[0035] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0036] like Figures 1 to 3 As shown, the air deflector driving device of the disclosed embodiment includes a mounting frame 1, a driving member 2, a rocker arm 3, and a limiting member 4. The driving member 2 is connected to the mounting frame 1, and the driving member 2 is in transmission connection with the rocker arm 3 to drive the rocker arm 3 to rotate relative to the mounting frame 1. The limiting member 4 is connected to the mounting frame 1, and the rocker arm 3 is connected to the limiting member 4.

[0037] When in use, the swing rod 3 is connected to the wind deflector, for example, Figure 2 and Figure 4 As shown, the rocker arm 3 has a connecting portion 33, which is transmission-connected to the air guide plate.

[0038] The air deflector drive device of the disclosed embodiment uses a driver 2 to rotate a rocker 3, which in turn drives the air deflector to different air supply angles. By connecting the rocker 3 to a stopper 4, the stopper 4 limits the position of the rocker 3 during rotation, reducing the risk of rocker 3 shaking. This improves the rotational accuracy of the air deflector and reduces the risk of unusual noise from the rocker 3.

[0039] In some embodiments, as Figures 2 to 4 As shown, the rocker arm 3 is provided with a protrusion 322 on one axial side of its rotation axis, and the limiting member 4 is provided on the side of the rocker arm 3 facing the protrusion 322 , and the protrusion 322 is rotatably connected to the limiting member 4 .

[0040] By rotatably connecting the protrusion 322 of the rocker arm 3 with the limit member 4, the limit member 4 can be used to limit the axial position of the rocker arm 3 on the rotating shaft when the rocker arm 3 rotates, thereby reducing the risk of the rocker arm 3 shaking, thereby improving the rotation accuracy of the air guide plate and reducing the risk of abnormal noise generated by the rocker arm 3.

[0041] Alternatively, as Figure 3 As shown, the protrusion 322 is an insertion shaft, the limiting member 4 is provided with a socket 411, and the insertion shaft is rotatably connected to the socket 411.

[0042] By setting the protrusion 322 as an insertion shaft, providing the limiting member 4 with a socket 411, and utilizing the insertion shaft and the socket 411 to be rotatably connected, the protrusion 322 and the limiting member 4 are conveniently rotatably connected, thereby facilitating the assembly of the air guide plate drive device.

[0043] Optionally, the insertion shaft and the insertion hole 411 are clearance-fitted.

[0044] The clearance fit between the plug shaft and the socket 411 can improve the connection accuracy between the rocker arm 3 and the limiter 4, further reduce the risk of the rocker arm 3 shaking, further improve the rotation accuracy of the air guide plate and reduce the risk of abnormal noise generated by the rocker arm 3.

[0045] In order to make the technical solution of the present disclosure easier to understand, the following takes the axial direction of the rotating shaft and the left-right direction as an example to further describe the technical solution of the present disclosure, wherein the left-right direction is as follows: Figures 1 to 7 shown.

[0046] For example, Figures 1 to 3 As shown, a protrusion 322 is provided on the right side of the swing rod 3, the limiting member 4 is provided on the right side of the swing rod 3, the insertion hole 411 extends in the left-right direction, and the protrusion 322 is inserted into the insertion hole 411 from left to right.

[0047] Alternatively, as Figure 3As shown, the limiting member 4 includes a guide hole 412, which is arranged on a side of the insertion hole 411 facing the rocker 3 and is connected to the insertion hole 411. The diameter of the guide hole 412 gradually increases in a direction away from the insertion hole 411.

[0048] For example, Figure 3 As shown, the rocker arm 3 is arranged on the left side of the limiting member 4, the guide hole 412 is arranged on the left side of the insertion hole 411, and the diameter of the guide hole 412 gradually decreases from right to left.

[0049] By providing the guide hole 412 , the guide hole 412 can guide the protrusion 322 during the insertion of the protrusion 322 into the guide hole 412 , making it easier for the protrusion 322 to be inserted into the guide hole 412 , thereby facilitating the assembly of the air guide plate drive device.

