DETAILED DESCRIPTION

[0052] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0054] In the embodiments of the present disclosure, the terms "upper", "lower", "inside", "middle", "outside", "front", "back" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe the embodiments of the present disclosure and their embodiments, and are not intended to limit the indicated devices, elements or components to having a specific direction, or to be constructed and operated in a specific direction.

[0055] Furthermore, the terms "disposed," "connected," and "fixed" should be interpreted broadly. For example, "connected" can mean a fixed connection, a removable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediary, or an internal connection between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in the embodiments of this disclosure based on the specific circumstances.

[0056] Unless otherwise stated, the term "plurality" means two or more.

[0057] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0058] 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.

[0059] 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.

[0060] Combine Figure 1-30 、 Figure 35 As shown, an embodiment of the present disclosure provides a driving mechanism for an air deflector, including a driving wheel 30 , a first connecting rod 10 and a second connecting rod 20 .

[0061] like Figures 3 to 8 As shown, the driving wheel 30 rotates in a controlled manner, including a first tooth portion 301 and a second tooth portion 302; the first connecting rod 10 includes a first rack 101, which is used to engage with the first tooth portion 301 and is directly connected to the air guide plate 70 through a first rotating shaft 501; the second connecting rod 20 includes a second rack 201, which is used to engage with the second tooth portion 302 and is directly connected to the air guide plate 70 through a second rotating shaft 502.

[0062] The driving wheel 30 drives the first connecting rod 10 and the second connecting rod 20 to move, thereby driving the air guide plate 70 to move, thereby realizing the opening and closing of the air guide plate 70.

[0063] The first connecting rod 10 is an integral structure, directly rotatably connected to the air deflector 70 via a first rotating shaft 501, with no other connecting rod 109 connected between the first connecting rod 10 and the air deflector 70. The second connecting rod 20 is an integral structure, directly rotatably connected to the air deflector 70 via a second rotating shaft 502, with no other connecting rod 109 connected between the second connecting rod 20 and the air deflector 70. Furthermore, both the first connecting rod 10 and the second connecting rod 20 are rotatably connected to the air deflector 70, rather than slidingly connected, thereby preventing wear on the first connecting rod 10 and the second connecting rod 20 during sliding.

[0064] Alternatively, as Figure 8 and Figure 9 As shown, the first tooth portion 301 and the second tooth portion 302 are coaxially arranged and rotate synchronously.

[0065] The rotation axes of the first tooth portion 301 and the second tooth portion 302 coincide and rotate synchronously with each other at the same angular velocity. This simplifies the control of the movement of the first connecting rod 10 and the second connecting rod 20 on the one hand, and the first tooth portion 301 and the second tooth portion 302 can be driven by a motor 407 on the other hand.

[0066] Optionally, the first tooth portion 301 is a non-circular gear, and the second tooth portion 302 is a cylindrical gear.

[0067] This arrangement enables the first connecting rod 10 and the second connecting rod 20 to have different movement speeds and trajectories during the movement process, thereby realizing the complex movement of the air guide plate 70 and better meeting the diverse needs of air conditioning air guidance.

[0068] Through the special shape and transmission characteristics of the non-circular gear, more precise speed control and position adjustment can be achieved during the movement of the air guide plate 70, making the air guiding effect of the air conditioner more ideal and improving user comfort.

[0069] Optionally, the drive mechanism for the air deflector further includes a reduction gear 40, which is connected between the motor 407 and the drive wheel 30. The motor 407 is in driving connection with the reduction gear 40, which meshes with the cylindrical gear, which is fixedly connected to the non-circular gear. The motor 407 drives the reduction gear 40 to rotate, which in turn drives the cylindrical gear, and the non-circular gear rotates with the cylindrical gear.

[0070] like Figure 6 As shown, the reduction gear 40 is a cylindrical gear and the radius of the reduction gear 40 is smaller than the radius of the second tooth portion 302 .

[0071] Alternatively, as Figure 32 As shown, during the opening process of the air guide plate 70, the motion trajectory of the first rotating shaft 501 includes the first trajectory segment A1A2 and the second trajectory segment A2A3, and the motion trajectory of the second rotating shaft 502 includes the third trajectory segment B1B2 and the fourth trajectory segment B2B3. The first trajectory segment A1A2 corresponds to the third trajectory segment B1B2, that is, during the movement of the air guide plate 70, when the first rotating shaft 501 moves along A1A2, the second rotating shaft 502 moves along B1B2, and the second trajectory segment A2A3 corresponds to the fourth trajectory segment B2B3. Correspondingly, that is, during the movement of the air guide plate 70, when the first rotating axis 501 moves along A2A3, the second rotating axis 502 moves along B2B3; wherein, at least one of the first trajectory segment A1A2, the second trajectory segment A2A3, the third trajectory segment B1B2 and the fourth trajectory segment B2B3 is a non-circular curve, so that there is deflection during the movement of the first connecting rod 10 and / or the second connecting rod 20, so that the air guide plate 70 can achieve a complex movement mode and better adapt to the shape and air guide requirements of the air-conditioning outlet 404.

[0072] Optionally, the first track segment A1A2 and the third track segment B1B2 are both arc-shaped.

[0073] This setting can simplify the motion trajectory of the first connecting rod 10 and the second connecting rod 20, making the control logic of the driving mechanism for the air guide plate simpler, facilitating precise motion control, improving the reliability and stability of the system, and also making the movement of the air guide plate 70 in the initial opening stage smoother, reducing jitter and noise during movement.

[0074] Optionally, the second track segment A2A3 is arc-shaped and is two arcs on the same circle as the first track segment A1A2. The two arcs share point A2. This setting makes the movement of the first rotation axis 501 more coherent, avoiding sudden changes and jams when moving from the first track segment to the second track segment.

[0075] Optionally, during the process of the air guide plate 70 opening from the first position to the second position, the first rotating shaft 501 moves from A1 to A2 along the first trajectory segment A1A2, and the second rotating shaft 502 moves from B1 to B2 along the third trajectory segment B1B2; during the process of the air guide plate 70 opening from the second position to the third position, the first rotating shaft 501 reciprocates along the second trajectory segment A2A3, and the second rotating shaft 502 moves from B2 to B3 along the fourth trajectory segment B2B3.

[0076] There may be a fourth position between the first position and the second position, and a fifth position between the second position and the third position. The wind deflector 70 passes through the first position, the fourth position, the second position, the fifth position and the third position in sequence during the opening process. Figures 1 to 30 As shown, the first position is the closed position, the fourth position is the cooling horizontal blowing position, the second position is the maximum air supply position, the fifth position is the surrounding air supply position, and the third position is the heating downward blowing position. Alternatively, the fourth position is the heating downward blowing position, and the third position is the cooling horizontal blowing position.

[0077] When the air deflector 70 opens from the second position to the third position, the first rotating shaft 501 reciprocates along the second trajectory segment A2A3. This reciprocating motion effectively reduces the space occupied by the first connecting rod 10 during its movement. Compared to traditional unidirectional motion, this reciprocating motion prevents the first connecting rod 10 from overstretching during movement, thereby reducing the installation space required for the air deflector's drive mechanism within the indoor unit 80.

[0078] Alternatively, as Figure 32 As shown, the fourth trajectory segment B2B3 is a non-circular curve, which cooperates with the reciprocating motion of the first rotating shaft 501 along the second trajectory segment A2A3, moving from A2 to A3, and then from A3 to A2, for one or more cycles to realize the flipping of the air guide plate 70 from the second position to the third position.

[0079] Optionally, when the second rotation axis 502 moves along the fourth track segment B2B3 , the second rotation axis 502 rotates and revolves around the first rotation axis 501 .

[0080] During the movement of the air deflector 70 from the second position to the third position, the center of rotation of the second rotation axis 502 is the position of the first rotation axis 501 corresponding to the current position of the second rotation axis 502. Correspondence means that at the same moment when the second rotation axis 502 is at position B7, the first rotation axis 501 is at position A7, where B7 is B2, B3, or a point between B2 and B3 in the second trajectory segment B2B3, and A7 is A2, A3, or a point between A2 and A3 in the second trajectory segment A2A3. During the movement of the air deflector 70, the position of the first rotation axis 501 is not fixed. Therefore, the position of the center of rotation of the second rotation axis 502 is also not fixed. In conjunction with the rotation of the second rotation axis 502, the air deflector 70 is flipped from the second position to the third position.

[0081] Optionally, when the second rotation axis 502 moves along the fourth track segment B2B3 , the instantaneous rotation center of the second rotation axis 502 is the position of the first rotation axis 501 corresponding to the current position of the second rotation axis 502 .

[0082] Optionally, when the second rotation axis 502 moves along the fourth track segment B2B3 , the movement tracks of various points on the second connecting rod 20 located on the same plane are different, where the plane is the longitudinal section of the second connecting rod 20 .

[0083] This arrangement allows the second connecting rod 20 to perform planar motion, that is, to move within the plane of the longitudinal section of the second connecting rod 20. Because the speeds and motion trajectories of various points on the second connecting rod 20 located in the same plane differ when the second rotating shaft 502 moves along the fourth trajectory segment B2B3, the second connecting rod 20 does not perform translational motion, but rather a combination of movement and rotation, with the instantaneous rotation center of each point located in the same plane constantly changing. This, in conjunction with the movement of the first rotating shaft 501, enables the air deflector 70 to move from the second position to the third position.

[0084] Alternatively, as Figure 12 and Figure 16 As shown, the second link 20 includes a second link guide portion 202 and a third link guide portion 204. During the opening process of the air guide plate 70, the second link guide portion 202 moves back and forth, which shortens the extension distance of the second link 20, reduces the size of the second link 20, and ensures the strength of the second link 20; the third link guide portion 204 moves unidirectionally.

[0085] The third link guide portion 204 performs unidirectional motion, and the second link guide portion 202 has reciprocating motion in its motion trajectory. Through the reciprocating motion of the second link guide portion 202 and the unidirectional motion of the third link guide portion 204, the second link 20 can achieve a complex motion trajectory, thereby enabling the air guide plate 70 to achieve a complex motion mode during the opening process, thereby meeting the diverse requirements of the air conditioner for air guide direction and angle under different working conditions.

