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 or similar 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 accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to 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 drive 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.
According to the air deflector driving assembly 1000 of the embodiment of the invention, the driving gear 110 is engaged with the first engaging portion 121 of the rack 120, the driven gear 130 is engaged with the second engaging portion 122 of the rack 120, and the power of the driving motor 300 can be transmitted to the air deflector 200, so that the motion stability and continuity of the air deflector driving assembly 1000 can be improved, and the motion stability of the air deflector 200 can be further improved.
In some embodiments of the present invention, as shown in fig. 1, the air deflection plate driving assembly 1000 further includes a base 400, and the transmission assembly 100 is disposed in the base 400. 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. Therefore, the first positioning hole 420 and the second positioning hole 124 can be used for positioning, for example, when the tool is used for installing the transmission assembly 100 and the base 400, the positioning component on the tool can penetrate through the first positioning hole 420 and the second positioning hole 124, so that the transmission assembly 100 and the base 400 can be conveniently assembled.
Referring to fig. 1-3, in some embodiments of the present invention, a retaining groove 430 is formed in the base 400, and the end of the rack gear 120 is disposed in the retaining groove 430. Thus, the rack gear 120 can be restricted by the restricting groove 430. It should be noted that, the number of the limiting grooves 430 is limited, for example, in some embodiments, there may be one limiting groove 430, and the limiting groove 430 may limit one end or both ends of the rack 120; for another example, in some embodiments, there may be two limiting grooves 430, one of the limiting grooves 430 may limit one end of the rack 120, and the other limiting groove 430 may limit the other end of the rack 120.
Further, as shown in fig. 1 to 3, a stop portion 431 is provided in the limiting groove 430, and the stop portion 431 contacts with a portion of the rack 120. It is understood that the stopping portion 431 may be formed by a portion of the sidewall of the limiting groove 430, and the stopping portion 431 contacts a portion of the rack gear 120 to limit the rack gear 120, so that the force applied to the rack gear 120 may be equalized, so that the rack gear 120 can move smoothly in the limiting groove 430.
According to some embodiments of the present invention, in conjunction with fig. 2, at least one of the rack 120 and the stopper 431 has an oil groove 125. It is understood that the rack 120 may have the oil groove 125, or the stopper 431 may have the oil groove 125, or both the rack 120 and the stopper 431 have the oil groove 125. The oil groove 125 may contain lubricating oil to lubricate between the rack 120 and the stopper 431. Further, referring to fig. 2, the oil groove 125 may be plural, and the plural oil grooves 125 are spaced apart in the moving direction of the rack gear 120. The plurality of oil grooves 125 spaced apart in the moving direction of the rack gear 120 may store more lubricating oil to make the movement of the rack gear 120 smoother.
In some examples as shown in fig. 4, the air deflection drive assembly 1000 may also include an upper housing 800. Wherein, the upper shell 800 is suitable for being buckled with the base 400 to form an installation space, and the transmission assembly 100 is located in the installation space. Referring to fig. 1 to 2, the surface of the rack gear 120 facing the upper case 800 and the surface of the rack gear 120 facing the base 400 may be provided with sliding portions 126, and when the rack gear 120 moves, the upper case 800 and the base 400 are stopped by the corresponding sliding portions 126, so that friction between the rack gear 120 and the upper case 800 and the base 400 may be reduced.
As shown in fig. 1, in some embodiments of the present invention, a roller 500 is disposed in the base 400, the roller 500 is disposed at one side of the rack 120, and the roller 500 abuts against an end of the rack 120. It should be noted that the roller 500 and the pinion 110 may be located on the same side of the rack 120, and the roller 500 may abut against the end of the rack 120, so that the roller may press the end of the rack 120, thereby improving the motion stability of the rack 120.
As shown in fig. 1, further, the base 400 has fixing posts 440. The air deflection drive assembly 1000 as shown in figures 1 and 2 may further include a compression torsion spring 600. Wherein, compress tightly the torsional spring 600 cover and locate fixed column 440, compress tightly the one end of torsional spring 600 and be connected with base 400, compress tightly the other end of torsional spring 600 and be connected with roller 500. Therefore, the fixing column 440 can position the compression torsion spring 600, so that the compression torsion spring 600 is reliably fixed on the base 400; the other end of the compression torsion spring 600 is connected with the roller 500, so that the roller 500 and the rack 120 have a pretightening force by using the pretightening force of the compression torsion spring 600, and the roller 500 can be in compression fit with the rack 120.
On one hand, when the rack 120 moves, the roller 500 applies a pressing force to the rack 120, which can reduce the friction between the rack 120 and the inner wall of the spacing groove 430; on the other hand, the pressing force applied to the rack 120 by the roller 500 can reduce the gap between the rack 120 and the driven gear 130, and the motion stability of the driven gear 130 can be improved in the process of the meshing transmission between the rack 120 and the driven gear 130, so that the rotation stability of the wind deflector 200 can be improved.
In the example shown in fig. 1-2, four driven gears 130 are provided, and in the length direction of the rack 120, the four driven gears 130 are respectively a first gear 131, a second gear 132, a third gear 133 and a fourth gear 134, wherein a pre-tightening spring 700 is provided between the first gear 131 and the second gear 132, and the pre-tightening spring 700 is provided between the third gear 133 and the fourth gear 134.
