[0006] In some embodiments, the air guide plate driving assembly includes: an air guide plate body; an active part including a gear; and a driven part including a rack connecting plate connected to the air guide plate body. The rack connecting plate is provided with a first arc-shaped rack for opening the air guide plate body upward and a second arc-shaped rack for opening the air guide plate body downward. The gear is located between the first arc-shaped rack and the second arc-shaped rack, and the gear can drive either the first arc-shaped rack or the second arc-shaped rack. When the gear drives the first arc-shaped rack, the upper edge of the air guide plate body forms a first rotation trajectory, and the circle containing the first rotation trajectory and the circle containing the first arc-shaped rack are first concentric circles. When the gear drives the second arc-shaped rack, the lower edge of the air guide plate body forms a second rotation trajectory, and the circle containing the second rotation trajectory and the circle containing the second arc-shaped rack are second concentric circles.

[0007] Optionally, when the gear drives the first arc-shaped rack, the gear moves on the first arc-shaped rack to generate a first motion trajectory, and the first rotation trajectory and the first motion trajectory satisfy L1 / D1=l1 / d1; where L1 is the length of the first rotation trajectory, l1 is the length of the first motion trajectory, D1 is the radius of the circle where the first rotation trajectory is located, and d1 is the radius of the circle where the first motion trajectory is located.

[0008] Optionally, when the gear drives the second arc-shaped rack, the gear moves on the second arc-shaped rack to generate a second motion trajectory, and the second rotation trajectory and the second motion trajectory satisfy L2 / D2=l2 / d2; where L2 is the length of the second rotation trajectory, l2 is the length of the second motion trajectory, D2 is the radius of the circle containing the second rotation trajectory, and d2 is the radius of the circle containing the second motion trajectory.

[0009] Optionally, the center O1 of the first concentric circle and the center O2 of the second concentric circle are not in the same position.

[0010] Optionally, the center O1 is located on one side of the rack connecting plate, and the center O2 is located on the other side of the rack connecting plate.

[0011] Optionally, the teeth of the first arc-shaped rack and the second arc-shaped rack are arranged facing each other; the first end of the first arc-shaped rack is close to the first end of the second arc-shaped rack, and the second end of the first arc-shaped rack is far from the second end of the second arc-shaped rack; when the air guide plate body is closed, the gear meshes with the first ends of the first arc-shaped rack and the second arc-shaped rack.

[0012] Optionally, the air guide plate drive assembly further includes: a transition arc plate, one end of which is connected to the first end of the first arc-shaped rack and the other end of which is connected to the first end of the second arc-shaped rack, wherein the concave surface of the transition arc plate is used to support the gear.

[0013] Optionally, the rack connecting plate is provided with a guide structure that cooperates with the air guide plate bracket.

[0014] Optionally, the rack connecting plate is detachably connected to the air guide plate body.

[0016] The air guide vane drive assembly and air conditioner indoor unit provided in this disclosure can achieve the following technical effects:

[0017] In this embodiment, the air guide plate body is connected to the rack connecting plate. The rack connecting plate is provided with a first arc-shaped rack and a second arc-shaped rack. When the gear drives the first arc-shaped rack to rotate, the upper edge of the air guide plate body will rotate and form a first rotation trajectory. Since the first rotation trajectory and the circle where the first arc-shaped rack is located are concentric circles, the upper edge of the air guide plate body rotates synchronously with the first arc-shaped rack. When the gear drives the second arc-shaped rack to rotate, the lower edge of the air guide plate body will rotate and form a second rotation trajectory. Since the second rotation trajectory and the circle where the second arc-shaped rack is located are concentric circles, the lower edge of the air guide plate body rotates synchronously with the second arc-shaped rack.

[0018] When the gear does not drive the first and second arc-shaped racks, the gear is located at the starting drive end of the first and second arc-shaped racks. At this time, the upper and lower edges of the air guide plate body will also be located at the starting position, which can ensure that the air guide plate can cover the air outlet when closed, thus achieving the effect of dust prevention.

[0035] In this embodiment of the disclosure, the upper edge refers to the upper edge of the air guide plate body when the air guide plate body is in the closed state; the lower edge refers to the lower edge of the air guide plate body when the air guide plate body is in the closed state.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0037] Combination Figure 1-3 As shown, this embodiment of the present disclosure provides an air guide plate driving assembly, including an air guide plate body 30, an active part, and a driven part.

