[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] When the air guide plate is opened to a specific position, forcefully turning the air guide plate in the opposite direction will cause the gears and racks to disengage, especially when the rack is not straight, this phenomenon is more obvious.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0079] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0080] Example 1:

[0081] Combination Figures 1-11 As shown, this embodiment of the present disclosure provides a driving device for an air conditioning deflector, including a drive wheel 30, a first connecting rod 10, and a second connecting rod 20.

[0082] The drive wheel 30 is rotated in a controlled manner and includes a first toothed portion 301 and a second toothed portion 302; the first connecting rod 10 includes a first rack 101 for meshing with the first toothed portion 301 and connecting to the air guide plate 70, for example, by directly rotating and connecting 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 toothed portion 302 and connecting to the air guide plate 70, for example, by directly rotating and connecting to the air guide plate 70 through a second rotating shaft 502.

[0083] The drive wheel 30 rotates, driving 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.

[0084] 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.

[0085] Optionally, such as Figure 9a and Figure 9b As shown, the first tooth 301 and the second tooth 302 are coaxially arranged and rotate synchronously.

[0086] 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.

[0087] Optionally, the first tooth 301 is a non-circular gear, and the second tooth 302 is a cylindrical gear.

[0088] 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.

[0089] 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.

[0090] Optionally, the drive device 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, which meshes with a cylindrical gear. The cylindrical gear is fixedly connected to a non-circular gear. The motor 407 drives the reduction gear to rotate, which in turn drives the cylindrical gear to rotate, and the non-circular gear rotates with the cylindrical gear.

[0091] The reduction gear 40 is a cylindrical gear and the radius of the reduction gear is smaller than the radius of the second tooth 302.

[0092] Optionally, such as Figure 40 and Figure 41 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. 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 connecting rod 10 and / or the second connecting rod 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.

[0093] Optionally, both the first trajectory segment A1A2 and the third trajectory segment B1B2 are circular arcs.

[0094] This configuration simplifies the movement trajectory of the first link 10 and the second link 20, making the control logic of the drive device for the air conditioning deflector simpler, facilitating precise motion control, improving the reliability and stability of the system, and also making the movement of the deflector 70 smoother in the initial opening phase, reducing vibration and noise during the movement.

[0095] 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 extreme position, the first rotating shaft 501 reciprocates along the second trajectory segment A2A3, and at the extreme position, the first rotating shaft is located at point A2, and the second rotating shaft 502 moves from B2 to B3 along the fourth trajectory segment B2B3.

[0096] A fourth position can exist between the first and second positions, and a fifth position can exist between the second and the extreme positions. During the opening process, the air guide plate 70 sequentially passes through the first, fourth, second, fifth, and extreme positions. 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 extreme position is the heating downward airflow position. Alternatively, the fourth position is the heating downward airflow position, and the extreme position is the cooling horizontal airflow position.

[0097] When the air guide plate 70 opens from the second position to the limit 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 device for the air conditioning air guide plate inside the indoor unit 80.

[0098] 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 limit position.

[0099] 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.

[0100] During the movement of the air guide plate 70 from the second position to the extreme 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 B8, the first rotating shaft 501 is at position A8. Here, B8 is a point between B2 and B3 in the second trajectory segment B2B3, and A8 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 extreme position.

[0101] 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.

[0102] 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.

[0103] 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 same plane on the second link 20 are different when the second rotating 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. Furthermore, the instantaneous rotation centers of the points on the same plane constantly change, coordinating with the movement of the first rotating shaft 501 to achieve the movement of the air guide plate 70 from the second position to the limit position.

[0104] Optionally, such as Figure 12 and Figure 16 As shown, the second link 20 includes a third guide part 202 and a fourth guide part 204. During the opening of the air guide plate 70, the third guide part 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 fourth guide part 204 moves in one direction.

[0105] The fourth guide section 204 moves in one direction, while the third guide section 202 moves in a reciprocating motion. Through the reciprocating motion of the third guide section 202 and the one-way motion of the fourth guide section 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.

[0106] Optionally, the third guide section 202 is located between the fourth guide section 204 and the second rotating shaft 502. The movement trajectory of the second connecting rod 20 is realized through the movement trajectory of the second rotating shaft 502, the movement trajectory of the third guide section 202, and the movement trajectory of the fourth guide section 204, so as to meet the movement requirements of the air guide plate 70.

[0107] Optionally, during the process of the air guide plate 70 opening from the first position to the second position, both the third guide part 202 and the fourth guide part 204 move in one direction.

[0108] 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 third guide section 202 and the fourth guide section 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.

[0109] Optionally, during the process of the air guide plate 70 opening from the first position to the second position, the third guide part 202 and the fourth guide part 204 have the same movement trajectory. 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.

[0110] Optionally, during the process of the air guide plate 70 opening from the second position to the limit position, the fourth 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 fourth 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 be switched from the second position to the limit position.

[0111] Optionally, during the process of the air guide plate 70 opening from the second position to the extreme position, the movement trajectories of the third guide part 202 and the fourth guide part 204 are different, which allows the second link 20 to deflect instead of translate, thereby realizing the switching of the air guide plate 70 from the second position to the extreme position.

