Description
Technical field
The utility model relates to a kind of strain sensing device, particularly relates to a kind of torque sensor of electric bicycle.
Background technology
Existing electrically assisted bicycle comprises that a crank axostylus axostyle, two are arranged at respectively the crank of the anti-end of this crank axostylus axostyle two-phase, two pedals that are installed on respectively described crank, two strain sensores that are installed on respectively described crank, and power-assisted unit that is electrically connected to described strain sensor, when trampling described pedal in turn, described crank is stressed and make described strain sensor produce deformation signal respectively, and then drives this power-assisted cell operation and make this bicycle produce power-assisted.
Yet, because described crank stressed is to trample and occur in turn with user's left and right, therefore when one of them crank is stressed, make a crank be in often the state of not stressing, therefore make described strain sensor be in turn idle state, and cause the wasting of resources.
Summary of the invention
The purpose of this utility model is to provide a kind of can measure with a strain sensor torque sensor of electric bicycle of the torsion between this crank shaft and described crank.
The utility model torque sensor of electric bicycle is applicable to be installed on an Electrical Bicycle.This Electrical Bicycle has the crank that a crank shaft that extends along axis direction, two are arranged at this crank shaft two opposite ends, reaches a power-assisted unit.This torque sensor of electric bicycle comprises a driven cover, a deep bid, a free-wheel clutch and an inspection unit.
This driven cover is sheathed on this crank shaft, and driven by this crank shaft and rotate.
This deep bid is sheathed on this crank shaft and contiguous one of them crank.
This free-wheel clutch is sheathed on this crank shaft, and between between this driven cover and this deep bid, and opposite end section connects respectively this driven cover and this deep bid.
This inspection unit is arranged at this driven cover, comprises a strain sensor and a torsion computing module.This strain sensor is exported a reaction signal to this torsion computing module according to the deformation quantity of this driven cover after receiving an initialize signal.This torsion computing module calculates this reaction signal and export a torsion signal to this power-assisted unit.
Preferably, this torque sensor of electric bicycle also comprises one and this deep bid is locked the hold-doun nut that is fixed in this free-wheel clutch.
The utility model beneficial effect is: measure by this strain sensor the deformation that difference that this driven cover is subjected to turning effort between this crank shaft and this free-wheel clutch causes, calculate via this torsion computing module the torsion that imposes on this driven cover again, make the torsion that puts on this crank shaft both sides all can calculate.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Consult Fig. 1, Fig. 2 and Fig. 3, the preferred embodiment of the utility model torque sensor of electric bicycle is applicable to be installed on an Electrical Bicycle.This Electrical Bicycle has the crank 11 that a crank shaft 10 that extends along axis direction, two are arranged at this crank shaft two opposite ends, reaches a power-assisted unit 12(such as Fig. 5 and shows).This torque sensor of electric bicycle comprises a driven cover 2, a deep bid 3, a free-wheel clutch 4, a hold-doun nut 5, and an inspection unit 6.
This driven cover 2 is sheathed on this crank shaft 10, and is subjected to this crank shaft 10 to drive and rotate.
This deep bid 3 is sheathed on this crank shaft 10 and contiguous one of them crank 11.
This free-wheel clutch 4 is sheathed on this crank shaft 10, and between 3 of this driven cover 2 and this deep bids, and opposite end section connects respectively this driven cover 2 and this deep bid 3.
This hold-doun nut 5 locks this deep bid 3 and is fixed in this free-wheel clutch 4 (as shown in Figures 3 and 4).
When described crank 11 is stepped on forward, driving this crank shaft 10 by described crank 11 rotates, the driven cover 2 that driven by this crank shaft 10 and rotate drives this free-wheel clutch 4 and this deep bid 3 rotates, this deep bid 3 is because connecting the formed antagonistic force of overall weight of this Electrical Bicycle of chain-driving, cause this free-wheel clutch 4 and this driven cover 2 of these crank shaft 10 distortions, thereby cause the deformation of this driven cover 2.When described crank 11 was stepped on backward, this free-wheel clutch 4 can break away from this deep bid 3 and not drive this deep bid 3 rotations.
Consult Fig. 2, Fig. 4 and Fig. 5, this inspection unit 6 is arranged at this driven cover 2, comprises a strain sensor 61 and a torsion computing module 62.Deformation quantity output one reaction signal of this strain sensor 61 cover 2 driven according to this after receiving an initialize signal is to this torsion computing module 62.This torsion computing module 62 calculates this reaction signal and export a torsion signal to this power-assisted unit 12, and this power-assisted unit 12 power according to this torsion signal output one correspondence come this Electrical Bicycle of assistive drive.
In sum, this driven cover 2 is subjected to this crank shaft 10 and 4 formed antagonistic forces of overall weight that connect this Electrical Bicycle of chain-driving because of deep bid 3 of this free-wheel clutch to form turning effort difference, and then reverse this driven cover 2 and cause deformation, measure this deformation quantity by this strain sensor 61, calculate via this torsion computing module 62 torsion that imposes on this driven cover 2 again, therefore make the torsion that puts on this crank shaft both sides all can calculate, therefore really can reach the purpose of this utility model.
