[0063] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0064] Combination Figure 1-26 As shown, this embodiment of the present disclosure provides a driving device for an air conditioning air guide plate 30, including a drive wheel 301, a first rack 101 and a connecting rod 20.

[0065] The drive wheel 301 rotates under control and includes a first toothed portion 206 and a drive portion; the first rack 101 meshes with the first toothed portion 206 and is directly rotatably connected to the air guide plate 30 through the first rotating shaft 102; the connecting rod 20 cooperates with the drive portion and is drivenly connected to the air guide plate 30.

[0066] The drive wheel 301 rotates, which drives the first rack 101 and the connecting rod 20 to move through the first tooth 206 and the drive part, respectively, so as to open and close the air guide plate 30.

[0067] During the opening of the air guide plate 30, the movement trajectory of the first rack 101 is a straight line or an arc, so that the connecting rod 20 drives the air guide plate 30 to rotate around the first rotating shaft 102.

[0068] During the opening of the air guide plate 30, the movement trajectory of the first rack 101 is a straight line or an arc. The drive unit cooperates with the connecting rod 20 to drive the connecting rod 20 to move. The movement of the connecting rod 20 can drive the air guide plate 30 to rotate around the first rotating shaft 102, thereby realizing the cooling and heating modes of the air conditioner.

[0069] Example 1:

[0070] like Figures 1 to 13 As shown, the drive unit includes a second toothed portion 207, and the connecting rod 20 includes a second rack 201 that meshes with the second toothed portion 207.

[0071] The drive wheel 301 rotates under control and includes a first toothed portion 206 and a second toothed portion 207. The first rack 101 meshes with the first toothed portion 206 and is directly rotatably connected to the air guide plate 30 through a first rotating shaft 102. For example, the first rack 101 has a first shaft hole 501, and the first rotating shaft 102 is fixedly mounted on the air guide plate 30, passing through the first shaft hole 501 and rotatably connected to it. The second rack 201 meshes with the second toothed portion 207 and is directly rotatably connected to the air guide plate 30 through a second rotating shaft 202. For example, the second rack 201 has a second shaft hole 502, and the second rotating shaft 202 is fixedly mounted on the air guide plate 30, passing through the second shaft hole 502 and rotatably connected to it. The drive wheel 301 rotates, driving the first rack 101 and the second rack 201 to move, thereby driving the air guide plate 30 to open and close.

[0072] During the opening of the air guide plate 30, the movement trajectory of the first rack 101 is a straight line or an arc, so that the second rack 201 drives the air guide plate 30 to rotate around the first rotating shaft 102.

[0073] The first rack 101 is a one-piece structure, directly rotatably connected to the air guide plate 30 via the first rotating shaft 102. No other connecting rods 603 connect the first rack 101 to the air guide plate 30. Similarly, the second rack 201 is a one-piece structure, directly rotatably connected to the air guide plate 30 via the second rotating shaft 202. No other connecting rods 603 connect the second rack 201 to the air guide plate 30. Furthermore, both the first rack 101 and the second rack 201 are rotatably connected to the air guide plate 30, rather than slidingly connected, thus avoiding wear on the first rack 101 and the second rack 201 during sliding.

[0074] In this application, during the opening of the air guide plate 30, the movement trajectory of the first rack 101 is a straight line or an arc. The meshing of the second tooth 207 with the second rack 201 drives the second rack 201 to move. The movement of the second rack 201 can drive the air guide plate 30 to rotate around the first rotating shaft 102, thereby realizing the cooling and heating modes of the air conditioner.

[0075] In other words, by limiting the movement trajectory of the first rack 101, the second rack 201 can drive the air guide plate 30 to rotate around the first rotating shaft 102, thereby realizing the up and down air guidance of the air guide plate 30, that is, realizing the cooling and heating mode of the air conditioner, without the need to set up a connecting rod 603 or a sliding connection, which simplifies the structure of the driving device for the air conditioner air guide plate 30. It also eliminates the need for controlling the first transmission tooth and the transmission gear, and the second transmission tooth and the transmission gear to not mesh simultaneously, which also simplifies the structure of the driving device for the air conditioner air guide plate 30.

[0076] Optionally, the first rack 101 includes a straight segment or an arc segment, and the gear teeth that mesh with the first tooth portion 206 are located on the straight segment or the arc segment. For example... Figures 4 to 6 , Figure 8 , Figure 11 and Figure 13 As shown, the first rack 101 includes a straight segment.

[0077] The first rack 101 includes a straight segment or an arc segment, the shape of which is precisely matched to the movement trajectory (straight or arc) of the first rack 101. This design ensures that the first rack 101 can move smoothly along a predetermined trajectory (straight or arc) when meshing with the first tooth 206, avoiding movement deviations or jamming caused by shape mismatch. For example, when the movement trajectory of the first rack 101 is a straight line, the design of the straight segment ensures that it (the first rack 101) maintains stable straight movement during the movement; when the movement trajectory is an arc, the design of the arc segment allows it (the first rack 101) to move smoothly along the arc trajectory, thereby achieving precise control of the air guide plate 30.