[0050] Alternatively, as Figure 3 As shown, the rocker 3 includes an extension section 311, which is arranged on the side of the protrusion 322 away from the stopper 4. At least a portion of the extension section 311 is arranged in the guide hole 412, and the diameter of the extension section 311 gradually increases in the direction away from the insertion hole 411.

[0051] For example, the extension section 311 is disposed on the left side of the protrusion 322 , and the diameter of the extension section 311 gradually increases from right to left. A portion of the extension section 311 is disposed in the guide hole 412 , and another portion of the extension section 311 is disposed outside the guide hole 412 .

[0052] By providing an extension section 311 on the rocker arm 3, and gradually increasing the diameter of the extension section 311 in the direction away from the socket 411, the stiffness of the rocker arm 3 can be improved, further reducing the risk of the rocker arm 3 shaking, improving the rotation accuracy of the air guide plate, and reducing the risk of abnormal noise generated by the rocker arm 3.

[0053] In some embodiments, the minimum dimension of the rocker 3 in the axial direction of its rotation axis is 12 mm to 24 mm.

[0054] For example, Figure 5 As shown, the minimum dimension of the rocker 3 in the axial direction of its rotation axis is L, which is 19.5 mm.

[0055] By setting the minimum dimension of the rocker arm 3 in the axial direction of its rotating shaft to 12 mm to 24 mm, the thickness of the rocker arm 3 is made larger, which can improve the rigidity of the rocker arm 3, further reduce the risk of the rocker arm 3 shaking, improve the rotation accuracy of the air guide plate, and reduce the risk of the rocker arm 3 generating abnormal noise.

[0056] In some embodiments, as Figure 3 and Figure 6As shown, the rocker arm 3 includes a rod body 31 and a limiting rod 32. The rod body 31 is in driving connection with the driving member 2. The limiting rod 32 includes a first section 321 and a second section. The second section and the first section 321 are arranged along the axial direction of the rotating shaft. The first section 321 is fixedly connected to the rod body 31, and the second section forms a protrusion 322.

[0057] For example, the rod body 31 is arranged on the left side of the limiting rod 32, the first section 321 is arranged on the left side of the second section, the first section 321 is embedded in the rod body 31, and the second section is located outside the rod body 31, and the second section forms a protrusion 322.

[0058] By setting the pendulum rod 3 to the above structure, it is convenient to design and manufacture different parts of the pendulum rod 3 according to the requirements of different parts of the pendulum rod 3, so that the stiffness of the pendulum rod 3 meets the requirements while the cost of the pendulum rod 3 is low.

[0059] Alternatively, as Figure 3 and Figure 6 As shown, the diameter of the first section 321 is greater than the diameter of the second section.

[0060] By setting the diameter of the first section 321 to be larger than the diameter of the second section, not only can the connection area between the limit rod 32 and the rod body 31 be increased, thereby improving the connection reliability between the limit rod 32 and the rod body 31; but also the limit rod 32 can be prevented from falling off from the limit member 4 in a direction away from the rod body 31, thereby improving the reliability of the air guide plate driving device.

[0061] Optionally, the limiting rod 32 is a metal rod.

[0062] By setting the limit rod 32 as a metal rod, the friction coefficient between the limit rod 32 and the limit member 4 can be reduced, avoiding abnormal noise generated by friction between the rocker arm 3 and the limit member 4 during rotation, and further reducing the risk of abnormal noise generated during rotation of the rocker arm 3.

[0063] Optionally, the rod body 31 is made of plastic, and the rod body 31 and the limiting rod 32 are integrally injection molded.

[0064] In some embodiments, the limiting member 4 is detachably connected to the mounting bracket 1 .

[0065] For example, Figure 7 As shown, the limiting member 4 is provided with a fixing hole 421, and the fastener passes through the fixing hole 421 and is connected to the mounting frame 1. The fastener can be a bolt, a screw, etc.

