Description
Technical field
The utility model relates to a kind of speed sensor of Electrical Bicycle, especially a kind of assistant sensor of stepping on control Electrical Bicycle rotating speed by pin.
Background technology
Electrical Bicycle day by day rises in China as pollution-free, low noise green traffic instrument, is received by more and more people.But existing Electrical Bicycle, generally control the horsepower output of motor by electricity startup and operator handle, therefore make Electrical Bicycle lose pin substantially and step on power-assisted function, therefore run into extraneous resistance factors such as ripple, contrary wind than greatly the time, owing to be subjected to the restriction of motor horsepower output, giving rides brings difficulty.At present, though some Electrical Bicycles are arranged, can step on the horsepower output of power-assisted starter motor and control motor by pin, as a kind of be by speed sensor control motor horsepower output, its structure is by Hall element bicyclist's pin to be stepped on the power output that power conversion becomes motor, but this kind structure must be stepped on the bicyclist or stops stepping on and judge, the control circuit complexity by special signal processor unit, not only reliability of service is not high, but also increases the cost of Electrical Bicycle.Another kind is a pressure sensor, be that the displacement that the follower that will contact with chain produces passes through leverage, the size that magnet steel on the pickup arm and the Hall element generation relative position on the mount pad are changed is controlled the power output of motor through hall element output signal.But the pressure sensor deficiency of this kind structure is, complex structure when being contained on the Electrical Bicycle, must be debugged the thrust of follower and chain, and difficulty is installed, and same reliability of service is not high.
Summary of the invention
A kind of a kind of simple in structure, low cost of manufacture that provides is provided the utility model, and easy for installation, service-strong Electrical Bicycle pin is stepped on the rotating speed assistant sensor.
The utility model is that the technical scheme that achieves the above object is: a kind of Electrical Bicycle pin is stepped on the rotating speed assistant sensor, it is characterized in that: comprise the shell that is fixedly connected on the intermediate axle housing, the inner ring of captiveing joint with axis, and be arranged on centre circle between shell and the inner ring, magnet steel more than two is inlaid on the centre circle, Hall element is inlaid on the shell, voussoir that inner ring is provided with and the active fastening block on the centre circle constitute one-way clutch mechanism, and also have the active fastening block formation one-way clutch mechanism of voussoir and centre circle on the housing.
The utility model adopts the advantage after the technique scheme to be: shell of the present utility model and centre circle, be provided with two independently one-way clutch mechanisms between centre circle and the inner ring, therefore ride pin forward when stepping on power-assisted as the bicyclist, then being connected the joint of inner ring by one-way clutch mechanism on the axis drives centre circle and rotates together, make magnet steel that is inlaid on the centre circle and the Hall element that is inlaid on the shell do relative motion, deliver to the controller processing by the impulse singla that Hall element produces, reach intelligent power-assisted, and bicyclist's pin is when stepping on axis and moving backward, then inner ring separates with one-way clutch mechanism between the centre circle, and the free-wheel clutch combination between shell and the centre circle, at this moment, centre circle is done relative motion with inner ring, and centre circle is static relatively with the outer ring side, so Hall element does not produce impulse singla, motor can not turn round, and realizes the control of power-assisted revolution speed sensing mechanically, not only simple in structure, and low cost of manufacture.The utility model is directly installed on shell and inner ring on axle housing and the axis, and is easy for installation, and need not debug when installing, and uses reliable.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the utility model inner ring when engaging with centre circle.
Fig. 2 is the structural representation of the utility model shell when engaging with centre circle.
The specific embodiment
Electrical Bicycle pin of the present utility model is stepped on the rotating speed assistant sensor, comprise by fastener and being connected on the intermediate axle housing 8, and be sleeved on shell 1 on the axis 9, be fixedly connected on the inner ring 6 on the axis 9, and be contained in centre circle 3 between shell 1 and the inner ring 6, uniform a plurality of magnet steel 4 are inlaid on the centre circle 3, and 10 of Hall elements are inlaid on the shell 1, the active fastening block 5 that inner ring 6 is provided with on voussoir 6-1 and the centre circle 3 constitutes one-way clutch mechanism, the active fastening block 2 that housing 1 also has on voussoir 1-1 and the centre circle 3 constitutes one-way clutch mechanism, at shell 1, be provided with two relatively independent one-way clutch mechanisms between centre circle 3 and the inner ring 6.
As shown in Figure 1, Electrical Bicycle pin of the present utility model is stepped on the power-assisted tachogen, its magnet steel 4 is inlaid on the neighboring of centre circle 3, Hall element 10 is inlaid on the inner periphery of shell 1, voussoir 6-1 on the inner ring 6 sets within it on the end face, constitute one-way clutch mechanism with the active fastening block 5 on centre circle 3 end faces, the voussoir 1-1 of housing 1 end face that also sets within it, constitute one-way clutch mechanism with the active fastening block 2 on centre circle 3 end faces, when the bicyclist drives forwards axis 9 rotations, the major part of inner ring 6 its voussoir 6-1 that together rotate with axis 9 is connected on the active fastening block 5 on centre circle 3 end faces, this moment, one-way clutch mechanism engaged, driving centre circle 3 rotates together, magnet steel 4 on centre circle 3 peripheries is done relative motion with the Hall element 10 on shell 1 inner periphery, the impulse singla that produces by Hall element 10 is delivered to controller and is carried out computing relatively, can draw power-assisted time length and watt level that motor should provide immediately, thereby reach intelligent power-assisted.When bicyclist's pin is stepped on axis 9 and is moved backward, then its microcephaly of voussoir 6-1 on the inner ring 6 contacts with the microcephaly of the active fastening block 5 of centre circle 3, one-way clutch mechanism is separated, at this moment, centre circle 3 is done relative motion with inner ring 6, and centre circle 3 engages with one-way clutch mechanism between the shell 1, and centre circle 3 is relative static with shell 1, so Hall element 10 does not produce impulse singla, motor can not turn round.Be further simplified structure, centre circle 3 is provided with through hole, and spring is housed in the through hole, and both ends of the spring is connected with active fastening block 5,2 respectively, makes active fastening block 5,2 indentations and resets by spring.
