Abstract

The utility model relates to a microgenerator, particularly to a microgenerator applied to toy cars, small-sized fans, and toy boats. The microgenerator comprises a coil and a generator product formed by a stator and a rotor which are fixed inside a housing, wherein the stator does not need to be fixed with screws, can be directly dismantled, and a rear cover of the stator can also be directly detached. In use, an external force acts an iron core of the rotor, thereby driving a rotor bearing to rotate synchronously, enables the coil to be subjected to stable magnetic field changes which are strong enough in intensity, thus providing kinetic energy for products, such as toy cars and toy boats. The microgenerator has the advantages of simple technology, convenient production, small size and stable power generation efficiency, can effectively solve the problems of complex structure, complicated manufacture technologies, large size, and high cost of traditional generators, and can satisfy the requirement on generator equipment in daily life and in the production field.

Description

A kind of microgenerator

Technical field

The utility model relates to the microgenerator technical field, particularly is applied to toy car, small-sized fans, the microgenerator of toy boat.

Background technology

Electric energy is one of topmost energy of modern society.Generator is the mechanical device that the energy conversion of other form is become electric energy.It can be with current, air-flow, and the Conversion of Energy that fuel combustion or nuclear fission produce is electric energy.Generator is in industrial and agricultural production, and national defence has been widely used in science and technology and the daily life.Because the conventional electric generators complex structure, manufacture craft is loaded down with trivial details, and required parts are many, and cost of manufacture is higher; And volume ratio is huger, uses inconvenience, can't adapt in daily life and the production field consumer to the demand of gen-set.

Summary of the invention

The utility model embodiment problem to be solved is for above-mentioned the deficiencies in the prior art, and a kind of simple in structure, convenient for production, the volume scale is adjustable and generating efficiency is stable microgenerator product is provided.

Above-mentioned microgenerator is to comprise coil and be fixed in the generator product that forms in the housing by stator and rotor, and it is comprised of coil, stator, stator bonnet, rotor bearing, rotor core, wire and housing.Wherein, described stator adopts ABS plastic (acrylonitrile-butadiene-styrene (ABS) plastics) to be processed into, and this stator need not be fixed through screw lock, can directly dismantle, and its bonnet and stator integral body are carried out clamping, and bonnet also can directly be taken apart; Described rotor has rotor core and rotor bearing, and what this rotor bearing adopted is the fine copper bearing, and described rotor bearing is comprised of multi-disc N, S utmost point neodymium iron boron magnetic body alternately; Described coil winding is at described stator both sides inwall, and respectively leave hollow convex interface in the stator both sides, the two poles of the earth of described coil are connected with wire by this convex interface, this coil adopts the fine copper enamelled wire, adopt the mode of series connection, at stator one group of coil is arranged each side, middle design separates, and the adjacent magnets magnetic pole under the coil parcel is opposite; Described coil winding is on stator, and stator is connected with rotor, and places in the housing, by encapsulating fixing at housing afterbody pouring resin material.

When using according to said structure, the iron core of rotor is subject to external force and rotates, can take the rotor bearing that contains magnet that is fixed on the iron core to rotates synchronously, further, thereby just make coil be subject to a stable and changes of magnetic field that intensity is enough strong and produce electric power, the two poles of the earth of wire link to each other with stator by the convex interface, can directly realize the power supply to electric equipment products.This coil adopts the fine copper enamelled wire, then can avoid the loss of electric weight, can not cause the unsettled problem of electric weight when generating electricity, thereby has improved the operating efficiency of generator.

So, the utility model has the advantage of that structure and manufacture craft are simple, cost of manufacture reduces; Because adopting brushless electric machine, can not produce that coil is easy to wear, the problem of carbon distribution, thereby improve the life-span of generator; The utility model quite is suitable for use in the various generation modes (such as wind-force, waterpower, solar energy or manpower etc.) as power supply.The design's overall structure is very ingenious, and the volume of generator can be dwindled greatly, can satisfy in the every field consumer to the demand of generator product.
