[0042] Combine Figure 1-5 As shown, an embodiment of the present disclosure provides a driving mechanism for an air guide plate 50 .

[0043] In some embodiments, the driving mechanism for the air deflector 50 includes: a gear assembly 10, a driving element 20 and a rack plate 30, the gear assembly 10 is used to drive the air deflector 50 to open or close; the driving element 20 is used to drive the gear assembly 10; the rack plate 30 is provided with a first rack 31 and a second rack 32 that are meshed with the gear assembly 10, wherein the first rack 31 and the second rack 32 are staggered, when the gear assembly 10 is meshed with the first rack 31, the air deflector 50 opens downward, and when the gear assembly 10 is meshed with the second rack 32, the air deflector 50 opens upward.

[0044] Optionally, the driving element 20 may be a motor capable of driving the gear assembly 10 to rotate in both directions. The motor is drivingly connected to the gear assembly 10 and can drive the gear assembly 10 to rotate in the first direction or the second direction.

[0045] In the embodiment of this application, Figure 1 As shown, the first rack 31 is disposed on the first rack plate surface, and the second rack 32 is disposed on the second rack plate surface. The first rack 31 and the second rack 32 of the rack plate 30 are staggered. This staggered arrangement means that there is no rack at the position of the first rack on the second rack plate surface that corresponds to the first rack on the first rack plate surface. The first rack 31 and the second rack 32 are located at different heights and on different sides of the inner side surface of the rack plate 30, and both extend in the direction in which the air guide plate 50 translates out of the air conditioner. Thus, when the gear assembly 10 rotates in the first or second direction, the gear assembly 10 only engages with one rack of the rack plate 30. Alternatively, the first rack 31 is located at the bottom of the first rack plate surface, and the second rack 32 is located at the top of the second rack plate surface.

[0046] In the embodiment of the present application, the drive mechanism for the air deflector 50 includes a gear assembly 10, a drive element 20, and a rack plate 30. The gear assembly 10 is used to drive the air deflector 50 to open or close, the drive element 20 is used to drive the gear assembly 10, and the rack plate 30 is provided with a first rack 31 and a second rack 32 that mesh with the gear assembly 10. The first rack 31 and the second rack 32 are staggered. When the gear assembly 10 meshes with the first rack 31 of the rack plate 30, the air deflector 50 opens downward, and when the gear assembly 10 meshes with the second rack 32, the air deflector 50 opens upward. The drive element 20 can rotate the gear assembly 10 in a first direction or a second direction. The first rack 31 and the second rack 32 of the rack plate 30 are staggered, so that when the gear assembly 10 rotates in the first direction or the second direction, it only meshes with one rack of the rack plate 30. Thus, when the gear assembly 10 rotates in the first direction, the gear assembly 10 engages with the first rack 31 of the rack plate 30, causing the air deflector 50 to open downward from the closed state. At this time, when the gear assembly 10 rotates in the second direction while still engaging with the first rack 31 of the rack plate 30, the air deflector 50 returns from the downwardly opened state to the closed state. When the gear assembly 10 rotates in the second direction, the gear assembly 10 engages with the second rack 32 of the rack plate 30, causing the air deflector 50 to open upward from the closed state. At this time, when the gear assembly 10 rotates in the first direction while still engaging with the second rack 32 of the rack plate 30, the air deflector 50 returns from the upwardly opened state to the closed state. In this way, a single air deflector 50 can be opened upward, opened downward, or closed using a single drive mechanism. The structure of the drive mechanism is simple, reducing the failure rate of the drive mechanism.

[0047] Optionally, the gear assembly 10 includes: a main gear 11 and a first driven gear 12, the main gear 11 is drivingly connected to the driving element 20; the first driven gear 12 is used to be fixedly connected to the air guide plate 50 of the air conditioner, and drive the air guide plate 50 to open upward, open downward or close.

