Description

Technical Field

[0001] This application relates to the field of air conditioning air guiding technology, such as a drive assembly for an air guide plate and an indoor air conditioning unit including the drive assembly. Background Technology

[0002] Air conditioning is an indispensable part of modern life, providing people with a suitable and comfortable living environment. Depending on the installation method, air conditioners can be divided into floor-standing air conditioners and wall-mounted air conditioners. Wall-mounted air conditioners use air guides to control the direction of airflow.

[0003] Currently, to achieve wider airflow angles, existing wall-mounted air conditioners generally use robotic arm-type air guides. A drive mechanism connected to the air guide pushes the guide out of the air conditioner body, allowing it to rotate. The guide rotates along the connecting axis of the robotic arm under the control of the motion mechanism, achieving airflow at different angles. Alternatively, the wall-mounted air conditioner has a larger gap between the air guide and the indoor unit, allowing the guide to rotate at a wider angle to meet users' needs for different airflow angles.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] When using a robotic arm-type air guide plate to adjust the airflow angle, the drive mechanism connected to the air guide plate has a complex structure and is prone to failure. Furthermore, when there is a large gap between the air guide plate and the indoor unit, dust can easily accumulate in the air duct of the indoor unit, failing to meet health requirements. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a drive assembly for an air guide vane and an indoor air conditioning unit to solve the problem of complex structure of the drive mechanism for the air guide vane.

[0008] In some embodiments, the drive assembly for the air guide plate includes: a motor, a gear set, and a rack and pinion connecting plate, wherein the motor is a bidirectional drive motor; the gear set includes a main gear, a first driven gear, and a second driven gear, the main gear being drivenly connected to the motor, the main gear including a first tooth and a second tooth, the first tooth being used to mesh with the first driven gear, and the second tooth being used to mesh with the second driven gear; the rack and pinion connecting plate is connected to the air guide plate, the rack and pinion connecting plate being provided with a rack that meshes with the first driven gear and the second driven gear, and a track that abuts against the first driven gear and the second driven gear; wherein the gear set is used to drive the air guide plate to open upward, open downward, or close.

[0009] Optionally, the rack connecting plate includes a track portion, a first driven gear is provided with a first rotating shaft passing through both sides of the first driven gear, and a second driven gear is provided with a second rotating shaft passing through both sides of the second driven gear. The first rotating shaft includes a first end extending outward to the first side of the first driven gear and a second end extending outward to the second side of the first driven gear. The second rotating shaft includes a third end extending outward to the third side of the second driven gear and a fourth end extending outward to the fourth side of the second driven gear. Both the first end and the third end of the first rotating shaft abut against the track portion.

[0010] Optionally, the length of the first end of the first rotating shaft is less than or equal to the length of the second end, and the length of the third end of the second rotating shaft is less than or equal to the length of the fourth end.

[0011] Optionally, the main gear has a first circumferential surface and a second circumferential surface, wherein a first tooth portion is disposed on the first circumferential surface and a second tooth portion is disposed on the second circumferential surface.

[0012] Optionally, the first driven gear includes a third circumferential surface with a first driven tooth portion and a fourth circumferential surface that is toothless.

[0013] Optionally, the second driven gear includes a sixth circumferential surface provided with a second driven tooth portion and a fifth circumferential surface provided with a toothless portion.

[0014] Optionally, the rack connecting plate includes a rack portion, which includes a first rack and a second rack. The first rack extends in an arc shape to one end of the rack connecting plate, and the second rack extends in an arc shape to the other end of the rack connecting plate.

[0015] Optionally, the track section includes a first track groove for the movement of the first driven gear and a second track groove for the movement of the second driven gear; wherein, when the main gear rotates along the first direction, the first tooth of the main gear meshes with the first driven gear, causing the first driven gear to move in the first track groove and mesh with the first rack to rotate, the second driven gear moves in the second track groove, and the air guide plate opens downward.

[0016] Optionally, the track section further includes a third track groove for the movement of the first driven gear and a fourth track groove for the movement of the second driven gear; wherein, when the main gear rotates along the second direction, the second tooth of the main gear meshes with the second driven gear, causing the second driven gear to move in the fourth track groove and mesh with the second rack to rotate, while the first driven gear moves in the third track groove, and the air guide plate opens upward.

[0017] In some embodiments, the indoor unit of the air conditioner includes the drive assembly for the air guide vane described above.

