Abstract

This application relates to the field of air conditioning technology and discloses a driving assembly for an air guide plate, comprising: a gear; a motor for driving the gear; and a rack and pinion connecting plate for connecting to the air guide plate. The rack and pinion connecting plate includes a first rack and a second rack, with the gear located between the first and second racks. The gear can drive either the first or second rack. Both the first and second racks are arc-shaped structures. When the gear drives the first rack, the first rack rotates about its arc center, causing the air guide plate to be in an upward-opening state. When the gear drives the second rack, the second rack rotates about its arc center, causing the air guide plate to be in a downward-opening state. This application can achieve both upward and downward opening states of the air guide plate using only one driving mechanism, enabling large-angle rotation without creating noticeable gaps that would affect the use of the air conditioner. This application also discloses an air conditioner indoor unit.

Description

Technical Field

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

[0002] To achieve a wider airflow angle adjustment, existing air conditioner air deflectors typically employ the following two solutions:

[0003] The first approach involves leaving a large gap between the air guide plate and the air conditioner to allow the plate to rotate. However, this approach is limited by the air duct, restricts the plate's rotation, and the large gap affects aesthetics and does not prevent dust accumulation, leading to dust buildup inside the air conditioning duct and failing to meet health requirements.

[0004] The second approach uses a robotic arm-type large guide plate. A motion mechanism moves the entire guide plate out of the unit, and then the guide plate rotates along its connecting axis to the robotic arm under the control of the motion mechanism, allowing for large-angle rotation. However, this approach requires at least two sets of motion mechanisms to extend and rotate the guide plate. The increased number of mechanisms raises the cost of the air conditioner, and also increases the probability of malfunction, resulting in lower reliability of the guide plate's movement. Summary of the Invention

[0005] 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.

[0006] This disclosure provides a driving assembly for an air guide plate and an indoor air conditioning unit to solve the problem of complex driving structures for large-angle rotation of the air guide plate.

[0007] In some embodiments, the driving assembly for the air guide plate includes: a gear; a motor for driving the gear; and a rack connecting plate for connecting to the air guide plate. The rack connecting plate includes a first rack and a second rack, and the gear is located between the first rack and the second rack. The gear can drive either the first rack or the second rack. Both the first rack and the second rack are arc-shaped structures. When the gear drives the first rack, the first rack rotates about the arc center of the first rack, causing the air guide plate to be in an upward opening state. When the gear drives the second rack, the second rack rotates about the arc center of the second rack, causing the air guide plate to be in a downward opening state.

[0008] Optionally, the teeth of the first rack are located on the convex surface of the arc-shaped structure of the first rack; the teeth of the second rack are located on the convex surface of the arc-shaped structure of the second rack.

[0009] Optionally, the rack connecting plate further includes an arc-shaped connecting section connecting the first rack and the second rack.

[0010] Optionally, when the air guide plate is in the closed state, the gear is located on the concave surface of the arc-shaped connecting section.

[0011] Optionally, the rack connecting plate includes a connecting portion, and the rack connecting plate is detachably connected to the air guide plate through the connecting portion.

[0012] Optionally, the first rack extends in an arc shape to one end of the rack connecting plate; the second rack extends in an arc shape to the other end of the rack connecting plate.

[0013] Optionally, a portion of the circumferential surface of the gear is provided with teeth.

[0014] Optionally, the drive assembly further includes: a first guide structure mounted on the rack connecting plate; and a second guide structure mounted on the air guide plate bracket, wherein the first guide structure and the second guide structure cooperate with each other to guide the rotation of the rack connecting plate and the air guide plate.

[0015] In some embodiments, the indoor unit of the air conditioner includes: a drive assembly for the air guide plate as described above.

[0016] Optionally, the indoor unit of the air conditioner further includes an air guide plate, and the rack and pinion connecting plate is installed on the inner side wall of the air guide plate.