[0078] The first rack 101 may not include a straight section or a circular arc section. Instead, the first rack 101 may include a non-circular arc curved section, and the gear teeth that mesh with the first tooth 206 are located on the curved section. In this case, the first tooth 206 may be a non-circular gear.

[0079] Optionally, during the opening of the air guide plate 30, the movement trajectory of the second rack 201 is a variable trajectory line, that is, neither a straight line nor a circular arc.

[0080] During the opening of the air guide plate 30, the movement trajectory of the second rack 201 is neither linear nor circular. This unconventional movement trajectory design allows the second rack 201 to rotate around the first rotating shaft 102 when it meshes with the second tooth 207. This enables the air guide plate 30 to achieve more complex and diverse movement patterns during the opening process, thereby better meeting the special requirements of the air conditioner for the movement trajectory of the air guide plate 30 under different operating modes, and further improving the air guiding effect and comfort of the air conditioner.

[0081] Optionally, during the opening of the air guide plate 30, the movement trajectory of the second rack 201 includes a first trajectory segment and a second trajectory segment connected in sequence; along the extension direction of the second rack 201 during the opening of the air guide plate 30, the extension directions of the first trajectory segment and the second trajectory segment are opposite.

[0082] Along the direction of movement of the second rack 201 during the opening of the air guide plate 30, the first trajectory segment and the second trajectory segment are arranged sequentially. Along the extension direction of the second rack 201, the extension directions of the first trajectory segment and the second trajectory segment are opposite. For example, the first trajectory segment is inclined upward and the second trajectory segment is inclined downward, or the first trajectory segment is inclined downward and the second trajectory segment is inclined upward.

[0083] As the air guide plate 30 opens, the extension direction of the second rack 201 (which is roughly the same as the length direction of the second rack 201) is opposite to the extension direction of the first and second trajectory segments. This allows the second rack 201 to quickly change its direction of movement during the movement, thereby driving the air guide plate 30 to quickly adjust the air guide angle, achieving rapid switching of the air outlet direction, realizing cooling and heating modes, improving the air conditioner's response speed and adjustment efficiency, and meeting users' needs for rapid switching of the air conditioner's air outlet direction in different scenarios.

[0084] Optionally, both the first trajectory segment and the second trajectory segment are curves, and the curvature centers of the first trajectory segment and the second trajectory segment are located on opposite sides of the motion trajectory of the second rack 201.

[0085] The curvature center of the first trajectory segment is located below the motion trajectory of the second rack 201, and the curvature center of the second trajectory segment is located above the motion trajectory of the second rack 201. That is, the bending direction of the first trajectory segment is different from that of the second trajectory segment. When the second rack 201 moves along the first trajectory segment, the second rack 201 pushes the air guide plate 30 to rotate around the first rotating shaft 102, so that the air guide plate 30 rotates downward. When the second rack 201 moves along the second trajectory segment, the second rack 201 pushes the air guide plate 30 to rotate around the first rotating shaft 102, so that the air guide plate 30 rotates upward.

[0086] Alternatively, the curvature center of the first trajectory segment may be located above the motion trajectory of the second rack 201, and the curvature center of the second trajectory segment may be located below the motion trajectory of the second rack 201. That is, the bending direction of the first trajectory segment and the bending direction of the second trajectory segment are different. When the second rack 201 moves along the first trajectory segment, the second rack 201 pushes the air guide plate 30 to rotate around the first rotating shaft 102, causing the air guide plate 30 to rotate upward. When the second rack 201 moves along the second trajectory segment, the second rack 201 pushes the air guide plate 30 to rotate around the first rotating shaft 102, causing the air guide plate 30 to rotate downward.

[0087] When both the first and second trajectory segments are circular arcs, the curvature center is the center of the circle in the statement "the curvature center of the first trajectory segment and the curvature center of the second trajectory segment are located on opposite sides of the motion trajectory of the second rack 201".

[0088] Optionally, the first trajectory segment is a straight line or an arc, and the second trajectory segment is a straight line or an arc.

[0089] When the first trajectory segment is a straight line, the second trajectory segment can be either a straight line or an arc. When the first trajectory segment is an arc, the second trajectory segment can be either a straight line or an arc.

[0090] A straight or arc shape can simplify the shape of the second rack 201 and the second tooth 207, thereby simplifying the drive mechanism for the air conditioning guide vane 30.

[0091] When both the first and second trajectory segments are straight lines, they are not collinear. When both the first and second trajectory segments are arcs, they are not located on the same circumference. This allows the second rack 201 to quickly change its direction of motion during movement, thereby driving the air guide plate 30 to quickly adjust its air guide angle, achieving rapid switching of the air outlet direction, realizing cooling and heating modes, improving the air conditioner's response speed and adjustment efficiency, and meeting users' needs for rapid switching of the air conditioner's air outlet direction in different scenarios.

