[0057] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0058] Combination Figure 1-14 As shown, an embodiment of the present disclosure provides an air guide plate assembly for an indoor unit 100 , wherein the indoor unit 100 includes a shell having an air outlet 1001 , and the air guide plate assembly includes a guide plate 10 , an air guide plate 20 , a first connecting rod 30 , and a second connecting rod 40 .

[0059] The air guide plate 20 and the guide plate 10 are sequentially arranged along the width direction of the air outlet 1001 .

[0060] The air outlet 1001 includes a first air outlet area 1002 and a second air outlet area 1003, which are sequentially arranged along the width direction of the air outlet 1001. The guide plate 10 is arranged at the first air outlet area 1002, and is used to open or close the first air outlet area 1002, wherein, Fig.13 As shown, when the guide plate 10 opens the first air outlet area 1002, the guide plate 10 is in the open position, as shown in FIG. Figure 6 As shown, when the guide plate 10 covers the first air outlet area 1002, the guide plate 10 is in the closed position. The guide plate 20 is provided in the second air outlet area 1003, and is used to open or close the second air outlet area 1003, wherein, as shown in FIG. Fig.14 As shown, when the air guide plate 20 opens the second air outlet area 1003, the air guide plate 20 is in the open position, as shown in FIG. Figure 6 As shown, when the air guide plate 20 covers the second air outlet area 1003 , the air guide plate 20 is in a closed position.

[0061] The guide plate 10 and the air guide plate 20 are provided to control the first air outlet area 1002 and the second air outlet area 1003 respectively, so as to effectively change the air outlet area of ​​the air outlet 1001 and meet people's diverse air outlet needs.

[0062] The first connecting rod 30 is connected to the guide plate 10 for driving the guide plate 10 to move between an open position and a closed position; the second connecting rod 40 is connected to the air guide plate 20 for driving the air guide plate 20 to move between an open position and a closed position.

[0063] Among them, Fig.12 As shown, the motion trajectory of the second connecting rod 40 is arc-shaped, and the motion trajectory of the first connecting rod 30 is located inside the motion trajectory of the second connecting rod 40, wherein the side close to the center of the arc is the inner side, and the side away from the center of the arc is the outer side.

[0064] The movement trajectory of the first connecting rod 30 is located at the center side of the movement trajectory (arc) of the second connecting rod 40, so that the space occupied by the movement of the first connecting rod 30 is reduced, thereby making the space occupied by the entire air guide plate assembly small.

[0065] Optionally, the air guide plate assembly also includes a box body 50, and the first link 30 and the second link 40 move between an extended position extending out of the box body 50 and a retracted position retracted into the box body 50. The box body 50 is provided with a limiting structure, and the second link 40 is provided with a limiting matching structure. The limiting structure and the limiting matching structure cooperate with each other to guide the second link 40 to move between the extended position and the retracted position relative to the box body 50, so that the second link 40 moves between the extended position and the retracted position according to a preset motion trajectory to avoid displacement during the movement.

[0066] When the second connecting rod 40 is in the extended position, it drives the air guide plate 20 to move to the open position; when the second connecting rod 40 is in the retracted position, it drives the air guide plate 20 to move to the closed position.

[0067] When the guide plate 10 and the air guide plate 20 are both in the closed position, the first connecting rod 30 is located on the inner side of the limiting structure or the limiting matching structure.

[0068] When the guide plate 10 and the air guide plate 20 are both in the closed position, if the first connecting rod 30 is located on the outside of the limiting structure or the limiting matching structure, the space occupied by the first connecting rod 30 cannot be ignored when designing the entire air guide plate assembly, thereby increasing the space occupied by the entire air guide plate assembly.

[0069] When the guide plate 10 and the air guide plate 20 are both in the closed position, if the first connecting rod 30 intersects with the limiting structure or the limiting matching structure, the second connecting rod 40 will interfere with the first connecting rod 30 when moving along the limiting structure.

[0070] Therefore, when the guide plate 10 and the air guide plate 20 are both in the closed position, the first connecting rod 30 is located on the inner side of the limiting structure or the limiting matching structure, which can not only reduce the space occupied by the entire air guide plate assembly, but also avoid interference between the movement of the first connecting rod 30 and the second connecting rod 40.