[0112] like Figures 1 to 6 As shown, the drive device 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 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.

[0113] The second cover 62 includes a third guide engagement part 621, which cooperates with the third guide part 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.

[0114] The second cover 62 also includes a fourth guide mating part 625, which cooperates with the fourth guide part 204, and the third guide mating part 621 cooperates with the third guide part 202 to jointly guide the movement trajectory of the second link 20.

[0115] like Figure 4As shown, one of the third guide mating part 621 and the third guide part 202 is a third guide groove 622, and the other is a third guide post 203. The third guide post 203 is adapted to the third guide groove 622, and the third guide post 203 is located in the third guide groove 622 and can slide relative to the third guide groove 622. One of the fourth guide mating part 625 and the fourth guide part 204 is a fourth guide groove 626, and the other is a fourth guide post 205. The fourth guide post 205 is adapted to the fourth guide groove 626, and the fourth guide post 205 is located in the fourth guide groove 626 and can slide relative to the fourth guide groove 626.

[0116] During the process of the air guide plate 70 opening from the first position to the second position, the movement direction of the second rotating shaft 502, the movement direction of the third guide part 202, and the movement direction of the fourth guide part 204 are all the same, and the movement trajectory of the second rotating shaft 502, the movement trajectory of the third guide part 202, and the movement trajectory of the fourth guide part 204 are all the same. That is, after translation, the movement trajectory of the second rotating shaft 502, the movement trajectory of the third guide part 202, and the movement trajectory of the fourth guide part 204 can overlap.

[0117] The third 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 third guide groove 622. During the process of the air guide plate 70 opening from the first position to the limit position, the third guide post 203 passes through the first sub-guide groove 623 and the second sub-guide groove 624 in sequence. The fourth 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 fourth guide groove 626. During the process of the air guide plate 70 opening from the first position to the limit position, the fourth 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.

[0118] like Figure 40 and Figure 41 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 third 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 fourth 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 third guide post 203 cooperates with the first sub-guide groove 623, and the fourth 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.

[0119] like Figure 40 and Figure 41 As shown, during the process of the air guide plate 70 opening from the second position to the limit position, the movement trajectory of the second rotating shaft 502 is B2B3, which is a non-circular arc. The third 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 fourth 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 third guide post 203 cooperates with the second sub-guide groove 624, and the fourth guide post 205 cooperates with the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence. When the fourth guide post 205 cooperates with the fourth sub-guide groove 628, the fourth guide post 205 and the second rotating shaft 502 have opposite movements. When the fourth guide post 205 cooperates with the low-speed sub-guide groove, the fourth 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.

[0120] like Figure 10 and Figure 11 As shown, the second connecting rod 20 includes a second tooth segment 207 for meshing with the second tooth 302. The pitch line of the second tooth segment 207 is a non-circular arc 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 limit position, and the corresponding motion trajectory of the second rotating shaft 502 is a non-circular arc trajectory B2B3.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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, during the opening of the air guide plate 70, the third guide portion 202 has reciprocating motion, and the fourth guide portion 204 has unidirectional motion.

[0126] The pitch line of the second tooth segment 207 satisfies the following: during the meshing of the second tooth portion 302 and the second tooth segment 207, the second rotating shaft 502 and the fourth guide portion 204 exhibit opposite movements. The pitch line of the second tooth segment 207 also satisfies the following: during the meshing of the second tooth portion 302 and the second tooth segment 207, the second rotating shaft 502 and the fourth guide portion 204 exhibit the same direction of movement.

[0127] Optionally, the second connecting rod 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 connecting rod 20, and the pitch line D5D6 of the first tooth segment 206 is arc-shaped.

[0128] 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.

[0129] 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.

[0130] 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 third guide segment 202 and the fourth guide segment 204 are the same.

[0131] The first cover 61 is provided with a first guide mating part 611 and a second guide mating part 632. The first connecting rod 10 includes a first guide part 102 and a second guide part 123. One of the first guide part 102 and the first guide mating part 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. One of the second guide part 123 and the second guide mating part 632 is a second guide groove 633, and the other is a second guide post 124. The second guide post 124 is adapted to the second guide groove 633. The second guide post 124 is located in the second guide groove 633 and can slide relative to the second guide groove 633, so as to jointly guide the movement trajectory of the first connecting rod 10.

[0132] When the first rotating shaft 501 moves along the first trajectory segment A1A2, the first guide post moves in one direction within the first guide groove, and the second guide post 124 moves in one direction within the second guide groove 633; ​​when the first rotating shaft 501 reciprocates along the second trajectory segment A2A3, the first guide post reciprocates within the first guide groove, and the second guide post 124 reciprocates within the second guide groove 633612.

[0133] like Figure 40 and Figure 41 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 D5D6 of the first tooth segment 206 is B0. Figure 31 As shown, the pitch line of the second tooth 302 is a circle E1, the pitch line of the first tooth 301 is a non-circular curve C5C6, the pitch line of the second rack 201 includes D5D6, and the non-circular curve C5C7 is the pitch line of the first rack 101.

[0134] The C5C7 curve corresponds to A1A2, which is not a circular arc; the first link rotates during the C5C7 process, not translates.

