Benefits of technology

[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.

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 arc-shaped 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 arc-shaped 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 motor drives 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. In this way, the above-mentioned drive assembly can make an air guide plate open upwards, open downwards, or close. Furthermore, the structure of this drive assembly is simple, there is no gap between the air guide plate and the indoor unit of the air conditioner, and it is not easy for dust to accumulate.

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

[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 portion and a second tooth portion, the first tooth portion being used to mesh with the first driven gear, and the second tooth portion being used to mesh with the second driven gear; the rack and pinion connecting plate is connected to the air guide plate, and the rack and pinion connecting plate is provided with an arc-shaped rack that meshes with the first driven gear and the second driven gear; wherein, the main gear rotates in a first direction to open the air guide plate upward, and the main gear rotates in a second direction to open the air guide plate downward.

[0009] 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.

[0010] As the main gear rotates in the first direction, the first driven gear meshes from the first end of the first tooth to the second end, and the air guide plate opens upward.

[0011] As the main gear rotates in the second direction, the second driven gear meshes from the first end of the second tooth to the second end, and the air guide plate opens downward.

[0012] Optionally, the main gear further includes a common tooth portion disposed on the first circumferential surface and the second circumferential surface, the common tooth portion including the tooth portion between the first end of the first tooth portion and the first end of the second tooth portion.

[0014] Optionally, the rack connecting plate includes a rack portion, which includes a first rack and a second rack, wherein the first rack extends to one end of the rack connecting plate and the second rack extends to the other end of the rack connecting plate.

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

[0016] Optionally, the track section further includes a third track for the movement of the first driven gear and a fourth track 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 tooth of the second driven gear, causing the second driven gear to move in the fourth track and mesh with the second rack to rotate, while the first driven gear moves in the third track 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:

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 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 arc-shaped 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 motor drives 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. In this way, the above-mentioned drive assembly can make an air guide plate open upwards, open downwards, or close. Furthermore, the structure of this drive assembly is simple, there is no gap between the air guide plate and the indoor unit of the air conditioner, and it is not easy for dust to accumulate.

[0046] This application provides a driving assembly for an air guide plate, such as... Figures 1 to 4As shown. 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; 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 drivenly connected to the motor 10, the main gear 21 includes a first tooth 211 and a second tooth 212, the first tooth 211 is used to mesh with the first driven gear 22, and the second tooth 212 is used to mesh with the second driven gear 23; the rack and pinion connecting plate 30 is connected to the air guide plate 40, and the rack and pinion connecting plate 30 is provided with an arc-shaped rack that meshes with the first driven gear 22 and the second driven gear 23; wherein, the main gear 21 rotates in a first direction to open the air guide plate 40 upward, and the main gear 21 rotates in a second direction to open the air guide plate 40 downward.

[0047] In this embodiment of the application, the driving component 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 air guide plate 40 is closed, 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. Thus, the aforementioned drive assembly can open, close, or rotate an air guide plate 40. Furthermore, the drive assembly has a simple structure, and there is no gap between the air guide plate 40 and the indoor unit of the air conditioner, making it less prone to dust accumulation.

[0048] 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.

[0049] 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.

[0050] like Figure 1 and Figure 2 As 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.

[0051] As the main gear 21 rotates in the first direction, the first driven gear 22 meshes from the first end of the first tooth 211 to the second end, and the air guide plate 40 opens upward. In this way, the air guide plate 40 changes from a closed state to a state where it is opened upward to its maximum angle.

[0052] As the main gear 21 rotates in the second direction, the second driven gear 22 meshes from the first end of the second tooth 211 to the second end, and the air guide plate 40 opens downward. In this way, the air guide plate 40 changes from a closed state to a state where it is opened upward to its maximum angle.

[0053] 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 tooth portion between the first end of the first tooth portion 211 and the first end of the second tooth portion 212, such as... Figure 2 As shown. That is, when the air guide plate 40 is closed, the common tooth portion 213 is the tooth portion between the first driven gear 22 and the second driven gear 23.

[0054] like Figure 1As 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, the first end of the first tooth 211 of the common tooth portion 213 meshes with the first driven gear 22, and the first 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.

[0055] Optionally, the first driven gear 22 includes a third circumferential surface on which a first driven tooth portion 222 is provided; the second driven gear 23 includes a sixth circumferential surface on which a second driven tooth portion 232 is provided.

