Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to a driving device for an air conditioner air guide plate and an air conditioner. Background Technology

[0002] Currently, air conditioners are equipped with air guide plates at the air outlet. The movement of the air guide plates controls the air volume and direction of the air outlet, thus achieving air guidance.

[0003] A related technology discloses a drive mechanism for an air guide vane in an air conditioner, comprising a linkage assembly and a rotating member. The linkage assembly includes a first link and a second link. The first link is configured to be rotatably connected to the air guide vane; the second link is configured to be rotatably connected to the air guide vane; the rotating member includes a first drive portion droopingly connected to the first link and a second drive portion droopingly connected to the second link. When the rotating member rotates in a set direction, the first drive portion drives the first link to move, and the second drive portion drives the second link to move, thereby opening the air guide vane. The first and second drive portions are in the form of drive columns, and the corresponding first and second links are provided with drive grooves adapted to the drive columns, so that the rotating member drives the first and second links to move, thereby realizing the opening and closing of the air guide vane.

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

[0005] The long-term contact between the drive column and the drive groove will cause wear on both, thus affecting the movement accuracy of the air guide plate.

[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. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a driving device for an air guide plate in an air conditioner and an air conditioner, in order to solve the wear problem of the driving column and driving groove in the related art.

[0009] According to a first aspect of the present invention, a driving device for an air guide plate of an air conditioner is provided, comprising: a drive wheel, which is controlled to rotate and includes a first tooth, a first driving part, a second tooth, and a second driving part; a first connecting rod, including a first rack and a first driving engagement part, wherein the first rack and the first tooth can mesh, and the first driving part and the first driving engagement part can slide or roll, and the first connecting rod and the air guide plate are rotatably connected via a first rotating shaft; and a second connecting rod, including a second rack and a second driving engagement part, wherein the second rack and the second tooth can mesh, and the second driving part and the second driving engagement part can slide or roll, and the second connecting rod and the air guide plate are rotatably connected via a second rotating shaft; during the opening of the air guide plate, the first rotating shaft sequentially moves along... The first trajectory segment A1A2, the first transition trajectory segment A2A3, and the second trajectory segment A3A4 move, while the second rotating shaft moves sequentially along the third trajectory segment B1B2, the second transition trajectory segment B2B3, and the fourth trajectory segment B3B4. Specifically, the first trajectory segment A1A2 corresponds to the third trajectory segment B1B2, the first transition trajectory segment A2A3 corresponds to the second transition trajectory segment B2B3, and the second trajectory segment A3A4 corresponds to the fourth trajectory segment B3B4. The first transition trajectory segment A2A3 corresponds to the switching from the engagement of the first tooth and the first rack to the engagement of the first drive unit and the first drive mating unit. The second transition trajectory segment B2B3 corresponds to the switching from the engagement of the second tooth and the second rack to the engagement of the second drive unit and the second drive mating unit.

[0010] Optionally, the first transition trajectory segment A2A3 has a different shape than the first trajectory segment A1A2, and / or the second transition trajectory segment B2B3 has a different shape than the third trajectory segment B1B2.

[0011] Optionally, the first transition trajectory segment A2A3 has a different shape than the second trajectory segment A3A4, and / or the second transition trajectory segment B2B3 has a different shape than the fourth trajectory segment B3B4.

[0012] Optionally, the first trajectory segment A1A2, the first transition trajectory segment A2A3, and the second trajectory segment A3A4 have the same shape.

[0013] Optionally, the first trajectory segment A1A2, the first transition trajectory segment A2A3, and the second trajectory segment A3A4 are all circular arcs and located on the same circumference.

[0014] Optionally, the third trajectory segment B1B2 is an arc shape, while the second transition trajectory segment B2B3 and the fourth trajectory segment B3B4 are both non-circular arc shapes.

[0015] Optionally, during the opening of the air guide plate, the first rotating shaft reciprocates along the second trajectory segment A3A4, and the second rotating shaft rotates on its own axis and revolves around the first rotating shaft.

[0016] Optionally, during the movement of the first rotating shaft along the first trajectory segment A1A2, the air guide plate opens to the cooling flat blowing position.

[0017] Optionally, when the first rotating shaft moves to the end of the first transition trajectory segment A2A3, the air guide plate opens to the maximum air supply position.

[0018] According to a second aspect of the present invention, an air conditioner is provided, including an indoor unit, the indoor unit including: an air guide plate; and a driving device for the air guide plate of the air conditioner as described in any of the above embodiments, wherein a first connecting rod is rotatably connected to the air guide plate via a first rotating shaft, and a second connecting rod is rotatably connected to the air guide plate via a second rotating shaft.

[0019] The driving device for the air guide plate of the air conditioner and the air conditioner provided in this disclosure can achieve the following technical effects:

[0020] When the drive wheel rotates, the first rack meshes with the first tooth, driving the first connecting rod. When the drive wheel rotates, the first drive unit meshes with the first drive mating part, driving the first connecting rod. When the drive wheel rotates, the second rack meshes with the second tooth, driving the second connecting rod. When the drive wheel rotates, the second drive unit meshes with the second drive mating part, driving the second connecting rod. Thus, the movement of the first connecting rod is not only achieved through the interaction of the first drive unit and the first drive mating part, thereby reducing wear on both. Similarly, the movement of the second connecting rod is not only achieved through the interaction of the second drive unit and the second drive mating part, thereby reducing wear on both. This improves the reliability of the operation of the first and second drive units, and ultimately enhances the movement accuracy of the air guide plate.

