[0079] Combine Figure 1-46 As shown, an embodiment of the present disclosure provides a driving device.

[0080] The air conditioner includes an indoor unit 100 and an outdoor unit connected to the indoor unit. The indoor unit 100 includes a housing 1001, an evaporator, a fan, and an air guide plate 1002. The housing 1001 defines an air duct, within which the evaporator and fan are located. The housing 1001 is provided with an air inlet and an air outlet connected to the air duct, and the air guide plate 1002 is located at the air outlet. The fan drives air into the air duct through the air inlet, where it exchanges heat with the evaporator before being blown out of the air outlet. The air guide plate 1002 is used to adjust the airflow direction of the air outlet. Specifically, when the air guide plate 1002 is in different airflow guiding positions, the airflow direction of the air outlet varies.

[0081] The driving device includes a connecting rod assembly and a rotating member 3 . The connecting rod assembly includes a connecting rod. The connecting rod includes a first connecting rod 1 and / or a second connecting rod 2 .

[0082] The first connecting rod 1 is configured to be rotatably connected to the wind deflector 1002; the second connecting rod 2 is configured to be rotatably connected to the wind deflector 1002; the rotating member 3 includes a first driving portion rotatably connected to the first connecting rod 1, and a second driving portion rotatably connected to the second connecting rod 2.

[0083] When the rotating member 3 rotates in a set direction, the first connecting rod 1 is driven to move by the first driving part and the second connecting rod 2 is driven to move by the second driving part, so that the air guide plate 1002 is opened.

[0084] When the rotating member 3 rotates in the opposite direction of the set direction, the first driving part drives the first connecting rod 1 to move, and the second driving part drives the second connecting rod 2 to move, so as to close the air guide plate 1002. The set direction can be clockwise or counterclockwise.

[0085] The first connecting rod includes a first rod body 18 and a connecting portion 192 . The connecting portion is rotatably connected to the wind deflector and is provided at one end of the first rod body.

[0086] During the opening process of the wind deflector 1002, the motion trajectory of the first connecting rod 1 includes a first curved segment trajectory 513, and the center of curvature of the first curved segment trajectory is a non-fixed point; and / or, the motion trajectory of the second connecting rod 2 includes a second curved segment trajectory, and the center of curvature of the second curved segment trajectory is a non-fixed point.

[0087] During the opening process of the wind deflector 1002, the movement trajectory of the first rod body 18 includes a first curved segment trajectory 513, and the curvature radius of at least two points on the first curved segment trajectory is different, and / or the movement trajectory of the second connecting rod 2 includes a second curved segment trajectory, and the curvature radius of at least two points on the second curved segment trajectory is different.

[0088] like Figure 4 and Figure 27As shown, the center of curvature of the first curved segment trajectory is non-fixed, and the centers of curvature of at least two points on the first curved segment trajectory are not the same point. Thus, the first curved segment trajectory is non-circular, so that during the opening process of the air deflector 1002, the first rod body 18 undergoes both a first extension motion (approximately in a direction perpendicular to the plane where the air outlet is located) extending out of the air outlet, and a movement deviating from the first extension direction (the direction of the first extension motion) along a first deviating motion direction. The first deviating motion direction and the first extension motion direction form a non-zero angle. For example, the first deviating motion direction is approximately along the width direction of the first rod body, and the movements in the first deviating motion direction and the first extension motion direction are both located within the plane where the first rod body 1 is located. The first deviating motion direction and the first extension motion direction together form the first motion of the first rod body 1.

[0089] The center of curvature of the second curved segment trajectory is a non-fixed point, and the centers of curvature of at least two points on the second curved segment trajectory are not the same point. Thus, the second curved segment trajectory is non-circular, so that during the opening process of the air deflector 1002, the second connecting rod 2 has both a second extension movement extending out of the air outlet (roughly in a direction perpendicular to the plane where the air outlet is located), and a movement deviating from the second extension movement direction (the direction of the second extension movement) and along a second deviating movement direction. The second deviating movement direction and the second extension movement direction have a non-zero angle. For example, the second deviating movement direction is roughly along the width direction of the second connecting rod, and the movements in the second deviating movement direction and the second extension movement direction are both located within the plane where the second connecting rod 2 is located. The second deviating movement direction and the second extension movement direction together synthesize the second movement of the second connecting rod 2.

[0090] During the opening process of the wind deflector 1002, the movement trajectory of the first rod body 18 includes the first curved segment trajectory and / or the movement trajectory of the second connecting rod 2 includes the second curved segment trajectory, so that the first rod body and the connecting part can be made into an integrated structure and directly rotatably connected to the wind deflector 1002 through the first rotating shaft, without the need to additionally set up a crank in the related technology, thereby avoiding interference between the wind deflector 1002 and the shell 1001 during the opening process of the wind deflector 1002. The second connecting rod 2 can also be made into an integrated structure and directly rotatably connected to the wind deflector 1002 through the second rotating shaft, without the need to additionally set up a crank in the related technology, thereby avoiding interference between the wind deflector 1002 and the shell 1001 during the opening process of the wind deflector 1002.

[0091] Optionally, the first rod body and the connecting portion are an integral structure and are directly rotationally connected to the wind deflector 1002 via a first rotation axis; and / or, the second connecting rod 2 is an integral structure and is directly rotationally connected to the wind deflector 1002 via a second rotation axis.

[0092] Alternatively, as Figure 4As shown, in the process of the air deflector 1002 opening from the first position to the second position, the motion trajectory of the first rod body 18 includes a first sub-curve segment trajectory 514 and a second sub-curve segment trajectory 515 connected to each other, the curvature center of the first sub-curve segment trajectory is located on the side of the first sub-curve segment trajectory facing the air outlet, and the curvature center of the second sub-curve segment trajectory is located on the side of the second sub-curve segment trajectory away from the air outlet. The motion trajectory of the second connecting rod 2 is a straight line trajectory N, as shown in FIG. Figure 28 shown.

[0093] Among them, the first curve segment trajectory includes a first sub-curve segment trajectory and a second sub-curve segment trajectory. During the process of the air guide plate 1002 opening from the first position to the second position, the first connecting rod 1 passes through the first sub-curve segment trajectory and the second sub-curve segment trajectory in sequence.

[0094] The center of curvature of the first sub-curve segment trajectory is located on the side of the first sub-curve segment trajectory facing the air outlet 1003, and the center of curvature of the second sub-curve segment trajectory is located on the side of the second sub-curve segment trajectory away from the air outlet, that is, the bending directions of the first sub-curve segment trajectory and the second sub-curve segment trajectory are different, thereby realizing that the first connecting rod 1 has a first deviating motion direction in addition to the movement in the first extending motion direction.

[0095] The trajectory of the first sub-curve segment is not parallel to the length direction of the first connecting rod and the center of curvature of the first sub-curve segment trajectory is a non-fixed point, that is, the centers of curvature of at least two segments on the first sub-curve segment trajectory are different; the trajectory of the second sub-curve segment is not parallel to the length direction of the first connecting rod and the center of curvature of the second sub-curve segment trajectory is a non-fixed point, that is, the centers of curvature of at least two segments on the second sub-curve segment trajectory are different.

[0096] With this arrangement, when the first rod body 18 moves along the first sub-curved segment trajectory, the first connecting rod 1 moves in the first extension motion direction and in the first sub-motion direction. When the first connecting rod 1 moves along the second sub-curved segment trajectory, the first connecting rod 1 moves in the first extension motion direction and in the second sub-motion direction. The first deviating motion direction includes the first sub-motion direction and the second sub-motion direction, and the first sub-motion direction and the second sub-motion direction are different directions, that is, they have different angles with the first extension motion direction.

[0097] Optionally, during the process of the air guide plate 1002 opening from the second position to the fourth position, the movable connection between the second link 2 and the air guide plate 1002 rotates around the first rotation axis. Taking the movable connection between the second link 2 and the air guide plate 1002 as an example, the axis of the second rotation axis rotates around the axis of the first rotation axis.

[0098] During the process of the air guide plate 1002 opening from the second position to the fourth position, the first connecting rod 1 stops moving. Figure 28As shown, the motion trajectory of the second connecting rod 2 is an arc trajectory M.

[0099] In this arrangement, the first connecting rod 1 stops moving, which can simplify the structure of the driving device and reduce the cost of the driving device while realizing the opening of the air guide plate 1002 from the second position to the fourth position.

[0100] The arc-shaped trajectory M is connected to the straight-line trajectory N and is located on one side of the straight-line trajectory, and the center of the arc-shaped trajectory M is located on the side of the arc-shaped trajectory M away from the air outlet.

[0101] Optionally, the first driving portion includes a first active portion, the second driving portion includes a second active portion, and the number of the first active portion and / or the second active portion is multiple. The first connecting rod 1 includes a first driven portion adapted to the first active portion, the first driven portion being disposed on the first rod body; the second connecting rod 2 includes a second driven portion adapted to the second active portion.

[0102] The first connecting rod 1 includes a first driving structure drivingly connected to the first driving portion, and the first driving structure is the first driven portion. The first driving structure includes a first groove structure, and the first driving portion includes a first protrusion structure disposed within the first groove structure and capable of sliding relative to the first groove structure. In this case, the first protrusion structure includes a first active portion, and the number of first active portions is multiple. Alternatively, the first driving portion includes a first groove structure, and the first driving structure includes a first protrusion structure disposed within the first groove structure and capable of sliding relative to the first groove structure. In this case, the first groove structure includes a first active portion, and the number of first active portions is multiple.

[0103] The second connecting rod 2 includes a second driving structure drivingly connected to the second driving portion, which is the second driven portion. The second driving structure includes a second groove structure, and the second driving portion includes a second protrusion structure disposed within the second groove structure and capable of sliding relative to the second groove structure. In this case, the second protrusion structure includes a second active portion, and the number of second active portions is multiple. Alternatively, the second driving portion includes a second groove structure, and the second driving structure includes a second protrusion structure disposed within the second groove structure and capable of sliding relative to the second groove structure. In this case, the second groove structure includes a second active portion, and the number of second active portions is multiple.

[0104] Through the cooperation of the first groove structure and the first protrusion structure, the first driving part can drive the first connecting rod 1 to move, and through the cooperation of the second groove structure and the second protrusion structure, the second driving part can drive the second connecting rod 2 to move, thereby realizing the opening and closing of the air guide plate 1002.

[0105] In the first position, the driving point of the rotating part on the first connecting rod (the matching point of the first groove structure and the first protrusion structure) does not coincide with the movement direction of the air guide plate, and the driving point of the rotating part on the second connecting rod (the matching point of the second groove structure and the second protrusion structure) does not coincide with the movement direction of the air guide plate, avoiding coincidence with the movement direction to form a dead point position, so that the air guide plate cannot be manually opened when the air conditioner is powered off.

[0106] Optionally, there are multiple first active parts, including a first sub-active part and a second sub-active part, and there are multiple second active parts, including a third sub-active part. One of the first sub-active part and the first driven part includes a first boss 31, and the other includes a first drive slot 11, i.e., the first boss 31 is provided on the rotating member 3 and the first drive slot 11 is provided on the first connecting rod 1, or the first drive slot 11 is provided on the rotating member 3 and the first boss 31 is provided on the first connecting rod 1. One of the second sub-active part and the first driven part includes a second boss 32, and the other includes a second drive slot 12.

[0107] The first groove structure includes a first driving groove 11 and a second driving groove 12; the first protrusion structure includes a first protrusion 31 and a second protrusion 32; when the air deflector 1002 opens from the first position to the second position, the first protrusion 31 is arranged in the first driving groove 11 and can slide relative to the first driving groove 11, and the second protrusion 32 is arranged in the second driving groove 12 and can slide relative to the second driving groove 12; wherein, Figure 7 and Figure 30 As shown, the first driving groove 11 and / or the second driving groove 12 are curved grooves.

[0108] When the first driving groove 11 and the second driving groove 12 coexist, at least one of the first driving groove 11 and the second driving groove 12 is a curved groove, so that the motion trajectory of the first rod body includes a first curved segment trajectory.

[0109] like Figure 11 As shown, the drive device includes a power source, which includes a driving member 7, a transmission member, and a transmission shaft 4. The transmission shaft 4 is disposed between the driving member 7 and the transmission member, so that the driving member 7 drives the transmission member to move via the transmission shaft 4. The transmission member is the aforementioned rotating member 3. The driving member 7 includes a motor, which is connected to the rotating member 3 via the transmission shaft 4 to drive the rotating member 3 to rotate.

[0110] like Figure 21 、 Figure 22 、 Figure 32 As shown, the transmission shaft 4 is provided with a first limiting portion 401, and the transmission member is provided with a first limiting matching portion 301 that matches the first limiting portion 401 to limit the movement of the transmission member relative to the transmission shaft 4 along the first limiting direction; Figure 31As shown, the transmission shaft 4 is provided with a second limiting portion 402, and the transmission member is provided with a second limiting matching portion 302 matching with the second limiting portion 402 to limit the movement of the transmission member relative to the transmission shaft 4 along the second limiting direction. The first limiting direction is the movement direction (rotation direction) of the transmission member, and the second limiting direction is perpendicular to the first limiting direction.

[0111] The first limiting portion 401 cooperates with the first limiting matching portion 301 to limit the transmission member in the first limiting direction, that is, to limit the transmission member in the direction of movement, thereby achieving relative stillness between the transmission member and the transmission shaft 4 in the direction of movement of the transmission member, allowing the transmission shaft 4 to drive the transmission member in the direction of movement of the transmission member, that is, the transmission member can move with the transmission shaft 4. The second limiting portion 402 cooperates with the second limiting matching portion 302 to limit the transmission member in the second limiting direction, thereby cooperating with the first limiting portion 401 and the first limiting matching portion 301 to limit the transmission member in multiple directions, allowing the transmission member to achieve the desired movement effect.

[0112] Optionally, the first limiting portion 401 and the second limiting portion 402 are sequentially arranged along the circumference of the transmission shaft 4 , so that the circumferential space of the transmission shaft 4 can be reasonably utilized, making the structure of the transmission shaft 4 more compact.

[0113] There are multiple first limiting parts 401 and multiple second limiting parts 402, and the multiple first limiting parts 401 and the multiple second limiting parts 402 are arranged in sequence along the circumference of the transmission shaft 4, and the first limiting parts 401 and the second limiting parts 402 are arranged at intervals, so that the transmission shaft 4 is evenly stressed.

[0114] Alternatively, as Figure 21 、 Figure 22 、 Figure 32 As shown, one of the first limiting portion 401 and the first limiting matching portion 301 is a first limiting protrusion 4011 , and the other is a limiting groove 3011 matched with the first limiting protrusion 4011 , and the first limiting protrusion 4011 is limited in the limiting groove 3011 .

[0115] The first limiting portion 401 is a first limiting protrusion 4011, and the first limiting matching portion 301 is a limiting groove 3011. Alternatively, the first limiting portion 401 is a limiting groove 3011, and the first limiting matching portion 301 is a first limiting protrusion 4011. The first limiting protrusion 4011 is matched with the limiting groove 3011, and the first limiting protrusion 4011 is limited in the limiting groove 3011. In this way, the transmission member can be limited in the direction of movement (i.e., the first limiting direction), and can also be limited in the direction opposite to the direction of movement. For example, when the transmission shaft 4 rotates clockwise, the first limiting direction is the clockwise direction.

[0116] Alternatively, as Figure 21 、 Figure 22and Figure 32 As shown, the transmission shaft 4 is provided with a third limiting portion 403, and the transmission member is provided with a third limiting matching portion 304 matching with the third limiting portion 403 to limit the movement of the transmission member relative to the transmission shaft 4 in a direction opposite to the second limiting direction, thereby making the position of the transmission member more stable.

