[0077] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.
[0078] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.
[0079] Example 1:
[0080] Combine Figures 1-11 As shown, an embodiment of the present disclosure provides a driving device for an air guide plate of an air conditioner, including a driving wheel 30 , a first connecting rod 10 and a second connecting rod 20 .
[0081] The driving wheel 30 rotates in a controlled manner, and includes a first tooth portion 301 and a second tooth portion 302; the first connecting rod 10 includes a first rack 101, which is used to engage with the first tooth portion 301 and be connected to the wind guide plate 70, for example, directly rotatingly connected to the wind guide plate 70 through a first rotating shaft 501; the second connecting rod 20 includes a second rack 201, which is used to engage with the second tooth portion 302 and be connected to the wind guide plate 70, for example, directly rotatingly connected to the wind guide plate 70 through a second rotating shaft 502.
[0082] The driving wheel 30 rotates, driving the first connecting rod 10 and the second connecting rod 20 to move, thereby driving the air guide plate 70 to move, thereby realizing the opening and closing of the air guide plate 70.
[0083] The first connecting rod 10 is an integral structure, directly rotatably connected to the air deflector 70 via a first rotating shaft 501, with no other connecting rod 109 connected between the first connecting rod 10 and the air deflector 70. The second connecting rod 20 is an integral structure, directly rotatably connected to the air deflector 70 via a second rotating shaft 502, with no other connecting rod 109 connected between the second connecting rod 20 and the air deflector 70. Furthermore, both the first connecting rod 10 and the second connecting rod 20 are rotatably connected to the air deflector 70, rather than slidingly connected, thereby preventing wear on the first connecting rod 10 and the second connecting rod 20 during sliding.
[0084] Alternatively, as Figure 9a and Figure 9b As shown, the first tooth portion 301 and the second tooth portion 302 are coaxially arranged and rotate synchronously.
[0085] The rotation axes of the first tooth portion 301 and the second tooth portion 302 coincide and rotate synchronously with each other at the same angular velocity. This simplifies the control of the movement of the first connecting rod 10 and the second connecting rod 20 on the one hand, and the first tooth portion 301 and the second tooth portion 302 can be driven by a motor 407 on the other hand.
[0086] Optionally, the first tooth portion 301 is a non-circular gear, and the second tooth portion 302 is a cylindrical gear.
[0087] This arrangement enables the first connecting rod 10 and the second connecting rod 20 to have different movement speeds and trajectories during the movement process, thereby realizing the complex movement of the air guide plate 70 and better meeting the diverse needs of air conditioning air guidance.
[0088] Through the special shape and transmission characteristics of the non-circular gear, more precise speed control and position adjustment can be achieved during the movement of the air guide plate 70, making the air guiding effect of the air conditioner more ideal and improving user comfort.
[0089] Optionally, the drive device for the air deflector further includes a reduction wheel 40, which is connected between the motor 407 and the drive wheel 30. The motor 407 is in driving connection with the reduction wheel, which meshes with the cylindrical gear, which is fixedly connected to the non-circular gear. Motor 407 drives the reduction wheel to rotate, which in turn drives the cylindrical gear, and the non-circular gear rotates with the cylindrical gear.
[0090] The reduction gear 40 is a cylindrical gear and the radius of the reduction gear is smaller than the radius of the second tooth portion 302 .
[0091] Alternatively, as Figure 40 and Figure 41 As shown, during the opening process of the air deflector 70, the motion trajectory of the first rotating shaft 501 includes the first trajectory segment A1A2 and the second trajectory segment A2A3, and the motion trajectory of the second rotating shaft 502 includes the third trajectory segment B1B2 and the fourth trajectory segment B2B3. The first trajectory segment A1A2 corresponds to the third trajectory segment B1B2, that is, during the movement of the air deflector 70, when the first rotating shaft 501 moves along A1A2, the second rotating shaft 502 moves along B1B2, and the second trajectory segment A2A3 corresponds to the fourth trajectory segment B2B3. Correspondingly, that is, during the movement of the air guide plate 70, when the first rotating axis 501 moves along A2A3, the second rotating axis 502 moves along B2B3; wherein, at least one of the first trajectory segment A1A2, the second trajectory segment A2A3, the third trajectory segment B1B2 and the fourth trajectory segment B2B3 is a non-circular curve, so that there is deflection during the movement of the first connecting rod 10 and / or the second connecting rod 20, so that the air guide plate 70 can achieve a complex movement mode and better adapt to the shape and air guide requirements of the air-conditioning outlet 404.
[0092] Optionally, the first track segment A1A2 and the third track segment B1B2 are both arc-shaped.
[0093] This setting can simplify the motion trajectory of the first connecting rod 10 and the second connecting rod 20, making the control logic of the driving device for the air-conditioning air guide plate simpler, facilitating precise motion control, improving the reliability and stability of the system, and also making the movement of the air guide plate 70 in the initial opening stage smoother, reducing jitter and noise during movement.
[0094] Optionally, during the process of opening the air guide plate 70 from the first position to the second position, the first rotating shaft 501 moves from A1 to A2 along the first trajectory segment A1A2, and the second rotating shaft 502 moves from B1 to B2 along the third trajectory segment B1B2; during the process of opening the air guide plate 70 from the second position to the extreme position, the first rotating shaft 501 reciprocates along the second trajectory segment A2A3, and at the extreme position, the first rotating shaft is located at point A2, and the second rotating shaft 502 moves from B2 to B3 along the fourth trajectory segment B2B3.
[0095] There may be a fourth position between the first position and the second position, and a fifth position between the second position and the limit position. The wind deflector 70 passes through the first position, the fourth position, the second position, the fifth position and the limit position in sequence during the opening process. Figures 1 to 30 As shown, the first position is the closed position, the fourth position is the cooling horizontal blowing position, the second position is the maximum air supply position, the fifth position is the surrounding air supply position, and the extreme position is the heating downward blowing position. Alternatively, the fourth position is the heating downward blowing position, and the extreme position is the cooling horizontal blowing position.
[0096] When the air deflector 70 opens from the second position to the extreme position, the first rotation axis 501 reciprocates along the second trajectory segment A2A3. This reciprocating motion effectively reduces the space occupied by the first connecting rod 10 during its movement. Compared to a traditional unidirectional motion trajectory, the reciprocating motion prevents the first connecting rod 10 from overstretching during movement, thereby reducing the installation space required for the air deflector drive device within the indoor unit 80.
[0097] Alternatively, as Figure 32 As shown, the fourth trajectory segment B2B3 is a non-circular curve, which cooperates with the reciprocating motion of the first rotating shaft 501 along the second trajectory segment A2A3, moving from A2 to A3, and then from A3 to A2, for one or more cycles to realize the flipping of the air guide plate 70 from the second position to the extreme position.
[0098] Optionally, when the second rotation axis 502 moves along the fourth track segment B2B3 , the second rotation axis 502 rotates and revolves around the first rotation axis 501 .
[0099] During the movement of the air deflector 70 from the second position to the extreme position, the center of rotation of the second rotation axis 502 is the position of the first rotation axis 501 corresponding to the current position of the second rotation axis 502. Correspondence means that at the same moment when the second rotation axis 502 is at position B8, the first rotation axis 501 is at position A8, where B8 is B2, B3, or a point between B2 and B3 in the second trajectory segment B2B3, and A8 is A2, A3, or a point between A2 and A3 in the second trajectory segment A2A3. During the movement of the air deflector 70, the position of the first rotation axis 501 is not fixed. Therefore, the position of the center of rotation of the second rotation axis 502 is also not fixed. In conjunction with the rotation of the second rotation axis 502, the air deflector 70 is flipped from the second position to the extreme position.
[0100] Optionally, when the second rotation axis 502 moves along the fourth track segment B2B3 , the instantaneous rotation center of the second rotation axis 502 is the position of the first rotation axis 501 corresponding to the current position of the second rotation axis 502 .
[0101] Optionally, when the second rotation axis 502 moves along the fourth track segment B2B3 , the movement tracks of various points on the second connecting rod 20 located on the same plane are different, where the plane is the longitudinal section of the second connecting rod 20 .
[0102] This arrangement allows the second connecting rod 20 to perform planar motion, that is, to move within the plane of the longitudinal section of the second connecting rod 20. Because the speeds and motion trajectories of various points on the second connecting rod 20 located in the same plane differ when the second rotating shaft 502 moves along the fourth trajectory segment B2B3, the second connecting rod 20 does not perform translational motion, but rather a combination of movement and rotation, with the instantaneous rotation center of each point located in the same plane constantly changing. This, in conjunction with the movement of the first rotating shaft 501, enables the air deflector 70 to move from the second position to the extreme position.
[0103] Alternatively, as Figure 12 and Figure 16 As shown, the second connecting rod 20 includes a third guide portion 202 and a fourth guide portion 204. During the opening process of the air guide plate 70, the third guide portion 202 reciprocates, which shortens the extension distance of the second connecting rod 20, reduces the size of the second connecting rod 20, and ensures the strength of the second connecting rod 20; the fourth guide portion 204 moves unidirectionally.
[0104] The fourth guide portion 204 performs unidirectional motion, and the third guide portion 202 performs reciprocating motion in its motion trajectory. Through the reciprocating motion of the third guide portion 202 and the unidirectional motion of the fourth guide portion 204, the second connecting rod 20 can achieve a complex motion trajectory, thereby enabling the air guide plate 70 to achieve a complex motion mode during the opening process, thereby meeting the diverse requirements of the air conditioner for air guide direction and angle under different working conditions.
[0105] Optionally, the third guide portion 202 is located between the fourth guide portion 204 and the second rotating shaft 502, and the motion trajectory of the second rotating shaft 502, the motion trajectory of the third guide portion 202, and the motion trajectory of the fourth guide portion 204 are jointly realized to meet the motion requirements of the air guide plate 70.
[0106] Optionally, when the air guide plate 70 opens from the first position to the second position, the third guide portion 202 and the fourth guide portion 204 both perform unidirectional movement.
[0107] When the air deflector 70 opens from the first position (closed position) to the second position (maximum air supply position), the third guide portion 202 and the fourth guide portion 204 both move unidirectionally. This design simplifies the motion control logic of the first and second connecting rods 10, facilitates precise motion control, and reduces the complexity of the control system.
