[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 otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0060] Combination Figure 1-30 , Figure 35 As shown, this embodiment of the present disclosure provides a drive assembly for an air conditioning deflector, including a drive wheel 30, a first link 10, and a second link 20.

[0061] like Figures 3 to 8 As shown, the drive wheel 30 is rotated in a controlled manner and includes a first tooth 301 and a second tooth 302; the first connecting rod 10 includes a first rack 101 for meshing with the first tooth 301 and is directly rotatably connected to the air guide plate 70 through a first rotating shaft 501; the second connecting rod 20 includes a second rack 201 for meshing with the second tooth 302 and is directly rotatably connected to the air guide plate 70 through a second rotating shaft 502.

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

[0063] The first connecting rod 10 is a one-piece structure, directly rotatably connected to the air guide plate 70 via the first rotating shaft 501. No other connecting rods 109 connect the first connecting rod 10 to the air guide plate 70. The second connecting rod 20 is also a one-piece structure, directly rotatably connected to the air guide plate 70 via the second rotating shaft 502. No other connecting rods 109 connect the second connecting rod 20 to the air guide plate 70. Furthermore, both the first connecting rod 10 and the second connecting rod 20 are rotatably connected to the air guide plate 70, rather than slidingly connected, thus avoiding wear on the first connecting rod 10 and the second connecting rod 20 during sliding.

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

[0065] The rotation axes of the first tooth 301 and the second tooth 302 coincide and rotate synchronously. The angular velocities of the two are the same, which simplifies the control of the movement process of the first link 10 and the second link 20. On the other hand, the first tooth 301 and the second tooth 302 can be driven by a motor 407.

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

[0067] This configuration allows the first link 10 and the second link 20 to have different speeds and trajectories during movement, thereby enabling 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 the user's comfort.

[0069] Optionally, the drive assembly for the air conditioning deflector also includes a reduction gear 40, which is connected between the motor 407 and the drive wheel 30. The motor 407 is driven by the reduction gear 40, which meshes with a cylindrical gear. The cylindrical gear is fixedly connected to a non-circular gear. The motor 407 drives the reduction gear 40 to rotate, which in turn drives the cylindrical gear to rotate, 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 302.

[0071] Optionally, such as Figure 32 As shown, during the opening of the air guide plate 70, the movement trajectory of the first rotating shaft 501 includes a first trajectory segment A1A2 and a second trajectory segment A2A3, and the movement trajectory of the second rotating shaft 502 includes a third trajectory segment B1B2 and a 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, during the movement of the air guide plate 70, when the first rotating shaft 501 moves along A2A3, the second rotating shaft 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 arc curve, which causes the first link 10 and / or the second link 20 to deflect during the movement, so that the air guide plate 70 can achieve complex movement modes and better adapt to the shape of the air conditioning outlet 404 and the air guiding requirements.

[0072] Optionally, both the first trajectory segment A1A2 and the third trajectory segment B1B2 are circular arcs.

[0073] This configuration simplifies the movement trajectory of the first link 10 and the second link 20, making the control logic of the drive assembly for the air conditioning deflector simpler, facilitating precise motion control, improving the reliability and stability of the system, and making the movement of the deflector 70 smoother in the initial opening phase, reducing vibration and noise during the movement.

[0074] Optionally, the second trajectory segment A2A3 is an arc shape, and it is two arcs on the same circle as the first trajectory segment A1A2. The two arcs share a common point A2. This setting makes the movement of the first rotating shaft 501 more continuous and avoids abrupt changes and stuttering when moving from the first trajectory segment to the second trajectory 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] A fourth position may exist between the first and second positions, and a fifth position may exist between the second and third positions. During the opening process, the air guide plate 70 passes through the first, fourth, second, fifth, and third positions sequentially. For example... Figures 1 to 30 As shown, the first position is the off position, the fourth position is the cooling horizontal airflow position, the second position is the maximum airflow position, the fifth position is the wraparound airflow position, and the third position is the heating downward airflow position. Alternatively, the fourth position is the heating downward airflow position, and the third position is the cooling horizontal airflow position.

[0077] When the air guide plate 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 with the traditional unidirectional movement trajectory, the reciprocating motion avoids the first connecting rod 10 from over-extending during its movement, thereby reducing the installation space requirement of the drive assembly for the air conditioning air guide plate inside the indoor unit 80.

[0078] Optionally, such as Figure 32 As shown, the fourth trajectory segment B2B3 is a non-circular arc curve. In conjunction with the reciprocating motion of the first rotating shaft 501 along the second trajectory segment A2A3, it moves from A2 to A3 and then from A3 to A2, performing 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 rotating shaft 502 moves along the fourth trajectory segment B2B3, the second rotating shaft 502 rotates on its own axis and revolves around the first rotating shaft 501.

[0080] During the movement of the air guide plate 70 from the second position to the third position, the rotation center of the second rotating shaft 502 is the position of the first rotating shaft 501 corresponding to the current position of the second rotating shaft 502. Specifically, at the same moment, when the second rotating shaft 502 is at position B7, the first rotating shaft 501 is at position A7. Here, B7 is a point between B2 and B3 in the second trajectory segment B2B3, and A7 is a point between A2 and A3 in the second trajectory segment A2A3. The position of the first rotating shaft 501 is not fixed during the movement of the air guide plate 70; therefore, the position of the rotation center of the second rotating shaft 502 is also not fixed. Combined with the rotation of the second rotating shaft 502, the air guide plate 70 flips from the second position to the third position.

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

[0082] Optionally, when the second rotating shaft 502 moves along the fourth trajectory segment B2B3, the motion trajectories of different points on the second link 20 located on the same plane are different, wherein the plane is the longitudinal section of the second link 20.

[0083] This configuration allows the second link 20 to perform planar motion, that is, to move within the plane containing the longitudinal section of the second link 20. Since the velocities and trajectories of different points on the second link 20 located on the same plane are different when the second rotation shaft 502 moves along the fourth trajectory segment B2B3, the second link 20 does not perform translational motion, but rather a combination of movement and rotation, with the instantaneous rotation centers of the points on the same plane constantly changing. This, combined with the movement of the first rotation shaft 501, enables the air guide plate 70 to move from the second position to the third position.

[0084] Optionally, such as Figure 12 and Figure 16 As shown, the second link 20 includes a second link guide 202 and a third link guide 204. During the opening of the air guide plate 70, the second link guide 202 has a reciprocating motion, 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 204 moves in one direction.

[0085] The third link guide 204 moves in one direction, while the second link guide 202 moves in a reciprocating motion. Through the reciprocating motion of the second link guide 202 and the one-way motion of the third link guide 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, meeting the diverse needs of the air conditioner for air guiding direction and angle under different operating conditions.

[0086] Optionally, the second link guide 202 is located between the third link guide 204 and the second rotating shaft 502. The movement trajectory of the second link 20 is realized by the movement trajectory of the second rotating shaft 502, the movement trajectory of the second link guide 202, and the movement trajectory of the third link guide 204, so as to meet the movement requirements of the air guide plate 70.

[0087] Optionally, during the process of the air guide plate 70 opening from the first position to the second position, both the second link guide 202 and the third link guide 204 move in one direction.