[0018] The drive assembly for the air guide plate and the indoor unit of the air conditioner provided in this disclosure can achieve the following technical effects:

[0019] In this embodiment, the driving assembly for the air guide plate includes a motor, a gear set, and a rack and pinion connecting plate. The rack and pinion connecting plate is connected to the air guide plate. During the movement of the air guide plate, the gear set and the motor are fixed inside the indoor unit of the air conditioner. The motor is a bidirectional drive motor, meaning it can drive the main gear in either a first direction or a second direction. When the air guide plate is closed, when the motor drives the main gear in the first direction, the main gear rotates in the first direction, and the first tooth of the main gear meshes with the first driven gear. The first driven gear rotates in the second direction and meshes with the rack of the rack and pinion connecting plate, causing the rack and pinion connecting plate to rotate in the first direction, thereby opening the air guide plate downwards. When the air guide plate changes from the downward-opening state to the closed state, the motor drives the main gear in the second direction, and the main gear rotates in the second direction. The first tooth of the main gear meshes with the first driven gear, and the first driven gear rotates in the first direction and meshes with the rack of the rack and pinion connecting plate, causing the rack and pinion connecting plate to rotate in the second direction, thereby closing the air guide plate. Understandably, when the air guide plate is closed, when the motor drives it in the second direction, the second tooth of the main gear meshes with the second driven gear, causing the air guide plate to open upwards. When the air guide plate changes from the upward-opening state to the closed state, the motor drives the main gear in the first direction, causing the air guide plate to close. During the above-mentioned movement of the air guide plate, the track of the rack connecting plate abuts against the first driven gear and the second driven gear. In this way, the above-mentioned drive assembly can make an air guide plate open upwards, open downwards, or close. Furthermore, the drive assembly has a simple structure, there is no gap between the air guide plate and the indoor unit of the air conditioner, and dust accumulation is not easy.

[0044] This application provides a driving assembly for an air guide plate, such as... Figures 1 to 7 As shown.

[0045] In some embodiments, the drive assembly for the air guide plate includes: a motor 10, a gear set 20, and a rack and pinion connecting plate 30, wherein the motor 10 is a bidirectional drive motor 10; the gear set 20 includes a main gear 21, a first driven gear 22, and a second driven gear 23, the main gear 21 being drivenly connected to the motor 10, the main gear 21 including a first tooth portion 211 and a second tooth portion 212, the first tooth portion 211 being used to mesh with the first driven gear 22, and the second tooth portion 212 being used to mesh with the second driven gear 23; the rack and pinion connecting plate 30 is connected to the air guide plate 40, the rack and pinion connecting plate 30 being provided with a rack that meshes with the first driven gear 22 and the second driven gear 23, and a track that abuts against the first driven gear 22 and the second driven gear 23; wherein the gear set 20 is used to drive the air guide plate 40 to open upward, open downward, or close.

[0046] In this embodiment, the driving assembly for the air guide plate 40 includes a motor 10, a gear set 20, and a rack and pinion connecting plate 30. The rack and pinion connecting plate 30 is connected to the air guide plate 40. During the movement of the air guide plate 40, the gear set 20 and the motor 10 are fixed inside the indoor unit of the air conditioner. The motor 10 is a bidirectional drive motor 10, that is, the motor 10 can drive the main gear 21 in a first direction or in a second direction. When the air guide plate 40 is closed, when the motor 10 drives the main gear 21 in the first direction, the main gear 21 rotates in the first direction, the first tooth 211 of the main gear 21 meshes with the first driven gear 22, the first driven gear 22 rotates in the second direction, and the first driven gear 22 meshes with the rack of the rack connecting plate 30, thereby driving the rack connecting plate 30 to rotate in the first direction, thus opening the air guide plate 40 downwards; when the air guide plate 40 changes from the downward opening state to the closed state, the motor 10 drives the main gear 21 in the second direction, the main gear 21 rotates in the second direction, the first tooth 211 of the main gear 21 meshes with the first driven gear 22, the first driven gear 22 rotates in the first direction, and the first driven gear 22 meshes with the rack of the rack connecting plate 30, thereby driving the rack connecting plate 30 to rotate in the second direction, thus closing the air guide plate 40. Understandably, when the motor 10 drives in the second direction, the second tooth 212 of the main gear 21 meshes with the second driven gear 23, causing the air guide plate 40 to open upwards; when the air guide plate 40 changes from the upward-opening state to the closed state, the motor 10 drives the main gear 21 in the first direction, causing the air guide plate 40 to close. During the above-mentioned movement of the air guide plate 40, the track of the rack connecting plate 30 abuts against the first driven gear 22 and the second driven gear 23. In this way, the above-mentioned drive assembly can make an air guide plate 40 open upwards, open downwards, or close. Furthermore, the structure of this drive assembly is simple, there is no gap between the air guide plate 40 and the indoor unit of the air conditioner, and dust is not easily accumulated.