[0108] Optionally, during the process of opening the air guide plate 70 from the first position to the second position, the movement trajectories of the third guide portion 202 and the fourth guide portion 204 are the same, wherein the same movement trajectories mean that the movement trajectories can completely overlap after translation, making the movement of the air guide plate 70 more stable and consistent, avoiding jitter and jamming during movement, and improving the uniformity and reliability of air guidance.
[0109] Optionally, during the process of the air guide plate 70 opening from the second position to the extreme position, the fourth guide portion 204 and the second rotating shaft 502 have reverse movement or movement with an opposite movement trend, or there is a moment at which the angle between the fourth guide portion 204 and the movement direction of the second rotating shaft 502 is greater than 90°, so that the second connecting rod 20 can deflect at a large angle instead of moving horizontally, thereby enabling the air guide plate 70 to be flipped when the stroke of the second connecting rod 20 is small, so that the air guide plate 70 is switched from the second position to the extreme position.
[0110] Optionally, during the process of opening the air guide plate 70 from the second position to the extreme position, the movement trajectories of the third guide portion 202 and the fourth guide portion 204 are different, so that the second connecting rod 20 can be deflected instead of translated, thereby realizing the switching of the air guide plate 70 from the second position to the extreme position.
[0111] like Figures 1 to 6 As shown, the drive device for the air deflector of an air conditioner further includes a mechanism box 6, which includes a first box cover 61 and a second box cover 62 that are arranged opposite and assembled. The first box cover 61 and the second box cover 62 together define a storage space, and the first connecting rod 10, the second connecting rod 20, the driving wheel 30, and the reduction wheel are collectively located in the storage space. The first connecting rod 10 and the second connecting rod 20 are arranged in sequence along the direction from the first box cover 61 to the second box cover 62.
[0112] The second box cover 62 includes a third guide matching portion 621 , which cooperates with the third guide portion 202 to guide the movement trajectory of the second connecting rod 20 to drive the air guide plate 70 to move along a set trajectory.
[0113] The second box cover 62 further includes a fourth guide fitting portion 625 , which fits with the fourth guide portion 204 , and the third guide fitting portion 621 fits with the third guide portion 202 to jointly guide the motion trajectory of the second connecting rod 20 .
[0114] like Figure 4As shown, one of the third guide matching part 621 and the third guide part 202 is the third guide groove 622, and the other is the third guide column 203. The third guide column 203 is adapted to the third guide groove 622, and the third guide column 203 is located in the third guide groove 622 and can slide relative to the third guide groove 622; one of the fourth guide matching part 625 and the fourth guide part 204 is the fourth guide groove 626, and the other is the fourth guide column 205. The fourth guide column 205 is adapted to the fourth guide groove 626, and the fourth guide column 205 is located in the fourth guide groove 626 and can slide relative to the fourth guide groove 626.
[0115] In the process of the air guide plate 70 opening from the first position to the second position, the movement direction of the second rotating shaft 502, the movement direction of the third guide part 202, and the movement direction of the fourth guide part 204 are all the same, and the movement trajectory of the second rotating shaft 502, the movement trajectory of the third guide part 202, and the movement trajectory of the fourth guide part 204 are all the same, that is, after translation, the movement trajectory of the second rotating shaft 502, the movement trajectory of the third guide part 202, and the movement trajectory of the fourth guide part 204 can overlap.
[0116] The third guide groove 622 includes a first sub-guide groove 623 and a second sub-guide groove 624 which are sequentially arranged and connected along the length direction of the third guide groove 622. During the process of the air guide plate 70 opening from the first position to the extreme position, the third guide column 203 passes through the first sub-guide groove 623 and the second sub-guide groove 624 in sequence; the fourth guide groove 626 includes a third sub-guide groove 627, a fourth sub-guide groove 628 and a fifth sub-guide groove 629 which are sequentially arranged and connected along the length direction of the fourth guide groove 626. During the process of the air guide plate 70 opening from the first position to the extreme position, the fourth guide column 205 passes through the third sub-guide groove 627, the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence.
[0117] like Figure 40 and Figure 41 As shown, in the process of the air guide plate 70 opening from the first position to the second position, the movement trajectory of the second rotating shaft 502 is B1B2, which is an arc shape, and the third guide column 203 is located in the first sub-guide groove 623 and can slide unidirectionally relative to the first sub-guide groove 623, and the fourth guide column 205 is located in the third sub-guide groove 627 and can slide unidirectionally relative to the third sub-guide groove 627, that is, the third guide column 203 cooperates with the first sub-guide groove 623, and the fourth guide column 205 cooperates with the third sub-guide groove 627. The first sub-guide groove 623 and the third sub-guide groove 627 are both arc-shaped, and the shape is the same as B1B2. The first sub-guide groove 623, the third sub-guide groove 627 and B1B2 can be different arc segments on the same circle or located on concentric circles.
[0118] like Figure 40 and Figure 41 As shown, in the process of the air guide plate 70 opening from the second position to the extreme position, the movement trajectory of the second rotating shaft 502 is B2B3, which is a non-circular arc shape, and the third guide column 203 is located in the second sub-guide groove 624 and can reciprocate relative to the second sub-guide groove 624 along the length direction of the second sub-guide groove 624, and the fourth guide column 205 is located in the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence and can slide unidirectionally relative to the fourth sub-guide groove 628 and the fifth sub-guide groove 629, that is, the third guide column 203 cooperates with the second sub-guide groove 624, and the fourth guide column 205 cooperates with the fourth sub-guide groove 628 and the fifth sub-guide groove 629 in sequence. When the fourth guide column 205 cooperates with the fourth sub-guide groove 628, the fourth guide column 205 and the second rotating shaft 502 have reverse movement, and when the fourth guide column 205 cooperates with the low-speed sub-guide groove, the fourth guide column 205 and the second rotating shaft 502 have the same direction movement. The second sub-guide groove 624 can be arc-shaped. In this case, the second sub-guide groove 624 and the first sub-guide groove 623 are located on the same circle or on different circles. The fourth sub-guide groove 628 and the fifth sub-guide groove 629 can be arc-shaped or not. The fourth sub-guide groove 628 and the fifth sub-guide groove 629 are both located on the same side of the third sub-guide groove 627.
[0119] like Figure 10 and Figure 11 As shown, the second connecting rod 20 includes a second tooth segment 207 for meshing with the second tooth portion 302. The pitch line of the second tooth segment 207 is a non-circular curve, so that the rotation center of the second connecting rod 20 is not a fixed point during the meshing of the second tooth portion 302 and the second tooth segment 207. During the meshing of the second tooth portion 302 and the second tooth segment 207, the wind deflector 70 moves from the second position to the extreme position, and the corresponding motion trajectory of the second rotation axis 502 is a non-circular trajectory B2B3.
[0120] The non-circular pitch curve of the second tooth segment 207 enables the air deflector 70 to move in a variety of complex motion paths. This design overcomes the limitations of traditional circular arc gear transmissions, making the air deflector 70 more flexible and diverse in motion, better adapting to the needs of the air conditioner in different operating modes.
[0121] The pitch line design of the second tooth segment 207 eliminates a fixed center of rotation for the second connecting rod 20 during movement. This dynamic center of rotation design enables more complex movement patterns. For example, during the opening of the air deflector 70, the second connecting rod 20 can be adjusted in multiple directions as needed to achieve a more ideal air supply effect.
[0122] Optionally, the nodal line of the second tooth segment 207 satisfies the following: when the second tooth portion 302 is engaged with the second tooth segment 207, the velocities and angular velocities of each point on the same plane of the second connecting rod 20 are different, wherein the plane is the longitudinal section of the second connecting rod 20, so that the second connecting rod 20 does not perform translational motion but deflects, so as to realize multiple wind-guiding positions of the wind guide plate 70.
[0123] Optionally, the nodal line of the second tooth segment 207 satisfies: when the second tooth portion 302 is engaged with the second tooth segment 207, the motion trajectories of the points on the second connecting rod 20 located on the same plane are different, wherein the plane is the longitudinal section of the second connecting rod 20, so that the second connecting rod 20 does not perform translational motion but deflects, so as to realize multiple wind-guiding positions of the wind guide plate 70.
[0124] Optionally, the pitch line of the second tooth segment 207 satisfies: when the second tooth portion 302 is engaged with the second tooth segment 207 , during the opening of the air guide plate 70 , the third guide portion 202 reciprocates and the fourth guide portion 204 moves unidirectionally.
[0125] The pitch line of the second tooth segment 207 satisfies the following conditions: during the meshing of the second tooth portion 302 and the second tooth segment 207, the second rotation axis 502 and the fourth guide portion 204 move in opposite directions. The pitch line of the second tooth segment 207 satisfies the following conditions: during the meshing of the second tooth portion 302 and the second tooth segment 207, the second rotation axis 502 and the fourth guide portion 204 move in the same direction.
[0126] Optionally, the second connecting rod 20 further includes a first tooth segment 206 for meshing with the second tooth portion 302 . The first tooth segment 206 and the second tooth segment 207 are sequentially arranged along the length direction of the second connecting rod 20 . The pitch line D5D6 of the first tooth segment 206 is an arc shape.
[0127] In this way, when the second tooth portion 302 is meshed with the first tooth segment 206 , the motion trajectory of the second rotating shaft 502 is a circular arc trajectory B1B2 .
[0128] During the opening process of the air deflector 70, the second tooth portion 302 sequentially meshes with the first tooth segment 206 and the second tooth segment 207. During the meshing process of the second tooth portion 302 and the first tooth segment 206, the air deflector 70 moves from the first position to the second position.
[0129] Optionally, the pitch line of the first tooth segment 206 satisfies that, during the process of meshing of the second tooth portion 302 with the first tooth segment 206 , the motion trajectories of the third guide portion 202 and the fourth guide portion 204 are the same.