[0117] Alternatively, as Figure 32 As shown, when the first limiting portion 401 is the first limiting protrusion 4011, the third limiting matching portion 304 is a limiting rib 3041 provided on the inner wall surface of the limiting groove 3011, and the third limiting portion 403 is the surface of the first limiting protrusion 4011 facing the limiting rib 3041 and abutting against the limiting rib 3041. The limiting rib 3041 and the third limiting portion 403 are arranged in sequence along a direction opposite to the second limiting direction to limit the movement of the transmission member relative to the transmission shaft 4 along a direction opposite to the second limiting direction. Alternatively, when the first limiting portion 401 is a limiting groove 3011, the third limiting portion 403 is a limiting rib 3041 provided on the inner wall surface of the limiting groove 3011, and the third limiting matching portion 304 is a surface on the first limiting protrusion 4011 facing the limiting rib 3041 and abutting against the limiting rib 3041. The third limiting matching portion 304 and the limiting rib 3041 are arranged in sequence along a direction opposite to the second limiting direction to limit the movement of the transmission member relative to the transmission shaft 4 along a direction opposite to the second limiting direction.

[0118] By providing a limiting rib 3041 on the inner wall of the limiting groove 3011, the limiting rib 3041 abuts against the third limiting portion 403 to limit movement of the transmission member relative to the transmission shaft 4 in a direction opposite to the second limiting direction. This structure enhances the functions of the first limiting protrusion 4011 and the limiting groove 3011, simplifying the structure of the transmission member and the transmission shaft 4.

[0119] Alternatively, as Figure 32 As shown, the transmission member is provided with a mounting hole 303, the transmission shaft 4 is provided in the mounting hole 303, the first limiting matching portion 301 is provided on the inner wall surface of the mounting hole 303, and the second limiting direction is the direction in which the transmission shaft 4 is inserted into the mounting hole 303.

[0120] The mounting hole 303 penetrates the transmission member along its thickness direction. The first position-limiting mating portion 301 is provided on the inner wall surface of the mounting hole 303. For example, the first position-limiting mating portion 301 is a position-limiting groove 3011 provided on the inner wall surface of the mounting hole 303. Integrating the first position-limiting mating portion 301 into the mounting hole 303 can improve the compactness of the transmission member structure.

[0121] Alternatively, as Figure 12 、 Figure 21 、 Figure 22As shown, one of the second limiting portion 402 and the second limiting matching portion 302 is a buckle 4021 , and the other is a slot 3021 adapted to the buckle 4021 . The buckle 4021 is inserted into the slot 3021 and is engaged with the slot 3021 .

[0122] The slot 3021 includes a first slot wall 3022, with the buckle 4021 abutting against the first slot wall 3022. When the second limiting portion 402 is the buckle 4021 and the second limiting mating portion 302 is the slot 3021, the first slot wall 3022 and the buckle 4021 are sequentially arranged along the second limiting direction. Alternatively, the second limiting mating portion 302 is the buckle 4021 and the second limiting portion 402 is the slot 3021, with the first slot wall 3022 and the buckle 4021 sequentially arranged along the direction opposite to the second limiting direction. The cooperation between the buckle 4021 and the slot 3021 achieves limiting of the transmission member in the second limiting direction, resulting in a simple structure.

[0123] like Figure 12 As shown, the second position-limiting engagement portion 302 is provided on a surface of the transmission member that is away from the transmission shaft 4 .

[0124] like Figure 22 As shown, the first limiting portion 401 includes a first limiting protrusion 4011, the second limiting portion 402 includes a buckle 4021, and the transmission shaft 4 is further provided with a support protrusion 404. The support protrusion 404 and the second limiting portion 402 are both located on the surface of the transmission shaft 4 facing the transmission member, and the support protrusion 404 is located between the multiple buckles 4021. A gap is provided between the support protrusion 404 and the buckles 4021 to enhance the deformation capability of the buckles 4021. The support protrusion 404 passes through the mounting hole 303 and is adapted to the mounting hole 303. That is, the outer wall surface of the support protrusion 404 abuts the inner wall surface of the mounting hole 303, further enhancing the limiting effect of the transmission member and the transmission shaft 4 along the first limiting direction. The provision of the support protrusion 404 can also enhance the strength of the transmission shaft 4.

[0125] Alternatively, as Figure 4 and Figure 27 As shown, the driving device also includes a box cover 51, which is arranged between the driving member 7 and the transmission member and abuts against the transmission member to limit the movement of the transmission member in the direction close to the driving member 7, that is, to limit the movement of the transmission member relative to the transmission shaft 4 along the second limiting direction, thereby enhancing the limiting effect of the transmission member moving along the second limiting direction.

[0126] Optionally, a second limiting protrusion 511 is provided on the surface of the box cover 51 facing the transmission member, and the second limiting protrusion 511 abuts against the transmission member to limit the movement of the transmission member in the direction approaching the driving member 7; and / or a third limiting protrusion 305 is provided on the surface of the transmission member facing the box cover 51, and the third limiting protrusion 305 abuts against the box cover 51 to limit the movement of the transmission member in the direction approaching the driving member 7.

[0127] The cover 51 is provided with a connection hole, through which the transmission shaft 4 passes, and is inserted into the mounting hole 303. The second limiting protrusion 511 abuts against the third limiting protrusion 305. The second limiting protrusion 511 is arranged around the circumference of the connection hole, while the third limiting protrusion 305 is arranged around the circumference of the mounting hole 303. The first limiting portion 401 is a first limiting protrusion 4011. The inner wall of the connection hole is provided with a relief groove. The number of relief grooves is equal to the number of first limiting protrusions 4011 and corresponds one-to-one, so that the first limiting protrusion 4011 passes through the relief groove.

[0128] like Figure 10 As shown, the driving device includes a limit member 6, which is arranged between the first link 1 and the second link 2, and is used to limit the movement of the first link 1 toward the second link 2 and / or to limit the movement of the second link 2 toward the first link 1, so as to avoid collision between the first link 1 and the second link 2 during movement.

[0129] Optionally, the limiting member 6 abuts against the first connecting rod 1 to limit the movement of the first connecting rod 1 toward the second connecting rod 2; and / or, the limiting member 6 abuts against the second connecting rod 2 to limit the movement of the second connecting rod 2 toward the first connecting rod 1.

[0130] Optionally, a first abutment rib 63 is provided on the surface of the stopper 6 facing the first connecting rod 1. The first abutment rib 63 abuts the first connecting rod 1. The first abutment rib 63 abuts the first connecting rod 1 to reduce the contact area between the stopper 6 and the first connecting rod 1, thereby reducing the friction between the stopper 6 and the first connecting rod 1. The first abutment rib 63 extends along the length of the stopper 6. There are multiple first abutment ribs 63, and the multiple first abutment ribs 63 are arranged sequentially along the width of the stopper 6.

[0131] A second abutment rib is provided on the surface of the stopper 6 facing the second connecting rod 2. The second abutment rib abuts the second connecting rod 2. This abutment reduces the contact area between the stopper 6 and the second connecting rod 2, thereby reducing friction between the two. The second abutment rib extends along the length of the stopper 6. There are multiple second abutment ribs, each of which is arranged sequentially along the width of the stopper 6.

[0132] like Figure 30 As shown, the surface of the first connecting rod 1 facing the stopper 6 is provided with a third abutting rib 15, which abuts the stopper 6. The third abutting rib 15 abuts the stopper 6 to reduce the contact area between the stopper 6 and the first connecting rod 1, thereby reducing the friction between the stopper 6 and the first connecting rod 1. The third abutting rib 15 extends along the length of the first connecting rod 1. There are multiple first abutting ribs 63, and the multiple third abutting ribs 15 are arranged sequentially along the width of the first connecting rod 1.

[0133] like Figure 29 As shown, the surface of the second connecting rod 2 facing the limiter 6 is provided with a fourth abutting rib 27, which abuts against the limiter 6. The fourth abutting rib 27 abuts against the limiter 6 to reduce the contact area between the limiter 6 and the second connecting rod 2 and reduce the friction between the limiter 6 and the second connecting rod 2. The fourth abutting rib 27 is arranged along the length direction of the second connecting rod 2 ( Figure 9 The number of the fourth abutting ribs 27 is multiple, and the multiple fourth abutting ribs 27 extend along the width direction of the second connecting rod 2 ( Figure 9 f) are set in sequence.

[0134] Alternatively, as Figure 23 As shown, the driving device also includes a mechanism box 5, the first connecting rod 1 and the second connecting rod 2 are at least partially arranged in the mechanism box 5, and move between a position extending out of the mechanism box 5 and a position retracting into the mechanism box 5, and the limit member 6 is installed on the mechanism box 5, so that the limit member 6 is fixed by the mechanism box 5.

[0135] Alternatively, as Figure 23 As shown, the mechanism box 5 is provided with a mounting notch, and the position-limiting member 6 includes a position-limiting body 61 and a stop rib 62. The position-limiting body 61 is provided in the mechanism box 5; the stop rib 62 is provided at the end of the position-limiting body 61 and extends out of the mounting notch. There are multiple stop ribs 62, one at each of the two opposite ends of the position-limiting body 61; the size of the stop rib 62 is larger than the size of the mounting notch to prevent the stop rib 62 from entering the mechanism box 5. The mounting notch is adapted to the position-limiting body 61 and cooperates with the stop rib 62 to achieve positioning of the position-limiting member 6.

[0136] Optionally, the mechanism box 5 includes a box body 52 and a box cover 51 , and the box cover 51 is disposed on the box body 52 ; wherein the limiting member 6 is clamped between the box body 52 and the box cover 51 .

[0137] The box body 52 and the box cover 51 are detachably connected. The position limiting member 6 is clamped between the box body 52 and the box cover 51. When the box cover 51 is covered on the box body 52, the position limiting member 6 can also be positioned.

[0138] Optionally, the first connecting rod 1 is arranged between the limit member 6 and the mechanism box 5, and the surface of the first connecting rod 1 facing the mechanism box 5 abuts against the mechanism box 5 to limit the movement of the first connecting rod 1 toward the mechanism box 5, that is, it moves in the direction away from the limit member 6, further realizing the limitation of the first connecting rod 1 in the direction of the line connecting the limit member 6 and the mechanism box 5; and / or, the second connecting rod 2 is arranged between the limit member 6 and the mechanism box 5, and the surface of the second connecting rod 2 facing the mechanism box 5 abuts against the mechanism box 5 to limit the movement of the second connecting rod 2 toward the mechanism box 5, that is, it moves in the direction away from the limit member 6, further realizing the limitation of the second connecting rod 2 in the direction of the line connecting the limit member 6 and the mechanism box 5.

[0139] Optionally, the power source includes a transmission member, which is drivingly connected to the first connecting rod 1 and the second connecting rod 2. The transmission member is arranged between the first connecting rod 1 and the second connecting rod 2 and abuts against the first connecting rod 1 and / or the second connecting rod 2.

[0140] The transmission member utilizes the cooperation of the first driving part and the first driving structure to achieve abutment with the first connecting rod 1, and the transmission member utilizes the cooperation of the second driving part and the second driving structure to achieve abutment with the second connecting rod 2, thereby preventing the first connecting rod 1 from moving toward the second connecting rod 2 and the second connecting rod 2 from moving toward the first connecting rod 1.

[0141] Alternatively, as Figure 10 As shown, the transmission member and the limiting member 6 are arranged in sequence along the length direction of the first connecting rod 1 or the second connecting rod 2, so that different positions of the length direction of the first connecting rod 1 or the second connecting rod 2 are limited by the transmission member and the limiting member 6 respectively to avoid collision at different positions of the length direction of the first connecting rod 1 and the second connecting rod 2.

[0142] Example 1:

[0143] like Figure 1-22 As shown, the first driving groove 11 is a curved groove, and the second driving groove 12 is a curved groove.

[0144] The first boss 31 is sized to match the first drive slot 11. That is, when the first boss 31 is located in the first drive slot 11 and slides relative to the first drive slot 11, it can drive the first connecting rod 1 to move relative to the rotating member 3. In other words, the cooperation between the first boss 31 and the first drive slot 11 can provide a driving force for the movement of the first connecting rod 1. The second boss 32 is sized to match the second drive slot 12.

[0145] The first boss 31 cooperates with the first drive slot 11, and the second boss 32 cooperates with the second drive slot 12, thereby jointly realizing the movement of the first connecting rod 1. Compared to the situation where only one boss and one drive slot cooperate between the first connecting rod 1 and the rotating member 3, the present application provides the arrangement where the first boss 31 cooperates with the first drive slot 11, and the second boss 32 cooperates with the second drive slot 12, thereby realizing stable movement of the first connecting rod 1. Furthermore, while the structures of the first drive slot 11 and the second drive slot 12 are relatively simple, the superposition of the movement of the first connecting rod 1 in the first extending direction and the movement in the first deviating direction can be realized.

[0146] like Figure 7 As shown, at least one of the first driving groove 11 and the second driving groove 12 needs to be a curved groove to meet the requirements of the motion trajectory of the first connecting rod 1.

[0147] Optionally, when both the first driving groove 11 and the second driving groove 12 are curved grooves, the first driving groove 11 and the second driving groove 12 are arranged opposite to each other.

[0148] When the first connecting rod 1 moves a preset displacement, the sliding amount of the first boss 31 in the first driving groove 11 relative to the first driving groove 11 and the sliding amount of the second boss 32 in the second driving groove 12 relative to the second driving groove 12 are different. The first driving groove 11 and the second driving groove 12 are arranged relative to each other, so that the one with a larger sliding amount plays a major role in driving the movement of the first connecting rod 1, and the one with a smaller sliding amount plays a role similar to a fulcrum or a rotation point.

[0149] like Figure 7 As shown, the first driving groove 11 and the second driving groove 12 are both provided on the first connecting rod 1, and the first driving groove 11 and the second driving groove 12 are arranged opposite to each other. The first driving groove 11 and the second driving groove 12 are both along the width direction of the first connecting rod 1 ( Figure 7 b) extends along the length direction of the first connecting rod 1 ( Figure 7 Set in sequence. Figure 11 As shown, the first protrusion 31 and the second protrusion 32 are sequentially arranged along the circumference of the rotating member 3 .

[0150] In this way, the cooperation between the first boss 31 and the first drive groove 11, and the cooperation between the second boss 32 and the second drive groove 12 can meet the requirements for the motion trajectory of the first connecting rod 1, and make the first drive groove 11 and the second drive groove 12 occupy a small volume on the first connecting rod 1, thereby reducing the size of the first connecting rod 1.

[0151] The extension directions of the first driving groove 11 and the second driving groove 12 are not parallel to the length direction of the first connecting rod 1. The first boss 31 slides relative to the first driving groove 11 along the extension direction of the first driving groove 11, and the second boss 32 slides relative to the second driving groove 12 along the extension direction of the second driving groove 12. In this way, the cooperation between the first boss 31 and the first driving groove 11 can drive the first connecting rod 1 to move; the cooperation between the second boss 32 and the second driving groove 12 can drive the first connecting rod 1 to move.

[0152] Alternatively, as Figure 7 As shown, when both the first drive groove 11 and the second drive groove 12 are curved grooves, the first drive groove 11 includes a first sub-drive groove 111 and a second sub-drive groove 112, and the second sub-drive groove 112 is connected to the first sub-drive groove 111, and when the air guide plate 1002 moves from the first position to the second position, the first protrusion 31 slides through the first sub-drive groove 111 and the second sub-drive groove 112 in sequence; the length of the first sub-drive groove 111 is smaller than the length of the second sub-drive groove 112, and the curvature of the first sub-drive groove 111 is greater than the curvature of the second sub-drive groove 112.

