Description
Technical field
The invention belongs to magnetic induction the technical field of signal is provided, particularly relate on rotatable parts, carry out the technology that multi-point magnetic induction provides control signal.
Background technology
The Chinese patent 201020295192.0 of Yebao Vehicle Material Industry's application " hooking pawl formula moment sensor " discloses a kind of morpet sensing device, sensing device comprises that magnetic part and elastic component coordinate, and experience the sensing device of moment.After period of service was long, the elasticity modulus variation of elastic component will cause the control effect of transducing signal and controlled motor to change, and the power-assisted effect becomes and need to mismatch with people's power-assisted.And complicated with the project organization of elastic component, manufacturing cost is high.
The Chinese patent 01201843.0 " automatic detecting device of electric booster bicycle " of University of Science ﹠ Technology, Beijing's application discloses a kind of automatic detecting device of electric booster bicycle, no touch detects to be pedaled power, speed and turns to, this device is established respectively magnetic sheet on the inside and outside wheel disc of relative motion, on interior wheel disc, spring is arranged, use spring reset between inside and outside wheel disc, the electric signal of surveying the magnetic sheet generation of relative motion on inside and outside wheel disc with two Halls on support represents to pedal power, speed and turns to.
Shortcoming (1) is not durable with elastic component: after period of service was long, the elasticity modulus variation of elastic component will cause the control effect of transducing signal and controlled motor to change, and the power-assisted effect becomes and need to mismatch with people's power-assisted, complex structure, and cost is high.
each magnetic sheet group of shortcoming (2) is identical and the magnetic pole set-up mode is all identical, and can not represent the position separately of different magnetic sheet groups, can not express the special power-assisted demand of diverse location: from Fig. 3 of 01201843.0 patent, 4, 5, 6 and the record explanation of the 2nd section of Instructions Page 2, each magnetic sheet group (comprises a magnetic sheet 4, a magnetic sheet 5, a magnetic sheet 6) magnetic pole set-up mode is all identical, only namely simply from being provided with again identical magnetic sheet group at interior diverse location of taking turns, the position separately that can not represent different magnetic sheet groups, the state of kinematic motion that can not represent ad-hoc location, and the people is by bike the time, pedal with each position corresponding with pedal at state of kinematic motion, own special power-assisted demand is arranged, but the identical structure of this each magnetic sheet group of this patent, can not give expression to the special power-assisted demand of each diverse location on pedal.
Each site signal indifference of shortcoming (3) makes man-machine mismatching: each magnetic sheet group is the same, each magnetic sheet group can not represent the position of this magnetic sheet group on interior the wheel, the signal that Hall is exported can not represent the position of stretcher and other magnetic sheet group, the signal that is Hall output can not represent that different foot positions are to the demand of power-assisted, cause the demand of power-assisted and provide the time of power-assisted to mismatch, namely man-machine cooperation is undesirable.
The shortcoming sine wave output makes the magnetic sheet group Edge Distance can not be less than 4 centimetres, generally take 5 centimetres as good, can establish magnetic sheet group number very little and make, man-machine cooperation is undesirable: each magnetic sheet group is identical, Hall output is that sinusoidal waveform is as control signal, as the control signal sinusoidal waveform, certain peak valley difference must be arranged, because the magnetic sheet group of this patent needs certain-length to represent forward and reverse motion, be to establish at most 8 magnetic sheet groups on the rolling disc circular trace of 20 centimetres at diameter, generally take 5 as good, Hall just can have the sine wave signal of controlling function.That is to say, this technical scheme of 01201843.0 patent is used for morpet, magnetic sheet group limited amount only in 8, control signal very little, man-machine cooperation is undesirable.If but more than 8 magnetic sheet groups, when people's treadmill was very fast, the signal graph of Hall output was close to a horizon, this signal is not controlled function, can not control electrical motor, when making it need power-assisted especially, loses assist function.
Shortcoming (5) signal blind zone reaches miter angle, really can not get power-assisted when needing power-assisted during startup: well-known, it is minimum in summit moment that the people steps on bicycle pedal, the zone that needs most power-assisted from leaving 10-45 degree angle, summit, but the angle between each magnetic sheet group of this patent is 45 degree, leaves summit 10-45 degree angular zone neither one magnetic sheet group at stretcher, also with regard to the neither one control signal, when consequently needing most power-assisted, but the motor of morpet really can not power-assisted.
