the second position, the fifth position, and the third position in sequence during its opening process. The first position is the closed position, the fourth position is one of the horizontal blowing position for cooling and the downward blowing position for heating, the second position is the first maximum air supply position, the fifth position is the other of the horizontal blowing position for cooling and the downward blowing position for heating, and the third position is the second maximum air supply position.

[0114] At the first maximum air supply position and the second maximum air supply position, under the same conditions (for example, the power of the compressor and the power of the fan are the same), the air output at the first maximum air supply position and the second maximum air supply position is the maximum.

[0115] In some embodiments, the air guide plate 100 reaches the second maximum air supply position when it is flipped at a certain angle (eg, 180°) from the first maximum air supply position.

[0116] The first connecting rod 2 is rotatably connected to the air deflector 100 via a first rotating shaft 51 ; the second connecting rod 4 is rotatably connected to the air deflector 100 via a second rotating shaft 52 .

[0117] like Figure 31 As shown, when the air guide plate 100 is in the closed position, two points A1 and B1 are selected on the air guide plate 100. At this time, the position of the first rotating axis 51 is C1, and the position of the second rotating axis 52 is D1; ​​in the fourth position, point A1 moves to A2, point B1 moves to B2, the position of the first rotating axis 51 is C2, and the position of the second rotating axis 52 is D2; in the second position, point A1 moves to A3, point B1 moves to B3, the position of the first rotating axis 51 is C3, and the position of the second rotating axis 52 is D3; in the third position, point A1 moves to A4, point B1 moves to B4, the position of the first rotating axis 51 is C4, and the position of the second rotating axis 52 is D4.

[0118] like Figure 32 As shown, during the opening process of the air guide plate 100, the motion trajectory of the first rotating shaft 51 includes the first trajectory segment C1C3 and the second trajectory segment C3C4, and the motion trajectory of the second rotating shaft 52 includes the third trajectory segment D1D3 and the fourth trajectory segment D3D4. The first trajectory segment corresponds to the third trajectory segment, and the second trajectory segment corresponds to the fourth trajectory segment. In other words, when the motion trajectory of the first rotating shaft 51 is the first trajectory segment, the motion trajectory of the second rotating shaft 52 is the third trajectory segment. When the motion trajectory of the first rotating shaft 51 is the second trajectory segment, the motion trajectory of the second rotating shaft 52 is the fourth trajectory segment.

[0119] At least one of the first track segment, the second track segment, the third track segment and the fourth track segment includes a curved segment, the first track segment and the second track segment do not overlap, and the third track segment and the fourth track segment do not overlap.

[0120] During the opening process of the wind deflector 100, when the first rotating shaft 51 moves along the first track segment, the second rotating shaft 52 moves along the third track segment, and when the first connecting rod 2 moves along the second track segment, the second connecting rod 4 moves along the fourth track segment. In this way, the first connecting rod 2 and the second connecting rod 4 are both in motion and there is no static state. Therefore, under the joint drive of the first connecting rod 2 and the second connecting rod 4, the position of the wind deflector 100 can be changed to a large extent, so that the wind deflector 100 can have a variety of wind-guiding positions with large position differences. The first track segment and the second track segment do not overlap. In other words, during the opening process of the wind deflector 100, the first connecting rod 2 does not move in the opposite direction. The third track segment and the fourth track segment do not overlap. In other words, during the opening process of the wind deflector 100, the second connecting rod 4 does not move in the opposite direction. This avoids the phenomenon of the wind deflector 100 being stuck during movement due to the opposite movement of the first connecting rod 2 and the second connecting rod 4.

[0121] Optionally, the curved segment is arc-shaped.

[0122] At least one of the first track segment, the second track segment, the third track segment and the fourth track segment includes an arc, which can simplify the movement process of the first connecting rod 2 and the second connecting rod 4, thereby simplifying the design of the driving device for the air conditioning guide plate 100.

[0123] Optionally, both the first track segment and the second track segment are arc segments, and the first track segment and the second track segment have different curvatures.

[0124] The first track segment and the second track segment are both arc-shaped segments, which can further simplify the movement process of the first connecting rod 2, thereby further simplifying the design of the driving device for the air-conditioning air guide plate 100.

