Abstract
The utility model relates to a generator for charging a storage battery of a driving aid bicycle, comprising a rotor component composed of a rotor core, a magnetic steel insert, a rotor shaft and a rotor casing as well as a stator component composed of a stator core, a stator winding and a supporting piece. The rotor component is driven to rotate through the input power of the output shaft of a mobility aid. The rotation of the magnetic steel leads to the flux variation of the stator core, generates electromotive force in the stator winding and outputs alternating current which is converted into direct current through a rectifier. Accordingly, the continuous charging of the storage battery is implemented, which overcomes the trouble brought by the storage battery requiring periodic charging, provides permanent power supply for electrical equipment, such as turn lights, etc. installed on the bicycle and ensures driving safety.
Description
The utility model relates to the electrical generator fields with magnet steel, particularly with the supporting power-supply device of bicycle mobility aid.
Bicycle is people's the main vehicles, in order to alleviate the degree of fatigue of rider, improve driving speed, equipped mobility aid is more and more on bicycle, because the installation of mobility aid, cause that the speed of a motor vehicle accelerates greatly,, be preferably in direction indicator lamp is installed on the bicycle for avoiding the generation of traffic accident, in order to make direction indicator lamp obtain nonvolatil power supply, storage battery must be installed, yet storage battery self has only energy storage function, there is no electricity generate function, therefore, must regularly charge, just can keep the power supply supply of electric equipments such as direction indicator lamp, this brings very burden to the user.
The purpose of this utility model overcomes the deficiencies in the prior art exactly, provides a kind of aiding bicycle storage battery charging generator that can make storage battery have automatic charge function to the public.
The purpose of this utility model is achieved by the following scheme, and it is by the rotary power of mobility aid output shaft, and the utilization electromagnetic induction principle produces induced current, realizes that storage battery charges automatically, and the power supply of bicycle electric equipment is provided.This generator comprises rotor part and stator component.Rotor part i.e. the magnet steel inserts of circumference uniform distribution even number on the surface of rotor core, and the armature spindle cast solid that is connected with engine output shaft, the rotor overcoat of close-fitting is housed on the outer surface of rotor, play and reinforce the magnet steel effect, make the magnet steel position not be subjected to the rotor high-speed rotation and the influence of the centrifugal action that produces.
With identical air gap circumference uniform distribution, stator core is fixed on the fixed head between 1-4 group stator component and the rotor part, and installs with the support sheet and to reinforce, and the adjacent stators winding links to each other with lead mutually.
Like this, form magnetic circuit, when rotor rotates, drive magnet steel and rotate by rotor, stator and air gap.Owing to select specific parameter for use, the stator core bipolar shoe of stator component just replaces the magnet steel area to change, in whole rotation round, cause the stator core flux change, thereby in stator winding, produce the electromotive force of continuous wave, the alternating current that sends is transformed into the direct current of continuous impulse by external rectifying device, realization is to the storage battery quick charge on the bicycle, thereby makes electric equipment such as direction indicator lamp obtain power supply.
The utility model and the supporting use of bicycle mobility aid by the output torque of mobility aid, make generator work, automatically to the storage battery charging, have overcome the defective that storage battery regularly charges in addition, guarantee that the power supply of direction indicator lamp is supplied with, for traffic safety provides reliable guarantee.
