Abstract

The present invention relates to a driving rim motor. A driving rim motor device is contained in the containing space of a wheel hub cap. When a circuit is switched on, an armature of the driving rim motor device is switched on and is cut by magnetic lines of a field magnet. Thus, a drive shaft is driven to rotate by the armature, and the wheel hub cap is rotated by the rotating drive shaft. An insulating base which comprises an electric brush and a spring is arranged in the driving rim motor device. The present invention is characterized in that the electric brush in the insulating base can vertically contact with an annular commutator plate surface of a commutator fitted over the drive shaft under the pressure of the spring.

Description

Driving-felly motor

Technical field

The invention provides a kind of driving-felly motor, especially finger is applied to the driving-felly motor on the wheel, and circuit board is to be contained in the shell of driving-felly motor device, and the centre bore of circuit board is the ring-type commutator segment outside around commutator, and make brush in the insulating base of control circuit board top see through the extruding of spring and support to be affixed on the commutator segment, to be combined into one with control cabinet and the motor that reaches the formula circuit.

Background technology

Press, environmental protection and air cleaning are done one's utmost to advocate by society now, and make vehicle all towards taking power start as the main direction of its research and development, yet, known electric bicycle is because of existing dynamic output size wayward, electric power can't reach shortcomings such as volume is excessive lastingly, be that on October 28th, 1 proposed novel patent application with electric wheel ring motor and solves the problems referred to above in Taiwan with the applicant, and this case had been announced already in the 2388 No. one on record checking, and can consult the 6th, shown in seven figure, it mainly approaches the folded also suitable coil of winding thereon of silicon steel sheet to constitute armature by the platypelloid type of multilayer, and become one with the center that the platypelloid type commutator is embedded at armature, can shorten width, do not take up space, and have practicality, in the wheel center axle, be provided with passage and also in position punching to wear power line; Motor is connected with a formula control circuit, and this formula control circuit is connected with power supply and infrared transmitting receiver respectively; This kind device construction can effectively be reduced motor width and volume, does not need planetary gear can produce enough torsion; And formula controls electric network and can calculate the signal that is received and come finding speed with the control electric power output voltage, arrives constant speed when above at wheel velocity, and power supply can CD-ROM drive motor, can avoid the danger that is taken place because of false touch voltage sudden startup; Overall volume of the present invention is little, has safety, economy, is easy to practical good efficacy; Learn by above-mentioned, though preceding case has splendid effect and smaller volume, because of the control cabinet of CD-ROM drive motor and formula control circuit for being separate design, after using via permanent consumption is popular, still having following several somes shortcomings can be for improvement:

1. CD-ROM drive motor commonly used is a separate design with circuit box, promptly need make two ccontaining utensils the two is accommodated the location, and two ccontaining utensils needs again assemble on bicycle, so setting, processing and the manufacturing cost used always are all higher.

2. the common circuit case is easier to produce damaged in collision for being fixed on the car body, more because of with driving-felly motor be released state, be not easy in the installing and make, and this kind separate type design also influences the car body outward appearance easily.

Be with, for the foregoing reasons, the applicant i.e. thinking as how preferable structural design separately, makes this kind driving-felly motor can stablize more and effectively be used on the electronic car body and use.

Therefore, the applicant is because above-mentioned deficiency is via assessing in many ways and considering, utilize the research and development experience for many years of engaging in the sector again, after constantly studying and revise, the side is based on preferable structural design and increase stability, and the beginning is designed the creation birth of this kind driving-felly motor.

Summary of the invention

Main purpose of the present invention is to be provided with in the shell of driving-felly motor device two groups or the two groups of above brushes and the insulating base of spring, and the brush in this insulating base is for can vertically supporting the ring-type speed flow surface that is affixed on commutator sheathed on the power transmission shaft by the extruding of spring.

Secondary objective of the present invention is that the insulating base that will have brush and spring is fixed on the circuit board, and make the ring-type commutator segment outside of the centre bore of circuit board around commutator, brush in the insulating base of its circuit board upper fixed is affixed on the commutator segment for supporting by the extruding of spring, in order to do controlling organization and the motor about circuit can being combined into one.And circuit board is for directly to be contained in the shell of driving-felly motor device.

Another object of the present invention, its circuit board is can be further combined with the electronic component that control circuit is arranged, and can form the completed power rim motor module of a tool formula control circuit, in order to simplify assembly program, to reduce cost and promote attractive in appearance the going up of having installed the car body appearance and use.

Be equipped with the driving-felly motor device in the accommodation space of wheel enclosing cover of the present invention, when turning circuit, can make the armature energising of driving-felly motor device, and by the magnetic force line cutting of field magnet, rotate and make armature drive power transmission shaft, by the power transmission shaft that rotates the wheel enclosing cover is rotated again thereupon; It is characterized in that: be provided with two groups or two groups of above brush and spring insulating bases in the shell of this driving-felly motor device, the brush in this insulating base is for can vertically supporting the ring-type commutator segment surface that is affixed on commutator sheathed on the power transmission shaft by the extruding of spring.

Overall volume of the present invention is little, has safety, economy, is easy to practical good efficacy.Also can stablize more and effectively be used on the electronic car body and use.It is simple in structure, compactness, and ease of assembly, maintenance are suitable for applying.