In a word, except with the not durable complex structure again of elastic component, fit structure characteristics because of Hall and magnetic sheet group, the rotating disk size diameter is in 20 centimetres, and having placed restrictions on magnetic sheet group quantity is 8 groups, and magnetic sheet group number can not arbitrarily increase, make man-machine cooperation undesirable, and can not get power-assisted when starting, the power-assisted demand with provide power-assisted not mate, cyclist's traveling comfort is poor; As increasing by force magnetic sheet group quantity, its transducing signal loses again the Power assisted control function.
The Chinese patent 03264387.X " timing sensor of electric boosting bicycle " of Wang Naikang application discloses without elastic component, only with moving, fixed two rotating disks, inlay two permanent magnetic steels above Moving plate, inlay three Hall elements above price fixing, bicycle pedal circles, each Hall produces two pulses, and three Hall elements produce six pulses.Divide folding can get three characteristics, four shortcomings are as follows:
Characteristics (1) are for obtaining six impulse singlas, can only be each permanent magnetic steel same pole in one side: each Hall will produce two pulses, can only be the same face that the same pole of two permanent magnetic steels is located at Moving plate, namely in certain one side of Moving plate, two permanent-magnet magnetic steel capital be the arctic or be all the South Pole.If at the same face of Moving plate, a permanent magnetic steel is the arctic, another is the South Pole, and pedal circles, and each Hall just can only produce a pulse, and three Halls just only have three pulses, and this does not just conform with this patent specification and has put down in writing.In order to increase pulse count, improve and control effect, can only be that each permanent magnetic steel same pole is in one side.
Characteristics (2) permanent magnetic steel is for expression pedal fixed position, three Halls represent the pedal travel position: because pedal and Moving plate are to synchronize rotation, so a permanent magnetic steel is fixed respectively in two positions on the Moving plate corresponding with two pedals, where some pedals turn, and where corresponding permanent magnetic steel also turns; But only turn in the position that Hall is arranged, could send control signal by Hall, the motor of commander's morpet produces the power-assisted that needs and rotates.
The position of characteristics (3) middle different period pedal travels because Hall can not represent to circle, just can not be only with a Hall: the different periods of pedal in circling, the power-assisted demand there is very big difference, embody the variation of this power-assisted demand, this patent is located at respectively 180 with three Halls and spends the angle with three interior positions, two permanent magnetic steels are located at respectively two pedal positions, pedal turns in the position that Hall is arranged, and this Hall represents that with regard to output signal pedal has arrived the position of this Huo Yuan.But there is again following shortcoming with a plurality of Halls.
These characteristics as the morpet sensor have three shortcomings:
Shortcoming (1) represents respectively the fixed position of two pedals with two permanent magnetic steels that there is no an otherness, just can only represent with a plurality of Halls the turned position of pedal: two permanent magnetic steels do not have otherness, advantage is can be regardless of the fixed position that represents respectively two pedals of left and right pin, make its left and right human hair combing waste give birth to the power-assisted demand, can produce identical motor power-assisted effect; But shortcoming is permanent magnetic steel itself just can not represent the turned position of pedal, and can only be located at the turned position that different angle positions represents pedal with a plurality of Halls, thus can not be only with a Hall, and must use a plurality of Halls.
Shortcoming (2) can not be only with a Hall, and three Halls must cause three control signals that original segmentation error is arranged, make the distortion of power-assisted demand model, naturally produce power-assisted output inconsistent with the power-assisted demand: no matter morpet is one or two motor, its transducing signal of controlling motor can only just can reach the purpose of controlling motor with a transducing signal input electric machine controller; And this patent is controlled motors with three Halls, must merge into one to three control signals of three Halls and could input electric machine controller after merging control signal.The parameter sensing of three Halls can not be the same, particularly due to after variation of ambient temperature, period of service length, the parameter sensing of three Halls may be widely different, when its result causes identical power-assisted demand, the output of different Halls be different voltages, cause motor to produce different power-assisted output, power-assisted output is inconsistent with the power-assisted demand; In like manner during identical power-assisted demand, the output of different Halls may be identical voltage again, cause motor to produce the output of same power-assisted, also produce power-assisted output and the inconsistent problem of power-assisted demand.
