As shown in fig. 7 to 10, the present embodiment provides an air deflector driving mechanism including a driving gear 70, a first gear 80 and a second gear 90.

In this embodiment, the present embodiment further provides an air conditioner, including an air conditioner indoor unit, an air conditioner outdoor unit, and a connection pipe, where one end of the connection pipe is connected with the air conditioner outdoor unit, and the other end of the connection pipe is connected with the air conditioner indoor unit, and the air conditioner indoor unit is provided with the air deflector driving mechanism.

More specifically, as shown in fig. 1, the indoor unit of the air conditioner includes a housing and a casing 60, the housing is mounted inside the casing 60, an air guide plate driving mechanism is mounted on the casing 60, and both the first air guide plate 10 and the second air guide plate 20 are connected to the air guide plate mechanism.

In this embodiment, the side of the indoor unit of the air conditioner, which is used to hang on the wall, is the rear side of the casing 60, the front side of the casing 60 is provided with an air outlet, the machine body blows air out from the air outlet, and the first air deflector 10 and the second air deflector 20 are arranged at the air outlet for adjusting the wind direction of the air outlet.

Specifically, the first air guiding plate 10 and the second air guiding plate 20 are arranged along the air outlet direction, the first air guiding plate 10 is closer to the inside of the housing 60 than the second air guiding plate 20, that is, the first air guiding plate 10 is located at the rear side of the second air guiding plate 20, the first gear 80 is connected with the first air guiding plate 10, and the second gear 90 is connected with the second air guiding plate 20.

In this embodiment, the air deflector driving mechanism further includes a driving motor and a gear set, the driving end of the driving motor is connected with the gear set, and the driving gear 70 is meshed with the gear set for transmission, so that the transmission effect is better.

More specifically, the first air guide plate 10 and the second air guide plate 20 each extend in the left-right direction, and are rotatable relative to each other about an axis extending in the left-right direction.

In this embodiment, as shown in fig. 7 to 9, the air conditioner further includes a first connection shaft 84 and a second connection shaft 92, one end of the first connection shaft 84 is connected to the first gear 80, the other end of the first connection shaft 84 is connected to the first air deflector 10, one end of the second connection shaft 92 is connected to the second gear 90, and the other end of the second connection shaft 92 is connected to the second air deflector 20.

More specifically, the second connecting shaft 92 has a through hole for the first connecting shaft 84 to pass through, and the through hole is in transition fit with the first connecting shaft 84, so that the first connecting shaft 84 does not drive the second connecting shaft 92 to rotate when rotating, and the first connecting shaft 84 and the second connecting shaft 92 can rotate relatively, so that the asynchronous rotation of the first air deflector 10 and the second air deflector 20 can be realized, and the installation space is saved.

In the practical use process, the first air deflector 10 is always in a horizontal state, when the downward air outlet function is needed, the first air deflector 10 needs to be rotated downward by 90 degrees, when the first air deflector 10 is seen from the right side, the first air deflector 10 needs to be rotated clockwise by 90 degrees, because the first air deflector 10 generally only needs to be rotated downward by 90 degrees, the first air deflector 10 is driven to rotate, and a gear missing gear is generally driven to rotate, and because errors can be generated between gear meshing, and in order to facilitate the gear missing gear to be separated from the driving gear 70, the actual meshing angle of the gear missing gear and the driving gear 70 is generally only 80 degrees, therefore, the first air deflector 10 connected with the gear missing gear often cannot accurately complete a rotation stroke of 90 degrees, and if the stroke of 90 degrees is wanted to be completed, the number of teeth of the gear missing gear is required to be set to be larger than the number of teeth corresponding to 90 degrees, but in this case, the gear missing gear and the driving gear 70 are difficult to be separated from each other to realize unsynchronized rotation.

In order to solve the above-mentioned problems, the air deflector driving mechanism of the present utility model mainly adopts the cooperation of the first transmission portion 81 and the second transmission portion 91 to ensure the travel of the first gear 80 capable of rotating 90 degrees.

In the present embodiment, as shown in fig. 7 to 10, the first gear 80 includes a first transmission portion 81, a meshing portion 82, and a tooth missing portion 83, the meshing portion 82 meshes with the driving gear 70 for transmission, the tooth missing portion 83 rotates relative to the driving gear 70, the first transmission portion 81 protrudes from the first gear 80 in the axial direction of the first gear 80, specifically, the axial direction of the first gear 80 coincides with the extending direction of the first air deflector 10, the axial direction of the first gear 80 is the left-right direction, and the first transmission portion 81 is provided on the left side of the first gear 80.

In this embodiment, as shown in fig. 7 to 10, the second gear 90 is disposed on the side surface of the first gear 80 along the axial direction of the first gear 80, specifically, the second gear 90 is disposed on the left side of the first gear 80, the second gear 90 includes a second transmission portion 91, the second transmission portion 91 protrudes toward the first transmission portion 81 along the axial direction of the first gear 80, that is, the second transmission portion 91 is disposed on the right side of the second gear 90, and the second transmission portion 91 is disposed on the path that the first transmission portion 81 passes when rotating, so that the second transmission portion 91 can drive the first transmission portion 81 to rotate when ensuring that the second gear 90 rotates.

It should be understood that the positions of the first transmission portion 81 and the second transmission portion 91 in this embodiment are not unique, and in other embodiments, the first transmission portion 81 may be disposed on the right side of the first gear 80, and the second transmission portion 91 may be disposed on the left side of the second gear 90, so long as the second transmission portion 91 can drive the first transmission portion 81 to rotate when the second gear 90 is ensured to rotate.

In this embodiment, as shown in fig. 7 to 10, two first transmission parts 81 are provided, and the two first transmission parts 81 are symmetrically disposed with respect to the rotation axis of the first gear 80, specifically, when viewed from the side, the two first transmission parts 81 are symmetrically disposed, and both the first transmission parts 81 can be driven to rotate by the second transmission part 91, so that the rotation effect is better.
