Technical field
This utility model belongs to bicycle electric accessory technical field, more particularly to one kind is used for bicycle or auxiliary power
The bilateral energy meter of bicycle.
Background technology
Energy meter at this stage, draws the acting of bicyclist by measuring pedal force, facilitates bicyclist's reasonable distribution body
Power.Generally there is torsion torque sensor to design on crank, or design is on sprocket wheel, all there is complex structure, measurement is inaccurate
The cost of true problem, particularly later stage repacking is very high, troublesome maintenance.
Bicycle crank is the important attachments of a bicycle that stampede power is transferred to trailing wheel, during left crank and right crank pass through
Axle is coupled together, and right crank connects sprocket wheel in addition.In addition axis is installed on vehicle frame by bearing so that two cranks are together with connecting shaft
Can rotate on bicycle rack.
In this utility model, when riding, left and right foot often encloses alternating and exerts oneself bicyclist.When left foot is firmly trampled, ride
The pedal force used by person passes to left axle by left crank, and left axle transmits the force to sprocket wheel, so as to sprocket wheel drives trailing wheel fortune
It is dynamic.When right crus of diaphragm is firmly trampled, pedal force passes to left axle by right axle end, and left axle transmits the force to sprocket wheel, so as to sprocket wheel
Drive rear wheel movement.Therefore, either left foot is trampled or right crus of diaphragm is trampled, and left axle has torsional deformation, and we are left by measuring
The stress distortion of axle, through calculating the bicycle ergometer designed, can accurately measure the power used by bicyclist.
Utility model content
In consideration of it, in order to solve above-mentioned technical problem, the utility model proposes it is a kind of be used for bicycle or auxiliary power from
The bilateral energy meter of driving, simple structure are practical, and can measure the power of right crus of diaphragm output.
In order to solve above-mentioned technical problem, this utility model is employed the following technical solutions：
It is a kind of for bicycle or the bilateral energy meter of motive-force-assisted bicycle, the bilateral energy meter includes foil gauge, letter
Number process transmission circuit, left axle, right axle and fluted disc support, the foil gauge and the signal processing transmission circuit pass through wire phase
Connection；Wherein, the foil gauge is brought into close contact with the left axle, the left crank of the embedded bicycle of the signal processing transmission circuit
Interior, the right axle is inserted inside the left axle, and the end of insertion is fixedly connected with the left axle, the other end of the left axle and institute
State fluted disc support to be fixedly connected.
Further, the outer surface of the left axle is cased with waterproof jacket, and the top of the left axle both sides is provided with the first lid and
Two lids.
Further, first lid and the described second lid push down the waterproof jacket.
Further, the left crank is connected by square shaft with the left axle；Right crank passes through square shaft phase with the right axle
Connection.
Further, the left crank is connected by spline with the left axle；The right crank is with the right axle by flower
Key is connected.
The beneficial effects of the utility model are：Simple structure, it is practical.
1) foil gauge is directly brought into close contact with left axle, and dynamometry is more directly and accurate.
2) signal processing transmission circuit is embedded in left crank, and is connected with foil gauge by wire, will can be strained
The power measured by piece is launched by signal processing transmission circuit, more solid and reliable.
3) left axle is provided with waterproof jacket, can be effectively protected left axle and foil gauge, extends the life-span for using.
4) right axle is inserted in left axle by spline, the power output of right crus of diaphragm, can be transferred to left axle by right axle, so as to answer
Become piece to measure.Therefore, the power of right crus of diaphragm output can also be measured.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and implement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain this
Utility model, is not used to limit this utility model.
As shown in figure 1, it is a kind of for bicycle or the bilateral energy meter of motive-force-assisted bicycle, including foil gauge 10 and letter
Number process transmission circuit 2, foil gauge 10 are connected by wire 12 with signal processing transmission circuit 2；Wherein, foil gauge 10 and a left side
Axle 3 is brought into close contact, and signal processing transmission circuit 2 is embedded in the left crank 1 of bicycle.Inside the insertion left axle 3 of right axle 9, insertion
End is fixedly connected with left axle 3, and the other end socket spline housing 11 of left axle 3, spline housing 11 are fixedly connected with fluted disc support 7.It is left
The outer surface of axle 3 is cased with waterproof jacket 5, and 5 two ends of waterproof jacket are cased with the first lid 4 and the second lid 6, and the first lid 4 is by screw thread and voluntarily
Che Wutong left ends are fixedly connected, and the second lid 6 is fixedly connected with bicycle bottom bracket right-hand member by screw thread, and 3 one end of left axle passes through bearing