[0092] Optionally, such as Figure 12 As shown, the second rack 201 includes a recess 203 and a protrusion 204 arranged sequentially along the length direction of the second rack 201. Both the recess 203 and the protrusion 204 are provided with gear teeth that mesh with the second tooth 207.

[0093] During the movement of the air guide plate 30, the second rack 201 needs to move along a non-linear, non-circular trajectory. The structure of the concave part 203 and the convex part 204 can meet the requirements of the movement trajectory of the second rack 201.

[0094] The second rack 201 includes a recess 203 and a plurality of protrusions 204. The recess 203 is one in number and is located between the plurality of protrusions 204, such as... Figure 12 As shown, there are two protrusions 204, and the concave part 203 is located between the two protrusions 204.

[0095] Alternatively, the second rack 201 may include a plurality of recesses 203 and protrusions 204, wherein there is one protrusion 204 located between the plurality of recesses 203, and there are two recesses 203, wherein the protrusion 204 is located between the two recesses 203.

[0096] The recess 203 and the protrusion 204 are provided on the surface of the second rack 201 facing the second tooth 207.

[0097] Optionally, such as Figure 8 As shown, both the first tooth 206 and the second tooth 207 are cylindrical gears, and the axes of the first tooth 206 and the second tooth 207 coincide.

[0098] like Figure 14 As shown, the driving device for the air conditioning guide plate 30 also includes a motor 10. The motor 10 is driven to the first tooth 206 or the second tooth 207. The first tooth 206 and the second tooth 207 are fixedly connected to drive the first tooth 206 and the second tooth 207 to rotate. In this way, only one motor 10 is needed to drive the first rack 101 and the second rack 201 to move simultaneously.

[0099] The first tooth 206 and the second tooth 207 have the same angular velocity, and the radii of the first tooth 206 and the second tooth 207 can be the same or different.

[0100] Optionally, such as Figures 1 to 8 As shown, the driving device for the air conditioning guide plate 30 also includes a mechanism box 40, in which the first rack 101 and the second rack 201, the first tooth 206 and the second tooth 207 are all disposed inside the mechanism box 40 and move between the position of extending out of the mechanism box 40 and the position of retracting into the mechanism box 40.

[0101] like Figure 2 and Figure 5 As shown, the first rack 101 is provided with a first guide part 103, and the mechanism box 40 is provided with a first guide mating part 401. During the movement of the first rack 101, the first guide part 103 and the first guide mating part 401 cooperate to guide the movement trajectory of the first rack 101, so that the first rack 101 always moves along the predetermined trajectory, thereby improving the guiding accuracy of the movement of the first rack 101 and ensuring the accuracy and stability of the movement of the air guide plate 30.

[0102] One of the first guide portion 103 and the first guide mating portion 401 is a first guide groove, and the other is a first guide post. The first guide post is located in the first guide groove and can slide along the length direction of the first guide groove.

[0103] like Figure 5 As shown, the first guide groove is provided on the surface of the first rack 101 away from the second rack 201, and the mechanism box 40 is provided with a first guide post. The first guide groove is straight or arc-shaped, and the shape of the first guide groove is the same as the movement trajectory of the first rack 101.

[0104] The number of first guide parts 103 is one or more, and the number of first guide mating parts 401 is equal to the number of first guide parts 103 and corresponds one-to-one.

[0105] like Figure 3 and Figure 12 As shown, the second rack 201 is provided with a second guide part 205, and the mechanism box 40 is provided with a second guide mating part 402. During the movement of the second rack 201, the second guide part 205 and the second guide mating part 402 cooperate to guide the movement trajectory of the second rack 201, so that the second rack 201 always moves along the predetermined trajectory, thereby improving the guiding accuracy of the movement of the second rack 201 and ensuring the accuracy and stability of the movement of the air guide plate 30.

[0106] One of the second guide portion 205 and the second guide mating portion 402 is a second guide groove, and the other is a second guide post. The second guide post is located in the second guide groove and can slide along the length direction of the second guide groove.

[0107] like Figure 3 As shown, the second guide groove includes a first sub-guide groove segment 405 and a second sub-guide groove segment 406 that are connected. During the opening of the air guide plate 30, the second guide column slides through the first sub-guide groove segment 405 and the second sub-guide groove segment 406 in sequence.

[0108] During the opening of the air guide plate 30, the extension direction of the second rack 201 is opposite to that of the first sub-guide groove section 405 and the second sub-guide groove section 406.

[0109] Along the direction of movement of the second rack 201 during the opening of the air guide plate 30, the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are sequentially arranged. Along the extension direction of the second rack 201, the extension directions of the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are opposite; for example, Figure 3 The first sub-guide groove segment 405 is inclined upwards and the second sub-guide groove segment 406 is inclined downwards. Alternatively, the first sub-guide groove segment 405 can be inclined downwards and the second sub-guide groove segment 406 can be inclined upwards.

