Description
Technical field
The present invention relates to a kind of bicycle generating set.
Background technology
Along with the consciousness of people's low-carbon (LC) is more and more stronger, increasing people has joined ranks by bike, has reduced on the one hand the discharge of carbon, has also tempered on the other hand health.
Now people more and more be unable to do without mobile device, and existing mobile device is also more and more, as mobile phone, MP4, digital camera etc., the power consumption of these equipment is increasing, cause mobile device regular do not have an electricity.The situation of particularly going out by bike, if mobile device has not had electricity, will be a very thing of headache.If can be by the kinetic transformation of bicycle electric energy to charging of mobile devices, that will greatly facilitate the convenience of going out by bike.
Prior art discloses a kind of bicycle hub generator, see that application number is 200410007841.1 Chinese patent, this bicycle hub generator comprises the wheel hub shell of a wheel, one axletree, one power coil and a power supply terminal, the wheel hub shell of this wheel is fixed with magnet, these axletree two ends are outstanding from the wheel hub shell of this wheel, rotate the wheel hub shell of support wheel freely, this power coil is positioned at the wheel hub housing exterior of this wheel, the supply line connected by this power coil and powering, the wheel hub housing exterior that makes the ground connection of power coil provide the earth terminal of use to be located at wheel by supply line.Above technology has very large shortcoming, need to change wheel hub during namely with bicycle-driven generation, and the wheel hub of different bicycles can't be general, and only only has power generation assembly, also there is no the electric energy processing equipment, should use cost high and very inconvenient.
Prior art discloses a kind of power generation assembly of bicycle, see that application number is 201010501465.7 Chinese patent, this device comprises rolling disc with permanent magnet and the shell of a U-shaped cavity, this device will be arranged on rolling disc on wheel hub in use, shell also will be arranged on cycle rack simultaneously, during installation, also will make rolling disc just in time be in the middle of the U-shaped cavity, installation process bothers very much.
Prior art discloses a kind of bicycle generating set, see that application number is 200810173217.7 Chinese patent, this device has a lead agency with drivening piece, drivening piece is arranged on cycle hub, drivening piece drives after lead agency rotates the transmission shaft that drives electrical generator and rotates, then power facility generates electricity, and electrical generator is arranged on the support of a side of wheel.Although this device has solved the problem that needs to change wheel hub, this technology has following shortcoming: this device is installed and is needed first mounting strap actuation mechanism, then electrical generator is installed, the former device of complex installation process and installation is many.And generator position easily occurs depart from and make whole device et out of order in the vibrations process of riding.
Prior art discloses a kind of bicycle generating set, see that application number is the Chinese patent of 201010125116.X, this device includes a holding device, this holding device is provided with several hook grooves, this hook groove hooks is located at bicycle spoke, and the concyclic heart of this driving wheel and bicycle shaft, the outer peripheral face of this driving wheel is provided with a drive section, this electrical generator includes a flower wheel, this flower wheel outer peripheral face is provided with a linkage part, the linkage part of this flower wheel is driven and is rotated by this driving wheel drive section, and this flower wheel drives this electrical generator generating.Although this device has solved the problem that needs to change wheel hub, need to one concentric driving wheel be installed in wheel hub, more loaded down with trivial details.After installing simultaneously, also an electrical generator will be installed on cycle rack, the position that will adjust simultaneously electrical generator and driving wheel makes it good fit, and installation process is quite loaded down with trivial details.And generator position easily occurs depart from and make whole device et out of order in the vibrations process of riding.
In sum, the power generation assembly of existing bicycle is all to produce electric energy after after the rotation of cycle hub drive transmission device is rotated, driving power facility again, but prior art also exists difficulty is installed in the design of the transmission device of bicycle generating set, install the problems such as rear easy et out of order.
Summary of the invention
The technical problem to be solved in the present invention, be to provide a kind of bicycle generating set.Solve existing bicycle generating set the problems such as loaded down with trivial details, the rear easily et out of order of installation are installed.
The present invention is achieved in that a kind of bicycle generating set, comprises power facility and transmission device, and described transmission device and power facility are in transmission connection,
Described device also comprises shell, and described power facility and transmission device are arranged in described shell;
Described transmission device comprises first order power wheel, described first order power wheel and power facility are in transmission connection, the side of described shell at first order power wheel place has one be used to passing the opening of wheel hub, described first order power wheel has an end face with the tight transmission of wheel hub one side pressure at described opening part, the center of described first order power wheel has one be used to passing the first through hole of wheel shaft, and a described shell side relative with described opening has one be used to passing the second through hole of wheel shaft.
In the bicycle generating set of the invention described above, because each assembly of this device all is arranged on enclosure, avoided discrete assembly in the cycling process, to shake the displacement caused, thereby the bad problem that causes assembly to damage of each assembly transmission has occurred.Also avoided simultaneously the fine pieces such as sand to enter drive disk assembly and cause the drive disk assembly transmission bad.Device of the present invention is when installing and using, first cycle wheel is unloaded, shell aperture of the present invention place is faced to wheel hub, make wheel shaft pass the first through hole of the first power wheel and the second through hole of shell, wheel hub passes the opening of shell one side, then again cycle wheel and this device is reinstalled to bicycle rack.Vehicle frame makes the wheel hub end face of first order power wheel and wheel hub one end realize the compression transmission to the extruding of apparatus of the present invention, has solved existing bicycle generating set and has installed loaded down with trivial detailsly, is not suitable for the problem of plurality of bicycles wheel hub.
As a kind of preferred structure of first order power wheel of the present invention, described end face is the plane of surface attachment one deck flexible media.The plane of flexible media has increased the friction coefficient between first order power wheel and wheel hub, makes the rotational of wheel hub after well, drive the rotation of first order power wheel.So long as flexible media all is fine, as rubber, cortex or soft plastic, because flexible media can increase friction force under same pressure.Flexible media of the present invention preferably adopts rubber, and the rubber cost is low, and friction coefficient is large, is easy to produce.Groove or striped energy increasing friction force equally is set certainly on end face, although friction force does not have flexible media large like that, groove or striped is set more easily realizes on end face, also save cost.