[0066] By detachably connecting the limiting member 4 to the mounting bracket 1 , the limiting member 4 can be easily replaced and repaired.

[0067] Alternatively, as Figure 7As shown, the limiting member 4 includes a limiting body 41 and fixing ears 42. The fixing ears 42 are arranged on opposite sides of the limiting body 41 in the radial direction of the rotation axis and are connected to the limiting body 41. The protrusion 322 is rotatably connected to the limiting body 41, and the fixing ears 42 are connected to the mounting bracket 1.

[0068] For example, Figure 7 As shown, the insertion hole 411 is provided on the limiting body 41 , and the fixing ears 42 are provided on the upper and lower sides of the limiting body 41 .

[0069] By configuring the limiting member 4 to include a limiting body 41 and a fixing ear 42 , different parts of the limiting member 4 are respectively connected to the protrusion 322 and the mounting frame 1 , further facilitating the installation and fixation of the limiting member 4 and the assembly of the air guide plate drive device.

[0070] Optionally, the limiting body 41 and the fixing ear 42 are integrally formed.

[0071] For example, the limiting body 41 and the fixing ear 42 are integrally injection molded.

[0072] Alternatively, as Figures 1 to 3 As shown, the air deflector drive device further includes a reduction gearbox 5, which includes a housing 51 and an output shaft 52. The housing 51 is connected to the mounting frame 1, and the driving member 2 is connected to the rocker 3 via the output shaft 52. The driving member 2 can be a motor, and a plurality of gears are provided in the housing 51.

[0073] By providing the reduction box 5 , the output torque of the driving member 2 can be increased, the output torque of the rocker arm 3 can be increased, and the rotation stability of the air guide frame can be improved.

[0074] Alternatively, as Figures 1 to 3 As shown, the reduction box 5 and the limiting member 4 are arranged on opposite sides of the rocker 3 in the axial direction of the rotating shaft.

[0075] For example, the reduction gear box 5 is arranged on the left side of the rocker arm 3, and the limiter 4 is arranged on the right side of the rocker arm 3. The reduction gear box 5 and the limiter 4 can be used to achieve stable limitation of the rocker arm 3 in the left and right directions, further reducing the risk of shaking of the rocker arm 3, further improving the rotation accuracy of the air guide plate and reducing the risk of abnormal noise generated by the rocker arm 3.

[0076] Optionally, the rigidity of the rocker arm 3 can be increased by increasing the size of the rocker arm 3 in the axial direction of the rotating shaft, thereby reducing the risk of the rocker arm 3 shaking, further improving the rotation accuracy of the air guide plate, and reducing the risk of the rocker arm 3 generating abnormal noise.

[0077] The air conditioner indoor unit of the embodiment of the present disclosure includes an air deflector and an air deflector driving device, the air deflector driving device being the air deflector driving device of any of the above embodiments, and the swing arm 3 being connected to the air deflector.

[0078] The air conditioner indoor unit of the embodiment of the present disclosure can reduce the risk of the swing arm 3 shaking, improve the rotation accuracy of the air guide plate, and reduce the risk of the swing arm 3 generating abnormal noise.

[0079] Alternatively, as Figure 1 As shown, the air conditioner indoor unit includes a middle frame, which forms a mounting frame 1.

[0080] By using the middle frame as the mounting bracket 1 , the air guide plate driving device can be integrated and mounted on the middle frame, thereby improving the integration of the air conditioner indoor unit.

[0081] The air deflector drive device and air conditioner indoor unit of the disclosed embodiments can reduce the risk of shaking of the swing arm 3, improve the rotational accuracy of the air deflector, and reduce the risk of abnormal noise generated by the swing arm 3. Furthermore, the rigidity of the swing arm 3 is enhanced, preventing deformation of the swing arm 3 that could cause a closed gap in the air deflector or a discrepancy between the actual rotation angle and the ideal rotation angle.

[0082] Although the embodiments of the present disclosure have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present disclosure.