[0038] The driving part includes gear 10.

[0039] The driven part includes a rack connecting plate 20 connected to the air guide plate body 30. The rack connecting plate 20 is provided with a first arc-shaped rack 211 for opening the air guide plate body 30 upward and a second arc-shaped rack 212 for opening the air guide plate body 30 downward. The gear 10 is located between the first arc-shaped rack 211 and the second arc-shaped rack 212. The gear 10 can drive the first arc-shaped rack 211 or the second arc-shaped rack 212.

[0040] When gear 10 drives the first arc-shaped rack 211, the upper edge of the air guide plate body 30 forms a first rotation trajectory, and the circle where the first rotation trajectory is located and the circle where the first arc-shaped rack 211 is located are the first concentric circles.

[0041] When gear 10 drives the second arc-shaped rack 212, the lower edge of the air guide plate body 30 forms a second rotation trajectory, and the circle where the second rotation trajectory is located and the circle where the second arc-shaped rack 212 is located are the second concentric circles.

[0042] This can be understood as follows: the first arc-shaped rack 211 and the second arc-shaped rack 212 have different arc centers. When the gear 10 drives the first arc-shaped rack 211, the first arc-shaped rack 211 rotates around its own arc center as an axis, and drives the air guide plate body 30 to rotate. At this time, the air guide plate is in an upward opening state, and the upper edge of the air guide plate body 30 rotates synchronously with the first arc-shaped rack 211. When the gear 10 drives the second arc-shaped rack 212, the second arc-shaped rack 212 rotates around its own arc center as an axis, and drives the air guide plate body 30 to rotate. At this time, the air guide plate is in a downward opening state, and the lower edge of the air guide plate body 30 rotates synchronously with the second arc-shaped rack 212.

[0043] Using the air guide plate driving assembly provided in this embodiment, the air guide plate body 30 is connected to the rack and pinion connecting plate 20. The rack and pinion connecting plate 20 is provided with a first arc-shaped rack 211 and a second arc-shaped rack 212. The gear 10 is located between the first arc-shaped rack 211 and the second arc-shaped rack 212. When the gear 10 drives the first arc-shaped rack 211 to rotate, the upper edge of the air guide plate body 30 will rotate and form a first rotation trajectory. Since the first rotation trajectory and the circle where the first arc-shaped rack 211 is located are concentric circles, the upper edge of the air guide plate body 30 rotates synchronously with the first arc-shaped rack 211. When the gear 10 drives the second arc-shaped rack 212 to rotate, the lower edge of the air guide plate body 30 will rotate and form a second rotation trajectory. Since the second rotation trajectory and the circle where the second arc-shaped rack 212 is located are concentric circles, the lower edge of the air guide plate body 30 rotates synchronously with the second arc-shaped rack 212.

[0044] When gear 10 does not drive the first arc rack 211 and the second arc rack 212, gear 10 is located at the starting drive end of the first arc rack 211 and the second arc rack 212. At this time, the upper and lower edges of the air guide plate body 30 will also be located at the starting position. At this time, the air guide plate is in the closed state, which can ensure that the air guide plate can cover the air outlet when closed, and play a dust prevention role.

[0045] In implementation, gear 10 initially meshes with both the first arc-shaped rack 211 and the second arc-shaped rack 212. When the air guide plate 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 arc-shaped rack 212 and begins to drive the first arc-shaped rack 211. At this time, the first arc-shaped rack 211 rotates around the first rotation center, causing the air guide plate to open upward. By controlling the rotation angle of gear 10 or the arc length of the first motion trajectory, the size of the upward opening of the air guide plate can be adjusted. When the air guide plate needs to be closed, gear 10 rotates in the second direction, driving the rack connecting plate 20 back to its initial position via the first arc-shaped rack 211. 0 engages with the first ends of the first arc-shaped rack 211 and the second arc-shaped rack 212 simultaneously. When it is necessary to switch the air guide plate 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 arc-shaped rack 211 and start driving the second arc-shaped rack 212. The second arc-shaped rack 212 rotates around the second rotation center as the axis, driving the air guide plate to perform the downward opening action. By controlling the rotation angle of the gear 10 or the arc length of the second motion trajectory, the size of the downward opening of the air guide plate can be adjusted.