[0125] The curvatures of the first trajectory segment and the second trajectory segment are different, so that when the first rotating shaft 51 switches from moving along the first trajectory segment to moving along the second trajectory segment, the first rotating shaft 51 will deflect to a large extent, thereby driving the position of the wind guide plate 100 to change to a large extent, thereby realizing the diversity of the wind guide position of the wind guide plate 100.

[0126] The third track segment and the fourth track segment are both arc segments, and the third track segment and the fourth track segment have different curvatures.

[0127] The third track segment and the fourth track segment are both arc segments, which can further simplify the movement process of the second connecting rod 4, thereby further simplifying the design of the driving device for the air-conditioning air guide plate 100.

[0128] The curvatures of the third trajectory segment and the fourth trajectory segment are different, so that when the second rotating shaft 52 switches from moving along the third trajectory segment to moving along the fourth trajectory segment, the second rotating shaft 52 will deflect to a large extent, thereby driving the position of the wind guide plate 100 to change to a large extent, thereby realizing the diversity of the wind guide position of the wind guide plate 100.

[0129] Alternatively, as Figure 32 As shown, during the opening process of the air guide plate 100 , the first rotation axis 51 passes through the first track segment and the second track segment in sequence, and the curvature of the first track segment is smaller than the curvature of the second track segment.

[0130] When the first rotating shaft 51 moves along the first track segment, since the wind deflector 100 starts to move from the closed position at this time, the wind deflector 100 needs to leave the air outlet first and then deflect. The required deflection degree of the wind deflector 100 is small. Therefore, the curvature of the first track segment is designed to be small, and the length of the first track segment is greater than the length of the second track segment. Within the same motion stroke, compared with moving along the first track segment, when the first rotating shaft 51 moves along the second track segment, the deflection degree of the first rotating shaft 51 will be greater, thereby changing the flip angle of the wind deflector 100 to a greater extent. At this time, what the wind deflector 100 needs is to be able to have a variety of wind-guiding positions (target positions) with large differences. Therefore, the curvature of the second track segment is designed to be large and the length of the second track segment is designed to be small, so that the first connecting rod 2 can deflect by a large angle within a smaller stroke.

[0131] like Figure 32 As shown, the second track segment is located on the side of the first track segment toward the center of curvature thereof.

[0132] Compared with the second track segment extending along the length direction of the first track segment, the second track segment is located on one side of the first track segment, which can reduce the space occupied by the movement process of the first connecting rod 2, thereby reducing the space occupied by the driving device for the air-conditioning air guide plate 100.

[0133] like Figure 32 As shown, the fourth track segment is located on the side of the third track segment away from the center of curvature thereof (the third track segment).

[0134] Compared with the fourth track segment extending along the length direction of the third track segment, the fourth track segment is located on one side of the third track segment, which can reduce the space occupied by the movement process of the second connecting rod 4, thereby reducing the space occupied by the driving device for the air-conditioning air guide plate 100.

[0135] The second track segment is located on the side of the first track segment toward the center of curvature thereof (the first track segment), and the fourth track segment is located on the side of the third track segment away from the center of curvature thereof. This can satisfy that when the first rotating shaft 51 moves along the second track segment and the second rotating shaft 52 moves along the fourth track segment, the first rotating shaft 51 and the second rotating shaft 52 rotate around the same center point, further simplifying the movement trajectories of the first rotating shaft 51 and the second rotating shaft 52, and reducing the design difficulty of the driving device for the air-conditioning air guide plate 100.

[0136] like Figure 32As shown, during the opening process of the air guide plate 100 , the second rotation axis 52 passes through the third track segment and the fourth track segment in sequence, and the curvature of the third track segment is smaller than the curvature of the fourth track segment.

