The above-mentioned fan assembly that is used for bicycle, described transmission device comprise first sprocket wheel, second sprocket wheel, chain, first sleeve, second sleeve, rotating shaft, first conical gear, second conical gear and flabellum rotating shaft.Second sprocket wheel is installed on the interior front-wheel hub of bicycle front fork and with front-wheel and rotates, second sprocket wheel is installed in the rotating shaft, rotating shaft is installed in second sleeve by second antifriction-bearing box, and second sleeve is fixed on the handle vertical pipe of bicycle (being the transition portion of vertical tube and handlebar).The other end of rotating shaft is equipped with first conical gear, and first conical gear and the engagement of second conical gear also drive flabellum rotating shaft rotation, and flabellum is installed in the flabellum rotating shaft.Be connected by chain gear between first sprocket wheel and second sprocket wheel.
The above-mentioned fan assembly that is used for bicycle, the flabellum rotating shaft is installed in first sleeve by first antifriction-bearing box, and first sleeve is fixed on the handlebar of bicycle, and flabellum is installed on the flabellum axle, rotates with second conical gear.
The above-mentioned fan assembly that is used for bicycle, second sprocket wheel are installed on the wheel hub of the front-wheel in the bicycle front fork and with front-wheel and rotate, and drive second sprocket wheel by chain.
The above-mentioned fan assembly that is used for bicycle, first conical gear drives the flabellum that the flabellum rotating shaft is rotated and drive is contained on this with the engagement of second conical gear and rotates.
The above-mentioned fan assembly that is used for bicycle, first sleeve and second sleeve are fixed on the handlebar of bicycle respectively and on the handle vertical pipe, in order to supporting revolving shaft and flabellum rotating shaft, and keep first sleeve vertical mutually with second sleeve.
The above-mentioned fan assembly that is used for bicycle, first sleeve and second sleeve and interior first antifriction-bearing box and second antifriction-bearing box of being equipped with respectively make rotating shaft and flabellum rotating shaft rotate flexibly.
The above-mentioned fan assembly that is used for bicycle, the number of teeth of first sprocket wheel should be less than the number of teeth of second sprocket wheel, and the ratio of the number of teeth of getting second sprocket wheel and the number of teeth of first sprocket wheel is 3: 1, like this when the bicycle front-wheel turns around, the flabellum rotating shaft just can obtain 3 times wind speed, produces more obvious cooling-down effect.
The utlity model has following advantage and effect.Based on above structure, bicycle fan and transmission device can drive the fan rotor rotation through chain-driving and Bevel Gear Drive with the power of bicycle itself, provide comfortable wind-force to the rider, reduce rider's sense of fatigue.This suitable new structure is simple, light and flexible, operates easily, and does not increase rider's burden.
Description of drawings
Fig. 1 is for being used for the structural representation of the fan assembly of bicycle in the utility model specific embodiment;
Fig. 2 is the assembling scheme drawing of second sleeve 5 in the utility model specific embodiment, rotating shaft 6, second sprocket wheel 7, second antifriction-bearing box 8 and first conical gear 9;
Fig. 3 is the assembling scheme drawing of first sleeve 3 in the utility model specific embodiment, flabellum rotating shaft 11, fan rotor 12, first antifriction-bearing box 2 and second conical gear 10.
The specific embodiment
Below in conjunction with concrete enforcement the technical characterictic of the utility model bicycle fan and transmission device is further described in detail.
At first, second sprocket wheel 14 is installed on the interior front-wheel hub of bicycle front fork, rotate with front-wheel, drive first sprocket wheel 7 that is positioned at bicycle headstock through chain-driving then, first sprocket wheel 7 drives rotating shaft 6 and rotates, rotating shaft 6 is parallel to each other with bicycle front axle 15 and is installed in second sleeve 5, and second sleeve 5 is fixed on the handle vertical pipe 4 of bicycle (being the transition portion of vertical tube and handlebar).The other end of rotating shaft 6 is equipped with first conical gear 9, thereby by the engagement of conical gear power is changed 90 ° of flabellum rotating shafts 11 rotations that drive in first sleeve 3, and first sleeve 3 is fixed on the handlebar 1 of bicycle.Flabellum rotating shaft 11 can make its upper part of the body that faces the rider by adjustable cone gear meshing direction, thus when having guaranteed that flabellum rotates over against rider's the upper part of the body, make the rider obtain comfortable cool breeze.
Because conical gear engagement is 90 ° of relations, therefore the rotating shaft in two sleeves and the sleeve is vertical mutually, and the rotating shaft in the sleeve all has roller bearings, makes it be easy to rotate.
Further describe the structure and the assembling of this fan assembly below.Shown in Fig. 1～3, bicycle fan and transmission device comprise:
Second sprocket wheel, 14, the second sprocket wheels 14 that are installed in the bicycle front fork connect firmly together with front-wheel hub, and second sprocket wheel 14 is also followed rotation when front-wheel 16 rotates.
Just driving the second vertical with it conical gear 10 when first conical gear 9 rotates rotates, second conical gear 10 connects firmly with flabellum rotating shaft 11, flabellum rotating shaft 11 is installed in first sleeve 3 by antifriction-bearing box 2, and first sleeve 3 then is fixed in the bicycle handle bar 1.The front end of flabellum rotating shaft 11 is equipped with fan rotor 12.
Therefore, the concrete working process of bicycle fan and transmission device is as follows:
When the rider rides bicycle, bicycle just rotates, second sprocket wheel 14 rotates at any time, drives first sprocket wheel 7 by chain-driving and rotates, and drives rotating shaft 6 and 9 rotations of first conical gear again, first conical gear 9 drives second conical gear 10 again and rotates, change sense of motion simultaneously, and drive flabellum rotating shaft 11 and the fan rotor 12 that is installed on this rotates, finally produce wind-force, make the rider obtain comfortable pleasantly cool cooling-down effect, reduce rider's sense of fatigue.
In sum as can be known, this suitable new structure is simple, installs easily, and is easy to operate, can not damage bicycle during installation, has very strong applicability.