[0056] like Figure 2 As shown, the first driven tooth 222 is disposed on the third circumferential surface of the first driven gear 22, and the second driven tooth 232 is disposed on the sixth circumferential surface of the second driven gear 23. The third circumferential surface is the side away from the motor 10, and the sixth circumferential surface is the side closer to the motor 10. That is, when the air guide plate 40 is closed, the first driven tooth 222 of the first driven gear 22 meshes with the first tooth 211 of the main gear 21, and the second driven tooth 232 of the second driven gear 23 meshes with the second tooth 212 of the main gear 21. In this way, the gear set 20 can cooperate with the rack connecting plate 30 to open the air guide plate 40 upwards, downwards, and close it.

[0057] Optionally, the first driven gear 22 further includes a fourth circumferential surface that is toothless, and the second driven gear 23 further includes a fifth circumferential surface that is toothless. That is, both the first driven gear 22 and the second driven gear 23 are provided with toothless portions. This avoids the situation where, when the first driven gear 22 and the second driven gear 23 are not provided with toothless portions, both driven gears mesh with the common tooth portion 213 of the main gear 21, causing the main gear 21 to be unable to rotate, that is, the gear set 20 cannot drive the air guide plate 40 to rotate.

[0058] Optionally, when the air guide plate 40 is closed, the common tooth portion 213 of the main gear 21 is disposed between the first driven tooth portion 222 of the first driven gear 22 and the second driven tooth portion 232 of the second driven gear 23. For example... Figure 1 As shown, when the air guide plate 40 is closed, the common tooth 213 meshes with the first driven tooth 222 and the second driven tooth 232. This improves the meshing degree between the main gear 21 and the two driven gears and prevents the main gear 21 from disengaging from the two driven gears and causing the main gear 21 to spin idly.

[0059] 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 to one end of the rack connecting plate 30, and the second rack 312 extends to the other end of the rack connecting plate 30.

[0060] 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.

[0061] like Figure 2 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.

[0062] In this embodiment of the application, the first direction is defined as clockwise, and the second direction is defined as counterclockwise. For example... Figure 3 As shown, Figure 3 This 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.

[0063] like Figure 4 As shown, Figure 4 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.

[0064] In this embodiment, the gear set 20 is fixed to the housing 50 of the indoor unit of the air conditioner. That is, the positions of the main gear 21, the first driven gear 22, and the second driven gear 23 do not change during the upward or downward opening of the air guide plate 40. When the air guide plate 40 opens upward or downward, the rack connecting plate 30 connected to the air guide plate 40 needs to be provided with a track part 32, that is, a movement track for the first driven gear 22 and the second driven gear 23 needs to be provided. In this way, with the position of the gear set 20 fixed, the air guide plate 40 can be moved out of the indoor unit of the air conditioner to achieve upward or downward opening.

[0065] Optionally, the rack and pinion connecting plate 30 further includes a track portion 32, which includes a first track 321 for the movement of the first driven gear 22 and a second track 322 for the movement of the second driven gear 23. 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 321 and mesh with the first rack 311 to rotate. At the same time, the second driven gear 23 moves in the second track 322, and the air guide plate 40 opens downward.

[0066] like Figure 3As 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 321, and the second driven gear 23 moves within the second track 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 321, and the trajectory of the second driven gear 23 is the second track 322.

[0067] Optionally, the track section 32 further includes a third track 323 for the movement of the first driven gear 22 and a fourth track 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 324 and mesh with the second rack 312 to rotate, while the first driven gear 22 moves in the third track 323 and the air guide plate opens upward.

[0068] like Figure 4 As shown, when the main gear 21 rotates in the second direction, i.e., 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 324, and the first driven gear 22 moves in the third track 323. Thus, the air guide plate 40 changes from a closed state to an upward-opening state. Similarly, during the process of the air guide plate 40 changing from a closed state to an 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 trajectory of the first driven gear 22 is the third track 323, and the trajectory of the second driven gear 23 is the fourth track 324.

[0069] This application also provides an air guide plate 40, such as Figures 5 to 8 As shown.

[0070] In other embodiments, the air guide plate 40 includes an air guide plate body 41, a connecting portion, and a rack connecting plate 30. The connecting portion is disposed on the inner side wall of the air guide plate body 41. The rack connecting plate 30 is fixed to the inner side wall of the air guide plate body 41 through the connecting portion. The rack connecting plate 30 includes a rack portion 31 and a track portion 32. The rack portion 31 is provided with a rack, and the track portion 32 is provided with a track for the movement of the gear set 20 of the air conditioner. The rack connecting plate 30 is used to mesh with the gear set 20 through the rack.