[0088] During the process of the air guide plate 70 opening from the first position (closed position) to the second position (maximum air supply position), both the second link guide 202 and the third link guide 204 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] Optionally, such as Figures 1 to 18 As shown, during 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 part 202 and the third link guide part 204 are the same. The same movement trajectory means that the movement trajectory can completely overlap after translation, which makes the movement of the air guide plate 70 more stable and consistent, avoids shaking and jamming during the movement, and improves the uniformity and reliability of air guidance.

[0090] Optionally, such as Figures 18 to 30 As shown, during the process of the air guide plate 70 opening from the second position to the third position, the third link guide part 204 and the second rotating shaft 502 have opposite movements or opposite movement trends, or there is a moment when the angle between the movement direction of the third link guide part 204 and the second rotating shaft 502 is greater than 90°, so that the second link 20 can be deflected at a large angle instead of translated, thereby enabling the air guide plate 70 to flip when the stroke of the second link 20 is small, so that the air guide plate 70 can switch from the second position to the third position.

[0091] Optionally, during the process of the air guide plate 70 opening from the second position to the third position, the movement trajectories of the second link guide 202 and the third link guide 204 are different, so that the second link 20 can deflect instead of translate, 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 assembly for the air conditioning deflector also includes a mechanism box 6. The mechanism box 6 includes a first cover 61 and a second cover 62 that are arranged opposite to each other and joined together. The first cover 61 and the second cover 62 together define an accommodating space. The first connecting rod 10, the second connecting rod 20, the drive wheel 30, and the reduction wheel 40 are all located within the accommodating space. The first connecting rod 10 and the second connecting rod 20 are arranged sequentially along the direction from the first cover 61 to the second cover 62.

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

[0094] The second cover 62 also includes a third cover guide 625, which cooperates with the third link guide 204, and the second cover guide 621 cooperates with the second link guide 202 to jointly guide the movement trajectory of the second link 20.

[0095] like Figure 14 As shown, one of the second cover guide portion 621 and the second link guide portion 202 is a second guide groove 622, and the other is a second guide post 203. The second guide post 203 is adapted to the second guide groove 622, and the second guide post 203 is located in the second guide groove 622 and can slide relative to the second guide groove 622. One of the third cover guide portion 625 and the third link guide portion 204 is a third guide groove 626, and the other is a third guide post 205. The third guide post 205 is adapted to the third guide groove 626, and the third guide post 205 is located in the third guide groove 626 and can slide relative to the third guide groove 626.

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

[0097] The second guide groove 622 includes a first sub-guide groove 623 and a second sub-guide groove 624 that are sequentially arranged and connected along the length 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 post 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 that are sequentially arranged and connected along the length 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 post 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, during 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. The second guide post 203 is located in the first sub-guide groove 623 and can slide unidirectionally relative to the first sub-guide groove 623. The third guide post 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 post 203 cooperates with the first sub-guide groove 623, and the third guide post 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 have the same shape 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, during 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. The second guide post 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. The third guide post 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 post 203 cooperates with the second sub-guide groove 624, and the third guide post 205 cooperates with the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence. When the third guide post 205 cooperates with the fourth sub-guide groove 628, the third guide post 205 and the second rotating shaft 502 have opposite movements. When the third guide post 205 cooperates with the low-speed sub-guide groove, the third guide post 205 and the second rotating shaft 502 have the same direction of 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 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 302. The pitch line B5B6 of the second tooth segment 207 is a non-circular curve, so that the rotation center of the second connecting rod 20 is not a fixed point during the meshing of the second tooth 302 and the second tooth segment 207. During the meshing of the second tooth 302 and the second tooth segment 207, the air guide plate 70 moves from the second position to the third position, and the corresponding motion trajectory of the second rotating shaft 502 is a non-circular trajectory B2B3.

[0101] The second tooth segment, with its 207-pitch line, employs a non-circular curve, enabling the air guide plate 70 to achieve complex motion trajectories in various positions. This design overcomes the limitations of traditional circular arc gear transmissions, making the movement of the air guide plate 70 more flexible and diverse, better adapting to the needs of the air conditioner in different operating modes.

[0102] The pitch line design of the second tooth segment 207 means that the second link 20 does not have a fixed center of rotation during movement. This dynamic center of rotation design enables more complex motion modes. For example, during the opening of the air guide plate 70, the second link 20 can be adjusted in multiple directions as needed to achieve a more ideal air delivery effect.

[0103] Optionally, the pitch line of the second tooth segment 207 satisfies the following: when the second tooth 302 meshes with the second tooth segment 207, the velocities and angular velocities of the points 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 air guiding positions of the air guide plate 70.

[0104] Optionally, the pitch line of the second tooth segment 207 satisfies the following: when the second tooth 302 meshes with the second tooth segment 207, the motion trajectories of each point 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 air guiding positions of the air guide plate 70.

[0105] Optionally, the second link 20 also includes a second link guide 202 and a third link guide 204. The pitch line of the second tooth segment 207 satisfies the following: when the second tooth 302 meshes with the second tooth segment 207, during the opening of the air guide plate 70, the second link guide 202 has reciprocating motion, and the third link guide 204 has unidirectional motion.

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

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

[0108] When the second tooth 302 meshes with the first tooth segment 206, the movement trajectory of the second rotating shaft 502 is an arc-shaped trajectory B1B2.

[0109] During the opening of the air guide plate 70, the second tooth 302 engages sequentially with the first tooth segment 206 and the second tooth segment 207. During the engagement of the second tooth 302 with the first tooth segment 206, the air guide plate 70 moves from the first position to the second position.

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

[0111] The first cover 61 is provided with a first cover guide 611, and the first connecting rod 10 is provided with a first connecting rod guide 102. One of the first connecting rod guide 102 and the first cover guide 611 is a first guide groove 612, and the other is a first guide post 103. The first guide post 103 is adapted to the first guide groove 612. The first guide post 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 rotating shaft 501 moves along the first trajectory segment A1A2, the first guide post 103 moves unidirectionally within the first guide groove 612. When the first rotating shaft 501 reciprocates along the second trajectory segment A2A3, the first guide post 103 reciprocates within the first guide groove 612. The number of first guide posts 103 can be one or more, and the number of first guide grooves 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 each first guide groove 612. When multiple first guide posts 103 are provided within the first guide groove 612, the multiple first guide posts 103 are sequentially arranged along the length direction of the first guide groove 612.

[0113] The first link 10 can perform translational motion. The motion trajectories of all points on the first link 10 are 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 link 10 may not undergo translational motion, or it may deflect during the motion.

[0115] like Figure 32 As shown, with the air guide plate 70 in the closed position, the first rotating shaft 501 is located at point A1, and the second rotating shaft 502 is located at point B1. A1A2 and A2A3 are both arc-shaped, with the center of the arc at A0. B1B2 are also arc-shaped, with the center at B0. The rotation center (or center of the circle) of the pitch line B4B5 of the first tooth segment 206 is B0. Figure 31 As shown, the pitch line of the second tooth 302 is circle B7, the pitch line of the first tooth 301 is 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 curves A4A6 and A4A5 are tangent at point A4. The curve combination B4B5B6 is tangent to the initial position of circle B7 (when the air guide plate 70 is in the closed position) at point B4; then, in the segment of pitch line B4B5, that is, during the entire process of the second tooth 302 meshing with the first tooth segment 206, the position of the tangent point remains unchanged at B4. In the segment of pitch line B5B6, that is, during the process of the second tooth 302 meshing with the second tooth segment 207, the tangent point moves along curve B5B6.