shortcoming (3) merges control signal and easily produces signal drift, merging control signal and electric machine controller are not mated, power-assisted demand model distortion: due to variation of ambient temperature, after period of service is long, the parameter sensing of three Halls may be widely different, three control signal point of connection of three Halls must change, the merging control signal of identical power-assisted demand generation will produce the signal drift of segmenting, merge control signal as a whole signal distortion that produces, it is the distortion of power-assisted demand model, any one that causes that electric machine controller selects three control signals all can produce power-assisted output and the inconsistent problem of power-assisted demand as benchmark.
Shortcoming sensing site can not arbitrarily increase, the sensing site very little, the motor operation is just not steady, make people by bike feel very uncomfortable: owing to shortcoming (1) and shortcoming (2) being arranged all because Hall quantity causes greater than one, clearly Hall quantity is measured more and more, and shortcoming (1) and shortcoming (2) performance are more serious.So the morpet that this patent provides can only be to make people by bike feel the morpet that traveling comfort is very bad.
Shortcoming (5) signal blind zone reaches 42 and spends the angle, really can not get power-assisted when needing power-assisted during startup: well-known, it is minimum in summit moment that the people steps on bicycle pedal, the zone that needs most power-assisted from leaving 10-45 degree angle, summit, but the angle between each Hall of this patent is the 42.5-43.5 degree, leaves summit 10-42 degree angular zone neither one Hall at stretcher, also with regard to the neither one control signal, when consequently needing most power-assisted, but the motor of morpet really can not power-assisted.
In a word, this patent is to control the technical scheme of assistant mode with a plurality of Halls, because can only represent with a plurality of Halls the turned position of pedal, a plurality of control signals of a plurality of Halls must have original error, it merges control signal and easily produces again signal drift, all can cause the distortion of power-assisted demand model, i.e. the identical power-assisted demand of different time, but obtain different power-assisted effects; Hall quantity is measured more and more, and the distortion of power-assisted demand model is more serious, the quantity of having placed restrictions on you, the Hall small number and to produce the motor operation just not steady, make people by bike feel very uncomfortable, and can not get power-assisted when starting.Make it want the power-assisted demand model undistorted, and want motor to operate steadily and always attend to one thing and lose sight of another on these two problems, can not get both.
International Patent Application WO/099/13558AI discloses the sensor that is used for controlling on electrical motor electrical motor, this sensor is that depression is set on rolling disc, permanent magnets is entrapped in the depression of rolling disc, depression and the essential size shape no-float of permanent magnets, this point is difficult to accomplish.Because caved in greater than permanent magnets, rolling disc is when rotating, and permanent magnets is vibrated in depression, very fragile permanent magnets; Depression is the flush fit permanent magnets, is difficult to again permanent magnets is entrapped in the depression of rolling disc.So, can only be the fixed position in the disposable depression that is permanently affixed at rolling disc of permanent magnets, make its at rolling disc when rotating, permanent magnets can not vibrated.But such structure has been placed restrictions on permanent magnets and can have been regulated in the depth of rolling disc, causes a sensor to only have a kind of sensing model.
Summary of the invention
Only the purpose of this invention is to provide with each permanent magnets on a Hall and rolling disc and obtain the sensitive member that speed and acceleration signal and sensor can have multiple sensing model, but be a kind of in induction region, can increase permanent magnets quantity as far as possible, utilize to greatest extent the rolling disc displacement information, how again output information pinpoint sensitive member.Use is measured moment without elastic component and other machinery on morpet, also can make the power-assisted demand good with the power-assisted coupling that provides, the morpet sensor sensitive member that motor operates steadily.
