Abstract
The invention relates to a power steering sensor for an electric bicycle, which can be widely used and quickly installed and be used for accurately controlling a motor to work. The power steering sensor is installed on a flywheel of the electric bicycle and can be quickly installed without dismantling a chain wheel crank and a centre shaft. The power steering sensor is universal in all motorcycle types with riding functions. A hall element and a stable magnetic field are encapsulated inside an insulating shell, and the magnetic field is positively and reversely cut through the flywheel of the electric bicycle so that the hall element generates different signals to be provided to a controller so as to control a work state of the motor.
Description
Affiliated technical field
The present invention relates to a kind of electric bicycle power-assisted sensing and adorning, especially can be simply, Fast Installation, accurately control the duty of electric bicycle motor.
Technical background
1. present, known electric bicycle assistant sensor is to be controlled the electric motor starting of electric motor car and stopped by Hall element, magnetic links.The installation site needs specific purpose tool dismounting sprocket crank and bottom bracket cup group to make the extremely inconvenience that seems is installed at the sprocket crank place.How much quantity of magnet steel also can influence the work of sensor simultaneously.Sensor needs sprocket rotation half-turn or 1/3 circle to cause earlier and starts slowly when starting working.When sensor quits work, can occasion a delay, need just can quit work after a period of time, cause the power consumption that delays work and increased useless to make easily to ride mileage to descend.
2. in order to overcome prior electric bicycle assistant sensor shortcoming, this invention is not only easy for installation, quick, and stopping fast when also having guaranteed working sensor avoids delaying work.Cancel the use of magnet steel simultaneously, optimized Design of Sensor.Make to install to seem quick and convenient, need not to dismantle any parts on the electric bicycle, use general utility tool can accomplish the whole erection process.
Summary of the invention
Constant in order to overcome the installation of prior electric bicycle assistant sensor, the deficiency of delaying work easily, it is a kind of easy for installation that the present invention provides, and controls accurate electric bicycle assistant sensor.Can be in the extremely short time, control signal is sent in rapid reaction, reaches once the work of opening, once closing the accurate state of a control that stops.Owing to optimized the design of original assistant sensor, make the single of parts change simultaneously, be easy to install, under the situation of not dismantling any parts on the car, use general utility tool can accomplish the installation of this assistant sensor.
Embodiment
The technical solution adopted for the present invention to solve the technical problems is: in insulation crust, seal a Hall element and a stable magnetic field.Install and fix this invention electric bicycle flywheel or two wheel crank places and use fixing fitting to give to fix during use.Make the tooth of the input face positive alignment flywheel of this sensor, between keep 1 to 1.5mm distance.When the flywheel forward rotation, detection faces produces the action of forward cutting magnetic field, makes Hall element sense changes of magnetic field, comes the control signal of output motor work, offers the acceleration and the deceleration of controller control motor.When the flywheel counter-rotation perhaps stops operating; Detection faces produces in the other direction, and the action or the magnetic field induction line of the cutting magnetic field line of induction remain unchanged; Make Hall element sense changes of magnetic field and perhaps do not have any variation; Assistant sensor stops the control signal of output motor work immediately, and controller stops the power supply output of motor accordingly.Can realize the two-way signaling output of assistant sensor, control the different conditions of motor respectively.
Beneficial effect of the present invention
1. easy for installationly can directly be installed to the flywheel place or sprocket wheel goes out, need not to dismantle the car upper-part.
2. the cutting of output signal reverse side stops to export signal in the time of the positive cutting of two-way control
3. quick and precisely only need small rotation can export signal immediately
4. simple in structure do not have magnet steel to get final product work
5. can simplify installation process and control electric machine operation state accurately.
Claims (3)
1. be a kind of electric bicycle assistant sensor.It is characterized in that, in insulation crust, seal a Hall element and a stable magnetic field, need not to install traditional magnetic links and produce magnetic field, comprised stable magnetic field in inside of the present invention.
2. electric bicycle assistant sensor according to claim 1 is characterized in that, on electric bicycle assistant sensor workplace, applies an action of doing the positive dirction cutting magnetic field line of induction, and Hall element promptly produces voltage signal according to cutting speed.
3. electric bicycle assistant sensor according to claim 1 is characterized in that, when the magnetic field lines of magnetic induction was reversed cutting, Hall element can stop voltage signal according to the variation of magnetic field induction line.
