[0016] In this disclosure, the terms "upper," "lower," "inner," "middle," "outer," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for better description of the embodiments of this disclosure and their implementations, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to require them to be constructed and operated in a specific orientation.

For example, "connection" can refer to an installation connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can refer to the internal communication between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0018] 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.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0020] This disclosure provides a driving mechanism for an air guide plate, which can also be referred to as a driving structure.

[0021] The drive mechanism includes an extension link 1. The extension link 1 moves under the drive of the drive element 3. The extension link 1 includes a first connecting end 11 connected to the connecting member of the air guide plate. The first connecting end 11 is pivotally connected to the connecting member.

[0022] The drive mechanism also includes a rotating link 2. The rotating link 2 moves under the drive of the drive element 3. The rotating link 2 includes a second connecting end 21 that is connected to the connecting member of the air guide plate. The second connecting end 21 is drivenly connected to the connecting member.

[0023] Specifically, the driving element 3 drives the extended connecting rod 1 to move along the first track 51 and drives the rotating connecting rod 2 to move along the second track 61, so as to drive the air guide plate to open in the first direction; the driving element 3 drives the extended connecting rod 1 to move along the third track 52 and drives the rotating connecting rod 2 to move along the fourth track 62, so as to drive the air guide plate to open in the second direction.

[0024] In the driving mechanism provided in this embodiment, the rotating link 2 is driven to connect with the connecting member of the air guide plate to drive the air guide plate to rotate, thereby improving the smoothness of the air guide plate rotation process and avoiding the problem of the air guide plate getting stuck; the extending link 1 is pivotally connected with the connecting member of the air guide plate to drive the air guide plate to extend.

[0025] In this way, there is no fixed distance between the two shafts of the two connecting rods mentioned above. Even if the actual production drive mechanism deviates from the design scheme, the air guide plate will not get stuck during rotation, and the first connecting end 11 of the extended connecting rod 1 will not be worn.

[0026] As can be seen, the driving mechanism provided in this embodiment improves the stability of the air guide plate driving process. Furthermore, the driving mechanism provided in this embodiment eliminates the fixed distance between the two rotating shafts, thus allowing the rotating link 2 and the extending link 1 to achieve the rotation of the air guide plate without extending a large distance, reducing the size of the driving mechanism and the space it occupies in the air conditioner indoor unit.

[0027] The second connecting end 21 of the rotating link 2 is driven to be connected to the connecting member. This can be understood as the second connecting end 21 of the rotating link 2 and the connecting member not being driven by an active power source such as a motor, but being driven through meshing between teeth.

[0028] The connector provides a connection point for the rotation link 2 and the extension link 1 to connect with the air guide plate. Optionally, the connector can be part of the air guide plate body 7 or a separate component disposed on the air guide plate body 7. Optionally, the connector is integrally formed with the air guide plate body 7; or, the connector is snapped into the air guide plate body 7, etc. Optionally, the connector is perpendicular to the air guide plate body 7.

[0029] When the driving element 3 drives the extension link 1 to move along the first track 51, and simultaneously drives the rotating link 2 to move along the second track 61, the air guide plate opens in the first direction.

[0030] When the driving element 3 drives the extension link 1 to move along the third track 52, and simultaneously drives the rotating link 2 to move along the fourth track 62, the air guide plate opens in the second direction.

[0031] The extension link 1 can move along the first track 51 and the third track 52 under the drive of the drive element 3. The first track 51 and the third track 52 are connected, and the extension directions of the first track 51 and the third track 52 are different, that is, the first track 51 and the third track 52 are bent and connected. Optionally, under the drive of the drive element 3, the extension link 1 first moves along the first track 51, and then moves along the third track 52.

[0032] The rotating link 2 can move along the second track 61 and the fourth track 62 under the drive of the driving element 3. The second track 61 and the fourth track 62 are connected, and the extension directions of the second track 61 and the fourth track 62 are different, that is, the second track 61 and the fourth track 62 are bent and connected. Optionally, the rotating link 2, driven by the driving element 3, first moves along the second track 61 and then moves along the fourth track 62.

[0033] When guiding airflow, the air guide vane of an air conditioner indoor unit typically needs to rotate to different guiding angles to achieve different airflow modes, such as upward blowing of cold air, maximum cooling airflow, wraparound airflow, and downward blowing of heating airflow. In the driving mechanism provided in this embodiment, the first track 51 and the third track 52 are bent and connected, and the second track 61 and the fourth track 62 are bent and connected. This improves the driving accuracy of the driving mechanism in determining the guiding angle of the air guide vane, allowing the air guide vane to rotate more precisely to the required guiding angle.

[0034] Optionally, the connecting member of the air guide plate includes a rotating gear 4, wherein the first connecting end 11 of the extended connecting rod 1 includes a first pivot shaft, which is pivotally connected to the gear center 41 of the rotating gear 4; the second connecting end 21 of the rotating connecting rod 2 includes a first rack segment, which meshes with the rotating gear 4 to drive the rotating connecting rod 2 to the rotating gear 4.

[0035] Optionally, the first pivot axis of the extending connecting rod 1 is cylindrical, and the center 41 of the rotating gear 4 is cylindrical. The cylindrical first pivot axis is located at the center 41 of the cylindrical gear, realizing the pivotal connection between the extending connecting rod 1 and the rotating gear 4. The pivotal connection can be understood as the rotating gear 4 extending along with the extending connecting rod 1, but when the rotating gear 4 rotates, the extending connecting rod 1 does not rotate accordingly.

[0036] The air guide plate body 7 is fixedly connected to the connecting piece, so that the rotation of the rotating gear 4 of the connecting piece can be reflected in the rotation of the air guide plate body 7. When the movement speed of the first rack segment of the rotating connecting rod 2 is different from the movement speed of the rotating gear 4, the first rack segment meshes with the rotating gear 4, the rotating gear 4 rotates, and thus drives the air guide plate to rotate.

[0037] Optionally, the first rack segment is a strip-shaped toothed portion. Optionally, the first rack segment is arc-shaped.

[0038] Optionally, the drive element 3 includes a crank, which includes a first crankshaft 31 and a second crankshaft 32. The first crankshaft 31 is driven to the extended connecting rod 1 so that the crank drives the extended connecting rod 1 to move. The second crankshaft 32 is driven to the rotating connecting rod 2 so that the crank drives the rotating connecting rod 2 to move.

[0039] The crank rotates under the drive of the drive motor. When the crank rotates, the first crankshaft 31 of the crank drives the extension connecting rod 1 to extend, and at the same time, the second crankshaft 32 of the crank drives the rotating connecting rod 2 to extend.

[0040] Optionally, the first crankshaft 31 is cylindrical, and similarly, the second crankshaft 32 is cylindrical.

[0041] Optionally, the rotating gear 4 is provided with a missing tooth portion 42.

[0042] The rotating gear 4 is not fully toothed, but has a missing tooth section 42, meaning it has a non-meshing section. This allows the air guide plate to rotate in different directions by only using a portion of the teeth of the rotating gear 4 to mesh with the first rack section, reducing the overall size of the drive mechanism. Furthermore, the teeth at both ends of the rotating gear 4 can be used for rotational limiting.

[0043] Optionally, the crank is fan-shaped.

[0044] Optionally, the first track 51 is connected to the third track 52, and the first track 51 is arc-shaped. Optionally, the first track 51 is circular arc-shaped.