Design of the present invention is: a sensor can be adjusted to multiple sensing model, as long as rolling disc is connected the mode that to regulate the depth connect with permanent magnets, namely connect with screw, just can not change under locality condition in permanent magnets, regulate permanent magnets to the magnetic induction density of Hall by regulating the depth, make the different transducing signal of Hall output, obtain different control models.But in a Hall receptive field, carry out different variation pattern settings with a plurality of permanent magnets on a rolling disc, make an one Hall can experience the motor message of whole permanent magnets.The variation pattern of a plurality of permanent magnets is mainly that magnetic polarity changes, magnetic flux change, purpose make Hall can obtain ad-hoc location more accurate, control stronger, the more permanent magnets motor message of function.A plurality of permanent magnets magnetic polarities alternately change with the arctic, the South Pole, and the signal that Hall is produced is square wave, control function stronger, more; It is more accurate that a plurality of permanent magnets magnetic flux change make signal that Hall produces can express the position of permanent magnets, thereby can express the state of kinematic motion of ad-hoc location.For morpet, the ad-hoc location of expressing stretcher is extremely important at what state of kinematic motion because the state of kinematic motion direct representation of stretcher the power-assisted need state of people to car.
Structure of the present invention is:
The rotating disc type sensitive member of many magnetic patch uneven distribution magnetic flow, comprise a rolling disc 1 and a plurality of permanent magnets 2, it is characterized in that: be fixedly installed a plurality of permanent magnets 2 on rolling disc 1, these a plurality of permanent magnets 2 rounded track equably distribute, and namely each permanent magnets 2 is identical to the distance between identical, the adjacent permanent magnets 2 of distance at circular rail trace 5 circle centers, place; In certain one side of rolling disc 1, the magnetic polarity of adjacent permanent magnets 2 is opposite, and namely simultaneously to go up the magnetic polarity distribution mode of whole permanent magnets 2 be the N utmost point, the S utmost point, the N utmost point, the S utmost point, the N utmost point, the S utmost point for certain of rolling disc 1 Have at least the magnetic flow of two permanent magnets 2 not identical, and to have a permanent magnets 2 at least be with being threaded with hole on rolling disc 1;
Also comprise a Hall 3, Hall 3 is positioned at certain one side of rolling disc 1, and Hall 3 is located near permanent magnets 2 also can experience the position of permanent magnets 2 magnetic flow, between Hall 3 and permanent magnets 2, spacing is arranged; Hall 3 is opposite magnetic polarities to be produced the Hall of square wave output signal.
Rolling disc 1 can be the on-deformable plate of material such as plastic flagstone, the exhausted plate of high strength, copper coin, aluminium sheet.When using sensitive member, rolling disc 1 will rotate, and the center of rotation is exactly that 2 one-tenth annular arrangement distributions of a plurality of permanent magnets are at the center of circle.
The purpose that 2 one-tenth annular arrangements of a plurality of permanent magnets distribute is only to experience the state of kinematic motion of whole permanent magnets 2 on rolling disc with a Hall 3, namely experience movement position and the speed of whole permanent magnets 2 on rolling disc, and the variation of speed, or title acceleration/accel, this Hall 3 just can be expressed the state of kinematic motion of permanent magnets 2 with a continuous electric signal, because it is on rolling disc 1 that whole permanent magnets 2 is separately fixed at rolling disc, the continuous electric signal of Hall 3 generations just can be expressed the state of kinematic motion of rolling disc again.If this continuous electric signal is used for controlling other object, this continuous electric signal is exactly control signal.If be used for controlling the motor of morpet, also need with micro controller system or other electron component as sensing signal processor, position in control signal, speed, acceleration/accel key element are converted to need what power-assisted signal of power-assisted, the function that converts is exactly the power-assisted demand model, or claims the power-assisted model.
The not identical meaning of a plurality of permanent magnets 2 magnetic flow is: making in the electric signal that Hall 3 produces is not duplicate impulse singla, but the different impulse singla of peak valley difference, distinguish the diverse location of different permanent magnets 2 with distinguishing impulse singla, thereby can obtain the state of kinematic motion of diverse location permanent magnets 2.But reach accurate expression rolling disc certain position, or each there is the state of kinematic motion of permanent magnets 2.As being used for morpet, but accurate expression ride in the demand of diverse location to power-assisted, make the expression of power-assisted demand more accurate, car is just more consistent with people's cooperation.
