Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to a drive assembly for an air conditioning 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 rack and pinion assembly is disclosed in related technology, including a first rack structure and a second rack structure. One end of the first rack structure has a rotating shaft for connecting to a rotating seat of an air guide plate, allowing the air guide plate to rotate around the rotating shaft. One end of the second rack structure has an upwardly bent portion with a rotating shaft, allowing it to rotate within and move along the directional track groove of the air guide plate. The first and second rack structures are arranged side-by-side, with the tooth length of the second rack structure being greater than that of the first rack structure. During synchronous motion, the first and second rack structures jointly drive the air guide plate, with the current plane of the air guide plate parallel to its initial plane. During differential motion, the first and second rack structures move at different speeds, causing the air guide plate to rotate around the rotating shaft. In a second mode, the first rack structure extends forward a second predetermined distance and then comes to a stop, while the second rack structure extends forward a length greater than the second predetermined distance, placing the air guide plate in an upward-opening state, suitable for cooling.

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

[0005] After the first rack structure stops moving, the second rack structure continues to extend along a straight line, resulting in a long extension distance for the second rack structure and a large space occupied by the entire drive structure.

[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.

[0058] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0063] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0064] 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.

[0065] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0066] Combination Figures 1-23 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.

[0067] like Figure 13 As shown, the drive wheel 30 is rotated in a controlled manner and includes a first tooth 301 and a second tooth 302; the first connecting rod 10 includes a first rack 101 for meshing with the first tooth 301 and is directly rotatably connected to the air guide plate 70 through a first rotating shaft 501; the second connecting rod 20 includes a second rack 201 for meshing with the second tooth 302 and is directly rotatably connected to the air guide plate 70 through a second rotating shaft 502.

[0068] 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.

[0069] 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.

[0070] Optionally, such as Figure 20 and Figure 23 As shown, the first tooth 301 and the second tooth 302 are coaxially arranged and rotate synchronously.

[0071] 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.

[0072] Optionally, the first tooth 301 is a non-circular gear, and the second tooth 302 is a cylindrical gear.

[0073] 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.

[0074] 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.

[0075] 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 40, which meshes with a cylindrical gear. The cylindrical gear is fixedly connected to a non-circular gear. The motor 407 drives the reduction gear 40 to rotate, which in turn drives the cylindrical gear to rotate. The non-circular gear rotates with the cylindrical gear.

[0076] like Figure 15 As shown, the reduction gear 40 is a cylindrical gear and the radius of the reduction gear 40 is smaller than the radius of the second tooth 302.

[0077] Optionally, such as Figures 24 to 27 As shown, during the opening of the air guide plate 70, the movement trajectory of the first rotating shaft 501 includes the first trajectory segment A1A2 and the second trajectory segment A2A3. The movement trajectory of the second rotating shaft 502 includes the connected third trajectory segment B1B2, the transition trajectory segment B2B4, and the fourth trajectory segment B4B5. 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 movement trajectory of the second rotating shaft also includes the transition trajectory segment B2B4. The transition trajectory segment B2B4 corresponds to the second trajectory segment A2A3. That is, 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 B2B4. When the air guide plate is closed, the first rotating shaft is located at point A1 and the second rotating shaft is located at point B1; as the air guide plate is opened, when the first rotating shaft is located at point A2, the second rotating shaft is located at point B2, and when the first rotating shaft is located at point A3, the second rotating shaft is located at point B4.

[0078] A transitional trajectory segment B2B4 is added between the third trajectory segment B1B2 and the fourth trajectory segment B4B5. While the second rotating shaft moves along the transitional trajectory segment B2B4, the first rotating shaft moves along the second trajectory segment A2A3. That is, the first rotating shaft continues to adjust its position. When the first rotating shaft reaches point A3, the second rotating shaft rotates around point A3 (the end point of the second trajectory segment A2A3). After the first rotating shaft adjusts to A3, the second rotating shaft adjusts to B4 accordingly, and then rotates around the first rotating shaft again, causing the air guide plate to begin flipping. By changing the flipping position of the air guide plate, a more ideal air guiding effect is achieved.

[0079] Optionally, both the first trajectory segment A1A2 and the third trajectory segment B1B2 are circular arcs.