[0047] Optionally, the rack connecting plate 30 includes a track portion 32. The first driven gear 22 is provided with a first rotating shaft 221 that passes through both sides of the first driven gear 22. The second driven gear 23 is provided with a second rotating shaft 231 that passes through both sides of the second driven gear 23. The first rotating shaft 221 includes a first end 2211 extending outward to the first side of the first driven gear 22 and a second end 2212 extending outward to the second side of the first driven gear 22. The second rotating shaft 231 includes a third end 2311 extending outward to the third side of the second driven gear 23 and a fourth end 2312 extending outward to the fourth side of the second driven gear 23. The first end 2211 of the first rotating shaft 221 and the third end 2311 of the second rotating shaft 231 both abut against the track portion 32.

[0048] In this embodiment, the first driven gear 22 has a first side and a second side, and the second driven gear 23 has a third side and a fourth side. The sides of the first driven gear 22 and the second driven gear 23 that are far from the motor 10 are defined as the first side and the third side, respectively. The sides of the first driven gear 22 and the second driven gear 23 that are close to the motor 10 are defined as the second side and the fourth side, respectively. Figure 1 As shown, the first end 2211 of the first rotating shaft 221 abuts against the track of the rack connecting plate 30, the second end 2212 of the first rotating shaft 221 extends toward one end of the motor 10, the third end 2311 of the second rotating shaft 231 abuts against the track of the rack connecting plate 30, and the fourth end 2312 of the second rotating shaft 231 extends toward one end of the motor 10.

[0049] Optionally, the length of the first end 2211 of the first rotating shaft 221 is less than or equal to the length of the second end 2212, and the length of the third end 2311 of the second rotating shaft 231 is less than or equal to the length of the fourth end 2312.

[0050] like Figure 2 As shown, Figure 2 The diagram shows the structure of the first driven gear 22. The length of the first end 2211 of the first rotating shaft 221 is less than the length of the second end 2212. It can be understood that the length of the third end 2311 of the second rotating shaft 231 is less than the length of the fourth end 2312. Optionally, the length of the first end 2211 of the first rotating shaft 221 can also be equal to the length of the second end 2212, and the length of the third end 2311 of the second rotating shaft 231 can also be equal to the length of the fourth end 2312.

[0051] Optionally, the main gear 21 has a first circumferential surface and a second circumferential surface, wherein a first tooth portion 211 is disposed on the first circumferential surface and a second tooth portion 212 is disposed on the second circumferential surface.

[0052] In the embodiments of this application, such as Figure 1 As shown, the motor 10 is connected to the main gear 21 via a drive shaft. The first circumferential surface of the main gear 21, the third circumferential surface of the first driven gear 22, and the fifth circumferential surface of the second driven gear 23 are defined as the circumferential surfaces away from the motor 10, while the second circumferential surface of the main gear 21, the fourth circumferential surface of the first driven gear 22, and the sixth circumferential surface of the second driven gear 23 are the circumferential surfaces close to the motor 10.

[0053] like Figure 1 and Figure 2As shown, the two teeth of the main gear 21 are disposed on different circumferential surfaces of the main gear 21, namely the first circumferential surface and the second circumferential surface. The first tooth 211 of the main gear 21 is disposed on the first circumferential surface, and the second tooth 212 of the main gear 21 is disposed on the second circumferential surface. In this way, the first tooth 211 can mesh with the first driven gear 22, and the second tooth 212 can mesh with the second driven gear 23. Through the cooperation of the two teeth of the main gear 21 with the two driven gears, the rack connecting plate 30 can drive the air guide plate 40 to open upward, open downward, or close.

[0054] Optionally, the main gear 21 further includes a common tooth portion 213 disposed on the first circumferential surface and the second circumferential surface, the common tooth portion 213 including a portion of the first tooth portion 211 and a portion of the second tooth portion 212.

[0055] like Figure 3 As shown, the main gear 21 is also provided with a common tooth portion 213, which is provided on both the first and second circumferential surfaces. When the air guide plate 40 is closed, one end of the first tooth 211 of the common tooth portion 213 meshes with the first driven gear 22, and one end of the second tooth 212 of the common tooth portion 213 meshes with the second driven gear 23. This prevents the main gear 21 from spinning freely due to its inability to mesh with the two driven gears, thus preventing the rack connecting plate 30 from driving the air guide plate 40 to rotate.

[0056] Optionally, the first driven gear 22 includes a third circumferential surface with a first driven tooth portion 222 and a fourth circumferential surface with a toothless portion. That is, the first driven gear 22 includes a toothed portion and a toothless portion, the toothed portion being the first driven tooth portion 222, which is disposed on the third circumferential surface of the first driven gear 22, and the toothless portion being disposed on the fourth circumferential surface of the first driven gear 22. During the process of the air guide plate 40 changing from a closed state to a downward-opening state and from a downward-opening state back to a closed state, the first tooth portion 211 of the main gear 21 meshes with the first driven tooth portion 222. In this embodiment, the meshing of the first tooth portion 211 of the main gear 21 with the first driven gear 22 is equivalent to the meshing of the first tooth portion 211 of the main gear 21 with the first driven tooth portion 222.