[0135] D5D6 corresponds to the process of the second rotating axis moving along B1B2, which is an arc shape.

[0136] The circle E1 is concentric with the non-circular curve C5C6, and the center of rotation is E.

[0137] 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.

[0138] Air guide plate 70 changes from closed position to cooling flat-blowing position to maximum airflow position:

[0139] The first rotating shaft 501 moves from A1 along the arc A1A2 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.

[0140] 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.

[0141] The first rotating shaft 501 starts from A2 and moves back and forth on 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 is the first rotating shaft 501 corresponding to the second rotating shaft.

[0142] Optionally, during the movement of the air guide plate 70, the transmission ratio i of the first tooth 301 and the first rack 101 is constrained by the angular velocity ωA of the first rotating shaft 501 and the angular velocity ωB of the second rotating shaft 502.

[0143] 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.

[0144] 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.

[0145] like Figure 44As shown, a coordinate system is established with A0 as the coordinate 0 and the direction of A0B0 as the X-axis. Simplifying the formula, let A0B0 = L1, A0D0 = L2, B0C0 = L3, C0D0 = L4, ∠XA0D0 = A, ∠XB0C0 = B, ∠C1C0D0 = C (C1C0 is parallel to the X-axis). When the air guide plate is in the closed position, the first rotation axis is located at point C0, and the second rotation axis is located at point D0. ∠XA0D0 is the angle between the positive X-axis and A0D0, and ∠XB0C0 is the angle between the positive X-axis and B0C0. A1A2 is an arc with B0 as its center. During the movement of the first rotation axis from A1 to A2, the angular velocity of the first rotation axis around B0 is ω. B B1B2 is an arc with center A0. During the movement of the second rotating shaft from B1 to B2, the angular velocity of the second rotating shaft about A0 is ω. A The angular velocity of C0D0 rotating about axis C0 is ω C 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 around the first rotation axis, i.e., the rate of change of rotation of C. This can be derived from the principles of linkage mechanisms:

[0146] L1+L3*cosB+L4*cosC=L2*cosA ①

[0147] L3*sinB - L4*sinC = L2*sinA ②

[0148] The variables in the formula are A, B, and C; differentiating equations ① and ② with respect to time T, we get

[0149] -L3*sinB*ω B -L4*sinC*ω C =-L2*sinA*ω A ③

[0150] L3*cosB*ω B -L4*cosC*ω C =L2*cosA*ω A ④

[0151] Combining equations ① to ④, we can obtain

[0152]

[0153] Let m = L3*sinB - L2*sinA, n = L2*cosA - L3*cosB - L1, simplifying equation ⑤, we can obtain the ratio of the angular velocities of the first and second rotation axes, that is:

[0154]

[0155] To simplify the design, a fixed transmission ratio (i.e., uniform speed transmission) is selected for the second tooth and the first tooth segment 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 driving wheel and the radius R1 of E1, and the radius L5 of D5D6 are determined. L5 is different from the rotation radius of the first rotating shaft.

[0156] Let the angular velocity of the drive wheel be ω1, the radius of C5C6 be r1, the radius of C5C7 be r2, and the initial angle of B be θ1, i.e., when the guide vane is in the closed position, B = θ1. The center distance B0E = a, then...

[0157]

[0158]

[0159] By combining equations ⑦ and ⑧, the transmission ratio i can be obtained.

[0160]

[0161] The equations for nodal lines C5 and C6 are:

[0162]

[0163] The equations for nodal lines C5 and C7 are:

[0164]

[0165] φ is 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.

[0166] Combined ⑤, ⑥, ⑨, ⑩ The formula is imported into mathematical calculation software, a calculation program is written, and the pitch lines C5C6 and C5C7 are drawn. The pitch curve is then imported into 3D drawing software, and the tooth profile is drawn according to the tooth profile design method (e.g., the method disclosed in application number CN202310777054.8).

[0167] The above transmission ratio applies to the stage where the second rotating shaft moves along B1B2.

[0168] like Figure 1 , Figure 2 and Figure 7 As shown, the first lid 61 is provided with a first limiting part, and the second lid 62 is provided with a second limiting part; the second connecting rod 20 is provided with a first limiting engagement part that cooperates with the first limiting part and a second limiting engagement part that cooperates with the second limiting part, so as to restrict the movement of the second connecting rod 20 in the direction of the line connecting the first lid 61 and the second lid 62.

[0169] Optionally, the first limiting part includes a limiting area formed by the first cover 61 protruding toward the second link 20, which reduces the distance between the limiting area and the second link 20, thereby facilitating the contact and engagement between the first limiting part and the first limiting mating part. Moreover, the limiting area can also enhance the strength of the first cover 61. The first limiting mating part includes a first limiting post provided on the second link 20, which abuts against the limiting area and can move relative to the limiting area.

[0170] During the opening of the air guide plate 70, the second link 20 moves, and the first limiting engagement part moves with the second link 20. Therefore, the size of the limiting area needs to ensure that the limiting area can always contact the first limiting engagement part throughout the entire stroke of the first limiting engagement part.

