Please refer to FIG. 1 , which shows a first embodiment of the fitness training device provided by the present invention, which comprises a base frame 1 standing on the ground, and the base frame 1 is formed into a structure similar to a bicycle frame. A grip 11 is provided at the front end thereof, and a seat 12 is provided at the rear end for the user to sit on the seat 12 and control the grip 11 by hand; wherein the seat 12 is provided with a sleeve 121 The pedestal 1 is adjustable in position relative to the pedestal 1 , and the grip 11 is also disposed in the pedestal 1 by a sleeve 111 and can be adjusted to be positioned on the pedestal 1 The relative position, whereby the height of the grip 11 and the seat 12 relative to the base frame 1 can be adjusted corresponding to the user's body.

The crank frame 1 is pivotally disposed below the seat 12 with a crank gear 2, and the crank gear 2 is provided with a first transmission portion 21, and the first transmission portion 21 includes a plurality of transmission members of different sizes and concentrically arranged. And a pedal 22 is provided on both sides of the crank sprocket 2 for the user to step on and rotate. In the embodiment, the transmission member is a plurality of gears 23 of different sizes, and the gears 23 are concentrically disposed on the crank gear plate 2. The rear end of the base frame 1 is further provided with a rotating wheel 3, and a shaft of the rotating wheel 3 is provided with a second transmission portion 31. The second transmission portion 31 is provided with a plurality of transmission members of different sizes and concentrically arranged; The transmission member is also the gear 32 in this embodiment. The first transmission portion 21 is connected to the second transmission portion 31 by a first connecting member. In the embodiment, the first connecting member is a chain wound around the gears 23, 32 of the two transmission portions 21, 31. 4, in order to drive the wheel 3 to rotate; in detail, the user drives the crank disk 2 to rotate by stepping on the pedal 22, and by the gear 23 of the first transmission portion 21 and the chain 4, The second transmission portion 31 rotates to drive the reel 3. The above-mentioned chain 4 is wound around one of the two transmission portions 21, 31, and the connected gear can be switched by a switching device. This switching device is commonly known as a transmission 5, which can switch the chain 4 to gears of different sizes, thereby changing the force by which the user steps on the driving wheel 3.

The runner 3 is subjected to a resistance device and encounters resistance when rotating. The resistance device is disposed on the pedestal 1 near the runner 3 to provide resistance to the runner 3. In the embodiment, the resistance device generates resistance by using the principle of magnetic brake; in detail, the runner 3 is made of a metal material, and the resistance device is a magnetic block 6 pivoted on the base frame 1. ,its The magnet block 6 is close to the runner 3 but is not in contact with the runner 3. When the rotating wheel 3 rotates, the rotating wheel 3 is induced by the magnetic field of the magnetic block 6 to induce an eddy current, and the eddy current further generates a magnetic force opposite to the rotating direction of the rotating wheel 3, thereby forming the rotating wheel 3 to rotate. Resistance, and the magnitude of this resistance depends on the rotational speed of the reel 3 and the distance between the magnet block 6 and the reel 3. Therefore, when the user increases the rotational speed of the runner 3 by stepping on, the resistance value will increase; on the other hand, if the distance between the magnet block 6 and the runner 3 is reduced, the resistance value will also increase. In this embodiment, a controller 13 is disposed at the grip 11 and electrically connected to the magnetic block 6. The magnetic block 6 can be pivoted on the base frame 1 as shown in FIGS. 2 and 3. In order to change the distance between the wheel and the wheel 3, the purpose of adjusting the resistance is achieved.

With the fitness training device of the present invention, the resistance device can be firstly used to generate the resistance to the runner 3, and the user can overcome the force required to step on the pedal 22, thereby achieving the training effect; and simultaneously by the magnetic block 6 and The adjustment of the distance between the runners 3 changes the magnitude of the resistance for the user to achieve different levels of training. So far, the part is the resistance of the runner 3, but the user can change the force of the pedaling through the transmission 5 in the present creation. Therefore, the training device of the present invention has two ways of changing the user's pedaling force, one is to change the resistance of the runner 3, and the other is to control the transmission 5 to switch the gear connected to the chain 4. In this case, the creation is similar to riding a real bicycle, and the occasion of increasing the resistance of the runner 3 can be compared to riding the bicycle uphill. At this time, the user must pay more force to overcome the resistance; The user can also switch the gear connected to the chain 4 through the transmission 5, thereby reducing the force required to step on the pedal 22. The other side A brake device 7 is disposed on the runner 3, and the brake device 7 is provided with a controller 71 on the grip 11, whereby the user can reduce the rotational speed of the runner 3. Overall, this creation can provide a variety of variability in the training process, more comparable to the real state of the ride to enrich the fun, avoiding the tedious repetition of the same action during the training process.

The fourth embodiment to the sixth embodiment is the second embodiment of the present invention. The main difference between the embodiment and the first embodiment is that a shaft hole 24 is disposed at the center of the crank gear 2, and The shaft hole 24 is pivotally provided with a rotating member 25, and a pivot hole 251 is disposed on the rotating member 25 at a distance from the center thereof (such as the distance D in FIG. 7), and a pivot hole 251 is disposed at the pivot hole 251. The connecting rod 26 has two ends of the connecting rod 26 connected to the crank 27 of the crank toothed disc 2, respectively. In addition, the base frame 1 is provided with a rotatable flywheel 8, wherein the flywheel 8 and the reel 3 are in contact with each other by a tread, and the flywheel 8 is rotated by the reel 3, and the flywheel 8 is The two connecting members are connected to the rotating member 25. In the embodiment, the second connecting member is a belt 81 wound around the flywheel 8 and the rotating member 25, so as to drive the rotating member 25 to rotate.

With the configuration of the above-mentioned members, in the embodiment, when the pedal is stepped on, the crank toothed disc 2 is rotated by the crank 27, and the rotating wheel 3 is rotated by the chain 4; and since the rotating wheel 3 is in contact with the flywheel 8, the flywheel 8 is also The belt is rotated, and the rotating member 25 is rotated by the belt 81. Moreover, since the position of the connecting rod 26 connecting the crank 27 and the pedal is not located at the center of rotation C of the rotating member 25, when the rotating member 25 rotates, as shown in FIG. 7, the position of the connecting rod 26 also changes. Form a circle with a radius D The trajectory is such that the connecting rod 26 forms a maximum distance of 2D at each position. Therefore, for the user, stepping on the pedal will generate a slight vibration up and down, and can simulate the riding feeling when the road condition is not good.

In addition, in this embodiment, the flywheel 8 can be controlled to leave the reel. The prior art has many specific methods for controlling the movement of the flywheel, such as using a high tension rope to pull it apart, etc. Detailed. When the flywheel leaves the runner, the aforementioned slight vibration during riding is no longer generated, and a smooth riding feel is restored.

However, the disclosure of the above embodiments is intended to illustrate the present invention and is not intended to limit the present invention, so the replacement of equivalent elements should still be within the scope of this creation.

In summary, it can be made clear to the skilled person that the creation can achieve the aforementioned objectives, and it has already met the requirements of the Patent Law and submitted an application according to law.