[0048] Alternatively, the drive element 20 may be a bidirectionally driven motor, which is drivably connected to the main gear 11, enabling the main gear 11 to rotate in both a first direction and a second direction. Alternatively, the main gear 11 may be directly engaged with the first driven gear 12, such that the rotation of the main gear 11 drives the rotation of the first driven gear 12. Furthermore, the first driven gear 12 is fixedly connected to the air deflector 50 of the air conditioner. Thus, the air deflector 50 can be opened upward, opened downward, or closed in response to the rotation of the first driven gear 12.

[0049] In the embodiment of the present application, when the air deflector 50 opens upward or downward, it moves in a trajectory that allows it to simultaneously rotate and extend toward the exterior of the air conditioner. The diameters of the main gear 11 and the first driven gear 12, as well as the lengths of the first rack 31 and the second rack 32 of the rack plate 30, influence the predetermined distance that the air deflector 50 extends from the air conditioner. The extension direction of the first rack 31 and the second rack 32 of the rack plate 30 determines the direction in which the air deflector 50 extends from the exterior of the air conditioner. The lengths of the first rack 31 and the second rack 32 are related to the diameters of the gears in the gear assembly 10. The predetermined distance that the air deflector 50 extends from the air conditioner is the distance that allows the air deflector 50 to simultaneously rotate and extend from the exterior of the air conditioner. If the diameters of the main gear 11 and the first driven gear 12 are too small, such that the distance that the air deflector 50 can be extended from the air conditioner is insufficient to meet the requirements for rotation, a transmission gear can be provided between the main gear 11 and the first driven gear 12 to ensure that the air deflector 50 extends from the air conditioner to the predetermined distance. Optionally, the number of transmission gears between the main gear 11 and the first driven gear 12 can be set according to a preset distance.

[0050] Optionally, the gear assembly 10 further includes a second driven gear 13, which is disposed between the main gear 11 and the first driven gear 12, and the second driven gear 13 is meshed with both the main gear 11 and the first driven gear 12. Figure 1 As shown, the main gear 11 rotates under the action of the driving element 20, and through the transmission engagement with the second driven gear 13, the first driven gear 12 can be rotated, thereby driving the air guide plate 50 to open upward, open downward or close.

[0051] Optionally, the main gear 11 includes a common tooth portion 114, which is located in a side-by-side position on the first circumferential surface, the second circumferential surface and the third circumferential surface of the main gear 11. The main gear 11 has a first circumferential surface, a second circumferential surface and a third circumferential surface. When the air guide plate 50 is closed, the common tooth portion 114 is located between the first rack 31 and the second rack 32, and the common tooth portion 114 is in a state of being engaged with the first rack 31 and the second rack 32.

[0052] Figure 3-1 and Figure 3-2This is a schematic diagram of the structure of the main gear 11 of the gear assembly 10 provided in an embodiment of the present application. When the air deflector 50 is closed, the common tooth portion 114 is located between the first rack 31 and the second rack 32, and the common tooth portion 114 is in a meshing state with the first rack 31 and the second rack 32. In this way, when the air deflector 50 is closed, there will be no disengaged teeth between the main gear 11 and the first rack 31 or the second rack 32, preventing the main gear 11 from idling due to the lack of meshing teeth with the first rack 31 or the second rack 32 during rotation, thereby preventing the air deflector 50 from being unable to move.

[0053] Optionally, the main gear 11 further includes a first tooth portion 111, the first tooth portion 111 is located on the first circumference and the third circumference of the main gear 11, and the first tooth portion 111 has the same position and the same length on the first circumference and the third circumference. Figure 3-1 and Figure 3-2 shown.

[0054] Optionally, the first tooth portion 111 extends from the first end of the common tooth portion 114 toward the direction of the second rack 32, wherein when the main gear 11 rotates along the first direction, the first rack 31 engages with the common tooth portion 114 and the first tooth portion 111 of the main gear 11 in sequence, and at the same time, the main gear 11 engages and rotates with the second driven gear 13, and the second driven gear 13 engages and rotates with the first driven gear 12, and the air guide plate 50 opens downward from the closed state.

