The first plate 142 has four openings 142a, and the magnetic members 18 are respectively disposed in the openings 142a. In the embodiment, the first plate body 142 is made of a magnetic material, and the second plate body 144 is made of a magnetic conductive material. Therefore, the first plate body 142 is magnetically attached to the second plate body 142. After 144, the magnetic members 18 are magnetically attached to the second plate 144 corresponding to the openings 142a. In addition, the materials for manufacturing the first plate body 142 and the second plate body 144 may be mutually adjusted, and are not limited to the above examples.

As shown in FIG. 2 and FIG. 4 , the sleeve 20 is disposed on the frame 210 . The sleeve 20 is a hollow body with two ends, and includes an outer tube 22 and a collar 23 as an example. The fixing member and an inner tube 24. The outer tube 22 is disposed on the main shaft tube 212 and has a side opening 22a; the collar 23 is fixed to the inner wall of the outer tube 22; the inner tube 24 is passed through the collar 23 to The upper and lower movable manners are disposed in the outer tube 22, and the bottom end of the inner tube 24 is provided with a bolt 25 as an example. In addition, the outer tube surface of the inner tube 24 is sleeved with a spring 26 as an example. The elastic member has one end of the spring 26 abutting against the collar 23, and the other end of the spring 26 abuts the portion of the bolt 25 exposed to the inner tube 24, thereby indirectly passing the inner tube 24 through the bolt 25.

The magnetron mechanism 30 includes an adjustment line 32 and a turntable 34. The adjusting wire 32 is disposed in the outer tube 22 and the inner tube 24, and the one end is connected to the rotating wheel 34, and the other end is opposite to the plate body 14 and the lug 15 is pivotally connected to the other end of the front fork tube 214. The turntable 34 is disposed at the top port of the outer tube 22. Therefore, by rotating the turntable 34 in the forward/reverse direction, the user can retract or release the adjustment line 32, and the board 14 is pivoted between the first position and the second position. As shown in Figure 5, when the adjustment line is rolled up After the 32, the plate body 14 is in a first position away from the flywheel 220. At this time, the magnetic members 18 are far away from the flywheel 220, and the magnetic damping force between them is small. Therefore, the user When the pedal 200 is stepped on the exercise bike 200, the resistance is small. As shown in FIG. 6, when the adjustment line 32 is released, the plate body 14 is moved to a second position close to the flywheel 220. At this time, the magnetic members 18 are closer to the flywheel 220, and are in close proximity to each other. The magnetic damping force is large, and therefore, the resistance experienced by the user when pedaling the pedal 230 is large. Therefore, the user can adjust the distance between the plate body 14 and the flywheel 220 according to the required riding experience.

It is worth mentioning that when the plate 14 is swung to the second position, the block 16 will abut against the bottom of the pivot 215 on the front fork tube 214, and the plate 14 faces the flywheel 220. When pivoting, the swing cannot exceed the second position and can only be maintained at most at the second position. In this way, by setting the lower limit of the range of the pivotal amplitude of the plate body 14, the exercise bike 200 can be provided with a good safety mechanism, and the plate body 14 or the plate can be prevented from being over-adjusted by the user or other occasional factors. The magnetic member 18 on the body 14 is in direct contact with the flywheel 220, thereby eliminating direct contact wear and damage, and further improving the durability of the exercise bicycle 200.

Please refer to FIG. 1 , FIG. 2 and FIG. 4 , the brake mechanism 40 includes a brake grip 42 , a brake member 44 and a brake line 46 . The brake grip 42 is pivotally connected to a bracket 213 of the spindle tube 212, and one end protrudes from the side opening 22a of the outer tube 22 into the outer tube 22, and is connected to the inner tube 24; In this embodiment, the brake arm member 44 is exemplified by a brake clamp arm, and the brake clamp arm is fixed on the bracket 217 of the bottom tube 216, and the clamp arms respectively protrude to the two sides of the flywheel 220 for clamping. The flywheel 220 is used to generate a brake for the flywheel 220, wherein the brake clamp arm is a commonly used structure in the industry, and will not be described herein; the brake wire 46 is disposed along the spindle tube 212 and the bottom tube 216, and one end thereof is Passing through the outer tube 22 and with the inner tube 24 The bottom end is connected and the other end is connected to the brake clamp arm.

Thereby, the user can control the braking of the brake arm by controlling the brake grip 42 to swing. That is, when the brake grip 42 is depressed, the brake grip 42 protrudes to one end of the outer tube 22 that is connected to the inner tube 24, and the inner tube 24 is lifted and tightened to be connected to one end of the inner tube 24. The brake line 46 moves the brake clamp arm through the brake line to cause the brake carriage arm to generate a brake on the flywheel 220. When the user releases the brake grip 42, the spring force of the spring 26 pushes the inner tube down to be reset, thereby releasing the brake line 46, so that the brake gripper arm does not generate a brake on the flywheel 220.

It is worth mentioning that the design of the adjusting line 32 of the magnetron 30 and the braking line 46 of the braking mechanism 40 are uniformly inserted into the sleeve 20, thereby effectively integrating the wires of the mechanisms, so that the exercise bicycle 200 is The appearance is simple and beautiful.

Furthermore, when it is desired to remove the magnetic members 18 for maintenance or repair, since the magnetic force is inversely proportional to the cube of the distance, if it is to be directly oriented in the direction perpendicular to the plate 14, The removal of the magnetic member 18 is quite difficult. The combination of the first plate body 142 and the second plate body 144 is advantageous in that the first plate body 142 can be pulled out in the direction of the horizontal plate body 14, and the magnetic members are further 18 is separated from the second plate body 144, and has the effect of labor saving.

In addition, in other embodiments, the number of the magnetic member 18 and the opening 142a may be one or more, and is not limited to the number of the above embodiments.