[0153] Both the first sub-drive slot 111 and the second sub-drive slot 112 are curved slots, and the curvature of the first sub-drive slot 111 is greater than that of the second sub-drive slot 112. This results in a greater force acting on the first sub-drive slot 111 when the first protrusion 31 is located within the first sub-drive slot 111, which is greater than the force acting on the second sub-drive slot 112 when the first protrusion 31 is located within the second sub-drive slot 112. This allows the air deflector 1002 to open, changing its speed from zero to greater than zero. Because the air deflector 1002 takes a relatively short time to open, the length of the first sub-drive slot 111 is shorter than that of the second sub-drive slot 112.

[0154] A smooth transition is adopted at the connection point between the first sub-driving groove 111 and the second sub-driving groove 112 .

[0155] Optionally, when both the first drive groove 11 and the second drive groove 12 are curved grooves, the second drive groove 12 includes a third sub-drive groove 121 and a fourth sub-drive groove 122. The fourth sub-drive groove 122 is connected to the third sub-drive groove 121, and when the air deflector 1002 moves from the first position to the second position, the second protrusion 32 slides through the third sub-drive groove 121 and the fourth sub-drive groove 122 in sequence. The length of the third sub-drive groove 121 is shorter than that of the fourth sub-drive groove 122, and the curvature of the third sub-drive groove 121 is greater than that of the fourth sub-drive groove 122.

[0156] Both the third sub-drive slot 121 and the fourth sub-drive slot 122 are curved slots, and the curvature of the third sub-drive slot 121 is greater than that of the fourth sub-drive slot 122. This results in a greater force acting on the third sub-drive slot 121 when the second protrusion 32 is located within the third sub-drive slot 121, which is greater than the force acting on the fourth sub-drive slot 122 when the second protrusion 32 is located within the fourth sub-drive slot 122. This activates the opening process of the air deflector 1002, thereby changing the speed of the air deflector 1002 from zero to greater than zero. Because the opening process of the air deflector 1002 is relatively short, the length of the third sub-drive slot 121 is shorter than that of the fourth sub-drive slot 122.

[0157] Optionally, the plurality of first active parts include a fourth sub-active part; one of the fourth sub-active part and the first driven part includes a fourth protrusion 34 , and the other includes a fourth driving slot 13 .

[0158] The first groove structure also includes a fourth drive groove 13; the first protrusion structure also includes a fourth protrusion 34. When the air guide plate 1002 opens from the first position to the second position, the fourth protrusion 34 is arranged in the fourth drive groove 13 and can slide relative to the fourth drive groove 13; wherein, the fourth drive groove 13 is a curved groove.

[0159] The fourth protrusion 34 matches the size of the fourth driving slot 13 .

[0160] During the movement of the air guide plate 1002 from the first position to the second position, the first boss 31 is located in the first drive groove 11 for at least part of its stroke, the second boss 32 is always located in the second drive groove 12, and the fourth boss 34 is always located in the fourth drive groove 13. In this way, there are always at least two bosses cooperating with at least two drive grooves at the same time, and the fourth drive groove 13 is a curved groove, so that the first connecting rod 1 has both a sub-movement that deviates from the first direction of movement and a sub-movement that extends in the first direction of movement.

[0161] When the fourth driving groove 13 and the first driving groove 11 and the second driving groove 12 are all located in the first connecting rod 1 or the rotating member 3 , the fourth driving groove 13 intersects with the extension line of the first driving groove 11 and / or intersects with the extension line of the second driving groove 12 .

[0162] Taking the first groove structure provided on the first connecting rod 1 as an example, the extension line of the first driving groove 11 and / or the second driving groove 12 intersects with the fourth driving groove 13, which can fully utilize the space of the first connecting rod 1 and avoid the first connecting rod 1 being too large, thereby reducing the size of the driving device.

[0163] During the opening process of the air guide plate 1002, the air guide plate 1002 passes through the first position, the third position and the second position in sequence. Figure 2 As shown, the first boss 31 is located in the first driving groove 11 for at least part of its stroke and can slide relative to the first driving groove 11, the second boss 32 is located in the second driving groove 12 and can slide relative to the second driving groove 12, and the fourth boss 34 is located in the fourth driving groove 13 and can move relative to the fourth driving groove 13. From the third position to the second position, as shown Figure 13 As shown, the first boss 31 is disengaged from the first driving groove 11 , the second boss 32 is located in the second driving groove 12 and can slide relative to the second driving groove 12 , and the fourth boss 34 is located in the fourth driving groove 13 and can slide relative to the fourth driving groove 13 .

[0164] In other words, from the first position to the second position, the second boss 32 always cooperates with the second drive groove 12, the fourth boss 34 always cooperates with the fourth drive groove 13, and the first boss 31 first cooperates with the first drive groove 11, and then separates from the first drive groove 11, that is, no longer cooperates, to ensure that in the process of the air guide plate 1002 moving from the first position to the second position, there are always at least two bosses respectively cooperating with the two drive grooves, and the first boss 31 first cooperates with the first drive groove 11 and then no longer cooperates, that is, intermittent cooperation, which can avoid the size of the first drive groove 11 being too large.

[0165] Optionally, when the fourth driving groove 13 and the first driving groove 11 and the second driving groove 12 are all located in the first connecting rod 1 , the first connecting rod 1 is provided with an avoidance gap 191 , and the rotation axis of the rotating member 3 is provided in the avoidance gap 191 .

[0166] When the rotating member 3 rotates around its own rotation axis, it drives the first connecting rod 1 to move, and the avoidance gap 191 moves with the first connecting rod 1, that is, the avoidance gap 191 moves relative to the rotation axis of the rotating member 3, so that the first protrusion structure on the rotating member 3 cooperates with different positions of the first groove structure.

[0167] like Figure 6 and Figure 7 As shown, the first drive groove 11 and the second drive groove 12 are located on one side of the avoidance gap 191, and the fourth drive groove 13 is arranged on the other side of the avoidance gap 191, so that when the rotating member 3 rotates, the intermittent cooperation between the first boss 31 and the first drive groove 11 can be satisfied, and there are at least two bosses on the rotating member 3 that can cooperate with the two drive grooves respectively.

[0168] Optionally, the first slot structure further includes a ninth driving slot 14, and the ninth driving slot 14 is connected to the fourth driving slot 13, such as Figure 15 、 Figure 17 and Figure 19 As shown, during the process of the air guide plate 1002 opening from the second position to the fourth position, the fourth boss 34 is located in the ninth drive groove 14 and can slide relative to the ninth drive groove 14; wherein, during the process of the air guide plate 1002 moving from the second position to the fourth position, the ninth drive groove 14 is an arc-shaped groove whose center is the rotation center of the rotating part 3.

[0169] The fourth protrusion 34 matches the size of the ninth driving slot 14 .

[0170] When the air guide plate 1002 continues to open from the second position, the fourth boss 34 slides from the fourth drive groove 13 into the ninth drive groove 14 and slides relative to the ninth drive groove 14, and the first boss 31 disengages from the first drive groove 11. In the initial stage of continued opening, the second boss 32 is still located in the second drive groove 12. After the initial stage, the second boss 32 also disengages from the second drive groove 12. The ninth drive groove 14 is an arc-shaped groove, and the center of the ninth drive groove 14 is the rotation center of the rotating member 3. Therefore, when the air guide plate 1002 continues to open from the second position, the rotating member 3 rotates, and the fourth boss 34 rotates around the rotation center of the rotating member 3 relative to the ninth drive groove 14, and the first connecting rod 1 is stationary.

[0171] The curvature of the ninth driving groove 14 is greater than the curvature of the fourth driving groove 13 .

[0172] The fourth drive groove 13 extends along the length direction of the first connecting rod 1. The first drive groove 11 and the fourth drive groove 13 are sequentially arranged along the width direction of the first connecting rod 1 and / or the second drive groove 12 and the fourth drive groove 13 are sequentially arranged along the width direction of the first connecting rod 1 to reduce the length dimension of the first connecting rod 1.

[0173] like Figure 15 As shown, the drive device further includes an eleventh drive slot 16, which is disposed in the first connecting rod 1 or the rotating member 3 where the second drive slot 12 is located. The eleventh drive slot 16 is connected to the second drive slot 12 and is adapted to fit with the second protrusion 32. As the air deflector 1002 continues to open from the second position, the second protrusion 32 slides from the second drive slot 12 into the eleventh drive slot 16 and is able to slide relative to the eleventh drive slot 16 until the air deflector 1002 moves to the seventh position.

[0174] The eleventh driving groove 16 is an arc-shaped groove, and the center of the circle where the eleventh driving groove 16 is located is the rotation center of the rotating part 3 when the air guide plate 1002 moves from the second position to the fourth position. In this way, when the air guide plate 1002 moves from the second position to the seventh position, the sliding of the second boss 32 relative to the eleventh rotating groove will not drive the first connecting rod 1 to move, but will also make the position of the first connecting rod 1 more stable, and will not hinder the rotation of the rotating part 3, that is, it will not affect the rotating part 3 to continue to drive the second connecting rod 2 to move.

[0175] When the air deflector 1002 continues to move from the seventh position to the fourth position, the second protrusion 32 disengages from the eleventh drive slot 16, preventing the second protrusion 32 from always engaging with the eleventh drive slot 16, which would otherwise cause the eleventh drive slot 16 to be oversized. The air deflector 1002 passes through the second position, the seventh position, and the fourth position in sequence during its opening process.

[0176] When both the eleventh drive slot 16 and the fourth drive slot 13 are provided in the first connecting rod 1 or the rotating member 3, the fourth drive slot 13 is provided with an exit notch 131 for the second boss 32 to pass through. After the second boss 32 slides out of the eleventh drive slot 16, as the rotating member 3 continues to rotate, the second boss 32 passes out of the exit notch 131. After the first boss 31 slides out of the first drive slot 11, as the rotating member 3 continues to rotate, the first boss 31 passes out of the exit notch 131.

[0177] When the eleventh drive groove 16 and the ninth drive groove 14 are both arranged on the first connecting rod 1 or the rotating part 3, during the movement of the air guide plate 1002 from the second position to the fourth position, the circles where the eleventh drive groove 16 and the ninth drive groove 14 are located are concentric circles, and the centers of the concentric circles are both the rotation centers of the rotating part 3.

[0178] When the eleventh driving groove 16 and the fourth driving groove 13 are both arranged in the first connecting rod 1 or the rotating member 3, the extension line of the eleventh driving groove 16 intersects with the fourth driving groove 13 to reduce the size of the first connecting rod 1 or the rotating member 3 where the eleventh driving groove 16 and the fourth driving groove 13 are located.

[0179] During the movement of the air guide plate 1002 from the second position to the fourth position, the ninth drive groove 14 and the eleventh drive groove 16 are arranged on two opposite sides of the rotation center of the rotating member 3. On the one hand, compared with being arranged on the same side of the rotation center, being arranged on opposite sides can make the first connecting rod 1 or the rotating member 3 provided with the ninth drive groove 14 and the eleventh drive groove 16 more compact, and the ninth drive groove 14 and the eleventh drive groove 16 are arranged in sequence along the length direction of the first connecting rod 1.

[0180] The seventh position is located between the second position and the surround air supply position.

[0181] like Figure 17 As shown, the driving device also includes a tenth boss 36, which is arranged on the first connecting rod 1 or the rotating part 3 where the fourth boss 34 is located; when the air guide plate 1002 moves from the first position to the second position, the tenth boss 36 is arranged outside the ninth driving groove 14, and when the air guide plate 1002 moves from the second position to the fourth position, the tenth boss 36 is arranged in the ninth driving groove 14 and can slide relative to the ninth driving groove 14.

[0182] The tenth boss 36 is adapted to fit within the ninth drive slot 14. The distance between the tenth boss 36 and the rotational center of the rotating member 3 is equal to the distance between the fourth boss 34 and the rotational center of the rotating member 3. For example, if both the tenth boss 36 and the fourth boss 34 are provided on the rotating member 3, the tenth boss 36 and the fourth boss 34 are sequentially arranged along the circumference of the rotating member 3.

[0183] When the air guide plate 1002 is not opened to the second position, the tenth boss 36 is located in the avoidance gap 191, and the fourth driving groove 13 is provided with a through-port 132. When the air guide plate 1002 is opened to the second position, the tenth boss 36 enters the ninth driving groove 14 through the through-port 132.

[0184] like Figure 13 As shown, when the air guide plate 1002 moves from the second position to the fourth position, the fourth boss 34 and the tenth boss 36 are both located in the ninth driving groove 14 and can slide relative to the ninth driving groove 14, thereby improving the position stability of the first connecting rod 1.

[0185] Alternatively, as Figure 9 and Figure 12As shown, one of the third sub-active portion and the second driven portion includes a third boss 33, and the other includes a third drive slot 21. The first boss 31 is disposed in the first drive slot 11 and is capable of sliding relative to the first drive slot 11, the second boss 32 is disposed in the second drive slot 12 and is capable of sliding relative to the second drive slot 12, and the third boss 33 is disposed in the third drive slot 21 and is capable of sliding relative to the third drive slot 21, so that the first connecting rod 1 and the second connecting rod 2 jointly drive the air deflector 1002 from the first position to the second position.

[0186] Optionally, the plurality of second active parts include a fifth sub-active part; one of the fifth sub-active part and the second driven part includes a fifth protrusion 35 , and the other includes a fifth driving slot 23 .

[0187] When the first drive groove 11 and the second drive groove 12 are both curved grooves, the second groove structure includes the third drive groove 21 and the fifth drive groove 23; the second protrusion structure includes the third boss 33 and the fifth boss 35; in the process of the air guide plate 1002 opening from the first position to the second position, the third boss 33 is arranged in the third drive groove 21 and can slide relative to the third drive groove 21, and the fifth boss 35 is arranged in the fifth drive groove 23 and can slide relative to the fifth drive groove 23; wherein, the third drive groove 21 is a straight groove, and the fifth drive groove 23 is a curved groove.

[0188] The third protrusion 33 is adapted to the size of the third driving slot 21 . The fifth protrusion 35 is adapted to the size of the fifth driving slot 23 .

[0189] The cooperation between the third boss 33 and the third drive slot 21, and the cooperation between the fifth boss 35 and the fifth drive slot 23, jointly drive the movement of the second connecting rod 2. Furthermore, the third drive slot 21 is a straight slot, and the fifth drive slot 23 is a curved slot, so that the second connecting rod 2 moves along a straight trajectory when the air deflector 1002 opens from the first position to the second position.

[0190] Optionally, when the third drive groove 21 and the fifth drive groove 23 are both provided in the second connecting rod 2, the third drive groove 21 and the fifth drive groove 23 are not parallel to the length direction of the second connecting rod 2, so that when the third boss 33 cooperates with the third drive groove 21, a force can be applied to the third drive groove 21 to drive the second connecting rod 2 to move, and when the fifth boss 35 cooperates with the fifth drive groove 23, a force can be applied to the fifth drive groove 23 to drive the second connecting rod 2 to move.

[0191] The extension line of the third driving groove 21 intersects with the fifth driving groove 23 , which on the one hand satisfies the requirements for the motion trajectory of the second connecting rod 2 , and on the other hand reduces the volume occupied by the third driving groove 21 and the fifth driving groove 23 .

[0192] Alternatively, as Figure 9As shown, the second slot structure also includes a tenth drive slot 22, which is connected to the third drive slot 21. When the air guide plate 1002 is opened from the second position to the fourth position, the third boss 33 is located in the tenth drive slot 22 and can slide relative to the tenth drive slot 22; wherein, the tenth drive slot 22 is connected to the side of the third drive slot 21 away from the air outlet, and forms an angle with the connection point of the third drive slot 21, and the tenth drive slot 22 is an arc-shaped slot.