[0021] The transition from the engagement of the first tooth and the first rack to the engagement of the first drive unit and the first drive mating unit to drive the first link occurs in the first transition trajectory segment A2A3. Similarly, the transition from the engagement of the second tooth and the second rack to the engagement of the second drive unit and the second drive mating unit to drive the second link occurs in the second transition trajectory segment B2B3. The first transition trajectory segment A2A3 corresponds to the second transition trajectory segment B2B3. In other words, the transition from the engagement of the first tooth and the first rack to the engagement of the first drive unit and the first drive mating unit and the transition from the engagement of the second tooth and the second rack to the engagement of the second drive unit and the second drive mating unit occur at the same stage, facilitating unified control of the transition process and making it smoother. For example, the speed of the drive wheel can be reduced during the transition process.

[0022] The above general description and the description below are exemplary and illustrative only and are not intended to limit this application. Attached Figure Description

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

[0066] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0067] Combination Figures 1-27 As shown, this embodiment of the present disclosure provides a driving device for an air guide plate of an air conditioner, including a drive wheel 30, a first connecting rod 10, and a second connecting rod 20.

[0068] like Figure 5As shown, the drive wheel 30 is rotated in a controlled manner and includes a first tooth 301 and a second tooth 302; the first connecting rod 10 includes a first rack 101 for meshing with the first tooth 301 and is directly rotatably connected to the air guide plate 70 through a first rotating shaft 501; the second connecting rod 20 includes a second rack 201 for meshing with the second tooth 302 and is directly rotatably connected to the air guide plate 70 through a second rotating shaft 502.

[0069] The drive wheel 30 drives the first link 10 and the second link 20 to move, thereby driving the air guide plate 70 to move and realize the opening and closing of the air guide plate 70.

[0070] 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.

[0071] Optionally, such as Figure 6 and Figure 7 As shown, the first tooth 301 and the second tooth 302 are coaxially arranged and rotate synchronously.

[0072] 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. On the one hand, this 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 single motor.

[0073] Optionally, the first tooth 301 is a non-circular gear, and the second tooth 302 is a cylindrical gear.

[0074] 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 air guiding needs of the air conditioner.

[0075] Through the special shape and transmission characteristics of the non-circular gear, more precise speed control and position adjustment can be achieved during the movement of the air guide plate 70, making the air guiding effect of the air conditioner more ideal and improving user comfort.

[0076] Optionally, such as Figure 28As 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, a first transition trajectory segment A2A3, and a second trajectory segment A3A4 connected in sequence. The movement trajectory of the second rotating shaft 502 includes a third trajectory segment B1B2, a second transition trajectory segment B2B3, and a fourth trajectory segment B3B4 connected in sequence. 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 first transition trajectory segment A2A3 corresponds to the second transition trajectory segment B2B3, 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. When the moving shaft 501 moves along the first transition trajectory segment A2A3, the second rotating shaft 502 moves along the second transition trajectory segment B2B3. The second trajectory segment A3A4 corresponds to the fourth trajectory segment B3B4. That is, during the movement of the air guide plate 70, when the first rotating shaft 501 moves along A3A4, the second rotating shaft 502 moves along B3B4. Among them, at least one of the first trajectory segment A1A2, the second trajectory segment A3A4, the third trajectory segment B1B2, and the fourth trajectory segment B3B4 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 outlet of the air conditioner and the air guiding requirements.

[0077] The first transition trajectory segment A2A3 corresponds to the switching from the engagement of the first tooth and the first rack to the engagement of the first drive unit and the first drive mating unit. The second transition trajectory segment B2B3 corresponds to the switching from the engagement of the second tooth and the second rack to the engagement of the second drive unit and the second drive mating unit 217.

[0078] Optionally, the first transition trajectory segment A2A3 has a different shape than the first trajectory segment A1A2, which can significantly change the position of point A3, thereby changing the position of the air guide plate and achieving the expected air guiding effect of the air guide plate. And / or, the second transition trajectory segment B2B3 has a different shape than the third trajectory segment B1B2, which can significantly change the position of point B3, thereby changing the position of the air guide plate and achieving the expected air guiding effect of the air guide plate.

[0079] Shape refers to linear shapes such as curves, arcs, and straight lines. The second transition trajectory segment B2B3 has a different shape than the third trajectory segment B1B2. For example, the second transition trajectory segment B2B3 is a non-circular arc curve, while the third trajectory segment B1B2 is a circular arc.

[0080] Optionally, the first transition trajectory segment A2A3 and the second trajectory segment A3A4 have different shapes, and / or the second transition trajectory segment B2B3 and the fourth trajectory segment B3B4 have different shapes, so as to smoothly complete the switching from the meshing of the first tooth and the first rack to the engagement of the first drive part and the first drive mating part, and from the meshing of the second tooth and the second rack to the engagement of the second drive part and the second drive mating part 217, and complete the movement of the guide vane after the switching.

