Description
Technical field
The present invention relates to a kind of intracellular signaling device for Electrical Bicycle, particularly relate to a kind of conducting slip ring for Electrical Bicycle and the power-assisted control method of electric bicycle of this conducting slip ring is installed.
Background technology
Power steering sensor for electric bicycle is applied on intelligent electric morpet, is one of Intelligent electric bicycle core component.Can in different environment of riding, accurately judge the speed of a motor vehicle, and need to change motor output according to difference, thus bring comfortable experience of riding, be current question of common concern.
Therefore, people are in the urgent need to a kind of intracellular signaling device of Electrical Bicycle.The change of pedal force has directly been reacted in the change of the axis moment of bicycle, and the change of this signal is passed to controller, thus the power-assisted of adjustment motor exports, and increases measurement accuracy, obtains experience of better riding.Because axis is rotating in riding, the signal wire (SW) therefore measuring the sensor of axis moment must conduct to the Electric Bicycle Driver be fixedly mounted on vehicle frame.
Conducting slip ring is a kind of matured product of electrical contact sliding block joint, we consider to be applied in measure axis moment system on can solve the problem, in order to obtain better effect of riding, we install speed measuring device on conducting slip ring, coordinate torque signals to conduct together to controller.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of test the speed conducting slip ring and method of operation thereof for Electrical Bicycle, by this conducting slip ring, the signal that the sensor be pasted onto on axis sleeve can be received amplifies, and is passed to controller.Thus change according to the moment of axis and control the output of motor power-assisted, the real intellectuality embodying Electrical Bicycle.
For achieving the above object, technical scheme provided by the present invention is: a kind of conducting slip ring for Electrical Bicycle, be arranged in the moment sensing system of Electrical Bicycle, comprise rotor part and stator department, rotor and axis fix, the position that stator department and relative frame are fixed is fixed, described conducting slip ring is connected with sensor with the controller in described moment sensing system respectively, the signal that described sensor produces sends described controller to by described conducting slip ring, and described controller controls the output of motor power-assisted.
Further, described conducting slip ring also comprises speed measuring device disposed thereon.
Further, described speed measuring device is the magnet ring in circular magnet steel spaced apart installed in described rotor part, at the Hall element that the position corresponding with described magnet ring is installed.
Further, described moment sensing system is provided with strain sleeve, one end of described strain sleeve is fixed on five-way by bearing and is connected with chain wheel support, the other end is sleeved on axis, be fixedly connected with axis, the inside face of described strain sleeve is fitted the outside face of described axis, and the outside face of described strain sleeve pastes described sensor.
A power-assisted control method of electric bicycle for conducting slip ring is installed, comprises:
Detect when testing the speed that the speed of trampling is slow, pedal force corresponding increase time, conducting slip ring is to controller output signal, and controller controls motor to be increased power-assisted and export;
Detect when testing the speed that speed of trampling increases, pedal force corresponding reductions time, conducting slip ring is to controller output signal, and controller controls motor and reduces power-assisted output.
Adopt technique scheme, beneficial effect of the present invention has:
1., by the conducting slip ring for Electrical Bicycle of the present invention, the signal received is amplified, and be passed to controller from the sensor be pasted onto on axis sleeve.Thus control the output of motor power-assisted according to the change of axis moment, the real intellectuality embodying Electrical Bicycle.
2. the present invention preferably arranges speed measuring device on conducting slip ring, such as when the upward slope of riding or descending, the change of pedal force and foot-operated speed can be real-time monitored, by the Programming to controller, change the output of motor power-assisted, thus obtain experience of better riding.
3. because strain jacket casing is on axis, it is bearing fit, there is certain tolerance clearance between the two, even if therefore there is abnormal condition, play on the footrests as there being people to step on during bicycle parking, now axis can produce the lever distortion of trace, this distortion is delivered to after on strain sleeve by tolerance clearance and significantly decays, add that axis rigidity is very strong, deflection own is very little, now strain the moment of torsion that detects of sleeve much smaller than moment of torsion when normally trampling, therefore battery-driven car can not start output motor propulsive effort, send misoperation, overcome the common deficiency of current axis moment sensing system.

Detailed description of the invention
Embodiment 1
With reference to figure 1, the invention provides a kind of conducting slip ring for Electrical Bicycle, it is arranged in the axis moment sensing system of Electrical Bicycle, axis moment sensing system comprises: axis 1, strain sleeve 8, chain wheel support 10, sensor 7 and five-way, one end of strain sleeve 8 is fixed on five-way by bearing 2 and is connected with chain wheel support 10, the other end is sleeved on axis 1, be fixedly connected with axis, the outside face of the inside face laminating axis of strain sleeve, only can there is relative trace and rotate in sleeve and axis, and can not rock up and down.Conduction guiding valve comprises rotor part 3 and stator department 4, rotor 3 and axis 1 or strain sleeve 8 and fix, and the position that stator department 4 is fixed with relative frame is fixed, and conducting slip ring is connected with sensor with the controller in moment sensing system respectively.Constantly trample during owing to riding, axis produces moment, sleeve constantly rotates along with axis, sleeve pipe is subject to rotary torsion slight torsional deflection occurs in this process, sensor is caused to deform, produce pedal moment signal, sensor signal is passed to controller after conducting slip ring amplifies, and controller controls the output of motor power-assisted.Wherein, the sensor half-bridge that can be made up of resistance strain gage or full-bridge circuit are formed.