[0071] Alternatively, if Fig.13 As shown, when the guide plate 10 is in the open position, one end of the guide plate 10 close to the air guide plate 20 in the closed position is located inside the other end of the guide plate 10; Fig.14 As shown, when the air guide plate 20 is in the open position, one end of the air guide plate 20 close to the guide plate 10 in the closed position is located on the inner side of the other end of the air guide plate 20, wherein the direction close to the middle of the indoor unit 100 is the inner side, and the direction away from the middle of the indoor unit 100 is the outer side.

[0072] Taking the guide plate 10 being located above the air guide plate 20 as an example, the end of the guide plate 10 close to the air guide plate 20 in the closed position is the lower end of the guide plate 10, and the other end of the guide plate 10 is the upper end; the end of the air guide plate 20 close to the guide plate 10 in the closed position is the upper end of the air guide plate 20, and the other end of the air guide plate 20 is the lower end.

[0073] When the guide plate 10 and the air guide plate 20 are both in the open position, they will be roughly in the shape of a figure eight. The guide plates can move synchronously or independently.

[0074] During cooling, the guide plate 10 is controlled to be opened to achieve upward air discharge; during heating, the guide plate 20 is controlled to be opened to achieve downward air discharge.

[0075] Alternatively, if Figure 6 and Fig.13As shown, when the guide plate 10 moves from the closed position to the open position, the movement trajectory of the first connecting rod 30 extends from the air guide plate 20 to the guide plate 10; Figure 6 and Fig.14 As shown, when the air guide plate 20 moves from the closed position to the open position, the movement trajectory of the second connecting rod 40 extends from the guide plate 10 to the air guide plate 20 .

[0076] During the opening process of the guide plate 10 and the air guide plate 20, the extension direction of the movement trajectory of the first connecting rod 30 and the second connecting rod 40 is such that the first connecting rod 30 and the second connecting rod 40 only need to occupy the space in the direction from the guide plate 10 to the air guide plate 20, and less space in the width direction of the indoor unit 100 is occupied, resulting in little structural change to the indoor unit 100.

[0077] Optionally, the first connecting rod 30 is fixedly connected to the guide plate 10, and the movement trajectory of the first connecting rod 30 includes an arc segment, which can simplify the connection method between the first connecting rod 30 and the guide plate 10 and avoid failure at the connection between the first connecting rod 30 and the guide plate 10, and can realize the closing and opening of the guide plate 10.

[0078] Optionally, the second connecting rod 40 includes a first sub-connecting rod 402 and a second sub-connecting rod 403 .

[0079] The first sub-connecting rod 402 is rotatably connected to the air guide plate 20; the second sub-connecting rod 403 is rotatably connected to the air guide plate 20; wherein, when the air guide plate 20 moves from a closed position to an open position, the movement trajectories of the first sub-connecting rod 402 and the second sub-connecting rod 403 are both arc-shaped.

[0080] The motion trajectory of the first sub-connecting rod 402 (eg Fig.11 The arc where the serial number 510 is located) and the motion trajectory of the second sub-connecting rod 403 (such as Figure 7 The arc where the serial number 507 is located) intersects. On the one hand, the space occupied by the movement of the first sub-link 402 and the second sub-link 403 can be reduced, and the space occupied by the entire air guide plate assembly can be further reduced. On the other hand, if the two do not intersect, it is necessary to set gears in the related technology to engage with the first sub-link 402 and the second sub-link 403 in sequence to achieve the predetermined trajectory of the air guide plate 20. In the present application, the first sub-link 402 and the second sub-link 403 can start to move at the same time during the opening process of the air guide plate 20, and there is no need to start one after another. Therefore, the intersection of the two can simplify the driving method of the first sub-link 402 and the second sub-link 403 when the first sub-link 402 is rotatably connected to the guide plate 10 and the second sub-link 403 is rotatably connected to the air guide plate 20, thereby simplifying the structure of the air guide plate assembly.