[0171] Optionally, one of the first limiting part and the first limiting mating part includes a first limiting groove, and the other includes a first limiting post, wherein the first limiting post is located in the first limiting groove and is capable of moving relative to the first limiting groove.

[0172] The third guide mating part 621 and / or the fourth guide mating part 625 can be used as the second limiting part, that is, the second limiting part includes the third guide mating part 621 and / or the fourth guide mating part 625. Correspondingly, the second limiting part includes the third guide mating part 621 and the fourth guide mating part, which simplifies the structure of the second cover 62 and the second connecting rod 20.

[0173] Optionally, such as Figure 7 As shown, the drive device for the air conditioning deflector also includes a third limiting part, which is supported between the first link 10 and the second link 20.

[0174] The third limiting part is fixedly installed on the first link 10 or the second link 20 and is made of wear-resistant material. The third limiting part 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.

[0175] 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.

[0176] 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.

[0177] 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.

[0178] Optionally, such as Figure 8 As shown in Figure 9, the drive wheel 30 includes a first surface 304 and a second surface 305 disposed opposite to each other. The first tooth 301 and the first drive part 303 are both disposed on the first surface 304, and the first tooth and the first drive part are located at the same height in the drive wheel axial direction.

[0179] 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.

[0180] Optionally, the first tooth 301 extends circumferentially along the drive wheel 30 and is non-circular.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] 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.

[0185] 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.

[0186] like Figure 9a and Figure 9b 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.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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.

[0191] 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.

[0192] 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.

[0193] Optionally, such as Figure 7 and Figure 8 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.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0198] 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.

[0199] 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.

[0200] Optionally, such as Figure 10 and Figure 11 As shown, the second rack 201 is a non-linear rack.

[0201] 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.

[0202] Optionally, such as Figure 10 and Figure 11 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 D5D6 of the first tooth segment 206 is arc-shaped, and the pitch line D6D7 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.

[0203] The pitch line D6D7 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.

[0204] 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.

[0205] During the process of the air guide plate 70 opening from the first position to the limit 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.

[0206] 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.

[0207] 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.

[0208] 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.

[0209] Optionally, such as Figure 7 and Figure 8 As shown, the first rack 101 is a non-linear rack.

[0210] 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.

[0211] 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.

[0212] 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.

[0213] The rotation axis of the drive wheel 30 is set perpendicular to the first surface 304 and the second surface 305.

[0214] The first link 10 and the second link are located inside the mechanism box 6 and move 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.

[0215] The drive unit for the air conditioning deflector also includes a power source, which includes drive wheels 30.

[0216] like Figure 6As shown, the mechanism box 6 is provided with a stroke restriction area 636; 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 636; wherein, during the movement of the first link 10, the drive engagement structure 115 is at least partially located within the stroke restriction area 636 and moves relative to the stroke restriction area 636, so that the stroke restriction area 636 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.

[0217] Optionally, the first link 10 is located between the power source and the first cover 61, and the travel restriction area 636 is located on the first cover 61. On the one hand, the distance between the first link 10 and the travel restriction area 636 is small, which facilitates the cooperation between the first link 10 and the travel restriction area 636; on the other hand, the cooperation between the drive cooperation structure 115 and the travel restriction area 636 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.

[0218] 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 636. 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.

[0219] 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.

[0220] During the movement of the first link 10, the connecting rod 109 is located within the travel restriction area 636 and moves relative to the travel restriction area 636, so that the travel restriction area 636 defines the movement area of ​​the drive engagement structure 115.

[0221] The limiting effect of the travel restriction area 636 on the drive engagement structure 115 is achieved by limiting the connecting rod 109 through the travel restriction area 636, rather than by limiting the first drive engagement part 104 through the travel restriction area 636. This ensures that the limiting effect of the travel restriction area 636 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.

[0222] Optionally, the first box cover 61, the connecting rod 109, and the first rod body 114 are arranged sequentially.

[0223] The first guide portion includes a second limiting post 125, which is disposed on the connecting rod at a position corresponding to the first drive post. The second limiting post 125 and the first drive post are respectively located on opposite sides of the connecting rod. The second limiting post 125 is located within the travel limiting area and moves relative to the travel limiting area with the movement of the first connecting rod, and abuts against the side wall of the travel limiting area to limit the position of the first connecting rod relative to the mechanism box.

[0224] 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.

[0225] 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.

[0226] Optionally, the second tooth 302 extends circumferentially along the drive wheel 30 and is either annular or non-annular.

[0227] 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.

[0228] 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.

[0229] Optionally, the drive wheel 30 includes a drive body 306, with a first power unit on one side (i.e., the side where the first surface 304 is located) and a second power unit on the other side (i.e., the side where the second surface 305 is located); a first connecting rod 10 is located on one side of the drive body 306 and is drivenly connected to the first power unit, and the first connecting rod 10 is drivenly connected to the air guide plate 70; a second connecting rod 20 is located on the other side of the drive body 306 and is drivenly connected to the second power unit, and the second connecting rod 20 is drivenly connected to the air guide plate 70; wherein, the drive body 306 is used to separate the first connecting rod 10 and the second connecting rod 20.

[0230] like Figure 1 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).

[0231] 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.

