[0041] Currently, the movement mechanism for the air deflector 70 has a relatively complex structure and is prone to failures during the movement of the air deflector 70. The embodiments of the present application provide a movement mechanism for the air deflector 70, which can be applicable to various types of air conditioners, such as household air conditioners or commercial air conditioners. The embodiments of the present application do not specifically limit the types of air conditioners adapted to this movement mechanism.

[0042] The embodiments of the present disclosure provide a movement mechanism for an air deflector, as Figures 1 to 7 shown.

[0043] In some embodiments, the motion mechanism for the air deflector 70 includes: a housing, a crank 10, and a connecting rod assembly. The housing is provided with an avoidance opening; the crank 10 is disposed inside the housing and is used for driving connection with the driving element 60; the connecting rod assembly is slidably connected to the crank 10, a part of the connecting rod assembly is disposed inside the housing, and the end of the connecting rod assembly extends out from the avoidance opening and is rotatably connected to the air deflector 70; wherein, the housing is used to define the motion trajectories of the crank 10 and the connecting rod assembly, so that the air deflector 70 first translates out of the air conditioner and then rotates.

[0044] In the embodiments of the present application, the motion mechanism for the air deflector 70 includes a housing, a crank 10, and a connecting rod assembly. Wherein, one end of the housing is provided with an avoidance opening, the crank 10 is disposed inside the housing and is drivingly connected to the driving element 60, a part of the connecting rod assembly is disposed inside the housing, the connecting rod assembly is slidably connected to the crank 10, and the end of the connecting rod assembly extends out of the housing and is rotatably connected to the air deflector 70. The crank 10 can rotate along a first direction or a second direction under the drive of the driving element 60. When the crank 10 rotates along the first direction from the initial position, the crank 10 pushes the connecting rod assembly to make the air deflector 70 first translate out of the air conditioner and then open upward. At this time, the crank 10 rotates along the second direction, and the crank 10 pulls the connecting rod assembly to make the air deflector 70 return to the closed state. When the crank 10 rotates along the second direction from the initial position, the crank 10 pushes the connecting rod assembly to make the air deflector 70 first translate out of the air conditioner and then open downward. At this time, the crank 10 rotates along the first direction, and the crank 10 pulls the connecting rod assembly to make the air deflector 70 return to the closed state. In this way, by driving the above-mentioned motion mechanism for the air deflector 70 with one driving element 60, the air deflector 70 can be opened upward, opened downward, or closed. During the above process, the initial position of the crank is as Figure 6 shown.

[0045] Optionally, the driving element 60 can be a bidirectional driving stepper motor. The stepper motor is provided with a driving shaft, and the crank 10 is drivingly connected to the stepper motor through the driving shaft.

[0046] Optionally, the connecting rod assembly includes a first connecting rod 20 and a second connecting rod 30. The top end of the first connecting rod 20 is slidably connected to the crank 10, the end of the first connecting rod 20 is rotatably connected to the air deflector 70, the second connecting rod 30 abuts against the first connecting rod 20, and one end of the second connecting rod 30 is rotatably connected to the air deflector 70.

[0047] Optionally, the top end of the first connecting rod 20 is slidably connected to the crank 10, and a first rotating shaft 23 is provided at the end of the first connecting rod 20. The first rotating shaft 23 is rotatably connected to the air deflector 70. In this way, the crank 10 rotates under the drive of the driving element 60, and then can push the first connecting rod 20 to make the air deflector 70 move. As Figure 3As shown, one side of the second link 30 abuts against the first link 20, and a second rotating shaft 32 is provided at the end of one side of the second link 30. The second rotating shaft 32 is rotatably connected to the air deflector 70. In this way, under the action of the crank 10, the first link 20 can move relative to the second link 30, thereby opening the air deflector 70 upward or downward.

[0048] Optionally, the housing includes a crank cover plate 40 and a link bottom plate 50. The link bottom plate 50 is fixedly connected to the crank cover plate 40, and the link bottom plate 50 is used to define the movement trajectories of the first link 20 and the second link 30.