[0017] 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:

[0018] This application integrates a first rack for opening the air guide plate upwards and a second rack for opening the air guide plate downwards on a rack connecting plate. The gear can drive either the first rack or the second rack. When the gear drives the first rack, the air guide plate is in the upward opening state. When the gear drives the second rack, the air guide plate is in the downward opening state. Therefore, this application can achieve both upward and downward opening states of the air guide plate with only one drive mechanism.

[0019] Furthermore, since the air guide plate is connected to the rack and pinion connecting plate, the air guide plate can be rotated at a large angle through a set of drive structures with the cooperation of the gear and rack and pinion connecting plate. At the same time, the air guide plate can be closed without creating obvious gaps that would affect the use of the air conditioner.

[0040] The upward opening state of this application refers to the state in which the air guide plate 30 is in the upward opening state, and the downward opening state refers to the state in which the air guide plate 30 is in the downward opening state.

[0041] In this application, the upward opening action refers to the action of making the air guide plate 30 open upward, and the downward opening action refers to the action of making the air guide plate 30 open downward.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0043] Combination Figure 1-5 As shown, this embodiment of the present disclosure provides a drive assembly for an air guide plate, including a gear 10, a motor 50, and a rack and pinion connecting plate 20.

[0044] The motor 50 drives the gear 10, and the rack connecting plate 20 connects to the air guide plate 30. The rack connecting plate 20 includes a first rack 214 and a second rack 215. The gear 10 is located between the first rack and the second rack. Both the first rack 214 and the second rack 215 are arc-shaped racks. The gear 10 can mesh with the first rack 214 or the second rack 215 to drive the first rack 214 or the second rack 215 to rotate. When the gear 10 drives the first rack 214, the first rack 214 rotates about the first rotation center as an axis, so that the air guide plate 30 is in an upward opening state. When the gear 10 drives the second rack 215, the second rack 215 rotates about the second rotation center as an axis, so that the air guide plate 30 is in a downward opening state.

[0045] This can be understood as follows: both the first rack 214 and the second rack 215 are arc-shaped structures. The gear 10 can mesh with either the first rack 214 or the second rack 215. When the gear 10 drives the first rack 214 to rotate, the gear 10 and the second rack 215 are not meshed; when the gear 10 drives the second rack 215 to rotate, the gear 10 and the first rack 214 are not meshed. By controlling the rotation direction and number of rotations of the gear 10, the gear 10 can only selectively drive either the first rack 214 or the second rack 215.

[0046] The first rack 214 is mainly used to keep the air guide plate 30 in an upward opening state, and the second rack 215 is mainly used to keep the air guide plate 30 in a downward opening state. The rack connecting plate 20 mainly plays a transmission role. Since the first rack 214 and the second rack 215 are mounted on the rack connecting plate 20 and the rack connecting plate 20 is connected to the air guide plate 30, when the first rack 214 or the second rack 215 moves under the drive of the gear 10, the air guide plate 30 will also move accordingly.

[0047] As an example, both the first rack 214 and the second rack 215 are arc-shaped structures. The teeth of both racks 214 and 215 are disposed on the convex surface of the arc-shaped structure, and both teeth face the gear 10. The first end of the first rack 214 is close to the first end of the second rack 215, and the second end of the first rack 214 is far from the second end of the second rack 215. In the initial state, the gear 10 is located at the first ends of both racks 214 and 215, and meshes with both racks 214 and 215. Figure 1 As shown. At this time, the air guide plate is in the closed state. When the gear 10 needs to drive the first rack 214 or the second rack 215, the gear 10 is rotated in the corresponding driving direction and disengaged from the other rack. When the air guide plate 30 needs to be closed or opened in another direction, the gear 10 is rotated in the opposite direction to the initial driving direction.

[0048] Preferably, the motor 50 is a bidirectional drive motor, capable of driving the gear 10 to rotate in both directions.

