Figure 1A and 1B is stereogram, shows the resistance adjustment device 1 according to one embodiment of the utility model.Fig. 2A and Fig. 2 B
For vertical view and side view, in the embodiment in figure 1, resistance adjustment device 1 is used in fitness equipment (not shown) turn for display
Driving wheel 2, to apply resistance in rotating wheel 2.In some embodiments, rotating wheel 2 can be flywheel, and fitness equipment can be any
Equipment with rotating wheel 2, for example, flywheel bicycle, elliptical machine, recumbent cycle etc..
As shown in Figure 1A and 1B, the main element of resistance adjustment device 1 includes fixed mechanism 10, rotating mechanism 11, motor
12, screw rod 13, nut 14, connecting seat 17.
As shown in Figure 1A and 1B, fixed mechanism 10 is for being fixed with fitness equipment.In the present embodiment, fixed mechanism can be
The structure of similar T shapes, for example, the T-shaped structure being made of first structure 101 and the second structure 103, and pass through two fixed members
Part 102, such as screw, are fixed on fitness equipment.As shown in Fig. 2A and 2B, rotating mechanism 11 can be by two same shapes
Plate 110 is constituted.Wherein, the madial wall of each plate 110 is respectively provided with multiple magnet 112.Two adjacent magnets in same plate 110
112 polarity is on the contrary, also that is, one is the poles N, another is the poles S.Two magnet of identical corresponding position on different plates 110
112 polarity is also opposite.Rotating wheel 2 may include metal part 22, and the periphery of metal part can have that there are one non-magnetic rings
21, such as aluminium ring, but rotating wheel 2 is not limited to above structure.Whereby when magnet 112 is close to rotating wheel 2, resistance is generated.When more
A magnet 112 is closer to rotating wheel 2, then resistance is bigger.
As shown in Figure 1A and 1B, nut 14 is articulated in pivoting point 142 on fixed mechanism 10.The second end 132 of screw rod 13

Amount.After a measurement, torsion machine can be removed.In this way, the number of turns that can be rotated by screw rod 13, is converted into Resistance Value, and it is shown in strong
On the display panel of body equipment.Can be very small, for example, 0.0001 circle due to the unit that screw rod 13 rotates；In this way, when making
User inputs instruction, for example, when instructing rotating wheel 2 to be adjusted to some Resistance Value by display panel input, circuit board or control
Circuit board 151 processed is adjusted after can the Resistance Value being converted into corresponding rotating cycle.By aforesaid way, it can accomplish nothing
Segmentation, accurate draught control.
As shown in Fig. 3 A and 3B, in another embodiment, motor 12 is moved to " most with screw rod 13 in " minimum drag position "
It is distinguished into a certain number of grades, such as 20 grades between big resistance positions ", and when producing fitness equipment, is surveyed with torsion machine
Measure motor 12 and screw rod 13 the rank position (including maximum resistance position) and rotating wheel 2 under different rotating speeds (such as
30rpm, 60rpm, 90rpm, 100rpm, 120rpm) resistance.Since the number of turns of rotary screw 13 required for the grade is
It is fixed, therefore, it can be adjusted according to the resistance grade of user's demand.