[0045] Optionally, there are two or more first tracks 51 and third tracks 52. Optionally, the multiple first tracks 51 are staggered in the horizontal direction, that is, the multiple first tracks 51 are not set on the same horizontal line. This improves the motion stability of the extended connecting rod 1 moving along the track.

[0046] Optionally, the second track 61 is connected to the fourth track 62, and the second track 61 is arc-shaped. Optionally, the second track 61 is circular arc-shaped.

[0047] Optionally, there are two or more second tracks 61 and fourth tracks 62. Optionally, the multiple second tracks 61 are staggered in the horizontal direction, that is, the multiple second tracks 61 are not set on the same horizontal line. This improves the motion stability of the extended connecting rod 1 moving along the track.

[0048] Optionally, when the extension link 1 moves along the first track 51, it has an extension link motion center; when the rotating link 2 moves along the second track 61, it has a rotating link motion center, wherein the extension link motion center and the rotating link motion center overlap.

[0049] The first track 51 is arc-shaped, and when the extending connecting rod 1 moves along the first track 51, it has a center of motion for the extending rod. The second track 61 is also arc-shaped, and when the rotating connecting rod 2 moves along the second track 61, it has a center of motion for the rotating rod. Furthermore, the center of motion for the extending rod and the center of motion for the rotating rod overlap and are both... Figure 37 Point B in the diagram.

[0050] When the driving element 3 drives the extension link 1 to move along the first track 51 and drives the rotating link 2 to move along the second track 61, the air guide plate opens in the first direction, and the rotation center of the air guide plate forms the first guide plate motion trajectory, wherein the first guide plate motion trajectory is arc-shaped.

[0051] Optionally, the first guide plate's motion trajectory has a guide plate motion center B, wherein the guide plate motion center B overlaps with the extension rod motion center; and / or, the guide plate motion center B overlaps with the rotating rod motion center. Figure 37 As shown.

[0052] Optionally, the first track 51 has a first length and the third track 52 has a third length, wherein the first length is greater than the third length.

[0053] The first track 51 is connected to the third track 52. Optionally, the first length of the first track 51 can be understood as the length of the trajectory of the first sliding shaft 14 of the extended link 1 along the first track 51, that is, the extension length of the first track 51 itself; similarly, the third length of the third track 52 can be understood as the length of the trajectory of the first sliding shaft 14 of the extended link 1 along the third track 52, that is, the extension length of the third track 52 itself.

[0054] Optionally, the second track 61 has a second length and the fourth track 62 has a fourth length, wherein the second length is greater than the fourth length.

[0055] The second track 61 is connected to the fourth track 62. Optionally, the second length of the second track 61 can be understood as the length of the trajectory of the second sliding shaft 23 of the rotating link 2 along the second track 61, that is, the extension length of the second track 61 itself; similarly, the fourth length of the fourth track 62 can be understood as the length of the trajectory of the second sliding shaft 23 of the rotating link 2 along the fourth track 62, that is, the extension length of the fourth track 62 itself.

[0056] Optionally, when the air guide plate opens from the closed position to the first air guide position along the first direction, ∠A2M2A11 is related to ∠A2BA1, ∠C1BC2, and ∠D1BD2. Wherein, ∠A2M2A11 is the rotation angle of the air guide plate from the closed position to the first air guide position; ∠A2BA1 is the angle formed by the rotation center of the air guide plate moving from point A1 to point A2 from the closed position to the first air guide position; ∠C1BC2 is the angle formed by the extension link 1 moving from point C1 to point C2 from the closed position to the first air guide position; ∠D1BD2 is the angle formed by the rotation link 2 moving from point D1 to point D2 from the closed position to the first air guide position; and B is the center of the air guide plate's rotation circle. That is, the rotation centers A1, A2, and A3 of the air guide plate move around the center of the rotation circle B.

[0057] The first direction is the direction in which the air guide plate opens upwards. Both the first and second air guide positions are air guide positions when the air guide plate is opened upwards. The first air guide position is where the cooling air rises. Figure 32 As shown, and corresponding Figure 36 Position 2 in the middle; the second air guide position is the maximum air supply for cooling, such as... Figure 33 As shown, and corresponding Figure 36 Position 3 in the middle. Close the corresponding position. Figure 36 Position 1 in the middle.

[0058] Figure 36 In the diagram, A1, A2, A3, and A4 are the rotation centers of the guide plate driven by the rotating link 2, and A1, A2, A3, and A4 correspond to positions 1, 2, 3, and 4 of the guide plate, respectively; C1, C2, C3, and C4 are points in the first motion trajectory of the extended link 1 that correspond to positions 1, 2, 3, and 4 of the guide plate, respectively; D1, D2, D3, and D4 are points in the second motion trajectory of the rotating link 2 that correspond to positions 1, 2, 3, and 4 of the guide plate, respectively.

[0059] Figure 37 Point B in the diagram is the center of the guide plate's rotation circle, driven by the extended connecting rod 1. During the guide plate's movement from the closed position to the first guide position and then to the second guide position, the center B of the guide plate's rotation circle remains fixed.

[0060] Connect points A1M1 to form a line. At point M2, draw a line A11M2 parallel to A1M1, thus obtaining ∠A2M2A11. Connect points A2, B, and A1 in sequence to obtain angle ∠A2BA1; similarly, connect points C1, B, and C2 in sequence to obtain ∠C1BC2; and connect points D1, B, and D2 in sequence to obtain ∠D1BD2.

[0061] Optionally, the indoor unit of the air conditioner also includes a housing with an air outlet. The housing has an air outlet, and the air guide plate includes an upper edge near the upper edge of the air outlet and a lower edge near the lower edge of the air outlet. When the air guide plate is in the closed position, the lower edge of the air guide plate is at position M1; when the air guide plate is opened to the first air guiding position, the lower edge of the air guide plate is at position M2. Figure 36 As shown.

[0062] Optionally, when the air guide plate is opened from the closed position to the first air guide position along the first direction, the rotation angle ∠A2M2A11 of the air guide plate satisfies the following relationship: ∠A2M2A11=∠A2BA1+(∠C1BC2-∠D1BD2)×k.

[0063] By linking the rotation angle of the air guide plate with the rotation angles of the extending link 1 and the rotating link 2, the accuracy of the drive mechanism's control over the air guide plate's rotation angle is improved. Furthermore, the rotation angles of the extending link 1 and the rotating link 2 can be calculated in reverse based on the air guide plate's rotation angle, simplifying the design process of the drive mechanism and reducing design errors.

[0064] The precise correlation of the motion angles of each component enables the quantitative design and precise control of the air guide plate opening angle. Through this formula, the motion angles of each link and rotation center can be calculated in reverse according to the design requirements of the target air guide angle, simplifying the product design process, reducing design errors, and ensuring the consistency of the air guide angle of each product during mass production.

[0065] Optionally, k = BE / r, where E is any position of the pitch circle of the first rack segment of the rotating connecting rod 2, BE is the pitch circle radius of the first rack segment of the rotating connecting rod 2, and r is the pitch circle radius of the rotating gear 4.

[0066] In this embodiment of the disclosure, during the process of the air guide plate moving from position 1 to position 3, the air guide plate moves to any point and satisfies the formula relationship.