[0130] The first box cover 61 is provided with a first guide matching portion 611 and a second guide matching portion 632, and the first connecting rod 10 includes a first guide portion 102 and a second guide portion 123. One of the first guide portion 102 and the first guide matching portion 611 is a first guide groove 612, and the other is a first guide column 103. The first guide column 103 is adapted to the first guide groove 612. The first guide column 103 is located in the first guide groove 612 and can slide relative to the first guide groove 612. One of the second guide portion 123 and the second guide matching portion 632 is a second guide groove 633, and the other is a second guide column 124. The second guide column 124 is adapted to the second guide groove 633. The second guide column 124 is located in the second guide groove 633 and can slide relative to the second guide groove 633, so as to jointly guide the movement trajectory of the first connecting rod 10.
[0131] When the first rotating shaft 501 moves along the first track segment A1A2, the first guide column moves unidirectionally in the first guide groove, and the second guide column 124 moves unidirectionally in the second guide groove 633; when the first rotating shaft 501 reciprocates along the second track segment A2A3, the first guide column moves reciprocatingly in the first guide groove, and the second guide column 124 moves reciprocatingly in the second guide groove 633612.
[0132] like Figure 40 and Figure 41 As shown, in the closed position of the air guide plate 70, the first rotation axis 501 is located at point A1, and the second rotation axis 502 is located at point B1. A1A2 and A2A3 are both arc-shaped, with the center of the arc being A0. B1B2 is also an arc-shaped, with the center being B0. The rotation center (or center) of the pitch line D5D6 of the first tooth segment 206 is B0. Figure 31 As shown, the pitch line of the second tooth portion 302 is the circle E1, the pitch line of the first tooth portion 301 is the non-circular curve C5C6, the pitch lines of the second rack 201 include D5D6, and the non-circular curve C5C7 is the pitch line of the first rack 101.
[0133] The C5C7 curve corresponds to A1A2, which is not an arc; the first link performs rotational motion during the C5C7 process, not translational motion.
[0134] D5D6 corresponds to the process of the second rotation axis moving along B1B2 and is in an arc shape.
[0135] The circle E1 is concentric with the non-circular curve C5C6, and the center of rotation is E.
[0136] In the present application, the extension and rotation of the air guide plate 70 are achieved by using the different displacement differences between the first rotating shaft 501 and the second rotating shaft 502 .
[0137] The air guide plate 70 changes from the closed position to the cooling flat blowing position to the maximum air supply position:
[0138] The first rotating shaft 501 moves from A1 along the arc A1A2 to A2; the second rotating shaft 502 moves from B1 along the arc B1B2 to B2, and the second tooth portion 302 engages with the first tooth segment 206. That is, the first rotating shaft 501 rotates around A0, and the second rotating shaft 502 rotates around B0, and the distance between the first rotating shaft 501 and the second rotating shaft 502 does not change during the movement.
[0139] The air guide plate 70 changes from the maximum air supply position → the surrounding air supply position → the heating downward blowing position:
[0140] The first rotating shaft 501 starts from A2 and moves back and forth on A2A3, and finally moves to A2; the second tooth portion 302 engages with the second tooth segment 207, and the second rotating shaft 502 starts from B2 and moves along the curve B2B3 to B3, wherein the curve B2B3 is not a circular arc, and its instantaneous rotation center is the first rotating shaft 501 corresponding to the second rotating shaft.
[0141] Optionally, during the movement of the air guide plate 70 , a constraint relationship exists between the transmission ratio i between the first tooth portion 301 and the first rack 101 and the angular velocity ωA of the first rotating shaft 501 and the angular velocity ωB of the second rotating shaft 502 .
[0142] During the movement of the air deflector 70, the length of the line connecting the first rotating shaft 501 and the second rotating shaft 502 remains unchanged. In this way, when the first rotating shaft 501 and the second rotating shaft 502 move on their respective trajectories, the movement speed of the first rotating shaft 501 and the movement speed of the second rotating shaft 502 must satisfy a certain functional relationship. In other words, during the movement of the air deflector 70, the transmission ratio i between the first tooth portion 301 and the first rack 101 and the angular velocity ω of the first rotating shaft 501 are A and the angular velocity ω of the second rotation axis 502 B There is a constraint relationship, so that in this application, the first connecting rod 10 and the air guide plate 70 are directly rotationally connected through the first rotating shaft 501, and the second connecting rod 20 and the air guide plate 70 are directly rotationally connected through the second rotating shaft 502.
[0143] If the first connecting rod 10 is provided with a sliding column, the air guide plate 70 is provided with a sliding groove, the sliding column is located in the sliding groove and is slidingly connected to the sliding groove, the second connecting rod 20 is directly rotationally connected to the air guide plate 70 through the second rotating shaft 502, and is slidingly connected to the air guide plate 70 through the cooperation of the sliding column and the sliding groove. During the movement of the air guide plate 70, the distance between the sliding column and the second rotating column changes, so the requirements for the relationship between the movement speed of the first rotating shaft 501 and the movement speed of the second rotating shaft 502 are not as strict as in this application.
[0144] like Figure 44As shown, with A0 as the coordinate point 0 and the direction of A0B0 as the X-axis, a coordinate system is established, and the formula is simplified. Let A0B0=L1, A0D0=L2, B0C0=L3, C0D0=L4, ∠XA0D0=A, ∠XB0C0=B, ∠C1C0D0=C (C1C0 is parallel to the X-axis). When the air guide plate is in the closed position, the first rotation axis is located at point C0, the second rotation axis is located at point D0, ∠XA0D0 is the angle between the positive direction of the X-axis and A0D0, ∠XB0C0 is the angle between the positive direction of the X-axis and B0C0, A1A2 is an arc with B0 as the center. When the first rotation axis moves from A1 to A2, the angular velocity of the first rotation axis rotating around B0 is ω B , B1B2 is an arc with the center at A0. When the second rotation axis moves from B1 to B2, the angular velocity of the second rotation axis around A0 is ω A , the angular velocity of C0D0 rotating around the axis C0 is ω C , the angular velocity of C is ω C ,ω C It can be understood as the angular velocity of the line connecting the first rotation axis and the second rotation axis rotating around the first rotation axis, that is, the rotation change rate of C. According to the principle of the linkage mechanism, it can be obtained:
[0145] L1+L3*cosB+L4*cosC=L2*cosA ①
[0146] L3*sinB-L4*sinC=L2*sinA②
[0147] The variables in the formula are A, B, and C. Differentiate formulas ① and ② with respect to time T, and we get
[0148] -L3*sinB*ω B -L4*sinC*ω C =-L2*sinA*ω A ③
[0149] L3*cosB*ω B -L4*cosC*ω C =L2*cosA*ω A ④
[0150] Combining equations ① to ④, we can get
[0151]
[0152] Let m = L3*sinB - L2*sinA, n = L2*cosA - L3*cosB - L1, simplify equation ⑤, and we can get the angular velocity ratio between the first and second rotation axes, which is:
[0153]
[0154] To simplify the design, a fixed transmission ratio (i.e., uniform speed transmission) is used for the second tooth section and first tooth segment driving the second rotating shaft. The radius of the pitch line of the first tooth section and first rack driving the first rotating shaft can be calculated using Equation 6. Based on the structural position design method, the location of the drive wheel center E and radius R1 of E1, as well as the radius L5 of D5 and D6, are determined. L5 differs from the rotation radius of the first rotating shaft.
[0155] Assume the angular velocity of the driving wheel is ω1, the radius of C5C6 is r1, the radius of C5C7 is r2, and the initial angle of B is θ1, that is, when the wind deflector is in the closed position, B = θ1. The center distance B0E = a, then
[0156]
[0157] Combining equations ⑦ and ⑧, we can get the transmission ratio i
[0158]
[0159] The equation of the nodal line C5C6 is:
[0160]
[0161] The equation of the nodal line C5C7 is:
[0162]
[0163] φ is the angle between the radius of the pitch line of the first rack and the polar axis. is an equation in polar coordinates.
[0164] Combine ⑤, ⑥, ⑨, ⑩, Formula, import mathematical calculation software, write a calculation program, draw the pitch line C5C6 and pitch line C5C7 graphics, import the pitch curve graphics into 3D drawing software, and then draw its tooth profile according to the tooth shape design method (for example, the method disclosed in application number CN202310777054.8).
[0165] The above transmission ratio is applicable to the stage when the second rotating shaft moves along B1B2.
[0166] like Figure 1 、 Figure 2 and Figure 7 As shown, the first box cover 61 is provided with a first limiting portion, and the second box cover 62 is provided with a second limiting portion; the second connecting rod 20 is provided with a first limiting matching portion that cooperates with the first limiting portion and a second limiting matching portion that cooperates with the second limiting portion to limit the movement of the second connecting rod 20 in the direction of the line connecting the first box cover 61 and the second box cover 62.
[0167] Optionally, the first limiting portion includes a limiting area formed by the first box cover 61 protruding toward the second connecting rod 20, which reduces the distance between the limiting area and the second connecting rod 20, thereby facilitating the contact and cooperation between the first limiting portion and the first limiting matching portion, and the limiting area can also enhance the strength of the first box cover 61. The first limiting matching portion includes a first limiting column provided on the second connecting rod 20, and the first limiting column abuts against the limiting area and can move relative to the limiting area.
[0168] During the opening of the air guide plate 70, the second connecting rod 20 moves, and the first limiting fitting part moves with the second connecting rod 20. Therefore, the size of the limiting area needs to meet the requirement that the limiting area can always be in contact with the first limiting fitting part throughout the full range of movement of the first limiting fitting part.
[0169] Optionally, one of the first limiting portion and the first limiting matching portion includes a first limiting groove, and the other includes a first limiting column, and the first limiting column is located in the first limiting groove and can move relative to the first limiting groove.
[0170] The third guide fitting part 621 and / or the fourth guide fitting part 625 can be used as the second limiting part, that is, the second limiting part includes the third guide fitting part 621 and / or the fourth guide fitting part 625, and accordingly, the second limiting part includes the third guide fitting part 621 and the fourth guide fitting part, which can simplify the structure of the second box cover 62 and the second connecting rod 20.
[0171] Alternatively, as Figure 7 As shown, the driving device for the air-conditioning air guide plate further includes a third limiting portion, which is supported between the first connecting rod 10 and the second connecting rod 20.