[0081] Optionally, the first trajectory segment A1A2, the first transition trajectory segment A2A3, and the second trajectory segment A3A4 have the same shape.

[0082] This configuration makes the movement of the first rotating shaft more stable, simplifies the control logic and structural design of the drive device for the air conditioner's air guide plate, reduces manufacturing costs and control difficulty, and also helps to ensure the stability of the air guide plate during movement.

[0083] Optionally, the first trajectory segment A1A2, the first transition trajectory segment A2A3, and the second trajectory segment A3A4 are all arc-shaped and located on the same circumference, which further ensures the coordination and consistency of the first rotating shaft movement, reduces errors and deviations during the movement process, and improves the accuracy and stability of the wind guide plate movement.

[0084] Optionally, the third trajectory segment B1B2 is an arc shape, and the second transition trajectory segment B2B3 is a non-arc shape, which can change the position of point B3 to a large extent, thereby changing the air guiding position of the air guide plate and improving the air guiding effect.

[0085] As the first rotating shaft moves along the first trajectory segment A1A2, the air guide plate opens to the cooling flat blowing position.

[0086] When the first rotating shaft moves to the end point A3 of the first transition trajectory segment A2A3 and the second rotating shaft rotates to the end point B3 of the second transition trajectory segment B2B3, the air guide plate opens to the maximum air supply position.

[0087] Optionally, both the first trajectory segment A1A2 and the third trajectory segment B1B2 are circular arcs.

[0088] 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 conditioner's air guide plate simpler, facilitating precise motion control, improving the system's reliability and stability, and also making the movement of the air guide plate 70 smoother during the initial opening phase, reducing vibration and noise during the movement process.

[0089] Optionally, the second trajectory segment A3A4 is an arc, and it is two arcs on the same circle as the first trajectory segment A1A2. The two arcs share a common point A2. This setting makes the movement of the first rotating shaft 501 more continuous and avoids abrupt changes and stuttering when moving from the first trajectory segment to the second trajectory segment.

[0090] 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 A3 along the first trajectory segment A1A2 and the first transition trajectory segment A2A3, and the second rotating shaft 502 moves from B1 to B3 along the third trajectory segment B1B2 and the second transition trajectory segment B2B3; during the process of the air guide plate 70 opening from the second position to the third position, the first rotating shaft 501 reciprocates along the second trajectory segment A3A4, and the second rotating shaft 502 moves from B2 to B3 along the fourth trajectory segment B3B4.

[0091] A fourth position may exist between the first and second positions, and a fifth position may exist between the second and third positions. During the opening process, the air guide plate 70 passes through the first, fourth, second, fifth, and third positions sequentially. For example... Figures 1 to 27 As shown, the first position is the off position, the fourth position is the cooling horizontal airflow position, the second position is the maximum airflow position, the fifth position is the wraparound airflow position, and the third position is the heating downward airflow position. Alternatively, the fourth position is the heating downward airflow position, and the third position is the cooling horizontal airflow position.

[0092] When the air guide plate 70 opens from the second position to the third position, the first rotating shaft 501 reciprocates along the second trajectory segment A3A4. 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 guide plate inside the indoor unit 80.

[0093] Optionally, such as Figure 28 As shown, the fourth trajectory segment B3B4 is a non-circular arc curve. In conjunction with the reciprocating motion of the first rotating shaft 501 along the second trajectory segment A3A4, it moves from A3 to A4 and then from A4 to A3, performing one or more cycles to realize the flipping of the air guide plate 70 from the second position to the third position.

[0094] Optionally, when the second rotating shaft 502 moves along the fourth trajectory segment B3B4, the second rotating shaft 502 rotates on its own axis and revolves around the first rotating shaft 501.

[0095] During the movement of the air guide plate 70 from the second position to the third position, the rotation center of the second rotating shaft 502 is the position of the first rotating shaft 501 corresponding to the current position of the second rotating shaft 502. Specifically, at the same moment, when the second rotating shaft 502 is at position B7, the first rotating shaft 501 is at position A7. Here, B7 is a point between B2 and B3 in the second trajectory segment B3B4, and A7 is a point between A3 and A4 in the second trajectory segment A3A4. The position of the first rotating shaft 501 is not fixed during the movement of the air guide plate 70; therefore, the position of the rotation center of the second rotating shaft 502 is also not fixed. Combined with the rotation of the second rotating shaft 502, the air guide plate 70 flips from the second position to the third position.

[0096] Optionally, when the second rotating shaft 502 moves along the fourth trajectory segment B3B4, 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.

[0097] Optionally, when the second rotating shaft 502 moves along the fourth trajectory segment B3B4, 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.

[0098] 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 B3B4, the second link 20 does not perform translational motion, but rather a combination of movement and rotation, with the instantaneous rotation centers of the points on the same plane constantly changing. This, combined with the movement of the first rotating shaft 501, enables the air guide plate 70 to move from the second position to the third position.

