[0071] 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.

[0072] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0073] Combine Figure 1-34 As shown, the embodiment of the present disclosure provides a driving device for an air guide plate of an air conditioner. The air conditioner includes an indoor unit 100 and an outdoor unit connected to the indoor unit 100. Figure 1 and Figure 34 As shown, the indoor unit 100 includes a housing 1001, an evaporator 1006, a fan 1005, and an air guide plate 1002. The housing 1001 defines an air duct 1003. The evaporator 1006 and the fan 1005 are disposed within the air duct 1003. The housing 1001 is provided with an air inlet and an air outlet 1004, both of which are connected to the air duct 1003. The air guide plate 1002 is disposed at the air outlet 1004. The fan 1005 drives air into the air duct 1003 through the air inlet. After exchanging heat with the evaporator 1006, the air is blown out of the air outlet 1004. The air guide plate 1002 is used to adjust the air outlet direction of the air outlet 1004. That is, when the air guide plate 1002 is in different air guide positions, the air outlet 1004 has different air outlet directions.

[0074] like Figure 16 As shown, the driving device for the air guide plate of the air conditioner includes a first connecting rod 1, a second connecting rod 2 and a rotating member 4.

[0075] The first connecting rod 1 is configured to be movably connected to the wind guide plate 1002; the second connecting rod 2 is configured to be movably connected to the wind guide plate 1002; the rotating member 4 is controlled to rotate and is driven to be connected to both the first connecting rod 1 and the second connecting rod 2 to drive the wind guide plate 1002 to open and close; wherein, during the opening process of the wind guide plate 1002, the first connecting rod 1 first moves along the first trajectory A1A3, then moves forward along the second trajectory A3A5, and then moves reversely along the second trajectory. The line connecting the starting point A1 and the end point A3 of the first trajectory (a straight line) and the line connecting the starting point A3 and the end point A5 of the second trajectory (a straight line) are not on the same straight line.

[0076] During the continuous opening of the air guide plate 1002 from the closed position, the first connecting rod 1 first moves along the first trajectory, then moves forward along the second trajectory, and then moves reversely along the second trajectory. That is, the first connecting rod 1 moves reversely along the second trajectory, which can reduce the space occupied by the first connecting rod 1 due to movement.

[0077] The line connecting the starting point and the end point of the first trajectory and the line connecting the starting point and the end point of the second trajectory are not on the same straight line, so that when the first link 1 moves from the first trajectory to the second trajectory, the movement direction will be deflected. When the multiple air-guiding positions of the air guide plate 1002 are fixed, the deflection of the first link 1 is conducive to the flipping of the air guide plate 1002, which can simplify the connection method between the first link 1 and the air guide plate 1002, and the connection method between the second link 2 and the air guide plate 1002. For example, the first link 1 is an integrated structure and is directly connected to the air guide plate 1002 through a first rotating shaft, and the second link 2 is an integrated structure and is directly connected to the air guide plate 1002 through a second rotating shaft. The air guide plate 1002 can still have a cooling horizontal blowing position and a heating downward blowing position, as well as multiple air-guiding positions located between the cooling horizontal blowing position and the heating downward blowing position. In this way, the first connecting rod 1 and / or the second connecting rod 2 do not need to be slidably connected to the wind deflector 1002, nor is there any need to add a crank between the first connecting rod 1 and the wind deflector 1002 or between the second connecting rod 2 and the wind deflector 1002 as in the related art.

[0078] Optionally, the first trajectory includes a straight trajectory and / or a curved trajectory.

[0079] The first track may be a straight track, a curved track (such as a circular track or a non-circular track), or a combination of a straight track and a curved track.

[0080] The second trajectory includes a straight trajectory and / or a curved trajectory.

[0081] The second track can be a straight track, a curved track (such as a circular track or a non-circular track), a combination of a straight track and a curved track, or a combination of multiple straight track segments (such as a Figure 33 shown).

[0082] Optionally, at the starting point A1 of the first trajectory A1A3, the air guide plate 1002 is in a closed position, the end point A3 of the first trajectory coincides with the starting point A3 of the second trajectory in the positive direction, the end point of the first trajectory, the air guide plate 1002 is in one of the cooling horizontal blowing position and the heating downward blowing position, and at the end point A5 of the second trajectory in the positive direction, the air guide plate 1002 is in the maximum air supply position, and when the first connecting rod 1 moves in the opposite direction along the second trajectory, the air guide plate 1002 moves toward the other of the cooling horizontal blowing position and the heating downward blowing position.

[0083] During the opening process of the air guide plate 1002, the starting point of the positive movement of the second track coincides with the end point of the first track, and the end point of the positive movement of the second track is the end point of the second track that deviates from the first track. Figure 33As shown, the starting point of the first trajectory is A1 and the end point is A3, the starting point of the second trajectory in the positive direction is A3 and the end point in the positive direction is A5. During the opening process of the air guide plate 1002, the first connecting rod 1 moves from A1 to A3 along the first trajectory, then moves forward along the second trajectory from A3 to A5, and then moves in the opposite direction along the second trajectory from A5 toward A3.

[0084] At the end point A3 of the first trajectory, the air guide plate 1002 is in the cooling horizontal blowing position. At the end point A5 of the second trajectory in the forward direction, the air guide plate 1002 is in the maximum air supply position. When the first connecting rod 1 moves in the reverse direction along the second trajectory, the air guide plate 1002 moves toward the heating downward blowing position. Alternatively, at the end point A3 of the first trajectory, the air guide plate 1002 is in the heating downward blowing position. At the end point A5 of the second trajectory in the forward direction, the air guide plate 1002 is in the maximum air supply position. When the first connecting rod 1 moves in the reverse direction along the second trajectory, the air guide plate 1002 moves toward the cooling horizontal blowing position.

[0085] Optionally, the driving device for the air guide plate further comprises a motor 5, which is connected to the rotating member 4 and drives the rotating member 4 to rotate. When the air guide plate 1002 is opened, the rotating member 4 rotates unidirectionally, that is, the output shaft of the motor 5 also rotates unidirectionally.

[0086] During the opening process of the air guide plate 1002, the output shaft of the motor 5 rotates unidirectionally, driving the rotating part 4 to rotate unidirectionally. The unidirectional rotation of the rotating part 4 drives the first connecting rod 1 to move in the opposite direction along the second trajectory, thereby simplifying the control of the motor 5 and meeting the requirements for the motion trajectory of the first connecting rod 1.

[0087] Alternatively, as Figure 9 and Figure 17 As shown, one of the first connecting rod 1 and the rotating member 4 is provided with a first column structure, and the other is provided with a first groove structure. The first column structure is located in the first groove structure and can slide relative to the first groove structure to drive the first connecting rod 1 to move, wherein the first groove structure is a non-circular curved groove, and there is no circular groove section on the first groove structure.

[0088] The first connecting rod 1 is provided with a first column structure, and the rotating member 4 is provided with a first groove structure, or the first connecting rod 1 is provided with a first groove structure, and the rotating member 4 is provided with a first column structure.

[0089] The first column structure slides relative to the first slot structure, applying a driving force to the first slot structure, thereby driving the movement of the first connecting rod 1. The shape of the first slot structure can change the magnitude and / or direction of the driving force, thereby changing the movement trajectory of the first connecting rod 1.

[0090] The first groove structure is a non-circular curved groove, which can enable the first connecting rod 1 to move along the first track and the second track during the opening of the wind guide plate 1002, and the line connecting the starting point and the end point of the first track and the line connecting the starting point and the end point of the second track are not on the same straight line.

[0091] Alternatively, as Figure 33 As shown, during the opening process of the air guide plate 1002, when the first link 1 moves along the first trajectory A1A3, the second link 2 moves along the third trajectory B1B3, and when the first link 1 moves forward along the second trajectory A3A5, the second link 2 moves along the fourth trajectory B3B5, wherein the line connecting the starting point B1 and the end point B3 of the third trajectory (a straight line) and the line connecting the starting point B3 and the end point B5 of the fourth trajectory (a straight line) do not coincide with each other, and the third trajectory and the fourth trajectory are arranged in sequence along the length direction of the air duct 1003.

[0092] like Figure 33 As shown, the starting point of the third track is B1 and the end point is B3. The starting point of the fourth track is B3, which coincides with the end point of the third track. The end point of the fourth track is B5.

[0093] During the opening process of the air guide plate 1002, when the first link 1 moves to point A1, the second link 2 moves to point B1; when the first link 1 moves to point A3, the second link 2 moves to point B3; when the first link 1 moves to point A5, the second link 2 moves to point B5.

[0094] The line connecting the starting point and the end point of the third track B1B3 does not coincide with the line connecting the starting point and the end point of the fourth track B3B5, that is, the second connecting rod 2 needs to be deflected when turning from the third track to the fourth track, so as to facilitate the flipping of the wind guide plate 1002.

[0095] The third track and the fourth track are sequentially arranged along the length direction of the air duct 1003 , that is, when the second connecting rod 2 moves along the third track and the fourth track, it continuously extends out of the air duct 1003 .

[0096] The third trajectory includes a straight trajectory and / or a curved trajectory.

[0097] The third track can be a straight track, a curved track (such as a circular arc track or a non-circular arc track), a combination of a straight track and a curved track, or a broken line including multiple straight lines (such as a Figure 33 shown).

[0098] The fourth track BB5 includes a straight track and / or a curved track.

[0099] The fourth track can be a straight track, a curved track (such as a circular arc track or a non-circular arc track), a combination of a straight track and a curved track, or a broken line including multiple straight lines (such as a Figure 33 shown).

[0100] Alternatively, as Figure 33 As shown, during the opening process of the wind guide plate 1002, when the first link 1 moves in the opposite direction along the second trajectory (that is, the first link 1 moves from the positive end point A5 of the second trajectory toward the positive starting point A3), the second link 2 moves along the fifth trajectory B5B6, wherein the angle formed by the line connecting the starting point B5 and the end point B6 of the fifth trajectory (a straight line) and the line connecting the starting point B3 and the end point B5 of the fourth trajectory BB5 (a straight line) is less than 90°.

[0101] When the first connecting rod 1 moves in the opposite direction along the second trajectory, the air guide plate 1002 continues to open from the maximum air supply position.

