Description
Technical field
The utility model belongs to sensor technical field, particularly relates to a kind of bicycle with mixed drive power chain wheel formula moment sensing apparatus and controller system.
Background technology
Battery-driven car domestic is at present mainly based on pure electric vehicle, and bicyclist does not need firmly.This car has restriction of strictly setting out on a journey abroad, in countries such as Japan, European Union, pure Electrical Bicycle is classified as mobile management, just comparatively popular in China.And electric assisted bicycle is a kind of environmental type vehicle, be again one body-building apparatus very easily, comparatively popular abroad.Its principle is, by a torque sensor, the size of people's pedal force is passed to controller, and controller controls motor and exports the moment-assistant of corresponding size, and the moment of output is directly proportional to manpower, and manpower is larger, and power-assisted is larger, do not add manpower then motor do not turn.Therefore can the assistant sensor of the pedal force of perception in time size be the emphasis that people study.
Develop various torque sensor for this reason both at home and abroad and carry out the size that perception judges whether to need to provide power-assisted and export power-assisted, when such as judging to ride pedal force size, step on the conditions such as frequency.Mode main at present has following a few class:
1, simple and easy strain-ga(u)ge transducer: this sensor uses strain-gauge or spring etc. to carry out the size of pedal force when perception bicyclist rides, but it is larger by factor of natural environment (temperature, muddy water, dust etc.) impact, the misoperation that particularly road bumps causes is difficult to overcome, machine structural parts processed complex simultaneously, tooling cost is high, easy generation metal fatigue and wearing and tearing, the life-span is short.

3, hall speed sensor: the program uses alnico magnets and Hall element, the frequency that Hall element exports to controller impulse singla is directly proportional to the speed that bicyclist rides, because the change of foot-operated speed and the change of pedal moment have correlativity, to a certain degree can reflect the change of pedal moment, but tradition generally arranges 5-6 magnetic pole when using, interval amplitude is larger, only have when being positioned at the alnico magnets on magnet steel dish by hall sensor, turn signal could be caught by hall sensor, so just cause hall sensor can not sense magnet in foot-operated moment, therefore existing induction mode has certain delay in time, change can not be responded in time.
4, light electricity velocity sensor: the circular grating of ingehious design can be accomplished very intensive, simulation moment and the effect exporting corresponding power-assisted are compared hall speed sensor and are wanted naturally a lot, although cost is low, static current of lcd is little, without absorbing iron contamination effect, but it is as discrete product, need during use to coordinate controller to be arranged on vehicle body together, volume is larger.
5, built-in torque sensor motor: by embedding sensor senses moment variations in motor, makes motor directly feed back the size of pedal moment, and this mode electric machine structure is complicated, and expensive, electrical machmary maintenance difficulty is large.
Therefore, existing sensor Problems existing is not that the power-assisted experience realized is poor, and be exactly complex structure, installation volume is large, and expensive, functional reliability is poor, is difficult to extensive use; In addition, existing controller for electric vehicle and sensor are generally two parts separately, and the bulky problem of ubiquity, installs very ugly onboard, and are exposed to and need periodical maintenance outward, are difficult to reach brief effect attractive in appearance.