[0099] Optionally, such as Figure 4 , Figure 8 , Figure 14 , Figure 17 and Figure 21 As shown, the second link 20 includes a second link guide 202 and a third link guide 204. During the opening of the air guide plate 70, the second link guide 202 has a reciprocating motion, which shortens the extension distance of the second link 20, reduces the size of the second link 20, and ensures the strength of the second link 20; the third link guide 204 moves in one direction.

[0100] The third link guide 204 moves in one direction, while the second link guide 202 moves in a reciprocating motion. Through the reciprocating motion of the second link guide 202 and the one-way motion of the third link guide 204, the second link 20 can achieve a complex motion trajectory, thereby enabling the air guide plate 70 to achieve a complex motion mode during the opening process, meeting the diverse needs of the air conditioner for air guiding direction and angle under different operating conditions.

[0101] Optionally, the second link guide 202 is located between the third link guide 204 and the second rotating shaft 502. The movement trajectory of the second link 20 is realized by the movement trajectory of the second rotating shaft 502, the movement trajectory of the second link guide 202, and the movement trajectory of the third link guide 204, so as to meet the movement requirements of the air guide plate 70.

[0102] Optionally, during the process of the air guide plate 70 opening from the first position to the second position, both the second link guide 202 and the third link guide 204 move in one direction.

[0103] During the process of the air guide plate 70 opening from the first position (closed position) to the second position (maximum air supply position), both the second link guide 202 and the third link guide 204 move in one direction. This design simplifies the motion control logic of the first link 10 and the second link, facilitates precise motion control, and reduces the complexity of the control system.

[0104] Optionally, such as Figure 22 As shown, during the process of the air guide plate 70 opening from the second position to the third position, the third link guide part 204 and the second rotating shaft 502 have opposite movements or opposite movement trends, or there is a moment when the angle between the movement direction of the third link guide part 204 and the second rotating shaft 502 is greater than 90°, so that the second link 20 can be deflected at a large angle instead of translated, thereby enabling the air guide plate 70 to flip when the stroke of the second link 20 is small, so that the air guide plate 70 can switch from the second position to the third position.

[0105] Optionally, during the process of the air guide plate 70 opening from the second position to the third position, the movement trajectories of the second link guide 202 and the third link guide 204 are different, so that the second link 20 can deflect instead of translate, thereby realizing the switching of the air guide plate 70 from the second position to the third position.

[0106] like Figure 1 , Figure 4 and Figure 12As shown, the drive device for the air guide plate of the air conditioner also includes a mechanism box 6. The mechanism box 6 includes a first box cover 61 and a second box cover 62 that are arranged opposite to each other and joined together. The first box cover 61 and the second box cover 62 together define an accommodating space. The first connecting rod 10, the second connecting rod 20, and the drive wheel 30 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 box cover 61 to the second box cover 62.

[0107] The second cover 62 includes a second cover guide 621, which cooperates with the second link guide 202 to guide the movement trajectory of the second link 20, so as to drive the air guide plate 70 to move along the set trajectory.

[0108] The second cover 62 also includes a third cover guide 625, which cooperates with the third link guide 204, and the second cover guide 621 cooperates with the second link guide 202 to jointly guide the movement trajectory of the second link 20.

[0109] like Figure 4 and Figure 8 As shown, one of the second cover guide portion 621 and the second link guide portion 202 is a second guide groove 622, and the other is a second guide post 203. The second guide post 203 is adapted to the second guide groove 622, and the second guide post 203 is located in the second guide groove 622 and can slide relative to the second guide groove 622. One of the third cover guide portion 625 and the third link guide portion 204 is a third guide groove 626, and the other is a third guide post 205. The third guide post 205 is adapted to the third guide groove 626, and the third guide post 205 is located in the third guide groove 626 and can slide relative to the third guide groove 626.

[0110] The second guide groove 622 includes a first sub-guide groove 623 and a second sub-guide groove 624 that are sequentially arranged and connected along the length of the second guide groove 622. During the process of the air guide plate 70 opening from the first position to the third position, the second guide post 203 passes through the first sub-guide groove 623 and the second sub-guide groove 624 in sequence. The third guide groove 626 includes a third sub-guide groove 627, a fourth sub-guide groove 628 and a fifth sub-guide groove 629 that are sequentially arranged and connected along the length of the third guide groove 626. During the process of the air guide plate 70 opening from the first position to the third position, the third guide post 205 passes through the third sub-guide groove 627, the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence.

[0111] like Figure 2 , Figure 3 , Figure 13 , Figure 14 , Figure 16 and Figure 17As 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 B1B3. The second guide post 203 is located in the first sub-guide groove 623 and can slide unidirectionally relative to the first sub-guide groove 623. The third guide post 205 is located in the third sub-guide groove 627 and can slide unidirectionally relative to the third sub-guide groove 627. That is, the second guide post 203 cooperates with the first sub-guide groove 623, and the third guide post 205 cooperates with the third sub-guide groove 627.

