Description
Technical field
The utility model 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 data processing from torque sensor, then power signal is sent to display device and shows, measure thus cycling power.This structure, because will offer mounting groove on sprocket terminal pad, makes the installing space of sprocket terminal pad limited, and 2 sprocket gear can only be installed on sprocket terminal pad, causes bicycle shift gear to reduce.
Also the bicycle having is on crank, to offer mounting groove, 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 data processing from torque sensor equally, then power signal is sent to display device and shows, measure thus cycling power.But, on crank, offer mounting groove and on sprocket terminal pad, to offer mounting groove the same, 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.
Utility model content
The purpose of this utility model is to provide a kind of Cycle Power determinator, to facilitate installation.
Another object of the present utility model is to provide a kind of Cycle Power determinator, with easy maintenance and replacement, reduces costs.
To achieve these goals, the technical solution of the utility model 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 on axle sleeve, to form groove, and torsion torque sensor is fixed on groove and encapsulates with fluid sealant.
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.
On described crank, form the wire guide being communicated with installation position, 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.
Adopt after such scheme, the utility model 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 producing while riding, by micro-chip processor, convert and draw the power of riding 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 sprocket terminal pad that more sprocket gear can be installed, easy for installation, 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 change respectively, and easy maintenance and replacement, reduces costs.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is three-dimensional exploded view of the present utility model;
Fig. 2 is combined amplifier figure of the present utility model.
Label declaration
Torsion torque sensor 10, crank 1, axle sleeve 11, installation position 12, wire guide 13, axis 2, sprocket terminal pad 3, wire 4.
Embodiment
As shown in Figure 1, be a kind of Cycle Power determinator that the utility model discloses, comprise torsion torque sensor 10 and micro-chip processor (common member, not shown).
At crank 1 and the stiff end of axis 2, extend to form axle sleeve 11, 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.
Axle sleeve 11 is provided with installation position 12.Installation position 12 can be on axle sleeve 11, directly to form groove, also can as shown in the figure sprocket terminal pad 3 be installed on axle sleeve 11, and between sprocket terminal pad 3 and axle sleeve 11, retention gap forms installation position 12.
Torsion torque sensor 10 is fixed on installation position 12, has eliminated the restriction to 3 designs of sprocket terminal pad, makes sprocket terminal pad 3 that more sprocket gear can be installed, easy for installation, and bicycle shift gear increases.Torsion torque sensor 10 is connected with micro-chip processor.For groove installation position 12, torsion torque sensor 10 is fixed on groove and encapsulates with fluid sealant.For the gap between sprocket terminal pad 3 and axle sleeve 11, torsion torque sensor 10 is to be fixed in this gap installation position 12 and with fluid sealant to encapsulate.Installation position 12 can have four, fixes respectively 10, four torsion torque sensors 10 of a torsion torque sensor and be composed in series resistance bridge in four installation positions 12, and resistance bridge is connected with micro-chip processor 2, and transducing signal is more stable, and it is more accurate to measure.If allowed, the utility model also can be used five or six torsion torque sensors 10, does not illustrate herein.
