Detailed description of the invention
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figures 4 to 7, according to air conditioner wind-guiding mechanism of the present utility model lifting driven unit, comprising: fixed support 43, for being fixedly connected with air-conditioning body; Tooth bar 41, relative fixed support 43 is vertically mounted slidably, and the lower end of tooth bar 41 is used for being connected with air conditioner wind-guiding mechanism; Gear train, is arranged on fixed support 43, and engages with tooth bar 41; Drive motors 44, is fixed on fixed support 43, and the driving gear 42 in drive gear set rotates, and the motor shaft 44a of drive motors 44 and the transmission of driving gear 42 matched in clearance.The utility model is by making motor shaft 44a and the transmission of driving gear 42 matched in clearance of drive motors 44, the i.e. junction of motor shaft 44a and driving gear 42 only transmitting torque, do not transmit moment of flexure, thus avoid the gravity of wind guiding mechanism 3 to be applied on drive motors 44 by driving gear 42, and then can wearing and tearing be reduced, improve electrical machinery life.
Preferably, fixed support 43 has bending resistance square supporting construction, bending resistance square supporting construction is formed the gear shaft of gear train and supports, namely by other supporting construction, support is formed to gear shaft, further can reduce the moment of flexure that gear-bearing is subject to, and then the moment of flexure also can gear self gravitation being avoided to produce in certain degree is transferred on the motor shaft 44a of drive motors 44, reduce gravity to the impact of electrical machinery life.
Particularly, shown in composition graphs 5 to 7, bending resistance square supporting construction comprises support set, and support set is set on the outer peripheral face of gear shaft, thus forms support to gear shaft.
More specifically, tooth bar 41 comprises and arranging in opposite directions and the first tooth bar be fixedly connected with and the second tooth bar; Gear train comprises intermeshing driving gear 42 and driven gear 46, and driving gear 42 and driven gear 46 are arranged between the first tooth bar and the second tooth bar and driving gear 42 engages with the first tooth bar, and driven gear 46 engages with the second tooth bar.By arranging two toothed rack 41, and respectively with gears meshing, make the stressed half for wind guiding mechanism gravity of each gear bar and gear shaft, namely reduce the carrying of each gear shaft, also can reduce the impact of gravity on motor shaft to a certain extent.In addition, adopt two toothed rack, also can make stressed symmetry, ensure stable drive, improve reliability.
In conjunction with shown in 5 to 7, support set comprises the first support set 43c, and the gear shaft of driving gear 42 is located in the first support set 43c, and rotatably coordinates with the inner peripheral surface of the first support set 43c.Namely the first support set 43c is formed driving gear 42 and supports, and bears the gravity of wind guiding mechanism and the moment of flexure of gravity generation, avoids moment of flexure being delivered on motor shaft by driving gear.
Support set also comprises the second support set 43b, and the second support set 43b is similar to the first support set 43c and acts on driven gear 46; Namely the gear shaft of driven gear 46 is located in the second support set 43b, and rotatably coordinates with the inner peripheral surface of the second support set 43b, thus forms support to driven gear 46.
Preferably, bending resistance square supporting construction also comprises back shaft 43a, back shaft 43a and the second support set 43b coaxial line sheathed; The gear shaft of driven gear 46 is provided with the axis hole coordinated with back shaft 43a.Namely the gear shaft of driven gear 46 is cannula-like, is plugged in the space that formed between back shaft 43a and the second support set 43b, further can improves reliability.
Preferably, tooth bar 41 and drive motors 44 generally lay respectively at the both sides of fixed support 43, and the motor shaft 44a of drive motors 44 passes fixed support 43 and drives with driving gear 42 and is connected, thus facilitates tooth bar 41 and drive motors 44 to arrange, and makes more compact structure.
Shown in composition graphs 5, air conditioner wind-guiding mechanism lifting driven unit also comprises motor cover 45, and motor cover 45 is arranged on the side of drive motors 44 away from fixed support 43, and with fixed support 43 secure fit, thus spacing fixing to drive motors 44.
Composition graphs 1 to 7 illustrates assembling process and the operation principle of lifting driven unit of the present utility model.
As shown in Figure 1, the air-supply panel assembly of air-conditioning is arranged on kitchen ceiling, and when air-supply panel assembly does not work, it is inner that wind guiding mechanism is positioned at housing 2, wind deflector Close All.Wherein air-conditioning internal machine is coupled together by flexible pipe and the air inlet 1 on air-supply panel assembly, realizes transporting cold wind.
As shown in Figure 2, when air-supply panel assembly is started working, wind guiding mechanism 3 drops to certain distance by coupled fixing lifting driven unit 4 and starts to sweep pneumatic work.Drive motors 44 in lifting driven unit 4 drives driving gear 42 to rotate by motor shaft 44a, driving gear 42 engages with the first tooth bar 41a in tooth bar 41 and driven gear 46 respectively, and driven gear 46 engages with the second tooth bar 41b in tooth bar 41, thus drive tooth bar 41 elevating movement, drive wind deflector to realize rising and declining.
At wind guiding mechanism under whole ascending, descending process and static off position, the weight of itself is all applied on back shaft 43a and motor shaft 44a with the weight being attached thereto the tooth bar connect, the weight of both each carrying half, this is concerning motor, also need while outputting torsion to bear Action of Gravity Field, consequent active force, can act in the reduction gearing of motor internal further, greatly can shorten the life-span of drive motors 44.For the problem that solution drive motors 44 life-span is short, then need to solve and eliminate the weight be applied on motor shaft 44a, drive motors 44 only needs outputting torsion, the carrying effect no longer outside commitment.
The utility model arranges the first support set 43c by the position corresponding to motor shaft 44a on fixed support 43, motor shaft 44a and driving gear 42 are designed to matched in clearance, now, be applied to the weight on motor shaft 44a, then born by the first support set 43c, similarly, second support set 43b and back shaft 43a is set, driven gear is formed and supports, thus make motor shaft 44a no longer carry the moiety by weight of wind guiding mechanism, only be responsible for outputting torsion, ensure that the life-span of drive motors 44.