[0067] Optionally, when the air guide plate opens in the second direction, the connecting rod extends to perform a translational movement.

[0068] like Figure 36As shown, the extending connecting rod moves from point C3 to point C4, the rotating connecting rod moves from point D3 to point D4, the air guide plate opens in the second direction, and the rotation center of the air guide plate moves from point A3 to point A4. The extending connecting rod translates along the curve from A3 to A4 at a speed of V3. Taking point A3 as an example, establish as follows... Figure 36 In the coordinate system shown, the position vector of point A3 is R3(t), and its velocity is V3 = dR3 / dt. It can be understood that the curves A3A4 and C3C4 have the same shape and dimensions, only their positions differ.

[0069] Optionally, when the air guide plate opens in the second direction, the motion of the rotating link includes rotational motion, wherein the rotational angular velocity W2 of the rotating link is related to the pitch circle radius BE of the first rack segment of the rotating link and the pitch circle radius r of the rotating gear.

[0070] Optionally, when the air guide plate opens in the second direction, the rotational angular velocity W2 of the rotating link satisfies the following relationship: W2 = -r / BE×W1, where W1 is the rotational angular velocity of the air guide plate's center of rotation.

[0071] Optionally, W1 can be set according to the required rotation angle of the air guide plate and the movement time from A3 to A4. In this embodiment of the present disclosure, the rotation direction of the rotating link is opposite to the rotation direction of the air guide plate.

[0072] Optionally, when the guide vane opens in the second direction, the motion of the rotating link also includes translational motion. During this process, the rotating link undergoes a combined translational and rotational motion. Thus, in addition to maintaining the same velocity V3 as the extending link, the rotating link also has a rotational angular velocity W2 around the center of motion B of the guide vane. Optionally, when the guide vane moves from point A3 to point A4, the center of motion B of the guide vane moves.

[0073] Optionally, when the air guide plate opens in the second direction, the speed of the extended connecting rod in translational motion is the same as the speed of the translational motion of the rotating connecting rod.

[0074] Optionally, the drive element 3 has a drive center 35, and the extension link 1 and the rotating link 2 are both located on the same side of the drive center 35.

[0075] The drive center 35 of drive element 3 can be understood as the position where drive element 3 is directly connected to the motor shaft. For example... Figures 8 to 10 As shown. A line passing through the drive center 35 of the drive element 3 is drawn along the extension direction of the drive mechanism, and the extended connecting rod 1 and the rotating connecting rod 2 are both located on the same side of this line. Figure 3 The arrows in the diagram indicate the direction of the extension of the drive mechanism.

[0076] Optionally, the driving element 3 drives the extended connecting rod 1 to move along the first motion trajectory, and the driving element 3 drives the rotating connecting rod 2 to move along the second motion trajectory, wherein the first motion trajectory and the second motion trajectory are both located on the same side of the driving center 35.

[0077] As can be seen, in this embodiment, the entire movement of the extension link 1 and the rotating link 2 is located on the same side of the drive center 35 of the drive element 3, so that the extension and retraction processes of the extension link 1 and the rotating link 2 do not pass through the drive center 35 of the drive element 3. In this way, the drive element 3 can be limited by the first drive box 5 and the second drive box 6, which simplifies the structure and reduces the number of parts in the drive mechanism.

[0078] Optionally, the drive mechanism may also include a first drive box 5 and a second drive box 6.

[0079] The first drive box 5 is provided with a first track 51 and a third track 52. The extended connecting rod 1 moves along the first track 51 and the third track 52 to form a first motion trajectory. The second drive box 6 is provided with a second track 61 and a fourth track 62. The rotating connecting rod 2 moves along the second track 61 and the fourth track 62 to form a second motion trajectory. The drive element 3 drives the extended connecting rod 1 to move along the first track 51 and drives the rotating connecting rod 2 to move along the second track 61, thereby opening the air guide plate in a first direction; the drive element 3 also drives the extended connecting rod 1 to move along the third track 52 and drives the rotating connecting rod 2 to move along the fourth track 62, thereby opening the air guide plate in a second direction. Furthermore, the first track 51, the second track 61, the third track 52, and the fourth track 62 are all located on the same side of the drive center 35.

[0080] The first track 51 and the third track 52 of the first drive box 5 are both located on the same side of the drive center 35 of the drive element 3. The second track 61 and the fourth track 62 of the second drive box 6 are also located on the same side of the drive center 35 of the drive element 3, as shown below. Figure 3 As shown. In this way, the extending link 1 and the rotating link 2 drive the air guide plate to open in the first direction and the second direction, and the entire extension process of the two links is located on the same side of the drive center 35 of the drive element 3.

[0081] Optionally, the driving element 3 includes a first driving connection end 36 and a second driving connection end 37, wherein the first driving connection end 36 is connected to the first driving box 5, and the second driving connection end 37 is connected to the second driving box 6.

[0082] The first drive connection end 36 and the second drive connection end 37 are used to limit the movement of the drive element 3. The first drive connection end 36 is connected to the first drive box 5 for limiting, and the second drive connection end 37 is connected to the second drive box 6 for limiting. In this way, the two sides of the drive element 3 are respectively limited and connected to the first drive box 5 and the second drive box 6. That is, without the need for other limiting structures or through connecting rods, the two sides of the drive element 3 can be respectively set in the two drive boxes, simplifying the complexity of the drive mechanism.

[0083] Optionally, the first drive connection end 36 and the second drive connection end 37 are coaxially arranged with the drive center 35.

[0084] The first drive connection end 36 is located on one side of the drive center 35, and the second drive connection end 37 is located on the other side of the drive center 35. The two drive connection ends are coaxially arranged with the drive center 35. This improves the limiting stability of the two drive connection ends and the drive element 3, and improves the driving accuracy of the drive element 3 on the extension link 1 and the rotating link 2.

[0085] Optionally, the first drive box 5 is provided with a drive connection hole, and the first drive connection end 36 is disposed through the drive connection hole, and the motor output shaft of the drive motor is drivenly connected to the first drive connection end 36; the second drive box 6 is provided with a drive connection post, and the second drive connection end 37 is sleeved on the outside of the drive connection post; or, the first drive box 5 is provided with a drive connection post 53, and the first drive connection end 36 is sleeved on the outside of the drive connection post 53; the second drive box 6 is provided with a drive connection hole 63, and the second drive connection end 37 is disposed through the drive connection hole 63, and the motor output shaft of the drive motor is drivenly connected to the second drive connection end 37.

[0086] When the first drive box 5 is provided with a drive connection hole, the first drive connection end 36 of the drive element 3 passes through the drive connection hole. In this way, the motor output shaft of the drive motor can be driven to connect with the first drive connection end 36 of the drive element 3. At this time, the drive motor is located on the outside of the first drive box 5.

[0087] When the second drive box 6 is provided with a drive connection hole 63, the second drive connection end 37 of the drive element 3 passes through the drive connection hole 63. In this way, the motor output shaft of the drive motor can be driven to connect with the second drive connection end 37 of the drive element 3. At this time, the drive motor is located on the outside of the second drive box 6.

[0088] Optionally, the drive element 3 has a drive center 35, and the drive element 3 is provided with a first crankshaft 31 and a third crankshaft 33 for driving the extension connecting rod 1. The drive center 35 forms a first drive line with the first crankshaft 31, and the drive center 35 forms a third drive line with the third crankshaft 33. The angle α1 formed by the first drive line and the third drive line is 90°≤α1<180°. Figure 9 As shown.