[0080] 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.

[0081] Optionally, the second trajectory segment A2A3 is an arc shape, and it is one of two arcs on the same circle as the first trajectory segment A1A2. That is, the second trajectory segment A2A3 and the first trajectory segment A1A2 are located on the same circumference, and the two arcs share a common point A2. This setting makes the movement of the first rotating shaft 501 more continuous and avoids sudden changes and stuttering when moving from the first trajectory segment to the second trajectory segment.

[0082] 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 second trajectory segment A2A3, and the second rotating shaft 502 moves from B1 to B4 along the third trajectory segment B1B2 and the transition trajectory segment B2B4; during the process of the air guide plate 70 opening from the second position to the third position, the first connecting rod is stationary, the first rotating shaft is always located at A3, and the second rotating shaft 502 rotates around point A3.

[0083] 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 23 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.

[0084] When the air guide plate 70 is opened from the second position to the third position, the first connecting rod is stationary, the first rotating shaft is always located at A3, and the second rotating shaft rotates around point A3.

[0085] Optionally, the second link 20 includes a second link guide 202.

[0086] like Figure 1 , Figure 4 and Figure 8As 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 40 are all located within the accommodating space. The first connecting rod 10 and the second connecting rod 20 are arranged sequentially along the direction from the first cover 61 to the second cover 62.

[0087] 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.

[0088] like Figure 3 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.

[0089] like Figure 2 As shown, the first cover 61 is provided with a first cover guide portion, and the first connecting rod 10 is provided with a first connecting rod guide portion. One of the first connecting rod guide portion and the first cover guide portion 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.

[0090] The number of first guide posts 103 is 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 in the first guide groove 612. When multiple first guide posts 103 are provided in the first guide groove 612, the multiple first guide posts 103 are arranged sequentially along the length direction of the first guide groove 612.

[0091] 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.

[0092] It is understandable that the first link 10 may not undergo translational motion, or it may deflect during the motion.

[0093] like Figures 24 to 26As shown, in the closed position of the air guide plate 70, 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 their centers at A0. B1B2 are also arc-shaped, with their centers at B0. Figure 26 As shown, the second tooth 302 has a pitch line of circle Q7 with center E. The pitch circle of the first tooth 301 is a non-circular curve A4A6. The pitch line of the second rack 201 is B6B10, and the non-circular curve A4A5 is the pitch line of the first rack 101. Non-circular curves A4A6 and A4A5 are tangent at point A4. Pitch line B4B10 is tangent to the initial position of circle Q7 (when the air guide plate 70 is in the closed position) at point B6.

[0094] Optionally, the pitch line of the second rack includes connected arcuate and non-arc segments.

[0095] The pitch line of the second rack includes curved and non-curved segments. This design allows the air guide plate to switch between different air delivery modes more flexibly during movement, thus realizing multiple positions of the air guide plate and improving the diversity and adaptability of air delivery.

[0096] Optionally, the non-arc segment includes a straight segment, which simplifies the pitch line of the second rack, thereby simplifying the motion trajectory of the second link.

[0097] Optionally, the arc segment includes a circular arc segment, which simplifies the pitch line of the second rack, thereby simplifying the motion trajectory of the second link.

[0098] Optionally, the arc segment includes a first type of circular arc segment, and the second tooth is a cylindrical gear, wherein the radius of the first type of circular arc segment is the same as the radius of the pitch circle of the second tooth.

[0099] Optionally, the arc segment includes a second type of circular arc segment, the radius of which is different from the radius of the pitch circle of the second tooth.

[0100] Optionally, there are multiple non-arc segments, with the first type of circular arc segment connecting two adjacent non-arc segments.

[0101] Optionally, the pitch line of the second rack includes a second type of arc segment B6B7, a first type of arc segment B7B21, a non-arc segment B21B8, a first type of arc segment B8B31, a non-arc segment B31B9, a first type of arc segment B9B41, and a second type of arc segment B41B10 arranged sequentially.

[0102] Optionally, when the air guide plate is opened to the designated position, there are multiple tangent points between the second tooth and the second rack on the second rack.

