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 Fig. 1 to 10, sweep air blade according to of the present utility model, comprise blade body 11, blade body 11 is provided with the pitman shaft 13 be rotationally connected with connecting rod 20, pitman shaft 13 extends along axis to the edge of blade body 11 and is fixedly connected with blade body 11.
Shown in 2a, 2b and Fig. 4 to 6, blade body 11 is general thinner, thickness is at about 1.5mm, add the characteristic of material itself, after making blade injection mo(u)lding, deflection is difficult to be guaranteed, integral rigidity is more weak, easily occurs that blade body stays defects such as distorting, causes outward appearance unsightly.Must increase blade rigid for improving deformable blade, that can do increases rib exactly and improves on blade, by increasing strengthening rib strip, can improve its rigidity, improving the distortion of blade body, appearance is beautified.
Similarly, because the thickness of blade body 11 is relatively thin, the diameter of relative pitman shaft 13 is less than normal, the fitting recess 12 coordinated with connecting rod 20 is set in blade body 11 like this, when fitting recess 12 arranges pitman shaft 13, the root that pitman shaft 13 is combined with blade body 11 will form step, stress is caused to concentrate, what the material that binding site between the two connects compared lacks, so when assembling connecting rod 20, if firmly pull blade, just easy from fracture of root at the effect lower link axle 13 of external force, if by the whole blade face of through for pitman shaft 13 blade body 11 or most of blade face, just can solve pitman shaft 13 Root Stress to concentrate, the problem that connecting material is few, the fillet that pitman shaft 13 is large with blade body 11 is also beneficial to the release of stress and the increase of intensity, effective improves the problem that pitman shaft 13 assembles fracture.
Above-mentioned two aspects combine by the utility model, even if pitman shaft 13 extends along axis to the edge of blade body 11 and is fixedly connected with blade body 11, thus make pitman shaft 13 run through most or all blade faces, and serve as the reinforcement of blade body 11, thus play the connectivity problem that solves pitman shaft 13 and blade body 11 and the inadequate problem of blade body 11 rigidity simultaneously.
Shown in composition graphs 2a to Fig. 5, Fig. 9 and Figure 10, arrange in form concrete, pitman shaft 13 can extend on the blade face, both sides of blade body 11, also can only extend on blade face, side as shown in Figure 2 a.Preferably, pitman shaft 13 and blade body 11 one-body molded, namely adopt integrated injection molding, convenient processing, also can improve bonding strength.
As shown in Fig. 2 a, 2b and Fig. 3, air blade of sweeping in the utility model is flexible blade, namely blade body 11 has flex region 14, the length direction of flex region 14 is parallel to the axis direction of pitman shaft 13, the width of flex region 14 is perpendicular to the axis direction of pitman shaft 13, in the process of connecting rod 20 drive link axle 13 movement, there is flexible bending in flex region 14, thus changes wind-guiding direction, blade face.Preferably, flex region 14 has the perforate 15 extended along its length, can play the effect of the elastic force reducing flex region 14, thus can reduce the size of the driving moment that flex region 14 is out of shape.
Shown in composition graphs 3, there is very large relation rotating torque and the flex region 14 of blade body 11, the width c of flex region 14 affects the radius of gyration, and indirect feedback is in the moment of blade, and c value is the bigger the better, but it is serious that the injection defect brought also compares, a rational width must be had, preferably, e1/4≤c≤e1/3, wherein, e is the length of flex region 14.
More preferably, perforate 15 is one, compared to the mode arranging multiple perforate 15, both the problem that the intermediate connections of multiple perforate ruptures can have been avoided, the moment needed for blade rotation can be reduced again, consider that the problem of glue is walked in bonding strength and injection moulding, the width a of perforate 15 is generally c1/4≤a≤c1/3.
Shown in composition graphs 3 and 8, the thickness of flex region 14 is d, can according to formula
calculate the length b of perforate 15, and the junction width at perforate two ends is divided equally relatively, effectively can solve the shaping problem of Shooting Technique, also make rotating torque reach a preferably level, wherein, M is for presetting moment simultaneously, the maximum rotation moment of sweeping wind stepper motor and providing is provided, E is the elastic model of the material of flex region 14, and y is the default bias amount of blade body 11, the general chord length of sweeping corresponding to wind angle adopting the supposition rotating shaft of blade shroud around flex region to turn over.Also, namely after the material that product function requires and flex region adopts is determined, M, E, y are definite value, thus can according to formula
be back-calculated to obtain the length b of perforate 15.
Described in composition graphs 1, Figure 11 and 12, the utility model additionally provides one and sweeps wind mechanism, comprise the electric machine assembly 40 of blade clamp 30, connecting rod 20 and drive link 20, blade clamp 30 is provided with and multiplely aforesaidly sweeps air blade 10, the pitman shaft 13 sweeping air blade 10 is rotationally connected with connecting rod 20, effectively can solve the inadequate problem of blade strength, also solve the problem that pitman shaft 13 root easily ruptures simultaneously.
Shown in Figure 12, connecting rod 20 has and rotates draw-in groove 21, pitman shaft 13 is connected to and rotates draw-in groove 21, thus connecting rod 20 and pitman shaft 13 are rotatably assorted, and driven vane swings and sweeps wind.
Shown in composition graphs 2a and 2b, Fig. 4 Fig. 5, blade clamp 30 is provided with hole clipping, sweeps the claw 16 air blade 10 being provided with and connecting and fixing with hole clipping, during assembling, make claw 16 pass hole clipping and be connected to the edge of hole clipping, reliably easy to connect.
Shown in composition graphs 1, the utility model additionally provides a kind of air-conditioner, comprises base 1, base 1 is provided with aforesaidly sweep wind mechanism, effectively can improve reliability.
As can be seen from the above description, the utility model the above embodiments achieve following technique effect:
