Exercise bike magnetic brake brake linkage structure improvement

This creation department is about the technical field of fitness equipment, especially the mechanical change of magnetoresistance into load information, so as to facilitate the reader to read the improvement of the structure of the magnetron brake linkage of the exercise bike.

Press, the exercise bike is mainly used to achieve the effect of fitness by turning a flywheel (resistance wheel).

However, the flywheel of the conventional exercise bike must generate a predetermined resistance value by a resistance unit, and the resistance unit is currently roughly divided into two categories; one is a contact type resistance unit, and the other is a magnetoresistive type resistance unit. Among them, the contact type resistance unit mainly adjusts the resistance of the flywheel by the force of contact with the flywheel, and of course, also uses the contact to achieve the braking effect, but since the contact type resistance unit is prone to wear, there is a cost burden of additional consumables. .

The reluctance type resistance unit uses magnetic force to generate suction force between the flywheel and the resistance of the user to step on. The conventional reluctance type resistance unit is mainly composed of an adjustment mechanism and a reluctance device (for example, In the prior art of the Chinese Patent Publication No. M374886, the magnetoresistive device is used to generate a magnetic force to cause resistance to the rotation of the flywheel, and the adjustment mechanism is coupled to the magnetoresistive device. It is used to adjust the position of the magnetoresistive device relative to the flywheel to change the magnitude of the resistance.

However, the above adjustment mechanism mainly uses mechanical actuation to change the preset position of the magnetoresistive device relative to the flywheel. Therefore, the conventional adjustment mechanism cannot respond to the magnitude of the magnetic resistance of the magnetoresistive device applied to the flywheel, so that the user must continuously adjust the transmission. In order to meet their own needs, in addition to causing inconvenience in use, because the load set by the current training (that is, the magnitude of the magnetoresistance of the magnetoresistive device to the flywheel) cannot be known, causing the same user to train for the next time. At the same time, it is still necessary to adjust to the "feelingly equivalent" load one by one, and there is no systematic need to reach a stepwise training demand.

In view of the above problems and shortcomings of the prior art, one of the aims of the present invention is to provide an improved structure of the magnetron brake linkage structure of the exercise bicycle. By structural design, the mechanical actuation changes are converted and formed into a visual signal. It is convenient for the user to quickly know the value of the current load (that is, the magnitude of the magnetoresistance of the magnetoresistive device applied to the flywheel), which greatly shortens the adjustment time of the user each time.

According to the above object of the present invention, an improved structure of a magnetron brake linkage structure of an exercise bike is provided, which includes: an exercise bike and a linkage mechanism disposed on the exercise bike. The exercise bike includes a frame, a seat, a flywheel, a pedaling device, a magnetoresistive device, and an adjustment mechanism. The linkage mechanism includes a display panel, a load conversion unit electrically connected to the display panel, and a connecting rod connecting the magnetoresistive device and the load conversion unit. In the process of driving the magnetoresistive device by the adjusting mechanism, the interlocking mechanism is synchronously triggered to display the magnetic resistance of the magnetoresistive device applied to the flywheel, so that the user can visually understand the exercise bike. Under load information.

The load converting unit 22 includes a potentiometer 221 connected to the connecting rod 23 and a converting circuit 222 electrically connected to the potentiometer 221 . The potentiometer 221 is a standard component having an adjustment knob 223; the rod 23 is displaced by the synchronous traction adjustment knob 223 to trigger the potentiometer 221 to output a different potential (resistance) signal to the conversion circuit 222. The conversion circuit 222 changes the potential (resistance) signal outputted by the potentiometer 221, and converts the magnitude of the resistance of the magnetoresistive device to the flywheel, that is, the data value of the load value (resistance value), and transmits it to the display panel 21 for display. In implementation, the potentiometer 221 is selected from linear sliding potentiometers ("faders").
