Description
Technical field
The present invention relates to field of exercise, mainly relate to a kind of resistance size change system of pedal bicycle, particularly relate to a kind of inner magnetic type magnetic control damper system.
Background technology
At present, existing ECB on the market (being magnetic control damper system, down together) resistance system mainly is divided into external magnetic type ECB and internal magnetization ECB.External magnetic type ECB occupies the less market share relatively, and reason is as follows: the one, and the cost height; The 2nd, at the bottom of the cost performance of product and application place is limited.So internal magnetization ECB is in occupation of the bigger market share.
In addition, the kind of drive of existing internal magnetization ECB is to add that with the small machine decelerator mode of cable wire spurs swing arm, changes resistance by rotary movement.In addition, the systematic comparison complexity of existing internal magnetization ECB also will be used annexes such as cable wire, small machine decelerator except internal magnetization ECB.Each board will be considered how to reserve enough spaces and fix these parts at the beginning of design like this, increase design difficulty and be unfavorable for the optimization of product appearance.
Summary of the invention
The purpose of this invention is to provide a kind of inner magnetic type magnetic control damper system, it adopts parallel mobile mode to change resistance.
The objective of the invention is to be achieved through the following technical solutions:
A kind of inner magnetic type magnetic control damper system, its characteristics are that it comprises: a flywheel; One is positioned at the base of this flywheel; One cover plate that cooperates with this base; The a pair of swing arm that is installed on this base, this swing arm is provided with some magnet in a side of contiguous this flywheel inner ring, and this swing arm can be moved in the space that this base and this cover plate surround, to change the gap between this magnet and this flywheel inner ring; One is installed in motor on this base, that have worm screw, one with the worm gear of this worm engaging; The tooth bar of afterbody gears engaged in one group of travelling gear, a pair of and this group gear by the rotation of this worm gear drives; The a pair of connecting rod that is connected with this tooth bar, the other end of this connecting rod are fixed on this swing arm inner ring, move to drive swing arm; Above-mentioned worm gear, gear, tooth bar are installed on this base.
Wherein, this swing arm main body is a circular arc, and two ends are for directly tabular.
Wherein, a pair of chute is that the center is symmetricly set on this base with this base center of circle, and these swing arm two ends can be moved in this chute.
Wherein, this connecting rod comprises that one is fixed in pull bar in this swing arm is connected this pull bar and this tooth bar with one adjusting rod.
Wherein, be equiped with quoit on this flywheel inner ring.
Positive progressive effect of the present invention is:
1, with low cost, without any need for other annex; Simultaneously can provide big power again, have high cost performance; Both be fit to family expenses, be applicable to also that club used;
2, simple and compact for structure, good looking appearance, easy to use, directly reducing gear is accomplished that ECB is inner and without any need for other annex, just can reconcile resistance very easily as long as the instrument line plugged;
3, the kind of drive is direct transmission, thereby has realized that parallel mobile mode changes resistance, can finish resistance and reconcile in very little scope, and the linear relationship of resistance also relatively meets demand.

The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
Extremely shown in Figure 5 as Fig. 1.This inner magnetic type magnetic control damper system outside comprises that an employing adhesive is glued to the aluminium circle 12 (described aluminium circle also can replace with copper band or other quoits) on flywheel 11 inner rings, one plastic feet 21 and a plastic cover plate 23 are arranged in this aluminium circle 12, and this plastic feet 21 and six screws 22 of plastic cover plate 23 usefulness are fixed together.Useful AB magnet 32 glued together in the swing arm 31, this swing arm 31 is in the centre of plastic feet 21 and plastic cover plate 23 just and leaves certain clearance, when tooth bar 61 motions, swing arm 31 can be moved the chute 211 of plastic feet 21 in, and this is the center symmetrical distribution to chute 211 with the center of circle of this plastic feet 21.The main body of this swing arm 31 is semicircle, and two ends are for directly tabular.
This inner magnetic type magnetic control damper system inside comprises that one is installed in the worm gear 43 of motor 41, on this plastic feet 21, that have worm screw 42 and 42 engagements of this worm screw; Three pairs are meshing with each other and by the gear of these worm gear 42 driven rotary, and the tooth bar 61 of afterbody gear 52 engagements in a pair of and this group gear.This tooth bar 61 is connected with an adjusting rod 62, and adjusting rod 62 other ends connect a pull bar 63, and the other end of this pull bar 63 is fixed on the inner ring of this swing arm 31, and adjusting rod 62 and pull bar 63 constitute connecting rod 60.Above-mentioned worm gear 43, gear and tooth bar 61 are installed on this base 21.
Introduce this system works principle below, after motor 41 energisings, the worm screw 42 on it can drive worm gear 43 and rotate together, and worm gear 43 driven gear 51 again carries out the transmission of torsion.Move simultaneously and equidistantly in order to reach both sides, from gear 51, transmission is divided into two lines, and in order to reach simultaneously equidistant effect, a same gear 51 has been used on the left side more.By gear 51 driven gears 52, gear 52 drives tooth bar 61 like this, and tooth bar 61 drives adjusting rod 62, pull bar 63, finally spurs swing arm 31 with the distance between regulating magnet 32 and the flywheel aluminium circle 12.The variation of distance can cause the variation of magnetic force between the two between magnet 32 and the aluminium circle 12, and this magnetic force native system resistance that will obtain just, so satisfied the demand that obtains different resistances by adjustable range.
The invention is not restricted to above embodiment, also can select other numbers to replace, as long as can reach the effect of transmitting torsion such as the progression of gear.