[0055] In the embodiment of this application, Figure 2 As shown, the common tooth portion 114 of the main gear 11 has a first end and a second end. The first end is the end close to the second rack 32 when the air deflector 50 is in the closed state, and the second end is the end close to the first rack 31 when the air deflector 50 is in the closed state. Figure 2 The direction in which the middle main gear 11 rotates clockwise is a first direction, and the direction in which the main gear 11 rotates counterclockwise is a second direction.

[0056] like Figure 4 As shown, Figure 4This is a partial structural diagram of the drive mechanism when the air deflector 50 is opened downward to its maximum angle. The drive element 20 drives the main gear 11 to rotate in a first direction, that is, the main gear 11 rotates clockwise. The first rack 31 sequentially engages with the common tooth portion 114 and the first tooth portion 111 of the main gear 11. At the same time, the main gear 11 engages and rotates with the second driven gear 13, and the second driven gear 13 engages and rotates with the first driven gear 12, thereby causing the first driven gear 12 to drive the air deflector 50 downward from the closed state. During the downward opening process of the air deflector 50, only the main gear 11 engages with the first rack 31. Neither the first driven gear 12 nor the second driven gear 13 engages with the first rack 31 and the second rack 32. Optionally, the size of the second driven gear 13 can be adjusted to prevent the second driven gear 13 from engaging with the first rack 31 and the second rack 32. Optionally, the first driven gear 12 may be prevented from meshing with the first rack 31 and the second rack 32 by adjusting the positions of the first driven gear 12 and the rack plate 30 , or the size of the first driven gear 12 .

[0057] Optionally, the main gear 11 further includes a second tooth portion 112 , which is located on the second circumferential surface and the third circumferential surface of the main gear 11 , and has the same position and length on the second circumferential surface and the third circumferential surface.

[0058] Optionally, the second tooth portion 112 extends from the second end of the common tooth portion 114 toward the direction of the first rack 31, wherein when the main gear 11 rotates along the second direction, the second rack 32 engages with the common tooth portion 114 and the second tooth portion 112 of the main gear 11 in sequence, and at the same time, the main gear 11 engages and rotates with the second driven gear 13, and the second driven gear 13 engages and rotates with the first driven gear 12, and the air guide plate 50 opens upward from the closed state.

[0059] like Figure 5 As shown, Figure 5 This diagram shows a partial structural state of the drive mechanism when the air deflector 50 is opened upward to its maximum angle. The drive element 20 drives the main gear 11 to rotate in the second direction, i.e., counterclockwise. The second rack 32 sequentially engages with the common tooth portion 114 and the second tooth portion 112 of the main gear 11. Simultaneously, the main gear 11 meshes and rotates with the second driven gear 13, which in turn meshes and rotates with the first driven gear 12, thereby causing the first driven gear 12 to drive the air deflector 50 upward from the closed position. During the upward opening process of the air deflector 50, only the main gear 11 meshes with the second rack 32; neither the first driven gear 12 nor the second driven gear 13 meshes with the first rack 31 or the second rack 32.

[0060] Optionally, the main gear 11 further includes a third tooth portion 113, the third tooth portion 113 is located on the third circumference of the main gear 11, and the third tooth portion 113 is arranged between the first tooth portion 111 and the second tooth portion 112, as shown in FIG. Figure 3-1 When the air deflector 50 is opened upward or downward from a closed state, the third tooth portion 113 plays a role in transmission meshing with the second driven gear 13. If the third tooth portion 113 is toothless, the main gear 11 cannot maintain transmission meshing with the second driven gear 13 during rotation, that is, the air deflector 50 cannot be rotated to the maximum angle.

[0061] like Figure 3-1 and Figure 3-2 As shown, the main gear 11 includes a common tooth section 114, a first tooth section 111, a second tooth section 112, and a third tooth section 113. The main gear 11 has three circumferential surfaces: the first, second, and third circumferential surfaces. The common tooth sections 114 of the main gear 11 are arranged side by side on these three circumferential surfaces. When the air deflector 50 is closed, the tooth section between the first rack 31 and the second rack 32 constitutes the common tooth section 114 of the main gear 11. The first tooth section 111 is located on the first and third circumferential surfaces of the main gear 11, connected to the first end of the common tooth section 114, and has the same position and length on the first and third circumferential surfaces. The second tooth section 112 is located on the second and third circumferential surfaces of the main gear 11, connected to the second end of the common tooth section 114, and has the same position and length on the second and third circumferential surfaces. The third tooth portion 113 is located on the third circumferential surface of the main gear 11 and between the first tooth portion 111 and the second tooth portion 112 .