[0116] The pitch line B5B6 is a curve, not a circular arc, and has no fixed center. Its shape is a curve or spline curve that is tangent to all points on it. During the meshing process between the second tooth 302 and 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 changes continuously.

[0117] Nodal lines A4A5 and A4A6, although curved in shape, are not circular arcs and have no fixed center, but they have fixed centers of rotation, namely A0 and E respectively.

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

[0119] This application achieves the extension and rotation of the air guide plate 70 by using the different displacement differences between the first rotating shaft 501 and the second rotating shaft 502.

[0120] Air guide plate 70 changes from closed position to cooling flat-blowing position to maximum airflow 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 302 meshes with the first tooth segment 206; that is, the first rotating shaft 501 rotates around A0, the second rotating shaft 502 rotates around B0, and the distance between the first rotating shaft 501 and the second rotating shaft 502 remains unchanged during the movement.

[0122] The air guide plate 70 extends from the maximum air supply position to the wraparound air supply position and then to the heating down-blowing position.

[0123] The first rotating shaft 501 starts from A2 and moves back and forth on the arc A2A3, finally moving to A2; the second tooth 302 meshes with the second tooth segment 207, and the second rotating shaft 502 starts from B2 and moves along the curve B2B3 to B3, where the curve B2B3 is not a circular arc, and its instantaneous rotation center, the first rotating shaft 501, moves back and forth on the arc A2A3, finally moving to A2.

[0124] Optionally, during the movement of the air guide plate 70, the transmission ratio i of the first toothed section 301 and the first rack 101 is related to the angular velocity ω of the first rotating shaft 501. A Angular velocity ω of the second rotating axis 502 B There are constraints.

[0125] During the movement of the air guide plate 70, the length of the line connecting the first rotating shaft 501 and the second rotating shaft 502 remains constant. This ensures that when the first rotating shaft 501 and the second rotating shaft 502 move along their respective trajectories, the speeds of the first rotating shaft 501 and the second rotating shaft 502 must satisfy a certain functional relationship. In other words, during the movement of the air guide plate 70, the transmission ratio i of the first tooth 301 and the first rack 101 is related to the angular velocity ω of the first rotating shaft 501. A Angular velocity ω of the second rotating axis 502 B The existence of constraints allows the first link 10 and the air guide plate 70 to be directly rotatably connected via the first rotating shaft 501, and the second link 20 and the air guide plate 70 to be directly rotatably connected via the second rotating shaft 502.

[0126] If the first connecting rod 10 is provided with a sliding column and the air guide plate 70 is provided with a sliding groove, the sliding column is located in the sliding groove and is slidably connected to the sliding groove, and the second connecting rod 20 is directly rotatably connected to the air guide plate 70 through the second rotating shaft 502, and is slidably connected to the air guide plate 70 through the cooperation of the sliding column and the sliding groove, the distance between the sliding column and the second rotating column changes during the movement of the air guide plate 70. Therefore, 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 guide plate, the transmission ratio i of the first tooth and the first rack is related to the angular velocity ω of the first rotating shaft. A angular velocity ω of the second rotation axis B There are constraints.

[0128] During the movement of the air guide plate, the length of the line connecting the first and second rotating shafts remains constant. This ensures that when the first and second rotating shafts move along their respective trajectories, their velocities must satisfy a certain functional relationship. In other words, during the movement of the air guide plate, the transmission ratio i of the first tooth and the first rack is related to the angular velocity ω of the first rotating shaft. A angular velocity ω of the second rotation axis B The existence of constraints allows the first link to be directly rotatably connected to the air guide plate via the first rotating shaft, and the second link to be directly rotatably connected to the air guide plate via 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 slidably connected to the sliding groove. The second connecting rod is directly rotatably connected to the air guide plate through the second rotating shaft. It is slidably 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. Therefore, the requirement for the relationship between the movement speed of the first rotating shaft and the movement speed of the second rotating shaft is not as strict as in this application.

[0130] Establish a coordinate system with B0 as the 0 point and the B0A0 direction as the X-axis. 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 about B0 is ω. B The angular velocity of the first rotation axis about A0 is ω A The angular velocity of C is ω C ω C This can be understood as the angular velocity of the line connecting the first and second rotation axes rotating about the second rotation axis, i.e., the rate of change of C, which can be obtained from the principle of linkage mechanism:

[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; differentiating equations ① and ② with respect to time T, 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 obtain

[0137]

[0138] Let m = L4*sinB - L2*sinA, n = L1 + L2*cosA - L4*cosB, simplifying equation ⑤, we can obtain the ratio of the angular velocities of the second rotation axis to the first rotation axis, that is:

[0139]

[0140] To simplify the design, a fixed transmission ratio (i.e., uniform speed transmission) is selected for the second tooth and the second rack that drive the second rotating shaft. Therefore, the pitch line radius of the first tooth and the first rack that drive the first rotating shaft can be solved according to equation ⑥. Based on the structural position design method, the position of the center E of the second tooth 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] Let the angular velocity of the drive wheel be ω1, the radius of A4A6 be r1, the radius of A4A5 be r2, and the initial angle of A be θ1, i.e., when the guide vane is in the closed position, A = θ1. The center distance A0E = a, then...

[0142]

[0143] By combining equations ⑦ and ⑧, the transmission ratio i between the first tooth section and the first rack can be obtained.

[0144]

[0145] The equation of nodal line A4A6 is:

[0146]

[0147] The equation of nodal line A4A5 is:

[0148]

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

[0150] Combined ⑤, ⑥, ⑨, ⑩ The formula is imported into mathematical calculation software, a calculation program is written, and the pitch line A4A6 and pitch line A4A5 graphics are drawn. The pitch line graphics are then imported into 3D drawing software, and the tooth profile is drawn according to the tooth profile design method (such as the method disclosed in application number CN202310777054.8).

[0151] The above transmission ratio applies to the stage where the second rotating shaft moves along B1B2.

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

[0153] like Figure 1 , Figure 2 and Figure 7As shown, the first lid 61 is provided with a first limiting part 613, and the second lid 62 is provided with a second limiting part; the second link 20 is provided with a first limiting engagement part 208 that cooperates with the first limiting part 613 and a second limiting engagement part that cooperates with the second limiting part, so as to restrict the movement of the second link 20 in the direction of the line connecting the first lid 61 and the second lid 62.

[0154] The first lid 61 and the second lid 62 are arranged opposite to each other. The first limiting part 613 and the first limiting mating part 208 of the first lid 61 can restrict the movement of the second link 20 toward the first lid 61. The second limiting part and the second limiting mating part of the second lid 62 can restrict the movement of the second link 20 toward the second lid 62. This achieves accurate limiting of the second link 20 in the direction of the line connecting the first lid 61 and the second lid 62. Moreover, the limiting of the second link 20 is not achieved by means of the first link 10, thus avoiding the second link 20 affecting the movement of the first link 10.

[0155] Optionally, the first limiting part 613 includes a limiting area 614 formed by the first cover 61 protruding toward the second link 20, which reduces the distance between the limiting area 614 and the second link 20, thereby facilitating the contact and engagement between the first limiting part 613 and the first limiting mating part 208. Moreover, the limiting area 614 can also enhance the strength of the first cover 61. The first limiting mating part 208 includes a first limiting post 209 provided on the second link 20. The first limiting post 209 abuts against the limiting area 614 and can move relative to the limiting area 614.