[0103] Optionally, the motion trajectory of the second rotating shaft includes a third trajectory segment B1B2, which corresponds to the second type of arc segment B6B7, and the third trajectory segment B1B2 is arc-shaped; and / or the motion trajectory of the second rotating shaft includes a fourth trajectory segment B4B5, which corresponds to the second type of arc segment B41B10, and the fourth trajectory segment B4B5 is arc-shaped.

[0104] Optionally, the motion trajectory of the second rotating shaft includes a first sub-transition trajectory segment B2B3, which corresponds to the non-arc segment B21B8, and the first sub-trajectory segment B2B3 is a non-arc segment; and / or the second connecting rod is directly rotatably connected to the air guide plate through the second rotating shaft, and the motion trajectory of the second rotating shaft includes a second sub-transition trajectory segment B3B4, which corresponds to the non-arc segment B31B9, and the second sub-transition trajectory segment B3B4 is a non-arc segment.

[0105] The pitch lines of the second rack include, in sequence, second type arc segment B6B7, first type arc segment B7B21, non-arc segment B21B8, first type arc segment B8B31, non-arc segment B31B9, first type arc segment B9B41, and second type arc segment B41B10.

[0106] In the initial position (when the air guide plate is in the closed position), the second rack is tangent to the drive wheel at point B6. The location of the tangent point between the second rack and the drive wheel passes through the arc B6B7, the straight line B21B8, the straight line B31B9, and the arc B41B10 in sequence on the pitch line of the second rack.

[0107] Non-circular curve A4A5 is the pitch curve of the first rack; non-circular curve A4A6 is the pitch circle of the first tooth, with center E. In the initial position, the first rack is tangent to the drive wheel at point A4.

[0108] The third trajectory segment B1B2 corresponds to B6B7 on the pitch line. That is, when the second rotating shaft moves along B1B2, the second tooth meshes with the part on the second rack corresponding to B6B7. The first sub-transition segment B2B3 corresponds to B21B8 on the pitch line, the second sub-transition segment B3B4 corresponds to B31B9 on the pitch line, and the fourth trajectory segment B4B5 corresponds to B41B10 on the pitch line.

[0109] On the pitch line, B7B21, B8B31, and B9B41 are arcs on the same circle as circle Q7. That is, the radius of the circle containing B7B21, B8B31, and B9B41 is the same as the radius of Q7. When the second rack is tangent to circle Q7 at positions B7, B8, and B9 respectively, B7B21, B8B31, and B9B41 coincide with circle Q7.

[0110] B211, B311, and B411 are points on the pitch circle Q7 of the second tooth, corresponding to points B21, B31, and B41 on the pitch line of the second rack, respectively. For example, if the tangent point is at B21, then point B211 on the drive wheel meshes with the second rack. B211 is an absolute position, meaning it does not rotate with the drive wheel.

[0111] The arc B411B101 is the position of B41B10 on the second rack pitch line when the second rack moves through multiple changes in the position of the tangent point and the tangent point becomes B41 (B411).

[0112] After that, point B41 moves along the arc B411B11, and all points on the second rack move along the same trajectory. At this time, the arc B411B11 and the fourth trajectory segment B4B5 are the same in size and shape, but different in position.

[0113] The pitch line A4A5 of the first rack corresponds to the pitch circle A4A6 of the first tooth, and the motion trajectory of the first rotating shaft is the first trajectory segment A1A2.

[0114] When the motion trajectory of the first rotating shaft is the second trajectory segment A2A3, the first rack and the drive wheel no longer mesh and drive each other, and the drive part drives the drive part to move.

[0115] The pitch lines B7B21, B8B31, and B9B41 of the second rack all coincide with circle Q7, causing the tangent point between the second tooth and the second rack to jump along these pitch lines. This reduces the rotation of the drive wheel and thus changes the tangent point. When the tangent point between the second tooth and the second rack switches from B7 to B21, or when the second rotating shaft moves to point B2, all points on the pitch line of the second rack between B7 and B21 are tangent points between the second tooth and the second rack. At this point, there are more than two tangent points. Without the drive wheel rotating, the tangent point switches from B7 to B21. Then, the tangent point continuously changes from B7 to B21 via the straight line B21B8, then from B8 to B31, then via the straight line B31B9, the tangent point continuously changes to B9, and then from B9 to B41.