[0086] Optionally, the second link guide portion 202 is located between the third link guide portion 204 and the second rotating shaft 502, and the motion trajectory of the second rotating shaft 502, the motion trajectory of the second link guide portion 202, and the motion trajectory of the third link guide portion 204 are jointly realized to meet the movement requirements of the air guide plate 70.

[0087] Optionally, when the air guide plate 70 opens from the first position to the second position, the second link guide portion 202 and the third link guide portion 204 both perform unidirectional movement.

[0088] When the air deflector 70 opens from the first position (closed position) to the second position (maximum air supply position), the second link guide portion 202 and the third link guide portion 204 both move in one direction. This design simplifies the motion control logic of the first link 10 and the second link, facilitates precise motion control, and reduces the complexity of the control system.

[0089] Alternatively, as Figures 1 to 18 As shown, in the process of the air guide plate 70 opening from the first position to the second position, the movement trajectories of the second link guide portion 202 and the third link guide portion 204 are the same, wherein the same movement trajectory means that the movement trajectories can completely overlap after translation, making the movement of the air guide plate 70 more stable and consistent, avoiding jitter and jamming during movement, and improving the uniformity and reliability of the air guide.

[0090] Alternatively, as Figures 18 to 30 As shown, in the process of the air guide plate 70 opening from the second position to the third position, the third link guide portion 204 and the second rotating shaft 502 have reverse movement or movement with an opposite movement trend, or there is a moment at which the angle between the third link guide portion 204 and the movement direction of the second rotating shaft 502 is greater than 90°, so that the second link 20 can deflect at a large angle instead of moving horizontally, thereby enabling the air guide plate 70 to be flipped when the stroke of the second link 20 is small, so that the air guide plate 70 can be switched from the second position to the third position.

[0091] Optionally, during the process of opening the air guide plate 70 from the second position to the third position, the movement trajectories of the second link guide portion 202 and the third link guide portion 204 are different, so that the second link 20 can be deflected instead of translated, thereby realizing the switching of the air guide plate 70 from the second position to the third position.

[0092] like Figure 1 and Figure 2As shown, the drive mechanism for the air deflector further includes a mechanism box 6, which includes a first box cover 61 and a second box cover 62 that are arranged opposite and assembled. The first box cover 61 and the second box cover 62 together define a storage space, and the first connecting rod 10, the second connecting rod 20, the driving wheel 30, and the reduction wheel 40 are collectively located in the storage space. The first connecting rod 10 and the second connecting rod 20 are arranged in sequence along the direction from the first box cover 61 to the second box cover 62.

[0093] The second box cover 62 includes a second box cover guide portion 621 , which cooperates with the second connecting rod guide portion 202 to guide the movement trajectory of the second connecting rod 20 to drive the air guide plate 70 to move along a set trajectory.

[0094] The second box cover 62 further includes a third box cover guide portion 625 , which cooperates with the third connecting rod guide portion 204 , and the second box cover guide portion 621 cooperates with the second connecting rod guide portion 202 to jointly guide the motion trajectory of the second connecting rod 20 .

[0095] like Figure 14 As shown, one of the second box cover guide portion 621 and the second connecting rod guide portion 202 is the second guide groove 622, and the other is the second guide column 203, the second guide column 203 is adapted to the second guide groove 622, the second guide column 203 is located in the second guide groove 622 and can slide relative to the second guide groove 622; one of the third box cover guide portion 625 and the third connecting rod guide portion 204 is the third guide groove 626, and the other is the third guide column 205, the third guide column 205 is adapted to the third guide groove 626, the third guide column 205 is located in the third guide groove 626 and can slide relative to the third guide groove 626.

[0096] In the process of the air guide plate 70 opening from the first position to the second position, the movement direction of the second rotating shaft 502, the movement direction of the second connecting rod guide part 202, and the movement direction of the third connecting rod guide part 204 are all the same, and the movement trajectory of the second rotating shaft 502, the movement trajectory of the second connecting rod guide part 202, and the movement trajectory of the third connecting rod guide part 204 are all the same, that is, after translation, the movement trajectory of the second rotating shaft 502, the movement trajectory of the second connecting rod guide part 202, and the movement trajectory of the third connecting rod guide part 204 can overlap.

[0097] The second guide groove 622 includes a first sub-guide groove 623 and a second sub-guide groove 624 which are sequentially arranged and connected along the length direction of the second guide groove 622. During the process of the air guide plate 70 opening from the first position to the third position, the second guide column 203 passes through the first sub-guide groove 623 and the second sub-guide groove 624 in sequence; the third guide groove 626 includes a third sub-guide groove 627, a fourth sub-guide groove 628 and a fifth sub-guide groove 629 which are sequentially arranged and connected along the length direction of the third guide groove 626. During the process of the air guide plate 70 opening from the first position to the third position, the third guide column 205 passes through the third sub-guide groove 627, the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence.

[0098] like Figures 1 to 18 As shown, in the process of the air guide plate 70 opening from the first position to the second position, the movement trajectory of the second rotating shaft 502 is B1B2, which is an arc shape, and the second guide column 203 is located in the first sub-guide groove 623 and can slide unidirectionally relative to the first sub-guide groove 623, and the third guide column 205 is located in the third sub-guide groove 627 and can slide unidirectionally relative to the third sub-guide groove 627, that is, the second guide column 203 cooperates with the first sub-guide groove 623, and the third guide column 205 cooperates with the third sub-guide groove 627. The first sub-guide groove 623 and the third sub-guide groove 627 are both arc-shaped, and the shape is the same as B1B2. The first sub-guide groove 623, the third sub-guide groove 627 and B1B2 can be different arc segments on the same circle or located on concentric circles.

[0099] like Figures 19 to 30As shown, in the process of the air guide plate 70 opening from the second position to the third position, the movement trajectory of the second rotating shaft 502 is B2B3, which is a non-circular arc shape, and the second guide column 203 is located in the second sub-guide groove 624 and can reciprocate relative to the second sub-guide groove 624 along the length direction of the second sub-guide groove 624, and the third guide column 205 is located in the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence and can slide unidirectionally relative to the fourth sub-guide groove 628 and the fifth sub-guide groove 629, that is, the second guide column 203 cooperates with the second sub-guide groove 624, and the third guide column 205 cooperates with the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence. When the third guide column 205 cooperates with the fourth sub-guide groove 628, the third guide column 205 and the second rotating shaft 502 have reverse movement, and when the third guide column 205 cooperates with the low-speed sub-guide groove, the third guide column 205 and the second rotating shaft 502 have the same direction movement. The second sub-guide groove 624 can be arc-shaped. In this case, the second sub-guide groove 624 and the first sub-guide groove 623 are located on the same circle or on different circles. The fourth sub-guide groove 628 and the fifth sub-guide groove 629 can be arc-shaped or not. The fourth sub-guide groove 628 and the fifth sub-guide groove 629 are both located on the same side of the third sub-guide groove 627.

[0100] like Figure 32 As shown, the second connecting rod 20 includes a second tooth segment 207 for meshing with the second tooth portion 302. The pitch lines B5B6 of the second tooth segment 207 are non-circular curves, so that the rotation center of the second connecting rod 20 is not a fixed point during the meshing of the second tooth portion 302 and the second tooth segment 207. During the meshing of the second tooth portion 302 and the second tooth segment 207, the wind deflector 70 moves from the second position to the third position, and the corresponding motion trajectory of the second rotation axis 502 is a non-circular trajectory B2B3.

[0101] The non-circular pitch curve of the second tooth segment 207 enables the air deflector 70 to move in a variety of complex motion paths. This design overcomes the limitations of traditional circular arc gear transmissions, making the air deflector 70 more flexible and diverse in motion, better adapting to the needs of the air conditioner in different operating modes.

[0102] The pitch line design of the second tooth segment 207 eliminates a fixed center of rotation for the second connecting rod 20 during movement. This dynamic center of rotation design enables more complex movement patterns. For example, during the opening of the air deflector 70, the second connecting rod 20 can be adjusted in multiple directions as needed to achieve a more ideal air supply effect.

[0103] Optionally, the nodal line of the second tooth segment 207 satisfies the following: when the second tooth portion 302 is engaged with the second tooth segment 207, the velocities and angular velocities of each point on the same plane of the second connecting rod 20 are different, wherein the plane is the longitudinal section of the second connecting rod 20, so that the second connecting rod 20 does not perform translational motion but deflects, so as to realize multiple wind-guiding positions of the wind guide plate 70.

[0104] Optionally, the nodal line of the second tooth segment 207 satisfies: when the second tooth portion 302 is engaged with the second tooth segment 207, the motion trajectories of the points on the second connecting rod 20 located on the same plane are different, wherein the plane is the longitudinal section of the second connecting rod 20, so that the second connecting rod 20 does not perform translational motion but deflects, so as to realize multiple wind-guiding positions of the wind guide plate 70.

[0105] Optionally, the second connecting rod 20 also includes a second connecting rod guide portion 202 and a third connecting rod guide portion 204, and the pitch line of the second tooth segment 207 satisfies: when the second tooth portion 302 is engaged with the second tooth segment 207, during the opening process of the air guide plate 70, the second connecting rod guide portion 202 has reciprocating motion and the third connecting rod guide portion 204 has unidirectional motion.

[0106] The pitch line of the second tooth segment 207 satisfies the following conditions: during the meshing of the second tooth portion 302 and the second tooth segment 207, the second rotation axis 502 and the third connecting rod guide portion 204 move in opposite directions. The pitch line of the second tooth segment 207 satisfies the following conditions: during the meshing of the second tooth portion 302 and the second tooth segment 207, the second rotation axis 502 and the third connecting rod guide portion 204 move in the same direction.

[0107] Optionally, the second connecting rod 20 further includes a first tooth segment 206 for meshing with the second tooth portion 302 . The first tooth segment 206 and the second tooth segment 207 are sequentially arranged along the length direction of the second connecting rod 20 . The pitch line B4B5 of the first tooth segment 206 is an arc shape.

[0108] In this way, when the second tooth portion 302 is meshed with the first tooth segment 206 , the motion trajectory of the second rotating shaft 502 is a circular arc trajectory B1B2 .