[0057] Optionally, the second driven gear 23 includes a sixth circumferential surface with a second driven tooth portion 232 and a fifth circumferential surface with a toothless portion. That is, the second driven gear 23 includes a toothed portion and a toothless portion, the toothed portion being the second driven tooth portion 232, which is disposed on the sixth circumferential surface of the second driven gear 23, and the toothless portion being disposed on the fifth circumferential surface of the second driven gear 23. During the process of the air guide plate 40 changing from a closed state to an upward-opening state and from an upward-opening state back to a closed state, the second tooth portion 212 of the main gear 21 meshes with the second driven tooth portion 232. In this embodiment, the meshing of the second tooth portion 212 of the main gear 21 with the second driven gear 23 is equivalent to the meshing of the second tooth portion 212 of the main gear 21 with the second driven tooth portion 232.

[0058] Optionally, the rack connecting plate 30 includes a rack portion 31, which includes a first rack 311 and a second rack 312. The first rack 311 extends in an arc shape to one end of the rack connecting plate 30, and the second rack 312 extends in an arc shape to the other end of the rack connecting plate 30.

[0059] In this embodiment, the first tooth 211 of the main gear 21 meshes with the first driven gear 22, that is, the first tooth 211 meshes with the first driven tooth 222 of the first driven gear 22. The second tooth 212 of the main gear 21 meshes with the second driven gear 23, that is, the second tooth 212 meshes with the second driven tooth 232 of the second driven gear 23. The first driven gear 22 meshes with the first rack 311, that is, the first driven tooth 222 of the first driven gear 22 meshes with the first rack 311. The second driven gear 23 meshes with the second rack 312, that is, the second driven tooth 232 of the second driven gear 23 meshes with the second rack 312.

[0060] like Figure 3 As shown, the rack connecting plate 30 includes a rack portion 31, which includes a first rack 311 and a second rack 312, both of which are arc-shaped. In this embodiment, the end of the first rack 311 near the bottom of the rack connecting plate 30 is defined as the first end of the first rack 311, and the end of the second rack 312 near the bottom of the rack connecting plate 30 is defined as the first end of the second rack 312. When the air guide plate 40 is closed, the first driven gear 22 meshes with the first end of the first rack 311, and the second driven gear 23 meshes with the first end of the second rack 312.

[0061] In this embodiment of the application, the first direction is defined as clockwise, and the second direction is defined as counterclockwise. For example... Figure 4 As shown, Figure 4This is a schematic diagram of the drive assembly when the air guide plate 40 is opened downwards. When the motor 10 drives the main gear 21 clockwise, the main gear 21 rotates in the clockwise direction. The first tooth 211 of the main gear 21 meshes with the first driven tooth 222, thereby driving the first driven gear 22 to rotate counterclockwise. The first driven tooth 222 meshes with the first rack 311, thereby driving the first rack 311 to rotate in the clockwise direction. That is, the air guide plate 40 changes from the closed state to the downward-open state. When the air guide plate 40 changes from the downward open state to the closed state, the motor 10 drives the main gear 21 counterclockwise. The main gear 21 rotates counterclockwise, and the first tooth 211 of the main gear 21 meshes with the first driven tooth 222, thereby driving the first driven gear 22 to rotate clockwise. The first driven tooth 222 meshes with the first rack 311, thereby driving the first rack 311 to rotate counterclockwise. When the first driven tooth 222 meshes with the first end of the first rack 311, the air guide plate 40 closes.

[0062] like Figure 5 As shown, Figure 5 This is a schematic diagram of the drive assembly when the air guide plate 40 is opened upwards. When the motor 10 drives the main gear 21 counterclockwise, the main gear 21 rotates in the counterclockwise direction. The second tooth 212 of the main gear 21 meshes with the second driven tooth 232, thereby driving the second driven gear 23 to rotate clockwise. The second driven tooth 232 meshes with the second rack 312, thereby driving the second rack 312 to rotate in the counterclockwise direction. That is, the air guide plate 40 changes from the closed state to the open state. When the air guide plate 40 changes from the upward open state to the closed state, the motor 10 drives the main gear 21 clockwise. The main gear 21 rotates clockwise, and the second tooth 212 of the main gear 21 meshes with the second driven tooth 232, thereby driving the second driven gear 23 to rotate counterclockwise. The second driven tooth 232 meshes with the second rack 312, thereby driving the second rack 312 to rotate clockwise. When the second driven tooth 232 meshes with the first end of the second rack 312, the air guide plate 40 closes.

[0063] Optionally, the track section 32 includes a first track groove 321 for the movement of the first driven gear 22 and a second track groove 322 for the movement of the second driven gear 23; wherein, when the main gear 21 rotates in the first direction, the first tooth 211 of the main gear 21 meshes with the first driven tooth 222 of the first driven gear 22, causing the first driven gear 22 to move in the first track groove 321 and mesh with the first rack 311 to rotate, while the second driven gear 23 moves in the second track groove 322, and the air guide plate 40 opens downward.

