[0055] 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.

[0056] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0057] Combination Figures 1-14 As shown, this embodiment of the present disclosure provides an air guide plate assembly for an indoor unit 100. The indoor unit 100 includes a housing with an air outlet 1001. The air guide plate assembly includes a first air guide plate 10, a second air guide plate 20, a first connecting rod 30, and a second connecting rod 40.

[0058] The second air guide plate 20 and the first air guide plate 10 are arranged sequentially along the width direction of the air outlet 1001.

[0059] The air outlet 1001 includes a first air outlet area 1002 and a second air outlet area 1003, which are arranged sequentially along the width direction of the air outlet 1001. A first air guide plate 10 is disposed in the first air outlet area 1002 and is used to open or close the first air outlet area 1002, wherein, for example... Figure 13 As shown, when the first air guide plate 10 opens the first air outlet area 1002, the first air guide plate 10 is in the open position, as... Figure 6 As shown, when the first air guide plate 10 covers the first air outlet area 1002, the first air guide plate 10 is in the closed position. The second air guide plate 20 is disposed in the second air outlet area 1003 and is used to open or close the second air outlet area 1003, wherein, as shown... Figure 14 As shown, when the second air guide plate 20 opens the second air outlet area 1003, the second air guide plate 20 is in the open position, as... Figure 6 As shown, when the second air guide plate 20 covers the second air outlet area 1003, the second air guide plate 20 is in the closed position.

[0060] The first air guide plate 10 and the second air guide plate 20 are set to control the first air outlet area 1002 and the second air outlet area 1003 respectively, thereby effectively changing the air outlet area of ​​the air outlet 1001 and meeting people's diverse air outlet needs.

[0061] The first link 30 is connected to the first air guide plate 10 and is used to drive the first air guide plate 10 to move between the open position and the closed position; the second link 40 is connected to the second air guide plate 20 and is used to drive the second air guide plate 20 to move between the open position and the closed position.

[0062] Among them, such as Figure 12 As shown, the motion trajectory of the second link 40 is arc-shaped, and the motion trajectory of the first link 30 is located inside the motion trajectory of the second link 40. The side closer to the center of the arc is the inner side, and the side farther from the center of the arc is the outer side.

[0063] The movement trajectory of the first link 30 is located on the center side of the movement trajectory (arc) of the second link 40. This reduces the space occupied by the movement of the first link 30, thereby making the entire air guide plate assembly occupy less space.

[0064] Optionally, the air guide plate assembly also includes a housing 50, and a first link 30 and a second link 40 move between an extended position extending from the housing 50 and a retracted position retracting from the housing 50. The housing 50 is provided with a limiting structure, and the second link 40 is provided with a limiting engagement structure. The limiting structure and the limiting engagement structure cooperate to guide the second link 40 to move relative to the housing 50 between the extended position and the retracted position, so that the second link 40 moves between the extended position and the retracted position according to a preset motion trajectory, avoiding deviation during the movement.

[0065] When the second link 40 is in the extended position, it drives the second air guide plate 20 to the open position; when the second link 40 is in the retracted position, it drives the second air guide plate 20 to the closed position.

[0066] When both the first air guide plate 10 and the second air guide plate 20 are in the closed position, the first connecting rod 30 is located inside the limiting structure or the limiting cooperation structure.

[0067] When both the first air guide plate 10 and the second air guide plate 20 are in the closed position, if the first connecting rod 30 is located outside the limiting structure or the limiting cooperation structure, the space occupied by the first connecting rod 30 cannot be ignored when designing the entire air guide plate assembly, thus increasing the space occupied by the entire air guide plate assembly.

[0068] When both the first air guide plate 10 and the second air guide plate 20 are in the closed position, if the first link 30 intersects with the limiting structure or the limiting mating structure, the second link 40 will interfere with the first link 30 when it moves along the limiting structure.

[0069] Therefore, when both the first air guide plate 10 and the second air guide plate 20 are in the closed position, the first connecting rod 30 is located inside the limiting structure or the limiting fit structure, which can reduce the space occupied by the entire air guide plate assembly and avoid interference between the movement of the first connecting rod 30 and the second connecting rod 40.