[0071] An air guide plate 40 provided in this embodiment includes a rack and pinion connecting plate 30. The rack and pinion connecting plate 30 is fixed to the inner side wall of the air guide plate body 41 via a connecting part. The rack and pinion connecting plate 30 includes a rack portion 31 and a track portion 32. The rack portion 31 is provided with a rack for meshing with a gear set 20 fixed inside the air conditioner indoor unit. The track portion 32 is provided with a track for the movement of the gear set 20. Thus, the rack and pinion connecting plate 30 can mesh with the gear set 20 of the air conditioner via the rack, thereby driving the movement of the air guide plate 40. In this embodiment, the air guide plate 40 cooperating with the gear set 20 has a simple structure. Through the mutual cooperation between the air guide plate 40 and the gear set 20 of the air conditioner, the air guide plate 40 can be opened upwards, downwards, or closed, and it is less prone to malfunction.

[0072] In this embodiment of the application, the movement of the air guide plate 40, for example, the air guide plate 40 opening upward, opening downward, or closing, is the movement of the air guide plate body 41.

[0073] Optionally, the rack portion 31 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.

[0074] like Figure 6 As 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.

[0075] Optionally, the rack portion 31 further includes a first rack 311 and a second rack 312, wherein the first rack 311 is disposed on the first side of the first groove 313 and extends in an arc shape toward one end of the rack connecting portion, and the second rack 312 is disposed on the second side of the second groove 314 and extends in an arc shape toward the other end of the rack connecting portion.

[0076] 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 6As 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.

[0077] 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.

[0078] Optionally, the track section 32 includes a first track 321, a second track 322, a third track 323, and a fourth track 324 for the movement of the gear set 20. The gear set 20 includes a first driven gear 22 and a second driven gear 23. The first driven gear 22 is provided with a first driven tooth portion 222, and the second driven gear 23 is provided with a second driven tooth portion 232. The first track 321 and the third track 323 are the movement tracks of the first driven gear 22, and the second track 322 and the fourth track 324 are the movement tracks of the second driven gear 23.

[0079] like Figure 6 As shown, the rack and pinion connecting plate 30 also includes a track portion 32, the central region of which is provided with tracks, namely a first track 321, a second track 322, a third track 323, and a fourth track 324. Optionally, the gear set 20 includes a main gear 21, and a first driven gear 22 and a second driven gear 23 meshing with the main gear 21. The first driven gear 22 is provided with a first driven tooth portion 222, and the second driven gear 23 is provided with a second driven tooth portion 232. The first driven tooth portion 222 can mesh with the first rack 311 of the rack and pinion connecting plate 30, and the second driven tooth portion 223 can mesh with the second rack 312 of the rack and pinion connecting plate 30.

[0080] 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, the first driven gear 22 is positioned at the starting end of the first track 321 and the third track 323, and the second driven gear 23 is positioned at the starting end of the second track 322 and the fourth track 324. The starting ends of the first track 321 and the third track 323 coincide, and the starting ends of the second track 322 and the fourth track 324 coincide. When the air guide plate 40 is opened downward to its maximum angle, the first driven gear 22 is positioned at the second end of the first rack 311 and the end of the first track 321, and the second driven gear 23 is positioned at the end of the second track 322. When the air guide plate 40 is opened upward to its maximum angle, the first driven gear 22 is positioned at the end of the third track 323, and the second driven gear 23 is positioned at the end of the fourth track 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.

[0081] In this embodiment of the application, the first direction is defined as clockwise, and the second direction is defined as counterclockwise. For example... Figure 3 As 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 321, and the second driven gear 23 moves within the second track 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 321, and the trajectory of the second driven gear 23 is the second track 322. Figure 4As shown, when the main gear 21 rotates in the second direction, i.e., 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 324, and the first driven gear 22 moves in the third track 323. Thus, the air guide plate 40 changes from a closed state to an upward-opening state. Similarly, during the process of the air guide plate 40 changing from a closed state to an 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 trajectory of the first driven gear 22 is the third track 323, and the trajectory of the second driven gear 23 is the fourth track 324.

[0082] Optionally, the first track 321 is adjacent to the first rack 311, and the curvature of the first track 321 is the same as that of the first rack 311.

