In addition the aforementioned axle bed 103 of person is installed with the centre at containing space 105, that is this axle bed 103 axially protrudes out formation from the framework 102 bottom side centre in this containing space 105, and is pivoted mutually with relative rotor 13.
Moreover aforementioned rotor 13 is provided with a wheel hub 131 and a plurality of blade 132, described blade 132 rings are located on the outer circumferential side of this wheel hub 131, and it is provided with a fixed end 1321 and from these fixed end 1321 outward extending free ends 1322, and this fixed end 1321 is fixed on relative wheel hub 131 all sides; And the space of this first inlet air side 1011 is greater than the diameter width of this wheel hub 131, and relative is exactly the air inlet area that increases this first inlet air side 1011, so as to reaching the effect that promotes air quantity.
Continuous consult Fig. 2, Fig. 3 shows, aforementioned magnetic part 15 is a magnet or a magnetic body, and it is located on the described blade 132, and establishes in the aforementioned magnetic part 15 of this better enforcement along free end 1322 continuous loops of described blade 132 and to consist of a magnetic ring body and explain, but is not limited to this; When the actual enforcement of the utility model, can change the enforcement aspect that magnetic part 15 and blade 132 integrally combine according to user's demand:
Wherein one to implement aspect be that the quantity that the quantity of aforementioned magnetic part 15 also can be mated described blade is done design, that is show such as Fig. 4, Fig. 5, this magnetic part is established formation along the free end 1322 discontinuous rings of described blade 132, in other words, be exactly that a plurality of magnetic part 15 Unitary injection formeds are on the free end 1322 of a plurality of blades 132 of correspondence.
Another implement aspect be as Fig. 6, Fig. 7 show this magnetic part 15 with as described in blade 132 Unitary injection formeds be a plurality of magnetic leafs, or can be a magnet rotor with described blade 132 and wheel hub 131 Unitary injection formeds with aforementioned magnetic part 15 also, close chat first bright.
Other is the person, this magnetic part 15 is axially responded to excitatory to a coil groups 161 that should stator 16 has mutually, so by these magnetic part 15 one-body molded designs on the free end 1322 of described blade 132, make it possible to strengthen the intensity of described blade 132, and more can increase the effect of motor torsion, and then can also reduce the vibration that blade 132 beats produce, and reach the effect that reduces noise.
Moreover when implementation, aforementioned magnetic part 15 can be considered single element, namely aforementioned magnetic part 15 with sticking/fit, chimeric, engaging and clamping arbitrary Placement wherein, be located on the free end 1322 of described blade 132, close first Chen Ming.
The continuous Fig. 3 that consults, stator former 16 is arranged between these fan frame 10 inboards and the described blade 132, and relatively described magnetic part 15, and this stator 16 is provided with aforementioned coil groups 161 and a circuit board 162, this circuit board 162 is located on the bottom side in this framework 102, and relative this axle bed 103, and be inserted with a plurality of electronic component (not shown) on this circuit board 162, described electronic component (such as capacitor, SCR, control wafer, transistor) is located on a part of end face of these circuit board 162 relative these lids 101, and is electrically connected with circuit board 162; These coil groups 161 windings and are electrically connected with this circuit board 162 on another part end face of these circuit board 162 relative these lids 101.
So be located at described blade 132 outer (namely in this containing space 105) by this stator 16, diminish so that can adjust the diameter width that changes this wheel hub 131, to shorten the space between this axle bed 103 and the wheel hub 131, the space of this relative the first inlet air side 1011 also can become large (i.e. the air inlet area change of the first inlet air side 1011) along with adjusting, and promotes with the fluid flow that effectively impels this first inlet air side 1011 to import.
So by the design of this fan motor structure 1 of the utility model, getting effectively increases blade 132 intensity and reaches lifting air quantity effect, and promotes motor outputting torsion and run stability, and then more can reach the effect that reduces fan vibration and vibrating noise.
In addition, fan motor structure 1 of the present utility model is when making, with stator 16 designs position between these fan frame 10 inboards and described blade 132, make the user can be according to the demand of required fan thinness, adjust the effect that the height that reduces this axle bed 103 and wheel hub 131 reaches better slimming, use effectively to reach and reduce the man-hour of assembling, convenient production and cost-effective effect.
See also Fig. 1, Fig. 8, Fig. 9 shows, shows combination and the decomposing schematic representation of the second preferred embodiment of the present utility model; The structure of this preferred embodiment and connection relationship and effect thereof are roughly identical with aforementioned the first preferred embodiment, mainly be that the magnetic part 15 of the first better enforcement is located on the free end 1322 of described blade 132, change and be designed to be located between the free end 1322 and fixed end 1321 of described blade 132, that is the magnetic part 15 of this better enforcement establishes along continuous loop between the free end 1322 of described blade 132 and the fixed end 1321 and consists of a magnetic ring body and explain, but is not limited to this;
The person is when the actual enforcement of the utility model in addition, the quantity that the quantity of aforementioned magnetic part 15 also can be mated described blade 132 is done design, that is show that such as Figure 10, Figure 11 described magnetic part 15 is established formation along discontinuous ring between the free end 1322 of described blade 132 and the fixed end 1321.
So by this magnetic part 15 one-body molded at described blade 132 free end 1322 and fixed end 1321 between the design of position, make it possible to strengthen the intensity of described blade 132, and more can increase the effect of motor torsion, and can also reduce the vibration that blade 132 beats produce, and reach the effect that reduces noise.
In addition, when implementation, aforementioned magnetic part 15 can be considered single element, namely aforementioned magnetic part 15 with sticking/fit, chimeric, engaging and clamping arbitrary Placement wherein, be located between the free end 1322 of described blade 132 and the fixed end 1321 on the position, close chat first bright.
See also Figure 12, Figure 13 shows, shows combination and the decomposing schematic representation of the 3rd preferred embodiment of the present utility model; The structure of this preferred embodiment and connection relationship and effect thereof are roughly identical with aforementioned first and second preferred embodiment, so again do not give unnecessary details at this, its both differences be in: aforementioned framework 102 relative these lid 101 1 sides are provided with one second inlet air side 1022, this the second inlet air side 1022 provides and is formed on adjacent this axle bed 103 on these framework 102 bottom sides, and it is communicated with this containing space 105 and air side 1021 and the first inlet air side 1011, and it is in order to increase the flow that imports fluid.
The above, the utility model has a following advantage compared to known:
1. has the effect that promotes air quantity;
2. the effect that has better slimming;
3. have the vibration of reduction and vibrating noise;
4. has the effect that strengthens blade strength.
Press, the above only is preferred embodiment of the present utility model, yet feature of the present utility model is not limited to this, and any those skilled in the art is in the utility model field, can think easily and variation or modification, all should be encompassed in following claims of the present utility model.
