Description

A kind of power-aid bicycle chain wheel component of detectable torque
Technical field
The utility model is related to electric boosted bicycle technical fields, more particularly, to a kind of power-assisted foot of detectable torque Treadmill chain wheel component can accurately sense output torque of the power-aid bicycle when manpower is ridden.
Background technology
Currently, being equipped with the electric bicycle of accumulator, wheel hub motor because its is laborsaving, the advantages that facilitating obtains at home It is universal, however there are the following problems existing electric bicycle:Although electric bicycle remains footrest, so that cyclist uses Manpower is ridden, but the footrest and wheel hub motor as power source can be separately controlled, that is to say, that cyclist can be existed by setting Electric switch on vehicle handle directly controls the rotating speed of wheel hub motor, advances so as to fully rely on electrically driven vehicle.In this way, When electric riding state, due to cyclist it is difficult to control the size of electric switch, to which electric power auxiliary drive and foot can not be made to step on drive It is dynamic good fit, it causes that pure driven by power pattern can only be used, and foot-operated ride only can just adopt when accumulator electric-quantity exhausts With.Although the driving mode has fast, effortlessly benefit, easy tos produce and drive over the speed limit, in turn result in the uneasiness ridden Entirely.In addition, the manpower that it also cannot be satisfied part population is ridden with the requirement taken exercises.That is, it is existing it is electronic from Driving is extremely difficult to based on manpower, the effect of electric power auxiliary.
For this purpose, people have invented electric assisted bicycle, the essential structure of electric assisted bicycle and operation principle and electricity Dynamic bicycle is similar, is also by accumulator drive hub motor, to drive vehicle to travel, still, control wheel hub is electric Machine rotating speed is controlled by the signal that corresponding sensor is sensed, when controller receives the speed of the footrest of sensor output When the signals such as the state of degree, torque or vehicle, you can automatically control the working condition and output torque of wheel hub motor.Also It is to say, cyclist cannot achieve pure driven by power in the state of not using foot-operated ride, and electric drive is only used for auxiliary and drives It is dynamic, so as to effectively limit the travel speed of vehicle, while it can realize labour-saving purpose.
For example, disclosed in Chinese patent literature " a kind of Moped Scooter control method and system ", publication No. is CN106828758A, this method are sensed electronic using the gait of march of velocity sensor sensing Moped Scooter using level meter The transport condition of vehicle using motor, when Moped Scooter starts to ride, gait of march is more than zero, at this time if Moped Scooter When transport condition is horizontal transport condition, then the torsion for acting on footrest by manpower merely drives Moped Scooter, and records The velocity of rotation or torque value of vehicle footrest under horizontal transport condition;If the transport condition of Moped Scooter is up-hill journey When state, then start drive motor and rotate forward, auxiliary power is formed, to make footrest reach the rotation under horizontal transport condition Speed or torque value.That is, vehicle is when going up a slope, cyclist's foot tramples the traveling of the torque value that foot is exported and vehicle Speed and level are consistent when driving;If the transport condition of Moped Scooter is descent run state, vehicle is relied on Inertia reversely drive drive motor rotation power generation, so as to be mobile power charging.
Although such Moped Scooter can automatically control the driving mode of vehicle according to actual travel state, it is still There are following defects:First, electric boosted, power-assisted effect unobvious are cannot achieve when in horizontal transport condition when vehicle. Secondly, what such vehicle using motor controlled when electric boosted is not the size for the torque that motor exports, but the traveling of vehicle is fast Degree, although being conducive to simplify control mode, output torque excessive problem when be easy to causeing electric boosted, in particular, When very big or vehicle the load of the gradient of upward slope is larger, the overlond running of accumulator and wheel hub motor can be caused, to tight Ghost image rings its service life.
For this purpose, someone is mounted with the sensing of detectable chain tension in the tensioning side of the driving chain of moped Device, the advancing side of driving chain is by sensor bending, and when manpower is ridden, driving chain is tensioned, and sensor can be experienced The tensile force of driving chain and export an electric signal.And when needing to go up a slope or quickly ride, the output that manpower is ridden is turned round Square is bigger, and the tensile force of driving chain is bigger, and correspondingly the electric signal of sensor output is bigger.In this way, control wheel hub motor work The controller of work can correspondingly control the output torque of wheel hub motor according to the electric signal that sensor exports, and manpower is made to ride Output torque and the output torque of wheel hub motor match, and are just realizing that manpower is the effect of main electric power auxiliary very.
However there are following defects for sensors with auxiliary electrode:What is just really experienced due to sensor is that driving chain is extensive in bending part Multiple straight active force, that is to say, that sensor was sensed is not the tensile force of driving chain, therefore, final to cycle Linear relationship can not be formed between the electric signal that the output torque and sensor of people is exported.Correspondingly, wheel hub motor work is controlled The controller of work needs first to carry out the electric signal of the sensor received complicated calculating, and it is defeated then could to control wheel hub motor Go out the output torque ridden and matched with manpower, both caused the complexity of control, while being unfavorable for realizing electric power auxiliary output torque Match with the torque that manpower is ridden.
Utility model content
Purpose of the utility model is to solve existing using Moped Scooter, and to be difficult to the torque exported according to manpower big Small the problem of accurately controlling electric boosted output torque, provides a kind of power-aid bicycle chain wheel component of detectable torque, The output torque that manpower is ridden can be accurately detected, the torque that electric boosted output torque is exported with manpower is made to match, Ensure that cyclist can easily control the riding speed of vehicle according to the subjective desire of oneself, it is prominent to occur speed when avoiding riding Become.
