Electrical Bicycle has become a kind of general vehicle with its safety, characteristics such as environmental pollution is few, use cost is low.Electrical Bicycle can be divided into pure Electrical Bicycle and booster type electric bicycle by its mode.
Pure Electrical Bicycle is comparatively popular in China at present, it controls motor speed with turning handle, increased control device than riding Regular Bicycle, but also comprised certain safety hazard, used battery when riding always, power consumption is more, battery charge mileages of continuation once is short, thereby charging times is frequent, and battery is short service life, has increased user's the cost of riding.
The booster type electric bicycle is comparatively popular abroad, and this cycling mode and bicycle are just the same, people's electricity muck in, and consumption of current is less, and battery charge mileages of continuation once is long, thereby battery age can be prolonged more than one times.Therefore, the booster type electric bicycle is the developing direction of Electrical Bicycle in future.
The key problem in technology of booster type electric bicycle is assistant sensor.At present, assistant sensor mostly is the torque type sensor, measures and rides the moment that produces when the people rides, convert aanalogvoltage to, the voltage that instead of pure Electrical Bicycle handle is sent after amplification or other processing is given controller, and the bicycle power-assisted is given in the rotation of control motor.The assistant sensor common configuration complexity of this mode, cost is higher; In addition, use parts such as spring, contact, friction wheel, gear more than the existing torque type sensor, be easy to wearing and tearing, the stability that very difficult assurance works long hours.
For solving the above-mentioned defective of the sensor existence that has Electrical Bicycle now, Chinese patent notification number CN2640915Y discloses a kind of " time type electric assisted bicycle sensor ", this time type electric assisted bicycle sensor has a Moving plate and a price fixing, price fixing is provided with Hall element, and Moving plate is provided with permanent-magnet steel.
The magnet steel of this time type electric assisted bicycle sensor is fixed on the rotating circular disk (Moving plate) that rotates with axis, and Hall element is fixed on not on the disk (price fixing) that changes with axis.
As Hall element and permanent-magnet steel alternative, price fixing is provided with also can be provided with light source and light receiving element, and Moving plate is provided with a grating dish.
This time type electric assisted bicycle sensor has following characteristics: 1, simple in structure, make easily, have only a Moving plate and a price fixing.2, with low cost.3, sensing accurately, reliably.
Use this time type electric assisted bicycle sensor of Hall element and permanent-magnet steel, its accuracy of detection is low, and after long-time the use, the magnet steel on the Moving plate easily demagnetizes, easily comes off, and more can influence accuracy of detection and accuracy.
Use this time type electric assisted bicycle sensor of light source and light receiving element,, also can influence sensor detection accuracy though its accuracy of detection height after long-time the use, enters dust easily between Moving plate and the price fixing.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of detection accuracy good electric assisted bicycle sensor.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of electric assisted bicycle sensor, it comprise the Moving plate that rotates with axis, with the fixing price fixing of vehicle body, price fixing is provided with light source and light receiving element, Moving plate is provided with grating, grating is arranged between light source and the light receiving element; Price fixing comprises annular slab, and Moving plate comprises annular slab; Be provided with tubular madial wall and tubular lateral wall between two annular slabs.
In the such scheme, tubular madial wall and tubular lateral wall are arranged on the annular slab of price fixing.
In the such scheme, Moving plate is provided with outside connecting wall, and tubular lateral wall top has the groove that inserts for outside connecting wall.
In the such scheme, Moving plate is provided with inboard connecting wall, and the top of tubular madial wall and the top of inboard connecting wall are respectively equipped with the barb that cooperatively interacts.
In the such scheme, light source on the price fixing and light receiving element are two pairs.
Disclosed with Chinese patent notification number CN2640915Y " time type electric assisted bicycle sensor " compared, and the utility model sensor has the following advantages:
1, price fixing comprises annular slab, and Moving plate comprises annular slab, is provided with tubular madial wall and tubular lateral wall between two annular slabs, and axis passes from the tubular madial wall.Tubular madial wall between two annular slabs and tubular lateral wall can form sealing between two annular slabs, prevent that dust from entering sensor, improved sensor detection accuracy.
2, tubular madial wall and tubular lateral wall are arranged on the annular slab of price fixing, make price fixing become a ring shield, and ring shield covers on the Moving plate, makes the better tightness of whole sensor.
3, Moving plate is provided with outside connecting wall, and tubular lateral wall top has the groove that inserts for outside connecting wall, helps improving the globality of sensor.
4, Moving plate is provided with inboard connecting wall, and the top of tubular madial wall and the top of inboard connecting wall are respectively equipped with the barb that cooperatively interacts, and not only can make the better tightness of sensor, and price fixing and Moving plate are linked together.