[0232] 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.

[0233] 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.

[0234] 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.

[0235] 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.

[0236] 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.

[0237] 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.

[0238] 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.

[0239] 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.

[0240] 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.

[0241] The second link is provided with a positioning part 216, and the mechanism box is provided with a positioning mating part 630. The positioning part 216 and the positioning mating part 630 cooperate to provide the second link with a constraint along the radial direction of the drive wheel.

[0242] By providing a positioning part 216 on the second connecting rod and a positioning mating part 630 on the mechanism box, the second connecting rod can obtain effective radial constraint along the drive wheel during movement. This design effectively solves the problem of rack tooth dislodgement when the air guide plate is at its extreme position in the prior art, ensuring that the second connecting rod remains stable during movement and avoiding radial deformation or tooth dislodgement caused by external forces, thereby improving the stability and reliability of the air guide plate's movement.

[0243] Optionally, the second link includes a first end 214 and a second end 215 in the length direction, the first end 214 being movably connected to the air guide plate, and the positioning part 216 being disposed at the second end 215.

[0244] The second end 215 is far from the middle of the second connecting rod and is a free end, making it more prone to deformation. This makes the second end 215 more susceptible to tooth loss. Therefore, by placing the positioning part 216 on the second end 215, it is possible to prevent the second end 215 from disengaging from the second tooth during movement.

[0245] Optionally, one of the positioning part 216 and the positioning mating part 630 includes a positioning post 217, and the other includes a positioning groove 631. The positioning post 217 is disposed in the positioning groove 631 and can slide relative to the positioning groove 631.

[0246] The positioning post 217 is adapted to the positioning groove 631, and the positioning mating part 630 is provided on the first cover or the second cover. By adding the positioning post 217 and the positioning groove 631, the constraint force between the second link and the mechanism box is increased, thereby enhancing the stability of the second link position and preventing the second link from disengaging from the second tooth during movement.

[0247] Optionally, such as Figures 32 to 34 As shown, when the air guide plate is opened to the limit position, the surface of the positioning part 216 that is radially away from the center of the drive wheel abuts against the positioning mating part 630 to restrict the movement of the second link radially outward along the drive wheel.

[0248] The drive wheel can restrict the movement of the second link radially inward along the drive wheel. Therefore, the positioning part 216 and the positioning mating part 630 are provided to restrict the movement of the second link radially outward along the drive wheel. The direction closer to the rotation center of the drive wheel is inward, and the direction farther away from the rotation center of the drive wheel is outward.

[0249] Optionally, the positioning part 216 includes a first positioning protrusion 218, and the positioning mating part 630 includes a second positioning protrusion 635. The inner wall of the first cover protrudes inward to form the second positioning protrusion 635. When the air guide plate is opened to the limit position, the surface of the first positioning protrusion 218 that is radially away from the middle of the drive wheel abuts against the second positioning protrusion 635 to restrict the movement of the second connecting rod radially outward along the drive wheel.

[0250] Optionally, the first positioning protrusion 218 is provided on the surface of the second link opposite to the drive wheel.

[0251] Thus, the first positioning protrusion 218 is located between the first lid and the second lid, so that in addition to preventing the second link from dislodging at the extreme position, the first positioning protrusion 218 can also restrict the movement of the first link in the direction of the line connecting the first lid and the second lid.

[0252] Optionally, such as Figure 10 , Figure 11 , Figure 37 and Figure 38 As shown, the second link is provided with a third guide portion and a fourth guide portion. The third guide portion and the fourth guide portion are located between the first end 214 and the second end 215 of the second link, which enhances the motion guidance of the second link in the mechanism box, so that the second link can slide more smoothly along the preset trajectory during the movement.

[0253] Since the third guide portion and the fourth guide portion are located between the first end 214 and the second end 215 of the second connecting rod, and the third guide portion and the fourth guide portion are far from the second end 215, the second end 215 is more prone to tooth loss.

[0254] Optionally, the surface of the second link away from the drive wheel is provided with a relief groove 222, and the first positioning protrusion 218 is partially disposed in the relief groove 222, thereby reducing the length of the first positioning protrusion 218 extending out of the second link and reducing the volume occupied by the second link during movement.

[0255] Optionally, the second positioning protrusion 635 includes a protrusion body 220 and a positioning wheel 221. The protrusion body 220 is connected to the second connecting rod. The positioning wheel 221 is sleeved on the surface of the protrusion body 220 and is made of a different material than the protrusion body 220. At the extreme position, the positioning wheel 221 abuts against the second positioning protrusion 635.

[0256] The surface of the second positioning protrusion 635 facing the first positioning protrusion 218 has a bend 637. In the extreme position, the first positioning protrusion 218 is located at the bend 637 to better limit the position of the first positioning protrusion 218.

[0257] The protruding body 220 is fixedly connected to the second connecting rod or is an integral structure. Using a positioning wheel 221 made of a different material than the positioning protrusion effectively improves the wear resistance and impact resistance of the positioning structure. The positioning wheel 221 can be supported by a wear-resistant material. When the positioning wheel 221 abuts against the first positioning protrusion 218, it can better withstand external forces, reducing the risk of wear and damage and extending the service life of the positioning structure.

