The present invention relates to a fitness equipment, and more particularly to an improved magnetoresistance adjustment device of fitness equipment.
General gymnasiums are equipped with fitness equipment, among the equipment, for example, exercise bike is used in the same way as a bicycle. A user can achieve the purpose of exercise by pedaling on the pedals of the exercise bike.
Fan blades are arranged on the resistance wheel of a general windage type exercise bike, with the windage generated by the fan blades, the user must pedal on the pedals of the exercise bike with a larger force. When the exercise bike is used by a user with stronger or weaker pedaling force, the windage generated by the fan blades is often insufficient, resulting in the user being unable to get enough exercise; or if the speed is not fast enough, it is difficult to produce a corresponding windage, and the fitness effect cannot be achieved.
A general non-windage type exercise bike on the market is disposed with a metal ring 11 and a magnetoresistive device 12 on a resistance wheel 10, as shown in
When in use, the user makes the magnetoresistive device 12 to pivot so that the magnetoresistive units 121 on the magnetoresistive device 12 and the metal ring 11 generate a resistance vortex. When the magnetoresistive device 12 is pivoted to different angles, a quantity of the magnetoresistive units 121 of the magnetoresistive device 12 corresponding to the metal ring 11 is different, so that the magnetoresistance generated is different.
However, an angle of rotation of the magnetoresistive device 12 and a resulted magnitude of magnetoresistance are not a simple linear relationship. When the user moves the magnetoresistive device 12 to different angles, it is necessary to go through the method of trial and error to find an angle at which the magnetoresistive device 12 causes a maximum magnetoresistance, resulting in the user must spend time adjusting the magnetoresistance.
In view of this, the present invention provides an improved magnetoresistance adjustment device of fitness equipment, so that the magnetoresistance of a magnetoresistance adjustment device of the general fitness equipment can be directly predicted without using the method of trial and error.
An object of the present invention is to solve the drawback that the magnetoresistance adjustment device of prior art exercise bikes cannot predict a magnitude of magnetoresistance.

Referring to
The magnetoresistive ring 30 is mounted on the mounting surface 211 and corresponds to a position of a peripheral edge of the mounting surface 211.
The fixing member 40 is fixedly mounted on the axle 22, and the fixing member 40 is disposed with at least one positioning bolt 41.
In this embodiment, the fixing member 40 is further protrudingly disposed with a traction portion 42 thereon, and the traction portion 42 is disposed with a traction hole 421 thereon.
A quantity of the positioning bolt 41 is three, and each of the positioning bolts 41 is a screw that is locked to the fixing member 40.
The displacement member 50 capable of displacing relatively along a displacement direction Y is mounted on the fixing member 40 (the circle center extends to a circumference). The displacement member 50 has at least one displacement hole 51, a fixing portion 52 and a magnetoresistive portion 53. A quantity of the displacement hole 51 is the same as a quantity of the positioning bolt 41. The displacement hole 51 allows the positioning bolt 41 to pass through, so that the displacement member 50 can be repeatedly displaced along the displacement direction Y to bring the magnetoresistive portion 53 closer to or away from the magnetoresistive ring 30.
In this embodiment, the magnetoresistive ring 30 is located between the displacement member 50 and the wheel 21.
The displacement member 50 has an attaching surface 501 and a sliding surface 502. The attaching surface 501 is attached to the fixing member 40, and the sliding surface 502 is a surface opposite to the attaching surface 501. The displacement hole 51 penetrates through the attaching surface 501 and the sliding surface 502, and a quantity of the displacement hole 51 is three.
Referring to
The displacement member 50 is further disposed with a fixing bolt 54, and the fixing bolt 54 is mounted on the sliding surface 502.
The magnetoresistive portion 53 is located at one end of the displacement member 50 away from the axle 22, and the magnetoresistive portion 53 is disposed with a plurality of magnetoresistive units 531 in the form of magnets. The magnets 531 are arranged in a shape corresponding to an extending shape of the magnetoresistive ring 30. In this embodiment, the magnetoresistive portion 53 is arcuate.
One end of the traction rope 60 is mounted on the fitness equipment 20, and another end is connected to the fixing portion 52 for driving the fixing portion 52.
In this embodiment, the traction rope 60 is further connected to an adjusting member 61. The adjusting member 61 is mounted on the fitness equipment 20, one of the ends of the traction rope 60 is connected to the fixing portion 52 for driving the fixing portion 52, and the other end is connected to the adjusting member 61 and is driven by the adjusting member 61.
One of the ends of the traction rope 60 is connected to the adjustment member 61 and is driven by the adjusting member 61, and the other end passes through the traction hole 421 and is fixed to the fixing portion 52.
The elastic member 70 has a first end 71 and a second end 72. The first end 71 is fixedly mounted on the positioning bolt 41, and the second end 72 is fixedly mounted on the displacement member 50.
In this embodiment, the second end 72 of the elastic member 70 is mounted on the fixing bolt 54, and the elastic member 70 provides an elastic restoring force so that the displacement member 50 can move along the displacement direction Y.
The present invention has a maximum resistance state A and a disengagement state B.
Referring to
Referring to
The above is the structural configuration and its connection relationship of the present invention. The method of usage of the present invention is as follows, and please refer to
When the user wants to change the resistance, the adjusting member 61 must be pushed to cause the adjusting member 61 to drive the traction rope 60, so that the traction rope 60 drives the displacement member 50 to enable the displacement member 50 to move along the displacement direction Y.
When the user adjusts to the maximum resistance state A, the elastic member 70 can push the displacement member 50 along the displacement direction Y toward the magnetoresistive ring 30, and the positioning bolt 41 at the high end 511 of the displacement hole 51 enables a maximum magnetoresistive vortex generated between the magnetoresistive portion 53 and the magnetoresistive ring 30, thereby further providing the wheel 21 with a larger resistance.
When the user wants to adjust from the maximum resistance state A to the disengagement state B, the user pulls the adjusting member 61 to cause the adjusting member 61 to drive the traction rope 60, thereby allowing the traction rope 60 to move the displacement member 50 along the displacement direction Y toward the axle 22. The magnetoresistive portion 53 gradually moves away from the magnetoresistive ring 30 during the movement, so that the magnetoresistive vortex caused by the magnetoresistive portion 53 to the magnetoresistive ring 30 is gradually weakened, until the positioning bolt 41 is at the lower end 512 of the displacement hole 51, that is, in the disengagement state B, the magnetoresistive portion 53 does not have a magnetoresistive vortex generated between itself and the magnetoresistive ring 30, thereby preventing the wheel 21 from being affected by resistance.
Since the displacement member 50 can be repeatedly displaced along the displacement direction Y, when in the disengagement state B, the magnetoresistance portion 53 is completely disengaged from the magnetoresistive ring 30. When in the maximum resistance state A, the magnetoresistance portion 53 corresponds entirely to the magnetoresistive ring 30, thus the difference between a maximum resistance value and a minimum resistance value that can be caused by the present invention is large.
Thereby, the present invention can solve the drawback that the magnetoresistance adjustment device of the prior art fitness equipment 20 cannot predict a magnitude of magnetoresistance generated, that is, a magnitude of resistance value of adjustment can be foreseen.
In summary, the above embodiments and drawings are merely the preferred embodiments of the present invention, and the scope of implementation of the present invention is not limited thereto. In other words, all the equivalent changes and modifications made according to the appended claims shall still fall within the scope covered by the appended claims of the present invention.