[0070] Optionally, such as Figure 13 As shown, when the first air guide plate 10 is in the open position, the end of the first air guide plate 10 closest to the second air guide plate 20 in the closed position is located inside the other end of the first air guide plate 10; as Figure 14 As shown, when the second air guide plate 20 is in the open position, the end of the second air guide plate 20 near the first air guide plate 10 in the closed position is located inside the other end of the second air guide plate 20. The direction closer to the middle of the indoor unit 100 is called the inside, and the direction away from the middle of the indoor unit 100 is called the outside.

[0071] Taking the first air guide plate 10 located above the second air guide plate 20 as an example, the end of the first air guide plate 10 near the second air guide plate 20 in the closed position is the lower end of the first air guide plate 10, and the other end of the first air guide plate 10 is the upper end; the end of the second air guide plate 20 near the first air guide plate 10 in the closed position is the upper end of the second air guide plate 20, and the other end of the second air guide plate 20 is the lower end.

[0072] When both the first air guide plate 10 and the second air guide plate 20 are in the open position, they will roughly form a figure-eight shape. The first air guide plate can move synchronously or independently.

[0073] When cooling, the first air guide plate 10 is opened to achieve upward airflow; when heating, the second air guide plate 20 is opened to achieve downward airflow.

[0074] Optionally, such as Figure 6 and Figure 13 As shown, when the first air guide plate 10 moves from the closed position to the open position, the trajectory of the first connecting rod 30 extends from the second air guide plate 20 to the first air guide plate 10; as Figure 6 and Figure 14 As shown, when the second air guide plate 20 moves from the closed position to the open position, the movement trajectory of the second link 40 extends from the first air guide plate 10 to the second air guide plate 20.

[0075] During the opening of the first air guide plate 10 and the second air guide plate 20, the extension direction of the movement trajectory of the first link 30 and the second link 40 ensures that the first link 30 and the second link 40 only occupy the space in the direction from the first air guide plate 10 to the second air guide plate 20, and occupy less space in the width direction of the indoor unit 100, thus requiring less structural modification to the indoor unit 100.

[0076] Optionally, the first link 30 is fixedly connected to the first air guide plate 10. The movement trajectory of the first link 30 includes an arc segment, which can simplify the connection between the first link 30 and the first air guide plate 10, avoid failure at the connection between the first link 30 and the first air guide plate 10, and enable the first air guide plate 10 to be closed and opened.

[0077] Optionally, the second link 40 includes a first sub-link 402 and a second sub-link 403.

[0078] The first sub-link 402 is rotatably connected to the second air guide plate 20; the second sub-link 403 is rotatably connected to the second air guide plate 20; wherein, when the second air guide plate 20 moves from the closed position to the open position, the movement trajectories of the first sub-link 402 and the second sub-link 403 are both arc-shaped.

[0079] The motion trajectory of the first connecting rod 402 (e.g.)Figure 11 The arc where serial number 510 is located) and the motion trajectory of the second sub-link 403 (such as...) Figure 7 The intersection of the arc (where serial number 507 is located) reduces the space occupied by the movement of the first sub-link 402 and the second sub-link 403, further reducing the space occupied by the entire air guide plate assembly. On the other hand, if the two do not intersect, gears need to be set up in related technologies to mesh with the first sub-link 402 and the second sub-link 403 sequentially to achieve the predetermined trajectory of the second air guide plate 20. However, in this application, the first sub-link 402 and the second sub-link 403 can start moving simultaneously during the opening of the second air guide plate 20, without needing to start sequentially. Therefore, the intersection simplifies the driving method of the first sub-link 402 and the second sub-link 403, and simplifies the structure of the air guide plate assembly, when the first sub-link 402 is rotatably connected to the first air guide plate 10 and the second sub-link 403 is rotatably connected to the second air guide plate 20.

[0080] When the second air guide plate 20 moves from the closed position to the open position, the movement trajectory of the first sub-link 402 and the movement trajectory of the second sub-link 403 both extend from the first air guide plate 10 to the second air guide plate 20.

[0081] Optionally, such as Figure 6 As shown, the rotatable connection between the second sub-connecting rod 403 and the second air guide plate 20 is located on the side opposite to the rotatable connection between the first sub-connecting rod 402 and the second air guide plate 20.