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

[0157] During the opening of the air guide plate 70, the second link 20 moves, and the first limiting engagement part 208 moves with the second link 20. Therefore, the size of the limiting area 614 needs to ensure that the limiting area 614 can always contact the first limiting engagement part 208 throughout the entire stroke of the first limiting engagement part 208.

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

[0159] Optionally, there are multiple first limiting posts 209. During the movement of the second link 20, at least one of the multiple first limiting posts 209 abuts against the limiting area 614. On the one hand, when multiple first limiting posts 209 are in contact with the limiting area 614, the limiting effect on the second link 20 can be enhanced. On the other hand, by setting multiple first limiting posts 209, as long as one first limiting post 209 is in contact with the limiting area 614, the second link 20 can be limited, thereby allowing for more flexible setting of the size and shape of the limiting area 614.

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

[0161] The cooperation of the first limiting groove and the first limiting post 209 can more accurately limit the range of motion of the second link 20, further improving the accuracy of motion control.

[0162] Optionally, one of the second limiting part and the second limiting mating part includes a second limiting groove, and the other includes a second limiting post, the second limiting post being located in the second limiting groove and being able to move relative to the second limiting groove.

[0163] The second lid guide 621 and / or the third lid guide 625 can be used as the second limiting part, that is, the second limiting part includes the second lid guide 621 and / or the third lid guide 625. Correspondingly, the second limiting part includes the second lid guide 621, and the second limiting mating part includes the second link 20 guide part and the third link guide part. This simplifies the structure of the second lid 62 and the second link 20.

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

[0165] Optionally, there may be multiple second limiting grooves, and the number of second limiting posts may be equal to the number of second limiting grooves and correspond one-to-one, with at least two second limiting grooves having different shapes.

[0166] During the movement of the second link 20, when the second rotating shaft 502 moves along B2B3, the movement trajectories of the multiple second limiting posts are different. Therefore, the corresponding shapes of the multiple second limiting grooves are different.

[0167] Optionally, such as Figure 7 As shown, the drive assembly for the air conditioning deflector also includes a third limiting part 211, which is supported between the first link 10 and the second link 20.

[0168] The third limiting part 211 is fixedly disposed on the first link 10 or the second link 20 and is made of wear-resistant material. The third limiting part 211 is supported between the first link 10 and the second link 20 to avoid direct contact between the first link 10 and the second link 20, thereby reducing the wear of the first link 10 and the second link 20.

[0169] The third limiting part 211 can be one or more third limiting posts.

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

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

[0172] As the drive wheel 30 rotates, the first tooth 301 meshes with the first rack 101, driving the first connecting rod 10 to move. Then, the first drive part 303 slides or rolls with the first drive mating part 104, driving the first connecting rod 10 to move. Alternatively, the first drive part 303 slides or rolls with the first drive mating part 104, driving the first connecting rod 10 to move, and then the first tooth 301 meshes with the first rack 101, driving the first connecting rod 10 to move. The movement of the first connecting rod 10 drives the air guide plate 70 to move, thus opening and closing the air guide plate 70.

[0173] The engagement between the first tooth 301 and the first rack 101 is more reliable and stable than the engagement between the column and the slot, and reduces wear associated with the column and slot engagement. Moreover, the sequential engagement of the first rack 101 and the first tooth 301, and the sequential engagement of the first drive part 303 and the first drive engagement part 104, or the sequential engagement of the first drive part 303 and the first drive engagement part 104, and the sequential engagement of the first rack 101 and the first tooth 301, allows for easy modification of the motion parameters of the first connecting rod 10, such as the motion trajectory or the motion speed, thereby enabling various air guiding positions of the air guide plate 70.

[0174] Optionally, such as Figure 8 and Figure 9 As shown, the drive wheel 30 includes a first surface 304 and a second surface 305 disposed opposite to each other, and the first tooth 301 and the first drive part 303 are both disposed on the first surface 304.

[0175] On the one hand, a second tooth 302 can be provided on the second surface 305, so that the first link 10 and the second link 20 can not interfere with each other. On the other hand, this arrangement improves the integration of the drive wheel 30, enabling the drive wheel 30 to perform multiple functions on a single plane.

[0176] Optionally, the first tooth 301 extends circumferentially along the drive wheel 30 and is non-circular.

[0177] Since the first tooth 301 is not a ring extending circumferentially along the drive wheel 30, that is, the first tooth 301 does not occupy one circumference of the drive wheel 30, there will be a situation where the first tooth 301 disengages from the first rack 101 during one rotation of the drive wheel 30, thereby realizing the switching from the engagement of the first tooth 301 and the first rack 101 to the engagement of the first drive part 303 and the first drive mating part 104.

[0178] Optionally, one of the first drive unit 303 and the first drive mating unit 104 includes a first drive post 105, and the other includes a first drive groove 312 adapted to the first drive post 105.

[0179] When the first drive unit 303 engages with the first drive engagement unit 104, the first drive column 105 is located in the first drive groove 312 and can slide or roll relative to the first drive groove 312, thereby realizing the drive of the first drive unit 303 on the first drive engagement unit 104, that is, realizing the drive wheel 30 driving the first connecting rod 10 to move.

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

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

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

[0183] Optionally, if the first drive unit 303 includes a first drive groove 312, the first drive groove 312 includes a first groove segment 313, which is disposed inside the first tooth 301 and extends circumferentially along the drive wheel 30.

[0184] The first groove segment 313 is located inside the first tooth portion 301, meaning that the first groove segment 313 is located between the first tooth portion 301 and the rotation center M of the drive wheel 30. Compared to the first groove segment 313 extending radially along the drive wheel 30, in this application, the first groove segment 313 extends circumferentially along the drive wheel 30. When the drive wheel 30 rotates through the same angle, the travel of the first connecting rod 10 can be reduced, thereby realizing the reciprocating motion of the first connecting rod 10 in the second trajectory segment A2A3.

[0185] The first drive groove 312 also includes a second groove segment 314. One end of the second groove segment 314 forms the opening end 315 of the first drive groove 312, and the other end of the second groove segment 314 is connected to the first groove segment 313. The second groove segment 314 does not extend along the circumference of the drive wheel 30. Therefore, when the first drive column 105 and the second groove segment 314 are engaged, the travel distance of the first connecting rod 10 is greater than the travel distance of the first connecting rod 10 when the first drive column 105 and the first groove segment 313 are engaged.

[0186] Optionally, when the first drive column 105 engages with the second groove segment 314, the motion trajectory of the first rotating shaft 501 is located in segment A1A2.

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

[0188] When the first link 10 moves, the engagement of the first tooth 301 with the first rack 101 and the engagement of the first drive part 303 with the first drive engagement part 104 occur sequentially, or the engagement of the first drive part 303 with the first drive engagement part 104 and the engagement of the first tooth 301 with the first rack 101 occur sequentially.

[0189] Optionally, such as Figure 3 As shown, the first connecting rod 10 also includes a connecting rod 109, which protrudes from the first rack 101 on the side facing the drive wheel 30. The first drive engagement part 104 is provided on the connecting rod 109 so that the first drive part 303 and the first drive engagement part 104 can cooperate.