[0172] The third limiting portion is fixed to the first connecting rod 10 or the second connecting rod 20 and is made of wear-resistant material. The third limiting portion is supported between the first connecting rod 10 and the second connecting rod 20 to avoid direct contact between the first connecting rod 10 and the second connecting rod 20, thereby reducing wear of the first connecting rod 10 and the second connecting rod 20.
[0173] The driving wheel 30 also includes a first driving part 303; the first connecting rod 10 also includes a first driving matching part 104, and the first driving part 303 and the first driving matching part 104 slide or roll to drive the first connecting rod 10 to move; wherein, in the process of the driving wheel 30 driving the first connecting rod 10 to move, the engagement of the first rack 101 and the first tooth part 301, and the cooperation of the first driving part 303 and the first driving matching part 104 occur in sequence, or the cooperation of the first driving part 303 and the first driving matching part 104, and the engagement of the first rack 101 and the first tooth part 301 occur in sequence.
[0174] As the driving wheel 30 rotates, the first tooth portion 301 first engages with the first rack 101 to drive the first connecting rod 10 to move, and then the first driving portion 303 and the first driving engagement portion 104 slide or roll to drive the first connecting rod 10 to move. Alternatively, the first driving portion 303 and the first driving engagement portion 104 first slide or roll to drive the first connecting rod 10 to move, and then the first tooth portion 301 engages with the first rack 101 to drive the first connecting rod 10 to move. The movement of the first connecting rod 10 drives the movement of the air deflector 70, thereby opening and closing the air deflector 70.
[0175] The cooperation between the first tooth portion 301 and the first rack 101 is more reliable and stable than the cooperation between the column and the groove, and reduces the wear of the cooperation between the column and the groove; and the meshing of the first rack 101 and the first tooth portion 301, and the cooperation between the first drive portion 303 and the first drive matching portion 104 occur in sequence, or the cooperation between the first drive portion 303 and the first drive matching portion 104, and the meshing of the first rack 101 and the first tooth portion 301 occur in sequence, which can conveniently change the motion parameters of the first connecting rod 10, such as the motion trajectory or motion speed, thereby realizing a variety of wind-guiding positions of the wind guide plate 70.
[0176] Alternatively, as Figure 8 As shown in FIG9 , the driving wheel 30 includes a first surface 304 and a second surface 305 that are oppositely disposed. The first tooth portion 301 and the first driving portion 303 are both disposed on the first surface 304 , and are located at the same height in the axial direction of the driving wheel.
[0177] On the one hand, a second tooth portion 302 can be provided on the second surface 305 so that the first connecting rod 10 and the second connecting rod 20 do not interfere with each other. On the other hand, this arrangement improves the integration of the driving wheel 30, so that the driving wheel 30 can realize multiple functions on one plane.
[0178] Optionally, the first tooth portion 301 extends along the circumference of the driving wheel 30 and is non-annular.
[0179] Since the first tooth portion 301 is not a ring extending along the circumference of the driving wheel 30, that is, the first tooth portion 301 does not occupy a circle of the circumference of the driving wheel 30, the first tooth portion 301 and the first rack 101 may be disengaged during the process of the driving wheel 30 rotating one circle, thereby realizing the switching from the engagement of the first tooth portion 301 and the first rack 101 to the engagement of the first driving portion 303 with the first driving matching portion 104.
[0180] Optionally, one of the first driving portion 303 and the first driving matching portion 104 includes a first driving column 105 , and the other includes a first driving slot 312 adapted to the first driving column 105 .
[0181] When the first driving portion 303 cooperates with the first driving matching portion 104, the first driving column 105 is located in the first driving groove 312 and can slide or roll relative to the first driving groove 312, thereby realizing the driving of the first driving matching portion 104 by the first driving portion 303, that is, realizing the driving wheel 30 drives the first connecting rod 10 to move.
[0182] Optionally, the first driving slot 312 has an open end 315 , and the open end 315 passes through the edge of the driving wheel 30 or the first connecting rod 10 , and the first driving column 105 is inserted into or removed from the first driving slot 312 through the open end 315 of the first driving slot 312 .
[0183] When the first drive column 105 is not engaged with the first drive slot 312, the first drive column 105 is located outside the first drive slot 312. When the first drive column 105 is engaged with the first drive slot 312, the first drive column 105 is inserted into the first drive slot 312 through the open end 315 of the first drive slot 312. When the first drive column 105 is no longer engaged with the first drive slot 312, the first drive column 105 is disengaged from the first drive slot 312 through the open end 315 of the first drive slot 312.
[0184] like Figure 9a and Figure 9b As shown, the first driving slot 312 is provided on the driving wheel 30 , and the opening end 315 of the first driving slot 312 passes through the edge of the driving wheel 30 .
[0185] Optionally, when the first driving portion 303 includes the first driving slot 312 , the first driving slot 312 includes a first slot section 313 . The first slot section 313 is provided on the inner side of the first tooth portion 301 and extends along the circumferential direction of the driving wheel 30 .
[0186] The first groove section 313 is located on the inner side of the first tooth portion 301, meaning that the first groove section 313 is located between the first tooth portion 301 and the rotation center M of the drive wheel 30. Compared to the first groove section 313 extending radially along the drive wheel 30, the first groove section 313 in the present application extends circumferentially along the drive wheel 30. When the drive wheel 30 rotates through the same angle, the movement stroke of the first connecting rod 10 is reduced, thereby enabling the first connecting rod 10 to reciprocate in the second trajectory segment A2A3.
[0187] The first drive slot 312 also includes a second slot section 314. One end of the second slot section 314 forms an open end 315 of the first drive slot 312, and the other end of the second slot section 314 communicates with the first slot section 313. The second slot section 314 does not extend along the circumference of the drive wheel 30. Therefore, when the first drive post 105 engages with the second slot section 314, and the drive wheel 30 rotates through the same angle, the movement stroke of the first connecting rod 10 is greater than when the first drive post 105 engages with the first slot section 313.
[0188] Optionally, when the first driving column 105 cooperates with the second slot section 314 , the motion trajectory of the first rotating shaft 501 is located in the A1A2 section.
[0189] Optionally, the first rack 101 and the first driving engagement portion 104 are sequentially arranged along the length direction of the first connecting rod 10 .
[0190] In this way, when the first connecting rod 10 moves, the meshing of the first tooth portion 301 and the first rack 101 and the cooperation of the first driving portion 303 and the first driving matching portion 104 occur in sequence, or the cooperation of the first driving portion 303 and the first driving matching portion 104 and the meshing of the first tooth portion 301 and the first rack 101 occur in sequence.
[0191] Alternatively, as Figure 7 and Figure 8 As shown, the first connecting rod 10 further includes a connecting rod 109 , which is protruded from the side of the first rack 101 facing the driving wheel 30 , and the first driving engagement portion 104 is provided on the connecting rod 109 so that the first driving portion 303 can be engaged with the first driving engagement portion 104 .
[0192] Optionally, when the first driving portion 303 and the first driving mating portion 104 switch from the non-mating state to the mating state, the first tooth portion 301 and the first rack 101 are in a meshing state.
[0193] When the first tooth portion 301 is engaged with the first rack 101 to the end but has not yet separated, the first drive column 105 enters the first drive groove 312. At this time, the first connecting rod 10 is constrained by the first tooth portion 301 and the first drive portion 303 at the same time. At this time, the constraint on the first drive matching portion 104 is equivalent to the constraint on the first rack 101. When the first rack 101 is disengaged from the first tooth portion 301, the first drive matching portion 104 is constrained by the first drive portion 303, so that the first connecting rod 10 runs according to the designed trajectory.
[0194] Optionally, there are multiple first drive parts 303, and the number of first drive matching parts 104 is equal to and corresponds to the number of first drive parts 303; multiple first drive parts 303 are matched with the corresponding first drive matching parts 104 in turn, and when the first first drive part 303 and the first drive matching part 104 switch from a non-matching state to a matching state, the first tooth part 301 and the first rack 101 are in a meshing state.
[0195] The multiple first driving parts 303 are respectively a first first driving part 303, a second first driving part 303, etc. When the first tooth portion 301 is still in meshing state with the first rack 101, the first first driving part 303 and the first driving matching part 104 have switched from a non-matching state to a matching state. Thus, before the first tooth portion 301 is disengaged from the first rack 101, at least one first driving part 303 is matched with the first driving matching part 104. At this time, the meshing of the first tooth portion 301 and the first rack 101 and the matching of the first driving part 303 and the first driving matching part 104 jointly drive the movement of the first connecting rod 10, achieving a smooth switching from the meshing of the first tooth portion 301 and the first rack 101 to the matching of the first driving part 303 and the first driving matching part 104.
[0196] When the air guide plate 70 is opened, the driving wheel 30 rotates, the second tooth portion 302 engages with the second rack 201 , and after the driving wheel 30 rotates to the set position, the first driving portion 303 cooperates with the first driving matching portion 104 .
[0197] After the drive wheel 30 rotates to the set position, the first drive portion 303 engages with the first drive engagement portion 104 to drive the first connecting rod 10, and the second tooth portion 302 engages with the second rack 201 to drive the second connecting rod 20. Compared to the related art, the use of the second tooth portion 302 to engage with the second rack 201 in the second connecting rod 20 reduces the number of posts and slots, thereby reducing wear on the second connecting rod 20 and the drive wheel 30. Furthermore, the first connecting rod 10 is driven by the cooperation of the first drive portion 303 and the first drive engagement portion 104, while the second connecting rod 20 is driven by the cooperation of the second tooth portion 302 and the second rack 201. This combination of multiple drive methods facilitates the flexible movement of the air deflector 70.
[0198] Alternatively, as Figure 10 and Figure 11 As shown, the second rack 201 is a non-linear rack.
[0199] This arrangement enables the second connecting rod 20 to not be limited to linear motion, that is, the second connecting rod 20 can achieve a more complex motion trajectory during the movement process, meeting the diverse requirements of the air conditioner for the position and angle of the air guide plate 70 in different working modes.
