For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of high speed spline diversion fan, comprise motor, also comprise and coaxially to arrange with the rotating shaft of motor and can relative to the loose collar of axis of rotation, the elastic force apparatus can be installed on the blade on loose collar around himself axis rotationally, provide return elastic force to blade, making blade become zero degree to arrange with the rotating shaft of motor and driven, overcome the return elastic force of blade by motor and the angle of the rotating shaft of blade and motor changed and drives the driver plate that loose collar rotates.
As limitation of the invention, blade is fixed with and is positioned at loose collar inside and the plectrum stirring this blade rotation, described elastic force apparatus is the spring being arranged on loose collar inside, and one end of this spring is connected in the reset post in loose collar, and the other end is connected with plectrum.
Limit again as to of the present invention, driver plate is provided with the draw-in groove being combined with plectrum, driving plectrum to rotate.
As to further restriction of the present invention, described driver plate is linked in the outer end of loose collar.
Limit further again as to of the present invention, be provided with in loose collar and spacing limited post is carried out to the corner of plectrum.
Further limit as to of the present invention, described blade has 3 to 6 along the periphery wall circle distribution of loose collar.
Present invention provides a kind of radiator, comprise radiator body, radiator body is provided with above-mentioned high speed spline diversion fan.
Present invention also offers a kind of automobile, it has above-mentioned radiator.
Owing to have employed above-mentioned technological scheme, the present invention compared with prior art, acquired technological progress is: in high speed spline diversion fan provided by the present invention, radiator and automobile, because fan makes blade become zero angle to arrange with rotating shaft by elastic force apparatus, avoid the effect of high velocity air to blade, can not rotate at high speeds, reduce windage simultaneously; Adopt spring as elastic force apparatus and coordinate with plectrum, simple and reliable for structure; Driver plate arranges draw-in groove be combined with plectrum, compact structure, be convenient to processing; Driver plate is linked in the outer end of loose collar, can seal loose collar; Arranging limited post can the hard-over of limit blade, avoids draw-in groove and plectrum to be separated.
The present invention is applicable in various automobile, reduces the noise of automobile when running at high speed and windage.
The present invention is described in further detail below in conjunction with Figure of description and specific embodiment.

Embodiment
embodimenta kind of high speed spline diversion fan, radiator and automobile
1. a kind of high speed spline diversion fan
As shown in Figure 1 to Figure 3, the high speed spline diversion fan of the present embodiment, comprise motor 1, arrange and the loose collar 2 that can rotate relative to rotating shaft 8 with the rotating shaft 8 of motor 1 is coaxial, the elastic force apparatus can be installed on the blade 3 on loose collar 2 around himself axis rotationally, provide return elastic force to blade 3, blade 3 and the rotating shaft 8 one-tenth zero degree of motor 1 being arranged and driven, overcome the return elastic force of blade 3 by motor 1 and blade 3 is changed and the driver plate 4 driving loose collar 2 to rotate with the angle of the rotating shaft of motor 1.Blade 3 adopts plate or two sides symmetrical structure, and when it and rotating shaft 8 one-tenth zero angle, high velocity air can not promote it.
Blade 3 is fixed with and is positioned at loose collar 2 inside and the plectrum 5 stirring the rotation of this blade 3, and elastic force apparatus is the spring 6 being arranged on loose collar 2 inside, one end of this spring 6 is connected in the reset post 10 in loose collar 2, the other end is connected with plectrum 5, when spring 6 is in free state, blade 3 and rotating shaft 8 one-tenth zero degree, if now driver plate 4 pairs of blades 3 are stirred, it will change the angle of blade 3, air-flow is produced when enabling it rotate, now spring 6 also will produce due to the rotation of blade 3 and be in extended state, produces elastic force.
In order to stir blade 3, driver plate 4 is provided with draw-in groove 7, this draw-in groove 7 combines with plectrum 5, and its width is greater than plectrum 5.When the rotating shaft 8 of motor 1 drives driver plate 4 to rotate, draw-in groove 7 stirs plectrum 5, plectrum 5 is made to rotate certain angle, now blade 3 rotates identical angle under the drive of plectrum 5, along with rotating shaft 8 is rotated further, driver plate 4 drives loose collar 2 to rotate by the effect of draw-in groove 7 and plectrum 5, thus makes blade 3 can pectinid.When the rotating shaft 8 of motor 1 stops operating, the elastic force effect of spring 6 makes blade 3 reset, again with rotating shaft 8 one-tenth zero degree.In order to avoid the corner of blade 3 is excessive, the draw-in groove 7 now on driver plate 4 may be separated with plectrum 5, is provided with and carries out spacing limited post 9 to the corner of plectrum 5 in loose collar 2, and after plectrum 5 contacts with limited post 9, blade 3 reaches hard-over.
Dust-proof in order to carry out, this driver plate 4 is linked in the outer end of loose collar 2, and the gap of it and loose collar 2 is less, avoids the inside that dust enters into loose collar 2.And blade 3 generally can have 3 to 6 along the periphery wall circle distribution of loose collar 2, in the present embodiment, be adopted as 6 of circle distribution.
2. a kind of radiator (not shown)
This radiator comprises radiator body, and namely the above-mentioned high speed spline diversion fan of the present embodiment is arranged on radiator body, for carrying out exhausting to radiator body.
3. a kind of automobile (not shown)
This automobile is provided with aforesaid radiator, for cooling the motor of automobile.