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

[0191] When the first tooth 301 engages with the first rack 101 to the end but has not yet disengaged, the first drive column 105 enters the first drive groove 312. At this time, the first connecting rod 10 is simultaneously constrained by the first tooth 301 and the first drive part 303. The constraint on the first drive engagement part 104 is equivalent to the constraint on the first rack 101. When the first rack 101 disengages from the first tooth 301, the first drive engagement part 104 is constrained by the first drive part 303, causing the first connecting rod 10 to run along the designed trajectory.

[0192] Optionally, there are multiple first drive units 303, and the number of first drive mating units 104 is equal to the number of first drive units 303 and corresponds one-to-one; multiple first drive units 303 sequentially engage with corresponding first drive mating units 104, and when the first first drive unit 303 and the first drive mating unit 104 switch from a non-mating state to a mating state, the first tooth 301 and the first rack 101 are in a meshing state.

[0193] The multiple first drive units 303 are designated as the first first drive unit 303, the second first drive unit 303, and so on. When the first tooth 301 is still engaged with the first rack 101, the first first drive unit 303 and the first drive engagement unit 104 have switched from a non-engaged state to an engaged state. Thus, before the first tooth 301 disengages from the first rack 101, at least one first drive unit 303 has engaged with the first drive engagement unit 104. At this time, the engagement of the first tooth 301 with the first rack 101 and the engagement of the first drive unit 303 with the first drive engagement unit 104 together drive the first connecting rod 10 to move, achieving a smooth transition from the engagement of the first tooth 301 with the first rack 101 to the engagement of the first drive unit 303 with the first drive engagement unit 104.

[0194] During the opening of the air guide plate 70, the drive wheel 30 rotates, the second tooth 302 meshes with the second rack 201, and after the drive wheel 30 rotates to the set position, the first drive part 303 and the first drive engagement part 104 engage.

[0195] After the drive wheel 30 rotates to the set position, the first drive part 303 engages with the first drive mating part 104 to drive the first connecting rod 10 to move, and the second tooth part 302 meshes with the second rack 201 to drive the second connecting rod 20 to move. Compared with related technologies, since the second connecting rod 20 uses the second tooth part 302 to mesh with the second rack 201, the number of posts and slots is reduced, and the wear of the second connecting rod 20 and the drive wheel 30 is reduced. Moreover, the first connecting rod 10 is driven by the engagement of the first drive part 303 and the first drive mating part 104, and the second connecting rod 20 is driven by the engagement of the second tooth part 302 and the second rack 201. This combination of multiple drive methods facilitates the flexible movement of the air guide plate 70.

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

[0197] This configuration allows the second link 20 to move beyond linear motion, enabling it to achieve more complex trajectories during operation and meet the diverse needs of the air conditioner for the position and angle of the air guide plate 70 in different operating modes.

[0198] Optionally, such as Figure 32 As shown, the second rack 201 includes a first tooth segment 206 and a second tooth segment 207 arranged sequentially 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 302 is engaged with the second tooth segment 207, the first drive part 303 engages with the first drive mating part 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 302 meshes with the second tooth segment 207, the second connecting rod 20 does not perform translational motion but deflection motion. The air guide plate 70 moves under the joint drive of the first connecting rod 10 and the second connecting rod 20. Therefore, 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 deflects, the first connecting rod 10 cannot simply perform linear motion. Therefore, the first connecting rod 10 is driven by a gear and rack, and the shape of the rack on the first connecting rod 10 will be more complex. In other words, when the second tooth 302 meshes with the second tooth segment 207, the first connecting rod 10 uses the first driving part 303 and the first driving mating part 104 to cooperate, which can more easily meet the requirements of the motion trajectory of the first connecting rod 10.

[0200] When the first drive unit 303 engages with the first drive engagement unit 104, the first rotating shaft 501 reciprocates. This can be understood as the first rotating shaft 501 reciprocating throughout its entire stroke, or only partially. The second rotating shaft 502 moves along a non-circular trajectory. This can be understood as the second rotating shaft 502 moving along a non-circular trajectory throughout its entire stroke, or only partially.

[0201] During the process of the air guide plate 70 opening from the first position to the third position, the drive wheel 30 rotates in one direction, and the first rotating shaft 501 has reciprocating motion. When the drive wheel 30 rotates in one direction, it is difficult to achieve reciprocating motion by using a gear and rack drive. Therefore, when the first drive part 303 is set to cooperate with the first drive mating part 104, the first rotating shaft 501 has reciprocating motion.

[0202] When the first drive unit 303 cooperates with the first drive mating unit 104, the first rotating shaft 501 has reciprocating motion, and the second rotating shaft 502 has non-circular trajectory motion. The first connecting rod 10 and the second connecting rod 20 cooperate to meet the requirements of the air guiding position of the air guide plate 70.

[0203] Optionally, the first rack 101 and the first drive engagement part 104 are arranged sequentially along the length direction of the first connecting rod 10. When the first drive part 303 and the first drive engagement part 104 are not engaged, the first tooth 301 meshes with the first rack 101, thereby driving the first connecting rod 10 to move through the meshing of the first tooth 301 and the first rack 101.

[0204] When the first tooth 301 is not engaged with the first rack 101, the first drive part 303 engages with the first drive engagement part 104, thereby enabling the first connecting rod 10 to move through the engagement of the first drive part 303 and the first drive engagement part 104.

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

[0206] This allows the first link 10 to achieve more complex motion trajectories during movement, rather than being limited to linear motion, thereby meeting the diverse needs of the air conditioner for the position and angle of the air guide plate 70 in different working modes.

[0207] Optionally, the drive wheel 30 includes a first surface 304 and a second surface 305 disposed opposite to each other, a first tooth 301 and a first drive part 303 are both disposed on the first surface 304, and a second tooth 302 is disposed on the second surface 305.

[0208] The first tooth 301 and the first drive part 303 drive the first connecting rod 10, and the second tooth 302 drives the second connecting rod 20. The first tooth 301 and the first drive part 303 are both provided on the first surface 304, and the second tooth 302 is provided on the second surface 305, so that the positions of the first tooth 301 and the first drive part 303 and the second tooth 302 do not interfere with each other, thereby ensuring that 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 drive wheel 30 is set perpendicular to the first surface 304 and the second surface 305.

[0210] The first link 10 is located inside the mechanism box 6 and moves relative to the mechanism box 6 between the retracted position of the retracted mechanism box 6 and the extended position of the extended 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 part 110, and the other of the mechanism box 6 and the first connecting rod 10 is provided with a first positioning mating part 615 and a second positioning mating part 616. The first positioning mating part 615 and the second positioning mating part 616 are arranged sequentially along the direction from the first box cover 61 to the second box cover 62. The first positioning part 110 is provided between the first positioning mating part 615 and the second positioning mating part 616 to restrict 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 mating part 615 and the second positioning mating part 616 are arranged sequentially along the direction from the first cover 61 to the second cover 62. The first positioning part 110 is located between the first positioning mating part 615 and the second positioning mating part 616. The engagement of the first positioning part 110 with the first positioning mating part 615 restricts the movement of the first connecting rod 10 toward the first cover 61. The engagement of the second positioning part with the second positioning mating part 616 restricts the movement of the second connecting rod 20 toward the second cover 62, thereby restricting the movement of the first connecting rod 10 in the direction of the line connecting the first cover 61 and the second cover 62. Moreover, the 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 related technologies, thereby ensuring the movement accuracy of the air guide plate 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 sequentially 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. The first positioning part 110 includes the positioning rib 111, the first positioning mating part 615 includes the first groove wall 618, and the second positioning mating part 616 includes the second groove wall 619.