[0049] The drive assembly for the air guide plate 30 provided in this embodiment integrates a first rack 214 for opening the air guide plate 30 upwards and a second rack 215 for opening the air guide plate 30 downwards onto a rack connecting plate 20. A gear 10 can drive either the first rack 214 or the second rack 215. When the gear 10 drives the first rack 214, the air guide plate 30 is in an upward-opening state; when the gear 10 drives the second rack 215, the air guide plate 30 is in a downward-opening state. Therefore, this application can achieve both upward and downward opening states of the air guide plate 30 with only one drive mechanism, enabling large-angle rotation and simultaneous closing of the air guide plate. Optionally, the number of gears 10 is one. The drive assembly for the air guide plate provided in this embodiment has fewer moving mechanisms, reducing the probability of air guide plate movement failure and improving the reliability of the air guide plate 30's movement.

[0050] The first rack 214 and the second rack 215 have different arc centers. When the gear 10 drives the first rack 214, the first rack 214 rotates around its own arc center, i.e., the first rotation center, and drives the air guide plate body 31 to rotate, at which time the air guide plate 30 is in an upward-opening state. When the gear 10 drives the second rack 215, the second rack 215 rotates around its own arc center, i.e., the second rotation center, and drives the air guide plate body 31 to rotate, at which time the air guide plate 30 is in a downward-opening state. The first rotation center and the second rotation center can be understood as virtual axes.

[0051] like Figure 4 As shown, optionally, the first rack 214 and the second rack 215 are symmetrically arranged on the rack connecting plate 20.

[0052] This can be understood as follows: the maximum arc length of the gear 10 driving the first rack 214 to move is equal to the maximum arc length of the gear 10 driving the second rack 215 to move; and the maximum opening angle of the air guide plate 30 opening upward is the same as the maximum opening angle of the air guide plate opening downward.

[0053] Optionally, when gear 10 is located on the perpendicular bisector of the line connecting the arc centers of the first rack 214 and the second rack 215, the air guide plate 30 is in a closed state, such as... Figure 1 As shown.

[0054] This can be understood as follows: since the position of gear 10 remains unchanged, when gear 10 drives the first rack 214 or the second rack 215 to rotate, the rack connecting plate 20 will also move accordingly. The line connecting the arc centers of the first rack 214 and the second rack 215 and their perpendicular bisector will also be in motion with the movement of the rack connecting plate 20. Only when the rack connecting plate 20 returns to its initial position, that is, when gear 10 is simultaneously engaged with the first rack 214 and the second rack 215, is the air guide plate 30 in the closed state. When gear 10 is engaged with only one rack, it will be in the open state. Figure 1-3 As shown.

[0055] Optionally, a portion of the circumferential surface of the gear 10 is provided with teeth.

[0056] This can be understood as follows: the working surface of gear 10 includes two parts: a toothed part and a toothless part.

[0057] As an example, the arc length of the toothed portion is related to the arc length of the first rack 214 and the second rack 215. The arc length of the toothed portion is less than or equal to the arc length of the first rack and the second rack. Optionally, the toothed portion of the gear 10 is provided with continuous teeth. Optionally, the area of ​​the toothless portion is greater than the area of ​​the toothed portion.

[0058] As an example, the toothed portion and the toothless portion are located on opposite sides of the working surface of the gear 10. In the initial state, the toothless portion of the gear 10 faces the gap between the first rack 214 and the second rack 215, as shown below. Figure 1 As shown, when gear 10 starts to drive the first rack 214, the toothed part meshes with the first rack 214, and the toothless part faces the second rack 215. Gear 10 does not mesh with the first rack 214 and the second rack 215 at the same time to avoid jamming.

[0059] Optionally, the first rack 214 extends in an arc shape towards one end of the rack connecting plate 20; the second rack 215 extends in an arc shape towards the other end of the rack connecting plate 20, such as... Figure 4 As shown.

[0060] This can be understood as follows: the first ends of the first rack 214 and the second rack 215 are both located in the lower middle part of the rack connecting plate 20. The first rack 214 extends in an arc towards one end of the rack connecting plate 20, and the second rack 215 extends in an arc towards the other end of the rack connecting plate 20. The center of the arc of the first rack 214 is located below one side of the rack connecting plate 20, and the center of the arc of the second rack 215 is located below the other side of the rack connecting plate 20. The rack connecting plate 20 can rotate around the centers of the arcs of the first rack 214 and the second rack 215, respectively. Since the centers of the arcs of the first rack 214 and the second rack 215 are both located on the side of the rack connecting plate 20, compared to a structure where the center of rotation is located in the middle, the rack connecting plate 20 and the air guide plate 30 connected to it can rotate at a large angle to achieve large-area air delivery.