The not identical namely magnetic flow of a plurality of permanent magnets 2 of a plurality of permanent magnets 2 magnetic flow is vicissitudinous, the scope of its variation should be the sensitive magnetic flow scope of the same Hall 3 of invariant position, that is to say, the peak of a plurality of permanent magnets 2 magnetic flow and minimum should be in the sensitive magnetic flow scopes of Hall 3.
Hall 3 is located near permanent magnets 2 also can experience the position of permanent magnets 2 magnetic flow, and purpose is to experience with Hall 3 state of kinematic motion of permanent magnets 2, i.e. movement position, speed, acceleration/accel.
the control initial point meaning that is threaded: Hall 3 will be experienced the movement position of rolling disc 1, Hall 3 just must will have the waveform difference, identical in many pieces of permanent magnets 2 sizes, shape is identical, magnetic flow is identical, under the condition that rounded track distributes equably, Hall 3 will obtain the waveform difference, be that Hall 3 will obtain distinguishing waveform, only has the distance of regulating permanent magnets 2 and Hall 3, make the same permanent magnets 2 of 3 pairs of same positions of Hall obtain different magnetic flow, thereby be different waveforms before and after obtaining to regulate, this different waveform is different from the waveform of other permanent magnets 2, make its this different waveform can make Hall 3 experience the movement position of rolling disc 1.Permanent magnets 2 is just to regulate the distance of permanent magnets 2 and Hall 3 with being threaded with rolling disc 1, so this structure can make Hall 3 experience the movement position of rolling disc 1.This Hall 3 signals that position mark is arranged can provide the control initial point as control signal, and do not have the control signal of waveform difference that the control initial point can not be provided.
The adjusting mode that is threaded has following four kinds at least:
The first, permanent magnets 2 is goed deep into position adjustments to annular groove rolling disc 1, make it away from Hall 3, the magnetic flow that Hall 3 receives this point reduces, and reduces corresponding to the signal of the output of this point;
The second, permanent magnets 2 is regulated to the shallow out position of annular groove rolling disc 1, make it near Hall 3, the magnetic flow that Hall 3 receives this point strengthens, and increases corresponding to the signal of the output of this point;
The third, permanent magnets 2 is taken out annular groove rolling discs 1, make this position there is no permanent magnets 2, the magnetic flow that Hall 3 receives this point is zero, is zero corresponding to the signal of the output of this point;
The 4th kind, permanent magnets 2 is taken out annular groove rolling discs 1 after, reverse the rotating into again in original annular groove rolling disc 1 hole in permanent magnets 2 South Pole of this taking-up and the arctic, make the permanent magnets 2 of this position identical with the magnetic pole of adjacent two permanent magnets 2, Hall 3 is received three identical magnetic poles continuously near this point, the wide ripple signal that three equidirectional waveforms of Hall 3 outputs merge.
The adjusting mode meaning that is threaded: it is identical at each parts of sensitive member namely regulate controlling the model meaning, and under the condition that namely each parts sections does not change, at different time, Hall 3 can be exported different waveform signals, produces different control models.If this sensitive member is arranged on a morpet, can realize riding on level road with a power-assisted model, when riding on the hill path, as long as permanent magnets 2 is deeply regulated away from Hall 3 to rolling disc 1, Hall 3 can be exported again another sample waveform signal, is suitable for the power-assisted model of riding in the hill path thereby this waveform signal makes again electrical motor produce another to morpet.Due to regulate permanent magnets 2 to rolling disc 1 deeply or shallow go out very convenient, so, regulate the different waveform signal of Hall 3 outputs also very convenient, regulate morpet and be the different road conditions such as level road or hill path and carry out power-assisted and ride very convenient.
