Description
Technical field
The present invention relates to intelligence sensor, particularly a kind of intelligent sensor for electric boosting bicycle that utilizes the circular arc laminated spring.
Background technology
Electric bicycle has become a kind of general vehicles with its safety, characteristics such as environmental pollution is few, use cost is low.Electric bicycle can be divided into pure electric bicycle and booster type electric bicycle by its control mode.Pure electric bicycle is comparatively popular in China at present, and it controls motor speed with turning handle, compares to ride general bicycle and increased control device, but has also comprised certain unsafe factor; Use battery when riding, power consumption is more always, and battery charge mileages of continuation once is short, thereby charging times is frequent, causes the serviceable life of battery short, has increased user's the cost of riding.The booster type electric bicycle is comparatively popular abroad, this cycling mode and bicycle are just the same, manpower and electric power muck in, and power consumption is less, battery charge mileages of continuation once is long, thereby makes can prolong more than one times the serviceable life of accumulator.Therefore, the booster type electric bicycle is the developing direction of electric bicycle in future.
So-called booster type electric bicycle is a kind of electric bicycle, but this electric bicycle be not depend alone electric motor driven.When riding, have only when the people applies certain power, motor just applies power.If the people does not apply power, motor can not apply power yet.Motor applies that the size of power is relevant with the size that the people applies power, and the power that the people applies is big, and the power that motor applies is also big; Otherwise power is just little.The motor of this booster type electric bicycle only plays the effect of power-assisted, therefore is called electric assisted bicycle.In recent years, this electric assisted bicycle is all the fashion in American-European countries, is one of research topic of present bicycle trade hot topic.
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 electric 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.
Chinese patent publication number CN2432080 discloses a kind of electric motor intelligent sensor, it contains mount pad, is fixed with Hall element on the mount pad, and hinged V-arrangement pickup arm, two openends of pickup arm are fixing magnet steel respectively, is connected with hinged follower at lever one end by leverage.During assembling, mount pad is fixed on the vehicle frame, Hall element is between two openends of V-arrangement pickup arm, and follower contacts with the electric motor car driving-chain.Because the structure of this device is bigger, must occupy than large space, therefore be unfavorable on electric assisted bicycle, using.

Embodiment
Specifically introduce a preferred embodiment of the present invention below in conjunction with accompanying drawing 1～3.
Referring to Fig. 1 and Fig. 2, the present invention is a kind of intelligent sensor for electric boosting bicycle, it is installed between the axis 1 and sprocket wheel 4 of electric assisted bicycle, mainly is made up of a butterfly flat board 2, a circular arc laminated spring 3, a magnet steel 5, a Hall element 6 and a brush 7.
Dull and stereotyped 2 rigid enclosure of butterfly be connected to axis 1 around, the plane of butterfly flat board 2 and axis 1 are perpendicular.
Referring to Fig. 3, the two ends of circular arc laminated spring 3 are equipped with a pivoted hole, and two pivoted holes are put relatively.One end A of circular arc laminated spring 3 connects with butterfly dull and stereotyped 2 by a pivoted hole, and the other end B of circular arc laminated spring 3 connects with sprocket wheel 4 by another pivoted hole.Circular arc laminated spring 3 bounces up or shrinks along the circular arc direction.
Two contacts of brush 7 are respectively near magnet steel 5 and Hall element 6.Brush 7 connects with the motor of electric assisted bicycle by circuit.
Circular arc laminated spring (3) is arranged between butterfly flat board (2) and the sprocket wheel (4).Circular arc laminated spring 3, butterfly dull and stereotyped 2 and sprocket wheel 4 these threes' plane is parallel to each other, and has formed the facade of three vertical directions.Such three-tier architecture has only increased a little size at the axis of original bicycle to the thickness of sprocket wheel, formed a kind of simple, light structure of the present invention, and this structure can not influence the normal function of electric assisted bicycle.
Circular arc laminated spring 3 is around being located on the axis 1.Circular arc laminated spring 3 is determined the deflection of circular arc laminated spring 3 and the size of foot-operated power with the relative displacement of measuring 6 of magnet steel 5 and Hall elements, and is translated into electric signal as the sensor of moment, controls the output power of motor by brush 7.
The principle of work of intelligent sensor for electric boosting bicycle of the present invention is as follows:
The axis and the sprocket wheel of ordinary bicycle are fixedly connected, and therefore being in operation, they together rotate.And in the present invention, take into axis and sprocket wheel apart two parts, make the axis 1 and 2 vertical connections of butterfly flat board of bicycle, butterfly dull and stereotyped 2 connects with an end A of circular arc laminated spring 3, the other end B of circular arc laminated spring 3 connects with sprocket wheel 4, like this, the axis of ordinary bicycle and the rigid attachment between the sprocket wheel just become the resilient connection by circular arc laminated spring 3 of the present invention.When riding, bicycle middle shaft must could drive sprocket wheel 4 by circular arc laminated spring 3 and rotate.As everyone knows, can produce distortion when spring stress, so when the people rode, circular arc laminated spring 3 can distortion, the size of its deflection applies power by bike time the with the people size is directly proportional.It is big to apply power, and deflection is just big, otherwise deflection is just little.The deflection of circular arc laminated spring 3 is exactly butterfly dull and stereotyped 2 and sprocket wheel 4 and the relative displacement at laminated spring interface A, B place, because magnet steel 5 is installed on the sprocket wheel 4, Hall element 6 is installed on the butterfly flat board 2, when the 3 stressed generations of circular arc laminated spring were out of shape, the relative position that magnet steel 5 and Hall element are 6 changed thereupon.This variable quantity be that the size that the people applies power by bike the time is directly proportional at circular arc laminated spring 3 stressed generation deflections.Therefore, the deflection of circular arc laminated spring 3 can change by the relative position of 6 of magnet steel 5 and Hall elements and is converted into electric signal.The size of electric signal has just reflected the size of the power that applies when the people by bike.Because axis 1 rotates with sprocket wheel 4, this electric signal is just rotation thereupon also, utilize brush 7 that signal is drawn, just the output power of motor can have been regulated, thereby the output power that applies the size of power when reaching according to the people by bike and regulate motor is promptly regulated the purpose of bicycle power-assist power.
In summary, intelligent sensor for electric boosting bicycle of the present invention structurally only adopts a few components such as butterfly flat board, circular arc laminated spring, magnet steel, Hall element and brush, has just realized regulating the purpose of bicycle power-assist power.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the present invention, and be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claim of the present invention conversion, the modification of the foregoing description.