[0200] Alternatively, as Figure 10 and Figure 11 As shown, the second rack 201 includes a first tooth segment 206 and a second tooth segment 207 arranged in sequence along the length direction of the second connecting rod 20, the pitch line D5D6 of the first tooth segment 206 is arc-shaped, and the pitch line D6D7 of the second tooth segment 207 is non-arc-shaped. When the second tooth portion 302 is engaged with the second tooth segment 207, the first driving portion 303 cooperates with the first driving matching portion 104.
[0201] The pitch line D6D7 of the second tooth segment 207 is non-circular and its center of curvature is not fixed. When the second tooth portion 302 is engaged with the second tooth segment 207, the second connecting rod 20 does not perform translational motion but deflection motion. The wind deflector 70 moves under the joint drive of the first connecting rod 10 and the second connecting rod 20, so the motion trajectory of the first connecting rod 10 needs to match the motion trajectory of the second connecting rod 20. When the second connecting rod 20 performs deflection motion, the first connecting rod 10 cannot simply perform linear motion. Therefore, at this time, the first connecting rod 10 is driven by a gear rack, and the shape of the rack on the first connecting rod 10 will be more complex. In other words, when the second tooth portion 302 is engaged with the second tooth segment 207, the first connecting rod 10 uses the first drive portion 303 to cooperate with the first drive matching portion 104, which can more easily meet the requirements for the motion trajectory of the first connecting rod 10.
[0202] When the first driving part 303 cooperates with the first driving matching part 104, the first rotating shaft 501 has reciprocating motion. This can be understood as, when the first driving part 303 cooperates with the first driving matching part 104, the entire stroke of the first rotating shaft 501 is reciprocating motion, or only part of the stroke is reciprocating motion. The second rotating shaft 502 has a non-circular trajectory motion. This can be understood as, when the first driving part 303 cooperates with the first driving matching part 104, the entire stroke of the second rotating shaft 502 is along the non-circular trajectory, or only part of the stroke is along the non-circular trajectory.
[0203] During the process of opening the air guide plate 70 from the first position to the extreme position, the driving wheel 30 rotates unidirectionally and the first rotating shaft 501 reciprocates. When the driving wheel 30 rotates unidirectionally, it is difficult to achieve reciprocating motion by using a gear rack drive. Therefore, when the first driving part 303 is provided to cooperate with the first driving matching part 104, the first rotating shaft 501 reciprocates.
[0204] When the first driving part 303 cooperates with the first driving cooperation part 104, the first rotating shaft 501 has reciprocating motion, the second rotating shaft 502 has a non-circular arc trajectory motion, and the first connecting rod 10 and the second connecting rod 20 cooperate to meet the requirements for the wind guide position of the wind guide plate 70.
[0205] Optionally, the first rack 101 and the first drive mating portion 104 are arranged in sequence along the length direction of the first connecting rod 10. When the first drive portion 303 and the first drive mating portion 104 are not engaged, the first tooth portion 301 is engaged with the first rack 101, thereby enabling the first connecting rod 10 to move through the engagement of the first tooth portion 301 with the first rack 101.
[0206] When the first tooth portion 301 is not engaged with the first rack 101 , the first driving portion 303 cooperates with the first driving engagement portion 104 , thereby driving the first connecting rod 10 to move.
[0207] Alternatively, as Figure 7 and Figure 8 As shown, the first rack 101 is a non-linear rack.
[0208] This enables the first connecting rod 10 to achieve a more complex motion trajectory during movement, rather than being limited to linear motion, thereby meeting the diverse requirements of the air conditioner for the position and angle of the air guide plate 70 under different working modes.
[0209] Optionally, the driving wheel 30 includes a first surface 304 and a second surface 305 that are oppositely arranged. The first tooth portion 301 and the first driving portion 303 are both arranged on the first surface 304 , and the second tooth portion 302 is arranged on the second surface 305 .
[0210] The first tooth portion 301 and the first driving portion 303 drive the first connecting rod 10, and the second tooth portion 302 drives the second connecting rod 20. The first tooth portion 301 and the first driving portion 303 are both arranged on the first surface 304, and the second tooth portion 302 is arranged on the second surface 305, so that the positions of the first tooth portion 301 and the first driving portion 303 and the position of the second tooth portion 302 do not interfere with each other, thereby making the movements of the first connecting rod 10 and the second connecting rod 20 do not interfere with each other.
[0211] The rotation axis of the driving wheel 30 is arranged perpendicular to the first surface 304 and the second surface 305 .
[0212] The first link 10 and the second link are provided in the mechanism box 6 and move relative to the mechanism box 6 between a retracted position for retracting the mechanism box 6 and an extended position for extending the mechanism box 6 .
[0213] The driving device for the air-conditioning air guide plate further includes a power source, which includes a driving wheel 30 .
[0214] like Figure 6As shown, the mechanism box 6 is provided with a stroke limiting area 636; the first connecting rod 10 includes a drive matching structure 115 that matches the first driving part 303, so that the power source drives the first connecting rod 10 to move, and the drive matching structure 115 is at least partially located in the stroke limiting area 636; wherein, during the movement of the first connecting rod 10, the drive matching structure 115 is at least partially located in the stroke limiting area 636 and moves relative to the stroke limiting area 636, so that the stroke limiting area 636 limits the movement area of the drive matching structure 115, so that the first connecting rod 10 moves between the first extreme position and the second extreme position, which can effectively prevent the first connecting rod 10 from being excessively offset during the movement, thereby accurately limiting the movement range and position of the air guide plate 70.
[0215] Optionally, the first connecting rod 10 is disposed between the power source and the first box cover 61, and the stroke limiting area 636 is disposed on the first box cover 61. On the one hand, the distance between the first connecting rod 10 and the stroke limiting area 636 is small, which facilitates the cooperation between the first connecting rod 10 and the stroke limiting area 636; on the other hand, the cooperation between the drive cooperation structure 115 and the stroke limiting area 636 does not affect the cooperation between the first driving part 303 and the power cooperation structure, that is, it does not affect the driving of the first connecting rod 10 by the power source.
[0216] Optionally, the surface of the mechanism box 6, such as the first box cover 61, is recessed toward the first connecting rod 10 to form a stroke limiting area 636. On the one hand, the recessed form ensures that the setting of the limiting area does not affect the setting of the drive matching structure 115. On the other hand, the strength of the first box cover 61 can also be enhanced.
[0217] Optionally, the first connecting rod 10 further includes a first rod body 114 including the first rack 101 ; the drive engagement structure 115 includes a first drive engagement portion 104 and a connecting rod 109 . The connecting rod 109 is connected between the first rod body 114 and the first drive engagement portion 104 .
[0218] During the movement of the first connecting rod 10 , the connecting rod 109 is located in the stroke limiting area 636 and moves relative to the stroke limiting area 636 , so that the stroke limiting area 636 defines the movement area of the drive engagement structure 115 .
[0219] The limiting effect of the stroke limiting area 636 on the drive matching structure 115 is achieved through the limiting effect of the stroke limiting area 636 on the connecting rod 109, rather than through the limiting effect of the stroke limiting area 636 on the first drive matching part 104, so that the limiting effect of the stroke limiting area 636 does not affect the matching between the first drive matching part 104 and the first drive part 303, and thus does not affect the drive of the first connecting rod 10 by the power source.
[0220] Optionally, the first box cover 61 , the connecting rod 109 and the first rod body 114 are arranged in sequence.
[0221] The first guide portion includes a second limiting column 125, which is provided on the connecting rod at a position corresponding to the first driving column. The second limiting column 125 and the first driving column are respectively located on opposite sides of the connecting rod. The second limiting column 125 is located in the stroke limiting area and moves relative to the stroke limiting area with the movement of the first connecting rod, and abuts against the side wall of the stroke limiting area to limit the position of the first connecting rod relative to the mechanism box.
[0222] The first surface 304 is provided with a first driving portion 303 for driving the first connecting rod 10 , and the second surface 305 is provided with a second tooth portion 302 for driving the second connecting rod 20 , wherein the first driving portion 303 includes a first driving slot 312 or a first driving column 105 .
[0223] The first drive portion 303 cooperates with the first connecting rod 10, and the second tooth portion 302 cooperates with the second connecting rod 20. The first drive portion 303 is provided on the first surface 304, and the second tooth portion 302 is provided on the second surface 305. In this way, the movements of the first connecting rod 10 and the second connecting rod 20 do not affect each other. In addition, the first drive portion 303 includes a first drive groove 312 or a first drive column 105, which is different from the second tooth portion 302 in the form of gear teeth. Through different forms, different movements of the first connecting rod 10 and the second connecting rod 20 can be achieved, thereby making it easier to achieve differential movement of the first connecting rod 10 and the second connecting rod 20. There is no need to switch the driving state of the drive wheel 30 on the first rack 101 and the second rack 201 (simultaneous drive or separate drive) as in the related art, thereby simplifying the structure and control logic.
[0224] Optionally, the second tooth portion 302 extends along the circumference of the driving wheel 30 and is annular or non-annular.
[0225] For example, when the second connecting rod 20 is driven by the second tooth portion 302 throughout its entire movement, the second tooth portion 302 is annular.
[0226] Optionally, one of the first tooth portion 301 and the second tooth portion 302 is a cylindrical gear, and the other is a non-circular gear, and the axes of the first tooth portion 301 and the second tooth portion 302 coincide with each other.
[0227] Optionally, the driving wheel 30 includes a driving body 306, and a first power unit is provided on one side of the driving body 306 (i.e., the side where the first surface 304 is located), and a second power unit is provided on the other side (i.e., the side where the second surface 305 is located); the first connecting rod 10 is provided on one side of the driving body 306 and is drive-connected to the first power unit, and the first connecting rod 10 is drive-connected to the wind guide plate 70; the second connecting rod 20 is provided on the other side of the driving body 306 and is drive-connected to the second power unit, and the second connecting rod 20 is drive-connected to the wind guide plate 70; wherein, the driving body 306 is used to separate the first connecting rod 10 and the second connecting rod 20.