[0193] The third protrusion 33 matches the size of the tenth driving slot 22 .

[0194] like Figure 16 As shown, when the air deflector 1002 continues to open from the second position, the third protrusion 33 slides into the tenth driving groove 22 and can slide relative to the tenth driving groove 22 to drive the second connecting rod 2 to move. The tenth driving groove 22 is an arc-shaped groove, so as to drive the movement trajectory of the second connecting rod 2 to be an arc.

[0195] Since the second connecting rod 2 is always moving during the rotation of the rotating member 3 , the center of the arc where the tenth driving groove 22 is located deviates from the rotation center of the rotating member 3 when the air guide plate 1002 moves from the second position to the fourth position.

[0196] Alternatively, as Figure 16 As shown, the second slot structure also includes a thirteenth drive slot 24, which is connected to the fifth drive slot 23. When the air guide plate 1002 is opened from the second position to the fourth position, the fifth boss 35 is located in the thirteenth drive slot 24 and can slide relative to the thirteenth drive slot 24; wherein, the thirteenth drive slot 24 is connected to the side of the fifth drive slot 23 away from the air outlet, and forms an angle with the connection point of the fifth drive slot 23. The thirteenth drive slot 24 is an arc-shaped slot, and the circle where the thirteenth drive slot 24 is located is concentric with the circle where the tenth drive slot 22 is located.

[0197] The size of the fifth protrusion 35 matches the size of the thirteenth driving groove 24 .

[0198] As the air deflector 1002 continues to open from the second position, the fifth boss 35 slides into the thirteenth drive slot 24 and is able to slide relative to the thirteenth drive slot 24, cooperating with the third boss 33 and the tenth drive slot 22 to jointly drive the movement of the second connecting rod 2. The thirteenth drive slot 24 and the tenth drive slot 22 are both arc-shaped slots, and the circles within which the two arc-shaped slots lie are concentric circles. During the movement of the air deflector 1002 from the second position to the fourth position, the center of the concentric circles does not coincide with the rotation center of the rotating member 3, thereby driving the movement trajectory of the second connecting rod 2 to be arc-shaped.

[0199] The driving device includes a connecting rod and a power source. The connecting rod is movably connected to the air deflector 1002 and is provided with a driving structure. The power source includes a driving part, which cooperates with the driving structure to drive the connecting rod to move, thereby driving the air deflector 1002 to open and close.

[0200] Among them, the driving structure includes a first sub-driving structure, and the driving part includes a first sub-driving part. During the movement of the air guide plate 1002, the first sub-driving structure moves relative to the first sub-driving part between a mating position where the two are mated and a disengaged position where the mating is released.

[0201] The connecting rod includes a first connecting rod 1 and / or a second connecting rod 2. When the connecting rod includes the first connecting rod 1 but does not include the second connecting rod 2, the driving structure includes a first driving structure, the first driving structure includes a first sub-driving structure, the driving portion includes a first driving portion, and the first driving portion includes a first sub-driving portion. When the connecting rod includes the second connecting rod 2 but does not include the first connecting rod 1, the driving structure includes a second driving structure, the second driving structure includes a first sub-driving structure, the driving portion includes a second driving portion, and the second driving portion includes a first sub-driving portion. When the connecting rod includes the first connecting rod 1 and the second connecting rod 2, the driving structure includes a first driving structure and a second driving structure, the first driving structure and / or the second driving structure include a first sub-driving structure, the driving portion includes a first driving portion and a second driving portion, and the first driving portion and / or the second driving portion include a first sub-driving portion.

[0202] The power source includes a rotating member 3, and the rotating member 3 includes a driving part; or the power source can also be in other forms, for example, the driving part includes a gear, the driving structure includes a rack, and the engagement of the gear and the rack drives the connecting rod to move.

[0203] In the disengaged position, the first sub-driving portion is disengaged from the first sub-driving structure, and the first sub-driving portion no longer drives the first sub-driving structure.

[0204] As the connecting rod moves, the first sub-drive structure moves accordingly. If the first sub-drive structure and the first sub-drive unit are always in a mating state (at this time, in the mating position), the size of the first sub-drive structure or the first sub-drive unit needs to be sufficiently large. Therefore, in this application, the first sub-drive structure and the first sub-drive unit have a disengagement position, thereby reducing the size of the first sub-drive structure or the first sub-drive unit and avoiding excessive size of the connecting rod or the power source.

[0205] Optionally, one of the first sub-drive structure and the first sub-drive portion is a first protrusion, and the other is a first slot adapted to the first protrusion; in the mating position, the first protrusion is located in the first slot and can slide relative to the first slot to drive the connecting rod to move; in the disengaged position, the first protrusion disengages from the first slot.

[0206] The first protrusion can be the first boss 31, and the first slot is the first drive slot 11. During the movement of the air guide plate 1002 from the first position to the second position, the first drive slot 11 is first engaged with the first boss 31. At this time, the first boss 31 is located in the first drive slot 11 and can slide relative to the first drive slot 11, which is the engaged position, and then separated from the first boss 31, which is the disengaged position.

[0207] The first protrusion may also be a fifth protrusion 35, and the first slot may be the fifth drive slot 23. In the initial stage of the air deflector 1002 starting to move from the first position, the fifth protrusion 35 is separated from the fifth drive slot 23. As the air deflector 1002 continues to open, before the air deflector 1002 reaches the third position, the fifth protrusion 35 enters the fifth drive slot 23 and is able to slide relative to the fifth drive slot 23, reaching a mating position.

[0208] Optionally, the driving structure also includes a second sub-driving structure, and the driving part also includes a second sub-driving part. During the movement of the air guide plate 1002, the second sub-driving structure has a mating position that cooperates with the second sub-driving part; wherein, when the first sub-driving structure is in the disengaged position, the second sub-driving structure is in the mating position.

[0209] When the first sub-driving structure is in the disengaged position, the second sub-driving structure cooperates with the second sub-driving portion, so that the connecting rod can continue to move under the cooperation of the second sub-driving structure and the second sub-driving portion.

[0210] When the connecting rod includes the first connecting rod 1 but does not include the second connecting rod 2, the first driving structure also includes a second sub-driving structure, and the first driving unit also includes the second sub-driving unit. When the connecting rod includes the second connecting rod 2 but does not include the first connecting rod 1, the second driving structure includes the second sub-driving structure, and the second driving unit includes the second sub-driving unit. When the connecting rod includes the first connecting rod 1 and the second connecting rod 2, the first driving structure and / or the second driving structure including the first sub-driving structure also include the second sub-driving structure, and the first driving unit and / or the second driving unit including the first sub-driving unit also include the first sub-driving unit.

[0211] Optionally, the second sub-driving structure moves relative to the second sub-driving portion between an engaged position and a disengaged position for disengagement.

[0212] The second sub-driving structure and the second sub-driving part have a disengagement position, so that the size of the second sub-driving structure or the second sub-driving part can be reduced, and the connecting rod or the power source can be prevented from being too large in size.

[0213] Optionally, one of the second sub-drive structure and the second sub-drive portion is a second protrusion, and the other is a second slot adapted to the second protrusion; in the mating position, the second protrusion is located in the second slot and can slide relative to the second slot to drive the connecting rod to move; in the disengaged position, the second protrusion disengages from the second slot.

[0214] When the first protrusion is the first protrusion 31 and the first slot is the first driving slot 11, the second protrusion is the second protrusion 32 and the second slot is the second driving slot 12. When the first protrusion is the fifth protrusion 35 and the first slot is the fifth driving slot 23, the second protrusion is the third protrusion 33 and the second slot is the third driving slot 21.

[0215] Optionally, the driving structure further includes a third sub-driving structure, and the driving unit further includes a third sub-driving unit. During the movement of the air guide plate 1002, the third sub-driving structure always cooperates with the third sub-driving unit.

[0216] When the connecting rod includes the first connecting rod 1 but not the second connecting rod 2, the first driving structure also includes a third sub-driving structure, and the first driving unit also includes the third sub-driving unit. When the connecting rod includes the second connecting rod 2 but not the first connecting rod 1, the second driving structure includes the third sub-driving structure, and the second driving unit includes the third sub-driving unit. When the connecting rod includes the first connecting rod 1 and the second connecting rod 2, the first driving structure and / or the second driving structure including the first sub-driving structure also include the third sub-driving structure, and the first driving unit and / or the second driving unit including the first sub-driving unit also include the third sub-driving unit.

[0217] The third sub-drive structure always cooperates with the third sub-drive unit, ensuring that the third sub-drive unit always provides driving force to the third sub-drive structure, ensuring smooth movement of the connecting rod. Furthermore, when the second sub-drive structure and the second sub-drive unit are in the disengaged position, the third sub-drive structure always cooperates with the third sub-drive unit, ensuring that the movement trajectory of the connecting rod meets the requirements.

[0218] Optionally, one of the third sub-drive structure and the third sub-drive portion is a third protrusion, and the other is a third slot adapted to the third protrusion; in the mating position, the third protrusion is located in the third slot and can slide relative to the third slot to drive the connecting rod to move; in the disengaged position, the third protrusion disengages from the third slot.

[0219] When the first protrusion is the first protrusion 31 and the first slot is the first driving slot 11 , the third protrusion is the fourth protrusion 34 , and the third slot includes the fourth driving slot 13 and the ninth driving slot 14 .

[0220] Optionally, the third sub-driving structure is provided with an avoidance groove, and when the first sub-driving structure is in the escape position, the first sub-driving part passes through the avoidance groove.

[0221] The fourth driving groove 13 is provided with a notch 131, which is an avoidance groove. After the first boss 31 is disengaged from the first driving groove 11 and the second boss 32 is disengaged from the second driving groove 12, the first boss 31 and the second boss 32 are successively disengaged from the avoidance groove as the rotating part 3 moves.

[0222] The drive mechanism includes a connecting rod, a rotating member 3, a power trough structure, and a drive column structure. One of the power trough structure and the drive column structure is located on the connecting rod, and the other of the power trough structure and the drive column structure is located on the rotating member 3. The connecting rod is movably connected to the air deflector 1002 and includes the aforementioned first connecting rod 1 and / or second connecting rod 2.

[0223] The power slot structure includes a first slot structure, and the drive column structure includes a first protrusion structure. And / or, the power slot structure includes a second slot structure, and the drive column structure includes a second protrusion structure.

[0224] The power slot structure includes a first power slot and a second power slot. The driving column structure cooperates with the first power slot and the second power slot to drive the connecting rod to move, thereby driving the air guide plate 1002 to move.

[0225] The driving column structure includes a first driving column and a second driving column.

[0226] One of the first drive column and the first power slot is provided on the connecting rod, and the other of the first drive column and the first power slot is provided on the rotating member 3; the second drive column is provided on the connecting rod or the rotating member 3 where the first drive column is provided; and the second power slot is provided on the connecting rod or the rotating member 3 where the first power slot is provided. That is, both the first drive column and the second drive column are provided on the first connecting rod 1, and both the first power slot and the second power slot are provided on the rotating member 3, or both the first drive column and the second drive column are provided on the rotating member 3, and both the first power slot and the second power slot are provided on the first connecting rod 1, or both the first drive column and the second drive column are provided on the second connecting rod 2, and both the first power slot and the second power slot are provided on the rotating member 3, or both the first drive column and the second drive column are provided on the rotating member 3, and both the first power slot and the second power slot are provided on the second connecting rod 2.

[0227] When the rotating member 3 rotates, the first driving column cooperates with the first power groove, and the second driving column cooperates with the second power groove to drive the connecting rod to move, thereby driving the air guide plate 1002 to move.

[0228] When the rotating member 3 rotates, the first driving column is located in the first power groove and slides relative to the first power groove, and the second driving column is located in the second power groove and slides relative to the second power groove to drive the connecting rod to move.

[0229] The extension line of the first power trough intersects with the extension line of the second power trough, so that the first power trough and the second power trough are staggered, thereby reducing the space occupied by the first power trough and the second power trough.

[0230] The first power slot and the second power slot may be the first driving slot 11 and the fourth driving slot 13 respectively, the corresponding first driving column is the first protruding column 31 , and the second driving column is the fourth protruding column 34 .

[0231] The drive device also includes a third drive column and a third power trough. The third drive column is located on the first connecting rod 1, second connecting rod 2, or rotating member 3 where the first drive column is located; the third power trough is located on the first connecting rod 1, second connecting rod 2, or rotating member 3 where the first power trough is located. In other words, the third drive column and the first drive column are both located on the first connecting rod 1, second connecting rod 2, or rotating member 3, and the third power trough and the first power trough are both located on the first connecting rod 1, second connecting rod 2, or rotating member 3.

[0232] The third power groove is arranged opposite to the first power groove, and an extension line of the third power groove intersects with an extension line of the second power groove.

[0233] The third power slot may be the second driving slot 12 , and correspondingly, the third driving column may be the third protruding column 33 .

[0234] The first power slot can also be the third drive slot 21, and the first drive column can be the third protrusion 33. In this case, the second power slot can be the fifth drive slot 23, and the second drive column can be the fifth protrusion 35. Alternatively, the first power slot can also be the tenth drive slot 22, and the first drive column can be the third protrusion 33. In this case, the second power slot can be the fifth drive slot 23, and the second drive column can be the fifth protrusion 35.

[0235] The first power groove and the second power groove intersect, and it is not necessary for the extension line of the first power groove and the extension line of the second power groove to intersect. This can further reduce the size of the first connecting rod 1, the second connecting rod 2 or the rotating part 3 where the first power groove and the second power groove are located.

[0236] The drive post structure includes a fifth drive post. During rotation of the rotating member 3, the fifth drive post sequentially engages with the first and second drive slots. The first drive slot is non-arc-shaped, while the second drive slot is arc-shaped. During movement of the air deflector 1002 from the second position to the fourth position, the center of the arc is not the rotation center of the rotating member 3. In this case, the first drive slot can be the third drive slot 21, the fifth drive post can be the third protrusion 33, and the second drive slot can be the tenth drive slot 22. Alternatively, the first drive slot can be the fifth drive slot 23, the fifth drive post can be the fifth protrusion 35, and the second drive slot can be the thirteenth drive slot 24.

[0237] The device for driving the air deflector 1002 includes a first protruding post and a reversing slot. One of the first protruding post and the reversing slot is located on the second connecting rod 2, and the other is located on the rotating member 3. The reversing slot has two ends in the longitudinal direction, namely a first end 211 and a second end 212. During the opening process of the air deflector 1002, the first protruding post is located in the reversing slot and slides relative to the reversing slot first in a first direction and then in a second direction. The first direction is from the first end 211 to the second end 212, and the second direction is from the second end 212 to the first end 211.

[0238] Optionally, the reversing groove is a straight groove, and a non-zero angle exists between the reversing groove and the length direction of the second connecting rod 2. The reversing groove can be the third driving groove 21, and the first protruding column is the third protruding column 33.

[0239] Optionally, the reversing groove further includes an intermediate section 215, which is disposed between the first end 211 and the second end 212. When the air deflector 1002 is in the closed position (i.e., the first position), the first protruding column is located in the intermediate section 215. Thus, as the air deflector 1002 opens, the first protruding column first slides in the first direction relative to the reversing groove, slides to the first end 211, and then slides in the second direction.

[0240] The power source for the air conditioner air deflector 1002 also includes a second protruding post and a first adapter slot, one of which is provided on the second connecting rod 2, and the other on the rotating member 3. During the opening process of the air deflector 1002, when the first protruding post moves a predetermined displacement in the first direction relative to the reversing slot, the second protruding post switches from a non-engaging position outside the first adapter slot to an engaging position in which it slides into the first adapter slot, thereby engaging the first protruding post with the reversing slot and the second protruding post with the first adapter slot, thereby jointly driving the movement of the air deflector 1002.