[0081] When the air guide plate 20 moves from the closed position to the open position, the movement trajectory of the first sub-connecting rod 402 and the movement trajectory of the second sub-connecting rod 403 both extend from the guide plate 10 to the air guide plate 20 .

[0082] Alternatively, if Figure 6 As shown, the rotation connection between the second sub-connecting rod 403 and the air guide plate 20 is located on the side of the rotation connection between the first sub-connecting rod 402 and the air guide plate 20 away from the guide plate 10 .

[0083] Taking the guide plate 10 being located above the air guide plate 20 as an example, the rotation connection between the second sub-connecting rod 403 and the air guide plate 20 is located below the rotation connection between the first sub-connecting rod 402 and the air guide plate 20 .

[0084] When the air deflector 20 moves from the closed position to the open position, at least one of the movement trajectories of the first sub-connecting rod 402 and the second sub-connecting rod 403 may also be a straight line or a non-arc-shaped curve.

[0085] During the opening process of the air guide plate 20, the first sub-connecting rod 402 and the second sub-connecting rod 403 move simultaneously, that is, they start moving at the same time and stop moving at the same time, rather than starting moving one after another, thereby shortening the time it takes for the air guide plate 20 to move to the target position and improving the response speed of the second air guide plate.

[0086] Alternatively, if Figure 6 As 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 arranged between the second sub-connecting rod body 4031 and the wind guide plate 20, and 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 wind guide plate 20.

[0087] The setting of the transmission rod 4032 makes the freedom of movement between the second sub-connecting rod body 4031 and the air guide plate 20 greater than the freedom of movement between the first sub-connecting rod 402 and the air guide plate 20. In this way, when the rotation connection between the second sub-connecting rod 403 and the air guide plate 20 is located on the side of the rotation connection between the first sub-connecting rod 402 and the air guide plate 20 away from the guide plate 10 and the movement trajectory of the first sub-connecting rod 402 and the movement trajectory of the second sub-connecting rod 403 intersect, the air guide plate 20 can be opened.

[0088] Alternatively, if Figure 6 As shown, when the 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 air guide plate 20; Fig.14As shown, when the air guide plate 20 is in the open position, the second sub-connecting rod 403 is located on the side of the first sub-connecting rod 402 facing the air guide plate 20, so that when the air guide plate 20 moves from the closed position to the open position, the movement trajectory of the first sub-connecting rod 402 intersects with the movement trajectory of the second sub-connecting rod 403.

[0089] Moreover, due to the existence of the transmission rod 4032, the second sub-connecting rod 403 and the air guide plate 20 have a large degree of freedom of movement, and the second sub-connecting rod 403 is more flexible in movement. Therefore, in the closed position of the air guide plate 20, the second sub-connecting rod 403 is far away from the air guide plate 20, and the first sub-connecting rod 402 moves close to the air guide plate 20. In this way, in the open position of the air guide plate 20, the second sub-connecting rod 403 can make a large angle of deflection with its flexible movement ability and move to a position closer to the air guide plate 20. The deflection ability of the first sub-connecting rod 402 is weaker than that of the second sub-connecting rod 403, and the first sub-connecting rod 402 moves to a position farther away from the air guide plate 20.

[0090] Optionally, during the process of the air guide plate 20 opening from the closed position to the open position, the movement speed of the first sub-connecting rod 402 is greater than the movement speed of the second sub-connecting rod, the radius of the circle where the movement trajectory (arc) of the first sub-connecting rod 402 is located is greater than the radius of the circle where the movement trajectory (arc) of the second sub-connecting rod is located, and the center angle corresponding to the movement trajectory of the first sub-connecting rod 402 is smaller than the center angle corresponding to the movement trajectory of the second sub-connecting rod.

[0091] like Figure 6 As shown, the first sub-connecting rod 402 includes a first sub-connecting rod body 4021 and a connecting rod 4022 .

[0092] The connecting rod 4022 is disposed between the first sub-connecting rod body 4021 and the air guide plate 20 , one end of the connecting rod 4022 is fixedly connected to the first sub-connecting rod body 4021 and a bend is formed at the connection, and the other end of the connecting rod 4022 is rotatably connected to the air guide plate 20 .

