Problems solved by technology

[0006] In the above-mentioned structure, the driving member 86 is pivotally connected to the center of itself, and is also located in the middle position between the two swinging members 83. Therefore, although the driving member rotates 360°, it touches the two swinging members with its elliptical circumference. A swing member 83 is used to rotate it, but in fact, the number of strokes of the effective adjustment stages of the driving member 86 is only half of the circle; moreover, the two swing members 83 are symmetrically inwardly or outwardly swinging. The swing angle is the same and it is a synchronous movement. The effective stroke of the adjustment of the number of segments on both sides is the distance length, so the distance a between the swing parts on both sides is equal to b, and the adjustment of the speed segment number is small, and the closer the swing is to the magnet, the greater the change. , the more difficult it is to control, and generally the above-mentioned existing structure will increase the range of the segment to facilitate control, which will easily cause the original controllable error range to increase or make the change in the control range not detailed enough

Embodiment 1

[0055]Please refer to Fig. 1~Fig. 3 at first, a kind of sports equipment segmental deceleration magnetic control system provided by the present invention mainly includes: a flywheel body 10, a magnetic control group 20 located in the flywheel body, and a Genset 30.

[0056] The flywheel body 10 is made of aluminum alloy, and it is concavely provided with a chamber 11, which is in the shape of a circular groove, and the inner edge wall of the chamber 11 is equidistantly provided with eight magnetic conductors 12 with magnetic conduction effect. , which can be a magnet. The magnetic conductor 12 is embedded in the inner wall of the container, and its magnetically conductive surface is exposed at the inner edge of the container.

[0057] The magnetic control group 20 is located in the chamber 11, and has two magnetic control units 21, 22, which are arranged oppositely, and can be rotated and deflected respectively, and can be formed with each of the above-mentioned magnetizers 1...

Embodiment 2

[0067] Figure 6 shows Embodiment 2 of the present invention, which differs from Embodiment 1 in that the setting of the magnetron group 20 is offset from the center of the circular groove-shaped chamber 11; and the abutting member 24 is a cam with an irregular profile. The pivot point 241 is arranged at the eccentric position of the cam. The cam can rotate around the pivot point 241; 21, 22 are respectively separated from each magnetizer 12 by different gaps.

Embodiment 3

[0069] Figure 7 shows Embodiment 3 of the present invention. In this embodiment, the magnetron group 20 has an abutting surface 26, which provides a position for abutting against the abutting member 24, and the abutting surface is a predetermined irregular contour. , the curvature of the profile surface changes; the abutment member 24 is elliptical as shown in the figure, and its pivot point 241 is located outside the major axis and the minor axis, so its effective adjustment stroke is the distance of the entire ellipse perimeter length, with Gain the effect of adjusting the number of speed segments of the effective stroke; with the help of the curvature change of the abutting surface 26 and the driving of the abutting member 24, the magnetic controls 21 and 22 can be effectively deflected respectively and have different distances from the magnetic conductor 12 adjustments for changes.

Abstract

The present invention relates to a stepped speed-reducing magnetic control system for sports equipment. Said stepped speed-reducing magnetic control system includes the following several portions: a flywheel self-body, several magnetic conductors, a magnetic control group including two magnetic control components and a supporting component. Said invention also provides the connection mode of all the above-mentioned portions, and also provides the working principle of said magnetic control system and its operation method.

Description

technical field [0001] The invention relates to a magnetic control system, in particular to a magnetic control system used in an indoor exercise car for controlling damping and having a segmented speed regulation structure. Background technique [0002] Due to lack of venues, air pollution, etc., the place where modern people look for exercise is limited by factors such as time and place. If you want to exercise, the easiest way is to do fitness exercises at home; some simple home fitness equipment is common on the market, such as Running machines or exercise bikes can not only take care of family life, but also have no danger of outdoor sports, and are not restricted by the weather, so you can enjoy sports at any time. Especially the indoor exercise bike, which has many features, can simulate riding a bicycle to strengthen muscles and exercise lung capacity, and is safe and convenient without the risk of air pollution. It is a good choice. [0003] In the prior art, the tr...