[0214] The positioning rib 111 is located in the positioning groove 617 and between the first groove wall 618 and the second groove wall 619. The first groove wall 618 restricts the positioning rib 111 to face the first groove wall 618, and the second groove wall 619 restricts the positioning rib 111 to face the second groove wall 619. This limiting method has high reliability and low cost.

[0215] Optionally, one of the positioning grooves 617 in the mechanism box 6 and the first connecting rod 10 is also provided with a positioning protrusion 621, and a positioning wheel 622 is fitted onto the positioning protrusion 621, with the positioning groove 617 located on the positioning wheel 622.

[0216] When the mechanism box 6 has a positioning groove 617, the mechanism box 6 also has a positioning protrusion 621; when the first connecting rod 10 has a positioning groove 617, the first connecting rod 10 also has a positioning protrusion 621. A positioning wheel 622 is fitted onto the outside 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. The positioning groove 617 is annular, extending circumferentially along the positioning wheel 622.

[0217] Optionally, the positioning rib 111 is made of a wear-resistant material to reduce wear on 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 outside of the positioning protrusion 621, and the first connecting rod 10 is provided with a positioning rib 111.

[0219] Optionally, there are multiple positioning slots 617, which are arranged sequentially 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 slot 617.

[0220] In this way, throughout the entire movement of the first link 10, at least one positioning groove 617 always engages with the positioning rib 111 to limit the movement of the first link 10 in the direction of the line connecting the first cover 61 and the second cover 62. Moreover, with multiple positioning grooves 617, only one positioning groove 617 needs to engage with the positioning rib 111 at different times to limit the movement of the first link 10 in the direction of the line connecting the first cover 61 and the second cover 62. It is not necessary for the positioning rib 111 to engage with every positioning groove 617 throughout the entire movement of the first link 10, so 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, the end of the positioning rib 111 in the length direction is provided with a guide slope 106 so that the positioning rib 111 can be inserted into or removed from the positioning groove 617.

[0222] The guide slope 106 guides the positioning rib 111 to smoothly insert into the positioning groove 617. The positioning rib 111 has a first end 112 and a second end 113 along its length. The first end 112 and the second end 113 are sequentially arranged 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 away from the middle 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 towards the middle of the first connecting rod 10 to form the guide slope 106.

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

[0224] Alternatively, the first positioning part 110 may adopt a positioning rib 111, and the first positioning mating part 615 and the second positioning mating part 616 may both adopt the form of a groove, with the positioning rib 111 inserted into the groove and sliding relative to the groove.

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

[0226] By providing a support portion 620 between the first positioning mating portion 615 and the second positioning mating portion 616, additional support can be provided to the first positioning portion 110 to prevent the first positioning portion 110 from moving downward and further ensure the stability of the first positioning portion 110.

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

[0228] Optionally, the drive assembly for the air conditioning deflector also includes a second link 20, which is disposed inside the mechanism box 6, and the first link 10 and the second link 20 are arranged sequentially along the direction from the first box cover 61 to the second box cover 62. When the first positioning part 110 is disposed in the mechanism box 6, there is a gap between the first positioning part 110 and the second box cover 62 to prevent the placement of the first positioning part 110 from affecting the movement of the second link 20. When the first positioning mating part 615 and the second positioning mating part 616 are disposed in the mechanism box 6, both the first positioning mating part 615 and the second positioning mating part 616 are disposed in the first box cover 61, and there are gaps between the first positioning mating part 615, the second positioning mating part 616 and the second box cover 62 to prevent the placement of the first positioning mating part 615 and the second positioning mating part 616 from affecting the movement of the second link 20.

[0229] The drive assembly for the air conditioning deflector also includes a power source, which includes drive wheels 30.

[0230] like Figure 11 , Figure 13 , Figure 17 , Figure 21 , Figure 25 As shown, the mechanism box 6 is provided with a stroke restriction area 623; the first link 10 includes a drive engagement structure 115 that cooperates with the first drive unit 303, so that the power source drives the first link 10 to move, and the drive engagement structure 115 is at least partially located within the stroke restriction area 623; wherein, during the movement of the first link 10, the drive engagement structure 115 is at least partially located within the stroke restriction area 623 and moves relative to the stroke restriction area 623, so that the stroke restriction area 623 limits the movement area of ​​the drive engagement structure 115, so that the first link 10 moves between the first limit position and the second limit position, which can effectively prevent the first link 10 from excessively deviating during the movement, thereby accurately limiting the movement range and position of the air guide plate 70.

[0231] Optionally, the first link 10 is located between the power source and the first cover 61, and the travel limiting region 623 is located on the first cover 61. On the one hand, the distance between the first link 10 and the travel limiting region 623 is small, which facilitates the cooperation between the first link 10 and the travel limiting region 623; on the other hand, the cooperation between the drive cooperation structure 115 and the travel limiting region 623 will not affect the cooperation between the first drive unit 303 and the power cooperation structure, that is, it will not affect the drive of the power source on the first link 10.

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

[0233] Optionally, the first link 10 further includes a first link body 114, which includes a first rack 101; the drive engagement structure 115 includes a first drive engagement part 104 and a connecting rod 109. The connecting rod 109 connects the first link body 114 and the first drive engagement part 104.

[0234] During the movement of the first link 10, the connecting rod 109 is located within the travel restriction area 623 and moves relative to the travel restriction area 623, so that the travel restriction area 623 limits the movement area of ​​the drive engagement structure 115.

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

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

[0237] On the one hand, the connecting rod 109 is closer to the first cover 61, and thus closer to the travel restriction area 623, which facilitates the engagement of the connecting rod 109 with the travel restriction area 623. On the other hand, the first drive engagement part 104 and the first rod body 114 are both located on the side of the connecting rod 109 away from the first cover 61, which makes the first drive engagement part 104 and the first rack 101 closer to the drive wheel 30, which facilitates the engagement of the drive wheel 30 with the first drive engagement part 104 and the first rack 101.

[0238] Optionally, the drive engagement structure 115 includes a first limiting end 116, and the stroke limiting region 623 includes a first limiting sidewall 624. During the movement of the first link 10, the first limiting end 116 and the first limiting sidewall 624 are always in contact and can move relative to the first limiting sidewall 624 to limit the movement of the first limiting end 116 across the first limiting sidewall 624 toward a direction away from the first limiting sidewall 624.

[0239] The drive engagement structure 115 also includes a second limiting end 117 disposed opposite to the first limiting end 116. The stroke restriction area 623 includes a second limiting sidewall 625 disposed opposite to the first limiting sidewall 624. During the movement of the first link 10, the second limiting end 117 and the second limiting sidewall 625 are always in contact and can move relative to the second limiting sidewall 625 to restrict the movement of the second limiting end 117 across the second limiting sidewall 625 toward a direction away from the second limiting sidewall 625.