[0228] like Figure 1 As shown, the driving body 306 is used to separate the first connecting rod 10 and the second connecting rod 20, which can prevent the first connecting rod 10 from hitting the second power unit and the second connecting rod 20 from hitting the first power unit, thereby ensuring the movement accuracy of the first power unit and the second power unit. In other words, the driving body 306 can limit the movement of the first connecting rod 10 toward the second power unit and can also limit the movement of the second connecting rod 20 toward the first power unit, that is, limit the movement of the first connecting rod 10 and the second connecting rod 20 in the direction of the line connecting the first connecting rod 10 and the second connecting rod 20 (along the thickness direction of the mechanism box 6).
[0229] Optionally, the driving body 306 includes a wheel body 310 and a partition plate 311. The first power unit and the second power unit are both provided on the wheel body 310; the partition plate 311 is provided on the wheel body 310. When the air deflector 70 is at least partially opened, the partition plate 311 is provided between the first connecting rod 10 and the second connecting rod 20 to separate the first connecting rod 10 from the second connecting rod 20.
[0230] The partition plate 311 is used to separate the first connecting rod 10 and the second connecting rod 20, which can prevent the first connecting rod 10 from hitting the second power unit and also prevent the second connecting rod 20 from hitting the first power unit, thereby ensuring the movement accuracy of the first and second power units.
[0231] Optionally, the partition plate 311 is provided at the outer edge of the wheel body 310 and extends radially outwardly of the wheel body 310 , so that the arrangement of the partition plate 311 does not affect the arrangement of the first power unit and the second power unit.
[0232] Optionally, a first avoidance groove 120 for accommodating the partition plate 311 is provided on the surface of the first connecting rod 10 facing the driving body 306, so that when the partition plate 311 is arranged between the first connecting rod 10 and the second connecting rod 20, the partition plate 311 is located in the first avoidance groove 120 to avoid interference between the partition plate 311 and the first connecting rod 10; and / or a second avoidance groove 212 for accommodating the partition plate 311 is provided on the surface of the second connecting rod 20 facing the driving body 306, so that when the partition plate 311 is arranged between the first connecting rod 10 and the second connecting rod 20, the partition plate 311 is located in the second avoidance groove 212 to avoid interference between the partition plate 311 and the second connecting rod 20.
[0233] Optionally, the first power unit includes a first tooth portion 301, the first connecting rod 10 includes a first rack 101 for engaging with the first tooth portion 301, and the partition plate 311 is arranged corresponding to the first tooth portion 301, so that when the first tooth portion 301 engages with the first rack 101, the partition plate 311 is arranged between the first connecting rod 10 and the second connecting rod 20.
[0234] During the engagement of the first tooth portion 301 with the first rack 101 , the partition plate 311 is provided between the first connecting rod 10 and the second connecting rod 20 , that is, the partition plate 311 is used to limit the first connecting rod 10 and the second connecting rod 20 along the thickness direction of the mechanism box 6 .
[0235] Optionally, the first power unit includes a first driving unit 303, and the first connecting rod 10 includes a driving engagement structure 115 that is driven and engaged with the first driving unit 303, and the driving engagement structure 115 includes a first driving engagement portion 104 and a connecting rod 109. The first driving unit 303 slides or rolls with the driving engagement structure 115; the driving body 306 also includes a partition wall that protrudes radially outward along the wheel body 310. When the first driving unit 303 engages with the driving engagement structure 115, the partition wall is located between the driving engagement structure 115 and the second connecting rod 20 to separate the driving engagement structure 115 and the second connecting rod 20, that is, to separate the first connecting rod 10 and the second connecting rod 20, thereby limiting the movement of the first connecting rod 10 and the second connecting rod 20 in the thickness direction of the mechanism box 6.
[0236] When the first driving portion 303 is engaged with the drive engagement structure 115, the engagement between the first driving portion 303 and the drive engagement structure 115 can limit the movement of the first connecting rod 10 toward the second connecting rod 20, thereby eliminating the need for a partition wall. Furthermore, the partition plate 311 is staggered with the drive engagement structure 115. That is, when the first driving portion 303 is engaged with the drive engagement structure 115, the partition plate 311 is not positioned between the first connecting rod 10 and the second connecting rod 20. In other words, the partition plate 311 does not serve to limit the position of the first connecting rod 10 and the second connecting rod 20 along the thickness direction of the mechanism box 6.
[0237] Optionally, the first power unit includes a first driving unit 303, and the first connecting rod 10 includes a driving cooperation structure 115 that is driven and cooperated with the first driving unit 303, and the first driving unit 303 slides or rolls with the driving cooperation structure 115; the driving cooperation structure 115 is provided with a third avoidance groove 121, and when the first driving unit 303 cooperates with the driving cooperation structure 115, the driving body 306 is at least partially located in the third avoidance groove 121, so as to avoid interference between the driving body 306 and the first connecting rod 10.
[0238] Optionally, the radius of the second tooth portion 302 is smaller than the radius of the driving body 306 , so that the partition plate 311 is located outside the second tooth portion 302 , wherein the direction away from the rotation center of the driving wheel 30 is outside.
[0239] The second connecting rod is provided with a positioning portion 216 , and the mechanism box is provided with a positioning matching portion 630 . The positioning portion 216 cooperates with the positioning matching portion 630 to provide radial constraints on the second connecting rod along the driving wheel.
[0240] By providing a positioning portion 216 on the second connecting rod and a positioning matching portion 630 on the mechanism box, the second connecting rod can be effectively constrained in the radial direction of the drive wheel during movement. This design effectively solves the problem of the rack easily dislodging when the wind deflector is in the extreme position in the prior art, ensuring that the second connecting rod remains stable during movement, avoiding radial deformation or dislodging caused by external forces, thereby improving the stability and reliability of the wind deflector movement.
[0241] Optionally, the second connecting rod includes a first end portion 214 and a second end portion 215 in the length direction, the first end portion 214 is movably connected to the wind deflector, and the positioning portion 216 is provided at the second end portion 215 .
[0242] The second end 215 is far away from the middle of the second connecting rod and is a free end, which is more prone to deformation, causing the second end 215 to be more likely to be disengaged. Therefore, the positioning portion 216 is provided at the second end 215 to prevent the second end 215 from being disengaged from the second tooth portion during movement.
[0243] Optionally, one of the positioning portion 216 and the positioning matching portion 630 includes a positioning post 217 , and the other includes a positioning slot 631 . The positioning post 217 is disposed in the positioning slot 631 and can slide relative to the positioning slot 631 .
[0244] The positioning post 217 is adapted to the positioning slot 631, and the positioning mating portion 630 is provided on the first or second box cover. By adding the positioning post 217 and the positioning slot 631, the restraining force between the second connecting rod and the mechanism box is increased, thereby enhancing the stability of the second connecting rod position and preventing the second connecting rod from disengaging from the second tooth portion during movement.
[0245] Alternatively, as Figures 32 to 34 As shown, when the air deflector is opened to the extreme position, the surface of the positioning portion 216 radially away from the middle of the driving wheel abuts against the positioning matching portion 630 to limit the radial outward movement of the second connecting rod along the driving wheel.
[0246] The driving wheel can limit the radial inward movement of the second connecting rod along the driving wheel. Therefore, the positioning portion 216 and the positioning matching portion 630 are provided to limit the radial outward movement of the second connecting rod along the driving wheel, wherein the direction close to the rotation center of the driving wheel is inward, and the direction away from the rotation center of the driving wheel is outward.
[0247] Optionally, the positioning portion 216 includes a first positioning protrusion 218, the positioning matching portion 630 includes a second positioning protrusion 635, and the inner wall surface of the first box cover protrudes inward to form the second positioning protrusion 635. When the air guide plate is opened to the extreme position, the first positioning protrusion 218 abuts against the surface of the driving wheel radially away from the middle part of the driving wheel and the second positioning protrusion 635 to limit the radial outward movement of the second connecting rod along the driving wheel.
[0248] Optionally, the first positioning protrusion 218 is provided on the surface of the second connecting rod facing away from the driving wheel.
[0249] In this way, the first positioning protrusion 218 is arranged between the first box cover and the second box cover, so that the first positioning protrusion 218 can not only prevent the second connecting rod from being disengaged at the extreme position, but also limit the movement of the first connecting rod in the direction of the connecting line between the first box cover and the second box cover.
[0250] Alternatively, as Figure 10 、 Figure 11 、 Figure 37 and Figure 38 As shown, the second connecting rod is provided with a third guide portion and a fourth guide portion, and the third guide portion and the fourth guide portion are arranged between the first end portion 214 and the second end portion 215 of the second connecting rod, thereby enhancing the movement guidance of the second connecting rod in the mechanism box, so that the second connecting rod can slide more smoothly along the preset track during the movement.
[0251] Since the third guide portion and the fourth guide portion are disposed between the first end portion 214 and the second end portion 215 of the second connecting rod, and the third guide portion and the fourth guide portion are farther away from the second end portion 215 , the second end portion 215 is more likely to be de-toothed.
[0252] Optionally, an avoidance groove 222 is provided on the surface of the second connecting rod facing away from the driving wheel, and the first positioning protrusion 218 is partially provided in the avoidance groove 222, thereby reducing the length of the first positioning protrusion 218 extending from the second connecting rod and reducing the volume occupied by the second connecting rod during movement.
[0253] Optionally, the second positioning protrusion 635 includes a protrusion body 220 and a positioning wheel 221, and the protrusion body 220 is connected to the second connecting rod; the positioning wheel 221 is sleeved on the surface of the protrusion body 220 and is made of a different material from the protrusion body 220. At the extreme position, the positioning wheel 221 abuts against the second positioning protrusion 635.
[0254] A bend 637 is provided on the surface of the second positioning protrusion 635 facing the first positioning protrusion 218 . In the extreme position, the first positioning protrusion 218 is located at the bend 637 to better limit the position of the first positioning protrusion 218 .
[0255] The protrusion body 220 is fixedly connected to the second connecting rod or is integrally formed. Using a positioning wheel 221 made of a different material than the positioning protrusion effectively improves the wear and impact resistance of the positioning structure. The positioning wheel 221 can be supported by a wear-resistant material. When the positioning wheel 221 abuts the first positioning protrusion 218, it can better withstand external forces, reducing the risk of wear and damage and extending the service life of the positioning structure.