[0102] The first track A1A3 and the second track A3A5 are arranged sequentially along the length of the air duct 1003. Thus, when the air deflector 1002 is opened, the first connecting rod 1 moves along the first track and then moves forward along the second track, substantially extending out of the air duct 1003. When the first connecting rod 1 moves in the reverse direction along the second track, it retracts into the air duct 1003. Because the relative positions of the first and second rotation axes are fixed, the second connecting rod 2 also undergoes a partial movement, retracting into the air duct 1003. Therefore, the angle formed by the line B5B6 connecting the starting point and end point of the fifth track and the line B3B5 connecting the starting point and end point of the fourth track is less than 90°. The starting point of the fifth track is B5 and the end point is B6, while the starting point of the fourth track is B3 and the end point is B5.

[0103] The fifth track B5B6 can be a straight track, a curved track (such as a circular track or a non-circular track), or a combination of a straight track and a curved track. Figure 33 , the fifth trajectory is a non-circular curved trajectory.

[0104] Optionally, one of the second connecting rod 2 and the rotating member 4 is provided with a second column structure, and the other is provided with a second groove structure. The second column structure is located in the second groove structure and can slide relative to the second groove structure to drive the second connecting rod 2 to move. The second groove structure is a non-circular curved groove. The second groove structure is curved and there is no circular groove section on it.

[0105] The second connecting rod 2 is provided with a second column structure, and the rotating member 4 is provided with a second slot structure, or the second connecting rod 2 is provided with a second slot structure, and the rotating member 4 is provided with a second column structure.

[0106] The second column structure slides relative to the second slot structure, applying a driving force to the second slot structure, thereby driving the movement of the second connecting rod 2. The shape of the second slot structure can change the magnitude and / or direction of the driving force, thereby changing the movement trajectory of the second connecting rod 2.

[0107] The second groove structure is a non-arc-shaped curved groove, that is, it does not include an arc-shaped groove segment, which can enable the second connecting rod 2 to move along the third track, the fourth track and the fifth track in sequence during the opening process of the wind guide plate 1002, and the line connecting the starting point and the end point of the third track, the line connecting the starting point and the end point of the fourth track, and the line connecting the starting point and the end point of the fifth track are not on the same straight line.

[0108] like Figure 33 As shown, when the air guide plate 1002 opens from the closed position to the first open position, the first link 1 moves along the first trajectory A1A3, and the second link 2 moves along the third trajectory B1B3. The first trajectory A1A3 has a first intermediate point A2, and the third trajectory B1B3 has a second intermediate point B2 corresponding to A1, that is, when the first link 1 moves to the A2 position, the second link 2 moves to the B2 position.

[0109] The angle between the line L1 (a straight line) connecting points A1 and A2 and the line L2 (a straight line) connecting points B1 and B2 is smaller than the angle between the line L3 (a straight line) connecting points A1 and A3 and the line L2 (a straight line) connecting points B1 and B2, that is, compared with the line connecting points A1 and A3, the directions of the line connecting points A1 and A2 and the line connecting points B1 and B2 are closer to the same. In this way, when the air guide plate 1002 moves from the closed position to the first open position, the movement directions of the first connecting rod 1 and the second connecting rod 2 are closer to the same, and the air guide plate 1002 will not rotate at a large angle due to the large difference in the movement directions of the first connecting rod 1 and the second connecting rod 2, which can prevent the air guide plate 1002 from rotating prematurely, and further prevent the air guide plate 1002 from interfering with the housing 1001. Among them, A1 and A3 are the starting point and end point of the first trajectory, respectively, and B1 and B3 are the starting point and end point of the third trajectory, respectively.

[0110] Optionally, A2 divides the first trajectory into a first sub-trajectory A1A2 and a second sub-trajectory A2A3, and the first sub-trajectory A1A2 and the second sub-trajectory A2A3 are sequentially arranged along the length of the air duct 1003. B2 divides the third trajectory into a third sub-trajectory B1B2 and a fourth sub-trajectory B2B3, and the third sub-trajectory B1B2 and the fourth sub-trajectory B2B3 are sequentially arranged along the length of the air duct 1003.

[0111] During the opening process of the air deflector 1002, when the first connecting rod 1 moves along the first sub-trajectory, the second connecting rod 2 moves along the third sub-trajectory. When the first connecting rod 1 moves along the second sub-trajectory, the second connecting rod 2 moves along the fourth sub-trajectory. The first sub-trajectory A1A2 and the second sub-trajectory A2A3 are sequentially arranged along the length of the air duct 1003, and the third sub-trajectory B1B2 and the fourth sub-trajectory B2B3 are sequentially arranged along the length of the air duct 1003. When the first connecting rod 1 moves along the first trajectory and the second connecting rod 2 moves along the third trajectory, the first connecting rod 1 and the second connecting rod 2 both extend generally toward the outside of the air duct 1003, thereby driving the air deflector 1002 to move away from the air outlet 1004.

[0112] When the first link 1 moves along the first sub-trajectory and the second link 2 moves along the third sub-trajectory, the movement directions of the first link 1 and the second link 2 are closer to the same, and the deflection angle β1 of the air guide plate 1002 is small; when the first link 1 moves along the second sub-trajectory and the second link 2 moves along the fourth sub-trajectory, the difference in movement directions of the first link 1 and the second link 2 increases, and the deflection angle β2 of the air guide plate 1002 is larger, and β2 is greater than β1.

[0113] Optionally, the first sub-trajectory A1A2 includes a straight line trajectory and / or a curved line trajectory; and / or the second sub-trajectory A2A3 includes a straight line trajectory and / or a curved line trajectory.

[0114] The first sub-trajectory can be a straight line trajectory (such as Figure 33 As shown in FIG), it can also be a curved track (such as a circular track or a non-circular track), or a combination of a straight track and a curved track. The second sub-track can be a straight track (such as Figure 33 It can also be a curved trajectory (such as a circular trajectory or a non-circular trajectory), or a combination of a straight trajectory and a curved trajectory.

[0115] Optionally, the third sub-trajectory B1B2 includes a straight track and / or a curved track; and / or the fourth sub-trajectory B2B3 includes a straight track and / or a curved track.

[0116] The third sub-trajectory can be a straight line trajectory (such as Figure 33 As shown in FIG), it can also be a curved track (such as a circular track or a non-circular track), or a combination of a straight track and a curved track. The fourth sub-track can be a straight track (such as Figure 33 It can also be a curved trajectory (such as a circular trajectory or a non-circular trajectory), or a combination of a straight trajectory and a curved trajectory.

[0117] When the first connecting rod 1 moves to the A2 position and the second connecting rod 2 moves to the B2 position, the air guide plate 1002 is located between the closed position and the first open position.

[0118] Alternatively, as Figure 33 As shown, in the process of the air guide plate 1002 continuing to open from the first open position to the second open position, the second connecting rod 2 moves along the fourth trajectory B3B5, and there is a third intermediate point B4 on the fourth trajectory B3B5. In the process of the air guide plate 1002 continuing to open from the second open position to the third open position, the second connecting rod 2 moves along the fifth trajectory B5B6, and the angle between the straight line segment B4B5 and the straight line segment B5B6 is greater than the angle between the straight line segment B3B5 and the straight line segment B5B6, wherein B3, B5, and B6 are the starting point of the fourth trajectory, the end point of the fourth trajectory, and the end point of the fifth trajectory, respectively, and B5 is both the end point of the fourth trajectory and the starting point of the fifth trajectory.

[0119] A third intermediate point B4 is set, and the angle between the straight line segment B4B5 (the line connecting B4 and B5 is a straight line) and the straight line segment B5B6 (the line connecting B5 and B6 is a straight line) is greater than the angle between the straight line segment B3B5 (the line connecting B3 and B5 is a straight line) and the straight line segment B5B6. In this way, when the second connecting rod 2 switches from moving along the fourth track to moving along the fifth track, the degree of deflection of the movement direction of the second connecting rod 2 can be reduced, making the movement of the second connecting rod 2 smoother.

[0120] Optionally, the first open position is one of the cooling horizontal blowing position and the heating downward blowing position, the second open position is the maximum air supply position, and the third open position is the other one of the cooling horizontal blowing position and the heating downward blowing position.

[0121] At the end of the first trajectory, when the air guide plate 1002 is in the cooling horizontal blowing position, the first open position is the cooling horizontal blowing position, the second open position is the maximum air supply position, and the third open position is the heating downward blowing position; at the end of the first trajectory, when the air guide plate 1002 is in the heating downward blowing position, the first open position is the heating downward blowing position, the second open position is the maximum air supply position, and the third open position is the cooling horizontal blowing position.

[0122] Optionally, the included angle between the straight line segment B3B5 and the straight line segment B5B6 is an acute angle.

[0123] The extension direction of the straight line segment B3B5 is roughly the direction of extending out of the air duct 1003, and the extension direction of the straight line segment A3A5 is also roughly the direction of extending out of the air duct 1003. During the process of the air guide plate 1002 continuing to open from the first open position to the second open position, the first connecting rod 1 moves in the forward direction (from A3 to A5) along the second trajectory A3A5, and the second connecting rod 2 moves along the fourth trajectory B3B5. The first connecting rod 1 and the second connecting rod 2 move roughly in the direction of extending out of the air duct 1003, thereby ensuring that the relative position of the first rotation axis and the second rotation axis remains unchanged. During the process of the air guide plate 1002 continuing to open from the second open position to the third open position, the first connecting rod 1 moves in the reverse direction (from A5 to A3) along the second trajectory A3A5, that is, moves in the direction of retracting into the air duct 1003. Since the angle between the straight line segment B3B5 and the straight line segment B5B6 is an acute angle, the second connecting rod 2 also has a sub-movement in the direction of retracting into the air duct 1003, thereby ensuring that the relative position of the first rotation axis and the second rotation axis remains unchanged. Among them, A3 and A5 are the starting point and end point of the second trajectory respectively

[0124] Optionally, the fourth trajectory B3B5 includes a straight trajectory and / or a curved trajectory.

[0125] The fourth track can be a straight track, a curved track (such as a circular arc track or a non-circular arc track), a combination of a straight track and a curved track, or a broken line track including multiple straight lines (such as Figure 33 shown).

[0126] The fifth track B5B6 includes a straight track and / or a curved track.

[0127] The fifth track may be a straight track, a curved track (such as a circular arc track or a non-circular arc track), or a combination of a straight track and a curved track.

[0128] Optionally, the third middle point B4 divides the fourth track B3B5 into a fifth sub-track B3B4 and a sixth sub-track B4B5, and the fifth sub-track B3B4 and the sixth sub-track B4B5 are sequentially arranged along the length direction of the air duct 1003.