[0049] Optionally, the crank cover plate 40 and the link bottom plate 50 are fixed by mutually matching screw nuts or plug-in components, such as Figure 1 As shown, the link bottom plate 50 is fixed to the housing of the air conditioner. In this way, during the movement of the air deflector 70, the housing is fixed to the air conditioner and will not move. The link bottom plate 50 is provided with a track portion 51 that defines the movement trajectories of the first link 20 and the second link 30. Under the push of the rotation of the crank 10, the first link 20 and the second link 30 move synchronously or relatively under the limitation of the track portion 51, thereby moving the air deflector 70.

[0050] Optionally, the link bottom plate 50 is provided with a first track groove 511, a second track groove 512, and a third track groove 513 that are parallel to each other, and the extending directions of the first track groove 511, the second track groove 512, and the third track groove 513 are the same as the direction in which the air deflector 70 translates out of the air conditioner.

[0051] Such as Figure 5 As shown, the surface of the link bottom plate 50 opposite to the crank cover plate 40 is provided with three tracks, namely, a first track groove 511, a second track groove 512, and a third track groove 513. The three tracks are arranged parallel to each other, and moreover, the extending directions of the first track groove 511, the second track groove 512, and the third track groove 513 are the same as the direction in which the air deflector 70 translates out of the air conditioner. That is, under the push of the crank 10, the first link 20 and the second link 30 can move synchronously along the above three tracks, so that the air deflector 70 translates out of the air conditioner. Among them, the three track grooves of the link bottom plate 50 are simultaneously used to define the movement trajectory of the first link 20, and the first track groove 511 of the link bottom plate 50 is used to define the movement trajectory of the second link 30.

[0052] Optionally, a first slider 211 that matches the first track groove 511, a second slider 212 that matches the second track groove 512, and a third slider 213 that matches the third track groove 513 are provided on the first side surface at the top of the first link 20.

[0053] Such as Figure 2 And Figure 3As shown, the first link 20 is in a "T" shape, having opposite first and second sides. A sunk groove 24 is provided on the first side. At the top inside the sunk groove 24, a first sliding part 21 is provided that matches the track part 51 of the link base plate 50. The first sliding part 21 includes a first slider 211 that matches the first track groove 511, a second slider 212 that matches the second track groove 512, and a third slider 213 that matches the third track groove 513. The first slider 211, the second slider 212, and the third slider 213 are arranged side by side horizontally. When the air deflector 70 is closed, the first slider 211 is located at the starting end of the first track groove 511, the second slider 212 is located at the starting end of the second track groove 512, and the third slider 213 is located at the starting end of the third track groove 513, as Figure 5 shown. In the embodiment of the present application, the starting end of the track part 51 is the end of the link base plate 50 away from the air deflector 70, and the end of the track part 51 is the end of the link base plate 50 close to the air deflector 70.

[0054] Optionally, on the side of the second link 30 adjacent to the link base plate 50, a fourth slider 311 and a fifth slider 312 are provided. The fourth slider 311 and the fifth slider 312 are used to move within the first track groove 511, and the fifth slider 312 is arranged close to the end of the first track groove 511.

[0055] Optionally, the second link 30 is arranged inside the sunk groove 24 of the first link 20, and one side of the second link 30 abuts against the first link 20. On the other side of the second link 30, that is, on the side of the second link 30 adjacent to the link base plate 50, a second sliding part 31 is provided. The second sliding part 31 matches the first track groove 511 of the link base plate 50. Optionally, the second sliding part 31 includes a fourth slider 311 and a fifth slider 312. Both the fourth slider 311 and the fifth slider 312 are used to move within the first track groove 511. The arrangement positions of the fourth slider 311 and the fifth slider 312 on the second link 30 match the extending direction of the first track. When the air deflector 70 is closed, the fourth slider 311 is arranged at a position close to the starting end of the first track groove 511, and the fifth slider 312 is arranged at a position close to the end of the first track groove 511.