[0241] The movement of the first protrusion relative to the reversing groove enables the second protrusion to switch between a non-engaging position and an engaging position, thereby flexibly adjusting the position of the second protrusion. In the engaging position, the second protrusion slides into and relative to the first adapter groove. At this time, the first protrusion is located in the reversing groove and moves relative to the reversing groove in the second direction, thereby jointly driving the movement of the second connecting rod 2.

[0242] The first adapter groove may be the fifth driving groove 23 , and in this case, the second protruding column is the fifth protruding column 35 .

[0243] The rotating member 3 is connected to the driven member, and the driven member includes a first driven member, which can be the first connecting rod 1 or the second connecting rod 2. The following description will be made by taking the first driven member as the first connecting rod 1 as an example. Figure 11As shown, the first driven member includes a first driven portion, the surface of the rotating member 3 includes a first surface 306, and multiple first active portions are provided on the first surface 306. The multiple first active portions are configured to cooperate with the first driven portion to drive the first driven member to move. At least two of the multiple first active portions are arranged sequentially along the circumference of the rotating member 3, thereby making the layout of the multiple first active portions more reasonable and reducing the size of the rotating member 3. For example, the multiple first active portions include a first boss 31 and a second boss 32, and the first boss 31 and the second boss 32 are arranged sequentially along the circumference of the rotating member 3.

[0244] Optionally, at least two of the plurality of first active portions are located at unequal distances from the rotation center of the rotating member 3, thereby making the layout of the plurality of first active portions more rational and reducing the size of the rotating member 3. For example, the plurality of first active portions include a fourth protrusion 34 and a first protrusion 31, and the distance between the fourth protrusion 34 and the rotation center of the rotating member 3 is smaller than the distance between the first protrusion 31 and the rotation center of the rotating member 3.

[0245] At least two of the multiple first active portions have unequal heights, such that the first active portions are arranged in a staggered manner along the thickness direction of the rotating member 3. One of the first active portion and the first driven portion is a first groove-like structure, and the other is a first columnar structure. The first columnar structure is located within the mating first groove-like structure and is capable of moving relative to the first groove-like structure. When the first active portion is a first columnar structure, i.e., includes at least one of the first protrusion 31, the second protrusion 32, the fourth protrusion 34, and the tenth protrusion 36, the height of the first active portion is the height of the protrusion protruding from the first surface 306. When the first active portion is a first groove-like structure, i.e., includes at least one of the first drive groove 11, the second drive groove 12, the fourth drive groove 13, the ninth drive groove 14, and the eleventh drive groove 16, the height of the first active portion is the depth of the groove depression.

[0246] At least two of the plurality of first columnar structures mate with the same first slot-like structure. The at least two of the plurality of first columnar structures have the same height and are equidistant from the rotation center of the rotating member. For example, the at least two first columnar structures include a fourth boss and a tenth boss, both of which mate with the ninth drive slot and are equidistant from the rotation center of the rotating member.

[0247] Optionally, the rotating member 3 includes a rotating body 38 and a cantilever 39, the rotation center of the rotating member 3 is set on the rotating body 38; the cantilever 39 is set on the outside of the rotating body 38; part of the first active part is set on the rotating body 38, and part of the first active part is set on the cantilever 39.

[0248] The rotating body 38 is circular, with the cantilever 39 positioned outside the circle and coplanar with it. This can be understood as a portion of the outer circumference of the circle protruding outward to form the cantilever 39. The provision of the cantilever 39, with a portion of the first active portion positioned on the cantilever 39, not only meets the required distance between the first active portion and the rotation center of the rotating member 3, but also reduces the size and cost of the rotating member 3.

[0249] Optionally, there are multiple cantilevers 39, and each cantilever 39 is provided with at least one first active portion. Figure 11 As shown, there are two cantilevers 39 , and each of the two cantilevers 39 is provided with a first active part, which can not only meet the distance requirement between the first active parts provided on the cantilevers 39 , but also reduce the material consumption of the rotating part 3 .

[0250] Optionally, there are multiple cantilevers 39 , and the lengths of the multiple cantilevers 39 are equal or unequal.

[0251] By setting the length of the cantilever 39 to be equal, the distance between the first active part provided on the cantilever 39 and the rotation center of the rotating member 3 can be changed. Figure 11 As shown, the two cantilever arms 39 are of equal length.

[0252] Optionally, the driven member further includes a second driven member. When the first driven member is the first connecting rod 1 , the second driven member is the second connecting rod 2 . When the first driven member is the second connecting rod 2 , the second driven member is the first connecting rod 1 .

[0253] The second driven member includes multiple second driven portions. The surface of the rotating member 3 also includes a second surface 307, which is disposed opposite the first surface 306. The second surface 307 is provided with multiple second active portions, which are configured to cooperate with the second driven portions to drive the second driven member to move. At least two of the multiple second active portions are sequentially arranged along the circumference of the rotating member 3, thereby optimizing the layout of the multiple second active portions and reducing the size of the rotating member 3. For example, the multiple second active portions include a third boss 33 and a fifth boss 35, which are sequentially arranged along the circumference of the rotating member 3.

[0254] Optionally, at least one of the plurality of first active portions corresponds to the second active portion, such as Figure 12There are two second active parts shown, which correspond to the two first active parts respectively. Corresponding means that they are at the same distance from the rotation center of the rotating member 3 and are located in the same radial direction of the rotating member 3. The second boss 32 in the first active part corresponds to the third boss 33 in the second active part. When the air guide plate 1002 is in the closed position, the second boss 32 is located in the second drive groove 12, and the third boss 33 is located in the third drive groove 21. When the air guide plate 1002 starts to move from the closed position, the second boss 32 slides relative to the second drive groove 12 to provide driving force for the first connecting rod 1, and the third boss 33 is located in the third drive groove 21. The third boss 33 slides relative to the third drive groove 21 to provide driving force for the second connecting rod 2, so that when the air guide plate 1002 starts to move from the closed position, the first connecting rod 1 and the second connecting rod 2 can move synchronously and the travel difference of the movement is small. The air guide plate 1002 extends first to avoid a large formation difference between the first connecting rod 1 and the second connecting rod 2 at the beginning, which causes the air guide plate 1002 to rotate prematurely and interfere with the shell 1001.

[0255] The first active part and the corresponding second active part have the same height, so when the corresponding first active part and the second active part drive the first driven part and the second driven part respectively, the forces exerted on them by the first driven part and the second driven part are roughly equal, so that the rotating part 3 can rotate smoothly.

[0256] Optionally, the driving device includes a driven member, a rotating member 3, a first sliding column and a first sliding groove. The driven member is configured to be movably connected to the air guide plate 1002, and the driven member includes a first connecting rod 1 and a second connecting rod 2; the rotating member 3 rotates in a controlled manner; the first sliding column and the first sliding groove, one of which is provided on the driven member and the other is provided on the rotating member 3; the first sliding column is located in the first sliding groove and can slide relative to the first sliding groove, driving the driven member to move, so as to drive the air guide plate 1002 to move from the second position to the fourth position; wherein the first sliding groove is arc-shaped, for example, circular arc-shaped. The arc-shaped groove has a simple molding process, and the cooperation between the arc-shaped groove and the first sliding column can greatly simplify the movement trajectory of the driven member. During the opening process of the air guide plate 1002, the position of the driven part changes, and the position of the rotation center of the rotating part 3 remains unchanged. Therefore, when the air guide plate 1002 is in different positions, the position of the first sliding groove relative to the rotation center of the rotating part 3 will change. When determining whether the center of the circle where the first sliding groove is located coincides with the rotation center of the rotating part 3, it is necessary to define the position of the air guide plate 1002.

[0257] The first sliding groove may be the ninth driving groove 14 , and correspondingly, the first sliding post may be the fourth protruding post 34 .

[0258] Optionally, when the air guide plate 1002 moves from the second position to the fourth position, the center of the circle where the first sliding groove is located is the rotation center of the rotating member 3. In this case, the first sliding groove is provided on the first connecting rod 1.

[0259] Optionally, the driving device also includes: a second sliding column and a second sliding groove, one of the second sliding column and the second sliding groove is provided on the driven part, and the other is provided on the rotating part 3; during the movement of the air guide plate 1002 from the second position to the fourth position, the second sliding column is located in the second sliding groove and can slide relative to the second sliding groove to drive the driven part to move; wherein, the second sliding groove is an arc-shaped groove, and the center of the circle of the second sliding groove is the rotation center of the rotating part 3 during the movement of the air guide plate 1002 from the second position to the fourth position.

[0260] The second sliding groove may be the eleventh driving groove 16 , and the second sliding post may be the second protruding post 32 .

[0261] Optionally, when the air guide plate 1002 moves from the sixth position to the fourth position, the second sliding column disengages from the second sliding groove to avoid the second sliding groove being too long, wherein the air guide plate 1002 passes through the second position, the sixth position, the fifth position and the fourth position in sequence during the opening process; and / or the radius of the circle where the first sliding groove is located is not equal to the radius of the circle where the second sliding groove is located, for example, the radius of the circle where the first sliding groove is located is smaller than the radius of the circle where the second sliding groove is located; and / or in the process of the air guide plate 1002 moving from the second position to the fourth position, the first sliding groove and the second sliding groove are arranged on opposite sides of the rotation center of the rotating part 3, and the first sliding groove and the second sliding groove are arranged in sequence along the length direction of the driven part.

[0262] Optionally, when the air guide plate 1002 moves from the second position to the fourth position, the center of the circle where the first sliding groove is located deviates from the rotation center of the rotating member 3. At this time, the first sliding groove is located at the second connecting rod 2.

[0263] The first sliding groove is the thirteenth driving groove 24 , and the first sliding post is the fifth protruding post 35 .

[0264] The driving device also includes a fourth sliding column and a fourth sliding groove. The fourth sliding column is arranged on the driven part or rotating part 3 where the first sliding column is located; the fourth sliding groove is arranged on the driven part or rotating part 3 where the first sliding groove is located; during the process of the air guide plate 1002 moving from the second position to the fourth position, the fourth sliding column is located in the fourth sliding groove and can slide relative to the fourth sliding groove to drive the driven part to move; wherein, the first sliding groove and the fourth sliding groove are both arc-shaped and the circles they are in are concentric circles.

[0265] At this time, the fourth sliding groove is the tenth driving groove 22 , and the fourth sliding post is the third protruding post 33 .

[0266] During the opening process of the air guide plate 1002, it passes through the first position, the third position, the second position, the fifth position and the fourth position in sequence. The first position is the closed position, the third position is the cooling flat blowing position, the second position is the maximum air supply position, the fifth position is the surrounding air supply position, and the fourth position is the heating down blowing position. Alternatively, the third position is the heating down blowing position and the fourth position is the cooling flat blowing position. In the accompanying drawings, the third position is the cooling flat blowing position and the fourth position is the heating down blowing position. Figure 2 As shown, when the air guide plate 1002 starts to move from the closed position, the first boss 31 is located in the first driving groove 11, the second boss 32 is located in the second driving groove 12, and the fourth boss 34 is located in the fourth driving groove 13, so as to jointly drive the first connecting rod 1 to move. Figure 3 As shown, the third protrusion 33 is located in the third driving groove 21 and slides along the first direction, as shown in FIG. Figure 13 and 14 As shown, before reaching the third position, the first boss 31 is out of the first driving groove 11, the second boss 32 is still located in the second driving groove 12, the fourth boss 34 is still located in the fourth driving groove 13, and the fifth boss 35 slides into the fifth driving groove 23 until the air guide plate 1002 moves to the third position. Figure 33 As shown, in the third position, the third protrusion 33 reaches the first end 211. Then the wind deflector 1002 continues to open, and the third protrusion 33 moves along the second direction. When it reaches the second position, as shown in FIG. Figure 15 and 16 As shown, the second boss 32 slides into the eleventh driving groove 16, the fourth boss 34 escapes from the fourth driving groove 13 and slides into the ninth driving groove 14, the third boss 33 slides into the tenth driving groove 22, and the fifth boss 35 slides into the thirteenth driving groove 24. Figures 17 to 20 As shown, as the air guide plate 1002 continues to open, the first protruding column 31 and the second protruding column 32 successively pass through the passing-through notch 131 .

[0267] Example 2:

[0268] The difference from the first embodiment is that Figures 23 to 40 As shown, the first driving groove 11 is a straight groove and the second driving groove 12 is a curved groove. The first driving groove 11 intersects with the second driving groove 12, so that the space of the first connecting rod 1 or the rotating member 3 where the first driving groove 11 and the second driving groove 12 are located can be fully utilized to avoid the first connecting rod 1 or the rotating member 3 from being too large.

[0269] Alternatively, as Figure 30As shown, the first groove structure also includes a ninth driving groove 14. During the process of the air guide plate 1002 opening from the second position to the fourth position, the fourth boss 34 is arranged in the ninth driving groove 14 and can slide relative to the ninth driving groove 14; wherein, the ninth driving groove 14 is an arc-shaped groove, and the center of the circle where the arc-shaped groove is located during the process of the air guide plate 1002 moving from the second position to the fourth position is the rotation center of the rotating part 3.

[0270] The fourth protrusion 34 matches the size of the ninth driving slot 14 .

[0271] like Figure 34 As shown, when the air guide plate 1002 continues to open from the second position, the fourth boss 34 slides from the fourth drive groove 13 into the ninth drive groove 14 and slides relative to the ninth drive groove 14, the first boss 31 disengages from the first drive groove 11, and the second boss 32 also disengages from the second drive groove 12. The ninth drive groove 14 is an arc-shaped groove, and the center of the ninth drive groove 14 is the rotation center of the rotating member 3. Therefore, when the air guide plate 1002 continues to open from the second position, the rotating member 3 rotates, the fourth boss 34 rotates around the rotation center of the rotating member 3 relative to the ninth drive groove 14, and the first connecting rod 1 is stationary.

[0272] Optionally, when the first groove structure is provided on the first connecting rod 1, the first driving groove 11 and the ninth driving groove 14 are arranged in sequence along the length direction of the second connecting rod 2 and / or the second driving groove 12 and the ninth driving groove 14 are arranged in sequence along the length direction of the second connecting rod 2.

[0273] This arrangement ensures that, in the initial stage of opening the air deflector 1002, the first protrusion 31 engages with the first drive groove 11 and the second protrusion 32 engages with the second drive groove 12. As the air deflector 1002 opens, the second connecting rod 2 extends outward from the air outlet, whereupon the first protrusion 31 disengages from the first drive groove 11, the second protrusion 32 disengages from the second drive groove 12, and the fourth protrusion 34 enters and engages with the ninth drive groove 14, thereby meeting the requirements for the motion trajectory of the second connecting rod 2. This arrangement can also reduce the width dimension of the second connecting rod 2.

[0274] Alternatively, as Figure 16 As shown, the first groove structure also includes an eleventh drive groove 16. During the process of the air guide plate 1002 opening from the second position to the fourth position, the second boss 32 slides into the eleventh drive groove 16 and can slide relative to the eleventh drive groove 16; wherein, during the process of the air guide plate 1002 moving from the second position to the fourth position, the eleventh drive groove 16 is an arc-shaped groove whose center is located at the rotation center of the rotating part 3 and intersects with the second drive groove 12.

[0275] The second protrusion 32 matches the size of the eleventh driving groove 16 .

