Description
Technical field
The utility model relates to bicycle art, refers in particular to a kind of bicycle generating set.
Background technology
Bicycle is a kind of pure physical construction, but wheel is in the state rapidly rotated under steam, has a large amount of kinetic energy; People when night running because bicycle does not install supply unit, cause throwing light on, easily cause danger, and outing in the wild or long-term by bike time always can run into the situation that the electrical equipment such as mobile phone do not have electricity, for this reason, we have developed a kind of bicycle generating set, can not only provide illumination when night running, can also to electrical equipment chargings such as mobile phones.
Utility model content
The utility model object provides a kind of bicycle generating set to overcome the deficiencies in the prior art, can not only provide illumination when night running, can also to electrical equipment chargings such as mobile phones.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bicycle generating set, comprises power generation assembly, rectifying circuit, storage battery and is arranged on lamp, the USB interface of headstock; Described storage battery is respectively with lamp be connected; Described power generation assembly comprises the housing be fixed on vehicle frame; Be provided with multi-disc circumferencial direction in described housing evenly to place and the piezoceramic that is all connected with inner walls of one end, the middle part of described housing is also provided with the pivot shaft of horizontal positioned; One end of described pivot shaft is arranged in housing, and the other end stretches out housing and is fixed on the turning cylinder of wheel; Described pivot shaft is also provided with the sword tooth contacted with every sheet piezoceramic; The power storage that power generation assembly produces by described rectifying circuit gives lamp in storage battery, USB interface is powered.
Preferably, switch is respectively arranged with between described storage battery and lamp, USB interface.
Preferably, one end of described pivot shaft is arranged in housing by bearing.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Bicycle generating set described in the utility model is dialed piezoceramic by vehicle wheel rotation and is produced electric energy, can not only provide illumination when night running, to electrical equipment chargings such as mobile phones, thus can also save electric energy, and green safety.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the schematic diagram of bicycle generating set described in the utility model;
Accompanying drawing 2 is the front view of power generation assembly in bicycle generating set described in the utility model;
Accompanying drawing 3 is A-A place cutaway view in Fig. 2;
Wherein: 1, housing; 2, sword tooth; 3, piezoceramic; 4, pivot shaft; 5, bearing.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1-3 is bicycle generating set described in the utility model, comprises power generation assembly, rectifying circuit, storage battery and is arranged on lamp, the USB interface of headstock; Described storage battery respectively with lamp be connected, and storage battery and lamp, is respectively arranged with switch between USB interface by electric wire, conveniently controls; Described power generation assembly comprises the housing 1 be fixed on vehicle frame; Be provided with six circumferencial directions in described housing 1 evenly to place and the piezoceramic 3 that is all connected with housing 1 inwall of one end, the middle part of described housing 1 is also provided with the pivot shaft 4 of horizontal positioned; One end of described pivot shaft 4 is arranged in housing 1 by bearing, the other end stretches out housing 1 and is fixed on the turning cylinder of wheel, and described pivot shaft 4 is also provided with the sword tooth 2 contacted with every sheet piezoceramic 3 other end, when vehicle wheel rotation, drive sword tooth 2 rotate and constantly dial piezoceramic 3 by pivot shaft 4, now piezoceramic 3 just can be produced electric energy and is stored in storage battery by rectifying circuit and powers to lamp, USB interface.
Night by bike time, turning on light switch, that lamp is obtained is electric, can provide illumination.
Outing in the wild or long-term by bike time, open interface switch, can also to electrical equipment chargings such as mobile phones.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Bicycle generating set described in the utility model is dialed piezoceramic by vehicle wheel rotation and is produced electric energy, can not only provide illumination when night running, to electrical equipment chargings such as mobile phones, thus can also save electric energy, and green safety.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