[0112] like Figures 20 to 27 As shown, during the process of the air guide plate 70 opening from the second position to the third position, the movement trajectory of the second rotating shaft 502 is B3B4, which is a non-circular arc. The second guide post 203 is located in the second sub-guide groove 624 and can reciprocate relative to the second sub-guide groove 624 along the length direction of the second sub-guide groove 624. The third guide post 205 is located in the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence and can slide unidirectionally relative to the fourth sub-guide groove 628 and the fifth sub-guide groove 629. That is, the second guide post 203 cooperates with the second sub-guide groove 624, and the third guide post 205 cooperates with the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence. When the third guide post 205 cooperates with the fourth sub-guide groove 628, the third guide post 205 and the second rotating shaft 502 have opposite movements. When the third guide post 205 cooperates with the low-speed sub-guide groove, the third guide post 205 and the second rotating shaft 502 have the same direction of movement. The second sub-guide groove 624 can be arc-shaped. In this case, the second sub-guide groove 624 and the first sub-guide groove 623 are located on the same circle or different circles. The fourth sub-guide groove 628 and the fifth sub-guide groove 629 can be arc-shaped or not. The fourth sub-guide groove 628 and the fifth sub-guide groove 629 are both located on the same side of the third sub-guide groove 627.

[0113] The first cover 61 is provided with a first cover guide 611, and the first connecting rod 10 is provided with a first connecting rod guide 102. One of the first connecting rod guide 102 and the first cover guide 611 is a first guide groove 612, and the other is a first guide post 103. The first guide post 103 is adapted to the first guide groove 612. The first guide post 103 is located in the first guide groove 612 and can slide relative to the first guide groove 612 to guide the movement trajectory of the first connecting rod 10.

[0114] When the first rotating shaft 501 moves along the first trajectory segment A1A2 and the first transition trajectory segment A2A3, the first guide post 103 moves unidirectionally within the first guide groove 612. When the first rotating shaft 501 reciprocates along the second trajectory segment A3A4, the first guide post 103 reciprocates within the first guide groove 612. The number of first guide posts 103 can be one or more, and the number of first guide grooves 612 is less than or equal to the number of first guide posts 103, such that at least one first guide post 103 is provided within each first guide groove 612. When multiple first guide posts 103 are provided within the first guide groove 612, the multiple first guide posts 103 are sequentially arranged along the length direction of the first guide groove 612.

[0115] The first link 10 can perform translational motion. The motion trajectories of all points on the first link 10 are the same. The shape of the first guide groove 612 is the same as the motion trajectory of the first rotating shaft 501. That is, after translation, the motion trajectory of the first guide groove 612 and the first rotating shaft 501 can coincide.

[0116] It is understandable that the first link 10 may not need to translate, or it may deflect during the movement.

[0117] 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.

[0118] Arcs B5 and B6 are the pitch lines of the second rack; arc B7 is the pitch circle of the second tooth of the drive wheel, with center E; in the closed position of the air guide plate, the second rack and the second tooth are tangent at point B5.

[0119] Non-circular curve A5A7 is the pitch line of the first rack; non-circular curve A5A6 is the pitch line of the first tooth, with center E; in the initial position, the first rack and the first tooth are tangent at point A5.

[0120] Arc B1B2 corresponds to nodal line B5B6, and curve B2B3 is the switching process of the second tooth disengaging from the second rack and the second drive column entering the second drive slot; at the same time, the air guide plate is flipped to the maximum air supply position.

[0121] The A2A3 stage of the arc is the switching process of the first tooth disengaging from the first rack and the first drive column entering the first drive slot for driving, while simultaneously causing the air guide plate to flip to the maximum air supply position.

[0122] The B3B4 stage is the process in which the second drive column drives the second drive groove, which in turn drives the second connecting rod to move, thereby causing the air guide plate to move.

[0123] The A3A4 stage of the arc is the process in which the first drive groove drives the first drive column to move the air guide plate.

[0124] Arcs B8 and B9 represent the motion trajectory of the second guide post and also the shape of the second guide groove. The second guide post exhibits reciprocating motion in the latter part of its trajectory. Curves B10 and B11 represent the motion trajectory of the third guide post and also the shape of the third guide groove. These curves are a combination of arcs and curves. The initial portion of the third guide post's trajectory follows the same motion trend as the second rotating axis. The middle and later portions of the third guide post's trajectory move in the opposite direction to the second rotating axis. Finally, the final portion of the third guide post's trajectory follows the same motion trend as the second rotating axis.

[0125] 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.

[0126] Air guide vane 70 changes from closed position to cooling flat-blowing position to maximum airflow position:

[0127] The first rotating shaft 501 moves from A1 along the circular arc A1A3 to A2; the second rotating shaft 502 moves from B1 along the circular arc B1B2 to B2, and then moves along the non-circular curve B2B3 to B3.

[0128] 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.

[0129] The first rotating shaft 501 reciprocates along the arc A3A4 starting from A3; the second rotating shaft 502 moves along the curve B3B4 to B4 starting from B3, where the curve B3B4 is not a circular arc, and its instantaneous rotation center, the first rotating shaft 501, reciprocates along the arc A3A4.

[0130] 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.

[0131] The first cover 61 and the second cover 62 are arranged opposite to each other. The first limiting part and the first limiting mating part of the first cover 61 can restrict the movement of the second link 20 toward the first cover 61. The second limiting part and the second limiting mating part of the second cover 62 can restrict the movement of the second link 20 toward the second cover 62. This achieves accurate limiting of the second link 20 in the direction of the line connecting the first cover 61 and the second cover 62. Moreover, the limiting of the second link 20 is not achieved by means of the first link 10, thus avoiding the second link 20 affecting the movement of the first link 10.