[0046] Optionally, when the gear 10 drives the first arc-shaped rack 211, the gear 10 moves on the first arc-shaped rack 211 to generate a first motion trajectory, and the first rotation trajectory and the first motion trajectory satisfy L1 / D1=l1 / d1; where L1 is the length of the first rotation trajectory, l1 is the length of the first motion trajectory, D1 is the radius of the circle where the first rotation trajectory is located, and d1 is the radius of the circle where the first motion trajectory is located.

[0047] This can be understood as follows: the first arc-shaped rack 211 rotates synchronously with the upper edge of the air guide plate, the rotation angle of the first arc-shaped rack 211 is the same as the rotation angle of the upper edge of the air guide plate, and the rotation arc length of the upper edge of the air guide plate and the rotation arc length of the first arc-shaped rack 211 satisfy L1 / D1=l1 / d1. L1 is the rotation arc length of the upper edge of the air guide plate, and l1 is the length of the first motion trajectory, that is, the rotation length of the first arc-shaped rack 211.

[0048] Optionally, when the gear 10 drives the second arc-shaped rack 212, the gear 10 moves on the second arc-shaped rack 212 to generate a second motion trajectory. The second rotation trajectory and the second motion trajectory satisfy L2 / D2=l2 / d2; where L2 is the length of the second rotation trajectory, l2 is the length of the second motion trajectory, D2 is the radius of the circle containing the second rotation trajectory, and d2 is the radius of the circle containing the second motion trajectory.

[0049] This can be understood as follows: the second arc-shaped rack 212 rotates synchronously with the lower edge of the air guide plate, the rotation angle of the second arc-shaped rack 212 is the same as the rotation angle of the lower edge of the air guide plate, and the rotation arc length of the lower edge of the air guide plate and the rotation arc length of the second arc-shaped rack 212 satisfy L 2 / D2 = l2 / d2. L2 is the rotational arc length of the lower edge of the air guide plate, and l2 is the length of the second motion trajectory, that is, the rotational length of the second arc-shaped rack 212.

[0050] Combination Figure 1 As shown, optionally, the center O1 of the first concentric circle and the center O2 of the second concentric circle are not in the same position.

[0051] This can be understood as the center of the arc of the first arc rack 211 not coinciding with the center of the arc of the second arc rack 212.

[0052] Optionally, the center O1 is located on one side of the rack connecting plate 20, and the center O2 is located on the other side of the rack connecting plate 20.

[0053] It can be understood that the rack connecting plate 20 can rotate around the arc center of the first arc rack 211 and the arc center of the second arc rack 212 respectively. Since the arc centers of the first arc rack 211 and the second arc rack 212 are both located on the side of the rack connecting plate 20, compared with the structure where the rotation center is located in the middle, the rack connecting plate 20 and the air guide plate body 30 connected to it can rotate at a large angle to achieve large-area air delivery.

[0054] Combination Figure 4 As shown, optionally, the teeth of the first arc-shaped rack 211 and the second arc-shaped rack 212 are arranged facing each other; the first end of the first arc-shaped rack 211 is close to the first end of the second arc-shaped rack 212, and the second end of the first arc-shaped rack 211 is far from the second end of the second arc-shaped rack 212; when the air guide plate body 30 is closed, the gear 10 meshes with the first ends of the first arc-shaped rack 211 and the second arc-shaped rack 212.

[0055] As an example, both the first arc-shaped rack 211 and the second arc-shaped rack 212 are arc-shaped structures. The teeth of both racks are disposed on the convex surface of the arc-shaped structure. The teeth of both racks face the gear 10. The first end of the first arc-shaped rack 211 is close to the first end of the second arc-shaped rack 212, while the second end of the first arc-shaped rack 211 is far from the second end of the second arc-shaped rack 212. In the initial state, the gear 10 is located at the first ends of both the first arc-shaped rack 211 and the second arc-shaped rack 212, and meshes with both racks simultaneously. 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 arc rack 211 or the second arc rack 212, the gear 10 is rotated in the corresponding driving direction and disengaged from the other arc rack. When the air guide plate needs to be closed or the air guide plate needs to be opened in another direction, the gear 10 is rotated in the opposite direction to the initial driving direction.