[0093] like Fig.12 As shown, the air guide plate 20 includes a first end 201 and a second end 202, and the first end 201 and the second end 202 are sequentially arranged along the width direction of the air outlet 1001. In the open position of the air guide plate 20, the second end 202 of the air guide plate 20 is located outside the first end 201, wherein the direction away from the center of the indoor unit 100 is the outside, and the direction close to the center of the indoor unit 100 is the inside.

[0094] When the air deflector 20 moves from the closed position to the open position, the movement trajectory of the first sub-connecting rod body 4021 is an arc. Due to the deflection angle of the second sub-connecting rod 403, the second sub-connecting rod 403 pushes the second end 202 of the air deflector 20 to move outward, and the air deflector 20 rotates around the rotation connection between the connecting rod 4022 and the air deflector 20 until it moves to the open position.

[0095] The connection between the first sub-connecting rod 402 and the air deflector 20 and the connection between the second sub-connecting rod 403 and the air deflector 20 are sequentially arranged along the direction from the first end 201 to the second end 202 .

[0096] The deflection ability of the second sub-connecting rod 403 is stronger than that of the first sub-connecting rod 402. Therefore, the rotation connection between the second sub-connecting rod 403 and the air guide plate 20 is arranged close to the second end 202, and the rotation connection between the first sub-connecting rod 402 and the air guide plate 20 is arranged close to the first end 201. In other words, the rotation connection between the first sub-connecting rod 402 and the air guide plate 20 and the rotation connection between the transmission rod 4032 and the air guide plate 20 are arranged in sequence along the direction from the first end 201 to the second end 202.

[0097] Optionally, the air guide plate assembly further includes a driving device 60 .

[0098] The driving device 60 is drivingly connected to the first sub-connecting rod 402 and the second sub-connecting rod 403, and is used to drive the first sub-connecting rod 402 and the second sub-connecting rod 403 to perform differential movement, and the movement speed of the first sub-connecting rod 402 is greater than the movement speed of the second sub-connecting rod 403, so that when the air guide plate 20 moves to the open position, the first end 201 is located on the inner side of the second end 202.

[0099] Alternatively, if Fig.12 As shown, the driving device 60 includes a driving gear 603. Figure 8 and Fig. 9 As shown, the first connecting rod 30 is provided with a first gear tooth portion 302 and a second gear tooth portion 303. Along the movement direction of the first connecting rod 30 during the opening process of the guide plate 10 (the process of moving from the closed position to the open position), the second gear tooth portion 303 and the first gear tooth portion 302 are arranged in sequence. The first gear tooth portion 302 is a straight gear tooth extending along the length direction of the first connecting rod 30, and the second gear tooth portion 303 is an arc gear tooth extending along the length direction of the first connecting rod 30. During the opening process of the guide plate 10 of the driving gear 603, the driving gear 603 successively meshes with the first gear tooth portion 302 and the second gear tooth portion 303.

[0100] During the opening process of the guide plate 10, the driving gear 603 first meshes with the first gear portion 302. Since the first gear portion 302 is a linear gear, when the driving gear 603 meshes with the first gear portion 302, the guide plate 10 can be driven to move in a straight line. When the guide plate 10 is in the closed position, there is a non-zero angle between the straight line where the first gear portion 302 is located and the guide plate 10, for example, the angle is 90° or close to 90°, so that when the driving gear 603 meshes with the first gear portion 302, the guide plate 10 extends outward, wherein the direction close to the center of the indoor unit 100 is the inner direction, and the direction away from the center of the indoor unit 100 is the outer direction. The guide plate 10 first extends outward, which can avoid interference with other parts of the indoor unit 100 caused by direct rotation during the opening process of the guide plate 10.

[0101] After the driving gear 603 is disengaged from the first gear tooth portion 302, it meshes with the second gear tooth portion 303. Since the second gear tooth portion 303 is an arc-shaped gear tooth extending along the length direction of the first connecting rod 30, when the driving gear 603 meshes with the second gear tooth portion 303, it can drive the first connecting rod 30 to make an arc motion, thereby driving the air guide plate to rotate.