[0132] 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.

[0133] Alternatively, the first limiting engagement part includes a limiting area formed by the second link 20 protruding toward the first cover 61, which reduces the distance between the limiting area and the first cover 61, thereby facilitating the contact and engagement between the first limiting part and the first limiting engagement part. Moreover, the limiting area can also enhance the strength of the second link 20. The first limiting part includes a first limiting post provided on the first cover 61, which abuts against the limiting area and can move relative to the limiting area.

[0134] 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.

[0135] Optionally, the limiting area is planar to ensure that the first limiting post is always in contact with the limiting area during the movement.

[0136] The second lid guide 621 and / or the third lid guide 625 can be used as the second limiting part, that is, the second limiting part includes the second lid guide 621 and / or the third lid guide 625. Correspondingly, the second limiting part includes the second lid guide 621, and the second limiting mating part includes the second link 20 guide part and the third link guide part. This simplifies the structure of the second lid 62 and the second link 20.

[0137] For example, the second limiting post includes a second guide post 203 and / or a third guide post 205, and the second limiting groove includes a second guide groove 622 and / or a third guide groove 626.

[0138] Optionally, such as Figure 7 As shown, the drive device for the air guide plate of the air conditioner also includes a third limiting part, which is supported between the first link 10 and the second link 20.

[0139] 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.

[0140] like Figures 6 to 11As shown, 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.

[0141] 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.

[0142] 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.

[0143] Optionally, the first tooth 301 extends circumferentially along the drive wheel 30 and is non-circular.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] Optionally, the first drive groove 312 has an open end that extends through the edge of the drive wheel 30 or the first connecting rod 10, and the first drive column 105 is inserted into or removed from the first drive groove 312 through the open end of the first drive groove 312.

[0148] 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 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 of the first drive groove 312.

[0149] like Figure 7 As shown, the first drive groove 312 is provided on the drive wheel 30, and the open end of the first drive groove 312 passes through the edge of the drive wheel 30.

[0150] Optionally, if the first drive section 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 section 301 and extends circumferentially along the drive wheel 30.

[0151] 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 distance 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 A3A4.

[0152] The first drive groove 312 also includes a second groove segment 314, one end of which forms the opening end of the first drive groove 312, and the other end of which 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 engages with the second groove segment 314, 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 engages with the first groove segment 313, provided that the drive wheel 30 rotates through the same angle.

[0153] 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.

[0154] 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.

[0155] Optionally, such as Figure 10 and Figure 11 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] Optionally, such as Figure 8 and Figure 9 As shown, the second rack 201 is a non-linear rack.

[0161] 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.

[0162] 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.

[0163] During the process of the air guide plate 70 opening from the first position to the third position, the drive wheel 30 rotates in one direction, and the first rotating shaft 501 has reciprocating motion. When the drive wheel 30 rotates in one direction, it is difficult to achieve reciprocating motion by using a gear and rack drive. Therefore, when the first drive part 303 is set to cooperate with the first drive mating part 104, the first rotating shaft 501 has reciprocating motion.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] Optionally, such as Figure 10 and Figure 11 As shown, the first rack 101 is a non-linear rack.

[0168] 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.

[0169] The second link includes a second rack and a second drive engagement part 217. The second rack and the second tooth can mesh with each other, and the second drive part and the second drive engagement part 217 can slide or roll together. The second link is movably connected to the air guide plate. The first rack corresponds to the second rack, and the first drive engagement part corresponds to the second drive engagement part 217.

[0170] The driving force for the movement of the first link comes from the engagement of the first tooth with the first rack, and the driving force for the movement of the second link comes from the engagement of the second tooth with the second rack; the driving force for the movement of the first link comes from the engagement of the first driving part with the first driving mating part, and the driving force for the movement of the second link comes from the engagement of the second driving part with the second driving mating part 217.

[0171] The drive wheel includes a first surface, a second surface, and a circumferential sidewall 316, with the second surface being disposed opposite to the first surface; the circumferential sidewall 316 is disposed between the first surface and the second surface; a first drive part is disposed on the first surface, a second drive part is disposed on the second surface, a first tooth part and a second tooth part are disposed on the circumferential sidewall 316 and are arranged sequentially along the direction from the first surface to the second surface, and both the first surface and the second surface extend circumferentially along the drive wheel.

[0172] This configuration allows the first tooth and the first drive unit to easily engage with the first link, and the second tooth and the second drive unit to easily engage with the second link, ensuring that the movements of the first link and the second link do not interfere with each other.

[0173] The second rack and the second drive engagement part 217 are arranged sequentially along the length of the second connecting rod, so that the meshing of the second rack and the second tooth and the engagement of the second drive part and the second drive engagement part 217 can occur sequentially.

[0174] Optionally, one of the second driving part and the second driving mating part 217 includes a second driving post, and the other includes a second driving groove, wherein the second driving post and the second driving groove are capable of sliding or rolling mating.