[0082] Taking the first air guide plate 10 located above the second air guide plate 20 as an example, the rotatable connection between the second sub-connecting rod 403 and the second air guide plate 20 is located below the rotatable connection between the first sub-connecting rod 402 and the second air guide plate 20.

[0083] When the second air guide plate 20 moves from the closed position to the open position, at least one of the movement trajectories of the first sub-link 402 and the second sub-link 403 can be a straight line or a non-arc curve.

[0084] During the opening of the second air guide plate 20, the first sub-link 402 and the second sub-link 403 move simultaneously, that is, they start moving and stop moving at the same time, rather than starting moving one after the other. This can shorten the time it takes for the second air guide plate 20 to move to the target position and improve the response speed of the second air guide plate.

[0085] Optionally, such as Figure 6As shown, the second sub-connecting rod 403 includes a second sub-connecting rod body 4031 and a transmission rod 4032. The transmission rod 4032 is located between the second sub-connecting rod body 4031 and the second air guide plate 20. One end of the transmission rod 4032 is rotatably connected to the second sub-connecting rod body 4031, and the other end of the transmission rod 4032 is rotatably connected to the second air guide plate 20.

[0086] The transmission rod 4032 is designed such that the degree of freedom of movement between the second sub-connecting rod body 4031 and the second air guide plate 20 is greater than that between the first sub-connecting rod 402 and the second air guide plate 20. Thus, when the rotational connection between the second sub-connecting rod 403 and the second air guide plate 20 is located on the side away from the first air guide plate 10 at the rotational connection between the first sub-connecting rod 402 and the second air guide plate 20, and the movement trajectory of the first sub-connecting rod 402 intersects with the movement trajectory of the second sub-connecting rod 403, the second air guide plate 20 can be opened.

[0087] Optionally, such as Figure 6 As shown, when the second air guide plate 20 is in the closed position, the second sub-connecting rod 403 is located on the side of the first sub-connecting rod 402 away from the second air guide plate 20; as Figure 14 As shown, when the second air guide plate 20 is in the open position, the second sub-link 403 is located on the side of the first sub-link 402 facing the second air guide plate 20. Thus, when the second air guide plate 20 moves from the closed position to the open position, the movement trajectory of the first sub-link 402 intersects with the movement trajectory of the second sub-link 403.

[0088] Furthermore, due to the presence of the transmission rod 4032, the second sub-link 403 has a large degree of freedom of movement with respect to the second air guide plate 20. The second sub-link 403 moves more flexibly. Therefore, in the closed position of the second air guide plate 20, the second sub-link 403 is farther away from the second air guide plate 20, while the first sub-link 402 moves closer to the second air guide plate 20. In the open position of the second air guide plate 20, the second sub-link 403, with its flexible movement capability, can make a large-angle deflection and move to a position closer to the second air guide plate 20. The first sub-link 402 has a weaker deflection capability than the second sub-link 403, and moves to a position farther away from the second air guide plate 20.

[0089] Optionally, during the process of the second air guide plate 20 opening from the closed position to the open position, the movement speed of the first sub-link 402 is greater than that of the second sub-link, the radius of the circle containing the movement trajectory (arc) of the first sub-link 402 is greater than the radius of the circle containing the movement trajectory (arc) of the second sub-link, and the central angle corresponding to the movement trajectory of the first sub-link 402 is smaller than the central angle corresponding to the movement trajectory of the second sub-link.

[0090] like Figure 6As shown, the first sub-link 402 includes a first sub-link body 4021 and a connecting rod 4022.

[0091] The connecting rod 4022 is located between the first sub-connecting rod body 4021 and the second air guide plate 20. One end of the connecting rod 4022 is fixedly connected to the first sub-connecting rod body 4021 and the connection point is bent. The other end of the connecting rod 4022 is rotatably connected to the second air guide plate 20.

[0092] like Figure 12 As shown, the second air guide plate 20 includes a first end 201 and a second end 202, which are arranged sequentially along the width direction of the air outlet 1001. In the open position of the second air guide plate 20, the second end 202 of the second air guide plate 20 is located outside the first end 201, wherein the direction away from the center of the indoor unit 100 is called outward, and the direction closer to the center of the indoor unit 100 is called inward.

[0093] During the movement of the second air guide plate 20 from the closed position to the open position, the movement trajectory of the first sub-link body 4021 is arc-shaped. Due to the deflection angle of the second sub-link 403, the second sub-link 403 pushes the second end 202 of the second air guide plate 20 to move outward. The second air guide plate 20 rotates around the rotational connection between the connecting rod 4022 and the second air guide plate 20 until it moves to the open position.

[0094] The connection points between the first sub-link 402 and the second air guide plate 20, and the connection points between the second sub-link 403 and the second air guide plate 20, are sequentially arranged from the first end 201 to the second end 202.

[0095] The deflection capacity of the second sub-link 403 is stronger than that of the first sub-link 402. Therefore, the rotational connection between the second sub-link 403 and the second air guide plate 20 is set close to the second end 202, and the rotational connection between the first sub-link 402 and the second air guide plate 20 is set close to the first end 201. In other words, the rotational connection between the first sub-link 402 and the second air guide plate 20 and the rotational connection between the transmission rod 4032 and the second air guide plate 20 are set sequentially along the direction from the first end 201 to the second end 202.

[0096] Optionally, the air guide plate assembly also includes a drive unit 60.

[0097] The drive device 60 is driven to both the first sub-link 402 and the second sub-link 403, and is used to drive the first sub-link 402 and the second sub-link 403 to perform differential motion, and the movement speed of the first sub-link 402 is greater than the movement speed of the second sub-link 403, so that when the second air guide plate 20 moves to the open position, the first end 201 is located inside the second end 202.

[0098] Optionally, such as Figure 12As shown, the drive unit 60 includes a drive gear 603. (As indicated...) Figure 8 and Figure 9 As shown, the first connecting rod 30 is provided with a first gear tooth 302 and a second gear tooth 303. In the direction of movement of the first connecting rod 30 during the opening process of the first air guide plate 10 (the process of moving from the closed position to the open position), the second gear tooth 303 and the first gear tooth 302 are arranged in sequence. The first gear tooth 302 is a straight gear tooth extending along the length direction of the first connecting rod 30, and the second gear tooth 303 is an arc-shaped gear tooth extending along the length direction of the first connecting rod 30. During the opening process of the first air guide plate 10, the drive gear 603 meshes with the first gear tooth 302 and the second gear tooth 303 in sequence.

[0099] During the opening of the first air guide plate 10, the drive gear 603 first meshes with the first gear tooth 302. Since the first gear tooth 302 is a straight tooth, when the drive gear 603 meshes with the first gear tooth 302, it can drive the first air guide plate 10 to move in a straight line. When the first air guide plate 10 is in the closed position, there is a non-zero angle between the straight line containing the first gear tooth 302 and the first air guide plate 10, for example, an angle of 90° or close to 90°. This causes the first air guide plate 10 to extend outward when the drive gear 603 meshes with the first gear tooth 302. The direction closer to the center of the indoor unit 100 is considered inward, and the direction farther from the center of the indoor unit 100 is considered outward. The first air guide plate 10 extending outward first can avoid interference with other parts of the indoor unit 100 caused by direct rotation during the opening process.

[0100] After the drive gear 603 disengages from the first gear tooth 302, it meshes with the second gear tooth 303. Since the second gear tooth 303 is an arc-shaped tooth extending along the length of the first connecting rod 30, when the drive gear 603 meshes with the second gear tooth 303, it can drive the first connecting rod 30 to make an arc-shaped motion, thereby driving the air guide plate to rotate.

[0101] The air guide plate assembly also includes a drive element 604, which can be a motor, used to drive the drive gear 603 to rotate. The rotation of the drive gear 603 drives the first connecting rod 30 to move.

[0102] Optionally, the first gear tooth 302 is perpendicular to the first air guide plate 10 in the closed position.

[0103] The first air guide plate 10 is curved, but each small segment of the first air guide plate 10 can be considered a plane after being infinitely divided. One of these small segments has a connecting post 101, which is rotatably connected to the first sub-connecting rod 402. The first gear tooth 302 is perpendicular to the first air guide plate 10 in the closed position, meaning that the first gear tooth 302 is perpendicular to the plane of the small segment containing the connecting post 101 on the first air guide plate 10. Thus, when the drive gear 603 meshes with the first gear tooth 302, the first air guide plate 10 is pushed out along the axis of the air duct, preventing the first air guide plate 10 from shifting and interfering with other parts of the indoor unit 100.