[0056] Optionally, the length of the first track groove 511 is greater than the lengths of the second track groove 512 and the third track groove 513 respectively. Among them, when the fifth slider 312 moves to the end of the first track groove 511, the air deflector 70 translates and extends out of the air conditioner to the maximum preset distance.

[0057] In the embodiment of the present application, the crank 10 rotates along the first direction or the second direction under the drive of the drive element 60. During the rotation of the crank 10, the first link 20 is pushed to move along the track portion 51 of the link base plate 50. The air deflector 70 is translated and extended out of the air conditioner under the push of the first link 20. By connecting with the second rotating shaft 32, the air deflector 70 pulls the second link 30 to move along the first track groove 511 of the link base plate 50. When the fifth slider 312 of the second link 30 moves to the end of the first track groove 511, the second link 30 stops moving, and the air deflector 70 is translated and extended out of the air conditioner to the maximum preset distance. During the process that the fifth slider 312 of the second link 30 moves to the end of the first track groove 511, the first link 20 and the second link 30 move synchronously. During the translation of the air deflector 70 as described above, the length of the first track groove 511 needs to be greater than the lengths of the second track groove 512 and the third track groove 513 respectively, so that the first link 20 and the second link 30 can move synchronously. The maximum preset distance is the maximum distance that the air deflector 70 can be translated and extended out of the air conditioner. At this maximum preset distance, the air deflector 70 can be rotated upward or downward to the maximum opening angle, such as Figure 7 and Figure 8 shown. The maximum preset distance is related to factors such as the length of the track portion 51 of the link base plate 50, the lengths of the first link 20 and the second link 30, etc.

[0058] Optionally, the crank 10 has a free end and a rotating end. A sliding column 11 is provided at the free end, and the sliding column 11 is used for slidably connecting with the first link 20.

[0059] Optionally, the rotating end of the crank 10 is drivingly connected to the drive element 60. The drive element 60 can drive the crank 10 to rotate bidirectionally. A sliding column 11 is provided on the side surface of the free end of the crank 10 that contacts the first link 20, and the sliding column 11 is used for slidably connecting with the first link 20, such as Figure 2 shown.

[0060] Optionally, a crank cover plate 40 is disposed between the crank 10 and the drive element 60. The crank cover plate 40 is used to define the rotation trajectory of the crank 10, so that the circular motion trajectory of the crank 10 is more accurate. Optionally, a first groove 41 matching the crank 10 is provided on the side of the crank cover plate 40 opposite to the connecting rod bottom plate 50. During the rotation of the crank 10, the free end of the crank 10 remains in contact with the arc-shaped edge of the first groove 41. Among them, the above-mentioned contact state does not cause a large frictional force between the free end of the crank 10 and the arc-shaped edge of the first groove 41, resulting in the inability of the crank 10 to rotate. Instead, during the rotation of the crank 10, the free end of the crank 10 just contacts the arc-shaped edge of the first groove 41, and the arc-shaped edge of the first groove 41 can ensure the circular motion trajectory of the crank 10 and prevent the rotation trajectory of the crank 10 from shifting under the drive of other acting forces. It can be understood that the shape of the first groove 41 is a circular groove with the rotation center of the crank 10 as the center of the circle.

[0061] Optionally, a connection hole 411 is provided at the center position of the first groove 41. The connection hole 411 is used to fix the crank 10 and the drive element 60. Optionally, a boss 12 matching the connection hole 411 is provided at the rotating end of the crank 10. The boss 12 is snap-fitted with the connection hole 411. In this way, the crank 10 can be installed and fixed on the inner side surface of the crank cover plate 40. Optionally, the drive element 60 is disposed on the outer side surface of the crank cover plate 40, and the drive shaft of the drive element 60 is drivingly connected to the crank 10 through the above-mentioned connection hole 411.