[0175] Optionally, the first driving part includes a first driving groove, and the second driving part includes a second driving column; or, the first driving part includes a first driving column, and the second driving part includes a second driving groove.

[0176] The first drive unit and the second drive unit are either in the form of a column or both are in the form of a groove. This arrangement can avoid the drive wheel being too large, making the drive wheel structure more compact, and also making the drive device used for the air guide plate of the air conditioner more compact.

[0177] Optionally, the second drive slot includes a first sub-drive slot 215 and a second sub-drive slot 216, and the second drive column includes a first sub-drive column 317 and a second sub-drive column 318. During the opening of the air guide plate, the first sub-drive column 317 and the second drive column 318 enter the first sub-drive slot 215 and the second drive slot 216 in sequence.

[0178] The first sub-drive column 317 engages with the first sub-drive slot 215, and the second sub-drive column 318 engages with the second sub-drive slot 216. During the opening of the air guide plate, the first sub-drive column 317 enters the first sub-drive slot 215 first, followed by the second sub-drive column 318 entering the second sub-drive slot 216, or the second sub-drive column 318 enters the second sub-drive slot 216 first, followed by the first sub-drive column 317 entering the first sub-drive slot 215. This ensures smoother movement of the drive device for the air guide plate of the air conditioner. It also prevents the first sub-drive column 317 and the second sub-drive column 318 from simultaneously entering their corresponding sub-drive slots, which could cause jamming in the drive device for the air guide plate of the air conditioner.

[0179] Optionally, the central angle formed by the first sub-drive column 317 and the second sub-drive column 318 is greater than 120°, that is, the central angle formed by the line connecting the first sub-drive column 317 to the center of the drive wheel and the line connecting the second sub-drive column 318 to the center of the drive wheel is greater than 120°. This means that the first sub-drive column 317 and the second sub-drive column 318 are distributed over a wider range on the drive wheel, which makes the movement of the second link more stable.

[0180] Optionally, the distances between the first sub-drive column 317 and the second sub-drive column 318 and the drive wheel axis are not equal.

[0181] This setting optimizes the torque balance during the drive process, making the drive wheel rotate more smoothly, reducing vibration and noise, and improving the operating efficiency and reliability of the drive device used for the air deflector of the air conditioner.

[0182] Optionally, the second sub-drive slot 216 is located inside the first sub-drive slot 215.

[0183] This design allows for a reduction in the size of the second link, making better use of its space.

[0184] Both the first sub-drive slot 215 and the second sub-drive slot 216 have open ends, which face the position of the drive wheel when the second tooth disengages from the second rack, so that the first sub-drive pin 317 and the second sub-drive pin 318 can enter the first sub-drive slot 215 and the second sub-drive slot 216 respectively from the open ends of the first sub-drive slot 215 and the second sub-drive slot 216.

[0185] The first sub-drive slot 215 includes straight lines and / or curves, and the second sub-drive slot 216 includes straight lines and / or curves. The shapes of the first sub-drive slot 215 and the second sub-drive slot 216 must meet the requirements for the motion trajectory of the second link.

[0186] The mechanism box is provided with a second guide part, and the second link is provided with a second guide mating part. The second guide part and the second guide mating part cooperate to guide the movement trajectory of the second link. There are multiple second guide mating parts. At least one of the multiple second guide mating parts is provided on the second rack, and at least one is provided on the second drive mating part 217, so that the guiding force from the mechanism box on each position of the second link is uniform, thereby guiding the second link to move smoothly.

[0187] The plurality of second guide parts include a second cover guide part and a third cover guide part, and the plurality of second guide mating parts include a second guide post and a third link guide part.

[0188] The rotation axis of the drive wheel 30 is set perpendicular to the first surface 304 and the second surface 305.

[0189] The first link 10 and the second link are both 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.

[0190] One of the mechanism box 6 and the first link 10 is provided with a first positioning part, and the other of the mechanism box 6 and the first link 10 is provided with a first positioning engagement part and a second positioning engagement part. The first positioning engagement part and the second positioning engagement part are arranged sequentially along the direction from the first box cover 61 to the second box cover 62. The first positioning part is located between the first positioning engagement part and the second positioning engagement part to restrict the movement of the first link 10 in the direction of the line connecting the first box cover 61 and the second box cover 62.

[0191] The first positioning engagement part and the second positioning engagement part are arranged sequentially along the direction from the first cover 61 to the second cover 62. The first positioning part is located between the first positioning engagement part and the second positioning engagement part. The engagement of the first positioning part with the first positioning engagement part restricts the movement of the first connecting rod 10 toward the first cover 61, and the engagement of the second positioning part with the second positioning engagement part restricts the movement of the second connecting rod 20 toward the second cover 62, thereby restricting the movement of the first connecting rod 10 in the direction of the line connecting the first cover 61 and the second cover 62. Moreover, the limiting of the first connecting rod 10 is not achieved by means of the second connecting rod 20, avoiding the interaction force between the first connecting rod 10 and the second connecting rod 20 as in related technologies, thereby ensuring the movement accuracy of the air guide plate 70.