[0110] As the air guide plate 30 opens, the extension direction of the second rack 201 (which is roughly the same as the length direction of the second rack 201) is opposite to the extension direction of the first sub-guide groove segment 405 and the second sub-guide groove segment 406. This allows the second rack 201 to quickly change its direction of movement during the movement, thereby driving the air guide plate 30 to quickly adjust the air guide angle, achieving rapid switching of the air outlet direction, realizing cooling and heating modes, improving the air conditioner's response speed and adjustment efficiency, and meeting the user's need for rapid switching of the air conditioner's air outlet direction in different scenarios.

[0111] Optionally, such as Figure 3 As shown, both the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are curves, and the curvature centers of the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are located on opposite sides of the second guide groove.

[0112] The curvature center of the first sub-guide groove segment 405 is located below the second guide groove, and the curvature center of the second sub-guide groove segment 406 is located above the second guide groove. That is, the bending direction of the first sub-guide groove segment 405 is different from the bending direction of the second sub-guide groove segment 406. When the second guide post moves along the first sub-guide groove segment 405, the second rack 201 pushes the air guide plate 30 to rotate around the first rotating shaft 102, so that the air guide plate 30 rotates downward. When the second rack 201 moves along the second sub-guide groove segment 406, the second rack 201 pushes the air guide plate 30 to rotate around the first rotating shaft 102, so that the air guide plate 30 rotates upward.

[0113] Alternatively, the curvature center of the first sub-guide groove segment 405 may be located above the second guide groove, and the curvature center of the second sub-guide groove segment 406 may be located below the second guide groove. That is, the bending direction of the first sub-guide groove segment 405 and the bending direction of the second sub-guide groove segment 406 are different. When the second rack 201 moves along the first sub-guide groove segment 405, the second rack 201 pushes the air guide plate 30 to rotate around the first rotating shaft 102, causing the air guide plate 30 to rotate upward. When the second rack 201 moves along the second sub-guide groove segment 406, the second rack 201 pushes the air guide plate 30 to rotate around the first rotating shaft 102, causing the air guide plate 30 to rotate downward.

[0114] Figures 4 to 7 The central air guide vane is in the same open position, not the closed position; for example... Figures 9 to 11 In the middle, the air guide plate is in the closed position.

[0115] When both the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are arc-shaped, the curvature center is the center of the circle in the statement "the curvature center of the first sub-guide groove segment 405 and the curvature center of the second sub-guide groove segment 406 are located on opposite sides of the second guide groove".

[0116] Optionally, the first sub-guide groove segment 405 is straight or arc-shaped, and the second sub-guide groove segment 406 is straight or arc-shaped.

[0117] When the first sub-guide groove segment 405 is straight, the second sub-guide groove segment 406 can be either straight or arc-shaped. When the first sub-guide groove segment 405 is arc-shaped, the second sub-guide groove segment 406 can be either straight or arc-shaped.

[0118] When both the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are straight, they are not collinear. When both the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are arc-shaped, they are not located on the same circumference. This allows the second rack 201 to quickly change its direction of movement during operation, thereby driving the air guide plate 30 to quickly adjust the air guide angle, achieving rapid switching of the air outlet direction, realizing cooling and heating modes, improving the air conditioner's response speed and adjustment efficiency, and meeting users' needs for rapid switching of the air conditioner's air outlet direction in different scenarios.

[0119] The number of second guide parts 205 is one or more, and the number of second guide mating parts 402 is equal to the number of second guide parts 205 and corresponds one-to-one.

[0120] like Figure 3 As shown, there are multiple second guide posts and multiple second guide grooves.

[0121] The fact that multiple second guide grooves have the same shape can simplify the structure and processing cost of the drive device used for the air conditioning guide plate 30, and can better control the movement trajectory of the second rack 201 and simplify the design process of the movement trajectory of the second rack 201.

[0122] At least two of the extended lines of the second guide grooves intersect, meaning that not all the second guide grooves are parallel to each other. Thus, during the movement of the air guide plate 30, the second rack 201 does not perform translational motion, but rather rotation, thereby driving the air guide plate 30 to rotate around the first rotation axis 102.

[0123] like Figure 3 As shown, the second guide groove is provided on the surface of the second rack 201 away from the second rack 201, and the mechanism box 40 is provided with a second guide post. The second guide groove is straight or arc-shaped, and the shape of the second guide groove is the same as the movement trajectory of the second rack 201.

[0124] The mechanism box 40 includes a first box cover 403 and a second box cover 404 that are assembled together. The first box cover 403, the first rack 101, the second rack 201 and the second box cover 404 are arranged in sequence. The first guide mating part 401 is provided on the first box cover 403 and the second guide mating part 402 is provided on the second box cover 404.

