[0035] In this embodiment of the disclosure, the first outer edge refers to the upper edge of the air guide plate body when the air guide plate body is in the closed state; the second outer 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 1-3As shown, this embodiment of the present disclosure provides an air guide plate assembly, including an air guide plate body 30, a rack and pinion connecting plate 20, and a gear 10.

[0038] The air guide plate body 30 includes a first outer edge and a second outer edge. The first outer edge flips outward when the air guide plate body 30 opens upward, and the second outer edge flips outward when the air guide plate body 30 opens downward.

[0039] like Figure 4 , Figure 5 As shown, the rack connecting plate 20 is connected to the inner side of the air guide plate body 30. The rack connecting plate 20 includes a first arc-shaped rack 211 and a second arc-shaped rack 212. The first arc-shaped rack 211 is used to open the air guide plate body 30 upward, and the second arc-shaped rack 212 is used to open the air guide plate body 30 downward.

[0040] Gear 10 can drive either the first arc-shaped rack 211 or the second arc-shaped rack 212.

[0041] When the air guide plate body 30 opens upward, the first motion arc length of the gear 10 on the first arc rack 211 is proportional to the first rotation arc length of the first outer edge; when the air guide plate body 30 opens downward, the second motion arc length of the gear 10 on the second arc rack 212 is proportional to the second rotation arc length of the second outer edge.

[0042] The air guide plate assembly provided in this embodiment is connected to the air guide plate body 30 via a rack connecting plate 20 having a first arc-shaped rack 211 and a second arc-shaped rack 212. The air guide plate can open upwards and downwards via the rack connecting plate 20. This embodiment uses a single gear drive device to achieve both upward and downward opening states, enabling large-angle rotation of the air guide plate body 30.

[0043] Furthermore, since the first motion arc length of the gear 10 on the first arc rack 211 is proportional to the first rotation arc length of the first outer edge, and the second motion arc length of the gear 10 on the second arc rack 212 is proportional to the second rotation arc length of the second outer edge, the rotation angle of the air guide plate body 30 can be controlled by controlling the first and second motion arc lengths of the gear 10 during use.

[0044] Optionally, the parameters of the first motion arc length formed by the gear 10 on the first arc-shaped rack 211 include the direction, length, and position of the first motion arc length on the first arc-shaped rack 211; the parameters of the second motion arc length formed by the gear 10 on the second arc-shaped rack 212 include the direction, length, and position of the second motion arc length on the second arc-shaped rack 212. The direction of the first motion arc length can be understood as the direction formed by the two positions of the gear 10 when it meshes with the first arc-shaped rack 211 from its initial position to its stop position; the direction of the second motion arc length can be understood as the direction formed by the two positions of the gear 10 when it meshes with the second arc-shaped rack 212 from its initial position to its stop position. It is understood that the initial position is not limited to the end position of the first arc-shaped rack 211 or the second arc-shaped rack 212, and the stop position is not limited to the end position of the first arc-shaped rack 211 or the second arc-shaped rack 212.

[0045] The air guide plate assembly provided in this embodiment improves the accuracy of controlling the opening angle of the air guide plate body 30 by limiting the first and second motion arc lengths formed by the movement of the gear 10.

[0046] Optionally, such as Figure 4 As shown, the center of the arc of the first arc-shaped rack 211 is located on one side of the rack connecting plate 20, and the center of the arc of the second arc-shaped rack 212 is located on the other side of the rack connecting plate 20.

[0047] 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 located on both sides of the rack connecting plate 20 respectively, 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.

[0048] 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 away 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.

[0049] 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.

[0050] Optionally, when gear 10 is located on the perpendicular bisector of the line connecting the centers of the first arc-shaped rack 211 and the second arc-shaped rack 212, the air guide plate is in a closed state, such as... Figure 1 As shown.

[0051] This can be understood as follows: Since the position of gear 10 remains unchanged, when gear 10 drives the first arc-shaped rack 211 or the second arc-shaped rack 212 to rotate, the rack connecting plate 20 will also move accordingly. The line connecting the arc centers of the first arc-shaped rack 211 and the second arc-shaped rack 212, 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 simultaneously meshes with the first arc-shaped rack 211 and the second arc-shaped rack 212, is the air guide plate in the closed state. When gear 10 meshes with only one rack, it will be in the open state. Figures 1 to 3 As shown.

[0052] Optionally, the air guide plate assembly also includes a control unit for controlling the meshing relationship between the gear 10 and the first arc-shaped rack 211 or the second arc-shaped rack 212, so that the air guide plate body 30 moves to a preset angle.

[0053] This can be understood as follows: the control unit controls the rotation direction and number of rotations of the output shaft of the motor connected to the gear 10, thereby controlling the rotation direction and rotation angle of the gear 10, so that the gear 10 meshes with the first arc rack 211 or the second arc rack 212. By controlling the rotation angle of the gear 10, the first and second motion arc lengths of the gear 10 can be controlled, thereby achieving the purpose of moving the air guide plate body 30 to a preset angle.