[0116] When the second rotating shaft moves along B1B2, the second connecting rod rotates in an arc around point B0. At this time, the speed of each point on the second connecting rod is the same, and the trajectory of each point is an arc rotating around B0.

[0117] During the stage when the second rotating axis moves along B2B5, the second link is in translational motion and does not rotate. At this time, the velocity of each point on the second link is the same, and the shape and size of the trajectory of each point on the second link are the same as those of B2B5.

[0118] Although the pitch lines A4A5 and A4A6 of the first rack are curved and non-circular arcs with no fixed center, they have fixed centers of rotation, namely A0 and E.

[0119] Circle Q7 is concentric with non-circular curve A4A6, and its rotation center is E; the rotation center of non-circular arc curve A4A5 and circular arc A1A2 is A0.

[0120] Optionally, when the second rotating shaft moves along the transition trajectory segment B2B4, the rotation direction of the drive wheel is opposite to the direction of the motion trajectory of the tangent point on the pitch circle of the second tooth.

[0121] like Figure 26 In the process, the drive wheel rotates counterclockwise, and the tangent point on the pitch circle of the second tooth moves clockwise along B6, B211, B311, and B411, thereby realizing the drive of the second tooth on the second rack.

[0122] Optionally, the line connecting the end point B4 of the transition trajectory segment B2B4 and the end point A3 of the second trajectory segment A2A3 is A3B4, the point on the pitch circle of the second tooth corresponding to the starting point B4 of the fourth trajectory segment B4B5 is B411, the center of the second tooth is E, and A3B4∥B411E.

[0123] The transition trajectory segment B2B4 includes the connected first sub-transition trajectory segment B2B3 and the second sub-transition trajectory segment B2B4. When the second rotating shaft moves along the third trajectory segment B1B2, the tangent point between the second tooth and the second rack is located at point B6 on the gear pitch circle. The angle between the tangents of B2B3 and B6 (the tangent at point B6 on circle Q7) is smaller than the angle between the tangents of B3B4 and B6 (the tangent at point B6 on circle Q7). That is, moving B2B3 makes B2 coincide with point B6, and moving B3B4 makes B4 coincide with point B6. After the movement, the angle between the tangents of B2B3 and point B6 is smaller than the angle between the tangents of B3B4 and point B6. This makes the rotation direction of the drive wheel opposite to the movement trajectory direction of the tangent point on the pitch circle of the second tooth when the second rotating shaft moves along the transition trajectory segment B2B4, thereby realizing the drive of the second tooth on the second rack.

[0124] Optionally, the transition trajectory segment B2B4 is a polygonal line, such as... Figure 26 As shown, the first sub-transition trajectory segment B2B3 and the second sub-transition trajectory segment B2B4 are both straight lines and do not overlap, making B2B4 a polygonal line.

[0125] It is understandable that the transition trajectory segment B2B4 may not be a polygonal line; for example, it could be an arc or a non-circular curve. The shape of B2B3 is the same as that of B21B8, and the shape of B3B4 is the same as that of B31B9. When the shapes of B2B3 and B3B4 change, the shapes of B21B8 and B31B9 also change accordingly.

[0126] Optionally, the transition trajectory segment B2B4 is non-smoothly connected to the third trajectory segment B1B2, and the transition trajectory segment B2B4 is non-smoothly connected to the fourth trajectory segment B4B5.

[0127] When the air guide plate moves to the maximum air supply position during the opening process, the second rotating shaft begins to move along the fourth trajectory segment B4B5.

[0128] like Figure 27 As shown, if the transition trajectory segment B2B4 does not exist, the second rack in segment B2B5 only performs translational motion without rotation. Therefore, when the second rotation axis is at position B2, the tangent point between the second tooth and the second rack is point B6, and the trajectory of the second rack is B6B11-1. The corresponding rotation trajectory of the air guide plate is B2B11-11, not rotation around point A2. Therefore, the ideal air delivery position cannot be achieved. If it could rotate around point A2, it would be possible. However, the second rack cannot rotate around A2.

[0129] A3B4 is parallel to B411E; B6E is parallel to B2B11-11, meaning the second rack performs translational motion but does not rotate.