[0129] In this way, when the air guide plate 1002 is opened, when the first connecting rod 1 moves along the fifth sub-track B3B4 and the sixth sub-track B4B5, the first connecting rod 1 generally extends outward from the air duct 1003, so that the air guide plate 1002 can move from the first open position to the second open position.

[0130] Optionally, the fifth sub-trajectory B3B4 includes a straight line trajectory and / or a curved line trajectory; and / or the sixth sub-trajectory B4B5 includes a straight line trajectory and / or a curved line trajectory.

[0131] The fifth sub-track can be a straight line track (such as Figure 33As shown in FIG), it can also be a curved track (such as a circular track or a non-circular track), or a combination of a straight track and a curved track. The sixth sub-track can be a straight track (such as Figure 33 It can also be a curved trajectory (such as a circular trajectory or a non-circular trajectory), or a combination of a straight trajectory and a curved trajectory.

[0132] Optionally, the second trajectory A3A5 has a fourth intermediate point A4 corresponding to the third intermediate point B4, and the fourth intermediate point A4 divides the second trajectory A3A5 into a seventh sub-trajectory A3A4 and an eighth sub-trajectory A4A5. When the air guide plate 1002 continues to open from the second open position to the third open position, the first connecting rod 1 moves in the opposite direction along the eighth sub-trajectory A4A5.

[0133] As the air deflector 1002 continues to open from the first open position to the second open position, the first connecting rod 1 moves in the forward direction (from A4 to A5) along the seventh sub-trajectory A3A4 and the eighth sub-trajectory A4A5, and the second connecting rod 2 moves in the fifth sub-trajectory B3B4 and the sixth sub-trajectory B4B5. As the air deflector 1002 continues to open from the second open position to the third open position, the first connecting rod 1 moves in the reverse direction (from A5 to A4) along the eighth sub-trajectory A4A5, and the second connecting rod 2 moves in the direction of the fifth trajectory B5B6. When the air deflector reaches the third open position, the first connecting rod 1 reaches A4 and the second connecting rod reaches B6.

[0134] The line connecting B3 and B4 (a straight line) and the line connecting B4 and B5 (a straight line) are not on the same straight line, and the line connecting A3 and A4 (a straight line) and the line connecting A4 and A5 (a straight line) are not on the same straight line, so as to ensure that the relative position of the first rotation axis and the second rotation axis remains unchanged.

[0135] The motion trajectory of each point on the first link 1 is the same, and the motion trajectory of each point on the second link 2 is the same. Therefore, the motion trajectory of the rotational connection A on the first link 1 and the wind deflector 1002 is the same as the motion trajectory of other points on the first link 1, and the motion trajectory of the rotational connection B on the second link 2 and the wind deflector 1002 is the same as the motion trajectory of other points on the second link 2. Figure 33 In the figure, the rotation connection A between the first connecting rod 1 and the air guide plate 1002 and the rotation connection B between the second connecting rod 2 and the air guide plate 1002 are taken as examples to illustrate the motion trajectories of the first connecting rod 1 and the second connecting rod 2.

[0136] When the air deflector 1002 is in the closed position, point A is in position A1 and point B is in position B1; as the air deflector 1002 moves toward the first open position, point A first moves along the first sub-trajectory A1A2, and point B first moves along the third sub-trajectory B1B2. When point A reaches A2, point B reaches B2, and then point A moves along the second sub-trajectory A2A3, and point B moves along the fourth sub-trajectory B2B3. When point A reaches A3, point B reaches B3, and the air deflector 1002 reaches the first open position. Subsequently, the air deflector 1002 moves toward the second open position, and point A first moves along the seventh sub-trajectory A3A4. Movement, B first moves along the fifth sub-trajectory B3B4, when A reaches A4, B reaches B4, then A moves along the eighth sub-trajectory A4A5 in the forward direction (from A4 to A5), and B moves along the sixth sub-trajectory B4B5; when A reaches A5, B reaches B5, and the air guide plate 1002 reaches the second open position; then the air guide plate 1002 moves toward the third open position, A moves along the eighth sub-trajectory A4A5 in the reverse direction (from A5 to A4), and B moves along the fifth trajectory B5B6, when A reaches A4, B reaches B6, and the air guide plate 1002 reaches the third open position.

[0137] The first groove structure includes a first sub-groove structure. When the air guide plate 1002 is opened from the closed position to the first open position, the first column structure is located in the first sub-groove structure and can slide relative to the first sub-groove structure, wherein the first sub-groove structure is a non-circular curved groove, that is, the first sub-groove structure does not include a circular groove segment.

[0138] The second groove structure includes a second sub-groove structure. When the air guide plate 1002 is opened from the closed position to the first open position, the second column structure is located in the second sub-groove structure and can slide relative to the second sub-groove structure, wherein the second sub-groove structure is a non-circular curved groove, that is, the second sub-groove structure does not include a circular groove segment.

[0139] The line L1 (a straight line) connecting points A1 and A2 does not overlap with the line L3 (a straight line) connecting points A1 and A3. That is, after the first connecting rod 1 moves from point A1 to point A2, it will be deflected when it continues to move from point A2 toward point A3. Correspondingly, after the second connecting rod 2 moves from point B1 to point B2, it will be deflected when it continues to move from point B2 toward point B3. The first sub-groove structure and the second sub-groove structure are both non-circular curved grooves. In this way, the driving force generated by the first column structure sliding within the first sub-groove structure and relative to the first sub-groove structure on the first connecting rod 1, and the driving force generated by the second column structure sliding within the second sub-groove structure and relative to the second sub-groove structure on the second connecting rod 2, can drive the first connecting rod 1 and the second connecting rod 2 to deflect at points A2 and B2, respectively.

[0140] The second column structure includes a first boss 46, a second boss 47 and a third boss 48, and the second sub-groove structure includes a first sub-drive groove 221 that cooperates with the first boss 46, a fifth sub-drive groove 234 that cooperates with the second boss 47, and a sixth sub-drive groove 242 that cooperates with the third boss 48.

[0141] The first slot structure includes a third sub-slot structure. When the air guide plate 1002 moves from the first open position to the second open position, the first column structure is located in the third sub-slot structure and can slide relative to the third sub-slot structure, wherein the third sub-slot structure is a non-circular curved slot.

[0142] The second slot structure includes a fourth sub-slot structure. When the air guide plate 1002 moves from the first open position to the second open position, the second column structure is located in the fourth sub-slot structure and can slide relative to the fourth sub-slot structure, wherein the fourth sub-slot structure is a non-circular curved slot.

[0143] The third sub-groove structure includes a second sub-transmission groove 122 that cooperates with the first transmission column 42, a fourth sub-transmission groove 132 that cooperates with the second transmission column 43, and a fifth sub-transmission groove 141 that cooperates with the third transmission column 44; the fourth sub-groove structure includes a second sub-drive groove 222 (specifically, the fourth power groove 2222) that cooperates with the first boss 46, a third sub-drive groove 231 that cooperates with the second boss 47, and a fifth power groove 2411 that cooperates with the third boss 48.

[0144] The line connecting points A3 and A4 (a straight line) does not overlap with the line connecting points A4 and A5 (a straight line). This means that after the first connecting rod 1 moves from point A3 to point A4, it will bend when it continues to move from point A4 toward point A5. Correspondingly, after the second connecting rod 2 moves from point B3 to point B4, it will bend when it continues to move from point B4 toward point B5. Both the third and fourth sub-groove structures are non-circular curved grooves. Thus, the driving force generated by the first column structure sliding relative to the third sub-groove structure within the third sub-groove structure on the first connecting rod 1, and the driving force generated by the second column structure sliding relative to the fourth sub-groove structure within the fourth sub-groove structure on the second connecting rod 2, can cause the first connecting rod 1 and the second connecting rod 2 to deflect at points A4 and B4, respectively.

[0145] like Figure 7 and Figure 18 As shown, the first connecting rod 1 is provided with a plurality of guide portions, and the driving device for the air guide plate of the air conditioner further includes a guide member 3, which is fixed to the housing 1001. The guide member 3 is provided with a plurality of guide matching portions that match the plurality of guide portions to guide the movement of the first connecting rod 1 so that the first connecting rod 1 moves along a preset trajectory.

[0146] The rotating member 4 rotates to drive the first connecting rod 1 to move, and the guide portion and the guide matching portion cooperate to drive the air guide plate 1002 to open and close.

[0147] The plurality of guide matching portions at least partially overlap, which can reduce the space occupied by the plurality of guide matching portions and reduce the size of the guide member 3 .

[0148] The guide member 3 comprises a mechanism box, which includes a body 31 and a cover 32 disposed over the body 31. The body 31 and cover 32 together define an installation space, within which the first connecting rod 1 and the second connecting rod 2 are at least partially located. The drive device for the air deflector of the air conditioner further comprises a motor 5, which is disposed outside the installation space and is drivingly connected to the rotating member 4 to rotate the rotating member 4, thereby moving the first connecting rod 1 between a position extending from the installation space and a position retracted therein.

[0149] The first connecting rod 1 and the second connecting rod 2 are arranged in sequence along the direction from the box body 31 to the box cover 32, and the guide matching part is provided on the wall surface of the box body 31 facing the first connecting rod 1, that is, on the inner wall surface of the box body 31, and the corresponding guide part is provided on the wall surface of the first connecting rod 1 facing the box body 31.

[0150] Optionally, one of the guide portion and the guide matching portion includes a guide groove 310 , and the other includes a guide post 11 , which is located in the guide groove and can slide relative to the guide groove.

[0151] The guide portion includes a guide post, and the guide matching portion includes a guide groove, or the guide portion includes a guide groove, and the guide matching portion includes a guide post.

[0152] The guide post and the guide groove are matched, and the guide post slides relative to the guide groove, thereby limiting the movement trajectory of the first connecting rod 1, so that the first connecting rod 1 moves according to a preset trajectory.

[0153] The shape of the guide groove is the same as the motion trajectory of the first connecting rod 1 .