[0102] The air deflector assembly further includes a driving element 604, which may be a motor, and is used to be drivingly connected to the driving gear 603 to drive the driving gear 603 to rotate. The rotation of the driving gear 603 drives the first connecting rod 30 to move.

[0103] Optionally, the first gear tooth portion 302 is perpendicular to the guide plate 10 in the closed position.

[0104] The guide plate 10 is a curved surface, but after the guide plate 10 is infinitely divided, each small piece can be regarded as a plane. A connecting column 101 is provided on one of the small pieces, and the connecting column 101 is rotatably connected to the first sub-connecting rod 402. The first gear portion 302 is perpendicular to the guide plate 10 in the closed position, which means that the first gear portion 302 is perpendicular to the plane where the small piece on the guide plate 10 where the connecting column 101 is located. In this way, when the driving gear 603 is engaged with the first gear portion 302, the guide plate 10 is pushed out along the axis of the air duct to avoid the deviation of the guide plate 10 and the interference of the guide plate 10 with other parts of the indoor unit 100.

[0105] Optionally, the length of the first gear tooth portion 302 is smaller than the length of the second gear tooth portion 303 .

[0106] When the guide plate 10 is pushed out a short distance during the opening process, the guide plate 10 can be prevented from interfering with other parts of the indoor unit 100 . Therefore, the length of the first gear tooth portion 302 is smaller than the length of the second gear tooth portion 303 .

[0107] Optionally, the first connecting rod 30 is fixedly connected to the guide plate 10 .

[0108] By setting the shape, position and movement trajectory of the first connecting rod 30, the first connecting rod 30 can be fixedly connected to the guide plate 10. Compared with the first connecting rod 30 being movably connected to the guide plate 10 (for example, rotatingly connected), the fixed connection can simplify the connection structure between the first connecting rod 30 and the guide plate 10 and enhance the reliability of the movement of the guide plate 10.

[0109] Optionally, the driving gear 603 is located in the box body 50 , and the first connecting rod 30 moves between an extended position extending out of the box body 50 and a retracted position retracting into the box body 50 .

[0110] When the first link 30 is in the retracted position, the guide plate 10 is in the closed position. When the first link 30 is in the extended position, the guide plate 10 is in the open position.

[0111] like Fig. 9 and Fig.11 As shown, the box body 50 is provided with a guide mechanism 502, and the first connecting rod 30 is provided with a guide matching mechanism 304. The guide mechanism 502 cooperates with the guide matching mechanism 304 to guide the first connecting rod 30 to move between the extended position and the retracted position to avoid deviation of the first connecting rod 30 during movement.

[0112] One of the guide mechanism 502 and the guide matching mechanism 304 is a guide column, and the other is a guide groove. The guide column 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.

[0113] The guide groove includes a first sub-guide groove 5021 and a second sub-guide groove 5022. During the opening of the 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 linear, and the second sub-guide groove is arc-shaped. When the guide column is located in the first guide groove and cooperates with the first guide groove, the driving gear cooperates with the first gear tooth portion, the first connecting rod moves linearly, and the first guide plate is pushed outward; when the guide column is located in the second guide groove and cooperates with the second guide groove, the driving gear cooperates with the second gear tooth portion, the first connecting rod moves in an arc shape, and the first guide plate starts to rotate.

[0114] Optionally, one end of the first connecting rod 30 is connected to the guide plate 10 , and the other end of the first connecting rod 30 extends in a direction from the guide plate 10 to the air guide plate 20 .

[0115] This arrangement enables the driving gear 603 to drive the guide plate 10 to be in the open position when it is meshed with the first connecting rod 30 , and the end of the guide plate 10 close to the air guide plate 20 in the closed position is located inside the other end of the guide plate 10 .

[0116] The driving device 60 includes a driving mechanism that is drivingly connected to the second connecting rod 40 and is used to drive the second connecting rod 40 to move, so as to drive the air guide plate 20 to move between the open position and the closed position.

[0117] like Figure 6 As shown, the driving mechanism is disposed between the first connecting rod 30 and the second connecting rod 40 .