[0256] like Figure 40 and Figure 41 As shown, during the opening process of the air guide plate, the motion trajectory of the first rotating shaft includes the first trajectory segment A1A2 and the second trajectory segment A2A3, the motion trajectory of the second rotating shaft includes the third trajectory segment B1B2 corresponding to the first trajectory segment A1A2 and the fourth trajectory segment B2B3 corresponding to the second trajectory segment A2A3, the second trajectory segment A2A3 deviates from the first trajectory segment A1A2 and is located on one side of the first trajectory segment A1A2, so that the first connecting rod is offset, and the fourth trajectory segment B2B3 deviates from the third trajectory segment B1B2 and is located on one side of the third trajectory segment B1B2, so that the second connecting rod is offset.
[0257] Offset refers to both translation and rotation, collectively known as offset or deflection.
[0258] The first connecting rod and the second connecting rod are offset, so that the first connecting rod and the second connecting rod can change the opening angle and extension displacement of the wind deflector to a large extent, thereby allowing the wind deflector to have a variety of wind deflecting positions.
[0259] Optionally, the second track segment A2A3 is located on the side of the first track segment A1A2 that faces the third track segment B1B2. When the air deflector is opened, the second track segment A2A3 tilts toward the third track segment B1B2. When the air deflector is opened, the second track segment A2A3 tilts toward the end point B2 of the third track segment B1B2.
[0260] This arrangement ensures that as the first rotating shaft moves along the second trajectory segment A2A3, it gradually approaches the third trajectory segment B1B2 and, ultimately, point B2. The closer it gets to point B2, the shorter the length of the line connecting B2B3 (the length of the straight line connecting B2B3) becomes. This shortens the distance between B2 and B3, and their dimensions, resulting in a smaller mechanism box. Furthermore, the coordinated motion of the first and second rotating shafts ensures that the air deflector is driven to its target position.
[0261] Optionally, when the air deflector is opened, the first rotating shaft reciprocates along the second trajectory segment A2A3, which can shorten the movement stroke of the first connecting rod and reduce the space occupied by the first connecting rod during movement.
[0262] The first track segment A1A2 can be a straight line or a curve. The second track segment A2A3 can be a straight line or a curve. The third track segment B1B2 can be a straight line or a curve. The fourth track segment B2B3 can be a straight line or a curve.
[0263] Optionally, when the air guide plate is opened to the extreme position, the first rotating shaft returns to point A2, which can shorten the movement stroke of the first connecting rod. Since the relative positions of the second rotating shaft and the second rotating shaft remain unchanged, the movement stroke of the second connecting rod can be shortened, thereby reducing the space occupied by the entire driving device for the air-conditioning air guide plate.
[0264] Optionally, when the air guide plate moves from the closed position to the maximum air supply position, the first rotating shaft moves along the first track segment A1A2; when the air guide plate moves from the maximum air supply position to the extreme position, the first rotating shaft moves along the second track segment A2A3.
[0265] In this solution, at the maximum air supply position, the air guide plate is located in the middle of the air outlet, that is, the air outlet direction is perpendicular to the plane enclosed by the length and width of the air guide plate.
[0266] Optionally, during the opening process of the air deflector, the motion trajectory of the first rotating shaft includes the first trajectory segment A1A2 and the second trajectory segment A2A3, the motion trajectory of the first guide portion includes the fifth trajectory segment C1C2 and the sixth trajectory segment C2C3, the motion trajectory of the second guide portion 123 includes the seventh trajectory segment D1D2 and the eighth trajectory segment D2D3, the first trajectory segment A1A2, the fifth trajectory segment C1C2 and the seventh trajectory segment D1D2 correspond to each other, the second trajectory segment A2A3, the sixth trajectory segment C2C3 and the eighth trajectory segment D2D3 correspond to each other wherein, the second track segment A2A3 is located on the first side of the first track segment A1A2 (approximately the lower side of A1A2), the sixth track segment C2C3 is located on the third side of the fifth track segment C1C2 (approximately the lower side of C1C2), and the eighth track segment D2D3 is located on the fifth side of the seventh track segment D1D2 (approximately the lower side of D1D2), and the first side, the third side, and the fifth side are the same side, so that when the first rotation axis moves from along the first track segment A1A2 to along the second track segment A2A3, the first connecting rod is offset toward the same side.
[0267] The second track segment A2A3 is located on the first side of the first track segment A1A2, the sixth track segment C2C3 is located on the third side of the fifth track segment C1C2, and the eighth track segment D2D3 is located on the fifth side of the seventh track segment D1D2. The first side, the third side and the fifth side are the same side, so that when the first rotating axis moves from along the first track segment A1A2 to along the second track segment A2A3, the first connecting rod as a whole is offset in the same direction, which is the direction of the first side, the third side and the fifth side, thereby enriching the movement trajectory of the air guide plate, so that the air guide plate can achieve more precise and flexible adjustment of the air supply direction during the opening process, and can effectively reduce the interference between the first connecting rod and other mechanical components.
[0268] C1C2 and D1D2 are arc-shaped.
[0269] Optionally, the second track segment A2A3, the sixth track segment C2C3 and the eighth track segment D2D3 do not overlap after translation, so that the motion trajectories at the first rotation axis, the first guide part and the second guide part 123 on the first connecting rod are different. In this way, in addition to translational motion, the first connecting rod also has rotational motion, that is, deflection will occur.
[0270] The second track segment A2A3, the sixth track segment C2C3 and the eighth track segment D2D3 may be straight lines or curves.
[0271] Optionally, the second guide portion 123 is located between the first guide portion and the first rotation axis, the inclination of the second track segment A2A3 is greater than the inclination of the eighth track segment D2D3, and the inclination of the eighth track segment D2D3 is greater than the inclination of the sixth track segment C2C3.
[0272] The first rotation axis, second guide portion 123, and first guide portion are arranged in this order, with the second track segment A2A3 having the highest inclination, the eighth track segment D2D3 having the second highest, and the sixth track segment C2C3 having the lowest. This effectively reduces the wobble and offset of the first connecting rod during movement, improving movement stability. Furthermore, the first rotation axis is at the smallest distance from the air deflector, while the second track segment A2A3 has the highest inclination. This allows for significant adjustment of the air deflector's position, providing a variety of air guide positions.
[0273] During the opening process of the air deflector, the second guide portion 123 reciprocates along the eighth trajectory segment D2D3, moving from D2 to D3. When the air deflector reaches its limit position, it returns to D2. The first guide portion reciprocates along the sixth trajectory segment C2C3, moving from C2 to C3. When the air deflector reaches its limit position, it returns to C2. Specifically, when the first rotation axis moves to B2, the first guide portion is located at C2 and the second guide portion 123 is located at D2. When the first rotation axis moves to B3, the first guide portion is located at C3 and the second guide portion 123 is located at D3. At the limit position, the first rotation axis returns to B2, the first guide portion is located at C2, and the second guide portion 123 is located at D2.
[0274] A1A2, C1C2, and D1D2 are all arcs and are located at the same center, but have different radii. Although the radii are different, the angular velocities are the same, so there is no deflection when the first rotation axis moves along A1A2.
[0275] Example 2:
[0276] The difference from the first embodiment is that Figures 12 to 39 、 Figures 42 to 45 As shown, during the opening process of the air guide plate, the first rotation axis moves unidirectionally along the second track segment A2A3.
[0277] In this solution, at the maximum air supply position, the air guide plate extends out of the lower edge of the air outlet and is not located in the middle of the air outlet, which can extend the length of the air duct and prevent the air guide plate from blocking the wind.
[0278] Alternatively, as Figure 43 As shown, the second track segment A2A3 is located on the first side of the first track segment A1A2, and the sixth track segment C2C3 is located on the fourth side of the fifth track segment C1C2, and the first side and the fourth side are opposite sides. (Wherein, as shown Figure 43 In the figure, the first side and the fourth side are the upper sides.
[0279] The first side and the fourth side are opposite sides, so that when the first rotating axis moves along the second trajectory segment A2A3, the first connecting rod has not only translational motion but also rotational motion, forming a deflection motion, thereby reducing the opening of the first connecting rod at the cover shell, similar to the principle of changing the motion trajectory of the second connecting rod to reduce the opening corresponding to the second connecting rod on the cover shell.
[0280] Optionally, the eighth track segment D2D3 is located on the fifth side of the seventh track segment D1D2, the first side and the fifth side are the same side, and the fifth side is the lower side.
[0281] When the first rotating shaft moves along the second track segment A2A3, it is equivalent to the first connecting rod rotating around the second guide portion 123, forming a deflection movement of the first connecting rod, thereby reducing the opening on the cover corresponding to the first connecting rod.
[0282] Alternatively, the first side and the fifth side may be opposite sides, that is, the fifth side and the fourth side may be the same side.
[0283] The inclination of the second track segment A2A3 is greater than the inclination of the eighth track segment D2D3; and / or the inclination of the sixth track segment C2C3 is greater than the inclination of the eighth track segment D2D3.
[0284] This arrangement enables the first rotating shaft to move along the second track segment A2A3, which is equivalent to the first connecting rod rotating around the second guide portion 123, thereby reducing the opening of the cover shell.
[0285] During the opening process of the air guide plate, the second tooth portion and the second rack are first externally meshed and then internally meshed; the pitch line of the second rack includes a second pitch line segment D6D7, the second pitch line segment D6D7 corresponds to the internal meshing, and the curvature radius of the second pitch line segment D6D7 changes continuously.
[0286] When the second tooth portion is engaged with the second rack, the pitch line of the second rack includes a second pitch segment D6D7, and the curvature radius of the second pitch segment D6D7 changes continuously, so that the second pitch segment D6D7 is neither an arc nor a straight line, and the curvature radius changes continuously, so that the second pitch segment D6D7 is smooth and gradual, and is not a combination of multiple arcs and straight lines in the comparative document 1. It can be seen that the movement of the second connecting rod is smoother, and the third guide groove and the fourth guide groove are also smoother. It is not the form of multiple guide segments in the related art, and does not include multiple straight line transition segments in the related art, so that the length of the second connecting rod can also be reduced.
