Abstract
The invention discloses a measuring device for power of a bicycle. The measuring device for the power of the bicycle comprises torsion sensors and a microprocessor chip, wherein one end, fixed to a middle shaft, of a crank extends to form a shaft sleeve, the middle shaft is sleeved with the shaft sleeve, a gap is reserved between the shaft sleeve and the middle shaft, installing positions are arranged on the shaft sleeve, the torsion sensors are fixed to the installing positions, and are connected with the microprocessor chip, the number of the installing positions is four, each torsion sensor is fixed to each installing position, the four torsion sensors are connected in series to form a Wheatstone bridge, the Wheatstone bridge is connected with the microprocessor chip, and the torsion sensors and the microprocessor chip are arranged in a separated mode. The measuring device for the power of the bicycle is convenient to install, maintain and replace, more stable in signal sensing, and more accurate in measurement, and cost is reduced.
Description
Technical field
The present invention relates to the technical field of bicycle, particularly a kind of Cycle Power determinator.
Background technology
In prior art, on bicycle, the mounting structure of power measurement device is roughly such: on the sprocket terminal pad (claiming again spider element) of bicycle, offer mounting groove, the torque sensor of power measurement device and micro-chip processor are directly installed in the mounting groove of sprocket terminal pad, micro-chip processor obtains the torque information of riding and carries out the data processing from torque sensor, then power signal is sent to display device and is shown, measure thus cycling power.This structure, because will on the sprocket terminal pad, offer mounting groove, makes the installing space of sprocket terminal pad limited, and 2 sprocket gear can only be installed on the sprocket terminal pad, causes the bicycle shift gear to reduce.
The bicycle also had is to offer mounting groove on crank, the torque sensor of power measurement device and micro-chip processor are arranged in the mounting groove of crank, micro-chip processor obtains the torque information of riding and carries out the data processing from torque sensor equally, then power signal is sent to display device and is shown, measure thus cycling power.But, offer mounting groove and to offer mounting groove on the sprocket terminal pad the same on crank, be all torque sensor to be integrated in together with micro-chip processor on crank or sprocket terminal pad, if there is fault, can only change crank and sprocket terminal pad, use replacement cost high, inconvenient maintenance maintenance.
In view of this, the inventor has researched and developed a kind of new bicycle power measurement device specially, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of Cycle Power determinator, to facilitate installation.
Another object of the present invention is to provide a kind of Cycle Power determinator, with easy maintenance and replacement, reduce costs.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of Cycle Power determinator, comprise torsion torque sensor and micro-chip processor, stiff end at crank and axis extends to form axle sleeve, axle sleeve be nested with on axis and and axis between retention gap, axle sleeve is provided with installation position, torsion torque sensor is fixed on installation position, and torsion torque sensor is connected with micro-chip processor.
Described installation position has four, fixes respectively a torsion torque sensor in four installation positions, and four torsion torque sensors are composed in series resistance bridge, and resistance bridge is connected with micro-chip processor.
Described installation position is to form groove on axle sleeve, and torsion torque sensor is fixed on groove and encapsulates with fluid sealant.
The sprocket terminal pad is installed on the axle sleeve of described crank, and between sprocket terminal pad and axle sleeve, retention gap forms installation position, and torsion torque sensor is fixed on this installation position and encapsulates with fluid sealant.
Described torsion torque sensor and micro-chip processor divide and are arranged.
Form the wire guide be communicated with installation position on described crank, the wire that connects torsion torque sensor and micro-chip processor is set in wire guide.
Described micro-chip processor is arranged on crank or other appropriate locations of bicycle.
Described micro-chip processor directly or be connected with display device by emitting/receiving.
After adopting such scheme, the present invention is simple in structure, compared with prior art, has following advantage:
One, because torsion torque sensor is fixed on axle sleeve, axle sleeve and axis retention gap can produce torsion, can accurately record thus the torsion produced while riding, convert and draw the power of riding by micro-chip processor again, mounting structure does not affect the installing space of sprocket terminal pad, has eliminated the restriction to the design of sprocket terminal pad, makes the sprocket terminal pad that more sprocket gear can be installed, easy for installation, the bicycle shift gear increases;
Two, adopt resistance bridge to measure torsion, transducing signal is more stable, and it is more accurate to measure;
Three, torsion torque sensor and micro-chip processor divide and are arranged, and when one of them member damages, can be changed respectively, and easy maintenance and replacement, reduce costs.
Below in conjunction with drawings and the specific embodiments, the present invention is described in further details.
The accompanying drawing explanation
Fig. 1 is three-dimensional exploded view of the present invention;
Fig. 2 is combined amplifier figure of the present invention.
Label declaration
Embodiment
As shown in Figure 1, be a kind of Cycle Power determinator that the present invention discloses, comprise torsion torque sensor 10 and micro-chip processor (common member, not shown).
Extend to form axle sleeve 11 at crank 1 and the stiff end of axis 2, axle sleeve 11 is nested with on axis 2, axle sleeve 11 and and axis 2 between retention gap, make axle sleeve 11 and axis 2 can produce torsion.
These are only specific embodiments of the invention, is not the restriction to protection scope of the present invention.All equivalent variations of doing according to the mentality of designing of this case, all fall into the protection domain of this case.