[0083] Optionally, a first rotating shaft 221 is provided at the center of the first driven gear 22, extending outward through both sides of the first driven gear 22. During the downward opening of the air guide plate 40, the first rack 311 meshes with the first driven teeth 222, and the first driven gear 22 moves within the first track 321. That is, the first rack 311 is the trajectory of the first driven teeth 222, and the first track 321 is the trajectory of the first rotating shaft 221. Thus, the curvature of the first track 321 is the same as the curvature of the first rack 311. Optionally, the length of the first rack 311 can be less than or equal to the length of the first track 321.

[0084] Optionally, the fourth track 324 is adjacent to the second rack 312, and the curvature of the fourth track 324 is the same as that of the first rack 311.

[0085] Optionally, a second rotating shaft 231 is provided at the center of the second driven gear 23, extending outward through both sides of the second driven gear 23. During the upward opening of the air guide plate 40, the second rack 312 meshes with the second driven tooth 232, and the second driven gear 23 moves within the fourth track 324. That is, the second rack 312 follows the movement trajectory of the second driven tooth 232, and the fourth track 324 follows the movement trajectory of the second rotating shaft 231. Thus, the curvature of the fourth track 324 is the same as the curvature of the second rack 312. Optionally, the length of the second rack 312 can be less than or equal to the length of the fourth track 324.

[0086] Optionally, the arc of the first rack 311 is the same as the arc of the second track 322, and the arc of the second rack 312 is the same as the arc of the third track 323.

[0087] 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 starting end of the first track 321 to the ending end of the first track 321, and the second driven gear 23 moves from the starting end of the second track 322 to the ending end of the second track 322. Figure 3 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 322, and the arc of the first rack 311 is also the same as the arc of the first track 321.

[0088] 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 324 to the end of the fourth track 324, and the first driven gear 22 moves from the beginning of the third track 323 to the end of the third track 323, as... Figure 4 As 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 323, and the arc of the second rack 312 is also the same as the arc of the fourth track 324.

[0089] Optionally, the rack connecting plate 30 is provided with a slider 33, which slides within a slide rail of the housing 50 of the gear set 20. Optionally, the number of sliders 33 is three, such as... Figure 7 As shown.

[0090] Optionally, the rack connecting plate 30 includes a first rack connecting plate and a second rack connecting plate, the first rack connecting plate being disposed at the first end of the inner sidewall of the air guide plate body 41; the second rack connecting plate being disposed at the second end of the inner sidewall of the air guide plate body 41.

[0091] Optionally, the bottom surface of the rack connecting plate 30 is provided with a connecting groove 34 that matches the connecting part 42. A connecting shaft 35 is provided in the connecting groove 34, and the rack connecting plate 30 is engaged with the connecting part 42 through the connecting shaft 35. Figure 8 As shown.

[0092] Optionally, the connecting part 42 includes a base 421 and a mounting part 422. The base 421 is fixed to the inner wall of the air guide plate body 41, and the mounting part 422 is disposed at the upper end of the base 421. The mounting part 422 and the base 421 can be an integral structure. The mounting part 422 is provided with a connection opening that matches the connecting shaft 35. The connection opening is used to engage with the connecting shaft 35. In this way, the rack connecting plate 30 can be fixed to the inner wall of the air guide plate body 41 through the connecting part 42, thereby improving the stability of the connection between the rack connecting plate 30 and the air guide plate body 41.

[0093] This application also provides a gearbox that matches the aforementioned air guide plate, such as... Figures 9 to 13 As shown.

[0094] 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.

