Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
An air deflection driving assembly 1000 and an air conditioner according to an embodiment of the present invention will be described with reference to fig. 1 to 5.
As shown in fig. 1-5, an air deflection assembly 1000 according to an embodiment of the present invention includes a transmission assembly 100 and a driving motor 300.
Specifically, as shown in fig. 1-2, the transmission assembly 100 includes a drive gear 110, a rack gear 120, and a driven gear 130. The driving gear 110 is located at one side of the rack gear 120, and the driven gear 130 is located at the other side of the rack gear 120. The driving motor 300 is connected to the driving gear 110 to drive the driving gear 110 to rotate. As shown in fig. 1, the rack gear 120 has a first engaging portion 121 and a second engaging portion 122, the first engaging portion 121 engages with the driving gear 110, and the second engaging portion 122 engages with the driven gear 130. Therefore, the driving motor 300 may drive the driving gear 110 to rotate, the driving gear 110 may transmit power to the rack gear 120, and the rack gear 120 may transmit power to the driven gear 130.
With reference to fig. 1 and 5, there are a plurality of driven gears 130, a plurality of air deflectors 200, and a plurality of air deflectors 200 correspond to the plurality of driven gears 130 one by one, that is, each driven gear 130 may be connected to one air deflector 200. It is understood that the driven gear 130 can provide power for the air deflector 200, and the rotation of the driven gear 130 can drive the rotation of the air deflector 200.
Further, the driven gear 130 is adapted to be connected with the air deflection plate 200. When the power is transmitted to the driven gear 130, the driven gear 130 rotates, and the driven gear 130 drives the air deflector 200 to rotate. It should be noted that the air deflector 200 may be used to shield or open an air outlet of the air conditioner, or the air deflector 200 may also change an air supply angle during the rotation process.
For example, as shown in fig. 1, the driving motor 300 may provide a power source for the driving gear 110 to drive the driving gear 110 to rotate, and the driving gear 110 drives the rack 120 to move linearly in the left and right directions (left and right directions as shown in fig. 1) by rotating. The rack 120 can drive the driven gear 130 to rotate by linear motion, and when the driven gear 130 rotates, the air deflector 200 can be driven to turn over, so that the air deflector 200 can open or close the air outlet. When the air deflector 200 opens the air outlet, the air flow in the air conditioner can flow out from the air outlet, and the air flow can be blown to different directions due to different opening angles of the air deflector 200; when the air deflector 200 closes the air outlet, the air flow in the air conditioner cannot be blown out from the air deflector 200.
Referring to fig. 1 and 5, when the driving motor 300 drives the driving gear 110 to rotate counterclockwise, the driving gear 110 drives the rack 120 to move to the right (as shown in fig. 1), the rack 120 drives the driven gear 130 to rotate clockwise, and the air deflector 200 opens the air outlet; when the driving motor 300 drives the driving gear 110 to rotate clockwise, the driving gear 110 drives the rack 120 to move to the left (left as shown in fig. 1), the rack 120 drives the driven gear 130 to rotate counterclockwise, and the air outlet of the air deflector 200 can be closed.
In the correlation technique, the wind guide strip transmission structure mostly adopts the driving gear to rotate and drive the driven gear to rotate, the driven gear drives the output gear to rotate again, the output gear is connected with the wind guide strip, the output gear drives the wind guide strip to rotate so as to realize the opening and closing of the wind guide strip, the wind guide strip transmission structure has a gap between the gears, the rotation of the output gear lags behind the rotation of the driving gear in the transmission reversing process, and therefore the discontinuous motion state appears between the gears, and the rotation of the wind guide strip is not stable.
And according to the utility model discloses aviation baffle drive assembly 1000, through the meshing of the first meshing portion 121 that makes driving gear 110 and rack 120, make driven gear 130 and the meshing of the second meshing portion 122 of rack 120, can drive motor 300's power transmission to aviation baffle 200, can promote aviation baffle drive assembly 1000 motion stability and continuity from this, and then can promote the stationarity of aviation baffle 200 motion.

Thus, the base 400 may provide an installation environment for the transmission assembly 100 to protect the transmission assembly 100 and prevent the transmission assembly 100 from interfering with other components.
Further, as shown in fig. 1-2, a limiting column 410 is provided in the base 400, the rack 120 has a travel groove 123, and the limiting column 410 is disposed through the travel groove 123 to limit the movement travel of the rack 120. When the rack 120 moves to the limit position to the right (the right as shown in fig. 1), the limit column 410 stops against the inner wall of the left side (the left as shown in fig. 1) of the travel groove 123; when the rack 120 moves to the limit position leftward (leftward as viewed in fig. 1), the stopper 410 abuts against the inner wall of the right side (rightward as viewed in fig. 1) of the stroke groove 123. Therefore, in the moving process of the rack 120, the stroke of the rack 120 can be limited by the matching of the limiting column 410 and the stroke groove 123, and the moving stability of the rack 120 can be further improved.
To facilitate installation of the transmission assembly 100 into the base 400, in some embodiments, as shown in fig. 1-2, the base 400 has a first positioning hole 420, and the rack 120 has a second positioning hole 124 corresponding to the first positioning hole 420.
