Description
Technical field
The present invention relates to technical field of bicycles more particularly to the connection structures of a kind of sensor and moped.
Background technique
Electric assisted bicycle usually steps on bicyclist to realize by torque sensor or torque measurement mode (TMM)
It steps on the real-time monitoring of strength and adjusts power output size in conjunction with cadence data to realize the mesh of power-assisted of riding
's.Traditional torque sensor is located in rotary part, and structure is excessively complicated, poor reliability, maintainable poor, mostly customizes
Structure lacks versatility, and since elastomer is under the action of single external force, be easy to cause stress release incomplete, cause
Sensor zero drift, and the gradient cannot be incuded, brake cannot be incuded, also lack effective machine overload protection measure.
There are mainly two types of the means for carrying out pedal force monitoring using torque measurement mode (TMM) currently on the market.One is
Rear axle hook approach sensor, another is that derrick type five leads to mode.The major defect of rear axle hook approach sensor is power
Square measurement is not accurate and serious by external interference, and sensor is built in the metal of Chain stay and Seat stay junction by this mode

It is not in stable state, in actually riding, due to the limitation of road conditions and various conditions of riding, chain can not Complete Bind
Five logical activities, five is logical in random swing state, causes to occur frequently to hit with pressure sensor, does not only result in and ride
It is poor to experience, and also results in the considerable degree of damage of pressure sensor or reduced lifespan；
Sensor can only induction pressure, pulling force cannot be incuded, so descending cannot be incuded, brake can not be incuded；
Sensor only receives uniaxial pressure, causes elastomer stress release incomplete, so as to cause serious sensor zero
Point drift phenomenon, actually all to there is a degree of null offset existing for the sensor of most of mopeds currently on the market
As, therefore starting requires to carry out zero point alignment every time, experiences not good enough；
The five-way structure of monoblock type is complicated, and processing technology is complicated, and installation difficulty is high, at high cost；
Five logical sunpenders usually require with respect to the horizontal plane can just obtain at some angle (such as 90 degree) under whole vehicle state
Optimal power-assisted effect, but if vehicle frame processing mismachining tolerance or front fork occurs and wheel packet size has occurred variation and will lead to this
The variation of angle will be unable to through simple mounting and adjusting to reach the function that the predetermined angle realizes anticipation；
Pressure sensor acceptable limiting pressure is limited, generally can not be more than the 50% of transducer range, be simultaneously
Guarantee measurement accuracy, the range of sensor should not also select excessive, however the five logical pressure that sensor is subject to are decided by ride
The weight and strength and range of passerby is very wide in range, therefore usually under technical conditions, in order to realize higher precision, pressure
Sensor has very big overload risk but to lack necessary safeguard measure, currently on the market the sensing of most moped