[0276] During the process of the air guide plate 1002 opening from the second position to the fourth position, the second boss 32 slides from the second drive groove 12 into the eleventh drive groove 16, and is at least partially formed in the eleventh drive groove 16, and the fourth boss 34 is always located in the ninth drive groove 14, so that the second boss 32 and the second drive groove 12 are matched, the fourth boss 34 and the ninth drive groove 14 are matched, and the center of the eleventh drive groove 16 and the ninth drive groove 14 are the same, so as to enhance the stability of the movement of the second connecting rod 2 while realizing the circular motion trajectory of the second connecting rod 2.

[0277] The eleventh driving groove 16 intersects with the second driving groove 12 to enhance the integration of the first connecting rod 1 or the rotating member 3 provided with the eleventh driving groove 16 and the second driving groove 12 and reduce the size of the first connecting rod 1 or the rotating member 3.

[0278] Alternatively, as Figure 29 As shown, the second groove structure includes a third drive groove 21 and a fifth drive groove 23; the second protrusion structure includes a third boss 33 and a fifth boss 35; in the process of the air guide plate 1002 opening from the first position to the second position, the third boss 33 is arranged in the third drive groove 21 and can slide relative to the third drive groove 21, and the fifth boss 35 is arranged in the fifth drive groove 23 and can slide relative to the fifth drive groove 23; wherein, the third drive groove 21 and the fifth drive groove 23 are both straight grooves.

[0279] The third protrusion 33 is adapted to the size of the third driving slot 21 . The fifth protrusion 35 is adapted to the size of the fifth driving slot 23 .

[0280] The cooperation between the third boss 33 and the third drive slot 21, and the cooperation between the fifth boss 35 and the fifth drive slot 23, jointly drive the movement of the second connecting rod 2. With the cooperation of the first connecting rod 1, the wind deflector 1002 moves from the first position to the second position. During the process of opening the wind deflector 1002 from the first position to the second position, the movement trajectory of the second connecting rod 2 is a straight line. Therefore, the third drive slot 21 and the fifth drive slot 23 are designed as straight slots. This simplifies the structure of the third drive slot 21 and the fifth drive slot 23 while maintaining the movement trajectory of the second connecting rod 2.

[0281] Optionally, when the third drive groove 21 and the fifth drive groove 23 are both provided in the second connecting rod 2, the third drive groove 21 and the fifth drive groove 23 are not parallel to the length direction of the second connecting rod 2, so that when the third boss 33 cooperates with the third drive groove 21, a force can be applied to the third drive groove 21 to drive the second connecting rod 2 to move, and when the fifth boss 35 cooperates with the fifth drive groove 23, a force can be applied to the fifth drive groove 23 to drive the second connecting rod 2 to move.

[0282] The extension line of the third driving groove 21 intersects with the fifth driving groove 23 , which on the one hand satisfies the requirements for the motion trajectory of the second connecting rod 2 , and on the other hand reduces the volume occupied by the third driving groove 21 and the fifth driving groove 23 .

[0283] Optionally, the second slot structure also includes a tenth drive slot 22, which is connected to the third drive slot 21. When the air guide plate 1002 is opened from the second position to the fourth position, the third boss 33 is located in the tenth drive slot 22 and can slide relative to the tenth drive slot 22; wherein, the connection between the tenth drive slot 22 and the third drive slot 21 forms an angle, and the tenth drive slot 22 is an arc-shaped slot.

[0284] The third protrusion 33 matches the size of the tenth driving groove 22 .

[0285] When the air deflector 1002 continues to open from the second position, the third boss 33 disengages from the third driving groove 21, slides into the tenth driving groove 22, and engages with the tenth driving groove 22. The tenth driving groove 22 is an arc-shaped groove, so that the engagement of the third boss 33 and the tenth driving groove 22 can drive the second connecting rod 2 to move in an arc.

[0286] Optionally, the second slot structure also includes a thirteenth drive slot 24, which is connected to the fifth drive slot 23. When the air guide plate 1002 is opened from the second position to the fourth position, the fifth boss 35 is located in the thirteenth drive slot 24 and can slide relative to the thirteenth drive slot 24; wherein, the connection between the thirteenth drive slot 24 and the fifth drive slot 23 forms an angle, and the thirteenth drive slot 24 is an arc-shaped slot.

[0287] The fifth protrusion 35 matches the size of the thirteenth driving groove 24 .

[0288] When the air deflector 1002 continues to open from the second position, the fifth boss 35 disengages from the fifth drive slot 23, slides into the thirteenth drive slot 24, and engages with the thirteenth drive slot 24. The thirteenth drive slot 24 is an arc-shaped slot, so that the engagement of the fifth boss 35 with the thirteenth drive slot 24 can drive the second connecting rod 2 to move in an arc.

[0289] Optionally, the second protrusion structure also includes a fourteenth protrusion 37; the second groove structure also includes a fourteenth drive groove 26. During the process of the air guide plate 1002 opening from the second position to the fourth position, the fourteenth protrusion 37 is arranged in the fourteenth drive groove 26 and can slide relative to the fourteenth drive groove 26; wherein, the fourteenth drive groove 26 is arc-shaped.

[0290] The size of the fourteenth protrusion 37 matches the size of the fourteenth driving groove 26 .

[0291] When the air deflector 1002 continues to open from the second position, the fourteenth boss 37 slides into the fourteenth driving groove 26 and cooperates with the fourteenth driving groove 26. The fourteenth driving groove 26 is an arc-shaped groove, so that the cooperation between the fourteenth boss 37 and the fourteenth driving groove 26 can drive the second connecting rod 2 to move in an arc.

[0292] During the process of the air guide plate 1002 opening from the second position to the fourth position, the third boss 33 slides in the tenth drive groove 22 and relative to the tenth drive groove 22, the fifth boss 35 slides in the thirteenth drive groove 24 and relative to the thirteenth drive groove 24, and the fourteenth boss 37 slides in the fourteenth drive groove 26 and relative to the fourteenth drive groove 26, so as to jointly drive the second connecting rod 2 to perform circular motion.

[0293] When the air guide plate 1002 moves from the second position to the fourth position, the centers of the tenth driving groove 22 , the thirteenth driving groove 24 and the fourteenth driving groove 26 do not coincide with the rotation center of the rotating member 3 .

[0294] The circles where two of the tenth driving groove 22, the thirteenth driving groove 24 and the fourteenth driving groove 26 are located are concentric circles, and the extension line of the other one intersects with the concentric circle. On the premise of satisfying the motion trajectory of the second connecting rod 2, the space occupied by the tenth driving groove 22, the thirteenth driving groove 24 and the fourteenth driving groove 26 is reduced.

[0295] like Figure 29 As shown, the thirteenth driving groove 24 and the fourteenth driving groove 26 are concentric circles, the radius of the tenth driving groove 22 is smaller than the radius of the thirteenth driving groove 24 and smaller than the radius of the fourteenth driving groove 26, and the tenth driving groove 22 is located between the thirteenth driving groove 24 and the third driving groove 21.

[0296] Optionally, the second groove structure also includes a connecting groove 25, which is connected between the thirteenth drive groove 24 and the fourteenth drive groove 26, and the thirteenth drive groove 24 is provided with an insertion notch. In the process of the air guide plate 1002 opening from the first position to the second position, the fourteenth boss 37 slides into the connecting groove 25 through the insertion notch.

[0297] The fourteenth protrusion 37 is adapted to the size of the communicating groove 25 .

[0298] When the air deflector 1002 begins to move from the first position, the fourteenth protrusion 37 does not slide into the connecting groove 25. The third protrusion 33 engages the third drive groove 21, and the fifth protrusion 35 engages the fifth drive groove 23, driving the second connecting rod 2 to move. As the second connecting rod 2 moves and the rotating member 3 rotates, the fourteenth protrusion 37 slides from the penetration notch into the connecting groove 25. At this time, the third protrusion 33 remains engaged with the third drive groove 21, and the fifth protrusion 35 remains engaged with the fifth drive groove 23. This, combined with the movement of the fourteenth protrusion 37 relative to the connecting groove 25, improves the stability of the linear motion of the second connecting rod 2. Furthermore, when the air deflector 1002 begins to move from the first position, the fourteenth protrusion 37 does not slide into the connecting groove 25, which can reduce the size of the connecting groove 25, thereby reducing the size of the second connecting rod 2 or the rotating member 3 where the connecting groove 25 is located.

[0299] The tenth driving groove 22 is located between the third driving groove 21 and the communicating groove 25 .

[0300] In a specific embodiment, before the air guide plate 1002 moves to the third position, the fourteenth protrusion 37 slides into the connecting groove 25 .

[0301] Optionally, the connecting groove 25 is a curved groove to meet the requirements for the motion trajectory of the second connecting rod 2 .

[0302] The connecting groove 25 intersects with the thirteenth driving groove 24, and the centers of the connecting groove 25 and the thirteenth driving groove 24 are located on the same side of the thirteenth driving groove 24, and the centers of the fourteenth driving groove 26 and the thirteenth driving groove 24 are located on the same side of the thirteenth driving groove 24, so that the structure of the second connecting rod 2 or the rotating part 3 provided with the second groove structure is more compact, and the size of the second connecting rod 2 or the rotating part 3 is reduced.

[0316] Optionally, the driving structure further includes a third sub-driving structure, and the driving unit further includes a third sub-driving unit. During the movement of the air guide plate 1002, the third sub-driving structure always cooperates with the third sub-driving unit.

[0317] When the connecting rod includes the first connecting rod 1 but not the second connecting rod 2, the first driving structure also includes a third sub-driving structure, and the first driving unit also includes the third sub-driving unit. When the connecting rod includes the second connecting rod 2 but not the first connecting rod 1, the second driving structure includes the third sub-driving structure, and the second driving unit includes the third sub-driving unit.

[0320] Optionally, the third sub-driving structure is provided with an avoidance groove, and when the first sub-driving structure is in the escape position, the first sub-driving part passes through the avoidance groove.

[0321] The thirteenth driving groove 24 is provided with a penetration notch, which is a avoidance groove. When the air guide plate 1002 starts to move from the first position, as the air guide plate 1002 moves, the third protrusion 33 enters the third driving groove 21 from the avoidance notch 191.

[0322] The first power slot and the second power slot may be the second drive slot 12 and the eleventh drive slot 16 respectively, and the fifth drive column may be the second protruding column 32 .

[0323] The first power slot is a straight slot, and the second power slot is a curved slot. In this case, the first power slot can be the first drive slot 11, the second power slot can be the second drive slot 12, the first drive post can be the first protrusion 31, and the second drive post can be the second protrusion 32. Alternatively, the first power slot can be the third drive slot 21, the second power slot can be the fifth drive slot 23, the first drive post can be the third protrusion 33, and the second drive post can be the fifth protrusion 35.

[0324] The first power slot may be the third drive slot 21 , the second power slot may be the tenth drive slot 22 , and the fifth drive column may be the third protrusion 33 ; or, the first power slot may be the fifth drive slot 23 , the second power slot may be the thirteenth drive slot 24 , and the fifth drive column may be the fifth protrusion 35 .

[0325] The reversing groove is the fifth driving groove 23 , and the first protruding column is the fifth protruding column 35 .

[0326] Optionally, during the opening process of the air guide plate 1002, the second protruding column in the mating position first slides along the fourth direction relative to the first adapter groove, and then slides along the third direction relative to the first adapter groove; wherein, the two ends of the first adapter groove in the length direction are the third end 213 and the fourth end 214, respectively, the third direction is the direction from the third end 213 to the fourth end 214, and the fourth direction is the direction from the fourth end 214 to the third end 213.

[0327] During the opening process of the air deflector 1002, the second protruding column slides relative to the first adapter groove in the fourth direction and the third direction, respectively. This allows the first adapter groove to be reused multiple times, thereby reducing the length of the first adapter groove. The first adapter groove is the third driving groove 21, and the second protruding column is the third protruding column 33.

[0328] Optionally, when the air guide plate 1002 is in the third position, the first protruding column is located at the first end 211 , and the second protruding column is located at the third end 213 .

[0329] In this way, when the air guide plate 1002 continues to open from the third position, the first protruding column moves relative to the reversing groove toward the second end 212, that is, along the second direction, and the second protruding column 32 moves relative to the first transfer groove toward the fourth end 214, that is, along the third direction. The angle between the second direction and the third direction is an acute angle, so that the first protruding column and the second protruding column have a smaller angle (an acute angle) to the direction of the driving force of the second connecting rod 2, thereby reducing the driving force on the rotating part 3.

[0330] Optionally, the angle formed by the fourth direction and the first direction is an acute angle.

[0331] The first protruding column moves in a first direction relative to the reversing groove, and the second protruding column 32 moves in a fourth direction relative to the first switching groove. The angle formed by the fourth direction and the first direction is an acute angle, thereby reducing the driving force on the rotating member 3.

[0332] The power source for the air-conditioning air guide plate 1002 also includes a second adapter groove, which is connected to the first adapter groove and is located on one side of the first adapter groove; when the air guide plate 1002 is opened to the second position, the second protruding column slides from the first adapter groove into the second adapter groove, thereby driving the second connecting rod 2 to perform different movements, thereby changing the position of the air guide plate 1002.

[0333] The second adapter groove is the tenth driving groove 22 , and the second protruding column is the third protruding column 33 .

[0334] At least two of the plurality of first active parts are sequentially arranged along the circumference of the rotating member 3. For example, the plurality of first active parts include a first convex column 31 and a second convex column 32, which are sequentially arranged along the circumference of the rotating member 3.

[0335] Optionally, at least two of the plurality of first active portions are unequally spaced from the rotation center of the rotating member 3. For example, the plurality of first active portions include a fourth protrusion 34 and a first protrusion 31, and the distance between the fourth protrusion 34 and the rotation center of the rotating member 3 is smaller than the distance between the first protrusion 31 and the rotation center of the rotating member 3.

[0336] At least two of the multiple first active parts have unequal heights. Multiple first groove-like structures are provided to mate with first columnar structures of varying heights, and the multiple first groove-like structures intersect. Multiple first driven parts are provided to mate with first active parts of varying heights, and the multiple first driven parts have varying heights, ensuring that the first active parts are compatible with the corresponding first driven parts. When the first active part is a first columnar structure, the first driven part is a first groove-like structure, and the height of the first driven part refers to the depth of the groove depression. When the first active part is a first groove-like structure, the first driven part is a first columnar structure, and the height of the first driven part refers to the height of the column. For example, multiple first active parts include a first boss 31 and a second boss 32, the height of the first boss 31 is greater than the height of the second boss 32, the first driven part matched with the first boss is a first driving groove, and the first driven part matched with the second boss is a second driving groove, and the depth of the first driving groove 11 is greater than the depth of the second driving groove 12, so that the top end of the first boss 31 can contact the bottom wall of the first driving groove 11, and the top end of the second boss 32 can contact the bottom wall of the second driving groove 12. Since the first drive groove 11 and the second drive groove 12 intersect, the height of the first boss 31 is greater than the height of the second boss 32. In this way, when the second boss 32 slides to the intersection of the first drive groove 11 and the second drive groove 12, there is a gap between the second boss 32 and the bottom wall of the first drive groove 11, and the second boss 32 will not slide into the first drive groove 11. The movement trajectory of the second boss 32 will not be affected by the direction of the first drive groove 11, and it can ensure that the force of the first boss 31 on the first drive groove 11 is greater than the force of the second boss 32 on the second drive groove 12. The force of the first boss 31 on the first drive groove 11 is the main driving force of the first connecting rod 1.

[0337] Optionally, there are multiple cantilevers 39, and the lengths of the multiple cantilevers 39 are equal or unequal. Figure 31 As shown, there are two cantilevers 39 , and the lengths of the two cantilevers 39 are unequal, so that the rotation centers of the first active part provided on the cantilever 39 and the rotating member 3 are unequal.