[0137] When the second rotating shaft 52 moves along the third track segment, since the wind guide plate 100 starts to move from the closed position at this time, the wind guide plate 100 needs to leave the air outlet first and then deflect. The degree of deflection required by the wind guide plate 100 is small. Therefore, the curvature of the third track segment is designed to be smaller, and the length of the third track segment is greater than the length of the fourth track segment; within the same movement stroke, compared with moving along the third track segment, when the second rotating shaft 52 moves along the fourth track segment, the degree of deflection of the second rotating shaft 52 will be greater, thereby being able to change the flipping angle of the wind guide plate 100 to a greater extent, and at this time what the wind guide plate 100 needs to be able to have a variety of wind-guiding positions (target positions) with large differences, therefore, the curvature of the fourth track segment is designed to be larger and the length of the fourth track segment is smaller, so that the second connecting rod 4 can be deflected at a larger angle within a smaller stroke.

[0138] The first track segment and / or the third track segment include a curve segment. Figure 32 As shown, the first track segment and / or the third track segment are curved.

[0139] Optionally, the first track segment and / or the third track segment is arc-shaped, which can simplify the motion trajectory of the first connecting rod 2 and / or the second connecting rod 4, thereby simplifying the design of the driving device for the air conditioning deflector 100.

[0140] The curvature centers of the first track segment and the third track segment are located on the same side of the first track segment, so that the first connecting rod 2 and the second connecting rod 4 cooperate to drive the air deflector 100 to move from the first position to the second position.

[0141] Optionally, the first trajectory segment is in an arc shape. This setting can simplify the motion trajectory of the first rotating shaft 51 and simplify the design of the driving device for the air-conditioning air guide plate 100.

[0142] The third trajectory segment is in an arc shape. This setting can simplify the motion trajectory of the second rotating shaft 52 and simplify the design of the driving device for the air-conditioning guide plate 100.

[0143] Optionally, during the opening process of the air deflector 100, the first rotating shaft 51 passes through the first track segment and the second track segment in sequence; and / or during the opening process of the air deflector 100, the second rotating shaft 52 passes through the third track segment and the fourth track segment in sequence.

[0144] like Figure 32 As shown, the second track segment and the fourth track segment are both curved, and the centers of curvature of the second track segment and the fourth track segment coincide.

[0145] In this way, at the same time, the first rotating shaft 51 and the second rotating shaft 52 rotate around the same point (the center of curvature of the second trajectory segment and the fourth trajectory segment), so that the air guide plate 100 also rotates, thereby greatly changing the position of the air guide plate 100, so that when the air guide plate 100 moves from the second position to the third position, the rotation amplitude of the air guide plate 100 is larger, so as to meet the different air supply needs of users.

[0146] The second track segment and the fourth track segment are both arc-shaped, thereby simplifying the motion trajectories of the first connecting rod 2 and the second connecting rod 4 and simplifying the design of the driving device for the air-conditioning guide plate 100 .

[0147] like Figure 32 As shown, the second track segment is an arc-shaped, the fourth track segment is an arc-shaped, the centers of the second track segment and the fourth track segment coincide with each other, and the center of the coincidence is point E. In other words, when the second track segment is an arc-shaped and the fourth track segment is an arc-shaped, the center of curvature of the second track segment and the fourth track segment is the center E of the second track segment and the fourth track segment. During the opening process of the air guide plate 100, the first rotating shaft 51 passes through the first track segment and the second track segment in sequence. The starting point of the first track segment is C1 and the end point is C3. The starting point of the second track segment is C3 and the end point is C4. During the opening process of the air guide plate 100, the first connecting rod 2 moves from C1 to C3 along the first track segment C1C3, so that the air guide plate 100 moves to the first maximum air supply position, and then moves along the second track segment C3C4 from C3 to C4. The second track segment is designed to be an arc shape. On the one hand, it can enable the air guide plate 100 to flip at a larger angle. On the other hand, it can simplify the movement trajectory of the first connecting rod 2, and also make the design of the driving device for the air-conditioning air guide plate 100 simpler.

