Abstract
The invention discloses a bionic inlaid composite blade. The bionic inlaid composite blade comprises a hub and single blade bodies. Each single blade body is composed of a root, a middle section and a tail section. The thickness of the roots and the thickness of the tail sections are larger than the thickness of the middle sections, so that grooves attached with flexible fleecy fabrics are formed in the middle section areas on the single blade bodies. According to the bionic inlaid composite blade, the shape of wings of birds is used for reference, the front surfaces, the back surfaces and the corners of the blade bodies are all designed in an arc-shaped mode so that friction can be reduced, and thus the air resistance on the blade during operation is reduced to the greatest extent; and the flexible fleecy fabrics (or other flexible materials) are attached to the surfaces of the single blade bodies by adopting an inlaid means, noise can be absorbed, and wind noise is further reduced.
Description
Technical field
The invention belongs to fluid machinery technical field is and in particular to a kind of fan part, particularly a kind of bionical inlay multiple
Hing straps.
Background technology
The variously-shaped blade that domestic rotary fan is used at present, during operating generally existing wind make an uproar greatly, air-supply away from
From short problem.
Most thickness uniformly, radian is also not changed in these blades, this structure design makes fan not in design
Only wind is made an uproar big and air supplying distance is limited；Additionally, all fans all do not inlay the flexible napped material of attachment in blade surface, in addition
Most of blade weight counterbalances are uneven, thus producing very big vibration when fan rotates, lead to wind to be made an uproar high.
Wind is made an uproar when the fan blade being to rotate occurs and rubs with air and is produced.Wind is made an uproar and can be made us feeling not quite the thing, especially
It is that sense of discomfort is even more serious when fan continuously runs for a long time.
Therefore, intra vane manufacturer of current state and terminal use to be all badly in need of a kind of make an uproar less, air supplying distance of wind farther
Leaf product.
Content of the invention
The purpose of the present invention is made an uproar and is increased fan air-supply distance it is proposed that a kind of bionical inlay precisely in order to reducing fan wind
Composite blading, uses for reference birds assistant profile, can reduce the air drag being subject to during blade movement to greatest extent.
The invention provides a kind of bionical preparation blade, including wheel hub and single blade；Described single blade by root, in
Section and rear composition；Wherein, the thickness of described root and described rear is more than the thickness in described stage casing, thus in described single blade
Upper described stage casing region forms the groove of the flexible pile of attachment.
Described rear periphery is made up of some curved surfaces；Along described root outwardly direction, described some curved surfaces form one
Tip, the direction of described tip is contrary with the direction of rotation of described blade.
One of the described some curved surfaces contour line of curved surface is tangent with the direction of rotation of described blade.
The periphery in described root and described stage casing is constituted by curved surface.
The upper curved surface of described single blade is generally bent downwardly.
The both sides curved surface of described single blade generally to deviate from direction of rotation bending.
Along described hub radius outwardly direction, described root and described stage casing are gradually upturned along curve, and in institute
State rear to bend gradually downward along curve.
Described root, described stage casing and described rear are integrally formed.
The periphery of described wheel hub is provided with the groove that can embed described root.
Described root is fastened on described wheel hub by welding or by screw.
Described wheel hub central authorities have a through hole that can be inserted in rotary shaft.
Compared with prior art, a kind of bionical preparation blade of the present invention, uses for reference birds assistant profile, blade is just
Face, the back side, corner all using cambered design, to reduce friction, thus the air that is subject to when reducing blade movement to greatest extent
Resistance；Designed using 3D and change traditional blades structure, make blade weight counterbalance more accurate, produce when reducing blade movement further
Vibration, reduces the purpose that wind is made an uproar.
The single blade surface of the present invention is attached with flexible pile (or other flexible materials) using inlaying means, permissible
Low wind noise, drops in absorption noise further.
The present invention also making air-supply more concentrate the improvement of fan balde structure, being difficult to spread, thus effectively increasing simultaneously
Air supplying distance.
Additionally, blade material adopts TPEE elastomeric material, or ABS, PA, PP, PC Polymer material, or light-weight metal
Material, to mitigate leaf weight, effectively reduces the energy consumption of fan electromotor, improves fan effect.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail：
The invention provides a kind of bionical preparation blade, including wheel hub 1 and single blade 2；Described single blade 2 is by root
3rd, stage casing 4 and rear 5 form；Wherein, the thickness of described root 3 and described rear 5 is more than the thickness in described stage casing 4, thus
In described single blade 2, described stage casing 4 region forms the groove of the flexible pile of attachment.
Described rear 5 periphery is made up of some curved surfaces；Along described root 3 outwardly direction, described some curved surfaces form one
Individual tip, the direction of described tip is contrary with the direction of rotation of described blade.
One of the described some curved surfaces contour line of curved surface is tangent with the direction of rotation of described blade.
The periphery in described root 3 and described stage casing 4 is constituted by curved surface.
The upper curved surface of described single blade 2 is generally bent downwardly.The quantity of this single blade is odd number piece it is preferable that such as
Fig. 1 show 7.
The both sides curved surface of described single blade 2 generally to deviate from direction of rotation bending.
Along described wheel hub 1 radius outwardly direction, described root 3 and described stage casing 4 are gradually upturned along curve, and
Described rear 5 bends gradually downward along curve.
Described root 3, described stage casing 4 and described rear 5 are integrally formed.
The periphery of described wheel hub 1 is provided with the groove that can embed described root 3.
Described root 3 is fastened on described wheel hub 1 by welding or by screw.
Described wheel hub 1 central authorities have a through hole that can be inserted in rotary shaft.
Single blade 2 surface of the present invention is attached with flexible pile (or other flexible materials) using inlaying means, can
To adsorb noise, low wind noise drops further.
The present invention also making air-supply more concentrate the improvement of fan balde structure, being difficult to spread, thus effectively increasing simultaneously
Air supplying distance.
Noise test result shows, under conditions of same size, same rotational speed, bionical preparation blade compares conventional leaf
Piece lower noise 52% (being shown in Table 1).Due to the special construction of blade, air supplying distance also increases to 10 meters by 5 meters of common blade
(it is shown in Table 2) above.
Table 1 running noise is tested