[0125] A second aspect of this utility model provides an air conditioner, including an indoor unit, the indoor unit including: an air guide plate 30; a driving device for the air guide plate 30 as described in any one of the embodiments, wherein a first rack 101 is directly rotatably connected to the air guide plate 30 via a first rotating shaft 102, and a second rack 201 is directly rotatably connected to the air guide plate 30 via a second rotating shaft 202.

[0126] The air conditioner provided in the second aspect of this utility model includes a driving device for the air conditioner air guide plate 30 as described in any of the above embodiments, and therefore has all the beneficial effects of the driving device for the air conditioner air guide plate 30 as described in any of the above embodiments, which will not be repeated here.

[0127] Example 2:

[0128] like Figures 14 to 26 As shown, a drive device for an air conditioning deflector 30 includes a drive wheel 301, a first rack 101, and a connecting rod 20. Unlike Embodiment 1, the drive unit includes a crank 601.

[0129] like Figure 17 and Figure 21 As shown, the drive wheel 301 rotates under control, including a first toothed portion 206 and a crank 601; the first rack 101 meshes with the first toothed portion 206 and is directly rotatably connected to the air guide plate 30 through a first rotating shaft 102. For example, the first rack 101 is provided with a first shaft hole 501, the first rotating shaft 102 is fixedly mounted on the air guide plate 30, and the first rotating shaft 102 passes through the first shaft hole 501 and is rotatably connected to the first shaft hole 501; the connecting rod 20 is slidably connected to the crank 601 and is directly rotatably connected to the air guide plate 30 through a second rotating shaft 202. For example, the connecting rod 20 is provided with a second shaft hole 502, the second rotating shaft 202 is fixedly mounted on the air guide plate 30, and the second rotating shaft 202 passes through the second shaft hole 502 and is rotatably connected to the second shaft hole 502; the drive wheel 301 rotates, driving the first rack 101 and the connecting rod 20 to move, thereby driving the air guide plate 30 to open and close.

[0130] During the opening of the air guide plate 30, the movement trajectory of the first rack 101 is a straight line or an arc, so that the connecting rod 20 drives the air guide plate 30 to rotate around the first rotating shaft 102.

[0131] The first rack 101 is a one-piece structure, directly rotatably connected to the air guide plate 30 via the first rotating shaft 102. No other connecting rods 603 connect the first rack 101 to the air guide plate 30. The connecting rod 20 is also a one-piece structure, directly rotatably connected to the air guide plate 30 via the second rotating shaft 202. No other connecting rods 603 connect the connecting rod 20 to the air guide plate 30. Furthermore, both the first rack 101 and the connecting rod 20 are rotatably connected to the air guide plate 30, rather than slidingly connected, thus avoiding wear on the first rack 101 and the connecting rod 20 during sliding.

[0132] In this application, during the opening of the air guide plate 30, the movement trajectory of the first rack 101 is a straight line or an arc. The cooperation between the crank 601 and the connecting rod 20 drives the connecting rod 20 to move. The movement of the connecting rod 20 can drive the air guide plate 30 to rotate around the first rotating shaft 102, thereby realizing the cooling and heating modes of the air conditioner.

[0133] In other words, by limiting the movement trajectory of the first rack 101, the connecting rod 20 can drive the air guide plate 30 to rotate around the first rotating shaft 102, thereby realizing the up and down air guiding of the air guide plate 30, that is, realizing the cooling and heating mode of the air conditioner, without the need to set the connecting rod 603 or the sliding connection, which simplifies the structure of the driving device for the air conditioner air guide plate 30. It also eliminates the need for controlling the first transmission tooth and the transmission gear, and the second transmission tooth and the transmission gear to not mesh simultaneously, which also simplifies the structure of the driving device for the air conditioner air guide plate 30.

[0134] Optionally, the first rack 101 includes a straight segment or an arc segment, and the gear teeth that mesh with the first tooth portion 206 are located on the straight segment or the arc segment. For example... Figure 19 As shown, the first rack 101 includes a straight segment.

[0135] The first rack 101 includes a straight segment or an arc segment, the shape of which is precisely matched to the movement trajectory (straight or arc) of the first rack 101. This design ensures that the first rack 101 can move smoothly along a predetermined trajectory (straight or arc) when meshing with the first tooth 206, avoiding movement deviations or jamming caused by shape mismatch. For example, when the movement trajectory of the first rack 101 is a straight line, the design of the straight segment ensures that it (the first rack 101) maintains stable straight movement during the movement; when the movement trajectory is an arc, the design of the arc segment allows it (the first rack 101) to move smoothly along the arc trajectory, thereby achieving precise control of the air guide plate 30.

[0136] The first rack 101 may not include a straight section or a circular arc section. Instead, the first rack 101 may include a non-circular arc curved section, and the gear teeth that mesh with the first tooth 206 are located on the curved section. In this case, the first tooth 206 may be a non-circular gear.

[0137] Optionally, during the opening of the air guide plate 30, the movement trajectory of the connecting rod 20 is a variable trajectory line, that is, neither a straight line nor a circular arc.