[0130] A3B4 is parallel to B411E so that the trajectory of the second rack tangent point is the same as the trajectory of point B4, that is, translation without deflection.

[0131] 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.

[0132] The first lid 61 is provided with a first limiting part 613, and the second lid 62 is provided with a second limiting part; the second connecting rod 20 is provided with a first limiting engagement part 208 that cooperates with the first limiting part 613 and a second limiting engagement part that cooperates with the second limiting part, so as to restrict the movement of the second connecting rod 20 in the direction of the line connecting the first lid 61 and the second lid 62.

[0133] The first lid 61 and the second lid 62 are arranged opposite to each other. The first limiting part 613 and the first limiting mating part 208 of the first lid 61 can restrict the movement of the second link 20 toward the first lid 61. The second limiting part and the second limiting mating part of the second lid 62 can restrict the movement of the second link 20 toward the second lid 62. This achieves accurate limiting of the second link 20 in the direction of the line connecting the first lid 61 and the second lid 62. Moreover, the limiting of the second link 20 is not achieved by means of the first link 10, thus avoiding the second link 20 affecting the movement of the first link 10.

[0134] Optionally, one of the first limiting part 613 and the first limiting mating part 208 includes a first limiting groove 614, and the other includes a first limiting post 209. The first limiting post 209 is located in the first limiting groove and can move relative to the first limiting groove.

[0135] The cooperation of the first limiting groove and the first limiting post 209 can more accurately limit the range of motion of the second link 20, further improving the accuracy of motion control.

[0136] Optionally, one of the second limiting part and the second limiting mating part includes a second guide groove, and the other includes a second guide post, the second guide post being located in the second guide groove and capable of moving relative to the second guide groove.

[0137] Optionally, there may be multiple second guide grooves, and the number of second guide posts may be equal to and correspond one-to-one with the number of second guide grooves, and the multiple second guide grooves may have the same shape.

[0138] The drive wheel 30 also includes a drive part 303; the first connecting rod 10 also includes a drive engagement part 104, the drive part 303 and the 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 drive part 303 and the drive engagement part 104 occur sequentially, or the engagement of the drive part 303 and the drive engagement part 104, and the meshing of the first rack 101 and the first tooth 301 occur sequentially.

[0139] 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 drive part 303 slides or rolls with the drive mating part 104, driving the first connecting rod 10 to move. Alternatively, the drive part 303 slides or rolls with the 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.

[0140] 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 on the column and slot engagement. Moreover, the engagement between the first rack 101 and the first tooth 301, and the engagement between the drive part 303 and the drive engagement part 104, or the engagement between the drive part 303 and the drive engagement part 104 and the engagement between the first rack 101 and the first tooth 301, can easily change the motion parameters of the first connecting rod 10, such as the motion trajectory or the motion speed, thereby realizing multiple air guiding positions of the air guide plate 70.

[0141] Optionally, such as Figure 10 , Figure 20and Figure 23 As shown, the drive wheel 30 includes a first surface 304 and a second surface 305 disposed opposite to each other, and the first tooth 301 and the drive part 303 are both disposed on the first surface 304.

[0142] 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.

[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 and the first rack 101 disengage 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 drive part 303 and the drive mating part 104.

[0145] Optionally, one of the drive unit 303 and the drive mating unit 104 includes a drive column 105, and the other includes a drive groove 312 adapted to the drive column 105.

[0146] When the drive unit 303 engages with the drive mating part 104, the drive column 105 is located in the drive groove 312 and can slide or roll relative to the drive groove 312, thereby realizing the drive unit 303 driving the drive mating part 104, that is, realizing the drive wheel 30 driving the first connecting rod 10 to move.

[0147] Optionally, the 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 drive column 105 is inserted into or removed from the drive groove 312 through the open end 315 of the drive groove 312.

[0148] When the drive post 105 is not engaged with the drive groove 312, the drive post 105 is located outside the drive groove 312. When the drive post 105 is engaged with the drive groove 312, the drive post 105 is inserted into the drive groove 312 through the open end 315 of the drive groove 312. When the drive post 105 is no longer engaged with the drive groove 312, the drive post 105 is dislodged from the drive groove 312 through the open end 315 of the drive groove 312.