[0258] like Figure 40 and Figure 41 As shown, during the opening process of the air guide plate, the movement trajectory of the first rotating shaft includes a first trajectory segment A1A2 and a second trajectory segment A2A3. The movement trajectory of the second rotating shaft includes a third trajectory segment B1B2 corresponding to the first trajectory segment A1A2 and a fourth trajectory segment B2B3 corresponding to the second trajectory segment A2A3. The second trajectory segment A2A3 is offset from the first trajectory segment A1A2 and located on one side of the first trajectory segment A1A2, so as to cause the first connecting rod to deflect. The fourth trajectory segment B2B3 is offset from the third trajectory segment B1B2 and located on one side of the third trajectory segment B1B2, so as to cause the second connecting rod to deflect.

[0259] Offset refers to both translation and rotation, collectively known as offset or deflection.

[0260] The first and second links are offset, which allows the first and second links to change the opening angle and extension displacement of the air guide plate to a large extent, thus enabling the air guide plate to have multiple air guiding positions.

[0261] Optionally, the second trajectory segment A2A3 is located on the side of the first trajectory segment A1A2 facing the third trajectory segment B1B2. During the opening of the air guide plate, the second trajectory segment A2A3 is tilted towards the third trajectory segment B1B2. During the opening of the air guide plate, the second trajectory segment A2A3 is tilted towards the end point B2 of the third trajectory segment B1B2.

[0262] This configuration ensures that as the first rotating shaft moves along the second trajectory segment A2A3, it gradually approaches the third trajectory segment B1B2 and then point B2. The closer it gets to point B2, the shorter the length of the line connecting B2 and B3 (B2 and B3 are connected by a straight line, the longer the line), meaning the shorter the distance between B2 and B3, and the smaller its dimensions, resulting in a smaller mechanism box size. Furthermore, the coordination of the motion trajectories of the first and second rotating shafts allows the air guide plate to be driven to the target position.

[0263] Optionally, during the opening of the air guide plate, the first rotating shaft reciprocates along the second trajectory segment A2A3, which can shorten the stroke of the first link and reduce the space occupied by the first link during its movement.

[0264] The first trajectory segment A1A2 can be a straight line or a curve. The second trajectory segment A2A3 can be a straight line or a curve. The third trajectory segment B1B2 can be a straight line or a curve. The fourth trajectory segment B2B3 can deviate from either a straight line or a curve.

[0265] Optionally, when the air guide plate is opened to the limit position, the first rotating shaft returns to point A2, which can shorten the movement stroke of the first link. Since the relative positions of the second rotating shaft and the second rotating shaft remain unchanged, the movement stroke of the second link can be shortened, thereby reducing the space occupied by the entire drive device for the air conditioning air guide plate.

[0266] Optionally, during the process of the air guide plate moving from the closed position to the maximum air supply position, the first rotating shaft moves along the first trajectory segment A1A2; during the process of the air guide plate moving from the maximum air supply position to the limit position, the first rotating shaft moves along the second trajectory segment A2A3.

[0267] In this design, at the position of maximum air supply, the air guide plate is located in the middle of the air outlet, that is, the air outlet direction is perpendicular to the plane enclosed by the length and width of the air guide plate.

[0268] Optionally, during the opening of the air guide plate, the movement trajectory of the first rotating shaft includes a first trajectory segment A1A2 and a second trajectory segment A2A3; the movement trajectory of the first guide part includes a fifth trajectory segment C1C2 and a sixth trajectory segment C2C3; and the movement trajectory of the second guide part 123 includes a seventh trajectory segment D1D2 and an eighth trajectory segment D2D3. The first trajectory segment A1A2, the fifth trajectory segment C1C2, and the seventh trajectory segment D1D2 correspond to each other, and the second trajectory segment A2A3, the sixth trajectory segment C2C3, and the eighth trajectory segment D2D3 correspond to each other. The second trajectory segment A2A3 is located on the first side of the first trajectory segment A1A2 (approximately below A1A2), the sixth trajectory segment C2C3 is located on the third side of the fifth trajectory segment C1C2 (approximately below C1C2), and the eighth trajectory segment D2D3 is located on the fifth side of the seventh trajectory segment D1D2 (approximately below D1D2). The first side, the third side, and the fifth side are the same side, so that when the first rotation axis moves from moving along the first trajectory segment A1A2 to moving along the second trajectory segment A2A3, the first connecting rod shifts to the same side.

[0269] The second trajectory segment A2A3 is located on the first side of the first trajectory segment A1A2, the sixth trajectory segment C2C3 is located on the third side of the fifth trajectory segment C1C2, and the eighth trajectory segment D2D3 is located on the fifth side of the seventh trajectory segment D1D2. The first, third, and fifth sides are the same side, so that when the first rotating shaft moves from the first trajectory segment A1A2 to the second trajectory segment A2A3, the first connecting rod shifts in the same direction as a whole. This direction is the direction of the first, third, and fifth sides, which enriches the movement trajectory of the air guide plate. This allows the air guide plate to achieve more precise and flexible air delivery direction adjustment during the opening process, and can effectively reduce the interference between the first connecting rod and other mechanical parts.