[0062] Optionally, the arc length of the first tooth portion 111 and the arc length of the second tooth portion 112 of the main gear 11 are the same, and the length of the first rack 31 must meet the meshing requirements of the first tooth portion 111 of the main gear 11, and the length of the second rack 32 must meet the meshing requirements of the second tooth portion 112 of the main gear 11. The vertical distance between the first rack 31 and the second rack 32 determines the arc length of the common tooth portion 114 of the main gear 11. In this way, the maximum upward opening angle of the air deflector 50 is equal to the maximum downward opening angle of the air deflector 50.

[0063] Optionally, the arc length of the first tooth portion 111 of the main gear 11 and the arc length of the second tooth portion 112 may also be different. When the length of the first rack 31 meets the meshing requirements of the first tooth portion 111 of the main gear 11 and the length of the second rack 32 meets the meshing requirements of the second tooth portion 112 of the main gear 11, the maximum angle of the air guide plate 50 opening upward is different from the maximum angle of the air guide plate 50 opening downward.

[0064] Optionally, both the first rack 31 and the second rack 32 are linear racks.

[0065] The air conditioner's gear assembly 10 is mounted between the first rack 31 and the second rack 32 of the rack plate 30. The extension direction of the first rack 31 and the second rack 32 influences the trajectory of the air deflector 50 as it extends outward from the air conditioner. Both the first rack 31 and the second rack 32 are linear racks. Thus, the trajectory of the air deflector 50 as it extends outward from the air conditioner is also linear. That is, the air deflector 50 can rotate while extending along the extension direction of the first rack 31 and the second rack 32. Furthermore, the length of the first rack 31 and the second rack 32, as well as the gear diameter of the gear assembly, influence the distance that the air deflector 50 extends outward from the air conditioner.

[0066] like Figure 2 As shown, the first rack 31 and the second rack 32 of the rack plate 30 are arranged in parallel, and the first rack plate surface and the second rack plate surface are also arranged in parallel. The first rack 31 is located at the lower part of the first rack plate surface, and the second rack 32 is located at the upper part of the second rack plate surface. Alternatively, the first rack 31 is located at the upper part of the first rack plate surface, and the second rack 32 is located at the lower part of the second rack plate surface, that is, the first rack 31 and the second rack 32 are staggered. In the embodiment of the present application, one side of the rack plate 30 is usually fixed to the air conditioner housing 60, the lower part of the first rack plate surface and the second rack plate surface is the position where the rack plate 30 is close to the air conditioner housing 60, and the upper part of the first rack plate surface and the second rack plate surface is the position where the rack plate 30 is away from the air conditioner housing 60.

[0067] Optionally, the rack plate 30 further includes a slide portion, which includes: a first slide 33 and a second slide 34, the first slide 33 is arranged on the first side of the first rack plate 31; the second slide 34 is arranged on the second side of the second rack plate surface.

[0068] Optionally, the first rack plate surface and the second rack plate surface are arranged opposite to each other, and the gear assembly 10 is installed between the first rack plate surface and the second rack plate surface. The other side of the first rack plate surface, that is, the first side, is used to set the first slide 33, and the other side of the second rack plate surface, that is, the second side, is used to set the second slide 34.

[0069] Optionally, the first slideway 33 is linear and arranged parallel to the first rack 31 ; the second slideway 34 is linear and arranged parallel to the second rack 32 .