[0064] like Figure 4As shown, when the main gear 21 rotates in the first direction, i.e., clockwise, the first tooth 211 of the main gear 21 meshes with the first driven tooth 222. The first driven gear 22 moves within the first track groove 321, and the second driven gear 23 moves within the second track groove 322. Thus, the air guide plate 40 changes from a closed state to a downward-opening state. During this process, the first driven gear 22 and the second driven gear 23 do not change position. Both move relative to the rack connecting plate 30. The trajectory of the first driven gear 22 is the first track groove 321, and the trajectory of the second driven gear 23 is the second track groove 322.

[0065] Optionally, the track section 32 further includes a third track groove 323 for the movement of the first driven gear 22 and a fourth track groove 324 for the movement of the second driven gear 23; wherein, when the main gear 21 rotates in the second direction, the second tooth 212 of the main gear 21 meshes with the second driven tooth 232 of the second driven gear 23, causing the second driven gear 23 to move in the fourth track groove 324 and mesh with the second rack 312 to rotate, while the first driven gear 22 moves in the third track groove 323 and the air guide plate opens upward.

[0066] like Figure 5 As shown, when the main gear 21 rotates in the second direction, that is, when the main gear 21 rotates counterclockwise, the second tooth 212 of the main gear 21 meshes with the second driven tooth 232. The second driven gear 23 moves in the fourth track groove 324, and the first driven gear 22 moves in the third track groove 323. In this way, the air guide plate 40 changes from the closed state to the upward opening state. Similarly, during the process of the air guide plate 40 changing from the closed state to the upward opening state, the first driven gear 22 and the second driven gear 23 themselves do not change position. Both the first driven gear 22 and the second driven gear 23 move relative to the rack connecting plate 30. The movement trajectory of the first driven gear 22 is the third track groove 323, and the movement trajectory of the second driven gear 23 is the fourth track groove 324.

[0067] Optionally, the rack portion 31 further includes a first groove 313 and a second groove 314, wherein the first groove 313 is used to accommodate the first driven gear 22 and the second groove 314 is used to accommodate the second driven gear 23.

[0068] like Figure 6As shown, the rack portion 31 of the rack connecting plate 30 is provided with a first groove 313 and a second groove 314. When the air guide plate 40 is in the closed state, the first groove 313 is used to accommodate the first driven gear 22, and the second groove 314 is used to accommodate the second driven gear 23. In this way, the teeth of the first driven gear 22 and the second driven gear 23 can maintain a stable meshing state with the main gear 21 and the rack of the rack connecting plate 30 when the air guide plate 40 is closed, so that the air guide plate 40 can be opened or closed smoothly.

[0069] Optionally, the first rack 311 is disposed on the first side of the first groove 313, and the second rack 312 is disposed on the second side of the second groove 314.

[0070] In this embodiment of the application, the first side of the first groove 313 is defined as the side of the first groove 313 near the end of the rack connecting plate 30, and the second side of the second groove 314 is defined as the side of the second groove 314 near the other end of the rack connecting plate 30, such as... Figure 6 As shown. The first rack 311 is disposed on the first side of the first groove 313, and the second rack 312 is disposed on the second side of the second groove 314. In this way, when the air guide plate 40 is in the closed state and during the process of the air guide plate 40 opening upward or downward, the teeth of the first driven gear 22 can maintain a good meshing state with the first rack 311, and the teeth of the second driven gear 23 can also maintain a good meshing state with the second rack 312, so that the air guide plate 40 can be stably opened or closed.

[0071] Optionally, the first groove 313 and the second groove 314 are disposed between the first rack 311 and the second rack 312. In this way, when the air guide plate 40 is closed, the first driven gear 22 and the second driven gear 23 are located between the first rack 311 and the second rack 312, and can maintain good meshing with the rack of the rack connecting plate 30.

[0072] In this embodiment of the application, the end of the first rack 311 near the bottom of the rack connecting plate 30 is defined as the first end of the first rack 311, and the end away from the bottom of the rack connecting plate 30 is defined as the second end of the first rack 311. The end of the second rack 312 near the bottom of the rack connecting plate 30 is defined as the first end of the second rack 312, and the end away from the bottom of the rack connecting plate 30 is defined as the second end of the second rack 312. When the air guide plate 40 is closed, defined as the closed state, the position of the first driven gear 22 is the starting end of the first track groove 321 and the third track groove 323, and the position of the second driven gear 23 is the starting end of the second track groove 322 and the fourth track groove 324, wherein the starting ends of the first track groove 321 and the third track groove 323 coincide, and the starting ends of the second track groove 322 and the fourth track groove 324 coincide. Defined as the air guide plate 40 opening downward to the maximum angle, the position of the first driven gear 22 is the second end of the first rack 311 and the end of the first track groove 321, and the position of the second driven gear 23 is the end of the second track groove 322. Defined as the air guide plate 40 opening upward to the maximum angle, the position of the first driven gear 22 is the end of the third track groove 323, and the position of the second driven gear 23 is the end of the fourth track groove 324 and the second end of the second rack 312. With the air guide plate 40 closed, the first driven gear 22 and the second driven gear 23 are located at the bottom of the rack portion 31. The first driven gear 222 meshes with the first end of the first rack 311, and the second driven gear 232 meshes with the first end of the second rack 312.