[0154] Alternatively, as Figure 7 As shown, the guide groove includes a first mating section 313 and a second mating section 314. The second mating section 314 is connected to the first mating section 313. When the air deflector 1002 is opened, the guide post sequentially engages with the first mating section 313 and the second mating section 314, and the first mating section 313 and the second mating section 314 are parallel or the extension lines of the first mating section 313 and the second mating section 314 coincide with each other. The multiple guide posts include a first guide post 111 and a second guide post 112. The multiple guide grooves include a first guide groove 311 corresponding to the first guide post 111 and a second guide groove 312 corresponding to the second guide post 112. The first mating section 313 of the first guide groove 311 and the second mating section 314 of the second guide groove 312 can at least partially overlap along the length direction of the first mating section 313 or the second mating section 314.

[0155] The first guide column 111 is adapted to the first guide groove 311, and the second guide column 112 is adapted to the second guide groove 312, so that when the first guide column 111 is located in the first guide groove 311 and can slide relative to the first guide groove 311, and the second guide column 112 is located in the second guide groove 312 and can slide relative to the second guide groove 312, the first connecting rod 1 can be guided to move along a predetermined trajectory.

[0156] During the opening process of the air guide plate 1002, the first guide column 111 cooperates with the first matching section 313 and the second matching section 314 of the first guide groove 311 in sequence, that is, the first guide column 111 is first located in the first matching section 313 of the first guide groove 311 and moves relative to the first matching section 313, and the first guide column 111 is then located in the second matching section 314 of the first guide groove 311 and moves relative to the second matching section 314, and the second guide column 112 cooperates with the first matching section 313 and the second matching section 314 of the second guide groove 312 in sequence, that is, the first guide column 111 is first located in the first matching section 313 of the second guide groove 312 and moves relative to the first matching section 313, and the first guide column 111 is then located in the second matching section 314 of the second guide groove 312 and moves relative to the second matching section 314.

[0157] like Figure 7 As shown, the first mating segment 313 and the second mating segment 314 are parallel or the extension lines of the first mating segment 313 and the second mating segment 314 coincide with each other, so that the first mating segment 313 of the first guide groove 311 and the second mating segment 314 of the second guide groove 312 can at least partially coincide with each other along the length direction of the first mating segment 313 or the second mating segment 314, rather than crossing each other, thereby further reducing the space occupied by the first guide groove 311 and the second guide groove 312.

[0158] Optionally, the first matching segment 313 and the second matching segment 314 have the same shape, which can increase the length of the overlapping portion of the first matching segment 313 of the first guide groove 311 and the second matching segment 314 of the second guide groove 312, further reducing the size of the guide member 3. Figure 7 As shown, the first matching segment 313 and the second matching segment 314 are both linear.

[0159] like Figure 7 As shown, the length of the first mating segment 313 is greater than the length of the second mating segment 314, and the starting point C1 of the first mating segment 313 of the first guide groove 311 coincides with the starting point D4 of the second mating segment 314 of the second guide groove 312, so as to increase the length of the overlapping portion of the first mating segment 313 of the first guide groove 311 and the second mating segment 314 of the second guide groove 312.

[0160] Alternatively, the length of the first mating segment 313 is smaller than the length of the second mating segment 314, and the end point of the first mating segment 313 of the first guide groove 311 coincides with the end point of the second mating segment 314 of the second guide groove 312, so as to increase the length of the overlapping portion between the first mating segment 313 of the first guide groove 311 and the second mating segment 314 of the second guide groove 312.

[0161] During the opening process of the air guide plate 1002 , the first guide column 111 moves from the starting point C1 of the first guide groove 311 toward the end point C5 .

[0162] Alternatively, as Figure 7 As shown, the second mating section 314 includes a first mating end 3141 and a second mating end 3142. The second mating end 3142 is disposed opposite the first mating end 3141. During the opening process of the air deflector 1002, the guide post first slides from the first mating end 3141 into the second mating end 3142, and then slides from the second mating end 3142 into the first mating end 3141. Specifically, during the opening process of the air deflector 1002, the first guide post 111 first slides from the first mating end 3141 on the second mating section 314 of the first guide groove 311 into the second mating end 3142, and then slides from the second mating end 3142 into the first mating end 3141. The second guide post 112 first slides from the first mating end 3141 on the second mating section 314 of the second guide groove 312 into the second mating end 3142, and then slides from the second mating end 3142 into the first mating end 3141.

[0163] The second fitting section 314 of the first guide groove 311 starts and ends at a first fitting end 3141 and a second fitting end 3142. The second fitting section 314 of the second guide groove 312 starts and ends at a first fitting end 3141 and a second fitting end 3142.

[0164] like Figure 7 As shown, the guide groove further includes a third matching segment 315, which is connected between the first matching segment 313 and the second matching segment 314, and the connections between the third matching segment 315 and the first matching segment 313 and the third matching segment 315 and the second matching segment 314 are both bent.

[0165] The guide groove further includes a fourth mating segment 316 , which is connected between the third mating segment 315 and the second mating segment 314 , and the connections between the fourth mating segment 316 and the third mating segment 315 and the fourth mating segment 316 and the second mating segment 314 are both bent.

[0166] like Figure 20 and Figure 21As shown, the second connecting rod 2 is provided with a guiding portion, and the box cover 32 is provided with a guiding matching portion. The number of the guiding portions and the guiding matching portions are also multiple and one-to-one corresponding. The multiple guiding portions cooperate with the multiple guiding matching portions to guide the movement trajectory of the second connecting rod 2.

[0167] One of the guiding portion and the guiding matching portion is the guiding groove 326 , and the other is the guiding post 21 . The guiding post 21 is located in the guiding groove 326 and can slide relative to the guiding groove 326 .

[0168] The shape of the guide groove 326 is the same as the motion trajectory of the second connecting rod 2 .

[0169] like Figure 21 As shown, the guide slot 326 includes a first guide segment 321 corresponding to the third sub-track, a second guide segment 322 corresponding to the third sub-track, a third guide segment 323 corresponding to the fifth sub-track, a fourth guide segment 324 corresponding to the sixth sub-track, and a fifth guide segment 325 corresponding to the fifth track. The shape of the first guide segment 321 is the same as that of the third sub-track, the shape of the second guide segment 322 is the same as that of the third sub-track, the shape of the third guide segment 323 is the same as that of the fifth sub-track, the shape of the fourth guide segment 324 is the same as that of the sixth sub-track, and the shape of the fifth guide segment 325 is the same as that of the fifth track.

[0170] The shapes of the first guide groove 311 and the second guide groove 312 are the same as the motion trajectory of the first connecting rod 1. Figure 7 As shown, corresponding to the points A1, A2, A3, A4 and A5 on the motion trajectory of the first connecting rod 1, the first guide groove 311 is provided with points C1, C2, C3, C4 and C5, and the second guide groove 312 is provided with points D1, D2, D3, D4 and D5. Figure 21 As shown, corresponding to points B1, B2, B3, B4, B5 and B6 on the second track, the guide groove 326 is provided with points E1, E2, E3, E4, E5 and E6.

[0171] When the air guide plate 1002 is in the closed position, Figure 3 and Figure 5 As shown, the first guide post 111 is located at position C1, and the second guide post 112 is located at position D1. As the air deflector 1002 moves toward the first open position, the first guide post 111 first moves along the first matching section 313 of the first guide groove 311, namely C1C2, and the second guide post 112 first moves along the first matching section 313 of the second guide groove 312, namely D1D2. The guide post 21 moves along the first guide section 321, namely E1E2. When the first guide post 111 reaches C2 and the second guide post reaches D2, the guide post 21 reaches E2, position A reaches A2, and position B reaches B2. Figure 12 and Figure 14As shown, the first guide post 111 then moves along the third matching section 315, namely C2C3, the second guide post 112 then moves along the third matching section 315, namely D2D3, and the guide post 21 moves along the second guide section 322, namely E2E3; when the first guide post 111 reaches C3, the second guide post 112 reaches D3, the guide post 21 reaches E3, point A reaches A3, and point B reaches B3, and the air deflector 1002 reaches the first open position; as shown in FIG. Figure 23 and Figure 26 As shown, the air guide plate 1002 then moves toward the second open position, the first guide post 111 first moves along the fourth matching section 316, namely C3C4, the second guide post 112 first moves along the fourth matching section 316, namely D3D4, and the guide post 21 moves along the third guide section 323, namely E3E4. When the first guide post 111 reaches C4, the second guide post 112 reaches B4, the guide post 21 reaches E4, A reaches A4, and B reaches B4. Then, the first guide post 111 moves along the second matching section 314, namely C4C5 in the positive direction (from C4 to C5), the second guide post 112 moves along the second matching section 314, namely D4D5 in the positive direction (from D4 to D5), and the guide post 21 moves along the fourth guide section 324, namely E4E5, wherein C4 and D4 are the first matching end portions 3141, and C5 and D5 are the second matching end portions 3142; as shown Figure 23 and Figure 26 As shown, when the first guide post 111 reaches C5, the second guide post 112 reaches B5, the guide post 21 reaches E5, A reaches A5, B reaches B5, and the air guide plate 1002 reaches the second open position; Figure 28 and Figure 31 As shown, the air deflector 1002 then moves toward the third open position, the first guide post 111 moves in the opposite direction (from C5 to C4) along the second mating section 314, i.e., C4C5, the second guide post 112 moves in the opposite direction (from D5 to D4) along the second mating section 314, i.e., D4D5, the guide post 21 moves along the fifth guide section 325, i.e., E5E6. When the first guide post 111 reaches C4, the second guide post 112 reaches D4, the guide post 21 reaches E6, A reaches A4, B reaches B6, and the air deflector 1002 reaches the third open position.

[0172] The drive device for the air deflector of the air conditioner includes a transmission member, which is drivably connected to a connecting rod, driving the connecting rod to move, thereby driving the air deflector 1002 to open and close. The movement of the transmission member can be rotational or other motion, such as sliding. When the movement of the transmission member is rotational, the rotating member 4 is the rotating member 4 described above.

[0173] The transmission member is provided with a first active part and a second active part, and the connecting rod is provided with a first driven part cooperating with the first active part and a second driven part cooperating with the second active part; during the opening process of the air guide plate 1002, the first active part first cooperates with the first driven part to drive the connecting rod to move, and then the second active part cooperates with the second driven part to drive the connecting rod to move.

[0174] In other words, during the opening process of the air guide plate 1002, the second active part and the second driven part do not fully cooperate, and the first active part and the first driven part fully cooperate or partially cooperate, which can reduce the size of one of the second active part and the second driven part.