[0062] Optionally, a chute 22 matching the sliding column 11 is provided on the second side surface of the first connecting rod 20. The chute 22 is linear, and the length of the chute 22 can meet the rotation requirements of the crank 10. Optionally, the length of the chute 22 is greater than or equal to the diameter of a circle with the rotation center of the crank 10 as the center of the circle and the distance from the rotation center to the sliding column 11 as the radius.

[0063] As Figure 2 and Figure 3 shown, a sinking groove 24 is provided on the first side surface of the first connecting rod 20, and a first sliding part 21 is provided in the sinking groove 24. The first sliding part 21 includes a first slider 211, a second slider 212 and a third slider 213 arranged side by side horizontally. A chute 22 is provided on the second side surface of the first connecting rod 20, and the chute 22 matches the sliding column 11 at the free end of the crank 10. The sliding column 11 of the crank 10 can slide in the chute 22 during the rotation process.

[0064] In the embodiment of the present application, the crank 10 can not only rotate under the drive of the drive element 60, but also the sliding column 11 at the free end of the crank 10 can slide along the chute 22 of the first connecting rod 20. In this way, through the sliding between the crank 10 and the first connecting rod 20, the first connecting rod 20 can be driven to move along the track portion 51 of the connecting rod bottom plate 50, so as to move the air deflector 70. The movement track of the air deflector 70 is divided into two steps. First, the air deflector 70 first translates out of the air conditioner to the maximum preset distance, and then the air deflector 70 rotates. It is defined that Figure 6 the first direction of rotation of the crank 10 is the clockwise direction, and the second direction of rotation of the crank 10 is the counterclockwise direction.

[0065] In the embodiment of the present application, the driving process of the upward opening of the air deflector 70 is as follows:

[0066] The initial position of the crank 10 is as Figure 6 shown. The crank 10 rotates in the clockwise direction under the drive of the drive element 60. During the rotation of the crank 10, the sliding column 11 slides in the chute 22 of the first connecting rod 20, so as to push the first connecting rod 20 to move along the track portion 51 of the connecting rod bottom plate 50. The air deflector 70 is pushed by the first connecting rod 20 to translate out of the air conditioner. The air deflector 70 pulls the second connecting rod 30 to move along the first track groove 511 of the connecting rod bottom plate 50 through the connection with the second rotating shaft 32. When the fifth slider 312 of the second connecting rod 30 moves to the end of the first track groove 511, the second connecting rod 30 stops moving, and the air deflector 70 translates out of the air conditioner to the maximum preset distance. After the fifth slider 312 moves to the end of the first track groove 511, the crank 10 continues to rotate in the clockwise direction. The first connecting rod 20 continues to move along the track portion 51 of the connecting rod bottom plate 50 under the push of the crank 10. When the first slider 211 of the first connecting rod 20 abuts against the fourth slider 311 of the second connecting rod 30, the crank 10 continues to rotate clockwise, so that the end of the first connecting rod 20 slidably connected to the crank 10 swings downward along the rotation center until the third slider 213 slides to the end of the third track groove 513, and the air deflector 70 is opened upward to the maximum angle. In the above process, the rotation center of the first connecting rod 20 is the first slider 211. During the process that the air deflector 70 translates out of the air conditioner to the maximum preset distance, that is, during the process that the fifth slider 312 of the second connecting rod 30 moves to the end of the first track groove 511, the first connecting rod 20 and the second connecting rod 30 move synchronously. After the air deflector 70 translates out of the air conditioner to the maximum preset distance, the first connecting rod 20 and the second connecting rod 30 move relatively. After the air deflector 70 is opened upward to the maximum angle, the crank 10 rotates counterclockwise, pulling the first connecting rod 20 to make the air deflector 70 first rotate back to the maximum preset distance and then translate back to the closed state.