[0118] The driving mechanism includes a driving member 601 and a gear set 602 , and the second connecting rod 40 is provided with gear teeth.

[0119] The gear set 602 is connected to the driving member 601 and meshes with the gear teeth. The driving 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 to realize the opening and closing of the air guide plate 20; wherein, the axis of the gear set 602 is located between the first connecting rod 30 and the second connecting rod 40, so that the air guide plate assembly has a compact structure and occupies a small space.

[0120] The driving member 601 may be a motor.

[0121] like Figure 8 As shown, the first connecting rod 30 is provided with an avoidance groove 301 for avoiding the gear set 602 to avoid interference between the first connecting rod 30 and the gear set 602 .

[0122] 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 .

[0123] The first gear 6021 meshes with the gear teeth of the first sub-connecting rod 402; the second gear 6022 meshes with the gear 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 air guide plate 20 to move between the open position and the closed position, wherein the first gear 6021 and the second gear 6022 are coaxially connected, and the radii of the two are not equal.

[0124] like Figure 6 As shown, the first gear 6021 and the second gear 6022 are coaxially arranged, so that the angular velocity of the first gear 6021 and the second gear 6022 are the same, but the radius of the first gear 6021 and the second gear 6022 are not equal, so that the movement speeds of the first sub-connecting rod 402 and the second sub-connecting rod 403 are different, thereby driving the air guide plate 20 to rotate to the open position.

[0125] The radius of the first gear 6021 is greater than the radius of the second gear 6022 , so that the movement speed of the first sub-connecting rod 402 is greater than the movement speed of the second sub-connecting rod 403 .

[0126] Since the first sub-connecting rod 402 and the second sub-connecting rod 403 move simultaneously, during the opening process of the air guide plate 20 , the movement stroke of the first sub-connecting rod 402 is greater than the movement stroke of the second sub-connecting rod 403 .

[0127] Optionally, the transmission rod 4032 is provided with an avoidance groove 4033 , and when the air deflector 20 is in the open position, the connection between the first sub-connecting rod 402 and the air deflector 20 is located in the avoidance groove 4033 .

[0128] like Fig.14 As shown, when the air deflector 20 is in the open position, 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 air deflector 20 from affecting the movement of the transmission rod 4032.

[0129] Optionally, the second sub-connecting rod 403 moves between a retracted position in the box body 50 and an extended position extending out of the box body 50 to drive the air guide plate 20 to move between an open position and a closed position; Figure 7 As shown, the limiting structure includes a first limiting structure 503 and a second limiting structure 505 provided on the box body 50. Figure 6 As shown, the limiting matching structure includes a first limiting matching structure 4034 matched with the first limiting structure 503 and a second limiting matching structure 4036 matched with the second limiting structure 505, so as to guide the second sub-connecting rod 403 to move between the retracted position and the extended position.

[0130] When the air guide plate 20 is opened, the matching area between the first position limiting structure 503 and the first position limiting matching structure 4034 is reduced, and the matching area between the second position limiting structure 505 and the second position limiting matching structure 4036 is increased.

[0131] During the opening process of the air guide plate 20, the matching area between the first limiting structure 503 and the first limiting matching structure 4034 is reduced, and the matching area between the second limiting structure 505 and the second limiting matching structure 4036 is increased. In other words, during the opening process of the air guide plate 20, the first limiting structure 503 has a tendency to gradually release the matching with the first limiting matching, and the second limiting structure 505 and the second limiting matching structure 4036 gradually deepen the matching. Compared with the situation that the first limiting structure 503 and the first limiting matching structure 4034 are in the whole process and the matching area size remains unchanged, and the second limiting structure 505 and the second limiting matching structure 4036 are in the whole process and the matching area size remains unchanged during the opening process of the air guide plate 20, the present 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.

[0132] One of the first limiting structure 503 and the first limiting matching structure 4034 is the first limiting groove 504, and the other of the first limiting structure 503 and the first limiting matching structure 4034 is the 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 effect on the first limiting matching structure 4034 and a function of guiding the movement of the second sub-connecting rod 403 to prevent the second sub-connecting rod 403 from offset during movement.