[0149] like Figure 10 As shown, the drive groove 312 is provided on the drive wheel 30, and the open end 315 of the drive groove 312 passes through the edge of the drive wheel 30.

[0150] Optionally, if the drive unit 303 includes a drive groove 312, the 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.

[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 E 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 A2A3.

[0152] The drive groove 312 also includes a second groove segment 314, one end of which forms the opening end 315 of the 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 drive column 105 engages with the second groove segment 314, the travel of the first connecting rod 10 is greater than the travel of the first connecting rod 10 when the drive column 105 engages with the first groove segment 313, provided that the drive wheel 30 has rotated through the same angle.

[0153] Optionally, the first rack 101 and the 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 drive part 303 with the drive mating part 104 occur sequentially, or the engagement of the drive part 303 with the drive mating part 104 and the engagement of the first tooth 301 with the first rack 101 occur sequentially.

[0155] Optionally, such as Figure 7 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 drive engagement part 104 is provided on the connecting rod 109 so that the drive part 303 and the drive engagement part 104 can cooperate.

[0156] Optionally, when the drive unit 303 and the 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 drive column 105 enters the drive groove 312. At this time, the first connecting rod 10 is simultaneously constrained by the first tooth 301 and the drive part 303. The constraint on the 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 drive engagement part 104 is constrained by the drive part 303, causing the first connecting rod 10 to run along the designed trajectory.

[0158] Optionally, there are multiple drive units 303, and the number of drive mating units 104 is equal to the number of drive units 303 and corresponds one-to-one; multiple drive units 303 sequentially engage with the corresponding drive mating units 104, and when the first drive unit 303 and the drive mating unit 104 switch from a non-engaging state to an engaging state, the first tooth 301 and the first rack 101 are in a meshing state.

[0159] The multiple drive units 303 are designated as the first drive unit 303, the second drive unit 303, and so on. When the first tooth 301 is still engaged with the first rack 101, the first drive unit 303 and the drive engagement part 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 drive unit 303 has engaged with the drive engagement part 104. At this time, the engagement of the first tooth 301 with the first rack 101 and the engagement of the drive unit 303 with the drive engagement part 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 drive unit 303 with the drive engagement part 104.

[0160] 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 drive part 303 and the drive engagement part 104 engage.

[0161] After the drive wheel 30 rotates to the set position, the drive unit 303 engages with the drive mating part 104 to drive the first connecting rod 10 to move, and the second tooth 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 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 drive unit 303 and the drive mating part 104, and the second connecting rod 20 is driven by the engagement of the second tooth 302 and the second rack 201. This combination of multiple driving methods facilitates the flexible movement of the air guide plate 70.

[0162] Optionally, such as Figure 6 As shown, the second rack 201 is a non-linear rack.

[0163] 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.

[0164] Optionally, the first rack 101 and the drive engagement part 104 are arranged sequentially along the length direction of the first connecting rod 10. When the drive part 303 and the 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.

[0165] When the first tooth 301 is not engaged with the first rack 101, the drive part 303 engages with the drive engagement part 104, thereby enabling the first connecting rod 10 to move through the engagement of the drive part 303 and the drive engagement part 104.

[0166] Optionally, such as Figure 7 and Figure 9 As shown, the first rack 101 is a non-linear rack.

[0167] 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.

[0168] After the air guide plate is opened to the second position, the first connecting rod is stationary, and the second rotating shaft rotates around the first rotating shaft so that the second rotating shaft moves along the arc-shaped fourth trajectory segment B4B5.

[0169] After the air guide plate is opened to the second position, the first link is stationary, and the second rotating shaft rotates around the first rotating shaft so that the second rotating shaft moves along the arc-shaped fourth trajectory segment B4B5. Compared with linear motion, arc-shaped motion can reduce the stroke of the second link, thereby reducing the space occupied by the drive device for the air guide plate.

[0170] The second tooth is a cylindrical gear, and the pitch line of the second rack and the part corresponding to the air guide plate after it is opened to the second position are the second type of arc shape B41B10.

[0171] After the air guide plate is opened to the second position, the drive unit and the drive engagement unit cooperate so that the rotation of the drive wheel can simultaneously drive the second link to move while keeping the first link stationary.