[0095] The gearbox in this embodiment includes a motor 10, a gear set 20, and a housing 50. The gearbox is fixed inside the indoor unit of the air conditioner, and the motor 10 and gear set 20 are fixed inside the housing 50 of the gearbox. The position of the gearbox does not change during the movement of the air guide plate 40. The motor 10 is a bidirectional drive motor, meaning that the motor 10 can drive the main gear 21 to rotate along a first direction and a second direction. The gear set 20 includes a main gear 21, a first driven gear 22, and a second driven gear 23. The main gear 21 includes a first tooth portion 211 and a second tooth portion 212, wherein the first tooth portion 211 can mesh with the first driven gear 22, and the second tooth portion 212 can mesh with the second driven gear 23. When the air guide plate 40 is closed, when the motor 10 drives the main gear 21 to rotate in the first direction, the first tooth 211 of the main gear 21 meshes with the first driven gear 22, causing the first driven gear 22 to rotate in the second direction. The first driven gear 22 also meshes with the rack provided on the air guide plate 40, thereby driving the air guide plate 40 to mesh downward. When the air guide plate 40 changes from the downward open state to the closed state, the motor 10 drives the main gear 21 to rotate 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 provided on the air guide plate 40, driving the air guide plate 40 to close. Understandably, when the air guide plate 40 is closed, when the motor 10 drives the main gear 21 to rotate in the second direction, the second tooth 212 of the main gear 21 meshes with the second driven gear 23. The second driven gear 23, through meshing with the rack, drives the air guide plate 40 to open upwards. When the motor 10 drives the main gear 21 to rotate in the first direction, the air guide plate 40 changes from the upward-opening state back to the closed state. In this embodiment, a motor 10 can drive the main gear 21 in the first direction or the second direction to rotate an air guide plate 40. That is, through the interaction between the gear box and the rack disposed on the air guide plate 40, the air guide plate 40 can be opened upwards, opened downwards, or closed. Moreover, the gear box has a simple structure and is not prone to failure.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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 9 As 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 9 The air guide plate 40 is configured such that the upward opening angle and the downward opening angle are equal.

[0100] 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 10 As shown.

[0101] 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, and the first driven tooth portion 222 is disposed on the third circumferential surface of the first driven gear 22, while the toothless portion is 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 downwardly open state and from the downwardly open state back to a closed state, the first tooth portion 211 of the main gear 21 meshes with the first driven tooth portion 222.

[0102] 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, and the second driven tooth portion 232 is disposed on the sixth circumferential surface of the second driven gear 23, while the toothless portion is 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 upwardly open state and from an upwardly open state back to a closed state, the second tooth portion 212 of the main gear 21 meshes with the second driven tooth portion 232.

[0103] 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.

[0104] 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.

[0105] 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 10 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.

[0106] Optionally, the first driven gear 22 is provided with a first rotating shaft 221 that passes through both sides of the first driven gear 22 and extends outward; the second driven gear 23 is provided with a second rotating shaft 231 that passes through both sides of the second driven gear 23 and extends outward, wherein both ends of the first rotating shaft 221 and both ends of the second rotating shaft 231 are fixed inside the housing 50.

[0107] During the movement of the air guide plate 40, the position of the gear set 20 remains unchanged. Both ends of the first rotating shaft 221 extend outwards to the sides of the first driven gear 22, and both ends of the first rotating shaft 221 are fixed inside the housing 50. Similarly, both ends of the second rotating shaft 231 extend outwards to the sides of the second driven gear 23, and both ends of the second rotating shaft 231 are also fixed inside the housing 50. Figure 11 As shown. Optionally, the main gear 21 is driven to the motor 10 via a motor shaft, which extends through to the side of the main gear 21 opposite to the motor 10, but does not extend outward from that side.

[0108] Optionally, the housing 50 includes a first housing 51, which is provided with a first slot 511 for fixing one end of the first rotating shaft 221 and a second slot 512 for fixing one end of the second rotating shaft 231.

[0109] like Figure 12 As shown, the first housing 51 includes a motor recess for placing the motor 10. The side of the motor recess is provided with a first slot 511 and a second slot 512. The first slot 511 is used to fix one end of the first rotating shaft 221, and the second slot 512 is used to fix one end of the second rotating shaft 231. The first housing 51 is fixed to the air conditioner by screws or bolts.

[0110] Optionally, the housing 50 further includes a second housing 52, which is provided with a third slot 521 for fixing the other end of the first rotating shaft 221 and a fourth slot 522 for fixing the other end of the second rotating shaft 231, wherein the first housing 51 and the second housing 52 are disposed opposite to each other.

[0111] like Figure 11 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.

[0112] like Figure 13 As shown, Figure 13The inner surface of the second housing 52, opposite to the first housing 51, has a third slot 521 and a fourth slot 522 at its bottom. The third slot 521 is used to fix the other end of the first rotating shaft 221, and the fourth slot 522 is used to fix the other end of the second rotating shaft 231. Thus, both ends of the first rotating shaft 221 are fixed in the slots of the first housing 51 and the second housing 52, respectively, and both ends of the second rotating shaft 231 are also fixed in the slots of the first housing 51 and the second housing 52, respectively. The housing 50 is fixed inside the air conditioner, thereby fixing the positions of the first driven gear 22 and the second driven gear 23, preventing them from changing position with the movement of the air guide plate 40.