[0133] The number of the first limiting protrusion 4035 can be one or more. Figure 3 and Figure 6 As shown, when there is one first limiting protrusion 4035, the matching area between the first limiting structure 503 and the first limiting matching structure 4034 is reduced, which may be a reduction in the portion of the first limiting protrusion 4035 located in the first limiting groove 504. When there are multiple first limiting protrusions 4035, the matching area between the first limiting structure 503 and the first limiting matching structure 4034 is reduced, which may be a reduction in the number of the multiple first limiting protrusions 4035 located in the first limiting groove 504.

[0134] The first limiting groove 504 is arc-shaped and coincides with the movement trajectory of the second sub-connecting rod 403 .

[0135] One of the second limiting structure 505 and the second limiting matching structure 4036 is a second limiting groove 4037, and the other of the second limiting structure 505 and the second limiting matching 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 effect on the second limiting matching structure 4036 and a function of guiding the movement of the second sub-connecting rod 403 to prevent the second sub-connecting rod 403 from offset during movement.

[0136] The number of the second limiting protrusions 506 may be one or more. When the number of the second limiting protrusions 506 is one, the matching area between the second limiting structure 505 and the second limiting matching structure 4036 is reduced, which may be the case that the portion of the second limiting protrusion 506 located in the second limiting groove 4037 is reduced. When the number of the second limiting protrusions 506 is more than one, the matching area between the second limiting structure 505 and the second limiting matching structure 4036 is reduced, which may be the case that the number of the second limiting protrusions 506 located in the second limiting groove 4037 among the multiple second limiting protrusions 506 is reduced. Fig.15 and Fig.16As shown, the number of the second limiting protrusions 506 is three. When the air guide plate 20 is in the closed position, one second limiting protrusion 506 is located in the second limiting groove 4037; Fig.17 and Fig.18 As shown, when the air guide plate 20 is in the open position, the three second limiting protrusions 506 are all located in the second limiting grooves 4037 .

[0137] 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 .

[0138] Alternatively, if Figure 6 As shown, the first position limiting matching structure 4034 is located on a side of the second sub-connecting rod 403 away from the second gear 6022 .

[0139] The second gear 6022 is in contact with one side of the second sub-connecting rod body 4031, and the first position-limiting matching structure 4034 is in contact with the other side of the second sub-connecting rod body 4031. The second gear 6022 has a certain position-limiting effect on the second sub-connecting rod 403 by meshing with the gear teeth on the second sub-connecting rod body 4031. The first position-limiting matching structure 4034 is provided on the side of the second sub-connecting rod body 4031 away from the second gear 6022, so that both opposite sides of the second sub-connecting rod body 4031 can be limited, thereby achieving the stability of the position of the second sub-connecting rod body 4031 in the box body 50.

[0140] like Figure 6 As shown, the edge of one side of the second connecting rod 403 away from the second gear 6022 protrudes outward to form a first limiting protrusion 4035 .

[0141] Alternatively, if Figure 7 As shown, the box body 50 includes a first side wall 507 and a second side wall 508, and the 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 a fold is formed at the connection; wherein, the first limiting structure 503 is disposed on the first side wall 507, and the second limiting structure 505 is disposed on the second side wall 508.

[0142] In the early stage of opening the air guide plate 20, the first position-limiting matching structure 4034 cooperates with the first side wall 507 to limit and guide the second sub-connecting rod 403. In the later stage of opening the air guide plate 20, the second position-limiting matching structure 4036 cooperates with the second side wall 508 to limit and guide the second sub-connecting rod 403.

[0143] The connection between the first side wall 507 and the second side wall 508 forms an angle, that is, the first side wall 507 and the second side wall 508 are located in different planes. When the second sub-connecting rod 403 is limited and guided, the size of the box body 50 on a certain plane can be reduced, thereby avoiding the box body 50 from being too large in a certain plane direction.

[0144] The first side wall 507 includes a first wall section 5071 and a second wall section 5072. The second wall section 5072 is connected to the first wall section 5071 and is sequentially arranged along the direction in which the second sub-connecting rod 403 moves from the retracted position to the extended position; Figures 2 to 5 As shown, the first limiting structure 503 is disposed on the first wall segment 5071 , and the first limiting structure 503 is not disposed on the second wall segment 5072 .

