Abstract
The invention discloses a reluctance device. The reluctance device comprises a shell, an inner pipe body, a lead screw, a magnet, at least one protruding unit and at least one metal part. As the protruding units protruding out of the inner wall surface of the inner pipe body moves along a thread on the surface of the lead screw, the lead screw can drive the inner pipe body to rotate when sliding, and therefore reluctance force is conveniently generated among the magnet, the metal part and a metal pipe body of the shell. In addition, an adjustment unit is arranged to change the distance between the metal part and the magnet, so that the effect of conveniently changing the reluctance force generated among the magnet, the metal part and the metal pipe body of the shell when the magnet rotates is realized.

The press section 272 of whole unit 270, the contractility of the spring 274 pulls on the location division 275 and moves toward the metal tube 212,
The location division 275 is fixed into a corresponding wherein through hole 2123, and then fix the relative Magnet 240 of the metalwork 260
Position, reach the effect for fixing the reluctance force size produced by the magnetoresistive devices 200.
In the present embodiment, the projection unit 250 is the thread surface 232 of a female thread, the female thread and the screw rod 230
It is bonded with each other, so that in the moving process of the screw rod 230, the female thread maintains to be moved along the thread surface 232, with as described above
The linear motion of the screw rod 230 is converted to into the rotary motion of the interior tube body 220.
In addition, in the present embodiment, a coil group 280 can be also included in the magnetoresistive devices 200, the coil group 280 is fixed
In the housing 210, and when the Magnet 240 is driven by the interior tube body 220 and rotated, sense is produced in the coil group 280
Answer electromotive force and form faradic current, that is, magnetic force is converted into into electric power, so as to using connecting line (not shown) connection
Between the external device (ED) (not shown) of coil group 280 and, and the magnetoresistive devices 200 are made to supply power to as a power supply
The external device (ED), and work as the magnetoresistive devices 200 and be applied in a body-building apparatus (not shown), then the external device (ED) can be the body-building
The display screen of equipment, the display screen can be used to show the relevant information of the body-building apparatus.
In sum, magnetoresistive devices of the invention, the projection unit of the internal face of the interior tube body is arranged at by protrusion
Thread surface along the screw rod is moved, and interior tube body rotation can be driven when making the screw slide, so as to can easily in the magnetic
Reluctance force is produced between ferrum, the metalwork and the metal tube of the housing；Additionally, an adjustment unit can be further set, with logical
Cross the adjustment unit change the distance of the metalwork and the Magnet reach easily change the Magnet when Magnet rotates, should
Effect of reluctance force size produced between metalwork and the metal tube of the housing.
The present invention is hereinbefore disclosed with preferred embodiment, but it should be understood by those skilled in the art that, the reality
Apply example to be only used for describing the present invention, and be not construed as limiting the scope of the present invention.It should be noted that such as with the embodiment etc.
The change of effect and displacement, all should be set to be covered by scope of the invention.Therefore, protection scope of the present invention is when with claim
Defined person is defined.