[0104] Optionally, the length of the first gear tooth 302 is less than the length of the second gear tooth 303.

[0105] After the first air guide plate 10 is pushed out a short distance during the opening process, it can avoid interference between the first air guide plate 10 and other parts of the indoor unit 100. Therefore, the length of the first gear tooth 302 is less than the length of the second gear tooth 303.

[0106] Optionally, the first connecting rod 30 is fixedly connected to the first air guide plate 10.

[0107] By setting the shape, position, and movement trajectory of the first link 30, the first link 30 can be fixedly connected to the first air guide plate 10. Compared to the first link 30 being movably connected to the first air guide plate 10 (e.g., rotatably connected), the fixed connection simplifies the connection structure between the first link 30 and the first air guide plate 10 and enhances the reliability of the movement of the first air guide plate 10.

[0108] Optionally, the drive gear 603 is located inside the housing 50, and the first link 30 moves between an extended position extending out of the housing 50 and a retracted position retracting out of the housing 50.

[0109] When the first link 30 is in the retracted position, the first air guide plate 10 is in the closed position. When the first link 30 is in the extended position, the first air guide plate 10 is in the open position.

[0110] like Figure 9 and Figure 11 As shown, the box body 50 is provided with a guide mechanism 502, and the first link 30 is provided with a guide engagement mechanism 304. The guide mechanism 502 and the guide engagement mechanism 304 cooperate to guide the first link 30 to move between the extended position and the retracted position, so as to avoid the first link 30 from deviating during the movement.

[0111] One of the guiding mechanism 502 and the guiding mating mechanism 304 is a guide post and the other is a guide groove. The guide post is located in the guide groove and can move along the guide groove to guide the first connecting rod 30 to first make a linear motion and then make an arc motion.

[0112] The guide groove includes a first sub-guide groove 5021 and a second sub-guide groove 5022. During the opening of the first air guide plate, the first sub-guide groove and the second guide groove are sequentially arranged along the extension direction of the first connecting rod. The first sub-guide groove is straight, and the second sub-guide groove is arc-shaped. When the guide post is located in the first guide groove and engages with it, the drive gear engages with the teeth of the first wheel, the first connecting rod moves linearly, and the first guide plate is pushed outward; when the guide post is located in the second guide groove and engages with it, the drive gear engages with the teeth of the second wheel, the first connecting rod moves arc-shaped, and the first guide plate begins to rotate.

[0113] Optionally, one end of the first link 30 is connected to the first air guide plate 10, and the other end of the first link 30 extends in the direction from the first air guide plate 10 to the second air guide plate 20.

[0114] This configuration allows the drive gear 603 to mesh with the first connecting rod 30, thereby driving the first air guide plate 10 to the open position. When the first air guide plate 10 is in the closed position, the end of the first air guide plate 10 closest to the second air guide plate 20 is located inside the other end of the first air guide plate 10.

[0115] The drive unit 60 includes a drive mechanism. The drive mechanism is driven to move the second link 40, thereby moving the second air guide plate 20 between an open position and a closed position.

[0116] like Figure 6 As shown, the drive mechanism is located between the first link 30 and the second link 40.

[0117] The drive mechanism includes a drive component 601 and a gear set 602, and the second connecting rod 40 is provided with gear teeth.

[0118] The gear set 602 is driven and connected to the drive member 601 and meshes with the gear teeth. The drive member 601 drives the gear set 602 to rotate, and the gear set 602 drives the second connecting rod 40 to move through the gear teeth, so as to realize the opening and closing of the second air guide plate 20. The axis of the gear set 602 is located between the first connecting rod 30 and the second connecting rod 40, which makes the air guide plate assembly compact and occupies little space.

[0119] The drive component 601 can be a motor.

[0120] like Figure 8 As shown, the first link 30 is provided with a clearance groove 301 for avoiding the gear set 602, so as to avoid interference between the first link 30 and the gear set 602.

[0121] Optionally, the first sub-connecting rod 402 is provided with gear teeth; the second sub-connecting rod 403 is provided with gear teeth. The gear set 602 includes a first gear 6021 and a second gear 6022.