[0070] like Figure 2As shown, the first slide 33 is linearly disposed on a first side portion of the first rack plate surface, parallel to the first rack 31. The second slide 34 is also linearly disposed on a second side portion of the second rack plate surface, parallel to the second rack 32. The first and second slides 33, 34 are used to mount the gear cover 40 that secures the gear assembly 10. During movement of the air deflector 50, the rack plate 30 is fixed to the air conditioner housing 60, and the gear assembly moves with the air deflector 50. The gear cover 40 also moves with the air deflector 50 and slides within the slide portion of the rack plate 30.

[0071] Optionally, a sliding sleeve is provided in the first slideway 33 and the second slideway 34 respectively, and the sliding sleeve is slidably connected to the first slideway 33 and the second slideway 34 .

[0072] Optionally, a sliding sleeve can be provided within the first slide 33, and a sliding sleeve can also be provided within the second slide 34. The sliding sleeves are slidably connected to the first slide 33 and the second slide 34, respectively, and have a certain friction force with the first slide 33 and the second slide 34. By providing a sliding sleeve within the sliding portion of the rack plate 30, the gear cover 40 can move more smoothly. Optionally, two sliding sleeves, namely a first sliding sleeve 351 and a second sliding sleeve 352, can also be provided within the first slide 33, and two sliding sleeves, namely a third sliding sleeve 353 and a fourth sliding sleeve 354, can also be provided within the second slide 34. By increasing the number of sliding sleeves within the first slide 33 and the second slide 34, the gear cover 40 can move at a uniform speed, thereby allowing the air deflector 50 to open or close smoothly.

[0073] Optionally, the rack plate 30 further includes fixing portions 36 , which are provided at both ends of the rack plate 30 and are used to fix the rack plate 30 to the air conditioner.

[0074] Optionally, the fixing portion 36 may be fixing holes provided at both ends of the rack plate 30 , and the rack plate 30 may be fixed to the housing 60 of the air conditioner by screws through the fixing holes.

[0075] The embodiment of the present application provides a wind deflector 50, such as Figure 6 shown.

[0076] In some embodiments, the air deflector 50 includes: an air deflector body 51 and a mounting base 52, the mounting base 52 is arranged on the inner side wall of the air deflector body 51, and the mounting base 52 is provided with a mounting hole 521, the mounting hole 521 is used to be fixedly connected to the driving mechanism that drives the air deflector body 51 to rotate, wherein the mounting base 52 is arranged at a preset position of the air deflector body 51, and the preset position is the position where the air deflector body 51 is completely located within the air supply range of the air outlet of the air conditioner when the air deflector body 51 is opened upward and downward to the maximum angle.

[0077] The air deflector 50 of the disclosed embodiment includes an air deflector body 51 and a mounting base 52. The mounting base 52 is disposed on the inner sidewall of the air deflector body 51. The mounting base 52 is provided with a mounting hole 521 for fixedly connecting to a driving mechanism that drives the air deflector body 51 to rotate. The mounting base 52 is disposed at a preset position on the inner sidewall of the air deflector body 51. When the air deflector body 51 is opened upward or downward to its maximum angle, the preset position enables the air deflector body 51 to be completely located within the air supply range of the air conditioner outlet. That is, when the air deflector body 51 is opened upward or downward to its maximum angle, both the inner and outer sidewalls of the air deflector body 51 are within the air supply range of the air conditioner outlet. In this way, when the air conditioner is cooling and supplying air, air flows through both the inner and outer sidewalls of the air deflector body 51, thereby preventing condensation from forming on the air deflector body 51.

[0078] Optionally, the preset position of the mounting seat 52 is a position close to the transverse center line of the air deflector body 51 .