[0270] C1C2 and D1D2 are arc-shaped.

[0271] Optionally, the second trajectory segment A2A3, the sixth trajectory segment C2C3, and the eighth trajectory segment D2D3 do not overlap after translation, so that the motion trajectories at the first rotation axis, the first guide part, and the second guide part 123 on the first connecting rod are different. In this way, the first connecting rod will not only undergo translational motion, but also rotational motion, that is, it will deflect.

[0272] The second trajectory segment A2A3, the sixth trajectory segment C2C3, and the eighth trajectory segment D2D3 can be either straight lines or curves.

[0273] Optionally, the second guide portion 123 is located between the first guide portion and the first rotating shaft, and the inclination of the second trajectory segment A2A3 is greater than the inclination of the eighth trajectory segment D2D3, and the inclination of the eighth trajectory segment D2D3 is greater than the inclination of the sixth trajectory segment C2C3.

[0274] The first rotating shaft, the second guide section 123, and the first guide section are arranged sequentially. The second trajectory segment A2A3 has the largest inclination, followed by the eighth trajectory segment D2D3, and the sixth trajectory segment C2C3 has the smallest inclination. This effectively reduces the swaying and offset of the first connecting rod during movement, improving the stability of the movement. Moreover, the distance between the first rotating shaft and the air guide plate is the smallest, and the inclination of the second trajectory segment A2A3 is the largest, thus allowing for a significant adjustment of the air guide plate's position and enriching the air guide plate's airflow guidance positions.

[0275] During the opening of the air guide plate, the second guide part 123 reciprocates along the eighth trajectory segment D2D3, moving from D2 to D3. When the air guide plate reaches its limit position, it returns to D2. Similarly, the first guide part reciprocates along the sixth trajectory segment C2C3, moving from C2 to C3. When the air guide plate reaches its limit position, it returns to C2. Specifically, when the first rotating shaft moves to B2, the first guide part is located at C2, and the second guide part 123 is located at D2. When the first rotating shaft moves to B3, the first guide part is located at C3, and the second guide part 123 is located at D3. At the limit position, the first rotating shaft returns to B2, the first guide part is located at C2, and the second guide part 123 is located at D2.

[0276] A1A2, C1C2, and D1D2 are all circular arcs located at the same center, but with different radii. Although the radii are different, the angular velocities are the same, so there is no deflection when the first rotation axis moves along A1A2.

[0277] Example 2:

[0278] The difference from Embodiment 1 is that, as Figures 12 to 39 , Figures 42 to 45 As shown, during the opening of the air guide plate, the first rotating shaft moves unidirectionally along the second trajectory segment A2A3.

[0279] In this design, at the maximum air supply position, the air guide plate extends beyond the lower edge of the air outlet and is not located in the middle of the air outlet. This extends the length of the air duct and prevents the air guide plate from blocking the wind.

[0280] Optionally, such as Figure 43 As shown, the second trajectory segment A2A3 is located on the first side of the first trajectory segment A1A2, and the sixth trajectory segment C2C3 is located on the fourth side of the fifth trajectory segment C1C2. The first side and the fourth side are opposite sides. (Where, as...) Figure 43 In the middle, the first and fourth sides are the upper sides.

[0281] The first side and the fourth side are opposite sides. When the first rotating shaft moves along the second trajectory segment A2A3, the first connecting rod not only performs translational motion but also rotational motion, forming a deflection motion. This reduces the opening of the first connecting rod in the cover, similar to the principle of changing the motion trajectory of the second connecting rod to reduce the opening of the corresponding second connecting rod on the cover.

[0282] Optionally, the eighth trajectory segment D2D3 is located on the fifth side of the seventh trajectory segment D1D2, with the first and fifth sides being the same side and the fifth side being the lower side.

[0283] When the first rotating shaft moves along the second trajectory segment A2A3, it is equivalent to the first connecting rod rotating around the second guide part 123, forming the deflection motion of the first connecting rod, thereby reducing the opening on the cover corresponding to the first connecting rod.

[0284] Alternatively, the first and fifth sides can be opposite sides, meaning the fifth and fourth sides can be the same side.

[0285] The inclination of the second trajectory segment A2A3 is greater than that of the eighth trajectory segment D2D3; and / or the inclination of the sixth trajectory segment C2C3 is greater than that of the eighth trajectory segment D2D3.

[0286] This configuration ensures that when the first rotating shaft moves along the second trajectory segment A2A3, it is equivalent to the first connecting rod rotating around the second guide portion 123, thereby reducing the opening of the cover.

[0287] During the opening of the air guide plate, the second tooth and the second rack first engage externally and then internally; the pitch line of the second rack includes the second segment D6D7, which corresponds to the internal engagement, and the radius of curvature of the second segment D6D7 changes continuously.

[0288] During the internal meshing of the second tooth with the second rack, the pitch line of the second rack includes the second pitch segment D6D7. The radius of curvature of the second pitch segment D6D7 changes continuously, making it neither a circular arc nor a straight line. The continuous change in the radius of curvature makes the second pitch segment D6D7 smooth and gradual, unlike the combination of multiple circular arcs and straight lines in comparative document 1. This makes the movement of the second link smoother, and also makes the third and fourth guide grooves smoother. It does not include the form of multiple guide segments as in the related technology, nor does it include the multiple straight transition segments as in the related technology, thus reducing the length of the second link.