[0148] During the opening process of the air guide plate 100, the second rotating shaft 52 passes through the third track segment and the fourth track segment in sequence. The starting point of the third track segment is D1 and the end point is D3. The starting point of the fourth track segment is D3 and the end point is D4. During the opening process of the air guide plate 100, the second connecting rod 4 moves from D1 to D3 along the third track segment D1D3, so that the air guide plate 100 moves to the first maximum air supply position, and then moves along the fourth track segment D3D4 from D3 to D4, so that the air guide plate 100 reaches the second maximum air supply position. Therefore, the fourth track segment is designed to be an arc shape. The fourth track segment is designed to be an arc shape. On the one hand, it can enable the air guide plate 100 to flip at a larger angle. On the other hand, it can simplify the movement trajectory of the second connecting rod 4, and also make the design of the driving device for the air-conditioning air guide plate 100 simpler.

[0149] Alternatively, as Figure 32 As shown, the radii of the second track segment and the fourth track segment are equal and their centers coincide.

[0150] In this way, when the first rotating shaft 51 moves along the second track segment and the second rotating shaft 52 moves along the fourth track segment, the first connecting rod 2 and the second connecting rod 4 can drive the air guide plate 100 to flip at a large angle, so that the angle of the air guide plate 100 can change significantly.

[0151] Moreover, the air guide plate 100 is flipped, which can realize both horizontal blowing for cooling and downward blowing for heating, and can meet different usage requirements and improve the user experience.

[0152] The line connecting the starting point and the end point of the second track segment passes through the center of curvature, and the line connecting the starting point and the end point of the fourth track segment passes through the center of curvature.

[0153] As the first rotation axis 51 moves along the starting point C3 of the second trajectory segment to the end point C4, and the second rotation axis 52 moves along the starting point D3 of the fourth trajectory segment to the end point D4, the line connecting points C3 and C4 passes through the center of curvature, and the line connecting points D3 and D4 passes through the center of curvature. This indicates that the first rotation axis 51 and the second rotation axis 52 have rotated 180° around the center of curvature, respectively. This causes the position of the air deflector 100 to flip 180°. When both the second and fourth trajectory segments are arc-shaped, the line connecting points C3 and C4 represents the diameter of the second trajectory segment, and the line connecting points D3 and D4 represents the diameter of the fourth trajectory segment.

[0154] It can be understood that the line connecting the starting point and the end point of the second trajectory segment may not pass through the center of curvature, and the line connecting the starting point and the end point of the fourth trajectory segment may not pass through the center of curvature. In this way, when the first rotating axis 51 moves along the starting point C3 of the second trajectory segment to the end point C4, and the second rotating axis 52 moves along the starting point D3 of the fourth trajectory segment to the end point D4, the position of the air guide plate 100 flips less than 180° or greater than 180°.

[0155] Optionally, the curvature radii of the second track segment and the fourth track segment are equal, so that the first rotation axis 51 and the second rotation axis 52 can flip around the curvature center of the second track segment and the fourth track segment, so that the air deflector 100 rotates around the curvature center.

[0156] When the second track segment and the fourth track segment are both arc-shaped, the second track segment and the fourth track segment have the same radius.

[0157] Alternatively, as Figure 32 As shown, the second track segment and the fourth track segment partially overlap to reduce the space occupied by the first connecting rod 2 and the second connecting rod 4 during movement.

[0158] Optionally, the distance between the first rotation axis 51 and the second rotation axis 52 is less than or equal to the curvature radius of the first track segment.

[0159] The distance between the first rotation axis 51 and the second rotation axis 52 is the length of C1D1, C2D2, C3D3, or C4D4. The distance between the first rotation axis 51 and the second rotation axis 52 is less than or equal to the radius of curvature of the first track segment, so that the radius of curvature of the second and fourth track segments are equal and their centers of curvature coincide, thereby achieving the required position of the air deflector 100.

[0160] The first rotating shaft 51 and the second rotating shaft 52 are substantially sequentially arranged along the thickness direction of the air guide plate 100 .

[0161] Optionally, when the air guide plate 100 moves from the closed position to the first maximum air supply position, the movement trajectory of the first rotating shaft 51 includes a first trajectory segment, and after the first maximum air supply position, the movement trajectory of the first rotating shaft 51 includes a second trajectory segment, so that after the first maximum air supply position, the air guide plate 100 can be deflected at a large angle.

