Description
Technical field
The utility model belongs to the Electrical Bicycle annex, relates in particular to a kind of Electrical Bicycle chain-type torque sensor that utilizes chain tension to change the regulation and control current of electric.
Background technology
Electrical Bicycle is light with it, fast and deeply be subjected to customer's favor, obtains develop rapidly in China.The mode of riding of Electrical Bicycle is conventional to be the electrodynamic type velocity pick-up, promptly a velocity pick-up magnetic sheet is installed at the wheel disc axis place of Electrical Bicycle, be used for controlling the electric current of motor, the shortcoming of this device is when the condition of riding changes, when the bicyclist needed the motor horsepower output big painstakingly, power of motor output diminished on the contrary.The bicyclist is painstaking when for example going up a slope, and bicycle speed is low, and the motor horsepower output is little, and the bicyclist steps on and steps on soon during descending, the bicycle speed height, and the motor horsepower output is big, to bicyclist's danger close.Demand developing a kind of sensing and controlling device that can change the current of electric size in the industry urgently with the size of foot-operated power.
The utility model content
Main purpose of the present utility model is to overcome above-mentioned technological deficiency, and a kind of Electrical Bicycle chain-type torque sensor is provided, and can utilize chain tension to change the regulation and control current of electric.That is, the size conversion that will ride power through sensor becomes corresponding analog voltage signal, by the size of current of controller control motor.
For realizing that the technical scheme that the purpose of this utility model adopts is, a kind of Electrical Bicycle chain-type torque sensor, mainly contain controller and be installed on the lead of pegging graft with controller on the shell, it is characterized in that: the cycle chain below is equipped with torque sensor, torque sensor mainly contains the chain guide wheel, depression bar, flat thin magnet, magnet-sensitive element and shell, described chain guide wheel links with chain, the chain guide wheel is by bearing pin and depression bar one end pin joint, be provided with mandrel hole and affixed in the middle of the depression bar by mandrel and shell, the depression bar other end is connected with flat thin magnet, between flat thin magnet and mandrel, be equipped with elastic component, elastic component one end is connected with hanger on the depression bar, the elastic component other end withstands in the side wall of outer shell retaining groove, is connected with magnet-sensitive element with the flat thin magnet correspondence position on the shell end wall.
Described guide wheel also can be the bar shaped guide block, and the pin sleeve in its upper surface and the chain touches.
The mandrel hole of described depression bar can be located at its end by mandrel and shell pin joint, and flat thin magnet is fixed between mandrel and the guide wheel.
Described elastic component can be pressure spring.
Described guide wheel both sides are provided with anti-lost.
Described shell two side is provided with vibration pad.
The beneficial effects of the utility model are to utilize chain tension to change the regulation and control current of electric.That is, the size conversion of foot-operated power is become corresponding analog voltage signal, by the size of current of controller control motor.Reach riding speed and be directly proportional, accomplished that 1: 1 power-assisted rides, save electric energy, increase the mileage of riding with foot-operated power.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the preferred embodiment and the specific embodiment structure of the present utility model and principle of work are further specified.
Please refer to accompanying drawing, a kind of Electrical Bicycle chain-type torque sensor, cycle chain 1 below is equipped with torque sensor, torque sensor mainly contains sprocket-shaped guide wheel 3, depression bar 4, flat thin magnet 9, magnet-sensitive element 10 and shell 5, described sprocket-shaped guide wheel 3 links with cycle chain 1, sprocket-shaped guide wheel 3 is by bearing pin 12 and depression bar 4 one end pin joints, and the guide wheel both sides are provided with catch 2.The two side is provided with rubber vivroinsulator 11 in the described shell.Depression bar 4 middle parts are provided with mandrel hole 13 and affixed by mandrel 7 and shell 5, depression bar 4 other ends are connected with flat thin magnet 9, between flat thin magnet 9 and mandrel 7, be equipped with elastic component 8, elastic component 8 one ends are connected with hanger 16 on the depression bar 4, elastic component 8 other ends are loaded in the retaining groove 15 of shell 5 sidewalls, and described elastic component 8 can be pressure spring; Be connected with magnet-sensitive element 10 with flat thin magnet 9 correspondence positions on shell 5 end walls; Described guide wheel also can be the bar shaped guide block that links with chain, and the pin sleeve in its upper surface and the chain touches (not shown).The mandrel hole 13 of described depression bar 4 can be located at its end by mandrel with the shell pin joint, flat thin magnet 9 is fixed in (not shown) between mandrel 7 and the guide wheel 3.Its principle of work is: when the bicyclist pedals with energy car, foot-operated power increases, depress guide wheel 3 by chain 1, guide wheel 3 drives depression bar 4 and moves down, flat thin magnet 9 at depression bar 4 one ends produces relative displacement with magnet-sensitive element 10 (Hall unit UGN35031), magnet-sensitive element 10 converts displacement to voltage signal and inputs to Electrical Bicycle universal controller 14 by lead 6, and the electric current of motor is controlled.When foot-operated power increased, current of electric can increase, on the contrary current of electric reduce, realize that riding speed is directly proportional with foot-operated power, the power-assisted that reaches 1: 1 is ridden, and saves electric energy, the increase mileage of riding.