[0172] 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 drive portion 303 are both disposed on the first surface 304, and a second tooth 302 is disposed on the second surface 305.

[0173] The first tooth 301 and the 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 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 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.

[0174] The rotation axis of the drive wheel 30 is set perpendicular to the first surface 304 and the second surface 305.

[0175] The first link 10 is located inside the mechanism box 6 and moves relative to the mechanism box 6 between the retracted position of the retracted mechanism box 6 and the extended position of the extended mechanism box 6.

[0176] like Figure 8 As shown, one of the mechanism box 6 and the first connecting rod 10 is provided with a first positioning part, and the other of the mechanism box 6 and the first connecting rod 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 connecting rod 10 in the direction of the line connecting the first box cover 61 and the second box cover 62.

[0177] 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.

[0178] 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.

[0179] The positioning rib 111 is located in the positioning groove 617 and between the first groove wall and the second groove wall. The first groove wall restricts the positioning rib 111 to face the first groove wall, and the second groove wall restricts the positioning rib 111 to face the second groove wall. This limiting method has high reliability and low cost.

[0180] Optionally, one of the positioning grooves 617 in the mechanism box 6 and the first connecting rod 10 is also provided with a positioning protrusion 621, and a positioning wheel 622 is fitted onto the positioning protrusion 621, with the positioning groove 617 located on the positioning wheel 622.

[0181] When the mechanism box 6 has a positioning groove 617, the mechanism box 6 also has a positioning protrusion 621; when the first connecting rod 10 has a positioning groove 617, the first connecting rod 10 also has a positioning protrusion 621. A positioning wheel 622 is fitted onto the outside of the positioning protrusion 621. The positioning wheel 622 and the positioning protrusion 621 can be made of different materials. The positioning wheel 622 is made of a wear-resistant material to reduce wear. The positioning groove 617 is annular, extending circumferentially along the positioning wheel 622.

[0182] Optionally, the positioning rib 111 is made of a wear-resistant material to reduce wear on the positioning rib 111.

[0183] like Figure 8 As shown, the first box cover 61 is provided with a positioning protrusion 621, a positioning wheel 622 is sleeved on the outside of the positioning protrusion 621, and the first connecting rod 10 is provided with a positioning rib 111.

[0184] 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.

[0185] In this way, throughout the entire movement of the first link 10, at least one positioning groove 617 always engages with the positioning rib 111 to limit the movement of the first link 10 in the direction of the line connecting the first cover 61 and the second cover 62. Moreover, with multiple positioning grooves 617, only one positioning groove 617 needs to engage with the positioning rib 111 at different times to limit the movement of the first link 10 in the direction of the line connecting the first cover 61 and the second cover 62. It is not necessary for the positioning rib 111 to engage with every positioning groove 617 throughout the entire movement of the first link 10, so the length of the positioning rib 111 does not need to be too large, thereby reducing the size of the positioning rib 111.

[0186] There are two positioning slots 617. When the air guide plate 70 is in the closed position, the positioning rib 111 only cooperates with the positioning slot 617 that is far away from the air guide plate 70. As the air guide plate 70 moves, the positioning rib 111 cooperates with both positioning slots 617. Then, as the air guide plate 70 moves, the positioning rib 111 only cooperates with the positioning slot 617 that is close to the air guide plate 70.

[0187] Alternatively, the first positioning part can be a positioning rib 111, and both the first positioning mating part and the second positioning mating part can be in the form of a groove, with the positioning rib 111 inserted into the groove and sliding relative to the groove.

[0188] Optionally, the driving device for the air conditioning deflector also includes a second link 20, which is disposed inside the mechanism box 6, and the first link 10 and the second link 20 are arranged sequentially along the direction from the first box cover 61 to the second box cover 62; when the first positioning part is disposed in the mechanism box 6, the first positioning part is disposed in the first box cover 61 and there is a gap between the first positioning part and the second box cover 62, so as to avoid the arrangement of the first positioning part affecting the movement of the second link 20; when the first positioning mating part and the second positioning mating part are disposed in the mechanism box 6, both the first positioning mating part and the second positioning mating part are disposed in the first box cover 61 and there are gaps between the first positioning mating part, the second positioning mating part and the second box cover 62, so as to avoid the arrangement of the first positioning mating part and the second positioning mating part affecting the movement of the second link 20.