[0162] When the air guide plate 100 moves from the closed position to the first maximum air supply position, the movement trajectory of the second rotating shaft 52 includes a third trajectory segment, and after the first maximum air supply position, the movement trajectory of the second rotating shaft 52 includes a fourth trajectory segment. In this way, after the first maximum air supply position, the air guide plate 100 can be deflected at a large angle.

[0163] Optionally, the driving device for the air-conditioning air guide plate 100 further includes a rotating member, which is directly driven and connected to both the first connecting rod 2 and the second connecting rod 4.

[0164] The first connecting rod 2 is an integral structure and is directly rotatably connected to the air deflector 100 via the first rotating shaft 51 , and / or the second connecting rod 4 is an integral structure and is directly rotatably connected to the air deflector 100 via the second rotating shaft 52 .

[0165] The rotating part includes a gear 1 and a turntable 3. The rotating part is directly driven and connected to the first connecting rod 2 and the second connecting rod 4, which means that the gear 1 is directly engaged with the first connecting rod 2 without any third component in between, and the turntable 3 is directly slidably connected to the second connecting rod 4 through the drive shaft and the drive groove without any third component in between.

[0166] The first connecting rod 2 can be made into an integral structure and directly connected to the air guide plate 100 through the first rotating shaft 51, without the need to set up other additional connecting rods, thereby avoiding interference between the air guide plate 100 and the shell 10 during the opening process of the air guide plate 100. The second connecting rod 4 can also be made into an integral structure and directly connected to the air guide plate 100 through the second rotating shaft 52, without the need to set up other additional connecting rods, thereby avoiding interference between the air guide plate 100 and the shell 10 during the opening process of the air guide plate 100.

[0167] The first link 2 and the second link 4 are rotatably connected to the wind guide plate 100 through the first rotating shaft 51 and the second rotating shaft 52 respectively, which simplifies the connection method between the first link 2 and the wind guide plate 100 and the connection method between the second link 4 and the wind guide plate 100. In this way, the first link 2 and / or the second link 4 do not need to be slidingly connected to the wind guide plate 100, nor is there any need to add other links between the first link 2 and the wind guide plate 100 or between the second link 4 and the wind guide plate 100 as in the related art.

[0168] Optionally, the driving device for the air-conditioning air guide plate 100 includes a rack, which is meshed with the gear 1 and is rotationally connected to the air guide plate 100 through the first rotating shaft 51 to drive the air guide plate 100 to open and close, wherein the rack is the first connecting rod 2.

[0169] like Figure 32 As shown, when the air guide plate 100 opens from the second position to the third position, the first rotating shaft 51 rotates around the center point, that is, around point E, and the motion trajectory is the second trajectory segment. The pitch line of the rack includes the second segment F3F4; wherein the second segment is an arc shape.

[0170] The rack includes a second tooth portion 22. When the air guide plate 100 is opened from the second position to the third position, Figure 16 、 Figure 21 and Figure 26 As shown, the second tooth portion 22 is meshed with the gear 1, and the motion trajectory of the first rotating shaft 51 is the second trajectory segment, as shown in FIG. Figure 33 As shown, the pitch line of the rack corresponding to the second tooth portion 22 is the second segment F3F4, which is arc-shaped. In this way, the meshing of the second tooth portion 22 and the gear 1 satisfies the second trajectory segment to be arc-shaped. The second segment F3F4 enables the rack to perform planar motion according to the trajectory shape of the second trajectory segment C3C4.

[0171] Optionally, the sum of the diameter of the gear 1 and the diameter of the second track segment is the diameter of the second segment F3F4, so that the first rotation axis 51 can move along the second track segment.

[0172] Optionally, when the air guide plate 100 is in the second position, the line connecting the center of the second segment F3F4 and the center of the gear 1 passes through the starting point of the second segment.

[0173] The second segment starts at F3 and ends at F4. When the air guide plate 100 is in the second position, the line connecting the center of the second segment and the center of the gear 1 passes through F3, so that the first rotation axis 51 can move along the second track segment.

[0174] Alternatively, as Figure 33As shown, in the process of the air guide plate 100 opening from the first position to the second position, the motion trajectory of the first rotating shaft 51 includes a first trajectory segment, the first trajectory segment is arc-shaped, and the pitch line of the rack includes a first segment F1F2, the first segment and the second segment are connected and arranged in sequence along the length direction of the rack; the first segment F1F2 is arc-shaped, wherein the starting point of the first segment is F1 and the end point is F2.