[0061] Optionally, the rack connecting plate 20 includes a rack portion 21, which has an outwardly opening U-shaped structure. The U-shaped structure includes a bottom 213 and a first side portion 211 and a second side portion 212 extending outward along the bottom 213. A first rack 214 is disposed on the first side portion 211, and a second rack 215 is disposed on the second side portion 212. The first rack 214 and the second rack 215 are connected by an arc-shaped connecting section located at the bottom 213. The arc-shaped connecting section can be integrally formed with the bottom 213.

[0062] Optionally, the rack connecting plate 20 includes a connecting part 22; the rack connecting plate 20 is detachably connected to the air guide plate 30 through the connecting part 22, thereby facilitating the disassembly and assembly of the air guide plate 30.

[0063] The rack and pinion connecting plate 20 can be understood as mainly comprising two parts: a rack section 21 and a connecting section 22. The rack section 21 is the main component that meshes with the gear 10, and the connecting section 22 is the main component that connects with the air guide plate 30. When the gear 10 is initially positioned, i.e., when the air guide plate 30 is in the closed state, it is located at the bottom 213 of the U-shaped structure, i.e., the concave surface of the arc-shaped connecting section. When the gear 10 drives the first rack 214, the rack and pinion connecting plate 20 rotates around the arc center of the first rack 214, causing the air guide plate body 31 to rotate, and the air guide plate 30 is in an upward-opening state. When the gear 10 drives the second rack 215, the rack and pinion connecting plate 20 rotates around the arc center of the second rack 215, causing the air guide plate body 31 to rotate, and the air guide plate 30 is in a downward-opening state.

[0064] As an example, the entire circumferential surface of the gear 10 is provided with teeth, while the bottom 213 of the rack connecting plate 20 is not provided with teeth, to avoid the gear 10 and the rack part 21 getting stuck and affecting normal rotational engagement.

[0065] As another example, the bottom 213 of the U-shaped structure is not toothed. Part of the circumferential surface of the gear 10 is toothed. The working surface of the gear 10 includes a toothed portion and a toothless portion, located on opposite sides of the working surface. In the initial state, the toothless portion of the gear 10 faces the bottom 213. When the gear 10 begins to drive the first rack 214, the toothed portion meshes with the first rack 214, and the toothless portion faces the second rack 215; the gear 10 does not mesh with the second rack 215. When the gear 10 begins to drive the second rack 215, the toothed portion meshes with the second rack 215, and the toothless portion faces the first rack 214; the gear 10 does not mesh with the first rack 214. The gear 10 does not mesh with both the first rack 214 and the second rack 215 simultaneously, preventing the rack connecting plate 20 from jamming.

[0066] As another example, the bottom 213 of the U-shaped structure is provided with teeth for buffering the rack engagement switching process. The working surface of the gear 10 includes a toothed part and a toothless part, which are located on both sides of the working surface of the gear 10. In the initial state, the toothless part of the gear 10 faces the bottom 213. When the gear 10 starts to drive the first rack 214, the toothed part meshes with the first rack 214, the toothless part faces the second rack 215, the gear 10 does not mesh with the second rack 215, and the air guide plate 30 is in an upward opening state. When the gear 10 starts to drive the second rack 215, the toothed part meshes with the second rack 215, the toothless part faces the first rack 214, the gear 10 does not mesh with the first rack 214, and the air guide plate 30 is in a downward opening state.

[0067] The gear 10 does not mesh with the first rack 214 and the second rack 215 at the same time, so as to avoid the rack connecting plate 20 from getting stuck.

[0068] Combination Figure 5 , Figure 6 As shown, optionally, the drive assembly also includes a first guide structure 2211 and a second guide structure 41.