[0109] During the opening process of the air deflector 70, the second tooth portion 302 sequentially meshes with the first tooth segment 206 and the second tooth segment 207. During the meshing process of the second tooth portion 302 and the first tooth segment 206, the air deflector 70 moves from the first position to the second position.

[0110] Optionally, the pitch line of the first tooth segment 206 satisfies that during the meshing of the second tooth portion 302 with the first tooth segment 206 , the motion trajectories of the second connecting rod guide portion 202 and the third connecting rod guide portion 204 are the same.

[0111] The first box cover 61 is provided with a first box cover guide portion 611, and the first connecting rod 10 is provided with a first connecting rod guide portion 102. One of the first connecting rod guide portion 102 and the first box cover guide portion 611 is a first guide groove 612, and the other is a first guide column 103. The first guide column 103 is adapted to the first guide groove 612. The first guide column 103 is located in the first guide groove 612 and can slide relative to the first guide groove 612 to guide the movement trajectory of the first connecting rod 10.

[0112] When the first rotation axis 501 moves along the first trajectory segment A1A2, the first guide post 103 moves unidirectionally within the first guide slot 612. When the first rotation axis 501 reciprocates along the second trajectory segment A2A3, the first guide post 103 reciprocates within the first guide slot 612. There can be one or more first guide posts 103, and the number of first guide slots 612 is less than or equal to the number of first guide posts 103, such that at least one first guide post 103 is provided within the first guide slot 612. When multiple first guide posts 103 are provided within the first guide slot 612, the multiple first guide posts 103 are arranged sequentially along the length of the first guide slot 612.

[0113] The first connecting rod 10 can perform translational motion, and the motion trajectory of each point on the first connecting rod 10 is the same. The shape of the first guide groove 612 is the same as the motion trajectory of the first rotating shaft 501, that is, after translation, the motion trajectory of the first guide groove 612 and the first rotating shaft 501 can coincide.

[0114] It is understandable that the first connecting rod 10 may not perform translational motion, or may deflect during the motion.

[0115] like Figure 32 As shown, in the closed position of the air guide plate 70, the first rotation axis 501 is located at point A1, and the second rotation axis 502 is located at point B1. A1A2 and A2A3 are both arc-shaped, with the center of the arc being A0. B1B2 is also an arc-shaped, with the center being B0. The rotation center (or center) of the pitch line B4B5 of the first tooth segment 206 is B0. Figure 31 As shown, the pitch line of the second tooth portion 302 is circle B7, the pitch line of the first tooth portion 301 is the non-circular curve A4A6, the pitch line of the second rack 201 is B4B5B6, and the non-circular curve A4A5 is the pitch line of the first rack 101. The non-circular curve A4A6 and the non-circular curve A4A5 are tangent at point A4. The curve combination B4B5B6 is tangent to circle B7 at the initial position (when the air deflector 70 is in the closed position) at point B4. During the segment along the pitch line B4B5, i.e., the entire meshing process between the second tooth portion 302 and the first tooth segment 206, the tangent point remains at point B4. During the segment along the pitch line B5B6, i.e., the meshing process between the second tooth portion 302 and the second tooth segment 207, the tangent point moves along the curve B5B6.

[0116] The nodal line B5B6 is a curve, not an arc, and has no fixed center. Its shape is a curve or spline curve that is tangent to each point on it. During the process of the second tooth portion 302 meshing with the second tooth segment 207, the speed and trajectory of each point on the second connecting rod 20 are different. The second connecting rod 20 performs planar motion, both moving and rotating, and the instantaneous rotation center of each point on the second connecting rod 20 is constantly changing.

[0117] The nodal lines A4A5 and A4A6 are curved and non-circular arcs with no fixed center, but they both have fixed rotation centers, namely A0 and E.

[0118] Circle B7 is concentric with the non-circular curve A4A6, and the rotation center is E; the rotation center of the non-circular curve A4A5 and the circular arc A1A2 are both A0.

[0119] In the present application, the extension and rotation of the air guide plate 70 are achieved by using the different displacement differences between the first rotating shaft 501 and the second rotating shaft 502 .

[0120] The air guide plate 70 changes from the closed position to the cooling flat blowing position to the maximum air supply position:

[0121] The first rotating shaft 501 moves from A1 along the arc A1A3 to A2; the second rotating shaft 502 moves from B1 along the arc B1B2 to B2, and the second tooth portion 302 engages with the first tooth segment 206. That is, the first rotating shaft 501 rotates around A0, and the second rotating shaft 502 rotates around B0, and the distance between the first rotating shaft 501 and the second rotating shaft 502 does not change during the movement.

[0122] The air guide plate 70 changes from the maximum air supply position → the surrounding air supply position → the heating downward blowing position:

[0123] The first rotating shaft 501 moves back and forth along the arc A2A3 starting from A2 and finally moves to A2; the second tooth portion 302 engages with the second tooth segment 207, and the second rotating shaft 502 moves from B2 to B3 along the curve B2B3, wherein the curve B2B3 is not an arc, and its instantaneous rotation center, the first rotating shaft 501, moves back and forth along the arc A2A3 and finally moves to A2.

[0124] Optionally, during the movement of the air guide plate 70, the transmission ratio i between the first tooth portion 301 and the first rack 101 and the angular velocity ω of the first rotating shaft 501 are A and the angular velocity ω of the second rotation axis 502 B There are constraints.

[0125] During the movement of the air deflector 70, the length of the line connecting the first rotating shaft 501 and the second rotating shaft 502 remains unchanged. In this way, when the first rotating shaft 501 and the second rotating shaft 502 move on their respective trajectories, the movement speed of the first rotating shaft 501 and the movement speed of the second rotating shaft 502 must satisfy a certain functional relationship. In other words, during the movement of the air deflector 70, the transmission ratio i between the first tooth portion 301 and the first rack 101 and the angular velocity ω of the first rotating shaft 501 are A and the angular velocity ω of the second rotation axis 502 B There is a constraint relationship, so that in this application, the first connecting rod 10 and the air guide plate 70 are directly rotationally connected through the first rotating shaft 501, and the second connecting rod 20 and the air guide plate 70 are directly rotationally connected through the second rotating shaft 502.

[0126] If the first connecting rod 10 is provided with a sliding column, the air guide plate 70 is provided with a sliding groove, the sliding column is located in the sliding groove and is slidingly connected to the sliding groove, the second connecting rod 20 is directly rotationally connected to the air guide plate 70 through the second rotating shaft 502, and is slidingly connected to the air guide plate 70 through the cooperation of the sliding column and the sliding groove. During the movement of the air guide plate 70, the distance between the sliding column and the second rotating column changes, so the requirements for the relationship between the movement speed of the first rotating shaft 501 and the movement speed of the second rotating shaft 502 are not as strict as in this application.

[0127] Optionally, during the movement of the air deflector, the transmission ratio i between the first tooth portion and the first rack and the angular velocity ω of the first rotating shaft are A and the angular velocity ω of the second rotation axis B There are constraints.

[0128] During the movement of the air deflector, the length of the line connecting the first rotating shaft and the second rotating shaft remains unchanged. In this way, when the first rotating shaft and the second rotating shaft move on their respective trajectories, the movement speed of the first rotating shaft and the movement speed of the second rotating shaft must satisfy a certain functional relationship. In other words, during the movement of the air deflector, the transmission ratio i of the first tooth portion and the first rack and the angular velocity ω of the first rotating shaft are A and the angular velocity ω of the second rotation axis B There is a constraint relationship, so that in this application, the first connecting rod and the air guide plate are directly rotationally connected through the first rotating shaft, and the second connecting rod and the air guide plate are directly rotationally connected through the second rotating shaft.

[0129] If the first connecting rod is provided with a sliding column and the air guide plate is provided with a sliding groove, the sliding column is located in the sliding groove and is slidingly connected to the sliding groove, the second connecting rod is directly rotationally connected to the air guide plate through the second rotating shaft, and is slidingly connected to the air guide plate through the cooperation of the sliding column and the sliding groove. During the movement of the air guide plate, the distance between the sliding column and the second rotating column changes, so the requirements for the relationship between the movement speed of the first rotating shaft and the movement speed of the second rotating shaft are not as strict as in this application.

[0130] With B0 as the coordinate 0 point and B0A0 as the X axis, establish Figure 34 In the coordinate system shown, to simplify the formula, let B0A0=L1, A0A1=L2, A1B1=L3, B0B1=L4, ∠A1A0X=A, ∠B1B0X=B, ∠A1B1X1=C, where B1X1 is parallel to the X-axis, and the angular velocity of the second rotation axis around B0 is ω B , the angular velocity of the first rotation axis around A0 is ω A , the angular velocity of C is ω C ,ω C It can be understood as the angular velocity of the line connecting the first rotation axis and the second rotation axis rotating around the second rotation axis, that is, the rate of change of C. According to the principle of linkage mechanism, it can be obtained:

[0131] L1+L2*cosA=L4*cosB+L3*cosC ①

[0132] L2*sinA=L4*sinB-L3*sinC ②

[0133] The variables in the formula are A, B, and C. Differentiate formulas ① and ② with respect to time T, and we get

[0134] -L2*sinA*ω A =-L4*sinB*ω B -L3*sinC*ω C ③

[0135] L2*cosA*ω A =L4*cosB*ω B -L3*cosC*ω C ④

[0136] Combining equations ① to ④, we can get

[0137]

[0138] Let m = L4*sinB - L2*sinA, n = L1 + L2*cosA - L4*cosB, simplify equation ⑤, and we can get the angular velocity ratio of the second rotation axis to the first rotation axis, which is:

[0139]

[0140] To simplify the design, the second tooth and rack driving the second rotating shaft use a fixed transmission ratio (i.e., uniform speed). Therefore, the radius of the pitch line of the first tooth and rack driving the first rotating shaft can be calculated using Equation 6. Based on the structural position design method, the position of the second tooth's center E and the radius R1 of B7 are determined. The radii of B4 and B5 are the same as the rotation radius L4 of the second rotating shaft.

[0141] Assume that the angular velocity of the driving wheel is ω1, the radius of A4A6 is r1, the radius of A4A5 is r2, and the initial angle of A is θ1, that is, when the wind deflector is in the closed position, A=θ1. The center distance A0E=a, then

[0142]

[0143] Combining equations ⑦ and ⑧, we can get the transmission ratio i of the first tooth portion and the first rack.