[0175] The rack includes a first tooth portion 21, and the first tooth portion 21 and the second tooth portion 22 are connected and arranged in sequence along the length direction of the rack. Figure 13 As shown, during the process of the air guide plate 100 opening from the first position to the second position, the first tooth portion 21 engages with the gear 1, the motion trajectory of the first rotating shaft 51 is the first trajectory segment, and the node line on the rack corresponding to the first tooth portion 21 is the first segment, and the first segment is an arc shape. In this way, the engagement of the first tooth portion 21 with the gear 1 satisfies the first trajectory segment being an arc shape.

[0176] Optionally, the first segment and the first trajectory segment are cocentric to meet the requirements of the motion trajectory of the rack.

[0177] Alternatively, when the line C3E connecting the start point C3 and the center point E of the second trajectory segment C3C4 is parallel to the normal of the first segment passing through the end point F2 of the first segment F1F2, the first segment F1F2 and the second segment F3F4 are directly connected, i.e., points F2 and F3 coincide. Furthermore, the first segment F1F2 and the second segment F3F4 are tangent at point F2.

[0178] Optionally, when the line C3E connecting the starting point C3 and the center point E of the second trajectory segment C3C4 is not parallel to the normal direction of the first segment passing through the end point F2 of the first segment F1F2, the pitch line of the rack also includes a transition segment F2F3 connecting the first segment F1F2 and the second segment F3F4.

[0179] Alternatively, as Figure 33 As shown, the transition section F2F3 is tangent to the first section F1F2 and tangent to the second section F3F4; and / or the transition section F2F3 is a partial pitch circle of the gear 1.

[0180] Gear 1 is a circular gear. Transition segment F2F3 is an arc on the pitch circle of gear 1, designed based on the position of the rotation center E of air deflector 100. When C3E is parallel to the normal direction of the first segment F1F2 passing through point F2, the air deflector 100 can rotate, and transition segment F2F3 is not required. When C3E is not parallel to the normal direction of the first segment F1F2 passing through point F2, transition segment F2F3 is required to ensure that the first rotation axis 51 rotates around the center E from point C3 when the first rotation axis 51 moves from C3 to C4.

[0181] In the case where the pitch line of the rack includes the transition section F2F3 , the rack further includes a transition tooth portion 23 , which can also mesh with the gear 1 .

[0182] like Figure 6 and Figure 7 As shown, the driving device for the air-conditioning air guide plate 100 also includes a first guide member 6, the first guide member 6 is provided with a plurality of first guide portions 61, and the first connecting rod 2 is provided with a plurality of first guide matching portions 24. The first guide portion 61 cooperates with the first guide matching portion 24 to guide the movement of the first connecting rod 2 so that the first connecting rod 2 can move along a predetermined trajectory.

[0183] The number of the first guide portions 61 and the first guide matching portions 24 are equal and correspond one to one. Figure 6 As shown, the number of the first guide portions 61 and the number of the first guide matching portions 24 are both two.

[0184] Optionally, one of the first guide portion 61 and the first guide matching portion 24 is a first guide groove 62 , and the other is a first guide post 241 . The first guide post 241 is located in the first guide groove 62 and can slide relative to the first guide groove 62 .

[0185] Each first guide groove 62 includes a first guide section 621. Figure 10 、 Figure 19 As shown, when the air deflector 100 is opened from the first position to the second position, the first guide column 241 is located in the first guide section 621 and can move relative to the first guide section 621 .

[0186] The first guide segment 621 is arc-shaped, and the first guide segments 621 on the plurality of first guide grooves 62 are concentric circles or located on the same circumference to satisfy the motion trajectory of the first connecting rod 2 .

[0187] like Figure 19 As shown, there are two first guide grooves 62 and two first guide posts 241 . The two first guide grooves 62 each include a first guide segment 621 . The first guide segments 621 of the two first guide grooves 62 are concentric circles or located on the same circumference.
