Abstract
The invention discloses a torque transducer for an electric bicycle. The torque transducer has a simple structure. A five way (22) is separated from a bicycle frame and the five way (22) is allowed to be slightly rotated on the bicycle frame. An elastic device for preventing too large rotation angle of the five way (22) and an electronic measurement device are combined to measure the horizontal rotation angle, so that the torque of a chain board (23) or the force of touching a pedal (21) by a ridding person can be deduced.
Description
Technical field
Electric bicycle, bicycle, electro-tricycle, tricycle field.
Background technology
Electric bicycle is a kind of vehicles of very environmental protection.It is out of hand that traditional speed pickup causes electric bicycle to ride easily, and there is serious potential safety hazard in the possibility driving during implementation.And present torque sensor is to measure torque signals from the chain drum of rotation, thereby signals collecting and transmission stability are poor, and production cost is higher, can't really promote on market.
Summary of the invention
The present invention is a kind of electric bicycle torque sensor, and it is simple in structure.Be that five-way (22) is separated with vehicle frame, allow five-way (22) that slight amplification level rotation is arranged on vehicle frame.Restriction five-way (22) anglec of rotation excessive elastic device combines with electronic measuring device and measures the angle that horizontally rotates, thereby instead releases the size that chain drum (24) moment of torsion or the people that rides trample the power of foot-operated (21).Electric bicycle controller can go the output torque size of electric bicycle motor according to the signal of this collection, thereby realizes the combination co-ordination of electric bicycle manpower and electric power.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, this electric bicycle torque sensor is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
This electric bicycle moment sensing principal character: be that five-way (22) is separated with vehicle frame, allow five-way (22) that slight amplification level rotation is arranged on vehicle frame.The size of the power that the angle that the excessive elastic device of restriction five-way (22) anglec of rotation and electronic measuring device horizontally rotate by measurement five-way (22) is anti-when releasing chain drum (24) moment of torsion and trampling foot-operated (21) with the people that rides.
As shown in Figure 1, as enforceable mode in, electric bicycle torque sensor of the present invention is included in the fixedly connecting device (12) on electric bicycle or the bicycle rack, the five-way that can slightly horizontally rotate (22), go up fixing connecting device (23) at five-way (22), and Fig. 1 do not indicate as yet stop the excessive elastic device of five-way (22) anglec of rotation, measure the electronic installation of fixedly connecting device (23) anglec of rotation on five-way (22) or the five-way.
As shown in Figure 2, for the ease of understanding, front-axle beam (11), saddle standpipe (13), and back chain stay (14) etc. purchases into the main body of vehicle frame, fixedly connecting device (12) is fixed on the main body of vehicle frame, and becomes as a whole with main body of vehicle frame.
As shown in Figure 3, for the ease of understanding five-way (22), the fixedly connecting device (23) on the five-way, relatively independent power integral body of chain drum (24) formation.
As shown in Figure 4, when the people that rides trampled foot-operated (21), F3 was that chain (25) is given (24) horizontal pulls backward of whole chain drum, and five-way (22) is the center of circle with its a certain point in middle part just, turns clockwise.
When the people that rides tramples foot-operated (21), the top tension of the chain (25) on electric bicycle or bicycle the right, chain (25) is given (24) horizontal pulls backward of whole chain drum, and chain drum (24) conducts this power to five-way (22) by axis.Five-way (22) right side just obtains a horizontal pull backward, and the stationary installation (23) on five-way (22) and the five-way has the rotation of a certain angle at this moment.Specific elastic device can limit the suitable rotation amplitude of five-way (22), otherwise chain (25) can because and chain drum (24) not on same plane, come off.Electronic measuring device is by releasing the size that the moment of torsion of chain drum (24) and the people that rides trample the power of foot-operated (21) to the measurement of angle of the stationary installation (23) on five-way (22) and five-way rotation is counter.Thereby realization realizes measuring accurately to the size of the moment of torsion of the chain drum (24) of electric bicycle and the power that the people that rides tramples foot-operated (21).
The meaning of this electric bicycle torque sensor invention is: the signal that controller comes according to the collection of electric bicycle torque sensor is controlled the motor output torque of electric bicycle, reach human-computer interaction, really realize allowing electric bicycle manpower and electrodynamic organic coordination work.Thereby allow the stronger safety and comfort of riding of electric bicycle, the course that continues is longer.
The meaning of this electric bicycle torque sensor invention also is bicycle, and the people that rides can trample the size of the power of foot-operated (21) with old the comparatively cheap measuring and calculating electric bicycle people that rides when riding.