[0069] The first guide structure 2211 is installed on the rack connecting plate 20, and the second guide structure 41 is installed on the air guide plate bracket 40. The first guide structure 2211 and the second guide structure 41 cooperate with each other to guide the rotation of the rack connecting plate 20 and the air guide plate 30.

[0070] This can be understood as follows: when gear 10 drives the first rack 214 or the second rack 215 to rotate, the rack connecting plate 20 and the air guide plate 30 will also rotate accordingly. In order to prevent the movement trajectory of the rack connecting plate 20 and the air guide plate 30 from deviating and affecting the normal use of the air conditioner, a mutually cooperating guide structure is set on the rack connecting plate 20 and the air guide plate bracket 40 to guide the rotation of the rack connecting plate 20 and the air guide plate 30, and to install the rack connecting plate 20 and the air guide plate 30 on the indoor unit of the air conditioner.

[0071] As an example, the rack and pinion connecting plate 20 and the air guide plate bracket 40 are in sliding or rolling engagement. The first guide structure 2211 is a slider or ball bearing, and the second guide structure 41 is a slide rail. Alternatively, the first guide structure 2211 can be a slide rail, and the second guide structure 41 can be a slider or ball bearing.

[0072] As another example, the connecting part 22 of the rack connecting plate 20 includes a connecting plate body 221 and a connector 222. A first guide structure 2211 is provided on one side of the connecting plate body 221, and a rack part 21 is installed on the other side of the connecting plate body 221. The rack part 21 is a hollow structure, and the connector 222 is installed inside the hollow structure. An opening is provided on the side of the rack part 21 near the bottom 213, through which the air guide plate 30 can pass and connect with the connector 222. The rack connecting plate 20 installs the air guide plate 30 on the air guide plate bracket 40 through the cooperation of the first guide structure 2211 and the second guide structure 41.

[0073] This disclosure provides an air conditioner indoor unit including the aforementioned drive assembly for the air guide plate 30.

[0074] Combination Figure 7 As shown, optionally, the indoor unit of the air conditioner also includes an air guide plate 30, and a rack and pinion connecting plate 20 is installed on the inner side wall of the air guide plate 30 and located on the windward side of the air guide plate 30.

[0075] As an example, two rack connecting plates 20 are provided, and the two rack connecting plates 20 are respectively located on the inner sidewalls at both ends of the air guide plate 30.

[0076] Combination Figure 8 , Figure 9 As shown, optionally, the indoor unit of the air conditioner also includes a gear box 60. The gear box 60 is provided with a motor receiving cavity 61 and a connecting plate mounting area 62. The gear box 60 has an open structure, including a mounting opening 63 and a rotating opening 64. The mounting opening 63 is used for the rack connecting plate 20 to cooperate with the air guide plate bracket 40, and the rotating opening 64 is used for the rack connecting plate 20 to drive the air guide plate 30 to rotate.

[0077] This can be understood as follows: during installation, the mounting opening 63 of the gear box 60 faces the air guide plate bracket 40. The gear box 60 is fixed to the air guide plate bracket 40 by a connector. The motor 50 is installed in the motor receiving cavity 61 and is connected to the gear 10. The gear 10 meshes with the first rack 214 or the second rack 215 on the rack connecting plate 20. The rack connecting plate 20 is rotatably installed in the connecting plate mounting area 62. The rack connecting plate 20 is installed on the air guide plate bracket 40 through the first guide structure 2211 to ensure a stable connection between the gear 10 and the rack connecting plate 20.

[0078] This application provides a drive assembly and an indoor air conditioning unit capable of being driven by a single drive unit to rotate the air guide plate 30 at a large angle.

[0079] The motion principle of the drive component is explained below.

[0080] The teeth of the first rack 214 and the second rack 215 are both disposed on the convex surface of the arc-shaped structure. The first ends of the first rack 214 and the second rack 215 are both located in the lower middle part of the rack connecting plate 20. The first rack 214 extends arc-shaped towards one end of the rack connecting plate 20, and the second rack 215 extends arc-shaped towards the other end of the rack connecting plate 20. That is, the first end of the first rack 214 is close to the first end of the second rack 215, and the second end of the first rack 214 is far from the second end of the second rack 215. The arc center of the first rack 214 is located below one side of the rack connecting plate 20, and the arc center of the second rack 215 is located below the other side of the rack connecting plate 20. The rack connecting plate 20 can rotate about the arc centers of the first rack 214 and the second rack 215 respectively. The gear 10 is initially located at the first ends of the first rack 214 and the second rack 215.