[0144]

[0145] The equation of the nodal line A4A6 is:

[0146]

[0147] The equation of the nodal line A4A5 is:

[0148]

[0149] is the angle between the radius of the pitch line of the first rack and the polar axis. is an equation in polar coordinates.

[0150] Combine ⑤, ⑥, ⑨, ⑩, Formula, import mathematical calculation software, write a calculation program, draw the pitch line A4A6 and pitch line A4A5 graphics, import the pitch line graphics into 3D drawing software, and then draw its tooth profile according to the tooth shape design method (for example, the method disclosed in application number CN202310777054.8).

[0151] The above transmission ratio is applicable to the stage when the second rotating shaft moves along B1B2.

[0152] Optionally, the pitch line of the first rack is non-circular arc-shaped, and the pitch line of the second rack is circular arc-shaped.

[0153] like Figure 1 、 Figure 2 and Figure 7As shown, the first box cover 61 is provided with a first limiting portion 613, and the second box cover 62 is provided with a second limiting portion; the second connecting rod 20 is provided with a first limiting matching portion 208 matching with the first limiting portion 613 and a second limiting matching portion matching with the second limiting portion to limit the movement of the second connecting rod 20 in the direction of the line connecting the first box cover 61 and the second box cover 62.

[0154] The first box cover 61 and the second box cover 62 are arranged opposite to each other. Through the cooperation of the first limiting portion 613 of the first box cover 61 and the first limiting matching portion 208, the movement of the second connecting rod 20 toward the first box cover 61 can be limited. Through the cooperation of the second limiting portion and the second limiting matching portion of the second box cover 62, the movement of the second connecting rod 20 toward the second box cover 62 can be limited, thereby achieving accurate limiting of the second connecting rod 20 in the direction of the line connecting the first box cover 61 and the second box cover 62, and the limiting of the second connecting rod 20 is not achieved with the help of the first connecting rod 10, so as to avoid the second connecting rod 20 affecting the movement of the first connecting rod 10.

[0155] Optionally, the first limiting portion 613 includes a limiting area 614 formed by the first box cover 61 protruding toward the second connecting rod 20, which reduces the distance between the limiting area 614 and the second connecting rod 20, thereby facilitating the contact and cooperation between the first limiting portion 613 and the first limiting matching portion 208, and the limiting area 614 can also enhance the strength of the first box cover 61. The first limiting matching portion 208 includes a first limiting column 209 provided on the second connecting rod 20, and the first limiting column 209 abuts against the limiting area 614 and can move relative to the limiting area 614.

[0156] Or the first limiting fitting portion 208 includes a limiting area 614 formed by the second connecting rod 20 protruding toward the first box cover 61, which reduces the distance between the limiting area 614 and the first box cover 61, thereby facilitating the contact and cooperation between the first limiting portion 613 and the first limiting fitting portion 208, and the limiting area 614 can also enhance the strength of the second connecting rod 20. The first limiting portion 613 includes a first limiting column 209 provided on the first box cover 61, and the first limiting column 209 abuts against the limiting area 614 and can move relative to the limiting area 614.

[0157] During the opening process of the air guide plate 70, the second connecting rod 20 moves, and the first limiting fitting part 208 moves with the second connecting rod 20. Therefore, the size of the limiting area 614 needs to meet the full range of movement of the first limiting fitting part 208, and the limiting area 614 can always be in contact with the first limiting fitting part 208.

[0158] Alternatively, as Figure 2 As shown, the limiting area 614 is planar, ensuring that the first limiting column 209 can always be in contact with the limiting area 614 during the movement.

[0159] Optionally, there are multiple first limiting columns 209. During the movement of the second connecting rod 20, at least one of the multiple first limiting columns 209 abuts against the limiting area 614. On the one hand, when the multiple first limiting columns 209 contact the limiting area 614, the limiting effect on the second connecting rod 20 can be enhanced. On the other hand, multiple first limiting columns 209 are set. As long as there is one first limiting column 209 in contact with the limiting area 614, the limiting of the second connecting rod 20 can be achieved, so that the size and shape of the limiting area 614 can be set more flexibly.

[0160] Optionally, one of the first limiting portion 613 and the first limiting matching portion 208 includes a first limiting groove, and the other includes a first limiting column 209 . The first limiting column 209 is located in the first limiting groove and can move relative to the first limiting groove.

[0161] Through the cooperation between the first limiting groove and the first limiting column 209 , the motion range of the second connecting rod 20 can be limited more accurately, further improving the accuracy of motion control.

[0162] Optionally, one of the second limiting portion and the second limiting matching portion includes a second limiting groove, and the other includes a second limiting column, and the second limiting column is located in the second limiting groove and can move relative to the second limiting groove.

[0163] The second box cover guide portion 621 and / or the third box cover guide portion 625 can be used as the second limiting portion, that is, the second limiting portion includes the second box cover guide portion 621 and / or the third box cover guide portion 625, and accordingly, the second limiting portion includes the second box cover guide portion 621 and the second limiting matching portion includes the second connecting rod 20 guide portion and the third connecting rod guide portion, which can simplify the structure of the second box cover 62 and the second connecting rod 20.

[0164] For example, the second limiting column includes the second guide column 203 and / or the third guide column 205 , and the second limiting groove includes the second guide groove 622 and / or the third guide groove 626 .

[0165] Optionally, there are multiple second limiting grooves, the number of second limiting columns is equal to and corresponds to the number of second limiting grooves, and at least two second limiting grooves have different shapes.

[0166] During the movement of the second connecting rod 20 , when the second rotating shaft 502 moves along B2B3 , the movement trajectories of the plurality of second limiting posts are different. Therefore, correspondingly, the shapes of the plurality of second limiting grooves are different.

[0167] Alternatively, as Figure 7 As shown, the driving mechanism for the air guide plate further includes a third limiting portion 211 , and the third limiting portion 211 is supported between the first connecting rod 10 and the second connecting rod 20 .

[0168] The third limiting portion 211 is fixed to the first connecting rod 10 or the second connecting rod 20 and is made of wear-resistant material. The third limiting portion 211 is supported between the first connecting rod 10 and the second connecting rod 20 to avoid direct contact between the first connecting rod 10 and the second connecting rod 20, thereby reducing wear of the first connecting rod 10 and the second connecting rod 20.

[0169] The third limiting portion 211 may be one or more third limiting columns.

[0170] The first limiting column 209 and the second limiting column are also made of wear-resistant material to reduce wear.

[0171] The driving wheel 30 also includes a first driving part 303; the first connecting rod 10 also includes a first driving matching part 104, and the first driving part 303 and the first driving matching part 104 slide or roll to drive the first connecting rod 10 to move; wherein, in the process of the driving wheel 30 driving the first connecting rod 10 to move, the engagement of the first rack 101 and the first tooth part 301, and the cooperation of the first driving part 303 and the first driving matching part 104 occur in sequence, or the cooperation of the first driving part 303 and the first driving matching part 104, and the engagement of the first rack 101 and the first tooth part 301 occur in sequence.

[0172] As the driving wheel 30 rotates, the first tooth portion 301 first engages with the first rack 101 to drive the first connecting rod 10 to move, and then the first driving portion 303 and the first driving engagement portion 104 slide or roll to drive the first connecting rod 10 to move. Alternatively, the first driving portion 303 and the first driving engagement portion 104 first slide or roll to drive the first connecting rod 10 to move, and then the first tooth portion 301 engages with the first rack 101 to drive the first connecting rod 10 to move. The movement of the first connecting rod 10 drives the movement of the air deflector 70, thereby opening and closing the air deflector 70.

[0173] The cooperation between the first tooth portion 301 and the first rack 101 is more reliable and stable than the cooperation between the column and the groove, and reduces the wear of the cooperation between the column and the groove; and the meshing of the first rack 101 and the first tooth portion 301, and the cooperation between the first drive portion 303 and the first drive matching portion 104 occur in sequence, or the cooperation between the first drive portion 303 and the first drive matching portion 104, and the meshing of the first rack 101 and the first tooth portion 301 occur in sequence, which can conveniently change the motion parameters of the first connecting rod 10, such as the motion trajectory or motion speed, thereby realizing a variety of wind-guiding positions of the wind guide plate 70.

[0174] Alternatively, as Figure 8 and Figure 9 As shown, the driving wheel 30 includes a first surface 304 and a second surface 305 that are oppositely disposed. The first tooth portion 301 and the first driving portion 303 are both disposed on the first surface 304 .

[0175] On the one hand, a second tooth portion 302 can be provided on the second surface 305 so that the first connecting rod 10 and the second connecting rod 20 do not interfere with each other. On the other hand, this arrangement improves the integration of the driving wheel 30, so that the driving wheel 30 can realize multiple functions on one plane.

[0176] Optionally, the first tooth portion 301 extends along the circumference of the driving wheel 30 and is non-annular.

[0177] Since the first tooth portion 301 is not a ring extending along the circumference of the driving wheel 30, that is, the first tooth portion 301 does not occupy a circle of the circumference of the driving wheel 30, the first tooth portion 301 and the first rack 101 may be disengaged during the process of the driving wheel 30 rotating one circle, thereby realizing the switching from the engagement of the first tooth portion 301 and the first rack 101 to the engagement of the first driving portion 303 with the first driving matching portion 104.

[0178] Optionally, one of the first driving portion 303 and the first driving matching portion 104 includes a first driving column 105 , and the other includes a first driving slot 312 adapted to the first driving column 105 .

[0179] When the first driving portion 303 cooperates with the first driving matching portion 104, the first driving column 105 is located in the first driving groove 312 and can slide or roll relative to the first driving groove 312, thereby realizing the driving of the first driving matching portion 104 by the first driving portion 303, that is, realizing the driving wheel 30 drives the first connecting rod 10 to move.

[0180] Optionally, the first driving slot 312 has an open end 315 , and the open end 315 passes through the edge of the driving wheel 30 or the first connecting rod 10 , and the first driving column 105 is inserted into or removed from the first driving slot 312 through the open end 315 of the first driving slot 312 .