[0138] During the opening of the air guide vane 30, the movement trajectory of the connecting rod 20 is neither linear nor circular. This unconventional movement trajectory design allows the connecting rod 20 to rotate around the first rotating shaft 102 when it is engaged with the crank 601. This enables the air guide vane 30 to achieve more complex and diverse movement forms during the opening process, thereby better meeting the special requirements of the air conditioner for the movement trajectory of the air guide vane 30 in different operating modes, and further improving the air guiding effect and comfort of the air conditioner.

[0139] Optionally, during the opening of the air guide plate 30, the motion trajectory of the connecting rod 20 includes a first trajectory segment and a second trajectory segment connected in sequence; along the extension direction of the connecting rod 20 during the opening of the air guide plate 30, the extension directions of the first trajectory segment and the second trajectory segment are opposite.

[0140] Along the direction of movement of the connecting rod 20 during the opening of the air guide plate 30, the first trajectory segment and the second trajectory segment are set sequentially. Along the extension direction of the connecting rod 20, the extension directions of the first trajectory segment and the second trajectory segment are opposite. For example, the first trajectory segment is inclined upward and the second trajectory segment is inclined downward, or the first trajectory segment is inclined downward and the second trajectory segment is inclined upward.

[0141] As the air guide plate 30 opens, the extension direction of the connecting rod 20 (which is roughly the same as the length direction of the connecting rod 20) is opposite to the extension direction of the first and second trajectory segments. This allows the connecting rod 20 to quickly change its direction of movement during the movement, thereby driving the air guide plate 30 to quickly adjust the air guide angle and achieve rapid switching of the air outlet direction. This enables the air to switch between cooling and heating modes, improves the air conditioner's response speed and adjustment efficiency, and meets the user's need for rapid switching of the air outlet direction in different scenarios.

[0142] Optionally, both the first trajectory segment and the second trajectory segment are curves, and the curvature centers of the first trajectory segment and the second trajectory segment are located on opposite sides of the motion trajectory of the connecting rod 20.

[0143] The curvature center of the first trajectory segment is located below the motion trajectory of the connecting rod 20, and the curvature center of the second trajectory segment is located above the motion trajectory of the connecting rod 20. That is, the bending direction of the first trajectory segment and the bending direction of the second trajectory segment are different. When the connecting rod 20 moves along the first trajectory segment, the connecting rod 20 pushes the air guide plate 30 to rotate around the first rotation axis 102, so that the air guide plate 30 rotates downward. When the connecting rod 20 moves along the second trajectory segment, the connecting rod 20 pushes the air guide plate 30 to rotate around the first rotation axis 102, so that the air guide plate 30 rotates upward.

[0144] Alternatively, the curvature center of the first trajectory segment may be located above the motion trajectory of the connecting rod 20, and the curvature center of the second trajectory segment may be located below the motion trajectory of the connecting rod 20. That is, the bending direction of the first trajectory segment and the bending direction of the second trajectory segment are different. When the connecting rod 20 moves along the first trajectory segment, the connecting rod 20 pushes the air guide plate 30 to rotate around the first rotation axis 102, causing the air guide plate 30 to rotate upward. When the connecting rod 20 moves along the second trajectory segment, the connecting rod 20 pushes the air guide plate 30 to rotate around the first rotation axis 102, causing the air guide plate 30 to rotate downward.

[0145] When both the first and second trajectory segments are circular arcs, the curvature center is the center of the circle in the statement "the curvature center of the first trajectory segment and the curvature center of the second trajectory segment are located on opposite sides of the motion trajectory of the connecting rod 20".

[0146] Optionally, the first trajectory segment is a straight line or an arc, and the second trajectory segment is a straight line or an arc.

[0147] When the first trajectory segment is a straight line, the second trajectory segment can be either a straight line or an arc. When the first trajectory segment is an arc, the second trajectory segment can be either a straight line or an arc.

[0148] When both the first and second trajectory segments are straight lines, they are not collinear. When both the first and second trajectory segments are circular arcs, they are not located on the same circumference. This allows the connecting rod 20 to quickly change its direction of motion during movement, thereby driving the air guide plate 30 to quickly adjust its air guide angle, achieving rapid switching of the air outlet direction, realizing cooling and heating modes, improving the air conditioner's response speed and adjustment efficiency, and meeting users' needs for rapid switching of the air conditioner's air outlet direction in different scenarios.

[0149] Optionally, such as Figure 17 As shown, the first tooth 206 is a cylindrical gear.

[0150] Optionally, such as Figure 21 As shown, the first tooth 206 rotates synchronously with the crank 601.

[0151] The axes of the first tooth 206 and the crank 601 coincide.

[0152] The driving device for the air conditioning deflector 30 also includes a motor 10, which is driven by the first tooth 206 or the crank 601. The first tooth 206 and the crank 601 are fixedly connected to drive the first tooth 206 and the crank 601 to rotate. In this way, only one motor 10 is needed to drive the first rack 101 and the connecting rod 20 to move simultaneously.

