Specific embodiment
Please referring initially to Fig. 1, fitness equipment shown in figure includes that a vehicle frame 12 and one is rotatably arranged in vehicle frame 12
Flywheel 14.Resistance sensing mechanism 10 of the invention includes a resistance adjustment unit 30 and a sensing unit 40.
Resistance adjustment unit 30 adjusts bar with the opposite magnetic part 32 of an adjusting seat 31, two, a fixed sleeving 33, one
34 and a nut 35.Adjusting seat 31 is located at the periphery of flywheel 14 and the rear end of adjusting seat 31 is hubbed at vehicle frame 12, adjusting seat 31
Two relative side extended through a strip hole 312；Magnetic part 32 is set to the medial surface of adjusting seat 31 and flywheel can be passed through
Between two magnetic parts 32；Fixed sleeving 33 is fixed on vehicle frame 12 and is located at the top of adjusting seat 31；Adjusting bar 34 has a rotation
The threaded shank 344 that button 342 connect knob 342 with one, threaded shank 344 can original place be rotationally arranged in fixed sleeving 33；Nut
35 spiral shells are set to the threaded shank 344 of adjustment bar 34, are hubbed at moreover, the two relative side of nut 35 passes through one first pivot P1 respectively
Adjusting seat 31, the first pivot P1 are displaceably arranged in the strip hole 312 of adjusting seat 31.
Sensing unit 40 has a first connecting rod seat 41 and a second connecting rod seat 42, one end of first connecting rod seat 41 and second
One end of connecting rod base 42 is mutually articulated by two the second opposite pivot P2, and the other end of first connecting rod seat 41 passes through the
One pivot P1 is hubbed at the nut 35 of resistance adjustment unit 30, and the other end of second connecting rod seat 42 passes through two opposite third pivots
P3 is hubbed at the fixed sleeving 33 of resistance adjustment unit 30.In addition, sensing unit 40 also there is a sensing element 43 to be felt with one
Element 44 is surveyed, sensing element 43 is set to one of position of the top surface of first connecting rod seat 41 and the bottom surface of second connecting rod seat 42
It sets, sensed element 44 is set to another position of the top surface of first connecting rod seat 41 and the bottom surface of second connecting rod seat 42,
That is if sensing element 43 is the top surface that first connecting rod seat 41 is arranged in, it is sensed element 44 and is just arranged in second connecting rod
The bottom surface of seat 42 is sensed element 44 and is arranged in first connecting rod if the bottom surface of second connecting rod seat 42 is arranged in sensing element 43
The top surface of seat 41, no matter however be arranged in a manner of which kind of by aforementioned, had between sensing element 43 and sensed element 44 mutually
It is corresponding.
It can be seen from the above, as shown in Figures 2 and 3, when using the rotation adjustment bar 34 of knob 342, adjustment bar 34 can be via
Threaded shank 344 drives nut 35 on the one hand can band during nut 35 is displaced along the axial upper and lower displacement of adjustment bar 34
The opposite flywheel 14 of dynamic adjusting seat 31 deflects, and enables adjusting seat 31 when opposite flywheel 14 is deflected using between two magnetic parts 32
Magnetic flux change provides drag effect to flywheel 14.On the other hand, nut 35 can drive first connecting rod simultaneously in displacement process
Seat 41, first connecting rod seat 41 at this time can interlock second connecting rod seat 42 again, keep the first, second connecting rod base 41,42 close to each other or
It is separate, in this way, i.e. using the gearing of the first, second connecting rod base 41,42 between sensing element 43 and sensed element 44
Relationship is come the relative distance between changing, once distance between the two changes, sensing element 43 just can generate phase
Corresponding sensing signal just can learn resistance according to the information shown by control panel to a control panel (as shown in the figure), user
The variation of power.
In conclusion resistance sensing mechanism 20 of the invention makes to sense using the configuration of the first, second connecting rod base 41,42
Element 43 and sensed element 44 can be simultaneously towards each other close to or far from not only folk prescriptions when resistance changes
Movement, thus compared with prior art under, the present invention can effectively reach reduce actuating length and shorten sensing the time effect
Fruit.