[0056] Optionally, the air guide plate drive assembly further includes: a transition arc plate 213, one end of which is connected to the first end of the first arc-shaped rack 211, and the other end of which is connected to the first end of the second arc-shaped rack 212, wherein the concave surface of the transition arc plate 213 is used to support the gear 10.

[0057] As an example, the rack connecting plate 20 includes a rack portion 21 and a connecting portion 22. The rack portion 21 has an outwardly opening U-shaped structure, which includes a bottom and a first side portion and a second side portion extending outward from the bottom. A first arc-shaped rack 211 is disposed on the first side portion, and a second arc-shaped rack 212 is disposed on the second side portion. The first arc-shaped rack 211 and the second arc-shaped rack 212 are connected by a transition arc plate 213, which is located at the bottom and can be integrally formed with the bottom. The rack portion 21 serves as the main component that meshes with the gear 10, and the connecting portion 22 serves as the main component that connects with the air guide plate. When the gear 10 is initially positioned, i.e. when the air guide plate is closed, it is located on the concave surface of the transition arc plate 213. When the gear 10 drives the first arc rack 211, the rack connecting plate 20 rotates around the arc center of the first arc rack 211 and drives the air guide plate body 30 to rotate, and the air guide plate is in an upward opening state. When the gear 10 drives the second arc rack 212, the rack connecting plate 20 rotates around the arc center of the second arc rack 212 and drives the air guide plate body 30 to rotate, and the air guide plate is in a downward opening state.

[0058] Combination Figure 5 As shown, optionally, the rack connecting plate 20 is provided with a guide structure that cooperates with the air guide plate bracket 40.

[0059] As an example, the rack connecting plate 20 is provided with a first guide structure 221, and the air guide plate bracket 40 is provided with a second guide structure 41. The first guide structure 221 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. The rack connecting plate 20 and the air guide plate bracket 40 are in sliding or rolling engagement. The first guide structure 221 is a slider or ball bearing, and the second guide structure 41 is a slide rail. Alternatively, the first guide structure 221 can be a slide rail, and the second guide structure 41 can be a slider or ball bearing.

[0060] As another example, the connecting part 22 of the rack connecting plate 20 includes a connecting plate body 23 and a connector 222. A first guide structure 221 is provided on one side of the connecting plate body 23, and a rack part 21 is installed on the other side of the connecting plate body 23. 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, and the air guide plate can pass through the opening and connect with the connector 222. The rack connecting plate 20 installs the air guide plate on the air guide plate bracket 40 through the cooperation of the first guide structure 221 and the second guide structure 41.

[0061] Optionally, the rack connecting plate 20 is detachably connected to the air guide plate body 30. This facilitates the assembly and disassembly of the air guide plate.

[0062] This disclosure provides an indoor air conditioning unit, including the aforementioned air guide vane drive assembly.

[0063] Using the air guide plate drive assembly and air conditioner indoor unit provided in this embodiment, the air guide plate body 30 is connected to the rack and pinion connecting plate 20. The rack and pinion connecting plate 20 is provided with a first arc-shaped rack 211 and a second arc-shaped rack 212. The gear 10 is located between the first arc-shaped rack 211 and the second arc-shaped rack 212. When the gear 10 drives the first arc-shaped rack 211 to rotate, the upper edge of the air guide plate body 30 will rotate and form a first rotation trajectory. Since the first rotation trajectory and the circle where the first arc-shaped rack 211 is located are concentric circles, the upper edge of the air guide plate body 30 rotates synchronously with the first arc-shaped rack 211. When the gear 10 drives the second arc-shaped rack 212 to rotate, the lower edge of the air guide plate body 30 will rotate and form a second rotation trajectory. Since the second rotation trajectory and the circle where the second arc-shaped rack 212 is located are concentric circles, the lower edge of the air guide plate body 30 rotates synchronously with the second arc-shaped rack 212.

[0064] The air guide plate drive assembly of this application can adjust the size of the air guide plate opening by controlling the rotation angle of the gear 10, the arc length of the first motion trajectory or the second motion trajectory.

[0065] When gear 10 does not drive the first arc rack 211 and the second arc rack 212, gear 10 is located at the starting drive end of the first arc rack 211 and the second arc rack 212. At this time, the upper and lower edges of the air guide plate body 30 will also be located at the starting position, which can ensure that the air guide plate can cover the air outlet when it is closed, thus achieving the effect of dust prevention.