[0153] Optionally, such as Figure 21 As shown, the crank 601 includes a mounting portion 602 and a connecting rod 603. The mounting portion 602 is fixedly connected to the first tooth portion 206; the connecting rod 603 is fixedly connected to the mounting portion 602 and protrudes from the outside of the mounting portion 602; wherein, one of the connecting rod 603 and the connecting rod 20 is provided with a sliding groove 604, and the other is provided with a sliding post 208, the sliding post 208 is located in the sliding groove 604 and can slide relative to the sliding groove 604.

[0154] A connecting rod 603 is disposed between the mounting part 602 and the connecting rod 20 to connect the mounting part 602 and the connecting rod 20. A sliding column 208 is located in a sliding groove 604 and can slide relative to the sliding groove 604 to realize the rotation of the drive wheel 301, so that the crank 601 drives the connecting rod 20 to move.

[0155] Optionally, such as Figure 14 , Figure 18 and Figure 21 As shown, the drive device for the air conditioning deflector 30 also includes a mechanism box 40, in which the first rack 101, connecting rod 20, first tooth 206, and crank 601 are all disposed, and move between the position of extending out of the mechanism box 40 and the position of retracting the mechanism box 40.

[0156] like Figure 18 , Figure 19 and Figure 23 As shown, the first rack 101 is provided with a first guide part 103, and the mechanism box 40 is provided with a first guide mating part 401. During the movement of the first rack 101, the first guide part 103 and the first guide mating part 401 cooperate to guide the movement trajectory of the first rack 101, so that the first rack 101 always moves along the predetermined trajectory, thereby improving the guiding accuracy of the movement of the first rack 101 and ensuring the accuracy and stability of the movement of the air guide plate 30.

[0157] One of the first guide portion 103 and the first guide mating portion 401 is a first guide groove, and the other is a first guide post. The first guide post is located in the first guide groove and can slide along the length direction of the first guide groove.

[0158] like Figure 19As shown, the first guide groove is provided on the surface of the first rack 101 away from the connecting rod 20, and the mechanism box 40 is provided with a first guide post. The first guide groove is straight or arc-shaped, and the shape of the first guide groove is the same as the movement trajectory of the first rack 101.

[0159] The number of first guide parts 103 is one or more, and the number of first guide mating parts 401 is equal to the number of first guide parts 103 and corresponds one-to-one.

[0160] like Figure 16 , Figure 20 and Figure 21 As shown, the connecting rod 20 is provided with a second guide part 205, and the mechanism box 40 is provided with a second guide mating part 402. During the movement of the connecting rod 20, the second guide part 205 and the second guide mating part 402 cooperate to guide the movement trajectory of the connecting rod 20, so that the connecting rod 20 always moves along the predetermined trajectory, thereby improving the guiding accuracy of the movement of the connecting rod 20 and ensuring the accuracy and stability of the movement of the air guide plate 30.

[0161] One of the second guide portion 205 and the second guide mating portion 402 is a second guide groove, and the other is a second guide post. The second guide post is located in the second guide groove and can slide along the length direction of the second guide groove.

[0162] The second guide groove includes a first sub-guide groove segment 405 and a second sub-guide groove segment 406 that are connected. During the opening of the air guide plate 30, the second guide column slides through the first sub-guide groove segment 405 and the second sub-guide groove segment 406 in sequence.

[0163] like Figure 21 As shown, along the extension direction of the connecting rod 20 during the opening of the air guide plate 30, the extension directions of the first sub-guide groove section 405 and the second sub-guide groove section 406 are opposite.

[0164] Along the direction of movement of the connecting rod 20 during the opening of the air guide plate 30, the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are sequentially arranged. Along the extension direction of the connecting rod 20, the extension directions of the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are opposite. For example, the first sub-guide groove segment 405 is inclined upward and the second sub-guide groove segment 406 is inclined downward, or the first sub-guide groove segment 405 is inclined downward and the second sub-guide groove segment 406 is inclined upward.

[0165] As the air guide plate 30 opens, the extension direction of the connecting rod 20 (which is roughly the same as the length direction of the connecting rod 20) is opposite to the extension direction of the first sub-guide groove segment 405 and the second sub-guide groove segment 406. This allows the connecting rod 20 to quickly change its direction of movement during the movement, thereby driving the air guide plate 30 to quickly adjust the air guide angle, achieving rapid switching of the air outlet direction, realizing cooling and heating modes, improving the air conditioner's response speed and adjustment efficiency, and meeting the user's need for rapid switching of the air conditioner's air outlet direction in different scenarios.

[0166] Optionally, such as Figure 21 As shown, both the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are curves, and the curvature centers of the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are located on opposite sides of the second guide groove.