[0181] When the first drive column 105 is not engaged with the first drive slot 312, the first drive column 105 is located outside the first drive slot 312. When the first drive column 105 is engaged with the first drive slot 312, the first drive column 105 is inserted into the first drive slot 312 through the open end 315 of the first drive slot 312. When the first drive column 105 is no longer engaged with the first drive slot 312, the first drive column 105 is disengaged from the first drive slot 312 through the open end 315 of the first drive slot 312.

[0182] like Figure 8 As shown, the first driving slot 312 is provided on the driving wheel 30 , and the opening end 315 of the first driving slot 312 passes through the edge of the driving wheel 30 .

[0183] Optionally, when the first driving portion 303 includes the first driving slot 312 , the first driving slot 312 includes a first slot section 313 . The first slot section 313 is provided on the inner side of the first tooth portion 301 and extends along the circumferential direction of the driving wheel 30 .

[0184] The first groove section 313 is located on the inner side of the first tooth portion 301, meaning that the first groove section 313 is located between the first tooth portion 301 and the rotation center M of the drive wheel 30. Compared to the first groove section 313 extending radially along the drive wheel 30, the first groove section 313 in the present application extends circumferentially along the drive wheel 30. When the drive wheel 30 rotates through the same angle, the movement stroke of the first connecting rod 10 is reduced, thereby enabling the first connecting rod 10 to reciprocate in the second trajectory segment A2A3.

[0185] The first drive slot 312 also includes a second slot section 314. One end of the second slot section 314 forms an open end 315 of the first drive slot 312, and the other end of the second slot section 314 communicates with the first slot section 313. The second slot section 314 does not extend along the circumference of the drive wheel 30. Therefore, when the first drive post 105 engages with the second slot section 314, and the drive wheel 30 rotates through the same angle, the movement stroke of the first connecting rod 10 is greater than when the first drive post 105 engages with the first slot section 313.

[0186] Optionally, when the first driving column 105 cooperates with the second slot section 314 , the motion trajectory of the first rotating shaft 501 is located in the A1A2 section.

[0187] Optionally, the first rack 101 and the first driving engagement portion 104 are sequentially arranged along the length direction of the first connecting rod 10 .

[0188] In this way, when the first connecting rod 10 moves, the meshing of the first tooth portion 301 and the first rack 101 and the cooperation of the first driving portion 303 and the first driving matching portion 104 occur in sequence, or the cooperation of the first driving portion 303 and the first driving matching portion 104 and the meshing of the first tooth portion 301 and the first rack 101 occur in sequence.

[0189] Alternatively, as Figure 3 As shown, the first connecting rod 10 further includes a connecting rod 109 , which is protruded from the side of the first rack 101 facing the driving wheel 30 , and the first driving engagement portion 104 is provided on the connecting rod 109 so that the first driving portion 303 can be engaged with the first driving engagement portion 104 .

[0190] Optionally, when the first driving portion 303 and the first driving mating portion 104 switch from the non-mating state to the mating state, the first tooth portion 301 and the first rack 101 are in a meshing state.

[0191] When the first tooth portion 301 is engaged with the first rack 101 to the end but has not yet separated, the first drive column 105 enters the first drive groove 312. At this time, the first connecting rod 10 is constrained by the first tooth portion 301 and the first drive portion 303 at the same time. At this time, the constraint on the first drive matching portion 104 is equivalent to the constraint on the first rack 101. When the first rack 101 is disengaged from the first tooth portion 301, the first drive matching portion 104 is constrained by the first drive portion 303, so that the first connecting rod 10 runs according to the designed trajectory.

[0192] Optionally, there are multiple first drive parts 303, and the number of first drive matching parts 104 is equal to and corresponds to the number of first drive parts 303; multiple first drive parts 303 are matched with the corresponding first drive matching parts 104 in turn, and when the first first drive part 303 and the first drive matching part 104 switch from a non-matching state to a matching state, the first tooth part 301 and the first rack 101 are in a meshing state.

[0193] The multiple first driving parts 303 are respectively a first first driving part 303, a second first driving part 303, etc. When the first tooth portion 301 is still in meshing state with the first rack 101, the first first driving part 303 and the first driving matching part 104 have switched from a non-matching state to a matching state. Thus, before the first tooth portion 301 is disengaged from the first rack 101, at least one first driving part 303 is matched with the first driving matching part 104. At this time, the meshing of the first tooth portion 301 and the first rack 101 and the matching of the first driving part 303 and the first driving matching part 104 jointly drive the movement of the first connecting rod 10, achieving a smooth switching from the meshing of the first tooth portion 301 and the first rack 101 to the matching of the first driving part 303 and the first driving matching part 104.

[0194] When the air guide plate 70 is opened, the driving wheel 30 rotates, the second tooth portion 302 engages with the second rack 201 , and after the driving wheel 30 rotates to the set position, the first driving portion 303 cooperates with the first driving matching portion 104 .

[0195] After the drive wheel 30 rotates to the set position, the first drive portion 303 engages with the first drive engagement portion 104 to drive the first connecting rod 10, and the second tooth portion 302 engages with the second rack 201 to drive the second connecting rod 20. Compared to the related art, the use of the second tooth portion 302 to engage with the second rack 201 in the second connecting rod 20 reduces the number of posts and slots, thereby reducing wear on the second connecting rod 20 and the drive wheel 30. Furthermore, the first connecting rod 10 is driven by the cooperation of the first drive portion 303 and the first drive engagement portion 104, while the second connecting rod 20 is driven by the cooperation of the second tooth portion 302 and the second rack 201. This combination of multiple drive methods facilitates the flexible movement of the air deflector 70.

[0196] Alternatively, as Figure 7 As shown, the second rack 201 is a non-linear rack.

[0197] This arrangement enables the second connecting rod 20 to not be limited to linear motion, that is, the second connecting rod 20 can achieve a more complex motion trajectory during the movement process, meeting the diverse requirements of the air conditioner for the position and angle of the air guide plate 70 in different working modes.

[0198] Alternatively, as Figure 32 As shown, the second rack 201 includes a first tooth segment 206 and a second tooth segment 207 arranged in sequence along the length direction of the second connecting rod 20, the pitch line B4B5 of the first tooth segment 206 is arc-shaped, and the pitch line B5B6 of the second tooth segment 207 is non-arc-shaped. When the second tooth portion 302 is engaged with the second tooth segment 207, the first driving portion 303 cooperates with the first driving matching portion 104.

[0199] The pitch line B5B6 of the second tooth segment 207 is non-circular and its center of curvature is not fixed. When the second tooth portion 302 is engaged with the second tooth segment 207, the second connecting rod 20 does not perform translational motion but deflection motion. The wind deflector 70 moves under the joint drive of the first connecting rod 10 and the second connecting rod 20, so the motion trajectory of the first connecting rod 10 needs to match the motion trajectory of the second connecting rod 20. When the second connecting rod 20 performs deflection motion, the first connecting rod 10 cannot simply perform linear motion. Therefore, at this time, the first connecting rod 10 is driven by a gear rack, and the shape of the rack on the first connecting rod 10 will be more complex. In other words, when the second tooth portion 302 is engaged with the second tooth segment 207, the first connecting rod 10 uses the first drive portion 303 to cooperate with the first drive matching portion 104, which can more easily meet the requirements for the motion trajectory of the first connecting rod 10.

[0200] When the first driving part 303 cooperates with the first driving matching part 104, the first rotating shaft 501 has reciprocating motion. This can be understood as, when the first driving part 303 cooperates with the first driving matching part 104, the entire stroke of the first rotating shaft 501 is reciprocating motion, or only part of the stroke is reciprocating motion. The second rotating shaft 502 has a non-circular trajectory motion. This can be understood as, when the first driving part 303 cooperates with the first driving matching part 104, the entire stroke of the second rotating shaft 502 is along the non-circular trajectory, or only part of the stroke is along the non-circular trajectory.

[0201] During the process of opening the air guide plate 70 from the first position to the third position, the driving wheel 30 rotates unidirectionally and the first rotating shaft 501 reciprocates. When the driving wheel 30 rotates unidirectionally, it is difficult to achieve reciprocating motion by using a rack and pinion drive. Therefore, when the first driving part 303 is provided to cooperate with the first driving matching part 104, the first rotating shaft 501 reciprocates.

[0202] When the first driving part 303 cooperates with the first driving cooperation part 104, the first rotating shaft 501 has reciprocating motion, the second rotating shaft 502 has a non-circular arc trajectory motion, and the first connecting rod 10 and the second connecting rod 20 cooperate to meet the requirements for the wind guide position of the wind guide plate 70.

[0203] Optionally, the first rack 101 and the first drive mating portion 104 are arranged in sequence along the length direction of the first connecting rod 10. When the first drive portion 303 and the first drive mating portion 104 are not engaged, the first tooth portion 301 is engaged with the first rack 101, thereby enabling the first connecting rod 10 to move through the engagement of the first tooth portion 301 with the first rack 101.

[0204] When the first tooth portion 301 is not engaged with the first rack 101 , the first driving portion 303 cooperates with the first driving engagement portion 104 , thereby driving the first connecting rod 10 to move.

[0205] Alternatively, as Figure 3 and Figure 4 As shown, the first rack 101 is a non-linear rack.

[0206] This enables the first connecting rod 10 to achieve a more complex motion trajectory during movement, rather than being limited to linear motion, thereby meeting the diverse requirements of the air conditioner for the position and angle of the air guide plate 70 under different working modes.

[0207] Optionally, the driving wheel 30 includes a first surface 304 and a second surface 305 that are oppositely arranged. The first tooth portion 301 and the first driving portion 303 are both arranged on the first surface 304 , and the second tooth portion 302 is arranged on the second surface 305 .

[0208] The first tooth portion 301 and the first driving portion 303 drive the first connecting rod 10, and the second tooth portion 302 drives the second connecting rod 20. The first tooth portion 301 and the first driving portion 303 are both arranged on the first surface 304, and the second tooth portion 302 is arranged on the second surface 305, so that the positions of the first tooth portion 301 and the first driving portion 303 and the position of the second tooth portion 302 do not interfere with each other, thereby making the movements of the first connecting rod 10 and the second connecting rod 20 do not interfere with each other.