[0289] Optionally, such as Figure 45As shown, the pitch line of the second rack also includes: the first pitch line segment D5D6, which corresponds to the external meshing and is connected to the second pitch line segment D6D7; the first pitch line segment D5D6 is arc-shaped and has the same center as the third trajectory segment B1B2. D5D6 and B1B2 can have the same radius or different radii.

[0290] When the second tooth engages with the second rack, the pitch line of the second rack is the first pitch line segment D5D6. D5D6 and the third trajectory segment B1B2 are both arcs with the same center, thus satisfying the motion trajectory requirements of the second link.

[0291] Optionally, the tangent at the connection point between the first segment D5D6 and the second segment D6D7 coincides with the tangent at the connection point between the second segment D6D7 and the first segment D5D6, so that the first segment D5D6 and the second segment D6D7 are smoothly connected, thereby improving the smoothness of the second rack movement.

[0292] The pitch line of the second rack also includes a third segment F3F4, which is located at the end of the second segment D6D7 away from the first segment D5D6; the radius of curvature of the third segment F3F4 remains unchanged, for example, it is an arc.

[0293] Optionally, during the process of the air guide plate moving from the closed position to the maximum air supply position, the second tooth engages externally with the second rack; during the process of the air guide plate moving from the maximum air supply position to the limit position, the second tooth engages internally with the second rack.

[0294] like Figure 42 As shown, if the second tooth and the second rack are always internally meshed during the movement of the air guide plate from the closed position to the limit position, the movement trajectory of the second rack will be biased downwards, as shown in the figure. Figure 42 As shown in Figure F111, the opening in the casing is positioned too low near the lower edge of the air outlet, resulting in an unsightly appearance for the indoor unit. Furthermore, the upper trajectory of the second rack is too close to the front panel, making the overall spatial structure difficult to design. If the second tooth and the second rack remain in external engagement throughout the movement of the air guide plate from the closed position to its limit position, the trajectory of the second rack will be higher at the lower end compared to when it is in internal engagement. Figure 42 As shown in F131, the distance from the lower edge of the air outlet is greater, the upper end is also thicker, and the distance from the front panel is increased. Among them, during the opening of the air guide plate, the second rotating shaft moves from point F00 to point F01. F11 is the trajectory of the second rotating shaft in the case of internal engagement, F12 is the linear association between F00 and F01, and F13 is the trajectory of the second rotating shaft in the case of external engagement.

[0295] Therefore, the second tooth engages externally and then internally with the second rack, which prevents the upper end of the second rack from getting too close to the front panel and also prevents the lower end from getting too close to the lower edge of the air outlet. The front panel is the front wall of the indoor unit, located above the air outlet, and covers the front side of the casing.

[0296] 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 driving device 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.

[0297] 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.

[0298] The air conditioner provided in the second aspect of this utility model includes a driving device for an air conditioner air guide plate as described in any of the above embodiments, and therefore has all the beneficial effects of the driving device for an air conditioner air guide plate as described in any of the above embodiments, which will not be repeated here.

[0299] like Figure 29 As shown, the housing includes a front panel 403, and the indoor unit 80 also includes a cover 405, which is located inside the front panel 403. The front 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.

[0300] 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.

[0301] 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.

[0302] 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.

[0303] like Figure 39 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 22 When the first edge 703 to the second edge 704 is in the first position, 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, 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.

[0304] 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.

[0305] 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.

[0306] The second link 20 includes a third guide post 203 and a fourth guide post 205. The mechanism box 6 is provided with a third guide groove 622 and a fourth guide groove 626. The third guide post 203 is located in the third guide groove 622 and can move relative to the third guide groove 622. The fourth guide post 205 is located in the fourth guide groove 626 and can move relative to the fourth guide groove 626, so as to guide the movement trajectory of the second link 20.

[0307] The third guide post 203 is located between the fourth 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 limit position, the fourth guide post 205 and the second rotating shaft 502 have opposite movements. Moreover, under the constraint of the third guide groove 622, the third guide post 203 moves along the length direction of the third guide groove 622. This can be understood as the second connecting rod 20 rotating around the third guide post 203. The second connecting rod 20 can be imagined as a lever, and the third guide post 203 is the fulcrum of the lever. At the same time, the third guide post 203 moves within the third guide groove 622. The third guide post 203 does not move relative to the second connecting rod 20. The fourth guide post 205 drives the second connecting rod 20 to rotate around the third guide post 203.

[0308] Optionally, during the process of the air guide plate 70 opening from the second position to the limit position, the third guide post 203 does not extend beyond the edge of the width direction of the connecting part 702 in the first position in the width direction.

[0309] The third 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.

[0310] Optionally, during the process of the air guide plate 70 opening from the second position to the limit 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.

[0311] The indoor unit also includes a small guide plate 705. The small guide plate and the air guide plate are arranged sequentially along the width of the air outlet, and together they close the air outlet and adjust the air outlet direction.