[0079] like Figure 6 As shown, the horizontal center line of the air guide plate body 51 is Figure 6 The middle dotted line a in the figure is located close to the horizontal center line of the air guide body 51. Figure 6 The position of the mounting seat 52 can be within the range between the dotted lines on both sides of the dotted line a. Figure 6 Any position between the dotted line b and the dotted line c. Optionally, the area of the inner side wall of the air deflector body 51 between the dotted line b and the dotted line c is one-third of the total area of the inner side wall of the air deflector body 51. Optionally, the area of the inner side wall of the air deflector body 51 between the dotted line b and the dotted line c can also be one-quarter of the total area of the inner side wall of the air deflector body 51. Optionally, the preset position of the mounting seat 52 can also be set on the horizontal center line of the air deflector body 51, such as Figure 6 As shown. In the embodiment of the present application, the specific position of the mounting seat 52 needs to be set according to the position of the gear assembly in the drive mechanism that cooperates with the air deflector 50, the gear diameter of the gear assembly, and the opening angle of the air deflector 50. In the case where the gear diameter of the gear assembly is large, the air deflector 50 can extend a large distance from the air conditioner and can meet the maximum opening angle of the air deflector 50. The mounting seat 52 can be set at a position above or below the transverse center line of the air deflector body 51, that is, close to the dotted line b or the dotted line c. In the case where the gear diameter of the gear assembly is small, the air deflector body 51 can extend a small distance from the air conditioner, and the opening angle of the air deflector 50 will be correspondingly limited. The mounting seat 52 can be set on the transverse center line of the air deflector body 51. In this way, the opening angle of the air deflector body 51 can be met to the maximum extent, avoiding the edge of the air deflector 50 from abutting against the housing 60 of the air conditioner, causing condensation on the air deflector body 51 under cooling conditions.

[0080] Optionally, the shape of the mounting hole 521 is polygonal.

[0081] Optionally, the shape of the mounting hole 521 can be a triangle, a quadrilateral or a pentagon. In this way, the driving mechanism of the air deflector 50 can drive the air deflector 50 to rotate through the mounting hole 521, so that the air deflector 50 is opened or closed.

[0082] Optionally, the mounting hole 521 passes through the first side surface and the second side surface of the mounting seat 52 and is located at an upper portion of the mounting seat 52 .

[0083] like Figure 6 As shown, the mounting base 52 has a first side surface and a second side surface relative to each other, and the mounting hole 521 passes through the first side surface and the second side surface of the mounting base 52, and the mounting hole 521 is located at the upper part of the mounting base 52. In this way, it can avoid the situation where the mounting hole 521 is located in the middle or lower part of the mounting base 52, and the distance between the mounting hole 521 and the inner wall of the air deflector body 51 is small, so that the driving mechanism for the air deflector 50 cannot be connected to the air deflector body 51.

A connecting groove is provided at the center of the second side surface. The bottom of this connecting groove is located at the center of the first side surface and is used to mount the first positioning shaft 42 of the gear cover 40. In this way, the first driven gear 12 can be positioned through the gear cover 40, thereby cooperating with other components of the drive mechanism to drive the air deflector 50 to move.

[0088] Optionally, the second driven gear 13 has a third side surface and a fourth side surface that are opposite to each other, and a connecting hole that passes through the third side surface and the fourth side surface, and the connecting hole is used to connect to the second positioning shaft 43 of the gear cover 40. In this way, the positioning of the gear cover 40 can ensure that the first driven gear 12 and the second driven gear 13 remain in a meshed state even during the movement of the air deflector 50.

[0090] A sliding column 41 is provided at the end of the gear cover plate 40, and the sliding column 41 is installed in the sliding sleeve of the slide part of the rack plate 30; wherein, when the air guide plate 50 is opened upward and downward, the sliding column 41 slides from the first end to the second end of the slide part of the rack plate 30; when the air guide plate 50 is closed, the sliding column 41 slides from the second end to the first end of the slide part of the rack plate 30.

[0091] Optionally, sliding posts 41 are provided at both ends of the first side of the gear cover 40. The first side of the gear cover 40 serves as the side on which the gear assembly 10 is fixed. The number of sliding posts 41 provided on the first end of the gear cover 40 is the same as the number of sliding sleeves provided in the first slideway 33, and the number of sliding posts 41 provided on the second end of the gear cover 40 is the same as the number of sliding sleeves provided in the second slideway 34. Optionally, a first sliding post 411 and a second sliding post 412 are provided on the first end of the gear cover 40. The first sliding post 411 is mounted in the first sliding sleeve 351 of the first slideway 33, and the second sliding post 412 is mounted in the second sliding sleeve 352 of the first slideway 33.
