Description

The CD-ROM drive motor structural improvement of electric motor car

Technical field:

The utility model relates to a kind of CD-ROM drive motor structure of electric motor car, relates in particular to the CD-ROM drive motor structure that a kind of its outputting torsion can be made the electric motor car of the innovation that height load switching is adjusted, electric power can be stored storage.

Background technology:

Advantages such as electric motor car is light owing to having, environmental protection develop into a kind of leisure walking-replacing tool of quite popularizing in recent years gradually.

General electric vehicle structure generally includes a car body front and back ends pivot group wheel, and described wheel links by a driving member and a CD-ROM drive motor, is assembled with storage battery on the car body simultaneously, is used to provide the CD-ROM drive motor required electric power; The common structure of described CD-ROM drive motor is by an enclosure interior one stator to be set, and constitutes by axle pivot group one rotor in the space center that motor-field that this stator forms is surrounded; But in actual use, there is following problems in the CD-ROM drive motor structure of above-mentioned electric motor car commonly used:

Outputting torsion that should CD-ROM drive motor commonly used is (being that the big more then speed of torsion is more little) that is inversely proportional to speed in a scope, therefore, when the road surface that electric motor car travels transfers the climbing situation to by the plane, the outputting torsion of this CD-ROM drive motor will obviously become and weaken and powerlessness occurs, and the driver also can't be adjusted.

In view of this, though there is later the people of the sector be engaged in to attempt utilizing the mode that installs second group of CD-ROM drive motor commonly used additional to solve this problem, though can provide bigger torsion in conjunction with the output strength of two groups of motors like this; But, also increased the weight of electric motor car significantly because having installed the motor of the same kenel of this group additional, more dwindled originally quite limited space, cause the problem that runs in the opposite direction with electric motor car " lightweight " development designer trends so on the contrary, and the problems such as significantly raising of the relative increase of electrisity consumption, manufacturing assembly cost, all reduced the feasibility of this structure, so this is not a kind of method of dealing with problems that suits practical economic benefit.

The utility model content:

The purpose of this utility model is to solve the problem that the existing CD-ROM drive motor structure torsion of using electric motor car always can't be adjusted raising, provide a kind of by also being provided with the CD-ROM drive motor structure that second rotor and this housing also are provided with the electric motor car of second stator on this axle, can do height load switching adjustment to reach torsion, significantly promote the purpose of CD-ROM drive motor outputting torsion.

For achieving the above object, the CD-ROM drive motor structure of the utility model electric motor car comprises a housing, a stator and a rotor; This stator is arranged at inner walls and surrounds the shape motor-field to form, and in aforementioned motor magnetic field central authorities, this axle end then extends to housing and forms drive end outward this rotor by an axle pivot group; Also be provided with second rotor on the axle of this rotor; This inner walls also is provided with second stator, and described second stator is relative with aforementioned second rotor-position; Also establish a controller in addition, described controller links the storage battery and a signal switch of this CD-ROM drive motor, electric motor car by circuit; One end of this second rotor is provided with rectifying device (as brush), and described rectifying device links by the storage battery of circuit and electric motor car.

Above-mentioned controller can be one to have the circuit board of controlled sequence chip.

Wherein, described CD-ROM drive motor is brush motor or brushless motor.

Compare with the CD-ROM drive motor structure of existing electric motor car, the CD-ROM drive motor Adjustable structure of the utility model electric motor car is whole to promote CD-ROM drive motor outputting torsion, the changeable adjustment of height load, and electric power can be stored to storage battery.