[0167] The curvature center of the first sub-guide groove segment 405 is located below the second guide groove, and the curvature center of the second sub-guide groove segment 406 is located above the second guide groove. That is, the bending direction of the first sub-guide groove segment 405 is different from the bending direction of the second sub-guide groove segment 406. When the second guide post moves along the first sub-guide groove segment 405, the connecting rod 20 pushes the air guide plate 30 to rotate around the first rotating shaft 102, so that the air guide plate 30 rotates downward. When the connecting rod 20 moves along the second sub-guide groove segment 406, the connecting rod 20 pushes the air guide plate 30 to rotate around the first rotating shaft 102, so that the air guide plate 30 rotates upward.

[0168] Alternatively, the center of curvature of the first sub-guide groove segment 405 may be located above the second guide groove, and the center of curvature of the second sub-guide groove segment 406 may be located below the second guide groove. That is, the bending direction of the first sub-guide groove segment 405 and the bending direction of the second sub-guide groove segment 406 are different. When the connecting rod 20 moves along the first sub-guide groove segment 405, the connecting rod 20 pushes the air guide plate 30 to rotate around the first rotating shaft 102, causing the air guide plate 30 to rotate upward. When the connecting rod 20 moves along the second sub-guide groove segment 406, the connecting rod 20 pushes the air guide plate 30 to rotate around the first rotating shaft 102, causing the air guide plate 30 to rotate downward.

[0169] When both the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are arc-shaped, the curvature center is the center of the circle in the statement "the curvature center of the first sub-guide groove segment 405 and the curvature center of the second sub-guide groove segment 406 are located on opposite sides of the second guide groove".

[0170] Optionally, the first sub-guide groove segment 405 is straight or arc-shaped, and the second sub-guide groove segment 406 is straight or arc-shaped.

[0171] When the first sub-guide groove segment 405 is straight, the second sub-guide groove segment 406 can be either straight or arc-shaped. When the first sub-guide groove segment 405 is arc-shaped, the second sub-guide groove segment 406 can be either straight or arc-shaped.

[0172] When both the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are straight, they are not collinear. When both the first sub-guide groove segment 405 and the second sub-guide groove segment 406 are arc-shaped, they are not located on the same circumference. This allows the connecting rod 20 to quickly change its direction of movement during operation, thereby driving the air guide plate 30 to quickly adjust the air guide angle, achieving rapid switching of the air outlet direction, realizing cooling and heating modes, improving the air conditioner's response speed and adjustment efficiency, and meeting the user's need for rapid switching of the air conditioner's air outlet direction in different scenarios.

[0173] in, Figures 15 to 17 , Figure 21 In the middle, all air guide vanes are in the closed position; Figures 22 to 26 In the middle, the air guide vanes are all in the same position and are not in the closed position.

[0174] The number of second guide parts 205 is one or more, and the number of second guide mating parts 402 is equal to the number of second guide parts 205 and corresponds one-to-one.

[0175] like Figure 20 and Figure 21 As shown, there are multiple second guide posts and multiple second guide grooves.

[0176] The fact that multiple second guide grooves have the same shape can simplify the structure and processing cost of the drive device used for the air conditioning air guide plate 30, and can better control the movement trajectory of the link 20 and simplify the design process of the movement trajectory of the link 20.

[0177] At least two of the extended lines of the second guide grooves intersect, meaning that not all the second guide grooves are parallel to each other. Thus, during the movement of the air guide plate 30, the connecting rod 20 does not perform translational motion, but rather rotation, thereby causing the air guide plate 30 to rotate around the first rotation axis 102.

[0178] The mechanism box 40 is provided with a second guide post, and the second guide groove is straight or arc-shaped. The shape of the second guide groove is the same as the movement trajectory of the connecting rod 20.

[0179] like Figure 18 and Figure 20As shown, the mechanism box 40 includes a first box cover 403 and a second box cover 404 that are assembled together. The first box cover 403, the first rack 101, the connecting rod 20 and the second box cover 404 are arranged in sequence. The first guide fitting part 401 is provided on the first box cover 403 and the second guide fitting part 402 is provided on the second box cover 404.

[0180] Optionally, such as Figure 21 As shown, the connecting rod 20 is provided with a relief groove 209, and the connecting rod 603 is at least partially disposed in the relief groove 209.

[0181] The connecting rod 603 is located on the side of the connecting rod 20 away from the first rack 101. The side of the connecting rod 20 away from the rack is provided with a relief groove 209. The connecting rod 603 is at least partially located in the relief groove 209. This can reduce the thickness of the driving device used for the air conditioning guide plate 30, and also prevent the setting of the connecting rod 603 from affecting the cooperation between the second guide part 205 and the second guide mating part 402.

[0182] A second aspect of this utility model provides an air conditioner, including an indoor unit, the indoor unit including: an air guide plate 30; a driving device for the air guide plate 30 as described in any one of the embodiments, wherein a first rack 101 is directly rotatably connected to the air guide plate 30 via a first rotating shaft 102, and a connecting rod 20 is directly rotatably connected to the air guide plate 30 via a second rotating shaft 202.