[0073] Optionally, the arc of the first rack 311 is the same as the arc of the second track groove 322, and the arc of the second rack 312 is the same as the arc of the third track groove 323.

[0074] During the downward opening of the air guide plate 40, the first driven gear 222 continuously meshes with the first rack 311. The first driven gear 22 moves from the beginning of the first track groove 321 to the end of the first track groove 321, and the second driven gear 23 moves from the beginning of the second track groove 322 to the end of the second track groove 322. Figure 4 As shown. Therefore, the motion trajectories of the first driven gear 22 and the second driven gear 23 are concentric circles, that is, the arc of the first rack 311 is the same as the arc of the second track groove 322, and the arc of the first rack 311 is also the same as the arc of the first track groove 321.

[0075] During the upward opening of the air guide plate 40, the second driven gear 232 continuously meshes with the second rack 312, the second driven gear 23 moves from the beginning of the fourth track groove 324 to the end of the fourth track groove 324, and the first driven gear 22 moves from the beginning of the third track groove 323 to the end of the third track groove 323, as... Figure 5As shown. Therefore, the motion trajectories of the second driven gear 23 and the first driven gear 22 are concentric circles, that is, the arc of the second rack 312 is the same as the arc of the third track groove 323, and the arc of the second rack 312 is also the same as the arc of the fourth track groove 324.

[0076] Optionally, the rack and pinion connecting plate 30 is provided with a slide rail 33 on its side, which is used to cooperate with the slider 521 in the indoor unit of the air conditioner and to restrict the movement of the air guide plate 40.

[0077] Optionally, the slide section 33 includes a first slide groove 331 and a second slide groove 332. The first slide groove 331 has a first end and a second end extending toward one end of the rack connecting plate 30, and the second slide groove 332 has a first end and a second end extending toward the other end of the rack connecting plate 30, wherein the first end of the first slide groove 331 and the first end of the second slide groove 332 coincide.

[0078] In this embodiment of the application, the end of the first slide groove 331 near the bottom of the rack connecting plate 30 is defined as the first end of the first slide groove 331, the end of the second slide groove 332 near the bottom of the rack connecting plate 30 is defined as the first end of the second slide groove 332, the end of the first slide groove 331 away from the bottom of the rack connecting plate 30 is defined as the second end of the first slide groove 331, and the end of the second slide groove 332 away from the bottom of the rack connecting plate 30 is defined as the second end of the second slide groove 332, wherein the first end of the first slide groove 331 and the second end of the second slide groove 332 coincide.

[0079] like Figure 7 As shown, the rack connecting plate 30 has a slide section 33 on its side. The slide section 33 is an inverted "V"-shaped groove. The first slide groove 331 is arc-shaped and located on one side of the inverted "V"-shaped groove, and the second slide groove 332 is arc-shaped and located on the other side of the inverted "V"-shaped groove. This inverted "V"-shaped groove can match the slider 521 of the gear box housing 50 described below, allowing the slider 521 to slide within the slide section 33.

[0080] This application also provides a gearbox that matches the air guide plate, such as... Figures 8 to 11 As shown.

[0081] In other embodiments, the gearbox includes a motor 10, a gear set 20, and a housing 50. The motor 10 is a bidirectional drive motor. The gear set 20 includes a main gear 21, a first driven gear 22, and a second driven gear 23. The main gear 21 is driven by the motor 10 and includes a first tooth 211 and a second tooth 212. The first tooth 211 meshes with the first driven gear 22, and the second tooth 212 meshes with the second driven gear 23. The housing 50 is used to fix the motor 10 and the gear set 20. The first driven gear 22 and the second driven gear 23 mesh with a rack disposed on the air guide plate 40 to drive the air guide plate 40 to rotate.

[0082] Optionally, the main gear 21 has a first circumferential surface and a second circumferential surface, wherein a first tooth portion 211 is disposed on the first circumferential surface and a second tooth portion 212 is disposed on the second circumferential surface.

[0083] Optionally, the portion of the first circumferential surface in which the first tooth 211 is provided is less than or equal to half of the total circumferential surface of the first circumferential surface, and the portion of the second circumferential surface in which the second tooth 212 is provided is less than or equal to half of the total circumferential surface of the second circumferential surface.