The magnetic polarity of adjacent permanent magnets 2 is very important technical characterictic on the contrary, all the magnetic polarity distribution mode of permanent magnets 2 is the N utmost point, the S utmost point, the N utmost point, the S utmost point, the N utmost point, the S utmost point ... make the Hall 3 high and low alternate square-wave signals of output, the rolling disc that stops as limited size, rotating the accurate variable signal that will obtain in a week as much as possible, should be to select square wave certainly.Because the time that the peak-to-valley value of square-wave signal changes is short, can within the regular hour, produce the signal of controlling meaning that has as much as possible.The structure generation square wave that the magnetic polarity of adjacent permanent magnets 2 is opposite, and the identical structure generation sinusoidal waveform of the magnetic polarity of adjacent permanent magnets 2, during especially for morpet, generally placing restrictions at diameter as the rolling disc of sensing element is 10-15 centimetre, to obtain to control the signal of function in this limit scope, rotate a week, produce square wave than producing the available pulse number of sinusoidal waveform and many 7-9 doubly.Nature, the opposite structure of the magnetic polarity of adjacent permanent magnets 2 to the control effect of morpet more, the people coordinates with car better, the rider people feels more comfortable.
Hall 3 is located at over against the position of the circular rail trace 5 of a plurality of permanent magnets 2.Because Hall 3 is to have spacing to experience permanent magnets 2 magnetic flow and the parts of output electrical signals, again in order to reduce the volume of permanent magnets 2 as far as possible, make its on rolling disc 1 as much as possible permanent magnets 2 is set, the permanent magnets 2 that as far as possible reduces can be responded to by Hall 3; Hall 3 should be located at over against the position of the circular rail trace 5 of a plurality of permanent magnets 2, can run through the position of the circular rail trace of whole permanent magnets 2.
Described permanent magnets 2 and rolling disc 1 use screw connection point also are provided with the fixedly connecting element of permanent magnets 2 and rolling disc 1 relative position.Permanent magnets 2 is regulated deeply or shallow go out rolling disc 1 after, permanent magnets 2 positions after should secured adjusted are so will fix permanent magnets 2 positions after regulating with connecting element.Connecting element can be selected the modes such as rubber cushion, spring chair or nut 6.Make its same sensitive member, can easily be adjusted to multiple electric signal model output.
Preferred connecting element is the nut 6 on permanent magnets 2.With the shredded meat number of turns of nut 6, easily judge with the naked eye that permanent magnets 2 is regulated deeply or the shallow size that goes out rolling disc 1, be suitable for more extensive, anyone permanent magnets that can operate 2 control methods.
Rolling disc 1 is provided with centre hole in the circular rail trace 5 place circle scopes of a plurality of permanent magnets 2.If rolling disc 1 will be set on a turning cylinder and use, will establish a hole that wears turning cylinder on rolling disc 1; For guaranteeing rolling disc 1 when rotating with turning cylinder, Hall 3 can be experienced the motor message of each permanent magnets 2 on rolling disc 1, wears the center that scopes are justified at circular rail trace 5 places that the hole should be located at a plurality of permanent magnets 2, i.e. centre hole on rolling disc 1.That is to say, centre hole is not necessarily circular, can be the shapes such as square, triangle, in order to can be nested with the turning cylinder of the shapes such as square, triangle, but the interior sky of centre hole necessarily comprises the center of circular rail trace 5 place circles, could use a Hall 3 to experience the motor message of whole permanent magnets 2 on rolling disc 1 rolling disc.
Have at least the magnetic flow of a permanent magnets 2 to be not equal to the magnetic flow of other any one permanent magnets 2.The magnetic flow that is not equal to other, namely special values of magnetic flux can be used for representing the position of bicycle pedal.Preferably have at least the magnetic flow of two each and every one permanent magnets 2 to be not equal to the magnetic flow of other any one permanent magnets 2, the permanent magnets 2 of these two special values of magnetic fluxes corresponds respectively to two stretchers, is used for the position of two stretchers of expression bicycle.Because the circular movement of bicycle pedal is judged pedal position for the speed that obtains this circular movement, determine that the power-assisted model of circular movement is extremely important next time.
Rolling disc 1 is plastic flagstone, aluminum board, copper material plate a certain of non-magnet_conductible material.Be the opposite structure of magnetic polarity of adjacent permanent magnets 2 due to the present invention, can make the edge of adjacent permanent magnets 2 almost can be affixed the electric signal that also can make Hall 3 outputs that the control function is arranged.Plastic flagstone, aluminum board, the copper material plate of handy non-magnet_conductible material, or other on-deformable rolling disc.
advantage of the present invention: simple in structure, cost is low, permanent magnets quantity on the permanent magnets ring is not placed restrictions on, not at the impulse singla of the exportable standard in the permanent magnets position of adjustable magnetic flux, there is no signal blind zone, only with one group of output signal of Hall total movement state of energy perfect representation Moving plate just, output signal can not drift about in distortion, magnetic flux change with permanent magnets represents the fixed position, place, in output signal, the movement position of each permanent magnets can be arranged, be used for morpet, make power-assisted output can highly coordinate with the power-assisted demand and the cyclist is felt well.