[0145] During the opening of the air guide plate 20, the second connecting rod 403 moves along an arc. If the second wall segment 5072 is also provided with the first limiting structure 503, the first wall segment 5071 and the second wall segment 5072 need to be arc structures, and the connection between the first wall segment 5071 and the second wall segment 5072 needs to be a smooth transition.

[0146] During the opening process of the air guide plate 20, the movement trajectory of the first sub-connecting rod 402 intersects with the movement trajectory of the second sub-connecting rod 403. When the second sub-connecting rod 403 moves toward a position close to the guide plate 10, the first sub-connecting rod 402 moves toward a position away from the guide plate 10. If the second wall segment 5072 is provided with the first limiting structure 503, it is inconvenient to provide a structure for limiting the first sub-connecting rod 402 on the box body 50.

[0147] Optionally, the first sub-connecting rod 402 is drivingly connected to the air guide plate 20 , and moves between a retracted position located in the box body 50 and an extended position extending out of the box body 50 .

[0148] like Fig.11 As shown, the box body 50 also includes a third side wall 509, which is arranged opposite to the second side wall 508. The limiting structure includes a third limiting structure 510 arranged on the third side wall 509, and the first sub-connecting rod 402 is provided with a third limiting matching structure 4023 to guide the first sub-connecting rod 402 to move between the retracted position and the extended position.

[0149] like Fig.10 and Fig.11As shown, one of the third limiting structure 510 and the third limiting matching structure 4023 is the third limiting groove 511, and the other of the third limiting structure 510 and the third limiting matching structure 4023 is the third limiting matching protrusion 4024. The third limiting matching 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 effect on the third limiting matching structure 4023 and a function of guiding the movement of the first sub-connecting rod 402 to prevent the first sub-connecting rod 402 from offset during the movement.

[0150] The third limiting groove 511 is arc-shaped and coincides with the movement trajectory of the first sub-connecting rod 402 .

[0151] like Fig.11 As shown, the third side wall 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 limit structure 510 includes a first sub-limiting structure 5101 and a second sub-limiting structure 5102.

[0152] The first sub-limiting structure 5101 and the second sub-limiting structure 5102 are respectively arranged on the third wall segment 5091 and the fourth wall segment 5092 , so that the third limit structure 510 can cooperate with the third limit matching structure 4023 during the movement of the first sub-connecting rod 402 .

[0153] like Fig.11 As shown, the first sub-limiting structure 5101 and the second sub-limiting structure 5102 are respectively the first sub-limiting slot and the second sub-limiting slot, and the first sub-limiting slot and the second sub-limiting slot are connected. Among them, the third limit slot 511 includes the first sub-limiting slot and the second sub-limiting slot.

[0154] Optionally, along the direction in which the second sub-connecting rod 403 moves from the retracted position to the extended position, the fourth wall segment 5092 and the second wall segment 5072 extend in a direction away from the middle of the box body 50 .

[0155] The fourth wall segment 5092 extends in a direction away from the middle of the box body 50, so that the extension direction of the fourth wall segment 5092 is the same as the movement direction of the second sub-connecting rod 403 during the opening process of the air guide plate 20. In this way, the second sub-limiting structure 5102 provided on the fourth wall segment 5092 can cooperate with the third limiting matching structure 4023.

[0156] Optionally, the first connecting rod 30 , the first sub-connecting rod 402 and the second sub-connecting rod 403 are sequentially arranged along the direction from the third side wall 509 to the second side wall 508 .

[0157] An embodiment of a second aspect of the present application provides an air conditioner, comprising an indoor unit 100 and an outdoor unit connected to each other.

[0158] The indoor unit 100 includes a shell and an air guide plate assembly for the indoor unit 100 as described in any of the above embodiments, the shell is provided with an air outlet 1001, and the guide plate 10 and the air guide plate 20 are arranged at the air outlet 1001 and arranged in sequence along the width direction of the air outlet 1001.