[0089] The first crankshaft 31 and the third crankshaft 33 of the drive element 3 rotate around the drive center 35, and the first crankshaft 31 and the third crankshaft 33 drive the extension link 1 to move, respectively or in sequence, thereby indirectly providing driving force for the extension or retraction of the extension link 1.

[0090] like Figure 9 As shown, the included angle between the first drive connection line and the third drive connection line is a1, and 90°≤a1<180°. Optionally, a1 can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, or 175°, etc. Optionally, 135°≤a1<180°. For example, a1 can be 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, or 175°, etc. In this way, the problem of motion interference between the first crankshaft 31 and the third crankshaft 33 caused by an excessively small included angle a1 is avoided, ensuring that the power of the drive element 3 can be smoothly and efficiently transmitted to the extended connecting rod 1, driving the air guide plate body 7 to move smoothly.

[0091] Optionally, the drive element 3 is further provided with a second crankshaft 32 and a fourth crankshaft 34 for driving the rotating connecting rod 2 to move. The drive center 35 forms a second drive connection line with the second crankshaft 32, and the drive center 35 forms a fourth drive connection line with the fourth crankshaft 34. The included angle α2 formed by the second drive connection line and the fourth drive connection line is 90°≤α2<180°.

[0092] The second crankshaft 32 and the fourth crankshaft 34 of the drive element 3 rotate around the drive center 35, and the second crankshaft 32 and the fourth crankshaft 34 drive the rotating connecting rod 2 to move, respectively or in sequence, thereby indirectly providing driving force for the extension or retraction of the rotating connecting rod 2.

[0093] In this way, the extended connecting rod 1 and the rotating connecting rod 2 together drive the air guide plate body 7 to achieve air guidance, opening or closing at different angles.

[0094] like Figure 9As shown, the included angle between the second drive connection line and the fourth drive connection line is a2, and 90°≤a2<180°. Optionally, a2 can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, or 175°, etc. Optionally, 135°≤a2<180°. For example, a2 can be 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, or 175°, etc. In this way, the problem of motion interference between the second crankshaft 32 and the fourth crankshaft 34 caused by an excessively small included angle a2 is avoided, ensuring that the power of the drive element 3 can be smoothly and efficiently transmitted to the rotating connecting rod 2, driving the air guide plate body 7 to move smoothly.

[0095] Optionally, the distance between the first crankshaft 31 and the drive center 35 is the first shaft radius r1, the distance between the second crankshaft 32 and the drive center 35 is the second shaft radius r2, and r1 > r2.

[0096] so, Figure 36 The middle air guide plate moves from position 1 to position 3, causing the rotation speed of the rotating link 2 to be less than the movement speed of the extended link 1, so that the air guide plate body 7 rotates counterclockwise as shown in the figure, that is, the air guide plate body 7 opens upward, that is, opens in the first direction.

[0097] The distance between the third crankshaft 33 and the drive center 35 is the radius r3 of the third crankshaft, and the distance between the fourth crankshaft 34 and the drive center 35 is the radius r4 of the fourth crankshaft, and r3 < r4.

[0098] so, Figure 36 The middle air guide plate moves from position 3 to position 4, causing the rotation speed of the rotating link 2 to be greater than the movement speed of the extended link 1, so that the air guide plate body 7 rotates clockwise as shown in the figure, that is, the air guide plate body 7 opens downward, that is, opens in the second direction.

[0099] Optionally, the drive element 3 includes a crank, wherein the crank is fan-shaped. For example... Figure 10 As shown.

[0100] Optionally, the crank includes a first crank face 301 and a second crank face 302, wherein a first crankshaft 31 and a third crankshaft 33 are disposed on the first crank face 301, and a second crankshaft 32 and a fourth crankshaft 34 are disposed on the second crank face 302.

[0101] The first crankshaft 31 and the third crankshaft 33 are disposed on the first crank face 301 of the crank, and the second crankshaft 32 and the fourth crankshaft 34 are disposed on the fourth crank face of the crank. In this way, the four crankshafts disposed on the two crank faces can all extend in a fan shape with the drive center 35 as the reference, so that the four crankshafts do not interfere with each other during the movement, thereby improving the driving stability and accuracy of the crank driving the extended connecting rod 1 and the rotating connecting rod 2 simultaneously.

[0102] Optionally, the first crankshaft 31 and the third crankshaft 33 have the same protrusion height from the first crank face 301; similarly, the second crankshaft 32 and the fourth crankshaft 34 have the same protrusion height from the second crank face 302.

[0103] Optionally, the first crank face 301 includes a first crank end 3011 extending from the drive center 35 to the first end, and a third crank end 3012 extending from the drive center 35 to the second end, wherein the first crankshaft 31 is disposed at the first crank end 3011, and the third crankshaft 33 is disposed at the third crank end 3012; the second crank face 302 includes a second crank end 3021 extending from the drive center 35 to the first end, and a fourth crank end 3022 extending from the drive center 35 to the second end, wherein the second crankshaft 32 is disposed at the second crank end 3021, and the fourth crankshaft 34 is disposed at the fourth crank end 3022.

[0104] The first crankshaft 31 is disposed at the end of the first crank end 3011, or near the end of the first crank end 3011; similarly, the second crankshaft 32 is disposed at the end of the second crank end 3021, or near the end of the second crank end 3021; ​​similarly, the third crankshaft 33 is disposed at the end of the third crank end 3012, or near the end of the third crank end 3012; similarly, the fourth crankshaft 34 is disposed at the end of the fourth crank end 3022, or near the end of the fourth crank end 3022.

[0105] Optionally, the connecting member of the air guide plate includes a rotating gear 4, the second connecting end 21 of the rotating link 2 includes a first rack segment, the first rack segment meshes with the rotating gear 4 so that the rotating link 2 is driven to connect with the rotating gear 4, and the rotating gear 4 is provided with a toothed portion 42.

[0106] The drive mechanism provided in this embodiment has a toothed portion 42 on the rotating gear 4. The toothed portion 42 is the area on the rotating circumference of the rotating gear 4 where no teeth are provided. The toothed portion 42 of the rotating gear 4 limits the rotation angle of the rotating gear 4, thereby limiting the opening angle of the air guide plate body 7 in the first direction and the second direction. This avoids structural damage caused by excessive rotation of the air guide plate body 7, and also prevents the air guide plate body 7 from affecting the air conditioning output effect due to excessive rotation angle, thus improving the safety and service life of the drive mechanism.

[0107] Optionally, the rotating circumferential surface of the rotating gear 4 includes a toothed portion 42 and a toothed portion 43, the arc length of the toothed portion 42 is L1, and the arc length of the toothed portion 43 is L2, wherein L1≥L2.

[0108] like Figure 11 As shown, the circumference of the rotating surface is L, the arc length of the toothed portion 42 is L1, and the arc length L2 of the toothed portion 43 is L-L1. In this embodiment, L1≥L2, that is, the arc length of the toothed portion 42 is greater than or equal to the arc length of the toothed portion 43. In this way, the rotation of the air guide plate body 7 is achieved with only a few teeth on the rotating surface of the rotating gear 4, which reduces the meshing contact area between the first rack segment and the rotating gear 4, reduces wear during meshing, and extends the service life of the drive mechanism.