[0175] The connecting rod can be the first connecting rod 1 or the second connecting rod 2. Figure 4 、 Figure 13 and Figure 24 As shown, when the connecting rod is the first connecting rod 1, one of the first active part and the first driven part includes a first transmission column 42, and the other includes a first transmission groove 12. When the first active part and the first driven part cooperate, the first transmission column 42 is arranged in the first transmission groove 12 and can slide relative to the first transmission groove 12; one of the second active part and the second driven part includes a second transmission column 43, and the other includes a second transmission groove 13. When the second active part and the second driven part cooperate, the second transmission column 43 is arranged in the second transmission groove 13 and can slide relative to the second transmission groove 13.

[0176] When the air deflector 1002 opens from the closed position to the first open position, the first transmission post 42 first engages with the first transmission slot 12, and the second transmission post 43 then engages with the second transmission slot 13. That is, during the opening process of the air deflector 1002, the first transmission post 42 is first located in the first transmission slot 12 and slides relative to the first transmission slot 12, and the second transmission post 43 then slides into the second transmission slot 13 and slides relative to the second transmission slot 13.

[0177] In other words, when the air guide plate 1002 starts to open from the closed position, the first transmission column 42 is first located in the first transmission groove 12 and can slide relative to the first transmission groove 12. At this time, the second transmission column 43 is not located in the second transmission groove 13. The force of the first transmission column 42 on the first transmission groove 12 drives the first connecting rod 1 to move. As the air guide plate 1002 moves further toward the first open position, the second transmission column 43 enters the second transmission groove 13 and can slide relative to the second transmission groove 13. At this time, the first connecting rod 1 mainly moves under the force of the second transmission column 43 on the second transmission groove 13. When the first transmission column 42 has not escaped from the first transmission groove 12, the driving force of the first transmission column 42 on the first transmission groove 12 plays an auxiliary role in the movement of the first connecting rod 1.

[0178] When the first transmission column 42 acts on the movement of the first connecting rod 1 and the second transmission column 43 does not act, the second transmission column 43 does not cooperate with the second transmission groove 13, thereby reducing the length of the second transmission groove 13; when the second transmission column 43 plays a major role in the movement of the first connecting rod 1, the first transmission column 42 plays an auxiliary role in the movement of the first connecting rod 1, thereby reducing the requirements for the shape of the first transmission groove 12, thereby increasing the design flexibility of the shape of the first transmission groove 12.

[0179] Optionally, the first transmission groove 12 and the second transmission groove 13 are both non-arc curved grooves, that is, the first transmission groove 12 and the second transmission groove 13 do not include arc groove segments, so that the motion trajectory of the first connecting rod 1 is not a straight line or an arc, but includes multiple trajectories (for example, the first sub-trajectory and the second sub-trajectory), and there is a deflection between two adjacent trajectories.

[0180] like Figure 17 As shown, when the first transmission groove 12 and the second transmission groove 13 are both provided on the first connecting rod 1, the first transmission groove 12 and the second transmission groove 13 are arranged in sequence along the length direction of the first connecting rod 1, which can reduce the width direction dimension of the first connecting rod 1.

[0181] Optionally, the first transmission groove 12 includes a first sub-transmission groove 121 and a second sub-transmission groove 122, the second sub-transmission groove 122 is connected to the first sub-transmission groove 121, and a first angle 123 is formed at the connection point; the first sub-transmission groove 121 and the second sub-transmission groove 122 are arranged in sequence along the length direction of the first connecting rod 1, and during the opening process of the air guide plate 1002, the first transmission column 42 cooperates with the first sub-transmission groove 121 and the second sub-transmission groove 122 in sequence.

[0182] During the opening of the air deflector 1002, the rotating member 4 rotates, but the rotation center O of the rotating member 4 remains unchanged, and the first connecting rod 1 moves approximately along the length of the first connecting rod 1. The first sub-transmission groove 121 and the second sub-transmission groove 122 are arranged in sequence along the length of the first connecting rod 1, so that the first transmission post 42 can first slide into the first sub-transmission groove 121 to engage with the first sub-transmission groove 121, and then slide into the second sub-transmission groove 122 to engage with the second sub-transmission groove 122.

[0183] Optionally, during the opening process of the air guide plate 1002 , the second transmission post 43 slides into the second transmission slot 13 before the first transmission post 42 slides relative to the first transmission slot 12 to the first folded angle 123 .

[0184] When the first transmission column 42 slides relative to the first transmission groove 12 to the first angle 123, the tangent direction of the first transmission groove 12 at the first angle 123 is nearly parallel to the movement direction of the first connecting rod 1. The driving force of the first transmission column 42 on the first transmission groove 12 is parallel to the tangent of the first angle 123 of the first transmission groove 12. The driving force of the first transmission column 42 on the first transmission groove 12 has a relatively small driving effect on the first connecting rod 1. Therefore, the second transmission column 43 is configured to slide into the second transmission groove 13 before the first transmission column 42 slides relative to the first transmission groove 12 to the first angle 123, so that before the driving force of the first transmission column 42 on the first transmission groove 12 has a relatively small driving effect on the first connecting rod 1, the second transmission column 43 has already played a driving role on the second transmission groove 13 to maintain the driving force on the first connecting rod 1.

[0185] Optionally, the second transmission groove 13 includes a third sub-transmission groove 131 and a fourth sub-transmission groove 132 . The fourth sub-transmission groove 132 is connected to the third sub-transmission groove 131 , and a second angle 133 is formed at the connection point.

[0186] The third sub-transmission groove 131 and the fourth sub-transmission groove 132 are sequentially arranged along the length direction of the first connecting rod 1 . When the air guide plate 1002 is opened, the second transmission column 43 cooperates with the third sub-transmission groove 131 and the fourth sub-transmission groove 132 in sequence.

[0187] The third sub-transmission groove 131 and the fourth sub-transmission groove 132 are arranged in sequence along the length direction of the first connecting rod 1, so that the second transmission column 43 can first slide into the third sub-transmission groove 131 and cooperate with the third sub-transmission groove 131, and then slide into the fourth sub-transmission groove 132 and cooperate with the fourth sub-transmission groove 132.

[0188] Optionally, the first transmission groove 12 is provided with an avoidance gap 124, such as Figure 17 As shown, the avoidance notch is provided at the starting end of the first sub-transmission groove 121. When the air deflector 1002 is opened, the first transmission post 42 enters the first sub-transmission groove 121 from the starting end. When the air deflector 1002 is opened, the second transmission post 43 passes through the avoidance notch and exits the second transmission groove 13. The first transmission groove 12 and the second transmission groove 13 have different depths. The first transmission post 42 fits in the first transmission groove 12, while the second transmission post 43 fits in the second transmission groove 13.

[0189] The depth of the first transmission groove 12 is greater than the depth of the second transmission groove 13, and the height of the first transmission column 42 is greater than the height of the second transmission column 43. Therefore, when the second transmission column 43 slides out through the avoidance gap, it will not drive the first transmission groove 12, thereby avoiding the cooperation between the second transmission column 43 and the first transmission groove 12 to affect the movement trajectory of the first connecting rod 1.

[0190] Optionally, the transmission member is further provided with a third active part, and the first connecting rod 1 is further provided with a third driven part cooperating with the third active part; during the opening process of the wind guide plate 1002, after the second active part cooperates with the second driven part, the third active part cooperates with the third driven part to drive the first connecting rod 1 to move.

[0191] One of the third active portion and the third driven portion includes a third transmission post 44, and the other includes a third transmission slot 14. During the opening process of the air deflector 1002, after the second transmission post 43 slides into and relative to the second transmission slot 13, the third transmission post 44 slides into and relative to the third transmission slot 14.

[0192] In the initial stage of the second transmission post 43 sliding into the second transmission slot 13, the third transmission post 44 has not yet entered the third transmission slot 14. Afterwards, the third transmission post 44 slides into the third transmission slot 14 and, together with the second transmission post 43, drives the first connecting rod 1 to move. This can increase the driving force on the first connecting rod 1. On the other hand, the second transmission post 43 and the third transmission post 44 drive the first connecting rod 1 in a relay manner, so that the third transmission slot 14 is not fully activated, thereby reducing the size of the third transmission slot 14.

[0193] Optionally, the third transmission groove 14 includes a fifth sub-transmission groove 141 and a sixth sub-transmission groove 142, the fifth sub-transmission groove 141 is connected to the sixth sub-transmission groove 142, and a third angle 143 is formed at the connection point; the fifth sub-transmission groove 141 and the sixth sub-transmission groove 142 are arranged in sequence along the width direction of the first connecting rod 1, and during the opening process of the air guide plate 1002, the third transmission column 44 cooperates with the fifth sub-transmission groove 141 and the sixth sub-transmission groove 142 in sequence.

[0194] Taking the example that the first transmission column 42, the second transmission column 43 and the third transmission column 44 are all arranged on the rotating part 4, changing the distance between the first transmission column 42, the second transmission column 43 and the third transmission column 44 and the rotation center of the rotating part 4 can change at least one of the shape, position and size of the first transmission groove 12, the second transmission groove 13 and the third transmission groove 14.

[0195] like Figure 16 As shown, the rotating member 4 is provided between the first connecting rod 1 and the second connecting rod 2. The rotating member 4 includes a rotating body 45 and a support arm 49 provided on the outer side of the rotating body 45. Figure 9 and Figure 10As shown, the rotating member 4 includes a first surface 41 and a second surface disposed opposite each other, with the first surface 41 facing the first connecting rod 1 and the second surface facing the second connecting rod 2. First to third transmission posts 44 are disposed on the first surface 41 and are each disposed on a support arm 49. The number of support arms 49 is multiple, and the multiple support arms 49 are sequentially disposed along the circumference of the rotating member 4. At least one transmission post (the transmission posts include a first transmission post 42, a second transmission post 43, and a third transmission post 44) is disposed on each support arm 49. The length of the support arm 49 where the first transmission column 42 is located is greater than the length of the support arm 49 where the second transmission column 43 is located, and the length of the support arm 49 where the second transmission column 43 is located is greater than the length of the support arm 49 where the third transmission column 44 is located, that is, the first transmission column 42, the second transmission column 43 and the third transmission column 44 are arranged in sequence along the circumference of the rotating member 4, the distance between the first transmission column 42 and the rotation center of the rotating member 4 is greater than the distance between the second transmission column 43 and the rotation center of the rotating member 4, the distance between the second transmission column 43 and the rotation center of the rotating member 4 is greater than the distance between the third transmission column 44 and the rotation center of the rotating member 4, and the distance between the first transmission column 42 and the second transmission column 43 is greater than the distance between the first transmission column 42 and the third transmission column 44.

