Abstract

The utility model relates to a bicycle power generator, which comprises a fixed seat and a disc, wherein the fixed seat is arranged on the bicycle frame, the disc is rotatably arranged on a bicycle rotating shaft, an accommodating space is formed on the fixed seat, the accommodating space comprises two opposite wall surfaces, at least one stator is arranged in the fixed seat to be adjacent to one wall surface, each stator is provided with a line shaft and an induction coil, a part of the disc is positioned in the accommodating space, a plurality of permanent magnets used as rotors are embedded and arranged on the disc, and the permanent magnets are ranged into a circle. When each permanent magnet enters the accommodating space, two magnetic poles of the permanent magnets respectively face the two opposite wall surfaces of the accommodating space, and the induction coil generates induced current when the permanent magnets enter the accommodating space. Thereby, the induction coil can supply the power for a connected electronic device.

Description

Bicycle generating set

Technical field

The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), relates in particular to a kind of bicycle generating set that generates electricity by magnetic element generation induced current.

Background technology

Recently bicycle has become popular body-building apparatus, carries out in the mode that need not additionally expend electricity, the oily energy also being available for users to carry out long-time aerobic exercise, and then reaching body-building effect convenient the moving of short distance or intermediate range except the user is provided.

Yet night, contiguous car or locomotive driving were difficult to realize the approaching of bicycle when driving bicycle, thus the car or the problem of locomotive accidental impact bicycle take place easily, so drive the dangerous high of bicycle night.

In order to drive fail safe the night of improving bicycle, someone can carry some personal electric communication articles for use or install light fixture on bicycle, yet, there is no Blast Furnace Top Gas Recovery Turbine Unit (TRT) on the bicycle, when these personal electric communication articles for use light fixtures need extra connection battery or charging competence exertion function, the user must replace additional power supply often, very inconvenience.

The utility model content

Technical problem underlying to be solved in the utility model is, overcome the shortcoming that existing bicycle lacks Blast Furnace Top Gas Recovery Turbine Unit (TRT), and provide a kind of bicycle generating set, it can produce electric power when the user drives bicycle, and then provides electric power to light fixture or the miscellaneous equipment that is connected on the bicycle generating set.

For achieving the above object, be to make aforementioned bicycle generating set have a holder and that is arranged on the bicycle frame be arranged on disc in the bicycle rotating shaft with rotary way, wherein:

Be formed with an accommodation space on this holder, this accommodation space has two relative walls, is provided with at least one stator with an adjacent wherein wall in holder, and each stator has a bobbin and an induction coil;

This disc part is positioned at accommodation space, on disc, be embedded with several permanent magnets as rotor, permanent magnet is arranged lopping in the concentric circles mode, when each permanent magnet enters accommodation space, towards two relative walls of accommodation space, permanent magnet turnover accommodation space induction coil in season produces induced current to two magnetic poles of permanent magnet respectively.

By above-mentioned technological means, the relative motion of induction coil and permanent magnet, cause the magnetic flux change on the induction coil, thereby induction coil can produce induced current, therefore, bicycle generating set promptly is that the kinetic energy with permanent magnet is converted to electric energy, is connected to electronic installations such as LED when induction coil, can power to electronic installation.

The aforementioned fixation seat has two stators, and two stators are respectively adjacent to two relative inwalls of accommodation space, and when permanent magnet passed through accommodation space, permanent magnet was just between the induction coil of two stators.

In the aforementioned disc, wantonly two permanent magnets adjacent have two opposite magnetic pole distributions.

Aforementioned bicycle frame is a crotch.

The beneficial effects of the utility model are: it can produce electric power when the user drives bicycle, and then provides electric power to light fixture or the miscellaneous equipment that is connected on the bicycle generating set.

The number in the figure explanation:

10 frameworks, 11 holders

12 rotating shafts, 131 axle sleeves

13 wheels, 15 stators

151 bobbins, 152 induction coils

50 discs, 55 permanent magnets

S, N magnetic pole

Embodiment

Please refer to Fig. 1 to Fig. 5, the utility model bicycle generating set is arranged on the disc 50 on the axle sleeve 131 that holder 11 and on the bicycle frame 10 is arranged on cycle wheel 13, and wherein this framework 10 is front forked frame, rear crotch or near the backbone structure at rotating shaft 12 positions.

Be formed with an accommodation space 111 on this holder 11, this accommodation space 111 has two relative walls, is provided with at least one stator at the wall of holder 11, and each stator 15 has a bobbin 151 and and is wrapped in induction coil 152 on the bobbin 151.In addition, induction coil 152 connects at least one accumulate element carrying out accumulate, and further connects mobile phone or other personal electric or communication device, so that provide electric power to these electronic installations.

This disc 50 is fixed on the axle sleeve 131 of wheel 13, and a part is positioned at accommodation space 111, on disc 50, be embedded with several permanent magnets 55 as rotor, permanent magnet 55 is arranged lopping in the concentric circles mode, when each permanent magnet 55 enters accommodation space 111, towards two relative walls of accommodation space 111, permanent magnet 55 turnover accommodation spaces 111 seasonal induction coils 152 produce induced current to two magnetic pole S, the N of permanent magnet 55 respectively.In the disc 50, wantonly two permanent magnets adjacent 55 have two opposite magnetic pole S, the N distribution produces sufficient induced current so that make induction coil 152 be subjected to the quick variation of magnetic flux.

In preferred embodiment, holder 11 has the two relative inwalls that two stators, 15, two stators 15 are respectively adjacent to accommodation space 111, and when permanent magnet 55 passed through accommodation space 111, permanent magnet 55 was just between the induction coil 152 of two stators 15.

By above-mentioned technological means, the relative motion of induction coil 152 and permanent magnet 55, cause the magnetic flux change on the induction coil 152, thereby induction coil 152 can produce induced current, therefore, bicycle generating set promptly is that the kinetic energy with permanent magnet 55 is converted to electric energy, is connected to electronic installations such as LED when induction coil 152, can power to electronic installation.