[0109] Optionally, the rotating gear 4 includes a first gear mounting end 44 disposed at one end of the rotating circumferential surface and a second gear mounting end 45 disposed at the other end of the rotating circumferential surface, wherein the first gear mounting end 44 is pivotally connected to the first connecting end 11 of the extended connecting rod 1, and the second gear mounting end 45 is used to connect to the air guide plate.

[0110] The first gear mounting end 44 and the second gear mounting end 45 of the rotating gear 4 are used for fixed installation of the rotating gear 4. The first gear mounting end 44 is pivotally connected to the extending connecting rod 1. For example, the first gear mounting end 44 is provided with a pivot hole for pivotal connection, and the extending connecting rod 1 is provided with a pin that can extend into the pivot hole. The second gear mounting end 45 is used to connect to the air guide plate. Thus, when the rotating gear 4 rotates, the air guide plate rotates synchronously through the second gear mounting end 45, thereby adjusting the air guide angle.

[0111] Optionally, when the air guide plate is in the closed state, the toothed portion 43 of the rotating gear 4 includes a meshing toothed portion 431 that meshes with the first rack segment, a first non-meshing toothed portion 432 disposed at one end of the meshing toothed portion 431, and a second non-meshing toothed portion 433 disposed at the other end of the meshing toothed portion 431, wherein the number of teeth of the first non-meshing toothed portion 432 and the second non-meshing toothed portion 433 are different.

[0112] For example, the number of teeth in the first non-meshing tooth segment 432 can be 2, 3, or 4, and the number of teeth in the second non-meshing tooth segment 433 can be 3, 4, or 5. Optionally, the number of teeth in the meshing tooth segment 431 can be 2, 3, or 4. Figure 12 As shown, the first non-meshing tooth segment 432 has 2 teeth, the second non-meshing tooth segment 433 can have 3 teeth, and the meshing tooth segment 431 can have 2 teeth.

[0113] Optionally, the first non-meshing tooth segment 432 is located near the end of the second connecting end 21 of the rotating connecting rod 2, wherein the number of teeth of the first non-meshing tooth segment 432 is n1, the number of teeth of the second non-meshing tooth segment 433 is n2, and n1 < n2.

[0114] When the air guide plate body 7 is closed, the first non-meshing tooth segment 432 of the toothed portion 43 of the rotating gear 4 is the portion near the end of the second connecting end 21. In this embodiment, n1 < n2.

[0115] Optionally, the number of teeth in the meshing tooth segment 431 is n3, where n1 < n3.

[0116] When the air guide plate body 7 is closed, the number of teeth in the meshing tooth section 431 is n3, such as Figure 12 As shown, the number of teeth n3 in the meshing tooth segment 431 is 2.

[0117] Optionally, the connecting member of the air guide plate includes a rotating gear 4, and the second connecting end 21 of the rotating link 2 includes a first rack segment. The first rack segment meshes with the rotating gear 4 so that the rotating link 2 is driven to connect with the rotating gear 4. Furthermore, the rotating gear 4 and / or the first rack segment are provided with an identification structure indicating that the rotating gear 4 and the first rack segment are engaged.

[0118] During the initial assembly of the drive mechanism, the teeth of the rotating gear 4 must correspond one-to-one with the teeth of the first rack segment. This ensures precise control of the rotation angle of the air guide plate body 7 when the drive mechanism drives the air guide plate. In this embodiment, the rotating gear 4 and the first rack segment are provided with marking structures indicating their engagement. Referring to these marking structures, the teeth of the rotating gear 4 and the teeth of the first rack segment can be quickly and accurately aligned and installed. This ensures proper meshing and avoids transmission jamming and component wear caused by misaligned assembly.

[0119] Optionally, the marking structure can be disposed on the rotating gear 4, on the first rack segment, or on both the rotating gear 4 and the first rack segment. Optionally, the marking structure can be integrally formed with the rotating gear 4 and / or the first rack segment.

[0120] Optionally, the marking structure of the rotating gear 4 is disposed on the side of the teeth of the rotating gear 4; and / or, the marking structure of the first rack segment is disposed on the side of the teeth of the first rack segment.

[0121] The marking structure is disposed on the side of the rotating gear 4 and / or the first rack segment. Optionally, the rotating gear 4 includes a first gear mounting end 44 connected to the extending connecting rod 1 and a second gear mounting end 45 opposite to the first gear mounting end 44. Optionally, the marking structure is disposed on the side of the toothed portion 43 of the rotating gear 4 facing the second gear mounting end 45. Optionally, the marking structure of the first rack segment is disposed on the same side as the marking structure of the rotating gear 4, such as... Figure 13 As shown.

[0122] Optionally, the teeth of the rotating gear 4 are provided with a first discontinuous mark, and the teeth of the first rack segment are provided with a second discontinuous mark. When the rotating gear 4 is in contact with the first rack segment, the first discontinuous mark and the second discontinuous mark constitute a continuous mark.

[0123] For example, the first discontinuous marker is an incomplete graphic, and the second discontinuous marker is also an incomplete graphic. When the rotating gear 4 aligns with the first rack segment, the two incomplete graphics can be joined together to form a complete graphic. In this way, the two incomplete graphics provide an indication of the engagement position between the rotating gear 4 and the first rack segment. This not only facilitates the operation of assembly personnel but also makes it easier to quickly determine the meshing state of the rotating gear 4 and the first rack segment during subsequent inspection and maintenance, thus improving maintenance efficiency.

[0124] Optionally, the first non-continuous identifier includes a first group of non-continuous numbers, and the second non-continuous identifier includes a second group of non-continuous numbers.

[0125] like Figure 13 As shown in B, the two sets of discontinuous numbers form a continuous set of numbers after the rotating gear 4 and the first rack segment come into contact. This allows for a quick determination of whether the two are properly aligned.

[0126] Optionally, when the air guide plate is in the closed state, the toothed portion 43 of the rotating gear 4 includes a meshing toothed portion 431 that meshes with the first rack segment, a first non-meshing toothed portion 432 disposed at one end of the meshing toothed portion 431, and a second non-meshing toothed portion 433 disposed at the other end of the meshing toothed portion 431. The meshing toothed portion 431 includes a first meshing tooth, the first rack segment includes a second meshing tooth and a third meshing tooth that mesh with the first meshing tooth, and the first meshing tooth is marked with a first direction, the second meshing tooth and the third meshing tooth are marked with a second direction, and the first direction is opposite to the second direction.

[0127] like Figure 13As shown in C, the first meshing tooth of the meshing tooth segment 431 is provided with an arrow pointing towards the first rack segment. Correspondingly, the second and third meshing teeth of the first rack segment are respectively provided with arrows pointing towards the meshing tooth segment 431. The arrow pointing towards the first direction is positioned between the two arrows pointing towards the second direction, thus completing the precise docking of the rotating gear 4 and the first rack segment.

[0128] Optionally, the number of teeth of the rotating gear 4 is n4, and the number of teeth of the first rack segment is n5, wherein n4 > n5; and / or, n4 ≤ 10; and / or, n5 ≤ 10; and / or, n4 + n5 ≤ 15.

[0129] In this embodiment, the number of teeth of the rotating gear 4 and the number of teeth of the first rack segment are both relatively small. This effectively reduces the volume of the rotating gear 4 and the first rack segment, thereby reducing the volume of the entire drive mechanism, saving installation space for the drive mechanism, and facilitating the miniaturization of the air conditioner indoor unit.