[0081] Taking gear 10 as an example (with all teeth), during implementation, gear 10 initially meshes with both the first rack 214 and the second rack 215. When the air guide plate 30 needs to be in an upward opening state, gear 10 rotates in the first direction from its initial state. During this process, gear 10 disengages from the second rack 215 and begins to drive the first rack 214. At this time, the first rack 214 rotates around the first rotation center, causing the air guide plate 30 to open upward. By controlling the rotation angle of gear 10 or the displacement of gear 10 on the first rack 214, the size of the upward opening of the air guide plate 30 can be adjusted. When it is necessary to close the air guide plate 30, gear 10 rotates in the second direction, driving the rack connecting plate 20 back to its initial position via the first rack 214. Wheel 10 engages with the first ends of the first rack 214 and the second rack 215 simultaneously. When it is necessary to switch the air guide plate 30 from the upward opening state to the downward opening state, firstly, the gear 10 is rotated in the second direction to return the rack connecting plate 20 to the initial position. Then, it continues to rotate in the second direction to disengage the gear 10 from the first rack 214 and start driving the second rack 215. The second rack 215 rotates around the second rotation center as an axis, driving the air guide plate 30 to open downward. By controlling the rotation angle of the gear 10 or the displacement of the gear 10 on the second rack 215, the size of the downward opening of the air guide plate 30 can be adjusted.

[0082] Similarly, when the air guide plate 30 needs to be in a downward opening state, the gear 10 starts from its initial state and rotates in the second direction. During this process, the gear 10 disengages from the first rack 214 and begins to drive the second rack 215. At this time, the second rack 215 rotates around the second rotation center, causing the air guide plate 30 to open downward. By controlling the rotation angle of the gear 10 or the displacement of the gear 10 on the second rack 215, the size of the downward opening of the air guide plate 30 can be adjusted. When it is necessary to close the air guide plate 30, the gear 10 rotates in the first direction, and the second rack 215 drives the rack connecting plate 20 back to its initial position. When gear 10 meshes with the first ends of the first rack 214 and the second rack 215 again, when it is necessary to switch the air guide plate 30 from the downward opening state to the upward opening state, firstly, gear 10 is rotated in the first direction to return the rack connecting plate 20 to the initial position, and then it continues to rotate in the first direction to disengage gear 10 from the second rack 215 and start driving the first rack 214. The first rack 214 rotates around the first rotation center as the axis, driving the air guide plate 30 to open upward. By controlling the rotation angle of gear 10 or the displacement of gear 10 on the first rack 214, the size of the upward opening of the air guide plate 30 can be adjusted.

[0083] This application integrates a first rack 214 for opening the air guide plate 30 upwards and a second rack 215 for opening the air guide plate 30 downwards onto a rack connecting plate 20. A gear 10 can drive either the first rack 214 or the second rack 215. When the gear 10 drives the first rack 214, the air guide plate 30 is in an upward-opening state; when the gear 10 drives the second rack 215, the air guide plate 30 is in a downward-opening state. Therefore, this application can achieve both upward and downward opening states for the air guide plate 30 using only one drive mechanism, while also enabling the air guide plate 30 to be closed. The drive assembly for the air guide plate and the air conditioner indoor unit provided in this disclosure have fewer moving mechanisms for driving the air guide plate, reducing the probability of air guide plate movement failure and improving the reliability of the air guide plate 30 movement.

[0084] Furthermore, since the air guide plate 30 is connected to the rack and pinion connecting plate 20, the air guide plate 30 can achieve large-angle rotation through a set of drive mechanisms with the cooperation of the gear 10 and the rack and pinion connecting plate 20, without producing obvious gaps that would affect the use of the air conditioner.