[0189] The drive unit for the air conditioning deflector also includes a power source, which includes drive wheels 30.

[0190] like Figure 8 As shown, the mechanism box 6 is provided with a stroke restriction area 623; the first link 10 includes a drive engagement structure 115 that cooperates with the drive unit 303 so that the power source drives the first link 10 to move, and the drive engagement structure 115 is at least partially located within the stroke restriction area 623; wherein, during the movement of the first link 10, the drive engagement structure 115 is at least partially located within the stroke restriction area 623 and moves relative to the stroke restriction area 623 so that the stroke restriction area 623 limits the movement area of ​​the drive engagement structure 115, so that the first link 10 moves between the first limit position and the second limit position, which can effectively prevent the first link 10 from excessively deviating during the movement, thereby accurately limiting the movement range and position of the air guide plate 70.

[0191] Optionally, the first link 10 is located between the power source and the first cover 61, and the travel limiting region 623 is located on the first cover 61. On the one hand, the distance between the first link 10 and the travel limiting region 623 is small, which facilitates the cooperation between the first link 10 and the travel limiting region 623; on the other hand, the cooperation between the drive cooperation structure 115 and the travel limiting region 623 will not affect the cooperation between the drive unit 303 and the power cooperation structure, that is, it will not affect the drive of the power source to the first link 10.

[0192] Optionally, the mechanism box 6, such as the first box cover 61, is recessed on the surface facing the first connecting rod 10 to form a stroke restriction area 623. On the one hand, the recessed form ensures that the setting of the restriction area does not affect the setting of the drive engagement structure 115. On the other hand, it can also enhance the strength of the first box cover 61.

[0193] 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 drive engagement part 104 and a connecting rod 109. The connecting rod 109 connects the first link body 114 and the drive engagement part 104.

[0194] During the movement of the first link 10, the connecting rod 109 is located within the travel restriction area 623 and moves relative to the travel restriction area 623, so that the travel restriction area 623 limits the movement area of ​​the drive engagement structure 115.

[0195] The limiting effect of the travel restriction area 623 on the drive engagement structure 115 is achieved by limiting the connecting rod 109 through the travel restriction area 623, rather than by limiting the drive engagement part 104 through the travel restriction area 623. This ensures that the limiting effect of the travel restriction area 623 does not affect the engagement between the drive engagement part 104 and the drive part 303, and thus does not affect the drive of the power source on the first connecting rod 10.

[0196] Optionally, the first box cover 61, the connecting rod 109, and the first rod body 114 are arranged sequentially.

[0197] On the one hand, the connecting rod 109 is closer to the first cover 61, and thus closer to the travel restriction area 623, which facilitates the engagement of the connecting rod 109 with the travel restriction area 623. On the other hand, the 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 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 drive engagement part 104 and the first rack 101.

[0198] The first surface 304 is provided with a driving part 303 for driving the first connecting rod 10, and the second surface 305 is provided with a second tooth part 302 for driving the second connecting rod 20. The driving part 303 includes a driving groove 312 or a driving column 105.

[0199] The drive unit 303 engages with the first connecting rod 10, and the second toothed part 302 engages with the second connecting rod 20. The 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 drive unit 303 includes a drive groove 312 or a drive column 105, which is different from the toothed part 302. By using 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. This 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.

[0200] Optionally, the second tooth 302 extends circumferentially along the drive wheel 30 and is either annular or non-annular.

[0201] 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.

[0202] Optionally, when the drive unit 303 is a drive post 105, the drive post 105 protrudes from the first toothed part 301 to facilitate the engagement of the drive post 105 with the drive groove 312.

[0203] 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.

[0204] Optionally, the drive wheel 30 is provided with a partition plate. During at least a part of the opening of the air guide plate 70, the partition plate 311 is provided between the first link 10 and the second link 20 to separate the first link 10 and the second link 20, which can prevent the first link 10 from hitting the drive wheel and also prevent the second link 20 from hitting the drive wheel.

[0205] 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.

[0206] 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.

[0207] 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.