[0113] Optionally, the second housing 52 also includes a slide section for limiting the movement of the air guide plate 40.

[0114] like Figure 13 As shown, the second housing 52 is also provided with a slide section. The slide section matches the slider 33 on the side of the rack connecting plate 30. The slider 33 on the side of the rack connecting plate 30 can move in the slide section. In this way, the slide section can restrict the movement of the air guide plate 40 through the rack connecting plate 30.

[0115] Optionally, the slide section includes a first slide 523, a second slide 524, and a third slide 525. The first slide 523, the second slide 524, and the third slide 525 are all inverted V-shaped. The first end 5231 of the first slide 523 and the second end 5252 of the third slide 525 are both open ends, and the second end 5232 of the first slide 523 and the first end 5251 of the third slide 525 are both closed ends. Both ends of the second slide 524 are closed ends.

[0116] Optionally, the rack connecting plate 30 has three sliders 33 on its side: a first slider 331, a second slider 332, and a third slider 333. The first slider 331 moves along a first slide rail 523 on the second housing 52, the second slider 332 moves along a second slide rail 524 on the second housing 52, and the third slider 333 moves along a third slide rail 525 on the second housing 52. Figure 13 As shown, the first slide rail 523, the second slide rail 524, and the third slide rail 525 are all inverted V-shaped. The inverted V-shape includes a top and two sides connected to the top. The first end 5231 of the first slide rail 523 and the second end 5252 of the third slide rail 525 are both open ends, and the second end 5232 of the first slide rail 523 and the first end 5251 of the third slide rail 525 are both closed ends. Both ends of the second slide rail 524 are closed ends.

[0117] When the air guide plate 40 is closed, the first slider 331 is located at the top of the first slide rail 523, the second slider 332 is located at the top of the second slide rail 524, and the third slider 333 is located at the top of the third slide rail 525.

[0118] As the air guide plate 40 opens downward to its maximum angle, the first slider 331 moves from the top of the first slide rail 523 to the second end 5232 of the first slide rail 523, the second slider 332 moves from the top of the second slide rail 524 to the second end 5242 of the second slide rail 524, the third slider 333 moves from the top of the third slide rail 525 to the second end 5252 of the third slide rail 525 and slides out from the second end 5252 of the third slide rail 525, and the rack connecting plate 30 partially moves out of the housing 50 until it opens downward to its maximum angle.

[0119] As the air guide plate 40 opens upward to its maximum angle, the third slider 333 moves from the top of the third slide rail 525 to the first end 5251 of the third slide rail 525, the second slider 332 moves from the top of the second slide rail 524 to the first end 5241 of the second slide rail 524, the first slider 331 moves from the top of the first slide rail 523 to the first end 5231 of the first slide rail 523 and slides out from the first end 5231 of the first slide rail 523, and the rack connecting plate 30 partially moves out of the housing 50 until it opens upward to its maximum angle.

[0120] During the movement of the air guide plate 40, the first end 5231 of the first slide rail 523 and the second end 5252 of the third slide rail 525 are both open ends. In this way, the rack connecting part 42 can be partially moved out from the inside of the gear box housing 50, driving the air guide plate 40 to move. The second end 5232 of the first slide rail 523 and the first end 5251 of the third slide rail 525 are both closed ends, and both ends of the second slide rail 524 are both closed ends. In this way, the slider 33 can be limited, preventing the slider 33 from disengaging from the slide rail and causing the rack connecting plate 30 to deviate from the movement track.

[0121] This application also provides an air conditioning indoor unit, including the aforementioned drive assembly for the air guide vane. For example... Figure 14 As shown.

[0122] Figure 14 This diagram illustrates the state of the indoor unit of the air conditioner when the air guide plate 40 is opened downwards. The rack and pinion connecting plate 30 is fixed to the inner wall of the air guide plate body 41, and the motor 10 and gear set 20 are fixed inside the gearbox housing. During the movement of the air guide plate 40, the positions of the motor 10 and gear set 20 remain unchanged. Through the driving of the motor 10 along the first and second directions, and the cooperation of the aforementioned driving components, an air guide plate 40 can complete the process of opening upwards, opening downwards, and closing, meeting different airflow angle requirements. Furthermore, the driving component has a simple structure and is not prone to failure.