[0130] Optionally, the first connecting end 11 of the extended connecting rod 1 is provided with a motion limiting member 13, which abuts against the second connecting end 21 of the rotating connecting rod 2.

[0131] Although the rotating connecting rod 2 is equipped with a second sliding shaft 23 for limiting, the distance between the second sliding shaft 23 and the first rack segment is relatively large. When the arc-shaped first rack segment is subjected to the meshing force of the rotating gear 4, it is prone to deformation, increasing the clearance outward or disengaging from the gear, causing transmission errors. In this embodiment, a motion limiting member 13 is provided at the first connecting end 11 of the extended connecting rod 1. This motion limiting member 13 abuts against the second connecting end 21, thus limiting the deformation of the first rack segment and reducing transmission errors. Figure 14 As shown.

[0132] Optionally, the second connecting end 21 of the rotating link 2 includes a first rack segment, which is disposed on the driving side 211 of the second connecting end 21. The second connecting end 21 also includes an abutting side 212 opposite to the driving side 211, wherein the motion limiting member 13 abuts against the abutting side 212 of the second connecting end 21.

[0133] In this embodiment, the motion limiting member 13 abuts against the abutting side 212 of the second connecting end 21. Thus, the abutting side 212 of the extended or retracted second connecting end 21 is subjected to the abutting force of the motion limiting member 13, limiting the deformation of the first rack segment, reducing transmission error, and thereby improving the driving accuracy of the rotating connecting rod 2 on the air guide plate. Optionally, the abutting side 212 is straight. This improves the stability of the abutting between the motion limiting member 13 and the abutting side 212 during the extension and retraction of the rotating connecting rod 2.

[0134] Optionally, the motion limiting member 13 includes a support shaft. Optionally, the support shaft sleeve is provided with a sleeve capable of elastic deformation, such as a rubber sleeve.

[0135] Optionally, the first connecting end 11 of the extended connecting rod 1 includes a first pivot shaft, which is pivotally connected to the gear center 41 of the rotating gear 4, wherein the first pivot shaft is disposed opposite to the motion limiting member 13.

[0136] along Figure 6 As indicated by the middle arrow, the first pivot shaft is located at one end of the first connecting end 11, and the motion limiting member 13 is located at the other end of the first connecting end 11. In this way, the motion limiting member 13 is positioned approximately at the meshing position between the rotating connecting rod 2 and the rotating gear 4, thereby improving the contact stability of the motion limiting member 13 with the first rack segment of the rotating connecting rod 2.

[0137] Optionally, the drive mechanism further includes a first drive box 5 and a second drive box 6. The first drive box 5 is provided with a first track 51 and a third track 52, and the extended connecting rod 1 moves along the first track 51 and the third track 52; the second drive box 6 is provided with a second track 61 and a fourth track 62, and the rotating connecting rod 2 moves along the second track 61 and the fourth track 62; the extended connecting rod 1 is provided with a first sliding shaft 14, which slides along the first track 51 and the third track 52; the rotating connecting rod 2 is provided with a second sliding shaft 23, which slides along the second track 61 and the fourth track 62.

[0138] The first sliding shaft 14 of the extending connecting rod 1 slides along the first track 51 and the third track 52. This can be understood as, under the driving action of the crank, the first sliding shaft 14 of the extending connecting rod 1 first slides along the first track 51 and then slides along the third track 52. Similarly, the second sliding shaft 23 of the rotating connecting rod 2 slides along the second track 61 and the fourth track 62. This can be understood as, under the driving action of the crank, the second sliding shaft 23 of the rotating connecting rod 2 first slides along the second track 61 and then slides along the fourth track 62.

[0139] Optionally, the first track 51, the second track 61, the third track 52 and the fourth track 62 are all grooved tracks, which improves the stability of the first sliding shaft 14 and the second sliding shaft 23 sliding within the tracks and makes them less prone to slippage.

[0140] Optionally, the first drive box 5 and the second drive box 6 are fixedly connected to the body of the indoor unit of the air conditioner, thereby allowing the entire drive mechanism to be installed in the indoor unit of the air conditioner.

[0141] Optionally, the drive element 3 includes a crank, which includes a first crankshaft 31 and a second crankshaft 32. The first crankshaft 31 is driven to the extended connecting rod 1 so that the crank drives the extended connecting rod 1 to move.

[0155] Optionally, the first connecting end 11 of the extended link 1 includes a first corner position, wherein the first limiting block 151 is disposed at the first corner position.

[0156] The first connecting end 11 of the extended connecting rod 1 includes a first corner position with a bend.

When the air guide plate opens in the first direction, the first limiting block 151 abuts against the first end tooth 461.

[0158] like Figure 16 and Figure 33 As shown, when the air guide plate opens to its maximum angle in the first direction, the first end tooth 461 of the rotating gear 4 abuts against the first limiting block 151. This improves the accuracy of the air guide angle of the air guide plate rotation.

[0164] Optionally, the driving element 3 drives the extension link 1 to move along the third track 52 and drives the rotating link 2 to move along the fourth track 62, so as to drive the air guide plate to open in the second direction. When the air guide plate opens in the second direction, the second limiting block 152 abuts against the second end tooth 462.

[0165] like Figure 17 and Figure 35 As shown, when the air guide plate opens to its maximum angle in the second direction, the second end tooth 462 of the rotating gear 4 abuts against the second limit stop 152. This improves the accuracy of the air guide angle of the air guide plate rotation.

[0167] Optionally, the extending link 1 is provided with a first sliding shaft 14 that slides along the first track 51, and the rotating link 2 is provided with a second sliding shaft 23 that slides along the second track 61.

[0168] The first sliding shaft 14 of the extending connecting rod 1 slides along the first track 51 of the first drive box 5, thus causing the extending connecting rod 1 to abut against the first drive box 5 during the sliding process, providing a mounting carrier for the extending connecting rod 1; the second sliding shaft 23 of the rotating connecting rod 2 slides along the second track 61 of the second drive box 6, thus causing the rotating connecting rod 2 to abut against the second drive box 6 during the sliding process, providing a mounting carrier for the rotating connecting rod 2. It can be seen that in the drive mechanism provided in this embodiment, the first drive box 5 and the second drive box 6 respectively limit the movement of the extending connecting rod 1 and the rotating connecting rod during the sliding process.

[0169] Optionally, the rotating link 2 is further provided with a first sliding abutment post 241, wherein the first sliding abutment post 241 slides against the extended link 1.

[0171] The first sliding shaft 14 is disposed on the first protruding rod surface of the protruding connecting rod 1, and the second protruding rod surface of the protruding connecting rod 1 abuts against the first sliding abutment post 241. In this way, the first sliding shaft 14 and the first sliding abutment post 241 limit the protruding connecting rod 1 in the left and right directions during the sliding process, thereby improving the motion stability of the protruding connecting rod 1.

[0172] Optionally, the extended link 1 includes a link bottom surface 161 and a link edge protruding upward from the link bottom surface 161, wherein the first sliding abutment post 241 abuts against the link edge.

[0173] The edge of the extended link 1 is a smooth, flush surface.

In this way, both the second sliding abutment post 242 and the first sliding abutment post 241 of the rotating link 2 abut against the extended link 1, which improves the abutment stability between the rotating link 2 and the extended link 1.