[0287] Alternatively, as Figure 45As shown, the pitch line of the second rack also includes: a first pitch line segment D5D6, the first pitch line segment D5D6 corresponds to the external meshing and is connected to the second pitch line segment D6D7; the first pitch line segment D5D6 is arc-shaped and has the same center as the third track segment B1B2, and D5D6 and B1B2 can have the same radius or different radius.
[0288] When the second tooth portion is externally meshed with the second rack, the pitch line of the second rack is the first pitch line segment D5D6. D5D6 and the third track segment B1B2 are both arc-shaped and have the same center, thereby meeting the motion track requirements of the second connecting rod.
[0289] Optionally, the tangent at the connection between the first section line segment D5D6 and the second section line segment D6D7 coincides with the tangent at the connection between the second section line segment D6D7 and the first section line segment D5D6, so that the first section line segment D5D6 and the second section line segment D6D7 are smoothly connected to improve the smoothness of the movement of the second rack.
[0290] The pitch line of the second rack further includes a third segment F3F4, which is located at one end of the second segment D6D7 away from the first segment D5D6; the curvature radius of the third segment F3F4 is constant, for example, an arc shape.
[0291] Optionally, when the air guide plate moves from the closed position to the maximum air supply position, the second tooth portion engages externally with the second rack; when the air guide plate moves from the maximum air supply position to the extreme position, the second tooth portion engages internally with the second rack.
[0292] like Figure 42 As shown, if the second tooth portion and the second rack are always in internal meshing during the movement of the air deflector from the closed position to the extreme position, the movement trajectory of the second rack is biased downward, as shown in FIG. Figure 42 As shown in Figure F111, the housing opening is located near the lower edge of the air outlet, which makes the indoor unit look unsightly. Furthermore, the upper end of the second rack is too close to the front panel, making the overall unit space structure difficult to design. If the air guide moves from the closed position to the extreme position, the second tooth portion and the second rack are always in external meshing. The lower end of the second rack's trajectory is tilted upward compared to when the air guide moves from the closed position to the extreme position. Figure 42 As shown in F131, it is further away from the bottom edge of the air outlet and thicker at the top, increasing the distance from the front panel. When the air deflector is opened, the second rotation axis moves from point F00 to point F01. F11 shows the trajectory of the second rotation axis in the case of internal meshing, F12 shows the linear connection between F00 and F01, and F13 shows the trajectory of the second rotation axis in the case of external meshing.
[0293] Therefore, the second tooth portion first meshes externally with the second rack and then meshes internally, which can prevent the upper end of the second rack from being too close to the front panel and the lower end from being too close to the lower edge of the air outlet. The front panel is the front wall of the indoor unit, located above the air outlet, and covering the front side of the housing.
[0294] An embodiment of the second aspect of the present invention provides an air conditioner, including an indoor unit 80, the indoor unit 80 including a shell, an indoor heat exchanger, a fan, an air guide plate 70 and a driving device for the air guide plate of the air conditioner as described in any of the above embodiments, the first connecting rod 10 is directly rotationally connected to the air guide plate 70 through a first rotating shaft 501, and the second connecting rod 20 is directly rotationally connected to the air guide plate 70 through a second rotating shaft 502.
[0295] The housing defines an air duct, which includes an air inlet and an air outlet 404. The indoor heat exchanger and fan are both located within the duct. Driven by the fan, air enters the duct through the air inlet, exchanges heat with the indoor heat exchanger, and then flows out of the air outlet 404. An air deflector 70 is located at the air outlet 404 to adjust the opening and closing of the air outlet 404 and the direction of air flow.
[0296] The air conditioner provided in the embodiment of the second aspect of the present invention includes a driving device for an air conditioner air guide plate as described in any one of the above embodiments, and thus has all the beneficial effects of the driving device for an air conditioner air guide plate as described in any one of the above embodiments, which will not be repeated here.
[0297] like Figure 29 As shown, the housing includes a front panel 403, and the indoor unit 80 also includes a cover 405. The cover 405 is located inside the front panel 403. The front panel 403 is provided with an air outlet 404, and the cover 405 is provided with an opening 406. The mechanism box 6, the opening 406, and the air deflector 70 are arranged in this order. When the air deflector 70 is opened, the first connecting rod 10 and the second connecting rod 20 extend through the opening 406.
[0298] The air guide plate 70 includes a plate body 701 for opening or closing the air outlet 404. The connecting portion 702 is protruded from a side of the plate body 701 facing the housing 405. When the air guide plate 70 is in the first position, the connecting portion 702 is located in the opening 406.
[0299] The first connecting rod 10 is directly rotatably connected to the connecting part 702 through the first rotating shaft 501. For example, the first connecting rod 10 is provided with a first axial hole 122, the connecting part 702 is provided with a second axial hole, and the first rotating shaft 501 is rotatably provided in the first axial hole 122 and the second axial hole, or, the first connecting rod 10 is provided with a first axial hole 122, the first rotating shaft 501 is provided in the connecting part 702, the first rotating shaft 501 passes through the first axial hole 122 and is rotatably connected to the first axial hole 122.
[0300] The second connecting rod 20 is directly rotatably connected to the connecting portion 702 via the second rotating shaft 502. For example, the second connecting rod 20 is provided with a third shaft hole 213, the connecting portion 702 is provided with a fourth shaft hole, and the second rotating shaft 502 is rotatably disposed in the third shaft hole 213 and the fourth shaft hole. Alternatively, the second connecting rod 20 is provided with a third shaft hole 213, the second rotating shaft 502 is provided in the connecting portion 702, and the second rotating shaft 502 passes through the third shaft hole 213 and is rotatably connected to the third shaft hole 213.
[0301] like Figure 39 As shown, in the process of the air guide plate 70 opening from the first position to the second position, when the first rotating shaft 501 passes through the opening 406, the width direction of the connecting portion 702 (such as Figure 22 The second rotation axis 502 does not exceed the edge of the connecting portion 702 in the width direction when in the first position (in the direction from the first edge 703 to the second edge 704), and / or, when the second rotation axis 502 passes through the opening 406, the second rotation axis 502 does not exceed the edge of the connecting portion 702 in the width direction when in the first position.
[0302] During the process of opening the air guide plate 70 from the first position to the second position, when the first rotating shaft 501 passes through the opening 406, the first rotating shaft 501 in the first position does not exceed the edge of the connecting portion 702 in the width direction of the connecting portion 702 in the first position, or the orthographic projection of the first rotating shaft 501 on the connecting portion 702 in the first position does not exceed the edge of the connecting portion 702 in the width direction of the connecting portion 702 in the first position, so as to limit the movement range of the first rotating shaft 501 when passing through the opening 406, thereby limiting the movement range of the entire first connecting rod 10, thereby reducing the cover 4 05, and / or, when the second rotating shaft 502 passes through the opening 406, the second rotating shaft 502 does not exceed the edge of the connecting portion 702 in the width direction when the second rotating shaft 502 is in the first position, or the positive projection of the second rotating shaft 502 on the connecting portion 702 when the second rotating shaft 502 is in the first position does not exceed the edge of the connecting portion 702 in the width direction when the second rotating shaft 502 is in the first position, so as to limit the movement range of the second rotating shaft 502 when passing through the opening 406, thereby limiting the movement range of the entire second connecting rod 20, thereby reducing the opening 406 of the cover 405.
[0303] The edges of the connecting portion 702 in the width direction include a first edge 703 and a second edge 704 that are relatively arranged. When the first rotating shaft 501 passes through the opening 406, the first rotating shaft 501 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position. In this way, when the first connecting rod 10 passes through the opening 406, the first connecting rod 10 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position, thereby limiting the size of the opening 406 and preventing the opening 406 from being too large. When the second rotating shaft 502 passes through the opening 406, the second rotating shaft 502 does not exceed the edge of the connecting portion 702 in the width direction when it is in the second position. In this way, when the second connecting rod 20 passes through the opening 406, the second connecting rod 20 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position, thereby limiting the size of the opening 406 and preventing the opening 406 from being too large.
[0304] The second connecting rod 20 includes a third guide column 203 and a fourth guide column 205. The mechanism box 6 is provided with a third guide groove 622 and a fourth guide groove 626. The third guide column 203 is provided in the third guide groove 622 and can move relative to the third guide groove 622. The fourth guide column 205 is provided in the fourth guide groove 626 and can move relative to the fourth guide groove 626 to guide the movement trajectory of the second connecting rod 20.
[0305] The third guide column 203 is arranged between the fourth guide column 205 and the second rotating shaft 502. In the process of opening the air guide plate 70 from the second position to the extreme position, the fourth guide column 205 and the second rotating shaft 502 have reverse movement, and under the constraint of the third guide groove 622, the third guide column 203 moves along the length direction of the third guide groove 622. This can be understood as the second connecting rod 20 rotating around the third guide column 203. The second connecting rod 20 can be imagined as a lever, and the third guide column 203 serves as the fulcrum of the lever. At the same time, the third guide column 203 moves in the third guide groove 622. The third guide column 203 does not move relative to the second connecting rod 20, and the second connecting rod 20 is driven to rotate around the third guide column 203 through the fourth guide column 205.
[0306] Optionally, when the air guide plate 70 is opened from the second position to the extreme position, the third guide column 203 does not exceed the edge of the connecting portion 702 in the width direction when the connecting portion 702 is in the first position.
[0307] The third guide column 203 serves as the rotation center of the second connecting rod 20, and while satisfying the motion trajectory of the second rotating axis 502 being B2B3, the second connecting rod 20 entity is always located between the first edge 703 and the second edge 704 in the width direction of the connecting part 702 when the opening 406 is in the first position, thereby reducing the size of the opening 406.
[0308] Optionally, during the process of the air guide plate 70 opening from the second position to the extreme position, when the first rotating shaft 501 passes through the opening 406, the first rotating shaft 501 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position. In this way, when the first connecting rod 10 passes through the opening 406, the first connecting rod 10 does not exceed the edge of the connecting portion 702 in the width direction when it is in the first position, thereby limiting the size of the opening 406 and preventing the opening 406 from being too large.
[0309] The indoor unit further includes a small guide plate 705, which and the air guide plate are sequentially arranged along the width direction of the air outlet to jointly close the air outlet and adjust the air outlet direction of the air outlet.