[0209] The rotation axis of the driving wheel 30 is arranged perpendicular to the first surface 304 and the second surface 305 .

[0210] The first link 10 is provided in the mechanism box 6 and moves relative to the mechanism box 6 between a retracted position for retracting the mechanism box 6 and an extended position for extending the mechanism box 6 .

[0211] like Figure 19 and Figure 30 As shown, one of the mechanism box 6 and the first connecting rod 10 is provided with a first positioning portion 110, and the other of the mechanism box 6 and the first connecting rod 10 is provided with a first positioning fitting portion 615 and a second positioning fitting portion 616. The first positioning fitting portion 615 and the second positioning fitting portion 616 are arranged in sequence along the direction from the first box cover 61 to the second box cover 62. The first positioning portion 110 is arranged between the first positioning fitting portion 615 and the second positioning fitting portion 616 to limit the movement of the first connecting rod 10 in the direction of the line connecting the first box cover 61 and the second box cover 62.

[0212] The first positioning and fitting portion 615 and the second positioning and fitting portion 616 are sequentially arranged along the direction from the first box cover 61 to the second box cover 62. The first positioning portion 110 is arranged between the first positioning and fitting portion 615 and the second positioning and fitting portion 616. The first positioning portion 110 cooperates with the first positioning and fitting portion 615 to limit the movement of the first connecting rod 10 toward the first box cover 61. The second positioning portion cooperates with the second positioning and fitting portion 616 to limit the movement of the second connecting rod 20 toward the second box cover 62, thereby limiting the movement of the first connecting rod 10 in the direction of the line connecting the first box cover 61 and the second box cover 62. Moreover, the position limiting of the first connecting rod 10 is not achieved by means of the second connecting rod 20, avoiding the interaction force between the first connecting rod 10 and the second connecting rod 20 as in the related art, thereby ensuring the movement accuracy of the air deflector 70.

[0213] Optionally, one of the mechanism box 6 and the first connecting rod 10 is provided with a positioning rib 111, and the other of the mechanism box 6 and the first connecting rod 10 is provided with a positioning groove 617, the positioning groove 617 includes a first groove wall 618 and a second groove wall 619, the first groove wall 618 and the second groove wall 619 are arranged opposite to each other and are arranged in sequence along the direction from the first box cover 61 to the second box cover 62, the positioning rib 111 is located between the first groove wall 618 and the second groove wall 619, wherein the first positioning portion 110 includes the positioning rib 111, the first positioning matching portion 615 includes the first groove wall 618, and the second positioning matching portion 616 includes the second groove wall 619.

[0214] The positioning rib 111 is arranged in the positioning groove 617 and is located between the first groove wall 618 and the second groove wall 619. The first groove wall 618 limits the direction of the positioning rib 111 toward the first groove wall 618, and the second groove wall 619 limits the direction of the positioning rib 111 toward the second groove wall 619. This limiting method has high reliability and low cost.

[0215] Optionally, one of the mechanism box 6 and the first connecting rod 10 with the positioning groove 617 is further provided with a positioning protrusion 621 , the positioning protrusion 621 is sleeved with a positioning wheel 622 , and the positioning groove 617 is provided on the positioning wheel 622 .

[0216] When the mechanism box 6 is provided with a positioning groove 617, the mechanism box 6 is also provided with a positioning protrusion 621; when the first connecting rod 10 is provided with a positioning groove 617, the first connecting rod 10 is also provided with a positioning protrusion 621. A positioning wheel 622 is sleeved on the outer side of the positioning protrusion 621. The positioning wheel 622 and the positioning protrusion 621 can be made of different materials. The positioning wheel 622 is made of a wear-resistant material to reduce wear of the positioning wheel 622. The positioning groove 617 is annular and extends along the circumference of the positioning wheel 622.

[0217] Optionally, the positioning rib 111 is made of a wear-resistant material to reduce wear of the positioning rib 111 .

[0218] like Figure 2 As shown, the first box cover 61 is provided with a positioning protrusion 621 , a positioning wheel 622 is sleeved on the outer side of the positioning protrusion 621 , and the first connecting rod 10 is provided with a positioning rib 111 .

[0219] Optionally, there are multiple positioning grooves 617 , and the multiple positioning grooves 617 are sequentially arranged along the direction from the retracted position to the extended position. During the movement of the first connecting rod 10 , the positioning rib 111 is located in at least one positioning groove 617 .

[0220] In this way, during the entire movement of the first connecting rod 10, there is always at least one positioning groove 617 cooperating with the positioning rib 111 to limit the movement of the first connecting rod 10 in the direction of the line connecting the first box cover 61 and the second box cover 62; and multiple positioning grooves 617 are provided, and only one positioning groove 617 is needed to cooperate with the positioning rib 111 at different times to limit the movement of the first connecting rod 10 in the direction of the line connecting the first box cover 61 and the second box cover 62. There is no need for the positioning rib 111 to cooperate with each positioning groove 617 throughout the movement of the first connecting rod 10, so that the length of the positioning rib 111 does not need to be too large, thereby reducing the size of the positioning rib 111.

[0221] Optionally, a guide slope 106 is provided at the end of the positioning rib 111 in the length direction to enable the positioning rib 111 to be inserted into or removed from the positioning groove 617 .

[0222] The provision of the guide slope 106 can guide the positioning rib 111 to be smoothly inserted into the positioning groove 617. The ends of the positioning rib 111 in the longitudinal direction include a first end 112 and a second end 113. The first end 112 and the second end 113 are arranged in sequence along the direction from the retracted position to the extended position, and the first end 112 and / or the second end 113 are provided with the guide slope 106. Along the direction from the retracted position to the extended position, the surface of the first end 112 facing the first groove wall 618 is inclined in a direction away from the middle portion of the first connecting rod 10 to form the guide slope 106, and the surface of the second end 113 facing the first groove wall 618 is inclined in a direction toward the middle portion of the first connecting rod 10 to form the guide slope 106.

[0223] There are two positioning grooves 617. When the air guide plate 70 is in the closed position, the positioning rib 111 only cooperates with the positioning groove 617 away from the air guide plate 70 among the two positioning grooves 617. As the air guide plate 70 moves, the positioning rib 111 cooperates with both positioning grooves 617. Then, as the air guide plate 70 moves, the positioning rib 111 only cooperates with the positioning groove 617 close to the air guide plate 70 among the two positioning grooves 617.

[0224] Alternatively, the first positioning portion 110 may be in the form of a positioning rib 111 , and the first positioning fitting portion 615 and the second positioning fitting portion 616 may both be in the form of a groove, and the positioning rib 111 may be inserted into the groove and slide relative to the groove.

[0225] Optionally, the other one of the mechanism box 6 and the first link 10 is provided with a support portion 620 , which is connected between the first positioning fitting portion 615 and the second positioning fitting portion 616 and is located below the first positioning portion 110 to support the first positioning portion 110 .

[0226] By providing the support portion 620 between the first positioning fitting portion 615 and the second positioning fitting portion 616 , additional support can be provided to the first positioning portion 110 , thereby preventing the first positioning portion 110 from moving downward, and further ensuring the stability of the first positioning portion 110 .

[0227] In a specific embodiment, Figure 30 As shown, the bottom wall surface of the positioning groove 617 forms a support portion 620 .

[0228] Optionally, the driving mechanism for the air guide plate also includes a second connecting rod 20, which is arranged in the mechanism box 6, and the first connecting rod 10 and the second connecting rod 20 are arranged in sequence along the direction from the first box cover 61 to the second box cover 62; when the first positioning portion 110 is arranged in the mechanism box 6, the first positioning portion 110 is arranged on the first box cover 61 and there is a gap between it and the second box cover 62, so as to avoid the setting of the first positioning portion 110 affecting the movement of the second connecting rod 20; when the first positioning matching portion 615 and the second positioning matching portion 616 are arranged in the mechanism box 6, the first positioning matching portion 615 and the second positioning matching portion 616 are both arranged on the first box cover 61 and there are gaps between the first positioning matching portion 615, the second positioning matching portion 616 and the second box cover 62, so as to avoid the setting of the first positioning matching portion 615 and the second positioning matching portion 616 affecting the movement of the second connecting rod 20.

[0229] The driving mechanism for the air deflector further includes a power source, which includes a driving wheel 30 .

[0230] like Figure 11 、 Figure 13 、 Figure 17 、 Figure 21 、 Figure 25 As shown, the mechanism box 6 is provided with a stroke limiting area 623; the first connecting rod 10 includes a driving matching structure 115 that cooperates with the first driving part 303, so that the power source drives the first connecting rod 10 to move, and the driving matching structure 115 is at least partially located in the stroke limiting area 623; wherein, during the movement of the first connecting rod 10, the driving matching structure 115 is at least partially located in the stroke limiting area 623 and moves relative to the stroke limiting area 623, so that the stroke limiting area 623 limits the movement area of the driving matching structure 115, so that the first connecting rod 10 moves between the first extreme position and the second extreme position, which can effectively prevent the first connecting rod 10 from being excessively offset during the movement, thereby accurately limiting the movement range and position of the air guide plate 70.

[0231] Optionally, the first connecting rod 10 is disposed between the power source and the first box cover 61, and the stroke limiting area 623 is disposed on the first box cover 61. On the one hand, the distance between the first connecting rod 10 and the stroke limiting area 623 is small, which facilitates the cooperation between the first connecting rod 10 and the stroke limiting area 623; on the other hand, the cooperation between the drive cooperation structure 115 and the stroke limiting area 623 does not affect the cooperation between the first driving part 303 and the power cooperation structure, that is, it does not affect the driving of the first connecting rod 10 by the power source.

[0232] Optionally, the surface of the mechanism box 6, such as the first box cover 61, is recessed toward the first connecting rod 10 to form a stroke limiting area 623. On the one hand, the recessed form ensures that the setting of the limiting area does not affect the setting of the drive matching structure 115. On the other hand, the strength of the first box cover 61 can also be enhanced.

[0233] Optionally, the first connecting rod 10 further includes a first rod body 114 including the first rack 101 ; the drive engagement structure 115 includes a first drive engagement portion 104 and a connecting rod 109 . The connecting rod 109 is connected between the first rod body 114 and the first drive engagement portion 104 .

