Description
Technical field
The present invention relates to a kind of magnetic control system, particularly relate to a kind ofly be used in the cycling-trainer, in order to control damping size and have the magnetic control system of segmentation speed regulating structure.
Background technique
Owing to reasons such as lack of space, atmospheric pollutions, the place that the modern seeks motion is subject to factors such as time place, wants to take exercises, and the simplest mode is in exactly and is done body building; More common on the market simple family fitness equipment as running machine or exercycle etc., not only can be taken into account family life, and not have the danger of outdoor exercises, not limited by weather, can enjoy the enjoyment of motion at any time.Especially cycling-trainer, it has multinomial characteristics, but the riding simulation bicycle strengthening muscle, to temper vital capacity, and safe ready does not have the anxiety of atmospheric pollution again, is good selection.
In the prior art, the drive mechanism of exercycle, can be divided into single turntable structure, and two turntable structure, wherein two turntable structures mainly are provided with a main turntable in vehicle frame front end below, one flywheel is located at this below, vehicle frame rear end, and by a belt transmission, the rotation synchronously with the rotation of main turntable cooperates one to be installed near the damping device between main turntable or the flywheel, utilize magnetic control that this flywheel or main turntable are produced electromagnetic induction, come exercycle is carried out the segmentation speed governing and make it produce resistance.
Generally speaking, the design of exercycle is main emphasis with use and function all, need stress the requirement of ergonomics and Security simultaneously, utilize the reinforcement on the function and make product have otherness, increase its surcharge, in the hope of possessing suitable competitive ability or prolong the product life cycle on city's field boundary, wherein modal function is flywheel speed governing and damping etc.
The magnetic control means 80 that has the magnetic control function in the background technique, consult Figure 12～Figure 14, its structure mainly comprises: a room 81, the its inner rim wall is equipped with a magnetic conductive part 82, also be provided with two swing parts 83, these two swing parts 83 are installed in predetermined position in this room 81, and can make rotary oscillation thereon, wherein, two swing parts 83 have a curved arc piece 831 respectively, and in its intrados linked block 832 that radially is shaped respectively, and collude hole 833, one elastic components 84 and be fixedly connected on colluding between the hole 833 on these two swing parts being provided with one on two linked blocks 832 respectively; Two magnetic patch groups 85, be fixedly arranged on the position of each swing part 83 respectively in the face of this magnetic conductive part 82, one actuator 86, be one and can paste the microscler driving block that touches in each swing part 83,85 outer arced surface that are fixedly arranged on described two curved arc pieces 831 respectively of two magnetic patch groups, in the face of this magnetic conductive part 82, to produce Magnetic Induction: by the rotation of this actuator 86, change conflict position with two linked blocks 832, promote two swing parts 83 and produce swing around its pivot-connecting position respectively, and then the distance between adjustment magnetic patch group 85 and the magnetic conductive part 82, be that the magnetic resistance is more little when distance is big more, when big more apart from more little then magnetic resistance.
In the said structure, this actuator 86 is articulated in the center of himself, the also neutral position between two swing parts 83, so, though this actuator is done 360 ° of rotations, contact two swing parts 83 respectively with its oval circumference, make it rotation, but in fact effective adjustment hop count stroke of rotating a circle of this actuator 86 only is half of circumference; Moreover, two swing parts 83 are to be symmetric mode or swing outwardly inwardly, its pendulum angle is identical and for being synchronized with the movement, its both sides hop count is adjusted effective travel and is gap length, so the part spacing a that rolls to each side equals b, it is little that the speed segments is adjusted variable quantity, and because of swing part is more healed big near the magnet variable quantity, more difficult control, and general above-mentioned existing structure can become this segmentation limit greatly in order to control, causes former may command margin of error to strengthen or make the not enough refinement of this control range variable quantity easily.