[0196] Of course, the positions of the first transmission column 42, the second transmission column 43 and the third transmission column 44 can be adjusted, and the corresponding first transmission groove 12, the second transmission groove 13 and the third transmission groove 14 can also be adjusted, which can also enable the first connecting rod 1 to move along the predetermined trajectory.

[0197] Optionally, the third transmission groove 14 is a non-arc curved groove, that is, the third transmission groove 14 does not include an arc groove segment, and the fifth sub-transmission groove 141 and the sixth sub-transmission groove 142 are both non-arc curved grooves to satisfy that the motion trajectory of the first connecting rod 1 is not a straight line or a circular arc trajectory.

[0198] Optionally, when the first transmission groove 12, the second transmission groove 13, and the third transmission groove 14 are all provided in the first connecting rod 1, the first transmission groove 12, the second transmission groove 13, and the third transmission groove 14 are sequentially provided along the length direction of the first connecting rod 1 to reduce the width dimension of the first connecting rod 1. Specifically, the third transmission groove 14, the third sub-transmission groove 131, the fourth sub-transmission groove 132, the first sub-transmission groove 121, and the second sub-transmission groove 122 are sequentially provided along the length direction of the first connecting rod 1.

[0199] Among them, such as Figure 17 As shown, the first transmission groove 12, the second transmission groove 13 and the third transmission groove 14 are all arranged on the first connecting rod 1 or the rotating part 4, the first groove structure includes the first transmission groove 12, the second transmission groove 13 and the third transmission groove 14, the first column structure includes the first transmission column 42, the second transmission column 43 and the third transmission column 44, and the first sub-groove structure includes the first transmission groove 12 and the second transmission groove 13.

[0200] When the connecting rod is the second connecting rod 2, the first active part is the first boss 46 described below, the second active part is the second boss 47 described below, the first driven part is the first driving groove 22 described below, and the second driven part is the second driving groove 23 described below; or, when the connecting rod is the second connecting rod 2, the first active part is the first boss 46 described below, the second active part is the third boss 48 described below, the first driven part is the first driving groove 22 described below, and the second driven part is the third driving groove 24 described below.

[0201] like Figure 19 As shown, the second column structure includes a first boss 46, a second boss 47 and a third boss 48, and the second groove structure includes a first drive groove 22, a second drive groove 23 and a third drive groove 24. The first boss 46 cooperates with the first drive groove 22, the second boss 47 cooperates with the second drive groove 23, and the third boss 48 cooperates with the third drive groove 24. The third drive groove 24 is at least partially located in the space enclosed by the first drive groove 22 and the second drive groove 23. This can reduce the space occupied by the first drive groove 22, the second drive groove 23 and the third drive groove 24, so that the rotating member 4 or the second connecting rod 2 provided with the first drive groove 22, the second drive groove 23 and the third drive groove 24 is more compact.

[0202] Alternatively, as Figure 17 As shown, the first driving groove 22 , the second driving groove 23 and the third driving groove 24 are all non-arc-shaped curved grooves, that is, the first driving groove 22 , the second driving groove 23 and the third driving groove 24 are all curved grooves and do not have arc-shaped groove sections.

[0203] Optionally, the first driving groove 22 and the second driving groove 23 are arranged opposite to each other.

[0204] Optionally, the first drive groove 22 includes a first sub-drive groove 221 and a second sub-drive groove 222, the second sub-drive groove 222 is connected to the first sub-drive groove 221 and a fourth angle 223 is formed at the connection point, and during the opening process of the air guide plate 1002, the first protrusion 46 passes through the first sub-drive groove 221 and the second sub-drive groove 222 in sequence; wherein, the fourth angle 223 is less than 45°.

[0205] During the opening process of the air guide plate 1002, the first boss 46 first slides in the first sub-drive groove 221, and then slides into the second sub-drive groove 222 from the fourth bend 223. The fourth bend 223 is less than 45°, that is, the fourth bend 223 is small, and the sliding direction of the first boss 46 in the first sub-drive groove 221 relative to the first sub-drive groove 221 and the sliding direction of the first boss 46 in the second sub-drive groove 222 relative to the second sub-drive groove 222 are close, so that the first boss 46 can push the second connecting rod 2 to extend roughly along the length direction of the air duct 1003.

[0206] Optionally, the fourth fold angle 223 is less than or equal to 20°, for example, the fourth fold angle 223 is 5°, 10°, 15° or 20°.

[0207] An extension line of the end of the first sub-drive groove 221 facing away from the second sub-drive groove 222 intersects the second sub-drive groove 222. The center of curvature of the first sub-drive groove 221 is located on the side of the first sub-drive groove 221 facing the second sub-drive groove 222, so that the sliding direction of the first protrusion 46 in the first sub-drive groove 221 relative to the first sub-drive groove 221 and the sliding direction of the first protrusion 46 in the second sub-drive groove 222 relative to the second sub-drive groove 222 are close.

[0208] The first sub-driving groove 221 and the second sub-driving groove 222 are sequentially arranged along the length direction of the second connecting rod 2 so that when the first protrusion 46 cooperates with the first sub-driving groove 221 and the second sub-driving groove 222 , the predetermined trajectory of the second connecting rod 2 can be achieved.

[0209] The first sub-drive groove 221 is at least partially located in the space enclosed by the second sub-drive groove 222 and the second drive groove 23, and the third drive groove 24 is at least partially located in the space enclosed by the second sub-drive groove 222 and the second drive groove 23, so that the space occupied by the first drive groove 22, the second drive groove 23 and the third drive groove 24 is further reduced.

[0210] Optionally, the first driving slot 22 is provided with a first avoidance slot 224, through which the second boss 47 enters and exits the second driving slot 23. The first driving slot 22 is provided with a second avoidance slot 225, through which the third boss 48 enters and exits the third driving slot 24.

[0211] like Figure 6 As shown, when the air deflector 1002 is in the closed position, the first protrusion 46 is located in the first drive groove 22, and the second protrusion 47 and the third protrusion 48 are respectively located outside the second drive groove 23 and the third drive groove 24. The provision of the first avoidance groove and the second avoidance groove allows the second protrusion 47 to enter the second drive groove 23 through the first avoidance groove to cooperate with the second drive groove 23, and the third protrusion 48 to enter the third drive groove 24 through the second avoidance groove to cooperate with the third drive groove 24.

[0212] When the air guide plate 1002 is closed, the second protrusion 47 passes through the first avoidance groove and out of the second driving groove 23 , and the third protrusion 48 passes through the second avoidance groove and out of the third driving groove 24 .

[0213] Alternatively, as Figure 19 As shown, the second driving groove 23 includes a third sub-driving groove 231 and a fourth sub-driving groove 232 .

[0214] The third sub-drive groove 231 is connected to the fourth sub-drive groove 232. During the opening process of the air guide plate 1002, the second protrusion 47 cooperates with the third sub-drive groove 231 and the fourth sub-drive groove 232 in turn, and the connection point between the third sub-drive groove 231 and the fourth sub-drive groove 232 forms a fifth angle 233.

[0215] The third sub-driving groove 231 and the fourth sub-driving groove 232 are sequentially arranged along the length direction of the second connecting rod 2 , and the fifth angle 233 is close to 90° to meet the motion trajectory of the second connecting rod 2 .

[0216] The third sub-driving groove 231 extends substantially along the width direction of the second connecting rod 2 , and the fourth sub-driving groove 232 extends substantially along the length direction of the second connecting rod 2 .

[0217] Optionally, the second drive slot 23 further includes a fifth sub-drive slot 234. The fifth sub-drive slot 234 communicates with an end of the third sub-drive slot 231 facing away from the fourth sub-drive slot 232, and a sixth angle 235 is formed at the connection point. When the air deflector 1002 is opened, the second protrusion 47 sequentially engages with the fifth sub-drive slot 234 and the third sub-drive slot 231. The sixth angle 235 is an obtuse angle.

[0218] In the first open position, the second boss 47 is located at the sixth fold angle 235, which can improve the stability of the second boss 47 at this time and prevent the second boss 47 from sliding relative to the second drive groove 23, so that the air guide plate 1002 can be stably located in the first open position; in the second open position, the second boss 47 is located at the fifth fold angle 233, which can improve the stability of the second boss 47 at this time and prevent the second boss 47 from sliding relative to the second drive groove 23, so that the air guide plate 1002 can be stably located in the second open position.

[0219] Optionally, the third driving groove 24 includes a sixth sub-driving groove 242 and a seventh sub-driving groove 241 .

[0220] The sixth sub-drive groove 242 is connected to the seventh sub-drive groove 241, and the connection forms a seventh angle 243. During the opening of the air deflector 1002, the third protrusion 48 sequentially engages with the sixth and seventh sub-drive grooves 242 and 241. The seventh angle 243 is an acute angle and is greater than the fourth angle 223. The center of curvature of the seventh and sixth sub-drive grooves 241 and 242 is located on the same side of the seventh sub-drive groove 241, thereby satisfying the requirements for the motion trajectory of the second connecting rod 2.

[0221] Alternatively, as Figure 25 As shown, in the first open position, the third boss 48 is located at the seventh corner 243, which can improve the stability of the third boss 48 at this time and prevent the third boss 48 from sliding relative to the third driving groove 24, so that the air guide plate 1002 can be stably located in the first open position.

[0222] Optionally, the driving device for the air guide plate of the air conditioner includes a second connecting rod 2 and a transmission member. The movement form of the transmission member can be rotation or other movement, such as sliding. When the movement form of the transmission member is rotation, the rotating member 4 is the rotating member 4. The second connecting rod 2 is configured to be movably connected to the air guide plate 1002. The second connecting rod 2 is provided with a plurality of mating parts. The transmission member is provided with a plurality of driving parts, and the plurality of driving parts respectively cooperate with the plurality of mating parts. The movement of the transmission member drives the movement of the second connecting rod 2 to drive the air guide plate 1002 to open and close. At least two of the plurality of driving parts have different driving forces on the mating parts.

[0223] The driving portion cooperates with the matching portion to provide a driving force for the matching portion, thereby providing a driving force for the second connecting rod 2, so that the second connecting rod 2 can move according to a preset trajectory. The different driving forces can be different in magnitude. In this case, the at least two driving portions can share the driving force required for the second connecting rod 2, reducing the wear of the at least two driving portions. The different driving forces can also be different in direction. In this way, the angles between the driving forces in different directions and the movement direction of the second connecting rod 2 are different. The driving force with a smaller angle with the movement direction of the second connecting rod 2 is more effective. Therefore, the directions of the multiple driving forces are different, so that at least one driving force among the multiple driving forces is always in a more effective state, thereby ensuring the smooth movement of the second connecting rod 2.