[0240] During the movement of the first link 10, the first limiting end 116 abuts against the first limiting sidewall 624 and can move relative to the first limiting sidewall 624, and the second limiting end 117 abuts against the second limiting sidewall 625 and can move relative to the second limiting sidewall 625. The first limiting end 116 and the second limiting end 117 are arranged opposite to each other, and the first limiting sidewall 624 and the second limiting sidewall 625 are arranged opposite to each other. Thus, the first limiting sidewall 624 and the second limiting sidewall 625 can restrict the movement of the drive engagement structure 115 in the direction of the line connecting the first limiting sidewall 624 and the second limiting sidewall 625, thereby limiting the first link 10.

[0241] The drive engagement structure 115 includes a third limiting end 118, and the stroke limiting region 623 includes a third limiting sidewall 626. When the first link 10 moves to the first limit position, the third limiting end 118 abuts against the third limiting sidewall 626 to limit the third limiting end 118 from moving beyond the third limiting sidewall 626, thereby limiting the first link 10 from moving beyond the first limit position.

[0242] The drive engagement structure 115 includes a fourth limiting end 119, and the stroke limiting region 623 includes a fourth limiting sidewall 627. When the first link 10 moves to the second limit position, the fourth limiting end 119 abuts against the fourth limiting sidewall 627 to limit the fourth limiting end 119 from moving beyond the fourth limiting sidewall 627, thereby limiting the first link 10 from moving beyond the second limit position.

[0243] The third limiting end 118 and the fourth limiting end 119 are disposed opposite to each other, and the third limiting sidewall 626 and the fourth limiting sidewall 627 are disposed opposite to each other. The third limiting sidewall 626 is connected between one end of the first limiting sidewall 624 and the second limiting sidewall 625, and the fourth limiting sidewall 627 is connected between the other ends of the first limiting sidewall 624 and the second limiting sidewall 625. The first limiting sidewall 624, the second limiting sidewall 625, the third limiting sidewall 626 and the fourth limiting sidewall 627 together enclose a travel restriction area 623 with a shape similar to a rectangle.

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

[0245] The first drive unit 303 engages with the first connecting rod 10, and the second toothed part 302 engages with the second connecting rod 20. The first drive unit 303 is located on the first surface 304, and the second toothed part 302 is located 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. Moreover, the first drive unit 303 includes a first drive groove 312 or a first drive column 105, which is different from the toothed part 302. 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 realize the differential movement of the first connecting rod 10 and the second connecting rod 20. It eliminates the need to switch the driving state of the drive wheel 30 on the first rack 101 and the second rack 201 (simultaneous driving or separate driving) as required in related technologies, simplifying the structure and control logic.

[0246] Optionally, the second tooth 302 extends circumferentially along the drive wheel 30 and is either annular or non-annular.

[0247] For example, when the second link 20 is driven by the second tooth 302 throughout its entire movement, the second tooth 302 is in a ring shape.

[0248] When the second link 20 is partially driven by the second tooth 302, the second tooth 302 is non-circular. In this case, the second surface 305 is provided with a second driving part for driving the second link 20. The second driving part includes a second driving groove or a second driving post. The second link 20 is provided with a second driving engagement part. The second driving part and the second driving engagement part slide or roll together. One of the second driving part and the second driving engagement part is a second driving groove, and the other is a second driving post. The second driving engagement part and the second rack 201 are arranged sequentially along the length of the second link 20. During the opening of the air guide plate 70, the meshing of the second tooth 302 and the second rack 201, and the engagement of the second driving part and the second driving engagement part occur sequentially, or the engagement of the second driving part and the second driving engagement part, and the meshing of the second tooth 302 and the second rack 201 occur sequentially.

[0249] Optionally, when the first driving part 303 is the first driving post 105, the first driving post 105 protrudes from the first tooth part 301 to facilitate the engagement of the first driving post 105 with the first driving groove 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.

[0251] Optionally, when the first drive unit 303 includes a first drive post 105, the number of first drive posts 105 is multiple, wherein the central angle formed by the line connecting two first drive posts 105 and the rotation center of the first toothed part 301 is greater than 90°.

[0252] On the one hand, multiple first drive columns 105 are set, and the number of first drive grooves 312 is equal to the number of first drive columns 105 and corresponds one-to-one, realizing multi-point drive and improving the driving capability of drive wheel 30 and motion accuracy of first link 10. On the other hand, the central angle formed by the line connecting the rotation center of two first drive columns 105 and the first tooth 301 is greater than 90°. That is, two of the multiple first drive columns 105, such as first drive column 105E and first drive column 105F, form a central angle greater than 90° between the line connecting first drive column 105E and the rotation center of first tooth 301 and the line connecting first drive column 105F and the rotation center of first tooth 301. In other words, the distance between first drive columns 105E and first drive column 105F is relatively far, realizing the smooth movement of drive wheel 30, thereby realizing the smooth drive of first link 10.

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

[0254] The second link 20 is provided with a second drive engagement part. The second drive part and the second drive engagement part are in sliding or rolling engagement. One of the second drive part and the second drive engagement part includes a second drive post, and the other includes a second drive groove. During the movement of the second link 20, part of the stroke is driven by the meshing of the second tooth 302 and the second rack 201, and the other part of the stroke is driven by the engagement of the second drive part and the second drive engagement part. By providing the second drive part and the second drive engagement part, the movement trajectory of the second link 20 can be changed, thereby reducing the movement stroke of the second link 20.

[0255] Optionally, the drive wheel 30 includes a drive body 306. A first power unit is provided on a first side of the drive body 306, and a second power unit is provided on a 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. A first connecting rod 10 is provided on the first side of the drive body 306 and is drivenly connected to the first power unit. The first connecting rod 10 is drivenly connected to the air guide plate 70. A second connecting rod 20 is provided on the second side of the drive body 306 and is drivenly connected to the second power unit. The second connecting rod 20 is drivenly connected to the air guide plate 70. The drive body 306 is used to separate 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 drive body 306 is used to separate the first link 10 and the second link 20, preventing the first link 10 from contacting the second power unit and also preventing the second link 20 from contacting the first power unit, thereby ensuring the motion accuracy of the first and second power units. In other words, the drive body 306 can restrict the movement of the first link 10 toward the second power unit and also restrict the movement of the second link 20 toward the first power unit, that is, restrict the movement of the first link 10 and the second link 20 in the direction of the line connecting the first link 10 and the second link 20 (along the thickness direction of the mechanism box 6).

[0257] Optionally, the drive unit 306 includes a wheel body 310 and a partition plate 311. The first power unit and the second power unit are both disposed on the wheel body 310; the partition plate 311 is disposed on the wheel body 310, and during at least a part of the opening of the air guide plate 70, the partition plate 311 is disposed between the first link 10 and the second link 20 to separate the first link 10 and the second link 20.

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

[0259] Optionally, the partition plate 311 is disposed on the outer edge of the wheel body 310 and extends outward along the radial direction 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, the surface of the first link 10 facing the drive body 306 is provided with a first clearance groove 120 for accommodating the partition plate 311. When the partition plate 311 is located between the first link 10 and the second link 20, the partition plate 311 is located within the first clearance groove 120 to avoid interference between the partition plate 311 and the first link 10; and / or the surface of the second link 20 facing the drive body 306 is provided with a second clearance groove 212 for accommodating the partition plate 311. When the partition plate 311 is located between the first link 10 and the second link 20, the partition plate 311 is located within the second clearance groove 212 to avoid interference between the partition plate 311 and the second link 20.