[0084] Optionally, the portion of the first circumferential surface with the first tooth 211 is smaller than half the total circumferential surface of the first circumferential surface, and the portion of the second circumferential surface with the second tooth 212 is smaller than half the total circumferential surface of the second circumferential surface. That is, the arc length corresponding to the first tooth 211 on the first circumferential surface is smaller than the arc length corresponding to the toothless portion on the first circumferential surface, and the arc length corresponding to the second tooth 212 on the second circumferential surface is smaller than the arc length corresponding to the toothless portion on the second circumferential surface. When the circumferential portion of the first tooth 211 on the first circumferential surface is greater than half of the total circumferential surface of the first circumferential surface, and the circumferential portion of the second tooth 212 on the second circumferential surface is greater than half of the total circumferential surface of the second circumferential surface, during the rotation of the main gear 21 in the first direction, the first driven gear 22 does not mesh with the end of the first tooth 211, and the second driven gear 23 will mesh with the second tooth 212. The first tooth 211 and the second tooth 212 of the main gear 21 are both subjected to meshing force, causing the main gear 21 to be unable to rotate. The gear set 20 cannot mesh with the rack on the air guide plate 40 to drive the air guide plate 40 to rotate.

[0085] Optionally, the portion of the first circumferential surface in which the first tooth 211 is provided may be equal to half of the total circumferential surface of the first circumferential surface, and the portion of the second circumferential surface in which the second tooth 212 is provided may be equal to half of the total circumferential surface of the second circumferential surface. Both the total circumferential surface of the first and second circumferential surfaces are the circumferential surfaces of the main gear; that is, the portion of the first tooth 211 is equal to the portion of the second tooth 212, as shown below. Figure 8As shown. The upward and downward opening angles of the air guide plate 40 are related to the circumferential surface of the first tooth 211 and the circumferential surface of the second tooth 212 of the main gear 21, as well as the length and curvature of the rack. When the length and curvature of the rack on the air guide plate 40 meet the meshing requirements of the first driven gear 22 or the second driven gear 23, the first tooth 211 and the second tooth 212 of the main gear 21 satisfy the above-mentioned requirements. Figure 8 The air guide plate 40 is configured such that the upward opening angle and the downward opening angle are equal.

[0086] Optionally, the main gear 21 further includes a common tooth portion 213 disposed on the first and second circumferential surfaces. The common tooth portion 213 includes a portion of the teeth of the first tooth portion 211 and a portion of the teeth of the second tooth portion 212, such as... Figure 8 As shown.

[0087] Optionally, the first driven gear 22 includes a third circumferential surface provided with a first driven tooth portion 222, and a fourth circumferential surface provided with a toothless portion.

[0088] Optionally, the second driven gear 23 includes a sixth circumferential surface provided with a second driven tooth portion 232, and a fifth circumferential surface provided with a toothless portion.

[0089] Optionally, the thickness of the first driven tooth 222 is equal to the thickness of the first tooth 211 of the main gear 21. This ensures that the first driven tooth 222 meshes well with the first tooth 211 of the main gear 21, preventing the first driven tooth 222 from disengaging from the first tooth 211 of the main gear 21 during rotation.

[0090] Optionally, the thickness of the second driven tooth 232 is equal to the thickness of the second tooth 212 of the main gear 21. This allows the second driven tooth 232 to mesh well with the second tooth 212 of the main gear 21, preventing the second driven tooth 232 from disengaging from the second tooth 212 of the main gear 21 during rotation.

[0091] Optionally, the thickness of the first driven tooth portion 222 can be equal to the thickness of the second driven tooth portion 232, that is, the thickness of the first tooth portion 211 of the main gear 21 is equal to the thickness of the second tooth portion 212, such as... Figure 8 As shown. In this way, when the main gear 21 rotates in the first direction or in the second direction, the first tooth 211 can maintain good meshing with the first driven tooth 222, or the second tooth 212 can also maintain good meshing with the second driven tooth 232.

[0092] Optionally, the first driven gear 22 is provided with a first rotating shaft 221 extending through both sides of the first driven gear 22, and the second driven gear 23 is provided with a second rotating shaft 231 extending through both sides of the second driven gear 23. The first rotating shaft 221 includes a first end 2211 extending outward to the first side of the first driven gear 22, and a second end 2212 extending outward to the second side of the first driven gear 22. The second rotating shaft 231 includes a third end 2311 extending outward to the third side of the second driven gear 23, and a fourth end 2312 extending outward to the fourth side of the second driven gear 23. Both the first end 2211 of the first rotating shaft 221 and the third end 2311 of the second rotating shaft 231 abut against the track portion 32. Both the second end 2212 of the first rotating shaft 221 and the fourth end 2312 of the second rotating shaft 231 are fixed within the housing 50.