［ 1 ］ can regulate the model of Hall output signal: the permanent magnets of adjustable magnetic flux can have on rolling disc deeply, shallowly go out, take out break away from, magnetic pole oppositely four kinds of modes such as screw-in be connected with rolling disc, namely there are four kinds of modes to regulate the model of Hall output electrical signals, make its same sensitive member, can easily be adjusted to the model output of other four kinds of electric signal.Signal model changes, and just can select different signal models to control and be controlled object, realizes personalized control.As being used for morpet, can be according to the strength of different people, or the custom of exerting oneself, ride over Plain or mountain region and the signal model selecting to be fit to, namely have the function of regulating at any time power-assisted by personalization.
［ 2 ］ simple in structure, without elastic component, machinery-free fault: rotate output signal with a plurality of permanent magnets of Hall impression, the speed that provides with Chinese patent 01201843.0 can be calculated the principle of moment, available multiple math modeling is calculated the moment parameter of morpet, be used for controlling the motor of morpet, realize power-assisted.Without elastic component, simple in structure, cost lower than with elastic component and mechanically stressed sensor.After having avoided long-time use, each mechanical part distortion, machinery-free fault, the not good problem of cooperation.
［ 3 ］ magnetic polarity is opposite, the output square-wave signal, has accurate control function: because the magnetic polarity of adjacent permanent magnets is opposite, and Hall is selected the Hall that opposite magnetic polarities is produced the square wave output signal, adjacent permanent magnets no matter spacing what, even very close to each other between adjacent permanent magnets, Hall can be exported square-wave signal too.As being used for morpet, the motor of controlling morpet with the output signal of square wave is better than using sinusoidal waveform, because the rectangle wave energy is accomplished signal point at any time, the signal implication of expression movement position and speed is accurate, but thereby the movement position of Precise Representation booster bicycle pedal and speed, in order to go out the correct power-assisted demand of this state of kinematic motion with the accurate position of pedal and speed calculation.
［ 4 ］ magnetic polarity of adjacent permanent magnets is opposite, permanent magnets quantity is not placed restrictions on, can increase the sensing point position: because magnetic polarity is opposite as far as possible, the output square-wave signal, even adjacent permanent magnets gapless, the signal of its output has remained number, differentiable square-wave signal, still has the control function, that is to say to export the unchanged linear signal of not controlling function.As being used for morpet, owing to being placed restrictions on the rolling disc diameter of pedal linkage, just can be on the rolling disc of prescribed level, increase as far as possible permanent magnets quantity, as far as possible increase the sensing point position, represent bicycle pedal movement position and speed, the Precise Representation state of kinematic motion with as much as possible transducing signal.