[0122] The first gear 6021 meshes with the teeth of the first sub-connecting rod 402; the second gear 6022 meshes with the teeth of the second sub-connecting rod 403; the first gear 6021 drives the first sub-connecting rod 402 to move, and the second gear 6022 drives the second sub-connecting rod 403 to move, so as to jointly drive the second guide vane 20 to move between the open position and the closed position. The first gear 6021 and the second gear 6022 are coaxially connected, and their radii are not equal.

[0123] like Figure 6 As shown, the first gear 6021 and the second gear 6022 are coaxially arranged, so that the first gear 6021 and the second gear 6022 have the same angular velocity, but the radii of the first gear 6021 and the second gear 6022 are not equal, so that the first sub-connecting rod 402 and the second sub-connecting rod 403 have different movement speeds, thereby driving the second guide vane 20 to rotate to the open position.

[0124] The radius of the first gear 6021 is greater than the radius of the second gear 6022, which makes the movement speed of the first sub-link 402 greater than the movement speed of the second sub-link 403.

[0125] Because the first sub-link 402 and the second sub-link 403 move simultaneously, the stroke of the first sub-link 402 is greater than the stroke of the second sub-link 403 during the opening of the second air guide plate 20.

[0126] Optionally, the transmission rod 4032 is provided with a relief groove 4033. When the second air guide plate 20 is in the open position, the connection between the first sub-connecting rod 402 and the second air guide plate 20 is located in the relief groove 4033.

[0127] like Figure 14 As shown, during the opening of the second air guide plate 20, the transmission rod 4032 moves toward the connecting rod 4022. An avoidance groove 4033 is provided on the transmission rod 4032 to prevent the connection between the connecting rod 4022 and the second air guide plate 20 from affecting the movement of the transmission rod 4032.

[0128] Optionally, the second sub-link 403 moves between a retracted position within the housing 50 and an extended position extending out of the housing 50 to drive the second air guide plate 20 between an open position and a closed position; wherein, as Figure 7 As shown, the limiting structure includes a first limiting structure 503 and a second limiting structure 505 provided on the housing 50, such as... Figure 6 As shown, the limiting fit structure includes a first limiting fit structure 4034 that cooperates with the first limiting structure 503 and a second limiting fit structure 4036 that cooperates with the second limiting structure 505, provided on the second sub-link 403, so as to guide the second sub-link 403 to move between the retracted position and the extended position.

[0129] During the opening of the second air guide plate 20, the mating area between the first limiting structure 503 and the first limiting mating structure 4034 decreases, while the mating area between the second limiting structure 505 and the second limiting mating structure 4036 increases.

[0130] During the opening of the second air guide plate 20, the mating area between the first limiting structure 503 and the first limiting engagement structure 4034 decreases, while the mating area between the second limiting structure 505 and the second limiting engagement structure 4036 increases. In other words, during the opening of the second air guide plate 20, the first limiting structure 503 tends to gradually disengage from the first limiting engagement, while the second limiting structure 505 and the second limiting engagement structure 4036 gradually deepen their engagement. Compared to the situation where the first limiting structure 503 and the first limiting engagement structure 4034 maintain a constant mating area throughout the opening process of the second air guide plate 20, and the second limiting structure 505 and the second limiting engagement structure 4036 maintain a constant mating area throughout the opening process, this application can reduce the size of the first limiting structure 503 and the second limiting structure 505, thereby reducing the size of the box body 50.

[0131] One of the first limiting structure 503 and the first limiting mating structure 4034 is a first limiting groove 504, and the other of the first limiting structure 503 and the first limiting mating structure 4034 is a first limiting protrusion 4035. The first limiting protrusion 4035 is located in the first limiting groove 504 and can move relative to the first limiting groove 504, so that the first limiting structure 503 has both a limiting function and a guiding function for the movement of the second sub-link 403 on the first limiting mating structure 4034, preventing the second sub-link 403 from deviating during its movement.

