Abstract
The utility model relates to an electric bicycle controller. The utility model comprises a controlling circuit of a circuit board arranged in a box body, a speed sensor connected with the controlling circuit and a torque sensor. The utility model is characterized in that the detecting head of the speed sensor is arranged on a fixing frame of the rear wheel, and the detecting head of the torque sensor is arranged on the rotating axle of a stepping mechanism; a bicycle battery is connected with a motor and the controlling circuit. Therefore, a controller having human imitating memory function is formed, the controller can imitate the human thinking method to memorize the control requirement, the data of the control requirement is stored in a storing device in advance, the address of the storing device can be obtained through the output of two A/D converters respectively connected with the speed sensor and the torque sensor, and various control output quantity can be obtained from various addresses to control the force application state of the motor. During the running process, the rider feels easy and comfortable, the riding up the slope is as easy as the riding on the flat ground, and the utility model saves labor and electricity.
Description
Technical field
The utility model relates to a kind of electric assisted bicycle controller.
Technical background
Because Electrical Bicycle is power with the storage battery, pass through wheel driving motor, all or partly replacing manpower to drive travels, not only laborsaving, comfortable, and free from environmental pollution, so, late 1990s the Electrical Bicycle manufacture developed rapidly, the quality of product improves constantly, and the function of product is also further improved and strengthened.General Electrical Bicycle, its design plan are when the people does not want to scrunch, and replace manpower to drive by electrical motor fully and travel, and the size of the output torque of electrical motor is not controlled, and cause power wastage.In order to reduce unnecessary power consumption, the device of control motor output torque size the travel conditions according to Electrical Bicycle appearred.It is that ZL98207982, name are called " the laborsaving work-saving device of Moped Scooter " that Patent Office of the People's Republic of China announced the patent No. on November 10th, 1999.This device is received stretcher and is trampled tach signal and rear wheel tach signal by a controller, and the output torque size with the control motor reaches laborsaving, purpose of power saving.But only trample the output torque size that rotating speed and rear wheel rotating speed come the control motor, can't reach fully and drive comfortable effect, and its control system is also comparatively complicated according to stretcher.
Summary of the invention
Goal of the invention of the present utility model provides a kind of electric assisted bicycle controller, it can be according to rider's the rotating speed that scrunches moment and trailing wheel, the size of control assist torque output, realize electric boostedly cooperating with manpower, it is easily comfortable that the rider feels, it is as though walking upon flat ground to go up a slope, both laborsaving, power saving again.
Electric assisted bicycle controller described in the utility model, comprise the control circuit on the circuit card that is contained in the box body, with control circuit bonded assembly speed sensor and torque sensor, the gauge head that it is characterized in that speed sensor is located on the fixed support of trailing wheel, and the gauge head of torque sensor is located on the turning cylinder that scrunches mechanism; The storage battery of bicycle is connected with control circuit with electrical motor.Constitute a controller thus with apery memory function, it can touch the mode of thinking memory control requirement down of apery, the data that control is required deposit in the memory in advance, by obtain the address of memory respectively with the output of speed sensor and two A/D converters of torque sensor bonded assembly, obtain different control outpuies by different addresses, with the afterburning situation at control motor.
Described electric assisted bicycle controller, the control circuit on its circuit card are by eprom memory, with two A/D converters of memory device bonded assembly, with memory device bonded assembly D/A converter, form with D/A converter bonded assembly signal conversion circuit, with signal conversion circuit bonded assembly power DC-DC changer; An A/D converter of control circuit is connected with speed sensor, another A/D converter is connected with torque sensor, storage battery is connected with the power DC-DC changer of control circuit, the mouth of power DC-DC changer is connected with electrical motor, electrical motor cooperates with the rotating shaft of Electrical Bicycle trailing wheel, drives the trailing wheel rotation.After on the Electrical Bicycle this controller being installed, rider and motor can participate in reinforcing in the driving process; The rider firmly acts on trailing wheel by scrunching mechanism, detect simultaneously by the force-bearing situation of torque sensor to the turning cylinder that scrunches mechanism, by speed sensor the trailing wheel velocity magnitude is detected, and signal passed to after control circuit handles, it is corresponding electric boosted or do not provide corresponding electric boosted that the output signal control motor provides, with firmly cooperating of rider, realize intelligent power-assisted.On level road, travel or speed of a motor vehicle when moderate, the power that the rider uses from big to small, rear wheel rotation speed from low to high, general in 15-24 kilometer/hour scope, electrical motor then provides reduce gradually electric boosted.Downhill running or when running at high speed, the rear wheel rotation speed height generally surpasses 24 kilometers/hour, the rider not firmly or firmly less, it is electric boosted that electrical motor does not then provide.Go up a slope or when beginning to ride, the rider's is firmly bigger, rear wheel rotation speed is lower, and generally below 15 kilometers/hour, it is equal-sized electric boosted with manpower that electrical motor provides, and makes the rider feel easily comfortable, and it is as though walking upon flat ground to go up a slope.In whole driving process, both laborsaving, power saving again.