[0176] A sliding abutment groove 17 is provided on the second protruding rod surface of the protruding connecting rod 1, and the sliding abutment groove 17 is in the shape of a groove. As the protruding connecting rod 1 and the rotating connecting rod 2 slide, the second sliding abutment post 242 slides within the sliding abutment groove 17.

[0178] like Figure 18 As shown, a perpendicular line is drawn from the edge of the second sliding abutment post 242, and the first sliding abutment post 241 is located behind this perpendicular line. That is, the first abutment height of the first sliding abutment post 241 is less than the second abutment height of the second sliding abutment post 242, which improves the abutment stability between the two sliding abutment posts of the rotating link 2 and the extended link 1.

[0179] Optionally, the rotating connecting rod 2 includes a second slide rail 221 and a fourth slide rail 222 spaced apart, the driving element 3 includes a second crankshaft 32 and a fourth crankshaft 34, and the second crankshaft 32 slides along the second slide rail 221 and the fourth crankshaft 34 slides along the fourth slide rail 222.

[0180] The crank is driven to connect with the rotating connecting rod 2, and the crank exerts a driving force on the rotating connecting rod 2. In this embodiment, the first sliding abutment post 241 is disposed between the second slide rail 221 and the fourth slide rail 222, which improves the motion stability of the rotating connecting rod 2 during the drive connection between the crank and the rotating connecting rod 2, and at the same time avoids motion interference between the first sliding abutment post 241 and the crank.

[0181] Furthermore, the rotating gear 4 meshes with the rotating connecting rod 2, generating a meshing force between them. In this embodiment, the second sliding abutment post 242 is disposed between the fourth slide rail 222 and the second connecting end 21, reducing the wobbling of the second connecting end 21 of the rotating connecting rod 2, improving the motion stability of the rotating connecting rod 2 during the meshing connection of the rotating gear 4 and the rotating connecting rod 2, and at the same time avoiding motion interference between the second sliding abutment post 242 and the rotating gear 4.

[0182] Optionally, the first drive box 5 includes a first drive bottom surface 501 and a first drive edge 502 protruding upward from the first drive bottom surface 501, and the second drive box 6 includes a second drive bottom surface 601 and a second drive edge 602 protruding upward from the second drive bottom surface 601. The first track 51 is disposed on the first drive bottom surface 501, the second track 61 is disposed on the second drive bottom surface 601, and the first drive edge 502 and the second drive edge 602 are fastened together.

[0183] After the first drive box 5 and the second drive box 6 are engaged, the first drive edge 502 and the second drive edge 602 are also engaged and connected. In this way, the first drive box 5 and the second drive box 6 limit the extension link 1 and the rotation link 2. Optionally, the first drive edge 502 and the second drive edge 602 are fixedly connected by means of slots, buckles, or screws.

[0184] Optionally, the first drive box 5 and the second drive box 6 are fastened together to form a connecting rod extension cavity, wherein a connecting rod extension port 603 is provided at the bottom of the connecting rod extension cavity.

[0185] The extension connecting rod 1, the rotating connecting rod 2, and the crank are all housed within the connecting rod extension cavity formed after the first drive box 5 and the second drive box 6 are engaged, making the entire drive mechanism more compact. Furthermore, a connecting rod extension port 603 is provided at the bottom of this connecting rod extension cavity, through which the extension connecting rod 1 and the rotating connecting rod 2 connect to the air guide plate during the extension and retraction process.

[0186] Optionally, the drive mechanism also includes an extension cover 8. The extension cover 8 is engaged with the first connecting end 11 of the extension link 1, wherein the extension cover 8 and the first connecting end 11 of the extension link 1 form a shielding cavity, and the connecting piece of the air guide plate and the second connecting end 21 of the rotating link 2 are disposed in the shielding cavity.

[0187] In this embodiment, the protruding cover 8 and the first connecting end 11 of the protruding connecting rod 1 form a shielding cavity, and the rotating gear 4 and the first rack segment of the rotating connecting rod 2 are both disposed within this shielding cavity. It can be seen that the protruding cover 8 provides shielding for the rotating gear 4 and the first rack segment, improving the overall aesthetics of the drive mechanism during the driving process.

[0188] Optionally, the extended link 1 includes a link bottom surface 161 and a link edge protruding upward from the link bottom surface 161. The link edge includes a first link edge 162 of the first connecting end 11, wherein the protruding edge of the extended cover 8 engages with the first link edge 162 of the extended link 1.

[0189] The first connecting rod edge 162 located at the first connecting end 11 of the extending connecting rod 1 engages with the protruding edge of the extending cover 8. For example, the two can be engaged in the form of a slot and a buckle, which improves the connection stability between the two and improves the shielding effect of the extending cover 8 on the rotating gear 4 and the first rack segment.

[0190] Optionally, the connecting component of the air guide plate includes a rotating gear 4. The rotating gear 4 includes a first gear mounting end 44 disposed at one end of the rotating circumferential surface and a second gear mounting end 45 disposed at the other end of the rotating circumferential surface. The first gear mounting end 44 is pivotally connected to the first connecting end 11 of the extended connecting rod 1, and the second gear mounting end 45 is used to connect with the air guide plate. The extended cover 8 is provided with a through mounting hole 81, and the second gear mounting end 45 of the rotating gear 4 passes through the through mounting hole 81 to connect with the air guide plate.

[0191] The through mounting hole 81 extends through the body of the protruding cover 8, and the second gear mounting end 45 of the rotating gear 4 passes through the through mounting hole 81 and connects to the air guide plate body 7. It can be seen that the through mounting hole 81 provides space for the installation of the rotating gear 4 and the air guide plate body 7. Optionally, the diameter of the through mounting hole 81 is slightly larger than the diameter of the second gear mounting end 45, thus ensuring that the second gear mounting end 45 can rotate normally.

[0192] Optionally, the first rotating surface of the rotating link 2 includes a limiting guide end 25, and the limiting guide end 25 is provided with a second sliding shaft 23. The second sliding shaft 23 slides along the second track 61 and the fourth track 62. A link step 26 is provided between the limiting guide end 25 and the second connecting end 21 of the rotating link 2. The limiting guide end 25 is located at one end of the higher step of the link step 26, and the second connecting end 21 is located at one end of the lower step of the link step 26.

[0193] like Figure 27 As shown, the first rotating surface of the rotating link 2 is stepped, with a link step 26. A limiting guide end 25 is located at one end of the higher step of the link step 26, and a second connecting end 21 is located at one end of the lower step of the link step 26. Thus, the protruding cover 8 is located at the lower step of the rotating link 2, reducing the overall size of the drive mechanism. Optionally, when the protruding cover 8 is engaged with the protruding link 1, the protruding cover 8 is flush with the higher step of the rotating link 2.

[0194] Optionally, when the air guide plate opens in the second direction, a reserved gap is provided between the connecting rod step 26 of the rotating connecting rod 2 and the protruding cover 8.

[0195] When the air guide plate opens in the second direction, the distance between the connecting rod step 26 of the rotating connecting rod 2 and the extension cover 8 is the closest. In this embodiment, when the air guide plate opens in the second direction, a reserved gap is still left between the connecting rod step 26 and the extension cover 8, so that the setting of the extension cover 8 does not interfere with the extension or retraction movement of the rotating connecting rod 2.