[0054] 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. The gear 10 engages again 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 an upward opening state to a downward opening state, the gear 10 is first rotated in the second direction to return the rack connecting plate 20 to its initial position. Then, it continues to rotate in the second direction to disengage the gear 10 from the first arc-shaped rack 211 and begin driving the second arc-shaped rack 212. The second arc-shaped rack 212 rotates around the second rotation center, driving the air guide plate to open downwards. The size of the downward opening of the air guide plate can be adjusted by controlling the rotation angle of the gear 10 or the arc length of the second motion trajectory. The first rotation center is the virtual rotation axis of the first arc-shaped rack 211, and the second rotation center is the virtual rotation axis of the second arc-shaped rack 212. Optionally, the first and second rotation centers do not overlap. The first and second rotation centers can be virtual rotation axes. Preferably, the first rotation center is the arc center of the first arc-shaped rack, and the second rotation center is the arc center of the second arc-shaped rack.

[0055] Optionally, the meshing relationship includes meshing position and meshing length.

[0056] This can be understood as the control unit controlling the gear 10 to mesh with the first arc-shaped rack 211 or the second arc-shaped rack 212, and controlling the meshing position of the gear 10 on the first arc-shaped rack 211, the first arc length of the gear 10 on the first arc-shaped rack 211, the meshing position of the gear 10 on the second arc-shaped rack 212, and the second arc length of the gear 10 on the second arc-shaped rack 212, thereby achieving the purpose of moving the air guide plate body 30 to a preset angle.

[0057] Optionally, when the air guide plate body 30 opens upward, the first rotation arc length and the first motion arc length satisfy L1 / D1=l1 / d1; where L1 is the first rotation arc length; l1 is the first motion arc length; D1 is the radius of the first circle where the rotation trajectory of the first outer edge is located when the air guide plate body 30 opens upward; and d1 is the radius of the second circle where the first arc-shaped rack 211 is located.

[0058] This can be understood as follows: when the gear 10 drives the first arc-shaped rack 211, the first arc-shaped rack 211 rotates synchronously with the first outer edge, and 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.

[0059] Optionally, the first circle and the second circle are concentric circles.

[0060] This can be understood as follows: when gear 10 drives the first arc-shaped rack 211, the circle containing the first rotation trajectory of the first outer edge and the circle containing the first arc-shaped rack 211 are concentric circles.

[0061] Optionally, when the air guide plate body 30 opens downwards, the second rotation arc length and the second motion arc length satisfy L2 / D2=l2 / d2; where L2 is the second rotation arc length; l2 is the second motion arc length; D2 is the radius of the third circle where the rotation trajectory of the second outer edge is located when the air guide plate body 30 opens downwards; and d2 is the radius of the fourth circle where the second arc-shaped rack 212 is located.

[0062] This can be understood as follows: when gear 10 drives the second arc-shaped rack 212, the second arc-shaped rack 212 rotates synchronously with the second outer edge, and the rotation angle of the second arc-shaped rack 212 is the same as the rotation angle of the upper edge of the air guide plate.

[0063] Optionally, the third and fourth circles are concentric.

[0064] This can be understood as follows: 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.

[0065] Optionally, the rack connecting plate 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 30, and the second rack connecting plate being disposed at the second end of the inner sidewall of the air guide plate body 30.

[0066] Optionally, a portion of the circumferential surface of the gear 10 is provided with teeth.

[0067] This can be understood as follows: the working surface of gear 10 includes two parts: a toothed part and a toothless part.

[0068] As an example, the arc length of the toothed portion is related to the arc length of the first arc rack 211 and the second arc rack 212. 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.

[0069] 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 arc-shaped rack 211 and the second arc-shaped rack 212, as shown below. Figure 2 As shown, when gear 10 starts to drive the first arc-shaped rack 211, the toothed part meshes with the first arc-shaped rack 211, and the toothless part faces the second arc-shaped rack 212. Gear 10 does not mesh with the first arc-shaped rack 211 and the second arc-shaped rack 212 at the same time to avoid jamming.

[0070] As an example, the rack and pinion connecting plate 20 is detachably mounted on the air guide plate body 30.

[0071] This disclosure provides an air conditioner including the aforementioned air guide plate assembly.

[0072] In this embodiment, a rack connecting plate 20 with a first arc-shaped rack 211 and a second arc-shaped rack 212 is connected to the air guide plate body 30. The air guide plate can open upwards and downwards through the rack connecting plate 20. In this embodiment, a single gear 10 drive device can achieve both upward and downward opening states, enabling large-angle rotation of the air guide plate body 30.

[0073] Furthermore, since the first motion arc length of the gear 10 on the first arc rack 211 is proportional to the first rotation arc length of the first outer edge, and the second motion arc length of the gear 10 on the second arc rack 212 is proportional to the second rotation arc length of the second outer edge, the rotation angle of the air guide plate body 30 can be controlled by controlling the first and second motion arc lengths of the gear 10 during use.

[0074] It is understood that the air conditioner provided in the embodiments of this disclosure can be a cabinet air conditioner, a wall-mounted air conditioner, or a commercial air conditioner.
