Magnetic Force Reducer

Abstract

A magnetic force reducer is mounted on a holder having a belt and contains: a drive shaft, multiple rotators, and a magnetic conduct ring. The drive shaft is configured to rotate a rotatable disc, and the rotatable disc has multiple rotation segments and multiple first support portions. The multiple rotators are rotatably connected on two surfaces of the rotatable disc in parallel. A respective one rotator includes a swing arm rotatably connected with a respective one rotation segment and having a conductive rotation element and a second support portion. A resilient element is connected between the second support portion and a respective one first support portion of the rotatable disc. The magnetic conduct ring is fitted around the conductive rotation element of the respective one rotator to produce a magnetic field.

Claims

1. A magnetic force reducer being mounted on a holder having a belt and comprising: a drive shaft configured to rotate a rotatable disc, and the rotatable disc having multiple rotation segments and multiple first support portions which are arranged on multiple positions of the rotatable disc respectively; multiple rotators rotatably connected on two surfaces of the rotatable disc in parallel, a respective one rotator including a swing arm, wherein a first end of the swing arm is rotatably connected with a respective one rotation segment, and the swing arm has a conductive rotation element disposed on a second end thereof, the swing arm further has a second support portion defined on a predetermined position of the swing arm between the conductive rotation element and the respective one rotation segment, and a resilient element is connected between the second support portion and a respective one first support portion of the rotatable disc; a magnetic conduct ring fitted around the conductive rotation element of the respective one rotator to produce a magnetic field so that when the conductive rotation element rotates on the respective one rotator, the conductive rotation element moves to or over the magnetic conduct ring.

2. The magnetic force reducer as claimed in claim 1, wherein three rotators are arranged on each of the two surfaces of the rotatable disc.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] With reference to FIGS. 2 to 6, a magnetic force reducer 1 according to a preferred embodiment of the present invention is mounted on a holder A1 having a belt A2 and comprises:

[0020] a drive shaft 40 configured to rotate a rotatable disc 50, and the rotatable disc 50 having multiple rotation segments 21 and multiple first support portions 32 which are arranged on multiple positions of the rotatable disc 50 respectively;

[0021] multiple rotators 20 rotatably connected on two surfaces of the rotatable disc 50 in parallel, a respective one rotator 20 including a swing arm 22, wherein a first end of the swing arm 22 is rotatably connected with a respective one rotation segment 21, and the swing arm 22 has a conductive rotation element 23 disposed on a second end thereof, the swing arm 22 further has a second support portion 31 defined on a predetermined position of the swing arm 22 between the conductive rotation element 23 and the respective one rotation segment 21, and a resilient element 30 is connected between the second support portion 31 and a respective one first support portion 32 of the rotatable disc 50, wherein three rotators 20 are arranged on each of the two surfaces of the rotatable disc 50;

[0022] a magnetic conduct ring 10 fitted around the conductive rotation element 23 of the respective one rotator 20 to produce a magnetic field so that when the conductive rotation element 23 rotates on the respective one rotator 20, it moves to or over the magnetic conduct ring 10.

[0023] Thereby, the magnetic force reducer 1 is capable of producing energy by using the multiple rotators 20 and the rotatable disc 50 so that the multiple rotators 20 move to or over the magnetic conduct ring 10 quickly, thus stopping vehicle effectively. Preferably, when the respective rotator 20 moves to the magnetic conduct ring 10, the conductive rotation element 23 enters the magnetic conduct ring 10 to maintain braking effect.

[0024] While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. The scope of the claims should not be limited by the preferred embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