[0132] The number of the first limiting protrusion 4035 can be one or more. For example Figure 3 and Figure 6 As shown, when there is only one first limiting protrusion 4035, the mating area between the first limiting structure 503 and the first limiting mating structure 4034 is reduced, which can be achieved by reducing the portion of the first limiting protrusion 4035 located within the first limiting groove 504. When there are multiple first limiting protrusions 4035, the mating area between the first limiting structure 503 and the first limiting mating structure 4034 is reduced, which can be achieved by reducing the number of first limiting protrusions 4035 located within the first limiting groove 504 among the multiple first limiting protrusions 4035.

[0133] The first limiting groove 504 is arc-shaped and coincides with the movement trajectory of the second sub-connecting rod 403.

[0134] One of the second limiting structure 505 and the second limiting mating structure 4036 is a second limiting groove 4037, and the other of the second limiting structure 505 and the second limiting mating structure 4036 is a second limiting protrusion 506. The second limiting protrusion 506 is located in the second limiting groove 4037 and can move relative to the second limiting groove 4037, so that the second limiting structure 505 has both a limiting function and a guiding function for the movement of the second sub-link 403 on the second limiting mating structure 4036, preventing the second sub-link 403 from deviating during its movement.

[0135] The number of second limiting protrusions 506 can be one or more. When there is only one second limiting protrusion 506, the mating area between the second limiting structure 505 and the second limiting mating structure 4036 is reduced; this can be achieved by reducing the portion of the second limiting protrusion 506 located within the second limiting groove 4037. When there are multiple second limiting protrusions 506, the mating area between the second limiting structure 505 and the second limiting mating structure 4036 is reduced; this can be achieved by reducing the number of second limiting protrusions 506 located within the second limiting groove 4037. For example... Figure 15 and Figure 16 As shown, there are three second limiting protrusions 506. When the second air guide plate 20 is in the closed position, one second limiting protrusion 506 is located within the second limiting groove 4037; as shown... Figure 17 and Figure 18 As shown, when the second air guide plate 20 is in the open position, all three second limiting protrusions 506 are located within the second limiting groove 4037.

[0136] like Figure 6 As shown, the second limiting groove 4037 is arc-shaped and coincides with the movement trajectory of the second sub-connecting rod 403.

[0137] Optionally, such as Figure 6 As shown, the first limiting and fitting structure 4034 is located on the side of the second sub-connecting rod 403 away from the second gear 6022.

[0138] The second gear 6022 abuts against one side of the second sub-connecting rod body 4031, and the first limiting engagement structure 4034 abuts against the other side of the second sub-connecting rod body 4031. The second gear 6022, through meshing with the teeth on the second sub-connecting rod body 4031, provides a certain limiting effect on the second sub-connecting rod 403. The first limiting engagement structure 4034 is located on the side of the second sub-connecting rod body 4031 opposite to the second gear 6022, allowing both opposite sides of the second sub-connecting rod body 4031 to be limited, thereby stabilizing the position of the second sub-connecting rod body 4031 within the housing 50.

[0139] like Figure 6As shown, the second sub-connecting rod 403 protrudes outward from the side edge opposite to the second gear 6022 to form a first limiting protrusion 4035.

[0140] Optionally, such as Figure 7 As shown, the box body 50 includes a first side wall 507 and a second side wall 508, and a driving member 601 is disposed on the second side wall 508. The second side wall 508 is connected to the first side wall 507 and the connection point forms an angle; wherein, a first limiting structure 503 is disposed on the first side wall 507 and a second limiting structure 505 is disposed on the second side wall 508.

[0141] In the early stage of opening, the second air guide plate 20 mainly relies on the cooperation between the first limiting and cooperating structure 4034 and the first side wall 507 to limit and guide the second sub-connecting rod 403. In the later stage of opening, the second air guide plate 20 mainly relies on the cooperation between the second limiting and cooperating structure 4036 and the second side wall 508 to limit and guide the second sub-connecting rod 403.

[0142] The connection between the first sidewall 507 and the second sidewall 508 forms an angle, meaning that the first sidewall 507 and the second sidewall 508 are located on different planes. While achieving the limitation and guidance of the second sub-connecting rod 403, the size of a certain plane of the box body 50 can be reduced, thereby avoiding the box body 50 from being too large in a certain plane direction.