[0196] Optionally, the first drive box 5 and the second drive box 6 are fastened together to form a connecting rod extension cavity. The bottom of the connecting rod extension cavity is provided with a connecting rod extension port 603. When the air guide plate is opened in the second direction, at least a portion of the extension cover 8 is located inside the connecting rod extension cavity.

[0197] When the air guide plate opens in the second direction, the portion of the protruding cover 8 exposed outside the connecting rod extension cavity is the largest. In this embodiment, when the air guide plate opens in the second direction, the protruding cover 8 is still at least partially located inside the connecting rod extension cavity, improving the shielding effect of the protruding cover 8 on the rotating gear 4 and the first rack segment. Figure 24 As shown.

[0198] This disclosure also provides an indoor air conditioning unit.

[0199] Optionally, the indoor unit of the air conditioner includes an air guide vane and an air guide vane drive mechanism for driving the air guide vane to rotate.

[0200] Optionally, the connecting component of the air guide plate includes a rotating gear 4 and a mounting base 71 disposed on the air guide plate body 7, and the rotating gear 4 and the mounting base 71 are connected via an adapter 72, which is detachably connected to the mounting base 71.

[0201] The rotating gear 4 is directly fixedly connected to the adapter 72, and the adapter 72 is directly fixedly connected to the mounting base 71. The rotation of the rotating gear 4 is transmitted to the mounting base 71 of the air guide plate body 7 through the adapter 72, thereby driving the air guide plate body 7 to rotate.

[0202] In this embodiment, the rotating gear 4 is indirectly connected to the mounting base 71 of the air guide plate body 7 via the adapter 72, and the adapter 72 is detachably connected to the mounting base 71. In this way, when the air guide plate body 7 needs to be disassembled, the drive mechanism does not need to be disassembled, which improves the ease of assembly of the air guide plate body 7.

[0203] Optionally, the rotating gear 4 includes a first gear mounting end 44 disposed at one end of the rotating circumferential surface and a second gear mounting end 45 disposed at the other end of the rotating circumferential surface. The first gear mounting end 44 is pivotally connected to the first connecting end 11 of the extended connecting rod 1, wherein the adapter 72 is connected to the second gear mounting end 45 of the rotating gear 4.

[0204] The adapter 72 is directly connected to the second gear mounting end 45. Optionally, the second gear mounting end 45 of the rotating gear 4 includes a limiting snap-fit ​​assembly, and the adapter 72 includes a limiting snap-fit ​​hole 721, wherein the limiting snap-fit ​​assembly is snapped into the limiting snap-fit ​​hole 721.

[0205] The limiting snap-fit ​​assembly can be an elastic snap-fit, optionally in the form of a cross-shaped snap-fit. Correspondingly, the limiting snap-fit ​​hole 721 is also in the form of a cross-shaped snap-fit. This improves the connection stability between the limiting snap-fit ​​assembly and the limiting snap-fit ​​hole 721 and the uniformity of force during the snap-fit ​​rotation process.

[0206] Optionally, the rotary gear 4 has a gear center 41, and the limiting snap-fit ​​assembly includes a snap-fit ​​center, wherein the gear center 41 and the snap-fit ​​center are located on the same horizontal line.

[0207] The gear center 41 of the rotating gear 4 and the locking center of the limiting locking assembly are located on the same horizontal line. This ensures that the rotation of the rotating gear 4 can be accurately transmitted to the adapter 72 through the limiting locking assembly, and then to the air guide plate body 7, thereby improving the accuracy of driving the air guide plate body 7.

[0208] Optionally, the mounting base 71 includes an outer shielding surface 712 and an inner mounting surface 711 opposite to the outer shielding surface 712. The inner mounting surface 711 is provided with a first limiting cavity 7111. The upper end of the adapter 72 is provided on the mounting boss 722, and the mounting boss 722 is provided in the first limiting cavity 7111.

[0209] When the air guide plate is open, the outer shielding surface 712 of the mounting base 71 faces the user directly, and the inner mounting surface 711 of the mounting base 71 is used to connect with the adapter 72. Optionally, the shape and size of the first limiting cavity 7111 of the inner mounting surface 711 match the mounting boss 722 of the adapter 72, thereby restricting the vertical movement of the adapter 72.

[0210] Optionally, the mounting base 71 further includes a snap-fit ​​protrusion 7112 disposed at the lower part of the first limiting cavity 7111, and the lower end of the adapter 72 is provided with a buckle 723, wherein the buckle 723 of the adapter 72 is snapped into the snap-fit ​​protrusion 7112.

[0211] The lower end of the adapter 72 has an integrally formed buckle 723, and the lower part of the mounting base 71 has an integrally formed snap-fit ​​protrusion 7112. The elastic buckle 723 engages with the snap-fit ​​protrusion 7112. Optionally, the side of the buckle 723 of the connector is provided with a raised rib 724. For example, each of the two elastic buckles 723 is provided with a raised rib 724, which restricts the left-right movement of the adapter 72.

[0212] When it is necessary to disassemble the air guide plate body 7, bring the two protruding ribs 724 together so that the buckle 723 disengages from the snap-fit ​​protrusion 7112, and then the air guide plate body 7 can be disassembled.

[0213] Optionally, a first preset gap is provided between the first gear mounting end 44 and the extension connecting rod 1; and / or, the air guide plate driving mechanism further includes an extension cover 8, which is engaged with the first connecting end 11 of the extension connecting rod 1. The extension cover 8 and the first connecting end 11 of the extension connecting rod 1 form a shielding cavity. The connecting piece of the air guide plate and the second connecting end 21 of the rotating connecting rod 2 are disposed in the shielding cavity. The extension cover 8 is provided with a through mounting hole 81. The second gear mounting end 45 of the rotating gear 4 passes through the through mounting hole 81 and is connected to the air guide plate. Furthermore, a second preset gap is provided between the second gear mounting end 45 and the extension cover 8.

[0214] Because the length of the air guide plate body 7 in the left-right direction is relatively long, the error of the air guide plate body 7 itself is relatively large. However, the installation positions of the two drive mechanisms on the left and right sides of the air guide plate body 7 are fixed. The air guide plate body 7 of different lengths has a significant impact on the operation of the drive mechanism, which will cause the extension link 1 and the rotating link 2 to offset and wear in the left-right direction. Therefore, a first preset gap and a second preset gap are provided on both sides of the rotating gear 4 to reduce the impact of the dimensional error of the air guide plate body 7 in the left-right direction on the drive mechanism. In this way, the left and right positions of the extension link 1 and the rotating link 2 are not affected by the dimensional error in the length direction of the air guide plate body 7.

[0215] Optionally, the first preset gap is 0.5~1mm; similarly, the second preset gap is 0.5~1mm.

[0216] like Figure 31 As shown, when the air guide plate is in the closed state, the meshing tooth segment 431 of the rotating gear 4 meshes with the first rack segment, and the first crankshaft 31 of the crank is located at the port position of the first slide 121 of the extending connecting rod 1, and the third crankshaft 33 of the crank is located at the port position of the second slide 221 of the rotating connecting rod 2; the first sliding shaft 14 of the extending connecting rod 1 is located at the C1 position of the first track 51, and the second sliding shaft 23 of the rotating connecting rod 2 is located at the D1 position of the second track 61.