[0067] It can be understood that the driving process of the downward opening of the air deflector 70 is as follows:

[0068] The initial position of the crank 10 is as Figure 6 shown. Driven by the driving element 60, the crank 10 rotates counterclockwise. During the rotation of the crank 10, the sliding column 11 slides within the chute 22 of the first connecting rod 20, thereby pushing the first connecting rod 20 to move along the track portion 51 of the connecting rod base plate 50. The air deflector 70 is translated and extended out of the air conditioner under the push of the first connecting rod 20. The air deflector 70 pulls the second connecting rod 30 to move along the first track groove 511 of the connecting rod base plate 50 through the connection with the second rotating shaft 32. When the fifth slider 312 of the second connecting rod 30 moves to the end of the first track groove 511, the second connecting rod 30 stops moving, and the air deflector 70 is translated and extended out of the air conditioner to the maximum preset distance. After the fifth slider 312 moves to the end of the first track groove 511, the crank 10 continues to rotate counterclockwise, causing the end of the first connecting rod 20 slidably connected to the crank 10 to swing downward along the rotation center until the second slider 212 slides to the end of the second track groove 512, and the air deflector 70 is opened downward to the maximum angle. Wherein, the rotation center of the first connecting rod 20 is the first slider 211. After the air deflector 70 is opened downward to the maximum angle, the crank 10 rotates clockwise, pulling the first connecting rod 20 to first rotate the air deflector 70 back to the maximum preset distance and then translate it back to the closed state.

[0069] Optionally, a wide-mouth section 241 is provided at one end of the sunk groove 24 of the first connecting rod 20 close to the air deflector 70. The wide-mouth section 241 is used to limit the maximum opening angle of the air deflector 70. At the same time, when the air deflector 70 is opened upward or downward to the maximum angle, the wide-mouth section 241 can also avoid the second connecting rod 30, preventing the end of the sunk groove 24 of the first connecting rod 20 from hindering the relative movement between the first connecting rod 20 and the second connecting rod 30. Optionally, a direction-changing section 514 is provided at the ends of the second track groove 512 and the third track groove 513. The direction-changing section 514 is used to provide a movement space for the second slider 212 and the third slider 213 when the first connecting rod 20 swings along the rotation center, avoiding interference between the ends of the second track groove 512 and the third track groove 513 and the relative movement between the first connecting rod 20 and the second connecting rod 30.

[0070] Optionally, an avoidance portion is provided at the end of the first connecting rod 20, that is, as Figure 2 shown, avoidance portions are provided on both side surfaces of the first rotating shaft 23. During the relative movement between the first connecting rod 20 and the second connecting rod 30, the avoidance portion can prevent the second rotating shaft 32 from hindering the movement of the first connecting rod 20 and provide an avoidance space for the movement of the first connecting rod 20 relative to the second connecting rod 30.

[0071] The embodiment of the present disclosure further provides an air conditioner, including the above-described movement mechanism for the air deflector 70, as Figure 9 shown.

[0072] In some embodiments, the air conditioner includes a motion mechanism for the air deflector 70. The motion mechanism includes a housing, a crank 10, and a connecting rod assembly. The housing is provided with an avoidance opening. The crank 10 is disposed inside the housing and is used for driving connection with the driving element 60. The connecting rod assembly is slidably connected to the crank 10. A part of the connecting rod assembly is disposed inside the housing, and the end of the connecting rod assembly extends out from the avoidance opening and is rotatably connected to the air deflector 70. Wherein, the housing is used for defining the motion trajectories of the crank 10 and the connecting rod assembly, so that the air deflector 70 first translates and extends out of the air conditioner and then rotates.

[0073] During the movement of the air deflector 70, the housing is fixed to the air conditioner. Under the drive of the driving element 60, the crank 10 drives the connecting rod assembly to move, thereby opening or closing the air deflector 70.

[0074] The above description and the drawings fully illustrate the embodiments of the present disclosure, so that those skilled in the art can practice them. Other embodiments may include structural and other changes. The embodiments only represent possible variations.