[0224] Optionally, at least two of the multiple driving parts have different directions of driving force on the mating parts. Figure 25 In the embodiment, the directions of the driving forces F1, F2 and F3 of the three driving parts on the matching parts are all different.

[0225] The motion trajectory of each point on the second connecting rod 2 is the same. Therefore, the angles between the driving forces in different directions and the motion direction of the second connecting rod 2 are different. The different angles result in different efficiencies in converting the driving force into the driving force on the second connecting rod 2, that is, different effectiveness of the driving force. When the angle is small, the effectiveness is high; when the angle is large, the effectiveness is low. The motion direction of the second connecting rod 2 is not constant. Therefore, the angle between the driving force and the motion direction of the second connecting rod 2 refers to the angle between the driving force and the motion direction of the second connecting rod 2 at the same moment.

[0226] At least two of the multiple driving parts are provided with different directions of driving forces on the matching parts. In this way, at least one of the driving forces can be selected to have a smaller angle with the movement direction of the second connecting rod 2, which plays a major driving role in the movement of the second connecting rod 2. This allows the position, shape and other parameters of the driving part and the matching part to be flexibly set, thereby optimizing the driving device for the air guide plate of the air conditioner.

[0227] Optionally, the angle between the driving force of the mating part of at least one driving part and the movement direction of the second connecting rod 2 is less than or equal to 20°, such as 0°, 5°, 10°, 15° or 20°. Figure 25 The included angle between the intermediate driving force F3 and the moving direction of the second connecting rod 2 is less than or equal to 20°.

[0228] In this way, the angle between the driving force of the at least one driving part and the moving direction of the second connecting rod 2 is small, and the effectiveness of the driving force is high, thereby ensuring that the second connecting rod 2 can move smoothly.

[0229] When the air deflector 1002 is in different positions, the direction of the driving force of the same driving unit may change. Therefore, in the statement "the angle between the driving force of the mating unit of at least one driving unit and the direction of movement of the second connecting rod 2 is less than or equal to 20 degrees", when the air deflector 1002 is in different positions, at least one driving unit may be a different driving unit. For example, when the air deflector 1002 is in the first open position, the angle between the driving force of the mating unit of the first driving unit and the direction of movement of the second connecting rod 2 is less than or equal to 20 degrees. When the air deflector 1002 is in the second open position, the angle between the driving force of the mating unit of the second driving unit and the direction of movement of the second connecting rod 2 is less than or equal to 20 degrees. The driving unit includes a first driving unit and a second driving unit.

[0230] Optionally, the transmission member rotates in a controlled manner, and at least two of the multiple driving parts are arranged in sequence along the circumference of the transmission member.

[0231] This arrangement enables the driving forces of the mating parts of the multiple driving parts arranged in sequence along the circumference of the transmission member to be in different directions and at different positions, that is, the driving forces act on different positions of the second connecting rod 2, thereby jointly promoting the smooth movement of various parts of the second connecting rod 2.

[0232] Optionally, the transmission member rotates in a controlled manner, and at least two of the multiple driving parts are at unequal distances from the rotation center of the transmission member. This arrangement causes the multiple matching parts to not overlap.

[0233] like Figure 10 As shown, the driving part is provided on the second surface 451 of the rotating part 4, and the multiple driving parts are staggered with the first transmission column 42, the second transmission column 43 and the second transmission column 43 provided on the first surface 41, so that the positions of the driving forces of the rotating part 4 on the first connecting rod 1 and the second connecting rod 2 are different, that is, the driving force is applied to the first connecting rod 1 and the second connecting rod 2 at different positions of the rotating part 4, thereby avoiding excessive local force on the rotating part 4.

[0234] like Figure 9 and Figure 10As shown, the driving part is provided on the support arm 49 , and the driving part may be located on the same support arm 49 as the first transmission column 42 , the second transmission column 43 and the second transmission column 43 , or may not be located on the same support arm 49 .

[0235] Optionally, one of the matching portion and the driving portion is a driving groove, and the other is a convex column, which is located in the driving groove and can slide relative to the driving groove to provide a driving force for the movement of the second connecting rod 2.

[0236] Optionally, the driving groove includes a first driving groove 22, a second driving groove 23 and a third driving groove 24, and the boss includes a first boss 46 corresponding to the first driving groove 22, a second boss 47 corresponding to the second driving groove 23 and a third boss 48 corresponding to the third driving groove 24; wherein the directions of the driving force between the first boss 46 and the first driving groove 22, the driving force between the second boss 47 and the second driving groove 23, and the driving force between the third boss 48 and the third driving groove 24 are different.

[0237] In this way, at different positions of the air guide plate 1002, at least one of the driving force between the first boss 46 and the first driving groove 22, the driving force between the second boss 47 and the second driving groove 23, and the driving force between the third boss 48 and the third driving groove 24 can be set with higher effectiveness, thereby ensuring the reliability of the movement of the second connecting rod 2.

[0238] The driving force between the Nth boss and the Nth driving groove refers to the driving force between the Nth boss and the Nth driving groove if the driving portion includes the Nth boss, and the driving force between the Nth boss and the Nth driving groove if the driving portion includes the Nth driving groove. N = 1, 2, or 3.

[0239] like Figure 10 As shown, the first boss 46, the second boss 47 and the third boss 48 are arranged in sequence along the circumference of the rotating member 4, and the distances between the first boss 46, the second boss 47 and the third boss 48 and the rotation center of the rotating member 4 are not equal, so that the driving force between the first boss 46 and the first driving groove 22, the driving force between the second boss 47 and the second driving groove 23, and the driving force between the third boss 48 and the third driving groove 24 act on different positions of the second connecting rod 2.

[0240] like Figure 10 As shown, the first boss 46, the second boss 47 and the third boss 48 are all arranged on the second surface 451, and the distance between the first boss 46 and the rotation center of the rotating member 4 is greater than the distance between the second boss 47 and the rotation center of the rotating member 4, and is also greater than the distance between the third boss 48 and the rotation center of the rotating member 4.

[0241] Optionally, during the opening process of the air guide plate 1002, the first boss 46 is located in the first drive groove 22 throughout and can slide relative to the first drive groove 22, the second boss 47 and the second drive groove 23 have a matching stage and a separation stage, and the third boss 48 and the third drive groove 24 have a matching stage and a separation stage.

[0242] When the air guide plate 1002 starts to open from the closed position, the first boss 46 is located in the first drive groove 22 and can slide relative to the first drive groove 22. The second boss 47 has not slid into the second drive groove 23, and the third boss 48 has not slid into the third drive groove 24. At this time, the driving force of the first boss 46 on the first drive groove 22 serves as the driving force for the movement of the second connecting rod 2. Before the air guide plate 1002 opens to the first open position, the second boss 47 slides into the second drive groove 23 and slides relative to the second drive groove 23. The third boss 48 slides into the third drive groove 24 and slides relative to the third drive groove 24. The driving force of the first boss 46 on the first drive groove 22, the driving force of the second boss 47 on the second drive groove 23, and the driving force of the third boss 48 on the third drive groove 24 jointly drive the movement of the second connecting rod 2.

[0243] The drive device for the air deflector of an air conditioner includes a second connecting rod 2, a transmission member, a first column and a first power slot 2221, a second column, and a second power slot. The second connecting rod 2 is configured to be movably connected to the air deflector 1002; the transmission member is drivingly connected to the second connecting rod 2, driving the second connecting rod 2 to move, thereby driving the air deflector 1002 to open and close. The first column and the first power slot 2221 are respectively located on the second connecting rod 2 and the transmission member; the second column and the second power slot are respectively located on the second connecting rod 2 and the transmission member.

[0244] During the process of the air guide plate 1002 opening from the first preset position to the second preset position, the first column or the first power groove 2221 provided on the transmission member slides relative to the first column or the first power groove 2221 provided on the second connecting rod 2 toward the direction of retracting the air duct 1003, and the second column or the second power groove provided on the transmission member slides relative to the second column or the second power groove provided on the second connecting rod 2 toward the direction of extending the air duct 1003, wherein the air guide plate 1002 passes through the first preset position and the second preset position in sequence during the opening process.

[0245] like Figure 10 and Figure 32As shown, when the first column is provided on the transmission member and the first power groove 2221 is provided on the second connecting rod 2, “the first column or the first power groove 2221 provided on the transmission member slides relative to the first column or the first power groove 2221 provided on the second connecting rod 2 toward the direction of retracting the air duct 1003” means that the first column slides relative to the first power groove 2221 toward the direction of retracting the air duct 1003. When the first column is provided on the second connecting rod 2 and the first power groove 2221 is provided on the transmission member, “the first column or the first power groove 2221 provided on the transmission member slides relative to the first column or the first power groove 2221 provided on the second connecting rod 2 toward the direction of retracting the air duct 1003” means that the first power groove 2221 slides relative to the first column toward the direction of retracting the air duct 1003.

[0246] When the second column is provided on the transmission member and the second power trough is provided on the second connecting rod 2, “the second column or the second power trough provided on the transmission member slides relative to the second column or the second power trough provided on the second connecting rod 2 toward the direction of extending out of the air duct 1003” means that the second column slides relative to the second power trough toward the direction of extending out of the air duct 1003. When the second column is provided on the second connecting rod 2 and the second power trough is provided on the transmission member, “the second column or the second power trough provided on the transmission member slides relative to the second column or the second power trough provided on the second connecting rod 2 toward the direction of extending out of the air duct 1003” means that the second power trough slides relative to the second column toward the direction of extending out of the air duct 1003.

[0247] like Figure 25 、 Figure 30 and Figure 32 As shown, in the process of the air guide plate 1002 opening from the first preset position to the second preset position, the first column or the first power groove 2221 provided on the transmission member slides relative to the first column or the first power groove 2221 provided on the second connecting rod 2 toward the direction of retracting the air duct 1003, and the second column or the second power groove provided on the transmission member slides relative to the second column or the second power groove provided on the second connecting rod 2 toward the direction of extending the air duct 1003, which can reduce the stroke of the second connecting rod 2 extending toward the direction of extending the air duct 1003 or can drive the second connecting rod 2 to retract into the air duct 1003, thereby reducing the space occupied by the second connecting rod 2 and reducing the space occupied by the driving device for the air guide plate of the air conditioner.