［ 5 ］ magnetic polarity of adjacent permanent magnets is opposite, can arrange that permanent magnets is many, the sensing point position is many, state of kinematic motion to rolling disc represents accurately: to being used for morpet, fixedly the rolling disc size of permanent magnets is strictly placed restrictions on, general rolling disc diameter can only be in 10-15 centimetre, in order to make Hall that the magnetic pole signal that obtains permanent magnets under the condition of spacing arranged, the diameter of its permanent magnets is at least Ф 0.6-0.8 centimetre, and the rolling disc of diameter 10-15 centimetre peripheral zero-lash arranges 35-73 permanent magnets ［ 10-1*3.14/0.8=35; 15-1*3.14/0.6=73, namely stretcher circles, and Hall can obtain the motor that 35-73 signal is used for controlling morpet.But if the identical prior art of adjacent permanent magnets magnetic polarity, adjacent permanent magnets on diameter 10-15 centimetre rolling disc, can only arrange at most 5-8 permanent magnets ［ 10-1*3.14/5.8=5 by 5 centimetres of spacings; 15-1*3.14/5.6=8.As seen, the art of this patent can arrange doubly ［ 35/5=6 of permanent magnets 7-9 than prior art more; 73/8=9 ］, 30-65 permanent magnets ［ 35-5=30 is set more; 73-8=65 ］.So rolling disc circles, the art of this patent has increased 7-9 turn disc site signal doubly than prior art.Electric machine control accuracy rate to morpet has improved 7-9 doubly naturally, make the cyclist also improve 7-9 doubly to power-assisted demand accuracy rate, car and people's cooperate degree improves greatly, and cyclist's comfort increases greatly, is no longer boosted vehicle the sort of one fast one slow uncomfortable sensation of prior art.The present invention asks someone according to the experience of reality, when roughly 15 permanent magnets being set uniformly on rolling disc, substantially having eliminated prior art and has only established 5-8 permanent magnets and make boosted vehicle the sort of one fast one slow uncomfortable sensation; When roughly 20 permanent magnets being set uniformly on rolling disc, car coordinates oneself can satisfy human needs with the people's, and the sensation of riding boosted vehicle is very comfortable.
［ 6 ］ there is no signal blind zone, the power-assisted that power-assisted demand whenever all can obtain to be complementary: this patent can arrange at most 35-73 permanent magnets at the rolling disc periphery of diameter 10-15 centimetre, and between each permanent magnets, average angle is the 5-10 degree.Be used for morpet, when starting or move, stretcher is spent in the zone from leaving 35 of 10-45 degree angle, summit, there be 4-7 permanent magnets in the position of leaving degree angle, summit 10, a signal just to be arranged, the exportable 4-7 of Hall control signal reacts the power-assisted demand, can realize any position, have power-assisted just can obtain the excellent technique effect of corresponding power-assisted any time, make car and people's no-float, it is laborsaving comfortable again that the cyclist feels.
［ 7 ］ only with a Hall, a control signal represents the total movement state of rolling disc, the state of kinematic motion of control signal and rolling disc is in full accord, control signal and people's demand is in full accord: a plurality of permanent magnets are fixed on rolling disc, permanent magnets is synchronizeed with rolling disc and is rotated, with a whole permanent magnets motor message of Hall impression, the state of kinematic motion of the control signal of Hall output and rolling disc is in full accord, just in full accord with people's demand, control signal does not have original segmentation error and signal drift problem yet.Even the hall sensing parameter changes, be also whole control signal parallel, as long as it is wider to receive the range of receiving of electric machine controller of Hall control signal, the control effect of the Hall control signal that has changed becomes systematicness to change.As being used for morpet, the power-assisted demand model can distortion, and power-assisted output and power-assisted demand still keep the matching relationship of original model, and the systematicness that the cyclist is easy to grasp this power-assisted ability changes.
［ 8 ］ magnetic flow of each permanent magnets changes, the vicissitudinous permanent magnets of magnetic flow can represent the state of kinematic motion of specific site: because the magnetic flow of each permanent magnets changes, each permanent magnets makes the control signal of the peculiar peak valley difference waveform of Hall output, the state of kinematic motion the in control signal of peculiar peak valley difference waveform just can the direct representation rolling disc a certain fixedly permanent magnets site; The given magnetic flux that oneself is arranged as each permanent magnets, what permanent magnets can reach has, and just can obtain the motion state signal of what specific sites.As being used for morpet, the rolling disc diameter is in 10-15 centimetre, and rolling disc circles, and Hall can obtain the control signal of 35-73 different loci state of kinematic motion, naturally knows the power-assisted demand in 35-73 site.Clearly, rolling disc circles, and prior art can only have at most 5-8 power-assisted demand, and being nothing like the maximum available 35-73 of a this patent power-assisted desired signal more can be truly, multiple data quantity ground reaction cyclist's power-assisted demand.That is to say, morpet the art of this patent, Che Gengneng and people's demand match consistent, and the cyclist experiences stretcher at any turned position, but oneself regulation speed fully all, and traveling comfort is good.And but the morpet of prior art can only be at maximum 5-8 turned positions ability regulation speed.