[0143] The first sidewall 507 includes a first wall segment 5071 and a second wall segment 5072. The second wall segment 5072 is connected to the first wall segment 5071 and is arranged sequentially along the direction of movement of the second sub-connecting rod 403 from the retracted position to the extended position; wherein, as shown... Figures 2 to 5 As shown, the first limiting structure 503 is provided on the first wall segment 5071, while the first limiting structure 503 is not provided on the second wall segment 5072.

[0144] During the opening of the second air guide plate 20, the second sub-connecting rod 403 moves along an arc. If the second wall section 5072 is also provided with a first limiting structure 503, then both the first wall section 5071 and the second wall section 5072 need to be arc-shaped structures, and the connection between the first wall section 5071 and the second wall section 5072 needs to be a smooth transition.

[0145] During the opening of the second air guide plate 20, the movement trajectory of the first sub-link 402 intersects with that of the second sub-link 403. When the second sub-link 403 moves toward a position closer to the first air guide plate 10, the first sub-link 402 moves toward a position away from the first air guide plate 10. If the second wall section 5072 is provided with a first limiting structure 503, it is inconvenient to provide a structure for limiting the first sub-link 402 on the box body 50.

[0146] Optionally, the first sub-link 402 is driven to connect with the second air guide plate 20 and moves between a retracted position inside the box 50 and an extended position outside the box 50.

[0147] like Figure 11 As shown, the box body 50 also includes a third side wall 509, which is disposed opposite to the second side wall 508. The limiting structure includes a third limiting structure 510 disposed on the third side wall 509. The first sub-link 402 is provided with a third limiting engagement structure 4023 to guide the first sub-link 402 to move between the retracted position and the extended position.

[0148] like Figure 10 and Figure 11 As shown, one of the third limiting structure 510 and the third limiting mating structure 4023 is a third limiting groove 511, and the other of the third limiting structure 510 and the third limiting mating structure 4023 is a third limiting mating protrusion 4024. The third limiting mating protrusion 4024 is located in the third limiting groove 511 and can move relative to the third limiting groove 511, so that the third limiting structure 510 has both a limiting function and a guiding function for the movement of the first sub-link 402 on the third limiting mating structure 4023, preventing the first sub-link 402 from deviating during its movement.

[0149] The third limiting groove 511 is arc-shaped and coincides with the movement trajectory of the first sub-connecting rod 402.

[0150] like Figure 11 As shown, the third sidewall 509 includes a third wall segment 5091 and a fourth wall segment 5092. The third wall segment 5091 corresponds to the first wall segment 5071; the fourth wall segment 5092 corresponds to the fourth wall segment 5092; wherein, the third wall segment 5091 and the fourth wall segment 5092 are respectively provided with a first sub-limiting structure 5101 and a second sub-limiting structure 5102, and the third limiting structure 510 includes the first sub-limiting structure 5101 and the second sub-limiting structure 5102.

[0151] A first sub-limiting structure 5101 and a second sub-limiting structure 5102 are respectively provided in the third wall section 5091 and the fourth wall section 5092, so that the third limiting structure 510 and the third limiting cooperation structure 4023 can be realized during the movement of the first sub-connecting rod 402.

[0152] like Figure 11 As shown, the first sub-limiting structure 5101 and the second sub-limiting structure 5102 are respectively the first sub-limiting groove and the second sub-limiting groove, and the first sub-limiting groove and the second sub-limiting groove are connected. The third limiting groove 511 includes the first sub-limiting groove and the second sub-limiting groove.

[0153] Optionally, along the direction in which the second sub-link 403 moves from the retracted position to the extended position, the fourth wall segment 5092 and the second wall segment 5072 extend toward the direction away from the center of the housing 50.

[0154] The fourth wall section 5092 extends away from the center of the box 50, so that the extension direction of the fourth wall section 5092 is the same as the movement direction of the second sub-connecting rod 403 during the opening of the second air guide plate 20. In this way, the second sub-limiting structure 5102 provided on the fourth wall section 5092 can cooperate with the third limiting and cooperating structure 4023.

[0155] Optionally, the first link 30, the first sub-link 402, and the second sub-link 403 are arranged sequentially along the direction from the third side wall 509 to the second side wall 508.

[0156] An embodiment of the second aspect of this application provides an air conditioner, including an indoor unit 100 and an outdoor unit connected to each other.