[0248] The first preset position is the maximum air supply position, that is, the second open position, and the second preset position is the third open position.

[0249] As the air guide plate 1002 continues to move from the second open position to the third open position, the second connecting rod 2 moves in a direction of retraction into the air duct 1003, meeting the position requirements of the air guide plate 1002 in the second open position and the third open position.

[0250] The motion form of the transmission member can be rotation, or other motions, such as sliding. When the motion form of the transmission member is rotation, the rotating member 4 is the above-mentioned rotating member 4.

[0251] Alternatively, as Figure 25 As shown, the first power groove 2221 extends generally along the length direction of the second connecting rod 2. The first power groove 2221 is a non-circular curved groove, that is, the first power groove 2221 does not include a circular groove segment. The second power groove extends generally along the length direction of the second connecting rod 2. The second power groove is a non-circular curved groove, that is, the second power groove does not include a circular groove segment.

[0252] When the first column is located in the first power groove 2221 and slides relative to the first power groove 2221 , and the second column is located in the second power groove and slides relative to the second power groove, the trajectory requirements for the second connecting rod 2 can be met.

[0253] Optionally, the transmission member rotates in a controlled manner, and the distance between the first column and the rotation center of the transmission member is unequal to the distance between the second column and the rotation center of the transmission member, so that the first power slot 2221 and the second power slot do not overlap.

[0254] The first column and the second column are sequentially arranged along the circumference of the rotating member 4 , so that the driving forces generated by the first column and the second column on the second connecting rod 2 are in different directions, and the combined force of the driving forces in different directions jointly drives the second connecting rod 2 to move smoothly.

[0255] Alternatively, as Figure 25 As shown, the driving device for the air-conditioning air guide plate also includes a third column and a third power groove 2412, one of the third column and the third power groove 2412 is provided on the second connecting rod 2, and the other is provided on the transmission member; the third column or the third power groove 2412 provided on the transmission member slides relative to the third column or the third power groove 2412 provided on the second connecting rod 2 toward the direction of extending out of the air duct 1003.

[0256] When the third column is provided on the transmission member and the third power groove 2412 is provided on the second connecting rod 2, “the third column or the third power groove 2412 provided on the transmission member slides relative to the third column or the third power groove 2412 provided on the second connecting rod 2 toward the direction of extending out of the air duct 1003” means that the third column slides relative to the third power groove 2412 toward the direction of extending out of the air duct 1003. When the third column is provided on the second connecting rod 2 and the third power groove 2412 is provided on the transmission member, “the third column or the third power groove 2412 provided on the transmission member slides relative to the third column or the third power groove 2412 provided on the second connecting rod 2 toward the direction of extending out of the air duct 1003” means that the third power groove 2412 slides relative to the third column toward the direction of extending out of the air duct 1003.

[0257] The driving force provided to the second connecting rod 2 by the cooperation between the second column and the second power slot, and the cooperation between the third column and the third power slot 2412, is in the direction of extending the air duct 1003. The driving force provided to the second connecting rod 2 by the cooperation between the first column and the first power slot 2221 is in the direction of retracting the air duct 1003. During the entire process of the air deflector 1002 opening from the first preset position to the second open position, the displacement of the second connecting rod 2 is in the direction of retracting the air duct 1003. Therefore, during the entire process of the air deflector 1002 opening from the first preset position to the second open position, the effectiveness of the driving force provided to the second connecting rod 2 by the cooperation between the first column and the first power slot 2221 is greater than the effectiveness of the driving force provided to the second connecting rod 2 by the cooperation between the second column and the second power slot, and the cooperation between the third column and the third power slot 2412.

[0258] Optionally, the third power groove 2412 extends along the length direction of the second connecting rod 2 , and the third power groove 2412 is a non-circular curved groove to meet the requirements for the motion trajectory of the second connecting rod 2 .

[0259] Optionally, when the first power groove 2221, the second power groove and the third power groove 2412 are all provided in the second connecting rod 2 or the transmission member, the third power groove 2412 is provided between the first power groove 2221 and the second power groove, so that the structure of the second connecting rod 2 or the transmission member provided with the first power groove 2221, the second power groove and the third power groove 2412 is compact and small in size.

[0260] Alternatively, as Figure 32 As shown, when the first power groove 2221, the second power groove, and the third power groove 2412 are all provided in the second connecting rod 2 or the transmission member, the extension line of the third power groove 2412 intersects with the extension line of the first power groove 2221, and the extension line of the third power groove 2412 intersects with the extension line of the second power groove. The center of curvature of the first power groove 2221 is located on the side of the first power groove 2221 facing the third power groove 2412, the center of curvature of the second power groove is located on the side of the second power groove facing the third power groove 2412, and the center of curvature of the third power groove 2412 is located on the side of the third power groove 2412 facing the first power groove 2221.

[0261] The setting position of the center of curvature of the first power groove 2221, the second power groove and the third power groove 2412 affects the bending direction of the first power groove 2221, the second power groove and the third power groove 2412, thereby affecting the direction of the driving force of the second connecting rod 2 caused by the cooperation between the first boss 46 and the first power groove 2221, the cooperation between the second boss 47 and the second power groove, and the cooperation between the third boss 48 and the third power groove 2412, thereby affecting the movement direction of the second connecting rod 2.

[0262] As the air guide plate 1002 continues to open from the first preset position to the second preset position, the second connecting rod 2 has a sub-movement of retracting into the air duct 1003, and also has a sub-movement of moving upward (when the second preset position is the heating downward blowing position) or downward (when the second preset position is the cooling horizontal blowing position). The positions of the centers of curvature of the first power groove 2221, the second power groove, and the third power groove 2412 enable the second connecting rod 2 to have not only a sub-movement of retracting into the air duct 1003, but also a sub-movement of moving upward or downward.

[0263] The first column is the first protrusion 46, the second column is the second protrusion 47, and the third column is the third protrusion 48. The first power slot 2221, the second power slot, and the third power slot 2412 are slots that mate with the first protrusion 46, the second protrusion 47, and the third protrusion 48, respectively, when the air deflector 1002 moves from the second open position to the third open position. Therefore, the second sub-drive slot 222 includes the first power slot 2221, the second power slot is the fourth sub-drive slot 232, and the seventh sub-drive slot 241 includes the third power slot 2412.

[0264] like Figure 32 As shown, the second sub-drive slot 222 further includes a fourth power slot 2222, which is connected to the first power slot 2221. The center of curvature of the fourth power slot 2222 is located on the side of the fourth power slot 2222 facing the first sub-drive slot 221. When the air deflector 1002 moves from the first open position to the second open position, the first protrusion 46 engages with the fourth power slot 2222.

[0265] The seventh sub-drive slot 241 further includes a fifth drive slot 2411, which is connected to the third drive slot 2412, forming an eighth angle 2413 at the connection point. When the air deflector 1002 moves from the first open position to the second open position, the third protrusion 48 engages with the fifth drive slot 2411.

[0266] like Figure 4 and Figure 6 As shown, the air guide plate 1002 is in the closed position, the first transmission column 42 is located at the starting end of the first transmission groove 12, the second transmission column 43 and the third transmission column 44 are located outside the second transmission groove 13 and the third transmission groove 14 respectively, the first protrusion 46 is located in the first sub-drive groove 221, and the second protrusion 47 and the third protrusion 48 are located outside the second drive groove 23 and the third drive groove 24 respectively. Figure 13 and Figure 15As shown, when the air deflector 1002 moves from the closed position toward the first open position, the first transmission post 42 is located in the first sub-transmission groove 121 and moves relative to the first sub-transmission groove 121. After the first transmission post 42 starts to slide relative to the first sub-transmission groove 121, the second transmission post 43 enters the third sub-transmission groove 131 and slides relative to the third sub-transmission groove 131. The first protrusion 46 slides relative to the first sub-drive groove 221, the second protrusion 47 slides into the fifth sub-drive groove 234, and the third protrusion 48 slides into the sixth sub-drive groove 242. Figure 13 and Figure 15 As shown, when the air guide plate 1002 reaches the first open position, the first transmission post 42 is located near the first folded corner 123, the second transmission post 43 is located near the second folded corner 133, the first protrusion 46 is located near the fourth folded corner 223, the second protrusion 47 is located near the sixth folded corner 235, and the third protrusion 48 is located near the seventh folded corner 243; Figure 24 and Figure 25 As shown, when the air guide plate 1002 continues to move toward the second open position, the first transmission post 42 cooperates with the second sub-transmission groove 122, the second transmission post 43 cooperates with the fourth sub-transmission groove 132, and the third transmission post 44 slides into the fifth sub-transmission groove 141, so that the third transmission post 44 cooperates with the fifth sub-transmission groove 141. Thereafter, the cooperation between the third transmission post 44 and the third transmission groove 14 plays a major driving role in the movement of the first connecting rod 1, and the cooperation between the second transmission post 43 and the second transmission groove 13, and the cooperation between the first transmission post 42 and the first transmission groove 12 both play an auxiliary role. The first protrusion 46 cooperates with the fourth power groove 2222, the second protrusion 47 cooperates with the third sub-drive groove 231, and the third protrusion 48 cooperates with the fifth power groove 2411; before the air guide plate 1002 reaches the second open position, the first transmission post 42 passes through the second sub-transmission groove 122; as shown Figure 24 and Figure 25 As shown, when the air deflector 1002 reaches the second open position, the second transmission column 43 is located in the fourth sub-transmission groove 132, the third transmission column 44 is located near the third folded corner 143, the first protrusion 46 is located at the connection between the fourth power groove 2222 and the first power groove 2221, the second protrusion 47 is located near the fifth folded corner 233, and the third protrusion 48 is located near the eighth folded corner 2413; when the air deflector 1002 moves toward the third open position, as shown in FIG. Figure 29 and Figure 30 As shown, the second transmission column 43 first cooperates with the second transmission groove 13, and then disengages from the second transmission groove 13. The third transmission column 44 moves along the sixth sub-transmission groove 142. The third transmission column 44 plays a major role in driving the movement of the first connecting rod 1. The first boss 46 cooperates with the first power groove 2221, the second boss 47 cooperates with the fourth sub-drive groove 232, and the third boss 48 cooperates with the third power groove 2412.
