Description
Technical field
The present invention relates to a kind of adaptive damping mechanism of body-building apparatus, refer in particular to one kind and be easy to regulation and control to damp
The adaptive damping mechanism of the body-building apparatus of size.
Background technology
Have a variety of treadmills at present, wherein have a flat step treadmill only with flying wheel by runner to treadmill belt
Deboost, rotate and advance using flying wheel auxiliary treadmill belt, it is faster that it rotates gait of march, i.e. generation
The velocity of watch runner is faster, but flying wheel is because with the acceleration of gravity rotated, making runner in running
In want to stop, will be unable to the quick traveling for stopping treadmill belt, and runner now stops running quick
Action, it will cause to throw the danger fallen.
The problem of in order to solve foregoing and invent a treadmill, the existing treadmill it is dynamic
Power, all using single motor and single steering as power source, to draw the treadbelt of treadmill, and power
Source is nothing more than being two kinds of DC motors or AC inverter motors.It is well known, however, that what DC motors can be provided
Rotating speed dynamic range is limited, it is impossible to which infinite extension is used；Although the rotating speed dynamic range of AC inverter motors
It is relatively wide, but in extremely low frequency (low speed), the rotor magnetic flux easily saturation of its motor, cause AC frequency conversions
Motor is difficult to control to, or even has the risk burnt.Therefore use AC inverter motors when low frequency, become
Frequency device can reduce the voltage for acting on motor automatically, its torsion is declined to a great extent.Because to AC frequency conversions
For motor, below 120HZ is applied to determine torsion, and more than 120HZ is then applied to determine power；Therefore,
When more than 120HZ high-frequencies are operated, motor is also unable to maintain that the torsion output of high level, so just limits
Considerable degree of rotating speed output area is made.
So existing treadmill power source, either using DC motors or AC inverter motors, it is carried
The speed of confession is intended to make a choice.For example；The extremely low speed used in rehabilitation, its power source must just be put
The implementation of high speed is abandoned, and excludes the user run at a high speed.Conversely, to when the speedy carding process, just must
The rehabilitation user of low speed need to be abandoned.To reduce the limitation caused by above-mentioned situation, the race used in rehabilitation
Step machine, more can be using speed output area compared with the AC inverter motors of wide area, pole needed for so as to meeting rehabilitation
The demand of low speed, and the high-speed requirement needed for body-building.
Because above-mentioned existing treadmill must all use motor to drive, and invent foregoing based on rehabilitation
Passive type treadmill, but in fact, as a flat step treadmill have danger, another electronic race
Step machine only has the training of cardio-pulmonary function, and needs circuit board, control panel and motor, relative cost compared with
It is high；In view of foregoing defect, invents a kind of magnetic control running exercising machine again；The magnetic control running exercising machine is hindered with magnetic control crop rotation
The regulation and control of Buddhist nun, but the speed of uncontrollable speed, and training muscular strength can not be according to runner's ability in running shape
Soon will follow one's bent self required exercise for power of adjustment slowly under state.
The content of the invention
To solve above-mentioned problem of the prior art, the present invention provides a kind of adaptive damping machine of body-building apparatus
Structure, the damping of the Damping rotation shaft is driven by first transmission rope on first change pulley of main shaft
Device produces relative damping effect and rotated, and to train runner leg muscular endurance, first transmission rope passes through this
First adaptive damping mechanism first change pulley either arrange in pairs or groups simultaneously second transmission rope by this
Gear ratio regulation and control rotating speed of the two adaptive damping mechanisms on second change pulley, and coordinate the damping unit
Magnetic control wheel or fan damping action, to expand control dampening range, are suitable for the muscular strength of different degrees of runner
Training, when user velocity slows down, it is possible to use the resistance of the damping unit, makes treadmill belt or connecting rod
/ pedal slows down and quickly stopped, in addition to security, does not need motor to drive when various places are used
Dynamic and driven by power.