[0093] Optionally, the length of the first end 2211 of the first rotating shaft 221 is less than or equal to the length of the second end 2212, and the length of the third end 2311 of the second rotating shaft 231 is less than or equal to the length of the fourth end 2312.

[0094] Optionally, the housing 50 includes a first housing 51, which is provided with a first slot 511 for fixing the second end 2212 of the first rotating shaft 221 and a second slot 512 for fixing the fourth end 2312 of the second rotating shaft 231.

[0095] like Figure 9 As shown, the first housing 51 includes a motor recess for placing the motor 10. A first slot 511 and a second slot 512 are provided on the side of the motor recess. The first slot 511 is used to fix the second end 2212 of the first rotating shaft 221, and the second slot 512 is used to fix the fourth end 2312 of the second rotating shaft 231. The first housing 51 is fixed to the air conditioner by screws or bolts.

[0096] Optionally, the housing 50 further includes a second housing 52, wherein the first housing 51 and the second housing 52 are disposed opposite to each other.

[0097] like Figure 10 As shown, the gearbox housing 50 comprises two parts: a first housing 51 and a second housing 52. The first housing 51 and the second housing 52 are arranged opposite to each other and are fixedly connected by bolts or screws. The bottom of the housing 50 has an open structure for accommodating the rack connecting plate 30 connected to the air guide plate 40, and this open structure allows the rack connecting plate 30 to move upward or downward.

[0098] Optionally, a slider 521 is provided on the side of the second housing 52, which is used to limit the movement of the rack connecting plate 30. Optionally, there is one slider 521.

[0099] Optionally, the side of the rack connecting plate 30 is provided with a slide section 33, which includes a first slide groove 331 and a second slide groove 332. The first slide groove 331 has a first end and a second end extending to one end of the rack connecting plate 30, and the second slide groove 332 has a first end and a second end extending to the other end of the rack connecting plate 30, wherein the first end of the first slide groove 331 and the first end of the second slide groove 332 coincide.

[0100] like Figure 11 As shown, Figure 11 The inner side of the second housing 52, which is opposite to the first housing 51, is provided with a slider 521. The slider 521 can cooperate with the slide section 33 on the side of the rack connecting plate 30 to restrict the movement of the rack connecting plate 30.

[0101] In this embodiment, during the movement of the air guide plate 40, the position of the gear box remains unchanged. The rack connecting plate 30 is connected to the air guide plate 40 and moves with it. That is, the slider 521 disposed on the housing 50 and the slide rail portion 33 of the rack connecting plate 30 move relative to each other. When the air guide plate 40 is in the closed state, the slider 521 is located at the first end of the first slide groove 331, which is also the first end of the second slide groove 332. When the air guide plate 40 is opened downward from the closed state, the slider 521 slides from the first end of the first slide groove 331 to the second end of the first slide groove 331. When the slide groove reaches the second end of the first slide groove 331, the air guide plate 40 opens downward to its maximum angle. When the air guide plate 40 changes from the downward opening state back to the closed state, the slider 521 slides from the second end of the first slide groove 331 to the first end of the first slide groove 331. When the slider 521 reaches the first end of the first slide groove 331, the air guide plate 40 returns to the closed state. As the air guide plate 40 opens upwards from the closed state, the slider 521 slides from the first end of the second groove 332 to the second end of the second groove 332. When the slider 521 reaches the second end of the second groove 332, the air guide plate 40 opens upwards to its maximum angle. When the air guide plate 40 changes back to the closed state from the upward opening state, the slider 521 slides from the second end of the second groove 332 to the first end of the second groove 332. When the slider 521 reaches the first end of the second groove 332, the air guide plate 40 returns to the closed state. That is, the first groove 331 represents the movement trajectory of the slider 521 during the process of the air guide plate 40 changing from the closed state to the downward opening state and from the downward opening state to the closed state; the second groove 332 represents the movement trajectory of the slider 521 during the process of the air guide plate 40 changing from the closed state to the upward opening state and from the upward opening state to the closed state.

[0102] This application also provides an air conditioner indoor unit, including the aforementioned drive assembly for the air guide plate 40, such as... Figure 12 As shown.

[0103] In other embodiments, the indoor unit of the air conditioner includes the aforementioned drive assembly for the air guide plate 40, wherein the motor 10 and the gear set 20 are fixed inside the housing of the gearbox, and the positions of the motor 10 and the gear set 20 do not change during the movement of the air guide plate 40. Through the driving of the motor 10 along the first and second directions, and the cooperation of the aforementioned drive assembly, an air guide plate 40 can complete the process of opening upwards, opening downwards, and closing, meeting different airflow angle requirements. Furthermore, the drive assembly has a simple structure and is not prone to failure.
