Automotive air-conditioning system is to realize freeze to air in a car compartment, heat, taking a breath and the device of air purification.It can
To provide comfortably environment by bus for passenger, the fatigue strength of driver is reduced, improves traffic safety.With air conditioning for automobiles
Extensive use, requirement of the people to air conditioning for automobiles low energy consumption, low noise, comfort is got up higher, how not to reduce air-conditioning
On the basis of system capability, the noise of air-conditioning is reduced, comfort level is improved, is prior art problem to be solved.
Invention content
The technical problems to be solved by the invention are that in view of the deficiencies of the prior art, noise can be reduced, carry by providing one kind
For the air conditioner motor fan impeller structure of comfort.
In order to solve the above technical problems, the technical scheme is that：A kind of air conditioner motor fan impeller structure, including leaf
Wheel ontology, the blade being arranged on impeller body, the blade are arc shaped blade, and the blade is radially set along impeller
One end is inner end, and the other end is outer end, and blade inner end top shape is the first semi arch, and blade outer end top shape is the second half
Circular arc, the outside of first semi arch by three sections successively tangent arcuate structure connect with the outside of the second semi arch,
The inside of first semi arch by other three sections successively tangent arcuate structure connect with the inside of the second semi arch.
The radius of circle of first semi arch is more than the second semi arch radius of circle.
Three sections of arcuate structures are the first arc, the second arc, third arc, other three sections of arcuate structures
For the 4th arc, the 5th arc, the 6th arc.
The present invention using the above structure, has the following advantages：1st, noise can be reduced, comfort is provided；2nd, simplify different
The design process of diameter impeller mitigates the workload of designer, greatly improves work efficiency.

Specific embodiment
A kind of air conditioner motor fan impeller structure as shown in Fig. 1~Fig. 6 including impeller body 1, is arranged on impeller body 1
On blade 2, the blade 2 is arc shaped blade, the blade 2 along one end of impeller radially setting for inner end, the other end
For outer end, 3 top shape of blade inner end is the first semi arch 4, and 5 top shape of blade outer end is the second semi arch 6, described the
The outside of one semi arch 4 by three sections successively tangent arcuate structure connect with the outside of the second semi arch 6, described the first half
The inside of circular arc 4 by other three sections successively tangent arcuate structure connect with the inside of the second semi arch 6.Three sections of arcuate structures
For the first arc 7, the second arc 8, third arc 9, in addition three sections of arcuate structures are the 4th arc 10, the 5th arc the 11, the 6th
Arc 12.The radius of circle of first semi arch 4 is more than the second semi arch and justifies 6 radiuses, i.e. the thickness of blade 2 is passed through by blade inner end 3
Three sections of arcuate structures to blade outer end 5 is gradually reduced, and is proved through test of many times, which reduces noise when impeller uses.
In Fig. 4~Fig. 6, point O is impeller center axis projections point；Point A is a bit on impeller diameter circle；Point B is blade
Internal diameter circle on a bit；Point C and D is 2 points in line segment AB；Circle OA, OB are respectively impeller diameter circle and internal diameter blade circle；Circle
C, D is respectively the entrance and exit root circle of impeller shape；Line segment FG was C points and intersection point that is vertical with CE and intersecting at round C,
Point F, G are the point of contact with next section of circular arc respectively；Line segment HI was D points and intersection point that is vertical with DE and intersecting at round D, point H, I
It is the point of contact with next section of circular arc respectively；Arc radius is defined using CATIA software functions and design experiences, is respectively created successively
Arc 1,2,3,4,5,6；The length of AB line segments is defined, the length of AB line segments is proportional with impeller diameter, can establish parameter
Change design；Stretched impeller height (definition of height dimension parameterisable) in CATIA modelings, and created using circular arc array commands
Blade quantity (design of quantity parameterisable).The principle of the design method combination geometry designs, initially sets up triangular framing knot
Structure creates the shape of blade on the basis of frame structure, and CATIA Parametric designings module is recycled to carry out parametrization to impeller and is set
Meter.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as employing the various improvement of technical scheme of the present invention progress or not improved directly applying to other occasions
, within protection scope of the present invention.