[0338] Optionally, at least two of the plurality of second active portions are sequentially arranged along the circumference of the rotating member 3. For example, the plurality of second active portions include a third protrusion 33 and a fifth protrusion 35, and the third protrusion 33 and the fifth protrusion 35 are sequentially arranged along the circumference of the rotating member 3.

[0339] Optionally, at least two of the plurality of second active portions are at unequal distances from the rotation center of the rotating member 3. For example, the plurality of second active portions include a third protrusion 33 and a fifth protrusion 35, and the third protrusion 33 and the fifth protrusion 35 are at unequal distances from the rotation center of the rotating member 3.

[0340] At least two of the plurality of second active portions have unequal heights. A plurality of second driven portions are coupled to second active portions of different heights, and the plurality of second driven portions have different heights, so that the second active portions are compatible with the corresponding second driven portions. When the second active portion is a second columnar structure, the second driven portion is a second groove-shaped structure, and the height of the second driven portion refers to the depth of the groove recess; when the second active portion is a second groove-shaped structure, the second driven portion is a second columnar structure, and the height of the second driven portion refers to the height of the column. For example, the plurality of second active portions include a third protrusion 33 and a fifth protrusion 35, and the third protrusion 33 and the fifth protrusion 35 have unequal heights, and the height of the third protrusion 33 is less than the height of the fifth protrusion 35. The depth of the third drive groove 21 is less than the depth of the fifth drive groove 23. Thus, when the third protrusion 33 slides into the intersection of the third drive groove 21 and the fifth drive groove 23, the third protrusion 33 is not affected by the fifth drive groove 23 and no force is applied to the fifth drive groove 23. For another example, the plurality of second active portions include a fourteenth boss 37 and a fifth boss 35. The heights of the fourteenth boss 37 and the fifth boss 35 are not equal, and the height of the fourteenth boss 37 is less than the height of the fifth boss 35. The depth of the fourteenth driving groove 26 is equal to the depth of the connecting groove 25, and both are less than the depth of the fifth driving groove 23. In this way, when the third boss 33 slides into the intersection of the connecting groove 25 and the fifth driving groove 23, the third boss 33 is not affected by the fifth driving groove 23, and no force is exerted on the fifth driving groove 23.

[0341] There are multiple second groove-shaped structures that match the second column-shaped structures of different heights, and the multiple second groove-shaped structures intersect. At least two second column-shaped structures among the multiple second column-shaped structures match the same second groove-shaped structure.

[0342] At least two of the plurality of second columnar structures have the same height and are equidistant from the rotation center of the rotating member.

[0343] Alternatively, a clearance groove is provided at the open end of the same second trough-like structure, the clearance groove being in communication with the same second trough-like structure; at least two of the plurality of second columnar structures have different heights; one of the second columnar structures enters the same second trough-like structure through the clearance groove; and at least two of the plurality of second columnar structures are unequally spaced from the rotation center of the rotating member.

[0344] Optionally, at least one of the plurality of first active portions corresponds to the second active portion, such as Figure 31 and 32The number of the second active parts shown is three, wherein the two second active parts provided on the cantilever 39 correspond to the two first active parts provided on the cantilever 39 respectively. The first boss 31 in the first active part and the fifth boss 35 in the second active part correspond to each other. When the air guide plate 1002 is in the closed position, the first boss 31 is located in the first drive groove 11, and the fifth boss 35 is located in the fifth drive groove 23. When the air guide plate 1002 starts to move from the closed position, the first boss 31 slides relative to the first drive groove 11 to provide driving force for the first connecting rod 1, and the fifth boss 35 is located in the fifth drive groove 23. The fifth boss 35 slides relative to the fifth drive groove 23 to provide driving force for the second connecting rod 2, so that when the air guide plate 1002 starts to move from the closed position, the first connecting rod 1 and the second connecting rod 2 can move synchronously and the stroke difference of the movement is small. The air guide plate 1002 extends first to avoid a large formation difference between the first connecting rod 1 and the second connecting rod 2 at the beginning, which causes the air guide plate 1002 to rotate prematurely and interfere with the shell 1001.

[0345] The first active portion and the corresponding second active portion have the same height.

[0346] Optionally, at least one of the multiple first active parts is staggered with the second active part, which means that at least one of the multiple first active parts does not correspond to the second active part. For example, the fourteenth boss 37 in the second active part does not correspond to any of the multiple first active parts, so that the reaction force from the driven part received by the rotating part 3 is dispersed, thereby avoiding excessive concentration of force on the rotating part 3.

[0347] The drive device also includes a tenth boss 36, which is disposed on the rotating member 3 or the first connecting rod 1 where the fourth boss 34 is located. The tenth boss 36 and the fourth boss 34 are equidistant from the rotation center of the rotating member 3. The fourth and tenth bosses 34, 36 are located on the same circle centered on the rotation center of the rotating member 3. The tenth boss 36 mates with the ninth drive slot 14. When the air deflector 1002 moves from the second position to the fourth position, the fourth and tenth bosses 34, 36 successively slide into the ninth drive slot 14 and are able to slide relative to the ninth drive slot 14, thereby improving the stability of the first connecting rod 1.

[0353] Optionally, when the air guide plate 1002 moves from the sixth position to the fourth position, the second sliding column disengages from the second sliding groove to avoid the second sliding groove being too long, wherein the air guide plate 1002 passes through the second position, the sixth position, the fifth position and the fourth position in sequence during the opening process; and / or the radius of the circle where the first sliding groove is located is not equal to the radius of the circle where the second sliding groove is located, for example, the radius of the circle where the first sliding groove is located is smaller than the radius of the circle where the second sliding groove is located; and / or in the process of the air guide plate 1002 moving from the second position to the fourth position, the first sliding groove and the second sliding groove are arranged on opposite sides of the rotation center of the rotating part 3, and the first sliding groove and the second sliding groove are arranged in sequence along the length direction of the driven part.

[0354] Optionally, when the air guide plate 1002 moves from the second position to the fourth position, the center of the circle where the first sliding groove is located deviates from the rotation center of the rotating member 3. At this time, the first sliding groove is located at the second connecting rod 2.

For example, the radius of the fifth sliding groove, the radius of the fourth sliding groove, and the radius of the first sliding groove increase in sequence.

[0360] The first slot structure also includes a twelfth drive slot 17, which is connected to the first drive slot 11. When the air deflector 1002 continues to open from the second position, the first protrusion 31 slides into the twelfth drive slot 17 and is able to slide relative to the twelfth drive slot 17. During the movement of the air deflector 1002 from the second position to the fourth position, the twelfth drive slot 17 is an arc-shaped slot with its center located at the rotation center of the rotating member 3 and intersecting with the second drive slot 12.

[0361] The first and second power grooves intersect. The first and second power grooves have different depths. The drive column structure includes a third drive column and a fourth drive column, both of which are located on the connecting rod or rotating member 3. When the rotating member 3 rotates, the third drive column cooperates with the first power groove and the fourth drive column cooperates with the second power groove, driving the connecting rod to move, thereby driving the air deflector 1002 to move. The third and fourth drive columns have different heights. The first power groove is deeper than the second power groove, and the third drive column is taller than the fourth drive column, so that the third drive column fits with the first power groove and the fourth drive column fits with the second power groove. In this case, the first power groove is the twelfth drive groove 17, the second power groove is the second drive groove 12, the third drive column is the first protrusion 31, and the fourth drive column is the second protrusion 32. The depth of the twelfth drive groove 17 is the same as that of the first drive groove 11, and the bottom wall of the twelfth drive groove 17 and the bottom wall of the first drive groove 11 can both abut against the first protrusion 31. The depth of the second driving groove 12 is the same as that of the eleventh driving groove 16 , and both the bottom wall of the second driving groove 12 and the bottom wall of the eleventh driving groove 16 can abut against the second protrusion 32 .

[0362] The driving device also includes a third sliding column and a third sliding groove, one of which is provided on the driven part, and the other is provided on the rotating part 3; during the movement of the air guide plate 1002 from the second position to the fourth position, the third sliding column is located in the third sliding groove for at least part of its stroke and slides relative to the third sliding groove; wherein, the third sliding groove is an arc-shaped groove, and the center of the circle where the third sliding groove is located is the rotation center of the rotating part 3 during the movement of the air guide plate 1002 from the second position to the fourth position.

Figure 26 As shown, the fifth boss 35 is located in the fifth driving groove 23 and slides along the first direction. Before reaching the third position, the third boss 33 slides into the third driving groove 21 along the fourth direction. Figure 34As shown, in the third position, the fifth protrusion 35 is located at the first end 211, and the third protrusion 33 is located at the third end 213. Then the air guide plate 1002 continues to open, the fifth protrusion 35 slides along the second direction, the third protrusion 33 slides along the third direction, and the fourteenth protrusion 37 slides into the connecting groove 25. Figure 35 and Figure 36 As shown, when reaching the second position, the first boss 31 disengages from the first driving groove 11 and slides into the twelfth driving groove 17, the second boss 32 disengages from the second driving groove 12 and slides into the eleventh driving groove 16, the fourth boss 34 and the tenth boss 36 slide into the ninth driving groove 14 successively, the fifth boss 35 slides into the thirteenth driving groove 24, the third boss 33 slides into the tenth driving groove 22, and the fourteenth boss 37 slides into the fourteenth driving groove 26, and then the air guide plate 1002 continues to open to the fourth position, as shown in FIG. Figures 37 to 40 shown.

[0366] Example 3:

[0367] The difference from the second embodiment is that Figure 41 As shown, the end of the eleventh driving groove on the first connecting rod coincides with the twelfth driving groove. During the opening process of the air deflector, the second protrusion moves in the second driving groove, the eleventh driving groove, and the twelfth driving groove in sequence, and finally escapes from the twelfth driving groove.

[0368] like Figure 44 The distance between the fourth boss 34 and the tenth boss 36 is relatively large. Figure 32 The distance between the fourth boss 34 and the tenth boss 36 is increased. As the rotating member rotates, the fourth boss enters the ninth driving groove 14 first, and the rotating member needs to rotate a larger angle before the tenth boss enters the ninth driving groove 14, making it smoother for the tenth boss to enter the ninth driving groove.

[0369] The groove wall of the open end of the ninth drive groove is provided with a clearance groove 141, which is connected to the ninth drive groove. When the air guide plate is opened, the fourth and ninth protrusions enter the ninth drive groove through the open end of the ninth drive groove. The depth of the clearance groove is different from the depth of the ninth drive groove. The height of the fourth protrusion is different from the height of the tenth protrusion. The height of the fourth protrusion is consistent with the depth of the ninth drive groove, and the height of the tenth protrusion is consistent with the depth of the clearance groove. Figure 41 、 Figure 46 In the embodiment, the height of the fourth protrusion is greater than that of the tenth protrusion, and the depth of the ninth drive groove is greater than that of the clearance groove. During the opening of the air deflector, the fourth protrusion enters the ninth drive groove through the opening end of the ninth drive groove, and the fourth protrusion enters the ninth drive groove through the clearance groove. The provision of the clearance groove expands the size of the opening end of the ninth drive groove, allowing the tenth protrusion to smoothly enter the ninth drive groove and avoid collision with the ninth drive groove.

[0370] The ninth driving groove 14 intersects with the second driving groove 12, so that the second protrusion slides into the intersection of the second driving groove and the ninth driving groove through the second driving groove 12 ( Figure 41 When the second boss passes through the ninth driving groove, it can slide into the second driving groove again. Since the depth of the ninth driving groove 14 is greater than the depth of the second driving groove 12, the second boss does not fit in with the ninth driving groove. In this way, when the second boss passes through the ninth driving groove, there is no force or very little force between the second boss and the ninth driving groove, which does not affect the motion trajectory of the first connecting rod. The motion trajectory of the second boss during the opening of the air deflector is as follows: Figure 41 Indicated by the arrow.

[0371] At least two of the plurality of first columnar structures cooperate with the same first groove-like structure, and the at least two of the plurality of first columnar structures are unequally spaced from the rotation center of the rotating member. For example, the at least two first columnar structures are a fourth boss and a tenth boss, and the same first groove-like structure is a ninth drive groove. The ninth drive groove has a clearance groove at its open end, and the fourth and ninth bosses are unequally spaced from the rotation center of the rotating member.

[0372] Example 4:

[0373] On the basis of Example 1, Example 2 or Example 3, Figure 42 As shown, the connection portion of the first link 1 is rotatably connected to the air deflector 1002 via a first rotation axis; the second link 2 is rotatably connected to the air deflector 1002 via a second rotation axis; the rotating member 3 is driven and connected to both the first link 1 and the second link 2 to drive the air deflector 1002 to open and close; wherein, in the process of the air deflector 1002 opening from the first position to the second position, the movement of the rotation connection portion of the second link 2 with the air deflector 1002 includes linear motion (such as Figure 28 direction of N in the middle).

[0374] The component is rotatably connected to the air guide plate 1002, and the rotational connection between the component and the air guide plate 1002 is defined as follows: a first axial hole is provided on the component, and the first rotational axis is fixedly provided on the air guide plate 1002, located in the first axial hole and capable of rotating relative to the first axial hole, so that the air guide plate 1002 is rotatably connected to the component. In this case, the rotational connection between the component and the air guide plate 1002 is the first axial hole; or the air guide plate 1002 is provided with a first axial hole, the first rotational axis is fixedly provided on the component, located in the first axial hole and capable of rotating relative to the first axial hole, so that the air guide plate 1002 is rotatably connected to the component. In this case, the rotational connection between the component and the air guide plate 1002 is the first rotational axis; or the component is provided with a first axial hole, and the air guide plate 1002 is provided with a second axial hole, and the first rotational axis passes through the first axial hole and the second axial hole, so that the air guide plate 1002 is rotatably connected to the component. In this case, the rotational connection between the component and the air guide plate 1002 is the first axial hole.

[0375] During the process of the air deflector 1002 opening from the first position to the second position, the movement of the rotation connection Y between the second connecting rod 2 and the air deflector 1002 includes linear motion, such as Figure 42 and Figure 43 As shown at point E in the middle, when the rotating member 3 rotates at the same angle, the displacement of the second connecting rod 2 is greater, so that the air guide plate 1002 moves faster and responds to the user's instructions faster.

[0376] The air guide plate 1002 passes through the third position during the process of opening from the first position to the second position. The air outlet direction of the air-conditioning indoor unit 100 at the second position is different from the air outlet direction of the indoor unit 100 at the third position, that is, from the first position to the second position, the movement of the air guide plate 1002 is not only extending along the air outlet direction of the air outlet, but also rotating, so that the air outlet direction of the air outlet changes.

[0377] Optionally, during the process of the air deflector 1002 opening from the first position to the second position, the rotation connection between the second connecting rod 2 and the air deflector 1002 is along the first straight line direction (such as Figure 28 In N, such as Figure 42 、 43 The air guide plate 1002 can move in a straight line (in the direction of E), which can not only increase the movement speed of the air guide plate 1002, but also simplify the design process of the drive device.

[0378] Optionally, in the process of the air guide plate 1002 opening from the first position to the second position, the motion trajectory of the rotational connection R (i.e., the connecting part) on the first connecting rod 1 with the air guide plate 1002 includes a straight line segment trajectory and / or a curved line segment trajectory. In other words, it can include at least one of a straight line segment trajectory and a curved line segment trajectory.

[0379] When the motion trajectory of the rotation connection between the first connecting rod 1 and the wind deflector 1002 includes a straight line segment trajectory, it can be a straight line ( Figure 43 L in the middle) can also be a broken line formed by multiple connected straight lines; when the motion trajectory of the rotational connection between the first connecting rod 1 and the wind deflector 1002 includes a curved segment trajectory, the curvature radius of at least two points on the curved segment trajectory is the same or different.

[0380] Optionally, during the process of the air deflector 1002 opening from the first position to the second position, the rotation connection between the first connecting rod 1 and the air deflector 1002 is along the second straight line direction ( Figure 43 L) performs linear motion, which can increase the movement speed of the air guide plate 1002; wherein, the first linear direction and the second linear direction intersect, so that the air guide plate 1002 can rotate, thereby allowing the air guide plate 1002 to move from the first position to the second position.

[0381] Optionally, in the process of the air guide plate 1002 opening from the first position to the second position, the rotating connection between the first connecting rod 1 and the air guide plate 1002 performs linear motion along the second straight line direction and curved motion along the curved direction in turn. This motion trajectory can not only meet the requirements for the air guide position of the air guide plate 1002, but also simplify the design of the drive device.

[0382] The angle between the first straight line direction and the second straight line direction is less than or equal to 30°, and the angle between the first straight line direction and the second straight line direction is relatively small, for example, 0°, 5°, 10°, 15°, 20°, 25°, 30°, so that when the air guide plate 1002 is opened from the first position, the movement trajectories of the rotating connection between the first connecting rod 1 and the air guide plate 1002 and the rotating connection between the second connecting rod 2 and the air guide plate 1002 are parallel or approximately parallel, so that when the air guide plate 1002 starts to move from the first position, it can be extended in a straight line or with a slight rotation, avoiding interference between the air guide plate 1002 and the shell 1001 when the air guide plate 1002 rotates.

[0383] Optionally, during the process of the air deflector 1002 opening from the first position to the second position, the rotation connection between the first connecting rod 1 and the air deflector 1002 is sequentially moved along the second straight line direction ( Figure 42 O) to do straight line motion, along the curve direction ( Figure 42 P) to make a curve motion, along the direction of the third straight line ( Figure 42 The middle Q) performs linear motion, and this motion trajectory can not only meet the requirements for the wind guide position of the wind guide plate 1002, but also simplify the design of the driving device.

[0384] Optionally, the first straight line direction and the third straight line direction intersect and an included angle is greater than an included angle between the first straight line direction and the second straight line direction.

[0385] In the initial stage of opening the air deflector 1002 from the first position, the rotational connection portion of the first connecting rod 1 with the air deflector 1002 first moves along the second linear direction and then along the third linear direction. In the initial stage of opening the air deflector 1002 from the first position, the air deflector 1002 is relatively close to the housing 1001. Therefore, the air deflector 1002 needs to be extended first and then rotated, or extended while rotating at a small angle. The rotation needs to be controlled at a small angle. Therefore, the angle between the first linear direction and the second linear direction is controlled to be small. As the air deflector 1002 opens, the distance between the air deflector 1002 and the housing 1001 increases. The air deflector 1002 can rotate at a larger angle to reach the target air deflecting position as quickly as possible. Therefore, the angle between the first linear direction and the third linear direction is large.

[0386] The curved direction and the third straight direction are located on the same side of the first straight direction, so that the first connecting rod 1 and the second connecting rod 2 move smoothly, avoiding jamming during the movement of the first connecting rod 1 and the second connecting rod 2.

[0387] Optionally, in the process of opening the air deflector 1002 from the first position to the second position, as the air deflector 1002 opens, the distance between the motion trajectory of the rotational connection between the first link 1 and the air deflector 1002 and the motion trajectory of the rotational connection between the second link 2 and the air deflector 1002 increases.

[0388] In the initial stage when the wind deflector 1002 starts to open from the first position, the distance between the motion trajectory of the rotation connection between the first link 1 and the wind deflector 1002 and the motion trajectory of the rotation connection between the second link 2 and the wind deflector 1002 is small, which can avoid the wind deflector 1002 from rotating at a large angle and avoid interference between the wind deflector 1002 and the shell 1001. As the wind deflector 1002 is further opened, the distance between the motion trajectory of the rotation connection between the first link 1 and the wind deflector 1002 and the motion trajectory of the rotation connection between the second link 2 and the wind deflector 1002 gradually increases, which can make the wind deflector 1002 flip quickly to reach the target wind-guiding position as soon as possible.

[0389] Optionally, the first position is a closed position where the air guide plate 1002 closes the air outlet, and the second position is a maximum air supply position.

[0390] Optionally, the driving device further includes a guide member, which is fixed to the housing 1001 .

[0391] The connecting rod is provided with a guide portion; the guide member is provided with a guide mating portion that cooperates with the guide portion to guide the movement of the first connecting rod 1 and / or the second connecting rod 2. The guide portion includes a first guide portion 19 provided on the first connecting rod 1 and a second guide portion 28 provided on the second connecting rod 2. The guide mating portion includes a first guide mating portion 512 and a second guide mating portion 521.

[0392] The guide member is provided with a first guide matching portion 512; the first connecting rod 1 includes a first rod body 18, the rotating member 3 is drivingly connected to the first rod body 18, the first rotating axis is arranged at the connecting portion, the first rod body 18 is provided with a first guide portion 19, and the first guide portion 19 cooperates with the first guide matching portion 512 to guide the movement trajectory of the first connecting rod 1; in the process of the air guide plate 1002 opening from the first position to the second position, the movement trajectory of the first guide portion 19 is a curved trajectory, so as to cooperate with the second connecting rod 2 to realize the movement of the air guide plate 1002 between the first position and the second position.

[0393] One of the guide portion and the guide mating portion includes a guide post, and the other includes a guide slot. During the opening of the air deflector (movement from the first position to the fourth position), the rotating member rotates in a predetermined direction to drive the linkage assembly. The guide post is located within the guide slot and moves unidirectionally along the length of the guide slot relative to the guide slot, without reverse motion. During the entire closing process of the air deflector, the guide post moves unidirectionally in the reverse direction along the length of the guide slot.

[0394] In this way, when the air guide plate is opened, the motor rotates unidirectionally, driving the guide column to move unidirectionally along the length direction of the guide groove. The unidirectional rotation of the motor can simplify the control logic of the motor; when the air guide plate is closed, the motor rotates in the opposite direction, driving the guide column to move in the opposite direction along the length direction of the guide groove, and it is a unidirectional movement.

[0395] The number of guide matching parts is at least two, and the number of guide parts is not less than the number of guide matching parts. That is, the number of guide parts and guide matching parts is at least two. The number of guide grooves is at least two, and at least one guide post is provided in each guide groove.

[0396] The number of guide posts is greater than two, wherein a line connecting three of the plurality of guide posts forms a triangle. And / or the number of guide slots is greater than two, wherein a line connecting the middle portions of the length directions of three of the plurality of guide slots forms a triangle.

[0397] The connecting line of the middle parts of the three guide posts and / or the three guide grooves in the length direction forms a triangle, which can define a plane instead of being located on the same straight line, thereby guiding the connecting rod to perform planar motion.

[0398] The guide member includes a mechanism box 5, a box cover 51, a first connecting rod 1, a second connecting rod 2 and a box body 52. Figure 4 and 6 As shown, the first guide engaging portion 512 is provided on the surface of the box cover 51 facing the first connecting rod 1. One of the first guide portion 19 and the first guide engaging portion 512 is a first guide post, and the other is a first guide groove. The first guide post is located in the first guide groove and slides relative to the first guide groove. The first guide post and the first guide groove are adapted to each other. The shape of the first guide groove is the same as the motion trajectory of the first connecting rod 1 at the location of the first guide groove or the first guide post that cooperates with the first guide groove. The motion trajectory of the first connecting rod 1 is guided and further defined by the cooperation between the first guide post and the first guide groove.

[0399] The guide post includes a first guide post, and the guide slot includes a first guide slot. During the opening process of the air deflector, the first guide post is located in the first guide slot and moves unidirectionally relative to the first guide slot along the length direction of the first guide slot, thereby simplifying the motion trajectory of the first connecting rod and thus simplifying the structure of the drive device.

[0400] The first connecting rod 1 is cut with the first plane to obtain a longitudinal section of the first connecting rod 1 . The motion trajectory at different locations on the longitudinal section is different. The first plane is perpendicular to the thickness direction of the first connecting rod 1 and is the plane where the length and width directions of the first connecting rod 1 are located.

[0401] The number of the first guide matching parts is at least two, the number of the first guide parts is not less than the number of the first guide matching parts, and when the number of the first guide parts and the first guide matching parts are both greater than two, the connection line of the multiple first guide parts 19 is not located on the same straight line but forms a triangle, the connection line of three first guide matching parts in the multiple first guide matching parts is not located on the same straight line but forms a triangle, that is, the connection line of three first guide columns in the multiple first guide columns forms a triangle, and the connection line of the middle parts of the length direction of three first guide grooves in the multiple first guide grooves forms a triangle, so that the multiple first guide parts 19 can jointly guide the first connecting rod 1 to make planar motion, so that during the opening process of the air guide plate, the first rod body extends out of the air outlet while rotating in the plane where the first connecting rod is located, and the rotation center during the rotation process is not fixed.

[0402] The guide member is provided with a second guide matching portion 521 ; the second connecting rod is provided with a second guide portion 28 , and the second guide portion 28 matches with the second guide matching portion 521 to guide the motion trajectory of the second connecting rod 2 .

[0403] The second guide engaging portion 521 is provided on the surface of the box body 52 facing the second connecting rod 2. One of the second guide portion 28 and the second guide engaging portion 521 is a second guide post, and the other is a second guide slot. The second guide post is positioned within and slides relative to the second guide slot. The second guide post and the second guide slot are adapted to each other. The shape of the second guide slot is identical to the motion trajectory of the second connecting rod 2. The second guide post and the second guide slot cooperate to guide and further define the motion trajectory of the second connecting rod 2. The guide post includes a second guide post, and the guide slot includes a second guide slot.

[0404] During the opening process of the air guide plate, the second guide post is located in the second guide groove and moves unidirectionally relative to the second guide groove along the length direction of the second guide groove.

[0405] The second guide groove includes a connected straight guide section and a curved guide section. When the wind deflector is opened, the second guide column slides through the straight guide section and the curved guide section in sequence, and moves unidirectionally in both the straight guide section and the curved guide section.

[0406] The motion trajectory of each part on the second connecting rod is the same, which is translational motion. The shape of the second guide groove is the same as the motion trajectory of the second connecting rod 2. Therefore, the straight guide section is a straight track N, and the curved guide section is an arc track M.

[0407] The second connecting rod 2 is cut with the second plane to obtain a longitudinal section of the second connecting rod 2 , and the motion trajectory at each point on the longitudinal section is the same, wherein the second plane is perpendicular to the thickness direction of the second connecting rod 2 and is the plane where the length and width directions of the second connecting rod 2 are located.

[0408] The number of the second guide matching portions is at least two, and the number of the second guide portions is not less than the number of the second guide matching portions.

[0409] When the number of the second guide parts 28 and the second guide matching parts is greater than two, the connecting lines of the multiple second guide parts 28 are not located in the same straight line, and the connecting lines of the multiple second guide matching parts are not located in the same straight line. For example, the connecting lines of three of the multiple second guide parts form a triangle; the connecting lines of three of the multiple second guide matching parts form a triangle, that is, the connecting lines of the middle parts of the length direction of three of the multiple second guide grooves form a triangle, and the connecting lines of three of the multiple second guide columns form a triangle. In this way, the multiple second guide parts 28 can jointly guide the second connecting rod 2 to perform planar motion in the process of the air guide plate moving from the second position to the fourth position, wherein, when the air guide plate moves from the first position to the second position, the second connecting rod performs linear motion.

[0410] In the first embodiment, the number of the first guide post, the first guide slot, the second guide post, and the second guide slot is two. In the second embodiment, the number of the first guide post, the first guide slot, the second guide post, and the second guide slot is three.

[0411] Optionally, during the opening process of the wind deflector, the motion trajectory of the first rod body is a first curved segment trajectory, and the shape of the first guide groove is the same as the motion trajectory of the first connecting rod 1 at the position of the first guide groove or the first guide column matching the first guide groove. Therefore, the first guide groove is a curved guide groove.

[0412] The first curved segment trajectory 513 includes a first sub-curved segment trajectory 514 and a second sub-curved segment trajectory 515 sequentially connected along the length direction of the first connecting rod 1; wherein a corner W is formed at the connection between the first sub-curved segment trajectory 514 and the second sub-curved segment trajectory 515.

[0413] The curved guide groove includes a first sub-curved guide groove and a second sub-curved guide groove arranged in sequence along the length direction of the first connecting rod, and a bend is formed at the connection between the first sub-curved guide groove and the second sub-curved guide groove; the first sub-curved guide groove is the first sub-curved segment trajectory 514, and the second sub-curved guide groove is the second sub-curved segment trajectory 515.

[0414] During the opening process of the air guide plate, the first guide post slides through the first sub-curved guide groove and the second sub-curved guide groove in sequence, and moves unidirectionally in the first sub-curved guide groove and the second sub-curved guide groove.

[0415] During the opening process of the air guide plate, the first guide column starts to move relative to the first sub-curve guide groove from the end of the first sub-curve guide groove that is away from the second sub-curve guide groove, moves unidirectionally along the first sub-curve guide groove to the corner W, enters the second sub-curve guide groove, and moves unidirectionally along the second sub-curve guide groove in the direction away from the corner until it reaches the end of the second sub-curve guide groove away from the corner.

[0416] Optionally, during the process of the air deflector 1002 opening from the second position to the fourth position, the motion trajectory of the rotation connection between the second connecting rod 2 and the air deflector 1002 is an arc trajectory, for example Figure 28 Middle arc trajectory M, Figure 42 and Figure 43 The arc-shaped trajectory F can simplify the design of the driving device.

[0417] In the closed position, the first guide post is located at the end of the first sub-curved segment trajectory 514 that faces away from the second sub-curved segment trajectory 515, and the second guide post is located at the end of the straight portion of the second guide groove that faces away from the arc-shaped portion. As the air guide plate 1002 opens, the first guide post moves along the first sub-curved segment trajectory 514 toward the second sub-curved segment trajectory 515, while the second guide post moves along the straight portion and toward the arc-shaped portion. In the cooling flat-blow position, the first guide post reaches the angle, then enters the second sub-curved segment trajectory 515 and moves away from the first sub-curved segment trajectory 514. In the maximum air supply position, the first guide post enters the end of the second sub-curved segment trajectory 515 that faces away from the first sub-curved segment trajectory 514 and remains stationary. The second guide post enters the junction of the straight portion and the arc-shaped portion, then moves along the arc-shaped portion until it reaches the heating downward-blowing position.

[0418] Optionally, during the process of the air deflector 1002 opening from the second position to the fourth position, the first connecting rod 1 is stationary, and the rotation connection between the second connecting rod 2 and the air deflector 1002 rotates around the axis of the first rotation shaft.

[0419] In this way, during the process of the air guide plate 1002 opening from the second position to the fourth position, the rotating member 3 no longer needs to drive the first connecting rod 1 to move, thereby simplifying the structure of the driving device, and the rotating connection between the second connecting rod 2 and the air guide plate 1002 rotates around the axis of the first rotating shaft, and the second connecting rod 2 drives the air guide plate 1002 to flip, thereby meeting the requirements for the air guide position of the air guide plate 1002.

[0420] Optionally, the center of the circular arc trajectory M and the linear motion trajectory in the first straight direction are located on the same side of the circular arc trajectory M, so that the second connecting rod 2 rotates along the circular arc trajectory M after extending along the first straight direction.

[0421] The circumference of the arc-shaped trajectory M is smaller than the length of the linear motion trajectory in the first linear direction.

[0422] The present application also provides an air conditioner, including an indoor unit 100 , the indoor unit 100 including an air guide plate 1002 and a driving device as described in any one of the above embodiments, the first connecting rod 1 and the second connecting rod 2 are both rotatably connected to the air guide plate 1002 .
