The specific embodiment
A kind of electric damper for intelligent fitness equipment, as shown in Figure 2, it comprises three-phase bridge rectifier circuit, digital voltage regulator, intelligent control chip, resistance Buddhist nun load and machine driving input; By generator output voltage and electric current; Through the digitlization mu balanced circuit, export stable voltage, the voltage of Voltage stabilizing module output is controlled by intelligent control chip; Voltage inputs to resistance Buddhist nun load; Power consumption is in resistance Buddhist nun load, and described resistance Buddhist nun load is connected with the damping digital control circuit, and described resistance Buddhist nun load is connected with the damping intelligence control circuit.The kinetic energy that body-building apparatus of the present invention produces comes the pushing generator rotation through a series of mechanical mechanisms, and the mechanical energy of fitness equipment is deducted energy conversion loss, all changes into the electric energy of alternating current generator.Because generator output voltage and electric current all are variable,, export stable voltage through the digitlization mu balanced circuit; Conversion efficiency is wherein calculated at inherent damping, ignores, and the voltage of Voltage stabilizing module output is by intelligent control chip (intelligent IC: control integrated circuit); Voltage inputs to the resistance Buddhist nun load of back, and electric energy will all consume in resistance Buddhist nun load basically, and resistance Buddhist nun load can be active load or passive load; The present invention is example with the passive load; Therefore, the big young pathbreaker of the electric energy that consumes on the controlling resistance is the key technology of control damping size, because resistance consumption power P=I*I*R; So perhaps P=V*V/R is the damping of the just corresponding adjustment fitness equipment of the output voltage of control figure Voltage stabilizing module.
As shown in Figure 3; Be damping digital control circuit of the present invention; It comprises: Based Intelligent Control IC, high direct voltage, the controlled low pressure of direct current, large power, electrically damping load, and in the circuit, Based Intelligent Control IC can recently realize through the duty of control MOSFET (FET) ON time; The function of the output of adjustment Voltage stabilizing module, wherein the FB pin is the voltage feedback.Voltage regulating module can be adjusted to fixing value with voltage according to program setting, and the damping control that voltage satisfies different motion speed and motion stage also can be dynamically adjusted in the fixedly damping of fitness equipment.
Based Intelligent Control IC sampling feedback voltage, feedback voltage compares with programmed values through digitlization, for just, explains that feedback voltage is higher as if difference, reduces the dutycycle that goes up pipe MOSFET so, is complementary owing to manage the conducting of MOSFET up and down and end.Output voltage U out=D*Vin, wherein D is the dutycycle that goes up pipe, the setting value of the middle voltage of intelligent control program can be from the curing value of program, also can be from the input value of fitness equipment panel.The another kind of pattern of intelligent exercising apparatus is the sampling input voltage, like Fig. 4, and perhaps input speed signal; Size according to input voltage or rotating speed; Judge user's exercise intensity (input power of the big more correspondence of exercise intensity is big more, otherwise exercise intensity is low more, and input power is low more) enforcement intelligent damping.If judge that input voltage uprises or rotating speed improves, explain that damping is too small, Based Intelligent Control IC increases damping automatically.Otherwise, reduce damping automatically.Damping increases the algorithm that reduces and meets the ergonomic custom, seamlessly transits, and avoids damping to adjust motion-affecting comfort level and the exercise habit of taking exercise.
The damping control circuit of ohmic load, the circuit of this embodiment are formed and are comprised that generator M1, three-phase commutation bridge BR1, energy storage filter capacitor C1, stabilized switch pipe Q1, Q2, inductance L 1, divider resistance R1, R2, R3, R4, output filter capacitor C2, high-power damping loads R and Based Intelligent Control IC form.Wherein generator can be two phase or direct current generators; Corresponding rectifier bridge be two phases or non-rectifying bridge; The output of rectifier bridge connects the D utmost point of stabilized switch pipe Q1, and the D utmost point of Q2 is received the S utmost point of Q1, and links to each other with inductance L 1; The S utmost point ground connection of Q2, the grid of Q1, Q2 are received the output pin of 2 pwm signals of control IC.The other end of inductance L 1 is received on the high-power damping loads R.C1, C2 receive input direct voltage respectively and output dc voltage carries out filtering.R1, R2 form bleeder circuit and link on the output voltage V out, and with the FB1 pin of dividing point connection of intelligent control IC, R3, R4 form bleeder circuit and link on the output voltage V in, and with the FB2 pin of dividing point connection of intelligent control IC.
A kind of control method of electric damper for intelligent fitness equipment; Cooperate Fig. 4, shown in Figure 5, at first the mechanical energy with fitness equipment is input to generator M1 through transmission conversion rotating mechanical energy, and M1 exports three-phase electricity; Three-phase electricity is rectified into direct current output Vin through three-phase commutation bridge; The size of Vin depends on the rotating speed of motor M 1 and rotation input, and (generally can make Vin be in high voltage through speeder) Q1, Q2 form the synchronous buck circuit, and the ON time of Q1 and Q2 is complementary.The conducting dutycycle D of Q1 is exported by Based Intelligent Control IC.L1 is an output inductor, and C1 is a filter capacitor, this moment Vout=Vin*D, Based Intelligent Control IC samples Vout to the FB1 pin, and carries out analog-to-digital conversion and handle, and exports according to the input of control panel adjustment dutycycle.Dutycycle is big more, and output voltage is high more, and the power consumption of resistance R is big more; The damping of fitness equipment is also big more; In the full-automatic damping control of intelligence fitness equipment, the input of damping control is not from control panel, but has the signals such as input voltage feedback of FB2 sampling by oneself; Program is adjusted the damping size automatically according to the comfort level of people's motion.
Above-mentioned intelligent electric resistance Buddhist nun control circuit, can be arbitrarily the accurate kinetic damping of control fitness equipment, no matter at low speed, motion process at a high speed, its damping all is a program controlled.The user only need set the fitness equipment that the panel input just can obtain being fit to user's displacement intensity as required; Because Q1, Q2 are on off state; So power consumption is very little, the resistance Buddhist nun load R that unique power consumption is bigger also is convenient to position and heat radiation that the designer arranges damping loads.With respect to existing traditional damping control scheme (as shown in Figure 1); The present invention can be according to the various intelligent damping control models of program automatic setting; Have high intelligent specificly, it is little to have a noise than traditional mechanical damping fitness equipment simultaneously, advantages such as damping adjustment aspect.
Above embodiment only supplies to explain the present invention's usefulness, but not the restriction to inventing, the technical staff in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present invention, should be limited each claim.