[0192] Optionally, one of the mechanism box 6 and the first connecting rod 10 is provided with a positioning rib 111, and the other of the mechanism box 6 and the first connecting rod 10 is provided with a positioning groove 617. The positioning groove 617 includes a first groove wall and a second groove wall. The first groove wall and the second groove wall are arranged opposite to each other and are arranged sequentially along the direction from the first box cover 61 to the second box cover 62. The positioning rib 111 is located between the first groove wall and the second groove wall. The first positioning part includes the positioning rib 111, the first positioning mating part includes the first groove wall, and the second positioning mating part includes the second groove wall.

[0193] Optionally, one of the positioning grooves 617 in the mechanism box 6 and the first connecting rod 10 is also provided with a positioning protrusion 615, and a positioning wheel 616 is fitted onto the positioning protrusion 615, with the positioning groove 617 located on the positioning wheel 616.

[0194] Optionally, the positioning rib 111 is made of a wear-resistant material to reduce wear on the positioning rib 111.

[0195] Optionally, there are multiple positioning slots 617, which are arranged sequentially along the direction from the retracted position to the extended position. During the movement of the first connecting rod 10, the positioning rib 111 is located in at least one positioning slot 617.

[0196] Optionally, the travel restriction area 618 is located in the first cover 61.

[0197] 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 618. 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. On the other hand, it can also enhance the strength of the first box cover 61.

[0198] Optionally, the first link 10 further includes a first link body 114, which includes a first rack 101; the drive engagement structure 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.

[0199] During the movement of the first link 10, the connecting rod 109 is located within the travel restriction area 618 and moves relative to the travel restriction area 618, so that the travel restriction area 618 defines the movement area of ​​the drive engagement structure.

[0200] The limiting effect of the travel restriction area 618 on the drive engagement structure is achieved by limiting the connecting rod 109 through the travel restriction area 618, rather than by limiting the first drive engagement part 104 through the travel restriction area 618. This ensures that the limiting effect of the travel restriction area 618 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.

[0201] Optionally, the first box cover 61, the connecting rod 109, and the first rod body 114 are arranged sequentially.

[0202] On the one hand, the connecting rod 109 is closer to the first cover 61, and thus closer to the travel restriction area 618, which facilitates the engagement of the connecting rod 109 with the travel restriction area 618. On the other hand, the first drive engagement part 104 and the first rod body 114 are both located on the side of the connecting rod 109 away from the first cover 61, which makes the first drive engagement part 104 and the first rack 101 closer to the drive wheel 30, which facilitates the engagement of the drive wheel 30 with the first drive engagement part 104 and the first rack 101.

[0203] Optionally, the second tooth 302 extends circumferentially along the drive wheel 30 and is either annular or non-annular.

[0204] 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.

[0205] When the second link 20 is partially driven by the second tooth 302, the second tooth 302 is non-circular. In this case, the second surface 305 is provided with a second driving part for driving the second link 20. The second driving part includes a second driving groove or a second driving post. The second link 20 is provided with a second driving engagement part 217. The second driving part and the second driving engagement part 217 slide or roll together. One of the second driving part and the second driving engagement part 217 is a second driving groove, and the other is a second driving post. The second driving engagement part 217 and the second rack 201 are arranged sequentially along the length of the second link 20. During the opening of the air guide plate 70, the meshing of the second tooth 302 with the second rack 201 and the engagement of the second driving part with the second driving engagement part 217 occur sequentially, or the engagement of the second driving part with the second driving engagement part 217 and the meshing of the second tooth 302 with the second rack 201 occur sequentially.

[0206] Optionally, when the first driving part 303 is the first driving post 105, the first driving post 105 protrudes from the first tooth part 301 to facilitate the engagement of the first driving post 105 with the first driving groove 312.

[0207] 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.

[0208] The second surface 305 is provided with a second driving part for driving the second connecting rod 20. The second driving part includes a second driving groove or a second driving column.

[0209] The second link 20 is provided with a second drive engagement part 217. The second drive part and the second drive engagement part 217 are in sliding or rolling engagement. One of the second drive part and the second drive engagement part 217 includes a second drive post, and the other includes a second drive groove. During the movement of the second link 20, part of the stroke is driven by the meshing of the second tooth 302 and the second rack 201, and the other part of the stroke is driven by the engagement of the second drive part and the second drive engagement part 217. By providing the second drive part and the second drive engagement part 217, the movement trajectory of the second link 20 can be changed, thereby reducing the movement stroke of the second link 20.

[0210] Optionally, the drive wheel 30 includes a partition plate 311, which is used to separate the first link 10 and the second link 20. The partition plate can restrict the movement of the first link 10 toward the drive wheel and also restrict the movement of the second link 20 toward the drive wheel, 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).

[0211] Optionally, such as Figures 6 to 11As shown, the surface of the first link 10 facing the drive wheel 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 wheel 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.

[0212] The 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 located between the first connecting rod 10 and the second connecting rod 20.

[0213] 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.

[0214] When the first tooth disengages from the first rack and the second tooth disengages from the second rack, the first drive unit engages with the first drive engagement unit, and the second drive unit engages with the second drive engagement unit 217 to restrict the movement of the first link and the second link in the thickness direction of the mechanism box.