[0234] During the movement of the first connecting rod 10 , the connecting rod 109 is located in the stroke limiting area 623 and moves relative to the stroke limiting area 623 , so that the stroke limiting area 623 defines the movement area of the driving engagement structure 115 .

[0235] The limiting effect of the stroke limiting area 623 on the drive matching structure 115 is achieved through the limiting effect of the stroke limiting area 623 on the connecting rod 109, rather than through the limiting effect of the stroke limiting area 623 on the first drive matching part 104, so that the limiting effect of the stroke limiting area 623 does not affect the matching between the first drive matching part 104 and the first drive part 303, and thus does not affect the drive of the first connecting rod 10 by the power source.

[0236] Optionally, the first box cover 61 , the connecting rod 109 and the first rod body 114 are arranged in sequence.

[0237] On the one hand, the connecting rod 109 is closer to the first box cover 61, and thus closer to the stroke limiting area 623, which facilitates the cooperation between the connecting rod 109 and the stroke limiting area 623; on the other hand, the first drive cooperation part 104 and the first rod body 114 are both arranged on the side of the connecting rod 109 away from the first box cover 61, so that the first drive cooperation part 104 and the first rack 101 are close to the driving wheel 30, which facilitates the cooperation between the driving wheel 30 and the first drive cooperation part 104 and the first rack 101.

[0241] The driving mating structure 115 includes a third limiting end 118, and the stroke limiting area 623 includes a third limiting side wall 626. When the first connecting rod 10 moves to the first extreme position, the third limiting end 118 abuts against the third limiting side wall 626 to limit the third limiting end 118 from continuing to move beyond the third limiting side wall 626, thereby limiting the first connecting rod 10 from continuing to move beyond the first extreme position.

[0242] The driving mating structure 115 includes a fourth limiting end 119, and the stroke limiting area 623 includes a fourth limiting side wall 627. When the first connecting rod 10 moves to the second limit position, the fourth limiting end 119 abuts against the fourth limiting side wall 627 to limit the fourth limiting end 119 from continuing to move beyond the fourth limiting side wall 627, thereby limiting the first connecting rod 10 from continuing to move beyond the second limit position.

[0243] The third limiting end 118 and the fourth limiting end 119 are disposed opposite each other, and the third limiting side wall 626 and the fourth limiting side wall 627 are disposed opposite each other. The third limiting side wall 626 is connected between one end of the first limiting side wall 624 and the second limiting side wall 625, and the fourth limiting side wall 627 is connected between the other ends of the first limiting side wall 624 and the second limiting side wall 625. The first limiting side wall 624, the second limiting side wall 625, the third limiting side wall 626, and the fourth limiting side wall 627 collectively enclose a travel limiting region 623 shaped like a rectangle.

[0244] The first surface 304 is provided with a first driving portion 303 for driving the first connecting rod 10 , and the second surface 305 is provided with a second tooth portion 302 for driving the second connecting rod 20 , wherein the first driving portion 303 includes a first driving slot 312 or a first driving column 105 .

The first drive portion 303 is provided on the first surface 304, and the second tooth portion 302 is provided on the second surface 305. In this way, the movements of the first connecting rod 10 and the second connecting rod 20 do not affect each other. In addition, the first drive portion 303 includes a first drive groove 312 or a first drive column 105, which is different from the second tooth portion 302 in the form of gear teeth. Through different forms, different movements of the first connecting rod 10 and the second connecting rod 20 can be achieved, thereby making it easier to achieve differential movement of the first connecting rod 10 and the second connecting rod 20. There is no need to switch the driving state of the drive wheel 30 on the first rack 101 and the second rack 201 (simultaneous drive or separate drive) as in the related art, thereby simplifying the structure and control logic.

[0246] Optionally, the second tooth portion 302 extends along the circumference of the driving wheel 30 and is annular or non-annular.

[0247] For example, when the second connecting rod 20 is driven by the second tooth portion 302 throughout its entire movement, the second tooth portion 302 is annular.

[0248] When the second connecting rod 20 is partially driven by the second tooth portion 302, the second tooth portion 302 is non-annular. In this case, the second surface 305 is provided with a second drive portion for driving the second connecting rod 20. The second drive portion includes a second drive groove or a second drive column. The second connecting rod 20 is provided with a second drive mating portion. The second drive portion and the second drive mating portion slide or roll in engagement. One of the second drive portion and the second drive mating portion is the second drive groove, and the other is the second drive column. The second drive mating portion and the second rack 201 are arranged sequentially along the length of the second connecting rod 20. During the opening process of the air deflector 70, the meshing of the second tooth portion 302 with the second rack 201 and the mating of the second drive portion and the second drive mating portion occur sequentially. Alternatively, the mating of the second drive portion and the second drive mating portion and the meshing of the second tooth portion 302 with the second rack 201 occur sequentially.

[0249] Optionally, when the first driving portion 303 is the first driving column 105 , the first driving column 105 protrudes from the first tooth portion 301 to facilitate the matching between the first driving column 105 and the first driving slot 312 .

[0250] Optionally, one of the first tooth portion 301 and the second tooth portion 302 is a cylindrical gear, and the other is a non-circular gear, and the axes of the first tooth portion 301 and the second tooth portion 302 coincide with each other.

[0251] Optionally, when the first driving portion 303 includes a first driving column 105 , there are multiple first driving columns 105 , wherein a central angle formed by a line connecting two first driving columns 105 and the rotation center of the first tooth portion 301 is greater than 90°.

[0252] On the one hand, a plurality of first drive posts 105 are provided, and the number of the first drive slots 312 is equal to the number of the first drive posts 105 and corresponds one to one to realize multi-point drive, thereby improving the driving ability of the drive wheel 30 and the movement accuracy of the first connecting rod 10; on the other hand, the central angle formed by the line connecting the two first drive posts 105 and the rotation center of the first tooth portion 301 is greater than 90°, that is, two first drive posts 105 among the plurality of first drive posts 105, for example, the first drive post 105E and the first drive post 105F, the central angle formed by the line connecting the first drive post 105E and the rotation center of the first tooth portion 301, and the central angle formed by the line connecting the first drive post 105F and the rotation center of the first tooth portion 301 is greater than 90°, that is, the first drive posts 105E and the first drive post 105F are far apart, thereby realizing smooth movement of the drive wheel 30, thereby realizing smooth driving of the first connecting rod 10.

[0253] The second surface 305 is provided with a second driving portion for driving the second connecting rod 20 . The second driving portion includes a second driving groove or a second driving column.

[0254] The second connecting rod 20 is provided with a second drive engaging portion that slides or rolls with the second drive engaging portion. One of the second drive engaging portion and the second drive engaging portion includes a second drive post, and the other includes a second drive slot. During the movement of the second connecting rod 20, a portion of the travel is driven by the engagement of the second tooth portion 302 with the second rack 201, while another portion of the travel is driven by the engagement of the second drive engaging portion and the second drive engaging portion. The provision of the second drive engaging portion and the second drive engaging portion can alter the motion trajectory of the second connecting rod 20, thereby reducing the travel of the second connecting rod 20.

[0255] Optionally, the driving wheel 30 includes a driving body 306, a first power unit is provided on the first side of the driving body 306, and a second power unit is provided on the second side, the first side and the second side are arranged opposite to each other, the first side is the side where the first surface 304 is located, and the second side is the side where the second surface 305 is located; the first connecting rod 10 is provided on the first side of the driving body 306 and is driven and connected to the first power unit, and the first connecting rod 10 is driven and connected to the wind guide plate 70; the second connecting rod 20 is provided on the second side of the driving body 306 and is driven and connected to the second power unit, and the second connecting rod 20 is driven and connected to the wind guide plate 70; wherein, the driving body 306 is used to separate between the first connecting rod 10 and the second connecting rod 20.

[0256] like Figure 8 、 Figure 9 、 Figure 15 and Figure 16 As shown, the driving body 306 is used to separate the first connecting rod 10 and the second connecting rod 20, which can prevent the first connecting rod 10 from hitting the second power unit and the second connecting rod 20 from hitting the first power unit, thereby ensuring the movement accuracy of the first power unit and the second power unit. In other words, the driving body 306 can limit the movement of the first connecting rod 10 toward the second power unit and can also limit the movement of the second connecting rod 20 toward the first power unit, that is, limit the movement of the first connecting rod 10 and the second connecting rod 20 in the direction of the line connecting the first connecting rod 10 and the second connecting rod 20 (along the thickness direction of the mechanism box 6).

[0257] Optionally, the driving body 306 includes a wheel body 310 and a partition plate 311. The first power unit and the second power unit are both provided on the wheel body 310; the partition plate 311 is provided on the wheel body 310. When the air deflector 70 is at least partially opened, the partition plate 311 is provided between the first connecting rod 10 and the second connecting rod 20 to separate the first connecting rod 10 from the second connecting rod 20.

[0258] The partition plate 311 is used to separate the first connecting rod 10 and the second connecting rod 20, which can prevent the first connecting rod 10 from hitting the second power unit and also prevent the second connecting rod 20 from hitting the first power unit, thereby ensuring the movement accuracy of the first and second power units.

[0259] Optionally, the partition plate 311 is provided at the outer edge of the wheel body 310 and extends radially outwardly of the wheel body 310 , so that the arrangement of the partition plate 311 does not affect the arrangement of the first power unit and the second power unit.

[0260] Optionally, a first avoidance groove 120 for accommodating the partition plate 311 is provided on the surface of the first connecting rod 10 facing the driving body 306, so that when the partition plate 311 is arranged between the first connecting rod 10 and the second connecting rod 20, the partition plate 311 is located in the first avoidance groove 120 to avoid interference between the partition plate 311 and the first connecting rod 10; and / or a second avoidance groove 212 for accommodating the partition plate 311 is provided on the surface of the second connecting rod 20 facing the driving body 306, so that when the partition plate 311 is arranged between the first connecting rod 10 and the second connecting rod 20, the partition plate 311 is located in the second avoidance groove 212 to avoid interference between the partition plate 311 and the second connecting rod 20.

[0261] Optionally, the first power unit includes a first tooth portion 301, the first connecting rod 10 includes a first rack 101 for engaging with the first tooth portion 301, and the partition plate 311 is arranged corresponding to the first tooth portion 301, so that when the first tooth portion 301 engages with the first rack 101, the partition plate 311 is arranged between the first connecting rod 10 and the second connecting rod 20.