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

[0262] During the engagement of the first tooth 301 with the first rack 101, the partition plate 311 is disposed 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 in the thickness direction along the mechanism box 6.

[0263] Optionally, the first power unit includes a first drive unit 303, and the first connecting rod 10 includes a drive engagement structure 115 that drives and engages with the first drive unit 303. The drive engagement structure 115 includes a first drive engagement part 104 and a connecting rod 109. The first drive unit 303 and the drive engagement structure 115 slide or roll together. The drive body 306 also includes a partition wall that protrudes outward along the radial direction of the wheel body 310. When the first drive unit 303 engages with the drive engagement structure 115, the partition wall is located between the drive engagement structure 115 and the second connecting rod 20 to separate the drive engagement structure 115 and the second connecting rod 20, that is, to separate the first connecting rod 10 and the second connecting rod 20, thus restricting the movement of the first connecting rod 10 and the second connecting rod 20 along the thickness direction of the mechanism box 6.

[0264] When the first drive unit 303 engages with the drive engagement structure 115, the engagement between the first drive unit 303 and the drive engagement structure 115 can restrict the movement of the first link 10 toward the second link 20, thus eliminating the need for a partition wall. Furthermore, the partition plate 311 is offset from the drive engagement structure 115; that is, during the engagement of the first drive unit 303 and the drive engagement structure 115, the partition plate 311 is not positioned between the first link 10 and the second link 20, meaning the partition plate 311 is not used for limiting the movement of the first link 10 and the second link 20 along the thickness direction of the mechanism box 6.

[0265] Optionally, the first power unit includes a first drive unit 303, and the first connecting rod 10 includes a drive engagement structure 115 that drives and engages with the first drive unit 303. The first drive unit 303 and the drive engagement structure 115 are in sliding or rolling engagement. The drive engagement structure 115 is provided with a third clearance groove 121. When the first drive unit 303 engages with the drive engagement structure 115, the drive body 306 is at least partially located in the third clearance groove 121 to avoid interference between the drive body 306 and the first connecting rod 10.

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

[0267] A second aspect of this utility model provides an air conditioner, including an indoor unit 80. The indoor unit 80 includes a housing, an indoor heat exchanger, a fan, an air guide plate 70, and a drive assembly for the air guide plate as described in any of the above embodiments. A first connecting rod 10 is directly rotatably connected to the air guide plate 70 via a first rotating shaft 501, and a second connecting rod 20 is directly rotatably connected to the air guide plate 70 via a second rotating shaft 502.

[0268] The casing defines an air duct and 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 through the air outlet 404. A guide vane 70 is located at the air outlet 404 to adjust the opening and closing of the air outlet 404 and the direction of airflow.

[0269] The air conditioner provided in the second aspect of this utility model includes a drive assembly for an air conditioner air guide plate as described in any of the above embodiments, and therefore has all the beneficial effects of the drive assembly for an air conditioner air guide plate as described in any 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, which is located inside the panel 403. The panel 403 has an air outlet 404, and the cover 405 has an opening 406. The mechanism box 6, the opening 406, and the air guide plate 70 are arranged sequentially. During the opening of the air guide plate 70, the first connecting rod 10 and the second connecting rod 20 extend through the opening 406.

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

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

[0273] The second connecting rod 20 is directly rotatably connected to the connecting part 702 via the second rotating shaft 502. For example, the second connecting rod 20 is provided with a third shaft hole 213, the connecting part 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; or, the second connecting rod 20 is provided with a third shaft hole 213, the second rotating shaft 502 is disposed in the connecting part 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, during 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 part 702 of the first rotating shaft 501 in the first position (e.g.) Figure 33 When the second rotating shaft 502 passes through the opening 406, the second rotating shaft 502 does not exceed the edge of the width direction of the connecting portion 702 when it is in the first position (as indicated by the arrow in the middle direction), 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 width direction of the connecting portion 702 when it is in the first position.

[0275] During 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 part 702 of the first rotating shaft 501 in the first position does not exceed the edge of the width direction of the connecting part 702 in the first position, or the orthographic projection of the first rotating shaft 501 on the connecting part 702 in the first position does not exceed the edge of the width direction of the connecting part 702 in the first position. In order to limit the movement amplitude of the first rotating shaft 501 when passing through the opening 406, the movement amplitude of the entire first connecting rod 10 is limited, thereby reducing the size of the cover 4. The opening 406 of the cover 405, and / or, when the second rotating shaft 502 passes through the opening 406, the second rotating shaft 502 in the first position does not exceed the edge of the width direction of the connecting part 702 in the first position, or the orthographic projection of the second rotating shaft 502 on the connecting part 702 in the first position does not exceed the edge of the width direction of the connecting part 702 in the first position, so as to limit the movement amplitude of the second rotating shaft 502 when passing through the opening 406, thereby limiting the movement amplitude of the entire second link 20, thereby reducing the opening 406 of the cover 405.

[0276] The connecting portion 702 has a first edge 703 and a second edge 704 disposed opposite to each other. When the first rotating shaft 501 passes through the opening 406, the first rotating shaft 501 does not extend beyond 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 extend beyond 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 extend beyond the edge of the connecting portion 702 in the width direction when it is in the first position. In this way, when the second connecting rod 20 passes through the opening 406, the second connecting rod 20 does not extend beyond 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 link 20 includes a second guide post 203 and a third guide post 205, such as Figure 33 In the process, the movement trajectory of the second guide post is B8B81B82, and the movement trajectory of the third guide post is B9B91 or B10B101. During the process of the air guide plate opening from the first position to the second position, the movement trajectory of the second guide post is B8B81; during the process of the air guide plate opening from the second position to the third position, the movement trajectory of the second guide post is B81B82. The mechanism box 6 is provided with a second guide groove 622 and a third guide groove 626. The second guide post 203 is located within the second guide groove 622 and can move relative to the second guide groove 622. The third guide post 205 is located within the third guide groove 626 and can move relative to the third guide groove 626, thereby guiding the movement trajectory of the second connecting rod 20.

[0278] The second guide post 203 is located between the third guide post 205 and the second rotating shaft 502. During the process of the air guide plate 70 opening from the second position to the third position, the third guide post 205 and the second rotating shaft 502 move in opposite directions. Moreover, under the constraint of the second guide groove 622, the second guide post 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 post 203. The second connecting rod 20 can be imagined as a lever, with the second guide post 203 as the fulcrum. At the same time, the second guide post 203 moves within the second guide groove 622. The second guide post 203 does not move relative to the second connecting rod 20. The third guide post 205 drives the second connecting rod 20 to rotate around the second guide post 203.

[0279] Optionally, during the process of the air guide plate 70 opening from the second position to the third position, the second guide post 203 does not extend beyond the edge of the width direction of the connecting portion 702 in the first position in the width direction.

[0280] The second guide post 203 serves as the rotation center of the second connecting rod 20. While satisfying the motion trajectory of the second rotating shaft 502 as B2B3, it ensures that the connecting part 702 of the second connecting rod 20 is always located between the first edge 703 and the second edge 704 in the width direction 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 width direction of the connecting part 702 in the first position in the width direction. 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 width direction of the connecting part 702 in the first position in the width direction, thereby limiting the size of the opening 406 and avoiding the opening 406 from being too large.
