Description
Technical field
This utility model relates to the adaptive damping mechanism of a kind of body-building apparatus, refers in particular to one and is easy to regulation and control
The adaptive damping mechanism of the body-building apparatus of damping size.
Background technology
There is multiple treadmill at present, wherein have a flat step treadmill only to pass through runner to treadmill belt with flying wheel
Deboost, application flying wheel auxiliary treadmill belt rotates advances, and it is faster that it rotates gait of march, i.e. generation
The velocity of watch runner is faster, but flying wheel is because having the acceleration of gravity of rotation, makes runner run
In want to stop, will be unable to quickly stop the traveling of treadmill belt, and runner now run quickly stopping
Action, it will cause and throw the danger fallen.
A treadmill is invented, moving of this existing treadmill in order to solve aforesaid problem
Power, all uses single motor and single turns to as power source, to draw the treadbelt of treadmill, and power
Source is nothing more than being DC motor or AC inverter motor two kinds.It is well known, however, that what DC motor can be provided by
Rotating speed dynamic range is limited, it is impossible to infinite extension uses；Although the rotating speed dynamic range of AC inverter motor
Relatively wide, but when extremely low frequency (low speed), the rotor magnetic flux of its motor is the most saturated, causes AC frequency conversion
Motor is difficult to control to, and even has the risk burnt.Therefore use AC inverter motor when low frequency, become
Frequently device can reduce the voltage acting on motor automatically so that it is torsion can decline to a great extent.Because to AC frequency conversion
For motor, below 120HZ is applied to determine torsion, and more than 120HZ is then applied to determine power；Therefore,
When more than 120HZ altofrequency operates, motor is also unable to maintain that the torsion output of high level, the most just limits
Make considerable degree of rotating speed output area.
So existing treadmill power source, no matter being to use DC motor or AC inverter motor, it is carried
The speed of confession is intended to make a choice.Such as；In the extremely low speed that rehabilitation uses, its power source just must be put
Abandon enforcement at a high speed, and get rid of the user run at a high speed.Otherwise, to when the speedy carding process, just must
The rehabilitation user of low speed need to be abandoned.By reducing the restriction that above-mentioned situation is caused, in the race that rehabilitation uses
How step machine, can use the speed output area AC inverter motor compared with wide area, so as to meeting pole needed for rehabilitation
The demand of low speed, and the high-speed requirement needed for body-building.
Owing to above-mentioned existing treadmill all must use motor to drive, and invent aforementioned based on rehabilitation
Passive type treadmill, but it practice, there is danger such as a flat step treadmill, another electronic race
Step machine only has the training of cardio-pulmonary function, and needs circuit board, control panel and motor, and relative cost is relatively
High；In view of aforesaid defect, a kind of magnetic control running exercising machine of invention again；This magnetic control running exercising machine hinders with magnetic control crop rotation
The regulation and control of Buddhist nun, but the speed of uncontrollable speed, and training muscular strength cannot be according to runner's ability at running shape
The most slowly the oneself that to follow one's bent under state adjusts required exercise for power.