[0262] During the engagement of the first tooth portion 301 with the first rack 101 , the partition plate 311 is provided between the first connecting rod 10 and the second connecting rod 20 , that is, the partition plate 311 is used to limit the first connecting rod 10 and the second connecting rod 20 along the thickness direction of the mechanism box 6 .

[0263] Optionally, the first power unit includes a first driving unit 303, and the first connecting rod 10 includes a driving engagement structure 115 that is driven and engaged with the first driving unit 303, and the driving engagement structure 115 includes a first driving engagement portion 104 and a connecting rod 109. The first driving unit 303 slides or rolls with the driving engagement structure 115; the driving body 306 also includes a partition wall that protrudes radially outward along the wheel body 310. When the first driving unit 303 engages with the driving engagement structure 115, the partition wall is located between the driving engagement structure 115 and the second connecting rod 20 to separate the driving engagement structure 115 and the second connecting rod 20, that is, to separate the first connecting rod 10 and the second connecting rod 20, thereby limiting the movement of the first connecting rod 10 and the second connecting rod 20 in the thickness direction of the mechanism box 6.

[0264] When the first driving portion 303 is engaged with the drive engagement structure 115, the engagement between the first driving portion 303 and the drive engagement structure 115 can limit the movement of the first connecting rod 10 toward the second connecting rod 20, thereby eliminating the need for a partition wall. Furthermore, the partition plate 311 is staggered with the drive engagement structure 115. That is, when the first driving portion 303 is engaged with the drive engagement structure 115, the partition plate 311 is not positioned between the first connecting rod 10 and the second connecting rod 20. In other words, the partition plate 311 does not serve to limit the position of the first connecting rod 10 and the second connecting rod 20 along the thickness direction of the mechanism box 6.

[0265] Optionally, the first power unit includes a first driving unit 303, and the first connecting rod 10 includes a driving cooperation structure 115 that is driven and cooperated with the first driving unit 303, and the first driving unit 303 slides or rolls with the driving cooperation structure 115; the driving cooperation structure 115 is provided with a third avoidance groove 121, and when the first driving unit 303 cooperates with the driving cooperation structure 115, the driving body 306 is at least partially located in the third avoidance groove 121, so as to avoid interference between the driving body 306 and the first connecting rod 10.

[0266] Optionally, the radius of the second tooth portion 302 is smaller than the radius of the driving body 306 , so that the partition plate 311 is located outside the second tooth portion 302 , wherein the direction away from the rotation center of the driving wheel 30 is outside.

[0267] An embodiment of the second aspect of the present invention provides an air conditioner, including an indoor unit 80, the indoor unit 80 including a shell, an indoor heat exchanger, a fan, an air guide plate 70 and a driving mechanism for the air guide plate as described in any of the above embodiments, the first connecting rod 10 is directly rotationally connected to the air guide plate 70 through a first rotating shaft 501, and the second connecting rod 20 is directly rotationally connected to the air guide plate 70 through a second rotating shaft 502.

[0268] The housing defines an air duct, which includes an air inlet and an air outlet 404. The indoor heat exchanger and fan are both located within the duct. Driven by the fan, air enters the duct through the air inlet, exchanges heat with the indoor heat exchanger, and then flows out of the air outlet 404. An air deflector 70 is located at the air outlet 404 to adjust the opening and closing of the air outlet 404 and the direction of air flow.

[0269] The air conditioner provided in the embodiment of the second aspect of the present invention includes a driving mechanism for an air guide plate as described in any one of the above embodiments, and thus has all the beneficial effects of the driving mechanism for an air guide plate as described in any one of the above embodiments, which will not be repeated here.

[0270] like Figure 29 As shown, the housing includes a panel 403, and the indoor unit 80 also includes a cover 405. Cover 405 is located inside panel 403. Panel 403 is provided with an air outlet 404, and cover 405 is provided with an opening 406. The mechanism box 6, opening 406, and air deflector 70 are arranged in this order. When air deflector 70 is opened, the first connecting rod 10 and the second connecting rod 20 extend through opening 406.

[0271] The air guide plate 70 includes a plate body 701 for opening or closing the air outlet 404. The connecting portion 702 is protruded from a side of the plate body 701 facing the housing 405. When the air guide plate 70 is in the first position, the connecting portion 702 is located in the opening 406.

[0272] The first connecting rod 10 is directly rotatably connected to the connecting part 702 through the first rotating shaft 501. For example, the first connecting rod 10 is provided with a first axial hole 122, the connecting part 702 is provided with a second axial hole, and the first rotating shaft 501 is rotatably provided in the first axial hole 122 and the second axial hole, or, the first connecting rod 10 is provided with a first axial hole 122, the first rotating shaft 501 is provided in the connecting part 702, the first rotating shaft 501 passes through the first axial hole 122 and is rotatably connected to the first axial hole 122.

[0273] The second connecting rod 20 is directly rotatably connected to the connecting portion 702 via the second rotating shaft 502. For example, the second connecting rod 20 is provided with a third shaft hole 213, the connecting portion 702 is provided with a fourth shaft hole, and the second rotating shaft 502 is rotatably disposed in the third shaft hole 213 and the fourth shaft hole. Alternatively, the second connecting rod 20 is provided with a third shaft hole 213, the second rotating shaft 502 is provided in the connecting portion 702, and the second rotating shaft 502 passes through the third shaft hole 213 and is rotatably connected to the third shaft hole 213.

[0274] like Figure 33 As shown, in the process of the air guide plate 70 opening from the first position to the second position, when the first rotating shaft 501 passes through the opening 406, the width direction of the connecting portion 702 (such as Figure 33 The second rotating shaft 502 does not exceed the edge of the connecting portion 702 in the width direction when in the first position (as shown by the direction of the arrow in the middle), and / or, when the second rotating shaft 502 passes through the opening 406, the second rotating shaft 502 does not exceed the edge of the connecting portion 702 in the width direction when in the first position.

[0275] During the process of opening the air guide plate 70 from the first position to the second position, when the first rotating shaft 501 passes through the opening 406, the first rotating shaft 501 in the first position does not exceed the edge of the connecting portion 702 in the width direction of the connecting portion 702 in the first position, or the orthographic projection of the first rotating shaft 501 on the connecting portion 702 in the first position does not exceed the edge of the connecting portion 702 in the width direction of the connecting portion 702 in the first position, so as to limit the movement range of the first rotating shaft 501 when passing through the opening 406, thereby limiting the movement range of the entire first connecting rod 10, thereby reducing the cover 4 05, and / or, when the second rotating shaft 502 passes through the opening 406, the second rotating shaft 502 does not exceed the edge of the connecting portion 702 in the width direction when the second rotating shaft 502 is in the first position, or the positive projection of the second rotating shaft 502 on the connecting portion 702 when the second rotating shaft 502 is in the first position does not exceed the edge of the connecting portion 702 in the width direction when the second rotating shaft 502 is in the first position, so as to limit the movement range of the second rotating shaft 502 when passing through the opening 406, thereby limiting the movement range of the entire second connecting rod 20, thereby reducing the opening 406 of the cover 405.

[0276] The edges of the connecting portion 702 in the width direction include a first edge 703 and a second edge 704 that are relatively arranged. When the first rotating shaft 501 passes through the opening 406, the first rotating shaft 501 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position. In this way, when the first connecting rod 10 passes through the opening 406, the first connecting rod 10 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position, thereby limiting the size of the opening 406 and preventing the opening 406 from being too large. When the second rotating shaft 502 passes through the opening 406, the second rotating shaft 502 does not exceed the edge of the connecting portion 702 in the width direction when it is in the second position. In this way, when the second connecting rod 20 passes through the opening 406, the second connecting rod 20 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position, thereby limiting the size of the opening 406 and preventing the opening 406 from being too large.

[0277] The second connecting rod 20 includes a second guide post 203 and a third guide post 205. Figure 33 In the embodiment, the motion trajectory of the second guide post is B8, B81, B82, and the motion trajectory of the third guide post is B9, B91, or B10, B101. When the air deflector opens from the first position to the second position, the motion trajectory of the second guide post is B8, B81. When the air deflector opens from the second position to the third position, the motion trajectory of the second guide post is B81, B82. The mechanism box 6 is provided with a second guide slot 622 and a third guide slot 626. The second guide post 203 is disposed within the second guide slot 622 and is movable relative to the second guide slot 622. The third guide post 205 is disposed within the third guide slot 626 and is movable relative to the third guide slot 626, thereby guiding the motion trajectory of the second connecting rod 20.

[0278] The second guide column 203 is arranged between the third guide column 205 and the second rotating shaft 502. In the process of opening the air guide plate 70 from the second position to the third position, the third guide column 205 and the second rotating shaft 502 have reverse movement, and under the constraint of the second guide groove 622, the second guide column 203 moves along the length direction of the second guide groove 622. This can be understood as the second connecting rod 20 rotating around the second guide column 203. The second connecting rod 20 can be imagined as a lever, and the second guide column 203 serves as the fulcrum of the lever. At the same time, the second guide column 203 moves in the second guide groove 622. The second guide column 203 does not move relative to the second connecting rod 20, and the second connecting rod 20 is driven to rotate around the second guide column 203 by the third guide column 205.

[0279] Optionally, when the air guide plate 70 opens from the second position to the third position, the second guide column 203 does not exceed the edge of the connecting portion 702 in the width direction when the second guide column 203 is in the first position.

[0280] The second guide column 203 serves as the rotation center of the second connecting rod 20, and while satisfying the motion trajectory of the second rotating axis 502 being B2B3, the second connecting rod 20 entity is always located between the first edge 703 and the second edge 704 in the width direction of the connecting part 702 when the opening 406 is in the first position, thereby reducing the size of the opening 406.

[0281] Optionally, during the process of the air guide plate 70 opening from the second position to the third position, when the first rotating shaft 501 passes through the opening 406, the first rotating shaft 501 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position. In this way, when the first connecting rod 10 passes through the opening 406, the first connecting rod 10 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position, thereby limiting the size of the opening 406 and preventing the opening 406 from being too large.
